Three-scraper flexible wall inner support wiper hydraulic swing wiper

Abstract

A three-scraping-piece flexible wall round hole internal-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 three-scraping-piece flexible wall round hole internal-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 small in structural limitation during installation, is completely of a closed structure, is low in noise during working, is especially suitable for a complicated external environment structure and remote transmission 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, a wiper rubber strip is supported by a flexible wall and can be well fit with a windscreen, and efficiency of a three-scraping-piece structure is triple of the scraping efficiency of a common single scraping piece.

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. The scraper under the rigid support is difficult to adapt to the change of the surface of the windshield, and there is only one scraper, the scraping degree is low in the scraping process, the scraping efficiency is poor, it...

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 It is difficult for the wiper blades under the rigid support to adapt to the change of the windshield glass surface. In the process of scraping, the wiping efficiency is low, and it is not easy to quickly wipe clean. The invention provides a three-blade flexible wall support wiper hydraulic swing The wiper is a completely closed structure with low noise and is not affected by the external environment; the wiper rubber strip can better fit the windshield and can be wiped off quickly
