AI Technical Summary
After the existing frame subframe uses profiles for the longitudinal beam, the collision effect of the entire vehicle is poor, making it difficult to effectively protect the battery.
Cross beams and longitudinal beams are made using round or square tube profiles, and the combined structure of curved beams and rear-mounted cross beams is added to increase the connection points, and the connection strength is improved by using the second-conservation welding connection to achieve orderly collapse and energy absorption.
Improves the protection effect during collision, ensures battery safety and reduces development costs.
