[0002] A window lifter is a device used to lift and lower window glass. The window lifter motor mechanism is the core part that controls the lifting and lowering of car windows. After receiving the control signal, this mechanism will drive the motor to work, and convert the motor's rotational motion into the lifting and lowering motion of the window through the reducer and the connecting rod, thereby realizing the opening and closing of the window. The motor is the key part of the window lifter motor mechanism and is responsible for providing power to realize automatic lifting and lowering of the window. The existing window lifter motor mechanism is usually directly embedded in the card slot inside the door, which is easily affected by external forces during operation and is prone to displacement or slippage, resulting in reduced stability.

With the mutual cooperation of the first anti-detachment component, the second anti-detachment component and the third anti-detachment component, the lifting component can be fixed and limited in multiple directions, so that it is not easy to shift or slip during the process of controlling the lifting of the vehicle window glass, and the anti-detachment effect is better.

[0006] Preferably, the lifting assembly includes a driving gear, a driven arc gear, a driving motor, a lifting rod and a first slider. The left end of the driving gear is meshingly connected with a driven arc gear for controlling the lifting of the lifting rod. The driving motor drives the driven arc gear to rotate synchronously by driving the driving gear. The rear end of the driven arc gear is rotationally connected with a lifting rod for controlling the first slider to slide along the first slide groove. The lifting rod is fixedly connected to the first slider away from the driven arc gear. The first slider is engaged and slidably connected with the first slide groove.

By fixing the third mounting plate through the third mounting holes, its stability can be increased, thereby achieving a better anti-slip effect.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional window lifter motor mechanism, which is usually directly embedded in the card slot inside the door, it is easy to be affected by external forces during operation and is easy to deviate or slip, resulting in reduced stability. By setting the first anti-slip component and the second anti-slip component, the lifting component can be fixed in both directions, so that the lifting component can be firmly fixed inside the door, making it difficult to slip. By setting the first anti-slip component, the lifting component can be fixed from the front end, and the driven arc gear can be supported by setting the connecting column to increase its stability. By setting the reinforcement block, the drive motor can be symmetrically supported, thereby increasing the stability of the drive motor. A first clamping strip is provided at one end of the lifting assembly to be engaged with the vehicle door, and the first mounting plate can be installed and fixed on the vehicle door by opening a first mounting hole on the first mounting plate so that it is fixed, thereby making the first anti-detachment assembly more stable, and the rear end of the lifting assembly can be fixed by providing a second anti-detachment assembly, and the driving gear can be supported by providing a second mounting plate, and the lower end of the second mounting plate is installed and fixed on the vehicle door through the second mounting hole, so that the second mounting plate can stably support the driving gear, and the lifting assembly is bidirectionally supported and fixed by the first anti-detachment assembly and the second anti-detachment assembly, thereby making it difficult for the lifting assembly to fall off or deviate.

[0014] 2. The window glass can be limited by arranging the third anti-slip assembly to prevent it from deviating or slipping during the lifting process. The two sets of third mounting plates can be symmetrically arranged to be engaged with the block at the rear end of the mounting strip, and the block can be limited by providing a second slide groove to be engaged with the block so that the block always moves up and down along the second slide groove, thereby driving the window glass to be lifted vertically. The lifting assembly can be controlled to automatically lift the window glass, and the driving motor can drive the active gear to rotate so that the active gear drives the driven arc gear to rotate, and then the driven arc gear drives the lifting rod to rotate synchronously to drive the block at the rear end of the mounting strip to slide up and down along the second slide groove to drive the window glass to lift and lower, and the first slider away from one end of the driven arc gear of the lifting rod moves left and right along the first slide groove to perform linkage. Under the synchronous limiting action of the first slide groove and the second slide groove, the block and the first slider can slide along the predetermined track and are not easy to slip.
