具体实施方式
下面将结合本申请实施例中的图1至图10，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅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，本领域技术人员在没有作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。
本申请实施例提供一种摄像模组10，摄像模组10可以用于实现电子设备的拍照、录像、人脸识别解锁、扫码支付等功能。此外，需要说明的是，摄像模组10可以是前置式摄像头，也可以是后置式摄像头，本实施例对此不作限定。以下结合附图具体说明摄像模组10的结构。
其中，请参考图1和图2，图1为本申请实施例提供的摄像模组10的一种结构示意图，图2为图1所示的摄像模组10的一种爆炸结构示意图。摄像模组10 至少包括防抖组件100、图像传感器组件200、镜头300和壳体400。
壳体400可以包括上盖410和下盖420，上盖410和下盖420可以形成容置空间，至少部分图像传感器组件200和防抖组件100可以设置于容置空间内，部分镜头300可以设置于容置空间内、另一部分镜头300可以伸出容置空间外。可以理解的是，如图1和图2所示，下盖420的面积可以大于上盖410的面积，以使得下盖420可以作为摄像模组10的底板，以便于摄像模组10连接于电子设备。当然，实际生产中，该下盖420的面积也可以等于或小于上盖410的面积，本申请实施例对此不进行限定。
镜头300的材质可以是玻璃或塑胶等。镜头300内部可设有多层镜片，镜头300可以采集外部光线并可以改变光线的传播路径，并可对光线进行聚焦。如图2所示，摄像模组10还可以包括滤光片组件500，该滤光片组件500可以在镜头300的光轴方向设置于镜头300和图像传感器组件200之间，该滤光片组件500可以包括一层或多层滤光片510及承载滤光片510的滤光片支架520，多层滤光片510会相互矫正过滤光线，以在光线通过镜头300时，多层滤光片510层层过滤杂光(例如红外光)，以便于增加摄像模组10的成像效果。
图像传感器组件200可以在镜头300的光轴方向上与镜头300相对设置，图像传感器组件200可以包括图像传感器210和图像传感器电路板220，镜头300、图像传感器210和图像传感器电路板220可以沿第一方向H1上下层叠设置，该第一方向H1可以是摄像模组10的厚度方向，镜头300与图像传感器210可以相互平行。图像传感器210可以但不限于是电荷耦合元件(Charge Coupled Device，简称CCD)、互补金属氧化物半导体(Complementary Metal Oxide Semiconductor，简称CMOS)等类型的影像传感器。图像传感器210主要用于接收来自镜头300采集的光线，并将光信号转化为电信号，以便于实现摄像模组10的成像需求。图像传感器电路板220可以承载图像传感器210并与图像传感器210电性连接，以为图像传感器210提供电能及控制信号。
防抖组件100可以在镜头300的光轴方向设置于图像传感器210远离镜头300的一侧，防抖组件100可与图像传感器210连接以驱动图像传感器210运动。防抖组件100可以用于改善摄像模组10因用户在使用过程中发生抖动而产生的成像效果，以使得图像传感器210的成像效果能够满足用户的使用需求。防抖组件100可以提供驱动力，以驱动图像传感器210运动。
基于光学防抖技术，电子设备(或摄像模组10)的陀螺仪或加速度计等传感器可以检测到镜头300的抖动以生成抖动信号，并将该抖动信号传递至电子设备和/或摄像模组10的处理芯片，电子设备和/或摄像模组10的处理芯片可以 计算出防抖组件100需要补偿的位移量，以使得防抖组件100可以根据镜头300的抖动方向及其位移量对镜头300进行补偿，从而改善或摄像模组10因用户在使用过程中发生抖动而产生的成像效果。
其中，请结合图2并请参考图3和图4，图3为图2所示的防抖组件100与图像传感器组件200的一种连接示意图，图4为图3所示的防抖组件100与图像传感器组件200的一种爆炸结构示意图。防抖组件100可以包括承载板110和驱动机构120。
承载板110可以作为图像传感器210的线路板并承载图像传感器210。承载板110可以包括间隔设置的活动件111和固定件112，承载板110的固定件112可以与摄像模组10、电子设备或其他结构上的部件连接并固定不动，活动件111可以承载摄像模组10或电子设备的图像传感器210(或图像传感器组件200)，图像传感器210可以设置并直接或间接连接于活动件111上。固定件112可以套设在活动件111的外周缘，固定件112与活动件111之间可以形成间隙以使得活动件111可以相对固定件112运动。摄像模组10或电子设备的图像传感器210(或图像传感器组件200)可以设置并连接于该活动件111上并随活动件111的运动而同步运动。
可以理解的是，活动件111上可以设有第一电连接端1111(例如但不限于焊盘，需要说明的是，图4中对第一电连接端1111的标识仅限于指示第一电连接端1111的一种形式，活动件111上的任一焊盘均可以是此处的第一电连接端1111)，该第一电连接端1111可以与图像传感器210的电性连接。固定件112上可以设有第二电连接端1121(例如但不限于焊盘，需要说明的是，图4中对第二电连接端1121的标识也仅限于指示第二电连接端1121的一种形式，固定件112上的任一焊盘均可以是此处的第二电连接端1121)，该第二电连接端1121可以与防抖组件100、摄像模组10或电子设备的模组电路板700电性连接。当第一电连接端1111和第二电连接端1121通过电连接件(例如但不限于弹性件113)电性连接时，图像传感器210可以通过第一电连接端1111、电连接件和第二电连接端1121与模组电路板700电性连接，该模组电路板700可以将图像传感器210的电信号引出至防抖组件100而与摄像模组10或电子设备的电路板、电源等部件电性连接。
可以理解的是，由于固定件112可以与防抖组件100、摄像模组10或电子设备连接而固定不动，从而，与固定件112的第二电连接端1121电连接的模组电路板700也不需要随移动件121或活动件111运动，模组电路板700不需要进行弯折后焊接，本申请实施例的模组电路板700的焊接工艺简单，尺寸较小。
承载板110可以在镜头300的光轴方向上与驱动机构120相对设置。驱动机构120可以设置于承载板110的一侧。例如，如图3和图4所示，驱动机构120可以设置在承载板110远离图像传感器210的一侧，以使得驱动机构120可以在承载板110的下方驱动承载板110运动。当然，驱动机构120也可以设置在承载板110的上方一侧，例如设置在承载板110和图像传感器组件200的上方一侧，以使得驱动机构120可以在承载板110和图像传感器组件200的上方驱动承载板110运动。本申请实施例对驱动机构120的设置位置不进行具体的限定。
驱动机构120包括移动件121和多个形变件122，移动件121可与活动件111直接或间接连接，从而，移动件121、活动件111及设置于活动件111上的图像传感器210(或图像传感器组件200)可以形成一整体。每一形变件122的一端可与固定件112直接或间接连接、另一端可与移动件121直接或间接连接，多个形变件122在通电状态下可发生形变以带动移动件121、活动件111和图像传感器210形成的整体运动，以使得移动件121、活动件111和图像传感器210可以同步运动。例如多个形变件122在通电状态下可发生形变以带动移动件121、活动件111、图像传感器210沿垂直于镜头300的光轴方向移动或围绕镜头300的光轴方向转动，图像传感器210可以在防抖组件100的作用下实现X轴、Y轴或XOY平面内转动。
可以理解的是，镜头300的光轴方向可以是第一方向H1，该第一方向H1可以是竖直方向，例如是坐标轴中的Z轴方向。垂直于镜头300的光轴方向可以是第二方向，该第二方向可以是水平面内的任一水平方向，例如是坐标轴中的X轴方向或Y轴方向。围绕镜头300的光轴方向，可以是垂直于镜头300的光轴的平面内的任一方向，例如是坐标轴中的XOY平面内的任一方向。
可以理解的是，多个形变件122的材料为形状记忆合金(shape memory alloys，SMA)制作形成，形状记忆合金在通电状态下可以使得形状记忆合金被加热并使其变形，变形时可以使得多个形变件122的长度发生变化。当对多个形变件122进行通电、或者对多个形变件122传输不同大小的电流时，多个形变件122的长度可以发生变化，由于每一形变件122的一端随承载板110的固定件112固定不动、另一端随移动件121运动，从而，长度发生变化的多个形变件122可以带动移动件121运动，移动件121也可带动与之直接或间接连接的活动件111和图像传感器210运动。
本申请实施例的防抖组件100，驱动机构120包括移动件121和多个形变件122，移动件121与承载板110的活动件111连接，每一形变件122的一端与移动件121连接、另一端与承载板110的固定件112连接，从而多个形变件122发生形 变时可以带动移动件121运动、移动件121可以带动活动件111及设置于活动件111上的图像传感器210运动，从而，本申请实施例的防抖组件100可以实现图像传感器210的防抖功能。同时，形变件122的两端分别与固定件112和移动件121连接，形变件122不需要占据活动件111的空间，形变件122不会影响活动件111上电路的分布，可以降低形变件122对活动件111上电路的影响。并且，移动件121与承载板110相互独立，在生产装配工艺中，移动件121和承载板110可以分别进行模块化生产，以提高移动件121和承载板110的适应性。需要说明的是，移动件121与承载板110也可以采用同一套生产工艺一起生产。本申请实施例对移动件121与承载板110的具体制备过程不进行限定。
其中，请再次参考图3和图4，驱动机构120还可以包括多个可动端123和多个固定端124。
多个可动端123可以设置于移动件121，多个固定端124可以设置于固定件112。一个形变件122的一端可以直接或间接连接于一个可动端123、另一端可以直接或间接连接于一个固定端124。形变件122在通电状态下长度发生改变时，与形变件122连接的可动端123可随形变件122的长度的变化而随移动件121一起移动，与形变件122连接的固定端124则随固定件112一起固定而不移动。
可以理解的是，一个或多个可动端123可以间隔地设置并连接于移动件121上，多个可动端123中的两个或多个还可以不间隔设置而相邻(或相互连接)设置。同理，一个或多个固定端124可以间隔地设置并连接于固定件112上(例如间隔设置于固定件112的背面)，多个固定端124中的两个或多个也可以不间隔设置而相邻(或相互连接)设置。本申请实施例对多个可动端123、多个固定端124的设置方式不进行具体的设置。
可以理解的是，如图4所示，驱动机构120可以包括间隔设置的两个可动端123和间隔设置的两个固定端124，例如，包括第一可动端1231、第二可动端1232、第一固定端1241和第二固定端1242。其中，第一可动端1231、第二可动端1232、第一固定端1241和第二固定端1242可以形成四边形结构，第一可动端1231、第二可动端1232可以位于四边形结构的一条对角线L1上，第一固定端1241和第二固定端1242可以位于四边形结构的另一条对角线L2上，第一可动端1231、第二可动端1232、第一固定端1241和第二固定端1242可以形成四边形结构的四个顶点。此时，防抖组件100还可以对应设置四个形变件122，四个形变件122可以对应四边形结构的四条边设置。基于四边形结构容易变形的特性，当形变件122发生形变时，形变件122更容易受到位于顶点处的可动端123及固定端124的影响而使得四边形结构发生改变从而更容易带动活动件111及设置于活动件111 上的图像传感器210运动。
可以理解的是，一个或多个可动端123可以一体成型于移动件121上，一个或多个固定端124也可以一体成型于固定件112上。当形变件122通过缠绕、卡嵌、焊接等方式连接于可动端123或固定端124，相较于形变件122直接连接于固定件112的方案而言，本申请实施例形变件122与可动端123、固定端124连接的过程中，不容易对固定件112造成损坏，不易损坏固定件112上的电路走线。
可以理解的是，可动端123、固定端124的数量可等于形变件122的数量的一半，以使得一个可动端123可以连接两条形变件122的端部，一个固定端124也可以连接两条形变件122的端部，从而，本申请实施例的驱动机构120可以设置较少的可动端123和固定端124。
可以理解的是，防抖组件100、摄像模组10或电子设备还可以包括驱动控制芯片，该驱动控制芯片可以设置于承载板110的固定件112上并形成使得形变件122产生形变的驱动电路。或者，请参考图5，图5为图3所示的防抖组件与图像传感器组件的另一种爆炸结构示意图。固定件112上还可以单独设置驱动电路101，驱动控制芯片可以通过前述的模组电路板700而与固定件112上的驱动电路101实现电连接。该多个可动端123、多个固定端124中的至少一个可以是导电器件，以使得驱动电路101可以通过多个可动端123，或者通过多个固定端124，或者同时通过多个可动端123和多个固定端124与形变件122电性连接，从而，驱动控制芯片可为形变件122提供驱动电流。
可以理解的是，该可动端123、固定端124可以具有一定的高度，以使得可动端123、固定端124可将承载板110与移动件121、形变件122隔离开。从而，多个形变件122发生形变时不易与承载板110接触，可以避免承载板110对形变件122的形变干扰；同时，也可以防止承载板110上的电路与形变件122接触而短路。
当然，防抖组件100也可以单独设置一个或多个支撑件，每一支撑件可以位于移动件121与承载板110之间，以使得每一支撑件可以将移动件121和承载板110间隔开。
本申请实施例的防抖组件100设置多个可动端123和固定端124，形变件122通过该可动端123与固定端124实现与承载板110的固定件112及驱动机构120的移动件121连接，形变件122的连接工艺更简单，不会影响固定件112上的电路走线；同时，可动端123和固定端124可作为导电器件实现形变件122的供电，可以简化形变件122的供电电路布置，实现防抖组件100的小型化设计。
其中，请结合参考图3和图4并请参考图6和图7，图6为图4所示的驱动机构 120与承载板110的第一种结构示意图，图7为图4所示的驱动机构120与承载板110的第二种结构示意图。多个形变件122可以环绕移动件121设置，以使得形变件122可以更好地控制移动件121的移动。
示例性的，驱动机构120的移动件121可以大致为矩形框结构。移动件121可以包括首尾相连的第一部1211、第二部1212、第三部1213和第四部1214，第一部1211和第三部1213相对设置且可沿X轴设置，第二部1212和第四部1214相对设置可沿Y轴设置。第一部1211和第四部1214之间可以形成第一端部1215，第二部1212和第三部1213之间可以形成第二端部1216，第一端部1215和第二端部1216可以位于移动件121的一条对角线L3上。
固定件112可为矩形框结构，活动件111可位于矩形框内部。固定件112可以包括首尾相连的第五部1122、第六部1123、第七部1124和第八部1125，第五部1122和第七部1124相对设置，第六部1123和第八部1125相对设置。第五部1122可相对于第一部1211设置，第六部1123可相对于第二部1212设置，第七部1124可相对于第三部1213设置，第八部1125可相对于第四部1214设置。第五部1122和第六部1123之间可以形成第三端部1126，第七部1124和第八部1125之间可以形成第四端部1127，该第三端部1126和第四端部1127可以位于移动件121的另一条对角线L4的延长线上。
当驱动机构120包括两个可动端123和两个固定端124例如第一可动端1231、第二可动端1232、第一固定端1241和第二固定端1242时，该第一可动端1231可以设置于第一端部1215，第二可动端1232可以设置于第二端部1216，第一固定端1241端可以设置于第三端部1126，第二固定端1242可以设置于第四端部1127。从而，第一可动端1231和第二可动端1232可以位于移动件121的对角线L3上，第一固定端1241和第二固定端1242端可以位于移动件121的对角线L4的延长线上。可以理解的是，移动件121的对角线L3可以与前述四边形结构的对角线L1共线，移动件121的对角线L4可以与前述四边形结构的对角线L2共线。
多个形变件122可以包括第一形变件1221、第二形变件1222、第三形变件1223和第四形变件1224。第一形变件1221可以相对于第一部1211和第五部1122设置，第二形变件1222可以相对于第二部1212和第六部1123设置，第三形变件1223可以相对于第三部1213和第七部1124设置，第四形变件1224可以相对于第四部1214和第八部1125设置。第一形变件1221的一端可与第一可动端1231连接、另一端可与第一固定端1241连接；第二形变件1222的一端可与第一固定端1241连接、另一端可与第二可动端1232连接；第三形变件1223的一端可与第二可动端1232连接、另一端部可与第二固定端1242连接；第四形变件1224的一端可与 第二固定端1242连接、另一端可与第一可动端1231连接。

一个或多个弹性件113可以设置于活动件111和固定件112之间，例如设置于活动件111的外周缘及固定件112的内周缘之间。每一弹性件113的第一端a1可以与固定件112连接并固定不动、第二端a2可以与活动件111连接并随活动件111运动。一个或多个弹性件113可以为活动件111提供与其运动方向相反的弹性作用力以牵扯活动件111的运动，弹性件113提供的弹性作用力及驱动机构120提供的驱动力可以共同作用于活动件111，以使得活动件111可以稳定地停留在某一位置，从而使得活动件111及图像传感器210的防抖控制更精准。
可以理解的是，弹性件113可以采用具有弹性恢复力的材质制备，弹性件113可以但不限于包括各种弹簧。每一弹性件113可以包括一个或多个子弹性件，例如图8中，每一弹性件113可以由多根弹性丝螺旋形成，此时，弹性件113的第一端a1可以是多根弹性丝共同形成的一端部，第二端a2可以是多根弹性丝共同形成的另一端部。当然，实际生产中，每一弹性件113也可以仅由一根弹簧形成。本申请实施例对弹性件113的具体结构不进行限定，凡是可承受活动件 111在驱动机构120带动下运动产生的作用力并可具有弹性恢复力的弹性件113的结构，均在本申请实施例的保护范围内。

可以理解的是，如图8所示，每一弹性件113可以包括顺次连接的第一弹性部b1、第一拐角部b2和第二弹性部b3，该第一弹性部b1可以连接于固定件112，第二弹性部b3可以连接于活动件111，第一弹性部b1和第一拐角部b2的第一连线与第一拐角部b2和第二弹性部b3的第二连线可呈预设夹角，该预设夹角可以但不限于为九十度。本申请实施例的弹性件113包括上述三个部分，弹性件113可以形成幅度较大的扭簧结构，弹性件113对活动件111的牵扯力更大，弹性件113可以进一步保证活动件111的稳定性。

在相邻的两个弹性件113中，其中一个弹性件113(例如在前的弹性件113)的第二端a2可与另一个弹性件113(例如再后的弹性件113)的第一端a1在活动件111上的投影可以相邻且可位于活动件111的同一侧边上。可以理解的是，此处的相邻可以是指前一个弹性件113的第一端a1与后一个弹性件113的第二端a2之间的距离可处于一较小的预设范围内，以使得相邻的两个弹性件113的弹性扭力可以覆盖活动件111的整条侧边，活动件111的稳定性更好。
其中，当固定件112为矩形框结构、活动件111为矩形板结构时，固定件112可以包括前述的第五部1122、第六部1123、第七部1124和第八部1125，活动件111可以包括第一侧边1112、第二侧边1113、第三侧边1114和第四侧边1115。相应的，承载板110可以包括四个弹性件113，例如第一弹性件1131、第二弹性件1132、第三弹性件1133和第四弹性件1134。第一弹性件1131的第一端a1可连接于第五部1122、第二端a2可连接于第二侧边1113，第二弹性件1132的第一端a1可连接于第六部1123、第二端a2可连接于第三侧边1114，第三弹性件1133的 第一端a1可连接于第七部1124、第二端a2可连接于第四侧边1115，第四弹性件1134的第一端a1可连接于第八部1125、第二端a2可连接于第一侧边1112。从而，每一弹性件113分别连接固定件112的一侧边及与该侧边对应的活动件111的相邻侧边，每一弹性件113可形成扭簧结构，一方面，扭簧结构可为活动件111的运动提供牵引力而提高活动件111的稳定性；另一方面，扭簧结构也可以避免活动件111的运动幅度过大而使得弹性件113与活动件111分离。
需要说明的是，以上仅为本申请实施例的弹性件113与活动件111、固定件112的一种示例性连接方式。弹性件113的具体连接方式并不局限于上述说明，例如弹性件113还可以直接连接固定件112的一边框及其对应的活动件111的侧边。本申请实施例对弹性件113的具体连接方式不进行限定。
