技术领域
本申请涉及穿戴类智能设备技术领域，特别涉及一种智能眼镜。
背景技术
目前，在头戴显示设备产品领域，大多数产品为了减轻产品的重量，越来越多地设置为眼镜形态的智能眼镜。智能眼镜内部空间狭小，能够利用的空间都被布置上了相关硬件。其中，主控制板部分因为体积相对较大一般都布置在镜框侧，这就导致镜框侧的发热量很大，影响用户的体验，而镜腿侧多布置音频、电池或充电接口等，发热量较小。
现有的一些智能眼镜中，镜腿部分具有可折叠功能，但采用的是一个常规的转轴，镜腿相对于该转轴自由活动。但是，在佩戴状态下，由于使用者头部大小是不一样的，有些使用者佩戴时容易脱落。
因此，如何提高智能眼镜佩戴的可靠性，是本领域技术人员目前需要解决的技术问题。

有鉴于此，本申请的目的是提供一种智能眼镜，其佩戴的可靠性较高。
为实现上述目的，本申请提供如下技术方案：

优选地，相邻所述连接板之间设有板件限转结构，以限制相邻两个所述连接板可相对转动的角度。
优选地，所述连接板为至少三个，所述铰链组件还包括固定套接于前后两端所述连接板之间的各所述连接板外的铰链套。
优选地，相邻所述连接板通过定位销转动连接；对于套设有所述铰链套的所述连接板，其上至少一个所述定位销沿轴向伸出于所述连接板并插接于 其外所述铰链套上；所述铰链套的内表面上在轴向上的两端、在佩戴状态下靠近和远离头部的两端分别设置有套限位块，以与所述连接板的外表面对应相抵。
优选地，所述铰链套内的前端设有开口向前的C型槽，所述铰链套能够由后至前套设于对应的所述连接板外，直至所述C型槽与所述连接板前端的所述定位销对应扣接。

通过在铰链组件中增设弹性组件，能够使得佩戴状态下，两个镜腿可以夹持头部，避免佩戴状态下的智能眼镜掉落，提高佩戴的可靠性。另外，由于弹性组件在镜腿外翻预设转角后才开始形变，而在预设转角之内是不形变的，可以使得弹性组件在较不适宜佩戴的转角下处于不形变的松弛状态，有利于延长弹性组件的使用寿命。

本申请的核心是提供一种智能眼镜，其佩戴的可靠性较高。
需要说明的是，当元件被称为“固定”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。在本申请的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件 必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”、“第三”、“第四”仅用于描述目的，而不能理解为指示或暗示相对重要性。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。
本申请所提供智能眼镜的具体实施例一中，请参考图1至图20，包括镜框2和镜腿6。镜腿6中设有控制组件，镜框2中设有主控板21，控制组件通过电连接件5电连接于主控板21。具体地，电连接件5包括FPC51和cable线束52。
镜腿6通过铰链组件转动连接于镜框2，以使镜腿6能够相对于镜框2内折或者外翻。具体地，在智能眼镜中，两个镜腿6分别通过对应的铰链组件连接于镜框2。
铰链组件包括设置在铰链壳4内的弹性组件。镜腿6相对于镜框2外翻且转角大于预设转角后，弹性组件弹性形变以使镜腿6具有内折转动的运动趋势，而在镜腿6相对于镜框2外翻且转角不大于预设角度时，弹性组件处于原状。
具体请参考图5至图7，线K为镜框2所在直线，线T为镜腿6所在直线，图6为镜腿6处于预设临界位置时的状态，向上为外翻方向，向下为内折方向，图5为镜腿6处于预设外翻极限位置时的状态，图7为镜腿6处于预设内折极限位置时的状态。可选地，图5中，镜腿6与镜框2之间转角为B1；图6中，镜腿6与镜框2之间转角为B0，0＜B0＜B1，B0即为预设转 角，更具体地，B0＜90°；图7中，镜腿6与镜框2之间转角为0，两者相平行。
在佩戴过程中，使用者外翻镜腿6，在镜腿6由如图7所示状态外翻至图6所示状态的过程中，弹性组件在各位置保持不形变的原状，而由图6所示状态翻转至图5所示状态的过程中，弹性组件在各位置均处于形变状态，相应地，弹性组件的复位力使得镜腿6具有内折的运动趋势，佩戴后，头部位于图5方位下镜腿6的上侧，镜腿6能够为头部提供夹持力。
其中，预设临界位置的设置可以结合人体尺寸的大数据进行分析设置，使得多数使用者在佩戴时，镜腿6均能够提供夹持力。
本实施例中，通过在铰链组件中增设弹性组件，能够使得佩戴状态下，两个镜腿6可以夹持头部，避免佩戴状态下的智能眼镜掉落，提高佩戴的可靠性。另外，由于弹性组件在镜腿6外翻预设转角后才开始形变，而在预设转角之内是不形变的，可以使得弹性组件在较不适宜佩戴的转角下处于不形变的松弛状态，有利于延长弹性组件的使用寿命。
进一步地，如图20所示，铰链组件还包括至少两个由前至后依次设置的连接板31，最前端连接板31连接于镜框2，最后端连接板31连接于镜腿6，具体地，最前端连接板31插装并螺钉固定于镜框2，最后端连接板31插装并螺钉固定于镜腿6，固定稳定可靠，螺钉数量可设置至少两个。
其中，需要说明的是，如无特殊说明，在镜框2和镜腿6之间，前、后是以镜框2、镜腿6的位置为基准进行界定的，镜框2在前而镜腿6在后，例如，对于连接板31，其靠近镜框2的一端为前端，而靠近镜腿6的一端为后端。
另外，弹性组件包括设于每相邻两个连接板31之间的弹性件，使得不同弹性件配合完成弹性组件的整体形变，各连接板31分别承担一部分弹性压力，有利于延长铰链组件的使用寿命。本实施例中，连接板31设置4个，当然，在其他实施例中，连接板31也可以为两个或者其他数量。
进一步地，请参考图3，弹性件为弹片32，便于加工。具体地，弹片32位于连接板31在佩戴状态下远离头部的一侧。弹片32的一端固定于其中一个连接板31上，另一端为自由端且通过与另一个连接板31相抵以形变。
显然，在其他实施例中，弹性件也可以为套设在两个连接板31之间连接轴343上的扭簧。
进一步地，连接板31与弹片32为分体式结构。如图3所示，弹片32螺钉固定于对应的连接板31上，便于弹片32的更换与维修。由于弹片32和连接板31的分体式设置，可以降低对连接板31的弹性要求，连接板31有没有弹性均可，具体可以根据实际使用所需强度选用适合的不锈钢材料，可防止生锈，另外，弹片32可以选用弹性性能较好的不锈钢304或不锈钢301。
进一步地，每相邻两个连接板31中，其中一者在轴向上的中部固定弹片32，另一者在轴向上的中部设有弹片槽37，弹片32通过伸入于弹片槽37并与弹片槽37的槽底相抵以形变。如图5所示，弹片槽37的槽底构成与弹片32的自由端挤压配合的挤压面33，以供与弹片32的自由端相抵，通过单独设置弹片槽37，可以保证镜腿6处于预设内折极限位置的状态下，弹片32的自由端与挤压面33之间具有足够大的距离，从而确保镜腿6的状态由图7向图6变化的过程中，弹片32的自由端与挤压面33能够保持分离状态，弹片32不会挤压到挤压面33而形变。
进一步地，相邻连接板31之间设有板件限转结构，以限制相邻两个连接板31可相对转动的角度。具体地，如图4和图7所示，在相邻两个连接板31中，板件限转结构包括后一个连接板31的前端面上沿着佩戴状态下远离头部的方向依次设置的板件内折限位面381和板件外翻限位面382，便于加工。如图7所示，后一个连接板31可内折转动至其上板件内折限位面381与前一个连接板31的后端面相抵，以限定相邻两个连接板31之间可内折转动的最大角度，避免单节连接板31转动角度过大导致镜框2和镜腿6之间电连接件5的各部分弯折角及弯折半径过大。如图4所示，后一个连接板31可外翻转动至其上板件外翻限位面382与前一个连接板31的后端面相抵，以限定相邻两个连接板31之间可外翻转动的最大角度，各连接板31的转动具有弯折半径大、可弯折的最大角度小的特征。
进一步地，铰链组件包括铰链壳4，铰链壳的两端分别铰接于镜框2和镜腿6，铰链壳包括若干个铰链套41，铰链套41为沿前后方向贯穿设置的环形套。具体地，连接板31为至少三个，铰链组件还包括固定套接于前后两端连接板31之间的各连接板31外的铰链套41。如图10所示，本实施例中，连接板31为4个，中间的两个连接板31外各固定连接一个铰链套41。
其中，优选地，电连接件5由镜腿6穿过铰链壳4内部后伸入镜框2中。通过将电连接件5内置于铰链壳4中，能够降低电连接件5的裸露程度，对电连接件5进行有效防护，降低电连接件5的损坏风险。
本实施例中，各铰链套41与其内连接板31是固定连接、同步转动的，能够避免连接板31在铰链套41中随意晃动而与铰链套41内的电连接件等部件发生碰撞。
另外，镜框2与最前端连接板31之间、镜腿6与最后端连接板31之间分别通过螺钉连接、焊接连接或者铆接连接等方式相固定，固定稳定可靠。由于铰链套41固定连接于其内连接板31上，镜框2与最前端铰链套41之间、镜腿6与最后端铰链套41可以不直接固定连接。
进一步地，如图13所示，相邻连接板31通过定位销363转动连接。可选地，相邻两个连接板31中，前一连接板31的后端设置前板插孔361，后一连接板31的前端设置后板插孔362，前板插孔361和后板插孔362均套接于定位销363上。具体地，前板插孔361与定位销363固定连接，在套装后两者不能相对转动；后板插孔362与定位销363转动连接，具体为间隙配合，且在后板插孔362中添加阻尼油，以在弯折时体现阻尼性，增加使用手感，最终使得各连接板31连接形成的铰链板组3在可转动的同时具备顺滑的阻尼效果。
进一步地，对于套设有铰链套41的各连接板31，其上至少一个定位销363沿轴向伸出于连接板31并插接于其外铰链套41上，如图13所示，铰链套41与其内连接板31前端的定位销36插接配合，而与该连接板31后端的定位销36在轴向上相分离，可限定铰链套41相对于其内连接板31在前后方向的移动自由度，即图13所示方位下的左右方向。
进一步地，铰链套41的内表面上在轴向上的两端、在佩戴状态下靠近和远离头部的两端分别设置有套限位块，以与连接板31的外表面对应相抵。如图11至图13所示，套限位块包括设置在铰链套41上的第一限位块441、第二限位块442、第三限位块443和第四限位块444。第一限位块441和第二限位块442分别从连接板31的两侧对连接板31进行轴向限位，第三限位块443 和第四限位块444分别从连接板31上在佩戴状态下靠近和远离头部的两侧对连接板31进行限位。更具体地，第二限位块442、第三限位块443和第四限位块444可以对接形成朝向第一限位块441开口的U型槽。通过各套限位块与定位销363的限位，使铰链套41与其内连接板31固定连接为一体运动的结构。
进一步地，如图9和图12所示，铰链套41内的前端设有开口向前的C型槽45，铰链套41能够由后至前套设于对应的连接板31外，直至C型槽45与连接板31前端的定位销363对应扣接，定位销363通过C型槽45连接于铰链套41，其通过C型槽45的设置，便于确定铰链套41在连接板31上套接结束位置的确定。
进一步地，铰链套41上设有沿前后方向贯穿的安装通道，镜腿6的内部空间经各安装通道连通镜框2的内部空间。具体地，第一限位块441与第三限位块443之间在轴向上相间隔设置，该间隔部分构成沿前后贯通的安装通道，以容纳电连接件5等内置于铰链壳4中的部件。其中，在铰链套41中，安装通道可以设置连接板31的空间相连通或者相断开。
进一步地，镜框2和镜腿6之间连接有柔性导热件1，柔性导热件1具体为柔性石墨片、柔性石墨烯等高导热、可多次弯折的材料，能够将发热量较大、温度较高的镜框2侧的热量通过柔性导热件1传至发热较小、温度较低的镜腿6侧，降低镜框2侧的温度，使智能眼镜整体温度较均衡，可提高用户体验。
其中，优选地，柔性导热件1内置于铰链壳4中，具体可由镜腿6穿过各个铰链套41的安装通道伸入镜框2中，使得铰链壳4除了能够遮挡电连接 件5、连接板31外，还能够将柔性导热件1包裹住，可以对柔性导热件1进行保护。更具体地，柔性导热件1的一端固定于镜框2，具体直接固定在镜框2内的发热元器件或热管等导热元器件，柔性导热件1的另一端固定于镜腿6，具体可以固定于镜腿6的内表面上。
进一步地，镜框2、各铰链套41与镜腿6由前至后依次转动连接构成外壳组件，镜框2、左侧的各铰链套41、左侧的镜腿6构成左侧的外壳组件，镜框2、右侧的各铰链套41、右侧的镜腿6构成右侧的外壳组件。
进一步地，在外壳组件中，每相邻两个部件之间分别设有外壳限转结构，以分别限制相邻两个部件可相对转动的角度，由于铰链套41与其内连接板固定连接，外壳限转结构与板件限转结构可以对应设置，使得外壳限转结构配合板件限转结构，在镜腿6相对于镜框2内折(或外翻)转动时，相邻两个连接板31内折(或外翻)到板件限转结构所限定的角度时，外壳组件中对应的相邻两个部件内折(或外翻)到外壳限转结构所限定的角度，进一步提高限转的可靠性。
进一步地，请参考图2、图11和图12所示，在外壳组件的每相邻两个部件中，其中一者上设置连接凸起，另一者上设置连接凹槽，且连接凹槽转动套接于连接凸起外侧。也就是说，镜框2与最前端铰链套41、相邻铰链套41以及最后端铰链套41和镜腿6之间均采用套接连接，可以改善该外壳组件中任意相邻两者的对接处的封闭效果，可以进一步确保对电连接件5的防护效果。
其中，优选地，镜腿6相对于镜框2处于任意可转角度的状态下，外壳组件中相邻两者之间在佩戴状态下靠近头部的一侧和远离头部的一侧均具有 部分面积相重叠，以使各个状态下铰链壳4对其内部部件始终具有较好的遮挡效果，使设备外观美观。
其中，具体地，在外壳组件中，相邻两部件之间，前者的后端设置连接凸起，如图2中镜框2端部的镜框连接凸起22以及图11中各铰链套41后端的套体连接凸起461，而后者的前端设置连接凹槽，如图11中各铰链套41前端的套体连接凹槽462以及镜腿6前端的镜腿连接凹槽。当然，在其他实施例中，如具体实施例二中，如图27所示，在外壳组件中，相邻两部件之间，前者的后端设置连接凹槽，而后者的前端设置连接凸起。
进一步地，连接凹槽的槽口端面中，在佩戴状态下靠近头部的一端构成内折限位面，且远离头部的一端构成外翻限位面，以使连接凸起能够内折运动至与内折限位面相抵以及外翻运动至与外翻限位面相抵。
具体以相邻两个铰链套41之间的限转为例，图15和17所示，后一铰链套41上设有套体内折限位面471和套体外翻限位面472，镜腿6内折转动过程中，后一铰链套41上的套体内折限位面471与前一铰链套41(具体为其上连接凸起的外表面)相抵后，后一铰链套41不能继续内折转动；镜腿6外翻转动过程中，后一铰链套41上的套体外翻限位面472与前一铰链套41(具体为其上与连接凸起前端对接的台阶面)相抵后，后一铰链套41不能继续外翻转动。
进一步地，请参考图15和图17，连接凹槽的内表面、连接凸起的外表面中的至少一者包括圆弧面，且圆心线与连接凹槽和连接凸起两者之间的旋转中心线共线或平行。通过圆弧面的设置，可以提高外壳组件中相邻两个部件转动的顺畅性，避免两者之间发生干涉。
具体地，如图15所示，以连接凹槽和连接凸起两者的旋转中心线S为圆心线，连接凹槽的内表面中在佩戴状态下靠近头部的一侧(即图15中的下侧)、远离头部的一侧(即图15中的上侧)均为以该旋转中心线S为圆心线的圆弧面，其中，各圆弧面的半径与弧长根据与该旋转中心线S的径向距离进行确定，如图15中，连接凹槽的下侧圆弧面距离旋转中心线S距离大于上侧圆弧面距离旋转中心线S的距离更大，下侧圆弧面的半径、弧长也设置成分别大于上侧圆弧面的半径与弧长。
另外，对于连接凸起的外周面，连接凸起的外表面在佩戴状态下远离头部的一侧(即图15中的上侧)为以该旋转中心线S为圆心线的圆弧面。其中，连接凸起上的圆弧面的半径与连接凹槽上对应圆弧面的半径的大小关系可以根据需要进行设置。可选地，连接凸起上侧圆弧面的半径与连接凹槽上侧圆弧面的半径可以设置为相同的或者略小于连接凹槽上侧圆弧面的半径，以使镜腿6外翻转动过程中，连接凹槽上的套体外翻限位面472能够顺利转动至与前侧连接凸起前端对接的台阶面相抵而限转。
此外，对于连接凸起的外周面中靠近头部的一侧(即图15中的下侧)的部分，其优选设置为圆弧面但是其圆心线为平行于旋转中心线S的另一直线，在其他实施例中也可以设置为平面。可选地，如图15所示，连接凸起下侧圆弧面的弯曲程度小于其外连接凹槽下侧圆弧面的弯曲程度，以使镜腿6内折转动过程中，连接凹槽上的套体内折限位面471(具体为其上一边线)能够转动至与前侧连接凸起下侧圆弧面相抵而限转。
当然，在其他实施例中，连接凹槽的内表面、连接凸起的外表面也可以设置为相贴合的球面，能够提高两者之间的密封性。
另外，在其他实施例中，对于镜腿和镜框之间的限转，外壳组件中各部件之间可以不设置外壳限转结构，仅依靠设置在连接板31之间的板件限转结构实现对镜腿6转角的限定，或者，连接板31之间不设置板件限转结构，仅依靠外壳限转结构实现对镜腿6转角的限定。
本申请所提供智能眼镜的具体实施例二中，请参考图21至图32，弹片32、连接板31的结构也可以区别于上述实施例进行设置。可选地，弹片32一体成型于连接板31上。具体地，连接板31具有弹性，具体可根据实际使用所需强度选用适合的不同厚度的不锈钢板材，以在保证连接板31弹性性能较好且强度也满足使用要求。另外，连接板31采用钣金折弯工艺实现，结构设计形状简单、制作简单，成本低效率高，制作精度较高，量产性好。
进一步地，每相邻两个连接板31中，前一个连接板31的后端和后一个连接板31的前端中，一者在轴向上的中部朝向佩戴状态下远离头部的一侧弯折以形成弹片32，而两端朝向佩戴状态下靠近头部的一侧翻转形成第二连接环342，另一者在轴向上的中部朝向佩戴状态下远离头部的一侧翻转形成第一连接环341。第一连接环341与第二连接环342均套接于连接轴343上且所述第一连接环341位于两个所述第二连接环342之间，以实现转动连接。也就是说，连接板31上用于与连接轴343相连接的部分与连接板31是一体结构，通过其卷曲即可实现与连接轴343的连接，能够进一步方便加工，减少设备所需的零部件数量。
具体如图22所示，两个连接板31的对接处，前一个连接板31的后端设置第一连接环341，后一个连接板31的前端设置第二连接环342，前一个连接板31在佩戴状态下远离头部的侧面上形成与弹片32配合挤压的挤压面33， 基于第一连接环341的翻转方向，其相对于挤压面33朝向佩戴状态下远离头部的一侧凸出，可以保证镜腿6处于预设内折极限位置的状态下，弹片32的自由端与挤压面33之间具有足够大的距离，从而确保镜腿6的状态由图26向图25变化的过程中，弹片32的自由端与挤压面33能够保持分离状态，弹片32不会挤压到挤压面33而形变。
其中，优选地，相邻两个连接板31之间，第二连接环342与连接轴343紧配固定，即两者之间固定连接不能相对转动。第一连接环341与连接轴343转动连接，即第一连接环341与连接轴343过盈配合，但可相对转动具备一定的摩擦力，具体可以在第一连接环341内添加阻尼油，由于有摩擦力存在，在弯折时会体现顺滑的阻尼性，增加使用手感，使得各连接板31连接形成的链式结构在可转动的同时具备顺滑的阻尼效果。
其中，优选地，相邻连接板31之间设有板件限转结构，以限制相邻两个连接板31可相对转动的角度。如图24至图26所示，相邻连接板31之间，板件限转结构包括设置在第二连接环342上的限转槽351和设置在弹片32上的弹片限位凸起352，弹片限位凸起352插接于限转槽351中。如图26所示的状态，后一个连接板31相对于连接轴343可内折转动至限转槽351的一端面与弹片限位凸起352相抵，以限定相邻两个连接板31之间可内折转动的最大角度，避免单节连接板31转动角度过大导致镜框2和镜腿6之间电连接件5的各部分弯折角及弯折半径过大。如图24所示的状态，后一个连接板31相对于连接轴343可外翻转动至限转槽351的另一端面与弹片限位凸起352相抵，以限定相邻两个连接板31之间可外翻转动的最大角度，各连接板31的转动具有弯折半径大、可弯折的最大角度小的特征。
此外，外壳组件中，各部件的连接方式以及与连接板的连接方式也不限于按照实施例一的方式进行设置。如图27所示，铰链壳4包括至少两个铰链套41，在相套接的连接凹槽和连接凸起中，连接凹槽的内表面、连接凸起的外表面中一者上设有转轴槽，另一者上固定有转动插接于转轴槽中的转轴柱，以实现铰链套41、镜腿6和镜框2之间的转动连接，且连接的可靠性不受铰链壳4内部结构的影响，如图27所示，套体连接凸起461上在轴向上的两端面上分别设置一个铰链转轴槽42，且两个铰链转轴槽42限定了套体连接凸起461、套体连接凹槽462两者的旋转中心线，套体连接凹槽462上设有与各铰链转轴槽42相配合插接的铰链转轴柱43。
也就是说，该外壳组件中各部件之间通过铰链转轴柱43和铰链转轴槽42的配合实现铰接，而连接板31之间通过连接轴343实现铰接，铰链转轴柱43与连接轴343为不同的部件，外壳组件中各部件的摆动与连接板31连接后形成的铰链板组3的摆动可能并非完全同步。
显然，在其他实施例中，铰链壳4也可以设置为一个铰链套41以套住铰链板组3及电连接件、柔性导热件1等部件，但是，本实施例可通过不同铰链套41的分别转动分担镜腿6和镜框2之间的可外翻角度，能够提高铰链转动的灵活性。另外，铰链套41呈环形，能够套住电连接件5，可以提高对电连接件5的防护效果。
显然，在其他实施例中，外壳组件中，相邻两部件之间还可以通过设置风琴罩实现密封连接，以确保对其内部件的遮挡效果。
当然，在其他实施例中，镜腿6中也可能不设置控制组件，相应地，镜框2和镜腿6之间也不设置电连接件5，所有控制元件均设置在镜框2中。
本说明书中各个实施例采用并列或者递进的方式描述，每个实施例重点说明的都是与其它实施例的不同之处，各个实施例之间相同或相似部分互相参见即可。对于实施例公开的装置而言，由于其与实施例公开的方法相对应，所以描述的比较简单，相关之处可参见方法部分说明。
还需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
