Abstract

The invention discloses a car headlamp follow-up steering arc driving system. The car headlamp follow-up steering arc driving system comprises a lamp body, an arc motor, a micro controller, a position sensor and a rotation shaft, wherein the rotation shaft is located at the circle center of the arc motor, the micro controller is connected with the arc motor and the position sensor through wires, and the rotation shaft is connected with the lamp body through a first support. The arc motor comprises an arc motor stator and an arc motor rotor, wherein one point of the center of the arc motor rotor is connected with an outer shell of the lamp body through a second support. The car headlamp follow-up steering arc driving system does not need gear transmission, and is simple in structure, high in reliability and low in cost.

Description

technical field [0001] The invention relates to an automobile headlight drive system, in particular to an automobile headlight follow-up steering arc drive system. Background technique [0002] Generally, car headlights have a certain lighting range regardless of the brightness. When turning at night or under poor light conditions, there will be a certain "blind spot" due to the problem of driving angle. In the case of fixed lighting, the blind spot is unavoidable, which affects driving safety to a certain extent. The light follow-up steering device can automatically adjust the steering angle of the headlights according to the driving speed and the steering angle of the vehicle body, so as to illuminate the "unreached" area in time, provide all-round safety lighting, and ensure the safety of turning at night. [0003] Patent application number 201220083167.5 "asynchronous control follow-up headlight system", application number 201220399526.8 patent "automatic follow-up head...
