Speed regulation control system of windscreen wiper

Abstract

A speed regulation control system of a windscreen wiper comprises a motor, a connecting rod structure, a control module and an induction module; the connecting rod structure converts one-way motion ofthe motor into reciprocating motions of the windscreen wiper on a glass surface, and the induction module is used for inducting discrete signals or continuous signals according to one circle of one-way motions of the motor; the control module is in electric signal connection with the motor and the induction module. And the control module provides a target driving effective voltage corresponding to a signal to the motor for controlling the motor according to the signal fed back by the induction module, so that the motor is driven by the target driving effective voltage corresponding to each group of signals in one-way motions of the motor, and the movement speed of the windscreen wiper is further adjusted. By controlling the driving effective voltage of the motor, the variable-speed motions of the windscreen wiper is controlled, so the windscreen wiper is decelerated near a reverse rotation point, and the windscreen wiper is controlled to run in a certain mode in the middle area, thusincreasing the water wiping speed; it is guaranteed that the operating speed of the windscreen wiper in a whole water wiping period is adjustable, elastic deformation of a wiper blade during high-speed water wiping is reduced, and windscreen wiper reverse rotation noises are reduced.

Description

technical field

[0001] The invention relates to the technical field of wiper speed regulation, in particular to a wiper speed regulation control system. Background technique

[0002] Wipers, also known as wipers, water dials, wipers or windshield wipers, are devices used to wipe off raindrops and dust attached to the windshield of vehicles to improve the visibility of drivers and increase driving safety.

[0003] The wiper is controlled by the high-speed gear and the low-speed gear respectively to perform high-speed wiping and low-speed wiping. Among them, the wiper is driven by the motor through the connecting rod structure. There are two general driving methods:

[0004] One driving method is that the motor runs at a uniform speed in one direction, and then through the connecting rod structure, the one-way movement of one circle is converted into the reciprocating motion of the wiper on the glass surface; It is very good to adjust the reverse speed of the wiper, and it br...
