[0001] The present invention relates to the field of flying cars, and particularly to a wing folding structure of a flying car and a flying car. Background Art

[0002] In recent years, with the continuous development of innovative technologies such as aerospace control, intelligent transportation, and modern communication, the concept of flying cars has emerged. Different from ordinary aircraft, flying cars not only require high flight requirements but also need to meet the need to drive normally on ground lanes. As a manned aircraft, a flying car needs relatively long wings to provide the lift required for flight. At the same time, in order to meet the requirements of road driving, the flying car must maintain the same external dimensions as a traditional car. Therefore, the wings of the flying car need to be designed as folding wings, and sufficient strength should be ensured when the wings are deployed.

[0046] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0047] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those skilled in the art will appreciate the applicability of other processes and / or the use of other materials.

[0048] Reference below Figures 1 - 10 A flying car wing folding structure 100 according to an embodiment of the present invention is described.

[0049] like Figures 1 - 9 As shown, the flying car wing folding structure 100 according to an embodiment of the present invention includes: a fixed wing 20 and a rotating wing 40.

[0050] The rotating wing 40 is rotatably connected to the fixed wing 20, and the rotating wing 40 has a folded position and an unfolded position. One of the fixed wing 20 and the rotating wing 40 has a first connecting portion 21, and the other has a second connecting portion 41. When the rotating wing 40 is in the unfolded position, the first connecting portion 21 is fixedly engaged with the second connecting portion 41. When the rotating wing 40 is in the folded position, the first connecting portion 21 and the second connecting portion 41 are separated.

[0051] Thus, when the rotary wing 40 is in the deployed position, the first connecting portion 21 and the second connecting portion 41 are fixedly matched, thereby enhancing the connection strength between the rotary wing 40 and the fixed wing 20 and enhancing the structural stability of the rotary wing 40, so that the rotary wing 40 can withstand the bending moment during flight, thereby allowing the flying car 1000 to fly in the air in fixed-wing mode.

[0052] For example, the fixed wings 20 are fixedly mounted on the flying car 1000, and two rotating wings 40 are provided, which are symmetrically distributed on both sides of the fixed wings 20. When the rotating wings 40 are in the deployed position, the rotating wings 40 and the fixed wings 20 are deployed in a straight line, so that the flying car 1000 can have sufficient lift when flying in the air. During the process of rotating the rotating wings 40 from the deployed position to the folded position, the rotating wings 40 rotate and retract relative to the fixed wings 20 toward the rear of the flying car 1000. When the rotating wings 40 are in the folded position, the width of the wing folding structure 100 is approximately the width of the vehicle body, thereby reducing the impact on the width dimension of the flying car 1000 and allowing the flying car 1000 to travel on conventional roads.

[0053] It should be noted that in the related art, when the rotary wing 40 is deployed, the connection strength between the rotary wing 40 and the fixed wing 20 is relatively low, resulting in the rotary wing 40 being unable to withstand the bending moment during flight, so that the flying car 1000 cannot stably fly in the fixed-wing mode in the air.

[0054] In the present invention, when the rotary wing 40 is in the deployed position, the rotary wing 40 and the fixed wing 20 can enhance the connection strength between the rotary wing 40 and the fixed wing 20 through the fixed cooperation of the first connection portion 21 and the second connection portion 41, so that the rotary wing 40 of the flying car 1000 can withstand the bending moment during flight when it is in the deployed position, and the rotary wing 40 maintains the fixed-wing mode during flight.

[0055] According to the wing folding structure 100 of a flying car of an embodiment of the present invention, a rotary wing 40 is rotatably connected to a fixed wing 20. The rotary wing 40 has a folded position and a deployed position. When the rotary wing 40 is in the deployed position, the first connection portion 21 and the second connection portion 41 are fixedly engaged, so as to be able to enhance the connection strength between the rotary wing 40 and the fixed wing 20, and to enhance the structural stability of the rotary wing 40, so that the rotary wing 40 can withstand the bending moment during flight, so that the flying car 1000 flies in the fixed-wing mode in the air.

[0056] In some embodiments, as Figure 7 and Figure 9 shown, one of the first connection portion 21 and the second connection portion 41 is configured as a support rod 22, and the other is configured as a plug-in groove 42, and the support rod 22 is adapted to be plugged and cooperated with the plug-in groove 42.

[0057] Thus, when the rotary wing 40 is deployed, the support rod 22 can be inserted into the plug-in groove 42 to enhance the connection strength between the rotary wing 40 and the fixed wing 20, and the support rod 22 being plugged into the plug-in groove 42 makes the support rod 22 not directly visible outside the wing folding structure 100, which is convenient for reducing the influence on the size of the wing folding structure 100 and facilitating the realization of the miniaturized design of the wing folding structure 100.

[0058] For example, when the first connection portion 21 is configured as the support rod 22, the second connection portion 41 is configured as the plug-in groove 42, and vice versa. In this embodiment, the first connection portion 21 is configured as the support rod 22, the second connection portion 41 is configured as the plug-in groove 42, and the support rod 22 is cooperated with the plug-in groove 42.

[0059] For example, the first connecting portion 21 can be disposed on the fixed wing 20. At this time, the second connecting portion 41 is disposed on the rotary wing 40, and vice versa. In this embodiment, the first connecting portion 21 is disposed on the fixed wing 20, and the second connecting portion 41 is disposed on the rotary wing 40. In this way, the support rod 22 is provided on the fixed wing 20, and the insertion slot 42 is provided on the rotary wing 40. When the rotary wing 40 is in the deployed position, the support rod 22 can be inserted into the insertion slot 42 to enhance the connection strength between the rotary wing 40 and the fixed wing 20, so that the rotary wing 40 can withstand the bending moment during flight.

[0060] In some embodiments, as Figure 7 and Figure 9 shown, the support rod 22 is installed on the fixed wing 20, the insertion slot 42 is provided on the rotary wing 40, and the fixed wing 20 is provided with a driving member 25. When the rotary wing 40 is in the deployed position, the driving member 25 is used to drive the support rod 22 to move in a direction close to or away from the insertion slot 42.

[0061] Thus, by providing the driving member 25, when the support rod 22 is inserted and engaged with the insertion slot 42, the movement of the support rod 22 does not need to be manually controlled, so as to improve the automation degree of the wing folding structure 100.

[0062] For example, when the rotary wing 40 is in the deployed position, the driving member 25 can drive the support rod 22 to move in a direction close to the insertion slot 42 so that the support rod 22 can extend into the insertion slot 42. Or, when the rotary wing 40 moves from the deployed position to the folded position, the driving member 25 drives the support rod 22 to move in a direction away from the insertion slot 42 so that the support rod 22 is separated from the insertion slot 42, so that the rotary wing 40 can rotate on the fixed wing 20.

[0063] In this way, the movement of the support rod 22 can be driven by the driving member 25 to improve the automation degree of the wing folding structure 100.

[0064] In some embodiments, as Figure 2 and Figure 7 shown, the fixed wing 20 is provided with an installation cavity 23, and the support rod 22 is slidably installed in the installation cavity 23.

[0065] Thus, the support rod 22 is not directly visible outside the fixed wing 20, which is beneficial to reducing the influence on the size of the fixed wing 20 and facilitating the miniaturized design of the fixed wing 20.

[0066] Meanwhile, when the rotary wing 40 is in the deployed position, the support rod 22 can slide from the installation cavity 23 towards the insertion slot 42 so that the end of the support rod 22 can extend into the insertion slot 42, thereby enhancing the connection strength between the rotary wing 40 and the fixed wing 20. When the rotary wing 40 needs to move from the deployed position to the folded position, the end of the support rod 22 moves from the insertion slot 42 into the installation cavity 23, so that the movement of the rotary wing 40 is not restricted.

[0067] It should be noted that when the rotary wing 40 is in the deployed position, the open mouth of the installation cavity 23 is directly opposite to the open mouth of the insertion slot 42. At the same time, the inner wall of the installation cavity 23 can guide and limit the movement of the support rod 22 to ensure that the support rod 22 can directly move into the insertion slot 42.

[0068] In some embodiments, as Figure 6 shown, the driving member 25 is configured as a driving motor, the driving motor is located on the motor mounting surface 231 in the installation cavity 23, and the support rod 22 includes a first sub-rod 26 and a second sub-rod 27. The first sub-rod 26 is fixedly connected to the output shaft of the driving motor, and the second sub-rod 27 is sleeved outside the first sub-rod 26. Wherein, an external thread is provided on the outer peripheral wall of the first sub-rod 26, and an internal thread is provided on the inner peripheral wall of the second sub-rod 27, and the external thread and the internal thread are threadedly connected.

[0069] Thus, when the driving member 25 drives the first sub-rod 26 to rotate, the rotation of the first sub-rod 26 can drive the second sub-rod 27 to move along the axial direction of the first sub-rod 26.

[0070] Thus, when the rotary wing 40 is in the deployed position, the driving motor drives the first sub-rod 26 to rotate and then drives the second sub-rod 27 to move along the axial direction of the first sub-rod 26, so that the end of the first sub-rod 26 extends into the insertion slot 42, thereby enhancing the connection strength between the rotary wing 40 and the fixed wing 20. When the rotary wing 40 moves from the deployed position to the folded position, the driving motor drives the first sub-rod 26 to rotate and then controls the second sub-rod 27 to leave the insertion slot 42, so that the rotary wing 40 can be folded.

[0071] Optionally, when the first sub-rod 26 is fixedly connected to the output shaft of the driving motor, there can be various connection forms. For example, when the first sub-rod 26 is connected to the output shaft of the driving motor, it can be directly inserted on the output shaft, or when the first sub-rod 26 is connected to the output shaft of the driving motor, they are fixedly connected together by threaded connection. Preferably, in this embodiment, the first sub-rod 26 is directly inserted on the output shaft of the driving motor.

[0072] Optionally, after the first sub-rod 26 and the second sub-rod 27 are threaded together, the thread directions of the two are not limited. For example, when the first sub-rod 26 rotates clockwise to drive the second sub-rod 27 close to the plug-in slot 42, the first sub-rod 26 rotates counterclockwise to drive the second sub-rod 27 away from the plug-in slot 42, or when the first sub-rod 26 rotates clockwise to drive the second sub-rod 27 to move away from the plug-in slot 42, the first sub-rod 26 rotates counterclockwise to drive the second sub-rod 27 to move toward the direction close to the plug-in slot 42.

[0073] In some embodiments, as Figure 7 As shown, the first sub-rod 26 includes a rod body 261 and a connecting portion 262 . The external thread is provided on the outer peripheral wall of the rod body 261 . The connecting portion 262 is connected to the rod body 261 and is sleeved on the outer side of the output shaft of the driving motor.

[0074] In other words, the outer peripheral wall of the rod body 261 of the first sub-rod 26 is provided with an external thread that matches the internal thread on the inner peripheral wall of the second sub-rod 27, so that the first sub-rod 26 can drive the second sub-rod 27 to move toward or away from the plug-in slot 42. The connecting portion 262 of the first sub-rod 26 is sleeved on the outside of the output shaft of the driving motor, and the connecting portion 262 is connected to the rod body 261, so that the driving motor can drive the second sub-rod 27 by driving the first sub-rod 26.

[0075] Therefore, in this embodiment, the first sub-rod 26 is sleeved on the output shaft of the drive motor, which makes it more convenient to connect the first sub-rod 26 to the output shaft of the drive motor, and the first sub-rod 26 is coaxial with the output shaft of the drive motor after installation, so that the power of the drive motor can be better transmitted to the first sub-rod 26.

[0076] In some embodiments, as Figure 7 As shown, a bearing 28 is further provided in the installation cavity 23 , and the bearing 28 is sleeved on the outer side of the connecting portion 262 .

[0077] It can be understood that the bearing 28 in the installation cavity 23 is sleeved on the outer side of the connecting portion 262, and the bearing 28 can better fix the first sub-rod 26 on the driving motor.

[0078] Optionally, a support rod mounting groove 232, a bearing outer ring mounting surface 233 and a bearing outer ring pressure cover mounting surface 234 are provided in the mounting cavity 23 of the fixed wing 20. The support rod 22 is first installed in the support rod mounting groove 232, and then the bearing 28 is placed on the bearing outer ring mounting surface 233. At this time, the connecting portion 262 of the first sub-rod 26 will be stuck in the bearing 28, and a bearing outer ring pressure cover 281 and a bearing inner ring pressure cover 282 are provided on the side of the bearing 28 close to the drive motor. The bearing outer ring pressure cover 281 is installed on the bearing outer ring pressure cover mounting surface 234 by a threaded connection, and the bearing inner ring pressure cover 282 is sleeved on the connecting portion 262 of the first sub-rod 26, so as to limit the bearing 28, so that the bearing 28 can limit the connecting portion 262 of the first sub-rod 26, so that the first sub-rod 26 can be better connected to the output shaft of the drive motor.

[0079] In some embodiments, as Figures 1 - 5 As shown, the fixed wing 20 includes a fixed frame and a rotating base 37 , the fixed frame is connected to the rotating base 37 , the rotating base 37 is provided with a rotating rod 38 , the rotating rod 38 is rotatably connected to the rotating base 37 , and the rotating rod 38 is connected to the rotating wing 40 .

[0080] Specifically, the fixed frame is connected to the rotating base 37, and a base 30 is provided in the rotating base 37, on which a self-lubricating copper ring 32 is installed. One end of a rotating rod 38 provided in the rotating base 37 is connected to the rotating wing 40, and the other end is connected to the hinge 43 of the fixed frame. The rotating rod 38 can drive the rotating wing 40 to move on the fixed wing 20, so that the rotating wing 40 has a folded position and an unfolded position.

[0081] Thus, the fixing frame is connected to the rotating base 37 so that the rotating base 37 can provide a mounting point for the rotating wing 40 . After the rotating wing 40 is mounted on the rotating base 37 , the rotating rod 38 is used to drive the rotating wing 40 to move.

[0082] It should be noted that, in this embodiment, the fixing frame can be constructed as a mid-section wing section 36 .

[0083] For example, the fixed wing 20 includes a middle wing section 36 and a rotating base 37, wherein the middle wing section 36 includes parts such as wing spars, longitudinal masts, spars and ribs, and its structure is similar to the ordinary wing structure in the relevant technology. The cross-section of the rotating base 37 is an airfoil structure, and the rotating base 37 is provided with a mounting cavity 23 and a base-base mounting surface 371. The rotating wing 40 is rotatably arranged on the rotating base 37 of the fixed wing 20, and the rotating wing 40 includes a hinge 43, a rotating rod 38, a rotating plate 46, a transition connection section 44 and an outer wing section 45, wherein the structure of the outer wing section 45 is the same as that of the middle wing section 36.

[0084] Wherein, rotating bases 37 are provided at both ends of the middle wing section 36. A base 30 is installed in the rotating base 37. A self-lubricating copper ring 32 is sleeved on the base 30. Two rotating wings 40 are symmetrically arranged at both ends of the fixed wing 20. One end of a hinge 43 is installed on the middle wing section 36 of the fixed wing 20, and the other end of the hinge 43 is connected to a rotating rod 38. The hinge 43 and the rotating rod 38 can be connected by a pin. The rotating plate 46 is configured as a flat plate structure with one end being arc-shaped. A self-lubricating copper ring mounting hole 306 is provided at one end of the rotating plate 46 close to the arc-shaped side. The rotating plate 46 is sleeved on the self-lubricating copper ring 32 through the self-lubricating copper ring mounting hole 306. The rotating plate 46 is connected to the end of the rotating rod 38 away from the hinge 43, and the end of the rotating plate 46 not connected to the rotating rod 38 is clamped in the transition connection section 44.

[0085] The transition connection section 44 of the rotating wing 40 is connected to and clamps the rotating plate 46 with the outer wing section 45. The transition connection section 44 connects the outer wing section 45 to the rotating plate 46 of the rotating wing 40. Therefore, when the rotating wing 40 moves from the deployed position to the folded position, the rotating rod 38 will extend and drive the rotating plate 46 to rotate 90° towards the rear of the vehicle around the self-lubricating copper ring 32, so that the outer wing section 45 can follow the rotating plate 46 and rotate 90° towards the rear of the vehicle together, realizing the folding function of the rotating wing 40.

[0086] Furthermore, when the rotating wing 40 moves from the deployed position to the folded position, the angle at which the rotating wing 40 rotates towards the rear of the vehicle is not limited. For example, the rotating wing 40 can rotate 45° towards the rear of the vehicle, or the rotating wing 40 can rotate 120° towards the rear of the vehicle. The rotation of 90° in the above embodiments is only one implementation method. When the rotating wing 40 moves from the folded position to the deployed position, the rotating rod 38 will contract and drive the rotating wing 40 to move towards the front of the vehicle. The number of degrees the rotating wing 40 rotates when folding is the same as the number of degrees it rotates when unfolding.

[0087] Thus, two rotating wings 40 are symmetrically arranged at both ends of the fixed wing 20. After the fixed wing 20 is installed on the flying car 1000, when the rotating wings 40 are in the deployed position, they can provide sufficient lift for the flying car 1000 together with the fixed wing 20. When the rotating wings 40 are folded, in the width direction of the flying car 1000, the overall width of the folding wing structure 100 in the width direction of the flying car 1000 is less than or equal to the width of the flying car 1000, so that when the flying car 1000 is driving on the road surface, the folding wing structure 100 will not affect other vehicles.

[0088] Optionally, the base 30 of the fixed wing 20 is a disc structure with a boss, on which a base-rotating base mounting surface 301, a self-lubricating copper ring mounting surface 302, a base-copper ring pressure cover mounting surface 303, a base-rotating base fixing hole 304 and a base-copper ring pressure cover fixing hole 305 are provided. A base 30 is also installed on the rotating base 37, and the base 30 and the rotating base 37 are connected together by screws, wherein the self-lubricating copper ring 32 is a hollow circular ring structure, and the self-lubricating copper ring 32 is sleeved on the boss of the base 30, and the inner ring of the self-lubricating copper ring 32 is in contact with the self-lubricating copper ring mounting surface 32, and the copper ring pressure cover 33 is connected to the base 30 and abuts against the boss, so that the self-lubricating copper ring 32 is clamped between the base 30 and the copper ring pressure cover 33.

[0089] For example, the copper ring gland 33 is constructed as a disc-shaped structure, on which a gland-base mounting surface 331 is provided. The gland-base mounting surface 331 can be mounted on the rotating base 37 by screw connection, thereby limiting the self-lubricating copper ring 32.

[0090] Furthermore, when the base 30 is connected to the rotating base 37, the screw will pass through the base-rotating base fixing hole 304, thereby fixing the base 30 and the rotating base 37 together, and the copper ring pressure cover 33 is installed on the base-copper ring pressure cover mounting surface 303, and then the screw is passed through the base-copper ring pressure cover fixing hole 305 to fix the copper ring pressure cover 33 on the base 30. At the same time, one end of the rotating rod 38 is connected to the rotating wing 40, and the other end is connected to the fixed wing 20. When the rotating rod 38 is extended and retracted, it can drive the rotating plate 46 to rotate around the self-lubricating copper ring 32, so as to drive the rotating wing 40 to rotate through the rotating plate 46.

[0091] In some embodiments, as Figure 2 As shown, the rotating base 37 is provided with a rotating sliding groove 34 , the end of the rotating wing 40 extends into the rotating sliding groove 34 , and the rotating wing 40 is provided with a fixing groove 35 , and the rotating rod 38 is inserted into the fixing groove 35 .

[0092] The rotatable wing 40 is rotated by the rotating rod 38, and the fixed groove 35 is connected to the fixed wing 20. The other end of the rotating rod 38 is connected to the fixed wing 20. When the rotating rod 38 is extended and retracted, the fixed groove 35 has enough space for the rotating rod 38 to move. At the same time, the rotating rod 38 is inserted into the fixed groove 35 so that the rotating rod 38 is located in the fixed wing 20 and can be connected to the rotating plate 46 of the rotating wing 40. This also reduces the impact on the size of the fixed wing 20, which is conducive to the miniaturization design of the fixed wing 20.

[0093] Specifically, when the fixed wing 20 is mounted on the top of the flying car 1000, the rotating sliding groove 34 is provided with an opening toward the rear of the vehicle. When the rotating wing 40 moves from the deployed position to the folded position, the rotating wing 40 rotates 90° toward the rear of the vehicle around the self-lubricating copper ring 32, and the rotating wing 40 can be stuck in the opening of the rotating sliding groove 34. In this way, the width of the folding wing structure 100 in the width direction of the flying car 1000 after the rotating wing 40 is folded is basically consistent with the width of the flying car 1000, so that the flying car 1000 will not affect other vehicles when driving normally on the road.

[0094] The present invention also provides a flying car 1000 .

[0095] like Figure 10 As shown, a flying car 1000 according to an embodiment of the present invention includes: a flying car wing folding structure 100 according to any one of the above embodiments.

[0096] According to an embodiment of the present invention, a flying car 1000 is installed with a folding wing structure 100, in which a rotating wing 40 is rotatably connected to a fixed wing 20. The rotating wing 40 has a folded position and an unfolded position. When the rotating wing 40 is in the unfolded position, the first connecting portion 21 and the second connecting portion 41 are fixedly engaged, thereby enhancing the connection strength between the rotating wing 40 and the fixed wing 20 and the structural stability of the rotating wing 40, so that the rotating wing 40 can withstand the bending moment during flight, thereby allowing the flying car 1000 to fly in the air in a fixed-wing mode.
