本申请的技术构思是：本申请的透光电极结构集成了ECG电极和心率透 光镜片两种功能，既能够检测人体表面的电信号用于ECG测量，又能够使光学心率传感器实现光发射和接收，从而将ECG测量和心率测量集中到同一电极结构中，实现空间的节约。
图1至图5示出了本申请透光电极结构的一个示意性实施例。
如图1至图5所述，本申请的透光电极结构用于安装在电子设备的外表面，包括：基座100、透明电极层200和导电连接件300。透明电极层200覆盖在基座100的外表面。导电连接件300穿过基座100，电连接透明电极层200与电子设备内的ECG电路，使透明电极层200形成ECG电极。并且，基座100设置有若干透光通孔130，透光通孔130对准电子设备内的光学心率传感器，使透明电极层200形成光学心率传感器的透光镜片。
从而，在本实施例的透光电极结构中，基座100上设置的透明电极层200既能够导电，通过导电连接件300与电子设备内部的ECG电路连接，实现ECG测量功能，同时，该透明电极层200又能够结合基座100上的透光通孔130，使心率测量所用的光无障碍通过，实现心率测量。由此，本实施例将ECG电极和心率测量透光镜片的功能合二为一，有效减小了健康测量装置的体积，有利于可穿戴健康设备的小型化和轻量化设计。
在本申请的一个实施例中，透明电极层200为非金属导电薄膜，通过膜内嵌件注塑工艺覆盖在基座100的外表面。膜内嵌件注塑工艺(In Molding Label，缩写IML)，是一种在注塑模具内放置薄膜来装饰塑胶外观表面的新技术，其成型的特点是，成型结构表面是一层透明薄膜，中间是印刷图案层，背面是塑胶层，由于图案层位于内部，不易磨损褪色，成型结构更加经久耐用。
在本申请的一个实施例中，基座100与透明电极层200之间，除去透光通孔130区域外，均印刷着有色导电油墨。有色导电油墨可以遮蔽电子设备的内部结构，避免因透明电极层200透视电子设备内部结构造成的不良外观影响。
参考图1至图2所示，透明电极层200上的虚线区域为不设油墨区域220，该不设油墨区域220对准透光通孔130，因为要保证心率测量光的顺利透过而不印刷有色导电油墨。由于本实施例采用IML工艺，有色导电油墨夹在透明电极层200和基座100中间，可有效防止有色导电油墨被刮花，提高耐摩 擦性，长期保持有色导电油墨的颜色鲜明不易退色，提高电子设备的外观设计水平。
在本申请的一个实施例中，透明电极层200包括完整的一块或拼接在一起的多块，从而形成一个或多个ECG电极。当采用多块拼接的透明电极层200时，参考图1至图5所示，多块透明电极层200之间通过阻断筋140绝缘隔离，且每块透明电极层200均连接一个独立的导电连接件300。在图1至图5所示实施例中，透明电极层200包括拼接在一起的两块，分别通过两个独立的导电连接件300形成两个ECG电极。
在本申请的一个实施例中，如图2至图3所示，基座100设置有电连接通孔120，导电连接件300为导电泡棉，导电泡棉穿过电连接通孔120电连接透明电极层200与电子设备内的ECG电路。
或者，在本申请的其他一些实施例中，基座100设置有贯通凹槽，导电连接件300为弹性导电胶水，弹性导电胶水灌注进贯通凹槽电连接透明电极层200与电子设备内的ECG电路。
在本申请的一个实施例中，如图1、图2和图4所示，基座100上设置有若干充电针110，充电针110连接电子设备内的充电电路，透明电极层200设置有供充电针110露出的充电孔210，以实现电子设备的接触充电。从而，在本申请透光电极结构的实施例中，进一步集成充电模块，更加有效地提高透光电极结构的空间利用率。
在本申请的一个实施例中，基座100为塑胶材质。阻断筋140为基座100的一部分，通过注塑等方式一体成型。本实施例使用塑胶材质的基座100以及非金属材质的透光电极层200，替代现有设计中的金属电极，减少了金属材质的使用，不仅使电子设备的体重减轻，也有利于缩减产品的成本。
本申请还公开了一种智能穿戴设备，在本申请的一个实施例中，该智能穿戴设备包括ECG电路和光学心率传感器，智能穿戴设备的外壳包括如上任一项的透光电极结构。从而，该智能穿戴设备的实施例可以通过上述透光电极结构同时实现ECG测试和心率测试，甚至还可以实现接触充电，因而可以更加轻量化和小型化。
在本申请的一个实施例中，该智能穿戴设备为智能手表，透光电极结构设置在智能手表贴合手腕的一侧。
在本申请的一个实施例中，透光电极结构通过防水胶密封粘接在智能穿戴设备上，从而实现智能穿戴设备的防水防尘。
在本申请的一个实施例中，该智能穿戴设备的光学心率传感器包括一个或多个发光二极管。透光电极结构上的透光通孔130根据光学心率传感器的结构设置，在本申请图1至图5所示实施例中，透光通孔130设置有五个，在本申请的其他实施例中，透光通孔130可以设置为其他数量和其他排列形式，在此不一一赘述。
综上所述，本申请的透光电极结构集成了ECG电极和心率透光镜片两种功能，既能够检测人体表面的电信号用于ECG测量，又能够使光学心率传感器实现光发射和接收，从而将ECG测量和心率测量集中到同一电极结构中，实现空间的节约。此外，在本申请的优选实施例中，透明电极层为非金属导电薄膜，基座为塑胶基座，从而替代了现有技术中的金属电极，减少了金属材质的使用，减轻了电子设备的重量，也降低了电极成本。
以上所述，仅为本发明的具体实施方式，在本发明的上述教导下，本领域技术人员可以在上述实施例的基础上进行其他的改进或变形。本领域技术人员应该明白，上述的具体描述只是更好的解释本发明的目的，本发明的保护范围应以权利要求的保护范围为准。
