摘　　要：为了降低护理床的开发周期、实现护理床的订制性设计,基于模块化设计方法,对护理床的机械结构进行了模块划分与功能分析.对下肢运动模块的设计进行了详细阐述,分析了下肢的3种被动运动.提出了护理床下肢机构设计方案,建立了相应的运动数学模型.利用MATLAB对下肢机构的3种运动状态进行了理论分析,并与ADAMS仿真结果进行比较,验证了下肢机构设计的合理性.该下肢机构运动性能稳定,结构合理,充分考虑了患者的下肢辅助锻炼和日常生活需求.In order to reduce the development cycle and customized design of nursing bed, modular partition and function analysis was given out based on modular design. Detailed exposition of the lower limbs mechanism design was carried out. The three passive motions of the lower limbs mechanism were analyzed. A design scheme of lower limbs mechanism was putted forward and the motion mathematical model was established. Theoretical analyses of lower limbs＇ three mo- tion state were outputted by MATLAB. Compared with the simulation of ADAMS, the reason- ability of lower limbs mechanism was made sure. The lower limbs mechanism which fully consid- erate the lower limbs exercise and daily needs have a stable performance and a reasonable struc- ture.
