Abstract

The invention relates to a doorsill longitudinal beam, an electric automobile body frame and an electric automobile. A first extrusion part in the doorsill longitudinal beam horizontally faces a floor cross beam, so that stable and uniform force transmission of side collision or column collision is ensured, the intrusion amount of a battery pack between two side edge beams is reduced, the battery pack does not bear the force transmission requirement of the side column collision at all, force transmission is completely borne by the vehicle body, so that the maximum arrangement space is provided for a battery core body; in addition, due to the fact that an installation gap is formed between the lower portion of a longitudinal beam inner plate and a side edge beam so as to install a pipeline connecting the front portion and the rear portion of the vehicle body, a middle channel can be omitted in the design process, and the riding experience of the whole vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle body structure design, in particular to a door sill longitudinal beam, an electric vehicle body frame and an electric vehicle. Background technique [0002] The battery life of pure electric vehicles has always been a topic of concern to customers and car companies. CTP battery packs are widely used in the development of electric vehicles because they can accommodate more power in a unit space. In order to increase the energy density of the battery as much as possible and reduce the cost per unit weight and unit volume of the battery pack, the CTP battery pack even cancels or cuts the middle frame structure in order to accommodate more batteries. However, due to the characteristics of the battery pack, it is necessary to ensure that the intrusion of the battery cells is within the specified range during the vehicle collision, so as to prevent the battery from leakage and fire due to the c...
