[0034] Embodiment 1

[0035] Please refer to Figures 1-5 , the present utility model provides a headlight, including a rubber bowl 12 and a lamp cover 11. The lamp cover 11 is fixedly connected to the rubber bowl 12 by ultrasonic welding. An installation chamber is formed between the rubber bowl 12 and the lamp cover 11, and the installation chamber is provided with:

[0036] A bottom cover 14, and the bottom cover 14 is fixed relative to the rubber bowl 12 and the lamp cover 11;

[0037] The light source circuit board 13 is fixed on the bottom cover 14, and the light source circuit board 13 is located between the lamp cover 11 and the bottom cover 14.

[0038] As a further solution, a first limiting ring 111 is integrally formed at one end of the lamp cover 11. The first limiting ring 111 is inserted into the rubber bowl 12. A second limiting ring 121 is integrally formed on the inner side wall of the rubber bowl 12. The first limiting ring 111 and the second limiting ring 121 cooperate with each other to install and fix the bottom cover 14.

[0039] In this solution, the first limiting ring 111 and the inner side wall of the rubber bowl 12 are fixed by ultrasonic welding. The vehicle lamp manufactured in this way has good appearance quality, excellent waterproof effect, and high connection strength.

[0040] It should be noted that the lamp cover 11 includes a lens and a housing arranged outside the lens. Among them, the first limiting ring 111 is arranged on the housing. Refer to Figure 2 Appendix Figure 3 It can be seen that in this embodiment, the lens and the housing are integrally formed. In this way, there is no need to use a corresponding connection structure to fix the lens, reducing the installation steps.

[0041] As a further solution, a third limiting ring 122 is integrally formed on the outer side wall of the rubber bowl 12. The lamp cover 11 and the third limiting ring 122 cooperate with each other to relatively fix the vehicle lamp on the installation structure. In this solution, a step surface is formed between the lamp cover 11 and the first limiting ring 111, and a stepped surface corresponding to it is formed between the third limiting ring 122 and the rubber bowl 12. The installation structure is clamped and fixed by two opposite annular planes. In this way, the vehicle lamp can be connected and fixed to the installation structure.

[0042] As a further solution, the light source circuit board 13 is bolted to the bottom cover 14. Specifically, a plurality of connecting pipes are arranged on the bottom cover 14. Threaded holes are opened on the inner walls of the connecting pipes. After the screws pass through the light source circuit board 13, they are threadedly connected to the connecting pipes to connect and fix the light source circuit board 13 to the bottom cover 14. In this solution, three connecting pipes are provided to ensure the fixing effect.

[0043] As a further solution, refer to Figure 5 , a plurality of support plates 142 are integrally formed on the side of the bottom cover 14 close to the light source circuit board 13. The light source circuit board 13 is in contact with the plurality of support plates 142; in the above solution, since the contact between the light source circuit board 13 and the bottom cover 14 is point contact, after being affected by an external force, the pressure borne by the contact point is relatively large. The support plates 142 can reduce the pressure borne per unit area and prevent the light source circuit board 13 from being damaged.

[0044] As a further preferred solution, a plurality of through grooves 141 are formed in the bottom cover 14. By providing the plurality of through grooves 141, on the one hand, materials can be saved and production costs can be reduced, and on the other hand, air circulation can be achieved to facilitate heat dissipation.

[0045] As a further preferred solution, a conduit 143 is provided on the bottom cover 14, a wire slot 131 is formed in the light source circuit board 13, and a rubber protective sleeve 15 is sleeved on the power line of the light source circuit board 13. The rubber protective sleeve 15 cooperates with the conduit 143 and the wire slot 131.

[0046] As a further solution, at least one positioning surface 144 is formed on the outer peripheral wall of the bottom cover 14, and a corresponding positioning plate is formed on the rubber bowl 12. After the bottom cover 14 is inserted into the rubber bowl 12, the positioning surface 144 and the positioning plate cooperate with each other to prevent the bottom cover 14 from rotating. In this way, it can be prevented that the rotation of the bottom cover 14 drives the power line of the light source circuit board 13 to rotate.

[0047] It should be noted that this structure can also be provided on the lamp cover 11 and / or the bottom cover 14 to prevent relative rotation between the lamp cover 11 and the bottom cover 14.
