本申请提出一种智能穿戴设备天线装置，应用于智能穿戴设备中，该智能穿戴设备可以为智能手表、智能手环等。随着人工智能和穿戴设备的普及，穿戴设备自适应检测方式越来越多，常见的佩戴检测多采用光感应器或感应电容器。光感应器对光路密封和产品组装工艺控制要求较高，同时可能配套光路滤波元件。电容感应器需要根据ID形态进行设计，并且通常需要单独进行感应电容器设计。也即需要在智能穿戴设备中增加较多的元件，然而智能穿戴设备，例如智能手表、手环等正逐步的走入人们的生活作为一种集智能应用和通信交互于一体的小型化智能设备，内部集成了无线通信模块、CPU、电源等模块。由于智能穿戴设备体积限制，较难在智能穿戴设备中增加元件。
为了解决上述问题，参照图1至图8，该智能穿戴设备天线装置包括：
天线底座10；
表带20，与天线底座10电连接，在智能穿戴设备被用户佩戴时，表带20与用户手臂100相切点至与天线底座10的连接点形成的长度为第一长度；
天线本体30，与天线底座10耦合连接；
佩戴姿势检测电路(图未示出)，与天线本体30电连接，用于根据第一长度确定智能穿戴设备被佩戴姿势。
本实施例中，天线底座10可以作为天线装置中的接地部，该天线底座10可以是金属底座，例如可以为纯金属底座，或者至少部分为金属材质制得的金属底座。天线底座10具体可以设置于智能穿戴设备的底壳的一侧，或者与智能穿戴设备的底壳一体成型，也即天线底座10为底壳的部分结构。智能穿戴设备的底壳可以为陶瓷，PC或玻璃等等，本实施例中，智能穿戴设备的底壳可以作为智能穿戴设备的天线本体30与天线底座10中间的介质，从而实现天线本体30与天线底座10的耦合电连接。具体而言，天线底座10可以设置为中空金属环形形状，中间环形区域可以设置为镂空结构，进一步地，在镂空结构中还可以填充设置透明材质的填充件，以供心率传感器等等透过透明填充件对人体的生命体征参数进行检测。底壳在智能穿戴设备佩戴至用户手腕时，贴合用户的手腕，天线底座10能够与用户的手腕接触。天线底座10的厚度、尺寸及形状可以根据实际应用产品及应用环境等进行设置，以满足不同的应用需求。在一具体实施例中天线底座10的形状可以为圆形、方形， 例如为长方形或者正方形。
根据用户的佩戴习惯，智能穿戴设备可以被用户左手佩戴，也可以被用户右手佩戴。可以理解的是，表带20根据其使用的材质进行区分，比如金属表带20、皮革表带20、皮革表带20、硅胶表带20和珠宝表带20等，也可以根据其表带20的收紧方式来区别，比如蝴蝶扣、针扣、卡扣等。本实施例中表带20可以为金属表带20，也可以为至少部分为金属材质制得的金属表带20，例如表带20为非金属如硅胶或皮革表带20来实现时，则可以在表带20内嵌设计侧翼金属，以实现表带20与金属底座之间的电连接。表带20与天线底座10之间可以一体设置，也可以分体设置，当一体设置时，显示组件、天线调节控制器40等可以与表带20及天线底座10可拆卸连接，用户可以根据实际应用需求，更换不同的天线底座10和表带20。
表带20的数量可以为一个，也可以为两个，当设置为一个时，表带20的两个端部固定在表盘的两端。当设置为两个时，两个表带20的一端分别固定在表盘的两端，两个表带20的另一端可以通过卡扣、针扣、蝴蝶扣等可拆卸连接。本实施例以表带20设置有两个为例进行说明，两个表带20分别为第一表带21和第二表带22，第一表带21设置于天线底座10的一端，第二表带22则设置于天线底座10远离第二表带22的另一端。在智能穿戴设备佩戴至用户手腕时，两个表带20与用户手臂100形成有两个相切点，两个相切点分别与天线底座10的连接点形成的长度分别为第一子长度和第二子长度。具体地，第一表带21与用户手腕形成的相切点即为切点A，第二表带22与用户手腕形成的相切点即为切点B。表带20与用户手臂100相切点至与天线底座10的连接点形成的第一长度分别为：切点A距离天线底座10形成的第一子长度L1，以及切点B距离天线底座10形成的第二子长度L2。两个相切点距与天线底座10连接点处的距离不同，也即第一子长度L1与第一子长度L2不同，当然在其他实施例中，也可以设置为相同。并且第一子长度L1和第二子长度L2会随着左右手佩戴的不同而发生变化，例如，在左手切换至右手时，第一子长度L1增大，而第二子长度L2减小，在右手切换至左手时，第一子长度L1减小，而第二子长度L2增大。
佩戴姿势检测电路可以采用微处理器，例如单片机、DSP等等来实现，佩戴姿势检测电路也可以采用智能穿戴设备的MCU来实现，佩戴姿势检测 电路与天线本体30电连接，天线本体30与天线底座10之间耦合连接，随着第一长度的改变，天线本体30与天线底座10耦合产生的电参数(例如电流、电压等)也会随之发生变化，佩戴姿势检测电路可以根据电参数的变化，确定第一长度的具体值。
基于此，本实施例可以在智能穿戴设备中形成第一子长度和第二子长度形成的差分关系与配合实现左右手识别之间建立映射关系，根据第一子长度和第二子长度变化，即可实现在用户佩戴智能穿戴设备时，具体识别出佩戴智能穿戴设备当前被用户左手佩戴还是右手佩戴。
在一些实施例中，还可以根据实际应用的需求，表盘可以适应用户的左右手佩戴不同，表盘的显示组件的显示界面也适应左手/右手进行切换。并且在设置有旋钮70的智能穿戴设备中，旋钮的位置通常是根据左手佩戴来设置的，用户在将智能穿戴设备佩戴至左手时，旋钮70的位置为朝向用户的右手。本实施例还可以根据实际应用的需求将天线检测与内部陀螺仪的数据进行结合，判断出手表当前的佩戴是左手还是右手，并可以结合手势姿势记录统计工作、运动、睡眠等场景为健康分析提供支持。
可以理解的是，智能穿戴设备的表带20与手臂之间形成的切点距离天线底座10的长度不同，天线底座10上的电流就会不同，相应的对应流到天线本体30中的电连接件CN1再到可调电容C1上的电流就不同，可以判断用户的当前手势。对非左撇倾向人而言，左手的活动相较于右手的活动较少，因此在左手佩戴时，左手倾向于朝手腕外侧的表带20长，内侧表带20短。考虑到部分用户为左手书写习惯，在用户佩戴在左手，左手活动较多时，例如在书写时，表带20发生变化，可能会引起误判，上述通过表带20长度变化的例子可以仅适用于手势姿势的判断。为了精确的左右佩戴判断，在一些实施例中，还可以在智能穿戴设备中设置运动传感器等获取用户的运动动作，例如陀螺仪，结合陀螺仪获取的运动数据进一步判断出是左手佩戴还是右手配戴，可以根据运动传感器检测的空间位置数据确定用户手臂的运动轨迹；根据用户手臂的运动轨迹确定智能手表为左手佩戴或右手佩戴。具体而言，在用户为左手佩戴的情况下，佩戴完成后进行抬腕等运动时，会有一个对应的运动数据；在用户为右手佩戴的情况下，佩戴完成后进行抬腕等运动时，会有另一个对应的运动数据；两个运动数据会因为运动轨迹的不同，而产生 不同，因此可以根据用户手臂100相切点至与天线底座10的连接点形成的第一长度的不同，以及运动传感器获取的运动数据的不同，确定用户当前佩戴的是左手还是右手。在一些实施例中，运动传感器作为运动手表，还可以获取用户的运动数据，并且根据用户产生的运动数据，可以产生手势控制指令等，实现控制智能穿戴设备的目的。
本申请通过设置天线底座10及分别与天线底座10电连接的表带20和天线本体30，并且通过天线本体30来根据在智能穿戴设备被用户佩戴时，表带20与用户手臂100相切点至与天线底座10的连接点形成的第一长度，来确定智能穿戴设备被佩戴姿势。本申请利用天线底座10及表带20与天线本体30结合，实现了智能穿戴设备佩戴检测。
参照图1至图8，在一实施例中，天线本体30与表带20及天线底座10构成检测电容；
佩戴姿势检测电路，具体用于根据检测电容的大小，确定智能穿戴设备被佩戴姿势。
本实施例中，天线本体30与天线底座10之间耦合连接，天线本体30与天线底座10，以及与天线底座10电连接的表带20之间形成检测电容，天线本体30相当于检测电容的一个极板，天线底座10与表带20相当于检测电容的另一个极板。表带20与手臂之间的耦合为开放空间的耦合，根据电荷集中分布在金属的边缘位置，即手表表带20内嵌金属与手臂相切位置能引起电荷分布的突变。具体地，当用户手腕分别与天线底座10与表带20接触时，天线底座10与表带20之间的有效长度会发生改变，也即改变了检测电容器中，天线底座10与表带20构成的极板的面积，由静电学可知，对于平行板电容器，有如下的关系式：
C＝εr·S/L      (1)
其中，εr为介电常数，S为天线本体30、天线底座10与表带20形成的检测电容中，两个极板的面积，L为检测电容中两个极板之间的距离，也即天线本体30与天线底座10之间的距离，由公式(1)可知，电容的容量与介质的介电常数成正比，与两个极板的面积成正比，与两个极板之间的距离成反比。
另外，当一个电容器充有Q量的电荷，那么电容器两个极板要形成一定 的电压，有如下关系式：
C＝Q/V        (2)
其中，Q为检测电容所带电荷量，即充电电荷，充电电荷在一个电容器中固定不变，当改变了天线底座10与表带20之间的有效长度，也即改变了电容器两个极板的有效面积，产生了一个ΔS的变化时，由公式(1)可知，必然要产生一个ΔC的变化，由公式(2)进一步得知，由于ΔC的变化，因此会产生一个ΔV的变化。根据电容元件的电压电流关系设电压、电流为时间函数，求其电压、电流关系。当极板间的电压变化时，极板上的电荷也随之变化，于是在电容元件中产生了电流，此电流可由下关系式求得：
I＝dq/dt＝C(dV/dt)   (3)
综上可知，流过检测电容的电流与电容量呈正比例关系，而电容量与两个极板的面积呈正比例关系。基于此，随着表带20与相切点与天线底座10的长度变短，检测电容的电容量则变小，天线底座10流到天线本体30上的电流也就变小。反之，表带20与相切点与天线底座10的长度变长，检测电容的电容量则变大，天线底座10流到天线本体30上的电流也就变大。通过检测检测电容产生的电容量变化变大还是变小，即可实现左右手别，进而在用户佩戴智能穿戴设备时，具体识别出佩戴智能穿戴设备当前被用户左手佩戴还是右手佩戴。
本实施例中，天线本体30与天线底座10构成两个检测电容，分别为第一检测电容和第二检测电容；其中，
佩戴姿势检测电路，具体用于根据第一检测电容和第二检测电容的大小，确定智能穿戴设备被佩戴姿势。
本实施例中，具体而言，可以对应表带20的两个端部，或者对应两个表带20与表盘连接处的位置设置。以两个表带20为例而言，天线本体30经天线底座10与第一表带21及天线底座10构成第一检测电容，第一检测电容可以检测第一表带21与手腕形成的相切点，距离天线底座10的第一子长度的变化。天线本体30经天线底座10与第二表带22及天线底座10构成第一检测电容，第二检测电容可以检测第二表带22与手腕形成的相切点，距离天线底座10的第二子长度的变化。
基于流过检测电容的电流与电容量呈正比例关系，电容量与两个极板的 面积呈正比例关系的特性。若第一表带21与相切点与天线底座10的长度变短，第一检测电容的电容量则变小，天线底座10流到第一机械电子单元上的电流也就变小。此时，而第二表带22与相切点与天线底座10的长度变长，第二检测电容的电容量则变大，天线底座10流到第二机械电子单元上的电流也就变大。通过检测第一检测电容和第二检测电容产生的电容量产生的差分变化，即可实现左右手别，进而在用户佩戴智能穿戴设备时，具体识别出佩戴智能穿戴设备当前被用户左手佩戴还是右手佩戴。同理，在第二表带22与相切点与天线底座10的长度变短，第一表带21与相切点与天线底座10的长度变长，产生相反的变化时，也可以检测识别出佩戴智能在用户左/右手之间的切换。本实施例通过设置两个机械电子单元31、32形成差分的检测电容，可以形成智能穿戴设备的左右手识别自检，可以避免在用户误触发时，导致智能穿戴设备的误判，有利于提高左右手识别的准确性。
参照图7，在一实施例中，天线本体30还包括：
天线调节控制器40，与佩戴姿势检测电路电连接，天线调节控制器40用于根据第一长度确定智能穿戴设备为被佩戴姿势，并根据被佩戴姿势配置两个智能穿戴设备天线装置的天线参数。
需要说明的是，在智能穿戴设备的天线设计时，通常仅针对用户佩戴习惯，例如传统的手表佩戴习惯为左手，智能穿戴设备的天线设计也是针对左手佩戴时进行调试和设置。而在智能穿戴设备佩戴至右手时，天线性能是非对等，此时可能会使得天线性能不是工作在较佳状态而影响智能穿戴设备的正常使用。为此，本实施例针对智能穿戴设备左右手佩戴时天线性能非对称情况下，将可调电容的天线参数设置为可调，从而针对左右手佩戴的不同，适应性的调整天线本体30的天线参数，使天线性能能够跟随左手佩戴或者右手佩戴进行自适应地调节，无需对天线辐射单体进行设计限制，可以提高智能穿戴设备的使用便利性。本申请利用天线底座10和表带20来检测表带20与用户手腕切点距离天线底座10的长度同时实现提高天线辐射效率和佩戴检测，无需另行设置左右手识别用的传感器和电路，即可实现智能穿戴设备天线装置的复用，有利于减少智能穿戴设备的器件使用，可以缩小智能穿戴设备的电控板50体积，使智能穿戴设备更轻便化。
参照图1至图4，在一实施例中，智能穿戴设备天线装置还包括：
机械电子单元31(32)，对应表带的位置，机械电子单元31(32)分别连接天线本体30与天线底座10电连接。
本实施例中，机械电子单元31(32)包括电连接件CN1，电连接件CN1为弹性电连接件CN1。机械电子单元31(32)可以实现天线本体30与天线底座10之间的可拆电连接。机械电子单元的数量为两个；其中，
两个机械电子单元31、32分设于天线底座10沿表带20方向的中心线的两侧；或者，
两个机械电子单元31、32分设于天线底座10沿表带20方向的中心线的同一侧。
本实施例中，两个机械电子单元31、32可以和天线底座10形成两个天线单体，并且两个天线单体可以工作于两个相同的频段，也可以工作于两个不同的频段，例如两个机械电子单元31、32均工作于LTE700频段，此时两个机械电子单元31、32可以使智能穿戴设备具有很好的低频特性。两个机械电子单元31、32也可以分别工作于LTE700频段和LTE1700频段。
两个机械电子单元31、32可以设置对应表带20的位置进行设置，为了缩短与表带20的距离，可以尽可能的靠近表带20的位置进行设置，在两个机械电子单元31、32分设于天线底座10沿表带20方向的中心线的两侧时，其中一个机械电子单元31可以设置在表盘的1点钟位置，另一个机械电子单元32则设置在表盘的7点钟位置。或者，其中一个机械电子单元31可以设置在表盘的11点钟位置，另一个机械电子单元32则设置在表盘的5点钟位置。
在两个机械电子单元31、32分设于天线底座10沿表带20方向的中心线的同一侧时，其中一个机械电子单元31可以设置在表盘的1点钟位置，另一个机械电子单元32则设置在表盘的5点钟位置。或者，其中一个机械电子单元31可以设置在表盘的11点钟位置，另一个机械电子单元32则设置在表盘的7点钟位置。
本实施例中，在智能穿戴设备的表盘上，例如面盖上还可以设置有摄像头60，摄像头60可以设置在表表盘的12点钟方向，两个机械电子单元31、32可以设置在摄像头60的一侧，也即设置在1点钟位置或者11点钟位置， 另一个机械电子单元32则设置在于摄像头60相对远离的一端，例如5点钟位置或者7点钟位置。
参照图7，在一实施例中，智能穿戴设备天线装置还包括：
可调电容C1，可调电容C1的一端与天线调节控制器40连接，可调电容C1的另一端与天线本体连接10连接。
天线调节控制器40具体用于根据被佩戴姿势调节可调电容C1的电容值，以配置智能穿戴设备天线装置的天线参数。
可调电容C1具体可以设置在智能穿戴设备的电控板50上，并且串联在智能穿戴设备的天线网络与天线底座10之间。在实现本实施例的智能穿戴设备的天线性能可调时，可调电容C1的一端可以与智能穿戴设备的天线网络中的天线调节控制器40连接，可调电容C1的另一端可以通过电连接件CN1，例如弹性结构的接触PAD(焊盘)，弹片接触到预留的PAD点等电连接，从而实现与天线底座10电连接。其中，可调电容C1值优选0.5pF～10pF范围。弹性电连接件CN1可以设置为弹片，pogo Pin等，通过电连接件CN1可以实现天线底座10与可调电容C1的可插拔电连接。
如此，在天线装置工作时，电连接件CN1上有耦合电流从天线底座10流到可调电容C1，也即电流自天线底座10经电连接件CN1流向可调电容C1，再经可调电容C1流向智能穿戴设备的天线网络，从而使天线底座10与机械电子单元形成一天线单体，实现无线信号的辐射和接收。本实施例中，天线底座10与表带20一体设计，天线本体30与天线底座10可以从电连接件CN1处可拆卸的连接，可以适用不同的表带20需求或收纳需求。
可调电容C1的电容值可以调节，可调电容C1可以改善天线在高频段的性能。根据可调天线的工作原理是：通过对可调电容C1的容值大小进行微调，天线的阻抗匹配将会由于可调电容C1容值大小可调而产生多种不同的状态，这些不同的阻抗匹配状态组合在一起，在不同场景下，例如左右手佩戴不同的情况下，可以给出其对应的匹配状态，使得该状态下的天线回波损耗和效率最佳，进而使天线无论在何种情况下均能工作在较佳的性能。
可调电容C1的一端还可以与天线本体30的辐射体连接，可调电容C1的另一端经电连接件CN1与天线底座10连接，从而实现辐射体与天线底座10之间的耦合连接，本实施例还可以经可调电容C1实现表带与用户手臂相 切点至与天线底座的连接点形成的长度为第一长度的长度检测，进而实现智能穿戴设备被佩戴姿势。
参照图8，在一实施例中，天线调节控制器40包括：
处理器41，与佩戴姿势检测电路电连接，处理器41用于根据被佩戴姿势输出对应的控制信号；
可调电容驱动芯片，可调电容驱动芯片42的受控端与处理器41连接，可调电容驱动芯片42的输出端与可调电容C1电连接，可调电容驱动芯片42用于根据控制信号调节可调电容C1的电容值，以配置智能穿戴设备天线装置的天线参数。
本实施例中，处理器41可以通过运行或执行存储的软件程序和/或模块，以及调用存储的数据，对接收到的数据、信号进行处理，从而根据接收的电流信号大小来确定此时用户佩戴的左手还是右手，并根据天线与左/右手，以及天线性能之间的映射关系，计算可调电容C1的电容值的调节量，例如可调电容C1的电容区间为最大8.2pF，最小1.2pF，步进0.2pF，在计算出电容值的调节量后，逐步的对可调电容C1的电容值进行调节。处理器41具体可以控制可调电容驱动芯片42工作，通过控制可调电容驱动芯片42的偏置电压，从而对可调电容C1的容值大小进行调节，天线的阻抗匹配将会由于可调电容C1容值变化，工作于其对应的匹配状态，使得该状态下的天线回波损耗和效率最佳。本实施例中还可以通过设置电容配置表的方式，预先根据实际需要进行设置，根据接收的电流信号大小确定此时用户佩戴的左手还是右手，并根据天线与左/右手，以及天线性能之间的映射关系，根据检测的电流信号的大小，从电容配置表中，选择适配的电容值，并对可调电容C1进行调节。
本实施例可以用户佩戴产品后根据两路侧翼金属与手臂之间的检测状态，并将获取的检测的电流信号进行运算比较等信号处理，以根据检测的电流信号大小判断左/右手配戴姿势，并控制可调电容驱动芯片42工作，从而根据电流信号与电容值配置表之间的对应关系，对可调电容C1的电容值大小进行自适应调节。例如，初始状态下两个机械电子单元31、32对应的电容值均为10pF，在用户佩戴智能穿戴设备时，通过处理器41计算电流信号大小，确定检测智能穿戴设备当前的佩戴状态为左手佩戴。当天线装置的工作LTE700频段，根据电容配置表调节一个机械电子单元31对应的可调电容C1 配置8.2pF，另一个机械电子单元32对应的可调电容C1配置为6.8pF时，天线工作在最佳状态。当天线工作在LTE1700频段，根据电容配置表调节一个机械电子单元31对应的可调电容C1配置1.2pF，另一个机械电子单元32对应的可调电容C1配置1.5pF时，天线工作在最佳状态。
参照图1至图4，在一实施例中，天线本体30还包括：
环形金属边框33，环形金属边框33通过两个机械电子单元31、32与天线底座10耦合连接。
本实施例中，环形金属边框33可以是纯金属材料制得，也可以采用金属材料和非金属材料共同构成，环形金属边框33构成智能穿戴设备壳体的一部分，无需占用壳体顶部的空间，可以很好的满足超薄智能穿戴设备的壳体设计需求。环形金属边框33可以采用钛合金、铝等金属材料制得。环形金属边框33的外部轮廓可以呈圆形、方形或多边形。当然在其他实施例中，环形金属边框33的形状可以不限，仅需能适应智能穿戴设备的外形即可。
