技术领域
本发明涉及柔性显示装置技术领域，特别涉及一种柔性显示模组及具有该柔性显示模组的电子装置。
背景技术
随着显示终端的普及，人们对显示设备的要求越来越严格，既要求他们结构紧凑，便于携带；同时又希望其可以在休闲娱乐时提供更大的显示尺寸。这对于传统的显示设备来说是相互制约的，想要便于携带，则其屏幕尺寸必然要减小，娱乐体验变差；若是提供更大的显示屏，则其尺寸必然变大，不易携带。柔性屏幕的出现，为上述问题的解决提供了可能性。由于柔性屏不具有刚性，所以需要一定的机械结构来支撑并引导柔性屏的弯折；对于大多数柔性显示装置，都是经一次折叠，将整个屏幕隐藏在装置内部，在需查看天气，时间，接电话等日常琐事的情况下，需每次将装置进行展开，之后又进行折叠，增加了柔性屏不必要的弯折，降低了柔性屏的使用寿命；又因便携性的限制，使得一次折叠的显示装置屏幕尺寸受到制约，同时，对于多次折叠的装置，其折叠厚度必然增加，便携性变差。因此需设计一种既便于携带，使用寿命长，同时又能提供大尺寸显示的装置。
发明内容

所述的柔性显示模组，其中，所述侧壁靠近第一支撑件的上表面处设置有条形的突起，所述连接机构的弧面上方对应地设置为阶梯状结构；所述侧壁靠近第二支撑件的上表面处设置有条形的突起，所述连接机构的弧面上方对应地设置为阶梯状结构。
所述的柔性显示模组，其中，所述连接机构的两侧分别设置有两个矩形凹槽，对应地，第一支撑件延伸出的侧壁内侧表面设置有矩形凹槽，第二支撑件延伸出的侧壁内侧表面也设置有矩形凹槽，在连接机构与第一支撑件/第二支撑件对应的矩形凹槽内设置有铰链装置。
所述的柔性显示模组，其中，所述铰链装置包括：公轴、母轴、弹簧、挡圈、柱体部以及接合部，所述公轴具有与第一支撑件/第二支撑件的矩形凹槽对应的公矩形部，以及固定在公矩形部上的柱体部和接合部，所述母轴具有与连接机构的的矩形凹槽对应的母矩形部，以及固定在母矩形部上的并且与公轴的接合部相对应的接合部，所述母轴还设置有贯通孔，用于供公轴的柱体部穿过，所述母轴的贯通孔内部设置有凸台，公轴的柱体部的自由端处设置有挡圈，所述柱体部 上套设有弹簧，并且所述弹簧由凸台和挡圈限位。
所述的柔性显示模组，其中，所述公轴的接合部与母轴的接合部在接合处设置有对应的锯齿。

再如图3所示，所述第一支撑件110通过连接机构150与第二支撑件120相连接。第一支撑件110与第二支撑件120在与连接机构150连接的连接处的结构类似，因此以图4中示出的第二支撑件为例对该连接处进行描述。
第二支撑件120与连接机构150相连的一端具有一个弧形凹槽面124。此外，所述第二支撑件120在所述弧形凹槽面124的两侧延伸出侧壁，两个侧壁上对应地设置有弧形的滑轨121，并且滑轨121与弧形凹槽面124的弯曲方向大致相同。此外，所述侧壁靠近第二支撑件120的上表面处还设置有条形的突起(图中未标示)。
对应地，如图5所示，所述连接机构150的边缘具有与第二支撑件120的所述弧形凹槽面124配合的弧面(图5中未标示)，使得连接机构150的弧面能够沿着所述弧形凹槽面124运动。并且，在连接机构150的两侧分别设置有两个滑块152，其中靠近第二支撑件120的滑块152能够在第二支撑件的滑轨121中移动，而靠近第一支撑件110的滑块152能够在第一支撑件110的滑轨111中移动。此外，所述连接机构150的弧面上方设置为阶梯状结构153，使其能够分别与第一支撑件110的突起和第二支撑件120的突起产生限位作用，即当连接机构150旋转至与第一支撑件110处于同一水平面时，连接机构150靠近第一支撑件 110的阶梯状结构153与第一支撑件110的突起相贴合，从而防止连接机构150继续相对第一支撑件110转动；同理，当连接机构150旋转至与第二支撑件120处于同一水平面时，连接机构150靠近第二支撑件120的阶梯状结构153与第二支撑件120的突起相贴合，从而防止连接机构150继续相对第一支撑件120转动。
再结合图4至图6所示，所述连接机构150的两侧分别设置有两个矩形凹槽151，并且对应地，第一支撑件110延伸出的侧壁内侧表面设置有矩形凹槽113，第二支撑件120延伸出的侧壁内侧表面也设置有矩形凹槽123。在连接机构150与第一支撑件110/第二支撑件120对应的矩形凹槽内设置有铰链装置170。
具体请见图6，所述铰链装置170主要包括：公轴171、母轴172、弹簧173、挡圈174、柱体部175以及接合部176等。所述公轴171具有与第一支撑件110/第二支撑件120的矩形凹槽113/123对应的公矩形部，以及固定在公矩形部上的柱体部175和接合部176，所述接合部176大体为圆筒状，并且远离矩形部的一侧设置有锯齿。所述母轴172具有与连接机构150的的矩形凹槽151对应的母矩形部，以及固定在母矩形部上的接合部176，所述母轴172还设置有贯通孔用于供公轴171的柱体部175穿过。此外，所述母轴172的贯通孔内部设置有凸台(图中未示出)，公轴171的柱体部175的自由端处设置有挡圈174，所述柱体部175上套设有弹簧173，并且所述弹簧173由凸台和挡圈174限位。弹簧173在常态下处于压缩的状态，因此公轴171与母轴172始终相互挤压。
所述锯齿状的接合部176的锯齿为等距布置，并且每两个相邻的锯齿之间的距离可以依据实际需要进行选择，例如每相邻的两个锯齿之间的距离为接合部176的周长的1/12，这样一来，几乎可以实现公轴171与母轴172之间以任意角度进行固定。当然，所述接合部176的形状不仅限于图6所示的锯齿状，还可以是波浪状，或者在特定角度上设置对应的凹槽和突起，例如每90度位置设置对应的凹槽和突起。
将公轴171的公矩形部固定安装在第一支撑件110/第二支撑件120的矩形凹槽113/123，母轴172的母矩形部固定安装在连接机构的矩形凹槽151内。当展开柔性屏时，第一支撑件110/第二支撑件120与连接机构150均处于同一水平面上，因此公轴171上的公矩形部与母轴172上的母矩形部是平行的；当需要折叠柔性屏时，第一支撑件110/第二支撑件120与连接机构150成一特定角度，那么公轴171与母轴172也可以借助接合部176在特定角度处固定，使得柔性屏可 以以特定的角度固定。
最后如图7和图8所示，所述第三支撑件130通过转轴132而与第二支撑件120铰接，所述第三支撑件130在铰接部的径向边缘设置有相对的两个凹槽131，优选为球面型凹槽。对应地，所述第二支撑件120在与第三支撑件130的铰接部接触的部位设置有圆柱形凹槽122，所述圆柱形凹槽122内设置有弹簧160和钢珠161。当第三支撑件130旋转至与第二支撑件120处于同一水平面上时，所述圆柱形凹槽122内的弹簧160会将钢珠161的一部分挤压进其中一个凹槽131内；当第三支撑件130旋转至与第二支撑件120贴合时，所述圆柱形凹槽122内的弹簧160会将钢珠161的一部分挤压进另一个凹槽131内，当钢珠161的一部分嵌入凹槽131中时，所述钢珠起到卡位的作用，可以使第三支撑件130与第二支撑件120的相对位置关系保持稳定，并且当柔性屏完全展开时，第三支撑件130不会因重力作用而绕其转轴向下旋转。
本发明的工作原理是：
当第一支撑件110、第二支撑件120和第三支撑件130处于同一水平面上时，柔性屏140处于展开状态，此时柔性屏140具有最大的显示尺寸；
当第一支撑件110旋转至与第二支撑件120重合，同时第三支撑件130转至与第二支撑件120贴合时，柔性屏140处于完全收缩状态，此时柔性屏140部分置于第一支撑件与第二支撑件120的间隙中，柔性屏140位于第三支撑件130上的部分通过与第三支撑件130一起运动，转动至与第二支撑件120下表面相重合的平面，此时，只有位于第三支撑件130上的部分柔性屏140才能显示，柔性显示设备具有最小的显示尺寸，如图2所示。
本发明还提供一种具有上述柔性显示模组的电子装置。
本发明的有益效果是：
1.通过一次内折和一次外折，使得部分柔性屏140隐藏于装置内部，部分柔性屏140暴露于装置外部，相比于其他将全部柔性屏140隐藏于装置内部的结构，该结构可在此完全折叠的状态下提供时间日期，天气，来电提醒，备忘录等的显示功能，在只需查看时间日期，天气，接打电话的情况下，无需展开柔性显示组件，减少了不必要情况下柔性屏140的弯折，延长了柔性屏140的使用寿命。
2.通过该结构可以提供比单次折叠装置更大的显示尺寸，同时又能提供比多次折叠装置更薄的整体厚度。
虽然已经参考优选实施例对本发明进行了描述，但在不脱离本发明的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本发明并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
