柔性屏支撑结构、柔性显示屏模组及移动终端 技术领域
发明涉及电子设备领域，尤其涉及一种柔性屏支撑结构、柔性显示屏模组及移动终端。
背景技术
随着柔性显示技术的发展，柔性显示屏越来越多的应用于移动终端中，并利用柔性屏支撑结构实现柔性显示屏的收缩或展开。目前多数的移动终端存在折叠方式或者卷曲方式的两种柔性屏支撑结构。当移动终端采用折叠方式的柔性屏支撑结构时，柔性显示屏展开后方便利用板件进行支撑，但是折叠后不易于缩小体积；当移动终端采用卷曲方式的柔性屏支撑结构时，柔性显示屏可以卷曲而收缩体积，但是展开后没有支撑结构，不易对柔性屏支撑。因此目前没有一种既可以方便柔性显示屏收缩体积，展开后又方便对柔性显示屏进行支撑的柔性屏支撑结构。
发明内容
有鉴于此，发明提供一种方便收缩、方便支撑柔性显示屏的柔性屏支撑结构。

本发明还提供一种柔性显示屏模组，其中，所述柔性显示屏模组包括上述任意一项所述的柔性屏支撑结构，所述柔性显示屏模组还包括柔性显示屏，所述柔性显示屏贴合于所述多个电磁体上。
本发明还提供一种移动终端，其中，所述移动终端包括上述的柔性显示屏模组。

具体实施方式
下面将结合发明实施方式中的附图，对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和图2，发明提供的一种柔性屏支撑结构100，所述柔性屏支撑结构100包括多个电磁体10和电连接所述多个电磁体的控制器20。所述多个电磁体10用以固定于柔性显示屏1上。每一所述电磁体10具有固定于所述柔性显示屏1的支撑面11和与所述支撑面11呈锐角夹角的侧面12。并且每一所述电磁体10具并排于柔性显示屏1上的第一磁极S和第二磁极N。在所述柔性显示屏1展开时，所述控制器20控制一个所述电磁体10的第一磁极S与相邻一个所述电磁体10的第一磁极S相靠拢，或者控制一个所述电磁体10的第二磁极N与相邻一个所述电磁体10的第二磁极N相靠拢，进而使得相邻两个所述电磁体10的侧面12在同性磁极作用下相排斥。在所述柔性显示屏1弯曲时，所述控制器20控制一个所述电磁体10的第一磁性S与相邻一个所述电磁体10的第二磁极N相靠拢，进而使得相邻两个所述电磁体10的侧面12在异性磁极作用下相吸合。
可以理解的是，所述柔性屏支撑结构100应用于移动终端，所述控制器20控制预设位置处电磁体10的侧面12与相邻电磁体10的侧面12相排斥，从而实现对所述柔性显示屏1支撑；也可以是控制预设位置处电磁体10的侧面12与相邻电磁体10的侧面12相互吸合，从而实现所述电磁体10带动所述柔性显示屏1弯曲。该移动终端可以是手机、平板电脑或者笔记本电脑等。
通过在所述柔性显示屏1上密布多个所述电磁体10，而每一所述电磁体10具有并排于所述柔性显示屏1上的第一磁极S和第二磁极N；同时利用所述电磁体10，从而所述控制器20控制一个所述电磁体10的第一磁极S与相邻一个所述电磁体10的第一磁极S相靠拢，可以使得相邻两个所述电磁体10的侧面12受相同磁极排斥作用力下相互排斥而展开，进而所述多个电磁体10带动所述柔性显示屏1展开并对所述柔性显示屏1进行支撑；所述控制器20控制一个所述电磁体10的第一磁极S与相邻一个所述电磁体10的第二磁极N相靠拢，进而相邻两个所述电磁体10的侧面12在不同磁极的吸引作用力下相互贴合，带动所述柔性显示屏1紧密绕卷在一起，从而方便带动所述柔性显示屏1绕卷。所述柔性屏支撑结构100可以在柔性显示屏1展开时对柔性显示屏1进行支撑，并在柔性显示屏1绕卷时，方便柔性显示屏1紧密绕卷收缩在一起，从而提高用户体验。
本实施方式中，所述电磁体10呈锥状。作为一种可以实施的方式，所述电磁体10为梯形方台，所述电磁体10在垂于高度方向的横截面为正方形。多个所述电磁体10在所述柔性显示屏1上可以紧密排布。每一所述电磁体10具有并排于所述柔性显示屏1的第一磁极S和第二磁极N。每一所述电磁体10的第一磁极S和第二磁极N可以是沿所述柔性显示屏1长度方向并排设置，即将每一所述电磁10在所述柔性显示屏1长度方向上分第一磁极S和第二磁极N两个部分。在一种可能的情况下，所述柔性显示屏1的长度方向上，一个所述电磁体10的第一磁极S可能是与相邻所述电磁体10的第一磁极S相连接，自然地，所述电磁体10的第二磁极N与相邻所述电磁体10的第二磁极N也相连接。由于相邻两个所述电磁体10的支撑面11紧密相连，因此在所述柔性屏1呈展开状态时，相邻两个所述电磁体10的高度方向相互平行，故而相邻两个所述电磁体10的侧面12之间存在间距。而相邻两个所述电磁体10的 侧面12受两个第一磁极S或两个第二磁极N的排斥力作用而相互排斥，进而使得两个所述电磁10的侧面12始终保持存在间距，进而相邻两个所述电磁体10的支撑面11可以相平齐，进而可以对所述柔性显示屏1进行支撑。在另一种情况下，所述柔性显示屏1的长度方向上，通过所述控制器20对预设位置上的所述电磁体10的第一磁极S位置和第二磁极N位置相对调，使得一个所述电磁体10的第一磁极S与另一个所述电磁体10的第二磁极N相连接。由于相邻两个所述电磁体10的支撑面11紧密相连，因此在所述柔性屏1呈弯曲状态时，相邻两个所述电磁体10的高度方向相互呈夹角，故而相邻两个所述电磁体10的侧面12相互靠拢，进而导致相邻两个所述电磁体10的侧面12相互贴合。而相邻两个所述电磁体10的侧面12受第一磁极S和第二磁极N的吸引力作用而相互吸合，即相邻两个所述电磁体10的侧面12受吸引磁力而贴合，进而相邻两个所述电磁体10的支撑面11呈夹角，进而带动所述柔性显示屏1弯曲，并且使得所述柔性显示屏1始终保持弯曲状态。可以理解的是，该预设位置可以是所述柔性显示屏1长度方向上任意位置，即用户可以对所述柔性显示屏1的长度方向上任意位置进行弯曲。利用每一所述电磁体10的第一磁极S和第二磁极N可以是沿所述柔性显示屏1长度方向并排设置，从而所述柔性显示屏1可以在长度方向进行弯曲或展开。在其他实施方式中，所述电磁体40还可以是还可以是六棱梯形台或梯形圆台等；每一所述电磁体10的第一磁极S和第二磁极N可以是沿所述柔性显示屏1宽度方向并排设置，即所述柔性显示屏1可以在宽度方向进行弯曲或展开。当然，在其他实施方式中，所述电磁体10也可以是矩形块和锥形块相结合构成，所述电磁体10的支撑面11设置于矩形块上，所述侧面12设置锥形块上，相邻两个所述电磁体10的支撑面11之间也可以存在间距。
本实施方式中，所述控制器20可以是中央处理器，所述控制器20可以同时向所述多个电磁极10发送电信号，使所述多个电磁极10的磁极位置变换，从而可以使得所述柔性显示屏1整体弯曲；也可以是向其中部分所述电磁极10发送电信号，使部分所述电磁极10的磁极位置变换，从而可以使得所述柔性显示屏1部分弯曲。当然，在其他实施方式中，所述控制器20还可以是与移动终端的中央处理器相独立，从而提高所述柔性屏支撑结构100的控制效率。
进一步地，所述柔性显示屏支撑结构100还包括柔性面板30，所述柔性面板30贴合于所述柔性显示屏1上，所述多个电磁体10密布于所述柔性面板30与所述柔性显示屏1相背一侧。
本实施方式中，所述柔性面板30为矩形板件。所述柔性面板30呈现柔性，所述柔性面板30在外界作用力下可以任意弯曲。所述柔性面板30包括相对设置的外表面31和内表面32。在所述柔性屏支撑结构100应用于移动终端时，所述外表面31上贴合所述柔性显示屏1。所述内表面32上密布多个所述电磁体10。所述内表面32可以是粘接、或卡合、或嵌设、或者是一体设置多个所述电磁体10。利用所述柔性面板10将所述多个电磁体10与所述柔性显示屏1隔离，从而使得所述柔性显示屏1得到保护，防止所述电磁体10损伤所述柔性显示屏1，也防止所述电磁体10脱离所述柔性显示屏1。利用所述多个电磁体10附设于所述柔性面板30上，从而使得所述柔性屏支撑结构100稳固性能提高。当然，在其他实施方式中，所述第一柔性板10还可以是圆形或者其他多边形形状。
进一步地，所述多个电磁体10阵列排布于所述柔性面板30上。本实施方式中，所述多个电磁体10沿所述柔性面板30的长度方向呈纵向排列，沿所述柔性面板30的宽度方向呈横向排列。所述柔性面板30可以沿长度方向弯曲，从而使得纵向的多个电磁体10的侧面12相互靠拢，进而带动所述柔性显示屏1沿长度方向弯曲。在其他实施方式中，所述柔性面板30也可以沿宽度方向弯曲，使得宽度方向上多个所述电磁体10的侧面12相互靠拢，从而带动所述柔性显示屏1沿宽度方向弯曲。
进一步地，所述柔性面板30为弹性记忆板件。可以理解的是，在所述柔性面板30呈弯曲状态时，所述控制器20控制所述电磁体10断电，即相邻两个所述电磁体10之间撤销吸引磁力作用，在该吸引磁力消除后，所述电磁体10对所述柔性面板30的作用力消除，所述柔性面板30通过自身分子间的应力，使得自身分子链由卷曲状态变为舒展状态，从而使得所述第柔性面板30恢复至展开状态，从而可以带动所述柔性显示屏1自动恢复至展开状态。在其他实施方式中，所述柔性面板还可以由高弹性橡胶或者高弹性碳纤维等弹性材料制成。
进一步地，所述柔性屏支撑结构100还包括柔性背板40和侧板50，所述柔性背板40相对所述柔性面板30设置，并与所述柔性面板40之间形成间隙40a，所述多个电磁体10位于所述间隙40a内，所述侧板50围合于所述柔性面板30和所述柔性背板40外周侧并封闭所述间隙40a。
本实施方式中，所述柔性背板40为矩形板件。所述柔性背板40大小尺寸与所述柔性面板30相同。所述柔性背板40与所述电磁体10之间存在间距，从而使得所述柔性背板40与所述电磁体10之间形成气流通道，从而方便在所述柔性屏支撑结构100弯曲时，相邻两个所述电磁体10的侧面12之间的气流顺利流动，进而使得相邻两个所述电磁体10的侧面12可以相互靠拢。所述柔性背板40和所述柔性面板30一同弯曲，以方便所述对所述电磁体10的保护。所述柔性背板40与所述柔性面板30可以采用相同材质。
本实施方式中，所述侧板50粘接于所述柔性面板30和所述柔性背板40的周侧。所述侧板50可以是柔性薄膜，并且所述侧板50具有较好的延展性。在柔性显示屏1需要绕卷时，弯曲所述柔性面板30和所述柔性背板40，所述柔性面板30和所述柔性背板40会产生位移，导致所述侧板50也会发生形变，从而使得所述侧板50提高所述柔性屏支撑结构100的形变性能。而且多个所述电磁体10的侧面12相互靠拢，从而对相邻两个所述电磁体10之间的气体进行挤压，利用所述侧板50具有较好的形变性能，从而被挤压的气体可以流动至所述侧板50处，以使得所述侧板50鼓起。所述柔性面板30、所述柔性背板40和所述侧板50共同构成一个容置体，所述间隙40a形成该容置体的内腔，故该容置体内容置所述多个电磁体10，对所述多个电磁体10进行保护。在其他实施方式中，所述侧板采用高弹性橡胶、或者高弹性碳纤维材料。
进一步地，请参阅图3和图4，提供另一实施方式，与较优实施方式不同的是，每一所述电磁体10还具有相对所述支撑面11设置的底面13，所述底面13贴合所述柔性背板40。具体的，为了使得柔性屏支撑结构100更加稳固，从而利用所述电磁体10的底面13与所述柔性背板40相结合，避免所述柔性背板40脱离所述电磁体10，防止相邻两个所述电磁体10之间混入杂质。而且，通过所述电磁10的底面13与所述柔性背板40相贴合，所述柔性背板40在相邻两个所述电磁体10之间的区域形成可形变通道，在所述柔性面板30 和所述柔性背板40共同绕卷时，相邻两个所述电磁体10之间的气体可以被挤压至柔性背板40位于相邻两个所述电磁体10之间的可形变通道内，使得该区域被鼓起，从而可以对被挤压气体容置，防止所述柔性屏支撑结构100破损。
进一步地，请继续参阅图1和图2，在较优实施方式中，多个所述电磁体10经导电线缆相连接。本实施方式中，为方便同时对多个所述电磁体10进行通电，从而利用导电线缆对多个所述电磁体10进行串接。具体的，所述导电线缆可以包括多条横线导线和多条纵向导线，每一横向导线设有正极节点，而每一纵向导线设有负极节点，而每一正极节点和每一负极节点对应连接于所述电磁体10。每一横向导线串接于横向排列的多个所述电磁体10，每一纵向导线串接于纵向排列的多个所述电磁体10。从而在所述横向导线和所述纵向导线均通电时，每一所述电磁体40接收电压，从而所述电磁体40呈现磁性。并通过所述控制器20经该导电线缆电连接所述多个电磁体10，从而所述控制器20控制预设位置处所述电磁体10的磁极位置变换。
请参阅图5和图6，本发明还提供一种柔性显示屏模组200，所述柔性显示屏模组200包括所述柔性屏支撑结构100，所述柔性显示屏模组200还包括柔性显示屏1，所述柔性显示屏1贴合于所述柔性面板30与所述柔性背板40相背一侧。本实施方式中，所述柔性显示屏1为有机电致显示层，所述柔性显示屏1层叠于所述柔性屏支撑结构100上。具体的，所述柔性显示屏1可以是层叠于所述柔性面板30的外表面31上，并通过粘胶粘接于所述外表面31上。
请参阅图7和图8，本发明还提供另一种柔性显示屏模组300，所述柔性显示屏模组300包括柔性显示屏310，所述柔性显示屏310贴合于密布的所述多个电磁体10上。
请参阅图9，本发明还提供一种移动终端400，所述移动终端400包括所述柔性显示屏模组200。所述移动终端400还包括壳体(未图示)和固定于所述壳体内的主板(未图示)。所述柔性显示屏模组200固定于所述壳体上，并电连接所述主板。所述移动终端400可以是手机、平板电脑或者是笔记本电脑等。
本发明的柔性屏支撑结构、柔性显示屏模组及移动终端，通过在所述柔性显示屏上密布多个所述电磁体，而每一所述电磁体具有并排于所述柔性显示屏 上的第一磁极和第二磁极；同时利用所述电磁体呈梯台形，从而所述控制器控制一个所述电磁体的第一磁极与相邻一个所述电磁体的第一磁极相靠拢，可以使得相邻两个所述电磁体的侧壁受相同磁极排斥作用力下相互排斥而展开，进而所述多个电磁体带动所述柔性显示屏展开并对所述柔性显示屏进行支撑；所述控制器控制一个所述电磁体的第一磁极与相邻一个所述电磁体的第二磁极相靠拢，进而相邻两个所述电磁体的侧壁在不同磁极的吸引作用力下相互贴合，带动所述柔性显示屏紧密绕卷在一起，从而方便带动所述柔性显示屏绕卷。所述柔性屏支撑结构可以在柔性显示屏展开时对柔性显示屏进行支撑，并在柔性显示屏绕卷时，方便柔性显示屏紧密绕卷收缩在一起，从而提高用户体验。
以上是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发明的保护范围。
