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

Abstract

A three-scraper wiper blade hydraulic windscreen wiper with flexible wall supporting comprises a windscreen wiper motor, a wiper driving mechanism and a wiper and is characterized in that two blade swing oil cylinders are communicated through a hydraulic oil pipe, torque is transmitted between the two blade swing oil cylinders through the hydraulic oil pipe, and a forward and reverse rotation gear intermittent transmission mechanism is arranged on the driving blade swing oil cylinder. The three-scraper wiper blade hydraulic windscreen wiper has the advantages that as flexible pipeline hydraulic transmission is adopted in the wiper driving mechanism of the windscreen wiper, the transmitted torque is large, and structural limit is small when the windscreen wiper is installed; as the windscreen wiper is of a completely closed structure, the windscreen wiper is particularly suitable for the complex external environmental structure and long-distance transmission and not affected by external factors, and the defect that the windscreen wiper motor is burnt due to external obstacles is overcome; windscreen wiper rubber strips are supported by flexible walls 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, belonging to the field of automobile wipers, in particular to a wiper of hydraulic transmission. Background technique [0002] At present, most of the wiper drive mechanisms of wipers on the market are driven by continuous drive, which is noisy during operation. Moreover, the drive mechanism of continuous drive is open, which is greatly affected by external influences. If it encounters obstacles during operation, it is easy to block Cause the wiper motor to burn out; the support platform of the wiper blade on the market is usually rigid, due to the curved shape of the windshield glass, and the manufacturing reasons and the wear process of the use process cause irregular defects on the surface of the windshield glass. The scraper under the rigid support is difficult to adapt to the changes of the windshield glass surface, and there is only one scraper, which has low scraping degree and poor scraping efficiency during th...

AI Technical Summary

Problems solved by technology

[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
