DELIVERY DEVICE, CHARGING SYSTEM AND METHOD OF OPERATING CHARGING SYSTEM

摘要

A delivery device comprises an unmanned airplane and a delivery box. The unmanned airplane includes a flight power device, a plurality of propellers, a connecting part, and connecting legs. The flight power device provides power. The plurality of propellers are radially arranged along a first direction from the flight power device. The plurality of propellers are operated with power. The connecting part is connected to the flight power device along a second direction which is opposite to the first direction. The connecting part is square-shaped. The connecting legs are connected to the flight power device along the second direction. The delivery box has a first surface and first to fourth sides. The first to fourth sides connect each edge of the square-shaped connecting part and each edge of the square-shaped first surface. The connecting legs are connected to hinges coupled to two opposing edges among four edges of the first surface. The first to fourth sides are separated from the connecting part and contact with a contact surface contacting with the first surface when charging. The first to fourth sides receive power via a plurality of coils included in the first to fourth sides based on an inductive charge system and supply the power to the unmanned airplane. The delivery device according to an embodiment of the present invention can improve efficiency of a delivery service by wirelessly receiving power using the sides of the delivery box and supplying to the unmanned airplane.
