Three-blade flexible wall mounted wiper linkage hydraulic oscillating wiper

Abstract

A three-scraper wiper connecting rod hydraulic swing windscreen wiper with flexible wall supporting comprises a windscreen wiper motor, a wiper driving mechanism and wipers 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 connecting rod and rocker arm driving mechanism is arranged on the driving gear and rack swing oil cylinder. The three-scraper wiper connecting rod 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 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 windshield wiper, which belongs to the field of automobile windshield wipers, in particular to a windshield wiper driven by a flexible pipeline hydraulic pressure. 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 eff...

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 rod hydraulic swing The wiper 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 wiped off quickly
