The invention provides an automobile body collision energy absorption structure of a hydrogen energy automobile. The structure comprises an underframe and two front longitudinal beams. Each front longitudinal beam comprises an energy absorption box, a front longitudinal beam middle section and a front longitudinal beam rear section which are connected in sequence; the rear ends of the two front longitudinal beams are connected to the underframe; an anti-collision beam is connected in front of the two front longitudinal beams; two ends of the anti-collision beam are fixed on the two energy absorption boxes; and a plurality of collapse induction grooves are formed in the two energy absorption boxes and the middle sections of the two front longitudinal beams. The automobile body collision energy absorption structure of the hydrogen energy automobile has the beneficial effects that the energy absorption boxes of the two front longitudinal beams and the middle sections of the two front longitudinal beams are provided with the collapse induction grooves so that an impact force generated during automobile collision can be partially absorbed in a compression mode; and the rear section of the front longitudinal beam can transmit the residual impact force to the underframe so that a passenger compartment is deformed as little as possible, and safety of automobile passengers during automobile collision is guaranteed.

    本发明提供一种氢能源汽车的车身碰撞吸能结构,包括底架和两前纵梁,每一所述前纵梁均包括均依次相连的吸能盒、前纵梁中段和前纵梁后段,两所述前纵梁后端均连接于所述底架上,两前纵梁前方连接有一防撞梁,所述防撞梁两端分别固定于两所述吸能盒上,两所述吸能盒和两所述前纵梁中段上均设有多个溃缩诱导槽,本发明的一种氢能源汽车的车身碰撞吸能结构的有益效果为:两前纵梁的吸能盒及前纵梁中段上设置溃缩诱导槽可将汽车碰撞时的冲击力通过压缩的方式部分吸收;且前纵梁后段可将剩余的冲击力传递至底架上,从而使乘员舱尽可能小的变形,从而保证汽车乘员在汽车发生碰撞时的安全。
