[0103] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0104] Figures 1 to 3 As shown, the aircraft cargo hold 1 of this embodiment includes a cargo hold body 100, a guiding mechanism 200, a movement limiting mechanism 300, and a fastening mechanism 400. The cargo hold body 100 is used to accommodate cargo 10, and the guiding mechanism 200, the movement limiting mechanism 300, and the fastening mechanism 400 are connected to the cargo hold body 100. The guiding mechanism 200 is used to guide the cargo 10 to move along a first direction D1 within the cargo hold body 100, and to limit the movement of the cargo 10 along a second direction D2. The movement limiting mechanism 300 is used to limit the movement of the cargo 10 along the first direction D1. The fastening mechanism 400 is used to limit the movement of the cargo 10 along a third direction D3. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other.

[0105] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to such processes, methods, products, or devices.

[0106] like Figure 1 and Figure 3 As shown, the cargo hold body 100 is a slender hollow structure. The length of the cargo hold body 100 extends along the first direction D1, the width of the cargo hold body 100 extends along the second direction D2, and the height of the cargo hold body 100 extends along the third direction D3.

[0107] The cargo hold body 100 has a receiving cavity 110 for accommodating cargo 10. It is understood that one or more cargoes 10 can be loaded in the receiving cavity 110. Each cargo 10 is a box-type or container-type cargo. When multiple cargoes 10 are loaded in the receiving cavity 110, the multiple cargoes 10 are arranged side by side along a first direction D1.

[0108] The cargo hold body 100 has a first end 101 and a second end 102 arranged opposite to each other in the first direction D1. The first end 101 and / or the second end 102 are provided with a hatch 120, which communicates with the receiving cavity 110. Through the hatch 120, cargo 10 can enter and exit the receiving cavity 110 of the cargo hold body 100.

[0109] It is understandable that the hatch door 120 can be located at the first end 101 of the cargo hold body 100; the hatch door 120 can also be located at the second end 102 of the cargo hold body 100; or, both the first end 101 and the second end 102 of the cargo hold body 100 can be provided with hatch doors 120.

[0110] In this embodiment of the invention, a hatch 120 is provided at the second end 102 of the cargo hold body 100.

[0111] like Figure 4 and Figure 5 As shown, the guide mechanism 200 is disposed in the receiving cavity 110, for guiding the goods 10 to move in the receiving cavity 110 along the first direction D1, and for restricting the goods 10 from moving along the second direction D2.

[0112] The guiding mechanism 200 includes a pair of guide rails 210 and at least one set of guide wheel assemblies 220. The pair of guide rails 210 are arranged parallel to each other within the receiving cavity 110 and are positioned opposite each other along a second direction D2. Each guide rail 210 extends along a first direction D1 to guide the movement of the cargo 10 along the first direction D1. The two guide rails 210 are positioned opposite each other in the second direction D2 to restrict the movement of the cargo 10 in the second direction D2. At least one set of guide wheel assemblies 220 is located within the receiving cavity 110. Each guide wheel assembly 220 includes a plurality of rollers 221 arranged along the first direction D1. Each roller 221 is used for rolling contact with the bottom surface of the cargo 10, and the axis of rotation of each roller 221 is parallel to the second direction D2. The rollers 221 of the at least one set of guide wheel assemblies 220 are able to make rolling contact with the cargo 10, reducing the resistance during loading and unloading of the cargo 10.

[0113] Each guide rail 210 includes a first guide member 211 and a second guide member 212. The first guide member 211 is connected to the cargo hold body 100 and is located at the bottom of the cargo 10. The second guide member 212 is vertically connected to the first guide member 211 and is located on the side of the cargo 10.

[0114] The connection method between the first guide member 211 and the cargo hold body 100 is not particularly limited; for example, it can be achieved by bolts, riveting, welding, etc. When the cargo 10 moves along the first direction D1 within the receiving cavity 110 of the cargo hold body 100, the bottom surface of the cargo 10 rolls into contact with the roller 221, and a gap may exist between the bottom surface of the cargo 10 and the first guide member 211.

[0115] Two second guide members 212 of a pair of guide rails 210 are respectively provided on two opposite sides of the cargo 10 in the second direction D2, for restricting the movement of the cargo 10 in the second direction D2.

[0116] like Figure 6As shown, each roller 221 can be mounted on the cargo hold body 100 via the first bracket 230, and the roller 221 is rotatably connected to the first bracket 230.

[0117] like Figure 1 and Figure 2 As shown, a movement limiting mechanism 300 is provided at the hatch 120 of the cargo hold body 100 to restrict the movement of the cargo 10 along the first direction D1.

[0118] In this embodiment of the invention, there are two movement limiting mechanisms 300. One movement limiting mechanism 300 is disposed at the first end 101 of the cargo hold body 100, and the other movement limiting mechanism 300 is disposed at the second end 102 of the cargo hold body 100 (the hatch door 120 is disposed at the second end 102). The two movement limiting mechanisms 300 respectively abut against the two end faces of a plurality of side-by-side cargoes 10 along the first direction D1, for limiting the movement of the cargoes 10 along the first direction D1. Figure 3 As shown, if the accommodating cavity 110 of the cargo hold body 100 contains three cargoes 10, then the limiting mechanism 300 provided at the first end 101 abuts against the left end face of the leftmost cargo 10, and the limiting mechanism 300 provided at the second end 102 abuts against the right end face of the rightmost cargo 10.

[0119] Of course, it is understandable that the number of movement limiting mechanisms 300 can be one or more. When there is only one movement limiting mechanism 300, it is located at the hatch door 120. When there are three or more movement limiting mechanisms 300, two of them are located at the first end 101 and the second end 102 of the cargo hold body 100, respectively, and the remaining movement limiting mechanisms 300 can be located between the first end 101 and the second end 102 of the cargo hold body 100.

[0120] like Figure 7 and Figure 8 As shown, the cargo hold body 100 is also provided with a connecting guide rail 130, and the movement limiting mechanism 300 is movably connected to the connecting guide rail 130 in the first direction D1. In this way, the movement limiting mechanism 300 can be adjusted in the first direction D1 so that the movement limiting mechanism 300 can adapt to the loading of cargo 10 of different lengths or different quantities of cargo 10.

[0121] In this embodiment of the invention, the cargo hold body 100 includes multiple pairs of connecting guide rails 130. The two pairs of connecting guide rails 130 are arranged at intervals in the second direction D2, and the limiting mechanism 300 is movably connected to the two pairs of connecting guide rails 130.

[0122] It is understandable that the number of paired connecting guide rails 130 corresponds to the number of motion limiting mechanisms 300.

[0123] The connecting rail 130 can be connected to the cargo hold body 100 via the second bracket 150, but is not limited thereto.

[0124] like Figure 7 As shown, the movement limiting mechanism 300 includes a movement limiting member 310 and a locking assembly 320. The movement limiting member 310 is used to abut against the cargo 10, and is movably connected to the connecting rail 130 of the cargo hold body 100 in a first direction D1. The locking assembly 320 is used to lock the movement limiting member 310 in a set position on the connecting rail 130 of the cargo hold body 100.

[0125] In one embodiment, the limiting member 310 includes a limiting part 311 and a connecting part 312. The limiting part 311 is used to abut against the cargo 10, and the connecting part 312 is connected to the limiting part 311. The connecting part 312 is locked in a set position on the connecting guide rail 130 of the cargo compartment body 100 by a locking component 320.

[0126] like Figure 8 As shown, the connecting guide rail 130 is provided with a guide groove 140 extending along the first direction D1. The groove opening 141 of the guide groove 140 forms a plurality of limiting holes 142 and a plurality of stop holes 143. The plurality of limiting holes 142 and the plurality of stop holes 143 are arranged alternately along the first direction D1, and the limiting holes 142 and the stop holes 143 are connected.

[0127] It is understandable that the shape of the limiting hole 142 can be circular and the shape of the stop hole 143 can be rectangular, but it is not limited to these.

[0128] like Figures 9 to 11 As shown, the limiting member 310 has a first through hole 313 (obscured, indicated by dashed lines in the reference numerals), which penetrates the first side surface 314 of the limiting member 310 facing the connecting guide rail 130 and the second side surface 315 facing away from the connecting guide rail 130. In this embodiment of the invention, the connecting portion 312 of the limiting member 310 has a first side surface 314 on the side facing the connecting guide rail 130 and a second side surface 315 on the side facing away from the connecting guide rail 130. The first through hole 313 penetrates the first side surface 314 and the second side surface 315 of the connecting portion 312.

[0129] The locking assembly 320 includes a shaft 321, a locking member 322, and a first elastic member 323. The shaft 321 passes through a first through hole 313, and one end of the shaft 321 is movably disposed within a guide groove 140. The size of the limiting hole 142 is larger than the size of the stop hole 143, so that one end of the shaft 321 passes through the limiting hole 142 and exits the guide groove 140, and is stopped by the stop hole 143. The locking member 322 passes through the first through hole 313 and is used to insert into any one or more of the plurality of limiting holes 142. The first elastic member 323 provides elastic force to the shaft 321 and the locking member 322, so that the shaft 321 tends to disengage from the guide groove 140 and the locking member 322 tends to insert into the limiting hole 142.

[0130] When one end of the shaft 321 corresponds to the limiting hole 142, the shaft 321 can be inserted into the guide groove 140 through the limiting hole 142 and can be pulled out from the guide groove 140. When one end of the shaft 321 corresponds to the stop hole 143, if one end of the shaft 321 is already in the guide groove 140, the shaft 321 cannot be pulled out from the guide groove 140. If one end of the shaft 321 is outside the guide groove 140, the shaft 321 cannot be inserted into the guide groove 140 through the stop hole 143.

[0131] As an example, the first elastic element 323 can be a spring, which is sleeved on the outer periphery of the shaft 321, but is not limited thereto.

[0132] The shaft 321 includes a rod portion 321c and a first stop portion 321a and a second stop portion 321b disposed at both axial ends of the rod portion 321c. The rod portion 321c passes through a first through hole 313. The first stop portion 321a is disposed on a first side surface 314 and extends into a guide groove 140 through a limiting hole 142, and is movable along the guide groove 140. When the first stop portion 321a moves along the guide groove 140 to correspond to the stop hole 143, the first stop portion 321a cannot be pulled out of the guide groove 140 through the stop hole 143. The second stop portion 321b is disposed on a second side surface 315, and both ends of the first elastic member 323 abut against the second stop portion 321b and the locking member 322, respectively.

[0133] The locking member 322 includes an operating part 322a and an insertion part 322b. The operating part 322a is provided on the second side surface 315 and has a second through hole 322c corresponding to the first through hole 313. The shaft 321 passes through the first through hole 313 and the second through hole 322c. The insertion part 322b is connected to the operating part 322a and passes through the first through hole 313, and is used to insert into the limiting hole 142.

[0134] In this embodiment of the invention, the locking member 322 includes two insertion portions 322b, which are disposed on both sides of the shaft 321 in the first direction D1. The two insertion portions 322b are used to insert into two adjacent limiting holes 142.

[0135] As an example, the second stop portion 321b is screwed to the rod portion 321c. By screwing the second stop portion 321b to the rod portion 321c, the degree of compression of the first elastic member 323 by the second stop portion 321b can be adjusted, thereby adjusting the locking force of the locking assembly 320.

[0136] The following is combined Figures 9 to 11 The installation process of the limiting mechanism 300 is described in detail. The disassembly process of the limiting mechanism 300 is the reverse of the installation process, and will not be described here.

[0137] It should be noted that the distance between the two paired connecting rails 130 in the second direction D2 is approximately the same as the distance between the two first through holes 313 on the limiting member 310, so that the two locking components 320 are locked onto the two connecting rails 130 respectively.

[0138] like Figure 9 As shown, the first stop portion 321a of the two shafts 321 of the two locking components 320 is aligned with any one of the plurality of limiting holes 142, and inserted into the guide groove 140 through the limiting hole 142.

[0139] like Figure 10 As shown, the limiting member 310 is moved along the first direction D1 until it comes into contact with the cargo 10. During the movement of the limiting member 310, the locking member 322 can be pulled upward to prevent the insertion part 322b of the locking member 322 from being inserted into the limiting hole 142 and thus preventing the limiting member 310 from moving.

[0140] like Figure 11 As shown, the two insertion portions 322b of the locking member 322 are respectively inserted into two adjacent limiting holes 142, and the locking member 322 is released. Under the action of the elastic force provided by the first elastic member 323, the locking assembly 320 locks the limiting member 310 in the set position.

[0141] like Figure 12 As shown, the fastening mechanism 400 is connected to the cargo hold body 100 and is used to restrict the movement of the cargo 10 along the third direction D3.

[0142] The fastening mechanism 400 includes a fastening strap 410 connected to the cargo hold body 100. The fastening strap 410 includes a first connecting end 411, a second connecting end 412, and a fastening section 413. The first connecting end 411 is connected to the first end 101, the second connecting end 412 is connected to the second end 102, and the fastening section 413 is disposed between the first connecting end 411 and the second connecting end 412 for pressing against the top of the cargo 10 in the third direction D3.

[0143] In this embodiment of the invention, the fastening mechanism 400 includes two fastening bands 410, which are arranged at intervals along the second direction D2.

[0144] Of course, in other embodiments, the number of fastening straps 410 may be one or more, and there is no particular limitation on this.

[0145] In this embodiment of the invention, the first connecting end 411 of one fastening strap 410 is connected to one of the connecting guide rails 130 of the first end 101, and the second connecting end 412 of the fastening strap 410 is connected to one of the connecting guide rails 130 of the second end 102. The first connecting end 411 of another fastening strap 410 is connected to the other connecting guide rail 130 of the first end 101, and the second connecting end 412 of the fastening strap 410 is connected to the other connecting guide rail 130 of the second end 102.

[0146] The fastening mechanism 400 also includes a first connecting ring 414 and a second connecting ring 415. The first connecting end 411 is connected to the connecting guide rail 130 of the first end 101 through the first connecting ring 414, and the second connecting end 412 is connected to the connecting guide rail 130 of the second end 102 through the second connecting ring 415.

[0147] Return to reference Figure 7 Regarding the connection method between the first connecting ring 414 and the second connecting ring 415 and the connecting guide rail 130, they can be connected to the connecting guide rail 130 through a mechanism similar to the locking component 320 of the limiting mechanism 300, so that the first connecting ring 414 or the second connecting ring 415 can be movably installed on the connecting guide rail 130 along the first direction D1, which will not be described in detail here.

[0148] like Figure 13 As shown, the fastening mechanism 400 also includes a second elastic element 420, through which the fastening strap 410 is connected to the top of the cargo hold body 100. When the first connecting end 411 and the second connecting end 412 of the fastening strap 410 are released from the first connecting ring 414 and the second connecting ring 415, the second elastic element 420 can pull the fastening strap 410 upward so as not to affect the loading and unloading of the cargo 10.

[0149] As an example, the second elastic element 420 can be an elastic band, but is not limited thereto.

[0150] The following is combined Figures 14 to 16 The loading and unloading process of cargo 10 is described in detail.

[0151] I. Loading process of cargo 10

[0152] (1) Remove the movement limiting mechanism 300 located at the hatch 120 from the connecting guide rail 130 and lay the connecting ring flat to prevent the connecting ring from affecting the movement of the cargo 10. Under the action of the second elastic member 420, the fastening strap 410 can be held at the top of the cargo hold body 100 and will not affect the cargo 10 from entering the receiving cavity 110.

[0153] It should be noted that, since the hatch door 120 of the present invention is located at the second end 102 of the cargo hold body 100, while the first end 101 of the cargo hold body 100 is not provided with the hatch door 120, the first connecting end 411 of the fastening strap 410 can always be connected to the connecting ring. However, since the second connecting end 412 of the fastening strap 410 is located at the hatch door 120, it is necessary to remove the second connecting end 412 from the connecting ring during installation.

[0154] (2) Cargo 10 is pushed into the receiving cavity 110 of the cargo hold body 100 through the hatch 120. Two guide rails 210 are used to guide the cargo 10 to move along the first direction D1 until the cargo 10 moves to the first end 101 of the cargo hold body 100. At the same time, the two guide rails 210 are also used to restrict the movement of the cargo 10 in the second direction D2. During the movement of the cargo 10, rollers 221 support the movement of the cargo 10 to reduce the resistance to the movement of the cargo 10.

[0155] (3) After the cargo 10 is loaded, the movement limiting mechanism 300 is installed on the connecting rail 130 of the hatch 120 to limit the movement of the cargo 10 in the first direction D1. At the same time, the second connecting end 412 of the fastening strap 410 is connected to the connecting ring at the hatch 120 to fasten the cargo 10 in the third direction D3.

[0156] II. Unloading process of cargo 10

[0157] (1) Remove the movement limiting mechanism 300 at hatch door 120 and remove the second connecting end 412 of the fastening strap 410 from the connecting ring. At the same time, lay the connecting ring at hatch door 120 flat.

[0158] (2) Unloading is carried out one by one from the hatch 120. Two guide rails 210 are used to guide the cargo 10 to move along the second direction D2. Rollers 221 support the movement of the cargo 10 to reduce the resistance of the movement of the cargo 10.

[0159] (3) After the cargo 10 is unloaded, the motion limiting mechanism 300 is installed on the connecting guide rail 130 and restored to its initial position.
