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 lead to the burnout of the wiper motor. The present invention provides A hydraulic swing wiper drive mechanism, which is a completely closed structure, with low noise, large transmission torque, quick response and not affected by the external environment

Abstract

The invention discloses a windshield wiper drive mechanism based on hydraulic swing. The windshield wiper drive mechanism based on hydraulic swing comprises a windshield wiper motor and a windshield wiper drive shaft and is characterized in that two gear rack swing oil cylinders are communicated and transmit torque through a hydraulic oil pipe, and the driving gear rack swing oil cylinder is provided with a positive and reverse rotation gear intermittent transmission mechanism. The windshield wiper drive mechanism based on hydraulic swing has the advantages that flexible duct hydraulic transmission is adopted in the windshield wiper driver mechanism of a windshield wiper, so the windshield wiper driver mechanism is large in transmission torque, small in size and quick in response; due to the flexible duct hydraulic transmission, the limitation for the windshield wiper driver mechanism during installation is small; in addition, due to a completely sealed structure, the windshield wiper driver mechanism is low in noise during working, and is especially suitable for external environments with complicated structures and long-distance transmission; the windshield wiper driver mechanism is not affected by the outside, overcomes the defects that the windshield wiper motor is burnt out due to external obstacles, effectively reduces in-car noise and improves inside comfort of a vehicle during operation.

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 drive mechanism driven by a flexible pipeline hydraulically. 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. Caused the wiper motor to burn out. Contents of the invention [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 lead to the burnout of the wiper motor. The present invention provides A hydraulic swing wiper drive mechanism, which is a completely closed structure, has low nois...
