Master switch for window regulator introduce

The key to the structure of an electric window regulator is the electric motor and reducer, which are assembled into one. The electric motor adopts a reversible permanent magnet DC motor, which has two sets of magnetic field coils wound in different directions inside the motor. Through the control of the switch, it can perform forward and reverse rotation, which means it can control the rise or fall of the door and window glass. The electric motor is controlled by a double switch button and has three working states: up, down, and off, When the switch is not operated, it automatically stops at the "off" position. The control circuit is equipped with a main switch (central control) and a sub switch, and the two lines are connected in parallel with the electric window regulator. Many car door and window glass lifting (closing and opening) have abandoned the manual lifting method of the handle type and generally switch to the button type electric lifting method, Electric window lifters are commonly used in cars. Most electric window lifters used in cars are composed of electric motors, reducers, guide ropes, guide plates, glass mounting brackets, etc. Due to the different materials or manufacturing processes of the guide ropes, they can be divided into three types: rope wheel type, flexible shaft type, and plastic belt type. The first two types use steel wire rope as the guide rope, and the last type uses plastic belt as the guide rope. Taking the commonly used rope wheel type electric window lifter as an example, It is composed of components such as an electric motor, reducer, steel wire rope, guide plate, and glass mounting bracket. During installation, the door and window glass are fixed on the glass mounting bracket, and the glass guide groove is parallel to the steel wire rope guide plate. When the electric motor is turned on, the reducer is driven by the electric motor to output power, and the steel wire rope moves the glass mounting bracket, forcing the door and window glass to move up or down in a straight line. The guide rope of the plastic belt type electric glass lifter is made of plastic tape, The belt has holes for moving and positioning plastic strips, controlling the lifting of door and window glass. The key to the structure of the electric window regulator is the electric motor and reducer, which are assembled into one. The electric motor adopts a reversible permanent magnet DC motor, and there are two sets of coils winding towards different magnetic fields inside the motor. Through the control of the switch, forward and reverse rotation can be achieved, That is to say, it is possible to control the rise or fall of door and window glass. The electric motor is controlled by a dual switch button, with three working states: up, down, and off. When the switch is not operated, it automatically stops in the "off" position. The control circuit is equipped with a main switch (central control) and a sub switch, both of which are connected in parallel. The main switch is controlled by the driver to open and close all door and window glass, and the separate opening and closing of each door handle is controlled by the passenger to open and close each door and window glass, The operation is very convenient)

The replacement method for the window regulator switch is

The replacement method for the window regulator switch is as follows: 1. Open the door on the side where the switch needs to be replaced, and find the gap at the joint between the decorative panel and the door panel; 2. Insert the tool into the gap and lift the decorative panel, then remove it along the gap; 3. Pick up the decorative panel and unplug the plug of the lifting switch; 4. Turn the decorative panel upside down, unscrew the small screw that fixes the switch, and remove the lifting switch; 5. Replace with a new lifting switch, tighten the screws and plug in the plug; 6. Test the lifting and lowering function, and after confirming that the switch is working properly, simply install the decorative panel back. The reason for the glass lifting and lowering to become stuck is: 1. The rubber of the window glass is aging and dust is accumulating; 2. Excessive dirt or foreign objects in the car glass guide groove; 3. Malfunction of glass lifting components

Ripher introduce

From the feedback from Huapu's car enthusiasts forum, it can be seen that major problems are not common, and small problems are constantly a common problem. Here, I just want to say that there are also quite a few million BMW problems, and everything has problems that are not perfect. The 50000 yuan sedan, at such a low price point, is quite attractive. Based on the information I have learned, let me tell you about the Huapu Langfeng: the predecessor of the current sea area is the Langfeng, Later it was changed to a sea area, and now many of the sea areas on the forum are old models of the Langfeng. This car was once popular, but unfortunately it did not continue to develop. Even the Huapu brand was not retained, and now it has been changed to the UK, a joint venture brand. Currently, the Huapu Langfeng has been discontinued, and because it is an older model, many configurations are not as good as the current car. Therefore, it is recommended that those who purchase a second-hand Huapu Langfeng should change to a different model
