Abstract

The invention discloses an automobile headlamp dimming device and a control method. The automobile headlamp dimming device comprises a shell (1) and a shell cover (2), and the shell cover (2) is connected to an opening of the shell (1); the device is characterized in that a stepping motor (3) is arranged in the shell (1), and a ball head assembly is arranged on the shell (1); a screw rod (301) is arranged on an output shaft of the stepping motor (3), the ball head assembly comprises a driving gear (6), and the screw rod (301) is meshed with the driving gear (6); the stepping motor (3) is started, under the action of the screw rod (301) and the driving gear (6), the stepping motor (3) can drive the ball head of the ball head assembly to move, and therefore the angle of the automobile headlamp is adjusted. According to the automobile headlamp dimming device and the control method, the structure is simple, intelligent control can be achieved, and gear adjustment is more refined.

Description

technical field [0001] The invention relates to the technical field of dimming motors for automobiles, in particular to an automobile headlight dimming device and a control method thereof. Background technique [0002] The function of the dimming motor is used in the headlights of the car. The function of the dimming motor is to adjust the direction of the headlights from the deviation direction to the standard direction, thereby improving the lighting effect of the headlights. The headlights of the car are in the trunk. Under the influence of time vibration, high and low road conditions, etc., the irradiation direction will deviate from the standard direction. The function of the dimming motor is to adjust the headlight irradiation direction from the deviated direction to the standard direction, thereby improving the lighting effect of the headlights. The automotive headlight dimming device in the prior art is controlled by a DC motor, and the gear position of the DC motor ...
