Three-scraping-piece flexible wall supported wiper flexible shaft type windscreen wiper

Abstract

A three-scraping-piece flexible wall supported wiper flexible shaft type windscreen wiper comprises a wiper motor, a wiper driving mechanism and a wiper and is characterized in that a wiper drive shaft is divided into a driven wiper drive shaft and a driving wiper drive shaft, the driven wiper drive shaft and the driving wiper drive shaft are respectively provided with a driven gear and a driving gear, and the driven gear and the driving gear are connected through a flexible shaft and transfer torque. A forward and reverse rotating gear intermittent drive mechanism is arranged on the driving gear. The wiper driving mechanism of the windscreen wiper is of a closed structure, is low in noise during working, is especially suitable for a complicated external environment structure and remote transmission, can adapt to vehicles of different models and is not influenced by the outside, the defect that the wiper motor is burned down due to an external obstacle is avoided, interior noise is effectively reduced, the interior comfort of a vehicle in running is improved, a wiper rubber strip is supported by a flexible wall and can be well fit with a windscreen, and the efficiency of a three-scraping-piece structure is triple of the scraping efficiency 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 shaft. 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 c...

[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
