为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例提供的铰链能够应用在可折叠的显示装置中，在不同的使用需求条件下，用户可以对可折叠的显示装置进行折叠或展开来满足用户不同的需求。示例的，当用户需要随身携带可折叠显示装置时，可以对其进行折叠，以降低其体积，从而提升便携性；当用户在使用可折叠显示装置时，可以将其展开，以提供更大的显示区域和操作区域，从而提升使用便利性。在实际应用中，可折叠显示装置的类型可以分为多种，例如其可以为手机、平板电脑、笔记本电脑、电子书等。
以手机为例，手机中可以包括通过铰链进行连接的第一壳体和第二壳体，在铰链的作用下，第一壳体和第二壳体之间能够产生相对转动。柔性屏幕可以设置在第一壳体和第二壳体的表面，当手机被展开时，柔性屏幕可以提供较大的显示面积和操作区域，以提升使用性能。当手机被折叠后，柔性屏幕可以被包裹在第一壳体、铰链和第二壳体之间，以对柔性屏幕提供良好的保护作用，防止外力作用下使柔性屏幕受到损坏，以提升手机的安全性能。以下实施例将对可折叠的显示装置中的铰链的结构进行详细的说明。
请参考图1和图2，图1是本申请实施例提供的一种铰链的结构示意图，图2是图1示出的铰链的爆炸图。该铰链可以包括：支撑座100和至少一组翻转组件。一组翻转组件可以包含关于该支撑座100对称设置的第一翻转组件200和第二翻转组件300。该第一翻转组件200和第二翻转组件300能够相对于支撑座100相向转动或者相背离转动，以实现铰链的折叠或展开功能。
铰链中的第一翻转组件200可以包括：第一摆臂201和第一翻转板202。第一摆臂201的第一端可以与支撑座100转动连接，第一摆臂201的第二端可以与第一翻转板202的背面转动连接。铰链中的第二翻转组件300可以包括：第二摆臂301和第二翻转板302。第二摆臂301的第一端可以与支撑座100转动连接，第二摆臂301的第二端可以与第二翻转板302的背面转动连接。
其中，请参考图3，图3是本申请实施例提供的一种铰链在展开状态和折叠状态之间切换的效果图。在铰链处于展开状态时，第一翻转组件200中的第一翻转板202的正面可以与第二翻转板302的正面共面；在铰链处于折叠状态时，第一翻转组件200中的第一翻转板202的正面可以与第二翻转板302的正面相对且平行。在铰链进行展开状态与折叠状态的切换过程中，第一翻转板202通过第一摆臂201绕铰链中的支撑座100转动，且第一翻转板202能够绕第一摆臂201的第二端摆动；第二翻转板302通过第二摆臂301绕支撑座100转动，且第二翻转板302能够绕第二摆臂301的第二端摆动。在本申请中，第一翻转板202绕第一摆臂201的第二端摆动的最大角度的范围为6度至13度，第二翻转板302绕第二摆臂301的第二端摆动的最大角度的范围也为6度至13度。
示例的，当铰链由展开状态切换到折叠状态时，在外力的作用下，第一翻转板202整体绕逆时针方向旋转，此时，第一翻转板202会带动第一摆臂201绕逆时针方向旋转。在旋转的过程中，第一翻转板202能够绕第一摆臂201的第二端摆动，使得第一翻转板202的背面与第一摆臂201的长度方向之间的夹角产生变化。在本申请中，请参考图4，图4是本申请实施例提供的第一翻转板的背面与第一摆臂的长度方向之间的夹角产生变化的原理图。在图4中，曲线L2代表相关技术中铰链的边缘的运动轨迹，其轨迹线为圆弧形轨迹。由于本申请中的铰链在旋转至任意位置时，第一翻转板202与第一摆臂201之间相对摆动的角度为δ，也即是，本申请中的铰链的边缘运动轨迹为非圆弧形的曲线L1。因此，铰链由展开状态切换到折叠状态时，第一翻转板202的背面与第一摆臂201之间的夹角逐渐减小，即展开状态时第一翻转板202的背面与第一摆臂201之间的夹角θ0的值大于折叠状态时第一翻转板202的背面与第一摆臂201之间的夹角θi的值，使得第一翻转板202和第一摆臂201构成的连杆机构能够伸展。如此，在折叠的过程中，铰链基本不会对显示装置中的柔性屏幕产生挤压，降低了柔性屏幕多次折叠后铰链对柔性屏幕产生损伤的概率。另外，由于铰链处于折叠状态时，第一翻转组件200中的第一翻转板202的正面可以与第二翻转板302的正面相对且平行。因此，在处于折叠状态时，第一翻转板202和第二翻转板302也不会对柔性屏幕压缩。在这种情况下，该铰链呈“U型”状，也称为U型铰链。
当铰链由折叠状态切换到展开状态时，在外力的作用下，第一翻转板202 整体绕顺时针方向旋转，此时，第一翻转板202也会带动第一摆臂201向顺时针方向旋转。在旋转的过程中，第一翻转板202能够绕第一摆臂201的第二端摆动，使得第一翻转板202的背面与第一摆臂201的长度方向之间的夹角产生变化。在本申请中，铰链由折叠状态切换到展开状态时，第一翻转板202的背面与第一摆臂201之间的夹角逐渐增大，即折叠状态时第一翻转板202的背面与第一摆臂201之间的夹角θi的值小于展开状态时第一翻转板202的背面与第一摆臂201之间的夹角θ0的值，使得第一翻转板202和第一摆臂201构成的连杆机构的长度能够缩短。如此，在展开的过程中，铰链基本不会对显示装置中的柔性屏幕产生拉扯，降低了柔性屏幕在多次展开后铰链对柔性屏幕产生损伤的概率。另外，由于铰链展开到最终状态时(即第一翻转板202和第二翻转板302之间的夹角为180度)，第一翻转组件200中的第一翻转板202的正面可以与第二翻转板302的正面共面，即第一翻转板202和第二翻转板302能够形成平整的支撑面。因此，能够对柔性屏幕提供良好的支撑作用。
需要说明的是，第一翻转组件200和第二翻转组件300可以相对于支撑座100对称设置，第二翻转组件300的基本结构组成和运动原理可以与第一翻转组件200相同。故在本申请实施例中，第二翻转组件300的结构组成和运动原理可参照上述对于第一翻转组件200的描述，在此不作赘述。
综上所述，本申请实施例提供了一种铰链，包括：支撑座和至少一组翻转组件，一组翻转组件包含关于支撑座对称设置的第一翻转组件和第二翻转组件。当铰链在展开状态与折叠状态之间切换时，在旋转的过程中，由于第一翻转板能够绕第一摆臂的第二端摆动，使得第一翻转板的背面与第一摆臂之间的夹角产生变化，而第一翻转板和第一摆臂构成的连杆机构的长度可以随着第一翻转板的背面与第一摆臂之间的夹角变化而伸长或缩短。因此，在显示装置的柔性屏幕折叠的过程中，铰链基本不会对柔性屏幕产生挤压或拉扯，进而降低了铰链对柔性屏幕产生损伤的概率，有效的提高了柔性屏幕的使用寿命。
下面将对第一翻转组件200中各组成部件之间的连接结构以及与支撑座100之间的连接结构作和运动原理具体说明；第二翻转组件300中各组成部件之间的连接结构及运动原理可参照对于第一翻转组件200的描述。

在本申请实施例中，如图6所示，第一摆臂201和支撑座100以及第二摆臂301和支撑座100之间实现转动连接的方式可以为虚拟轴式。示例的，铰链中的支撑座100可以包括：第一支座101，第一支座101可以具有第一弧形滑槽101a和第二弧形滑槽101b。第一翻转组件200中的第一摆臂201的第一端可以具有第一弧形导轨2012，第一弧形导轨2012可以位于第一弧形滑槽101a内，且与第一支座101转动连接。第二翻转组件300中的第二摆臂301的第一端可以具有第二弧形导轨3012，第二弧形导轨3012可以位于第二弧形滑槽101b内，且与第一支座101转动连接。在这种情况下，将第一弧形导轨2012装配在第一弧形滑槽101a内，便可实现第一摆臂201与支撑座100中的第一支座101之间的转动连接；将第二弧形导轨3012装配在第二弧形滑槽101b内，便可实现第二摆臂301与支撑座100中的第一支座101之间的转动连接。另外，通过虚拟轴式的连接方式，可以对第一弧形导轨2012和第二弧形导轨3012进行良好的隐藏，防止外露，从而能够增加铰链观感上的整体性。需要说明的是，在其他可能的实现方式中，第一摆臂201和第一支座101之间以及第二摆臂301与第一支座101之间也可以采用销轴或者其他的方式实现转动连接，本申请实施例对此不作具体的限定。
可选的，如图6所示，铰链中的一组翻转组件还可以包含压板400，压板400可以与第一支座101中设置第一弧形滑槽101a和第二弧形滑槽101b的一侧固定连接。其中，在铰链处于展开状态时，压板400背离第一支座101的一面与第一翻转板202的正面和第二翻转板302的正面共面。在这种情况下，通过压板400能够将第一弧形导轨2012限位在第一弧形滑槽101a内，第二弧形导 轨3012限位在第二弧形滑槽101b内，实现第一弧形导轨2012与第一弧形滑槽101a以及第二弧形导轨3012与第二弧形滑槽101b的稳定连接。另外，在铰链展开至最终状态时，第一翻转板202、压板400和第二翻转板302能够形成平整的支撑面。如此，能够对显示装置中的柔性屏幕提供良好的支撑作用。
为了保证铰链在折叠或展开过程中，一组翻转组件中的第一翻转组件200和第二翻转组件300能够同步动作，本申请提供了一种同步组件能够实现第一翻转组件200和第二翻转组件300之间的同步相向转动和同步背离转动。请参考图7和图8，图7是本申请实施例提供的又一种铰链的结构示意图，图8是图7示出的铰链的局部爆炸图。该铰链还可以包括：至少一组同步组件，一组同步组件可以包含关于支撑座100对称设置的第一同步组件500和第二同步组件600。该第一同步组件500可以与第一翻转组件200连接，第二同步组件600可以与第二翻转组件300连接，且第一同步组件500可以与第二同步组件600连接。其中，第一同步组件500和第二同步组件600可以被配置为：带动第一翻转组件200和第二翻转组件300同步转动。在这种情况下，通过第一同步组件500与第一翻转组件200的连接，以及第二同步组件600与第二翻转组件300的连接，能够实现第一翻转组件200与第二翻转组件300的同步转动，提升了用户的使用体验感。

示例的，当外力作用在第一翻转板202上时，第一翻转板202整体向逆时针方向旋转时，第一翻转板202也带动第一连杆501逆时针转动。然后，第一连杆501带动第一主动同步轴502逆时针转动，第一主动同步轴502带动第一 主动齿轮503逆时针转动。之后，第一主动齿轮503带动第二主动齿轮603顺时针转动，第二主动齿轮603带动第二主动同步轴602顺时针转动。之后，第二主动同步轴602带动第二连杆601顺时针转动。最后，第二连杆601带动第二翻转板302也顺时针转动，第二翻转板302同时带动第二摆臂301顺时针转动。如此，能够通过第一同步组件500和第二同步组件600实现第一翻转组件200和第二翻转组件300的同步转动。

在实际应用中，当铰链在折叠或展开过程中，为了使其具备一定的阻尼效果或自悬停能力，在本申请实施例中，铰链还可以包括：至少一组扭力组件，至少一组扭力组件可以与至少一组同步组件一一对应。请参考图9和图10，图9是本申请实施例提供的再一种铰链的结构示意图，图10是图9示出的铰链的局部爆炸图。至少一组扭力组件中的一组扭力组件可以包括：分别与对应的一组同步组件中的第一主动同步轴502和第二主动同步轴602连接的第一扭力组件700和第二扭力组件800。其中，第一扭力组件700和第二扭力组件800可以被配置为：在第一翻转组件200和第二翻转组件300转动时，提供阻尼力。

一组扭力组件中的第二扭力组件800可以位于第二主动齿轮603背离第二连杆601的一侧。第二扭力组件800可以包括：套接在第二主动同步轴602上的第二动凸轮801，第二定凸轮802、第二弹性元件803和第二锁定件804。第二动凸轮801可以与第二主动同步轴602固定连接，第二定凸轮802可以位于第二动凸轮801背离第二主动齿轮603的一侧，且可以与第二主动同步轴602转动连接。第二锁定件804可以位于第二定凸轮802背离第二动凸轮801的一侧，且可以与第二主动同步轴602固定连接。第二弹性元件803可以位于第二定凸轮802与第二锁定件803之间。其中，第一定凸轮702可以与第二定凸轮802固定连接。示例的，当第一连杆501转动时，第一连杆501带动第一主动同步轴502转动。然后，第二主动同步轴502带动第一动凸轮701可以相对第一定凸轮702转动，当第一动凸轮701的凸出部趋于滑出第一定凸轮702的凹陷部时，第一弹性元件703被压缩。如此，通过第一扭力组件700能够提供一定 的阻尼力。当第一动凸轮701的凸出部位于第一定凸轮702的凹陷部时，通过第一弹性元件703使得第一定凸轮702和第一动凸轮701能够保持相对静止。如此，通过第一扭力组件700能够实现显示装置的自悬停效果。
例如，当铰链处于完全展开状态时，第一定凸轮702的凸出部(图中未示出)可以恰好位于第一动凸轮701的凹陷部(图中未示出)内，以使铰链能够保持该特定角度，当用户在触摸或按压柔性屏幕时，在外力作用下显示装置不会被轻易折叠。当铰链处于完全折叠状态时，第一定凸轮702的凸出部可以恰好位于第一动凸轮701的凹陷部内，以使铰链能够保持该特定角度。当用户在触摸或按压柔性屏幕时，在外力作用下显示装置不会被随意展开，从而能够保证显示装置的安全性。需要说明的是，第二扭力组件800的运动原理可参照上述对于第一扭力组件700的相关描述，在此不作赘述。
可选的，第一弹性元件703和第二弹性元件803均可以包括：层叠设置的多个碟簧。需要说明的是，在其他可能的实现方式中，第一弹性元件703和第二弹性元件803还可以为压缩弹簧或者弹片，本申请实施例对此不作具体的限定。

可选的，铰链中的翻转组件的组数可以为两组，两组翻转组件可以沿第三支座103的长度方向排布。在本申请中，两组翻转组件之间还可以设置支撑板900，通过支撑板900能够对显示装置中的柔性屏幕的中央区域起到支撑的作用。
综上所述，本申请实施例提供了一种铰链，包括：支撑座和至少一组翻转组件，一组翻转组件包含关于支撑座对称设置的第一翻转组件和第二翻转组件。当铰链在展开状态与折叠状态之间切换时，在旋转的过程中，由于第一翻转板能够绕第一摆臂的第二端摆动，导致第一翻转板的背面与第一摆臂之间的夹角产生变化，而第一翻转板和第一摆臂构成的连杆机构的长度可以随着第一翻转板的背面与第一摆臂之间的夹角变化而伸长或缩短。因此，在显示装置的柔性 屏幕折叠的过程中，铰链基本不会对柔性屏幕产生挤压或拉扯，进而降低了铰链对柔性屏幕产生损伤的概率，有效的提高了柔性屏幕的使用寿命。
在实际应用中，本申请中给出的铰链可以应用在多种需要通过铰链实现折叠或展开功能的显示装置中。示例的，本申请实施例还提供了一种显示装置，请参考图12，图12是本申请实施例提供的显示装置的部分结构示意图。该显示装置可以包括：机壳(图中未示出)、柔性屏幕01和铰链。铰链可以安装在机壳内，柔性屏幕01的边缘可以与机壳的边缘连接，柔性屏幕01的背面可以与铰链中的第一翻转板202的正面和第二翻转板302的正面贴合。
在本申请中，机壳可以包括第一壳体和第二壳体，第一翻转板202可以与第一壳体固定连接，第二翻转板302可以与第二壳体固定连接，如此，第一壳体和第二壳体之间通过铰链实现转动连接。在实际应用中，第一壳体和第二壳体内可以设置处理器、电池和摄像头等器件。示例的，第一壳体可以通过螺钉连接、焊接或粘接等方式与第一翻转板202固定连接，第二壳体也可以通过螺钉连接、焊接或粘接的方式与第二翻转板302固定连接。显示装置中的柔性屏幕01的一部分可以与第一壳体粘接，另一部分可以与第二壳体粘接，以实现机壳对柔性屏幕01的支撑。
本申请分别对采用相关技术中的铰链对柔性屏幕进行折叠以及采用本申请实施例给出的铰链对柔性屏幕进行折叠，柔性屏幕在转动过程中所受的应力进行仿真分析。示例的，通过对柔性屏幕中的无机层在折叠过程中所受的应力进行仿真分析，可得到图13所示的结果。图13是柔性屏幕中的无机层在折叠过程中的受力分析示意图。曲线A代表采用相关技术中的铰链对柔性屏幕进行折叠时，无机层所受的应力随转动时间的动态值；曲线B代表采用本申请实施例中的铰链对柔性屏幕进行折叠时，无机层所受的应力随转动时间的动态值。从图13中可以看出，采用相关技术中的铰链对柔性屏幕进行折叠时，无机层所受的应力最大值约为0.0027，而采用本申请实施例给出的铰链对柔性屏幕进行折叠时，无机层所受的应力最大值约为0.0005。
通过对柔性屏幕中的胶层在折叠过程中所受的应力进行仿真分析，可得到图14所示的结果。图14是柔性屏幕中的胶层在折叠过程中的受力分析示意图。曲线C代表采用相关技术中的铰链对柔性屏幕进行折叠时，该柔性屏幕中的胶 层所受的应力随转动时间的动态值；曲线D代表采用本申请中的铰链对柔性屏幕进行折叠时，胶层所受的应力随转动时间的动态值。从图14中可以看出，采用相关技术中的铰链对柔性屏幕进行折叠时，胶层所受的应力最大值约为1.3，而采用本申请实施例给出的铰链对柔性屏幕进行折叠时，胶层所受的应力最大值也约为1.3。由上可知，采用本申请中的铰链对柔性屏幕进行折叠时，柔性屏幕中的无机层的应力能够得到有效的降低，进而降低了铰链对柔性屏幕路产生损伤的概率，有效的提高了柔性屏幕的使用寿命。
