1、 摘 要 我国是全球第一 大 玩具生产国，其中机器人玩具一直以来都是儿童 和 成人最受欢迎的产品， 目前市场上的机器人产品要么结构复杂，依靠手动实现变形，要么依靠简单的开式链实现折叠变形，或者不具备变形功能，缺乏使用机构组合变形实现汽车与人形两种构态的机器人玩具。 本设计基于市场已有机械玩具产品分析，将变胞机构理论应用于实际产品开发，创新设计了一款可实现人形行走、汽车构态下遥控驾驶、人形和汽车两种构态相互可逆变形的机械玩具 汽车人。 本作品设计过程的重难点有如下几点：变形六杆机构的尺寸 设计 计算，基于压力角和杆组法理论将六杆机构尺寸算出； 颈部众多零部件的设计与干涉检验；汽车人外形曲面复杂，
2、造型较为困难，运用 Pro/E 高级曲面造型模块进行三维建模与运动 仿真， 通过动态演示发现问题并改进， 最后制作出实物，从而完成本次毕业设计。 关键词 ：汽车人；变胞机构；六杆机构；杆组法； 运动仿真 桂林电子科技大学毕业设计（论文）报告用纸 Abstract China is the worlds largest toy manufacturers, and robot toys have been children and adults most popular products, robotic products currently on the market or the compl
