Abstract

The present disclosure is directed toward systems and methods for inserting and removing a battery assembly from an unmanned aerial vehicle (UAV) and/or a UAV ground station (UAVGS). For example, systems and methods described herein enable convenient installation of a battery assembly within a UAV. The battery assembly and UAV further include features that facilitate secure connection of the battery assembly within the UAV and which prevents wear due to frequent installation and removal of the battery assembly within a receiving slot of the UAV. In one or more embodiments, the battery assembly includes a housing and one or more connectors having one or more features that cause the battery assembly to self-align when the battery assembly is inserted within the receiving slot of the UAV.

Claims

1. A self-aligning battery assembly for an unmanned aerial vehicle (UAV), comprising:

a housing having a first end and a second end, the housing being sized to fit into a receiving slot of the UAV, wherein the housing has a shape that causes the housing to self-align within the receiving slot within a first tolerance level when the housing is inserted into the receiving slot;

a power connector positioned at a first end of the housing, the power connector sized to engage with a corresponding power contact within the receiving slot of the UAV, wherein the power connector has a shape that causes the housing to self-align from the first tolerance level to a second tolerance level when the power connector engages the corresponding power contact when the housing is inserted into the receiving slot; and

a data connector positioned at the first end of the housing, the data connector sized to engage a corresponding data contact within the receiving slot of the UAV, wherein the data connector is positioned to engage the corresponding data contact when the housing self-aligns within the second tolerance level when the housing is inserted into the receiving slot.

2. The self-aligning battery assembly as recited in claim 1, wherein the first tolerance level is less precise than the second tolerance level.

3. The self-aligning battery assembly as recited in claim 2, wherein the first tolerance level is less precise by a factor of ten or more than the second tolerance level.

4. The self-aligning battery assembly as recited in claim 1, wherein a dimension of the housing at the first end of the housing is less than a corresponding dimension of the housing at the second end of the housing.

5. The self-aligning battery assembly as recited in claim 4, wherein the shape of the housing comprises a gradual change between the dimension of the housing at the first end of the housing to the corresponding dimension of the housing at the second end of the housing.

6. The self-aligning battery assembly as recited in claim 4, wherein the shape of the housing comprises a change between the dimensions of the housing at the first end to the corresponding dimension of the housing at the second end, the change in between the dimensions occurring toward the first end of the housing.

7. The self-aligning battery assembly as recited in claim 1, wherein the power connector protrudes from an outward surface of the first end of the housing.

8. The self-aligning battery assembly as recited in claim 7, wherein the power connector protrudes from the outward surface of the first end of the housing beyond a point of engagement of the data connector.

9. The self-aligning battery assembly as recited in claim 1, wherein the data connector forms a recess in an outer surface of the first end of the housing.

10. The self-aligning battery assembly as recited in claim 1, wherein the data connector comprises a universal serial bus (USB) port.

11. The self-aligning battery assembly as recited in claim 1, wherein the power connector provides power to a camera component and a flying component of the UAV.

12. The self-aligning battery assembly as recited in claim 1, wherein the shape of the housing causes the housing to self-align within the receiving slot within the first tolerance level without forming an electrical connection between the power connector and the corresponding power contact or the data connector and the corresponding data contact.

13. The self-aligning battery assembly as recited in claim 1, further comprising one or more additional power connectors sized to engage one or more additional corresponding power contacts within the receiving slot of the UAV.

14. An unmanned aerial vehicle (UAV) system comprising:

a main body;

one or more rotors coupled to the main body;

at least one camera coupled to the main body;

a receiving slot within the main body, the receiving slot comprising;

an opening at a first end of the receiving slot, the opening being sized to receive a battery assembly;

an interior portion of the receiving slot, the interior portion shaped to cause the battery assembly to self-align within a first tolerance level when the battery assembly is inserted into the receiving slot.

a power contact at a second end of the receiving slot, the power contact positioned within the receiving slot to receive a power connector on the battery assembly when the battery assembly aligns within the first tolerance level, wherein the power contact further causes the battery assembly to self-align within a second tolerance level when the battery assembly is inserted into the receiving slot; and

a data contact at the second end of the receiving slot, the data contact positioned within the receiving slot to engage a data connector on the battery assembly when the battery assembly aligned within the second tolerance level.

15. The UAV system as recited in claim 14, further comprising:

a landing system coupled to the main body; and

a UAV ground station (UAVGS) having a receiving cone shaped to receive the landing system.

16. The UAV system as recite in claim 15, wherein the UAVGS comprises one or more battery docks shaped to receive the battery assembly.

17. The UAV system as recited in claim 16, wherein the one or more battery docks on the UAVGS are shaped to cause the battery assembly to self-align when the battery assembly is inserted within the one or more battery docks on the UAVGS.

18. A method for replacing a dual-connector battery assembly for an unmanned aerial vehicle (UAV), the method comprising:

engaging an end of a battery assembly, the battery assembly comprising a power connector and a data connector positioned on a first end of the battery assembly;

placing the battery assembly into an opening of a receiving slot, the receiving slot having a power contact corresponding to the power connector and a data contact corresponding to the data connector, wherein the receiving slot is sized to receive the housing of the battery assembly;

inserting the battery assembly into the receiving slot, wherein a shape of the housing causes the battery assembly to self-align within a first tolerance level as the battery assembly is inserted within the receiving slot; and

when the battery assembly is aligned within the first tolerance level, connecting the power connector to the corresponding power contact, wherein connecting the power connector to the corresponding power contacts causes the battery assembly to further self-align from within the first tolerance level to within a second tolerance level;

when the battery assembly is aligned within the second tolerance level, connecting the data connector to the corresponding data contact.

19. The method as recited in claim 18, further comprising:

extracting the battery assembly from the receiving slot, wherein extracting the battery assembly from the receiving slot comprises;

gripping the end of the battery assembly; and

pulling the battery assembly from the receiving slot, wherein pulling the battery assembly from the receiving slot causes the data connector to disconnect from the corresponding data contact and the power connector to disconnect from the corresponding power contact;

20. The method as recited in claim 19, further comprising:

inserting the battery assembly into a receiving slot on a UAV ground station (UAVGS), inserting the battery assembly into a receiving slot on the UAVGS comprises;

gripping the end of the battery assembly;

placing the battery assembly into an opening of the receiving slot of the UAVGS, the receiving slot of the UAVGS sized to receive the housing of the battery assembly.
