图2示出了电子设备100内设有一个摄像模组1，应说明，在实际应用中，摄像模组1的数量不局限于为一个，摄像模组1的数量也可以为两个或大于两个。当摄像模组1的数量为多个时，多个摄像模组1可在X-Y平面内任意排布。例如，多个摄像模组1沿X轴方向排布，或者，多个摄像模组1沿Y轴方向排布。
此外，摄像模组1包括但不限于为自动对焦(Auto Focus，AF)模组、定焦(Fix Focus，FF)模组、广角摄像模组1、长焦摄像模组1、彩色摄像模组1或者黑白摄像模组1。电子设备100内的摄像模组1可以包括上述任一种摄像模组1，或者，包括上述其中两个或两个以上摄像模组1。当摄像模组1的数量为两个或者两个以上时，两个或者两个以上的摄像模组1可以集成为一个摄像组件。
参照图2所示，摄像模组1可以和电路板4电连接。电路板4例如为电子设备100内的主板，作为一种实施方式，摄像模组1可以通过电连接器与主板电连接。例如，摄像模组1设有电连接器的母座，主板设有电连接器的公座，通过将母座插接于公座，以实现摄像模组1与主板的电连接。其中，主板上例如设有处理器，通过处理器控制摄像模组1拍摄图像。当用户输入拍摄指令时，处理器接收拍摄指令，并根据拍摄指令控制摄像模组1对拍摄对象进行拍摄。
以下对本申请实施例的电子设备100中的摄像模组1进行详细介绍。
图3为本申请实施例提供的摄像模组的结构示意图；图4为图3的爆炸图。参照图3和图4所示，本实施例的摄像模组1包括壳体11、镜头13和图像传感器组件16。壳体11的一侧表面设有安装孔1111，壳体11内部中空，形成容纳空间，镜头13通过安装孔1111安装在壳体11上，且镜头13的部分位于壳体11内的容纳空间内，镜头13的另一部分暴露在壳体11外部；图像传感器组件16设于壳体11内，例如，图像传感器组件16设于壳体11的底部。
图5为图3的主视图；图6为图5中的A-A剖视图；图7为图5中的B-B剖视图。参照图6和图7所示，镜头13的入光侧位于壳体11外部，镜头13的出光侧位于壳体11内部。例如，镜头13的入光侧与电子设备后盖上的透光孔相对应，外部环境光线经过透光孔由镜头13的入光侧进入镜头13，镜头13例如由一个或多个层叠的透镜构成，镜头13的光轴穿过透镜的中心，透镜对入射光线进行聚光，汇聚后的光线从镜头13的出光侧射出。
图像传感器组件16位于镜头13的出光光路上，例如，图像传感器组件16位于镜头13的出光侧，且镜头13的光轴穿过图像传感器组件16的中心。从镜头13出射的光线进 入图像传感器组件16，通过图像传感器组件16的光电转换作用，将出射光线信号转换为电信号，以实现摄像模组1的成像功能。
结合图4所示，本实施例中，壳体11可以包括外框111和底板112，外框111和底板112共同围成壳体11的容纳空间。通过设置可拆卸的底板112，便于将摄像模组1的镜头13、图像传感器组件16及其他器件安装在壳体11内。其中，安装孔1111位于外框111与底板112相对的一侧表面，镜头13沿其光轴方向穿过安装孔1111安装于壳体11内，图像传感器组件16靠近底板112设置。
继续参照图6和图7，本实施例的摄像模组1还包括第一驱动组件14和第二驱动组件15，第一驱动组件14和第二驱动组件15设于壳体11内。具体的，第一驱动组件14用于驱动图像传感器组件16移动，例如，第一驱动组件14可驱动图像传感器组件16在垂直于镜头13的光轴方向上，在其自身所在的平面内平移或者旋转，以实现摄像模组1的防抖功能；第二驱动组件15用于驱动镜头13移动，例如，第二驱动组件15可驱动镜头13沿其自身的光轴方向移动，以实现摄像模组1的对焦功能。
本实施例的摄像模组1，壳体11内还设置有固定支架12，第一驱动组件14和第二驱动组件15通过固定支架12可活动的安装于壳体11内。图8为本申请实施例提供的摄像模组的内部结构示意图；图9为图8的爆炸图。参照图8和图9所示，固定支架12套设在镜头13外，固定支架12包括第一固定部121和第二固定部122，第二固定部122的一端连接在第一固定部121面向壳体11底部的一侧，第二固定部122的另一端支撑在壳体11的内底壁上。
第一固定部121位于镜头13的外侧，例如，第一固定部121为围设在镜头13外侧的环状部。图10为第一驱动组件和固定支架的组装示意图。参照图10所示，第一驱动组件14连接在第一固定部121朝向壳体11底板112的一侧表面，其中，第一驱动组件14的一部分固定在第一固定部121上，第一驱动组件14的另一部分可相对第一固定部121移动，图像传感器组件16与第一驱动组件14的可移动的部分连接，通过第一驱动组件14的可移动的部分带动图像传感器组件16移动。
在一种实施方式中，第一驱动组件14的可移动的部分，可在其自身所在的平面内平移或旋转，第一驱动组件14的该部分带动图像传感器组件16在其所在的平面内平移或旋转，通过图像传感器组件16的移动来补偿用户手部抖动产生的位移量，防止拍摄的图像出现模糊现象，提高图像的清晰度，提升摄像模组1拍摄的图像的品质。
结合图7所示，固定支架12通过第二固定部122支撑在壳体11的底板112上，第二固定部122限定出第一固定部121和底板112之间的空间。由于第一驱动组件14和图像传感器组件16依次连接在第一固定部121朝向底板112的表面上，因此，第一固定部121和底板112之间的空间至少用于容纳第一驱动组件14和图像传感器组件16。需要说明的是，第一固定部121和底板112之间的间距应大于第一驱动组件14和图像传感器组件16的整体高度，这样，图像传感器组件16与底板112之间具有间隙，底板112对图像传感器组件16的移动没有阻碍。
在一种具体实施方式中，第二固定部122可以包括多个间隔设置的支撑部1221，各支撑部1221均与第一固定部121朝向壳体11底部的一侧表面连接，第一驱动组件14和图像传感器组件16位于各支撑部1221围成的空间内。参照图9所示，以第一固定部121外缘 的轮廓为矩形结构为例，支撑部1221可以包括四个，四个支撑部1221分别位于第一固定部121的四个角部。
第二驱动组件15套设在镜头13外，例如，第二驱动组件15固定在镜头13的外壁上。第一固定部121靠近镜头13外侧壁的内缘固定有至少一个磁性件17，第二驱动组件15位于第一固定部121内缘的内侧，第二驱动组件15朝向磁性件17，磁性件17用于驱动第二驱动组件15移动，第二驱动组件15移动可带动镜头13移动。
具体的，第二驱动组件15可以产生磁场，且第二驱动组件15和磁性件17之间可以产生磁力，通过改变第二驱动组件15和磁性件17之间的磁力，驱动第二驱动组件15移动。示例性的，磁性件17驱动第二驱动组件15沿镜头13的光轴方向移动，第二驱动组件15带动镜头13沿光轴方向移动，以调整镜头13的焦距。
另外，第一固定部121的内缘可以固定有至少两个磁性件17，以两个磁性件17为例，该两个磁性件17可以设置于第一固定部121的相对两侧。通过两个磁性件17驱动第二驱动组件15移动，可增强磁性件17对第二驱动组件15的驱动力；且两个磁性件17相对设置，保证第二驱动组件15带动镜头13平稳移动，避免镜头13在移动过程中发生偏斜。
应说明，第一固定部121的内缘固定的磁性件17的数量还可以为三个、四个、五个、六个或者八个等，本实施例对此不做限制。其中，多个磁性件17可以沿第一固定部121的周向均匀间隔设置；或者，磁性件17的数量为偶数，多个磁性件17两两相对设置。
示例性的，摄像模组1的外壳例如可以为长方体形状，例如，外壳沿与镜头13的轴向垂直的方向的横截面形状为矩形。与壳体11的形状相匹配的，固定支架12的第一固定部121可以为矩形框结构，镜头13的部分穿设在矩形框围成的区域内。以第一固定部121的内缘设置有两两相对的两个或四个磁性件17为例，矩形框的内缘的轮廓可以为矩形；若第一固定部121的内缘设置有两两相对的六个或八个磁性件17，矩形框的内缘的轮廓相应可以为六边形或八边形。
需要说明的是，参照图9所示，固定支架12可以为一体成型件，第一固定部121和第二固定部122为一个整体，第二固定部122形成在第一固定部121朝向壳体11底部的一侧。
在其他实施例中，第一固定部121和第二固定部122也可以单独设计加工，第一固定部121和第二固定部122连接在一起构成固定支架12。例如，第一固定部121和第二固定部122之间粘接、焊接或通过螺栓、螺钉、铆钉等连接件连接。对此，第一固定部121可以为环状件，第二固定部122可以包括多个单独的支撑部1221；或者，第二固定部122包括一个环状部作为主体，该环状部与第一固定部121相匹配，环状部与第一固定部121贴合连接，各支撑部1221连接在环状部上。
本实施例中，通过设置固定支架12，固定支架12包括第一固定部121和第二固定部122，第二固定部122与第一固定部121连接并支撑在壳体11的底板112上。通过在第一固定部121朝向底板112的一侧表面连接第一驱动组件14，第一驱动组件14的固定部分连接在第一固定部121上，第一驱动组件14的可动部分与图像传感器组件16连接，第一驱动组件14带动图像传感器组件16移动；通过在第一固定部121的内缘固定磁性件17，磁性件17驱动套设在镜头13外壁上的第二驱动组件15移动，第二驱动组件15带动镜头13移动。这样，第一驱动组件14和驱动第二驱动组件15移动的磁性件17均连接在固定支架12上，简化了摄像模组1的结构，降低了摄像模组1的组装难度。另外，第一驱动 组件14和第二驱动组件15可同步制造完成并进行性能测试，可精准测试摄像模组1的防抖性能，提高了摄像模组1的可靠性。
图11为第一驱动组件的正视图；图12为第一驱动组件的后视图。参照图11和图12所示，本实施例中，第一驱动组件14包括固定件141、驱动件142和形状记忆合金线143，固定件141的一侧表面固定连接在第一固定部121朝向壳体11底板112的一侧表面上，驱动件142位于固定件141的另一侧，例如，驱动件142沿镜头13的光轴方向层叠在固定件141的下方，图像传感器组件16连接在驱动件142朝向壳体11底板112的一侧表面上。其中，驱动件142通过形状记忆合金线143与固定件141连接，利用形状记忆合金线143的特性使驱动件142相对固定件141产生位移，从而使驱动件142带动图像传感器组件16移动。
需要说明的是，形状记忆合金(Shape Memory Alloys，SMA)是一种在加热升温后能完全消除其在较低的温度下发生的变形，恢复其变形前原始形状的合金材料，即拥有"记忆"效应的合金。SMA为热弹性马氏体相变材料，其可在温度改变时产生相变，由此应力状态也发生变化。在低温状态下，SMA处于马氏体相状态；而温度升高时，SMA由马氏体相转化为奥氏体相，并产生变形收缩。
因此，可以在形状记忆合金线143(以下简称SMA线143)中通入电流，并利用电流的加热作用使SMA线143升温，从而实现SMA线143的收缩变形。而SMA线143中没有电流流过时，其可恢复至原状。这样，利用SMA线143在通电状态变化时的变形可驱动驱动件142移动。
具体的，SMA线143沿第一驱动组件14所在的平面延伸，SMA线143的一端与固定件141连接，SMA线143的另一端与驱动件142连接。例如，SMA线143沿第一驱动组件14的侧边延伸，SMA线143的两端分别延伸至第一驱动组件14的两端。在未通电状态下，SMA为伸长状态；而当SMA线143中通入电流后，SMA线143温度升高而收缩，由于SMA线143与固定件141连接的一端固定，因而，SMA线143与驱动件142连接的一端朝向SMA线143的另一端移动，由此，SMA线143收缩带动驱动件142移动。
参照图12所示，本实施例中，固定件141和驱动件142之间连接有至少两根SMA线143，不同SMA线143分别位于第一驱动组件14的不同侧，这样，不同SMA线143在通电状态下，在不同方位上产生收缩，可带动驱动件142在不同方位上产生位移。从而，通过对不同SMA线143中电流的大小和方向进行控制，可实现驱动件142在第一驱动组件14所在的平面内任意移动，例如，SMA线143驱动驱动件142相对固定件141平移或旋转。
以两根SMA线143为例，这两根SMA线143位于第一驱动组件14的不同侧，通过使两根SMA线143均向某一方向收缩或两根SMA线143向某一部位集中收缩，可带动驱动件142相对固定件141平移；通过使两根SMA线143向不同方向、不同部位收缩，可带动驱动件142相对固定件141旋转。
至于向SMA线143中通入电流，在一些实施方式中，固定件141和驱动件142均为导电件，通过将固定件141和驱动件142中的一者与外电路(例如电子设备中的电路板4)电连接，将电流引入SMA线143中。例如，当用户进行拍摄时，当电子设备检测到需要通过第一驱动组件14的移动来补偿用户手部的抖动时，电路板4向SMA线143中通入电 流，并且，根据需要补偿的移动量和移动方位，控制SMA线143中电流的大小和方向，SMA线143因通电升温而向相应方向产生一定的收缩量，以驱动驱动件142移动，驱动件142带动图像传感器组件16移动以补偿手部抖动。
在实际应用中，电子设备中通常还设置有加速传感器，通过加速传感器检测电子设备的移动方向及移动量。例如，加速传感器检测拍摄时用户手部抖动的方向及抖动量，加速传感器将该抖动信号传输至电路板4中的处理器，处理器根据该抖动信号确定图像传感器组件16需要补偿的移动方向及移动量，并控制不同SMA线143中电流的方向和大小，调节不同SMA线143的收缩方向和收缩量，从而控制驱动件142的移动方向和移动量，驱动件142带动图像传感器组件16移动，以补偿用户拍摄时手部抖动的干扰，改善图像的模糊现象，提升图像的质量。
另外，需要说明的是，固定件141和驱动件142上设有贯穿的出光孔144，出光孔144对应镜头13的出光侧，图像传感器组件16位于出光孔144下方，镜头13的出光侧射出的光线穿过出光孔144照射至图像传感器组件16。
结合图7所示，在一些实施例中，固定件141朝向驱动件142的一侧表面设有凸起部1411a，凸起部1411a朝向驱动件142凸起，驱动件142表面上对应凸起部1411a的部位与固定件141接触，驱动件142其他部位与固定件141之间具有缝隙。如此，驱动件142相对固定件141移动时，只有与凸起部1411a相对的部位与固定件141接触，减弱了固定件141对驱动件142移动的阻碍作用，保证驱动件142移动灵活。
固定件141上可以设置有至少两个凸起部1411a，这两个凸起部1411a相对设置，该两个凸起部1411a分别和驱动件142的相对两侧接触，这样，保证了驱动件142的平衡性，驱动件142能够带动图像传感器组件16平稳移动。另外，固定件141上设置的凸起部1411a的数量还可以为四个、六个或八个等，多个凸起部1411a可以两两相对设置，本实施例对此不做具体限制。
参照图11和图12所示，本实施例中，通过固定件141和驱动件142上的卡爪对SMA线143进行固定。具体的，固定件141上设有两组第一卡爪1413，两组第一卡爪1413相对设置，驱动件142上设有两组第二卡爪1421，两组第二卡爪1421相对设置，第一卡爪1413和第二卡爪1421间隔设置。这样，第一卡爪1413和第二卡爪1421相邻设置，SMA线143的一端连接在固定件141的第一卡爪1413上，SMA线143的另一端连接在驱动件142的第二卡爪1421上。
以第一驱动组件14的外轮廓为矩形为例，两组第一卡爪1413分别位于第一驱动组件14的两个相对的角部，两组第二卡爪1421分别位于第一驱动组件14的另外两个相对的角部，且，两组第一卡爪1413设在固定件141上，两组第二卡爪1421设在驱动件142上。其中，对于各SMA线143，SMA线143位于第一驱动组件14的侧边，SMA线143的一端与固定件141角部的第一卡爪1413连接，SMA线143的另一端与驱动件142角部的第二卡爪1421连接。
在一种实施方式中，第一驱动组件14可以包括两根SMA线143，两根SMA线143相邻设置或相对设置。
以两根SMA线143相邻设置为例，参照图12所示，将位于图中上侧的SMA线143定义为第一SMA线1431，将位于图中右侧的SMA线143定义为第二SMA线1432，第 一SMA线1431和第二SMA线1432的相邻的一端均连接在驱动件142的同一个第二卡爪1421上，第一SMA线1431的另一端及第二SMA线1432的另一端分别与固定件141的两个第一卡爪1413连接。其中，根据驱动件142需要补偿的位移量和位移方向，可以仅是第一SMA线1431和第二SMA线1432中的一者收缩，也可以是第一SMA线1431和第二SMA线1432均收缩。第一SMA线1431和第二SMA线1432均收缩时，两者的收缩量可以一致或者不一致。
应说明，第一驱动组件14中仅设置两根SMA线143，且两根SMA线143相邻设置时，由于两根SMA线143相邻的一端连接在同一个第一卡爪1413或同一个第二卡爪1421上，因此，可以在固定件141上仅设置一个第一卡爪1413，在驱动件142上设置两个第二卡爪1421；或者，在固定件141上设置两个第一卡爪1413，在驱动件142上仅设置一个第二卡爪1421。而为了便于两根SMA线143的设置，在固定件141上设置两个第一卡爪1413，在驱动件142上设置两个第二卡爪1421。
以两根SMA线143相对设置为例，继续参照图12，将位于图中下侧的SMA线143定义为第三SMA线1433，以第一驱动组件14中设有第一SMA线1431和第三SMA线1433为例，第一SMA线1431的两端分别与相邻的第一卡爪1413和第二卡爪1421连接，第三SMA线1433的两端分别与另外的第一卡爪1413和另外的第二卡爪1421连接。其中，根据驱动件142需要补偿的位移量和位移方向，可以仅是第一SMA线1431和第三SMA线1433中的一者收缩，也可以是第一SMA线1431和第三SMA线1433均收缩。第一SMA线1431和第三SMA线1433均收缩时，两者的收缩量可以一致或者不一致。
参照图12所示，在另一种实施方式中，第一驱动组件14可以包括四根SMA线143，以第一驱动组件14的外轮廓为矩形为例，第一驱动组件14的四侧均设有SMA线143。为此，每组第一卡爪1413的两侧均连接有SMA线143，每组第二卡爪1421的两侧同样均连接有SMA线143，以其中一组第一卡爪1413为例，该第一卡爪1413两侧连接的两根SMA线143分别与两侧的第二卡爪1421连接。其中，根据驱动件142需要补偿的位移量和位移方向，可以是四根SMA线143中的一根SMA线143收缩，或者，至少有两根SMA线143收缩。有两根以上SMA线143收缩时，不同SMA线143的收缩量可以一致或者不一致。
参照图11和图12所示，为便于在第一卡爪1413的两侧连接SMA线143，第一卡爪1413可以包括分隔设置的第一卡接部1413a和第二卡接部1413b，第一卡接部1413a和第二卡接部1413b均位于固定件141的同一个角部，并且，第一卡接部1413a和第二卡接部1413b分别对应固定件141相邻的两侧边。以图12中左上角的第一卡爪1413为例，将该第一卡爪1413的位于右上方位的部分定义为第一卡接部1413a，将该第一卡爪1413的位于左下方位的部分定义为第二卡接部1413b，第一卡接部1413a与位于上侧的SMA线143的一端连接，第二卡接部1413b与位于下侧的SMA线143的一端连接。
另外，与第一卡爪1413的第一卡接部1413a和第二卡接部1413b相应的，第二卡爪1421也可以包括两部分，例如，第二卡爪1421包括第一卡接端1421a和第二卡接端1421b，第一卡接端1421a和第二卡接端1421b分别与相邻两侧的SMA线143的一端连接。
参照图12所示，本实施例中，第一卡爪1413的第一卡接部1413a和第二卡接部1413b之间可以形成限位空间，该限位空间用于限定驱动件142的移动范围，例如，限定驱动件 142的平移距离范围或者旋转角度范围。在实际应用中，用户拍照时手部抖动的幅度往往较小，驱动件142需要的补偿的移动范围和偏转角度通常也较小，因而，可以将驱动件142的移动限制在一定范围内。这样，驱动件142在小范围内的移动更平稳，并且，可防止SMA线143过度伸缩或扭转，以保障SMA线143能够持久的维持良好的工作性能。
具体的，驱动件142上设有限位部1422，限位部1422与第一卡接部1413a和第二卡接部1413b之间的限位空间对应，限位部1422位于第一卡接部1413a和第二卡接部1413b之间的限位空间内，且限位部1422可在限位空间内移动，例如，限位部1422可以平移或旋转。示例性的，限位部1422可以为驱动件142边缘向外伸出的延伸部，该延伸部例如位于驱动件142的角部，该延伸部可以沿驱动件142的平面向驱动件142外伸出。
参照图12所示，作为一种具体实施方式，驱动件142在限位部1422周围设有镂空区域1423，该镂空区域1423可以减轻驱动件142的自重，提高驱动件142移动的灵活性；此外，该镂空区域1423可以由限位部1422向限位部1422两侧延伸，使限位部1422形及限位部1422两侧形成弯折的弹性臂，这样，驱动件142移动至限位部1422与第一卡接部1413a或第二卡接部1413b接触时，限位部1422依靠自身的形变继续沿原方向移动一定距离，增大了驱动件142的移动范围。
如前所述，驱动件142上的限位部1422可沿驱动件142所在平面向外伸出，而由于固定件141和驱动件142层叠设置，为了实现第一卡接部1413a和第二卡接部1413b对限位部1422的限位作用，参照图12所示，第一卡接部1413a和第二卡接部1413b可以均包括弯折部1413c，第一卡接部1413a和第二卡接部1413b均通过弯折部1413c连接在固定件141上，弯折部1413c向驱动件142弯折。通过弯折部1413c使第一卡接部1413a和第二卡接部1413b弯折至驱动件142所在的平面，这样，第一卡接部1413a和第二卡接部1413b均与限位部1422处于同一平面内，且限位部1422位于第一卡接部1413a和第二卡接部1413b之间的限位空间内，限位部1422可移动至与第一卡接部1413a或第二卡接部1413b抵接，以对限位部1422进行限位。
由于固定件141上的第一卡爪1413具有向驱动件142弯折的弯折部1413c，为了便于固定件141的加工与组装，在一些实施例中，固定件141可以包括基板1411和导电板1412，导电板1412固定在基板1411上共同构成固定件141。图13为本申请实施例提供的固定支架和固定件的基板1411的爆炸图。参照图9和图13所示，固定件141的基板1411的一侧表面固定连接在固定支架12上，例如，基板1411的一侧表面固定在第一固定部121朝向壳体11底板112的表面上，导电板1412固定在基板1411的另一侧表面上，固定件141的第一卡爪1413和第二卡爪1421均设在导电板1412上，SMA线143连接在导电板1412和驱动件142之间。
示例性的，固定件141的基板1411可以为平板状的金属件或塑料件，导电板1412可以为金属件，导电板1412可以焊接或粘贴在基板1411上，驱动件142为金属件。这样，可通过导电板1412或驱动件142和外部电路(例如电子设备的电路板4)电连接，向SMA线143中通入电流。其中，可以利用固定的导电板1412与外部电路电连接，例如，参见图11或图12，导电板1412上具有电连接端1412a，导电板1412的电连接端1412a通过柔性导线与电路板4电连接。如此，避免通过移动的驱动件142与外部电路电连接，以免对柔性导线造成损伤。
另外，参见图13，对于固定件141上设置的凸起部1411a，凸起部1411a可以设置在基板1411上，结合图11所示，导电板1412上对应凸起部1411a可以设有避让区域1412b，避让区域1412b用于避让凸起部1411a，以使凸起部1411a与驱动件142接触。另外，驱动件142相对固定件141移动时，通过避让区域1412b的边沿对凸起部1411a的止挡作用，可对驱动件142的移动进行限位。
在其他实施方式中，还可以通过在壳体11的底板112或壳体11内的其他部位设置限位结构，通过限位结构对图像传感器组件16的移动进行限位，从而，限制驱动件142的移动范围。
具体的，导电板1412可以包括多个，各导电板1412均固定在基板1411上，不同的第一卡爪1413可以位于不同的导电板1412上，例如，导电板1412包括两个，两个第一卡爪1413分别位于两个导电板1412上。示例性的，参见图11，固定件141可以包括四个导电板1412，各导电板1412上分别设置第一卡爪1413的第一卡接部1413a或第二卡接部1413b，四个导电板1412共同构成两个第一卡爪1413，这样，便于加工第一卡爪1413。其中，每个导电板1412上可以均具有电连接端1412a，每个导电板1412均与外部电路电连接。
参照图8所示，本实施例中，第二驱动组件15包括支承座151和第二驱动线圈152。支承座151套设在镜头13的外壁上，用于对镜头13进行支撑。示例性的，镜头13的外壁可以设有外螺纹，支承座151的内壁设有内螺纹，支承座151与镜头13的外壁螺纹连接。第二驱动线圈152套设在支承座151的外壁上，第二驱动线圈152与支承座151固定连接。
图14为图8中去除固定支架之后的结构示意图。参照图14所示，第一固定部121内缘固定的磁性件17朝向第二驱动组件15，具体的，磁性件17朝向第二驱动线圈152，第二驱动线圈152可以和电子设备中的电路板4电连接。当用户手持电子设备进行拍摄时，电路板4控制第二驱动线圈152工作，第二驱动线圈152通电产生电磁场，第二驱动线圈152和磁性件17之间产生磁力，该磁力驱动第二驱动线圈152移动，第二驱动线圈152通过支承座151带动镜头13移动。
用户拍摄图像时输入拍摄指令，例如，用户通过操作电子设备的显示界面输入聚焦指令，电子设备中的电路板4接收该聚焦指令，并控制第二驱动线圈152中的电流方向和大小，调节第二驱动线圈152和磁性件17之间产生的磁场方向和磁力大小，从而控制第二驱动组件15的移动方向和移动量，第二驱动组件15带动镜头13移动。例如，第二驱动组件15带动镜头13沿其光轴方向移动，以对拍摄对象进行聚焦。
另外，为了使第二驱动线圈152和磁性件17的各部位之间产生均衡的磁力，第二驱动线圈152表面与磁性件17相对的区域可以与磁性件17的表面平行。参见图8，以第一固定部121内缘沿其周向均匀间隔设置有四个磁性件17为例，第二驱动线,可以大致为矩形线圈，第二驱动线圈152的各边与磁性件17对应。或者，第一固定部121的内缘沿其周向均匀间隔设置有六个或八个磁性件17，第二驱动线圈152相应为大致的六边形线圈或八边形线圈。
其中，支承座151可以为套设在镜头13外壁的圆环结构件，第二驱动线圈152内壁的部分区域与支承座151固定连接；或者，参照图9所示，支承座151的外轮廓可以为与第二驱动线圈152匹配的形状，例如，支承座151的外轮廓大致为矩形、六边形或八边形。
参照图4所示，本实施例提供的摄像模组1中，图像传感器组件16包括图像传感器161 和柔性电连接件162。图像传感器161位于镜头13的出光侧，例如，镜头13的光轴穿过图像传感器161的中心。从镜头13出射的光线照射至图像传感器161，图像传感器161将该出射光线信号经光电转换，转换为电信号，实现摄像模组1的成像功能。
柔性电连接件162用于将图像传感器161电连接至外部电路，进而，通过外部电路控制图像传感工作。具体的，柔性电连接件162的一端连接在图像传感器161上，柔性电连接件162的另一端和外部电路连接，例如，柔性电连接件162的另一端与电子设备中的电路板4连接。当用户拍摄时，电路板4上的处理器控制图像传感器161工作。
图像传感器161在工作过程中会产生热量，热量在图像传感器161上汇集，会影响图像传感器161的性能，严重时会导致图像传感器161无法正常工作，因此，需要对图像传感器161进行散热。相关技术中，图像传感器161通过其与壳体11底部之间的气隙散热，散热效率低，图像传感器161无法以高功耗模式长时间工作。例如，用户启动电子设备上的相机5分钟后，图像传感器161进入热保护模式，停止工作。
图15为本申请实施例提供的图像传感器接触底板的爆炸图。参照图6和图15所示，本实施例中，图像传感器161的散热面(图像传感器161朝向壳体11内底壁的一侧表面)与壳体11的内底壁(底板112)之间具有空隙，该空隙内填充有导热液18，通过导热液18对图像传感器161进行散热。
图像传感器161的散热面的热量，通过热传导作用传递至导热液18，导热液18将热量传导至底板112，通过底板112向外界散发热量，以此对图像传感器161进行散热。通过导热液18的热传导作用，可以提高图像传感器161的散热效率，提升图像传感器161的散热效果，进而保证图像传感器161的工作性能。
参照图15所示，壳体11的底板112上贴设有环状密封板19，导热液18位于环状密封板19围设的区域内。导热液18为可流动的液体，通过在壳体11底板112上设置环状密封板19，将导热液18限制在环状密封板19围成的区域内。其中，环状密封板19围成的区域可以对应图像传感器161的散热面，这样，导热液18所在的区域与图像传感器161的散热面对应，保证导热液18对图像传感器161的热传导效果。
为了使导热液18与图像传感器161的散热面接触充分，环状密封板19与图像传感器161的散热面之间可以具有间隙，导热液18的液面可以高于环状密封板19的表面。需要说明的是，由于环状密封板19与图像传感器161之间的缝隙很小，通过导热液18在该缝隙内的表面张力作用，可避免导热液18溢出至环状密封板19外。
另外，导热液18吸收图像传感器161的热量后，温度升高，其体积会有一定的膨胀，导致导热液18向外溢出，而环状密封板19与图像传感器161之间的缝隙可容纳导热液18的膨胀量，加上该缝隙的毛细作用，可将导热液18限制在环状密封板19所在的区域内，以免导热液18溢出环状密封板19外，对摄像模组1的其他器件造成影响。
参照图15所示，在一种实施方式中，环状密封板19上可以间隔设置有多个密封孔191。通过设置多个密封孔191，导热液18沿环状密封板19的表面向外溢出时，导热液18进入各密封孔191内，通过密封孔191对导热液18密封储存，可避免导热液18溢出至环状密封板19外。
在其他实施方式中，作为密封孔191的替代，环状密封板19的表面可以为凹凸不平的波纹面。导热液18沿环状密封板19的表面向外溢出时，波纹面的相邻两个凸起之间的凹陷 区域用于储存导热液18，波纹面的凸起区域的顶部与图像传感器161之间形成缝隙，通过导热液18在该缝隙内的表面张力作用，可防止导热液18向外扩散，因此，波纹面可防止导热液18溢出至环状密封板19外。
在环状密封板19表面加工波纹面来密封和储存导热液18时，为了防止导热液18沿波纹面的凹陷区域流动至环状密封板19的端部，可以在环状密封板1919的外缘设置止挡沿，止挡沿的高度大于波纹面凹陷区域的厚度，例如，止挡沿与波纹面的凸起区域的顶部平齐。
另外，波纹面的波纹的延伸方向(凸起区域和凹陷区域的延长方向)可以与环状密封板19的各侧边的延伸方向一致。以环状密封板19为矩形框结构为例，环状密封板19其中一侧的波纹面的波纹延伸方向与该侧边的延长方向一致，这样，导热液18向外溢出时需要越过波纹面上的凸起到达相邻的凹陷区域，波纹面可有效阻止导热液18向外溢出。
图16为本申请实施例提供的一种环状密封板的结构示意图。参照图16所示，在另一种实施方式中，作为密封孔191的替代，还可以在环状密封板19的表面上间隔设置多个条形槽192，该条形槽192沿环状密封板19的轮廓线方向延伸。以环状密封板19的轮廓为矩形框为例，条形槽192可以沿环状密封板19的边长方向延伸；其中，位于环状密封板19的角部的条形槽192可以向两边延长，例如，位于环状密封板19的角部的条形槽192为垂直弯曲的条形槽192。
如此设置，导热液18外溢时，条形槽192可以储存导热液18；并且，由于条形槽192的延伸方向大致与导热液18的溢出方向垂直，因而，条形槽192会阻碍导热液18向外溢出。
可以理解的是，通过在环状密封板19的表面上间隔设置条形槽192，相邻条形槽192之间不连通，对环状密封板19的强度影响较小，可防止环状密封板19弯折甚至断裂。另外，以图16中所示，沿a线弯折环状密封板19为例，由于弯折处两端的条形槽192的延伸方向与中部的条形槽192的延伸方向垂直，因而，会增强环状密封板19的强度。
另外，参照图16所示，由环状密封板19的内缘至外缘可以间隔设置有多排条形槽192，并且，不同排的条形槽192之间前后错开设置。这样，由环状密封板19的内缘至外缘的方向上，相邻条形槽192之间形成的间隔也前后错开，当靠近内缘的条形槽192内的导热液18外溢时，导热液18从该条形槽192端部溢出至靠近外缘的条形槽192内被储存，可防止导热液18外溢。
示例性的，环状密封板19可以为橡胶板或硅胶板。以环状密封板19上间隔设置多个密封孔191为例，环状密封板19为多孔橡胶板或多孔硅胶板。
图17为本申请实施例提供的图像传感器组件的结构示意图。参照图17所示，连接在图像传感器161上的柔性电连接件162可以包括连接部1621、活动悬臂1622和安装部1623，连接部1621与图像传感器161连接，安装部1623与外部电路(例如电子设备的电路板4)连接，活动悬臂1622位于连接部1621和安装部1623之间。
连接部1621连接在图像传感器161的一侧表面，活动悬臂1622围绕图像传感器161延伸，且活动悬臂1622位于摄像模组1的壳体11内部，安装部1623的一端与活动悬臂1622连接，安装部1623伸出至壳体11外，且安装部1623朝向电路板4延伸，安装部1623的另一端与电路板4连接。例如，安装部1623的端部和电路板4之间通过电连接器连接。
其中，活动悬臂1622为柔性电连接件162中可活动的部分，图像传感器161随第一驱动组件14移动时，活动悬臂1622随之产生相应的变形和移动，以免柔性电连接件162对图像 传感器161的移动造成限制。
本实施例中，活动悬臂1622可以环绕图像传感器161至少半圈。例如，连接部1621连接在图像传感器161一侧的侧边，活动悬臂1622从与连接部1621连接的侧边环绕图像传感器161延伸至相邻的侧边，这样，活动悬臂1622至少包括沿不同方向延伸的两部分，活动悬臂1622可使图像传感器161在其所在平面内向任意方位移动。
参照图17所示，在一种具体实施方式中，活动悬臂1622可以环绕图像传感器161一圈，以柔性电连接件162作为整体来说，柔性电连接件162由其与图像传感器161连接的一端环绕图像传感器161一圈后，伸出至壳体11外。这样，活动悬臂1622可以为图像传感器161提供足够的自由度，使图像传感器161的移动不受限制。应说明，活动悬臂1622为弹性悬臂，活动悬臂1622变形后可以恢复初始形状，以为图像传感器161的移动提供可靠的保障。
另外，柔性电连接件162的连接部1621可以与图像传感器161的表面保持水平，而活动悬臂1622与图像传感器161的表面垂直，这样易于活动悬臂1622的变形和移动，安装部1623由于伸出至壳体11外并与电路板4连接，因而，安装部1623可以贴合在电子设备后盖的内壁上，安装部1623也与图像传感器161的表面保持水平。
结合图6所示，在一些实施例中，图像传感器组件16还可以包括透光板163，该透光板163可以为透明保护板，透光板163用于保护图像传感器161不受损伤。或者，透光板163可以为滤光板，透光板163用于滤除特定波长的光线；示例性的，透光板163用于滤除不可见光线，例如滤除红外线或紫外线。
本实施例提供的摄像模组1，通过在壳体11内设置固定支架12，固定支架12包括第一固定部121和第二固定部122，第一固定部121套设在镜头13外，第二固定部122的一端连接在第一固定部121朝向壳体11底部的一侧，第二固定部122的另一端支撑在壳体11底部；通过在第一固定部121朝向壳体11底部的一侧连接第一驱动组件14，第一驱动组件14的固定件141固定在第一固定部121上，第一驱动组件14的驱动件142通过形状记忆合金线143与固定件141连接，通过形状记忆合金线143驱动驱动件142移动，驱动件142带动图像传感器组件16移动；通过在第一固定部121的内缘固定磁性件17，磁性件17驱动套设在镜头13外壁的第二驱动组件15移动，第二驱动组件15带动镜头13移动。这样，第一驱动组件14和磁性件17均连接在固定支架12上，简化了摄像模组1的结构，降低了摄像模组1的组装难度。另外，第一驱动组件14和第二驱动组件15可同步制造完成并进行性能测试，可精准测试摄像模组1的防抖性能，提高了摄像模组1的可靠性。
本实施例还提供一种摄像模组的组装方法，该组装方法用于组装如前所述的摄像模组1。具体的，该组装方法包括如下步骤：
提供镜头13，并在镜头13的外壁上套设第二驱动组件15。
提供固定支架12，该固定支架12包括第一固定部121和第二固定部122，第二固定部122连接在第一固定部121的底面，并在第一固定部121的内缘固定至少一个磁性件17。
提供第一驱动组件14；其中，第一驱动组件14包括固定件141、驱动件142和连接在固定件141和驱动件142之间的形状记忆合金线143，形状记忆合金线143包括至少两根，各形状记忆合金线143位于第一驱动组件14的不同侧。
可以理解的是，可以分别先后将第二驱动组件15套设在镜头13上、将磁性件17固定在固定支架12上，本实施例对提供第一驱动组件14的工序、镜头13和第二驱动组件15的组装 工序、固定支架12和磁性件17的组装工序，三者之间的先后顺序不作限定。其中，第一驱动组件14和第二驱动组件15可以同步制造完成。
之后，将固定支架12套设在镜头13外，使镜头13外壁上的第二驱动组件15朝向第一固定部121内缘的磁性件17。
然后，将第一驱动组件14连接在固定支架12上，使固定件141固定在第一固定部121的底面。
将第一驱动组件14组装在固定支架12上后，将图像传感器组件16固定在第一驱动组件14的驱动件142上。
最后，在固定支架12的外部套设壳体11。其中，壳体11可以包括外框111和底板112，图像传感器组件16支撑在底板112上。可以先将底板112安装在图像传感器组件16的底部，之后，将外框111与底板112固定连接。
需要说明的是，完成第一驱动组件14和第二驱动组件15与固定支架12的组装后，可以对第一驱动组件14和第二驱动组件15的性能进行测试，这样，可以提高对第一驱动组件14和第二驱动组件15整体的驱动性能测设的精确性，能够精准测试摄像模组1的防抖性能，提高摄像模组1的可靠性。第一驱动组件14和第二驱动组件15的驱动性能测试完成后，将图像传感器组件16组装在第一驱动组件14上，图像传感器组件16可以单独加工制造，可以降低图像传感器组件16的生产成本。
