Vehicle front floor structure, aluminum alloy extrusion molding part and vehicle

Abstract

The invention relates to a vehicle front floor structure, an aluminum alloy extrusion molding part and a vehicle. The vehicle front floor structure comprises a left doorsill, a right doorsill, and a plurality of cross beams arranged between the left doorsill and the right doorsill; the cross beams comprise at least two first-type cross beams which are arranged at intervals; the at least two first-type cross beams are aluminum alloy extrusion molded parts and are configured to have different cross section shapes; the deformation amount of the left doorsill and / or the right doorsill meets the set requirements when the vehicle is subjected to a side collision impact, and the set requirements comprise the step that a set distance is kept between the left doorsill and / or the right doorsill after deformation and a vehicle part suspended on at least a part of the cross beam. By applying the structure, the strength of the automobile body beam can be remarkably enhanced, the side collision performance of the vehicle is improved, various automobile parts installed on the lower portion of the vehicle body can be protected, and the safety performance of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle front floor structure, an aluminum alloy extrusion molding and a vehicle. Background technique [0002] Various types of automobiles have been widely used in people's daily work and life, and their safety and reliability have increasingly become the focus of attention. However, existing vehicles still have some defects and deficiencies in safety design, which cannot be effectively solved. For example, with the continuous advancement of science and technology, various types of new energy vehicles such as pure electric vehicles and hybrid vehicles are increasingly used in a large number, but these new vehicles may have the disadvantages of light body and insufficient strength. It is difficult to provide effective protection for vehicle components (such as battery packs, etc.) installed in the lower part of the vehicle body, so as to avoid possible further harm to the...

Problems solved by technology

However, there are still some defects and deficiencies in the safety design of existing vehicles, which cannot be effectively solved.

For example, with the continuous advancement of science and technology, various types of new energy vehicles such as pure electric vehicles and hybrid vehicles are increasingly used in a large number, but these new vehicles may have the disadvantages of light body and insufficient strength. It is difficult to provide effective protection for vehicle components (such as battery packs, etc.) installed in the lower part of the vehicle body, so as to avoid possible further harm to the vehicle and personal safety due to damage or destruction of these components.
