Description

本发明涉及键盘开关领域技术，尤其是指一种新型键盘开关。
背景技术
键盘开关，顾名思义是一种应用并安装于键盘上的开关，这种开关的主要结构包括有基座、上盖、静触片、动触片和按键，该上盖和基座围合形成容置腔，该静触片、动触片和按键设置于该容置腔中，且该按键的一端露出容置腔外，通过按压操控按键，使得按键上下活动，进而通过按键作用于动触片上，使得动触片与静触片接触连接或脱离分开，实现键盘的开启和关闭。
传统的键盘开关大多是按键内沿向下凸伸的定位柱，于基座开口作垂直伸缩，用以触发电路接点，这种键盘开关的按键定位柱与基座的接触面较小，按键在按压过程中容易发生倾斜或卡键，一方面，按键经常会出现卡滞现象，使用不顺畅、不稳定，另一方面，操作时指压触感欠佳，不能满足用户使用要求。

具体实施方式
下面将结合附图对本发明作进一步的说明。
实施例一：
如图1～4所示，分别为本发明之第一实施例的立体图、分解图、爆炸图和截面图。新型键盘开关100，包括底座10、静触片20、动触片30、上盖60、用于控制动触片30活动而与静触片20接触的按键40和用于按键40受力后复位的复位弹簧50。
上盖60扣合于底座10上，静触片20和动触片30均设置于底座10上，按键40一端可上下活动地安装于底座10上，另一端穿设上盖60，复位弹簧50的上下两端分别与按键40和底座10相抵接。

如图5～6所示，分别为本发明之第一实施例的底座和按键的结构示意图。底座10和按键40之间对称设置有用于防止按键40倾斜的第一平衡杆70和第二平衡杆80，底座10的两侧设置有第一转动槽11和第二转动槽12，按键40的两相对侧边分别设置有两个第一导滑槽41和两个第二导滑槽42；第一平衡杆70和第二平衡杆80分别可转动地嵌装于第一转动槽11和第二转动槽12中，且可转动地嵌于对应的第一导滑槽41和第二导滑槽42中并沿第一导滑槽41和第二导滑槽42来回移动。
底座10和按键40之间对称设置有用于防止按键40倾斜的第一平衡杆70和第二平衡杆80，通过两个平衡杆对按键40进行定位，使得在按压过程中，按键40不容易发生倾斜或卡键，从而保证开关100在按压过程中，操作省力、使用顺畅且指压触感好。
第一平衡杆70和第二平衡杆80对称设置在按键40两侧，当用户倾斜按压按键40时，由于按键40两侧都设置有平衡杆，通过平衡杆的转动来抵消按压力在倾斜方向的分力，进一步防止按键40倾斜或卡键，保证使用的顺畅性。
第一平衡杆70包括有第一杆体71以及两个第一延伸臂72，两个第一延伸臂72分别自第一杆体71的两端一体折弯延伸出，两个第一延伸臂72的尾端均折弯延伸出有第一 连接臂73，两个第一连接臂73彼此相对，第一杆体71可转动地嵌装于第一转动槽11中，且两个第一连接臂73分别可转动地嵌于对应的第一导滑槽41中并沿第一导滑槽41来回移动。第二平衡杆80包括有第二杆体81以及两个第二延伸臂82，两个第二延伸臂82分别自第二杆体81的两端一体折弯延伸出，两个第二延伸臂82的尾端均折弯延伸出有第二连接臂83，两个第二连接臂83彼此相对，第二杆体81可转动地嵌装于第二转动槽12中，且两个第二连接臂83分别可转动地嵌于对应的第二导滑槽42中并沿第二导滑槽42来回移动。
第一平衡杆70和第二平衡杆80均通过第一连接臂73和第二连接臂83可转动并可来回移动的安装于按键40两侧，通过第一杆体71和第二杆体81可转动的安装于底座10上，第一平衡杆70和第二平衡杆80与按键40和底座10之间的摩擦力小，在避免按键40倾斜的同时，使得按压开关100操作更加省力，进一步保证使用的顺畅性。
第一转动槽11和第二转动槽12均为并排间隔设置的两个，第一杆体71和第二杆体81的两端分别嵌于对应的第一转动槽11和第二转动槽12中。
上盖60的两相对侧面均间隔设置有两个扣齿61，底座10的两相对侧面对应于两个扣齿61之间向外凸出形成一凸起13，扣齿61能扣设于凸起13两侧，上盖60和底座10通过扣齿61和凸起13彼此扣合，二者结合紧密，避免按键40晃动，进一步防止按键40发生倾斜或卡键。
上盖60和底座10扣合形成第一容纳腔15和第二容纳腔16，静触片20和动触片30位于第一容纳腔15，按键40和复位弹簧50位于第二容纳腔16，第一平衡杆70和第二平衡杆80位于第二容纳腔16。按键40与底座10之间的接触面积小，在第一平衡杆70和第二平衡杆80保证按键40不发生倾斜的同时，按键40上下移动时摩擦力较小，操作省力。
按键40的第一导滑槽41和第二导滑槽42中间设置有一向底座10方向伸出的定位部43，底座10上对应设置有一定位孔14，通过将定位部43嵌设于定位孔14，从两侧对按键40进行定位，进一步防止按键40上下移动时发生倾斜卡键，保证使用的顺畅性。
按键40设置有导引孔44，对应地，底座10上设置有导引柱17，导引孔44套设于导引柱17外侧并沿导引柱17上下活动，通过将导引孔44套设于导引柱17外侧，从中心对按键40进行定位，保证按键40轴向运动，进一步防止按键40上下移动时发生倾斜或卡键，保证使用的顺畅性。
本发明的工作原理为：
组装过程为，首先，将静触片20和动触片30安装于底座10上，使得静触片20的第一焊接脚22和动触片30的第二焊接脚32均向下伸出底座10；其次，将复位弹簧50抵接于按键40的导引孔44下方，导引孔44可上下移动的套装于导引柱17外，同时复位弹簧50也套装于导引柱17外，复位弹簧50的下端嵌入底座10中，按键40的定位部43也可活动的嵌设于底座10的定位孔14，使得按键40一端可上下移动的设置于底座10上；然后，将第一平衡杆70和第二平衡杆80的第一连接臂73和第二连接臂83分别可转动地嵌于对应的第一导滑槽41和第二导滑槽42中，再将第一杆体71和第二杆体81可转动地嵌装于第一转动槽11和第二转动槽12中；最后，套上上盖60，使得扣齿61与凸起13扣合，上盖60安装固定于底座10上，同时按键40的另一端穿设上盖60。
防止按键40倾斜原理为：原始状态下，按键40抵住动触片30使得动触片30的动触点31与静触片20上的静触点21保持分离，此时的电路处于断开状态。
当作用力作用在按键40上时，按键40受力后从上向下运动，脱离对动触片30的抵压，动触片30在自身弹力的作用下张开而使得动触点31与静触点21接触，从而导通电路；第一平衡杆70和第二平衡杆80在按键40的作用下，第一杆体71和第二杆体81会发生转动，第一连接臂73发生转动并向右移动，第二连接臂83发生转动并向左移动。
当作用力消失时，按键40在复位弹簧50的作用下自动向上复位，使得按键40再次抵压住动触片30，动触点31与静触点21再次分离而断开电路，第一杆体71和第二杆体81逆向转动，第一连接臂73亦逆向转动并向左移动复位，第二连接臂83亦逆向转动并向右移动复位。
此按键40受力后向下运动过程中，通过两个平衡杆对按键40进行定位，使得在按压过程中，按键40不容易发生倾斜或卡键，从而保证开关100在按压过程中，操作省力、使用顺畅且指压触感好。同时，通过导引孔44套设于导引柱17外侧，从中心对按键40进行定位，通过定位部43嵌设于定位孔14，从两侧对按键40进行定位，保证按键40轴向运动，进一步防止按键40上下移动时发生倾斜或卡键，保证使用的顺畅性。
本实施例中，平衡杆设置为两个，在其它实施例中，平衡杆可大于两个。
实施例二：

本实施例的具体结构与前述第一实施例的具体结构基本相同，其所不同的是：在本实施例中，平衡杆为对称设置的两个，即第三平衡杆70a和第四平衡杆80a，第三平衡杆70a和第四平衡杆80a对称设置于上盖60和按键40外侧，上盖60的相对两边外侧分别设置有两个第三转动槽62和两个第四转动槽63，按键40的相对两侧边分别设置有两个第三导滑槽45和两个第四导滑槽46；第三平衡杆70a包括有第三杆体71a以及两个第三延伸臂72a，两个第三延伸臂72a分别自第三杆体71a的两端一体折弯延伸出，两个第三延伸臂72a的尾端均折弯延伸出有第三连接臂73a，两个第三连接臂73a彼此相对，第三杆体71a可转动地嵌装于第三转动槽62中，且两个第三连接臂73a分别可转动地嵌于对应的第三导滑槽45中并沿第三导滑槽45来回移动；第四平衡杆80a包括有第四杆体81a以及两个第四延伸臂82a，两个第四延伸臂82a分别自第四杆体81a的两端一体折弯延伸出，两个第四延伸臂82a的尾端均折弯延伸出有第四连接臂83a，两个第四连接臂83a彼此相对，第四杆体81a可转动地嵌装于第四转动槽63中，且两个第四连接臂83a分别可转动地嵌于对应的第四导滑槽46中并沿第四导滑槽46来回移动；第三转动槽62和第四转动槽63均为并排间隔设置的两个，第三杆体71a和第四杆体81a的两端分别嵌于对应的第三转动槽62和第四转动槽63中。
