为解决患者久卧病床不能下地行走及老年人腿部康复训练等问题,对油压式腿部康复装置进行设计,并提出两种用于实现腿部康复训练的传动方案。通过对曲柄滑块机构和摇杆滑块机构主要构件进行运动分析,确定主要技术参数,同时对其构件的位移、速度和加速度对比分析,确定摇杆滑块机构为该康复装备的传动机构。最后运用Solid Works建立该腿部康复装置三维装配模型,并对其进行仿真分析。结果表明,所设计的油压式腿部康复装置能实现预期运动目的并满足康复训练要求。
In order to solve the problem that the patient can not walk for a long time and the leg rehabilitation training for the elderly, the hydraulic leg rehabilitation device is designed and two transmission schemes for leg rehabilitation training are proposed. By analyzing the main components of crankshaft slider mechanism and rocker slider mechanism, the main technical parameters are determined, and the displacement, velocity and acceleration of the components are compared and analyzed to determine the rocker slider mechanism as the transmission mechanism of the rehabilitation equipment. Finally, Solid Works was used to build the three-dimensional assembly model of the leg rehabilitation device and to simulate it. The results show that the designed hydraulic leg rehabilitation device can achieve the desired purpose of exercise and meet the rehabilitation training requirements.
