摘　　要：目前,我国儿童乘员乘车安全的问题非常严峻,很多市售汽车儿童安全座椅(儿童乘员约束系统)并不能减少儿童在碰撞过程中受到的伤害。为适应较长的儿童成长阶段,并且兼顾结构可行性、碰撞安全性和乘坐舒适性,故选择开发满足0~18kg体重、0~4周岁婴童乘坐需求的0+&I组汽车儿童安全座椅较为合适。将儿童安全座椅产品定位为汽车零部件,遵从欧洲ECE R44 104法规和我国GB27887-2011标准,采用汽车零部件开发流程及质量规范,在市场分析和功能定义的基础上,进行结构方案设计。通过DMU运动分析、FEA仿真计算、碰撞试验不断优化结构,使得最终上市的产品集抗翻转、高度调节和定位指示等功能于一体,符合人体工程学和安全要求。Nowadays, the safety problem of children riding was very severe in our country, many child car seats (CRS) on sale were unable to reduce the injuries for children during collisions. Considering the whole children growth period applicability, collision safety, riding comfort and structural feasibility, it was more suitable to develop the 0+&I group child seat, which could meet the needs of child at 0~18 kg weight and 0~4 years old. As auto parts, the child car seat products conformed to European ECE R44 104 regulation and Chinese GB 27887-2011 standard, and adopted the auto parts development process and quality specifications.The structure design was based on marketing analysis and function definition. Through DMU analysis, FEA simulation calculation and collision test, constantly optimized the structure, the final product integrated with flip resistance, height adjustment, location indicating and some other functions, which met ergonomics and safety requirements.
