 本发明的实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本发明。但是本发明能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下做类似改进，因此本发明不受下面公开的具体实施例的限制。
参阅图1至图3，图1示意出了本发明一实施例的光学采集模组的分解结构示意图，图2示意出了本发明一实施例的光学采集模组的其中一视角结构示意图，图3示意出了本发明一实施例的光学采集模组的另一视角结构示意图。本发明一实施例提供的一种反射模组，反射模组包括具有安装空间14的基座10、收容于所述安装空间14的支架20、固定于支架20的棱镜40、弹性连接支架20与基座10的弹性复位件30以及驱动支架20相对基座10运动的驱动组件。弹性复位件30具有相互垂直设置的第一轴线N（第一轴线N如图9或图10所示）、第二轴线M（第二轴线M如图8或图10所示）以及第三轴线O（第三轴线O如图10所示），驱动组件驱动支架20分别绕第一轴线N以及第二轴线M转动,以实现光学防抖的功能。
上述的反射模组，在进行工作过程中，若驱动组件驱动支架20绕第一轴线N转动以实现光学防抖功能，同时由于支架20转动时压缩弹性复位件30，这样在反射模组结束工作时弹性复位件30能实现支架20的复位；同理，若驱动组件驱动支架20绕第二轴线M转动，支架20在转动时同样会压缩弹性复位件30，这样弹性复位件30同样能实现支架20复位。如此可见，支架20分别绕弹性复位件30的第一轴线N以及第二轴线M转动时同步带动棱镜40进行动作，从而调整入射光线的角度实现光学防抖的功能，同时弹性复位件30能实现支架20沿两个轴向旋转后的复位动作，整体结构相对简单，占用空间小且制造成本较低。
在一个具体的实施例中，请参阅图1、图4至图6，图4示意出了本发明一实施例的光学采集模组的俯视结构示意图，图5示意出了图4在A-A处剖开位置的其中一视角图，图6示意出了图4在B-B处剖开位置的其中一视角图。基座10包括第一底面板11、第一背面板12及相对设置的两个第一侧面板13。第一底面板11、第一背面板12及两个第一侧面板13围合形成安装空间14。支架20可活动地设置于安装空间14中，支架20用于装设棱镜40，支架20的相对两个侧面与两个第一侧面板13一一对应设置并均设有第一活动间隔，支架20的背面与第一背面板12设有第二活动间隔。弹性复位件30设置于第二活动间隔中。支架20的背面通过弹性复位件30与第一背面板12相连，驱动组件用于驱动支架20移动。
需要说明的是，支架20的侧面指的是支架20上与第一侧面板13相对的面，支架20的背面指的是支架20上与第一背面板12相对的面。
需要说明的是，上述的第一底面板11、第一背面板12及两个第一侧面板13围合形成的安装空间14并非是封闭式安装空间。此外，第一底面板11分别与第一背面板12及两个第一侧面板13相连，和/或，第一背面板12分别与第一底面板11、及两个第一侧面板13相连。
这样在进行工作过程中，若驱动组件驱动支架20在第一底面板11的板面上转动，支架20在第一底面板11的板面上转动时压缩弹性复位件30，这样弹性复位件30能实现支架20复位；若驱动组件驱动支架20以与支架20的背面、第一底面板11的板面均平行的轴线为转轴中心线进行转动，支架20在转动时同样会压缩弹性复位件30，这样弹性复位件30同样能实现支架20复位。如此可见，支架20移动时同步带动棱镜40进行动作，进而能实现棱镜40相对于基座10移动，同时在第二活动间隔中设置的弹性复位件30能实现支架20的复位动作，整体结构相对简单。
请参阅图1、图7至图9，图7示意出了本发明一实施例的光学采集模组隐藏掉柔性线路板及基座10的结构示意图，图8示意出了图7的俯视图，图9示意出了图7的侧视图。在一个实施例中，驱动组件包括第一驱动组件以及第二驱动组件。第一驱动组件包括沿平行于第一轴线N方向相对设置于支架20上和基座10上的第一线圈52以及第一磁钢。第二驱动组件包括沿平行于第二轴线M方向相对设置于支架20和基座10上的第二线圈54以及第二磁钢。
在一个具体的实施例中，驱动组件包括第一驱动组件。第一驱动组件包括两个第一磁钢板51与两个第一线圈52。两个第一线圈52与第一磁钢板51一一相对设置，两个第一磁钢板51一一对应设置于支架20的相对两个侧面。两个第一线圈52与两个第一侧面板13一一对应设置，且第一线圈52与第一侧面板13相对固定。如此，第一驱动组件在进行工作时，两个第一线圈52均通电，其中一个第一线圈52作用于其位置相对的第一磁钢板51，第一磁钢板51在磁力作用下运动以实现支架20绕第一轴线N（第一轴线N如图9或图10所示）在第一底面板11上转动。
此外，进一步地，驱动组件还包括第二驱动组件。第二驱动组件包括两个第二磁钢板53与两个第二线圈54。两个第二线圈54与第二磁钢板53一一相对设置，两个第二磁钢板53相对间隔地设置于支架20的背面，第二线圈54与基座10相对固定设置。如此，第二驱动组件在进行工作时，两个第二线圈54均通电，其中一个第二线圈54作用于其位置相对的第二磁钢板53，第二磁钢板53在磁力作用下运动以实现支架20绕第二轴线M（第二轴线M如图8或图10所示）转动。
如图10所示，在一个实施例中，弹性复位件30关于第二轴线M以及第三轴线O对称。如此，驱动组件驱动支架20绕第一轴线N转动时运行效果较为稳定；同样地，驱动组件驱动支架20绕第二轴线M转动时运行效果较为稳定。
本实施例中，第一轴线N为垂直于水平面方向，弹性复位件30绕第一轴线N在水平面方向上进行转动；第二轴线M为平行于水平面方向，弹性复位件30绕第二轴线M进行翻转动作。
请参阅图11及图12，图11示意出了本发明一实施例的光学采集模组的支架20的其中一视角结构图，图12示意出了本发明一实施例的光学采集模组的支架20的另一视角结构图。在一个实施例中，支架20的侧面设有第一安装板21。第一安装板21上设有与第一磁钢板51相适应的第一安装槽211，第一磁钢板51装设于第一安装槽211中。
需要说明的是，该“第一安装板21”可以为“支架20的一部分”，即“第一安装板21”与“支架20的其他部分”一体成型制造；也可以是与“支架20的其他部分”可分离的一个独立的构件，即“第一安装板21”可以独立制造，再与“支架20的其他部分”组合成一个整体。如图11或图12所示，一实施例中，“第一安装板21”为“支架20”一体成型制造的一部分。
请参阅图1、图11及图12，在一个实施例中，支架20的背面设有相对间隔设置的两个第二安装板22。第二安装板22上设有与第二磁钢板53相适应的第二安装槽221，第二磁钢板53装设于第二安装槽221中。此外，弹性复位件30处于两个第二安装板22的间隔中。如此设置，有效减小了反射模组的占用空间。
需要说明的是，第一线圈52与第一侧面板13相对固定指的是，第一线圈52可以直接固定于第一侧面板13上，也可以是间接固定于第一侧面板13上。
请参阅图13及图14，图13示意出了本发明一实施例的光学采集模组的基座10的其中一视角结构图，图14示意出了本发明一实施例的光学采集模组的基座10的另一视角结构图。进一步地，第一背面板12上设有窗口121。窗口121处设置有可打开的盖板122，打开盖板122，便于将弹性复位件30装设于第二活动间隔中。
请参阅图1与图10，图10示意出了本发明一实施例的光学采集模组的弹性复位件30的结构示意图。在一个实施例中，弹性复位件30包括固定连接支架20的第一板31、固定连接基座10的第二板32，连接第一板31以及第二板32的连接件33。固定连接支架20的第一板31相对于固定连接基座10的第二板32分别绕第一轴N以及第二轴M转动。
如图10所示，连接件33为两个并关于第三轴线O对称设置，两个连接件33分别连接第一板31与第二板32位于第三轴线O同侧的一端，其中一个连接件33包括与第一板31连接的第一连接部331、与第二板32连接的第二连接部332以及朝向第三轴线O凸起并连接第一连接部331与第二连接部332的弹力部333，第一连接部331与第二连接部332相对间隔设置，如此更有利于弹性复位件30在受力的时候发生弹性形变，从而提供反射模组复位的作用力，当第一板31相对于第二板32分别绕第一轴N以及第二轴M转动时，弹力部333会发生相应的弹性形变，由此能够提供反射模组复位时的作用力。
具体而言，第一板31与支架20的背面粘接、铆接、焊接或采用安装件（安装件例如螺钉、螺钉、销钉等等）相连固定，第二板32与基座10的第一背面板12的连接方式类似，不再赘述。
进一步地，连接件33的材料的杨氏模量大于350MPa且小于750MPa。如此设置，一方面，在第一驱动组件的外力作用下，弹性复位件30能便于绕第一轴线N进行转动，另一方面，在第二驱动组件的外力作用下，有利于弹性复位件30绕第二轴线M进行转动。
在其他可选的实施例中，弹性复位件30还可以设置为其他的形状，例如弹性复位件30在第一底面板11上的投影为“工”字形状或“王”字形状。如此，弹性复位件30的两侧为镂空结构，受力时侧部容易被压缩变形，从而能实现支架20在第一底面板11的板面上轻松转动调整位置，且支架20转动过程中压缩弹性复位件30能实现支架20复位。
作为一个示例，弹性复位件30在第一底面板11上的投影为“工”字空心字体形状或“王”字空心字体形状。
需要说明的是，弹性复位件30为塑料材质的弹性件，也可以为金属材质的弹性件，还可以为硅胶材质的弹性件，在此不进行限定。
还需要说明的是，第一板31、第二板32及连接件33三者各自独立制造后再相互连接，当然也可以是通过注塑的方式一体化制造，在此不进行限定。
请再参阅图1，在一个实施例中，反射模组还包括柔性电路板60。柔性电路板60装设于基座10上，柔性电路板60分别与第一线圈52、第二线圈54电性连接。
进一步地，柔性电路板60包括第一电路板61、相对设置的两个第二电路板62及相对设置的两个第三电路板63。第一电路板61分别与第二电路板62、第三电路板63电性连接。第一电路板61叠置设置于第一背面板12上，两个第二电路板62对应叠置设于两个第一侧面板13上，两个第三电路板63分别位于基座10的顶面与底面。两个第一线圈52与两个第二电路板62一一对应电性连接，两个第二线圈54与两个第三电路板63一一对应电性连接。
具体而言，两个第二电路板62位于基座10的外侧，第一侧面板13上设有与第一线圈52相应的第一开口131，第一线圈52设置于第一开口131中。此外，第一底面板11上设有第二开口111。其中一个第三电路板63位于第一底面板11的底侧，其中一个第二线圈54位于第二开口111中并与第三电路板63电性连接。
在一个实施例中，一种光学采集模组，包括上述任一实施例反射模组，还包括棱镜40，棱镜40装设于支架20上。
上述的光学采集模组，在进行工作过程中，若驱动组件驱动支架20绕第一轴线N转动，支架20转动时压缩弹性复位件30，这样弹性复位件30能实现支架20复位；若驱动组件驱动支架20绕第二轴线M转动，支架20在转动时同样会压缩弹性复位件30，这样弹性复位件30同样能实现支架20复位。如此可见，支架20移动时同步带动棱镜40进行动作，进而能实现棱镜40相对于基座10移动，同时弹性复位件30能实现支架20的复位动作，整体结构相对简单。
在一个实施例中，一种电子设备，包括上述任一实施例光学采集模组。
上述的电子设备，由于包括上述的光学采集模组，其技术效果由光学采集模组带来，有益效果与光学采集模组的有益效果相同，在此不进行赘述。
