Three-blade flexible wall round hole supporting wiper linkage flexible shaft type wiper

Abstract

A three-scraping-piece flexible wall round hole internal-supported wiper connecting rod flexible shaft 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 wiper drive shaft and a driving wiper drive shaft, the driven wiper drive shaft and the driving wiper drive shaft are respectively provided with a driven gear and a driving gear, and the driven gear and the driving gear are connected through a flexible shaft and transfer torque. A closed connecting rod rocker arm driving mechanism is arranged on the driving gear. The wiper driving mechanism of the windscreen wiper is of a closed structure, is low in noise during working and is especially suitable for a complicated external environment structure and remote transmission, 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 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, which belongs to the field of automobile wipers, in particular to a wiper driven by a flexible shaft. 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 is not easy to scrape quickly, it i...

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 scraper 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 scrape clean. The invention provides a three-blade flexible wall inner support Wiper linkage flexible shaft type 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
