The invention relates to a rear auxiliary frame and a vehicle with the rear auxiliary frame, and belongs to the technical field of automobiles. The number of the longitudinal beams is two, the longitudinal beams are distributed in a bilateral symmetry mode, the front ends of the longitudinal beams are integrally formed on the side wall of the front cross beam, each longitudinal beam comprises a front section, a rear section and a middle weakening section located between the front section and the rear section, and the sections of the front sections and the rear sections are gradually reduced in the direction towards the middle weakening sections; the rear cross beam is parallel to the front cross beam, and the two ends of the rear cross beam are integrally formed on the side walls of the rear sections of the two longitudinal beams respectively; and the inducing groove is formed in the middle weakening section, so that the middle weakening section can absorb energy and break when being impacted. The problems that in the rear collision working condition, especially in the rear-end collision condition of a high-speed rear vehicle, a rear auxiliary frame of a front vehicle subjected to rear-end collision easily moves forwards to invade an oil tank or a battery pack arranged at the front end, fire disasters or explosions occur, and personal safety is threatened in the related technology are solved.

    本申请涉及一种后副车架及其车辆,属于汽车技术领域,该后副车架及其车辆包括前横梁;纵梁,其数量为两个并呈左右对称分布,其前端一体成型在所述前横梁侧壁上,所述纵梁包括前段和后段,以及位于前段和后段之间的中间弱化段,所述前段和后段的截面朝中间弱化段的方向逐渐缩小;后横梁,其与所述前横梁相互平行,其两端分别一体成型在两个所述纵梁的后段侧壁上;诱导槽,其设置在所述中间弱化段上,使中间弱化段受到冲击时吸能断裂。解决了相关技术中后碰撞工况,尤其是高速后车追尾情况中被追尾前车的后副车架易出现前移而侵入布置在前端的油箱或电池包,导致发生火灾或爆炸,威胁人身安全的问题。
