请参阅图1，图1为本申请实施例提供的电子设备的第一种结构示意图。电子设备诸如图1的电子设备20可为计算设备诸如膝上型计算机、包含嵌入式计算机的计算机监视器、平板电脑、蜂窝电话、媒体播放器、或其他手持式或便携式电子设备、较小的设备(诸如腕表设备、挂式设备、耳机或听筒设备、被嵌入在眼镜中的设备或者佩戴在用户的头部上的其他设备，或其他可佩戴式或微型设备)、电视机、不包含嵌入式计算机的计算机显示器、游戏设备、导航设备、嵌入式系统(诸如其中具有显示器的电子设备被安装在信息亭或汽车中的系统)、实现这些设备中的两个或更多个设备的功能的设备、或其他电子设备。在图1的示例性配置中，电子设备20是便携式设备，诸如蜂窝电话、媒体播放器、平板电脑、或者其他便携式计算设备。如果需要，其他配置可用于电子设备20。图1的示例仅是示例性的。
结合图1和图2所示，图2为本申请实施例提供的轴、驱动电机、连接带和柔性屏的组合结构示意图。电子设备20可包括壳体诸如壳体100，壳体100可由塑料、玻璃、陶瓷、纤维复合材料、金属(例如，不锈钢、铝等)、其他合适的材料、或这些材料的任意两种或更多种的组合形成。壳体100可使用一体式配置形成，在该一体式配置中，一些或全部壳体100被加工或模制成单一结构，或者可使用多个结构(例如，内框架结构、形成外部外壳表面的一种或多种结构等)形成。
其中，壳体100可以为规则形状，诸如长方体结构、圆角矩形结构。壳体100可以具有多个侧边，相邻两个侧边相互连接形成一个边角。侧边的数量可以为三个，比如壳体100可以包括第一侧边、第二侧边和第三侧边，第一侧边与第三侧边相对设置，第二侧边的一端与第一侧边的一端连接，第二侧边的另一端与第三侧边的一端连接。需要说明的是，壳体100也可以为不规则形状，侧边的数量也可以为四个、五个、或六个。
电子设备20可以包括限位件，限位件与壳体100可活动连接，使得限位件可相对于壳体100运动，比如限位件可以设置在第一侧边和第三侧边之间，限位件的一端与第一侧边的另一端可活动连接，限位 件的另一端与第三侧边的另一端可活动连接，使得限位件可以沿平行于壳体100的方向往返运动。其中，限位件可以为规则形状，比如圆柱体结构，或者半圆柱体结构，限位件也可以为不规则形状，比如限位件的其中一个面可以为圆弧面，其余面可以为平直结构的表面或者波浪形结构的表面等。限位件可以为独立于壳体100的额外设置的部件，限位件也可以为壳体100的其中一部分。
例如，限位件可以为轴诸如轴200，轴200与壳体100可拆卸连接，使得轴200可相对于壳体100运动，比如轴200可以设置在第一侧边和第三侧边之间，轴200的一端与第一侧边的另一端可拆卸连接，轴200的另一端与第三侧边的另一端可拆卸连接，使得轴200可以沿平行于壳体100的方向往返运动。
轴200可以为圆柱体结构，轴200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200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200的外表面并凸出于轴200的外表面的凸出结构，第一限位结构也可以为设置在轴200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200也可以为不规则结构，比如轴200的一部分表面为弧形结构，一部分表面为方形结构。
结合图3所示，图3为本申请实施例提供的电子设备的第二种结构示意图。电子设备20还可以包括柔性屏组件诸如柔性屏组件300，柔性屏组件300可以包括如图1所示的窄屏模式和如图3所示的宽屏模式，窄屏模式下，柔性屏组件300的显示面积固定；宽屏模式下，柔性屏组件300的显示面积可扩展。比如，柔性屏组件300可以包括柔性显示模组310和可形变的支撑件，支撑件位于柔性显示模组310的非显示面一侧，用于支撑柔性显示模组310。可以理解的是，支撑件的结构强度较高，一方面可以支撑柔性显示模组310，提高柔性显示模组的平整性，使得柔性显示模组310在显示过程不易塌陷或者说褶皱，另一方面支撑件还可以提高柔性屏组件300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310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310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。
柔性显示模组310可以包括主体部分311和扩展部分312，主体部分311设置在壳体100上，扩展部分312可相对于壳体100运动，使得扩展部分312可展开于壳体100外或回收于壳体100内。扩展部分312在运动过程中，可发生形变以在弯折状态和平直状态转换，限位件位于扩展部分312的弯折位置且抵持支撑件，使得限位件与支撑件可以一起支撑扩展部分312的弯折位置。
请继续参阅图2，支撑件还可以包括软胶连接带诸如软胶连接带320320，软胶连接带320软胶连接带320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320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320设置在扩展部分312的非显示面，软胶连接带320可以为扩展部分312提供一个平整的承载面，使得扩展部分312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320为的硬度在60度至75度之间，可以降低软胶连接带320运动过程中对扩展部分312的损坏，进而保护扩展部分312与软胶连接带320的接触面不易磨损。此外，由于扩展部分312在运动过程中，会经常与轴200产生摩擦进而使得扩展部分312容易破损。而本申请实施例通过在需要运动的扩展部分312增设软胶连接带320，可以将原本作用于扩展部分312的摩擦力转移到软胶连接带320上，可以进一步地保护扩展部分312。
软胶连接带320设置有第二限位结构诸如第二限位结构，第二限位结构设置在软胶连接带320远离扩展部分312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320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100的方向做直线运动)，进而使得扩展部分312按照预设运动轨迹运动至壳体100外部或壳体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320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320的运动路径。
当柔性屏组件300处于窄屏模式或宽屏模式时，主体部分311始终固定在壳体100的外表面，以裸露在电子设备20的外部，此时扩展部分312处于收纳状态，此时扩展部分312隐藏在壳体100的内部，无法用于显示信息，仅通过柔性屏组件300的主体部分311进行显示；当柔性屏从窄屏模式切换到宽屏模式时，用户可以拉动轴200朝远离壳体100的方向运动(或者可以设置驱动机构驱动轴200运动)，轴200在运动过程中会带动扩展部分312的至少一部分沿着轴200的外表面逐渐转动出壳体100外部，此时扩展部分312的至少一部分裸露在壳体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312可以与主体部分311一起显示信息，相对于仅使用主体部分311信息显示，可以增加显示面积。当柔性屏从宽屏模式切换到窄屏模式时，可以使扩展部分312朝靠近壳体100的方向沿轴200的外表面逐渐转动进壳体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300的展开或收纳)，使得扩展部分312的至少一部分收纳仅壳体100内，扩展部分312运动过程中会带动轴200朝壳体100的方向运动，进而缩短轴200与壳体100之间的距离(或者也可以通过机械驱动的方式驱动轴200的往复运动)。
本申请实施例通过在扩展部分设置软胶连接带，可以减少柔性屏组件300在运动过程的损坏程度，延长柔性屏组件300的使用寿命。此外，本申请实施例还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300按照预设运动轨迹展开在壳体100外或收纳在壳体100内，相比于相关技术，本申请实施例可以使得柔性屏组件300的扩展过程中不发生偏移，进而使得柔性屏组件300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300不受损坏。
如图4所示，图4为图2所示轴和柔性屏组件的第一种侧面结构示意图。软胶连接带320的尺寸等于扩展部分312的尺寸，软胶连接带320在柔性屏组件300上的投影位于扩展部分312，使得软胶连接带320可以覆盖整个扩展部分312的非显示面，进而保护整个扩展部分312。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312设置软胶连接带320，可以间隔扩展部分312与轴200直接接触，进而避免扩展部分312的非显示面直接与轴200的外表面相互摩擦过程中对扩展部分312造成的磨损。
如图5所示，图5为图2所示轴和柔性屏组件的第二种侧面结构示意图。软胶连接带320的尺寸也可以大于扩展部分312的尺寸。当软胶连接带320的尺寸大于扩展部分312的尺寸时，软胶连接带320在柔性屏组件300上的投影，一部分位于扩展部分312，一部分位于扩展部分312外，比如可以位于主体部分311上，也可以位于壳体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320中位于壳体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312展开或者回收。
当软胶连接带320的一部分位于主体部分311时，软胶连接带320的侧部外表面与主体部分311的侧部外表面齐平。比如，软胶连接带320和主体部分311均为长方体结构，软胶连接带320可以具有四个相互连接的侧部，且软胶连接带320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311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320设置在主体部分311的非显示面，软胶连接带320的四个侧部外表面与主体部分311的四个侧部外表面齐平，软胶连接带320可以对主体部分311起到支撑作用，使得主体部分311的显示面更平整，而且从外界也观察不到软胶连接带320，保持柔性屏组件300的外观简洁性。
如图6所示，图6为图2所示轴和柔性屏组件沿P1-P1方向的剖面结构示意图。第一限位结构包括第一限位槽210，第一限位槽210围绕轴200的外表面设置，且第一限位槽210的槽宽从轴200的外表面朝轴200的内表面方向逐渐变窄。第二限位结构包括第一限位凸起321，第一限位凸起321设置在软 胶连接带320的外表面，并凸出于软胶连接带320的表面，软胶连接带320的外表面指的是远离柔性屏组件300的一面，软胶连接带320的内表面指的是与柔性屏组件300的非显示面连接的一面。其中，第一限位凸起321的材质与软胶连接带320的材质相同，比如均为橡胶，而且第一限位凸起321的宽度从软胶连接带320的内表面朝软胶连接带320的外表面方向逐渐变宽，使得第一限位凸起321的形状可以与第一限位槽210的形状相匹配，第一限位凸起321可以嵌入到第一限位槽210内，且第一限位凸起321可以通过第一限位槽210限制柔性屏组件300的运动轨迹，使得扩展部分312按照预设轨迹运动至壳体100内或壳体100外。第一限位凸起321与第一限位槽210过盈配合连接，比如第一限位凸起321的尺寸略大于第一限位槽210的尺寸，使得第一限位凸起321安装至第一限位槽210内时，第一限位凸起321的外表面与第一限位槽210的槽壁相互挤压，以增加第一限位槽210和第一限位凸起321的抵接牢固性，还可以增加轴200和软胶连接带320之间的摩擦系数，在轴200和软胶连接带320之间形成有效摩擦区。可以理解的是，如果轴200和软胶连接带320之间的摩擦系数太小的话，可能会使得软胶连接带320绕轴200运动的过程中出现打滑的现象，进而使得扩展部分312的展开与收纳不顺畅。本申请实施例通过第一限位槽210和第一限位凸起321可以使得软胶连接带320不易滑动，进而保证柔性屏组件300的显示可靠性。需要说明的是，第一限位槽210的形状并不限于此，比如第一限位槽210也可以为燕尾槽、方形槽等。
如图7至图10所示，图7为本申请实施例提供的柔性屏组件的第一种结构示意图，图8为图7所示柔性屏组件中第一支撑片的第一种结构示意图，图9为图8所示第一支撑片的局部结构示意图，图10为图8所示第一支撑片沿P3-P3的剖面结构示意图，图11为图8所示第一支撑片沿P4-P4的剖面结构示意图。
支撑件还可以包括第一支撑片330，第一支撑片330为刚性结构，比如第一支撑片330可以采用金属材料制成，诸如第一支撑片330可以为钢片、铝片、铜片等。第一支撑片330也可以采用橡胶材质、硅胶材质制成。第一支撑片330嵌入设置在软胶连接带320的内部，比如可以采用在第一支撑片330注塑成型出软胶连接带320的方式，使得第一支撑片330包裹在软胶连接带320的内部，进而使得第一支撑片330不直接与柔性屏组件300接触，达到保护柔性屏组件300的目的。
第一支撑片330可以产生形变以使第一支撑片330在第一状态和第二状态转换，在第一状态下，第一支撑片330为直形，以支撑所述平直状态的扩展部分312；在第二状态下，第一支撑片330为弯形，以支撑处于弯折状态的扩展部分312。可以理解的是，第一支撑片330为可发生形变的结构，其可以根据扩展部分312所处的状态而进行第一状态和第二状态的切换，使得第一支撑片330既可以对弯折状态下的扩展部分312进行支撑，又可以对平直状态下的扩展部分312进行支撑。
例如，第一支撑片330可以包括第一侧部331、第二侧部332和凹陷部333，凹陷部333位于第一侧部331和第二侧部332之间，第一侧部331位于轴200的一端端部，第二侧部332位于轴200的另一端端部，凹陷部333位于轴200的中间位置。其中凹陷部333朝背离柔性显示模组310的方向弯曲形成。可以理解的是，第一支撑片330的结构类似于卷尺的结构，第一支撑片330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330的弯曲方向背向轴200。当软胶连接带320沿轴200的外表面运动的过程中，第一支撑片330可发生形变以使凹陷部333在第一弯曲状态和第二弯曲状态之间切换。
例如，第一支撑片330处于第一状态时，凹陷部333处于第一弯曲状态，第一弯曲状态指的是朝背离柔性显示模组310的方向弯曲的状态。当软胶连接带320沿轴200运动的过程中，运动至轴200位置的软胶连接带320会与轴200抵接，在这个过程中，位于软胶连接带320内部的第一支撑片330可以通过软胶连接带320接收到沿轴200的径向的作用力并产生形变，使得凹陷部333从第一弯曲状态切换为第二弯曲状态，其余未与轴200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333朝靠近柔性显示模组310的方向弯曲的状态，使得第一支撑片330的弯曲方向与轴200的弧度相同，进而提高软胶连接带320与轴200的贴合程度，使得软胶连接带320的运动更平稳。当软胶连接带320沿着轴200的外表面方向逐渐运动到壳体100外或壳体100内时，原先与轴200抵接的软胶连接带逐渐远离轴200，此时轴200对第一支撑片330的挤压作用力也会逐渐撤销，进而使得凹陷部333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330在第一状态下，第一支撑片330的截面形状如图10所示，第一支撑片330在第一状态下是呈凹陷状，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330的形状与扩展部分312的形状相同，进而使得扩展部分312可沿着轴200的表面运动。基于该第一支撑片330的结构，使得第一支撑片330在接收到沿轴200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11所示；并在未接收到沿轴200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330的结构并不局限于此，比如第一支撑片330可以具有多个凹陷部333，多个凹陷部333间隔排布，一个凹陷部333朝背离柔性显示模组310的方向弯曲形成，当扩展部分运动至轴200上时，全部或部分凹陷部333接收到沿轴200的径向的作用力时产生形变，以使凹陷部333从固定部分的非显示面朝固定部分的显示面方向弯曲，此时多个凹陷部333从第一弯曲状态切换至第二弯曲状态。当扩展部分312远离轴200时，凹陷部333恢复至朝背离柔性显示模组310的方向弯曲的状态。
可以理解的是，如果第一支撑片330为普通的平直状的刚性结构时，当第一支撑片330运动到轴200的位置时，由于轴200与第一支撑片330之间的相互作用力，会使得第一支撑片330变形为弯折状态进而使得第一支撑片330贴合轴200的外表面，当第一支撑片330离开轴200的位置时，此时轴200与第一支撑片330之间的相互作用力消失，但由于第一支撑片330为平直状的刚性结构，其变型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312呈现不平整的情况，影响电子设备20的显示效果。而本申请的凹陷部333可以在第一弯曲状态和第二弯曲状态之间切换，使得在轴200的位置时(或者说弯折位置时)从第一弯曲状态切换至第二弯曲状态，运动到其他位置时又从第二弯曲状态切换回第一弯曲状态，即可以实现扩展部分312在展开状态和回收状态的自由切换，又可以使得扩展部分312在展开状态和回收状态均保持平整，减少扩展部分312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，也可以不设置软胶连接带320，替代性地，直接将第一支撑片330设置在扩展部分312的非显示面。第一支撑片330可以采用双面胶或胶水等粘接剂直接粘接到扩展部分312的非显示面上。
例如，第一支撑片330可以直接设置在柔性显示模组310的非显示面一侧，第一支撑片330可以产生形变以使第一支撑片330在第一状态和第二状态转换，在第一状态下，第一支撑片330为直形，以支撑所述平直状态的扩展部分312；在第二状态下，第一支撑片330为弯形，以支撑处于弯折状态的扩展部分312。可以理解的是，第一支撑片330为可发生形变的弹性结构，其可以根据扩展部分312所处的状态而进行第一状态和第二状态的切换，使得第一支撑片330既可以对弯折状态下的扩展部分312进行支撑，又可以对平直状态下的扩展部分312进行支撑。
当第一支撑片330处于第一状态时，第一支撑片330的一部分未与扩展部分312接触，比如可以是第一支撑片330的中间具有凹陷结构，第一支撑片330的两侧与扩展部分312接触，第一支撑片330的中间与扩展部分312具有间隙；还可以是第一支撑片330具有多个凹陷结构，第一支撑片330在具有凹陷结构的部分与扩展部分312具有间隙，第一支撑片330的其他部分与扩展部分312接触或者说贴合扩展部分312的非显示面接触。当第一支撑片330处于第二状态时，由于第一支撑片330接收到沿轴200的径向的作用力，使得第一支撑片330产生形变，进而使得原先第一支撑片330未与扩展部分312接触的一部分贴合到扩展部分312的显示面上，进而使得第一支撑片330的外形与扩展部分312的外形一致，从而保证柔性屏组件300可以按照预设运动轨迹反复展开和回收。
当扩展部分312位于壳体100内时，第一支撑片330的一部分与轴200抵接。比如第一支撑片330的一部分与轴200的表面抵接，第一支撑片330的一部分与轴200不接触(可以理解成第一支撑片330的一部分不挨着轴200)。
当扩展部分312位于壳体100外时，第一支撑片330的一部分与轴200抵接。比如第一支撑片330的一部分与轴200的表面抵接，第一支撑片330的一部分与轴200不接触(可以理解成第一支撑片330的一部分不挨着轴200)。可以理解的是，此时扩展部分312的一部分平铺在壳体100外，扩展部分312的一部分套在轴200的表面。
第一支撑片330在扩展部分312的运动方向上的尺寸可以大于或等于扩展部分312的尺寸，当第一 支撑片330在扩展部分312的运动方向上的尺寸等于扩展部分312的尺寸时，第一支撑片330在柔性屏组件300上的投影位于扩展部分312，使得第一支撑片330可以覆盖整个扩展部分312的非显示面，进而支撑整个扩展部分312。相对于相关技术中，直接将柔性显示模组作为拉伸主体，本申请在扩展部分312设置第一支撑片330，可以间隔扩展部分312与轴200直接接触，进而避免扩展部分312的非显示面直接与轴200的外表面相互摩擦过程中对扩展部分312造成的磨损。当第一支撑片330的尺寸大于扩展部分312的尺寸时，第一支撑片330在柔性屏组件300上的投影，一部分位于扩展部分312，一部分位于扩展部分312外，比如可以位于主体部分311上，也可以位于壳体100的容置空间内。
当第一支撑片330的一部分位于固定部分时，第一支撑片330的侧部外表面与主体部分311的侧部外表面齐平。比如，第一支撑片330和主体部分311均为长方体结构，第一支撑片330可以具有四个相互连接的侧部，且第一支撑片330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311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330设置在主体部分311的非显示面，第一支撑片330的四个侧部外表面与主体部分311的四个侧部外表面齐平，第一支撑片330可以对主体部分311起到支撑作用，使得主体部分311的显示面更平整，而且从外界也观察不到第一支撑片330，保持柔性屏组件300的外观简洁性。
需要说明的是，第一支撑片330也可以不位于主体部分311上，比如图12所示，图12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，支撑件还可以包括第二支撑片340，第二支撑片340位于主体部分311的非显示面。第二支撑片340的结构与第一支撑片330的结构不同，比如第二支撑片340为平直结构，其并不具有弧形结构，第二支撑片340可以为主体部分311提供平整的承载面。需要说明的是，第二支撑片340的结构可以与第一支撑片330相同，可便于加工。
可以理解的是，为实现显示屏模组在拉伸弯折区，其显示屏模组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，如显示屏模组中的各层薄膜材料，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。并且显示屏模组在拉伸状态下是不能直接受力的，因为这样很容易导致显示屏模组损坏。显然，要实现显示屏模组在折弯位置按既定轨迹实现伸缩，并且保证显示屏本体不单独受力，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330的结构进行改进，使得第一支撑片330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330的结构并不局限于此，比如第一支撑片330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330在轴200的外表面运动的过程中可以被拉伸，从而保证第一支撑片330在伸缩折弯区能够轻松实现对扩展部分312的支撑且在沿轴200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312的非显示面设置刚性片，刚性片运动到轴200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312的支撑力度不足，进而导致柔性屏组件300出现褶皱或凹陷的不良现象产生。
例如，如图13所示，图13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330的全部或一部分设置有多个网孔诸如网孔334以提高第一支撑片330的可形变能力，比如可以采用酸性蚀刻液对第一支撑片330进行蚀刻，以在第一支撑片330上蚀刻出多个菱形的网孔334，使得第一支撑片330呈菱形丝网结构，菱形丝网结构可以使得第一支撑片330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330在电子设备20的宽度方向上运动时，第一支撑片330会接收到轴200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330可以保证在运动过程中不会因为张力过大而断裂。
网孔334可以为规则形状，比如为菱形结构，矩形结构等，网孔334也可以为不规则形状。比如，本申请实施例的网孔334为菱形结构，第一支撑片使得第一支撑片330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330的优势在于柔韧度非常好，并且在保证柔性屏组件300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330的尺寸等于扩展部分312的尺寸时，可以将第一支撑片330均加工成菱形丝网结构；当第一支撑片330的尺寸大于扩展部分312的时候，可以将第一支撑片330位于扩展部分312的非显示面的部分加工成菱形丝网结构，第一支撑片330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330位于主体部分311的非显示面的部分。可以理解的是，第一支撑片330可以包括第一段和第二段，其中第一段设置在主体部分311的非显示面，第一段为完成的刚性片结构，表面无网孔设计，第二段设置在扩展部分312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330的运动过程中，主要是位于扩展部分312的非显示面的第一支撑片330部分受力，只将第一支撑片330的一部分加工成菱形丝网结构，一方面保证第一支撑片330的可形变能力，另一方面又可以保证整个第一支撑片330的支撑力度，而且还可以降低制造的难度和成本。
结合图8和图14所示，图14为本申请实施例提供的柔性屏组件的第二种结构示意图。电子设备20还包括保护层400，保护层400可以为PI(PolyimideFilm，聚酰亚胺薄膜)膜。当然保护层400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330夹设在两个保护层400之间，且保护层400覆盖在网孔334上以封堵网孔334，使得设置在第一支撑片330上的物体(比如双面胶、胶水等粘接剂)不会通过网孔334渗透入其他部件上。比如第一支撑片330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300的非显示面的一面，第二侧面为远离柔性屏组件300的一面。其中第一侧面设置有第一保护层410，第一保护层410盖设在网孔334上以从第一侧面朝第二侧面的方向封堵网孔334；第二侧面设置有第二保护层420，第二保护层420盖设在网孔334上以从第二侧面朝第一侧面的方向封堵网孔334，进而使得设置在第一支撑片330(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334渗透到柔性屏组件300、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330，不但可以增加拉伸强度，而且还可以减小了柔性屏组件300的破坏风险，延长柔性屏组件300的使用寿命。
结合图4和图15所示，图15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510和第二滑动件520，比如第一滑动件510可以设置在软胶连接带320上且位于主体部分311，第二滑动件520可以设置在软胶连接带320上且位于扩展部分312。其中，第一滑动件510和第二滑动件520均与软胶连接带320可滑动连接，且第一滑动件510和第二滑动件520均与轴200间隔设置，第一滑动件510和第二滑动件520均可沿着软胶连接带320的表面相对于软胶连接带320滑动，以使得扩展部分312按照所述预设运动轨迹展开于壳体100外部或收纳于壳体100内部。
初始状态下，第一滑动件510位于第一位置(如图4所示的)，第二滑动件520位于软胶连接带320的第二位置(如图4所示的)。当扩展部分312朝壳体100外的方向运动时，第一滑动件510和第二滑动件520均朝靠近轴200的方向运动，使得第一滑动件510位于第三位置(如图13所示)，第二滑动件520位于第四位置(如图13所示)，使得位于壳体100外的扩展部分312可以沿着第一滑动件510的表面滑动展开，位于壳体100内的扩展部分312可以沿着第二滑动件520的表面滑动至轴200的表面。当扩展部分312朝壳体100内的方向运动时，第一滑动件510和第二滑动件520均朝远离轴200的方向运动，使得位于壳体100外的扩展部分312可以沿着第一滑动件510的表面滑动至轴200的表面，位于壳体100内的扩展部分312可以沿着第二滑动件520滑动至壳体100内。
可以理解的是，第一滑动件510可以对逐渐绕出轴200外表面(或者是绕进轴200外表面)的扩展部分312进行运动限制，第二滑动件520可以对逐渐绕进轴200外表面(或者是绕出轴200外表面)的扩展部分312进行运动限制，进而限制整个扩展部分312的运动轨迹，使得扩展部分312按照第一预设运动轨迹逐渐展开于壳体100外(或者按照第二预设运动轨迹逐渐回收于壳体100内)。
如图16所示，图16为图2所示轴和柔性屏组件沿P2-P2方向的剖面结构示意图，第一滑动件510和第二滑动件520均设置有滑动部诸如滑动部530，滑动部530的大小形状于软胶连接带320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530可以为凸起结构；当第二 限位结构为凸起结构时，滑动部530可以为凹槽结构。
软胶连接带320设置有限位部，用于限位第一滑动件510和第二滑动件520的滑动距离。比如软胶连接带320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510和轴200之间，第一限位部用于限制第一滑动件510的滑动距离，以防止第一滑动件510滑动过度而抵到轴200；第二限位部位于第二滑动件520和轴200之间，第二限位部用于限制第二滑动件520的滑动距离，以防止第二滑动件520滑动过度而抵到轴200。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320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320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320表面或是缩回至软胶连接带320内部。用户可以对扩展部分312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320的表面，以阻挡软胶连接带320继续运动，进而控制扩展部分312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510的结构并不限于此，比如当软胶连接带320的尺寸等于扩展部分312的尺寸时，此时主体部分311并没有设置软胶连接带。第一滑动件510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510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320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320上。
需要说明的是，当设置的第一支撑片330是具有网孔334结构的刚性片时，第二保护层420的摩擦系数比较小，使得第一滑动件510和第二滑动件520可以直接沿着第二保护层420的表面滑动，也可以减小第一滑动件510和第二滑动件520滑动过程中对第二保护层420的摩擦力，进而减少第二保护层420的磨损。
如图17和图18所示，图17为图2所示轴、驱动电机和柔性屏组件中轴的结构示意图，图18为图2所示轴、驱动电机和柔性屏组件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200连接，驱动电机600可以驱动轴200转动，进而带动软胶连接带320朝壳体100外或壳体100内的方向运动。比如，轴200设置有通孔220，且通孔220的孔壁上设置有多个卡槽221，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221相互啮合以使得驱动电机600和轴200连接，驱动轴在驱动电机600的驱动下转动，进而带动轴200围绕驱动电机600转动。可以理解的是，驱动电机600和轴200可以共同组成带轮式马达装置，轴200以驱动电机600为中心转动，相比于将驱动电机600设置在轴200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200外，并在轴200的内部设置固定件，驱动电机600驱动轴200围绕固定件转动也是可以的。
当驱动电机600驱动轴200顺时针转动时，软胶连接带320在轴200的带动下，绕轴200的外表面朝壳体100外部的方向运动，使得扩展部分312逐渐展开在壳体100外；当驱动电机600驱动轴200逆时针转动时，软胶连接带320在轴200的带动下，绕轴200的外表面朝壳体100内部的方向运动，使得扩展部分312逐渐回收到壳体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200的转动时间，进而控制扩展部分312的运动距离，使得扩展部分312的展开于壳体100外的尺寸可调节，可玩趣味性更高，提升用户体验。
如图19和20所示，图19为本申请实施例提供的电子设备的第三种结构示意图，图20为图19所示电子设备中驱动装置的结构示意图。电子设备20还可以包括驱动装置700，驱动装置700用于驱动轴200的沿壳体100的方向进行往复运动，实现轴200与壳体100之间的嵌合和分离。驱动装置700可以包括第一电机710和推动机构720，推动机构720与第一电机710连接，第一电机710用于驱动推动机构720推动轴200沿平行于壳体100的方向往复运动，使得轴200伸出或进入壳体100，实现轴200和壳体100之间的分离或嵌合。
其中，推动机构720可以包括传动组件诸如传动组件721和推动组件诸如推动组件722，传动组件721与第一电机710连接，推动组件722的一端与传动组件721连接，推动组件722的另一端与轴200 连接。第一电机710用于驱动传动组件721运动，使得与其连接的推动组件722跟随传动组件721运动，进而使得推动组件722沿平行于壳体100的方向运动。传动组件721可以为丝杆传动组件、齿轮组或伸缩组件中的一种或几种的组合，其中伸缩组件可以包括电动推杆、电液推杆、气动推杆或液压推杆等。
推动组件722可以包括第一基座诸如第一基座7221和推杆诸如推杆7222。其中，第一基座7221固定在壳体100的内表面，第一基座7221上设置有滑槽，推杆7222设置在滑槽内且与滑槽可滑动连接以使推杆7222可在滑槽内滑动。推杆7222的一端与传动组件721连接，推杆7222的另一端与轴200连接。
当电子设备20要控制壳体100和轴200进行相对运动时，可以控制第一电机710驱动传动组件721运动，传动组件721运动时带动推杆7222在推杆7222在滑槽内沿平行于壳体100的方向滑动，进而带动轴200沿平行于壳体100的方向运动，以实现壳体100和轴200的嵌合和分离。
例如，电子设备20可以控制第一电机710的输出轴正向(或反向)转动，使得与第一电机710的输出轴连接的传动组件721跟随第一电机710的输出轴运动，传动组件721运动过程中将会带动推杆7222朝背离壳体100的方向运动，与推杆7222相连接的轴200会跟随推杆7222的运动而运动，使得轴200也朝背离壳体100的方向运动，进而使得轴200从壳体100内伸出，实现轴200与壳体100分离。再例如：电子设备20可以控制第一电机710的输出轴反向(或正向)转动，使得与第一电机710的输出轴连接的传动组件721跟随第一电机710的输出轴运动，传动组件721运动过程中将会带动推杆7222朝靠近壳体100的方向运动，与推杆7222相连接的轴200会跟随推杆7222的运动而运动，使得轴200也朝靠近壳体100的方向运动，进而使得轴200从壳体100外部收缩至壳体100内，实现轴200与壳体100嵌合。
推杆7222的外表面还设置有弹性件诸如弹性件7223，弹性件7223可以为弹簧或其他具有弹性的部件。弹性件7223可以用于支撑和保护推杆7222，比如当电子设备20跌落时，弹性件7223可以起到缓冲作用，减少推杆7222所受到的瞬间冲击力，进而减少对与推杆7222连接的传动组件721的冲击力，保护传动组件721不受损坏。
请继续参阅图20，传动组件721可以包括第二基座7211、传动丝杆7212和连接件7213，其中第二基座7211固定在壳体100上。传动丝杆7212与第二基座7211可转动连接，比如传动丝杆7212可以通过与嵌入设置在第二基座7211上的轴承连接，进而实现传动丝杆7212可相对于第二基座7211转动。传动丝杆7212还与第一电机710连接，第一电机710用于驱动传动丝杆7212相对于第二基座7211转动。连接件7213套设于传动丝杆7212上且连接件7213与传动丝杆7212传动连接，连接件7213还与推杆7222连接，连接件7213在传动丝杆7212的带动下沿垂直于传动丝杆7212的轴向方向往复运动，进而带动推杆7222沿平行于壳体100进行往复运动，推杆7222进行往复运动时，轴200跟随推杆7222进行往复运动。
结合图21所示，图21为图20所示驱动装置中连接件的结构示意图。传动组件721还可以包括导杆诸如导杆7214，导杆7214设置在第二基座7211上，比如导杆7214的两端可以直接插设固定于第二基座7211的连接孔内。其中，导杆7214与传动丝杆7212并列且平行设置，连接件7213可以同时套设在传动丝杆7212和导杆7214上，导杆7214对连接件7213可以起到导向定位的作用。比如，连接件7213可以设置有第一通孔7213a，第二通孔7213b和第三通孔7213c，连接件7213通过第一通孔7213a套设在传动丝杆7212上，通过第二通孔7213b套设在推杆7222上，并通过第三通孔7213c套设在导杆7214上且与导杆滑动接触。第一通孔7213a的孔壁上设置有传动螺纹，该传动螺纹与传动丝杆7212的螺齿相啮合，使得传动丝杆7212转动时通过第一通孔7213a带动连接件7213沿平行于壳体100的方向做直线运动。可以理解的是，传动丝杆7212的转动可以转化为连接件7213的直线运动。
如图22和图23所示，图22为本申请实施例提供的电子设备的第四种结构示意图，图23为图22所示电子设备中驱动装置的结构示意图。传动组件721也可以为齿轮组传动，比如传动组件721包括齿轮诸如齿轮7215，齿轮7215设置在第一电机710的输出轴上，第一电机710可以驱动齿轮7215转动。推杆7222与齿轮7215传动连接，比如可以在推杆7222的外表面设置有多个啮齿，推杆7222通过啮齿与齿轮7215啮合，使得齿轮7215转动时可带动推杆7222沿平行于壳体100的方向进行往复运动。需 要说明的是，传动组件721也可以包括多个齿轮，通过多个齿轮的相互传动来带动推杆7222的往复运动。
结合图3、图22和图24所示，图24为本申请实施例提供的电子设备的第五种结构示意图。电子设备20还可以包括第二电机800，第二电机800与软胶连接带320连接，第二电机800可以用于驱动软胶连接带320跟随壳体100和轴200的相对运动而运动，将柔性屏组件300的一部分回收于壳体100内或者将柔性屏组件300的一部分展开于壳体100外，以增加电子设备20的显示面积。
当驱动装置700驱动轴200朝背离壳体100的方向运动时，第二电机800可以在预设间隔时间后驱动软胶连接带320跟随轴200运动，使得原先收纳在壳体100内部的扩展部分312沿轴200的外表面慢慢滑动并逐步展开在壳体100外部(或者说电子设备20的外部)诸如图3所示，进而使得扩展部分312展开在电子设备20的外部，主体部分311和扩展部分312可以共同显示一个画面，也可以分别显示两个画面，相比于只用初始状态下的只采用主体部分311进行显示，将扩展部分312展开在壳体100内的外部，可以增加电子设备20的显示面积。
本申请实施例通过设置两个驱动装置分别对壳体100与轴200以及软胶连接带320的运动状态进行控制，使得柔性屏组件300的显示面积可选择。相对于相关技术中安装空间固定的显示屏，本申请实施例可以在无需额外增加柔性屏组件300(或者说显示屏)安装空间的情况下增加电子设备20的显示面积。
请继续参阅图22和图24，第二电机800用于驱动软胶连接带320卷曲或者伸展，以使扩展部分312收纳在壳体100内或者是展开在壳体100外部。例如，软胶连接带320的一端饶设在第二电机800的输出轴上，软胶连接带320的另一端与壳体100连接，相对于将柔性屏组件300直接跟第二电机800和壳体100连接，本申请实施例可以将拉伸对象转嫁到软胶连接带320上，可以降低柔性屏组件300在拉伸过程中的损坏程度。
当电子设备20要控制柔性屏组件300展开于壳体100外时，电子设备20可以控制第二电机800驱动软胶连接带320从卷曲状态逐渐变为伸展状态，进而使得扩展部分312可以沿着轴200的外表面朝远离第二电机800的方向滑动，以将原本收纳在壳体100内部的扩展部分312逐渐展开在电子设备20(或者说壳体100)的外部，与原先裸露在电子设备20外部的主体部分311共同显示画面。
当电子设备20要控制柔性屏组件300收纳于壳体100内时，电子设备20可以控制第二电机800驱动软胶连接带320从伸展状态逐渐变为卷曲状态，进而使得柔性屏组件300可以沿着轴200的外表面朝靠近第二电机800的方向慢慢滑动，以将原本展开在电子设备20(或者说壳体100)的外部的扩展部分312逐渐回收至壳体100内。
其中，扩展部分312的尺寸小于或等于壳体100的尺寸，使得扩展部分312收纳在壳体100内时可完全展开，无需卷曲，相对于相关技术中需要卷曲的显示屏，本申请实施例可以避免由于柔性屏经常卷曲而容易受损，可以延长柔性屏的使用寿命。
在驱动装置700驱动壳体100和轴200相对运动时，如果第二电机800与驱动装置700同时运动，会使柔性屏组件300松弛，进而可能会导致柔性屏组件300出现褶皱或不平整的等不良现象，进而影响到电子设备20的画面显示效果。
如图25所示，图25为本申请实施例提供的电子设备的第六种结构示意图。为了使得柔性屏组件300始终处于绷紧状态，保证柔性屏组件300的张力，本申请实施例的电子设备20的处理器诸如处理器900，处理器900与驱动装置700和第二电机800电性连接，处理器900可以用于在不同时刻驱动驱动装置700驱动壳体100和轴200相对运动以及第二电机800驱动软胶连接带320跟随壳体100与轴200的相对运动而运动，使得驱动装置700和第二电机800分步异时驱动。可以理解的是，驱动装置700和第二电机800的驱动时间存在一个时间差，这个时间差很短暂，主要用于保证柔性屏组件300的两端始终处于受力绷紧状态，保证柔性屏组件300的张力，确保不出现褶皱和不平整等不良现象，进而使得电子设备20的画面显示效果不受柔性屏组件300移动的影响。
例如，当需要展开扩展部分312时，处理器900可以在第一时刻T1控制驱动装置700驱动轴200朝背离壳体100的方向运动，使得轴200慢慢伸出壳体100外，以实现壳体100和轴200的分离。在轴200运动到第二时刻T2时，处理器900控制第二电机800驱动软胶连接带320慢慢展开，使得柔性屏 组件300的扩展部分312可以沿轴200的外表面滑动至壳体100外。其中，第一时刻T1早于第二时刻T2，比如T2＝T1+t1，t1为第一预设间隔时间，第一预设间隔时间可以根据实际情况进行设置，本申请实施例对其并不予以限定。可以理解的是，在展开扩展部分312时，轴200比软胶连接带320先运动，使得软胶连接带320始终处于绷直状态，进而使得柔性屏组件300在扩展部分312逐渐展开在壳体100外的过程中始终处于绷直状态。
当需要将扩展部分312回收至壳体100内时，处理器900可以在第三时刻T3控制第二电机800驱动软胶连接带320的一部分慢慢卷曲，软胶连接带320在卷曲过程中带动扩展部分312朝靠近第二电机800的方向运动。在柔性屏组件300运动到第四时刻T4时，处理器900控制驱动装置700驱动轴200朝背离壳体100的方向运动，使得轴200慢慢缩回至壳体100内，以实现壳体100和轴200的嵌合。其中，第三时刻T3早于第四时刻T4，比如T4＝T3+t2，t2为第二预设间隔时间，第二预设间隔时间可以根据实际情况进行设置，本申请实施例对其并不予以限定。可以理解的是，在回收扩展部分312时，软胶连接带320比轴200先运动，使得软胶连接带320始终处于绷直状态，进而使得柔性屏组件300在扩展部分312逐渐回收到壳体100内的过程中始终处于绷直状态。
在其他一些实施例中，处理器900也可以根据软胶连接带320的张力值进行驱动装置700和第二电机800的控制。比如，可以在软胶连接带320上设置张力检测器，张力检测器用于检测软胶连接带320的张力值。当需要展开扩展部分312时，处理器900先控制驱动装置700启动，并获取张力检测器所检测到软胶连接带320的第一张力值，当软胶连接带320的第一张力值大于第一预设张力值时控制第二电机800启动。同样地，当需要回收扩展部分312时，处理器900先控制第二电机800启动，并获取张力检测器所检测到的软胶连接带320的第二张力值，当软胶连接带320的第二张力值大于第二预设张力值时控制驱动装置启动。本申请实施例根据软胶连接带320的张力值的大小确定驱动装置700和第二电机800的启动时间，可以避免由于两者的启动时间间隔过小而导致软胶连接带320的张力值过小而使柔性屏组件300褶皱的情况，也可以避免由于两者的启动时间间隔过大而导致软胶连接带320的张力值过大而损坏的情况。相比于根据固定时间间隔对两个驱动装置的启动控制，本申请实施例的控制更加准确和智能。
上述实施例中，替代性地，电子设备20可以只设置驱动装置700而不设置第二电机800，诸如图26所示，图26为本申请实施例提供的电子设备的第七种结构示意图。软胶连接带320的一端与壳体100连接，软胶连接带320的另一端与驱动装置700连接，驱动装置700驱动壳体100和轴200相对运动并带动软胶连接带320运动，使得扩展部分312伸出于壳体100外，以使扩展部分312可以与主体部分311共同显示画面。
如图27和图28所示，图27为图26所示电子设备中驱动装置的结构示意图，图28为图26所示驱动装置中推动组件的结构示意图。推杆7222包括支撑部7222a、转轴7222b和推动部7222c，推动部7222c的一端固定在支撑部7222a上，推动部7222c的另一端与轴200，转轴7222b设置在支撑部7222a中远离轴200的一端，转轴7222b与软胶连接带320传动连接。比如，软胶连接带320套在转轴7222b上且与软胶连接带320的两端与壳体100固定连接。
当需要展开扩展部分312时，处理器900可以控制第一电机710驱动传动组件721运动，传动组件721带动推动组件722朝背离壳体100的方向运动，推动组件722在运动过程中通过推动部7222c推动轴200也朝背离壳体100的方向运动，与此同时由于转轴7222b也朝背离壳体100的方向运动，使得软胶连接带320也跟随转轴7222b朝背离壳体100的方向运动且沿着转轴7222b的外表面滑动，进而增加软胶连接带320的伸展长度，扩展部分312在软胶连接带320的带动下滑动至壳体100外，以使得扩展部分312裸露在电子设备20外部。
当需要回收扩展部分312时，处理器900可以控制第一电机710驱动传动组件721运动，传动组件721带动推动组件722朝靠近壳体100的方向运动，推动组件722在运动过程中通过推动部7222c拉着轴200也朝靠近壳体100的方向运动，与此同时由于转轴7222b也朝靠近壳体100的方向运动，使得软胶连接带320也跟随转轴7222b朝靠近壳体100的方向沿着转轴7222b的外表面滑动，进而减少软胶连接带320的伸展长度，扩展部分312在软胶连接带320的带动下滑动至壳体100内，以使得扩展部分312 回收至壳体100内部。
需要说明的是，柔性屏组件300的扩展部分312在展开至壳体100外或回收至壳体100内的过程中，柔性屏组件300在轴200和软胶连接带320的共同作用下保持绷直状态，确保电子设备20的画面显示效果不受影响。
为了避免软胶连接带320与转轴7222b的摩擦力过大，导致软胶连接带320的张力过大损坏，本申请实施例中的转轴7222b可转动，比如转轴7222b套设在固定轴7222d的外部，且与固定轴7222d可转动连接以使得转轴7222b可围绕固定轴7222d转动，进而使得软胶连接带320运动时可以带动转轴7222b转动，进而可以减小软胶连接带320与转轴7222b之间的摩擦力，使得软胶连接带320运动起来更顺畅。而且转轴7222b还可以与轴200组成联合的滚动机构，进而保证柔性屏组件300的顺利回收和顺利展开。
可以理解的是，本申请实施例中的第一电机710提供主动驱动效果，轴200和转轴7222b为联动机构，在第一电机710的主动驱动下进行联动运动，使得推动部7222c的运动距离、扩展部分312的展开长度和软胶连接带320的运动距离相等，进而保证柔性屏组件300在展开过程和回收过程，都处于时刻绷紧状态(保证柔性屏组件300的张力处于一定范围内)，避免出现如展开不同步导致柔性屏组件300的张力过大受损或者柔性屏组件300的张力过小褶皱等异常情况。
本申请实施例通过驱动装置700即可实现壳体100与轴200的相对运动以及柔性屏组件300的展开与回收，相对于上述申请实施例可以减少一个驱动装置，可以在上述申请实施例的基础上简化电子设备20的结构。
以上对本申请实施例提供的柔性屏组件以及电子设备进行了详细介绍。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。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。
