改进了保险杠吸能盒、保险杠后端抗弯部件等关键吸能部件的结构；增加了乘员舱区域部件的强度。
The structures of some key energy-absorbing components were improved, such as the bumper absorbing box and bumper back-end, with the component strength being increased in the cabin part.
折弯部分采用不同速比同步轮传动，减震好，重复精度高从根本上解决了因厚度不均匀而导致弯曲精度。
Using different synchronous wheel drive in the bending unit, good shock absorption, high repetition accuracy, solves the bending precision problem caused by uneven thickness fundamentally.
