具体实施方式
下面将结合本发明实施方式中的附图，对本发明实施方式中的技术方案进行清楚、完整地描述。
请参阅图1与图4，本发明实施例提供一种折叠机构及具有所述折叠机构的终端100。所述终端100可以是平板电脑、手机、柔性显示器、电子阅读器、遥控器、个人计算机(Personal Computer，PC)、笔记本电脑、车载设备、网络电视、可穿戴设备等。
请一并参阅图1，本发明实施例中，所述折叠机构包括支撑体1及设于所述支撑体1内的控制装置10，所述支撑体1至少部分为柔性，并且所述支撑体1的柔性部分填充有磁流变液，所述控制装置10用于控制所述磁流变液固化或者液化，以实现所述支撑体1的弯折及定位。具体的，当所述支撑体1全部为柔性时，即包括柔性外壳和填充于柔性外壳内的磁流变液。所述磁流变液液化时，支撑体1可以任意角度弯折，并且在所述磁流变液固化后定位于弯折的角度。而使用所述折叠机构的终端的柔性屏可以通过磁流变液固化后的支撑体1来支撑，而在磁流变液液化时任意角度弯折柔性屏，进而可以实现大屏幕显示性能，而且可以实现柔性屏任意角度弯折和角度定位。
本实施例中，所述支撑体1上设有传感器18，所述控制装置10与所述传感器18电连接，并在检测到传感器18的感测信号后控制所述磁流变液固化或 者液化。所述支撑体1上设有电磁铁17，所述控制装置10控制所述电磁铁17充电或者断电，以使所述电磁铁17对所述磁流变液产生磁场或者关闭磁场。
请参阅图2与图3，当所述支撑体1部分为柔性时，填充有磁流变液的柔性部分为柔性弯折部15，所述柔性弯折部15包括用于容纳所述磁流变液152的柔性外壳151，所述柔性弯折部15相对两侧连接的所述支撑体为第一支撑体和第二支撑体。所述控制装置10用于控制所述磁流变液152固化或者液化，以实现所述第一支撑体11相对第二支撑体13的定位或翻折。
所述第一支撑体11与第二支撑体13为矩形的中空壳体，也可以是板体，根据设计需要来确定，所述第一支撑体11与第二支撑体13内部可以用于收容电源、电路板灯器件。所述柔性外壳151为橡胶等柔性材料制成的矩形密封结构，内部充满磁流变液152，并且磁流变液152的固化或者变为液体来决定所述柔性外壳151的形态。所述柔性外壳151相对两侧分别连接所述第一支撑体11的一侧边和第二支撑体13的一侧边。所述第一支撑体11与第二支撑体13可以是塑料、金属等材质支撑。当然，也可以是具有支撑体支撑的柔性体，与所述柔性弯折部的柔性外壳151一体成型。所述第一支撑体11包括第一表面111上，所述第二支撑板13包括第二表面131，需要说明的是第一表面111与第二表面131可构成一平面并且朝向相同。
如图3，本实施例中，所述第一支撑体11内设有与所述控制装置10连接的电源16。所述控制装置10为柔性电路板或者印刷电路板所述控制装置10设于第二支撑体13内。当然，所述电源也可以设置于第二支撑体13内。所述控制装置10设置与所述第一支撑体11内。所述柔性折弯部15连接于所述第一支撑体11与第二支撑体13之间。所述柔性外壳151可以与所述第一支撑体11与第二支撑体13膜内双射成型再填充磁流变液，也可以是填充好磁流变液构成一个独立整体后通过热熔、胶体等固定方式连接固定。
所述第一支撑体11和/或所述第二支撑体13上设有所述电磁铁17，所述控制装置10控制所述电磁铁17充电或者断电，以使所述电磁铁对所述柔性折弯部15产生磁场或者关闭磁场。本实施例中，所述第一支撑体11和所述第二支撑体13上均设有电磁铁17。具体的，一所述电磁铁17位于所述第一支撑体11与所述柔性折弯部15的连接端部，另一所述电磁铁17位于所述第二支撑体13与所述柔性折弯部15的连接端部。两个电磁铁17距离所述柔性折弯 部15较近，磁场的产生和消失可以被柔性折弯部15的磁流变液152即时感应到，继而随时改变形态，以实现柔性折弯部15灵活的变形和固定。本实施例中，所述控制装置10为线路板。可以是属于折叠机构的控制电磁铁17的线路板，也可以是应用该折叠机构的终端的线路板。
当所述控制装置10为所述电磁铁17充电时，电磁铁17产生磁场，柔性折弯部15的磁流变液感应到磁场会瞬间固化，进而实现所述柔性折弯部15在任一形态而固定。那么当使用者使第一支撑体11相对第二支撑体13翻折后需要固定在某个角度，只要电磁铁17产生磁场，柔性折弯部15的磁流变液感应到磁场会瞬间固化即可以使柔性折弯部15在任意角度定位第一支撑体11与第二支撑体13的角度。当所述控制装置10为所述电磁铁17断电时，电磁铁17的磁场消失，柔性折弯部15的磁流变液152感应不到磁场会瞬间液化，所述柔性折弯部15可以360度的弯折。那么当使用者使第一支撑体11相对第二支撑体13翻折弯折过程中，只要电磁铁17的磁场消失柔性折弯部15的磁流变液液化即可以使柔性折弯部15在任意角度随着第一支撑体11与第二支撑体13翻折。那么柔性折弯部15不存在对抗的力，也不存在翻折角度的限定，其弯折性能较好，提高使用者的使用体验。
所述第一支撑体11和/或所述第二支撑体13内设有所述传感器18，所述控制装置10与所述传感器18电连接，并在检测到传感器18的感测信号后控制所述磁流变液152固化或者液化。所述传感器18在检测到操作信号时传递给所述控制装置10以控制所述电磁铁17充电或者断电。所述传感器18为压力传感器、距离传感器、指纹识别模组、拉力传感器、多点式传感器中的一种。本实施例中传感器18为压力传感器。
本实施例中，所述第一支撑体11和所述第二支撑体13上均设有所述传感器，并且所述第一支撑体11上的传感器18位于第一支撑体11远离所述柔性折弯部的端部，所述第二支撑体13上的传感器18位于远离第二支撑体13所述柔性折弯部15相对的端部。当使用者双手握住第一支撑体11和所述第二支撑体13对第一支撑体11和所述第二支撑体13进行翻折时，两个传感器18的位置为最方便握持的位置，当传感器18同时感测到操作信号并传递给所述控制装置10，控制装置10在检测到传感器18的感测信号后给电磁铁断电以控制所述磁流变液152液化，就可以使第一支撑体11和所述第二支撑体13通过 柔性折弯部15任意角的翻折。而当使用者找好第一支撑体11和所述第二支撑体13相对弯折角度后，会放开握持传感器18位置的手，只要一个传感器18感测到撤销操作的操作信号并传递给所述控制装置10，所述控制装置10为所述电磁铁17充电，柔性折弯部15的磁流变液152感应到磁场会瞬间固化，使所述柔性折弯部15在当前角度固定，第一支撑体11和所述第二支撑体13也就实现了翻折后角度的定位。在此过程中并不需要考虑柔性折弯部15的扭力，而且柔性折弯部15弯折的角度无需受到限制。
如图4，本发明实施例提供一种终端100，其包括柔性屏120和所述折叠机构，所述柔性屏120固定于所述第一支撑体11和所述第二支撑体13上。具体的，所述柔性屏120为矩形屏，其一部分装于所述第一支撑体11的第一表面111上，另一部分装设于所述第二支撑板13的第二表面131上，中间部分与所述柔性折弯部15相对层叠。所述控制装置10与所述柔性屏120电连接。而电源10也可以为所述柔性屏120提供电量。所述折叠机构实现对柔性屏120的支撑。当需要折叠所述柔性屏120或者调整柔性屏的观看角度时，使第一支撑体11相对所述第二支撑体13翻折带动柔性屏120翻折，比如需要收纳所述终端100，将柔性屏120对折，握持第一支撑体11相对所述第二支撑体13端部，传感器18感测到握持的操作信号并传递给所述控制装置10，所述控制装置10为所述电磁铁17断电，消除磁场，所述磁流变液152液化，就可以使第一支撑体11和所述第二支撑体13通过柔性折弯部15对折，进而将柔性屏120对折。然后松开第一支撑体11和所述第二支撑体13，所述控制装置10为所述电磁铁17充电来是电磁铁17产生磁场，磁流变液152感应到磁场会瞬间固化，使所述柔性折弯部15在当前角度固定。当需要展平柔性屏120时，使第一支撑体11相对所述第二支撑体13完全展开，第一表面111和第二表面131位于同一平面且朝向相同。
本发明所述的终端通过所述折叠机构支持和折叠所述柔性屏，在对柔性屏把持翻折的过程中就可以控制柔性折弯部15的弯折角度和固定状态，来实现柔性屏的翻折状态及定位，不会产生过多的扭力和阻力，操作随意简单，并且使所述终端具有较高的弯折性能。
所述柔性折弯部15的表面设有柔性支撑板(图未示)，所述柔性支撑板19与所述柔性屏120贴合并随柔性屏120的折弯区域的形变而变化。所述柔 性支撑板19在所述柔性屏120完全展开时，支撑所述柔性屏120与柔性折弯部15相对的折弯区域，以使柔性屏可以更好的展平。当柔性屏120弯折时，柔性支撑板19随着折弯区域而弯折，防止弯折区域受压或者弯折受损，起到保护的作用。
请参阅图5，本发明还提供上述折叠机构的控制方法，所述方法包括
步骤1、通过传感器18感测支撑体1被操作的操作信号，
步骤2、控制装置10收到传感器18传递的操作信号后为电磁铁17充电或者断电，以使电磁铁17为柔性折弯部的磁流变液152固化产生磁场，或者以使电磁铁17为柔性折弯部15的磁流变液152液化而消除磁场；以实现所述支撑体1的定位或者翻折。
当支撑体的柔性部分为柔性弯折部15时，所述支撑体1包括的所述第一支撑体11与第二支撑体13通过所述柔性折弯部15定位或者翻折。
其中，所述传感器18感测第一支撑体11与第二支撑体13被触碰，控制装置10收到传感器18传递的被触碰的操作信号后为电磁铁17断电，以使电磁铁17为柔性折弯部15的磁流变液152液化而消除磁场，所述第一支撑体11与第二支撑体13通过所述柔性折弯部15翻折角度。
其中，所述传感器18感测第一支撑体11与第二支撑体13撤销操作(手离开)的操作信号，控制装置10收到传感器18传递的撤销操作的操作信号后为电磁铁17充电，以使电磁铁17为柔性折弯部15的磁流变液152固化产生磁场，所述第一支撑体11与第二支撑体13通过所述柔性折弯部15定位。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
