Abstract

Disclosed is a drone station which allows the center of resonance of a drone to be always accurately aligned regardless of the initial landing position of the drone. The disclosed drone station includes a landing guidance instrument and a wireless charging instrument which is formed on the landing guidance instrument and wirelessly transmits the power to a drone positioned thereon, the landing guidance instrument having an inclined surface which moves the landed drone onto the top of the wireless charging instrument.

First claim

The invention claimed is:

1. A drone station comprising:
a wireless charging instrument formed on a landing guidance instrument, and for wirelessly transmitting a power to a drone positioned thereon;
the landing guidance instrument having an inclined surface moving a landed drone to the top of the wireless charging instrument,
wherein the wireless charging instrument includes:
a wireless power transmission module configured to be movable and formed in a loop shape;
a control module;
at least one operating member moved along X-axis or Y-axis directions perpendicular to each other through a control of the control module; and
a rotary member rotatably coupled to the at least one operating member, and
wherein the wireless power transmission module is fixed to the rotary member, and
wherein a position of the wireless power transmission module is changed by the movement of the at least one operating member and rotated around a direction perpendicular to a movement direction of the at least one operating member.

2. The drone station of claim 1 ,
wherein the wireless charging instrument comprises: a power transmission coil for wirelessly transmitting a power to the drone positioned on the top.

3. The drone station of claim 2 , further comprising: a guide member spaced apart from the power transmission coil, and for generating an electromagnetic force to fix the drone positioned on the top of the wireless charging instrument.

4. The drone station of claim 3 ,
wherein the guide member is disposed on an outer circumference of the power transmission coil.

5. The drone station of claim 1 ,
wherein the landing guidance instrument is formed with an accommodation groove in which the wireless charging instrument is accommodated.

6. The drone station of claim 1 ,
wherein the landing guidance instrument further comprises: a vibration member for generating a vibration on a bottom of the inclined surface.

7. The drone station of claim 1 ,
wherein the landing guidance instrument further comprises: a rolling member composed of a plurality of spheres disposed on the inclined surface.

8. The drone station of claim 1 , further comprising: a protective cover for covering the drone positioned on the wireless charging instrument,
wherein the protective cover is changed to an opened state when the drone takes off and lands.

9. The drone station of claim 8 ,
wherein the protective cover comprises:
a rotary shaft;
a first cover rotated by a rotation of the rotary shaft; and
a second cover rotated by the rotation of the rotary shaft, and rotated in a direction opposite to the first cover.

10. The drone station of claim 1 ,
wherein the wireless power transmission module comprises: a wireless power transmission antenna for sending a power source in a wireless method, the wireless power transmission antenna being in a flat form around which a conductive member is wound in a loop shape.

11. The drone station of claim 10 ,
wherein the wireless power transmission module comprises: a shield sheet disposed on one surface of the wireless power transmission antenna.

12. The drone station of claim 11 ,
wherein the shield sheet is a flat-shaped sheet including at least one of a ferrite, a polymer, and an amorphous ribbon.

13. The drone station of claim 10 ,
wherein the wireless power transmission antenna is one of an antenna pattern patterned on one surface of a circuit board in a loop shape and a flat-shaped coil.

14. The drone station of claim 10 ,
wherein when a wireless power reception module of the drone and the wireless power transmission module are aligned, one end of a magnetic core is disposed to be positioned in a hollow portion formed in a central region of the wireless power transmission antenna.

15. The drone station of claim 1 ,
wherein one surface of the rotary member has two wireless power transmission modules disposed to be spaced apart from each other at a predetermined interval.
