Abstract

An example charging station for an unmanned aerial vehicle (UAV), the charging station generally including a nest and a charging device. The nest includes an upper portion and a lower portion. The upper portion defines an upper opening sized and shaped to receive a landing apparatus of the UAV, and a diameter of the nest reduces from a first diameter at the upper opening to a second diameter at the lower portion. The charging device is mounted in the nest, and includes a first contact pad and a second contact pad. The charging device is configured to apply a voltage differential across the first contact pad and the second contact pad such that the charging station is operable to charge a power supply of the UAV via the landing apparatus.

First claim

What is claimed is:

1. A charging station for a plurality of unmanned aerial vehicles (UAVs), the plurality of UAVs comprising a first UAV and a second UAV, the charging station comprising:
a nest including an upper portion and a lower portion, wherein the upper portion defines an upper opening, wherein the nest has a greater diameter at the upper opening and a lesser diameter at the lower portion, wherein the nest defines a first rest position for the first UAV, wherein the nest defines a second rest position for the second UAV, and wherein the second rest position is vertically offset from the first rest position; and
a charger mounted in the nest, wherein the charger is configured to charge a first power supply of the first UAV when the first UAV is in the first rest position, and wherein the charger is configured to charge a second power supply of the second UAV when the second UAV is in the second rest position.

2. The charging station of claim 1 , wherein the charger is configured to contact a first charge terminal of the first UAV when the first UAV is in the first rest position, and to charge the first power supply via the first charge terminal; and
wherein the charger is configured to contact a second charge terminal of the second UAV when the second UAV is in the second rest position, and to charge the second power supply via the second charge terminal.

3. The charging station of claim 2 , wherein the charger is configured to contact a third charge terminal of the first UAV when the first UAV is in the first rest position, and to charge the first power supply by applying a first voltage differential across the first charge terminal and the third charge terminal; and
wherein the charger is configured to contact a fourth charge terminal of the second UAV when the second UAV is in the second rest position, and to charge the second power supply by applying a second voltage differential across the second charge terminal and the fourth charge terminal.

4. The charging station of claim 3 , wherein the charger comprises:
a first contact pad configured to contact the first charge terminal when the first UAV is in the first rest position and to contact the second charge terminal when the second UAV is in the second rest position; and
a second contact pad configured to contact the third charge terminal when the first UAV is in the first rest position and to contact the fourth charge terminal when the second UAV is in the second rest position;
wherein the charger is operable to apply each of the first voltage differential and the second voltage differential across the first contact pad and the second contact pad.

5. The charging station of claim 1 , wherein the charger comprises a first contact pad and a second contact pad, and is operable to charge each of the first power supply and the second power supply by applying one or more voltage differentials across the first contact pad and the second contact pad.

6. The charging station of claim 5 , wherein each of the first contact pad and the second contact pad extends along a sidewall of the nest.

7. The charging station of claim 6 , wherein the sidewall is angled or curved relative to a central nest axis of the nest.

8. The charging station of claim 1 , wherein the nest is substantially frustoconical.

9. A system comprising the charging station of claim 1 , the system further comprising the plurality of UAVs.

10. The system of claim 8 , wherein the second UAV is larger than the first UAV.

11. A charging station for a plurality of unmanned aerial vehicles (UAVs), the plurality of UAVs comprising a first UAV and a second UAV, the charging station comprising:
a nest that defines a first rest position for the first UAV and a second rest position for the second UAV, wherein the first rest position is located above the second rest position; and
a charger positioned at least partially in the nest, wherein the charger is operable to charge a first power supply of the first UAV when the first UAV is in the first rest position, and wherein the charger is operable to charge a second power supply of the second UAV when the second UAV is in the second rest position.

12. The charging station of claim 11 , wherein the nest is tapered and/or curved inward relative to a central nest axis from a greater upper diameter to a lesser lower diameter.

13. The charging station of claim 11 , wherein the charger comprises a first contact pad and a second contact pad, wherein each of the first contact pad and the second contact pad extends vertically and away from a central nest axis of the nest.

14. The charging station of claim 13 , wherein the charger is configured to apply one or more voltage differentials across the first contact pad and the second contact pad to thereby charge the first power supply and the second power supply.

15. A system comprising the charging station of claim 11 , wherein the system further comprises the plurality of UAVs.

16. The system of claim 15 , wherein the first UAV is larger than the second UAV.

17. A method of operating a charging station comprising a nest and a charger, the method comprising:
receiving a first unmanned aerial vehicle (UAV) within the nest such that the first UAV comes to rest at a first rest position;
with the first UAV in the first rest position, operating the charger to thereby charge a first power supply of the first UAV;
receiving a second UAV within the nest such that the second UAV comes to rest at a second rest position vertically offset from the first rest position; and
with the second UAV in the second rest position, operating the charger to thereby charge a second power supply of the second UAV.

18. The method of claim 17 , further comprising:
during descent of the first UAV, urging, by a sidewall of the nest, the first UAV toward the first rest position and toward a central nest axis of the nest; and
during descent of the second UAV, urging, by the sidewall of the nest, the second UAV toward the second rest position and toward the central nest axis of the nest.

19. The method of claim 17 , wherein the first UAV comprises a first landing apparatus having a first effective diameter; and
wherein the second UAV comprises a second landing apparatus having a second effective diameter different from the first effective diameter.

20. The method of claim 17 , wherein the charger comprises:
a first contact pad that extends upward and away from a central nest axis of the nest and along a sidewall of the nest; and
a second contact pad that extends upward and away from the central nest axis and along the sidewall.
