Abstract: With the implementation of the 25% small offset collision regulations of China-insurance automotive safety index (C-IASI), how to achieve lightweight while improving the collision performance is a common problem and challenge faced by all major Oems. Based on a certain new energy vehicle, this paper finally achieved 25% small-offset collision performance improvement and significant lightweight effect through the application of integral unequal thickness thermoforming door ring. The application of the scheme has a certain reference role for the industry.
