Three-scraper wiper hydraulic swing windscreen wiper with flexible wall supporting

Abstract

A three-scraper wiper hydraulic swing windscreen wiper with flexible wall supporting comprises a windscreen wiper motor, a wiper driving mechanism and a wiper and is characterized in that two gear and rack swing oil cylinders are communicated through a hydraulic oil pipe, torque is transmitted between the two gear and rack swing oil cylinders through the hydraulic oil pipe, and a forward and reverse rotation gear intermittent transmission mechanism is arranged on the driving gear and rack swing oil cylinder. The three-scraper wiper hydraulic swing windscreen wiper has the advantages that as flexible pipeline hydraulic transmission is adopted in the wiper driving mechanism of the windscreen wiper, structural limit is small when the windscreen wiper is installed; as the windscreen wiper is of a completely 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 and not affected by external factors, 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 a flexible wall and therefore can fit windscreen better, and the scraping efficiency of the three-scraper structure is three times that of a general single scraper.

Description

Technical field [0001] The invention relates to a wiper drive mechanism, which belongs to the field of automobile wipers, in particular to a wiper driven by flexible pipeline hydraulic pressure. 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 eas...

[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
