附图说明
以下结合附图描述本实用新型的实施例,其中:
图1为本实施例的磁感应开关的结构示意图。
图2为本实施例的磁感应开关的爆炸结构示意图。
图3为本实施例的磁感应开关在另一个视角的爆炸结构示意图。
图4为本实施例的磁感应开关在定位点401时的内部结构示意图。
图5为本实施例的磁感应开关在定位点402时的内部结构示意图。
具体实施方式
以下基于附图对本实用新型的具体实施例进行进一步详细说明。应当理解的是,此处对本实用新型实施例的说明并不用于限定本实用新型的保护范围。
如图1~5所示,本实施例的磁感应开关,包括底座100、安装腔200、感应电路板300、旋转盖400和磁铁500。安装腔200设置在所述底座100中;感应电路板300设置在所述安装腔200内,设有霍尔感应元件301。
霍尔感应元件301可以感应磁铁500的移动来产生信号。磁铁500设置在旋转盖400内,所述旋转盖400转动过程中所述磁铁500相对霍尔感应元件301改变位置以使所述感应电路板300产生控制信号。
旋转盖400转动设置在所述底座100上,且在转动路径上设有两个定位点401和定位点402。两个定位点产生两个控制信号,如果需要多个控制信号,可以适当增加霍尔感应元件301的数量和定位点的数量。
底座100部分固定设置,一般带有固定的结构,本实施例中,所述底座100包括底部设有安装腔200的凸台101以及密封所述安装腔200的底盖102。为了提高密封效果,底盖102采用超声波密封实现安装。
另外,为了便于连接设备,例如控制连接双色温LED灯具,本实施例中,所述底盖102上设有外接导线600,所述外接导线600一端伸入所述安装腔200与所述感应电路板300连接,另一端设有插接件。外接导线600和底盖102则固定在一起。
为了便于制造和安装,本实施例中,所述凸台101上设有卡环103,所述旋转盖400设有与该卡环103配合的卡接件403。卡接件403为设置在所述旋转盖400内壁上的卡扣,设有两个,相对设置。
为了在定位点401和定位点402实现定位,具体的结构可以根据需要进行设计,本实施例中,为了准确控制,所述旋转盖400内设有径向向内凸出的拨块404,所述凸台101顶面的设有沿着转动路径间隔布置在所述拨块404两侧的第一挡板104和第二挡板105,所述第一挡板104和第二挡板105之间设有与所述拨块404相对布置的止回凸块106,所述拨块404与所述止回凸块106的中部抵紧配合。止回凸块106的两侧分别为定位点401和定位点402,所述拨块404越过止回凸块106的中部后,所述旋转盖400在定位点401和定位点402之间切换。
具体的,所述拨块404成V字型,尖端与所述止回凸块106抵紧配合,所述止回凸块106为圆弧型的配合表面。上述结构可以使转动更顺畅且定位稳定。
