轮椅是老年人和下肢残障人士最重要的代步工具。目前,手动轮椅没有外部动力,适合室内或短距离运动;电动轮椅不可拆卸体积庞大,适合室外长距离行走。将研发一种组合型电动轮椅车头,此轮椅车头配合普通手动轮椅使用,可实现手动轮椅电动化,手动电动双模式切换使用。车头回转半径小,安装拆卸方便。使用状态时,可根据手动轮椅的型号和使用者的需求,调整该车头的高度、宽度、角度,实现通用性与舒适性。在该车头与手动轮椅分离后,各模块可拆分,方便外出携带。
The wheelchair is the most important means of transport for elderly and the disabled lower limb. At present, the manual wheelchair is lack of power, suitable for indoor or short distance movement; electric wheelchair is undetachable and huge, suitable for outdoor long distance movement.
