[0040] An embodiment of the present application provides a snap-fit ​​structure for snap-fitting one component to another component.

[0041] like Figures 1 to 7 As shown, the clamping structure includes a buckle body 100 , a wedge block 200 and a clamping block 400 .

[0042] like Figure 1 As shown, the wedge block 200 is fixedly connected to the buckle body 100, and the two ends of the wedge block 200 are respectively a first end 220 and a second end 230, the thickness of the first end 220 is greater than the thickness of the second end 230, the first end 220 is close to the buckle body 100, and the second end 230 is far away from the buckle body 100, and the first end 220 and the second end 230 constitute a wedge block 200 with a gradually changing thickness.

[0043] For example, in some embodiments, the wedge block 200 is fixedly connected to the buckle body 100 by welding, gluing, bolting or integral molding.

[0044] like Figure 1 As shown, the clamping block 400 is fixedly connected to the buckle body 100. Figure 4 As shown, the first end 220 has a protruding structure, and the clamping block 400 is located on the buckle body 100 on a side of the protruding structure close to the wedge block 200, so that the first end 220 of the wedge block 200 and the clamping block 400 form a structure capable of clamping an object.

[0045] like Figure 6 As shown, the snap-fit ​​structure can be snap-fitted and connected with the snap-fit ​​housing 500, as shown in FIG. Figure 5 As shown, the snap-on housing 500 is a housing structure having a cavity inside. Figure 8 As shown, the snap-on housing 500 is snap-connected to the snap-on structure by means of a housing wall disposed at an edge.

[0046] like Figure 4 or Figure 8 As shown, a special space is formed between the first end of the wedge block and the clamping block, and this space can accurately accommodate the housing wall of the clamping housing. When the clamping block contacts the clamping housing, the clamping block will exert a force to push the clamping housing closer to the first end of the wedge block. This arrangement not only enhances the stability of the clamping connection, but also ensures a tight connection between the clamping housing and the wedge block.

[0047] The other side of the first end has the function of blocking the snap-on housing. When the snap-on housing is pushed toward the first end, the first end will effectively prevent it from falling out, thereby achieving the snap-on and locking of the snap-on housing. This locking mechanism ensures that the snap-on housing is not easy to fall off when subjected to external forces, greatly improving the stability of the structure.

[0048] It is worth noting that the thickness of the first end of the wedge block is greater than the thickness of the second end thereof. This design not only increases the thickness of the wedge block, but also improves its overall bearing capacity. When subjected to external pressure or impact, the thicker first end can more effectively disperse and resist these forces, thereby protecting the entire structure from damage.

[0049] In summary, the design of the wedge block fully demonstrates its strong clamping ability and stability. Through reasonable structure and layout, it realizes effective fixation and locking of the clamping shell, while improving the bearing capacity and durability of the structure.

[0050] Exemplarily, the snap body 100 is fixedly set on a preset object, for example, the preset object is a shading cover of a vehicle-mounted camera, and the snap-on shell 500 serves as a containing shell of the vehicle-mounted camera. The shading cover is snap-connected to the containing shell of the vehicle-mounted camera - the snap-on shell 500 through a snap-on structure.

[0051] Exemplarily, the preset object can also be a fixed frame, the snap body 100 is fixedly arranged on the fixed frame, and the snap-on shell 500 is a drawer box that can be pulled out. The box wall of the drawer box is snapped into the space formed between the wedge block 200 and the snap-on block 400, so that the position of the drawer box can be locked. When a large force is applied, the drawer box can be detached from between the wedge block 200 and the snap-on block 400 to unlock the position of the drawer box.
