Description
Technical Field
The utility model particularly relates to an automatic dimmer of motor vehicle.
Background
With the increasing number of motor vehicles, the bad habits of the operation of drivers are increased, the technical level is not enough, the traffic police law enforcement difficulty is high, a large number of people do not change a high beam into a low beam when meeting at night, so that a large number of traffic accidents are caused, and great loss is caused to lives and properties of people.
Disclosure of Invention
To the weak point among the prior art, the utility model provides an automatic light changer of motor vehicle. The utility model has the characteristics of simple to use, the security is high.
In order to achieve the above purpose, the utility model discloses technical scheme as follows:
an automatic dimmer for motor vehicles comprises a ranging radar, a camera, a signal processor and a dimming circuit; the camera captures vehicle information on a road ahead and transmits the vehicle information to the signal processor; the vehicle measures distance through a radar; the data after radar ranging is transmitted to a signal processor through a signal line; the signal processor processes the vehicle information, sends a working instruction and transmits the working instruction to the dimming circuit;
the dimming circuit consists of a dipped headlight, a high beam headlight, a relay, a high beam and low beam change-over switch and a headlight switch; the high beam and the dipped headlight are connected in parallel and are respectively connected with one end of the relay; one end of the relay is connected with the signal processor, and the other end of the relay is connected with the high beam and low beam lamp change switch; the other end of the high beam and low beam light changing switch is connected with a headlight switch; the headlight switch is connected with the positive electrode of the power supply; and the negative electrode of the power supply is connected with a grounding iron.
Further, the camera captures whether a vehicle runs in front of the vehicle, and transmits vehicle running information to the signal processor.
Further, after the radar receives the vehicle running information transmitted by the signal processor, ranging between vehicles is completed, and the vehicle running information after ranging is transmitted to the signal processor through a signal line; the signal processor sends instructions to the dimmer circuit.
Has the advantages that: the utility model provides an automatic light changer of motor vehicle, through the car that traveles of making a video recording head present the place ahead, range radar begins work afterwards, makes detection and conveying work order according to the interval of traveling of two cars, can effectively avoid using improper emergence dangerous condition because of light.

Detailed Description
The present invention is described below with reference to specific examples. It will be understood by those skilled in the art that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention in any way.
An automatic dimmer for motor vehicles, as shown in fig. 1, comprises a distance measuring radar (7), a camera (6), a signal processor (5) and a dimming circuit; the camera (6) captures vehicle information on a road ahead and transmits the vehicle information to the signal processor (5); the vehicle carries out distance measurement through a radar (7); the data after the radar (7) is subjected to ranging is transmitted to the signal processor (5) through a signal line; the signal processor (5) processes the vehicle information, sends a working instruction and transmits the working instruction to the dimming circuit; the dimming circuit consists of a dipped headlight (9), a high beam headlight (8), a relay (4), a high beam and low beam change-over switch (3) and a headlight switch (1); the high beam lamp (8) and the dipped headlight (9) are connected in parallel and are respectively connected with one end of the relay (4); one end of the relay (4) is connected with the signal processor (5), and the other end is connected with the high beam and low beam lamp change switch (3); the other end of the high beam and low beam light changing switch (3) is connected with the headlight switch (1); the headlight switch (1) is connected with the positive pole of the power supply; the negative pole of the power supply is connected with a grounding piece (2).
The camera (6) captures whether a vehicle runs ahead of the vehicle, and transmits information of the running of the vehicle to the signal processor (5). After the radar (7) receives the vehicle running information transmitted by the signal processor (5), the distance measurement between vehicles is completed, and the vehicle running information after the distance measurement is transmitted to the signal processor (5) through a signal line; the signal processor (5) sends instructions to the dimmer circuit.
After the dimming circuit receives the working instruction, the high beam of the vehicle is changed into the dipped headlight; the specific implementation is as follows: when the camera (6) finds that a vehicle is in front, the distance measuring radar (7) starts to work, and when the distance between the two vehicles is 150 meters, the signal processor (5) sends a working instruction to the dimming circuit, so that the dimming circuit starts to work; the vehicle is changed from high beam to low beam, when the vehicle is in low beam mode, the dimmer switch cuts off the power supply and stops working; when the distance between the two vehicles is 0 m, namely the meeting is finished, the signal processor (5) releases the instruction of the light changing circuit, the light changing circuit stops working, and the vehicle returns to the previous working state.
