Description

Technical Field

[0001] The utility model relates to the technical field of windshield wipers, in particular to a windshield wiper device for an automobile. Background Art

[0002] Windshield wipers are a very common feature on cars. They are generally composed of two continuous speeds, fast and slow, intermittent and single speeds. The function of the wipers is to scrape off the rain on the surface of the glass, thus forming a uniform water film so that the light passing through the glass will not be refracted, thereby improving the driver's visibility and increasing driving safety.

[0003] The prior art discloses patent application number "CN202020185086.0", which is a car wiper device, including a scraper blade, a scraper frame, a front swing arm, a rear swing arm and a limit spring; the upper end of the scraper blade is clamped with the scraper frame, and a wing plate is provided above the scraper frame. By providing the wing plate, the sliding plate, the sleeve and the spring, the scraper blade floats when the vehicle is traveling at high speed. When the scraper blade is operating, the contact area between the scraper blade and the glass is reduced, the sliding smoothness of the scraper blade is improved, and the noise is reduced.

[0004] The automobile wiper device can only improve the sliding smoothness of the wiper blade. However, in actual use, since the automobile wiper device is generally fixed by a simple clip method, the automobile wiper device is not installed firmly enough, thereby reducing the stability of the automobile wiper device and affecting the scraping and washing effect of the automobile wiper device, making it inconvenient to use.
