Body floor assembly and car

Abstract

The invention relates to a body floor assembly and a car. The body floor assembly includes a floor (10), sill beams (20), longitudinal floor beams (30) and reinforcement devices (40) which disperse and transmit concentrated collision force (F) from the sill beams (20) to the longitudinal floor beams (30), and the longitudinal floor beams (30) are connected to the floor (10) and arranged opposite to the sill beams (20). One ends of the reinforcement devices (40) are connected to the sill beams (20), and the other ends of the reinforcement devices are connected to the longitudinal floor beams (30). In the body floor assembly, the reinforcement devices are additionally arranged between the sill beams and the longitudinal floor beams, so that the structural strength between the sill beams andthe longitudinal floor beams is increased; and the reinforcement devices can well transmit and bear the collision force during the side surface column collision of the car, larger deformation of a carbody is avoided, and passenger injury and damage to a battery pack are prevented.

Description

technical field [0001] The present disclosure relates to the technical field of automobile body, in particular, to a body floor assembly and an automobile having the body floor assembly. Background technique [0002] New energy vehicles have become a new direction of my country's automobile development, especially the development of pure electric vehicles is changing with each passing day. The collision safety performance of the battery pack of pure electric vehicles has become the focus of attention. Therefore, how to protect the battery during a collision to avoid accidents such as explosion and fire caused by large deformation has become the focus of the industry. [0003] It is a relatively common form of traffic accident that the side of the car body hits a big tree, a utility pole and other objects on the roadside during driving. Similar conditions are called side column collisions. [0004] Compared with ordinary fuel vehicles, pure electric vehicles have added a hea...

AI Technical Summary

Problems solved by technology

like figure 1 and figure 2 As shown, in the body floor assembly of the electric vehicle in the prior art, there is no reinforcement structure between the sill beam 20 and the floor longitudinal beam 30, and the weak gap between the door sill beam 20 and the floor longitudinal beam 30 will The area will be severely deformed, and the collision force F will be concentratedly transmitted to the floor stringer 30, resulting in excessive deformation of the floor stringer 30, resulting in a large deformation of the battery pack 50 installed on the floor stringer 30 due to direct impact , resulting in the risk of rupture, leakage, etc.
