参阅图1，本申请提供的按键组件一实施例的结构示意图。
该按键组件包括壳体10、按键20、弹性按键帽30和触发键40。
结合参阅图2，其中，壳体10设有第一通孔11，触发键40固定于壳体10内，弹性按键帽30包括弹性连接的中心体31和外连接体32，中心体31用于传递按压力至触发键40，外连接体32用于与壳体10相装配，按键20安装于第一通孔11并与中心体31弹性抵接。
按键10安装于第一通孔11并与中心体31弹性抵接，即中心体31始终对按键10有一弹性力。在按键10未承受按压力时，该弹性力促使按键10与第一通孔11的相对位置保持不变，进而对按键10有预压顶紧的作用。在设置有该按键组件的设备中，可避免按键10在使用过程中因松动而发生异响。
可以理解地，按键20安装于第一通孔11，可沿第一通孔11轴向相对壳体10在一定空间内移动，以击发触发键40和回复到按键20的初始位置。按键20还通过第一通孔11与外部空间接触，例如按键20通过第一通孔凸出于壳体10， 以便于按压，或者按键20与壳体10平齐，有利于产品的美感。
具体地，按键20受按压力沿第一通孔11轴向移动，以通过中心体31传递按压力至触发键40，触发键40被击发而发出电信号。该电信号用于控制设备的某一功能，例如开启或关闭调度台等。
参阅图2，本实施例中，弹性按键帽30包括弹性连接的中心体31和外连接体32，外连接体32与中心体31彼此嵌套设置。外连接体32设有用于与壳体10卡接装配的卡槽321，外连接体32与中心体31靠近按键20的顶端一体连接。
具体地，弹性按键帽30采用弹性材料制作而成，例如硅胶、橡胶或类似性质的材料。中心体31呈柱状结构，凸出于外连接体32可与触发键40接触，传递按压力至触发键40。外连接体32呈套状结构，其套状侧壁上设置有卡槽321，卡槽321用于设置弹性按键帽30于壳体10上，或通过其他连接件设置于壳体10上。中心体31及外连接体32朝向按键20的顶端一体连接，以使中心体31经过外连接体32的中部空腔伸向触发键40。
弹性按键帽30在自然状态下，中心体31的顶端位于外连接体32所形成的空腔之外，以使按键20按压中心体31时，弹性按键帽30的这种结构设计可补偿中心体31的可移动位移量，中心体31在承受按压力时，外连接体32与中心体31间的弹性连接体可历经由压缩到拉伸的状态，进而在按压力消失，中心体31能够很好地回弹，使按键30回复到未承受按压力的预紧状态。
可选地，中心体31靠近按键20的顶端设有凹部311，用于与按键20对位配合，防止中心体31与按键20间的滑动，使得按压失效等状况发生。
可选地，结合参阅图3、图6，按键组件还包括固定支架50，固定支架50上设置有第二通孔51，第二通孔51与第一通孔11同轴心，卡槽321卡接于第二通孔51上，弹性按键帽30通过固定支架50设置于壳体10上。
在一实施方式下，触发键40设置于PCB板41上，PCB板41设置于固定支架50上。在另一实施方式下，触发键40可直接设置于壳体10上。
固定支架50包括一体结构的安装板52和支撑柱53，安装板52固定于壳体 10上，第二通孔51设置于安装板52上，支撑柱53位于固定支架53背离按键20的一侧，PCB板41固定于支撑柱53上。PCB板41上的安装孔与支撑柱53对位配合，通过螺钉将PCB板51固定于支撑柱上。支撑柱51可以沿固定支架50环形设置多个，或沿固定支架50环形设置成支撑壁。
可选地，继续结合参阅图3、图6，按键组件还包括导光组件60，导光组件60设置于第一通孔11上，且与PCB板41电连接，PCB板41控制导光组件60发光。
可选地，结合参阅图4，导光组件60包括导光板61与导光膜62，导光板61设置于第一通孔11上，按键20连接于导光板61上，以通过导光板61设置于第一通孔11内，导光膜62设置于固定支架50上且正对导光板61，导光膜62与PCB板41电连接。导光膜62通过双面胶或其他方式设置于固定支架50上，导光膜62上的电极621伸出固定支架50至壳体10内，通过连接装置622与PCB板41电连接，或连接装置622一端与PCB板41电连接，另一端设置于固定支架50上，进而透过固定支架50与导光膜62电连接。PCB板41控制导光膜62发光，导光膜62还紧贴于导光板61上，其发出的光，经导光板61传递至外侧空间，进而可标识出按键20的位置以及增加按键组件的装饰性。
具体地，参阅图5，导光板61包括一体结构的止挡板611和导向板612，止挡板上设置有第三通孔613，且第三通孔613与第一通孔11同轴心，按键20卡合于第三通孔613上。按键20未承受按压力时，按键20被弹性按键帽30预压顶紧于止挡板611上，按键20承受按压力后可在一定空间范围内沿第一通孔11轴向移动，其朝向触发键40移动到最大距离后，被止挡于止挡板611上。导向板612垂直设置于止挡板611上，止挡板611背离按键的外侧端止挡于壳体10上，固定支架50与壳体10共同限制止挡板611在第一通孔11轴向的位移，进而导向板612可沿第一通孔11伸向外部空间。
具体地，止挡板611呈环状，导向板612垂直设置于止挡板611上，且将第三通孔613包围在内，导向板612贴紧于第一通孔11内侧壁，其端部与壳体 10外侧面平齐或稍微凸出于壳体10外侧面，进而有利于其沿按键20四周显示灯光效果。按键20卡合于第三通孔11上，即按键20卡合于止挡板611上朝向按键20的内侧端，按键20还可沿导向板612在第一通孔11的轴向上的一定空间内移动。固定支架50还包括支撑壁54，导光膜62贴合于支撑壁54上，支撑壁54将止挡板611固定于壳体10上。在另一实施例中，按键组件还可不包括导光组件60，本申请对此不作限制。
按键20包括第一按键体21和第二按键体22，第一按键体21与第二按键体22连接以卡合于止挡板611上，第二按键体22与中心体31弹性抵接，按键20可相对止挡板611沿第一通孔11轴向移动，以通过弹性按键帽30击发触发键40。
具体地，第一按键体21包括一体式结构的按压部211和第一凸台部212，第二按键体22包括一体式结构的抵接部221和第二凸台部222，第一凸台部212和第二凸台部222可在第三通孔613内移动，按压部211可止挡于止挡板611上背离弹性按键帽30的一侧，抵接部221可止挡于止挡板611上朝向弹性按键帽30的一侧。第一凸台212和第二凸台222的物理尺寸大于弹性按键帽30的物理尺寸，以便于从抵接部221一侧设置螺纹孔以通过第一凸台部212、第二凸台部222连接按压部211，进而紧固件可以与弹性按键帽30错位设置，不会发生干涉。在另一实施例中，第一凸台212和第二凸台222的物理尺寸还可不大于弹性按键帽30的物理尺寸，不再赘述。
第二按键体22上朝向弹性按键帽的一侧设置有第三凸台23，第三凸台23与中心体31弹性抵接，即其与中心体31上的凹部311对位抵接。可选地，第二按键体22上紧贴第三凸台23根部的区域设置有容置槽231，容置槽231用于容置设置于中心体31周边的凸起部312，使得第三凸台222进一步被中心体31上的凹部311所限制。
参阅图6，按压按键20的中部位置，按键20在按压力的驱动下通过弹性按键帽30击发触发键40。此时，按键20朝向触发键40移动可不与导光组件60 接触。按键20至少在朝向触发键40的方向上止挡于导光组件60之前击发触发键，之后撤除按压力，按键20在弹性按键帽30的弹力作用下回弹至初始位置，即按键20在背离触发键40的方向上止挡于导光组件60。
参阅图7，按压按键20的左侧边缘，在按键20左侧向下的按压力和弹性按键帽30对按键20向上的预紧力的作用下，按键20的右下端与导光组件60形成一个支点位，使得按键20左端及按键20与弹性按键帽30接触的中心位置形成翘板受力的效果，相对于从按键20中部位置按压按键，翘板受力模型的弹力臂更长，使得在按键20边缘位置按压按键20，按键20的有效性仍然得到极大地保障。同理，按压按键20的其他边缘位置均会形成类翘板受力模型，使得按键20在边缘位置处的按压以击发触发键40的有效性得到极大地提高。
在另一实施例中，参阅图8，按键20包括一体式结构的按压部211和抵接柱24，按压部211上设置有折边2112，折边2112止挡于壳体10上的安装槽12内。壳体10为分离式结构，以便于按键20设置于壳体10上，即限制折边2112于安装槽12内。折边2112可沿第一通孔11轴向在安装槽12内移动，以便于按压部211受按压力后激发触发键40。按压部211沿第一通孔11伸出于壳体10且突出于壳体10，以方便按压操作；而壳体10较厚或按键20设置位置距弹性按键帽30较远，则设置抵接柱25，例如抵接柱25为圆柱状，抵接柱25与中心体31弹性抵接。
可选地，按键20背离弹性按键帽30的一侧设置有多个凸点26，用于防滑。
在另一实施例中，参阅图9，按键组件可根据不同的产品需求作出相应的设计更改。例如，产品壁厚较薄，可供按键组件设置的空间有限，按键20包括一体结构的按压部211和第三凸台23，同样按压部211上设有折边2112，折边2112止挡于壳体10上的安装槽12内，弹性按键帽30弹性抵接于第三凸台23上，按键20受按压力驱动弹性按键帽30击发触发键40。其中，第三凸台23同上述实施例中的第三凸台。按键20朝向外界的一面稍微凸出壳体10或与壳体10平齐，第三凸台23的设置使得按压部211与弹性按键帽之间的间距有效减小，按 键组件结构更加紧凑。
在另一实施例中，参阅图10，例如弹性按键帽30设置成块状，以卡接或粘接的方式与按键20连接，按键20在按压力的作用下推压弹性按键帽20以击发触发键40。
参阅图11，本申请提供的电子设备一实施例的结构示意图。
该电子设备100包括如上述的按键组件110。按键组件110可以用于控制开启或关闭电子设备100。可以理解地，按键组件110所控制的功能有多种，本申请不限制按键组件110用于控制的具体功能。
区别于现有技术的情况，本申请公开了一种按键组件及电子设备。该按键组件包括壳体、触发键、弹性按键帽和按键，壳体上设有第一通孔，触发键固定于壳体内，弹性按键帽包括弹性连接的中心体和外连接体，该中心体用于传递按压力至触发键，该外连接体用于与壳体相装配，按键安装于第一通孔并与中心体弹性抵接。通过在按键与触发键之间设置弹性按键帽，以预压顶紧按键于壳体上，使得按键时刻受到弹性力的作用，因而避免按键组件在随设备移动的过程中发出异响，以及在操作按键组件时拥有良好的按压手感和撤除按压力后便于按键回弹。
以上所述仅为本申请的实施例，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
