本申请实施例提供的转轴机构可以应用于电子设备，其中电子设备可以是手机、平板电脑、平板电脑配件、可穿戴设备、车载设备、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、个人数字助理(personal digital assistant，PDA)等移动终端，或者，也可以是数码相机、单反相机/微单相机、运动摄像机、云台相机、无人机等专业的拍摄设备，本申请实施例对电子设备的具体类型不作限制，为了方便理解，以下以电子设备为手机为例进行说明。
请参考图1至图3，图1为本申请一种实施例所提供转轴机构应用于电子设备中的示 意图；图2为图1所示电子设备的分解示意图；图3为图2中转轴机构和主体部组装后的局部示意图；图2中标识出了中心轴线X，图3中标识出了横向中线Y。
本申请实施例提供的电子设备包括柔性屏300、主体部200以及转轴机构100，主体部200的数量为两个，两个主体部200通过转轴机构100连接，利用转轴机构100使得两个主体部200能够相对折叠及展开。对于手机而言，主体部200可以为中框。主体部200根据折叠屏终端而定，本文不做具体先动。后文以主体部200为中框继续介绍技术方案和技术效果。
柔性屏300的至少部分能够支撑在中框之上并且与中框连接，在两个中框相对折叠及展开过程中，柔性屏300同时被处于折叠状态及展开状态。其中，左右两个中框的结构可以相同，也可以不完全相同，两个中框的具体结构可以根据具体产品稳定，本文不做具体限定。
柔性屏300可以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，显示模组可以包括触控屏、发光层、背板层和基板层等结构层。显示模组的具体结构可以根据产品不同而选定。显示模组可以采用液晶显示屏(liquid crystal display，LCD)，有机发光二极管(organic light-emitting diode，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-matrix organic light emitting diode的，AMOLED)，柔性发光二极管(flex light-emitting diode，FLED)，量子点发光二极管(quantum dot light emitting diodes，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。
请参考图3，本申请实施例中转轴机构100包括基座(图中未标识出)和同步机构。其中图3中A处为同步机构的安装位置。基座主要为组成转轴机构的其他零部件提供安装基础，基座可以为一体式结构，当然也可以为分体式结构，即基座可以拆分为多个零件，多个零件通过固定件(例如螺钉)、点胶或者焊接等方式固定连接。通常转轴机构还包括轴盖，轴盖位于基座远离柔性屏的一侧，可以起到遮挡转轴机构100其他零部件作用，提高电子设备外观的美观性。
本申请实施例中的转轴机构100的同步机构用于在折叠或展开过程中使两侧的主体部200相对基座同步转动运动，当然理论上在同步机构的作用下，两侧的主体部200相对基座的转动夹角保持一致，但是可以理解的是，由于装配或者加工偏差的原因，两侧的主体部200在旋转过程中相对基座的两转动夹角可以允许存在一定的角度偏差，即在该角度偏差范围内部，仍然可以视为两主体部同步转动。
请参考图4和图5，图4为本申请实施例第一种示例中同步机构的三维示意图；图5为图4中同步机构的正视图。
本申请实施例中同步机构包括底座7、滑块3、第一摆臂1、第一转动轴5、第二转动轴6、第一摆臂1和第二摆臂2，其中底座7可以与上述基座一体结构，也就是说底座7为基座的一部分，当然底座7和基座也可以为独立的两部件，通过固定件或者其他固定方式(例如焊接、螺钉连接等)固定连接。从图2和图3中可以看出，转轴机构100布置有两组同步机构，分别靠近沿转轴机构轴向的两端部，当然同步机构的数量可以根据电子设备不同而合理选择，不局限于本文中所描述，即转轴机构也可以包括两组或者两组以上的同 步机构。请参考图3，本申请实施例的转轴机构100设置有两组同步机构，两组同步机构关于横向中线Y对称设置，本申请实施例的转轴机构100除了包括同步机构之外，还包括两组端部主摆臂9和中间主摆臂10，其中两组端部主摆臂9与两组同步机构相邻设置，两组端部主摆臂9也相对横向中线Y对称设置。
同步机构的第一转动轴5和第二转动轴6平行设置于底座7上，第一转动轴5和第二转动轴6的长度方向沿转动机构的轴向。第一转动轴5和第二转动轴6可以固定连接底座7，当然也可以转动连接于底座7。在一种示例中，底座7包括第一安装块71和第二安装块72，分别位于底座7沿轴向的两个端部，第一安装块71和第二安装块72上均设置有安装孔，第一转动轴5和第二转动轴6插入安装于第一安装块71和第二安装块72的安装孔内部。本申请实施例中第一安装块71的四个角部具有套筒结构711,套筒结构711的内孔形成安装孔。在一种示例中，第一转动轴5和第二转动轴6相对底座7轴向的限位可以通过限位件实现，限位件可以为螺帽或者锁紧销等部件。
本申请实施例中的第一摆臂1和第二摆臂2，分别套装于第一转动轴5和第二转动轴6，第一摆臂1可以围绕第一转动轴5相对底座7转动，第二摆臂2可以相对第二转动轴6转动。第一摆臂1和第二摆臂2均相对于基座的中心轴线X左右对称设置，第一转动轴5和第二转动轴6分居于中心轴线X的左右两侧。第一摆臂1和第二摆臂2的结构可以相同，当然也可以不同。
需要说明的是，本文将靠近中心轴线X的方向定义为内，相应地，远离中心轴线的方向定义为外。
第一摆臂1和第二摆臂2分别与两侧的主体部连接，例如第一摆臂1和第二摆臂2可以为与主体部固定的摆臂，以带动两侧的主体部相对折叠或展开，本申请实施例将与主体部固定连接的摆臂定义为主摆臂，当然，第一摆臂1和第二摆臂2也可以为与主体部相对活动连接，例如第一摆臂1和第二摆臂2的非铰接端与主体部不直接固定，在转动过程中可以相对主体部相对滑动，本申请实施例将这一类摆臂定义为副摆臂。如图4所示，第一摆臂1和第二摆臂2均可以设置长圆形通孔1a，主摆臂上固定有轴体(图4中未示出，可参考图17理解)，轴体插入长圆形通孔1a内部，这样主体部和主摆臂在转动过程中，第一摆臂1和第二摆臂2相应地会转动并与轴体沿长圆形通孔长度方向滑动。例如端部主摆臂9可以固定有轴体，能够带动与其相邻的同步机构中的摆臂联动。
通常在各摆臂的带动下两侧主体部可以在0°至90°之间往复转动，当摆臂与水平面夹角为0°时，主体部大致处于水平状态以及柔性屏300可以处于展平态，此时柔性屏300整体大致呈水平状态，当摆臂与水平面夹角为90°时，带动两侧主体部转动至竖直状态，柔性屏300处于折叠状态。
本申请实施例中同步机构的第一摆臂1和第二摆臂2二者与主体部的具体连接方式不限，只要第一摆臂1和第二摆臂2与中框之间联动即可，例如轴体可以固定于副摆臂上，主摆臂上设置长圆形通孔，或者主摆臂和副摆臂通过凸块和凹槽的配合方式实现联动等等。本申请实施例同步机构中的滑块3能够沿转轴机构的轴向移动，即滑块3相对底座7仅能在轴向移动。
请参考图6和图7，图6为图4所示同步机构的分解示意图；图7为图4中滑块的三 维示意图。
本申请实施例中，滑块3的两侧均包括具有内孔31a的第一套筒31，第一转动轴5和第二转动轴6分别穿过滑块3左右两侧的第一套筒31内部，滑块3仅能够沿第一转动轴5和第二转动轴6的轴向移动。
本申请实施例中第一摆臂1和第二摆臂2均设置有凸起部，凸起部可以为两个或者更多个，凸起部上可以设置有穿过孔，以供第一转动轴5或者第二转动轴6穿过，也就是说，第一摆臂1和第二摆臂2通过其上设置的凸起部套设于相应转动轴。
请参考图4，该申请中第一摆臂1和第二摆臂2上的凸起部的数量为四个，沿轴向依次间隔布置，根据凸起部作用的不同，本文将四个凸起部定义为两个第一凸起部11和两个第三凸起部13，其中两个第一凸起部11相邻且靠近下方设置，两个第三凸起部13相邻且靠近上方设置。滑块3位于两个第一凸起部11之间，两个第一凸起部11相对的端面设置抵靠部，滑块3的两端面设置有与相应侧抵靠部配合的螺旋面，通过螺旋面与抵靠部的配合，能够实现左右两侧第一摆臂1和第二摆臂2的同步转动。理论上，滑块3两端面的螺旋面与相应侧的抵靠部始终处于抵靠状态。限于滑块3的行程，螺旋面可以仅为一小段螺旋结构，在垂直于轴向的平面内的投影可以为环形结构，环形结构的圆心角可以在0(不包括端点值)至360度(包括端点值)，图7示出了环形结构的圆心角大约为180度的具体示例，环形结构的圆心角在0至180度范围内环形结构的加工比较容易，当然环形结构的圆心角不局限于本文所示可以为0至360度任意数值。
当然凸起部的数量不局限于本文上述所描述的4个，可以为其他数量。
从上文可以理解，与在滑块3两端面之间的主体上开设螺旋槽相比，本申请实施例中螺旋面成型于滑块3的端面，该螺旋面无倒扣结构，可以利用模具直接成型或者通过常规的数控加工成型，成型工艺比较简单，并且螺旋面与抵靠部配合轴向滑动的方式在手机厚度方向占据空间比较小，满足手机等电子设备轻薄化设计需求。
上文给出了在滑块3端面设置螺旋面的具体示例，本领域内技术人员应当理解，在第一凸起部11的端面设置螺旋面，在滑块3端面设置抵靠部同样能够达到上述技术效果。即第一凸起部11和滑块3二者其中一者的端面设置有螺旋面，另一者端面设置有与螺旋面配合的抵靠部即可。
下文以滑块3上设置螺旋面为例介绍几种具体示例。
请结合参考图4、图7和图8理解，图8为图4中第一摆臂1的三维示意图。在第一种示例中，滑块3两侧的第一套筒31的两端面均具有螺旋面，第一凸起部11的数量为两个，两个第一凸起部11沿轴向间隔布置，并且两者具有同轴的穿过孔，第一转动轴5穿过位于左侧的第一摆臂1上第一凸起部11的穿过孔，第二转动轴6穿过位于右侧第二摆臂2上第一凸起部11的穿过孔。两个第一凸起部11相对的表面设有第一抵靠部111和第二抵靠部111’，分别用于与第一套筒31两端面的螺旋面配合抵靠。如图7和图8所示，滑块3的上端面的第一螺旋面311与第一凸起部11端面设置的第一抵靠部111抵靠配合，滑块3的下端面的第二螺旋面311’与另一第一凸起部11端面设置的第二抵靠部111’抵靠配合。
第一摆臂1和第二摆臂2在第一螺旋面311与第一抵靠部111、以及第二螺旋面311’与第二抵靠部111’的配合下同步转动，稳定性比较高。
理论上，为了使第一螺旋面311与第一抵靠部111、以及第二螺旋面311’与第二抵靠部111’能够始终抵靠，第一抵靠部111和第二抵靠部111’之间的间距与第一螺旋面311和第二螺旋面311’之间的间距大致相等。也就是说，位于同一第一套筒31两端面的螺旋面之间的间距与第一抵靠部和所述第二抵靠部之间的间距大致相等。
鉴于加工误差以及装配公差等因素，同步机构组装后螺旋面和抵靠部可能存在在转动过程中不能抵靠的状态，因此本申请实施例还进行了以下设置。
请参见图11、图14、图15，本申请实施例的同步机构进一步包括弹性部件20，在弹性部件20回复力作用下，螺旋面和抵靠部弹性抵靠，即弹性部件20沿轴向处于压缩状态，这样弹性部件能够使螺旋面和抵靠部在摆臂转动过程中时时处于抵靠状态，提高了两侧摆臂转动的同步性。
弹性部件20可以为弹簧，也可以为其他具有弹性的部件，例如硅胶或者橡胶等部件。如图4所示，弹性部件的数量可以为两个，两个弹性部件20可以分别套装于第一转动轴5和第二转动轴6，当然，弹性部件的数量也可以为一个，或者其他数量。
根据弹性部件安装位置的不同，本申请实施例给出了两种具体示例。
请参考图11、图12和图13，图11为本申请实施例第二种示例中同步机构的三维示意图；图12为图11中第一摆臂的三维示意图；图13图11中滑块的三维示意图。
在第二种示例中，滑块3仅一个端面设置螺旋面，相应地第一摆臂1和第二摆臂2的第一凸起部11的数量也为一个，第一凸起部11的端面设置有抵靠部。为了方便弹性部件的安装，第一摆臂1和第二摆臂2还设置有第二凸起部12，第二凸起部12与第一凸起部11间隔布置，弹性部件20压装于滑块3与第二凸起部12之间，具体地弹性部件可以压装于滑块3的另一端面与第二凸起部12之间。具体地，滑块3与第二凸起部12相对的端面可以为平面结构，当然也可以进一步设置弹性部件安装座等结构。
该实施例中，滑块3仅一端部加工有螺旋面，结构相对比较简单，占据轴向空间比较小。
其中，第二凸起部12也可以设置与第一凸起部11同轴的穿过孔，用于供相应侧转动轴穿过，这样各凸起部同时与转动轴配合安装，能够提高摆臂安装强度。
为了进一步提高转轴机构转动灵活性，本申请实施例还进一步对同步机构进行了以下改进。
请参考图14至图16，图14为本申请实施例第三种示例中同步机构的三维示意图；图15为图14的正视示意图；图16为图14中第一摆臂的三维示意图。
在第三种示例中，同步机构的滑块3包括第一滑块和第二滑块，弹性部件20压装于第一滑块和第二滑块之间，第一滑块和第二滑块二者相对远离的端面均设有螺旋面，该示例中滑块3的结构与第二示例中滑块3的结构相同，不同的是该示例中设置有两个滑块3，弹性部件压装于两滑块3之间，相应地，第一摆臂1和第二摆臂2上均设置有两个间隔布置的第一凸起部11，两第一凸起部11相对表面设置有抵靠部，即该示例中第一摆臂1和第二摆臂2结构与第一示例中第一摆臂1和第二摆臂2结构大致相同，两第一凸起部11之间的间距也可能略有差异。
在弹性部件回复力作用下，弹性部件两侧滑块3的螺旋面能够与相应侧第一凸起部11 的抵靠部始终抵靠。
同样，该示例中弹性部件的数量也为两个，分别套装于两侧的第一转动轴5和第二转动轴6。
以上三种实施例的差异仅是在于滑块3与摆臂(第一摆臂1或第二摆臂2)之间配合位置结构不同，同步机构的其他结构可以大致相同。
请进一步结合参考图6和图10，本申请实施例的同步机构的底座7设置有导向轨712，例如导向轨712设置于第一安装块71，滑块3设置有凹槽32，导向轨和凹槽二者沿轴向延伸，导向轨712和凹槽32轴向滑动配合，这样导向轨和凹槽进一步对滑块3起到轴向运动导向的作用，同时也提高滑块3滑动的稳定性。
当然，底座7上设置凹槽，滑块3上设置于凹槽配合的导向轨也是可以说实现上述技术效果的。
为了提高电子设备折叠及展开时的手感，同步机构还可以进一步设置有阻尼装置4，用于提供第一摆臂1和第二摆臂2转动阻尼。阻尼装置4直接安装于第一摆臂1和第二摆臂2之间，当然阻尼装置4也可以间接与第一摆臂1和第二摆臂2连接。
本申请实施例中，阻尼装置4包括周向与底座7限位且能够沿轴向伸缩的弹性阻尼部件，也就是说，弹性阻尼部件能够沿轴向相对伸缩运动，但是与底座7周向被制约二者不能相对转动。第一摆臂1和第二摆臂2均具有第一凸凹面，弹性阻尼部件具有与第一凸凹面一一相对应且弹性抵靠的第二凸凹面，第一凸凹面1b和第二凸凹面4a均为沿周向圆滑过渡的波浪面，波浪面的凹面和凸面之间的起伏程度可以根据电子设备所需的阻尼大小而合理选定。第一摆臂1和第二摆臂2转动过程中，第一凸凹面相对第二凸凹面相对滑动并且弹性抵靠所产生的摩擦力能够提供转动阻尼，当第一凸凹面和第二凸凹面二者的较高点接触时摩擦力比较大，可以实现悬停功能。
本申请实施例中第一摆臂1和第二摆臂2均设置有两个间隔布置的第三凸起部13，第三凸起部13设置有供相应侧转动轴穿过的穿过孔，第一转动轴5穿过左侧第一摆臂1的第三凸起部13的穿过孔，第二转动轴6位于右侧第二摆臂2的第三凸起部13的穿过孔。结合上述描述，第一转动轴5同时设于同侧各凸起部(第一凸起部11、第二凸起部12和第三凸起部13)的穿过孔内部，以实现与底座7的转动连接。第三凸起部13相对的两表面均设置有第一凸凹面1b，也就是说第三凸起部13也为套筒结构，本文定义为第三套筒，第三套筒的端面设置有第一凸凹面1b，该实施例中第一凸凹面1b与转动轴同轴设置，结构紧凑。
请参考图9，相应地，弹性阻尼部件的四个端部也可以具有套筒结构，本文定义为第二套筒441，第三套筒与第二套筒441相对应端部设置第二凸凹面。该实施例中弹性阻尼部件包括第一支架43、第二支架44和第一弹性件41，第一弹性件41压装于第一支架43和第二支架44之间，第一支架43和第二支架44二者两侧均具有通孔4a的第二套筒441，两侧的第二套筒441分别套设于第一转动轴5和第二转动轴6，也就是说第一支架43(第二支架44)同时套设于第一转动轴5和第二转动轴6，这样第一支架43(第二支架44)不能相对底座7转动，但是能够沿第一转动轴5和第二转动轴6的轴向滑动。
其中，为了简化加工及提高组装效率，第一支架43和第二支架44可以为相同结构。
当两侧的第一摆臂1和第二摆臂2同时转动时，两摆臂上的第一凸凹面1b相对两侧套筒的第二凸凹面4a相对转动，同时为第一摆臂1和第二摆臂2提供转动阻尼，在实现第一摆臂1和第二摆臂2同步转动的同时提升电子设备的使用手感。
本申请实施例中第一弹性件41的数量可以为两个，两个弹性件分别套设于第一转动轴5和第二转动轴6，每一个第二套筒远离第一弹性件41的端部均设置有第二凸凹面。第一转动轴5和第二转动轴6能够分别为两个第一弹性件41的伸缩起到导向作用。
当然，第一弹性件41的个数也可以为一个，或者更多个。
通常第一凸凹面和第二凸凹面之间弹性抵靠力越大，转动阻尼也相应越大。为了提高阻尼装置4的转动阻尼，还可以进一步增加第二弹性件42，第二弹性件42可以设置于两个第一弹性件41之间，同时第一支架43和第二之间相对侧面可以设置用于安装第二弹性件42的支座，如图9所示，第一支架43和第二支架44上设置有导向杆，第二弹性件42套装于导向杆。
第一弹性件41和第二弹性件42可以均为弹簧。
上文第三种示例介绍了将滑块3分为第一滑块和第二滑块，以实现螺旋面与抵靠部弹性抵靠的具体实施方式，当然将第一摆臂1和第二摆臂2分成两部分以实现螺旋面与抵靠部弹性抵靠也是可以的。
阻尼装置可以设置于第一摆臂和第二摆臂之间，当然也可以为单独设置，设置于转轴机构的其他摆臂之间，即与同步机构相对独立，如图17所示。
请参考图17至图19，图17为本申请实施例第四种示例中同步机构的三维示意图；图18为图17中第一分摆臂1-1和第二分摆臂1-2的分解示意图；图19为图17所示同步机构的分解示意图。
在第四种示例中，第一摆臂1和第二摆臂2均包括沿轴向能够相对分离的第一分摆臂1-1和第二分摆臂1-2，第一分摆臂1-1和第二分摆臂1-2为两个独立的部件，沿轴向能够相对移动，移动量可以根据实际电子设备而定。并且第一分摆臂1-1和第二分摆臂1-2沿周向具有约束以使二者同步转动，第一分摆臂1-1和第二分摆臂1-2通过约束件约束二者不能相互转动，约束件可以为凹槽和凸块结构，例如第一分摆臂1-1和第二分摆臂1-2其中一者设置凹槽1c，另一者设置插入凹槽1c的凸块1-21以限制二者周向转动。凹槽1c和凸块1-21可以设置于第一分摆臂1-1和第二分摆臂1-2的非铰接端。当然第一分摆臂1-1和第二分摆臂1-2周向约束方式不局限于上述方式，还可以为其他方式，例如通过卡扣等方式。
第一分摆臂1-1和第二分摆臂1-2均具有凸起部，该示例中将第一分摆臂1-1的凸起部定义为凸起部A1-11，第二分摆臂1-2的凸起部定义为凸起部B1-12，上述定义仅是为了描述技术方案的清楚简洁，其中凸起块A1-11和凸起块B1-12的结构与上述第一种示例至第三种示例中的第一凸起部11可以相同。与第一种示例不同的是，第一种示例上与滑块3配合抵靠的两个第一凸起部11位于同一摆臂上，而该示例中与滑块3配合抵靠的凸起部位于两个分摆臂上。滑块3位于同一侧的凸起部A1-11和凸起部B1-12之间，在弹性部件的作用下，滑块3的沿轴向布置的两端面分别与凸起部A1-11和凸起部B1-12弹性抵靠。
当然凸起部A1-11和凸起部B1-12的端面形状可以为多种形式，只要能够实现与滑块 3的配合抵靠即可。
滑块3位于凸块部A1-11和凸块部B1-12之间，滑块3的端面可以设置螺旋面，凸块部A1-11和凸块部B1-12为能够沿螺旋面滑动的圆滑面，例如弧形面或者小段长度的螺旋面。图中示出了滑块3两端面设置螺旋面，凸块部A1-11和凸块部B1-12相对应的端面设置抵靠部。
该示例中，将第一摆臂1和第二摆臂2设计为分体式结构，二者均分成相对独立的第一分摆臂1-1和第二分摆臂1-2，二者沿轴向能够相对远离或者靠近，当滑块3安装到位后，可以调整第一分摆臂1-1和第二分摆臂1-2的轴向位置以使抵靠部和螺旋面处于抵靠状态，这样不仅方便滑块3的安装，而且将一个摆臂设计为两部分也可以降低摆臂的加工工艺。
上文描述了滑块3两端设置螺旋面、第一分摆臂1-1和第二分摆臂1-2均设置凸起部的示例，本领域内技术人员应当理解，滑块3单侧设置螺旋面，第一分摆臂1-1和第二分摆臂1-2仅一者设置凸起部也是能够实现上述技术效果的。当然，滑块3上设置抵靠部，第一分摆臂1-1和第二分摆臂1-2的凸起部端面设置于抵靠部配合的螺旋面也能实现上述技术效果，关于技术细节本文不做赘述。
该示例中底座7上同样可以设置第一转动轴5和第二转动轴6，第一转动轴5和第二转动轴6平行设置，第一摆臂1围绕第一转动轴5转动，第二摆臂2围绕第二转动轴6转动，滑块3能够沿第一转动轴5和第二转动轴6滑动。这与上述几种示例结构相同。
为了提高转轴机构的稳定性，同一侧的第一分摆臂1-1和第二分摆臂1-2可以均与相应侧转动轴套装，例如第一摆臂1的第一分摆臂1-1的凸起部A1-11和第二分摆臂1-2的凸起部B1-12可以设置有同轴穿过孔，以供第一转动轴5穿过，第二摆臂2的第一分摆臂1-1的凸起部A和第一分摆臂1-2的凸起部B可以设置有同轴穿过孔，以供第二转动轴6穿过。
该示例中滑块3的结构可以与第一种示例相同，滑块3的两侧均设置有第一套筒31，两侧的所述第一套筒31分别滑动套设于第一转动轴5和第二转动轴6，每一个述第一套筒31的两端面均具有螺旋面311，分别与相应侧凸起部A1-11的抵靠部和凸起部B1-12的抵靠部配合。
螺旋面的长度、技术效果与上述示例相同，此处不做详述。
在第四种示例的基础上，弹性部件的安装位置可以有多种形式，下文给出了两种不同的安装方式。
请再次参考图17，在第四种示例的基础上，同步机构可以进一步包括第三摆臂3-1和第四摆臂3-2，分别转动连接于底座7的两侧，第三摆臂3-1和第一摆臂1位于底座7同一侧并且二者沿轴向依次布置，第四摆臂3-2与第二摆臂2位于同侧，并且第四摆臂3-2和第二摆臂2沿轴向依次布置，第一摆臂1和第三摆臂之间压装有弹性部件，第四摆臂与第二摆臂2之间压装有弹性部件。弹性部件可以安装于远离第一摆臂1和第二摆臂2铰接端的非铰接端。
其中第三摆臂3-1和第四摆臂3-2可以能够与主体部固定连接，即作为主摆臂，当然也可以为在转动过程中能够与主体部相对滑移，作为副摆臂，第三摆臂和第四摆臂只要能 够与主体部形成联动机构即可。
如图17所示，为了使底座7同一侧的各摆臂相对底座7同角度摆动，本申请实施例中在各摆臂上开设长圆形通孔1a，如图所示第一分摆臂1-1、第二分摆臂1-2和第三摆臂3-1均设置有长圆形通孔1a，第一轴体3-3同时设于各摆臂的长圆形通孔1a内部，当主体部转动时，第一轴体3-3能够在长圆形通孔1a内部滑动以带动各摆臂同步转动。同理，底座7右侧的各摆臂也设置长圆形通孔1a和位于各长圆形通孔1a内部的第二轴体3-4以协调各摆臂同角度摆动。
当然，各摆臂上开设的孔不局限于长圆形通孔，还可以为其他结构。即左侧的摆臂开设有第一孔，右侧的各摆臂开设第二孔，第一轴体贯穿各第一孔以实现左侧各摆臂同步转动，第二轴体贯穿各第二孔以实现右侧各摆臂同步转动。
在该示例中，弹性部件包括第一弹性部件201和第二弹性部件202，分别套装于第一轴体3-3和第二轴体3-4，该示例中第一轴体3-3和第二轴体3-4能够同时起到对两弹性部件安装及导向的功能，该同步机构结构比较紧凑。
并且第一弹性部件位于第一摆臂1的转动轴外侧，其两端支撑于第一摆臂1和第三摆臂的非转动端，第二弹性部件位于第二摆臂2的转动轴外侧，其两端支撑于第二摆臂2和第四摆臂的非铰接端。将第一弹性部件和第二弹性部件设置于远离各摆臂转动轴的外端部，空间相对比较大，设计灵活性比较高。
第一弹性部件201可以对左侧第一分摆臂1-1施加一个朝向第二分摆臂1-2的弹性力，以推动第一分摆臂1-1朝向第二分摆臂1-2运动，进而使第一分摆臂1-1的抵靠部(上方抵靠部)与滑块3的螺旋面抵靠压紧，同时滑块3朝向第二分摆臂1-2运动，滑块3另一端的螺旋面与第二分摆臂1-2的抵靠部111(下方抵靠部)也抵靠接触。
同理，在第二弹性部件201的弹性回复力作用下，滑块3右侧两端面的螺旋面与其相应的抵靠部也抵靠接触。
该示例中，为了提升电子设备折叠及展开手感，同样可以设置阻尼装置4，阻尼装置4的结构与第一示例中阻尼装置4结构可以相同，阻尼装置4可以安装于两个第一分摆臂1-1、或两个第二分摆臂1-2之间，或者安装于第三摆臂3-1和第四摆臂3-2之间。附图17-图19给出了阻尼装置4安装于第三摆臂3-1和第四摆臂3-2之间的具体结构。阻尼装置4包括周向与底座7限位且能够沿轴向伸缩的弹性阻尼部件，第三摆臂3-1和第四摆臂3-2均具有第一凸凹面，弹性阻尼部件具有与第一凸凹面一一相对应且弹性抵靠的第二凸凹面，当第三摆臂和所述第四摆臂转动时，第一凸凹面相对第二凸凹面相对转动以提供阻尼。
该示例中，第三摆臂3-1和第四摆臂3-2均设置有两个间隔布置的凸起部C3-11，凸起部C3-11设置有供相应侧转动轴穿过的通孔，两凸起部C3-11相对的两表面均设置有第一凸凹面1b。
弹性阻尼部件包括第一支架43、第二支架44和第一弹性件41，第一支架43和第二支架44二者两侧均具有第二套筒，两第二套筒分别套设于第一转动轴5和第二转动轴6，第一弹性件41压装于第一支架43和第二支架44之间，每一第二套筒远离第一弹性件41的端部均设置有第二凸凹面4a。
在另一种示例中，弹性部件与阻尼装置4的弹性件设计为一体式结构，即阻尼装置4中的弹性件既能够起到转动阻尼的功能，也能够起到使抵靠部和螺旋面抵靠的功能，同步结构的具体结构如下。
请参考图20，图20为本申请实施例第五种示例中同步机构的结构示意图。
在第五种示例中，弹性部件包括两个第一弹性件41，分别套装于第一转动轴5和第二转动轴6，第一弹性件41与底座7周向限位，第二弹性件42与底座7周向限位，第一弹性件41和第二弹性件42至少一个端部能够与相应侧的摆臂凸凹面抵靠配合以提供转动阻尼。图20中示出了第一分摆臂1-1设置套筒1-10，套筒1-10设置有弹性部件凸凹配合的凸凹面的示例。也就是说，第一弹性件41不能相对底座7周向转动，第二弹性件42也不能相对底座7周向转动，这样当各摆臂相对底座7转动时，因第一弹性件41至少与一端摆臂凸凹面抵靠，二者之间能够产生摩擦阻尼以满足使用者手感需求。
该示例中，弹性部件包括支架，支架的两侧均具有第二套筒，两第二套筒分别套设于第一转动轴5和第二转动轴6，在弹性部件的作用下，两第二套筒与其相对应的摆臂凸凹面弹性配合以提供转动阻尼。支架的结构可以参考上述各示例中第一支架43和第二支架44的结构。
支架包括位于弹性部件的两端的第一支架43和第二支架44，第一摆臂1和第二摆臂2分别与第一支架43两侧的第二套筒凸凹面弹性抵靠，第三摆臂和第四摆臂分别与第二支架44的两侧第二套筒凸凹面弹性抵靠。
当然，为了提高转轴机构的阻尼力，或者抵靠部和螺旋面之间的接触力，弹性部件还包括第二弹性件42，第二弹性件42位于两个第一弹性件41之间，第一支架43和第二支架44相对侧面还设置有用于安装第二弹性件42的支座。支座可以为轴向延伸的导向杆，第二弹性件42套装于导向杆。
当然，该示例中同步机构也设置有第一轴体3-3和第二轴体3-4，第一轴体3-3贯穿位于底座7左侧的各摆臂的非铰接端，第二轴体3-4贯穿位于底座7右侧的各摆臂的非铰接端。关于第一轴体3-3、第二轴体3-4以及各摆臂安装第一轴体和第二轴体的结构可以参考上文。
本领域内技术人员应当理解弹性部件的设置方式包括但不局限于以下两种方式。例如弹性部件可以不设置于第一轴体3-3和第二轴体3-4上，在第一分摆臂和第二分摆臂相对端面另设弹簧安装座，弹性部件安装于弹簧安装座。
同样，该示例中底座7和滑块3同样可以设置导向轨712和凹槽32，以进一步对滑块3轴向运动进行导向。
该申请中的电子设备包括上述实施例的转轴机构100，故也具有转轴机构100的上述技术效果。
本申请实施例中应用了具体个例对本申请实施例的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请实施例的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请实施例原理的前提下，还可以对本申请实施例进行若干改进和修饰，这些改进和修饰也落入本申请实施例权利要求的保护范围内。
