鼠标作为电脑的一种输入结构，可以对电脑屏幕上的光标进行定位，鼠标通常包括有按键和滚轮等结构。随着电子产品轻薄化的发展趋势，鼠标的高度也在逐渐降低。
然而，现有鼠标内的按键高度通常较高，难以兼容对体积要求较高的鼠标产品。

在本公开的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”以及“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。
此外，术语“第一”和/或“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”和/或“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
在本公开中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”和/或“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本公开中的具体含义。
在本公开中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第 一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
实施例中提供了一种按键结构，可用于鼠标中，具体的，可用作鼠标中左键和右键位置的操作按键。使用中，按键结构可安装于鼠标的基板40上，基板40可以是鼠标中的主板。
如图1和图2所示，按键结构包括执行机构10和感应机构20。其中，执行机构10可设置于基板40的一侧，感应机构20可设置于基板40的另一侧。使用时，基板40通常是固定安装于鼠标底壳(图未示)上，且基板40与鼠标底壳之间会留有间隙。执行机构10通常位于基板40远离鼠标底壳的一侧，以便于用户通过鼠标上盖操作执行机构10，位于基板40靠近鼠标上盖一侧的按键高度也会影响鼠标的整体高度。使用中，执行机构10可配置成触发感应机构20，从而以实现输入。
现有技术中通常将感应机构20设置于基板40靠近执行机构10的一侧，且集成于执行机构10内部，因感应机构20需要占用一定的空间高度，从而使得执行机构10的整体高度加高，即在基板40靠近鼠标上盖一侧占用更高的空间，也会使得鼠标的整体高度较高。
而本公开中，将感应机构20设置于基板40远离执行机构10的一侧，即使得感应机构20相对于执行机构10外置。从而可降低执行机构10的高度，相应的，也可使基板40到鼠标上盖的距离缩小，即降低鼠标的整体高度。同时，感应机构20位于基板40与鼠标底壳之间的间隙中，可对该部分空间进行利用，提高鼠标内部的空间利用。
再一并结合图3所示，执行机构10包括有中轴13，中轴13相对于基板40伸缩安装。相对于基板40设置有感应机构20的一侧，中轴13可伸出或缩回。可以理解的是，当中轴13延伸至基板40设置有感应机构20的一侧时为伸出，当中轴13未延伸至基板40设置有感应机构20的一侧时为缩回。使用中，当中轴13相对于基板40伸出时，中轴13可触发感应机构20，并由感应机构20产生感应信号，可作为鼠标的一输入信号。
如图1至图3所示，执行机构10还可包括壳体组件11、键帽12和弹性件14。其中，壳体组件11的一端可固定连接于基板40上，中轴13滑动安装于壳体组件11内，且中轴13可在壳体组件11靠近基板40的一端伸出和缩回。键帽12安装于壳体组件11远离基板40的一端，且键帽12与中轴13远离基板40的一端固定连接。在键帽12未被按压时，键帽12远离基板40的一端凸出于壳体组件11的端面设置，以便于在鼠标的使用过程中，键帽12易被触及按压。弹性件14抵接于中轴13和壳体组件11之间，具体的，弹性件14与壳体组件11靠近基板40的一端内壁抵接。弹性件14可配置成推动中轴13向远离基板40的方向移动，即远 离感应机构20的方向移动，以使中轴13复位。
使用中，可通过按压键帽12，以推动中轴13向靠近感应机构20的方向移动，进而由中轴13触发感应机构20。在此过程中弹性件14被压缩，并存储弹性势能。当键帽12不受按压作用时，在弹性件14的作用下，可使键帽12和中轴13向远离基板40的方向移动，以进行复位，由此完成一次按键操作。
如图1和图3所示，在一些具体的实施例中，壳体组件11可包括第一壳体111和第二壳体112，第一壳体111和第二壳体112内部均为中空结构。第一壳体111罩设于第二壳体112上，且在第一壳体111和第二壳体112之间形成安装腔室，中轴13和弹性件14可安装于该安装腔室中。
在一些具体的实施例中，第一壳体111与第二壳体112可拆卸连接，方便按键结构的组装，同时也便于对壳体组件11内的结构进行更换及检修，由此也可以降低维修成本。具体的，第一壳体111靠近第二壳体112的一端设置有第一卡合部1111，第二壳体112靠近第一壳体111的一端设置有第二卡合部1122。第二卡合部1122与第一卡合部1111卡合连接，以实现第一壳体111和第二壳体112的可拆卸连接。
在一些具体的实施例中，第一卡合部1111可为开设于第一壳体111侧壁上的卡合槽结构。第二卡合部1122可为设置于第二壳体112侧壁上的卡勾，且第二卡合部1122设置于第二壳体112的外侧壁。当第一壳体111罩设于第二壳体112上时，第二卡合部1122可卡接入第一卡合部1111中。
在另一些实施例中，第一卡合部1111也可为凸出设置于第一壳体111内壁上的卡勾。第二卡合部1122也可为开设于第二壳体112侧壁上卡槽结构。在第一壳体111罩设于第二壳体112上时，第一卡合部1111可卡接入第二卡合部1122中。
在另一些实施例中，第一壳体111和第二壳体112之间还可通过螺接、螺栓连接等方式实现可拆卸连接。
再一并结合图4所示，进一步的，第一壳体111靠近第二壳体112的一侧设置有若干个第一定位部1112，第二壳体112靠近第一壳体111的一侧设置有若干个第二定位部1124。第一定位部1112和第二定位部1124的数量可相等。第一定位部1112与第二定位部1124配合连接，以对第一壳体111和第二壳体112的连接起到定位作用。
在一些具体的实施例中，第一定位部1112可以是设置于第一壳体111侧壁上的定位槽。第二定位部1124可以是设置于第二壳体112端面上的定位柱。在第一壳体111与第二壳体112连接时，第二定位部1124可插合连接于第一定位部1112中。实施例中，第一定位部1112和第二定位部1124的数量均可设置成一个、两个、三个或五个等，在此不作具体限制。
如图1、图3和图5所示，键帽12可安装于第一壳体111远离第二壳体112的一端。相应的，第一壳体111远离第二壳体112的一端开设有通孔1113，以便于键帽12远离中轴13的一端可凸出于第一壳体111的端面。在一些具体的实施例中，键帽12远离中轴13的一端可设置有半球形的凸部122，凸部122相对于第一壳体111的端面凸出设置。键帽12远离凸部122的一端限位于第一壳体111内，以免键帽12脱离第一壳体111。
结合图3和图6所示，中轴13的一端可与键帽12固定连接，且中轴13可与键帽12同轴设置。在键帽12受到按压时，可将按压力传递至中轴13，进而推动中轴13移动。中轴13的另一端可从第二壳体112远离第一壳体111的一端伸出。第二壳体112的底部开设有与中轴13对应的过孔，以便于中轴13伸出第二壳体112。可以理解的是，第二壳体112的底部可为，第二壳体112中远离第一壳体111的一端壁。
在一些具体的实施例中，中轴13包括连接部131、触发部132和抵接部133。其中，抵接部133连接于连接部131和触发部132之间，且连接部131、触发部132和抵接部133同轴设置。连接部131可为柱状结构，其远离抵接部133的一端与键帽12固定连接。触发部132也可为柱状结构，并可相对于第二壳体112伸缩，当触发部132相对于第二壳体112伸出，并延伸至基板40靠近感应机构20的一侧时，触发部132可触发感应机构20。
在一些具体的实施例中，连接部131和触发部132均为圆柱状。抵接部133的外直径大于连接部131的外直径以及触发部132的外直径。弹性件14环绕触发部132设置，且弹性件14可抵接于抵接部133与第二壳体112的底部之间，弹性件14处于压缩状态。在弹性件14的作用下，可推动中轴13向远离基板40的方向移动，进而使触发部132远离感应机构20。同时，也可使键帽12凸出于第一壳体111，以便于进行下一次按键操作。
在一些具体的实施例中，抵接部133靠近第二壳体112底部的一侧设置有环形的限位槽1331，限位槽1331可对弹性件14进行限位，避免弹性件14相对于抵接部133发生偏移，以确保弹性件14可以提供稳定可靠的弹力，以使中轴13和键帽12顺利复位。可理解的是，触发部132也可对弹性件14进行导向。
再一并结合图4所示，第二壳体112的底部还设置有限位凸缘1123，限位凸缘1123设置于第二壳体112的内部。限位凸缘1123的内直径可略大于弹性件14的外直径，且限位凸缘1123与中轴13同轴。由此，限位凸缘1123可对弹性件14远离限位槽1331的一端进行限位，进一步避免弹性件14相对于中轴13发生偏移。在一些具体的实施例中，弹性件14可为弹簧。
在另一些实施例中，弹性件14还可为柔性块或弹片等结构。
另外，限位凸缘1123的内直径可大于限位槽1331的外直径，且限位凸缘1123的内直径可小于抵接部133的外直径。从而，在中轴13向靠近基板40的方向移动时，限位凸缘1123 可与抵接部133抵接，以限位中轴13的移动行程。可以理解的是，在中轴13不受按压作用力时，限位凸缘1123与抵接部133之间应留有一定的间隙，且间隙的高度应确保中轴13可移动到感应机构20位置处，以触发感应机构20。
结合图3、图4和图7所示，第二壳体112远离第一壳体111的一侧还设置有第三卡合部1121，第三卡合部1121凸出设置于第二壳体112底部的外侧，第三卡合部1121可配置成连接基板40。
实施例中，第二壳体112上设置有两第三卡合部1121，两第三卡合部1121分设于第二壳体112上过孔的两侧，且关于中轴13对称。在一些具体的实施例中，第三卡合部1121可为卡勾结构。当触发部132从第二壳体112内部伸出时，触发部132可位于两第三卡合部1121之间。
基板40上设置有供两第三卡合部1121穿过的通槽，两第三卡合部1121穿过基板40上的通槽后卡接于基板40。当然，两第三卡合部1121与基板40之间还可通过焊接进行加固，避免执行机构10相对于基板40随意晃动。
在一些具体的实施例中，感应机构20可包括发射件21和接收件22。发射件21和接收件22可焊接于基板40远离第一壳体111的一侧。实施例中，发射件21与接收件22之间的连线可与两第三卡合部1121之间的连线正交，即发射件21和接收件22对应两第三卡合部1121之间的间隙设置。当触发部132伸出第二壳体112延伸至两第三卡合部1121之间时，触发部132也可位于发射件21和接收件22之间，从而触发感应机构20。
在一些具体的实施例中，发射件21可为光发射器，接收件22可为光敏元件。在发射件21和接收件22之间无遮挡物时，接收件22可实时接收发射件21发出的光线。当触发部132位于发射件21和接收件22之间时，可进行遮挡，从而发射件21产生的光线被阻断，接收件22无法接收，进而可使接收件22发送对应感应信号。使用中，感应机构20可电连接至基板40的输入端，通过按压中轴13，可触发感应机构20产生对应感应信号并发送至基板40，即向基板40输送一输入信号。
在另外一些实施例中，感应机构20也可以包括一压敏元件，压敏元件可通过一支架夹设于两第三卡合部1121的间隙位置处，且与中轴13对应。当中轴13被按压并伸向基板40设置有感应机构20的一侧时，可由触发部132抵压压敏元件，进而触发压敏元件产生感应信号。
实施例中，将感应机构20设置于基板40远离执行机构10的一侧，一方面可以降低执行机构10的高度。另一方面，也可方便对感应机构20后期的检修及更换，当感应机构20需要进行检修或更换时，无需对执行机构10进行拆卸，从而节省感应机构20检修和更换的工序，也可降低难度。
如图8所示，在另一些实施例中，按键结构还包括有承托板30，与第二壳体112远离第一壳体111的一侧可拆卸连接。具体的，承托板30靠近第二壳体112的一侧设置有第四卡合部31，第四卡合部31与第三卡合部1121卡合连接，以实现承托板30与第二壳体112的可拆卸连接。实施例中，第三卡合部1121和第四卡合部31可为一对匹配的卡勾结构，可实现扣合连接。感应机构20可安装于承托板30靠近第二壳体112的一侧，以便于中轴13触发感应机构20。可以理解的是，当中轴13未受按压时，中轴13靠近基板40一端的端面距离承托板30之间留有一定的间隙，感应机构20可对应该部分间隙设置。在组装时，承托板30可嵌设于基板40上的通槽中，并向基板40远离执行机构10的一侧凸出，以使承托板30基本位于基板40远离执行机构10的一侧。在空间上，也可使感应机构20位于基板40远离执行机构10的一侧。承托板30与基板40之间可通过焊接等方式固定连接。当需要检修或更换感应机构20时，可将第二壳体112与承托板30分离，即可对位于承托板30上的感应机构20进行检修或更换。
如图3所示，实施例中，执行机构10还包括有吸附件15、永磁体16和电磁体17。其中，吸附件15可固定设置于中轴13远离基板40的一端。具体的，吸附件15可固定安装于键帽12内部，相应的，键帽12内部设置有容置吸附件15的容置腔121，且容置腔121的一侧边设置有开口结构，以便于吸附件15装入。实施例中，中轴13的连接部131可贯穿容置腔121，并延伸至凸部122。吸附件15可呈环状，吸附件15环绕连接部131设置，从而由连接部131对吸附件15进行限位，以避免吸附件15脱离键帽12。
永磁体16滑动设置于中轴13远离基板40的一端，具体的，永磁体16环绕连接部131设置，且位于键帽12和抵接部133之间。实施例中，抵接部133远离基板40一端端面与键帽12靠近基板40一端端面之间的距离大于永磁体16的高度，由此，永磁体16可沿着连接部131移动，靠近或远离抵接部133。在一些具体的实施例中，吸附件15可为磁性件，示例性的，吸附件15可由软磁材料制成，当永磁体16靠近时，吸附件15可被磁化，使吸附件15与永磁体16磁吸连接，当永磁体16与吸附件15分离后，吸附件15可退磁，避免阻碍永磁体16的运动。
同时，永磁体16的内直径小于抵接部133的外直径，从而可由抵接部133对永磁体16进行限位。实施例中，永磁体16的外直径可等于抵接部133的外直径。
在另一些实施例中，永磁体16的外直径也可大于或小于抵接部133的外直径。
电磁体17可固定安装于第二壳体112的内部，且靠近第二壳体112的底部一端设置。实施例中，电磁体17环绕设置于限位凸缘1123远离中轴13的一侧。电磁体17的内直径大于抵接部133的外直径及永磁体16的外直径。从而，可确保中轴13和永磁体16的顺利移动。永 磁体16可相对设置于电磁体17远离基板40的一端。
实施例中，电磁体17可为线圈。电磁体17可与感应机构20电连接。具体的，执行机构10还包括有引脚组件18，引脚组件18可配置成电连接电磁体17与感应机构20。
在一些具体的实施例中，引脚组件18包括有引脚181和安装座182，引脚181的一端固定安装于安装座182上，安装座182可固定安装于壳体组件11内部。可以理解的是，引脚181安装于安装座182的一端可与电磁体17电连接。引脚181的另一端穿过第二壳体112的底部，以延伸至壳体组件11的外部。使用中，引脚181可通过焊接的方式电连接至基板40上，感应机构20也可与基板40电连接，由此可以实现电磁体17与感应机构20的电连接。
可以理解的是，基板40上可设置有控制器，感应机构20可与基板40的输入端连接，输入端与控制器电连接，同时，引脚181也可电连接至控制器。当中轴13触发感应机构20时，可向控制器发送相应的感应信号。控制器在接收到感应信号后，可控制电磁体17通电，并通过引脚181向电磁体17传输电流。电磁体17在通电后可产生磁场，进而可驱动永磁体16运动。
具体的，在控制器控制电磁体17通电时，可使电磁体17内先流过一方向的电流，使电磁体17产生第一磁场并作用于永磁体16，以推动永磁体16向远离抵接部133的方向移动。在此过程中，永磁体16与吸附件15相吸，且对键帽12施加一抵触作用力，该抵触作用力的方向与用户施加于鼠标上的按压作用产生的作用力方向相反，该抵触作用力可通过键帽12及鼠标上盖作用至用户。
随后，控制器可调整向电磁体17供给的电流方向，以产生第二磁场并作用于永磁体16，第二磁场的方向与第一磁场的方向相反。第二磁场可驱动永磁体16与吸附件15分离，并向靠近抵接部133的方向移动，从而使永磁体16碰撞到抵接部133上，由此产生段落感。可以理解的是，电磁体17在驱动永磁体16向抵接部133运动时，第二磁场的磁场强度可满足使永磁体16与吸附件15顺利分离。
另外，实施例中还提供了一种鼠标，可用于电脑的一输入结构。其中，鼠标可包括鼠标底壳、鼠标上盖、基板40以及实施例中提供的按键结构。
实施例中，按键结构的执行机构10可设置于基板40靠近鼠标上盖的一侧，按键结构的感应机构20可设置于基板40靠近鼠标底壳的一侧。
