The transmission mechanism of the afs module of the automobile headlight

Abstract

The invention relates to a transmission mechanism of an AFS of an automobile front light. The transmission mechanism of the AFS of the automobile front light comprises a lighting unit, a U-shaped rotating frame, a horizontal rotating motor and a vertical dimming motor, wherein bearings are fixed at the U ends of the rotating frame, a first vertical rotating shaft and a second rotating shaft are installed on the bearings respectively, the first vertical rotating shaft and the second rotating shaft are fixed on the left end and the right end of a baffle of the lighting unit respectively, the output shaft of the horizontal rotating motor is connected with the bottom of the rotating frame, a supporting shaft is connected with a shell body through a supporting bearing, the top of the supporting shaft is connected with the enclosure of the horizontal rotating motor, the horizontal rotating motor is in movable connection with the top of a baffle component of the lighting unit, one end of a vertical power rod is connected with a horizontal rotating shaft, the other end of the vertical power rod is connected with the output end of the vertical dimming motor, and a second manual dimming mechanism installed on the shell body is connected with the vertical dimming motor. The transmission mechanism of the AFS of the automobile front light is simple and reasonable in structure and capable of improving shake proofing performance on the premise that the function of automobile light rotary dimming is satisfied.

Description

technical field [0001] The invention relates to a transmission mechanism of an AFS module of an automobile headlight, belonging to the technical field of vehicle lighting. Background technique [0002] The Adaptive Front-Lighting System module refers to a headlight system module that automatically changes more than two light patterns to adapt to changes in vehicle driving conditions. It can rotate the headlights of the vehicle in the horizontal direction according to the change of the vehicle's steering; at the same time, it can slightly adjust the beam of the headlights in the vertical direction to compensate for the inclination of the vehicle relative to the road surface. Variety. Such beams provide the best and safest illumination of the road ahead, significantly improving the driver's visibility of the road when cornering. [0003] Regulations require that any mechanical, electromechanical or other device in the AFS module combined with the lighting unit and used to co...

Problems solved by technology

The AFS module of the existing structure realizes the rotating dimming function, but because the rotating frame 2 is a cantilever beam structure, the lighting unit connected to the rotating frame 2 and the horizontal rotating motor 9 are all located at the lower part of the rotating center of the rotating frame 2, although the AFS module structure The middle and lower parts are small in size but heavy and concentrated, and there is no support at the bottom of the AFS module, so the force on the AFS module is unbalanced. Vibration and vibration not only reduce the working accuracy of the transmission mechanism, but also increase the wear of the interconnected parts of the transmission mechanism, resulting in the defects of light-shape jitter and light-shape instability
