When one of the door bodies moves up or down, it overlaps with another adjacent door body, does not occupy additional space, and has a wider field of view. At the same time, it avoids the collision between the door body and objects outside the door body, and saves space. When the present invention is applied to a drone hangar, it can facilitate the smooth extension of the apron into the hangar, and avoids hindering the docking and take-off of the drone.

[0025] Further, a single group of the driving mechanism includes a driver and a driving rod, wherein the driver is connected to the driving rod in a transmission manner; the driving rod is connected to the door body in a transmission manner, and the door body is connected to the guide mechanism in a sliding manner. In this embodiment, the driver adopts a motor 305, and the driving rod adopts a screw rod. Synchronous wheels 307 are respectively arranged on the output shaft of the motor 305 and the screw rod, and the synchronous wheels 307 on the motor 305 are connected to the synchronous wheels 307 on the screw rod through a belt 306, that is, the output shaft of the motor 305 rotates to drive the synchronous wheel 307 connected thereto to rotate, thereby driving the belt 306 to rotate, and then driving the synchronous wheel 307 connected to the screw rod to rotate, so as to drive the screw rod to rotate, and finally, the screw rod drives the door body to move up and down, specifically, a screw rod nut is arranged on the screw rod, and the door body is connected to the screw rod nut, and the screw rod rotates forward or reversely, so that the screw rod nut moves up or down along the screw rod, so as to realize the upward or downward movement of the door body.

[0026] Preferably, a connecting piece is provided on the longitudinal side of the door body, and the door body is connected to the drive rod and the guide mechanism through the connecting piece. In this embodiment, the door body is connected to the screw rod and the guide mechanism through the connecting piece.
