The upper seat and the lower seat rotate about the rotation axis, the resilient pad is provided between the upper seat and the lower seat, an upper end of the compression spring is fixedly connected to the upper seat, and a lower end of the compression spring is fixedly connected to the lower seat. More details regarding this section may be found in other contents of the present disclosure (e.g., description in connection with
[0053] In some embodiments, the elastic device may include the resilient pad, the tension spring, and the compression spring. The rocking member 100 may include the upper seat, the lower seat, the rotation axis, the resilient pad, the tension spring, and the compression spring. The upper seat and the lower seat rotate about the rotation axis, the resilient pad is provided between the upper seat and the lower seat, the tension spring is provided on a front side of the camping chair close to the seat 500, the compression spring is provided on a back side of the camping chair away from the seat 500. The upper end of the tension spring and the upper end of the compression spring are fixedly connected to the upper seat, and the lower end of the tension spring and the lower end of the compression spring are fixedly connected to the lower seat. More details regarding this section may be found in other contents of the present disclosure (e.g., description in connection with
[0054] In some embodiments, the rocking member 100 may also be realized by any other feasible means. For example, the rocking member 100 may also be a motorized component eliminating a need for manual adjustment. Exemplarily, the motorized component may include 2 motorized actuators, and the 2 motorized actuators drive the upper support member 200 towards a position near a front side of the seat 500 and away from a rear side of the seat 500, respectively, achieving different heights at the front and back of the upper support member 200, which causes the camping chair to tilt and thus rock.
[0055] In some embodiments, the two ends of the rocking member 100 are connected to the upper support member 200 and the lower support member 300.
[0056] Connection methods may be any feasible method. For example, the two ends of the rocking member 100 may be fixedly connected to the upper support member 200 and the lower support member 300, respectively. Methods of fixed connection may include, but are not limited to, welding, heat fusion, riveting connection, or the like.
[0057] In some embodiments, the two ends of the rocking member 100 may be detachably connected to the upper support member 200 and the lower support member 300, respectively. With a detachable connection, when the user needs to store the camping chair, the upper support member 200 and the lower support member 300 may be separated from the rocking member 100 to reduce the space required for storing the entire camping chair.

For example, the upper support member 200 and the rocking member 100 are interconnected, with an outer diameter of a connecting end of the upper support member 200 being slightly smaller than an inner diameter of a connecting end of the rocking member 100, and a fixation is realized by inserting the upper support member 200 into the rocking member 100. As another example, the lower support member 300 and the rocking member 100 are interconnected, with an inner diameter of a connecting end of the lower support member 300 being larger than an outer diameter of a connecting end of the rocking member 100, and a fixation is realized by inserting the rocking member 100 into the lower support member 300.
[0060] More details regarding the rocking member may be found in other contents of the present disclosure (e.g., descriptions in connection with
[0061] The upper support member 200 refers to a component that is disposed above the camping chair, connected to the seat 500, and configured to support the seat 500. In some embodiments, the upper support member 200 may be detachably connected to the seat 500. Methods of detachable connection include, but are not limited to, the sleeve connection, or the like. For example, the seat 500 is provided with a plurality of cloth cartridges at edges of the seat 500, and the upper support member 200 may be inserted into the cloth cartridges to realize the sleeve connection with the seat 500.
[0062] In some embodiments, the upper support member 200 includes several first pipe fittings.
[0063] The first pipe fittings refer to components that connect the rocking member to the seat. In some embodiments, one end of each first pipe fitting is connected to the rocking member, and the other end of the each first pipe fitting is connected to the seat.
[0064] In some embodiments, a number of the first pipe fittings may be multiple. For example, three, four, or more. Exemplarily, when the number of the first pipe fittings is four, two first pipe fittings closer to the front side of the seat are short, and two first pipe fittings away from the back side of the seat are long, which allows the seat to conform to the hips and lumbar area or the back of the body. The first pipe fittings may be in a plurality of shapes, such as a round tube, a square tube, a triangular tube, or a polygonal tube. Material of the first pipe fittings may be a lightweight but strong material, such as carbon fiber, aluminum alloy, titanium alloy, and magnesium alloy, none of which are limited herein.
[0065] More details regarding the first pipe fittings may be found in other contents of the present disclosure (e.g., descriptions in connection with
[0066] The lower support member 300 refers to a component that is located underneath the camping chair, in contact with the ground, and configured to support the seat 500 and the upper support member 200. In some embodiments, the lower support member 300 includes several second pipe fittings.
[0067] The second pipe fittings refer to components that connect the rocking member and are in contact with the ground. In some embodiments, one end of each second pipe fitting is connected to the rocking member, and the other end of the each second pipe fitting is in contact with the ground.
[0068] In some embodiments, a number of the second pipe fittings may be multiple. For example, three, four, or more. In some embodiments, lengths of the several second pipe fittings meet the same height from the ground when the camping chair is unfolded. The each second pipe fitting may be in a plurality of shapes, such as the round tube, the square tube, the triangular tube, or the polygonal tube. Material of the second pipe fitting may be a lightweight but strong material, such as the carbon fiber, the aluminum alloy, the titanium alloy, and the magnesium alloy, none of which are limited herein.

[0070]
[0071] In some embodiments, as shown in
[0072] In some embodiments, folding of the camping chair may include separation of the seat 500 from the upper support member 200 or folding of the seat 500, folding of the upper support member 200 and the rocking member 100, and folding of the rocking member 100 and the lower support member 300.
[0073] The separation of the seat 500 from the upper support member 200 may be realized based on a detachable connection between the seat 500 and the upper support member 200, and the folding of the seat 500 may be realized based on a material property of the seat. For example, if the seat is made of soft material (e.g., cloth), the seat may be folded freely without separating from the upper support member. If the seat is made of hard material (e.g., alloy), the seat may not be folded freely, and the seat needs to be separated from the upper support member and then stored.
[0074] In some embodiments, the folding of the upper support member 200 and the lower support member 300 with the rocking member 100 may be realized by a plurality of ways. For example, elastic cords may also be provided between two ends of the rocking member 100 and the upper support member 200 and the lower support member 300, and the upper support member 200 and the lower support member 300 may be removed by elongation or tension of the elastic cords. Exemplarily, one end of the elastic cord is connected to the upper support member 200, and the other end of the elastic cord is connected to the rocking member 100, and when the camping chair need to be folded, after the upper support member 200 is unfastened, the upper support member 200 is pulled by the elastic cord, and not completely detached from the rocking member 100, which makes the camping chair be folded and stored at will.
[0075] As another example, other collapsible connecting components, such as non-elastic cords, may be provided between the two ends of the rocking member 100 and the upper support member 200 and the lower support member 300. Lengths of the non-elastic cords may be adjustable, with different lengths corresponding to an unfolded state or the folded state of the camping chair. Exemplarily, when the camping chair is in the folded state, the lengths of the non-elastic cords are long, at which time the upper support member 200 is not fixed to the rocking member 100, and the camping chair may be folded at will. When the camping chair needs to be unfolded, the lengths of the non-elastic cords are shortened, so that a distance between the upper support member 200 and the rocking member 100 is shortened, and at this time, the upper support member 200 is fixed to the rocking member 100, and the folding is completed. Shortening of the length may be realized by tying a knot at an end of the non-elastic cord, having a spring buckle at the end that may adjust the length, or the like.
[0076] In some embodiments, the camping chair may rotate 360 degrees. For example, the upper support member 200 may rotate three hundred and sixty degrees relative to the lower support member 300. Exemplarily, an upper portion and a lower portion of the rocking member 100 are rotationally connected. For example, the upper portion is a swivel shaft and the lower portion is a sleeve, and the swivel shaft and the sleeve are rotatable. As another example, the upper portion and the lower portion are provided with a bearing between thereof, and the upper portion is rotatable relative to the lower portion. Position of rotational connection may also be provided at any other feasible position, such as between the upper support member 200 and the rocking member 100, and between the lower support member 300 and the rocking member 100.
[0077] In some embodiments of the present disclosure, by providing the camping chair including the rocking member, the upper support member, the lower support member, and the seat, the interrelationships among the components enable the camping chair to provide the user with a supportive ability and a rocking ability, so that the user can relax and have a good experience when using the camping chair.

Exemplarily, when the sleeve connection is used, the extension tube 203 has a small outer diameter at the end near the upper tube 201, which may be inserted into the upper tube 201 and fixedly connected to the upper tube 201.
[0105] In some embodiments, a relative position of the upper tube 201 and the extension tube 203 may be adjusted.
[0106] In some embodiments, the relative position may be adjusted in a plurality of ways. For example, marbles are provided on the extension tube, and holes corresponding to the marbles are provided on the upper tube. The restriction of the position is realized by the marbles being jammed into the holes, and a plurality of holes corresponds to a plurality of relative positions. The relative positions may be adjusted by the change of the positions of the marbles into the holes. As another example, the extension tube is threadedly connected to the upper tube, and the relative position is adjusted by adjusting the length of a threaded connection portion.
[0107] In some embodiments of the present disclosure, by adjusting the relative positions of the upper tube and the extension tube, the seat can be adjusted to obtain different tautness degrees, which conforms to the needs of different people in using the seat. For example, when adjusting the relative positions of the upper tube and the extension tube so that the overall length of the first pipe fittings is short, a cloth seat is looser, and vice versa, the cloth seat is tensed.
[0108] The pipe plug 204 refers to a component configured to seal an end of the upper tube, and the use of the pipe plug prevents the entry of foreign matter, or dust, or other things into the upper tube. The connection method of the pipe plug to the upper tube may include a detachable connection, or the like, which will not be discussed herein.
[0109] In some embodiments, the second pipe fitting further includes the foot pad, which is connected to the foot tube.
[0110] The foot pad refers to a component configured to seal one end of the foot tube, and the use of the foot pad avoids the entry of foreign matter or dust or other things into the foot tube, fine-tunes a height of the camping chair, and realizes shock absorption and noise reduction. In some embodiments, there are various ways to realize the foregoing effect. For example, the foot pad is threaded to the foot tube, and the height of the camping chair is adjusted by adjusting a position of the thread. As another example, the foot pad is an elastic snap that snaps into the foot tube, and a plurality of positions of the snaps correspond to a plurality of fine-tuned heights of the camping chair. As another example, a material of the foot pad may be an elastic material, such as rubber, which enables shock absorption and noise reduction when the camping chair rocks back and forth.
[0111] In some embodiments, the length of the first pipe fittings and the length of the second pipe fittings are adjustable. The first pipe fitting of the upper support member may also include the upper tube and the extension tube, with one end of the extension tube being connected to the upper tube and the other end of the extension tube being connected to the rocking member. The second pipe fitting of the lower support member may further include the foot tube and the extension tube, with one end of the extension tube being connected to the foot tube and the other end of the extension tube being connected to the rocking member.
[0112] In some embodiments, at least one of the length or a number (or count) of the first pipe fittings and a number (or count) of the second pipe fittings may be flexibly adjusted based on actual needs of the users.
[0113] A length adjustment of pipe fittings may be realized in a plurality of ways. Taking the first pipe fitting as an example, the length of the first pipe fitting may be adjusted in a plurality of ways, such as by changing the relative position of the upper tube and the extension tube, by increasing or decreasing a number (or count) of the extension tubes to be used, by changing the length of the upper tube, or the like. Changing the length of the upper tube may be realized by replacing the upper tube with a different length or using a deformable bend as the upper tube, or the like. The adjustment of the number of pipe fittings may be realized in a plurality of ways. For example, increasing or decreasing the number of the extension tubes to be used, or the like.
[0114] The actual needs of the users may include a need for the height of the camping chair of the users. The existence of the user need to adjust a great height of the camping chair may be realized by increasing at least one of the length or the number of the first pipe fittings and the number of the second pipe fittings. The existence of the user need to adjust a low height of the camping chair may be realized by decreasing at least one of the length or the number of the first pipe fittings or the number of the second pipe fittings.
[0115] In some embodiments of the present disclosure, flexibly adjusting at least one of the length or the number of the first pipe fittings and the number of the second pipe fittings, bases on the actual needs of the users, can make the height of the camping chair more in line with the actual needs of the users.
[0116] In some embodiments of the present disclosure, the upper tube of the upper support member is detachably connected to an upper portion of the rocking member, and the foot tube of the lower support member is detachably connected to a lower portion of the rocking member, which is convenient for storage. The upper tube and the foot tube can also be connected to the rocking member by the elastic cord, which is convenient for storage and installation; and the upper support member can be provided with the extension tube, which reduces a volume after storing and makes it convenient to carry. At least one of the length or the number of pipe fittings can be adjusted, which can flexibly adjust the height of the camping chair for users with different heights or different needs to improve the scope of application of the camping chair.
[0117] In some embodiments, one or more of the upper tube, the foot tube, and the extension tube may be a plastic pipe fitting with reinforcing ribs or a plastic inner pipe internally sheathed with reinforcing ribs. The plastic inner pipe with reinforcing ribs is disposed between the upper tube and the first elastic cord, between the foot tube and the second elastic cord, or between the extension tube and the first elastic cord.
[0118] In some embodiments, taking the upper tube as an example, the first pipe fitting further includes the reinforcing rib 205, the reinforcing rib 205 being disposed between the upper tube 201 and the first elastic cord 202, as shown in
[0119] The reinforcing rib 205 refers to a component that adds strength and rigidity to the tubing. For example, the upper tube 201 is a thin aluminum alloy tube or a thin plastic tube, and the strength of the upper tube may be increased by providing the reinforcing rib 205 without additional weight.
[0120] In some embodiments, the reinforcing rib 205 may include a plurality of shapes. For example, mesh (e.g., axial, circumferential staggering), or the like, to achieve increased strength while reducing material.
[0121] In some embodiments of the present disclosure, by setting the pipe fittings to be the plastic pipe fittings with reinforcing ribs or the plastic inner pipes sheathed with reinforcing ribs, the pipe fittings can be made lighter. An outer side being a smooth pipe fitting is convenient to clean the pipe fitting. At the same time, the inner side with the reinforcing ribs can increase the strength of the pipe fittings, so that the pipe fittings can have a great resistance to pressure, thus making the camping chair widely applicable.
[0122]
[0123] In some embodiments, as shown in
[0124] The upper seat 101 refers to an upper half of the rocking member. The lower seat 102 refers to a lower half of the rocking member.
[0125] In some embodiments, the upper seat 101 and the lower seat 102 have corresponding shapes, and the two may be adapted to be connected.
[0126] In some embodiments, the upper seat 101 includes the upper connector, and the upper connector is connected to the upper support member 200. The lower seat 102 is similar to the upper seat 101, and is provided with the lower connector, and the lower connector is connected to the lower support member 300. The upper connector and the upper seat 101, and the lower connector and the lower seat 102 may be monolithic. For example, different features of a same component may be made of different components that are fixedly connected. In some embodiments, the upper connector and the lower connector may also be apertures adapted to fit into pipe fittings, into which the pipe fittings may be inserted to achieve the fixation.
[0127] The torsion spring 103 refers to a mechanical part that works by using elasticity. The operation principle of the torsion spring is to utilize elastic deformation properties of materials, torsion deformation of the torsion spring occurs under an action of an external force, and the torsion spring may be restored to its original state when the external force is removed.
[0128] In some embodiments, the two ends of the torsion spring are fixedly connected to the upper seat and the lower seat, respectively. And under the action of the torsion spring 103, the upper seat 101 may rock relative to the lower seat 102 when the camping chair is pushed or leaned on, thereby causing the camping chair to rock.
[0129] In some embodiments, there may be a plurality of ways to realize the fixed connection of the torsion spring to the upper seat and the lower seat. For example, the upper seat 101 and the lower seat 102 may be provided with mounting holes or mounting grooves, and the two ends of the torsion spring 103 are respectively snapped into the mounting holes or the mounting grooves, thereby realizing the fixation. As another example, the upper seat 101 and the lower seat 102 may be provided with lugs, and the two ends of the torsion springs 103 are inserted into the lugs to achieve the fixation.
[0130] In some embodiments, the rocking member 100 further includes a cushion 104, a spacer 105, a screw 106, a bolt 107, and a torsion spring retainer 108, as shown in
[0131] In some embodiments, a count of the torsion spring 103 is one or more, each torsion spring 103 have the same or different diameters at both ends, and the each torsion spring 103 is provided with a sound insulating sleeve on an outer side.
[0132] It is to be understood that if only for realizing a rocking function of the camping chair, the count of the torsion spring 103 may be set to one, and the two ends are fixed with the upper seat 101 and the lower seat 102 respectively. If a balanced degree of rocking of the camping chair is also considered, the torsion springs 103 may be set to two or more.
[0133] In some embodiments, the diameters of the two ends of the torsion spring 103 may be the same or different. In this regard, when the torsion spring 103 is squeezed by the external force, the different diameters of the two ends of the torsion spring 103 may provide space for a contraction of the torsion spring, which facilitates the contraction deformation of the torsion spring. The diameters of the torsion spring refer to a sum of diameters of coils that make up the torsion spring. The diameters of the two ends of the torsion spring are diameters of the coils that make up the two ends of the torsion spring.
[0134] In some embodiments, the outer side of the torsion spring 103 may also be provided with the sound insulating sleeve. For example, the sound insulating sleeve is disposed between the torsion spring 103 and the upper seat, with the sound insulating sleeve covering the torsion spring 103.
[0135] The sound insulating sleeve refers to a component that insulates the sound emitted when the torsion spring deforms. In some embodiments, material of the sound insulating sleeve may be a sound-insulating material, for example, acoustic foam cotton, or the like.
[0136] In some embodiments of the present disclosure, by setting different counts of the torsion springs, different needs for designing the camping chair can be met; by setting different diameters of the torsion springs, it is conducive to deformation contraction of the torsion springs; and by setting the sound insulating sleeve on the outer side of the torsion spring, the noise emitted during deformation of the torsion springs can be reduced, providing a good user experience.
[0137] In some embodiments, the rocking member further includes a first adjusting member and a second adjusting member, and more details regarding this section may be found in other contents of the present disclosure (e.g., description in connection with
[0138] In some embodiments of the present disclosure, by setting the rocking member to include the torsion spring, resistance provided by the torsion spring as it deforms can be fully utilized to achieve the rocking of the camping chair.
[0139]
[0140] In some embodiments, as shown in
[0141] More details regarding the upper seat 101 and the lower seat 102 may be found in other contents of the present disclosure (e.g., descriptions in connection with
[0142] The rotation axis 111 refers to a shaft component about which the upper seat and the lower seat rotate when the rocking member rocks. In some embodiments, the upper seat 101 and the lower seat 102 rotate about the rotation axis 111.
[0143] The resilient pad 112 refers to a component that provides restoring force and cushioning. The resilient pad 112 may be made of resilient materials, such as resilient rubber, resilient plastics, resilient metals (e.g., a copper alloy), and composite materials (e.g., a fiber-reinforced composite).
[0144] In some embodiments, the resilient pad 112 is provided between the upper seat 101 and the lower seat 102. The middle of the resilient pad 112 may be provided with a curved groove that fits with the rotation axis, avoiding relative scampering of the resilient pad 112 with the upper seat 101 or the lower seat 102 during the rocking of the camping chair.
[0145] The tension spring 113 refers to a helical spring that is subjected to axial tension and is also called an extension spring. When not subjected to loads, coils of the tension spring are tightened without clearance between the coils. The operation principle of the tension spring is to produce a reverse action when the tension spring is stretched or pulled apart. For example, when the tension spring is stretched or pulled apart, it tries to return to its original state, providing a reverse tension. In some embodiments, the upper end of the tension spring 113 is fixedly connected to the upper seat 101, and the lower end of the tension spring 113 is fixedly connected to the lower seat 102 for providing the restoring force to the upper seat and the lower seat.
[0146] In some embodiments, the tension spring 113 is provided on one side of the resilient pad 112, such as a front side, as shown in
[0147] In some embodiments, the rocking member is provided with one or more mounting positions for the tension spring, with different mounting positions corresponding to different initial lengths of the tension spring.
[0148] For example, at least one of the upper seat 101 or the lower seat 102 may be provided with a plurality of lugs (e.g., a plurality of mounting positions) for the tension spring. When the tension springs 113 are of a same type, different lugs correspond to different initial lengths of the tension springs 113, and the different initial lengths may correspond to a plurality of different tensions, so that the upper support member 200 has different initial positions, which may also correspond to different rocking ranges of the camping chair.
[0149] Exemplarily, the tension spring 113 is in an elongated state when the initial length of the tension spring 113 is long, and when the tension spring 113 is provided in a front side orientation of the camping chair, the initial position of the camping chair is tilted forward, and at this time a large thrust is required when leaning backward to make the camping chair to rock backward. Conversely, when the camping chair rocks backward and begins to spring back, it may spring back quickly (rock forward quickly) due to a high tension of the tension spring. For example, when the initial length of the tension spring 113 is close to a length of a natural elongation of the tension spring 113, the restoring force decreases, and the camping chair rocks slowly.
[0150] In some embodiments of the present disclosure, by setting different mounting positions for the tension springs, the initial lengths of the tension springs are different, which in turn makes the tension of the tension springs different, and makes the camping chairs have different rocking ranges and be applicable to use needs of different people.
[0151] In some embodiments of the present disclosure, by adding the tension spring in the front side orientation of the camping chair, the initial position of the camping chair is tilted forward. When using the camping chair, the user only needs to try his or her best to lean backward, which can be realized by his or her own gravity to rock backward and does not increase the difficulty of pushing. And during the rebound, due to the relatively strong restoring force provided by the contraction tendency of the tension spring, it can quickly and conveniently rock forward, enhancing the user experience.
[0152]
[0153] In some embodiments, as shown in
[0154] More details regarding the upper seat 101, the lower seat 102, the rotation axis 111, and the resilient pad 112 may be found in other contents of the present disclosure (e.g., descriptions in connection with
[0155] The compression spring 121 refers to a helical spring that is subjected to axial pressure, also known as a compression spring. When not subjected to a load, there is a gap between the coils of the compression spring. The operation principle of the compression spring is that when subjected to an external load, the compression spring shrinks and deforms, thereby storing deformation energy and providing a reverse elasticity. In some embodiments, the upper end of the compression spring 121 is fixedly connected to the upper seat 101 and the lower end of the compression spring 121 is fixedly connected to the lower seat 102. The fixed connection is similar to that of a tension spring, and is not described herein.
[0156] In some embodiments, the compression spring 121 is provided on one side of the resilient pad 112, such as a rear side, as shown in
[0157] In some embodiments, the compression spring 121 may also be disposed on both sides of the resilient pad 112, such as a front side and a rear side. In some embodiments, the compression springs 121 on the front side and the rear side are compressed differently when installed to allow the upper support member 200 to tilt slightly toward the front side when the camping chair is not in use. When the user leans backward on the camping chair, the upper support member 200 rocks backward, at which time the compression spring 121 on the front side gradually recovers its original length to further provide a force for rocking backward, while the compression spring 121 in the rear side is in a state of further compression, and the elasticity of the compression spring 121 in the rear side (the compression spring is compressed with a tendency to elongate back to its original length) prompts the upper support member 200 to have a tendency to rock forward, so as to realize the back and forth swinging of the camping chair. In this regard, the compression spring on the front side and the compression spring on the rear side may be the same type of compression springs with different lengths, and the compression spring compressed on the front side is shorter than the compression spring compressed in the rear side during installation to allow the upper support member 200 to be tilted slightly toward the front side.
[0158] In some embodiments of the present disclosure, by adding the compression spring in a rear side orientation of the camping chair, the initial position of the camping chair is tilted forward. When using the camping chair, the user only needs to try his or her best to lean backward, which can be realized by his or her own gravity to rock backward and does not increase the difficulty of pushing. And during the rebound, due to the relatively strong restoring force provided by the tendency to elongate of the compression spring, it can quickly and conveniently rock forward, enhancing the user experience.
[0159]
[0160] In some embodiments, the rocking member 100 includes the upper seat 101, the lower seat 102, the rotation axis 111, the resilient pad 112, the tension spring 113, and the compression spring 121, as shown in
[0161] More details regarding the upper seat 101, the lower seat 102, the rotation axis 111, the resilient pad 112, the tension spring 113, and the compression spring 121 may be found in other contents of the present disclosure (e.g., descriptions in connection with
[0162] In some embodiments, the tension spring 113 is provided on a front side of the resilient pad 112 and the compression spring 121 is provided on a back side of the resilient pad 112, as illustrated in
[0163] In some embodiments of the present disclosure, power is provided to the camping chair by a combination of the tension spring and the compression spring, which can make the force required by the user to use the camping chair become small, and improve the user experience.
[0164] In some embodiments, there are a plurality of ways to use the torsion spring, the compression spring, and the tension spring. The torsion spring, the compression spring, and the tension spring may be used individually or in combination. For example, in addition to the above-described ways of use involved, the ways of using may further include setting up both the torsion spring and the tension spring, setting up both the torsion spring and the compression spring, or the like.
[0165] In some embodiments, the torsion spring, the compression spring, and the tension spring may be provided in any other feasible position. For example, the compression spring or the tension spring may be provided in the middle of the rocking member 100. As another example, the compression springs or the tension springs may be provided on both sides of the rocking member 100.
[0166]
[0167] In some embodiments, as shown in
[0168] The first adjusting member 131 refers to a component that adjusts the elasticity of the torsion spring. For example, a manual rotary knob, or the like.
[0169] In some embodiments, the first adjusting member 131 may be fixedly connection to the torsion spring 103. There may be a plurality of ways to effectuate a fixed connection of the first adjusting member 131 to the torsion spring 103. For example, a torsion spring mounting hole is provided on the circumference of the first adjusting member 131, and the torsion spring 103 is secured in the mounting hole. As another example, the first adjusting member 131 is provided with a lug protrusion close to an end face of the torsion spring, and the torsion spring 103 is fixed in the lug.
[0170] In some embodiments, the difficulty degree of rocking may characterize an amount of force required to rock the camping chair. The difficulty degree of rocking may be characterized by a numerical value, where a larger numerical value indicates that it is more difficult to wobble the camping chair, and a smaller numerical value indicates that it is easier to wobble the camping chair.
[0171] In some embodiments, the greater the compression of the torsion spring (i.e., the tighter the torsion spring is compressed), the greater the force required to rock the camping chair, corresponding to a higher difficulty degree of rocking, and the more difficult it is to rock the camping chair. The less compression of the torsion spring, the less force required to rock the camping chair, corresponding to a lower difficulty degree of rocking, and the easier it is to rock the camping chair.
[0172] In some embodiments, the first adjusting member may be in the threaded connection with either the upper seat 101 or the lower seat 102. For example, the first adjusting member may be a rotary knob, and by rotating the first adjusting member, the first adjusting member moves relative to the upper seat 101 or the lower seat 102, which in turn drives a lateral deformation (stretching or compression) of the torsion spring.
[0173] As shown in
[0174] In some embodiments, thread directions of the first adjusting members 131 on the left side and the right side may be opposite (i.e., one is a left-handed thread and the other is a right-handed thread), or the thread directions of the first adjusting members 131 on the left side and the right side are the same, but is opposite to the rotation direction of the torsion spring when it is mounted. At this time, rotating the first adjusting member on the two sides respectively may make the pulling force of the torsion spring on the left hand and the torsion spring on the right hand opposite, which makes an initial position (position when not subjected to external force) of the camping chair is a centered position.
[0175] In some embodiments of the present disclosure, by setting the first adjusting member, the elasticity of the torsion spring can be flexibly adjusted, which in turn makes the difficulty degree of rocking of the camping chair in line with use habits of the user, and enhance the user experience.
[0176] In some embodiments, the first adjusting member 131 may be provided with a scale line, the scale line being configured to align with a zero position, and the zero position is a position corresponding to the torsion spring in a natural state.
[0177] In some embodiments of the present disclosure, a provision of the scale line enables the user to adjust the torsion spring to a suitable position according to actual needs through the first adjusting member, and to adjust the force required for the rocking of the camping chair.
[0178] In some embodiments, the rocking member further includes a second adjusting member, and the second adjusting member adjusts the difficulty degree of rocking of the camping chair by adjusting the elasticity of the torsion spring.
[0179] The second adjusting member refers to a component that adjusts the elasticity of the torsion spring. For example, a motorized rotary knob, or the like.
[0180] In some embodiments, the second adjusting member includes a microprocessor, a drive device, an input device, and a communication device; and the microprocessor is configured to determine an adjustment instruction. The drive device is configured to adjust the elasticity of the torsion spring based on the adjustment instruction; and the drive device is connected to the first adjusting member or the torsion spring. The input device is configured to input a wobble sensitivity of a current user, and the wobble sensitivity is used to measure the difficulty degree of rocking of the camping chair. The communication device is configured to communicate with the drive device, the input device and the microprocessor.
[0181] The microprocessor refers to a central processor consisting of an integrated circuit. For example, an embedded microprocessor, or the like. In some embodiments, the microprocessor may determine and execute the adjustment instruction and process various data in the second adjusting member.
[0182] The drive device refers to a component that is configured to control the tightening and loosening of the torsion spring. For example, a motor, or the like. In some embodiments, the drive device may be disposed close the torsion spring of the camping chair for tightening or loosening the torsion spring based on the adjustment instruction for the purpose of adjusting the torsion spring. In some embodiments, the manner in which the drive device controls the tightening or loosening of the torsion spring may be multiple. For example, the drive device is connected to the first adjusting member to drive the torsion spring to be tightened or loosened by controlling a rotation angle of the first adjusting member. As another example, without the need for the first adjusting member, the drive device is directly connected to the torsion spring to drive the torsion spring to be tightened or loosened. In some embodiments, the drive device may return the torsion spring to an initial state prior to each adjustment; and the initial state may be either the torsion spring is fully torqued loose or fully torqued tight. Fully torqued loose refers to a state that the torsion spring is in a natural elongation state, and fully torqued tight refers to a state that the torsion spring is in a state in which it is fully compressed and no longer be twisted.
[0183] The input device refers to a device that is configured to pass user input to the microprocessor or other electronic device. In some embodiments, the input device may be set in any feasible position, for example, on the camping chair (e.g., on one side of the rocking member, on an upper tube), on an external device (e.g., a remote control device), embedded in a client, or the like.
[0184] In some embodiments, forms of the input device may include a touchable display, a normal key panel, a knob for gear adjustment, or the like. In some embodiments, a choice of the forms of the input device may be set as desired. For example, when the current user has fewer wobble sensitivity gears, a common low-grammed key panel may be selected.
[0185] In some embodiments, the input device is configured to input the wobble sensitivity of the current user.
[0186] The wobble sensitivity refers to a sensitivity degree of a user to the difficulty degree of rocking of the camping chair, and may characterize a preference choice of the user of the difficulty degree of rocking of the camping chair. In some embodiments, the wobble sensitivity may be represented in a plurality of ways. For example, the wobble sensitivity may be represented by a plurality of preset grades such as flexible, more flexible, and stable. The flexible grade refers that it is easier to rock the camping chair and the stable grade refers that it is more difficult to rock the camping chair. As another example, the wobble sensitivity may also be represented by a discrete value from 0 to 100, and the higher the discrete value, the higher the wobble sensitivity, corresponding to the more difficult rocking of the camping chair.
[0187] In some embodiments, the microprocessor is set up in a similar position as the input device. For example, the microprocessor may be the processor of a cell phone of the user when the input device is the diaplay of the cell phone of the user.
[0188] The communication device refers to a component that is configured to communicate and connect with other devices, and to transfer data and instructions. For example, the communication device may be a network card, a modem, a fiber optic transceiver, or the like. In some embodiments, the communication device may be provided in the drive device, the input device, and the microprocessor.
[0189] In some embodiments, the input device and the microprocessor are preferred to be located in an external device or embedded in the client to make the chair lighter overall.
[0190] In some embodiments, the user inputs the wobble sensitivity via the input device, and the microprocessor may obtain the wobble sensitivity via the communication device and determine an adjustment instruction based on the wobble sensitivity.
[0191] The adjustment instruction refers to an instruction for adjusting the difficulty degree of rocking of the camping chair. In some embodiments, the adjustment instructions may include rotation directions and number of rotations of each torsion spring.
[0192] In some embodiments, the microprocessor may determine the adjustment instruction in a plurality of ways. For example, the microprocessor may obtain, from the communication device, the wobble sensitivity entered by the user via the input device, and determine the adjustment instruction, via a preset table based on the wobble sensitivity.
[0193] The preset table may include a correspondence relationship between the wobble sensitivity and the adjustment instruction. In some embodiments, the preset table may be obtained in a plurality of ways. For example, the preset table may be constructed based on experimental data. Exemplarily, the user tightens or loosens the torsion spring, tests and records the wobble sensitivities at different numbers of rotations, averages a plurality of wobble sensitivities corresponding to a same rotation direction and a same number of rotations for a plurality of tests, and records the average value of the wobble sensitivities into the preset table to determine the rotation direction and the number of rotations and the corresponding wobble sensitivity (to determine the adjustment instruction and the corresponding wobble sensitivity).
[0194] In some embodiments of the present disclosure, motorized adjustment of the camping chair can be realized by setting the second adjusting member, which makes it convenient for the user to use the camping chair. The input device can reduce a difficulty of adjusting the difficulty degree of rocking of the camping chair and improve the user experience. For example, the user can adjust the chair by directly selecting the corresponding buttons, without having to think about which direction to rotate in, and how far to rotate to achieve a flexibility degree.
[0195] In some embodiments, the second adjusting member further includes a monitoring recorder and a cloud-based database. The monitoring recorder is configured to monitor and record wobble data of the current user and the wobble sensitivity. The cloud-based database is configured to periodically collect and store the wobble data and the wobble sensitivity obtained by the monitoring recorder. The input device is further configured to input an adaptive mode, and the adaptive mode is configured to periodically determine the wobble sensitivity based on the cloud-based database.
[0196] The monitoring recorder refers to a component that monitors and records the wobble data the current user and the wobble sensitivity.
[0197] The wobble data of the current user refers to data related to wobble situation of the camping chair that is used by a user. In some embodiments, the wobble data of the current user may be obtained in a plurality of ways. For example, the wobble data of the current user may be obtained through the monitoring recorders such as an inclination sensor, a displacement sensor, or the like.
[0198] In some embodiments, the monitoring recorder may obtain the adjustment instruction via the communication device, and determine the wobble sensitivity of the current user based on the adjustment instruction. In this regard, determining the wobble sensitivity of the current user based on the adjustment instruction may be accomplished by querying the preset table.
[0199] The cloud-based database refers to a component that periodically collects and stores the wobble data and the wobble sensitivity from the monitoring recorder. In some embodiments, the wobble data and the wobble sensitivities of a large number of users are stored in the cloud-based database, including, but not exclusively only, the wobble data of the current user and the wobble sensitivities.
[0200] The adaptive mode refers to a mode in which the wobble sensitivity may be adaptively adjusted based on behaviors of the user without user inputs. In some embodiments, the adaptive mode may be set by the user via the input device for periodically and autonomously determining the wobble sensitivity based on the cloud-based database.
[0201] In some embodiments, periodically determining the wobble sensitivity based on the cloud-based database includes: periodically obtaining the wobble data of the current user and the wobble sensitivity for a previous cycle from the monitoring recorder; obtaining a vector database from the cloud-based database; and determining, by the vector database, the wobble sensitivity for a current cycle of the current user, based on the wobble data and the wobble sensitivity of the current user for the previous cycle. The cycle may be set by the microprocessor by default or by the user autonomously. For example, 1 day, 1 week, or the like.
[0202] In some embodiments, ways of obtaining the vector database based on the cloud-based database may include multiple. For example, based on the cloud-based database, the wobble data and the wobble sensitivities for a plurality of historical first cycles and a plurality of historical second cycles are obtained, with the historical second cycle being after the historical first cycle and the historical second cycle being the next cycle of the historical first cycle. A to-be-clustered vector is constructed by using the wobble data and the wobble sensitivities of the historical first cycle and the wobble sensitivities of the historical second cycle corresponding to the historical first cycle, and then a plurality of to-be-clustered vectors are constructed based on the cloud-based database. The plurality of to-be-clustered vectors are clustered to form a plurality of clustering centers, and a clustering center includes the wobble data of the historical first cycle, the wobble sensitivity of the historical first cycle, and the wobble sensitivity of the historical second cycle corresponding to the historical first cycle. The wobble data and the wobble sensitivity of the historical first cycle corresponding to one of the clustering centers are determined as a criterion vector, the wobble sensitivity of the historical second cycle corresponding to the clustering center is determined as a label of the criterion vector, and then a plurality of criterion vectors and the corresponding plurality of labels are determined based on the plurality of clustering centers, and the vector database is constructed based on the plurality of criteria vectors and the corresponding plurality of labels.
[0203] In some embodiments, there are a plurality of ways of determining the wobble sensitivity for the current cycle of the current user via the vector database, based on the wobble data and the wobble sensitivity for the previous cycle of the current user. For example, a to-be-matched vector is constructed based on the wobble data and the wobble sensitivity of the current user for the previous cycle, and a plurality of vector similarities between the to-be-matched vector and the plurality of criterion vectors in the vector database are calculated. The label corresponding to the criterion vector with the highest vector similarity is used as the wobble sensitivity for the current cycle of the current user. The vector similarity may be expressed by cosine similarity, Euclidean distance, or the like.
[0204] As another example, an average of the plurality of wobble sensitivities for the previous cycle of the current user is used as the wobble sensitivity for the current cycle of the current user.
[0205] In some embodiments of the present disclosure, the wobble sensitivity can be automatically adjusted according to the behaviors of the user by setting the adaptive mode, which does not require any additional operation by the user, and improves the user experience.
[0206] In some embodiments, the second adjusting member further includes a reminder component, the reminder component being configured to display a reminder message to the current user. The input device is also configured to receive user update feedback and user update requests. The monitoring recorder is also configured to record a count of user adjustments. The microprocessor is further configured to: in response to determining that an update triggering condition is satisfied, generate the reminder message and send the reminder message to the reminder component, the update triggering condition including that the input device receives the user update request, and/or the count of user adjustments the user in a predetermined time period is greater than a predetermined threshold.
[0207] The reminder component refers to a component that displays the reminder message to the user. The reminder message refers to a message related to reminding the user to make an update. In some embodiments, the reminder component may be provided in any feasible position, for example, located on an external device, embedded in a client, or the like. Exemplarily, the reminder component may be the same device as the input device (e.g., the display of the cell phone of the user), and the reminder component may also be a speaker within the cell phone of the user or a separately set speaker, or the like.
[0208] In some embodiments, different reminder components display the reminder message to the current user in different ways. For example, the display may be reminded by text, the speaker may be reminded by voice, or the like.
[0209] The user update feedback refers to information about a feedback by a user to update the vector database. In some embodiments, the user update feedback may include update or no update. Exemplarily, the user update feedback may be represented by a boolean value, for example, 1 for update and 0 for no update.
[0210] The user update request refers to information about a request by a user to update the vector database. In some embodiments, the user update request may include an update request or no update request. Exemplarily, the user update request may be represented by a boolean value, with 1 representing an update request and 0 representing no update request.
[0211] The count of user adjustments refers to a count of times a user has made adjustments to the first adjusting member or the second adjusting member. For example, the count of user adjustments may be a count of automatic or manual adjustments of the second adjusting member or a count of manual adjustments of the first adjusting member.
[0212] The update triggering condition refers to a trigger condition that updates the vector database. In some embodiments, the update triggering condition includes that the input device receives the user update request, and/or the count of user adjustments in the predetermined time period is greater than the predetermined threshold. The predetermined time period refers to a predetermined period of time, for example, 0.5 h, 1 h, or the like. The predetermined threshold refers to a maximum value of the count of user adjustments in the predetermined time period when there is no need to update the vector database. In some embodiments, the predetermined time period and the predetermined threshold may be set by default by the microprocessor or preset by a technician based on user needs or historical experience.
[0213] In some embodiments, in response to determining that the update triggering condition is satisfied, the microprocessor may generate the reminder message and send the reminder message to the reminder component. For example, in response to determining that the user update request of 1 is obtained from the input device, the microprocessor may generate a voice reminder Please update the vector database! and send it to the speaker.
[0214] In some embodiments, after the update triggering condition is satisfied, in response to determining that the user update feedback is received as an update (e.g., 1), the microprocessor may update the vector database, to prevent the user update request from being a user mis-trigger. In this regard, updating the vector database includes: based on the latest uploaded data in the cloud-based database and historical data within a historical time period, reclustering to form new criterion vectors and labels to form a new vector database. The historical time period refers to a time period before the current moment. In some embodiments, a duration of the historical time period may be set by the microprocessor by default or preset manually based on user needs or empirical values.
[0215] In some embodiments of the present disclosure, after satisfying the update triggering condition, the database is updated based on confirming the update feedback, and by confirming it twice, the false touch can be effectively prevented; at the same time, the user can take the initiative to update the database to more quickly match a close adaptive mode to meet adjustment needs of the user.
