铰链、柔性显示面板及电子装置 技术领域
本申请涉及显示技术领域，尤其涉及一种铰链、柔性显示面板及电子装置。
 背景技术
随着显示技术的不断发展，为了满足不同的使用需求，各种具有不同特性的显示也应运而生。智能化、便携化、柔性化的发展趋势是当前电子装置的主要发展方向之一。柔性显示技术相对于传统的平板显示技术最突出的优势在于，突破了原有的二维显示的固有理念，将显示技术的应用领域拓展到更多的便携式的电子装置中。用户可以根据需要将具有柔性显示面板的电子装置进行折叠或者卷曲，以减小电子装置的尺寸，提高电子装置的便携性。
 技术问题
目前可折叠的电子装置通过铰链中相对设置的两个转动机构实现展开和闭合的效果。在电子装置折叠或展开的过程中，由于铰链中的两个转动机构的转动速度不能始终保持相同，使得电子装置无法实现双边同步旋转，导致电子装置的柔性显示面板主体被铰链挤压或拉扯，降低了电子装置的使用寿命。

需要说明的是，电子装置1000可以具有至少一条用于折叠电子装置1000的旋转轴线，下文中，第一方向x表示与旋转轴线垂直的方向，第二方向y表示与旋转轴线平行的方向，第三方向z表示电子装置1000的厚度方向，电子装置的显示表面可以由第一方向x和第二方向y限定。
柔性显示面板100还包括铰链2，铰链2包括第一铰链2a和第二铰链2b，第一铰链2a和第二铰链2b分别设置于第三壳体600上的相对端。第一铰链2a和第二铰链2b可以设置于第一壳体200和第二壳体300之间，第一铰链2a和第二铰链2b均与第一壳体200和第二壳体300连接，第一铰链2a和第二铰链2b可以配置成使第一壳体200和第二壳体300绕与第二方向y平行且在第一方向x上间隔开的两条旋转轴线旋转。
在本申请实施例中，第一铰链2a和第二铰链2b的结构相同，运动过程也相同。下文中，各示意图仅以第一铰链2a的结构为例进行说明，此处不再赘述。在实际应用中，第一铰链2a和第二铰链2b的结构也可以不同，但必须满足第一铰链2a和第二铰链2b能够使第一壳体200和第二壳体300同步旋转。
需要说明的是，下文中，平坦状态可以指电子装置1000完全展开，第一壳体200的前侧和第二壳体300的前侧可以形成一个平面，使得第一壳体200的前侧和第二壳体300的前侧之间形成约180度角的状态。折叠状态包括完全折叠状态和过渡折叠状态，完全折叠状态可以指电子装置1000完全折叠，第一壳体200的前侧和第二壳体300的前侧可以面向彼此，使得第一壳体200的前侧和第二壳体300的前侧之间形成约0度角的状态，过渡折叠状态可以指电子装置1000处于平坦状态至完全折叠状态之间的任一过渡状态，第一壳体200的前侧和第二壳体300的前侧之间形成约大于0度角且小于180度角的夹角。

随着电子装置1000由平坦状态弯折至折叠状态，第一壳体200的侧部和第二壳体300的侧部之间的空间可以逐渐变宽，第三壳体600可以被第一壳体200和第二壳体300逐渐暴露。当电子装置1000处于完全折叠状态时，第三壳体600的至少一部分可以从第一壳体200的侧部和第二壳体300的侧部之间暴露在外部，第一背板400和第二背板500仍然可以覆盖第三壳体600的一些剩余部分。

结合图4和图8所示，图8为本申请实施例提供的铰链的展开过程示意图。在铰链展开的过程中，第一保持臂241带动第三转轴215绕第一轴线L1按图示箭头的方向旋转，第三转轴215带动第一连杆213绕第五转轴216按图示的箭头的方向旋转；第二保持臂242带动第四转轴225绕第二轴线L2按图示的箭头方向旋转，第四转轴225带动第二连杆223绕第六转轴226按图示的箭头方向旋转。运动块23在第一连杆213和第二连杆223的带动下沿图示箭头的方向（即第三方向z）运动。
可以理解的是，图8所示的铰链的展开的过程是可逆的。在铰链折叠的过程中，第一保持臂241带动第三转轴215绕第一轴线L1按与图示箭头相反的方向旋转，第三转轴215带动第一连杆213绕第五转轴216按与图示的箭头相反的方向旋转；第二保持臂242带动第四转轴225绕第二轴线L2按与图示的箭头相反的方向旋转，第四转轴225带动第二连杆223绕第六转轴226按与图示的箭头相反的方向旋转，运动块23在第一连杆213和第二连杆223的带动下沿与图示箭头的方向相反的方向（即与第三方向z相反的方向）运动。
在铰链展开或折叠的过程中，运动块23始终沿第三方向z或者与第三方向z相反的方向运动，运动块23的第一延伸部231和第二延伸部232始终保持在同一水平面，如此可以使第一连杆213和第二连杆223分别绕第五转轴216和第六转轴226以相同的转动速度旋转，从而实现第一转动机构21和第二转动机构22同步转动的效果。
固定支架10设有第一滑槽14，运动块23可滑动地安装于第一滑槽14内。
如图6所示，第一固定支架11上设有第一滑槽14，第一滑槽14在第三方向z上贯穿第一固定支架11的主体部110。运动块23可滑动地安装于第一滑槽14内，并且只能在第一滑槽14内沿第三方向z或者与第三方向z相反的方向运动，从而保证第一转动机构21和第二转动机构22能够同步转动，并且能够避免运动块23在滑动过程中发生卡顿的情况。
第一滑槽14的壁面上设有凸起141，运动块23的基体部230设有凹槽233，凸起141可滑动地收容于凹槽233内。
如图6所示，第一滑槽14相对设置的两个侧壁上各设有一凸起141，运动块23的基体部230的相对侧与凸起141对应的部分各设有一凹槽233，凸起141可滑动地收容于凹槽233内。如此通过凸起141来进一步限定运动块23的运动方向，防止运动块23发生左右偏斜，从而减小运动块23与第一滑槽14配合的虚位，增加运动块23在运动过程中的稳定性。
在实际应用中，运动块23上设置的凹槽233的数量以及第一滑槽14的壁面上的凸起141的数量可以根据运动块23的尺寸和第一滑槽14的尺寸来设定，尺寸越大的运动块23和第一滑槽14，所需要的凹槽233和凸起141的数量也就越多。运动块23上设置的凹槽233的数量以及第一滑槽14的壁面上凸起141的数量可以根据实际情况设定，可以为1个、2个或3个及以上等，此处不做限制。
保持机构24还包括第一保持件243，第一保持件243上设有第一凸起C11和第二凸起C21，第一保持臂241上设有第一凹槽C32，第二保持臂242上设有第二凹槽C42，第一保持臂241连接于第一转动件211，第二保持臂242连接于第二转动件221，第一转动件211和第二转动件221可转动地连接于第一保持件243。当铰链处于闭合状态或展开状态中的一种状态时，第一凹槽C32收容第一凸起C11，第二凹槽C42收容所述第二凸起C21，当柔性部101处于闭合状态和展开状态中的另一种状态时，第一凸起C11脱离第一凹槽C32，第二凸起C21脱离第二凹槽C42。
在一实施例中，结合图4、图5和图9所示，图9为本申请实施例提供的保持机构的分解示意图，第一固定支架11的主体部110的底面设有卡槽，第一保持件243的主体部分卡合进卡槽内，第一保持件243包括凸出于主体部分的第一凸轮C1和第二凸轮C2，第一凸轮C1可以包括多个第一凸起C11，多个第一凸起C11在第二方向y上凸出于第一凸轮C1的边缘，相邻第一凸起C11之间设有第三凹槽C12，第一转轴214穿过第一凸轮C1，并且可以相对于第一凸轮C1转动。第二凸轮C2可以包括多个第二凸起C21，多个第二凸起C21在第二方向y上凸出于第二凸轮C2的边缘，相邻第二凸起C21之间设有第四凹槽C22，第一转轴214穿过第二凸轮C2，并且可以相对于第二凸轮C2转动。
第一保持臂241的第三凸轮C3可以包括多个在第二方向y上凸出于第三凸轮C3的边缘的第三凸起C31，相邻第三凸起C31之间设有第一凹槽C32，第一转轴214穿过第三凸轮C3。第二保持臂242包括在第一方向x上凸出于第二保持臂242的本体的第四凸轮C4，第四凸轮C4可以包括多个在第二方向y上凸出于第四凸轮C4的边缘的第四凸起C41，相邻第四凸起C41之间设有第二凹槽C42，第二转轴224穿过第四凸轮C4。
第一凸起C11至第四凸起C41中的每一个都有具有平坦末端，平坦末端具有一滑动表面，该滑动表面为各凸起的两个倾斜侧面的衔接面。
保持机构24还包括第一弹性件244和第二弹性件245，第一弹性件244和第二弹性件245均为弹簧。第一弹性件244套设于第一转轴214上，并且夹持于第一保持件243与第一连接部113之间，第二弹性件245套设于第二转轴224上，并且夹持于第一保持件243与第二连接部114之间。
当电子装置1000处于平坦状态或完全折叠状态时，铰链处于展开状态或完全闭合状态，柔性部101处于平坦状态或完全折叠状态，第一保持件243的第一凸轮C1与第一保持臂241的第三凸轮C3普通接合，第一保持件243的第二凸轮C2与第二保持臂242的第四凸轮C4普通接合。
普通接合指的是例如：第一凸轮C1的第一凸起C11收容于第三凸轮C3的第一凹槽C32，第三凹槽C12收容第三凸起C31；第二凸轮C2的第二凸起C21收容于第四凸轮C4的第二凹槽C42，第四凹槽C22收容于第四凸起C41。
当电子装置1000处于过渡折叠状态时，铰链处于过渡闭合状态，柔性部101处于弯曲状态，第一保持件243的第一凸轮C1与第一保持臂241的第三凸轮C3开放接合，第一保持件243的第二凸轮C2与第二保持臂242的第四凸轮C4开放接合。
开放接合指的是例如：第一凸轮C1的第一凸起C11脱离第三凸轮C3的第一凹槽C32，第一凸起C11的滑动表面与第三凸起C31的滑动表面接触；第二凸轮C2的第二凸起C21脱离第四凸轮C4的第二凹槽C42，第二凸起C21的滑动表面与第四凸起C41的滑动表面接触。
在电子装置1000由平坦状态折叠至过渡折叠状态的过程中，第一保持臂241绕第一轴线L1旋转，第二保持臂242绕第二轴线L2旋转，各相互接合的凸轮由普通接合逐渐向开放接合转变，第一凸起C11逐渐脱离第一凹槽C32，第二凸起C21逐渐脱离第二凹槽C42，第一弹性件244和第二弹性件245均被第一保持件243压缩，导致弹性变形量逐渐增大。当第一部102与第二部103之间的角度为0度至30度时，在各弹性件的挤压力以及凸轮的压力角的作用下，电子装置1000在不受外力的情况下可以恢复至平坦状态。
当电子装置1000处于过渡折叠状态时，各相互接合的凸轮为开放接合，各凸轮的压力角为0，第一部102和第二部103之间的角度可以保持在30度至150度，各弹性件的弹性变形量保持不变，电子装置1000在不受外力的情况下，可以保持在过渡折叠状态。
当电子装置1000由过渡折叠状态折叠至完全折叠状态的过程中，各相互接合的凸轮由开放接合逐渐向普通接合转变，第一凸起C11逐渐收容于第一凹槽C32，第二凸起C21逐渐收容于第二凹槽C42，第一弹性件244和第二弹性件245的弹性变形量逐渐减小，当柔性显示面板主体的第一部102与第二部103之间的角度为150度至180度时，在各弹性件的挤压力以及凸轮的压力角的作用下，电子装置1000在不受外力的情况下，可以自动由过渡折叠状态折叠至完全折叠状态。
在实际应用中，保持机构24中保持件的数量不仅限与上述实施例中的1个或2个，也可以为3个或4个及以上等，弹性件的数量则需要适配保持件的数量，对于尺寸越大的电子装置而言，所需要的保持件的数量也就越多。
