可以理解的是，如果没有设置该活动空间，柔性屏组件200在运动过程中可能会与壳体组件100接触并产生摩擦，进而造成柔性屏组件200的损坏；如果直接在柔性屏组件200的周围设置间隙，使得柔性屏组件200与壳体组件100隔离，会造成壳体组件100空间的浪费，且从外观面上需要设置额外的遮 挡部件对壳体组件100和柔性屏组件200之前的间隙进行遮挡，这无疑会增加壳体组件100的体积。而本申请实施例通过将壳体组件100分离成主体部110和活动部120，在柔性屏组件200运动时，可使活动部120处于第二状态，此时活动部120与柔性屏组件200之间具有一定距离，然后再进行柔性屏组件200的运动，这样可以直接避免柔性屏组件200的伸缩动作与壳体组件100发生摩擦风险，进而可以减少柔性屏组件200运动过程中的磨损，柔性屏组件200的使用寿命，在完成伸缩动作，可以将活动部120与主体部110连接，使得从外观面看不到该活动空间，也可以避免其他的物体通过该活动空间进入壳体组件100内部。
请参阅图3、图4以及图5，图3为图2所示的电子设备沿P1-P1方向的剖面结构示意图，图4为图2所示的电子设备沿P2-P2方向的剖面结构示意图，图5为图2所示的电子设备沿P3-P3方向的剖面结构示意图。活动部120可以通过连接件诸如连接件300与主体部110可活动连接。比如主体部110可以包括第一侧边诸如第一侧边111和第二侧边诸如第二侧边112，第一侧边111与第二侧边112相对设置，比如第一侧边111位于电子设备20的顶部或者说电子设备20的显示区域的顶部，第二侧边112位于电子设备20的底部或者说电子设备20的显示区域的底部。
其中，第一侧边111设置有相互连通的第一滑槽1111和第一限位槽1112。连接件300可以包括第一连杆310和第一滑块320，第一连杆310与活动部120(比如活动部120的一端)连接，且第一连杆310容置在第一滑槽1111内，第一连杆310可以在第一滑槽1111内滑动，使得活动部120可以在第一状态和第二状态之间转换；第一滑块320容置在第一限位槽1112内，第一滑块320的尺寸小于第一滑槽1111的尺寸，以限制第一滑块320在第一限位槽1112内活动而无法运动至第一滑槽111内，进而限制活动部120的运动距离。
第一滑块320可以通过弹性件诸如弹簧与第一限位槽1112的槽壁连接，弹性件可以产生弹性形变，使得第一滑块320与弹性件之间具有预紧力，进而使得活动部120在第二状态或第一状态下有一定的预紧力，可以提高用户使用活动部120的体验感。为了使得活动部120可以在活动状态和第一状态保持住，本申请实施例在第一滑块320设置有第一限位件，第一限位槽1112的槽壁设置有第二限位件，第一限位件可以跟第二限位件配合以限位住第一滑块320，使得第一滑块320保持在预设位置上，进而使得活动部120保持在第一状态或第二状态。
例如，第一滑块320可以为长方体结构，第一滑块320包括相互连接的第一侧边、第二侧边、第三侧边和第四侧边，第一侧边和第三侧边相对设置，第二侧边和第四侧边相对设置，第一限位件可以设置在第一侧边，第二侧边可以与第一连杆310连接，第四侧边可以与弹性件连接。其中第一限位件可以为卡槽，比如第一侧边包括底壁、第一侧壁和第二侧壁，底壁与侧壁连接以形成所述卡槽，其中第一侧壁和第二侧壁相互倾斜设置，底壁连接在第一侧壁和第二侧壁之间。第一限位槽1112的槽壁上的第二限位件可以为卡接件，该卡接件可以卡设在所述卡槽内以固定第一侧边。其中，卡接件可以为弹片，卡接件的外表面为弧形面以为卡接件提供形变空间。
当活动部120朝远离主体部110的方向运动时，活动部120会拉动第一连杆310和第一滑块320也朝远离主体部110的方向运动，第一滑块320在运动过程中，卡接件的外表面发生弹性形变，并从卡槽的底壁位置沿着第一侧壁滑出卡槽外部，使得第一滑块320的第一侧边可以脱离卡槽，进而使得活动部120可以与主体部110分离一段距离以使活动部120和主体部110之间具有活动空间。当活动部120朝靠近主体部110的方向运动时，活动部120会推动第一连杆310和第一滑块320也朝靠近主体部110的方向运动，第一滑块320在运动过程中，卡接件的外表面发生弹性形变，并沿着卡槽的第一侧壁滑入至底壁位置，第二侧壁可以对卡接件进行限位，以将卡接件卡设在卡槽内。
需要说明的是，第一限位件也可以设置在第三侧边上，或者第一侧边和第三侧边可以同时都设置有第一限位件。此外，第一滑块320的结构并不限于长方体结构，比如第一滑块320也可以为球状结构或者其他的多边体结构等。
第二侧边112可以设置有相互连通的第二滑槽和第二限位槽。连接件300可以包括第二连杆和第二滑块，第二连杆与活动部120连接(比如活动部120的另一端)，且第二连杆容置在第二滑槽内，第二 连杆可以在第二滑槽内滑动，使得活动部120可以在第一状态和第二状态之间转换；第二滑块容置在第二限位槽内，第二滑块的尺寸小于第二滑槽的尺寸，以限制第二滑块在第二限位槽内活动而无法运动至第二滑槽内，进而限制活动部120的运动距离。其中，第二滑槽可以与第一滑槽1111的结构相同，第二限位槽可以与第一限位槽1112的结构相同，第二连杆可以与第一连杆3110的结构相同，第二滑块可以与第一滑块320的结构相同。当然，第二滑槽也可以与第一滑槽1111的结构不同，第二限位槽也可以与第一限位槽1112的结构不同，第二连杆也可以与第一连杆310的结构不同，第二滑块也可以与第一滑块320的结构不同。
本申请实施例还可以在第二滑块设置有第三限位件，第二限位槽的槽壁设置有第四限位件，第三限位件可以跟第四限位件配合以限位住第二滑块，使得第二滑块保持在预设位置上，进而使得活动部120保持在第一状态或第二状态。第三限位件的结构可以与第一限位件的结构相同，第四限位件的结构可以与第二限位件的结构相同。当然，第三限位件的结构与第一限位件的结构不同、第四限位件与第二限位件的结构不同也是可以的。
请继续参阅图3，电子设备20还可以包括密封件诸如密封件400，密封件400设置在活动部120的内表面，其中活动部120的内表面指的是活动部120靠近柔性屏组件200的一面。密封件400可以由泡棉材料、橡胶材料或者其他材料制成。当活动部120处于第一状态时，密封件400可以与柔性屏组件200抵接以在活动部120处于第一状态时，封堵住活动部120与柔性屏组件200之间的缝隙，进而起到密封防尘及部分水汽的作用。
请继续参阅图3和图5，轴500可以设置在主体部110上，轴500设置在第一侧边111和第二侧边112之间，比如轴500的一端与第一侧边111连接，轴500的另一端与第二侧边112连接。柔性屏组件200套设在轴500上且柔性屏组件200可以沿着轴500的外表面运动，其中轴500位于柔性屏组件200的非显示面一侧，活动部120位于柔性屏组件200的显示面一侧。可以理解的是，柔性屏组件200在沿轴500的外表面运动的过程中，可以先使得活动部120处于第二状态，再使得柔性屏组件200沿着轴500的外表面运动，进而使得柔性屏组件200的显示面不会因为直接与活动部120直接接触摩擦而损坏。
其中，活动部120在柔性屏组件200上的投影与轴500在柔性屏组件200上的投影至少部分重叠。活动部120在柔性屏组件200上的投影指的是投影方向为平行于主体部110时的投影，轴500在柔性屏组件200上的投影指的是投影方向为平行于主体部110时的投影。可以理解的是，柔性屏组件200套设在轴500上时，柔性屏组件200会形成一个弯折区域，活动部120位于该弯折区域对应的位置上。而且，活动部120的外表面与主体部分211的外表面齐平，比如活动部120位于电子设备20的显示面的部分与主体部分211的显示面其齐平，可以提高电子设备的外观美感。需要说明的是，活动部120也可以位于柔性屏组件200的非弯折区域。
如图3所示，本申请实施例的柔性屏组件200可以包括柔性显示模组210和柔性支撑件220，柔性支撑件220位于柔性显示模组210的非显示面一侧，用于支撑柔性显示模组210。可以理解的是，柔性支撑件220的结构强度较高，一方面可以支撑柔性显示模组210，提高柔性显示模组210的平整性，使得柔性显示模组210在显示过程不易塌陷或者说褶皱，另一方面柔性支撑件220还可以提高柔性屏组件200的整体强度，可以保护柔性屏组件300在拉伸过程中不易损坏。其中，柔性显示模组210可以为OLED(Organic Light Emitting Diode有机发光二极管)模组，该OLED模组可包括显示基板和封装材料，显示基板和封装材料中间封装有机发光物，该OLED模组上包括若干OLED单元，每个OLED单元与电子设备的主板电性连接，以实现自发光，显示画面。柔性显示模组210也可以为LCD(Liquid Crystal Display液晶显示器)模组，该LCD模组可包括显示基板和封装材料，在显示基板和封装材料中间封装有液晶材料，电子设备的主板为液晶材料提供电压，从而改变液晶分子的排列方向，背光源投射出的光经由LCD模组内部共同作用后，在显示区域形成图像，以显示画面。
结合图6所示，图6为本申请实施例提供的电子设备的第二种结构示意图。柔性屏组件200可以包括如图1所示的窄屏模式和如图6所示的宽屏模式，窄屏模式下，柔性屏组件200的显示面积固定；宽屏模式下，柔性屏组件200的显示面积可扩展。比如，柔性显示模组210可以包括主体部分211和扩展 部分212，主体部分211与壳体组件100固定连接，扩展部分212与轴诸如轴500抵接且扩展部分212可沿着轴500的外表面运动，使得扩展部分212可展开于壳体组件100外或回收于壳体组件100内。
当柔性屏组件200处于窄屏模式或宽屏模式时，主体部分211始终固定在壳体组件100的外表面，以裸露在电子设备20的外部，此时扩展部分212处于收纳状态，此时扩展部分212隐藏在壳体组件100的内部，无法用于显示信息，仅通过柔性屏组件200的主体部分211进行显示；当柔性屏从窄屏模式切换到宽屏模式时，用户可以拉动活动部120朝远离主体部110的方向运动(或者可以设置驱动机构驱动活动部120运动)，再驱动扩展部分212的至少一部分沿着轴500的外表面逐渐转动出壳体组件100外部，此时扩展部分212的至少一部分裸露在壳体组件100的外部，实现窄屏模式切换至宽屏模式。裸露在外部的扩展部分212可以与主体部分211一起显示信息，相对于仅使用主体部分211信息显示，可以增加显示面积。当柔性屏组件200从宽屏模式切换到窄屏模式时，可以使扩展部分212朝靠近壳体组件100的方向沿轴500的外表面逐渐转动进壳体组件100的内部(可以通过手动驱动的方式，也可以通过机械驱动的方式实现柔性屏组件200的展开或收纳)，使得扩展部分212的至少一部分收纳进壳体组件100内，当完成切换之后，再推动活动部120朝靠近主体部110的方向运动，使得活动部120与主体部110连接(或者也可以通过机械驱动的方式驱动活动部120的往复运动)。
柔性支撑件220可以包括软胶连接带、金属片等。例如图7所示，图7为图1所示的电子设备的部分结构示意图。柔性支撑件220可以包括软胶连接带诸如软胶连接带221，软胶连接带221的硬度(邵尔A)为(60～75)度，比如65度、68度、70度或75度等。软胶连接带221可以采用橡胶、硅胶和TPU(Thermoplastic polyurethanes，热塑性聚氨酯弹性体橡胶)等。软胶连接带221设置在扩展部分212的非显示面，软胶连接带221可以为扩展部分212提供一个平整的承载面，使得扩展部分212可以平整地展开，不出现褶皱或凹陷的不良现象。而且相对于刚性材料，本申请实施例采用的软胶连接带221的硬度为在60度至75度之间，可以降低软胶连接带221运动过程中对扩展部分212的损坏，进而保护扩展部分212与软胶连接带221的接触面不易磨损。此外，由于扩展部分212在运动过程中，会经常与轴500产生摩擦进而使得扩展部分212容易破损。而本申请实施例通过在需要运动的扩展部分212增设软胶连接带221，可以将原本作用于扩展部分212的摩擦力转移到软胶连接带221上，可以进一步地保护扩展部分212。
如图8所示，图8为图7所示电子设备中柔性屏组件和轴的第一种局部结构示意图，软胶连接带221的尺寸等于扩展部分212的尺寸，软胶连接带221在柔性屏组件200上的投影位于扩展部分212，使得软胶连接带221可以覆盖整个扩展部分212的非显示面，进而保护整个扩展部分212。相对于相关技术中，直接将柔性屏作为拉伸主体，本申请在扩展部分212设置软胶连接带221，可以间隔扩展部分212与轴500直接接触，进而避免扩展部分212的非显示面直接与轴500的外表面相互摩擦过程中对扩展部分212造成的磨损。
在其他一些实施例中，比如图9所示，图9为图7所示电子设备中柔性屏组件和轴的第二种局部结构示意图。软胶连接带221的尺寸也可以大于扩展部分212的尺寸。当软胶连接带221的尺寸大于扩展部分212的尺寸时，软胶连接带221在柔性屏组件200上的投影，一部分位于扩展部分212，一部分位于扩展部分212外，比如可以位于主体部分211上，也可以位于壳体组件100的容置空间内，比如可以用于连接驱动电机，驱动电机通过驱动软胶连接带221中位于壳体组件100的容置空间内的部分进行卷曲或者舒展来驱动扩展部分212展开或者回收。
当软胶连接带221的一部分位于主体部分211时，软胶连接带221的侧部外表面与主体部分211的侧部外表面齐平。比如，软胶连接带221和主体部分211均为长方体结构，软胶连接带221可以具有四个相互连接的侧部，且软胶连接带221具有两个相对的表面，两个表面连接在四个侧部的两侧以围设形成长方体结构。同样地，主体部分211也可以具有四个相互连接的侧部以及相对的显示面和非显示面，其中软胶连接带221设置在主体部分211的非显示面，软胶连接带221的四个侧部外表面与主体部分211的四个侧部外表面齐平，软胶连接带221可以对主体部分211起到支撑作用，使得主体部分211的显示面更平整，而且从外界也观察不到软胶连接带221，保持柔性屏组件200的外观简洁性。
如图10至图14所示，图10为图7所示电子设备中柔性屏组件的第一种结构示意图，图11为图10 所示柔性屏组件中第一支撑片的结构示意图，图12为图10所示第一支撑片的局部结构示意图，图13为图11所示第一支撑片沿P4-P4的剖面结构示意图，图14为图11所示第一支撑片沿P5-P5的剖面结构示意图。
柔性支撑件220还可以包括第一支撑片诸如第一支撑片222，第一支撑片222可以采用金属材料制成，比如第一支撑片可以为钢片、铝片、铜片等。第一支撑片222嵌入设置在软胶连接带221的内部，比如可以采用在第一支撑片222注塑成型出软胶连接带221的方式，使得第一支撑片222包裹在软胶连接带221的内部，进而使得第一支撑片222不直接与柔性屏组件200接触，达到保护柔性屏组件200的目的。
初始状态下，第一支撑片222处于第一状态，第一状态为第一支撑片222的至少一部分未与扩展部分212接触的状态，当软胶连接带221跟扩展部分212一起运动至轴500的表面时，轴500和第一支撑片222之间会产生沿轴500的径向的相互作用力，使得第一支撑片222从第一状态切换至第二状态，第二状态为第一支撑片222完全贴合于扩展部分212的状态；当软胶连接带221跟扩展部分212一起继续运动时，软胶连接带221与扩展部分212逐渐远离轴500的表面，轴500和第一支撑片222之间的相互作用力逐渐消失，此时第一支撑片222逐渐恢复原状，即第一支撑片222从第二状态切换为第一状态。
其中，当第一支撑片222处于第一状态时，第一支撑片222的一部分未与扩展部分212接触，比如可以是第一支撑片222的中间具有凹陷结构，第一支撑片222的两侧与扩展部分212接触，第一支撑片222的中间与扩展部分212具有间隙；还可以是第一支撑片222具有多个凹陷结构，第一支撑片222在具有凹陷结构的部分与扩展部分212具有间隙，第一支撑片222的其他部分与扩展部分212接触或者说贴合扩展部分212的非显示面接触。当第一支撑片222处于第二状态时，由于第一支撑片222接收到沿轴500的径向的作用力，使得第一支撑片222产生形变，进而使得原先第一支撑片222未与扩展部分212接触的一部分贴合到扩展部分212的显示面上，进而使得第一支撑片320的外形与扩展部分212的外形一致，从而保证柔性屏组件200可以按照预设运动轨迹反复展开和回收。
例如，第一支撑片222可以包括第一侧部2221、第二侧部2222和凹陷部2223，凹陷部2223位于第一侧部2221和第二侧部2222之间，第一侧部2221位于轴500的一端端部，第二侧部2222位于轴500的另一端端部，凹槽部513位于轴500的中间位置。其中凹陷部2223从主体部分211的显示面朝主体部分211的非显示面方向弯曲形成。可以理解的是，第一支撑片222的结构类似于卷尺的结构，第一支撑片222在沿电子设备20的宽度方向的横截面为弧形结构、且第一支撑片222的弯曲方向背向轴500。当软胶连接带221沿轴500的外表面运动的过程中，第一支撑片222可发生形变以使凹陷部2223在第一弯曲状态和第二弯曲状态之间切换。
例如，初始状态下，凹陷部2223处于第一弯曲状态，第一弯曲状态指的是凹陷部2223从主体部分211的显示面朝主体部分211的非显示面方向弯曲。当软胶连接带221沿轴500运动的过程中，运动至轴500位置的软胶连接带221会与轴500抵接，在这个过程中，位于软胶连接带221内部的第一支撑片222可以通过软胶连接带221接收到沿轴500的径向的作用力并产生形变，使得凹陷部2223从第一弯曲状态切换为第二弯曲状态，其余未与轴500抵接的第一支撑片的部分保持原状，即处于第一弯曲状态。其中，第二弯曲状态指的是凹陷部2223从主体部分211的非显示面朝主体部分211的显示面方向弯曲，使得第一支撑片222的弯曲方向与轴500的弧度相同，进而提高软胶连接带221与轴500的贴合程度，使得软胶连接带221的运动更平稳。当软胶连接带221沿着轴500的外表面方向逐渐运动到壳体组件100外或壳体组件100内时，原先与轴500抵接的软胶连接带逐渐远离轴500，此时轴500对第一支撑片222的挤压作用力也会逐渐撤销，进而使得凹陷部2223从第二弯曲状态切换为第一弯曲状态。
可以理解的是，第一支撑片222在展平状态下，第一支撑片222的截面形状如图13所示，第一支撑片222在展平状态下是呈凹陷状，只需用一点力顶其背面，则可发生形变翻转成平直状，使得第一支撑片222的形状与扩展部分212的形状相同，进而使得扩展部分212可沿着轴500的表面运动。基于该第一支撑片222的结构，使得第一支撑片222在接收到沿轴500的径向的作用力时即可发生形变，从凹陷状翻转为平直状，如图14所示；并在未接收到沿轴500的径向的作用力后恢复原先的凹陷状。
需要说明的是，第一支撑片222的结构并不局限于此，比如第一支撑片222可以具有多个凹陷部2223，多个凹陷部2223间隔设置，一个凹陷部2223从主体部分211的显示面朝主体部分211的非显示面方向弯曲形成，当扩展部分运动至轴500上时，全部或部分凹陷部2223接收到沿轴500的径向的作用力时产生形变，以使凹陷部2223从主体部分的非显示面朝主体部分的显示面方向弯曲，此时多个凹陷部2223从第一弯曲状态切换至第二弯曲状态。当扩展部分212远离轴500时，凹陷部2223恢复至从主体部分211的显示面朝主体部分320的非显示面方向弯曲的状态。
可以理解的是，如果第一支撑片222为普通的平直状的刚性结构时，当第一支撑片222运动到轴500的位置时，由于轴500与第一支撑片222之间的相互作用力，会使得第一支撑片222变形为弯折状态进而使得第一支撑片222贴合轴500的外表面，当第一支撑片222离开轴500的位置时，此时轴500与第一支撑片222之间的相互作用力消失，但由于第一支撑片222为平直状的刚性结构，其变形后没有其他作用力的作用下，并无法恢复原始的平直状，比如会呈现原先的弯折状态，从而也会使得扩展部分212呈现不平整的情况，影响电子设备20的显示效果。而本申请的第一支撑片222可以在第一状态和第二状态之间切换，使得在轴500的位置时(或者说弯折位置时)从第一状态切换至第二状态，运动到其他位置时又从第二状态切换回第一状态，即可以实现扩展部分212在展开状态和回收状态的自由切换，又可以使得扩展部分212在展开状态和回收状态均保持平整，减少扩展部分212运动过程对电子设备20的显示效果的影响。
在其他一些实施例中，也可以直接将第一支撑片222设置在扩展部分212的非显示面。第一支撑片222可以采用双面胶或胶水等粘接剂直接粘接到扩展部分212的非显示面上。
当扩展部分212位于壳体组件100内时，第一支撑片222的一部分与轴500抵接。比如扩展部分212的一部分与轴500的表面抵接，扩展部分212的一部分与轴500之间具有间隙(可以理解成扩展部分212的一部分不挨着轴500)，此时第一支撑片222的一部分与轴500抵接，第一支撑片222的另一部分与轴500具有间隙。需要说明的是，第一支撑片222的结构并不限于此，比如第一支撑片222可以只设置在与轴500之间具有间隙的扩展部分212的那一部分上，而不设置在与轴500抵接的扩展部分212的另一部分上，此时第一支撑片222与轴500间隔设置，其与轴500不抵接。
当扩展部分212位于壳体组件100外时，第一支撑片222的一部分与轴500抵接。比如扩展部分212的一部分与轴500的表面抵接，扩展部分212的一部分与轴500之间具有间隙(可以理解成扩展部分212的一部分不挨着轴500)，此时第一支撑片222的一部分与轴500抵接，第一支撑片222的另一部分与轴500具有间隙。可以理解的是，此时扩展部分212的一部分平铺在壳体组件100外，扩展部分212的一部分套在轴500的表面。需要说明的是，第一支撑片222的结构并不限于此，比如当扩展部分212位于壳体组件100外时，第一支撑片222可以只设置在与轴500之间具有间隙的扩展部分212的那一部分上，而不设置在与轴500抵接的扩展部分212的另一部分上，此时第一支撑片222与轴500间隔设置，其与轴500不抵接。
第一支撑片222的尺寸可以大于或等于扩展部分212的尺寸，当第一支撑片222的尺寸等于扩展部分212的尺寸时，第一支撑片222在柔性屏组件200上的投影位于扩展部分212，使得第一支撑片222可以覆盖整个扩展部分212的非显示面，进而支撑整个扩展部分212。相对于相关技术中，直接将柔性屏作为拉伸主体，本申请实施例在扩展部分212设置第一支撑片222，可以间隔扩展部分212与轴500直接接触，进而避免扩展部分212的非显示面直接与轴500的外表面相互摩擦过程中对扩展部分212造成的磨损。当第一支撑片222的尺寸大于扩展部分212的尺寸时，第一支撑片222在柔性屏组件200上的投影，一部分位于扩展部分212，一部分位于扩展部分212外，比如可以位于主体部分211上，也可以位于壳体组件100的容置空间内。
当第一支撑片222的一部分位于主体部分211时，第一支撑片222的侧部外表面与主体部分211的侧部外表面齐平。比如，第一支撑片222和主体部分211均为长方体结构，第一支撑片222可以具有四个相互连接的侧部，且第一支撑片222具有两个相对的表面，两个表面连接在四个侧部的两侧以围设形成长方体结构。同样地，主体部分211也可以具有四个相互连接的侧部以及相对的显示面和非显示面， 其中第一支撑片222设置在主体部分211的非显示面，第一支撑片222的四个侧部外表面与主体部分211的四个侧部外表面齐平，第一支撑片222可以对主体部分211起到支撑作用，使得主体部分211的显示面更平整，而且从外界也观察不到第一支撑片222，保持柔性屏组件200的外观简洁性。
需要说明的是，第一支撑片222也可以不位于主体部分211上，比如图15所示，图15为本申请实施例提供的第一支撑片和第二支撑片的第一种局部结构示意图，柔性支撑件220还可以包括第二支撑片223，第二支撑片223位于主体部分211的非显示面。第二支撑片223的结构与第一支撑片222的结构不同，比如第二支撑片223为平直结构，其并不具有弧形结构，第二支撑片223可以为主体部分211提供平整的承载面。需要说明的是，第二支撑片223的结构可以与第一支撑片222相同，可便于加工。
可以理解的是，为实现柔性屏显示模组210在拉伸弯折区，其柔性屏显示模组210能按弯折形状源源不断由展平到弯折，又从弯折到展平状态，显然能实现这两种状态转变的材料一般是柔性材料，并且要求材料必须处于拉伸状态，如柔性屏显示模组210中的各层薄膜材料，但若只有柔性材料，在拉缩弯折部分，其一端在拉伸状态下，柔性材料无法按既定弯折轨迹进行抽拉。并且柔性屏显示模组210在拉伸状态下是不能直接受力的，因为这样很容易导致柔性屏显示模组210损坏。显然，要实现柔性屏显示模组210在折弯位置按既定轨迹实现伸缩，并且保证柔性屏显示模组210不单独受力，因此在折弯区需要增加附着刚性结构，但若采用一般的刚性结构是无法实现展平及弯折重复切换的。而本申请实施例通过对第一支撑片222的结构进行改进，使得第一支撑片222可以在第一弯曲状态和第二弯曲状态切换，进而使得柔性屏可轻松地在展开状态和回收状态之间切换。
需要说明的是，第一支撑片222的结构并不局限于此，比如第一支撑片222可以在电子设备20的宽度方向上产生形变，使得第一支撑片222在轴500的外表面运动的过程中可以被拉伸，从而保证第一支撑片222在伸缩折弯区能够轻松实现对扩展部分212的支撑且在沿轴500外表面运动过程中可以实现伸缩折弯而不出现损坏风险。可以理解的是，如果直接在扩展部分212的非显示面设置刚性片，刚性片运动到轴500位置时可能会出现张力不足而断裂损坏的情况。而如果直接采用橡胶件或弹簧式的弹性件，可能会因为弹性过大而导致对扩展部分212的支撑力度不足，进而导致柔性屏组件200出现褶皱或凹陷的不良现象产生。
例如，如图16所示，图16为本申请实施例提供的第一支撑片和第二支撑片的第二种局部结构示意图。第一支撑片222的全部或一部分设置有多个网孔诸如网孔2224以提高第一支撑片222的可形变能力，比如可以采用酸性蚀刻液对第一支撑片222进行蚀刻，以在第一支撑片222上蚀刻出多个菱形的网孔2224，使得第一支撑片222呈菱形丝网结构，菱形丝网结构可以使得第一支撑片222在电子设备20的宽度方向和/或长度方向具有可拉伸的能力。当第一支撑片222在电子设备20的宽度方向上运动时，第一支撑片222会接收到轴500施加的挤压作用力和沿电子设备20的宽度方向的拉力，其在挤压作用力和拉力的作用下可以发生形变，相对于刚性片而言，本申请实施例的第一支撑片222可以保证在运动过程中不会因为张力过大而断裂。
网孔2224可以为规则形状，比如为菱形结构，矩形结构等，网孔2224也可以为不规则形状。比如，本申请实施例的网孔2224为菱形结构，比如可以使得第一支撑片222的全部或一部分形成菱形丝网结构，具有菱形丝网结构的第一支撑片222的优势在于柔韧度非常好，并且在保证柔性屏组件模组的平整度具有非常大的优势，其弯折寿命长。
其中，当第一支撑片222的尺寸等于扩展部分212的尺寸时，可以将第一支撑片222均加工成菱形丝网结构；当第一支撑片222的尺寸大于扩展部分212的时候，可以将第一支撑片222位于扩展部分212的非显示面的部分加工成菱形丝网结构，第一支撑片222的其他部分为平整的刚性片结构，无需采用蚀刻液进行蚀刻，比如第一支撑片222位于主体部分211的非显示面的部分。可以理解的是，第一支撑片222可以包括第一段和第二段，其中第一段设置在主体部分211的非显示面，第一段为完整的刚性片结构，表面无网孔设计，第二段设置在扩展部分212的非显示面，第二段设置有多个网孔320，网孔320为菱形结构，以使得第二段形成菱形丝网结构。由于在第一支撑片222的运动过程中，主要是位于扩展部分212的非显示面的第一支撑片222部分受力，只将第一支撑片222的一部分加工成菱形丝网结构， 一方面保证第一支撑片222的可形变能力，另一方面又可以保证整个第一支撑片222的支撑力度，而且还可以降低制造的难度和成本。
结合图17所示，图17为图7所示电子设备中柔性屏组件的第二种结构示意图，柔性屏组件200还可以包括保护层诸如保护层224，保护层224可以为PI(PolyimideFilm，聚酰亚胺薄膜)膜。当然保护层224也可以为其他材料制成的膜层结构，比如PET(Polyethylene terephthalate，聚对苯二甲酸乙二醇酯)膜、PE(Polyethylene，聚乙烯)膜等。第一支撑片222夹设在两个保护层224之间，且保护层224覆盖在网孔2224上以封堵网孔2224，使得设置在第一支撑片222上的物体(比如双面胶、胶水等粘接剂)不会通过网孔2224渗透入其他部件上。比如第一支撑片222可以包括相对设置的第一侧面和第二侧面，第一侧面为靠近柔性屏组件200的非显示面的一面，第二侧面为远离柔性屏组件200的一面。其中第一侧面设置有第一保护层2241，第一保护层2241盖设在网孔2224上以从第一侧面朝第二侧面的方向封堵网孔2224；第二侧面设置有第二保护层2242，第二保护层2242盖设在网孔2224上以从第二侧面朝第一侧面的方向封堵网孔2224，进而使得设置在第一支撑片222(包括第一侧面和第二侧面)的物体(比如双面胶、胶水等粘接剂)不会通过网孔2224渗透到柔性屏组件200、或者中框、或者滑动件。
本申请实施例通过设置可拉伸的第一支撑片222，不但可以增加拉伸强度，而且还可以减小了柔性屏组件200的破坏风险，延长柔性屏组件200的使用寿命。
请继续参阅图7，轴500可以为圆柱体结构，且轴500的外表面还设置有第一限位结构诸如第一限位结构，第一限位结构可以为围绕轴500的外表面周缘设置的环形结构。第一限位结构的数量可以为多个，多个第一限位结构间隔设置，第一限位结构的数量也可以为一个。第一限位结构可以为设置在轴500的外表面并凸出于轴500的外表面的凸出结构，第一限位结构也可以为设置在轴500的外表面的凹槽结构，或者当第一限位结构为多个时，一部分第一限位结构可以为凸出结构，另一部分第一限位结构可以为凹槽结构。需要说明的是，轴500也可以为不规则结构，比如轴500的一部分表面为弧形结构，一部分表面为方形结构。
软胶连接带221设置有第二限位结构，第二限位结构设置在软胶连接带221远离扩展部分212的一面，第二限位结构可以与第一限位结构相匹配。比如：当第一限位结构为凸出结构时，第二限位结构可以为凹槽结构，此时第一限位结构可以容置在第二限位结构内，并与第二限位结构过盈配合连接，使得软胶连接带221在第一限位结构和第二限位结构的限位作用下按照预设运动轨迹运动(比如沿平行于壳体组件100的方向做直线运动)，进而使得扩展部分212按照预设运动轨迹运动至壳体组件100外部或壳体组件100内部。再比如：当第一限位结构为凹槽结构时，第二限位结构可以为凸出结构，此时第二限位结构可以容置在第一限位结构内，并与第一限位结构的槽壁过盈配合连接。还比如：当第一限位结构的数量为多个、一部分第一限位结构为凸出结构，一部分第一限位结构为凹槽结构时，相应地可以在软胶连接带221外表表面设置多个第二限位结构，其中一部分第二限位结构与凸出结构相匹配，一部分第二限位结构与凹槽结构相匹配。可以理解的是，第一限位结构和第二限位结构的形状大小相互匹配并相互抵接，限制软胶连接带221的运动路径。
例如，结合图7和图18所示，图18为图9所示柔性屏组件和轴沿P4-P4方向的剖面结构示意图。第一限位结构包括限位凹槽510，限位凹槽510围绕轴500的外表面设置，且限位凹槽510的槽宽从轴500的外表面朝轴500的内表面方向逐渐变窄。第二限位结构可以包括限位凸起2211，限位凸起2211设置在软胶连接带221的外表面，并凸出于软胶连接带221的表面，软胶连接带221的外表面指的是远离柔性屏组件200的一面，软胶连接带221的内表面指的是与柔性屏组件200的非显示面连接的一面。其中，限位凸起2211的材质与软胶连接带221的材质相同，比如均为橡胶，而且限位凸起2211的宽度从软胶连接带221的内表面朝软胶连接带221的外表面方向逐渐变宽，使得限位凸起2211的形状可以与限位凹槽510的形状相匹配，限位凸起2211可以嵌入到限位凹槽510内，且限位凸起2211可以通过限位凹槽510限制柔性屏组件200的运动轨迹，使得扩展部分212按照预设轨迹运动至壳体组件100内或壳体组件100外。限位凸起2211与限位凹槽510过盈配合连接，比如限位凸起2211的尺寸略大于限位凹槽510的尺寸，使得限位凸起2211安装至限位凹槽510内时，限位凸起2211的外表面与限位凹槽 510的槽壁相互挤压，以增加限位凹槽510和限位凸起2211的抵接牢固性，还可以增加轴500和软胶连接带221之间的摩擦系数，在轴500和软胶连接带221之间形成有效摩擦区。
可以理解的是，如果轴500和软胶连接带221之间的摩擦系数太小的话，可能会使得软胶连接带221绕轴500运动的过程中出现打滑的现象，进而使得扩展部分212的展开与收纳不顺畅。本申请实施例通过限位凹槽510和限位凸起2211可以使得软胶连接带221不易滑动，进而保证柔性屏组件200的显示可靠性。需要说明的是，限位凹槽510的形状并不限于此，比如限位凹槽510也可以为燕尾槽、方形槽等。
本申请实施例通过第一限位结构和第二限位结构的相互配合，使得柔性屏组件200可以按照预设运动轨迹展开在壳体组件100外或收纳在壳体组件100内，相比于相关技术，本申请实施例可以使得柔性屏组件200的扩展过程中不发生偏移，进而使得柔性屏组件200在电子设备20的长度方向不发生拉扯，进一步地保护柔性屏组件200不受损坏。
结合图7和图19所示，图19为本申请实施例提供的第一滑动件和第二滑动件的结构示意图。电子设备20还可以包括第一滑动件710和第二滑动件720，比如第一滑动件710可以设置在软胶连接带221上且位于主体部分310，第二滑动件720可以设置在软胶连接带221上且位于扩展部分212。其中，第一滑动件710和第二滑动件720均与软胶连接带221可滑动连接，且第一滑动件710和第二滑动件720均与轴500间隔设置，第一滑动件710和第二滑动件720均可沿着软胶连接带221的表面相对于软胶连接带221滑动，以使得扩展部分212按照所述预设运动轨迹展开于壳体组件100外部或收纳于壳体组件100内部。
初始状态下，第一滑动件710位于第一位置(如图7所示的)，第二滑动件720位于软胶连接带221的第二位置(如图7所示的)。当扩展部分212朝壳体组件100外的方向运动时，第一滑动件710和第二滑动件720均朝靠近轴500的方向运动，使得第一滑动件710位于第三位置(如图19所示)，第二滑动件720位于第四位置(如图19所示)，使得位于壳体组件100外的扩展部分212可以沿着第一滑动件710的表面滑动展开，位于壳体组件100内的扩展部分212可以沿着第二滑动件720的表面滑动至轴500的表面。当扩展部分212朝壳体组件100内的方向运动时，第一滑动件710和第二滑动件720均朝远离轴500的方向运动，使得位于壳体组件100外的扩展部分212可以沿着第一滑动件710的表面滑动至轴500的表面，位于壳体组件100内的扩展部分212可以沿着第二滑动件720滑动至壳体组件100内。
可以理解的是，第一滑动件710可以对逐渐绕出轴500外表面(或者是绕进轴500外表面)的扩展部分212进行运动限制，第二滑动件720可以对逐渐绕进轴500外表面(或者是绕出轴500外表面)的扩展部分212进行运动限制，进而限制整个扩展部分212的运动轨迹，使得扩展部分212按照第一预设运动轨迹逐渐展开于壳体组件100外(或者按照第二预设运动轨迹逐渐回收于壳体组件100内)。
如图20所示，图20为图9所示柔性屏组件和轴沿P5-P5方向的剖面结构示意图，第一滑动件710和第二滑动件720均设置有滑动部诸如滑动部730，滑动部730的大小形状于软胶连接带221上的第二限位结构的大小形状相适配。比如当第二限位结构为凹槽结构时，滑动部730可以为凸起结构；当第二限位结构为凸起结构时，滑动部730可以为凹槽结构。
软胶连接带221设置有限位部，用于限位第一滑动件710和第二滑动件720的滑动距离。比如软胶连接带221设置有第一限位部和第二限位部，第一限位部位于第一滑动件710和轴500之间，第一限位部用于限制第一滑动件710的滑动距离，以防止第一滑动件710滑动过度而抵到轴500；第二限位部位于第二滑动件720和轴500之间，第二限位部用于限制第二滑动件720的滑动距离，以防止第二滑动件720滑动过度而抵到轴500。其中，限位部可以为挡块、或者限位螺丝等可作为限位障碍的部件。
在一些实施例中，软胶连接带221可以设置有多个伸缩挡块，多个伸缩挡块间隔设置在软胶连接带221的不同位置，电子设备20可以控制伸缩挡块伸出于软胶连接带221表面或是缩回至软胶连接带221内部。用户可以对扩展部分212的展开尺寸进行选择，比如选择展开20％、展开50％或展开100％等，电子设备20根据用户所选择的展开尺寸，控制对应的伸缩挡块伸出软胶连接带221的表面，以阻挡软胶连接带221继续运动，进而控制扩展部分212的展开尺寸。相对于相关技术中的卷筒式柔性屏，本申 请实施例可以由用户根据自身的需求自由选择显示屏的扩展尺寸，更加智能和人性化。
需要说明的是，第一滑动件710的结构并不限于此，比如当软胶连接带221的尺寸等于扩展部分212的尺寸时，此时主体部分310并没有设置软胶连接带。第一滑动件710可以包括滑轨结构和可沿滑轨结构滑动的滑动结构，第一滑动件710可以采用刚性的材料制成，比如耐磨且刚性较大的赛钢或者金属材质等。滑轨结构的外表面与软胶连接带221的外表面齐平，且滑轨结构上设置有与第二限位结构的结构相同的凸起或凹槽，使得滑动结构可从滑轨结构滑动至软胶连接带221上。
需要说明的是，当设置的第一支撑片222是具有网孔2224结构的刚性片时，第二保护层2242的摩擦系数比较小，使得第一滑动件710和第二滑动件720可以直接沿着第二保护层2242的表面滑动，也可以减小第一滑动件710和第二滑动件720滑动过程中对第二保护层2242的摩擦力，进而减少第二保护层2242的磨损。
如图21和图22所示，图21为图2所示电子设备中轴的结构示意图，图22为图2所示电子设备中轴和驱动电机的结构示意图。电子设备20还可以包括驱动电机600，驱动电机600与轴500连接，驱动电机600可以驱动轴500转动，进而带动软胶连接带221朝壳体组件100外或壳体组件100内的方向运动。比如，轴500设置有通孔520，且通孔520的孔壁上设置有多个卡槽521，驱动电机600的输出轴610设置有多个卡齿611，卡齿611可以与卡槽521相互啮合以使得驱动电机600和轴500连接，驱动轴在驱动电机600的驱动下转动，进而带动轴500围绕驱动电机600转动。可以理解的是，驱动电机600和轴500可以共同组成带轮式马达装置，轴500以驱动电机600为中心转动，相比于将驱动电机600设置在轴500的外部，本申请实施例可以节省驱动电机600对电子设备20的占用空间。当然，将驱动电机600设置在轴500外，并在轴500的内部设置固定件，驱动电机600驱动轴500围绕固定件转动也是可以的。
当驱动电机600驱动轴500顺时针转动时，软胶连接带221在轴500的带动下，绕轴500的外表面朝壳体组件100外部的方向运动，使得扩展部分212逐渐展开在壳体组件100外；当驱动电机600驱动轴500逆时针转动时，软胶连接带221在轴500的带动下，绕轴500的外表面朝壳体组件100内部的方向运动，使得扩展部分212逐渐回收到壳体组件100内部。电子设备20还可以通过控制驱动电机600的工作时间以控制轴500的转动时间，进而控制扩展部分212的运动距离，使得扩展部分212的展开于壳体组件100外的尺寸可调节，可玩趣味性更高，提升用户体验。
