The invention relates to the technical field of vehicle buffering, in particular to an automobile impact buffer which comprises a bearing type frame, the bearing type frame comprises a cross beam and a longitudinal beam, a buffer frame plate is installed on the longitudinal beam of the bearing type frame, and a first-stage buffer assembly used for buffering the inner side of the cross beam is arranged on the outer side of the buffer frame plate. A second-stage buffering assembly is arranged on the inner side of the buffering frame plate, the supporting strength of the second-stage buffering assembly is larger than that of the first-stage buffering assembly, and the second-stage buffering assembly is used for buffering impact force exceeding the buffering stroke of the first-stage buffering assembly. And two groups of lateral buffering assemblies for buffering the side surfaces of an impact object penetrating through the cross beams are arranged on the longitudinal beams of the bearing type frame. Through the arrangement of the lateral buffering assembly, when a vehicle collides with an object and the object penetrates through the cross beam of the bearing type vehicle frame and intrudes into a vehicle body, the lateral buffering assembly can be automatically started to clamp the object from the two sides, the buffering contact face with the object is enlarged, and the situation that the object intrudes into a battery bin to cause a major accident of fire is avoided.
本发明涉及车辆缓冲技术领域,特别是涉及一种汽车撞击缓冲器,包括承载式车架,承载式车架包括横梁和纵梁,承载式车架的纵梁上安装有缓冲架板,缓冲架板外侧设置有用于对横梁内侧缓冲的一级缓冲组件,缓冲架板的内侧设置有二级缓冲组件,二级缓冲组件的支撑强度大于一级缓冲组件,二级缓冲组件用于缓冲超过一级缓冲组件缓冲行程的撞击力,承载式车架的纵梁上设置有两组用于对穿透横梁的撞击物体侧面进行缓冲的侧向缓冲组件。本发明通过侧向缓冲组件的设置,在车辆与物体产生撞击,且物体穿过承载式车架的横梁侵入车体内时,能够自动启动来从两侧对物体进行夹持,扩大与物体的缓冲接触面,避免物体侵入到电池仓导致起火的重大事故产生。
