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 blade hydraulic 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

A hydraulic windshield wiper driving mechanism provided with blades comprises a wiper motor and windshield wiper driving shafts, and is characterized in that two blade swing oil cylinders are communicated through a hydraulic oil pipe and transfer torque; a positive and reverse rotating gear intermittent driving mechanism is arranged on a driving blade swing oil cylinder. The hydraulic windshield wiper driving mechanism has the benefits as follows: the windshield wiper driving mechanism of a windshield wiper adopts hydraulic driving of a flexible pipeline, has large transmission torque and small size and responds quickly; by means of the hydraulic driving of the flexible pipeline, structural limit during mounting is little, and the mechanism is a completely closed structure, has low noise during work, is particularly suitable for driving with complicated outside environmental structure and far-distance driving and is not influenced by outside; the defect that the wiper motor is burnt due to outside barriers is overcome, noise in a vehicle is reduced effectively, and inside comfort during driving of the vehicle is improved.

Description

Technical field [0001] The invention relates to a wiper drive mechanism, belonging to the field of automobile wipers, in particular to a wiper drive mechanism of a flexible pipe hydraulic transmission. Background technique [0002] At present, most of the wiper drive mechanisms of wipers on the market are connected by connecting rods, and the noise during operation is relatively large. In addition, the connecting rod transmission mechanism is open type, which is greatly affected by external influences. It may be easily blocked by obstacles during operation. Causes the wiper motor to burn out. Summary of the invention [0003] In order to overcome the disadvantages that the existing wiper drive mechanism is noisy when it works, and the connecting rod transmission mechanism is open, which is greatly affected by the outside, and if it encounters obstacles during work, it will easily cause the wiper motor to burn out, the present invention provides A blade hydraulic wiper drive mecha...
