一个或多个实施例通过与之对应的附图中的图片进行示例性说明，这些示例性说明并不构成对实施例的限定，附图中具有相同参考数字标号的元件表示为类似的元件，除非有特别申明，附图中的图不构成比例限制。
具体实施方式
下面将结合附图对本发明的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
心电信息的检测原理是，心脏在收缩和舒张时，有微小的生物电产生，这将引起一系列电位变化，这一系列的电位变化经过生物组织可传输至体表。采集被测对象的身体表面不同部位的心电信号，根据所述心电信号可获得被测对象的心电信息。在实际应用中，通常是在被测对象的身体表面至少三个部位设置电极，通过电极可采集到被测对象的心电信号，再根据所述心电信号计算获得被测对象的心电信息。
图1为一种典型的可穿戴电子设备的剖视图。如图1所示，所述可穿戴电子设备10包括本体11、第一连接带12和第二连接带13，第一连接带12和第二连接带13分别与本体11的两侧相连接。本体11包括第一电极111、第二电极112、第一连接部113、第二连接部114、PCB电路板115和电池116。第一电极111和第二电极112设置在本体11的底部，第一电极111和第二电极112分别与第一连接部113和第二连接部114电接触，第一连接部113和第二连接部114均与PCB电路板115电连接，因此第一电极 111和第二电极112均与PCB电路板115电连通；本体11还包括第三电极(图中未画出)，所述第三电极可以设置在本体11的侧面，且与PCB电路板115电连通；PCB电路板115上设置有可用于心电检测的芯片(图中未画出)，所述芯片通过第一电极111、第二电极112和第三电极计算获取被测对象的心电信息；电池116与PCB电路板115相连接，电池116用于为心电检测电路提供电源。
示例性的，所述可穿戴电子设备10可以是智能手表，本体11是所述智能手表的表头，第一连接带12和第二连接带13是所述智能手表的两根表带。
示例性的，第一电极111、第二电极112、第一连接部113和第二连接部114可以是金属部件等导体，第三电极可以是设置在本体侧面的金属按键。
在一种可能的应用场景中，所述可穿戴电子设备佩戴在被测对象的左手腕处时，设置在本体的底部的第一电极111和第二电极112与被测对象的左手腕处的皮肤接触。当被测对象的右手触摸到所述第三电极时，第一电极111和第三电极分别采集到被测对象的不同部位的心电信号，第二电极112根据第一电极111和第三电极所采集到的心电信号求和获得共模信号的大小，并将所述共模信号反馈至检测电路，从而消除检测电路中的共模干扰。可穿戴电子设备10根据采集到的心电信号计算获得被测对象的心电信息。
在采集被测对象的体表的不同部位的心电信号的过程中，被测对象相当于一个信号源，与可穿戴电子设备共同构成检测电路。所述信号源的内阻，包括可穿戴电子设备的电极与被测对象的皮肤所形成的接触阻抗。当可穿戴电子设备的电极与被测对象的皮肤所形成的接触阻抗越大时，接触阻抗本身具有的热噪声也越大，此时电极所采集到的心电信号的幅度较小且有较大的噪声干扰，可穿戴电子设备的检测精度将大大降低。在实际的应用场景中，设置于本体底部的第一电极和第二电极与被测对象的皮肤的佩戴贴合度往往较差，也即是第一电极和第二电极与被测对象的皮肤接触不良。此时，第一电极与被测对象的皮肤接触的有效电极面积较小，导致第一电极与被测对象的皮肤所形成的接触阻抗较大，第一电极所采集到的心电信号的幅度较小且具有较大的噪声干扰；另外，第二电极与被测对象 的皮肤接触不良，导致第二电极无法将共模信号反馈至检测电路中，从而无法消除回路中的共模信号的干扰，因此第一电极和第二电极与被测对象的皮肤接触不良，降低了心电检测的精度。设置在本体底部的第一电极和第二电极与被测对象的皮肤接触不良，是导致可穿戴电子设备的心电检测精度不高的痛点问题。
针对上述问题，本申请通过增大第一电极和第二电极的面积，来增大第一电极和第二电极与被测对象的皮肤的有效接触面积，使得第一电极和第二电极与被测对象的皮肤接触良好，从而提高检测精度。

本体41上还包括设置在本体一侧的第三电极44，具体地，第三电极44为本体侧面的金属按键。
在实际应用中，所述可穿戴电子设备可佩带在被测对象的手腕处，第一电极和第二电极与手腕处的皮肤接触。当被测对象主动触摸第三电极44时，第一电极和第三电极44分别采集到被测对象的不同部位的心电信号，第二电极根据第一电极和第三电极44所采集到的心电信号求和获得共模信号的大小，并将所述共模信号反馈回检测电路，从而消除检测电路中的共模干扰，PCB电路板414根据采集到的心电信号计算获得被测对象的心电信息。
在本申请实施例中，通过将第一电极和第二电极从本体底部延伸至被连接带上，增大了第一电极和第二电极的面积，使得第一电极和第二电极与被测对象的皮肤的接触良好，增大了第一电极所采集到的心电信号的幅度且减小了噪声干扰，且第二电极能反馈共模信号的大小至检测电路从而消除了检测电路中共模信号的干扰，提高了心电检测的精度；且第一电极和第二电极关于本体底部的中心轴呈对称分布，使得第一电极和第二电极在工艺较易实现，且外观上更为美观；此外，第一电极设置在本体底部的接触端和连接带的接触端所采集到的心电信号可相互补偿，因此第一电极能稳定采集到高质量的心电信号，即使是在接触不良的情况也是如此，因此本申请实施例所提供给的可穿戴电子设备具有良好的检测稳定性和较高的检测精度。
本申请实施例通过在本体底部设置第一公端415和第二公端416，以及在第一连接带和第二连接带上分别设置第一母端421和第二母端431，从而实现第一接触端410和第三接触端420电连通形成第一电极，第二接 触端411和第四接触端430电连通形成第二电极，此方案在工艺上易于实现。
作为一种优选的实施例，在第一金属触点所处的平面上，第一金属触点与第一公端415之间的空隙中充满防水绝缘物质；在第二金属触点所处于的平面上，第二金属触点与第一母端421之间的空隙中充满防水绝缘物质；在第三金属触点所处于的平面上，第三金属触点与第二公端416之间的空隙中充满防水绝缘物质；在第四金属触点所处于的平面上，第四金属触点与第二母端431之间的空隙中充满防水绝缘物质，从而达到防水的效果。
可选地，所述防水绝缘物质可以是透明UV胶。
当第一公端415、第二公端416、第一母端421或者第二母端431与其对应的金属触点不能完全匹配时，也即第一公端415、第二公端416、第一母端421或者第二母端431与其对应的金属触点之间存在空隙时，那么液体例如汗液等可以通过所述空隙进入可穿戴电子设备内，导致可穿戴电子设备内部短路。所以将所述空隙填充满防水不导电物质，可以有效防止液体进入可穿戴电子设备，从而防止由之而引起的内部短路的现象。
需要说明的是，在不冲突的前提下，本申请描述的各个实施例和/或各个实施例中的技术特征可以任意的相互组合，组合之后得到的技术方案也应落入本申请的保护范围。
应理解，本申请实施例中的具体的例子只是为了帮助本领域技术人员更好地理解本申请实施例，而非限制本申请实施例的范围，本领域技术人员可以在上述实施例的基础上进行各种改进和变形，而这些改进或者变形均落在本申请的保护范围内。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
