The invention provides an opening and closing mechanism and a rail vehicle. The opening and closing mechanism comprises a supporting base body, a rotating arm, a first rotating piece, a first transmission piece and a motion locking mechanism, wherein the rotating arm is rotationally connected with the supporting base body; the first rotating piece and the rotating arm are arranged in a spaced manner; the first rotating piece is rotationally connected with the supporting base body; the first transmission piece is rotationally connected with the rotating arm; the first transmission piece is rotationally connected with the first rotating piece; the motion locking mechanism is arranged on the supporting base body; the motion locking mechanism is connected with the first rotating piece in a matched manner; when the motion locking mechanism moves, the first rotating piece, the first transmission piece and the rotating arm move in a four-connecting-rod motion manner; and the rail vehicle comprises the opening and closing mechanism. According to the opening and closing mechanism and the rail vehicle, the phenomenon that an opening and closing mechanism and a motion mechanism of the openingand closing mechanism interfere with each other is well avoided.
