In the specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0045] Referring to FIGS. 1 to 11, in accordance with an embodiment of a first aspect of the present disclosure, a desk board component is provided, including a first desk board 100, a second desk board 200 and a connecting member 300. The second desk board 200 is arranged above the first desk board 100, and the second desk board 200 protrudes further than an edge of the first desk board 100. A part of the second desk board 200 protruding further than the first desk board 100 defines a mounting part 210. In a vertical direction, an area of the second desk board 200 within a projection range of the first desk board 100 is a main body part 220. The mounting part 210 is provided with a first bearing surface 211. The main body part 220 is provided with a second bearing surface 221. The first bearing surface 211 is configured to carry at least a part of an object. When the object to be carried is small, such as a display holder or a desk lamp, it can be carried only by the first bearing surface 211. When the object to be carried is large, the first bearing surface 211 and the second bearing surface 221 jointly carry the object. A side of the mounting part 210 facing away from the first bearing surface 211 defines a mounting space 213 for accommodating a clamping mounting component 400, and the mounting part 210 is configured to mount the clamping mounting component 400. The connecting member 300 connects the first desk board 100 and the second desk board 200. It should be noted that dotted lines in FIGS. 1, 2 and 3 cannot be interpreted as outlines of the desk, and are only provided for a convenience of distinguishing the main body part 220 from the mounting part 210.

[0046] The desk board component according to the embodiment of the present disclosure has at least the following beneficial effects. The second desk board 200 is arranged above the first desk board 100, the second desk board 200 is provided with the mounting part 210 protruding further than the edge of the first desk board 100, the mounting part 210 is provided with the first bearing surface 211, and the mounting space 213 is provided at the side facing away from the first bearing surface 211, so that the external clamping mounting component can be accommodated in the mounting space 213 and the object can be fixed on the mounting part 210, thereby realizing a purpose of fixing the object on the second desk board 200.

[0047] Further, the mounting space 213 can also provide a large enough operation space for a user's hand, so the user can conveniently and quickly mount the clamping mounting component 400 on the mounting part 210. Therefore, the object can be fixed on the second desk board 200, thereby improving the user's operation experience. In some embodiments, a distance that the mounting part 210 protrudes further than the edge of the first desk board 100 is less than or equal to

[00001]$\frac{1}{2}S,$

where S is a length of the second desk board 200 in a protruding direction of the mounting part 210.

[0048] In the related technology, in a case that a desk has two stacked desk boards, since a distance between the two desk boards should be set according to a design requirement, when assemblies such as the clamping mounting component 400 need to be mounted on an upper desk board, the distance between the two desk boards is not sufficient, which causes a user to be unable to smoothly adjust the clamping mounting component. For example, when the clamping mounting component 400 is provided with a fastening member 410, it is difficult for the user to twist the fastening member 410 to fix the clamping mounting component 400 on the upper desk board, or the clamping mounting component cannot fit directly into an area between the two desk boards, thereby making the desk less convenient to use. In the present disclosure, the second desk board 200 protrudes further than the edge of the first desk board 100 to define the mounting part 210, and the mounting space 213 is formed below the mounting part 210, so that the clamping mounting component 400 can be accommodated in the mounting space 213 and connected to the mounting part 210, and the clamping mounting component 400 can be easily placed between the first desk board 100 and the second desk board 200. Meanwhile, the user's hand can also stretch into the mounting space 213, that is, the mounting space 213 provides the large enough operation space for the user's hand, thereby smoothly adjusting members in the clamping mounting component 400 to connect the clamping mounting component 400 to the mounting part 210 or remove the clamping mounting component 400 from the mounting part 210.

[0049] It should be noted that, for example, when a shape of the first desk board 100 is a cuboid, that is, the first desk board 100 has a predefined length direction and a predefined width direction, the second desk board 200 can protrude further than the edge of the first desk board 100 along the length direction and/or the width direction to define the mounting part 210. When the edge of the first desk board 100 is arc-shaped, the second desk board 200 protrudes further than the edge of the first desk board 100 along a radial direction corresponding to the arc to define the mounting part 210. In practical application, the shape of the first desk board 100 may also be L-shaped, and a shape of the second desk board 200 may also be L-shaped corresponding to the shape of the first desk board 100.

[0050] Specifically, both a connection between the connecting member 300 and the first desk board 100, and a connection between the second desk board 200 and the connecting member 300 may be configured to be detachable, for example, by means of screw connection, etc. When the second desk board 200 is not used, the second desk board 200 may be detached, so that the desk has greater flexibility in use.

[0051] Referring to FIGS. 8 and 9, in some embodiments, the clamping mounting component 400 includes a rotary driving structure 460, a pressing member 420 and an abutting member 450. At least a part of the abutting member 450 abuts against the first bearing surface 211. The pressing member 420 is located on the side of the mounting part 210 facing away from the first bearing surface 211. The rotary driving structure 460 is connected to the abutting member 450. The rotary driving structure 460 is configured to drive the pressing member 420 to approach the abutting member 450. The following is explained by two specific embodiments.

[0052] Referring to FIG. 9, in some embodiments, the rotary driving structure 460 includes a nut 461 and a fastening member 410. The abutting member 450 is arranged above the first bearing surface 211, and configured to connect an object. The pressing member 420 and the abutting member 450 respectively abut against two sides of the mounting part 210. The fastening member 410 penetrates the mounting hole 212 and connects the pressing member 420 and the abutting member 450. The fastening member 410 may be a screw. During a processing of mounting an object, the object can be connected to a side of the abutting member 450 facing away from the first bearing surface 211 by, for example, a threaded fastening member. Alternately, the object may be at least partially placed on the first bearing surface 211 and arranged between the abutting member 450 and the mounting part 210. In a process of connecting the clamping mounting component 400 to the mounting part 210, the fastening member 410 ensures the fixation, and the nut 461 is screwed on the fastening member 410 and abuts against the pressing member 420, so that the pressing member 420 is driven to move towards the abutting member 450. The mounting part 210 is clamped between the pressing member 420 and the abutting member 450 due to opposing forces of the pressing member 420 and the abutting member 450, thus the clamping mounting component 400 is mounted on the mounting part 210.

[0053] Referring to FIG. 8, in some embodiments, the abutting member 450 includes a first mounting member 430 and a second mounting member 440. The rotary driving structure 460 includes a fastening member 410. The first mounting member 430 includes a pressing part 431 for connecting objects and a first adjusting part 432 extending downward in a direction away from the bearing surface. The second mounting member 440 includes a second adjusting part 441 and a fixing part 442. The second adjusting part 441 is connected to the first adjusting part 432, and the fixing part 442 is opposite to the second desk board 200. The fixing part 442 is provided with an adjusting hole 443, and the fastening member 410 passes through the adjusting hole 443. The pressing member 420 is connected to an end of the fastening member 410, and configured to abut against the side of the mounting part 210 facing away from the first bearing surface. The adjusting hole 443 may be a threaded hole, and the fastening member 410 may be a threaded fastening member such as a screw. In a process of fixing an object to the mounting part 210, the pressing member 420 is driven to move to the mounting part 210 in the vertical direction by screwing the fastening member 410 into the adjusting hole 443 and adjusting a screwing position, until the pressing member 420 is pressed against the mounting part 210, so that the mounting part 210 is clamped between the pressing member 420 and the abutting member 450, thus the clamping mounting component 400 is mounted on the mounting part 210.

[0054] Specifically, an object can be connected to the side of the abutting member 450 facing away from the first bearing surface 211 by, for example, a threaded fastening member, and the clamping mounting component 400 can be mounted on the mounting part 210 by forces facing each other as the pressing member 420 is pressed against the mounting part 210. Alternatively, the object may be at least partially arranged between the abutting member 450 and the mounting part 210 during mounting, and the pressing member 420 and the mounting part 210 respectively apply forces facing each other, so that the object is pressed between the pressing part 431 and the mounting part 210 to realize a fixation of the object on the mounting part 210, and the clamping mounting component 400 is mounted on the mounting part 210.

[0055] In some embodiments, the second adjusting part 441 is capable of moving relative to the first adjusting part 432 in the vertical direction to change a distance between the fixing part 442 and the pressing part 431, so that the clamping mounting component 400 is capable of adapting to the second desk board 200 with different thicknesses.

[0056] Specifically, in the first mounting member 430, one end of the first adjusting part 432 and one end of the pressing part 431 are connected. The first adjusting part 432 and the pressing part 431 form an included angle, for example, a right angle, so that first mounting member 430 is generally L-shaped. Similarly, in the second mounting member 440, one end of the second adjusting part 441 and one end of the fixing part 442 are connected. The second adjusting part 441 and the fixing part 442 form an included angle, for example, a right angle, so that second mounting member 440 is generally L-shaped. When the first mounting member 430 and the second mounting member 440 are assembled and connected, that is, the second adjusting part 441 and the first adjusting part 432 are connected, the first mounting member 430 and the second mounting member 440 are generally C-shaped with an opening facing the desk, so that a connecting position of the first mounting member 430 and the second mounting member 440 is exposed on a side away from the desk, which is convenient for a user to adjust a relative position of the first mounting member 430 and the second mounting member 440 in the vertical direction, and in turn adjust distance between the second mounting member 440 and the second desk board 200.

[0057] Referring to FIG. 10, in some embodiments, the first adjusting part 432 may be provided with a plurality of fixing holes 433 along an extension direction, and the fixing holes 433 penetrate along a thickness direction of the first adjusting part 432. The second adjusting part 441 is provided with a threaded hole, and the second mounting member 440 is fixed to the first mounting member 430 by the threaded fastening member passing through the fixing holes 433 and screwing in the threaded hole. When adjustment is needed, the threaded fastening member is screwed out of the threaded hole, then the second mounting member 440 is moved until the threaded hole is coaxial with a corresponding one of the fixing holes 433, and then the threaded fastening member is screwed back into the threaded hole, which is convenient and quick to adjust.

[0058] Referring to FIG. 11, in some other embodiments, the first adjusting part 432 may be provided with an adjusting groove 434 along the extension direction, and the adjusting groove 434 penetrates along the thickness direction of the first adjusting part 432. The second adjusting part 441 is provided with a threaded hole, and the second mounting member 440 is fixed to the first mounting member 430 by threaded fastening member passing through the fixing hole 433 and screwing in the threaded hole. Steps of adjusting a position of the second mounting member 440 are the same as those in the above-mentioned embodiment in which the fixing holes 433 are provided, and will not be repeated here. However, when the first adjusting part 432 is provided with the adjusting groove 434, the second mounting member 440 can realize stepless adjustment in the vertical direction relative to the first mounting member 430, which makes the use of the clamping mounting component 400 more accurate and convenient.

[0059] Referring to FIG. 3, in some embodiments, the mounting part 210 is further provided with a mounting hole 212, which runs through in the vertical direction and is configured to be at least partially penetrated by the clamping mounting component 400. For example, in the clamp mounting component 400 of the above embodiment, the fastening member 410 is inserted into the mounting hole 212, so that the abutting member 450 and the pressing member 420 are located at two sides of the mounting part 210, and an object can be fixed to the clamp mounting component 400 and located above the second desk board 200. The mounting hole 212 can be located in the middle of the mounting part 210 in the width direction to adapt to the clamping mounting component 400 with different sizes, and ensure that the clamping mounting component 400 can be accommodated in the mounting space 213 without interfering with the first desk board 100 or the connecting member 300. It should be understood that the mounting part 210 may be provided with a plurality of mounting holes 212 configured to be at least partially penetrated respectively by various clamping mounting components 400, or penetrated respectively by various fastening members 410 of the same clamping mounting component 400, so that a plurality of objects are fixed to the second desk board 200, or connected to an object by the plurality of fastening members 410, thereby increasing the connection stability.

[0060] Referring to FIGS. 1 to 3, in some embodiments, the desk board component is provided with a plurality of connecting members 300, including two first connecting members 320 spaced apart. A storage space 330 is defined between the first desk board 100, the second desk board 200 and the two first connecting members 320. In practical application, the number of the first connecting members 320 may also be three, four, five, etc., that is, there are at least two first connecting members 320. The dimensions of the second connecting member 310 and the first connecting member 320 are equal in the vertical direction to support the second desk board 200, and the second desk board 200 is arranged horizontally with a predefined distance from the first desk board 100, thereby realizing functions of height adjustment and storage.

[0061] Further, the desk board component includes a second connecting member 310 configured to connect the two first connecting members 320 and extend along the edge of the first desk board 100. For example, referring to FIGS. 1 to 3, the second connecting member 310 extends along the length direction, and separates the storage space 330 from the mounting space 213, so that an object located in the storage space 330 can be prevented from escaping from the storage space 330 and falling when the desk is in use.

[0062] In some embodiments, the desk board component further includes a storage box 900 having an opening facing toward the second desk board 200 and being movable relative to the second desk board 200 between a first position in which the storage box 900 is accommodated in the storage space 330 (see FIG. 2), and a second position, in which the storage box 900 is at least partially located outside the storage space 330.

[0063] Referring to FIG. 3, in some embodiments, the first connecting member 320 is vertically arranged in the vertical direction, and located within the projection range of the first desk board 100. Specifically, the second connecting member 310 is arranged along the edge of the first desk board 100, and both the second connecting member 310 and the first connecting member 320 extend upward in the vertical direction and connects to the second desk board 200 to support the second desk board 200. In the width direction, one end of the first connecting member 320 near the mounting part 210 is perpendicular to the first desk board 100, for example, the first connecting member 320 is a rectangular board or a right-angled ladder-shaped board. The mounting part 210 and the main body part 220 are integrated as an integral structure, for example, the mounting part 210 and the main body part 220 are integrated as a rectangular desk board staggered relative to the first desk board 100, so that the mounting part 210 protrudes further than the edge of the first desk board 100.

[0064] Referring to FIGS. 1 and 2, in other embodiments, one end of the first connecting member 320 is connected to the first desk board 100, and another end of the first connecting member 320 extends obliquely upward and is connected to the second connecting member 310. At least a part of the first connecting member 320 protrudes in the width direction further than an edge of the first desk board 100. A distance that the first connecting member 320 protrudes in the width direction further than the edge of the first desk board 100 may be equal to or slightly smaller than the distance that the second desk board 200 protrudes in the length direction further than the edge of the first desk board 100 to better support the second desk board 200, so that a maximum load that the second desk board 200 can bear is increased. In a plane defined by the width direction and the vertical direction, a cross section of the first connecting member 320 taken in the width direction is a parallelogram. Compared with schemes in the related technology that outer edges of two desk boards are flush, under a premise that the size of the second desk board 200 is unchanged, in the present disclosure, the second desk board 200 is staggered relative to the first desk board 100 and protrudes further than the edge of the first desk board 100, so that an exposed area of the first desk board 100 is bigger, thereby increasing a usable area of the first desk board 100.

[0065] In some embodiments, the second desk board 200 has a predefined length, and in a length direction, from two ends of the second desk board 200 to a middle position of the second desk board 200, a distance that the mounting part 210 protrudes further than the edge of the first desk board 100 gradually increases. In a length direction, from two ends of the second desk board 200 to the middle position of the second desk board 200, a size of the mounting part 210 increases to a predefined value, which can reduce a material usage of the second desk board 200 and a manufacturing cost on one hand, and on the other hand, an edge of the mounting part 210 smoothly transitions with an edge of the main body part 220, which can reduce a possibility of a user bumping against the desk board.

[0066] Referring to FIGS. 4 to 7, in some embodiments, the mounting part 210 is capable of moving relative to the main body part 220, and the mounting part 210 has a first state defining the mounting space 213 and a second state of being accommodated. When the mounting part 210 is in the first state, the mounting space 213 is defined below the mounting part 210 for accommodating the clamping mounting component 400, so that an object is fixed on the first bearing surface 211 by the clamping mounting component 400. When the mounting part 210 is in the second state, a volume occupation of the desk in a corresponding direction can be reduced. For example, referring to FIGS. 5 and 6, the mounting part 210 is moved to the second state, the volume occupation in left and right directions can be reduced, thereby meeting requirements of various usage scenarios.

[0067] Referring to FIGS. 4 and 5, in order to accommodate the mounting part 210, in some embodiments, the main body part 220 is provided with an accommodating cavity 222, and the mounting part 210 is accommodated in the accommodating cavity 222 and slidably connected to the main body part 220. The mounting part 210 is capable of sliding relative to the main body part 220 to switch between the first state and the second state. When the mounting part 210 is switched from the first state to the second state, the mounting part 210 is driven to at least partially retract into the accommodating cavity 222, thereby reducing the space occupation of the whole desk in a corresponding direction. Moreover, by setting a size of the accommodating cavity 222 in the corresponding direction, the mounting part 210 is capable of completely retracting into the accommodating cavity 222, so that the second desk board 200 does not protrude further than the edge of the first desk board 100, thereby minimizing an overall size of the desk in the corresponding direction.

[0068] In an alternative embodiment, the mounting part 210 may directly contact an inner wall of the accommodating cavity 222 to realize relative sliding. Alternatively, a guide rail may be arranged on the inner wall of the accommodating cavity 222, so that the mounting part 210 is slidably connected to the guide rail to realize a sliding connection with regard to the main body part 220.

[0069] Further, referring to FIGS. 4 and 5, in order to prevent the mounting part 210 from slipping out of the accommodating cavity 222 due to excessive sliding relative to the main body part 220, the mounting part 210 includes a moving part 214 and a limiting part 215. The limiting part 215 is arranged on a side of the moving part 214 away from an opening, and the limiting part 215 protrudes further than the moving part 214 along the edges. The desk further includes a limiting member 223 at the opening. When the mounting part 210 slides relative to the main body part 220 until it is about to come off, the limiting part 215 will abut against the limiting member 223 to limit a continued movement of the mounting part 210. It should be understood that the limiting member 223 and the main body part 220 can be arranged as an integral structure, or can be detachably connected, thereby facilitating maintenance of the mounting part 210.

[0070] Referring to FIGS. 6 and 7, in some embodiments, the mounting part 210 is rotatably connected to the main body part 220, and capable of rotating relative to the main body part 220 to switch between the first state and the second state. When the mounting part 210 is switched from the first state to the second state, the mounting part 210 is driven to rotate downward and in a direction close to the first desk board 100, so that an included angle between a side surface of the mounting part 210 facing away from the first bearing surface 211 and a side surface of the main body part 220 facing away from the second bearing surface 221 is less than 180, thereby realizing a reduction of the overall size of the desk in the corresponding direction. When the included angle between the side surface of the mounting part 210 facing away from the first bearing surface 211 and the side surface of the main body part 220 facing away from the second bearing surface 221 is 90, the overall size of the desk in the corresponding direction can be minimized.

[0071] In an alternative embodiment, one of the mounting part 210 and the main body part 220 may be provided with a rotating shaft, and the other is provided with a rotating part. The rotating part is provided with a mounting hole 212, and the rotating shaft penetrates through the mounting hole 212 to enable the mounting part 210 to rotate relative to the main body part 220. Alternatively, the mounting part 210 and the main body part 220 can be directly connected by a common hinge structure 500 to realize the rotation between the mounting part 210 and the main body part 220. Moreover, the hinge structure 500 may be arranged on a side facing away from both the first bearing surface 211 and the second bearing surface 221, so that when the mounting part 210 is in the first state, the first bearing surface 211 and the second bearing surface 221 can be seamlessly assembled. Therefore, when the first bearing surface 211 and the second bearing surface 221 jointly bear an object, a stability is stronger, and an appearance is smoother and more beautiful. It should be understood that when the mounting part 210 is rotated relative to the main body part 220 by a rotating shaft structure or a hinge, it is necessary to realize self-locking or additionally provide a supporting structure, so that the mounting part 210 can be stabilized in the first state.

[0072] Referring to FIGS. 1 and 2, in accordance to an embodiment of a second aspect of the present disclosure, a height-adjustable desk is provided, including the desk board component and a height-adjustable desk leg system. The desk board component is mounted on the height-adjustable desk leg system configured to drive the desk board component to move in the vertical direction.

The desk board component fixes the object on the mounting part 210, and can move vertically under a drive of the height-adjustable desk leg system.

[0074] Referring to FIGS. 1 and 2, in accordance to an embodiment of a third aspect of the present disclosure, a height-adjustable desk system is provided, including the clamping mounting component 400, a bracket 600, a height-adjustable desk leg system, and the desk board component provided in the embodiments of the first aspect of the present disclosure. The clamping mounting component 400 is accommodated in the mounting space 213 and connected to second desk board 200. The bracket 600 and the second desk board 200 are detachably connected through the clamping mounting component 400. The bracket 600 is configured to connect an electrical device 700. The desk board component is mounted on the height-adjustable desk leg system configured to drive the desk board component to move in the vertical direction.

[0075] The height-adjustable desk system according to the embodiment of the present disclosure has at least the following beneficial effects.

[0076] The bracket 600 is not limited to being connected with an electrical device, for example, the bracket 600 may be connected with a toy, a handicraft or other object to enhance a decorative effect of the desktop. The height-adjustable desk leg system includes a height-adjustable leg 800, and a driving mechanism configured to drive the height-adjustable leg 800 to adjust the height.
