Windscreen wiper with two scraping sheets, flexible walls, windshield wiper body and flexible shaft

Abstract

A windscreen wiper with two scraping sheets, flexible walls, a windshield wiper body and a flexible shaft comprises a windshield wiper motor, a windshield wiper driving mechanism and the windshield wiper body, and is characterized in that a windshield wiper driving shaft is divided into a driven windshield wiper driving shaft body and a driving windshield wiper driving shaft body, the driven windshield wiper driving shaft body and the driving windshield wiper driving shaft body are provided with a driven gear and a driving gear respectively, the driven gear is connected with the driving gear through the flexible shaft, the driven gear and the driving gear are used for transmitting torque, and the driving gear is provided with a forward and reverse gear intermittent transmission mechanism. The windshield wiper driving mechanism is of a closed structure, is low in noise during work, is especially suitable for external environments of complex structures and remote transmission, can adapt to different vehicle types, is not influenced by exteriors, overcomes the defect that external obstacles cause burndown of the windshield wiper motor, effectively lowers noise in a vehicle and improves internal comfort when the vehicle runs; windscreen wiper rubber strips are supported by the flexible walls and can be better attached to windshield glass, and scraping efficiency of a double-scraping-sheet structure is twice that of common single-scraping-sheet structures.

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
