Design and research of an elderly-assisting electric bed
Aiming at the inconvenience in life of the elderly,we designed a new type of multifunctional electric bed.The e-lectric 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/s2,the maximum angular acceleration of the linkage mechanism for raising back and bending legs is about 0.027°/s2,and the maximum angular acceleration of the turning-over mechanism is about 0.034°/s2.The operation of the bed is gentle and stable,meeting the needs of the elderly.
