Front door glass lifter assembly action.
The main function of the front door glass lifter assembly is to allow passengers in the car to easily control the opening and closing of the window, and has anti-pinch function and one-click window lowering function to ensure passenger safety and comfort.
The front door glass lifter assembly is an important part of the car door and window system, which is composed of the control mechanism (rocker arm or electric control system), the transmission mechanism (gear, tooth plate or rack, gear flexible shaft meshing mechanism), the glass lifting mechanism (lifting arm, movement bracket), the glass support mechanism (glass bracket) and the stop spring, balance spring and other parts. These components work together to achieve the smooth lifting of the window glass, ensure the smoothness of the door glass lifting, so that the door and window can be opened and closed at any time. In addition, when the lifter is not working, the glass can stay in any position, providing great convenience and flexibility.
In addition to the basic lifting function, the front door glass lifter assembly also has some special features such as emergency closing and anti-pinch functions. The emergency shutdown function can be used in the event of an external attack or condensation of the side window glass to ensure the safety of passengers. Anti-clip function is one of the important features of the window lifter, when the window rises, if there is a human body part or object in the rising area, it will immediately reverse (drop) a certain distance, and then stop to prevent passengers from being caught. This function can effectively protect the safety of passengers and avoid injuries caused by objects or people caught in the window. In addition, the window lifter of modern cars also has a one-button window lowering function, only need to press the control switch on the door to the "one-button down" gear, you can realize the automatic window lowering, convenient for passengers to quickly lower the window.
In short, the role of the front door glass lifter assembly is not only to control the lift of the window, but more importantly, to enhance the passenger experience and safety through its additional safety and convenience features.
What are the common failures of glass lifters?
Common faults of the glass regulator include: abnormal noise of the glass when the car is jolted; The glass makes abnormal sound during the lifting process; Glass lifting difficulty; When the glass is halfway up, it automatically descends. Some glitches can be fixed by hand.
1. When the car is jolted, the glass has abnormal noise.
Cause: Screws or clasp loose; There are foreign objects in the interior of the door; There is a gap between the glass seal and the glass seal. To solve this small fault, just clean the foreign matter in time, fix the glass, fix the screw or replace the inner batten.
2. The glass makes an abnormal sound during lifting.
Reason analysis: First, the guide rail of the glass regulator is abnormal, just clean the guide rail and apply some lubricating oil; If it still does not improve, it should be the glass lifting part is faulty, and the glass elevator assembly needs to be replaced. It is recommended to find a regular repair shop or 4S point for maintenance.
Third, the glass lifting is difficult
Reason: a glass tape aging deformation, resulting in lifting glass resistance. It is necessary to replace the seal with a new one. If it is not serious, apply talcum powder lubrication to solve the temporary problem. First, the glass lifting guide rail is too dirty, there are foreign bodies. When waiting at a red light, people often push business cards through the Windows, resulting in foreign objects on the railing. Need to wash and remove foreign objects; The other is a motor failure or low battery power, and the motor needs to be charged or replaced.
Fourth, the glass will automatically fall after rising halfway.
Cause: It could be a seal or a glass regulator. Generally equipped with window glass anti-pinch function of the car will encounter these problems. If this problem occurs in the car within three years, most of it should be the fault of the elevator.
