The invention discloses a vehicle lower vehicle body assembly, a vehicle body and a vehicle, and belongs to the technical field of vehicles, the vehicle lower vehicle body assembly comprises a threshold structure, a cross beam structure, a middle channel structure and a front floor, and a seat front cross beam, a seat rear cross beam and a rear floor cross beam are sequentially distributed between a left threshold beam and a right threshold beam at intervals along the vehicle body of the vehicle from front to back; a middle channel structure arranged in the longitudinal direction of the automobile body is connected with the seat front cross beam, the seat rear cross beam and the rear floor cross beam, and the two sides of the middle channel structure are connected with the left threshold beam and the right threshold beam through connecting parts respectively; when a transverse collision occurs, collision force can be transmitted through the five transverse force transmission paths, the collision force can be dispersed and absorbed easily, the seat front cross beam, the seat rear cross beam, the rear floor cross beam and the front floor rear cross beam are not prone to being bent or broken, the invasion amount of a power battery is reduced, the protection effect on the power battery is improved, and the service life of the power battery is prolonged. Therefore, the safety performance of the vehicle is improved.

    本发明公开了一种车辆下车体总成、车身及其车辆,属于车辆技术领域,车辆下车体总成包括门槛结构、横梁结构、中通道结构和前地板,座椅前横梁、座椅后横梁和后地板横梁沿车辆的车身由前向后依次间隔分布于左门槛梁和右门槛梁之间,并将沿车身纵向设置的中通道结构分别与座椅前横梁、座椅后横梁和后地板横梁连接,且中通道结构的两侧分别通过连接部连接左门槛梁和右门槛梁;在受到横向碰撞时碰撞力会通过5条横向传力路径进行传递,有利于对碰撞力进行分散与吸收,使座椅前横梁、座椅后横梁、后地板横梁和前地板后横梁不容易出现弯折或折断,并减少对动力电池的侵入量,提升对动力电池的保护作用,从而提高车辆的安全性能。
