Description
Technical Field
[0001] This utility model relates to a battery tray structure, specifically a battery tray structure for a lithium battery packaging box. Background Technology
[0002] Lithium batteries typically include lithium metal batteries and lithium-ion batteries. A lithium battery consists of multiple battery cell modules. Existing lithium batteries are widely used in the new energy industry, including new energy vehicles. After the lithium batteries are manufactured and processed, they need to be packaged and transported. Lithium battery packaging boxes are packaging containers used to hold lithium batteries. They are usually cardboard boxes, plastic boxes, or metal boxes with cushioning materials (such as foam and separators) inside. Their protective function is to prevent the batteries from being squeezed, bumped, moist, or subjected to static electricity interference during transportation.
[0003] Battery trays are typically used to support batteries. Multiple dividers are installed inside the trays to facilitate the orderly placement and stable transport of battery products. After the battery unit modules are placed on the trays, the trays are then stacked inside packaging boxes for transport.
[0004] Currently, the internal separators of the battery tray are usually designed, welded, and riveted as a single piece. The above-mentioned integrated design of separator and battery tray can improve the stability of the separator, but the separator cannot be disassembled. However, when the battery module needs to be disassembled, the entire battery tray needs to be replaced.
[0005] Some battery trays use bolts to fix the internal partitions. While bolts allow for removability, disassembly requires rotating multiple bolts, making it inconvenient to remove the battery modules. Furthermore, because different battery products have different sizes, the number of internal partitions needs to be adjusted to accommodate different sized battery modules. The installation position of the partitions also needs to be adjusted according to the number and size of the battery modules. Bolting requires pre-drilled threaded holes, resulting in a fixed position for the partitions and preventing adjustment. This makes the trays non-universal, requiring custom molds for each battery product's specifications, significantly increasing development costs.
[0006] The existing battery trays have partitions that are inconvenient to disassemble, and the number and position of the partitions are fixed. This makes the trays non-universal and requires custom mold manufacturing for each battery product, which greatly increases development costs. Summary of the Invention
