图2是可折叠电子设备部件示意图。如图2所示，可折叠电子设备的显示屏104包括第一固定部1041、第二固定部1042以及弯曲部1043，其中，第一固定部1041用于与第一机身101固定连接，第二固定部1042用于与第二机身103固定连接，弯曲部1043用于与第一固定部1041、第二固定部1042以及转轴组件102发生相对位移，以对应于显示屏104的折叠态和展开态发生变化。
其中，显示屏104包括显示模组和透明盖板，显示模组能够显示图像以及视频等，显示模组可以采用液晶显示屏(liquidcrystaldisplay，LCD)，有机发光二极管(organiclight-emittingdiode，OLED)，有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrixorganiclightemittingdiode的，AMOLED)，柔性发光二极管(flexlight-emittingdiode，FLED)，Miniled，MicroLed，Micro-oLed，量子点发光二极管(quantumdotlightemittingdiodes，QLED)等。透明盖板覆盖于显示模组的外侧，起到保护显示模组的作用。透明盖板可以为玻璃盖板，当然也可以为其他能够起到保护功能的透明材料。显示屏104还可以兼具触控的功能，即显示屏104可以为触控屏。显示 屏104用于显示图像的一侧表面即为透明盖板背离显示模组的一侧表面。
进一步如图2所示，可折叠电子设备还包括边框105，边框105、第一机身101以及第二机身103固定连接后，可以在第一机身101上设置第一固定部1041，以及在第二机身103上设置第二固定部1042，以使边框105、第一机身101以及第二机身103对显示屏104起到限位和支撑作用。
这里需要说明的是，边框105可以与第一机身101以及第二机身103一体成型，以使第一机身101、第二机身103以及边框105共同作为可折叠电子设备的中框，边框105也可以作为中框的一部分与作为可折叠电子设备的壳体的第一机身101以及第二机身103固定连接，本申请对上述各个部件的连接次序和连接关系不做限制。
图3是可折叠电子设备转轴组件示意图。如图3所示。转轴组件102可以包括摆臂1021、楔形块1022、门板1023、盖板1024、基座1025以及轴盖1026。其中，轴盖1026与弯曲部1043相对设置，盖板1024位于轴盖1026与弯曲部1043之间，并与轴盖1026固定连接形成腔体；基座1025的至少一部分位于腔体内部。盖板1024、基座1025与轴盖1026形成的组合体用于作为转轴组件102的基体1020，以便于设置其他部件。摆臂1021与楔形块1022一体成型，且摆臂1021的虚拟滑舌(如图3中M1区域所示)与基座1025和盖板1024形成的环形槽连接，同时，虚拟滑舌还与门板1023的虚轴连接。在该种连接方式下，楔形块1022与边框105固定连接，由于显示屏104也与边框105固定连接，因此，楔形块1022、摆臂1021以及门板1023相对于基体1020产生的位移可以使边框105、显示屏104完成由折叠态至展开态的变化。
这里需要说明的是，图3仅示出了转轴组件102的局部示意图，即转轴组件102的一侧端部由转轴组件102的端面沿转轴组件的轴向延伸一定距离的区域，实际的转轴组件102还包括与示意图轴对称设置的另一部分，图3中未示出。本申请实际表述均以转轴组件102的整体设置进行表述。
图4是可折叠电子设备的跌落状态示意图。如图4所示，以可折叠电子设备处于折叠态为例，由于惯性作用，可折叠电子设备的轴侧角通常先跌落至地面，即可折叠电子设备发生轴侧角跌，在轴侧角跌过程中，轴侧角与地面接触的位置不变，可折叠电子设备会受力展开，此时，边框105以及显示屏104会产生靠近转轴组件102的位移，导致弯曲部1043与盖板1024发生碰撞，进而导致显示屏104的损坏。
图5(a)是可折叠电子设备跌落状态的剖面变化示意图。
图5(a)中的A是可折叠电子设备未跌落前的整体示意图。其中，H1是可折叠电子设备的剖切平面，Q1是该剖切平面H1的投影方向。图5(a)中的B是可折叠电子设备的俯视图，其中，剖面线K1是剖切平面H1在俯视图中的投影。图5(a)中的C是可折叠电子设备Q1方向的剖面图的局部示意图。如图5(a)中C所示的剖面图是根据如图5(a)中A和B所示进行剖切得到的。图5(a)中的D是可折叠电子设备沿如图5(a)中的C所示的剖面线K2进行剖切的局部示意图。图5(a)中的E是可折叠电子设备未跌落前基体和弯曲部的空间关系简化示意图。其中，剖面线K3是剖切平面H1在侧视图方向的投影。
图5(b)是如图5(a)中的C的M2区域对应的局部放大示意图。即仅示出了转轴组件102的一侧端部由转轴组件102的端面沿转轴组件102的轴向方向延伸一定距 离的区域的剖面示意图。如图5(b)所示，以可折叠设备处于折叠态时发生轴侧角跌为例，在可折叠电子设备未跌落前，弯曲部1043在盖板1024面向弯曲部1043的一侧表面上具有投影区域，该表面上的投影区域与弯曲部1043之间具有间隙。该投影区域与弯曲部1043之间每处间隙都相等。即如图所示的P1、P2相等。
下述图5(c)以及图5(d)均为如图5(b)中所示的区域所对应的局部剖面图。图5(c)是可折叠电子设备的跌落状态局部剖面变化图。如图5(c)所示，在可折叠电子设备处于轴侧角跌的初始状态时，轴侧角(如图5(c)中M3区域所示)与地面接触，此时，该接触区域速度降为0，而其他区域由于惯性继续下落，边框105和显示屏104产生靠近转轴组件102的位移，此时，弯曲部1043的一侧端部首先与盖板1024接触，即如图所示的P1等于0，弯曲部1043的一侧端部由转轴组件102的端面沿转轴组件102的轴向方向延伸一定距离的区域与盖板1024的一侧表面之间具有间隙，即如图所示的P2具有一定距离，示例的，P2等于0.1毫米。此时，M3区域的轴侧角受到了较大的应力。
图5(d)是可折叠电子设备的跌落状态局部剖面变化图。如图5(d)所示，在可折叠电子设备处于轴侧角跌的结束状态时，弯曲部1043与盖板1024面向弯曲部1043的一侧表面完全接触，即如图所示的P1等于0，且P2等于0。此时，M3区域持续承受较大的应力。如图5(a)-图5(d)所示，可折叠电子设备的跌落状态变化过程中，轴侧角跌的初始状态至结束状态受到的撞击应力较大，因此，传统可折叠电子设备中转轴组件102的设置方式在轴侧角跌时极易导致显示屏104发生损坏。
为了解决可折叠电子设备跌落时，弯曲部1043通常会与用于设置转轴组件102的基体发生撞击，导致弯曲部1043发生损伤的概率较高的问题，本申请实施例示出了一种折叠组件。
本申请示出的折叠组件，可以应用至可折叠电子设备中，本申请的可折叠电子设备包括但不限于手机、显示器、平板电脑、车载电脑等。本申请实施例对上述可折叠电子设备的具体形式不做特殊限制。
图6是本申请实施例示出的折叠组件的第一种结构的爆炸示意图。如图6所示，折叠组件可以包括：第一机身1、第二机身2以及转轴3，转轴3可以包括基体4，基体4可以设置于第一机身1与第二机身2之间，基体4包括面向可折叠电子设备的显示屏5的弯曲部51的第一表面41。
本申请实施例中，以基体4的轴向方向为Y轴方向，以基体4的厚度方向为Z轴方向，以垂直于Y轴及Z轴所在平面的方向为X轴方向。其中，以如图6所示的箭头指示方向为X轴、Y轴、Z轴的正向，本申请以下实施例中涉及到的X轴方向、Y轴方向以及Z轴方向均以此为准。
图7中的A是本申请实施例示出的折叠组件的第一种结构的整体示意图。其中，H2是可折叠电子设备的剖切平面，Q2是该剖切平面H2的投影方向。图7中的B是本申请实施例示出的可折叠电子设备的俯视图，其中，剖面线R1是剖切平面H2在俯视图中的投影。图7中的C是本申请实施例示出的可折叠电子设备Q2方向的剖面图的局部示意图。如图7中的C所示的剖面图是根据如图7中的A和B所示进行剖切得到的。图7中的D是可折叠电子设备沿如图7中的C所示的剖面线R2进行剖切的局 部示意图。图7中的E是可折叠电子设备基体和弯曲部的空间关系简化示意图。其中，剖面线R3是剖切平面H2在侧视图方向的投影。
这里需要说明的是，折叠组件的端部即X1对应的区域，包括基体4的端部，以及弯曲部51的端部。其中，弯曲部51的端部由弯曲部51的一侧端面沿Y轴方向延伸一定的距离形成，基体4的端部由基体4的一侧端面沿Y轴方向延伸一定距离形成。本申请实施例中，基体4包括至少一侧端部，弯曲部51包括至少一侧端部。
图8中的A为如图7中C的M4区域对应的局部放大示意图。图8中的B为如图7中C的M4区域对应的局部立体示意图。
如图8中的A和B所示，在一些实施例中，弯曲部51的至少一侧端部由弯曲部51的端面沿Y轴方向延伸第一距离D1形成，示例的，第一距离D1可以为13毫米。这里需要说明的是，本申请实施例不对第一距离D1的具体数值进行设置，第一距离D1可以小于或等于80毫米。
第一表面41包括凹陷部411和支撑部412，其中，支撑部412是第一表面41除凹陷部411以外的区域，沿第一方向，弯曲部51的至少一侧端部在第一表面41形成投影区域M5，凹陷部411对应于投影区域M5设置，并且凹陷部411包含投影区域M5。其中，第一方向是基体4的轴向方向，即Y轴方向。
沿第二方向，弯曲部51与凹陷部411之间具有第一间隙S1，弯曲部51与支撑部412之间具有第二间隙S2，第一间隙S1大于第二间隙S2，其中，第二方向是基体的厚度方向，即Z轴方向。这样，凹陷部411可以在可折叠电子设备轴测角跌时对显示屏5发生避让。
进一步如图6所示，在一些实施例中，基体4可以包括轴盖42、基座43以及盖板44。其中，轴盖42可以与弯曲部51相对设置，盖板44位于轴盖42与弯曲部51之间，并与轴盖42固定连接形成腔体，基座43的至少一部分位于腔体内部。
在一些实施例中，转轴3还可以包括摆臂组件6，摆臂组件6可以包括摆臂61、楔形块62以及门板63。
进一步如图6所示，显示屏5设置于第一机身1以及第二机身2上。根据显示屏5与第一机身1与第二机身2的连接关系不同，显示屏5可以包括弯曲部51、第一固定部52以及第二固定部53。第一固定部52用于与第一机身1固定连接，第二固定部53用于与第二机身2固定连接，弯曲部51与摆臂组件6以及基体4的位置相对应，处于自由状态，能够与第一固定部52以及第二固定部53产生相对位移，以适应折叠组件的折叠和展开功能。当折叠组件处于折叠态时，弯曲部51可以为水滴型的弯折状态。这里需要说明的是，显示屏5的具体材质可以参照上述实施例中的显示屏104设置，本申请对此不予赘述。
边框7可以设置于显示屏5、第一机身1以及第二机身2边缘，并与这些部件固定连接，起到限位和支撑作用。这里需要说明的是，边框7可以与第一机身1以及第二机身2一体成型，以使第一机身1、第二机身2以及边框7共同作为可折叠电子设备的中框。边框7也可以作为为中框的一部分与作为可折叠电子设备的壳体的第一机身1以及第二机身2固定连接。
图9是本申请实施例示出的摆臂组件与基体组合示意图。如图9所示，摆臂61 可以与楔形块62一体成型，且摆臂61的虚拟滑舌(如图9中的M6区域所示)与基座43和盖板44形成的环形槽连接，同时，虚拟滑舌还与门板63的虚轴连接。由于楔形块62与边框7固定连接，且显示屏5也与边框7固定连接，因此，摆臂11、楔形块12以及门板13相对于基体4产生的沿Z轴方向的位移可以使边框7以及显示屏5完成由折叠态至展开态的变化。
这里需要说明的是，转轴3与基体4均包括但不限于本申请实施例所示的部件，转轴3和基体4均可以设置更多或者更少的部件，本申请对此不做限制。
其中，第一表面41可以为盖板44面向弯曲部51的一侧表面，当基体4为不包括盖板44的其他结构时，第一表面41也可以为其他部件面向弯曲部51的一侧表面。本申请实施例中对第一表面41为何种部件的表面不进行限制，第一表面41可以为与弯曲部51发生撞击的任何部件的表面。
在一些实施例中，基座43可以与轴盖42为一体成型的结构，基座43也可以与轴盖42为分离的结构，本申请实施例对转轴3以及基体4的各部件的连接方式不进行限制。
图10是本申请实施例示出的基体局部示意图。图10中的A是本申请实施例示出的折叠态的基体局部示意图。图10中的B是本申请实施例示出的展开态的基体局部示意图。如图10中的A和B所示，在一些实施例中，凹陷部411包括面向基体的端面401的第一端402，基体4的端面401与第一端402之间沿Y轴方向具有第二距离D2。由于基体4的边缘通常包括轴盖42的一部分以用于在可折叠电子设备的展开态支撑显示屏5，因此，凹陷部411无需从基体4的端面401进行设置以对显示屏5进行避让，仅需对应弯曲部51的端部在第一表面41的投影区域设置即可，此时，第二距离D2可以为轴盖42的厚度。这里需要说明的是，本申请仅以轴盖42进行示例性说明，基体的端面401与凹陷部411的第一端402之间的第二距离D2也可以设置为其他一种或多种部件的结构。需要注意的是，凹陷部411的区域可以大于或等于弯曲部51的端部在第一表面41的投影区域，以在弯曲部51发生轴侧角跌时提供一定的位移空间，避免弯曲部51与轴盖42发生碰撞。
具体实现中，凹陷部411可以设置为沉槽、倾斜面的至少一种，本申请实施例不对凹陷部411的具体形状进行限制，凹陷部411还可以为阶梯形或者其他形状。基于此类沉槽、倾斜面、阶梯形的设置方式，凹陷部411沿Z轴方向的高度低于支撑部412沿Z轴方向的高度，凹陷部411可以在可折叠电子设备轴测角跌时对显示屏5发生避让。因此，任何采用此类设置方式，以及此类设置方式的衍生形态进行设计的凹陷部411均可应用于本申请实施例中。
图11是本申请实施例示出的第一表面俯视示意图。如图11所示，第一表面41可以为光滑表面，也可以在其上设置其他部件。在一些实施例中，倾斜面可以包括连续面、间断面的至少一种。本申请实施例不对凹陷部411所在平面的连续性进行限制。在一些实施例中，倾斜面可以包括倾斜曲面、倾斜平面的至少一种。在一些实施例中，倾斜面可以为包括曲率逐渐增大的曲面、曲率逐渐减小的曲面的至少一种。
本申请实施例的折叠组件的第一种结构以凹陷部411为倾斜面，且该倾斜面为连续曲面进行示例。
图12是本申请实施例提供的第三距离示意图。在一些实施例中，凹陷部411包括背离基体4的端面的第二端403，第二端403与基体4的端面之间具有第三距离D3，第三距离D3大于第二距离D2。图12中的A是本申请实施例示出的第三距离剖面示意图。该剖面与如图7中的C为同一剖面。图12中的B是本申请实施例示出的第三距离的立体示意图。如图12中的A和B所示，凹陷部411的第一端402与第二端403之间对应的与弯曲部51之间的间隙逐渐减小，支撑部412与对应的弯曲部51之间的间隙不变。
图13(a)-图13(f)是本申请实施例提供的凹陷部示意图。
图13(a)是本申请实施例示出的凹陷部的俯视图。
图13(b)是本申请实施例示出的凹陷部的立体图。如图13(a)和图13(b)所示，凹陷部411包括点O1、点O2、点O3、点O4。其中，点O1、点O2和点O3为凹陷部411俯视图中的顶点。点O2、点O3和点O4为凹陷部411侧视图中的顶点。
图13(c)是本申请实施例示出的点O1的空间位置关系。如图13(b)及如图13(c)所示，点O1在第一表面41的支撑部所在的平面。其中，点O1与基体4的端面之间沿Y轴负向具有第一间距T1，示例的，第一间距T1可以为13毫米。基体4沿X轴方向具有两个侧面，点O1与基体4沿X轴正向的侧面之间具有第二间距T2，示例的，第二间距T2可以为3.7毫米，点O1与基体4沿X轴负向的侧面之间具有第三间距T3，示例的，第三间距T3可以为3.7毫米。点O1与基体4的底面之间沿Z轴负向具有第四间距T4，示例的，第四间距T4可以为6毫米。
图13(d)是本申请实施例示出的点O2的空间位置关系。如13(d)所示，点O2在第一表面41的支撑部所在的平面。其中，点O2与基体4端面之间沿Y轴负向具有第五间距T5，示例的，第五间距T5为1毫米。点O2与基体4沿X轴正向的侧面之间具有第六间距T6，示例的，第六间距T6为1.2毫米。点O2与基体4沿X轴负向的侧面之间具有第七间距T7，示例的，第七间距T7为6.2毫米。由于点O2与点O1在同一平面上，因此点O2与基体4的底面之间沿Z轴负向的距离与第四间距T4相同，附图中未示出。
图13(e)是本申请实施例示出的点O3的空间位置关系。如图13(e)所示，点O3在第一表面41的支撑部所在的平面。其中，点O3与基体4端面之间沿Y轴负向具有第八间距T8，示例的，第八间距T8为1毫米。点O3与基体4沿X轴正向的侧面之间具有第九间距T9，示例的，第九间距T9为6.2毫米。点O3与基体4沿X轴负向的侧面之间具有第十间距T10，示例的，第十间距T10为1.2毫米。由于点O3与点O1在同一平面上，因此点O3与基体4的底面之间沿Z轴负向的距离与第四间距T4相同，附图中未示出。
图13(f)是本申请实施例示出的点O4的空间位置关系。如图13(f)所示，点O4与点O2和点O3在同一平面上，因此点O4与基体4端面之间沿Y轴负向的距离与第八间距T8相同，附图中未示出。点O4与基体4沿X轴正向的侧面之间具有第十一间距T11，示例的，第十一间距T11为3.7毫米。点O4与基体4沿X轴负向的侧面之间具有第十二间距T12，示例的，第十二间距T12为3.7毫米。点O4与基体4的底面之间沿Z轴负向具有第十三间距T13，示例的，第十三间距T13可以为3毫米。
进一步如图13(e)和如图13(f)所示，凹陷部411的轴向长度L1为点O1与凹陷部411的第一端402所在的沿Z轴方向的平面之间的距离，示例的，凹陷部411的轴向长度L1可以为12毫米。凹陷部411的径向长度L2为点O2与点O3在径向方向上的投影之间的距离，示例的，凹陷部411的径向长度L2可以为5毫米。基于上述实施例中的结构，第一间隙S1与第二间隙S2具有对应的大小关系。在一些实施例中，当第二间隙S2为0.25毫米时，第一间隙S1可以大于0.25毫米。示例的，第一间隙S1为0.3毫米。
其中，第一间隙S1可以根据第二间隙S2的大小选取合适的数值进行设计，若第二间隙S2的数值较小，可以将第一间隙S1的数值设计的相对较大，以对显示屏5产生更多的避让，若第二间隙S2的数值较大，由于弯曲部51与基体4之间已经具备了一定的避让空间，可以将第一间隙S1的数值设计的相对较小。本申请实施例对第一间隙S1和第二间隙S2大小不进行限制。本申请实施例示出的间隙范围仅用于进行示例性说明，具体间隙大小可以根据实际情况进行设置。
在一些实施例中，当可折叠电子设备处于折叠态时，第二间隙S2可以大于或等于0.25毫米。
在一些实施例中，当可折叠电子设备处于折叠态时，第二间隙S2可以小于或等于0.4毫米。
在一些实施例中，当可折叠电子设备处于折叠态时，第一间隙S1与第二间隙S2的差值范围为[0.1，0.3]毫米。
这里需要说明的是，上述实施例涉及的数值仅用于进行示例性说明，上述数值仅用于说明凹陷部411各个点形成的空间关系，由于第十三间距T13小于第四间距T4，这种高低差值形成了凹陷部411，这样，基体4由于设置有凹陷部411，使其薄于支撑部412，在支撑部412能够对显示屏5进行支撑的情况下，凹陷部411还可以在显示屏5发生轴测角跌时产生避让。
基于上述实施例中的数值生成的凹陷部411，能够使第一表面41的下沉量较小，不会对第一表面41的强度产生较大的影响，因此，本申请实施例示出的技术方案不会对可折叠电子设备展开态时对显示屏5的支撑能力产生影响。
图14(a)是可折叠电子设备跌落状态的局部剖面示意图。其中，图12(a)是如图7中C的M4区域对应的局部放大示意图。如图14(a)所示，以可折叠电子设备处于折叠态时跌落为例，在可折叠电子设备未跌落前凹陷部411的第一端402与第二端403之间对应的与弯曲部51之间的间隙逐渐减小，即如图14(a)所示的第一间隙S1大于第二间隙S2。示例的，S1为0.15毫米，S2为0.1毫米。
下述图14(b)以及图14(c)均为如图14(a)中所示的区域对应的局部剖面图。图14(b)是可折叠电子设备的跌落状态局部剖面变化图。如图14(b)所示，在可折叠电子设备处于轴侧角跌的初始状态时，轴侧角(如图14(b)中的M6区域所示)与地面接触，此时，该区域的速度降为0，由于第一表面41具有凹陷部411，弯曲部51可以继续下落，同时，其他区域由于惯性继续下落，边框7和弯曲部51产生靠近第一表面41的位移，该过程中，弯曲部51的一侧端部与凹陷部411的第一端并未接触，即如图所示的第一间隙S1具有一定距离，第二间隙S2具有一定的距离，示例的，S1 为0.1毫米，S2为0.1毫米。第一表面41在轴侧角跌的初始状态对弯曲部51产生的避让可以减少该过程中弯曲部51受到的应力。
图14(c)是本申请实施例示出的可折叠电子设备的跌落状态局部剖面变化图。如图14(c)所示，在可折叠电子设备处于轴侧角跌的结束状态时，弯曲部51与第一表面41完全接触，即如图所示的P1等于0，且P2等于0。此时，由于轴侧角跌的初始状态已经消耗了较多的应力，因此，在轴侧角跌的结束状态，M6区域承受的应力较小，弯曲部51受到的应力较小，并不会使显示屏5发生较大的变形导致其损坏。
在一些实施例中，当可折叠电子设备处于折叠态时，第一间隙S1为第一数值，第二间隙S2为第二数值，第一数值大于第二数值；当可折叠电子设备处于展开态时，第一间隙S3为第三数值，第二间隙S2为第四数值，第三数值大于第四数值；其中，第一数值与第三数值不同，第二数值与第四数值不同。这样，基于折叠组件的第一种结构，凹陷部411在可折叠电子设备折叠态和展开态与弯曲部51之间的间隙发生变化，产生不同的效果。当可折叠电子设备处于折叠态时，第一间隙S1在可折叠电子设备轴侧角跌时对显示屏5发生避让，若第一间隙S1采用较小的第一数值，则可以在进行避让的同时减小对显示屏5的支撑强度的影响，若第一间隙S1采用较大的第一数值，则可能影响显示屏5的支撑强度。
这里需要说明的是，本申请实施例仅示出了第一数值与第三数值不同，以及第二数值与第四数值不同的情况，具体实现中，存在第一数值等于第三数值，以及第二数值等于第四数值的情况，本申请实施例对此不做限制。
为了在产生较好的避让效果的情况下同时不影响显示屏5的支撑强度。折叠组件还可以包括第一转动件8，以使第一转动件8在可折叠电子设备的展开态可以代替第一表面41对显示屏5进行支撑，避免由于第一表面41设置凹陷部411改变基体4对显示屏5的支撑强度。
图15是本申请实施例示出的第一转动件结构示意图。图15中的A是本申请实施例示出的第一转动件的剖面结构示意图。该示意图与如图7中的C的M4区域为同一区域。如图15中的A所示，第一表面41的凹陷部411之间的区域设置有凹槽，凹槽内设置有第一转动件8，第一转动件8包括第二表面81，第二表面81为第一转动件8背离凹槽底面的一侧表面，第二表面81与凹槽的开口平行。图15中的B是本申请实施例示出的展开态的浮动门板的立体示意图。第一转动件8可以与摆臂61连接，这样，在可折叠电子设备展开态，第一转动件8能够支撑弯曲部51。图15中的C示出了可折叠电子设备处于展开态在如图15中A的剖面线R4处的进行剖切的示意图。如图15中的C所示，当可折叠电子设备在展开过程中，摆臂61带动第一转动件8，以使第一转动件8产生靠近显示屏5的沿Z轴方向的位移，进而在可折叠电子设备处于完全展开态时支撑显示屏5。图15中的D示出了可折叠电子设备处于折叠态在如图15中A的剖面线R4处的进行剖切的示意图。当可折叠电子设备处于折叠态时，摆臂11带动第一转动件8，以使第一转动件8产生背离显示屏5的位移，进而避让显示屏5。
这样，在可折叠电子设备的展开态，第一转动件8可以对显示屏5起到辅助支撑作用，弥补了第一表面41由于设置凹陷部411对显示屏5的支撑强度的影响。
本申请示出的折叠组件的第一种结构，可以在第一表面41上对应于弯曲部51的 至少一侧端部在第一表面41的投影区域设置凹陷部411，以在基体4的厚度方向上，使弯曲部51与凹陷部411之间的第一间隙S1大于弯曲部51与支撑部之间的第二间隙S2。这样，可以通过第一间隙S1在可折叠电子设备轴侧角跌时对显示屏5发生避让，在不影响折叠组件整体强度的情况下，减小可折叠电子设备轴侧角跌时显示屏5与折叠组件的撞击应力，避免了显示屏5的损坏，提升了可折叠电子设备的可靠性。
图16是本申请实施例示出的折叠组件的第二种结构在H2剖面的示意图。
如图16所示，在一些实施例中，凹陷部411可以设置为倾斜曲面，该倾斜曲面可以为连续曲面。里需要说明的是，折叠组件的其他部件可以参照上述实施例进行设置，本申请对此不予赘述。
其中，折叠组件的第一种结构中示出的第一转动件8可以应用于本申请实施例的其他结构中，并根据各种结构进行适应性更改以起到相应的支撑作用，本申请对此不进行限制。
图17是本申请实施例示出的折叠组件的第三种结构示意图。
图17为如图7中的C在相同剖面的剖面视图。如图17所示，在一些实施例中，凹陷部411可以设置为倾斜曲面，该倾斜曲面可以为间断曲面。
这里需要说明的是，折叠组件的其他部件可以参照上述实施例进行设置，本申请对此不予赘述。
图18是本申请实施例示出的折叠组件的第四种结构示意图。如图18所示，在一些实施例中，凹陷部411可以设置为阶梯形。
在一些实施例中，折叠组件可以为轴对称的组件，也可以设置为不对称的组件。
例如，由于可折叠电子设备一侧设置有摄像头，因此，在其发生轴侧角跌时，设置有摄像头的一侧的轴侧角的跌落角度可能与未设置摄像头的一侧的轴侧角的跌落角度有一定偏差，基于此，可以对凹陷部411的轴向长度、径向长度、曲率的大小等进行差别设置，以生成更多的折叠组件的结构。
本申请实施例还包括以上一种折叠组件结构或多种折叠组件结构的组合，本申请实施例对此不予赘述。
本申请实施例可以在第一间隙S1大于第二间隙S2的前提下对凹陷部411进行凹槽、倾斜面、阶梯型等多种形态的选择，并对凹陷部411的轴向长度、径向长度进行适应性设计，进而生成多种折叠组件的结构，以减小可折叠电子设备轴侧角跌时显示屏5与折叠组件的撞击应力，避免了显示屏5的损坏，提升了可折叠电子设备的可靠性。本申请实施例还提供一种可折叠电子设备，该可折叠电子设备包括上述实施例提供的折叠组件，该可折叠电子设备包括但不限于手机、显示器、平板电脑、车载电脑等。本申请实施例对上述可折叠电子设备的具体形式不做特殊限制。
本申请示出的可折叠电子设备，可以在弯曲部51的两端对应的第一表面41的投影区域内设置凹陷部411，以使第一间隙S1大于第二间隙S2，这样，可以通过第一间隙S1在可折叠电子设备轴侧角跌时对显示屏5发生避让，在不影响折叠组件整体强度的情况下，减小可折叠电子设备轴侧角跌时显示屏5与折叠组件的撞击应力，避免了显示屏5的损坏，提升了可折叠电子设备的可靠性。
应理解，在本申请实施例的各种实施例中，各过程的序号的大小并不意味着执行 顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对实施例的实施过程构成任何限定。
本说明书的各个部分均采用递进的方式进行描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点介绍的都是与其他实施例不同之处。尤其，对于装置和系统实施例而言，由于其基本相似于方法实施例，所以描述的比较简单，相关之处参见方法实施例部分的说明即可。
以上所述的具体实施方式，对本申请的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本申请的具体实施方式而已，并不用于限定本申请的保护范围，凡在本申请的技术方案的基础之上，所做的任何修改、等同替换、改进等，均应包括在本申请的保护范围之内。
