具体实施方式
为了解决上述问题，本申请实施例提供一种压力检测模组及电子设备，下面结合本申请实施例附图进一步说明本申请实施例具体实现。
本申请实施例提供一种压力检测模组，如图1所示，图1为本申请实施例一提供的一种压力检测模组的结构图。压力检测模组10设置于电子设备的外壳20内表面与支架30之间，该压力检测模组10包括：第一电极101、第二电极102以及控制器(图中未示出)。
第一电极101固定在外壳20的力输入区域201的内表面，第二电极102固定于支架30上，且第二电极102与第一电极101相对设置。
外壳20的力输入区域201根据接收到的外界压力，带动第一电极101向第二电极102的方向移动。
控制器根据第一电极101以及第二电极102之间的电容变化确定对外界压力的压力检测结果。
具体地，控制器可以采用单独设置的控制芯片或者采用电子设备的控制芯片实现，控制器可以设置于电子设备的外壳20内表面与支架30之间的任意位置，本申请实施例对此并不限定。
具体地，外壳20的力输入区域201为任意形状的区域，力输入区域201可以采用任意标识以指示用户可在此区域施加压力。
本申请实施例的第一电极与第二电极仅需要分别安装至外壳力输入区域的内表面与支架上即可实现压力检测，所占用的电子设备内部空间小，且安装简便。
在本申请实施例一具体实现中，参见图2，压力检测模组10还包括：第二补强板103，第二电极102通过第二补强板103黏附固定于支架30上。
本申请实施例通过在第二电极与支架之间设置第二补强板，从而令第二电极更加紧密贴附于支架上，第二补强板的支撑作用也令第二电极具有更佳的平整度。
为了令第二补强板103实现更佳的贴附与支撑作用，第二补强板103覆盖第二电极102与第二补强板103的接触表面。
具体地，可以采用双面胶的方式令第二补强板103黏附固定于支架30上，以更加简便且低成本地实现第二补强板103的安装。
为了实现更佳的黏附效果，第二补强板103与支架30的接触表面均黏附双面胶。
具体地，第二补强板103可以为钢片。
具体地，第二电极102与第二补强板103之间可以采用涂覆导电胶的方式实现黏附固定，以实现第二电极102简便地固定至第二补强板103上。
在本申请实施例另一具体实现中，参见图3，压力检测模组10还包括：第一补强板104，第一电极101通过第一补强板104黏附固定于外壳20的力输入区域201的内表面。
本申请实施例通过在第一电极与外壳的力输入区域的内表面之间设置第一补强板，从而令第一电极更加紧密、稳固地贴附于外壳的力输入区域的内表面上，第一补强板的支撑作用也令第一电极具有更佳的平整度。
为了令第一补强板104实现更佳的贴附与支撑作用，第一补强板104覆盖第一电极101与第一补强板104的接触表面。
具体地，可以采用双面胶的方式令第一电极101黏附固定于第一补强板104上，以更加简便地实现第一电极101的安装。
为了实现更佳的黏附效果，第一补强板104与第一电极101的接触表面均黏附双面胶。
具体地，第一补强板104可以为钢片。
具体地，第一补强板104可以采用涂覆导电胶的方式实现黏附固定于外壳20的力输入区域201的内表面，以实现第一补强板104简便地固定至外壳20的力输入区域201的内表面。
在本申请实施例再一具体实现中，参见图4a，第一补强板104的长度大于第二补强板103的长度，且第一补强板104在长度方向的两端中至少一端具有一弹性限位部件105，弹性限位部件105的第一端限位于支架30上，弹性限位部件105的第二端固定于第一补强板104，弹性限位部件105的第一端与第二端之间具有间隙。
具体地，长度方向是指沿支架30的长度的方向。值得说明的是，第一补强板通常与支架平行，所以所述长度方向也可以指第一补强板的长度方向。
因此，本申请实施例通过弹性限位部件在施加在外壳的力输入区域的外界压力解除后，提供第一电极远离第二电极所需的回弹力。从而，能够令第一电极远离第二电极以更好的恢复到第一电极未受力时候的位置，进而使压力检测模组能实现准确的压力检测。弹性限位部件通过其第一端限位于支架上，弹性限位部件的第二端固定在第一补强板上，弹性限位部件的第一端与第二端之间的间隙因传导获得的外界压力而变小，当外界压力解除后，第一端与第二端之间的间隙恢复所产生的回弹力带动第一补强板上固定的第一电极朝向远离第二电极的方向移动。本申请实施例弹性限位部件的第一端与第二端仅需要分别固定于支架和第一补强板，其安装简便，且占用电子设备内部空间小。
具体地，为便于实现更佳的回弹效果，参见图4b，弹性限位部件105为U型或者C型，弹性限位部件的第一端以及第二端分别为U型或者C型的两个侧壁。
为了提供更佳的回弹效果，第一补强板104的至少一端部朝第二补强板103所在方向斜向延伸构成连接弹性限位部件105的弹性臂104a。
具体地，所述支架30还包括至少一用于容纳所述弹性限位部件105的容纳腔301及用于卡接所述弹性限位部件105，以避免所述弹性限位部件105沿所述长度方向运动的卡接凸起部302。
参见图4c，弹性限位部件105的第一端通过卡接凹槽1051卡接固定于支架上的卡接凸起部302上，卡接凸起部302与卡接凹槽1051啮合，以避免弹性限位部件105沿所述长度方向运动。
因此，弹性限位部件通过卡接凹槽与支架上的卡接凸起部将弹性限位部件的第一端固定于支架上，避免了固定于弹性限位部件的第一补强板带动第一电极沿长度方向运动，能够保证第一补强板带动第一电极仅沿靠近或者远离第二电极的方向运动，能够更佳地实现压力检测的效果。
具体地，为便于生产制作与安装，弹性限位部件105与第一补强板104一体成型。
具体地，参见图4a，弹性限位部件105可以安装在第一补强板104平行于第一电极101方向的两端。参见图4d，弹性限位部件105也可以安装在第一补强板104平行于第一电极101方向的一端，仅安装在第一补强板104平行于第一电极101方向的一端能够更进一步减小压力检测模组的长度，从而减少占据电子设备的内部空间。
为了令第一补强板更佳紧密地与外壳接触，第一补强板104与外壳20接触的表面具有至少一凸点1041，第一补强板104通过凸点1041与外壳20紧密接触。因此，本申请实施例能够更佳地将外壳20的力输入区域201所接受的外界压力传导至第一补强板104。
在本申请实施例再一具体实现中，参见图5，第一电极101与第二电极102之间具有至少一弹性间隔部件106，弹性间隔部件106的一端固定于第一电极101，弹性间隔部件106的另一端固定于第二电极102。
因此，当施加在外壳的力输入区域的外界压力解除后，本申请实施例通过弹性间隔部件来提供第一电极远离第二电极所需的回弹力。弹性间隔部件接受第一电极传导的外界压力后被压缩。当外界压力解除后，弹性间隔部件所产生的回弹力带动第一电极朝向远离第二电极的方向移动。本申请实施例弹性间隔部件安装简便，且占用电子设备内部空间小。
具体地，为了实现更佳的回弹力，弹性间隔部件106为泡棉或者弹片，且令压力检测模组的结构简单、成本较低。
示例性地，本申请实施例采用两个弹性间隔部件106，令两个弹性间隔部件106提供更加平衡的回弹力。
在本申请实施例再一具体实现中，第一电极101与第二电极102相对设置的面遮挡住第二电极102。从而避免外界环境与第二电极之间产生环境电容，从而造成外界干扰影响压力检测模组的检测结果的准确性和产品一致性。
在本申请实施例再一具体实现中，为了实现更佳简便的安装，第二电极 102黏附固定于支架30上。
本申请实施例无需增加第二补强板，可以仅将第二电极黏附固定于支架上即可。
具体地，可以采用双面胶的方式令第二电极102黏附固定于支架30上，以更加简便地实现第二电极102的安装。
为了实现更佳的黏附效果，第二电极102与支架30的接触表面均黏附双面胶。
本申请实施例提供一种电子设备，如图6所示，图6为本申请实施例电子设备的局部结构图。电子设备的外壳内部具有上述实施例任一具体实现中的压力检测模组10。
具体地，参见图7，电子设备为耳机7，压力检测模组10设置在耳机杆部的外壳内部。
如果电子设备的外壳内部设置一组压力检测模组，则可以节约布置压力检测模组所占用的外壳内部空间，组装压力检测模组的步骤更少，工艺则更加简单。
参见图8a以及图8b，压力检测模组10为两组，且两组压力检测模组10对称设置在支架30的两侧。图8a为弹性限位部件105可以安装在第一补强板104平行于第一电极101方向的两端。参见图8b，弹性限位部件105也可以安装在第一补强板104平行于第一电极101方向的一端，仅安装在第一补强板104平行于第一电极101方向的一端能够更进一步减小压力检测模组的长度，从而更小的电子设备内部空间。
如果电子设备的外壳内部设置两组压力检测模组，则能够提供更加准确的压力感测结果，用户也可以选择在外壳的不同力输入区域施加外力，令用户的使用更加方便。
具体地，为了便于制造与安装，两组压力检测模组分别与支架为一体结构。将两组压力检测模组与支架形成的整体直接塞进电子设备外壳，可更适用与圆通状外壳的安装，无需对外壳进行切割即可完成压力检测模组的安装，既可以简化电子设备的制作工艺和成本，也可以提高压力检测模组的产品良率。
还需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、商品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种 过程、方法、商品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个”限定的要素，并不排除在包括要素的过程、方法、商品或者设备中还存在另外的相同要素。
本说明书中的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。尤其，对于系统实施例而言，由于其基本相似于方法实施例，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
以上仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
