Description

Windscreen wiper

Technical Field

The utility model relates to the technical field of vehicle accessories, in particular to a windscreen wiper.

Background

Wiper blades are designed to wipe the window glass by swinging through a vacuum driven pump connection, which has been used until now. The more elaborate and the larger the industry is, the more obvious the windscreen wiper is, but the more obvious the drawback is when the windscreen wiper is designed: the windscreen wiper can leave more places which cannot be scraped when swinging on square glass, however, at the beginning of the design of the windscreen wiper, road conditions (fewer pedestrians are in a vehicle and shorter traffic lights) are simpler, places which cannot be scraped on the front shield of an automobile do not have larger potential safety hazards even if larger visual blind areas exist but the road conditions are simple, and the front shield position beside the A column side does not need to be observed for quick non-motor vehicles and various signal lamps, so that the windscreen wiper can fully adapt to the driving environment and aesthetic ideas at that time. However, as the road conditions become more and more complex, the windscreen wiper does not improve too much in such a long time, and a large blind area of view still occurs in a place where the windscreen wiper on the front of the automobile cannot be scraped.
