一种滤光片切换器
技术领域
本发明涉及影像成像领域，尤其是涉及一种滤光片切换器。 背景技术
在现有的拍摄设备中 ，为满足在黑暗的环境中拍摄的需求，拍摄设备中 都会设置有一滤光片切换器。 该滤光片切换器可以使拍摄设备进行白天拍摄 模式以及夜间拍摄模式之间的切换。 所述滤光片切换器一般包括一用于白天 拍摄模式的可见光通片以及一用于夜间拍摄模式的红外光通片。 所述滤光片 切换器一般置于拍摄设备的镜头与影像感测器之间 ，在光线充足时，该滤光 片切换器将所述可见光通片设置于所述镜头及影像感测器的光路之间 ，此时 拍摄设备可以拍摄正常的彩色图像；在光线较为昏暗时，所述滤光片切换器 切换所述红外光通片至镜头与影像感测器之间 ，此时拍摄设备可以拍摄黑白 图像。
现有滤光片切换器大多采用马达带动齿轮传动机构进行驱动，其驱动机 构复杂，组装困难，不适于各种便携式的拍摄设备。
还有少数滤光片切换器采用电磁感应的原理，在滤光片四周装上线圈， 并在相应位置固定上磁铁，利用线圈的电流通过情况来改变切换器的磁力方 向 ，来与磁铁作用。 使滤光片左右运动来改变拍摄模式，但这种滤光片切换 器，需将线圈固定在滤光片固定架四周，使产品做得很厚，增加了产品的体 积。 并且其安装麻烦，对线圈及磁铁要求高。 发明内容
本发明考虑到要使滤光片切换器做到尽可能的薄，使其能符合各种使用 场合的要求，提出了一种滤光片切换器，解决目前滤光片切换器厚度大、 安 装麻烦、 成本高的问题。

所述不可见光通片为红外光通片。
所述固定座为一根定位柱，所述磁性转子中心位置有与所述定位柱配合 的圆孔。
所述磁性转子为柱状磁铁。
所述摆动臂上有一凸柱，所述推杆上开有一横向长槽，所述凸柱套在所 述长槽内。 横向长槽的设置，使凸柱能在长槽内有一定的活动空间 ，不至于 使滤光片卡死。
所述导轨装置为位于所述底板上的凸起和位于所述滤光片侧边的导轨 槽，所述凸起套接于所述导轨槽内。 这种导轨装置的设置不会加厚滤光片， 并且结构简单。
