Description

用于键盘按键的剪刀结构
技术领域
本发明涉及一种剪刀结构，特别涉及一种用于键盘按键的剪刀结构。
背景技术
传统的键盘按键结构的传动构件为剪刀式传动构件，包括内剪和外剪，内剪上自其对称的侧边上延伸设有连接轴，外剪对应位置处设有轴孔，内剪与外剪通过轴孔藕接配合，这种传动构件的制作成本高、品质难以控制，且其组装困难、需要大量人工组装、生产效率低，而且轴孔搭配也会有间隙，导致传动结构松散。
发明内容
发明目的：本发明针对传统剪刀结构存在的成本高、品质差、难组装、易松散的问题，提供一种用于键盘按键的剪刀结构。
技术方案：本发明所述的用于键盘按键的剪刀结构，包括内剪和外剪，内剪和外剪之间通过弹性连接柱固定连接，按压按键，内剪和外剪随之下压、并带动连接柱发生弹性变形，松开按键，内剪与外剪在连接柱自身的弹性恢复力作用下回复到初始状态，实现按键的传动。
具体的，内剪、外剪均为矩形框体、且内剪位于外剪的框体内部，其中，内剪包括一对内剪底臂和一对内剪侧臂，外剪包括一对外剪底臂和一对外剪侧臂，连接柱将相邻的内剪侧臂与外剪侧臂连接固定。优选的，相邻的内剪侧臂与外剪侧臂分别与连接柱的轴向两端固定连接。
进一步的，内剪、外剪与连接柱一体连接。此时，整个剪刀结构可通过双射成型工艺制成。
其中，连接柱由弹性材料制成。该弹性材料可为塑胶或橡胶等。
有益效果：与现有技术相比，本发明的显著优点在于：(1)本发明用于键盘按键的剪刀结构，内剪与外剪通过有弹性的连接柱做连接，通过弹性材料的变形和其弹性恢复力，可实现内剪与外剪的传动，传动结构紧密，将其用于键盘按键中，可显著提高按键的质量；(2)本发明的剪刀结构可通过双射成型工艺制成，内剪和外剪由同一材料注塑成型，内外剪还可以实现双色射出，内外剪射出后，再通过另一种材料射出具有弹性的连接柱，这样可大大降低人工成本，提高生产效率，同时产品品质也可以得到有效控制。
附图说明
图1为本发明的用于键盘按键的剪刀结构的示意图。；
图2为本发明的剪刀结构中外剪的结构示意图；
图3为本发明的剪刀结构中内剪的结构示意图。
具体实施方式
下面结合附图对本发明的技术方案作进一步说明。
如图1，本发明的用于键盘按键的剪刀结构，包括内剪1和外剪2，还包括内剪1和外剪2之间、用于将内、外剪固定连接的连接柱3，该连接柱3具有弹性，其可由弹性材料制成，如塑胶或橡胶等。
内剪1、外剪2可为矩形框体、且内剪1位于外剪2的框体内部。
如图2～3，其中，内剪1包括一对内剪底臂11和一对内剪侧臂12，外剪2包括一对外剪底臂21和一对外剪侧臂22，连接柱3位于相邻的内剪侧臂12与外剪侧臂22之间，将内剪1与外剪2固定连接，如可将连接柱3的轴向两端分别与内剪侧臂12与外剪侧臂22固定。
将本发明的剪刀结构用于键盘按键中，初始状态下，内剪1与外剪2相互交叉呈一定的角度，此时连接柱23也处于不受力的状态；按压按键时，内剪1和外剪2随之下压，两者在压力作用下分别相对于连接柱3向相反方向转动，使两者之间的角度逐渐变小，连接柱3在内剪1与外剪2的牵拉下发生弹性变形；松开按键后，压力解除，连接柱3依靠自身的弹性恢复力回复初始状态、并带动内剪1与外剪2回复初始状态，整个过程实现了按键的传动。
与传统的轴孔耦接配合的剪刀结构相比，本发明的剪刀结构不设轴孔，通过连接柱3自身的变形和弹性恢复力实现传动，传动过程比较紧密，将其用于键盘按键中，可显著提高按键的传动质量；而且，内剪1与外剪2之间仅需设置具有弹性的连接柱3即可，组装难度大大降低。
内剪1、外剪2与连接柱3可一体连接。此时，本发明的剪刀结构可通过双射成型工艺制备，其中，内剪1和外剪2由同一材料注塑，连接柱3由另一种材料注塑，内、外剪还可以实现双色射出，内、外剪射出后，再射出具有弹性的连接柱，与传统工艺相比，生产过程自动化程度高，可大大降低组装成本和生产成本，提高生产效率，而且，产品品质也可以得到有效控制。
