 背景技术
随着显示技术的发展，用户对显示装置也提出了各种不同的需求，为了满足不同的使用需求，各种具有不同特性的显示产品也随之应用而生，其中，消费者现在不仅仅追求简单的大屏幕，更是希望能够在实现大屏幕的同时更好的满足便捷性和便携性的要求。
有机发光二极管（Organic Light-Emitting Diode，OLED）显示装置以其可弯曲、可挠曲受到广泛关注，通过将OLED显示装置进行折叠或卷起可使较大尺寸屏幕所占用的空间减小，使其更加的便携，因此可折叠和可卷曲显示装置为OLED显示装置的主要研究方向之一。
目前，可卷曲显示装置中，可将柔性屏拉出进行大尺寸显示或将柔性屏收纳进行小尺寸显示，但是，在柔性屏进行拉伸或收纳过程中容易出现偏斜或卡顿的现象。

本申请实施例提供一种柔性显示装置，请参照图1，柔性显示装置包括壳体10、拉伸组件20、柔性屏30以及传动组件40。
其中，拉伸组件20包括设置于壳体10上的第一支撑部21、与第一支撑部21可移动连接的第二支撑部22、以及设置于第二支撑部22中的旋转收纳部23。
柔性屏30设置于拉伸组件20上，且柔性屏30的一端与第一支撑部21连接，柔性屏30的另一端与旋转收纳部23连接。
传动组件40设置于第二支撑部22上，且传动组件40的一端可移动地连接于壳体10，传动组件的40的另一端与旋转收纳部23传动连接，进一步地，传动组件40在相对于壳体10进行移动的过程中，用于带动第二支撑部22相对于第一支撑部21移动，并带动旋转收纳部23转动，以使得柔性显示装置在第一状态与第二状态之间切换，其中，第一状态下柔性屏30位于第一支撑部21和第二支撑部22上的面积小于第二状态下柔性屏30位于第一支撑部21和第二支撑部22上的面积。
在实施应用过程中，本申请实施例中将柔性屏30的两端分别连接于第一支撑部21与旋转收纳部23，并通过使得第一支撑部21与第二支撑部22之间相对移动，以使得柔性屏30铺展于第一支撑部21与第二支撑部22上面积增大或减小，以实现大尺寸显示和小尺寸显示之间的切换，同时，本申请实施例通过设置于传动组件40连接于壳体10与旋转收纳部23之间，在传动组件40现对于壳体10进行移动过程中，在带动第一支撑部21相对于第二支撑部22进行移动的同时，还可带动旋转收纳部23进行转动，且进而可使得柔性屏30旋转收纳于旋转收纳部23上，或旋转拉伸至第一支撑部21与第二支撑部22上以用于显示。即本申请实施例通过设置传动组件40以实现第一支撑部21与第二支撑部22的相对移动以及旋转收纳部23的转动二者同步进行，提高了柔性显示装置在状态切换过程中的受力均一性和同步性，防止了柔性屏30因传动力不均一而受到损伤，因此，本申请实施例提供的柔性显示装置的可靠性，实现了柔性显示装置在小尺寸便携状态与大尺寸显示状态之间快速灵活的转换。
具体地，请结合图1、图2、图3、图4以及图5，柔性显示装置包括壳体10、拉伸组件20、柔性屏30以及传动组件40。
壳体10包括外框11以及设置于外框远离柔性显示装置的显示面一侧的后板12。
拉伸组件20包括可移动连接于壳体10上的第一支撑部21、与第一支撑部21可移动连接的第二支撑部22以及设置于第二支撑部22中的旋转收纳部23。其中，第一支撑部21可现对于壳体10沿第一方向X进行滑动，且滑动距离较小，且壳体10与第一支撑部21之间连接有弹性件112，以使得第一支撑部21相对于壳体10沿第一方向X进行滑动过程中，具有一定的预紧力。
进一步地，第一支撑部21朝向柔性显示装置显示面的一侧包括多个第一支撑板211，第二支撑部22朝向柔性显示装置显示面的一侧包括多个第二支撑板221，多个第一支撑板211与多个第二支撑板221之间可相对移动，可沿第一方向X进行相对移动。且柔性屏30铺设于多个第一支撑板211与多个第二支撑板221上，以用于显示。
其中，多个第一支撑板211与多个第二支撑板221相交错设置，同时，多个第一支撑板211与多个第二支撑板221朝向柔性显示装置显示面的一侧共面设置，且任意相邻两个第一支撑板211之间的距离等于任一第二支撑板221的宽度，以为柔性屏30提供平整的支撑。
第二支撑部22还包括设置于第二支撑部22远离第一支撑部21一端的端壳222，旋转收纳部23设置于端壳222内，且旋转收纳部23的两端与端壳222的相对两侧转动连接。
需要说明的是，柔性屏30的一端固定连接于第一支撑部21远离端壳222的一侧，柔性屏30的另一端固定连接于旋转收纳部23上，且可随旋转收纳部23的转动，卷曲收纳于旋转收纳部23上。
拉伸组件20包括设置于第二支撑部22上并可移动地连接于壳体的至少一第一传动件41、设置于第二支撑部22上并可移动连接于壳体的至少一第二传动件42，其中，每一第一传动件41的一端与对应的一第二传动件传动连接，每一第一传动件41的另一端与旋转收纳部23传动连接。
当第二传动件42在相对于壳体10沿第一方向X进行移动过程中，将会带动与其传动连接的第一传动件41进行转动并相对于壳体10沿第一方向X进行移动，且第一传动件41进行转动过程中，将会带动与其传动连接的旋转收纳部23进行转动，且第一传动件41与第二传动件42在相对于壳体10沿第一方向X进行移动过程中，将会使得第二支撑部22与第一支撑部21之间发生相对移动。
需要说明的是，当第一传动件41与第二传动件42相对于壳体10沿第一方向X的正向进行移动时，第一支撑板211与第二支撑板221之间相互远离，且柔性屏30的一端连接于第一支撑部21并受到朝第一方向X的反向拉力，柔性屏30的另一端连接于旋转收纳部23并由旋转收纳部23将卷曲于其上的柔性屏30卷出，以铺展于多个第一支撑板211与多个第二支撑板221上，以实现大尺寸显示，当第一传动件41与第二传动件42相对于壳体10沿第一方向X的正向移动到预设距离时，柔性屏30铺展于多个第一支撑板211与多个第二支撑板221上的面积达到最大，为第二状态，即大尺寸显示状态。
当第一传动件41与第二传动件42相对于壳体10沿第一方向X的反向进行移动时，第一支撑板211与第二支撑板221之间相互靠近，且柔性屏30的一端连接于第一支撑部21并受到朝第一方向X的正向拉力，柔性屏30的另一端连接于旋转收纳部23并由旋转收纳部23将铺展于多个第一支撑板211与多个第二支撑板221上的部分柔性屏30卷曲收纳，以实现小尺寸显示，当第一传动件41与第二传动件42相对于壳体10沿第一方向X的反向移动到预设距离时，柔性屏30铺展于多个第一支撑板211与多个第二支撑板221上的面积达到最小，为第一状态，即小尺寸显示状态。
需要说明的是，柔性显示装置处于第一状态与第二状态下，弹性件112均处于拉伸状态，以使得第一支撑部21与壳体10之间时刻保持预紧力，即使得柔性屏30时刻受到沿第一方向X的反向的拉力，以使得柔性屏30处于拉紧状态，进而不会在多个第一支撑板211与多个第二支撑板221上铺展时出现起伏的状态，提高了显示效果。且第二状态下弹性件112具有弹力大于第一状态下弹性件112具有的弹力。
优选的，传动组件40包括设置于第二支撑部22相对两侧的两第一传动件41、设置于所述第二支撑部22相对两侧的两第二传动件42，每一第一传动件41的一端与对应的一第二传动件42传动连接，另一端与旋转收纳部23传动连接。即本申请实施例将第一传动件41与第二传动件42设置于柔性显示装置的相对两侧，同时位于柔性屏30的相对两侧，进而在对柔性屏30进而拉伸和收纳过程中，对柔性屏30产生的拉力更加均一，提高了柔性显示装置的良品率。
在本申请实施例中，第一传动件41包括丝杆结构、以及分别设置于丝杆结构两端的第一传动齿轮412与第二传动齿轮413，且丝杆结构包括丝杆411以及套设于丝杆411上的套件414。其中，第一传动齿轮412与第二传动齿轮413均为锥齿轮。
可选的，本申请实施例提供的丝杆结构为滚珠丝杆。
第二传动件42包括第一转轴421、设置于第一转轴421两端的第三传动齿轮422与第四传动齿轮423。其中，第三传动齿轮422为直齿轮，第四传动齿轮423为锥齿轮。
旋转收纳部23包括第二转轴231以及设置于第二转轴231两端的第五传动齿轮232。其中，第五传动齿轮232为锥齿轮。
外框11上设置有齿条111。
本申请实施例中的第一传动件41与第二传动件42皆设置于第二支撑部22的相对两侧，且本申请实施例以其中一侧的连接和传动结构为例进行说明，另一侧与该侧相同，在此不再赘述。
具体地，第一转轴421设置于第二支撑部22上靠近外框11的一侧，并可相对于第二支撑部22进行转动，第三传动齿轮422连接于第一转轴421靠近外框11的一端，第四传动齿轮423连接于第一转轴421的另一端。其中，第三传动齿轮422与齿条111相啮合，第二传动齿轮413与第四传动齿轮423相啮合，第一传动齿轮412与第五传动齿轮232相啮合，外框11上还设置有开口113，且套件414设置于开口113处，其中，丝杆411为螺杆，而套件414包括与螺杆相匹配的螺母，进而当套件414设置于开口113处时，由于滚珠丝杆可将回转运动转换为直线反复运动的机理，在丝杆411相对于套件414进行转动过程中，丝杆411还相对于套件414沿第一方向X进行往复运动。且套件414设置于外框11上，即设置于壳体10上，即丝杆411进行转动过程中，还相对于壳体10沿第一方向X进行移动。
承上，当柔性显示装置由第一状态向第二状态切换过程中，第三传动齿轮422相对于齿条111沿第一方向X的正向进行旋转移动，同时带动第二支撑部22沿第一方向X的正向进行移动，且带动第二支撑部22相对于第一支撑部21之间进行相对滑动，使得第二支撑部22与第一支撑部21之间相互远离，使得多个第一支撑板211与多个第二支撑板221朝向柔性显示装置显示面一侧的支撑面积变大。同时，与第三传动齿轮422同轴连接的第四传动齿轮423也进行转动，第四传动齿轮423带动第二传动齿轮413进行转动，第二传动齿轮413带动丝杆411进行转动，且丝杆411进行转动过程中，将相对于壳体10沿第一方向X的正向进行移动，同时丝杆411带动第一传动齿轮412进行转动，且第一传动齿轮412带动第五传动齿轮232进行转动，第五传动齿轮232带动第二转轴231进行转动，使得卷曲于第二转轴231上的部分柔性屏30被拉伸出来，以铺展于多个第一支撑板211与多个第二支撑板221上，以实现大尺寸显示。
当柔性显示装置由第二状态向第一状态切换过程中，第三传动齿轮422相对于齿条111沿第一方向X的反向进行旋转移动，同时带动第二支撑部22沿第一方向X的反向进行移动，且带动第二支撑部22相对于第一支撑部21之间进行相对滑动，使得第二支撑部22与第一支撑部21之间相互靠近，使得多个第一支撑板211与多个第二支撑板221朝向柔性显示装置显示面一侧的支撑面积变小。同时，与第三传动齿轮422同轴连接的第四传动齿轮423也进行转动，第四传动齿轮423带动第二传动齿轮413进行转动，第二传动齿轮413带动丝杆411进行转动，且丝杆411进行转动过程中，将相对于壳体10沿第一方向X的反向进行移动，同时丝杆411带动第一传动齿轮412进行转动，且第一传动齿轮412带动第五传动齿轮232进行转动，第五传动齿轮232带动第二转轴231进行转动，使得卷曲于第二转轴231上的部分柔性屏30被卷曲收纳，以使得部分铺展于多个第一支撑板211与多个第二支撑板221上的柔性屏30被卷曲收纳，以实现小尺寸显示。
需要说明的是，在柔性显示装置由第二状态向第一状态切换过程中，柔性屏30的卷曲速度随第二转轴231上卷曲的柔性屏30的圈数的增加而增大，且大于第二支撑部22沿第一方向X的反向进行移动的速度，当第二转轴231上卷曲的柔性屏30的圈数大于1时，第二转轴231旋转过程中的直径变大，由于第二转轴231转动的角速度以及第二支撑部22沿第一方向X的反向进行移动的速度皆不变，则柔性屏30卷曲的线速度随直径的变大而变大，进而柔性屏30卷曲的速度将大于第二支撑部22沿第一方向X的反向进行移动的速度，进而会对柔性屏30产生向第一方向X的正向的拉力，但同时，弹性件112对柔性屏30沿第一方向X的反向的拉力在由第二状态向第一状态切换过程中逐渐降低，进而可以使得柔性屏30受到沿第一方向X的正向与反向的总拉力大小保持均一，进而在使得柔性屏30在拉伸和收纳过程中保持拉紧状态的同时，其受到的拉力大小也不会发生较大变化，避免了柔性屏30受到损坏。
在本申请的一种实施例中，可通过电力驱动，使得第二支撑部22相对于壳体10沿第一方向X进行移动。具体地，柔性显示装置还包括设置于壳体10内的电机（图中并未示出），且电机设置于第二支撑部22上，电机的输出端连接于第四传动齿轮423，并驱动第四传动齿轮423进行转动，同时可带动第三传动齿轮422与丝杆411进行转动，进而实现上述第一状态与第二状态之间的切换过程。
需要说明的是，电机还可以设置于端壳222中，且电机的输出端连接于第五传动齿轮232，以使得第五传动齿轮232转动，进而带动丝杆411进行旋转，以实现上述第一状态与第二状态支架内的切换过程。
在本申请的另一种实施例中，可通过沿第一方向X的正向和反向同时拉动端壳222与外框11，使得第三传动齿轮422在齿条111上进行旋转移动，进而带动丝杆411进行转动，以实现上述第一状态与第二状态之间的切换过程。
综上所述，本申请实施例提供的柔性显示装置，通过在第一支撑部21与第二支撑部22的相对两侧设置丝杆411与齿轮组的相配合的传动组件40，使得柔性屏30的两侧在拉伸以及收纳过程中均为同步进行，且受力均一，避免了柔性屏30因受力不均而受到损伤，提高了柔性显示装置的良品率。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
