具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
下面结合附图和具体实施例对本申请做进一步的说明：
本申请实施例提供一种可滑动的柔性显示设备，请参考图1至图11，所述柔性显示设备包括第一支撑主体1、第二支撑主体2、联动机构3和柔性显示屏4。见图2所示，所述第一支撑主体1包括一第一后壳10和一第一支撑板30。见图3所示，所述第二支撑主体2包括一第二后壳20、一第二支撑板40、侧壁50。见图4所示，所述联动机构3包括丝杆组60、滚筒70和一屏固定板80。
本实施例中，第一支撑板30固定设置在所述第一后壳10上。所述第一支撑板30的底部具有至少一具有孔结构的第一丝母结构34。
本实施例中，所述第二后壳20的两侧分别固定设置一侧壁50。所述侧壁50为一长形，所述侧壁50的两端各具有一支架结构52。在所述侧壁50上，其中一端的所述支架结构52的外侧还设置有一壁轴54。所述侧壁50设置在所述第二后壳20的两侧。并且两个侧壁50相对设置。所述第二支撑板40固定设置在所述侧壁50上。
本实施例中，所述侧壁50上还连接有一滑动结构56；所述第一支撑板30的两侧分别通过所述滑动结构56与所述侧壁50滑动连接，使得所述第一支撑板30与所述侧壁50之间可相互滑动。具体的，所述滑动结构56可以位于所述支架结构52的上方，且与所述丝杆组60平行。此处的滑动方向与所述滚筒70的自转轴相互垂直。例如，所述滑动结构56可以是滑轨。
本实施例中，每一侧壁50上固定放置有所述丝杆组60。所述丝杆组60包含平行设置的第一丝杆60a和第二丝杆60b，所述第一丝杆60a和所述第二丝杆60b能够自身转动且彼此连动。所述第一丝杆60a和所述第二丝杆60b的表面具有旋转螺纹结构。具体地，所述丝杆组60中，所述第一丝杆60a和所述第二丝杆60b至少有一端连接一联动齿轮110，以使所述第一丝杆60a和相邻的所述第二丝杆60b保持联动。例如，所述联动齿轮110可以放置于所述支架结构52内。
所述滚筒70夹持设置在两个侧壁50之间，且所述滚筒70能够自身转动。并且所述滚筒70的位置靠近所述第二后壳20的弧形端22。具体的，所述滚筒70的两端分别具有一壁轴孔72。所述壁轴孔72的尺寸与所述壁轴54适配，可以将所述壁轴孔72套在所述壁轴54上。这样的话，所述滚筒70可以夹持放置在两个所述侧壁50之间，并且所述滚筒70能够自转运动。
更进一步限定，所述丝杆组60的自转轴与所述滚筒70的自转轴相互垂直。
具体地，所述丝杆60a可从所述第一丝母结构34内穿过，并且所述第一丝母结构34的内表面具有与所述第一丝杆60a的旋转螺纹结构相适配的螺纹结构，以使所述第一支撑板30通过所述第一丝母结构34与所述丝杆组60中的所述第一丝杆60a联动连接。另外，所述屏固定板80的一侧设有与所述第一丝母结构34的结构基本相同的第二丝母结构82，并且所述第二丝母结构82的内表面具有与所述第二丝杆60b的旋转螺纹结构相适配的螺纹结构，以使所述屏固定板80通过所述第二丝母结构82与所述第二丝杆60b联动连接。
进一步地，所述丝杆组60中的所述第一丝杆60a和所述第二丝杆60b的旋转螺纹结构的方向相反，或者，所述丝杆组60中的所述第一丝杆60a和所述第二丝杆60b的旋转运动方向相反；以实现所述第一支撑板30和所述屏固定板80的滑移运动的方向相反。
本实施例中，所述柔性显示屏4放置在所述第一支撑板30和所述第二支撑板40之上，并且所述柔性显示屏4的一端固定在所述第一支撑板30的圆弧端32，另一端绕过所述滚筒70翻转至所述丝杆组60下方并固定在所述屏固定板80的表面上。
本实施例中，所述屏固定板80与所述丝杆组60中的所述第二丝杆60b联动连接。并且，所述屏固定板80与所述第一支撑板30和/或所述第二支撑板40平行设置在所述丝杆组60的两侧。
本实施例中，所述屏固定板80相对于所述第二支撑主体2的移动速度与所述第二支撑主体2相对于所述第一支撑主体1的移动速度相同。换句话说，所述屏固定板80相对于所述第二支撑板40的移动速度与所述第二支撑板40相对于所述第一支撑板30的移动速度相同。这样可避免对所述柔性显示屏4发生力的拉扯而破坏所述柔性显示屏4。
本实施例提供的可滑动的柔性显示设备，所述第一支撑主体1和所述第二支撑主体2之间可沿直线进行滑移运动。具体地，请参考图5和图6，其中图5为所述柔性显示设备收缩状态的视图，所述第一支撑主体1和所述第二支撑主体2处于最靠近的状态，其中，所述第二支撑主体2大部分位于所述第一支撑主体1的内部空间。当所述第一支撑主体1和所述第二支撑主体2滑移至较大距离时，即显示为图6所示的柔性显示设备展开状态。
具体地，在所述柔性显示设备中，所述第一后壳10和所述第二后壳20在接触面上分别设置有相互匹配的滑动结构，以使所述第一后壳10和所述第二后壳20之间滑动连接。所述侧壁50的外表面与所述第一后壳10两侧的内表面上分别设置有相互适配的滑动结构，以使所述侧壁50与所述第一后壳10之间滑动连接。所述第一支撑板30和所述第二支撑板40相互滑动连接。例如，所述第二支撑板40的部分结构能够嵌入放置在所述第一支撑板30的上表面，且所述第二支撑板40与所述第一支撑板30能够相对滑动运动。并且，所述第二支撑板40与所述第一支撑板30的上表面高度始终相同，以共同支撑所述柔性显示屏4。
请参考图7和图8，可以看出，随着所述第一支撑主体1远离所述第二支撑主体2滑移，所述第二支撑主体2原本位于所述柔性显示设备内部空间的部分随着联动运动而展现出来。同时，从图中还可以看出，所述柔性显示屏4的一端连接的屏固定板80，从收缩状态下的远离滚筒70的位置滑移至展开状态下的靠近滚筒70的位置，进而实现将柔性显示屏4从内部展开，实现了所述柔性显示设备的屏幕扩大。相反地，从展开状态滑移至收缩状态，可将展现在外部的部分柔性显示屏4收缩至所述柔性显示设备的内部空间中，以实现所述柔性显示设备的屏幕缩小，减少所述柔性显示设备的占用空间。
进一步地，请参考图9和图10，去除了部分后壳，可以更清晰地看出所述柔性显示设备从收缩状态滑移至展开状态时的内部结构的位置关系。所述第一支撑板30和所述屏固定板80分别与所述丝杆组60中的所述第一丝杆60a和所述第二丝杆60b连接。具体地，所述第一支撑板30与所述丝杆组60的所述第一丝杆60a联动连接，所述屏固定板80与所述丝杆组60的所述第二丝杆60b联动连接。通过所述丝杆组60，使得所述第一支撑板30和所述屏固定板80的运动方向相反。例如，请参考图11，图11是图10中A处的放大图，所述第一丝杆60a和所述第二丝杆60b表面的旋转螺纹结构相反，并且通过所述联动齿轮110使所述第一丝杆60a和所述第二丝杆60b的自转方向一致，进而，可以实现所述第一支撑板30和所述屏固定板80向相反方向的联动滑移。由于所述柔性显示屏4的一端固定在所述第一支撑板30的圆弧端32，另一端绕过所述滚筒70翻转至所述丝杆组60下方并固定在所述屏固定板80上；因此，可以想象，当所述屏固定板80远离所述第一支撑板30运动时，使原先藏于机壳内部的柔性显示屏4拉出至机构上表面，实现了所述柔性显示屏4的展开，使所述显示设备的尺寸增加；当所述屏固定板80靠近所述第一支撑板30运动时，使展开的柔性显示屏4收缩至机构内部，实现了所述柔性显示屏4的收缩，使所述显示设备的尺寸缩小直至最小尺寸。
同理，在一些实施例中，可以通过调节所述丝杆组60为：所述第一丝杆60a和所述第二丝杆60b的自转方向相反、表面的旋转螺纹结构相同，这样同样可以实现所述第一支撑板30和所述屏固定板80向相反方向的联动滑移。
在一些实施例中，所述联动齿轮110可与电机连接。所述电机带动所述联动齿轮110的转动，使得所述丝杆组60中的所述第一丝杆60a和所述第二丝杆60b自动地进行自转。然后，所述丝杆组60联动所述第一支撑板30和所述屏固定板80向相反方向的联动滑移，进而实现所述柔性显示屏4的展开或收缩。所述柔性显示设备的展开与收缩可以通过电驱使自动切换，代替了外力的推动驱使，更加便于实际应用。
以上对本申请实施例的技术方案进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
