具体实施方式  
为更进一步阐述本实用新型为达到预定目的所采取的技术手段及功效，以下结合附图及较佳实施例，对本实用新型的具体实施方式详细说明。
请参照图1至图3，本实用新型实施例提供一种霍尔摇杆开关，包括一外壳1、设置于外壳1上且上端穿出外壳1上部的一摇动组件2、用于带动摇动组件2复位的一复位件3、及一PCB板4。本实施例霍尔摇杆开关还包括与摇动组件2连动的一磁铁5、及电连接于PCB板4且位于磁铁5下方的一霍尔芯片6，具体的，霍尔芯片6可以焊接在PCB板4上。由摇动组件2带动磁铁5摇动，使得磁铁5到霍尔芯片6的距离发生变化，来改变霍尔芯片6感应到的磁通量，即产生磁通量的变化，经霍尔芯片6感应磁通量的变化后转化成电压变化，从而输出不同的信号，实现不同的增减量功能。具体的，在摇动组件2归中的静止状态下，霍尔芯片6感知并以此为参照点，在磁铁5随着摆动之后，磁铁5与霍尔芯片6的距离发生变化，磁铁5产生了磁通量的强弱变化后，霍尔芯片6感知后转化成电压的变量输出信号。
在本实施例中，磁铁5的形状与尺寸可以根据具体情况设定，需要满足磁通量大于200GS为基准。磁铁5采用圆柱状，直径为2.0mm，高度为3.5 mm以上。对于磁铁5与霍尔芯片6之间的静态距离范围为1.2mm以下。
在本实施例中，如图2与图3所示，所述摇动组件2包括活动设置于外壳1上的一支架21、设置于外壳1内的一活动圆盘23、及设置于活动圆盘23上且与支架21活动连接的一摇杆22，该摇杆22上端穿出外壳供客户套旋钮，其中，所述磁铁5设置于摇动组件2下端，所述复位件3设置于摇杆22与活动圆盘23之间，由复位件3为摇杆22与活动圆盘23的摇动提供恢复力，使得每次摇动之后，摇杆22与活动圆盘23都能恢复至初始状态。在摇动摇杆22时，带动磁铁5 同步摇动，霍尔芯片6感应到磁通量的变化后转化为电压的变化，通过PCB板4上的6个连接端子40进行信号输出。
具体的，磁铁5的上部是N极，下部是S极。磁铁5周围的磁感线从N极出来进入S极，磁感线从N极出来后，会有部分磁感线穿透霍尔芯片6之后，再进入S极，穿透霍尔芯片6的磁感线就会被霍尔芯片6感应出来。当摇杆22带动磁铁5往不同的方向并以不同的角度摇动时，都会改变穿透霍尔芯片6的磁感线数量，磁感线数量发生改变，霍尔芯片6感应到的磁通量就会发生改变，由此霍尔芯片6即可输出不同的信号，产生不同的电压值变化，定义出不同的开关功能，例如，定义为菜单选择、音量调节、方向选择等等。
本实施例由具有特殊结构设计的摇动组件2与复位件3相结合，可实现360°摇动摇动组件2；并结合磁铁5与霍尔芯片6的设置，由摇动组件2带动磁铁5摇动，来改变磁铁5发出的磁感线穿透霍尔芯片6的数量，即可改变霍尔芯片6感应到的磁通量，并转化成电压变化，由此霍尔芯片6可输出不同的信号，不同的信号可以做不同开关功能的定义。
本实施例霍尔芯片6为本领域常规的霍尔芯片，型号可选用KTH5701，当然也可以选用其他型号。
在本实施例中，如图2至图4、图6所示，所述摇杆22包括一摇杆座221、及设置于摇杆座221上端且穿出外壳1上端的一操作杆222，其中，在该摇杆座221底部向上形成有供活动圆盘23插入的一定位槽2211，活动圆盘23插入定位槽2211内，实现两者紧密配合进行上、下滑动，且可防止发生相互转动。活动圆盘23的设置，对摇杆22提供定位与归位作用，结合复位件3，使得摇杆22在操作完成后，能够归位到中心竖直位置，即初始状态。
对于复位件3的安装，如图3、图6与图8所示，在所述摇杆座221底部形成有环设于定位槽2211外围的一上环形限位槽2212，在所述活动圆盘23底部外围设置有一支撑底盘231，在该支撑底盘231上形成有一下环形限位槽232，所述复位件3为弹簧3'，该弹簧3'上部嵌入上环形限位槽2212内，下部嵌入下环形限位槽232内，实现对弹簧3'形变范围进行限位，使得弹簧3'只在竖直方向上发生弹性形变，即可起到上下复位作用，而不会发生横向移动，由此，可以为摇杆22的摇动提供精确的弹性恢复力，利于提高整个摇动组件2动作的精确度。
本实施例由支架21与摇杆22活动设置于外壳1内做摇摆运动，摇杆22的运动及复位由活动圆盘23与弹簧3'结合带动。摇杆22摇动时带动活动圆盘23一起滑动，当活动圆盘23摆动到极限位置时，活动圆盘23底部的圆弧面在弹簧3'的复位力作用下，对摇杠22放手后就能起到复位的作用。活动圆盘23与摇杆22底部的上下伸缩运动靠弹簧3'运行，整个复位动作非常滑顺，而且寿命比较长。
在本实施例中，在所述外壳1内底部形成有与支撑底盘231底部接触的的一环形复位筋110，具体的，环形复位筋110形成于下述底座11内底部，如图3所示。由支撑底盘231底部接触于环形复位筋110，在活动圆盘23的支撑底盘231随着摇杆22摇动时，活动圆盘23的归位产生轻微偏位，而由环形复位筋110对其进行导向修正，使得活动圆盘23归位更精确，从而提高产品的归中精度。
同时，在所述环形复位筋110内设置有一凸包1101，对摇杆22与活动圆盘23的大幅度摇摆动作起到顺滑复位的作用，可滑落复位不至于锁死，防止出现卡住现象。
如图6至图8所示，在所述定位槽2211内向下延伸设置有一插柱2215，在该插柱2215外壁与定位槽2211内壁之间设置有数个筋位22150，由该数个筋位22150隔开形成数个纵向限位槽22151，在所述活动圆盘23中部形成有供插柱2215插入的一中心孔235，在该活动圆盘23侧壁上形成有插入纵向限位槽22151内的数个纵向限位块236。由插柱2215插入中心孔235内，纵向限位块236插入纵向限位槽22151内，实现活动圆盘23与摇杆22的摇杆座221紧密且稳定的安装，两者之间不会发生旋转运动，起到限位的作用，在摇杆22摇动时，磁铁5的位置发生改变，且带动活动圆盘23进行360°旋转，放手后复位件3可让摇杆22顺畅且精确的归位。
对于述磁铁5的安装，如图3、图6与图9所示，在所述插柱2215底部向上形成有一沉台孔22152，所述磁铁5设置于沉台孔22152内。
对于支架21与摇杆22的结合，如图4至图6所示，本实施例在所述支架21上形成有供摇杆座221嵌入并活动的一活动开口211，且在该支架21相对的两端分别形成有一连接插孔212，在所述摇杆座221相对的两侧边上分别设置有插入连接插孔212内的一连接凸块2214，由连接凸块2214插入连接插孔212内，实现摇杆座221与支架21的活动连接。同时，在所述支架21相对的两端分别形成有与外壳1活动连接的一连接部213，且该支架21上的两个连接插孔212与两个连接部213正交设置，由此，实现支架21分别与外壳1和摇杆22活动连接。在往某个方向摇动摇杆22时，对支架21施加了相应的作用力，使得支架21做适应性摆动，由此，摇杆22能够实现X、Y轴上的360°摇摆。本实施例支架21不但起到支撑摇杆22的作用，还为摇杆22的摇动幅度进行限定，由此，使得摇杆22摇动更加顺畅及准确。
在本实施例中，如图1与图2所示，所述外壳1包括一底座11、及设置于底座11上的一面壳12，所述摇动组件2设置于底座11与面壳12围设而成的容置腔内，且在该面壳12上形成有供摇杆22上部穿出的一开口121。
同时，在所述面壳12上设置有一固定架8，该固定架8由上至下将面壳12与底座11固定住，完成整个产品的组装，再整体安装至相应的产品上，即可实现霍尔摇杆开关的功能。
    同时，在本实施例中，活动圆盘23与底座11内底部接触，由面壳12与固定架8相结合安装后，即可将活动圆盘23限位于底座11的环形复位筋110内。
在本实施例中，如图2与图3所示，在所述底座11上设置有电连接于PCB板4的一开关7，具体的，开关7位于支架21的连接部213下方。在摇动摇杆22时，连接部213会作用于开关7，使开关7导通，并由开关7为摇动动作提供手感。当然，也可以为开关7定义其他功能。在常态下，开关为关闭状态。
在本实施例中，如图1至图3所示，在底座11底部设置有一后盖10，所述PCB板4设置于后盖10上。同时，在该PCB板4上焊接有数根连接端子40，连接端子40的数量具体可以为6个，也可以根据需要做增减，用于连接客户端的PCB板。具体的，连接端子40插到PCB板4上面的端子孔里，然后在上端面进行焊接固定， PCB板4上面焊接好电容、电阻、霍尔芯片6后安装到底座11底部，最后盖上后盖10，插上开关7组装。
在组装时，将组装好的支架21与摇杆22的半成品里面组装上磁铁5，磁铁5安装于摇杆22位置，按压到底然后对上端进行热铆。热铆后胶料会固定挡住磁铁5，预防在工作过程中有移位或是脱落现象。然后与面壳12组装，让支架21套到面壳12上，再将弹簧3'装到摇杆22底部，如图9所示。最后，与组装好活动圆盘23、开关7、PCB板4与后盖10的底座11组装结合成一体，套上固定架8即完成组装。
