摘　　要：因运动、年龄老化等因素导致手指功能损伤患者数量不断增加。针对这类人群进行手指康复器的设计,与传统康复产品相比,具有控制简单、方便、成本相对较低特点。通过分析仿手指运动的自由度,建立了曲柄摇杆机构,可以应用于手指康复器的结构设计;以主要机械构件和手指关节转动角度为参考因素,得出了机构的运动轨迹,在此基础上,得到各机械构件的合理尺寸,从而完成对机械构件的结构设计。通过模拟手指拉伸、弯曲来实现手指的康复功能。通过分析运动的角位移、角速度使得所得的机构更加符合手指的合理运动范围。运动仿真实验表明,该机构能带动手指在一定角度范围进行弯曲拉伸运动,可以满足手指损伤患者的康复训练需求。With exercise,aging and other factors resulting in the number of finger function injury patients increase.The finger rehabilitation device is designed for the crowd.Compared with traditional rehabilitation products,it has the characteristics of simple control,convenience and relatively low cost.By analyzing the degree of freedom of imitation finger movement,the crank rocker mechanism is established,which can be applied to the structural design of finger rehabilitation device.Taking the main mechanical components and finger joint rotation angle as the reference factor,the motion track of the mechanism is obtained.On this basis,the reasonable size of each mechanical component is obtained,so as to complete the structural design of mechanical components.Through the simulation of finger stretching,bending to achieve finger rehabilitation function.By analyzing the angular displacement and angular velocity,the obtained mechanism is more in line with the reasonable motion range of fingers.Motion simulation experiments show that the mechanism can drive fingers to bend and stretch in a certain angle range,which can meet the rehabilitation training needs of finger injury patients.
