The windscreen wiper comprises a windscreen wiper and a detection module, wherein the windscreen wiper rotates around a fixed point on an automobile window, and the length of the windscreen wiper stretches and stretches according to the rotating angle of the windscreen wiper, so that the windscreen wiper covers the automobile window at any rotating angle position; the detection module is electrically connected with the windscreen wiper and is used for detecting the rotation angle of the windscreen wiper, determining the position of the windscreen wiper, and when the number of the windscreen wipers is one, the fixed point of the windscreen wiper is arranged at the midpoint of the window of the automobile and rotates around the fixed point; when the number of the windshields is two, the fixed points of the first windshield wiper and the second windshield wiper are arranged on the automobile window at intervals and rotate around the fixed points of the first windshield wiper and the second windshield wiper respectively.
The novel windscreen wiper of application number 201210521170.5, including scraping strip and gum cover, still include the track, the track has two, sets up respectively in the upper and lower both ends of door window, all is provided with miniature mobile motor on every track, the gum cover is connected on miniature mobile motor, scrapes the strip setting between two gum covers. All rainwater on the car window can be scraped by arranging a track to enable the scraping strip to move left and right on the car window. The miniature mobile motor is arranged to facilitate the scraping strip to move on the track, and the water outlet enables rainwater accumulated in the track to be smoothly discharged, so that the damage of the windscreen wiper caused by the accumulation of rainwater is avoided.
The driving power of the two types of windscreen wipers is insufficient, and the wiper strip is easy to break.
