技术领域
本申请属于电子设备技术领域，具体涉及一种穿戴设备。
背景技术
随着技术的发展，电子设备的种类也越来越丰富，常见的如手机和平板电脑，还有如智能手表和智能眼镜等穿戴设备。以智能眼镜为例，其通过设置显示模组等结构，可以提供拓展现实的能力。目前的智能眼镜中，缝隙天线通常形成于金属框架上，且缝隙天线延伸至金属框架的边沿，基于此，为了保证金属框架仍能够连为一体，还通常在缝隙天线内填充相应的介质材料，以使金属框架被缝隙天线所分割成的多个部分仍能够重新连为一体，但是，这种金属框架的结构强度仍相对较低，对穿戴设备的结构可靠性存在不利影响。
发明内容
本申请实施例的目的是提供一种穿戴设备，以解决目前的穿戴设备的金属框架中的缝隙天线延伸至金属框架的边沿，导致金属框架的结构可靠性相对较差的问题。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
如图1-图5所示，本申请实施例公开一种穿戴设备，其具体可以为眼镜，穿戴设备包括设备主体100和支撑腿200，且设备主体100的两侧均连接有支撑腿200，以使用户能够利用支撑腿200使穿戴设备与眼睛形成相对稳定的相对固定关系，便于用户使用该穿戴设备。具体地，支撑腿200可以采用可折叠形式，亦可以采用不可折叠形式，且支撑腿200可以采用塑料或金属等材料形成，本文对此均不作限定。
设备主体100为穿戴设备的主体结构，其可以包括金属框架110，当然，设备主体还可以包括射频收发器(图中未示出)等其他器件。金属框架110的外侧可以设有玻璃盖板150，以遮挡设备主体100的内部器件，从而使设备的外观一体化。当然，设备主体100还可以包括电池310、显示模组160和电路板(图中未示出)等器件，可选地，设备主体100还包括如摄像模组170、音频组件320等增强人机交互能力的其他电子器件，且为了减小设备主体100的整体尺寸，且兼顾整个穿戴设备的重心等情况，可以使电池310和音频组件320等器件均安装于支撑腿200的内部。
基于上述包括金属框架110的设备主体100而言，为了使射频收发器能够正常利用金属框架110进行无线信号的收取和发射工作，如图3和图5所述，本申请实施例公开的金属框架110设有第一天线110a和第二天线110b，第一天线110a和第二天线110b均为缝隙天线，且第一天线110a和第二天线110b均与射频收发器连接，从而使第一天线110a和第二天线110b均可以作为用以收发无线信号的器件，即天线而被使用，换句话说，第一天线110a和第二天线110b作为slot天线。另外，该第一天线110a和第二天线110b具体可以为无线网络天线，也即Wi-Fi天线，从而使穿戴设备能够利用第一天线110a和第二天线110b进行无线网络通信。
同时，为了扩大本申请实施例公开的穿戴设备对于无线信号的频段的覆盖范围，在本申请实施例中，可以对第一天线110a和第二天线110b的狭缝长度进行设计，使第一天线110a在作为天线时，可以用以接收和/或发射第一频段的无线信号，且使第二天线110b在作为天线时，可以用以接收和/或发射第二频段的无线信号，且第二频段大于第一频段。
需要说明的是，第一频段和第二频段并非一定仅为一特定数值的频率，二者具体均可以为两个频率值之间的频率的集合，且第二频段所包括的频率均大于第一频段所包括的频率。例如，第一频段具体可以为2.4GHz所包括的多个频率，相应地，第二频段具体可以为5GHz所包括的多个频率，在这种情况下，可以提升穿戴设备的无线通信性能。当然，在相应的需求下，亦可以使第一频段和第二频段采用其他频率，本文对此不作限定。
如上所述，在实际应用中，可以通过对第一天线110a和第二天线110b的缝隙尺寸进行设计，使二者分别具备接收和/或发射相应频率的无线信号；在本申请的其他实施例中，还可以对第一天线110a和第二天线110b的对应结构进行设计，以使二者在某些特定条件下依次分别具备接收和/或发射第一频段和第二频段的无线信号，而在二者的结构所对应的条件发生变化的情况下，则使得第一天线110a和第二天线110b可能还分别具备接收其他频段的无线信号的能力，对此，下文再进行详细介绍。也即，在本申请中，第一天线110a用以接收和/或发射第一频段的无线信号仅是对其所具备的能力的介绍，而非对其所能够接收的无线信号的频率的限制，相似地，对第二天线110b的描述亦是如此。
在本申请实施例公开的穿戴设备的设计过程中，可以根据所需的天线频段的具体参数，适应性地对第一天线110a和第二天线110b的缝隙长度进行设计，且使二者在对应的位置延伸。可选地，第一天线110a和第二天线110b中的至少一者可以自金属框架110的中间位置处延伸至金属框架110的边沿位置处，从而在加工第一天线110a和第二天线110b的过程中，降低二者的加工难度，且在一定程度上提升天线性能。
为了提升金属框架110的整体结构强度和可靠性，在本申请的另一实施例中，可以使第一天线110a和第二天线110b各自的边沿均与金属框架110的边沿间隔设置。例如，金属框架110为一整块金属板材，则可以使第一天线110a和第二天线110b均位于金属框架110的外边沿的内侧，也即，第一天线110a和第二天线110b均为封闭的天线结构，二者均未延伸且连通至金属框架110的外沿。当然，在金属框架110设有内孔等结构时，前述内孔的边沿亦属于金属框架110的边沿的一部分，相应地，第一天线110a和第二天线110b亦均与前述内孔的边沿间隔设置，使第一天线110a和第二天线110b均不与内孔的边沿连通。在采用这种技术方案的情况下，还可以提升整个穿戴设备的外观体验。
本申请实施例公开一种穿戴设备，其设备主体100的相对两侧设有支撑腿200，以便于用户穿戴该设备，且设备主体100包括金属框架110，从而可以提升设备主体100的整体结构强度，且可以大幅提升设备主体100的散热性能，进而还可提升穿戴设备的无线信号的收发性能。同时，金属框架110上设有第一天线110a和第二天线110b，二者均为缝隙天线，从而使第一天线110a和第二天线110b可以作为穿戴设备中的天线，进行信号的接收和/或发射工作。其中，第一天线110a用以接收和/或发射第一频段的无线信号，第二天线110b用以接收和/或发射第二频段的无线信号，第二频段大于第一频段，使得穿戴设备对于无线信号的频段兼容能力相对较好，从而可以提升穿戴设备的用户体验。并且，在本申请实施例公开的穿戴设备中，第一天线110a和第二天线110b各自的边沿均与金属框架110的边沿间隔设置，也即，第一天线110a和第二天线110b均整体上位于金属框架110的外沿之内，从而使设有多频段的天线的金属框架110的外沿仍为完整的闭合环状结构，使金属框架110的结构稳定性相对较高，进而提升整个穿戴设备的使用寿命。
如上所述，第一天线110a和第二天线110b均设置于金属框架110，为此，可以在金属框架110的中部设置第一天线110a和第二天线110b，或者，如上所述，穿戴设备具体可以为眼镜，在此情况下，为了使穿戴设备与用户的脸部具有较强的适应性，穿戴设备中的设备主体100以及其所包括的金属框架110的中部，通常均设有用以避让用户的鼻梁的区域，从而大体上将金属框架110划分为与用户的左眼和右眼分别对应的部分。为此，可以使第一天线110a和第二天线110b中的一者设置于金属框架110中与用户的左眼对应的部分上，且使另一者设置于金属框架110中与用户的右眼对应的部分上。
为了尽量降低用户的头部对穿戴设备的天线性能的不利影响，在本申请的再一实施例中，可选地，如图3和图5所示，第一天线110a和第二天线110b中的至少一者位于金属框架110靠近支撑腿200的边沿区域，在这种情况下，当穿戴设备被用户所使用时，第一天线110a和第二天线110b中设置于边沿区域中一者或两者与用户的脸颊和鼻梁的距离均相对较小，从而可以提升天线的辐射效率。
需要说明的是，相对于金属框架110中靠近金属框架110用以避让用户的鼻梁的区域的部分与支撑腿200的距离而言，金属框架110中靠近支撑腿200的部分与支撑腿200的距离相对更小，其中，金属框架110中靠近支撑腿200的部分即为上述边沿区域。但是，设置于金属框架110中靠近支撑腿200的边沿区域的第一天线110a和第二天线110b与金属框架110的最外沿之间仍有大于零的间距，或者说，第一天线110a和第二天线110b均为设置于金属框架110中的封闭式孔状或槽状结构，也即，第一天线110a和第二天线110b各自的边沿均仍能够与金属框架110的边沿呈间隔设置的状态。而对于第一天线110a和/或第二天线110b与金属框架110靠近支撑腿200的一侧的最外沿的间距的具体值，则可以根据实际需求灵活确定，本文对此不作限定。
具体地，可以使第一天线110a和第二天线110b中的一者沿金属框架110的左侧或右侧边沿延伸，且使另一者沿金属框架110中的上侧或下侧边沿延伸，从而保证二者的天线辐射效率均相对较高。另外，在本申请实施例中，可以使第一天线110a和第二天线110b均设置于金属框架110中用以与用户的左眼(或右眼)对应的部分上，或者，亦可以使第一天线110a和第二天线110b中的一者设置于金属框架110中用于与用户的左眼对应的部分上，且使另一者设置于金属框架110中用于与用户的右眼对应的部分上。
考虑到穿戴设备在被使用的过程中，可能受用户的状态等因素所影响，导致用户的头部遮挡于第一天线110a和/或第二天线110b与路由器等无线信号收发设备之间，造成天线的辐射效率减弱的情况，在本申请的另一实施例中，可选地，如图4所示，本申请实施例公开的穿戴设备中，金属框架110中分别靠近两个支撑腿200的边沿区域中的一者设有第一槽体111，另一者设有第二槽体112，也即，金属框架110靠近一个支撑腿200的边沿区域设有第一槽体111，且金属框架110靠近另一支撑腿200的边沿区域设有第二槽体112，这使得第一槽体111和第二槽体112所包括的缝隙天线均基本不会被用户的脸颊和鼻梁所遮挡，以提升各天线的辐射性能；同时，通过使第一槽体111和第二槽体112均包括第一狭缝113和第二狭缝114，且通过使各第一狭缝113均可用于接收和/或发射第一频段的无线信号，使各第二狭缝114均可用于接收和/或发射第二频段的无线信号，即可使第一槽体111和第二槽体112均单独具备接收第一频段和第二频段的无线信号的能力，进而在设备的使用过程中，可以保证第一槽体111和第二槽体112中的至少一者不会被用户的头部正面遮挡，从而提升穿戴设备的天线性能的鲁棒性。
更进一步地，在设计第一槽体111和第二槽体112的过程中，可以使第一槽体111和第二槽体112对称设置，这可以降低第一槽体111和第二槽体112的加工难度。当然，在本申请的其他实施例中，亦可以使第一槽体111和第二槽体112呈非对称设置。另外，对于第一槽体111和第二槽体112中分别用以接收第一频段的第一天线110a而言，可以使二者的极化方向相同，如均为水平极化或竖直极化；相似地，对于第一槽体111和第二槽体112中分别用以接收第二频段的第二天线110b而言，亦可以使二者的极化方向相同，如均为水平极化或均为竖直极化。
而在另一实施例中，可以使第一槽体111和第二槽体112各自的第一天线110a的极化方向相互垂直，且使第一槽体111和第二槽体112各自的第二天线110b的极化方向相互垂直，在这种情况下，可以使各第一天线110a和各第二天线110b之间的隔离度和包络相关系数均相对较好，进而可以提升多输入多输出(multiple input multiple output，MIMO)天线的性能。
而在上述包括第一槽体111和第二槽体112的金属框架110中，为了进一步提升均用以接收第一频段的无线信号两个第一天线110a之间的隔离度，且提升均用以接收第二频段的无线信号的两个第二天线110b之间的隔离度，在本申请的一个具体实施例中，可以使第一槽体111的第一天线110a的极化方向垂直于第二槽体112的第一天线110a的极化方向，且使第一槽体111的第二天线110b的极化方向垂直于第二槽体112的第二天线110b的极化方向。也即，使第一槽体111和第二槽体112中分别用以接收和/或发射第一频段的天线(即第一狭缝113)的极化方向正交设置，且使第一槽体111和第二槽体112中分别用以接收和/或发射第二频段的天线(即第二狭缝114)的极化方向亦正交设置，从而进一步提升MIMO天线的性能。
基于上述实施例，可选地，第一槽体111和第二槽体112的结构可以呈非对称设置。例如，可以使第一槽体111中用以作为第一天线110a的第一狭缝的极化方向为垂直极化方向，且使其用以作为第二天线110b的第二狭缝的极化方向为水平极化方向；对应地，使第二槽体112中用以作为第一天线110a的第一狭缝的极化方向为水平极化方向，且使第二槽体112中用以作为第二天线110b的第二狭缝的极化方向为垂直极化方向，从而保证两个第一天线110a的极化方向相互垂直，且使两个第二天线110b的极化方向相互垂直。
具体来说，在布设第一槽体111和第二槽体112的过程中，可以使第一槽体111中的第一狭缝113的延伸方向与第二槽体112中的第一狭缝113的延伸方向垂直或大体上呈相互垂直的状态；相应地，使第一槽体111中的第二狭缝114的延伸方向与第二槽体112中的第二狭缝114的延伸方向垂直或大体上呈相互垂直的状态。
为了使第一槽体111的第一天线110a的极化方向垂直于第二槽体112的第一天线110a的极化方向，且使第一槽体111的第二天线110b的极化方向垂直于第二槽体112的第二天线110b的极化方向，在本申请的另一实施例中，还可以对穿戴设备的结构，具体为第一狭缝113和第二狭缝114的结构或配合器件进行设计，通过增加第一狭缝113和第二狭缝114所能够接收的无线信号的频段的范围，且利用不同的控制条件，使第一狭缝113和第二狭缝114各自均具备单独接收和/或发射第一频段和第二频段的能力。
详细地说，可以使第一狭缝113和第二狭缝114在金属框架110上所延伸的长度均相对较大，以使二者均具备覆盖第一频段的无线信号的能力。在此情况下，可以在各第一狭缝113和各第二狭缝114各自两端之间的某一对应位置分别设置如开关等可控式通断器件，以在开关处于闭合的状态下，利用开关作为导通件，减小第一狭缝113和第二狭缝114各自作为缝隙天线的部分的有效长度，使第一狭缝113和第二狭缝114各自的馈电处与开关之间所夹持的部分的长度满足接收和/或发射第二频段的无线信号的条件；而在开关处于断开的状态下，使得第一狭缝113和第二狭缝114的相背两侧无法导通，从而使第一狭缝113和第二狭缝114各自的馈电处至各自的末端之间的部分的长度满足接收和/或发射第一频段的无线信号的条件。在此情况下，可以通过控制各开关的通断状态，使第一槽体111和第二槽体112各自的第一狭缝113和第二狭缝114能够在不同的条件下分别用以接收和/或发射第一频段和第二频段的无线信号。当然，对于上述开关的具体位置，可以根据各第一狭缝113和各第二狭缝114各自的具体长度和馈电点的位置，以及是否填充有其他介质材料等参数灵活确定，对此，在下文中再详细介绍。
更详细的说，本申请实施例公开的穿戴设备中，设备主体100还包括第一开关121和第二开关122，且各第一狭缝113均设置有第一开关121，且各第二狭缝114均设置有第二开关122，从而通过控制各第一开关121和第二开关122的通断情况的方式，对应地控制第一狭缝113和第二狭缝114所能够接收和/或发射的无线信号的频段。
详细地说，在第一开关121断开的情况下，使得第一狭缝113的长度相对较长，能够用以接收和/或发射第一频段的无线信号，而在第一开关121闭合的情况下，使得第一狭缝113的一部分在第一开关121的导通作用下而与第一狭缝113的另一部分断开，使得第一狭缝113中位于馈电点和第一开关121之间的部分能够用以接收和/或发射第二频段的无线信号；相对应地，在第二开关122断开的情况下，第二狭缝114可以用以接收和/或发射第一频段的无线信号，且在第二开关122闭合的情况下，使得第二狭缝114能够用以接收和/或发射第二频段的无线信号。在此情况下，使得第一狭缝113和第二狭缝114均可以单独作为第一天线110a和第二天线110b。
基于上述实施例，在金属框架110包括第一槽体111和第二槽体112，且在第一槽体111和第二槽体112均包括第一狭缝113和第二狭缝114的情况下，可以通过采用上述技术方案，使各第一狭缝113和各第二狭缝114均配设第一开关121和第二开关122，从而通过改变第一开关121和第二开关122的状态，使第一槽体111和第二槽体112中各自用以接收和/或发射第一频段的部分的极化方向相互垂直，且使二者中各自用以接收和/或发射第二频段的部分的极化方向亦相互垂直。
并且，在上述采用上述实施例公开的技术方案的情况下，可以通过改变第一槽体111和第二槽体112各自中所设置的第一开关121和第二开关122的状态等方式，改变第一槽体111和第二槽体112中用以发射和接收第一频段(和第二频段)的部分的所在位置，进而使穿戴设备根据相应频段的信号强弱，对应地切换分别用以接收和/或发射第一频段和第二频段的部分所在的位置，提升穿戴设备的天线性能。
为了降低穿戴设备中第一槽体111和第二槽体112的加工难度，可选地，在第一槽体111和第二槽体112上均设有第一开关121和第二开关122的情况下，可以使第一槽体111和第二槽体112的结构对称设置。并且，在此情况下，为了提升各第一天线110a和各第二天线110b的性能，在第一槽体111的第一开关121闭合的情况下，可以使第一槽体111的第二开关122断开、第二槽体112的第一开关121断开、第二槽体112的所述第二开关闭合。并且，在第一槽体111的第一开关121断开的情况下，使第一槽体111的第二开关122闭合、第二槽体112的第一开关121闭合、第二槽体112的第二开关断开。在此情况下，可以保证第一槽体111中被用作第一天线110a的部分的极化方向能够与第二槽体112中被用作第一天线110a的部分的极化方向相互垂直，且保证第二槽体112中被用作第二天线110b的部分的极化方向能够与第二槽体112中被用作第二天线110b的部分的极化方向相互垂直。
如上所述，可以在金属框架110上设置第一槽体111和第二槽体112，且使二者均包括第一狭缝113和第二狭缝114，同时，可以使第一狭缝113和第二狭缝114作为天线，且用以接收无线网络信号，也即，第一狭缝113和第二狭缝114均为无线网络天线。基于此，为了扩大穿戴设备与其他设备之间的连接能力，提升穿戴设备的可拓展性，可选地，如图4所示，穿戴设备还包括外接设备连接天线130，且通过使该外接设备连接天线130与射频收发器连接，以利用外接设备连接天线130接收和/或发射第三频段的无线信号，使得穿戴设备能够利用该外接设备连接天线130与穿戴设备之外的其他设备连接，以实现穿戴设备与外部设备相互连接的目的，外部设备具体可以为手柄等外设产品。另外，外接设备连接天线130具体可以为PIFA天线，也即，倒F结构形式的天线，其所采用的无线连接形式具体可以为蓝牙连接协议。当然，其亦可以采用其他结构形式以及其他无线连接的方式，本文对此不作限定。
在布设外接设备连接天线130的过程中，可以根据设备主体100中具体的器件布局情况，灵活地设置外接设备连接天线130的具体位置。在本申请的另一实施例中，为了使第一槽体111和第二槽体112所代表的天线与外接设备连接天线130之间的隔离度均相对较好，如图4所示，可以使外接设备连接天线130设置于第一槽体111和第二槽体112之间。并且，在第一槽体111和第二槽体112对称设置的情况下，通过使外接设备连接天线130与第一槽体111和第二槽体112之间的相对位置相同或基本相同，可以进一步提升第一槽体111和外接设备连接天线130之间，以及第二槽体112和外接设备连接天线130之间的隔离度，从而进一步提升穿戴设备中各天线的整体性能。
如上所述，金属框架110上可以设置有第一槽体111和第二槽体112，为了在一定程度上减小整个穿戴设备的重量，可选地，如图5所示，且结合图4，金属框架110还可以设有减重孔110c，且减重孔110c位于第一槽体111和第二槽体112之间，从而在尽量降低对金属框架110的结构强度的影响的情况下，大幅降低金属框架110的重量，进而达到使穿戴设备减重的目的，提升穿戴设备的用户体验。另外，在设有上述减重孔110c的情况下，还可以进一步阻断第一槽体111和第二槽体112之间的耦合路径，进一步改善二者之间的隔离度。
如上所述，金属框架110上设有第一槽体111和第二槽体112，可选地，在穿戴设备的加工过程中，还可以在各第一槽体111和第二槽体112中填充介质材料，以提升金属框架110的整体性，进而保证金属框架110具有良好的结构可靠性。
在此情况下，基于所填充的介质材料的介电常数，以及第一频段和第二频段各自的具体范围等参数，可以确定第一天线110a和第二天线110b的长度。在金属框架110上设有包括第一狭缝113和第二狭缝114的第一槽体111和第二槽体112的情况下，亦可以根据所填充的介质材料对应地确定第一狭缝113和第二狭缝114的长度，以及各第一狭缝113和各第二狭缝114上所分别设置的第一开关121和第二开关122的具体位置，保证第一狭缝113和第二狭缝114在对应的条件下均具备接发第一频段和第二频段的无线信号的能力。例如，第一狭缝113和第二狭缝114中可以填充有玻璃材料，在此情况下，为了保证第一天线110a能够覆盖2.4GHz的无线信号，且可以使第一狭缝113和第二狭缝114的长度均在35-40mm左右，且在第一狭缝113和第二狭缝114各自与馈电点之间的间距为8-10mm左右的位置分别设置上述第一开关121和第二开关122，从而在第一开关121和第二开关122处于闭合的状态下，使第一狭缝113和第二狭缝114作为第二天线110b，能够覆盖5GHz的无线信号。另外，第一槽体111和第二槽体112的宽度可以在1mm～2mm之间。
可选地，第一天线110a和第二天线110b为分段式结构，且二者可以采用分别馈电的方式与射频收发器连接，在本申请的另一实施例中，可以使第一天线110a的一端和第二天线110b的一端连通，且使设备主体100还包括馈电连接部140，进而使馈电连接部140连接于第一天线110a和第二天线110b的连接处，使得第一天线110a和第二天线110b可以同时被馈电，进而减少穿戴设备中所需设置的器件的数量，且降低穿戴设备的组装难度。
另外，如上所述，可以使金属框架110包括第一槽体111和第二槽体112，且在第一槽体111和第二槽体112各自的第一狭缝113和第二狭缝114上分别设置第一开关121和第二开关122。基于此，通过使第一狭缝113和第二狭缝114的长度均能够覆盖上述第一频段的无线信号，且使第一槽体111和第二槽体112各自的第一狭缝113和第二狭缝114相互连通，二者的连接处可以设置有馈电连接部。在采用上述技术方案的情况下，若第一狭缝113和第二狭缝114的填充介质仍为玻璃，在对该天线的S参数和仿真效率进行仿真的过程中，第一狭缝113和第二狭缝114还可以被应用于7GHz的相关频段，从而使该天线能够覆盖2.4GHz，5.1GHz，5.8GHz，6GHz(5.925～7.125GHz)等频段，从而满足Wi-Fi6E和Wi-Fi7的频段需求，进一步扩大穿戴设备所支持的频段范围，提升其数据传输的稳定性和可靠性，且降低延迟。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
