Three-scraping-piece flexible wall supported wiper connecting rod blade hydraulic type windscreen wiper

Abstract

A three-scraping-piece flexible wall supported wiper connecting rod blade hydraulic type windscreen wiper comprises a wiper motor and a wiper drive shaft and is characterized in that two blade swing oil cylinders are communicated through a hydraulic oil pipe and transfer torque, and a connecting rod rocker arm drive mechanism is arranged on the driving blade swing oil cylinder. The three-scraping-piece flexible wall supported wiper connecting rod blade hydraulic type windscreen wiper that a wiper driving mechanism of the windscreen wiper performs hydraulic drive through a flexible pipe, is large in transfer torque, small in size and quick in response, is small in structural limitation during installation due to the fact that the hydraulic drive by means of the flexible pipe is adopted, is completely of a closed structure, is low in noise during working, is especially suitable for a complicated external environment structure and remote transmission and is not influenced by the outside, the defect that the wiper motor is burned down due to an external obstacle is avoided, interior noise is effectively reduced, the interior comfort of a vehicle in running is improved, a wiper rubber strip is supported by a flexible wall and can be well fit with a windscreen, and the efficiency of a three-scraping-piece structure is triple of the scraping efficiency of a common single scraping piece.

Description

Technical field [0001] The invention relates to a wiper drive mechanism, belonging to the field of automobile wipers, in particular to a wiper driven by a flexible pipeline hydraulically. 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 ...

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
