所述驱动部30驱动所述柔性显示面板10由展开状态切换为卷曲状态且驱动所述辅助结构20由伸展状态切换为折叠状态时，驱动所述辅助结构20的第四端向靠近所述第一卷轴325的方向移动，驱动所述第一卷轴325转动，以带动所述第二端12向靠近所述第一卷轴325的方向移动，且使所述柔性显示面板10缠绕在所述第一卷轴325上。需要说明的是，第一卷轴325的转动、以及辅助结构20的第四端向靠近第一卷轴325的方向的移动，二者均可带动柔性显示面板的第二端向靠近第一卷轴325的方向移动。所述驱动部30驱动所述柔性显示面板10由卷曲状态切换为展开状态且驱动所述辅助结构20由折叠状态切换为伸展状态时，驱动所述第一卷轴325转动，使缠绕在所述第一卷轴325上的所述柔性显示面板10脱离所述第一卷轴325，并驱动所述第四端向背离所述第一端11的方向移动，以带动所述第二端12向背离所述第一端11的方向移动。
本申请实施例提供的柔性显示设备100，驱动部30驱动柔性显示面板10切换为展开状态且驱动辅助结构20切换为伸展状态时，所述辅助结构20的第四端带动柔性显示面板10的第二端12向背离第一卷轴325的方向移动，辅助结构20对柔性显示面板10施加拉力，使得柔性显示面板在展开状态时平整度较好，避免柔性显示面板因柔性较低而导致展开时不平整或者扭曲的情况，有助于提升用户的使用体验；驱动部30驱动柔性显示面板10切换为卷曲状态且驱动辅助结构20切换为折叠状态时，柔性显示面板10缠绕在第一卷轴325上，可使得柔性显示设备100的体积较小，便于用户携带。
辅助结构20的第三端与第一卷轴325的距离很小。辅助结构20在展开状态时，杆部201的第三端与第一卷轴325之间的距离小于杆部201的第四端与第一卷轴325之间的距离。辅助结构20的材料为硬性材料。
在一个实施例中，辅助结构20在伸展状态时，柔性显示面板10只有第一端与第一卷轴325相连，其他区域均脱离第一卷轴325。辅助结构20的第四端与第一卷轴325之间的距离等于柔性显示面板10展开状态时在第二方向上的尺寸，从而使柔性显示面板10在展开状态时平整度较好，不存在褶皱。
柔性显示面板10的第一端11与第一卷轴325相连，第一卷轴325转动时带动柔性显示面板10缠绕在第一卷轴325上，或者使柔性显示面板10脱离第一卷轴325。通过辅助结构20及第一卷轴325的配合带动柔性显示面板10的第二端12运动，从而实现柔性显示面板10展开状态与卷曲状态的切换。柔性显示面板10由卷曲状态切换为展开状态时第一卷轴325的转动方向、与柔性显示面板10由展开状态切换为卷曲状态时第一卷轴325的转动方向相反。
柔性显示面板10在展开状态与卷曲状态时，柔性显示面板10在第一端11延伸方向(以下简称第一方向)上的尺寸不变；在柔性显示面板10在展开状态时柔性显示面板的边缘的延伸方向(以下简称第二方向，与第一方向垂直)上，柔性显示面板10在展开状态与卷曲状态时的尺寸不同。柔性显示面板10处于卷曲状态时在第二方向上的尺寸小于处于展开状态时在第二方向上的尺寸。柔性显示面板10在展开状态时所占的空间大于在卷曲状态时所占的空间。辅助结构20处于伸展状态时在第二方向上的尺寸大于处于折叠状态时在第二方向上的尺寸。辅助结构20在伸展状态时所占的空间大于在折叠状态时所占的空间。
在一个实施例中，所述柔性显示设备100还包括收容部40。第一卷轴325、驱动部30及所述辅助结构20的第三端可始终收容于所述收容部40中。所述柔性显示面板10在卷曲状态且所述辅助结构20在折叠状态时，所述柔性显示面板10、所述驱动部30及所述辅助结构20收容于所述收容部40；所述柔性显示面板10在展开状态且所述辅助结构20在展开状态时，所述柔性显示面板10及所述辅助结构20至少部分通过露出所述收容部40。如此设置，柔性显示设备在不显示时，柔性显示面板10、驱动部30及辅助结构20容纳在收容部40中，柔性显示设备在不显示时，驱动部30收容于收容部，有助于提升柔性显示设备100的美观性。收容部40可设有开口，柔性显示面板10及辅助结构20通过开口露出收容部40。并且柔性显示面板10的第一端始终收容在收容部40中，通过第二端相对于收容部40运动来实现展开状态与卷曲状态的切换，也即是柔性显示面板通过向一侧运动来实现展开状态与卷曲状态的切换。
在一个实施例中，所述收容部40由第一壳体41及第二壳体42组装而成。如此设置，便于将驱动部30、辅助结构20的第三端、第一卷轴325及柔性显示面板10的第一端安装在收容部40中，降低组装的复杂度。
在一个实施例中，参见图5，所述柔性显示设备100还包括固定设置的轴杆50，轴杆50可固定安装在收容部40内，轴杆50不可相对于收容部40转动及移动。所述柔性 显示设备100还包括与所述轴杆50固定连接的连接杆51，轴杆50通过连接杆51固定安装在收容部40内。连接杆51可设有至少两个安装孔，所述柔性显示设备100还包括与所述安装孔一一对应的连接件，各连接件分别穿过对应的安装孔将连接杆51固定安装在收容部40。连接件例如可为螺钉。在一些实施例中，轴杆50通过连接杆51固定在收容部40的第一壳体41上；连接杆51上可设有两个安装孔。
所述辅助结构20包括杆部201，所述杆部201可绕所述轴杆50转动。所述杆部201的第三端与所述驱动部30相连。杆部201的第三端靠近柔性显示面板10的第一端。辅助结构包括杆部201，杆部201包括第三端及第四端。
所述驱动部30驱动所述辅助结构20切换为伸展状态时，驱动所述杆部201绕所述轴杆50转动以使所述杆部201的第四端向背离所述第一卷轴325的方向移动；所述驱动部驱动所述辅助结构20切换为所述折叠状态时，驱动所述杆部201绕所述轴杆50转动以使所述杆部201的第四端向靠近所述第一卷轴325的方向移动。
柔性显示面板10切换为展开状态且辅助结构20切换为伸展状态时，杆部201的第四端带动柔性显示面板10的第二端12向背离第一卷轴325的方向移动，使柔性显示面板10展开。如此杆部201在第二方向上的尺寸增大，带动柔性显示面板10在第二方向上的尺寸增大，可使得柔性显示面板10在展开状态时的平整度较好。柔性显示面板10切换为卷曲状态且辅助结构20切换为折叠状态时，杆部201的第四端向靠近第一卷轴325的方向移动，同时柔性显示面板10的第二端12向靠近第一卷轴325的方向移动，如此可使得柔性显示面板10及杆部201在第二方向上的尺寸均减小，从而使柔性显示设备的体积减小。
在一个实施例中，辅助结构20包括至少两个杆部201。如此两个杆部201的第四端共同带动柔性显示面板10的第二端12移动，更有助于改善柔性显示面板10在展开状态时的不平整的问题。
在一个实施例中，所述柔性显示设备100还包括连杆321，所述连杆321上设有通槽327，所述杆部201的第四端与所述通槽327可相对移动及可相对转动地连接；所述第二端12与所述连杆321相连，所述杆部201的第四端通过所述连杆321与所述第二端12相连。所述杆部201的第四端向背离或靠近所述第一卷轴325的方向移动时，所述杆部201的第四端相对于所述通槽327移动及转动。通槽327的延伸方向与连杆321的延伸方向相同。连杆321为非柔性材料，例如连杆321的材料为金属或塑料。
如此设置，所述杆部201的第四端向背离或靠近所述第一卷轴325的方向移动时，杆部201的第四端相对于连杆321移动及转动，杆部201带动连杆321向背离或靠近所述第一卷轴325的方向移动，柔性显示面板10的第二端随连杆321移动。由于所述第二端12与所述连杆321相连，则在杆部201相对于连杆321移动时，柔性显示面板10的第二端不会相对于连杆321移动，柔性显示面板不会发生褶皱，可避免第四端与第二端12直接相连导致杆部201移动时导致柔性显示面板10发生褶皱的情况。
在一个实施例中，所述杆部201上设有条形槽，所述轴杆50穿设所述条形槽，且所述条形槽可相对于所述轴杆50移动及转动。所述驱动部30驱动所述辅助结构20切换为折叠状态时，驱动所述条形槽相对于所述轴杆转动及移动，使所述杆部201的第三端与所述轴杆50之间的距离增大，带动所述杆部201的第四端向靠近所述第一卷轴325的方向移动；所述驱动部30驱动所述辅助结构20切换为所述伸展状态时，驱动所述条形槽相对于所述轴杆50转动及移动，使所述杆部201的第三端与所述轴杆50之间的距离减小，带动所述杆部201的第四端向背离所述第一卷轴325的方向移动。
通过在杆部201上设置条形槽，辅助结构20切换为折叠状态时，轴杆50与杆部201的第三端之间的距离增大，轴杆50与杆部201的第四端之间的距离减小，可使得杆部201的第三端及第四端与柔性显示面板位于同侧的边缘之间的距离均较小，避免杆部201的第三端或第四端与位于柔性显示面板位于同侧的边缘之间的距离较大，而导致柔性显示设备在卷曲状态时体积较大，有助于减小柔性显示面板在卷曲状态时柔性显示设备的体积。
在一个实施例中，在所述杆部201的延伸方向上，所述条形槽靠近所述杆部201的第三端的端部到所述杆部201的第三端的距离、小于所述条形槽远离所述杆部201的第三端的端部到所述杆部201的第四端的距离。辅助结构20在切换为伸展状态时，条形槽相对于轴杆50移动，使条形槽靠近的第三端的端部向靠近轴杆50的方向移动；通过设置条形槽靠近杆部201的第三端的端部到杆部201的第三端的距离、小于条形槽远离所述杆部201的第三端的端部到杆部201的第四端的距离，可使得辅助结构在伸展状态时，杆部201的第四端与轴杆50之间的距离较大，从而使柔性显示面板在展开状态时的面积，提升柔性显示面板的显示区域的大小。
在一个实施例中，辅助结构20在伸展状态时，轴杆50与条形槽的靠近第三端的端部相抵。如此可使得杆部201的第四端与轴杆50之间的距离最大。
在一个实施例中，条形槽远离所述杆部201的第三端的端部到杆部201的第四端的 距离大致等于条形槽远离所述杆部201的第三端的端部到杆部201的第三端的距离。辅助结构20在折叠状态时，条形槽远离所述杆部201的第三端的端部与轴杆50相抵。轴杆50到第一卷轴325两端的距离可相同。如此，辅助结构20在折叠状态时，杆部201的第三端到轴杆50的距离与杆部201的第四端到轴杆50的距离相等，有助于减小柔性显示设备在卷曲状态时的体积。
在一个实施例中，参见图6，所述辅助结构20包括交叉设置的第一杆部21与第二杆部22。第一杆部21包括第三端211及与第三端相对的第四端212，所述第一杆部21设有条形槽213；所述第二杆部22包括第三端221及与第三端相对的第四端222，所述第二杆部22设有条形槽223。所述轴杆50穿设所述第一杆部21的条形槽213与所述第二杆部22的条形槽223，且所述第一杆部21的条形槽213与所述第二杆部22的条形槽223可相对于所述轴杆50移动及转动。
所述驱动部30驱动所述辅助结构20切换为折叠状态时，驱动所述第一杆部21的条形槽213与所述第二杆部22的条形槽223相对于所述轴杆50转动及移动，使所述第一杆部21的第三端211及所述第二杆部22的第三端221与所述轴杆50之间的距离均增大，所述第一杆部21的第三端211与所述第二杆部22的第三端221之间的距离增大，所述第一杆部21的第四端212与所述第二杆部22的第四端222向靠近所述第一端11的方向移动。
所述驱动部30驱动所述辅助结构20切换为所述伸展状态时，驱动所述第一杆部21的条形槽213与所述第二杆部22的条形槽223相对于所述轴杆50转动及移动，使所述第一杆部21的第三端211及所述第二杆部22的第三端221与所述轴杆50之间的距离均减小，所述第一杆部21的第三端211与所述第二杆部22的第三端221之间的距离减小，带动所述第一杆部21的第四端212与所述第二杆部22的第四端222向远离所述第一卷轴325的方向移动。
通过设置第一杆部21与第二杆部22交叉设置，第一杆部21的第四端与第二杆部22的第四端均与连杆321相连，辅助结构20切换为伸展状态时，第一杆部21的第四端与第二杆部22的第四端之间的距离增大，共同带动连杆321向背离第一卷轴325的方向转动，可使得连杆321的两端移动的距离大致相等，进一步保证柔性显示面板的平整性。
在一个实施例中，柔性显示面板10在卷曲状态且辅助结构20在折叠状态时，第一杆部21的第三端211、第一杆部21的第四端212、第二杆部22的第三端221及第二杆 部22的第四端222均不超出位于同侧的柔性显示面板10的边缘，如此可使得柔性显示面板在折叠状态时，柔性显示设备在第一方向上的尺寸较小，柔性显示设备的体积减小。
在一个实施例中，柔性显示面板10在展开状态且辅助结构20在伸展状态时，第一杆部21的条形槽213靠近第一杆部21第三端的端部与轴杆50抵接，第二杆部22的条形槽223靠近第二杆部22第三端的端部与轴杆50抵接。柔性显示面板10在卷曲状态且辅助结构20在折叠状态时，第一杆部21的条形槽213背离第一杆部21第三端的端部与轴杆50抵接，第二杆部22的条形槽223背离第二杆部22第三端的端部与轴杆50抵接。如此设置，有助于防止第一杆部21的条形槽213与第二杆部22的条形槽223相对于轴杆50相对移动，进而避免第一杆部21与第二杆部22相对于轴杆50移动而影响柔性显示面板的平整度。
在一个实施例中，参见图7，连杆321设有两个间隔排布的通槽327，第一杆部21的第四端与一个通槽327可相对转动及可相对移动地连接，第二杆部22的第四端与另一个通槽327可相对转动及可相对移动地连接。所述柔性显示面板10切换为展开状态，且所述辅助结构20切换为伸展状态时，第一杆部21的第四端212与第二杆部22的第四端222带动连杆321向背离第一端11的方向移动，同时第一杆部21的第四端212与第二杆部22的第四端222在对应的通槽327内移动及转动，第一杆部21的第四端212与第二杆部22的第四端222之间的距离减小。
在一个实施例中，第一杆部21的第四端及第二杆部22的第四端分别通过连接结构328与连杆321相连。连接结构328包括连接柱及套设在连接柱上的两个限位挡板。连杆321为中空结构，且朝向第一卷轴的一侧开口。第一杆部21的第四端及第二杆部22的第四端通过连杆321的开口插入连杆321中。连接结构328的连接柱穿设通槽327及第一杆部21的第四端上开设的安装孔，且连接柱的两端分别露出，两个限位挡板分别套设在连接柱上，且分别位于连杆321两侧，连接柱可在通槽327内移动及转动，从而连接结构328将第一杆部21的第四端与连杆321相连，且第一杆部21的第四端可相对于连杆321转动及移动。第二杆部22的第四端也通过同样的连接结构328与连杆321连接。
在一个实施例中，再次参见图5及图6，所述驱动部30包括第一电机311、传动件312和连接部313，所述连接部313与所述杆部201的第三端可相对转动地连接，且所述连接部313与所述传动件312配合。所述第一电机311驱动所述传动件312转动，所述传动件312带动所述连接部313相对于所述轴杆50移动，从而所述连接部313带动 所述杆部201的第三端相对于所述轴杆50运动。具体的，连接部313带动杆部201的第三端相对于轴杆50移动及转动。
在一个实施例中，传动件312为丝杆，丝杆的延伸方向与第一端11的延伸方向大致齐平。连接部313可与丝杆螺纹连接。第一电机311带动丝杆转动，丝杆的转动带动连接部313在沿丝杆移动，从而带动杆部201的第三端相对于轴杆50转动。
在一个实施例中，所述驱动部30包括两个子驱动组件31，其中一个子驱动组件31驱动第一杆部21运动，另一个子驱动组件31驱动第二杆部22运动。每一子驱动组件31包括第一电机311、传动件312和连接部313。
在一个实施例中，第一电机311及传动件312固定在第一壳体41的内壁上。如此，可防止第一电机311与传动件312发生移动，而影响柔性显示设备的工作。
在一个实施例中，所述驱动部30包括动力组件32，所述动力组件32与所述第一卷轴325相连，带动所述第一卷轴325转动；所述辅助结构20的端部及所述第二端12分别与所述连杆321相连。
在一个实施例中，参见图5、图8与图9，所述动力组件32包括第二电机324。所述第二电机324带动所述第一卷轴325转动，所述卷轴325的转动使处于展开状态的柔性显示面板10缠绕在所述第一卷轴325上，或使缠绕在所述第一卷轴325的柔性显示面板10脱离第一卷轴325。
如此，动力组件的结构比较简单，易于实现。
在一个实施例中，所述柔性显示设备还包括柔性背板60，所述柔性背板60具有展开状态与卷曲状态；所述驱动部30驱动所述柔性背板0在卷曲状态与展开状态之间切换。所述柔性背板60与所述柔性显示面板10在展开状态时，所述辅助结构20位于所述柔性背板60与所述柔性显示面板10之间。通过设置柔性背板60，当柔性显示面板10与柔性背板60处于展开状态时，辅助结构20位于柔性背板60与柔性显示面板10之间，辅助结构20不外露，可提升柔性显示设备的美观度，提升用户的使用体验；驱动部30可同时驱动柔性显示面板10及柔性背板60切换为卷曲状态，柔性背板60的设置不会增大柔性显示设备的体积。
在一个实施例中，柔性背板60处于卷曲状态时，柔性背板60收容于收容部40中。
在一个实施例中，所述动力组件32同时驱动所述柔性显示面板10及所述柔性背板60在展开状态与卷曲状态之间切换。所述柔性显示设备还包括第二卷轴326。第二卷轴 326收容于收容部40中。所述动力组件32还包括第一齿轮322和第二齿轮323，所述柔性背板60的一端与所述第二卷轴326相连。所述第一齿轮322与所述第二齿轮323啮合，所述第一齿轮322带动所述第一卷轴325转动，所述第二齿轮323带动所述第二卷轴326转动。所述第二电机324带动所述第一齿轮322或所述第二齿轮323中的其中一个转动。
由于第一齿轮322与第二齿轮323啮合，第二电机324带动其中一个齿轮转动时，该齿轮带动另一个齿轮转动，第一齿轮322与第二齿轮323的转动方向相反。图示实施例中，第二电机324通过传送带与第二齿轮323相连，第二电机324通过传送带带动第二齿轮323转动，第二齿轮323的转动带动第一齿轮322转动。在其他实施例中，第二电机324可通过传送带带动第一齿轮322转动。
所述第二电机324运转时，所述第一齿轮322与第二齿轮323转动，带动所述第一卷轴325与所述第二卷轴326转动，使处于展开状态的柔性显示面板10缠绕在所述第一卷轴325上，且使处于展开状态的柔性背板60缠绕在所述第二卷轴326上，或者使缠绕在所述第一卷轴325上的柔性显示面板10展开，且使缠绕在所述第二卷轴326的柔性背板60展开。
如此设置，通过一个第二电机324可同时带动柔性背板60及柔性显示面板10同时展开或同时卷曲，可简化驱动部30的结构复杂度，降低柔性显示设备的成本。
在一个实施例中，柔性显示设备可设有两个第一齿轮322和两个第二齿轮323。两个第一齿轮322分别与第一卷轴325的两端相连，两个第二齿轮323分别与第二卷轴326的两端相连。第一卷轴325的延伸方向与第二卷轴326的延伸方向可相同。
在一个实施例中，第二电机324、第一齿轮322及第二齿轮323可固定安装在第二壳体42的内壁上，防止第二电机324、第一齿轮322及第二齿轮323相对于第二壳体42移动。
在一个实施例中，在驱动柔性显示面板切换为卷曲状态且辅助结构20切换为折叠状态时，可对第一电机311与第二电机324的运转时间进行控制，使第一电机311的运转时间稍微早于第二电机324的运转时间，如此使得连杆321先向靠近第一卷轴325的方向移动，随后第一卷轴325转动使柔性显示面板转动，使连杆321对柔性显示面板10的第二端产生拉伸力，保证柔性显示面板卷曲状态时各部分的平整度，避免柔性显示面板发生褶皱。
在一个实施例中，柔性背板60的一端与第二卷轴326相连，柔性背板60的另一端与连杆321相连。柔性背板60可通过粘结材料与连杆321的侧面粘结在一起。如此，第一杆部21与第二杆部22的第四端向背离柔性显示面板10的方向移动时，带动柔性背板60移动，使柔性背板60顺利展开，避免柔性背板60发生褶皱。
在一个实施例中，再次参见图8及图9，所述柔性显示设备100还包括拉锁组件70，所述柔性显示面板的相对两侧分别设有拉锁组件。所述拉锁组件70包括第一拉链条72、第二拉链条73及固定设置的锁扣部71，所述第一拉链条72设置在所述柔性显示面板10的侧边，所述第二拉链条73设置在所述柔性背板60的侧边。
所述驱动部30同时驱动所述柔性显示面板10及所述柔性背板60由展开状态切换为卷曲状态时，带动所述第一拉链条72与所述第二拉链条73卷曲，所述第一拉链条72与所述第二拉链条73相对于所述锁扣部71移动，所述锁扣部71使处于扣合状态的第一拉链条72与第二拉链条73分离。所述驱动部30同时驱动所述柔性显示面板10及所述柔性背板60由卷曲状态切换为展开状态时，带动处于卷曲状态的所述第一拉链条72与所述第二拉链条73展开，所述第一拉链条72与所述第二拉链条73相对于所述锁扣部71移动，所述锁扣部71使第一拉链条72与第二拉链条73扣合。
如此设置，柔性显示面板10及柔性背板60展开时，第一拉链条72与第二拉链条73扣合，将柔性显示面板10与柔性背板60位于同一侧的侧边相连，柔性显示设备看起来是一个完整的结构，用户无法通过侧边缘看到辅助结构20，可提升柔性显示设备100的美观度，提升用户的使用体验。柔性显示面板10及柔性背板60卷曲时，第一拉链条72与第二拉链条73随着卷曲并收容在收容部40中，不会露出收容部40。
在一个实施例中，锁扣部71可固定设置在第二壳体42的内壁上。如此锁扣部71固定不动，第一拉链条72与第二拉链条73移动，第一拉链条72与第二拉链条73经过锁扣部71时，锁扣部71使第一拉链条72与第二拉链条73扣合或分离。
在一个实施例中，参见图10，柔性显示设备还包括覆晶薄膜(COF)81、印制电路板(PCB)82及控制电路板90，覆晶薄膜81的一端与柔性显示面板电连接，另一端与印刷电路板82的一端电连接，印刷电路板82的另一端与控制电路板90电连接。覆晶薄膜81、印刷电路板82及控制电路板90收容于收容部40中。
