因所述OLED面板具备可柔性、可穿戴等优点，故所述柔性显示面板主体200能够随着所述铰链100进行弯曲、折叠、卷曲，进而实现所述柔性显示面板1000的可弯曲、可折叠、可卷曲，当然地要实现所述柔性显示面板1000的可卷曲需使所述铰链100的整体长度与所述柔性显示面板主体200配合。本申请实施例以所述柔性显示面板1000可折叠为例说明。
所述柔性显示面板1000具有折叠区BD，所述铰链100对应所述折叠区BD设置，且所述铰链100固定在所述柔性显示面板1000的壳体300上，并与所述壳体300一块承载所述柔性显示面板主体200。当所述柔性显示面板1000用于手机等电子装置时，所述壳体300可以为手机的中框。
下面将具体阐述本申请中所述铰链100的结构以及工作原理：
请结合参照图1至图9，图4为本申请实施例提供的铰链的整体结构示意图，图5为本申请实施例提供的铰链折叠后支撑构件的排布示意图，图6和图7为本申请实施例提供的铰链处于第一位置时第一封装机构的两种截面示意图，图8和图9为本申请实施例提供的铰链处于第二位置时第一封装机构的两种截面示意图。所述铰链100包括依次转动连接的多个支撑构件（如图4示出的第一支撑构件11、第二支撑构件12、第三支撑构件13、第四支撑构件14）、多个转动机构20、联动机构30以及第一封装机构40。多个所述转动机构20设置于多个所述支撑构件的一侧，每一所述转动机构20连接于相邻的两所述支撑构件（如图4示出的相邻的第一支撑构件11和第二支撑构件12），用于使相邻的两个所述支撑构件发生相对转动。
所述联动机构30设置于多个所述支撑构件的所述一侧，也即所述联动机构30与所述转动机构20设置于多个所述支撑构件的同一侧，所述联动机构30连接于相间的两所述支撑构件（如图4示出的相间的第二支撑构件12和第四支撑构件14），以使相间的两所述支撑构件同步转动，相间的两所述支撑构件之间设置有至少一所述支撑构件（如图4示出的相间的第二支撑构件12和第四支撑构件14之间设置有第三支撑构件13）。相间的两所述支撑构件是指彼此不相邻的两个支撑构件，该不相邻的两个支撑构件之间还设置有其他支撑构件。
所述第一封装机构40面向多个所述转动机构20设置，且多个所述转动机构20位于所述第一封装机构40和多个所述支撑构件的一侧。所述第一封装机构40包括至少一第一背板41和至少一第二背板42，所述第一背板41可活动地连接于所述第二背板42，且所述第一背板41和所述第二背板42分别连接于相间的两所述支撑构件（如图8示出的相间的第一支撑构件11和第四支撑构件14），相间的两所述支撑构件之间设置有至少一所述支撑构件（如图8示出的相间的第一支撑构件11和第四支撑构件14之间设置有第二支撑构件12和第三支撑构件13）。
其中，所述柔性显示面板主体200位于多个所述支撑构件的远离所述转动机构20和所述联动机构30的另一侧，也即所述柔性显示面板主体200位于所述支撑构件远离所述转动机构20和所述联动机构30的一侧。
当多个所述支撑构件处于第一位置时，所述柔性显示面板主体200处于平坦状态，多个所述支撑构件水平排布并支撑所述柔性显示面板主体200，且多个所述支撑构件水平排布可形成平整的表面，以给所述柔性显示面板主体200提供平整的承载表面。此时所述第一封装机构40展平，使所述第一背板41和所述第二背板42之间形成第一夹角，第一夹角为180度，也即所述第一背板41和所述第二背板42水平设置，以遮挡所述转动机构20和所述联动机构30，避免灰尘等异物进入所述铰链。
当多个所述支撑构件处于第二位置时，所述柔性显示面板主体200处于弯曲状态，位于两端部的多个所述支撑构件在位于中部的多个支撑构件的同一侧并相对设置，使得多个所述支撑构件呈U型排布，所述柔性显示面板主体200与所述支撑构件形成的U型结构的U型外表面贴合。此时所述第一背板41和所述第二背板42之间形成第二夹角a，以遮挡所述转动机构20和联动机构30，其中所述第二夹角a小于所述第一夹角，使所述第一封装机构40隐藏在所述U型开口内。
需要说明的是，请结合参照图4和图5，位于两端部的多个所述支撑构件是指转动连接的多个支撑构件中，位于相对两边的支撑构件，如图4和图5中示出的第一支撑构件11和第四支撑构件14即为位于两端部的支撑构件。位于中部的多个支撑构件是指位于两端部的多个支撑构件之间的支撑构件，如图4和图5中示出的第二支撑构件12和第三支撑构件13位于第一支撑构件11和第四支撑构件14之间，则第二支撑构件12和第三支撑构件13即为位于中部的支撑构件。当多个所述支撑构件处于第二位置时，第一支撑构件11和第四支撑构件14位于第二支撑构件12和第三支撑构件13的同一侧，且第一支撑构件11和第四支撑构件14相对设置。
另外，本申请的第二位置是指所述柔性显示面板1000处于折叠状态时多个所述支撑构件运动到的位置，第一位置是指所述柔性显示面板1000处于展平状态时多个所述支撑构件运动到的位置。当多个所述支撑构件运动到所述第二位置时，每相邻的两个所述支撑构件之间的夹角均大于90度，使多个所述支撑构件整体形成圆滑的U型结构，所述柔性显示面板主体200与U型结构外表面贴合，由于U型结构拐角处是圆滑的过渡面，如此在实现所述柔性显示面板1000的外折叠的同时，使得所述柔性显示面板主体200在弯折过程中不会受到较大拉扯且有机构支撑。如此在所述柔性显示面板1000折叠前后所述柔性显示面板主体200和所述铰链100的机构表面始终贴合在一块，实现了所述铰链100的机构表面与柔性显示面板主体200的尺寸始终相匹配。

可选地，所述联动机构30的数量至少为2，以保证相间的两所述支撑构件以及相间的两所述支撑构件之间的支撑构件联动的稳定性，但本申请不限于此，本申请的所述联动机构30的具体数量可根据所述支撑构件的长度以及所述支撑构件上的空间布局来确定。
请参照图4至图20，图17为图4中第二封装机构的放大示意图，图18为图17中第二封装机构的细节示意图，图19为本申请实施例提供的第二封装机构在折叠状态的一种示意图，图20为图4中第一封装机构的细节图。所述第一封装机构40包括至少一第一背板41和至少一第二背板42，所述第一背板41可活动地连接于所述第二背板42，且所述第一背板41和所述第二背板42分别连接于相间的两所述支撑构件，且所述第一背板41和所述第二背板42的转动轴线重合，如此所述第一背板41和所述第二背板42能够相对于支撑构件转动。
具体地，所述铰链100还包括第二封装机构50，所述第二封装机构50设置于多个所述支撑构件的端部，所述第二封装机构50包括多个封装构件，每个所述封装构件与对应的所述支撑构件固定连接，则所述第二封装机构50能够随着所述支撑构件的转动而转动，且所述第二封装机构50能够从所述铰链100的侧面对所述铰链100的内部机构件进行保护，并与所述第一封装机构40配合对所述铰链100形成有效保护，使得所述铰链100在折叠前后都不会有内部机构件裸露。

可以理解的是，当所述第一封装构件51和所述第三封装构件53之间设置有两个或更多个第二封装构件52时，多个第二封装构件52之间也滑动连接，此时相邻的两个第二封装构件52中的一个第二封装构件52的第一弧形凸起521可滑动地安装于另一个第二封装构件52的第二弧形凹槽522内。
所述第一背板41和所述第二背板42分别可滑动地连接于所述相间的两所述支撑构件的端部的所述封装构件。也即所述第一背板41和所述第二背板42分别与对应的封装构件滑动连接，而所述封装构件又分别与对应的支撑构件连接，从而使得所述第一背板41和所述第二背板42间接地与对应的支撑构件滑动连接，进而使所述支撑构件的转动带动对应的封装构件转动，而封装构件的转动能够带动所述第一背板41和所述第二背板42的转动，以实现所述第一背板41和所述第二背板42遮挡转动机构20和联动机构30的目的。

请继续参照图4至图19，本申请实施例以所述支撑构件的数量为4为例对所述铰链100的结构和工作原理做进一步说明。多个所述支撑构件包括第一支撑构件11、第二支撑构件12、第三支撑构件13、第四支撑构件14。相邻的所述第一支撑构件11和所述第二支撑构件12之间、相邻的所述第二支撑构件12和所述第三支撑构件13之间、相邻的所述第三支撑构件13和所述第四支撑构件14之间均设置有所述转动机构20。相间的所述第一支撑构件11和所述第三支撑构件13以及相间的所述第二支撑构件12和所述第四支撑构件14之间均设置有联动机构30。其中，相间的所述第一支撑构件11和所述第三支撑构件13之间设置有所述第二支撑构件12，相间的所述第二支撑构件12和所述第四支撑构件14之间设置有所述第三支撑构件13。

所述第二支撑构件12和所述第三支撑构件13之间以及所述第三支撑构件13和所述第四支撑构件14之间设置的转动机构20的结构及工作原理可参照对所述第一支撑构件11和所述第二支撑构件12之间的转动机构20的描述，在此不再赘述。
可选地，各相邻的所述支撑构件之间的转动机构20交错设置，比如所述第一支撑构件11和第二支撑构件12之间的转动机构20的各转动件与第三支撑构件13和第四支撑构件14之间的转动机构20的各转动件交错设置，以避免各转动机构20之间发生干涉，并合理利用所述支撑构件上的有限空间。
进一步地，以相间的第二支撑构件12和第四支撑构件14之间的联动机构30为例说明。所述联动机构30包括联动组件31、连接组件32以及同步组件33。所述联动组件31与所述第三支撑构件13活动连接，所述连接组件32分别与所述第二支撑构件12和所述第四支撑构件14固定连接，并与所述联动组件31滑动连接。所述同步组件33与所述第三支撑构件13固定连接，所述联动组件31与所述同步组件33活动连接。其中所述的固定连接方式包括通过销钉、粘接、焊接、螺钉等方式进行固定连接。

所述连接组件32包括第一连接件321和第二连接件322，所述第一连接件321设置有第一滑动槽3211，所述第二连接件322设置有第二滑动槽3221。所述第一圆柱轴3111可滑动地安装于所述第一滑动槽3211内，所述第二圆柱轴3121可滑动地安装于所述第二滑动槽3221内，以使所述第一圆柱轴3111能够在所述第一滑动槽3211中滑动和转动，所述第二圆柱轴3121能够在所述第二滑动槽3221中滑动和转动。同时由于所述第一齿轮和所述第二齿轮的互相啮合且能够相对所述第三支撑构件13转动，如此可使得所述第二支撑构件12、所述第三支撑构件13以及所述第四支撑构件14之间同步联动，且所述第二支撑构件12和所述第四支撑构件14相对于所述第三支撑构件13始终保持对称旋转运动。
可选地，所述第一连接件321和所述第二连接件322上还可设置限位构件（图未示），所述限位构件位于所述第一滑动槽3211和所述第二滑动槽3221的两端，且与所述第一连接件321和所述第二连接件322一体成型，当然地，本申请不限于此，本申请的限位构件还可单独设置。所述限位构件用于限制所述第一圆柱轴3111和所述第二圆柱轴3121在对应的滑动槽内的滑动距离，以定位相邻的两个所述支撑构件的转动角度。
相对应地，相间的所述第一支撑构件11和所述第三支撑构件13之间的联动机构30的结构及联动原理，与相间的所述第二支撑构件12和所述第四支撑构件14之间的联动机构30结构及联动原理相同，可使得所述第二支撑构件12、所述第三支撑构件13以及所述第一支撑构件11之间联动，且所述第一支撑构件11和所述第三支撑构件13相对于所述第二支撑构件12始终保持对称旋转运动。
可选地，多个所述联动机构30之间交错设置，以避免多个所述联动机构30之间发生干涉，并合理利用所述支撑构件上的有限空间。
进而通过所述转动机构20和所述联动机构30的动作，当所述第一支撑构件11相对所述第二支撑构件12转动时，所述第一支撑构件11与所述第三支撑构件13之间也会产生相对滑动，并通过滑动配合推动所述第三支撑构件13相对所述第二支撑构件12转动；相应地，当所述第四支撑构件14相对所述第三支撑构件13转动时，所述第四支撑构件14与所述第二支撑构件12之间也会产生相对滑动，并通过滑动配合推动所述第二支撑构件12相对所述第三支撑构件13转动。因此，在此过程中所述铰链100中的所述第一支撑构件11、所述第二支撑构件12、所述第三支撑构件13和所述第四支撑构件14可同步动作。
故当所述第一支撑构件11、所述第二支撑构件12、所述第三支撑构件13、所述第四支撑构件14运动到所述第二位置时，相邻两个支撑构件之间的夹角可以相等，且所述夹角均大于90度。此时所述第一支撑构件11、所述第二支撑构件12、所述第三支撑构件13、所述第四支撑构件14排布成U型，其中所述第一支撑构件11和所述第四支撑构件14相对设置。
而且当所述第一支撑构件11、所述第二支撑构件12、所述第三支撑构件13、所述第四支撑构件14运动到所述第一位置时，相邻两个支撑构件之间的夹角仍然相等，所述夹角均为180度。此时所述第一支撑构件11、所述第二支撑构件12、所述第三支撑构件13、所述第四支撑构件14整体呈水平排布，为所述柔性显示面板主体200提供平整的承载表面。
下面接着阐述所述第一封装机构40和第二封装机构50的结构：
所述第一封装机构40与所述第一旋转固定构件60活动连接，所述第一旋转固定构件60与所述第二支撑构件12或所述第三支撑构件13固定连接，本实施例以所述第一旋转固定构件60与所述第二支撑构件12固定连接为例说明，所述第一背板41和所述第二背板42均与所述第一旋转固定构件60活动连接。
具体地，如图20所示，所述第一背板41和所述第二背板42上分别设置有第一轴孔412和第二轴孔422，所述第一旋转固定构件60上设置有第三轴孔61，所述第一轴孔412、所述第二轴孔422和所述第三轴孔61的轴心重合。所述第一轴孔412、所述第二轴孔422和所述第三轴孔61之间可通过一转轴62连接，形成轴孔配合，使所述第一背板41和所述第二背板42的转动轴线重合，且所述第一背板41和所述第二背板42均可相对所述第一旋转固定构件60转动。
参照图7，所述第一背板41和所述第二背板42还与所述第二封装机构50活动连接。所述第二封装机构50包括一个第一封装构件51、两个第二封装构件52和一个第三封装构件53，所述第一封装构件51与所述第一支撑构件11的端部固定连接，两个所述第二封装构件52分别与所述第二支撑构件12和所述第三支撑构件13的端部固定连接，所述第三封装构件53与所述第四支撑构件14的端部固定连接，以使得各所述支撑构件的同步转动带动所述第二封装机构50的转动。所述第二封装机构50的数量为2，分别位于各所述支撑构件相对两侧的端部。
具体地，所述第一封装构件51面向所述第一背板41的一侧设置有第一凸台512，所述第三封装构件53面向所述第二背板42的一侧设置有第二凸台532，所述第一凸台512和所述第二凸台532均可为直圆柱。所述第一背板41的相对两端的端部开设有第一直线槽411，所述第二背板42的相对两端的端部开设有第二直线槽421。所述第一凸台512可滑动地安装于所述第一直线槽411内，以使得所述第一背板41随着所述第一封装构件51的转动而相对所述第二支撑构件12转动。所述第二凸台532可滑动地安装于所述第二直线槽421内，以使得所述第二背板42随着所述第三封装构件53的转动而相对所述第二支撑构件12转动。
如此在所述第一支撑构件11、所述第二支撑构件12、所述第三支撑构件13、所述第四支撑构件14运动到所述第二位置时，所述第二封装机构50的多个所述封装构件彼此旋转转动，使与第一封装构件51相邻的第二封装构件52的第一弧形凸起521隐藏到第一弧形凹槽511内，与第三封装构件53相邻的第二封装构件52的第一弧形凸起521隐藏到与第一封装构件51相邻的第二封装构件52的第二弧形凹槽522内，而第三封装构件53的第二弧形凸起531隐藏到与其相邻的第二封装构件52的第二弧形凹槽522内，形成如图19所示的折叠状态。所述第一封装机构40的第一背板41和第二背板42随着所述第二封装机构50的转动而相对所述第二支撑构件12转动，使第一背板41和第二背板42之间呈第二夹角设置，隐藏到多个支撑构件形成的U型结构内。
在所述第一支撑构件11、所述第二支撑构件12、所述第三支撑构件13、所述第四支撑构件14运动到第一位置时，所述第二封装机构50的多个所述封装构件彼此旋转转动，使封装构件的弧形凸起从相邻的封装构件的弧形凹槽内旋出，如第三封装构件53的第二弧形凸起531从相邻的第二封装构件52的第二弧形凹槽522内旋出。所述第一封装机构40的第一背板41和第二背板42随着所述第二封装机构50的转动而相对所述第二支撑构件12转动，最终呈水平排布形成平整的表面。如此在所述柔性显示面板1000折叠前后，所述第一封装机构40和所述第二封装机构50均可有效地保护所述铰链100的内部构件，避免所述铰链100的内部构件裸露。
在一种实施例中，所述柔性显示面板1000还包括第一固定构件70，所述第一固定构件70连接于所述铰链100和所述壳体300。具体地，所述第一支撑构件11和所述第四支撑构件14分别通过所述第一固定构件70与对应的所述壳体300固定连接。
可选地，所述第一固定构件70还可与对应的支撑构件或壳体300一体成型，例如所述第一固定构件70与所述第一支撑构件11一体成型，然后所述第一固定构件70与所述壳体300固定连接，所述固定连接方式包括通过销钉、粘接、焊接、螺钉等方式进行固定连接。
在一种实施例中，请参照图21和图22，图21为本申请实施例提供的第一封装机构在展平状态的另一种截面结构示意图，图22为本申请实施例提供的第一封装机构在折叠状态的另一种截面结构示意图。与上述实施例不同的是，所述铰链100还包括第二旋转固定构件80，所述第二旋转固定构件80与所述第二支撑构件12或所述第三支撑构件13固定连接，所述第一背板41和所述第二背板42均与所述第二旋转固定构件80活动连接，且与所述第二旋转固定构件80连接的位置不同，如此仍可保证所述第一背板41和所述第二背板42的转动轴线重合，使所述第二旋转固定构件80达到与所述第一旋转固定构件60相同的效果，其他说明请参照上述实施例，在此不再赘述。
需要说明的是，本申请实施例仅以铰链100包括4个支撑构件为例说明，但本申请不限于此，本申请的铰链100还可设置更多的支撑构件，例如可设置为5个支撑构件、6个支撑构件等，当设置更多的支撑构件时，还可实现可卷曲的显示装置柔性显示面板1000。
另外，本申请所述铰链100的转动机构20和联动机构30不限于上述实施例示意的，本申请的所述铰链100通过所述转动机构20和所述联动机构30的动作能实现在第一位置形成平整支撑面，在第二位置形成U型表面即可。例如本申请的所述铰链100的转动机构20还可通过合页、连接杆、齿轮等结构件实现相邻两个支撑构件之间的转动。
在一种实施例中，本申请还提供一种电子装置，所述电子装置包括上述实施例其中之一的柔性显示面板，使所述电子装置可实现可折叠、可卷曲等，且使得所述电子装置在折叠或卷曲前后所述柔性显示面板的铰链机构表面与柔性显示面板主体的尺寸相匹配。所述电子装置可以为手机、平板等电子产品。
基于同一发明构思，本申请还提供一种铰链，所述铰链包括上述实施例中所述柔性显示面板上的铰链，在此不再赘述。
根据上述实施例可知：
本申请提供一种柔性显示面板、电子装置以及铰链，柔性显示面板包括铰链和柔性显示面板主体，所述铰链包括依次转动连接的多个支撑构件、转动机构、联动机构、第一封装机构以及第二封装机构；转动机构设置于多个所述支撑构件的一侧，每一所述转动机构连接于相邻的两所述支撑构件，用于使相邻的两个所述支撑构件发生相对转动；联动机构设置于多个所述支撑构件的所述一侧，所述联动机构连接于相间的两所述支撑构件，以使相间的两所述支撑构件同步转动，第一封装机构设置于所述转动机构远离多个所述支撑构件的一侧，包括至少一第一背板和至少一第二背板，所述第一背板可活动地连接于所述第二背板，且所述第一背板和所述第二背板分别连接于相间的两所述支撑构件，相间的两所述支撑构件之间设置有至少一所述支撑构件，所述第二封装机构设置于多个所述支撑构件的端部，所述第二封装机构包括多个封装构件，每个所述封装构件与对应的所述支撑构件固定连接；所述柔性显示面板主体位于多个所述支撑构件的远离所述转动机构和所述联动机构的一侧，多个支撑构件通过转动和联动运动到第一位置时，多个支撑构件水平排布，用于给所述柔性显示面板主体提供平整的承载表面共同支撑柔性显示面板主体，第一封装机构和第二封装机构均展平，第一背板和第二背板之间形成第一夹角，以遮挡所述转动机构和所述联动机构，所述第二封装就够保护所述铰链的侧面；当多个支撑构件运动到第二位置时，柔性显示面板主体处于弯曲状态，位于两端部的多个支撑构件在位于中部的多个支撑构件的同一侧并相对设置，使多个支撑构件呈U型排布，多个支撑构件形成U型表面，保持与柔性显示面板主体底部贴合，第一背板和第二背板之间形成第二夹角，以遮挡转动机构，第二夹角小于第一夹角，使第一封装机构隐藏在U型的开口内，如此使得柔性显示面板在折叠前后封装机构均可遮挡和保护铰链的内部机构件。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
