可卷曲显示装置 技术领域
本申请涉及显示领域，具体涉及一种可卷曲显示装置。
 背景技术
随着柔性显示器的市场需求增大，目前对于各种柔性显示装置的研究和开发越来越受到重视，例如已经在开发使用的可卷曲的显示装置，可以使显示装置在平板模式和手机模式之间切换，通过一系列的铰链、支柱等装置，实现柔性屏的展开与收缩。
目前的可卷曲显示装置一般使用单转轴单方向伸缩的卷曲方案，该可卷曲显示装置主要包括卷轴和柔性屏，卷轴内设有转轴，卷轴开设有开口，柔性屏收卷在转轴上，柔性屏的一端连接于转轴，另一端可由开口伸缩。然而，该可卷曲显示装置在使用过程中，当柔性屏的一部分拉伸时，由于收卷在转轴上的柔性屏的折叠半径过小，且转轴与开口的相对位置固定，使得柔性屏与开口或卷轴内壁产生挤压，进而导致柔性屏在收卷过程中产生刮伤等问题。
因此，亟需提供一种可卷曲显示装置，以解决上述技术问题。

现结合具体实施例对本申请的技术方案进行描述。

具体地，所述固定构件121包括第一固定盘1211以及第二固定盘1212，所述连接构件122包括位于所述固定构件121一侧的第一连接板1221以及位于所述固定构件121另一侧的第二连接板1222；

其中，当所述柔性显示面板40处于完全收紧状态时，在平行于所述第一转轴1121或者所述第二转轴1122的方向上，所述第一旋转盘1111在所述第一固定盘1211上的正投影与所述第一固定盘1211重合，所述第二旋转盘1112在所述第二固定盘1212上的正投影与所述第二固定盘1212重合。
请参阅图2，在本申请实施例中，所述旋转组件11还包括转轴构件112，所述转轴构件112用于卷曲所述柔性显示面板40，所述转轴构件112设置于所述第一旋转盘1111与所述第二旋转盘1112之间；
其中，所述第二旋转盘1112通过所述转轴构件112与所述第一旋转盘1111同步转动。
在本申请实施例中，所述转轴构件112包括第一转轴1121以及第二转轴1122，所述第二转轴1122与所述第一转轴1121之间形成有间隙，所述间隙用于提供被卷曲的部分所述柔性显示面板40的放置空间。
具体地，所述第一转轴1121的第一端与所述第一旋转盘1111转动连接，所述第一转轴1121的第二端与所述第二旋转盘1112转动连接；所述第二转轴1122的第一端与所述第一旋转盘1111转动连接，所述第二转轴1122的第二端与所述第二旋转盘1112转动连接；
其中，所述第一转轴1121以及所述第二转轴1122可相对于所述旋转构件111自转。
在本申请实施例中，所述第一转轴1121与所述第二转轴1122均为圆柱型。
在本申请实施例中，所述第一转轴1121或者所述第二转轴1122与所述旋转构件111可拆卸连接。
请参阅图2，在本申请实施例中，所述第一驱动组件21包括第一伸缩杆211、第二伸缩杆212以及位于所述第一伸缩杆211与所述第二伸缩杆212之间的第一连杆213，所述第一伸缩杆211的第一端与所述第一固定盘1211固定连接，所述第一伸缩杆211的第二端与所述第一连杆213固定连接，所述第二伸缩杆212的第一端与所述第二固定盘1212固定连接，所述第二伸缩杆212的第二端与所述第一连杆213固定连接；

在本申请的另一实施例中，所述第一伸缩杆211、所述第二伸缩杆212、所述第三伸缩杆221以及所述第四伸缩杆222中的任意一种也可以替换成空气弹簧。其中，当所述空气弹簧向远离所述收纳机构10的方向移动时，不存在阻尼力；当所述空气弹簧向靠近所述收纳机构10的方向移动时，存在一定的阻尼力；这是因为当所述空气弹簧向远离所述收纳机构10的方向移动时，所述空气弹簧被拉伸，所述空气弹簧内的气门打开，从而减小了所述空气弹簧与空气的阻力，进而使所述空气弹簧向远离所述收纳机构10的方向移动时不存在阻尼力；当所述空气弹簧向靠近所述收纳机构10的方向移动时，所述空气弹簧被压缩，所述空气弹簧内的气门关闭，从而增大了所述空气弹簧与空气的阻力，进而使所述空气弹簧向靠近所述收纳机构10的方向移动时存在一定的阻尼力。
如图4所示，为本申请实施例提供的可卷曲显示装置100处于完全收紧状态时的轴视图；如图5所示，为本申请实施例提供的可卷曲显示装置100处于完全收紧状态时的正视图；如图6所示，为本申请实施例提供的可卷曲显示装置100处于完全收紧状态时的侧视图；其中，当所述可卷曲显示装置100处于完全收紧状态时，所述第一伸缩杆211以及所述第三伸缩杆221均完全收纳于所述第一固定盘1211内，所述第二伸缩杆212以及所述第四伸缩杆222均完全收纳于所述第二固定盘1212内。
此时，所述转轴构件112支撑未收卷于所述收纳机构10的部分所述柔性显示面板40。
具体地，这部分未收卷于所述收纳机构10的所述柔性显示面板40用于所述可卷曲显示装置100的熄屏显示。当所述柔性显示面板40工作时，这部分未收卷于所述收纳机构10的所述柔性显示面板40的显示区可用于显示日期、天气、消息以及未接电话等。
在本申请实施例中，所述第一连杆213与所述柔性显示面板40的第一端固定连接，所述第二连杆223与所述柔性显示面板40的另一端固定连接；
其中，所述第一连杆213以及所述第二连杆223可相对于所述收纳机构10自由旋转。这样设计是为了方便所述第一连杆213以及所述第二连杆223对所述柔性显示面板40进行拉伸或者收紧。
在本申请实施例中，所述可卷曲显示装置100还包括紧固构件30，所述紧固构件30固定于所述第一固定盘1211或者所述第二固定盘1212中远离所述柔性显示面板40的一侧，所述紧固构件30用于驱动所述旋转构件111旋转，以使所述柔性显示面板40张紧。即，所述紧固构件30主要用于为所述柔性显示面板40提供继续收紧的力。
在本申请实施例中，所述紧固构件30包括马达或者回弹装置。其中，当所述可卷曲显示装置100由张开状态向收紧状态变化时，所述第一伸缩杆211、所述第二伸缩杆212、所述第三伸缩杆221以及所述第四伸缩杆222回缩，所述马达或者回弹装置驱动所述第一旋转盘1111或者所述第二旋转盘1112将所述柔性显示面板40收紧；此时，所述第一转轴1121收纳所述柔性显示面板40的方向与所述第二转轴1122收纳所述柔性显示面板40的方向相反，这样设置可以抵消所述柔性显示面板40在张开状态向收紧状态时产生的层间滑移。
如同书本折叠时，书本的边缘会“薄化、变尖”，这是一种层间滑移现象。由于所述柔性显示面板40也是很多薄层贴在一起的结构，在折叠或者卷曲时也会产生类似的现象，这一现象会随着卷曲、折叠的层数增加而加重，从而导致所述柔性显示面板40的损坏。因此通过所述第一转轴1121以及所述第二转轴1122对所述柔性显示面板40采用相反方向的折叠可以一定程度地改善这一问题。
在本申请的一种实施例中，所述紧固构件30为马达；此时当所述可卷曲显示装置100由张开状态向收紧状态变化时，所述马达驱动所述旋转构件111旋转，使所述柔性显示面板40缠绕在所述第一转轴1121以及所述第二转轴1122上；当所述第一驱动组件21与所述第二驱动组件22相对静止后，所述马达驱动所述旋转构件111继续旋转至一定的角度，让所述柔性显示面板40保持张紧。
在本申请的另一种实施例中，所述紧固构件30为回弹装置；在本申请实施例中，所述回弹装置为发条；此时当所述可卷曲显示装置100由张开状态向收紧状态变化时，所述回弹装置被压缩，所述回弹装置驱动所述旋转构件111旋转，使所述柔性显示面板40缠绕在所述第一转轴1121以及所述第二转轴1122上；当所述第一驱动组件21与所述第二驱动组件22相对静止后，所述回弹装置被压缩产生的惯性驱动所述旋转构件111继续旋转至一定的角度，让所述柔性显示面板40保持张紧。
在本申请实施例中，所述可卷曲显示装置100还包括锁止组件；其中，当所述第一驱动组件21与所述第二驱动组件22相对静止时，所述锁止组件用于锁定所述紧固构件30与所述旋转组件11之间的相对位置关系。
具体地，所述锁止组件主要用于对所述柔性显示面板40的收紧状态提供一个类似“刹车”的功能，所述锁止组件可以为插销型锁止构件、电子锁止型锁止构件、以及魔术贴型锁止构件中的任意一种。其中，在所述可卷曲显示装置100由收紧状态向张开状态变化的过程中，外力驱动所述驱动机构20将所述柔性显示面板40拉伸至一定程度，使所述第一驱动组件21与所述第二驱动组件22保持相对静止；此时，所述紧固构件30受到一定的拉伸力而保持拉伸状态，需要使用所述锁止组件锁定所述紧固构件30与所述旋转组件11之间的相对位置关系。
在所述可卷曲显示装置100由张开状态向收紧状态变化的过程中，解开所述锁止组件，所述紧固构件30由于被拉伸而产生回弹力，从而驱动所述旋转构件111反向旋转（定义所述可卷曲显示装置100由收紧状态向张开状态变化时所述旋转构件111的旋转方向为正转，所述可卷曲显示装置100由张开状态向收紧状态时所述旋转构件111的旋转方向为反转），所述旋转构件111带动所述转轴构件112反向旋转，所述转轴构件112从而将所述柔性显示面板40沿靠近所述收纳机构10的方向卷曲起来。
如图7所示，为本申请实施例提供的可卷曲显示装置100在收紧状态至张开状态之间变化时的轴视图；如图8所示，为本申请实施例提供的可卷曲显示装置100在收紧状态至张开状态之间变化时的正视图；如图9所示，为本申请实施例提供的可卷曲显示装置100在收紧状态至张开状态之间变化时的侧视图；
具体地，在本申请的上述实施例中，所述可卷曲显示装置100中的所述柔性显示面板40的卷曲过程如下：
如图7至图9所示，当所述可卷曲显示装置100由手机模式向平板模式转变（即所述可卷曲显示装置100由完全收紧状态向完全张开状态转变）时：
首先，提供一个外界驱动力驱动所述驱动机构20移动，使所述第一驱动组件21与所述第二驱动组件22产生相对滑动，其中，所述外界驱动力为手动拉力或者电动驱动力；
具体地，手动或电动拉伸所述第一连杆213以及所述第二连杆223，所述第一连杆213带动所述第一伸缩杆211、所述第三伸缩杆221以及所述柔性显示面板40的第一端沿着远离所述收纳机构10的方向移动；所述第二连杆223带动所述第二伸缩杆212、所述第四伸缩杆222以及所述柔性显示面板40的第二端沿着远离所述收纳机构10的方向移动。
之后，由于所述柔性显示面板40的两端被拉伸，且部分所述柔性显示面板40卷曲于所述第一转轴1121以及所述第二转轴1122上；因此，被拉伸的部分所述柔性显示面板40带动所述第一转轴1121以及所述第二转轴1122正向旋转，所述第一转轴1121以及所述第二转轴1122带动所述旋转构件111正向旋转，从而使所述第一转轴1121以及所述第二转轴1122释放更多的所述柔性显示面板40，直到被所述转轴构件112收纳的部分所述柔性显示面板40全部被拉出。此时，所述旋转构件111带动所述紧固构件30产生部分回弹力，所述紧固构件30受到一定的拉伸力而保持拉伸状态。
最后，使所述锁止构件处于锁止状态，以锁定所述紧固构件30与所述旋转组件11之间的相对位置关系，从而使所述第一驱动组件21与所述第二驱动组件22之间的位置保持相对静止。
具体地，在所述可卷曲显示装置100由完全收紧状态向完全张开状态转变时，所述第一转轴1121以及所述第二转轴1122会正向旋转90°；其中，在所述第一转轴1121或者所述第二转轴1122正向旋转过程中，所述第一转轴1121或者所述第二转轴1122与所述连接构件122会发生接触。为了防止所述柔性显示面板40与所述转轴构件112因接触而发生损坏，在所述连接构件122靠近所述柔性显示面板40的一侧设置有多个防撞子构件。在本申请实施例中，所述防撞子构件包括多个微型滑轮。
在本申请实施例中，在本申请另一实施例中，可以在所述连接构件122靠近所述柔性显示面板40的一侧表面涂覆润滑剂，以减小所述连接构件122靠近所述柔性显示面板40的一侧表面的摩擦系数，从而加强所述连接构件122与所述柔性显示面板40之间的润滑度，以避免所述柔性显示面板40与所述转轴构件112因接触而发生损坏。
在本申请实施例的另外一种情况时，当所述可卷曲显示装置100由平板模式向手机模式转变（即所述可卷曲显示装置100由完全张开状态向完全收紧状态转变）时：
首先，使所述锁止构件处于解开状态；此时，所述紧固构件30受到回弹力的作用驱动所述旋转构件111反向旋转。
之后，所述旋转构件111反向旋转带动所述第一转轴1121以及所述第二转轴1122反向旋转，从而使所述第一转轴1121以及所述第二转轴1122收卷更多的所述柔性显示面板40，直到所述第一伸缩杆211以及所述第三伸缩杆221均收纳于所述第一固定盘1211内，所述第二伸缩杆212以及所述第四伸缩杆222均收纳于所述第二固定盘1212内，此时所述柔性显示面板40处于完全收紧状态，未被收卷的部分所述柔性显示面板40的显示区用于所述可卷曲显示装置100的熄屏显示。其中，由于所述第一伸缩杆211、所述第二伸缩杆212、所述第三伸缩杆221以及所述第四伸缩杆222在回弹过程中可以提供阻尼力，从而使所述可卷曲显示装置100由完全张开状态向完全收紧状态转变的过程可以稳定进行。
如图10所示，为本申请实施例提供的可卷曲显示装置100在完全张开状态时的第一种轴视图；如图11所示，为本申请实施例提供的可卷曲显示装置100在完全张开状态时的第一种侧视图；其中如图10以及图11所示，当所述第一伸缩杆211、所述第二伸缩杆212、所述第三伸缩杆221以及所述第四伸缩杆222拉到最长时，所述柔性显示面板40处于完全平展状态，所述第一转轴1121以及所述第二转轴1122由于正向旋转90°使得所述柔性显示面板40处于所述第一转轴1121以及所述第二转轴1122之间。因此，为了不影响所述可卷曲显示装置100的显示效果，可以手动拆卸位于所述柔性显示面板40正面的所述第一转轴1121，取下的所述第一转轴1121可以用于所述可卷曲显示装置100的手写笔、支撑架、以及遥控器等。
在本申请实施例中，当所述柔性显示面板40处于完全张开状态时，所述第一驱动组件21与所述第二驱动组件22沿平行于所述柔性显示面板40的长度方向错位设置。由于所述第一驱动组件21与所述第二驱动组件22并非水平放置，当所述第一驱动组件21以及所述第二驱动组件22沿远离所述收纳机构10的方向移动时，所述第一连杆213的远离所述收纳机构10的一端的底面与所述第二驱动组件22远离所述收纳机构10的一端的顶面恰好在同一水平面上，从而保证了所述柔性显示面板40完全平展且不倾斜。
如图12所示，为本申请实施例提供的可卷曲显示装置100在完全张开状态时的第二种轴视图；如图13所示，为本申请实施例提供的可卷曲显示装置100在完全张开状态时的第二种侧视图；其中如图12以及图13所示，当所述第一伸缩杆211、所述第二伸缩杆212、所述第三伸缩杆221以及所述第四伸缩杆222拉到最长时，所述柔性显示面板40处于完全平展状态，所述第一转轴1121以及所述第二转轴1122由于正向旋转90°使得所述柔性显示面板40处于所述第一转轴1121以及所述第二转轴1122之间。因此，为了不影响所述可卷曲显示装置100的显示效果，可以手动拆卸位于所述柔性显示面板40正面的所述第一转轴1121，之后将所述旋转构件111归位，再将取下的所述第一转轴1121插回所述第一旋转盘1111与所述第二旋转盘1112之间，从而不影响所述柔性显示面板40的显示。此时，所述第一转轴1121以及所述第二转轴1122同时支撑所述柔性显示面板40。
相对于现有技术，本申请实施例提供的所述可卷曲显示装置100具有以下几个优势：
第一，所述可卷曲显示装置100采用可以随着所述旋转构件111旋转的第一转轴1121以及所述第二转轴1122，且所述第一转轴1121收纳所述柔性显示面板40的方向与所述第二转轴1122收纳所述柔性显示面板40的方向相反，可以抵消所述柔性显示面板40在收紧或者拉伸时产生的层间滑移；同时所述柔性显示面板40在所述驱动机构20的运动下实现双向拉伸，增大了所述柔性显示面板40的折叠半径，进而使得被收纳的部分所述柔性显示面板40在伸缩过程中始终大致保持在所述旋转组件11上，避免了所述柔性显示面板40在伸缩过程中与所述收纳结构产生挤压而受到损伤的问题。另一方面，本申请实施例提供的所述可卷曲显示装置100采用“双向拉伸的双转轴”的卷曲方案，其收纳速度可以是传统“单向拉伸的单转轴”的卷曲方案的可卷曲显示装置100的收纳速度的2倍。
第二，所述可卷曲显示装置100采用了所述驱动机构20与所述紧固构件30结合的设计，在所述柔性显示面板40收紧或者张开时，所述第一伸缩杆211、所述第二伸缩杆212、所述第三伸缩杆221、以及所述第四伸缩杆222与所述紧固构件30的力相互抵消，可以使所述柔性显示面板40在收紧状态至张开状态的变化过程中更加平稳。
第三，所述可卷曲显示装置100采用了将所述第一转轴1121与所述第二转轴1122分别与所述旋转构件111可拆卸连接的设计，从而当所述第一伸缩杆211、所述第二伸缩杆212、所述第三伸缩杆221以及所述第四伸缩杆222拉到最长时，所述柔性显示面板40处于完全平展状态，所述第一转轴1121以及所述第二转轴1122由于正向旋转90°使得所述柔性显示面板40处于所述第一转轴1121以及所述第二转轴1122之间。因此，为了不影响所述可卷曲显示装置100的显示效果，可以手动拆卸位于所述柔性显示面板40正面的所述第一转轴1121，以获取更好的观看体验。
第四，当所述柔性显示面板40处于完全张开状态时，所述第一驱动组件21与所述第二驱动组件22沿平行于所述柔性显示面板40的长度方向错位设置。由于所述第一驱动组件21与所述第二驱动组件22并非水平放置，当所述第一驱动组件21以及所述第二驱动组件22沿远离所述收纳机构10的方向移动时，所述第一连杆213的远离所述收纳机构10的一端的底面与所述第二驱动组件22远离所述收纳机构10的一端的顶面恰好在同一水平面上，从而保证了所述柔性显示面板40处于完全张开状态时，所述柔性显示面板40完全平展且不倾斜。
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。
以上对本申请实施例所提供的一种可卷曲显示装置进行了详细介绍，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方法及其核心思想；同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
