The embodiments described below by reference to the drawings are exemplary only, and are used to explain the present application, and should not be understood as a limitation of the present application.

[0032] Reference will be made to Figures 1-3 A clamping structure 100 according to an embodiment of the present application is described below.

[0033] According to the clamping structure 100 of the first aspect of the present application, referring to Figures 1-3 for mounting the fixed module 10 to the mounting seat 20, the clamping structure 100 comprises: a Z-direction support table 21, a Z-direction limiting structure 23, an X-direction limiting structure 27, a Y-direction limiting structure 29 and a Y-direction elastic limiting structure 30 provided on the mounting seat 20.

The mounting seat 20 comprises a first end 33 and a second end 34 arranged opposite along the Y-direction, and the fixed module 10 is adapted to slide to the mounting position along the direction from the first end 33 to the second end 34 and adapted to slide out of the mounting position along the direction from the second end 34 to the first end 33.

[0035] The Y-direction elastic limiting structure 30 can be elastically deformed in the Z-direction to avoid a sliding space for the fixed module 10 to slide in the Y-direction, and in the process of the fixed module 10 sliding in the Y-direction to the mounting position, the fixed module 10 is adapted to pass over the Y-direction elastic limiting structure 30 in the Y-direction and adapted to extrude the Y-direction elastic limiting structure 30 in the Z-direction.

[0036] When the fixed module 10 is installed on the mounting base 20, the fixed module 10 is first placed on the Z-direction support table 21 for supporting the fixed module 10 upward in the Z-direction, at this time, the X-direction limiting structure 27 limits the fixed module 10 in the X-direction, and the fixed module 10 is in the first position; then the fixed module 10 is pushed in the direction from the first end 33 to the second end 34, and the fixed module 10 is moved along the Y-direction to pass the Y-direction elastic limiting structure 30 while extruding the Y-direction elastic limiting structure 30 downward in the Z-direction, so that the fixed module 10 can move in the Y-direction, when the fixed module 10 slides to the installation position, the fixed module 10 no longer extrudes the Y-direction elastic limiting structure 30, the Y-direction elastic limiting structure 30 is bounced upward and plays a limiting role in the Y-direction on the fixed module 10; the side of the fixed module 10 close to the second end 34 is in abutment with the Y-direction limiting structure 29 in the Y-direction, preventing the fixed module 10 from sliding excessively; and the Z-direction limiting structure 23 limits the fixed module 10 upward in the Z-direction.

[0037] When the fixed module 10 is detached from the mounting base 20, the user presses the Y-direction elastic limiting structure 30 downward in the Z-direction, so that the Y-direction elastic limiting structure 30 no longer limits the fixed module 10 in the Y-direction, and then the fixed module 10 is pushed in the direction from the second end 34 to the first end, the fixed module 10 extrudes the Y-direction elastic limiting structure 30 to move, and gradually separates from the limiting of the Y-direction limiting structure 29 and the Z-direction limiting structure 23 in the process, and is pushed to the first position, at this time, the fixed module 10 is only supported upward by the Z-direction support table 21, and the fixed module 10 is removed, that is, the fixed module 10 is detached from the mounting base 20.

[0039] According to some embodiments of the present application, refer to Figure 3The Y-direction limiting structure 29 is arranged at the second end 34, and the Y-direction limiting structure 29 is adapted to abut against one side of the fixing module 10 adjacent to the second end 34. The Y-direction elastic limiting structure 30 is arranged between the first end 33 and the second end 34. By arranging the Y-direction limiting structure 29 at the second end 34, when the fixing module 10 slides to the mounting position, the Y-direction limiting structure 29 abuts against one side of the fixing module 10 adjacent to the second end 34, which can prevent the fixing module 10 from sliding excessively, and can make the mounting seat 20 limit the fixing module 10 more fully, thereby improving the mounting precision.

[0040] According to some embodiments of the present application, referring to Figure 3 The mounting seat 20 is formed with a mounting opening 35, and the fixing module 10 is mounted in the mounting opening 35.

For example, the mounting seat 20 is formed with a mounting opening 35, and the fixing module 10 is mounted in the mounting opening 35. One end of the first limiting buckle 24 in the Y-direction is connected to the inner wall of the mounting opening 35. Since the fixing module 10 needs to be pushed in the direction from the first end 33 to the second end 34 when being mounted on the mounting seat 20, by making the other end of the first limiting buckle 24 in the Y-direction a free end and extending towards the direction close to the first end 33, the other end of the first limiting buckle 24 in the Y-direction can provide sufficient space for the movement of the fixing module 10 during installation.

By arranging the mounting protrusion 14 on the fixing module 10 and arranging at least part of each mounting protrusion 14 in the limiting space 25 defined by the corresponding first limiting press buckle 24 and the Z-direction supporting table 21, the fixing module 10 can be more easily limited by the limiting space 25, and the installation precision is improved. By arranging the first limiting press buckle 24 to have the elastic deformation ability in the Z-direction, the process of pushing the fixing module 10 in the direction from the first end 33 to the second end 34 is more convenient and labor-saving. By arranging the mounting protrusion 14 to be interference fit with the corresponding limiting space 25, the limiting space 25 can limit and fix the fixing module 10 in the Z-direction, the installation precision is improved, and the fixing module 10 is prevented from moving in the Z-direction.
