Flexible wall supporting windshield wiper connecting rod wire wheel type windshield wiper with three scraping pieces

Abstract

A flexible wall supporting windshield wiper connecting rod wire wheel type windshield wiper with three scraping pieces comprises a wiper motor, a wiper driving mechanism and a wiper, and is characterized in that a wiper driving shaft comprises a driven wheel wiper driving shaft and a driving wheel wiper driving shaft which are arranged in a driven wheel wiper driving shaft hole of a driven wheel fixing seat and a driving wheel wiper driving shaft hole of a driving wheel fixing seat respectively; the driven wheel wiper driving shaft and the driving wheel wiper driving shaft are provided with a driven winding wheel and a driving winding wheel respectively, the driven winding wheel and the driving winding wheel are connected through a flexible rope and transmit torque, and the driving winding wheel is provided with a closed type connecting rod swing arm driving mechanism. The connecting rod line wheel type wiper driving mechanism of the windshield wiper is of a closed structure, is particularly suitable for complex and long-distance transmission of an external environment, is not affected by the outside and avoids the defect that the wiper motor is burnt out due to an external barrier. A wiper rubber strip is supported by a flexible wall and can be better attached to windshield glass. The scraping efficiency of the three-scraping-piece structure is three times that of a common single scraping piece.

Description

Technical field [0001] The invention relates to a wiper, which belongs to the field of automobile wipers, in particular to a wiper driven by a flexible wire. Background technique [0002] At present, most of the wiper driving mechanisms of wipers on the market are continuous drive, which makes a lot of noise during operation. Moreover, the continuous drive mechanism is open and is greatly affected by external influences. Cause the wiper motor to burn out; the support platform of the wiper blade on the market is usually rigid, because the windshield glass is a curved surface shape, coupled with manufacturing reasons and wear and tear during use, the surface of the windshield glass is irregular and defective. The scraper under the rigid support is difficult to adapt to the change of the surface of the windshield, and there is only one scraper, the scraping degree is low in the scraping process, the scraping efficiency is poor, it is not easy to scrape quickly, it is easy to ca...

[0002] At present, most of the wiper driving mechanisms of wipers on the market are continuous drive, which makes a lot of noise during operation. Moreover, the continuous drive mechanism is open and is greatly affected by external influences. Cause the wiper motor to burn out; the support platform of the wiper blade on the market is usually rigid, because the windshield glass is a curved surface shape, coupled with manufacturing reasons and use process wear and other reasons, resulting in irregular defects on the windshield glass surface. The scraper under the rigid support is difficult to adapt to the change of the windshield glass surface, and there is only one scraper, the scraping degree is low in the scraping process, the scraping efficiency is poor, it is not easy to scrape quickly, it is easy to cause blurred vision, and it is difficult for driving. to safety hazard
