Description

Technical Field

[0001] This utility model relates to the field of automotive window regulator technology, specifically a fork-arm type automotive window regulator. Background Technology

[0002] In the automotive manufacturing industry, power windows are a key component of the door system, and their performance directly affects the smoothness of window operation, passenger comfort, and the overall quality of the vehicle. Traditional automotive power windows have some limitations in design and use, such as complex structure, inconvenient installation, movement interference, and limited travel. These problems not only increase manufacturing and maintenance costs but may also affect the reliability and durability of the power windows.

[0003] Existing automotive window regulators often employ complex linkage mechanisms or wire rope structures. These structures frequently require significant modifications to the car door during installation, increasing installation difficulty and time costs. Furthermore, traditional regulators often suffer from unstable operation and high noise levels due to friction and interference between components during the lifting process. Additionally, due to structural limitations, traditional regulators have relatively short strokes, failing to meet the needs of some special car models or window designs.

[0004] Therefore, we propose a fork-arm type automotive window regulator to solve the above problems. Utility Model Content

The technical solution adopted includes an active arm assembly, a driven arm, a short cross arm, a long slide rail, a short slide rail, and a motor mounting plate. The long slide rail is installed on the side wall of the car door. The driven arm and the short cross arm are rotatably installed with the middle of the active arm assembly through a connecting component. The active arm assembly and the driven arm are installed with the long slide rail through pulleys slidably installed inside the long slide rail. The other end of the active arm assembly is provided with a toothed plate, and the center of the toothed plate is installed with the active arm assembly through a mounting component. The motor mounting plate is installed on the inner side wall of the car door panel. A motor is installed on the motor mounting plate through a pinion gear meshing with the toothed plate. The short slide rail is installed on the inner side wall of the car door panel. The short cross arm is installed with the short slide rail through rollers slidably installed inside the short slide rail. Glass brackets that are assembled and installed with the glass are provided at both ends of the long slide rail.

[0006] As a preferred embodiment of the present invention, the long slide groove includes an upper slide groove, a lower slide groove, and a bent portion for connecting the upper slide groove and the lower slide groove.
