Abstract

Provided are a vehicle-body crossbeam and a vehicle body. The vehicle-body crossbeam (200) comprises a grooved crossbeam main body and a support member; the support member is connected to the grooved crossbeam main body and at least partially encloses a support structure having a closed cross-section. The vehicle-body crossbeam has good structural strength and strong impact resistance.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle body structures, and in particular, to a vehicle body cross member and a vehicle having the vehicle body cross member. 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 ...
