This disclosure provides an aircraft vehicle, which comprises a circuit board, and at least one power component mounted on said circuit board. The at least one power component comprises a rotor, a drive unit and a fixing sleeve. Said drive unit is electrically connected to said circuit board and drives the rotor to rotate. Said fixing sleeve comprises a receiving space with an opening at a top. Said fixing sleeve comprises at least one first stopping piece and at least one second stopping piece projected on an outer surface of the fixing sleeve. Said drive unit is accommodated in the receiving space and is secured in the fixing sleeve. Said circuit board comprises at least one positioning hole corresponding to the power component. The fixing sleeve is configured to pass through the positioning hole so that the circuit board is retained between the first stopping piece and the second stopping piece. This disclosure also provides a fixing sleeve. Thus, when the aircraft vehicle falls or collides with another object, the fixing sleeve ensures that the drive unit does not separate from the circuit board, therefore enhancing the performance of the aircraft vehicle. |
