摘　　要：第七届福建省大学生工程训练综合能力竞赛中,"双8"字赛道要求设计制造一种以砝码重力势能为动力源的"双8"字形运动无碳小车。该无碳小车利用重力势能转换为动能驱动行走和转向,并最终实现预定轨道的运动。文中利用凸轮顶杆机构,提出了一种结构简单、易于生产制造的方案,希望为以后相关的比赛提供指导和参考意见。The double 8-shape track of the 7 th Fujian University Engineering Training Comprehensive Ability Competition requires the design and manufacture of a double 8-shape carbon-free trolley with weight gravity potential energy as the power source.The carbon-free trolley converts the potential energy of gravity into kinetic energy to drive walking and steering,and finally realizes the movement of a predetermined track.This paper uses the cam ejector mechanism,and a simple structure and easy-to-manufacture scheme are proposed to provide guidance and reference for future related competitions.
