为了实现第一连接件10和第二连接件20之间的可转动的连接，如图2至图5所示，转轴连接器还包括：轴芯30，第一连接件10和第二连接件 20通过轴芯30可转动地连接。这样，可以实现第一连接件10和第二连接件20之间的枢接。
具体地，如图3所示，轴芯30的第一端与第一连接件10可拆卸地连接，第二连接件20可转动地套设在轴芯30的第二端。
为了实现第二连接件20与轴芯30之间的连接，第二连接件20包括交叉设置的第一安装部22和第二安装部23，第二安装部23可转动地套设在轴芯30上，第二固定部21位于第二安装部23上。这样，即便于第二连接件20与第二屏幕连接，又便于第二连接件20与轴芯30连接。
具体地，第一安装部22和第二安装部23均为筒体，第一安装部22的腔体与第二安装部23的腔体连通。这样，可以便于将第二连接件20套设在轴芯30上。优选地，第一安装部22和第二安装部23垂直设置。
在本实施例中，转轴连接器还包括：阻尼装置40，阻尼装置40设置在第二安装部23的腔体内并与轴芯30的外侧壁抵接。本实施例通过设置阻尼装置40，有利于保证第二连接件20与第二屏幕之间的连接，进而保证第一屏幕与第二屏幕之间的相互转动。
阻尼装置40的具体机构为，如图2至图5所示，阻尼装置40包括：滑柱41，沿第二固定部21的轴向可滑动设置在第二安装部23的腔体中；弹性部件42，弹性部件42的第一端与第二屏幕连接，弹性部件42的第二端与滑柱41的第一端连接；其中，滑柱41的第二端与轴芯30的外侧壁抵接。这样，可以使第二连接件20与第二屏幕之间具有一定的弹性空间，进而有利于实现第一屏幕与第二屏幕之间的稳定旋转。
滑柱41(顶针)与第二连接件20配合形成不同的转动阻尼，顶针固定在第二安装部23的腔体内，配合形成不同转动阻尼，弹簧固定在顶针内以配合产生弹力。
顶针固定第二安装部23的腔体内，通过弹簧顶起的力和轴芯30配合 以形成理想角度的转动阻尼；弹簧一端固定在顶针内，另一端与主屏幕装配形成顶力，顶住轴芯30以形成理想角度转动阻尼，从而连接主、辅屏幕并形成理想角度翻转阻尼。
由于第一屏幕与第二屏幕之间需要进行一定的限位，如图4至图6所示，沿轴芯30的外壁的周向间隔设置有多个凹陷结构，滑柱41的第二端具有朝向轴芯30凸出并与凹陷结构匹配的限位部43；在轴芯30沿预设方向转动时，限位部43依次滑动到相应的凹陷结构内以使第一连接件10和第二连接件20之间的夹角在多个预设值之间切换。
本实施例通过使限位部43位于不同的凹陷结构内，使第一屏幕与第二屏幕之间保持不同的夹角，进而使得第一屏幕和第二屏幕的翻转更加稳定。
为了实现弹性部件42的安装，滑柱41的第一端具有沿其轴向延伸的限位孔，弹性部件42的第二端可拆卸地安装在限位孔中。优选地，弹性部件42为弹簧。
为了保证第一连接件10与轴芯30之间的固定效果，第一连接件10上具有多边形安装孔，轴芯30具有与多边形安装孔相匹配的多边形棱柱，多边形棱柱插设在多边形安装孔内以使轴芯30与第一连接件10可拆卸地连接。
在本实施例中，第一固定部11为板体，第一固定部11上设置有多个用于与第一屏幕连接的安装孔。通过将第一固定部11设置为板体，并在板体上设置多个安装孔，可以便于第一固定部与第一屏幕之间的连接。
本实施例还提供了一种移动终端设备，如图7和图8所示，包括：第一屏幕60、第二屏幕50和转轴连接器70，第一屏幕60和第二屏幕50通过转轴连接器70连接，转轴连接器70为上述实施例的转轴连接器。
在本实施例中，第二屏幕50为主屏幕，第一屏幕60为辅屏幕。
本发明实施例涉及到连接主、辅屏幕有阻尼的翻转转轴结构，通过采 用简单，可靠的结构，在不影响终端产品外形的基础上实现理想的翻转角度。
本发明实施例涉及到移动终端，该移动终端包括显示屏、控制电路板、扬声器以及上述的扬声器音腔结构，扬声器通过金属片与主板电连接，扬声器位于音腔结构的密封空间内。移动终端还包括上述的转轴连接器，转轴连接器固定在主板上，且转轴连接器的两端分别与控制电路板和金属片连接。
与现有的方案相比较，改转轴结构占有体积较小，不同角度有不同翻转阻尼(手感)，对外观造型影响小，结构交易实现。
在本实施例中，上述的可变阻尼转轴结构为在双屏智能正面翻转手机上所用部件，第一连接件固定在主屏幕的下方，第二连接件装配固定在辅屏幕的下方，在主、辅屏幕正面转动过程中，顶针和轴芯配合在0度到180度之间转动以到达理想角度，形成不同阻尼(手感)。这种设置方式不会增加整个移动终端的厚度，并且不会对移动终端底部和顶部的天线产生不利的影响。
如图6所示，滑柱41的限位部43从A点到B点转动过程中为主、辅屏幕0度到90度的旋转范围，所需转动的力逐渐减少；限位部43从B点到C点转动过程中为主辅屏幕从90度到120度旋转范围，所需转动的力逐渐加大。
限位部43从C点到D点转动过程中为主、辅屏幕从120度到180度旋转范围，所需转动的力平滑逐渐减少；达到根据用户在不同场景的使用情况给予不同的转动手感，提升用户体验。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明 的保护范围之内。
