Abstract

The invention discloses a lightweighting pure electric automobile body. The lightweighting pure electric automobile body comprises an automobile body framework and a battery pack frame, wherein an outer covering piece, a fender, an automobile body floor, a front bumper structure, a rear bumper structure and an energy absorbing structure are arranged on the automobile body framework; the automobile body framework and the battery pack frame separately adopt an aluminum alloy section space frame structure; and the outer covering piece, the fender, the automobile body floor, the front bumper structure, the rear bumper structure and the energy absorbing structure separately adopt carbon fiber compound materials., The lightweighting and the industrialization requirements of an electric automobile can be met, and besides, integrated design of an automobile body adopting an aluminum alloy frame and distributed carbon fiber integrated structure, capable of improving the safety performance of a high-speed electric automobile is adopted, so that the total mass of the electric automobile is reduced, and the safety performance of the structure of the electric automobile is improved.

Description

technical field [0001] The invention relates to the technical field of pure electric vehicles, in particular to a lightweight body of a pure electric vehicle and a design method thereof. Background technique [0002] Lightweight is the inherent demand for electric vehicles to increase the mileage. The research and application of lightweight pure electric vehicle integrated development technology is the key core technology and competitiveness. The lightweight technology and application of the body is the top priority of vehicle lightweight Heavy. [0003] In terms of the lightweight design of the vehicle structure, electric vehicle platforms are mostly developed on the basis of traditional automobile chassis. The steel battery pack is connected to the underbody of the vehicle body in the form of a suspension structure. The structural design of the battery pack contributes to the weight reduction design of the vehicle body. lower degree. [0004] In terms of lightweight rese...
