Abstract

An unmanned aerial vehicle includes a fuselage and a power supply assembly arranged at the fuselage. The power supply assembly includes a polyhedron mounting bracket arranged at the fuselage, a power supply device arranged at the fuselage, and at least two functional circuits arranged separately on different outer surfaces of the mounting bracket and electrically coupled to each other and to the power supply device.

First claim

What is claimed is:

1. An unmanned aerial vehicle (UAV) comprising:
a fuselage; and
a power supply assembly arranged at the fuselage and including:
a polyhedron mounting bracket arranged at the fuselage;
a power supply device arranged at the fuselage; and
at least two functional circuits arranged separately on different outer surfaces of the mounting bracket and electrically coupled to each other and to the power supply device.

2. The UAV of claim 1 , wherein:
the fuselage includes a housing; and
the power supply assembly is arranged inside the housing.

3. The UAV of claim 1 , wherein:
the fuselage includes an upper housing and a lower housing interlocked with each other; and
the power supply assembly is arranged between the upper housing and the lower housing.

4. The UAV of claim 3 , further comprising:
one or more controlling devices arranged at the lower housing and corresponding to the mounting bracket.

5. The UAV of claim 4 , wherein:
the one or more controlling devices include a first controlling device fixedly stacked on the lower housing and the first controlling device includes a circuit board.

6. The UAV of claim 5 , wherein:
the one or more controlling devices further include a second controlling device stacked on the first controlling device and the second controlling device includes a circuit board.

7. The UAV of claim 4 , further comprising:
a heat radiator provided at the lower housing and adjacent to the one or more controlling devices.

8. The UAV of claim 7 , wherein:
the one or more controlling devices and the heat radiator are separately fixed on the lower housing to form a lower housing assembly with the lower housing; or
the lower housing includes:
a first housing member interlocked with the upper housing; and
a second housing member detachably coupled to the first housing member.

9. The UAV of claim 7 , wherein:
the one or more controlling devices and the heat radiator are separately fixed on the second housing member.

10. The UAV of claim 3 , wherein the lower housing includes:
a first housing member interlocked with the upper housing; and
a second housing member detachably coupled to the first housing member.

11. The UAV of claim 10 , wherein:
the first housing member includes a mounting hatch extending through the first housing member and communicating with a receiving cavity of the fuselage, and the second housing member is arranged at the mounting hatch; or
the UAV carries an image acquisition device that is connected to the second housing member of the fuselage; or
a landing stand arranged at the first housing member and extending away from the fuselage.

12. The UAV of claim 1 , wherein the at least two functional circuits are configured to perform different functions.

13. The UAV of claim 12 , wherein each of the at least two functional circuits includes at least one of a speed sensing circuit, a gravity sensing circuit, a visual sensing circuit, a magnetic field sensing circuit, or a control circuit.

14. The UAV of claim 12 , wherein the at least two functional circuits include a first circuit board and a second circuit board separately arranged on opposite sides of the mounting bracket.

15. The UAV of claim 14 , wherein:
the power supply device is arranged inside the mounting bracket; and
the first circuit board and the second circuit board are stacked on outer surfaces of the opposite sides of the mounting bracket, respectively.

16. The UAV of claim 15 , wherein:
the power supply device further includes an adapter arranged at an end of the mounting bracket and electrically coupled to the power supply device.

17. The UAV of claim 16 , wherein:
the adapter is stacked on an outer side of the mounting bracket, and two opposite side edges of the adapter are adjacent to the first circuit board and the second circuit board, respectively; or
the adapter includes a standard interface electrically coupled to the power supply device.

18. The UAV of claim 15 , wherein:
the at least two functional circuits further includes a third circuit board arranged at the mounting bracket and separate from the first circuit board and the second circuit board; and
the third circuit is electrically coupled to the power supply device.

19. The UAV of claim 18 , wherein:
the third circuit board is stacked on an outer surface of a side of the mounting bracket; and
three side edges of the third circuit board are adjacent to the first circuit board, the second circuit board, and the adaptor, respectively.

20. The UAV of claim 19 , wherein:
the power supply assembly further includes a controller arranged on a side of the third circuit board away from the mounting bracket;
the controller is electrically coupled to the power supply device; and
both ends of the controller extend relative to corresponding ends of the third circuit board and are electrically coupled to the power supply device.
