摘　　要：随着中国保险汽车安全指数(C-IASI)25%小偏置碰撞法规的实施,如何在提升碰撞性能的同时实现轻量化是各大主机厂共同面临的问题和挑战。文章基于某款新能源车型,通过应用整体式不等厚热成型门环,最终实现25%小偏置碰撞性能提升和明显轻量化效果,方案应用对于行业有一定借鉴和参考作用。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.
