Description

Cargo Loading Port For Cargo Transporting Drone}

The present invention relates to a cargo unloading port for a cargo transport drone, and more particularly, to a cargo unloading port for a cargo transport drone including a configuration capable of inducing safe landing of the drone and safe unloading of cargo.

A drone is an unmanned aerial vehicle capable of remote control and automatic flight, and basically obtains lift and propulsion by rotating at least one rotor. In general, drones are classified into a quadropter with four rotors, a hexacopter with six, and an octocopter with eight, and are collectively referred to as a multicopter.

A drone has a main body, a plurality of support arms extending radially from the main body, and a rotor installed at the end of the support arm. These drones are applied to various industrial fields by mounting various additional devices such as photographing equipment, control equipment, first aid equipment, and mounting equipment under the main body.

These drones are expected to be widely used for courier services that deliver goods to their destinations.

In general, a delivery drone is equipped with a wire lifting device in which a predetermined gripper is mounted under the main body or a hook-shaped locking mechanism is hung at the bottom to support the unloading operation of loading or unloading the package.

However, the conventional delivery drone using a wire lifting device is inconvenient because a person must manually separate the package from the wire locking device when putting the package down.

In addition, conventional delivery drones require countermeasures because the wires are shaken by the wind of the rotor during the unloading work of loading or unloading packages, so that the work may not be performed smoothly or a safety accident may occur. In this way, the problem of the wire shaking by the wind of the rotor occurs particularly severely at a location close to the drone.

In order to solve this problem, as shown in FIG. 1, the lifting body 100 and the disposable locking body 200 of a specific structure are also used, but this is also affected by the environment during the unloading operation to ensure a stable operation. No, it cannot solve the security problem of unloaded cargo.

Therefore, there is a need for a technology capable of solving the problems according to the prior art mentioned above.
