本申请提出一种按键结构，该按键结构应用于智能手表、智能手环等可穿戴设备，该可穿戴设备具有外壳6，外壳6设有按键孔6a，按键结构活动穿设于按键孔6a。
在本申请的一实施例中，结合图1和图2所示，按键结构包括导电按键1和安装套2，其中，导电按键1包括键帽11和键轴12，键帽11设有导向槽11a，键轴12设于导向槽11a的底壁；安装套2包括支撑部21和绝缘部22，支撑部21具有伸入导向槽11a内的第一端211和穿设于按键孔6a内的第二端，支撑部21设有可供键轴12穿过的轴孔21a；绝缘部22包括设于轴孔21a内周壁的隔离段221，以及延伸并遮盖第一端211面向导向槽11a槽壁的表面的第一延伸段222，隔离段221位于键轴12和轴孔21a的孔壁之间，并与键轴12滑动抵接。
在本实施例中，导电按键1为金属材质，以使用户手指按压导电按键1时，导电按键1可将人体的生物电信号传导给可穿戴设备内的心电检测模块，实现人体心电数据的检测。导电按键1的键帽11和键轴12可一体压铸成型，以节省导电按键1的加工程序和成本，提升导电按键1的结构强度。键帽11背离键轴12一端的端面为平面，以提升用户手指按压键帽11时，用户手指与键帽11的接触面积，提升对用户心电数据采集的准确性和可靠性。键轴12和键帽11可同轴设置，以使键帽11被用户手指按压时能够带动键轴12轴向移动，避免键轴12偏离键帽11轴心移动，而使键轴12与按键孔6a的孔壁间产生更强的挤压和摩擦作用，导致键轴12和外壳6易于磨损的问题。键帽11按图1的竖直方向截断形成的纵截面形状可为圆形或多边形，键轴12按图1的竖直方向截断形成的纵截面形状可为圆形或多边形。
安装套2套设于键轴12外周，用于安装键轴12和给键轴12移动提供导向，安装套2的支撑部21和绝缘部22可为柱状结构，安装套2和绝缘部22按图1的竖直方向截断形成的纵截面形状与键轴12的纵截面形状相适配。支 撑部21的材质可为金属材质，以使支撑部21具有较高的结构强度，以可靠支撑和限位导电按键1。绝缘部22整体嵌套设置于支撑部21的轴孔21a的内周壁，绝缘部22围合形成与轴孔21a同轴的通腔，导电按键1的键轴12穿设于该通腔内。绝缘部22的材质可为塑胶、亚克力等绝缘材质，绝缘部22也可采用低摩擦系数的材质制作，以降低绝缘部22的隔离段221和键轴12之间以及绝缘部22的延伸段和键帽11之间的摩擦阻力，提升导电按键1按压使用时的顺畅性。绝缘部22可通过嵌件注塑的方式在支撑部21上一体注塑成型，使绝缘部22的隔离部紧密贴合于支撑部21的轴孔21a的孔壁，并使绝缘部22的延伸部紧密贴合于支撑部21的第二端的外表面，该第二端的外表面包括第二端面向导向槽11a侧壁的表面和第二端面向导向槽11a底壁的表面，如此可保证支撑部21和绝缘部22之间防水密封的可靠性，避免水分从支撑部21和绝缘部22之间通过并进入可穿戴设备内。
本按键结构在实际使用时，用户按压导电按键1的键帽11，导电按键1的键轴12沿轴孔21a的轴向向移动，导向槽11a的侧壁与第一延伸段222滑动抵接，使键帽11在支撑部21和绝缘部22的导向作用下靠近外壳6移动。当导电按键1被完全按压而使按键结构进入按压状态时，绝缘部22的第一延伸段222与导向槽11a的底壁抵接限位，此时键帽11和外壳6之间具有一定间距，键帽11不与外壳6接触而保持相脱离的状态。以此，支撑部21与键轴12和键帽11之间可通过绝缘部22进行绝缘隔离，外壳6与键轴12之间可通过绝缘部22的隔离段221进行绝缘隔离，外壳6与键帽11之间可通过支撑部21的支撑限位作用和绝缘部22的延伸段的绝缘作用实现绝缘隔离。
本实施例技术方案中导电按键1的键轴12通过绝缘部22的隔离段221与支撑部21和可穿戴设备的外壳6绝缘隔离，导电按键1的键帽11通过绝缘部22的第一延伸段222与支撑部21和可穿戴设备的外壳6绝缘隔离，导电按键1在按压使用时不会与支撑部21或可穿戴设备的外壳6产生电导通，导电按键1和可穿戴设备外壳6间绝缘隔离的可靠性高，有利于提升通过导电按键1检测用户心电数据的准确性。
在本申请的一实施例中，如图1所示，第一端211背向键轴12的一侧设有凸起2113；第一延伸段222遮盖凸起2113背向键轴12的一侧，并与导向 槽11a的侧壁滑动抵接；凸起2113、支撑部21背向键轴12的一侧以及外壳6围合形成避空槽a。
在本实施例中，第一端211上的凸起2113和延伸段遮盖凸起2113的结构设计：一方面，能够在凸起2113和延伸段的支撑隔离下，使导向槽11a面向凸起2113的侧壁与图1所述支撑部21的上表面之间形成一定间距，避免键帽11相对于支撑部21移动时与支撑部21上表面接触而导通，提升支撑部21与导电按键1的键帽11之间的绝缘隔离的可靠性；另一方面，能够使凸起2113、支撑部21上表面以及外壳6围合形成避空槽a，通过避空槽a的槽体内侧空间使键帽11与外壳6之间形成一定间距，避免键帽11与外壳6接触而导通，提升键帽11与外壳6之间绝缘隔离的可靠性。
在本申请的一实施例中，如图1所示，按键结构还包括导电衬套3，导电衬套3套设于键轴12远离键帽11的一端；绝缘部22还包括第二延伸段223，隔离段221位于第一延伸段222和第二延伸段223之间，第二延伸段223遮盖第二端背向导向槽11a底壁的一侧，并位于第二端和导电衬套3之间，以使导电衬套3与按键孔6a的周缘之间形成间隔空间b。
在本实施例中，导电衬套3用于延伸键轴12的长度以及防止键轴12滑脱于外壳6，具体地，导电衬套3位于外壳6内的安装腔内，导电衬套3和键帽11分别位于按键孔6a的相对两侧，导电衬套3的直径大于轴孔21a的孔径，以使导电衬套3无法通过按键孔6a，如此当键轴12向轴孔21a外侧移动时，导电衬套3能够与轴孔21a的周缘止挡限位，防止键轴12向外滑脱于轴孔21a，保证导电按键1使用时的可靠性。导电衬套3可通过螺接、卡接等方式与键轴12可拆卸连接，以提升键轴12与导电衬套3相安装和相拆卸的便捷性。导电衬套3的材质可为金属材质，以使导电衬套3能够将键帽11和键轴12上的生物电信号传导给可穿戴设备内的心电检测模块，实现可穿戴设备的心电检测功能。
第一延伸段222、隔离段221以及第二延伸段223可为一体成型结构，第二延伸段223遮盖第二端背向导向槽11a底壁的一侧设置，一方面，使第二延伸段223能够绝缘隔离导电衬套3和支撑部21，防止键轴12和导电衬套3移动时导电衬套3与支撑部21接触和导通，保证支撑部21和导电衬套 3之间绝缘隔离的可靠性；另一方面，在第二延伸段223的支撑下，导电衬套3与按键孔6a的周缘之间形成间隔空间b，从而能够避免键轴12和导电衬套3移动时导电衬套3与外壳6接触和导通，保证导电衬套3和外壳6之间的绝缘隔离的可靠性。
在本申请的一实施例中，如图1所示，隔离段221远离第二端的一端设有第一限位台阶2211；按键结构还包括弹性件4，弹性件4套设于键轴12，并限位于第一限位台阶2211和导向槽11a的底壁之间。
在本实施例中，第一限位台阶2211位于轴孔21a内侧，第一限位台阶2211用于对弹性件4端部进行限位，同时约束弹性件4的形变方向，使弹性件4沿轴孔21a的轴向压缩或伸展，从而通过键帽11驱动键轴12轴向移动。当导电按键1被按压而使按键结构进入按压状态时，弹性件4压缩，当导电按键1上的按压力撤除时，弹性件4弹性恢复并驱动键帽11带动键轴12复位，如此实现导电按键1的自动复位。其中，弹性件4可为套设于键轴12上的弹簧或弹性套筒等。
在本申请的一实施例中，如图1所示，第一端211包括呈夹角设置的限位段2111和导向段2112，限位段2111位于导向段2112和第一端211之间；限位段2111与外壳6抵接限位，导向段2112伸入导向槽11a内；隔离段221远离第二端的一端沿限位段2111和导向段2112的内壁设置，以形成第一限位台阶2211。
在本实施例中，限位段2111和导向段2112均为环状结构，限位段2111和导向段2112之间的夹角为在图1所示截面状态下，限位段2111面向导向槽11a底壁的壁面与导向段2112面向键轴12的内壁面所呈的角度。限位段2111与导向段2112之间的夹角可为非0度和非180度的任意夹角，比如限位段2111与导向段2112之间的夹角可为90度。通过使第一端211包括呈夹角设置的限位段2111和导向段2112，可使第一端211相对于第二端扩张，使限位段2111和导向段2112的连接处形成L形台阶结构，从而在将绝缘部22的隔离段221沿限位段2111和导向段2112的内壁设置时，使隔离段221上形成上述第一限位台阶2211，通过第一限位台阶2211限位弹性件4。此外，在 弹性件4为金属材质时，还能够通过隔离段221上的第一限位台阶2211的结构隔离弹性件4和支撑部21，防止弹性件4与支撑部21接触而导通导电按键1和支撑部21，提升导电按键1与支撑部21之间绝缘隔离的可靠性。
在本申请的一实施例中，结合图1和图2所示，按键孔6a的孔壁设有连续设置的第二限位台阶61和第三限位台阶62；限位段2111至少部分容纳并限位于第二限位台阶61，并与第三限位台阶62围合形成容置空间6b；按键结构还包括密封圈5，密封圈5设于容置空间6b内，并与第三限位台阶62和支撑部21密封抵接。
在本实施例中，第二限位台阶61用于限位支撑部21的限位段2111，第三限位台阶62用于限位密封圈5，第二限位台阶61和第三限位台阶62连续设置，以使限位部至少部分限位于第二限位台阶61时，限位部与第三限位台阶62的壁面可围合形成可容置密封圈5的容置空间6b。第二限位台阶61的设置，一方面，能够对支撑部21的限位段2111进行限位固定，提升支撑部21在外壳6上安装固定的可靠性；另一方面，使限位段2111的至少部分结构容纳并限位于第二限位台阶61处，能够缩减整个按键结构外露于可穿戴设备壳体的体积，从而有利于缩减可穿戴设备的整体体积。
支撑部21的外周壁可设置外螺纹，按键孔6a的内周壁可设置内螺纹，支撑部21通过外螺纹和内螺纹的配合与按键孔6a的内周壁螺接，当将支撑部21向按键孔6a内拧紧时，支撑部21的限位段2111将挤压预置在第三限位台阶62上的密封圈5，使密封圈5被紧密夹持限位在限位段2111和第三限位台阶62的壁面之间，实现密封圈5的安装固定，保证外壳6与支撑部21之间的防水密封。
本申请还提出一种可穿戴设备，该可穿戴设备包括但不限位于为智能手表和智能手环。
在本申请的一实施例中，结合图1和图2所示，该可穿戴设备包括外壳6和上述各实施例中的按键结构，外壳6设有安装腔和与安装腔连通的按键孔6a；按键结构的支撑部21穿设于按键孔6a内。
在本实施例中，按键孔6a用于安装上述按键结构，按键结构安装于按键 孔6a处时，导电按键1的键帽11位于外壳6外侧，用户可通过按压或扭动键帽11来驱动键轴12轴向移动或旋转。键轴12穿过安装套2的轴孔21a，并可在转动或沿轴孔21a的轴向移动时被可穿戴设备安装腔内的传感器8组检测到，而通过与传感器8组电连接的功能模块可使穿戴设备能够响应导电按键1的按压和旋转操作，进一步控制可穿戴设备上的显示器、扬声器等执行终端相应执行画面显示、发声等动作，实现可穿戴设备与用户之间的信息交互。其中，该按键结构的具体结构参照上述实施例，由于可穿戴设备采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
在本申请的一实施例中，结合图1和图2所示，可穿戴设备包括安装支架7、传感器8以及第一导电弹片9，安装支架7设于安装腔内，安装支架7面向按键孔6a的一侧设有通槽7a；传感器8设于通槽7a内；第一导电弹片9设于安装支架7，并部分限位于通槽7a内，第一导电弹片9位于键轴12和传感器8之间；其中，导电按键1具有键轴12与第一导电弹片9抵接的按压状态，在按压状态时，第一导电弹片9与传感器8抵接并导通。
在本实施例中，安装支架7用于安装固定传感器8和第一导电弹片9，安装支架7可通过螺接、卡接等方式安装固定于安装腔的腔壁，实现安装支架7与外壳6的连接固定。安装支架7在外壳6上固定时，安装支架7的通槽7a的槽口朝向安装套2的轴孔21a设置，传感器8可安装固定于通槽7a的底壁，第一导电弹片9可设置于传感器8和键轴12上的导电衬套3之间，导电衬套3部分位于通槽7a内，并可在键轴12轴向移动时沿通槽7a靠近或远离传感器8移动，以使导电衬套3能够在靠近键轴12轴向移动时挤压第一导电弹片9，使第一导电弹片9形变并与传感器8接触和导通，以将用户手指传导给键帽11和键轴12的生物电信号进一步传导给传感器8，进而可通过与传感器8电连接的心电检测模块获取用户的心电数据，同时也可通过传感器8感知到用户按压导电按键1的操作，通过与传感器8电连接的相关功能模块可使穿戴设备能够响应导电按键1的按压操作，实现可穿戴设备与用户的交互。
在本申请的一实施例中，结合图2和图3所示，第一导电弹片9包括连接段91和两个装配段92，连接段91设有通孔91a，通孔91a的孔壁设有弹性触片911；两个装配段92分别设于连接段91的相对两端，通槽7a的相对两侧壁均设有凸部71，两个凸部71位于键轴12和传感器8之间，每一装配段92与安装支架7连接，以使连接段91的两端分别与两个凸部71抵接限位，并使通孔91a和弹性触片911位于两个凸部71之间；在按压状态时，键轴12抵接并挤压弹性触片911，以使弹性触片911与传感器8抵接并导通。
在本实施例中，键帽11被用户手指按压时键轴12轴向移动，键轴12带动导电衬套3靠近并挤压弹性触片911，使弹性触片911形变并部分伸出于通孔91a与传感器8接触，弹性触片911通过连接段91以及装配段92与心电检测模块连接，从而使键帽11、键轴12、导电衬套3、弹性触片911以及传感器8依次接触和导通，以通过与传感器8电连接的心电检测模块获取用户的心电数据
通槽7a的相对两侧壁设有凸部71，两个凸部71间隔设置，传感器8位于两个凸部71之间，两个凸部71与通槽7a的侧壁配合形成台阶结构，连接段91的两端与凸背部向通槽7a底壁的一侧抵接，使连接段91的两端限位于该台阶结构处。导电衬套3轴向移动并挤压弹性触片911时，因为连接段91的两端被凸部71止挡限位而固定不动，因此弹性触片911的部分结构将形变并从两个凸部71之间穿过，使弹性触片911最终与传感器8接触而导通。
在本申请的一实施例中，结合图1和图3所示，可穿戴设备还包括第二导电弹片10和心电检测模块；第二导电弹片10设于安装腔内，并与一装配段92抵接；心电检测模块与第二导电弹片10和传感器8电连接。
在本实施例中，心电检测模块始终与第二导电弹片10及传感器8保持电连接，在导电按键1不被按压时，键轴12上的导电衬套3与弹性触片911脱离，弹性触片911与传感器8脱离，此时第二导电弹片10和传感器8之间为断路状态，心电检测模块不工作。当导电按键1处于按压状态时，键轴12上的导电衬套3与弹性触片911接触，弹性触片911与传感器8接触，传感器8和心电检测模块通过第二导电弹片10导通并形成电路回路，从而使心电检测模块能够通过第二导电弹片10和传感器8获取导电键轴12上的传导的生物 电信号，实现本可穿戴设备的心电检测功能。其中，心电检测模块可包括用于心电检测的ECG(electrocardiogram，心电图)芯片和相关控制电路。
以上所述仅为本发明的可选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
