一种摄像头模组、摄像机以及移动终端
本申请要求于2019年6月6日提交中国专利局，申请号为201910491991.0、发明名称为“一种摄像头模组、摄像机以及移动终端”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
本申请涉及通信技术领域，具体涉及一种摄像头模组、摄像机以及移动终端。
背景技术
现有的智能设备上的摄像模组基本上都是通过马达机构带动镜头运动来实现自动对焦、变焦以及防抖，但是马达载体带动镜头进行运动需要一定的运动行程，因此在智能设备中需要为镜头的运动留出预留空间。以智能手机为例，随着智能手机越做越薄，手机中能够留给摄像模组的可利用空间越来越小，而马达载体需要磁石驱动线圈产生一定的推力才能够带动镜头实现纵向运动，其中，磁石在马达内部占据较大的体积，而且为了推力能够达到一定值，磁石的体积很难再减小，因此，需要在不减小磁石体积的前提下，改善马达结构，减小马达的体积，进而减小手机摄像模组的体积。
形状记忆合金(shape memory alloy，SMA)升温后能够消除在较低温度下发生的形变，恢复其变形前的原始形状，因而可通过SMA线驱动的马达驱动镜头进行运动。SMA线相对于传统的马达而言具有更小的体积，能够有效降低模组的整体尺寸，利于模组的小型化发展。但是由于马达线路板一般设置在马达的内部，而马达一般位于图像传感器的上方，马达线路板与距离图像传感器很近，当SMA线被通以脉冲宽度调制(pulse width modulation，PWM)驱动信号后对图像传感器产生电磁干扰，拍出来的照片上会出现条纹噪声，因此设计一种能够降低条纹噪声的摄像模组亟待解决。

目前，在手机拍摄过程中有时拍出的照片会发虚，即拍摄出来的画面不够清晰，甚至发生重影或模糊的情况。这些原因，除了偶尔的失焦(即相机未能正常对焦)以外，很大程度上是因为拍摄景物曝光时发生微小抖动所致。一般而言，在手持条件下经常会发生这种轻微的抖动的现象，由此会引发摄像装置的镜头偏离，使得图像传感器捕获到的图像质量产生劣化。故近年来对防抖技术功能开发需求相对较大。在此背景下，光学防抖(Optical Image Stabilization，OIS)功能的提案也随之增多，其主要功能是控制镜头相对于图像传感器移动而将手抖造成的图像偏移抵消补偿掉。一般OIS马达的制动器件包括音圈马达(voice coil motor，VCM)技术和形状记忆合金(shape memory alloy，SMA)技术。但是音圈马达在手机设计尺寸的限制下没有足够大的力来推动较大和较重的镜头。此外，智能手机制造商正朝着两个或更多的摄像头来增强图像功能，例如：景深功能(Bokeh)，Zoom应用和3D成像等。但因为音圈马达具有磁铁，两个音圈马达之间会有磁干扰所以不能靠得太近，进而影响了手机设计尺寸。所以SMA技术的优势得以发挥，目前SMA技术已应用在智能手机摄像头产业，如SMA AF(自动对焦)和SMA OIS(光学防抖)。其原理是用电流来加热SMA丝从马氏体变换成奥氏体状态，和靠自然冷却从奥氏体状态返回马氏体。从节省驱动功耗和方便检测SMA丝电阻的角度出发，SMA技术驱动的马达(以下简称SMA马达)最好采用脉冲宽度调制(pulse width modulation，PWM)信号驱动。当SMA马达及其走线距离图像传感器和模拟电源很近时，PWM信号的电磁辐射导致拍照条纹干扰，所以图像上会出现条纹噪声。这种条纹噪声在后期的图像处理上很难被过滤掉。所以SMA马达的PWM条纹噪声问题一直以来就是制约和限制SMA马达大规模商用的关键问题。
为了解决上述技术问题，本申请提供一种摄像头模组，解决电磁干扰导致拍照具有条纹噪声的问题。
图1是本申请实施例提供的摄像头模组的一种结构示意图。

在一种具体的实施方式中，镜头10中可以包括多个镜片(凹、凸透镜)，即通过多个镜片组合成像，马达40可以驱动镜头10做变焦运动，自动对焦运动或者光学防抖运动，具体的，马达40可以包括自动对焦(auto focus，AF)马达或者光学防抖(optical image stabilization，OIS)马达。其中，AF马达，用于调整镜头位置拍摄不同距离物体，OIS马达，用于调整镜头位置，使拍摄物体不会因为例如用户手抖动等原因造成图像模糊。换句话说，本申请实施例提到的镜头组件可以具有自动对焦功能、自动变焦功能以及光学防抖功能中的一种或几种。

需要说明的是，马达线路板30为软性线路板时，为了使马达线路板30不被轻易改变形状，还可以增加固定板，该固定板具有通光孔，固定板也可以称为补强板，该补强板与马达线路板贴合，使得马达线路板30保持固定的形状，该补强板还可以是屏蔽板。还需要说明的是，马达线路板30与支撑结构的固定连接方式不限定，比如可以采用焊接的方式固定连接，该焊接可以为激光焊接或者为其他焊接方式，本申请实施例对此不做限定,也可以是通过例如螺丝、螺栓等连接件可拆卸连接的，也可以是通过例如铰接件活动连接在一起的，或者可以将马达线路板30粘接在支撑结构，其中，该黏接可以为胶水黏接或者其他材料的黏接，本申请实施例对此不做限定。
马达40的致动器可以包括形状记忆合金(shape memory alloy，SMA)驱动44或者可以包括压电驱动。马达为SMA驱动的马达时，SMA驱动的马达包括活动件41、固定件43、镜头支架以及SMA丝线44，镜头支架一端固定于固定件43，另一端用于支撑活动件41，活动件41设有通光孔，活动件41用于安装镜头20，SMA丝线44的一端与固定件43连接，SMA丝线44的另一端与活动件41连接，固定件43包括底座以及定位部件，底座具有通光孔，底座位于镜头组件的像侧，定位部件一端固定于底座，另一端固定于马达线路板，马达线路板和马达之间有容纳空间，容纳空间用于容纳马达线路板上的电子器件。马达为压电驱动的马达，马达包括活动件41、固定件43、镜头支架42以及压电致动器，镜头支架一端固定于固定件43，另一端用于支撑活动件41，活动件41设有通光孔，活动件41用于安装镜头20，压电致动器包括压电片和谐振子，压电片固定在谐振子上，谐振子的一端与固定件43固定连接，另一端与活动件41接触连接，或者，谐振子的一端与固定件43接触连接，另一端与活动件41固定连接，固定件43包括底座以及定位部件，底座具有通光孔，底座位于镜头组件的像侧，定位部件一端固定于底座，另一端固定于马达线路板30，马达线路板30和马达40之间有容纳空间，容纳空间用于容纳马达线路板上30的电子器件。
具体的，致动器44可以通过焊接的方式与固定件43连接，或者致动器44可以通过螺栓的方式与固定件43连接，或者致动器可以通过卡爪45与固定件43进行连接，示例性的，以SMA马达为例，以致动器44通过卡爪45与固定件43进行连接为例进行具体的说明。具体的，图11和图12分别示出了一种马达固定件43的结构示意图。如图11所示，马达固定件43包括导电引脚431，具体的，马达线路板30与马达固定件43的导电引脚431电连接，马达线路板30与马达固定件43的导电引脚431电连接的方式可以包括马达线路板30与导电引脚431采用焊接的方式电连接，或者马达线路板30与导电引脚431采用导电 胶的方式电连接。如图13所示，为马达线路板30在马达上方时，马达的固定件43与马达线路板30的连接示意图，如图13中的A所示，卡爪45与致动器44连接，且卡爪45与马达固定件43的导电引脚431电连接。或者，如图12所示为另一种马达固定件43的结构示意图，在图12所示的结构中马达固定件43也可以不包括图11中所示的导电引脚431，此时，致动器44与马达线路板30的连接不再通过马达固定件43，具体的，如图14中的A所示，马达线路板30在马达40上方时，马达线路板30直接与卡爪45电连接，卡爪45与致动器44连接。当马达线路板30在马达40的侧面时，如图15所示，给出了一种马达线路板30在马达的侧方时的结构示意图，马达线路板30与马达40之间的连接方式可以参考马达线路板30在马达41的上方时进行理解，此处不再重复赘述。
马达线路板30与镜头组件信号连接，马达线路板30具有伸出壳体20的端部，马达线路板30通过该端部与电路板50信号连接。该电路板50可以为印制电路板(printed circuit board，PCB)、柔性线路板(flexible printed circuit，FPC)，也可以为其他类型的电路板，本实施例对此不做限定。在本申请实施例中，“信号连接”和“电连接”经常交替使用，本领域技术人员应当理解，在不特意强调二者的区别之时，二者表示相同的意思。
马达线路板30被电路板50通电后向镜头组件传输脉冲宽度调制(pulse width modulation，PWM)信号，PWM信号对图像传感器60的电磁干扰强度与马达线路板30和图像传感器60的距离负相关。图像传感器60芯片可以安装在电路板50上，图像传感器60芯片也可以简称为图像传感器60，图像传感器60与电路板50采用电连接。需要说明的是，还可以采用注塑封装工艺，对图像传感器进行位置的固定。具体地，可以通过高温注塑成形技术将熔融的环氧树脂注入模具中。从而可以图像传感器60包裹起来。形成塑封模块，并实现对图像传感器的位置进行固定。塑封模块中及图像传感器的焊端均会露出在塑封模块的有源面上。
在本申请实施例中，马达线路板30与电路板50电连通，马达线路板30在远离图像传感器60的一侧，以此增加了马达线路板30的PWM信号与图像传感器60之间的物理距离，从而降低PWM条纹噪声。
