AI Technical Summary
The existing full-area foamed battery packs have low structural strength and insufficient bonding strength between the foam and the casing.
A limiting groove is provided on the inner side of the side frame, and the foam layer is filled in the limiting groove. The limiting groove limits and stops the foam layer, thereby increasing the structural strength.
When the battery pack vibrates, the stress on the foam layer can be directly transmitted to the side frame, improving the overall structural strength of the battery pack.
