The invention relates to an unmanned aerial vehicle hangar, and belongs to the technical field of landing assistance of unmanned aerial vehicle. The unmanned aerial vehicle hangar comprises a controller, a parking apron and an automatic charging device, wherein the automatic charging device is controlled by the controller. The controller comprises a memory and a processor; the automatic charging device comprises a pair of clamping and pressing assemblies; each clamping and pressing assembly comprises a clamping claw, an actuator and a charging electrode, wherein the clamping claw is used for clamping and pressing a landing gear transverse rod of the unmanned aerial vehicle; the clamping claw is driven by the actuator to move in the position between clamping and pressing charging position and releasing position, and the charging electrode is fixedly arranged on the charging claw. By arranging the clamping claw and fixedly arranging the charging electrode on the clamping claw, the unmanned aerial vehicle under the charging state is fixed to the parking apron, so that continuity and stability of the charging process are guaranteed.
