Accompanying drawing explanation
Fig. 1 is schematic circuit diagram of the present invention.
Detailed description of the invention
Shown in Fig. 1, be the automatic wiper device of a kind of wiper of the present invention, comprise:
Windscreen wiper control unit 7, its first signal input part is connected with the rain sensor 3 be arranged on windshield, secondary signal input end is connected with the windscreen wiper extreme lower position switch 8 be arranged on rain shaving electrical machine 5, and the 3rd signal input part is connected with the car speed sensor 6 be arranged on Automotive transmission output shaft; First signal output part of described windscreen wiper control unit 7 is connected with the ground level of aerotron A, and its secondary signal mouth is connected with the ground level of aerotron B;
Normally opened relay 4, its coil one end is connected with storage battery 1, and the other end is connected with the control end of windscreen wiper control unit 7;
Aerotron A, its collecting electrode is connected with storage battery 1 by the open contact switch of described normally opened relay 4, and its emitter is connected with the collecting electrode of described aerotron B; The emitter of described aerotron B is connected with reference to ground terminal;
Rain shaving electrical machine 5, its input end is connected with the collecting electrode of aerotron A, and the collecting electrode of its mouth aerotron B connects; And storage battery 1, its first mouth is connected with described windscreen wiper control unit 7 by ignition lock 2, and its second mouth is connected with described normally opened relay 4; Wherein, described windscreen wiper control unit 7 controls according to the rainfall signal of the described rain sensor 3 received, the windscreen wiper position signal of windscreen wiper extreme lower position switch 8 and the vehicle speed signal of car speed sensor 6 rotating speed whether described rain shaving electrical machine 5 work and work.
Principle of work is as follows:
1, the rainy day travels
When running car, car speed sensor 6 detects vehicle speed signal, and rain sensor 3 detects " rainy " signal (namely " Vs " signal of rain sensor is a certain value), and windscreen wiper control unit 7 controls the coil adhesive work of normally opened relay 4.Meanwhile, windscreen wiper control unit 7 controls aerotron A not conducting, controls aerotron B conducting; Then rain shaving electrical machine 5 is made to obtain electric, and rotation work.And the rotating speed of rain shaving electrical machine 5 is controlled by the conduction amount of windscreen wiper control unit 7 by Duty ratio control aerotron B; When " rainfall " is larger, the signal value of rain sensor 3 is larger, and dutycycle is larger, and the rotating speed of rain shaving electrical machine 5 is faster, and windscreen wiper action is also faster.
When automobile is as red light stagnation of movement, car speed sensor 6 detects that the speed of a motor vehicle is 0, and it is at low speed that windscreen wiper control unit 7 will control rain shaving electrical machine 5, with economize energy.
2, water spray washing
Now only need open ignition lock 2, need not fire an engine, when rain sensor detects " rainy " signal, it is at low speed that windscreen wiper control unit 7 will control rain shaving electrical machine 5.
3, quit work
(1) when rainy day or water spray washing, as rain shaving blade need be made to quit work, only ignition lock 2 need be closed.When ignition lock 2 is closed, as rain shaving blade is in extreme lower position (namely windscreen wiper extreme lower position switch 8 closes), windscreen wiper control unit 7 controls aerotron B not conducting, controls aerotron A conducting, rain shaving electrical machine 5 produces reverse self-control, rain shaving electrical machine 5, by quick stall, can not be in extreme lower position because inertia makes rain shaving blade turn over; As rain shaving blade is not in extreme lower position (namely windscreen wiper extreme lower position switch 7 disconnects), windscreen wiper control unit 7 will control rain shaving electrical machine 5 and continue slow running, until when rain shaving blade is in extreme lower position, rain shaving electrical machine 5 quits work immediately.
(2) do not rain do not spray water washing yet time, if rain shaving blade is appointed be in extreme lower position, then no matter whether ignition lock 2 closes, and rain shaving electrical machine 5 all can not work; As rain shaving blade is not in extreme lower position, then no matter whether ignition lock 2 closes, and rain shaving electrical machine 5 all can slow running, until rain shaving blade is in extreme lower position, rain shaving electrical machine 5 quits work immediately.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
