技术领域
本申请涉及电子技术领域，尤其涉及一种键盘以及电子设备。
背景技术
请参考图1，图1为一种笔记本电脑打开时的示意图；图2为图1中笔记本电脑关闭时的结构示意图。
笔记本电脑包括显示屏01和键盘02，键盘02包括键盘底座022和键盘面板021，二者围合形成键盘的壳体，壳体上安装有多个按键1，按键1可以进行升降操作，可以对按键1进行按压操作，按压按键1的外力撤销后，按键1可以在弹性部(图中未示出)的弹力作用下弹出复位。如图1所示，按键1需要突出于键盘面板021一定高度，这样按键1才可以进行按压操作，如图2所示，当显示屏01与键盘面板021关合时，为避免显示屏侧100与键盘面板021接触，键盘面板021与显示屏侧100之间具有大于t高度的空间，t也即按键1突出键盘面板021的高度，为按键1的按压行程。
可见，受限于按键1的按压行程，笔记本电脑的键盘的厚度较厚，如果要减小厚度，只能减少按键1按压行程，这又会导致使用者的键盘使用体验不佳。

具体实施例
本申请实施例提供一种键盘和电子设备，电子设备例如是笔记本电脑，键盘具体为笔 记本电脑的键盘，可参照下述实施例1-3详细理解。
实施例1
请参考图3、4，图3为本申请第一实施例中按键1和驱动部2、底板3配合的爆炸图；图4为图3中按键1的按键支架12和驱动部2、底板3配合的示意图；图5为本申请第一实施例中驱动部与键盘底座30滑动配合的示意图。
本申请实施例提供一种电子设备的键盘，包括键盘底座30，图3中仅示意出键盘底座30的底板3，底板3可以是分体固定于键盘底座30，或者与键盘底座30为一体式结构。键盘还包括按键1以及弹性部13，弹性部13设置在按键1和键盘底座30之间，按压按键1时，按键1可以触发设置于键盘底座30的电路板(图中未示出)，以输出相应的信号。
具体如图3所示，按键1包括键帽11、按键支架12，按键支架12包括交叉铰接的第一支臂122和第二支臂121，此时按键支架12为剪刀结构，第一支臂122具体呈框架结构，可以是门型框架结构，也可以是环形封闭式框架结构，第二支臂121设置在第一支臂122的框架内。图3中按键支架12的第一支臂122的一端铰接在底板3，铰接的一端可定义为第一支臂122的底端，第一支臂122的另一端，即顶端，顶端和键帽11可转动并滑动连接，第二支臂121的顶端与键帽11铰接，第二支臂121的底端和键盘底座30可转动并滑动连接。两个支臂的顶端可以支撑按键1的键帽11。当两个支臂交叉角度发生变化时，第一支臂122的顶端可相对键帽11转动以及滑动，第二支臂121的底端可相对键盘底座30转动以及滑动。具体动作过程以按压按键11为例，第一支臂122的底端相对键盘底座30、第二支臂121的顶端相对键帽11会转动，以推动二者的交叉铰接位置下降并平移，从而带动第一支臂122的顶端相对键帽11转动以及滑动，带动第二支臂121的底端相对键盘底座30转动以及滑动。
弹性部13处于按键支架12和键盘底座30的底板3之间，即弹性部13可支撑按键支架12，当然，弹性部13也可以直接支撑键帽11，按键支架13起到支撑键帽11和维持按键1结构稳定性的作用，使得按键1只能进行按压操作。
为清楚描述按键的位置，定义按键的第一状态和第二状态。在第一状态下，按键未被按压，除重力作用外，按键未受到其它外力。在第二状态下，按键被完全按压下降到最低位置。可以理解，通常按键具有键程，键程为按键被按压时所移动的极限(或最大)距离。换句话说，在第一状态下，按键位于键程的起点。在第二状态下，按键位于键程的终点。
在使用时，操作者可按压键帽11使其下降而靠近键盘底座30的底板3，键帽11相应地按压第一支臂122、第二支臂121的顶端，使第一支臂122、第二支臂121绕各自的绕铰接轴线转动而下降，交叉的角度变大，交叉的夹角中线与按键1的升降方向平行，则下降过程中弹性部13也相应地被压缩，当按压键帽11的外力撤除后，按键支架12和键帽11在弹性部13的复位弹力作用下，相对键盘底座30的底板3弹出而升高，又可回复到第一状态。
需要说明的是，本申请实施例中描述按键1的“下降”，即按键1向靠近键盘底座30的方向移动，“升高”即按键1向远离键盘底座30的方向移动，相应地，“下”也是朝向键盘底座30的方向，“上”为远离键盘底座30的方向。此外，高度也是以键盘底座30为参考系，突出键盘底座30的方向为高度方向。
在本申请实施例中，键盘还包括驱动部2，驱动部2能够带动按键1下降，以靠近键盘底座30并压缩弹性部13。如图3、4所示，驱动部2包括驱动板22和第一配合件，第一配合件具体为设置于驱动板22的滑动件21，滑动件21为突出于驱动部2一侧的柱状结构，可以是圆柱结构，也可以是多棱柱结构，图3中驱动板22的两侧对称设有滑动件21，图3视角下仅示意出一侧的滑动件21。按键1的按键支架12则包括按键配合件，按键配合件具体是滑槽12a，滑槽12a可以设置在第一支臂122的外侧壁，图3中，第二支臂121的外侧壁和第一支臂122的内侧壁交叉铰接，第一支臂122远离第二支臂121的一侧侧壁为其外侧壁。驱动部2的滑动件21可以至少部分插入滑槽12a，沿滑槽12a滑动，滑动件21为圆柱结构时，能够更为顺滑地沿滑槽12a移动，不易卡滞，滑动件21为多棱柱结构可以增加与滑槽12a的接触面积，便于施力。
本实施例中，驱动部还包括第二配合件，驱动板22通过第二配合件相对键盘底座30沿第一方向移动，本申请实施例中第一方向为平行于键盘底座30的方向，即平行于键盘底座30的上表面，键盘底座30的上表面为朝向按键1的一侧表面，在电子设备的键盘水平摆放时，键盘底座30的上表面往往是水平方向，则第一方向也是水平方向，而按键1通常垂直于键盘底座30的上表面，即沿竖直方向升降，则第一方向与按键1的升降方向垂直。当然，基于人机工程设计，键盘底座30的上表面可能与水平方向具有一定夹角，则第一方向与水平方向会具有一定夹角，此时第一方向与按键1的升降方向依然垂直。但是应当理解，第一方向与键盘底座30的上表面并非必须平行，而是具有一定夹角也可以，或者第一方向平行于键盘底座30的上表面，但按键1升降方向与键盘底座30的上表面具有夹角，此类情况下，第一方向与按键1升降方向的夹角小于90度大于0度。
结合图5理解，本申请实施例中驱动板22设置的第二配合件为T型滑轨24，键盘底座30设置键盘配合件，键盘配合件为与T型滑轨24配合的T型滑槽，T型滑槽和T型滑块均沿第一方向延伸，这样可限位驱动板22相对键盘底座303沿第一方向移动。显然，T型滑槽设于驱动板22，T型滑轨24设于键盘底座30也可以。
如图6、7所示，图6为图3中按键1处于第一状态下，与驱动部2的滑动件21的位置关系示意图；图7为图6中滑动件21沿滑槽12a移动后的示意图，按键1处于第二状态。
如图6所示，在按键1未受到外力按压时，按键1处于第一状态，滑槽12a与底板3的平面具有夹角，即滑槽12a相对底板3倾斜设置，滑槽12a的延伸方向与第一支臂122的延伸方向一致，滑槽12a具有第一端12a2和第二端12a1，在第一状态下，相较于第二端12a1，滑槽12a的第一端12a2更靠近底板3，从图6中可以看出，第一端12a2低于第二端12a1，此时驱动部2的滑动件21插入滑槽12a的第一端12a2，另外，本申请实施例中，第一端12a2所在的位置也是第一支臂122和底板3铰接的位置。
如图7所示，用户在不需要使用电子设备的键盘时，可以移动驱动板22沿第一方向移动，以带动滑动件21沿滑槽12a滑动，本申请实施例中，如图6所示，驱动部2可沿键盘底座30的上表面滑动，则驱动部2及其滑动件21可以设置在较低的位置，由于滑动件21随驱动板22沿第一方向直线移动，滑动件21的移动路径相对键盘底座30的高度不变，即滑动时高度保持在滑槽12a第一端12a2的高度。而在图6状态下，滑槽12a自第一端12a2向第二端12a1高度逐渐增加，滑动件21又需要保持在一个高度移动，则必然会抵压滑槽 12a的下槽壁(即靠近底板3的槽壁)，使第一支臂122受到向下的分力，向下的分力即指向底板3的分力，从而迫使第一支臂122在图6视角下绕其铰接轴线逆时针转动下降，从而带动整个按键支架12下降并压缩弹性部13，则按键1得以下降而靠近键盘底座30，即按键1的键帽11相对键盘底座30的高度降低。
当滑动件21移动至滑槽12a的第二端12a1时，第二端12a1为封闭端，滑动件21无法继续滑动，按键1下降到位而处于最低位置，即按键1处于第二状态。可设置键盘的锁定键，锁定键按下时，其他按键1按压时不会输入任何信号，则设置驱动部2的下压行程时无需考虑是否会操作按键1，而且在按下的过程中也相应地可以同时按压锁定键，以锁定键盘。再比如，驱动部2在带动按键1下压时，驱动部2动作的本身可以设置为联动输出键盘的锁定信号，可以设置锁定信号输入端，驱动部2移动到位时触发锁定信号输入端，锁定信号输入端传输锁定信号给电子设备的控制器，则即使按键1下压接触到电路板，也无法输入信号，使处于键盘锁定状态。当然，可通过控制滑动件21的行程，控制键帽11下降的高度，比如按键1下降的最低位置并未达到第二状态的位置，则按键1未能触发键盘的电路板而输入信号，即驱动部2驱动按键1下降的高度可略小于按键1的键程。
需要重新使用按键1时，驱动部2可沿与第一方向相反的方向移动，弹性部13的弹力逐渐释放，又可带动按键1逐渐弹出，直至回复到前述的第一状态，则用户又可以对按键1进行正常的按压操作。
另外，如图6所示，第一支臂122与底板3铰接，可定义第一支臂122绕第一铰接轴线转动，在按键1处于第一状态时，驱动部2未驱动按键1下降，滑动件21插入滑槽12a第一端12a2的部分与第一铰接轴线同轴，即滑槽12a的第一端12a2也是第一支臂122的铰接端，这样，在需要使用按键1时，第一支臂122的转动不受滑动件21的干涉，第一支臂122可以绕滑动件21自由转动，从而确保按键1的正常使用。
可以理解，按键1处于第一状态时，滑动件21也不限于插入在滑槽12a中且与第一铰接轴线同轴，滑槽12a的第一端12a2也不限于处于铰接位置。比如，驱动部2的滑动件21也可以沿滑动件21的移动路径脱离滑槽12a，需要驱动按键1下降时，滑动件21逐渐滑入滑槽12a中再驱动按键1下降；再比如，滑动件21可以是伸缩结构，在需要驱动按键1下降时，控制滑动件21伸出以插入滑槽12a，按键1需要正常进行按压操作时，控制滑动件21缩回以脱离滑槽12a，这些方式都可以保证滑动件21不会干涉按键1的正常按压操作。
上述实施例中，滑槽12a的第一端12a2处于第一支臂122的铰接位置，在按键支架12处于第一状态时，第一端12a2处于第一支臂122的最低位置，滑动件21沿垂直于按键1的升降方向移动，且贴合键盘底座30的表面移动时，即在第一端12a2所处的高度平面内进行移动，当滑动件21移动到滑槽12a的第二端12a1时，第一支臂122和第二支臂121均转动下降，第一支臂122和第二支臂121平齐或接近平齐，而且两个支臂以及滑槽12a均与底板3的表面大致平齐，按键1下降到最低位置，如图7所示。
另外，驱动部2沿第一方向移动，第一方向与按键1的升降方向垂直，由于弹性部13的弹力方向与按键1的升降方向一致，则驱动部2的移动方向与弹性部13的弹力方向垂直，则按键1下降到图7中所示的第二状态后，滑槽12a和驱动部2的第一方向平行，弹性部13的弹力作用在按键支架12后，并不能通过滑槽12a分解出推动滑动件21反向移动的力， 可以进一步保证按键1能够保持在下降的位置，将按键1锁定在第二状态，应知，按键1下降到第二状态后，滑槽12a与驱动部2移动的第一方向平行并不要求理论上的完全平行，大致平行即可达到该效果。当然，为了更好地锁定按键1的位置，也可以设置相应的锁定装置，在驱动部2移动带动按键1下降到第二状态后，通过锁定装置锁定驱动部2或者锁定按键1都可以。
由此可见，本申请实施例的滑槽12a设置方式和滑动件21的移动路径使得按键1的下降幅度达到最大，能够使按键支架12最大程度地下叠至平齐状态，而且还不会干涉按键1的正常按压操作，同时也有利于保证按键1保持在下降的位置。
但显然，滑槽12a也不限于按此设置，只要滑动件21沿滑槽12a滑动时能够带动按键支架12下降即可，比如，在滑动件21滑动到滑槽12a的第二端12a1时，第一支臂122、第二支臂121与底板3依然可以具有一定夹角，滑槽12a的第一端12a2也不限于设置在铰接位置。
此外，该实施例中，滑槽12a设置于按键支架12，可知，滑槽12a设置在键帽11也可以，则滑槽12a设置在键帽11也是可行的方案，比如，滑槽12a可设置在键帽11的内侧壁。
当然，滑槽12a也可以设置在驱动部2，滑动件21设置在键帽11或者按键支架12，滑槽12a倾斜设置，按键1处于第一状态时，滑动件21插入在滑槽12a的较高位置，随着滑动件21逐渐移动，滑槽12a的槽壁和滑动件21抵触，而迫使滑动件21下降，带动整个按键1下降。但可知，滑槽12a设置在按键1，驱动部2可以尽量设置在较低的位置，利于实现按键1最大程度地下降。
如图3所示，本实施例中的滑槽12a设置在第一支臂122的外侧壁，可知，滑槽12a也可以设置在第一支臂122的内侧壁，或者设置在第二支臂121的内侧壁、外侧壁都可以，设置在第一支臂122的外侧壁，在驱动时不易受到按键支架12的干涉，驱动部2的设计更为简单。可以想到，滑槽也可以设置到第一支臂122或者第二支臂121的顶壁，顶壁即朝向键帽11的壁面，此时滑动件21会抵压滑槽的槽底壁；按键配合件也可以是设置在支臂的底壁，此时按键配合件可以是盲孔结构，滑动件21移动时抵压盲孔结构的底部孔壁，以迫使支臂下降。
进一步理解，本实施例中设置在按键1的按键配合件以滑槽12a为例，可知，按键配合件也不限于是滑槽12a结构，直接设置出斜面也可以，该斜面可以设置在支臂的侧壁或者顶壁，第一配合件可以是设置在驱动部2的推动块，推动块移动时抵压斜面以产生下压的分力，带动按键1下降同样可行，即利用斜楔原理实现驱动。可见，只要驱动部2移动时，第一配合件能够抵压按键配合件，以带动按键1下降即可，第一配合件和按键配合件的具体设置方式有多种，不再一一例举。
应当知晓，当驱动部2沿按键底座30的上表面移动时，驱动部2可处于较低的位置，且可将沿按键底座30上表面的移动转化为驱动按键1沿高度方向的移动，相较于通过驱动部2直接沿高度方向移动而带动按键1沿下降的方式，本申请实施例更有利于在有限的空间内通过机械传动带动按键1下降，且易于实现下降幅度的最大化。
需要说明的是，本申请实施例中提到驱动部2及其滑动件21沿键盘底座30的上表面 移动，如前所述，通常而言，键盘底座30的上表面与按键1的升降方向垂直，驱动部2沿该第一方向移动时，驱动部2设置的高度可以较低，以确保按键1的下降幅度最大。但如前所述，驱动部2移动的第一方向也并非必须平行于键盘底座30的上表面，与键盘底座30的上表面大致平行，或者具有一定夹角也都可以，或者是沿键盘底座30的上表面移动，但键盘底座30上表面与按键1升降方向具有一定夹角也是可行的，理论上只要与按键1的升降方向具有一定夹角，在高度下降幅度方面，就会优于直接沿升降方向带动按键1下降的方案。
请继续参考图4，键盘可以包括多个按键1，本实施例中驱动部2包括驱动板22，驱动板22的两侧设有侧板23，两侧的侧板23均设有滑动件21，驱动板22可位于相邻两个按键1之间，两个滑动件21可分别沿相邻两个按键1的滑槽12a移动，以同时驱动两个按键1下降。可知，此时按键1的两侧可分别设置滑槽12a，即第一支臂122的两侧外侧壁均设置滑槽12a，一个按键1的两侧可由两个驱动板的滑动件21分别驱动下压，下压较为可靠且受力均匀。另外，驱动板两侧的滑动件21分别插入到两个按键1的滑槽12a中，驱动板相当于限位于两个按键1之间，只能在两个按键1之间空间内沿第一方向移动，还起到一定的导向、限位作用。
请继续参考图8、9，图8为本申请第一实施例中笔记本电脑的结构示意图，笔记本电脑的显示屏侧100处于打开状态；图9为图8中笔记本电脑的显示屏侧100处于关闭状态的示意图。图8、9直观的显示出该实施例的技术效果。
如图8所示，键盘包括键盘面板，键盘面板4和键盘底座30围合形成键盘的壳体，在不需要使用按键1时，可以沿第一方向移动驱动板带动按键1下降，这样，按键1突出于键盘底座30的底板3的高度得以降低，对比图8、9理解，可降低高度t，此时，键盘的壳体和显示屏体100之间无需预留出能够容纳处于第一状态下按键1的高度空间，如图8所示，键盘面板4与下降后的按键1的键帽11可以大致平齐，即按键1的高度不高于键盘面板4的高度，此时，显示屏体100不会接触到按键1，或者二者即便触碰到但按键1并不会施力到显示屏体100，可见，本实施例中键盘的壳体的高度只要和下降到位后的按键1的高度大致相等即可，则键盘的高度可以降低，相应地，笔记本电脑的厚度也就得以进一步减少，从而满足笔记本电脑的薄性化设计需求，而且又不需要减小按键1的按压行程，保持较好的使用体验。
本实施例中驱动部2沿第一方向的移动，可以是电控，例如可设置开关，按下开关，电机可带动驱动板移动，或者当笔记本电脑的显示屏100进行关闭时，自动发出控制指令启动电机带动驱动部2移动。或者，驱动部2的移动可以和显示屏100通过传动部件联动设置，即显示屏100转动与键盘闭合时，传动部件自动带动驱动部2移动，传动部件例如是将显示屏100的转动转化为直线移动，从而拉动或推动驱动部2。再或者，驱动部2的移动也可以是人为操控，由操作人员直接推动或者拉动驱动部2移动即可，这种操作本身也较为简易。
实际上，这种设置方式不仅仅有利于笔记本电脑的厚度降低，对于单独的键盘产品而言，键盘的按键1在驱动部2带动下得以降低高度，也有利于在加工、运输过程中的叠放，节省占用空间。
实施例2
请参考图10、11，图10为本申请第二实施例中多个按键1、驱动部2以及底板3装配后的示意图；图11为图10的爆炸图；图12为图11中驱动部2的示意图；图13为图12中A部位的放大图。
在第二实施例中，键盘包括多个按键1，按键1的结构可参照第一实施例理解，不再赘述，与多个按键1对应的底板3可以分别固定在键盘底座，也可以是相互连接在一起的整体并与键盘底座固定，或者底板3也可以是键盘底座的一部分。
在本实施例中，驱动部2’包括驱动板20’，驱动板20’具有多个通孔2a’，按键1可以穿出该通孔2a’，并且该通孔2a’与按键1沿第一方向应该具有一定的间距，以不干涉驱动板20’的移动。驱动板20’移动时，能够同步带动所有的按键1下降以靠近键盘底座。
如图13所示，驱动板20’由于设置多个通孔2a’，从而形成纵横交错的孔板结构，包括多个沿横向延伸的第一板梁21’和多个沿纵向延伸的第二板梁22’，第一板梁21’和第二板梁22’正交布置，相邻两个横板21’和相邻两个纵板22’之间形成通孔2a’，这里的纵向也是驱动部2’沿键盘底座平面移动的第一方向，第一支臂122和第二支臂121也是沿纵向交叉，在纵向平面内呈X形。
另外，每个第二板梁22’设有滑动件221a’，滑动件22’的数量需要保证每个按键1的滑槽12均有相应的滑动件22’配合。如图13所示，第二板梁22’纵向的两侧均设有滑动件221a’，具体是在第二板22’的边缘沿背离底板3的方向延伸形成侧板221’，侧板221’再向相邻的按键1的滑槽12a延伸形成滑动件221a’，则第二板梁22’可贴合在键盘底座的表面移动，而滑动件221a’的高度可以略高于键盘底座，则此时图13中第二板梁22’两侧的滑动件221a’可对应于与第二板梁22’相邻的两个按键1的滑槽12a，当第二板梁22’处于驱动板2’的边缘时，第二板梁22’仅和一个按键1相邻，则第二板22’仅需设置一个滑动件221a’。
另外如图13所示，第二板梁22’的底部设有沿第一方向延伸的穿孔22a’，穿孔22a’作为驱动部2’的第二配合件。再请看图11，键盘底座配设的键盘配合件为滑杆6，滑杆6贯穿穿孔22a’，滑杆6与键盘底座固定，这样驱动板20’移动时，可以沿滑杆6滑动，从而限位驱动板20’相对键盘底座沿第一方向移动。与第一实施例设置T型滑轨和T型滑槽的原理相同，都是为了限位驱动板20’的移动。可以理解，T型滑轨24和T型滑槽，以及滑杆6和穿孔22a’，都是轨道和轨道槽的一种具体结构形式，这要能够限位驱动板20’相对键盘底座沿第一方向移动即可，对于第二配件、键盘配合件的结构不做限定。
请参考图14，图14为图11中驱动部由第一位置移动到第二位置的示意图，相应地，按键1由第一状态下降至第二状态。
图14中，左侧附图示意的键盘中按键1处于第一状态，驱动部2’处于第一位置，按键1需要下降时，推动驱动部2’移动距离d至第二位置，即移动至图14中右侧附图的位置，驱动部2’的滑动件221a’从滑槽12a的第一端12a2滑动至第二端12a1，按键1下降至第二状态。该实施例中，驱动部2’移动时可以带动所有的按键1同步下降，适用于键盘具有多个按键1的情况，可提高驱动按键1下降的效率，保障同步性。而且，本实施例中多个按键1穿出驱动部2’的通孔2a’，驱动部2’的多个滑动件221a’插入在滑槽12a中，驱动部2’的高度位置得以限定，驱动部2’可以在该高度稳定地移动，无需设置限位或者导向结构。
该实施例中驱动板20’包括多个第一板梁21’和第二板梁22’，其中，第二板梁22’用于设置滑动件221a’，而第一板梁21’是用于将多个第二板梁22’连接为一体的结构，因此，第一板梁21’并不限于设置多个，一个也可以，比如，一个第一板梁21’串接多个第二板梁22’的中部，此时形成的驱动板20’呈鱼骨状，再比如，一个第一板梁21’串接多个第二板梁22’的一端，此时形成的驱动板20’呈梳齿结构，此种情况下，相邻两个第二板梁22’之间具有至少一个按键1，按键1在两个板梁22’的间隙中进行升降操作。以上所述的第一板梁21’和第二板梁22’分体连接或者一体设置都可以。
此外，针对第一实施例，图3中驱动部2的两侧都设有滑动件21，其实也可以同时驱动两个按键1下降，在键盘的按键1数量较少的情况下，驱动部2驱动一个按键1或两个按键1下降也可以，对于笔记本电脑而言，其键盘的按键1数量一般较多，一个驱动部2’设置多个滑动件221a’更易于高效操作。
实施例3
请参考图15、16，图15为本申请第三实施例中按键1和驱动部配合的示意图，按键1处于第一状态；图16为图15中按键1下降至第二状态的示意图。
在该实施例中，按键1结构与第一实施例、第二实施例中按键1结构基本相同，只是未设置滑槽12a。驱动部不同于第一、第二实施例，本实施例中的驱动部包括控制件(图中未示出)和第一配合件51，键盘底座设有按键配合件52，第一配合件51与按键1连接，可以与按键1的按键支架12、键帽11中任一者连接，按键配合件52相对键盘底座固定，可以设置在键盘底座，比如设置在键盘底座的底板3。控制件能够控制第一配合件51、按键配合件52中至少一者产生磁力，比如，按键配合件52可以是缠绕有线圈的铁芯，控制件可以控制线圈通电，以使铁芯产生磁性，而第一配合件51可以为铁磁类结构，可以是永磁铁，也可以是铁块等。这样，当按键配合件52产生磁性后，即可与第一配合件51相互吸附而带动按键1下降以靠近键盘底座。在不需要锁定按键1时，则可以控制线圈断电，则第一配合件51在弹性部13的弹力复位作用下回复到第一状态。
该实施例中，控制件可以同时控制第一配合件51或按键配合件52产生或消除磁力，以达到同步下降或同步回复的目的。仍以上述按键配合件52为绕有线圈的铁芯为例，所有按键1对应的按键配合件52的线圈都可以串联在一条线路，则控制件控制该条线路的通断，即可控制所有按键配合件52同时断电失去磁力或者同时通电而获得磁性。
本申请实施例还提供一种电子设备，包括上述各实施例所述的键盘，电子设备可以是上述提到的笔记本电脑，具有与上述各实施例相同的技术效果，不再赘述。
本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以对本申请进行若干改进和修饰，这些改进和修饰也落入本申请权利要求的保护范围内。
