现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的实施方式；相反，提供这些实施方式使得本公开将全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。图中相同的附图标记表示相同或类似的结构，因而将省略它们的详细描述。
本示例实施方式提供了一种显示装置，参照图1、图2以及图3所示的本公开显示装置一示例实施方式的结构示意图；该显示装置可以包括壳体、第一卷轴1、第二卷轴2以及柔性显示面板5；壳体具有固定部3和移动部4，所述移动部4能够相对于所述固定部3移动；第一卷轴1可转动的连接于所述固定部3；第二卷轴2可转动的连接于所述移动部4，所述第二卷轴2上设置有多个第一凸起21或第一凹槽，所述第二卷轴2与所述第一卷轴1平行设置；柔性显示面板5的一端固定于所述固定部3，相对另一端绕设于所述第一卷轴1，中部缠绕于所述第二卷轴2，所述柔性显示面板5上设置有多个与所述第一凸起21配合的第二凹槽54，或设置有多个与所述第一凹槽配合的第二凸起。
在本示例实施方式中，壳体设置为长方体的形状。壳体可以包括固定部3和移动部4，移动部4能够相对于固定部3移动。
固定部3可以包括固定外壳31、两个第一空心杆32和两个第二空心杆33。固定外壳31设置为长方体的形状，固定外壳31具有开口部，固定外壳31可以包括顶壁311、底壁312、第一侧壁313和两个第二侧壁314，顶壁311、底壁312、第一侧壁313和两个第二侧壁314均可以是长方形的板，由于设置三个侧壁，即一个第一侧壁313和两个第二侧壁314，三个侧壁对应连接于顶壁311和底壁312的三个边沿，使顶壁311和底壁312的四个边沿中的一个边沿没有连接继而形成开口部。具体地，第一侧壁313连接于顶壁311和底壁312的远离移动部4的一侧边沿，两个第二侧壁314对称连接于顶壁311、底壁312和第一侧壁313。第一侧壁313与第一卷轴1平行设置，两个第二侧壁314与第一卷轴1垂直设置。
两个第一空心杆32和两个第二空心杆33对应位于固定外壳31的四个角部，即位于第一侧壁313的四个角部。两个第一空心杆32和两个第二空心杆33都相互平行设置，两个第一空心杆32和两个第二空心杆33的一端固定连接于第一侧壁313的内壁面，两个第一空心杆32和两个第二空心杆33另一端通过开口部突出于固定外壳31。两个第一 空心杆32上下对称设置，两个第二空心杆33也上下对称设置，第一空心杆32与第二空心杆33对称设于第一卷轴1的相对两端面。
在本示例实施方式中，在靠近顶壁311的第一空心杆32和第二空心杆33之间连接有支撑板，顶壁311与靠近顶壁311的第一空心杆32和第二空心杆33之间设置有间隔空间，使顶壁311与支撑板之间也具有间隔空间。
移动部4可以包括两个活动支架，两个活动支架的结构完全相同，且两个活动支架对称设置，两个活动支架设于第二卷轴2的两端面。活动支架可以包括两个活动杆41和一个连接板42，两个活动杆41平行设置，连接板42连接于两个活动杆41之间，且连接板42位于活动杆41的远离固定部3的一端。两个活动杆41对应插入第一卷轴1的同一端面两个第一空心杆32内，另外一个活动支架的两个活动杆41对应插入两个第二空心杆33内，活动杆41可以沿第一空心杆32和第二空心杆33运动，从而带动连接板42也沿第一空心杆32和第二空心杆33运动，以使整个移动部4能够相对于固定部3移动。
在本示例实施方式中，在靠近底壁312的第一空心杆32和第二空心杆33之间连接有第一卷轴1。具体地，在第一空心杆32和第二空心杆33的远离底壁312的一侧均设置有安装壳6，安装壳6上设置有圆形通孔，第一卷轴1的端部插入圆形通孔内。在安装壳6内设置有扭簧，扭簧为恒定扭簧(图中未示出)，恒定扭簧的一端与安装壳6的内侧壁固定连接，恒定扭簧的另一端与第一卷轴1固定连接，恒定扭簧能够为第一卷轴1提供恒定的扭转力。恒定扭簧可以为第一卷轴1提供回转力，使第一卷轴1可以相对于固定部3进行转动。
另外，固定部3和移动部4的结构不限于上述说明，例如，固定部3可以包括一个侧壁，在侧壁上可以垂直设置四个导轨。移动部4可以在活动杆41上设置与导轨配合的滑块。还可以将固定部的第一空心杆32和第二空心杆33设置为实心杆，而移动部4的活动杆41设置为空心杆，固定部的实心杆插入移动部4空心杆内。
还可以在固定部3和移动部4之间设置锁紧机构，锁紧机构可以锁定固定部3和移动部4，避免移动部4的移动。锁紧机构可以包括设置在第一空心杆32或第二空心杆33上的多个过孔，多个过孔沿第一空心杆32或第二空心杆33的长度方向排布；以及设置在活动杆41上的弹簧和连接在弹簧上的卡柱，弹簧的中心轴线与活动杆41的中心轴线垂直。需要使活动杆41能够移动时，可以施加较大的拉力或推力使卡柱受挤压下移，使活动杆41可移动切换至不同的卡点位置；需要使活动杆41不能够移动时，可以使卡柱卡在通孔内。
在本示例实施方式中，在两个活动支架的两个连接板42之间连接有第二卷轴2。具体地，第二卷轴2的两端部通过轴承连接在两个连接板42的中部位置，使第二卷轴2可 以相对于活动支架进行转动。
在本示例实施方式中，参照图5所示，柔性显示面板5可以包括柔性屏51和支撑膜组；支撑膜组设于柔性屏51的与显示面相对的一面，在支撑膜组的远离柔性屏51的一面设置有第二凹槽54。第二凹槽54沿第一卷轴1的轴向设置，即第二凹槽54的长度方向与第一卷轴1的轴向一致。
具体地，支撑膜组可以包括第一支撑膜52和第二支撑膜53；第一支撑膜52设于柔性屏51的与显示面相对的一面，第二支撑膜53设于第一支撑膜52的远离柔性屏51的一面。第一支撑膜52的材质可以为金属或塑料，第二支撑膜53的材质可以为硅胶，还可以是橡胶。第一支撑膜52的厚度大约介于50um～200um之间，第二支撑膜53的厚度大约介于0.3mm～2mm之间。第二支撑膜53可以包括多个膜条55，膜条55的长度方向与第二卷轴2的轴向一致，相邻两个膜条55之间形成“V”字形的第二凹槽54，即膜条55的与第二卷轴2的轴向垂直的截面形状可以为等腰梯形，等腰梯形的长底边与第一支撑膜52连接，等腰梯形的短底边位于远离第一支撑膜52的一侧，相邻两个膜条55的侧壁就形成第二凹槽54的槽壁。当然，在本公开的其他示例实施方式中，第二凹槽54的与第二卷轴2的轴向垂直的截面形状可以是等腰梯形、“U”字形等开口部大于底部的形状，便于第一凸起21嵌入第二凹槽54内；可以在膜条55上不设置第二凹槽54，而是设置第二凸起，第二凸起沿第一卷轴1的轴向设置，即第二凸起的长度方向与第一卷轴1的轴向一致。
在本公开的另外一些示例实施方式中，支撑膜组可以仅包括第一支撑膜52，即可以不设置第二支撑膜53。第一支撑膜52的材质可以为金属或塑料，在第一支撑膜52的远离柔性屏51的一侧可以设置第二凹槽54或第二凸起，第二凹槽54的与第二卷轴2的轴向垂直的截面形状也可以是“V”字形、“U”字形、等腰梯形等开口部大于底部的形状。
需要说明的是，第二凹槽54可以贯穿整个支撑膜组，也可以仅占据支撑膜组的部分长度，即第二凹槽54的长度等于或小于支撑膜组的长度。多个第二凹槽54可以并排设置，也可以错位设置。
在本示例实施方式中，参照图4所示，在第二卷轴2上设置有第一凸起21，第一凸起21沿第二卷轴2的轴向延伸，即第一凸起21的长度方向与第二卷轴2的轴向一致。第一凸起21的与第二卷轴2的轴向垂直的截面形状也可以是“V”字形。第一凸起21的高度可以小于或等于第二凹槽54的深度，第一凸起21的宽度可以小于或等于第二凹槽54的宽度，第一凸起21的长度小于或等于第二凹槽54的长度，使第一凸起21能够与第二凹槽54配合，即第一凸起21能够嵌入第二凹槽54内。当然，在本公开的其他示例实施方式中，第一凸起21的与第二卷轴2的轴向垂直的截面形状可以是与第二凹槽 54相适应的等腰梯形、“U”字形等。
在第二凹槽54贯穿整个支撑膜组的情况下，第一凸起21也能够延伸整个第二卷轴2，也可以仅占据第二卷轴2的部分长度。多个第一凸起21可以并排设置，也可以错位设置，只要与个第二凹槽54相适配即可，使相邻两个第二凹槽54之间的间距与相邻两个第一凸起21之间的间距相同。
另外，第一凸起21、第一凹槽、第二凸起和第二凹槽54的形状也不限于上述说明，例如，第一凸起21或第一凹槽的与第二卷轴的轴向平行的截面形状为矩形、椭圆形、圆形、平行四边形等等，第二凸起或第二凹槽54的与第二卷轴的轴向平行的截面形状对应为矩形、椭圆形、圆形、平行四边形等等。
在本示例实施方式中，请继续参照图5所示，第一支撑膜52具有相对设置的第一端和第二端，第二支撑膜53也具有相对设置的第一端和第二端。第一支撑膜52的第一端和第二端对应突出于第二支撑膜53的第一端和第二端，即第一支撑膜52的长度大于第二支撑膜53的长度，且第二支撑膜53位于第一支撑膜52的中部位置。第一支撑膜52的第一端固定于固定部3的固定外壳31的上表面，第一支撑膜52的第二端绕设于第一卷轴1，即第二支撑膜53没有与固定部3的固定外壳31连接，第二支撑膜53也没有绕设于第一卷轴1上。第二支撑膜53的主要作用是与第二卷轴2卷轴配合，避免在该显示装置展开时第二卷轴2打滑、出现空转，而使柔性显示面板5局部受力不均导致损坏。因此，将第二支撑膜53的长度设置的较短，可以节省物料和人力资源。
在本示例实施方式中，柔性屏51也具有相对设置的第一端和第二端。柔性屏51的长度也小于第一支撑膜52的长度，且柔性屏51的第一端与第一支撑膜52的第一端对齐，第一支撑膜52的第二端突出于柔性屏51的第二端。使柔性屏51的第一端通过第一支撑膜52固定在固定部3的固定外壳31的上表面，柔性屏51的第二端没有绕设于第一卷轴1上，柔性屏51仅绕设在第二卷轴2上。该显示装置在使用时必然有一部分柔性显示面板5需要绕设在第一卷轴1上，柔性屏51绕设在第一卷轴1上时无法进行显示，是无效部分，这样可以使柔性屏51的长度制作的较短，避免无效部分的长度，从而节省物料和人力资源、降低成本。
在本示例实施方式中，该显示装置还可以包括辅助支撑件7，辅助支撑件7的一端可以连接于移动部，且靠近第二卷轴2，相对的另一端搭设于固定部，且位于柔性显示面板的远离显示面的一侧以支撑柔性显示面板。辅助支撑件7可以包括多个支撑条71，多个支撑条71的远离柔性显示面板的一侧可以通过胶带连接，支撑条71沿第二卷轴2的轴向延伸，即多个支撑条71相互平行设置，支撑条71的长度方向与第二卷轴2的轴向一致。辅助支撑件7的一端连接于活动杆4，辅助支撑件7的相对另一端插入顶壁311 与支撑板之间的间隔空间内，在该显示装置展开时，活动杆4会将辅助支撑件7拉出，辅助支撑件7为柔性显示面板5提供支撑，在该显示装置收卷时，辅助支撑件7会插入顶壁311与支撑板之间的间隔空间内。在本公开的其他示例实施方式中，辅助支撑件7的一端可以连接于第二卷轴2，该显示装置展开时，会有部分辅助支撑件7缠绕在第二卷轴2上。当然，辅助支撑件7也可以设置为刚性支撑板。
该显示装置使用时，用户向相反的方向拉动固定部3和移动部4，移动部4的活动杆41从固定部3的第一空心杆32和第二空心杆33中拉出，柔性显示面板5和辅助支撑件7也被拉出，在这个过程中柔性显示面板5带动第一卷轴1和第二卷轴2顺时针旋转，使柔性显示面板5能够顺利展开，第一卷轴1会带动两个恒定扭簧进行旋转，使恒定扭簧具有恒定的扭转力。柔性显示面板5展开到预设位置使用完成进行收卷时，用户放开移动部4，在恒定扭簧的扭转力的作用下，第一卷轴1进行逆时针旋转，将柔性显示面板5的第二支撑膜53缠绕在第一卷轴1上，同时，柔性显示面板5会带动第一卷轴1进行逆时针旋转，直至完成收卷。在该显示装置展开或收卷时，由于柔性显示面板5上的第二凹槽54或第二凸起与第二卷轴2上的第一凸起21或第一凹槽的配合，柔性显示面板5能够带动第二卷轴2转动，避免第二卷轴2空转造成的柔性显示面板5局部受力不均导致的损坏。
