摘要
针对智能多功能护理床对舒适性和实用性的需求,设计开发了一种新型床椅一体化多功能护理床。为简化机构、避免抬背机构与床椅机构的干涉,采用转角电机取代了传统的电动推杆。通过人机工程仿真软件对抬背机构进行模拟运动分析,确定了抬背机构转角电机的转矩变化规律以及抬背动作时人体背部相对抬背机构的滑移量,探讨分析了滑移量的3种补偿方案。制作了实验样机对方案的可行性进行了验证。
Aiming at the comfortable and practical demand of intelligent multifunctional care beds,a new multifunctional care bed is designed and developed.To simplify the mechanism and avoid the interference of the carry back mechanism and the bed-chair mechanism,a new motor used to rotate the backrest is adopted to replace the traditional electric push-rod.The simulation analysis of the carry back mechanism is carried out with the ergonomics simulation software,the torque variation law of the new motor and the slippage of the back of the human body relative to the backrest during carry back motion are determined.Three kinds of slippage compensation programs are discussed and analyzed and an experimental prototype is made to test feasibility.
