Vehicle body and vehicle

Abstract

The invention discloses a vehicle body and a vehicle. The vehicle body includes a doorsill boundary beam outer plate, a doorsill boundary beam inner plate and a seat outer side installation support, wherein the upper end of the doorsill boundary beam outer plate is connected with the outer side face of a main plate body of the doorsill boundary beam inner plate; the outer end of the seat outer side installation support is connected with the inner side face of the main plate body of the doorsill boundary beam inner plate; and the doorsill boundary beam outer plate is a metal part. According tothe vehicle body, by redesigning the connecting position of the doorsill boundary beam outer plate and the doorsill boundary beam inner plate, the force transmission path of side collision force can be optimized, the invasion amount of the doorsill boundary beam outer plate and the B pillar reinforcing plate into the vehicle in the side collision process can be reduced to a certain extent, and theinternal space of the vehicle after collision can be increased.

Description

technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to a vehicle body and a vehicle with the vehicle body. Background technique [0002] At the sill of the body, usually the inner side of the side wall outer panel, the upper end of the door sill side beam outer panel, and the upper end of the door sill side beam inner panel form the first three-layer welded structure, the inner side of the side wall outer panel, the door sill edge The lower end of the beam outer panel and the lower end of the door sill side sill inner panel form a second three-layer welded structure, and the middle part of the door sill side sill inner panel is welded and connected with the front seat outer mounting bracket. In the event of a side collision, the force is transmitted from the first three-layer welded structure and the second three-layer welded structure to the middle of the inner panel of the door sill side beam in two ways, ...

AI Technical Summary

Problems solved by technology

[0003] In the process of realizing the present invention, the inventors found that, due to the large gap in the Z direction between the first three-layer welded structure and the mounting bracket on the outside of the front seat during the force transmission process, the collision The force will generate shear force, which will cause the first three-layer welded structure to move too much into the car, and the door sill side beam will be deformed or turned inward, resulting in too much intrusion of the B-pillar reinforcement plate into the car, threatening the driver Safety
