具体实施方式
下面将结合附图，对本申请的具体实施方式进行清楚地描述。
如图1、图2和图3所示，一种具体的实施方式中，本申请提供的智能穿戴产品为智能手表，智能穿戴产品100包括外壳10，外壳10内部形成包围空间，用于容纳智能穿戴产品100的电路板20、功能器件22等电子器件和机械结构。外壳10包括共同形成包围空间的表盘11、中框12和底壳13。智能穿戴产品100佩戴于人体时，表盘11用于提供操作界面及可视窗口以供使用者观看，底壳13用于与人体手腕接触，底壳13上设透明部131。
智能穿戴产品100内的电路板20上设功能器件22和供电电路21，功能器件用于采集人体参数，具体而言，功能器件22为心率检测装置，功能器件22的光线穿过透明部131采集人体信息。
本申请提供的智能穿戴产品还包括电致变色膜40，所述电致变色膜40设置于所述外 壳10的内表面(具体为底壳13的内表面)且遮挡所述透明部131。所述供电电路21用于为所述电致变色膜40和所述功能器件22供电，具体而言，供电电路21可以为电路板20上的处理器，供电电路21与功能器件22通过电路板内部走线或FPC电连接。所述电致变色膜40用于在所述功能器件22工作时呈透明状，且在所述智能穿戴产品100未佩戴于人体时与所述外壳10共同呈现一体化目视效果，一体化目视效果指的是颜色一致，或者颜色不同，但色调搭配上具有一体化的效果，呈现出的视觉效果为电致变色膜40与外壳10混为一体，看不出透明部131的存在。
具体而言，电致变色膜40位于底壳13的内表面。参阅图3，底壳13包括主体132和透明盖板134。主体132设通孔1321，透明盖板134连接至主体132且遮挡所述通孔1321，以形成所述透明部131，即透明部131处，通过透明盖板134作为底壳13的一部分来遮挡智能穿戴产品的内部器件。透明盖板134与所述主体132可以集成为一体式结构，例如，通过采用双色成型工艺集成形成一体式结构。图3所示的实施方式中，透明盖板134为单独零件，通过粘贴固定连接至主体132的通孔1321处，透明盖板134部分收容在通孔1321内部，且透明盖板134的处表面与主体132的外表面共面，可以共同构成平面也可以共同构成弧面。主体132部分的材料和透明盖板134材料可以不同，例如，主体为金属材质，透明盖板为塑料材质。
如图4所示，底壳132包括凸台1324和围绕凸台1324的外围区域1323。凸台1324自底壳132的外表面的中心区域外凸设置。凸台1324用于接触人体，所述凸台1324的材质呈透明状，所述透明部131形成在所述凸台1324上。具体而言，通过在所述凸台1324的内表面设遮光层136形成透明部131，所述遮光层136包围的区域形成所述透明部131。镀膜层15遮盖所述凸台1324的外表面。通过在凸台1324的内表面设置遮光层136，遮光层136为遮光状态，遮光层136设有通孔，通孔的位置的凸台1324未被遮光层136遮挡，这个区域即形成透明部131。具体而言，凸台1324上设有四个透明部131，均呈圆形，遮光层136为油墨，油墨的颜色与底壳13外表面上非透明区域部分(可以理解为外围区域1323)共同呈现一体化目视效果。透明部131的形状也可以为方形、三角形，不规则形状等等，由于电致变色膜40的作用，智能穿戴产品100未佩戴时，透明部131是不可见的，因此不需要将透明部131的参数(形状尺寸)设计得很精细，只要有透光作用就好，因此，电致变色膜40的存在，可以减少底壳13上透明部131处的制作成本。
如图2和图3所示，透明部131的数量为四个，两排两列排列设置。如图5所示，功能器件22包括两个光电二极管221和两个发光件222，发光件222具体为LED灯，其中两个透明部131分别与两个光电二极管221相对设置，另两个透明部131分别与两个发光件222相对设置。发光件222的光线穿过透明部131，且通过光电二极管221采集人体的心率。
如图3和图4所示，底壳13的外表面设有镀膜层15，镀膜层15与底壳132结合，能加强智能穿戴产品100的外观一体化效果。
电致变色膜40可以为独立于外壳10的元件，电致变色膜40贴合至底壳内表面。电致变色膜40也可以与底壳13集成为一体。
一种可能的实施方式中，所述电致变色膜40贴合至所述透明盖板134的内表面， 所述透明盖板134的外表面与所述主体132的外表面共同构成一体化的外表面。本实施方式中，电致变色膜40与透明盖板134互为独立的结构，电致变色膜40可以通过胶水粘贴在透明盖板134的内表面，本实施方式，不需要改变现有的智能穿戴产品100的外壳的结构，只需要在现有的外壳的架构上，直接粘贴电致变色膜40，将电致变色膜40电连接至智能穿戴产品内的电路板上，制作成本低。
另一种可能的实施方式中，所述电致变色膜40与所述透明盖板134集成为一体式结构。电致变色膜40与透明盖板134集成为一体，方便安装，省去了电致变色膜40与透明盖板134之间的组装工艺。
电致变色膜40与透明盖板134集成为一体的具体架构可以为：所述电致变色膜40位于所述透明盖板134的外表，即透明盖板134与电致变色膜40层叠设置，且组装在外壳10的主体132上时，透明盖板134遮挡在电致变色膜40的外表面。另一种实施方式中，所述电致变色膜40内嵌在所述透明盖板134的内部，即将电致变色膜40通过一体成型技术形成透明盖板134的中间夹层，电致变色膜40的两侧均有透明材质保护，有利于增加电致变色膜40的使用寿命，且可以使得整体尺寸更薄，可以理解，透明盖板134的透明材料同时作用电致变色膜40的保护层，电致变色膜40就不再需要其本身的保护层结构了。
如图3和图5所示，电路板20作为智能穿戴产品的主板，承载了大部分的内部器件，电路板20层叠设置在底壳13和表盘11之间，电路板20朝向底壳13的表面设置功能器件22及电连接件24，电连接件24用于与电致变色膜40电连接，具体而言，电连接件24为弹片，具有导电功能，或以为金属弹片，其一端焊接固定在电路板20上。电连接件24与供电电路21之间通过电路板20内部的走线实现电连接。弹片的弹接端用于抵接至电致变色膜40的供电端口。本实施方式中，电连接件24的数量为四个，四个电连接件24包围形成方形区域，功能器件22设置在此方形区域内部。电连接件24通过电路板内部走线电连接至电路板上的供电电路，或者电连接至功能器件22，供电电路亦可以为功能器件22供电。
其它实施方式中，也可以通过导线或FPC电连接电致变色膜40和电路板20上的电连接点，电连接点可以为焊盘，也可以为连接器。
如图6所示，电致变色膜40的数量可以为一个，即：使用一个尺寸较大的电致变色膜40同时遮挡四个透明部131，贴合工艺简单，亦于操作，节约工时。这个尺寸较大的电致变色膜40包括四个供电端口42，这四个供电端口42分布在电致变色膜40的四个角落位置。
如图7所示，可以理解地，电致变色膜40的数量也可以为四个，四个所述电致变色膜40分别遮挡四个所述透明部131。本实施方式中，通过配置四个较小尺寸的电致变色膜40，四个电致变色膜40分别贴合在四个透明部131处，虽然贴合工艺稍复杂，但可以节约电致变色膜40的材料，降低原料成本。此实施方式中，每个电致变色膜40均包括一个供电端口42，供电端口42位于电致变色膜40的一个角落位置处。这四个电致变色膜40共同形成方形区域，四个供电端口42分布在方形区域的四个角落位置。
具体而言，供电端口42呈弧面状，供电端口42与弹片的抵接面为弧形面，以增加二 者之间的接触面积，提升电致变色膜40与电路板的电连接的稳定性。
本申请利用电致变色膜40在电场作用下，实现颜色和透明度的可逆变化，当智能穿戴产品100未佩戴于人体时，如图8所示，功能器件22不工作，电致变色膜40亦未通电，透明部131处，可见电致变色膜40，在智能穿戴产品100的外表，看不到透明部131的存在，即此时，电致变色膜40与外壳10共同呈现一体化目视效果，电致变色膜40与外壳10外表面的颜色可以为相同的颜色，也可以为不同的颜色，但是依然能呈现一体化视觉效果，例如两种颜色的渐变。当功能器件22工作时(即智能穿戴产品佩戴在人体时)，如图9所示，电致变色膜40通电变为透明色，透明部131的功能此时得到了发挥，功能器件22正常工作，通过透明部131采集人体参数。本申请可以提升智能穿戴产品100的品质和外观体验，提升智能穿戴产品100的竞争力。
电致变色膜40未通电状态下，电致变色膜40与所述外壳10的外表面为同色系。同色系的限定，包括电致变色膜40与所述外壳10的外表面的颜色相同，例如二者均为黑色或其它颜色。同色系亦可以为：电致变色膜40与所述外壳10的外表面的颜色为不同的颜色，但是属于一个色系，同一个色系的相近的颜色组合在一起，也可以使外壳10的外表具有一体化的视感。
请参阅图10，图10是图1和图2所示可穿戴设备100的功能框图。
一种实施方式中，可穿戴设备100可包括一个或多个输入装置102、一个或多个输出装置104和处理器106。一般来讲，输入装置102可检测各种类型的输入，并且输出装置104可提供各种类型的输出。处理器106可从输入装置102接收输入信号，并对输入信号做出相应的响应。例如，处理器106可解释从一个或多个输入装置102接收的输入信号，产生一输出信号，并将该输出信号传输到一个或多个输出装置104。输出信号可使输出装置104提供一个或多个输出。在一个或多个输入装置102处检测到的输入可用于穿戴设备100的一个或多个功能。在一些情况下，一个或多个输出装置104可经组态以提供取决于或回应于由一个或多个输入装置102检测到的输入而被操纵的输出。由一个或多个输出装置104提供的输出还可响应于由处理器106及/或相关联的配套装置执行的程序或应用程序，或由该程序或应用程序起始。
在各种实施例中，输入装置102可包括用于检测输入的任何合适的组件。输入装置102的实例包括音频传感器(例如，麦克风)、光学或视觉传感器(例如，相机、可见光传感器或不可见光传感器)、接近传感器、触碰传感器、触控屏、力传感器、机械装置(例如，表冠、开关、按钮或键)、振动传感器、方位传感器、运动传感器(例如，加速度计或速度传感器)、位置传感器(例如，全球定位系统装置)、热传感器、通讯装置(例如，有线或无线通信装置)、电阻传感器、磁传感器、电活性聚合物(electroactivepolymer，EAP)、应变计、电极等，或其一些组合。每个输入装置102可经组态以检测一个或多个特定类型的输入并提供与检测到的输入对应的信号(例如，输入信号)。例如，可将信号提供给处理器106。

处理器106可以可操作地耦接到输入装置102和输出装置104。处理器106可适用于与输入装置102和输出装置104交换信号。例如，处理器106可从输入装置102接收与输入装置102检测到的输入对应的输入信号。处理器106可解释所接收的输入信号以判定是否响应于输入信号提供及/或改变一个或多个输出。然后，处理器106可向一个或多个输出装置104发送输出信号，以根据需要提供及/或改变输出。此外，可穿戴设备100还可以包括存储器108，用于存储指令和数据。比如，存储器108可以为高速缓冲存储器。存储器108可以保存处理器106刚用过或循环使用的指令或数据。如果处理器106需要再次使用该指令或数据，可从存储器108中直接调用，避免了重复存取，减少了处理器106的等待时间，因而提高了可穿戴设备100的工作效率。
在一些实施例中，输入装置102可包括一组电极。电极可设置在可穿戴设备100的一个或多个外表面上。处理器106可监测在至少一个电极上接收的电压或信号。在一些实施例中，电极之一可永久地或可切换地耦接到装置接地。电极可用于为可穿戴设备100提供心电图(electrocardiogram，ECG)功能。例如，当可穿戴设备100的用户接触从用户接收信号的第一电极和第二电极时，可提供2导联ECG功能。作为另一实例，当可穿戴设备100的用户接触从用户接收信号的第一电极和第二电极以及将用户接地到可穿戴设备100的第三电极时，可提供3导联ECG功能。在2导联和3导联ECG两者的实施例中，使用者可将第一电极压靠在他们身体的第一部分上并将第二电极压靠在他们身体的第二部分上。取决于第三电极位于可穿戴设备100上的位置，可将第三电极压靠在第一或第二身体部分上。
