需说明的是，当部件被称为“固定于”或“设置于”另一个部件，它可以直接在另一个部件上或者间接在该另一个部件上。当一个部件被称为是“连接于”另一个部件，它可以是直接或者间接连接至该另一个部件上。术语“上”、“下”、“左”、“右”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，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申请的限制，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的具体含义。术语“第一”、“第二”仅用于便于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明技术特征的数量。“多个”的含义是两个或两个以上，除非另有明确具体的限定。
为了说明本申请所提供的技术方案，以下结合具体附图及实施例进行详细说明。
现有键盘一般包括外壳、定位板、电路板、键帽、机械轴以及连接结构，定位板与电路板之间采用直接接触的刚性连接，定位板与电路板之间存在接触应力，在键盘打字敲击的时候，键盘的机械轴在定位板和电路板上开设的通孔内上下移动，容易使机械轴与定位板和电路板之间形成共振和空腔音，用户体验感差；另外，连接结构用于将定位板连接于外壳，定位板与外壳之间采用直接接触的刚性连接；具体地，连接结构包括第一连接件和第二连接件，第二连接件设置在外壳上，第一连接件连接穿接在定位板内，第二连接件顶接在定位板的下部，第一连接件与第二连接件连接；在键盘打字敲击的时候，由于第二连接件与定位板直接接触，键盘的机械轴在定位板和电路板上开设的通孔内上下移动，容易使定位板和第二连接件之间形成共振和空腔音，用户体验感差。
针对上述键盘使用过程中产生共振和空腔音的问题，本申请通过在电路板和定位板之间增设具有弹性的减震板，改变了定位板与外壳的刚性连接方式，并改变了电路板和定位板之间的刚性连接方式，使机械轴在定位板和电路板之间上下移动时，定位板和外壳之间以及定位板和电路板之间的受力和振动能够被减震板吸收，从而使键盘在打字敲击时噪音减小，提升用户体验感。
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。
请参阅图1和图2及图4-7所示，本申请实施例的第一目的是提供的一种减震板4，用于安装于键盘内，键盘至少包括机械轴2，减震板4具有弹性，减震板4的板面上开设有安装槽401和第二连接孔405；安装槽401的数量与机械轴2的数量一致，安装槽401用于插接机械轴2，且安装槽401的槽底部403能够用于弹性抵触于机械轴2；第二连接孔405用于连接能够固定减震板4的连接组件7，连接组件7能够与减震板4之间弹性顶接。
具体地，键盘包括多个机械轴2，机械轴2包括上盖、底座、轴芯以及弹簧等部件；上盖和底座连接，上盖和底座的内部形成腔体，轴芯位于腔体内，且轴芯的上端伸出腔体并位于上盖的上部，轴芯的下端通过弹簧与底座连接，轴芯能够通过弹簧相对于上盖和底座上下移动，轴芯上设置有动触片和静触片，动触片能够随轴芯上下移动，移动的过程中实现与静触片的连接和断开，进而实现电导通和断路，静触片的底端穿过减震板与电路板电连接；底座的底部中心设有外凸的凸起部。
其中，减震板4上开设有多个安装槽401，安装槽401的数量与第一插孔301的数量相同，且安装槽401与第一插孔301对应设置；机械轴2的下部插接于安装槽401内，安装槽401的横截面外轮廓尺寸与机械轴2下部的横截面外轮廓尺寸一致，机械轴2与安装槽401间隙配合；机械轴2的底端抵接于安装槽401的槽底部403，可见，安装槽401的槽底部403对机械轴2具有一定的承托作用，也就是说槽底部403位于机械轴2与电路板5之间，槽底部403具有弹性，槽底部403使机械轴2与电路板5之间形成弹性连接，槽底部403对机械轴2与电路板5之间起到缓冲和减震的作用，安装槽401的深度为1mm-5mm；安装槽401的槽底部403的厚度为0.5mm-3mm，轴芯的静触片的底端穿过安装槽401的槽底部403与电路板5电连接，具体地，槽底部403开设第二插孔402，轴芯的静触片的底端穿过第二插孔402与电路板5电连接；第二插孔402的外轮廓形状呈“凸”字形，也就是说，第二插孔402包括第一孔区和与第一孔区平行设置且连通的第二孔区，第一孔区和第二孔区的横截面外轮廓均呈矩形，且第一孔区的宽度小于第二孔区的宽度，第一孔区位于第二孔区宽度方向的中部。
在本实施方式中，减震板4上开设有安装槽401，使安装槽401的槽底部403能够夹设于机械轴2与电路板5之间，使机械轴2与电路板5之间弹性接触，能够进一步缓冲机械轴2底部与电路板5之间的作用力，有利于降低噪音，不易产生共振和空腔音，提升用户体验感。
再者，通过在定位板3和电路板5之间增设具有弹性的减震板4，连接组件7连接时，连接组件7能够穿设在第二连接孔405内，且连接组件7能够抵接于第二连接孔405外侧的减震板4的下表面，使连接组件7不与定位板3直接接触，连接组件7与定位板3之间弹性接触，减震板4在定位板3和连接组件之间起到缓冲的作用，使键盘使用过程中不易形成共振和空腔音，起到减震和降低噪音的作用，提升用户体验感。
在一个实施例中，参阅图4-7所示，减震板4的周向还具有环绕设置的压延部404，且压延部404的厚度小于减震板4其余位置的厚度。
在本实施方式中，压延部404的设计主要是考虑到减震板4与具有第一壳体601和第二壳体602的壳体连接的键盘结构，通过增设压延部404，能够缓冲第一壳体601和第二壳体602之间的受力，使第一壳体601和第二壳体602弹性接触连接，起到减震作用，有利于降低噪音，不易产生共振和空腔音，提升用户体验感。
请参阅图1-3所示，本申请实施例的第二目的是提供的一种键盘，键盘包括上述的减震板4，键盘还包括外壳6、键帽1、定位板3、电路板5以及连接组件7，连接组件7用于将减震板4、定位板3以及电路板5固定于外壳6，键帽1安装于机械轴2的上部，键帽1用于用户接触按压；定位板3、减震板4以及电路板5层叠设置，减震板4设置于定位板3和电路板5之间；外壳6内部设有容纳腔，定位板3和电路板5安装于容纳腔内，定位板3开设有第一插孔301，机械轴2插接于第一插孔301，定位板3上设有多个第一插孔301，第一插孔301的数量与机械轴2的数量相同，机械轴2与电路板5电连接；减震板4开设有与第一插孔301对应的安装槽401，机械轴2的下部插接于安装槽401内，安装槽401的槽底部403能够弹性抵触于机械轴2的底部，安装槽401的槽底部403用于承托机械轴2，安装槽401的槽底部403设有第二插孔402；连接组件7包括第一连接件701以及连接于外壳6的第二连接件702；第二连接件702的顶端抵接于减震板4，第一连接件701与第二连接件702连接，以与第二连接件702共同夹持定位板3、减震板4以及电路板5。
需要说明的是，为了方便描述，规定键盘正常使用状态时，键帽1所处的位置为键盘的上部，机械轴2位于键帽1的下部，定位板3位于电路板5的上部。
其中，如图9所示，电路板5上开设有多个第三插孔501，第三插孔501的数量与第一插孔301的数量相同，且第三插孔501与第一插孔301和第二插孔402对应设置，机械轴2的底座上的凸起部插接于第三插孔501。
在本实施方式中，通过在定位板3和电路板5之间增设具有弹性的减震板4，能够缓冲机械轴2在第一插孔301和安装槽401内上下移动过程中定位板3和电路板5受到的震荡力，以及能够缓冲定位板3和电路板5之间受到的作用力，使机械轴2与定位板3和电路板5之间不易形成共振，能够降低噪音，提升用户体验感；另外，通过在减震板4上开设安装槽401，使安装槽401的槽底部403能够夹设于机械轴2与电路板5之间，使机械轴2与电路板5之间弹性接触，能够进一步缓冲机械轴2底部与电路板5之间的作用力，有利于降低噪音，不易产生共振和空腔音，提升用户体验感。
再者，本键盘通过在定位板3和电路板5之间增设具有弹性的减震板4，第一连接件701和第二连接件702连接时，第二连接件702的顶端抵接于减震板4的下表面，使第二连接件702不与定位板3直接接触，第二连接件702与定位板3之间弹性接触，减震板4在定位板3和第二连接件702之间起到缓冲的作用，使键盘使用过程中不易形成共振和空腔音，起到减震和降低噪音的作用，提升用户体验感；另外，减震板4位于定位板3和电路板5之间，能够缓冲定位板3和电路板5之间的作用力，使机械轴2上下移动的过程中，机械轴与定位板3和电路板5之间以及定位板3和电路板5之间不易形成共振，能够降低噪音，提升用户体验感。
在一个实施例中，参阅图4-9所示，第一连接件701穿接于定位板3和减震板4内，第二连接件702穿接于电路板5内，且第二连接件702的伸出端与减震板4抵接，第一连接件701伸出减震板4的端部与第二连接件702的伸出端插接固定。
具体地，定位板3开设有第一连接孔302，减震板4开设有第二连接孔405，电路板5开设有第三连接孔502，第一连接孔302、第二连接孔405以及第三连接孔502分别对应设置，第一连接件701穿设于第一连接孔302和第二连接孔405内，第二连接件702穿设于第三连接孔502内，且第二连接件702的顶端抵接于减震板4的下表面，具体地，第二连接件702抵接于减震板4的第二连接孔405的孔端部，第一连接件701依次穿过第一连接孔302和第二连接孔405与第二连接件702连接，以与第二连接件702共同夹持定位板3、减震板4以及电路板5。
如图8所示，定位板3呈平板状，定位板3上设有多个第一连接孔302，第一连接孔302的数量与第一连接件701和第二连接件702的数量相同。
如图4-7所示，减震板4呈平板状，减震板4具有弹性，减震板4可以采用硅胶、TPU（热塑性聚氨酯弹性体橡胶）、TPR（热塑性橡胶材料）、泡棉等软性材料制备，减震板4可以是单片一体的结构，也可以是多片拼接而成的结构；减震板4可以是独立一体成型的，也可以将减震板4的全部或者部分减震功能部件与定位板3、底盖等键盘结构件通过双色注塑等工艺成型在一体上，以达到同样的减震效果。减震板4位于定位板3和电路板5之间，也就是说定位板3、减震板4以及电路板5顺次层叠设置，定位板3、减震板4以及电路板5的外轮廓尺寸基本一致，定位板3、减震板4以及电路板5的外轮廓形状可以为矩形、椭圆形或梯形等；减震板4上开设有多个第二连接孔405，第二连接孔405与第一连接孔302的数量一致且与第一连接孔302对应设置。

进一步地，如图12和图13所示，外壳6还可以包括与第一壳体601连接的第二壳体602，第二壳体602开设有与第一插孔301对应的第四插孔603，机械轴2插接于第四插孔603内。本键盘通过增设第二壳体602，能够对内部的定位板3、减震板4以及电路板5起到保护的作用，并能够起到较好地防尘效果。
另外，第二壳体602与定位板3可以集成设计为一个部件，参照图12和图13所示，第二壳体602即为定位板3，连接组件7将第二壳体602（定位板3）、减震板4以及电路板5连接固定于第一壳体601上。
再者，如图7和图12及图13所示，压延部404环绕于减震板4的外周，且压延部404的厚度小于减震板4主体的厚度，压延部404压接于第一壳体601和第二壳体602的之间，压延部404具有弹性。
在本实施方式中，通过增设压延部404，能够进一步缓冲第一壳体601和第二壳体602之间的受力，使第一壳体601和第二壳体602弹性接触连接，起到减震作用，有利于降低噪音，不易产生共振和空腔音，提升用户体验感。
在一个实施例中，如图5所示，减震板4的板面上还设有多个避空槽9，避空槽9为设于减震板4板面上具有一定深度的凹槽。
在本实施方式中，一部分避空槽9可用于避让LED灯或其他部件，另一部分避空槽9可用于减轻减震垫8的重量，减轻减震板4的重量有利于降低减震垫8使用过程中由于重力作用而造成的变形。
以上仅为本申请的较佳实施例而已，仅具体描述了本申请的技术原理，这些描述只是为了解释本申请的原理，不能以任何方式解释为对本申请保护范围的限制。基于此处解释，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进，及本领域的技术人员不需要付出创造性的劳动即可联想到本申请的其他具体实施方式，均应包含在本申请的保护范围之内。
