Self-adaptive headlamp actuating mechanism

Abstract

The invention aims to provide a self-adaptive headlamp actuating mechanism which has the characteristics of simple structure, low cost, high accuracy and small occupied space. The mechanism comprises a lens group, a peripheral frame, a fixing seat and a lamp housing, wherein the upper end of the peripheral frame is movably connected to the lamp housing through a horizontal rotating shaft mechanism while the lower end is connected with a vertical carrier rod through a ball head connector; the vertical carrier rod is driven by a vertical motor fixed on the lamp housing; the fixing seat is rotationally connected in the peripheral frame along a vertical direction; one side of the fixing seat is fixedly connected with the lens group while the other side is movably connected with a horizontal carrier rod; and the horizontal carrier rod is driven by a horizontal motor fixed on the peripheral frame. Under the pushing action of the horizontal carrier rod driven by the horizontal motor, the fixing seat can drive the lens group to rotate horizontally so as to fulfill the aim of controlling the lamplight to rotate horizontally as required; and the peripheral frame can rotate around the horizontal rotating shaft mechanism at the upper end of the peripheral frame under the pushing and pulling forces of the vertical carrier rod to drive the lens group to oscillate up and down so as to fulfill the aim of controlling the lamplight to rotate vertically.

Description

technical field [0001] The invention relates to an automobile lighting system, in particular to an adaptive headlamp executive mechanism. Background technique [0002] The traditional headlight system has dark areas in the lighting of curves, highways, rural areas, and adverse weather, which seriously affects the driving safety of the car. Therefore, it is necessary to develop a headlight that adjusts the lighting direction by adapting to various road conditions and dark environments. to eliminate safety hazards. Currently there are automatic level adjustment technology (ALS, auto leveling system) and adaptive headlight technology (AFS, adaptive-front lighting system). For example, the publication number is CN1318484, a headlight and its driving mechanism disclosed on 2001.10.24, adopting the motor under the bracket platform to drive the reflector to drive the bracket to rotate, and the reflector passes through the spring The ball forms elastic contact with the bracket, an...
