Three-scraping-plate flexible wall round hole inner support windshield wiper flexible shaft type windshield scraper

Abstract

Provided is a three-scraping-plate flexible wall round hole inner support windshield wiper flexible shaft type windshield scraper. The windshield scraper comprises a windshield scraper motor, a windshield wiper drive mechanism and a windshield wiper, and is characterized in that a windshield wiper drive shaft comprises a driven windshield wiper drive shaft and a driving windshield wiper drive shaft, the driven windshield wiper drive shaft and the driving windshield wiper drive shaft are provided with a driven gear and a driving gear respectively, the driven gear and the driving gear are connected through a flexible shaft and transmit torque, and the driving gear is provided with a forward and backward rotation gear intermittent transmission mechanism. The windshield scraper drive mechanism is of a closed structure, low in operating noise, especially suitable for transmission in complex structures of external environments and long-distance transmission, capable of adapting to different vehicle types and free of external influences, avoids the defect that the windshield scraper motor is burnt out due to external barriers, effectively lowers noise in a vehicle and improves the interior comfort in running of the vehicle, a windshield scraper rubber strip is supported by flexible walls and can be better attached to windshield glass, and the scraping efficiency of the three-scraping-plate structure is three times that of a single common scraping plate.

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
