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 lead to the burnout of the wiper motor. The present invention provides A flexible shaft type wiper drive mechanism, which is a completely closed structure with low noise and is not affected by the external environment

Abstract

A flexible shaft type windscreen wiper driving mechanism comprises a wiper motor and a wiper drive shaft and is characterized in that the 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 forward and reverse rotating gear intermittent drive 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, is especially suitable for a complicated external environment structure and remote transmission, can adapt to vehicle of different models 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, and the interior comfort of a vehicle in running is improved.

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 drive mechanism 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. Caused the wiper motor to burn out. Contents of the invention [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 lead to the burnout of the wiper motor. The present invention provides The utility model relates to a flexible shaft wiper driving mechanism, which is a completely closed structure ...
