A rear anti-collision beam comprises an outer frame, the outer frame comprises a first transverse plate (21), a second transverse plate (22), a vertical mounting plate (30) and a vertical stress plate (40), the first transverse plate (21) and the second transverse plate (22) are oppositely arranged, the mounting plate (30) is arranged between the first end of the first transverse plate (21) and the first end of the second transverse plate (22), and the stress plate (40) is arranged between the second end of the first transverse plate (21) and the second end of the second transverse plate (22). And the stress plate (40) is provided with a sunken structure which is sunken towards the mounting plate (30). The bending resistance of the rear anti-collision beam of the vehicle is improved from the structural aspect by utilizing the characteristic that the section of the extrusion process is variable; the weight increment is avoided while the collision performance is ensured; compared with the prior art, better bending resistance can be obtained without influencing the surrounding space and increasing the weight; the height and the width of the n-shaped feature can be matched and adjusted according to the requirements of specific vehicle types, and the generalizability is high.

    一种后防撞梁,包括外框,外框包括第一横板(21)、第二横板(22)、竖向的安装板(30)和竖向的受力板(40),第一横板(21)和第二横板(22)相对设置,安装板(30)设于第一横板(21)的第一端和第二横板(22)的第一端之间,受力板(40)设于第一横板(21)的第二端和第二横板(22)的第二端之间,受力板(40)设有向安装板(30)凹陷的凹陷结构。利用挤压工艺截型多变的特点,从结构方面增加车辆后防撞梁的抗弯性能;在保证碰撞性能的同时避免增重;相对现有技术,不需影响周边空间及增加重量即可获得更好的抗弯性能;几字型特征的高度宽度可根据具体车型的要求做匹配调整,可推广性高。
