AI Technical Summary

Technical Problem

In existing technologies, the crossbeams inside the battery pack need to have space reserved during module assembly, resulting in poor bending resistance and affecting overall rigidity and safety performance.

Method used

Design a detachable frame assembly including a first crossbeam and a detachable second crossbeam, which are connected to the frame components via connectors. The second crossbeam has reserved assembly space when not installed, and improves the overall height and bending resistance of the battery pack after installation.

Benefits of technology

This technology improves the bending resistance and overall rigidity of the battery pack's crossbeams without affecting the assembly process, ensuring safety in the event of a collision.

Abstract

The application provides a frame assembly and a battery pack resisting side column impact. The frame assembly resisting side column impact comprises a frame piece, a cross beam assembly comprising a first cross beam and a second cross beam, the first cross beam being arranged on the frame piece and being located above the second cross beam along the thickness direction of the battery pack, and a connecting assembly comprising a first connecting piece, the second cross beam being detachably arranged on the frame piece through the first connecting piece. The application can make the battery pack cross beam have good bending resistance while meeting normal assembly.
