DETAILED DESCRIPTION

[0039] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0040] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the inside and outside of the contour of each component itself. The terms "first" and "second" are used to distinguish one element from another, and do not have order or importance. In addition, when the following description refers to the drawings, the same reference numerals in different drawings represent the same or similar elements, and this disclosure will not repeat them.

[0041] According to a specific embodiment of the present disclosure, a folding structure is provided. Figures 1 to 7 An embodiment of the folding structure is shown. Figures 2 to 9 As shown, the folding structure may include a base assembly 40, a rotating assembly 30 and a support assembly 10, one end of the rotating assembly 30 is rotatably connected to the base assembly 40, and the other end is connected to the support assembly 10 through a transmission structure 50, so that the support assembly 10 can rotate relative to the base assembly 40, and the support assembly 10 has an unfolded position, a folded position and an intermediate position between the unfolded position and the folded position during the rotation relative to the base assembly 40, wherein the transmission structure 50 includes: a sliding state and a locking state, when the transmission structure 50 is in the sliding state, the support assembly 10 can move along a preset direction during the rotation relative to the base assembly 40; when the transmission structure 50 is in the locking state, the support assembly 10 is located in the unfolded position, the folded position or the intermediate position, and the transmission structure 50 can limit the movement of the support assembly 10 along the preset direction.

[0042] Through the above technical solution, in the folding structure provided by the present disclosure, since one end of the rotating assembly 30 is rotatably connected to the base assembly 40, and the other end is connected to the support assembly 10 through the transmission structure 50, the support assembly 10 can rotate relative to the base assembly 40 to be folded or unfolded relative to the base assembly 40. The transmission structure 50 provided on the rotating assembly 30 and the support assembly 10 has two states, namely, a sliding state and a locking state. When the transmission structure 50 is in the sliding state, the support assembly 10 can move in a preset direction during the rotation relative to the base assembly 40 to ensure that the support assembly 10 can be unfolded or folded relative to the base assembly 40, and to avoid interference between the support assembly 10 and the base assembly 40 during the rotation process. When the transmission structure 50 is in a locked state, the support assembly 10 is located in the unfolded position, the folded position or the intermediate position, and the transmission structure 50 in the locked state can limit the movement of the support assembly 10 in a preset direction to effectively hinder the instantaneous misalignment between the base assembly 40 and the support assembly 10. For example, when the folded structure falls, the transmission structure 50 limits the movement of the support assembly 10 in a preset direction to effectively hinder the instantaneous misalignment between the base assembly 40 and the support assembly 10, thereby effectively improving the reliability and stability of the folding structure.

[0043] It should be noted that the intermediate position should be understood as any position between the folded position and the unfolded position, that is, when the support assembly 10 rotates relative to the base assembly 40 to any position of the folded position and the unfolded position, the transmission structure 50 can limit the movement of the support assembly 10 along the preset direction. In addition, the preset direction should be understood as the extension direction of the screw sleeve 521 described below.

[0044] In the specific implementation manner provided in the present disclosure, the transmission structure 50 can be configured in any suitable manner. Figures 2 to 9 As shown, the transmission structure 50 may include a first transmission member 51 and a second transmission member 52 connected by a spiral transmission, one of which is connected to the rotating assembly 30, and the other is connected to the supporting assembly 10. The relative movement between the first transmission member 51 and the second transmission member 52 is achieved by the spiral transmission connection between the first transmission member 51 and the second transmission member 52, that is, the movement of the supporting assembly 10 along the preset direction is achieved. In addition, the spiral transmission connection between the first transmission member 51 and the second transmission member 52 needs to be achieved by the screwing of the threaded surfaces of the two threaded parts, and the screwing of the threaded surfaces can effectively hinder the instantaneous displacement between the first transmission member 51 and the second transmission member 52, that is, the instantaneous displacement between the base assembly 40 and the supporting assembly 10, thereby effectively improving the reliability and stability of the folding structure. In other embodiments of the present disclosure, the transmission structure 50 can also be configured in other ways, and the present disclosure does not impose any restrictions on this.

[0045] In the specific embodiments provided in the present disclosure, reference is made to Figures 2 to 9 As shown, the first transmission member 51 can be connected to the rotating assembly 30, the first transmission member 51 can be provided with a first threaded portion 5111, the second transmission member 52 can be rotatably installed on the supporting assembly 10, and the second transmission member 52 is provided with a second threaded portion 5211 that can cooperate with the first threaded portion 5111. The helical transmission connection between the first transmission member 51 and the second transmission member 52 is achieved by the cooperation between the first threaded portion 5111 of the first transmission member 51 and the second threaded portion 5211 of the second transmission member 52.

[0046] In the specific implementations provided in the present disclosure, the first transmission member 51 and the second transmission member 52 can be constructed in any suitable manner.

The helical transmission connection between the screw rod 511 and the screw sleeve 521 can effectively prevent the instantaneous displacement between the first transmission member 51 and the second transmission member 52 while ensuring the relative movement between the first transmission member 51 and the second transmission member 52, that is, while ensuring the relative movement between the support assembly 10 and the base assembly 40, the instantaneous displacement between the first transmission member 51 and the second transmission member 52 is effectively prevented, so as to effectively improve the reliability and stability of the folding structure. Figures 2 to 9 As shown, the first transmission member 51 may be a screw rod 511 , and the second transmission member 52 may be a threaded sleeve 521 ; the support assembly 10 includes a support body 1 , on which a first mounting portion 111 is disposed, and the threaded sleeve 521 is mounted in the first mounting portion 111 .

Each roller 532 sequentially passes through the corresponding through hole 5312 on each support 5311 to be mounted in the roller mounting hole. Since a spacing is provided between two adjacent supports 5311, it is convenient for the roller 532 to contact the outer wall of the screw sleeve 521 and the inner wall of the first mounting portion 111 when rotating, thereby realizing the rotation of the screw sleeve 521 in the first mounting portion 111, that is, the screw sleeve 521 can rotate relative to the support body 1.
