Drone takeoff and landing system

1. A drone takeoff-and-landing system, comprising: a drone including a through-hole and a landing stand including a landing pad and an extension member provided on one surface of the landing pad and configured to pass through the through-hole,

wherein

the through-hole is formed on a side surface of a main body of the drone such that one surface of the through-hole is opened in a direction towards an outside of the main body,

the extension member of the landing stand is configured to move vertically from the landing pad and configured to move selectively upwards or downwards when the drone takes off or lands, and

when the extension member passes through the through-hole of the drone, an eddy current is generated between the through-hole and the extension member and magnetic braking or wireless charging occurs in the drone.

2. The drone takeoff-and-landing system of claim 1 , wherein the through-hole is one of a plurality of through-holes and wherein the extension member is one of a plurality of extension members.

3. The drone takeoff-and-landing system of claim 1 , wherein a magnetic body or an electromagnet is disposed in the through-hole, wherein a nonferrous conductor is disposed in the extension member, and wherein the eddy current is generated between the magnetic body or the electromagnet and the nonferrous conductor.

4. The drone takeoff-and-landing system of claim 1 , wherein a nonferrous conductor is disposed in the through-hole, wherein a magnetic body or an electromagnet is disposed in the extension member, and wherein the eddy current is generated between the magnetic body or the electromagnet, and the nonferrous conductor.

5. The drone takeoff-and-landing system of claim 1 , wherein a first electromagnet is disposed in the through-hole, wherein a second electromagnet is disposed in the extension member, and wherein a magnetic field of the first electromagnet and the second electromagnet is controlled to control a takeoff or landing speed of the drone or wirelessly charge the drone.

6. A drone takeoff-and-landing system comprising:

a landing module attachable to or detachable from a drone and including a through-hole and

a landing stand including a landing pad and an extension member provided on one surface of the landing pad and configured to pass through the through-hole,

wherein, in a case in which the landing module is attached to the drone, an eddy current or a magnetic field is generated between the through-hole and the extension member when the extension member passes through the through-hole to control a speed of the drone or wirelessly charge the drone,

wherein the landing module includes: a plurality of pass-through members, each of which includes a through-hole, and a connection member configured to connect the pass-through members and to be attachable to and detachable from the drone, and

wherein the connection member is formed of an elastic material such that a length thereof is adjustable or a length of the connection member is adjustable through screw tightening.

7. The drone takeoff-and-landing system of claim 6 , wherein a magnetic body or an electromagnet is disposed in one of the through-hole and the extension member and a nonferrous conductor is disposed in the other, wherein the eddy current is generated between the magnetic body or the electromagnet and the nonferrous conductor, and wherein the magnetic braking or wireless charging occurs in the drone.

8. The drone takeoff-and-landing system of claim 6 , wherein a first electromagnet is disposed in the through-hole, wherein a second electromagnet is disposed in the extension member, and wherein a magnetic field of the first electromagnet and the second electromagnet is controlled to control a takeoff or landing speed of the drone or to wirelessly charge the drone.
