本申请要求在2020年02月17日提交中国专利局、申请号为202020175513.7、申请名称为“一种摄像模组及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端设备技术领域，尤其涉及一种摄像模组及电子设备。
背景技术
单反相机中，用于调节进光量大小的可变光圈具有多个档位，可以对进光量进行调节，从而满足不同条件下相机对亮度的要求。其中，将光圈安装于镜头内需要具备较高的组装精度，以获得高质量的图像。
随着科技的发展，诸如手机、平板电脑之类的电子设备对摄像功能的要求也越来越高，以期实现接近单反的摄像效果，但是目前光圈与镜头之间的组装方式难度较大，难以应用到这类小型的电子设备上。
发明内容
本申请提供一种摄像模组及电子设备，以满足小型电子设备的高质量成像需求。
本申请公开了一种可应用于诸如手机、平板电脑之类的电子设备的摄像模组，这种摄像模组集成有可变光圈，可以满足这类电子设备更高的摄像要求。该摄像模组具体包括摄像马达、镜头、图像传感器组件以及可变光圈；摄像马达包括对焦部，对焦部用于驱动镜头沿光轴方向移动，从而满足摄像的对焦要求；具体地，对焦部具有底座、载座以及驱动器，此处的底座相当于固定部，为其他结构提供支撑，而载座则相当于活动部；驱动器固定于载座，用于驱动载座相对底座沿设定方向移动，此处的设定方向即镜头的光轴方向；沿该设定方向，载座形成有安装孔；镜头固定于载座的安装孔内，可以随载座一起沿光轴方向移动，实现对焦；镜头具有入光侧，可变光圈被固定于载座上且位于镜头的入光侧，可变光圈具有进光孔，进光孔的直径可调节；外部的光线经过可变光圈调节后进入镜头；而图像传感器组件则设置于镜头的出光侧，具体地，图像传感器组件固定于底座上，经过镜头的光线最终到达图像传感器组件显影成像。此处的图像传感器组件可以包括图像传感器以及其他的外联器件和支撑结构。
上述摄像模组中可变光圈和镜头均设置于对焦部的载座上，可变光圈和镜头能够同时沿光轴方向移动实现对焦，而可变光圈又相对镜头独立，降低了摄像模组的组装难度，有利于实现摄像模组的小型化，使得该摄像模组可以应用诸如手机这样小型的电子设备中；而且，可变光圈对进光孔的调节可以不受镜头的运动影响，可以满足更高质量的摄像需求。
由于镜头和可变光圈同时固定在对焦部的载座上，而可变光圈又需要设置于镜头的入光侧，为了方便固定安装，在载座上设置有用于承载可变光圈的支撑部，可变光圈可以固 定在支撑部上；此处的支撑部可以凸出于摄像马达，当然，支撑部需要根据镜头的尺寸调整，以满足镜头与可变光圈的安装需求。
一种可能的实现方式中，摄像马达还可以包括顶盖和防抖部，顶盖与防抖部上下配合形成用于容纳上述对焦部的容纳空间，对焦部具体可以固定于防抖部。在摄像模组使用中，防抖部可以带动镜头在垂直于光轴的平面内移动，削弱摄像模组在使用中晃动对成像质量的不利影响。当然，在顶盖上需要开设用于光线穿过的第一光孔，第一光孔的轴心线与光轴共线。
一种可能实现的方式中，对焦部中的驱动器可以包括驱动线圈和驱动磁铁，其中，驱动线圈设置于载座上，驱动磁铁则对应设置在底座上。使得驱动线圈与驱动磁铁相对，对驱动线圈通电，驱动线圈产生电场，驱动磁铁位于该电场中可以被驱动移动。改变驱动线圈中的电流大小以及电流方向可以对驱动磁铁的运动进行调节。可以理解的是，此处的驱动磁铁设置于底座上，驱动线圈设置于载座上，是为了限定驱动磁铁与驱动线圈的相对驱动的形式，即驱动磁铁相当于固定端，驱动线圈相当于活动端，因此，驱动磁铁还可以设置在其他结构上，例如与底座位置相对固定的顶盖。
在本申请所提供的摄像模组中，可变光圈相对于镜头独立，可以单独使用。具体地，可变光圈可以包括驱动结构以及多个叶片，多个叶片环形设置可以形成供光线穿过进入镜头的进光孔，驱动结构即用于驱动多个叶片运动以改变该进光孔的大小，从而实现进光量的调节，当可变光圈单独使用，对驱动结构添加电源，驱动结构即可运动以驱动叶片动作进而改变进光孔的大小。
对焦部还可以包括用作控制装置的控制组件，控制组件具体固定于底座上，控制组件与驱动器电连接以控制驱动器动作，控制组件还可以通过连接组件与上述可变光圈的驱动结构电连接，从而可以控制驱动结构对可变光圈的进光孔大小进行调节；因此，此处控制组件与可变光圈的驱动结构信号连接，而连接组件在可变光圈与控制组件之间可以充当电器讯号导通的结构。
在一种可能实现的方式中，上述连接组件可以以第一簧片的形式实施，第一簧片设置于载座朝向可变光圈的一侧，第一簧片为金属材质，具体可以为铜或铜合金；第一簧片分别与上述控制组件以及可变光圈的驱动结构电连接，以实现控制组件与可变光圈的电器讯号连接。
在另一种可能实现方式中，上述连接组件可以以第一簧片组合形成于载座上的连接电路实现；该连接电路可以直接在载座上走线形成，也可以在载座上贴附柔性电路板形成，可变光圈的驱动结构与该连接电路电连接；此处的第一簧片与上述第一簧片类似，设置于载座朝向可变光圈的一侧，不同点在于，此处的第一簧片与控制组件电连接，并与载座上的连接电路电连接；因此，在该方式中，可变光圈的驱动结构与控制组件之间的电器讯号通过第一簧片和载座上的连接电路共同实现。
如上述两种实施方式中，第一簧片在控制组件与可变光圈的驱动结构之间充当了至少一部分电器讯号传递载体，为了增强电器讯号的传递效果，第一簧片可以根据其具体结构分割为多个同层设置的子簧片；例如，多个子簧片可以以光轴为中心环形分布。
需要说明的是，上述第一簧片除了用作电气讯号载体，还可以充当载座与摄像模组固定部(例如底座、防抖部或顶盖)之间的连接件，此处，可以将第一簧片连接于载座与顶盖之间。对应于第一簧片，还可以在载座朝向图像传感器组件的一侧设置第二簧片，第二 簧片可以连接载座与底座；由于第一簧片和第二簧片分别位于载座的两侧，第一簧片和第二簧片自两个相对的方向对载座施加相反方向的作用，使得载座相当于处于一个相对稳定的状态，当然，由于第一簧片和第二簧片的弹性特质，载座的依旧可以被驱动器驱动以相对底座移动。
在上述两种实现方式中，由于第一簧片充当至少一部分电器讯号传递的载体，因此，第一簧片属于电性连接结构；需要考虑的是，本申请所提供的摄像模组还设置有其他的电性器件(例如驱动器中的驱动线圈和驱动磁铁)，为了防止第一簧片与该类电性器件相互干扰，可以在第一簧片与这类结构之间设置绝缘隔离结构。具体地，可以在第一簧片与驱动磁铁之间设置隔挡件，而载座可以充当第一簧片与驱动线圈之间的绝缘隔离结构。当然，隔档件的结构不做限定，可以是平板形，还可以是档条；当然，绝缘隔离结构相对于第一簧片的设置位置可以根据其他的电性器件的相对位置确定，此处并不限定。
考虑到结构的完整性，对焦部还可以包括外壳，外壳与上述底座上下配合以形成用于容纳载座与驱动器的容纳空间；当然，上述第一簧片、第二簧片也容纳在内，在外壳与第一簧片之间还可以设置隔框以起到隔离作用。
基于上述技术方案，本申请还公开一种电子设备，该电子设备可以为手机、平板电脑，具体地，摄像模组安装于设备本体上，以实现摄像功能，上述摄像模组具有可多档调节的光圈，可以满足更高的摄像需求。

具体实施方式
在单反相机中，可变光圈是可以配合快门调节进光量的结构。目前应用于单反相机的可变光圈一般安装于镜头内，对摄像模组的组装提出了高难度要求，使得具有可变光圈的摄像模组无法直接转用于手机、平板电脑此类电子设备中。因此，本申请提出了一种摄像模组，在满足对焦调整中镜头与可变光圈同步移动的条件下，使得镜头与可变光圈的结构相对独立，可以降低摄像模组的组装难度；基于这种结构，摄像模组可以更容易做到轻薄化设计，因此，可以将这种摄像模组应用到小型电子设备中，满足小型电子设备日渐提升的成像质量要求。可以理解的是，此处的电子设备可以是手机、平板电脑、车载监控等。
为了更加清晰地描述本申请实施例的技术方案，下面结合附图对本申请所提供的摄像模组作进一步地详细描述。其中，应该理解的是，下文中的“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
本申请实施例提出的一种摄像模组10，如图1所示，该摄像模组10包括摄像马达1、镜头2、可变光圈3以及图像传感器组件4，摄像马达1相当于摄像模组10的动力源，在摄像作业中用于驱动镜头2和可变光圈3移动，以满足成像需求。图1中还示出了可变光圈3形成的进光孔J，在工作中，外部光线经可变光圈3的进光孔J进入镜头2，穿过镜头2后投射在图像传感器组件4上显影成像。镜头2以图1所示的方式安装于摄像马达1内，使得光线穿过镜头2后可以抵达位于摄像马达1背离可变光圈3的一端的图像传感器组件4显影成像。可变光圈3可以通过凸出于摄像马达1的支撑部A固定于摄像马达1，从而，可变光圈3和镜头2可以同时被摄像马达1驱动。此处的图像传感器组件4包括图像传感器以及其他的外联器件和支撑结构。
具体地，如图2所示的摄像马达1的结构，摄像马达1包括有对焦部11、顶盖12以及防抖部13，顶盖12和防抖部13上下配合形成用于容纳对焦部11的容纳空间，对焦部11具体固定于防抖部13上。上述镜头2和可变光圈3固定于对焦部11上，对焦部11可以驱动镜头2和可变光圈3沿光轴方向(即图2所示Z方向)移动，实现对焦；而防抖部13可以驱动对焦部11在垂直于光轴方向的面上移动，实现镜头2防抖效果。当然，上述用于支撑固定可变光圈3的支撑部A设置于对焦部11上，且伸出于摄像马达1外。在顶盖12上，形成有供光线穿过的第一光孔121，第一光孔121的轴心线与光轴共线。
对焦部11的结构可以参照图3，图3示出了对焦部11的立体结构，对焦部11具体包括外壳111、底座112、载座113以及驱动器114，外壳111和底座112上下配合形成用于容纳载座113和驱动器114的容纳空间，由于外壳111遮挡，图3中未示出驱动器114的 结构。
请结合图2和图3的结构参照图4所示的摄像马达1的剖面结构示意图，对焦部11中的驱动器114以驱动线圈1141与驱动磁铁1142的形式实现，其中，驱动线圈1141设置于载座113上，驱动磁铁1142则可以固定于底座112上。在工作中，底座112相当于固定部，载座113相当于活动部，驱动器114用于驱动载座113相对底座112沿光轴方向移动。使得驱动线圈1141与驱动磁铁1142相对，当驱动线圈1141通电，驱动线圈1141产生电场，驱动磁铁1142位于该电场中可以被驱动移动；改变驱动线圈1141中的电流大小以及电流方向可以对驱动磁铁1142的运动进行调节。当然，驱动器114的还可以以其他形式实现，此处不做限定。另外，在这种实施方式中，驱动线圈1141设置于载座113上相当于驱动器114的活动端，驱动磁铁1142固定于底座112相当于驱动器114的固定端，以实现相对驱动运动，因此，驱动磁铁1142还可以设置于其他与底座112相对位置固定的结构上，例如，驱动磁铁1142还可以固定于顶盖12上，依旧能够达到驱动磁铁1142驱动驱动线圈1141运动的效果。
上述摄像模组10中可变光圈3和镜头2均设置于对焦部11的载座113上，可变光圈3和镜头2能够同时沿光轴方向移动实现准确对焦，而可变光圈3又相对镜头2独立，相当于降低了摄像模组10的组装难度，有利于实现摄像模组10的小型化，使得该摄像模组10可以应用诸如手机这样小型的电子设备中；而且，可变光圈3对进光孔的调节可以不受镜头2的运动影响，可以满足更高质量的摄像需求。其中，外壳111的结构可以参照图5所示，在外壳111上形成有供光线穿过的第二光孔1111，此处并不限定通孔第二光孔1111的具体形状，图5中的形状仅为示例。底座112的结构可以参照图6，在底座112上形成有供光线穿过的第三光孔1121。可以理解的是，当摄像马达1与镜头2组装在一起，第二光孔1111和通孔第三光孔1121的轴心线均与镜头2的光轴共线。
载座113的结构可以参照图7所示，载座113形成有安装孔1131。在与镜头2组装配合时，镜头2固定于该安装孔1131内，当然，该安装孔1131的轴心线与镜头2的光轴共线，以保证成像效果。上述用于固定可变光圈3的支撑部A形成在载座113上。
在图4所示例的驱动器114结构中，驱动线圈1141设置于载座113上，一种可能的实现方式中，结合图7所示的载座113的结构，在载座113的周侧形成有安装槽M，在该安装槽M内设置驱动线圈1141，得到如图8所示的结构。
为了控制驱动器114，对焦部11还包括有控制组件115，具体如图9所示，控制组件115可以设置于底座112上。此处的控制组件115可以控制驱动器114，还可以与外部主控结构实现信息交互。在图9所示的结构中，控制组件115以一端固定于底座112的方式设置于底座112上，控制组件115还可以以贴附的形式集成于底座112上，或者以其他结构形式设置与底座112上，此处不做限定。当然，控制组件115属于本实施例中摄像模组10的一部分，当然还可以设置在其他结构上，并不影响控制组件115的功能实现。
需要说明的是，本申请所提供的摄像模组10中，可变光圈3不仅仅是结构上与镜头2相对独立，其工作也可以相对镜头2独立。可变光圈3可以以图10所示的结构作为参考，该可变光圈3包括有壳体31以及设置于壳体31内的驱动结构32和多个叶片33，多个叶片33环绕设置一形成进光孔J，当然，此处进光孔J的轴心线与镜头2的轴心线共线。多个叶片33可以在驱动结构32的驱动下旋转，从而改变进光孔J的大小，达到改变进光量的目的。当可变光圈3单独使用，只要对驱动结构32施加电源，即可启动驱动结构32从 而驱动叶片33旋转以改变进光孔J的大小。
一种可能实现的方式中，可变光圈3的工作还可以由上述驱动组件115控制。为了实现控制组件115对于可变光圈3的控制，就需要在控制组件115与可变光圈3的驱动结构32之间形成可以传递电器讯号的结构。
在一种可能实现的方式中，如图11所示，在载座113朝向可变光圈3的一侧设置有第一簧片116，第一簧片116与固定于底座112上的控制组件115电连接(如图12所示)，具体地第一簧片116为金属材质，具体可以为铜或铜合金或其他导电性良好的金属。当然，第一簧片116充当可变光圈3与控制组件115之间的电器信号传递载体，因此，控制组件115、第一簧片116、可变光圈3的驱动结构32之间的连接结构可以如图13所示。
在另一种可能实现的方式中，与图13所示的结构类似，不同的地方在于，第一簧片116未直接与可变光圈3的驱动结构32直接接触实现电连接，而是如图14所示例的，在载座113的支撑部A上可以形成与可变光圈3的驱动结构32电连接的连接电路117，该连接电路117与第一簧片116电连接，从而，通过连接电路117和第一簧片116实现可变光圈3的驱动结构32与控制组件115之间的电器讯号传递。此处，形成在载座113上的连接电路117可以以在载座113上直接走线形成，也可以是将柔性电路集成到载座113上。
在上述两种实施方式中，第一簧片116在控制组件115与可变光圈3的驱动结构32之间充当了至少一部分电器讯号传递载体，为了增强电器讯号的传递效果，第一簧片116可以根据其具体结构分割为多个同层设置的子簧片1161，如图15所示的一种第一簧片116的结构，多个子簧片1161可以以光轴为中心环形分布。
另外，在上述两种实现方式中，由于第一簧片116充当至少一部分电器讯号传递的载体，因此，第一簧片116属于电性连接结构；需要考虑的是，本实施例所提供的摄像模组10上还可能设置有其他的电性器件(例如上述驱动器114所包含的驱动线圈1141以及驱动磁铁1142)，为了防止第一簧片116与该类电性器件相互干扰，可以在第一簧片116与该类电性器件之间设置绝缘隔离结构。例如图16所示，可以在第一簧片116与驱动磁铁1142之间设置隔档件118。根据图8所示的结构，驱动线圈1141设置于载座113的凹槽内，载座113充当了第一簧片116与驱动线圈1141之间的绝缘隔离结构。当然，隔档件118的结构不做限定，可以是平板形，还可以是档条；另外，隔挡件118相对于第一簧片116的设置位置也可以根据其他的电性器件的相对位置确定，此处并不限定。
需要说明的是，上述第一簧片116除了用作电器讯号载体，还可以充当载座113与摄像模组10的固定部(例如底座112或外壳111)之间的连接件，此处，可以将第一簧片116连接于载座113与外壳111之间。对应于第一簧片116，如图17所示，还可以在载座113朝向图像传感器组件4的一侧设置第二簧片119，第二簧片119可以连接载座113与底座112；由于第一簧片116和第二簧片119分别位于载座113的两侧(图17中所示为上下两侧)，第一簧片116和第二簧片119自两个相对的方向对载座113施加相反方向的作用力，以使载座113处于一个相对稳定的状态，当然，由于第一簧片116和第二簧片119的弹性特质，载座113的依旧可以被驱动器114驱动以相对底座112移动。
基于上述对本申请所提供的摄像模组10的结构介绍，可以参照图18所示的一种摄像模组10的结构爆炸图，如图18中所示例的，该摄像模组10中，驱动器114以驱动线圈1141配合驱动磁铁1142的方式实现，且驱动线圈1141环绕在载座113的周侧，而驱动磁铁1142则以两个对称条形磁铁的方式实现以配合驱动线圈1141；第一簧片116与驱动磁 铁1142之间通过两个长条形的隔档件118实现分隔；在外壳111与第一簧片116之间，还可以设置一矩形隔框14，防止第一簧片116与外壳111接触，当然，隔框14还可以以其他形状实现，此处不做限定；其他结构已在上文中做了介绍，此处不再赘述，当然，图18仅以示例的形式提供一种摄像模组10的结构，并不对本申请所要保护的摄像模组10的结构做限定。
由于上述摄像模组10的结构可以实现小型化，因此该摄像模组10可以应用到小型电子设备上。因此，在上述摄像模组10的基础上，本申请还提供一种电子设备，这种电子设备可以具体为手机、平板电脑、车载监控，均属于便携性强的小型设备，上述摄像模组10安装于设备本体上，以实现这些电子设备的摄像功能。以图19所示的手机100为例，手机100具有手机本体20，上述摄像模组10安装于手机本体20的背面，相当于手机10的后视摄像结构，用于实现后视摄像功能。
显然，本领域的技术人员可以对本申请实施例进行各种改动和变型而不脱离本申请实施例的范围。这样，倘若本申请实施例的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
