本申请属于通信设备技术领域，具体涉及一种电子设备。
随着技术的发展，电子设备的发展也越来越快速，同时，用户对电子设备的要求也越来越高。目前柔性屏幕也广泛地应用于电子设备，进而形成折叠式的电子设备。
折叠式的电子设备在折叠的过程中经常会出现折叠问题。例如，折叠式的电子设备在内折时因为铰链处的折弯半径较小，较容易导致柔性屏幕被过度挤压而出现折痕或折损。折叠式的电子设备在外折时因为铰链处的折弯半径过大，较容易导致柔性屏幕被过度拉扯变形，甚至会导致柔性屏幕发生破裂。可见，目前的折叠式的电子设备在折叠的过程中存在较容易损坏柔性屏幕的问题，最终导致柔性屏幕的使用寿命较短。
发明内容

在电子设备折叠的过程中，连杆机构的第二端相对轴组件转动，通过导向面和推抵部的配合，使得连杆机构运动，带动第一显示屏沿第一设备主体向靠近轴组件的方向移动；
在电子设备展开的过程中，连杆机构的第二端相对轴组件转动，通过导向面和推抵部的配合，使得连杆机构运动，带动第一显示屏沿第一设备主体向远离轴组件的方向移动。
本发明采用的技术方案能够达到以下有益效果：
本发明实施例公开的电子设备中，第一设备主体和第二设备主体通过轴组件转动配合，使得第一设备主体和第二设备主体可以相对转动，实现第一设备主体和第二设备主体展开和折叠。第一设备主体和第二设备主体相对转动的过程中，推抵部沿导向面滑动，进而驱动连杆机构的第二端沿转轴移动。连杆机构的第二端在移动的过程中，连杆机构带动第一显示屏向靠近或远离轴组件的方向移动。因此，该方案可以避免柔性显示屏在电子设备折叠的过程中被拉扯或挤压而损坏，进而达到保护柔性显示屏的目的，解决电子设备折叠过程中柔性显示屏容易损坏的问题。

下面结合图1至图8，通过具体的实施例及其应用场景对本申请实施例提供的电子设备进行详细地说明。
参照图1至图4，本发明所述的电子设备包括第一设备主体100、第二设备主体200、柔性显示屏300、轴组件400和连杆机构500。其中，第一设备主体100和第二设备主体200为基础结构件，可以为电子设备中的各零部件提供安装基础。示例性地，电子设备的其他元件可以为电池、电路板等。需要说明的是，电子设备内部的元件与电子设备的种类或用途有关。为此，本申请实施例不限定电子设备内具体元件的种类和数量。
参照图1和图2，第一设备主体100和第二设备主体200通过轴组件400转动配合，进而使得电子设备可以通过第一设备主体100和第二设备主体200相对转动，实现电子设备折叠或展开。
一种可选的实施例中，第一设备主体100与第二设备主体200之间的夹角范围为第一角度和第二角度。在第一设备主体100与第二设备主体200之间的夹角为第一角度的情况下，柔性显示屏300的显示面位于同一平面，即电子设备处于展开状态。在第一设备主体100与第二设备主体200之间的夹角为第二角度的情况下，第一设备主体100和第二设备主体200相互折叠，即电子设备处于折叠状态。示例性地，第一设备主体100和第二设备主体200可以在0°至180°之间转动。
一种可选的实施例，电子设备的柔性显示屏300为外折式，在电子设备处于折叠的情况下，柔性显示屏300的显示面位于外部。示例性地，在第一设备主体100与第二设备主体200之间的夹角为第二角度的情况下，第一设 备主体100远离柔性显示屏300的一侧叠置于第二设备主体200远离柔性显示屏300的一侧。即电子设备处于折叠状态的情况下，第一显示屏310位于第一设备主体100背离第二设备主体200的一侧，第二显示屏320位于第二设备主体200背离第一设备主体100的一侧。需要说明的是，柔性显示屏300的显示面是指：柔性显示屏300中可显示图像或文字一侧的表面。
参照图1和图2，柔性显示屏300包括第一显示屏310、第二显示屏320。第一显示屏310与第二显示屏320相连，第一显示屏310与第一设备主体滑动配合，第二显示屏320设置于第二设备主体200。
参照图3至图6，连杆机构500的第一端与第一显示屏310相连，连杆机构500的第二端与轴组件400相连，且连杆机构500的第二端和轴组件400中一者设置有推抵部511，另一者设置有导向面410，导向面410相对轴组件400的轴线倾斜设置，推抵部511止抵于导向面410。
在电子设备折叠的过程中，连杆机构500的第二端相对轴组件400转动，通过导向面410和推抵部511的配合，使得连杆机构500运动，带动第一显示屏310沿第一设备主体100向靠近轴组件400的方向移动。
在电子设备展开的过程中，连杆机构500的第二端相对轴组件400转动，通过导向面410和推抵部511的配合，使得连杆机构500运动，带动第一显示屏310沿第一设备主体100向远离轴组件400的方向移动。
参照图3至图6，在电子设备折叠或展开的过程中，连杆机构500随着第一设备主体100相对轴组件400转动，进而带动推抵部511沿导向面410滑动。由于导向面410相对轴组件400的轴线倾斜设置，进而使得连杆机构500的第二段可沿轴组件400移动，并带动第一显示屏310向远离或靠近轴组件400的方向移动。
需要说明的是，第一显示屏310向靠近轴组件400的方向移动是指：第一显示屏310沿自身朝向轴组件400的延伸方向靠近轴组件400。第一显示屏310向远离轴组件400的方向移动是指：第一显示屏310沿自身背离轴组 件400的延伸方向远离轴组件400。
在电子设备折叠的过程中，第一显示屏310向靠近轴组件400的方向移动，使得第一显示屏310靠近轴组件400的一侧可以形成冗余。进一步地，第一显示屏310靠近轴组件400一侧因为受到第一设备主体100和第二设备主体200的作用力，使得第一显示屏310靠近轴组件400的一侧逐渐弯曲。即第一显示屏310靠近轴组件400一侧形成的冗余可以补偿电子设备折叠过程中，柔性显示屏300与轴组件400对应的半径差，达到消除或减小柔性显示屏300与轴组件400相对的部分受到的挤压力的目的。
在电子设备展开的过程中，第一显示屏310向远离轴组件400的方向移动，使得第一显示屏310靠近轴组件400的一侧形成的冗余部分被拉伸，以适应电子设备展开过程中轴组件400处形变，消除或减小柔性显示屏300与轴组件400相对的部分受到的拉力，达到保护柔性显示屏300的目的。并且，第一显示屏310向远离轴组件400的方向移动，还可以消除电子设备展开后柔性显示屏300与轴组件400相对部分的褶皱，提高柔性显示屏300的显示效果。
一种可选的实施例中，推抵部511可以为设置于连杆机构500的第二端的的凸块。当然，推抵部511还可以为设置于连杆机构500的第二端的推杆，推杆固定设置于连杆机构500的第二端，并且推杆的一端凸出于连杆机构500的第二端靠近导向面410的端面，以使连杆机构500的第二端可以通过推杆止抵于导向面410上。可选的，推抵部511与导向面410相抵的一端设置为球形凸面，以便于推抵部511沿导向面410滑动。
可选地实施例中，导向面410可以为设置于轴组件400上的倾斜平面，还可以为设置于轴组件400上的凹面或螺旋面。示例性地，导向面410可以为设置于轴组件400，并环绕连杆机构500的第二端对应轴线的凹槽的槽壁。形成上述实施例中所述的导向面410的方案有很多，例如：可以通过开槽、凸块、安装导轨等方式来实现。为此，本申请不限定形成导向面410的具体 方式。
参照图3至图6，连杆机构500包括第一滑动件510和第一连杆520，第一滑动件510通过第一连杆520与第一显示屏310相连，第一滑动件510形成连杆机构500的第二端，且第一滑动件510与轴组件400滑动配合。
在电子设备折叠的过程中，第一滑动件510沿轴组件400移动，并带动第一显示屏310靠近轴组件400。在电子设备展开的过程中，第一滑动件510沿轴组件400移动，并带动第一显示屏310远离轴组件400。
参照图3和图6，轴组件400通过带动第一滑动件510沿轴组件400移动，进而带动第一连杆520相对第一设备主体100转动。参照图3，第一连杆520在相对第一设备主体100转动的过程中，第一连杆520与轴组件400的轴向的夹角增加或减小，进而可以拉动第一设备主体100向靠近或远离轴组件400的方向移动。
需要说明的是，本申请实施例中所述的第一连杆520与轴组件400的轴向的夹角是指：第一连杆520与轴组件400的转轴对应的轴线方向之间形成的小于或等于90°的夹角。
一种可选地实施例中，在电子设备展开的情况下，第一连杆520与轴组件400垂直，以使第一连杆520与轴组件400之间可以形成“死点”限位，进而可以避免第一显示屏310在电子设备展开的情况下相对第一设备主体100滑动。
示例性地，电子设备折叠的过程中，第一滑动件510可驱动第一连杆520的第一端相对轴组件400移动，以使第一连杆520与轴组件400的轴向的夹角减小。随着第一连杆520与轴组件400的轴向的夹角减小，第一连杆520带动第一设备主体100向靠近轴组件400的方向移动，使得柔性显示屏300中与轴组件400相对的部分能够形成冗余，以避免柔性显示屏300在电子设备折叠的过程中受拉。在电子设备展开的过程中，第一滑动件510驱动第一连杆520的第一端相对轴组件400移动，以使第一连杆520与轴组件400的 轴向的夹角增加。随着第一连杆520与轴组件400的轴向的夹角增加，第一连杆520带动第一设备主体100向远离轴组件400的方向移动，使得柔性显示屏300中与轴组件400相对的部分形成的冗余被消除，以避免柔性显示屏300出现曲翘。
轴组件400驱动第一滑动件510的连接方式有很多。例如：螺纹配合、齿轮齿条传动相连、凸轮机构连接等。为此，本申请实施例不限定轴组件400与第一滑动件510之间连接的具体方式。
进一步可选的实施例中，第一滑动件510设置有安装孔，轴组件400穿过安装孔，并与第一滑动件510转动配合。在电子设备展开或折叠的过程中，第一设备主体100通过第一连杆520作用第一滑动件510相对轴组件400转动，进而使得推抵部511可以沿导向面410滑动，进而带动第一滑动件510沿轴组件400滑动。
示例性地，第一滑动件510可以设置有安装孔，轴组件400具有安装轴，安装轴穿过安装孔并与安装孔间隙配合，进而使得第一滑动件510不仅可相对轴组件400转动，还可沿轴组件400滑动。或者，第一滑动件510与安装轴滑动配合，安装轴可转动地设置。在电子设备折叠或展开的过程中，第一滑动件510沿安装轴向轴组件400的轴向滑动、并通过安装轴转动实现第一滑动件510相对轴组件400转动。需要说明的是，安装轴可转动地设置是指：安装轴可相对其安装基础转动。安装轴的安装基础可以为支架或安装座。
另一种可选地实施中，第一滑动件510上还可以设置有凹槽，轴组件400至少部分位于凹槽内，以使第一滑动件510不仅可以相对轴组件400转动，还可以沿轴组件400滑动。示例性地，第一滑动件510上可以设置有弧形凹槽，轴组件400上设置有与弧形凹槽滑动配合的安装轴。
参照图4至图6，第一连杆520的第一端与第一显示屏310转动相连，第一连杆520的第二端与第一滑动件510转动相连，且第一连杆520相对第一滑动件510绕第一轴线转动，第一轴线与轴组件400垂直。第一轴线与轴 组件400垂直是指：第一轴线与轴组件400对应的轴线垂直。示例性地，轴组件400对应的轴线可以为第一设备主体100相对轴组件400转动的轴线。
示例性地，第一滑动件510在沿轴组件400移动的过程中，第一滑动件510带动第一连杆520的第二端沿轴组件400的轴向移动，使得第一连杆520围绕第一连杆520与柔性显示屏300连接处转动。第一连杆520相对柔性显示屏300转动的过程中，第一连杆520与轴组件400的轴向的夹角增加或减小，进而带动柔性显示屏300的第一段向靠近或远离轴组件400的方向移动。
示例性地，在电子设备折叠的过程中，第一滑动件510带动第一连杆520相对第一显示屏310转动。在第一连杆520相对第一显示屏310转动的过程中，第一连杆520与轴组件400的轴向的夹角减小，进而带动第一显示屏310向靠近轴组件400的方向移动，以避免第一显示屏310和第二显示屏320连接处受拉。
参照图3至图7，连杆机构500还包括滑块530和导轨540，滑块530设置于柔性显示屏300远离显示面的一侧，且滑块530与第一连杆520的第一端转动相连。导轨540设置于第一设备主体100，滑块530与导轨540滑动配合。在电子设备折叠的过程中，第一连杆520拉动滑块530沿导轨540滑动。参照图7，导轨540可以为滑槽，滑块530至少部分内嵌于滑槽内，使得滑块530可以沿滑槽滑动。
导轨540可以为滑块530相对第一设备主体100滑动提供导向。并且，第一设备主体100还可以通过导轨540与滑块530之间的滑动配合，使得第一设备主体100可以为第一连杆520和柔性显示屏300连接处提供支撑。在电子设备折叠或展开的过程中，可以利用导轨540作用滑块530，并带动第一连杆520和第一滑动件510相对轴组件400转动。该实施例可以减小柔性显示屏300与第一连杆520连接处受力，达到保护柔性显示屏300的目的。
滑块530与导轨540滑动配合的方式有很多。示例性地，导轨540可以为“T”型槽，滑块530至少部分位于“T”型槽。导轨540还可以为导杆， 滑块530上设置有通孔，以使滑块530与导杆滑动配合。因此，本实施例不限定滑块530与导轨540滑动配合的具体结构。
一种可选的实施例中，参照图3，第一滑动件510的数量可以为两个，两个第一滑动件510可以对称分布于轴组件400的两端，以使柔性显示屏300受力均衡，进而避免柔性显示屏300沿第一设备主体100和/或第二设备主体200滑动出现卡顿。当然，第一滑动件510的数量还可以为多个，多个第一滑动件510可以沿轴组件400的轴向均匀分布于轴组件400。为此，本申请不限定第一滑动件510的具体数量。
参照图4和图5，电子设备还包括弹性件600，弹性件600分别与轴组件400和第一滑动件510相连，且弹性件600驱动第一滑动件510，以使推抵部511止抵于导向面410。即弹性件600产生的弹力分别作用轴组件400和第一滑动件510，使得推抵部511在电子设备折叠或展开的过程中可以保持止抵于导向面410的状态，进而在电子设备反复折叠或展开的过程中，可以实现第一滑动件510复位。
在电子设备使用过程中，柔性显示屏300可能受到各个方向的作用力，例如：手指在柔性显示屏300表面滑动过程中产生的摩擦力。通过设置弹性件600，可以避免第一滑动件510向背离导向面410的方向移动，进而可以利用弹性件600和导向面410限定第一滑动件510的位置，进而可以避免用户操作柔性显示屏300的过程中，出现柔性显示屏300相对第一设备主体100滑动。因此，上述实施例中所述的电子设备无需增设避免柔性显示屏300相对第一设备主体100滑动的阻尼结构。
参照图3、图4和图8，轴组件400开设有限位槽420，限位槽420内陷于导向面410。在电子设备展开和/或折叠的情况下，推抵部511至少部分内陷于限位槽420。限位槽420与推抵部511限位配合，不仅可以限制第一设备主体100相对轴组件400转动，还可以增加柔性显示屏300相对第一设备主体100滑动的阻力，进而避免柔性显示屏300在电子设备第一设备主体100 和第二设备主体200无相对转动的情况下相对第一设备主体100滑动。
限位槽420的数量为多个，且限位槽420沿推抵部511相对导向面410移动的轨迹间隔设置。参照图3，第一设备主体100相对轴组件400转动的过程中，推抵部511相对导向面410的轨迹为围绕第一设备主体100相对轴组件400转动的轴线。上述实施例中，通过设置多个限位槽420，不仅可以增加第一设备主体100相对轴组件400转动过程中受到的阻力，还可以通过不同的限位槽420使得第一设备主体100和第二设备主体200保持在不同的夹角。例如，可以通过限位槽420与推抵部511限位配合使得第一设备主体100和第二设备主体200的夹角为锐角。第一设备主体100和第二设备主体200的夹角为锐角的情况下，可以利用第一设备主体100和第二设备主体200中的一者作为支撑座，另一者支撑部分柔性显示屏300。示例性地，在利用电子设备进行画面显示的情况下，可以利用第一设备主体100和第二设备主体200中的一者作为支撑座，位于另一者上的柔性显示屏300用于显示画面，进而使得柔性显示屏300中显示画面的部分能够倾斜设置，以便于用户观看柔性显示屏300中显示的画面。
参照图4和图8，一种可选地实施例中，轴组件400包括圆柱凸轮，导向面410设置于圆柱凸轮靠近推抵部511的一侧。进一步地，限位槽420可以为设置于圆柱凸轮中设置导向面410的一端的球面凹槽。
参照图3和图5，第二显示屏320与第二设备主体200滑动配合，连杆机构500包括第二滑动件550和第二连杆560，第二滑动件550形成连杆机构500的第二端，第二滑动件550与轴组件400滑动配合，且第二滑动件550通过第二连杆560与第二显示屏320相连。
示例性地，第二连杆560和第一连杆520结构可以相同，第二滑动件550和第一滑动件510的结构可以相同。进一步地，第二显示屏320和第二连杆560的连接方式与第一显示屏310和第一连杆520的连接方式可以相同。为此，本申请不再详细阐述第二显示屏320和第二连杆560的连接方式。
同理，第二连杆560和第二滑动件550的连接方式与第一连杆520和第一滑动件510的连接方式可以相同。为此，本说明书不再阐述第二连杆560和第二滑动件550的连接方式。第二滑动件550和轴组件400的连接方式与第一滑动件510和轴组件400的连接方式可以相同，本实施例不再阐述第二滑动件550和轴组件400的连接方式。
上述实施例中，第一显示屏310和第二显示屏320均可以在电子设备折叠的过程中向靠近或远离轴组件400的方向移动，进而可以避免柔性显示屏300在电子设备折叠或展开的过程中受拉或受压。并且，第一显示屏310和第二显示屏320均相对轴组件400移动，可以降低柔性显示屏300与轴组件400之间的摩擦力。电子设备折叠或展开过程中，可以进一步减小对柔性显示屏300的磨损。
参照图3至图5，轴组件400包括第一转轴430、第二转轴440和支架450，第一转轴430和第二转轴440均与支架450相连，且第一转轴430和第二转轴440相互平行。第一设备主体100与第一转轴430转动配合，第二设备主体200与第二转轴440转动配合。第一滑动件510与第一转轴430相连。第二滑动件550与第二转轴440相连。
示例性地，支架450上设置有第一安装孔和第二安装孔，第一安装孔和第二安装孔平行且间隔设置。第一转轴430穿过第一安装孔并与第一安装孔转动配合。第二转轴440穿过第二安装孔并与第二安装孔转动配合。
上述实施例中，第一转轴430和第二转轴440平行且间隔设置，进而使第一设备主体100和第二设备主体200分为围绕两个相互平行的轴线转动，进而使得第一设备主体100和第二设备主体200相互避让的空间增加，以避免第一设备主体100和第二设备主体200在电子设备展开或折叠的过程中相互干扰。示例性地，第一转轴430与第二转轴440之间的间距为第一距离，第一转轴430距离第一设备主体100中远离第一显示屏310的一侧的距离为第二距离。第二转轴440距离第二设备主体200中远离第二显示屏320的一 侧的距离为第三距离。第一距离不小于第二距离与第三距离之和，进而在电子设备处于外折的情况下，第一设备主体100和第二设备主体200能够更好地贴合，以减小电子设备叠合后的厚度，提高电子设备折叠后的舒适度。
一种可选地实施例中，支架450靠近柔性显示屏300的一侧设置有弧形支撑面，以使支架450可用于支撑柔性显示屏300。示例性地，在电子设备处于折叠状态的情况下，柔性显示屏300中与轴组件400相对的部分可支撑于支架450。另外，支架450靠近柔性显示屏300的一侧设置有弧形支撑面可以有效引导柔性显示屏300中与轴组件400相对的部分形变，进而避免柔性显示屏300中与轴组件400相对的部分的局部过渡弯曲。进一步地，支架450靠近柔性显示屏300的一侧设置为圆弧形支撑面。在电子设备处于折叠状态的情况下，柔性显示屏300中支撑于圆弧形支撑面的部分对应的曲率一致。

参照图3至图5，第一设备主体100设置有第一齿轮110，第二设备主体200设置有第二齿轮210，第一齿轮110与第二齿轮210啮合，且第一设备主体100可通过第一齿轮110和第二齿轮210带动第二设备主体200相对轴组件400转动。第一设备主体100相对轴组件400转动的过程中，第一设备主体100可以通过第一齿轮110和第二齿轮210带动第二设备主体200相对轴组件400转动，进而实现第一设备主体100和第二设备主体200相对轴组件400同步转动。示例性地，第一设备主体100的第一齿轮110与第一转轴430转动配合。第二设备主体200的第二齿轮210与第二转轴440转动配合。
参照图3，轴组件400还包括支撑件，支撑件设置于支架450靠近柔性显示屏300的一侧，且柔性显示屏300至少部分支撑于支撑件，以通过支撑件可以为柔性显示屏300中与轴组件400相对的部分提供支撑力。

一种可选地实施例中，支撑件可以固定设置于支架450上。示例性地，支撑件可以与支架450通过螺钉固定。当然，支撑件与支架450还可以设置为一体结构。
上述实施例中，在电子设备处于折叠状态的情况下，可以通过支撑板为柔性显示屏300中与轴组件400相对的部分提供支撑，以避免柔性显示屏300中与轴组件400相对的部分受力凹陷。在电子设备处于展开状态的情况下，支撑板的至少部分可以为柔性显示屏300中与轴组件400相对的部分提供支撑。
参照图1至图3和图7，柔性显示屏300还包括第一支撑板330和第二支撑板340。第一支撑板330设置于第一显示屏310。第二支撑板340设置于第二显示屏320。第一支撑板330与第一设备主体100滑动配合，且第一支撑板330可沿第一设备主体100向靠近或远离轴组件400的方向移动。第二支撑板340与第二设备主体200滑动配合，且第二支撑板340可沿第二设备主体200向靠近或远离轴组件400的方向移动。

参照图3和图7，第一设备主体100和第二设备主体200上设置有滑槽120，柔性显示屏300的第一段至少部分位于第一设备主体100的滑槽120 内，以使柔性显示屏300可以与第一设备主体100滑动配合。同理，柔性显示屏300的第二段至少部分位于第二设备主体200的滑槽120内，以使柔性显示屏300的第二段与第二设备主体200滑动配合。
示例性地，第一支撑板330在轴组件400的轴向的尺寸大于第一显示屏310在轴组件400的轴向的尺寸，以使第一支撑板330在轴组件400的轴向的两侧可以凸出于第一显示屏310，进而通过第一支撑板330凸出于第一显示屏310的部分的至少部分位于滑槽120内，实现第一显示屏310与第一设备主体100滑动配合。同理，第二支撑板340在轴组件400的轴向的尺寸大于第二显示屏320在轴组件400的轴向的尺寸，以使第二支撑板340在轴组件400的轴向的两侧可以凸出于第二显示屏320，进而通过第二支撑板340凸出于第二显示屏320的部分的至少部分位于滑槽120内，实现第二显示屏320与第二设备主体200滑动配合。
