【摘要】 为解决现有护理床器械背板牵扯患者背部衣物而造成其不适难题，设计了一款护联动式理床抬背结构。该机构主要采用联动连杆滑块结构，实现患者起背过程中靠背板跟随患者背部的位姿变化而改变。依据矢量方程建立联动机构运动理论模型，并通过MATLAB仿真模块对联动机构进行了运动仿真实验，实验结果表明：仿真实验数据与理论计算结果整体趋势性较好，验证了结构设计的正确性和可行性。更多还原

【Abstract】 In order to solve the problem of uncomfortable nursing bed in the existing nursing equipment caused by the backboard pulling the patient’s back clothes, a linkage bed back lifting mechanism is designed. The linkage slider linkage mechanism is used to realize the backrest plate following the movement of the patient’s back during the back-up process.The vector equation theoretical model of the mechanism is established, and the motion analysis is performed. Using MATLAB tool simulate the mechanism to verify the rationality of the mechanism plan.更多还原
