为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。
请参阅图1和图2，图1示出了相关技术中的可折叠的电子设备1在展开状态下的主视图，图2示出了图1所示电子设备1在折叠状态下的主视图。
电子设备1包括折叠机构011、第一侧板012、第二侧板013以及柔性显示屏02。第一侧板012和第二侧板013分别连接于折叠机构011的两侧，并能够基于折叠机构011在折叠状态与展开状态之间转动。柔性显示屏02设置于第一侧板012和第二侧板013上，柔性显示屏02的可柔性形变部位021的位置与折叠机构011的位置相对应；可柔性形变部位021能够发生弯折，以使柔性显示屏02能够随第一侧板012和第二侧板013的转动而折叠或展开。
请参阅图1，在电子设备1处于展开状态时，第一侧板012和第二侧板013之间的夹角大致为180°，柔性显示屏02大致呈平板状，柔性显示屏02的可柔性形变部位021大致呈平整状。
请参阅图2，在电子设备1处于折叠状态时，第一侧板012和第二侧板013之间的夹角大致为0°，柔性显示屏02的可柔性形变部位021呈弯折状。
在电子设备1的生产及使用过程中，可能会受到外物的撞击，或者发生摔落，导致柔性显示屏02易受损。尤其是柔性显示屏02的可柔性形变部位021，因需要进行弯折，结构强度相对较低，受外力作用时更易受损。例如，在电子设备1受到外力作用时，柔性显示屏02的可柔性形变部位021与折叠机构011之间可能会发生相互碰撞，易导致可柔性形变部位021受损失效。
示例性地，请参阅图3，图3示意了图1所示电子设备1在展开状态下的局部结构示意图。柔性显示屏02朝向折叠机构011的一侧连接有支撑组件03，该支撑组件03包括两个支撑薄板031和设置于两个支撑薄板031之间的转动件032，转动件032的位置与柔性显示屏02的可柔性形变部位021的位置相对应，两个支撑薄板031可基于二者之间的转动件032相对转动，以使支撑组件03能够随柔性显示屏02同步折叠或展开。支撑组件03可对柔性显示屏02起到支撑作用和加强作用。
转动件032包括多个并排设置的条形体0321，相邻两个条形体0321之间存在间隙。 在电子设备1由展开状态转动至折叠状态的过程中，柔性显示屏02的可柔性形变部位021逐渐弯折，多个条形体0321则随之逐渐聚拢，以维持可柔性形变部位021的弯折形态。在电子设备1由折叠状态转动至展开状态的过程中，柔性显示屏02的可柔性形变部位021逐渐展平，多个条形体0321则随之逐渐展开，以维持可柔性形变部位021的平整形态。
在电子设备1受到外力作用时，可柔性形变部位021及转动件032容易与折叠机构011之间发生相互碰撞，而转动件032的条形体0321为了较好地支撑可柔性形变部位021，通常为金属材质的硬质结构，导致可柔性形变部位021易发生损坏而失效，影响电子设备1的使用寿命。
有鉴于此，本申请实施例提供一种折叠组件以及包括该折叠组件的终端设备，能够改善相关技术中柔性显示屏的可柔性形变部位受外力作用时易受损的技术问题，提高可靠性。
本申请实施例提供的终端设备属于可折叠电子设备，即能够实现折叠和展开的电子设备。该终端设备可以为手机、平板电脑、膝上型电脑(Laptop)、笔记本电脑(Notebook PC)、个人数码助理(Personal Digital Assistant，PDA)、可穿戴设备(例如手表)、车载设备、增强现实(Augmented Reality，AR)/虚拟现实(Virtual Reality，VR)设备等，但不限于此。
请参阅图4和图5，图4示出了本申请一些实施例提供的终端设备1000在展开态下的结构示意图，图5示意了图4所示终端设备1000在展开态下的局部结构示意图。本申请实施例中，以终端设备1000为手机作为示例进行介绍说明。
终端设备1000包括折叠组件100、转轴机构200、第一壳体300、第二壳体400以及折叠屏500，其中：
第一壳体300和第二壳体400通过转轴机构200转动连接；即，第一壳体300和第二壳体400可基于转轴机构200发生相对转动，以能够相对靠拢而转动至折叠态，以及能够相对远离而转动至展开态。
可以理解，第一壳体300和第二壳体400均可以为中框，具体形状和结构可以根据需要进行设置。转轴机构200可以是多种形式的结构，只要能够供与其连接的第一壳体300和第二壳体400发生相对转动即可。
折叠屏500设置于第一壳体300和第二壳体400上，能够随第一壳体300和第二壳体400的转动而折叠或展开。折叠屏500的可折叠部位510的位置与转轴机构200的位置相对应。可折叠部位510即能够发生弯折的部位，具有柔性，以使得第一壳体300和第二壳体400发生相对转动时，折叠屏500能够通过可折叠部位510发生弯折而实现折叠。在折叠屏500处于折叠态时，可折叠部位510可以呈水滴形或U形，但不限于该形状。
可以理解，折叠屏500对应于第一壳体300的屏体部位可以具有柔性，也可以为刚性；折叠屏500对应于第二壳体400的屏体部位可以具有柔性，也可以为刚性。
折叠组件100连接于折叠屏500的背面，折叠组件100即位于折叠屏500与转轴机构200之间。折叠组件100能够随折叠屏500的折叠或展开而同步折叠或展开。其中，折叠屏500的背面为朝向转轴机构200的一面，也可以视为折叠屏500的非显示 面；折叠屏500的正面为背向转轴机构200的一面，也即为折叠屏500用于显示图像的显示面。
在终端设备1000处于展开态时，折叠屏500和折叠组件100也即处于展开态，第一壳体300和第二壳体400大致处于同一平面，即第一壳体300与第二壳体400之间的夹角大致为180°。此时，折叠屏500即大致呈平整状，以使终端设备1000具有较大的显示面积。应理解，在终端设备1000处于展开态时，并非限定第一壳体300和第二壳体400之间的夹角为绝对的180°；第一壳体300和第二壳体400之间的夹角也可以大于或小于180°，但接近于180°，例如夹角的范围可以为165°至190°(例如170°、173°、175°、182°、185°等，但不限于此)，也同样能够实现折叠屏500的展开。
在终端设备1000处于折叠态时，折叠屏500和折叠组件100也即处于折叠态，第一壳体300和第二壳体400大致平行，即第一壳体300与第二壳体400之间的夹角大致为0°。此时，折叠屏500即通过其可折叠部位510折叠，以利于终端设备1000的收纳。应理解，在终端设备1000处于折叠态时，并非限定第一壳体300与第二壳体400绝对平行，第一壳体300和第二壳体400之间的夹角也可以大于0°，但接近于0°，例如夹角的范围可以为0°至15°(例如1°、2°、3°、5°、10°等，但不限于此)，也同样能够实现折叠屏500的折叠。
在一些实施例中，请参阅图4，终端设备1000可以为内折型终端设备，折叠屏500即为内折型折叠屏。在折叠屏500折叠后，折叠屏500位于折叠组件100的内侧。
当然，在其他一些实施例中，终端设备1000也可以为外折型终端设备，折叠屏500即为外折型折叠屏。在折叠屏500折叠后，折叠屏500的显示面裸露，折叠组件100位于折叠屏500的内侧。
在一些实施例中，请参阅图5，转轴机构200包括轴盖210、底座220、支撑门板230、第一摆臂240以及第二摆臂250。底座220设置于轴盖210上，底座220可为支撑门板230、第一摆臂240以及第二摆臂250提供支撑和安装。支撑门板230设置于底座220上，可用于支撑折叠屏500的可折叠部位510。第一摆臂240和第二摆臂250分别可转动地连接于底座220的两侧，以能够基于底座220转动至折叠态或展开态。第一摆臂240连接于第一壳体300，第二摆臂250连接于第二壳体400，以使第一壳体300和第二壳体400转动时带动第一摆臂240和第二摆臂250同时转动。
在终端设备1000处于展开态时，支撑门板230、第一摆臂240和第二摆臂250均可支撑折叠屏500的可折叠部位510，利于可折叠部位510稳定地处于平整状。在终端设备1000处于折叠态时，第一摆臂240和第二摆臂250可基于底座220转动并相互靠拢，支撑门板230、第一摆臂240和第二摆臂250之间即可形成容纳空间，以用于容纳弯折后的可折叠部位510。
可选地，第一摆臂240和第二摆臂250可以通过多种方式与底座220连接配合。
示例性地，底座220两侧均设有滑槽，第一摆臂240和第二摆臂250上均设有滑轨，第一摆臂240和第二摆臂250分别通过滑轨与滑槽滑动配合，以在第一摆臂240和第二摆臂250基于底座220转动的同时，滑轨沿滑槽的轨迹滑动。
示例性地，第一摆臂240和第二摆臂250也可以分别通过转轴与底座220连接， 并能够驱动支撑门板230升降。在第一摆臂240和第二摆臂250转动至展开态时，同时驱动支撑门板230上升(朝向可折叠部位510移动)以支撑可折叠部位510，在第一摆臂240和第二摆臂250转动至折叠态时，驱动支撑门板230下降(背向可折叠部位510移动)以避让弯折后的可折叠部位510。
下面，将对本申请实施例提供的折叠组件100进行介绍说明。
请参阅图5至图7，图6示出了本申请一些实施例提供的折叠组件100在展开态下的立体结构示意图，图7示出了图6所示折叠组件100在折叠态下的立体结构示意图。折叠组件100包括第一支撑件10、第二支撑件20以及折叠件30。第二支撑件20与第一支撑件10间隔设置。折叠件30设置于第一支撑件10与第二支撑件20之间。第一支撑件10和第二支撑件20能够基于折叠件30相对转动，以使折叠组件100在展开态与折叠态之间切换。也就是说，折叠件30自身可以实现弯折或折叠，使得折叠件30两侧的第一支撑件10与第二支撑件20能够以折叠件30整体作为轴进行转动。其中，折叠件30包括弹性体31，弹性体31用于缓冲外力。
第一支撑件10和第二支撑件20连接于折叠屏500的背面，能够支撑折叠屏500，可以对折叠屏500起到稳定形态的作用和加强作用。可选地，第一支撑件10和第二支撑件20可以是多种形状的片状结构、板状结构或层状结构，以便贴附于折叠屏500的背面。第一支撑件10和第二支撑件20可以采用多种硬质材质，例如可以是金属材料(例如不锈钢等)、合金等，但不限于此。第一支撑件10的形状与第二支撑件20的形状可以相同或不同。
折叠件30的位置与折叠屏500的可折叠部位510的位置相对应，同时折叠件30的位置与转轴机构200的位置相对应，折叠件30即位于可折叠部位510与转轴机构200之间，弹性体31也即位于可折叠部位510与转轴机构200之间。折叠件30能够随可折叠部位510的弯折或展开而同步弯折或展开，可以起到支撑可折叠部位510的作用。折叠件30可以连接于第一支撑件10和第二支撑件20，当然也可以与第一支撑件10和第二支撑件20中的至少一者不直接相连(例如存在间隙)。
弹性体31是指具有弹性的结构体，能够发生弹性形变。弹性体31可以包括软性材料，以具有柔性，利于折叠件30发生弯折形变。例如，弹性体31可以是包括具有弹性的聚合物的结构体，其中具有弹性的聚合物可以是橡胶、硅胶、软PVC(Polyvinyl chloride，聚氯乙烯)、TPE(Thermoplastic Elastomer，热塑性弹性体)、TPU(Thermoplastic Urethane，热塑性聚氨酯弹性体)、TPR(Thermo-Plastic-Rubber material，热塑性橡胶)、TPV(Thermoplastic Vulcanizate，热塑性硫化橡胶)等，但不限于此。弹性体31可以呈多种形状的结构，例如可以是相连的一体式结构，也可以是包括多个子弹性体的离散结构。
请参阅图6，在折叠组件100处于展开态时，折叠组件100大致呈平整状，第一支撑件10与第二支撑件20大致处于同一平面，即第一支撑件10与第二支撑件20之间的夹角大致为180°。应理解，在折叠组件100处于展开态时，并非限定第一支撑件10与第二支撑件20之间的夹角为绝对的180°；第一支撑件10与第二支撑件20之间的夹角也可以大于或小于180°，但接近于180°，例如夹角的范围可以为165°至190°(例如170°、173°、175°、182°、185°等，但不限于此)。
请参阅图7，在折叠组件100处于折叠态时，可折叠部位510弯折，以使第一支撑件10与第二支撑件20相对设置。在一些情况下，第一支撑件10与第二支撑件20可以大致平行，即第一支撑件10与第二支撑件20之间的夹角大致为0°。应理解，在折叠组件100处于折叠态时，并非限定第一支撑件10与第二支撑件20绝对平行，第一支撑件10与第二支撑件20之间的夹角也可以大于0°，但接近于0°，例如夹角的范围可以为0°至20°(例如1°、2°、3°、5°、10°、12°、15°、18°、20°等，但不限于此)。
由以上可知，本申请实施例提供的折叠组件100，第一支撑件10、第二支撑件20以及折叠件30能够支撑折叠屏500，以利于提高折叠屏500的形态的稳定性；折叠件30能够支撑折叠屏500的可折叠部位510，由于折叠件30包括弹性体31，在折叠屏500的可折叠部位510受到外力作用时(例如终端设备1000受到撞击或摔落，导致可折叠部位510及折叠件30与转轴机构200发生相互碰撞)，能够通过弹性体31缓冲外力，以减小折叠屏500的可折叠部位510受损的可能性。
在一些实施例中，弹性体31的弹性模量小于第一支撑件10和第二支撑件20的弹性模量，也即弹性体31的刚度小于第一支撑件10和第二支撑件20的刚度，以利于第一支撑件10和第二支撑件20具有一定的刚度以便支撑折叠屏500的除可折叠部位510以外的部位，使得该除可折叠部位510以外的部位能更稳定地处于平整状，进而利于显示；而弹性体31则可具有一定的柔性，以利于缓冲外力。其中，弹性模量可以采用杨氏模量表征。
在一些实施例中，请参阅图6和图7，折叠件30还包括多个第一连接条32。在折叠组件100处于展开态时，定义第一支撑件10朝向第二支撑件20的方向为第一方向a，多个第一连接条32沿第一方向a依次设置，第一连接条32的长度方向L1垂直于第一方向a。弹性体31连接于至少一个第一连接条32；即，弹性体31可以同时连接于所有的第一连接条32，也可以仅连接于其中一个或多个第一连接条32，且与其余的一个或多个第一连接条32不连接。弹性体31的弹性模量小于第一连接条32的弹性模量，也即弹性体31的刚度小于第一连接条32的刚度。
第一连接条32为长条状结构，其长度远大于其宽度和高度。第一连接条32可以是形状规整的矩形条，也可以是形状非规整的长条状结构。在折叠组件100处于展开态时，第一连接条32的厚度方向H1即大致垂直于第一方向a，第一连接条32的厚度方向H1即第一支撑件10的厚度方向H1和第二支撑件20的厚度方向H1；在终端设备1000中，第一支撑件10的厚度方向H1也即折叠屏500的厚度方向；第一连接条32的宽度方向S1即大致平行于第一方向a。第一连接条32的长度方向L1、第一连接条32的厚度方向H1、第一连接条32的宽度方向S1两两相互垂直。可以理解，“依次设置”并非限定为均匀排列，各第一连接条32可以沿第一方向a均匀布置，也可以不均匀布置。
在折叠组件100由展开态转动至折叠态的过程中，折叠件30逐渐弯折，各第一连接条32则可以逐渐聚拢。在折叠组件100由折叠状态转动至展开态的过程中，折叠件30逐渐展平，各第一连接条32则可以逐渐展开。
如此，多个第一连接条32的设置，不仅利于折叠件30的弯折形变，而且因其弹 性模量大于弹性体31的弹性模量，能够提高与弹性体31结合形成的整体的刚度，进而提高对可折叠部位510的支撑作用和防护作用，利于提高可折叠部位510处于弯折形态或平整形态时的稳定性，也即利于可折叠部位510更好地维持在弯折形态或平整形态。

如此设置，第一填充部3111、第二填充部3112和第三填充部3113的填充，不仅可以提高弹性体31、第一连接条32、第一支撑件10及第二支撑件20相结合的结构可靠性，而且可以对相邻两个第一连接条32之间的相对移动、第一连接条32与第一支撑件10之间的相对移动、第一连接条32与第二支撑件20之间的相对移动进行限位和缓冲，有效减小相邻两个第一连接条32之间、第一连接条32与第一支撑件10之间、第一连接条32与第二支撑件20之间发生相对移动或错位而导致可折叠部位510的形态不稳定的可能性，以利于提高可折叠部位510处于弯折形态时的稳定性，同时可使弹性体31分布相对较广，利于提高缓冲外力的效果。

可选地，请参阅图6和图7，第一填充部3111、第二填充部3112和第三填充部3113均可以连接于基部312，以利于通过基部312将第一填充部3111、第二填充部3112和第三填充部3113连接为一体，可减小第一填充部3111、第二填充部3112和第三填充部3113发生脱落的可能性，提高弹性体31的整体可靠性，以及提高弹性体31与第一连接条32连接的牢靠性。同时，第一填充部3111、第二填充部3112、第三填充部3113和基部312均能够发生弹性形变，利于提高缓冲外力的效果。
当然，在其他一些实施例中，第一填充部3111、第二填充部3112和第三填充部3113中至少一者也可以不与基部312连接。
可选地，请参阅图6和图7，基部312可以为层状结构或片状结构，以利于具有较大的面积，可分布较广，更利于提高弹性体31缓冲外力的效果。
当然，在其他一些实施例中，基部312也可以包括多个间隔设置的子基部，子基部可以为片状结构、板状结构、条状结构、杆状结构等，但不限于此。
可选地，请参阅图6和图9，在折叠组件100处于展开态时，基部312背向第一连接条32的表面可以与第一支撑件10和第二支撑件20的下表面大致齐平，不易干涉终端设备1000的其他部件(例如转轴机构200)。
当然，在其他一些实施例中，在折叠组件100处于展开态时，基部312背向第一连接条32的表面与第一支撑件10及第二支撑件20的下表面也可以不齐平，即基部312背向第一连接条32的表面可以高于或低于第一支撑件10和第二支撑件20的下表面。
需要说明的是，在其他一些实施例中，弹性体31可以不设置基部312，而设置第一填充部3111、第二填充部3112和第三填充部3113中的至少一者。图10即示例性地示出了不设置基部312的折叠组件100在展开态下的结构示意图。
可选地，在一些实施例中，请参阅图11，图11示出了本申请另一些实施例提供的折叠组件100在展开态下的立体结构示意图。折叠件30还包括多个第二连接条33。在折叠组件100处于展开态时，多个第二连接条33沿第一方向a依次设置，第二连接条33的长度方向垂直于第一方向a。各第一连接条32形成第一连接条组320，各第二连接条33形成第二连接条组330。在折叠组件100处于展开态时，第一连接条组320和第二连接条组330沿第一支撑件10的厚度方向H1间隔设置。弹性体31连接于至少一个第二连接条33；即，弹性体31可以同时连接于所有的第二连接条33，也可以仅连接于其中一个或多个第二连接条33，且与其余的一个或多个第二连接条33不连接。弹性体31的弹性模量小于第二连接条33的弹性模量，也即弹性体31的刚度小于第二连接条33的刚度。
第二连接条33为长条状结构，其长度远大于其宽度和高度。第二连接条33可以是形状规整的矩形条，也可以是形状非规整的长条状结构。在折叠组件100处于展开态时，第二连接条33的长度方向即大致平行于第一连接条32的长度方向L1，第二连接条33的厚度方向即大致平行于第一连接条32的厚度方向，第二连接条33的宽度方向即大致平行于第一连接条32的宽度方向。第二连接条33的长度方向、第二连接条33的厚度方向、第二连接条33的宽度方向两两相互垂直。可以理解，第二连接条33的形状和结构可以与第一连接条32的形状和结构相同或不同。各第二连接条33可以 沿第一方向a均匀布置，也可以不均匀布置。
在折叠组件100由展开态转动至折叠态的过程中，折叠件30逐渐弯折，各第一连接条32可以逐渐聚拢，各第二连接条33也可以逐渐聚拢。在折叠组件100由折叠状态转动至展开状态的过程中，折叠件30逐渐展平，各第一连接条32可以逐渐展开，各第二连接条33也可以逐渐展开。
如此设置，由于在折叠组件100处于展开态时，第一连接条组320和第二连接条组330沿第一支撑件10的厚度方向H1间隔设置，即相当于设置两排间隔设置的连接条组，且由于第二连接条33的弹性模量大于弹性体31的弹性模量，能够进一步提高折叠件30的刚度和结构可靠性，不仅可提高可折叠部位510处于弯折形态或平整形态时的稳定性，而且也能够提高折叠件30对可折叠部位510的防护效果，降低可折叠部位510与转轴机构200发生碰撞而导致失效的可能性。
可选地，请参阅图11，第二连接条33与第一连接条32相对设置。在折叠组件100处于展开态时，第二连接条33与第一连接条32沿第一支撑件10的厚度方向H1相对设置。
如此设置，便于第二连接条33与第一连接条32的成型或安装排布，而且，相邻两个第二连接条33之间形成的空间与相邻两个第一连接条32之间形成的空间也相对设置，利于折叠件30弯折。
当然，第二连接条33与第一连接条32不限于沿第一支撑件10的厚度方向H1相对设置。在其他一些实施例中，请参阅图12，图12示出了本申请另一些实施例提供的折叠组件100在展开态下的立体结构示意图。在折叠组件100处于展开态时，沿第一支撑件10的厚度方向H1的投影，至少一个第二连接条33位于相邻两个第一连接条32之间，也可以理解为第二连接条33与第一连接条32错位设置。这样，利于提高折叠件30的整体结构可靠性，进而利于提高折叠件30对可折叠部位510的支撑效果和防护效果。
可选地，请参阅图11和图12，弹性体31还包括基部312，基部312位于第一连接条组320与第二连接条组330之间。
如此设置，第一连接条组320与第二连接条组330之间即被基部312间隔开，在折叠屏500与转轴机构200之间发生相互碰撞时，第一连接条组320与第二连接条组330均可以将力传递至基部312，以通过基部312进行缓冲，避免第一连接条组320与第二连接条组330直接相撞，可提高折叠件30缓冲外力的效果。另外，基部312可以同时与第一连接条组320及第二连接条组330相连接，利于提高折叠件30的结构可靠性。
可选地，请参阅图11和图12，基部312可以连接于各第一连接条32和各第二连接条33，利于提高弹性体31缓冲外力的效果。当然，基部312也可以与至少一个第一连接条32和/或至少一个第二连接条33不连接。
可选地，请参阅图11和图12，相邻两个第二连接条33之间形成有第二空间，弹性体31还包括第四填充部3131，第四填充部3131连接于基部312，并设置于至少一个第二空间内。弹性体31还包括第五填充部3132，第五填充部3132连接于基部312，并设置于第一支撑件10与第二连接条33之间。弹性体31还包括第六填充部3133， 第六填充部3133连接于基部312，并设置于第二支撑件20与第二连接条33之间。
可以理解，第四填充部3131、第五填充部3132及第六填充部3133均为弹性体31的一部分，均能够发生弹性形变。
如此设置，第四填充部3131、第五填充部3132及第六填充部3133的填充，不仅可以提高弹性体31、第二连接条33、第一支撑件10及第二支撑件20相结合的结构可靠性，而且可以对相邻两个第二连接条33之间的相对移动、第二连接条33与第一支撑件10之间的相对移动、第二连接条33与第二支撑件20之间的相对移动进行限位和缓冲，有效减小相邻两个第二连接条33之间、第一连接条32与第一支撑件10之间、第一连接条32与第二支撑件20之间发生相对移动的可能性，以利于提高可折叠部位510处于弯折形态时的稳定性，同时可使弹性体31分布相对较广，利于提高缓冲外力的效果。
另外，通过基部312将第四填充部3131、第五填充部3132及第六填充部3133连接为一体，可减小第四填充部3131、第五填充部3132及第六填充部3133发生脱落的可能性，提高弹性体31的整体可靠性，以及弹性体31与第二连接条33连接的牢靠性；而且，通过基部312与第四填充部3131、第五填充部3132、第六填充部3133配合，弹性体31具有更优异的缓冲外力效果。
可选地，第四填充部3131可以完全填充第二空间，利于提高限位和缓冲的效果；当然，第四填充部3131也可以仅填充第二空间的一部分，并空出另一部分不填充。同样地，第五填充部3132可以完全填充第一支撑件10与第二连接条33之间的空间，也可以仅填充第一支撑件10与第二连接条33之间的一部分空间，并空出另一部分空间不填充。第六填充部3133可以完全填充第二支撑件20与第二连接条33之间的空间，也可以仅填充第二支撑件20与第二连接条33之间的一部分空间，并空出另一部分空间不填充。
需要说明的是，在其他一些实施例中，也可以不设置第四填充部3131、第五填充部3132及第六填充部3133中的至少一者。图13即示例性地示出了第四填充部3131、第五填充部3132及第六填充部3133均不设置的折叠组件100在展开态下的立体结构示意图。
可选地，在一些实施例中，请参阅图11，在折叠组件100处于展开态时，各第一连接条32沿第一方向a均匀布置，即任意相邻两个第一连接条32之间的距离大致相同，各第二连接条33沿第一方向a均匀布置，任意相邻两个第二连接条33之间的距离大致相同。
如此设置，折叠件30整体结构强度较为均匀，可提高对可折叠部位510的支撑效果和防护效果，利于提高可折叠部位510处于弯折形态和平整形态时的稳定性。
可选地，在另一些实施例中，请参阅图14，图14示出了本申请另一些实施例提供的折叠组件100在展开态下的立体结构示意图。折叠件30包括第一区域301、第二区域302以及第三区域303，第一区域301位于第一支撑件10的一侧，第二区域302位于第二支撑件20的一侧，第三区域303位于第一区域301与第二区域302之间。第一区域301和第二区域302均设置有至少一个第一连接条32，第三区域303不设置第一连接条32。第一区域301和第二区域302均设置有至少一个第二连接条33，第三区域 303不设置第二连接条33。
定义可折叠部位510靠近第一支撑件10的一侧部为第一弯折部位5101，可折叠部位510靠近第二支撑件20的另一侧部为第二弯折部位5102，例如图5所示。第一弯折部位5101和第二弯折部位5102即为可折叠部位510与折叠屏500的其他部位之间的过渡部位，在可折叠部位510受到外力作用时，第一弯折部位5101和第二弯折部位5102通常最易受损，尤其是在折叠屏500处于折叠态时，可折叠部位510呈弯折形态，在受外力作用时，第一弯折部位5101和第二弯折部位5102通常为应力集中的部位，最易受损，特别是在可折叠部位510的弯折形态呈水滴形时更是如此。第一区域301的位置即大致与第一弯折部位5101的位置相对应，第二区域302的位置即大致与第二弯折部位5102的位置相对应。
如此设置，通过在第一区域301和第二区域302设置至少一个第一连接条32和至少一个第二连接条33，而第三区域303不设置第一连接条32和第二连接条33，使得折叠件30靠近第一支撑件10的部分和靠近第二支撑件20的部分的强度大于中间部分的强度，能够对可折叠部位510的两侧部进行有效的支撑和防护，减小可折叠部位510最易受损的部位发生损坏的可能性，提高折叠屏500的安全性，而第三区域303因不设置第一连接条32和第二连接条33，可节省材料，减小重量。
当然，在其他一些实施例中，当折叠件30不设置第二连接条33时，可以是第一区域301和第二区域302均设置有至少一个第一连接条32，第三区域303不设置第一连接条32，图15即示例性地示出了不设置第二连接条33的折叠组件100在展开态下的立体结构示意图。
在一些实施例中，请参阅图6和图8，第一支撑件10包括第一侧面11，在折叠组件100处于展开态时，第一侧面11朝向第二支撑件20。第一侧面11上开设有第一槽1101；弹性体31包括第一连接部3141，第一连接部3141设置于第一槽1101内。可以理解，第一连接部3141为弹性体31的一部分，也能够发生弹性形变。
如此设置，由于弹性体31通过第一连接部3141连接于第一支撑件10的第一槽1101内，可提高弹性体31与第一支撑件10相连接的牢固性，进而提高折叠件30与第一支撑件10相连接的可靠性。
可选地，请参阅图6和图8，第一连接部3141可以连接于基部312，此时也可以视为第一连接部3141由基部312朝向第一支撑件10延伸而形成。第一连接部3141与基部312可以为一体成型的一体式结构，结构可靠性高。
可选地，请参阅图6和图8，第一连接部3141的端部与第一槽1101的内壁之间形成有第一空隙101。应理解，第一空隙101的宽度或尺寸可以根据需要进行设置；在第一空隙101的宽度较小时，肉眼看起来可能不明显，但第一连接部3141的端部与第一槽1101的内壁之间只要不是完全贴合，均应认为第一连接部3141的端部与第一槽1101的内壁之间形成有第一空隙101。
如此设置，当折叠组件100在折叠态和展开态之间切换时，第一空隙101可以提供避让空间，能够容纳第一连接部3141发生形变时的挤压形变量，可减小因挤压形变量而导致第一连接部3141与第一支撑件10发生脱离的可能性，以及减小因挤压形变量导致弹性体31发生拱起的可能性，进而提高弹性体31与第一支撑件10相连接的稳 定性。同时，由于第一连接部3141和第一支撑件10为不同材料，受外界环境影响时(例如受温度影响)，第一连接部3141的膨胀量与第一支撑件10的膨胀量不同，第一空隙101则可以容纳第一连接部3141产生的膨胀量，可减小因膨胀量导致第一连接部3141与第一支撑件10发生脱离的可能性，以及减小因膨胀量导致弹性体31发生拱起现象的可能性。
可选地，在一些实施例中，请参阅图6和图8，第二支撑件20包括第二侧面21，在折叠组件100处于展开态时，第二侧面21朝向第一支撑件10，即第二侧面21与第一侧面11相对设置。第二侧面21上开设有第二槽2101；弹性体31还包括第二连接部3142，第二连接部3142设置于第二槽2101内。可以理解，第二连接部3142为弹性体31的一部分，也能够发生弹性形变。
如此设置，由于弹性体31通过第二连接部3142连接于第二支撑件20的第二槽2101内，可提高弹性体31与第二支撑件20相连接的牢固性，进而提高折叠件30与第二支撑件20相连接的可靠性。
可选地，请参阅图6和图8，第二连接部3142可以连接于基部312，此时也可以视为第二连接部3142由基部312朝向第二支撑件20延伸而形成。第二连接部3142与基部312可以为一体成型的一体式结构，结构可靠性高。
可选地，请参阅图6和图8，第二连接部3142的端部与第二槽2101的内壁之间形成有第二空隙102。应理解，第二空隙102的宽度或尺寸可以根据需要进行设置；在第二空隙102的宽度较小时，肉眼看起来可能不明显，但第二连接部3142的端部与第二槽2101的内壁之间只要不是完全贴合，均应认为第二连接部3142的端部与第二槽2101的内壁之间形成有第二空隙102。
如此设置，当折叠组件100在折叠态和展开态之间切换时，不仅第一空隙101可以提供避让空间，能够容纳第一连接部3141发生形变时的挤压形变量以及第一连接部3141受外界环境影响而产生的膨胀量，而且第二槽2101也能够提供避让空间，能够容纳第二连接部3142发生形变时的挤压形变量以及第二连接部3142受外界环境影响产生的膨胀量，可减小第二连接部3142与第二支撑件20发生脱离的可能性，可进一步减小因挤压形变量或膨胀量导致弹性体31发生拱起现象的可能性，从而提高折叠件30的稳定性。
弹性体31与第一连接条32之间的配合关系或连接方式具有多种，下面将示例性地进行介绍。
可选地，在一些实施例中，请参阅图6，弹性体31为间隔垫；即，弹性体31为与第一连接条32分体设置的垫层结构，也即将已经成型后的弹性体31与第一连接条32相连接。
可选地，为间隔垫的弹性体31可以直接设置于第一连接条32上，也可以通过粘胶等与第一连接条32相连接。
可选地，在另一些实施例中，请参阅图8，弹性体31为涂设于第一连接条32上的涂层；即，将未成型的涂料(呈流体状体，例如可以是多种材质的胶)涂设于第一连接条32上，固化后即可形成为涂层的弹性体31。这样，便于弹性体31的加工成型，无需另外采用粘胶进行粘接。

可以理解，第一凸伸部3151可以是各种形状规则或不规则的凸出结构，例如条状结构、柱状结构、鼓包结构、锥形结构、球形结构等，但不限于此。
如此设置，在折叠屏500受到外力作用时，例如折叠屏500与转轴机构200之间发生相互碰撞时，由于第一凸伸部3151凸出于第一面12，可首先受力形变，即可使弹性体31首先受力以缓冲外力，利于提高缓冲外力的效果，第一凸伸部3151即可起到弹簧的作用。

如此设置，在折叠屏500受到外力作用时，例如折叠屏500与转轴机构200之间发生相互碰撞时，第一凸伸部3151首先受力且可以发生形变以抵抗外力，第一间隙3001则可以容纳第一凸伸部3151产生的形变量，以利于第一凸伸部3151能够充分形变以抵抗外力，可有效提高缓冲外力的作用；而且多个间隔设置的第一凸伸部3151相比于面积较大的板状结构而言，受力更易发生形变，可提高缓冲效果。
可选地，请参阅图16和图18，第一凸伸部3151为凸条结构；在折叠组件100处于展开态时，第一支撑件10朝向第二支撑件20的方向为第一方向a，多个第一凸伸部3151沿第一方向a依次设置，第一凸伸部3151的长度方向垂直于第一方向a。

示例性地，请参阅图16和图17，在终端设备1000中，第一凸伸部3151朝向折叠屏500凸伸，在折叠组件100由展开态转动至折叠态的过程中，折叠件30逐渐弯折，各第一凸伸部3151可以逐渐聚拢。在折叠组件100由折叠状态转动至展开状态的过程中，折叠件30逐渐展平，各第一凸伸部3151可以逐渐展开。

可选地，在另一些实施例中，请参阅图20和图21，图20示出了本申请另一些实施例提供的折叠组件100在展开态下的立体结构示意图，图21示意了图20所示折叠组件100与折叠屏500相配合并处于折叠态时的结构示意图。折叠件30包括第一区域301、第二区域302以及第三区域303，第一区域301位于第一支撑件10的一侧，第二区域302位于第二支撑件20的一侧，第三区域303位于第一区域301与第二区域302之间。第一区域301和第二区域302均设置有至少一个第一凸伸部3151，第三区域303不设置第一凸伸部3151。
如此设置，在可折叠部位510处于折叠态时，折叠件30靠近第一支撑件10的部分和靠近第二支撑件20的部分均能够通过第一凸伸部3151缓冲外力，也即可折叠部位510的两侧部(第一弯折部位5101和第二弯折部位5102)均能够受到第一凸伸部3151的防护作用，可减小可折叠部位510最易受损的部位发生损坏的可能性，提高折叠屏500的安全性。尤其适用于可折叠部位510的弯折形态呈水滴形的情况，因为在可折叠部位510的弯折形态呈水滴形时，第一弯折部位5101的外侧和第二弯折部位5102的外侧均能够形成凹设空间501，利于避让第一凸伸部3151，提高可折叠部位510处于弯折形态的稳定性。
同时，因第三区域303不设置第一凸伸部3151，可形成避位空间，在第一面12朝向折叠屏500时，避位空间可避让呈弯折形态的可折叠部位510的冗余量，利于提高可折叠部位510处于弯折形态时的稳定性，以及可使可折叠部位510处于弯折形态时表面更平滑顺畅(不易因处于弯折形态时与折叠件30相抵而产生褶皱或隆起)，在第一面12朝向转轴机构200时，避位空间可避让转轴机构200；而且，第三区域303因不设置第一凸伸部3151，利于节省材料，减小重量。

可以理解，在第一凸伸部3151的数量为多个时，凹槽401的数量可以与第一凸伸 部3151的数量相同，以使第一凸伸部3151与凹槽401一一对应设置。支撑膜40为薄膜结构，可以是硬质材质的支撑膜，例如可以包括金属材料(例如不锈钢等)、合金等，但不限于此；也可以是软性材质的支撑膜，例如可以包括橡胶、硅胶、软PVC、TPE、TPU、TPR、TPV等，但不限于此。
如此设置，支撑膜40的设置，可以对折叠屏500起到支撑和防护的效果，可提高折叠屏500受外力作用时的可靠性，进一步降低可折叠部位510受外力作用时受损的可能性。同时，支撑膜40上开设的凹槽401可对伸入的第一凸伸部3151进行限位，以减小第一凸伸部3151发生偏移的可能性，可限制第一凸伸部3151与支撑膜40之间发生较大的相对移动，利于提高折叠件30在弯折或展平过程中的稳定性以及受外力作用时的稳定性，以及折叠件30与支撑膜40之间配合的稳定性，进而可提高对可折叠部位510的支撑和防护效果，利于可折叠部位510更为稳定地维持弯折形态或平整形态。
示例性地，请参阅图23，图23示意了采用图22所示折叠组件100的终端设备1000的局部结构示意图。在终端设备1000中，第一面12朝向转轴机构200，第一凸伸部3151即朝向转轴机构200凸伸，支撑膜40即位于折叠件30与转轴机构200之间。支撑膜40可以固定于转轴机构200、第一壳体300和第二壳体400中的至少一者，支撑膜40与第一支撑件10之间、支撑膜40与第二支撑件20之间可以具有间隙。终端设备1000在折叠态与展开态之间切换时，支撑膜40上开设的凹槽401可对第一凸伸部3151进行限位，进而可限制折叠件30与支撑膜40之间、折叠件30与折叠屏500之间发生较大的相对移动，利于可折叠部位510更为稳定地维持弯折形态或平整形态。
示例性地，在终端设备1000中，第一面12朝向转轴机构200，第一凸伸部3151即朝向转轴机构200凸伸，支撑膜40即位于折叠件30与转轴机构200之间。支撑膜40可以固定于第一支撑件10和第二支撑件20中的至少一者，支撑膜40与转轴机构200之间可以具有间隙。终端设备1000在折叠态与展开态之间切换时，支撑膜40上开设的凹槽401可对第一凸伸部3151进行限位，进而可限制折叠件30与支撑膜40之间发生较大的相对移动，可提高折叠件30与支撑膜40之间配合的稳定性，进而利于可折叠部位510更为稳定地维持弯折形态或平整形态。
示例性地，在终端设备1000中，第一面12朝向折叠屏500，第一凸伸部3151即朝向折叠屏500凸伸，支撑膜40即位于折叠件30与折叠屏500之间。支撑膜40可以固定于第一支撑件10和第二支撑件20中的至少一者，或者固定于折叠屏500。终端设备1000在折叠态与展开态之间切换时，支撑膜40上开设的凹槽401可对第一凸伸部3151进行限位，进而可限制折叠件30与支撑膜40之间、折叠件30与折叠屏500之间发生较大的相对移动，利于可折叠部位510更为稳定地维持弯折形态或平整形态。
