目前眼镜通常采用单轴转动，用于实现镜腿的折叠，方便收纳。但由于使用者的头型尺寸不同，对于单轴的眼镜会造成佩戴不舒服，影响用户的佩戴使用。特别是对于虚拟现实(VR)、增强现实(AR)、混合现实(MR)和扩展现实(XR)类眼镜，甚至在佩戴后会影响双目图像显示的清晰度。
相关技术中，有些眼镜的转轴能实现镜腿折叠的同时，还具有外翻功能，用于提供不同头宽尺寸的用户佩戴，以提高眼镜的舒适度。但是，对于不同头长、不同头型、不同鼻耳间距的用户来说，这种单轴外翻的眼镜仍然存在佩戴不舒适的情况。
基于上述构思和问题，本申请提出一种眼镜100，该眼镜100不仅能够实现镜腿2相对于镜框1的折叠收纳、正常佩戴以及外翻功能，还能够使得镜腿2相对于镜框1在另一方向上的转动调节，以使得眼镜100能够适用于不同头长、不同头型、不同鼻耳间距的用户佩戴，提高使用者的佩戴舒适性和通用性。
请结合参照图1至图14所示，在本申请实施例中，该眼镜100包括镜框1、镜腿2及铰链结构，镜框1设有安装槽11以及连通安装槽11的第一过孔13和第二过孔14，铰链结构包括旋转基座3、第一连接件4、第一弹性件5、第二连接件6及第二弹性件7，旋转基座3的一端活动容置于安装槽11内，且旋转基座3设有容置槽31以及连通容置槽31的第一转孔331、第二转孔321及滑动孔322，第二转孔321与第一过孔13对应，滑动孔322与第二过孔14对应，第一连接件4的一端通过第一转轴44与第一转孔331的孔轴配合与旋转基座3转动连接，第一连接件4的另一端与镜腿2连接，第一弹性件5的一端容置于容置槽31内，并设有与第一转轴44转动抵接的阻尼槽521，第一弹性件5的另一端与第一连接件4弹性抵接，第二连接件6设有间隔设置的第二转轴61和滑动轴62，第二转轴61依次转动穿设于第一过孔13和第二转孔321，以使旋转基座3与镜框1转动连接，且滑动轴62活动穿设于第二过孔14和滑动孔322，第二弹性件7设于镜框1内，并与旋转基座3弹性抵接；其中，第一转轴44的轴向方向与第二转轴61的轴向方向呈夹角设置。
在本实施例中，眼镜100可以是人们平时佩戴的近视眼镜、老花眼镜、散光眼镜、防晒眼镜以及装饰眼镜等，眼镜100还可以是智能眼镜，例如虚拟现实(VR)、增强现实(AR)、混合现实(MR)和扩展现实(XR)类眼镜等，在此不做限定。
可以理解的，眼镜100的镜框1设有与用户的两个眼睛对应的安装孔，两个安装孔可用于安装不同的镜片或智能光学系统等，在此不做限定。为了方便用户佩戴，镜框1在两个安装孔之间还设有用于与用户的鼻梁抵接的鼻托结构等，在此不做限定。
需要说明的是，为了方便用户佩戴眼镜100，眼镜100的镜框1通常与两个呈对称设置的镜腿2转动连接，使得用户通过镜框1的鼻托和两个镜腿2实现佩戴。当然，在其他实施例中，镜框1也可与头戴结构连接，以使头戴结构与镜框1围合形成环形佩戴空间等，特别是智能眼镜设备，因镜框1上安装有光学系统，导致镜框1整体比较重，为了方便佩戴并避免镜框1重量较大而掉落而设计头戴结构或头箍结构等，在此不做限定。
在本实施例中，眼镜100以镜框1与两个镜腿2配合的结构为例进行说明。为了方便镜框1与两个镜腿2连接，镜框1的两端设置有连接部或安装部。可以理解的，镜框1两端的两个连接部或安装部与镜框1的两个安装孔所在平面呈一定的角度设置，也即两个连接部或安装部大体由镜框1的两端朝向用户的耳部方向延伸形成。
需要说明的是，为了避免镜框1两端的两个连接部或安装部影响用户的佩戴，两个连接部或安装部的延伸长度较短，两个连接部或安装部的延伸长度可参照现有技术，在此不做限定。
在本实施例中，如图2和图3所示，镜框1两端的两个连接部或安装部分别设有安装槽11以及连通安装槽11的第一过孔13和第二过孔14，安装槽11用于容置和安装至少部分铰链结构，并利用铰链结构与镜腿2连接，如此使得镜腿2通过铰链结构与镜框1两端的连接部或安装部转动连接。
可以理解的，通过将铰链结构设置为旋转基座3、第一连接件4及第二连接件6，并在旋转基座3设有容置槽31以及连通容置槽31的第一转孔331、第二转孔321及滑动孔322，如此利用第一连接件4的一端通过第一转轴44与第一转孔331的孔轴配合与旋转基座3转动连接，第一连接件4的另一端与镜腿2连接，也即镜腿2通过第一连接件4和第一转轴44与旋转基座3配合实现转动连接，且旋转基座3的一端活动容置于安装槽11内，使得第二转孔321与第一过孔13对应，滑动孔322与第二过孔14对应，如此利用第二连接件6的第二转轴61依次转动穿设于第一过孔13和第二转孔321，且滑动轴62活动穿设于第二过孔14和滑动孔322，以使旋转基座3与镜框1转动连接，从而实现镜腿2通过铰链结构与镜框1转动连接。
需要说明的是，由于第一转轴44的轴向方向与第二转轴61的轴向方向呈夹角设置，也即镜腿2通过第一连接件4绕第一转轴44的轴向方向相对于旋转基座3和镜框1转动，且镜腿2通过旋转基座3绕第二转轴61的轴向方向相对于镜框1转动，从而实现镜腿2能够相对于镜框1在多个轴向方向进行多自由度转动，如此使得眼镜100能够适用于不同头长、不同头型、不同鼻耳间距的用户佩戴，提高使用者的佩戴舒适性和通用性。
在本实施例中，通过将第一弹性件5的一端容置于容置槽31内，并在第一弹性件5上设有与第一转轴44转动抵接的阻尼槽521，且第一弹性件5的另一端与第一连接件4弹性抵接，如此在镜腿2通过第一连接件4绕第一转轴44的轴向方向相对于旋转基座3和镜框1转动的过程中，使得镜腿2利用第一弹性件5在转动过程中形成摩擦阻尼，使镜腿2的运动过程中具有阻尼折叠手感的铰链运动，从而实现镜腿2的折叠，并使折叠具有阻尼手感以及提供外翻的夹持力效果。同时，通过将第二弹性件7设于镜框1内，并与旋转基座3弹性抵接，如此在镜腿2通过旋转基座3绕第二转轴61的轴向方向相对于镜框1转动过程中，利用第二弹性件7对旋转基座3绕第二转轴61的轴向方向转动提供抗变形的能力和防止出现过掰失效的问题。

在本实施例中，如图9至图11所示，通过在第一连接件4上设置限位部45，使得限位部45的两端分别连接于两个转动臂42远离第一连接部41的一端，从而利用限位部45在镜腿2通过第一连接件4绕第一转轴44相对于旋转基座3转动时可实现限位作用。
可以理解的，眼镜100具有第一连接件4带动镜腿2绕第一转轴44相对于旋转基座3和镜框1转动的折叠状态、打开状态及外翻状态；在折叠状态，镜腿2靠近镜框1，且第一连接部41远离第一弹性件5，限位部45靠近外翻弹片511；在打开状态，镜腿2远离镜框1，并与镜框1呈垂直设置，第一连接部41与外翻弹片511抵接，且限位部45远离外翻弹片511；在外翻状态，镜腿2与镜框1呈钝角设置，且第一连接部41带动外翻弹片511变形。
需要说明的是，眼镜100处于折叠状态，第一连接件4的转动臂42与旋转基座3的底板32大致呈垂直设置，此时限位部45靠近外翻弹片511。眼镜100处于打开状态，限位部45位于旋转基座3的侧板33远离底板32的一侧。眼镜100处于外翻状态时，第一连接件4的第一连接部41带动外翻弹片511变形至最大形变量时，限位部45与旋转基座3的侧板33限位抵接，以避免镜腿2的过度外翻。
在一实施方式中，眼镜100还包括保护板8和外壳9，保护板8容置于容置槽31内，并连接于第一弹性件5背向容置槽31底壁的一侧，保护板8背向第一弹性件5的一侧设有过线槽81，外壳9盖设于容置槽31的槽口，并与过线槽81配合形成走线通道91。
在本实施例中，如图2、图4、图9所示，通过设置保护板8和外壳9，从而利用保护板8为走线或连接眼镜100的光学系统的柔性电路板提供走线或安装空间。可以理解的，保护板8容置于容置槽31内，并通过紧固件依次将保护板8、第一弹性件5固定于旋转基座3的固定柱323上，从而实现保护板8的安装固定。
可以理解的，通过在保护板8背向第一弹性件5的一侧设有过线槽81，如此可方便利用过线槽81实现走线或柔性电路板的安装。在本实施例中，通过设置外壳9，一方面为了保护过线槽81内的线缆或柔性电路板，另一方面利用外壳9提高外观美观度。
可选地，外壳9可拆卸地盖设于容置槽31的槽口，并与过线槽81配合形成走线通道91。可以理解的，通过将外壳9与旋转基座3采用可拆卸连接方式，从而方便随时拆卸外壳9，方便在过线槽81内安装线缆或柔性电路板。
本申请的眼镜100主要涉及两个自由度的旋转轴，如图4所示的第一转轴44(轴A)和如图5和图6所示的第二转轴61(轴B)，轴A用于实现镜腿2的折叠功能、打开功能和外翻功能。可以理解的，折叠功能用于实现镜腿2的折叠收纳，外翻功能用于满足不同头宽用户佩戴的舒适度调节。轴B用于实现镜腿2的侧向调节功能，轴B具有三档调节功能，用于满足不同头型、不同鼻耳比例的用户佩戴舒适度调节。
可以理解的，如图10所示，是铰链结构的组成示意图，可将第一连接件4、旋转基座3、第一弹性件5通过第一转轴44提前组装到一起作为一个整体模组。然后将第二连接件6、第二弹性件7、保护板8和外壳9依次组装完成。
本实施例中的第一连接件4、旋转基座3、第一弹性件5通过第一转轴44组装为铰链模组，通过第一连接件4与镜腿2通过螺钉、粘接等固定形式刚性连接到一起。该铰链模组通过第二连接件6的第二转轴61依次穿过镜框1上的第一过孔13与铰链模组的旋转基座3通过固定件64连接固定，且将第二弹性件7固定在镜框1上，使得旋转基座3的档位凸起332与第二弹性件7的档位槽711相互配合实现铰链模组与镜框1的连接。铰链模组用于实现镜腿2的轴A运动和外翻力值提供，通过铰链模组通过第二连接件6和第二弹性件7的配合与镜框1组装后，用于实现镜腿2的侧向运动和力值提供(也即轴B)。如图4和图8所示，轴A用于实现折叠和外翻旋转运动；如图5、图6和图7所示，轴B用于实现镜腿2的侧轴调节功能。
可以理解的，眼镜100的镜腿2与镜框1可实现外翻和折叠阻尼感的铰链连接。当转动镜腿2时就会带动第一连接件4进行转动，旋转基座3与镜框1固定，第一弹性件5是具有较好弹性的金属板材，第一弹性件5上的外翻弹片511用于外翻时提供夹持力和外翻力撤销后的自动回弹，第一弹性件5的阻尼支臂52的阻尼槽521用于镜腿2转动过程中提供阻尼力，让运动过程中有一定的阻尼感；第一转轴44是具有不同截面的销轴，其中两端是扁轴，用于与第一连接件4刚性的固定在一起，例如采用过盈、点焊、粘接等方式，第一转轴44与旋转基座3的固定是可以转动的圆孔圆柱配合，形成旋转中心轴A，用于两者的相互转动。所以当折叠镜腿2时，镜腿2会带动第一连接件4向内，通过第一转轴44与旋转基座3形成折叠运动，第一转轴44与第一连接件4一起进行转动，第一转轴44的转动会与第一弹性件5的阻尼槽521形成摩擦阻尼，使运动过程中具有阻尼折叠手感的铰链运动，从而实现镜腿2的折叠，并使折叠具有阻尼手感。
当外翻镜腿2时，满足不同头宽的用户佩戴时，镜腿2会带动第一连接件4向外转动，转动的第一连接件4会带动第一弹性件5上的外翻弹片511弹性变形，从而产生推动第一连接件4向内转动的扭矩，从而提供加持力，当撤销外翻的外力后，弹性变形外翻弹片511会推动第一连接件4带动镜腿2回到弹片的原始状态，从而实现撤销外翻力后，镜腿2能自动回弹到原始位置。
可以理解的，眼镜100的镜腿2与镜框1还可实现侧轴调节的结构方案，用于实现镜腿2与镜框1之间的角度调节，满足不同头型用户的佩戴。第二连接件6从镜框1内侧，使得第二转轴61穿过镜框1对应的第一过孔13，再穿过旋转基座3上对应的第二转孔321，最后通过固定件64固定。由于第二连接件6的三个滑动轴62与镜框1上对应的第二过孔14进行定位，再通过固定件64的固定，从而实现第二连接件6与镜框1的完全固定；旋转基座3与第二连接件6通过圆柱(第二转轴61)和圆孔(第二转孔321)配合，旋转基座3的第二转孔321和旋转筒325与第二连接件6的第二转轴61形成旋转中心轴B，从而铰链模组带动镜腿2可以沿着旋转中心轴B与镜框1以及第二连接件6进行相互转动。由于旋转基座3的档位凸起332与第二弹性件7上的档位槽711有对应的位置限制凸台和凹槽，镜腿2可以停留在任何一个凹槽(即档位槽711)中，当沿着侧向转动镜腿2后，档位凸起332压动第二弹性件7的档位槽711进行弹性变形，当档位凸起332转动到相邻档位槽711的分解线后，第二弹性件7的弹性变形回复，并推动档位凸起332转动到相邻的档位槽711中，完成镜腿2与镜框1的角度调节，转动后的示意图如图5和图6所示。
其中，滑动轴62可以在旋转基座3上面对应的滑动孔322内做滑动，同时起到在扭转镜腿2的时候可以加强抗变形的能力，同时防止出现过掰失效的问题。其中第二弹性件7的形状可以是平板形的，也可以是U形或其他形状的，第二弹性件7的材料可以不锈钢材质，不锈钢材质包括钛合金、镍钛合金、铍铜等材料；或，第二弹性件7的材料也可以碳纤维等复合材料。可选地，第二弹性件7的弹性模量可以是50Gpa～400Gpa。通过调节第二弹性件7上档位槽711上的间距和角度，可以改变镜腿2的调节角度在1度±30度范围内变动。
本申请还提出一种AR设备，该AR设备包括光学系统和上述的眼镜100，光学系统连接于眼镜100的镜框1。该眼镜100的具体结构参照前述实施例，由于本AR设备采用了前述所有实施例的全部技术方案，因此至少具有前述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
在本实施例中，AR设备包括柔性电路板，柔性电路板的一端穿设于走线通道91并与光学系统电连接。可以理解的，眼镜100的镜腿2内设有用于安装电源的安装腔等结构，柔性电路板的另一端经由走线通道91引导至镜腿2的安装腔内与电源等部件电连接，在此不做限定。
可以理解的，AR设备可以是虚拟现实(VR)、增强现实(AR)、混合现实(MR)和扩展现实(XR)类眼镜，在此不做限定。
