[0040] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0041] Embodiment 1: This embodiment provides a technical solution: an aircraft, such as Figures 1 to 8 As shown, it includes a load-bearing component 1, a flight power mechanism 2, and two disassembly and assembly connection mechanisms 3. The load-bearing component 1 is a cargo box or a manned cabin. The flight power mechanism 2 is connected to the cargo box or the manned cabin as needed to form a cargo drone or a manned multi-rotor aircraft, and realize a shared power system. It should be noted that: whether it is a cargo box or a manned cabin, there are two connecting cross bars 11 on the top thereof, which are used to cooperate with the two disassembly and assembly connection mechanisms 3.

[0042] The flight power mechanism 2 can select a suitable model on the market. In the present embodiment, the flight power mechanism 2 comprises a center frame, and a plurality of brackets are evenly distributed in a ring shape on the outer side of the center frame. A rotor system is arranged at the end of each of the plurality of brackets. The plurality of rotor systems are the power source of the aircraft, and suitable models on the market can be selected and used directly. A control system and a power supply system (not shown in the figure) are arranged on the center frame. The control system is used to receive instructions from an external controller to remotely control the operation of the aircraft, and the power supply system is used to provide power to various components of the entire aircraft. In addition, a shell (not shown in the figure) that covers the two disassembly and assembly connection mechanisms 3 may be arranged on the center frame to improve the protection performance.

[0043] Two disassembly and assembly connection mechanisms 3 are respectively arranged on both sides of the central frame of the flight power mechanism 2, and the disassembly and assembly connection mechanisms 3 are used for quickly disassembling and assembling with the connecting cross bar 11 to realize the switching of the load-bearing component 1; the disassembly and assembly connection mechanism 3 includes a fixing frame 31 fixed to the central frame of the flight power mechanism 2, the fixing frame 31 has a transverse plate and side plates fixed on both sides of the transverse plate, and a lifting assembly and a locking assembly are arranged on the fixing frame 31; the lifting assembly is used to pull the central frame of the flight power mechanism 2 and the connecting cross bar 11 of the load-bearing component 1 close to position, and the locking assembly is used to fix or loosen the lifting device and the fixing frame 31 to realize the connection or disassembly of the load-bearing component 1 and the flight power mechanism 2.

[0044] The hoisting assembly includes a rope winding member arranged on the fixed frame 31, the rope winding member includes a wire rope reel 327 and a winding roller 326 which is rotatably mounted on the upper part of the fixed frame 31 through a mounting seat, the wire rope reel 327 is arranged on the winding roller 326, a motor 328 which drives the winding roller 326 to rotate is fixed on one side of the mounting seat, the winding roller 326 can be driven to rotate by running the motor 328, the rotating winding roller 326 can loosen or reel the wire rope of the wire rope reel 327, so that the wire rope on the wire rope reel 327 is extended or shortened, a first through hole is opened on the fixed frame 31, a first guide wheel 325 and a second guide wheel 329 are installed on the fixed frame 31 to guide the end of the wire rope of the wire rope reel 327 to pass through the first through hole, and a sling is installed at the lower end of the wire rope of the wire rope reel 327. By running the output end of the motor 328, the sling can be moved vertically by its own weight.

[0045] The sling is used to connect with the connecting cross bar 11 of the load-bearing component 1. When the rope winding member winds up the wire rope, the distance between the load-bearing component 1 and the flight power mechanism 2 is shortened until the load-bearing component 1 is docked with the flight power mechanism 2, so that the center frame of the flight power mechanism 2 and the connecting cross bar 11 of the load-bearing component 1 are brought closer and positioned. Furthermore, inverted V-shaped grooves are provided on both side plates of the fixed frame 31. When the rope winding member straightens the connecting cross bar 11 and abuts against the top wall of the inverted V-shaped groove, the lateral position of the connecting cross bar 11 is positioned.

[0046] The sling includes a round rod 322 connected to the end of the wire rope of the wire rope reel 327, and a hook 321 is rotatably connected to the round rod 322 and a stopper 323 is fixed thereon. The hook 321 has a V-shaped structure at its bend, which can be stably connected to the connecting cross bar 11. When the hook 321 is in a normal state, the stopper 323 blocks the gap of the hook 321. This arrangement prevents the connecting cross bar 11 from detaching, thereby increasing safety performance.

[0047] Furthermore, a groove 111 is provided on the connecting cross bar 11, and the inner wall of the hook 321 has a protrusion 3211, and the protrusion 3211 is adapted to the groove 111 to achieve axial positioning of the hook 321 and the connecting cross bar 11, thereby avoiding deviation of the longitudinal position of the connection between the load-bearing component 1 and the flight power mechanism 2.

[0048] The locking assembly includes two groups of symmetrically arranged pushing members, and the pushing members include a vertical plate fixed to the fixed frame 31, and a linear driver 341 is fixed on the vertical plate. The linear driver 341 can be an electric push rod or a hydraulic cylinder. A clamping block 342 is fixed at the telescopic end of the linear driver 341. The clamping blocks 342 of the two pushing members fix the sling to realize the connection between the load-bearing component 1 and the flight power mechanism 2. The clamping block 342 is provided with an inclined surface on one side close to the hook 321, and the inclined surface is adapted to the outer side of the hook 321 to clamp it.

[0049] Furthermore, both side plates of the fixing frame 31 are provided with a slide groove 343, in which a slider 344 is slidably arranged, and the slider 344 is fixedly connected to the clamping block 342. The arrangement of the slide groove 343 and the slider 344 increases the load-bearing performance of the clamping block 342 and ensures safety.

[0050] In other embodiments, the linear drive 341 can also be replaced with a motor, and a screw is fixed to the output end of the motor, and the screw is threadedly connected to the clamp block 342. Through the operation of the motor, the clamp block 342 can be driven to move laterally to clamp or loosen the lifting parts.

[0051] When the present embodiment is in use, the flight power mechanism 2 is first operated to suspend it in the low air and to move it to the top of the load-bearing component 1 that needs to be replaced, i.e., the cargo box or the manned cabin. Then, the telescopic ends of the two linear actuators 341 are retracted so that the distance between the two clamping blocks 342 is larger than the lateral dimension of the hook 321. Then, the motor 328 is operated, and the steel wire rope on the steel wire rope reel 327 is gradually loosened, and the hook 321 is lowered due to its own weight until the hook 321 can be manually hooked and matched with the connecting cross bar 11 on the load-bearing component 1. Then, the motor 328 is operated in the reverse direction, and the steel wire rope of the steel wire rope reel 327 is gradually wound around the winding roller 326, so that the distance between the load-bearing component 1 and the flight power mechanism 2 can be shortened (here, the distance between the load-bearing component 1 and the flight power mechanism 2 can be shortened). The load-bearing component 1 is lifted, and the height of the flight power mechanism 2 can also be gradually lowered as the wire rope of the wire rope reel 327 is gradually shortened), until the connecting cross bar 11 abuts against the inverted V-shaped groove, and the wire rope reel 327 tightens the hook 321, so that the connecting cross bar 11 is tightly fixed on the lower side of the fixed frame 31, completing the preliminary connection between the load-bearing component 1 and the flight power mechanism 2; finally, by extending the telescopic ends of the two linear drives 341, the two clamping blocks 342 clamp the hook 321 to fix it, and finally the connection between the load-bearing component 1 and the flight power mechanism 2 is completed. The load-bearing component 1 is fixed by the tightening of the wire rope of the wire rope reel 327 and the clamping and dragging of the hook 321 by the two clamping blocks 342. These two fixing methods ensure the stability of the connection.

[0052] Embodiment 2: This embodiment is further optimized on the basis of embodiment 1, and the same parts as the above technical solution will not be repeated here. Figures 3 to 7 As shown, in order to better realize the present invention, the following setting is particularly adopted: in this embodiment, the lifting assembly also includes a pulling member, which is used to drive the hook 321 to flip over. Without human intervention, the hook 321 of the sling can be automatically flipped to open the sling, so that the sling can be automatically connected or disassembled with the connecting cross bar 11, thereby improving the automation operation.

[0053] The pulling member includes a winding drum 331 installed on the fixed frame 31, and a pull rope 332 is wound on the winding drum 331 through a spring (not shown in the figure). When not subject to other forces, the pull rope 332 will be automatically reeled onto the winding drum 331 under the action of the spring. A second through hole is opened on the fixed frame 31, and a third guide wheel 333 is installed on the fixed frame 31 to guide the end of the pull rope 332 to pass through the second through hole, and the end of the pull rope 332 is fixedly connected to the outer side of the hook 321, and the length of the pull rope 332 is limited.

[0054] When the pull rope 332 is pulled downward by the hoist to a certain size, the length of the pull rope 332 can no longer be extended, and at this time the corresponding side of the hook 321 will be lifted, and the hook 321 will be flipped with the round rod 322, so that the hook 321 is tilted, and the block 323 will no longer block the gap of the hook 321, so that the hook 321 can cooperate to hook the connecting cross bar 11. When the wire rope of the wire rope reel 327 is retracted upward, the flight power mechanism 2 also cooperates to descend, and the pull rope 332 will be reeled onto the winding drum 331 along with the clockwork spring.

[0055] Furthermore, in order to allow the sling to move vertically and ensure a stable fitting connection between the sling and the connecting cross bar 11, a telescopic rod 324 is installed on the fixed frame 31, and the lower end of the telescopic rod 324 is fixedly connected to the round rod 322, so that the sling can move downward in a straight line to avoid being affected by external forces.

[0056] Embodiment 3: This embodiment is further optimized on the basis of embodiment 1, and the same parts as the above technical solutions will not be repeated here. Figures 3 to 5 As shown, in order to better realize the present invention, the following setting method is particularly adopted: in this embodiment, the disassembly and assembly connection mechanism 3 also includes a fixing component, which is used to fix the wire rope of the wire rope reel 327 when the center frame of the flight power mechanism 2 is connected to the connecting cross bar 11 of the load-bearing component 1 to ensure the load-bearing performance of the wire rope for the sling. In this embodiment, the wire rope is preferably a flat structure to increase the clamping area.

[0057] The fixing assembly includes a bottom support block 351 fixed on the fixing frame 31, and the bottom support block 351 is located between the first guide wheel 325 and the second guide wheel 329, the wire rope between the first guide wheel 325 and the second guide wheel 329 is arranged in an inclined shape, and the upper surface of the bottom support block 351 is arranged in contact with the inclined wire rope, and the two side plates of the fixing frame 31 are provided with elastic members, and the upper ends of the two elastic members are fixedly provided with top clamping blocks 352, and a clamping block 352 is formed between the top clamping block 352 and the bottom support block 351. Holding gap, the wire rope of the wire rope reel 327 passes through the clamping gap. When subjected to force, the clamping gap will be reduced to achieve clamping of the wire rope, and the lower ends of the two elastic members are fixed with push blocks 358, the inner ends of the push blocks 358 extend to the lower side of the clamping block 342, and the upper end of the push block 358 is provided with an inclined surface close to the side of the corresponding linear drive 341, and rollers 359 in contact with the push block 358 are installed on both sides of the corresponding clamping block 342, and the rollers 359 are used to reduce the friction with the push block 358.

[0058] The elastic member includes a vertical sliding rod 353 which is slidably mounted on the side plate of the fixed frame 31 through a sliding sleeve 354. The lower side of the top clamping block 352 is arranged in an inclined shape. The top clamping block 352 and the push block 358 are respectively fixed to the upper and lower ends of the vertical sliding rod 353. A pressure block 357 is fixed on the vertical sliding rod 353. A compression spring 356 which is sleeved on the vertical sliding rod 353 is arranged between the pressure block 357 and the sliding sleeve 354. The compression spring 356 applies an upward force to the vertical sliding rod 353.

[0059] When the sling reaches the specified position, the telescopic end of the linear drive 341 is extended, so that the clamping block 342 clamps the hook 321. At the same time, the roller 359 will contact the push block 358 and push the push block 358 downward, compressing the compression spring 356. Further, the top clamping block 352 will move downward and cooperate with the bottom support block 351 to clamp and fix the wire rope, thereby reducing the force on the winding roller 326. On the contrary, when the clamping block 342 moves outward, the top clamping block 352 will move upward due to the force of the compression spring 356, thereby loosening the wire rope.

[0060] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims, but all of them will fall within the scope of protection of the present invention.
