The wiper and the wiper water-spraying motor are widely applied to various vehicles such as cars, passenger cars, trucks and the like. The automobile windscreen wiper has the advantages that the quality requirement is long in service life, severe working conditions such as impact load and overload and low cost are met, the reliability and safety of a circuit structure are guaranteed, and the automobile windscreen wiper is provided with a water sprayer to prevent a wiper blade from being scraped at the window glass of the automobile and damaging the wiper blade.
When the window glass of the automobile is dirty and the sight of a driver is influenced, the water sprayer is started. The working process of the existing water sprayer is as follows: when the water sprayer is started, the windscreen wiper sometimes works first, then the wiper blade is dry-scraped in front, the water sprayer sprays water at the back, the aim of cleaning the window glass of the automobile by spraying water cannot be fulfilled, and the service life of the wiper blade is shortened. When the wiper blade scrapes backwards, the water sprayer sprays water or starts to spray water, so that the water is wasted and the cleaning effect cannot be achieved.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the working process to current wiper and sprinkler exists the aforesaid not enough and provide an automatic water jet equipment of wiper, it is when will wasing car window glass, wiper motor work when opening the sprinkler water spray, sprinkler spun water will be together with the wiper doctor-bar, wash car window glass, when the wiper doctor-bar gyration, the sprinkler motor is out of work, reached and washed car window glass and still reached the purpose of using water wisely when protecting the wiper doctor-bar.
The utility model discloses the technical problem that will solve can realize through following technical scheme:
an automatic water spraying device of a windscreen wiper comprises the windscreen wiper and a water sprayer, wherein the windscreen wiper comprises a windscreen wiper motor and a windscreen wiper output gear driven by the windscreen wiper motor, the water sprayer comprises a water sprayer motor, a high-speed gear and a low-speed gear of the windscreen wiper motor are connected with the positive electrode of a power supply through a high-speed switch and a low-speed switch respectively, and the negative electrode of the windscreen wiper motor is grounded through a windscreen wiper motor pulse switch; the windscreen wiper is characterized by also comprising an arc copper sheet fixed on the output gear of the windscreen wiper; when the arc-shaped copper sheet rotates in a first area along with the wiper output gear, a negative electrode of a power supply, a return end of a wiper motor and a negative electrode end of a water sprayer motor are in sliding electrical contact with the arc-shaped copper sheet; when the arc-shaped copper sheet rotates in the second area along with the wiper output gear, the negative electrode of the power supply, the return end of the wiper motor and the negative electrode end of the water sprayer motor are all out of electrical contact with the arc-shaped copper sheet.
In a preferred embodiment of the present invention, the first area is an area where the wiper blade of the wiper moves from the lowest end position to the highest end position, i.e. a wiping area of the wiper blade; the second area is an area where the wiper blade in the windscreen wiper moves from the highest end position to the lowest end position, namely a wiper blade rotation area.
In a preferred embodiment of the present invention, a water spraying motor pulse switch is connected in series to the negative terminal of the water sprayer motor.
In a preferred embodiment of the present invention, the central angle of the arc-shaped copper sheet is approximately 180 °.
The working principle of the utility model is as follows: when a scraping blade in the windscreen wiper moves from the lowest end position to the highest end position, namely the scraping blade in the windscreen wiper performs wiping work, as the negative electrode of the power supply, the return end of the windscreen wiper motor and the negative end of the water sprayer motor are in sliding electrical contact with the arc-shaped copper sheet, the water sprayer motor is electrified, and the water sprayer sprays water. When the scraping blade in the windscreen wiper moves from the highest end position to the lowest end position, namely when the scraping blade in the windscreen wiper rotates, the negative pole of the power supply, the return end of the windscreen wiper motor and the negative pole end of the water sprayer motor are all separated from the arc-shaped elastic sheet, the water sprayer motor is not electrified, and the water sprayer does not spray water.
The utility model discloses utilize the lot to fix on wiper output gear and follow the control that wiper output gear turned round arc copper sheet realized water jet motor operating condition ingeniously, its structure is simpler, and the cost is lower.
