Description

Technical Field

[0001] This utility model belongs to the field of aircraft technology, and in particular relates to an aircraft wing-body structure with a quick connection function. Background Technology

[0002] A wing-body structure for aircraft with quick connection function is a modular and high-efficiency connection system designed specifically for docking aircraft wings and fuselages. Its core is to significantly shorten the assembly and disassembly cycle of wings and fuselages through innovative mechanical interfaces, intelligent locking mechanisms and adaptability design, while strictly ensuring the structural strength, aerodynamic integrity and load transfer reliability of the aircraft, and taking into account the special structural assembly with ease of maintenance, environmental adaptability and multi-scenario application capabilities.

[0003] When connecting the wings and fuselage of an existing aircraft, it usually requires two workers to work together to hold the fuselage and wings and align the connection holes. Then, the wings and fuselage are fixed together with several rivets and connecting blocks. This method lacks an effective pre-connection structure, which means that workers need to spend a certain amount of time to align the multiple connection holes of the fuselage and wings. It is not only time-consuming and labor-intensive, but also difficult for a single person to complete the connection work. Utility Model Content

[0004] The purpose of this invention is to provide an aircraft wing-body structure with a quick-connect function. Specifically, during installation, the two conical blocks of the wing are aligned with the two conical grooves of the wing root. Then, the connecting post is inserted into the slot, which compresses and pushes the two locking blocks away from each other. When inserted to the limit, the locking blocks lose their compression, and a spring pushes them into the slots, completing the connection. During disassembly, the threaded rod is rotated clockwise, causing it to move downwards, simultaneously moving the toothed block downwards. The toothed block then rotates the connecting post counterclockwise by 90 degrees, compressing the two locking blocks and disengaging them from their corresponding slots, thus completing the disassembly. This structure allows for quick installation and removal of the wing and wing root, enabling a single person to complete the subsequent installation work. It solves the problem that existing aircraft fuselage and wing connections often require two workers to align multiple connection holes before using rivets and connecting plates for fixation. However, this method lacks an effective pre-connection mechanism, resulting in a lengthy and labor-intensive process for aligning the fuselage and wing connection holes, making it difficult for a single person to complete the entire operation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an aircraft wing-body structure with a quick-connect function, comprising a fuselage, wing roots fixedly connected to the left and right sides of the fuselage, and wings provided on the left and right sides of the fuselage. Two connecting blocks are installed at the top and bottom of the wing roots and wings. Link tubes are provided inside the wing roots and wings. The structure also includes: a connecting mechanism located inside the wing roots and wings, used for quick connection between the wing roots and wings; the connecting mechanism includes two connecting posts with two slots on their outer surfaces; two locking blocks are provided inside the wing roots, and the locking blocks are inserted into the slots; and a sealing mechanism located inside the wing roots, used to seal between the wing roots and wings. The link tubes inside the wing roots and wings are interconnected, and these link tubes accommodate the connecting lines controlling the wing's control surfaces. The sealing mechanism ensures a good seal between the wing roots and wings, effectively preventing rainwater from entering the link tubes and causing connection line malfunctions.

[0007] Furthermore, the connecting mechanism includes several springs. Two conical blocks are fixedly connected to the sides of the two wings that are close to each other. Two conical grooves are opened on the sides of the two wing roots that are far from each other. The conical blocks are inserted into the conical grooves. Two lifting grooves are opened inside the wing roots. The locking block is slidably limited to the lifting grooves. One end of the spring is fixedly connected to the inner wall of the lifting groove. The end of the spring near the locking block is fixedly connected to the side of the locking block away from the connecting post. The end of the conical block away from the wing is conical. The two conical blocks and the conical grooves work together to prevent the connected wing roots and wings from rotating. The connecting post and the locking block work together to prevent the wing from detaching from the wing roots. The combined action of both ensures a stable connection between the wing roots and the wing.

[0008] Furthermore, the sealing mechanism includes two annular blocks, the two annular blocks being fixedly connected at opposite sides to the two wings at adjacent sides, and annular grooves being provided on opposite sides of the two wing roots, with the annular blocks being inserted into the annular grooves; both the annular blocks and the annular grooves are annularly arranged.

[0009] Furthermore, gears are fixedly connected to the two connecting columns on opposite sides. A circular groove and a vertical groove are provided inside the wing. A toothed block is slidably fitted on the inner wall of the vertical groove. The toothed block meshes with the gear. The connecting column is rotatably connected to the inside of the wing. The circular groove and the toothed block are interconnected. The circular groove is used to accommodate the gear and to prevent the connecting column from detaching from the wing.

[0010] Furthermore, a threaded groove is provided at the bottom of the wing, and a threaded rod is threadedly connected to the inner wall of the threaded groove. A round block is fixedly connected to the top of the threaded rod, and both the threaded rod and the round block are rotatably connected to the inside of the toothed block; an internal hexagonal groove is provided at one end of the bottom of the threaded rod.

[0011] Furthermore, a movable ring block is slidably limited to the inner wall of the annular groove. A sealing ring is installed on the side of the movable ring block near the wing. Several springs are fixedly connected to the inner wall of the annular groove. The ends of the springs near the wing are fixedly connected to the side of the movable ring block away from the wing. The sealing ring is made of rubber. The springs are used to prevent the movable ring block from dislodging from the annular groove. The springs can prevent the movable ring block and the sealing ring from dislodging from the annular groove.

[0012] Furthermore, an adjustment groove is provided inside the wing root, and an eccentric column is provided inside the adjustment groove. A threaded rod is fixedly connected to the bottom of the eccentric column. A threaded groove is provided at the bottom of the wing root, and the threaded rod is threadedly connected to the threaded groove. The annular groove and the adjustment groove are interconnected. One end of the bottom of the threaded rod is provided with an internal hexagonal groove. When the threaded rod moves up and down, it will drive the eccentric column to move together. The length of the adjustment groove is greater than the length of the eccentric column, so that it can move up and down smoothly. Moreover, the length of the eccentric column is much greater than the width of the inner ring of the moving ring block, so that the eccentric column can always maintain stable contact with the moving ring block when it moves. Furthermore, the threaded rod can self-lock with the threaded groove, so that the eccentric column will not easily rotate.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, through the setting of a connecting mechanism, specifically, during installation, first aligns the two conical blocks of the wing with the two conical grooves of the wing root, then inserts the connecting post into the slot, which will squeeze and push the two locking blocks away from each other. When inserted to the limit, the locking blocks lose their squeezing force, and the spring force pushes them into the slot, completing the connection. During disassembly, the threaded rod is rotated clockwise, and as it moves downward, it drives the toothed block to move downward as well. The toothed block will drive the connecting post to rotate 90 degrees counterclockwise, squeezing the two locking blocks to make them leave the corresponding slots, thus completing the disassembly. This structure can quickly install and remove the wing and wing root, allowing a single person to complete the subsequent installation work.

[0015] 2. This utility model, through the setting of a sealing mechanism, specifically, when the wing and wing root are connected, the annular block one is inserted into the annular groove and squeezes the sealing ring to deform it and fill the surrounding gaps, thus completing the sealing operation. When the sealing ring undergoes slight deformation due to thermal expansion and contraction, resulting in a poor sealing effect, the threaded rod two can be rotated clockwise. As it moves upward, it drives the eccentric column to rotate clockwise. The convex end of the eccentric column will push the moving ring block to move towards the wing, working together with the annular block one to squeeze the sealing ring, allowing it to continue to deform and fill the gaps. This mechanism can flexibly move the moving ring block, ensuring that it can always squeeze the sealing ring and maintain the stability of the seal to adapt to different temperature environments.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-7As shown, this utility model is an aircraft wing-body structure with a quick-connect function, including a fuselage 1, with wing roots 11 fixedly connected to the left and right sides of the fuselage 1, and wings 12 provided on the left and right sides of the fuselage 1. Two connecting blocks 121 are installed at the top and bottom of the wing roots 11 and the wings 12. Link pipes 13 are provided inside the wing roots 11 and the wings 12. It also includes: a connecting mechanism 2, which is located inside the wing roots 11 and the wings 12, and is used to quickly connect the wing roots 11 and the wings 12. The connecting mechanism 2 includes two connecting posts 22, with two slots 221 on the outer surface of the connecting posts 22. Two locking blocks 224 are provided inside the wing roots 11, and the locking blocks 224 are inserted into the slots 221; a sealing mechanism 3, which is located inside the wing roots 11, and is used to seal between the wing roots 11 and the wings 12; the link pipes 13 inside the wing roots 11 and the wings 12 are interconnected. The connecting mechanism 2 includes several springs 225. Two conical blocks 21 are fixedly connected to the sides of the two wings 12 that are close to each other. Two conical grooves 211 are opened on the sides of the two wing roots 11 that are far from each other. The conical blocks 211 are inserted into the conical grooves 211. Two lifting grooves 223 are opened inside the wing roots 11. A locking block 224 is slidably limited to the lifting grooves 223. One end of the spring 225 is fixedly connected to the inner wall of the lifting groove 223, and the end of the spring 225 near the locking block 224 is fixedly connected to the side of the locking block 224 that is far from the connecting post 22. The end of the conical block 21 that is far from the wing 12 is conical. The sealing mechanism 3 includes two annular blocks 31. The sides of the two annular blocks 31 that are far from each other are fixedly connected to the sides of the two wings 12 that are close to each other. Annular grooves 32 are opened on the sides of the two wing roots 11 that are far from each other, and the annular blocks 31 are inserted into the annular grooves 32. Both the annular blocks 31 and the annular grooves 32 are annular. Gears 23 are fixedly connected to the two connecting posts 22 on opposite sides. A circular groove 231 and a vertical groove 24 are provided inside the wing 12. A toothed block 241 is slidably limited to the inner wall of the vertical groove 24. The toothed block 241 meshes with the gear 23. The connecting post 22 is rotatably connected to the inside of the wing 12. The circular groove 231 and the toothed block 241 are interconnected. The circular groove 231 is used to accommodate the gear 23 and to prevent the connecting post 22 from detaching from the wing 12.The wing 12 has a threaded groove 25 at its bottom. A threaded rod 251 is threadedly connected to the inner wall of the threaded groove 25. A round block 252 is fixedly connected to the top of the threaded rod 251. Both the threaded rod 251 and the round block 252 are rotatably connected to the inside of the toothed block 241. During installation, first align the two conical blocks 21 of the wing 12 with the two conical grooves 211 of the wing root 11. Then, insert the connecting post 22 into the slot 222. This will squeeze and push the two locking blocks 224 away from each other. When inserted to the limit, the locking blocks 224 lose their squeezing force. When pressed, the spring 225 pushes the threaded rod 251 into the slot 221 to complete the connection. When disassembling, the threaded rod 251 is rotated clockwise. As it moves downward, the toothed block 241 moves downward as well. The toothed block 241 will drive the connecting column 22 to rotate 90 degrees counterclockwise, squeezing the two slots 224 to make them leave the corresponding slots 221 to complete the disassembly. This structure can quickly install and remove the wing 12 and wing root 11, allowing a single person to complete the subsequent installation work. The bottom end of the threaded rod 251 has an internal hexagonal groove.

[0029] The inner wall of the annular groove 32 is fitted with a sliding limiter, and a sealing ring 322 is installed on the side of the moving ring block 321 near the wing 12. Several springs 323 are fixedly connected to the inner wall of the annular groove 32. The ends of the springs 323 near the wing 12 are fixedly connected to the side of the moving ring block 321 away from the wing 12. The sealing ring 322 is made of rubber, and the springs 323 are used to prevent the moving ring block 321 from disengaging from the annular groove 32. An adjustment groove 33 is provided inside the wing root 11, and an eccentric column 331 is provided inside the adjustment groove 33. A threaded rod 332 is fixedly connected to the bottom of the eccentric column 331. A threaded groove 333 is provided at the bottom of the wing root 11, and the threaded rod 332 is threadedly connected to the threaded groove 333. When the wing 12 and the wing root 11 are connected, the annular block 31 is inserted into the annular groove 32 and squeezes the sealing ring 322 to deform it and fill the surrounding gaps, thus completing the sealing operation. When the sealing ring 322 undergoes slight deformation due to thermal expansion and contraction, resulting in a poor sealing effect, it can be adjusted clockwise. The needle rotates the threaded rod 332, which moves upward and drives the eccentric column 331 to rotate clockwise. The protruding end of the eccentric column 331 pushes the moving ring block 321 to move towards the wing 12, cooperating with the annular block 31 to compress the sealing ring 322, allowing it to continue to deform to fill the gap. This mechanism can flexibly move the moving ring block 321 so that it can always compress the sealing ring 322, maintaining the stability of the seal and adapting to different temperature environments. The annular groove 32 and the adjusting groove 33 are interconnected, and an internal hexagonal groove is opened at one end of the bottom of the threaded rod 332.

[0030] A specific application of this embodiment is as follows: In use, first align the two conical blocks 21 on the wing 12 with the two conical grooves 211 on the wing root 11, then insert the connecting post 22 into the slot 222. The conical head of the connecting post 22 will squeeze and push the two locking blocks 224 away from each other. The spring 225 connected to the locking block 224 is compressed at the same time. While the connecting post 22 is squeezing the locking block 224, the conical block 21 has entered the conical groove 211. When the connecting post 22 is inserted to the limit position, the two locking blocks 224 lose their compression, and several springs 225 push the two locking blocks 224 closer to each other through their own elasticity, and insert them into the two slots 221 of the connecting post 22. At this time, the wing root 11 and the wing 12 are connected. Then, use four connecting blocks 121 to screw the top of the wing root 11 and the wing 12. During the connection of the wing root 11 and the wing 12, the annular block 31 will be inserted into the annular groove 32. Since the moving ring block 321 is blocked by the eccentric column 331, the annular block 31 will squeeze the sealing ring 322 to deform it and fill the surrounding gap, thus completing the sealing of the wing root 11 and the wing 12. When the sealing ring 322 deforms slightly due to thermal expansion and contraction, it will not be able to fill the surrounding gap, resulting in a poor sealing effect. At this time, a wrench can be inserted into the internal hexagonal groove at the bottom of the threaded rod 332 and rotated clockwise to move the eccentric column 331 down. At the same time, the convex end of the eccentric column 331 will squeeze and push the moving ring block 321 towards the wing 12. At this time, the moving ring block 321 will squeeze the sealing ring 322 again to deform it and fill the surrounding gap. The same operation is performed on the other side of the wing root 11 and the wing 12.

[0031] When disassembling wing 12, insert a wrench into the hexagonal socket at the bottom of threaded rod 251 and turn it clockwise. At this time, threaded rod 251 will drive toothed block 241 to move down together. At this time, toothed block 241 will drive gear 23 and connecting column 22 to rotate counterclockwise together. Connecting column 22 will squeeze and push the two locking blocks 224 away from each other until toothed block 241 moves down to the limit position. At this time, connecting column 22 has rotated 90 degrees. At this time, both locking blocks 224 have left the corresponding locking slots 221. Wing 12 can then be pulled away from fuselage 1 to complete disassembly. The other wing 12 is operated in the same way.
