具体地，当固定部272固定不动时，可动部271可相对于固定部272在垂直于光轴的平面上可移动。具体地，可动部271可用于移动微小的距离。由于固定部272与第一镜头结构210固定连接而保持固定不动，可动部271可带动感光组件240沿着垂直于光轴的方向微小地移动，从而实现摄像模组200的防抖功能。
对焦组件260和防抖组件270都与感光组件240的线路板电连接。相比于传统的利用导线将驱动马达与外部电路电连接的方式，将内置的对焦组件260和防抖组件270与感光组件240的线路板电连接，可以使摄像模组进一步的小型化，而且便于实现对两个组件同时电连接。
示例性地，为了配合对焦组件260和防抖组件270，使摄像模组200进一步地小型化，可以基于镜头切边(Lens Dcut)技术对第二镜头结构中的透镜进行切边，以去除位于感光组件240的感光路径之外的镜头部分。
本申请实施方式提供了一种采用在光学系统内部实现对焦功能并在光学系统的像侧实现防抖功能的摄像模组200。该摄像模组200不必再设置采用常规驱动马达结构时需要预留的可移动空间，而是利用了位于第一镜头结构210和感光组件240之间的第二镜头结构220。第二镜头结构220在其物侧和像侧的一定空间内移动来实现摄像模组200对焦，这样有利于降低摄像模组200的整体高度，并且有利于摄像模组200的轻薄化。而且通过对线路的布置，实现了对焦组件260和防抖组件270的配合使用，继而使摄像模组200具有更好的防抖功能。还通过使感光组件240整体在垂直于光轴的平面上移动，可确保感光组件240的线路板241和感光元件242同步移动，从而有效地保护两者之间的线路连接，保证工作状态下的电流供给。
图3是根据本申请实施方式的感光组件240的剖面结构示意图。如图3所示，感光组件240可包括线路板241、感光元件242、电子元器件243、模塑座244以及滤色片245。
线路板241可作为感光组件240的基板，用于承载感光组件240的其他部分。线路板241可具有第一表面2411和与第一表面2411相 对的第二表面2412。
感光元件242可设置于线路板241的第一表面2411。具体地，感光元件242可贴装于线路板241的第一表面2411的中心区域。感光元件242和线路板241可通过连接线246与围绕线路板241的中心区域的边缘区域电连接。
示例性地，感光元件242可为感光耦合元件(CCD)或互补性氧化金属半导体元件(COMS)。并且感光元件242可包括位于中心的感光区域和围绕感光区域的非感光区域。感光元件242的感光区域可接收经由包括第一镜头结构210和第二镜头结构220的光学系统的光线，并且具有与感光区域相对应的感光路径。
示例性地，连接线246可为金线。在感光元件240贴装于线路板241后，通过打金线工艺使金线的一端连接感光元件242，另一端连接线路板241。本领域技术人员应理解的是，连接线246还可为其他类型，例如银线、铜线等。
在一个实施方式中，所述线路板241具有容纳感光元件242的安装槽，并且该安装槽的形状与感光元件242的形状相对应。示例性地，安装槽的深度可等于线路板241的厚度。当感光元件242的厚度小于或等于线路板241的厚度时，感光元件242可完全地嵌入线路板241的安装槽中，并且还可在线路板241的第二表面2412设置补强板，例如钢板，用于增强线路板241的强度。
作为一种选择，安装槽的深度可小于线路板241的厚度，当感光元件242嵌入至该安装槽时，感光元件242可凸出于线路板241的第一表面2411(如图3所示)。同样地，还可在线路板241的第二表面2412设置补强板，例如钢板，用于增强线路板241的强度。
通过在线路板241上设置与感光元件242配合的安装槽可整体上减小感光组件240的体积和重量，有利于对感光组件240的防抖控制精确度，并且将在下文中对防抖组件270的具体结构以及工作原理进行详细地描述。
电子元器件243可设置于线路板241的第一表面2411，并与感光元件242间隔设置。具体地，电子元器件243可贴装于线路板241的 第一表面2411的边缘区域，并且与感光元件242间隔一定的距离。电子元器件243可例如被实施为电容、电阻、驱动器件等。
模塑座244可设置于线路板241的第一表面2411，并且具有阶梯式通光孔，阶梯式通光孔与感光元件242的感光路径相对应。阶梯式通光孔可具有直径不同的至少两个腔体，并且最远离感光元件242的腔体可为第一腔体。
在一个实施方式中，模塑座244可具有平行于线路板241的第一表面2411的顶面，并且阶梯式通光孔靠近感光元件242的腔体可具有倾斜的内侧面。示例性地，模塑座244可设置于线路板241的第一表面2411边缘区域，并且与感光元件242不重叠。作为一种选择，模塑座244可设置于线路板241的第一表面2411的边缘区域，并与感光元件242的非感光区域重叠(如图3所示)。
模塑座244用于将线路板241的金线模塑在其内部，在保护金线的同时可以取代传统的滤色片支架。设置模塑座244不仅可以减轻摄像模组的重量，还可以降低摄像模组的高度。
在一个实施方式中，模塑座244包覆电子元器件243和连接线246通过模塑工艺与线路板241形成整体。换言之，电子元器件243可被模塑座244封装于其内部。示例性地，模塑座244与线路板241所形成的整体还可包括感光元件242的非感光区域。将电子元器件243封装于模塑座244和线路板241之间，可有效地保护电子元器件243。
滤色片245可设置于阶梯式通光孔的第一腔体内，并且滤色片245在光轴上的厚度小于或者等于阶梯式通光孔的第一腔体在光轴上的高度，滤色片245与感光元件242之间形成间隔空间。当滤色片245的厚度小于或者等于阶梯式通光孔的第一腔体在光轴上的高度时，可使滤色片245与模塑座244的顶面处于一个平面，或者相对于模塑座244的顶面凹陷。这样有助于降低感光组件240的整体高度，从而降低摄像模组的整体高度。此外，采用模塑座244支撑滤色片245，可取消独立设置的滤色片安装座，这样可整体上减小感光组件240的体积和重量，有利于对感光组件240的防抖控制精确度，并且将在下文中对防抖组件270的具体结构以及工作原理进行详细地描述。
示例性地，滤色片245可被实施为红外截止滤色片、全透光谱滤色片以及其他滤色片或者多个滤色片的组合。
在示例性实施方式中，通过激光镭射电路实现对焦组件260与线路板241的电连接，并实现防抖组件270与线路板241的电连接。
激光镭射电路是利用镭射激光方式形成的电路。具体地，根据激光束与材料相互作用的机理，本申请的镭射激光电路可以是利用光化学反应形成的，包括光化学沉积、立体光刻、激光雕刻刻蚀等方法。例如用镭射激光束照射到对焦组件260的基体，基于在基体设置的化学剂，借助高能光子活化、引发或控制光化学反应而形成电路。激光镭射电路的形态、构型可以贴合于基体并比较自由的设计和制造出，能较好地适用于需要移动的变焦组件260和防抖组件270。
感光组件240的线路板241可利用软板等结构与外部连接，进而可利用一个连接器对变焦组件260和防抖组件270同一供电。在保证防抖性能的同时进一步减小了摄像模组200的体积，并节省了设置本申请提供给的摄像模组200的设备(例如手机)等内部的安装空间。
参考图2和图4，在示例性实施方式中，用于形成光学系统的多个镜头结构中还包括：第三镜头结构230，其沿光轴设置于第二镜头结构220的像侧，与第一镜头结构210固定连接。
在示例性实施方式中，第一镜头结构210包括第一透镜211。当第一镜头结构210包括多个透镜时，第一透镜211是其中位于最物侧的透镜，也即最远离感光组件240的透镜。
第一镜头结构210中的透镜可由塑料或者光学玻璃制成。示例性地，第一镜头结构210可包括第一镜筒，通过例如粘接将第一镜头结构210中的透镜与第一镜筒连接，用于承载并保护第一镜头结构210中的透镜。
在一个实施方式中，第一镜头结构210的至少一个透镜中，最远离感光组件240的第一透镜211的物侧面可为平面，这样可使第一透镜211与外部元件例如玻璃盖板在接触安装时完全贴合，有利于降低摄像模组200的整体安装高度。
示例性地，第一镜头结构210可包括一个平凹透镜，并且平凹透 镜的物侧面可为平面，像侧面可为凹面。应理解的是，第一透镜结构210还可为其他形式的单个透镜或多个透镜的组合。只要满足最远离感光组件240的第一透镜211的物侧面为平面且满足光学成像的要求，即可为外部元件提供一个平坦的安装平面。
同样地，第二镜头结构220可包括至少一个透镜，例如两个透镜，第二镜头结构220中的透镜可由光学塑胶或者光学玻璃制成。示例性地，第二镜头结构220可包括第二镜筒，通过例如粘接将第二镜头结构220中的透镜与第二镜筒连接，用于承载并保护第二镜头结构220中的透镜。
第三镜头结构230可包括至少一个透镜，例如三个透镜，第三镜头结构230中的透镜可由塑料或者光学玻璃制成。示例性地，第三镜头结构230可包括第三镜筒，通过例如粘接将第三镜头结构230中的透镜与第三镜筒连接，用于承载并保护第三镜头结构230中的透镜。
第一镜头结构210、第二镜头结构220以及第三镜头结构230的透镜可共同构成摄像模组200的光学成像系统。示例性地，可通过例如粘接的方式使第一镜头结构210、第二镜头结构220以及第三镜头结构230形成光轴位于同一直线的整体，用于接收外部的图像信息，并将图像信息传送至感光组件240。
参考图4，示例性地，摄像模组200还包括：安装外壳250，用于容纳第一镜头结构210和第二镜头结构220。示例性地，安装外壳250可只容纳第一镜头结构210中偏向像侧的部分结构。对焦组件260通过安装外壳250与第一镜头结构210固定连接；防抖组件270通过安装外壳250与第一镜头结构210固定连接。
进一步地，安装外壳250可容纳第一镜头结构210、第二镜头结构220和第三镜头结构230，并且安装外壳250可与第一镜头结构210、第三镜头结构230通过例如粘接的方式固定连接(未示出)。当安装外壳250安装于移动终端例如手机时，在工作状态时，与安装外壳250固定连接的第一镜头结构210和第三镜头结构230可保持静止状态。
第一镜头结构210中的至少一个透镜、第二镜头结构220中的至少一个透镜和第三镜头结构230中的至少一个透镜可共同组成摄像模 组200的光学系统。物侧入射的光线依次经由第一镜头结构210、第二镜头结构220和第三镜头结构230，进而被感光组件240接收并进行光电转化。
参考图2和图4，对焦组件260可根据摄像模组200的具体构造设计成不同的样式，可包括驱动部261和固定框架262。驱动部261可通过例如粘接、螺纹以及卡扣等方式与第二镜头结构220固定连接，具体地，驱动部261可与第二镜头结构220的第二镜筒固定连接。
固定框架262可与安装外壳250固定连接。通常而言，当安装外壳250安装于移动终端例如手机时，与安装外壳250固定连接的固定框架262可保持静止状态。此外，固定框架262可限定驱动部261沿着光轴的方向移动。
具体地，当固定框架262固定不动时，驱动部261可相对于固定框架262沿着第二镜头结构220的光轴移动微小的距离。由于第一镜头结构210的光轴、第二镜头结构220的光轴以及第三镜头结构230的光轴同轴，并且由于第一镜头结构210(和第三镜头结构230)与固定框架262固定连接从而保持固定不动，驱动部261可带动第二镜头结构220相对于第一镜头结构210沿着光轴微小地移动，实现第二镜头结构220的位置的微调，从而使第一镜头结构210在保持固定不动的状态下，使摄像模组200在其内部实现对焦功能，从而有效地提高生成的图像质量。
应理解的是，当对焦组件260的固定框架262与第三镜头结构230固定连接时，由于固定框架262对驱动部261的限定移动的作用，与驱动部261固定连接的第二镜头结构220也可与第三镜头结构230产生沿着光轴的相对位移，从而实现摄像模组200的对焦功能。
参考图4和图5，示例性地，对焦组件260包括位于第三镜头结构230的径向外侧并沿光轴的方向延伸至防抖组件270的延伸部2613，对焦组件与线路板241电连接于延伸部2613。
具体地参考图5，驱动部261可为具有中部贯通结构的长方体，中部贯通结构可容纳第二镜头结构220，并且与第二镜头结构220固定连接。可选地，在其延伸部2613设置有第一磁性结构2611。在延 伸部2613的侧面上，位于第一磁性结构2611的两侧对称地设置两个第一滚珠槽2612，并且第一滚珠槽2612与第一磁性结构2611间隔设置。此外，第一滚珠槽2612的延伸方向平行于第二镜头结构220的光轴方向。换言之，第一滚珠槽2612的延伸方向平行于光轴方向。
固定框架262可用于容纳驱动部261，在与驱动部261的延伸部2613相对应的位置设置有第一线圈结构2621和第二滚珠槽2622。
多个第一滚珠263可设置于第一滚珠槽2612和第二滚珠槽2622之间形成的空间，并且第一滚珠263的尺寸可与第一滚珠槽2612和第二滚珠槽2622的尺寸相匹配。具体地，第一滚珠槽2612与第二滚珠槽2622形成有至少一对大致平行的平面，第一滚珠263的直径与至少一对平面的间距相当。受第一滚珠263的支撑作用，当驱动部261受力时，第一滚珠槽2612相对第二滚珠槽2622沿光轴方向平行错动。进一步地，第一滚珠263的直径与一对平面的间距相当，对焦组件260还包括保持架，保持架用于使多个第一滚珠263保持相对位置。
当第一线圈结构2621施加电流时，根据电磁感应原理，由于第一线圈结构2621和第一磁性结构2611之间的磁力作用，从而使第一磁性结构2611与第一线圈结构2621产生相对作用力。具体地，当第一线圈结构2621施加的电流所感应的电磁力作用于第一磁性结构2611时，由于设置有第一线圈结构2621的固定框架262为固定不动的。因而，设置有第一磁性结构2611的驱动部261，沿着第一滚珠槽2612和第二滚珠槽2622以及与之相配合的多个第一滚珠263，产生沿着光轴方向的移动。从而可使与驱动部261固定连接的第二镜头结构220产生沿着光轴方向的移动，又由于第一镜头结构210和第三镜头结构230为固定不动的，因而可使第二镜头结构220相对于第一镜头结构210和第三镜头结构230的产生沿着光轴方向上的相对位置的变化，通过调整各个镜头结构之间的相对位置可实现摄像模组200的对焦。
通过线圈与磁性结构相配合以及滚珠与滚珠槽相配合，可实现在摄像模组200的内部对焦功能，其原理简单、易于实现、利于节约成本。此外，滚珠与滚珠槽相配合还可减小摩擦，并且有利于提升对焦时的灵敏度。
本领域技术人员应理解的是，驱动部和固定框架的具体结构形式以及实现方式不限于此，还可采用其他的形式使驱动部和固定框架在限定的方向上产生相对移动。本申请可使多个镜头结构构成的光学系统实现内部对焦功能，有利于降低摄像模组的整体安装高度，有利于摄像模组的轻薄化。
图7是根据本申请实施方式的防抖组件270的结构示意图。图8是根据本申请实施方式的可动部271的装配平面图。如图7和图8所示，在一个实施方式中，可动部271可为具有中部贯通结构的长方体，中部贯通结构可对应于感光组件240的感光路径，并且与感光组件240固定连接，例如，可动部271的底面可与感光组件240的模塑座244的顶面固定连接。在可动部271的相邻的两个侧面上可设置有第二磁性结构2711，在可动部271的顶面的四个顶角区域可设置第三滚珠槽2712。当可动部271垂直于光轴布置时，第三滚珠槽2712所在的平面可垂直于光轴。
固定部272可用于容纳可动部271，并且在固定部272与第二磁性结构2711和第三滚珠槽2712相对应的位置，分别设置第二线圈结构2721和第四滚珠槽2722。
多个第二滚珠273可设置于第三滚珠槽2712和第四滚珠槽2722之间形成的空间，并且第二滚珠273的尺寸可与第三滚珠槽2712和第四滚珠槽2722相匹配。
当第二线圈结构2721施加电流时，根据电磁感应原理，由于第二线圈结构2721和第二磁性结构2711之间的磁力作用，使第二磁性结构2711相对于第二线圈结构2721产生相对移动。具体地，当平行于x轴方向上的第二线圈结构2721施加的电流所感应的电磁力与第二磁性结构2711相吸或相斥时，由于设置有第二线圈结构2721的固定部272为固定不动的，因而设置有第二磁性结构2711的可动部271可带动感光组件240沿着y轴方向移动。当平行于y方向上的第二线圈结构2721施加的电流所感应的电磁力与第二磁性结构2711相吸或相斥时，由于设置有第二线圈结构2721的固定部272为固定不动的，因而设置有第二磁性结构2722的可动部272可带动感光组件240沿着x 轴方向移动。这样就可使可动部272带动感光组件240在xy平面上相对移动，当光轴处于z轴方向时，防抖组件270可使感光组件240在垂直于光轴的方向上移动。
本领域技术人员应理解的是，可动部和固定部的具体结构形式以及实现方式不限于此，还可采用其他形式使可动部和固定部产生相对移动。例如，防抖组件和变焦组件可选用压电陶瓷。本申请通过利用防抖组件调整感光组件的相对位置而实现摄像模组防抖的效果，可以避免通过调整多组镜头而使成像质量下降，有利于提高摄像模组的成像质量。
图9是本申请实施方式的摄像模组200的装配示意图。如图9所示，在一个实施方式中，安装外壳250可容纳感光组件240。可动部271与感光组件240的顶面固定连接，固定部272的外周与安装外壳250的上部边缘的内侧固定连接。这样不仅可以有效地保护感光组件240，同时还可以保证摄像模组200的底部的平整度。当安装外壳250直接安装在移动终端时，可以保证安装以后摄像模组200整体结构的平整度。
参考图10，本申请还提供一种摄像模组的制造方法1000，包括：
S101，在第一镜头结构的像侧设置第二镜头结构。其中，还可以沿着第一镜头结构的光轴在第二镜头结构的像侧设置包括第三镜头结构在内的后续镜头结构。

S103，在第二镜头结构的像侧设置包括线路板的感光组件。第二镜头结构位于感光路径上。其中，沿着光轴的各镜头结构都位于感光路径上，这些镜头结构中第一镜头结构距离感光组件最远。步骤S103与步骤S101的顺序不限定，可根据组装需求而选择。
S104，在感光组件处设置防抖组件，其中，防抖组件用于驱动感光组件在垂直于光轴的平面上移动。
示例性地，防抖组件包括固定部和可动部。步骤S103和S104可同时完成。示例性地，在步骤S103和S103之前，包括：将固定部与第一镜头结构固定连接(例如通过固定框架或外壳固定连接)；将可动部与感光组件固定连接，进而在将第一镜头结构(以及与第一镜头结构连接的其他组件)设置于感光组件的感光路径上时，同时实现了设置防抖组件的步骤。
S105，电连接防抖组件与线路板并且电连接对焦组件与线路板。具体地，可包括在防抖组件或对焦组件上形成镭射激光电路；以及通过镭射激光电路电连接防抖组件或对焦组件与线路板。
图11是根据本申请实施方式的摄像模组的装配示意图，如图11所示，在一个实施方式中，可将第三镜头结构230、第二镜头结构220、第一镜头结构210依次设置于感光组件(未示出)的感光路径上。具体地，可先将感光组件设置在安装外壳250’内并且使其位置相对固定，然后将第三镜头结构230、第二镜头结构220以及第一镜头结构210依次设置于该感光组件的感光路径上，以使三者的光轴处于同一直线。采用这种组装方法，可保证整体结构的稳定性，并且镜头组件容纳在安装外壳250’内部，可保证各个镜头结构之间的紧凑性，从而降低组装的摄像模组的组装高度。
在另一实施方式中，也可利用分体式组装的方法，即将第一镜头结构、第二镜头结构以及第三镜头结构的位置相对固定，并使三者的透镜共同用于成像。示例性地，可在第二镜头结构与对焦组件进行组装后，调整第一镜头结构、与对焦组件组装的第二镜头结构以及第三镜头结构的光轴，以用于构成可成像的光学镜头组件。之后，再将其与摄像模组的其他结构进行组装。具体地，可利用机器视觉和主动对准技术使第一至第三镜头结构的光轴处于同一直线。
示例性地，还可以包括如下步骤：将第一镜头结构、第三镜头结构与安装外壳固定连接，并且将驱动部与第二镜头结构固定连接。
通过方法1000制造的摄像模组，通过调整光学系统内的各个镜头 结构之间的相对距离，实现对焦功能。这种方式可有效地降低摄像模组的整体高度，有利于摄像模组的轻薄化。
图12是本申请实施方式的移动终端20的结构示意图。图13是图12的移动终端20的左视图。如图12和图13所示，移动终端20包括机体外壳202和如上文中任一实施方式所描述的至少一个摄像模组200，例如两个。摄像模组200可设置于机体外壳202内部，并且机体外壳202可具有与摄像模组200的感光路径相匹配的安装孔。
在一个实施方式中，当第一镜头结构包括所述第一透镜时，第一透镜的物侧面可与机体外壳202的外表面处于同一平面。这样安装有摄像模组200的移动终端20，可避免摄像模组200的高度过高而造成的凸出于移动终端20的机体外壳202的问题，这样有利于提高用户的操作体验。
在一个实施方式中，摄像模组200还可以应用于移动终端20的具有显示面板的一侧，不仅可以使摄像模组不凸出于机体外壳，还可以保证前置摄像模组的成像质量。
