具体实施方式
下面结合附图和实施例，对本实用新型的具体实施方式作进一步详细描述。以下实施例用于说明本实用新型，但不用来限制本实用新型的范围。
如图2所示，本实用新型优选实施例的一种防卡键的按键结构，其包括外壳30、按键本体10和弹力臂20，外壳30盖合于按键本体10上，且外壳30上设有使按键本体10露出的通孔32，该通孔32与按键本体10位置相对，且二者尺寸相匹配；本实用新型的弹力臂20和按键本体10为分体式，弹力臂20包括内环结构、外环结构以及设于内环结构和外环结构之间的环形缓冲部21，内环结构设于环形缓冲部21的内侧，外环结构环形缓冲部21的外侧， 内环结构通过至少三个卡接位与按键本体10进行卡接；外环结构通过至少三个卡接位与外壳30进行卡接；当按键本体10被按压时，会通过弹力臂20把压力均匀分散，本实用新型可提高按键本体10按压时的稳定性，对于直径较小或较大的按键本体10，都没有明显的杠杆效应，由此使得按键本体10不易侧翻进而发生卡键或按键失效的问题，提高了按键的使用手感，本实施例的按键结构特别适用于直径较大的按键本体10使用。
按键本体10由硬质非金属材料制成，弹力臂20由软质弹性非金属材料制成，优选地，按键本体10由硬塑料制成，弹力臂20由软塑料或硅胶制成，由此可提高按键本体10按压时压力的分散作用，进而可进一步提高按键的使用手感。
结合图3和图4所示，内环结构包括至少三个周向布置的内安装座22，内安装座22固定连接在环形缓冲部21的内侧，每个内安装座22分别通过一个卡接位与按键本体10进行卡接。优选地，内安装座22设为均匀布置的四个，需要说明的是，还可以设置为四个以上，如五个、六个等，为了确保弹力臂20的弹性作用，优选为四个。在本实施例中，内安装座22上设有第一定位孔24，按键本体10上设有与第一定位孔24相对应的第一凸起11，第一凸起11和第一定位孔24卡接，一个第一凸起11和一个第一定位孔24相配合卡接形成一个卡接位，由此实现按键本体10和弹力臂20的卡接。此外还可以是，内安装座22上设置第一凸起，而在按键本体10上设置相对应的第一定位孔，由此同样可以通过第一凸起和第一定位孔卡接的方式实现按键本体10与弹力臂20的卡接。
结合图3和图5所示，外环结构包括至少三个周向布置的外安装座23，外安装座23固定在环形缓冲部21的外侧，每个外安装座23分别通过一个卡接位与外壳30进行卡接。优选地，外安装座23设为均匀布置的四个，需要说明的是，还可以设置为四个以上，如五个、六个等，为了确保弹力臂20的弹性作用，优选为四个。在本实施例中，外安装座23上设有第二定位孔25，外壳30上设有与第二定位孔25相对应的第二凸起31，第二凸起31与第二定位孔25卡接，一个第二凸起31与一个第二定位孔25卡接形成一个卡接位，由此实现了按键本体10和弹力臂20的卡接。此外还可以是，外安装座23上设有第二凸起31，外壳30上设置相对应的第二定位孔，由此同样可以通过第二凸起31和第二定位孔25卡接的方式实现外壳30与弹力臂20的卡接。
其中，内安装座22可以设置在环形缓冲部21内侧的任意位置，相应地，外安装座23也可以设置在环形缓冲部21外侧的任意位置，为了使得按键本体10的压力能够通过内安装座22和外安装座23更直接地分散，优选地，本实施例的内安装座22和外安装座23相对设置 在环形缓冲部21的内外两侧。
优选地，环形缓冲部21的截面为中间薄两端厚的结构，由此增大环形缓冲部21的变形范围，提高环形缓冲部21的缓冲效果，进而提高弹力臂20的弹力，增加使用时的手感。
此外，作为按键结构的另一个实施例，弹力臂20的内环结构、外环结构还可以为一体式环形结构，并在为一体式环形结构的内环结构上、外环结构上分别设置至少三个卡接位，用以分别与按键本体10、外壳30卡接。
综上，本实用新型的弹力臂20包括环形缓冲部21，该环形缓冲部21的内侧通过至少三个卡接位与按键本体10卡接，环形缓冲部21的外侧通过至少三个卡接位于外壳30卡接，环形缓冲部21在按键按压时提供缓冲的效果，由此可提高按键本体10按压时的稳定性，对于直径较小或较大的按键本体10，都没有明显的杠杆效应，由此使得按键本体10不易侧翻进而发生卡键或按键失效的问题，提高了按键的使用手感，本实施例的按键结构特别适用于直径较大的按键本体10使用。
以上所述仅是本实用新型的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本实用新型技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本实用新型的保护范围。
