## Abstract

A drone delivery system provides to send or to receive the package conveniently and safely without going out of the building by using the platform installed at the vicinity of the window. The drone delivery system includes the drone having a first docking device, a standard box having a second docking device corresponding to the first docking device and a third docking device and a platform having a fourth docking device corresponding to the third docking device.

## Claims

### Claim 1

A drone delivery system comprising:
a platform;
a package box; and
a drone configured to deliver the package box aerially and drop off the package box at the platform, wherein the drone has a first coupling element and a first communication unit,
wherein the package box is configured to form an internal space thereof to enclose a package therein and have a second coupling element and a third coupling element,
wherein the platform, at which the package box is dropped off, is configured to communicate with the drone and have a fourth coupling element and a second communication unit, and
wherein, while the drone is flying to deliver the package box, the first coupling element of the drone and the second coupling element of the package box are coupled to each other,
wherein, during the time when the drone is dropping off the package box at the platform, the drone and the platform exchange information to identify each other through the first communication unit and the second communication unit, the third coupling element of the package box and the fourth coupling element of the platform are coupled to each other, and the first coupling element of the drone and the second coupling element of the package box are decoupled from each other.

### Claim 2 (depends on 1)

The drone delivery system of claim 1, wherein, during the time when the drone is dropping off the package box at the platform, after the drone and the platform exchange the information to identify each other, the third coupling element of the package and the fourth coupling element of the platform are coupled to each other.

### Claim 3 (depends on 1)

The drone delivery system of claim 1, wherein, during the time when the drone is dropping off the package box at the platform, after the third coupling element of the package and the fourth coupling element of the platform are coupled to each other, the first coupling element of the drone and the second coupling element of the package box are decoupled from each other.

### Claim 4 (depends on 1)

The drone delivery system of claim 1, wherein the coupling or the decoupling between the first coupling element of the drone and the second coupling element of the package box takes place at a top side of the package box, wherein the coupling or the decoupling between the third coupling element of the package box and the fourth coupling element of the platform takes place at a bottom side of the package box.
