Abstract: An energy-load assembly includes an accommodating box, a power source, a load and an undercarriage. The accommodating box can be connected to a body of an unmanned aerial vehicle; the power source is arranged in the accommodating box, and can provide electric energy to the unmanned aerial vehicle; the load is arranged at the bottom of the accommodating box; and the undercarriage is connected to the accommodating box. The energy-load assembly provided integrates the power source, the load and the undercarriage. The corresponding power source and the load can be integrated according to different tasks performed.

Abstract: A motor with an outer rotor, including an inner stator, an outer rotor with a cylindrical structure having an open end, a controller, and a cooling fan. The outer rotor is rotatably sleeved at one end of the inner stator in an axial direction of the inner stator; the controller is arranged at the other end of the inner stator; the cooling fan is annularly arranged in a circumferential direction of the outer rotor at one end of the outer rotor close to the controller, and is located in an avoidance space formed between the controller and the outer rotor, so as to convey air to the controller and the outer rotor.

Abstract: A disassembling structure includes a first connecting piece, a second connecting piece and a guide and positioning piece; the guide and positioning piece is fixedly arranged on the first module; the second connecting piece is fixedly arranged on the second module; the second connecting piece and the guide and positioning piece are opposite to each other; the guide and positioning piece is attached to the outer side of the second connecting piece in a covering manner to guide and position the first module and the second module; the first connecting piece is detachably connected to the second connecting piece after passing through the guide and positioning piece.

Abstract: A conductive fastening mechanism including a nut connected to an energy load module and electrically connected to a power supply through a power switch S0; an anti-rotating seat located above the nut; a conducting element arranged in the anti-rotating seat and electrically connected to a load; a connecting piece penetrating the anti-rotating seat and the conducting element and selectively connected to the nut, used for on-off between the load and the power supply; a handle rotatably arranged on the connecting piece, where the handle is configured to be selectively clamped in the anti-rotating seat to limit the connecting piece. The handle is rotatably arranged on the connecting piece and can be selectively clamped on the anti-rotating seat, such that the handle plays a role in preventing the connecting piece from rotating, so as to achieve the purpose of anti-vibration and anti-loosening, prevent damage and other safety accidents, and improve safety.
