The bearing driving mechanism is fixedly connected with the door leaf through the door carrying frame assembly, the bearing driving mechanism is located above the door leaf, the lower slide way assembly is located below the door leaf and used for supporting opening and closing of the door leaf, and the outer emergency unlocking device is located on the side face of the door leaf and used for controlling the door leaf to be opened from the outside under the emergency situation. The inner emergency unlocking device is located on the side face of the door leaf and used for controlling the door leaf to be opened from the interior under the emergency condition. The built-in closed sliding plug door system is suitable for high-speed freight motor train units and meets the loading and unloading requirements of ultra-large containers, the passing width of the door system can reach 6500 mm, and compared with an outer plug moving door system, the built-in closed sliding plug door system is safer, simple in structure and lower in manufacturing cost and later maintenance cost on the premise that the door system achieves the ultra-large opening degree.
