翻背式助老电动床设计与研究

Design and research of an elderly-assisting electric bed

针对当前国内老龄化问题加重,老年人生活自主性较差的问题,设计了一款新型翻背式助老电动床。电动床主要包括升降机构、起背曲腿联动机构、翻背机构。可实现升降、起背曲腿和左右翻背功能,方便不同身高的老年人上下床,帮助老年人更自由地起身、翻背。通过控制电路,实现电动床整体高效运作,并设计监护装置,实时关注老年人的起居状态。分析结果表明,助老电动床升降机构最大加速度约为0.38 mm/s^(2),起背曲腿联动机构最大角加速度约为0.027°/s^(2),翻背机构最大角加速度为0.034°/s^(2)左右,整个运行过程平缓、稳定,符合老年人使用需求。

Aiming at the inconvenience in life of the elderly,we designed a new type of multifunctional electric bed.The electric bed mainly includes a lifting mechanism,a linkage mechanism for raising back and bending legs,and a turning-over mechanism.It can realize the functions of lifting,raising back,bending legs,turning over,and helping the elderly of different heights to get in and out bed.Through the control circuit,the overall efficient operation of the electric bed is realized,and the monitoring device is designed to monitor the living conditions of the elderly in real time.The analysis results show that the maximum acceleration of the lifting mechanism of the electric bed is about 0.38 mm/s^(2),the maximum angular acceleration of the linkage mechanism for raising back and bending legs is about 0.027°/s^(2),and the maximum angular acceleration of the turning-over mechanism is about 0.034°/s^(2).The operation of the bed is gentle and stable,meeting the needs of the elderly.
