[0002] At present, a headlight dimming device that adjusts the pitch angle of the headlight is installed on the headlights of advanced cars, so as to meet the different requirements of the headlight irradiation angle when the vehicle goes up and downhill and under different driving conditions. The working principle of the angle is that a dimming drive device pulls or pushes the reflector in the headlight, so that the reflector rotates up and down around the horizontal horizontal axis to realize the illumination effect of the headlight light up and down. The current headlight The control and drive structure of the light dimming actuator is relatively simple, and there are disadvantages such as poor control accuracy, poor anti-interference ability, and large working noise during transmission.
