同时，压力传感器50设置于所述盖板20的边缘的上方或下方；侧部12的内壁设置有用于支撑所述压力传感器50及盖板20的支撑件60。即压力传感器50在盖板20的边缘的上方或下方形成一环状(或近似环状)结构。支撑件60位于壳体10的侧部12的内壁，其可以支撑压力传感器50及盖板20。所以，当用户在盖板20上操作时，通过压力传感器50可以识别用户的触摸压力，同时，当盖板20及压力传感器50在用户压力作用下向下发生形变时，由于支撑件60的支撑，其可以避免盖板20及压力传感器50塌陷或脱离，进而可以提高触控设备的结构的稳定性及产品性能的稳定性。
本申请提供的压力传感器50可以位于盖板20的边缘的上方或下方，其中，压力传感器50可以通过自容或者互容的方式实现压力检测。
本申请具体的工作原理结合优选实施例说明如下：
实施例一：压力传感器50设置于所述盖板20的边缘的上方。
参见图2-图4，压力传感器50包括第一电极51、第二电极53及位于所述第一电极51及第二电极53之间的可随触摸压力形变的第一弹性件52，所述第一电极51与第二电极53形成可随触摸压力改变的形变电容。将第一电极51与第二电极53形成的形变电容与检测芯片电连接，检测芯片通过检测形变电容在有无触摸前后的电容值的改变来检测触摸压力。其中，检测芯片不局限于触控芯片或其它具有信号处理功能的部件。具体地，在压力传感器50上设置屏蔽电极55，以屏蔽外界信号的干扰，进而提高压力检测的准确度。具体的，可以在第一电极51、或者第二电极53或者同时在第一电极51及第二电极53上设置屏蔽电极55，以屏蔽减少外界的干扰。屏蔽电极55与压力传感器50上的第一电极51及第二电极53通过绝缘件56电隔离，即在第一电极51、或者第二电极53或者同时在第一电极51及第二电极53上设置绝缘件56后设置屏蔽电极55。所述支撑件60位于所述盖板20下方，所以，当用户触摸按压触控设备时，盖板20及压力传感器50在向下发生形变时，支撑件60可以支撑盖板20及压力传感器50，进而避免盖板20及压力传感器50塌陷或脱离。支撑件60可以通过多种方式设置于侧部12的内壁，例如 将支撑件60固定于或者可拆装的设置于侧部12的内壁，例如通过螺丝固定于侧部12的内壁，以提高支撑件60的稳固性，进而提升触控设备的结构即性能稳定性。支撑件60可以为多种形状，具体地，支撑件60呈倒L型，其有利于支撑件60固定于壳体10的侧部12，同时，支撑件60的水平部可以更好的支撑其上方的部件，例如更好的支撑其上方的盖板20。
在具体地实施例中，所述压力传感器还可以为单层电极的结构(单层电极可以为一个整体的电极，也可以为多个子电极组合形成单层电极的压力传感器，壳体10的顶部13为导电件，所述压力传感器50与顶部13之间设置有可随触摸压力形变的第二弹性件54，所述压力传感器50与所述顶部13形成可随触摸压力改变的形变电容；即此时压力传感器50为一导电件，其与壳体10的顶部13形成形变电容。形变电容与检测芯片电连接，检测芯片通过检测形变电容在有无触摸前后的电容值的改变来检测触摸压力。具体的，当用户触摸盖板20时，设置于盖板20上方的压力传感器50附带第二弹性件54一起向下移位形变，进而压力传感器50与顶部13的间距增大，形变电容的电容值发生改变，通过该电容值的改变即可检测识别用户的触摸压力。
具体地，压力传感器50位于盖板20的边缘的上方时，压力传感器50贴合于所述顶部13和/或所述盖板20上，压力传感器50的底部11与盖板20连接，压力传感器50可以随盖板20的移位而移位，进而使得形变电容的电容值发生改变。该结构简单、且安装稳固，成本较低。值得说明的是，压力传感器50可以与盖板20直接贴合也可以通过其他的方式连接以实现压力传感器50随盖板20的移位而移位。
实施例二：压力传感器50设置于所述盖板20的边缘的下方。
参见图5图9，压力传感器50包括第一电极51、第二电极53及位于所述第一电极51及第二电极53之间的可随触摸压力形变的第一弹性件52，所述第一电极51与第二电极53形成可随触摸压力改变的形变电容。将第一电极51与第二电极53形成的形变电容与检测芯片电连接，检测芯片通过检测形变电容在有无触摸前后的电容值的改变来检测触摸压力。具体地，在压力传感器50上设置屏蔽电极55，以屏蔽外界信号的干扰，进而提高压力检测的准确度。具体的，可以在第一电极51、或者第二电极53或者同时在第一电极51及第二电极53上设置屏蔽电极55，以屏蔽减少外界的干扰。屏蔽电 极55与压力传感器50上的第一电极51及第二电极53通过绝缘件56电隔离，即在第一电极51、或者第二电极53或者同时在第一电极51及第二电极53上设置绝缘件56后设置屏蔽电极55。
所述支撑件60位于所述压力传感器50的下方(则支撑件60必然位于盖板20的下方，即无论压力传感器所放置的位置,支撑件都位于盖板以下)，所以，当用户触摸按压触控设备时，盖板20及压力传感器50在向下发生形变时，支撑件60可以支撑盖板20及压力传感器50，进而避免盖板20及压力传感器50塌陷或脱离。同理，支撑件60可以通过多种方式设置于侧部12的内壁，例如将支撑件60固定于或者可拆装的设置于侧部12的内壁，例如通过螺丝固定于侧部12的内壁，以提高支撑件60的稳固性，进而提升触控设备的结构即性能稳定性。支撑件60可以为多种形状，具体地，支撑件60呈倒L型，其有利于支撑件60固定于壳体10的侧部12，同时，支撑件60的水平部可以更好的支撑其上方的部件，例如更好的支撑其上方的压力传感器50及盖板20。
在具体地实施例中，所述压力传感器还可以为单个电极的结构，所述支撑件60为导电件，所述压力传感器50与支撑件60之间设置有可随触摸压力形变的第二弹性件54，所述压力传感器50与所述支撑件60形成可随触摸压力改变的形变电容。即此时压力传感器50为一导电件，其与支撑件60形成形变电容，以检测压力。具体的，当用户触摸盖板20时，设置于盖板20下方的压力传感器50附带第二弹性件54一起向下移位形变，进而压力传感器50与支撑件60间距减小，形变电容的电容值发生改变，通过该电容值的改变即可检测识别用户的触摸压力。
具体地，压力传感器50位于盖板20的边缘的下方时，所述压力传感器50贴合于所述支撑件60和/或所述盖板20上。压力传感器50的顶部13与盖板20连接，压力传感器50可以随盖板20的移位而移位，进而使得形变电容的电容值发生改变。该结构简单、且安装稳固，成本较低。值得说明的是，压力传感器50可以与盖板20直接贴合也可以通过其他的方式连接以实现压力传感器50随盖板20的移位而移位(例如，压力传感器50通过粘合胶粘贴到盖板20上)。具体地，本申请中的壳体的顶部与侧部一体成型，壳体的底部与上述一体成型的结构连接，以便于触控设备的安装且保证触控设备的稳 固性。
综上，压力传感器50可以为一单独的电极，以与壳体10的顶部13或者与支撑件60形成形变电容，或者压力传感器50为包括有两个电极及位于两个电极之间的弹性件构成。同时，本申请提供的具有压力检测且可以倒装及避免塌陷的触控设备中的压力传感器50不局限于上述结构，例如，压力传感器50可以为压阻式传感器，以通过阻值的改变识别压力，其也可以为压电式传感器或压感式传感器。
压力传感器50可以为各种形状结构，具体地，所述压力传感器50呈连续的环状或包括若干个子传感器57，所述若干个子传感器57围合呈环状。其可以有效检测压力的同时，其结构简单、成本较低。若干个子传感器57可以为各种形状，更具体地，子传感器57呈方形，其检测到的压力更准确。具体地，支撑件60呈倒L型，则支撑件60的纵面可以更好的固定于所述侧部12的内壁，支撑件60的水平部分可以更好的与压力传感器50形成形变电容。
以上所述第一弹性件52和第二弹性件54可以是空气也可以是柔性填充物，例如，第一弹性件52和第二弹性件54可以为不带粘性的或仅一面带粘性或双面均具有粘性的粘合件，例如，第一弹性件52和第二弹性件54为硅胶、橡胶圈、粘合胶、泡棉等等。
在上述实施例中，压力传感器为一层电极实现压力检测时，其可节省成本；同时，当第一弹性件及第二弹性件为粘合胶时，其可以形成两处密封层，可以提高电子产品的防水性能。
以上对上、下方位的描述是以用户通常看到的触控产品的方位进行说明，例如在智能手表中，用户通常看到的为盖板，即相当于为手表的正面视图。以上所述上方、下方均为相对位置。
本申请中显示器件可以为各种具有显示功能的器件，例如，不局限于为LCD式显示器件，或者LED式显示器(包括OLED式显示器件)。
综上所述，本申请提供的触控设备适用于倒装结构，其具有压力检测的功能，且可以避免塌陷和脱离，进而可以提高产品的结构的稳定性及性能的稳定性。本申请还提供了一种电子终端，其包括上述任意结构的触控设备。例如，电子终端可以为智能手环、智能手表、智能手机，上述壳体即为手机的中框或者为手表的表壳。电子终端如果为正装结构，则其显示屏周围会存 在一圈黑边(黑色不可显示的区域)，例如当手机亮屏时，正装结构的手机在屏幕的周围(靠近手机壳体的边缘处)存在黑色不可显示的区域。通过本申请提供的具有倒装结构的电子终端，其可以通过壳体的顶部遮挡住所述黑边，进而用户在电子产品亮屏时看不到黑边，进而提高了产品的美观性和时尚性。
尽管已描述了本申请的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本申请范围的所有变更和修改。显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
