Description

Technical Field

[0001] The utility model relates to a waterproof sealing structure for a vehicle lamp, belonging to the technical field of automobile lamps. Background Art

[0002] Car lights are important safety equipment during driving, mainly including two categories: lighting and signal lights. Lighting is used to provide enough light to illuminate the road and objects in front of the driver, while signal lights are used to convey driving intentions and warn other road users of dangers.

[0003] A Chinese public patent (publication number: CN 218671850 U) discloses a sealing structure for a car lamp with heat dissipation, including a first shell installed in the car body, a lamp body installed in the first shell, a second shell for installing a circuit structure is provided on the side of the first shell away from the lamp body, a sealing shell for sealing the car lamp is provided on the side of the first shell away from the second shell, and a limit assembly for disassembly and assembly is provided on the sealing shell. The two moving blocks are driven to approach each other, and the spring is stretched at the same time, and the two limit plates are brought close to each other, and then the two limit plates are inserted into the limit grooves, the lever is released, the spring is deformed, and the spring pulls the two moving blocks to move toward both sides under the sliding of the slider, so that the two limit plates are respectively engaged in the limit grooves, thereby completing the installation of the sealing plate. The overall structure is simple, which is convenient for quick disassembly and assembly of the sealing plate, and the heat dissipation groove on the outside of the second shell can be used to dissipate the heat of the lamp body in time;

[0004] The above patent uses the second shell to move the lever toward the middle of the groove, so that the two sliders are close to each other in the slide groove, driving the two moving blocks to approach each other, and at the same time stretching the spring to make the two limit plates close to each other, and then inserting the two limit plates into the limit grooves, releasing the lever, and the spring deforming. The spring pulls the two moving blocks to move toward both sides under the sliding of the slider, so that the two limit plates are respectively engaged in the limit grooves, thereby completing the installation of the sealing plate. However, since the headlights are usually installed on the surface of the vehicle body, a certain degree of vibration will be generated with the movement of the vehicle body. The above patent only fixes the sealing plate through the cooperation of the spring, the limit plate and the limit groove. After the vehicle body vibrates for a long time, the sealing plate may become loose, causing the sealing plate to be unfixed, which greatly reduces the sealing performance of the headlights.

[0005] Therefore, a waterproof sealing structure for a vehicle lamp is proposed. Utility Model Content
