Automobile dimming device

Abstract

The invention relates to the field of automobile lamp fittings, in particular to an automobile dimming device. The automobile dimming device comprises a steering control module (10) which is used for controlling the steering of a motor (2), and an inching switch (11) which is used for manually controlling the on-off of a power supply of the motor (2); two conductive shrapnels (12) are also fixed on a second gear (6), and are mutually electrically connected; two turns of conductive materials (13) are also arranged on a circuit board (9); the two conductive shrapnels (12) and the two turns of conductive materials (13) are in contact one by one; a gap (14) is also arranged on one of the two turns of conductive materials (13); and the width of the gap (14) is more than the width of the contact position between each conductive shrapnel (12) and each conductive material (13). The automobile dimming device is low in cost and easy to popularize and sell.

Description

technical field [0001] The invention relates to the field of automobile lamp accessories, in particular to an automobile dimming device. Background technique [0002] The car dimming device is generally placed inside the headlight of the car. When the vehicle changes, the position of the light is adjusted by adjusting the reflector or lens of the headlight, thereby improving the safety lighting of the car. [0003] The dimming function of the automotive dimming device in the prior art is generally realized by sensors and control chips, that is, the number of turns of the motor is detected by the sensor, and then the control chip can calculate the number of turns of the motor according to the detected number of turns of the motor. The distance that the column moves is then controlled by the number of turns of the motor to achieve the purpose of dimming, but because the cost of the sensor and the control chip is high, the cost of the entire car dimming device will be high, wh...
