Description

Technical Field

[0001] This invention belongs to the technical field of gliders, specifically relating to a foldable, vertically extendable, non-phase wing coupling tandem wing device. Background Technology

[0002] Tandem wing configuration, as an aerodynamic design for aircraft, typically refers to multiple sets of main lifting surfaces arranged longitudinally along the fuselage. Existing tandem wing glider systems generally consist of a canard and a rear wing fixedly connected by a rigid support structure. The angle of attack of each wing set is usually a fixed value or has only a very small, invariable range. During flight, the lift and drag generated by each wing surface are coupled to provide the aircraft with the required flight performance.

[0003] During use, its wings are fixed and cannot be folded for storage. Since tandem wings are composed of multiple wings, their overall size is usually larger than that of a traditional monoplane layout. This non-foldable rigid structure causes the glider to occupy a large amount of space when not in use, which not only increases the cost and complexity of transportation and storage, but also makes the wings susceptible to damage from impacts during handling.

[0018] 2. With the help of the stabilizing components, when the front wing is folded, the compression column pushes the bending plate to move, which in turn causes the insertion column to be inserted into the hole of the rear folded wing to achieve radial locking.

During flight, the protective shell and its internal stabilizing mechanisms can be removed as a whole, eliminating the potential negative impact of its added weight and shape on flight performance. During transport, it can be quickly installed to protect the wings, thus balancing the needs of flight performance optimization and ground transport protection. Attached Figure Description

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

[0035] Example 1

[0036] Reference Figure 1 - Figure 6 This is the first embodiment of the present invention. This embodiment provides a foldable vertically extendable out-of-phase airfoil coupling tandem wing device, which achieves the effect of folding and storing the wing 11. It includes an adjustment component, including a vertical cylinder 10 and the wing 11. A limiting sleeve 12 is fixedly connected to the outside of the vertical cylinder 10, and a fan-shaped guide plate 13 is fixedly connected to the outside of the vertical cylinder 10. Both the limiting sleeve 12 and the fan-shaped guide plate 13 are limited on the surface of the vertical cylinder 10 by screws and nuts. The height of the wing 11 can be adjusted according to actual needs. A folding component 14 for storing the wing 11 is provided on the outside of the vertical cylinder 10, and a rotating component 15 is provided on the outside of the wing 11.

[0037] Specifically, the vertical cylinder 10 serves as the core support structure of the entire device. Two vertical cylinders 10 are installed one in front of the other on the top of the glider. The limiting sleeve 12 and the fan-shaped guide plate 13 on it work together to set the vertical height of different wings 11 by adjusting their fixed positions on the vertical cylinder 10, thereby realizing the vertical extension layout of the tandem wings. The folding assembly 14 is the core function that enables the wings 11 to rotate, fold, and unfold around the vertical cylinder 10. The rotating assembly 15 is specifically used to drive the trailing edge adjustment plate 146 to deflect, and is the actuator for adjusting aerodynamic performance.

[0038] Furthermore, the folding assembly 14 includes a rotating frame 141 rotatably connected to the outside of the vertical cylinder 10. A rotating plate 142 is fixedly connected to the outside of the rotating frame 141. The rotating plate 142 is rotatably connected to the outside of the vertical cylinder 10, and a spring positioning pin 143 is fixedly connected to the outside of the rotating plate 142. The pull rod of the spring positioning pin 143 extends out of the rotating plate 142. Pulling the pull rod unlocks the rotating plate 142. A docking block 144 is fixedly connected to one side of the rotating frame 141. The docking block 144 is fixedly connected to the wing 11. A rotating shaft 145 is rotatably connected inside the wing 11, and a trailing edge adjusting plate 146 is rotatably connected to the outside of the wing 11. The rotating frame 141 and the rotating plate 142 constitute the rotating skeleton for the folding movement of the wing 11. Their rotation around the vertical cylinder 10 directly drives the entire wing 11 to fold or unfold. The spring positioning pin 143 engages with a hole on the fan-shaped guide plate 13 to provide precise positioning and locking for the unfolded working position and the folded storage position of the wing 11. When folding the wing 11, first pull the spring positioning pin 143 to disengage it from the current hole position on the fan-shaped guide plate 13, then push the wing 11 to rotate the rotating frame 141 and the rotating plate 142 around the vertical cylinder 10 until the spring positioning pin 143 springs into another hole on the fan-shaped guide plate 13 corresponding to the storage position under the action of the spring force.

[0039] The fan-shaped guide plate 13 has through holes at positions corresponding to the spring positioning pin 143, and the spring positioning pin 143 is inserted into the through holes. When the pin head of the spring positioning pin 143 is inserted into different through holes under the action of the spring, the wing 11 is locked in that position, ensuring the stability of the structure during operation and transportation.

[0040] Furthermore, the rotating assembly 15 includes a drive motor 151 fixedly connected to the outside of the docking block 144. A first rotating block 152 is fixedly connected to the output end of the drive motor 151. A second rotating block 153 is rotatably connected to one end of the first rotating block 152. A rotating rod 154 is rotatably connected to the outside of the second rotating block 153. An L-shaped plate 155 is rotatably connected to the end of the rotating rod 154 away from the second rotating block 153. The L-shaped plate 155 is fixedly connected to the rotating shaft 145. A third rotating block 156 is fixedly connected to the outside of the rotating shaft 145. A support shaft 157 is fixedly connected to the end of the third rotating block 156 away from the rotating shaft 145. The support shaft 157 is fixedly connected to the rear edge adjusting plate 146. The drive motor 151, as a power source, converts the rotational motion of the motor into the oscillation of the rotating shaft 145 through a planar linkage mechanism composed of the first rotating block 152, the second rotating block 153, the rotating rod 154, and the L-shaped plate 155. The swing of the rotating shaft 145 is transmitted to the rear edge adjusting plate 146 through the third rotating block 156 and the support shaft 157, thereby controlling its deflection angle.

[0041] When the glider needs to be folded for transport, the operator can pull the lever of the spring positioning pin 143 to release the limit on the rotating plate 142, and then push the wing 11 to rotate around the vertical cylinder 10 through the rotating frame 141 and the rotating plate 142 until it is folded into a compact state, so that the spring positioning pin 143 corresponds and locks with another through hole of the fan-shaped guide plate 13, thus completing the folding and limiting of the wing 11. When it needs to be unfolded for work, the wing 11 is rotated to the working position, and the spring positioning pin 143 automatically springs into the corresponding hole of the fan-shaped guide plate 13 under the action of spring force to achieve positioning. During flight, when it is necessary to adjust the aerodynamic performance, the drive motor 151 can be started. The motor drives the first rotating block 152 to rotate, which in turn pushes the L-shaped plate 155 to swing through the second rotating block 153 and the rotating rod 154. The L-shaped plate 155 drives the rotating shaft 145 to rotate. The rotating shaft 145 then transmits the rotational motion to the trailing edge adjusting plate 146 through the third rotating block 156 and the support shaft 157, thereby changing its deflection angle and realizing dynamic control of lift and drag.

[0042] In summary, the spring positioning pin 143 facilitates the limiting operation of the wing 11 after a 90-degree rotation, enabling the wing 11 to rotate stably around the vertical cylinder 10 to the storage or working position, thus improving the spatial adaptability of the equipment. By starting the drive motor 151, the angle of the trailing edge adjustment plate 146 can be quickly adjusted, optimizing the lift and drag ratio under different flight conditions and significantly enhancing the overall aerodynamic performance of the aircraft.

[0043] Example 2

[0044] Reference Figure 7 - Figure 10 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a stabilizing component for the foldable vertically expandable out-of-phase wing coupling tandem wing device, which solves the problem that the wing 11 may be damaged due to shaking during transportation. It includes a protective shell 20 sleeved on the outside of the fan-shaped guide plate 13. The arc surface of the protective shell 20 is at the same center as the vertical cylinder 10. An extrusion component 21 is provided inside the protective shell 20. A limiting component 22 for supporting the wing 11 is provided inside the protective shell 20.

[0045] Specifically, the protective shell 20 serves as a carrier for the stabilizing component. The compression component 21 and the limiting component 22 housed inside work together to form an automatically triggered locking and support structure. It is particularly noteworthy that when the wing 11 needs to be folded, the protective shell 20 only needs to be installed on the outside of the front fan-shaped guide plate 13.

[0046] Furthermore, the extrusion assembly 21 includes a square rod 211 slidably connected inside the protective shell 20. One end of the square rod 211 is fixedly connected to a bending plate 212, and the other end of the square rod 211 away from the bending plate 212 is fixedly connected to a translation plate 213. The translation plate 213 is elastically connected to the protective shell 20 via a first spring 214. A push rod 215 is rotatably connected to the outside of the translation plate 213. A block 216 is fixedly connected to the inner wall of the protective shell 20, and a slide rod 217 is slidably connected inside the block 216. 17 is rotatably connected to push rod 215. A pressing column 218 is fixedly connected to the side of rotating plate 142 near protective shell 20. It is particularly noteworthy that the pressing column 218, fixed to the surface of rotating plate 142, rotates around vertical cylinder 10 along with rotating plate 142. The arc-shaped surface of bending plate 212 is at the same center as vertical cylinder 10. Therefore, after pressing column 218 presses bending plate 212 to its maximum distance, pressing column 218 will move on the arc-shaped surface of bending plate 212, preventing bending plate 212 from moving further. In use, as pressing column 218 rotates with rotating plate 142, its cylindrical surface contacts and presses the inclined surface of bending plate 212, forcing bending plate 212 to move linearly along square rod 211 and translation plate 213, compressing the first spring 214. The linear motion of the translation plate 213 is converted into the linear motion of the slide bar 217 within the vertical block 216 by the push rod 215, which facilitates the subsequent limiting and support work of the wing 11.

[0047] The protective shell 20 has a through groove at the position corresponding to the bending plate 212, and the bending plate 212 is slidably connected in the through groove. The through groove provides a path for the movement of the bending plate 212, so that the bending plate 212 squeezed by the compression column 218 can move.

[0048] Furthermore, the limiting component 22 includes a U-shaped seat 221 slidably connected to the inner wall of the protective shell 20. The U-shaped seat 221 is fixedly connected to the slide rod 217. The U-shaped seat 221 is elastically connected to the upright block 216 via a second spring 222. A post 223 is fixedly connected to the end of the U-shaped seat 221 away from the slide rod 217. The post 223 is slidably connected to the protective shell 20. A guide block 224 is fixedly connected to the inner wall of the U-shaped seat 221. A guide groove 225 is formed inside the guide block 224. A roller 226 is slidably connected inside the guide groove 225. A lifting support block 227 is fixedly connected to the outside of 226. A limiting rod is fixedly connected to the inner wall of the U-shaped seat 221. When the lifting support block 227 moves to the maximum distance, as the U-shaped seat 221 continues to move, the limiting rod will insert into the lifting support block 227 to provide support for the lifting support block 227 again, further ensuring the stability of the lifting support block 227 and reducing the force on the roller 226 and the guide block 224. An extension block 228 is fixedly connected to the outside of the wing 11. The lifting support block 227 and the extension block 228 are slidably connected. The limiting component 22 receives the linear motion from the extrusion component 21 and decomposes it into two actions: first, the U-shaped seat 221 drives the insert 223 to insert into the hole of the rear wing 11 to achieve radial locking; second, through the cooperation of the guide groove 225 on the guide block 224 and the roller 226, the horizontal movement of the U-shaped seat 221 is converted into the vertical movement of the lifting support block 227, so that it moves and subsequently locks the extension block 228 of the wing 11, providing vertical support, which facilitates the support and limiting work of the four wings 11.

[0049] The protective shell 20 has a through groove at the position corresponding to the lifting support block 227, and the lifting support block 227 is slidably connected in the through groove. The through groove provides a path and constraint for the lifting support block 227 to lift, ensuring that the lifting support block 227 can lift smoothly.

[0050] The wing 11 has a through hole at the corresponding position of the insert 223, and the insert 223 is inserted into the through hole. The through hole and the insert 223 cooperate with each other to support and limit the end of the rear wing 11, thereby ensuring the stability of the rear wing 11 during transportation.

[0051] In use, after moving the two rear wings 11 to the middle area of ​​the vertical cylinder 10, the rear wings 11 are first rotated and folded into a stowed state. Then, the protective shell 20 is installed on the outside of the front fan-shaped guide plate 13. At this time, the extrusion column 218 is in contact with the surface of the protective shell 20. When the front wings 11 are rotated, the extrusion column 218 and the rotating plate 142 rotate around the vertical cylinder 10. The extrusion column 218 slides on the arc surface of the protective shell 20. When the extrusion column 218 is about to contact the bending plate 212, the trailing edge adjusting plate 146 passes over the lifting support block 227. As the extrusion column 218 extrudes the inclined surface of the bending plate 212, the bending plate 212, the square rod 211 and the translation plate 213 move, which stretches the first spring 214. With the cooperation of the push rod 215, the slide rod 217 drives the U-shaped seat 221 to move, which stretches the second spring 222. As the U-shaped base 221 moves, the insert 223 extends out of the protective shell 20 and finally inserts into the pre-set hole on the rear wing 11, which is already in place, to support and limit the rear wing. When the U-shaped base 221 moves, the guide block 224 fixed on the U-shaped base 221 moves accordingly. The guide groove 225 inside the block forces the roller 226 rolling inside to move upward. The roller 226 drives the lifting support block 227 to move, so that the lifting support block 227 moves to the path of the extension block 228. After the front wing 11 is rotated to the retracted state, the lifting support block 227 engages with the extension block 228, completing the support work for the four wings 11, which facilitates the transportation of the glider. When it is necessary to unfold the wings 11, the front wing 11 is unfolded and reset first, and then the protective shell 20 is removed, so that the rear wing 11 can be unfolded.

[0052] In summary, by pressing the bending plate 212 with the extrusion column 218, the insertion column 223 is gradually inserted into the through hole of the rear wing 11, which facilitates the limiting support of the rear wing 11. Before the front wing 11 is in place, the lifting support block 227 can move to the moving path of the extension block 228, so that the front wing 11 can be limited and supported after it is in the folded state, thereby ensuring the stability of the four wings 11 and facilitating the smooth transport of the glider.

[0053] Example 3

[0054] Reference Figure 11 - Figure 12 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a disassembly component for a foldable vertically extendable tandem wing coupling device, which solves the problem that the protective shell 20 may have a potential negative impact on the glider's flight performance. It includes a clamp 30 disposed outside the vertical tube 10, and a positioning component 31 for limiting the clamp 30 is disposed outside the protective shell 20.

[0055] Specifically, the clamp 30 and the positioning component 31 together constitute a quick-clamping mechanism, the core function of which is to achieve reliable connection and convenient separation of the protective shell 20. When ground transportation is required, the protective shell 20 is firmly installed by the clamp 30 and the positioning component 31, enabling it to perform its protective and stabilizing functions; when the aircraft needs to perform flight missions, the protective shell 20 can be quickly removed to eliminate the impact of its weight and aerodynamic drag on flight performance.

[0056] Furthermore, the positioning component 31 includes a first stud 311 fixedly connected to the outside of the protective shell 20, a clamp 30 disposed outside the first stud 311, a first nut 312 threadedly connected to the outside of the first stud 311, a rubber pad 313 fixedly connected to the inner wall of the clamp 30, a positioning post 314 fixedly connected to the outside of the sector guide plate 13, the positioning post 314 being slidably connected to the protective shell 20, and a second stud 315 fixedly connected to the end of the positioning post 314 away from the sector guide plate 13, the second stud 315 being threadedly connected to the outside of the second stud 315, and a second nut 316. The positioning post 314 engages with the corresponding hole on the protective shell 20 to achieve preliminary radial positioning, ensuring that the protective shell 20 is fitted onto the outside of the sector guide plate 13. The clamp 30 clamps the protective shell 20 onto the vertical cylinder 10 with clamping force, and the rubber pad 313 inside increases friction and protects the surface of the vertical cylinder 10. The first stud 311, the first nut 312, the second stud 315, and the second nut 316 apply axial clamping force, which, combined with the radial clamping force of the clamp 30, forms a reliable fixation.

[0057] When using the glider and transporting it with the protective shell 20 installed, first align the positioning holes on the protective shell 20 with the positioning pins 314 on the fan-shaped guide plate 13 to achieve initial positioning. Then, place the clamp 30 on the outside of the vertical cylinder 10, and pass the first stud 311 on the protective shell 20 through the corresponding mounting hole of the clamp 30. At this time, the rubber pad 313 on the inner wall of the clamp 30 will be in close contact with the surface of the vertical cylinder 10 to increase friction. Next, screw the first nut 312 into the first stud 311 and tighten it, so that the protective shell 20 is tightly held on the vertical cylinder 10 by the clamp 30. Finally, screw the second nut 316 into the second stud 315 at the end of the positioning pin 314 that has passed through the protective shell 20 and tighten it to ensure that the protective shell 20 will not loosen during transport vibrations. When the glider needs to perform a flight mission, simply loosen and remove the second nut 316 and the first nut 312 in reverse order to quickly remove the entire protective shell 20 along with its internal stabilizing components.

[0058] In summary, the positioning post 314 facilitates the quick positioning of the protective shell 20, allowing it to fit over the fan-shaped guide plate 13. The first stud 311 and the first nut 312 work together to limit the clamp 30, thus initially limiting the protective shell 20 and facilitating the transfer of force from the protective shell 20 to the vertical cylinder 10. The second stud 315 and the second nut 316 securely limit the protective shell 20 to the outside of the fan-shaped guide plate 13, ensuring its stability.
