[0045] FIG. 1 is a schematic structural diagram of a sunshade umbrella according to some embodiments of the present disclosure. FIG. 2 is a schematic structural diagram of the sunshade umbrella from another perspective according to some embodiments of the present disclosure.

[0046] The present disclosure provides a sunshade umbrella. As shown in FIGS. 1 and 2, the sunshade umbrella includes an umbrella pole 53, an umbrella frame 54, and a base 3. The umbrella pole 53 is disposed on the base 3, and the umbrella frame 54 is connected to the umbrella pole 53. The umbrella pole 53 is provided with a hand-crank portion 9, a pull rope 29 is wound around the hand-crank portion (see FIG. 3). The hand-crank portion 9 drives the umbrella frame 54 to deploy or retract by retracting or releasing the pull rope 29.

[0047] The umbrella pole 53 is a columnar structure that supports the entire sunshade umbrella. In some embodiments, the umbrella pole 53 is mounted on the base 3 in a direction vertical to a ground and connected to the umbrella frame 54. In some embodiments, the umbrella pole 53 may be configured to support the umbrella frame 54 and related components, provide a guiding channel for the pull rope 29, and adjust a height of the sunshade umbrella.

[0048] The umbrella frame 54 is a framework structure that supports a canopy. In some embodiments, the umbrella frame 54 is connected to the umbrella pole 53 and the pull rope 29. In some embodiments, the deployment or retraction of the umbrella frame 54 enables the canopy to open or close, thereby achieving a sunshade function.

[0049] The base 3 is a load-bearing structure that stabilizes the sunshade umbrella and prevents tipping. In some embodiments, the base 3 is located at a bottommost part of the sunshade umbrella and contacts the ground.

[0050] The hand-crank portion 9 (also referred to as a crank) is a component configured to control the retraction and release of the pull rope 29. In some embodiments, the hand-crank portion 9 is disposed on the umbrella pole 53, and the pull rope 29 is wound around the hand-crank portion 9. In some embodiments, the hand-crank portion 9 may drive the pull rope 29 to deploy or retract the umbrella frame 54.

[0051] The pull rope 29 (also referred to as an umbrella rope) is a flexible rope that transmits a driving force. In some embodiments, an end of the pull rope 29 is wound around the hand-crank portion 9, and another end of the pull rope 29 passes through the umbrella pole 53 and connects to the umbrella frame 54. In some embodiments, the pull rope 29 transmits the driving force from the hand-crank portion 9 to the umbrella frame 54, enabling the umbrella frame 54 to deploy or retract.

[0052] In some embodiments, when the hand-crank portion 9 is rotated forward to release the pull rope 29, the pull rope 29 pulls the umbrella frame 54 under the guidance of the umbrella pole 53, causing the umbrella frame 54 to retract. Conversely, when the hand-crank portion 9 is rotated in reverse to retract the pull rope 29, the pull rope 29 pulls the umbrella frame 54 under the guidance of the umbrella pole 53, causing the umbrella frame 54 to deploy.

[0053] More descriptions regarding the sunshade umbrella may be found in FIGS. 3-16 and the related descriptions.

[0054] FIG. 3 is a schematic diagram of a routing path of a pull rope according to some embodiments of the present disclosure.

[0055] In some embodiments, as shown in FIGS. 1-3, the sunshade umbrella further includes a handle 4. The umbrella frame 54 includes upper umbrella rods 2 and lower umbrella rods 1, and the umbrella pole 53 includes a lower vertical rod 6 and an upper vertical rod 7. The upper umbrella rods 2 are connected to the lower umbrella rods 1 via rotating bars 5. The lower vertical rod 6 is disposed above the base 3, and the lower vertical rod 6 is connected to the upper vertical rod 7 via a connecting member 8. The hand-crank portion 9 is disposed on the upper vertical rod 7, and a rope reel 10 is disposed inside the hand-crank portion 9. The handle 4 is disposed above the hand-crank portion 9, and a crank 32 is disposed on the hand-crank portion 9.

[0056] The handle 4 (also referred to as a handrail shell) is a component configured to adjust its own position on the umbrella pole 53 for altering a tilt angle of the umbrella frame 54. In some embodiments, the handle 4 may be mounted on the upper vertical rod 7 above the hand-crank portion 9, i.e., the handle 4 is separately arranged from the hand-crank portion 9. Understandably, separating the handle 4 from the hand-crank portion 9 facilitates easier retraction and deployment of the sunshade umbrella.

[0057] A lower umbrella rod 1 is a rod-shaped structure located at a lower portion of the umbrella frame 54 and supports a lower portion of the canopy. An upper umbrella rod 2 is a rod-shaped structure located at an upper portion of the umbrella frame 54 and supports an upper portion of the canopy. In some embodiments, each of the upper umbrella rods 2 corresponds to one of the lower umbrella rods 1.

[0058] In some embodiments, each of the upper umbrella rods 2 is connected to a corresponding lower umbrella rod 1 via a rotating bar 5, and two ends of the rotating bar 5 are fixed to corresponding positions on the upper umbrella rod 2 and the lower umbrella rod 1, respectively.

[0059] A rotating bar 5 is an elongated component that connects the upper umbrella rod 2 and the lower umbrella rod 1 and transmits rotational motion, enabling synchronized rotation between the upper umbrella rod 2 and the lower umbrella rod 1. In some embodiments, a count of the rotating bars 5 is greater than or equal to the count of the lower umbrella rods 1 or upper umbrella rods 2. When the lower umbrella rod 1 rotates, the rotating bar 5 drives the upper umbrella rod 2 to rotate synchronously, thereby facilitating coordinated retraction and deployment of the canopies (i.e., the upper canopy and the lower canopy) on the upper umbrella rod 2 and the lower umbrella rod 1.

[0060] The lower vertical rod 6 is a columnar structure located at a lower portion of the umbrella pole 53. In some embodiments, the lower vertical rod 6 is connected to the base 3, and connected to the upper vertical rod 7 via the connecting member 8. Exemplary connecting members 8 may include, but are not limited to, a thumb screw, a snap fastener, etc.

[0061] The upper vertical rod 7 is a columnar structure positioned at the upper portion of the umbrella pole 53. In some embodiments, the upper vertical rod 7 is provided with the handle 4 and the hand-crank portion 9. In some embodiments, the upper vertical rod 7 may have a hollow structure to provide a guiding channel for the pull rope 29.

[0062] The rope reel 10 is a wheel-like component housed within the hand-crank portion 9 and configured to retract or release the pull rope 29. In some embodiments, the pull rope 29 is wound around the rope reel 10 in the hand-crank portion 9.

[0063] In some embodiments, the rotating bar 5 ensures that when the lower umbrella rod 1 rotates, the upper umbrella rod 2 rotates synchronously, thereby facilitating coordinated retraction and deployment of the canopies on both the lower umbrella rod 1 and the upper umbrella rod 2. The connecting member 8 provides stable fixation between the lower vertical rod 6 and the upper vertical rod 7. The upper vertical rod 7 is provided with the hand-crank portion 9 and the handle 4, which are spatially separated. During canopy operation, rotating the crank 32 on the hand-crank portion 9 directly controls the retraction/release of the pull rope 29, thereby driving the lower umbrella rod 1 to retract/deploy and consequently operating the canopy. The position of the handle 4 is adjustable along the upper vertical rod 7 to change the tilt angle of the deployed canopy. Rotation of the crank 32 drives the rope reel 10 to rotate.

[0064] In some embodiments of the present disclosure, the upper vertical rod is provided with the hand-crank portion and the handle that are separately arranged. During retraction, rotating the crank on the hand-crank portion directly releases the pull rope, causing the lower umbrella rod to retract and consequently fold the canopy. The position of the handle along the upper vertical rod is adjustable to control a canopy tilt angle during deployment of the umbrella frame.

[0065] FIG. 4 is a schematic structural diagram of an upper vertical rod, a lower vertical rod, and a connecting member according to some embodiments of the present disclosure.

[0066] In some embodiments, as shown in FIGS. 3-4, a lower threaded hole 11 is formed on the lower vertical rod 6, an upper threaded hole 12 is formed on the upper vertical rod 7, and the upper threaded hole 12 is connected to the lower threaded hole 11 via the connecting member 8. A first pulley 13 and a second pulley 14 are disposed inside the upper vertical rod 7, and the second pulley 14 is positioned above the first pulley 13. A closure cap is provided on the upper vertical rod 7. The term above refers to a direction away from the ground, below refers to a direction toward the ground.

[0067] In some embodiments, a top end of the lower vertical rod 6 inserts into a bottom end of the upper vertical rod 7. After the lower threaded hole 11 is aligned with the upper threaded hole 12 according to operational requirements, the connecting member 8 is inserted into the aligned lower threaded hole 11 and the upper threaded hole 12, thereby achieving a secure connection at the desired height.

[0068] In some embodiments, an outer diameter of the lower vertical rod 6 is less than or equal to an inner diameter of the upper vertical rod 7, allowing the lower vertical rod 6 to insert into the upper vertical rod 7.

[0069] In some embodiments, a plurality of upper threaded holes 12 may be arranged on a side of the upper vertical rod 7, uniformly distributed along a length direction of the side of the upper vertical rod 7 at a first preset spacing.

[0070] The first preset spacing refers to a distance between adjacent upper threaded holes 12. In some embodiments, the first interval may be set manually based on experience or actual requirements. For example, the first preset spacing may be 3 cm, 5 cm, or 10 cm.

[0071] In some embodiments, a plurality of lower threaded holes 11 may be arranged on a side of the lower vertical rod 6, uniformly distributed along a length direction of the side of the lower vertical rod 6 at a second preset spacing.

[0072] The second preset spacing refers to a distance between adjacent lower threaded holes 11. In some embodiments, the second interval may be set manually based on experience or actual requirements. For example, the second preset spacing may be 3 cm, 5 cm, or 10 cm. In some embodiments, the first preset spacing and the second preset spacing may be the same or different.

[0073] The first pulley 13 refers to a pulley installed inside the upper vertical rod 7 at the same height as the rope reel 10.

[0074] The second pulley 14 refers to a pulley installed at a top end of the upper vertical rod 7.

[0075] In some embodiments, an end of the pull rope 29 is wound around the hand-crank portion 9, and another end of the pull rope 29 horizontally extends to and wraps around the first pulley 13, then vertically extends to and wraps around the second pulley 14, and finally passes through the umbrella pole 53 to connect with the umbrella frame 54.

[0076] The closure cap 15 is a component installed at the top end of the upper vertical rod 7 to seal a top opening of the upper vertical rod 7. This configuration prevents contaminants like dust or rainwater from entering an interior of the upper vertical rod 7.

[0077] In some embodiments, as shown in FIG. 1, the lower vertical rod 6 includes a plurality of sleeve sections forming a telescopic structure. Rotary self-locking buckles 48 are disposed at junctions between the plurality of sleeve sections, and the rotary self-locking buckles 48 lock telescopic positions of the plurality of sleeve sections by rotation.

[0078] The plurality of sleeve sections are concentrically nested tubular components with progressively decreasing diameters. For example, the plurality of sleeve sections may include multi-stage nested metal tubes. In some embodiments, counts of the sleeves sections and their diameters may be set manually based on experience or actual requirements. For example, the lower vertical rod 6 may include three sleeve sections with diameters of 32 mm, 28 mm, and 24 mm respectively to form the telescopic nested structure.

[0079] A rotary self-locking buckle 48 refers to a fastening structure including a fixing component and a rotating component installed at a junction between the sleeve sections. In some embodiments, at each junction between the sleeve sections, the fixing component connects to an outer sleeve section, and the rotating component connects to an inner sleeve section. Through clockwise/counterclockwise rotation of the rotating component, the rotating component engages or disengages with the fixed component, thereby locking or unlocking the telescopic position. This configuration ensures the lower vertical rod 6 maintains stability after adjustment. The telescopic position of a sleeve section refers to a position of the sleeve section after extension or retraction.

[0080] In some embodiments, after the rotary self-locking buckles 48 are unlocked and the lower vertical rod 6 is pulled upward to a first predetermined height, the rotary self-locking buckles 48 at junctions of extended sleeve sections are locked, so that the lower vertical rod 6 remains stable at the first predetermined height. In some embodiments, after the rotary self-locking buckles 48 are unlocked and the lower vertical rod 6 is pushed downward to a second predetermined height, the rotary self-locking buckles 48 at junctions of retracted sleeve sections are locked, so that the lower vertical rod 6 remains stable at the second predetermined height. In some embodiments, after the rotary self-locking buckles 48 are unlocked and the lower vertical rod 6 is pushed downward to the bottom of the lower vertical rod 6, all of the sleeve sections are retracted, achieving compact storage of the lower vertical rod 6.

[0081] The first predetermined height and the second predetermined height refer to preset heights of the umbrella pole. In some embodiments, these heights may be set based on user requirements and practical usage conditions.

[0082] It should be noted that the telescopic structure formed by the sleeve sections can be manually operated by the user (through pulling up or pushing down) or driven by a mechanical device (e.g., a motor), with no specific limitations imposed in the present disclosure.

[0083] In some embodiments of the present disclosure, the lower vertical rod 6 includes a plurality of sleeve sections forming the telescopic structure, which not only facilitates compact storage of the lower vertical rod 6 through sleeve retraction, but also enables adjustment of the height of the umbrella pole during use through extension/retraction of the lower vertical rod 6, thereby achieving overall height adjustment of the sunshade umbrella.

[0084] FIG. 5 is a schematic structural diagram of an interior of a handle according to some embodiments of the present disclosure.

[0085] In some embodiments, as shown in FIG. 5, a movable wheel 16 is disposed inside the handle 4, the movable wheel 16 is connected to the upper vertical rod 7 via a wheel bar 17, and the movable wheel 16 is in contact with the upper vertical rod 7. A hand-press portion 18 is disposed on a side of the movable wheel 16. The hand-press portion 18 is connected to the handle 4 via a restriction bar 19, and a first spring is 20 disposed between the hand-press portion 18 and the handle 4. The hand-press portion 18 is provided with a latch bar 21, which is connected to the upper threaded hole 12.

[0086] The movable wheel 16 refers to a pulley disposed inside the handle 4 that facilitates movement of the handle 4.

[0087] The first spring 20 is an elastic component positioned between the hand-press portion 18 and the handle 4.

[0088] In some embodiments, the wheel bar 17 provides stable mounting for the movable wheel 16 within the handle 4, allowing movement of the movable wheel 16 along the wheel bar 17 to facilitate movement of the handle 4 on the upper vertical rod 7 through the movable wheel 16. The restriction bar 19 maintains a secure connection between the hand-press portion 18 and the handle 4. The hand-press portion 18 rotates within the handle 4 along the restriction bar 19. When the handle 4 is moved, the hand-press portion 18 is first pressed to further compress the first spring 20, thereby disengaging the latch bar 21 from the upper threaded hole 12. After adjusting the position of the handle 4, the hand-press portion 18 is released to allow a portion of the first spring 20 to rebound, causing the latch bar 21 to engage with a different upper threaded hole 12 to achieve movement of the handle 4, thereby adjusting the canopy tilt angle through the handle 4. When the hand-press portion 18 is not pressed, an elastic force of the first spring 20 maintains the latch bar 21 securely within the upper threaded hole 12.

[0089] FIG. 6 is a schematic structural diagram of a rope reel, a retaining spring, and a hand-crank portion according to some embodiments of the present disclosure.

[0090] In some embodiments, as shown in FIGS. 3 and 6, the closure cap 15 is connected to a first inclined rod 22, a second inclined rod 23 is connected to the handle 4, the first inclined rod 22 and the second inclined rod 23 are interconnected via a connecting portion 24. A third pulley 25 is disposed inside the first inclined rod 22, and a fourth pulley 26 is disposed inside the second inclined rod 23. The second inclined rod 23 is connected to a middle rod head 27, and a fifth pulley 28 is disposed inside the middle rod head 27. The pull rope 29 is wound around the rope reel 10. The pull rope 29 passes sequentially through the rope reel 10, the first pulley 13, the second pulley 14, the third pulley 25, the fourth pulley 26, and the fifth pulley 28 to connect to a lower rod head 30. A retaining spring 31 is disposed on a side of the rope reel 10.

[0091] The first inclined rod 22 (also referred to as a suspension arm) refers to an oblique rod body having an end connected to the closure cap 15 and another end connected to the second inclined rod 23 via the connecting portion 24. Exemplary connecting portions 24 include, but are not limited to, a pin hinge, a ball joint, or the like.

[0092] The second inclined rod 23 (also referred to as a support arm) is an oblique rod body having an end connected to the handle 4 and another end connected to the middle rod head 27.

[0093] The third pulley 25 refers to a pulley installed inside an end of the first inclined rod 22 close to the connecting portion 24.

[0094] The fourth pulley 26 refers to a pulley installed at a middle portion of the second inclined rod 23.

[0095] The middle rod head 27 refers to a connecting member that connects the lower umbrella rod 1, the second inclined rod 23, and a round rod 34. For further details regarding the round rod 34, refer to FIG. 8 and the related description.

[0096] The fifth pulley 28 refers to a pulley installed inside an end of the second inclined rod 23 close to the middle rod head 27.

[0097] The lower rod head 30 refers to a connecting member located below the middle rod head 27. In some embodiments, the lower rod head 30 is connected to the round rod 34 and a connecting rod 35. For further details regarding the connecting rod 35, refer to the description related to FIG. 8.

[0098] In some embodiments, the second inclined rod 23 has an opening at its middle portion for the pull rope 29 to pass through. The pull rope 29 extends out from the first inclined rod 22, passes through the opening, and enters the second inclined rod 23. In some embodiments, an end of the pull rope 29 is wound around the hand-crank portion 9, and another end of the pull rope 29 horizontally extends to the first pulley 13 and is wound around the first pulley 13, then extends upward to the second pulley 14 and is wound around the second pulley 14, passes through the first inclined rod 22 and is wound around the third pulley 25, passes through the connecting portion 24 and is wound around the fourth pulley 26, passes through the second inclined rod 23 and is wound around the fifth pulley 28, and finally passes through the middle rod head 27 and the round rod 34 to connect with the lower rod head 30, thereby achieving connection with the umbrella frame 54.

[0099] The retaining spring 31 refers to an elastic component installed on a side of the rope reel 10. In some embodiments, the retaining spring 31 applies a friction force generated by its elasticity to an inner wall of the hand-crank portion 9, preventing the rope reel 10 from rotating freely when no external force is applied (e.g., when the crank 32 is not rotated). This configuration ensures stable length retention of the pull rope 29 after retraction or releasing, thereby maintaining the canopy in an expanded or collapsed state and avoiding displacement of the canopy due to unintended rotation of the rope reel 10.

[0100] In some embodiments, a portion of the lower vertical rod 6 is located inside the upper vertical rod 7, and the connecting member 8 is connected to the upper threaded hole 12 and the lower threaded hole 11, thereby securing the connection between the lower vertical rod 6 and the upper vertical rod 7. The closure cap 15 seals the upper vertical rod 7, and an end of the first inclined rod 22 is rotatable on the closure cap 15 while another end of the first inclined rod 22 is rotatable at the connecting portion 24. An end of the second inclined rod 23 is rotatable on the handle 4, and another end of the second inclined rod 23 is rotatable on the middle rod head 27, thereby facilitating the expansion and retraction of the canopy.

[0101] In some embodiments, when deploying or retracting the sunshade umbrella, the crank 32 may be rotated to drive the rope reel 10 for retraction or release. The pull rope 29 extends along the rope reel 10, the first pulley 13, the second pulley 14, the third pulley 25, the fourth pulley 26, and the fifth pulley 28, and connects to the lower rod head 30, thereby allowing the hand-crank portion 9 to control the deployment and retraction of the canopy. The rope reel 10 is fixedly connected to the retaining spring 31, which prevents unintended rotation of the rope reel 10 through friction between the retaining spring 31 and the hand-crank portion 9.

[0102] FIG. 7 is a schematic structural diagram of a first motor, a first controller, and a torque sensor according to some embodiments of the present disclosure.

[0103] In some embodiments, as shown in FIG. 7, a first motor 51 is coaxially installed at an axial end of the rope reel 10, and the crank 32 is mechanically coupled to the rope reel 10. A first controller 52 is disposed inside the base 3 or the crank 32, and the crank 32 is provided with a control panel. The first controller 52 is electrically connected to the control panel and the first motor 51. The first controller 52 is configured to, in response to receiving a frame deployment/retraction command acquired by the control panel, drive the first motor 51 to rotate forward or in reverse, to control the pull rope 29 to drive the umbrella frame 54 to retract or deploy.

[0104] The first motor 51 refers to a motor installed at the axial end of the rope reel 10. For example, the first motor 51 may include a constant-speed motor, a direct current (DC) geared motor, or the like.

[0105] A controller refers to a component configured to receive external commands and control various parts of the sunshade umbrella to achieve automated operation. The first controller 52 is configured to control the first motor 51.

[0106] In some embodiments, a rotating shaft of the crank 32 extends into an interior of the hand-crank portion 9 and meshes with a rotating shaft of the rope reel 10 via a gear. The rotating shafts of the crank 32 and the rope reel 10 may be coaxially fixed. When the crank 32 is rotated, the mechanically coupled rope reel 10 rotates accordingly, thereby retracting or releasing the pull rope 29 to drive the umbrella frame 54 to deploy or retract.

[0107] The control panel refers to a button panel provided on the crank 32. In some embodiments, the control panel may include a button with multiple operation modes. For example, a long press may adjust a degree of frame deployment/retraction, three consecutive short presses may trigger full-range frame deployment/retraction, and pressing the button again during automated frame deployment/retraction may stop the deployment/retraction of the umbrella frame 54. In some embodiments, the control panel may include multiple buttons for separately acquiring commands such as deployment of the umbrella frame 54, retraction of the umbrella frame 54, and stopping of frame deployment/retraction. Further details regarding the control panel are described below.

[0108] In some embodiments, when a user presses a button, the control panel sends a frame deployment/retraction command to the first controller 52. The first controller 52 then controls the first motor 51 to rotate forward or in reverse. When the first motor 51 rotates in reverse, the pull rope 29 is retracted, causing the umbrella frame 54 to deploy. When the first motor 51 rotates forward, the pull rope 29 is released, allowing the umbrella frame 54 to retract under gravity.

[0109] In some embodiments, the first controller 52 may further integrate a wireless communication module to establish a connection with a smart terminal of the user via Bluetooth or Wi-Fi, so that the user can remotely send frame deployment/retraction commands through the smart terminal to control the umbrella frame 54 to deploy or retract.

[0110] In some embodiments of the present disclosure, by installing the first motor and the first controller, the operational difficulty for the user in deploying/retracting the umbrella frame can be reduced, thereby enhancing the automation level of the sunshade umbrella.

[0111] In some embodiments, as shown in FIG. 7, the sunshade umbrella further includes a torque sensor 50 installed on an output shaft of the first motor 51. The torque sensor 50 is configured to monitor a motor load torque of the first motor 51 in real-time and feed back the motor load torque to the first controller 51. The first controller 52 is configured to, in response to the motor load torque exceeding a torque threshold, execute a power-off shutdown operation and drive the first motor 51 to rotate forward by a preset count of turns and maintain self-locking. In response to determining that the motor load torque does not exceed the torque threshold, the first motor 51 operates continuously at a preset power level. The preset power level may be predetermined by a technician based on empirical data or actual requirements.

[0112] The torque sensor 50 refers to a sensor configured to monitor the motor load torque on the output shaft of the first motor 51 in real time. For example, the torque sensor 50 may include a strain-gauge torque sensor, a magnetoelastic torque sensor, or the like.

[0113] The torque threshold refers to a maximum allowable motor load torque for the first motor 51. In some embodiments, the torque threshold may be preset manually based on experience or a motor type.

[0114] In some embodiments, when the motor load torque exceeds the torque threshold (e.g., when the umbrella frame 54 encounters an obstacle during deployment and cannot deploy normally), the torque sensor 50 feeds the motor load torque back to the first controller 52. The first controller 52 immediately executes the power-off shutdown operation, drives the first motor 51 to rotate forward by the preset count of turns, releases a portion of the pull rope 29 via the rope reel 10, and then maintains self-locking.

[0115] The preset count of turns refers to a predetermined rotation count of the first motor 51, such as 1 turn, 2 turns, etc.

[0116] In some embodiments, by configuring the torque sensor 50 to monitor the motor load torque of the first motor 51 in real time, damages caused by over-driving the rope reel 10 can be prevented. For example, scenarios where the first motor 51 and the crank 32 simultaneously drive the rope reel 10, or where improper frame deployment/retraction commands are input by the user can be avoided.

[0117] In some embodiments, as shown in FIG. 5, the sunshade umbrella further includes a locking device 49 and a second motor 67. The locking device 49 is disposed between the latch bar 21 and the hand-press portion 18 and is drivingly connected to the latch bar 21. The second motor 67 is disposed inside the handle 4, and an output shaft of the second motor connected to the movable wheel 16. A second controller 68 (see FIG. 10) is disposed inside the base 3 and electrically connected to the locking device 49 and the second motor 67.

[0118] The locking device 49 refers to a device for controlling the engagement or disengagement between the latch bar 21 and the upper threaded hole 12. For example, the locking device 49 may include a micro motor, an electromagnetic actuator, or the like.

[0119] In some embodiments, the locking device 49 may be disposed between the latch bar 21 and the hand-press portion 18 and drivingly connected to the latch bar 21 via a gear. When the hand-press portion 18 is released, the locking device 49 rotates forward, driving the gear to push the latch bar 21 into engagement with the upper threaded hole 12. Conversely, when the hand-press portion 18 is pressed, the locking device 49 rotates in reverse, pulling the latch bar 21 away from the upper threaded hole 12.

[0120] The second motor 67 refers to a motor installed inside the handle 4, such as a linear motor, a screw-driven mechanism, or the like. In some embodiments, the output shaft of the second motor 67 is drivingly connected to the movable wheel 16, driving the rotation of the movable wheel 16 and thereby moving the handle 4 along the upper vertical rod 7.

[0121] The second controller 68 refers to a control module for controlling the operation of the second motor 67. In some embodiments, the second controller 68 may receive a command from the control panel and adjust an operating state of the second motor 67 to drive the handle 4 to move along the upper vertical rod 7, thereby achieving automated adjustment of a canopy tilt angle. Further details regarding the second controller are provided below.

[0122] The canopy tilt angle refers to an angle between the canopy and a horizontal plane. For a curved canopy, the canopy tilt angle may be defined as an angle between a tangent line of the generatrix of the canopy at an outer edge of the canopy and the horizontal plane. For a pyramidal canopy or a prismoidal canopy, the canopy tilt angle may be an angle between a side surface of the canopy and the horizontal plane. For a conical canopy or a frustum-shaped canopy, the canopy tilt angle may be an angle between the generatrix of the canopy and the horizontal plane. In some embodiments, the canopy tilt angle may be measured using an inclination sensor (e.g., a level meter, inclinometer, etc.).

[0123] In some embodiments, the second controller 68 is configured to, in response to receiving a tilt adjustment command acquired by the control panel, sequentially execute: driving the locking device 49 to release a connection between the latch bar 21 and the umbrella pole 53; activating the second motor 67 to drive the handle to move in an axial direction to adjust the canopy tilt angle to a target angle; and in response to the canopy tilt angle reaching the target angle, driving the locking device 49 to reset and complete locking.

[0124] In some embodiments, the control panel further includes a tilt adjustment button for receiving the tilt adjustment command input by the user.

[0125] In some embodiments, the control panel sends the tilt adjustment command to the second controller 68, which then: controls the locking device 49 to disengage the latch bar 21 from the upper threaded hole 12, releasing the connection between the latch bar 21 and the umbrella pole 53; activates the second motor 67 to drive the handle 4 to move along the axial direction of the upper vertical rod 7 to adjust the canopy tilt angle to the target angle; and controls the locking device 49 to re-engage the latch bar 21 with the upper threaded hole 12 to secure the position of the handle 4.

[0126] The target tilt angle refers to a predetermined canopy tilt angle. In some embodiments, the target tilt angle may be set according to user requirements and practical usage conditions.

[0127] In some embodiments of the present disclosure, by using the second controller to regulate the operating state of the second motor and the locking device driven by the second motor, the effort required for the user to move the handle can be reduced, a closed-loop adjustment of the umbrella's configuration can be achieved, and continuous and automated canopy tilt angle adjustment can be ensured.

[0128] In some embodiments, the sunshade umbrella further includes a processor 69 disposed inside the base 3 and electrically connected to the first controller 52 and the second controller 68. The processor is configured to: store historical operation data and extract a parameter combination including a pole height, a frame deployment degree, and the canopy tilt angle; and automatically generate a control instruction set containing the parameter combination during deployment of the umbrella frame, and send the instruction set to a corresponding controller to execute umbrella morphology initialization.

[0129] The pole height refers to a vertical distance from an end of the lower vertical rod 6 adjacent to the base 3 to the closure cap 15 along the umbrella pole 53. In some embodiments, the pole height may be acquired in real-time using a displacement sensor (e.g., a laser displacement sensor), which may be mounted on the closure cap 15 or other feasible locations.

[0130] The frame deployment degree refers to an extent of expansion of the umbrella frame 54. In some embodiments, the frame deployment degree may be represented as a range of 0-90, where 90corresponds to full deployment of the umbrella frame 54 and 0indicates complete retraction of the umbrella frame 54.

[0131] The parameter combination represents aggregated operational parameters extracted from historical data for umbrella morphology initialization. In some embodiments, the processor 69 filters out erroneous operations and outliers from stored historical operation data, then statistically identifies a pole height, a frame deployment degree, and a canopy tilt angle whose occurrence exceed a preset count threshold as the parameter combination. The preset count threshold may be empirically determined.

[0132] More descriptions regarding how to determine the parameter combination may be found in related descriptions below.

[0133] The historical operation data refers to data recorded during users'historical operations. In some embodiments, the historical operation data includes a historical pole height, a historical frame deployment degree, a historical canopy tilt angle, a historical operation time, etc.

[0134] The control instruction set refers to a collection of commands for controlling the corresponding controller to execute the umbrella morphology initialization. For example, the control instruction set may include one or more of a frame deployment/retraction command, a frame deployment degree command, a canopy tilt adjustment command, or the like In some embodiments, the processor 69 automatically generates the control instruction set containing the parameter combination through a predefined algorithm. The algorithm may be preconfigured by technical personnel.

[0135] In some embodiments, the processor 69 may acquire a control instruction set transmitted from a remote processor (e.g., a user's smart terminal or a cloud server) via Bluetooth or Internet protocols, and send the control instruction set to the processor or the corresponding controller.

[0136] The umbrella morphology refers to a posture of the sunshade umbrella. For example, the umbrella morphology includes the pole height, the frame deployment degree, the canopy tilt angle, etc. The umbrella morphology initialization refers to an operation establishing an initial posture of the sunshade umbrella. User operations may be reduced through the umbrella morphology initialization.

[0137] In some embodiments, the processor 69 may extract parameter combinations from stored historical operation data, automatically generate corresponding control instruction sets for the parameter combinations, transmit a frame deployment degree command to the first controller 52 and a tilt adjustment command to the second controller 68, thereby completing umbrella configuration initialization without requiring repetitive user adjustments.

[0138] In some embodiments of the present disclosure, the processor generates the control instruction set that bundles the multi-dimensional parameter combination for transmission, thereby reducing latency and improving response speed. In addition, user profiles can be establish based on the historical operation data to enhance user experience and convenience.

[0139] In some embodiments, the sunshade umbrella further includes a wind speed sensor electrically connected to the processor 69. The wind speed sensor is configured to acquire real-time wind speed data, and the processor is further configured to determine the parameter combination of the pole height, the frame deployment degree, and the canopy tilt angle based on the real-time wind speed data.

[0140] The wind speed sensor refers to a sensor for real-time monitoring of wind speed and volume. For example, the wind speed sensor may include a cup anemometer, a propeller anemometer, or the like.

[0141] In some embodiments, the processor 69 may determine the parameter combination of the pole height, the frame deployment degree, and the canopy tilt angle by querying a first preset table based on the real-time wind speed data. The first preset table contains correspondence relationships between multiple sets of real-time wind speed data and parameter combinations of pole heights, frame deployment degrees, and canopy tilt angles. In some embodiments, the first preset table may be constructed based on historical data.

[0142] In some embodiments, in response to the real-time wind speed data acquired by the wind speed sensor exceeding a wind speed threshold, the processor 69 may determine the parameter combination by querying the first preset table based on the real-time wind speed data; generate a frame deployment/retraction command and transmit the frame deployment/retraction command to the first controller 52. In response to receiving the frame deployment/retraction command, the first controller 52 drives the first motor 51 to rotate and fully retract the umbrella frame 54. Simultaneously, the processor 69 transmits an alert notification to the user's smart terminal to warn the user to stay clear of the sunshade umbrella.

[0143] In some embodiments, in response to the real-time wind speed data acquired by the wind speed sensor does not exceed the wind speed threshold, the processor 69 may determine the parameter combination by querying the first preset table based on the real-time wind speed data; and automatically generate a control instruction set containing the parameter combination through a preset program, and transmit the control instruction set to the corresponding controller, thereby enabling real-time adjustment of the umbrella morphology.

[0144] The wind speed threshold refers to a predetermined limit value for wind speed. In some embodiments, the wind speed threshold may be set empirically. It should be noted that when the real-time wind speed data exceeds the wind speed threshold, the sunshade umbrella faces potential toppling risks due to excessive wind forces.

[0145] Some embodiments of the present disclosure enhance user safety during sunshade operation by providing the wind speed sensor to acquire the real-time wind speed data and automatically adjusting the umbrella morphology accordingly.

[0146] In some embodiments, the processor 69 is further connected to a light sensor positioned beneath the umbrella frame 54 and configured to acquire real-time lighting data. The processor 69 is further configured to determine a deployment degree increment value in response the real-time lighting data exceeding a light intensity threshold; generate a deployment degree adjustment command based on the deployment degree increment value; and transmit the deployment degree adjustment command to the first controller 52 to control the first motor 51 to adjust the frame deployment degree.

[0147] The light sensor refers to a device for monitoring the lighting data in real time, such as a photoelectric sensor, or the like.

[0148] The real-time lighting data reflects current lighting or illumination conditions. For example, the real-time lighting data may include a real-time light intensity, a real-time ultraviolet (UV) intensity, or the like. In some embodiments, the processor 69 may obtain the real-time lighting data by querying third-party software. For example, the real-time lighting data may be acquired through a weather app on the user's smart terminal.

[0149] In some embodiments, the light intensity threshold may be empirically predetermined.

[0150] The deployment degree increment value refers to an increased value of the degree of deployment of the umbrella frame. The deployment degree increment value may be expressed as a percentage, such as 10%. In some embodiments, the deployment degree increment value may be expressed in degrees, such as 0to 90. In some embodiments, the deployment degree increment value is positively correlated with the real-time lighting data. The greater the real-time lighting data is, the larger the deployment degree increment value is.

[0151] The deployment degree adjustment command refers to an instruction for controlling the deployment of the umbrella frame 54. In some embodiments, the processor 69 may generate the deployment degree adjustment command by querying a second preset table based on the deployment degree increment value. The second preset table includes correspondence relationships between multiple sets of frame deployment degrees and deployment degree increment values, and corresponding deployment degree adjustment commands. For example, when the frame deployment degree is 60and the deployment degree increment value is 10, the deployment degree adjustment command may be that the first motor 51 rotates in reverse by 0.5 turns. In some embodiments, the second preset table may be constructed based on historical data.

[0152] In some embodiments, in response to receiving the deployment degree adjustment command sent by the processor 69, the first controller 52 immediately drives the first motor 51 to rotate, thereby adjusting the frame deployment degree.

[0153] In some embodiments of the present disclosure, by configuring the light sensor to acquire the real-time lighting data and automatically adjusting the frame deployment degree based on the real-time lighting data, the adjustment of the frame deployment degree can be made more reasonable, thereby improving user experience.

[0154] In some embodiments, the processor 69 is further connected to a temperature sensor configured to acquire real-time temperature data. The processor 69 periodically executes the following operations determining a target tilt angle based on both real-time lighting data and the real-time temperature data; generating a tilt adjustment command based on the target tilt angle; and transmitting the tilt adjustment command to the second controller 68 to drive the second motor 67 to adjust the canopy tilt angle to the target tilt angle.

[0155] The temperature sensor refers to a device for real-time environmental temperature monitoring, including but not limited to a thermometer, a radiation thermometer, or the like

[0156] In some embodiments, the processor 69 may acquire the real-time temperature data through a third-party application (e.g., a weather app on the smart device of the user).

[0157] The tilt adjustment command refers to an instruction for controlling an inclination angle of a surface of the canopy. In some embodiments, the processor 69 may determine the target tilt angle and generate the tilt adjustment command by querying a third preset table based on the real-time lighting data and the real-time temperature data. The third preset table contains correspondence relationships between multiple sets of real-time lighting data, real-time temperature data, target tilt angles, and corresponding tilt adjustment commands. In some embodiments, the third preset table may be constructed based on historical data. More descriptions regarding the target tilt angle may be found in relevant descriptions provided above.

[0158] In some embodiments, in response to receiving the tilt adjustment command sent by the processor 69, the second controller 68 immediately drives the second motor 67 to rotate, thereby adjusting the canopy tilt angle to the target value.

[0159] It should be noted that an execution period for the processor 69 to perform the aforementioned operations may be configured according to actual usage scenarios and user requirements. For example, the execution period may be set to one hour.

[0160] In some embodiments of the present disclosure, by configuring the temperature sensor to acquire the real-time temperature data and adjusting the canopy tilt angle based on a combination of the real-time temperature data and the real-time light intensity data, the canopy tilt angle can be determined and adjusted more reasonably, thereby further improving user experience.

[0161] FIG. 8 is a schematic structural diagram of lower umbrella rods, upper umbrella rods, a middle rod head, a lower rod head, and an upper rod head according to some embodiments of the present disclosure.

[0162] In some embodiments, as shown in FIG. 8, the middle rod head 27 is provided with the lower umbrella rods 1 and the second inclined rod 23. The lower rod head 30 is disposed below the middle rod head 27, and an upper rod head 33 is disposed above the middle rod head 27. The middle rod head, the lower rod head, and the upper rod head are disposed on the round rod 34. The lower rod head 30 is provided with a connecting rod 35 that connects the lower rod head 30 and the second inclined rod 23. The lower umbrella rods 1 are provided with one or more illumination lamp 36.

[0163] In some embodiments, as shown in FIG. 8, a plurality of illumination lamps 36 (e.g., four illumination lamps 36 per rib) may be equidistantly installed on a plurality of lower umbrella rods 1. The illumination lamps 36 may be connected to the lower umbrella rods 1 through screw fixation, recessed embedding, or the like.

[0164] In some embodiments, a portion of the pull rope 29 is located inside the round rod 34, thereby protecting the pull rope 29 through the round rod 34. The connecting rod 35 ensures a stable connection between the lower rod head 30 and the second inclined rod 23. The illumination lamp(s) 36 facilitate the use of the sunshade umbrella in dark environments.

[0165] FIG. 9 is an enlarged view of section A in FIG. 1. FIG. 10 is a schematic structural diagram of a base, a rotating gear, and a foot pedal according to some embodiments of the present disclosure.

[0166] In some embodiments, as shown in FIGS. 9-10, one or more support bars 37 are disposed at a bottom portion of the base 3. The base 3 is connected to the one or more support bars 37 via one or more first screws 38. A protruding portion 39 is disposed on the base 3 and connected to a rotating gear 40. A seat plate 41 is disposed on the rotating gear 40. The seat plate 41 is fixedly connected to the upper vertical rod 7 and the lower vertical rod 6, and connected to the base 3 via one or more second screws 42.

[0167] A support bar 37 refer to a bar-shaped component located at the bottom portion of the base 3. In some embodiments, connecting the base 3 to the one or more support bars 37 via the one or more first screws 38 increases a contact area between the base 3 and the ground, thereby enhancing the stability of the sunshade umbrella when placed and reducing the risk of tipping.

[0168] It should be noted that the connection between the base 3 and the support bar(s) 37, as well as the connection between the seat plate 41 and the base 3, may also employ snap-fit connections, adhesive bonding, or the like. For example, corresponding grooves and protrusions may be provided on the contact surface between the base 3 and the support bars 37 and the contact surface between the seat plate 41 and the base 3, to achieve a snap-fit connection through the engagement of the protrusions and the grooves.

[0169] The protruding portion 39 refers to a columnar or shaft-like protrusion structure located at a central upper surface of the base 3. In some embodiments, the rotating gear 40 may be sleeved over the protruding portion 39 and rotate about an axis of the protruding portion 39.

[0170] In some embodiments, the base 3 is fixedly connected to the support bar(s) 37 via the first screw(s) 38. The protruding portion 39 is connected to the rotating gear 40, enabling the rotating gear 40 to rotate along the protruding portion 39. The second screw(s) 42 ensure a stable connection between the seat plate 41 and the base 3. The upper vertical rod 7 and the lower vertical rod 6 are fixedly connected to the base 3, thereby facilitating the rotation of the base 3 and the seat plate 41 driven by the upper vertical rod 7 and the lower vertical rod 6.

[0171] In some embodiments, as shown in FIG. 10, a rotation-limiting portion 43 is disposed on a side of the base 3. The rotation-limiting portion 43 is provided with a locking block 44 located between teeth of the rotating gear. A foot pedal 45 is disposed on the rotation-limiting portion 43, and a second spring 46 is installed inside the rotation-limiting portion 43. A protective cover 47 is disposed above the rotating gear 40.

[0172] The rotation-limiting portion 43 refers to a component disposed on a side of the base 3 and capable of moving vertically relative to the base 3. In some embodiments, the rotation-limiting portion 43 may be used to lock the rotating gear 40.

[0173] The second spring 46 refers to an elastic component disposed within the rotation-limiting portion 43. In some embodiments, when the foot pedal 45 is depressed downward, the second spring 46 compresses, causing the locking block 44 to disengage from the teeth of the rotating gear 40. When the pedal portion 45 is not depressed, the second spring 46 remains in an extended state, pushing the locking block 44 toward the rotating gear 40 such that the locking block 44 engages between the teeth of the rotating gear 40 to achieve locking of the rotating gear 40.

[0174] In some embodiments, the protective cover 47 is disposed above the rotating gear 40 to prevent dust and debris from entering a gear engagement zone to improve operational safety.

[0175] In some embodiments, when it is necessary to rotate the canopy of the sunshade umbrella, the foot pedal 45 may be stepped on to disengage the locking block 44 from the teeth of the rotating gear 40. Then, the upper vertical rod 7 and the lower vertical rod 6 may be rotated to adjust the position of the canopy. After the adjustment is completed, releasing the foot from the foot pedal 45 allows the locking block 44 to be positioned between the gear teeth, thereby restricting the rotation of the rotating gear 40. When the foot pedal 45 is not being stepped on, the second spring 46 prevents the locking block 44 from disengaging from the teeth of the rotating gear 40.

[0176] Some embodiments of the present disclosure enable foot-operated release of the locking block 44 from the rotating gear 40, permitting rotation of the upper vertical rod 7 and lower vertical rod 6 to adjust the position of the canopy. This mechanism provides convenient and labor-saving operation.

[0177] FIG. 11 is a cross-sectional view of a sunshade umbrella according to some other embodiments of the present disclosure.

[0178] In some embodiments, as shown in FIG. 11, the handle 4 is slidably installed on an inner side of the umbrella pole 53. The handle 4 is capable of locking at a target position on the umbrella pole 53. The handle 4 is pivotally connected to the second inclined rod 23, and the second inclined rod 23 is fixed to the umbrella frame 54. A middle portion of the second inclined rod 23 is pivotally connected to the first inclined rod 22, an end of the first inclined rod 22 is pivotally connected to a top portion of the umbrella pole 53. The hand-crank portion 9 is installed at a middle portion of the umbrella pole 53, the pull rope 29 is wound around the hand-crank portion 9 and configured to drive the umbrella frame 54 to deploy or retract. The pull rope 29 sequentially passes through the umbrella pole 53, the first inclined rod 22, and the second inclined rod 23, and finally connects to a bottom end of the umbrella frame 54.

[0179] In some embodiments, the inner side of the umbrella pole 53 is provided with a longitudinal adjustment channel having multiple holes, and a sliding member and a locking components are installed on two sides of the handle 4. The handle 4 is slidably installed on the umbrella pole 53 via the sliding member sliding within the longitudinal adjustment channel. The handle 4 may be locked at a target position on the umbrella pole 53 by engaging the locking component into any one of the holes of the longitudinal adjustment channel. More descriptions regarding how the handle 4 can be locked at any target position on the umbrella pole 53, please refer to FIG. 16 and the related description.

[0180] In some embodiments, shaft holes are respectively provided at an end of the second inclined rod 23 near the handle 4, the middle portion of the second inclined rod 23, the handle 4, and connecting ends of the first inclined rod 22 and the second inclined rod 23 wherein the first inclined rod 22 and the second inclined rod 23 are mutually connected. Pins are inserted through the shaft holes to connect the second inclined rod 23 to the handle 4, and the second inclined rod 23 to the first inclined rod 22, so that the second inclined rod 23 is able to rotate about the handle 4 and also rotate with the first inclined rod 22, thereby allowing flexible adjustment of the canopy tilt angle.

[0181] In some embodiments, the second inclined rod 23 may be fixedly connected to the umbrella frame 54 through a plug-in connection, etc., allowing the umbrella frame 54 to rotate with the second inclined rod 23 to adjust the canopy tilt angle.

[0182] In some embodiments, an end of the first inclined rod 22 near the umbrella pole 53 may also be pivotally connected to the top portion of the umbrella pole 53, allowing the first inclined rod 22 to rotate about the top portion of the umbrella pole 53.

[0183] In some embodiments, the first inclined rod 22 and the second inclined rod 23 form a triangular support structure, which enhances a wind resistance capability of the umbrella frame 54.

[0184] In some embodiments of the present disclosure, the routing path of the pull rope 29 is arranged to avoid the handle 4, allowing the handle 4 to be positioned on the side of the upper vertical rod 7 near the center of gravity of the umbrella frame 54. This arrangement reduces the sliding resistance of the handle 4 and makes it easier for the user to move the handle 4 with less effort, thereby facilitating more convenient adjustment of the canopy tilt angle.

[0185] In some embodiments, each of the umbrella pole, the first inclined rod, and the second inclined rod has a hollow interior, and a sixth pulley is rotatably installed in the hollow interior of each of the umbrella pole, the first inclined rod, and the second inclined rod.

[0186] The sixth pulley 55 refers to a fixed pulley installed inside the umbrella pole 53, the first inclined rod 22, and the second inclined rod 23. In some embodiments, a plurality of sixth pulleys 55 may be respectively installed at: an upper end of the umbrella pole 53, two ends of the first inclined rod 22, the middle portion of the second inclined rod 23, and a top portion of the second inclined rod 23. The middle portion of the second inclined rod 23 is provided with a through-hole for the pull rope 29, which sequentially passes through the plurality of sixth pulleys 55.

[0187] It should be understood that each of the umbrella pole 53 (e.g., the upper vertical rod 7), first inclined rod 22, and second inclined rod 23 all has a hollow interior. This design not only accommodates the sixth pulleys 55 but also allows passage of the pull rope 29.

[0188] In some embodiments, as shown in FIG. 11, the umbrella frame 54 includes an upper canopy hub 56, a lower canopy hub 57, and a plurality of rib structures cooperatively arranged on upper canopy hub 56 and the lower canopy hub 57. The upper canopy hub 56 is fixedly connected to the second inclined rod 23, and an end of the pull rope 29 is connected to the lower canopy hub 57. When the hand-crank portion 9 retracts the pull rope 29, the lower canopy hub 57 moves upward toward the upper canopy hub 56 to drive the umbrella frame 54 to deploy. When the hand-crank portion 9 releases the pull rope 29, the lower canopy hub 57 moves downward away from the upper canopy hub 56 to drive the umbrella frame 54 to retract.

[0189] The upper canopy hub 56 and lower canopy hub 57 are disc-shaped components for connecting and driving the rib structures. In some embodiments, the upper canopy hub 56 is connected to the second inclined rod 23 and serves as an upper fixation point for the rib structures. In some embodiments, the lower canopy hub 57 is connected to an end of the pull rope 29, enabling vertical movement through the retraction/release of the pull rope 29.

[0190] In some embodiments, the plurality of rib structures may include a plurality of upper ribs 2 and a plurality of lower ribs 1.

[0191] In some embodiments, a limit protrusion 65 may be provided at a bottom portion of the lower rod head 30. The pull rope 29 sequentially passes through the first pulley 13, the second pulley 14, the third pulley 25, the fourth pulley 26, and the fifth pulley 28, and finally connects to the limit protrusion 65. When the rib structures are fully deployed, the limit protrusion 65 engages with the upper canopy hub 57, and an end of the pull rope 29 is fixedly connected to the limit protrusion 65.

[0192] In some embodiments, as shown in FIG. 11, a self-locking ratchet mechanism 66 may be disposed inside the hand-crank portion 9 to maintain tension control of the pull rope 29 during deployment and retraction. When the pull rope 29 is retracted to deploy the umbrella frame 54, the crank 32 is rotated to gradually retract the pull rope 29 via the self-locking ratchet mechanism 66. After the umbrella frame 54 is fully deployed, the self-locking ratchet mechanism 66 automatically locks to prevent the pull rope 29 from rebounding, thereby ensuring that the umbrella frame 54 remains open under wind force. When the pull rope 29 is released to retract the umbrella frame 54, a ratchet release button on the self-locking ratchet mechanism 66 may be gently pressed to disengage the locking of the pull rope 29.

[0193] The self-locking ratchet mechanism 66 refers to an assembly that achieves unidirectional locking through coordinated interaction between ratchet wheels and pawls.

[0194] FIG. 12 is a schematic structural diagram of an umbrella pole according to some other embodiments of the present disclosure. FIG. 13 is a cross-sectional view of the umbrella pole according to some other embodiments of the present disclosure. FIG. 14 is a schematic structural diagram of a handle according to some other embodiments of the present disclosure. FIG. 15 is an assembly schematic diagram of the umbrella pole and an umbrella frame according to some other embodiments of the present disclosure. FIG. 16 is an enlarged view of section B in FIG. 12.

[0195] In some embodiments, as shown in FIGS. 12-16, an end of the umbrella pole 53 is provided with an adjustment slot 58 that is vertically arranged, and an end of the handle 4 is embedded within and slidable along the adjustment slot 58. Two slider sets that are symmetrically arranged are fixed to the handle 4, each of the two slider sets includes two sliders 59, and slide grooves 60 are formed on an inner sidewall of the adjustment slot 58 for embedding the sliders 59. Two roller sets that are symmetrically arranged are rotatably installed on the handle 4, each of the two roller sets includes two rollers 61. Each of the two slider sets is positioned between the two rollers 61 of a corresponding roller set, and the rollers 61 are embedded within the slide grooves 60.

[0196] The adjustment slot 58 refers to an elongated groove vertically formed along a side of the umbrella pole 53. In some embodiments, a width of the adjustment slot 58 is greater than a width of the handle 4. In some embodiments, the adjustment slot 58 provides a guiding channel for a vertical movement of the handle 4. In some embodiments, an end of the handle 4 is embedded within the adjustment slot 58, thereby establishing a sliding connection with the upper vertical rod 7.

[0197] In some embodiments, the two symmetrically arranged slider sets fixed to the handle 4 may be understood as that the slider sets fixed to the handle 4 are symmetric about a vertical central axis of the handle 4. In other words, the two slider sets are fixed on opposite sides of an end of the handle 4 that is embedded in the adjustment slot 58. In some embodiments, the two sliders 59 of each slider set are positioned between two rollers 61 on the same side of the handle 4.

[0198] In some embodiments, the sliders 59 are hard, wear-resistant blocks (e.g., made of nylon) designed to be inserted into the slide grooves 60 to restrict lateral displacement of the handle 4.

[0199] A slide groove 60 refers to an elongated recess formed on the inner sidewall of the adjustment slot 58. In some embodiments, a groove profile of the slide groove 60 matches the contours of the slider 59 and roller 61, serving to accommodate the slider 59 and roller 61 while constraining their movement paths.

[0200] In some embodiments, the two symmetrically arranged roller sets rotatably installed on the handle 4 may be understood as that the roller sets rotatably installed on the handle 4 are symmetric about the vertical central axis of the handle 4. In other words, the roller sets are rotationally installed on opposite sides of the end of the handle 4 that is embedded within the adjustment slot 58.

[0201] In some embodiments, each roller 61 is a cylindrical rolling element. An outer circumference of each of the rollers 61 may be coated with rubber to reduce frictional resistance during the movement of the handle 4. The rollers 61 are embedded within the slide grooves 60 and move along the slide grooves 60 during operation.

[0202] In some embodiments, when the handle 4 is moved, it slides up and down along the adjustment slot 58 on the upper vertical rod 7. The roller sets roll within the slid grooves 60, and the slider sets simultaneously slide within the slid grooves 60, thereby reducing the resistance encountered when moving the handle 4. In addition, the slider sets can also restrict lateral displacement of the handle 4, ensuring the stability of the handle 4 during vertical movement.

[0203] In some embodiments, as shown in FIGS. 14 and 16, the handle 4 is provided with a driving member 62, which is slidably connected to the handle 4. An end of the driving member 62 is fixedly provided with a locking pin 64. A plurality of locking holes 63 are formed on an inner wall of the adjustment slot 58. An elastic reset member 70 is disposed inside the driving member 62 to drive the locking pin 64 to insert into one of the plurality of locking holes 63. When the driving member 62 is pressed, the engagement between the locking pin 64 and the locking hole 63 is released. After the handle 4 slides to a target position, the driving member 62 is released to allow the locking pin 64 to automatically lock into place under an elastic force of the elastic reset member 70. It may be understood that through the above configuration, the canopy tilt angle can be adjusted simply by pushing or pulling the handle 4, thereby accommodating different usage scenarios.

[0204] A locking hole 63 refers to a through-hole formed on the inner wall of the adjustment slot 58. In some embodiments, a shape of each of the locking holes 63 matches that of the locking pin 64, and a depth of each of the locking holes 63 is greater than a length of the locking pin 64.

[0205] The elastic reset member 70 refers to a mechanical component that generates a restoring force through elastic deformation, such as a spring, etc. In some embodiments, an end of the elastic reset member 70 is disposed inside the driving member 62, and another end of the elastic reset member 70 is fixedly connected to the locking pin 64.

[0206] In some embodiments, as shown in FIG. 16, the locking holes 63 are uniformly distributed along a length direction of the adjustment slot 58 at a spacing of 5 cm.

[0207] In some embodiments, the spacing of the locking holes 63 may also be set as needed, such as 3 cm or 10 cm. In some embodiments, the locking holes 63 may also be distributed non-uniformly along the length direction of the adjustment slot 58. For example, in commonly used height ranges (e.g., 1.2 m to 1.6 m), the spacing between any two locking holes 63 is 3 cm, while in less commonly used ranges (e.g., below 1.2 m or above 1.6 m), the spacing is 5 cm.

[0208] In some embodiments of the present disclosure, the locking holes are uniformly distributed at a preset spacing along the length direction of the adjustment slot, which simplifies the complexity of umbrella frame processing while covering the height adjustment needs of most users.

[0209] In some embodiments, a canopy deployment process of the sunshade umbrella includes steps S11-S12.

[0210] S11: a height of the handle 4 is adjusted to suit a height of a user.

[0211] S111: the handle 4 is unlocked. The driving member 62 on the handle 4 is pressed with one hand, compressing the elastic reset member 70 so that the locking pin 64 is disengaged from a current locking hole 63.

[0212] S112: the handle 4 slides to a target position. The handle 4 is slid up or down along the adjustment slot 58 on the umbrella pole 53, while the roller sets 61 roll within the slid grooves 60, and the slider sets 59 limit lateral displacement of the handle 4 to ensure stability during vertical sliding.

[0213] S113: the handle 4 is locked in place. The driving member 62 is released, allowing the elastic reset member 70 to push the locking pin 64 into the nearest locking hole 63, thereby fixing the position of the handle 4.

[0214] S12: the canopy is deployed. The pull rope 29 is retracted by the hand-crank portion 9 to deploy the canopy.

[0215] S121: the hand-crank portion is operated. The hand-crank portion 9 on the outer surface of the umbrella pole 53 is rotated forward, and the pull rope 29 is gradually retracted via the self-locking ratchet mechanism 66.

[0216] S122: the lower umbrella hub is driven upward. The pull rope 29 is guided through multiple pulleys within the umbrella pole 53, the first inclined rod 22, and the second inclined rod 23, pulling the lower umbrella hub 57 upward toward the upper umbrella hub 56.

[0217] S123: the umbrella ribs are deployed. As the lower umbrella hub 57 moves upward, the rib structures are pushed outward by force, gradually opening the canopy.

[0218] S124: the rib structures are fully deployed and locked. When all the umbrella rib structures are fully deployed, the limiting protrusion 65 at the bottom portion of the lower umbrella hub 57 engages with the upper umbrella hub 56.

[0219] S125: self-locking is maintained. The self-locking ratchet mechanism 66 automatically locks to prevent the pull rope 29 from rebounding, ensuring that the canopy remains open under wind force.

[0220] In some embodiments, a canopy retraction process of the sunshade umbrella includes steps S21-S24.

[0221] S21: the pull rope 29 is released. The hand-crank portion 9 on the outer surface of the umbrella pole 53 is rotated in reverse to release the pull rope 29.

[0222] S22: the self-locking mechanism is disengaged. The ratchet release button on the hand-crank portion 9 is gently pressed (or the hand-crank portion 9 is gently pulled outward) to disengage the locking of the pull rope 29 by the self-locking ratchet mechanism 66.

[0223] S23: the hand-crank portion 9 is rotated in reverse. The hand-crank portion 9 is slowly rotated in reverse to release the pull rope 29. The lower umbrella hub 57 naturally moves downward under its own weight and the elastic force of the umbrella rib structures.

[0224] S24: the canopy is retracted. As the lower umbrella hub 57 moves downward, the rib structures fold inward, and the canopy gradually retracts into a vertical state.

[0225] In some embodiments of the present disclosure, the handle and the hand-crank portion are arranged separately, making it suitable for users of different heights to operate the deployment and retraction of the canopy, thus offering convenient operation and broad applicability. Moreover, the umbrella pole, the second inclined rod, and the first inclined rod are hollow and internally integrated with fixed pulleys. The pull rope is guided by a plurality of fixed pulleys, and the routing path of the pull rope in the hand-crank portion avoids the handle, allowing the locking component on the handle to be positioned closer to the side of the umbrella frame. This configuration reduces the sliding resistance during the movement of the handle, making it easier for the user to move the handle with less effort and thereby facilitating canopy tilt angle adjustment.

[0226] Having thus described the basic concepts, it may be rather apparent to those skilled in the art after reading this detailed disclosure that the foregoing detailed disclosure is intended to be presented by way of example only and is not limiting.
