本申请提出一种镜腿连接结构。可以理解，该镜腿连接结构适用于连接各类眼镜的镜框和镜腿，下面实施例以头戴显示设备为例，但本申请的镜腿连接结构的应用不限于头戴显示设备。
请参阅图1至图3，在本申请一实施例中，该镜腿20连接结构用以连接镜腿20和镜框10，其中，镜框10的延伸方向为K，镜腿20的延伸方向为T，所述镜腿20连接结构包括：
相互转动连接的第一支架100和第二支架200，所述第一支架100用以固定连接所述镜框10，所述第二支架200用以固定连接所述镜腿20；
活动件300，可活动地安装于所述第一支架100，并连接于所述第二支架200；以及
第一弹性件410，设于所述第一支架100和所述活动件300之间，并与所述活动件300可分离地设置；
所述第二支架200自打开位置内折时，所述弹性件与所述活动件300分离；
所述第二支架200自所述打开位置外翻时，所述第一弹性件410的两端分别抵持所述活动件300和所述第一支架100，所述第二支架200能受到所述弹性件经由所述活动件300传递的弹性力从而为所述镜腿20提供夹持力。
可以理解，第一弹性件410对活动件300和第一支架100的抵持，可以是直接抵接或间接抵接或嵌接连接，使得第一弹性件410能够对活动件300和第一支架100传递弹性力。
本申请的技术方案中，第二支架200具有折叠位置和打开位置，镜腿20固定连接于第二支架200，在第二支架200处于折叠位置时，镜腿20处于折叠状态，与镜框10相叠设，在第二支架200处于打开位置时，镜腿20处于打开状态，镜腿20和镜框10大致呈90度。
当头围较大的用户佩戴头戴显示设备时，镜腿20会相较打开状态向外翻，第二支架200也对应地从打开位置外翻，由此能使活动件300受到第一弹性件410抵持的弹性力，同时，第二支架200作用在活动件300上，第二支架200也即能受到活动件300所传递的来自第一弹性件410的弹性力，如此，第一弹性件410的弹性力能够为镜腿20提供额外的夹持力，由此提升了镜腿20对用户头部的夹持力，从而提升了头戴显示设备的佩戴稳定性。
进一步地，在打开位置时，第一弹性件410可以处于自然状态，第二支架200自打开位置外翻时，通过作用于活动件300，使得第一弹性件410的弹性形变慢慢增加，镜腿20的夹持力也随之逐渐增加；在打开位置时，第一弹性件410也可以处于弹性形变状态，如此，在第二支架200的外翻幅度很小时，第二支架200即可通过和活动件300之间的配合，接受来自第一弹性件410比较大的弹性力，从而使得镜腿20具有足够大的夹持力。
可以理解，在第一弹性件410能够在镜腿20外翻时提供夹持力的前提下，若要使第一弹性件410在镜腿20内折时，同样能够起到协助的效果，会增大镜腿20连接结构的设计难度，且第一弹性件410容易失效。本申请技术方案中，当用户折叠镜腿20时，第一弹性件410脱离于活动件300，第一弹性件410的弹性力无法再向第二支架200传递，也即不会干涉第二支架200内折，有利于保障镜腿20折叠的顺畅性。
具体而言，第一弹性件410可以是拉簧或压簧，也可以是弹片、碟簧、扭簧、变径弹簧、空气压缩弹簧等弹性体。
进一步地，如图3至图5所示，本实施例中，所述活动件300包括连杆330和通过所述连杆330连接的第一滑动件310和第二滑动件320，所述第一支架100设有第一滑槽110和第二滑槽120，所述第一滑动件310滑动连接于所述第一滑槽110，所述第二滑动件320滑动连接于所述第二滑槽120，所述第二支架200连接于所述第一滑动件310，所述第一弹性件410设置于所述第一支架100和所述第二滑动件320之间。需要说明的是，本实施例中，第一滑槽110配置为如图3所示的盲槽形式，图5至图8中，第一支架100上具有的弧形通孔，均是为了清楚显示第一滑动件310及其他相关结构与第一滑槽110的配合，该弧形通孔并非第一支架100上所固有的结构。
如此，第二支架200驱动第一滑动件310沿第一滑槽110运动时，能够通过连杆330带动第二滑动件320在第二滑槽120内滑动。在镜腿20外翻时，第二滑动件320在第二滑槽120内滑动时，能作用在第一弹性件410上，第一弹性件410的弹性力能依次经由第二滑动件320、连杆330及第一滑动件310传递到第二支架200上，从而为镜腿20提供夹持力。也即，在本实施例中，第二支架200直接作用在第一滑动件310上，第一弹性件410直接作用在第二滑动件320上，第一弹性件410的作用力在活动件300的内部间接地通过连杆330传递，如此，能使得活动件300的受力比较分散，有利于保障活动件300的结构稳定性，并且，第一滑动件310和第二滑动件320能够分别兼顾第二支架200和第一弹性件410的位置，第二支架200转动过程中所引发的第一滑动件310和第二滑动件320之间的位移，则可由连杆330进行弥补。当然，在其他实施例中，也可以是，活动件300采用其他形式的结构，在活动件300的结构强度满足要求的前提下，第二支架200对活动件300的作用力和第一弹性件410对活动件300的作用力集中在同一部位也可。
具体而言，所述第一滑动件310和/或第二滑动件320对应地可转动连接于所述连杆330的端部。也即，第一滑动件310和第二滑动件320中的至少一者和连杆330可转动连接，如此，第一滑动件310和第二滑动件320能够更自由地在对应的滑槽内滑动，且连杆330和滑动件之间的应力很小，连杆330和滑动件的连接处不容易断裂，有利于保障活动件300的结构稳定性。
具体而言，所述第一滑动件310、所述连杆330、所述第一滑槽110和所述第二滑槽120对应地设置为两个，一所述第一滑动件310对应地连接于一所述第一滑槽110，所述第二滑动件320的两端分别连接于一所述第二滑槽120，一所述连杆330对应地连接于一所述第一滑动件310和所述第二滑动件320的其中一端，两所述第一滑动件310间隔设置，以供所述镜腿20和所述镜框10之间的电连接件600穿设。也即，活动件300在相对两侧分别和第一支架100的两侧壁配合，且第一滑动件310和第二滑动件320之间通过两个连杆330配合，如此，能够提升活动件300的结构稳定性，以及活动件300和第一支架100的配合稳定性。在此基础上，第一滑动件310设置为相间隔的两个，给镜腿20和镜框10之间的电连接件600提供了过线空间，且该过线空间在镜腿20折叠后也能稳定地存在，能够保障电连接件600在镜腿20连接处不会受到挤压，有利于保障镜框10和镜腿20之间的电连接及信号传输的稳定性。
进一步地，在本实施例中，如图2和图5所示，所述第一支架100设有限位凸部130，于所述打开位置，所述第一弹性件410抵持于所述限位凸部130；所述第二支架200自所述打开位置外翻时，能带动所述第二滑动件320抵压所述第一弹性件410远离所述限位凸部130；所述第二支架200自所述打开位置内折时，能带动所述第二滑动件320远离所述第一弹性件410。可以理解，限位凸部130在第一弹性件410和第二滑动件320的分布方向上对第一弹性件410起到限位作用。不失一般性，第一弹性件410设置为压簧，在打开位置，第一弹性件410的同一端同时抵持在限位凸部130和第二滑动件320上，另一端则抵持在第二支架200上。第二支架200自打开位置逐渐外翻时，第二滑动件320将朝向第一弹性件410所在侧活动，从而抵压第一弹性件410，使第一弹性件410逐步发生压缩，第一弹性件410的弹性势能也逐步累积。可以理解，镜腿20外翻角度越大，头戴显示设备脱落的风险越大，本实施例通过第一弹性件410提供更大的夹持力，能够有效保障头戴显示设备的佩戴稳定性。此外，在镜腿20外翻后，若不受到外力作用，第一弹性件410将释放弹性势能，从而促使第二支架200回复至打开位置，头戴显示设备也就不会维持在镜腿20外翻的姿态。第二支架200自打开位置内折时，第二滑动件320也即朝反方向运动，由此能够逐渐远离第一弹性件410，使得第一弹性件410和第二支架200之间解耦，第二支架200也即不会受到第一弹性件410的作用力。
本实施例中，在打开位置，通过限位凸部130对第一弹性件410限位，使得第一弹性件410在打开位置也可具备一定的压缩量，如此，在第二支架200的外翻幅度很小时，第二支架200即可接受来自第一弹性件410比较大的弹性力，从而使得镜腿20具有足够大的夹持力。当然，在其他实施例中，也可以是，在打开位置，第一弹性件410处于自然状态，如此，在第二支架200内折时，第二滑动件320也能与第一弹性件410分离。
进一步地，在本实施例中，如图2、图3和图5所示，所述镜腿20连接结构还包括安装件500，所述安装件500位于所述第一弹性件410和所述第二滑动件320之间，所述第一弹性件410安装于所述安装件500，于所述打开位置，所述安装件500抵接于所述限位凸部130。可以理解，在第二支架200处于打开位置时，安装件500还将抵接于第二滑动件320，如此，第一弹性件410能够通过安装件500间接抵接于限位凸部130和第二滑动件320，当第二支架200自打开位置外翻时，第二滑动件320通过抵推安装件500，从而间接地抵压第一弹性件410。本实施例中，安装件500能够为第一弹性件410提供稳定的安装环境，使得第一弹性件410不容易移位。当然，在其他实施例中，也可以是，第一弹性件410的端部直接抵接于第二滑动件320及限位凸部130。
具体而言，所述安装件500的横截面呈背向所述第二滑动件320凸设的弧形，在所述打开位置，所述第二滑动件320可分离地卡合于所述安装件500。也即第二滑动件320与安装件500抵接配合的外壁面的形状是相适配的弧形，能够在一定程度上增加二者的受力面，减小二者之间的作用压力，同时提升二者受力均匀性，有利于保障第二滑动件320和安装件500的抵接配合的稳定性。当然，在其他实施例中，也可以是，安装件500和第二滑动件320通过其他形状的表面卡合配合，亦或者，在安装件500或者第二滑动件320相抵接的任意表面设置弹性垫，以起到缓冲作用。
具体而言，所述安装件500凸设有安装凸部510，所述第一弹性件410套设于所述安装凸部510。如此，安装件500能够供第一弹性件410稳定装设，第一弹性件410不容易从安装件500上脱落，也即能够稳定地处于第一支架100和活动件300之间。此外，第一弹性件410可以设置一个或多个，安装凸部510对应第一弹性件410的数目设置，第二弹性件420远离安装件500的一端则直接抵接在第一支架100的壁体上。当然，在其他实施例中，也可以回，安装件500上凹设有安装孔，第一弹性件410的端部容置于安装孔内。
进一步地，在本实施例中，如图3所示，所述第一滑槽110呈弧形，所述第二滑槽120呈直线型。如此，具体地，第二支架200相对第一支架100转动时，第一滑动件310在弧形的第一滑槽110内运动，能够很好地跟随第二支架200，第二滑槽120呈直线型，加工简单，同时，第二滑动件320在第二滑槽120内滑动，能够满足第二滑动件320跟随第一滑动件310。本实施例中，第一滑动件310和第二滑动件320分别在上述形状的第一滑槽110和第二滑槽120内滑动，活动件300的运动将类似曲柄滑块机构的运动。更进一步地，所述第二滑槽120的长度方向与所述第一弹性件410的轴向并行，且所述第二滑槽120在宽度方向上与所述第一弹性件410相对设置。可以理解，第二滑动件320将沿第二滑槽120的长度方向在第二滑槽120内滑动，本实施例中，第一弹性件410的轴线将重合或近似重合于第二滑槽120的对称轴线，使得第二滑动件320对第一弹性件410的作用力方向能够和第一弹性件410的弹性力处于或近似处于同一直线上，第二滑动件320能够更有效地抵压第一弹性件410，并且，第一弹性件410在压缩后，受到的各个力的同轴性高，使得第一弹性件410不容易在径向上发生偏移，有利于保障第一弹性件410的安装稳定性。当然，在其他实施例中，第一滑槽110和第二滑槽120可以设置为其他形状，其中，第一滑槽110和第二滑槽120可以是延伸方向不同的同一形状类型的槽结构。
进一步地，如图2所示，在本实施例中，所述镜腿20连接结构还包括第二弹性件420，所述第二弹性件420连接在所述活动件300和所述第二支架200之间，在所述支架自折叠位置向打开位置切换的过程中，所述第二弹性件420的弹性形变量先变大后变小。也即，在折叠位置和打开位置之间的一个中间位置(为方便后文描述，称其为最大弹性位置)，第二支架200受到的弹性力最大，而弹性件在折叠位置或打开位置受到的弹性件，都小于其在该中间位置受到的弹性力。如此，在第二弹性件420的作用下，在折叠状态和打开状态下，镜腿20不受到外力时，能维持自己的当前状态，避免镜腿20自开合。并且，在第二弹性件420的弹性形变量达到最大的位置时，若镜腿20具备一个朝向折叠的方向或打开的方向的初速度，在第二弹性件420的作用下，镜腿20后续不受力，也能对应折叠或打开，也即能够实现弹弓效果，提升打开镜腿20或折叠镜腿20的操作便利性。不失一般性，在打开位置和折叠位置，第二弹性件420均处于自然状态，在镜腿20相对镜框10的打开角度大致在45度时，达到最大弹性位置。其中，第二弹性件420可以是拉簧或压簧，也可以是弹片、碟簧、扭簧、变径弹簧、空气压缩弹簧等弹性体。
进一步地，在本实施例中，请一并参阅图5至图9，所述第一滑槽110和所述第二滑槽120的最小距离为所述第一滑槽110的第一位置103和所述第二滑槽120的第二位置之间的距离，所述连杆330的长度大于所述最小距离；所述第一位置103位于所述第一滑槽110的两端之间，于所述打开位置和所述折叠位置，所述第一滑动件310分别位于所述第一位置103的两侧；所述第二位置位于所述第二滑槽120的一端，所述第二滑槽120的另一端朝远离所述第一位置103的方向延伸，所述第二弹性件420抵接于所述滑动件背离所述第二位置的一侧。
为方便描述，称第一滑槽110的两端分别为第一端101和第二端102，第二滑槽120的两端分别为第三端121和第四端122，第一滑槽110的第一位置103处于第一端101和第二端102之间，第二滑槽120的第二位置处于第三端121，另外，需要说明的是，滑动件更靠近对应的滑槽的某端，是指相对该滑槽的另一端而言，也即，滑动件与对应的滑槽的某端之间的距离小于其与另一端之间的距离，即称滑动件更靠近某端。
本实施例中，如图5和图6所示，在第二支架200处于打开位置时，第一滑动件310处于位于第一端101和第一位置103之间，第二滑动件320则靠近第三端121设置，且与第三端121之间留有一定间距。
当第二支架200自打开位置外翻时，第一滑动件310将朝向第一端101滑动，第二滑动件320被带动，将朝向第三端121移动，由此抵压第一弹性件410，从而通过第一弹性件410的弹性力为镜腿20提供夹持力。不失一般性，如图9所示，当第二支架200到达外翻最大位置，第一滑动件310可以抵接于第一端101的端壁，第二滑动件320可以对应抵接于第三端121的端壁，以提供定位作用以及限位脱出的作用。
请一并参阅图6至图8，而当第二支架200自打开位置内折时，第一滑动件310将朝第二端102滑动，在第一滑动件310到达第一位置103之前，第二滑动件320将被抵推朝向第四端122滑动，第二滑动件320脱离第一弹性件410的抵持，而开始抵压第二弹性件420，使得第二弹性件420的弹性形变量逐渐增大。当第一滑动件310到达第一位置103时，第二滑动件320到达距离第四端122最近的位置，其中，第二滑动件320可以抵接在第四端122的端壁上，此时，第二弹性件420的弹性形变量达到最大，第二支架200也对应到达最大弹性位置。当第一滑动件310自第一位置103继续向第二端102滑动时，第二滑动件320将被拉动，而反向朝第三端121的方向滑动，此时，第二滑动件320对第二弹性件420的抵压力减弱，第二弹性件420逐渐恢复形变，直至镜腿20折叠完成，第二支架200处于折叠位置时，第一滑动件310将运动至最靠近第二端102的位置，其中，第一滑动件310可以到达第二端102的位置。
如此，依赖本实施例中的第一滑槽110和第二滑槽120的相对位置关系，能够很好地通过第一弹性件410在镜腿20外翻时提供夹持力，在镜腿20内折时，提供弹弓效果。
更进一步地，所述第二滑槽120的长度方向与所述第二弹性件420的轴向并行，且所述第二滑槽120在宽度方向上与所述第二弹性件420相对设置。如此，第二弹性件420的轴线将重合或近似重合于第二滑槽120的对称轴线，使得第二滑动件320对第二弹性件420的作用力方向能够和第二弹性件420的弹性力处于或近似处于同一直线上，第二滑动件320能够更有效地抵压第二弹性件420，并且，第二弹性件420在压缩后，受到的各个力的同轴性高，使得第二弹性件420不容易在径向上发生偏移，有利于保障第二弹性件420的安装稳定性。具体而言，第一弹性件410和第二弹性件420沿第二滑槽120的长度方向分布在第二滑动件320的相对两侧，第一支架100对应第二弹性件420设置抵接凸部140，第二弹性件420容置在抵接凸部140和第二滑动件320之间，第二弹性件420的端部可以采用嵌接的方式和抵接凸部140相连接。其中，可以是第一支架100形成有延长臂，抵接凸部140设置在延长臂的末端，镜腿20对应延长臂设置避让槽，也可以是，镜腿20的端部对应抵接凸部140的位置设置，如此，均可避免镜腿20在转动过程中受到第一支架100的干涉。
进一步地，在本实施例中，所述第二支架200设有滑动凸部211，并可转动地连接于所述第一滑动件310，所述滑动凸部211避让所述第一滑动件310设置，并可滑动地连接于所述第一滑槽110，而使所述第一滑槽110的圆心成为所述第二支架200相对所述第一支架100转动的转动中心。具体地，第二滑槽120分布在靠近镜腿20的一侧，第一滑槽110呈朝向第二滑槽120凸设的弧状。镜腿20相对镜框10转动，能带动滑动凸部211沿第一滑槽110滑动，由此使得第二支架200绕第一滑槽110的圆心转动，滑动凸部211和第一滑动件310互相避让，能够一前一后地在第一滑槽110内滑动，第二支架200和第一滑动件310的转动配合，能够很好地抵消二者相对位置的变化。当然，在其他实施例中，也可以是，第二支架200通过转轴可转动地连接于第一支架100。
进一步地，在本实施例中，所述滑动凸部211设置为与所述第一滑槽110适配的弧形，所述第一滑槽110的端部设有避让缺口104，在所述第二支架200处于折叠位置时，所述滑动凸部211的部分自所述避让缺口104伸出。也即，在镜腿20折叠到位后，滑动凸部211的部分伸出到第一滑槽110外，其余部分仍处于第一滑槽110内，如此，一方面，能够避免滑动凸部211脱出第一滑槽110，另一方向能够封堵避让缺口104，避免第一滑动件310自避让缺口104脱出。
进一步地，在本实施例中，如图3和图4所示，所述第二支架200包括相间隔设置的两支臂210，所述第二支架200通过所述支臂210可转动地连接于所述第一滑动件310，两所述支臂210伸入到所述第一支架100内，两所述支臂210的相背侧均设有所述滑动凸部211，所述第一支架100对应设置两个所述第一滑槽110，一所述滑动凸部211对应地滑动连接于一所述第一滑槽110。具体地，一个支臂210对应地可转动连接于一个第一滑动件310，同时，两个支臂210能够分别和两个第一滑槽110配合，以提升第二支架200转动的稳定性。其中，两个支臂210之间的间隔不会干涉镜框10和镜腿20之间的电连接件600的通过，配合于两个第一滑动件310之间的间隔，如此，本实施例的镜腿20连接结构能够给电连接件600提供较大的弯折半径，减少电连接件600的弯折风险，提高头戴显示设备的弯折使用寿命。
