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

[0080] 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.

[0081] 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, where the side pointed by the arrow is "right", and vice versa "left"; the...

Abstract

The present disclosure relates to a body structure and a vehicle. The body structure comprises two front longitudinal beams spaced apart in the left and right directions, two floor longitudinal beamsspaced apart in the left and right directions, two rear longitudinal beams spaced apart in the left and right directions, and a front cross member. When the vehicle body structure is hit forward or backward, the collision force is transmitted in the following order: the front longitudinal beams-the front cross member-the floor longitudinal beam-the rear longitudinal beams. By adopting the technical proposal, the vehicle body structure of the invention can better realize the transmission and dispersion of the collision force when the vehicle body structure is subjected to the front collision orthe rear collision, thereby reducing the deformation of the vehicle body structure and reducing the possible injury to the occupants.

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...
