Abstract

A landing pad for an unmanned aerial vehicle (“UAV”) is disclosed. The landing pad includes a support structure, a charging pad, and a plurality of movable UAV supports. The charging pad is coupled to the support structure and able to move relative to the support structure. The UAV supports are also coupled to the support structure and configured to translate along the support structure from a first position to a second position. When the UAV supports are in the first position, the charging pad supports the UAV. When the UAV supports are in the second position, the charging pad is lowered and the UAV supports then provide support to the UAV.

First claim

We claim:

1. A landing pad for an unmanned aerial vehicle (“UAV”), comprising:
a support structure;
a charging pad coupled to the support structure such that at least a portion of the charging pad is configured to move relative to the support structure; and
a plurality of UAV supports coupled to the support structure, wherein the plurality of UAV supports are configured to translate along the support structure from a first position to a second position, wherein when in the first position the plurality of UAV supports provide the UAV access to the charging pad and the charging pad supports the UAV, and wherein when in the second position the plurality of UAV supports support the UAV,
wherein each of the plurality of UAV supports are force limited such that the plurality of UAV supports are configured to translate along the support structure until the plurality of UAV supports contact the UAV but do not cause the UAV to change position.

2. The landing pad of claim 1 , wherein when the plurality of UAV supports are in the second position, the charging pad is configured to move away from the UAV such that an underside of the UAV is accessible.

3. The landing pad of claim 1 , wherein the UAV is configured to load a payload when the plurality of UAV supports are in the second position.

4. The landing pad of claim 1 , wherein the plurality of UAV supports are configured to translate along the support structure until each of the plurality of UAV supports contacts the UAV.

5. The landing pad of claim 1 , wherein when in the second position, each of the plurality of UAV supports is in contact with the UAV.

6. The landing pad of claim 1 , wherein the UAV is configured to land on the landing pad when the plurality of UAV supports are in the first position.

7. The landing pad of claim 1 , wherein the UAV is configured to takeoff from the landing pad when the plurality of UAV supports are in a third position.

8. The landing pad of claim 1 , wherein the UAV is configured to deploy a payload coupling apparatus when the plurality of UAV supports are in the second position.

9. The landing pad of claim 1 , wherein the plurality of UAV supports are configured to translate along the support structure for a predetermined amount of time.

10. The landing pad of claim 1 , wherein the charging pad is configured to charge a battery of the UAV when the plurality of UAV supports are in the first position.

11. The landing pad of claim 1 , wherein each of the plurality of UAV supports comprises a roller, wherein the roller spans the charging pad, and wherein the roller is configured to roll along a portion of the support structure.

12. The landing pad of claim 1 , wherein each of the plurality of UAV supports comprises a gear wheel coupled to a bar, wherein the bar spans the charging pad, and wherein the support structure comprises a track corresponding to the gear wheel.

13. The landing pad of claim 1 , wherein the plurality of UAV supports are located along a periphery of the charging pad when in the first position.

14. The landing pad of claim 1 , wherein the plurality of UAV supports comprises:
a first pair of UAV supports that move in opposite directions to one another; and
a second pair of UAV supports that move in opposite directions to one another, wherein the first pair of UAV supports are pendicular to the second pair of UAV supports.

15. A method, comprising:
supporting an unmanned aerial vehicle (“UAV”) above a ground surface by a charging pad of a landing pad;
moving a plurality of UAV supports across the landing pad towards the UAV, wherein each of the plurality of UAV supports moves in a different direction; and
after moving the plurality of UAV supports towards the UAV, moving the charging pad away from the UAV such that the UAV is no longer supported by the charging pad and the plurality of UAV supports support the UAV above the ground surface.

16. The method of claim 15 , further comprising:
loading a payload to the UAV after the charging pad has moved away from the UAV and the UAV is supported by the plurality of UAV supports.

17. The method of claim 16 , further comprising:
after loading the payload to the UAV, initiating a takeoff of the UAV; and
after initiating the takeoff, moving the plurality of UAV supports away from the UAV such that the UAV is no longer supported by the plurality of UAV supports.

18. The method of claim 15 , wherein the moving the plurality of UAV supports across the landing pad towards the UAV stops when the plurality of UAV supports contact the UAV.

19. A payload loading system, comprising:
an unmanned aerial vehicle (UAV) that comprises a fuselage and a retractable tether, wherein a distal end of the tether is coupled to a payload coupling apparatus, and a proximate end of the tether is coupled to the UAV; and
a landing pad, comprising:
a support structure;
a charging pad coupled to the support structure such that at least a portion of the charging pad is configured to move relative to the support structure; and
a plurality of UAV supports coupled to the support structure, wherein the plurality of UAV supports translate along the support structure from a first position to a second position, wherein when in the first position the plurality of UAV supports provide the UAV access to the charging pad and the charging pad supports the UAV, and wherein when in the second position the plurality of UAV supports are in contact with the fuselage of the UAV
wherein each of the plurality of UAV supports are force limited such that the plurality of UAV supports are configured to translate along the support structure until the plurality of UAV supports contact the UAV but do not cause the UAV to change position.
