Description

Technical Field

[0001] This utility model relates to the field of aircraft technology, specifically to a foldable wing and an aircraft. Background Technology

[0002] Currently, small aircraft are widely developed, with fixed-wing drones being a well-known type that has been applied in various industries. Because fixed-wing drones are mostly fixed-wing or multi-rotor aircraft, they have long wingspans and large volumes. Therefore, fixed-wing drones mostly use taxiing takeoff, that is, taking off by using landing gear on roads or airports. Since taxiing takeoff requires airport runways or roads, it is highly dependent on the location in practical applications and has relatively poor maneuverability. Currently, aircraft are also popular as toys, but toy aircraft mostly have fixed wings or multi-rotor wings and cannot flexibly change their wings. Utility Model Content

[0003] The technical problem to be solved by this invention is to improve the flexibility of aircraft.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A foldable wing includes a wing section, a wing section, a connecting structure, a transition component, and a driving device. The two ends of the wing section are respectively rotatably connected to the two wing sections through the connecting structure. The driving device is connected to the wing section through the transition component and drives the wing section to fold or unfold relative to the wing section.

[0005] The beneficial effects of this utility model are: under the drive of the drive device, the adapter component drives the two sections of the wing to be folded or unfolded through the connecting structure, thereby flexibly changing the way the wing is used and improving the diversity and flexibility of the wing.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the connection structure includes a first connecting shaft, a second connecting shaft, and a transition structure. The first connecting shaft is fixedly connected to one section of the wing. There are two second connecting shafts, and each of the two second connecting shafts is fixedly connected to one of the two sections of the wing. The two ends of the first connecting shaft are rotatably connected to one end of each of the two second connecting shafts through the transition structure.

[0008] The beneficial effects of adopting the above-mentioned further solution are: the setting of connecting shaft one and connecting shaft two makes the wing more stable, and the two ends of connecting shaft one are respectively connected to one end of the two connecting shafts two through a transition structure, so that the wing can be flexibly changed to a folding or unfolding mode.

[0009] Furthermore, the adapter assembly includes a slider and a connecting rod. The driving device is connected to the slider and causes the slider to reciprocate linearly in the front-back direction. One end of the connecting rod is fixedly connected to the slider, and the other end of the connecting rod is fixedly connected to one end of the second section of the wing.

[0010] The beneficial effect of adopting the above-mentioned further solution is that, driven by the drive device, the slider moves linearly back and forth, thereby driving the wing to fold or unfold in two sections through the connecting rod.

[0011] Furthermore, the connection structure includes a first connecting shaft and a second connecting shaft. The first connecting shaft is fixedly connected to a first section of the wing, and there are two second connecting shafts, each fixedly connected to a second section of the wing. The adapter assembly includes a rotating shaft, one end of which is fixedly connected to the second connecting shaft. Both ends of the first connecting shaft are rotatably engaged with one end of each of the two second connecting shafts via the rotating shaft. The drive device is fixedly connected to a first section of the wing, and the output end of the drive device is connected to the other end of the rotating shaft.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the setting of connecting shaft one and connecting shaft two makes the wing more stable, and one end of the rotating shaft is fixedly connected to one end of connecting shaft two, while the other end of the rotating shaft is connected to the output end of the drive device. Thus, under the drive of the drive device, the rotating shaft drives connecting shaft two to rotate, thereby completing the folding or unfolding of the two sections of the wing, so that the wing can flexibly change to a folding or unfolding mode.

[0013] Furthermore, the angle α between the plane containing the first connecting shaft and the first section of the wing is 45 degrees, and the angle b between the plane containing the second connecting shaft and the second section of the wing is 45 degrees.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the setting of the angle between the plane containing the first connecting shaft and the first section of the wing, and the setting of the angle between the second connecting shaft and the second section of the wing, are both for the purpose of achieving the preset state after the second section of the wing is folded.

[0015] Furthermore, the first connecting shaft includes a straight section and two bent sections, and the second connecting shaft includes a straight section and two bent sections. The two ends of the straight section are respectively fixedly connected to one end of the two bent sections, and one end of the straight section is fixedly connected to one end of the bent section. The other end of the bent section and the other end of the corresponding bent section are rotatably connected through the adapter structure.

[0016] The beneficial effect of adopting the above-mentioned further solution is that: the connecting shaft one is set as a straight part one and two bent parts one, and the connecting shaft two is set as a straight part two and a bent part two, which makes it convenient to set the corresponding angle between the straight part one and the bent part one and between the straight part two and the bent part two, so that the preset angle state can be achieved after the two sections of the wing are folded.

[0017] Furthermore, the angle c between the first straight section and the first bent section is 120.2 degrees to 130.2 degrees, and the angle d between the second straight section and the second bent section is 120.2 degrees to 130.2 degrees.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that setting the angle c between the first straight part and the first bent part to 120.2 degrees-130.2 degrees, and setting the angle d between the second straight part and the second bent part to 120.2 degrees-130.2 degrees, corresponds to the angle between the first connecting shaft and the plane containing the first section of the wing and the plane containing the second connecting shaft and the second section of the wing, so that the second section of the wing can continuously provide lift during the folding or extension process of the second section of the wing.

[0019] Furthermore, a propeller mechanism is provided at the front end of the second wing section. The propeller mechanism includes a propeller and a propeller motor. The propeller and the propeller motor are connected in a driving connection, and the propeller motor is fixedly connected to the second wing section.

[0020] The beneficial effect of adopting the above-mentioned further scheme is that by setting up a propeller mechanism, lift and forward propulsion are provided.

[0021] This utility model also provides an aircraft, including a fuselage and the aforementioned foldable wing, wherein a section of the wing and the drive device are both fixedly connected to the fuselage.

[0022] The beneficial effect is that when the wings are folded, the aircraft can take off vertically, thereby improving the aircraft's flexibility and adaptability.

[0023] Furthermore, the foldable wing is one, with one section of the wing located at the front of the fuselage; or the foldable wing is two, with one section of the wing located at the bottom front of the fuselage and the other section of the wing located at the top rear of the fuselage.

[0024] The beneficial effects of adopting the above-mentioned further scheme are: by setting a foldable wing, the aircraft can take off vertically when the wing is folded, which improves the flexibility and adaptability of the aircraft; by setting two foldable wings at different heights, with the front foldable wing set at the bottom of the fuselage and the rear foldable wing set at the top of the fuselage, more lift is provided during ascent, making the flight lighter and faster.

[0034] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0035] Example 1

[0036] like Figures 1-5 As shown, this embodiment provides a foldable wing, including a wing section 10, a wing section 20, a connecting structure, a connecting component, and a driving device. The two ends of the wing section 10 are respectively rotatably connected to the two wing sections 20 through the connecting structure. The driving device is connected to the wing section 20 through the connecting component and drives the wing section 20 to fold or unfold relative to the wing section 10.

[0037] The drive unit drives the second section 20 of the wing in the first position (e.g.) Figure 1The position of the two wing sections 20 shown) and the second position (as shown) Figure 2 The wing section 20 can be switched between positions (as shown) and rotated relative to the first wing section 10 during the transition between the first and second positions. In the first position, the wing section 20 extends outward along the first wing section 10; in the second position, the wing section 20 folds inward along the first wing section 10.

[0038] Driven by the drive unit, the adapter component enables the second section 20 of the wing to be folded or unfolded through the connecting structure, thereby flexibly changing the way the wing is used and improving the versatility and flexibility of the wing.

[0039] Specifically, the front end of the first wing section 10 is wide and the rear end is narrow, forming a convex shape. One end of the second wing section 20 matches one end of the first wing section 10, and the connecting rod 34 is located on the protruding part at the rear end of the second wing section 20.

[0040] Based on any of the above schemes, the connection structure includes a first connecting shaft 31, a second connecting shaft 32, and a transition structure 33. The first connecting shaft 31 is fixedly connected to the first section of the wing 10. There are two second connecting shafts 32, and the two second connecting shafts 32 are fixedly connected to the two second sections of the wing 20 in a one-to-one correspondence. The two ends of the first connecting shaft 31 are respectively rotatably connected to one end of the two second connecting shafts 32 through the transition structure 33.

[0041] Specifically, connecting shaft 1 31 is embedded inside the first section of wing 10 and fixedly connected to the first section of wing 10, connecting shaft 2 32 is embedded inside the second section of wing 20 and fixedly connected to the second section of wing 20, and the transition structure 33 is located at the connection between the front edge of the first section of wing 10 and the edge of the front recessed part of the second section of wing 20.

[0042] By setting up connecting shaft 1 31 and connecting shaft 2 32, the wing is made more stable. The two ends of connecting shaft 1 31 are respectively connected to one end of the two connecting shafts 2 32 through the adapter structure 33, so that the wing can be flexibly changed to folding or unfolding mode.

[0043] Based on any of the above solutions, the adapter assembly includes a slider 41 and a connecting rod 34. The driving device is connected to the slider 41 and causes the slider 41 to move linearly back and forth in the front-back direction. One end of the connecting rod 34 is fixedly connected to the slider 41, and the other end of the connecting rod 34 is fixedly connected to one end of the second section 20 of the wing.

[0044] Driven by the drive device, the slider 41 moves linearly back and forth, thereby driving the second section 20 of the wing to fold or unfold via the connecting rod 34.

[0045] Specifically, the driving device is a linear motor.

[0046] Specifically, a limit block 42 is provided at the rear end of the track on which the slider 41 moves back and forth.

[0047] When slider 41 moves backward, the second section 20 of the wing begins to fold. When slider 41 comes into contact with limit block 42, the second section 20 of the wing is fully folded.

[0048] Based on any of the above schemes, the angle α between the plane containing the first connecting shaft 31 and the first section of the wing 10 is 45 degrees, and the angle b between the plane containing the second connecting shaft 32 and the second section of the wing 20 is 45 degrees.

[0049] The angle between the plane containing the first connecting shaft 31 and the first section of the wing 10, and the angle between the plane containing the second connecting shaft 32 and the second section of the wing 20, are all designed so that the second section of the wing 20 can reach a preset state after folding.

[0050] Based on any of the above solutions, the connecting shaft 31 includes a straight section 311 and two bent sections 312, and the connecting shaft 32 includes a straight section 321 and a bent section 322. The two ends of the straight section 311 are fixedly connected to one end of each of the two bent sections 312. One end of the straight section 321 is fixedly connected to one end of the bent section 322. The other end of the bent section 312 and the other end of the corresponding bent section 322 are rotatably connected through the adapter structure 33.

[0051] The connecting shaft 31 is configured as a straight section 311 and two bent sections 312, and the connecting shaft 32 is configured as a straight section 321 and a bent section 322. This allows for setting corresponding angles between the straight section 311 and the bent section 312, as well as between the straight section 321 and the bent section 322, so that the preset angle can be achieved after the second section 20 of the wing is folded.

[0052] Specifically, the angle α between the straight section 311 and the plane containing the first section 10 of the wing is 45 degrees, and the angle b between the straight section 321 and the plane containing the second section 20 of the wing is 45 degrees.

[0053] Specifically, the adapter structure 33 includes screws, nuts and washers, and a through hole 1 is provided at the other end of the bending part 312, and a through hole 2 is provided at the other end of the bending part 322.

[0054] The gasket consists of multiple gaskets, which are either metal gaskets or rubber gaskets. ， Metal gaskets and rubber gaskets are used alternately.

[0055] In a specific example, the screw passes through through hole one, a metal washer, a rubber washer, another metal washer, and through hole two in sequence, and is secured by a nut.

[0056] Optionally, a metal washer, a rubber washer, and a metal washer can be sequentially placed between the through hole and the nut.

[0057] Based on any of the above schemes, the angle c between the straight part 311 and the bent part 312 is 120.2 degrees to 130.2 degrees, and the angle d between the straight part 321 and the bent part 322 is 120.2 degrees to 130.2 degrees.

[0058] The angle c between the straight section 311 and the bent section 312 is set to 120.2 degrees-130.2 degrees, and the angle d between the straight section 321 and the bent section 322 is set to 120.2 degrees-130.2 degrees. This corresponds to the angle between the connecting shaft 31 and the plane containing the first section of the wing 10, and the angle between the connecting shaft 32 and the plane containing the second section of the wing 20, so that the second section of the wing 20 can continuously provide lift during the folding or extension process.

[0059] In a specific example, the angle c between the straight section 311 and the bent section 312 is 125.2 degrees, and the angle d between the straight section 321 and the bent section 322 is 125.2 degrees. Driven by the linear motor, the slider 41 drives the connecting rod 34 and pushes the second wing section 20 to fold. When the second wing section 20 is fully folded, the plane of the second wing section 20 is exactly perpendicular to the plane of the first wing section 10.

[0060] Based on any of the above schemes, a propeller mechanism is provided at the front end of the second wing section 20. The propeller mechanism includes a propeller and a propeller motor. The propeller and the propeller motor are connected in a driving connection, and the propeller motor and the second wing section 20 are fixedly connected.

[0061] By incorporating a propeller mechanism, lift and forward propulsion are provided.

[0062] Specifically, each wing section 20 is equipped with at least two propeller mechanisms.

[0063] The propeller mechanism provides better power to the aircraft.

[0064] In one specific example, such as Figure 1 and Figure 2 As shown, there are two propeller mechanisms.

[0065] Alternatively, the propeller mechanism can also be three, four or more.

[0066] Specifically, it also includes a controller, which is electrically connected to multiple propeller motors and linear motors.

[0067] By setting up the controller to be electrically connected to multiple propeller motors and linear motors, remote control and operation are possible.

[0068] This embodiment also provides an aircraft, including a fuselage and the aforementioned foldable wing, wherein a section 10 of the wing and the drive device are both fixedly connected to the fuselage.

[0069] When the wings are folded, the aircraft can take off vertically, thereby improving its flexibility and adaptability.

[0070] In a specific example, the angle c between the straight section 311 and the bent section 312 is 125.2 degrees, and the angle d between the straight section 321 and the bent section 322 is 125.2 degrees. The remote controller and the controller are connected and can remotely control the aircraft. The linear motor is controlled by the remote controller. When the slider 41 moves forward, it pushes the connecting rod 34. The connecting rod 34 applies a pulling force to the rear end of the second wing section 20, causing the second wing section 20 to rotate around the connecting structure. The second wing section 20 folds. When the second wing section 20 is fully folded, the plane of the second wing section 20 is perpendicular to the plane of the first wing section 10. Figure 2 As shown, the remote control can control the propeller motor. When the propeller motor is started, the rotation of the propeller provides maximum lift, allowing the aircraft to take off without gliding. After full takeoff, by controlling the linear motor, the slider 41 moves backward, pulling the connecting rod 34. The connecting rod 34 applies a pulling force to the rear end of the second wing section 20, causing the second wing section 20 to rotate around the connecting structure. At this time, the second wing section 20 slowly unfolds. When the slider 41 slides to abut against the limit block 42, the second wing section 20 is fully unfolded. At this time, the plane of the second wing section 20 coincides with the plane of the first wing section 10 (e.g., ...). Figure 1 As shown), the remote controller can continue to remotely control the aircraft to fly forward. The aircraft can also fly forward while the second wing section 20 is deployed, and it can also fly normally when the second wing section 20 is partially deployed.

[0071] Driven by the drive unit, the second wing section 20 folds or unfolds while rotating through the connecting structure, which can flexibly change the way the wing is used. The aircraft can take off and land without relying on the road surface for taxiing distance. The foldable wing can maintain flight while rotating, folding or unfolding, further improving the versatility and flexibility of the aircraft.

[0072] Example 2

[0073] like Figures 4-7As shown, this embodiment provides a foldable wing, including a wing section 10, a wing section 20, a connecting structure, a connecting component, and a driving device. The two ends of the wing section 10 are respectively rotatably connected to the two wing sections 20 through the connecting structure. The driving device is connected to the wing section 20 through the connecting component and drives the wing section 20 to fold or unfold relative to the wing section 10.

[0074] Driven by the drive unit, the adapter component enables the second section 20 of the wing to be folded or unfolded through the connecting structure, thereby flexibly changing the way the wing is used and improving the versatility and flexibility of the wing.

[0075] Based on any of the above schemes, the connection structure includes a first connecting shaft 31, a second connecting shaft 32, and a transition structure 33. The first connecting shaft 31 is fixedly connected to the first section of the wing 10. There are two second connecting shafts 32, and the two second connecting shafts 32 are fixedly connected to the two second sections of the wing 20 in a one-to-one correspondence. The two ends of the first connecting shaft 31 are respectively rotatably connected to one end of the two second connecting shafts 32 through the transition structure 33.

[0076] Specifically, connecting shaft 1 31 is embedded inside the first section of wing 10 and fixedly connected to the first section of wing 10, connecting shaft 2 32 is embedded inside the second section of wing 20 and fixedly connected to the second section of wing 20, and the transition structure 33 is located at the connection between the front edge of the first section of wing 10 and the edge of the front recessed part of the second section of wing 20.

[0077] By setting up connecting shaft 1 31 and connecting shaft 2 32, the wing is made more stable. The two ends of connecting shaft 1 31 are respectively connected to one end of the two connecting shafts 2 32 through the adapter structure 33, so that the wing can be flexibly changed to folding or unfolding mode.

[0078] Based on any of the above schemes, the connection structure includes a first connecting shaft 31 and a second connecting shaft 32. The first connecting shaft 31 is fixedly connected to the first wing section 10. There are two second connecting shafts 32, and the two second connecting shafts 32 are fixedly connected to the two second wing sections 20 in a one-to-one correspondence. The adapter assembly includes a rotating shaft 43, one end of which is fixedly connected to the second connecting shaft 32. The drive device is fixedly connected to the first wing section 10. The two ends of the first connecting shaft 31 are respectively rotatably engaged with one end of each of the two second connecting shafts 32 through the rotating shaft 43. The output end of the drive device is drively connected to the other end of the rotating shaft 43.

[0079] The connection shaft 31 and the connection shaft 32 make the wing more stable. One end of the rotating shaft 43 is fixedly connected to one end of the connection shaft 32, and the other end of the rotating shaft 43 is connected to the output end of the drive device. Thus, under the drive of the drive device, the rotating shaft 43 drives the connection shaft 32 to rotate, thereby completing the folding or unfolding of the two sections 20 of the wing, so that the wing can flexibly change to a folding or unfolding mode.

[0080] Specifically, the driving device is a rotary motor.

[0081] Based on any of the above schemes, the angle α between the plane containing the first connecting shaft 31 and the first section of the wing 10 is 45 degrees, and the angle b between the plane containing the second connecting shaft 32 and the second section of the wing 20 is 45 degrees.

[0082] The angle between the plane containing the first connecting shaft 31 and the first section of the wing 10, and the angle between the plane containing the second connecting shaft 32 and the second section of the wing 20, are all designed so that the second section of the wing 20 can reach a preset state after folding.

[0083] Based on any of the above solutions, the connecting shaft 31 includes a straight section 311 and two bent sections 312, and the connecting shaft 32 includes a straight section 321 and a bent section 322. The two ends of the straight section 311 are fixedly connected to one end of each of the two bent sections 312. One end of the straight section 321 is fixedly connected to one end of the bent section 322. The other end of the bent section 312 and the other end of the corresponding bent section 322 are rotatably connected through the adapter structure 33.

[0084] The connecting shaft 31 is configured as a straight section 311 and two bent sections 312, and the connecting shaft 32 is configured as a straight section 321 and a bent section 322. This allows for setting corresponding angles between the straight section 311 and the bent section 312, as well as between the straight section 321 and the bent section 322, so that the preset angle can be achieved after the second section 20 of the wing is folded.

[0085] Specifically, the angle α between the straight section 311 and the plane containing the first section 10 of the wing is 45 degrees, and the angle b between the straight section 321 and the plane containing the second section 20 of the wing is 45 degrees.

[0086] Based on any of the above schemes, the angle c between the straight part 311 and the bent part 312 is 120.2 degrees to 130.2 degrees, and the angle d between the straight part 321 and the bent part 322 is 120.2 degrees to 130.2 degrees.

[0087] The angle c between the straight section 311 and the bent section 312 is set to 120.2 degrees-130.2 degrees, and the angle d between the straight section 321 and the bent section 322 is set to 120.2 degrees-130.2 degrees. This corresponds to the angle between the connecting shaft 31 and the plane containing the first section of the wing 10, and the angle between the connecting shaft 32 and the plane containing the second section of the wing 20, so that the second section of the wing 20 can continuously provide lift during the folding or extension process.

[0088] In a specific example, the angle c between the straight section 311 and the bent section 312 is 125.2 degrees, and the angle d between the straight section 321 and the bent section 322 is 125.2 degrees. Driven by the rotary motor, the rotating shaft 43 drives the connecting shaft 32 to rotate, thereby folding the second wing section 20. When the second wing section 20 is fully folded, the plane of the second wing section 20 is exactly perpendicular to the plane of the first wing section 10.

[0089] Based on any of the above schemes, a propeller mechanism is provided at the front end of the second wing section 20. The propeller mechanism includes a propeller and a propeller motor. The propeller and the propeller motor are connected in a driving connection, and the propeller motor and the second wing section 20 are fixedly connected.

[0090] By incorporating a propeller mechanism, lift and forward propulsion are provided.

[0091] Specifically, each wing section 20 is equipped with at least one propeller mechanism.

[0092] The propeller mechanism provides better power to the aircraft.

[0093] In one specific example, such as Figure 7 As shown, each of the two sections 20 of the wing has one propeller mechanism.

[0094] Specifically, it also includes a controller, which is electrically connected to multiple propeller motors and rotary motors.

[0095] By setting up the controller to be electrically connected to multiple propeller motors and rotary motors, remote control and operation are possible.

[0096] This embodiment also provides an aircraft, including a fuselage and the aforementioned foldable wing, wherein a section 10 of the wing and the drive device are both fixedly connected to the fuselage.

[0097] When the wings are folded, the aircraft can take off vertically, thereby improving its flexibility and adaptability.

[0098] In a specific example, the angle c between the straight section 311 and the bent section 312 is 125.2 degrees, and the angle d between the straight section 321 and the bent section 322 is 125.2 degrees. There are two foldable wings, one wing section 10 located at the front bottom of the fuselage, and the other wing section 10 located at the rear top of the fuselage. The remote controller and the controller communicate and can remotely control the aircraft. The remote controller controls the rotary motor, whose output shaft and rotating shaft 43 are connected, thereby driving the second wing section 20 to rotate and fold. When the second wing section 20 is fully folded, the plane of the second wing section 20 is perpendicular to the plane of the first wing section 10. The remote controller can also control the propeller motor. When the propeller motor is started, the propeller rotation provides maximum lift, allowing the aircraft to take off without gliding. After full takeoff, the rotary motor drives the rotating shaft 43 to rotate in the opposite direction, causing the second wing section 20 to slowly unfold. When the second wing section 20 is fully unfolded, its plane coincides with the plane of the first wing section 10, allowing the remote controller to continue remotely controlling the aircraft to fly forward. The aircraft can fly forward even while the second wing section 20 is unfolding, and it can also fly normally when the second wing section 20 is partially unfolded. By using two foldable wings at different heights—the front foldable wing located at the bottom of the fuselage and the rear foldable wing at the top—more lift is provided during ascent, resulting in smoother and more agile flight, while also saving energy.
