背景技术
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
本申请实施例的目的是提供一种电子设备，能够解决电子设备在折叠的过程中较容易损坏柔性屏幕的问题。
为了解决上述技术问题，本申请是这样实现的：
一种电子设备，包括第一壳体、第二壳体、屏幕组件、轴组件和传动件，第一壳体和第二壳体通过轴组件转动配合，传动件套设于轴组件，且传动件可沿轴组件的轴向移动；

屏幕组件的第一段与第一壳体滑动配合，屏幕组件的第二段设置于第二壳体，传动件和屏幕组件的第一段中一者设置有第二抵推部，另一者设置有第二导向面，第二导向面相对于轴组件的轴向倾斜设置，第二抵推部抵接于第二导向面；
在第一壳体相对第二壳体向远离屏幕组件的一侧转动的情况下，第一抵推部沿第一导向面滑动，推动传动件沿轴组件的轴向滑动；传动件通过第二抵推部沿第二导向面滑动，带动屏幕组件的第一段向靠近屏幕组件的第二段的方向移动。
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，第一壳体和第二壳体通过轴组件转动配合，使得第一壳体和第二壳体可以相对转动，实现第一壳体和第二壳体展开和折叠。通过设置第一抵推部和第二导向面，使得电子设备在外折的情况下，即第一壳体相对第二壳体向远离屏幕组件的一侧转动的情况下，使得第一壳体和第二壳体相对转动的过程中可以驱动传动件沿转轴移动，进而通过传动件带动屏幕组件的第二段向靠近屏幕组件的第一段的方向移动，以避免屏幕组件在电子设备折叠的过程中被拉扯而损坏，进而达到保护屏幕组件的目的，解决电子设备折叠过程中屏幕组件容易损坏的问题。

下面结合图1至图14，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3，本申请实施例公开的电子设备包括第一壳体100、第二壳体200、屏幕组件300、轴组件400和传动件500。其中，第一壳体100和第二壳体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。
参照图1和图2，第一壳体100和第二壳体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壳体100和第二壳体200相对转动，实现电子设备折叠或展开。
参照图3和图4，传动件500套设于轴组件400，且传动件500可沿轴组件400的轴向移动。示例性地，传动件500可以与轴组件400滑动配合，进而使得传动件500可以沿轴组件400的轴向移动。
参照图3和图4，第一壳体100和/或第二壳体200设置有第一抵推部210，传动件500具有第一导向面510，第一抵推部210抵接于第一导向面510。可选地，第一抵推部210与第一导向面510滑动配合，以使第一抵推部210可沿第一导向面510滑动。示例性地，第一壳体100和第二壳体200叠合的过程中，第一壳体100和/或第二壳体200带动第一抵推部210沿第一导向面510滑动，进而推动传动件500沿第一转轴410的轴向移动。
参照图9，屏幕组件300包括第一段和第二段，第一段和第二段相连。示例性地，屏幕组件300的第一段设置于第一壳体100，屏幕组件300的第二段设置于第二壳体200。示例性地，第一壳体100可以相对第二壳体200在第一位置和第二位置之间转动。在第一壳体100相对第二壳体200在第一位置的情况下，屏幕组件300的显示面位于同一平面，实现电子设备展开。在第一壳体100相对第二壳体200在第二位置的情况下，第一壳体100远离屏幕组件300的一侧叠置于第二壳体200远离屏幕组件300的一侧，进而实现电子设备外折。
一种可选的实施例中，屏幕组件300的第一段与第一壳体100滑动配合， 以使屏幕组件300的第一段可以沿第一壳体100滑动。参照图3至图8，传动件500与屏幕组件300的第一段相连，以使传动件500可以带动屏幕组件300的第一段沿第一壳体100移动。示例性地，传动件500和屏幕组件300的第一段中一者设置有第二抵推部520，另一者设置有第二导向面310，第二导向面310相对于轴组件400的轴向倾斜设置，且第二抵推部520抵接于第二导向面310。示例性地，第二抵推部520与第二导向面310滑动配合，以使第二抵推部520可以沿第二导向面310滑动。示例性地，在第一壳体100相对第二壳体200向设置有屏幕组件300的一侧转动的情况下，第一壳体100和第二壳体200通过第一抵推部210沿第一导向面510滑动，并推动传动件500沿轴组件400的轴向滑动。传动件500通过第二抵推部520沿第二导向面310滑动带动屏幕组件300的第一段向靠近屏幕组件300的第二段的方向移动。
需要说明的是，本申请说明书中所述的电子设备在外折是指，电子设备折叠后，屏幕组件300位于第一壳体100和第二壳体200中靠近外表面的一侧。上述实施例中所述的电子设备，可以在电子设备外折的过程中，通过传动件500带动屏幕组件300中的第一段向靠近屏幕组件300的第二段移动，进而避免电子设备在外折的过程中屏幕组件300受到拉扯，进而可以解决屏幕组件300在电子设备外折的过程中容易受到拉扯而损坏的问题。
参照图3至图5，第一导向面510可以围绕轴组件400设置，且第一导向面510向轴组件400的轴向倾斜。示例性地，第一导向面510可以为围绕轴组件400的螺旋倾斜面。可选的，第一导向面510设置于传动件500靠近第一抵推部210一侧的端部。另一种可选的实施例中，传动件500周向的侧壁上设置有螺旋状凹槽或凸起，以通过螺旋状凹槽的内侧壁或者是凸起的侧壁形成第一导向面510。
参照图7，一种可选的实施例中，传动件500套设于轴组件400，传动件500的一端设置有第二抵推部520，屏幕组件300的第一段可以设置有第二导向面310。示例性地，传动件500的一端设置有圆形孔或圆形凹槽。屏幕组 件300具有凸向传动件500的圆形孔或圆形凹槽的凸起结构，第二导向面310设置于该凸起结构上，进而使得传动件500靠近该凸起结构的一端可以沿第二导向面310滑动。在电子设备折叠的过程中，第一抵推部210随第一壳体100和/或第二壳体200转动，进而推动传动件500向靠近第二导向面310的方向运动，进而使得第二导向面310在传动件500的作用下向靠近第一转轴410的方向移动，以带动屏幕组件300的第一段向靠近屏幕组件300的第二段的方向移动。
另一种可选的实施例中，第二导向面310为设置于传动件500端部的锥形孔或锥形槽，且锥形孔或锥形槽的内壁侧壁相对于轴组件400倾斜设置。第二抵推部520为设置于屏幕组件300上的凸起结构，且该凸起结构凸向锥形孔或锥形槽，且该凸起结构至少部分位于锥形孔或锥形槽内，以使第二抵推部520可以抵接于锥形孔或锥形槽内侧壁。在传动件500沿轴组件400的轴向滑动的过程中，第二抵推部可以沿锥形孔或锥形槽的内侧壁在轴组件400的轴向滑动，以能带动屏幕组件300的第一段向靠近屏幕组件300中的第二段移动。
一种可选的实施例中，传动件500包括套筒540和第一传动块550。示例性地，套筒540套设于轴组件400，且第一导向面510设置于套筒540。第一传动块550的第一端与传动件500相连，且第一传动块550相对于套筒540可绕轴组件400转动。第一传动块550的第二端与屏幕组件300的第一段通过第二抵推部520和第二导向面310相连。在电子设备折叠的过程中，即第一壳体100相对第二壳体200向远离屏幕组件300的一侧转动的情况下，第一抵推部210带动套筒540沿轴组件400的轴向移动，且套筒540通过第一传动块550带动屏幕组件300的第一段相对于第一壳体100移动，进而可以在电子设备外折的过程中，通过屏幕组件300的第一段相对第一壳体100滑动，以避免屏幕组件300在电子设备弯折处受到拉力过大而损坏。
上述实施例中，第一传动块550可以将套筒540沿轴组件400的轴向移动转化为屏幕组件300的第一段向靠近屏幕组件300的第二段的方向移动， 进而可以在电子设备折叠过程中避免屏幕组件300受到拉。并且，可以通过设置第一传动块550可以避免屏幕组件300的第一段相对第一壳体100移动的位移大小受到套筒540直径的影响，进而使得电子设备可以根据需要缩小第一传动块550的直径，以便于降低电子设备的厚度。
参照图3至图8，轴组件400可以包括第一转轴410和第二转轴420。第一转轴410和第二转轴420可以平行设置，其中，第一转轴410设置于第一壳体100，且第一壳体100通过第一转轴410与传动件500转动配合，第二转轴420设置于第二壳体200，且第二壳体200通过第二转轴420与传动件500转动配合。示例性地，传动件500可以具有两个相互平行的安装孔，第一转轴410和第二转轴420可以分别与传动件500上的两个安装孔间隙配合，以使第一转轴410和第二转轴420可以分别相对于传动件500转动，且传动件500可以沿第一转轴410和第二转轴420滑动。该方案中，第一转轴410和第二转轴420平行且间隔设置，进而使第一壳体100和第二壳体200分为围绕两个相互平行的轴线转动，进而使得第一壳体100和第二壳体200相互避让的空间增加，以避免第一壳体100和第二壳体200在电子设备展开或折叠的过程中相互干扰。
一种可选的实施例中，第一转轴410与第二转轴420之间的间距为第一距离，第一转轴410距离第一壳体100中远离屏幕组件300的第一段的一侧的距离为第二距离。第二转轴420距离第二壳体200中远离屏幕组件300的第二段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，第一壳体100和第二壳体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。
参照图3至图4，轴组件400还可以包括中轴430，中轴430具有第一安装孔和第二安装孔。中轴430通过第一安装孔与第一转轴410转动配合，中轴430通过第二安装孔与第二转轴420转动配合。传动件500套设于中轴430，且传动件500与中轴430滑动配合。传动件500通过中轴430与第一转轴410和第二转轴420转动配合，可以减小传动件500沿第一转轴410轴线移动的 阻力。
需要说明的是，第一壳体100和第二壳体200相对转动的过程中，第一转轴410和第二转轴420受到第一壳体100和第二壳体200的作用力使得第一转轴410和第二转轴420具有相互远离或靠近的运动趋势。在传动件500上开设分别用于安装第一转轴410和第二转轴420的第一安装孔和第二安装孔的情况下，由于第一壳体100和第二壳体200的作用，会使第一转轴410与第一安装孔的孔壁之间的挤压力增加，第二转轴420与第二安装孔的孔壁之间的挤压力增加，进而导致第一转轴410与第一安装孔的孔壁之间的摩擦力增加，第二转轴420与第二安装孔内的摩擦力增加。因此，传动件500直接开设与第一转轴410装配的第一安装孔和与第二转轴420装配的第二安装孔，使得第一转轴410与第一安装孔之间的摩擦力不仅会阻碍第一转轴410相对于传动件500转动，还会阻碍传动件500沿第一转轴410的轴向移动。同理，第二转轴420与第二安装孔之间的摩擦力不仅会阻碍第二转轴420相对于传动件500转动，还会阻碍传动件500沿第二转轴420的轴向移动。上述实施例中，通过设置中轴430，并将第一安装孔和第二安装孔设置于中轴430，传动件500与中轴430滑动配合，进而可以避免第一转轴410和第二转轴420受力影响传动件500沿轴组件400轴向滑动的阻力。参照图3至图5，第一转轴410与第一安装孔之间的摩擦力增加，只会增加第一转轴410相对传动件500转动的阻力，而不会增加传动件500沿中轴430移动的阻力；第二转轴420与第二安装孔之间的摩擦力增加，只会增加第二转轴420相对传动件500转动的阻力，而不会增加传动件500沿中轴430移动的阻力。因此，上述实施例通过设置中轴430可以传动件500沿轴组件400的轴向移动的阻力。
参照图5，第一导向面510围绕中轴430设置，且第一导向面510向中轴430的轴向倾斜。示例性地，传动件500上可以设置有导轨或导槽，以通过导轨或导槽形成围绕中轴430设置的第一导向面510。在电子设备折叠的过程中，第一抵推部210可以沿第一导向面510滑动，进而推动传动件500 沿第一转轴410的轴向移动。参照图5，第一导向面510可以为设置于传动件500外周的螺旋状导向面。示例性地，第一抵推部210可以为设置于第一壳体100和/或第二壳体200的凸块或凸柱。示例性地，第一抵推部210与第一导向面510接触的一端设置为弧形面，以减小第一抵推部210沿第一导向面510滑动的阻力。
参照图3、图7和图8，中轴430和传动件500中，一者设置有限位槽431，且限位槽431沿第一转轴410轴向设置，另一者设置有限位凸起530，限位凸起530至少部分内嵌于限位槽431，且限位凸起530与限位槽431滑动配合。设置限位槽431和限位凸起530，不仅可以使传动件500沿中轴430滑动，还可以避免传动件500与中轴430相对转动。通过限定传动件500相对中轴430转动，可以确保传动件500在第一抵推部210的作用下可以沿第一转轴410的轴向移动。
另一种可选的实施例中，中轴430可以设置为方轴，传动件500设置有方形孔，以使传动件500可以通过方形孔与中轴430滑动配合，并限定传动件500与中轴430相对转动的自由度。限定传动件500相对于中轴430转动的方式有很多，例如：中轴430设置为六棱柱，传动件500设置有与中轴430滑动配合的六棱孔。为此，本申请不对限定中轴430与传动件500转动的结构做具体限定。
参照图3，一种可选的实施例中，第一传动块550与第一壳体100滑动配合，第一传动块550的第一端套设于第一转轴410，且第一传动块550与第一转轴410滑动配合，在第一壳体100和第二壳体200折叠的过程中，第一壳体100带动第一传动块550相对第一转轴410转动，套筒540带动第一传动块550沿第一转轴410的轴向移动。示例性地，第一壳体100上设置滑槽，第一传动块550至少部分位于滑槽内，进而使得第一传动块550可以沿滑槽滑动。该实施例中，通过第一传动块550沿第一壳体100滑动，使得位于第一传动块550与屏幕组件300的第一段相互作用，进而带动屏幕组件300的第一段向屏幕组件300的第二段移动。示例性地，第一传动块550可以与 套筒540抵触相连和/或转动配合。
参照图7，一种可选的实施例中，第一传动块550上设置有转动部551，转动部551与第一壳体100转动配合，在第一壳体100和第二壳体200折叠的过程中，套筒540带动第一传动块550相对于第一壳体100转动。示例性地，第一传动块550与套筒540之间的连接处距离转动部551的距离为第一力臂，转动部551与屏幕组件300的第一段的连接处之间的距离为第二力臂，第一力臂大于第二力臂，以减小电子设备折叠过程中的阻力。示例性地，转动部551位于第一传动块550的第一端和第一传动块550的第二端之间。
参照图3、图9、图12和图13，一种可选的实施例中，屏幕组件300的第一段设置有导向块350，导向块350位于屏幕组件300中远离显示面的一侧。示例性地，第二导向面310可以设置于导向块350，第二抵推部520可以设置于第一传动块550，以使导向块350可以通过第二导向面310和第二抵推部520与第一传动块550相连，以使第一传动块550可以带动导向块350和屏幕组件300中的第一段向靠近屏幕组件300的第二段的方向移动。
参照图12和图13，屏幕组件300还包括第一固定块370，第一固定块370固定设置于屏幕组件300的第一段远离显示面的一侧。进一步地，导向块350可以通过第一固定块370与屏幕组件300固定相连。当然，导向块350还可以通过粘贴的方式固定于屏幕组件300的第一段远离显示面的一侧。
参照图1至图3，屏幕组件300的第二段与第二壳体200滑动配合，传动件500和屏幕组件300的第一段中一者设置有第三抵推部560，另一者设置有第三导向面360，第三导向面360相对于轴组件400的轴向倾斜设置，且第三抵推部560与第三导向面360滑动配合。在第一壳体100和第二壳体200折叠的过程中，传动件500带动屏幕组件300的第二段向靠近屏幕组件300第一段的方向移动。示例性地，第三导向面360可以设置于传动件500或屏幕组件300上，以使第三抵推部560在沿第三导向面360滑动的过程中，可以带动屏幕组件300的第二段向靠近屏幕组件300的第一段的方向移动。
