Three-blade flexible wall round hole inner support connecting rod wire wheel type wiper

Abstract

A three-scraping-piece flexible wall round hole internal-supported connecting rod wire wheel type windscreen wiper comprises a wiper motor, a wiper driving mechanism and a wiper and is characterized in that a wiper drive shaft is divided into a driven wheel wiper drive shaft and a driving wheel wiper drive shaft, and the driven wheel wiper drive shaft and the driving wheel wiper drive shaft are respectively arranged in a driven wheel wiper drive shaft hole formed in a driven wheel fixing seat and a driving wheel wiper drive shaft hole formed in a driving wheel fixing seat. A driven winding wheel and a driving winding wheel are respectively arranged on the driven wheel wiper drive shaft and the driving wheel wiper drive shaft, are connected through a flexible rope and transfer torque. A closed connecting rod rocker arm driving mechanism is arranged on the driving winding wheel. The connecting rod wire wheel type wiper driving mechanism of the windscreen wiper is of a closed structure, 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, 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 cord. 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 process, the cleaning ...

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 changes of the windshield glass surface. During the scraping process, the wiping efficiency is low, and it is not easy to quickly wipe clean. The invention provides a three-blade flexible wall inner support The connecting rod wire wheel type 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
