Vehicle body of electric vehicle

Abstract

The invention discloses a vehicle body of an electric vehicle, and relates to the technical field of automobile manufacturing. The vehicle body of the electric vehicle comprises a left front longitudinal beam, a right front longitudinal beam and a floor. A floor upper portion left reinforcing longitudinal beam and a floor upper portion right reinforcing longitudinal beam are arranged on the floor. The positions of front seats on the floor protrude upwards to reserve battery pack mounting space. The floor upper portion left reinforcing longitudinal beam and the floor upper portion right reinforcing longitudinal beam turn in the protruding positions and extend to a front seat left rear cross beam and a front seat right rear cross beam. A floor lower portion left reinforcing longitudinal beam and a floor lower portion right reinforcing longitudinal beam are arranged in the positions, corresponding to the floor upper portion left reinforcing longitudinal beam and the floor upper portion right reinforcing longitudinal beam, of the bottom face of the floor correspondingly and are connected with the left front longitudinal beam and the right front longitudinal beam correspondingly. A transverse reinforcing beam is arranged between the floor lower portion left reinforcing longitudinal beam and the floor lower portion right reinforcing longitudinal beam. According to the vehicle body of the electric vehicle, the wide and regular mounting space is provided for a battery pack of the electric vehicle, vehicle body deformation in collision of the electric vehicle is effectively reduced, and the safety of passengers and the battery pack is protected.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, and is a vehicle body structure that facilitates the arrangement and installation of electric vehicle battery packs and can enhance the collision safety performance of the electric vehicle. Background technique [0002] The traditional car body floor structure is generally divided into floor panels and floor skeletons. This floor skeleton frame is composed of multiple beams and longitudinal beams. The frame is basically on the same level, which is a single-layer structure, and the level position is relatively low. . If the power battery is placed under the floor, the ground clearance will be extremely small. If it is placed above the floor, the battery pack will be in the passenger compartment and cannot be effectively isolated from the occupants. Therefore, the body floor of the above structure cannot be directly used in electric vehicles, which will affect the installation of ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide an electric vehicle body, which can solve the problem that the electric vehicle battery pack is difficult to arrange and install, and can effectively reduce the deformation of the electric vehicle body during collision, and protect the safety of the occupants and the battery pack.
