 本发明的实施方式
在下文中，仅简单地描述了某些示例性实施例。正如本领域技术人员可认识到的那样，在不脱离本发明的精神或范围的情况下，可通过各种不同方式修改所描述的实施例。因此，附图和描述被认为本质上是示例性的而非限制性的。
下面结合附图对本发明的实施例进行详细说明。
如图1所示，本实施例提供了一种面料湿热性能检测用辅助装置，包括:
工作台100，设有安装架110；
第一面料固定板120，固定设于工作台100上，用于可拆卸固定待测面料400；
第二面料固定板130，固定设于安装架110上，用于可拆卸固定待测面料400；转动件140，竖直式转动连接在上下相对设置的第一面料固定板120和第二面料固定板130之间；
模拟块200，可拆卸连接在转动件140上，且其远离转动件140的侧面设有用于模拟面料使用环境的模拟层210；
转动电机150，与转动件140连接，以驱动转动件140旋转；
其中，当待测面料400通过第一面料固定板120和第二面料固定板130进行固定后，待测面料400、第一面料固定板120和第二面料固定板130之间围成湿热检测腔160，湿热检测腔160配置有用于提供湿热空气的湿热空气供给装置300和用于检测温湿度的温湿度传感器组。
本实施例中，面料湿热性能检测用辅助装置是起辅助作用的，用于模拟待测面料400的使用环境以及提供用于提高检测结果准确的温湿度参考数据（通过温湿传感器组采集），可以理解的是，直接用于检测面料湿热性能的装置可以是织物热阻湿阻测试仪，或现有的其他检测装置，本实施例不再赘述。在实际的检测环境中，本申请实施例公开的面料湿热性能检测用辅助装置与织物热阻湿阻测试仪配合使用，共同检测面料的湿热性能。
值得注意的是，用于模拟面料使用环境的模拟层210随同模拟块200可以可拆卸地拆装，当模拟不同的使用环境时，可以根据待测面料400的使用环境进行材料选型，如待测面料400用于人体，则模拟层210的材料可以选用类似于机器人皮肤的智能泡沫等材料。
在其它的模拟环境中，可能待测面料400还可用于木质环境，则模拟层210的材料可以为相应的木质材料；再比如待测面料400用于金属环境，则模拟层210的材料可以为相应的金属材料；及其它的塑料环境等等，如此类推，只需提前根据待测面料400的使用环境，制作好对应材料的模拟层210即可。
在检测前，通过第一面料固定板120和第二面料固定板130将待测面料400固定，第一面料固定板120和第二面料固定板130的截面形状大致成圆形状，待测面料400、第一面料固定板120和第二面料固定板130之间围成的湿热检测腔160类似一个桶状的结构，通过湿热空气供给装置300向湿热检测腔160通入湿热空气，同时转动电机150启动，转动电机150带动转动件140旋转，转动件140带动模拟层210和模拟块200旋转，从而准确模拟待测面料400在其使用环境时的湿热性能，进而提高检测结果的准确率，保证检测结果准确有效，再通过温湿传感器组进行温湿度检测，为检测结果提供准确的参考数据。
模拟块200的形状和大小是可以改变的，在具体的使用环境中，可以根据面料的使用场合，配置不同型号的模拟块200。当转动件140转动时，模拟块200跟随转动件140在湿热检测腔160中执行转动操作，从而在某些情况可以模拟面料与人体直接接触且存在摩擦的情形，而在一些情况下，又可以模拟面料与人体不接触的情形，故该湿热性能检测用辅助装置适用性更广泛。
为了便于固定待测面料400，在一些实施例中，如图4和图5所示，第一面料固定板120和第二面料固定板130通过魔术贴或磁铁170或卡箍180与待测面料400可拆卸连接。该方案中，通过魔术贴或磁铁170或卡箍180或其它现有的可拆卸连接方式，如在第一面料固定板120和第二面料固定板130上分别设置N极性的磁铁170和S极性的磁铁170，将待测面料400夹在极性相对的2个磁铁170之间，实现固定；又如当第一面料固定板120和第二面料固定板130为圆板时，通过卡箍180及相应的螺栓螺母，将待测面料400的一端夹在卡箍180和第一面料固定板120之间，另一端夹在另一个卡箍180和第二面料固定板130之间，实现固定。
采用上述的固定方式，使得第一面料固定板120和第二面料固定板130可以很方便地拆卸待测面料400，而且因为待测面料400、第一面料固定板120和第二面料固定板130三者之间围成的湿热检测腔160是环形腔体，不需要绝对密封，只需相对密封，甚至不需要密封，也能够很好地模拟出待测面料400的使用环境。
为了准确模拟待测面料400的使用环境，在一些实施例中，如图3所示，模拟块200有多个且尺寸不一，以使模拟块200与待测面料400之间具有间距，或模拟块200与待测面料400相互接触，或模拟块200抵紧待测面料400。该方案中，多个尺寸不一的模拟块200，能够模拟出待测面料400与使用环境不接触、接触及相挤压的真实情况，进一步提高检测结果的准确率；而在实际应用中，模拟块200可以包括半圆柱体或扇形柱体和卡块260，卡块260与转动件140可拆卸连接，半圆柱体或扇形柱体与卡块260固定连接，通过不同半径的半圆柱体或不同弧度的扇形柱体，即可改变待测面料400与使用环境不接触、接触和相挤压的真实情况；在一些实施例中，多个尺寸不一的模拟块200可以同时使用；在另一些实施例中，多个尺寸不一的模拟块200可以替换式使用。在一些实施例中，转动件140可以圆柱体或矩形柱体或五边形及以上的多边形柱体。
为了进一步准确模拟待测面料400的使用环境，在一些实施例中，如图2所示，模拟块200开设有空腔220，空腔220沿模拟层210分布，转动件140开设有第一通道141，湿热空气供给装置300通过第一管道311与第一通道141连通，第一管道311与转动件140转动连接，模拟块200开设有与空腔220连通的第二通道230，当模拟块200与转动件140连接后，第二通道230与第一通道141连通。该方案中，通过湿热空气供给装置300向空腔220内通入湿热空气，可以准确模拟待测面料400的使用环境中的物体由内到外散发的湿热气体，进而准确模拟待测面料400的使用环境，提高检测结果的准确率，特别是能够准确模拟待测面料400用于人体时的环境。
参见图2，在一些实施例中，模拟块200的顶部和底部均开设有弹簧腔240，弹簧腔240内置有弹簧241，所述弹簧腔240滑动连接有凹型块250，凹型块250通过弹簧241可伸缩地滑动在弹簧腔240内外，转动件140的外侧面由外至内依次开设有相连通的第一卡槽142和第二卡槽143，第二卡槽143长度方向的尺寸大于第一卡槽142长度方向的尺寸，以使第二卡槽143在超出第一卡槽142的部分从而形成第三卡槽144，第三卡槽144属于第二卡槽143的一部分，第三卡槽144可以有2个，2个第三卡槽144分别位于上侧和下侧，且2个卡壁与处于正常状态下的2个凹型块250的位置一一相对应，第三卡槽144与凹型块250的一侧凸起相适配，当凹型块250通过弹簧241缩进弹簧腔240内，将模拟块200的卡块260部分依次插入第一卡槽142和第二卡槽143，在弹簧241的作用下，凹型块250与第三卡槽144相嵌，实现模拟块200与转动件140的可拆卸连接；当拆卸时，按下凹型块250裸露在外的部分，即可将凹型块250与第三卡槽144分离，即可将模拟块200拔出。
为了提高温湿度参考数据的可靠性，在一些实施例中，温湿传感器组包括第一温湿度传感器510、第二温湿度传感器520、第三温湿度传感器530、第四温湿度传感器540和第五温湿度传感器550，上述各温湿度传感器与湿热空气供给装置300电性连接，可控制湿热空气供给装置300相应的湿热气供给量及其它的湿热气相关参数，比如可以但不局限于温度和湿度。
第一温湿度传感器510设于空腔220内，第二温湿度传感器520设于模拟层210外侧表面，第三温湿度传感器530设于第一面料固定板120朝向第二面料固定板130的侧面，第四温湿度传感器540设于第二面料固定板130朝向第一面料固定板120的侧面，第五温湿度传感器550设于安装架110靠近待测面料400的一侧。该方案中，通过第一温湿度传感器510、第二温湿度传感器520、第三温湿度传感器530、第四温湿度传感器540和第五温湿度传感器550各自采集的温湿度参考数据，可以提高温湿度参考数据的可靠性，可以准确校验检测结果的准确率的同时，可以为检测结果的准确度提供可靠性的证据，可以从侧面佐证检测结果的真实性。第二温湿度传感器520可以位于模拟层210外侧表面的最靠近待测面料400的端面，当模拟块200在旋转过程中，待测面料400与模拟层210接触或相挤压时，第二温湿度传感器520会与待测面料400直接接触，第二温湿度传感器520所采集的数据会受到待测面料400温湿度的影响，也即第二温湿度传感器520能够为检测结果提供准确可靠的温湿度参考数据，甚至可以作为检测结果的检测数据之一，从而有效提高检测结果的准确率；当然，在另一些实施例中，第二温湿度传感器520可以位于模拟层210外侧表面的不靠近待测面料400的端面，当模拟块200在旋转过程中，第二温湿度传感器520不会与待测面料400接触，第二温湿度传感器520所采集的数据为模拟层210外侧表面的温湿度数据。
为了便于调控模拟的待测面料400使用环境，在一些实施例中，湿热空气供给装置300包括第一供给装置310、第二供给装置320和第三供给装置330，第一供给装置310通过第一管道311与第一通道141连通，第二供给装置320通过第二管道321与湿热检测腔160的顶侧连通，第三供给装置330通过第三管道331与湿热检测腔160的底侧连通。该方案中，通过第一供给装置310、第二供给装置320和第三供给装置330，可以分别通入不同温湿度的湿热空气，从而调控模拟的待测面料400使用环境，进而能够准确模拟待测面料400使用环境。
在一些实施例中，第一供给装置310、第二供给装置320和第三供给装置330均包括风机301、水箱302和电加热管303，电加热管303设于水箱302内，第一管道311、第二管道321和第三管道331分别与对应的风机301连接，风机301通过第四管道与水箱302的内部上侧连接，以抽取湿热空气。
在一些实施例中，水箱302的内部顶侧设有第六温湿度传感器560。该方案中，通过第六温湿度传感器560检测水箱302内部的湿热空气的温湿度，可以准确控制电加热管303的工作。
在一些实施例中，第一温湿度传感器510、第三温湿度传感器530、第四温湿度传感器540和第六温湿度传感器560均包括温度传感器和湿度传感器，温度传感器配置有温控电路。
在一些实施例中，如图6所示，温控电路包括电阻R1、电阻R2、电阻R3、电阻R4、电阻R5、电阻R6、电阻R7、电阻R8、电阻R9、电容C1、电容C2、电容C3、电容C4、二极管D1、稳压管ZD1、稳压管ZD2、三极管Q1、运放芯片IC、热敏电阻RT和继电器KM；
二极管D1的正极外接电源端Vcc，二极管D1的负极与电阻R9的一端连接，电阻R9的另一端均与电阻R1的一端、热敏电阻RT的一端、电容C1的一端、电容C2的一端、运放芯片IC的引脚8、稳压管ZD2的负极和电容C4的正极连接，电阻R1的另一端均与电阻R2的一端、电容C2的另一端和电阻R5的一端连接，热敏电阻RT的另一端与电阻R4的一端连接，电容C1的另一端均与电阻R6的一端、电阻R4的另一端、电阻R3的一端和电阻R7的一端连接，电阻R5的另一端均与电容C3的一端和运放芯片IC的引脚6连接，电阻R6的另一端均与电容C3的另一端和运放芯片IC的引脚5连接，电阻R7的另一端均与运放芯片IC的引脚7和电阻R8的一端连接，电阻R8的另一端与三极管Q1的基极连接，三极管Q1的集电极均与继电器KM和稳压管ZD1的负极连接，电阻R2的一端、电阻R3的一端、运放芯片IC的引脚4、三极管Q1的发射极、稳压管ZD2的正极、稳压管ZD1的正极和电容C4的负极均接地；
其中，热敏电阻RT为温度传感器在电路中的表示，继电器KM与电加热管303连接，以控制电加热管303的工作；在实际中，继电器KM的开关触点串联在电加热管303的工作电路中，以控制电加热管303的工作电路的通断，即可控制电加热管303的工作；
运放芯片IC为LM2904，其引脚6为反相端，其引脚5为同相端；电源端Vcc可以为12VDC，电阻R1和电阻R2之间的电压为基准电压，电阻R4和电阻R3之间的电压为比较电压；当基准电压大于比较电压时，运放芯片IC的引脚7为低电平；当基准电压小于比较电压时，运放芯片IC的引脚7为高电平；
所述温度传感器为负温度系数热敏电阻或正温度系数热敏电阻；
当所述温度传感器为负温度系数热敏电阻时，电加热管303与继电器KM的常闭触点连接；温度传感器所检测的环境温度升高时，热敏电阻RT的阻值变小，当变化到一定值，比较电压大于基准电压，运放芯片IC的引脚7为高电平，三极管Q1导通，继电器KM的线圈得电，继电器KM的常闭触点断开，电加热管303停止工作；温度传感器所检测的环境温度降低时，热敏电阻RT的阻值变大，当变化到一定值，比较电压小于基准电压，运放芯片IC的引脚7为低电平，三极管Q1截止，继电器KM的线圈失电，继电器KM的常闭触点闭合，电加热管303工作；
当所述温度传感器为正温度系数热敏电阻时，电加热管303与继电器KM的常开触点连接；温度传感器所检测的环境温度升高时，热敏电阻RT的阻值变大，当变化到一定值，比较电压小于基准电压，运放芯片IC的引脚7为低电平，三极管Q1截止，继电器KM的线圈失电，继电器KM的常开触点断开，电加热管303停止工作；温度传感器所检测的环境温度降低时，热敏电阻RT的阻值变小，当变化到一定值，比较电压大于基准电压，运放芯片IC的引脚7为高电平，三极管Q1导通，继电器KM的线圈得电，继电器KM的常开触点闭合，电加热管303工作；
在实际应用中，可以通过多次试验，适当设置各个电子元器件的参数，如待测面料400应用于人体时，人体皮肤温度一般在36.1℃～37℃，以37℃为例；当温度小于37℃时，电加热管303工作；当温度大于37℃时，电加热管303停止工作；从而使得温度传感器所检测的模拟层210外侧表面温度保持在37℃左右，当然可以允许有±1℃～2℃的误差，便于减少试验次数和便于设置各个电子元器件的参数；其余待测面料400的使用环境，或温度传感器所检测的环境温度，根据上述进行相应的参数设置，即可将温度控制在相应的所需范围内，从而精准模拟出待测面料400的使用环境，进而提高检测结果的准确率。
综上，第一温湿度传感器510、第三温湿度传感器530、第四温湿度传感器540和第六温湿度传感器560各自的温控电路的参数设置可以不同，因为各自的检测环境不一样；第一温湿度传感器510和/或第六温湿度传感器560、第一供给装置310和对应的温控电路构成第一温控机构，第三温湿度传感器530和/或第六温湿度传感器560、第二供给装置320和对应的温控电路构成第二温控机构，第四温湿度传感器540和/或第六温湿度传感器560、第三供给装置330和对应的温控电路构成第三温控机构，通过第一温控机构、第二温控机构和第三温控机构相互配合，可以精准模拟出待测面料400的使用环境，进而提高检测结果的准确率；其中，当使用两个热敏电阻RT时，两个热敏电阻RT可以串联接入电路。
综上所述，公开了本发明的多个具体实施例，在不自相矛盾的情况下，各个实施例可以自由组合形成新的实施例，也即属于替换方案的实施例之间可以自由替换，但不能相互组合；不属于替换方案的实施例之间可以相互组合，这些新的实施例也属于本发明的实质性内容。
以上实施例描述了本发明的多个具体实施方式，但是本领域的技术人员应当理解，在不背离本发明原理和实质的前提下，可以对这些实施方式做出多种变更或修改，但这些变更和修改均落入本发明的保护范围内。
