电动轮椅设计 ee ( ee) 指导教师: ee [ 摘要]: 文中首先分析了国内外各种轮椅的状况,在对比总结各自优缺点的基础上,由于直流电机的额定输出转矩较低,不足以驱动后轮克服地面摩擦阻力传动,根据国内实际情况,提出了一种含有机械传动减速机构的电动轮椅,基于这种方案,设计了与之相匹配的减速器及其他传动机构,该方案采用直流电机经减速器与链条连接到后轴,以减低输出转速,增大输出转矩。应用现代设计理论及方法、对驱动方式进行分析和再设计,优化车身骨架结构,添加必要的辅助功能装置,利用计算机辅助设计软件构建轮椅及各零部件三维模型,为新型低成本电动轮椅的设计开发打下了一定基础,提供了一种供参考的驱动方案和骨架结构。[ 关键字]: 电动轮椅;设计;机械系统; The design of electric wheelchair ee (ee) Tutor : ee Abstract : This paper first analyzes the domestic and foreign various wheelchair status, based paring the advantages and disadvantages, because the rated output torque DC motor is low, not enough to drive the rear wheel to e the ground friction transmission, according to the actual situation, proposed the electric wheelchair with a mechanical reduction gear mechanism, based on this driving scheme, design of the reducer and other transmission mechanism is matched, the DC motor through reducer and the chain is connected to the rear axle, so as to reduce the output rotation speed, increase the output torque. U se the modern mechanical design theory and method , analyze and re-design the drive mode. Optimize the body frame structure. And add some necessary accessibility devices. puter aided design software to build a three-dimensional model of the wheelchair and it’ponents. This design of the electric wheelchair ’s mechanical systems has lay a certain foundation for the new type low-cost electric wheelchair and has given a reference scheme about drive mode and body frame structure.
