Problems solved by technology

Furthermore, in electric vehicles, due to the need to arrange energy storage battery packs, a large amount of space under the vehicle body is occupied, and various classic body collision safety structure technologies of traditional fuel vehicles cannot be used. It is imperative to arrange a new body structure technology that can satisfy vehicle safety

Embodiment Construction

[0081] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0082] In the present disclosure, unless stated otherwise, the orientation words used such as "up, down, left, right, front, and rear" are defined based on the up-down direction, left-right direction, and front-rear direction of the vehicle, Specifically, in the accompanying drawings, the X direction is the front and rear direction of the vehicle, that is, the longitudinal direction of the vehicle, wherein the side pointed by the arrow is "front", and vice versa is "rear"; the Y direction is the left and right direction of the vehicle, that is, the direction of the vehicle. Horizontal direction, where the side pointed by the arrow is "right" and vice versa "l...

Abstract

The present disclosure relates to a vehicle body structure and a vehicle. The vehicle body structure includes two sill inner panels arranged at intervals along the left and right directions, two reinforcing longitudinal beams arranged at intervals along the left and right directions, and at least one reinforcing crossbeam, each reinforcing longitudinal beam is connected to the corresponding sill inner panel, each The reinforcing beam is connected to the two reinforcing longitudinal beams. When the vehicle collides with the side pillars, the sill support structure formed by the reinforced beam and the reinforced longitudinal beam can not only effectively improve the strength of the body structure, but also transmit the collision force directly from the sill inner panel on one side to the sill inner panel on the other side. The door sill inner panel can significantly reduce the lateral deformation of the floor panel and the door sill inner panel, preventing occupant injury and damage to the battery pack arranged under the floor panel.

Description

technical field [0001] The present disclosure relates to a vehicle body structure, and also relates to a vehicle having the vehicle body structure. Background technique [0002] In vehicle (especially passenger car) traffic (collision) accidents, minimizing occupant fatality and injury is the core design technology of vehicle development and manufacturing. Among them, the design of the crash safety deformation structure of the body structure is the basis for improving the crash safety performance of the vehicle. In order to meet the public's higher and higher collision safety requirements for domestic passenger cars, in recent years, the relevant departments of various countries have gradually improved and supplemented the collision safety of some passenger cars in their relevant laws and evaluation specifications. performance test conditions. For example, the United States is updating its series of regulations and evaluation standards on safety collision performance for v...
