Description

Technical Field

[0001] This invention belongs to the field of flying car technology, and more specifically, relates to a flying car with a mother-daughter sleeve. Background Technology

[0002] The government is now strongly advocating for new energy vehicles and the development of the low-altitude economy. Flying cars have both low-altitude flight and land driving functions. Existing integrated flying cars or manned aircraft are very convenient means of transportation. They are equipped with multiple rotor devices that can take off and land vertically, and have good maneuverability and flexibility, making them suitable for use in most places. However, when they need to be driven or stored on land, the multiple exposed rotor devices are not very convenient, and they will increase drag and affect the appearance when driving on land.

[0003] Flying cars or aircraft rely entirely on high-speed rotation of rotors to overcome gravity, resulting in very high energy consumption and short flight times, making them suitable only for short-distance, small-scale use. To address this, some flying cars are equipped with fixed wings on both sides. These wings generate lift with low energy consumption during flight, allowing for high speeds, long ranges, and extended flight times during level flight. Currently, there is a composite wing flying car that combines multiple rotors capable of vertical takeoff and landing with fixed wings. While it possesses the advantages of the two types mentioned above, the multiple exposed rotor devices create drag and turbulence during cruise flight, and also affect driving and appearance when used on public roads.

[0043] The following disclosure provides many different implementations or examples for different ways of implementing the present invention.

[0044] Reference Figures 1 to 11 As shown, a flying car with a mother-daughter sleeve is provided, including a body 100 and a frame 200 disposed on the body 100. The frame 200 is symmetrically arranged on both sides and fixedly connected to a propulsion power unit 400. A retractable mother-daughter sleeve 300 is movably sleeved around the frame 200.

[0045] 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.

[0046] Example 1:

[0047] like Figures 1 to 4 As shown in the figure, in this embodiment, please refer to... Figure 1 , Figure 2 As shown, the vehicle body 100 has a similar overall structure to existing new energy passenger cars and has the control flight function of existing technology. A horizontal frame 200 is fixedly connected to the middle of the top of the vehicle. The frame 200 is an integral structure, which is a rectangular frame body formed by fixedly and cross-connecting at least two longitudinal beams 210 and several transverse beams 220. The propulsion power device 400 is fixedly connected to the inside of both sides and / or the outside of both sides of the frame 200. In this embodiment, the propulsion power device 400 is set as a rotor mechanism 410, including a rotor blade 411, a first motor 412, a rotating shaft 413 and a mounting base 414. The first motor 412 is set in the mounting base 414. The output end of the first motor 412 is connected to the rotating shaft 413 for transmission. The other end of the rotating shaft 413 is fixedly connected to the rotor blade 411. Starting the first motor 412 can drive the rotor blade 411 to rotate, thereby realizing an upward or forward thrust.

[0048] As a preferred embodiment of the present invention, please refer to Figure 2 As shown, the longitudinal beam 210 of the frame 200 is set as a wing beam 211. The cross-section of the wing beam 211 is rectangular, and the whole is a long strip of metal load-bearing beam. Several cross beams 220 are fixedly connected laterally on both sides and in the middle. The cross beams 220 are set as block-shaped wing ribs 221. The top of the wing rib 221 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 wing beam fixedly connected to the front part is higher than the height of the rear wing beam connected to the rear part. The connecting block 250 is fixedly connected in the middle of the frame 200. It is plate-shaped and fixed between the two wing ribs 221 and the wing beam 211. The connecting block 250 is fixedly connected to the roof longitudinal beam and / or roof cross beam of the vehicle body 100 through the connecting hole 251. It can be fixed by bolts (detachable connection) or direct welding.

[0049] As a preferred embodiment of the present invention, please refer to Figure 1 and Figure 2As shown, the propulsion power device 400 inside the frame 200 in this embodiment is configured as a first rotor mechanism 410A, including a rotor blade 411, a first motor 412, a rotating shaft 413, a mounting base 414, support rods 415, and a circular frame 416. The first rotor mechanism 410A is disposed in the internal space on both sides of the frame 200. When placed horizontally, its overall thickness is less than the minimum height of the internal space formed by the wing beam 211 and the wing rib 221. At least two support rods 415 are provided, each end of which is fixedly connected to the inner side of the space formed by the wing beam 211 and the wing rib 221. The support rods intersect to form a cross shape and are fixedly connected to the mounting base 414 in the middle. The second rotor mechanism 410B is disposed on the outer sides of the frame 200, with one symmetrically and vertically arranged on each side to form a forward propulsion power device 400, provided that the mounting base 414 is directly connected to the outer side of the wing rib 221 on both sides.

[0050] As a preferred embodiment of the present invention, please refer to Figure 3 As shown, a mother-daughter sleeve 300 is connected to each side of the frame 200. The mother-daughter sleeve 300 can be composed of at least two cylinders of different shapes and volumes that are integrated into one piece. In this embodiment, it is preferably configured to fit the shape of the wing rib 221. The inner diameter of the inner space of the mother cylinder 310 is larger than the outer diameter of the wing rib 221. One end is fixedly connected to the wing rib 221 and / or the wing beam 211. The edge of the cylinder is fixedly fitted around the outer diameter of the wing rib 221 (sealed with the wing rib). The other end is open and faces away from the vehicle body 100. The daughter cylinder 320 fitted inside is adapted to the mother cylinder 310. The daughter cylinder 320 has the same shape as the mother cylinder 310, but its volume is slightly smaller than that of the mother cylinder 310. The inner diameter of the inner space of the daughter cylinder 320 is also larger than the outer diameter of the wing rib 221. It can be accommodated in the space between the mother cylinder 310 and the frame 200 and can be moved and extended.

[0051] Furthermore, it is preferable to provide several first protrusions 311 inside the mother cylinder 310 and a matching groove 321 on the top surface of the daughter cylinder 320. This allows the daughter cylinder 320 to move stably within the mother cylinder 310 and also provides a limiting function when the daughter cylinder 320 moves. Several small connecting blocks 322 are provided inside the daughter cylinder 320 for connecting the slider 550 on the telescopic mechanism 500.

[0052] Furthermore, it is preferable to set the sub-tube 320 as a movable second mother tube 320, with the second sub-tube 330 adapted inside. The volume of the second sub-tube 330 is smaller than that of the second mother tube 320, and the inner diameter of the internal space is also larger than the outer periphery of the wing rib 221. With the same shape and structure, it can of course also have corresponding protrusions and grooves. Several small connecting blocks 322 are also provided on the inner side of the second sub-tube 330 for connecting the telescopic mechanism 500.

[0053] As a preferred embodiment of the present invention, please refer to Figure 4As shown, the top and / or bottom of the longitudinal beam 210 of the frame 200 are fixedly connected to the telescopic mechanism 500, which includes a fixed frame 510. The fixed frame 510 has an installation space inside. One end of the internal space is equipped with a miniature third motor 520 that can be controlled by a controller (or it can be located externally). The output end of the third motor 520 is connected to a screw rod 530. A slidable slider 550 is also provided in the installation space. The screw rod 530 passes through the nut 540 inside the slider 550 and engages with the thread inside the nut 540. Thus, when the third motor 510 is started, the screw rod 530 rotates, causing the slider 550 to perform a linear reciprocating motion back and forth. When the third motor 510 stops running, the slider 550 can be locked.

[0054] As a preferred embodiment of the present invention, please refer to Figure 1 As shown, a tail wing device 700 is provided at the rear of the vehicle body 100. It is formed by fixing the horizontal plate 710 to the vertical plate 720 on both sides. Two connecting rods 730 are fixedly connected to the vertical plate 720 at one end and to the frame 200 or the rear of the vehicle body 100 at the other end.

[0055] Example 2:

[0056] Reference Figures 5 to 8 As shown, this embodiment differs from Embodiment 1 in that the vehicle body 100 can be further made lightweight and has an internal propulsion power unit 400 configuration. The shape and structure of the flying car are similar to those of a traditional sedan, and the land-based configuration is basically the same as that of a new energy vehicle. The vehicle body 100 includes a frame 110, which consists of several body longitudinal beams 111 (including roof longitudinal beams 112) and several body transverse beams 113 (including roof transverse beams 114), which are fixedly connected to each other (e.g., by welding) with several body pillars 115. The frame 110 set in this solution must have a greater load-bearing strength than the frame of an ordinary 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 the flying car in flight is borne upwards through the frame 110.

[0057] 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 116 and two rear B-pillars 117 on both sides. The cabin contains a control panel 150 and at least one seat 160. The control panel 150 is capable of manual or automatic operation as in existing electric vehicles and flying cars. A low-profile door 140 is located on one side of the passenger cabin 120, below the location of the rotating device 600, similar to the low door of a sports car. The seat 160 is preferably a height-adjustable seat (not shown in the figure; existing technology has adjustable seating posture and convenient entry and exit), so that the seat can be lowered when entering and exiting, and raised to increase comfort during land travel or flight. The vehicle body 100 also includes four wheels 130 and a main battery pack 170 at the bottom of the passenger cabin 120.

[0058] As a preferred embodiment of the present invention, please refer to Figure 5 , Figure 6 As shown, at least one upward propulsion power device 400 is fixedly installed inside the vehicle body 100 at the front and rear of the passenger compartment 120. Preferably, it is a second rotor mechanism 410B capable of generating upward lift, including a rotor 411, a first motor 412, and a shaft 413; a mounting base 414, support rods 415, and a circular frame 416. The support rods 415 are arranged in two parallel and two vertical directions. The two ends of the horizontal rods are fixedly connected to two vehicle body pillars 115 on both sides of the width direction of the vehicle body 100, and the two ends of the vertical rods are fixedly connected to the front and rear vehicle body pillars 115 on both sides of the length direction of the vehicle body 100, forming a cross shape. The middle of the cross shape is fixedly connected to the mounting base 414. Preferably, two sets of second rotor mechanisms 410B are arranged vertically, with the upper and lower rotors 411... 1. It can rotate in opposite directions. The upper and lower mounting seats 414 can be fixedly connected or integrally formed. A circular frame 416 is set around it to protect the rotating propeller 411 and improve the overall stability and safety. The bottom of the body 110 is not provided with a base plate, and the upper part is not provided with a cover plate. However, multiple support rods can be set at the upper and lower positions of the second rotor mechanism 410B. Alternatively, the rod-shaped longitudinal beams 111 and the transverse beams 113 of the body can be connected to each other (not shown in the figure). This can not only make the body structure stable, but also ensure that the airflow is not affected during flight. When it is necessary to travel on land, the frame 200 is rotated 90 degrees and placed longitudinally on the body 100, which becomes the front and rear cover plates lower than the cockpit 120 (like the front engine hood and the trunk lid, such as...). Figure 5 ).

[0059] A forward-propulsion power device 400 is vertically installed at the rear of the vehicle, preferably a culvert fan 420; it consists of fan blades 421, a second motor 422 and a culvert tube 423. The second motor 422 can drive the fan blades 421 to rotate. The culvert tube 423 is fixedly connected to the longitudinal beam 111 and the transverse beam 113 of the vehicle body at the rear of the vehicle body 100. Of course, an additional culvert fan 420 can also be installed at the front of the vehicle to increase the horizontal propulsion power.

[0060] As a preferred embodiment of the present invention, please refer to Figure 6 As shown, the frame 200 is an integral structure. Unlike embodiment 1, it is a rectangular frame formed by at least two long longitudinal beams 210 and several long transverse beams 220 of the same height, which are fixedly and crosswise connected. The top surface of the frame is a horizontal plane. A circular frame 240 is provided in the middle of the frame 200. The circular frame 240 is an integral structure of a ring-shaped plate. The front of the circular frame 240 is fixedly connected to the middle section of the front longitudinal beam, and the rear is fixedly connected to the middle section of the rear longitudinal beam. The inner diameter of the circular frame 240 is larger than the outer perimeter of the passenger compartment 120, and it can be fitted onto the outside of the passenger compartment 120 via the rotating device 600. The frame rotates around the structure. The longitudinal beam 210 has a rectangular cross-section and is a long, strip-shaped metal load-bearing beam. Telescopic mechanisms 500 are fixedly connected to the top and bottom of the longitudinal beam 210. Several horizontal beams 220 are fixedly connected at intervals on both sides and in the middle. The cross-section of the horizontal beams 220 is also rectangular and is a long, strip-shaped metal load-bearing beam. At least one first rotor mechanism 410A is fixedly connected to the internal space of the frame structure formed on both sides. Several rod-shaped longitudinal beams and horizontal beams (not shown in the figure) can also be set on the top and bottom surfaces of the first rotor mechanism 410A, which can both reinforce the frame 200 and not affect the airflow.

[0061] Furthermore, it is preferable to connect and sleeve a mother and daughter sleeve 300 on each side of the frame 200. The mother and daughter sleeve 300 can be composed of cylinders of various shapes and volumes that are integrated. In this embodiment, it is preferable to have a rectangular cross-section or an elliptical cylinder with parallel arcs on both sides, which can be properly fitted on the periphery of the frame 200. Such a mother and daughter sleeve 300 with the same front and rear height on both sides has no lift function, but only serves to protect and cover the first rotor mechanism 410A inside the frame 200. When placed longitudinally with the vehicle body 100, it forms a planar or parallel symmetrical cover plate shape with the same height on both sides.

[0062] The interior of the sleeve 300 forms an accommodating space that can accommodate the rotor mechanism 410. In this embodiment, the sleeve 300 has a rectangular cross-section, which can accommodate the relatively large first rotor mechanism 410A. The rectangular mother sleeve 310 is designed to fit the shape of the crossbeam 220. The inner diameter of the internal space is larger than the outer diameter of the crossbeam 220. One end is fixedly connected to the crossbeam 220 and / or the longitudinal beam 210, and the other end is open, facing away from the vehicle body 100. The daughter sleeve 320, which fits the mother sleeve 310, is fitted inside. The daughter sleeve 320 has the same shape as the mother sleeve 310, but its volume is slightly smaller than that of the mother sleeve 310, and it can be accommodated within the mother sleeve 310. The inner sleeve 300 is located between the outer perimeter of the frame 200 and can be extended and retracted. When the first rotor mechanism 410A inside the frame 200 needs to be used, the extension mechanism 500 is controlled to move the sub-sleeve 320 into the inner sleeve 310, exposing the frame 200 and the rotor mechanism 410, thus generating upward propulsion. When it is needed for land driving or parking, the extension mechanism 500 is controlled to move the sub-sleeve 320 away from the inner sleeve 310, covering the entire frame 200 and the first rotor mechanism 410A. The inner and outer sleeve 300 form a frame-like enclosure that protects the first rotor mechanism 410A, which also forms the shape of the front and rear cover plates of the vehicle body 100.

[0063] As a preferred embodiment of the present invention, please refer to Figure 7 , Figure 8 As shown, the rotating device 600 includes an annular slider 610; the outer diameter of the annular slider 610 is provided with a slider gear 611, and the inner diameter is provided with several (e.g., four) inwardly extending second protrusions 612. The second protrusions 612 are fixedly connected to an upwardly extending connecting rod 613. The connecting rod 613 is fixedly connected to the circular frame 240 of the frame 200 and / or the middle section of the front longitudinal beam and the rear longitudinal beam; the annular slider 610 is movably disposed inside the annular slide groove 620; the inner diameter of the annular slide groove 620 is larger than the outer perimeter of the passenger compartment 120, and the whole is a hollow annular shape with a cross-section of a U-shaped or C-shaped structure with the opening facing inward. The height of the opening is smaller than that of the annular slider 610. The thickness is greater than that of the second protrusion 612. The interior of the annular slide groove 620 is adapted to accommodate the annular slider 610. The top and / or bottom of the annular slide groove 620 can be further provided with an annular guide rail 622 (or small roller). The annular slide groove 620 has a small slide groove notch 621 on the outside. The slide groove notch 621 allows part of the slider gear 611 to mesh with the gear 631 driven by the fourth motor 630. The bottom of the annular slide groove 620 is fixedly connected to the longitudinal beam 111 and / or cross beam 113 of the frame 110 around the driver's cab 120. The frame 200 on the top is fixedly connected to the connecting rod 613, the second protrusion 612 and the annular slider 610.

[0064] Operating principle of Example 2: When the flying car needs to travel on land, since its land-based 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. When the mother-daughter sleeve 300 on the frame 200 is extended, it covers the first rotor mechanism 410A that covers the entire frame 200 and the internal space, and longitudinally covers the body 100, forming front and rear covers that are lower than the passenger cabin 120. It also protects and covers the internal first rotor mechanism 410A, forming the overall form of an electric vehicle that travels on land.

[0065] When the flying car needs to take off, the frame 200 and the body 100 are rotated to form a cross shape, exposing the second rotor mechanism 410B at the front and rear of the body 100. Furthermore, the telescopic mechanism 500 on the frame 200 is controlled to move the sub-cylinder 320 inside the mother cylinder 300 into the mother cylinder 310, or the second sub-cylinder 330 and the sub-cylinder 320 simultaneously move into the mother cylinder 310, exposing the frame 200 and the first rotor mechanism 410A inside. At the same time, multiple first motors 413 are started, causing the second rotor mechanism 410B inside the front and rear of the body 100 and the first rotor mechanism 410A inside the frame 200 to rotate. The required lift can be provided by the vertically take-off and landing upward propulsion power unit 400, forming a multi-rotor flying car that can take off and land vertically.

[0066] Example 3:

[0067] As a preferred embodiment of the present invention, please refer to Figures 9 to 11 As shown, in this embodiment, the frame 200 and the mother-daughter sleeve 300 are preferably further configured as wings with different front and rear thicknesses that have lift.

[0068] The frame 200 includes a central circular frame 240, which is integrally formed from annular plates. The inner diameter of the circular frame 240 is larger than the outer perimeter of the cockpit 120, allowing it to rotate around the cockpit 120. The longitudinal beams 210 are configured as wing beams 211, including columnar front and rear wing beams that bear the main load. The front of the circular frame 240 is fixedly connected to the middle section of the front wing beam, and the rear is fixedly connected to the middle section of the rear wing beam. It should be noted that these two wing beams 211 are the most important load-bearing beams and require sturdy solid metal strips or thick metal pipes. The front-to-back spacing between the two wing beams 211 should be larger than the outer diameter of the circular frame 240. Several transverse beams 220 are arranged at intervals on both sides, forming blocks. The wing ribs 221 are shaped like arcs at the top and relatively horizontal at the bottom. The front part is higher than the rear part. The front end is provided with through holes 2211. The front wing beam passes through each through hole 2211 and is fixedly welded. The rear wing beam is fixedly welded to the rear end of each wing rib 221. The top and bottom surfaces of each wing rib 221 are connected with relatively small longitudinal rods 210. The telescopic mechanism 500 is fixedly connected to the rods 210. Several support rods 230 are also provided around the wing ribs and are fixedly connected to each other to form a stable frame structure with different front and rear heights. Between the two wing ribs 221 on both sides of the frame structure, a relatively wide space is set, and the first rotor mechanism 410A is fixedly connected inside.

[0069] In this embodiment, it is also preferable to further configure multiple smaller first rotor mechanisms 410A (e.g., four on each side) inside the frame 200. Figure 10 As shown, because the front and rear heights of the internal space formed by the ribs 221 are different, multiple smaller first rotor mechanisms 410A can make full use of the space, which also increases safety.

[0070] Furthermore, such as Figure 11 As shown, the longitudinal beam 210 is preferably set as two parallel rods connected together by several vertical rods to form a square-shaped strip frame. The transverse beam 220 is set as an elliptical (or rectangular) strip frame with different heights at the front and back, and they are fixedly connected to each other to form an integrated frame 200. In this way, the interior not only has a wider space to accommodate multiple first rotor mechanisms 410A, but also the airflow is smoother during operation.

[0071] Operating principle of Example 3: When the flying car needs to travel on land, since its land-based 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. When the mother-daughter sleeve 300 on the frame 200 is extended, it covers the first rotor mechanism 410A that covers the entire frame 200 and the internal space, and longitudinally covers the body 100, forming front and rear covers that are lower than the passenger cabin 120. It also protects and covers the internal first rotor mechanism 410A, forming the overall form of an electric vehicle that travels on land.

[0072] If short-distance, small-scale aerial flight is required, rotating the frame 200 exposes the second rotor mechanism 410B inside the front and rear of the vehicle body 100. Activating the telescopic mechanism 500 controls the movement of the sub-tube 320 inside the mother tube 300 into the mother tube 310, or the second sub-tube 330 and sub-tube 320 simultaneously move into the mother tube 310, exposing the frame 200 and the internal first rotor mechanism 410A. Simultaneously, multiple first motors 413 are activated, causing the second rotor mechanism 410B inside the front and rear of the vehicle body 100, as well as the internal first rotor mechanism 410A of the frame 200, to rotate. This allows the vertically take-off and landing upward propulsion power unit 400 to provide the necessary lift, forming a vertically ascending multi-rotor flying car.

[0073] If long-distance cruise flight is required, the lift provided by the frame 200 (with lifting wings) can be used for horizontal cruise flight, allowing takeoff and landing without a runway. This is also highly energy-efficient, safe, and comfortable. First, the rotating device 600 is controlled to rotate the frame 200 90 degrees in the longitudinal direction to fix it in the lateral direction. At this time, the two ends of the frame 200 are placed horizontally in the width direction facing the vehicle body 100, forming a cross shape perpendicular to the vehicle body 100. The second rotor mechanism 410B in the front and rear of the vehicle body of the cockpit 120 is not obstructed by airflow. Then, the daughter cylinder 320 and the second daughter cylinder 330 in the mother cylinder 300 are all moved into the mother cylinder 310. Further, at the same time, the rotor blades 411 on the second rotor mechanism 410B inside the vehicle body 100 and the first rotor mechanism 410A inside the frame 200 are controlled to rotate at high speed, propelling the flying car upward to a suitable height. Then, the culvert fan 420 at the rear of the car is opened to propel it forward. During the forward movement, the telescopic mechanism 500 is controlled to drive the fan in the mother cylinder 300... The sub-tube 320 extends and moves gradually towards both ends along the frame 200. Then, it closes the first row (two) of the first rotor mechanisms 410A on both sides of the frame 200, closest to the vehicle body 100. After the sub-tube 320 covers the first row of first rotor mechanisms 410A on both sides, it closes the second row (two) of first rotor mechanisms 410A on both sides. Then, both the sub-tube 320 and the second sub-tube 330 move and extend away from the main tube 330, fully covering the frame 200 and automatically locking. The first rotor mechanisms 410 on the frame 200... A is hidden inside the mother-daughter sleeve 300, so it will not generate drag and turbulence during cruise flight. Also, because the extended mother-daughter sleeve 300 forms a wing shape, the asymmetrical structure creates different airflow and air pressure, giving the mother-daughter sleeve 300 a lift function while in motion. The lift generated can support the weight of the flying car and its passengers. Then, the rotating propellers on the second rotor mechanism 410B inside the front and rear of the body 100 are shut off and stop rotating, and the car can enter a stable horizontal cruise state. It is very energy-efficient and safe.When preparing for landing, after the horizontal flight decelerates to a suitable speed, the lift generated by the mother-daughter sleeve 300 is insufficient to counteract all downward gravity. The rotor 411 on the second rotor mechanism 410B within the vehicle body 100 is then rotated to assist the mother-daughter sleeve 300 in providing upward lift. As the flying car decelerates forward and its horizontal speed approaches a stop, the daughter sleeve 320 and the second daughter sleeve 330 are again controlled to move in opposite directions and lock into the mother sleeve 310. The first rotor mechanism 410A within the frame 200 is then activated. At this point, all lifting and lowering movements... The propulsion is provided by the propulsion power unit 400 within the vehicle body 100 and frame 200. The culvert fan 420 can be shut off to stop forward propulsion. Under the control of the rotor mechanism 410, the vehicle slowly and vertically descends to the ground. Further, after stopping rotation, the mother-daughter sleeve 300 is extended again, covering the entire frame 200 and the internal first rotor mechanism 410A. The rotating device 600 is controlled to rotate the frame 200 90 degrees laterally to a longitudinal position, forming the front and rear covers of the vehicle body, which can then be used for parking or for land driving.

[0074] The various aspects of the embodiments described above can be combined or substituted with each other without mutual exclusion. Embodiment 1 is a lightweight car. A relatively small rotating device 600 can be provided on the top of the body 100 to connect the frame 200, and a propulsion device 400 can be installed on the lower part of the tail wing. The telescopic mechanism 500 also includes other structures (such as hydraulic telescopic, pneumatic telescopic, etc.). The rotor mechanism 410 can be provided with a relatively small rotating device 600 to form a tilting rotor. The flying car can drive on land and fly at low altitudes. It can be configured for manual or automatic driving. For greater energy saving and safety, the mother-daughter sleeve 300 needs to be integrally constructed of a sturdy metal material (such as aluminum alloy). Several support rods 230 (not shown in the figure) are evenly connected at intervals on all frames 200 to strengthen the stable support of the mother-daughter sleeve 300. The rotor mechanism 410 can be installed inside the mother-daughter sleeve 300. Alternatively, it can be installed only on the outer side of the frame 200 outside the sleeve 300. The body needs to use more lightweight materials (such as carbon fiber and aluminum alloy). For flight, the weight of the body needs to be limited. It is recommended to set a speed limit when driving on land for safety. During flight, although the rotating device 600 can automatically lock the rotation angle when it stops, in order to make the frame 200 and the body 100 perpendicular to form a more stable cross shape, a corresponding through hole is set at the same position of the annular slider 610 and the circular groove 620 of the rotating device 600. A pin can be inserted manually or electrically. Alternatively, a limit block is set on the circular groove 620 to limit the turning angle of the annular slider 610 of the rotating device 600. In this way, the wing 200 and the body 100 are fixed perpendicularly to form a cross shape for greater stability and safety. A sunroof can be set on the top of the cockpit 120, so that people can enter and exit through the door 140 in normal times and exit through the sunroof in an emergency.

[0075] 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.
