Description

Technical Field

[0001] This invention relates to the field of unmanned driving technology, and in particular to an adjustable buckle, a shelf adjustment method, a cargo box, and an unmanned vehicle. Background Technology

[0002] Autonomous vehicles, or driverless cars, are of great significance in goods delivery and product transfer. When transporting goods, the goods are pre-placed in the cargo box, and the cargo box is layered with shelves and other structures to facilitate the placement of different types of goods.

[0003] In existing technologies, cargo boxes are generally equipped with adjustment mechanisms that connect to the shelves to adjust the height of the shelves within the cargo box. These adjustment mechanisms typically use a motor as the power source, coupled with a transmission structure such as a chain or lead screw, to achieve the adjustment function.

[0004] However, this adjustment mechanism is not only bulky and expensive, but also its load capacity is limited by the performance of the power components and transmission structure when goods are placed inside the shelf. Especially when applied to unmanned vehicles, the adjustment mechanism is easily damaged by the bumps during the ride, which can cause the shelf to become unstable. Summary of the Invention

[0005] The purpose of this invention is to provide an adjusting buckle, a shelf adjusting method, a cargo box, and an unmanned vehicle, which solves the problems of existing adjusting mechanisms for adjusting shelf positions being not only bulky and costly, but also prone to damage and causing shelf instability when applied to unmanned vehicles.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides an adjusting latch for connecting to the mounting strip of a shelf and detachably connecting to a cargo box to adjust the position of the shelf within the cargo box, comprising: a first latch, a connecting latch, and a second latch. The first latch is used to engage with the cargo box; the connecting latch is inserted into the first latch and forms an mounting notch for inserting the mounting strip. The second latch is used to engage with the cargo box and partially extends into the mounting notch, the second latch engaging with the side of the mounting notch to close the mounting notch.

[0008] Optionally, the first buckle includes: a first buckle block having a first hook for connecting with the cargo box; and a mounting block disposed on the side of the first buckle away from the first hook, wherein the upper side of the mounting block is recessed to form a mounting groove, the connecting buckle is inserted into the mounting groove and forms the mounting notch with the mounting groove, and the mounting notch has a mounting protrusion that abuts against the second buckle.

[0009] Optionally, the connecting buckle includes: a connecting block inserted into the mounting groove, the upper side of the connecting block being recessed to form a connecting groove for connecting with the mounting strip, the connecting groove and the space in the mounting groove not occupied by the connecting block forming the mounting notch; a first limiting plate disposed on one side of the connecting block and abutting against one side of the first buckle; and a second limiting plate disposed on the other side of the connecting block and abutting against the other side of the first buckle.

[0010] Optionally, the connecting buckle is made of an elastic material, the first limiting plate has a first insert block, the first buckle has a first slot for inserting the first insert block; and / or the second limiting plate has a second insert block, the end of the second insert block away from the second limiting plate extending into the second buckle.

[0011] Optionally, the second latch includes: a second latch block having a second hook that engages with the cargo box, the bending direction of the second hook being opposite to the bending direction of the first hook, and the lower side of the second latch block extending into the mounting notch and engaging with the side wall of the mounting notch to close the mounting notch.

[0012] Optionally, the lower side of the second buckle has an engagement portion that fits against the mounting strip.

[0013] Optionally, the first buckle is made of metal, and the second buckle is made of elastic material.

[0014] Secondly, the present invention provides a shelf adjustment method, which utilizes the adjusting buckle as described in any one of the first aspects to adjust the position of the shelf inside the cargo box, comprising: determining the installation position of the shelf inside the cargo box and engaging the first buckle at the installation position; after the first buckle is engaged and fixed, inserting the connecting buckle into the first buckle to form the installation notch; placing the installation strip of the shelf in the installation notch and engaging the second buckle sequentially with the cargo box and the installation notch to close the installation notch and fix the installation strip of the shelf, thereby fixing the shelf inside the cargo box.

[0015] Thirdly, the present invention provides a cargo box, comprising: a box body having a storage cavity inside the box body; and a shelf disposed within the storage cavity, wherein the shelf is provided with a plurality of adjusting buckles as described in any one of the first aspects above, the adjusting buckles being detachably connected to the box body to adjust the position of the shelf within the storage cavity.

[0016] Fourthly, the present invention provides an unmanned vehicle, comprising: a vehicle body; and a cargo box as described in any one of the second aspects above, disposed on the vehicle body.

[0017] The beneficial effects of this invention are:

[0018] Firstly, after determining the shelf's position based on the goods' dimensions, the first clip can be engaged inside the cargo box, and the connecting clips can be plugged in. Then, the shelf's mounting strip is placed in the mounting notch to determine the shelf's position relative to the cargo box. Once the shelf's position is determined, the second clip is used to engage with the cargo box and close the mounting notch, thus securing the shelf inside. When the shelf's position needs adjustment, the second clip can be manually removed to detach the shelf. This adjustment mechanism allows for both fixing and adjusting the shelf's position. The adjustment mechanism includes a first clip, a second clip, and a connecting clip, resulting in a simple structure, low manufacturing cost, and convenient installation and disassembly. Operators can quickly fix or remove the shelf from the cargo box using the adjustment mechanism. Furthermore, the three-part structure of the first clip, second clip, and connecting clip allows for the adaptation of different sized mounting strips by simply changing the size of the connecting slot in the connecting clip, reducing the adaptation cost of the adjustment mechanism. Simultaneously, the adjusting buckle is fixed to the cargo box, and the connection between the two is strong, so it can withstand a large load, allowing the rack to withstand a higher upper limit of load. Moreover, the fixed connection also makes the adjusting buckle stable and not easy to shake relative to the cargo box. The overall stability of the rack can be guaranteed. Therefore, when the cargo box is applied to unmanned vehicles and other autonomous driving fields, the goods inside the cargo box are more stable and less likely to shake, ensuring the safety of the goods.

[0019] Secondly, this method allows for the quick fixing and disassembly of shelves within the cargo box, enabling operators to adjust the shelf position according to the type and size of the goods. Furthermore, operators can monitor the shelf position in real time during the adjustment process, allowing them to determine whether the shelf position is appropriate and thus quickly complete the shelf adjustment.

[0020] Thirdly, before using the cargo box, appropriate buckles can be installed and adjusted according to the size, quantity, and weight of the goods to fix the shelf within the corresponding range of the cargo box. This allows for adjustment of the size of the layered space inside the cargo box to accommodate different goods and meet various user needs.

[0021] Fourthly, by adding the aforementioned cargo box to the unmanned vehicle, the unmanned vehicle can better realize functions such as cargo delivery or product transfer, so as to better meet the diverse needs of users. Attached Figure Description

[0035] This invention provides an adjustable latch, a shelf adjustment method, a cargo box, and an unmanned vehicle. It can adjust the position of the shelf inside the cargo box, and after adjustment, the adjustable latches secure the shelf to the cargo box, ensuring installation stability and effectively improving the load-bearing capacity. This not only increases the cargo box's capacity but also ensures the safety of goods stored inside. When this cargo box is applied to the unmanned vehicle, the vehicle can better and more safely and stably transport large quantities of goods, making unmanned or autonomous driving technology a promising application in cargo delivery and product transfer.

[0036] An adjusting buckle

[0037] Reference Figure 1 and Figure 2 As shown, the adjusting clip is used to connect with the mounting strip 41 of the shelf 4 and is detachably connected to the cargo box to adjust the position of the shelf 4 inside the cargo box. The adjusting clip includes a first clip 1, a connecting clip 2, and a second clip 3. The first clip 1 is engaged with the cargo box. The connecting clip 2 is inserted into the first clip 1 and forms a mounting notch 10 for connection with the mounting strip 41. The second clip 3 is engaged with the cargo box and partially extends into the mounting notch 10. The second clip 3 engages with the side of the mounting notch 10 to close the upper opening of the mounting notch 10.

[0038] Specifically, multiple vertically extending fixing frames 5 are installed inside the cargo box, and multiple spaced-apart locking holes 51 are formed on the fixing frames 5. The first latch 1 and the second latch 3 respectively engage with the corresponding locking holes 51 to fix the adjusting latch inside the cargo box. The fixing frames 5 can be installed according to the size of the shelf 4 to accommodate different goods. Alternatively, the locking holes 51 can be directly formed on the inner wall of the cargo box to further simplify the internal structure of the cargo box, save materials, and reduce costs.

[0039] The first buckle 1 is engaged in the opposite direction to the second buckle 3. For example, the first buckle 1 is engaged with the buckle hole 51 facing downwards, while the second buckle 3 is engaged with the corresponding buckle hole 51 facing upwards, so as to achieve the fixing of the buckle from two opposite directions.

[0040] The connecting buckle 2 is located between the first buckle 1 and the second buckle 3. The upper side of the connecting buckle 2 forms an installation notch 10 with the first buckle 1. The mounting strip 41 of the shelf 4 is placed in the installation notch 10. The lower side of the second buckle 3 can extend into the installation notch 10, and the lower side of the second buckle 3 abuts against the connecting buckle 2. The front and rear sides of the second buckle 3 abut against the first buckle 1 to close the installation notch 10 and fix the mounting strip 41 in the installation notch 10.

[0041] When adjusting the position of the shelf 4 inside the cargo box using the adjusting buckle, first determine the position of the shelf 4 according to the size of the goods. Then, first snap the first buckle 1 into the buckle hole 51, insert the connecting buckle 2, and then place the mounting strip 41 of the shelf 4 into the mounting notch 10. The operator can then observe whether the relative position of the shelf 4 inside the cargo box is appropriate. When it is determined that the position of the shelf 4 is appropriate, use the second buckle 3 to snap it into the buckle hole 51 and close the mounting notch 10 to fix the shelf 4 inside the cargo box.

[0042] When the position of shelf 4 needs to be adjusted, shelf 4 can be removed by manually disassembling the second clip 3. The position of shelf 4 can be adjusted using this adjusting clip. The adjusting clip includes a first clip 1, a connecting clip 2, and a second clip 3, etc. Its overall structure is simple, with low manufacturing cost, and the installation and disassembly processes are very convenient. Operators can quickly fix shelf 4 inside or remove it from the cargo box using the adjusting clip. Simultaneously, the adjusting clip is firmly engaged with the cargo box, and the connection strength is high, thus it can withstand a large load, allowing shelf 4 to withstand a higher upper limit of load. The engagement also ensures good stability of the adjusting clip, preventing it from wobbling relative to the cargo box. The overall stability of shelf 4 is guaranteed. Therefore, when this cargo box is used in autonomous driving fields such as unmanned vehicles, the goods inside the cargo box have good stability and are less prone to shaking, ensuring the safety of the goods.

[0043] Reference Figure 3As shown, in some embodiments of the present invention, the first latch 1 includes a first latching block 11 and a mounting block 12. The first latching block 11 has a first hook 13 that is connected to the cargo box. The mounting block 12 is disposed on the side of the first latching block 11 away from the first hook 13. The upper side of the mounting block 12 is recessed to form a mounting groove 120. The connecting latch 2 is inserted into the mounting groove 120 and forms a mounting notch 10 with the mounting groove 120. The mounting notch 10 has a mounting protrusion 121 that abuts against the second latch 3.

[0044] Specifically, the first locking block 11 is in the shape of a vertical plate and extends vertically. A first locking hook 13 is disposed on one side of the first locking block 11. The first locking hook 13 is plate-shaped, and its side away from the first locking block 11 is bent downwards to form a gap with the first locking block 11 that connects with the side wall of the locking hole 51. Multiple first locking hooks 13 may be distributed at intervals along the extending direction of the first locking block 11; this invention does not impose a specific limitation. In one embodiment, two first locking hooks 13 are provided, located on the upper and lower sides of the first locking block 11, respectively.

[0045] The mounting block 12 is integrally injection molded with the first locking block 11 and is located on the side of the first locking block 11 away from the first locking hook 13. The top wall of the mounting block 12 is recessed to form a U-shaped mounting groove 120 with the first locking block 11. The connecting buckle 2 is partially inserted into the mounting groove 120. The connecting buckle 2 has a groove and other structures. The groove and the space in the mounting groove 120 not occupied by the connecting buckle 2 form a mounting notch 10.

[0046] The mounting protrusion 121 is located at the opening of the mounting groove 120 and is positioned above the connecting buckle 2. The lower side of the second buckle 3 can extend into the mounting notch 10, with one side abutting against the side of the first latch block 11 and the other side abutting against the mounting protrusion 121, thereby sealing the upper opening of the mounting notch 10. The mounting protrusion 121 can be strip-shaped, spaced-apart hemispherical, or block-shaped with beveled surfaces. In one embodiment, the mounting protrusion 121 is strip-shaped and extends along the left-right direction of the mounting block 12.

[0047] When installing the first buckle 1, the first hook 13 is hooked from top to bottom into the corresponding buckle hole 51, which can fix the first buckle block 11 on the fixing frame 5. Multiple first hooks 13 can ensure that the first buckle block 11 is subjected to uniform force, and the plate-shaped first hooks 13 can have a large contact area with the fixing frame 5, which can ensure that the first buckle block 11 will not shake.

[0048] After placing the first clip 11, insert the connecting clip 2 into the mounting groove 120 to form the mounting notch 10. Then, place the mounting strip 41 into the mounting notch 10 and use the second clip 3 to close the upper opening of the mounting notch 10. This will quickly complete the installation and fixing of the adjusting clip.

[0049] Reference Figure 3 As shown, in some embodiments of the present invention, the gap between the first hook 13 and the first locking block 11 decreases from the first side to the second side. The first side is the side where the first hook 13 is inserted into the locking hole 51, and the second side is opposite to the first side. Specifically, the thickness of the first hook 13 increases from the first side to the second side, so that the gap width gradually decreases. In this way, when the first hook 13 is inserted into the locking hole 51, as the gap decreases, the first hook 13 can fit tightly against the fixing frame 5, thereby avoiding the situation where there is a gap between the first hook 13 and the fixing frame 5, which would cause the first buckle 1 to wobble.

[0050] It should be understood that the reduction in gap width can also be achieved by bonding elastic pads or other structures within the gap, or by providing beveled pads or other structures at the positions corresponding to the locking holes 51 on the fixing frame 5, which can also fill the gap between the first locking hook 13 and the fixing frame 5 in the reverse direction. The specific filling of the gap between the first locking hook 13 and the fixing frame 5 can be designed according to the actual application scenario, and this invention does not impose any limitations.

[0051] Reference Figure 3 As shown, in some embodiments of the present invention, the connecting buckle 2 includes a connecting block 20, a first limiting plate 21, and a second limiting plate 22. The connecting block 20 is inserted into the mounting groove 120, and the upper side of the connecting block 20 is recessed to form a connecting groove 201 through which the mounting strip 41 passes. The internal space of the connecting groove 201 and the space of the mounting groove 120 not occupied by the connecting block 20 together form a mounting notch 10. The first limiting plate 21 is disposed on one side of the connecting block 20 and abuts against one side of the first locking block 11. The second limiting plate 22 is disposed on the other opposite side of the connecting block 20 and abuts against the other side of the first locking block 11, so that the upper end of the first buckle 1 is clamped between the first limiting plate 21 and the second limiting plate 22.

[0052] Specifically, the connecting block 20 is U-shaped to form the connecting groove 201, and its outer side wall can fit against the groove wall of the mounting groove 120. The upper end height of the connecting block 20 is less than the upper end height of the mounting groove 120, and the upper end face of the connecting block 20 abuts against the lower side of the second buckle 3 to limit the depth of the second buckle 3 inserted into the mounting notch 10.

[0053] The connecting block 20, the first limiting plate 21, and the second limiting plate 22 are integrally formed. The first limiting plate 21 is located on the left side of the connecting block 20 and extends downward. The side of the first limiting plate 21 abuts against the side of the first locking block 11 and the mounting block 12. The second limiting plate 22 is located on the right side of the connecting block 20 and extends upward. Its height is greater than the height of the first latch 1. The side of the second limiting plate 22 abuts against the other side of the first locking block 11 and the mounting block 12. The second limiting plate 22 corresponds to the second latch 3 to limit the movement range of the second latch 3.

[0054] After the first clip 1 is fixed to the fixing bracket 5, when placing the connecting clip 2, the connecting block 20 is placed into the mounting groove 120, ensuring that the connecting block 20 is tightly against the side wall of the mounting groove 120, and that the first limiting plate 21 and the second limiting plate 22 abut against the two sides of the first clip 1 respectively, thus completing the fixing of the connecting clip 2. When the second clip 3 is inserted, the lower side of the second clip 3 abuts against the upper side of the connecting block 20, thus completing the closure of the mounting notch 10.

[0055] Reference Figure 3 As shown, in some embodiments of the present invention, the connecting buckle 2 is made of an elastic material, the first limiting plate 21 has a first insert 211, and the first buckle 1 has a first slot 14 for inserting the first insert 211. And / or the second limiting plate 22 has a second insert 221, the end of the second insert 221 away from the second limiting plate 22 extending into the second buckle 3.

[0056] Specifically, the connecting clip 2 can be made of elastic plastic, possessing both a certain degree of hardness and elasticity. When the mounting strip 41 is installed in the adjusting clip, the elasticity of the connecting clip 2 allows the mounting strip 41 to fit snugly within the mounting notch 10, reducing relative movement between the adjusting clip and the mounting strip 41 and facilitating easy assembly and disassembly by the operator. It should be understood that the connecting clip 2 can also be made of materials that meet the requirements of both hardness and elasticity; this invention does not impose a specific limitation.

[0057] The first limiting plate 21 has a protruding side forming a first insertion block 211, which is located below the mounting groove 120. The first latch 1 also includes a connecting plate 141. The connecting plate 141 is disposed between the first latch 11 and the mounting block 12, and is located below the mounting block 12. A first slot 14 for the first insertion block 211 to be inserted is formed between the first latch 11, the mounting block 12, and the connecting plate 141. The shape of the first insertion block 211 can be cylindrical or polygonal, and the shape and arrangement of the connecting plate 141 can be designed according to the shape of the first insertion block 211. In one embodiment, the first insertion block 211 is triangular prism-shaped, then the connecting plate 141 is inclined, so that the first slot 14 is also triangular prism-shaped.

[0058] The second insert 221 is located on the side of the second limiting plate 22 near the second latch 3 and extends along the thickness direction of the second limiting plate 22. Its end away from the second limiting plate 22 extends into the second latch 3, where a slot is formed for the second insert 221 to be inserted. The shape of the second insert 221 can be cylindrical or polygonal; this invention does not impose a specific limitation. In one embodiment, the second insert 221 is a long strip extending vertically.

[0059] With the first insert 211 and the second insert 221 in place, when installing the connecting buckle 2, the connecting block 20 is inserted from left to right into the mounting groove 120 of the first buckle 1. The second limiting plate 22 is squeezed and deformed so that it can pass smoothly through the mounting groove 120. When the second limiting plate 22 passes through the mounting groove 120, the first insert 211 is just fully inserted into the first slot 14, thus completing the connection between the connecting buckle 2 and the first buckle 1.

[0060] After placing the installation strip 41 into the connecting groove 201, the second buckle 3 is engaged with the corresponding buckle hole 51 by rotating the installation. At the same time, the second insert block 221 is inserted into the corresponding slot of the second buckle 3, so that the connecting buckle 2 stably connects the first buckle 1 and the second buckle 3 together, thus completing the buckle engagement installation.

[0061] Reference Figure 3 As shown, in some embodiments of the present invention, the second latch 3 includes a second latch block 30. The second latch block 30 has a second hook 31 that is connected to the cargo box. The bending direction of the second hook 31 is opposite to the bending direction of the first hook 13. The lower side of the second latch block 30 extends into the mounting notch 10 and engages with the side wall of the mounting notch 10 to close the mounting notch 10.

[0062] Specifically, the second locking block 30 is cubic with a hollow interior to save manufacturing costs. Reinforcing ribs 32 can be provided inside the second latch 3 to improve the overall strength of the second locking block 30. The second hook 31 is located on the front sidewall of the second locking block 30 and is positioned opposite to the first hook 13, i.e., the second hook 31 is bent upwards. The lower side of the second locking block 30 extends into the mounting notch 10. The front side of the second locking block 30 abuts against the sidewall of the mounting groove 120, and the rear side abuts against the mounting protrusion 121 to form a locking connection. The lower side of the second locking block 30 abuts against the top wall of the connecting block 20. The second insert 221 can be inserted into the interior of the second locking block 30, and its shape can be set according to the internal shape of the second insert 221.

[0063] When installing the second clip 3, the second hook 31 should face upwards, and the second clip block 30 should be tilted downwards to align with the corresponding clip hole 51. The second hook 31 should be inserted into the corresponding clip hole 51 by rotating clockwise, while the lower side of the second clip block 30 gradually enters the installation notch 10. When the second clip block 30 is engaged in the installation notch 10, the second hook 31 is engaged with the clip hole 51, and the second insert 221 is simultaneously inserted into the second clip block 30, successfully completing the installation of the second clip 3. For disassembly, simply rotate the second clip block 30 counterclockwise to separate the second hook 31 from the clip hole 51, quickly completing the disassembly.

[0064] Reference Figure 3 As shown, in some embodiments of the present invention, the lower side of the second buckle 3 has an engagement portion 301 that engages with the mounting strip 41.

[0065] Specifically, the front and rear side walls of the U-shaped connecting block 20 have different heights, with the front side being higher than the rear side. Correspondingly, the rear side of the lower side wall of the second locking block 30 is lower than the front side, thereby making the lower side wall of the second locking block 30 bend to form the aforementioned fitting part 301. The bend shape of the fitting part 301 forms a line contact with the mounting strip 41 at a larger or more contact position.

[0066] By setting the fitting part 301, the second buckle 3 can better contact the installation strip 41 during installation, so that the second buckle 3 can fix the installation strip 41 while closing the installation notch 10, reducing the possibility of the installation strip 41 shaking, thereby further improving the installation stability of the shelf 4.

[0067] Reference Figure 3 As shown, in some embodiments of the present invention, the first buckle 1 is made of metal, and the second buckle 3 is made of elastic material. Specifically, the first buckle 1 is made of alloy material, iron, or other metal material to ensure good overall load-bearing capacity. The second buckle 3 can be made of elastic plastic, allowing it to deform during rotational installation or disassembly for easier assembly and disassembly. Furthermore, the second buckle 3, made of elastic material, has a fitting portion 301 on its lower sidewall that deforms with the shape of the mounting strip 41, facilitating better contact between the fitting portion 301 and the mounting strip 41.

[0068] In some embodiments of the present invention, in order to ensure that the second buckle 3 is installed more conveniently, the rear side of the second buckle 30 is recessed into an inclined V-shape. Because it is elastic, the V-shape allows the second buckle 30 to have a larger deformation margin when it is snapped in, so that it can be snapped in smoothly with the connecting buckle 2 and the first buckle 1.

[0069] A shelf adjustment method

[0070] Reference Figure 4 As shown, this shelf adjustment method utilizes the adjustment latches as described in any of the above embodiments to adjust the position of the shelf 4 inside the cargo box, including:

[0071] Step S1: Determine the installation position of the shelf 4 inside the cargo box and snap the first buckle 1 into place at the installation position.

[0072] The installation location refers to the fixed position of the shelf 4 within the cargo box. Depending on the type and size of the goods, shelves 4 can be placed within the cargo box to create layered spaces. Different installation locations of the shelf 4 result in different layered spaces. Layered spaces directly affect the quantity and orientation of the goods. Therefore, when determining the type, size, and quantity of goods, the required size of the layered space for storing those goods can be determined, thus determining the installation location of the shelf 4 within the cargo box. It should be understood that layered spaces can include multiple layers; for example, installing a single shelf can create two layers (top and bottom) or two layers (left and right). The specific number and size of the layered spaces can be determined based on the actual goods, and this application does not impose any limitations.

[0073] Step S2: After the first buckle 1 is engaged and fixed, insert the connecting buckle 2 into the first buckle 1 to form the installation notch 10.

[0074] After determining the installation location, the first clip 1 is directly engaged into the clip hole 51 of the fixing frame 5 to mark the installation location, making it easy for operators to identify the shelf's position and thus allowing for a preliminary estimate of the tiered space size. Once the first clip 1 is engaged and secured, the connecting clip 2 is installed. After the connecting clip 2 is inserted, an installation notch 10 with an opening is formed, allowing the mounting strip 41 of the shelf 4 to be placed within the notch 10. At this point, the size of the tiered space can be determined by placing the shelf 4. If the tiered space size is unsuitable, the positions of the first clip 1 and the connecting clip 2 are adjusted accordingly to change the installation location.

[0075] Step S3: Place the mounting strip 41 of the shelf 4 into the mounting notch 10 and engage the second buckle 3 with the cargo box and the mounting notch 10 in sequence to close the mounting notch 10 and fix the mounting strip of the shelf 4, so that the shelf 4 is fixed inside the cargo box.

[0076] Once it is determined that the installation position of the shelf 4 is suitable and the resulting layered space can accommodate the loading of all goods, the second clip 3 can be installed in the corresponding installation notch 10. The second clip 3 first engages with the locking hole 51 on the fixing frame 5 at the installation position, and then gradually inserts into the opening of the installation notch 10 to close the installation notch 10. By closing the installation notch 10, the mounting strip 41 of the shelf 4 is fixed within the installation notch 10, thus completing the installation and fixing of the shelf 4. When it is necessary to disassemble the shelf 4, first separate the second clip 3 from the installation notch 10, and then separate the second clip 3 from the locking hole 51, so that the shelf 4 can be removed for adjustment.

[0077] Through the above steps S1, S2 and S3, the shelf 4 can be quickly fixed and disassembled in the cargo box, so that the operator can adjust the position of the shelf 4 according to the type and size of the goods. Moreover, the operator can know the position of the shelf 4 in real time during the adjustment process, so as to judge whether the position of the shelf 4 is appropriate and thus quickly complete the adjustment of the shelf 4.

[0078] A cargo box

[0079] Reference Figure 5 and Figure 6 As shown, the cargo box includes a box body 6, a shelf 4, and adjusting latches as described in any of the above embodiments. The box body 6 has a storage cavity. The shelf 4 is disposed in the storage cavity and is provided with multiple adjusting latches, which are detachably connected to the box body 6 to adjust the position of the shelf 4 within the storage cavity.

[0080] Specifically, multiple fixing brackets 5 are placed inside the cargo box, distributed around the circumference of the shelf 4. Each fixing bracket 5 has multiple locking holes 51 spaced vertically for engaging with corresponding adjusting buckles. The shelf 4 can be disc-shaped or square-shaped, with the adjusting buckles spaced along its circumference to ensure even force distribution. In one embodiment, the shelf 4 is square-shaped, with an adjusting buckle and a fixing bracket 5 at each of its four corners.

[0081] Before using the cargo box, the appropriate clips 51 can be selected to install adjustment buckles according to the size, quantity and weight of the goods, so as to fix the shelf 4 in the corresponding range inside the cargo box. This allows the size of the layered space inside the cargo box to be adjusted as needed to accommodate different goods and meet various user needs.

[0082] Meanwhile, the adjustable buckles are fixed to the cargo box via snap-fit ​​connections, resulting in a high connection strength and good load-bearing capacity for shelf 4. This allows the cargo box to be used for a wider variety of goods. The multiple adjustable buckles also ensure the stability of shelf 4, guaranteeing the safety of goods inside the cargo box.

[0083] Reference Figure 7 As shown, in some embodiments of the present invention, the shelf 4 has a fence 42 extending circumferentially along the shelf 4.

[0084] Specifically, the shelf 4 is formed by multiple metal rods arranged in a crisscross pattern. At the edges of the shelf 4, metal rods can be used to form a fence 42 along the vertical direction. The fences 42 on all four sides of the shelf 4 are fixed to the shelf 4. Alternatively, only the front fence 42 can be detachably connected to the shelf 4 by plugging or snapping, so as to facilitate the storage and retrieval of goods.

[0085] Reference Figure 6 As shown, in some embodiments of the present invention, the box body 6 may include multiple unit cavities, each of which is provided with multiple shelves 4 to improve the carrying capacity of the box. Each unit cavity is provided with a corresponding door 60, and an electronic lock 601 may also be provided inside the box to automatically lock the door 60. The door 60 can be opened by sliding left and right or by flipping up and down, depending on the installation space of the box body 6, and the present invention does not limit it. In one embodiment, the box body 6 is provided with three unit cavities, and each unit cavity is provided with two shelves 4.

[0086] In some embodiments of the present invention, the top wall of the box 6 may also be provided with a ventilation opening 62, which can be connected to a corresponding temperature control mechanism (not shown in the figure) to both expel the air inside the box 6 in a timely manner and replenish the box 6 with hot or cold air, thereby adjusting the temperature inside the box 6 in real time so that the goods inside the box 6 can be stored at a suitable temperature.

[0087] In some embodiments of the present invention, a maintenance cabinet 61 may also be provided on the back of the container 6. The maintenance cabinet 61 is equipped with the electrical components required by the container 6. When maintenance is required, the operating status of the container can be understood directly through the maintenance cabinet 61 in a timely manner, so as to facilitate subsequent maintenance work.
