Description

Automobile windscreen wiper system Technical Field The utility model relates to the technical field of automobile windscreen wiper systems, in particular to an automobile windscreen wiper system. Background The windscreen wiper is an important part in the field of vehicles, and a transmission system drives a windscreen wiper arm to drive a wiper blade to scrape on glass so as to scrape rainwater on the glass. The driving device of the windscreen wiper is usually installed in a front cabin of an automobile, and for a vehicle model with a compact cabin space, the front-rear dimension of a windscreen is long, the horizontal distance between an A column and a front tire is reduced, so that the Y-direction installation space of the driving device is reduced, and the problem that the driving device cannot be installed possibly occurs. Disclosure of utility model In view of the prior art, the utility model aims to provide an automobile windscreen wiper structure which is small and compact in structure and stable in installation. In order to achieve the above purpose, the technical scheme includes that the automobile wiper system comprises a fixing rod used for installing a wiper motor, a wiper arm head is fixedly inserted at the end part of the fixing rod, an installation arm is arranged on the wiper arm head in an extending mode, a screw hole groove is formed in the installation arm and used for being matched with a corresponding screw hole in a frame to fix the wiper arm head, a rod inserting needle is further arranged on one side of the installation arm and used for being matched with a preset positioning hole in the frame to be inserted, and the installation angle of the wiper arm head is positioned. As a further setting of above-mentioned scheme, the wiper arm head articulates there is the swing arm of taking the ball pole, wiper motor main shaft still connects and is equipped with the rocker of taking the ball pole still be equipped with the gangbar between rocker and the swing arm, the gangbar both ends set up respectively with ball pole assorted ball end cover, the bulb portion rotation setting of ball pole is at ball end cover internal activity setting. As a further setting of above-mentioned scheme, the one end of turning shaft is connected wiper motor main shaft, and the other end passes through the bulb pole and articulates on the gangbar, the bulb pole on the swing arm articulates the other end at the gangbar, the fixed turning shaft of wiper motor main shaft drives the swing arm through the gangbar and carries out reciprocating swing when rotating. As a further arrangement of the scheme, a wiper output shaft which is arranged in a rotating way relative to the wiper arm head is arranged in the wiper arm head, and the swing arm and the wiper output shaft are fixedly arranged in the circumferential direction. As a further arrangement of the scheme, the wiper output shaft is also provided with a snap ring groove and a snap ring piece for axially and fixedly mounting the wiper output shaft relative to the wiper arm head.
