实施例3
本实施例是根据本发明的可选实施例，用于对本申请进行具体详细的说明：
本实施例描述了一种弯曲检测装置及办法，其实现方式和结构组成简单，且能够实现各个位置的精确测量。
本实施例引入了电阻应变式传感器，传感器中的电阻应变片具有金属的应变效应，即在外力作用下产生机械形变，从而使电阻值随之发生相应的变化，通过检测电阻变化即可判断当前设备的弯曲形变程度。本专利方案中的电阻应变式传感器并非独立的器件，而是直接集成在电容触摸屏的线路中，同触摸屏一体，遍布终端的全部位置，可以确保检测的全面性和 精确度。
本实施例做到了将触摸屏和弯曲检测装置的整合，结构简单，易于实现。
本实施例将电阻应变式传感器集成在现有的触摸屏线路中，做到全面和精确的弯曲检测。传感器中的电阻应变片具有金属的应变效应，即在外力作用下产生机械形变，从而使电阻值随之发生相应的变化，通过检测电阻变化即可判断当前设备的弯曲位置和形变程度。
本实施例还提供了一种用于实现该方法的装置，该装置包括触摸及弯曲检测模块、显示模块和基带处理模块，其中显示模块、基带处理模块和当前常见无线终端设备的现有部分相同。本发明中触摸及弯曲检测模块和显示模块均与基带处理模块相连，基带处理模块根据触摸及弯曲检测模块传递来的信息，可以控制相应模块执行某些操作，包括但不限于控制显示模块对当前显示画面进行调整。
具体的，的触摸及弯曲检测模块：在触摸屏内部线路中的，串联有数个电阻应变式传感器，传感器均匀分布在触摸屏所在区域的各个位置。当手机发生弯曲时，对应弯曲发生位置的触感器中的电阻应变片发生机械形变，进而带来电阻值的变化，触摸及弯曲检测模块通过检测各个线路上的电阻变化，即可判断当前发生弯曲的位置，以及弯曲幅度的大小。
基带处理模块：配置为接收触摸及弯曲检测模块传递来的信息，并根据信息内容，控制相应模块执行某些操作，包括但不限于控制显示模块对当前显示画面进行调整。
显示模块：配置为在基带处理模块的控制下，显示和调整当前画面信息。
与相关技术相比较，本发明用较为简单的方式实现全面和精确的弯曲检测，该方法及其装置设计巧妙、逻辑清晰、结构简单、易于实现。
图5为本发明实施例装置组成示意图，如图5所示，本发明实施例的装置包括：触摸及弯曲检测模块50、显示模块52、基带处理模块54，其中，触摸及弯曲检测模块和显示模块均与基带处理模块相连。
触摸及弯曲检测模块，其实现方式是在现有的触摸屏线路中，串联数个电阻应变式传感器，形成检测网络均匀分布在触摸屏所在区域的各个位置。每个电阻应变式传感器均由一个电阻应变片组成，当手机发生弯曲时，对应弯曲发生位置的电阻应变片发生机械形变，进而带来电阻值的变化，触摸及弯曲检测模块通过检测各个线路上的电阻变化，即可判断当前发生弯曲的位置，以及弯曲幅度的大小，并最终将弯曲检测信息传递给基带处理模块。同时，触摸及弯曲检测模块还具备常规的触控功能，其同样将检测到的触控信息传递给基带处理模块，
基带处理模块，接收触摸及弯曲检测模块传递来的信息，并根据信息内容，控制相应模块执行某些操作，包括但不限于控制显示模块对当前显示画面进行调整。
显示模块：配置为在基带处理模块的控制下，显示和调整当前画面信息。显示模块在物理空间上位于触摸及弯曲检测模块的下方，二者紧密连接或者贴合。
图6为本发明实施例的方法处理流程示意图，如图6所示，本实施例实现弯曲检测功能包括以下步骤：
步骤601：用户操作手机发生弯曲；
步骤602：触摸及弯曲检测模块中，对应弯曲发生位置的电阻应变式传感器内的电阻应变片的电阻值发生变化；
步骤603：触摸及弯曲检测模块将包含有弯曲位置、弯曲幅度的检测信息传递给基带处理模块；
步骤604：基带处理模块根据接收到的信息，控制某些模块执行相关操 作，包括但不限于控制显示模块对当前显示画面进行调整；
步骤605：流程结束；
图7为本发明实施例的检测原理示意图，如图7所示，下面对本发明实施例的实现原理进行介绍：
触摸及弯曲检测模块内部有数个电阻应变式传感器，每个电阻应变式传感器均由一个电阻应变片组成，电阻应变片的基本结构如图7，它一般由敏感栅、基底、引线、盖片等部分组成。敏感栅通常由直径为0.01-0.05mm、高电阻系数的金属细丝弯曲而成栅状，并用粘合剂固定在基底上。盖片用于保护敏感栅，引线用于将电阻应变片与测量电路相连接。
实际应用中，可以将电阻应变片用粘合剂牢固地粘贴在被测试件的表面上，当被测试件发生形变时，基底将被测试件上的形变准确地传递到敏感栅上，随着敏感栅发生同样的形变，其本身电阻值发生变化，且电阻值的变化与被测试件的形变幅度成正比，被测试件形变量越大，则敏感栅的电阻增量越大；通过一定的测量线路将这种电阻变化转换为电压或电流变化，即可获取被测试件形变量的大小。
而在本实施例的方案中，可以不再借助基底传递形变，而是直接将敏感栅串联在触摸屏线路中，当设备发生弯曲时，触摸屏同步发生弯曲，对应形变发生位置的敏感栅的电阻值将发生变化，且电阻值的变化量将反映出设备的弯曲程度。
图8为本发明实施例的结构组成示意图，如图8所示，根据不同的场景，包括：图(1)、图(2)图(3)，为本发明实施例的结构组成如下：
图(1)为自电容屏和互电容屏的触控检测示意图，左图的自电容屏示意图中，通过检测X线路(即图中的X0-X3)和Y线路(即图中的Y0-Y3)各自对地之间的电容变化，可以判断当前的触控位置；右图的互电容屏示意图中，通过检测X线路和Y线路之间的电容变化，可以判断当前的触控位 置。
图(2)所示的方案中，如图中所示，无论是自电容屏还是互电容屏，在现有X线路和Y线路的每个触控检测点之间，分别串入一个电阻应变式传感器，每个传感器中敏感栅的走向与其所在的X线路或者Y线路方向保持垂直。当X1线路所在位置发生弯曲时，形变将引发X1线路上串联的电阻应变式传感器的电阻值变化，且电阻值的增量与弯曲形变量成正比，同理，当Y1线路所在位置发生弯曲时，形变将引发Y1线路上串联的电阻应变式传感器的电阻值变化，且电阻值的增量与弯曲形变量成正比。若检测到X0到X3等多条线路的阻值增大，则可得知设备对应X0到X3线路的位置弯曲成为弧形，若此时X1线路的电阻值大于其它线路，则可知设备对应X1线路的位置处的弧度角(即形变量)最大。对于X线路和Y线路电阻变化的检测可以转换为对电压或电流变化的检测，比如在X线路和Y线路的一端加载一定值的电压和电流，当X线路和Y线路的电阻变大时，线路上产生的压降增大，此时在另一端检测到的电压值将减小；又或者在X线路和Y线路的两端加载一定值的电压，当X线路和Y线路的电阻变大时，通过X线路和Y线路上的电流将减小。
本方案中，弯曲检测功能与触摸功能的实现相互独立，因为触控位置的判断是通过检测X和Y线路对地之间的电容变化(自电容屏)，以及X和Y线路之间的电容变化(互电容屏)，而弯曲检测的实现是通过检测X和Y线路自身上的电阻值变化(即电压或者电流变化)，二者的检测信息获取来自于不同的维度。
图(3)是本专利方案另一种简化形式的结构组成示意图，如图中所示，无论是自电容屏还是互电容屏，在现有X线路和Y线路上，每间隔一定数量的触控检测点，串入一个电阻应变式传感器，每个传感器中敏感栅的走向与其所在的X线路或者Y线路方向保持垂直。只需要确保每条X线路和Y线路 上均分布有一定数量的电阻应变式传感器，则同样可以实现本专利的弯曲检测功能。
本实施例的弯曲检测装置可以单独使用，也可以和加速度传感器等可判断方向的传感器配合使用，通过弯曲检测装置，基带处理芯片可以获取当前设备的弯曲位置和弯曲程度，此时再通过加速度、地磁等传感器，基带处理芯片可以获取当前设备的方向信息，进而可以更加准确的实现一些功能。比如说根据弯曲检测信息，基带处理芯片调整当前显示区域的大小，再根据方向检测信息，将当前画面显示在朝向上方、面向人眼的显示区域中。
图9为本发明实施例的补充方案流程示意图，如图9所示，此时的实施例的步骤相比图6，本补充方案中增加了步骤904，基带处理芯片获取弯曲检测信息后，再次获取方向检测信息，进而控制某些模块执行相关操作，包括但不限于控制显示模块对当前显示画面进行调整。
本实施例是采用电阻应变式传感器来实现弯曲检测，同时将其集成入触摸屏线路中，本方案技术简单、易于实现，在确保检测全面、准确的同时，降低了设备的复杂度和成本。
