Description

Automotive night meeting and overtaking light controller

The utility model relates to a kind of car bulb automatic control device.

Cars meeting at night, the chaufeur of overtaking other vehicles will remove operating switch with hand or pin, conversion light.There is the people that the meeting beam automatic guidance has been proposed some schemes in recent years, as CN2074261U cars meeting at night light auto mat, adopt existing NE555 integrated package to form country beam and passing light control circuit, the executive circuit that starting is formed with field effect transistor, also design a multi-vibrator at last and control the unlatching of country beam, passing light, in fact, turn off country beam during meeting, open passing light and only solved the dazzling problem of light when closing on, can't solve the problem that chaufeur is seen road ahead clearly.In order to address this problem, the automatic meeting device of CN2083125U power actuated vehicle, it has increased a left back illuminator that inclines in the automobile left side, and this lamp is bright during meeting, provides light source according to the road for the other side's vehicle, has solved the phenomenon that chaufeur when two cars are met does not see the road at the moment.Automobile is when overtaking other vehicles, and with the operation that has frequent cut-out, turn-on lamp switch, and two above-mentioned utility models all do not relate to the control of meeting beam yet.

The purpose of this utility model provides a kind of cars meeting at night, the lamp dimmer of overtaking other vehicles, and level does not adopt relay control mode.When the other side's light shines, country beam SELF CL several seconds, passing light and the left back lamp that inclines are bright, and meeting is lighted country beam later again.When overtaking other vehicles, country beam will glimmer automatically.

Referring to accompanying drawing the utility model electrical schematic diagram, can understand it is to realize like this.

A kind of cars meeting at night, the lamp dimmer of overtaking other vehicles is characterized in that comprising the optical receiving set of being made up of D2, D3, R3, R4, C3, BG1; The circuit for reversing of forming by R5, R6, C4, C5, C6, IC2; The delay driving circuit of forming by D5, R9, R11, R12, C7, C8, IC3, BG4; The phase inverter of forming by R6, R8, BG3; The oscillating circuit of forming by D1, R1, R2, C1, C2, IC1; The executive circuit of forming by D4, D7, R7, BG2, J1, wherein of the input end IC2 of the emitter of the mouth BG1 of optical receiving set and circuit for reversing 2., 6. pin links to each other, the mouth IC2 of circuit for reversing 9. pin link to each other with the base stage of the input end BG2 of executive circuit through R7, D4, relay J 1 is serially connected between the collector and power supply of BG2, and normally closed contact J1-2 connects country beam ZD1, normal opened contact J1-1 and connects passing light ZD2 and the left back lamp ZD3 that inclines; The control end of IC2 the 5. pin and output end of oscillating circuit IC1 the 4. pin link to each other, oscillating circuit control end IC1 the 3. pin links to each other with K switch 1 through D1, the other end of K1 connects power supply; IC2 5. pin also connect the input resistance R8 of phase inverter, the collector of inverter output BG3 and meet D5, R9 after 2., 6. pin links to each other with delay driving circuit input end IC3, IC3 mouth 3. pin is connected to the base stage of BG4 through R11, the collector of BG4 is connected to the BG2 base stage of executive circuit, the adhesive of control relay J1 through R10, D6.

Time delay circuit that delay start-up circuit of the present utility model is made up of D5, C7, C8, D9, IC3 and the driving circuit of being made up of R11, R12, BG4 constitute.

Oscillating circuit in the accompanying drawing, base application circuit during base integrated package representative type when time delay circuit is NE555.Circuit for reversing is the Chang Lu commonly used that the NE555 integrated package is formed.

The utility model is finished meeting, the automatic guidance light transition process of overtaking other vehicles is as follows:

Transistor BG1 conducting when the car bulb that head-on comes shines electro-optical tubes D3,2., 6. the IC2 input end obtains voltage, IC2 the 9. pin output direct current with voltage, make the BG2 conducting by R7, D4, relay J 1 adhesive, contact J1-2 disconnects on the one hand, and country beam goes out, contact J1-1 connects on the other hand, and passing light, the left back lamp that inclines are bright.After 2～3 seconds, the reverse circuit upset, 9. pin no-voltage output of IC2, the BG2 base stage is ended because of no-voltage, and relay discharges, and contact J1-2 connects, and country beam lights again.IC2 is the pin output voltage 5., charge to C7 through R8, BG3, R9, after C7 voltage reaches certain value, make 3. pin no-voltage output of IC3, BG4 ends, voltage is added to the BG2 base stage by R10, R6, make the BG2 conducting, the relay adhesive, J1-1 connects passing light, the left back lamp that inclines is bright, J1-2 disconnect country beam go out promptly realize country beam by bright to go out, by going out to bright, and then the flicker secondary that goes out.After two car meetings, during unglazed irradiation D3, BG2 ends, and relay J 1 discharges, and this moment, J1-2 connected, and becomes country beam according to the road.

In the time will overtaking other vehicles, the chaufeur K that only need close a switch, oscillating circuit work, IC1 4. pin exports an intermittant voltage and adds to 5. pin of IC2, and at this moment, IC2 9. pin exports a backlash circuit and adds to transistor BG2 base stage through R7, D4, makes BG2 moment switching; Also switch-on and-off of relay J 1, with relay tip, the country beam that J1-2 links to each other will glimmer, and send the signal of overtaking other vehicles.After overtaking other vehicles, cut-off switch K gets final product.

The utility model is simple, and circuit need not debugged.As long as the errorless work that gets final product is installed, extensively with hand automobile night travel, meeting or the use of overtaking other vehicles.
