Description

Technical Field

[0001] This invention belongs to the field of flying car technology, and more specifically, relates to a flying car with variable wings. Background Technology

[0002] The government is now strongly advocating for new energy vehicles and the development of the low-altitude economy. New energy vehicles are developing rapidly and have gradually become popular, but they have also led to increasingly congested traffic. Many car companies are responding to the national call and are actively developing flying cars, which have both low-altitude flight and land travel functions.

[0003] Currently, there are two main types of flying cars: one is the highly convenient vertical takeoff and landing (VTOL) multi-rotor system, which boasts excellent maneuverability and flexibility, making it suitable for most terrains. However, it relies entirely on high-speed rotor motion to overcome gravity, resulting in very high energy consumption and short flight time, limiting its application to short distances and small areas. The other type is the fixed-wing flying car, whose wings generate low-energy lift during flight, offering high speed, long range, and extended flight time during level flight. However, it requires specific runways, significantly limiting its practical applications. There is also a type of flying car that combines VTOL with fixed wings. While it possesses the advantages of the two types mentioned above, it generates drag and turbulence during flight, making it unsuitable for use on public roads. Some existing flying cars have incorporated foldable wings to make them suitable for road use, but the foldable wing mechanism compromises safety and has an unattractive appearance.

[0004] Some aircraft with rotating wings are called autogyros. They use a rotor blade at the tail as the forward thrust. During takeoff or landing, they rely on the airflow blowing in front to keep the top wing in a state of rotation, generating stable lift. Even if the rotor blade stops working due to loss of power, they can still land safely by relying on the top autogyro. Although autogyros have good low-altitude safe flight performance, autogyros or helicopters with a long autogyro fixed on the top are very inconvenient to move or park on land.

[0057] The following disclosure provides many different implementations or examples for different ways of implementing the present invention.

[0058] Reference Figures 1 to 20 As shown, a variable-wing flying car is provided, including a body 100 and a steerable wing 200 movably mounted on the body 100. A passenger cabin 120 is provided in the middle of the body 100. The wing 200 is an integral part of the body. A first fixed frame 210 for accommodating the passenger cabin 120 is provided in the middle of the wing 200. A rotating device 300 is connected to the middle of the wing 200 and is connected to the body 100.

[0059] When the flying car is driving on land, the wing 200 can be rotated to be placed parallel to the longitudinal direction of the body 100.

[0060] When the flying car is in the air, the wing 200 can be rotated to a direction perpendicular to the width of the car body 100 to act as a lifting wing.

[0061] In this embodiment, the flying car is a dual-purpose vehicle capable of low-altitude flight and / or land travel. It can be driven by various power sources, including but not limited to electric power for land travel or air flight, and has existing land driving and air flight control technologies.

[0062] Example 1:

[0063] like Figures 1 to 5 As shown in the figure, in this embodiment, please refer to... Figure 1 , Figure 2 As shown, the shape and structure of the vehicle body 100 are similar to those of a traditional sedan, and its land-based configuration is basically the same as that of a new energy vehicle. The vehicle body 100 includes a frame 110, which is fixedly connected (e.g., by welding) to several body longitudinal beams 111 (including roof longitudinal beams 112) and several body transverse beams 113 (including roof transverse beams 114) and several body vertical bars 115. The frame 110 set in this scheme has a greater load-bearing strength than the frame of a car that travels on land alone, because all the weight of a car that travels on land alone is borne downwards on the chassis, while the weight of a flying car in flight is borne upwards through the frame 110.

[0064] A relatively small passenger cabin 120 is located in the middle of the vehicle body 100. The shape is preferably circular, elliptical, or hexagonal, including at least two front A-pillars and two rear B-pillars on both sides. The cabin contains a control panel 150 and a seat 160. The control panel 150 is capable of manual or automatic operation as in existing electric vehicles and flying cars. A low door 140 is located on one side of the passenger cabin 120, which is lower than the location of the rotating device 300, similar to the low door of a sports car. The seat 160 is preferably a height-adjustable seat (not shown in the figure), which makes it easier to lower the seat when entering and exiting, and can be raised to increase comfort during land travel or flight. The vehicle body 1 also includes four wheels 130 and a main battery pack 190 at the bottom of the passenger cabin 120.

[0065] As a preferred embodiment of the present invention, please refer to Figure 3As shown, the wing 200 includes a central first fixed frame 210, which is integrally formed from a circular plate. The inner diameter of the first fixed frame 210 is larger than the outer perimeter of the cockpit 120, allowing it to rotate around the cockpit 120. The wing spars 220 include a front wing spars and a rear wing spars. The front of the first fixed frame 210 is fixedly connected to the middle section of the front wing spars, and the rear is fixedly connected to the middle section of the rear wing spars. It should be noted that these two wing spars 220 are the most important load-bearing beams and require sturdy solid metal strips or thick steel pipes. The front-to-back spacing between the two wing spars 220 should be larger than the inner diameter of the first fixed frame 210. Several wing ribs 230 are arranged laterally on both sides. The top of the wing ribs 230... The shape is arc-shaped, while the bottom is relatively horizontal. The height of the front part is greater than that of the rear part. The front end is provided with a first through hole 231. The front wing beam passes through each first through hole 231 and is fixedly welded. The rear wing beam is fixedly welded to the rear end of each wing rib 230. The front part of each wing rib 230 is fixedly connected to several block-shaped front longitudinal walls, and the rear part is fixedly connected to several smaller block-shaped rear longitudinal walls. Several support rods 250 are fixedly connected to the top and bottom of all wing ribs 230. The two sides of the first fixed frame 210 are fixedly connected to the wing ribs 230, longitudinal walls 240 (including front and rear longitudinal walls) and support rods 250 to form a stable frame structure. A layer of metal skin 260 is fixedly covered on the upper and lower surfaces of the frame structure.

[0066] As a preferred embodiment of the present invention, please refer to Figure 4 , Figure 5 As shown, the rotating device 300 includes an annular slider 310; the outer diameter of the annular slider 310 is provided with a slider gear 311, and the inner diameter is provided with several (e.g., four) inwardly extending protrusions 312, the protrusions 312 are fixedly connected to an upwardly extending connecting block 313, and the connecting block 313 is fixedly connected to the first fixed frame 210 of the wing 200 and / or the middle section of the front wing spars and rear wing spars; the annular slider 310 is movably disposed inside the annular slide groove 320; the inner diameter of the annular slide groove 320 is larger than the outer perimeter of the cockpit 120, and the whole is a hollow annular shape, with a cross-section of a U-shaped structure or a C-shaped structure with the opening facing inward, and the height of the opening is smaller than that of the annular slider 310. The thickness is greater than that of the protrusion 312. The interior of the annular slide groove 320 is adapted to accommodate the annular slider 310. The top and / or bottom of the annular slide groove 320 can be further provided with an annular guide rail 322 (or small roller). The annular slide groove 320 has a small slide groove notch 321 on the outside. The slide groove notch 321 can enable part of the slider gear 311 to mesh with the first gear 331 driven by the first motor 330. The bottom of the annular slide groove 320 is fixedly connected to the longitudinal beam 111 and / or cross beam 113 of the frame 110 around the driver's cabin 120. The wing 200 on the top is fixedly connected by the connecting block 313, the protrusion 312 and the annular slider 310.

[0067] As a preferred embodiment of the present invention, please refer to [the relevant documentation]. Figure 1 , Figure 2 As shown, this embodiment is preferably configured as a relatively small and lightweight flying car. A small cockpit is set in the middle of the body 110, which contains a control panel 150 and only accommodates one seat 160. At least one upward propulsion power device 400 is fixedly installed in the body 100 in front of and behind the cockpit 120. It is preferably a rotor mechanism 410 that can generate upward lift, including a rotor blade 411, a second motor 412, and a shaft 413; a shell 414, a support rod 415, and a circular frame 416; the support rod 415 is configured as two rods, one horizontal and one vertical. The two ends of the horizontal rod are fixedly connected to two vertical rods 115 on both sides of the width direction of the body 100, and the two ends of the vertical rod are fixedly connected to the front and rear vertical rods 115 on both sides of the length direction of the body 100, forming a cross shape. The rotor 410 is fixedly connected to the shell 414. Preferably, two sets of rotor mechanisms 410 are arranged vertically, with the upper and lower rotor blades 411 rotating in opposite directions. The upper and lower shells 414 can be fixedly connected separately or formed as a single unit. A circular frame 416 is provided around the rotor blades 411 to protect them and improve overall stability and safety. The bottom of the body 110 is not provided with a floor plate, and the top is not provided with a cover plate. However, multiple longitudinal beams 111 and transverse beams 113 can be provided at the upper and lower positions of the rotor mechanism 410 and connected to each other (not shown in the figure). This can not only make the fuselage structure stable, but also ensure that the airflow is not affected during flight. When it is needed to travel on land, the wing 200 is rotated 90 degrees and placed longitudinally on the body 100, becoming the front and rear covers (front engine cover and rear trunk cover) lower than the cockpit 120. Figure 2 ).

[0068] A forward-propulsion power unit 400, designated as a culvert fan 420, is vertically installed at the rear of the vehicle. It consists of fan blades 421, a third motor 422, and a culvert tube 423. The culvert tube 423 is fixedly connected to the longitudinal beams 111 and the transverse beams 113 of the rear frame 110 of the vehicle body 100. Alternatively, an additional culvert fan 420 can be installed at the front of the vehicle to increase horizontal propulsion power. This is because it can be used after the rotor device 410 inside the vehicle body 110 stops during level flight cruising, thus avoiding mutual interference with airflow.

[0069] Operating principle of Example 1: When the flying car needs to drive on land, since its land-driving configuration is basically the same as that of a new energy electric vehicle, it can be used in the same way as an electric vehicle. The wings 200 are longitudinally covered on the body 100, forming front and rear covers that are lower than the passenger cabin 120, which also protect and cover the internal rotor mechanism 410, forming an electric vehicle that drives on land.

[0070] When a flying car needs to fly in the air, when it is used for short-distance and small-scale applications, after rotating the wing 200, the rotor mechanism 410 in front of and behind the vehicle body is exposed. The required lift can be provided by the vertically takeoff and landing upward propulsion power device 400, forming a multi-rotor flying car with vertical takeoff and landing. The propulsion power device 400 also includes other power devices (such as jet engines). If horizontal flight is required using the lift provided by the wing 200 for long-distance cruise flight, it can take off or land without a runway, and it is also very energy-efficient, safe, and comfortable. First, control the rotating device 300 to drive the wing 200 to rotate 90 degrees in the longitudinal state to the transverse state and fix it. At this time, the two ends of the wing 200 are horizontally placed in the width direction facing the vehicle body 100, forming a cross shape perpendicular to the vehicle body 100. The rotor mechanism 410 in the vehicle body in front of and behind the driver's cab 12 is not obstructed by the airflow. Further, control the rotating propeller 411 on the rotor mechanism 410 to rotate at high speed. After the flying car is propelled upward to a suitable height, control the opening of the culvert fan 420 at the rear of the vehicle to propel forward. During the forward movement, due to the asymmetric structure of the upper and lower parts of the wing, different airflow pressures are formed, enabling the wing during movement to have a lifting function. After the generated lift can support all the weights of the flying car and the occupants, close the rotating propeller on the rotor mechanism 410 to stop the rotational movement, and then enter a stable horizontal cruise state, which is very energy-efficient and safe. When preparing to land, after decelerating the horizontal flight to a suitable speed, the lift generated by the wing 200 cannot offset all the downward gravity. Control the rotating propeller 411 on the rotor mechanism 410 to rotate again to assist the wing 200 to provide upward lift. When the forward horizontal speed of the flying car decelerates and approaches zero, all the lifting power at this time is provided by the rotor mechanism 410. Close the culvert fan 420 to stop operating, and slowly vertically land on the ground under the control of the rotor mechanism 410. Further, control the rotating device 300 again to drive the wing 200 to rotate 90 degrees in the transverse state to the longitudinal state, forming covers in front of and behind the vehicle body, and then it can be stopped from use or used for land travel.

[0071] Embodiment 2:

[0072] Referring to Figures 6 to 8 As shown, the difference between this embodiment and Embodiment 1 is that the middle of the wing 200 is set to a "ji" - shaped structure, and the rotating device 300 is arranged on the top surface of the driver's cab 120. In this way, the door 140 on the vehicle body 100 can be set relatively high, which is more convenient for entering and exiting the driver's cab 120. The two front and rear culvert fans 420 are set to be telescopic and can turn to upward power, so that the vehicle body 100 of the flying car can be set slightly larger as a whole, which is more convenient and comfortable.

[0073] As a preferred embodiment of the present invention, the passenger cabin 120 includes the first two A pillars 116 and the last two B pillars 117 on both sides. At the top, two roof longitudinal beams 112 and two roof cross beams 114 are fixedly connected respectively, forming a stable framework. The bottom of the circular chute 320 of the rotating device 300 is fixedly connected to the roof longitudinal beam 112 or the roof cross beam 114 on the top surface of the passenger cabin 120. The wing 200 is fixedly connected through the connecting block 313, the bump 312 and the annular slider 310.

[0074] According to the shape of the passenger cabin, the front spar and the rear spar of the wing 200 are set as a "Ji" shape with the middle part extending upward. The first fixing frame 210 is at the bottom of the "Ji" shape and is set as two arc frames that are not connected front and back (if it is a single door, it can be set as not connected on one side). The interval space between the two arc frames is larger than the periphery of the passenger cabin 120, and each is fixedly connected to one side of the wing rib 230, the longitudinal wall 240, the strut 250, as well as the front spar and the rear spar. It should be noted that the first fixing frame 210 in this embodiment can also be in various forms. For example, it can be directly formed into a square frame or a polygon frame that is not connected front and back by using wing ribs 230 or struts or plates, as long as the formed frame is larger than the periphery of the passenger cabin 120, and the unconnected positions can facilitate the entry and exit of the door 140 during land travel or parking. Preferably, it is two non-connected and symmetrical arc frames, which are more suitable for the rotation of the wing 200 relative to the passenger cabin 120.

[0075] The second fixing frame 211 is set as an integral circular frame on the top surface of the "Ji" shape. The inner diameter of the second fixing frame 211 can be set to be smaller than the top surface of the passenger cabin 120. Preferably, it is close to the top area of the passenger cabin 120 for better stability. The height of the interval distance between the passenger cabin 120 and the first fixing frame 210 is set according to the height of the passenger cabin 120. It is fixedly connected to the middle section of the front spar at the front and the middle section of the rear spar at the back. On both sides of the circular frame of the second fixing frame 211, several struts 250 are connected respectively, so that the circular frame is fixedly connected to several surrounding struts, the front spar and the rear spar to form an integral body. There are no connecting fittings between the front and rear arc frames of the first fixing frame 210 and the circular frame of the second fixing frame 211, forming a window-like framework, so that it will not affect the front and rear vision during land travel. The whole wing 200 also does not occupy the space at the door 140 during land travel (such as Figure 7 ).

[0076] As a preferred embodiment of the present invention, this embodiment is different from the foregoing embodiments in that, further, the "ji" - shaped structure provided in the middle of the wing 200 is set as a foldable wing 200. Specifically, the front spar and the rear spar are each set as multi - section spars. The length of the first section of the spar on both sides, on one side, is the distance between the front edge of the cockpit 120 and the front of the vehicle body, and on the other side, is the distance between the rear edge of the cockpit 120 and the rear of the vehicle body. The length of the second section of the spar on both sides is the distance between the front - and - rear top body longitudinal beams 111 and the roof longitudinal beam 112 of the cockpit 120. The length of the middle section is greater than or equal to the length of the roof longitudinal beam 112 of the cockpit 120. One end of the second - section spar is hinged to the first - section spar via a first rotating shaft 221, and the other end is hinged to the middle - section spar via a second rotating shaft 222. The first - section spar and the middle - section spar are each fixedly connected to a first telescopic mechanism 500. The second - section spar is fixedly connected to a second hollow tube, which can be adaptively inserted with the second screw rods on both sides and can be folded manually, or the rotating shafts are configured with motors for driving.

[0077] As a preferred embodiment of the present invention, multiple small battery packs are fixedly added on both sides of the first fixed frame 210 of the wing 200 to assist the main battery pack 190 in increasing power resources. The method is to change the front longitudinal wall at the interval position between the two wing ribs 230 into two upper - and - lower struts. The space in the middle can fix relatively small small battery packs. They are attached to the opposite sides of the two wing ribs 230, with the front side close to the front spar and the rear side against the side of the rear longitudinal wall.

[0078] As a preferred embodiment of the present invention, a telescopic and rotatable culvert fan 420 is further provided at the rear and front of the vehicle body; the culvert fan 420 is composed of a fan blade 421, a third motor 422, and a culvert tube 423; the culvert tube 423 is connected to the first telescopic mechanism 500 via a rotating mechanism 700, and the first telescopic mechanism 500 is fixedly connected to the longitudinal beam 111, the cross - beam 113, and the relevant vertical rod 115 at the front or rear of the vehicle body. Such a setting can flexibly and significantly increase the vertical lift during takeoff. The rotating mechanism 700 and the first telescopic mechanism 500 will be described in detail in other subsequent embodiments and will not be elaborated here.

[0079] Embodiment 3:

[0080] Please refer to Figure 9 、 Figure 10 、 Figure 11As shown, this embodiment differs from Embodiment 1 in that multiple (e.g., four) second telescopic mechanisms are added between the rotating device 300 and the frame 110. The column is located around the perimeter of the passenger compartment 120, preferably fixedly installed on the outside of the two front A-pillars 116 and the two rear B-pillars 117, and fixedly connected to the chassis or related longitudinal beams 111 and cross beams 113 and related vertical rods 115. In this way, the doors 140 on the vehicle body 100 can be set relatively high, making it more flexible and convenient to enter and exit the passenger compartment 120.

[0081] In a preferred embodiment of the present invention, the second telescopic mechanism has the same structure as the first telescopic mechanism 500. The second telescopic mechanism includes a screw rod 510, a nut sleeve 520, a second gear 521, a fourth motor 530, a third gear 531, and hollow columns 540; it is composed of a through groove 541, a receiving groove 542, and a first notch 543. Specifically, the four hollow columns 540 are vertically fixedly connected to two corresponding A columns and two B columns or / and the side crossbeams or longitudinal beams on the chassis. The internal through grooves 541 with upward openings are provided to accommodate the screw rod 510. A notch is opened in the upper middle part of the hollow column 540. The receiving groove 542 can accommodate the device nut sleeve 520 and the second gear 521 fixedly connected to it. The nut sleeve 520 has a nut inside that meshes with the screw rod 510, and can rotate the second gear 521 in the sliding groove (not shown in the figure) inside the receiving groove 542. The receiving groove 542 has a first notch 543 leading to the outside of the hollow column 540. A part of the gear of the second gear 521 is exposed in the first notch 543. The third gear 531 connected to the fourth motor 530 can mesh and rotate. The top end of the screw rod 510 is fixedly connected to the bottom of the annular sliding groove 320 on the rotating device 300.

[0082] In a preferred embodiment of the present invention, a tail wing device 600 is added to the rear of the vehicle body 100; it includes a top horizontal plate 610, vertical plates 620 are fixedly connected to both sides of the bottom surface of the horizontal plate 610, and support rods 630 are fixedly connected to both sides of the bottom inner side of the vertical plates 620; the support rods 630 are connected to the screw ends of the second telescopic mechanism, and the second telescopic mechanism is fixedly placed on the longitudinal beams 111 on both sides of the rear of the vehicle body 100; in this embodiment, a rotor mechanism 410 is fixedly mounted on the tail wing device 600, the rotor 411 faces the rear of the vehicle, the second motor 412 is connected to the rotor 411 via a shaft 413 inside the housing 414, the housing 414 extends upward and is fixedly connected to the middle of the bottom surface of the horizontal plate 610, the two ends of the support rod 415 are fixedly connected to the inner sides of the middle of the vertical plates 620, and the middle of the support rod 415 is fixedly connected to the housing 414.

[0083] The advantage of this embodiment is that the door 140 can be set relatively high, and the raising and lowering of the wing 200 can be flexibly controlled when entering or exiting the passenger cabin 120. This not only facilitates entry and exit, but also allows the second telescopic mechanism to raise the wing 200 without being restricted by side space when driving on land (such as during traffic jams) or parking. The front and rear rotor mechanisms 410 of the passenger cabin 120 are not obstructed by airflow and do not need to turn the wing 200. When the wing 200 is parallel to the body 100, it can also take off or land vertically on the spot. The added tail wing device 600 can make the ride more stable during horizontal cruising.

[0084] Example 4:

[0085] Please refer to Figures 12 to 14 As shown, this embodiment differs from Embodiment 1 in that the flying car is configured as an autogyro or a small helicopter. The bottom of the rotating device 300 is fixedly connected to the top of the screw rods of the four third telescopic mechanisms. This connection and lifting configuration allows the wing 200 to be raised relatively high, suitable for autogyro operation. The connecting block 313 connects to a first fixing frame 210 of an asymmetrical wing 200. The wing 200 is configured such that one side of the wing structure is forward-facing, and the other side is reverse-facing (e.g., ...). Figure 12 The middle wing spars 220 are set to be arc-shaped and fixedly connected to the first fixed frame 210, so that the width of the asymmetrical wing 200 can be set to be smaller than the diameter of the fixed frame 210.

[0086] Furthermore, each side of the wing 200 is configured as a horizontally rotatable and foldable wing, which, when folded, occupies only the top surface space in front of and behind the vehicle body 100. When rotated and unfolded, it forms a longer wing. The front and rear wing spars 220 on opposite sides of the two wings that need to be connected are lengthened and each is fixedly connected to a lateral support rod at the tail end. The upper and lower wing spars 220 are movably connected via a rotation locking mechanism 270, the structure of which is a disc 271 and a matching annular groove 272 (see reference). Figure 4 Each wing beam 220 is fixedly connected to one side. The disc 271 has two first receiving slots 273 with openings in opposite directions. A fourth telescopic mechanism is built in, which has the same structure as the first telescopic mechanism 500. A hollow tube 274 is set on each side of the wing 200 to be connected. The hollow tube 274 is fixedly connected to the wing beam 220. The hollow part of the hollow tube 274 is aligned with a first through hole 231 of the wing rib 230. Multiple small rings 280 can be set at the relatively overlapping positions around the locking mechanism 270. They can be reinforced by using pins or hooks.

[0087] In a preferred embodiment of the present invention, the bottom of the rotating device 300 is fixedly connected to the top end of a cylindrical screw rod of a third telescopic mechanism. The third telescopic mechanism has the same structure as the first telescopic mechanism 500. The bottom of the cylindrical hollow column 540 is fixedly connected to the chassis frame, and the top is connected to the roof frame (e.g., Figure 14 This configuration allows the wing 200 to be raised relatively high, suitable for rotorcraft operation. The opening of the through slot 541 faces the roof surface of the vehicle body 100. The hollow column can be placed in the middle of the interval between two seats or on the rear side of a single seat. Alternatively, multiple hollow columns can be connected to the bottom of the rotating device 300 for greater stability. It should be noted that when configured as an autogyro, the rotating device 300 does not include the slider gear 311, the first gear 331, or the first motor 330. A large bearing 340 is spaced between the annular slider 310 and the annular groove 320. Figure 12 To reduce the coefficient of friction when rotating in the wind and utilize the lift generated by rotation, when operating as a small helicopter, a second annular slider with a slightly smaller diameter and a slider gear 311 is fixedly superimposed on the bottom of the annular slider 310 with bearing 340. The slider gear 311 meshes with at least one first gear 331 and a high-power first motor 330. This arrangement can be further improved by setting a first telescopic mechanism 500 between the first motor 330 and the frame 110 and fixing it to the frame 110. The screw rod 510 is fixedly connected to the first motor 330, thus forming a clutch. When the autogyro starts to run, it can extend into the gear to mesh and generate pre-rotation power, and then retract to form a lift surface for rotating in the wind.

[0088] This asymmetrical wing 200 can be configured as a fixed, one-piece wing in a Z-shape (e.g., Figure 6 (The shape) can also be set as a foldable wing that can hang downwards, such as Figure 14 Structural reference Figure 8 .

[0089] Example 5:

[0090] Please refer to Figures 15 to 17 As shown, the difference between this embodiment and Embodiment 1 is that the flying car is larger and can carry more people (e.g., two people, with a door on each side and seats staggered slightly). Therefore, the power configuration and wing lift need to be increased accordingly.

[0091] In a preferred embodiment of the present invention, two upward propulsion power devices 400 are movably arranged in the front and rear interiors of the passenger compartment 120 of the vehicle body 100. These devices can rotate and fold away from the vehicle body to both sides. Preferably, they are two rotor mechanisms 410 that can generate upward lift, including two rotating propellers 411 arranged vertically and vertically opposite each other, and a second motor 412 connecting the two rotating propellers 411 via a rotating shaft 413. They share a common housing 414. Support rods 415 are arranged in two longitudinal and transverse directions. The housing 414 is fixedly connected in the middle of the support rods 415, and circular frames 416 are fixedly connected to both ends of the support rods 415.

[0092] The rotating mechanism 700 is a fixed connection between the bottom of the fixed block 710 and the chassis and / or side of the longitudinal beam 111, as shown in the reference. Figure 16 The fixed block 710 and the movable block 720 are movably connected via a small rotating shaft 730. The small rotating shaft 730 is directly connected to the decelerated fifth motor 740 (or the two are connected via meshing gears, not shown in the figure). The movable block 720 has a transverse small through hole 721, and a large through hole 722 at the end of the movable block 720 away from the small rotating shaft 730, which is adapted to insert the large rotating shaft 750. One end of the large rotating shaft 750 has a small gear inside the movable block 720 that meshes with the small gear connected to the sixth motor 760 (not shown in the figure, please refer to the reference figure). The two large rotating shafts 750 on both sides are each connected to two different connecting blocks, one of which is... The upwardly extendable upper connecting block 751 is fixedly connected to the support rod 415 and one end of the circular frame. The other connecting block is the downwardly extendable lower connecting block 752. This arrangement is mainly to allow the rotor mechanisms 410 on both sides to be stacked together to make reasonable use of space when they rotate and fold inward. The longitudinal beams 111 of the frame 110 on both sides are set as multiple frame-like structures. A notch 118 is set next to the position of the movable block 720 to accommodate the movable block 720 that rotates outward. A telescopic mechanism 500 is fixedly installed longitudinally inside the frame. The tail end of the screw rod 510 can be inserted into the through hole 721 to fix and limit the movable block 720.

[0093] In a preferred embodiment of the present invention, auxiliary telescopic wings 800 are provided on both sides of the wing 200; each wing rib 230 between the front longitudinal wall and the rear longitudinal wall is frame-shaped; a large rectangular frame 811 with an outward opening is fixedly provided inside the telescopic wing 800, which can accommodate a large telescopic beam 810 inserted into the telescopic wing 800; a fifth telescopic mechanism is fixedly provided inside the large rectangular frame 811, which is the same as the first telescopic mechanism 500; one end of the large telescopic beam 810 is connected to the screw rod of the fifth telescopic mechanism, and the other end is fixedly connected to the inner side of the wing rib on the telescopic wing 800; for greater stability, a smaller front telescopic beam 820 is also provided that can be inserted into the front rectangular frame 821, which is fixedly connected to the front wing spar 220; and another smaller rear telescopic beam 830 is provided that can be inserted into the rear rectangular frame 831, which is fixedly connected to the rear wing spar.

[0094] In a preferred embodiment of the present invention, a fixed floor may be provided at the front and rear bottom of the passenger compartment 120. Also, similar to existing electric vehicles, a relatively large battery pack may be installed under the front and rear chassis, with the battery pack's length extending beyond the passenger compartment 120 (e.g., ...). Figure 15 Additionally, two types of movable flooring that can be opened or closed can be installed, see reference. Figure 16 As shown, one type is a roll-up plate 170, which includes multiple long plates that are fixedly connected at intervals with rubber to form a movable plate 171. It has protrusions 172 on both sides and can move on guide rails 173 on both sides of the floor. The movable plate 171 can be rolled onto a roller 174 and can be electrically controlled to open or close. The other type is an openable grille 180 on the floor, which includes multiple grilles 181 with first small pivots 182 on both sides and small holes 183 on the side floor. Each grille is hinged to a linkage rod 184. The linkage rod 184 can swing to control the grille 181 to open for air intake and exhaust (similar to louvers). Both types can be electrically controlled to open for ventilation during flight or close to protect the fuselage from foreign objects during land flight.

[0095] Example 6:

[0096] Please refer to Figures 18 to 20 As shown, this embodiment differs from Embodiment 1 in that the flying car is also larger and can carry multiple people (e.g., two people), and the power configuration and wing lift are correspondingly increased.

[0097] In a preferred embodiment of the present invention, two upward propulsion power devices 400 capable of horizontal rotation away from the vehicle body 100 are movably arranged on both sides of the front and rear of the vehicle body 100. These are preferably rotor mechanisms 410 capable of generating upward lift, comprising two vertically opposed rotating propellers 411, connected by a rotating shaft 413 to the two propellers 411. The rotating shaft 413 is connected to a second motor 412, sharing a common housing 414. The housing 414 is connected to one end of the arm 430. The rotating mechanism 700 is a cylindrical fixed block 710 whose bottom is fixedly connected to the chassis or lower longitudinal beam 111, and whose top is fixedly connected to the upper longitudinal beam 111. 11 or the upper crossbeam 113 is fixedly connected, and the sleeve-shaped movable block 720 is movably fitted on the cylindrical fixed block 710. The upper part of the movable block 720 is fixedly connected to the other end of the arm 430, and the lower part is fixedly fitted with the fourth gear 723 to form an integral part. The fifth motor 740 is connected to the fifth gear 741 and the fourth gear 723 for meshing and matching. The two side frames 110 inside the body 100 are provided with accommodating space, and the body sheet outside the accommodating space is not used or is set as an openable movable plate (not shown in the figure). When driving on land, rotating the arm 430 can hide the rotor mechanism 410 inside the two side bodies.

[0098] As a preferred embodiment of the present invention, a simple tail wing device 600 is added to the rear of the vehicle body 100; the upper part of the movable block 720 is fixedly connected to one side of the vertical plate 620, and other configurations and connections are the same as described above. When flying horizontally, the swing of the vertical plate 620 can be controlled to form a rudder.

[0099] In a preferred embodiment of the present invention, two steerable rotor mechanisms 410 are configured inside the front and rear of the passenger compartment 120 of the vehicle body 100, including a rotor blade 411, a second motor 412, and a rotating shaft 413; a housing 414, a support rod 415, and a circular frame 416; unlike embodiment 1, the support rod 415 is only provided as a horizontal line, and each end of the support rod 415 is fixedly connected to a large rotating shaft 750. The large rotating shaft 750 is rotatably disposed in a large through hole 722, which is disposed in a fixed block 710. One end of the large rotating shaft 750 is provided with a small gear in the fixed block 710, which meshes with the small gear connected to the sixth motor 760 (not shown in the figure, but please refer to the reference). Figure 16 The bottom of the fixing block 710 is fixedly connected to the chassis and / or the side to the longitudinal beam 111 (e.g., Figure 18 In this way, the two steerable rotor mechanisms 410 inside the vehicle body 100 can be steered horizontally during takeoff and landing as a vertical power configuration, and steered vertically during level flight and cruise as a forward propulsion power configuration.

[0100] In a preferred embodiment of the present invention, auxiliary folding wings 900 are provided on both sides of the wing 200. At least one torsion spring hinge 911 is provided on the outer side of the last rib 240 on both sides of the wing 200, which is fixedly connected to the rib 910 on the folding wing 900. At least one fixed rod 920 is provided on the outer side of the rib 910, which is movably hinged to the movable rod 921. The movable rod 921 is connected to the internal telescopic mechanism 500 through a through hole (not shown in the figure). In order to make the folding wings 900 more secure and stable during flight, an auxiliary reinforcement telescopic mechanism 500 is provided on each side of the wing 200. Correspondingly, hollow tubes 930 for the insertion of screw rods are provided in the folding wings 900 on both sides. When traveling on land, the wing 200 and the folding wing 900 are stacked together on the front and rear body 100 under the torsional force of the torsion spring hinge 911.

[0101] The various aspects of the embodiments described above can be combined or substituted with each other without mutual exclusion; the flying car is capable of both land driving and low-altitude flight, and can be configured for manual or automatic driving. For greater energy efficiency and safety, the vehicle body needs to utilize more lightweight materials (such as carbon fiber and aluminum alloy). The first fixed frame 210 is wholly or partially fixedly connected to the wings 200 on both sides, and can have various shapes as long as its inner diameter is larger than the outer perimeter of the passenger cabin 120. The second fixed frame 211 is not limited in size and can also have various shapes (such as a small disc). This invention limits the volume of the passenger cabin 120 to allow the wings 200 to rotate, and also limits the vehicle body weight for flight. It is recommended to set a speed limit for safer operation on land. During flight, although the rotating device 300 can automatically lock the rotation angle when stopped, for the wings 200... The wing 200 is perpendicular to the body 100, forming a more stable cross shape. A corresponding through hole is provided at the same position on the annular slider 310 and the circular groove 320 of the rotating device 300. A pin is also provided for manual or electric insertion. Alternatively, a limiting block is provided on the circular groove 320 to limit the rotation angle of the annular slider 310 of the rotating device 300. This ensures the wing 200 is vertically and securely fixed to the body 100 in a stable cross shape, enhancing safety. A sunroof can be provided on the top of the passenger compartment 120, allowing for normal entry and exit through the door 140 and emergency exit through the sunroof. Ejection seats can further enhance safety (these are existing technologies). Limiting blocks or grooves should be provided at all pivot points to prevent disengagement. Additional reinforcement devices can be added to all connecting parts. Auxiliary telescopic wings, folding wings, and multi-section folding wings can also be reinforced with additional devices for greater stability and safety.

[0102] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
