智能穿戴设备 技术领域
本发明涉及无线通信技术领域，特别是涉及一种智能穿戴设备 。
 背景技术
随着科技的进步，无线通讯设备也日渐趋向微型化、轻薄化。不断缩小无线通讯设备的空间使得天线设计面临更大的挑战。
智能穿戴设备为微型无线通讯设备，采取的天线类型主要有单极天线和PIFA天线，但无论何种形式的天线设计，均需要单独设置天线的容置空间并保留对应的净空区，天线的这些需求与智能穿戴设备的微型化之间存在激烈的矛盾，在实际工程案例中，往往是顾此失彼。
 技术问题
因此，如何合理分配设计空间以满足智能穿戴设备的微型化需求，是亟待解决的问题。

 本发明的实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施例。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。
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发明的技术领域的技术人员通常理解的含义相同。本文中在发明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，不是旨在限制本发明。本文所使用的术语“和／或”包括一个或多个相关的所列项目的任意的和所有的组合。
本实施方式提供了一种智能穿戴设备，例如为智能手表、智能手环等。智能穿戴设备在其结构设计时，常常会加入金属元素，而在天线设计时，金属对天线的影响是极大的，并且通常是负面的影响。当智能穿戴设备的结构设计中含有金属时，可以通过本实施方式来消除结构设计中金属对天线的负面影响，同时在不占用更多空间的条件下，得到理想的无线通讯性能。
请参考图1、图3，智能穿戴设备包括金属框10及电路板20。其中，金属框10的材料为金属，形状可以为环状。本实施方式中，仅列出了智能穿戴设备的部分组成结构，根据实际应用情况，智能穿戴设备还可以包括其他部分。例如：请参考图1，当智能穿戴设备为智能手表时，智能穿戴设备还可以进一步包括手表腕带40、手表底壳50、手表按键60、表盘（图1中未示出）等。这些结构件在传统的智能手表中并不具备天线性能。本实施方式采用一种“复用”的思路来设计天线，即通过在金属框10上设置相关的馈点、接地点等来设计天线。具体实现原理如下。
本实施方式中，请参考图1，金属框10上设有第一馈点111、第二馈点112、第一接地点121及第二接地点122。第一馈点111、第二馈点112分别位于由第一接地点121和第二接地点122构成的线段的两侧。
并且，第一馈点111用于馈电以发射和接收第一频段的无线信号。第二馈点112用于馈电以发射和接收第二频段的无线信号。第一接地点121、第二接地点122用于接地。
其中，电路板20上可以设有接地端、射频链路、匹配电路、相关功能芯片（例如蓝牙模块）等。第一接地点121、第二接地点122可以通过一定方式与电路板20上的接地端电连接。第一馈点111可以通过一定方式与电路板20上的匹配电路电连接，并通过匹配电路依次连接射频链路、与第一频段无线信号相关的控制芯片（例如蓝牙模块）。第二馈点112可以通过一定方式与电路板20上的匹配电路电连接，并通过匹配电路依次连接射频链路、与第二频段无线信号相关的控制芯片（例如GPS模块）。
因此，本实施方式中，金属框10可以作为辐射体，在第一馈点111、第一接地点121、第二接地点122的作用下形成能够发射和接收第一频段无线信号的天线（以下称为第一频段天线）。在第二馈点112、第一接地点121、第二接地点122的共同作用下可以形成能够发射和接收第二频段无线信号的天线（以下称为第二频段天线）。此外，由于第一接地点121与第二接地点122的接地作用，使得第一馈点111与第二馈点112的信号相互之间不会产生干扰，即流经第一馈点111的信号不会流入第二馈点112，流经第二馈点112的信号同样不会流入第一馈点111。
综上所述，本实施方式提供的智能穿戴设备有效利用自身具备的金属框10来设计天线，从而可以节约智能穿戴设备的设计空间，易于实现智能穿戴设备的微型化需求。
在其中一个实施例中，金属框10的形状为环状。由于环状的金属框没有拐角，从而可以避免因拐角而损失信号的情况，提高了信号的质量。
具体地，请继续参考图1，第一接地点121与第二接地点122相对圆环状的金属框的中心对称。换言之，第一接地点121与第二接地点122位于金属框的圆环的外圆的一条直径的两端。
具体地，第一馈点111位于由第一接地点121与第二接地点122构成的弧线的中点。因此，位于第一馈点111与第一接地点121之间的辐射体的弧长与位于第一馈点111与第二接地点122之间的辐射体的弧长相等。如此，即可构成两个第一频段天线，即第一馈点111与第一接地点121之间的辐射体作为一个第一频段天线，且天线的类型为环形天线，第一馈点111与第二接地点121之间的辐射体作为另一个第一频段天线，且天线的类型同样为环形天线。这两个第一频段天线的无线信号可以相互叠加，从而进一步提高无线信号的强度。并且，当其中一个第一频段天线出现故障时，另一个第一频段天线仍然可以正常工作，从而可以提高天线的可靠性。
可以理解的是，第一馈点111的位置不限于上述一种情况，例如根据实际需求，如果第一频段频率较低，则可以将第一馈点111向第一接地点121移动，此时第一馈点111与第二接地点122之间的辐射体即可满足第一频段的需求；或者，将第一馈点111向第二接地点122移动，此时第一馈点111与第一接地点121之间的辐射体即可满足第一频段的需求。
具体地，在第一馈点111位于第一接地点121与第二接地点122构成的弧线的中点的前提下，第一馈点111与第二接地点122构成的弧线的长度为蓝牙频段电磁波的四分之一波长。换言之，第一馈点111与第一接地点121之间的金属框10部分为一个蓝牙天线的辐射体，第一馈点111与第二接地点122之间的金属框10部分为另一个蓝牙天线的辐射体。
可以理解的是，第一馈点111、第一接地点121、第二接地点122构成的天线不限于蓝牙天线一种情况，根据实际需求，通过调节第一馈点111、第一接地点121、第二接地点122之间的相对位置，还可以接收和发射其他频段的电磁波，即第一馈点111与第一接地点121之间的辐射体的弧长，和/或第一馈点111与第二接地点122之间的辐射体的弧长设计为其他频段电磁波的1/4至2/5波长，且优选为2/5波长。例如：第一接地点121和第二接地点122同时靠近第一馈点111移动时，天线的谐振频率会向高频方向移动；或者，第一接地点121和第二接地点122同时远离第一馈点111移动时，天线的谐振频率会向低频方向移动。
具体地，第二馈点112与第二接地点122构成的弧线的长度为GPS频段电磁波的1/4至2/5波长。换言之，第二馈点112与第二接地点122之间的金属框10部分为GPS天线的辐射体，即构成了GPS天线，且天线的类型为环形天线。
基于上述设计方案，第二馈点112与第一接地点121之间的金属框10部分可以形成电感效应，从而便于对GPS天线进行阻抗匹配。
可以理解的是，第二馈点112与第一接地点121、第二接地点122构成的天线不限于GPS天线一种情况，根据实际需求，通过调节第二馈点112、第一接地点121、第二接地点122之间的相对位置，还可以接收和发射其他频段的电磁波，即第二馈点112与第一接地点121之间的辐射体的弧长，或第二馈点112与第二接地点122之间的辐射体的弧长，设计为其他频段电磁波的1/4至2/5波长。例如：第二馈点112靠近第一接地点121移动时（注意：第二馈点112不能越过第一接地点121，且与第一接地点121的间距大于0.5mm），天线的谐振频率会向高频方向移动；或者，第二馈点112远离第一接地点121移动时（注意：第二馈点112不能越过第二接地点122，且与第二接地点122的间距大于0.5mm），天线的谐振频率会先向低频方向移动，当第二馈点112移动至第一接地点121与第二接地点122之间的弧线的中点时为最低频率，当第二馈点112越过第一接地点121与第二接地点122之间的弧线的中点时，天线的谐振频率会向高频方向移动。
具体地，当智能穿戴设备为智能手表时，手表底壳50的材质可以为非金属材质或金属材质。当手表底壳50的材质为金属材质时，金属框10与手表底壳50之间的距离大于或等于5mm。
接下来将介绍金属框10上的各触点（即第一馈点111、第二馈点112、第一接地点121、第二接地点122）与电路板20的具体连接方式。
第一种方式为：金属框10上的各接触点与电路板20是直接电连接的。具体原理为：第一接地点121电连接电路板20的接地端，第一馈点111电连接电路板20的第一频段信号处理电路，第二接地点122电连接电路板20的接地端，第二馈点112电连接电路板20的第二频段信号处理电路。
其中，第一频段信号处理电路例如包括匹配电路、射频链路、与第一频段的无线信号相关的控制芯片（如第一频段的无线信号例如为蓝牙信号，则控制芯片为蓝牙模块）。第二频段信号处理电路例如包括匹配电路、射频链路、与第二频段无线信号相关的控制芯片（如第二频段无线信号例如为GPS无线信号，则控制芯片为GPS模块）。
具体地，第一接地点121、第二接地点122、第一馈点111、第二馈点112均可以通过弹片、pogo pin或其他连接方式与电路板20电连接。
进一步地，第一接地点121还可以通过匹配电路电连接电路板20的接地端。第二接地点122还可以通过匹配电路电连接电路板20的接地端。
第二种方式为：在金属框10的形状为环状的前提下，通过“复用”的思路设计可切换式天线，上述实施例中天线复用金属框10的基础上，再次进行天线和天线间的“复用”，即同样是一个金属框10，通过转动的方式来切换不同的馈点、接地点、匹配电路，从而实现不同频段的天线，具体原理如下。
请参考图2，智能穿戴设备还包括材料为绝缘材料的圆环30。圆环30套设于金属框10外或内，并设有第一金属触体310、第二金属触体320、第三金属触体330、第四金属触体340。其中，圆环30可以进行自转。第一金属触体310、第二金属触体320、第三金属触体330、第四金属触体340的材质均可以为金属或其他导电材料。具体地，这些触体可以为钢珠（直径例如为0.5mm至3.0mm），且钢珠可以嵌入圆环30面向金属框10的一端的卡槽内。第一金属触体310、第二金属触体320、第三金属触体330、第四金属触体340用于建立金属框10与电路板20之间的电连接。
电路板20靠近圆环30部分的示意图如图3所示。在电路板20边缘位置分布着不同的接触点，如第一馈点接触点111’、第二馈点接触点112’、第一接地点接触点121’、第二接地点接触点122’。这些接触点可以利用沉金工艺形成。其中，第一馈点接触点111’与电路板20上的第一频段信号处理电路电连接。第二馈点接触点112’与电路板20上的第二频段信号处理电路电连接。第一接地点接触点121’、第二接地点接触点122’分别与电路板20上的接地端电连接。
其中，第一频段信号处理电路例如包括匹配电路、射频链路、与第一频段的无线信号相关的控制芯片（假设第一频段的无线信号为蓝牙信号，则控制芯片为蓝牙模块）。第二频段信号处理电路例如包括匹配电路、射频链路、与第二频段无线信号相关的控制芯片（假设第二频段的无线信号为GPS信号，则控制芯片为GPS模块）。并且，第一金属触体310、第二金属触体320、第三金属触体330、第四金属触体340之间的相对位置与第一接地点121、第一馈点111、第二接地点122、第二馈点112之间的相对位置相同。
本实施例中，当圆环30相对于所述金属框旋转至第一设定位置，如图2所示，第一金属触体310接触第一接地点接触点121’以形成第一接地点121，第二金属触体320接触第一馈点接触点111’以形成第一馈点111，第三金属触体330接触第二接地点触点122’以形成第二接地点122，第四金属触体340接触第二馈点触点112’以形成第二馈点112。
其中，由于第一金属触体310与金属框10始终保持接触状态，因此当第一金属触体310与第一接地点接触点121’接触后，第一频段信号处理电路即可通过第一接地点接触点121’、第一金属触体310建立与辐射体（即金属框10）的电连接，从而相当于形成了第一接地点121。其他金属触体的原理相同，这里就不再赘述。
因此，在本实施例中，金属框10的作用是构成天线辐射体，圆环30的作用是控制上述各金属触体的位置。只要将圆环30进行适当旋转，即旋转至第一设定位置后，通过第一金属触体310、第二金属触体320、第三金属触体330、第四金属触体340即可建立金属框10与电路板20的电连接，从而构成上述第一频段天线和第二频段天线。
进一步地，请继续参考图3，电路板20还设有第三馈点接触点113’、第三接地点接触点123’。这些接触点同样可以利用沉金工艺形成。其中，第三馈点接触点113’与电路板20上的第三频段信号处理电路电连接。第三接地点接触点123’与电路板20上的接地端电连接。第三频段信号处理电路例如包括匹配电路、射频链路、与第三频段无线信号相关的控制芯片。可选地，第三接地点接触点123’也可以通过匹配电路与接地端电连接。
当圆环30相对于所述金属框旋转至第二设定位置时，如图5所示，第一金属触体310接触第三馈点接触点113’以形成第三馈点，第三金属触体330接触第三接地点接触点123’以形成第三接地点。并且，第二金属触体320与第四金属触体340悬空。其中，第三馈点及第三接地点用于发射和接收第三频段的无线信号。第二金属触体320与第四金属触体340悬空，代表此时第二金属触体320与第四金属触体340与电路板20均断开连接。
因此，在本实施例中，只要将圆环30相对于所述金属框旋转至第二设定位置，即可通过第一金属触体310、第三金属触体330建立金属框10与电路板20的电连接，从而构成上述第三频段天线，并且，此时不会构成上述第一频段天线和第二频段天线。
具体地，请继续参考图3，第三馈点接触点113’位于第二馈点接触点112’与第二接地点接触点122’之间。第三接地点接触点123’位于第一接地点接触点121’与第一馈点接触点111’之间。相应地，第三馈点位于第二馈点与第二接地点之间。第三接地点位于第一接地点与第一馈点之间。
具体地，第三频段为云存储功能（NB）对应的频段。换言之，当构成第三频段天线后，该智能穿戴设备即可实现云存储功能，可以与NB基站通讯，实现数据上传功能。进一步地，第三馈点接触点113’与第三接地点接触点123’ 相对于圆环的中心对称。相应地，第三馈点与第三接地点相对于圆环的中点对称。换言之，第三馈点与第三接地点位于圆环外圆的一条直径上的两端。这时，天线将会获得最大效率。
进一步地，请继续参考图3，电路板20上还设有第四馈点接触点114’。该接触点同样可以利用沉金工艺制成。第四馈点接触点114’与电路板20上的第四频段信号处理电路电连接。其中，第四频段信号处理电路例如包括匹配电路、射频链路、与第四频段无线信号相关的控制芯片。
当圆环30相对于所述金属框旋转至第三设定位置时，如图6所示，第一金属触体310接触第四馈点接触点114’以形成第四馈点。并且，第二金属触体320、第三金属触体330、第四金属触体340均悬空。其中，第四馈点用于发射和接收第四频段的无线信号。第二金属触体320、第三金属触体330、第四金属触体340均悬空，代表此时第二金属触体320、第三金属触体330、第四金属触体340均与电路板20断开连接。
因此，当圆环30相对于所述金属框旋转至第三设定位置后，即可通过第一金属触体310建立金属框20与电路板20的电连接，从而形成第四频段天线，且第四频段天线的天线类型为单极子天线。并且，此时不会构成上述第一频段天线、第二频段天线、第三频段天线。
具体地，请参考图3，第四馈点接触点114’位于第一馈点接触点111’与第二接地点接触点122’之间。相应地，第四馈点位于第一馈点与第二接地点之间。
具体地，第四频段为卫星搜救功能（即SOS）对应的频段。因此，当构成第四频段天线后，该智能穿戴设备即可具备卫星搜救功能。
具体地，圆环30的材料可以为陶瓷。此外，圆环30面向金属框10的表面可以按照一定方式（例如抛光）进行光滑处理，以避免在与金属框10反复摩擦时残留金属碎屑，从而提高天线的性能。
可以理解的是，在其他实施例中，也可以设置为环状的金属框10可以旋转，而圆环30不可旋转，并且各金属触体安装于金属框10上。
在另一个可选的实施例中，还可以设置为环状的金属框10和圆环30均是可以旋转的，在使用的过程中，可以任意旋转其中一个来实现不同接触点之间的电连接。也就是说，在上述圆环旋转至某个位置的描述可以理解为，值需要圆环与金属框之间的相对位置满足相应的关系即可。
接下来以图2至图6所示的智能穿戴设备为例，具体介绍能够分别实现日常定位、云存储、卫星搜救功能的智能穿戴设备的具体原理。
如图4所示，在该智能穿戴设备的表盘的三个位置标注了不同功能，本案例中列举了日常定位、云存储、卫星搜救三个功能，并呈三角形分布在表盘上。表盘在天线中的作用是给出不同功能对应的位置，以便于准确控制圆环30旋转的位置。
在该智能穿戴设备中，电路板20上按顺时针方向依次设有第一接地点接触点121'、第三接地点接触点123’、第一馈点接触点111’、第四馈点接触点114’、第二接地点接触点122’、第三馈点接触点113’、第二馈点接触点112’。圆环30上按顺时针方向依次设有第一金属触体310、第二金属触体320、第三金属触体330、第四金属触体340。其中，第一接地点接触点121’、第三接地点接触点123’、第二接地点接触点122’均与电路板20的接地端电连接。第一馈点接触点111’、第四馈点接触点114’、 第三馈点接触点113’、第二馈点接触点112’分别对应于电路板20的第一频段信号处理电路、第四频段信号处理电路、第三频段信号处理电路、第二频段信号处理电路电连接。
当圆环30相对于所述金属框旋转至第一设定位置时，如图2所示，第一金属触体310接触第一接地点接触点121’以形成第一接地点121，第二金属触体320接触第一馈点接触点111’以形成第一馈点111，第三金属触体330接触第二接地点触点122’以形成第二接地点122，第四金属触体340接触第二馈点触点112’以形成第二馈点112，这时即可构成蓝牙天线、GPS天线，该智能穿戴设备即可实现 GPS定位功能和BT蓝牙功能，即日常定位功能，而不具备云存储和卫星搜救功能。
当圆环30相对于所述金属框旋转至第二设定位置（例如从第一设定位置沿逆时针方向旋转120度），如图5所示，第一金属触体310接触第三馈点接触点113’以形成第三馈点，第三金属触体330接触第三接地点接触点123’以形成第三接地点，这时即可构成云存储天线。该智能穿戴设备具有云存储功能，但不具备日常定位和卫星搜救功能。
