[0028] Next, the embodiments of this specification will be described in detail.

[0029] In an electrical system, the waterproof performance of a wire harness is extremely important for stability. Taking a vehicle as an example, due to the relatively complex environment of the vehicle, the wire harness located in the wet area is easily invaded by moisture, resulting in the failure of the electrical system. At present, the structure of existing waterproof components is relatively complex, difficult to install, and has poor waterproof effects. This application provides a waterproof component and a vehicle to solve related technical problems.

[0030] As Figure 1 shown, this application provides a waterproof component, including a first waterproof shell 10 and a second waterproof shell 20. As Figure 2 and Figure 3 shown, the first waterproof shell 10 includes a first docking end 11. The first docking end 11 is provided with a first opening 12. The first waterproof shell 10 is provided with a first wire inlet 13 communicating with a waterproof space 30.

[0031] As Figure 4 and Figure 5 shown, the second waterproof shell 20 includes a second docking end 21. The second docking end 21 is connected to the first docking end 11, and the second docking end 21 is provided with a second opening 22. The first opening 12 and the second opening 22 are in sealing and mating alignment to enclose the waterproof space 30 with the first waterproof shell 10 and the second waterproof shell 20. The second waterproof shell 20 is provided with a second wire inlet 23 communicating with the waterproof space 30. The wire harness can extend into the waterproof space 30 through the first wire inlet 13 and the second wire inlet 23. The sizes of the first wire inlet 13 and the second wire inlet 23 match the size of the wire harness.

[0032] The waterproof component of this application is convenient to install and has good waterproof effects at the same time. When the first docking end 11 is connected to the second docking end 21, the waterproof space 30 can be formed, with a simple structure and convenient installation. Through the sealing and mating of the first opening 12 and the second opening 22, the sealing performance of the waterproof component is improved, and the waterproof effect is improved.

[0033] The waterproof component of this application can be applied to the connection of plugs. The first wire inlet 13 is used to pass through a first wire harness 60. The second wire inlet 23 is used to pass through a second wire harness 70. As Figure 1 shown, during use, the first wire harness 60 with a first plug 61 passes through the first wire inlet 13, and the second wire harness 70 with a second plug 71 passes through the second wire inlet 23. After the first plug 61 and the second plug 71 are plugged in, the first docking end 11 is connected to the docking end 21, and the first opening 12 and the second opening 22 are in sealing cooperation to prevent moisture from entering. The specific application field of the waterproof component is not limited.

[0034] The connection method between the first docking end 11 and the second docking end 21 is not limited. In one embodiment, the end face of the first docking end 11 can be abutted and fixed with the end face of the second docking end 21, and the sealing cooperation between the first opening 12 and the second opening 22 is achieved through the connection of the end faces. During installation, the first docking end 11 and the second docking end 21 can be aligned and abutted, which further improves the installation convenience of the waterproof component. In this embodiment, a corresponding snap-on structure or adhesive structure can be set on the end faces of the first docking end 11 and the second docking end 21 to achieve connection.

[0035] There is no limitation on the way to achieve sealing cooperation between the first opening 12 and the second opening 22. For example, a sealing ring may be provided at the connection between the first docking end 11 and the second docking end 21, or a sealing adhesive may be provided at the connection between the first docking end 11 and the second docking end 21. In one embodiment, the first docking end 11 may be sealed with the inner wall of the second opening 22. The second waterproof shell 20 wraps the first docking end 11 inside, so that the first opening 12 and the second opening 22 are sealed, thereby improving the sealing effect of the waterproof component and enhancing the waterproof performance. At the same time, the installation process of the waterproof component is simplified, and the first waterproof shell 10 can be inserted into the second waterproof shell 20 to complete the assembly.

[0036] The structures of the first waterproof shell 10 and the second waterproof shell 20 are not limited. Figure 2 and Figure 3 As shown, the first waterproof shell 10 may be barrel-shaped, and may include a main body 40 and a wire inlet pipe 50. The first docking end 11 is disposed on the main body 40. The first wire inlet port 13 is disposed on the wire inlet pipe 50. The wire inlet pipe 50 is formed by protruding from the main body 40 in a direction away from the main body 40. By providing the wire inlet pipe 50, during installation, the wire harness can pass through the wire inlet pipe 50 and extend into the first waterproof shell 10, so as to further improve the installation efficiency.

[0037] The structures of the first waterproof shell 10 and the second waterproof shell 20 may be the same or different. Figure 4 and Figure 5 As shown, the second waterproof shell 20 may also be barrel-shaped, and may also include a main body 40 and a wire inlet pipe 50. The second docking end 21 is disposed on the main body 40. The second wire inlet 23 is disposed on the wire inlet pipe 50. The wire inlet pipe 50 is formed by protruding from the main body 40 in a direction away from the main body 40.

[0038] In one embodiment, the first opening 12 and the first wire inlet 13 can be respectively disposed at two ends of the first waterproof shell 10. The second opening 22 and the second wire inlet 23 can also be respectively disposed at two ends of the second waterproof shell 20. The wire harness is inserted into the waterproof assembly in a straight line to prevent bending and improve the stability of the wire harness. In this embodiment, the wire inlet tube 50 can be formed by protruding from the side of the main body 40 away from the first opening 12.

[0039] In one embodiment, as Figure 2 and Figure 3 shown, the first docking end 11 may be provided with an external thread (not shown in the figure). As Figure 5 shown, the inner wall of the second opening 22 may be provided with an internal thread structure 221 that cooperates with the external thread structure 111. By means of the thread structure, the connection between the first docking end 11 and the second docking end 21 is realized, which not only ensures the simplicity of installation but also improves the installation reliability.

[0040] In this embodiment, as Figure 2 shown, the first docking end 11 may radially protrude to form a stepped structure 14, and the external thread structure 111 is arranged on the stepped structure 14. By forming the stepped structure 14, the size of the first docking end 11 can be increased, the tightness of the connection between the first docking end 11 and the second opening 22 can be improved, the sealing performance of the waterproof component can be enhanced, and the waterproof effect can be further improved.

[0041] In one embodiment, at least one of the first docking end 11 and the second docking end 21 may be made of an elastic material, and the first docking end 11 elastically abuts against the inner wall of the second opening 22. Through the elastic abutment, the sealing fit between the first opening 12 and the second opening 22 is realized, further improving the simplicity of installation. The elastic material can be rubber, silica gel, foam, etc., and the specific material type is not limited.

[0042] Specifically, one of the first docking end 11 and the second docking end 21 may be made of an elastic material and the other may be made of a rigid material. The rigid material can serve as a non-deformable reference during installation to improve the assembly efficiency. The first docking end 11 and the second docking end 21 may also both be made of an elastic material, which can enhance the sealing performance. When the waterproof component is impacted, multiple elastic components can provide buffering to prevent the first docking end 11 and the second docking end 21 from separating after being impacted.

[0043] The first waterproof shell 10 and the second waterproof shell 20 may be entirely made of an elastic material, which is convenient for manufacturing. Only the first docking end 11 of the first waterproof shell 10 may also be made of an elastic material. Only the second docking end 21 of the second waterproof shell 20 may also be made of an elastic material.

[0044] In one embodiment, as Figure 1 shown, the second waterproof shell 20 may include a bottom wall 24. The bottom wall 24 is located on the side facing the waterproof space 30 and is disposed opposite to the first docking end 11. There is a gap between the first docking end 11 and the bottom wall 24. The first docking end 11 does not extend into the bottommost part of the second waterproof shell 20, increasing the volume of the waterproof space 30, broadening the application range of the waterproof component, and allowing a larger wire harness to be installed into the waterproof space 30.

[0045] The inner wall of the inlet pipe 50 may be provided with a threaded structure (not shown in the figure) or a serrated structure (not shown in the figure). Since the wire harness is usually wrapped with a corrugated pipe, and the corrugated pipe is provided with a threaded structure or a serrated structure, by providing a threaded structure or a serrated structure on the inner wall of the inlet pipe 50, the structure of the inlet pipe 50 is matched with that of the corrugated pipe, improving the fitting degree of the inlet pipe 50 and the wire harness and the sealing performance, and further enhancing the waterproof effect of the waterproof component.

[0046] The present application also provides a vehicle, including a first wire harness 60, a second wire harness 70, and the above-mentioned waterproof component. The first wire harness 60 passes through the first inlet 13, and the second wire harness 70 passes through the second inlet 23. The first wire harness 60 and the second wire harness 70 are connected within the waterproof space 30. Since the waterproof component of the present application has high installation efficiency and good waterproof effect, the vehicle of the present application has high production efficiency and good stability of the circuit system. The type of the vehicle of the present application is not limited, and it can be a fuel vehicle, a hybrid vehicle, an electric vehicle, etc.

[0047] In one embodiment, the first wire harness 60 may be elastically abutted against the inner wall of the first inlet 13, and the second wire harness 70 may be elastically abutted against the inner wall of the second inlet 23. The first inlet 13 and the second inlet 23 may both be elastically abutted against the wire harness, or one of them may be elastically abutted against the wire harness. By means of elastic abutment to achieve interference fit, the sealing performance can be improved, the waterproof effect of the waterproof component can be further enhanced, and the stability of the electrical system of the vehicle can be improved.

[0048] The method for realizing the elastic abutment between the wire harness and the inlet is not limited. In one embodiment, the first waterproof shell 10 and the second waterproof shell 20 may be integrally made of an elastic material such as rubber. Only the area where the first inlet 13 is provided on the first waterproof shell 10 may be made of an elastic material. Only the area where the second inlet 23 is provided on the second waterproof shell 20 may also be made of an elastic material.

[0049] The waterproof component of the present application can be applied to the plug connection of a vehicle. As Figure 1 shown, the first wire harness 60 may include a first plug 61 and a first wire harness main body 62. The second wire harness 70 may include a second plug 71 and a second wire harness main body 72. The first wire harness main body 62 passes through the first inlet 13, and the second wire harness main body 72 passes through the second inlet 23. The first plug 61 and the second plug 71 are connected within the waterproof space 30.

[0050] The above are only the preferred embodiments of the present application and do not impose any formal restrictions on the present application. Moreover, the above embodiments can complement each other without conflict. Although the present application has been disclosed above in the preferred embodiments, it is not intended to limit the present application.
