All-covering type windshield wiper of windshield glass

Abstract

The invention relates to an all-covering type windshield wiper of windshield glass. The all-covering type windshield wiper comprises a motor, transmission mechanisms, torque output ends, main windshield wiper rocker arms, auxiliary windshield wiper rocker arms, a horizontal windshield wiper and windshield wiper blades, wherein an output shaft of the motor is connected with the two transmission mechanisms, and the torque output ends of the two transmission mechanisms are respectively positioned at two sides of the bottom part of front windshield glass; each torque output end is connected with one end of one main windshield wiper rocker arm, the other end of each main windshield wiper rocker arm is respectively hinged to one end of one auxiliary windshield wiper rocker arm, and the other ends of the two auxiliary windshield wiper rocker arms are respectively hinged to two ends of the horizontal windshield wiper; each main windshield wiper rocker arm, each auxiliary windshield wiper rocker arm and the horizontal windshield wiper are respectively connected with one windshield wiper blade; a two-DOF (Degree of Freedom) windshield wiper mechanism is formed by the two main windshield wiper rocker arms, the two auxiliary windshield wiper rocker arms and the horizontal windshield wiper, and an isosceles trapezoid structure is formed by the two-DOF windshield wiper mechanism and the bottom edge of the front windshield glass after the two-DOF windshield wiper mechanism is completely unfolded. According to the all-covering type windshield wiper disclosed by the invention, the view of a driver can be effectively increased, the wiping area can be increased, the swept surface is enabled to have no dead corners, and the all-covering type windshield wiper can be widely applied to the field of various automobile parts.

Description

technical field [0001] The invention relates to an auxiliary part of an automobile, in particular to a windshield wiper fully covered. Background technique [0002] The wiper, also known as the wiper, is an important accessory installed on the windshield. Its function is to sweep away the rain, snow and dust that obstruct the view on the windshield glass to ensure that the driver has good visibility. There are front windshield wipers and rear windshield wipers, which are important parts for safe driving of a car. Wipers can be divided into mechanical, vacuum, pneumatic, hydraulic and electric according to their driving methods. Modern cars generally use electric wipers, which have the advantages of simple structure and convenient control. The electric wiper consists of a motor and a set of actuators including a crank, a transmission rod, a scraper arm and a scraper. The rotation of the motor becomes the swing of the wiper arm through deceleration and the action of the li...

AI Technical Summary

Problems solved by technology

This scheme realizes the sliding rod-sliding sleeve system by means of cross linkage mechanism and crank linkage mechanism, but this structure is complex and does not completely solve the problem of dead angle of the sweeping surface, so it is necessary to seek a mechanical design scheme that can increase the wiping area has a certain practical significance
