Description

Technical Field

[0001] The utility model belongs to the technical field of new energy battery transportation vehicles, and specifically relates to a freely movable and adjustable PACK vehicle. Background Art

[0002] Battery pack PACK is a manufacturing process for lithium-ion batteries. Battery PACK generally refers to a combined lithium-ion battery pack, including packaging, encapsulation and assembly. Common battery PACKs are rectangular. Since PACKs are designed and customized according to customer requirements, PACKs have a variety of different sizes. When PACKs are transported and circulated on and off-site, turnover carriers are required for storage and transportation. During transportation, in order to avoid collision damage to PACKs, PACKs need to remain stable with the carriers. To achieve this goal, existing turnover boxes or turnover racks are generally designed with linings or cushions inside to accommodate PACKs and clamp PACKs. However, due to the large number of PACK sizes, especially for large-sized PACK products, ordinary linings cannot meet the universal requirements of multi-sized PACKs. Therefore, it is necessary to design a carrier that can meet the transportation of a variety of PACK products on and off-site. Utility Model Content
