具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。
当前，随着柔性屏技术的发展，基于柔性屏的可折叠设备成为目前电子设备的设计趋势之一。
图1是本申请实施例提供的一种可折叠电子设备1000的结构示意图。图2为图1所示电子设备1000的结构分解图。
可折叠电子设备1000可以是手机、平板电脑、手表、电子阅读器、笔记本电脑、可穿戴设备等具有折叠功能的电子设备。图1所示实施例以左右左折叠的可折叠手机为例进行说明。
应理解，图1所示结构仅为示意性结构，本申请实施例也适用于上下折叠的电子设备。
参考图1和图2，以左右折叠方式的可折叠电子设备为例，电子设备1000可以包括柔性显示屏10、第一壳体20、第二壳体30以及主轴部40。为方便说明，本申请实施例以读者阅读附图的视角规定上下左右，但这并不构成对本申请实施例的限定。
其中，第一壳体20和第二壳体30分别与主轴部40的两侧连接，并且关于主轴部40 对称。在电子设备1000折叠或展开的过程中，第一壳体20和第二壳体30可以绕主轴部40转动。
图1中填充有电阵的图案可以示意性地表示柔性显示屏10。柔性显示屏10可以具有柔韧性强和可弯曲的特点，可以给用户提供基于可弯折特性的新交互方式。柔性显示屏10的显示面板例如可以采用液晶柔性显示屏(liquid crystal display，LCD)，有机发光二极管(organic light-emitting diode，OLED)，有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrix organic light emitting diode，AMOLED)，柔性发光二极管(flex light-emitting diode，FLED)，量子点发光二极管(quantum dot light emitting diodes，QLED)等中的任意一种，本申请实施例对此不做限定。
在一些实例中，第一壳体20可以包括第一侧边框201、第一盖体220，第二壳体30可以包括第二侧边框301和第二盖体302。
柔性显示屏10可以包括与第一盖体202对应的第一显示部101、与第二盖体302对应的第二显示部102，以及与同步连接机构40对应的可折叠显示部103。可折叠显示部103可以连接在第一显示部101与第二显示部102之间。
在一种可能的实现方式中，第一显示部101安装于第一盖体202上，第二显示部102安装于第二盖体302上。
第一侧边框201可以环绕在第一盖体202的外周，且环绕在第一显示部101的外周。第一显示部101可以与该第一盖体202平行间隔设置，且第一显示部101可以与该第一盖体202位于第一侧边框201的两侧。第一显示部101与该第一盖体202之间的间隔空间可以用于设置可折叠电子设备1000的器件，如天线、电路板组件等。
第二侧边框302可以环绕在第二盖体302的外周，且环绕在第一显示部102的外周。第一显示部102可以与该第二盖体302平行间隔设置，且第一显示部102可以与该第二盖体302位于第二侧边框302的两侧。第一显示部102与该第二盖体302之间的间隔空间可以用于设置可折叠电子设备1000的器件，如天线、电路板组件等。
在本申请提供的一种实施例中，盖体与侧边框可以为可折叠电子设备1000的壳体的两个部分，盖体与侧边框可以相连，且该相连的形式可以不属于如卡接、粘粘、焊接、铆接、间隙配合等装配方式。盖体与侧边框之间的连接关系通常很难被分割。在本申请提供的另一种实施例中，盖体与侧边框可以是两个不同的部件。通过将盖体与侧边框装配在一起，可以形成可折叠电子设备1000的壳体。
由于壳体20与壳体30关于主轴部40对称。因此，下文描述中，为了简洁起见，以一侧为例进行描述，另一侧相应的组件或者结构件的位置以及彼此的关系，可以相应的理解。
在一些实施例中，在第一壳体20内部放可以设置第一连接组件41，该第一连接组件41的一侧与第一壳体20连接，另一侧与主轴部43连接。相应的，在第二壳体30内部放可以设置第二连接组件42，该第二连接组件42的一侧与第二壳体30连接，另一侧与主轴部43连接。其中，第一连接组件41与第二连接组件42可以关于主轴部43对称。
图3示出了图1所示电子设备1000在不同状态下的示意性结构图(a图为展开态，b图为中间态，c图为折叠态)。
通常，可折叠电子设备1000具备展开态和折叠态，以及介于展开态和折叠态之间的中间态。
可折叠电子设备1000的展开态可以理解为：第一壳体20与主轴部40之间的夹角为180度，也即第一壳体的屏幕所在平面与主轴部正面在同一个平面。由于对称，第二壳体30与主轴部30之间的夹角也为180度。此时，电子设备1000以最大角度打开，呈现出最大的屏幕面积。
可折叠电子设备1000的折叠态可以理解为：第一壳体20与主轴部40之间的夹角为90度，也即第一壳体的屏幕所在平面与主轴部正面相垂直。由于对称，第二壳体30与主轴部30之间的夹角也为90度。此时，电子设备1000的两个壳体被叠放在一起，便于用户收纳。
可折叠电子设备1000的中间态可以理解为：第一壳体20与主轴部40之间的夹角在90度至180度之间。
还应说明，由于壳体存在一定的厚度，所以在折叠过程中，第一壳体29绕主轴部40的转动并不是圆周转动，而是边转动边远离主轴部40。换言之，第一壳体20在折叠中，沿其底边方向远离主轴部。从而，折叠态下的电子设备1000，其主轴部40的外表面暴露于外界。
对电子设备1000的折叠过程进行说明。以第一壳体20受到外力为例，该外力带动第一壳体20沿其底边方向远离主轴部40，并且向下转动，从而其与主轴部40的夹角逐渐变小，同时，第一壳体20的运动意味着其连接的第一滑动组件41也沿其底边方向远离主轴部43，另一侧与第二壳体连接的第二滑动组件42与第一滑动组件41运动同步，从而第二壳体30也被带动运动，并且其运动矢量与第一壳体20的运动矢量关于主轴部43的轴线对称，从而完成同步运动。
电子设备1000的展开运动可以相应的理解，在此不再展开描述。
在目前的方案中，一般第一滑动组件41和第二滑动组件42是相互配合的齿轮组件，并且通过在齿轮连杆上增加凹凸轮以实现阻尼力，但由于齿轮占用空间较大，使得转轴部103的尺寸较大，不利于用户携带，并且价格相对昂贵，因而，需要提供一种大小更小的转轴部。
本申请实施例提供一种同步连接机构，该机构主要由连杆组成，其占用空间更小，从而有利于减少机构整体尺寸，进而有利于减少电子设备1000的尺寸。
结合图4至图13对本申请实施例提供的同步连接机构50和可折叠电子设备2000进行说明。
应理解，可折叠电子设备2000与前述电子设备1000的主要区别在于同步连接机构，其余部件可参照上文相应的描述，为避免冗余，在此不再赘述。
图4示出了电子设备2000的示意性结构图。图5为图4所示的电子设备2000的示意性结构分解图。
结合图4和图5，示意性地，电子设备2000包括一个或多个同步连接机构50，同步连接机构50的两侧分别用于连接第一壳体20和第二壳体30。
同步连接机构50，包括：第一滑动组件51、第二滑动组件52和连接组件53。
连接组件53用于连接第一滑动组件52和第二滑动组件53。
连接组件53包括主轴部531和旋转件532，旋转件532与主轴部531转动连接，旋转件532绕第一轴线旋转，第一轴线垂直于第一方向，第一方向为主轴部531的轴线所在的方向。
第一滑动组件51和第二滑动组件52设置于主轴部531在第二方向上的两侧，第二方向垂直于第一方向，并且垂直于第三方向，第三方向为第一轴线所在的方向。
第一滑动组件51与旋转件532的第一位置相连接，第二滑动组件52与旋转件532的第二位置相连接，第一位置与第二位置关于第一轴线中心对称。
主轴部531包括第一滑动轨道5311和第二滑动轨道5312，第一滑动轨道5311和第二滑动轨道5312关于主轴部531的轴线对称。
从而，第一滑动组件51在第一外力作用下可沿第一滑动轨道5311运动，且通过旋转件532带动第二滑动组件52沿第二滑动轨道5312运动，其中，第一滑动组件51在第二方向的运动分量与第二滑动组件52在第二方向的运动分量大小相同、方向相反，第一滑动组件51在第三方向的运动分量与第二滑动组件52在第三方向的运动分量大小相同、方向相同，以使第一滑动组件51和第二滑动组件52关于主轴部531折叠或者展开。
以下结合图6至图8对本申请实施例提供的同步连接机构50的各部件配合的原理进行说明。
图6示出了不同状态下(展开态、中间态、折叠态)轨道内滑动组件的位置。
图7示出了不同状态下(展开态、中间态、折叠态)旋转件的旋转角度。
图8示出了轴线方向上滑动组件相对于主轴部的转动角度。
由前述描述可知，折叠过程中，第一壳体20可在外力作用下，带动其连接的第一滑动组件51远离主轴部53，也即第一滑动组件51在第一方向上远离主轴部53，记第一滑动组件51在第一方向的运动分量为X11，以及此时为第一方向的负方向，此外，由于第一壳体20向下折叠，因而第一滑动组件51在第一轴线所在方向还存在运动分量，记作X12。
参见图6的a图，第一滑动组件51处于位置#1，位置#1为其行程中距离主轴部53最近的位置，第一滑动组件51处于第一滑动轨道5311的占比最高，此时也对应于同步连接机构50的展开态，如图8的a图所示，第一滑动组件51与主轴部531的夹角为180度，如图6的b图所示，第一滑动组件51在外力的作用下可到达位置#2，位置#2在第一方向上与主轴部53的距离，相比于位置#1在第一方向上与主轴部53的距离更大，同时，第一滑动组件51处于第一滑动轨道5311的占比相比于a图降低，也即伸出轨道的部分增加，如图8的b图所示，第一滑动组件51与主轴部531的夹角小于180度但大于90度。应理解，外力一定的情况下，第一滑动组件51在第一方向的运动分量X11是可以确定的，由于第一滑动组件51收容于第一滑动轨道5311内，也即第一滑动组件51只能沿着第一滑动轨道5311运动，因此，当第一滑动组件51远离主轴部53运动时，其在第一轴线方向的运动量X12也是唯一确定的。
由于第一滑动组件51与旋转件532的第一位置相连，因而第一滑动组件51带动旋转件532的第一位置也向第一方向负方向运动，而由于旋转件532转动连接于主轴部53上，因而其只能绕第一轴线进行旋转运动，如图7的a图所示，当同步连接机构50处于展开态时，旋转件532处于第一状态，当旋转件532的第一位置被带动向第一方向负方向运动，使得旋转件532逆时针旋转至如图7的b图所示的状态，因而，旋转件532上的第二位置也相应的改变，由于第二位置与第一位置关于第一轴线中心对称，以及旋转件532的第二位置与第二滑动组件52相连接，因此第二滑动组件52在第一方向的运动分量与第一滑动组件51在第一方向的运动分量方向相反，大小相同。又由于，第一滑动轨道5311和第二滑动轨道5312关于主轴部531的轴线对称，因此，第二滑动组件52在第一轴线所在方向 的运动分量与第一滑动组件51在第一轴线所在方向的运动分量方向相同，大小相同。
如图6的c图所示，第一滑动组件51在第一方向处于距离主轴部531最大的位置处，此时其伸出第一滑动轨道5311的部分占比达最大，这样，其连接的第一壳体20在第一轴线方向上可以处于主轴部531之下，也即能够折叠出来。如图7的c图所示，旋转件532继续逆时针旋转，到达其第三状态。参见图8的c图，此时第一滑动组件51与主轴部531的夹角减少至90度。
在一些实施例中，如图5所示，同步连接机构50还包括盖板54，盖板54与主轴部531相对设置，盖板54设置于主轴部531靠近旋转件532的一侧，盖板54用于对主轴部531和旋转件532起到保护作用，避免其在折叠状态下直接暴露于外界而导致组件易被破坏并且不美观等等。
结合图9和图10对第一滑动组件51进一步说明，由于第二滑动组件52与之关于主轴部53对称，因此可以相应理解，为便于简洁，以单侧为例说明。
在一些实施例中，如图9和图10所示，第一滑动组件51包括第一连接件511、第二连接件512和第三连接件513，其中，第一连接件511和第三连接件513设置于第二连接件512在第二方向上的两侧，其中，第一连接件511与第二连接件512固定连接；第三连接件513的一端与第二连接件512转动连接，第三连接件513的另一端与旋转件532在第一位置处连接；从而，当第三连接件513在第一滑动组件51和第二滑动组件52折叠/展开时，可以沿第三方向移动。
在一些可能的实现方式中，第一连接件511与第二滑动件512一体成型，在另一些可能的实现方式中，第一连接件511与第二滑动件512为两个独立加工的零件，组装到一起。
在一些可能的实现方式中，为使得第二连接件512和第三连接件513转动连接，并且第三连接件513和旋转件532连接，第二连接件512靠近第三连接件513的一侧包括沿第一方向设置的第一凸台5121和第二凸台5122，第一凸台5121设置有第一孔51211，第二凸台5122设置有第二孔51221，第一孔51211的轴线和第二孔51221的轴线共线，并且平行于第一方向；旋转件532在第一位置处设有通孔5321，通孔5321的深度方向平行于第三方向；第三连接件513包括第一连接部5131、第二连接部5132和连接杆5133，连接杆5133的长度方向平行于第一方向，第一连接部5131套设于连接杆5133上，其中，第二连接部5132伸入通孔5321中，连接杆5133的两端分别位于第一孔51211和第二孔51221中。
可以理解，第一连接部5131位于第一凸台5121和第二凸台5122之间
需要说明的是，第一孔51211和第二孔51221至少有一个孔为通孔，以便于加工时可以使得连接杆5133穿过该两个孔。此外，一端并不能狭义的理解为一定是一个点，还可以认为是连接杆5133上包括端点的一部分，例如，可以认为第一端是距离端点2mm以内的部分。为实现第三连接件513在第一滑动组件51和第二滑动组件52折叠/展开时，沿第一方向移动，第二连接件512、第三连接件513以及旋转件532三者的连接关系可以有多种方式，结合图9和图10分别进行说明。
如图9所示，第一凸台5121和第二凸台5122在第一方向上的距离L，大于第一连接部5131沿所述第一方向的长度。从而，第一连接部5131可以相对于第二连接件512沿第一方向移动，也即第三连接件513可以相对于第二连接件512沿第一方向移动。
如图10所示，第二连接部5132在与第三方向垂直的截面上的面积，小于通孔5321 在与第三方向垂直的截面上的面积。该面积关系可以存在如下可能性：(a)、第二连接部5132与通孔5321的孔壁之间在第一方向存在间隙；(b)、第二连接部5132与通孔5321的孔壁之间在第二方向存在间隙；(c)、第二连接部5132与通孔5321的孔壁之间在第一方向和第二方向都存在间隙。
在一种可能的实现方式中，第二连接部5132与通孔5321的孔壁之间在第一方向存在间隙，从而第二连接部5132可以相对于通孔5321沿第一方向移动，也即第三连接件513可以相对于旋转件532沿第一方向移动。
此外，第三连接件513还可以相对于旋转件532沿第二方向移动。在一种可能的实现方式中，第二连接部5132与通孔5321的孔壁之间在第二方向存在间隙，从而第二连接部5132可以相对于通孔5321沿第二方向移动，也即第三连接件513可以相对于旋转件532沿第二方向移动。
结合图11对两个滑动轨道进一步说明。
在一些实施例中，如图11所示，第一滑动轨道502和第二滑动轨道503在与第一方向相垂直的截面上的形状是弧形的。
圆弧状的设计不仅满足同时在第一方向和轴线方向上都存在运动分量，并且容易加工，还可以使得滑动过程中的摩擦力更小。
在一些实施例中，主轴部531包括沿第三方向相对设置的第一盖板5315和第二盖板5316，第一盖板5315和第二盖板5316之间形成容纳空间，容纳空间包括第一滑动轨道502和第二滑动轨道50。如图11所示，主轴部531包括第一盖板5315和第二盖板5316，并且第一盖板5315和第二盖板5316沿第三方向相对设置，且存在两个关于主轴部531的轴线对称的容纳空间。在一种可能的实现方式中，第一盖板5315朝向第二盖板5316的一面为凹面，而第二盖板5316朝向第一盖板5315的一面为凹面，该凹面和该凸面在第三方向的距离等于两个滑动组件的厚度，厚度可以理解为其在第三方向的长度。
通过主轴部531内两个相对设置的盖板形成第一滑动轨道5311，有利于利用主轴部531内的空间，并且通过两个盖板装配到一起以形成轨道，可以便于加工组装。
在一些实施例中，同步连接机构50还包括止位组件537。
结合图12和图13对止位组件进行说明。
如图12所示，止位组件537包括弹性元件5371和滑动件5372，移动件5372和弹性元件5871沿第一方向设置，且移动件5372位于旋转件532与弹性元件5371之间；移动件5372在第一方向上的一端与旋转件532抵接，移动件5372在第一方向上的另一端与弹性元件5371在第一方向上的一端抵接，弹性元件5871在第一方向的另一端相对于移动件5372固定。
如上文所述，旋转件532可以绕第一轴线旋转，当其旋转时，其在第一方向上可产生运动分量，旋转件532的旋转可以使得与其面接触的滑动件5372在第一方向上运动，从而使得弹性元件5371在第一方向上产生弹性力，该弹性力通过滑动件5372传递给旋转件532，最终传递至第一滑动组件51和第二滑动组件52。该弹性力可以作为两个壳体转动的阻尼力、驱动力或者保持力。例如，当旋转件532的旋转可以使得与其面接触的滑动件5372沿第一方向的正方向运动，也即弹性元件被压紧，可以实现阻尼力，当旋转件532的旋转可以使得与其面接触的滑动件5372沿第一方向的负方向运动，也即弹性元件被松开，可以实现驱动力。
在一种可能的实现方式中，止位组件537的数量为两个，两个止位组件537分别设置在旋转件532在第一方向的两侧。
在一些实施例中，移动件5372设有通孔53721，主轴部531设有固定件，固定件设置于通孔53721内。如图12所示，在一种可能的实现方式中，该固定件为主轴部531的一部分。
图13示出了三种状态下，移动件5372与旋转件532之间的相对关系，a对应折叠状态，b对应中间状态，c对应展开状态。
在一些实施例中，移动件5372与旋转件532相抵接的一端包括第一子表面53721和第二子表面53722，第一子表面53721靠近第一滑动组件51，第二子表面53722靠近第二滑动组件52；旋转件532与移动件5372相抵接的一端包括第一表面5321和第二表面5322，第一表面5321靠近第一滑动组件51，第二表面5322靠近第二滑动组件52；第一子表面53721用于与第二表面5322抵接，使得第一滑动组件51和第二滑动组件52处于折叠状态时锁紧，和/或，第二子表面53722用于与第一表面5321抵接，使得第一滑动组件51和第二滑动组件52处于展开状态时锁紧。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
