Bearing light-modulation arrangement for automobile lamp

Abstract

The invention relates to a bearing dimming device of vehicle lights, which comprises an adjustment screw, a tabletting and a rear shell and characterized in that the outside of the adjustment screw is in close fit with a bearing. The inner ring of the bearing is in close fit with the adjustment screw, so is the outer ring with the rear shell. And the bearing is in permanent connection with the rear shell through a screw. Because the bearing adjustment is adopted, no friction is available between the adjustment screw and the rear shell and nor is the gap between the adjustment screw and the rear shell. On the way of the vehicle long-distance running, the phenomenon of loss or falling of mirror caused by the jolting of vehicle body does not occur. Moreover, because the bearing adjustment is adopted, the adjustment is more convenient and flexible.

Description

technical field [0001] The invention relates to an automobile part, in particular to an automobile lamp part, in particular to an automobile lamp bearing dimming device. Background technique [0002] Generally, the dimming structure used in lamps adopts the ordinary adjustment method of directly adjusting the dimming screw, but the reflector in this adjustment method is easy to jump in the lamp body, and it is because the adjusting screw and the back shell are perfectly matched by the plum blossom piece. , the friction between them is relatively large, and the resistance encountered by the reflector during dimming is relatively large, and it is easy to appear that the phenomenon of not being able to adjust during dimming will affect the qualified rate of the product. If it is a front combination lamp used on a heavy truck model, because the front combination lamp itself is relatively heavy and the working environment is relatively harsh, the body is bumpy, the reflector is e...

Problems solved by technology

[0002] Generally, the dimming structure used in lamps adopts the ordinary adjustment method of directly adjusting the dimming screw, and the reflector in this adjustment method is easy to jump in the lamp body, and it is because the adjusting screw and the back shell are perfectly matched by the plum blossom piece. , the friction between them is relatively large, and the resistance encountered by the reflector during dimming is relatively large, and it is easy to appear that the adjustment cannot be made during dimming, which will affect the qualified rate of the product

If it is a front combination lamp used on a heavy truck model, because the front combination lamp itself is relatively heavy and the working environment is relatively harsh, the body is bumpy, the reflector is easy to loosen in the lamp body, and the reflector may fall off, etc.
