Abstract:
A multirotor unmanned aerial vehicle, comprising a frame (10), forward-rotation rotors (20), and reverse-rotation rotors (30). Each forward-rotation rotor (20) comprises a first motor (21), a first propeller (22), and a first elastic member (23). Each reverse-rotation rotor (30) comprises a second motor (31), a second propeller (32), and a second elastic member (33). A propeller seat (221) of the first propeller (22) is provided with a first fastening portion (224), and the first propeller (22) can slide in the axial direction of the rotating shaft of the first motor (21), until the first elastic member (23) is fastened to the first fastening portion (224), so that the first propeller (22) is limited in the axial direction of the rotating shaft of the first motor (21). A propeller seat (321) of the second propeller (32) is provided with a second fastening portion, and the second propeller (32) can slide in the axial direction of the rotating shaft of the second motor (31), until the second elastic member (33) is fastened to the second fastening portion, so that the second propeller (32) is limited in the axial direction of the rotating shaft of the second motor (31). The second motor (31) drives, by means of the second fastening portion, the second propeller (32) to rotate. According to the multirotor unmanned aerial vehicle, the propellers can be kept in stable connection.
