Headlamp dimming support structure

Abstract

The invention provides a headlamp dimming support structure. The headlamp dimming support structure comprises a manual dimming assembly, the manual dimming assembly comprises a manual dimming guide rail, a universal base, a guide rail sleeve, a metal clamping piece and a manual dimming screw, the guide rail sleeve and the manual dimming guide rail are in sliding connection, the guide rail sleeve is connected with the universal base, the guide rail sleeve is in threaded with the manual dimming screw, and the metal clamping piece is connected with the guide rail sleeve and the manual dimming screw. The structure has the beneficial effects that shaking generated by the gap between the manual dimming screw and the guide rail sleeve can be reduced, and the scratching defect is avoided.

Description

technical field [0001] The invention relates to an automobile headlamp, in particular to a headlamp dimming bracket structure. Background technique [0002] Headlights are important regulations and appearance parts. According to the requirements of relevant regulations, the far / low beam needs to be adjustable up, down, left, and right. Common dimming is divided into two methods: motor dimming and manual dimming. Motor dimming mainly controls the up and down swing of the light-emitting component, and manual adjustment is required; manual dimming mainly controls the left-right swing of the light-emitting component. [0003] The existing headlight dimming structure such as figure 1 shown. The far and near light lens assembly 1 is fastened on the bracket 4 by screws, and the motor dimming guide rail 2 and the manual dimming guide rail 5 are also clamped on the bracket 4 through the universal seat 7; when the motor 3 receives an electrical signal, the The dimming nail rotates...

AI Technical Summary

Problems solved by technology

The far and near light lens assembly 1 is fastened on the bracket 4 by screws, and the motor dimming guide rail 2 and the manual dimming guide rail 5 are also clamped on the bracket 4 through the universal seat 7; when the motor 3 receives an electrical signal, the The dimming nail rotates in the motor dimming guide rail 2, thereby driving the motor dimming guide rail 2 to drive the bracket 4 and the far and near light lens assembly 1 to swing up and down for dimming; The manual dimming guide rail 5 is rotated to drive the manual dimming guide rail 5 to drive the bracket 4 and the far and near light lens assembly 1 to swing left and right for dimming; the defects of this structure are mainly: there is a gap between the manual dimming screw 9 and the guide rail sleeve 8; When vibration occurs, there will be such a phenomenon between the manual dimming screw 9 and the guide rail sleeve 8 figure 2 The deformation shown, causes the guide rail sleeve 8 to jump in the lamp housing chute, resulting in chalking defects
