AI Technical Summary
During the assembly process, existing headlight ventilation caps are prone to the problem that the rubber bracket is removed from the plastic shell and is not assembled in place, resulting in an increased risk of headlight leakage.
A ventilation cap for automobile headlights is designed. By setting a limiting rib on the side wall of the rubber bracket and setting a limiting groove on the side wall of the shell, the positioning and installation of the rubber bracket is realized, and the installation stability is enhanced.
Through the design of limiting ribs and limiting grooves, the rubber bracket is ensured to be more in place and stable, reducing the possibility of the rubber bracket falling off from the shell and reducing the risk of headlights leaking.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle lamps, in particular to a ventilation cap used for vehicle lamps. Background Art
[0002] The main function of the headlight vent cap is ventilation and pressure balance, and it also has waterproof and dustproof functions. It balances the pressure difference inside and outside the headlight by ventilation, avoiding problems caused by excessive pressure difference, such as condensation of the headlight into fog. In addition, 通气帽 It can also effectively diffuse moisture and solve the problem of lens condensation, while blocking dust, dirt, road debris, splashing and spraying water to prevent them from entering the housing. These functions work together to ensure that the headlights can maintain good working condition under various environmental conditions and improve driving safety. The conventional breather cap is divided into three parts: plastic shell, waterproof membrane, and rubber bracket. The rubber bracket is interference fitted into the plastic shell, but this assembly method is prone to the problem of the rubber bracket detaching from the plastic shell and not being assembled in place.

[0003] In view of this, the purpose of the utility model is to provide a vent cap for a car lamp, optimize the vent cap assembly process, improve the assembly quality of the entire lamp, and reduce the risk of water leakage in the lamp.
[0004] The utility model provides a vent cap for automobile lamps using the following technical solutions:
[0005] A vent cap for a car lamp comprises a rubber bracket, a waterproof membrane and a shell for mounting the rubber bracket, wherein the waterproof membrane is arranged at the end of the rubber bracket and located inside the shell, a limiting rib is arranged on the side wall of the rubber bracket, and a limiting groove for inserting the limiting rib is arranged on the side wall of the shell.
[0006] Furthermore, a plurality of the limiting ribs are evenly arranged on the side wall of the rubber bracket, and a plurality of limiting grooves corresponding to the limiting ribs are arranged on the shell.
[0007] Furthermore, an anti-slip block is arranged on the side wall of the rubber bracket, and the limiting rib is arranged on the anti-slip block. When the rubber bracket is inserted into the shell, the anti-slip block abuts against the inner wall of the shell.
[0008] Furthermore, the anti-slip block is provided with anti-slip ribs, and when the rubber bracket is inserted into the shell, the anti-slip ribs abut against the inner wall of the shell.
[0009] Furthermore, two anti-slip ribs are provided on the anti-slip block, and the two anti-slip ribs are respectively located on both sides of the limiting rib.
[0010] To sum up, the utility model includes at least one of the following beneficial effects: when installing the rubber bracket, the limiting rib on the rubber bracket is inserted into the limiting groove on the shell, which can play a positioning role in the installation of the rubber bracket, and the assembly is more convenient. At the same time, the two sides of the limiting rib are in contact with the groove wall of the limiting groove, which can enhance the installation stability of the rubber bracket and reduce the possibility of the rubber bracket falling off from the shell.

[0015] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.
[0016] The following is combined with Figure 1-2 The utility model is described in further detail.
[0017] The utility model embodiment discloses a vent cap for automobile lamps. Figure 1-Figure 2 The vent cap for automobile lamps comprises a rubber bracket 1, a waterproof membrane 2 and a shell 3 for installing the rubber bracket 1. The waterproof membrane 2 is arranged at the end of the rubber bracket 1 and is located in the shell 3. The side wall of the rubber bracket 1 is provided with a limiting rib 11, and the side wall of the shell 3 is provided with a limiting groove 31 into which the limiting rib 11 is inserted. When installing the rubber bracket 1, the limiting rib 11 on the rubber bracket 1 is inserted into the limiting groove 31 on the shell 3, which can play a positioning role in the installation of the rubber bracket 1, and the assembly is more convenient. At the same time, the two sides of the limiting rib 11 abut against the groove wall of the limiting groove 31, which can strengthen the installation stability of the rubber bracket 1 and reduce the possibility of the rubber bracket 1 falling off from the shell 3.
[0018] In this embodiment, a plurality of limiting ribs 11 are evenly arranged on the side wall of the rubber bracket 1, and a plurality of limiting grooves 31 corresponding to the limiting ribs 11 are arranged on the shell 3. In this embodiment, there are three limiting ribs 11 and three limiting grooves 31, so that the rubber bracket 1 can be assembled more effectively and the stability of the rubber bracket can be enhanced.
[0019] In this embodiment, an anti-slip block 12 is provided on the side wall of the rubber bracket 1, and three anti-slip blocks 12 are provided. The limiting rib 11 is provided on the anti-slip block 12. When the rubber bracket 1 is inserted into the shell 3, the anti-slip block 12 abuts against the inner wall of the shell 3. After the rubber bracket 1 is inserted into the shell 3, the anti-slip block 12 pressurizes the inner wall of the shell 3, so that the rubber bracket 1 is more firmly inserted into the shell 3.
[0020] In this embodiment, an anti-slip rib 13 is provided on the anti-slip block 12. When the rubber bracket 1 is inserted into the shell 3, the anti-slip rib 13 abuts against the inner wall of the shell 3. The anti-slip rib 13 can further increase the tightness of the installation of the rubber bracket 1, making the rubber bracket 1 more firmly installed.
[0021] In this embodiment, two anti-slip ribs 13 are provided on the anti-slip block 12, and the two anti-slip ribs 13 are respectively located on both sides of the limiting rib 11. After the rubber bracket 1 is installed in the shell 3, the anti-slip ribs 13 on both sides of the limiting rib 11 are pressed against both sides of the limiting groove 31 to prevent the rubber bracket 1 from falling off from the shell 3.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
