Adjusting device for distance and passing light shapes of automobile head light

Abstract

The invention relates to an adjusting device for distance and passing light shapes of an automobile head light. The adjusting device comprises a fixing bracket, an adjusted component and an up, down, left and right (UDLR) adjusting mechanism; a passing light unit is arranged on the fixing bracket, and a distance light unit is arranged on the adjusted component; a cylindrical bore formed in the fixing bracket is matched with a fixed ball head arranged on the adjusted component; an elastic waist-hole groove formed in the fixing bracket is matched with a guide post arranged on the adjusted component; a through hole formed in the UDLR adjusting mechanism is matched with an adjusting rod arranged on the adjusted component, the UDLR adjusting mechanism adjusts the adjusted component to rotate up, down, left and right, so as to realize the adjustment of the distance and passing light shapes. The problem that because the distance light unit and the passing light unit of an existing adjusting device respectively belong to different brackets and adjusting systems, and after the illumination angle of the passing light unit is adjusted, the brightest light of the lighting light shape of the distance light is deviated from the passing light shape, is solved.

Description

technical field [0001] The invention relates to the technical field of automobile lamps, in particular to an adjustment device for lighting angles in automobile lamps, in particular to an adjustment device for far and near beam shapes of automobile headlamps. Background technique [0002] Car headlights are mainly used for lighting the car at night, and provide the best visual effect for the car during the driving process, which requires the lamp to have the best lighting effect. When the car is driving at night, when all the headlights are turned on at the same time for lighting, the lamps and lanterns should have the performance to enable the driver to see the traffic obstacles within 100 meters ahead, the lighting beam is aimed at the forward direction of the car, and the main optical axis The direction should be down. The quality of the far and near light shape and the direction of irradiation play an important role in the safe driving of the car at night. In the actual...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of this method is that the space size is large, because the high beam and low beam units each have a fixed bracket, and each bracket must be provided with a fixed fulcrum and two adjustment points that can be adjusted along the front and rear directions of the car. The distance between the fixed fulcrum and the two adjustable points is above 80mm

[0005] Another defect is that when the car light is installed on the frame, the low beam unit must be adjusted in the up, down, left, and right angles to meet the requirements of the regulations on the low beam irradiation angle.
