[0003] However, the step-by-step dimming device in the prior art is generally an integral assembly structure of a stepping motor and a ball plunger, and the movement stroke of the ball plunger cannot be adjusted. , it is necessary to design dimming devices with different strokes. Moreover, since there are various installation structures for step-by-step dimming devices for automobile headlights on the market, it is necessary to design dimming devices for each installation method. The versatility is low, and if the dimming device fails, the entire dimming device needs to be replaced during maintenance, and the cost is high

The invention provides a stepping light dimmer for automobile headlamps. The stepping light dimmer comprises a stepping motor with a threaded output shaft, a base and a ball head ejector rod, wherein the head part of the ball head ejector rod is a ball head, an internally threaded hole matched with the output shaft of the motor is formed in the tail part of the ball head ejector rod, the ball head ejector rod penetrates through a guide hole formed in the center of the base and is connected with the stepping motor, a travel groove is formed on the inner wall of the guide hole, and a positioning block capable of sliding in the travel groove is arranged at the outer side of the tail part of the ball head ejector rod. The light dimmer is flexibly adjustable in travel, high in universality and low in maintenance cost.
Description
technical field [0001] The invention relates to the field of auto parts, in particular to a step-by-step dimming device for an automobile headlight. Background technique [0002] With the development of automotive safety lighting technology, the application of intelligent dimming systems in automobiles is becoming more and more extensive, especially for step-by-step dimming devices used in automotive headlights. This step-by-step dimming device uses stepping motors The way of driving the ball ejector converts the rotary motion of the stepping motor into the linear motion of the ball ejector, so that the linear motion of the ball ejector can be controlled by controlling the stepping motor, thereby adjusting the illumination angle of the automobile headlight. [0003] However, the step-by-step dimming device in the prior art is generally an integral assembly structure of a stepping motor and a ball plunger, and the movement stroke of the ball plunger cannot be adjusted. , it ...
