When the first driving member 4 is driven, the coil on the stator 41 generates a magnetic field after being energized, and the rotor 42 generates torque and rotates in the magnetic field of the stator 41, converting electrical energy into mechanical energy, and transmitting power to the wheel 2 and the propeller 5 through the central shaft 6.

[0085] In one embodiment, the clutch mechanism 3 includes a first clutch 31 and a second clutch 32 ; the first clutch 31 is connected to the wheel 2 , and the second clutch 32 is connected to the rotor 42 ; the second clutch 32 is energized to drive the first clutch 31 to drive the wheel 2 to rotate.

[0086] The first clutch 31 and the second clutch 32 are provided so that the clutch mechanism 3 can control the power transmission between the wheel 2 and the first drive member 4; when the vehicle body 8 is traveling on water, the clutch mechanism 3 disconnects the power transmission between the wheel 2 and the first drive member 4, and the wheel 2 does not rotate when traveling on water; when the vehicle body 8 is traveling on land and the wheel 2 needs to participate in the movement, the clutch mechanism 3 connects the power transmission between the wheel 2 and the first drive member 4, and the wheel 2 rotates when traveling on land to provide power to the vehicle body 8. Please refer to Fig.11 , the lower end of the first clutch 31 is connected to the second clutch 32, and the upper end is connected to the wheel 2; the lower end of the second clutch 32 is connected to the rotor 42, and the upper end is connected to the first clutch 31. The first clutch 31 is a permanent magnet, and the second clutch 32 is an electromagnet. Through the connection of the wheel 2, the first clutch 31, the second clutch 32 and the rotor 42, the synchronous rotation mode and the asynchronous rotation mode of the wheel 2 and the first driving member 4 can be realized. The synchronous rotation mode is that when the second clutch 32 is powered on, a magnetic field is generated, driving the first clutch 31 to rotate together, so that the wheel 2 is driven to rotate when the first driving member 4 rotates. The asynchronous rotation mode is that when the second clutch 32 is powered off, the magnetic field disappears, and the first clutch 31 cannot be driven to rotate together, so that the wheel 2 cannot be driven to rotate when the first driving member 4 rotates.
