The invention provides a lower vehicle body force transmission structure and a vehicle. The lower vehicle body force transmission structure comprises longitudinal force transmission channels arranged on the left side and the right side respectively, and each longitudinal force transmission channel comprises a front cabin longitudinal beam, a torsion box, a middle channel reinforcing longitudinal beam and a rear floor longitudinal beam which are sequentially arranged in the front-back direction of the whole vehicle; the front part of the front cabin longitudinal beam on each side is bent towards one side outside the vehicle in the left-right direction of the whole vehicle, one side of the torsion box on each side is connected with the threshold beam on the same side, and the other side of the torsion box on each side is connected with the middle channel reinforcing longitudinal beam on the same side; a rear floor middle cross beam is arranged between the rear floor longitudinal beams on the two sides, the rear ends of the middle channel reinforcing longitudinal beams on the two sides are connected to the rear floor middle cross beam, and the middle channel reinforcing longitudinal beam on each side is connected with the rear floor longitudinal beam on the same side through the rear floor middle cross beam. According to the lower vehicle body force transmission structure, the number of the force transmission channels in the lower vehicle body can be increased, transmission and dispersion of collision force of direct collision and rear collision are facilitated, and the safety of whole vehicle collision can be improved.
本发明提供了一种下车身传力结构及车辆,本发明的下车身传力结构包括分设在左右两侧的纵向传力通道,各侧纵向传力通道均包括沿整车前后方向依次设置的前机舱纵梁、扭力盒、中通道加强纵梁和后地板纵梁;各侧前机舱纵梁的前部在整车左右方向上向车外一侧弯折,各侧扭力盒的一侧与同侧的门槛梁相连,各侧扭力盒的另一侧与同侧中通道加强纵梁相连;两侧后地板纵梁之间设有后地板中横梁,两侧中通道加强纵梁的后端均连接在后地板中横梁上,且各侧中通道加强纵梁均通过后地板中横梁与同侧后地板纵梁相连。本发明的下车身传力结构,能够增加下车身中传力通道的数量,有利于正碰及后碰碰撞力的传递分散,可提升整车碰撞的安全性。
