The specific embodiment

Fig. 1 is the said automobile lamplight automatic exchanger of the utility model, form by photosensor 1, electronic control circuit 2, relay switch control circuit 3, photosensor 1 is connected with electronic control circuit 2, and electronic control circuit 2 is connected with relay switch control circuit 3; Flashing light alert circuit 5 in the electronic control circuit 2 and photosensor 1 are connected with photoelectric signal processing circuit 4.

Fig. 2 is an embodiment of the said automobile lamplight automatic exchanger of the utility model; the mouth of photosensor 1 is connected with the input end of electronic control circuit 2; the diode D1 that is connected with the relay J M1 in the relay switch control circuit 3 between the mouth of electronic control circuit 2 and the power supply and shields; often opening with normally closed switch K1 of relay J M1 is connected with country beam YGD with passing light JGD, the switching of control long-and-short distant light.Its principle of work is, when main furnace building light switch K is closed, conducting when photosensitive components and parts DG receives enough strong light, this moment, the base stage of aerotron BG1 was active potential, aerotron BG1 ends, its collecting electrode is high potential, so turn-on transistor BG2, starts the relay J M1 that is connected with aerotron BG2 collecting electrode simultaneously, make the switch of relay J M1 cut off normally closed switch, promptly close country beam, and switch to and be communicated with passing light on the normal open switch, carry out country beam and switch to passing light.

In addition, be connected with the relay J M2 in the flashing light alert circuit 5 between the mouth of photosensor 1 and the power supply, the normal open switch K2 of relay J M2 with by free running multivibrator 5 " the flashing light alert circuit 5 formed is connected; be flashing light alert circuit free running multivibrator 5 " working power, free running multivibrator 5 be provided " be connected with the input end of aerotron BG5 in the relay switch control circuit 3.Its principle of work is, when main furnace building light switch K is closed, conducting when photosensitive components and parts DG receives enough strong light, this moment, relay J M2 started, the K switch 2 of relay J M2 switches to normal open switch by normally closed switch, makes flashing light alert circuit free running multivibrator 5 " obtain working power; Started working by the free running multivibrator that elements such as aerotron BG3 and BG4 constitute this moment, the mouth of aerotron BG4 is done the conversion of high active potential, then also conducting constantly and ending of aerotron BG2, control relay JM1 is the state of change-over switch K1 constantly, carry out country beam and switch, realize the effect of flashing light to passing light.

Fig. 3 is another embodiment of the said automobile lamplight automatic exchanger of the utility model.Different with Fig. 2 is in its flashing light alert circuit 5, to be to substitute relay switch with silicon control, for free running multivibrator provides power supply; Promptly between the mouth and power supply of photosensitive components and parts DG, be connected with aerotron BG5, be connected with resistance R 7 between the collecting electrode of aerotron BG5 and the power supply, also be connected with the resistance R 8 that controllable silicon SCR and its control utmost point are in series simultaneously; The negative pole of controllable silicon SCR and free running multivibrator 5 " power end links to each other.Its principle of work is, conducting when photosensitive components and parts DG receives enough strong light, aerotron BG5 ends, and provides energizing signal by resistance R 7, R8 for controllable silicon SCR, this moment, the controllable silicon SCR conducting made flashing light alert circuit free running multivibrator 5 " the acquisition working power.

Fig. 4 utilizes the embodiment of Warning light as flashing lamp.Be on the basis of Fig. 3, at free running multivibrator 5 " mouth increased an aerotron BG6 and relay J M3 and diode D3.The mouth of free running multivibrator is connected with aerotron BG6, is connected the relay J M3 in the relay switch control circuit between the mouth of aerotron BG6 and the power supply, and the normal open switch K3 of relay J M3 is connected with self-propelled vehicle Warning light JSD.Its principle is, do not close when the place ahead vehicle under the situation of country beam, and this car starts the Warning light flicker, closes country beam with prompting the other side vehicle.Difference and the characteristics of this embodiment and Fig. 1 and Fig. 2 are, light conversion portion and light flash part are kept apart fully, and two cover circuit can not produce and influence each other.According to above-mentioned same principle, also often opening with normally closed switch K3 of relay J M3 can be connected with country beam YGD with passing light JGD, with the switching of control long-and-short distant light.

Fig. 5 is for only there being the embodiment that closes country beam and open passing light.Its formation is exactly with the form after the cancellation of the dotted portion among Fig. 2, Fig. 3 and Fig. 4.Dotted portion among Fig. 2, Fig. 3 and Fig. 4 is a flashing light alert circuit 5, comprises flashing light alert circuit switch 5 ', is the source switch part and the flashing light alert circuit free running multivibrator 5 of free running multivibrator ".

Fig. 6 is for only having the alternately embodiment of flicker of country beam and passing light.Its formation is to have cancelled aerotron BG1 and the interlock circuit among Fig. 3.The foregoing relevant portion of this circuit theory is similar, and only for not closing under the situation of country beam when the place ahead vehicle, country beam of this car and passing light be alternately flicker ceaselessly, closes country beam with prompting the other side vehicle.If with aerotron BG1, BG2 among Fig. 4 and interlock circuit cancellation, then can be formed in front vehicles and not close under the situation of country beam, this car starts the Warning light flicker automatically, closes country beam with prompting the other side vehicle.

The said automobile lamplight automatic exchanger of the utility model, its photoelectric signal processing circuit and flashing light alert circuit can be used simultaneously, also can distinguish separately and use.Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6 are exactly several different embodiment that provides.
