 本发明的实施方式
以下各实施例的说明是参考附加的图示，用以例示本揭示可用以实施的特定实施例。本揭示所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本揭示，而非用以限制本揭示。在图中，结构相似的单元是用以相同标号表示。
下面结合附图和具体实施例对本揭示做进一步的说明：
本揭示实施例提供一种可折叠显示装置，下面结合图1至图10进行详细说明。
参考图1至图3，其中图1为本揭示实施例提供的可折叠显示装置的分解示意图，图2为本揭示实施例提供的可折叠显示装置在展平状态下的正面结构示意图，图3为本揭示实施例提供的可折叠显示装置在展平状态下的背面结构示意图。本揭示实施例提供的可折叠显示装置包括使可折叠显示装置处于折叠状态、半折叠状态和展平状态的可折叠机身11、用于进行画面显示的柔性显示面板12和用于模拟外接物理键盘手感的键盘膜13。
柔性显示面板12可采用现有技术中的柔性有机发光二极管显示面板，其可在可折叠机身11的作用下同步进行弯折或展开。柔性显示面板12包括显示区域121和位于显示区域121周围的非显示区域，显示区域121包括用于显示虚拟键盘（图中未示出）的虚拟键盘区域1211，虚拟键盘区域1211在不显示虚拟键盘的时候，可以同其他显示区域进行整面画面显示。
键盘膜13上设有多个与虚拟键盘的键位一一对应的凸出的按键131，虚拟键盘13与可折叠机身11的一端连接，并且可以相对于可折叠机身1进行翻转。键盘膜13在被使用时，可翻转至柔性显示面板12远离可折叠机身11的一侧，并与虚拟键盘区域1211贴合，按压任意一按键131，可使该按键131与对应的虚拟键盘的键位所在的柔性显示面板12的表面接触，从而完成对虚拟键盘键位的按压，因此无需外界物理键盘即可通过键盘膜131以及虚拟键盘的配合实现外接物理键盘的功能，还可以模拟外接物理键盘的手感，相对于仅只用虚拟键盘而言，可以提高可折叠显示装置的办公效率和使用体验。键盘膜13在未被使用时，可收纳于可折叠机身1远离柔性显示面板12的一侧，既不影响柔性显示面板12进行整面画面显示，也不影响可折叠机身进行弯折或展开，相对于外接物理键盘而言，可以提高带有键盘膜的可折叠显示装置的便携性。
具体地，键盘膜13上的每一个按键131均为中空结构，当按压其中任意一个按键131时，按键131凸出的部分下陷并与柔性显示面板12的上表面接触，当松开按键131时，按键131下陷的部分弹出并恢复原状，从而实现模拟外接物理键盘的手感。
进一步的，本揭示实施例所提供的柔性显示面板12为电容式触控结构的柔性显示面板，每一按键131的内表面均设有透明导电薄膜，当按压任一按键131时，位于内表面的金属导电薄膜与柔性显示面板12的上表面接触，金属导电薄膜与柔性显示面板12内部的触控感应电极之间形成电容并产生相应的触控信号，从而可以有效提高键盘膜13的触控灵敏度，避免由于键盘膜13的膜厚较大而使触控感应电极无法与手指形成电容造成触控失效的情况发生。
具体地，本揭示实施例中，所述键盘膜13的材料为透明热塑性聚氨酯弹性体橡胶（TPU），以此可以提供键盘膜13良好的形变恢复能力，并提升键盘膜13的键盘手感以及使用体验。当然，在一些实施例中，键盘膜13的材料还可以为其他透明弹性橡胶材料或者透明弹性硅胶材料，均可以获得与上述实施例相同的技术效果，具体材料可以根据实际需求进行选择，此处不做限制。
具体地，参照图1至图7，其中图4为本揭示实施例提供的可折叠显示装置在折叠状态下的正面结构示意图，图5为本揭示实施例提供的可折叠显示装置在折叠状态下的背面结构示意图，图6为本揭示实施例提供的可折叠显示装置在半折叠状态下的正面结构示意图，图7为本揭示实施例提供的可折叠显示装置在半折叠状态下的背面结构示意图。
显示区域121还包括第一显示区域1212和第二显示区域1213，第二显示区域1213设置于第一显示区域1212和虚拟键盘区域1211之间。可折叠机身11包括背板115、第一铰链110、第二铰链111以及分别与第一显示区域1212、第二显示区域1213和虚拟键盘区域1211对应的第一机身112、第二机身113以及第三机身114。背板115设置于第一机身112远离柔性显示面板12的一侧，第一机身112和第二机身113通过第一铰链110旋转连接，第二机身113与第三机身114通过第二铰链111旋转连接，可折叠显示装置可以通过第一铰链110进行弯折或者展开，以使可折叠显示装置处于如图2所示的展平状态或者如图4所示的折叠状态，可折叠显示装置也可以通过第二铰链111进行弯折或展开，以使可折叠显示装置处于如图6所示的半折叠状态。
进一步的，参照图5，键盘膜13与第三机身114远离第二机身113的一侧连接，第三机身114远离柔性显示面板12的一侧设有一容纳腔1141，键盘膜13在未被使用时可以收纳于该容纳腔1141内。
在本揭示实施例中，键盘膜13与第三机身114远离第二机身113的一侧通过双面胶固定连接，键盘膜13可相对于固定连接的一端进行翻转。在其他一些实施例中，键盘膜13还可以通过转轴与第三机身114远离第二机身113的一侧旋转连接，键盘膜13可以通过转轴进行翻转。
具体地，可折叠显示装置具有笔记本模式和平板模式两种工作模式。当可折叠显示装置处于平板模式时，可折叠显示装置处于如图2和图3所示的展平状态，第一显示区域212与第二显示区域213以及虚拟键盘区域211处于同一平面，并进行整面画面显示。第一机身112、第二机身113以及第三机身114通过第一铰链110和第二铰链111的作用也处于同一平面，键盘膜13收纳于第三机身114远离柔性显示面板12的一侧的容纳腔1141内，不影响可折叠显示装置在平板模式下的正常使用。当然，在平板模式下，若要使用键盘膜13，同样可以将键盘膜13翻转至柔性显示面板12远离可折叠机身11的一侧并与虚拟键盘区域1211贴合，以此搭配虚拟键盘区域1211显示的虚拟键盘进行使用。
当可折叠显示装置处于笔记本模式时，可折叠显示装置处于如图6和图7所示的半折叠状态，第一显示区域1212和第二显示区域1213在第一机身112、第二机身113以及第一铰链110的支撑作用下处于同一平面，同时通过第二铰链12相对站立于第三机身114所在的平面并进行画面显示，虚拟键盘区域1211则显示虚拟键盘。在笔记本模式下，第一机身112和第二机身113与第三机身114所在平面之间的夹角介于0~180度之间，该夹角可以通过第二铰链111进行调整并固定，以此使处于笔记本模式的可折叠显示装置可以在多种不同开合角度下进行使用。键盘膜13翻转至柔性显示面板12远离可折叠机身11的一侧，并与虚拟键盘区域1211贴合，以此搭配虚拟键盘区域1211显示的虚拟键盘进行使用，相对于只是用虚拟键盘而言，不仅可以利用键盘膜模拟外接物理键盘的手感，还可以有效提高可折叠显示装置在笔记本模式下的办公效率。当然，在笔记本模式下，如不需要使用键盘膜13，同样可以将键盘膜13收纳于第三机身114的容纳腔1141内，并不影响可折叠显示装置在笔记本模式下的站立以及使用。
进一步的，第二显示区域1213和虚拟键盘区域1211形成的一整体与第一显示区域1212相对于第一铰链110对称。可折叠显示装置通过第一铰链110弯折至如图4和图5所示的折叠状态时，第一显示区域1212与第二显示区域1213和虚拟键盘区域1211相对向内弯折，并且边缘的部分相互重合，第二机身113、第三机身114与第一机身112位于柔性显示面板12的外侧，同时也相对向内弯折并且边缘的部分相互重合，此时为可折叠显示装置能够折叠的最小形态，便于可折叠显示装置的携带。
更进一步的，第二显示区域1213和虚拟键盘区域1211相对于第二铰链111对称。处于笔记本模式时，可折叠显示装置处于半折叠状态，用于显示虚拟键盘的虚拟键盘区域1211仅占柔性显示面板12的显示区域121的四分之一，用于进行画面显示的第一显示区域1212和第二显示区域1213即可占据显示区域121的四分之三，相较于现有内折的可折叠显示装置，可以有效增大笔记本模式下用于进行画面显示的显示区域的面积，以此提升笔记本模式下可折叠显示装置的使用体验，并提高可折叠显示装置的办公效率。
进一步的，参照图6和图7，第二机身113远离柔性显示面板12的一侧设有支架116。处于笔记本模式时，支架116打开，支架116的一端抵持于第三机身114所在的平面，支架116的另一端抵持于第二机身113的背面，用以支撑第一机身112和第二机身113，以使其保持在固定的角度并防止其由于重心过高而发生倾倒。第二机身113远离柔性显示面板12的一侧同样设有一容纳腔，处于平板模式或者折叠状态下时，支架116可以收纳于第二机身113的容纳腔内，不影响可折叠显示装置的弯折或者展开，从而可以在提高可折叠显示装置在笔记本模式下的稳定性的同时，还可以提高可折叠显示装置的便携性。
当然，支架116不仅限设置于第二机身113远离柔性显示面板12的一侧，在一些实施例中，支架116同样也可以设置于第一机身112远离柔性显示面板12的一侧，以此也可以获得与上述实施例相同的支撑效果。在另一些实施例中，也可以通过外置独立的支架取代设置于第二机身远离柔性显示面板一侧的支架116，同样可以实现与上述实施例相同的支撑效果，具体结构可以根据实际需求进行设定，此处不做限制。
更进一步的，参照图8至图10，图8为本揭示实施例提供的可折叠显示装置在半折叠状态下的底面结构示意图，图9为图8中a部分的放大示意图，图10为图8中b部分的放大示意图。支架116一侧的两端设有轴孔，支架116通过转轴117与第二机身113靠近第一机身112的一侧旋转连接，转轴117上设有扭簧118，扭簧118的两侧扭臂分别固定于支架116和第二机身112上。
第二机身113靠近第三机身114的一侧设有滑动卡扣119，滑动卡扣119的底座通过螺栓固定于第二机身113上，滑动卡扣用于固定和释放支架116。处于笔记本模式时，波动滑动卡扣119，支架116可以在扭簧118的作用下弹出，用以支撑所述可折叠显示装置；处于平板模式或者处于折叠状态下，支架116收纳于第二机身113远离柔性显示面板12一侧的容纳腔内，并通过滑动卡扣119进行固定，以防止支架116弹出。
在本揭示实施例中，可折叠显示装置还应包括处理器、驱动芯片以及电源组件等零部件，处理器、驱动芯片以及电源组件等零部件可以设置于第一机身112、第二机身113或者第三机身114内，位于不同机身内的各零部件之间可以通过柔性印刷电路板进行连接，柔性显示面板12同样通过柔性印刷电路板与上述各零部件进行连接。
有益效果：本揭示实施例通过将键盘膜与可折叠机身的一侧连接，键盘膜上设有与虚拟键盘的键位一一对应的凸起的按键，键盘膜在未使用时可收纳于可折叠机身远离柔性显示面板的一侧，不影响可折叠显示装置在平板模式下的正常使用，键盘膜在使用时可翻转至柔性显示面板远离可折叠机身的一侧并与柔性显示面板的虚拟键盘区域贴合以此实现模拟外接物理键盘手感的功能，从而提高可折叠显示装置在笔记本模式下的办公效率以及可折叠显示装置的便携性。
综上所述，虽然本揭示以优选实施例揭露如上，但上述优选实施例并非用以限制本揭示，本领域的普通技术人员，在不脱离本揭示的精神和范围内，均可作各种更动与润饰，因此本揭示的保护范围以权利要求界定的范围为基准。
