具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
以下结合附图，详细说明本申请各个实施例公开的技术方案。
如图1-图14所示，本申请实施例公开一种摄像头模组，该摄像头模组具体可以包括摄像头主体100和可变光圈组件200。
摄像头主体100是摄像头模组中用于实现拍摄功能的核心部分，该摄像头主体100具体可以包括摄像头支架110、摄像头120、电路板130、感光芯片140等器件，摄像头120安装于摄像头支架110上，电路板130与摄像头支架110相连，感光芯片140设置于电路板130上。
可变光圈组件200具体可以包括依次叠置的底座210、叶片220和旋转部230，也就是说，叶片220位于底座210和旋转部230之间。叶片220与底座210铰接，因此叶片220可以相对于底座210旋转。叶片220的数量为多个，多个叶片220形成通光孔201，该通光孔201与摄像头主体100相对，因此外部环境中的光线可以通过该通光孔201进入摄像头主体100，以便于摄像头主体100实施拍摄功能。叶片220与旋转部230滑动配合，当旋转部230转动时，旋转部230可以带动叶片220转动。
在旋转部230旋转的情况下，旋转部230可以驱动叶片220相对于底座210旋转，通过叶片220的旋转可以调节通光孔201的孔径大小。在这一过程中，摄像头模组可以连续改变光圈，从而改变进光量。因此，该摄像头模组可以根据用户的需求、场景变化等因素灵活调整光圈，从而改善拍摄效果。例如，大光圈可以拍摄人物虚化的照片，小光圈可以拍摄长曝光照片。
可选地，在旋转部230沿第一方向旋转的情况下，通光孔201的孔径变大；在旋转部230沿第二方向旋转的情况下，通光孔201的孔径变小。其中， 这里所述的第一方向与第二方向相反。因此，只需要调整旋转部230的转动方向，就可以改变通光孔201的孔径大小的变化趋势，从而简化通光孔201的孔径大小的调节操作。
可选的实施例中，叶片220和旋转部230中，一者设有连接凸部240，另一者设有滑槽250，该连接凸部240的至少一部分可以位于滑槽250内，并且该连接凸部240与滑槽250滑动配合，以此实现叶片220与旋转部230的滑动配合。在旋转部230旋转的情况下，连接凸部240相对于滑槽250滑动，从而驱动叶片220相对于底座210旋转，以改变通光孔201的孔径大小。旋转部230的旋转方向不同时，叶片220的转动方向不同。具体地，当叶片220沿靠近摄像头主体100的光轴的方向转动时，通光孔201的孔径变小，此时摄像头主体100的视场角α将变小；反之，当叶片220沿远离摄像头主体100的光轴的方向转动时，通光孔201的孔径变大，此时摄像头主体100的视场角α将变大。
一种可选的实施例中，旋转部230的旋转轴线与摄像头主体100的光轴重合，旋转部230设有滑槽250。采用此种结构后，由于旋转部230的结构强度稍大于叶片220的结构强度，因此在旋转部230上设置滑槽250不会对整个可变光圈组件200的结构强度产生过大影响。同时，旋转部230不会影响通光孔201的孔径大小，因此滑槽250可以设置得更长，使得叶片220的转动幅度更大，以此强化连续改变光圈的效果。进一步地，叶片220远离通光孔201的一侧边缘设有连接凸部240，这样设计同样可以使叶片220的转动幅度增大，从而扩大光圈的变化范围。
在改变光圈的过程中，通光孔201的形状越接近圆形，摄像头主体100的成像效果更好。多个叶片220沿着环绕通光孔201的轴线的方向排布，此时连接凸部240和滑槽250的数量均为多个，多个连接凸部240与多个滑槽250一一对应配合。当旋转部230旋转时，多个叶片220可以同时相对于底座210旋转，从而使得通光孔201的形状接近圆形，以此优化摄像头主体100的成像效果。
上述叶片220具有第一端和第二端，该第一端与底座210铰接，第二端为自由端。随着叶片220的数量不断增加，各叶片220旋转时所需的空间也 就随之增大，为了尽量减小各叶片220所占用的空间，相邻的叶片220中，一个叶片220的第一端与另一个叶片220的第二端叠置，使得所有叶片220共同占用的空间更小。此时，在有限的空间内，叶片220的数量可以尽量增多，从而使得通光孔201的形状更接近圆形。
具体地，底座210开设有第一孔202，旋转部230开设有第二孔203，这里的第一孔202和第二孔203均与通光孔201相连通。第一孔202和第二孔203的孔径大小基本不变，因此各叶片220旋转时，仅通光孔201的孔径大小发生变化。叶片220可相对于底座210在第一位置和第二位置之间转动，摄像头主体100具有光轴方向，此时：在第一位置，各叶片220沿光轴方向的正投影位于第一孔202沿光轴方向的正投影之外，此时通光孔201的孔径最大；在第二位置，各叶片220沿光轴方向的正投影与第一孔202沿光轴方向的正投影至少部分重合，此时通光孔201的孔径变小。采用此种方案时，叶片220处于第一位置时，通光孔201的孔径可以最大化，从而更好地满足用户的拍摄需求。
叶片220的背对两侧分别具有第一边沿221和第二边沿222，该第一边沿221和第二边沿222均为弧形边沿，底座210具有外环面和内环面，在第一位置，第一边沿221与外环面对齐，第二边沿222与内环面对齐。一方面，叶片220的第二边沿222设置为弧形边沿时，更有利于使通光孔201的形状趋近于圆形；另一方面，该结构可以使叶片220的尺寸尽量大，从而拓宽摄像头模组的光圈变化范围。
上述滑槽250的形状可以灵活选择，例如该滑槽250可以是矩形槽、椭圆形槽等，为了使得叶片220旋转时更加稳定，本申请实施例可选滑槽250为弧形槽。当滑槽250设置为多个时，各滑槽250所在圆弧的圆心可以位于同一圆周上，使得叶片220旋转时的同步性更高，从而使得所形成的通光孔201更趋近于圆形孔，以提升摄像头模组的拍摄效果。
为了便于驱动旋转部230旋转，可以在旋转部230的边缘设有第一驱动齿231。具体实施例中，可以通过驱动马达驱动旋转部230旋转，此时驱动马达可以与传动齿轮连接，该传动齿轮与旋转部230的第一驱动齿231啮合，当驱动马达驱动传动齿轮转动时，旋转部230随之转动。
底座210和叶片220的铰接位置可以灵活选择，可选地，在底座210的邻近通光孔201的一侧边缘设有铰接凸部211，同时在叶片220的邻近通光孔201的一侧边缘设有铰接孔223，该铰接凸部211与铰接孔223相配合。如此设置后，当叶片220旋转时，叶片220的大部分结构可以参与形成通光孔201，使得通光孔201的形状更趋近于圆形，而不容易形成锯齿感，以此提升摄像头模组的拍摄效果。
本申请实施例还公开一种电子设备，该电子设备包括上述任一实施例所述的摄像头模组，该电子设备还包括壳体300，摄像头模组设置于该壳体300内。此外，该电子设备还可以包括镜片400和装饰圈500，镜片400和装饰圈500均设置于壳体300上，镜片400与前文所述的通光孔201相对，从而供光线穿过，装饰圈500可以沿着镜片400的边缘设置。
具体地，可以通过驱动马达驱动旋转部230旋转，但是这种驱动方式存在结构复杂、成本高等缺陷，因此为了简化电子设备的结构，同时降低电子设备的成本，该电子设备还可以包括控制旋钮600，该控制旋钮600可相对于壳体300旋转，可选地，控制旋钮600可以通过转轴700可转动地设置于壳体300上。壳体300开设穿孔，该穿孔可以设置于壳体300的顶部，或者侧部，控制旋钮600的一部分位于穿孔内，控制旋钮600与旋转部230相连，以驱动旋转部230旋转。需要改变摄像头模组的光圈时，用户可以通过控制旋钮600位于穿孔内的部分驱动旋转部230旋转。
具体实施例中，上述控制旋钮600可以是杆状件，其可以与旋转部230活动连接，当控制旋钮600相对于壳体300旋转时，其可以拉动旋转部230，从而驱动旋转部230旋转。但是这种结构会造成旋转部230的旋转幅度过小，致使光圈的调整效果不佳。为此，可以在旋转部230的边缘设置第一驱动齿231，控制旋钮600的边缘设有第二驱动齿610，第一驱动齿231与第二驱动齿610啮合。此时，控制旋钮600为盘状结构，用户驱动该控制旋钮600转动时，该控制旋钮600可以通过第一驱动齿231和第二驱动齿610驱动旋转部230转动。此时，控制旋钮600的旋转角度不受到限制，因此可以最大程度地驱动旋转部230旋转。
为了提升旋转部230旋转时的稳定性，电子设备还可以包括旋转轴承 800，旋转部230通过该旋转轴承800与壳体300配合。当旋转部230旋转时，旋转轴承800与壳体300滚动配合，从而使得旋转部230与壳体300之间的间隙基本不发生变化，从而提升旋转部230旋转时的稳定性，使得叶片220的旋转更加稳定。
本申请实施例所公开的电子设备可以为智能手机、平板电脑、电子书阅读器或可穿戴设备。当然，该电子设备也可以是其他设备，本申请实施例对此不做限制。
本申请上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
