Three-scraper flexible shaft type windscreen wiper with flexible wall supporting wiper connecting rod

Abstract

A three-scraper flexible shaft type windscreen wiper with a flexible wall supporting wiper connecting rod comprises a wiper motor, a wiper driving mechanism and a wiper. The windscreen wiper is characterized in that a wiper driving shaft includes a driven wiper driving shaft and a drive wiper driving shaft, a driven gear and a drive gear are arranged on the driven wiper driving shaft and the drive wiper driving shaft respectively, are connected through a flexible shaft and transmit torque, and a closed connecting rod swing arm driving mechanism is arranged on the drive gear. The wiper driving mechanism is of a closed structure, low in working noise, particularly suitable for complicated external environmental structures and remote driving and adaptable to different vehicle types, external influence is avoided, the shortcoming of burnout of the wiper motor due to external obstacles is avoided, interior noise is effectively reduced, internal comfort of a vehicle in running is improved, a wiper rubber strip is supported by a flexible wall and can be more effectively fitted with a windscreen, and the scraping efficiency of a three-scraper structure is three times that of a common single-scraper structure.

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
