Specific embodiment

Below in conjunction with the accompanying drawings further is made to the utility model automobile dimming-distance light automatic device for changing light with specific embodiment Description：

Fig. 1 is the connection schematic diagram of the utility model automobile dimming-distance light automatic device for changing light, and Fig. 2 is part 1 in Fig. 1 Component composition figure.In figure, the automobile dimming-distance light automatic device for changing light, including automobile dimming-distance light manual change device 10, vehicle mounted electric Source 12 and Bidirectional manual switch 6, include high beam contact 7 and dipped headlights contact 5 on Bidirectional manual switch 6, vehicle power 12 with Two-way Self-retaining electromagnet 11 is provided between Bidirectional manual switch 6, two-way Self-retaining electromagnet 11 includes left and right two magnet Slide bar 3 between 2 and 4 and two magnet, two-way Self-retaining electromagnet 11 is also associated with control module 1 and reverse electrical source 13, institute Control module 1 is stated including photo resistance 14, analog-digital converter 15 and single-chip microcomputer 16.Photo resistance 14, modulus in control module 1 Converter 15 and single-chip microcomputer 16 are serially connected, and the one end of control module 1 connects the positive pole of reverse electrical source 13, the other end and two-way self-insurance The left magnet 2 held in electromagnet 11 connects, and the negative pole of reverse electrical source 13 is connected on slide bar 3.The positive pole of vehicle power 12 with it is double Connect to the slide bar 3 in Self-retaining electromagnet 11, the connection Bidirectional manual of right magnet 4 switch 6 in two-way Self-retaining electromagnet 11, The connection dipped headlights of left magnet 2 contact 5.

Photo resistance is used for into this automobile dimming-distance light automatic device for changing light, when night drives a vehicle, if opposite is without car, control module 1 place circuit is in due to the not up to advance threshold value arranged in single-chip microcomputer 16 of intensity of illumination, then the place circuit of control module 1 Off-state, at this moment, slide bar 3 is connected with right magnet 4, and automobile dimming-distance light manual change device 10 is in manual mode, Si Jike It is operated manually (distance-light)；When there is car on opposite, vehicle is constantly close, and opposite car light also can be continually changing by force, The data signal that single-chip microcomputer 16 constantly transmits analog-digital converter 15 is compared with the threshold value of setting in single-chip microcomputer 16, once reach To or more than set threshold value, the place circuit ON of control module 1 is acted on, slide bar 3 by the reversing the current of reverse electrical source 13 It is connected with left magnet 2, and disconnects with right magnet 4, Bidirectional manual switch 6 is with high beam contact 7 in failure contact condition, distance light Lamp driver 9 does not work, while left magnet 2 is connected by dipped headlights contact 5 with dipped beam lamp driver 8, dipped headlights is opened, high beam Extinguish.After vehicle is crossed, the resistance of photo resistance 14 recovers initial value, and the place circuit of control module 1 disconnects, slide bar 3 again with Right magnet 4 connects, and connects Bidirectional manual switch 6, and this device recovers distance-light MANUAL CONTROL mode again.

This device can automatically control distance-light conversion, can avoid the high beam of driving at night automobile so that the driver on opposite produces The phenomenon of the driving accident that life is dazzling and causes, effectively reduces the generation of driving at night accident, ensure that night drives significantly Security.

The above, is only preferred embodiment of the present utility model, not makees any formal to the utility model Restriction, although the utility model is disclosed above with preferred embodiment, but is not limited to the utility model, any ripe Know professional and technical personnel, in the range of without departing from technical solutions of the utility model, when the method using the disclosure above and Technology contents are made a little change or are modified to the Equivalent embodiments of equivalent variations, as long as being without departing from the utility model technology The content of scheme, above example is made any simple modification according to technical spirit of the present utility model, equivalent variations with Modification, still falls within the range of technical solutions of the utility model.
