Detailed Implementation

[0134] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant disclosure and not intended to limit the disclosure. The described embodiments are only a part of the embodiments of the present application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0135] See Figure 1Some embodiments of this application disclose a box assembly 1, including at least two boxes 11, which are stacked along a preset direction; a first limiting assembly 12 is provided between two adjacent boxes 11 arranged in a vertical direction, the first limiting assembly 12 including a first limiting part 121 and a second limiting part 122 that are paired with each other and have complementary shapes; wherein, the first limiting part 121 is provided at the bottom of one box 11, and the second limiting part 122 is provided at the top of the other box 11; when the two boxes 11 are stacked in a vertical direction, the first limiting part 121 and the second limiting part 122 are physically coupled to restrict the movement of at least two boxes 11 in the horizontal direction.

[0136] The first limiting part 121 and the second limiting part 122 of the box assembly 1 of this application form a precise physical coupling during loading. This coupling directly counteracts the lateral inertial force or impact force generated when the box assembly 1 moves horizontally, effectively preventing the box assembly 1 from slipping, swinging or rotating in the horizontal plane, thereby optimizing the stability of the box assembly 1 during transportation.

[0137] The preset direction can be either vertical or horizontal. Figure 1 The middle box assembly 1 includes 7 boxes 11, which are stacked vertically as a whole; the five boxes 11 in the middle are divided into two groups, one on the left and one on the right. Figure 1 The seven boxes 11 of the middle box assembly 1 correspond to four different sizes of boxes 11. Figure 2 The middle cabinet assembly 1 includes three cabinets 11, corresponding to three different sizes of cabinets 11: the first cabinet 11a, the second cabinet 11b, and the third cabinet 11c. For example, the first cabinet 11a is a 39-inch cabinet 11, the second cabinet 11b is an 18-inch cabinet 11, and the third cabinet 11c is an 11-inch cabinet 11. Figure 3 The middle cabinet assembly 1 includes seven cabinets 11, corresponding to four different sizes of cabinets 11, namely the first cabinet 11a, the second cabinet 11b, the third cabinet 11c, and the fourth cabinet 11d. For example, the first cabinet 11a is a 39-inch cabinet 11, the second cabinet 11b is an 18-inch cabinet 11, and the third cabinet 11c is an 11-inch cabinet 11.

[0138] When the preset direction includes the vertical direction, a first limiting component 12 is provided between two adjacent boxes 11 arranged in the vertical direction. The first limiting component 12 includes a first limiting part 121 and a second limiting part 122 that are paired with each other and have complementary shapes. The first limiting part 121 is located at the bottom of one box 11, and the second limiting part 122 is located at the top of the other box 11. When the two boxes 11 are stacked in the vertical direction, the physical coupling between the first limiting part 121 and the second limiting part 122 restricts the horizontal movement of the two boxes 11. In some embodiments, one of the first limiting part 121 and the second limiting part 122 is a protrusion, and the other is a recess adapted to the shape of the protrusion, and the two form an interlock to restrict horizontal movement; or both the first limiting part 121 and the second limiting part 122 are protrusions, and they restrict horizontal movement by abutting against each other.

[0139] The first limiting part 121 and the second limiting part 122 form a precise physical fit during loading. This fit directly counteracts the lateral inertial force or impact force generated between the boxes 11 when the trailer 2 moves, effectively preventing slippage, swaying, or rotation between the box components 1 in the horizontal plane, thereby optimizing the stability of the loading system, such as... Figure 23 As shown.

[0140] It should be noted that the recesses and protrusions on the box 11 can be extended and replicated indefinitely.

[0141] See Figure 5 and Figure 6 The housing assembly 1 also includes a locking assembly 13, which includes a first locking part 131 and a second locking part 132. The first locking part 131 is located at the bottom of one housing 11, and the second locking part 132 is located at the top of the other housing 11. The locking assembly 13 has a locked state and an unlocked state. When the locking assembly 13 is in the locked state, the first locking part 131 and the second locking part 132 are engaged together. Figure 6 As shown in (b); when the locking component 13 is in the unlocked state, the first locking part 131 and the second locking part 132 disengage and can disengage from each other as shown in (b). Figure 6 As shown in (a), when two boxes 11 are stacked vertically into place, the first locking part 131 and the second locking part 132 are aligned and can be switched to the locked state to restrict the movement of at least two boxes 11. By setting the locking component 13, the boxes 11 between adjacent layers in the vertical direction can be limited by the locking component 13 to limit the inertial force or impact force in the vertical direction of the box assembly 1 during transportation, thereby improving the stability of the box assembly 1 in the vertical direction.

[0142] See Figure 7 and Figure 8The first locking part 131 includes a connecting plate 1311 and a latch 1312. The latch 1312 is connected to the connecting plate 1311. The connecting plate 1311 is integrally formed with the housing 11 or connected by fasteners. Figure 7 The dimensions of the locking component 13 shown are smaller than those of the other component. Figure 8 The dimensions of the locking component 13 shown are for use with housings 11 of different sizes.

[0143] In the figure, the second locking part 132 includes a first locking member 1321 and a second locking member 1322. The second locking member 1322 slides with the first locking member 1321 to move between a locked position and an unlocked position. When the second locking part 132 is in the locked position, it can lock the first locking part 131. When the second locking part 132 is in the unlocked position, the first locking part 131 can disengage from the second locking part 132.

[0144] See Figures 9 to 11 The first locking member 1321 includes a first locking shell 13211, which has a sliding cavity 13211b and a latch 13211a. The second locking member 1322 includes a second locking shell 13221, a latch 13222, a first elastic member 13223, and a second elastic member 13224. The second locking shell 13221 is slidably disposed in the sliding cavity 13211b, and the latch 13222 is slidably disposed in the latch groove 13221a of the second locking shell 13221. The first elastic member 13223 is located between the sliding cavity 13211b and the second locking shell 13221 to drive the second locking member 1322 to be held in the locked position. The second elastic member 13224 is located between the latch groove 13221a and the latch 13222 to lock the latch tongue 1312.

[0145] The second locking member 1322 is connected to the first locking member 1321 by a snap-fit. Specifically, the second locking member 1322 also includes a first limiting arm 13225 disposed on the second locking shell 13221. The second locking member 1322 can be locked onto one side of the bayonet 13211a by the first limiting arm 13225 to prevent the second locking shell 13221 from disengaging from the first locking member 1321. When the second locking member 1322 needs to be installed into the first locking member 1321, the second locking shell 13221 is inserted into the sliding cavity 13211b. The first protrusion 13225a on the first limiting arm 13225 abuts against the cavity wall of the sliding cavity 13211b, and under its limiting action, the first limiting arm 13225 deforms to ensure that the second locking shell 13221 can move smoothly within the sliding cavity 13211b. When the housing 13221 is installed in place, the first protrusion 13225a of the first limiting arm 13225 is engaged at the slot 13211a, the second limiting arm 13226 is reset, and the second locking member 1322 is installed inside the first locking member 1321. When it is necessary to remove the second locking member 1322, press the first limiting arm 13225 to disengage the first protrusion 13225a from the slot 13211a, and then move the second locking housing 13221 outward. In addition, in some other embodiments of this application, the second locking member 1322 and the first locking member 1321 can also be connected by fasteners, such as screws, which will not be described in detail here.

[0146] To further improve the stability of the engagement between the second locking member 1322 and the first locking member 1321, the second locking member 1322 also includes a second limiting arm 13226 disposed on the second locking housing 13221. The first locking member 1321 is provided with a guide groove 13211c. The second locking member 1322 can be engaged with the groove wall of the guide groove 13211c by the second limiting arm 13226, thereby preventing the second locking housing 13221 from disengaging from the first locking housing 13211. When the second limiting arm 13226 abuts against one groove wall of the guide groove 13211c, the second locking part 132 is in the locked position; when the second limiting arm 13226 abuts against the other groove wall of the guide groove 13211c, the second locking part 132 is in the unlocked position. It should be noted that the second limiting arm 13226 is arranged parallel to the first limiting arm 13225.

[0147] When the second locking member 1322 needs to be installed into the first locking member 1321, the second locking shell 13221 is inserted into the sliding cavity 13211b. The second protrusion 13226a on the second limiting arm 13226 is lower than the cavity wall of the sliding cavity 13211b, and under its limiting action, the second limiting arm 13226 deforms to ensure that the second locking shell 13221 can move smoothly in the sliding cavity 13211b. When 3221 is installed in place, the second protrusion 13226a of the second limiting arm 13226 is engaged in the guide groove 13211c, the second limiting arm 13226 is reset, and the second locking member 1322 is installed in place inside the first locking member 1321. When it is necessary to remove the second locking member 1322, press the second limiting arm 13226 so that the second protrusion 13226a is disengaged from the guide groove 13211c, and the second locking shell 13221 can be moved outward.

[0148] The number of the second protrusion 13226a can be one or more. In the figure, there are two second protrusions 13226a, and there are also two corresponding guide slots 13211c.

[0149] The first locking part 131 and / or the second locking part 132 are detachably or non-detachably connected to the housing 11. See Figure 17 and Figure 18 , Figure 17 The first locking part 131 is detachably connected to the housing 11, for example, by screws. Figure 18 The second locking part 132 is detachably connected to the housing 11, for example, by snap-fit. Of course, the second locking part 132 can also be connected to the housing 11 by screws, and the first locking part 131 can also be snap-fitted to the housing 11, which will not be described in detail here.

[0150] When the second locking part 132 is engaged with the housing 11, see Figure 19 and Figure 20 The housing assembly 1 also includes a latch 133, and the second locking part 132 also includes a mounting slot 13227, wherein the latch 133 can be locked in the mounting slot 13227.

[0151] The latch 133 may include a first latch 1331 and a second latch 1332, wherein the first latch 1331 is formed on the housing 11 and the second latch 1332 is formed on the first latch 1331.

[0152] A first locking part 131 may be provided at the bottom of a housing 11, or multiple first locking parts 131 may be provided. When two first locking parts 131 are provided, they may be located at two adjacent corners or at two opposite corners. Similarly, a second locking part 132 may be provided at the top of a housing 11, or multiple second locking parts 132 may be provided. When two second locking parts 132 are provided, they may be located at two adjacent corners or at two opposite corners.

[0153] See Figure 21 Two first locking parts 131 are provided at the bottom of a box 11, and the two first locking parts 131 are located at two opposite corners of the box 11; two second locking parts 132 are provided at the top of a box 11, and the two second locking parts 132 are located at two opposite corners of the box 11.

[0154] In addition, for larger boxes 11, a first locking part 131 and a second locking part 132 can be provided in the middle.

[0155] Furthermore, to further improve the compatibility between the housing 11 and the trailer described below, a second locking part 132 may be provided at the corner of the trailer. This second locking part 132 has the same structure as the second locking part 132 described above, and the second locking part 132 is either detachably connected to the trailer or not detachably connected. The connection relationship between the second locking part 132 and the trailer can be referred to the connection relationship between the second locking part 132 and the housing 11, which will not be described in detail here.

[0156] See Figure 60 The box body 11 includes a lid lock 111, which is mounted on the box body 11 via a pivot 112. The lid lock 111 also includes a male buckle 321 that cooperates with the fixing component 3, as detailed below.

[0157] The housing 11 also includes a handle, which is mounted on the housing 11 via a fixing rib 113; both ends of the rotating shaft 112 are fixed to the fixing rib 113, and there is also an installation space for mounting the fixing component 3 between the fixing rib 113 and the housing cover lock 111.

[0158] See Figures 23 to 27 This application discloses a shipping system, including a container assembly 1 for loading goods and a trailer 2 for carrying and transferring the container assembly 1. Since the container assembly 1 has the above-mentioned beneficial effects, the shipping system including the container assembly 1 has the corresponding effects, which will not be described in detail here.

[0159] To optimize stability during container transport, a second limiting component 4 is provided between the bottom of the container assembly 1 and the support structure on the trailer 2 that supports the container assembly 1. The second limiting component 4 includes a third limiting part and a fourth limiting part 212. The third limiting part is located at the bottom of the container assembly 1, and the fourth limiting part 212 is located on the support structure. When the container assembly 1 is loaded onto the trailer 2, the third limiting part and the fourth limiting part 212 form a physical coupling to restrict the horizontal movement of the container assembly 1 relative to the trailer 2. The physical coupling between the third limiting part and the fourth limiting part 212 can be understood as one of the third limiting part and the fourth limiting part 212 being a protrusion and the other being a recess that matches the shape of the protrusion, forming a physical coupling through the interlocking of the protrusion and recess; or in some embodiments, the third limiting part and the fourth limiting part 212 limit each other by abutting, for example, both being protruding structures, and the horizontal movement is restricted by the abutting interlocking.

[0160] The third and fourth limiting parts 212 of the loading system of this application form a precise physical coupling during loading. This physical coupling directly counteracts the lateral inertial force or impact force generated when the trailer 2 moves, effectively preventing the box assembly 1 from slipping, swaying or rotating in the horizontal plane, thereby optimizing the stability of the loading system.

[0161] To optimize the above scheme and improve the versatility of the entire transfer system, each box 11 is provided with a first limiting part 121 at its bottom and a second limiting part 122 at its top. One of the third and fourth limiting parts 212 is protruding, which matches the shape of the recessed one of the first and second limiting parts 121; conversely, the recessed one of the third and fourth limiting parts 212 matches the shape of the protruding one of the first and second limiting parts 121. In other words, boxes 11 of any size and specification can be arranged on the support structure of the trailer 2 and cooperate with the fourth limiting part 212.

[0162] For example, the top of the box 11 is recessed, the bottom of the box 11 is raised, and the fourth limiting part 212 of the support structure is raised. Therefore, any box 11 placed on the support structure can cooperate with the third limiting part. It should be noted that the recesses and protrusions on the box 11 can be extended and replicated indefinitely.

[0163] See Figure 28 and Figure 29 The trailer 2 includes a frame 21, wheels 22 and a tie rod 23. The wheels 22 are located at the four corners of the frame 21. The support structure is located on the frame 21. The tie rod 23 is located on one end of the frame 21.

[0164] The frame 21 may include two opposing main support tubes 211, and four wheels 22 are respectively arranged at the front and rear ends of the two main support tubes 211, forming two wheels 22 at the front end and two wheels 22 at the rear end. The wheels 22 are arranged directly or indirectly on the main support tubes 211; in the illustration, the wheels 22 are arranged indirectly on the main support tubes 211. It should be noted that the wheels 22 can be swivel wheels or off-road mountain bike wheels to adapt to different usage scenarios. Figure 28 and Figure 29 The 22-wheeled vehicle is a swivel wheel, used for parallel transport of goods. Figure 30 The 22-wheeled vehicle is a large off-road mountain vehicle wheel, which can be used for cargo transport by tilting.

[0165] Combination Figure 28 and Figure 29 See Figure 31 The fourth limiting part 212 shown in the figure may include a support member 2121 and a limiting block 2122. The limiting block 2122 is disposed on the outer periphery of the support member 2121 to adapt to the third limiting part. The limiting block 2122 is directly connected to the support member 2121 or indirectly connected. In the indirect connection scheme, the limiting block 2122 is connected to the support member 2121 by fasteners 2123 and nuts 2124.

[0166] The limiting block 2122 can be made of rubber, plastic, metal, etc.

[0167] The aforementioned support component 2121 can be a pipe. The support component 2121 can be directly or indirectly connected to the main support pipe 211. In the direct connection method, it is connected to the main support pipe 211 by welding, riveting, or bolting. In the indirect connection method, the support component 2121 and the main support pipe 211 are connected by a connector.

[0168] For safety reasons, both ends of the support member 2121 are sealed with plugs 2125 to reduce the entry of dust and other debris into the support member 2121 and to block the sharp edges of the support member 2121.

[0169] To improve the connection strength of the frame 21, the frame 21 may also include a reinforcing tube 213, the two ends of which are connected to the main support tube 211 to improve the connection strength of the main support tube 211.

[0170] In addition, the frame 21 may also include two oppositely arranged fixed axles 214, one fixed axle 214 connecting the two front wheels 22 and the other fixed axle 214 connecting the two rear wheels 22.

[0171] The fixed shaft 214 can be directly or indirectly connected to the two wheels 22, for example, by connecting to the wheels 22 through the main support tube 211, or by connecting to the wheels 22 through the fastener 251 mentioned later.

[0172] For ease of transport, the frame 21 may also include a pull rod 23, which allows the trailer 2 to be moved. It should be noted that the number of pull rods 23 can be one or two. Figures 28 to 33 In the trailer 2 shown, there are two tie rods 23, each corresponding to a fixed shaft 214. (See also...) Figure 34 and Figure 36 The pull rod 23 includes a first position and a second position. When the pull rod 23 is in the first position, it forms a first angle with the frame 21 and is stored at the bottom of the frame 21. Figure 34 As shown; when the pull rod 23 is in the second position, the pull rod 23 and the frame 21 form a second angle, so as to push and pull the trailer 2, as shown. Figure 35 As shown. Since the lever 23 has two positions, the position of the lever 23 can be selected according to different usage scenarios, for example... Figure 25 and Figure 27 In the middle, both levers 23 are in the first position; as Figure 23 and Figure 26 In the middle, one of the levers 23 is in the first position, and the other lever 23 is in the second position.

[0173] Furthermore, to further expand the functionality of the trailer 2, the tie rod 23 also includes a third position. When the tie rod 23 is in the third position, it forms a third angle with the frame 21, and the two tie rods 23 can support the frame 21 on the ground. Figure 36 As shown.

[0174] See Figure 37 To accommodate different heights and transportation needs, the aforementioned pull rod 23 is a telescopic pull rod 23. Specifically, the pull rod 23 may include a first pull rod section 231 and a second pull rod section 232. The first pull rod section 231 is slidably located within the second pull rod section 232, and a pull rod lock 233 is located at the first pull rod section 231. The pull rod lock 233 is normally in a locked state, and the first pull rod section 231 is fixed relative to the second pull rod section 232. When the pull rod lock 233 is in an unlocked state, the first pull rod section 231 can move relative to the second pull rod section 232, that is, it can extend or shorten relative to the second pull rod section 232.

[0175] In some embodiments of this application, see [link to relevant documentation]. Figure 32 and Figure 33 The trailer 2 also includes a fixed panel 26, which is mounted on the frame 21 and forms a support structure. Figure 32The central tie rod 23 is in the first position, and the wheel 22 is a swivel wheel; Figure 33 The central tie rod 23 is in the first position, and the wheel 22 is a large off-road mountain bike wheel. The structure of the aforementioned fixed panel 26 is similar to the structure of the box cover 11, and it may be provided with a recess to match the protrusion at the bottom of the box 11; or it may be provided with a protrusion to match the recess at the bottom of the box 11. Figure 40 When the middle tie rod 23 is in the third position, the trailer 2 can be used as a bench.

[0176] A box 11 can also be mounted on the frame 21 for storing items, such as... Figure 38 and Figure 39 As shown. When the lid of the housing 11 is not open, the lid of the housing 11 can be used as a work panel, as shown. Figure 38 As shown. When the lid of the box 11 is open, the interior of the box 11 can be equipped with necessary components, such as a work board and storage compartments. Storage hanging panels can be installed on the inner surface of the lid. In this case, the structure can be used for applications such as picnics and displaying goods. Figure 39 As shown.

[0177] Display panels 24 can be arranged on the surface of the frame 21 to support people or objects, forming a structure that functions as a table or stool, such as... Figure 41 and Figure 42 As shown. The aforementioned display panel 24 can be a foldable structure, unfolded and laid flat on the frame 21 when in use, and folded together for easy storage when not in use. Alternatively, the aforementioned display panel 24 can be attached to the frame 21. See also Figures 43 to 45 The back of the display panel 24 includes a flexible arm 2422, which allows the display panel 24 to be detachably mounted on the reinforcing tube. The flexible arm 2422 is detachably connected to the display panel 24, for example, via a fastener 2421. To further improve the integrity between adjacent display panels 24, one side of each display panel 24 has a first overlapping portion 243, and the opposite side has a second overlapping portion 244. The first overlapping portion 243 has an overlapping hole. During assembly, the second overlapping portion 244 of the current display panel 24 is inserted into the overlapping hole of the first overlapping portion 243 of the previous display panel 24, and is secured to the outer periphery of the reinforcing tube by the flexible arm 2422, thereby completing the connection between the display panel 24 and the frame 21.

[0178] The position of the aforementioned tie rod 23 relative to the frame 21 can be adjusted by adjusting the rotation angle of the tie rod 23, or the tie rod 23 can be detachably connected to the fixed shaft 214, or the fixed shaft 214 can be detachably connected to the wheel 22, and the corresponding first included angle, second included angle, and third included angle can be adjusted by the detachable connection.

[0179] In some embodiments of this application, for ease of operation, the aforementioned pull rod 23 can be adjusted at the aforementioned included angle by rotation. Therefore, the trailer 2 may further include an angle adjustment component 25, which is used to control the pull rod 23 to be stably positioned in the first position, the second position, and the third position, such as... Figure 46 As shown.

[0180] Specifically, the angle adjustment assembly 25 includes a fixing member 251, an angle adjustment plate 252, an unlocking rod 253, and a tension spring 254. The fixing member 251 is arranged on the main support tube 211 of the frame 21 and includes a fixing groove 2511. The angle adjustment plate 252 is coaxially connected to the fixing shaft 214. The angle adjustment plate 252 includes three normal grooves 2521. The unlocking rod 253 passes through the pull rod 23 and can extend relative to the length direction of the pull rod 23. The unlocking rod 253 is connected to the fixing shaft 214 through the tension spring 254. When the unlocking rod 253 moves a preset distance along the length direction of the pull rod 23, the unlocking rod 253 is in the angle unlock position. As the pull rod 23 rotates, the unlocking rod 253 can fall into the fixing groove 2511 and any one of the normal grooves 2521, so that the pull rod 23 is in the first position, the second position, or the third position.

[0181] When it is necessary to adjust the pull rod 23 to the first included angle, the unlocking rod 253 extends along the length direction of the pull rod 23 so that the unlocking rod 253 disengages from the fixing groove 2511 and the normal groove 2521. The unlocking rod 253 is in the unlocked position. When the pull rod 23 is rotated, the pull rod 23 can rotate around the fixed axis 214 to the first included angle. When the unlocking rod 253 is released, under the action of the tension spring 254, the unlocking rod 253 moves in the opposite direction along the length direction of the pull rod 23 by a preset distance. Thus, the pull rod 23 can be restricted from continuing to rotate around the fixed axis 214, so as to stably keep the pull rod 23 in the first position.

[0182] When it is necessary to adjust the pull rod 23 to the second included angle, the unlocking rod 253 extends along the length direction of the pull rod 23 so that the unlocking rod 253 disengages from the fixing groove 2511 and the normal groove 2521. The unlocking rod 253 is in the unlocked position. When the pull rod 23 is rotated, the pull rod 23 can rotate around the fixed axis 214 to the second included angle. When the unlocking rod 253 is released, under the action of the tension spring 254, the unlocking rod 253 moves a preset distance in the opposite direction along the length direction of the pull rod 23. Thus, the pull rod 23 can be restricted from continuing to rotate around the fixed axis 214, so as to stably keep the pull rod 23 in the second position.

[0183] When it is necessary to adjust the pull rod 23 to the third included angle, the unlocking rod 253 extends along the length direction of the pull rod 23 so that the unlocking rod 253 disengages from the fixing groove 2511 and the normal groove 2521. The unlocking rod 253 is in the unlocked position. When the pull rod 23 is rotated, the pull rod 23 can rotate around the fixed axis 214 to the third included angle. When the unlocking rod 253 is released, under the action of the tension spring 254, the unlocking rod 253 moves a preset distance in the opposite direction along the length direction of the pull rod 23. Thus, the pull rod 23 can be restricted from continuing to rotate around the fixed axis 214, so as to stably keep the pull rod 23 in the third position.

[0184] The aforementioned fixing groove 2511 may include a first fixing groove 2511a and a second fixing groove 2511b, wherein the first fixing groove 2511a is used to rotatably engage with the fixing shaft 214, and the second fixing groove 2511b is used to engage with the unlocking rod 253. The number of the second fixing grooves 2511b is three, each corresponding to a normal groove 2521.

[0185] The aforementioned fastener 251 may further include a slide groove 2511c, which communicates with the second fixing groove 2511b to accommodate the unlocking rod 253 moving between the three second fixing grooves 2511b.

[0186] The aforementioned pull rod 23 is provided with a locking hole 23a so that the unlocking rod 253 can move in its length direction within the locking hole 23a.

[0187] See Figures 47 to 49 The aforementioned fastener 251 includes a first mounting portion 2512, a second mounting portion 2513, and a third mounting portion 2514. The first mounting portion 2512 is connected to the main support tube 211, the second mounting portion 2513 is connected to the wheel 22, and the third mounting portion 2514 is connected to the fixed shaft 214. The first mounting portion 2512, the second mounting portion 2513, and the third mounting portion 2514 can form a right-angle structure.

[0188] Furthermore, the fastener 251 also includes a fourth mounting portion 2515, which includes a mounting groove 2515a. The opening of the mounting groove 2515a of the fastener 251 of one of the two wheels 22 located at the same end faces upward, and the opening of the mounting groove 2515a of the fastener 251 of the other wheel 22 located at the same end faces downward, so that the fasteners 251 of the two adjacent trailers 2 are connected through the mounting groove 2515a.

[0189] See Figure 50The diagram shows two adjacent fasteners 251 in two trailers 2. The mounting groove 2515a of the fastener 251 on the left faces upward, while the mounting groove 2515a of the fastener 251 on the right faces downward. The fastener 251 on the right is lifted upward and moved closer to the fastener 251 on the left. Once the two mounting grooves 2515a are aligned, the fastener 251 is moved downward. Figure 50 As shown in (a). Continue until the two fasteners 251 are aligned, as shown in (a). Figure 50 As shown in (b).

[0190] See Figure 51 The diagram shows two trailers 2 secured together via mounting slots 2515a. (See also...) Figure 52 This is a schematic diagram showing three trailers 2 fixed together by mounting slots 2515a, which allow for the quick fixing and disassembly of at least two trailers 2.

[0191] Furthermore, the aforementioned trailer 2 may also include an auxiliary axle 215, which can be installed at the bottom of the fixing member 251 to increase the height of the frame 21. Off-road mountain bike wheels can be mounted via this auxiliary axle 215 to improve the overall stability of the wheel 22. Figure 53 As shown.

[0192] The above mainly describes the structure of trailer 2. This application may also specifically describe other structures of the transport system. Specifically, the transport system also includes a fixing component 3, which connects the boxes 11 of the box assembly 1 and / or the box assembly 1 and the trailer 2, such as... Figure 54 As shown in the diagram, the fixing component 3 is mainly installed between the boxes 11 of the box assembly 1, enabling cross-level fixing. For example, the box 11 located on the first layer can be connected to the box 11 located on the third or fourth layer through the fixing component 3.

[0193] Specifically, the fixing component 3 includes a webbing 31 and a buckle 32. The buckle 32 includes a male buckle 321 and a female buckle 322 configured to have a locked state and an unlocked state. One of the male buckle 321 and the female buckle 322 is provided on the housing 11 or the trailer 2, and the other of the male buckle 321 and the female buckle 322 is provided on the webbing 31. When the buckle 32 is in the locked state, the male buckle 321 and the female buckle 322 are engaged together. When the buckle 32 is in the unlocked state, the male buckle 321 and the female buckle 322 are disengaged.

[0194] See Figures 55 to 57The diagram shows that the male buckle 321 includes a male retainer 3211 and a male engaging part 3212, with the engaging part 3212 disposed on the male retainer 3211. The female buckle 322 includes a female retainer 3221, a locking part 3222, an elastic compensation part 3223, and an unlocking part 3224. The female retainer 3221 includes a locking groove 3221a and a mounting cavity 3221b, the shape of which matches the shape of the male engaging part 3212. The locking part 3222 is movably disposed within the mounting cavity 3221b of the female retainer 3221 and has a locked position and an unlocked position. When in the locked position, the locking part 3222 can engage with the male fastening part 3212 located in the engaging groove 3221a, and the latch 32 is in the locked state; when the locking part 3222 is in the unlocked position, the locking part 3222 can disengage from the male fastening part 3212 located in the engaging groove 3221a, and the latch 32 is in the unlocked state; the elastic compensation part 3223 is located between the female fastener 3221 and the locking part 3222, so that the locking part 3222 is in the locked position; the unlocking part 3224 is movably disposed in the mounting cavity 3221b, and can drive the locking part 3222 to switch from the locked position to the unlocked position. Through the cooperation of the male fastener 321 and the female fastener 322, the fixing component 3 and the corresponding fixing structure (box 11, trailer 2 or webbing 31) can be quickly disassembled.

[0195] The female card holder 3221 is used to form the engagement groove 3221a and the mounting cavity 3221b. It includes a first female card holder 32211 and a second female card holder 32212. The first female card holder 32211 mainly forms the engagement groove, and the first female card holder 32211 and the second female card holder 32212 are spliced ​​together to form the mounting cavity 3221b.

[0196] To further improve the fixing efficiency, the male buckle 321 also includes a first magnetic element 3213, and the female buckle 322 also includes a second magnetic element 3225. The second magnetic element 3225 and the first magnetic element 3213 are magnetically attracted to each other, and when the first magnetic element 3213 and the second magnetic element 3225 are in the locked position, the male buckle 321 and the female buckle 322 are in the locked position.

[0197] In addition, the first magnetic component 3213 and the second magnetic component 3225 also have the function of initial fixation. The fixing component 3 that is not fixed to the box 11 or the trailer 2 can be fixed by the magnetic force between the first magnetic component 3213 and the second magnetic component 3225 to prevent loss.

[0198] The function of the aforementioned locking part 3222 is to lock the male fastening part 3212. The locking part 3222 includes a first locking arm 32221 and a second locking arm 32222 arranged symmetrically. The middle part of the first locking arm 32221 and the middle part of the second locking arm 32222 are rotatably disposed in the mounting cavity 3221b. The side walls of the first locking arm 32221 and the second locking arm 32222 have a groove 3222a. When the locking part 3222 is in the locked position, the groove 3222a engages with the male fastening part 3212 located in the engagement groove 3221a. When the unlocking part 3224 moves to the preset position, it drives the groove 3222a to disengage from the male fastening part 3212.

[0199] The first clamping arm 32221 includes a first hinge hole 32221a, which is rotatably engaged with the positioning pin 322112a on the female clamping seat 3221, so as to realize the rotation of the first clamping arm 32221 relative to the female clamping seat 3221; the second clamping arm 32222 includes a second hinge hole 32222a, which is rotatably engaged with the positioning pin 322112a on the female clamping seat 3221, so as to realize the rotation of the second clamping arm 32222 relative to the female clamping seat 3221.

[0200] Furthermore, the aforementioned elastic compensation part 3223 can be a structure with elastic function, such as a spring.

[0201] The aforementioned unlocking part 3224 is slidably engaged with the first locking arm 32221 and the second locking arm 32222. This slidable engagement allows the first locking arm 32221 and the second locking arm 32222 to disengage from the male engagement part.

[0202] In order to drive the unlocking part 3224 back to its natural state, a third elastic member 3226 may be provided between the unlocking part 3224 and the mounting cavity 3221b. When the external force is removed, the third elastic member 3226 can drive the unlocking part 3224 back to its natural state.

[0203] The unlocking part 3224 has a first guide surface 3224a, and the first locking arm 32221 and the second locking arm 32222 have second guide surfaces 3222b. The first guide surface 3224a and the second guide surface 3222b form an acute angle with the movement direction of the unlocking part 3224. The first guide surface 3224a and the second guide surface 3222b are inclined surfaces. Therefore, when the unlocking part 3224 moves closer to the first locking arm 32221 and the second locking arm 32222, under the guidance of the first guide surface 3224a and the second guide surface 3222b, the unlocking part 3224 can move quickly towards the first locking arm 32221 and the second locking arm 32222, which can speed up the disengagement time of the first locking arm 32221 and the second locking arm 32222 with the male fastening part 3212.

[0204] See Figures 56 to 58 as well as Figure 60 The first locking arm 32221 and the second locking arm 32222, under the action of the elastic compensation part, engage with the male engaging part installed in the engaging groove 3221a, thereby locking the latch 32. See also Figure 59 The first locking arm 32221 and the second locking arm 32222 disengage from the male engagement part of the engagement groove 3221a under the action of the unlocking part 3224, thereby unlocking the latch 32.

[0205] It should be noted that the female buckle 322 and the male buckle 321 can be interchanged. In this embodiment, the female buckle 322 is mainly set on the webbing 31, and the male buckle 321 can be arranged on the box cover lock 111, the trailer 2 and / or the webbing 31 of the box assembly 1.
