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做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。请参阅图1至图4，图1为本申请实施例提供的显示装置的第一结构示意图，图2为本申请实施例提供的显示装置的第二结构示意图，图3为图1所示显示装置沿P1-P1方向的第一种剖视图，图4为图2所示显示装置沿P2-P2方向的第一种剖视图。显示装置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和图2，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3和4，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显示装置20的横向拉伸。其中，横向抽拉指的是沿平行于柔性屏组件300的显示方向进行抽拉的方式。如此，可以对显示装置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显示装置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。
本申请实施例中，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，比如柔性屏组件300的另一端可以直接与第二载体200固定连接，柔性屏组件300的另一端也可以通过连接件(诸如传动带)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处于收拢状态时，柔性屏组件300的一部分直接裸露在显示装置20的外部，柔性屏组件300的一部分收纳于显示装置20的内部，或者说柔性屏组件300的一部分位于显示装置20的第一侧，柔性屏组件300的一部分位于显示装置20的第二侧，即在收拢状态下柔性屏组件300同时位于显示装置20的正面和背面。当第一载体100和第二载体200从收拢状态相对运动而展开时，柔性屏组件200中原先收纳在显示装置20内部的部分运动至显示装置20的外部，使得整个柔性屏组件200均裸露在显示装置20的外部。
可以理解的是，当第一载体100和第二载体200处于收拢状态时，柔性屏组件300显示区域的一部分位于显示装置20的外表面可以显示画面，柔性屏组件300显示区域的另一部分位于显示装置20的内部，可以不显示画面。而当第一载体100和第二载体200处于展开状态时，柔性屏组件300显示区域均位于显示装置20的外表面，可以共同显示画面。
柔性屏组件300可以包括相互连接的主体部分310和扩展部分320，主体部分310可以固定在第一载体100的外表面，诸如采用胶层粘接的方式将主体部分310粘接在第一载体100的外表面。从而在使用显示装置20过程中，主体部分310可以始终保持在第一载体100的外表面，以确保显示装置20无论在哪一种状态下至少可以通过主体部分310显示画 面。
扩展部分320可以设置于第二载体200、且扩展部分320能够跟随第一载体100和第二载体200的相互运动而运动以收纳于第二载体200或伸出至所述第二载体200的外表面。当扩展部分320位于第二载体200内部时，第一载体100和第二载体200处于收拢状态，第一载体100和第二载体200在相互远离的方向运动可以驱动扩展部分320从第二载体200内部伸出至第二载体200外表面。可以与主体部分310共同显示画面。当扩展部分320位于第二载体200外表面时，第一载体100和第二载体200处于展开状态，第一载体100和第二载体200在相互靠近的方向运动可以驱动扩展部分320从第二载体200外表面收拢到第二载体200内部。
可以理解的是，柔性屏组件300的主体部分310可以采用胶层等连接结构直接固定连接到第一载体100的外表面，可以保持主体部分310的稳定性、平整性。而柔性屏组件300的扩展部分320会跟随第一载体100和第二载体200的运动而运动，不能够像主体部分310一样采用胶层等连接结构直接固定连接到第二载体200上。在扩展部分320运动的过程中，容易导致扩展部分320的形状产生变化，诸如导致扩展部分320起拱，从而会影响柔性屏组件300的显示效果。
需要说明的是，组装生产过程中需要预留公差，在实际装配过程中，会存在公差的差异，导致起拱量产生变化。导致显示装置的一致性差。
还需要说明的是，柔性屏组件300可以运动，第一载体100及第二载体200可以运动，即本申请实施例显示装置20具有多个可以运动的部件。从而容易导致柔性屏组件300运动过程中产生的间隙越来越大。再考虑到柔性屏组件300老化的问题，同样会导致柔性屏组件300运动过程中产生的间隙越来越大。尤其是会导致柔性屏组件300的扩展部分320在柔性屏组件300厚度方向与第二载体200的间距变大。
基于此，本申请实施例的显示装置20还包括支撑件400和多个磁性件500，支撑件400设置于扩展部分320的非显示面，可以对扩展部分320进行支撑，多个磁性件500可以在扩展部分320伸出第二载体200外时，与支撑件400配合以限制扩展部分320与第二载体200之间的间距，以使得扩展部分320与第二载体200之间的间距保持在预设距离内，防止由于扩展部分320与第二载体200之间的间距过大而导致扩展部分320起拱，尤其是可以防止扩展部分320伸出第二载体200外表面时起拱。
可以理解的是，支撑件400和一个或多个磁性件500相互配合可以使得扩展部分320 在运动过程中与第二载体200的间距较小或者是通过支撑件400紧贴着第二载体200的表面运动，第二载体200可以在扩展部分320的运动过程中为扩展部分320提供支撑，从而防止扩展部分320的一部分没有得到第二载体200的支撑而起拱或者说起褶皱。
需要说明的是，支撑件400可以铺设在扩展部分320的整个非显示面，也可以铺设在扩展部分320的一部分非显示面，还可以铺设在柔性屏组件300的整个非显示面。
请参阅图5和图6，图5为本申请实施例提供的显示装置中柔性屏组件和支撑条配合的示意图，图6为图5所示A部分的放大图。支撑件400可以由多个条状的支撑条组合形成，每一条支撑条均具有磁性，可以被磁铁所吸引，诸如支撑条可以采用可被磁铁吸引的金属材质或合金材质制成，诸如支撑条可以采用由铁、镍、钴中的一种或多种材质制成。多条支撑条沿柔性屏组件300运动方向间隔排布在扩展部分320的非显示面，还可以排布在主体部分310的非显示面。诸如多个支撑条等间隔排布。支撑件400还可以采用一具有磁性的网状的支撑件，网状的支撑件可以铺设于扩展部分320的整个非显示面，还可以铺设于主体部分310的整个非显示面。支撑件400还可以采用一整块具有磁性的支撑板或者多个具有磁性的支撑块，支撑块可以设置于扩展部分320的非显示面的预设位置。需要说明的是，多条支撑条还可以对柔性屏组件300起到支撑作用，网状的支撑件也可以对柔性屏组件300起到支撑作用。
可以理解的是，支撑条为条形结构，多条支撑条沿着柔性屏组件300弯折弧的轴向分布，不会增加柔性屏组件300的弯折反弹力。而网状的支撑件铺设于柔性屏组件300的非显示面，在柔性屏组件300弯折弧的轴向和径向均有分布，会额外增加柔性屏组件300的弯折反弹力。而且还需要说明的是，在实际应用中，若网状的支撑件的厚度较薄则对柔性屏组件300所起到的支撑作用较差，若网状的支撑件的厚度较厚则导致柔性屏组件300不易弯折。支撑块对柔性屏组件300起不到有效的支撑作用。本申请实施例下面以支撑件400为多条支撑条为例进行说明。
本申请实施例支撑件400和磁性件500能够相互作用诸如相互吸引来限制扩展部分320伸出至第二载体200外表面时与第二载体200的间距。诸如磁铁可以吸引与其靠近的一个或多个支撑条，磁铁包括不限于钕磁铁，普通磁铁，柔性磁铁或者电磁铁。磁铁所吸引的支撑条可以是位于磁铁正上方的支撑条，也可以是位于磁铁正上方靠近磁铁的支撑条。
如图7所示，图7为本申请实施例提供的显示装置中第一载体和第二载体的配合结构示意图。第二载体200可以包括多个平直部210和多个弯折部220，多个平直部210相互 间隔设置，多个平直部210可以支撑扩展部分320；多个弯折部220的与多个平直部210中的一部分连接，扩展部分320可围绕多个弯折部220运动。
其中，一个或多个磁性件500的至少一部分设置在平直部210上，比如一个或多个磁性件500中的一部分可以设置在平直部210上，也可以全部磁性件500均设置在平直部210上。
如图7所示，平直部210可以设置有第一收纳槽211，比如多个平直部210中的一个设置有一个或多个第一收纳槽211，或者多个平直部210中的多个均设置有一个或多个第一收纳槽211。一个第一收纳槽211可以容置多个磁性件500中的一个或多个。诸如第二载体200可以包括十五个平直部210，其中一部分平直部210设置有一个第一收纳槽211，一部分平直部210设置有多个第一收纳槽211，一个第一收纳槽211设置有一个磁性件500或多个磁性件500。
一个或多个磁性件500中的一部分可以设置在平直部210上，另一部分可以设置在弯折部220上。例如，弯折部220可以设置有第二收纳槽221，比如多个弯折部220中的一个可以设置有一个或多个第二收纳槽221，或者多个弯折部中的多个均可以设置有一个或多个第二收纳槽221。一个第二收纳槽211可以容置多个磁性件500中的一个或多个。诸如，第二载体200可以包括四个弯折部220，一个弯折部220可以与三个平直部210连接，相邻的两个弯折部220之间具有开口222，多个平直部210中的一部分可以相互连接并位于一个开口222内。一个弯折部220可以设置有一个第二收纳槽221，当然，一个弯折部220也可以设置有多个第二收纳槽221。一个第二收纳槽211可以容置有一个或多个磁性件500。
在实际应用中，由于柔性屏组件300的本身特性，扩展部分320在弯曲位置相比于平直位置，其反弹应力较大，比较容易起拱。本申请实施例中，设置于第一收纳槽211的磁铁的尺寸小于设置在第二收纳槽221的磁铁的尺寸，即与扩展部分320的弯曲位置相对应的磁铁的尺寸大于与扩展部分320的平直位置相对应的磁铁的尺寸，这样可以增加对支撑件400中与扩展部分320的弯曲位置相对应的部分的磁性作用力，克服扩展部分320本身的弯曲起拱应力，保证扩展部分320在弯曲圆弧位置不起拱，以便带来更好的用户体验。
结合图7和图8所示，图8为图7所示第一载体和第二载体中带动件的结构示意图。显示装置20还可以包括带动件600，带动件600设置在第二载体200上，带动件600可与第二载体200一起相对于第一载体100运动，扩展部分320可围绕带动件600运动。其中，带动件600位于扩展部分320的弯曲位置且与支撑件400抵持，使得带动件600可以与支 撑件400一起支撑扩展部分320的弯折位置。
多个弯折部220均与带动件600连接，扩展部分320可以围绕弯折部220和带动件600运动。当第一载体100和第二载体200在朝相互远离的方向运动时，带动件600可以带动扩展部分320的至少一部分和支撑件400的至少一部分一起沿着带动件600的外表面逐渐转动至第二载体200的外表面，此时扩展部分320的至少一部分裸露在第二载体200的外表面，扩展部分320中裸露至第二载体200外表面的部分可以与主体部分310一起显示信息，相对于仅用主体部分310显示显示，可以增加显示面积。当第一载体100和第二载体200在朝相互靠近的方向运动时，可以使得扩展部分320朝靠近第一载体100的方向沿带动件600的外表面逐渐转动至第二载体200的内部，使得扩展部分320的至少一部分收纳进第二载体200内，扩展部分320运动过程中会带动带动件600和第二载体200朝靠近第一载体100的方向运动，进而缩短带动件600和第二载体200与第一载体100之间的距离。
在其他一些实施例中，带动件600设置有限位结构，限位结构可以与支撑件400配合以限制扩展部分320与带动件600之间的间距，防止扩展部分320的弯曲位置起拱。其中，限位结构可以包括一个或多个磁铁，一个或多个磁铁可以围设在带动件600的外表面。
例如，如图8所示，带动件600可以包括转轴610和多个滚筒620，所述多个滚筒620相互间隔设置，一个或多个磁铁(图中并未示出)围设在转轴610的周缘外表面且位于相邻两个滚筒620间隔位置之间。其中，限位结构可以与滚筒620的外表面齐平，使得带动件600可以与限位结构共同形成一个平整的支撑面，以对扩展部分320进行支撑。
可以理解的是，由于柔性屏组件300本身的特性，扩展部分320在弯曲位置或者说圆弧区域的反弹应力最大，相比于平直位置或者说平直段，其起拱的程度也比较大。在带动件600设置有限位结构可以加强对扩展部分320的弯曲区域的吸引作用力，以克服扩展部分320本身弯曲的起拱应力，确保扩展部分320在弯曲区域不起拱。
本申请实施例中，一个或多个滚筒620可以围绕转轴610转动，当扩展部分320围绕带动件600运动时可带动一个或多个滚筒620绕转轴610转动。相比于滚筒620与转轴610固定连接，本申请实施例可转动的滚筒620还可以减少对支撑件400的摩擦力。
需要说明的是，本申请实施例的带动件600的结构并不限于此。例如，如图9和图10所示，图9为图2所示显示装置沿P2-P2方向的第二种剖视图，图10为图2所示显示装置中带动件的结构示意图。带动件600也可以仅包括转轴610，转轴610的外表面设置有限位结构700，比如限位结构700可以为环形磁铁，环形磁铁套设在限位结构700的外表面， 限位结构700可以与支撑件400配合以限制扩展部分320与带动件600之间的间距。
可以理解的是，本申请实施例直接在转轴610的外圈增加环形磁铁，环形磁铁固定在转轴610上，可以跟着转轴610转动，与支撑件400的弯曲部分形成滚动摩擦，同时环形磁铁可以对支撑件400的弯曲部分产生磁力，用于克服扩展部分320在在转轴610弯曲位置自身产生的起拱外张力，保证扩展部分320在弯曲圆弧位置不起拱，以便带来更好的用户体验。
请继续参阅图9和图10，本申请实施例中第二载体200可以仅包括平直部210，平直部210和带动件600同时与第二载体200连接在一起。
需要说明的是，图7和图8所示的带动件600也可以采用转轴本身的直径空间，间断减胶出转轴局部避空位置，此位置支撑件400可以搭过来，由于支撑件400在垂直于柔性屏组件300的运动方向上有刚性的特性，转轴局部避空不影响支撑件400和扩展部分320绕着转轴转动和展出。图9和图10所示的带动件600相对于图7和图8所示的带动件600不需要对转轴切避空，可以将转轴缩小半径，直接在外圈增加环形磁铁，环形磁铁固定在转轴上，可以跟着转轴转动。
本申请实施例可以利用空间布局结合部分结构件的特性，在需要的位置增加相应的磁铁或加入环形磁铁，保证扩展部分320的服帖性，解决扩展部分320的起拱问题。
需要说明的是，显示装置20的抽拉方式并不限于此。例如，请参阅图11和图12，图11为本申请实施例提供的显示装置的第三种结构示意图，图10为本申请实施例提供的显示装置的第四种结构示意图。本申请实施例提供的电子设备诸如显示装置40的抽拉方式可以为横向抽拉，显示装置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用于共同承载显示装置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的一部分展开于显示装置40外部或收拢于显示装置40内部。其中，纵向抽拉指的是沿垂直于柔性屏组件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显示装置进行了详细介绍。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。
