本发明要求在2018年11月9日提交至中国专利局、申请号为201811332383.7、发明名称为“柔性屏收纳装置、柔性屏拉伸量测量方法及终端”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本发明实施例涉及移动终端技术领域，特别涉及一种柔性屏收纳装置、柔性屏拉伸量测量方法及终端。
背景技术
大屏幕终端可以给用户带来更好的上网、游戏及视听影音享受，但却不便于携带；小屏幕终端方便携带，但在上网、游戏或视频时体验较差。因此需要一种可以根据用户需要，改变显示面积大小的终端，能够兼具大屏的感官享受以及小屏的方便携带的双重优点。
为了满足这一需求，折叠双屏终端和可变形柔性屏终端应运而生。柔性屏可以自由弯曲，它使显示类智能终端产品能够摆脱固有的刚性结构，实现更加多样化的结构形式，如弯曲造型、屏幕卷曲收纳等，从而减小显示类智能终端产品的体积，使得柔性屏手机能够根据用户需要改变实际显示面积的大小，从而能够兼具大屏的感官享受以及小屏的方便携带的双重优点。此类产品已成为智能终端产品的重要发展方向。
目前已经量产的折叠双屏手机，以及很多针对折叠柔性屏手机的专利和技术，主要是应用霍尔器件传感器对手机的旋转状态进行测量和判断。折叠双屏手机和折叠柔性屏手机的旋转状态主要有三种：折叠状态、展平状态和帐篷状态。
霍尔器件传感器主要由霍尔器件和磁体两部分组成，霍尔器件在磁体的磁场内会产生霍尔电压。将霍尔器件和磁体分别设置在左右两扇屏幕边缘，在垂直于磁体磁感线的方向上，磁场强度随着距离磁体远近变化而变化，距离磁体越远，磁场强度越小；同时，霍尔电压随磁场强度的变化而变化，磁场越强，电压越高；磁场越弱，电压越低。因此，可以通过测量霍尔电压数 值，得知折叠双屏手机和折叠柔性屏手机处于何种旋转状态。
然而，发明人发现，在一些情形下至少存在如下问题：在实际使用时，由于磁体的磁场强度会受到周围环境的影响，且折叠屏幕旋转角度与霍尔电压之间并不是线性关系，较难通过霍尔器件传感器准确测量出折叠屏幕的旋转角度，因此霍尔器件大多只能测量一个大致角度范围或只用于判断折叠屏幕的折叠和打开两种状态。而当柔性屏应用于可动态卷曲收纳和自由扩展的智能设备上时，柔性屏的显示面积在连续变化中，现有的霍尔器件传感器就很难准确测量动态变化柔性屏的扩展面积。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合附图对本发明的各实施方式进行详细的阐述。然而，本领域的普通技术人员可以理解，在本发明各实施方式中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施方式的种种变化和修改，也可以实现本申请所要求保护的技术方案。
本发明的第一实施方式涉及一种柔性屏收纳装置。在柔性屏卷曲收纳时，柔性屏的有效显示面积在不断减小，需要实时准确地测量出进入收纳结构的无效柔性屏区域，才能及时关闭无效柔性屏区域的显示功能，以达到节省电量的作用。在柔性屏自由扩展时，柔性屏的有效显示面积在不断扩大，需要实时准确地测量出从收纳结构中释放出来的柔性屏区域，才能及时激活新释放出柔性屏区域的显示功能，使扩大的柔性屏区域能够正常进行显示。
本发明实施方式通过将柔性屏的卷曲和收纳时的机械运动信号转换为电信号，使得在柔性屏动态卷曲收纳和自由扩展过程中，能够实时准确地测量出柔性屏的显示面积，从而为合理控制显示图像的长宽比例提供必要的数据支持。
本发明实施方式的柔性屏收纳装置的结构外形图如图1所示、结构透视图如图2所示、结构拆解图如图3所示。主要包括四个部分：收纳框1、卷筒2、中心轴3、导电触针4。
中心轴3设置在收纳框1内、且中心轴3的两端分别固定在收纳框1上； 卷筒2套设在中心轴3上且可旋转地容置于收纳框1内；柔性屏幕卷设于卷筒2的外表面上，柔性屏幕随着卷筒2的顺时针或逆时针运动，实现柔性屏幕的卷曲收纳或展平释放。
从图4中可以看出，卷筒2为圆柱形的中空结构，且其内表面开设有螺旋状凹槽结构。
中心轴3上缠绕有电阻丝；从图2可以看出导电触针4的一端嵌入中心轴内、且可沿中心轴3的轴向往复滑动并与电阻丝保持电导通，导电触针4的另一端可滑动地嵌入卷筒2的凹槽内。在柔性屏幕展平和收纳过程中，中心轴3固定不动，卷筒2转动时，带动嵌入卷筒2凹槽内的导电触针4在螺旋凹槽结构内滑动，同时在中心轴3的轴向往复滑动。
在一实施方式中，导电触针4的一端呈T型；中心轴3上沿长度方向开设有T形凹槽；导电触针4呈T型的一端嵌入中心轴3的T形凹槽内。
从图5、图6可以看出，中心轴3的轴向方向上开设有T形凹槽。从图7可以看出导电触针4的一端呈T型，且呈T型的一端嵌入中心轴3的T形凹槽内，导电触针4在被卷筒2带动时，沿中心轴3的轴向往复运动。
需要说明的是，参见图8，中心轴3为绝缘柱体，电阻丝8缠绕在绝缘柱体上，且电阻丝8凹陷于中心轴3的T形凹槽内，电阻丝8一端用引线引出，电阻丝8外围涂有绝缘漆。导电触针4与电阻丝接触的部分去掉绝缘。如图9所示，在导电触针4和电阻丝8一端施加电压，导电触针4在往复滑动过程中通过去掉绝缘漆的部分与电阻8保持电导通，电阻丝和导电触针4串联形成回路，回路中的电阻值大小就能够体现出导电触针4与电阻丝的接触位置，导电触针4与中心轴3上电阻丝8的接触位置距离电阻丝8用引线引出端的距离长短结合螺旋状凹槽的螺距能够计算出卷筒的转动圈数，从而体现出柔性屏的展开和收纳尺寸，因此，柔性屏卷曲和收纳的过程中，机械运动信号转换为电信号。
值得说明的是，中心轴3的电阻丝8可从中心轴3的一端缠绕至另外一端，也可仅缠绕住中心轴3的一部分。假设中心轴3的电阻丝8从中心轴3的一端缠绕至另外一端，那么在柔性屏幕全部卷曲于卷筒2内时，导电触针4位于卷筒2的一端，在柔性屏幕被拉伸时，导电触针4沿着螺旋状凹槽结构向卷筒2的另一端运动；且在柔性屏幕被拉伸完全时，导电触针4运动至卷筒2的另一端。
在柔性屏展开和收纳过程中，卷筒2转动时带动导电触针4沿中心轴3 的轴向往复滑动，且由于中心轴3上缠绕电阻丝8，而导电触针4在往复滑动过程中与电阻丝8保持电导通，所以在电阻丝8和导电触针4串联形成的电气结构两端施加电压时，电流回路中的电阻值大小就能够体现出导电触针4与电阻丝8的接触位置，导电触针4与中心轴3上电阻丝的接触位置距离电阻丝8用引线引出端的距离长短结合螺旋状凹槽的螺距能够计算出卷筒2的转动圈数，从而体现出柔性屏的展开和收纳尺寸，因此，柔性屏卷曲和收纳的过程中，机械运动信号转换为电信号，从而能够实时准确地测量出柔性屏的扩展面积，为合理控制显示图像的长宽比例提供必要的数据支持。
本发明的第二实施方式涉及一种终端，如图10所示，终端包括：扩展屏幕5、如第一实施方式中的柔性屏收纳装置6，扩展屏幕5为柔性屏，扩展屏幕5收纳在柔性屏收纳装置6内。
具体的说，本实施方式的终端为单向转轴形式的可扩展柔性屏设备，主要包括：柔性屏收纳装置6和扩展屏幕5两部分。扩展屏幕5在收缩状态时完全收纳在柔性屏收纳装置6内，在需要屏幕显示时才展平显示。柔性屏收纳装置6内部有一个圆柱形可转动的卷筒2，扩展屏幕5缠绕在卷筒2上，并随着卷筒2顺时针或逆时针转动，实现扩展屏幕5的卷曲收纳或展平释放。扩展屏幕5在展平和收纳过程中，露出面积在不断变化，可利用第一实施方式中的柔性屏收纳装置6获取有效显示面积，从而为合理控制显示图像的长宽比例提供必要的数据支持。
在一实施方式中，如图11所示，柔性屏收纳装置6的数量均为两个，扩展屏幕5包括两个固定边，两个固定边分别固定在两个柔性屏收纳装置6的卷筒2上，扩展屏幕5收纳在两个柔性屏收纳装置6内。

在一实施方式中，如图13所示，扩展屏幕5及柔性屏收纳装置6的数量均为两个；两个扩展屏幕5的拼接边与主体屏幕7拼接成一张显示屏，两个扩展屏幕5的固定边分别固定在柔性屏收纳装置6的卷筒2上，两个扩展屏幕5分别收纳在两个柔性屏收纳装置6。

与现有技术相比，本实施方式中提供了四种可扩展柔性屏终端，所有可扩展柔性屏重要的卷曲收纳结构内部都有一个如第一实施方式的柔性屏收纳 装置，可利用该柔性屏收纳装置获取四种可扩展柔性屏终端的有效显示面积，从而为合理控制显示图像的长宽比例提供必要的数据支持。
本发明的第三实施方式涉及一种柔性屏拉伸量测量方法，应用于第一实施方式中的柔性屏收纳装置。
本实施方式中的柔性屏拉伸量测量方法的流程示意图如图14示，具体包括：
步骤101：在卷起或释放柔性屏的过程中，检测导电触针在中心轴的轴向方向上的滑动距离。
具体的说，本发明的柔性屏与圆柱形卷筒运动过程如图15至图19所示。在柔性屏幕完全收纳状态时，导电触针4处于图15所示的A位置。
当需要逐渐释放柔性屏幕时，收纳框1开始沿着图16和图17中弯曲箭头所示方向逆时针转动，并逐渐释放柔性屏幕。收纳框1内表面的螺旋凹槽随之发生转动，导电触针4嵌入收纳框1内表面螺旋凹槽内，在螺旋凹槽转动的带动下，沿着螺旋凹槽滑动；导电触针4的T型部嵌入中心轴3上的T形凹槽内，并在T形凹槽内沿着图17中直线箭头所示方向做横向滑动，运动到图16和图17所示的B位置。
收纳框1继续逆时针转动，直到柔性屏幕完全释放展平，状态如图18所示，此时导电触针4已经横向运动到图18所示的C位置。
在需要柔性屏幕卷曲收纳时，收纳框1开始沿着图19中弯曲箭头所示方向顺时针转动，并逐渐收回柔性屏幕，收纳框1内表面的螺旋凹槽随之发生转动，导电触针4嵌入收纳框1内表面螺旋凹槽内，在螺旋凹槽转动的带动下，沿着螺旋凹槽滑动；导电触针4的T型部嵌入中心轴3上的T形凹槽内，并在T形凹槽内沿着图19中直线箭头所示方向做横向滑动，从图18所示的C位置运动回图19所示的B位置。
具体地，检测导电触针4在中心轴3的轴向方向上的滑动距离的步骤，具体包括：在中心轴3上电阻丝一端和导电触针4之间施加电压，检测通过导电触针4的电流值；根据电流值以及施加电压的电压值得到当前回路的电阻值；根据当前回路的电阻值以及中心轴3上电阻丝的总阻值计算导电触针4的滑动距离。
由于中心轴3上缠绕有电阻丝，总长度的电阻值R0固定。在中心轴3的电阻丝一端和导电触针4之间施加电压U，并通过测量产生的电流I，可 以通过欧姆定律计算得到中心轴3端部和导电触针4之间的实时电阻值为R＝U/I。进而可以计算出导电触针4在中心轴3上的凹槽内的横向滑动距离X＝R/R0。
步骤102：根据滑动距离以及卷筒内螺旋状凹槽的螺距计算卷筒的转动圈数。
具体地说，收纳框1内表面螺旋凹槽的螺距为M，即沿螺旋线方向量得的，相邻两螺纹之间的距离为M，则收纳框1的转动圈数T＝X/M，结合以上内容可以得出：T＝U/(M*I*R0)。
步骤103：根据转动圈数以及卷筒的周长获取柔性屏的拉伸长度。
具体地说，收纳框1的外部直径为D，收纳框1每旋转一圈，柔性屏幕的扩展宽度即为收纳框1的外部周长πD，因而可以得出柔性屏幕的扩展宽度L＝πDT，结合上述内容可以得出，L＝πDT＝(π*D*U)/(M*I*R0)。
步骤104：根据拉伸长度和柔性屏的宽度计算出柔性屏的拉伸面积。
具体地说，将收纳框1和其上柔性屏幕的旋转圆周运动，转化为导电触针4的横向水平运动，最终根据欧姆定律测量实时电压电流等电信号数值，通过计算得到柔性屏幕实时扩展宽度L，从而据拉伸长度和柔性屏的宽度计算出柔性屏的拉伸面积(即有效显示面积)。
在一实施方式中，中心轴内表面螺旋凹槽的螺距为M，即沿螺旋线方向量得的，相邻两螺纹之间的距离为M，则中心轴的转动角度θ＝(X/M)*360°＝[U/(M*I*R0)]*360。
与现有技术相比，本发明实施方式，提供了一种柔性屏拉伸量测量方法，应用于上述的柔性屏收纳装置；柔性屏拉伸量测量方法包括：在卷起或释放所述柔性屏的过程中，检测所述导电触针在中心轴的轴向方向上的滑动距离；根据滑动距离获取卷筒的转动圈数；根据转动圈数以及卷筒的周长获取柔性屏的拉伸长度；根据拉伸长度和柔性屏的宽度计算出柔性屏的拉伸面积。通过以上测量方法在柔性屏动态卷曲收纳和自由扩展过程中，能够实时准确地测量出柔性屏的显示面积，从而为合理控制显示图像的长宽比例提供必要的数据支持。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范 围内。

其中，存储器202和处理器201采用总线方式连接，总线可以包括任意数量的互联的总线和桥，总线将一个或多个处理器和存储器202的各种电路连接在一起。总线还可以将诸如外围设备、稳压器和功率管理电路等之类的各种其他电路连接在一起，这些都是本领域所公知的，因此，本文不再对其进行进一步描述。总线接口在总线和收发机之间提供接口。收发机可以是一个元件，也可以是多个元件，比如多个接收器和发送器，提供用于在传输介质上与各种其他装置通信的单元。经处理器处理的数据通过天线在无线介质上进行传输，进一步，天线还接收数据并将数据传送给处理器201。
处理器201负责管理总线和通常的处理，还可以提供各种功能，包括定时，外围接口，电压调节、电源管理以及其他控制功能。而存储器202可以被用于存储处理器在执行操作时所使用的数据。
