Double-scraper flexible shaft type windscreen wiper with flexible walls and wiper connecting rod

Abstract

A double-scraper flexible shaft type windscreen wiper with flexible walls and a wiper connecting rod comprises a windscreen wiper motor, a wiper driving mechanism and wipers and is characterized in that a wiper driving shaft is divided into a driven wiper driving shaft and a driving wiper driving shaft, a driven gear and a driving gear are arranged on the driven wiper driving shaft and the driving wiper driving shaft, the driven gear and the driving gear are connected through a flexible shaft, and torque is transmitted between the driven gear and the driving gear through the flexible shaft. A closed connecting rod and rocker arm driving mechanism is arranged on the driving gear. As the wiper driving mechanism of the windscreen wiper is of a closed structure, noise is low when the windscreen wiper works, the windscreen wiper is particularly suitable for the complex external environmental structure and long-distance transmission, the defect that the windscreen wiper motor is burnt due to external obstacles is overcome, the noise in a vehicle is effectively lowered, and the comfort in the vehicle is improved when the vehicle operates; windscreen wiper rubber strips are supported by the flexible walls and therefore can fit windscreen better, and the scraping efficiency of the double-scraper structure is two times that of a general single scraper.

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
