Abstract
A kind of fully automatic electronic switch widnscreen wiper, by the rainfall inductor, electronic switch, electric wiper and fork rubber brush are formed.During use, electronic switch starts or stops Windshield Wiper automatically, and changes Windshield Wiper fork hunting frequency automatically according to the rainfall signal that the rainfall inductor transmits.Thereby avoided the problem that traditional Windshield Wiper frequency is single and M/C is frequent.
Description
The invention belongs to car electrics control field.
The used automobile water wiper of municipalization so far, all be by the driver according to rainy no rain, the rainfall size is handled the action of source switch control Windshield Wiper.During use, energized, Windshield Wiper fork rubber brush reciprocally swinging.Windshield Wiper control at present divides fast, slow again and regularly three kinds, any control method no matter, all require automobilist's one side under the rainfall situation of change drive one side frequently manually be switched on or switched off Windshield Wiper power supply, the unavoidable like this energy that will disperse the driver to drive.When not needing higher hunting frequency because of rain is little, the frequent swing of Windshield Wiper also affects the attention that the driver drives.The present invention is directed to the problems referred to above, proposed a kind of vision that replaces the driver by rainfall inductor and electronic switch.Thinking reflection and Motor ability, rainfall inductor are discerned rainy no rain, after the rainfall size, by the processing of electronic switch, start or stop Windshield Wiper automatically and change Windshield Wiper fork hunting frequency automatically, need not manual frequencies operations.So not only alleviated the labour intensity that automobilist's rainy day drives a vehicle, ensured that the driving attention concentrates the prior measures that reduces the rainy day motor traffic accidents that provided.
The present invention, is linked with the electronic switch (2) of signal being judged and being handled as sample of signal by rainfall inductor (1).After the rainfall inductor receives rainfall not timing stochastic signal, the pulse gate master who opens electronic switch shakes impulse singla through shaping and amplification rear drive electric wiper (3), to realize pressing the rainfall size, start or stop automatically and change hunting frequency certainly with the electric wiper fork rubber brush (4) that links.The swing of Windshield Wiper fork is held time and is controlled by the electronic switch pulse time.Guaranteeing in each pulse time that the fork rubber brush is finished once scrapes water week after date fork rubber brush and returns initial point.With when the rainfall inductor contact, remove this rainwater signal in Windshield Wiper fork rubber brush swing, wait next rainwater pulse arrival after, swing once more.
The rainfall inductor adopts the contactless type metal construction.Be installed on the shield glass.The main portion of electronic switch adopts digital integrated circuit to combine, with reduced volume, and expendable weight, guaranteeing can reliable and stable work under the condition of automobile frequency vibration.Housing adopts metal or plastics.The present invention is except that rainfall inductor and electronic switch, and electric wiper and fork rubber brush all are conventional, no specific (special) requirements.
Below in conjunction with accompanying drawing implementation example of the present invention is described in detail.
