Abstract

A hydraulic windscreen wiper driving mechanism provided with connecting rods and blades comprises a wiper motor and windscreen wiper driving shafts, and is characterized in that two blade swing oil cylinders are communicated through a hydraulic oil pipe and transmit torque; a connecting rod rocker arm driving mechanism is arranged on a driving blade swing oil cylinder. The hydraulic windscreen wiper driving mechanism has the benefits as follows: the windscreen wiper driving mechanism of a windscreen wiper is driven hydraulically by a flexible pipeline, the transmitted torque is high, the size is small, response is rapid, structural limit is little during mounting because of hydraulic driving of the flexible pipeline, the mechanism is a completely closed structure, and the noise is low during work, so that the driving mechanism is particularly suitable for driving with complicated external environmental structure and long distance and is not affected by the 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 traveling of the vehicle is improved.

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 continuous drive, which makes a lot of noise during operation. Moreover, the continuous drive mechanism is open and is greatly affected by external influences. 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 that the continuous driving mechanism is open and is greatly affected by the outside. If it is blocked by an obstacle during work, it will easily cause the wiper motor to burn out. The present invention provides A connecting rod blade hydraulic wiper drive mechanism is a completely closed structure with low noise, large transm...
