Abstract: In the highly competitive automotive industry, new energy vehicles have rapidly emerged as a typical representative of new quality productivity. In order to improve product competitiveness and enhance static visual perception quality in the rapidly iterating market of vehicle models, this article takes the appearance design of a domestic new energy vehicle as an example to study the relevant characteristics that affect the static perception quality of the body appearance, with a focus on analyzing the seams and structures that affect the visual perception quality of the body. Analyzing and comparing competitor design schemes, using CATIA software for cross-sectional analysis and annotation, summarizing typical cross-sectional schemes, and conducting specific analysis from three dimensions of "perceived gap, perceived surface difference, and appearance aesthetics", and then summarizing relevant design experience and guidelines to improve the static perception quality of body styling.

Key words: static perceptual quality; seam line; body styling; sectional structure
