如图1至图3所示，图1为本申请实施例提供的电子装置在平坦状态下的正面和背面的结构示意图，图2为本申请实施例提供的电子装置在折叠状态下的结构示意图，图3为本申请实施例提供的电子装置的分解示意图，所述电子装置1000包括柔性显示面板100、第一壳体200、第二壳体300、第一背板400、第二背板500和第三壳体600。
柔性显示面板100包括柔性显示面板主体1，柔性显示面板主体1包括柔性部101和位于柔性部101的相对两侧的第一部102和第二部103，柔性部101是柔性显示面板主体1可以被折叠的部分。第一部102可以设置在第一壳体200的前侧的至少一部分上，第二部103可以设置在第二壳体300的前侧的至少一部分上。

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。

运动块23可运动地连接于第一转动机构21和第二转动机构22，并且位于柔性显示面板主体1的柔性部101之下，在电子装置1000折叠或展开的过程中，运动块23仅沿第三方向z或与第三方向z相反的反向运动，以使第一转动机构21和第二转动机构22能够保持同步运动。
第一转动机构21包括第一转动件211和第一传动件212，第一传动件212可转动地连接于固定支架10，第二转动机构22包括第二传动件222，第二传动件222可转动地连接于固定支架10，第一传动件212和第二传动件222可活动地连接于运动块23，以将第一传动件212和第二传动件222的转动转化为运动块23的直线运动，并驱动运动块23远离或靠近固定支架10，运动块23为一体成型结构。
在本申请实施例中，第一传动件212和第二传动件222分别绕第一轴线L1和第二轴线L2以相反的方向旋转，运动块23在第一传动件212和第二传动件222的驱动下沿直线运动，运动块23沿直线运动的方向与第三方向z平行。

如图4和图5所示，第一铰链2a和第二铰链2b均包括保持机构24，保持机构24包括第一保持臂241和第二保持臂242，第一保持臂241套设于第一转轴214，并与第一转轴214固定连接，第二保持臂242套设于第二转轴224，并与第二转轴224固定连接。
如图7所示，图7为本申请实施例提供的铰链的展开过程的示意图，从左至右为铰链由完全折叠状态展开至平坦状态，铰链的闭合或展开过程是可逆的，从右至左可以看作是铰链由平坦状态折叠至完全折叠状态。
在铰链展开的过程中，第一保持臂241带动第一转轴214绕第一轴线L1按箭头所示的方向旋转，第一齿轮213跟随第一转轴214同向旋转，第二保持臂242带动第二转轴224绕第二轴线L2按箭头所示的方向旋转，第二齿轮223跟随第二转轴224同向旋转。运动块23在齿轮和齿条的啮合作用下，沿第三方向z运动，并逐渐远离固定支架10。
在铰链闭合的过程中，第一保持臂241带动第一转轴214绕第一轴线L1按与箭头所示相反的方向旋转，第一齿轮213跟随第一转轴214同向旋转，第二保持臂242带动第二转轴224绕第二轴线L2按与箭头所示相反的方向旋转，第二齿轮223跟随第二转轴224同向旋转。运动块23在齿轮和齿条的啮合作用下，沿与第三方向z相反的方向运动，并逐渐靠近固定支架10。
在铰链展开或闭合的过程中，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，第一齿轮213和第一齿条232a的啮合速度与第二齿轮223和第二齿条232b的啮合速度相同，使得第一齿轮213和第二齿轮223的转动速度相同，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还包括固定块12，固定块12包括本体部120及自本体部120的相对两侧延伸出的第一连接部121和第二连接部122，第一转动件211穿过第一连接部121，第二转动件221穿过第二连接部122。本体部120设有一个过孔123，过孔123在第三方向z上贯穿本体部120，过孔123用于将固定块12通过螺钉固定连接于第三壳体600上。

第一限位件13卡合在第一固定支架11上，并与第一固定支架11围成第一滑槽14。运动块23滑动安装于第一滑槽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，从而保证第一齿轮213和第二齿轮223能够以相同的转动速度同步转动，还可以避免运动块23在第一滑槽14内滑动的过程中发生卡顿。
进一步的，第一滑槽14的壁面上设有凸起141，运动块23的基体部231设有凹槽233，凸起141可滑动地收容于凹槽233内。
如图6所示，第一固定支架11和第一限位件13面向彼此的一侧均设有一个凸起141，运动块23的基体部231的相对两侧均设有一个凹槽233，凸起141可滑动地收容于对应的凹槽233内。如此通过凸起141和凹槽233的配合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C52，第二保持臂242上设有第二凹槽C62，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C52收容第一凸起C11，第二凹槽C62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C52，第二凸起C21脱离第二凹槽C62。

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的第五凸轮C5普通接合，第一保持件243的第二凸轮C2与第二保持臂242的第六凸轮C6普通接合；第二保持件244的第三凸轮C3与第一保持臂241的第七凸轮C7普通接合，第二保持件244的第四凸轮C4与第二保持臂242的第八凸轮C8普通接合。
普通接合指的是例如：第一凸轮C1的第一凸起C11收容于第五凸轮C5的第一凹槽C52，第五凹槽C12收容第五凸起C51；第二凸轮C2的第二凸起C21收容于第六凸轮C6的第二凹槽C62，第六凹槽C22收容于第六凸起C61；第三凸轮C3的第三凸起C31收容于第七凸轮C7的第三凹槽C72，第七凹槽C32收容第七凸起C71；第四凸轮C4的第四凸起C41收容于第八凸轮C8的第四凹槽C82，第八凹槽C42收容第八凸起C81。
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的第五凸轮C5开放接合，第一保持件243的第二凸轮C2与第二保持臂242的第六凸轮C6开放接合；第二保持件244的第三凸轮C3与第一保持臂241的第七凸轮C7开放接合，第二保持件244的第四凸轮C4与第二保持臂242的第八凸轮C8开放接合。
开放接合指的是例如：第一凸轮C1的第一凸起C11脱离第五凸轮C5的第一凹槽C52，第一凸起C11的滑动表面与第五凸起C51的滑动表面接触；第二凸轮C2的第二凸起C21脱离第六凸轮C6的第二凹槽C62，第二凸起C21的滑动表面与第六凸起C61的滑动表面接触；第三凸轮C3的第三凸起C31脱离第七凸轮C7的第三凹槽C72，第三凸起C31的滑动表面与第七凸起C71的滑动表面接触；第四凸轮C4的第四凸起C41脱离第八凸轮C8的第四凹槽C82，第四凸起C41的滑动表面与第八凸起C81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顺时针旋转，第二保持臂242绕第二轴线L2逆时针旋转，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C52，第二凸起C21逐渐脱离第二凹槽C62，第三凸起C31逐渐脱离第三凹槽C72，第四凸起C41逐渐脱离第四凹槽C82，第一弹性件245至第四弹性件248均被各保持件压缩，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C52，第二凸起C21逐渐收容于第二凹槽C62，第三凸起C31逐渐收容于第三凹槽C72，第四凸起C41逐渐收容于第四凹槽C82，各弹性件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。
进一步的，第一保持件243具有第一固定支撑板2431和第二固定支撑板2432，第一固定支撑板2431位于第一凸轮C1之上，第二固定支撑板2432位于第二凸轮C2之上，第一固定支撑板2431与第二固定支撑板2432、第一凸轮C1和第二凸轮C2以及第一保持件243的主体部分一体成型。当铰链处于展开状态时，第一固定支撑板2431和第二固定支撑板2432可以用于支撑柔性显示面板主体1的柔性部101，以此减轻柔性部101处的折痕。
