Novel automobile windscreen wiper system

Abstract

The invention relates to a novel automobile windscreen wiper system which comprises windscreen wipers, a windscreen wiper motor, an electromagnetic air sucking pump, a water tank, a high-pressure water pump, a heat exchanger, a floating ball check valve and a cleaning agent tank. The windscreen wipers are installed at two ends of the windscreen wiper motor, the electromagnetic air sucking pump and the cleaning agent tank are connected with the windscreen wipers through pipes, the water tank, the high-pressure water pump, the heat exchanger, the floating ball check valve and the cleaning agent tank are sequentially connected through a pipe, and the heat exchanger is connected with an engine exhausting pipe through a pipe. The cleaning area of each windscreen wiper is increased through a centrifugal force produced by the windscreen wiper during swing, the cleaning areas of the windscreen wipers basically cover a whole windscreen, meanwhile the windscreen wipers can be automatically lifted away from the windscreen after flameout of an automobile, the phenomenon that the windscreen wipers are frozen on the windscreen in winter is avoided, and the service life of the windscreen wipers is prolonged.

Description

technical field [0001] The invention belongs to the technical field of vehicle equipment, and in particular relates to a novel vehicle wiper system. Background technique [0002] The scientific name of the wiper is a wiper, which refers to a piece structure installed in front of the windshield. It is composed of a motor, a reducer, a four-bar linkage, a wiper arm spindle, and a wiper blade assembly. Rain, snow and dust on the windshield obstructing vision. [0003] The power source of the wiper comes from the electric motor, which is the core of the entire wiper system. The quality requirements for wiper motors are quite high. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the mechanical part of the worm gear. The effect of the worm and gear mechanism is to reduce the speed and increase the twist. Its output shaft drives the four-bar linkage, and the continuous rotational motion is changed into a lef...

AI Technical Summary

Problems solved by technology

The stretching amount of the patented telescopic wiper rod has a certain limit, and the enlarged cleaning area is limited. At the same time, the patent cannot lift the wiper away from the windshield of the car. The temperature drops in winter, and the wiper is easy to freeze on the windshield of the car.
