具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。
本申请涉及触控板(或者也称触摸板)。具体地，该触控板可以提供与用户手指交互触摸和按压界面。在按压界面中，触控板可以感应于用户的按压操作，以执行相应的按压反馈或者指示其所在电子设备执行相应功能，该按压界面可以充当“按键”功能。在触摸界面中，触控板可以用于感应用户手指的位置和移动，以执行相应的触摸反馈或者指示其所在电子设备执行相应功能，该触摸界面可以充当“鼠标”功能。
该触控板可以应用于任意一种人机交互设备，例如笔记本电脑、平板电脑、手机、智能可穿戴装置、智能门锁、自动取款机(Automated Teller Machine，ATM)等等，本公开的实施例对此不做限定。
对于触控板的按压界面，在现有技术中，需要利用专用的机械结构件，例如平衡杆等结构件实现按压检测，该触控板的结构较为复杂且厚度较厚，本申请提供一种新的触控板，能够复用触控板中的电路板实现按压检测，触控板整体结构简单、易于装配且厚度较薄。
图1示出了本申请实施例提供的一种触控装置100的示意性爆炸图。图2示出了对应于图1实施例的触控装置100的局部截面示意图。
如图1和图2所示，该触控装置100用于设置在盖板110下方以形成触控板，该触控装置100包括：电路板120、固定支架130和螺纹连接件140。
具体地，电路板120连接于盖板110的下表面，电路板120设置有按压感应元件121。固定支架130设置于电路板120下方，该固定支架130中具有通孔131。螺纹连接件140的一端通过该通孔131连接于电路板120，另一端限位于固定支架130的下表面，该螺纹连接件140用于在该固定支架130与电路板120之间提供间隙。
在手指按压于盖板110的情况下，电路板120带动螺纹连接件140在上述电路板120和固定支架130之间的间隙中沿按压方向移动，以使得电路板120上的按压感应元件121感应手指在盖板110上的按压。
具体地，在本申请实施例中，盖板110可以为触控装置100所在的触控板朝向用户的界面，用于接收用户手指或其它部件在该触控装置100上的按压。该盖板110需具有一定的刚性，其材质例如可以为玻璃，聚碳酸酯(PC)片材，陶瓷片材，麦拉(Mylar)材料等不导电刚性物体，厚度介于0.2mm至1.5mm间。该盖板110用于通过胶层与电路板120粘接，该胶层可以为液态胶或固态胶。
电路板120包括但不限于是印刷电路板(Printed Circuit Board，PCB)，当电路板120上设置有各种元器件的情况下，该电路板120也可以称之为电路板组件(Printed Circuit Board Assembly，PCBA)。该电路板120本身具有一定的刚性和强度，该盖板110和电路板120的整体能够承受用户手指一定压力的按压。该盖板110和电路板120可以通过胶层相互连接，或者，也可以通过机械连接件相互连接。
电路板120上设置有按压感应元件121。在用户手指按压于盖板110时，该盖板110和电路板120可以发生一定程度的变化，例如，位移变化或形变变化，该按压感应元件121可以感应于盖板110和电路板120的变化，以产生按压操作信号。该按压感应元件121可以与电路板120上其它电子元器件电连接，以使得其可以将感应到的按压操作信号通过电路板120反馈给外部设备。
电路板120的下方设置有固定设置的固定支架130，该固定支架130具有一定的刚度和强度以起到良好的固定支撑作用。作为示例而非限定，该固定支架130可以为钢板。该固定支架130中设置有通孔131，螺纹连接件140的一端穿过该通孔131与电路板120相互连接。在静止状态下(即手指未按压于盖板110)，该螺纹连接件140的另一端限位于固定支架130的下表面，且该螺纹连接件140可以在固定支架130与电路板120之间提供一定的间隙。在手指按压于盖板110时，该盖板110和电路板120会沿手指按压方向产生相应形变和相应位移，具体地，该电路板120中的形变区域会沿手指按压方向在电路板120与该固定支架130之间的间隙移动，该电路板120中形变区域的移动会使得该电路板120上的按压感应元件121感应手指在盖板110上的按压操作。
另外，在用户按压于盖板110的情况下，螺纹连接件140限位于固定支架130下表面的一端可以跟随电路板120在按压方向上发生位移变化。即本申请实施例中，螺纹连接件140在静止状态下能够连接电路板120和固定支架130并对电路板120进行限位，在用户按压状态下，该螺纹连接件140能够跟随电路板120发生位移变化。
具体地，该螺纹连接件140可以包括相互配合的螺母和螺丝。为了便于电路板120和固定支架130之间的固定连接，如图2所示，螺母(图2中未示出)可设置于电路板120，该螺母可以嵌入至电路板120的内部或者也可以贴装于电路板120的表面，对应的，螺丝可设置于固定支架130。在该情况下，螺纹连接件140限位于固定支架130下表面的一端可以为螺丝头，其尺寸可以大于通孔131的尺寸，以使得该螺丝头可以限位于通孔 131的下方。或者，在替代实施例中，螺丝也可设置于电路板120，对应的，螺母可设置于固定支架130。
通过本申请实施例的技术方案，可以仅利用电路板120和固定支架130等基本元件实现触控板的压力检测功能。具体地，该电路板120和固定支架130之间通过螺纹连接件140可以实现便于操作、可靠且精度较高的连接。另外，该螺纹连接件140在静止状态下能够固定连接电路板120和固定支架130以对电路板120进行限位并在电路板120和固定支架130之间提供间隙，而在用户按压状态下，该螺纹连接件140能够跟随电路板120在该电路板120和固定支架130之间的间隙发生位移变化，以使得电路板120的按压感应元件121感应手指在盖板110上的按压以实现按压检测功能。该技术方案整体结构简单，厚度较薄，且易于生产和安装，有利于该触控装置100所在的触控板在电子设备中的推广和使用。
在一些相关实施方式中，可能会利用卡扣等结构实现两个物体之间的连接和限位，该卡扣结构不易装配和拆卸，且卡扣和配合件之间难以实现“零配合”连接，造成整体结构尺寸较大。在本申请实施例中，利用螺纹连接件140连接电路板120和固定支架130，该螺纹连接件140便于装配和维修，且螺纹连接可以实现零配合，节省安装所需占用的空间。
图3示出了本申请实施例提供的两种螺纹连接件140与电路板120和固定支架130的局部连接示意图。
如图3中的(a)图所示，螺纹连接件140包括贴片螺母141和螺丝142，该贴片螺母141贴装于电路板120的表面，螺丝142的螺纹结构1421通过固定支架130中的通孔131连接于贴片螺母141，螺丝142的螺丝头1422限位于固定支架130的下表面。
具体地，在该实施例中，贴片螺母141可通过表面贴装技术(Surface Mounted Technology，SMT)焊接于电路板120的表面。该贴片螺母141具有内螺纹，螺丝142的螺纹结构1421具有外螺纹，该贴片螺母141与螺丝142可通过内外螺纹实现可靠的紧固连接。另外，该螺丝的螺丝头1422的尺寸大于固定支架130中的通孔131的尺寸，以使得该螺丝头1422可以限位于该固定支架130的下表面。可选地，该螺丝的螺丝头1422的厚度可小于或等于0.4mm，既可以满足锁附固定支架130的要求，也可以降低其所需占用的厚度空间。
另外，在该实施例中，该贴片螺母141的外径需小于固定支架130中通孔131的直径，以使得该贴片螺母141能够在用户按压的情况下跟随电路板120在该通孔131中移动。
通过该实施例的技术方案，可以利用直接在电路板120的表面设置贴片螺母141，且利用贴片螺母141的高度在电路板120与固定支架130之间提供间隙，该实施方式不仅便于加工组装且整体的连接可靠性以及连接精度较高。
如图3中的(b)图所示，螺纹连接件140包括贴片螺母141和栓打螺丝143，该栓打螺丝143的螺纹结构1431通过固定支架130中的通孔131连接于贴片螺母141，栓打螺丝143的螺丝头1433附接于该固定支架130，该栓打螺丝143的光杆1432位于螺纹结构1431和螺丝头1433之间，用于提供贴片螺母141和固定支架130之间的间隙。
可选地，在本申请实施例中，配合于贴片螺母141的螺丝可以为包括三级结构的栓打螺丝143，或者，在一些相关实施方式中，该栓打螺丝也可以称之为塞打螺丝。其中， 栓打螺丝143中的光杆1432为栓打螺丝143的中间级结构，其连接于螺纹结构1431与螺丝头1433。该光杆可以为表面光滑的柱体结构，其径向尺寸可以大于螺纹结构1431的径向尺寸，因此，该光杆1432可以在轴向上对螺纹结构1431与贴片螺母141之间的连接进行紧固和限位，以进一步提高螺纹结构1431与贴片螺母141之间的连接可靠性。另外，该光杆的表面粗糙度较小，可以避免与其它结构件，例如固定支架130之间产生摩擦阻力，提升该光杆1432所在的栓打螺丝143的移动灵活性。
光杆1432和螺纹结构1431通过固定支架130中的通孔131后，螺纹结构1431连接于电路板120上的贴片螺母141，螺丝头1433限位于固定支架130的下表面，以实现对固定支架130与电路板120之间的连接，且光杆1432提供了贴片螺母141与固定支架130之间的间隙，以使得贴片螺母141在用户按压的情况下能够跟随电路板120在该间隙中移动。
另外，在该实施例中，该光杆1432的外径需小于固定支架130中通孔131的直径，以使得该光杆1432能够在用户按压的情况下跟随电路板120在该通孔131中移动。
通过本申请实施例的技术方案，螺丝设计为栓打螺丝143，该栓打螺丝143一方面也能实现与贴片螺母141的紧固配合，另一方面，光杆1432的设计能够使得该栓打螺丝143能够灵活的在固定支架130的通孔131的移动，提升触控装置100的压力检测性能。
可选地，如图3中(b)所示，固定支架130中的通孔131的直径可以小于贴片螺母141的外径。
通过该实施方式的技术方案，当用户按压于盖板110时，贴片螺母141向下移动，当贴片螺母141被按压至固定支架130时，则不能被继续下压。此时，贴片螺母141可以作为按压方向上的限位件，固定支架130不会与电路板120上的其他器件接触，从而可防止用户按压盖板110时，按压压力过大使得固定支架130对电路板120上的器件造成损伤，影响了触控装置100的整体使用性能。
对于图3中(a)图所示的技术方案，也可以在贴片螺母141或者贴片螺母141的四周额外设置限位件，以防止用户按压盖板110时对固定支架130与电路板120相互接触，对电路板120上的器件造成损伤。
可选地，在一些实施方式中，螺纹连接件140具有与其对应的限位件。可选地，该限位件与螺纹连接件140可以设置于电路板120中相对的两端。
作为示例，图4示出了螺纹连接件140与其对应的限位件1400在电路板120上的示意图。
如图4中的(a)图所示，在静态情况下，螺纹连接件140位于电路板120的第一端，该电路板120的与第一端相对的第二端设置有限位件1400。作为示例，该电路板120的第一端可以为该电路板120在长度方向上的其中一端，相对的，该电路板120的第二端可以为该电路板120在长度方向上的另外一端。当然，该电路板120的第一端和第二端还可以为电路板120在宽度方向上的两端或者电路板120在对角线方向上的两端。
如图4中的(b)图所示，在手指按压于盖板110的第一端情况下，手指向该第一端施加压力F，该盖板110和电路板120的第一端带动螺纹连接件140沿按压方向移动(如图中虚线所示)，该限位件1400用于对电路板120的第二端限位，防止该电路板120的第二端沿按压方向的反方向移动。
可选地，该限位件1400可以为连接于电路板120与固定支架130(图4中未示出) 的连接件。该限位件1400包括但不限于是：胶层、卡扣结构或者其它类型的连接结构。在固定支架130固定设置的情况下，该限位件1400可以保证电路板120的第二端也固定设置，从而对该电路板120的第二端进行限位。可选地，在一些实施方式中，上述限位件1400也可以是螺纹连接件140。在该情况下，固定支架130可以通过至少一对螺纹连接件140连接于电路板120，该至少一对螺纹连接件140中的每对螺纹连接件140相对于电路板120的对称轴对称设置。
具体地，在该实施方式中，该电路板120的表面可以为规则的轴对称图形，例如，该电路板120的表面包括但不限于是矩形，该电路板120可以为矩形电路板。在该情况下，电路板120具有两条对称轴，该至少一对螺纹连接件140中的每对螺纹连接件140可以相对于该两条对称轴中的任意一条对称轴对称设置。
作为示例，图5示出了一对螺纹连接件140(第一螺纹连接件1401和第二螺纹连接件1402)与电路板120和固定支架130的连接示意图。其中，作为示意，该一对螺纹连接件140中每个螺纹连接件可以包括上述栓打螺丝143和贴片螺母141。
如图5中的(a)图所示，在静态情况下，第一螺纹连接件1401和第二螺纹连接件1402中栓打螺丝的螺丝头均附接于固定支架130，该固定支架130与电路板120之间具有一定的间隙。
如图5中的(b)图所示，在手指按压于盖板110中偏向于第二螺纹连接件1402的右侧区域时，手指向该右侧区域施加向下的压力F。盖板110以及电路板120的右侧区域在该压力F的作用下，均向下发生移动，从而带动第二螺纹连接件1402向下移动。与此同时，位于左侧的第一螺纹连接件1401仍然可处于静态，该第一螺纹连接件1401可以防止盖板110以及电路板120的左侧区域向上翘起，保证触控装置100所在的触控板的整体使用可靠性。
类似地，当手指按压于盖板110中偏向于第一螺纹连接件1401的左侧区域时，盖板110以及电路板120的左侧区域带动第一螺纹连接件1401向下移动，位于右侧的第二螺纹连接件1402仍然可处于静态，该第二螺纹连接件1402可以防止盖板110以及电路板120的右侧区域向上翘起。
可选地，如图4和图5所示，为了便于电路板120上的按压感应元件121感应手指的按压，该按压感应元件121可以位于电路板120的中心区域。在该情况下，无论用户的按压位置处于电路板120的边缘区域还是中心区域，该按压感应元件均可以较为明显的感应到手指的按压。
需要说明的是，该电路板120的中心区域可以具有一定范围区域，该中心区域的中心即为电路板120的中心，且该中心区域的面积可以取决于电路板120的整体面积。作为示例而非限定，该中心区域的面积可以为电路板120的整体面积的1/4或者1/16等等。
可选地，在图4和图5所示实施例中，按压感应元件121可以为具有形变能力的弹性结构，且固定支架130上设置有与该弹性结构对应的凸起结构132。当用户按压于盖板110中，该弹性结构能够被凸起结构132挤压产生形变，从而用于检测用户的按压。
通过本申请实施例的技术方案，该触控装置100所在的触控板可以为一种全域按压的触控板，即用户手指可按压于触控板中的任意位置，该触控板均能感应到用户手指的按压，从而能够极大程度的提高用户对该触控板的使用体验。
图6示出了本申请实施例提供的两种电路板120的示意性仰视图。可以理解的是， 在螺纹连接件140包括上文实施例的贴片螺母141的情况下，该图6中所示的螺纹连接件140具体可以为上文实施例中的贴片螺母141。
作为一种示例，如图6中的(a)图所示，电路板120可以为矩形电路板，固定支架130可以通过两对螺纹连接件140连接于电路板120，其中，该两对螺纹连接件140设置于矩形电路板的四角区域。

在手指按压于触控板的盖板110的一侧边缘区域时，该盖板110以及电路板120中的另一侧边缘区域作为易于翘起。因此，在该技术方案中，通过两对螺纹连接件140将电路板120的四角区域连接于固定支架130，可以良好的防止手指按压于盖板110时，盖板110和电路板120的四角区域翘起，可靠保证触控装置100所在的触控板的按压性能。
作为另一种示例，如图6中的(b)图所示，电路板120可以为矩形电路板，固定支架130可以通过三对螺纹连接件140连接于电路板120，其中，该三对螺纹连接件140中的两对螺纹连接件140设置于矩形电路板的四角区域，另一对螺纹连接件140设置于矩形电路板的中心区域。
在该示例的技术方案中，该三对螺纹连接件140同样可以相对于电路板120的对称轴对称设置，与此同时，四个螺纹连接件140设置于矩形电路板的四角区域，另两个螺纹连接件140设置于矩形电路板的中心区域。
在该技术方案中，除了两对螺纹连接件140将电路板120的四角区域连接于固定支架130，可以良好的防止手指按压于盖板110造成盖板110和电路板120的四角区域翘起的问题，还可以进一步的通过一对螺纹连接件140将电路板120的中心区域连接于固定支架130，保证用户手指在该中心区域处的按压性能。
可选地，如图6所示，四个螺纹连接件140分别位于矩形电路板的四角区域。以该螺纹连接件140包括上文实施例中的贴片螺母141为例，在本申请实施例中，参照图6中的(a)图和(b)图所示，在矩形电路板的短边方向上，该贴片螺母141与矩形电路板的边缘的距离为D1，在矩形电路板的长边方向上，该贴片螺母141与矩形电路板的边缘的距离为D2。其中，该D1和/或D2可以大于或等于10mm，以防止该贴片螺母141距离电路板120的边缘太近使得外部环境对该贴片螺母141以及栓打螺丝143造成影响从而影响触控装置100的使用可靠性。另外，该D2可以小于或等于矩形电路板长边尺寸的1/4，和/或，D1可以小于或等于矩形电路板短边尺寸的1/4，以使得该贴片螺母141以及栓打螺丝143靠近于矩形电路板的边缘设置。
进一步参照图6中的(b)图所示，在触控装置100包括三对栓打螺丝143和贴片螺母141的情况下，该位于电路板120的中心区域的贴片螺母141与电路板120的中心的距离为D3，该D3可以在10mm左右，例如，该D3可以在10mm±5mm的范围内，以使得贴片螺母141与栓打螺丝143靠近于电路板120的中心设置。
可选地，在一些实施方式中，上述触控装置100还包括：第一弹性件，设置于电路板120与固定支架130之间，该第一弹性件在电路板120与固定支架130之间提供弹性支撑。

结合图9中(a)图和(b)图所示，该凸包1512可以为空心凸起结构。一方面，该空心凸起结构能够降低条状硅胶垫1503的整体重量，另一方面，该空心凸起结构也可以改善用户手指对于该触控装置100所在的触控板的按压体验。
如图9中的(c)图所示，为了增强该条状硅胶垫1503在按压方向的稳定性，防止该多个条状硅胶垫1503在水平方向上产生位移，该条状硅胶垫1503可以通过胶层连接于电路板120以及固定支架130。
具体地，该条状硅胶垫1503的凸包1512的上表面设置有第一胶层1513，且该条状硅胶垫1503的下表面设置有第二胶层1514，该条状硅胶垫1503通过该第一胶层1513和第二胶层1514连接于电路板120以及固定支架130。

图12示出了本申请实施例提供的第二硅胶垫1502的示意性立体图。其中，图12中的(b)图为(a)图上下翻转后的示意图，图12中的(c)图为在(a)图的基础上增加胶层以及补强片的示意图。

可选地，该凸包1521可以为空心凸起结构。一方面，该空心凸起结构能够降低第二硅胶垫1502的整体质量，另一方面，该空心凸起结构也可以改善用户手指的按压体验。
如图12中的(c)图所示，触控装置100还可包括：补强片1504，该第二硅胶垫1502的第一面设置有凸包1521，该补强片1504设置于该第二硅胶垫1502的与第一面相对的第二面，该第二硅胶垫1502通过该补强片1504和凸包1521分别连接于固定支架130和电路板120。

第一弹性件除了可以为如图7至图12中所示的硅胶垫以外，还可以为弹片。
图13示出了本申请实施例提供的另一触控装置100的示意性爆炸结构图。
如图13所示，该第一弹性件即为弹片1505，该弹片1505贴装于电路板120的表面。
在螺纹连接件140包括贴片螺母141和栓打螺丝143的情况下，图14示出了该弹片1505与电路板120和固定支架130的连接示意图。
如图13和图14所示，该弹片1505可以为悬臂梁结构，其固定端连接于电路板120，其自由端附接于固定支架130。在静止状态下，该弹片1505可以在电路板120与固定支架130之间起到一定支撑作用。在用户手指按压于盖板110的情况下，该弹片1505的自 由端受到固定支架130的反作用力向上弹起，用户在该触控装置100所在的触控板按压时，用户手指能够具有较好的按压感受。
可选地，该弹片1505可以设置于螺纹连接件140靠近于电路板120的中心的一侧，且与螺纹连接件140相邻设置。可选地，该弹片1505可以通过SMT工艺贴装于电路板120的表面。
通过本申请实施例的技术方案，将第一弹性件设计为弹片1505，可以直接在电路板120的制造阶段将弹片1505贴装于电路板120，避免了后续还需通过额外的工序在电路板120与固定支架130之间设置弹性件，从而提高触控装置100的制造效率。
可选地，在一些实施方式，如图13和图14所示，弹片1505可以与螺纹连接件140相邻设置。在螺纹连接件140的数量为多个的情况下，该弹片1505可以与螺纹连接件140一一对应。例如，在图13所示实施例中，四个弹片1505可以一一对应的与四个螺纹连接件140相邻设置。
通过该实施方式的技术方案，弹片1505可以在静止状态下，对螺纹连接件140的周围空间起到一定的支撑作用，在用户按压的状态下，该弹片1505可以提高用户的按压手感，从而提升用户对触控装置100所在的触控板的使用体验。
可选地，在图13和图14所示实施例中，多个弹片1505除了与螺纹连接件140相邻设置的技术方案以外，该多个弹片1505还可以分布设置于电路板120的对称轴的两侧。例如，该多个弹片1505分布设置于电路板120中平行于短边方向的对称轴的两侧。
或者，在其它实施例中，多个弹片1505可以仅分布设置于电路板120的对称轴的两侧，而不与螺纹连接件140相邻设置，例如，触控装置100可以包括两个弹片1505，该两个弹片1505可分别设置于电路板120中平行于短边方向的对称轴的两侧区域。
通过该实施方式的技术方案，弹片1505可以均匀的在电路板120中分布设置，便于在触控装置100所在的触控板的全局提供弹性支撑且提升用户的按压体验。
在上文图7至图14所示实施例中，电路板120与固定支架130之间设置有第一弹性件，以在电路板120与固定支架130之间提供弹性支撑。可选地，在其它实施例中，触控装置100还包括：第二弹性件，其可在螺纹连接件140与固定支架130之间提供弹性缓冲。
作为示例，在图10所示实施例的基础上，图15示出了本申请实施例提供的另一触控装置100的示意性爆炸结构图。
如图15所示，该触控装置100还包括：第二弹性件160，设置于螺纹连接件140与固定支架130之间，且围绕于螺纹连接件140的四周，该第二弹性件160在螺纹连接件140与固定支架130之间提供弹性缓冲。
在螺纹连接件140包括贴片螺母141和栓打螺丝143的情况下，图16示出了该第二弹性件160与固定支架130的连接示意图。
可选地，为了便于第二弹性件160在螺纹连接件140四周的装配，该第二弹性件160可以为硅胶垫。作为示例，如图16所示，在螺纹连接件140包括栓打螺丝143的情况下，该硅胶垫可以套接于该栓打螺丝143的光杆1432，且附接于该栓打螺丝143的螺丝头1433。该栓打螺丝143通过固定支架130中的通孔131连接于电路板120上的贴片螺母141后，该硅胶垫可以抵接于固定支架130的下表面以及螺丝头1433的上表面，以在该固定支架130与螺丝头1433之间提供弹性缓冲。
通过本申请实施例的技术方案，在螺纹连接件140与固定支架130之间设置第二弹性件160。在用户手指在撤销对盖板110的按压的情况下，螺纹连接件140会根据电路板120向上弹起，该第二弹性件160可以防止螺纹连接件140直接接触于固定支架130，使得二者之间发生碰撞而产生声音影响用户的使用体验。
需要说明的是，图15和图16仅作为一种示意说明了本申请实施例中包括第二弹性件160的触控装置100的结构，在其它替代实施例中，触控装置100也可以仅包括第二弹性件160而不包括第一弹性件，或者，触控装置100中的第一弹性件还可以为图7至图14中任意一种实施方式的弹性件。
在上文申请实施例中，触控装置100所在的触控板通过盖板110和电路板120承受用户的按压，为了满足用户按压需求，该盖板110和电路板120需满足一定的刚性和强度，因此，盖板110可能会选用刚度较高的玻璃材质，和/或，电路板120会具有较大的厚度提升其抗压强度。
鉴于此，图17示出了本申请实施例提供的另一触控装置100的示意性爆炸结构图。
如图17所示，在本申请实施例中，触控装置100还可以包括：补强板170，连接于电路板120的下表面，以对电路板120进行补强。
可选地，该补强板170可以为具有较高强度的金属板，例如钢板等等。该补强板170的强度高于电路板120的强度，因此，在相同厚度下，补强板170和电路板120的组合的强度会高于单独的电路板120的强度。
另外，该补强板170的刚性也强于电路板120的刚性。在电路板120的制造过程中，其易于出现翘曲等问题，在补强板170连接于电路板120的下表面后，该补强板170能够改善电路板120的翘曲问题，提升该电路板120的平整度。
通过在电路板120的下表面连接补强板170，可以提高该电路板120的强度和平整度。在提高电路板120的强度的情况下，可以提高触控装置100的整体抗压能力，且可以使得盖板110采用玻璃以外的其它材料，例如Mylar材料等，不仅能够降低盖板110及其所在的触控板的质量，还能降低制造成本。在提高电路板120的平整度的情况下，也可以便于用户对该盖板110和电路板120整体的按压，提升触控装置100所在的触控板的按压检测性能。
可选地，在一些实施方式中，电路板120的厚度为0.5mm左右，与其连接的补强板170的厚度为0.25mm左右，该电路板120和补强板170的厚度设计可以同时满足小的厚度以及高的强度要求，从而节省触控装置100的厚度空间且保证触控装置100的按压需求。
可选地，如图17所示，补强板170中形成有通孔，该通孔可用于容置电路板120中电子元器件。例如，通孔可用于容置贴装于电路板120上的贴片螺母141、按压感应元件121等多种元器件。该补强板170既能对电路板120起到补强作用，也不会影响电路板120上各种电子元器件的设置。
可选地，在本申请实施例中，该触控装置100可以进一步包括上文图7至图14中任意一种实施例提供的第一弹性件，该第一弹性件可以设置于补强板170和固定支架130之间，该第一弹性件在该补强板170和固定支架130之间提供弹性支撑。

如图17和图18中的(a)图所示，第一弹性件可以为上述第二硅胶垫1502。该第二硅胶垫1502可与螺纹连接件140相邻设置，且该第二硅胶垫1502可以抵接于补强板170的下表面以及固定支架130的上表面。
如图18中的(b)图所示，第一弹性件可以为弹片1505，该弹片1505贴装于电路板120的表面，且可以容置于补强板170的通孔中。
或者，在其它实施例中，第一弹性件还可以为上述第一硅胶垫1501。具体地，该第一弹性件的相关技术方案可以参见上文图7至图14所示实施例的具体描述，此处不再赘述。
在第一弹性件为弹片1505的情况下，其除了可以如图18中的(b)图所示，贴装于电路板120的表面以外，还可以集成于补强板170中。
图19示出了本申请实施例提供的一种集成有弹片1505的补强板170的示意性结构图。
如图19所示，在本申请实施例中，补强板170中可集成设置有多个弹片1505，该弹片1505在补强板170中的位置设计可以参见上文图13和图14所示实施例中弹片1505在电路板120中的位置设计。
作为示例而非限定，该弹片1505可以通过冲压工艺在该补强板170中制备形成，或者，在其它实施方式中，该弹片1505还可以通过其它一体成型工艺形成于补强板170中，本申请实施例对其不做具体限定。
通过本申请实施例的技术方案，补强板170和弹片1505可以集成为一体，而不需要额外利用其它材料制备弹片，因而可以节省触控装置100的整体制造成本。
图20示出了本申请实施例提供的另一触控装置100的示意性爆炸结构图。
如图20所示，在本申请实施例中，上述电路板120上的按压感应元件121可以包括：行程开关122，固定支架130上设置有配合于该行程开关122的凸起结构132。
在用户手指按压于盖板110的情况下，电路板120上的行程开关122沿按压方向移动并接触于凸起结构132，以使得该行程开关122导通以产生响应于手指按压的按压感应信号。
作为一种可能的实施方式，图21示出了与图20相对应的行程开关122和凸起结构132的示意截面图。
可选地，如图21所示，上述行程开关122包括凸起于电路板120的挠性结构1221以及设置于电路板120表面的触点(图21中未示出)。在用户手指按压于盖板110的情况下，该挠性结构1221沿按压方向移动并接触于固定支架130中的凸起结构132以使得挠性结构1221形变，形变后的挠性结构1221接触于电路板120的触点以使得该行程开关122导通。
通过本申请实施例的技术方案，利用行程开关122以及与其相配合的凸起结构132，能够较为有效且敏感的感应用户在触控装置100所在的触控板上的按压，该实施方式可靠性较高。
作为示例，在图21所示实施例中，该挠性结构1221可以为锅仔片，该行程开关122可以理解为dome键。
可选地，该锅仔片的径向尺寸可以大于固定支架130上的凸起结构132的径向尺寸，以使得该锅仔片被凸起结构132接触并挤压时，可以具有一定的形变空间，从而保证锅 仔片的使用性能。
或者，在一些替代实施例中，该行程开关122除了可以为图21中所示的dome键以外，还可以为switch开关，本申请实施例对该行程开关122的具体实现方式不做限定。
