Abstract
The utility model relates to an automatic vehicle window wiper, which comprises a vehicle windshield, an engine, two wiper blades and driving units positioned on the engine and the wiper blades, characterized in that a raindrop sensor is arranged on the windshield and the raindrop sensor is wired with the engine. The window wiper in the utility model can regulate the swing state immediately according to the size and intensity of the raindrops so as to avoid the situations of swinging too fast or too slow and has the advantages of manpower-free operation, high sensitivity, easy operation and improvement of driving safety.
Description
Technical field
The utility model belongs to a kind of Windshield Wiper of windshield.
Background technology
Traditional vehicle glass Windshield Wiper mostly is the version that adopts hand switch, manual stepping step speed regulation, in use by the driver according to the swing state of rainfall situation by manual control scraping blade, there is following shortcoming in aforesaid way: 1, because when rainy, blurred vision, the driver not only needs to concentrate on to drive, also need frequently to divert one's attention to monitor Windshield Wiper, and vacate a hand frequently and control Windshield Wiper, influence driving safety; 2, the swing state of scraping blade has property time lag, and promptly scraping blade can not start swing immediately when it rained just now; Or when rain is heavier and heavier scraping blade can not to follow more pendulum in real time fast more, cause the scraping blade swing speed to cross low inadequately and can't scrape water neatly; Or rain to descend more hour scraping blade not follow immediately more slack-off, cause the scraping blade swing speed too high inadequately and hinder driver's seat.Therefore the swing state of scraping blade is compared with the rainwater state, and often the life period hysteresis quality can't make the preceding visual field of driver eye remain on possible optimum regime always.3, because rainfall size and dense degree are stepless, and the motor of existing Windshield Wiper adopts the motor of step speed regulation, generally has only the speed class two or three, thereby can't accurately adjust the swing speed of scraping blade according to rainfall size and dense degree.
Summary of the invention
The purpose of this utility model is to be to overcome above-mentioned shortcoming and a kind of full automatic car glass Windshield Wiper is provided, and it can according to the raindrop size or dense degree is instant changes swing state automatically, and does not need by manual operation, strengthens the safety of driving.
For realizing above purpose, full automatic car glass Windshield Wiper of the present utility model comprises windshield, motor and two scraping blades, also be provided with transmission device between motor and two scraping blades, its principal feature is, Raindrop sensor also is installed on windshield, and Raindrop sensor is electrically connected to motor.
Realization above-mentioned purpose scheme preferably is: this Windshield Wiper also is provided with microcomputer controller, and Raindrop sensor is electrically connected to microcomputer controller, is connected to motor by microcomputer controller again.
Realize that the better scheme of above-mentioned purpose is: described motor is a stepless speed-regulating motor.
The utlity model has following advantage and effect:
1, Windshield Wiper of the present utility model adds Raindrop sensor, can be according to having or not raindrop to start rain brush automatically, and can be according to the intermittent time length and the frequency of the instant automatically regulating scraping blade swing of rainfall size, avoid occurring the scraping blade swing too soon or too slow situation.
2,, can accurately regulate the swing speed of scraping blade according to rainfall size and dense degree owing to adopt stepless speed-regulating motor.
3, the driver is completely free of control the burden of Windshield Wiper, does not need driver's M/C, need not disperse driver's energy, more help strengthening drive safety.
4, the scraping blade swing speed can real-time regulated, can the life period hysteresis quality, guarantee that the visual field before the driver eye is in possible optimum regime always.
5, highly sensitive, easy to use, can be applicable on any type of vehicle.
Description of drawings
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model.
The specific embodiment
Full automatic car glass Windshield Wiper shown in Figure 1 comprises two stepless speed-regulating motors 1 and two rain brush, two rain brush are installed on the windshield 4, every rain brush has a scraping blade 21 and a cover swing arm 22, every motor drives a rain brush by 3 corresponding connections an of sets of transmission mechanism, also be provided with Raindrop sensor 5 at windshield 4, this Windshield Wiper also is provided with microcomputer controller, and Raindrop sensor 5 is connected to the control circuit of motor by microcomputer controller.Instant self-regulation motor rotating speed of signal that microcomputer controller transmits according to Raindrop sensor 5 and frequency, pitch time, thereby the intermittent time length and the frequency of the swing of control scraping blade avoid occurring the scraping blade swing too soon or too slow situation.
Microcomputer controller in the utility model can adopt integrated circuit modules or adopt micro controller system etc.
Claims (3)
