When the automobile mode and the flight mode are switched, whether the planet carrier brake band is tightened or not or whether the gear ring brake band is tightened or not can be correspondingly controlled by controlling the working state of the planet carrier brake band piston cylinder and the working state of the gear ring brake band piston cylinder so as to fix the planet carrier or the wheel, and therefore the output power of the hub motor is transmitted to the wheel or the propeller shaft to achieve the automobile mode or the flight mode. In addition, the propeller fan blades can stretch out and draw back under the action of the return springs, so that the propeller occupies a small space and is convenient to be arranged integrally with the wheels.
The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiments according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
