多功能电动护理床的研制

Development of Multifunction Electric Nursing Bed

基于人体工学原理和现代机械设计理论,采用机器人化的多自由度结构、多轴协调控制设计多功能电动护理床。床面采用多折床面结构形式,通过按键控制完成平躺、抬背、坐起、屈或伸腿等基本动作,并具有翻身、辅助解便与多轴同步等功能。应用仿真分析技术,优化了多功能护理床的机构,使床的结构符合人体工学原理。设计基于单片机的控制器控制各机构的驱动电动机来满足使用者的功能要求。完成了多功能护理床样机的研制。

A multifunction electric nursing bed has a robotic structure with multiple degrees of freedom, and uses coordinated multi-axis control. The nursing bed is designed based on ergonomic principles and modern mechanical design theories. The bed panel uses a multi-folding structure. Basic movements including lying, back-lifting, sitting up, and leg flexion and extension can be completed through button control. Besides, the bed has various functions such as turning and ex- cretion assistance, as well as synchronization between different axes. Simulation analysis is per- formed to optimize the structure to meet ergonomic requirements. A controller based on a single- chip microcontroller is used to control drive motors of corresponding mechanisms to fulfill func- tional requirements of users. A prototype is developed.
