The invention relates to the field of vehicle body structures, in particular to a front longitudinal beam rear section piece of a vehicle and the vehicle, and aims to solve the problem that collision energy of the vehicle is difficult to transmit to a longitudinal beam, a front longitudinal beam rear end structure and a vehicle body threshold beam in the prior art. In order to achieve the purpose, the front longitudinal beam rear section piece of the vehicle comprises a positive force transmission part, and a front longitudinal beam, the positive force transmission part and a middle channel are sequentially connected in the length direction of the vehicle; and the two side force transmission parts are symmetrically arranged on the two sides of the front force transmission part in the width direction of the vehicle, one ends of the side force transmission parts in the width direction of the vehicle are connected with the front force transmission part, and the other ends of the side force transmission parts are connected with the A column lower inner plates and the threshold beams on the corresponding sides. Collision energy can be transmitted to the A column lower inner plate, the doorsill beam and the middle channel, the number of parts is reduced, the manufacturing cost is reduced, the process complexity of vehicle connection manufacturing is reduced, and the transmission efficiency of the collision energy is improved.

    本发明涉及车身结构领域,具体提供一种车辆的前纵梁后段件及车辆,旨在解决现有技术中车辆的碰撞能量难以向纵梁、前纵梁后端结构与车身门槛梁传递的问题。为此目的,本发明的车辆的前纵梁后段件包括:正传力部,前纵梁、正传力部和中通道沿车辆的长度方向依次连接;侧传力部,两个侧传力部沿车辆的宽度方向对称设置在正传力部两侧,侧传力部沿车辆的宽度方向一端与正传力部连接,另一端与对应侧的A柱下内板和门槛梁连接。本发明能够将碰撞能量传递至A柱下内板、门槛梁和中通道,减少了零部件的数量,降低了制造成本,降低了车辆连接制造的工艺复杂性,提升了碰撞能量的传递效率。
