Abstract
A multi-rotor aircraft (100) is provided, comprising: a main aircraft assembly (10) comprising a first magnetic medium (13), a main housing (11), and a control motherboard accommodated in the main housing (11), wherein the first magnetic medium (13) is provided on the main housing (11), a slot (1120) is further provided on the main housing (11), and a connection point of the control motherboard is provided in the slot (1120); and a plurality of rotor systems (20), wherein each of the plurality of rotor systems comprises a second magnetic medium (23), a rotor mechanism (21), and a rotor protection cover (22) that is of a hollow annular structure and is fixed outside the rotor mechanism (21), wherein the second magnetic medium (23) is fixed to the rotor protection cover (22) and attracting the first magnetic medium (13), and a pin (2200) matching the slot (1120) is further provided on the rotor protection cover (22). The rotor systems (20) can be quickly mounted on or dismounted from the main aircraft assembly (10), thereby achieving the technical effects of shortening the mounting and dismounting time and improving the operation efficiency.
