Three-blade flexible wall round hole supports wiper linkage hydraulic swing wiper

Abstract

A three-scraping-piece flexible wall round hole internal-supported wiper connecting rod 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 connecting rod rocker arm drive mechanism is arranged on the driving gear rack swing oil cylinder. The three-scraping-piece flexible wall round hole internal-supported wiper connecting rod 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, and a wiper rubber strip is supported by a flexible wall and can be well fit with a windscreen, and the 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 blade, which belongs to the field of automobile wiper blades, in particular to a wiper blade driven by a flexible pipeline hydraulic pressure. Background technique [0002] At present, the wiper drive mechanism of wiper blades on the market is mostly connected by connecting rod, and the noise during operation is relatively large. Moreover, the connecting rod transmission mechanism is open type, which is greatly affected by external influences. It is easy to be blocked by obstacles during operation. Causes the wiper motor to burn out; the support table of the wiper strip on the market is usually rigid. Because the windshield glass is curved, and the manufacturing reasons and the wear and tear of the use process, the surface of the windshield has irregular defects. The wiper blade under the rigid support is difficult to adapt to the changes of the windshield glass surface, and there is only one wiper blade. During the scraping...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the noise when the existing wiper drive mechanism is working, and the connecting rod transmission mechanism is open, it is greatly affected by the outside. If it encounters obstacles during work, it will easily cause the wiper motor to burn out; the wiper rubber strip It is difficult for the wiper blade under the rigid support to adapt to the change of the surface of the windshield glass. In the process of scraping, the wiping efficiency is low, and it is not easy to quickly wipe clean. Rod hydraulic swing wiper, it is a completely closed structure, low noise, and not affected by the external environment; the wiper rubber strip can better fit the windshield, and can quickly wipe off
