Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamps, in particular to a dimming component structure. Background Art

[0002] The dimming structure of vehicle lights on the market generally consists of a dimming gear and a dimming screw installed on the shell. The dimming gear and the dimming screw are threadedly engaged in the manner of a bevel gear. Rotating the dimming gear synchronously drives the dimming screw to rotate. During the rotation of the dimming screw, the corresponding mechanism is driven to move to achieve dimming. The defect is that the dimming component has only one adjustment direction drive, resulting in a single adjustment direction, causing the dimming of the entire vehicle or the dimming of the lamp at the factory to be restricted by the adjustment direction, resulting in inconvenience in dimming.

[0003] In addition, the shells that carry the dimming gears and dimming screws are mostly split-assembly molding structures, which are more troublesome to assemble. The common dimming structure installation methods on the market are snap-on fixation or interference fit fixation. The parts are complicated to assemble and difficult to disassemble, and the parts are easily damaged, which needs to be improved. Utility Model Content
