The invention provides an anti-collision energy-absorbing structure at the front end of an automobile and the automobile thereof.The anti-collision energy-absorbing structure is arranged in a forecabin of the automobile and comprises a front anti-collision beam assembly, a rear anti-collision beam assembly and a rear anti-collision beam assembly, the Shotgun assembly is used for improving the side edge strength of the automobile; the auxiliary anti-collision beam assembly comprises an auxiliary anti-collision beam and an energy absorption box; wherein a first connecting piece is arranged on the auxiliary anti-collision beam and connected with the front anti-collision beam, a second connecting piece is arranged on the energy absorption box and connected with the Shotgun assembly, and the auxiliary anti-collision beam is arranged above the front anti-collision beam and used for reducing deformation of a passenger compartment during automobile collision. The auxiliary anti-collision beam is connected with the front anti-collision beam assembly through the first connecting piece, meanwhile, collision borne by the front end of an automobile is shared, energy absorption of the initial section can be increased, and deformation of a passenger compartment is reduced. Meanwhile, as the auxiliary anti-collision beam assembly is arranged in the front cabin of the automobile, the energy absorption of the front end of the automobile is increased, the energy absorption requirement of the rear part of the cabin can be reduced, and the purpose of light weight of the whole automobile is achieved.

    本发明提供了一种汽车前端的防碰撞吸能结构及其汽车,防碰撞吸能结构设置于汽车的前舱内,包括:前防撞梁组件,用于汽车的前端防撞;Shotgun总成,用于提升汽车的侧边强度;以及副防撞梁组件,包括副防撞梁以及吸能盒;其中,副防撞梁上设有第一连接件与前防撞梁连接,吸能盒上设有第二连接件与Shotgun总成相连接,副防撞梁设置于前防撞梁的上方,用于减少汽车碰撞时乘员舱的变形。副防撞梁通过第一连接件与前防撞梁组件相连接,同时分摊汽车前端所受碰撞,能够增加初段的吸能,减少乘员舱变形;同时由于副防撞梁组件设置在汽车的前舱内,增加了汽车前端的吸能,因而能够减少机舱后部吸能需求,进而实现整车轻量化的目的。
