Vehicle underbody structure
By setting connecting components and a rolling mechanism between the side beams and the curved parts of the vehicle frame, the battery pack is supported to rotate around the rotation axis, which solves the problem of battery pack damage due to torsion and deformation in the frame structure and realizes a safe and efficient configuration of large-capacity battery packs.

AI Technical Summary
Technical Problem
In vehicles with a frame structure, the battery pack is susceptible to damage due to the torsional deformation of the vehicle frame, and existing technologies struggle to effectively mitigate this impact.
Method used
By installing connecting components and a rolling mechanism between the side beams and the curved sections of the vehicle frame, the battery pack is supported and can rotate around the rotation axis, reducing the impact of torsional deformation on the battery pack.
Benefits of technology
It effectively suppresses or avoids the impact of torsion and deformation on the battery pack, ensuring the safety of the battery pack, and enables the configuration of a large-capacity battery pack in a limited space.
