技术领域
本申请属于通信设备技术领域，具体涉及一种电子设备及其摄像头模组。
背景技术
随着科技的进步，手机等电子设备在人们的生产生活中占据重要作用，且电子设备通常均配设有摄像头，以便于用户进行拍摄工作。在用户采用手持的方式进行拍摄的过程中，容易因用户抖动而造成拍摄的图像或视频出现模糊或重影等情况。相关技术中摄像头模组上通常配设有光学防抖组件，以提升拍摄的图像和视频的清晰度，但是，相关技术中光学防抖组件通常只能修正摄像头因在XYZ三维方向上产生移动引起的图像模糊的情况，而不能解决因摄像头绕自身光轴转动引起的图像拖影现象。
发明内容
本申请公开一种电子设备及其摄像头模组，能够解决目前因摄像头绕自身光轴转动引起的图像拖影现象的问题。
为了解决上述问题，本申请实施例是这样实现地：
第一方面，本申请实施例公开了一种摄像头模组，其包括镜头组件、模组支架、第一限位件、第一可变形件和第二可变形件，所述镜头组件和所述模组支架可转动连接，所述第一限位件固定于所述镜头组件或所述模组支架，所述第一可变形件和所述第二可变形件均为电致变形件，所述第一可变形件设置于所述第一限位件的一侧，所述第二可变形件设置于所述第一限位件的另一侧，
在所述镜头组件相对于所述模组支架沿第一方向转动的情况下，所述第一可变形件可变形，以检测所述镜头组件相对于所述模组支架的第一转动角度；在所述镜头组件相对于所述模组支架沿第二方向转动的情况下，所述第二可变形件可变形，以检测所述镜头组件相对于所述模组支架的第二转动角度，所述第二方向为所述第一方向的反方向。
第二方面，本申请实施例公开了一种电子设备，包括上述摄像头模组。
本申请公开一种摄像头模组，其包括镜头组件、模组支架、第一限位件、第一可变形 件和第二可变形件，第一限位件与镜头组件或模组支架相对固定，第一可变形件和第二可变形件均为电致变形件，且二者分别设置在第一限位件的相背两侧。在摄像头模组抖动而绕自身光轴方向转动时，会造成镜头组件和模组支架沿绕镜头组件的光轴方向相对转动，进而使第一限位件挤压第一可变形件(或第二可变形件)，使第一可变形件(或第二可变形件)变形，根据第一可变形件(或第二可变形件)的变形量，可以得到镜头组件和模组支架相对转动的角度大小；根据前述相对转动角度的大小，可以向第一可变形件(或第二可变形件)中通入预设大小的电压，进而使第一可变形件(或第二可变形件)驱动镜头组件和模组支架反向转动，使镜头组件和模组支架复位。
综上，在上述摄像头模组的工作过程中，如果摄像头模组因抖动而造成镜头组件相对取景区域转动的情况，摄像头模组可以对转动角度进行检测，且通入对应值的电压，驱动镜头组件反向运动，补偿因摄像头模组转动而产生的拖影现象，使镜头组件与取景区域的相对位置(或相对角度)保持不变，防止因摄像头模组转动而引发图像拖影，使摄像头的成像质量较高。

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和图2所示，本申请公开一种摄像头模组，其包括镜头组件110、模组支架(图中未示出)、第一限位件210、第一可变形件410和第二可变形件420。当然，摄像头模组中还可以设置有如感光芯片120等其他部件，感光芯片120可以设置在镜头组件110背离入光侧的一侧。
其中，镜头组件110可以包括至少一个透镜，摄像头模组之外的光线经镜头组件110入射至摄像头模组之内。模组支架为镜头模组的安装基础，且模组支架可以为镜头组件110提供一定的防护作用。模组支架可以采用金属或塑料等材料制成，其形状和具体结构形式有多种，例如，模组支架可以为圆筒状结构，模组支架围绕设置在镜头组件110之外，且使镜头组件110的底部和至少一部分侧部均可以被模组支架所包围，提升摄像头模组的使用寿命。
镜头组件110与模组支架之间可转动连接，具体地，镜头组件110和模组支架之间可以设置有转轴，转轴沿镜头组件110的光轴延伸，这可以保证镜头组件110能够相对模组支架绕镜头组件110的光轴转动。当然，镜头组件110和模组支架之间还可以通过其他连接件连接，使镜头组件110与模组支架之间能够形成转动连接关系，考虑文本简洁，此处不再一一举例。
第一限位件210可以为板状结构，亦可以为块状结构，对此，本文不作限定，当然，第一限位件210需具有满足需求的结构强度，从而保证第一限位件210能够为第一可变形件410和第二可变形件420提供限位作用。具体地，第一限位件210可以采用塑料或金属等材料制成。并且，第一限位件210可以通过插接、粘接或连接件连接等方式固定在镜头组件110或模组支架上。
为了保证第一限位件210可以正常提供限位功能，需要使第一限位件210设置在镜头组件110和模组支架之间。例如，第一限位件210可以固定在镜头组件110上，则第一限位件210可以固定在镜头组件110背离入光侧的一侧，也即镜头组件110的底部与模组支架之 间；或者，第一限位件210还可以固定在镜头组件110的侧壁之外，模组支架围绕设置在镜头组件110的侧壁之外，亦可以保证第一限位件210能够位于镜头组件110和模组支架之间。
第一可变形件410和第二可变形件420的结构可以相同，亦可以不同。可选地，二者可以为长条形结构，或者，二者还可以为弧形结构。第一可变形件410和第二可变形件420均为电致变形件，也即，第一可变形件410和第二可变形件420均采用电致变形材料制成，电致变形材料具体可以为压电材料或离子交换聚合金属材料等，这类材料在通电的情况下，可以产生形变，对应地，电致变形材料的形状发生变化的情况下，可以产生电压，本申请利用这种材料的上述原理对镜头组件110和模组支架之间的相对转动情况进行检测，且利用上述材料驱动镜头组件110和模组支架相对运动，以使镜头组件110和模组支架恢复至初始状态，达到防抖的目的。
第一可变形件410设置在第一限位件210的一侧，第二可变形件420设置在第一限位件210的另一侧，也就是说，第一可变形件410和第二可变形件420分别设置在第一限位件210的相背两侧。进而，在镜头组件110和模组支架相对转动的过程中，第一限位件210能够相对模组支架(或镜头组件110)转动，从而使第一限位件210能够接触并挤压第一可变形件410或第二可变形件420。
在镜头组件110相对于模组支架沿第一方向转动的情况下，第一可变形件410能够产生形变，以检测镜头组件110相对于模组支架的第一转动角度；在镜头组件110相对于模组支架沿第二方向转动的情况下，第二可变形件420能够产生形变，以检测镜头组件110相对于模组支架的第二转动角度。其中，第二方向为第一方向的反方向，也即，第一可变形件410和第二可变形件420能够分别检测镜头组件110相对于模组支架沿不同方向转动的角度，根据电压的来源，即可确定镜头组件110和模组支架的相对转动方向。
如上所述，第一限位件210可以固定在镜头组件110或模组支架上，例如，第一限位件210可以固定在镜头组件110上，可选地，第一可变形件410和第二可变形件420均可以安装在模组支架上。在上述实施例中，当镜头组件110和模组支架沿第一方向相对转动的过程中，第一限位件210和第一可变形件410亦可以相对运动，在第一限位件210与第一可变形件410接触后继续转动的过程中，第一限位件210可以向第一可变形件410施加 压力，使第一可变形件410的形状发生改变，进而可以使第一可变形件410产生电压，根据第一可变形件410产生的电压的大小，即可获取第一可变形件410的变形量，进而可以得到第一限位件210和第一可变形件410之间的相对运动角度，也即镜头组件110和模组支架之间沿第一方向的相对转动角度。
对应地，在镜头组件110和模组支架沿第二方向相对转动的情况下，则第一限位件210能够接触并挤压第二可变形件420，根据第二可变形件420产生的电压大小，亦可以得到镜头组件110和模组支架在第二方向上相对转动的角度值。需要说明的是，根据第一可变形件410(或第二可变形件420)的形状和材质等参数，且基于第一可变形件410(或第二可变形件420)产生的具体电压值，可以得到第一可变形件410(或第二可变形件420)的变形量，进而，根据前述变形量，结合第一限位件210和第一可变形件410(或第二可变形件420)之间的初始位置，即可得到第一限位件210和第一可变形件410(或第二可变形件420)之间的相对转动角度，进而得到镜头组件110和模组支架沿第一方向(或第二方向)的相对转动角度。
并且，根据上述测得的镜头组件110和模组支架沿第一方向(或第二方向)相对转动的角度之后，可以向第一可变形件410(或第二可变形件420)通入预设电压，使第一可变形件410(或第二可变形件420)在电压的作用下产生相应地变形量，进而使第一可变形件410通过自主变形，驱动第一限位件210转动，从而带动镜头组件110和模组支架沿第二方向(或第一方向)转动，使镜头组件110和模组支架之间恢复初始状态，实现防抖目的。
具体地，上述摄像头模组或包含该摄像头模组的电子设备中，可以设有电压处理组件300，如图3所示，其可以与电源连接，电压处理组件300具体可以包括控制器、电压检测器和电压输出器。如图3所示，第一可变形件410和第二可变形件420的相背两端均可以通过导线等连接结构与电压处理组件300电性连接，在第一可变形件410(或第二可变形件420)受挤压的情况下，其产生的电压可以通过导线传输至电压处理组件300。其中，电压检测器可以对产生的电压进行检测，根据预设条件可以确定第一可变形件410(或第二可变形件420)的变形量，控制器可以根据前述变形量确定镜头组件110和模组支架之间的相对转动角度，从而根据前述转动角度控制电压输出器输出对应大小的电压，使第一可变形件410(或第二可变形件420)主动变形，驱动镜头组件110和模组支架相对转动，实现复位。
本申请公开一种摄像头模组，其包括镜头组件110、模组支架、第一限位件210、第一可变形件410和第二可变形件420，第一限位件210与镜头组件110或模组支架相对固定，第一可变形件410和第二可变形件420均为电致变形件，且二者分别设置在第一限位件210的相背两侧。在摄像头模组抖动而绕自身光轴方向转动时，会造成镜头组件110和模组支架沿绕镜头组件110的光轴方向相对转动，进而使第一限位件210挤压第一可变形件410(或第二可变形件420)，使第一可变形件410(或第二可变形件420)变形，根据第一可变形件410(或第二可变形件420)的变形量，可以得到镜头组件110和模组支架相对转动的角度大小；根据前述相对转动角度的大小，可以向第一可变形件410(或第二可变形件420)中通入预设大小的电压，进而使第一可变形件410(或第二可变形件420)驱动镜头组件110和模组支架反向转动，使镜头组件110和模组支架复位。
综上，在上述摄像头模组的工作过程中，如果摄像头模组因抖动而造成镜头组件110相对取景区域转动的情况，摄像头模组可以对转动角度进行检测，且通入对应值的电压，驱动镜头组件110反向运动，补偿因摄像头模组转动而产生的拖影现象，使镜头组件110与取景区域的相对位置(或相对角度)保持不变，防止因摄像头模组转动而引发图像拖影，使摄像头的成像质量较高。
如上所述，在第一限位件210固定于镜头组件110上的情况下，可以使第一可变形件410和第二可变形件420均固定在模组支架上，保证第一可变形件410和第二可变形件420能够正常提供角度检测和复位驱动的作用。为了提升摄像头模组的调节精度，可以使第一可变形件410背离第一限位件210的一端与模组支架固定，对应地，可以使第二可变形件420背离第一限位件210的一端与模组支架固定。在这种情况下，使得第一可变形件410和第二可变形中的全部结构均能够产生变形，以实现角度检测，且可以使二者的全部结构均能够在通电的情况下变形，以实现驱动复位，这可以使第一可变形件410和第二可变形件420的利用率达到最大化，还可以在一定程度上提升对镜头组件110的检测和调节精度，提升防抖效果。
在本申请的另一实施例中，可选地，如图1和图2所示，摄像头模组还包括第二限位件220和第三限位件230，第二限位件220设置在第一限位件210的一侧，第三限位件230设置在第一限位件210的另一侧。也即，第二限位件220和第三限位件230分别设置在第 一限位件210的相背两侧。具体地，第二限位件220和第三限位件230的结构可以与第一限位件210相似，二者均可以为板状或块状等能够提供限位作用的结构。并且，第二限位件220和第三限位件230也均可以采用塑料或金属等硬质材料制成，从而保证第二限位件220和第三限位件230均能够提供稳定可靠的限位作用。
镜头组件110和模组支架中的一者与第一限位件210固定连接，另一者与第二限位件220和第三限位件230连接，第一可变形件410夹持在第二限位件220和第一限位件210之间，第二可变形件420夹持在第三限位件230和第一限位件210之间。也就是说，如图2所示，第二限位件220、第一可变形件410、第一限位件210、第二可变形件420、第三限位件230依次排布。
在上述技术方案中，当镜头组件110和模组支架沿第一方向相对转动的过程中，第一限位件210和第二限位件220能够相对转动，具体为相互靠近，以挤压位于二者之间的第一可变形件410，根据第一可变形件410的变形量可以确定镜头组件110和模组支架之间沿第一方向相对转动的角度，之后，根据测得的前述角度，可以向第一可变形件410通入预设大小的电压，使第一可变形件410主动变形，驱动第一限位件210和第二限位件220相对运动，使镜头组件110和模组支架沿第二方向相对转动，进而使镜头组件110复位，实现防抖目的。当然，在上述过程中，第三限位件230亦能够相对第一限位件210转动，但由于前述二者之间的相对转动过程不涉及上述角度检测和复位驱动过程，考虑文本简洁，此处不再展开介绍。
对应地，在镜头组件110和模组支架沿第二方向相对转动的过程中，则第一限位件210和第三限位件230相对转动，具体为相互靠近，以挤压位于二者之间的第二可变形件420，第二可变形件420的检测过程和驱动过程与第一可变形件410类似，其可以驱动镜头组件110和模组支架沿第一方向复位转动，使镜头组件110和模组支架恢复至初始位置。
在通过第二限位件220和第三限位件230对第一可变形件410和第二可变形件420的位置进行限制的情况下，可以使第一可变形件410和第二可变形件420均不与镜头组件110和模组支架连接，而仅借助第一限位件210、第二限位件220和第三限位件230，对第一可变形件410和第二可变形件420进行限位，从而防止因第一可变形件410和第二可变形件420受连接关系的限制，对二者在“变形-产电”的交互过程中的检测精度和变形精度产生不 利影响，以进一步提升对镜头组件110的转动角度的检测精度，也可以提升对镜头组件110的驱动精度。另外，上述实施例中，第一可变形件410和第二可变形件420的安装难度也相对较小。
可选地，第一可变形件410和第一限位件210的接触点与镜头组件110的光轴之间的第一间距，等于第一可变形件410和所述第二限位件220的接触点与所述镜头组件110的光轴之间的第二间距。也就是说，第一可变形件410与第一限位件210的作用点与镜头组件110的中心的距离，等于第一可变形件410与第二限位件220的作用点与镜头组件110的中心的距离，进而在第一可变形件410受挤压而变形或通电时主动产生变形时，使第一限位件210和第二限位件220与第一可变形件410之间的相互作用效果相同。
对应地，可以使第二可变形件420和所述第一限位件210的接触点与所述镜头组件110的光轴之间的第三间距，等于所述第二可变形件420和所述第三限位件230的接触点与所述镜头组件110的光轴之间的第四间距，从而使第一限位件210和第三限位件230与第二可变形件420之间的作用效果也基本相同。
具体地，如上所述，第一可变形件410可以为条形结构件等，通过使第一可变形件410的延伸方向垂直于第一可变形件410的中点与镜头组件110的光轴的连线，可以使第一可变形件410的相背两端与镜头组件110的光轴之间的间距相等或基本相等。
第一限位件210和第二限位件220与第一可变形件410之间均可以形成点接触，亦可以形成面接触。在第一限位件210和第二限位件220均与第一可变形件410形成面接触的情况下，上述接触点可以为互相对应的接触点。例如，上述互相对应的接触点可以包括：第一可变形件410的一端端面的中心与第一限位件210的第一接触点，与第一可变形件410的另一端端面的中心与第二限位件220的第二接触点。由于第二可变形件420与第一可变形件410的结构类似，二者的设置方式亦可以基本相同，此处不再重复。
进一步地，可以使所述第一限位件210和所述第二限位件220均具有限位平面，也即，第一限位件210和第二限位件220均通过平面结构与第一可变形件410相互配合，这可以在一定程度上提升对第一可变形件410的限位效果。可选地，上述两个限位平面的交线为所述镜头组件110的光轴所在的直线，也就是说，第一限位件210的限位平面和第二限位件220的限位平面相交，且均过镜头组件110的光轴，或者说，镜头组件110的光轴所在的 直线同时位于第一限位件210和第二限位件220的限位平面上。
在第一可变形件410通电的情况下，第一可变形件410变形，且通过自身分别向第一限位件210和第二限位件220施加第一驱动力和第二驱动力，通过采用上述技术方案，可以使第一驱动力的方向基本垂直于第一限位件210的限位平面，且使第二驱动力的方向基本垂直于第二限位件220的限位平面，使第一驱动力和第二驱动力基本没有其他作用效果，而仅能作用于第一限位件210和第二限位件220，以使第一限位件210和第二限位件220相对转动，这可以减少驱动力的浪费，提升驱动有效率，降低功耗。
另外，在采用上述技术方案的情况下，可以使第一限位件210和第二限位件220之间的相对转动量基本可以全部作用至第一可变形件410，以使第一可变形件410产生压缩变形，这可以使第一可变形件410测得的镜头组件110和模组支架之间的转动角度的值更精确。
对应地，通过使所述第一限位件210和所述第三限位件230均具有限位平面，且使两个所述限位平面的交线为所述镜头组件110的光轴所在的直线，亦可以提升第二可变形件420的驱动有效率，且降低功耗，且可以提升第二可变形件420对镜头组件110和模组支架之间的相对转动角度的测量精度。
可选地，第一可变形件410和第二可变形件420均可以为弧形结构件，这可以进一步提升二者与第一限位件210之间的作用效果。在本申请的另一实施例中，第一可变形件410和第二可变形件420均可以为球形结构件，这可以使第一可变形件410和第二可变形件420能够满足上述实施例的需求，且可以降低第一可变形件410和第二可变形件420的加工和安装难度。
如上所述，第一限位件210可以固定在镜头模组上，亦可以固定在模组支架上。可选地，第一限位件210固定在镜头组件110上，以减少连接在镜头组件110上的部件的数量，降低镜头组件110的转动难度。
如上所述，第一限位件210可以设置在镜头组件110的底部，在本申请的另一实施例中，如图2所示，第一限位件210设置于镜头组件110的侧壁之外。在这种情况下，镜头组件110产生较小的转动动作，即可使第一限位件210随镜头组件110运动，从而使第一限位件210的感应灵敏度更高，提升摄像模组的防抖性能。其中，镜头组件110的侧壁环绕镜头组件110的光轴设置，对应地，镜头组件110的底部为垂直于镜头组件110的光轴的结 构。
基于上述实施例，在摄像头模组设置有第二限位件220和第三限位件230的情况下，则第二限位件220和第三限位件230亦可以设置在镜头组件110的侧壁之外，在第一限位件210与镜头组件110连接的情况下，第二限位件220和第三限位件230则可以均与模组支架固定连接。
为了保证第一可变形件410不会在第一限位件210和第二限位件220之间向远离镜头组件110的方向运动，也即，防止第一可变形件410沿镜头组件110的轴向远离镜头组件110，可以使第一限位件210和第二限位件220背离镜头组件110的一侧可以相互靠近，从而将第一可变形件410夹持在第一限位件210、第二限位件220和镜头组件110之间。
但是，如上所述，为了提升摄像头模组的性能，可以使第一限位件210和第二限位件220的限位平面均过镜头组件110的光轴所在的直线，在这种情况下，第一限位件210和第二限位件220之间越靠近镜头组件110的位置之间的间距越小，而二者之间越远离镜头组件110的位置之间的间距则越大，从而使第一限位件210和第二限位件220形成扩口状结构件，这使得移靠第一限位件210和第二限位件220无法为第一可变形件410提供限位作用。相应地，第二可变形件420亦存在无法被第一限位件210和第三限位件230限位的问题。
基于此，可选地，如图1和图2所示，摄像头模组还可以包括弹性限位件240，弹性限位件240连接在第二限位件220和第三限位件230背离镜头组件110的一侧，第一可变形件410和第二可变形件420均限位设置于弹性限位件240和镜头组件110的侧壁之间。在这种情况下，可以借助弹性限位件240对第一可变形件410和第二可变形件420的位置进行限制，防止因第一可变形件410和第二可变形件420向远离镜头组件110的方向运动而无法正常提供角度检测和复位驱动作用。
弹性限位件240具体可以采用具有一定弹性能力的材料制成，以在第一可变形件410受第一限位件210和第二限位件220的挤压作用时，通过使弹性限位件240产生弹性形变，为第一可变形件410提供让位空间，保证第一可变形件410受挤压能够正常变形。对应地，在第二可变形件420受挤压而变形的过程中，第二可变形件420亦可以通过挤压弹性限位件240的方式，保证自身能够正常产生形变。
当然，为了保证第一可变形件410和第二可变形件420均可以稳定地与镜头组件110配合，除了在第一限位件210背离镜头组件110的一侧设置弹性限位件240之外，如图1和图2所示，还可以在第一限位件210的另外两侧分别设置限位结构250，使第一可变形件410和第二可变形件420可以被封装限位在第二限位件220、弹性限位件240、第三限位件230、镜头组件110和前述两个限位结构250之间。
可选地，第一限位件210的数量为多个，各第一限位件210的一侧均设有第一可变形件410，另一侧均设有第二可变形件420。在这种情况下，在镜头组件110相对于模组支架沿第一方向转动时，可以通过多个第一可变形件410同时对转动角度进行检测，以进一步提升角度检测精度。并且，可以通过多个第一可变形件410一并驱动镜头组件110相对模组支架转动，提升驱动可靠性。对应地，在镜头组件110相对于模组支架沿第二方向转动时，可以通过多个第二可变形件420对转动角度进行测量，提升测量和调节精度。
在第一限位件210、第一可变形件410和第二可变形件420的数量均设置有多个的情况下，亦可以设置多个第二限位件220和多个第三限位件230，且使多个第二限位件220和多个第三限位件230一一对应地与多个第一限位件210配合，进一步提升摄像头模组的调节精度。
可选地，多个第一限位件210围绕镜头组件110的光轴均匀且间隔分布，在这种情况下，使得镜头组件110上的各处均可以受到较为均匀的驱动作用力，防止镜头组件110在相对模组支架转动的过程中因受力偏斜而卡滞，提升摄像头模组的可靠性。第一限位件210的数量具体可以为三个、四个或更多个，这可以保证镜头组件110和模组支架之间形成的配合关系均较为可靠。
