第一推杆 150设置在壳体 110中并活动地设置在安装座 130中。 第一推杆 150大致沿着 壳体 110的轴线方向 D1延伸设置。 第一推杆 150包括一个第一端和一个第二端。 第一推杆 150的第一端位于第一筒部 112中, 并与操作部 120连接; 这样, 操作部 120可驱动第一推 杆 150在壳体 110中沿着轴线方向 D1相对于安装座 130滑动。 第一推杆 150的第二端位于 第二筒部 113中。 在一实施例中, 第一推杆 150上可设有凸块 152, 与弹性元件 170的上部 (当按钮 100处于图 1所示的位置时) 接触, 用于对弹性元件 170施加作用力。
搭桥 160设置在第一推杆 150的第二端上并位于第二筒部 113中。 搭桥 160可随着第一 推杆 150—同运动。 在一实施例中, 如图 2和图 3所示, 搭桥 160包括一个本体 162、 两个 延伸部 163和一个侧壁 165。本体 162大致呈环状, 可用于安装第一推杆 150, 并可用于触发 一个两位触点模块中的常开触点接通。 两个延伸部 163大致垂直地设置在本体 162上, 可起 到导向的作用。 延伸部 163的外表面上可形成有一个导向结构 164如槽 (如图 3所示) 或凸 起; 此时, 可在第二筒部 113的内表上相应地设置凸起或槽, 以便导引搭桥 160在第二筒部 113中滑动。 侧壁 165大致垂直地设置在本体 110上并位于两个延伸部 163之间。 在一实施 例中,侧壁 165沿着本体 110的周缘设置而呈弧形。一个缺口 166形成在侧壁 165和本体 110 上; 两个凹陷部 167形成在侧壁 165的内表面并位于缺口 166的两侧, 从而使得侧壁 165上 临近缺口 166的部分成为薄壁结构以安装第二推杆 190。
弹性元件 170和垫片 180设置在第一推杆 150上并位于安装座 130与第二筒部 113的台 阶 1132之间。 在一实施例中, 弹性元件 170为套设在第一推杆 150上的弹簧; 弹性元件 170 的一端与第一推杆 150上的凸块 152接触, 另一端与垫片 180接触。 垫片 180套设在第一推 杆 150上并夹设在弹性元件 170与第二筒部 113的台阶 1132之间。
如图 2和图 3所示, 第二推杆 190包括一个基体 192和两个延伸臂 193。 基体 192大致 呈杆状, 可设在搭桥 160的缺口 166中。 两个延伸臂 193设置在基体 192的两侧, 并与搭桥 160上的两个凹陷部 167对应设置。 当基体 192位于搭桥 160的缺口 166中时, 两个延伸臂 193位于搭桥 160内部并分别与两个凹陷部 167接触, 从而将第二推杆 190滑动地设置在搭 桥 160上。 在一实施例中, 两个延伸臂 193呈弧形。
上述为本发明一实施例中按钮 100的具体结构, 下面以按钮 100用于控制一个通用两位
触点模块 (即按钮 100与通用两位触点模块形成一个开关) 实现三位置通断为例, 简要说明 按钮 100的一种使用方法。
通用两位触点模块包括一个常开触点和一个常闭触点。
当按钮 100处于图 1所示的位置时, 按钮 100处于平衡位置, 此时, 第二推杆 190的下 部与搭桥 160的本体 162接触, 第二推杆 190的上部受弹性元件 170和垫片 180作用而保持 在图 1所示的位置。 当将处于平衡位置的按钮 100用于通用两位触点模块时, 可令第二推杆 190 的底端或自由端触发通用两位触点模块的常闭触点断开, 即通用两位触点模块的常开触 点和常闭触点均处于断开状态。
按压按钮 100使得第一推杆 150在安装座 130中沿着从第一筒部 112到第二筒部 113的 方向朝向通用两位触点模块滑动; 同时, 搭桥 160也在第二筒部 113中滑动直至搭桥 160触 发通用两位触点模块的常开触点接通。 在此过程中, 第一推杆 150上的凸块 152将弹性元件 170压缩; 由于第二推杆 190的底端或自由端由通用两位触点模块的常闭触点顶住 (常闭触 点可采用弹簧结构, 弹簧的弹力可顶住第二推杆 190) 而不能运动, 因此, 通用两位触点模 块的常闭触点仍处于断开状态, 而通用两位触点模块的常开触点处于接通状态。 当按钮 100 放松后, 在弹性元件 170的恢复弹性力作用下, 第一推杆 150和搭桥 160复位到图 1所示的 位置。
当将按钮 100从图 1所示的平衡位置拉起时, 第一推杆 150在安装座 130中沿着从第二 筒部 113到第一筒部 112的方向运动; 在此过程中, 弹性元件 170被压缩, 搭桥 160可带动 第二推杆 190—同沿着从第二筒部 113到第一筒部 112的方向远离通用两位触点模块, 直至 触发通用两位触点模块的常闭触点接通。此时, 通用两位触点模块的常闭触点处于接通状态, 而通用两位触点模块的常开触点处于断开状态。
如上所述, 本发明一实施中的按钮 100可利用第一推杆 150带动搭桥 160运动以控制通 用两位触点模块的常开触点的通断, 并利用安装在搭桥 160上的第二推杆 190控制通用两位 触点模块的常闭触点的通断, 从而实现三位置通断。 相较于三位置触点模块, 通用两位触点 模块的结构简单、 成本体、 安装更换方便, 因此, 采用本发明一实施中的按钮 100的开关, 可以利用成本较低的通用两位触点模块实现三位置通断, 降低成本且安装更换方便。
综上所述, 本发明公开了一种按钮, 包括一个壳体、 一个操作部、 一个安装座、 一个第 一推杆、 一个搭桥、 一个弹性元件和一个第二推杆; 所述安装座安装在所述壳体中; 所述第 一推杆活动地设置在所述安装座中; 所述第一推杆上形成有一个凸块; 所述搭桥和所述操作 部设置在所述第一推杆的两端上; 所述第二推杆活动地设置在所述搭桥上并受所述弹性元件 作用; 所述壳体中形成有一个台阶; 所述台阶位于所述安装座与所述搭桥之间; 所述弹性元
件设置在所述第一推杆上并位于所述凸块与所述台阶之间; 所述第一推杆可在所述操作部或 所述弹性元件作用下相对于所述安装座滑动, 并带动所述搭桥和 /或所述第二推杆运动。
以上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在本发明的精神和原 则之内所作的任何修改、 等同替换和改进等, 均应包含在本发明的保护范围之内。
