Description
本发明涉及到光学成像领域,尤其涉及到光转向机构以及带有光转向机构的摄像单元及其应用。
移动电子设备的摄像性能一直是消费者和厂商的关注重点,消费者希望在移动电子设备上获得可以媲美于单反相机的摄像效果,厂商为了满足市场的需求一直在寻求如何提高移动电子设备的一摄像单元的摄像性能的方案。
目前限制了移动电子设备的所述摄像单元的一摄像性能的因素在于所述摄像单元本身的尺寸,因为移动电子设备本身提供的空间有限,同时消费者也追求轻薄化的体验,所述摄像单元需要在保持较高变焦倍率的同时保持尺寸不被增加,然而一般焦距越长,需要的摄像单元的长度也越长,为了解决这一问题,潜望式摄像模组被应用于移动电子设备。
潜望式摄像模组通过一光转向机构将光线转向,从而在降低了整个摄像模组的高度尺寸,同时整个潜望式摄像模组能够被设计有一较大的有效焦距,进而满足了消费者对于高变焦倍率的需求。
也就是说,相对于传统的长焦摄像模组,来自于拍摄像对象的光线首先通过一光转向机构,所述光转向机构通常提供了一棱镜,在光转向机构内发生反射和折射之后通过镜片之后被一感光组件接收而成像。光线被所述光转向机构如何处理较大地影响到了后续的成像效果,比如说一旦光线经过所述光转向机构之后就被大量损失,会导致整个潜望式摄像模组进光量的减小,从而使得成像质量较差,因此,如何改进所述光转向机构以提高整个潜望式摄像模组的工作性能是一个需要关注的问题。

可以理解的是,术语“一”应理解为“至少一”或“一个或多个”,即在一个实施例中,一个元件的数量可以为一个,而在另外的实施例中,该元件的数量可以为多个,术语“一”不能理解为对数量的限制。
参考附图1A,附图1B至附图4所示,是根据本发明的一较佳实施例的一移动电子设备1000被阐明。
所述移动电子设备1000包括一摄像单元1和一电子设备本体2,其中所述摄 像单元1被设置于所述电子设备本体2。所述摄像单元1能够接收来自被拍摄物体的光线从而形成图像。
所述摄像单元1包括一光转向机构10,一镜头组件20以及一感光组件30,其中光线经过所述光转向机构10后达到所述镜头组件20后被所述感光组件30接收以获得关于被拍摄物体的一光学图像。
所述光转向机构10包括一光处理元件11,一弹性支撑件12以及一转向基座13,其中所述光处理元件11通过所述弹性支撑件12被支撑于所述转向基座13。所述光处理元件11具有一入射面111,一反射面112和一出射面113,来自于被拍摄物体的光线通过所述入射面111进入所述光处理元件11,继而被所述反射面112反射,最后通过所述出射面113离开所述光转向机构10之后达到所述镜头组件20。优选地,所述光转向机构10能够使得光线在经过所述光转向机构10前后发生90度转向。可以理解的是,在所述摄像单元1被配置于所述移动电子设备1000后,所述光转向机构10,所述镜头组件20以及所述感光组件30分别被延伸所述移动电子设备1000的宽度方向设置,从而对于所述摄像单元1来说,尤其是具有较大焦距的所述摄像单元1而言,极大地减少了其在所述移动电子设备1000厚度方向的尺寸。
所述转向基座13能够被驱动地转动,并且带动所述光处理元件11和所述弹性支撑件12发生转动以改变光线在所述摄像单元1内的光路。所述弹性支撑件12具有一定的弹性,并且在随着所述转向基座13转动时发生一形变,同时具有恢复原状的趋势。所述光处理元件11被支撑于所述弹性支撑件12,换句话说,所述弹性支撑件12能够带动所述光处理元件11以及所述转向基座13复位至原来位置。
所述光转向机构10进一步包括一外壳14,其中所述外壳14被直接连接于所述镜头组件20,其中所述外壳14被设置在所述光处理元件11,所述弹性支撑件12以及所述转向基座13之外起到保护作用,也避免灰尘等污染物进入。所述弹性支撑件12的两端被分别固定地连接于所述外壳14,所述转向基座13能够在所述外壳14内并且能够相对于所述外壳14发生一定角度内的转动,所述光处理元件11能够在所述外壳14内并且能够相对于所述外壳14发生一定角度内的转动。
所述转向基座13、所述光处理元件11和所述外壳14被分别设计有一定的距 离,以提供空间给所述转向基座13和所述光处理元件11以供其发生转动。
所述转向基座13具有一斜面131,其中所述斜面131用于支撑所述弹性支撑件12,所述光处理元件11的所述反射面112和所述转向基座13的所述斜面131被相对设置,并且通过所述弹性支撑件12,所述光处理元件11的所述反射面112被支撑于所述转向基座13的所述斜面131。可以理解的是,所述转向基座13的结构和形状并不对于本发明造成限制,所述转向基座13可以是一三角柱体,也可以是一板状结构。
所述光转向机构10具有一存留空间100,其中所述存留空间100形成于所述转向基座13的所述斜面131和所述光处理元件11的所述反射面112之间。对于所述光处理元件11来说,光线首先在所述入射面111发生一折射,然后进入到所述光处理元件11内部。可选地,在所述光处理元件11的所述入射面111处可被设置有一前处理件,比如说能够过滤特定光线的镀膜或者是保护所述光处理元件11的保护层。光线进行所述光处理元件11达到所述反射面112,在所述反射面112的另一侧,由于存在所述存留空间100,因而空气介质能够进入到所述存留空间100,以使所述反射面112的一侧是光密介质,另一侧是光疏介质(此处为空气介质),使得光线从所述光密介质进入所述光密介质,部分光线在入射角达到一定角度后就可以在此发生全反射,使得部分光线被完全反射,被所述反射面112反射的光线达到所述出射面113,在所述出射面113经过一次折射后离开所述光处理元件11然后达到所述镜头组件20。
当然可以理解的是,所述存留空间100内可以是其他介质,并不一定限制于空气介质,甚至所述存留空间100处于一真空或者是接近真空的状态,只要保持所述反射面112的两侧分别处于一光密和一光疏状态,使得光线自所述光处理元件11到达所述存留空间100的过程中,所述反射面112在所述光处理元件11一侧的折射率大于在所述存留空间100一侧的折射率。
可以理解的是,所述棱镜可以是玻璃材质,也可以是树脂材质制作的。
相对于传统的光转向机构10,所述存留空间100的存在使得所述光处理元件11的所述反射面112的一侧能够存留较多的空气介质,从而有利于光线在所述反射面112发生全反射。
进一步地说,所述弹性支撑件12具有一支撑面121,其中所述支撑面121和所述光处理元件11的所述反射面112被面对面设置。所述存留空间100形成于 所述弹性支撑件12和所述光处理元件11之间。
所述支撑面121具有一支撑区域1211和一非支撑区域1212,其中所述支撑区域1211高于所述非支撑区域1212,其中所述支撑区域1211直接接触于所述光处理元件11的所述反射面112,其中所述非支撑区域1212不和所述光处理元件11的所述反射面112接触。
在本示例中,所述弹性支撑件12被设计为具有一圆环结构,更加具体地说,在所述弹性支撑件12的中间位置,所述弹性支撑件12具有一通孔1240,从而所述存留空间100能够形成于所述光处理元件11的所述反射面112和所述转向基座13的所述斜面131之间。
值得一提的是,所述支撑面121可以被设置为凹凸不平的,使得所述光处理元件11的所述反射面112和所述转向基座13之间的空间更大,能够容纳更多的空气介质,以有利于在所述光处理元件11的所述反射面112的一全反射。
所述弹性支撑件12包括一外框架122,至少一第一限位连接件123以及一内框架124,其中所述第一限位连接件123形成于所述内框架124的周围,所述第一限位连接件123的一端连接于所述内框架124,另一端连接于所述外框架122。所述外框架122被直接连接于所述光转向机构10的所述外壳14。所述光处理元件11被直接支撑于所述内框架124,所述支撑面121形成于所述内框架124。在所述光处理元件11被所述转向基座13带动而转动时,所述内框架124也随着转动,但是受到来自于所述第一限位连接件123的限制作用,因为直接被连接于所述外壳14的所述外框架122被固定地连接于所述外壳14,因此所述内框架124的转动受到了限制。换句话说,所述弹性支撑件12对于所述光处理元件11的转动起到了缓冲作用,避免所述光处理元件11在所述转向基座13带动下突然的转动。从另一方面来说,当所述光处理元件11在所述转向基座13的带动下转动到了另一个角度,所述弹性支撑件12的所述第一限位连接件123被扭转同时在所述转动基座13的驱动力减弱或者是消失以使所述光处理元件11复位时,所述内框架124能够在所述第一限位连接件123的恢复原状的转动下回复到原来的位置。
所述光转向机构10进一步包括一驱动元件15,其中所述驱动元件15能够驱动所述转向基座13转动,从而带动所述弹性支撑件12和所述光处理元件11转动,进而改变光线的传播方向。所述驱动元件15被分别设置于所述转向基座13 和所述外壳14,在通电情况下生成一磁场以驱动位于所述磁场的所述转向基座13转动。
优选地,所述第一限位连接件123被设置为中心对称地形成于所述内框架124的周围,以使所述内框架124在复位时所述第一限位连接件123能够提供一平衡的作用力。
在所述摄像单元1,所述外壳14具有一进光孔140,其中所述进光孔140形成所述光处理元件11的所述入射面111的上方,光线通过所述进光孔140后进入到所述光处理元件11,光线进入所述光处理元件11后在所述光处理元件11的所述反射面112的形成一光照区域1121,即光线照射区域。光线在所述光处理元件11的所述反射面112还具有一全反射区域1122,可以理解的是,所述全反射区域1122大部分重叠于所述光照区域1121并且所述全反射区域1122全部被所述光照区域1121所包含,但是并不是所有的所述光照区域1121都是所述全反射区域1122。因为在部分所述光照区域1121,入射角并不能达到发生全反射的条件,尤其是在所述光照区域1121的边缘区域,因此在传统的所述摄像单元1中,获得的图像边缘可能会存在偏暗的现象。
在本示例中,所述内框架124具有所述通孔1240,其中所述光处理元件11的所述全反射区域1122对应于所述通孔1240位置,以在所述全反射区域1122提供更多的空间供存留更多的空气介质以使在所述光处理元件11的所述全反射区域1122发生一较好的全反射。
进一步地,在所述通孔1240位置附近,对应于所述光照区域1121但是并不对应于所述全反射区域1122,所述内框架124被设置有一加强区域,其中所述加强区域对于光线具有较高的反射率,以使在所述光照区域1121但是并不在所述全反射区域1122的光线,也就是在所述光处理元件11的所述反射面112无法发生全反射的光线能够在所述反射面112发生折射后来到所述内框架124的所述加强区域,所述加强区域直接将光线反射回所述光处理元件11,以起到补充进光量的作用,减小最终图像边缘出现暗部的现象。
所述内框架124的所述加强区域的反射率的增强可以通过抛光或者是镀膜等工艺实现。
所述内框架124的所述通孔1240的形状可以是方形,圆形,或者是多边形。

所述光转向机构10包括所述光处理元件11,所述弹性支撑件12,所述转向基座13以及所述外壳14,其中所述光处理元件11,所述弹性支撑件12,所述转向基座13被容纳于所述外壳14,其中所述转向基座13被以可驱动的方式转动地连接于所述外壳14,其中所述光处理元件11被连接于所述转向基座13以在所述转向基座13被驱动时被所述转向基座13带动从而一起转动,所述弹性支撑件12位于所述光处理元件11和所述转向基座13之间。
所述弹性支撑件12具有一支撑面121,所述支撑面121朝向所述光处理元件11的所述反射面112,当所述光处理元件11被支撑于所述弹性支撑件12,部分所述反射面112被直接支撑于所述支撑面121。
在所述转向基座13带动所述光处理元件11转动的过程中,所述弹性支撑件12具有一定的弹性,一方面在所述弹性支撑件12和所述转向基座13中起到缓冲作用,另一方面所述弹性支撑件12随着所述转向基座13的转动发生扭转但是同时有着恢复形变的趋势,从而所述弹性支撑件12能够帮助所述光处理元件11 转动时原来的位置。
具体地说,所述弹性支撑件12包括一外框架122,至少一第一限位连接件123以及一内框架124,其中所述外框架122被直接连接于所述外壳14,所述内框架124通过所述第一限位连接件123被连接于所述外框架122,从而被支撑于所述外壳14,也就是说,在所述转向基座13带动所述弹性支撑件12转动的同时,所述弹性支撑件12的所述内框架124跟随所述转向基座13一同转动,而被直接连接于所述外壳14的所述外框架122几乎不发生转动。所述第一限位连接件123随着所述内框架124的转动发生扭转或者说形变,驱动所述转向基座13转动的作用力不仅需要克服所述转向基座13本身的重力,还需要克服来自于所述弹性支撑件12的作用力,并且在所述光处理元件11和所述转向基座13复位的过程中,所述弹性支撑件12能够提供作用力以帮助所述光处理元件11和所述转向基座13快速复位。所述支撑面121形成于所述内框架124。
所述内框架124具有一通孔1240,所述通孔1240位于所述内框架124的一中间位置,其中所述通孔1240的面积被设置为大于所述光处理元件11的所述反射面112的所述光照区域1121,以使透过所述光处理元件11的所述反射面112的光线无法被所述内框架124反射从而减少杂光对于所述摄像单元1成像质量的影响。也就是说,所述光处理元件11的所述反射面112的所述光照区域1121在所述通孔1240位置的投影面积被包含于所述通孔1240的面积。
进一步地,所述通孔1240位置附近的所述支撑面121的至少部分被涂黑或者是增大粗糙度的以减少附近杂光进入到所述光处理元件11的所述反射面112从而对于最后的成像效果造成影响。
可选地,对应于所述光照区域1121的所述转向基座13的所述斜面131至少部分被涂黑或者是粗糙度较大的,以避免所述转向基座13的所述斜面131部分反射形成的杂光到达所述光处理元件11的所述反射面112对于后续的成像效果造成影响。
在本发明的另一示例中,所述内框架124的中间位置并不形成有所述通孔1240,可以通过将所述内框架124的中间位置涂黑或者是增大粗糙度的方式来减少对于后期成像效果的影响。在本示例中,涂黑是指涂覆或者是施加特定波长光吸收率高的材料。根据本发明的另一方面,提供了一光转向机构10的制造方法,其包括如下步骤:

根据本发明的一实施例,在上述方法中,对应于所述光照区域1121但是非一全反射区域1122的至少部分所述支撑面121的反射率被设置为小于对应于所述全反射区域1122的至少部分的所述支撑面121的反射率。
根据本发明的一实施例,在上述方法中,在所述支撑面121分别形成一支撑 区域1211和一非支撑区域1212,其中所述非支撑区域1212的位置低于所述支撑区域1211的位置。
