其中，所述柔性显示面板主体200位于多个所述支撑构件10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10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10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10水平排布形成并支撑所述柔性显示面板主体200，且多个所述支撑构件10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。
当多个所述支撑构件10运动到第二位置时，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10在位于中部的多个支撑构件10的同一侧并相对设置，使得多个所述支撑构件10呈U型排布，所述柔性显示面板主体200与所述支撑构件10形成的U型结构的U型外表面贴合。

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10以及相间的两所述支撑构件10之间的支撑构件10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10的长度以及所述支撑构件10上的空间布局来确定。
请继续参照图4至图12，本申请实施例以所述支撑构件10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10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。
具体地，以所述第一支撑构件11和所述第二支撑构件12之间设置的转动机构20为例说明。所述转动机构20包括第一转动件21和第二转动组件22，所述第二转动组件22包括第二转动件221和第三转动件222，所述第一转动件21固定在所述第一支撑构件11上，所述第二转动件221和所述第三转动件222固定在所述第二支撑构件12上，且所述第一转动件21可滑动地连接于所述第三转动件222以及所述第二转动件221。
可选地，所述第一转动件21上设置有第一弧形凸耳211和第一弧形滑槽212，所述第三转动件222上设置有第二弧形凸耳2221，所述第二转动件221设置有第二弧形滑槽2211，所述第一弧形凸耳211与所述第二弧形滑槽2211滑动配合，以使所述第一转动件21与所述第二转动件221可以相对滑动；所述第二弧形凸耳2221和所述第一弧形滑槽212滑动配合，以使所述第一转动件21与所述第三转动件222可以相对滑动。如此使得所述第一支撑构件11与所述第二支撑构件12之间能够相对旋转，旋转中心即为所述转动机构20上各弧形滑槽或弧形凸耳的弧形圆心。
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10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10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。
可选地，所述联动组件31包括第一联动件311和第二联动件312，所述第一联动件311包括第一齿轮，所述第二联动件312包括第二齿轮，所述第一齿轮和所述第二齿轮互相啮合，且可活动地连接于所述同步组件33，以使得所述第一联动件311和所述第二联动件312相对于所述第三支撑构件13能够同步转动。所述第一齿轮和所述第二齿轮在远离啮合处的一端分别设置有第一圆柱轴3111和第二圆柱轴3121。
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10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10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10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10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。
在一种实施例中，所述柔性显示面板1000还包括固定构件50，所述固定构件50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分别通过所述固定构件50与对应的所述壳体300固定连接。
可选地，所述固定构件50还可与对应的支撑构件10或壳体300一体成型，例如所述固定构件50与所述第一支撑构件11一体成型，然后所述固定构件50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。
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10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10，例如可设置为5个支撑构件10、6个支撑构件10等，当设置更多的支撑构件10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10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，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、转动机构以及联动机构；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；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的一侧，多个支撑构件通过转动和联动运动到第二位置时，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，并使柔性显示面板主体在弯折过程中不会受到较大拉扯且有机构支撑；多个支撑构件运动到第一位置时，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，解决了现有外折叠显示设备存在的折叠前显示装置机构表面与柔性屏尺寸不匹配的问题。
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。
以上对本申请实施例进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
