Description

Technical Field

[0001] The utility model relates to the technical field of automobile headlights, in particular to an automobile headlight assembly with adjustable light. Background Technique

[0002] The front headlights of a vehicle include a lamp cover, a lamp group, and a bottom shell. The lamp group is located between the lamp cover and the bottom shell, and the lamp group is generally fixed on the bottom shell, and then the bottom shell is fixedly connected to the vehicle body. The front headlights of the prior art can only adjust the high and low beams and cannot adjust the entire lamp group left and right. Therefore, the front headlights of the prior art cannot meet the multi-directional illumination requirements during illumination.

[0003] The prior art CN217763284U proposes an adjustable automobile headlight. By providing a first adjustment hole and a second adjustment hole on the bottom shell, and then providing a first mating hole and a second mating hole on the headlight assembly, and the lamp housing and the lamp holder are movably connected through a support assembly.

[0004] However, this device still has certain defects during actual use. With the increase of components in the assembly, the load on the solenoid valve is greater, and the air circulation is worse.

If the heat dissipation is not timely, in severe cases, the lighting assembly will be burned out, affecting driving safety.

[0005] Based on this, an automobile headlight assembly with adjustable light is now provided, which can eliminate the disadvantages of the existing device. Content of the Utility Model
