Self-adaption control vehicle headlamp structure and control method

Abstract

The invention discloses a self-adaption control vehicle headlamp structure and a control method. First rotating shafts are in fixed connection with the left and right sides of a lampholder; a hexagonal-prism-shaped electromagnet is arranged at the bottom of each hexagonal-prism counter bore; the bottoms of the cylindrical-shaped counter bores of a second rotating shaft and a third rotating shaft are correspondingly in coaxial connection with telescopic rods with cross sections being triangular; the telescopic rods are coaxially in fixed connection with armatures with the outline being a hexagonal-prism; the third rotating shaft is coaxially sleeved with a second gear meshing with a first gear; a fourth rotating shaft is coaxially sleeved with the first gear; a pendulum bob is arranged under the first gear; the right end of the right first rotating shaft is coaxially fixedly sleeved with a first bevel gear; the first bevel gear meshes with a second bevel gear which is horizontal to a center shaft in a front-and-rear mode; the first bevel gear is in fixed connection with an output shaft of a stepping motor; the second rotating shaft and the third rotating shaft are sleeved with bearings; and the second rotating shaft is in fixed connection with a lamp frame. Different driving conditions of a vehicle can be matched, and different responses are achieved according to different roadconditions.

Description

technical field [0001] The invention relates to the electronic control technology of automobile headlights, in particular to a structure and method capable of self-adaptively controlling the irradiation direction of automobile headlights, so that the headlights can fully illuminate the driving direction of the automobile. Background technique [0002] The traditional car headlights have a fixed irradiation direction relative to the body. When the car is driving on an uneven road or uphill or downhill, the headlights cannot fully illuminate the driving direction of the car, which leads to Traffic accidents caused by insufficient lighting at night. According to incomplete statistics, at night, the probability of vehicle accidents when the lighting is insufficient is three times that when the lighting is sufficient. Aiming at this problem, a kind of car light steering system and its car light rotary actuator have been announced in the Chinese patent application number 20111038...

Problems solved by technology

Aiming at this problem, a kind of car light steering system and its car light rotary actuator have been announced in the Chinese patent application number 201110385418.5. The rotation of the lamp, the device has a simple structure, reliable transmission, and can reduce the cumulative error in the rotation by comparing the received signal value with the initialized signal value, but the device only has the active process of motor control, for The headlights do not need to be rotated when the road surface is uneven, and the headlights need to be rotated in real time when the car is driving on a bumpy road. The device cannot respond differently to different road conditions, and the motor Long-term intervention will not only damage the service life of the motor, but the long-term swing of the light will also cause visual fatigue to the driver, which is not conducive to safe driving

Another example is the Chinese patent application number 201610396122.6, which discloses a car headlight that adapts to loading conditions and road conditions. The light has a certain angle compensation value; the device is simple in structure, low in cost, and has no loss of light; but the problem with this device is that when the car is going up and down, it cannot be more accurately changed through the active process of motor intervention.
