What is the significance of the car headlight level adjustment function?

The height of the horizontal illumination of the light can be adjusted.

The height of the headlights is generally adjustable behind the headlights of the car, but more and more models have manual adjustment knobs inside, which can adjust the illumination height of the headlights at will, and even the headlights of some high-end luxury cars can be automatically adjusted by sensors. Make headlight height adjustment.

This function actually plays a role in driving safety. When there are people sitting in the front row or heavy items are placed in the luggage compartment, the car will be in a non-horizontal position due to the change of the suspension stroke.

Precautions for the use of car lights:

When a motor vehicle passes through an intersection controlled by traffic lights, when turning left, turn on the turn signal, and turn on the low beam when driving at night.

When the street lights are turned on at night, or when driving in low visibility conditions such as fog, rain, snow, sand, hail, etc., the headlights, position lights and rear position lights should be turned on.

Do not use high beams when the vehicle behind and the vehicle in front driving in the same direction are driving at close range.

When turning, changing lanes, overtaking, making a U-turn, or pulling over, turn on the turn signal at least 50 meters in advance.

When a motor vehicle passes through sharp bends, slopes, arch bridges, pedestrian crossings or intersections without traffic signal control at night, the high and low beams shall be used alternately to indicate.

What is the principle structure of the height adjustment of the headlights? Like this pencil sharpener, hello is mainly through the input signal of the height position sensor, which is converted into a voltage signal through an algorithm, and the headlight control module drives the motor to control the adjustment of the headlight. Working process: The adjustment switch is installed on the dashboard of the car. Generally, there are 5 gears: 0, 1, 2, 3 and the default gear (the other is the stepless adjustment type). The actuator is installed on the headlight adjuster. In the headlight of the car (or outside the headlight), the headlight adjustment screw tops to the outside of the headlight luminous surface. When the switch is adjusted, the section screw of the headlight adjuster performs telescopic movement, which drives the headlight reflective surface to move and adjust. , so as to adjust the focal length of the reflected light to achieve the effect of adjusting the headlights.
