The invention provides a new energy automobile energy absorption bumper which comprises a support, an outer skin, a stress lever and an energy absorption assembly, the stress lever is formed by hinging a plurality of stress rods end to end, the energy absorption assembly comprises a steel rope, two volute spring boxes and a plurality of guide wheels, the outer skin is fixed to the support, and the outer skin is fixed to the support. A limiting groove is formed in the inner side of the outer skin in the length direction of the outer skin, the stress bar is contained in the limiting groove, the multiple guide wheels and the two volute spring boxes define a ring and are arranged on the support, the steel rope winds around the multiple guide wheels, and the two ends of the steel rope are connected to the output ends of the two volute spring boxes. When the outer skin receives impact force, the impact area extrudes the internal stress rod, the stress rod extrudes the steel rope through the conduction column, the steel rope resets under the action of the volute spring box after being deformed, the force received in the impact direction is conducted to the annular direction of the steel rope in the process, and energy is absorbed and counteracted through the volute spring box. And the conduction column is not in contact with the stress rod after being reset.
本发明提供一种新能源汽车吸能保险杠,包括支架、外蒙皮、受力杠以及吸能组件,所述受力杠由若干节受力杆首尾铰接而成,所述吸能组件包括钢绳、两个蜗卷弹簧盒、若干导向轮,所述外蒙皮固定在支架上,所述外蒙皮的内侧沿着其长度方向设置有限位槽,所述受力杠容置在限位槽内,若干导向轮和两个蜗卷弹簧盒围成环状并设置在支架上,所述钢绳绕过若干导向轮,且其两端连接在两个蜗卷弹簧盒的输出端上。当外蒙皮收到撞击力时,撞击区会挤压内部的受力杆,受力杆通过传导柱挤压钢绳,钢绳变形后会在蜗卷弹簧盒的作用下复位,此过程将撞击方向收到的力传导至钢绳环形方向,并通过蜗卷弹簧盒吸能抵消,且由于传导柱复位后未与受力杆接触。
