本说明书可使用词组“在一种实施例中”、“在另一个实施例中”，其均可指代根据本公开的相同或不同实施例中的一个或多个。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
在一些实施例中，转轴结构可以连接两个功能件，使得两个功能件可以在一定的范围内转动。转轴结构可以包括第一转动件和第二转动件，第一转动件与第二转动件为可转动连接。因此，将第一转动件和第二转动件分别与两个功能件固定连接后，可以使得两个功能件实现在一定的范围内相对转动。
在一些实施例中，转轴结构可以用于连接头戴式电子设备。具体地，可以将转轴结构中的第一转动件和第二转动分别与头戴式电子设备的两个功能件连接。头戴式电子设备的两个功能件可以分别为镜腿和镜框。上述第一转动件和第二转动可以分别与镜腿和镜框固定连接，从而使得头戴式电子设备的镜腿和镜框可以相对转动，实现头戴式电子设备的折叠收纳和展开佩戴。
在一些实施例中，请参考图1，其示出了根据本申请的用于头戴式电子设备的转轴结构的一实施例的分解结构示意图。在本实施例中，用于头戴式电子设备的转轴结构可以包括第一转动件1和第二转动件3，如图1所示。在本实施例中，上述第一转动件1可以设有至少一个弧形滑轨2。上述弧形滑轨2沿转轴结构的可转动方向的截面为弧形。 上述第二转动件3可以设有与各滑轨2匹配的弧形滑槽4，如图1所示。与上述弧形滑轨2类似，该弧形滑槽4沿转轴结构的可转动方向的截面为弧形。上述各滑轨2可以卡入对应的滑槽4内(或称，滑轨2可以设置在对应的滑槽4所形成的凹槽内)，从而使得滑轨2与对应的滑槽4可以滑动连接，如图2、图3或图4所示，滑轨2在沿滑槽4滑动的过程中，滑轨2靠近滑槽4的一端在滑槽4内移动且不脱离。且上述滑轨2所形成的弧形与滑槽4所形成的弧形(或称，滑轨2和滑槽4截面所成弧形)的弧心可以是重合。图2示出了本实施例中用于头戴式电子设备的转轴结构的俯视图，且在图2所示的转轴结构中，滑轨2完全滑入滑槽4中。上述第一转动件1可以包括一个滑轨2，或者第一转动件1可以包括两个或两个以上滑轨2。相应地，上述第二转动件3可以包括一个滑槽4，或者第二转动件3可以包括两个或两个以上滑槽4。作为示例，上述第一转动件1可以包括一个滑轨2，上述第二转动件3可以包括一个滑槽4，且该滑轨2可以卡入对应的滑槽4中，因此滑轨2沿滑槽4滑动时上述第一转动件1与第二转动件3可以转动。若上述第一转动件1包括两个或两个以上的滑轨2，此时各滑轨2可以相互平行，第二转动件3中滑槽4的数目与滑轨2的数目相同，且相邻滑轨2之间的距离和与其对应的相邻的滑槽4之间的距离相当。这里，对于滑轨2和滑槽4的数目没有唯一的限定。
在上述滑轨2所形成的弧形与滑槽4所形成的弧形的弧心重合的情况下，上述滑轨2和滑槽4可以绕该弧心转动，从而保证相互卡合的滑轨2和滑槽4可以相对滑动，如图3和图4所示。其中，滑轨2可以沿图3中箭头所指示的方向完全滑入滑槽4，此种情况下第一转动件1和第二转动件2之间的相对位置可以如图4所示。进一步地，上述滑轨2还可以沿图4中箭头所指示的方向沿滑槽4滑动，此种情况下第一转动件1和第二转动件2之间的相对位置可以如图4所示。对比图3和图4可以发现，滑轨2在从图3所示的状态下沿滑槽4滑动直到图4所示的状态的过程中，第一转动件1和第二转动件2之间的角度逐渐缩小，直到预设的角度，例如90°。例如，在滑轨2完全滑入滑槽4时，第一转动件1和第二转动件3成180°，而后在滑轨2沿滑槽4滑动以使滑轨2和滑槽4的接触面逐渐减小的过程中，第一转动件1和第二转动件2所成的角度也逐渐减小，直到90°。可以理解的是，第一转动件1和第二转动件3所成角度的范围可以由滑轨2和滑轨4所成弧形的弧度来确定，本领域技术人员可以根据实际的需求进行设定。
在一些可选的实施例中，上述第一转动件1和第二转动件3转动所成的角度的取值范围为(a，b)。上述滑轨2所形成弧的弧心角β和滑槽4所形成弧的弧心角γ中的至 少一个大于或等于b与a的差值。作为示例，a＝90°，b＝180°，那么滑轨2和/或滑槽4的弧心角大于或等于90°。该方式可以保证第一转动件1和第二转动件3在相对转动的过程中所成的角度在(a，b)的范围内变化。可以理解的是，本领域的技术人员还可以根据其他的方式确定滑轨2和滑槽4的弧心角，这里没有唯一的限定。
可选地，对于图1所示的第一转动件1和第二转动件3，通常可以采用将转动件1上的滑轨2旋入第二转动件3的滑槽4的方式，使得第一转动件1和第二转动件3可以形成转轴结构。具体地，上述滑轨2可以沿图5所示的箭头所指示的方向旋入对应的滑槽4中，从而可以实现滑轨2和滑槽4的卡接。通常，上述第一转动件1和第二转动件3可以成一旋入角度(如图5中的虚线所示)来使得滑轨2可以旋入滑槽，该旋入角的度数一般小于第一转动件1和第二转动件3在转动时所成的最小角度，如图6所示，如此可以保证第一转动件1和第二转动件3在转动的过程中滑轨2不会从滑槽4中脱轨，进一步提高了转轴结构的稳定性。例如，上述第一转动件1和第二转动件3在转动时所成的最小角度为90°时，上述旋入角的取值范围可以为(45°，60°)。可以理解的是，上述第一转动件1和第二转动件3还可以采用其他方式装配，这里没有唯一的限定。
可以理解的是，上述滑轨2所形成的弧形与滑槽4所形成的弧形的弧心重合为滑轨2和滑槽4的理论相对位置，但是本领域技术人员可以理解的是，在转轴结构的实际结构中通常会存在一定的误差，这里不对该误差的范围做具体地限定。并且，上述转轴结构通常可以用于头戴式电子设备中，但是本领域技术人员可以理解的是，上述转轴结构还可以应用在其他设备中，这里没有唯一的限定。
本申请的上述实施例中的转轴结构，上述弧形滑轨2卡入弧心重合的弧形滑槽4，从而使得滑轨2可以沿滑槽4滑动，转轴结构可以实现第一转动件1和第二转动3的相对滑动，该实施例通过滑轨和对应的滑槽即可以实现转轴结构，整体结构简单，易于制备，无需繁琐复杂的结构便可有效实现头戴式电子设备中不同器件间的转动连接，简化了头戴式电子设备的制备工艺。
在一些可选的实施例中，如图1所示，上述第一转动件1可以包括相对设置的两个滑轨2，且该两个滑轨2可以相互平行设置。相应地，上述第二转动件3可以包括两个滑槽4，且该两个滑槽4可以与第一转动件1上的两个滑轨2位置对应，从而使得上述两个滑轨2可以卡入对应的滑槽4中。因此，在上述滑轨2沿所卡入的滑槽4滑动时，如图3或图4所示，上述第一转动件1和第二转动件3能够相对转动，即实现两个转动件的转动连接。该方案中，第一转动件1包括相对设置的两个滑轨2和第二转动件3 包括相对设置两个滑槽4，可以使得两个滑轨2卡入对应的滑槽4的情况下，第一转动件1和第二转动件3所构成的转轴结构在相对转动时更加稳定。
在一些可选的实施例中，第一转动件1可以包括两个相对设置的第一侧板5，且两个第一侧板5平行，如图1、图5或图6所示。每个第一侧板5可以包括与另一第一侧板5相背的外表面，也即两块第一侧板5相对的一面为各自的内表面，相背离的一面为各自的外表面。每个第一侧板5的外表面包括与滑轨2的可滑动轨迹匹配的第一弧边。即，可以按照上述滑轨2的运动轨迹弧度、长度等参数确定第一弧边的弧度、长度等参数。
相应地，上述第二转动件3可以包括两个相对设置的第二侧板6，且两个第二侧板6平行，第一侧板5与第二侧板6也平行，如图1、图5或图6所示。其中，第二侧板6可以包括与另一第二侧板6相邻的内表面。也即，两个第二侧板6相对的一面为内表面。上述第二侧板6的内表面可以包括与滑槽4的可滑动轨迹匹配的第二弧边。即，可以按照滑槽4的运动轨迹的弧度、长度等参数确定第二弧边的弧度、长度等参数。可以理解的是，上述滑轨2可以为沿第一弧边设置的滑轨，上述滑槽4可以为第二弧边设置的滑槽，且滑轨和滑槽均是按照滑动轨迹设置的，从而可以保证滑轨2可以卡入滑槽4中，且滑轨和滑槽可以相对滑动。进一步地，结合图3和图5可以看出，将上述滑轨2卡入滑槽4后，上述相对设置的两个第一侧板5至少部分位于相对设置的两个第二侧板6之间。该方案中，针对任一第一侧板5和与该第一侧板5相邻的第二侧板6，滑轨2和滑槽4位于该第一侧板5的外表面和第二侧板6的内表面之间，从而可以进一步保证滑轨2可以沿滑槽4滑动，进一步降低滑轨2从滑槽4中脱轨的风险，进一步提高了转轴结构的稳定性。可以理解的是，上述两个第一侧板5和两个第二侧板6可以通过各种方式进行固定，例如，上述两个第一侧板5可以通过连接杆固定连接，相应地，第二侧板6也可以通过连接杆固定连接。当然，本申请还可以通过设置滑轨和配合滑轨的滑槽的形状的方式等来降低滑轨脱轨的风险。
可以理解的是，上述第一弧边可以是第一侧板5外表面的边(如图1所示)，或者该第一弧边还可以是在第一侧板5的外表面所另外设置的边(未示出)。相应地，上述第二弧边可以是第二侧板6内表面的边(如图1所示)，或者该第二弧边还可以是在第二侧板5的内表面所另外设置的边(未示出)。上述第一弧边和第二弧边的位置如图1所示的情况下，可以使得转轴结构更加紧凑，使得转轴结构可以实现小型化。
在一些可选的实施例中，用于头戴式电子设备的转轴结构还可以包括具有阻尼特性 的阻尼装置。该阻尼装置可以使得转轴结构的第一转动件和第二转动件相对滑动时，两者之间产生阻尼力。
进一步地，如图6所示，用于头戴式电子设备的转轴结构还可以包括阻尼件7。该阻尼件7可以设置在相邻的第一侧板5的外表面和/或第二侧板6的内表面上，也就是设置在第一侧板5和第二侧板6相对并能够相互靠近的一面上。可以理解的是，该阻尼件7可以在相邻的第一侧板5和第二侧板6上均配合设置，也可仅在其中一个侧板上设置，而且阻尼件7的设置数量不定，可以为多个，也可以为一个。该阻尼件7的设置可以调节第一转动件1和第二转动件3转动时产生的阻尼力，使阻尼力增加，从而使得第一转动件1与第二转动件3在转动时可以产生阻尼感。且第一转动件1与第二转动件3还可以基于该阻尼力实现转动定位，即，两个转动件转动至某角度停止时，两个转动件可以均保持当前角度位置不变。具体应用时，阻尼件7的设置种类不限，例如，可以是干涉值为0.2mm、便于安装、限位的耐磨脚垫。上述阻尼件7可以嵌入第一侧板5和/或第二侧板6上预先设置的凹槽内，如图6所示。或者，上述阻尼件7也可采用粘贴等方法固定，具体不限。
在一些可选的实施例中，上述转动结构不仅包括侧板，还可以包括底板。具体地，上述第一转动件1可以包括呈弧形的第一底板10，如图1所示。第一底板10可以连接在两个相互平行的第一侧板5之间形成第一子过线通道。其中，任一第一侧板5向另一第一侧板5的投影落入另一第一侧板5的内表面，也即，任一第一侧板5向另一第一侧板5在垂直该另一第一侧板5方向上的投影落入该另一第一侧板5的内表面处。在本实施例中，该投影几乎与该另一第一侧板5的内表面重合，当然也可以仅部分重合，具体不定。上述第一底板10可以包括至少一个弧形表面，该弧形表面的弧边平行于第一侧板5的外表面，也就是第一底板10可以垂直于任一第一侧板5，或者还可以理解为上述第一底板10的表面可以垂直于第一侧板5的表面。因此，两个第一侧板5和该第一底板10可以配合围成一用于过线的第一子过线通道，如图1所示。
相应地，上述第二转动件3还可以包括呈弧形的第二底板11，如图1所示。上述第二底板11可以连接在两个相互平行的第二侧板6之间形成第二子过线通道。其中，任一第二侧板6向另一第二侧板6的投影落入另一第二侧板6的内表面，也即，任一第二侧板6向另一第二侧板6在垂直该另一第二侧板6方向上的投影落入该另一第二侧板6的内表面处。在本实施例中，该投影与该另一第二侧板6的内表面重合，当然也可以仅部分重合，具体不定。上述第二底板11可以包括至少一个弧形表面，该弧形表面的弧 边平行于第二侧板6的外表面，也就是第二底边11可以垂直于第二侧板5的表面。两个第二侧板6和该第二底板11配合围成一用于过线的第二子过线通道，如图1所示。可以理解的是，上述第一底板10的弧形表面和第二底板11的弧形表面相互平行。因此，当第一转动件1与第二转动件3通过滑轨2与滑槽4结合在一起时，第一转动件1的一端随着滑轨2与滑槽4的结合而同时旋入第二转动件3中，使得第一底板10和第二底板11对应部分重叠，且第一子过线通道和第二子过线通道相互连通，并至少部分交叉在一起，如图6所示，以组合形成完整的为穿戴式电子设备中的数据线提供过线空间的过线通道。本实施例中，头戴式电子设备中的电线便可通过该过线通道穿过，电线由于被侧板和底板遮挡，故不会裸露在外，不仅美观，而且安全。
在一些可选的实施例中，上述滑轨2可以包括两端，其中一端为第一滑轨端21，滑槽4也可以包括两端，其中一端为第一滑槽端41，如图1中的虚线圈所示。其中，第一滑轨端21可以通过第一滑槽端41滑入对应的滑槽4内。当转轴结构趋向于展开状态时，即，第一转动件1和第二转动件3转动成的角度最大(例如，180°)时，第一滑轨端21与第一滑槽端41分别为滑轨2和滑槽4中相互远离的两个端，如图8所示。而当转轴结构趋向于折叠状态时，即第一转动件1与第二转动件3转动成的角度最小(例如，90°)时，第一滑轨端21与第一滑槽端41分别为滑轨2和滑槽4中距离最近的两个端，如图7所示。转轴结构还可以包括弹性装置，在第一滑槽端41向第一结构件中与第一滑轨端21相对的另外一端滑动的情况下(可以理解，转轴结构从折叠状态趋向于展开状态的情况下)，弹性装置可以向第二转动件3施加弹力，该弹力可以推动第二转动件3使其存在第一滑槽端41具有沿滑轨向第一滑轨端21运动的趋势。
在一些实施例中，转轴结构还包括可弹性形变的弹性件8，该弹性件8可以设置在第一转动件1上，并邻近第一滑轨端21处，当第一滑轨端21向远离第一滑槽端41移动至某位置处，第一滑槽端41可以与弹性件8相抵。可以理解的是，第一滑槽端41可以与弹性件8直接相抵，或者第一滑槽端41可以与弹性件8间接相抵。进一步地，随着第一滑轨端21继续滑动，第一滑槽端41会产生顶推该弹性件8的作用力，使弹性件8产生弹性形变。即，弹性件8产生阻碍第一滑轨端继续沿当前方向继续滑动的弹力，也就是该弹性力是用于辅助第一滑轨端反向移动的回弹力。例如，上述弹性件8可以为弹簧，该弹簧可以固定在第一转动件1上，在转轴转动时，第一滑槽端41逐渐远离第一滑轨端21时上述第一滑槽端41可以与弹簧直接相抵压缩弹簧发生形变。
在一些可选的实施例，本实施例中的第一转动件1可以包括靠近第一滑轨端21设 置的滑道，该滑道可设置在弹性件8靠近滑轨2的一侧；如图7和图8所示，转轴结构还包括滑动件9，该滑动件9可滑动地设置在滑道上，且滑动件9的一端与弹性件8接触，当然也可不接触，仅是位置靠近。该滑道例如可以呈条形，如条形滑孔，滑动件9可以位于条形滑道内并能够沿条形滑道移动。当第一滑槽端41向远离第一滑轨端21的方向移动至与滑动件9相抵时，随着第一滑槽端41的继续移动，其会顶推滑动件9，使滑动件9沿滑道移动，以与弹性件8紧密抵靠，并向弹性件8施加顶推力/作用力。相应地，弹性件8会产生回弹力，并向滑动件9施加上述回弹力，从而使得滑动件9可以反向顶推第一滑槽端41，即反向顶推第二转动件3。由此可见，通过上述顶推力、回弹力等各种力的相互作用，可使得第一转动件1与第二转动件3在转动的过程中产生相互制约对方转动的效果，从而可以辅助控制第一转动件1与第二转动件3所形成的转动角度的范围。
在一些可选的实施例中，弹性件8可以为包括第一子弹性杆和第二子弹性杆的弹性杆。上述两根子弹性杆可以是一体成型，如图7或8所示，弹性杆可以是倒“L”型一体杆。上述两根子弹性杆也可以是独立件，之后连接在一起形成的弹性杆。其中，第一子弹性杆的一端与第二子弹性杆的一端固定连接，第一子弹性杆和第二子弹性杆成δ角。上述第一子弹性杆可以固定在第一转动件1上，第二子弹性杆在受到第一滑槽端41直接或间接的作用力时，δ减小，从而产生可以作用于滑槽4的回弹力。例如，第一子弹性杆与第二子弹性杆之间在未受力时，δ夹角呈90°，第一转动件1上设有卡接部，用于将第一子弹性杆固定在第一转动件1上，第二子弹性杆与上述地滑动件9相邻，当第一滑槽4端通过滑动件9顶推第二子弹性杆时，第二子弹性杆向靠近第一子弹性杆的方向移动，从而使得夹角δ减小，同时第二子弹性杆产生回弹力，该回弹力通过滑动件9反作用于第一滑槽端41，以阻碍第二转动件3沿当前方向继续转动，如图8所示。例如，当头戴式电子设备为智能眼镜时，第一转动件1与第二转动件3可以用于转动连接眼镜的镜框12及镜腿13，通过设置上述弹性件8，可以使得用户在佩戴智能眼镜时，镜腿13能够夹紧用户的头部，防止智能眼镜轻易脱落，而且基于弹性件8的弹性，镜腿13可自适应调整，使智能眼镜能够适配多种不同头围，头型的用户，增加适用范围。
在一些可选的实施例中，转轴结构还可以包括在第一转动件1上沿上述滑道设置的限位板14，该限位板14可以将滑动件9的滑动区域限定在滑道。也即，滑动件9位于限位板14和滑道之间，以确保滑动件9不脱离滑道，同时能够稳定地沿滑道滑动。
在一些可选的实施例中，上述转轴结构还包括两个防脱件19，如图7所示，两个防 脱件19可以分别设置在两个相对设置的第一侧板5的两侧，防脱件19的内表面与第一侧板5的外表面可以相对设置。防脱件19的内表面与第一侧板5的外表面之间的距离大于两个滑轨2之间的宽度。在滑轨2沿滑槽4滑动时，防脱件19可以避免第一转动件1从第二转动件3脱离，提高了转轴结构的稳定性。进一步地，防脱件19可以位于滑道远离弹性件8的一端，滑动件9可滑动地设置在滑道上，以使滑动件在防脱件19和弹性件8之间滑动。可见，防脱件19的设置还可以防止滑动件9从滑道脱离。
在一些可选的实施例中，上述转轴结构可以用于连接两个不同的功能件，从而使得第一转动件1和第二转动件3转动来带动两个不同的功能件转动。作为示例，上述转轴结构可以应用在头戴式电子设备中的，第一转动件1和第二转动件3可分别连接头戴式电子设备的镜框和镜腿，从而使得镜框和镜腿可以转动实现头戴式电子设备的展开佩戴和折叠收纳。本实施例公开的方案中，第一转动件1可以包括第一连接结构15，第一连接结构15可以用于连接第一功能件，如图1所示，第二转动件3可以包括第二连接结构16，该第二连接结构16可以用于连接第二功能件。本实施例公开的方案，使得转轴结构可应用到不同的产品中，扩大了转轴结构的适用范围。可以理解的是，本领域技术人员可以根据产品实际的需要来确定第一连接结构15和第二连接结构16的具体结构形式，这里没有具体地限定。作为示例，上述第一连接结构15、第二连接结构16可以为用于穿设螺栓等连接件的结构，或者上述第一连接结构15、第二连接结构16还可以是卡扣等卡接结构。
接下来请参考图9，其示出了根据本申请的头戴式电子设备的一个实施例的结构示意图。在本实施例中，头戴式电子设备可以包括如上的用于头戴式电子设备的转轴结构(如图9中虚线圈所示)、镜框12和镜腿13，如图9所示。上述镜框12可以称为头戴式电子设备的显示机身。上述转轴结构17中的第一转动件可以用于形成镜框12和镜腿13中的一种，第二转动件可以用于形成镜框12和镜腿13中的另一种。例如，第一转动件可以一体成型为镜腿13，第二转动件可以一体成型为镜框12，该头戴式电子设备中的镜腿13与镜框12之间通过第一转动件与第二转动件实现转动连接。
通常，头戴式电子设备中还可以包括多种电子元件，各电子元件可以分布在镜腿13和镜框12所形成的空腔中，不同的电子元件中可以通过数据线等电连接，数据线通常自镜框12延伸至镜腿13。上述数据线可以通过多种形式设置，例如，可以在镜框12和镜腿13的壳体上打孔，数据线通过外设的方式连接在镜框12上的孔和镜腿13上的孔之间。
在一些可选的实施例中上述转轴结构包括过线通道。上述数据线可以自镜框12穿过过线通道延伸至镜腿13。该数据线例如可以是FPC数据线，也可以是较粗的线缆，这里没有具体地限定。可以理解的是，上述转轴结构中的第一转动件1与第二转动件3配合形成有上述过线通道，具体结构可以参考上述转轴结构的实施例。在本实施例的方案中，上述数据线可由镜框12中引出，接着通过过线通道而进入镜腿13中。当然，也可以是由镜腿13中引出数据线，然后穿过过线通道而进入镜框12中。由于该过线通道朝外的一侧分别由转轴结构的第一转动件1及第二转动件3的底板、和侧板包围，故该数据线不会裸露在外，不仅保护了数据线的使用安全，而且提升了头戴式电子设备的美观度。
在一些可选的实施例中，上述第一转动件1可以包括第一连接结构15，用于连接镜腿13，如图10所示。例如，上述第一连接结构15可以是用于连接螺栓的螺孔，因此螺栓可以穿过螺孔将第一转动件1与镜腿13的壳体固定连接。类似地，上述第二转动件3可以包括第二连接结构16，用于连接镜框12，如图11所示。例如，上述第二连接结构15可以是用于连接螺栓的螺孔，因此螺栓可以穿过螺孔将第二转动件3与镜框12的壳体固定连接。可以理解的是，上述第一连接结构和第二连接结构具体结构不唯一，例如还可以为卡扣结构等。
在一些可选的实施例中，上述滑动件、滑道、防脱件中的一个或多个可以设置在镜腿13。例如，如图10所示，防脱件19为镜腿13壳体的一部分。可以理解的是，滑动件9、滑动和防脱件19与转轴结构中第一侧板等结构件的相对位置与上述实施例相同和类似，这里不再赘述。
在一些可选的实施例中，上述镜腿13在靠近第一连接结构15的一端设有第一卡件17，镜框12靠近第二连接结构的一端设有第二卡件18，如图12所示。上述第一卡件17和第二卡件18分别可以设置在镜腿13、镜框12的内侧，即用户佩戴头戴式电子设备时靠近用户皮肤的一侧。可以理解的是，上述镜腿13可以由内壳(用户佩戴时靠近用户皮肤一侧的壳体)和外壳构成，上述第一连接结构15固定在内壳、外壳所形成的腔体内，上述第一卡件17可以为镜腿13的内壳，如图12所示。或者，上述第一卡件17还可以为沿镜腿13的内壳设置的、与内壳分离的卡件。相应地，上述镜框12可以由前壳(用户佩戴时远离用户皮肤一侧的壳体)和后壳构成，上述第二连接结构16可以固定在前壳和后壳所形成的腔体内，上述第二卡件18可以为镜框12的后壳。或者，上述第二卡件18还可以为沿镜框12的后壳设置的卡件，如图12所示。在头戴式电子设 备处于折叠状态时，即镜框12与镜腿13处于折叠状态时，第一卡件17和第二卡件18相抵，如图12所示，从而可以防止镜腿13与镜框12过度折叠导致的镜框12与镜腿13分离。可以理解的是，上述头戴式电子设备还可以通过其他方式来控制折叠状态下镜腿13和镜框12所形成的角度，例如，镜腿13和镜框12折叠时，可以通过镜腿13远离转轴结构端和镜框12相抵(如图12的虚线圈区域所示，镜腿13和镜框12相抵)来控制镜腿13和镜框12所形成的角度。
在一些可选的实施例中，上述头戴式电子设备在展开状态下，镜腿13所形成的腔体和镜框12所形成的腔体相连接，如图13所示，从而可以将转轴结构和位于过线通道的数据线封闭在镜腿13和镜框12所形成的腔体内。此种状态下，转轴结构中的滑轨可以滑入滑槽中，从而使得第一转动件1和第二转动件3所成的角度可以大于或等于180度，如图14所示。可以理解的是，合理设置滑轨和滑槽的弧度可以控制头戴式电子设备展开状态下镜腿13和镜框12所成的角度，从而可以使得头戴式电子设备可以适用于不同脸型的用户。
相应地，上述头戴式电子设备在折叠时，转轴结构中的滑轨沿滑槽滑出的过程中，从而使得镜腿13的壳体和镜框12的前壳在外侧(用户佩戴时远离用户皮肤的一侧)会出现缝隙，且缝隙逐渐增大，直到如图15中的虚线圈所示。此种状态下，转轴结构中的滑轨滑入滑槽的部分最少，第一转动件1和第二转动件3的底板和侧板部分交叠位于镜腿13的壳体和镜框12的壳体外侧的缝隙处，从而使得镜腿13的外壳、镜框12的壳体和转轴结构在非内侧部分形成封闭结构，如图15的虚线圈处所示，从而避免数据线外漏。在折叠状态下，第一转动件1和第二转动件3所成的角度可以小于或等于90°，如图16所示，且滑轨至少部分在滑槽内。综上所述，包含本申请转轴结构的头戴式电子设备，在折叠和展开的状态下，数据线均不会外漏。
在一种可选的实施例中，针对上述头戴式电子设备的每个镜腿13，可以设置一个转轴结构。或者，针对上述头戴式电子设备的每个镜腿13，还可以设置两个转轴结构，且各转轴结构均可以形成有走线空间。具体地，针对同一镜腿13的两个转轴结构中的弧形滑轨(或弧形滑槽)所形成的弧形的相对设置，即弧形的弯曲方向相反。作为示例，可以在镜腿和镜框的内壳的内侧上固定一个转轴结构，在镜腿和镜框的外侧的内侧固定另一转轴结构。此种情况下，两个相对设置的转轴结构与镜腿和镜框相结合形成完全密闭的走线空间，数据线可以设置在走线空间中，靠近人体和原理人体的两侧均不会露线。本实施例的头戴式电子设备可以使得镜框和镜腿连接处的内外两侧均不露线。
在一个示例中，提供一种用于头戴式电子设备的转轴结构，包括：第一转动件，设有至少一个弧形滑轨；第二转动件，设有与各所述滑轨匹配的弧形滑槽，所述滑轨具有插入对应的所述滑槽内的配合部，所述配合部沿着所述滑槽可移动，以使所述第一转动件与所述第二转动件可转动地连接。
在一个示例中，提供一种头戴式电子设备，包括：镜框；镜腿；和将所述镜框和所述镜腿可转动地连接的转轴结构。
以上实施例仅为本申请的示例性实施例，不用于限制本申请。本领域技术人员可以在本申请的实质和保护范围内，对本申请做出各种修改或等同替换，这种修改或等同替换也应视为落在本申请的保护范围内。
