The motor 2 is used to drive a linkage mechanism 3 to work. A linkage mechanism 3 is installed on one side of the motor 2. A plurality of sliding seats 4 are installed at one end of the linkage mechanism 3. The sliding seats 4 can move along a slide rail 5, thereby adjusting the included angle between the movable frames 306. A slide rail 5 is arranged outside the sliding seats 4. The slide rail 5 can guide and support the sliding seats 4. Rolling mechanisms 6 are arranged at both the top and bottom ends of the sliding seats 4. The rolling mechanism 6 includes an empty groove 601 opened on the sliding seat 4. The empty groove 601 is used to carry a roller 603. Main shafts 602 are symmetrically installed in the empty groove 601. The main shafts 602 can support the roller 603. The roller 603 is rotatably connected to the outside of the main shaft 602. The roller 603 can abut against the inner wall of the slide rail 5 to reduce the friction when the sliding seat 4 moves. And the outside of the roller 603 is located outside the sliding seat 4, and the outside of the roller 603 abuts against the inner wall of the slide rail 5.

[0022] As Figures 1 - 2 shown, the linkage mechanism 3 includes a driving wheel 301, a main frame 302, a tooth groove 303, a support shaft 304, a connecting shaft 305 and a movable frame 306, which facilitates driving the window to rise and fall through the linkage mechanism 3.

[0023] As Figures 1 - 2 shown, the driving wheel 301 is connected to the output end of the motor 2, and the driving wheel 301 is connected to the main frame 302 through the tooth groove 303, which can enable the motor 2 to drive the driving wheel 301 to rotate, and the driving wheel 301 drives the main frame 302 to rotate through the tooth groove 303.

[0024] As Figures 1 - 2 shown, the main frame 302 is rotatably connected to the mounting base 1 through the support shaft 304, which facilitates supporting the main frame 302 through the support shaft 304, and the main frame 302 can rotate along the support shaft 304.

[0025] As Figures 1 - 2 shown, the connecting shaft 305 is located on one side of the main frame 302, and the movable frame 306 is rotatably connected to the main frame 302 through the connecting shaft 305, which facilitates the main frame 302 to drive the connecting shaft 305 to rotate, and the connecting shaft 305 can drive the movable frame 306 to rotate during the rotation process.

[0026] As Figures 1 - 2 shown, the terminal of the movable frame 306 is rotatably connected to the sliding seat 4, which can drive the sliding seat 4 to move horizontally along the slide rail 5 during the rotation process of the movable frame 306.

The driving wheel 301 drives the main frame 302 to rotate along the support shaft 304 through the tooth groove 303. And the main frame 302 can drive the movable frame 306 to rotate through the connecting shaft 305. The movable frame 306 drives the sliding seat 4 to move horizontally inside the sliding rail 5 during the rotation process, thereby driving the sliding rail 5 located above to rise and fall inside the car door. And the window 8 is fixed at the sliding rail 5 above through the support seat 7, thus realizing the rising and falling of the window 8. During the movement of the sliding seat 4 along the sliding rail 5, the outer side of the roller 603 can abut against the inner wall of the sliding rail 5 and rotate along the main shaft 602 under the influence of friction, thereby preventing the sliding seat 4 from rubbing against the sliding rail 5 during the movement and ensuring the smoothness of the sliding, thereby improving the stability of the window opening and closing.
