[0002] With the wide application of low speed lithium electricity product in the market, for example, electric tool, low speed electric vehicle, small -size energy storage equipment and so on, the requirement of its packing is increasingly strict, and the traditional packing scheme gradually exposes many technical problems, and it is difficult to meet the demand of modern logistics transportation and product protection.

[0003] In the aspect of the protection performance of packaging, low speed lithium electricity product usually contains precise electronic components and chemical battery assembly, and is sensitive to external force such as vibration, collision, extrusion etc. Traditional packing often adopts simple paper box or foam plastic filling, and the paper box structure is single, and the compression resistance and impact resistance are limited, and the paper box is easily deformed due to extrusion in the transportation process, cannot effectively protect the product from external damage, can cause the shell of lithium electricity product to be broken, internal components to be loose or damaged, and then affect the performance and service life of the product, and even cause safety hazards, such as battery short circuit, fire and other serious consequences. Although foam plastic has certain buffering performance, it has the problems of poor environmental protection and difficult degradation, does not meet the development concept of modern green environmental protection, and its buffering effect is also difficult to continuously guarantee when being used for a long time or subjected to great external force.

[0004] From the structural design of packaging, the traditional packaging lacks the optimization design for the shape, size and mechanical characteristics of low speed lithium electricity product. Many packagings cannot closely fit the product contour, so that the product is easily displaced and shaken in the packaging cavity, increasing the risk of damage in the transportation process. Moreover, some packagings are relatively complex in the assembly process, and a large amount of manual operation and auxiliary materials are required, which not only increases the packaging cost, but also reduces the packaging efficiency, and is not conducive to the demand of large-scale production and rapid logistics distribution. For example, the upper and lower cover structures of some packagings are unstable, and are easily scattered in the stacking storage or transportation process, so that the product is exposed, and the protection effect is lost.
