本申请实施例提供一种可折叠电子设备，包括：柔性显示屏、铰链组件和位于铰链组件两侧的两个中框，两个所述中框通过所述铰链组件转动相连，所述柔性显示屏铺设在所述铰链组件和所述中框上；
所述铰链组件包括主轴机构以及位于所述主轴机构两侧的两个转动机构，两个所述转动机构分别与所述主轴机构转动相连；
每个所述转动机构包括至少一个摆动件和至少一个连接件，所述摆动件的第一端与所述主轴机构转动相连，所述摆动件的第二端与所述连接件转动相连，所述连接件与所述中框相连；
所述连接件上设置有滑槽，所述滑槽的槽口面向所述柔性显示屏，所述滑槽从所述连接件上面向所述柔性显示屏的一侧朝向所述连接件上背向所述柔性显示屏的一侧延伸；所述摆动件上设置有与所述滑槽配合的滑动件，所述滑动件背向所述主轴机构的一侧与所述滑槽的内壁相抵接；
当所述电子设备处于展平状态时，所述滑动件通过所述槽口部分位于所述滑槽内；当所述电子设备在折叠的过程中，所述滑动件沿着所述滑槽的延伸方向滑动，且当所述电子设备处于折叠状态时，所述滑动件嵌入所述滑槽内。
也即转动机构相对主轴机构转动的整个过程中，摆动件上的滑动件在滑槽内滑动，同时滑动件背向主轴机构的一侧与滑槽内壁抵接，也就是说电子设备处于折叠状态和展平状态，以及在上述状态之间切换的过程中，滑动件背向主轴机构的一侧与滑槽内壁抵接，这样摆动件就能够对连接件起到抵接支撑的作用，减少了摆动件和连接件之间的连接间隙和虚位，也就减小了铰链组件内的连接间隙和虚位，在电子设备跌落或是碰撞过程中，摆动件的滑动件对连接件的滑槽的抵接支撑，能够减少或避免连接件朝向主轴机构的错动，提升了电子设备的可靠性。同时也避免了在电子设备处于折叠状态时，由于连接件的错动而导致容屏空间的减小，减小或避免了在跌落或碰撞等过程中对柔性显示屏的损伤，进一步提升了电子设备的可靠性。
在一种可能的实现方式中，所述第二端与所述连接件背向所述主轴机构的一端相连；
所述连接件面向所述柔性显示屏的一面上设置有相对的两个所述滑槽，所述第二端相对两侧的端面上设置有所述滑动件。这样有助于进一步提升摆动件对连接件的抵接支撑作用，进一步减小或避免连接件的窜动，提升电子设备的可靠性。
另外，摆动件的第二端与连接件背向主轴机构的一端相连，可以减小连接件和摆动件在x方向上的总连接长度，有助于减小铰链组件的宽度，有助于电子设备的轻薄化设计。
在一种可能的实现方式中，所述连接件面向所述柔性显示屏的一面上开设有装配槽，所述装配槽至少包括相对的第一侧壁和第二侧壁，所述第一侧壁和所述第二侧壁上分别开设有所述滑槽；
所述装配槽还包括与所述第一侧壁和所述第二侧壁相邻的第三侧壁，所述第三侧壁位于所述连接件背向所述主轴机构的一端，所述第二端转动设置在所述第三侧壁上，且所述第二端两侧的端面分别与所述第一侧壁和所述第二侧壁抵接。这样第二端就能够对装配槽起到抵接支撑的作用，也即摆动件能够对连接件起到y方向上的支撑，减小了连接件和摆动件在y方向上的连接间隙和虚位，减少和避免了在电子设备跌落或碰撞等场景中，连接件在y方向上的窜动，进一步提升了电子设备的可靠性。
在一种可能的实现方式中，还包括第一销轴，所述第二端上具有第一转动部，所述第三侧壁上具有连接部，所述第一转动部和所述连接部通过所述第一销轴转动连接。从而实现了摆动件第二端与连接件的转动相连。
在一种可能的实现方式中，所述第一转动部包括第一转动臂和第二转动臂，所述第一转动臂和所述第二转动臂之间具有间隙；
所述第三侧壁上开设有第一避让孔和第二避让孔，所述连接部位于所述第三侧壁的外壁面上，且所述连接部位于所述第一避让孔和所述第二避让孔之间，所述第一转动臂和所述第二转动臂分别穿设在所述第一避让孔和所述第二避让孔上，所述第一转动臂和所述第 二转动臂通过所述第一销轴与所述连接部转动相连。从而实现了摆动件第二端与连接件装配槽的第三侧壁之间的转动配合。同时摆动件的第二端与连接件的连接位置处更加的远离主轴机构，有助于进一步减小连接件和摆动件在x方向上的总连接长度，减小铰链组件的宽度，有助于电子设备的轻薄化设计。
在一种可能的实现方式中，所述滑动件背向所述主轴机构的一侧侧面形成抵接面，所述滑槽背向所述主轴机构的一侧侧壁面与所述抵接面抵接，所述抵接面和所述侧壁面均为弧形面，且所述侧壁面与所述抵接面的形状相匹配。这样有助于增大滑槽和滑动件的接触面积，提升抵接支撑强度，进而提升摆动件对连接件的支撑强度，有助于进一步减小连接件与摆动件之间的连接间隙和虚位，提升电子设备的可靠性。
在一种可能的实现方式中，所述滑动件为楔形块，所述楔形块的薄端邻近所述滑槽的槽底设置。有助于增大滑动件与滑槽的接触面积，进而提升两者之间的抵接支撑强度，进一步减小铰链组件中的连接间隙和虚位，提升电子设备的可靠性。
在一种可能的实现方式中，所述第一端上具有第二转动部，所述第二转动部的两侧外边缘具有圆弧面，所述主轴机构内具有与所述圆弧面转动配合的圆弧部，所述摆动件通过所述第二转动部与所述主轴机构转动相连。
在一种可能的实现方式中，每个所述转动机构还包括至少一个联动件，所述联动件的一端与所述连接件连接，所述联动件的另一端与所述主轴机构转动相连，且分别位于两个所述转动机构中的两个联动件通过所述主轴机构转动相连，以使其中一个联动件相对所述主轴机构转动时带动其中另一个联动件相对所述主轴机构转动。这样就实现了第一中框和第二中框之间的联动，使第一中框和第二中框能够同步转动，在展开或折叠电子设备时，只需驱动其中一侧中框转动就能够带动另一侧中框转动，实现电子设备的折叠或展开，操作更加便捷，有助于提升使用体验。
在一种可能的实现方式中，所述连接件上开设有配位槽，所述配位槽从所述连接件面向所述主轴机构的一端延伸至所述连接件背向所述主轴机构的一端，所述联动件的一端插设在所述配位槽内。这样，联动件一端通过插设的方式设置在配位槽内，可便于拆卸与安装，便于实现。
另外，由于配位槽贯穿在连接件的宽度方向(x方向上)，联动件一端背向主轴机构的一侧就能够位于连接件背向主轴机构的一端上，在实现联动件与连接件之间连接的同时，也能够增强联动件与连接件之间的连接强度，并减小在x方向上联动件和连接件之间的总长度，有助于减小铰链组件的宽度，有助于电子设备的轻薄化设计。
在一种可能的实现方式中，所述主轴机构包括齿轮组件，所述联动件的另一端上具有齿轮部，所述齿轮部与所述主轴机构转动相连，且所述齿轮部与所述齿轮组件啮合。
在一种可能的实现方式中，每个所述转动机构还包括支撑件，所述支撑件一端邻近所述主轴机构设置，所述连接件位于所述支撑件背向所述主轴机构的一端上，所述连接件与所述支撑件转动相连。
在一种可能的实现方式中，所述支撑件上设置有弧形导轨件，所述连接件的两端上开设有弧形导轨槽，所述弧形导轨件与所述弧形导轨槽转动配合，所述支撑件与所述连接件通过所述弧形导轨槽和所述弧形导轨件的配合实现转动相连。
在一种可能的实现方式中，所述转动机构还包括至少一个联动件，所述联动件一端与 所述连接件连接，所述联动件的另一端与所述主轴机构转动相连，且位于两个所述转动机构中的两个联动件通过所述主轴机构转动相连，以使其中一个联动件相对所述主轴机构转动时带动其中另一个联动件相对所述主轴机构转动；
所述联动件与所述支撑件转动相连。这样可以减少支撑件的运动冗余，从而减小支撑件的设置间隙以及虚位，进一步减小铰链组件内的连接间隙和虚位，进一步提升电子设备的可靠性。
在一种可能的实现方式中，还包括第二销轴，所述支撑件上设置有弧形轨迹槽，所述第二销轴穿设在所述弧形轨迹槽内并沿所述弧形轨迹槽移动，所述第二销轴与所述联动件相连，从而使联动件通过第二销轴与弧形轨迹槽的配合实现了与支撑件的转动相连。

具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请，下面将结合附图对本申请实施例的实施方式进行详细描述。
其中，本申请实施例提供的可折叠的电子设备可以包括但不限于为手机、平板电脑、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、手持计算机、触控电视、对讲机、上网本、POS机、个人数字助理(personal digital assistant，PDA)、可穿戴设备、虚拟现实设备等可折叠的固定终端或移动终端。
本申请实施例中，以该可折叠电子设备为折叠手机为例进行说明，其中，该折叠手机可以为屏幕外折的可折叠手机，或者该折叠手机也可以为屏幕内折的可折叠手机，或者，该折叠手机也可以是屏幕内折附加外屏的可折叠手机。
以下以屏幕内折的可折叠手机为例，结合附图对本申请实施例提供的可折叠电子设备 及铰链组件进行详细的说明。
图1为本申请实施例提供的一种可折叠电子设备处于折叠状态的结构示意图，图2为本申请实施例提供的一种可折叠电子设备处于中间状态的结构示意图，图3为本申请实施例提供的一种可折叠电子设备处于展平状态的结构示意图。
参见图1和图2所示，该可折叠电子设备100可以至少包括铰链组件30和两个中框，例如，第一中框10和第二中框20，第一中框10和第二中框20位于铰链组件30的两侧，第一中框10和第二中框20分别与铰链组件30相连，具体的，第一中框10和第二中框20可以与铰链组件30中的连接件相连。
而且，两个中框通过铰链组件30转动相连，从而使两个中框能够相对转动，也即第一中框10和第二中框20可以发生相对的转动。
参见图1所示，第一中框10和第二中框20能够相对折叠至闭合状态，示例性的，第一中框10和第二中框20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)，此时电子设备100处于闭合状态，也称折叠状态。
参见图2所示，第一中框10和第二中框20能够相对转动(折叠或展开)至中间状态，以使电子设备100处于中间状态。
参见图3所示，第一中框10和第二中框20能够相对展开至打开状态。示例性的，第一中框10和第二中框20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°)，此时电子设备处于打开状态，也称展平状态。
其中，图2所示的中间状态，可以为打开状态与闭合状态之间的任意状态。也即电子设备100可以通过铰链组件30的运动，在打开状态(也即展平状态)与闭合状态(也即折叠状态)之间相互切换。
本申请实施例中，如图1和图3中所示，以电子设备100处于展平状态或折叠状态时，电子设备100的宽度方向为x方向，电子设备100的长度方向为y方向，电子设备100的厚度方向为z方向。
其中，需要说明的是，电子设备100可以只包括两个中框，即第一中框10和第二中框20的数量可以均为一个，使电子设备100处于折叠状态时，第一中框10和第二中框20相对折叠成两层，参见图1所示，电子设备100包括一个第一中框10、一个第二中框20以及一个铰链组件30，第一中框10和第二中框20通过铰链组件30转动相连，第一中框10和第二中框20相对折叠，使电子设备100呈两层的形态。
或者，电子设备100也可以包括多个中框，也即第一中框10、第二中框20以及铰链组件30的数量可以为多个，相邻的第一中框10和第二中框20之间通过一个铰链组件30相连，使电子设备100可以折叠呈多层的形态。例如，电子设备100可以包括有两个第一中框、一个第二中框和两个铰链组件，两个第一中框位于第二中框的两侧，且两个第一中框分别通过一个铰链组件与第二中框转动相连，其中一个第一中框可以和第二中框相对折叠，其中另一个第一中框也可以与第二中框相对折叠，使电子设备100处于折叠状态时，第一中框和第二中框相对折叠成三层的形态。当其中一个第一中框和第二中框相对展开至展平状态(如两者大致呈180°)时，电子设备100呈展平状态。
参见图2和图3所示，该电子设备100还可以包括有可折叠的柔性显示屏40，其中，柔性显示屏40铺设在铰链组件30和两个中框上，具体的，柔性显示屏40可以设置在第 一中框10、第二中框20以及铰链组件30的同一侧表面上。当第一中框10和第二中框20相对折叠时，柔性显示屏40贴附在第一中框10和第二中框20上，与铰链组件30相对的部分柔性显示屏40弯折，铰链组件30围成容屏空间33，弯折的柔性显示屏40至少部分位于该容屏空间33(参照图13所示)。当第一中框10和第二中框20相对展开时，柔性显示屏40也随之展开。
其中，对于屏幕内折的可折叠电子设备100，柔性显示屏40设置在第一中框10、第二中框20以及铰链组件30的内侧表面。例如，如图2和图3中所示，在本申请实施例中，以柔性显示屏40位于第一中框10、第二中框20以及铰链组件30的内侧表面为例进行说明。对于屏幕外折的可折叠电子设备100，柔性显示屏40设置在第一中框10、第二中框20以及铰链组件30的外侧表面。
需要说明的是，当电子设备100处于折叠状态时，第一中框10和第二中框20相邻且相对的两个表面分别为第一中框10和第二中框20的内侧表面，铰链组件30与第一中框10、第二中框20的内侧表面同一侧的表面为铰链组件30的内侧表面。第一中框10和第二中框20相背的两个表面分别为第一中框10和第二中框20的外侧表面，铰链组件30与第一中框10、第二中框20的外侧表面同一侧的表面为铰链组件30的外侧表面。
其中，在一些实施例中，该可折叠电子设备100也可以是笔记本电脑，笔记本电脑可以包括第一中框和第二中框，第一中框和第二中框能够相对折叠至闭合状态，使笔记本电脑处于闭合状态(也即折叠状态)。相应的，第一中框和第二中框从折叠状态起，相对展开至打开状态时，笔记本电脑处于打开状态(也即展平状态)。其中，在展平状态时，第一中框上的至少部分柔性显示屏可以用于图像等的显示，第二中框上的至少部分柔性显示屏可以作为虚拟键盘等。
本申请实施例中，第一中框10可以包括第一中板和第一边框，第一边框围设在第一中板的外周边缘上。第二中框20也可以包括第二中板和第二边框，第二边框围设在第二中板的外周边缘上。铰链组件30中的连接件322可以分别与第一中板和第二中板连接。
图4为本申请实施例提供的一种铰链组件处于展平状态时的内侧结构示意图，图5为本申请实施例提供的一种铰链组件处于展平状态时的外侧结构示意图，图6为本申请实施例提供的一种铰链组件处于展平状态时的侧视结构示意图，图7为本申请实施例提供的一种铰链组件处于折叠状态时的侧视结构示意图，图8为图5的局部结构放大图，图8a为本申请实施例提供的一种铰链组件的局部拆分示意图。
参见图4和图5所示，铰链组件30可以包括主轴机构31以及两个转动机构，两个转动机构位于主轴机构31的两侧，两个转动机构分别与主轴机构31转动相连，从而使两个转动机构能够相对转动，转动机构中的连接件322可以与电子设备100的中框相连。
其中，例如，参见图4和5所示，两个转动机构分别为第一转动机构32a和第二转动机构32b，第一转动机构32a与第二转动机构32b位于主轴机构31的两侧。其中，第一转动机构32a可以邻近第一中框10设置，第一转动机构32a可以与第一中框10连接，从而使第一中框10可以通过第一转动机构32a实现与主轴机构31转动配合。第二转动机构32b可以邻近第二中框20设置，第二转动机构32b可以与第二中框20连接，从而使第二中框20可以通过第二转动机构32b实现与主轴机构31转动配合。
其中，使两个中框相对转动，例如，使两个中框相对展开时，两中框分别带动两转动 机构相对展开，当电子设备100处于展平状态，第一转动机构32a、第二转动机构32b和主轴机构31处于打开状态，示例性的，参见图6所示，第一转动机构32a、第二转动机构32b和主轴机构31中相邻两者之间可以大致呈180°，此时铰链组件30也处于展平状态。
使两个中框相对折叠时，两个中框分别带动两转动机构相对折叠，当电子设备100处于折叠状态，参见图7所示，第一转动机构32a和第二转动机构32b合拢至闭合状态，此时铰链组件30也处于折叠状态。
其中，每个转动机构包括有摆动件321和连接件322，如图8所示，以第一转动机构32a为例，第一转动机构32a包括摆动件321和连接件322。具体的，连接件322可以位于摆动件321背向主轴机构31的一端。
其中，摆动件321相对的两端中，较邻近主轴机构31的一端为摆动件321面向主轴机构31的一端，较远离主轴机构31的一端为摆动件321背向主轴机构31的一端。相应的，在本申请实施例中，面向某一结构部件的一端(或一侧)指较邻近该结构部件的一端(或一侧)，背向某一结构部件的一端(或一侧)指较远离该结构部件的一端(或一侧)。
需要说明的是，摆动件321和连接件322的数量均可以为一个，也可以均为多个，例如，每个转动机构中包括有三个连接件322和三个摆动件321(参照图5所示)，三个连接件322可以沿着主轴机构31的轴向方向间隔设置，相应的，三个摆动件321也可以沿着主轴机构31的轴向方向间隔设置。
其中，结合图8和图8a所示，摆动件321的第一端321a与主轴机构31转动相连，摆动件321的第二端321b与连接件322转动相连，连接件322可以与第一中框10固定相连，这样摆动件321相对主轴机构31转动相连，摆动件321就能够通过连接件322带动第一中框10相对主轴机构31转动，从而使电子设备100的两中框能够通过铰链组件30实现相对转动。
而由于铰链组件30由主轴机构31、摆动件321以及连接件322等零部件之间连接形成，整体尺寸链较长，且为满足转动需求，铰链组件30中各零部件间多为转动连接，使的摆动件321、连接件322以及主轴机构31等零部件之间存在较多的连接间隙和虚位。当可折叠电子设备100在跌落或发生碰撞等场景中，由于铰链组件30中间隙和虚位的存在，可能会导致零部件的位置错动，如连接件322容易发生朝向主轴机构31的错位，降低了可折叠电子设备100的可靠性。尤其是当电子设备100处于折叠状态时，柔性显示屏40的弯折部分位于铰链组件30形成的容屏空间33内，连接件322朝向主轴机构31的错位，容易导致容屏空间33的减小，对柔性显示屏40造成损伤，使柔性显示屏40易出现失效的现象，对电子设备100的可靠性造成巨大的影响。
图9为本申请实施例提供的一种铰链组件内部的局部结构示意图，其中，图9为铰链组件内侧去除支撑件后的结构示意图，图10为本申请实施例提供的一种电子设备处于展平状态时的剖面局部结构示意图，图11为本申请实施例提供的一种电子设备处于中间状态的剖面局部结构示意图，图12为本申请实施例提供的一种电子设备处于折叠状态时的剖面局部结构示意图，图13为本申请实施例提供的一种电子设备处于折叠状态时的剖面正视图。
而在本申请实施例中，参见图9所示，摆动件321的第一端与主轴机构31转动相连，摆动件321的第二端与连接件322转动相连。在摆动件321上设置有滑动件3211，在连接 件322上设置有滑槽3221，滑动件3211位于滑槽3221内并与滑槽3221配合。
结合图10所示，滑槽3221的槽口面向柔性显示屏40，滑槽3221从连接件322上面向柔性显示屏40的一侧朝向连接件322上背向柔性显示屏40的一侧延伸，也即滑槽3221延伸分布在连接件322的厚度方向(z方向)上，滑动件3211可以沿着滑槽3221滑动，且滑动件3211在滑槽3221内滑动时，滑动件3211背向主轴机构31的一侧与滑槽3221的内壁相抵接。
其中，对滑槽3221的形状在本申请实施例中不作限制，能够在满足连接件322和摆动件321的转动配合的条件下，容纳滑动件3211，并使滑动件3211背向主轴机构31的一侧与滑槽3221的内壁相抵接即可。
具体的，当电子设备100处于展平状态时，参见图10所示，滑动件3211可以通过槽口部分的位于滑槽3221内，同时滑动件3211背向主轴机构31的一侧与滑槽3221背向主轴机构31的一侧内壁抵接，滑动件3211能够对连接件322起到支撑抵接的作用，也即摆动件321能够对连接件322起到如图中x方向的支撑力，减少了连接件322和摆动件321在x方向上的连接间隙和虚位，从而减小或避免了在跌落或碰撞等场景中，连接件322朝向主轴机构31方向的窜动，提升了电子设备100的可靠性。
参见图11所示，在电子设备100折叠的过程中，第一中框带动连接件322转动，连接件322相对摆动件321转动时，滑动件3211与滑槽3221转动配合，滑动件3211可以沿着滑槽3221的延伸方向滑动，同时滑动件3211背向主轴机构31的一侧与滑槽3221背向主轴机构31的一侧内壁抵接，结合图10和图11所示，在折叠的过程中，滑动件3211从槽口沿着滑槽3221的延伸方向朝向滑槽3221的底部滑动。
参见图12所示，当电子设备100处于折叠状态时，滑动件3211滑动至滑槽3221内，并整体嵌入滑槽3221内。同样的，滑动件3211背向主轴机构31的一侧仍与滑槽3221背向主轴机构31的一侧内壁抵接，滑动件3211对连接件322起到x方向的支撑力，减少连接件322和摆动件321在x方向上的连接间隙和虚位，减小或避免在跌落或碰撞等场景中连接件322的窜动，提升了电子设备100的可靠性。
也即电子设备处于折叠状态和展平状态，以及在上述状态之间切换的过程中，滑动件3211背向主轴机构31的一侧与滑槽3221内壁抵接，这样摆动件321就能够对连接件322起到抵接支撑的作用，减少了摆动件321和连接件322之间的连接间隙和虚位，也就减小了铰链组件30内的连接间隙和虚位。在电子设备100跌落或是碰撞过程中，摆动件321的滑动件3211对连接件322的滑槽3221的抵接支撑，能够减少或避免连接件322朝向主轴机构31的错动，提升了电子设备100的可靠性。
另外，也避免了在电子设备100处于折叠状态时，由于连接件322的错动而导致容屏空间33的减小，减小或避免了在跌落或碰撞等过程中对柔性显示屏40的损伤，进一步提升了电子设备100的可靠性。参见图13所示，在电子设备100处于折叠状态时，连接件322、摆动件321以及主轴机构31均用于形成容屏空间33，与铰链组件30相对的部分柔性显示屏40弯折并位于该容屏空间33内。使折叠状态时滑动件3211整体嵌入滑槽3221内，能够提升滑动件3211与滑槽3221之间的抵接面积，进而提升在折叠状态时摆动件321对连接件322的支撑强度。这样能够进一步保证避免了连接件322朝向主轴机构31方向的窜动，减小或避免了在电子设备100跌落或碰撞等时对容屏空间33的影响，从而减小 对容屏空间33内弯折的柔性显示屏40的损伤，进一步提升电子设备100的可靠性。

结合图14和图15所示，可以在连接件322上设置有至少两个相对的滑槽3221，摆动件321的第二端321b相对两侧的端面上可以设置有滑动件3211。具体的，第二端321b与连接件322背向主轴机构31的一端相连，可以在连接件322面向柔性显示屏40的一面上设置有滑槽3221(参照图11所示)，有助于进一步提升摆动件321对连接件322的抵接支撑作用，进一步减小或避免连接件322的窜动，提升电子设备100的可靠性。
另外，摆动件321的第二端321b与连接件322背向主轴机构31的一端相连，可以减小连接件322和摆动件321在x方向上的总连接长度，有助于减小铰链组件30的宽度，有助于电子设备100的轻薄化设计。
其中，参见图15所示，摆动件321的第二端321b上具有第一转动部3212，摆动件321的第二端321b通过第一转动部3212与连接件322转动相连。摆动件321的第一端321a上可以具有第二转动部3213，摆动件321的第一端321a通过第二转动部3213与主轴机构31转动相连。
具体的，第二转动部3213的两侧外边缘可以具有圆弧面3213a，主轴机构31内可以具有与该圆弧面3213a转动配合的圆弧部313(参照图13所示)，摆动件321可以通过该圆弧面3213a和圆弧部313转动配合实现与主轴机构31的转动连接。
例如，主轴机构31可以包括有主内轴311和主外轴312，主内轴311和主外轴312之间相连，主内轴311和主外轴312之间可以限定出圆弧部313，第二转动部3213的圆弧面3213a可以位于圆弧部313内，并沿着圆弧部移动。
其中，结合图15a和图15b所示，滑动件3211背向主轴机构31的一侧侧面为抵接面3211a，滑槽3221背向主轴机构31的一侧壁面3221a与该抵接面3211a抵接，从而实现摆动件321对连接件322的抵接支撑作用。具体的，抵接面3211a和侧壁面3221a可以均为弧形面，且抵接面3211a和侧壁面3221a的形状相匹配。例如，参见图15b所示，抵接面3211a为朝向主轴机构31方向凸起的圆弧面，则侧壁面3221a也为朝向主轴机构31方向凸起的圆弧面。这样有助于增大滑槽3221和滑动件3211的接触面积，提升抵接支撑强度，进而提升摆动件321对连接件322的支撑强度，有助于进一步减小连接件322与摆动件321之间的连接间隙和虚位，提升电子设备100的可靠性。
具体的，滑动件3211可以为楔形块(参照图15所示)，楔形块是指两端厚度不同的结构件，其中，楔形块的薄端可以邻近滑槽3221的底部设置，便于实现滑动件3211与滑槽3221的抵接和相对滑动。使滑动件3211为楔形块，在滑槽3221深度一定时，滑动件3211 为楔形块有助于增大滑动件3211与滑槽3221的接触面积，进而提升两者之间的抵接支撑强度，进一步减小铰链组件30中的连接间隙和虚位，提升电子设备100的可靠性。
当然，在一些示例中，滑动件3211也可以是方形块、圆柱体等。或者，滑动件3211的形状也可以是其他规则或不规则的形状。
其中，本申请实施例中，参见图14和图15a所示，连接件322面向柔性显示屏40的一面上可以开设有装配槽3222，装配槽3222至少可以包括有相对的第一侧壁3222a和第二侧壁3222b，第一侧壁3222a和第二侧壁3222b上分别开设有上述的滑槽3221。
参见图15a所示，装配槽3222还包括有第三侧壁3222c，第三侧壁3222c与第一侧壁3222a和第二侧壁3222b相邻，且第三侧壁3222c位于连接件322背向主轴机构31的一端，摆动件321的第二端321b转动设置在第三侧壁3222c上，装配槽3222还可以包括有底壁3222d(参照图16b所示)，第一侧壁3222a、第二侧壁3222b和第三侧壁3222c围设在底壁3222d上，且装配槽3222与第三侧壁3222c相对的一侧上具有避让开口，装配槽3222与底壁3222d相对的一侧上也具有避让开口，以避让摆动件321，便于摆动件321的转动。
其中，参见图16和图16a所示，摆动件321的第二端321b与第三侧壁3222c转动配合时，第二端321b两侧的端面可以分别与第一侧壁3222a和第二侧壁3222b抵接，这样第二端321b就能够对装配槽3222起到抵接支撑的作用，也即摆动件321能够对连接件322起到y方向上的支撑，减小了连接件322和摆动件321在y方向上的连接间隙和虚位，减少和避免了在电子设备100跌落或碰撞等场景中，连接件322在y方向上的窜动，进一步提升了电子设备100的可靠性。
例如，当电子设备100处于展平状态时，参见图16b所示，摆动件321的第二端321b部分位于装配槽3222内，第二端321b与第三侧壁3222c转动配合，结合图16a所示，第二端321b与第三侧壁3222c配合的部分两侧的端面分别与第一侧壁3222a和第二侧壁3222b抵接，摆动件321对连接件322能够起到y方向上的支撑，减小两者在y方向上的连接间隙和虚位。同时，摆动件321上的滑动件3211部分位于滑槽3221内，且滑动件3211背向主轴机构31的一侧与滑槽3221内壁抵接，摆动件321对连接件322能够起到x方向上的支撑，减小两者在x方向上的连接间隙和虚位。
当电子设备100由展平状态转动至折叠状态的过程中，结合图16b和图16c所示，摆动件321的第二端321b可以朝向装配槽3222的底壁3222d滑动。当电子设备100处于折叠状态时，结合图16c和图17所示，第二端321b可以嵌入在装配槽3222内，第二端321b相对两侧的端面仍可以分别与第一侧壁3222a和第二侧壁3222b抵接(参照图16a所示)，摆动件321对连接件322起到y方向上的支撑。同时，摆动件321上的滑动件3211嵌入滑槽3221内，滑动件3211背向主轴机构31的一侧与滑槽3221内壁抵接，摆动件321对连接件322起到x方向上的支撑。
图18为本申请实施例提供的又一种铰链组件的局部拆分示意图。
参见图18所示，第三侧壁3222c上具有连接部3223，摆动件321的第二端321b上的第一转动部3212和连接部3223可以通过第一销轴325转动连接，从而使摆动件321和连接件322转动相连。
具体的，第一转动部3212可以包括有第一转动臂3212a和第二转动臂3212b，其中，第一转动臂3212a和第二转动臂3212b之间具有间隙。在第三侧壁3222c上开设有第一避 让孔和第二避让孔，连接部3223位于第三侧壁3222c的外壁面上，且连接部3223位于第一避让孔和第二避让孔之间。
其中，第一转动臂3212a上可以具有第一连接孔，第二转动臂3212b上可以具有第二连接孔，连接部3223上开设有第三连接孔。摆动件321通过第一转动部3212设置在装配槽3222上时，第一转动臂3212a和第二转动臂3212b分别穿过第一避让孔和第二避让孔后，第一销轴325依次穿设在第一连接孔、第二连接孔和第三连接孔上，从而使第一转动臂3212a和第二转动臂3212b通过第一销轴325与连接部3223转动连接，进而实现摆动件321与连接件322的转动相连。这样，摆动件321的第二端与连接件322的连接位置更加的远离主轴机构31，有助于进一步减小连接件322和摆动件321在x方向上的总连接长度，减小铰链组件30的宽度，有助于电子设备100的轻薄化设计。
图18a为本申请实施例提供的一种铰链组件的局部结构示意图，图19为本申请实施例提供的再一种铰链组件的局部拆分示意图，图19a为本申请实施例提供的一种联动件和连接件配合的局部结构放大图，图19b为本申请实施例提供的一种联动件的背面结构示意图，图19c为本申请实施例提供的一种铰链组件在联动件和连接件处的剖面局部结构示意图，图20为本申请实施例提供的一种联动件的正面结构示意图，图21为本申请实施例提供的一种铰链组件在联动件处的剖面结构示意图。
本申请实施例中，参见图18a所示，每个转动机构还包括至少一个联动件323，每个转动机构中的联动件323的数量可以为一个，或者也可以为多个，联动件323的数量可以与连接件322或者是摆动件321的数量保持一致，例如，当连接件322的数量为三个时(参照图5所示)，联动件323的数量也可以是三个。
结合图19所示，联动件323一端与连接件322连接，联动件323的另一端与主轴机构31转动相连。具体的，在连接件322上可以开设有配位槽3226，配位槽3226从连接件322面向主轴机构31的一端延伸至连接件322背向主轴机构31的一端，联动件323的一端可以插设在配位槽3226内，从而使连接件322与联动件323连接，连接件322相对主轴机构31转动时，带动联动件323相对主轴机构31转动。联动件323一端通过插设的方式设置在配位槽3226内，可便于拆卸与安装，便于实现。
具体的，结合图19a和图19b所示，联动件323一端的两侧外壁上可以设置有插接件323a，配位槽3226相对的两侧壁上具有插接槽3226a，结合图19a和图19c所示，插接件323a可以插设在插接槽3226a内，联动件323一端可以通过插接件323a与插接槽3226a的插接配合实现与连接件322的连接。
而由于配位槽3226贯穿在连接件322的宽度方向(x方向上)，联动件323背向主轴机构31的一侧就能够位于连接件322背向主轴机构31的一端上，这样在实现联动件323与连接件322之间连接的同时，也能够增强联动件323与连接件322之间的连接强度，并减小在x方向上联动件323和连接件322之间的总长度，有助于减小铰链组件30的宽度，有助于电子设备100的轻薄化设计。
参见图20所示，在联动件323的另一端上可以具有齿轮部3231，结合图21所示，齿轮部3231可以通过转轴327与主轴机构31转动相连。
其中，分别位于两个转动机构中的两个联动件323通过主轴机构31转动相连，例如，参见图21所示，以第一转动机构32a中的联动件为第一联动件3230a，第二转动机构32b 中的联动件为第二联动件323b，第一联动件3230a和第二联动件323b通过主轴机构31转动相连。当转动第一中框10，第一中框10带动第一转动机构32a中的连接件322a转动，连接件322a带动第一联动件3230a相对主轴机构31转动，进而使第一联动件3230a带动第二联动件323b相对主轴机构31转动。第二联动件323b通过第二转动机构32b中的连接件322b可带动第二中框20转动，实现了第一中框10和第二中框20之间的联动，使第一中框10和第二中框20能够同步转动。这样在展开或折叠电子设备100时，只需驱动其中一侧中框转动就能够带动另一侧中框转动，实现电子设备100的折叠或展开，操作更加便捷，有助于提升使用体验。
具体的，参见图21所示，主轴机构31内可以设置有齿轮组件314，联动件323的齿轮部3231可以与齿轮组件314啮合，当第一联动件3230a相对主轴机构31转动时，第一联动件3230a通过齿轮部3231带动齿轮组件314转动，进而通过齿轮组件314带动第二联动件323b转动。
其中，如图21所示，可以仅在联动件323的齿轮部3231的部分外表面上设置有齿结构3231a。或者，在一些示例中，也可以在整个齿轮部3231的外表面上设置有齿结构。
图22为本申请实施例提供的又一种铰链组件的局部拆分示意图，图23为本申请实施例提供的一种支撑件和联动件的装配示意图。
本申请实施例中，参见图22所示，每个转动机构还包括有支撑件324，支撑件324一端邻近主轴机构31设置(参照图8所示)，其中，支撑件324可以位于摆动件321、联动件323邻近柔性显示屏40的一侧，连接件322位于支撑件324背向主轴机构31的一端上。
连接件322与支撑件324转动相连，连接件322转动时，连接件322首先与支撑件324发生相对转动，进而带动支撑件324相对主轴机构31转动。连接件322、摆动件321以及支撑件324共同形成用于容纳柔性显示屏40的容屏空间33(参照图13所示)。
支撑件324可以为支撑门板，支撑门板沿着主轴机构31的轴向方向延伸。每个转动机构可以包括一个支撑件324，支撑件324可以是一整个支撑门板，或者，支撑件324也可以是有多个门板拼接形成的。
具体的，参见图22所示，在支撑件324上可以设置有多个弧形导轨件3241，连接件322的两端上开设有弧形导轨槽3227，弧形导轨件3241可插入弧形导轨槽3227内，并沿着弧形导轨槽3227滑动，从而使弧形导轨件3241与弧形导轨槽3227实现转动配合，进而使支撑件324和连接件322通过弧形导轨件3241和弧形导轨槽3227的配合实现转动相连。
其中，联动件323与支撑件324可以转动相连，这样可以减少支撑件324的运动冗余，从而减小支撑件324的设置间隙以及虚位，进一步减小铰链组件30内的连接间隙和虚位，提升电子设备100的可靠性。
参见图22和图23所示，在支撑件324上可以设置有弧形轨迹槽3242，第二销轴326可以穿设在该弧形轨迹槽3242内，并沿着弧形轨迹槽3242移动，而联动件323可以与该第二销轴326相连，从而使联动件323和支撑件324可以通过第二销轴326和弧形轨迹槽3242的配合实现转动连接。
具体的，联动件323的一端可以包括第一连接臂3232a和第二连接臂3232b，第一连接臂3232a和第二连接臂3232b之间具有间隙，参见图23所示，弧形轨迹槽3242位于第 一连接臂3232a和第二连接臂3232b之间，在第一连接臂3232a和第二连接臂3232b上分别设置有第四连接孔，第二销轴326的中段穿设在弧形轨迹槽3242内，第二销轴326的两端分别穿设在第四连接孔内，从而通过第二销轴326和弧形轨迹槽3242实现了联动件323和支撑件324的转动相连，便于实现，且便于拆卸与安装。
