图1示例了本公开实施方式的一种健身垫的结构示意图，图2示例了本公开实施方式的一种压变感应层的***结构示意图。如图1和图2所示，该健身垫包括：健身垫本体1和压变感应层2，健身垫本体1具有容置腔(图中未示出)，压变感应层2位于容置腔内。压变感应层2包括导电层21，以及位于导电层21两侧且与导电层21至少部分接触的第一压变层22、第二压变层23，第一压变层22包括至少一个第一压变单元221，第一压变单元221、第二压变层23在导电层21上的正投影至少部分重合，第一压变单元221、第二压变层23用于与外部检测电路电连接；第一压变单元221、第二压变层23中的至少一者具有压变区222(图中未示出)，压变区222与导电层21之间具有间隙，压变区222能够在外力作用下产生弹性形变且至少部分与导电层21接触。
本公开实施方式中，将第一压变单元221、第二压变层23与外部检测电路电连接，用户使用健身垫10时，健身垫10上的受力位置会因为外力作用而促使第一压变单元221、第二压变层23中具有压变区222的一者产生弹性形变，增大第一压变单元221、第二压变层23与导电层21之间的接触面积，而在接触面积变大的情况下第一压变单元221与第二压变层23之间的导电电阻变小，如此外部检测电路检测的电路参数发生变化，从而便于电路参数的变化，确定用户在健身垫10上的受力位置。
其中，导电层21主要用于导通第一压变单元221和第二压变层23，如此，导电层21只要具有导电功能即可。示例地，导电层21的材料为导电碳膜，本公开实施方式对此不做限定。
其中，第一压变单元221、第二压变层23所使用的材料具有良好的 变形及自我恢复能力，以便在施加有外力时能够产生弹性形变，且在外力去除后能够恢复至原状。压变区222是指第一压变单元221、第二压变层23朝向导电层21的表面上凹陷的区域，如此第一压变单元221、第二压变层23在外力作用下向靠近导电层21的一侧发生形变，以使得第一压变单元221的压变区222的至少部分与导电层21接触，从而增大第一压变单元221与导电层21的接触面积，相应的增大第二压变层23与导电层21的接触面积。
如图3和图4所示，压变区222可以是指微观层面上所具有的凹陷结构对应的区域，也即是构成第一压变单元221、第二压变层23的材料本身具有压变区222，示例地，第一压变单元221、第二压变层23的材料为铜箔或铝箔等，铜箔、铝箔的表面具有凹凸不平的凹陷结构，如图5所示，压变区222在外力F的作用下发生朝向导电层21的弹性形变。当然，如图6所示，压变区222也可以是宏观层面上所具有的凹陷结构对应的区域，即第一压变单元221、第二压变层23通过一定的加工工艺制作后具有压变区222，示例地，第一压变单元221、第二压变层23朝向导电层21的表面呈波纹状的凹陷结构，图7所示，压变区222在外力F的作用下发生朝向导电层21的弹性形变。
本公开实施方式中，第一压变单元221、第二压变层23固定在导电层21上，当然也可以固定在健身垫本体1上。
以第一压变单元221具有压变区222为例，当第一压变单元221固定在导电层21上时，为了避免粘接剂填充第一压变单元221上的压变区222，以阻碍压变区222在外力作用下的变形，可以在第一压变单元221的边缘设置一圈平面接触区，以在平面接触区涂敷粘接剂，进而通过粘接剂将第一压变单元221固定在导电层21上。
本公开实施方式中，多个第一压变单元221呈阵列分布，如此可实现健身垫10上较大区域的检测，且还能够通过设置第一压变单元221的分布密度，来提高受力位置检测的准确性。当然，多个第一压变单元221也可以根据需求进行分布，比如以健身垫10为跳舞毯为例，如图8所示，健身垫10具有五个压变感应区24，此时可在这五个压变感应区 24分别设置第一压变单元221，从而在实现位置检测的同时节省了第一压变单元221的用料。
在一些实施方式中，如图9所示，第一压变单元221为条状结构，第一压变单元221沿行方向延伸，且多个第一压变单元221沿列方向分布，也即是多个第一压变单元221分布为1*N的阵列(N为第一压变单元221的个数)。
由于第一压变单元221在延伸方向具有一定长度，无法单独通过第一压变单元221确定健身垫10上的受力位置，如此，如图9所示，第二压变层23包括多个第二压变单元231，第二压变单元231沿列方向延伸，且多个第二压变单元231沿行方向分布，任一第一压变单元221与多个第二压变单元231在导电层21上的正投影均存在重合区域。
在检测多个第一压变单元221中的任一第一压变单元221和多个第二压变单元231中的任一第二压变单元231之间的电流时，由于该任一第一压变单元221与该任一第二压变单元231在导电层21的厚度方向具有重叠区域，若检测的电流相对变大，则表示该重叠区域为健身垫10上的受力位置。
其中，第二压变单元231除了沿列方向延伸外，也可以是第二压变单元231沿与行方向相交的任一方向延伸，只要任一第一压变单元221与多个第二压变单元231在导电层21的厚度方向上的正投影存在重合区域即可，本公开实施方式对此不做限定。
其中，第一压变单元221具有压变区222，此时第一压变单元221与导电层21部分接触，第二压变单元231与导电层21整面接触；或者第二压变单元231具有压变区222，此时第一压变单元221与导电层21整面接触，第二压变单元231与导电层21部分接触；或者第一压变单元221、第二压变单元231均具有压变区222，此时第一压变单元221、第二压变层23与导电层21均为部分接触，本公开实施方式对此不做限定。
当第一压变单元221、第二压变单元231均具有压变区222时，在施加外力时，第一压变单元221、第二压变单元231与导电层21的接触面积的变化量最大，从而能够最大程度的减小第一压变单元221与第二压变单元231之间的导通电阻，以促使第一压变单元221与第二压变单 元231之间的导通电流变化最为明显。
在另一些实施方式中，第一压变单元221为圆形或矩形结构，当然第一压变单元221也可以为其他异形结构，本公开实施方式对此不做限定。示例地，如图10所示，第一压变单元221包括具有一定长度的第一主干2211，沿与第一主干2211的长度方向垂直的方向延伸的多个第一枝干2212。
其中，第一压变单元221的位置能够代表健身垫10上的受力位置，如此在用户对健身垫10对施加外力时，可确定第一压变单元221的位置，再将第一压变单元221的位置确定为健身垫10上的受力位置。
其中，第二压变层23为一整片结构，或者第二压变层23包括与多个第一压变单元221一一对应的多个第二压变单元231，对应的第一压变单元221和第二压变单元231在导电层21上的正投影至少部分重合。如此，多个第一压变单元221、多个第二压变单元231与外接电路电连接时，相对应的第一压变单元221和第二压变单元231连接在外接电路的两端，以能够形成单独的电回路。
其中，第二压变单元231的形状与第一压变单元221的形状相同或相似，本公开实施方式对此不做限定。示例地，如图10所示，第二压变单元231具有一定长度的第二主干2311，沿与第二主干2311的长度方向垂直的方向延伸的多个第二枝干2312。此时第二压变单元231与上述所述的具有第一主干2211、第一枝干2212的第一压变单元221能够拼成矩形结构，如此，可在增大检测区域的同时减少第一压变单元221、第二压变单元231的用料。
对于包括第一压变单元221、第二压变单元231的情况，第一压变单元221具有压变区222，此时第一压变单元221与导电层21部分接触，第二压变单元231与导电层21整面接触；或者第二压变单元231具有压变区222，此时第一压变单元221与导电层21整面接触，第二压变单元231与导电层21部分接触；或者第一压变单元221、第二压变单元231均具有压变区222，此时第一压变单元221、第二压变层23与导电层21均为部分接触，本公开实施方式对此不做限定。
当第一压变单元221、第二压变单元231均具有压变区222时，在 施加外力时，第一压变单元221、第二压变单元231与导电层21的接触面积的变化量最大，从而能够最大程度的减小第一压变单元221与第二压变单元231之间的导通电阻，以促使第一压变单元221与第二压变单元231之间的导通电流变化最为明显。
本公开实施方式中，如图1所示，健身垫本体1包括上垫层11和下垫层12，上垫层11的边缘与下垫层12的边缘密封连接，以在上垫层11与下垫层12之间形成密封腔。
其中，上垫层11的边缘与下垫层12的边缘通过绝缘胶粘接，当然，上垫层11的边缘与下垫层12的边缘也可以通过其他方式密封连接，比如通过编织、缝纫方式密封连接。
压变感应层2位于上垫层11和下垫层12之间，结合上述所述的第一压变单元221、第二压变层23的固定方式，此时第一压变层22与上垫层11固定连接，第二压变层23与下垫层12固定连接。如此即可避免在第一压变层22、第二压变层23与导电层21之间设置粘接剂，导致粘接剂阻碍压变区222在外力作用下发生弹性形变的情况，从而提高了健身垫10定位的准确性。
在一些实施方式中，健身垫10还包括绝缘层，压变感应层2与上垫层11、下垫层12之间均具有绝缘层。如此，通过绝缘层的设置实现健身垫10的绝缘性能，以避免用户在使用健身垫10时因漏电而导致的用户触电情况的发生。当然，也可以是上垫层11、下垫层12均采用绝缘材料支撑，以实现健身垫10的绝缘性能，本公开实施方式对此不做限定。
在一些实施方式中，健身垫10还包括防水层，防水层位于第二压变层23与下垫层12之间。此时，第二压变层23固定在防水层，防水层固定在下垫层12上。如此，通过防水层的设置，可以避免地面上的水渍浸入健身垫10，缩短健身垫10的使用寿命，以及避免水渍填充第二压变层23上的压变区222，使得第二压变层23与导电层21之间形成短路，降低健身垫10定位精度的问题。
另外，第一压变层22与上垫层11之间也设置有防水层，如此通过防水层的设置，即可避免滴落在健身垫10上的水渍浸入，缩短健身垫 10的使用寿命，以及填充第一压变层22上的压变区222，使得第一压变层22与导电层21之间形成短路，降低健身垫10定位精度的问题。
图11示例了本公开实施方式提供的一种健身***的结构示意图。如图11所示，该健身***包括信号处理分析电路20(外部检测电路)、终端设备30和上述实施方式的健身垫10；多个第一压变单元221、第二压变层23分别与信号处理分析电路20电连接，信号处理分析电路20用于在用户使用健身垫10时检测电路参数的变化；信号处理分析电路20与终端设备30电连接，终端设备30用于根据电路参数确定健身垫10上的受力位置并进行显示。
结合上述实施方式所述的有益效果可知，本公开实施方式中，用户在使用健身垫10健身时，信号处理分析电路20可检测自身的电路参数是否发生变化(第一压变单元221与第二压变层23之间的导通电阻变化时信号处理分析电路20的电路参数同步发生变化)，进而在终端设备30接收到电路参数时根据该电路参数确定健身垫10上的受力位置，并进行显示，同时终端设备30还可以显示相对应的参考位置，以便于用户可根据参考位置与受力位置的位置比对进行调整，保证用户健身时的高效性，避免因受力位置不准确而降低健身效果或娱乐性。
其中，信号处理分析电路20包括串联的电流计，如此可通过电流计检测电流的变化(也即是电路参数为电流)；或者信号处理线路20包括串联的检测电阻和并联在检测电阻上的电压检测电路，在第一压变单元221与第二压变层23之间的导通电阻变小时，检测电阻上的分压会变大，如此可通过电压检测电路检测电压的变化(也即是电路参数为电压)。
本公开实施方式中，压变感应层2的第一压变层22、第二压变层23与信号处理分析电路20(外部检测电路)电连接，信号处理分析电路20还包括控制器、与多个第一压变单元221一一对应的多个第一控制开关，与多个第一压变单元221一一对应的多个输入端口，控制器与多个第一控制开关电连接，多个输入端口与多个第一压变单元221一一对应电连接，控制器用于按照一定的频率控制多个第一控制开关依次逐个导通。
对于上述所述的第二压变层23为整片结构的情况，信号处理分析电 路20具有一个输出端口，输出端口与第二压变层23电连接。如此在控制器控制多个第一控制开关依次逐个导通时，能够依次逐个检测每个第一压电单元与第二压变层23导通时电路参数的变化，进而将检测的电路参数发送至终端设备30。
对于上述所述的第二压变层23包括多个第二压变单元231，且第一压变单元221、第二压变单元231均为条状结构的情况，信号处理分析电路20具有与多个第二压变单元231一一对应的多个第二控制开关，与多个第二压变单元231一一对应的多个输出端口，控制器与多个第二控制开关电连接，多个输出端口与多个第二压变单元231一一对应电连接，控制器用于在任一第一控制开关导通时按照一定的频率控制多个第二控制开关依次逐个导通。如此在控制器控制多个第一控制开关、多个第二控制开关依次逐个导通时，能够依次逐个检测多个第一压电单元与多个第二压变层23形成的多个重叠区域导通时电路参数的变化，进而将检测的电路参数发送至终端设备30。
对于上述所述的第二压变层23包括多个第二压变单元231，且第一压变单元221、第二压变单元231一一对应的情况，信号处理分析电路20具有与多个输入端口一一对应的多个输出端口，相对应的第一压变单元221、第二压变单元231与相对应的输入端口、输出端口对应电连接，以在相对应的第一压变单元221、第二压变单元231之间能够形成单独的电回路。如此在控制器控制多个第一控制开关依次逐个导通时，能够依次逐个检测多个回路导通时电路参数的变化，进而将检测的电路参数发送至终端设备30。
