Novel front floor system of electric automobile

Abstract

The invention relates to a front floor system of an electric automobile, which comprises a front floor, a front floor lower crossbeam assembly, a front floor left longitudinal beam assembly, and a front floor right longitudinal beam assembly, wherein the front floor, the front floor lower crossbeam assembly, the front floor left longitudinal beam assembly, and the front floor right longitudinal beam assembly are welded together to form a box structure on which a battery tray can be installed; a crossing type reinforcing structure formed by a front floor left front crossbeam assembly, a front floor right front crossbeam assembly, a front floor left rear crossbeam assembly, a front floor right rear crossbeam assembly, a floor lower reinforcing part and a front and rear floor connecting piece is arranged in the box structure. The front floor system greatly enhances the strength for installing the frame of a battery assembly, solves the problems in the prior art, such as fatigue of a metal plate and battery falling caused by the instable structure of a floor system and the excessive weight of a battery, and meanwhile meets the requirements for installation of a heavier storage battery assembly, and promotes the cruising capability of the electric automobile.

Description

technical field [0001] The invention belongs to the field of auto parts, in particular to a novel electric vehicle front floor system. Background technique [0002] At present, the car body floor structure is generally composed of a front floor (also known as a main floor) assembly and a rear floor assembly. The floor structure is mostly a gasoline vehicle structure. The floor design of this structure does not consider the installation of power batteries. Relatively speaking, the layout of the skeleton structure is unreasonable, and the floor strength and space are insufficient. As a result, the installation of the battery box cannot be realized on the original gasoline vehicle structure. Meet the needs of electric vehicle power chassis system. However, in the design of the front floor system structure of electric vehicles, the front floor structure of gasoline vehicles is borrowed too much, which will lead to low strength of the frame used to install the battery assembly, ...

AI Technical Summary

Problems solved by technology

The floor structure is mostly a gasoline vehicle structure. The floor design of this structure does not consider the installation of power batteries. Relatively speaking, the layout of the skeleton structure is unreasonable, and the floor strength and space are insufficient. As a result, the installation of the battery box cannot be realized on the original gasoline vehicle structure. Meeting the Demands of Electric Vehicle Power Chassis Systems

However, in the design of the front floor system structure of electric vehicles, the front floor structure of gasoline vehicles is borrowed too much, which will lead to low strength of the frame used to install the battery assembly, and the instability of the floor system structure. The number of batteries is small, and the endurance of electric vehicles is poor; when the weight of batteries is too large, it is easy to cause sheet metal fatigue and battery shedding, which reduces the safety performance of the vehicle
