Speed regulation control system of wiper blade

Abstract

The invention discloses a speed regulation control system of a wiper blade. The speed regulation control system includes a motor, a connecting rod structure, a mould-making module and an induction module, wherein unidirectional movement of the motor is converted into reciprocating movement of the wiper blade on a glass surface through the connecting rod structure, and the induction module is usedfor inducing discrete signals or continuous signals according to one round of unidirectional movement of the motor; a control module is electrically connected with the motor and the induction module and provides target-drive effective voltages corresponding the signals and controlling the motor for the motor according to the feedback signals of the induction module, thus the motor is driven through the target-drive effective voltages corresponding to all the groups of the signals in the unidirectional movement of the motor, and thus the movement speed of the wiper blade is regulated. The driveeffective voltages of the motor are controlled, thus the water-wiper speed is improved, it is guaranteed that the operation speed of the wiper blade can be regulated in the whole water-wiper cycle, elastic deformation of doctor blades in high-speed water-wiper is reduced, and inversion noise of the wiper blade is 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...
