That is, a plurality of first reinforcing bars 40 are used to enhance the structural strength of the bottom tray 10, and a plurality of second reinforcing bars 50 are used to enhance the structural strength of the cover plate 30. In this way, the load-bearing capacity of the bottom tray 10 can be improved through a plurality of first reinforcing bars 40, and the situation that the bottom tray 10 is deformed after placing the new energy battery cover on the bottom tray 10 can be prevented. A plurality of second reinforcing bars 50 are used to improve the load-bearing capacity of the cover plate 30, so that the situation that the cover plate 30 is deformed after stacking a plurality of enclosure boxes can be prevented.

[0040] In some embodiments, an avoidance groove 11 is provided on the upper surface of the bottom tray 10, and the avoidance groove 11 is used for the protruding part of the new energy battery cover to extend into.

[0041] Specifically, the protruding part of the new energy battery cover specifically refers to the protruding part of the power connection port of the new energy battery power supply. When the new energy battery cover is placed on the bottom tray 10, the protruding part will be inserted into the avoidance groove 11, that is, the avoidance groove 11 is used to receive the protruding part of the new energy battery cover, so that the new energy battery cover is placed parallel to the bottom tray 10. There is no need to fill pads between other positions of the new energy battery cover and the bottom tray 10 for the parallel placement of the new energy battery cover. Such a setting is beneficial to reducing the occupied space. Of course, in other embodiments, the avoidance groove 11 is not provided on the upper surface of the bottom tray 10.

[0042] In some embodiments, a first limiting portion is provided on the upper surface of the cover plate 30, and a second limiting portion is provided on the lower surface of the bottom tray 10. The cover plate 30 and the bottom tray 10 of another enclosure box are mutually limited and matched through the first limiting portion and the second limiting portion. Specifically, when the bottom tray 10 of another enclosure box is placed above the cover plate 30, the first limiting portion and the second limiting portion are mutually limited and matched, so that the bottom tray 10 can be stably placed on the cover plate 30, which is beneficial to improving the placement stability of another enclosure box.

[0043] Furthermore, the first limiting portion forms a limiting clamping protrusion 31 , and the second limiting portion forms a limiting clamping groove 16 . The cover plate 30 and the bottom bracket 10 of another enclosure box are mutually limited and matched through the limiting clamping protrusion 31 and the limiting clamping groove 16 .

[0044] Specifically, when the base 10 of another enclosure box is placed on the cover plate 30, the limit protrusion 31 is rubbed in the limit slot 16, and the limit protrusion 31 and the limit slot 16 are limited to each other. The limit protrusion 31 and the limit slot 16 are limited by the structure, which is simple in structure and easy to produce.

[0045] Furthermore, the lower surface of the base 10 is provided with a support leg 15, and the limit slot 16 is recessed on the side of the support leg 15 away from the base 10. In this way, there is no need to provide an additional protruding structure on the base 10, and the setting of the limit slot 16 on the side of the support leg 15 away from the base 10 will not affect the use of the support leg 15. In other embodiments, the lower surface of the base 10 is provided with a limit column, the limit column extends in a direction away from the base 10, and the limit slot 16 is provided on the side of the limit column away from the base 10.

[0046] In some embodiments, the upper surface of the cover plate 30 is provided with multiple first limiting portions, and the lower surface of the base 10 is provided with multiple second limiting portions. The cover plate 30 and the base 10 of another enclosure box are mutually limited and matched through the multiple first limiting portions and the multiple second limiting portions in a one-to-one correspondence.

[0047] Specifically, the number of the first limiting parts is at least two, and similarly, the number of the second limiting parts corresponds to the number of the first limiting parts, that is, a plurality of first limiting parts and a plurality of second limiting parts are plugged and limited one by one, which is conducive to further improving the placement stability of the enclosure box. Of course, in other embodiments, the upper surface of the cover plate 30 is provided with a first limiting part, and similarly, the lower surface of the base 10 is also provided with only one second limiting part.

[0048] In some embodiments, the upper surface of the cover plate 30 has a plurality of reinforcing portions 32 , which are spaced apart from each other, and each reinforcing portion 32 is formed with a plurality of grooves, which are spaced apart from each other, and each groove forms a reinforcing rib on the bulge of the cover plate 30 .

[0049] Specifically, the reinforcing ribs protruding from the lower surface of the cover body can improve the structural strength of the cover plate 30. When two enclosure boxes are stacked, the support legs 15 of the bottom bracket 10 of another enclosure box abut against the multiple reinforcing parts 32, which is conducive to further improving the load-bearing capacity of the cover plate 30. Exemplarily, the multiple reinforcing parts 32 can be but not limited to two, three, four, etc. Of course, in other embodiments, only one reinforcing part 32 is provided on the cover plate 30.

[0050] In some embodiments, a plurality of first positioning notches are provided on the outer peripheral edge of the cover plate 30, and the plurality of first positioning notches are circumferentially spaced apart along the cover plate 30. A plurality of second positioning notches are provided on the outer peripheral edge of the bottom tray 10, and the plurality of second positioning notches are circumferentially spaced apart along the bottom tray 10. The plurality of first positioning notches and the plurality of second positioning notches correspond one by one to form a plurality of bundling positions for bundling with a strap.

[0051] Specifically, there are at least two first positioning notches, and the two first positioning notches are respectively arranged on opposite sides of the cover plate 30. Similarly, there are at least two second positioning notches, and the two second positioning notches are respectively arranged on opposite sides of the bottom tray 10, and the two first positioning notches and the two second positioning notches are correspondingly arranged.

[0052] When bundling the pallet box, it can be bundled through the bundling positions formed between the first positioning notches and the second positioning notches. During the bundling process, the first positioning notches and the second positioning notches can limit the strap, prevent deviation, and reduce the bundling difficulty of the staff for the pallet box. Of course, in other embodiments, the outer peripheral edge of the cover plate 30 is not provided with the first positioning notches.

[0053] In some embodiments, the annular pallet includes at least four interconnected baffles 21, and any two adjacent baffles 21 are connected by a flexible part, so that the annular pallet has a folded state in which at least two baffles 21 are stacked together.

[0054] Specifically, the four baffles 21 can move relative to each other and can move towards the adjacent baffle 21 to approach or move away. When the annular pallet 20 is idle, it can be folded so that the frame-shaped annular pallet 20 is folded into a state in which at least two baffles 21 are stacked together, which can reduce the occupied space of the annular baffle and thus facilitate storage. When the annular pallet 20 needs to be used, it only needs to be restored to the frame shape. Herein, at least four baffles 21 means that at least four baffles 21 are provided, rather than only four baffles 21 can be provided. In other embodiments, an even number of baffles 21 such as six, eight, ten, etc. can also be provided.

[0055] In some embodiments, the first mounting portion forms a first annular groove 14, and one end of the annular pallet 20 is inserted and matched with the first annular groove 14.

[0056] Specifically, when the annular shroud 20 needs to be installed on the base 10, the annular shroud 20 can be directly inserted into the first annular groove 14. When the annular shroud 20 needs to be disassembled from the base 10, only by disengaging the annular shroud 20 from the plug-in fit with the first annular groove 14 can the annular shroud 20 be disassembled from the base 10, so as to facilitate separate storage. The entire installation and disassembly operations are relatively simple, improving the user experience. Of course, in other embodiments, the first mounting portion forms a first annular protrusion, and one end of the annular shroud 20 is provided with a slot, and the annular shroud 20 is in plug-in fit with the first annular protrusion.

[0057] In some embodiments, the upper surface of the base 10 is provided with a plurality of first reinforcing blocks and a plurality of first reinforcing ribs 17. The plurality of first reinforcing blocks 13 and the plurality of first reinforcing ribs 17 are both located inside the first mounting portion. The plurality of first reinforcing blocks 13 are arranged at intervals, and adjacent two first reinforcing blocks 13 are connected by a first reinforcing rib 17.

[0058] Specifically, the plurality of reinforcing blocks and the plurality of reinforcing ribs protrude from the upper surface of the base 10, and the plurality of reinforcing blocks are connected together by the plurality of first reinforcing ribs 17. It can be understood that the plurality of first reinforcing blocks 13 and the plurality of first reinforcing ribs 17 can effectively improve the structural strength of the base 10, which is beneficial to further enhancing the load-bearing capacity of the base 10. Among them, the plurality of first reinforcing blocks 13 can be two, three, four or more. When the number of the first reinforcing blocks 13 is two, only one first reinforcing rib 17 can be provided, and one first reinforcing rib 17 connects the two first reinforcing blocks 13. Of course, two, three, four or more can also be provided. Of course, in other embodiments, only one first reinforcing block 13 can also be provided on the upper surface of the base 10.

[0059] In some embodiments, the first mounting portion includes a first annular baffle. The first annular baffle 12 is in the form of a continuous ring extending along the circumference of the base 10. The plurality of first reinforcing blocks 13 and the plurality of first reinforcing ribs 17 are located inside the first annular baffle 12, and the plurality of first reinforcing blocks 13 and the inner side wall of the first annular baffle 12 are spaced apart to form a first annular groove 14.

[0060] In some embodiments, the second mounting portion forms a second annular groove, and the second annular groove is in plug-in fit with the end of the annular shroud 20 away from the base 10. Specifically, the plug-in fit manner between the second annular groove and the annular shroud 20 is the same as the plug-in fit manner between the first annular groove 14 and the annular shroud 20. For reference, the description of the first annular groove 14 above can be referred to, and it will not be elaborated one by one in this embodiment.

[0061] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
