[0029] Please refer to Figure 1 and Figure 2 , the present application provides a sliding door driving mechanism 100, which comprises a hinge 1, a pull wire set 2 and a guide rail 3, wherein the hinge 1 comprises a pull wire bracket 11; the pull wire set 2 comprises a pull wire 21, and the pull wire 21 is connected with the pull wire bracket 11; the guide rail 3 cooperates with the hinge 1 to realize the sliding of the hinge 1 relative to the guide rail 3, and the front end of the guide rail 3 has an opening 35 through which the pull wire 21 passes. Specifically, the pull wire 21 in the pull wire set 2 is connected with the pull wire bracket 11 in the hinge 1, and when the pull wire 21 moves, it drives the pull wire bracket 11 to move, at this time the hinge 1 moves with the pull wire bracket 11, and the guide rail 3 provides a track for the movement of the hinge 1, so that the hinge 1 moves within the length range of the guide rail 3. At the same time, in the sliding door driving mechanism 100 of the present application, the pull wire bracket 11 is located on the side of the hinge 1 close to the side wall of the guide rail 3, and the opening 35 is provided at the front end of the guide rail 3 for the pull wire 21 to pass through, thereby reducing the volume of the hinge 1 and the guide rail 3 at the C pillar, thereby avoiding the problem of interior bulging at the C pillar and improving the aesthetic appearance.

[0030] Please refer to Figure 2 and Figure 3 , the guide rail 3 comprises a first track 31 and a second track 32 connected with each other, the first track 31 and the second track 32 have the same height, the first track 31 is bent towards the inside of the vehicle body relative to the second track 32, and the guide rail 3 is integrally formed. Specifically, the guide rail 3 is installed at the position of the rear hatch of the MPV vehicle, the first track 31 and the second track 32 in the guide rail 3 have the same height, so that the installation mode of the guide rail 3 is simple and convenient for installation and use. At the same time, the first track 31 is bent towards the inside of the vehicle body relative to the second track 32, which is convenient for the connection of the guide rail 3 and the hinge 1, and is also convenient for the sliding of the sliding door relative to the rear hatch. At the same time, the included angle between the first track 31 and the second track 32 is greater than 90°, so that the guide rail 3 transitions smoothly, which is beneficial to the smooth sliding of the sliding door.

[0031] Please continue to refer to Figure 2The rear end of the opening 35 has an inclined angle. Specifically, the pull wire 21 mainly contacts the rear end of the opening 35 when passing through the opening 35. By processing the rear end of the opening 35 with an inclined angle, the friction between the rear end of the opening 35 and the pull wire 21 is reduced, so that the pull wire 21 will not be damaged when moving forward and backward. Of course, a passivation layer or wear-resistant material can also be added to the rear end of the opening 35 to improve the overall service life.

[0032] Please continue to refer to Figure 1 The pull wire set 2 further comprises a first fixing member (not shown in the figure), which is located on the back of the guide rail 3 and close to the front end of the guide rail 3. One end of the pull wire 21 is connected to the pull wire bracket 11 through the first fixing member and the opening. Specifically, the first fixing member is located on the vehicle body and on the inner side of the vehicle body, and the guide rail 3 is located on the outer side of the vehicle body. The first fixing member is located close to the front end of the guide rail 3, which facilitates shortening the distance between the pull wire bracket 11 and the first fixing member. The pull wire 21 fixed by the pull wire bracket 11 passes through the first fixing member through the opening. By controlling the length of the pull wire 21 between the first fixing member and the pull wire bracket 11, the opening and closing of the sliding door can be controlled.

[0033] Please continue to refer to Figure 1 The pull wire set 2 further comprises a second fixing member 22 and a driving motor 23. The second fixing member 22 is located on the back of the guide rail 3 and close to the rear end of the guide rail 3. The other end of the pull wire 21 is connected to the pull wire bracket 11 through the second fixing member 22.
