在本实施例中，第一凹槽3212可设置于按键杆321的外壁，或者第一凹槽3212可设置于第一段3121的腔壁，或者按键杆321的外壁和第一段3121的腔壁上均设有第一凹槽3212，且呈对应设置，在此不做限定。可以理解的，第一密封圈6具有弹性和密封性，第一密封圈6容纳于第一凹槽3212内，并部分凸出第一凹槽3212的槽口，使得凸出第一凹槽3212的槽口的第一密封圈6能够与按键杆321的外壁或第一段3121的腔壁密封抵接。
可选地，第一凹槽3212可以使U型凹槽、楔形槽、V型槽、弧形槽、半圆型槽等，在此不做限定。

在本实施例中，如图3至图5所示，通过在按键帽322的外壁设置避让槽3221，从而方便第二卡接件323的弹性避位，确保第二卡接件323顺利伸入第二段3111内并与第一卡接件315卡接。可以理解的，第二卡接件323的弹臂3231一端与按键帽322的外壁连接，另一端为自由端，卡凸3232凸设于弹臂3231的自由端，使得弹臂3231与按键帽322的外壁齐平，从而在施加外力按压按键帽322时，按键帽322能够沿第二段3111滑动，避免第二卡接件323干涉按键帽322的滑动。
可选地，第一卡接件315呈环形凸台设置，也即第一卡接件315沿第二段3111内壁的周向延伸设置。当然，在其他实施例中，第一卡接件315包括多个凸台结构，多个凸台结构沿第二段3111内壁的周向间隔设置，此时每一凸台结构与一第二卡接件323对应。
可以理解的，第二卡接件323包括多个，多个第二卡接件323沿按键帽322的外壁周向 间隔设置，按键帽322的外壁对应每一第二卡接件323设有一避让槽3221，在此不做限定。在本实施例中，为了方便第二卡接件323的卡凸3232顺利伸入第二段3111内并与第一卡接件315卡接，卡凸3232设有导向面3233，也即在安装按压件32时，第一卡接件315沿卡凸3232的导向面3233移动，以使得卡凸3232滑入第二段3111，并与第一卡接件315卡接。
在一实施例中，如图3至图5所示，第一段3121与第二段3111的连通处形成有抵接面3112，按压按键帽322时，按键帽322与抵接面3112抵接。可以理解的，如此设置，从而利用抵接面3112限制外力的挤压，避免外力过大，使得按键帽322带动按键杆321过渡抵压触发组件2，进而损坏触发组件2。如此在施加外力按压按键帽322时，按键帽322的外壁沿第一卡接件315滑动，并与抵接面3112抵接，此时按键杆321刚好可以抵压触发触发组件2。
在一实施例中，旋转表冠31包括相连接的旋转部311和转轴部312，滑动腔31a贯穿旋转部311和转轴部312，旋转部311与转轴部312的连接处形成有限位面313，转轴部312可转动地穿设于按键孔11内，使限位面313与壳体1的外壁限位抵接。

可以理解的，旋转表冠31的旋转部311外径大于转轴部312的外径。可选地，旋转表冠31的转轴部312呈圆柱状的筒形结构。在本实施例中，旋转表冠31的旋转部311和转轴部312为一体成型结构，如此可提高旋转表冠31的结构强度。
在一实施例中，转轴部312穿过按键孔11的一端外壁设有卡槽3122，按键结构100还包括设于壳体1内的卡簧4，卡簧4活动卡接于卡槽3122内。
在本实施例中，如图2至图5所示，通过在转轴部312上设置卡槽3122，并设置卡簧4，利用卡簧4活动卡接于卡槽3122内，并与壳体1的内壁抵接限位，如此可利用卡簧4进一步将旋转表冠31限定于按键孔11内，避免施加外力拉动按键组件3的旋转表冠31和/或按压件32时，避免将按键组件3从按键孔11内拉出。
可以理解的，通过设置卡簧4，使得卡簧4可拆卸地卡接于旋转表冠31的卡槽3122内，从而方便按键组件3的安装与拆卸。当然，在其他实施例中，也可通过在转轴部312穿过按键孔11的一端外壁凸设限位台，使得限位台与壳体1的内壁限位抵接，也即限位台、转轴 部312及旋转部311围合形成H型限位槽结构，从而确保旋转表冠31的安装和限位，在此不做限定。
在本实施例中，卡槽3122沿转轴部312的外壁周向设置并形成环槽，卡簧4具有卡接部41，卡接部41呈U型设置，卡接部41活动卡接于卡槽3122内。也即卡簧4具有卡接部41和连接卡接部41的安装部，卡簧4通过安装部与壳体1的内壁限位安装或抵接限位，卡簧4的卡接部41呈U型设置，使得U型卡簧4卡接于旋转表冠31中转轴部312的卡槽3122内，一方面能够限位旋转表冠31沿按键孔11轴向的移动，另一方面有可以实现旋转表冠31沿按键孔11周向的转动。
在一实施例中，如图1、图3至图5所示，按键结构100还包括耐磨片5，耐磨片5套设于转轴部312，并夹设于限位面313和壳体1的外壁之间。可以理解的，如此设置，从而利用耐磨片5降低旋转表冠31旋转时与壳体1外壁的摩擦，从而降低旋转阻尼力。可选地，耐磨片5的材质为PEEK材质。
在本实施例中，如图4和图5所示，限位面313设有限位槽314，耐磨片5的部分容纳于限位槽314内。可以理解的，通过设置限位槽314，从而方便利用限位槽314对耐磨片5实现定位和限位安装，同时部分耐磨片5凸出限位槽314的槽口，如此可使得耐磨片5与壳体1的外壁抵接，避免限位面313直接与壳体1的外壁直接接触，从而有效降低摩擦。
在一实施例中，按键结构100还包括至少一个第二密封圈7，第二密封圈7夹设于转轴部312的外壁和按键孔11的孔壁之间。
在本实施例中，如图3至图5所示，通过设置第二密封圈7，从而利用第二密封圈7密封旋转表冠31的转轴部312和按键孔11的孔壁之间的缝隙，提高密封性能和防水性能。可选地，第二密封圈7的材质为NBR。
可以理解的，第二密封圈7位于旋转表冠31中的转轴部312的卡槽3122和旋转部311之间。可选地，第二密封圈7包括多个，多个第二密封圈7沿转轴部312的延长方向间隔排布。
为了避免旋转表冠31旋转过程中第二密封圈7发生移位现象，导致密封性降低等问题，在一实施例中，如图3至图5所示，转轴部312的外壁和按键孔11的孔壁中至少一个设有第二凹槽3123，第二密封圈7容纳于第二凹槽3123内，并部分凸出第二凹槽3123的槽口。
可以理解的，第二凹槽3123可设置于旋转表冠31的转轴部312的外壁，或者第二凹槽3123可设于按键孔11的孔壁，或者第二凹槽3123同时设置于转轴部312的外壁和按键孔11的孔壁，此时两个第二凹槽3123对应，在此不做限定。
在本实施例中，第二密封圈7具有弹性和密封性，第二密封圈7容纳于第二凹槽3123 内，并部分凸出第二凹槽3123的槽口，使得凸出第二凹槽3123的槽口的第二密封圈7能够与转轴部312的外壁和按键孔11的孔壁密封抵接。
可选地，第二凹槽3123可以使U型凹槽、楔形槽、V型槽、弧形槽、半圆型槽等，在此不做限定。
在一实施例中，如图1至图4所示，触发组件2包括触发元件21和光学传感器22，其中，触发元件21设于壳体1内，并与按键孔11正对设置，光学传感器22设于壳体1内，并与旋转表冠31的侧壁正对设置。
在本实施例中，触发元件21对应按键孔11设有触片，触片与按键杆321远离按键帽322的一端正对。可以理解的，触发元件21和光学传感器22与电路板电连接，从而使得电路板用于接收触发元件21和光学传感器22的触发信号，用于实现触发信号相应的控制功能。可选地，电路板为柔性电路板或硬质电路板，在此不做限定。
可以理解的，触发元件21可焊接于柔性电路板上，以使得触发元件21对应按键孔11设有触片，触片与按键杆321远离按键帽322的一端正对，如此在施加外力按压按键帽322时，按键杆321与触片抵接并按压触发信号。
在本实施例中，通过设置光学传感器22，从而利用光学传感器22检测和识别用户旋转旋转表冠31时带动转轴部312旋转，以触发不同于按压触发触发元件21的信号或功能，在此不做限定。可以理解的，光学传感器22设于电路板，并与触发元件21相邻且间隔设置，光学传感器22用于感应旋转表冠31的转轴部312旋转，以触发触发组件2。
可以理解的，如此设置，使得按压按压件32的移动行程设置在旋转表冠31内，如此可使得壳体1不需要保证按压按压件32所需要的行程，可使得设备的壳体1厚度进一步减薄，节省设备内部空间。同时，将弹性件33和按压件32均设置于旋转表冠31的滑动腔31a内，从而使得旋转表冠31旋转时，一并带动弹性件33和按压件32旋转，有效避免了弹性件33与按压件32之间的摩擦，提高可以保证良好的旋转手感，提高旋转表冠31的旋转寿命。
本实施例中按键结构100组装时，将弹性件33和第一密封圈6与按压件32组装，再将组装好的按压件32装入旋转表冠31的滑动腔31a内，使按键帽322上的第二卡接件323与旋转表冠31滑动腔31a内的第一卡接件315扣合；再将耐磨片5、第二密封圈7安装于旋转表冠31的相依相应位置，将组装好的旋转表冠31安装于壳体1的按键孔11内，从壳体1内侧插入耐磨卡簧4，再将卡簧4与壳体1焊接固定。再将触发组件2的光学传感器22和触发元件21安装于壳体1内部相应位置。
安装后的按键结构100中，由于按键帽322安装时弹性件33处于预压缩状态，旋转表冠 31与按键帽322相互支撑，旋转表冠31转动时，其滑动腔31a的按键杆321和弹性件33会与旋转表冠31同步转动。安装于壳体1内部的光学传感器22接受旋转表冠31的旋转信号，从而实现旋转信号输入；手动按压按压件32的按键帽322，按键杆321轴向运动，触发触发元件21，从而输入开关信号。撤去外力松开后，弹性件33回弹，并推动按键杆321复位到初始位置。安装在旋转表冠31和按键杆321外侧的第二密封圈7和第一密封圈6在保证按键组件3运动的同时，可保证了5ATM级别的防水。
可以理解的，按键结构100由于旋转表冠31在按键孔11轴向不运动，所以壳体1的厚度可减小，从而节省壳体1内部空间，有利于内部器件堆叠；由于旋转表冠31在按键孔11的轴向不受力，所以旋转阻尼小，旋转手感较好，并且不易磨损，使用寿命提高；按键组件3零件集成度高，可组件化来料，物料管理成本低，组装便捷。
本申请还提出一种穿戴设备，该穿戴设备包括设备主体和上述的按键结构100，该按键结构100的具体结构参照前述实施例，由于本穿戴设备采用了前述所有实施例的全部技术方案，因此至少具有前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。
在本实施例中，设备主体包括壳体，壳体设有按键孔，按键结构100连接于壳体。可以理解的，穿戴设备可以是手表、手环、头戴显示器等，穿戴设备为手表时，壳体可以是手表的表壳。
