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，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、传动装置和移动件，所述移动件设有与所述传动装置相啮合的第一传动齿，所述转轴通过所述传动装置与所述移动件相连，所述第一设备主体和所述第二设备主体中的至少一者与所述移动件相连；
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移动件远离所述转轴；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移动件靠近所述转轴。
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移动件远离转轴，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移动件靠近转轴，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
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整的描述，显然，所描述的实施例是本申请一部分实施例，而不是全部 的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。

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13，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、传动装置310和移动件301，移动件301设有与传动装置310相啮合的第一传动齿302，转轴通过传动装置310与移动件301相连，第一设备主体110和第二设备主体120中的至少一者与移动件301相连，即传动装置310可以通过移动件301与第一设备主体110相连，或者，传动装置310通过移动件301与第二设备主体120相连，或者，至少一个传动装置310通过至少一个移动件301与第一设备主体110相连，同时，另外的至少一个传动装置310通过另外的至少一个移动件301与第一设备主体110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，同时，传动装置310可以通过移动件301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。
可选地，移动件301所设置的第一传动齿302可以是条形凹槽，该条形凹槽的数量为至少两个，各条形凹槽可以平行排布，每个条形凹槽可以沿平行于转轴的方向延伸，传动装置310设有与条形凹槽相啮合的结构，从而传递作用力。此外，移动件301可以通过螺钉391等连接结构与第一设备主体110或第二设备主体120固定连接。
传动装置310和移动件301可以仅设置一个，此时转轴通过该传动装置310和移动件301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和移动件301均设置为至少两个，转轴通过至少一个传动装置310和至少一个移动件301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和至少一个移动件301与第二设备主体120传动相连。
可选地，移动件301的数量为至少两个，其中包括第一移动件320和第二移动件330，转轴通过至少一个传动装置310与第一移动件320相连，转轴通过另外的至少一个传动装置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391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391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。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。
此外，转轴可以通过至少两个传动装置310和至少两个第一移动件320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和至少两个第二移动件330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、第一移动件320和第二移动件330的数量为至少两个时，各传动装置310、第一移动件320和第二移动件330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。
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，转轴通过传动装置310驱动移动件301远离转轴，此时第一设备主体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驱动移动件301靠近转轴，此时第一设备主体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与第一移动件320相连，从而与第一设备主体110相连，第二轴220可以通过至少一个传动装置310与第二移动件330相连，从而与第二设备主体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和第一移动件320 驱动第一设备主体110远离转轴，第二轴220通过传动装置310和第二移动件330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和第一移动件320驱动第一设备主体110靠近转轴，第二轴220通过传动装置310和第二移动件330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，进一步地，转动机构还包括支撑板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，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。
可选的实施例中，支撑板340可以为一体式结构，从而简化电子设备的组装工序。当然，支撑板340也可以采用分体式结构，当第一齿轮部341或第二齿轮部342的磨损量超出可接受范围时，仅更换第一齿轮部341或第二齿轮部342即可。
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可以包括丝杠螺母机构等。可选的实施例中，传动装置包括支撑轴311、第一齿轮312、第二齿轮313和同步带314，支撑轴311的第一端与支撑板340相连，第一齿轮312 套设于转轴，第二齿轮313套设于支撑轴311，第一齿轮312通过同步带314与第二齿轮313传动连接，同步带314与移动件301相啮合。当转轴转动时，第一齿轮312随之转动，从而带动同步带314运动，由于同步带314与第一齿轮312、同步带314与第二齿轮313均采用齿啮合的结构，因此同步带314的运动精度较高，以此提升转轴驱动移动件301移动时的传动精度。
可选地，可以通过调整第一齿轮312、第二齿轮313和同步带314的结构参数(例如齿数、直径、长度等)，来调整传动比，从而使得移动件301的移动距离更好地匹配柔性显示屏400的弯折角度，从而更有效地防止柔性显示屏400被过度挤压或被过度拉扯。此外，第二齿轮313可以通过轴承392套设于支撑轴311上，从而使得支撑轴311的运动与第二齿轮313的运动彼此独立，避免两者相互干扰。
同步带314的外表面可以设置用于与第一传动齿302啮合的结构，或者，同步带的内表面设有第二传动齿，移动件301设有朝向该内表面的第一面，第一面设有第一传动齿302，第二传动齿与第一传动齿302相啮合。采用后一实施例时，同步带314的一部分位于移动件301的第一面和第一设备主体110(或第二设备主体120)之间，因此同步带314和移动件301分布得更加紧凑，两者共同占用的空间更小。与此同时，同步带314可以仅内表面设置第二传动齿，该第二传动齿既可以与第一齿轮312、第二齿轮313啮合，又可以与移动件301啮合，因此同步带314的结构更加简单，且其结构强度更高。
进一步的实施例中，转动机构还包括连杆360，连杆360的一端套设于转轴，连杆360的另一端套设于支撑轴311的第二端，换言之，支撑轴311的第二端通过连杆360与转轴相连。该实施例中，连杆360可以向支撑轴311的第二端施加支撑力，从而防止支撑轴311因第二齿轮313的重量、同步带314的重量等因素影响而变形，因此同步带314不容易因支撑轴311变形而与第一设备主体110或第二设备主体120干涉。
同步带314可以位于连杆360背离支撑板340的一侧，即连杆360可以位于同步带314和支撑板340之间，此时，支撑轴311的第二端仍然悬臂设置， 导致支撑轴311仍然存在较高的变形几率。为了防止支撑轴311变形，可以将同步带314设置于支撑板340和连杆360之间，此时连杆360可以更靠近支撑轴311的末端，从而使得支撑轴311几乎不需要悬臂设置，因此支撑轴311出现变形的几率将大大降低。
连杆360可以距离移动件301较远，从而避让移动件301，可选地，移动件301可以整体位于连杆360和支撑板340之间，但这样设置会导致传动装置310过于分散，进而占用过大的空间。因此，为了减小传动装置310占用的空间，可以使同步带314和连杆360均位于移动件301的两端之间，此时，同步带314和连杆360之间的距离较小，传动装置310更加紧凑，从而达到减小传动装置310所占用空间的目的。进一步地，连杆360朝向移动件301的一面设有避让凹部361，该避让凹部361可以避让移动件301，使得移动件301与连杆360之间的距离更近，甚至移动件301的一部分可以位于避让凹部361内，以此进一步减小传动装置310所占用的空间。
当转动机构300还包括支撑板340时，支撑板340与转轴相连，第一设备主体110设有第一导向部101，与第一设备主体110相连的支撑板340远离转轴的一端与第一导向部101滑动配合；和/或，第二设备主体120设有第一导向部101，与第二设备主体120相连的支撑板340远离转轴的一端与第一导向部101滑动配合。第一导向部101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。
进一步可选地，转动机构还包括阻尼器370，阻尼器370设置于转轴。阻尼器370可以提供阻尼作用，从而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。此外，当用户想要使电子设备停留在任意角度而撤去作用力时，阻尼器370可以使第一设备主体110和第二设备主体120保持在目标位置。更进一步地，阻尼器370的数量可以为至少两个，各阻尼器370沿着转轴的轴线 方向间隔排布，从而改善阻尼效果。
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和阻尼器370，并且第一齿轮部341和第二齿轮部342套设于转轴的端部，阻尼器370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，阻尼器370可以位于相邻的转轴支架350之间。
进一步可选地，第一设备主体110设有第二导向部102，转动机构还包括导杆380，导杆380的一端套设于转轴，导杆380的另一端与第二导向部102滑动配合；和/或，第二设备主体120设有第二导向部102，转动机构还包括导杆380，导杆380的一端套设于转轴，导杆380的另一端与第二导向部102滑动配合。可选地，导杆380可以通过轴承392套设于转轴，从而缓解导杆380和转轴之间的磨损。第一导向部101可以为第一设备主体110和第二设备主体120的相对转动提供导向，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。
可选地，阻尼器370可与导杆380配合工作，阻尼器370可以包括弹性件，导杆380套设于转轴的一端与弹性件相连，在电子设备折叠或展开的过程中，导杆380相对于阻尼器370转动，从而向弹性件施加作用力，使得弹性件变形从而储备弹性势能，该弹性势能可以作为阻尼器370的阻尼动力，使得阻尼器370输出阻尼力。该方案不需要额外增加部件为阻尼器370提供阻尼动力，因此可以简化电子设备的结构，并降低其成本。
上述第一导向部101的数量可以设置为至少两个，第一导向部101的数量可与支撑板340的数量相等，各第一导向部101与各支撑板340一一对应配合，从而改善导向效果。第一设备主体110可以设置至少两个第二导向部102，各 第二导向部102可以沿着转轴的延伸方向间隔排布，且各第二导向部102可以与多个导杆380一一对应配合，从而改善导向效果。第二设备主体120可以设置至少两个第二导向部102，各第二导向部102可以沿着转轴的延伸方向间隔排布，且各第二导向部102可以与多个导杆380一一对应配合，从而改善导向效果。
