Vehicle body floor assembly and vehicle

Abstract

The invention provides a vehicle body floor assembly and a vehicle. The vehicle body floor assembly comprises a floor, a doorsill longitudinal beam and a floor longitudinal beam, wherein the doorsill longitudinal beam and the floor longitudinal beam are fixed to the floor. The connecting piece is fixed to the floor and located between the doorsill longitudinal beam and the floor longitudinal beam; wherein the doorsill longitudinal beam and the floor longitudinal beam are connected through the connecting piece. When side collision occurs, collision force is effectively transmitted to the floor longitudinal beam and the floor through the threshold longitudinal beam, the survival space of a driver and passengers is prevented from being excessively occupied, extrusion of side collision to the battery pack is reduced or avoided, and the side collision safety performance of the whole vehicle is improved.

Description

technical field [0001] This article relates to, but is not limited to, the technical field of vehicles, and in particular, relates to a vehicle body floor assembly and a vehicle. Background technique [0002] Car crash safety performance has received extensive attention, and car crashes are usually divided into frontal, side, rear collisions, rollover and pedestrian collisions. In addition, with the rapid development of the new energy vehicle market, domestic and foreign auto companies have also invested a lot of manpower and material resources in the research and development of new energy and hybrid vehicles. How to ensure the safety of high-voltage batteries and drivers and passengers in different collision areas, especially in side collisions, has become the focus of the market and society. [0003] New energy and hybrid vehicles usually arrange the high-voltage battery under the body floor, which leads to the failure of part of the force transmission path of traditional...

AI Technical Summary

Problems solved by technology

[0003] New energy and hybrid vehicles usually arrange high-voltage batteries under the body floor, resulting in the inability to use part of the force transmission path of traditional models. How to reasonably design the force transmission structure to meet the layout requirements and provide effective protection for the occupants in the vehicle , is a difficult problem for designers

[0004] In side collisions, especially side pillar collisions, new energy vehicles have less space for crushing, and the force transmission path is less or even missing or interrupted. It is difficult to effectively transmit force in side collisions, and the battery pack and internal modules are easily squeezed. Liquid leakage, thermal runaway, etc., resulting in safety accidents
