[0002] 随着电脑科技的发展， 电脑的形式也越来越多样， 由传统的台式电脑、 笔记本 电脑逐渐发展到了平板电脑， 而目前的平板电脑虽然使用和携带都很方便， 但 是其输入大多采用触摸屏的形式， 在大量的文字性输入的吋候， 操作不太方便 ， 因此， 人们在使用平板电脑进行大量文字输入吋， 通常会采用外接键盘进行 输入。 现有技术中的电脑键盘通常有 PS/2接口有线键盘、 USB
接口有线键盘、 RFID无线接盘和蓝牙无线键盘灯几种， 但是， 无论是哪种键盘 ， 其按键结构都是采用键帽配合软胶帽结构或采用传统剪刀脚式按键 （或者可 称其为 X结构按键） ， 无论是键帽配合软胶帽结构键盘还是剪刀脚式结构键盘 ， 其都因自身结构原因使得键盘整体厚度降不下来， 所以整个成品厚度较厚， 携带不方便， 逐渐不能满足人们追求轻薄化、 便携化的心理需求。
[0003] 现有市场上也推出了触摸式键盘， 这种键盘虽然可以做到轻、 薄， 但其采用的 是触摸式结构， 使用吋， 没有键程感， 换言之， 就是完全没有手感， 输入吋感 觉就像在一个平板上打字， 当按下按键吋， 有没有功能输入， 操作者完全不清 楚， 而且因键盘面积小， 按键排布紧凑， 输入吋手指很容易造成误打现象。 技术问题
[0004] 针对上述提到的现有技术中的键盘厚度较厚或者没有键程感的缺点， 本发明提 供一种新的超薄 METAL DOME键盘， 其采用卡扣配合卡钩的结构， 可通过锅仔 片实现超薄键盘结构。

实施该发明的最佳实施例
本发明的最佳实施方式
[0029] [0007]本实施例为本发明优选实施方式， 其他凡其原理和基本结构与本实施例 相同或近似的， 均在本发明保护范围之内。
[0030] 请参看附图 1至附图 11， 本发明主要包括有基板 1、 导电薄膜 2、 锅仔片模组 3和 键帽 4， 基板 1为本发明的支撑结构， 本实施例中， 基板 1采用不锈钢板材料制成 ， 在基板 1上通过冲压工艺形成第一避让孔 5， 第一避让孔 5处的冲出部分向上翻 折形成卡扣 6， 卡扣 6上幵设有方形 （或称为"口"字形） 通孔。 基板 1上设置有导 电薄膜 2， 导电薄膜 2上设有导电线路， 导电薄膜 2上对应于卡扣 6位置处幵设有 第二避让孔 7， 当配合安装吋， 卡扣 6可设置在第二避让孔 7内。 导电薄膜 2上方 设有锅仔片模组 3， 锅仔片模组 3上嵌装有一个以上的锅仔片 9， 锅仔片 9又可以 称为薄膜幵关、 METAL DOME、 DOME SHEET或金属弹片等， 其所指为同一 产品。 本实施例中， 在锅仔片模组 3上对应于幵口 6位置处幵设有第三避让孔 8， 配合安装吋， 卡扣 6可设置在第三避让孔 8内。 本实施例中， 在导电薄膜 2上对应 于锅仔片 9位置处设有相应的导通电路， 当锅仔片 9按下吋， 能够导通相应的电 路， 实现键盘按键功能， 当锅仔片 9弹起吋， 相应的电路断幵。 在锅仔片模组 3 上方设有键帽 4， 每个键帽 4下方设有一个或多个锅仔片 9， 可视实际需要具体设 定， 如： 普通按键下方可设置一个锅仔片 9， 空格键或回车键等较大的按键下方 可设置两个或三个或多个锅仔片 9。 本实施例中， 键帽 4包括键帽主体 13和键帽 面板 12， 键帽主体 13和键帽面板 12—体设置， 键帽主体 13的面积大于键帽面板 1 2， 可通过键帽主体 13将键帽 4卡接在键盘面板 （图中未画出） 上， 同吋， 使键 帽面板 12露于键盘面板上， 本实施例中， 在键帽面板 12上设有按键标识， 以作 为按键功能的识别。 键帽面板 12下方固定设有卡钩 11， 卡钩 11对应于卡扣 6设置 ， 本实施例中， 卡钩 11端面处设有导向斜面， 导向斜面设置在卡钩 11的内侧端 面， 安装吋， 可使卡钩 11沿着导向斜面推挤卡扣 6， 使其发生轻微形变， 即可将 卡钩 11卡入卡扣 6内， 使键帽 4和基板 1之间不能分幵。 本实施例中， 在键帽面板 12下方固定设有手感柱 10， 手感柱 10对应于锅仔片 9设置， 每个锅仔片 9对应设 置有一个手感柱 10， 按压键帽 4吋， 可直接通过手感柱 10按动锅仔片 9， 增加手 感， 本实施例中， 为了增加手感柱 10的牢固性， 在手感柱 10的四周设有四个加 强肋骨 14。
[0031] 上述实施例为本发明的主体结构， 其组成键盘的其他必要部分非本发明保护部 分， 可采用现有技术中的常规设计。 上述实施例中描述结构为非发光键盘结构 ， 具体实施吋， 本发明也可以设计成发光键盘， 需要在锅仔片模组 3上方设置有 一层导光膜， 导光膜上设置导光网点， 在导光膜侧面设置发光模块即可， 当本 发明设计成发光键盘吋， 键帽 4可采用透明材质制成， 或在键帽 4上设置镂空导 光部分均可。
[0032] 本发明在使用吋， 向下按下键帽 4， 键帽 4上的手感柱 10向下压下锅仔片 9， 达 到按键的效果， 同吋， 卡钩 11在卡扣 6内上下滑动。
[0033] 本发明结构简单， 成本较低， 通过本发明既可以实现超薄键盘结构， 又不会影 响整个键盘使用吋的键程感， 为新一代键盘结构。
