[0057] It can be understood that, compared with the prior art which uses a conveyor belt to load and unload cargo, the present application separates the design of the transfer component 200 for transfer on the ground and the loading and unloading component 300 for transfer in the cabin 020. The loading and unloading component 300 can be detachably fixed in the cabin 020 according to loading requirements. The loading and unloading component 300 is fixed in the cabin 020, and the output end of the loading and unloading component 300 can be reliably docked with the input end of the airdrop cargo system 022. There is no need to consider the parking angle of the aircraft 010, and the cargo can be accurately loaded. At the same time, the height and width of the loading and unloading component 300 are adjustable, and the loading and unloading component 300 can be adjusted and locked in height to adapt to airdrop cargo systems 022 of different heights.

[0058] In this embodiment, the aircraft 010 is further provided with a cabin opening 021 for loading and unloading the loading assembly 030 , and the cabin opening 021 is connected to a cabin door.

[0059] In this embodiment, the auxiliary loading and unloading system 040 has a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other.

[0060] In this embodiment, aircraft 010 includes auxiliary loading and unloading system 040 .

[0061] The auxiliary loading and unloading system 040 is used to assist in loading and unloading the loading assembly 030 loaded with goods.

[0062] In this embodiment, the auxiliary loading and unloading system 040 includes a loading and unloading assembly 300 .

[0063] Among them, the loading and unloading component 300 is used to transfer the loading component 030 located on the loading and unloading component 300 to the airdrop cargo system 022.

[0064] In this embodiment, please refer to Figure 8 The loading and unloading component 300 can be detachably arranged in the cabin 020, the loading and unloading component 300 is docked with the airdrop cargo system 022, and the output end of the loading and unloading component 300 is connected to the input end of the airdrop cargo system 022; the transfer component 200 is used to transfer the loading component 030 to the loading and unloading component 300 and to transfer the loading component 030 located on the loading and unloading component 300.

[0065] It can be understood that by separately designing the transfer component 200 for transfer on the ground and the loading and unloading component 300 for transfer in the cabin 020, the loading and unloading component 300 can be detachably fixed in the airport according to loading needs. The loading and unloading component 300 is fixed in the cabin 020, and the output end of the loading and unloading component 300 can be reliably docked with the input end of the airdrop cargo system 022. There is no need to consider the parking angle of the aircraft 010, and the precise loading of the cargo can be completed.

[0066] In this embodiment, please refer to Figure 8-Figure 9 The loading and unloading assembly 300 includes a loading and unloading platform 310, a slider 320 and a driving assembly 330. The loading and unloading platform 310 is detachably arranged in the cabin 020 and docked with the airdrop cargo system 022 along the first direction X; the slider 320 is slidably arranged on the loading and unloading platform 310 along the first direction X, and the driving assembly 330 is arranged on the loading and unloading platform 310. The output end of the driving assembly 330 is transmission-connected with the slider 320. The driving assembly 330 is used to drive the slider 320 to move along the first direction X to transfer the loading assembly 030 located on the loading and unloading assembly 300.

[0067] Optionally, the loading and unloading platforms 310 are respectively provided with driving slots 311 extending along the first direction X corresponding to the driving components 330 , the slider 320 is slidably provided in the driving slots 311 , and the driving components 330 drive the slider 320 to move along the first direction X along the driving slots 311 .

[0068] Optionally, the drive assembly 330 includes at least two, two drive assemblies 330 are arranged in parallel, and two sliders 320 corresponding to the two drive assemblies 330 are also arranged; at the same time, the loading and unloading platform 310 is respectively provided with two drive grooves 311 extending along the first direction X corresponding to the two drive assemblies 330, and the two drive grooves 311 are arranged in parallel.

[0069] Optionally, the driving assembly 330 includes a threaded shaft 331 and a second driving member 332, the shaft 331 passes through the driving slot 311 along the first direction X, and the shaft 331 is threadedly connected to the driving body 220, one end of the shaft 331 is connected to the slider 320, and the other end is connected to the second driving member 332.

[0070] The second driving member 332 may be a handle, and the operator may manually rotate the handle to drive the shaft 331 to rotate relative to the driving body 220 , thereby driving the slider 320 to move along the first direction X.

[0071] The second driving member 332 may be a rotary motor, which may drive the shaft 331 to rotate, so that the shaft 331 rotates relative to the driving body 220 , thereby driving the slider 320 to move along the first direction X.

[0072] When the drive assemblies 330 include at least two, the two drive members located outside the loading and unloading platform 310 are further sleeved with shaft sleeves 333, and a transmission belt 334 is further sleeved between the two shaft sleeves 333. This arrangement allows the two drive assemblies 330 to assist each other in driving the slider 320.

[0073] Optionally, the loading and unloading platform 310 is further provided with a plurality of rolling devices 312, which can be arranged as needed. The rolling devices 312 are used to support the cargo and reduce the resistance of the loading assembly 030 during movement. Optionally, the rolling devices 312 are flexibly rotatable balls. The use of balls in the rolling devices 312 has a simple structure and good stability.

[0074] Alternatively, see Figure 9 The loading and unloading platform 310 is further provided with a first limiting protrusion 313 and a second limiting protrusion 314. The first limiting protrusion 313 extends along the first direction X and is disposed along the second direction Y on a side of the loading and unloading platform 310 away from the cabin opening 021. The second limiting protrusion 314 extends along the second direction Y and is disposed along the first direction X on a side of the loading and unloading platform 310 away from the airdrop cargo system 022. It will be appreciated that the first limiting protrusion 313 and the second limiting protrusion 314 can limit the loading assembly 030 to prevent it from leaving the loading and unloading platform 310.

[0075] In this embodiment, the height and width of the loading and unloading assembly 300 are adjustable, so that the loading and unloading assembly 300 can be adjusted in height and locked, and can be adapted to airdrop cargo systems 022 of different heights.

[0076] In this embodiment, the width of the loading and unloading assembly 300 can be adaptively set according to the width of the specific airdrop cargo system 022.

[0077] In this embodiment, please refer to Figure 10-11 The loading and unloading assembly 300 also includes a height adjustment structure 340, which includes a base 341, a first support arm 342, a second support arm 343 and an adjusting member 344. The base 341 is arranged at the bottom of the loading and unloading platform 310, and the first support arm 342 and the second support arm 343 are arranged at intervals between the base 341 and the loading and unloading platform 310; one end of the first support arm 342 is rotatably connected to the base 341, and the other end is rotatably connected to the loading and unloading platform 310; one end of the second support arm 343 is rotatably connected to the base 341, and the other end is rotatably connected to the loading and unloading platform 310.

[0078] One end of the adjusting member 344 is rotatably connected to the first supporting arm 342 , and the other end is rotatably connected to the second supporting arm 343 . The length of the adjusting member 344 is adjustable.

[0079] The base 341 and the loading and unloading platform 310 can be rotatably connected to the first support arm 342 and the second support arm 343 by hinges.

[0080] It is understood that the adjusting member 344 is adjusted according to the height of the airdrop cargo system 022 so that the loading and unloading platform 310 of the loading and unloading assembly 300 can dock with the airdrop cargo system 022. When the adjusting member 344 is lengthened, the first support arm 342 and the second support arm 343 rotate toward each other under the position limit of the adjusting member 344, so that the loading and unloading platform 310 moves toward the base 341, i.e., the height of the loading and unloading platform 310 is lowered. When the adjusting member 344 is shortened, the first support arm 342 and the second support arm 343 rotate toward the center under the position limit of the adjusting member 344, so that the loading and unloading platform 310 moves toward the side away from the base 341, i.e., the height of the loading and unloading platform 310 is raised.

[0081] Alternatively, see Figure 10-11 The adjusting member 344 includes a first adjusting rod 3441, a sleeve 3442 and a second adjusting rod 3443. One end of the first adjusting rod 3441 is rotatably connected to the first support arm 342, and the other end is threadedly connected to the sleeve 3442; one end of the second adjusting rod 3443 is rotatably connected to the second support arm 343, and the other end is movably connected to the sleeve 3442; the rotating connecting part 110 is used to adjust the length of the adjusting member 344.

[0082] Among them, the sleeve 3442 includes a pipe sleeve 3444 and a connecting block 3445, and the connecting block 3445 is connected to the pipe sleeve 3444; the connecting block 3445 is provided with a threaded opening, and the other end of the first adjusting rod 3441 is threadedly connected to the opening of the connecting block 3445; the other end of the second adjusting rod 3443 is movably connected to the pipe sleeve 3444.

[0083] The first adjusting rod 3441 , the sleeve 3442 and the second adjusting rod 3443 are coaxially arranged.

[0084] It can be understood that, when the sleeve 3442 is rotated along the first rotation direction, part of the first adjusting rod 3441 moves into the cavity of the sleeve 3444, the length of the first adjusting rod 3441 becomes shorter, and the length of the adjusting member 344 is shortened; when the sleeve 3442 is rotated along the second rotation direction, part of the first adjusting rod 3441 moves out of the cavity of the sleeve 3444, the length of the first adjusting rod 3441 becomes longer, and the length of the adjusting member 344 is lengthened; wherein, the first rotation direction and the second rotation direction are opposite.

[0085] It is worth mentioning that, since aircraft 010 has different parking angles when parked on the ground, namely, the angle formed between cabin 020 and the ground, when transfer assembly 200 loads loading assembly 030 into airdrop cargo system 022, in order to prevent the cargo in loading assembly 030 from tilting upon entry, it is necessary to keep the cargo in loading assembly 030 approximately parallel to the floor of cabin 020 during the transfer process, even if loading assembly 030 as a whole forms an attitude angle 035 relative to the ground. The attitude angle 035 of loading assembly 030 is specifically set according to the parking angle of aircraft 010.

[0086] Therefore, in this embodiment, when the transfer assembly 200 loads and unloads the loading assembly 030 , the attitude angle 035 of the loading assembly 030 relative to the ground can be adjusted so that the loading assembly 030 remains relatively parallel to the ground of the cabin 020 .

[0087] In this embodiment, the loading assembly 030 is provided with a through slot 031 that passes through the loading assembly 030 along a first direction X. The auxiliary loading and unloading system 040 includes a connector 100 having connecting portions 110 at both ends thereof, which passes through the through slot 031 of the loading assembly 030. A transfer assembly 200 is movably disposed on the ground and used to transfer the loading assembly 030. The transfer assembly 200 is provided with two lifting arms 210 that are movable along a third direction Z. The two lifting arms 210 are disposed along a second direction Y and spaced apart along the first direction X. The connecting portions 110 at both ends of the connector 100 are respectively connected to the two lifting arms 210.

[0088] It can be understood that when the transfer component 200 loads the loading component 030 on the airdrop cargo system 022, the two lifting arms 210 of the transfer component 200 lift the loading component 030 through the connecting piece 100, and the transfer component 200 adjusts the two lifting arms 210 along the third direction Z according to the position of the cabin 020, and the transfer component 200 transfers the loading component 030 into the cabin 020.

[0089] Among them, when the transfer component 200 unloads the loading component 030 on the airdrop cargo system 022, the transfer component 200 adjusts the two lifting arms 210 along the third direction Z according to the position of the loading component 030 in the cabin 020, and passes the connecting piece 100 through the through groove 031 of the loading component 030. The two lifting arms 210 of the transfer component 200 are respectively connected to the connecting parts 110 at both ends of the connecting piece 100 and the two lifting arms 210, and the transfer component 200 moves the loading component 030 out of the cabin 020.

[0090] As can be seen from the above, the present application sets up a transfer component 200, and the transfer component 200 is used to unload the loading component 030 on the airdrop cargo system 022 or load the airdrop cargo system 022 with the loading component 030. The two lifting arms 210 can cooperate with the cabin 020 of different heights to move along the third direction Z, and can conveniently and accurately load and unload the loading component 030; by setting up a connecting piece 100, the two lifting arms 210 of the transfer component 200 lift the loading component 030 through the connecting piece 100, and the loading component 030 is transferred through the lifting mode, and the lifting attitude angle 035 of the loading component 030 can be conveniently adjusted, and can adapt to various parking angles of the aircraft 010, so as to facilitate the loading and unloading of the loading component 030.

[0091] In this embodiment, the auxiliary loading and unloading system 040 includes a loading assembly 030 .

[0092] Please refer to Figure 3-Figure 4 , loading component 030 is used to load cargo.

[0093] In this embodiment, please refer to Figure 3-Figure 4 The loading assembly 030 includes a box body 032 with goods inside and a cargo platform 033.

[0117] It can be understood that the transfer assembly 200 is moved to the target position by operating the operating end 221 to operate the moving direction of the main body 220; wherein, the first driving member 230 drives the sliders 320 at both ends of the connecting rod 211 to move along the two guide grooves 241 in the third direction Z, thereby realizing the first driving member 230 driving the two lifting arms 210 to move along the third direction Z, thereby completing the lifting of the cargo from the ground to the loading and unloading assembly 300 or completing the lifting of the cargo loading and unloading assembly 300 to the ground.

[0118] The working principle and process of the auxiliary loading and unloading system 040 provided in the embodiment of the present invention are as follows:

[0119] 1. When transferring loading component 030 to airdrop cargo system 022, the ground cargo is transferred to airdrop cargo system 022:

[0120] Fix the loading and unloading assembly 300 in the cabin 020, and adjust the adjustment part 344 according to the height of the airdrop cargo system 022 so that the loading and unloading platform 310 of the loading and unloading assembly 300 can be docked with the input end of the airdrop cargo system 022.

[0121] Before loading, adjust the attitude angle 035 of the loading assembly 030 according to the parking angle of the aircraft 010. Please refer to Figure 3 ; Pass the connecting piece 100 through the through slot 031 of the loading assembly 030, adjust the length of the connecting piece 100 on both sides of the connecting piece 100 according to the attitude angle 035 of the loading assembly 030, and fix the limit piece 120 on the connecting piece 100. The loader operates the transfer assembly 200 through the operating end 221, raises and lowers the lifting arm 210 to the height flush with the connecting part 110, and inserts the two lifting arms 210 into the connecting holes 111 of the two connecting parts 110, please refer to Figure 6 The loader operates the control end 221 to control the moving direction of the main body 220 and moves the transfer assembly 200 to the hatch position. Hoist the loading assembly 030 to the top of the loading and unloading platform 310 and place it on the device platform. Please refer to Figure 2The loader operates the manipulator end 221 to move the loading and unloading assembly 300 and the lifting arm 210 out of the hatch position and removes the connecting member 100 from the through-slot 031 of the loading assembly 030.

[0122] Please refer to Figure 8 The loader operates the second driving member 332 to drive the slider 320 to drive the loading assembly 030 to move along the first direction X until the loading assembly 030 completely enters the airdrop cargo system 022. The airdrop cargo system 022 closes the limit lock on the loading assembly 030, and the cargo loading is completed.

[0123] 2. When unloading the loading component 030 on the airdrop cargo system 022, the cargo on the airdrop cargo system 022 is transferred to the ground:

[0124] The loading and unloading assembly 300 is fixed in the cabin 020, and the output end of the loading and unloading assembly 300 is connected to the input end of the airdrop cargo system 022. The airdrop cargo system 022 unlocks the limit lock on the loading assembly 030 and drives the loading assembly 030 to the loading and unloading platform 310.

[0125] Before loading, the connector 100 is passed through the through slot 031 of the loading assembly 030. The length of the connector 100 on both sides of the connector 100 is adjusted according to the attitude angle 035 of the loading assembly 030, and the stopper 120 is fixed to the connector 100. The loader uses the control end 221 to operate the transfer assembly 200, raising and lowering the lifting arm 210 to a height flush with the connecting portion 110. The two lifting arms 210 are inserted into the connection holes 111 of the two connecting portions 110 to lift the loading assembly 030. The loader manipulates the control end 221 to control the movement direction of the main body 220, moving the transfer assembly 200 to the ground.

[0126] In summary, the aircraft 010 provided in the embodiment of the present invention is different from the prior art that uses a conveyor belt to load and unload cargo. This application separates the transfer component 200 for transfer on the ground and the loading and unloading component 300 for transfer in the cabin 020. The loading and unloading component 300 can be detachably fixed in the cabin 020 according to loading requirements. The loading and unloading component 300 is fixed in the cabin 020, and the output end of the loading and unloading component 300 can be reliably docked with the input end of the airdrop cargo system 022. There is no need to consider the parking angle of the aircraft 010, and the cargo can be accurately loaded. At the same time, the height and width of the loading and unloading component 300 are adjustable, and the loading and unloading component 300 can be adjusted and locked in height to adapt to airdrop cargo systems 022 of different heights.

[0127] Furthermore, by setting up a transfer component 200, the transfer component 200 is used to unload the loading component 030 on the airdrop cargo system 022 or load the airdrop cargo system 022 with the loading component 030. The two lifting arms 210 can cooperate with the cabin 020 of different heights to move along the third direction Z, and can conveniently and accurately load and unload the loading component 030; by setting up a connecting piece 100, the two lifting arms 210 of the transfer component 200 lift the loading component 030 through the connecting piece 100, and the loading component 030 is transferred through the lifting mode, and the attitude angle 035 and the lifting attitude of the loading component 030 can be conveniently adjusted, and can adapt to various parking angles of the aircraft 010, so as to facilitate loading and unloading of the loading component 030.

[0128] Furthermore, by setting a limit member 120, when the transfer component 200 lifts the loading component 030 through the connecting member 100, the limit member 120 is fixedly connected to the connecting member 100 and is limitedly connected to the loading component 030, which can fix the loading component 030 that is currently at the posture angle 035, thereby preventing the loading component 030 from shaking due to external forces or sliding due to the shift of the center of gravity, thereby ensuring the stability of the posture of the loading component 030.

[0129] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or replacements that can be easily conceived by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
