磁轭架46包括磁轭本体462及自磁轭本体462的朝向连接臂224的一表面延伸形成的多个安装部464。磁轭本体462呈环形,多个安装部464相互间隔设置,并环绕过光孔42的中心均匀分布,即,相邻的两个安装部464形成间隙。本实施方式中,安装部464的数量是5个,5个安装部464相互间隔地环绕过光孔42的中心均匀分布。磁轭架46远离安装部464的一侧固定安装在保持架44的安装槽4426内。磁轭架46固定安装安装槽4426内时,可以是紧配合固定,也可以是螺钉连接固定、螺纹连接固定等等。磁轭架46的内环以及保持架44的内环形成过光孔42的一部分,过光孔42与通光孔226对应。磁轭架46的内环套设在底座本体222的外周上,位于底座本体222的第一端2222与第二端2224之间,并可绕着底座本体222转动。在其它一些实施方式中,磁轭架46也可以是完整的没有间隙的圆环形状。
请继续参阅图3,在一些实施方式中,磁轭架46和保持架44一体成型。在另一些实施方式中,转子组件40可以仅包括保持架44,保持架44与底座本体222相匹配,保持架44直接套设在保持架44的外周。
请结合图3、图5和图7,至少一个第二磁性单元48与至少一个第一磁性单元26成对设置,每个第一磁性单元26与对应的第二磁性单元48相对设置并组成一个磁性单元组50,每个磁性单元组50内的第一磁性单元26与第二磁性单元48相互作用产生 作用力,该作用力使得第二磁性单元48相对第一磁性单元26转动。在本实施方式中,磁性单元组50的数量包括多个,多个磁性单元组50环绕所述过光孔42的中心轴均匀分布。
第二磁性单元48的数量可以为一个或多个,当第二磁性单元48的数量为多个时,例如:2个、3个、5个、6个、9个或者更多个时,多个第二磁性单元48环绕过光孔42的中心轴均匀分布。每个第二磁性单元48包括N-1个(N大于等于2)相邻且间隔排列的第二磁性件482,例如,第二磁性件482可以有1个、2个、5个、6个、7个、8个、11个、14个、17个或者更多个。每个第二磁性单元48还对应一个安装部464及一个缺口4428,每个第二磁性单元48安装在对应的安装部464上并从对应的缺口4428露出。此时,每个安装部464在磁轭本体462周向上的宽度大于或者等于所对应的第二磁性单元48在架本体442周向上的宽度。
请参阅图7,在本实施例中,第二磁性单元48有5个,5个第二磁性单元48环绕过光孔42的中心轴均匀分布。每个第二磁性单元48包含2个相邻且间隔设置的第二磁性件482。第二磁性件482可以是磁铁,磁铁贴合在安装部464的外侧壁上,相邻磁铁的相邻端的磁极相同,例如,相邻磁铁的相邻端同为S极,或相邻磁铁的相邻端同为N极。第一磁性单元26在通电时产生的电磁场和磁铁(即,第二磁性件482)产生作用力,磁吸或者排斥磁铁,两者相互作用使得转子组件40绕着底座本体222转动。
在某些实施方式中,第一磁性件262的数量多于第二磁性件482的数量。在同一个磁性单元组50中,当两个第二磁性件482与处于一端的两个第一磁性件262产生第一作用力时,该第一作用力使得第二磁性单元482相对第一磁性单元26朝第一方向转动;当两个第二磁性件482与处于另一端的两个第一磁性件262产生第二作用力时,该第二作用力使得第二磁性单元48相对第一磁性单元26朝第二方向转动,第一方向与第二方向相反。
在某些实施方式中,所述第一磁性件262是磁铁,且第二磁性件482是线圈。此时,第一磁性件262与第二磁性件482的作用力的关系与前述类似,在此不再赘述。
请参阅3、图4和图7,叶片组件60包括多个叶片62、及设置在每个叶片62上的转轴622和导杆624。
叶片62有多个,多个叶片62环绕通孔286均匀分布。在叶片62完全开放通光孔226时,多个叶片62首尾依次相接,且相接处每个叶片62的首尾沿着通光孔226的轴向是层叠设置。叶片62可以有2个、3个、5个、6个、8个或者更多个,可以根据需要设置,只要满足与凸耳444、第二导孔2822、及连接孔2824的数量对应即可。在本实施方式中,叶片62有5个,每个叶片62对应一个第二导孔2822、一个连接孔2824、 一个第一导孔4442、一个导杆624、及一个凸耳444,每个叶片62的一端与转轴622固定,转轴622穿过连接孔2824与盖体28连接,叶片62可绕着转轴622的轴线转动。每个叶片62上的导杆624通过对应的第二导孔2822和第一导孔4442依次穿设盖体本体282及转子组件40。每个叶片62具有凹口626。多个叶片的凹口626均朝向通光孔226,当多个叶片62沿着第一方向(例如顺时针方向)旋转时,打开通光孔226/通孔286,所有叶片62的凹口626可共同形成一近似的圆孔,圆孔的直径大于或者等于通孔286的直径;当多个叶片62沿着第二方向(例如逆时针方向)旋转时,可关闭通光孔226或控制通光孔226或通孔286的大小,从而控制进光量。
在一些实施方式中,叶片组件60还包括安装板64,安装板64的一端设置有与连接孔2824对应的穿孔,转轴622的一端穿过穿孔与叶片62的一端连接,导杆624的一端安装在安装板64朝向盖体本体282的侧面上。叶片62安装在安装板背离盖体本体282的侧面上,转轴622穿过穿孔与叶片62固定连接。在一些例子中,可以通过调节安装板64和叶片62的相对位置,以调叶片62相对于通光孔226的旋合的位置。
下面将阐述叶片62转动以至少部分遮挡或至少部分地开放通孔286的具体过程:
请参阅图3及图7,在每个磁性单元组50中,以逆时针方向排列,每个第一磁性单元26中位于第一位的第一磁性件262为右第一磁性件262,位于第二位的第一磁性件262为中第一磁性件262,位于第三位的第一磁性件262为左第一磁性件262。每个第二磁性单元48中位于第一位的第二磁性件482为右第一磁性件482,位于第二位的第二磁性件482为左第一磁性件482。
在一个初始状态时,导杆624位于第二导孔2822的第一极限位置(图7所示的位置),5个叶片62将通光孔226或通孔286完全关闭。当左第一磁性件262与中第一磁性件262通电时,两个第一磁性件262(即左第一磁性件262与中第一磁性件262)与两个第二磁性件482(即左第二磁性件482与右第二磁性件482)共同产生第一作用力,具体地,可以是左第一磁性件262磁吸左第二磁性件482,中第一磁性件262磁吸中第二磁性件482,也即是说,第一作用力使得第二磁性件482逆时针转动,由于第二磁性件482固定安装在磁轭架46上,而磁轭架46固定安装在保持架44上,则第二磁性件482逆时针转动会带动保持架44也逆时针转动,即保持架44的凸耳444也逆时针转动,从而使得穿设在第一导孔4442内的导杆624可从第二导孔2822的第一极限位置移动到第二极限位置;当导杆624位于第二极限位置时,5个叶片62将通光孔226或通孔286完全开放,5个叶片62的凹口626个共同形成一近似圆孔(减少了风车效应,避免形成光斑,影响成像)。在导杆624从第一极限位置移动到第二极限位置的过程中,导杆624被凸耳444推动,并带动整个叶片62绕转轴622的轴线转动以逐渐 开放通光孔226或通孔286。当导杆624移动至第一极限位置与第二极限位置之间的位置时,通光孔226或通孔286被部分打开,或者说被部分遮挡,换句话说,可以通过控制导杆624的在第二导孔2822中的相对位置,以实现叶片62对通光孔226/通孔286通光量的控制。
在另一个初始状态时,导杆624位于第二导孔2822的第二极限位置(图7所示的位置的相对端位置),5个叶片62将通光孔226或通孔286完全开放。当右第一磁性件262与中第一磁性件262通电时,两个第一磁性件262(即右第一磁性件262与中第一磁性件262)与两个第二磁性件482(即左第二磁性件482与右第二磁性件482)共同产生第二作用力,具体地,可以是右第一磁性件262磁吸右第二磁性件482,中第一磁性件262磁吸左第二磁性件482,也即是说,第二作用力使得第二磁性件482顺时针转动,由于第二磁性件482固定安装在磁轭架46上,而磁轭架46固定安装在保持架44上,则第二磁性件482顺时针转动会带动保持架44也顺时针转动,即保持架44的凸耳444也顺时针转动,从而使得穿设在第一导孔4442内的导杆624可从第二导孔2822的第二极限位置移动到第一极限位置,当导杆624位于第一极限位置时,5个叶片62将通光孔226或通孔286完全关闭,5个叶片62的凹口626共同形成近似圆孔(减少风车效应)。在导杆624从第二极限位置移动到第一极限位置的过程中,导杆624被凸耳444推动,并带动整个叶片62绕转轴622的轴线转动以逐渐关闭通光孔226或通孔286。当导杆624移动至第一极限位置与第二极限位置之间的位置时,通光孔226或通孔286被部分遮挡,或者说被部分打开,换句话说,可以通过控制导杆624的在第二导孔2822中的相对位置,以实现叶片62对通光孔226/通孔286通光量的控制。
在上述的任意一个初始状态时,N-1个第二磁性件482可依次与N个第一磁性件262的间隔处对应。
第一作用力和第二作用力的方向相反,且第一作用力和第二作用力的大小可以相同,也可以不同,可以通过调节电流的强度实现。第一作用力和第二作用力的方向可由电流的正负极和第二磁性件482的磁极共同决定,可以通过调节通过线圈上电流的方向实现。当线圈的一端(第一端)接通电源正极,另一端(第二端)接通电源的负极时,两个第一磁性件262(即左第一磁性件262与中第一磁性件262)与两个第二磁性件482(即左第二磁性件482与右第二磁性件482)产生逆时针的作用力;当线圈的第一端接通电源负极,第二端接通电源的正极时,两个第一磁性件262(即左第一磁性件262与中第一磁性件262)与两个第二磁性件482(即左第二磁性件482与右第二磁性件482)产生顺时针的作用力。
在其它实施方式中,可以是磁性单元组50的数量不变,通过增加每个磁性单元组 50中第一磁性件262和第二磁性件482数量,来增加第一作用力和第二作用力的大小。或者,可以是通过增加磁性单元组50的数量来增加第一作用力和第二作用力的大小。亦或者是,既增加磁性单元组50的数量,又增加每个磁性单元组50中第一磁性件262和第二磁性件482数量,以增加第一作用力和第二作用力的大小。
请参阅图3和图5,在一些实施方式中,快门结构100还可包括第一垫圈82,第一垫圈82套设在底座本体222的第一端2222上,且位于转子组件40和连接臂224之间。
在一些实施方式中,快门结构100还可包括第二垫圈84,第二垫圈84套设在底座本体222的第二端2224并收容在架本体442内。具体地,底座本体222的第二端2224的端面及外侧壁共同形成供第二垫圈84安装在凹槽,第二垫圈84的内圈套设在凹槽的槽壁上,第二垫圈84的外圈与保持架44内侧面抵接。第二垫圈84的朝向连接臂224的表面至少部分与凹槽的槽底抵接,第二垫圈84朝向连接臂224的表面的其它部分与磁轭架46的远离安装部464的端面抵接。第一垫圈82和第二垫圈84可以同时设置,也可以只设置其中一个。第一垫圈82和第二垫圈84用于减小转子组件40和定子组件20之间摩擦。
请参阅图8,本申请还提供一种拍摄设备1000,拍摄设备1000包括壳体200即上述任意一实施方式的快门结构100,快门结构100与壳体200结合。拍摄设备1000可以是镜头模组、相机模组、摄像头、相机、手机、等具备拍摄功能的零部件或者终端设备。
本申请实施方式的拍摄设备1000将多个叶片62均通过转轴622转动连接在定子组件20的盖体28的远离转子组件20的一侧,且每个叶片62上的导杆624依次穿设盖体28及转子组件40,并通过转子组件40与定子组件20相互作用使得转子组件40能够相对定子组件20转动,从而带动导杆624在盖体28内运动,进而带动多个叶片62绕着转轴622转动以至少部分地遮挡或至少部分地开放通孔286,如此,快门结构100能够避免采用多连杆结构和弹簧结构,实现叶片62的开合及曝光,结构简单、紧凑。
