The research and development of automotive battery packs has become a hot topic, and their production and demand are also increasing.

[0003] As a key component of electric vehicles, the battery pack's main structure consists of a housing and multiple battery cells housed within it, with the housing primarily serving as a protective shield. Existing battery pack housings are mostly box-shaped, with ribs positioned inside the housing to cushion the impact of the battery pack. However, due to the narrowness of the ribs, vibrations can impact the sides of the battery cells, damaging the cells and impacting the battery pack's lifespan. Furthermore, existing battery pack housings hold the battery pack together as a single unit during installation, while the spacing between the partitions within the housing is small, making collisions with the battery pack more likely and inconvenient. Therefore, the inventors believe it is necessary to design an automotive battery pack housing that is easy to install and provides a good cushioning effect. Utility Model Content
