下面结合图1-图12描述根据本申请实施例的一种智能眼镜。
如图1和图2所示，根据本申请一些实施例的智能眼镜，包括：眼镜主体100、镜腿200和天线单元300。
眼镜主体100与镜腿200可转动连接。例如，在眼镜主体100与镜腿200之间设有铰接件或球形连接件，基于铰接件或球形连接件，在用户的手动操作下，可便捷地实现眼镜主体100与镜腿200的转动。
进一步地，天线单元300包括第一天线31与第二天线32，第一天线31设于眼镜主体100上，第二天线32设于镜腿200上，第一天线31或第二天线32用于与智能眼镜上的馈电电路电性连接。其中，本实施例所示的眼镜主体100包括镜框11与镜片12，镜片12安装于镜框11上，镜腿200可转动地安装于镜框11上，从而本实施例可将第一天线31设于镜框11上，第二天线32设于镜腿200上，且沿镜腿200的长度方向延伸。
其中，本实施例的第一天线31既可以设于镜框11内，也可以设于镜框11的表面。本实施例的第二天线32既可以设于镜腿200内，也可以设于镜腿200的表面，对此不作具体限定。
与此同时，馈电电路用于向第一天线31或第二天线32发射射频信号，馈电电路既可以设置于眼镜主体100上，也可以设置于镜腿200上，对此也不作具体限定。
为了便于用户佩戴，本申请实施例的镜腿200通常设有两个，其中一 个镜腿200与镜框11的一端转动连接，另一个镜腿200与镜框11的另一端转动连接。
进一步地，本申请实施例的智能眼镜具有折叠状态和展开状态。在智能眼镜处于折叠状态的情况下，第一天线31与第二天线32分离；在智能眼镜处于展开状态的情况下，第一天线31与第二天线32电性连接。
本申请实施例通过将第一天线31与第二天线32分设于眼镜主体100与镜腿200上，可利用眼镜主体100与镜腿200转动连接的特性，将天线单元300的工作状态与智能眼镜的实际使用场景相匹配。
在智能眼镜的使用场景为用户摘下智能眼镜时，智能眼镜仅作为通信设备使用。在此状态下，用户的头部不对智能眼镜的镜腿200起到支撑作用，智能眼镜处于折叠状态，使得第一天线31与第二天线32彼此分离，天线单元300的有效辐射长度与第一天线31或第二天线32的长度相对应，天线单元300以第一天线31或第二天线32对应的谐振频率工作。
在智能眼镜的使用场景为用户佩戴智能眼镜时，智能眼镜既作为通信设备使用，又作为视力矫正设备使用，从而智能眼镜的使用场景及对应的通信需求发生改变。在此状态下，用户的头部对智能眼镜的镜腿200起到支撑作用，智能眼镜处于展开状态，使得第一天线31与第二天线32相连接，天线单元300的有效辐射长度等于第一天线31与第二天线32的总长度，天线单元300以第一天线31与第二天线32构成的组合天线对应的谐振频率工作。
由此，本申请实施例基于智能眼镜的结构特性实现了对天线单元300的布置，相比于现有的采用电子开关进行天线调谐的方式，本实施例可将天线单元的工作状态与智能眼镜的实际使用场景相匹配，以机械控制的方式便捷地实现对天线单元300的频率调谐，无需在智能眼镜上额外配置电子开关及附属的控制线路，减小了天线单元300对智能眼镜上有限布件区域的占用，实现了智能眼镜的小型化与轻量化设计。
在一些示例中，如图2所示，为了便于基于智能眼镜的状态切换控制 第一天线31与第二天线32电性连接或分离，本实施例所示的眼镜主体100设有连接部13；连接部13与镜腿200转动连接；第一天线31的第一端设于连接部13的第一端，第二天线32的第一端设于镜腿200的第一端。
在智能眼镜处于折叠状态的情况下，连接部13的第一端与镜腿200的第一端远离，以使得第一天线31的第一端与第二天线32的第一端分离。
在智能眼镜处于展开状态的情况下，连接部13的第一端与镜腿200的第一端靠近，以使得第一天线31的第一端与第二天线32的第一端电性连接。
其中，本实施例所示的连接部13的第一端具有第一端面，镜腿200的第一端具有第二端面，可将第一天线31的第一端设于连接部13的第一端面上或部分凸出于连接部13的第一端面，以及将第二天线32的第一端设于镜腿200的第二端面或部分凸出于镜腿200的第二端面。
相应地，在智能眼镜处于折叠状态时，连接部13的第一端面与镜腿200的第二端面相远离，并呈垂直分布，使得第一天线31的第一端与第二天线32的第一端不能保持电连接状态。
在智能眼镜处于展开状态的情况下，连接部13的第一端面与镜腿200的第二端面相靠近，并相贴合或者呈平行分布，使得第一天线31的第一端与第二天线32的第一端能够达到电连接状态。
在一些示例中，如图2所示，为了便于根据智能眼镜的工作状态，便捷地控制第一天线31的第一端与第二天线32的第一端之间的导通状态，本实施例所示的天线单元300还包括导电组件33；导电组件33设于连接部13的第一端与镜腿200的第一端之间。例如，连接部13的第一端与镜腿200的第一端之间设有间隙，导电组件33位于间隙中，连接部13的第一端或镜腿200的第一端与导电组件33电性连接。
在智能眼镜处于折叠状态的情况下，由于连接部13的第一端与镜腿200的第一端远离，使得第一天线31的第一端与第二天线32的第一端断开。此时，第一天线31与第二天线32不处于电性连接状态。
在智能眼镜处于展开状态的情况下，由于连接部13的第一端与镜腿200的第一端靠近，使得第一天线31的第一端与第二天线32的第一端通过导电组件33电性连接。
由此，本申请实施例的导电组件33能够根据智能眼镜的折叠状态与展开状态的切换，便捷地控制第一天线31的第一端与第二天线32的第一端之间的电性连接状态。
显然，本申请实施例的导电组件33的设置不会影响到智能眼镜的正常使用。导电组件33可以为导电柱、导电弹片、机械式切换开关等，在此不做具体限定。
在一些示例中，如图3和图4所示，本申请实施例的天线单元300可配置为monopole天线(单级天线)。天线单元300除了配置上述实施例所示的第一天线31与第二天线32外，还设置有第一地板34。
其中，第一地板34设于眼镜主体100上，并与第一天线31隔离，第一天线31与设于眼镜主体100上的馈电电路电性连接。
或者，第一地板34设于镜腿200上，并与第二天线32隔离，第二天线32与设于镜腿200上的馈电电路电性连接。
在此应指出的是，本申请实施例所示的第一地板34设置的位置是由与monopole天线对应的馈电电路设置的位置确定的。馈电电路在图3和图4中未具体示意出。
例如，在馈电电路设置于眼镜主体100上时，第一地板34设置于眼镜主体100上。此时，第一天线31的第二端与眼镜主体100上的馈电电路电性连接，第一地板34与馈电电路共地。
相应地，在馈电电路设置于镜腿200上时，第一地板34设置于镜腿200上。此时，第二天线32的第二端与镜腿200上的馈电电路电性连接，第一地板34与馈电电路共地。
在一些示例中，为了便于根据智能眼镜的工作状态控制第一天线31的第一端与第二天线32的第一端的电连接状态，本实施例所示的导电组 件33包括弹性导电件331，弹性导电件331包括铜片、铁片或导电泡棉等。
第一天线31的第一端与第二天线32的第一端当中的一者与弹性导电件331电性连接，第一天线31的第一端与第二天线32的第一端当中的另一者与弹性导电件331抵接或分离。
如图2、图3及图4所示，本申请实施例的第一天线31与设置于眼镜主体100上的馈电电路电性连接，第一地板34设置于眼镜主体100上，并与馈电电路共地。本实施例将弹性导电件331设置于镜腿200上，并将第二天线32的第一端与弹性导电件331的一端电性连接。
当用户摘下智能眼镜时，由于用户的头部不对智能眼镜的镜腿200形成支撑，镜腿200可与镜框11平行，即智能眼镜处于折叠状态。此时，位于镜腿200上的弹性导电件331的另一端无法与第一天线31的第一端电性连接，第一天线31与第二天线32呈现为分离状态，天线单元300的有效辐射长度为第一天线31的长度，记为L1，则天线单元300的谐振频率落在f1，假设f1为Wireless Fidelity(WiFi)频段，则在用户摘下智能眼镜的应用场景，用户在室内处于休息状态，在上网时对WiFi的使用频率较高，则用户可正好利用第一天线31提供的频段进行上网。
当用户戴上智能眼镜时，由于用户的头部对智能眼镜的镜腿200形成支撑，镜腿200可被用户的头部支撑至与镜框11垂直，即智能眼镜处于展开状态。此时，第一天线31的第一端与弹性导电件331的另一端抵接，以使得第一天线31的第一端与第二天线32的第一端之间形成电性连接，天线单元300的有效辐射长度为第一天线31与第二天线32的总长度，记为L1+L2，则天线单元300的谐振频率落在f2，明显可得，f2>f1，通过合理设计L2长度，可使f2的谐振频率与全球定位系统(Global Positioning System，GPS)L1(1575.42±1.023MHz)频段或者无线广域网(Wireless Wide Area Networks，WWAN)频段相对应，以方便用户导航或者上网。
此外，本实施例还可配合智能眼镜上其余部分的天线，在用户摘下智能眼镜时，天线单元300在WiFi频段形成MIMO(Multiple-Input  Multiple-Output)多输入多输出，以提高WiFi上下行速率，而在用户戴上智能眼镜后，天线单元300的谐振频率落在GPS与WiFi对应的组合频段，从而实现扩大智能眼镜的通信频段。
基于上述实施例所示的方案，如图3与图4所示，为了确保第一天线31的第一端与弹性导电件331的另一端之间电连接的可靠性，本实施例还可将第一天线31的第一端与第一导电垫片311电性连接，第一导电垫片311设于连接部13的第一端面。其中，第一导电垫片311可以为镀金垫片。
与此同时，为了防止金属结构对天线单元300的工作造成影响，本实施例所示的智能眼镜包括绝缘铰接件400，绝缘铰接件400的一端与连接部13连接，绝缘铰接件400的另一端与镜腿200连接，基于绝缘铰接件400可实现眼镜主体100与镜腿200转动连接。
其中，绝缘铰接件400包括第一铰接部，第二铰接部及铰接钉；第一铰接部的一端与连接部13连接，第一铰接部的另一端与第二铰接部的一端通过铰接钉铰接，第二铰接部的另一端与镜腿200连接。
在一些示例中，如图5至图8所示，本申请实施例的天线单元300可配置为IFA(Inverted-F Antenna)天线。其中，本实施例将天线单元300对应的馈电电路设置于镜腿200上。
为此，本实施例所示的天线单元300还包括第二地板35、第三地板36和第一导电件41。导电组件33包括机械开关333，机械开关333设于镜腿200上。其中，机械开关333可以为单刀双掷开关或双刀双掷开关。
第二地板35设于眼镜主体100上，第三地板36设于镜腿200上，第二地板35和第三地板36通过第一导电件41电性连接。其中，第一导电件41可以为设置于连接部13与镜腿200之间的导电软连接或者导电铰接件，在此不作具体限定，只要是不影响到镜腿200相对于眼镜主体100转动，并实现第二地板35和第三地板36电性连接的导电结构，均满足设计要求。
与此同时，第二地板35的第一端设于连接部13的第一端；第三地板 36的第一端设于镜腿200的第一端；第一天线31的第二端与第二地板35的第二端电性连接，第二天线32与设于镜腿200上的馈电电路电性连接。
在实际布设中，本实施例可将第二地板35沿第一天线31的延伸方向延伸，并与第一天线31间隔设置。与此同时，本实施例可将第二天线32的第二端与镜腿200上的馈电电路电性连接。第三地板36沿第二天线32的延伸方向延伸，并与第二天线32间隔设置，第三地板36的第二端与馈电电路的地端连接。
如图5与图6所示，在智能眼镜处于折叠状态时，由于连接部13的第一端与镜腿200的第一端远离，机械开关333处于初始状态，第二天线32的第一端与第三地板36的第一端通过机械开关333电性连接。此时，天线单元300的有效辐射长度为L2，天线单元300的有效辐射体包括第二天线32、导电组件33及第三地板36，该有效辐射体形成为IFA天线。在此情形下，天线单元300可工作于1/4波长模式下，谐振频率为f0，并具有较高的辐射效率和通信能力。
如图7与图8所示，在智能眼镜处于展开状态时，由于连接部13的第一端与镜腿200的第一端靠近，连接部13的第一端与镜腿200的第一端在靠近的过程中会触发机械开关333，导致机械开关333切换开关状态，使得第一天线31的第一端与第二天线32的第一端通过机械开关333电性连接。此时，天线单元300的有效辐射长度为L1+L2，天线单元300的有效辐射体包括第一天线31、第二天线32、第二地板35、第三地板36及设置于眼镜主体100上的第四地级37，该有效辐射体形成为IFA天线。其中，第一天线31与第二天线32连成一体，第二地板35、第三地板36及第四地级37连成一体。
在实际应用中，通过设计L1的长度大致为L2的长度的两倍，可使得本实施例所示的天线单元300的谐振频率为f0时，工作于3/4波长模式下。此时，天线单元300的效率略低，但是，基于IFA天线工作时在第一天线31与第二天线32上形成的反向电流，使得用户对天线单元300的辐射能 量吸收较低，即比吸收率(Specific Absorption Rate，SAR)降低，减小用户所受的电磁辐射伤害。
在一些示例中，如图6和图8所示，本申请实施例的导电组件33还包括弹性件332。机械开关333包括导电支座3331和导电刀片3332；导电支座3331与第二天线32电性连接，导电刀片3332的中部可转动地设于导电支座3331上，使得导电刀片3332在相对于导电支座3331转动的同时，还能够与导电支座3331电性连接。
与此同时，弹性件332设于导电刀片3332的第一端与镜腿200的第一端之间；弹性件332具有第一状态和第二状态。其中，弹性件332在第二状态的形变量大于弹性件332在第一状态的形变量，弹性件332可以为弹簧。
在智能眼镜处于折叠状态的情况下，第一天线31的第一端与导电刀片3332的第一端分离，使得弹性件332处于第一状态，导电刀片3332的第二端与第三地板36的第一端抵接。
在智能眼镜处于展开状态的情况下，第一天线31的第一端与导电刀片3332的第一端抵接，使得弹性件332处于第二状态，导电刀片3332的第二端在第二地板35与第三地板36之间悬空设置。
在一些示例中，弹性件332所处的第一状态可理解为弹性件332处于自然伸长状态，而弹性件332所处的第二状态可理解为弹性件332处于压缩状态。
如此，在智能眼镜处于折叠状态时，由于连接部13与镜腿200不会对弹性件332施加作用力，弹性件332处于第一状态。在弹性件332的配合下，可确保机械开关333处于初始状态，第二天线32和第三地板36通过机械开关333实现电性连接。
在智能眼镜处于展开状态时，由于连接部13与镜腿200在相靠近的过程中，驱使导电刀片3332的第一端相对于导电支座3331朝向镜腿200的一侧转动，则根据机械开关333的状态切换，第一天线31与第二天线32 通过机械开关333实现电性连接，且导电刀片3332的第二端分别与第二地板35、第三地板36断开。
由于在智能眼镜处于展开状态时，弹性件332由第一状态切换至第二状态，弹性件332存储了一定的弹性势能，则在智能眼镜由展开状态切换至折叠状态时，在弹性件332的驱动下，机械开关333会自动恢复至初始状态。
如图6与图8所示，为了确保导电刀片3332的第一端与第一天线31的第一端电连接的可靠性，本实施例将第一天线31的第一端与第二导电垫片312电性连接。
为了确保导电刀片3332的第二端与第三地板36的第一端电连接的可靠性，本实施例将第三地板36的第一端与第三导电垫片361电性连接，并在第二地板35的第一端设有第一绝缘垫片351。
其中，第二导电垫片312、第三导电垫片361均可以为镀金垫片，第一绝缘垫片351可以为塑料垫片。
基于上述实施例所示的方案，如图9至图12所示，在将天线单元300对应的馈电电路设置于眼镜主体100上的情形下，天线单元300也可配置为另一种形式的IFA天线。
为此，本实施例所示的天线单元300还包括第二地板35、第三地板36和第二导电件42。导电组件33包括机械开关333，机械开关333设于眼镜主体100上。其中，机械开关333可以为单刀双掷开关或双刀双掷开关。
第二地板35设于眼镜主体100上，第三地板36设于镜腿200上，第二地板35和第三地板36通过第二导电件42电性连接。其中，第二导电件42可以为设置于连接部13与镜腿200之间的导电软连接或者导电铰接件，在此不作具体限定，只要是不影响到镜腿200相对于眼镜主体100转动，并实现第二地板35和第三地板36电性连接的导电结构，均满足设计要求。
与此同时，第二地板35的第一端设于连接部13的第一端；第三地板 36的第一端设于镜腿200的第一端；第一天线31与设于眼镜主体100上的馈电电路电性连接；第二天线32的第二端与第三地板36的第二端与电性连接。
在实际布设中，本实施例可将第二地板35沿第一天线31的延伸方向延伸，并与第一天线31间隔设置，第一天线31的第二端与眼镜主体100上的馈电电路电性连接，第二地板35的第二端与馈电电路的地端连接。
与此同时，本实施例可将第三地板36沿第二天线32的延伸方向延伸，并与第二天线32间隔设置。
如图9和图10所示，在智能眼镜处于折叠状态的情况下，由于连接部13的第一端与镜腿200的第一端远离，机械开关333处于初始状态，第一天线31的第一端与第二地板35的第一端通过机械开关333电性连接。此时，天线单元300的有效辐射长度为L1，天线单元300的有效辐射体包括第一天线31、导电组件33、第二地板35及与第二地板35连接的第四地级37，该有效辐射体形成为IFA天线。
如图11和图12所示，在智能眼镜处于展开状态的情况下，由于连接部13的第一端与镜腿200的第一端靠近，连接部13的第一端与镜腿200的第一端在靠近的过程中会触发机械开关333，导致机械开关333切换开关状态，使得第一天线31的第一端与第二天线32的第一端电性连接。此时，天线单元300的有效辐射长度为L1+L2，天线单元300的有效辐射体包括第一天线31、第二天线32、第三地板36、第二地板35及与第二地板35连接的第四地级37，该有效辐射体形成为IFA天线。其中，第一天线31与第二天线32连成一体，第二地板35、第三地板36及第四地级37连成一体。
在一些实施例中，如图10和图12所示，本申请实施例的导电组件33还包括弹性件332。机械开关333包括导电支座3331和导电刀片3332；导电支座3331与第一天线31电性连接，导电刀片3332的中部可转动地设于导电支座3331上，使得导电刀片3332在相对于导电支座3331转动 的同时，还能够与导电支座3331电性连接。
与此同时，弹性件332设于导电刀片3332的第一端与连接部13的第一端之间；弹性件332具有第一状态和第二状态。其中，弹性件332在第二状态的形变量大于弹性件332在第一状态的形变量，弹性件332可以为弹簧。
在智能眼镜处于折叠状态的情况下，第二天线32的第一端与导电刀片3332的第一端分离，使得弹性件332处于第一状态，导电刀片3332的第二端与第二地板35的第一端抵接。
在智能眼镜处于展开状态的情况下，第二天线32的第一端与导电刀片3332的第一端抵接，使得弹性件332处于第二状态，导电刀片3332的第二端在第二地板35与第三地板36之间悬空设置。
如此，在智能眼镜处于折叠状态时，由于连接部13与镜腿200不会对弹性件332施加作用力，弹性件332处于第一状态。在弹性件332的配合下，可确保机械开关333处于初始状态，第一天线31和第二地板35通过机械开关333实现电性连接。
在智能眼镜处于展开状态时，由于连接部13与镜腿200在相靠近的过程中，驱使导电刀片3332的第一端相对于导电支座3331朝向眼镜主体100的一侧转动，则根据机械开关333的状态切换，第一天线31与第二天线32通过机械开关333实现电性连接，且导电刀片3332的第二端分别与第二地板35、第三地板36断开。
由于在智能眼镜处于展开状态时，弹性件332由第一状态切换至第二状态，弹性件332存储了一定的弹性势能，则在智能眼镜由展开状态切换至折叠状态时，在弹性件332的驱动下，机械开关333会自动恢复至初始状态。
如图10与图12所示，为了确保导电刀片3332的第一端与第二天线32的第一端电连接的可靠性，本实施例将第二天线32的第一端与第四导电垫片321电性连接。为了确保导电刀片3332的第一端与第二地板35的 第一端电连接的可靠性，本实施例将第二地板35的第一端与第五导电垫片352电性连接，并在第三地板36的第一端设有第二绝缘垫片362。
其中，第四导电垫片321、第五导电垫片352均为镀金垫片，第二绝缘垫片362为塑料垫片。
由上可知，本实施例在不改变智能眼镜的外观结构的情况下，根据智能眼镜的结构特性适应性地实现对天线单元的布置，减小了天线单元对智能眼镜上有限布件区域的占用，可将天线单元的工作状态与智能眼镜的实际使用场景相匹配，便捷地实现对天线单元的频率调谐，操作简单便捷，可提升用户体验。
