Three-Blade Flexible Wall Support Wiper Blade Hydraulic Wiper

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, which belongs to the field of automobile wipers, in particular to a hydraulically driven wiper. Background technique [0002] At present, most of the wiper driving mechanisms of wipers on the market are connecting rod transmission, which makes a lot of noise during operation, and the connecting rod transmission mechanism is open, which is greatly affected by the outside. 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...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the noise when the existing wiper drive mechanism is working, and the connecting rod transmission mechanism is open, it is greatly affected by the outside. If it encounters obstacles during work, it will easily cause the wiper motor to burn out; the wiper rubber strip It is difficult for the wiper blade under the rigid support to adapt to the change of the windshield glass surface, and the wiping efficiency is low during the scraping process, and it is not easy to quickly wipe clean. The invention provides a three-blade flexible wall support wiper blade hydraulic wiper , it is a completely closed structure with low noise and is not affected by the external environment; the wiper rubber strip can better fit the windshield and can be quickly wiped off
