[0047] The following describes in detail the overall structure, working principle, and technical effects of the auxiliary loading and unloading system 040 and aircraft 010 provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0048] Please refer to Figures 1-2 The auxiliary loading and unloading system 040 provided by this utility model is used by the airdrop cargo system 022 on the aircraft 010 to load or unload the loading component 030.

[0049] Please refer to Figures 1-2 The present invention provides an aircraft 010, comprising:

[0050] Auxiliary loading and unloading system 040;

[0051] Cabin 020, which contains an airdrop cargo system 022, used to load and airdrop loading components 030.

[0052] Optionally, aircraft 010 can be a fixed-wing large cargo drone, cargo plane, etc.

[0053] Among them, aircraft 010 also has a hatch 021 for loading and unloading loading components 030, and a hatch is connected to the hatch 021.

[0054] Please refer to Figures 1-2 This utility model provides an auxiliary loading and unloading system 040 for assisting in loading and unloading a loading assembly 030 loaded with goods. The loading assembly 030 is provided with a through groove 031, which penetrates the loading assembly 030 along a first direction X. The auxiliary loading and unloading system 040 includes:

[0055] The connector 100 has connecting portions 110 at both ends and passes through the through slot 031 of the loading assembly 030.

[0056] The transfer assembly 200 is movably mounted 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 arranged along a second direction Y and spaced apart along a first direction X. The connecting parts 110 at both ends of the connector 100 are respectively connected to the two lifting arms 210. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0057] When the transfer component 200 loads the loading component 030 onto the airdrop cargo system 022, the two lifting arms 210 of the transfer component 200 lift the loading component 030 through the connector 100. 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.

[0058] 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 connector 100 through the through slot 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 connector 100 and the two lifting arms 210 respectively. The transfer component 200 moves the loading component 030 out of the cabin 020.

[0059] Understandably, by setting up the transfer component 200, which is used to unload the loading component 030 on the airdrop cargo system 022 or to load the loading component 030 on the airdrop cargo system 022, the two lifting arms 210 can move along the third direction Z in coordination with the cabin 020 at different heights, enabling convenient and precise loading and unloading of the loading component 030; by setting up the connector 100, the two lifting arms 210 of the transfer component 200 lift the loading component 030 through the connector 100, and the loading component 030 is transferred by the lifting mode, which can easily adjust the lifting attitude of the loading component 030, can adapt to various parking angles of the aircraft 010, and facilitate the loading and unloading of the loading component 030.

[0060] 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.

[0061] In this embodiment, the auxiliary loading and unloading system 040 includes a loading component 030.

[0062] Please refer to Figures 3-4 Loading component 030 is used for loading goods.

[0063] In this embodiment, please refer to Figures 3-4 The loading assembly 030 includes a box 032 containing goods and a platform 033. The box 032 is fixedly connected to the top of the platform 033 along a third direction Z. A through groove 031 is provided at the bottom of the box 032 along a first direction X.

[0064] Optionally, the through slot 031 includes at least two, and at least two through slots 031 are provided at the bottom of the housing 032 along the first direction X, and at least two through slots 031 are provided at intervals along the second direction Y.

[0065] Optionally, the loading assembly 030 also includes a plurality of straps 034 for securing the container 032 to the top of the platform 033 along a third direction Z.

[0066] In this embodiment, the auxiliary loading and unloading system 040 includes a connector 100.

[0067] In this embodiment, please refer to Figures 4-5 The connector 100 has connecting portions 110 at both ends, and the connector 100 passes through the through slot 031 of the loading assembly 030.

[0068] The number of connecting parts 110 is the same as the number of through slots 031.

[0069] In this embodiment, please refer to Figure 5The connecting part 110 is provided with connecting holes 111, and the two lifting arms 210 respectively pass through the connecting holes 111 of the connecting parts 110 at both ends of the connector 100.

[0070] Of course, in other embodiments, the connecting part 110 can also be connected to the lifting arm 210 by means of binding or the like.

[0071] In one embodiment, please refer to Figure 5 The connector 100 includes a sling, and the connector 110 includes a lug with a connection hole 111. The sling and the two lugs are integrally formed.

[0072] In one embodiment, the connector 100 includes a sling, and the connector 110 includes hooks having connection holes 111, with the sling connected to two hooks.

[0073] It is worth mentioning that, due to the different parking angles of aircraft 010 when it is parked on the ground, i.e., the angle formed between the cabin 020 and the ground, the loading component 030 of the airdrop cargo system 022, when the transfer component 200 loads the loading component 030, needs to be kept approximately parallel to the floor of the cabin 020 during the transfer process to prevent the cargo inside the loading component 030 from tilting upon entry. This means the loading component 030 as a whole forms an attitude angle 035 with the ground. The attitude angle 035 of the loading component 030 is specifically set according to the parking angle of aircraft 010. Please refer to [reference needed]. Figure 3 When the transfer component 200 unloads the loading component 030 on the airdrop cargo system 022, it is necessary to keep the cargo stable and avoid the loading component 030 from swaying in the air, such as due to wind or the weight of the cargo.

[0074] In this embodiment, please refer to Figure 5 The connector 100 is provided with a limiting member 120, which is detachably connected to the connector 100. The limiting member 120 is limitedly connected to the loading component 030, and the limiting member 120 is used to stabilize the attitude of the loading component 030.

[0075] Understandably, please refer to Figure 3 and Figure 6 When the transfer component 200 lifts the loading component 030 through the connector 100, the limiting component 120 is fixedly connected to the connector 100 and limited to the loading component 030. This can fix the loading component 030, which is currently at an attitude angle of 035, to prevent the loading component 030 from shaking due to external forces or from sliding due to a shift in the center of gravity, thereby ensuring the stability of the attitude of the loading component 030.

[0076] In this embodiment, please refer to Figure 3 , Figure 5 and Figure 6 The limiting member 120 includes multiple fixing members 121, a first baffle 122 and a second baffle 123. The first baffle 122 is located above the connector 100 along the third direction Z, and the second baffle 123 is located below the connector 100 along the third direction Z. The multiple fixing members 121 sequentially fix the first baffle 122, the connector 100 and the second baffle 123 along the third direction Z. The first baffle 122 is also provided with a protrusion 1221 arranged along the third direction Z. The protrusion 1221 is limitedly connected to the loading assembly 030.

[0077] The protrusion 1221 should be located on the side near the bottom surface so that the protrusion 1221 can limit the loading component 030 in the hoisting state.

[0078] Optionally, the fastener 121 can be a fixing nail, etc.

[0079] Understandably, when the transfer assembly 200 transfers the loading assembly 030, the lengths of the connecting pieces 100 on both sides of the loading assembly 030 can be adjusted according to the stopping angle of the aircraft 010. After determining the lengths of the connecting pieces 100 on both sides of the loading assembly 030, the first baffle 122 and the second baffle 123 are fixed to the connecting pieces 100 by multiple fasteners 121, while ensuring that the protrusion 1221 is positioned on the side closest to the bottom surface. After the limiting piece 120 is installed, the transfer assembly 200 lifts the loading assembly 030 through the connecting pieces 100 to keep the loading assembly 030 stably tilted in the lifting state, thereby ensuring that the cargo inside the loading assembly 030 remains approximately parallel to the floor of the cabin 020 during the transfer process.

[0080] In this embodiment, the auxiliary loading and unloading system 040 includes a transfer component 200.

[0081] The transfer component 200 is used to transfer the loading component 030. The transfer component 200 is movably set on the ground.

[0082] In this embodiment, please refer to Figures 6-7 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 arranged along a second direction Y and spaced apart along a first direction X. The connecting portions 110 at both ends of the connector 100 are respectively connected to the two lifting arms 210.

[0083] In this embodiment, please refer to Figures 6-7The transfer assembly 200 includes a body 220, a first drive member 230, and two guide parts 240. The body 220 is movably mounted on the ground. The two ends of the body 220 along the second direction Y are respectively provided with an operating end 221 and two guide parts 240. The two guide parts 240 are spaced apart along the first direction X. Each guide part 240 is provided with a guide groove 241 along the third direction Z. The first drive member 230 is disposed between the two guide parts 240. The first drive member 230 is connected to the body 220. The output end of the first drive member 230 is drivenly connected to a connecting rod 211 along the first direction X. The two ends of the connecting rod 211 are respectively connected to two lifting arms 210. The two ends of the connecting rod 211 are also slidably connected to the two guide grooves 241. The first drive member 230 is used to drive the two lifting arms 210 to move along the third direction Z.

[0084] Optionally, the bottom of the main body 220 is provided with at least two roller structures 222, and the roller structures 222 and the operating end 221 are disposed on opposite sides of the main body 220, and the main body 220 can move on the ground through the roller structures 222.

[0085] Optionally, the first driving component 230 can be a motor, and the output end of the motor is provided with an output shaft 231, which is connected to the middle part of the connecting rod 211.

[0086] Optionally, the two ends of the connecting rod 211 are provided with pulleys 212, and the two pulleys 212 are respectively engaged and slidably disposed in the two guide grooves 241.

[0087] It is understandable that the movement direction of the main body 220 is operated by manipulating the control end 221, and the transfer component 200 is moved to the target position; wherein, the first drive 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 that the first drive member 230 drives the two lifting arms 210 to move along the third direction Z, thereby completing the lifting and lowering of the goods from the ground to the loading and unloading component 300 or completing the lifting and lowering of the loading and unloading component 300 to the ground.

[0088] In this embodiment, the auxiliary loading and unloading system 040 includes a loading and unloading component 300.

[0089] The loading and unloading assembly 300 is used to transfer the loading assembly 030 located on the loading and unloading assembly 300 to the airdrop cargo system 022.

[0090] In this embodiment, please refer to Figure 8The loading and unloading assembly 300 is detachably installed inside the cabin 020. The loading and unloading assembly 300 is docked with the airdrop cargo system 022, and the output end of the loading and unloading assembly 300 is connected to the input end of the airdrop cargo system 022. The transfer assembly 200 is used to transfer the loading assembly 030 to the loading and unloading assembly 300 and to transfer the loading assembly 030 located on the loading and unloading assembly 300.

[0091] Understandably, by separating the transfer component 200 that is transferred on the ground and the loading and unloading component 300 that is transferred in the cabin 020, the loading and unloading component 300 can be detachably fixed in the airport according to the loading requirements. The output end of the loading and unloading component 300 can reliably connect with the input end of the airdrop cargo system 022 without considering the stopping angle of the aircraft 010, and can complete the precise loading of cargo.

[0092] In this embodiment, please refer to Figures 8-9 The loading and unloading assembly 300 includes a loading and unloading platform 310, a slider 320, and a drive assembly 330. The loading and unloading platform 310 is detachably installed in the cabin 020 and docks with the airdrop cargo system 022 along the first direction X. The slider 320 is slidably installed on the loading and unloading platform 310 along the first direction X. The drive assembly 330 is installed on the loading and unloading platform 310. The output end of the drive assembly 330 is connected to the slider 320 for transmission. The drive 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.

[0093] Optionally, the loading and unloading platform 310 is respectively provided with a drive groove 311 extending along the first direction X for the drive component 330, and the slider 320 is slidably disposed in the drive groove 311. The drive component 330 drives the slider 320 to move along the first direction X along the drive groove 311.

[0094] Optionally, the drive assembly 330 includes at least two, the two drive assemblies 330 are arranged in parallel, and two sliders 320 are also provided corresponding to the two drive assemblies 330; at the same time, the loading and unloading platform 310 is provided with two drive slots 311 extending along the first direction X corresponding to the two drive assemblies 330 respectively, and the two drive slots 311 are arranged in parallel.

[0095] Optionally, the drive assembly 330 includes a threaded shaft 331 and a second drive member 332. The shaft 331 passes through the drive groove 311 along the first direction X and is threadedly connected to the drive body 220. One end of the shaft 331 is connected to the slider 320, and the other end is connected to the second drive member 332.

[0096] The second driving component 332 can be a handle. The operator can 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.

[0097] The second driving component 332 can be a rotary motor, which can 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.

[0098] When the drive assembly 330 includes at least two components, bushings 333 are also fitted onto the two drive components located outside the loading / unloading platform 310, and a transmission belt 334 is fitted between the two bushings 333. This arrangement allows the two drive assemblies 330 to mutually assist and drive the slider 320.

[0099] Optionally, the loading and unloading platform 310 is also equipped with multiple rolling devices 312. The multiple rolling devices 312 can be arranged as needed. The rolling devices 312 are used to support the goods and reduce the resistance of the loading assembly 030 during movement. Optionally, the rolling devices 312 are flexible rotating balls. The rolling devices 312 use balls, which have a simple structure and good stability.

[0100] Alternatively, please refer to Figure 9 The loading / unloading platform 310 is also provided with a first limiting protrusion 313 and a second limiting protrusion 314. The first limiting protrusion 313 extends along a first direction X and is located along a second direction Y on the side of the loading / unloading platform 310 away from the aircraft hatch 021. The second limiting protrusion 314 extends along the second direction Y and is located along the first direction X on the side of the loading / unloading platform 310 away from the airdrop cargo system 022. It can be understood that the first limiting protrusion 313 and the second limiting protrusion 314 can limit the loading component 030, preventing it from detaching from the loading / unloading platform 310.

[0101] The working principle and process of the auxiliary loading and unloading system 040 provided in this embodiment of the utility model are as follows:

[0102] 1. When transferring loading components 030 to the airdrop cargo system 022, that is, transferring ground cargo to the airdrop cargo system 022:

Figure 3The connector 100 is passed through the through slot 031 of the loading assembly 030. The lengths of the connectors 100 on both sides are adjusted according to the attitude angle 035 of the loading assembly 030, and the limiting member 120 is fixed on the connector 100. The loader operates the transfer assembly 200 through the control terminal 221 to raise and lower the lifting arm 210 to a 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 stevedore operates the control terminal 221 to control the movement direction of the main body 220, moving the transfer assembly 200 to the hatch position. The loading assembly 030 is then hoisted onto the top of the loading / unloading platform 310 and placed on the equipment platform. Please refer to... Figure 2 The loader operates the control terminal 221 to remove the loading and unloading assembly 300 and the hoisting arm 210 from the hatch position and takes out the connector 100 in the through slot 031 of the loading assembly 030.

[0105] Please refer to Figure 8 The loader operates the second drive component 332, which drives the slider 320 to move the loading component 030 along the first direction X until the loading component 030 is fully inside the airdrop cargo system 022. The airdrop cargo system 022 closes the limit lock on the loading component 030, thus completing the cargo loading.

[0106] 2. During the unloading of loading component 030 on the airdrop cargo system 022, the cargo on the airdrop cargo system 022 shall be transferred to the ground:

[0107] The loading / unloading assembly 300 is secured inside the cabin 020, and its output is connected to the input 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 onto the loading / unloading platform 310.

[0108] Before loading, the connector 100 is passed through the through slot 031 of the loading assembly 030. The lengths of the connectors 100 on both sides are adjusted according to the attitude angle 035 of the loading assembly 030, and the limiting member 120 is fixed on the connector 100. The loader operates the transfer assembly 200 through the control terminal 221 to raise and lower the lifting arm 210 to the same height as the connecting part 110, and inserts the two lifting arms 210 into the connecting holes 111 of the two connecting parts 110 to lift the loading assembly 030. The loader operates the control terminal 221 to control the movement direction of the main body 220 and move the transfer assembly 200 to the ground.

[0109] In summary, the auxiliary loading and unloading system 040 and aircraft 010 provided in this embodiment of the present invention, by setting up a transfer component 200, which is used to unload the loading component 030 on the airdrop cargo system 022 or to load the loading component 030 on the airdrop cargo system 022, and the two lifting arms 210 can move along the third direction Z to cooperate with the cabin 020 at different heights, so as to conveniently and accurately load and unload the loading component 030; by setting up a connector 100, the two lifting arms 210 of the transfer component 200 lift the loading component 030 through the connector 100, and the loading component 030 is transferred by the lifting mode, which can conveniently adjust the lifting attitude of the loading component 030, adapt to various parking angles of the aircraft 010, and facilitate the loading and unloading of the loading component 030.

[0110] Furthermore, by separating the transfer component 200 that is transferred on the ground and the loading and unloading component 300 that is transferred in the cabin 020, the loading and unloading component 300 can be detachably fixed in the airport according to the loading requirements. The output end of the loading and unloading component 300 can reliably connect with the input end of the airdrop cargo system 022 without considering the stopping angle of the aircraft 010, and can complete the precise loading of cargo.

[0111] Furthermore, by setting a limiting component 120, when the transfer component 200 hoists the loading component 030 through the connector 100, the limiting component 120 is fixedly connected to the connector 100 and limited to the loading component 030. This can fix the loading component 030, which is currently at an attitude angle of 035, and prevent the loading component 030 from shaking due to external forces or from sliding due to a shift in the center of gravity, thereby ensuring the attitude stability of the loading component 030.

[0112] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
