Double blade flexible wall wiper linkage hydraulic swing wiper

Abstract

The invention provides a double-scraper flexible-wall and hydraulic swinging wiper brush connecting rod type windscreen wiper. The double-scraper flexible-wall and hydraulic swinging connecting rod type windscreen wiper comprises a wiper motor, a wiper brush driving motor and a wiper brush. The double-scraper flexible-wall and hydraulic swinging wiper brush connecting rod type windscreen wiper is characterized in that two gear rack swinging oil cylinders are communicated through a hydraulic oil pipe to transmit torque; a connecting rod rocker arm driving mechanism is arranged on a driving gear rack swinging oil cylinder. The double-scraper flexible-wall and hydraulic swinging wiper brush connecting rod type windscreen wiper has the beneficial effects that the wiper brush driving mechanism is hydraulically transmitted through a flexible pipeline; the mounting is greatly avoided structural limitation; in addition, the a completely closed structure is provided; the working generates little noise; the complex external environment and long-distance transmission particularly apply, and moreover, outside influence is prevented, so that the shortage that the wiper motor is burnt through an external barrier can be avoided; the noise in a vehicle can be effectively reduced; the internal comfort of the vehicle in running can be improved; rubber strips of the wiper are supported through flexible walls and can be clung to a windscreen; the scraping efficiency of the double-scraper structure is doubled that of the general single-scraper structure.

Description

technical field [0001] The invention relates to a windshield wiper, which belongs to the field of automobile windshield wipers, in particular to a windshield wiper driven by a 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 eff...

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 windshield glass surface, and the wiping efficiency is low during the scraping process, and it is not easy to quickly wipe clean. The invention provides a hydraulic swing wiper with double blade flexible wall wiper linkage , it 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
