Electric window regulator

The lifting (closing and opening) of many car door and window glasses has abandoned the manual lifting mode of handle type, and generally switch to the electric lifting mode of button type, that is, the use of electric window regulator.

The electric window regulator used in cars is mostly composed of motor, reducer, guide rope, guide plate, glass mounting bracket, etc. Due to the different materials or manufacturing methods of the guide rope, it is divided into three kinds of electric window regulators: rope wheel type, flexible shaft type and plastic belt type. The first two uses steel wire rope as guide rope, and the latter uses plastic belt as guide rope.

Take the commonly used rope wheel electric window regulator as an example. It is composed of motor, reducer, steel wire rope, guide plate, glass mounting bracket and other parts. During installation, the door and window glass is fixed on the glass mounting bracket, and the glass guide groove is parallel to the steel wire rope guide plate. Turn on the motor, drive the reducer to output power, pull the steel wire rope to move the glass mounting bracket, and force the door and window glass to move up or down in a straight line.

The guide rope of the plastic belt electric window regulator is a plastic belt with holes, which is used to move and position the plastic belt and control the lifting of door and window glass.

The key to the structure of the electric window regulator is the motor and reducer, which are assembled into one. The motor adopts reversible permanent magnet DC motor. There are two groups of coils wound to different magnetic fields in the motor, which can be forward and reverse through the control of the switch, that is, it can control the rise or fall of the door and window glass. The motor is controlled by the double switch button, with three working states of lifting, lowering and closing. When the switch is not operated, it will automatically stop at the “off” position. The control circuit is equipped with a main switch (central control) and a sub switch, which are connected in parallel. The master switch is controlled by the driver to open and close all the door and window glasses, while the passenger controls the opening and closing of each door and window glass respectively for the separate closing on the inner handle of each door, which is very convenient to operate.
