Description

Technical Field

[0001] This invention relates to the field of flying car technology, and in particular to folding-wing flying cars. Background Technology

[0002] Currently, most flying cars are fixed-wing aircraft. However, when the flying car and aircraft are not in flight, the large wings occupy a significant amount of storage space, making storage difficult. When used as a flying car, the large wings also occupy a large amount of road space when the flying car needs to travel on the ground, and current road lanes cannot meet the driving requirements of flying cars.

[0003] Similar folding solutions exist, allowing some wings to be folded to the outside of the fuselage. While this method reduces the volume occupied by the wings to some extent, it still presents two problems: First, folding the wings to the outside of the fuselage results in an excessively large wing and folding mechanism, taking up valuable space in the fuselage's circumference. This excessive size makes it unsuitable for driving on normal roads. Second, folding the wings to the outside of the fuselage, due to the complex structure of the wings and their folding mechanism and their failure to meet aerodynamic requirements, increases drag and reduces driving efficiency when on the road.

[0004] Therefore, there is an urgent need for folding-wing flying cars to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a folding-wing flying car to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following solution: The present invention provides a folding-wing flying car, comprising a fuselage body and a tail fin and two wings mounted on the fuselage body.

[0007] The fuselage body has storage slots on both sides, which are adapted to the wings. The fuselage body has a storage cavity at the rear, which is adapted to the tail fin.

[0008] Two wing storage assemblies are respectively disposed in the two storage slots. Each wing storage assembly includes a flipping component, a rotating component, and a moving component. The moving component is disposed in the storage slot to drive the wing to move along the axial direction of the fuselage body. The rotating component is disposed on the moving component to drive the wing to unfold / fold. The flipping component is disposed on the rotating component and is configured to drive the wing to a horizontal state when the wing is unfolded and to drive the wing to a vertical state when the wing is folded.

[0009] A tail wing storage component is disposed within the storage cavity, and the tail wing is stored in the storage cavity through the tail wing storage component.

[0010] Preferably, the movable component includes a slide rail fixedly connected to the bottom of the storage slot, a slider slidably connected to the slide rail, a rotating component fixedly connected to the slider, and a first motor fixedly connected to one side of the slide rail, the first motor being used to drive the slider to slide on the slide rail.

[0011] Preferably, the rotating component includes a first support frame and a second support frame fixedly connected to the top of the slider. A second motor is fixedly connected to the first support frame. A drive gear is fixedly connected to the output shaft of the second motor via a connecting shaft. A rotating gear is rotatably connected to the second support frame via a rotary bearing. The drive gear meshes with the rotating gear. The flipping component is disposed on the rotating gear.

[0012] Preferably, the flipping component includes a third support frame fixedly connected to the top of the rotating gear, a third motor fixedly connected inside the third support frame via a fourth support frame, and the output shaft of the third motor fixedly connected to the wing via a rotary drive fixture, a coupling, and a wing swivel bearing.

[0013] Preferably, the tail fin storage component includes a plurality of linear bearings fixedly connected to the bottom end of the storage cavity, and the top end of the linear bearings is fixedly connected to the bottom end of the tail fin via a hydraulic actuator.

[0014] Preferably, the tail fin storage component includes a plurality of linear bearings fixedly connected to the bottom end of the storage cavity, and the top end of the linear bearings is hinged to the bottom end of the tail fin via a hydraulic actuator.

[0015] Preferably, the tail fin includes a tail fin fixing plate, and tail fin plates are fixedly connected to both sides of the top of the tail fin fixing plate. The two tail fin plates are fixedly connected by a transverse fin plate. One side of the tail fin plate is hinged to one end of the first transverse fin, and the other end of the first transverse fin is hinged to a second transverse fin.

[0016] Preferably, the top and bottom of the opening of the storage slot are respectively hinged with a first hatch and a second hatch, and the first hatch and the second hatch have a double-door structure.

[0017] Preferably, a third door is slidably connected to the top of the storage cavity.

[0018] Preferably, a plurality of fixed frames are fixedly connected along the axial direction on the wing, and propellers are mounted on the fixed frames.

[0019] Compared with the prior art, the present invention has the following advantages and technical effects:

[0020] The folding-wing flying car provided by this invention, when folding its wings, uses a set-in flipping component to adjust the wings from a horizontal to a vertical position. Then, a set-in moving component moves the wings towards the nose of the fuselage. After the movement is complete, a set-in rotating component rotates the wings to retract them into a storage slot. Simultaneously, the tail fin is retracted into a storage cavity by a set-in tail fin storage component, thus achieving the folding of the wings and tail fin into the fuselage. This invention effectively reduces the volume occupied by the wings and tail fin in the non-flying state and solves the problem of excessive wind resistance when the flying car is driving on the road.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Reference Figures 1-10 The present invention provides a folding-wing flying car, comprising a fuselage body 1, a tail fin 2 and two wings 3 mounted on the fuselage body 1.

[0036] The fuselage body 1 has storage slots on both sides, which are adapted to the wings 3. The fuselage body 1 has a storage cavity at the tail, which is adapted to the tail wing 2.

[0037] Two wing storage components are respectively set in two storage slots. The wing storage components include a flipping component 4, a rotating component 5 and a moving component 6. The moving component 6 is set in the storage slot to drive the wing 3 to move along the axial direction of the fuselage body 1. The rotating component 5 is set on the moving component to drive the wing 3 to unfold / fold. The flipping component 4 is set on the rotating component 5 and is configured to drive the wing 3 to be in a horizontal state when the wing 3 is unfolded and to drive the wing 3 to be in a vertical state when the wing 3 is folded.

[0038] The tail wing storage component 7 is set inside the storage cavity, and the tail wing 2 is stored in the storage cavity through the tail wing storage component 7.

[0039] In a further optimized design, the moving component 6 includes a slide rail 61 fixedly connected to the bottom of the storage slot, a slider 62 slidably connected to the slide rail 61, a rotating component 5 fixedly connected to the slider 62, and a first motor 63 fixedly connected to one side of the slide rail 61. The first motor 63 is used to drive the slider 62 to slide on the slide rail 61.

[0040] Reference Figure 3 A threaded rod can be installed on the slide rail 61. The slider 62 is threadedly connected to the threaded rod. The output shaft of the slider 62 is connected to the threaded rod to drive the threaded rod to rotate. When the threaded rod rotates, it drives the slider 62 to move on the slide rail 61, thereby driving the wing 3 to move along the axis of the fuselage body 1.

[0041] In one embodiment of the present invention, when the wings 3 of the fuselage body 1 are deployed and in flight, the wings 3 are displaced to the middle of the fuselage body 1. When the wings 3 are retracted, the wings 3 are first moved toward the head of the fuselage body 1, and then rotated and retracted.

[0042] In a further optimized design, the rotating component 5 includes a first support frame 51 and a second support frame 52 fixedly connected to the top of the slider 62. A second motor 53 is fixedly connected to the first support frame 51. A drive gear 54 is fixedly connected to the output shaft of the second motor 53 via a connecting shaft. A rotating gear 56 is rotatably connected to the second support frame 52 via a rotating bearing 55. The drive gear 54 meshes with the rotating gear 56. The flipping component 4 is disposed on the rotating gear 56.

[0043] Reference Figure 4 The second motor 53 drives the meshing rotating gear 56 to rotate. When the rotating gear 56 rotates, it drives the wing 3 to be stored in the storage slot. Conversely, it causes the wing to be unfolded and extended out of the storage slot.

[0044] The scheme is further optimized. The flipping component 4 includes a third support frame 41 fixedly connected to the top of the rotating gear 56. A third motor 43 is fixedly connected inside the third support frame 41 through a fourth support frame 42. The output shaft of the third motor 43 is fixedly connected to the wing 3 through a rotary drive tooling 44, a coupling 45 and a wing rotation bearing 46.

[0045] Reference Figure 5 The third motor 43 drives the wing 3 to rotate. When the wing 3 is deployed for flight, the wing 3 is in a horizontal state. When the wing 3 needs to be folded up, the third motor 43 drives the wing 3 to rotate to a vertical state, so that it can be easily folded into the storage slot.

[0046] Further optimization of the design: the tail wing storage component 7 includes several linear bearings 71 fixedly connected to the bottom of the storage cavity, and the top of the linear bearings 71 is fixedly connected to the bottom of the tail wing 2 through a hydraulic actuator 72.

[0047] Reference Figure 7 The hydraulic actuator 72 is fixedly connected to the bottom of the tail fin 2. The tail fin 2 is driven to descend vertically through the linear bearing 71 and the hydraulic actuator 72, and the tail fin 2 is lowered in a straight line and stored in the storage cavity.

[0048] Further optimization of the design: the tail wing storage component 7 includes several linear bearings 71 fixedly connected to the bottom of the storage cavity, and the top of the linear bearings 71 is hinged to the bottom of the tail wing 2 through a hydraulic actuator 72.

[0049] Reference Figure 8 The hydraulic actuator 72 is hinged to the bottom of the tail fin 2. The tail fin 2 is driven to descend vertically and rotate through the linear bearing 71 and the hydraulic actuator 72, so that the tail fin 2 is rotated and stored in the storage cavity.

[0050] The tail wing 2 is further optimized by including a tail wing fixing plate 21. Tail wing plates 22 are fixedly connected to both sides of the top of the tail wing fixing plate 21. The two tail wing plates 22 are fixedly connected to each other by a horizontal wing plate 23. One end of the first horizontal wing 24 is hinged to one side of the tail wing plate 22, and the other end of the first horizontal wing 24 is hinged to a second horizontal wing 25.

[0051] Reference Figure 6 The first wing 24 and the second wing 25 are hinged by a drive hinge and can rotate relative to each other, thereby enabling the first wing 24 and the second wing 25 to be folded. After folding, the tail wing 2 is stored in the storage cavity.

[0052] The design was further optimized so that the top and bottom of the opening of the storage slot are respectively hinged to the first hatch 8 and the second hatch 9, and the first hatch 8 and the second hatch 9 form a double door structure.

[0053] Reference Figure 2 The first door 8 and the second door 9 are both hinged to the open end of the storage slot via drive hinges. When the wing 3 is deployed or retracted, the storage slot is opened by opening the hinged first door 8 and the second door 9.

[0054] The design was further optimized by adding a third hatch 10 that slides at the top of the storage cavity.

[0055] Reference Figure 2 After the tail fin 2 is retracted into the storage cavity, the third hatch 10 slides closed, thus closing the storage cavity.

[0056] Further optimization of the design: several fixed frames 11 are fixedly connected along the axial direction on the wing 3, and propellers 12 are installed on the fixed frames 11.

[0057] Reference Figure 9 The propeller 12 provides power to the flight device.

[0058] Reference Figure 10When the wing 3 is folded, the first door 8 and the second door 9 are opened first. The wing 3 is rotated around its own axis by the set flipping part 4, so that the wing 3 can rotate vertically around the fuselage body 1. At the same time, the moving part 6 moves the wing 3 towards the head of the fuselage body 1. After moving to the head, the wing 3 is folded and stored in the storage slot by the set rotating part 5.

[0059] The folding motion of tail fin 2 can be performed simultaneously. First, the horizontal wings on both sides of tail fin 2 are folded. After folding, tail fin 2 is stored in the storage cavity through the set moving parts. This achieves the folding and storage of tail fin 2 and wing 3.
