The Design and Kinematic Analysis of Multifunction Rehabilitation Bed Based on Double Rocker Mechanism
Abstract
In view of the increasing demand for rehabilitation nursing service resulting from aging population, a new type of rehabilitation bed system is put forward. The main components consisting of double rocker support, auxiliary spring support, back lifting and leg bending mechanisms, and drive device to realize automatic walk and obstacle avoidance, are introduced. Based on the simplified structural model of leg bending mechanism, the kinematic equations are established and solved to analyze and evaluate stability and safety of posture transformation. The different position transformations of virtual prototype are described to illuminate its principle. The bed scheme has characteristics of being compact, multiple function and easy adjustment, aiming to help the patients and olds to live on their own and to promote health recovery.
