Description

Technical Field

[0001] This utility model belongs to the field of vehicle body controller technology, specifically relating to a snap-fit ​​structure and a vehicle body controller. Background Technology

[0002] To save costs, vehicle body controllers are typically non-sealed. The controller consists of a housing and a circuit board, with the circuit board housed within the housing. The housing is divided into a first half-housing and a second half-housing. To ensure a certain level of waterproofing, the first and second half-housings are connected by an internal snap-fit ​​structure: the outer wall of the first half-housing has snaps, and the inner wall of the second half-housing has slots. During assembly, significant pressure is applied to compress the first half-housing inwards. As the first half-housing retracts, the snaps are positioned within the second half-housing. Releasing the pressure then allows the snaps to spring back into the slots within the second half-housing.

[0003] The disadvantages of the existing internal snap-fit ​​structure are that it requires a large pressing force from the tooling equipment, which makes disassembly and assembly difficult and causes a lot of noise during assembly. Utility Model Content

[0004] This invention provides a snap-fit ​​structure to solve the technical problem of excessive pressing force in the prior art.

[0005] This utility model is achieved through the following technical solution: a snap-fit ​​structure, including a side wall and a boss; the side wall has a thinned portion; the boss is disposed on the thinned portion.

[0006] The sidewalls are designed for waterproofing. The thinned sections on the sidewalls have lower rigidity than other parts, making them more susceptible to deformation under pressure. Furthermore, the thinned sections do not penetrate the sidewalls, ensuring the waterproofing of the sidewall structure. Bosses protrude from the sidewalls for snap-fitting. These bosses are located on the thinned sections, and when pressed, they are more easily displaced with the deformation of the thinned sections, thus reducing the required pressing force.

[0007] Furthermore, one side of the thinned portion is a flat surface, and the other side is a concave surface. The concave surface reduces the thickness of the thinned portion.

[0008] Furthermore, the recessed surface is a concave arc surface or a V-shaped surface.

[0009] Furthermore, one side of the thinned portion is a plane, and the other side is provided with a first groove. The thickness of the thinned portion is reduced by the first groove.

[0010] Furthermore, the boss is disposed on the plane of the thinned portion. This facilitates surface contact through the plane after the boss is engaged.

[0011] Furthermore, a second groove is provided on the boss. The second groove can reduce the rigidity of the boss, thereby further reducing the required pressing force.

[0012] Furthermore, the second groove is positioned directly opposite the thinnest point of the thinned portion. The thinned portion exhibits minimal stiffness and optimal deformation performance.

[0013] Furthermore, the depth of the second groove is equal to the height of the boss. The boss forms a segmented structure, which significantly reduces the stiffness of the boss, while avoiding the second groove being too deep and causing the thinned part to be too thin. If the thinned part is too thin, it is easy for perforation to occur during manufacturing or use, resulting in a decrease in waterproof performance.

[0014] This utility model also provides a vehicle body controller, including a first half-shell and a second half-shell. The first half-shell includes the above-mentioned snap-fit ​​structure, and the second half-shell is provided with a slot, into which the boss is snapped.

[0015] Furthermore, the boss is disposed on the outer surface of the side wall of the first half-shell, and the slot is disposed on the inner surface of the side wall of the second half-shell. This forms an internal snap-fit ​​structure and allows the use of existing tooling equipment.

[0016] Furthermore, the outer surface of the side wall of the second half-shell protrudes outward at the location corresponding to the slot. This locally enhances the strength of the second shell plate and compensates for the strength loss of the second half-shell due to the slot.

[0017] Furthermore, the inner surface of the sidewall of the first half-shell is provided with pressure posts offset from the thinned portion, and the bottom surface of the second half-shell is provided with a support post. A clamping gap for mounting the circuit board is formed between the pressure posts and the support post. The circuit board is mounted in the clamping gap, which is convenient for installation and saves installation space.

[0018] This invention can reduce assembly force without compromising waterproof performance, and has the advantages of easy assembly and disassembly and low installation noise. Attached Figure Description

[0027] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] To address the technical problem of excessive pressing force in existing technologies, this utility model provides a snap-fit ​​structure, including a side wall and a boss; the side wall has a thinned portion; the boss is disposed on the thinned portion.

[0029] The sidewalls are designed for waterproofing. The thinned sections on the sidewalls have lower rigidity than other parts, making them more susceptible to deformation under pressure. Furthermore, the thinned sections do not penetrate the sidewalls, ensuring the waterproofing of the sidewall structure. Bosses protrude from the sidewalls for snap-fitting. These bosses are located on the thinned sections, and when pressed, they are more easily displaced with the deformation of the thinned sections, thus reducing the required pressing force.

[0030] Example 1

[0031] In this embodiment, the thinning section is formed by setting grooves to reduce the sidewall thickness.

[0032] refer to Figure 1 and Figure 2 As shown, the snap-fit ​​structure provided in this embodiment includes a side wall 1 and a boss 102; the side wall 1 has a thinning portion; the boss 102 is disposed on the thinning portion, one side of the thinning portion is a plane, and the other side is provided with a first groove 101.

[0033] Preferably, the boss 102 is disposed on the plane of the thinned portion. This facilitates surface contact through the plane after the boss 102 is engaged.

[0034] Preferably, the boss 102 is provided with a second groove 1021. The second groove 1021 can reduce the rigidity of the boss 102 and further reduce the required pressing force.

[0035] Preferably, when the second groove 1021 is directly opposite the thinnest position of the thinned portion, that is, when the second groove 1021 is directly opposite the first groove, the thinned portion has the minimum stiffness and the best deformation effect.

[0036] Preferably, the depth of the second groove 1021 is equal to the height h of the boss 102. The boss 102 forms a segmented structure, which greatly reduces the rigidity of the boss 102. At the same time, it avoids the second groove 1021 from being too deep, which would cause the thinned part to be too thin. If the thinned part is too thin, it is easy to perforate during manufacturing or use, which would lead to a decrease in waterproof performance.

[0037] refer to Figure 3 As shown, this embodiment also provides a vehicle body controller, including a first half-shell 2 and a second half-shell 3. The first half-shell 2 includes the snap-fit ​​structure of this embodiment, and the second half-shell 3 is provided with a slot 301, and the boss 102 is snapped into the slot 301.

[0038] Preferably, the outer surface of the side wall of the second half-shell 3 protrudes outward at the portion 303 corresponding to the slot 301. This locally enhances the strength of the second half-shell 3 and compensates for the strength loss caused by the slot 301.

[0039] Preferably, the boss 102 is disposed on the outer surface of the side wall 1 of the first half-shell 2, and the slot 301 is disposed on the inner surface of the side wall of the second half-shell 3. This forms an internal snap-fit ​​structure and allows the use of existing tooling equipment.

[0040] refer to Figure 3 As shown, during assembly, the first half-shell 2 is first inserted into the second half-shell 3. The side wall of the first half-shell fits against the side wall of the second half-shell 3. However, the boss 102 on the first half-shell 2 protrudes outward from the second half-shell 3. Therefore, it is necessary to use the pressing force of the tooling equipment to press the boss 102 inward along the direction of the arrow in the figure. The boss 102 is set on the thinned part. When pressing the boss 102, the boss 102 is more likely to move with the deformation of the thinned part, thereby reducing the required pressing force.

[0041] refer to Figure 4 As shown, after the pressing force is removed, the boss 102 springs back into the slot 301 as the thinned part springs back.

[0042] refer to Figure 5As shown, preferably, the inner surface of the side wall of the first half-shell 2 is provided with a pressure post 201 that is offset from the thinned portion, and the bottom surface of the second half-shell 3 is provided with a support post 302. A clamping gap for mounting the circuit board is formed between the pressure post and the support post. The circuit board is mounted in the clamping gap, which is convenient for installation and saves installation space.

[0043] Example 2

[0044] In this embodiment, the thinning portion is formed by providing a recessed surface to reduce the sidewall thickness.

[0045] refer to Figure 6 As shown, this embodiment provides a snap-fit ​​structure, including a sidewall 1 and a boss 102; the sidewall has a thinned portion; the boss 102 is disposed on the thinned portion, one side of the thinned portion is a plane, and the other side is a recessed surface 103. The thickness of the thinned portion is reduced by the recessed surface 103.

[0046] In this embodiment, the recessed surface 103 is a concave arc surface or a V-shaped surface, or of course, it can be any other concave surface 103.

[0047] Preferably, the second groove 1021 is directly opposite the thinnest position of the thinned portion, that is, the second groove 1021 is directly opposite the deepest part of the concave surface 103, so that the thinned portion has the minimum rigidity and the best deformation effect.

[0048] refer to Figure 7 As shown, this embodiment also provides a vehicle body controller, including a first half-shell 2 and a second half-shell 3. The first half-shell 2 includes the snap-fit ​​structure of this embodiment, and the second half-shell 3 is provided with a slot 301, and the boss 102 is snapped into the slot 301.

[0049] Preferably, the outer surface of the side wall of the second half-shell 3 protrudes outward at the portion 303 corresponding to the slot 301. This locally enhances the strength of the second half-shell 3 and compensates for the strength loss caused by the slot 301.

[0050] Example 3

[0051] In both Embodiment 1 and Embodiment 2, the boss is set on the outer surface of the side wall of the first half-shell, and the slot is set on the inner surface of the side wall of the second half-shell.

[0052] In this embodiment, the snap-fit ​​structure of Embodiment 1 or Embodiment 2 is provided on the side wall of the second half-shell, and the boss is provided on the inner surface of the side wall of the second half-shell, and the first half-shell is provided with a slot for snapping the boss on the side wall.

[0053] During assembly, the second half-shell is expanded outward by the outward extrusion force, so that the first half-shell can be inserted into the second half-shell. After the extrusion force is released, the boss is snapped into the slot as the thinned part springs back.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
