技术领域
本申请属于通信技术领域，具体涉及一种电子设备。
背景技术
随着通信技术的发展，电子设备的显示屏尺寸越来越大，而较大的显示屏不仅能够提高电子设备的美观性，还能为用户带来较好的视觉冲击，以提升电子设备的使用体验。
然而，随着显示屏尺寸的增大，电子设备的整体尺寸随之变大，进而不便于用户携带。为解决这一问题，目前市面上出现了折叠屏电子设备，该电子设备的显示屏为柔性显示屏，因此可以通过电子设备的折叠和展开来改变显示区域的大小，从而既能够获得较大的显示区域，又可以通过折叠电子设备的方式减小其尺寸，以便于用户携带。
然而，受电子设备的折弯半径的影响，在折叠或展开电子设备的过程中，柔性显示屏容易被过度挤压而褶皱分层，或者被过度拉扯而断裂，因此此种电子设备存在其柔性显示屏寿命短的问题。
发明内容
本申请实施例的目的是提供一种电子设备，能够解决柔性显示屏寿命短的问题。
为了解决上述技术问题，本申请是这样实现的：
本申请实施例提供了一种电子设备，其包括第一设备主体、第二设备主 体、转动机构和柔性显示屏，所述柔性显示屏包括第一显示屏、第二显示屏和第三显示屏；
所述第一设备主体通过所述转动机构与所述第二设备主体转动相连；
所述第一显示屏通过所述第三显示屏与所述第二显示屏相连；
所述第一设备主体与所述第一显示屏相连，所述第二设备主体与所述第二显示屏相连；
所述转动机构包括转轴和传动装置，所述转轴通过所述传动装置与所述第一设备主体和所述第二设备主体中的至少一者相连；
所述第一设备主体与所述第二设备主体可相对转动以使所述电子设备在折叠状态与展开状态之间切换，在所述电子设备自所述折叠状态向所述展开状态切换的情况下，所述转轴通过所述传动装置驱动所述第一设备主体和所述第二设备主体中的至少一者远离所述转轴；在所述电子设备自所述展开状态向所述折叠状态切换的情况下，所述转轴通过所述传动装置驱动所述第一设备主体和所述第二设备主体中的至少一者靠近所述转轴。
本申请实施例中，在电子设备自折叠状态向展开状态切换的情况下，转轴可以通过传动装置驱动第一设备主体和第二设备主体中的至少一者远离转轴，从而使得第一设备主体和第二设备主体对柔性显示屏的支撑长度变大，以防止柔性显示屏的第三显示屏被挤压而褶皱分层；在电子设备自展开状态向折叠状态切换的情况下，转轴通过传动装置驱动第一设备主体和第二设备主体中的至少一者靠近转轴，从而使得第一设备主体和第二设备主体对柔性显示屏的支撑长度变小，以防止柔性显示屏的第三显示屏被过度拉扯而断裂。可见，第一设备主体和第二设备主体可伴随电子设备的折叠或者展开而相对于转轴运动，从而使得柔性显示屏不因电子设备的折叠或者展开而损坏，因此柔性显示屏的寿命更长。

具体实施方式

下面结合附图，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。
参考图1至图12，本申请实施例公开一种电子设备，其包括第一设备主体110、第二设备主体120、转动机构300和柔性显示屏400。
第一设备主体110和第二设备主体120可以作为电子设备的基础部分，从而为柔性显示屏400、电路板、电池等部件提供安装基础。第一设备主体110和第二设备主体120均可以包括边框、与边框相连的主板上盖等部件。第一设备主体110通过转动机构300与第二设备主体120转动相连，第一设备主体110与第二设备主体120可相对转动以使电子设备在折叠状态与展开状态之间切换，换言之，折叠或展开电子设备的过程中，第一设备主体110与第二设备主体120可相对转动，当电子设备处于展开状态时，柔性显示屏400的显示区域较大，从而满足用户对大显示屏的需求；当电子设备处于折叠状态时电子设备的整体尺寸较小，从而便于用户携带及握持电子设备。
柔性显示屏400包括第一显示屏410、第二显示屏420和第三显示屏430， 第一显示屏410通过第三显示屏430与第二显示屏420相连，使得三者可以固定拼接成完整的显示区域，当然，第一显示屏410、第二显示屏420和第三显示屏430也可以独立显示。第一设备主体110可以通过粘接等方式与第一显示屏410相连，第二设备主体120可以通过粘接等方式与第二显示屏420相连。因此，折叠或展开电子设备的过程中，在第一设备主体110和第二设备主体120的带动下，第一显示屏410与第二显示屏420可相对转动，而第三显示屏430则可以变形，以适应第一显示屏410与第二显示屏420之间的角度变化。
柔性显示屏400可以为外折叠显示屏，即，在电子设备处于折叠状态的情况下，第一设备主体110和第二设备主体120均位于第一显示屏410和第二显示屏420之间，此时第一设备主体110和第二设备主体120位于柔性显示屏400所围成的空间内。柔性显示屏400也可以为内折叠显示屏，即，在电子设备处于折叠状态的情况下，第一显示屏410和第二显示屏420均位于第一设备主体110和第二设备主体120之间，此时第一显示屏410和第二显示屏420位于第一设备主体110和第二设备主体120之间的空间内。相对而言，柔性显示屏400为内折叠显示屏时，在电子设备处于折叠状态的情况下，柔性显示屏400容易因第一设备主体110和第二设备主体120的挤压而出现折痕，同时外部环境中的灰尘等颗粒物容易因柔性显示屏400无法完全贴合而进入电子设备或柔性显示屏400内；而柔性显示屏400为外折叠显示屏时，第一设备主体110和第二设备主体120基本不会挤压柔性显示屏400，因此柔性显示屏400更不容易出现折痕，同时外部环境中的灰尘等颗粒物不容易因柔性显示屏400无法完全贴合而进入电子设备或柔性显示屏400内。此外，外折叠屏始终裸露，因此无论电子设备处于折叠状态还是展开状态，都可以通过柔性显示屏400进行显示，从而更好地满足用户的显示需求。
转动机构300包括转轴和传动装置310，转轴通过传动装置310与第一设备主体110和第二设备主体120中的至少一者相连。折叠或展开电子设备 的过程中，第一设备主体110和第二设备主体120可以绕转轴转动。在折叠或展开电子设备的过程中，传动装置310可以将转轴输出的作用力传递至第一设备主体110和第二设备主体120中的至少一者，从而使得第一设备主体110和第二设备主体120中的至少一者可以在折叠操作或展开操作的触发下运动。第一设备主体110和第二设备主体120中的至少一者可以定义为目标设备主体，在电子设备折叠或展开的过程中，目标设备主体相对于转轴的距离可以动态变化，且目标设备主体与转轴之间的距离可以定义为第一距离，由于该第一距离随着第一设备主体110和第二设备主体120之间的夹角变化而变化，而这里的夹角变化又会带来柔性显示屏400的弯折角度的变化，因此第一距离与柔性显示屏400的弯折角度存在对应关系。
传动装置310可以仅设置一个，并且转轴通过该传动装置310仅与第一设备主体110或第二设备主体120传动相连；或者，传动装置310设置为至少两个，转轴通过至少一个传动装置310与第一设备主体110传动相连，同时，转轴通过另外的至少一个传动装置310与第二设备主体120传动相连。此外，转轴可以通过至少两个传动装置310同时与第一设备主体110传动相连，转轴也可以通过至少两个传动装置310同时与第二设备主体120传动相连，从而提升连接可靠性。当传动装置310的数量为至少两个时，各传动装置310的具体结构可以相同，也可以不同，本申请实施例对此不作限制。
在电子设备自折叠状态向展开状态切换的情况下，转轴通过传动装置310驱动第一设备主体110和第二设备主体120中的至少一者远离转轴，从而使得第一设备主体110和第二设备主体120对柔性显示屏400的支撑长度变大，以防止柔性显示屏400的第三显示屏430被挤压而褶皱分层。在电子设备自展开状态向折叠状态切换的情况下，转轴通过传动装置310驱动第一设备主体110和第二设备主体120中的至少一者靠近转轴，从而使得第一设备主体110和第二设备主体120对柔性显示屏400的支撑长度变小，以防止柔性显示屏400的第三显示屏430被过度拉扯而断裂。可见，第一设备主体 110和第二设备主体120可伴随电子设备的折叠或者展开而相对于转轴运动，从而使得柔性显示屏400不因电子设备的折叠或者展开而损坏，因此柔性显示屏400的寿命更长。
可选地，转轴可以仅设置一个，该转轴可以仅通过传动装置310与第一设备主体110或第二设备主体120相连，但如此设置会导致第一设备主体110或第二设备主体120的运动行程较长，且在折叠或者展开电子设备的过程中，整个电子设备容易出现重心不稳的情况。因此，其他实施例中，转轴的数量可以为至少两个，其中包括第一轴210和第二轴220，第一轴210和第二轴220可以相互平行，第一轴210可以通过至少一个传动装置310与第一设备主体110相连，第二轴220可以通过至少一个传动装置310与第二设备主体120相连。在电子设备自折叠状态向展开状态切换的情况下，第一轴210通过传动装置310驱动第一设备主体110远离转轴，第二轴220通过传动装置310驱动第二设备主体120远离转轴。在电子设备自展开状态向折叠状态切换的情况下，第一轴210通过传动装置310驱动第一设备主体110靠近转轴，第二轴220通过传动装置310驱动第二设备主体120靠近转轴。
进一步地，转动机构300还包括转轴支架350，转轴支架350设有第一穿孔和第二穿孔，第一轴210的一端穿过第一穿孔，第二轴220的一端穿过第二穿孔，换言之，第一轴210可以通过转轴支架350与第二轴220相连。可选地，转轴支架350设有弧形支撑面351，在电子设备处于折叠状态的情况下，弧形支撑面351朝向第三显示屏430。在电子设备处于折叠状态的情况下，弧形支撑面351可以与第三显示屏430相接触，从而支撑第三显示屏430；或者，弧形支撑面351与第三显示屏430之间也可以具有较小的间隙，当第三显示屏430受压时，第三显示屏430与弧形支撑面351相接触，从而支撑第三显示屏430。此时，转轴支架350一方面可以连接第一轴210和第二轴220，另一方面可以在适当的时机支撑第三显示屏430，从而提升第三显示屏430的平整度，便于用户实施触控操作，并保护第三显示屏430。
当柔性显示屏400为内折叠显示屏时，转轴支架350所设置的弧形支撑面351可以是内凹面，该内凹面沿远离第三显示屏430的方向凹陷，从而增大弧形支撑面351对第三显示屏430的支撑面积。当柔性显示屏400为外折叠显示屏时，转轴支架350所设置的弧形支撑面351可以是外凸面，该外凸面沿靠近第三显示屏430的方向凸出，从而增大弧形支撑面351对第三显示屏430的支撑面积。
在折叠或展开电子设备的过程中，第一轴210和第二轴220同时转动，为了提升两者转动的同步性，可以在两者的端部设置橡胶等材料制成的弹性件，通过弹性件之间的摩擦实现第一轴210和第二轴220之间的同步转动。但是，由于弹性件之间容易打滑，因此第一轴210和第二轴220转动时的同步性较差。为了解决该问题，可选的实施例中，转动机构300还包括支撑板340，该支撑板340的数量为至少两个，至少一个支撑板340与第一轴210相连，另外的至少一个支撑板340与第二轴220相连，与第一轴210相连的支撑板340包括第一齿轮部341，与第二轴220相连的支撑板340包括第二齿轮部342，第一齿轮部341套设于第一轴210，第二齿轮部342套设于第二轴220，第一齿轮部341与第二齿轮部342相啮合。与第一轴210相连的支撑板340还可以包括与第一设备主体110滑动连接的部分，与第二轴220相连的支撑板340还可以包括与第二设备主体120滑动连接的部分，在折叠或展开电子设备的过程中，通过第一齿轮部341与第二齿轮部342相啮合，第一设备主体110与第二设备主体120可相对转动，并且第一齿轮部341和第二齿轮部342分别带动第一轴210和第二轴220同步转动。由于齿啮合的传动方式可靠性更高，因此该实施例可以提升第一轴210和第二轴220转动时的同步性。并且，第一齿轮部341与第二齿轮部342之间的啮合可以在电子设备折叠或展开的过程中形成一定的阻尼感，防止第一设备主体110和第二设备主体120相对转动的速度过快而出现碰撞等问题。第一齿轮部341与第二齿轮部342之间的阻尼力可以进行优化，从而使得用户向电子设备施加作用力 时可以相对容易地折叠或展开电子设备，同时，当用户想要使电子设备停留在任意角度而撤去作用力时，第一设备主体110和第二设备主体120可以保持在目标位置。
可选地，转动机构300还包括第一移动件320和第二移动件330，转轴通过传动装置310与第一移动件320相连，转轴通过传动装置310与第二移动件330相连，第一移动件320与第一设备主体110相连，第二移动件330与第二设备主体120相连。第一移动件320可以通过螺钉等连接结构与第一设备主体110固定连接，第二移动件330同样可以通过螺钉等连接结构与第二设备主体120固定连接。第一移动件320和第二移动件330均可以采用长条形结构，两者可以平行于转轴，从而便于电子设备的布局设计，同时，第一移动件320与第一设备主体110的连接面积更大，第二移动件330与第二设备主体120的连接面积更大，从而可以通过第一移动件320和第二移动件330可靠地驱动第一设备主体110和第二设备主体120运动。在电子设备自折叠状态向展开状态切换的情况下，转轴通过传动装置310驱动第一移动件320和第二移动件330远离转轴；在电子设备自展开状态向折叠状态切换的情况下，转轴通过传动装置310驱动第一移动件320和第二移动件330靠近转轴。
当转动机构300还包括支撑板340时，支撑板340与转轴相连，支撑板340可以作为传动装置310的设置基础，从而便于实现传动装置310的安装。传动装置310可以将转轴的转动转化为第一设备主体110和/或第二设备主体120的移动，可实现该目的的方案有很多种，例如传动装置310可以包括齿轮齿条机构等。可选的实施例中，传动装置310可以包括丝杠311，丝杠311可转动地设置于支撑板340，第一移动件320或第二移动件330上设置有螺纹孔，丝杠311与螺纹孔螺纹传动配合。即，第一移动件320可以设置螺纹孔，与第一移动件320相连的丝杠311与该螺纹孔螺纹传动配合，第二移动件330可以设置螺纹孔，与第二移动件330相连的丝杠311与该螺纹孔螺纹 传动配合，可选的实施例中，可以仅在第一移动件320或第二移动件330上设置螺纹孔，也可以在第一移动件320和第二移动件330上都设置螺纹孔，不同的丝杠311与不同的螺纹孔螺纹传动配合。通过丝杠311和螺纹孔传动的方式具有可靠性高、结构简单、占用空间小等特点。
可选地，丝杠311可垂直于转轴，从而使得第一移动件320的移动方向与第一设备主体110的移动方向一致，第二移动件330的移动方向和第二设备主体120的移动方向一致，无需额外设置结构进行传动方向的转化，从而简化电子设备的结构。
第一移动件320可以采用一体式结构，但第一移动件320设置螺纹孔的部分容易损坏，如果采用一体式结构，一旦螺纹孔出现滑丝等问题，就需要整体更换第一移动件320，导致电子设备的维护成本较高。因此，在其他实施例中，第一移动件320可以包括分体设置的连接件和滑块304，该连接件与第一设备主体110相连，滑块304与该连接件可拆卸连接，滑块304与支撑板340滑动连接，滑块304上设置有螺纹孔。当第一移动件320的滑块304所设置的螺纹孔出现滑丝等问题时，只需要更换第一移动件320的滑块304即可，连接件则可以不更换，因此该实施例可以降低电子设备的维护成本。
同理地，第二移动件330可以采用一体式结构，但第二移动件330设置螺纹孔的部分容易损坏，如果采用一体式结构，一旦螺纹孔出现滑丝等问题，就需要整体更换第二移动件330，导致电子设备的维护成本较高。因此，在其他实施例中，第二移动件330包括分体设置的连接件和滑块304，该连接件与第二设备主体120相连，滑块304与该连接件可拆卸连接，滑块304与支撑板340滑动连接，滑块304上设置有螺纹孔。当第二移动件330的滑块304所设置的螺纹孔出现滑丝等问题时，只需要更换第二移动件330的滑块304即可，连接件则可以不更换，因此该实施例可以降低电子设备的维护成本。
支撑板340可以用于安装丝杠311，可选地，支撑板340设有第一安装孔345、第二安装孔346和容纳孔347，容纳孔347位于第一安装孔345和第 二安装孔346之间，丝杠311与第一安装孔345和第二安装孔346转动配合，滑块304与容纳孔347滑动配合。可选地，第一安装孔345和第二安装孔346可以为圆孔，容纳孔347可以为矩形孔，容纳孔347可以是盲孔，也可以是通孔。第一安装孔345和第二安装孔346可与丝杠311的光滑段配合，从而使得丝杠311可以相对于支撑板340转动，同时支撑板340可以限制丝杠311的位置，并且，由于第一安装孔345和第二安装孔346均可与丝杠311配合，因此支撑板340与丝杠311的连接更加可靠。容纳孔347首先可以与滑块304滑动配合，从而限制滑块304的转动，使得滑块304在丝杠311的作用下只能移动不能转动；其次，容纳孔347可以避让滑块304，即滑块304可以利用支撑板340所占用的空间来设置，使得滑块304额外占用的空间更小，更便于电子设备的结构设计。
可选地，丝杠311可以通过轴承360与第一安装孔345和第二安装孔346连接，从而缓解丝杠311转动所造成的磨损。
支撑板340可以为一体式结构，由于支撑板340包括第一齿轮部341或第二齿轮部342，同时包括用于与丝杠311连接的部分，一旦第一齿轮部341或第二齿轮部342的磨损量超出可接受范围，就需要整体更换支撑板340，导致电子设备的维护成本较高。因此，可选地，与第一设备主体110相连的支撑板340可以包括第一齿轮部341和第一安装部343，第一安装部343与丝杠311连接，第一齿轮部341和第一安装部343分体设置，两者可以通过螺钉370等结构可拆卸相连，当第一齿轮部341的磨损量超出可接受范围时，仅更换第一齿轮部341即可。
同理地，与第二设备主体120相连的支撑板340可以包括第二齿轮部342和第二安装部344，第二安装部344与丝杠311连接，第二齿轮部342和第二安装部344分体设置，两者可以通过螺钉370等结构可拆卸相连，当第二齿轮部342的磨损量超出可接受范围时，仅更换第二齿轮部342即可。
滑块304和连接件可以通过螺钉等结构可拆卸固定，也可以通过卡接、 插接等方式可拆卸固定。一种可选的实施例中，滑块304设有插槽305，连接件设有插装凸部306，插装凸部306与插槽305配合，从而将滑块304和连接件连接在一起，以实现滑块304与连接件之间的动力传递。当然，插槽305和插装凸部306也可以对调设置，即滑块304设有插装凸部306，连接件设有插槽305，插装凸部306与插槽305配合。通过插装凸部306和插槽305配合的方式实现滑块304和连接件的连接时，不需要借助螺钉等紧固件，因此可以简化电子设备的结构，同时便于滑块304和连接件之间的连接。
可选地，插装凸部306的插装方向可以是第一设备主体110或第二设备主体120的厚度方向，插槽305可以是锥形槽，插装凸部306可以是与插槽305的形状相适配的锥形凸部，即，在连接件向滑块304延伸的方向上，插槽305的横截面面积逐渐增大，插装凸部306的横截面面积同样逐渐增大，这里的横截面指的是垂直于转轴的截面。通过锥形的插槽305和锥形的插装凸部306相配合，可以在多个方向上限制插装凸部306和插槽305的相对位移，从而使得滑块304和连接件更可靠地连接在一起。
滑块304可以仅单侧设置插槽305或插装凸部306，连接滑块304和连接件时，需要注意滑块304的安装方向，以保证插槽305和插装凸部306能够配合，因此该结构会限制滑块304的安装方向，不便于电子设备的组装。因此，为了便于组装电子设备，可以使滑块304的两侧均设有插槽305，或者使滑块304的两侧均设有插装凸部306，组装电子设备时，滑块304任意一侧的插槽305或插装凸部306都可以与连接件上的对应结构相配合，因此不需要特意摆放滑块304，以达到便于组装电子设备的目的。此外，当滑块304的其中一侧所设置的插槽305或者插装凸部306损坏而无法与连接件配合时，只需要更换滑块304的安装方向，就可以通过滑块304另一侧的插槽305或者插装凸部306实现滑块304与连接件的连接，而不需要整体更换滑块304，因此该实施例还可以降低电子设备的维护成本。
由于滑块304需要环绕丝杠311，因此滑块304的厚度较大，而连接件 的主要作用是连接第一设备主体110或第二设备主体120，如果连接件的厚度与滑块304的厚度相等，甚至连接件的厚度大于滑块304的厚度，那么连接件所占用的空间就会比较大，造成电子设备内空间的浪费。基于此，可以使滑块304的厚度大于连接件的厚度，如此设置既能保证滑块304与丝杠311有足够大的配合面积，又不影响连接件与第一设备主体110或第二设备主体120之间的连接，同时可以减小连接件占用的空间，使得电子设备有更多的空间来设置其他部件。
可选的实施例中，连接件可以包括主体部301以及设置于主体部301两端的第一连接部302和第二连接部303。主体部301可以与第一设备主体110或第二设备主体120相连，可选地，主体部301可以通过螺钉等结构与第一设备主体110或第二设备主体120相连。第一连接部302和第二连接部303分别与不同的滑块304相连，从而使得主体部301的两端均可以与传动装置310相连，以使转轴更可靠地驱动第一设备主体110和第二设备主体120中的至少一者运动。
如上所述，主体部301主要用于连接第一设备主体110或第二设备主体120，因此主体部301的厚度对其与第一设备主体110或第二设备主体120之间的连接强度具有较大的影响，与此同时，第一连接部302和第二连接部303主要用于传递作用力，因此两者的厚度只要能够满足作用力的传递要求即可。据此，可以使主体部301的厚度大于第一连接部302和第二连接部303的厚度，从而提升主体部301与第一设备主体110或第二设备主体120之间的连接强度，同时适当减小第一连接部302和第二连接部303的厚度，这样设置既能满足传递作用力的需求，又可以减小连接件占用的空间，以便于其他零部件的布局。
一种可选的实施例中，第一设备主体110设有第一支撑部101和第二支撑部102，第一支撑部101与第一连接部302相连，第二支撑部102与第二连接部303相连，即第一支撑部101可以支撑第一连接部302，第二支撑部 102可以支撑第二连接部303。相比于第一连接部302和第二连接部303悬臂设置的方案，增加第一支撑部101和第二支撑部102后，连接件的两端分别被第一支撑部101和第二支撑部102支撑，从而使得第一连接部302和第二连接部303不容易弯折，从而提升两者的结构强度，使得连接件更可靠地传递作用力。
当主体部301的厚度大于第一连接部302和第二连接部303的厚度时，主体部301凸出于第一连接部302和第二连接部303的部分可以背离第一支撑部101和第二支撑部102，此时主体部301与第一设备主体110之间的间隙更大，不利于主体部301与第一设备主体110的连接。因此，另一可选的实施例中，主体部301凸出于第一连接部302和第二连接部303的部分可以朝向第一支撑部101和第二支撑部102，换言之，在转轴的轴线方向上，主体部301的至少一部分位于第一支撑部101和第二支撑部102之间。采用此种结构后，主体部301与第一设备主体110之间的间隙更小，因此有利于主体部301与第一设备主体110的连接，与此同时，主体部301可以利用第一支撑部101和第二支撑部102之间的一部分空间，因此连接件额外占用的空间更小，更便于其他零部件的布局。
进一步地，第一支撑部101和第二支撑部102中的至少一者设有第一滑槽103，第一设备主体110的侧壁设有第二滑槽104，支撑板340的两侧分别与第一滑槽103和第二滑槽104滑动配合。可选地，第一支撑部101和第二支撑部102采用条形结构，两者可沿垂直于转轴的方向延伸。该实施例充分利用第一支撑部101和第二支撑部102以形成导向结构，该导向结构可以为支撑板340的运动提供导向，从而使得第一设备主体110和第二设备主体120的相对转动更加顺畅，同时可以在电子设备折叠或展开的过程中形成一定的阻尼感，防止第一设备主体110和第二设备主体120相对转动的速度过快而出现碰撞等问题。
需要说明的是，上文描述了第一设备主体110设有第一支撑部101和第 二支撑部102的方案，在其他实施例中，也可以在第二设备主体120上设置第一支撑部101和第二支撑部102，该第一支撑部101可支撑与第二设备主体120相连的连接件的第一连接部302，第二支撑部102可支撑与第二设备主体120相连的连接件的第二连接部303，并且该第一支撑部101、第二支撑部102以及与第二设备主体120相连的连接件的结构同样可以采用上文所述的各可选方案，为了文本简洁，本文不再赘述。当然，第一设备主体110和第二设备主体120可以同时设置第一支撑部101和第二支撑部102。
转轴与丝杠311之间的传动可以通过蜗轮蜗杆机构实现，也可以通过锥齿轮实现，相对而言，锥齿轮的传动效率更高，因此为了提升传动效率，本申请实施例中的传动装置310还包括第一锥齿轮315和第二锥齿轮316，第一锥齿轮315套设于转轴，第二锥齿轮316套设于丝杠311，第一锥齿轮315与第二锥齿轮316相啮合。通过调整第一锥齿轮315和第二锥齿轮316的传动比，可以调整第一设备主体110和第二设备主体120的移动行程，从而使得该移动行程更好地与电子设备的姿态相匹配。
当转动机构300还包括转轴支架350时，转轴支架350可以采用一体式结构，但考虑到转轴需要同时套设第一齿轮部341、第二齿轮部342以及第一锥齿轮315，并且第一齿轮部341和第二齿轮部342套设于转轴的端部，第一锥齿轮315与第一齿轮部341、第二齿轮部342之间则具有间隔，因此为了尽量增加转轴支架350的尺寸以支撑转轴及第三显示屏430，可以将转轴支架350设置为多个，各转轴支架350可以沿着转轴的轴线方向间隔排布，第一锥齿轮315可以位于相邻的转轴支架350之间。
本申请实施例公开的电子设备可以是智能手机、平板电脑、电子书阅读器、可穿戴设备(例如智能手表)、电子游戏机等电子设备，本申请实施例对电子设备的种类不作具体限制。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的， 本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
