具体地，圆顶支撑件14为硅胶材质，即圆顶支撑件14为圆顶硅胶帽。圆顶支撑件14被键帽15按压后，能够挤压部分圆顶支撑件14朝靠近电路板12的方向运动，使部分圆顶支撑件14与电路板12接触；在解除圆顶支撑件14的按压后，圆顶支撑件14能够通过自身弹性回至初始位置，以备后续使用。
圆顶支撑件14与支撑板11通过低温包覆射出工艺一体成型。
本实施例中，支撑板11可以采用金属板。圆顶支撑件14与支撑板11成型时，先将支撑板11放入模具中，然后将液态硅胶导入模具中，使液态硅胶成型为圆顶支撑件14，并与支撑板11结合为一体结构，即制作圆顶支撑件14的同时，实现圆顶支撑件14与支撑板11的固
定。通过将圆顶支撑件14与支撑板11一体成型，减少了需再固定圆顶支撑件14与支撑板11的步骤，节省键盘1的组装时间，也保证圆顶支撑件14与支撑板11的连接稳定性。
如图3至图5所示，其中，为保证支撑板11与圆顶支撑件14稳固结合，支撑板11设有多个第一连接部112，多个第一连接部112位于连接孔111的侧壁，并沿连接孔111的周向均匀分布；圆顶支撑件14设有第二连接部141，第二连接部141包覆于多个第一连接部112的外周。
本实施例中，多个第一连接部112沿连接孔111的内侧壁均匀分布，且各第一连接部112均朝向孔中心的位置延伸，相邻第一连接部112之间设置有凹陷部。圆顶支撑件14与支撑板11结合时，第二连接部141(圆顶支撑件14的底部)覆盖各第一连接部112，并填充各凹陷部，使圆顶支撑件14与支撑板11相结合。通过设置第一连接部112，增加圆顶支撑件14与支撑板11的结合面，保证圆顶支撑件14与支撑板11稳固连接。
如图2和图3所示，由于圆顶支撑件14与支撑板11结合后，二者的连接处为密封状态，导致圆顶支撑件14在被按压过程中，导致内部的气体无法排出，为使键盘1正常工作需用力按压，影响键盘1使用手感。为此，圆顶支撑件14还设有排气孔142，排气孔142用于排出圆顶支撑件14内的气体。该排气孔142连通圆顶支撑件14的内腔与圆顶支撑件14所处的外部环境，使圆顶支撑件14被按压时，其内部的气体能够沿排气孔142排出，保证键盘1的使用手感。
或者，电路板12设有排气孔142，排气孔142用于排出圆顶支撑件14内的气体；排气孔142位于电路板12上圆顶支撑件14覆盖的区域内。该排气孔142连通圆顶支撑件14的内腔与电路板12所处的外部环境，使圆顶支撑件14被按压时，其内部的气体能够沿排气孔142排出，保证键盘1的使用手感，并延长键盘1使用寿命。
如图2和图4所示，在一种可能的设计中，圆顶支撑件14设有按压部413，按压部413与键帽15抵接，使键帽15被按压的同时，键帽15直接按压按压部413，使用户在按压键盘1的一刻即具有舒适的体验。圆顶支撑件14还设有中间部145，中间部145连接第二连接部141与按压部413，排气孔142可以设置在中间部145。
如图2和图4所示，圆顶支撑件14还设有接触部144，接触部144沿按压部413朝靠近电路板12的方向凸起；接触部144用于接触电路板12。按压键帽15，键帽15通过按压部413推动接触部144与电路板12接触，使圆顶支撑件14与电路板12上对应的线路导通，实现该键帽15对应的功能。
如图2和图4所示，支撑板11设有连接凸起113，铰链13与连接凸起113连接，并能够沿连接凸起113运动。该铰链13为剪刀脚铰链13，支撑板11设有四个连接凸起113，铰链13的四端分别与四个连接凸起113连接，且连接凸起113上设有限位部，限位部能够限制铰链13在运动过程中脱离支撑板11。该连接凸起113设置在连接孔111的外周，连接凸起113由支撑板11上裁剪，且连接凸起113的一端未完全裁断。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
