Abstract
The utility model discloses an intelligent automatic dimming device for the head lamp of an automobile which comprises a signal radiation receiving circuit A, a single chip computer control circuit B and an execution circuit. The device is connected with a near-light lamp, a far-light lamp and a direction indicator lamp of the automobile, and is controlled by a dimming switch and a direction indicator lamp switch of the automobile. When two automobiles provided with the device meet each other at night, the one which turns on the near-light lamp can transmit a signal to the other one (the automobile turns on the far-light lamp), and the receiver of the other one accepts the signal in an effective distance. At the same time, the far-light of the other one gradually turns off automatically and the near-light gradually turns on automatically. After the meeting, the far-light recovers by the self. The entire dimming process has natural visual and no abrupt change. Besides, when an automobile turns and turns on the direction indicator lamp, the one can not be forced to dim in order to ensure driving safety. If the automobiles are assembled with the dimming device uniformly, the existing dimming when the automobiles meet can be improved fundamentally, the accidents caused by the glaring far-light lamp at night can be greatly reduced, and the utility model is favorable to the traffic safety.
Description
Technical field
The utility model relates to the automotive lamp light control device, and refering in particular to is intelligent automatic device for changing light of front headlight of motor vehicle.
Background technology
Front headlight of motor vehicle possesses distance light, two kinds of illumination functions of dipped beam.Self-propelled vehicle is at night during cruising, the general country beam that adopts throws light on, and when two car intersections, dazzle the eyes for preventing country beam, avoid consequent safety traffic accident, national communication portion is about the self-propelled vehicle security regulations: during motor-driven vehicle meeting at night, outside 150M, the meeting both sides just should consciously become the passing light illumination with head lamp, because self-propelled vehicle is far away, the conversion of dipped beam is manually to be handled by chaufeur, because of the chaufeur carelessness, quality is low, reasons such as malice unlatching, current mobility car night safe meeting is unsatisfactory, dazzle the eyes the traffic accident that causes because of country beam night and happen occasionally, be unfavorable for safe driving.
Summary of the invention
The automatic device for changing light of front headlight of motor vehicle that provides a kind of automatic guidance intersection vehicle distance light dimming rational in infrastructure, esy to use, safe and reliable but the purpose of the present utility model device is to overcome the deficiency of existing meeting rule.
The utility model is to adopt following proposal to realize: it is made up of signal transceiver circuit A, single chip machine controlling circuit B, executive circuit, transceiver module one termination power negative pole, and the other end is IC in single chip machine controlling circuit
1Link to each other with positive source, its A, B bipod respectively with IC

6Form, executive circuit is made up of relay J and normally closed contact J-1 thereof and open contact J-2.
The utility model can force intersection at night vehicle to adopt passing light illumination, the safety that can effectively improve night travel owing to adopt said structure.Its principle of work is summarized as follows:
When K connects 1 contact, D
1Bright, P
1-3Be in high level, judge P by micro controller system
1-3Be high level, make transceiver module be in emission state, emission stops after some seconds.
When K connects 2 contacts, D
2Bright, P
1-2Be in high level, judge P by micro controller system
1-2Still be high level, after some seconds, the indication transceiver module is in receiving condition.
When receiving native system signal, then P
1-4Be in high level, relay J action, J
1-1 disconnects J
1-2 closures.Micro controller system starts the asymptotic change light path preface of time-delay, P simultaneously
1-0The series of pulses that the pin output pulse width reduces successively is by VT
1The conversion of photoelectric coupling circuit is through T

3Convert D to
1On the linear process of voltage from 0V to 12V.Thereby in some seconds, make dipped beam D
1Finish by dark to bright linear progression process.And P
1-1Pin and P
1-0Pin is put anti-and synchronous working, P
1-1The series of pulses that the pin output pulse width increases successively is by VT
2The conversion of photoelectric coupling circuit is through T
4.T
5.T
6Convert D to
2On the linear process of voltage from 12V to 0V, make distance light D
2Finish bright to dark linear asymptotic process.When distance light becomes dipped beam (this moment can launch), after some seconds, under the micro controller system indication, P
1-0The series of pulses that the pin output pulse width increases successively makes VT
1The conversion of photoelectric coupling circuit is by T
1.T
2.T
3Convert D to
2On the linear process of voltage from 12V to 0V, dipped beam D
1By bright deepening.While P
1-1Pin is put anti-and synchronous working, D
1-1The series of pulses that the pin output pulse width reduces successively, thus make distance light D
2Progressive by secretly brightening.As dipped beam D
1Become distance light D fully
2The time, relay J resets, J
1-2 disconnect J
1-1 is compound.At this moment, because P
1-2Be high level, transceiver module is in receiving condition again.
If K
0When connecting 3 contacts, IC
2P
1-5Pin is a high level, passes through IC
2Program indication, transceiver module will be in dormant state (neither emission, also wave-off).K
0Disconnect 3 contacts after some seconds, transceiver module will restart work.
This shows that this device work is by self-propelled vehicle self beam deflector switch K and turn signal swich K
0Control.When self-propelled vehicle is opened passing light (K connects 1 contact), transceiver module (the place ahead) is towards periphery launched modulated signal.When self-propelled vehicle is opened country beam (K connects 2 contacts after some seconds, after 1 second), transceiver module is in receiving condition.During two motor-driven vehicle meeting at night that this device is housed, when a side opens passing light, this self-propelled vehicle just transmits to the other side's (switch-on distance light self-propelled vehicle), and (as 200M) makes the other side's received signal and finish the change photoreduction process in active distance, thereby can avoid distance light to dazzle the eyes.Because this device adopts single chip machine controlling circuit, its asymptotic change light path preface writes IC by Programmer simultaneously
2, IC during program start
2P
1-0Pin and P
1-1Pin is put anti-and synchronous working, makes distance light gradually deepening the time, and dipped beam also brightens gradually.Whole change photoreduction process vision nature does not have the sudden change sense, helps traffic safety.And when the self-propelled vehicle negotiation of bends, because K
0Connect 3 contacts, transceiver module is in dormant state, can not become light by force in the time of can guaranteeing negotiation of bends, helps traffic safety.
