Flexible wall bearing wiper linkage blade hydraulic wiper

Abstract

A flexible wall supporting windshield wiper connecting rod vane hydraulic windshield wiper comprises a wiper motor and a wiper driving shaft, and is characterized in that two vane swing oil cylinders are communicated through a hydraulic oil pipe and transmit torque; the driving vane swing oil cylinder is provided with a connecting rod swing arm driving mechanism. The flexible wall supporting windshield wiper connecting rod vane hydraulic windshield wiper has the advantages that a wiper driving mechanism of the windshield wiper is driven hydraulically through a flexible pipeline, the transmission torque is large, the size is small, and response is fast; as hydraulic transmission is achieved through the flexible pipeline, the windshield wiper is slightly limited by the structure when installed, is of a fully closed structure, is low in noise when working, is particularly suitable for complex and long-distance transmission of an external environment, is not affected by the outside, avoids the defect that the wiper motor is burnt out due to an external barrier, effectively reduces noise in a car and improves the comfort inside the car in the running process; a wiper rubber strip is supported by a flexible wall and can be better attached to windshield glass.

Description

Technical field [0001] The invention relates to a wiper drive mechanism, which belongs to the field of automobile wipers, in particular to a wiper driven by 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, and it is easy to ca...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the disadvantages that the existing wiper drive mechanism is noisy when it is working, and the connecting rod transmission mechanism is open, which is greatly affected by the outside. If it is blocked by an obstacle during work, it will easily cause the burnout of the wiper motor; the wiper rubber The wiper blade under the rigid support is difficult to adapt to the change of the windshield glass surface, and the wiping efficiency is low in the scraping process, and it is not easy to quickly wipe off the disadvantages. The invention provides a flexible wall support wiper connecting rod blade Hydraulic wiper, it is a completely closed structure, low noise, large transmission torque, quick response and not affected by the external environment, the wiper rubber strip can be better bonded to the windshield
