The invention discloses a vehicle impact crumple device. The vehicle impact crumple device sequentially comprises a first combination end part, at least two crumple bodies and a second combination end part; a plurality of crumple elements which are arranged with intervals form into the crumple bodies; toughness of the crumple bodies is different; when a vehicle impact crumple device is assembled to a frame, the crumple body with larger crumple body toughens is closer to the frame compared with the crumple body with smaller crumple body toughness, and accordingly the crumple body with smaller crumple body toughness is firstly impacted and offset large impact energy through crumple deformation when the vehicle is impacted, the crumple body with larger crumple body toughness can absorb energy for twice, the impact force is avoided from directly impacting the frame, vibration generated by the frame is reduced, and safety of passengers inside the frame is improved; the integral vehicle impact crumple device absorb impact energy through crumple deformation and accordingly, the vehicle impact crumple device can be independently assembled to the frame, the frame does not need to arrange crumple space, and the configuration freedom degrees of the vehicle fame and mechanisms inside the frame are improved.
