Description

手臂肌力训练复健器材 技术领域
本发明涉及一种肌力训练器材，尤其是关于一种手臂肌力训练复健器材。
背景技术
传统的肌力训练器材或是复健器材，主要利用悬挂重物作为阻力的来源，而近年已发展出利用磁流变液技术的肌力训练或复健器材，其可藉由电流大小来控制阻力输出的大小，此一技术使得肌力训练器材及复健器材的体积及整机重量减少许多。
当肌力训练器材或复健器材已经可利用电流调整阻力时，其带来的优点除了缩小体积与减少整机重量以外，亦可以利用自动重量控制的机制来减少使用者训练或复健时造成的伤害，因此现有利用可变阻力来源的训练器材或复健器材多会配设力传感器来侦测使用者施力的状况，并依据其施力状况来控制阻力输出，例如，现有一种手臂复健器材是以磁流变液作为阻力输出装置，且其于阻力输出装置上设置有力传感器，用以侦测阻力输出及使用者的操作状况，并由主控器依力传感器检测到的数值调整磁流变液装置的输出阻力，如此即可配合各种不同的运用。
然而，由于现有手臂复健器材是将力传感器设置于阻力输出装置，其测量到阻力输出装置的转矩大小，并不一定等于使用者所施予拉动手臂复健器材手把的力量，因此于测量上有相当的误差，精准度低，再者，使用者施与手把拉力之后必须经过阻力器开始转动才能被力传感器测得数据，也有时间延迟的误差，使其应用范围大幅受限，除此之外，由于力传感器设置于阻力输出装置上，加上其精准度较低，设备出厂时，需要拆开整机进行校准，使 用一段时间之后的重新校准也需拆开整机，其校准及维护的工序复杂，因此，现有手臂复健器材仍须改良。
发明内容
有鉴于现有手臂复健器材测量用户施力有时间延迟、精准度较低且硬件校准不易的技术缺陷，本发明提出一种手臂肌力训练复健器材，可避免时间延迟且提高测量精准度，并可提升硬件校准的便利性。
为达上述目的所采用的技术手段是令该手臂肌力训练复健器材包含有：
一本体，其包含有一外壳及一可变式阻力装置，该可变式阻力装置设置于外壳内；
一手把，其包含有一悬臂及一握把支架，悬臂枢设于可变式阻力装置上；
一角度计，设于可变式阻力装置上，以检测手把相对可变式阻力装置枢转角度，并输出一角度信号；
一力传感装置，其设置于手把的握把支架上，并输出一力感测信号；
一主控单元，其与可变式阻力装置、角度计及力传感装置电连接，以接收角度信号及力感测信号，并依据角度信号及力感测信号控制可变式阻力装置的阻力大小。
由于本发明手臂肌力训练复健器材的力传感装置是设置在手把的握把支架上，直接检测使用者手部施力，避免量测时间延迟的问题，且直接测量使用者手部施力大小可提升精准度，而产品出厂校准时，可直接在手把调整力传感装置，不需拆装整机，校准工作较为方便。
而在应用方面，主控单元可配合酌量减重程序，于力传感装置检测用户有施力，但角度计于一固定时间内不再增加时，即判断用户不堪负荷目前重量，进而控制可变式阻力装置减小阻力，另外，由于本发明手臂肌力训练复健器材的力传感器是设置在手把的握把支架上，故可用来直接作为检测使用 者握力的设备，可作为其他不同用途的复健器材，其应用范围更为广泛。

具体实施方式
请参阅图1至图4，本发明的手臂肌力训练复健器材包含有：
一本体10，其包含有一外壳11及一可变式阻力装置12，可变式阻力装置12设置于外壳11内，于本实施例中，本体可视可变式阻力器12的种类而进一步设置齿轮组，其详细技术于后段说明；
一手把20，其包含有一悬臂21及一握把支架22，悬臂21枢设于可变式阻力装置12上；
一角度计30，设于可变式阻力装置12上，以检测手把20相对可变式阻力装置12的枢转角度，并输出一角度信号，于本实施例中，可变式阻力装置12设有减速齿轮组，角度计30设置于减速齿轮组上，若不设置减速齿轮 组者，角度计30可直接设置于可变式阻力装置12枢转轴心上；
一力传感装置40，其设置于手把20的握把支架22上，并输出一力感测信号；
一主控单元50，其与可变式阻力装置12、角度计30及力传感装置电40连接，以接收角度信号及力感测信号，并依据角度信号及力感测信号控制可变式阻力装置12的阻力大小。
本发明利用力传感装置设于手把握把支架上的设计，可直接检测使用者手部施力，得以避免量测时间延迟的问题，且直接测量使用者手部施力大小也可提升精准度，并且可以配合各种不同的施力量测，以下进一步说明。
以下仅进一步说明手把的详细结构，请进一步参阅图5，为进一步提供手把20伸缩的功能，于本实施例中，悬臂21包含一第一臂部211及一第二臂部212，第一臂部211设置于可变式阻力装置12上，手把支架22形成于第二臂部212上，第二臂部212滑设于第一臂部211的一端，并以一固定栓213固定第一臂部211及第二臂部212，如此，即可藉由第一臂部、第二臂部的滑动调整悬臂的长度，并以固定栓相对固定第一臂部、第二臂部，达到调整悬臂长度的功能。
请进一步配合参阅图6，以下进一步说明上述力传感装置40的详细结构，力传感装置包含有一力传感器41、一滑动杆42及一组盖板43，力传感器41检测受外部挤压的力，并输出力感测信号，滑动杆42设置于手把20的握把支架22内，并抵止于力传感器41，组盖板43盖设于滑动杆42外，于受到使用者施予推向滑动杆42的压力后，推动滑动杆42挤压力传感器41，于本实施例中，力传感器具41有一压力检测杆411，滑动杆42则抵止于力传感器41的压力检测杆411上，但不以此为限，若所采用力传感器以其他部件检测压力，则滑动杆抵止于力传感器检测外部压力的构件上。
上述盖板推动滑动杆的机构设计，于本实施例中，是于滑动杆42上固 设一滑动压板421，滑动压板上形成有复数斜角块4211，组盖板43对应滑动压板421处形成有对应的斜角块431，并抵止于滑动压板421的斜角块4211上，以于受到压力后推动滑动压板421，使滑动杆42挤压力传感器41的压力检测杆411。
上述手把的力传感装置所测量到的外部施力，可分别测量使用者的握力及拉动手把的拉力：当使用者紧握手把的握把支架22时，将如图7所示，直接将组盖板43向内挤压，推动滑动杆挤压力传感器的压力检测杆，藉此，力传感器便可检测到使用者手握手把的握力；而当使用者向上拉动手把时，则如图6所示，组盖板43将会由下往上挤压滑动杆42，使得滑动杆42挤压力传感器41的压力检测杆411，此时力传感器41即测得使用者的拉力。
由于本发明手臂肌力训练复健器材将力传感装置40设置于手把，加上上述可测量拉力及握力的设计，故具有较广泛的应用范围，当使用者不拉动手把，而仅紧握手把时，力传感装置设置即可测得用户握力，将本发明用于复健器材，可进一步用来量测、训练使用者的握力，而测量拉力时，要避免握力影响测量精准度时，可如图8所示进一步于手把外部套设一刚性材质的外套筒60，便可隔绝使用者紧握手把的握力，仅能透过拉动手把，使外套筒挤压组盖板，此时，即可专用于测量使用者拉动手把的拉力。
除测量拉力与握力以外，由于本发明手臂肌力训练复健器材将力传感装置设计于手把上，又可作为指力复健的器材，使用上可配合以一拉条一端固定于手腕或手掌，另一端固定于食指(或任一只手指)，并以拉条钩扣于手把的力传感装置40上，以手指拉勾条使勾条带动盖板43的方式测量指力，可用于手指复健。
由于本发明手臂肌力训练复健器材可测量用户拉动手把的拉力，以下进一步说明主动单元配合拉力测量可执行一减重程序，系供默认一标准时间及依标准角度，并于主控单元50接收力感测信号及角度信号后，开始计时该 标准时间，若角度计30输出的角度信号于标准时间内未达到标准角度，则判定为过重，由主控单元自动减少可变式阻力装置12的阻力，例如，当本发明用于肌力训练时，可设定标准时间为2秒，标准角度为N度，当使用者无法于2秒内使手把转动至标准角度时，则主控单元50减少可变式阻力装置12的阻力，如此可避免使用者于训练过程中受伤。
前述实施力是利用套设刚性材质的外套筒60来选择测量握力或拉力，使用时必须套上或取下外套筒60，为进一步提升使用便利性，另一较佳实施例如图9所示，套设一具有磁流变液的外套筒70，外套筒70包含有一可旋转的磁铁片71、一磁铁包覆层72、一磁流变液层73及一软质包覆层74，磁铁包覆层72包覆磁铁片71，且具有一导磁部721及一隔磁部722，导磁部721为高导磁性的材质，隔磁部722为低导磁性的材质，磁流变液层73包覆磁铁包覆层72及力传感装置40的盖板43，且材料为磁流变液材料，软质包覆74层包覆于磁流变液层73外，当使用者要测量握力时，可旋转磁铁片71，使磁极对准隔磁部722，此时，磁力线不通过磁铁包覆层72，磁流变液层73将转为软性材质，使用者手握的握力即可直接传导至力传感装置40的组盖板43，而当使用者要测量拉力时，可旋转磁铁片71，使磁极对准磁铁包覆层72的导磁部721，磁力线通过磁铁包覆层72，使得磁流变液层73转为刚性材质，握力无法传导至力传感装置40，即转为量测拉力的模式。
上述磁流变液功能的外套筒利用磁铁片与具有隔磁及导磁功能的磁铁包覆层控制磁流变液层软化或硬化，亦可利用电磁铁片或电磁线圈取代磁铁片71及磁铁包覆层72。
除上述实施例以外，再请进一步参阅图10，于本实施例中，力传感装置80设置于握把支架22’上，且包含有一力传感器81、一软质握把82、一填充于软质握把82内的磁流变液物质83及一组电磁线圈84，力传感器81同样具有一压力检测杆811，力传感器81及软质握把82设于握把支架22，且 软质握把82内的磁流变液物质83与力传感器81的压力检测杆811接触，电磁线圈84设于软质握把82的内环壁，当电磁线圈通电流时，靠近电磁线圈的磁流变液物质83’变为刚性材质，可阻隔使用者手握软质握把82的握力，而当使用者拉动手把20时，靠近电磁线圈84的刚硬磁流变液物质83’将挤压内部软性的磁流变液物质83，进而挤压力传感器81的压力检测杆811，此时即为拉力检测模式，而当电磁线圈不导电时，所有磁流变液物质83、83’转变为软性材质，使用者握软质握把82的握力即可传递至力传感器81的压力检测杆811，此时为握力检测模式。
上述仅针对手把上力传感装置的设计进行说明，为提升本发明手臂肌力训练复健器材的使用便利性，亦可进一步增加以下设计。
进一步地，外壳侧壁可设置一手靠垫91，以供使用者放置手肘。
进一步地，外壳上可设置一显示屏幕92，该显示屏幕92与主控单元50电连接，以显示用户拉动次数、力度、操作模式及各种警告标语等。
进一步地，外壳底部可设置一固定器93，以将手臂肌力训练复健器材固定于桌面上。
进一步地，可变式阻力装置12可设置一组减速齿轮组13，以供将手把20及角度计30设置于减速齿轮组13上，减速齿轮组的使用与否，可视上述可变式阻力装置12输出阻力大小而定，若所采用的可变式阻力装置12输出阻力较小，则可利用减速齿轮组13来增加阻力，若所采用的可变式阻力装置12输出阻力较大，则可不需使用减速齿轮组，直接将手把20及角度计30设置于可变式阻力装置12的转轴上即可。
再请进一步配合参阅图11，于本实施例中，手把20包含有两个悬臂21及两个握把支架22，两个悬臂21与角度计30一并枢设于可变式阻力装置12上，如此可提供使用者以双手拉动手把20，提供双手臂训练及复健的功能，或两个悬臂21可一者与角度计一并枢设于可变式阻力装置12上，另一 悬臂21枢设于外壳11(或于可变式阻力装置12上设置一固定轴心，使悬臂设置于固定轴心上)上，如此可简化可变式阻力装置12与外部结构链接的结构设计，亦可使二悬臂21稳固固定于本体10上。
上述针对本发明手臂肌力训练复健器材主要机构进行说明，以下仅进一步以图3说明本发明的电路，其中，主控单元50包含有：
一数据收集模块51，与角度计30、力传感装置41的力传感器411及显示屏幕92电连接，并将接收的角度信号及力感测信号数字化；
一服务器52，与数据收集模块51连接，并接收数字化后的角度信号及力感测信号后输出一阻力控制信号，于本实施例中，是以电脑主机作为服务器52，并以通用串行总线(USB)接头连接电脑主机，或可利用笔记本电脑、手机或智能型装置，并利用通用或专属的连接线连接些装置，亦可利用其他可程序化控制芯片，使整机设置于手臂肌力训练复健器材内；及
一可程序化电流控制模块53，与服务器52及可变式阻力装置12电连接，并依据阻力控制信号输出电流，以控制可变式阻力装置12的阻力大小。
进一步地，上述服务器52可具有wifi或蓝牙传输的功能，以与外部智能型装置、电脑主机或其他通讯设备进行数据传输或遥控控制等。
进一步地，上述可变式阻力装置可为定扭力输出的伺服马达，磁粉式或磁流变液阻力装置，或可为其他输出阻力可受到可程序化电流控制模块输出电流控制的可变式阻力装置。
上述本发明手臂肌力训练复健器材，其直接于手把的握把支架上量测握力及拉力的方式，可提升量测精准度并且避免时间延迟的误差，且出厂校正及后续维修校正不需拆开整机，减少校准工序，除此之外，本发明亦提供可在手臂肌力训练或复健的仪器上进一步提供测量手握力、手拉力的功能，并提出实施力配合握力及拉力量测后的减重机制，使得后续可配合其他软硬件的设计，使肌力训练及复健训练具有更广泛的发展空间。
以上所述的实施例仅为本发明的技术思想及特点，其目的在使所属领域技术人员能够了解本发明的内容并据以实施，但不能以此限定本发明的专利保护范围，即凡依本发明所揭示的精神所作的均等变化或修饰，都应属于本发明专利保护范围。
