Flexible wall supported wiper hydraulic swing windscreen wiper

Abstract

A flexible wall supported wiper hydraulic swing windscreen wiper comprises a wiper motor, a wiper driving mechanism and a wiper and is characterized in that two gear rack swing oil cylinders are communicated through a hydraulic oil pipe and transfer torque, and a forward and reverse rotating gear intermittent drive mechanism is arranged on the driving gear rack swing oil cylinder. The flexible wall supported wiper hydraulic swing windscreen wiper has the advantages that the wiper driving mechanism of the windscreen wiper performs hydraulic drive through a flexible pipe, is large in transfer torque, small in size and quick in response, is small in structural limitation during installation due to the fact that the hydraulic drive by means of the flexible pipe is adopted, is completely of a closed structure, is low in noise during working, is especially suitable for a complicated external environment structure and remote transmission, can adapt to vehicle of different models and is not influenced by the outside, the defect that the wiper motor is burned down due to an external obstacle is avoided, interior noise is effectively reduced, the interior comfort of a vehicle in running is improved, and a wiper rubber strip is supported by a flexible wall and can be well fit with a windscreen.

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 continuous drive, which makes a lot of noise during operation. Moreover, the continuous drive mechanism is open and is greatly affected by external influences. 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 cause blurred...

Problems solved by technology

[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. 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 windshield glass surface. During the scraping process, the wiping efficiency is low, it is not easy to quickly wipe clean, and it is easy to cause blurred vision and bring safety hazards to driving.
