Abstract
The utility model provides a dimming device of a headlamp of an automobile and belongs to the technical field of automobiles. The dimming device of the headlamp of the automobile resolves the problem that when an illumination direction of the existing headlamp of the automobile deviates from the standard direction, the direction cannot be corrected, thereby causing the bad illumination effect. The dimming device comprises a controller, a sensor device, and a driving motor, wherein the sensor device and the driving motor are in electric connection with the controller. The sensor device is arranged on an automobile chassis and is used for detecting altitude signals from the automobile chassis to the ground, and the altitude signals can be transmitted into the controller by the sensor device. The controller can conduct analysis and process according to the altitude signals received by the controller, and then transmits controlling signals to the driving motor for controlling the driving motor to control rotation of the headlamp through a drive structure. The dimming device of the headlamp of the automobile has the advantages that when the illuminating direction of the headlamp deviates from the standard direction, the illumination direction can be adjusted in time, thereby improving illumination effect.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of light modulating device of automobile front.
Background technology
Automobile front is installed on the front two side ends of vehicle body, and the illumination that is used for travelling is used.Existing automobile front exists problem: mainly be in the vehicle traveling process, its automobile front can cause that direction of illumination departs from the situation of reference direction under the impacts such as boot heavy burden, for a long time vibrations and height road conditions, cause the head light illuminating effect not good.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, thereby has proposed a kind of light modulating device that can revise the automobile front of head light direction of illumination raising illuminating effect.
The purpose of this utility model can realize by following technical proposal: a kind of light modulating device of automobile front, it is characterized in that: comprise controller and the sensor device that is electrically connected with controller, CD-ROM drive motor, described sensor device is arranged on the car chassis for detection of car chassis to the altitude signal on ground and can send the altitude signal that detects to controller, controller can carry out analyzing and processing according to the altitude signal of its reception, then sends out control signal to the rotation of CD-ROM drive motor control CD-ROM drive motor by drive mechanism control head light.
In the light modulating device of above-mentioned a kind of automobile front, described sensor device comprises four position transdusers and is installed in respectively four tire places of car chassis.
In the light modulating device of above-mentioned a kind of automobile front, described drive mechanism comprises worm-and-wheel gear and push rod, and CD-ROM drive motor is successively by worm-and-wheel gear and the rotation of top rod driving head light.
Compared with prior art, the light modulating device of this automobile front can carry out 360 ° of omnibearing angel adjustment to head light, when the automobile front direction of illumination departs from reference direction, detect car chassis to the altitude signal on ground by sensor device, controller is judged actual vehicle body situation by these altitude signals that detect and is sent corresponding control signal and by CD-ROM drive motor and drive mechanism head light is made corresponding spinning movement, head light is adjusted to when the normal orientation of front body situation, improved the head light illuminating effect.
Description of drawings
Fig. 1 is functional block diagram of the present utility model.
The specific embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, the light modulating device of this automobile front comprises controller and the sensor device that is electrically connected with controller, CD-ROM drive motor, and sensor device comprises four position transdusers and is installed in respectively four tire places of car chassis.Sensor device is arranged on the car chassis for detection of car chassis to the altitude signal on ground and can send the altitude signal that detects to controller, controller can carry out analyzing and processing according to the altitude signal of its reception, then sends out control signal to the rotation of CD-ROM drive motor control CD-ROM drive motor by drive mechanism control head light.
Drive mechanism comprises worm-and-wheel gear and push rod, and CD-ROM drive motor is successively by worm-and-wheel gear and the rotation of top rod driving head light.
Automobile front bears a heavy burden at boot, the impacts such as long-time vibrations and height road conditions are lower, can cause that direction of illumination departs from reference direction, detect respectively the chassis at four tire places of automobile to the altitude signal on ground by four position transdusers, these altitude signals that then will detect send controller to, controller carries out analyzing and processing by the altitude signal that these are detected and judges actual vehicle body situation and send corresponding control signal control CD-ROM drive motor and by drive mechanism head light is made corresponding spinning movement, head light is adjusted to when the normal orientation of front body situation, improved the head light illuminating effect.
Controller in the light modulating device of this automobile front adopts a kind of manned vehicle monolithic integrated circuit; this circuit has lower position error, high noise immunity; low-current power supply; temperature protection; open circuit and the short circuit indication; the short circuit motor pins, output over-voltage protection, the advantages such as work that can be reliable and stable under complex environment.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
