The rotation of the motor drives the metallic threaded drive rod to move forwards and backwards in a straight line. A sliding block is arranged at the end part of the metallic threaded drive rod, the sliding block is connected with an optical unit (6), the rectilinear motion of the sliding block is converted into the rotary motion of the optical unit, so that the optical unit can rotate within the certain angle, thereby regulating the light direction of the car headlight.
Description
Technical field
The present invention relates to Vehicular lamp device, particularly, the present invention relates to a kind of rotary executive device that is used for automobile front shining lamp adjustment system.The rotary executive device of described automobile front shining lamp adjustment system can be converted into straight-line motion with rotatablely moving, and straight-line motion is converted into to rotatablely move again, thereby realization is to the adjustment of car headlamp direction of illumination.
Background technology
Night driving is only loaded onto good head lamp and is adjusted the angle of inclination of head lamp whenever and wherever possible, just can hold car successfully, guarantees traffic safety.
Yet, when driving a vehicle night, to meet, occasions such as road condition change, vehicle condition variation, brake and speed-raising at two cars, the head lamp of conventional truck Lighting System often is difficult to the illumination that provides timely, enough, to protect traffic safety.
At first, situations such as the variation of load carrying ability, brake and speed-raising can cause that all the angle of inclination of vehicle body changes, and then the light beam inclination angle of passing light is changed.Fill up the back in-support carriage of luggage and suddenly speed-raising all can cause the tailstock to sink, headstock is raised, so that light shakes to such an extent that the opposite chaufeur of sending a car can't keep one's eyes open.During brake, headstock can descend to prick again.Especially when emergency braking,, may cause the sighting distance forfeiture because of pricking severely under the headstock.
In addition, the conventional truck Lighting System is because its illumination direction is total parallel with the vehicle body direction, and therefore when Vehicular turn, possibility is owing to Lighting System can not provide enough illuminations to cause causing danger for the actual travel direction of vehicle.
For this reason, people expect a kind of headlamp lighting variotrol of novel concept, described headlamp lighting variotrol can be according to the sudden change of different variation road conditions, vehicle condition and the light beam inclination angle, illumination direction and even the sighting distance that cause thereupon, and the sudden change of angle of inclination, illumination direction and even the sighting distance of car headlamp is in time regulated.Thus, guaranteeing when driving a vehicle night, meet, can both in time provide enough illuminations under the situations such as road condition change, vehicle condition variation, brake and speed-raising, to protect traffic safety at two cars.
Chinese patent " 88202665.8 " relates to a kind of automobile lamp automatic control device, it comprises: the photoelectric switching circuit that external optical signals is transformed into electric signal, regulate the light adjusting circuit of car light luminance brightness according to described electric signal, signal generator of cars meeting, overtake other vehicles signal generator and steering controller.This device when two cars near the time, can dim car light gradually, and control king light, secondary lamp replace the glittering meeting signal that sends; It is glittering to control king light when overtaking other vehicles, and sends the signal of overtaking other vehicles; When motor turning, can close king light, play bright secondary lamp simultaneously, so that other people see the trend of automobile clearly.Yet this device is difficult in time adjust the angle of inclination of head lamp.Can not keep in full accord with driver's visual angle owing to gather the circuit position of optical signal simultaneously, can bring the deviation of vision to the driver.What is more, and this circuit can be judged other illumination light of vehicle-surroundings the light of conclusion of the business meeting vehicles by accident and cause the Lighting System misoperation, thereby causes danger.In addition, this apparatus structure complexity is used inconvenience.
Summary of the invention
For overcoming the problems referred to above, the invention provides a kind of rotary executive device of automobile front shining lamp adjustment system.The rotary executive device of described automobile front shining lamp adjustment system is provided with a slide block by the end at metal threaded drive link, slide block links to each other with optical unit by driving lever, change the straight-line motion of slide block into optical unit rotatablely move, thereby realize the rotation of optical unit in certain angle.Described device is fairly simple in assembling and motion, space structure is little, and material cost can reduce greatly, can in time adjust the angle of inclination of head lamp.
The technical scheme of car headlamp rotary executive device of the present invention is as follows.
A kind of rotary executive device of automobile front shining lamp adjustment system has: electrical motor, and crust of the device, the metal threaded drive link that driven by the electrical motor rotation is characterized in that described rotary executive device also comprises:
With metal threaded drive link bonded assembly slide block,
Two ends respectively with slide block and optical unit bonded assembly driving lever,
Guide rail is set in the crust of the device, described slide block can along this guide rail with housing that electrical motor links to each other in do reciprocal line sliding and move,
Be formed with shrinkage pool in the slide block, slide block is connected by shrinkage pool and driving lever,
Described optical unit axle props up in outer cover of lamp holder,
The head spheroid of driving lever embeds in the shrinkage pool, thus, makes bulb in the tangential motion of maintenance and slide block, can certain relative motion be arranged along guide rail normal direction and slide block again,
That is, bulb is in the drive moving linearly with slide block, and driving lever also drives the optical unit motion thereupon, because the optical unit axle props up on outer cover of lamp holder, promptly form around the rotary oscillation of axle fulcrum, thereby, realize making the straight-line motion of slide block be converted into rotatablely moving of optical unit.
