Description

一种防下陷的按键结构 技术领域
本实用新型涉及供电设备技术领域，特别是涉及一种防下陷的按键结构。
背景技术
在原有按键的结构设计中，按键开关设于PCB板上，PCB板置于机构本体上，PCB板的支点在四周，PCB板的中心底部没有支撑，当PCB板的面积大到一定尺寸时，按压按键开关时，PCB板容易发生变形进而出现下陷的风险。
实用新型内容
本实用新型要解决的是原有按键结构在按压按键开关时PCB板容易发生变形进而出现下陷的风险。
为了解决上述问题，本实用新型提供一种防下陷的按键结构，其包括自上而下依次设置的按键开关、PCB板和机构本体，所述PCB板的边缘支撑在所述机构本体的上方，所述机构本体的上表面位于所述PCB板的下方设有凸起。
作为优选方案，所述凸起位于所述按键开关的正下方。
作为优选方案，所述凸起的顶部与所述PCB板的底部之间具有间隙。
作为优选方案，所述间隙为0.1-0.4mm。
作为优选方案，所述按键开关位于所述PCB板的中间位置。
作为优选方案，所述凸起设为多个。
作为优选方案，所述凸起的顶部设有拔模斜度。
作为优选方案，所述凸起与所述机构本体一体成型。
作为优选方案，所述凸起与所述机构本体可拆卸连接。
作为优选方案，所述PCB板的边缘与所述机构本体卡接。
本实用新型所提供的一种防下陷的按键结构，在机构本体的上表面位于PCB板的下方设有凸起，该凸起对PCB板起到支撑的作用，可提高按键使用时的可靠性，PCB板不易发生变形，有效防止PCB板下陷。
附图说明
图1是本实用新型一种实施例按键结构的分解结构示意图；
图2是本实用新型一种实施例按键结构的组合结构示意图；
图3是本实用新型一种实施例的机构本体的结构示意图；
突4是本实用新型又一种实施例的机构本体的结构示意图。
其中，1、按键开关；2、PCB板；3、机构本体；31、凹陷；4、凸起。
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1所示，本实用新型一种实施例防下陷的按键结构，其包括自上而下依次设置的按键开关1、PCB板2和机构本体3，PCB板2的边缘支撑在机构本体3的上方，优选地：机构本体3的上表面与PCB板2相对的位置设有凹陷31，PCB板2的边缘支撑在该凹陷31侧壁的上方；机构本体3的上表面优选为凹陷31的内部且位于PCB板2的下方设有凸起4，该凸起4对PCB板2起到支撑的作用，可提高按键使用时的可靠性，PCB板2不易发生变形，有效防止PCB板下陷变形。
PCB板2的边缘与机构本体3的侧壁可拆卸连接，优选地，PCB板2的边缘与机构本体3的侧壁卡接，具体是可以通过卡接件进行卡接。
凸起4可位于PCB板2下方的任意位置，该凸起4可设置为一个或多个，图1、图2和图4所示为设置一个凸起4的结构，图3为设置两个凸起4的结构，凸起4的位置可以是位于按键开关1的正下方，也可以是位于PCB板2下方的其它位置，由于按键开关1是按压点，压力的受力点，因此，优选地，如图1和图2所示，凸起4位于按键开关1的正下方，由此在向下按压按键开关1时，凸起4直接对PCB板2所受到的压力产生相反的抵抗力，加强了对PCB板2的支撑作用。其中，为了方便按键的使用和安装，按键开关1位于PCB板2的中间位置，相应地，可将凸起4设于PCB板2下方的中间位置。
凸起4的顶部与PCB板2的底部应做到基本持平，为了方便加工，如图2所示，凸起4的顶部与PCB板2的底部之间具有一定的间隙L，该间隙L可避免凸起4将PCB板2顶起导致PCB板2的边缘翘起而影响按键的使用。该间隙L可为0.1-0.4mm，优选为0.2mm。凸起4可以为任意的形状，如可以是圆柱体、圆锥体、多面体或其它规则或不规则的形状。此外，为了方便脱模，凸起4的顶部设有拔模斜度。凸起4可以是如图2所示的与机构本体3 一体成型的结构，也可以是如图4所示的凸起4与机构本体3可拆卸连接的结构，其根据不同的需求进行加工。
综上，本实用新型的按键结构，在PCB板的下方设置凸起作为支撑结构，可提高按键使用的可靠性，防止PCB板下陷变形。
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。
