下面结合图1至图19描述本申请实施例的光圈组件、摄像模组及电子设备。
如图1、图2、图3和图8所示，本申请实施例的光圈组件，包括：驱 动机构1、支撑座3以及多个叶片2。
支撑座3设有第一进光孔301，多个叶片2均转动连接于支撑座3，多个叶片2形成通光孔202，通光孔202与第一进光孔301相通，多个叶片2均与驱动机构1连接。
其中，在驱动机构1的驱动下，多个叶片2均可相对支撑座3旋转，通过多个叶片2的旋转调节通光孔202的进光量大小。
具体地，如图2和图3所示，支撑座3可以为长方体、圆柱体等，在此对支撑座3的具体形状不做限制，支撑座3上设有第一进光孔301，例如，第一进光孔301为圆形，第一进光孔301的尺寸根据实际需求设置，外部环境中的光线可以通过第一进光孔301。
如图8所示，多个叶片2可以通过转轴转动连接于支撑座3的一侧，多个叶片2沿支撑座3的周向均匀布设，每个叶片2与相邻的叶片2可以部分重叠，多个叶片2围合形成通光孔202，通光孔202与第一进光孔301相通，使得外部环境中的光线能够依次通过通光孔202和第一进光孔301。叶片2的数量根据实际需求设置，例如，支撑座3为长方体，沿支撑座3表面的周向均布有四个叶片2。
进一步地，如图4所示，叶片2的一端的内侧设置为弧形槽，弧形槽所在的圆弧的轴线与第一进光孔301的轴线同轴设置，多个叶片2围合形成的通光孔202为圆形，可以理解的是，在多个叶片2未发生旋转的情况下，此时围合形成的通光孔202的进光量最大。叶片2可以相对支撑座3顺时针旋转或者逆时针旋转，在叶片2顺时针旋转的情况下，通光孔202的进光量逐渐变小，则在叶片2逆时针旋转的情况下，通光孔202的进光量逐渐变大；或者在叶片2顺时针旋转的情况下，通光孔202的进光量逐渐变大，则在叶片2逆时针旋转的情况下，通光孔202的进光量逐渐变小。叶片2的数量可以尽量增多，以使得通光孔202的形状更接近圆形。
多个叶片2均与驱动机构1连接，在驱动机构1的驱动下，每个叶片2可相对支撑座3旋转，通过多个叶片2的同步旋转调节通光孔202的进光 量大小，即改变光圈的大小，从而改变穿过第一进光孔301的进光量。
例如，多个叶片2相对支撑座3逆时针旋转，通光孔202的进光量逐渐变小，多个叶片2相对支撑座3顺时针旋转，通光孔202的进光量逐渐变大，通过多个叶片2的旋转角度的不同可以获得进光量不同的通光孔202，即获得尺寸不同的光圈。
需要说明的是，光圈组件应用在摄像模组中，光圈组件安装在摄像模组的入光侧，以使得光线能够通过光圈组件入射到摄像模组的摄像头上，实现摄像模组对图像的采集和拍摄。
通过多个叶片2的旋转，使得光圈组件能够在不同尺寸的光圈之间切换，在拍摄的过程中，光圈越大，景深越浅，拍摄的画面就会出现前景清晰背景模糊的效果，光圈越小，景深越深，拍摄的画面就会出现前景和背景都很清晰的效果，同时在夜晚或者光线昏暗的环境中，为了保证足够的进光量，可以使用大光圈，大光圈尤其适合拍摄光线昏暗的环境和夜景。由此可以根据外部环境及需要的画面效果来调节光圈的大小以适应多种场景的拍摄。
在本申请实施例中，多个叶片2转动连接于支撑座3的一侧，多个叶片2围合形成通光孔202，驱动机构1驱动多个叶片2同步旋转，通过多个叶片2的旋转实现通光孔202的进光量大小的连续调节，由此实现进光量的连续调节，可以根据用户的需求、场景的变化等因素灵活调整光圈的大小，满足进光量的灵活控制，从而提升用户的拍摄体验。
在可选的实施例中，如图1和图5所示，光圈组件还包括支架4，支架4设有第二进光孔401，第一进光孔301与第二进光孔401相通，驱动机构与支架4连接，多个叶片2均与支架4连接。
其中，在驱动机构的驱动下，支架4可相对支撑座3旋转，在支架4的带动下，多个叶片2均可相对支撑座3旋转。
例如，在支架4的中间位置设有第二进光孔401，第二进光孔401的轴线与第一进光孔301的轴线同轴设置，第二进光孔401的进光量尺寸等于 或者大于第一进光孔301的进光量尺寸。
需要说明的是，支架4与支撑座3叠合布置，支架4与支撑座3之间留有间隙。在多个叶片2位于支架4与支撑座3之间的情况下，在驱动机构1的驱动下，支架4可绕第二进光孔401的轴线顺时针旋转或者逆时针旋转，在支架4的带动下，多个叶片2均相对支撑座3顺时针旋转或者逆时针旋转，由此实现通光孔202的进光量大小的调节。
在可选的实施例中，如图1、图5和图6所示，光圈组件还包括多个滑块5，滑块5与叶片2一一对应连接。
支架4转动连接于支撑座3背离叶片2的一侧，滑块5夹设于支架4和支撑座3之间。
滑块5的相对的两个侧面均设有导向柱，支撑座3和支架4均设有导向凹槽，导向凹槽与导向柱相适配。
位于支撑座3一侧的导向柱穿过支撑座3上的导向凹槽，且与叶片2连接，位于支撑座3另一侧的导向柱穿过支架4上的导向凹槽。
其中，在支架4的带动下，滑块5可相对于支撑座3移动，在滑块5的带动下，叶片2可相对支撑座3旋转。
如图5所示，支架4设于支撑座3的一侧，支架4与支撑座3为活动连接，多个叶片2设于支撑座3的另一侧，光线可以依次通过通光孔202、第一进光孔301和第二进光孔401。
如图1和图8所示，滑块5夹设于支架4和支撑座3之间，滑块5的数量与叶片2的数量相同，例如沿支撑座3的周向均匀布设有四个叶片2，四个滑块5的位置与四个叶片2的位置一一对应。
在驱动机构1的驱动下，支架4可绕第二进光孔401的轴线顺时针旋转或者逆时针旋转，在支架4的带动下，滑块5相对于支撑座3运动，滑块5可以靠近第一进光孔301的轴心或者远离第一进光孔301的轴心，在多个滑块5的带动下，多个叶片2相对支撑座3顺时针旋转或者逆时针旋转，由此实现通光孔202的进光量大小的调节。
在可选的实施例中，如图2、图3、图5和图6所示，导向柱包括第一导向柱501、第二导向柱502和第三导向柱503，导向凹槽包括第一导向凹槽302、第二导向凹槽303和第三导向凹槽402。
如图5所示，支架4设有第三导向凹槽402，支撑座3设有第一导向凹槽302和第二导向凹槽303。

如图2和图3所示，在叶片2的数量为四个的情况下，沿支撑座3的周向均匀布设有四组导向凹槽，每组导向凹槽包括一个第一导向凹槽302和一个第二导向凹槽303，第一导向凹槽302位于外侧，第二导向凹槽303位于内侧，第一导向凹槽302的长度大于第一导向凹槽302的长度。第一导向凹槽302和第二导向凹槽303均可以为条形槽，条形槽使得第一导向柱501能够沿第一导向凹槽302做直线运动，使得第二导向柱502能够沿第二导向凹槽303做直线运动。
如图5所示，支架4设有第三导向凹槽402，在叶片2的数量为四个的情况下，绕第二进光孔401的轴线环向阵列分布有四个第三导向凹槽402，在支架4绕第二进光孔401的轴线旋转的情况下，第三导向凹槽402绕第二进光孔401的轴线旋转，第三导向柱503能够相对第一导向凹槽302和第二导向凹槽303做直线运动。
如图8所示，第一导向柱501穿设于第一导向凹槽302且可沿第一导向凹槽302做直线移动，第一导向柱501与叶片2活动连接，第一导向柱501可带动叶片2旋转。第二导向柱502位于第二导向凹槽303中，且第二导向柱502的自由端位于叶片2以下，避免在叶片2旋转的过程中与叶片2发生磕碰，第二导向柱502沿第二导向凹槽303做直线移动。第三导向柱503位于第三导向凹槽402中，第三导向柱503的表面与第三导向凹 槽402的槽壁相接触，第三导向柱503沿第三导向凹槽402移动。
具体地，驱动机构1驱动支架4绕第二进光孔401的轴线旋转，第三导向凹槽402随着支架4绕第二进光孔401的轴线旋转，在第三导向凹槽402旋转的过程中，第三导向凹槽402驱使第三导向柱503沿与第一导向凹槽302和第二导向凹槽303相平行的方向做直线运动，此时第一导向柱501和第二导向柱502可分别沿第一导向凹槽302和第二导向凹槽303做直线运动，进一步，第一导向柱501带动叶片2旋转。
在可选的实施例中，第三导向凹槽402的一端与第二进光孔401的轴心的距离小于第三导向凹槽402的另一端与第二进光孔401的轴心的距离，多个第三导向凹槽402沿第二进光孔401的周向方向依次布设。
如图5所示，支架4设有第三导向凹槽402，在叶片2的数量为四个的情况下，绕第二进光孔401的轴线环向阵列分布有四个第三导向凹槽402，第三导向凹槽402的一端靠近第二进光孔401的轴心，第三导向凹槽402的另一端远离第二进光孔401的轴心，即第三导向凹槽402的一端与第二进光孔401的轴心的距离小于第三导向凹槽402的另一端与第二进光孔401的轴心的距离。第三导向凹槽402的两端与第二进光孔401的轴心的距离不同，在支架4绕第二进光孔401的轴线旋转的情况下，第三导向凹槽402绕第二进光孔401的轴线旋转，第三导向柱503能够相对第一导向凹槽302和第二导向凹槽303做直线运动。
在可选的实施例中，第一导向凹槽302和第二导向凹槽303平行布设，相邻的两个第一导向凹槽302垂直布设，相邻的两个第二导向凹槽303垂直布设。
定义沿支撑座3的周向均匀布设的四组导向凹槽分别为第一组导向凹槽、第二组导向凹槽、第三组导向凹槽和第四组导向凹槽，第一组导向凹槽的方向和第三组导向凹槽的方向一致，第二组导向凹槽的方向和第四组导向凹槽的方向一致，同时第一组导向凹槽的方向与第二组导向凹槽的方向相互垂直。每组导向凹槽包括一个第一导向凹槽302和一个第二导向凹 槽303，第一导向凹槽302和第二导向凹槽303平行布设。
在叶片2的数量为四个的情况下，滑块5的数量为四个，与第一组导向凹槽、第二组导向凹槽、第三组导向凹槽和第四组导向凹槽相对应的四个滑块5分为定义为第一滑块5、第二滑块5、第三滑块5和第四滑块5。第一滑块5和第三滑块5移动的方向相反，第二滑块5和第四滑块5移动的方向相反，同时第一滑块5和第二滑块5移动的方向相互垂直。在四个滑块5同时远离第二进光孔401的轴心移动的过程中，通光孔202的进光量逐渐变小，在四个滑块5同时靠近第二进光孔401的轴心移动的过程中，通光孔202的进光量逐渐变大。
如图4和图8所示，在可选的实施例中，叶片2设有第四导向凹槽201，第一导向柱501依次穿设于第一导向凹槽302和第四导向凹槽201。
具体地，叶片2远离第一进光孔301的一端设有第四导向凹槽201，第四导向凹槽201为条形槽，第四导向凹槽201的方向与第一导向凹槽302的方向相互垂直。第一导向柱501依次穿设第一导向凹槽302和第四导向凹槽201，且第一导向柱501的表面与第四导向凹槽201的槽壁相接触。
在第一导向柱501沿第一导向凹槽302直线移动的过程中，第一导向柱501的表面与第四导向凹槽201的槽壁相接触，第一导向柱501与第四导向凹槽201之间的抵接力驱使叶片2旋转。
在本申请实施例中，叶片2设有第四导向凹槽201，第一导向柱501依次穿设第一导向凹槽302和第四导向凹槽201，通过第一导向柱501与第四导向凹槽201之间的抵接力驱使叶片2旋转，结构简单，易于实现。
在可选的实施例中，如图1所示，驱动机构1包括电磁线圈101和磁体102，磁体102设于支架4；其中，在电磁线圈101处于通电状态的情况下，电磁线圈101和磁体102的配合可驱动支架4相对于支撑座3旋转。
具体地，磁体102可以为电磁铁或者永久磁铁，磁体102设于支架4的一侧，磁体102能够带动支架4旋转。在对电磁线圈101通入正向电流的情况下，电磁线圈101和磁体102之间的磁斥力，驱使磁体102沿着一 个方向做直线运动，磁体102带动支架4绕第二进光孔401的轴线逆时针旋转。在对电磁线圈101通入反向电流的情况下，电磁线圈101和磁体102之间的磁吸力，驱使磁体102沿着相反的方向直线运动，磁体102带动支架4绕第二进光孔401的轴线顺时针旋转。
可以理解的是，在对电磁线圈101通入正向电流的情况下，磁体102也可以带动支架4绕第二进光孔401的轴线顺时针旋转，在对电磁线圈101通入反向电流的情况下，磁体102带动支架4绕第二进光孔401的轴线逆时针旋转。
