请参阅图1至图2，本发明的实施例提供了一种镜头模组，包括自动对焦组件10、光学防抖组件20、弹性支撑组件30以及驱动装置40及底壳50，光学防抖组件20在镜头的光轴S方向上与自动对焦组件10间隔设置，底壳50设于自动对焦组件10远离光学防抖组件20的一侧，底壳50具有一凹腔51，自动对焦组件10部分安装于凹腔51中，弹性支撑组件30连接于自动对焦组件10和光学防抖组件20之间，驱动装置40用于驱动光学防抖组件20在垂直于光轴S的方向上移动。
请参阅图1至图6，自动对焦组件10包括第一底座11和固定于第一底座11朝向光学防抖组件20一侧的第一电路板12，光学防抖组件20包括第二底座21和固定于第二底座21远离自动对焦组件10一侧的第二电路板22，弹性支撑组件30包括至少两个弹性支撑件31，每个弹性支撑件31包括第一连接端311、第二连接端312和连接于第一连接端311与第二连接端312之间的弹性支撑本体313，第一连接端311与自动对焦组件10上的第一电路板12电性连接，第二连接端312与光学防抖组件20上的第二电路板22电性连接。弹性支撑件31不仅能起到支撑自动对焦组件10的作用，同时还具有电性连接第一电路板12和第二电路板22的作用。
请进一步参阅图7，自动对焦组件10具有两个相对设置的第一侧壁13以及连接在两第一侧壁13之间且相对设置的两第二侧壁14，第一侧壁13与第二侧壁14围成环形。驱动装置40包括设置在第一侧壁13外侧和第二侧壁14外侧的两个绑线夹42、以及设置在两绑线夹42之间的形状记忆合金线41，每个绑线夹42包括设于光学防抖组件20朝向自动对焦组件10一侧（即第二电路板22底部）的第一导电板421和自第一导电板421向自动对焦组件10方向弯折延伸的第二导电板422，两个绑线夹42的第二导电板422分别设置在相邻的第一侧壁13和第二侧壁14的外侧，第二导电板422垂直于第一导电板421设置，这样装配后可以减少镜头模组在水平方向（即垂直于光轴S方向）的尺寸。
作为优选地实施方式，定义第二导电板422具有最大面积的面为主平面424，主平面424的法向朝向第一侧壁13或朝向第二侧壁14设置，以确保这样设置后可以减少镜头模组在水平方向的尺寸。
请进一步参阅图8，绑线夹42与第二电路板22电性连接，形状记忆合金线41包括分别连接至相邻两个绑线夹42的第二导电板422的末端411和位于两个末端411之间的驱动端412，驱动端412与相邻的第一侧壁13和第二侧壁14的连接处即拐角处配合连接，自动对焦组件10的拐角处可作为受力点，可用于支撑固定形状记忆合金线41，请参阅图10，形状记忆合金线41通电后温度升高，这里取其中形状记忆合金线41中的第二形状记忆合金线414为例，形状记忆合金线41收缩产生F（+Y）、F（-X）拉力，其合力为F提供+X/-Y的45度方向的驱动力。
请进一步参阅图9，作为优选地实施方式，光学防抖组件20朝向自动对焦组件10的一侧凹设有用于容置第一导电板421的凹槽23，凹槽23具有与自动对焦组件10相对设置的底槽面24，底槽面24凸设有安装柱25，安装柱25为两个间隔设置的凸柱，第一导电板421贯穿开设有安装孔423，安装柱25卡插于安装孔423中，这样既可以缩小镜头模组沿光轴S方向的尺寸，又可以缩小镜头模组沿垂直光轴S方向的尺寸，通过安装柱25与安装孔423的配合，可增强绑线夹42固定在光学防抖组件20上的稳定性。
请进一步参阅图10-13，绑线夹42的固定端设于自动对焦组件10的正上方，可以防止额外增加镜头模组沿垂直光轴S方向的尺寸，也即缩小了镜头模组沿垂直光轴S方向的尺寸。
作为优选地实施方式，自动对焦组件10靠近光学防抖组件20一端的外侧壁且位于拐角处凸设有第一台阶15及与第一台阶15呈阶梯设置的第二台阶16，第二台阶16相对于第一台阶15靠近光学防抖组件20，且第二台阶16在垂直于光轴S方向上的厚度大于第一台阶15在垂直于光轴S方向上的厚度，驱动端412点胶固定于第一台阶15远离光学防抖组件20的一侧，通过点胶简化了形状记忆合金线41与自动对焦组件10之间的装配流程，降低了镜头模组的制作成本，第二台阶16与第一台阶15的连接处可作为上述所述的受力点，且第一台阶15之朝向驱动端412的一侧为弧形结构，以降低形状记忆合金线41与第一台阶15之间的磨损。
本实施例中驱动装置40设有四个，即绑线夹42的数量为八个、形状记忆合金线41的数量为四个，第一侧壁13外侧的中部和第二侧壁14外侧的中部均设有两个所述绑线夹42，每个驱动端412与一个第一侧壁13和第二侧壁14的连接处连接，每个形状记忆合金线41沿自动对焦组件10的周向等间距分布，对应地，每一组与同一个形状记忆合金线41相连接的两个绑线夹42沿光学防抖组件20的周向等间距分布。
当形状记忆合金线41通电后，温度升高，形状记忆合金线41收缩产生与其相对应的第一侧壁13和第二侧壁14成45℃夹角的驱动力，使自动对焦组件10沿垂直于光轴S方向移动，进而达到光学防抖功能。通过设置四根形状记忆合金线41，沿自动对焦组件10的周向等间距分布，可以使自动对焦组件10向四个方向移动。
具体地，第二底座21贯穿开设有穿孔211，弹性支撑本体313穿过穿孔211使第二连接端312焊接到第二电路板22上。可将第二连接端312焊接到第二电路板22上，这样即保证弹性支撑体与光学防抖组件20的电连接，又确保弹性支撑体与光学防抖组件20连接的稳定性，进而保证自动对焦组件10与光学防抖组件20间隔连接的稳定性。在本实施例中，第二连接端312自弹性支撑本体313朝靠近光轴S的方向延伸，防止额外增加镜头模组沿垂直光轴S方向的尺寸，也即缩小了镜头模组沿垂直光轴S方向的尺寸。
在本发明实施例中，弹性支撑件31采用的材料为SUS304H，其具有良好的耐蚀性能和焊接性能，其在刚度方面完全可以确保自动对焦组件10和光学防抖组件20两者之间的结构稳定性，而且又具有一定的弹性，防止被折断。
弹性支撑本体313设于自动对焦组件10的外侧，弹性支撑本体313包括第一延伸部314、第二延伸部315、第三延伸部316和第四延伸部317，第一延伸部314和第二延伸部315均与光轴S垂直设置，且第一延伸部314与第二延伸部315互为垂直，第三延伸部316、第四延伸部317均与光轴S平行设置，第三延伸部316的一端与第一连接端311连接、另一端与第一延伸部314连接，第四延伸部317的一端与第二连接端312连接、另一端与第二延伸部315连接，第一延伸部314远离第一连接端311的一端与第二延伸部315远离第二连接端312的一端相连接，该种连接方式结构简单，并且同时缩小镜头模组沿光轴S方向的尺寸。
本实施例中的弹性支撑件31设有四个，四个第一连接端311沿自动对焦组件10的周向等间距分布，四个第二连接端312沿光学防抖组件20的周向等间距分布，每个第一连接端311通过弹性支撑本体313在沿光轴S的逆时针或者顺时针的方向上连接到相邻的第二连接端312。
在本实施例中，每个弹性支撑本体313和每个形状记忆合金线41的位置相对应设置，当其中一根形状记忆合金线41收缩完毕，实现光学防抖功能后，相应的弹性支撑本体313根据自身的特性使自动对焦组件10移回到原来的位置，也即对自动对焦组件10产生回复力。
本实施例中底壳50的中部开设有第一透光孔52，自动对焦组件10上开设有用于容置镜头的固定孔17，光学防抖组件20上设有用于光线穿设的第二透光孔26，第一透光孔52、固定孔17及第二透光孔26都沿光轴S方向设置。
镜头模组还包括设于第二电路板22之远离第二底座21一侧的盖板60，第二电路板22包括安装于第二底座21上方的第一电板221及自第一电板221朝远离第二底座21一侧弯折延伸的第二电板222，盖板60包括与第一电板221贴合的第一防护板61及与第二电板222贴合的第二防护板62，第一防护板61与第二防护板62连接，该盖板60可保护第二电路板22，便于第二电路板22上的pin脚折弯设置，盖板60上设有与第二透光孔26相配合的第三透光孔63。
本发明中镜头模组在垂直于镜头光轴S的平面内的运动方式如下：
为了便于描述，在图15中将四根形状记忆合金线41分别用：第一形状记忆合金线413、第二形状记忆合金线414、第三形状记忆合金线415以及第四形状记忆合金线416表示；其中，α方向为-X与Y所在平面的45度方向、β方向为X与Y所在平面的45度方向、δ方向为X与-Y所在平面的45度方向、γ方向为-X与-Y所在平面的45度方向；
参照图15，当自动对焦组件10需要朝α方向运动时，只需要将第二形状记忆合金线414通电收缩，第二形状记忆合金线414便会产生一个朝α方向的力，从而驱动自动对焦组件10朝α方向运动。同理，当自动对焦组件10需要朝β方向运动时，只需要将第一形状记忆合金线413通电收缩，第一形状记忆合金线413便会产生一个朝β方向的力，从而驱动自动对焦组件10朝β方向运动。自动对焦组件10朝向γ与δ方向的运动原理与上述相同，此处不再赘述，当自动对焦组件10为正方形时，α/β/γ/δ方向与正方形的对角线方向一致。
以上的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
