Abstract: This paper introduces the design of the rear opening console armrest assembly, including the composition of the armrest assembly, the selection of materials, the design of the armrest skin, including the design requirements of the skin stiching, the positioning and design points of the inner and outer panels of the armrest, and introduces the man-machine requirements that the armrest needs to meet in the design process, which can provide a certain reference for the design of the same type of vehicle models; using the finite element analysis software to analyze the strength of a plastic hinge armrest when it is closed and opened, and verify the rationality of the design. Through the analysis results, it can be seen that the design of the armrest meets the requirements of the company's specifications, avoiding the subsequent mold repair costs caused by unreasonable part design.
