Description

用于多种康复训练运动的动力输出装置
技术领域
本发明涉及一种用于多种康复训练运动的动力输出装置，属于健身康复设备技术领域。
背景技术
肌力测评与力量训练是医疗康复领域和体育健身领域基本的环节，肌力的精确测量和科学训练对肌肉及运动神经的训练和康复意义重大。施力器作为测量和训练肌力的工具，须具备以下4种训练模式及相关功能。
等长训练模式，即关节保持在一定位置，肌肉通过等长收缩进行测试与训练。等长收缩指肌肉收缩张力与阻力相等时，肌肉长度与关节位置无明显变化。
等张训练模式，即肌肉通过等张收缩进行测试与训练。等张收缩指肌肉收缩张力大于阻力，肌肉长度自由变化，同时使关节运动。
等速训练模式，即测试过程中肢体运动的速度预先设定且恒定不变，而外加阻力是可变的，它会随受试者用力的大小调节阻力，使肌肉张力增高，力矩输出增加，但不产生加速度。
被动训练模式,即施力器带动肢体以恒定速度在指定范围内运动.运动过程中肌肉张力的大小、变化不会改变运动速度。
肌力显示与记录功能,实时显示并记录测试者在不同位置的肌力水平,为评定肌力水平和指定训练计划提供科学依据。
人机交互功能,测试者可了解肌力测试情况,并可自行设定训练速度、组数、运动范围。
系统集成性与兼容性，测试系统可以与各功能配件集成，从而适用于人体多部位的肌力测评和力量训练。
目前，国际上常用的肌力测试系统有Cybex、Biodex、Kin-com、Lido Active。这些测试系统功能完善，但是价格高昂且需要专业人员的操作。而国内的研究人员偏于单个运动模式实现方式的研究，故测试系统的功能不完备，无法全面测试肌力水平和训练肌力。并且国内的产品为单圈有限范围测扭矩，无法适用于多周无线范围测扭矩。
发明内容
为解决现有技术存在的技术问题，本发明提供了一种结构简单，使用方便，成本低，运行可靠，通过编程能够实现多种运动模式的用于多种康复训练运动的动力输出装置。
为实现上述目的，本发明所采用的技术方案为用于多种康复训练运动的动力输出装置，包括支座，所述支座内设置有扭矩测力轴，所述扭矩测力轴的顶部设置有施力臂，所述施力臂上设置有施力手柄，所述扭矩测力轴的底部与减速器相连接，所述减速器的输入轴连接有伺服电机，所述扭矩测力轴与PLC主控系统相连接，所述伺服电机通过伺服驱动器与PLC主控系统相连接，所述PLC主控系统上设置有HMI人机界面。
优选的，所述扭矩测力轴主要由弹性轴、应变片、动滑环和静滑环构成，所述弹性轴通过轴承安装在支座内，所述弹性轴上设置有应变片，动滑环和静滑环套装在弹性轴上，所述动滑环通过螺钉固定在弹性轴上，所述静滑环和弹性轴之间留有间隙，且静滑环与支座连接固定，所述应变片与动滑环导线连接，所述动滑环和静滑环相接触，静滑环通过导线与PLC主控系统相连接。
优选的，所述弹性轴与减速器的输出轴键连接。
与现有技术相比，本发明具有以下技术效果：本发明结构简单，使用方便，采用PLC进行控制，方便编程，能够实现等速运动、等张运动、等长运动、被动运动四种运动模式，从而准确的进行肌力测评与力量训练；同时采用动、静滑环的相互配合，实现信号输出，进而能够实现多周扭矩的测量。
附图说明
图1为本发明的结构示意图。
图2为图1中的A-A剖视图。
图3为本发明的控制原理框图。
具体实施方式
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图1所示，用于多种康复训练运动的动力输出装置，包括支座1，支座1内设置有扭矩测力轴2，扭矩测力轴2的顶部设置有施力臂3，施力臂3上设置有施力手柄4，扭矩测力轴2的底部与减速器5相连接，减速器5的输入轴连接有伺服电机6，扭矩测力轴2与PLC主控系统相连接，伺服电机6通过伺服驱动器与PLC主控系统相连接， PLC主控系统上设置有HMI人机界面。
其中，如图2所示，扭矩测力轴2主要由弹性轴7、应变片8、动滑环9和静滑环10构成，弹性轴7通过轴承11安装在支座1内，弹性轴7上设置有应变片8，动滑环9和静滑环10套装在弹性轴7上，动滑环9通过螺钉固定在弹性轴7上，静滑环10和弹性轴7之间留有间隙，且静滑环10与支座1连接固定，应变片8与动滑环9导线连接，动滑环9和静滑环10相接触，静滑环10通过导线与PLC主控系统相连接，弹性轴7与减速器5的输出轴通过键12连接。
本发明采用ＰＬＣ运行可靠，其模拟量输入口接收来自扭矩测力轴的信号，经过内部编程控制，在速度模式、被动模式下其模拟量输出口向伺服驱动器输出速度信号，在等张模式下其模拟量输出口输出转矩信号，从而驱动电机运行；伺服电机同时具备转矩控制模式与速度控制模式（或转矩控制模式与位置控制模式），满足要求施力器四种模式的要求；扭矩测力轴两端分别与减速器和施力臂刚性连接，用于实时检测动态扭矩并将检测到的转矩值送入PLC的模拟量输入口。减速器用于放大伺服电机的输出转矩。伺服驱动器控制伺服电机旋转，伺服电机通过编码器发送位置反馈信号。PLC向伺服驱动器发送控制信号，伺服驱动器向PLC反馈运行状态。测试者通过HMI设置参数和监控测试状况。
扭矩测力轴采用弹性轴，在弹性轴上通过应变胶粘贴应变片，然后依次安装静滑环和动滑环，动滑环与应变片连接且随弹性轴一起转动，静滑环与动滑环相接触，且固定在支座上，这样通过静滑环能够顺利传递应变片的电信号，传输给PLC，从而实现多周扭矩的测量。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包在本发明范围内。
