[0002] To reduce the space occupied by a flying car when driving on the ground, the flying car usually installs the propeller inside the body contour, or folds the propeller into the body, and folds the wings, and stores the wings on both sides or the top of the body to reduce the space occupied by the wings in the width direction of the body.

[0003] The folding wing structure of the existing flying car usually adopts a combined structure of a fixed section and a movable section, wherein the fixed section is connected to the vehicle body, and the movable section is connected to the fixed section through a mechanical connection structure, so that the movable section and the fixed section are rotatably connected to realize the function of wing folding. In this folding wing structure, the mechanical connection structure between the movable section and the fixed section is a weak node in the wing because the functions to be realized are complex and the force-bearing situation is complex. Therefore, its structure design is complex and the weight is large, and this segmented wing structure has the problem of low reliability, which affects its market application on flying cars.

[0004] In addition, the folding wing often adopts a single-wing structure, and the force that the wing can provide for the flying car during flight is relatively limited, which limits the flight efficiency of the flying car. Summary of the Utility Model

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0037] Refer to Figure 1 , in some embodiments of the present utility model, the flying car includes:

[0038] Vehicle body;

[0039] A rotor assembly is provided on the vehicle body and is used to provide the lift required for takeoff and the power required for flight of the flying vehicle.

[0040] The wing assembly 10 includes at least two wings 101 arranged side by side, and the wing assembly is rotatably connected to the vehicle body, enabling the wing assembly to rotate and switch between two setting states along the length direction and the width direction of the vehicle body.

[0041] Taking Figure 1 the flying vehicle shown as an example, the wing assembly 10 includes two wings 101 arranged side by side at intervals, and the two wings form a tandem wing structure. The whole wing assembly is rotatably connected to the vehicle body and can rotate along the Z direction of the vehicle body. In the flight state, the wing assembly rotates to the setting state arranged along the width direction of the vehicle body, making the wing assembly perpendicular to the flight direction of the flying vehicle and providing the lift required for flight of the flying vehicle; when the flying vehicle lands or the flying vehicle is driving on the ground, the wing assembly rotates to the setting state arranged along the length direction of the vehicle body, and the wing assembly is rotated and stored within the contour range of the vehicle body to reduce the space occupied by the flying vehicle.

[0042] Since the wing assembly is rotatably connected to the vehicle body, the wing assembly structure has better integrity, is simpler in structural design and has better overall structural strength, and can provide a larger design space for the design of the wing assembly.

[0043] Taking Figure 1 the tandem wing structure shown as an example, the wing assembly 10 adopts two wings 101, and the two wings 101 are arranged parallel at intervals. Compared with the single-wing structure, the two wings can provide greater additional lift for the flying vehicle during flight, which plays an important role in improving the flight efficiency and endurance time of the flying vehicle. Moreover, the rotational connection method between the wing assembly and the vehicle body will not increase the difficulty of the structural design of the wing assembly and the installation of the wing assembly on the vehicle body, and has good practical and market application value.

[0044] In some embodiments, the vehicle body includes a chassis assembly 20 and a cab 30, and the wing assembly 10 is arranged on the top of the cab 30 and is rotatably connected to the top of the cab to facilitate the arrangement of the wing assembly on the vehicle body.

[0045] In some embodiments, for the rotational connection structure between the wing assembly and the cab, referring to Figure 2 and Figure 3 , a slewing bearing 501 can be arranged on the top of the cab. The slewing bearing 501 includes an outer bearing ring 503 and an inner bearing ring 502, and the outer bearing ring 503 is fixedly arranged on the top of the cab.

[0046] The wing assembly includes a connecting plate 102, and two wings 101 are respectively fixedly arranged on the connecting plate 102. The connecting plate 102 is fixedly connected to the inner ring 502 of the bearing.

[0047] A driving unit is arranged in the cab or on the top of the cab. The driving unit is used to drive the inner ring of the bearing to rotate. When the driving unit drives the inner ring of the bearing to rotate, it can realize the rotational drive of the wing assembly and realize the rotational switching of the wing assembly between two set states.

[0048] In some embodiments, the driving unit includes a motor 504 arranged on the top of the cab. Meshing transmission gears (not shown in the figure) are respectively arranged on the rotating shafts of the inner ring 502 of the bearing and the motor 504. Through the transmission cooperation between the motor and the transmission gears, when the motor drives the inner ring of the bearing to rotate, the rotational drive of the wing assembly can be realized.

[0049] In some embodiments, a locking unit is arranged between the wing assembly and the vehicle body. The locking unit is used to lock the rotation of the wing assembly when the wing assembly rotates to two set states, fix the wing assembly in the current set state, and limit the rotation of the wing assembly.

[0050] The locking unit can adopt a structure for locking the inner ring of the bearing or locking the wing assembly. Taking the structure for locking the wing assembly as an example, a telescopic pin shaft can be arranged on the top of the cab. When it is necessary to lock the wing assembly, control the pin shaft to extend and insert the pin shaft into the pin hole arranged on the connecting plate of the wing assembly, and the locking of the wing assembly in the current set state can be realized. When the pin shaft is controlled to withdraw from the pin hole, the locking of the wing assembly can be released.

[0051] In some embodiments, the rotor assembly includes two groups of rotor units 40, and each rotor unit 40 includes a plurality of rotors 401. Figure 4 Taking the shown structure as an example, each group of rotor units is composed of three rotors arranged in a triangular shape. When the rotors rotate, they provide the power required for the flying car to take off and fly.

[0052] The chassis assembly 20 is set as a frame structure. Two groups of rotor units 40 are respectively arranged at the front and rear ends of the chassis assembly and are located within the frame structure of the chassis assembly. A space for installing the rotors is arranged inside the chassis assembly, avoiding the increase in the vehicle body size caused by the setting of the rotors and reducing the space occupied by the flying car.

[0053] The three rotors in the rotor unit are arranged in an isosceles triangle with the X-axis central line of the vehicle body as the reference. The two groups of rotor units are symmetrically arranged on the chassis assembly with the Y-axis central line of the vehicle body as the reference to further optimize the structure of the chassis assembly and the setting of the rotor assembly on the chassis assembly.

[0054] In some embodiments, with reference to Figure 4 and Figure 5 , a wheel assembly is provided on the chassis assembly 20. The wheel assembly includes two drive wheels 601 oppositely arranged along the width direction of the chassis assembly and two auxiliary wheels 602 oppositely arranged along the length direction of the chassis assembly. The two drive wheels 601 and the two auxiliary wheels 602 are arranged in a diamond shape on the chassis assembly. Among them, the auxiliary wheels 602 are universal wheels or steering wheels connected to a steering mechanism.

[0055] A wheel drive unit is provided on the chassis assembly. The wheel drive unit is used to drive the two drive wheels and can independently drive the two drive wheels respectively.

[0056] The wheel drive unit can adopt hub motors respectively connected to the two drive wheels. The two drive wheels can be respectively driven by the corresponding hub motors. When the hub motors drive the two drive wheels to move, they provide power for the flying car to travel on the ground. By independently controlling the rotation or rotation speed of the drive wheels respectively through the hub motors, the steering of the flying car can be achieved through the speed difference between the two drive wheels, or the steering wheels can be steered through the steering mechanism.

[0057] The drive wheels are directly provided on the chassis assembly or connected through shock absorbers.

[0058] The two auxiliary wheels and the two drive wheels provide stable support for the vehicle body during the driving state. During steering, the two auxiliary wheels can facilitate the steering of the flying car.

[0059] When in the ground driving state, the wing assembly rotates to be arranged along the length direction of the vehicle body. At this time, the wing assembly is received into the vehicle body contour, reducing the occupied space of the flying vehicle.

[0060] When switching to the flying state, start the rotor assembly to make the flying car vertically lift off. After reaching a certain height, drive the wing assembly to rotate 90° through the motor. The wing assembly rotates to be arranged along the width direction of the vehicle body. At this time, drive the flying car to fly through the rotor assembly, and at the same time, the wing assembly provides additional lift for the flying car.

[0061] When landing, control the flying car to hover in the air through the rotor assembly. Drive the wing assembly to rotate 90° through the motor. The wing assembly rotates to be arranged along the length direction of the vehicle body to realize the storage of the wings. Control the rotation speed of the rotor assembly to make the flying car land, and then it can be switched back to the ground driving state again.
