Flexible Wall Bearing Wiper Link Hydraulic Oscillating Wiper

Abstract

A hydraulic swing windscreen wiper with a flexible wall supporting wiper connecting rod comprises a wiper motor, a wiper driving mechanism and a wiper. The hydraulic swing windscreen wiper is characterized in that two gear rack swing cylinders are communicated through a hydraulic oil pipe and transmit torque, and a connecting rod swing arm driving mechanism is arranged on a driving gear rack swing cylinder. The hydraulic swing windscreen wiper has the advantages that the wiper driving mechanism of the windscreen wiper is hydraulically driven by a flexible pipeline, high in transmitted torque, small in size and rapid in response, structural limitation is less in mounting owing to hydraulic driving of the flexible pipeline, the windscreen wiper is of a completely closed structure, low in working noise and particularly suitable for complicated external environmental structures and remote driving, external influence is avoided, the shortcoming of burnout of the wiper motor due to external obstacles is avoided, interior noise is effectively reduced, internal comfort of a vehicle in running is improved, and a wiper rubber strip is supported by a flexible wall and can be more effectively fitted with a windscreen.

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. It is difficult for the wiper under the rigid support to adapt to the change of the surface of the windshield. During the scraping process, the wiping efficiency is low, it is not easy to scrape quickly, a...

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 The scraper under the rigid support is difficult to adapt to the change of the surface of the windshield, and the scraping efficiency is low in the scraping process, and it is not easy to scrape quickly. The invention provides a hydraulic swing wiper with a flexible wall support wiper link , it is a completely closed structure with low noise, large transmission torque, quick response and not affected by the external environment, and the wiper rubber strip can be better bonded to the windshield
