Technical Field

[0001] The utility model relates to the technical field of vehicle lamp adjusting fasteners, in particular to a vehicle lamp dimming flexible shaft. Background Art

[0002] Automobile lights are important functional parts of automobiles, and the role of high and low beams in the front combination lights of automobiles is an important part of the active safety of automobiles. While ensuring that the lights illuminate the road ahead, they must also ensure that they do not cause glare to oncoming vehicles. Mechanical dimming of high and low beams and front fog lights is a regulatory requirement. Most of the existing dimming equipment is a dimming screw from the rear of the lamp. Due to the limited space inside the lamp and the influence of the lamp housing, the direction and position of the dimming screw are fixed, resulting in large limitations on the dimming of the lamp. In addition, when installing and using the screw mechanism, it is often inconvenient to connect and fix the dimming screw due to limited space. In addition, the dimming screw is prone to damage after long-term use and is not easy to replace due to limited space.
