Abstract: This paper aims to introduce an innovative connection support structure for battery electric vehicle chassis exhibition equipment, in order to solve the problems faced by traditional manufacturing methods and improve the display effect and cost-effectiveness of chassis exhibition equipment. The method of connecting the complete lower body assembly of a commercial vehicle has the problems of long production cycle, high cost, and poor display effect. In order to overcome these problems, this paper propose a new design scheme based on steel pipe connection support structure. By selecting appropriate strength steel pipe materials, designing steel pipe lengths and bending angles, the support connection between the front and rear axles of the chassis and the lower part is achieved to meet the production and display requirements of the chassis exhibition equipment.
