Description

Technical Field

[0001] This utility model belongs to the field of battery module fixing technology, and more specifically, it relates to a high-strength anti-vibration steel strip structure for fixing battery modules of new energy vehicles. Background Technology

[0002] The fixing steel strip for new energy vehicle battery modules is a core mechanical structural component used to rigidly connect multiple battery cells or modules into a battery pack. Its core function is to achieve anti-vibration fixation, thermal management coordination, and electrical connection stability of the battery module through physical constraints. Existing fixing steel strips generally use high-strength cold-rolled steel strips (such as Q235 and 304 stainless steel), with a U-shaped or frame-shaped structure. The ends overlap to form a "steel strip welding area", with an overlap length of ≥20mm and a thickness of 1.5-3mm.

[0003] The existing application number is CN202320075160.7. This utility model discloses an adjustable battery module fixing steel strip, including two steel strip units symmetrically arranged on both sides of the battery module along the cell arrangement direction. Each steel strip unit includes a horizontal segment adapted to the side length of the battery module and two vertical segments connecting the two ends of the horizontal segment; two first connecting members are spaced apart at both ends of the battery module along the cell arrangement direction; the corresponding two vertical segments on the two steel strip units are adjustablely connected through a first connecting member to adapt to battery modules with different end widths; the two steel strip units are spliced ​​together by the two first connecting members to form a closed-loop structure to fix the sides and ends of the battery module.
