Abstract

The invention relates to the technical field of structural components of electric vehicles, in particular to a doorsill reinforcing plate structure, which aims at solving the technical problems of adapting to the type of electric vehicles and effectively solving the problem of force transmission of collision so as to protect the safety of passengers, and is characterized in that a first end of a through connecting structure is connected with a front floor longitudinal beam; the second end of the through connecting structure is connected with the rear suspension mounting bracket, so that the through connecting structure can transmit collision force in the head-on collision direction when the vehicle is in head-on collision; the first side of the through connecting structure is connected with the front doorsill body and the doorsill rear section, and the second side of the through connecting structure is connected with the front floor panel, the rear floor cross beam and the rear floor longitudinal beam, so that the through connecting structure absorbs side collision energy during side collision of the vehicle; the structure penetrates through the front floor assembly and the rear floor assembly, continuity of a vehicle body structure is guaranteed, and particularly the torsional rigidity and the first-order mode of a vehicle body are improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle structural components, in particular to a door sill reinforcement plate structure. Background technique [0002] Under the current trend, the technology of electric vehicles is developing rapidly. Electric vehicles use batteries as energy sources. Through controllers, motors and other components, electric energy is converted into mechanical energy to move, so as to control the magnitude of the current and change the speed of the vehicle. In the past, the share of electric vehicles was not very high, but the advantages of electric vehicles are also very obvious. In the process of processing, manufacturing and use, it highlights the trend of energy saving and environmental protection, which greatly facilitates short-distance transportation. In the future, for electric vehicles Research and development will be the most important resource and energy saving. [0003] In the prior art, among t...
