摘要

随着现代科技的进步，的生活随之变得越来越方便。这直接体现的是生活工具的自动化、智能化。电动折叠轮椅有着方便、省力的特点，也是实现轮椅智能化的基础。我国的人口总量全球最多的国家，老龄化和残疾是要面对的重大问题。随着老年人口比例的持续增加，中国正在迈向老龄化社会，而高龄人群所面临的第一个挑战就是身体机能的衰退，他们的步行能力大大减弱，有些甚至完全失去了步行的能力。另外，交通的四通八达也带来另一个问题交通事故，残疾人数量也急剧增加。

电动折叠轮椅是一种高效、环保的交通工具，它采用蓄电池、电机驱动，可以节省人力、操作简单、行驶平稳，而且噪音低，可以满足居民的出行需求。轮椅由车身、驱动、转向系统及控制系统组成，本论文主要设计轮椅的传动及转向系统，通过自锁电动机带动减速器带动轮椅运动，将驱动与转向集成一体，结构上更加紧凑，轮椅杆加有铰链，方便轮椅折叠放入车厢内，底座安装有电机，方便乘坐者进行旋转。

关键词：电动折叠轮椅驱动系统转向系统
