Truss type electric vehicle body structure

Abstract

The invention discloses a truss type electric vehicle body structure which comprises a truss type white body and a vehicle body covering part fixed to the truss type white body. The truss type white body is characterized by being defined by a top cover framework, a lower vehicle body framework, a left side wall framework, a right side wall framework, a front wall framework and a rear wall framework, wherein the left side wall framework and the right side wall framework are symmetrically arranged left and right; the top cover framework, the lower vehicle body framework, the left side wall framework, the right side wall framework, the front wall framework and the rear wall framework are each provided with a self-closed-loop structure. The whole vehicle is formed by mutually connecting aluminum alloy sections and is matched with the carbon fiber composite outer covering part, and the formed vehicle body structure has good light weight performance. The vehicle body is formed by welding the six frameworks, and the welding process of the whole vehicle is optimized. A large number of closed-loop structures are designed between the aluminum profiles, and the bending rigidity and torsional rigidity targets of the whole vehicle are guaranteed. Longitudinal and transverse load transmission paths are reasonable, and the crashworthiness of a vehicle body is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle body structures, in particular to a truss type electric vehicle body structure. Background technique [0002] With the continuous expansion of the automobile consumer market, the resulting environmental protection problems are becoming more and more serious, and the calls for lightweight and electrified automobiles are also getting louder. For the lightweight of automobiles, most enterprises will first think of replacing steel with aluminum alloy. Although the density of aluminum alloy is much lower than steel, its shear strength is correspondingly weaker, and the rigidity of the body cannot be guaranteed. Therefore, how to ensure the lightweight of the automobile body while ensuring its inherent rigidity and strength of joints and fixed points is a technical problem currently faced. Contents of the invention [0003] The purpose of the present invention is to solve the disadvantages of the abo...
