发明实施例
本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
压力感应装置的实施例：
实施例一：
请参阅图1至图3，下面对本发明的压力感应装置的实施例一进行阐述。
本实施例的触控电子设备可以为触控掌上电脑，亦可为触控显示设备；而该压力感应装置100，包括上面板10、第一感应板件20、第二感应板件30、及控制电路板40，下面对压力感应装置100的各部件作进一步说明：
上面板10为可供实施者施加压力，其中，该上面板10为具有刚性结构的面板，那么，在用户触按上面板10时，上面板10自身能维持本身的状态不发生变化，或不发生明显变形。具体地，在实施者向上面板10上施加压力时，上面板10本身不发生具有塌陷意义上的变形，或上面板10的变形远远小于上面板10与第一感应板件20的间距。另外，若触控电子设备为触控掌上电脑时，上面板10可以设置为1.1mm厚度的玻璃板；若触控电子设备为触控显示设备时，上面板10可以设置为1.6mm厚的LCD液晶面板。同时地，该上面板10可以为具有触摸功能和显示功能的电子组件；
第一感应板件20为可感应作用于其上的外部压力，其中，该第一感应板件20包 括上端21及与上端21相对设置的下端22，且该第一感应板件20上设有可将外部压力集中感应的镂空区域23，镂空区域23包括用以将外部压力集中于一点位置处的压力集中点位230，位于第一感应板件20的上端21的镂空区域23通过一第一连接材料50与上面板10连接；
第二感应板件30为可感应作用于其上的外部压力，其覆设有压力感应膜，其中，该第二感应板件30与第一感应板件20的下端22贴合连接；较佳地，该第二感应板件30可以为印刷具有压力感应性能的聚合物涂层的板件，或者，可以是具有烧结的压电陶瓷涂层的板件，但本实施例的实施不限于此；另外，该第二感应板件30可采用量子隧道复合物、电容性传感器或其他压力敏感电阻器技术制备而成；
控制电路板40为用以根据实施者施加的压力信息以控制触控电子设备进行相应的工作，该控制电路板40与第二感应板30电连接。那么，可理解为，该控制电路板40为具有多种处理方法的硬件、软件的组合，而这些硬件、软件被配置成可将第二感应板30输入的控制信息通过反馈或与客户相关联的***进行通讯并执行附加的相关任务或功能。此外，该控制电路板40的板体上集成有处理器、内容可寻址存储器、数字信号处理器、数模转换开关、可编程逻辑器件、分立的硬件组成和/或其他组合；同时，其内部还内嵌有与上面板10和/或压力感应***相关的算法、软件信息的功能模块。
由于本实施例的压力感应装置100于第一感应板件20上设有镂空区域23，而该镂空区域23包括压力集中点位230，由此，当实施者向上面板10施加一定压力时，该压力会通过第一连接材料50传至第一感应板件20，而第一感应板件20受力后，该作用力会被集中在镂空区域23的压力集中点位230，保证实施者的按压精准，接着，该作用力会传至第二感应板件30，再由控制电路板40根据第二感应板件30传来的实施者施加的压力信息以控制触控电子设备进行相应的工作，可见，整个触摸按压操作简单方便，易于测量；同时，该压力感应装置100结构简单，加工方便，生产成本低，有利于压力感应装置100的推广使用。
请参阅图3，作为本实施例的优选方案，该镂空区域23设有至少四个，该至少四个镂空区域23均匀分设于第一感应板件20的四周，以使作用于第二感应板件2 0的作用力可以分别集中在第一感应板件20的四周，有利于将压力传至指定区域并集中。优选地，该镂空区域23设有四个，以便于生产加工，而本实施例也以镂空区域23设有四个作为述说。
请继续参阅图3，为了更有利于外部压力集中在压力集中点位230上，本实施例的镂空区域23还包括沿压力集中点位230的四周侧端延伸设置的至少两个第一延伸空位231，其中，为了简化结构及便于生产加工，在本实施例中，第一延伸空位231设有两个。
另外，在相邻的第一延伸空位231之间为第一感应板件20的实体部分，换言之，该第一延伸空位231汇集在压力集中点位230处，相邻第一延伸空位231之间的第一感应板件20的实体部分则形成悬臂结构233，从而，当有压力或其它作用力作用在第一感应板件20的镂空区域23上后，压力可被集中在镂空区域23的压力集中点位230处。另外，在采用第一连接材料50以将位于第一感应板件20的上端21的镂空区域23与上面板10连接时，该第一连接材料50主要为一端与上面板10连接，而另一端与镂空区域23的悬臂结构233连接。
同时地，为了便于生产设置，该第一延伸空位231呈横向条状结构，当然，亦可将其设置为其它形状结构，如弧状，因此，本实施例的第一延伸空位231的形状结构的保护不限于此。
请再参阅图3，较佳地，该两个第一延伸空位231为对称设置或不对称设置，而在本实施例中，将该两个第一延伸空位231设置为对称设置，亦即，其中一个第一延伸空位231以压力集中点位230的中心作为旋转点旋转180度与另一个第一延伸空位231重合，据此，可进一步有利于压力或作用力均匀集中在压力集中点位230处。
再有，任一第一延伸空位231的延伸末端的两侧延伸有第二延伸空位232，以进一步使到压力汇集在压力集中点位230处；而且，该两个第二延伸空位232为对称设置或不对称设置，具体地，在本实施例中，该该两个第二延伸空位232为对称设置，亦即，其中一个第二延伸空位232以压力集中点位230的中心作为旋转点旋转180度与另一个第二延伸空位重合，以更进一步有利于压力或作用力均匀集中在压力集中点位230处。较佳地，为了便于生产设置，该第二延伸空位232 呈横向条状结构，而且该四个第二延伸空位232为互相不连接。
再有，为了便于第一感应板件20的固定，在第一感应板件20的外周设置有固定结构，以便于当第一感应板件20设置在第二感应板件30上后，其可以固定位置。
具体地，上述的固定结构包括固定边条，该固定边条设置在第一感应板件20的外周亦可选择地，第一感应板件20上的固定结构还可以是其它多种形式结构，如布置在力集中感应板件12周边的支撑筋等等。
请参阅图1和图2，本实施例的第二感应板件30包括压力感应层(图中未标示)以及设置在压力感应层上的感应部件(图中未标示)，镂空区域23与感应部件呈对齐设置，以便于压力集中在压力集中点位230时，可将压力迅速传至第二感应板件30的感应部件上，有利于第二感应板件30对该压力作下一步操作。
其中，较佳地，该感应部件为具有压力感应作用的涂层或线路。
请再参阅图1和图2，本实施例的第一连接材料50为可将上面板10与第一感应板件20两者连接并使该两者形成间隔距离的双面胶、亚克力发泡胶、UV胶、AB胶或硅胶，具体地，一方面，第一连接材料50的主要作用为间隔上面板10与第一感应板件20两者，使得上面板10在外力作用下保持与第一感应板件20相分离；另一方面，第一连接材料50的作用为将上面板10受到的压力传递到第一感应板件20的镂空区域23的悬臂结构233上。在本实施例中，第一连接材料50选择为亚克力发泡胶时，较佳地，亚克力发泡胶为VHB亚克力发泡胶，该VHB亚克力发泡胶为方形结构且其厚度为0.6mm；当然，第一连接材料50也可选择为UV胶，其中，该UV胶通过点胶形成，且其高度为0.3mm，同时，也要保证所有UV胶均与上面板10与第一感应板件20两者连接。
在本实施例中，为了使到第二感应板件30与第一感应板件20紧密连接，第二感应板件30通过第二连接材料60与第一感应板件20的下端连接，且第二连接材料60为双面胶、亚克力发泡胶、UV胶、AB胶或硅胶。
另外，本实施例的控制电路板40通过连接线70与第二感应板30电连接，具体为，连接线70的一端焊接于控制电路板40，另一端焊接于第二感应板30。
下面结合各图式，对本实施例的压力感应装置100的工作原理作进一步说明：
当实施者向上面板10施加一定压力时，该压力会通过第一连接材料50传至第一感应板件20，而第一感应板件20受力后，该作用力会被集中在镂空区域23的压力集中点位230，由此，该压力会被传至压力集中点位230附近的悬臂结构233上，而悬臂结构233受力后会产生变形，此时，贴设于第一感应板件20的下端22的第二感应板件30可检测到悬臂结构233的变形，从而第二感应板件30可以感应到施加在上面板10上的压力；此时，压力电信号通过连接线70传递到控制电路板40，再由控制电路板40根据第二感应板件30传来的实施者施加的压力电信号以控制触控电子设备进行相应的工作。
