在本申请中，第一壳体与第二壳体能够相对展开至打开状态或者相对折叠至闭合状态，对应于电子设备具有打开状态和闭合状态，折叠装置及折叠组件亦具有对应的打开状态和闭合状态。其中，折叠组件的第一固定架通过第一转动臂转动连接中轴，第二固定架通过第二转动臂转动连接中轴，第一固定架和第二固定架能够相对中轴转动，以相对展开至打开状态或相对折叠至闭合状态。
在折叠组件中，第一转动臂与第一固定架之间通过虚拟轴结构实现转动连接，第一转动臂的第二端于第一固定架之中设计有一定的间隙，以实现顺畅的转动运动。第一壳体与第二壳体处于打开状态时，第一弹性件处于压缩状态，第一弹性件的两端分别接触第一固定架和第一转动臂的第二端，第一弹性件产生的弹性力使得第一固定架和第一转动臂向远离彼此的方向撑开，以吸收第一固定架与第一转动臂之间的间隙，使得第一固定架与第一转动臂在打开状态中能够运动到位。
第二转动臂与第二固定架之间通过虚拟轴结构实现转动连接，第二转动臂的第二端于第二固定架之中设计有一定的间隙，以实现顺畅的转动运动。第一壳体与第二壳体处于打开状态时，第二弹性件也处于压缩状态，第二弹性件的两端分别接触第二固定架和第二转动臂的第二端，第二弹性件产生的弹性力使得第二固定架和第二转动臂向远离彼此的方向撑开，以吸收第二固定架与第二转动臂之间的间隙，使得第二固定架和第二转动臂在打开状态中能够运动到位。
在本申请中，由于第一固定架与第一转动臂之间的间隙被吸收、第二固定架与第二转动臂之间的间隙被吸收，第一固定架和第二固定架向远离中轴的方向展开到位，因此折叠组件可以更好地撑平柔性显示屏的折弯部，避免柔性显示屏由于长期的弯折而导致中间拱起的问题，以提高柔性显示屏的平整度和可靠性。

在本实现方式中，第一转动臂与中轴之间通过虚拟轴结构实现转动连接，第二转动臂与中轴之间通过虚拟轴结构实现转动连接，有利于降低转动臂与中轴的转动连接结构的设计难度，且能够降低折叠组件的整体厚度，有利于折叠组件的轻薄化。

此外，折叠组件能够实现在打开状态向闭合状态变化的过程中的固定架内拉运动、和折叠组件在闭合状态向打开状态变化的过程中的固定架外推运动，因此折叠组件的长度尺寸在运动过程中能够保持一致或较为接近，从而能够更好地支撑柔性显示屏的折弯部，降低拉扯或挤压柔性显示屏的风险，提高柔性显示屏和电子设备的可靠性和使用寿命。其中，折叠组件的长度尺寸是指自第一固定架的背向中轴的端部、经中轴、延伸至第二固定架的背向中轴的端部的尺寸，该尺寸为动态尺寸，随折叠组件的运动发生变化。
同时，由于第一转动臂与第一固定架之间通过第一弹性件撑开，第二转动臂与第二固定架之间通过第二弹性件撑开，第一弹性件和第二弹性件在外力作用下可以发生形变，因此在折叠组件的运动过程中，第一转动臂与第一固定架之间的运动间隙和第二转动臂与第二固定架之间的运动间隙能够使第一固定架与第二固定架之间的相对运动更为顺畅，且第一弹性件和第二弹性件的弹性力使得第一固定架和第二固定架保持撑开状态，以更好地支撑柔性显示屏的折弯部，以确保柔性显示屏的可靠性。

如图1所示，第一壳体1与第二壳体2能够相对展开至打开状态，以使电子设备100处于打开状态。示例性的，第一壳体1与第二壳体2处于打开状态时，两者可以大致呈180°(也允许存在少许偏差，例如165°、177°或者185°)。如图2所示，第一壳体1与第二壳体2能够相对转动(展开或折叠)至中间状态，以使电子设备100处于中间状态。如图3所示，第一壳体1与第二壳体2能够相对折叠至闭合状态，以使电子设备100处于闭合状态。示例性的，第一壳体1与第二壳体2处于闭合状态时，两者能够完全合拢至相互平行(也允许存在少许偏差)。其中，图2所示中间状态，可以为打开状态与闭合状态之间的任意状态。故而，电子设备100可以通过折叠组件3的运动，在打开状态与闭合状态之间相互切换。

在本实施例中，柔性显示屏20能够随折叠装置10展开或折叠。当电子设备100处于打开状态时，柔性显示屏20处于展平形态，能够全屏进行显示，使得电子设备100具有较大的 显示面积，以提高用户的观看体验。当电子设备100处于闭合状态时，电子设备100的平面尺寸较小(具有较小的宽度尺寸)，便于用户携带和收纳。
可以理解的是，本实施例是以“电子设备100的转动中心平行于电子设备100的宽度方向”为例进行说明的，此时，电子设备100能够实现左右转动，电子设备100的展开或折叠影响到电子设备100的宽度尺寸。在其他一些实施例中，电子设备100的转动中心也可以平行于电子设备100的长度方向，此时，电子设备100能够实现上下转动，电子设备100的展开或折叠影响到电子设备100的长度尺寸。

一些实施例中，第一转动臂323的第一端323a转动连接中轴31，第一转动臂323的第二端323b转动连接第一固定架321。第一传动臂324的转动端324a转动连接中轴31，第一传动臂324的滑动端324b滑动连接第一固定架321。第二转动臂325的第一端325a转动连接中轴31，第二转动臂325的第二端325b转动连接第二固定架322。第二传动臂326的转动端326a转动连接中轴31，第二传动臂326的滑动端326b滑动连接第二固定架322。
在本实施例中，第一固定架321通过第一转动臂323转动连接中轴31，第二固定架322通过第二转动臂325转动连接中轴31，第一固定架321和第二固定架322能够相对中轴31转动，以相对展开至打开状态或相对折叠至闭合状态。如图12至图15所示，折叠组件3处于打开状态时，第一固定架321和第二固定架322分别位于中轴31的两侧，两者可以呈展平形态。如图16和图17所示，折叠组件3处于闭合状态时，第一固定架321和第二固定架322位于中轴31的同一侧，两者可以呈折叠形态。
其中，第一传动臂324与中轴31转动连接、与第一固定架321滑动连接，形成了连杆滑块结构，第一转动臂323与中轴31转动连接、与第一固定架321转动连接，形成了连杆结构；第二传动臂326与中轴31转动连接、与第二固定架322滑动连接，形成了连杆滑块结构，第二转动臂325与中轴31转动连接、与第二固定架322转动连接，形成了连杆结构。折叠组件3通过连杆滑块结构和连杆结构实现固定架(321、322)与中轴31之间的连接，其组成部分数量少，配合关系及配合位置简单，组成部件易制作和组装，有利于实现量产。并且，由于中轴31通过第一传动臂324和第一转动臂323联动第一固定架321、且通过第二传动臂326和第二转动臂325联动第二固定架322，因此折叠组件3具有较佳的机构抗拉能力和机构抗挤压能力。
示例性的，如图12至图15所示，折叠组件3处于打开状态时，第一固定架321和第二固定架322远离中轴31、形成间距，如图16和图17所示，第一固定架321和第二固定架322靠近中轴31，第一固定架321和第二固定架322的部分结构嵌入中轴31。因此，折叠组件3通过第一传动臂324和第一转动臂323共同控制第一固定架321的运动轨迹、通过第二传动臂326和第二转动臂325共同控制第二固定架322的运动轨迹，能够实现在打开状态向闭合状态变化的过程中的固定架内拉运动、和折叠组件3在闭合状态向打开状态变化的过程中的固定架外推运动，因此折叠组件3的长度尺寸在运动过程中能够保持一致或较为接近，从而能够更好地支撑柔性显示屏20的折弯部202(可以参阅图1)，降低拉扯或挤压柔性显示屏20的风险，提高柔性显示屏20和电子设备100的可靠性和使用寿命。其中，折叠组件3的长度尺寸是指自第一固定架321的背向中轴31的端部、经中轴31、延伸至第二固定架322的背向中轴31的端部的尺寸，该尺寸为动态尺寸，随折叠组件3的运动发生变化。
在本申请中，由于第一固定架321固定连接第一壳体1，第二固定架322固定连接第二壳体2，因此折叠装置10能够通过第一传动臂324和第一转动臂323共同控制第一固定架321和第一壳体1的运动轨迹、通过第二传动臂326和第二转动臂325共同控制第二固定架322和第二壳体2的运动轨迹，从而能够在第一壳体1与第二壳体2相对折叠的过程中，使第一固定架321带动第一壳体1向靠近中轴31的方向移动、第二固定架322带动第二壳体2向靠近中轴31的方向移动，在第一壳体1与第二壳体2相对展开的过程中，使第一固定架321带动第一壳体1向远离中轴31的方向移动、第二固定架322带动第二壳体2向远离中轴31的 方向移动。也即，折叠装置10能够实现在展平状态向闭合状态变化的过程中的壳体内拉运动、和在闭合状态向展平状态变化的过程中的壳体外推运动，使得折叠装置10在展开或折叠的过程中，能够实现以柔性显示屏20处于中性面或者靠近中性面的变形运动，从而降低拉扯或挤压柔性显示屏20的风险，以保护柔性显示屏20，提高柔性显示屏20的可靠性，使得柔性显示屏20和电子设备100具有较长的使用寿命。
可以理解的是，在其他一些实施例中，折叠组件3也可以采用连杆结构和其他连接结构的配合，以实现第一固定架321和第二固定架322相对中轴31转动的运动过程，本申请实施例对此不作严格限定。

在本实施例中，第一转动臂323与中轴31之间通过虚拟轴结构实现转动连接，第二转动臂325与中轴31之间通过虚拟轴结构实现转动连接，有利于降低转动臂与中轴31的转动连接结构的设计难度，且能够降低折叠组件3的整体厚度，有利于折叠组件3的轻薄化。
此外，第一转动臂323通过虚拟轴结构转动连接第一固定架321，有利于降低第一固定架321的厚度，第二转动臂325通过虚拟轴结构转动连接第二固定架322，有利于降低第二固定架322的厚度，使得折叠组件3对安装空间的要求较低，折叠组件3与第一壳体1及第二壳体2的组装难度小，并且有利于减薄折叠装置10及电子设备100的整体厚度。
请结合参阅图12、图18以及图19，第一弹性件36安装于第一固定架321，第一弹性件36靠近中轴31的一端接触第一转动臂323的第二端323b，第一弹性件36远离中轴31的一端接触第一固定架321。第二弹性件37安装于第二固定架322，第二弹性件37靠近中轴31的一端接触第二转动臂325的第二端325b，第二弹性件37远离中轴31的一端接触第二固定架322。折叠组件3处于打开状态时，第一固定架321和第二固定架322分别位于中轴31的两侧，第一弹性件36和第二弹性件37处于压缩状态。
在本实施例中，第一转动臂323与第一固定架321之间通过虚拟轴结构实现转动连接，第一转动臂323的第二端323b于第一固定架321之中设计有一定的间隙，以实现顺畅的转动运动。折叠组件3处于打开状态时，第一弹性件36处于压缩状态，第一弹性件36的两端分别接触第一固定架321和第一转动臂323的第二端323b，第一弹性件36产生的弹性力使得第一固定架321和第一转动臂323向远离彼此的方向撑开，以吸收第一固定架321与第一转动臂323之间的间隙，使得第一固定架321与第一转动臂323在打开状态中能够运动到位。第二转动臂325与第二固定架322之间通过虚拟轴结构实现转动连接，第二转动臂325的第二端325b于第二固定架322之中设计有一定的间隙，以实现顺畅的转动运动。折叠组件3处于打开状态时，第二弹性件37也处于压缩状态，第二弹性件37的两端分别接触第二固定架 322和第二转动臂325的第二端325b，第二弹性件37产生的弹性力使得第二固定架322和第二转动臂325向远离彼此的方向撑开，以吸收第二固定架322与第二转动臂325之间的间隙，使得第二固定架322和第二转动臂325在打开状态中能够运动到位。
在本实施例中，由于第一固定架321与第一转动臂323之间的间隙被吸收、第二固定架322与第二转动臂325之间的间隙被吸收，第一固定架321和第二固定架322向远离中轴31的方向展开到位，因此折叠组件3可以更好地撑平柔性显示屏20的折弯部202，避免柔性显示屏20由于长期的弯折而导致中间拱起的问题，以提高柔性显示屏20的平整度和可靠性。
请参阅图20和图21，图20是图18所示结构处于闭合状态时的结构示意图，图21是图19所示结构处于闭合状态时的结构示意图。
一些实施例中，折叠组件3处于闭合状态时，第一固定架321和第二固定架322位于中轴31的同一侧且相对设置，第一弹性件36和第二弹性件37可以处于压缩状态。
在本实施例中，折叠组件3处于闭合状态时，第一弹性件36和第二弹性件37处于压缩状态，第一弹性件36和第二弹性件37产生的弹性力同样可以实现吸收运动间隙的目的，使得柔性显示屏20被折叠装置10撑开，不易产生褶皱或拱起，以具有较高的可靠性。
其中，在折叠组件3的运动过程中，第一弹性件36和第二弹性件37的状态可以发生变化，例如在压缩状态与自然状态之间变化，或者压缩程度变化，本申请对此不作严格限定。第一弹性件36和第二弹性件37在打开状态和闭合状态中的压缩程度可以相同，也可以不同，本申请对此不作严格限定。例如，在其他一些实现方式中，折叠组件3处于闭合状态时，第一弹性件36和第二弹性件37也可以处于自然状态。
同时，由于第一转动臂323与第一固定架321之间通过第一弹性件36撑开，第二转动臂325与第二固定架322之间通过第二弹性件37撑开，第一弹性件36和第二弹性件37在外力作用下可以发生形变，因此在折叠组件3的运动过程中，第一转动臂323与第一固定架321之间的运动间隙和第二转动臂325与第二固定架322之间的运动间隙能够使第一固定架321与第二固定架322之间的相对运动更为顺畅，且第一弹性件36和第二弹性件37的弹性力使得第一固定架321和第二固定架322保持撑开状态，以更好地支撑柔性显示屏20的折弯部202，以确保柔性显示屏20的可靠性。
示例性的，如图18和图20所示，第一弹性件36的第一支架362抵持第一转动臂323，第一弹性件36的第一弹性主体361的两端分别抵持第一支架362和第一固定架321。在本实施例中，第一弹性主体361用于为第一弹性件36提供弹性力，第一支架362与第一转动臂323的连接结构稳定、准确，使得第一弹性件36既可以提供弹性力，其还能与第一转动臂323准确配合，有利于确保折叠组件3的运动可靠性。

其中，第二连通口322c的壁面还可以用于第二抵持块3252进行限位，以避免第二转动臂325脱离第二固定架322，提高了折叠组件3的可靠性。
示例性的，如图19所示，折叠组件3处于打开状态时，第二转动臂325的第二端325b的第二抵持块3252可以接触第二支架372的第二配合块3722的顶面3722a或过渡面3722b；如图21所示，折叠组件3处于闭合状态时，第二转动臂325的第二端325b的第二抵持块3252可以接触第二配合块3722的连接面3722c。
在本实施例中，通过设计第二配合块3722的结构、第二转动臂325在打开状态和闭合状态中与第二配合块3722的配合结构，使得第二弹性主体371在打开状态中处于压缩状态，以提供弹性力。在一些实施例中，同样的，也可以通过第二配合块3722的结构及其与第二转动臂325的配合结构，使得第二弹性主体371在闭合状态中处于压缩状态。
可以理解的是，在其他一些实施例中，第一配合块3622与第一抵持块3232之间的配合结构和/或第二配合块3722与第二抵持块3252之间的配合结构也可以有其他实现方式，本申请实施例对此不作严格限定。在其他一些实施例中，第一转动臂323也可以不设置第一抵持块3232，第一支架362也可以有其他结构，第一转动臂323的第二端323b由弧形臂的端部直接抵持第一支架362；第二转动臂325也可以不设置第二抵持块3252，第二支架372也可以有其他结构，第二转动臂325的第二端325b由弧形臂的端部直接抵持第二支架372，本申请实施例对此不作严格限定。在其他一些实施例中，第一弹性件36和/或第二弹性件37也可以有其他设计结构，例如第一弹性件36和/或第二弹性件37整体为弹性体，弹性体的两端直 接接触对应的转动臂和固定架，本申请实施例对此不作严格限定。
请再次参阅图15至图17，示例性的，第一传动臂324的转动端324a可以安装于中轴31的安装空间中，通过实体轴结构转动连接中轴31，例如，第一传动臂324的转动端324a的转轴可以安装于中轴31的转轴孔中。其中，两个部件通过实体轴结构转动连接，是指两个部件通过实体的转轴实现相互转动，转轴具有转动中心，两个部件绕该转动中心相对转动，该转轴可以是独立于两个部件之外的结构件，也可以固定连接其中一个结构件。第二传动臂326的转动端326a可以安装于中轴31的安装空间中，通过实体轴结构转动连接中轴31，例如，第二传动臂326的转动端326a的转轴可以安装于中轴31的转轴孔中。
示例性的，折叠组件3的多个同步齿轮329啮合第一传动臂324的转动端324a和第二传动臂326的转动端326a。其中，多个同步齿轮329安装于中轴31的安装空间中，同步齿轮329可以通过实体轴结构转动连接中轴31。
在本实施例中，多个同步齿轮329用于在折叠组件3的运动过程中，使第一传动臂324和第二传动臂326相对中轴31的转动角度保持同步，从而使第一固定架321和第二固定架322的转动角度保持同步，第一固定架321带动第一壳体1转动，第二固定架322带动第二壳体2转动，因此多个同步齿轮329能够使第一壳体1和第二壳体2在折叠装置10的运动过程中保持同步，以提高用户的使用体验。
示例性的，如图15和图17所示，第一传动臂324的滑动端324b可以安装于第一固定架321的第一滑槽321d中，且能够于第一滑槽321d中滑动，以相对第一固定架321滑动。第一阻尼件327安装于第一传动臂324的滑动端324b，例如可以安装于第一安装槽3241。第一固定架321的第一凹陷区321e位于第二凹陷区321f靠近中轴31的一侧。如图15所示，折叠组件3处于打开状态时，第一阻尼件327部分卡入第一凹陷区321e；如图17所示，折叠组件3处于闭合状态时，第一阻尼件327越过第一顶块321g、部分卡入第二凹陷区321f。
如图15和图16所示，第二传动臂326的滑动端326b可以安装于第二固定架322的第二滑槽322d中，且能够于第二滑槽322d中滑动，以相对第二固定架322滑动。第二阻尼件328安装于第二传动臂326的滑动端326b，例如可以安装于第二安装槽3261。第二固定架322的第三凹陷区322e位于第四凹陷区322f靠近中轴31的一侧。如图15所示，折叠组件3处于打开状态时，第二阻尼件328部分卡入第三凹陷区322e；如图16所示，折叠组件3处于闭合状态时，第二阻尼件328越过第二顶块322g、部分卡入第四凹陷区322f。
在本实施例中，由于折叠组件3设有第一阻尼件327和第二阻尼件328，第一阻尼件327用于在第一传动臂324与第一固定架321相对滑动的过程中提供阻尼力，第一固定架321用于连接折叠装置10的第一壳体1，第二阻尼件328用于在第二传动臂326与第二固定架322相对滑动的过程中提供阻尼力，第二固定架322用于连接折叠装置10的第二壳体2，在第一固定架321带动第一壳体1相对中轴31转动、第二固定架322带动第二壳体2相对中轴31转动的过程中，第一阻尼件327和第二阻尼件328提供一定的阻尼力，使得用户能够体验到较佳的机构操作感。

其中，第三转动臂38和第四转动臂39可以通过虚拟轴结构转动连接中轴31。第三转动臂38相对中轴31的转动中心和第一转动臂323相对中轴31的转动中心错开排布，第四转动 臂39相对中轴31的转动中心和第二转动臂325相对中轴31的转动中心错开排布。
请结合参阅图22至图24，图22是图5所示折叠组件3的结构示意图，图23是图22所示折叠组件3在另一角度的结构示意图，图24是图22所示折叠组件3处于闭合状态时的结构示意图。
一些实施例中，第三转动臂38的第一端381可以通过实体轴结构转动连接第一遮挡板34。此时，第三转动臂38的一端转动连接中轴31，第一遮挡板34转动连接第三转动臂38的另一端。第四转动臂39的第一端391可以通过实体轴结构转动连接第二遮挡板35。此时，第四转动臂39的一端转动连接中轴31，第二遮挡板35转动连接第四转动臂39的另一端。
第一遮挡板34滑动连接第一固定架321，第二遮挡板35滑动连接第二固定架322。其中，第一遮挡板34与第一固定架321的滑动连接结构和/或第二遮挡板35与第二固定架322的滑动连接结构，可以采用滑槽与滑块的配合结构，本申请实施例对此不作严格限定。
在本实施例中，第一遮挡板34通过第一转动臂323转动连接中轴31并滑动连接第一固定架321，第二遮挡板35通过第二转动臂325转动连接中轴31并滑动连接第二固定架322，在第一固定架321和第二固定架322相对中轴31转动的过程中，第一遮挡板34和第二遮挡板35亦相对中轴31转动。
其中，如图22和图23所示，折叠装置10处于打开状态时，第一遮挡板34遮挡第一固定架321与中轴31之间的至少部分间隙，第二遮挡板35遮挡第二固定架322与中轴31之间的至少部分间隙。故而，第一遮挡板34和第二遮挡板35能够实现对折叠组件10的部分间隙的遮挡，有利于折叠组件10实现打开状态时的缝隙自遮挡，提高了折叠组件10的可靠性。
