Embodiment Construction

[0074] 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.

[0075] 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, 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, and the side pointed by the arrow is "right". ", otherwise it is "left"; the Z direction is the up and down direction of the vehicle, where the side pointed by the arrow is "up"...

Abstract

The present disclosure relates to a vehicle body structure and a vehicle. The vehicle body structure includes a front longitudinal beam, a front cabin cross member, a floor panel and a front cross member. The longitudinal beam has a main body section and a downwardly curved section connected to the rear end of the main body section, and the front cabin cross member is connected to the downwardly curved section of the left front longitudinal beam and the right front longitudinal beam and is at least partially located on the Below the main body section, the floor panel is located behind the front cabin crossbeam, the front crossbeam is connected with the front longitudinal beam, and the middle part of the floor panel protrudes upwards to form a central channel extending in the front-rear direction. A central tunnel cover is fixedly attached to the upper surface of the floor panel, and the central tunnel cover at least partially covers the central tunnel. Therefore, the strength and stability of the vehicle body structure during a frontal collision can be effectively improved, so that the collision safety of the vehicle is higher.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle body structures, and in particular, to a vehicle body structure and a vehicle having the same. Background technique [0002] Minimizing the fatality and injury of occupants in traffic (collision) accidents of vehicles, especially passenger cars, is the core design technology for the development and manufacture of passenger cars. 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 an...
