具有辅助上下床功能助行装置的设计

A Walking Aid with the Function of Assisting in Getting on and Off the Bed

失能老人群体随着人口老龄化、高龄化的加剧,逐渐成为社会关注的焦点,尤其是中轻度失能的老人,该群体多数难以完成站立及行走动作,如上下床、上厕所、室内走动等。根据中轻度失能老人的坐、立、蹲、行等体位转换困难的问题,设计出了一款满足老人上下床和日常活动需求的助行装置,该装置可实现中轻度失能老人独自完成上下床动作,将齿轮齿条机构和人体站立过程中肩部运动曲线相结合,优化出上升机构最佳运动轨迹,实现起卧自由;通过轮毂电机差速原理实现转向,万向轮辅助转向,安全地实现床边、厕所等狭小空间的避障和转向问题。
