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

摘要： 在竞争极度内卷的汽车行业，新能源汽车作为新质生产力的典型代表快速崛起。为了 在车型快速迭代的市场中提高产品竞争力，提升静态视觉感知质量，文章以某国产新能源车 外观造型为例，对影响车身外观静态感知质量的相关特征进行研究，重点研究分析影响车身 视觉质量感受的分缝和结构。通过分析对比竞品设计方案，利用 CATIA 软件进行断面分析和 标注，归纳典型断面方案，从“感知间隙、感知面差、外观美学”三个维度展开具体分析， 进而总结相关设计经验和准则，提高车身造型的静态感知品质。
