firstly, in the vertical takeoff process, please refer to fig. 21, the rearview mirror 111 rotates into the vehicle body 10 to reduce the resistance; the front power compartment door 106 is opened and the front power system 201 is enabled to work; the wing cabin door 104 is opened, the rotary front wing 301 is driven by the front wing rotary motor 306 to rotate from the wing cabin door 104 to the outside of the vehicle body 10, the overturning front wing 302 is driven by the hydraulic hinge assembly 70 to overturn, so that the folding wing 30 is unfolded, and the wing cabin door 104 is partially closed after being unfolded; the rear cover 103 rotates, the folding wing tail front section 401 and the folding wing tail rear section 402 rotate and then extend, the folding wing tail 40 is unfolded, meanwhile, the power turnover rod 207 is turned over to the outside of the vehicle body 10, so that the first main power system 202 and the second main power system 203 are unfolded, the first main power system 202 and the second main power system 203 work, and then the rear cover 103 reversely rotates, so that the folding wing tail rear section 402 forms a lifting body wing shape together with the folding wing tail front section 401, the bottom side of the vehicle body 10 and the turned rear cover 103; so that the hovercar takes off along the vertical direction under the drive of the front power system 201, the first main power system 202 and the second main power system 203; after vertical take-off, the wheels 604 are folded to the horizontal direction under the action of the wheel cover 601 to reduce the resistance.

Referring to fig. 22, after the flying automobile vertically takes off to a predetermined height, the spiral power assemblies 205 in the first main power system 202 and the second main power system 203 rotate around the corresponding power turnover rods 207, so that the power directions of the first main power system 202 and the second main power system 203 are changed from vertical downward to oblique downward, forward horizontal thrust and upward lift are provided for the flying automobile, and at this time, the flying automobile enters a transition state in the flying process.

Thirdly, in a flight cruising state, referring to fig. 23, after the flying vehicle reaches a certain forward speed, the front power system 201 and the front power cabin door 106 are closed, and meanwhile, the spiral power assemblies 205 in the first main power system 202 and the second main power system 203 continue to rotate around the corresponding power turnover rods 207 until the power directions of the first main power system 202 and the second main power system 203 become the horizontal direction, and at this time, the flying vehicle enters a cruising state.

(3) And (3) a landing process: the landing process is the reverse movement of the takeoff process.

In the flight transition state, referring to fig. 24, the front power system 201 and the front power cabin door 106 are opened, so that the front power system 201 provides an upward lift force, and simultaneously, the spiral power assemblies 205 in the first main power system 202 and the second main power system 203 reversely rotate around the corresponding power turnover rods 207, so that the power directions of the first main power system 202 and the second main power system 203 are changed from vertical downward to oblique downward, so that the flight speed of the hovercar is gradually reduced, and thus, the hovercar enters the flight transition state from the flight cruise state.

In the vertical landing process, referring to fig. 25, the spiral power assemblies 205 in the first main power system 202 and the second main power system 203 continue to rotate reversely around the corresponding power turnover rods 207 until the power directions of the first main power system 202 and the second main power system 203 change to the vertical direction, and at this time, the flying automobile is in a hovering state; the wheels 604 are folded to the vertical direction under the action of the wheel covers 601, and the lift force of the front power system 201, the first main power system 202 and the second main power system 203 is adjusted, so that the aerocar slowly descends until the aerocar lands on the ground;

referring to fig. 26, after landing on the ground, the rear view mirror 111 rotates to the outside of the vehicle body 10, the front power system 201, the first main power system 202 and the second main power system 203 are all closed, the front power cabin door 106 is closed, the wing cabin door 104 is opened, the reversed front wing 302 is reversed, then the rotary front wing 301 rotates to store the folded wing 30 into the vehicle body 10, and then the wing cabin door 104 is completely closed; the rear cover 103 is opened, the power turnover rod 207 is turned and folded into the vehicle body 10, the front section 401 and the rear section 402 of the folding wing tail are folded into the vehicle body 10, and then the rear cover 103 is closed to enter a ground driving state.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
