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、完整地描述，显然，所描述的实施例仅仅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。
作为在本申请实施例中使用的“通信终端”(或简称为“终端”)、“电子设备”包括，但不限于被设置成经由有线线路连接(如经由公共交换电话网络(PSTN)、数字用户线路(DSL)、数字电缆、直接电缆连接，以及/或另一数据连接/网络)和/或经由(例如，针对蜂窝网络、无线局域网(WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器，以及/或另一通信终端的)无线接口接收/发送通信信号的装置。被设置成通过无线接口通信的通信终端可以被称为“无线通信终端”、“无线终端”以及/或“移动终端”。移动终端、电子设备的示例包括，但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(PCS)终端；可以包括无线电电话、寻呼机、因特网 /内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。
目前的折叠电子设备，如手机等，通常包括相互枢接的第一壳体与第二壳体，以及覆盖在第一壳体以及第二壳体一侧的柔性显示屏。第一壳体与第二壳体能够翻转至呈叠合状，此时，柔性显示屏呈对折状态。然而，由于柔性显示屏的边缘通常固定地连接于第一壳体及第二壳体，当柔性显示屏对折时，其大致中部的区域会受到来自其边缘以及第一壳体及第二壳体的挤压力和电子设备内部元件，如转轴机构等的支撑力，并因此产生拱起变形。
鉴于此，本申请发明人致力于研究如何改善柔性显示屏的拱起状况，为此，发明人提出一种转轴机构，将转轴机构的大部分结构设置于柔性显示屏的侧边部分而非柔性显示屏的下方，通过将转轴机构基本设置于柔性显示屏沿着转动轴线方向的两端，避免了转轴机构位于柔性显示屏下方但在弯折时对柔性显示屏产生支撑力或挤压力的情况，可以较为有效地缓解柔性显示屏在弯折时的拱起现象。然而，发明人经过验证后，进一步发现，将转轴机构设置于柔性显示屏的侧边部分时，会导致电子设备的边框显著增厚，不利于实现大屏占比。
因此，发明人进一步研究，以期寻求一种避免柔性显示屏在弯折时的拱起现象且边框较窄的电子设备及其转轴机构。发明人的研究包括但不限于包括：研究不同结构的转轴机构对上述拱起现象的改善作用以及对边框的影响、研究不同位置的转轴机构对上述拱起现象的改善作用以及对边框的影响等等。经过大量、反复的试验后，发明人提出本申请的转轴机构以及应用该转轴机构的可折叠电子设备。该转轴机构包括彼此可转动连接的基座和转动组件，转动组件包括支架、联动件以及导引件。支架与基座间隔设置，联动件设置于基座和支架之间。联动件包括本体和设置于本体的驱动部；本体的一端可转动地连接于基座，另一端可滑动地连接于支架。导引件可转动地连接于支架；导引件设有滑槽，驱动部至少部分地容置于滑槽中；基座和转动组件相对转动时，驱动部在滑槽中滑动以驱使导引件相对支架转动。该可折叠电子设备包括第一壳体、第二壳体以及可折叠屏上述的转轴机构。第一壳体连接于支架，第二壳体连接于基座。第一壳体以及第二壳体通过基座及转动组件相对转动呈折叠装或展开状。可折叠屏连接于第一壳体以及第二壳体，且叠置于导引件上。
本申请实施例提供的电子设备及其转轴机构中，可折叠屏设于壳体组件以及转轴机构上时，第一壳体以及第二壳体能够借由基座和转动组件之间的相对转动而转动，此时驱动部在滑槽中滑动以驱使导引件相对支架转动，导引件转动时发生偏转而形成一定的避让空间，该避让空间使转轴机构避免对可折叠屏的背面形成抵压力或者支撑力，并且提供空间以便于容纳可折叠屏在折叠时产 生的弯折结构，因此能够避免可折叠屏产生背离于转轴机构的拱起变形的趋势，也即，可折叠屏在无外力支撑拱起的情况下，在自然弯折状态中，能够朝向转轴机构凹下变形，从而避免可折叠屏产生不符合其弯折趋势的变形。因此，上述的转轴机构能够在可折叠屏折叠时对可折叠屏进行保护，避免可折叠屏因折叠的不规则变形而产生的损坏，延长了可折叠屏的使用寿命。

转动组件30包括支架32、联动件34以及导引件36，支架32与基座10间隔设置，联动件34可活动地设置于支架32与基座10之间，导引件36可转动地连接于支架32，并与联动件34滑动配合。当基座10和转动组件30相对转动时，联动件34基于滑动配合结构带动导引件36转动，使导引件36在转轴机构100折叠时能够转动呈现出一定的倾斜角度，以为可折叠屏200的弯折提供一定的容纳空间，从而避免转轴机构100抵推可折叠屏200使可折叠屏200产生拱起现象。在本实施例中，支架32连接于第一壳体303，如，支架32可以通过螺钉等紧固件固定于第一壳体303内，且支架32位于可折叠屏200与第一壳体303之间。请参阅图7，支架32设置有导引槽321，导引槽321用于容纳联动件34的部分结构，使联动件34能够与支架32滑动连接。在本实施例中，导引槽321大致为直槽结构，其贯穿支架32朝向基座10的一侧而形成开口323，开口323用于允许联动件34穿设。导引槽321的延伸方向大致垂直于转动轴线O。
联动件34包括本体341和设置于本体341的驱动部343，本体341的一端可转动地连接于基座10，另一端可滑动地连接于支架32。进一步地，在本实施例中，本体341包括转动部3411以及滑动部3413，转动部3411以及滑动部3413分别位于本体341的相对两端。
转动部3411可转动地连接于基座10，例如，转动部3411通过第一枢轴3412可转动地连接至基座10的座体12。第一枢轴3412的结构不受限制，其可以是直接成型于转动部3411上的大致轴状结构，也可以是独立于转动部3411的转轴、销轴等结构。
滑动部3413大致呈平板状，其可滑动地容置于支架32的导引槽321内，当基座10带动联动件30转动时，滑动部3413可在导引槽321内滑动，避免转动过程中的结构干涉，以使转轴结构100的转动较为顺畅。进一步地，在本实施例中，滑动部3413为两个，两个滑动部3413相对间隔设置，两个滑动部3143共同用于固定驱动部343。在其他的一些实施例中，滑动部3413和导引槽321之间的结构可以采用其他形式的导向结构替代，例如，支架32可以设有导向槽、导向孔等结构，滑动部3413可滑动地与该导向槽、导向孔相配合；或者，滑动部3413与支架32之间可以通过导轨与导槽的形式实现滑动配合。
进一步地，本体341还可以包括避位部3415，避位部3415连接于转动部3411和滑动部3413之间。在本实施例中，避位部3415相对于滑动部3413弯折，以与滑动部3413共同形成用于容置导引件36的容纳空间3416。当联动件34带动导引件36相对支架32转动时，导引件36相对联动件34发生倾斜，容纳空间3416为倾斜的导引件36提供足够的活动空间，以避免结构干涉导引件36的运动，并使转轴机构100的整体结构较为紧凑。
驱动部343连接于滑动部3413，驱动部343用于带动导引件36运动。进一步地，在本实施例中，驱动部343大致呈柱状，其连接于两个滑动部3413之间，以利用两个滑动部3413之间形成的空间容纳与导引件36滑动配合并避免干涉导引件36的运动，使配合结构较为紧凑。
请参阅图8至图9，导引件36设置于支架32朝向可折叠屏200的一侧。导引件36设置有滑槽361，滑槽361用于与驱动部343滑动配合。进一步地，驱动部343至少部分地容置于滑槽361中，当基座10和转动组件30相对转动时，驱动部343在滑槽361中滑动，以驱使导引件36相对之间32转动并发生倾斜。
进一步地，导引件36包括连接部363以及导引部365。
在本实施例中，连接部363大致呈板状，其设置于支架32朝向可折叠屏200的一侧，并可转动地连接于支架32。连接部363同时还可以用于支撑可折叠屏200以避免可折叠屏200在展开状态下发生塌陷。进一步地，通过导引件36、联动件34、支架32与基座10之间的转动、滑动连接关系，可以使转轴机构100直接设置于可折叠屏200的非显示侧(也即背面)并能够支撑可折叠屏200，避免转轴机构100设置在可折叠屏200的四周边缘而占据电子设备500的边框空间，有利于实现更大的屏占比。
在一些实施例中，连接部363背离支架32的一侧还可以与可折叠屏200固 定连接(如，粘贴等)，以在连接部363转动倾斜时，能够带动可折叠屏200朝向转轴机构100的方向弯折，对可折叠屏200的弯折状态形成一个导引作用，使可折叠屏200在折叠状态下朝向预定的方向弯折变形，以避免可折叠屏200在折叠时产生异常拱起或弯曲形变。
导引部365设置于连接部363与支架32之间，滑槽361开设于导引部365，以允许导引部365能够与联动件34的驱动部343滑动配合。进一步地，导引部365连接于连接部363朝向支架32的一侧，并相对于连接部363的表面凸出，使导引部365至少部分地容置于两个滑动部3413之间的空间，驱动部343则穿设于滑槽361，以使导引件36和联动件34之间的配合结构更为紧凑。
请参阅图10，在本实施例中，导引部365上的滑槽361大致为相对连接部363倾斜设置的槽。滑槽361具有相对的第一端3611和第二端3613，第一端3611邻近基座10，第二端3613远离基座10。第一端3611和第二端3613共同定义了滑槽361的延伸方向，也即，滑槽361的延伸方向可以理解为自第一端3611指向第二端3613的方向，或者可以理解为自第二端3613指向第一端的3611的方向。滑槽361的延伸方向与导引槽321的延伸方向大致一致，均由支架32朝向基座10延伸。进一步地，滑槽361的延伸方向大致相对连接部363倾斜设置，使驱动部343在滑槽361中滑动时，能够在第一端3611和第二端3613之间滑动以驱使连接部363转动并倾斜。
进一步地，如图10所示，根据滑槽361的倾斜结构，第一端3611与连接部363之间的距离小于第二端3613与连接部363之间的距离，使转轴机构100在折叠时，联动件34相对基座10转动并朝向远离支架32的方向运动，驱动部343则由第二端3613滑动至第一端3611，从而驱使导引件36相对支架32转动并倾斜。
请参阅图11，在本实施例中，转动组件30还可以包括连接件38，连接件38的一端可转动地连接于基座10，另一端可转动地连接于支架32，以保持基座10和支架32之间的相对位置大致不改变，有利于提高转轴机构100转动的稳定性。在本实施例中，连接件38与联动件34大致并列设置，连接件38通过第二枢轴3811与基座10转动连接，第二枢轴3811与第一枢轴3412大致同轴设置，由此，连接件38和联动件34大致同轴地连接于基座10，能够保证连接件38和联动件34之间的转动互不干涉，使转轴机构100的多个部件在转动过程中的转动一致性，避免零部件发生错动导致可折叠屏200损坏。应当理解的是，在本申请实施例中，“并列设置”应当理解为二者大致间隔设置，俗称“并排”，并不要求二者被限制在同一个平面上间隔设置。例如，连接件38的侧边与联动件34的侧边相对间隔，转动组件30在转动时，连接件38与联动件34二者的其中之任一个可以转动，二者之间的相对距离可以保持不变。
进一步地，在本实施例中，连接件38与联动件34大致并列设置，导引件36设置于连接件38与联动件34的同一侧，连接件38朝向导引件36的一侧设有避位空间3813，避位空间3813用于部分地容纳导引件36。当联动件34带动导引件36相对支架32转动时，导引件36相对连接件38发生倾斜，避位空间3813为倾斜的导引件36提供足够的活动空间，以避免结构干涉导引件36的运动，并使转轴机构100的整体结构较为紧凑。
进一步地，在本实施例中，连接件38可以包括第一转轴部381、第二转轴部383以及过渡部385，过渡部385连接于第一转轴部381和第二转轴部383之间。第一转轴部381可转动地连接于基座10，第二转轴部383可转动地连接于支架32，过渡部385具有弯折结构以形成上述的避位空间3813。应当理解的是，“第一转轴部”、“第二转轴部”的命名不应对连接件38的具体结构形成限制,第一转轴部381、第二转轴部383应理解为连接件38上具有转动连接的部位，也可统称为“转轴部”，说明书中为便于描述连接件38与基座10和支架32之间的连接关系，以“第一转轴部”、“第二转轴部”的命名区分转动连接的部位。
进一步地，第一转轴部381可以作为上述的第二枢轴3811，用以实现连接件38和基座10之间的转动连接。第一转轴部381具有弧面结构，并可滑动地容置于基座10的转轴槽16中，当第一转轴部381在转轴槽16中滑动时，连接件38基于转动轴线O转动。具体而言，在图示的实施例中，第一转轴部381可以大致呈部分圆柱状，其也可认为是可转动地容置于转轴槽16中，第一转轴部381的相背离的两个表面分别与凹陷部121、配合面141相对设置，例如，第一转轴部381的表面大致叠置于凹陷部121和配合面141，以避免第一转轴部381在转轴槽16中转动时发生松动的情况，从而保证转轴机构100的转动较为平稳。
进一步地，连接件38还可以包括定位部387，定位部387设置于第一转轴部381上，其用于与基座10的结构配合，实现转动组件30和基座10之间相对角度的定位。相应地，基座10还可以包括配合部18，配合部18可以设置于转轴槽16内，以用于和定位部387相嵌配合，从而固定转动组件30和基座10之间的角度。具体而言，定位部387可以为凸出于第一转轴部381的表面的凸起结构，配合部18可以为设置于凹陷部121的凹陷结构或设置于配合面141的凹陷结构，当第一转轴部381在转轴槽16中滑动时，定位部387可选择地与配合部18相嵌配合，当没有外力的情况下，定位部387可稳定地容置于配合部18中，以使转动组件30和基座10之间的角度得以固定。进一步地，定位部387或/及配合部18的数量可以为多个，多个定位部387或/及配合部18可以沿着第一转轴部3813的转动方向间隔设置，也即，沿绕着转动轴线O的方向间隔设置，从而实现转动组件30和基座10之间的多个角度的定位。在其他的一些实施例中，定位部387及配合部18之间的凹槽、凸起结构可以互换，例如，定位部387 为凹槽，配合部18为凸起等，只要二者共同配合实现转动组件30和基座10之间的角度定位即可，本说明书不再一一赘述。
请参阅图12，图12为转轴机构100的结构示意图，其用模块的画法示出了转轴机构100及壳体组件300的大致结构，并不作为对本申请实施例的电子设备500的结构限制。在本实施例中，转轴机构100还包括转轴外壳50，转轴外壳50用于容纳基座10，以为转轴机构100提供整体的防护，并形成模块化的组装方案，有利于运输以及装配。具体而言，转轴外壳50设有收容腔52，基座10设置于收容腔52中，并可以通过螺钉等紧固件固定于转轴外壳。进一步地，转轴外壳50还可以为作为电子设备500的外壳组件，与第一壳体303、第二壳体305共同构成电子设备500的外观面，此时，第一壳体303、第二壳体350分别设置于转轴外壳50的相对两侧。
在本实施例中，一个转轴机构100可以包括两个转动组件30，两个转动组件30包括第一转动组件3001和第二转动组件3003，第一转动组件3001和第二转动组件3003分别设置于基座10的相对两侧，并大致相对基座10呈对称设置。第一转动组件3001连接于第一壳体303，第二转动组件3003连接于第二壳体305。相应地，基座10的转轴槽16也可以为两个，其中一个转轴槽16用于容纳第一转动组件3001的转轴结构，另一个转轴槽16用于容纳第二转动组件3003的转轴结构。第一转动组件3001和第二转动组件3003能够在外力的作用下相对基座10转动，以彼此靠拢呈折叠状态，或彼此远离呈展开状态，以使第一壳体303与第二壳体305能够较为顺畅地相对折叠或展开，且在折叠时的体积相对较小。电子设备500可以包括多个转轴机构100，多个转轴机构100沿其转动轴线O的方向依次排列设置，并连接于第一壳体303和第二壳体305，以使电子色斑500的转动较为平衡且稳定。
在其他的一些实施例中，一个转轴机构100也可以只包括一个转动组件30，而在组装至电子设备100的壳体组件300时，采用两个转轴机构100实现第一壳体303和第二壳体305之间的转动连接。例如，其中一个转轴机构100的转轴组件30连接于第一壳体303、基座10连接于第二壳体305，另一个转轴机构100的转轴组件30连接于第二壳体305。当然，转轴机构100的数量可以为多个，例如，四个，六个，八个等等，以使电子设备500的转动较为平衡且稳定。
请再次参阅图2，电子组件400包括第一电子模组401、第二电子模组403以及柔性电路板405，第一电子模组401设置于第一壳体303内，第二电子模组403设置于第二壳体305内，柔性电路板405电连接于第一电子模组401和第二电子模组403。进一步地，第一电子模组401可以是主板和设置主板的中央处理器、存储器、天线、摄像头和送受话器等。第二电子模组403也可以由印刷电路板和设置于印刷电路板的功能模块构成，第二电子模组403不同于第一电子 模组401，第二电子模组403可以是电池、连接器、指纹模组等。
可折叠屏200依次铺设于第一壳体303、转轴机构100和第二壳体305上。在本实施方式中，可折叠屏200包括柔性显示屏201。柔性显示屏201随第一壳体303与第二壳体305相互翻转呈弯折状或展开状。柔性显示屏201电连接于电子组件400，以使电子组件400能够控制柔性显示屏201运行。
本申请实施例提供的电子设备及其转轴机构中，可折叠屏设于壳体组件以及转轴机构上时，第一壳体以及第二壳体能够借由基座和转动组件之间的相对转动而转动，此时驱动部在滑槽中滑动以驱使导引件相对支架转动，导引件转动时发生偏转而形成一定的避让空间，该避让空间使转轴机构避免对可折叠屏的背面形成抵压力或者支撑力，并且提供空间以便于容纳可折叠屏在折叠时产生的弯折结构(如图13所示)，因此能够避免可折叠屏产生背离于转轴机构的拱起变形的趋势，也即，可折叠屏在无外力支撑拱起的情况下，在自然弯折状态中，能够朝向转轴机构凹下变形，从而避免可折叠屏产生不符合其弯折趋势的变形。因此，上述的转轴机构能够在可折叠屏折叠时对可折叠屏进行保护，避免可折叠屏因折叠的不规则变形而产生的损坏，延长了可折叠屏的使用寿命。
进一步地，连接部还可以用于支撑可折叠屏以避免可折叠屏在展开状态下发生塌陷。通过导引件、联动件、支架与基座之间的转动、滑动连接关系，可以使转轴机构直接设置于可折叠屏的非显示侧(也即背面)并能够支撑可折叠屏，避免转轴机构设置在可折叠屏的四周边缘而占据电子设备的边框空间，有利于实现更大的屏占比。
在本申请的实施例中，电子设备500可以是实现小屏显示、或大屏显示、或弯折屏显示的多用途手机，呈现多种使用功能。例如：电子设备500在柔性显示屏201呈折叠状态时，第一壳体303可与第二壳体305叠合在一起，电子设备500可以充当手机使用，方便用户携带，占用空间小。电子设备500在柔性显示屏201呈一定角度弯折时，第一壳体303相对第二壳体305展开，并互成一定夹角，电子设备500可以充当作笔记本电脑使用。而当电子设备500在柔性显示屏201呈展开状态时，第一壳体303相对第二壳体305展开，并相互平齐，电子设备500可以充当平板电脑使用，以增加显示面积，获取更多显示内容，提高用户体验。当然，电子设备500也可以是多用途的平板电脑，或多用途的笔记本电脑，或其他具有多种模式切换的多功能电子设备。
请参阅图14，本实施方式中，柔性显示屏201包括贴于第一壳体303的第一显示部202、贴于第二壳体305的第二显示部203和连接于第一显示部202和第二显示部203之间的弯折显示部204。第一显示部202和第二显示部203分别随第一壳体303和第二壳体305相对地折叠或展开。弯折显示部203随第一显示部202相对第二显示部203折叠或展开而弯折或展开。在一些实施方式中， 第一显示部202、第二显示部203以及弯折显示部204可以为一体结构，使柔性显示屏201为整片式的柔性显示屏；或者，在其他的一些实施方式中，弯折显示部204为可弯折的柔性部分，而第一显示部202、第二显示部203可以为非柔性部分，第一显示部202、第二显示部203通过弯折显示部204相对地折叠或展开。
进一步地，可折叠屏200还可以包括覆盖柔性显示屏201的柔性透光盖板(图中未示出)。柔性透光盖板贴合于柔性显示屏201上。柔性透光盖板的周缘固定地连接于第一壳体303以及第二壳体305。柔性透光盖板41用于对柔性显示屏201进行防护，并提高电子设备500的外观性能。
