Technical Field

[0001] The present invention relates to the technical field of waterproofing of electrical components, and in particular to a waterproof housing of electrical components and a vehicle. Background Art

[0002] When assembling precision electrical components in the wet area of ​​the vehicle, it is necessary to meet the waterproof requirements of the wet area environment. At the same time, the waterproof performance of the components must not be reduced during the disassembly and assembly process.

[0003] Currently, electrical components are typically installed by encapsulating the circuit boards with glue to create a seal. The components are then clipped onto the component housing and attached to the vehicle's interior structure. This simple installation method can be challenging to disassemble during repairs. Because the clips on the component housing typically have an interference fit with the vehicle's interior structure, disassembly requires inserting a flat-head tool like a screwdriver into the gap to pry the housing and interior structure apart. This can be time-consuming, and repeated disassembly can compromise the electrical component's waterproofing, posing a significant safety risk.

[0004] Therefore, there is an urgent need to provide a waterproof housing for electrical components and a vehicle to solve the above problems. Summary of the Invention

[0005] According to one aspect of the present invention, a waterproof housing for an electrical component is provided, which has a simple structure and can not only provide waterproof protection for the electrical component but also prevent damage to the electrical component when the electrical component is disassembled.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] The waterproof shell of the electrical component is applicable to the electrical component, wherein the electrical component comprises an outer shell, and the waterproof shell of the electrical component comprises a sleeve shell.

[0012] Optionally, a diameter of the first positioning hole is greater than a diameter of the first positioning column, and a width of the second positioning hole is greater than the diameter of the second positioning hole.

[0013] Optionally, there are multiple card slots, and the multiple card slots are arranged at intervals along the circumference of the shell.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0036] The present invention provides a waterproof housing for an electrical component, which has a simple structure, can protect the electrical component, and is convenient for installation and removal between the electrical component and the interior structure of a vehicle body.

[0037] Specifically, if Figure 1-7As shown, the waterproof housing for electrical components is used to protect the electrical components and provide waterproofing. The electrical components include a housing 100 and a casing 200. The casing 200 can be mounted outside the housing 100, integrating the casing 200 with the electrical components. Specifically, the bottom wall of the casing 200 is provided with a positioning hole, and the bottom wall of the housing 100 is provided with a positioning post. The positioning post can be plugged into the positioning hole. The plugging of the positioning hole and the positioning post facilitates the installation and positioning of the electrical components and the casing 200. The side wall of the casing 200 is provided with a slot 220, and the side wall of the housing 100 is provided with an elastic clip 120. The elastic clip 120 can be plugged into the slot 220. The top of the side wall of the casing 200 is provided with a connecting portion 230, and the connecting portion 230 is provided with a connecting hole 231. A bolt passes through the connecting hole 231 and is threadedly connected to the vehicle body interior structure. By providing elastic clips 120 for engagement with slots 220, the electrical component and its waterproof housing are integrated into one piece. Furthermore, by connecting the electrical component's waterproof housing to the vehicle interior structure, the electrical component is secured to the vehicle interior structure. Compared to the prior art method of directly connecting the electrical component housing 100 to the vehicle interior structure through a snap connection, this prevents damage to the electrical component during separation, thereby improving the electrical component's waterproof performance.

[0038] Further, see Figure 1-3 The bottom wall of the housing 200 is provided with an avoidance hole 240, and part of the housing 100 is sealed and penetrated in the avoidance hole 240. The position and number of the avoidance holes 240 can be set according to the structure of the housing 100 of the electrical component.

[0039] Preferably, to enhance the connection strength between the casing 200 and the vehicle interior structure, and thereby improve the reliability of the fixed electrical components, a plurality of connecting portions 230 are provided on the casing 200. The connecting portions 230 are spaced apart along the circumference of the casing 200. In this embodiment, three connecting portions 230 are provided, and the connecting portions 230 are perpendicular to the sidewalls of the casing 200. In other embodiments, the number and arrangement of the connecting portions 230 may be different, depending on the specific configuration of the vehicle interior structure.

[0040] Preferably, if Figure 2-6 As shown, the head of the positioning post is truncated cone-shaped, which makes it easier to insert the positioning post into the positioning hole, facilitating the installation of the electrical component and the housing 200. Optionally, the angle b between the busbar of the truncated cone and the horizontal plane can be set according to actual needs. In this embodiment, the angle b is 63.43°. The diameter a and height c of the positioning post can be set according to actual needs. In this embodiment, the diameter a of the positioning post is 2.5 mm, and the height c is 2.8 mm. Of course, in other embodiments, the dimensions of the positioning post can also be other, and can be set according to actual needs.

[0041] Furthermore, the positioning posts include a first positioning post 111 and a second positioning post 112, and the positioning holes include a first positioning hole 211 and a second positioning hole 212. The first positioning post 111 is plugged into the first positioning hole 211, and the second positioning post 112 is plugged into the second positioning hole 212. The first positioning hole 211 is a round hole, and the second positioning hole 212 is a waist-shaped hole. The length direction of the waist-shaped hole is the same as the direction of the line connecting the first positioning hole 211 and the second positioning hole 212. By setting the second positioning hole 212 as a waist-shaped hole, the installation freedom of the first positioning post 111 and the second positioning post 112 can be increased, and the risk of the electrical component and the housing 200 being unable to be installed due to manufacturing errors of the first positioning post 111 and the second positioning post 112 is reduced.

[0042] Preferably, the diameter of the first positioning hole 211 is larger than the diameter of the first positioning post 111, so that the first positioning post 111 and the first positioning hole 211 are plugged in. The width of the second positioning hole 212 is larger than the diameter of the second positioning post 112, so that the second positioning post 112 and the second positioning hole 212 are plugged in. In this embodiment, Figure 5 As shown, the diameter f of the first positioning hole 211 is 2.6 mm, the width of the second positioning hole 212 is 2.6 mm, and the length of the second positioning hole 212 (d+2e, where e is the radius of the arc) is 3.5 mm. Of course, in other embodiments, the dimensions of the first positioning hole 211 and the second positioning hole 212 can also be other, and can be set according to actual needs.

[0043] Preferably, the positioning hole is funnel-shaped, and the wide end of the positioning hole is close to the positioning post, so as to facilitate the insertion of the positioning post into the positioning hole.

[0044] Furthermore, a plurality of slots 220 are provided, and the plurality of slots 220 are spaced apart along the circumference of the housing 200. By providing a plurality of slots 220, the connection strength between the electrical component and the housing 200 can be improved. Figure 7 As shown, after the slot 220 is engaged with the elastic buckle 120, a gap is provided between the elastic buckle 120 and the slot 220, facilitating the engagement of the elastic buckle 120 with the slot 220. In this embodiment, the width h of the slot 220 is 13.8 mm, and the width i of the elastic buckle 120 is 12 mm. Of course, in other embodiments, the widths of the elastic buckle 120 and the slot 220 can be adjusted according to actual needs.

[0045] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention.
