The invention relates to a dimming method and device for an automobile headlamp. The dimming device comprises a lower supporting plate and a fixed block, a sliding rod is installed above the lower supporting plate, a sliding block is arranged above the sliding rod, the fixed block is arranged on one side of the sliding block, a rotating shaft is connected to one side of the fixed block, a movable rod is connected to the upper portion of the rotating shaft, a rotating shaft is installed in the middle of the movable rod, and one side of the lower supporting plate is connected with a lead screw. The dimming method and device for the automobile headlamp have the beneficial effects that by installing the movable spring on the inner side of the connecting rod, when the whole device is impacted, a protection effect can be achieved through the front installing plate, meanwhile, when the protection plate is impacted, the ejector rod on one side of the protection plate abuts against the movable spring on one side, and the movable spring rebounds under the jacking of the jacking rod, so that the effect of damping and protecting the whole device is effectively achieved, meanwhile, the whole device can better play a role in protecting an internal lamp shell, and operation of a user is facilitated.

    本发明涉及一种汽车前大灯的调光方法及装置,包括下支撑板和固定块,所述下支撑板的上方安装有滑杆,且滑杆的上方设置有滑块,所述固定块设置于滑块的一侧,且固定块的一侧连接有转轴,所述转轴的上方连接有活动杆,且活动杆的中间位置安装有转动轴,所述下支撑板的一侧连接有丝杆。本发明的有益效果是:该汽车前大灯的调光方法及装置通过安装连接杆内侧的活动弹簧,当整个装置受到撞击的时候,可以通过前安装板起到保护的作用,同时防护板受到撞击会通过防护板一侧的顶杆顶住一侧的活动弹簧,在顶杆的顶压下活动弹簧会回弹,有效地起到减震保护整个装置的作用,同时也使得整个装置可以更好的起到保护内部灯壳的作用,方便使用者进行操作。
