Specifically, this application is through addding this slide rail 1, slider assembly 10, link mechanism 20 and drive assembly 6, when side door 200 on the vehicle is in closed condition, the area that forms between link mechanism 20 and the slide rail 1 is minimum, at this moment, link mechanism 20 is shortest to the distance between the slide rail 1, when the side door 200 on the vehicle needs to be opened, this drive assembly 6 begins to move, through the motion of this drive assembly 6, make slider assembly 10 move on this slide rail 1, through slider assembly 10's motion, drive this link mechanism 20 and move towards the direction of keeping away from this slide rail 1. It can be seen that this application only needs to add a slide rail 1, can realize opening and closing of side door 200, need not to add 3 slide rails among the prior art to the quantity of slide rail has been saved widely, simultaneously, has also avoided effectively using three tracks so that to the great and comparatively complicated condition of structure of restriction to the motorcycle type, the door motion that slides of this application no longer is subject to the figurative restriction of whole car, only need arrange a slide rail and can realize the switching of side door 200, the application scope of door that slides has been improved greatly.
