技术领域
本发明涉及进行敲键操作的键开关装置，特别涉及装载在作为电子仪器的输入装置 的键盘中的键开关装置。
背景技术
在装配于笔记本电脑或掌上型计算机等便携式电子装置中的薄型， 即低高度型键盘 中， 要求进行击打操作的键开关装置的低高度化， 并且提高其操作性即手感好。 一般情 况下， 能够在低高度型键盘中使用的键开关装置设有： 支撑板 (例如， 金属薄板或键盘的 下部底板），设置在支撑板上方的键帽，相互连动以在支撑板的上方朝升降方向导引支承 键帽的一对塑料连杆部件， 对应于键帽的升降运动开闭电路的触点部的开关机构。 通过 一对塑料连杆部件相互连动， 键帽能够相对于支撑板、 朝实质上垂直方向保持规定的姿 态， 同时进行升降运动。 键开关装置的敲键操作特性会受到所述键帽的升降动作的行程 量以及伴随升降动作中所谓敲键感觉的敲键操作特性的影响。
现有笔记本型或掌上型计算机等便携式电子装置中普遍采用薄型塑料 X支撑结构装 置。 参见图 1、 图 2 (—个键帽的支撑结构装置的构成）此装置通过塑料内框连杆 4上的 塑料内框中枢轴 5与塑料外框连杆 8上的外框中枢孔铰接， 塑料外框下铰轴 9及塑料内 框下滑轴 7分别与支撑板 15上的支撑板转动部 13及支撑板滑动部 14呈转动配合、滑动 配合。塑料内框上铰轴 10及塑料外框上滑轴 6分别与键帽 1上的键帽转动部 2及键帽滑 动部 3呈转动配合、 滑动配合， 形成塑料 X支撑结构装置， 并通过呈圆拱状动作部件一 橡胶弹圈 11将键帽 1向上顶起。
参见图 1、 图 2、 图 3、 该键开关装置主要由键帽 1、 薄膜开关片 12、 支撑板 15及 各键帽 1下的由单独的塑料 X支撑结构装置、 橡胶弹圈 11等构成。 其中橡胶弹圈 11被 安装固定在薄膜开关片 12上表面并与键帽 1的内凹下表面对应， 薄膜开关片 12被安装 固定在支撑板 15的上表面， 支撑板 15上的支撑板转动部 13及支撑板滑动部 14穿过薄

确认本 膜开关片 12上的相应贯穿孔， 并位于薄膜开关片 12上表面上方附近， 由塑料外框连杆 8、塑料内框连杆 4构成的连杆支撑的下端分别与支撑板 15上的支撑板转动部 13及支撑 板滑动部 14转动、 滑动连接， 其上端分别与键帽 1上的键帽转动部 2 及键帽滑动部 3 呈转动配合、 滑动配合。
由塑料内框连杆 4、塑料外框连杆 8构成的连杆支撑材料成本、生产工艺成本较高， 同时由塑料内框连杆 4、 塑料外框连杆 8 构成的连杆支撑尺寸非常微小 （6mm X 10mm X 0. 7mm) , 要将尺寸非常微小的连杆支撑安装到支撑板 15上的支撑板转动部 13及支撑板 滑动部 14也是非常困难的工作。
连杆支撑的材料成本、 生产工艺成本及将连杆支撑安装到支撑板 15上的安装成本 居高不下是笔记本电脑键盘成本远高于传统台式电脑键盘的主要因素。 怎样高效率生产 并降低有连杆支撑的笔记本电脑键盘成本， 怎样提高笔记本电脑键盘的耐久性 （也即提 高结构纤细的塑科连杆支撑的耐久性），已成为一直困扰笔记本电脑键盘厂商至今的老大 难问题。
发明内容
本发明所要解决的第一个技术问题是提供一种制作成本低的键开关用连杆支撑。 该键开关用连杆支撑设置于支撑板与键帽之间并由两个连杆所构成，这两个连杆上 均设有使这两个连杆相互支撑并保持这两个连杆同步运动的左啮合面和右啮合面， 第一 个连杆的向下弯折的下啮合面支撑第二个连杆的向上弯折的上啮合面并与之滑动配合，第 二个连杆的向下弯折的下啮合面支撑第一个连杆的向上弯折的上啮合面并与之滑动配 合。
进一步的， 所述连杆支撑由两个对称设置的 u形连杆构成， 这两个 U形连杆的左右 两个连杆臂的末端分别向外延伸形成左啮合面和右啮合面。
进一步的，各连杆上分别设有与对应设置于键帽内侧的圆形凸台旋转滑动配合的左 右两个片弧转动部。
进一步的，各连杆的下横连接部由连杆支撑下端的横档末端的延伸面经冲压卷曲成 型的卷曲弧面构成， 卷曲弧面的外表面分别与支撑板上表面、 支撑板连接部内顶壁滑动 配合。
进一步的，各连杆的下横连接部由向上折弯的尾端圆弧面和向下弯折的前端圆弧面 构成， 尾端圆弧面与支撑板的上表面滑动配合， 前端圆弧面则与支撑板连接部的内顶壁 滑动配合。 由于上述的键开关用连杆支撑不需要将两个连杆通过铰链连接， 故结构上有所简 化， 制作成本降低。
本发明所要解决的第二个技术问题是提供一种制作成本低的键开关用连杆一体成 型支撑板结构装置。
该连杆一体成型支撑板结构装置包括橡胶弹圈、 薄膜开关片以及分别与键帽、 支撑 板连接的连杆支撑， 所述连杆支撑及支撑板上的支撑板连接部是通过在支撑板上一体冲 压形成。
进一步的， 所述支撑板与键盘尺寸相近。
或者， 所述支撑板与键帽尺寸相近。
进一步的， 在成型安装过程中处于同一板面上的支撑板与连杆支撑是通过构成工艺 连接筋的工艺左连筋和工艺右连筋刚性连接。
进一步的， 构成该该连杆支撑两个连杆上均设有使这两个连杆相互支撑并保持这两 个连杆同步运动的左啮合面和右啮合面， 第一个连杆的向下弯折的下啮合面支撑第二个 连杆的向上弯折的上啮合面并与之滑动配合，第二个连杆的向下弯折的下啮合面支撑第一 个连杆的向上弯折的上啮合面并与之滑动配合。
进一步的， 所述连杆支撑由两个对称设置的 u形连杆构成， 这两个 U形连杆的左右 两个连杆臂的末端分别向外延伸形成左啮合面和右啮合面。
进一步的， 各连杆上分别设有与对应设置于键帽内侧的圆形凸台旋转滑动配合的左 右两个片弧转动部。
进一步的， 各连杆的下横连接部由连杆支撑下端的横档末端的延伸面经冲压卷曲成 型的卷曲弧面构成， 卷曲弧面的外表面分别与支撑板上表面、 支撑板连接部内顶壁滑动 配合。
进一步的， 各连杆的下横连接部由向上折弯的尾端圆弧面和向下弯折的前端圆弧面 构成， 尾端圆弧面与支撑板的上表面滑动配合， 前端圆弧面则与支撑板连接部的内顶壁 滑动配合。
进一步的， 所述连杆支撑由两个 H形连杆构成， 左 H连杆的一根连杆臂支撑右 H连 杆的横档， 右 H连杆的一根连杆臂支撑左 H连杆的横档。
进一步的， 构成该连杆支撑的两个连杆中的其中一个连杆的左右对称的弧形支撑部 位于其左右对称的连杆臂的外侧， 另一个连杆的左右对称的弧形支撑部则位于其左右对 称的连杆连臂的内侧， 在这两个连杆的各连杆臂上均有连杆臂配合弧， 其中一个连杆上 的两个弧形支撑部分别滑动支撑住另一个连杆的两个连杆臂配合弧的下表面。
采用上述通过在支撑板上直接冲出连杆支撑以及支撑板连接部的技术手段， 不需要 再使用成本较高的注塑成型， 且整个生产工艺也有所简化， 故可降低键开关的制作成本。
本申请中所说的 "一体成型"并不限于冲压模具的使用数量， 也不限于具体的冲压 顺序。 事实上， 此处的 "一体成型"， 其确切的含义是在一块板料上冲压出不同的零件， 从而起到节省工序的目的。
因此， 在上述的 "一体成型"的结束构思之下， 本发明还可以提供另一种制作成本 低键开关用连杆一体成型支撑板结构装置。
即， 该装置包括橡胶弹圈、 薄膜开关片以及分别与键帽、 支撑板连接的连杆支撑， 所述连杆支撑是通过在连杆板的板面上批量一体冲压形成。
进一步的， 所述连杆支撑是通过在与键盘尺寸相近的连杆板的板面上批量一体冲压 形成。

进一步的， 在连杆板的板面上批量一体冲压形成的连杆支撑与支撑板上的多个或者 全部支撑板连接部形成对应关系， 安装时批量将连杆板上的连杆支撑推入支撑板上的支 撑板连接部。
后一种连杆一体成型支撑板结构装置与前一种连杆一体成型支撑板结构装置的区 别在于， 后一种连杆一体成型支撑板结构装置是将连杆支撑放到另一块与支撑板不同的 连杆板上成型， 但仍然能够大大的提高生产效率。

参见图 60、 图 61、 图 62、 图 63、 图 64， 当键帽 1被从上极限位被按下时（橡胶弹 圈 11图中未表示）， 键帽 1克服橡胶弹圈 11的弹力向下移动， 连杆支撑 17上的连杆臂 配合弧 37的下表面推动另一连杆支撑 17上的弧形支撑部 42向下移动，与此同时滑动部 上配合圆弧 50在键帽上平面 52上滑动， 滑动部下配合圆弧 51沿键帽下弧面 53滑动。
当外力去掉时键帽 1在橡胶弹圈 11的弹力作用下， 复位至上极限位。
其余与实施例 5同。
