The front side wall assembly 110 and the rear side wall assembly 100 are both connected to the frame 41, and are arranged in front and back along the travel direction of the vehicle body shell 20.

[0021] The land travel system 80 can comprise a track, a wheel or other structure connected to the vehicle body shell 20 and the vehicle frame 40, which can provide power for the flying car 200 to travel on land under the driving of a driving mechanism.

[0022] The flight system 60 comprises a support frame 61, four arms 65 and four groups of rotor mechanisms 63. The support frame 61 is connected to the front side wall assembly 110 and the rear side wall assembly 100, and is located at the side of the vehicle body shell 20 away from the rocker 43. The four arms 65 are all rotatably connected to the support frame 61, and each group of rotor mechanisms 63 is arranged in one-to-one correspondence on one arm 65.

[0023] Please refer to Figure 1 and Figure 2The support frame 61 can adopt a hollow frame structure, which is generally in the shape of a square frame. The support frame 61 is arranged along the first direction X. The specific direction of the first direction X is not limited in the application. For example, the first direction X can be the length direction of the vehicle body shell 20 of the flying car 200, or the width direction of the vehicle body shell 20 of the flying car 200. In the embodiment, the first direction X is the length direction of the vehicle body shell 20 of the flying car 200. The four arms 65 are respectively connected to the four corners of the support frame 61.

[0024] In the embodiment, the rotor mechanism 63 is four groups, and the four groups of rotor mechanisms 63 are arranged one by one on the four arms 65 to provide lifting force for the flying car 200 through the arms 65 and the support frame 61. Each group of rotor mechanisms 63 includes two rotor assemblies 632 connected to opposite sides of the corresponding arm 65. The rotor assembly 632 includes a motor connected to the arm 65 and a propeller connected to the output shaft of the driving motor, and the driving motor is used to drive the propeller to rotate. The output shafts of the two motors on the same arm 65 are coaxial, and the two corresponding propellers of the two motors are also coaxial, thereby forming a four-axis eight-propeller flight module.

[0025] The front side wall assembly 110 is connected to one end of the frame 41 near the front of the flying car 200. The number of front side wall assemblies 110 is two, and the two front side wall assemblies 110 are arranged on the two sides of the flying car 200 and are approximately symmetrically arranged with respect to the center line of the width direction of the flying car 200. The front side wall assembly 110 is connected to the rear side wall assembly 100 through the rocker 43. In some embodiments, the rocker 43, the front side wall assembly 110, and the rear side wall assembly 100 can be integrally formed to improve the stability of the vehicle body structure of the flying car 200.

[0026] In the embodiment, the rear side wall assembly 100 is connected to one end of the frame 41 near the tail of the flying car 200. The number of rear side wall assemblies 100 is two, and the two rear side wall assemblies 100 are arranged on the two sides of the flying car 200 and are arranged one by one with the two front side wall assemblies 110. The structures of the two rear side wall assemblies 100 are approximately the same, and the rear side wall assembly 100 on the left side of the vehicle body of the flying car 200 is taken as an example for description in the embodiment.

[0027] Please refer to Figure 1 and Figure 3The rear quarter assembly 100 provided by the present application comprises a rear quarter body 10 connected to the rocker 43. In the embodiment, the rear quarter body 10 can comprise a cabin portion 12 and an arm mounting portion 14 connected in sequence along the first direction X according to the application function. The cabin portion 12 is connected to the rocker 43 and is used to define the cabin space of the flying car 200. The cabin portion 12 is provided with a wheel avoiding area 121, which is arranged close to the arm mounting portion 14 and at the end of the rocker 43 away from the front quarter assembly 110. The wheel avoiding area 121 is used to mount the wheels (for example, rear wheels) of the land system 80.

[0028] Please also refer to Figure 3 and Figure 4 In order to promote the lightweight of the flying car 200, the cabin portion 12 is provided with a weight reduction hole 123, which penetrates the cabin portion 12 along the second direction Y. The second direction Y intersects (for example, perpendicular to) the first direction X, and the second direction Y is the width direction of the body shell 20 of the flying car 200 (as shown in Figure 1 The weight reduction hole 123 can also be used to form a porthole, for example, to mount glass.

[0029] The arm mounting portion 14 is connected to one side of the cabin portion 12 close to the tail of the flying car 200 and adjacent to the wheel avoiding area 121. The arm mounting portion 14 is bent relative to the cabin portion 12 and extends towards the direction away from the wheel avoiding area 121. The arm mounting portion 14 visually extends along the length direction of the flying car 100, making the flying car 100 look more harmonious as a whole. In order to mount the flight system 60 on the arm mounting portion 14, the connecting end of the arm mounting portion 14 needs to reach the mounting height of the flight system 60. The arm mounting portion 14 is bent and extends towards the direction away from the wheel avoiding area 121, without the need to increase the material, simplifying the structure and promoting the lightweight of the flying car 200. The flight system 60 is arranged on the rear quarter assembly 100 through the arm mounting portion 14, which improves the body strength of the flying car 200 and improves the stability of the flight system 60.

[0030] Further, the dimension of the arm mounting portion 14 along the third direction Z is smaller than the dimension of the cabin portion 12 along the third direction Z. The third direction Z intersects with the first direction X and the second direction Y (for example, perpendicular to each other), and the third direction Z is the height direction of the vehicle body shell 20 of the flying car 200. In terms of the dimension or distance along the third direction Z, the distance between the end of the arm mounting portion 14 away from the cabin portion 12 and the rocker 43 is greater than the distance between the end of the arm mounting portion 14 close to the cabin portion 12 and the rocker 43. It can also be considered that, in the parked state, the distance between the front end of the arm mounting portion 14 (the end close to the front of the flying car 200) and the ground is smaller than the distance between the rear end of the arm mounting portion 14 and the ground, so that from the outside, the arm mounting portion 14 is approximately in a raised structure, so as to facilitate the installation of the flight system 60. The support frame 61 is connected to the end of the arm mounting portion 14 away from the cabin portion 12 close to the tail of the flying car 200, and the end of the support frame 61 close to the head of the flying car 200 is connected to the front side wall assembly 110. The flight system 60 is arranged on the rear side wall assembly 100, which improves the strength of the vehicle body of the flying car 200, and improves the stability of the flight system 60.

[0031] In order to facilitate the lightweight of the rear side wall assembly 100, the arm mounting portion 14 is provided with a cavity 141, and in order to ensure the structural strength of the arm mounting portion 14, the rear side wall assembly 100 further comprises a rear side wall support 143, which is arranged in the cavity 141 and can be fixed to the inner wall of the cavity 141 by structural adhesive. The middle part of the rear side wall support 143 is arched to form a cavity, which improves the rigidity of the structure while ensuring the lightweight of the structure. The profiles of the two sides of the support 143 and the inner wall of the cavity 141 match, and the two are fitted to improve the support strength. The specific material of the rear side wall support 143 is not limited in the present specification, for example, the rear side wall support 143 can be made of aluminum or steel.

[0032] In the embodiment, the rear side wall assembly 100 further comprises a mounting joint 30 for connecting the support frame 61 and the arm mounting portion 14.

Specifically, the mounting joint 30 comprises a mounting portion 32 and an embedding portion 34, the embedding portion 34 is embedded in the cavity 141 and connected with the arm mounting portion 14. The connection between the embedding portion 34 and the arm mounting portion 14 can be glue joint, screw joint, rivet joint or mixed design. The embedding portion 34 is substantially in the shape of a cylinder with both ends passing through, and the cross section is substantially rectangular, and the axis of the embedding portion 34 is substantially parallel to the third direction Z. The mounting portion 32 is connected to the end of the embedding portion 34 away from the wheel avoidance area 121 and located outside the cavity 141, and the mounting portion 32 is substantially in the shape of a plate. The mounting portion 32 is used to bear and connect the support frame 61, and the thickness of the mounting portion 32 is greater than the wall thickness of the embedding portion 34. In the embodiment, the thickness of the mounting portion 32 is 5 mm, and the wall thickness of the embedding portion 34 is 3.5 mm.

[0033] The specific material of the mounting joint 30 is not limited in the specification, for example, the mounting joint 30 can be made of steel plate, or can be made of 7 series aluminum alloy material, and in the embodiment, the mounting joint 30 is made of 7 series aluminum alloy material. The high-strength 7 series aluminum alloy material and the structural design of the mounting joint 30 with variable thickness make the rear side wall assembly 100 achieve the purpose of weight reduction while meeting the high-strength requirement of the key connection point of the rear side wall assembly 100 and the flight system 60.

[0034] In the embodiment, from the assembly structure, the rear side wall main body 10 can comprise a rear side wall inner plate 16 and a rear side wall reinforcing plate 18, the rear side wall inner plate 16 is connected to the rear side wall reinforcing plate 18 and arranged in a buckling manner with the rear side wall reinforcing plate 18 to form the cabin portion 12 and the arm mounting portion 14 together. The materials of the rear side wall inner plate 16 and the rear side wall reinforcing plate 18 can be CFRP material (fiber reinforced composite material), aluminum plate or steel plate, and in the embodiment, the rear side wall inner plate 16 and the rear side wall reinforcing plate 18 are made of CFRP material. CFRP material is a composite material formed by taking carbon fiber or carbon fiber fabric as reinforcement and taking resin, ceramic, metal, cement, carbon or rubber as matrix, and has higher specific strength and specific rigidity among many lightweight materials, and the lightweight effect is very obvious. The rear side wall inner plate 16 and the rear side wall reinforcing plate 18 are mainly connected by structural glue to form the structure and load-bearing main body of the rear side wall assembly 100.

[0035] The rear side wall inner plate 16 comprises a first main body portion 161, and the rear side wall reinforcing plate 18 comprises a second main body portion 181. The first main body portion 161 and the second main body portion 181 are opposite to each other along the second direction Y and are connected to each other. When the rear side wall inner plate 16 and the rear side wall reinforcing plate 18 are buckled to each other, the first main body portion 161 and the second main body portion 181 jointly form the vehicle cabin portion 12, and the wheel-avoiding area 121 is formed on the same side of the first main body portion 161 and the second main body portion 181.

The rocker reinforcing member 50 is fixedly connected to the connecting flange 1623 and is located between the first main body portion 161 and the second main body portion 181. The rocker reinforcing member 50 and the rocker 43 are respectively located on the opposite sides of the connecting flange 1623, and the rocker reinforcing member 50 reinforces the connection strength between the connecting flange 1623 and the rocker 43. The rocker reinforcing member 50 comprises a first shell 52 and a first reinforcing rib 54. The first shell 52 has an inner cavity 521 penetrating through both ends of the first shell 52 along the first direction X, so that the first shell 52 is substantially a cylinder with both ends penetrating through. The first shell 52 is fixed to the connecting flange 1623. The first reinforcing rib 54 is arranged in the inner cavity 521 of the first shell 52. The number of the first reinforcing rib 54 is multiple, and the multiple first reinforcing ribs 54 are arranged staggered in the inner cavity 521 to divide the inner cavity 521 into multiple reinforcing cavities 56. The first reinforcing rib 54 is substantially a plate to jointly form the reinforcing cavity 56 with the side wall of the adjacent inner cavity 521. Therefore, the first reinforcing rib 54 is arranged in the inner cavity 521 to improve the strength, rigidity and impact resistance of the rocker 43, and the structure is simple and the cost is low.

[0038] The connection between the first shell 52, the connecting flange 1623 and the rocker 43 is not limited in the specification, and the connection between the first shell 52, the connecting flange 1623 and the rocker 43 can be adhesive connection, screw connection, rivet connection or a combination of the above. The rocker reinforcement 50 can be made of aluminum profile or steel plate. In this embodiment, the rocker reinforcement 50 is made of 6-series aluminum profile, and the thickness of the first shell 52 of the rocker reinforcement 50 is 2 mm.
