Double-module synchronous horizontal adjustment system for vehicle lamp

Abstract

The invention provides a double-module synchronous horizontal adjustment system for a vehicle lamp. The system comprises a low beam support, a high beam support, an adjusting unit and a linkage rod mounting area, the adjusting unit comprises an adjusting gear, an adjusting screw, a limiting support, an adjusting sliding block and a clamping spring, and the adjusting unit is assembled and connectedwith at least one of the low beam support and the high beam support, wherein the linkage rod mounting area comprises a linkage rod, a first metal sheet and a second metal sheet; a high beam module and a low beam module are respectively installed or integrated on the low beam support and the high beam support; and the low beam support and the high beam support which are installed on the two sidesof the linkage rod are assembled on the shell in a limited mode through the first metal sheet and the second metal sheet. The adjusting gear is rotated to push the adjusting screw to move front and back in the vehicle body direction, the lever effect of the linkage rod is used for driving the low beam support and the high beam support to rotate relative to respective fixing shafts, and the low beam module and the high beam module integrally and synchronously move front and back in the vehicle body direction, namely horizontal adjustment in the same direction is achieved.

Description

technical field [0001] The invention relates to the technical field of automobile lamps, in particular to a dual-module synchronous level adjustment system for automobile lamps. Background technique [0002] The continuous development of technology in the field of automotive lights has made the structure of the car lights more and more complicated. Most of the far and low beams no longer use a single dual-function module, but use dual modules to achieve it. Horizontal dimming has increasingly become a must-have function for car lights. [0003] The realization of the far and low beam level dimming of car lights requires a corresponding adjustment system in terms of structure. In the existing level adjustment system, there are usually only two forms. One form is only a group of level adjustment systems to realize single The level adjustment of the low beam, this design can no longer meet the requirements of most automobile OEMs and customers; another form is to design a set ...

[0003] The realization of the far and low beam level dimming of car lights requires a corresponding adjustment system in terms of structure. In the existing level adjustment system, there are usually only two forms. One form is only a group of level adjustment systems to realize single The level adjustment of the low beam, this design can no longer meet the requirements of most automobile OEMs and customers; another form is to design a set of two level adjustment systems for each of the dual modules to achieve the individual level of the dual modules. Adjustment, this design not only needs to occupy a large internal space of the lamp body, but also cannot avoid the adjustment of the two sets of horizontal adjustment systems due to assembly tolerances, which will cause the light shape of the low beam and high beam to not match. Multiple design changes, production line installation adjustments, etc.
