下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有付出创造性劳动前提下所获得的所有其他实施例，都属于本申请的保护范围。
请参阅图1至图2，图1为本申请实施例提供的电子设备的第一结构示意图，图2为本申请实施例提供的电子设备的第二结构示意图。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3所示，图3为图1所示电子设备的爆炸结构示意图。电子设备20可包括第一载体100、第二载体200和柔性屏组件300。第一载体100、第二载体200可滑动的连接以使得第一载体100和第二载体200在彼此靠近或彼此远离的方向上相对运动，从而可以实现在展开状态和收拢状态之间的切换。其中，收拢状态可以参阅图1，即第一载体100和第二载体200在彼此靠近的方向上相对运动而最终形成的状态。其中，展开状态可以参阅图2，即第一载体100和第二载体200在彼此远离的方向上相对运动而形成的状态。
可以理解的是，第一载体100和第二载体200可以进行相对运动以实现电子设备20的纵向拉伸。其中，纵向抽拉指的是沿垂直于柔性屏组件300的显示方向进行抽拉的方式。如此，可以对电子设备20的屏幕显示区域的大小进行自由调节，在需要使用大屏幕时可以扩展电子设备20的显示部分与提高用户的操作体验，同时，在不需要使用大屏幕时，可以不对显示部分进行扩展，从而使得整机尺寸较小，方便携带。
需要说明的是，第一载体100和第二载体200的展开状态可以有多种，诸如第一载体100和第二载体200在彼此远离方向的最大运动距离是H，第一载体100和第二载体200可以在收拢状态进行相互远离的运动，以达到四分之一H、二分之一H、四分之三H等距离形成不同距离的展开状态。可以将距离逐渐边远的状态依次定义为第一展开状态、第二展开状态、第三展开状态等。
还需要说明的是，当第一载体100和第二载体200处于第一展开状态时，诸如第一载体100和第二载体200处于第一展开状态所相对远离运动的距离为四分之一H，第一载体100和第二载体200仍然可 以进行相互远离运动，以达到第二展开状态，诸如第一载体100和第二载体200处于第二展开状态所相对远离运动的距离为二分之一H。
可以理解的是，本申请实施例第一载体100和第二载体200的一种或多种展开状态仅为举例说明，并不构成对本申请实施例第一载体100和第二载体200的展开状态的限制。
柔性屏组件300的一端与第一载体100固定连接，柔性屏组件300的另一端与第二载体200固定连接。第一载体100和第二载体200可以对柔性屏组件300起到支撑作用。第一载体100和第二载体200在相互运动过程中可以带动柔性屏组件300一起运动，或者说驱动柔性屏组件300运动，从而可以调节柔性屏组件300的长度，进而可以改变电子设备的显示区域的大小。
当第一载体100和第二载体200在彼此靠近的方向相对运动时，第一载体100和第二载体200可以驱动柔性屏组件300的一部分收纳于电子设备20内部，诸如电子设备20的第一外壳800内。当第一载体100和第二载体200在彼此远离的方向相对运动时，第一载体100和第二载体200可以驱动柔性屏组件300的一部分从电子设备20内部伸出。
其中，第一外壳800可以盖设在第一载体100的周缘，第二外壳900可以盖设在第二载体200的周缘。
需要说明的是，柔性屏组件300在运动过程中，尤其是第一载体100和第二载体200在彼此靠近的方向上相对运动时，柔性屏组件300会在外力的作用下而形成折叠、卷曲等变形而与电子设备20的第一外壳800抵接，进而产生摩擦力，影响柔性屏组件300在运动过程中的顺畅度。而且还需要说明的是，柔性屏组件300长期与电子设备20的第一外壳800形成摩擦力还容易损坏柔性屏组件300，降低柔性屏组件300的寿命。
基于此，本申请实施例第一载体100和第二载体200在运动过程中，可以通过多个传动结构来实现对柔性屏组件300的实时传动，以防止柔性屏组件300在运动过程中因外力作用而形成折叠、卷曲等变形而与电子设备20的第一外壳800抵接，避免柔性屏组件300在运动过程中与第一外壳800形成摩擦力，提高柔性屏组件300在运动过程中的顺畅度以及增加柔性屏组件300的寿命。诸如在柔性屏组件300的一部分收缩到第一载体100和第二载体200内时，可以实现对柔性屏组件300的一端的牵引，保持柔性屏组件300在收缩过程中，一直被作用力所牵引，而不易产生松散或褶皱等变形。
请参阅图4和图5，图4为图1所示电子设备的部分结构示意图，图5为图2所示电子设备的部分的第一种结构示意图。第一载体100开设有两个滑槽120，其中一个滑槽120位于第一载体100的一侧，另一个滑槽120位于第一载体100的另一侧。可以理解的是，第一载体100的一侧和第一载体100的另一侧的位置相对。需要说明的是，第一载体100所开设滑槽120的个数并不限于两个。第一载体100仅在其中一侧开设一个滑槽120也是可以的。下面以第一载体100开设两个滑槽120为例进行说明。
第一载体100和第二载体200可以通过传动结构实现相互运动，以保持对柔性屏组件300的张力。第一载体100和第二载体200相互运动的传动结构可以包括两个运动件和两个传动带。比如传动结构可以包括第一运动件140、第二运动件160、第一传动带420和第二传动带440。第一运动件140设置在一个滑槽120内，第二运动件160设置在另一个滑槽120内，第一运动件140可以在一个滑槽120内运动，第二运动件160可以在另一个滑槽120内运动，以驱动第一载体100和第二载体200进行相对运动。第一传动带420的一端与第一载体100的连接，第一传动带420的另一端与柔性屏组件300的另一端固定连接，且第一传动带420弯曲(比如弯曲180度)绕设在第一运动件140上；第二传动带440的一端与第一载体100固定连接，第二传动带440的另一端与柔性屏组件300的另一端连接，且第二传动带440弯曲(比如弯曲180度)绕设在第二运动件160上，当第一运动件140和第二运动件160运动以驱动第一载体100和第二载体200在相互靠近的方向运动时，第一传动带420围绕第一运动件140运动且第二传动带440围绕第二运动件160运动，以共同牵引柔性屏组件300运动。
结合图3所示，柔性屏组件300可以包括柔性屏320和支撑片340。柔性屏320可以理解为柔性显示屏。支撑片340可以采用金属制成，诸如支撑片采用钢片，支撑片340设置在柔性屏320的非显示面，对柔性屏320起到承载作用。第一传动带420的另一端和第二传动带440的另一端与支撑片340连接，比如可以采用焊接的方式实现。
第一传动带420和第二传动带440可以为钢丝绳，钢丝绳的一端焊接在第一载体100上，钢丝绳的 另一端焊接在柔性屏组件300的支撑片340)。钢丝绳可以为圆柱形结构，圆柱形结构的钢丝绳相对于带状结构的钢丝绳，圆柱形结构的钢丝绳可以减少钢丝绳与第一运动件140和第二运动件160之间的接触面积，进而减少钢丝绳与第一运动件140和第二运动件160相对运动过程中的摩擦力，可以延长第一传动带420和第二传动带440的使用寿命。
可以理解的是，第一载体100和第二载体200在相互靠近的方向运动时，第一传动带420和第二传动带440会共同拉着柔性屏组件300也朝第一载体100和第二载体200的相互靠近的方向运动，使得柔性屏组件300的一部分可以回收至电子设备20的内部，以减少电子设备20的整机尺寸。而且第一传动带420和第二传动带440共同对柔性屏组件300的另一端进行牵引，避免了柔性屏组件300在运动过程中与电子设备20的第一外壳800摩擦而容易损坏。此外，本申请实施例将第一传动带420与设置在第一载体100一侧的第一运动件140连接，第二传动带440与设置在第一载体100另一侧的第二运动件160连接，可以在第一传动带420和第一传动带420之间限位出收纳空间，该收纳空间可以用于收纳电子设备20的其他器件，诸如电池或电路板。相对于直接将传动结构和/或驱动结构设置在电子设备20的中部位置，本申请实施例的器件布局设计可以使得电子设备20内部的器件更加紧凑。
请参阅图5至图8，图6为图5所示电子设备中A区域的放大结构示意图，图7为图5所示电子设备中第一运动件、第一传动带和第一驱动机构的结构示意图，图8为图7所示第一运动件、第一传动带和第一驱动机构的爆炸结构示意图。
其中，第一运动件140的表面凸出设置有限位部142，第一传动带420绕设在第一运动件140的限位部142上。第二运动件160的表面也凸出设置有限位部142，第二传动带440绕设在第二运动件160的限位部142上。当第一运动件140和第二运动件160分别在滑槽120内朝第一载体100和第二载体200相互远离的方向运动时，柔性屏组件300被第二载体200推开，此时柔性屏组件300牵引着第一传动带420和第二传动带440一起朝第一载体100和第二载体200相互远离的方向运动，第一传动带420在运动的同时围绕位于第一运动件140上的限位部142运动，第二传动带440在运动的同时围绕位于第二运动件160上的限位部142运动，柔性屏组件300在第二载体200、第一传动带420和第一传动带420的共用作用下，将柔性屏组件300的一部分从电子设备20的内部延伸至电子设备20的外部。可以理解的是，在柔性屏组件300接收到第二载体200对其施加的推力时，第一传动带420和第二传动带440逐渐减小对柔性屏组件300的拉力，使得柔性屏组件300的一部分得以展开至电子设备20的外部。
当第一运动件140和第二运动件160分别在滑槽120内朝第一载体100和第二载体200相互靠近的方向运动时，位于第一运动件140上的限位部142在运动的同时带动第一传动带420围绕位于第一运动件140上的限位部142运动，位于第二运动件160上的限位部142在运动的同时带动第二传动带440围绕位于第二运动件160上的限位部142运动，第一传动带420和第二传动带440在运动的同时共同牵引柔性屏组件300运动，以使得柔性屏组件300的一部分从电子设备20的外部回收至电子设备20的内部。可以理解的是，如果没有第一传动带420和第二传动带440的牵引，柔性屏组件300会产生变形而与第一外壳800抵接，进而使得柔性屏组件300与第一外壳800的内壁之间会产生摩擦力而损坏柔性屏组件300。
在一些实施例中，一个限位部142可以设置有一个限位槽，第一传动带420可以在其中一个限位槽内运动，第二传动带440可以在另一个限位槽内运动，限位槽可以对第一传动带420和第二传动带440进行限位，使得第一传动带420和第二传动带440在运动过程中不会脱离至限位部142外。
如图6至图8所示，一个限位部142的外表面可以套设有一个滚轮180，滚轮180可以相对于限位部142转动。第一传动带420可以绕设在一个滚轮180上，第二传动带440可以绕设在另一个滚轮180上。第一传动带420在围绕滚轮180运动的过程中可以带动滚轮180围绕限位部142转动，相对于直接围绕限位部142转动，在限位部142上增设滚轮180可以减少对第一传动带420的摩擦，使得第一传动带420运动起来更加顺畅，也可以减少第一传动带420的磨损。同样地，第二传动带440在围绕另一个滚轮180运动的过程中可以带动另一个滚轮180围绕另一个限位部142转动，相对于直接围绕另一个限位部142转动，在另一个限位部142上增设滚轮180可以减少对第二传动带440的摩擦，使得第二传动带440运动起来更加顺畅，也可以减少第二传动带440的磨损。
为了增加第一传动带420和第二传动带440在运动过程中的稳定性，还可以在滚轮180上设置限位 槽182，第一传动带420可以在其中一个限位槽182内运动，第二传动带440可以在另一个限位槽182内运动，限位槽182可以对第一传动带420和第二传动带440进行限位，使得第一传动带420和第二传动带440在运动过程中不会脱离至限位部142外。
需要说明的是，在驱动柔性屏组件300的整个运动过程中，采用第一运动件140、第二传动件240、第一传动带420和第二传动带440之间的相互作用，使得柔性屏组件300始终处于被限位的状态，或者说柔性屏组件300始终具有第一运动件140、第二传动件240、第一传动带420和第二传动带440之间的相互作用的张力，还可以理解为第一运动件140、第二传动件240、第一传动带420和第二传动带440的相互作用以一直对柔性屏组件300的一端具有牵引的作用力，以牵引柔性屏组件300运动。从而可以柔性屏组件300不会轻易的因外力作用而形成、卷曲等变形形态。进而就避免柔性屏组件300与电子设备20的外壳结构诸如第一外壳800抵接，从而提高柔性屏组件300的运动顺畅度。再者，本申请实施例保持柔性屏组件300收缩到第一载体100和第二载体200的运行过程中的牵引力，避免其与电子设备20的外壳结构诸如第一外壳800抵接，还可以对柔性屏组件300起到保护作用，提高柔性屏组件300的寿命。
可以采用手动的方式驱动第一运动件140和第二运动件160分别在滑槽120内运动。诸如施加相反的作用力在第一载体100和第二载体200上，可以将作用力作用到第一运动件140和第二运动件160上，以驱动第一运动件140和第二运动件160在滑槽120内运动，使得第一载体100和第二载体200在相互远离的方向上运动，且使得柔性屏组件300运动，以增加显示区域。再比如施加相对的作用力在第一运动件140和第二运动件160上，第一运动件140和第二运动件160可以将作用力传动到第一传动带420和第二传动带440上，以驱动第一传动带420和第二传动带440分别围绕限位部142运动，使得第一载体100和第二载体200在相互靠近的方向上运动，且使得柔性屏组件300运动，以减小柔性屏组件300的显示区域。
也可以采用电动的方式驱动第一运动件140和第二运动件160分别在滑槽120内运动。若采用电动的方式驱动第一运动件140和第二运动件160可在滑槽120内运动，则电子设备还可以包括驱动机构，诸如马达、齿轮组等结构。
例如，请参阅图5至图8，电子设备20还可以包括第一驱动机构520和第二驱动机构540，第一驱动机构520与第一运动件140连接，第二驱动机构540与第二运动件160连接，诸如第一驱动机构520可以与第一运动件140上的固定部144连接，第二驱动机构540可以与第二运动件160上的固定部144连接。第一驱动机构520可以驱动第一运动件140运动，第二驱动机构540可以驱动第二运动件160运动。
第一驱动机构520可以包括相互连接的驱动组件522和传动组件524，传动组件524与第一运动件140连接，驱动组件522可以驱动传动组件524运动，传动组件524在运动的过程中带动第一运动件140一起运动。其中，传动组件524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。比如，传动组件524包括基座5242，传动丝杆5244和连接件5246，基座5242设置在第一载体100上，传动丝杆5244与基座5242可转动连接，比如传动丝杆5244可以通过与嵌入设置在基座5242上的轴承连接，进而实现传动丝杆5244可相对于基座5242转动。传动丝杆5244还与驱动组件522连接，驱动组件522于驱动传动丝杆5244相对于基座5242转动。连接件5246套设于传动丝杆5244上且连接件5246与传动丝杆5244传动连接，连接件5246还与第一运动件140连接，连接件5246在传动丝杆5244的带动下进行往复运动，进而带动第一运动件140进行往复运动，第一运动件140进行往复运动时，第二载体200跟随第一运动件140进行往复运动。
基座5242还设置有凹槽5242a，连接件5246设置在传动丝杆5244上且位于凹槽5242a内，凹槽5242a可以对连接件5246的运动起导向定位的作用。
可以理解的是，本申请实施例中的驱动组件522提供主动驱动效果，第一运动件140和第一传动带420为联合从动机构，在驱动组件522的主动驱动下进行联动运动，使得第一运动件140的运动距离、第一传动带420的运动距离和柔性屏组件300的展开长度或回收长度相等，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)，可以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。
结合图9所示，图9为图8所示第一运动件、第一传动带和第一驱动机构中连接件的结构示意图。连接件5246设置有通孔5246a，通孔5246a的孔壁上设置有传动螺纹，该传动螺纹与传动丝杆5244上的螺齿相啮合，使得传动丝杆5244转动时通过通孔5246a上的传动螺纹带动连接件5246沿平行与第一载体100的方向做直线运动。可以理解的是，传动丝杆5244的转动可以转化为连接件5246的直线运动。连接件5246还设置有卡槽5246b，卡槽5246b与固定部144卡接以使连接件5246与第一运动件140连接。当然，也可以采用其他方式(比如焊接、粘接等)实现连接件5246和第一运动件140的连接。
请参阅图7和图8，驱动组件522可以包括第一驱动模组5222和第一减速模组5224，第一驱动模组5222与第一减速模组5224连接，第一减速模组5224与传动丝杆5244传动连接。比如，第一减速模组5224可以为减速箱，减速箱与第一驱动模组同轴连接，减速箱可以对第一驱动模组5222进行减速，以增大扭矩。第一减速模组5224可以通过齿轮组与传动丝杆5244连接，比如第一减速模组5224的输出轴连接有第一齿轮562，传动丝杆5244连接有第二齿轮564，第二齿轮564与第一齿轮562均与第三齿轮566啮合以实现第一减速箱5224与传动丝杆5244的传动连接。
如图10所示，图10为图8所示第一运动件、第一传动带和第一驱动机构中第一驱动机构的第二种结构示意图。为了进一步增加驱动组件522的输出功率，以增加传动丝杆5244和连接件5246的输出推力，本申请实施例的驱动组件522还可以包括相互连接的第二驱动模组5226和第二减速模组5228，第二减速模组5228与第一减速模组5224传动连接。比如，第二减速模组5228设置有第四齿轮568，第二减速模组5228的第一齿轮562与第四齿轮568之间均与第五齿轮569啮合以实现第二减速模组5228与第一减速模组5224传动连接。第二减速模组5228上的第四齿轮568通过第五齿轮569将扭矩传递到第一减速模组5224的第一齿轮562上，两个减速模组的输出扭矩进行叠加。叠加后的扭矩再通过第二齿轮564传递到传动丝杆5244，从而驱动传动丝杆5244旋转。相比于只有一个驱动模组和一个减速模组，本申请实施例所采用的两个驱动模组和两个减速模组可以使得传动丝杆5244和连接件5246所产生的推力增加80％左右。
需要说明的是，第一齿轮562、第三齿轮566、第四齿轮568和第五齿轮569所组成的4个齿轮副，都是半刚性连接。可以理解的是，每个齿轮副中至少有一个齿轮的材料是弹性模量较小的材料(如塑胶)所制成的，以避免微观上不同步造成的冲击问题。
请参阅图11，图11为图8所示第一运动件、第一传动带和第一驱动机构中第一驱动机构的第三种结构示意图。驱动组件522也可以包括两个驱动模组和一个减速模组，比如驱动组件522可以包括第一驱动模组5222、第一减速模组5224和第二驱动模组5226，第一驱动模组5222与第二驱动模组5226串联连接，第一减速模组5224可以与第一驱动模组5222或第二驱动模组5226同轴连接。比如，第一驱动模组5222的驱动轴和第二驱动模组5226的驱动轴通过联轴器5229连接以使得第一驱动模组5222与第二驱动模组5226串联连接。两个驱动模组串联后通过第一减速模组5224减速，增大扭矩，第一减速向5224通过第一齿轮562和第二齿轮564同步驱动传动丝杆5244旋转。其中，联轴器5229采用弹性模量较小的材料(如塑胶)制成，使得两个驱动模组启动时的微小不同步所产生的作用力能够被弹性的联轴器5229吸收。此时，第一驱动模组5222的输出端和第二驱动模组5226的输入端连接。
结合图12和图13所示，图12为图11所示第一驱动机构的部分爆炸结构示意图，图13为图11所示的第一驱动机构中联轴器的结构示意图。第一驱动模组5222的驱动轴和第二驱动模组5226的驱动轴的结构均为半圆柱结构，其截面形成大致呈D形。联轴器5229设置有连接孔5229a，连接孔5229a的形状与第一驱动模组5222的驱动轴和第二驱动模组5226的驱动轴的结构相适配，且连接孔5229a的尺寸略大于第一驱动模组5222的驱动轴和第二驱动模组5226的驱动轴的尺寸，使得第一驱动模组5222的驱动轴和第二驱动模组5226的驱动轴穿设至连接孔5229a内，联轴器5229和第一驱动模组5222的驱动轴和第二驱动模组5226的驱动轴之间存在间隙，该间隙可以吸收两个驱动模组启动时的微小不同步所产生的作用力。
在一些实施例中，第一驱动模组5222和第二驱动模组5226也可以串联连接后通过齿轮与减速齿轮啮合以实现两个驱动模组和一个减速模组相互连接。此时，第一驱动模组5222的输入端和第二驱动模组5226的输入端连接，即第一驱动模组5222和第二驱动模组5226为相对串联的连接方式。
第二驱动机构540的结构可以与第一驱动机构520的结构相同，比如第二驱动机构540也可以包括 相互连接的驱动组件542和传动组件544，传动组件544与第二运动件160连接，驱动组件542可以驱动传动组件544运动，传动组件544在运动的过程中带动第二运动件160一起运动。其中，第二驱动机构540中的驱动组件542和传动组件544可以为如上所述驱动组件和传动组件中的任一种结构，在此不再赘述。比如驱动组件542可以包括相互连接的第一驱动模组5422和第一减速模组5424。其中，第一驱动模组5422的结构和第一驱动机构520的第一驱动模组5222的结构相同，第一减速模组5424的结构和第一驱动机构520的第一减速模组5224的结构相同。当然，第二驱动机构540的结构也可以与第一驱动机构520不同，比如第二驱动机构540可以为齿轮组传动或其他方式的传动，而不限于上述的丝杆传动。
请参阅图5和图7，第一载体100设置有多个第一插接部110，相邻两个第一插接部110之间设置有第一插槽130，第二载体200设置有多个第二插接部210，相邻两个第二插接部210之间设置有第二插槽230，当第一载体100与第二载体200相互连接时，第一插接部110容置在第二插槽230内且第一插接部110可在第二插槽230内运动，第二插接部210容置在第一插槽130内且第二插接部210可在第一插槽130内运动。
请继续参阅图5，第二载体200还设置有限位件220，柔性屏组件300弯曲(比如弯曲180度)绕设在限位件220上。当第一运动件140和第二运动件160运动以驱动第一载体100和第二载体200朝相互远离的方向运动时，限位件220跟随第二载体200朝第一载体100和第二载体200相互远离的方向运动，限位件220运动的同时会推动柔性屏组件300朝电子设备20的外部运动，实现柔性屏组件300的展开功能。其中，限位件220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220也可以为不规则形状，比如限位件220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220可以为独立于第二载体200的额外设置的部件，限位件220也可以为第二载体200的其中一部分。
如图14所示，图14为图3所示电子设备中限位件的结构示意图。限位件220可以包括转轴222和滚筒224，所述滚筒224套设在转轴222的外表面且与转轴222可转动连接(比如通过滚珠连接)，使得滚筒224可以围绕转轴222转动。柔性屏组件300绕设在滚筒224上，柔性屏组件300在运动的同时可以带动滚筒224围绕转轴222转动，可以减小柔性屏组件300与限位件220之间的摩擦力，可以延长柔性屏组件300的使用寿命，并且还可以使得柔性屏组件300运动起来更顺畅。
下面举例来说明电子设备20中第一载体100和第二载体200相互运动以带动柔性屏组件300运动进而改变柔性屏组件300的显示区域。请参阅图1、图2、图3、图4、图6和图7，图1、图3和图6示意出电子设备20的第一载体100和第二载体200处于收拢状态。可以采用电动驱动的方式驱动第一载体100和第二载体200进行相互远离的运动以切换至展开状态，图2、图4和图7示意出电子设备20的第一载体100和第二载体200处于展开状态。
第一驱动模组5222通过第一减速模组5224减速以增大扭矩，通过第一齿轮562和第二齿轮564驱动传动丝杆5244旋转，连接在传动丝杆5244上的连接件5246将传动丝杆5244的旋转运动转化为直线运动，连接件5246与第一运动件140(第二运动件160)配合，带动第二载体200一起运动，第一运动件140和第二运动件160运动时又带动第二插接部210以及安装在第二载体200上的限位件220运动。第二载体200运动的过程中，限位件220推动柔性屏组件300往外运动，即实现将柔性屏组件300展开的功能。当第一驱动模组5222的驱动反向反转，第一运动件140和第二运动件160运动以驱动第一载体100和第二载体200朝相互靠近的方向运动，此时设置在第一载体100上的第一插接部110朝靠近限位件220的方向运动，设置在传动丝杆5244上的连接件5246朝远离限位件220的方向运动，两者运动速度相同，方向相反。连接在第一运动件140上的第一传动带420和连接在第二运动件160上的第二传动带440分别通过滚轮180转换运动方向，拉动柔性屏组件300中的支撑片340，因此柔性屏组件300中的支撑片340朝远离限位件220方向运动的速度和第一插接部110朝靠近限位件220的方向运动的速度一致，当第一运动件140和第二运动件160收拢到第一预设位置时，柔性屏320也被支撑片340带到第二预设位置，实现柔性屏组件300收拢的功能。
需要说明的是，运动件的个数可以为一个，传动带的个数也可以为一个，比如第二载体200的一侧设置第一运动件140，第二载体200的另一侧未设置有运动件。第一运动件140与第一传动带420连接，第一运动件140的结构以及与其他结构的连接关系和第一传动带420的结构以及与其他结构的连接关系 如上所述。当第一运动件140运动以驱动第一载体100和第二载体200在相互靠近的方向运动时，第一传动带420围绕第一运动件140运动以牵引柔性屏组件300运动。
如图6、图7和图15所示，图15为图2所示电子设备的部分第二种结构示意图。第一驱动机构520设置在第一载体100的一侧，第二驱动机构540设置在第一载体100的另一侧，且与第一驱动机构520间隔设置，第一驱动机构520和第二驱动机构540之间可以限定出收纳空间150，以收纳电子设备20的预设器件。第一驱动机构520和第二驱动机构540用于共同驱动第一载体100和第二载体200相互运动以带动柔性屏组件300运动。该预设器件可以包括电池600，电池600可以容置在收纳空间150内，本申请实施例的第一驱动机构520和第二驱动机构540的设置位置可以使得电子设备20内部预留出更多的空间来设置预设器件。电子设备20还可以包括电路板700，电路板700包括间隔设置的第一凸出部720和第二凸出部740，第一凸出部720和第二凸出部740位于收纳空间150内，且第一凸出部720的一端的端部与第一驱动机构520的第一驱动模组5222相邻设置且第一驱动模组5422的高度大于第一凸出部720的高度，以在第一凸出部720预留出空间来安装电子设备20的其他器件(诸如半导体、电容或电阻等)。第二凸出部740的一端的端部与第二驱动机构540的第一驱动模组5422相邻设置且第一驱动模组5422的高度大于第二凸出部740的高度，以在第二凸出部740预留出空间来安装电子设备20的其他器件(诸如半导体、电容或电阻等)。电池600的一部分位于第一凸出部720和第二凸出部740之间，电池600的另一部分位于第一驱动机构520的第一驱动模组5222和第二驱动机构540的第一驱动模组5422之间。本申请实施例的第一驱动机构520和第二驱动机构540的设置位置可以使得电子设备20内部预留出更多的空间来设置预设器件，而且第一驱动机构520与第一凸出部720相邻设置，第二驱动机构540与第二凸出部740也可以便于第一驱动机构520和第二驱动机构540与电路板700之间的电性连接，可以避免由于与电路板700与第一驱动机构520和第二驱动机构540之间的距离过远而导致电性连接线过长或者过于曲折的情况发生。
需要说明的是，电子设备20的抽拉方式并不限于此。例如，请参阅图16和17，图16为本申请实施例提供的电子设备的第三种结构示意图，图17为本申请实施例提供的电子设备的第四种结构示意图。本申请实施例提供的电子设备诸如电子设备40的抽拉方式可以为横向抽拉，电子设备40可以包括第一载体41、第二载体42和柔性屏组件43，第一载体41和第二载体42用于共同承载电子设备40，第一载体41和第二载体42可以相对运动以使得柔性屏组件43的一部分展开于电子设备40外部或收拢于电子设备40内部。其中，横向抽拉指的是沿平行于柔性屏组件43的显示方向进行抽拉的方式。
以上对本申请实施例提供的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。
