Three-scraping-piece flexible wall round hole internal-supported wiper blade hydraulic type windscreen wiper

Abstract

A three-scraping-piece flexible wall round hole internal-supported wiper blade hydraulic type windscreen wiper comprises a 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 and transfer torque, and a forward and reverse rotating gear intermittent drive mechanism is arranged on the driving blade swing oil cylinder. The three-scraping-piece flexible wall round hole internal-supported wiper blade hydraulic type windscreen wiper has the advantages that the wiper driving mechanism of the windscreen wiper performs hydraulic drive through a flexible pipe, is large in transfer torque, is small in structural limitation during installation, is completely of a closed structure, 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, a wiper rubber strip is supported by a flexible wall and can be well fit with a windscreen, and 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, 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...

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
