For the packaging boxes of this type of product, the current loaded power battery pack is 2307mm long and 1362mm wide, and the size of the international sea and land transport container is 11.7 meters X2.3 meters. Due to the limitation of the width of the container and the specifications of the battery pack, it can only be placed horizontally in the container in the width direction after packaging. The original packaging boxes used are wooden packaging boxes with iron nails, and the shape is a regular square box and a square pallet. In the width direction, only 4 rows and 3 layers of 12 can be placed in the container, and the loading rate is low, resulting in high transportation costs.

[0004] The prior art also includes a pentagonal wooden box assembly disclosed in publication number CN215098862U. The wooden box assembly disclosed in the prior art is designed as a pentagon, one side of which is a hypotenuse and the other are right-angled sides. The wooden box assembly is not conducive to stacking. Utility Model Content

[0022] The packaging box described in the utility model can be used to load power batteries (lithium batteries). Currently, the materials used for packaging power batteries include plastic or wood. Considering that some countries or regions limit power battery packaging boxes to one-time use, which will cause environmental pollution, etc., wood is still the main material at present. Therefore, the packaging box described in the utility model includes wooden materials and other materials.

[0023] Combination Figure 1-Figure 5 As shown, the packaging box provided by the utility model is composed of an upper cover plate 101, a side plate 102 and a bottom plate 103 to form a box body 1. The side edges, the bottom and the top can be spliced ​​and fixed by using iron angles 7 and screws 8. For the box body 1, in order to realize the splicing of two or more boxes 1, a right-angle (L-shaped) splicing part 2 is provided at one corner of the box body 1. The size of the notch can be designed according to actual needs. Figure 1 For example, the notch can be used as a rotation point, and rotating 180° can achieve the matching of the splicing part 2 to complete the splicing.

[0024] In order to improve the toughness and rigidity of the plate, the upper cover plate 101, the side plate 102 and the bottom plate 103 may be provided with reinforcement members 4, and the reinforcement members 4 function like reinforcing ribs, including being provided by laminating the strip plates.

[0025] In order to improve the carrying convenience, a handle 3 is provided on the box body 1.

[0026] Furthermore, in the box body 1 provided by the utility model, for the upper cover plate 101, its upper surface is provided with a protrusion 6, and the protrusion 6 is located above the side plate 102 and is in a nearby position. When the boxes 1 are stacked, the protrusion 6 can be used to support the upper box body 1, and the balance of gravity is achieved through the protrusion 6 as a force point. It is arranged near the top of the side plate 102, and the gravity can be borne by the vertically arranged side plate. The side plate is arranged vertically, and the pressure it bears is naturally higher than that of a flat plate placed flat. Due to the disordered placement, the middle part of the upper cover plate 101 in the prior art will not collapse, or a certain deformation will occur, which will cause squeezing of the internal space of the box body 1. In severe cases, the internal power battery will be damaged, or rupture, leakage, or easy to catch fire will occur. In order to make the upper cover 101 fall into the corresponding position of the box 1 quickly and accurately, a limit block 5 is set below the upper cover 101. The limit block 5 is inside the box 1 and fits the side plate 102, so that the upper cover 101 will not shake randomly before being fixed and sealed. For the bottom plate 103, a positioning block 9 is set to stabilize the power battery and avoid shaking in the box, which may cause danger. Figure 5 The positioning block 9 shown can also be provided with a right-angle notch to fix the rectangular battery pack, that is, a large packaging box can be used to package one or more small power battery packs. Below the bottom 103, in order to better weigh, combined with the setting and function of the protrusion 6 on the upper cover 101, the tray can achieve better pressure resistance and avoid moisture. More importantly, it can be carried after several layers are stacked.

[0027] The packaging box realized by technical personnel in this field according to the above technical solution belongs to the scope of protection requested by the present utility model, and the present utility model does not limit its size and the size specifications of its components. For example, the above-mentioned limit blocks 5, positioning blocks 9, etc. can be set to long strips, etc. according to conventional technical means.
