Background

In the related art, a door drive of a sliding plug door is arranged above a vehicle door, and the bearing and opening and closing movement of a door leaf of the sliding plug door are realized by a bearing mechanism and a driving structure in the upper door drive. Usually, a door carrying frame is arranged on the upper part of the door leaf and connected with the door drive, a plug roller is arranged on the door carrying frame, and the plug roller is matched with an upper guide rail in the door drive to restrict the motion track of the door leaf. Since the fixed connection point of the door leaf is at the upper part, the gravity of the door leaf can provide pressing force between the door leaf and the vehicle body as shown in fig. 4a, but when the door drive is arranged below the door leaf, the gravity of the door leaf makes the door leaf tend to turn outwards as shown in fig. 4 b.

For a sliding plug door with a door drive located below the door leaf, the door leaf tends to turn outwards under the action of gravity after the door drive is placed below the door leaf, as shown in fig. 4 b. The trend causes the gap between the upper part of the door leaf and the vehicle body to be difficult to compress, a gap exists, and the sealing performance is poor. Thus, the upper part of the door leaves lacks a mechanism to provide sufficient pulling force to ensure sealing between the door panel and the vehicle body.
