[0031] Reference Figure 1A packaging box for lithium batteries, comprising: a carton 900, a pressure-resistant protective layer 100, a buffer protective layer 300 and an electrostatic treatment layer 200, the carton 900 is provided with a loading bin 500; the pressure-resistant protective layer 100 is arranged in the carton 900, the pressure-resistant protective layer 100 and the carton 900 are fixed to each other, and the pressure-resistant protective layer 100 surrounds the loading bin 500; the buffer protective layer 300 is arranged in the carton 900, the buffer protective layer 300 surrounds the loading bin 500, the pressure-resistant protective layer 100 surrounds the buffer protective layer 300, and the buffer protective layer 300 is movably filled with buffer particles 350; the electrostatic treatment layer 200 is arranged between the pressure-resistant protective layer 100 and the buffer protective layer 300, the carton 900 is provided with a grounding terminal 800, the electrostatic treatment layer 200 is electrically connected to the grounding terminal 800, and the electrostatic treatment layer 200 can guide the static electricity in the carton 900 to flow to the grounding terminal 800. After multiple lithium batteries are loaded into the loading bin 500, they can be transported and handled together through the carton 900, and the lithium batteries can be protected by the pressure-resistant protective layer 100, the buffer protective layer 300 and the electrostatic treatment layer 200. In the process of transporting and handling the carton 900, the pressure-resistant protective layer 100 can directly resist the impact on the carton 900 on the outside of the buffer protective layer 300 and the electrostatic treatment layer 200, thereby slowing down or avoiding the deformation and damage of the carton 900, and further providing protection for the electrostatic treatment layer 200, the buffer protective layer 300 and the lithium batteries inside. The electrostatic treatment layer 200 can guide the static electricity generated by the movement in the carton 900 to the ground terminal 800 in a timely manner, so that the static electricity can be smoothly discharged to the outside of the carton 900 through the ground terminal 800. The buffer protection layer 300 can attenuate the impact force borne by the carton 900 through the activity of the buffer particles 350, thereby reducing the impact on the lithium battery, and effectively avoiding the problem of damage to the lithium battery under the action of the impact force. As a result, the lithium battery loaded in the carton 900 can obtain comprehensive anti-collision, anti-impact, and anti-static protection effects, thereby ensuring that the carton 900 can load the lithium battery more safely and reliably, and thus the transportation and handling of the lithium battery can be carried out smoothly and stably.

[0032] Specifically, there are multiple compression protection layers 100, all of which are paperboards, and the multiple compression protection layers 100 are folded and assembled to form a carton 900. Furthermore, the compression protection layer 100 is a high-weight kraft paper, and the surface is coated with a nano-silicon dioxide modified coating, so as to improve the wear resistance and waterproofness of the compression protection layer 100.

[0033] In certain embodiments, reference Figure 2There is a gap 600 between the compression protection layer 100 and the buffer protection layer 300, and the electrostatic treatment layer 200 is arranged in the gap 600; a shaping frame 700 is arranged in the gap 600, and the buffer protection layer 300 and / or the electrostatic treatment layer 200 are positioned relative to the carton 900 through the shaping frame 700. The shaping frame 700 can relatively position and support the compression protection layer 100, the buffer protection layer 300 and the carton 900, so that the three can be smoothly and stably shaped with each other, and then the three can stably cooperate to protect the lithium battery in the loading bin 500.

[0034] Specifically, the shaping frame 700 is formed by folding the corrugated cardboard after wax treatment. The compression protection layer 100 is provided with a card slot, and the shaping frame 700 is connected to the card slot and fixed to the compression protection layer 100.

[0035] In certain embodiments, reference Figure 3 , there are multiple shaping frames 700 and they are distributed around the loading bin 500. The shaping frames 700 are provided with multiple positioning arms 750, and each positioning arm 750 is staggered with each other; the buffer protection layer 300 is clamped between two adjacent positioning arms 750, and the pressure-resistant protective layer 100, the shaping frames 700 and the buffer protection layer 300 are tightened and fixed in sequence. The multiple shaping frames 700 can respectively fix the buffer protection layer 300 and the pressure-resistant protective layer 100 relatively from different positions of the buffer protection layer 300, so that the buffer protection layer 300 can not only be firmly installed in the pressure-resistant protective layer 100, but also the position and size of the gap 600 can be determined, so as to facilitate the insertion of the electrostatic treatment layer 200 in the gap 600 and perform the electrostatic treatment operation.

[0036] Specifically, the shaping frame 700 is a cross-shaped structure, the four positioning arms 750 are staggered with each other, and the corner of the buffer protection layer 300 is clamped between two adjacent positioning arms 750.

[0037] In certain embodiments, reference Figure 4 The electrostatic treatment layer 200 is provided with a clamping structure 270, and the electrostatic treatment layer 200 is clamped with the positioning arm 750 through the clamping structure 270. The clamping structure 270 can stably install the electrostatic treatment layer 200 in the gap 600, thereby preventing the electrostatic treatment layer 200 from shaking and falling off during the transportation and handling of the carton 900, thereby ensuring that the electrostatic treatment layer 200 can smoothly and stably perform the static removal operation.

[0038] In certain embodiments, reference Figure 5The clamping structure 270 includes a positioning slot 275 and a positioning step 273. One of the two interlaced positioning arms 750 extends into the positioning slot 275, and the other of the two interlaced positioning arms 750 abuts against the positioning step 273. After the positioning slot 275 and the positioning arm 750 are mutually clamped, the electrostatic treatment layer 200 can be preliminarily positioned and connected with the pressure-resistant protective layer 100 through the shaping frame 700. In addition, the positioning step 273 will be further positioned with the other positioning arm 750, so that the shaping frame 700 and the electrostatic treatment layer 200 can be positioned and connected in multiple directions, thereby effectively improving the installation stability of the electrostatic treatment layer 200.

[0039] In certain embodiments, reference Figure 3 There are at least four positioning arms 750, at least two positioning arms 750 cooperate with the pressure-resistant protective layer 100 to surround the side of the grounding terminal 800, and the electrostatic treatment layer 200 extends from the top of the grounding terminal 800 to contact the grounding terminal 800. Two of the four positioning arms 750 are used to clamp and fix the electrostatic treatment layer 200, and the other two of the four positioning arms 750 can surround and protect the grounding terminal 800. As a result, the electrostatic treatment layer 200 and the grounding terminal 800 can be positioned with each other through the shaping frame 700, thereby ensuring that the electrostatic treatment layer 200 and the grounding terminal 800 can be smoothly contacted and electrically connected, so as to ensure that the electrostatic treatment layer 200 can smoothly transfer the static electricity in the carton 900 to the grounding terminal 800.

[0040] In certain embodiments, reference Figure 6 , a plurality of reinforcing ribs 150 and a plurality of receiving portions 130 are nested in the compression protection layer 100, and the reinforcing ribs 150 are wavy; each reinforcing rib 150 is stacked in sequence and matched to press against the inner and outer sides of the compression protection layer 100, and the receiving portion 130 is arranged between two adjacent reinforcing ribs 150. The reinforcing rib 150 can effectively increase the structural strength of the compression protection layer 100, so that the compression protection layer 100 has a higher resistance to external impact and collision. The one-to-one cooperation of the plurality of reinforcing ribs 150 and the plurality of receiving portions 130 can further enhance the structural strength of the compression protection layer 100, thereby providing better protection for the lithium batteries in the loading bin 500.

[0041] In certain embodiments, reference Figure 4The electrostatic treatment layer 200 includes a conductive carbon fiber plate, which is installed in the compression protection layer 100 and the buffer protection layer 300; the conductive carbon fiber plate is provided with a plurality of hollow grids 250 and forms a mesh. The conductive carbon fiber not only has high conductivity, but also has the characteristics of corrosion resistance, wear resistance, high temperature resistance, high strength, and light weight. Therefore, it can effectively guide the static electricity in the carton 900 and is not easy to increase the loading burden of the carton 900. The hollow grid 250 allows the conductive carbon fiber plate to form a three-dimensional conductive network, thereby effectively increasing its conductive performance.

[0042] In certain embodiments, reference Figure 7 , a plurality of honeycomb structures 330 are arranged in the buffer protection layer 300, and the honeycomb structure 330 includes a polygonal prism formed by a plurality of plates connected end to end in sequence, and the buffer particles 350 are filled in the polygonal prism to support and shape the polygonal prism. The honeycomb structure 330 can effectively enhance the structural strength of the buffer protection layer 300. When the buffer protection layer 300 is impacted, it will deform and squeeze the buffer particles 350 inside the honeycomb structure 330. The buffer particles 350 will move under the squeezing effect, thereby reducing the impact force borne by the honeycomb structure 330 as a whole, and then the effect of buffering the lithium battery can be smoothly achieved.

[0043] Specifically, the honeycomb structure 330 is formed by bending a cardboard and connecting the end to the end. The buffer particles 350 are degradable corn starch foam particles filled in the honeycomb structure 330, so that the buffer particles 350 can be recycled and degraded.

[0044] In certain embodiments, reference Figure 8 Each honeycomb structure 330 is disposed on the upper part of the buffer protection layer 300, and a support member 390 is disposed on the lower part of the buffer protection layer 300. The support member 390 is an arched folding member and is used to support the honeycomb structure 330. The arched folding member has excellent supporting ability and can also be deformed, so that the honeycomb structure 330 can be effectively supported and buffered, thereby improving the protection effect of the buffer protection layer 300 on the loading bin 500.

[0045] Specifically, the support member 390 is in the shape of an arch bridge formed by folding cardboard, and a shaping member 395 is provided at the bottom of the support member 390. The shaping member 395 presses the bottom of the support member 390, so that the support member 390 is not easily deformed.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
