光学镜头是摄像模组的必要部件之一，其能够汇聚入射光线而使摄像模组成像。近年来，随着用户对于摄像模组的成像品质的要求越来越高，摄像模组的像素也在不断的提升，与此同时，对光学镜头的设计要求也越来越高。现有的摄像模组被配置一体式光学镜头，其包括一个镜筒和被设置于该镜筒的多个镜片，由于一体式光学镜头的设计和组装方法的技术限制，导致配置一体式光学镜头的摄像模组难以满足对于大光圈的要求。为了解决一体式光学镜头存在的上述问题，业界提出了一种分体式光学镜头，其将光学镜头的一系列镜片分为至少两个镜片群，每个镜片群分别包括一个镜筒和被安装于该镜筒的至少一个镜片，每个镜片群在分别被组装和校准后再组装为一个完整的光学镜头。这种分体式光学镜头虽然具有一体式光学镜头所不具备的优势，但是这种分体式光学镜头仍然需要被安装于一个驱动器(例如，音圈马达)，以通过驱动器驱动分体式光学镜头沿着摄像模组的光轴方向运动而实现对焦，这导致摄像模组在对应于光学镜头的位置的长宽尺寸无法被缩小，以至于导致摄像模组难以被应用于电子设备的前侧。换言之，即便是将业界新出现的分体式光学镜头配置于摄像模组，摄像模组不适于作为电子设备的前置摄像模组。

依本发明的另一个方面，本发明进一步提供所述光学镜头200的组装方法，其中所述组装方法包括如下步骤：
(a)允许多个所述镜头群201大致同光轴地设置；
(b)校准这些所述镜头群201的Z方向的间隙；
(c)按照各所述镜头群201在所述光学镜头200整体中的敏感度从低到高的方式依次校准这些所述镜头群201的XY方向的位置；以及
(d)组装校准后的这些所述镜头群201，以组装所述光学镜头200。
优选地，这些所述镜头群201分别为所述上镜头群10、所述对焦镜头群20以及所述下镜头群30，所述上镜头群10和所述下镜头群30的相对位置由所述外壳40相对固定，所述对焦镜头群20由所述驱动机构50与延伸于所述驱动机构50和所述外壳40之间的所述弹片202悬浮地保持于所述上镜头群10和所述下镜头群30之间。

具体地，参考附图9至图10B、图12A至图13F，所述承载部52的所述延伸臂523具有一下侧水平延伸部分5231、一上侧水平延伸部分5232以及一倾斜延伸部分5233，其中所述下侧水平延伸部分5231自所述受驱件521一体地向内延伸，所述上侧水平延伸部分5232自所述承载环522一体地向外延伸，所述倾斜延伸部分5233的相对两端分别延伸至和被连接于所述下侧水平延伸部分5231和所述上侧水平延伸部分5232，如此所述承载部52的所述受驱件521的高度位置低于所述承载环522的高度位置而使所述驱动部53的所述线圈532下沉，以有利于降低所述摄像模组的高度尺寸。

附图14示出了本发明的所述摄像模组的一个变形示例，与附图8至图13F示出的所述摄像模组不同的是，在附图14示出的所述摄像模组的这个具体示例中，所述下镜头群30被直接固定地设置于所述基座70，如此由所述基座70和所述外壳40相互配合保证所述下镜头群30和所述上镜头群10的相对位置关系。例如，所述下镜头群30的所述第三镜筒31的周缘可以通过胶水被粘接于所述基座70，以允许所述下镜头群30被直接固定地设置于所述基座70。
附图13A至图13F示出了本发明的所述光学镜头200的组装过程，其包括如下阶段：
预固定一标准镜头群300于所述承载部52的所述承载环522；
以所述标准镜头群300对应于所述外壳40的所述避让空间48的方式可活动地设置所述承载部52于所述外壳40的所述壳体空间41，此时，所述标准镜头群300的底面高于所述外壳40的所述壳面体44的表面，以允许所述标准镜头群300在后续被横向移除；
固定地设置所述下镜头群30于所述外壳40的所述壳体空间41和预固定所述上镜头群10于所述外壳40，并且所述下镜头群30、所述标准镜头群300和所述上镜头群10大致同光轴；
校准所述下镜头群30、所述标准镜头群300和所述上镜头群10；
经所述外壳40的所述避让空间48移除所述标准镜头群300和移入所述对焦镜头群20，以得到所述光学镜头。
在所述光学镜头200的组装过程中，通过引入所述标准镜头群300的方式能够提高所述光学镜头200的整体阈值，从而在高阈值表现下对所述光学镜头200进行调整。
优选地，在所述光学镜头200的组装过程中，在所述对焦镜头群20替代所述标准镜头群300后，再次校准所述上镜头群10、所述对焦镜头群20和所述下镜头群30，如此有利于保证所述光学镜头200的光学性能和所述摄像模组的成像品质。
优选地，在所述光学镜头200的组装过程中，移除所述标准镜头群300的方式是沿着垂直于所述光学镜头200的光轴方向经所述外壳40的所述避让空间48移除所述标准镜头群300，相应地，移入所述对焦镜头群20的方式是沿着垂直于所述光学镜头200的光轴方向经所述外壳40的所述避让空间48移入所述对焦镜头群20。
依本发明的另一个方面，本发明进一步提供所述光学镜头200的组装方法，其中所述组装方法包括如下步骤：
(a)固定地设置所述下镜头群30于所述外壳40的所述壳体空间41；
(b)以所述上镜头群10凸出于所述外壳40的方式，贴装所述上镜头群10于所述外壳40；以及
(c)以所述上镜头群10、所述对焦镜头群20和所述下镜头群30同光轴的方式，被可驱动地设置所述对焦镜头群20于所述外壳40的所述壳体空间41，以得到所述光学镜头。
优选地，在所述步骤(b)之前，所述组装方法进一步包括步骤：
(d)预固定所述上镜头群10于所述外壳40；
(e)以所述上镜头群10、所述标准镜头群300和所述下镜头群30同光轴的方式，保持所述标准镜头群300于所述上镜头群10和所述下镜头群30之间；
(f)以所述下镜头群30为基准，校准所述标准镜头群300；以及
(g)以所述下镜头群30和所述标准镜头群300为基准，校准所述上镜头群10。
在本发明的所述组装方法中，通过引入所述标准镜头群300的方式能够提高所述光学镜头200的整体阈值，从而在高阈值表现下对所述光学镜头200进行调整。
值得一提的是，所述光学镜头200的所述上镜头群10、所述对焦镜头群20和所述下镜头群30的关系是：(1)Z方向的间隙主要影响所述光学镜头200的场曲；(2)XY方向的位置主要影响所述光学镜头200的峰值；(3)所述上镜头群10、所述对焦镜头群20和所述下镜头群30之间的倾斜主要影响所述光学镜头200的倾斜和像散等。由于在所述组装方法中用所述标准镜头群300替代所述对焦镜头群20，因此所述上镜头群10、所述标准镜头群300和所述下镜头群30的关系同样满足上述内容。
因此，在对所述光学镜头200进行光学设计时，需要均衡考虑所述光学镜头200的整体光学性能的敏感度，即不会导致某一具体镜片或某一具体镜头群受到所述上镜头群10、所述对焦镜头群20和所述下镜头群30的关系的影响而过于敏感，以至于导致所述光学镜头200的整体光学性能因为该镜片或者该镜头群1敏感度较高而造成整体光学性能下降的问题。但是由于镜片的作用不同和光焦度不同，势必会存在敏感度从低到高的镜头群，通常情况下，按照从像侧到物侧的顺序，镜头群的敏感度依次升高，即，所述对焦镜头群20的敏感度高于所述下镜头群30的敏感度，所述上镜头群10的敏感度高于所述对焦镜头群20的敏感度(或者，所述标准镜头群300的敏感度高于所述下镜头群30的敏感度，所述上镜头群10的敏感度高于所述标准镜头群300的敏感度)。因此，在本发明的所述组装方法中，在校准所述上镜头群10、所述标准镜头群300和所述下镜头群30的Z方向的间隙后，需要按照所述上镜头群10、所述标准镜头群300和所述下镜头群30在所述光学镜头200的整体中的按照敏感度从低到高的方式依次校准所述上镜头群10、所述对焦镜头群20和所述下镜头群30的XY方向的位置，如此保证所述光学镜头200的整体光学性能。
进一步地，在上述方法中，在移除所述标准镜头群300后，首先，经所述外壳40的所述避让空间48，允许所述对焦镜头群20沿着垂直于所述光学镜头200的光轴方向移入所述外壳40的所述壳体空间41，其次，以所述下镜头群30和所述上镜头群10为基准，校准所述对焦镜头群20，以设置所述对焦镜头群20于所述外壳40的所述壳体空间41。
优选地，在所述步骤(e)中，由所述承载部52承载所述标准镜头群300于所述上镜头群10和所述下镜头群30之间，并且在移除所述标准镜头群300后，所述对焦镜头群20被移至所述承载部52而由所述承载部52承载所述对焦镜头群20于所述外壳40的所述壳体空间41。更优选地，所述上镜头群10和所述外壳40之间的间隙小于所述对焦镜头群20和所述承载部52之间的间隙，如此在以所述下镜头群30和所述上镜头群10为基准校准所述对焦镜头群20时，所述对焦镜头群20能够被提供更大的补偿范围，以便于弥补误差而保证应用有所述光学镜头200的所述摄像模组的成像品质。
依本发明的另一个方面，本发明进一步提供一光学镜头的组装方法，其中所述组装方法包括如下步骤：
(A)预固定所述标准镜头群300于所述承载部52的所述承载环522；
(B)以所述标准镜头群300对应于所述外壳40的所述避让空间48的方式可活动地设置所述承载部52于所述外壳40的所述壳体空间41；
(C)固定地设置所述下镜头群30于所述外壳40的所述壳体空间41和预固定所述上镜头群10于所述外壳40，并且所述下镜头群30、所述标准镜头群300和所述上镜头群10大致同光轴；
(D)校准所述下镜头群30、所述标准镜头群300和所述上镜头群10；以及
(E)经所述外壳40的所述避让空间48移除所述标准镜头群300和移入所述对焦镜头群20，以得到所述光学镜头。
优选地，所述组装方法进一步包括步骤：(F)允许所述封盖60封闭所述外壳40的所述避让空间48，以阻止灰尘等污染物经所述光学镜头200的所述外壳40的所述避让空间48进入所述光学镜头200的内部，如此保证所述光学镜头200的可靠性。
参考本发明的说明书附图之附图15至图18B，依本发明的另一较佳实施例的一摄像模组在接下来的描述中将被揭露和被阐述，其中所述摄像模组包括一感光组件100和被设置于所述感光组件100的一内对焦光学镜头200。
具体地，参考附图15至图17B，所述感光组件100包括一电路板101、一感光芯片102、一镜座103以及一滤光片104，其中所述感光芯片102被贴装于所述电路板101，其中所述镜座103以所述镜座103至少环绕在所述感光芯片102的感光区域的四周的方式被设置于所述电路板101，其中所述滤光片104以所述滤光片104被保持在所述感光芯片102的感光路径的方式被贴装于所述镜座103的顶侧，其中所述内对焦光学镜头200被直接地设置于所述镜座103。入射光线在依次穿过所述内对焦光学镜头200和所述感光组件100的所述滤光片104后能够被所述感光芯片102接收，以在后续，所述感光芯片102能够进行光电转化而成像。
优选地，所述镜座103一体地成型于所述电路板101，如此：一方面，在所述镜座103和所述电路板101之间不需要设置胶水层而能够降低所述摄像模组的高度尺寸，另一方面， 所述镜座103能够补强所述电路板101的强度，以保证所述电路板101的平整度。优选地，所述镜座103可以进一步包埋所述感光芯片102的非感光区域的一部分，如此所述镜座103一体地结合于所述电路板101和所述感光芯片102。
另外，所述感光组件100进一步包括至少一电子元器件105，其中所述电子元器件105被贴装于所述电路板101，所述镜座103可以包埋所述电子元器件105。
继续参考附图15至图18B，所述内对焦光学镜头200包括一外壳10、一物侧镜头群20、一对焦镜头群30以及一像侧镜头群40，其中所述外壳10具有一壳体空间11以及分别连通于所述壳体空间11的一顶部开口12和一底部开口13，其中所述物侧镜头群20以所述物侧镜头群20对应于所述外壳10的所述顶部开口12的方式被贴装和凸出于所述外壳10，其中所述对焦镜头群30以所述对焦镜头群30对应于所述外壳10的所述顶部开口12的方式被可驱动地设置于所述外壳10的所述壳体空间11，其中所述像侧镜头群30被固定地设置于所述外壳10的所述壳体空间11，并且所述物侧镜头群20、所述对焦镜头群30和所述像侧镜头群40被沿着所述内对焦光学镜头200的光轴方向依次布置，如此由所述外壳10集成所述物侧镜头群20、所述对焦镜头群30和所述像侧镜头群40为一个整体。通过这样的方式，入射光线在依次穿过所述内对焦光学镜头200的所述物侧镜头群20、所述对焦镜头群30和所述像侧镜头群40以及所述感光组件100的所述滤光片104后能够被所述感光芯片102接收。
需要说明的是，所述对焦镜头群30被设置能够沿着所述内对焦光学镜头200的光轴运动而通过改变所述对焦镜头群30相对于所述物侧镜头群20和所述像侧镜头群40的位置的方式实现所述摄像模组的对焦，如此在所述摄像模组对焦过程中，所述物侧镜头群20和所述像侧镜头群40相对于所述感光组件100的位置不变，从而不会影响所述内对焦光学镜头200的光学总长。
换言之，在所述摄像模组对焦过程中，所述内对焦光学镜头200的外露部件的位置和尺寸没有改变，即，所述内对焦光学镜头200的所述外壳10和所述物侧镜头群20的位置和尺寸没有改变，而是通过改变所述对焦镜头群30的相对位置实现对焦，如此使得所述内对焦光学镜头200具有内对焦功能，从而使得所述摄像模组特别适于作为便携式电子设备的前置摄像模组。
特别地，所述物侧镜头群20的尺寸较小，并且所述物侧镜头群20以凸出于所述外壳10的方式被贴装于所述外壳10，以允许所述内对焦光学镜头200采用“小头”的设计方案，如此在所述摄像模组作为便携式电子设备的前置摄像模组时，一方面，所述物侧镜头群20能够更靠近便携式电子设备的屏幕的开孔位置，以有利于所述摄像模组获得更大的视场角和通光量，从而提升所述摄像模组的成像品质，另一方面，不会增加屏幕的开孔尺寸，从而满足开孔小型化的要求。
所述物侧镜头群20包括一物侧镜筒21和被安装于所述物侧镜筒21的至少一物侧镜片22，其中所述物侧镜筒21被贴装于所述外壳10，以贴装所述物侧镜头群20于所述外壳10。所述对焦镜头群30包括一对焦镜筒31和被安装于所述对焦镜筒31的至少一对焦镜片32。所述像侧镜头群40包括一像侧镜筒41和被安装于所述像侧镜筒41的至少一像侧镜片42， 其中所述像侧镜筒41被固定地安装于所述外壳10，以固定地安装所述像侧镜头群40于所述外壳10的所述壳体空间11。
具体地，在附图15至图18B示出的所述摄像模组的这个具体示例中，所述物侧镜头群20包括一个所述物侧镜筒21和两个所述物侧镜片22，两个所述物侧镜片22被沿着所述物侧镜筒21的高度方向间隔设置，所述对焦镜头群30包括一个所述对焦镜筒31和一个所述对焦镜片32，所述像侧镜头群40包括一个所述像侧镜筒41和两个所述像侧镜片42，两个所述像侧镜片42被沿着所述像侧镜筒41的高度方向间隔设置。换言之，在附图15至图18B示出的所述摄像模组的这个具体示例中，所述内对焦光学镜头200包含5个镜片，其分别是两个所述物侧镜片22、一个所述对焦镜片32和两个所述像侧镜片42。
需要说明是的，所述物侧镜头群20的两个所述物侧镜片22的光学性质可以不同，相应地，所述像侧镜头群40的两个所述像侧镜片42的光学性质可以不同。
继续参考附图15至图18B，所述外壳10包括一壳面体14和一环绕体15，其中所述环绕体15自所述壳面体14的周缘一体地向下延伸，以在所述壳面体14和所述环绕体15之间形成所述壳体空间11，其中所述壳面体14形成有所述顶部开口12，所述环绕体15界定所述底部开口13，其中所述物侧镜头群20的所述物侧镜筒21被贴装于所述外壳10的所述壳面体14。
优选地，所述物侧镜头群20的外径大于所述对焦镜头群30的外径，如此在所述对焦镜头群30被可驱动地保持于所述外壳10的所述壳体空间11的基础上便于贴装所述物侧镜头群20的所述物侧镜筒21于所述外壳10的所述壳面体14，从而使得所述摄像模组的结构更合理。
进一步地，所述外壳10包括至少一安装臂16，其中所述安装臂16自所述壳面体14的内壁向下一体地延伸，以使所述安装臂16位于所述壳体空间11，其中所述像侧镜头群40的所述像侧镜筒41被安装于所述安装臂16，以固定地设置所述像侧镜头群40于所述外壳10的所述壳体空间11。

附图19示出了本发明的所述摄像模组的一个变形示例，与附图15至图18B示出的所述摄像模组不同的是，在附图19示出的所述摄像模组的这个具体示例中，所述外壳10和所述驱动单元50的所述固定部51是一体式结构。换言之，所述驱动单元50驱动单元50的所述驱动部54的所述磁铁541可以被直接固定地设置于所述外壳10，如此能够进一步减小所述摄像模组的长宽尺寸而能够减小所述摄像模组的整体体积。所述弹片53的外侧被直接地固定于所述外壳10。
附图20示出了本发明的所述摄像模组的另一个变形示例，与附图15至图18B示出的所述摄像模组不同的是，在附图20示出的所述摄像模组的这个具体示例中，所述像侧镜头群40被直接固定地设置于所述基座70，如此由所述基座70和所述外壳10相互配合保证所述物侧镜头群20和所述像侧镜头群30的相对位置关系。
依本发明的另一个方面，本发明进一步提供所述内对焦光学镜头200的组装方法，其中所述组装方法包括如下步骤：
(a)允许所述物侧镜头群20、所述对焦镜头群30和所述像侧镜头群30大致同光轴地设置；
(b)校准所述物侧镜头群20、所述对焦镜头群30和所述像侧镜头群40的Z方向的间隙；
(c)按照所述物侧镜头群20、所述对焦镜头群30和所述像侧镜头群40在所述内对焦光学镜头200整体中的敏感度从低到高依次校准所述像侧镜头群40、所述对焦镜头群30和所述物侧镜头群20的XY方向的位置；以及
(d)组装校准后的所述像侧镜头群40、所述对焦镜头群30和所述物侧镜头群20，以得到所述内对焦光学镜头200。
优选地，所述物侧镜头群20和所述像侧镜头群40的相对位置由所述外壳10相对固定，所述对焦镜头群30由所述驱动单元50驱动单元50悬浮地保持在所述外壳10的所述壳体空间11。
优选地，在上述方法中，首先，以所述像侧镜头群40为基准，校准所述对焦镜头群30的Z方向的间隙，其次，以所述像侧镜头群40和所述对焦镜头群30为基准，校正所述像侧镜头群40的Z方向的间隙，再次，以所述像侧镜头群40为基准，校正所述对焦镜头群30的ZY方向的位置，最后，以所述像侧镜头群40和所述对焦镜头群30为基准，校正所述物侧镜头群20的XY方向的位置。
值得一提的是，所述内对焦光学镜头200的所述物侧镜头群20、所述对焦镜头群30和所述像侧镜头群40的关系是：(1)Z方向的间隙主要影响所述内对焦光学镜头200的场曲；(2)XY方向的位置主要影响所述内对焦光学镜头200的峰值；(3)所述物侧镜头群20、所述对焦镜头群30和所述像侧镜头群40的倾斜主要影响所述内对焦光学镜头200的倾斜和像散。
因此，在对所述内对焦光学镜头200进行光学设计时，需要均衡考虑所述内对焦光学镜头200的整体光学性能的敏感度，即不会导致某一具体镜片或镜头群受所述物侧镜头群20、所述对焦镜头群30和所述像侧镜头群40的关系的影响而过于敏感，以至于导致所述内对焦光学镜头200的整体光学性能因为该镜片或该镜头群的敏感度较高而造成整体光学性能下降的问题。但是由于镜片的作用和光焦度不同，势必会存在敏感度从低到高的镜头群，通常情况下，按照从像侧到物侧的顺序，这些镜头群的敏感度依次升高，即，所述对焦镜头群30的敏感度高于所述像侧镜头群40的敏感度，所述物侧镜头群20的敏感度高于所述对焦镜头群30的敏感度。因此，在本发明的所述组装方法中，在校准所述物侧镜头群20、所述对焦镜头群30和所述像侧镜头群40的Z方向的间隙后，需要按照敏感度从低到高的方式依次校准所述物侧镜头群20、所述对焦镜头群30和所述像侧镜头群40的XY方向的位置，如此保证所述内对焦光学镜头200的整体性能。

经所述外壳10的所述避让空间18移除所述标准镜头群300和移入所述对焦镜头群30，以得到所述内对焦光学镜头200。
在所述内对焦光学镜头200的组装过程中，通过引入所述标准镜头群300的方式能够提高所述内对焦光学镜头200的整体阈值，从而在高阈值表现下对所述内对焦光学镜头200进行调整。

附图26A至图26I示出的所述光学镜头100的组装过程，其包括下述阶段。
参考附图26A，预固定一标准镜头群300于所述承载部52的所述承载环522。
参考附图26B，通过所述弹片54连接所述承载环52和所述固定部51，其中所述固定部51被安装于所述外壳40的所述主壳体41，以使所述承载部52和所述标准镜头群300被保持在所述外壳40的所述壳体空间43，其中所述标准镜头群300对应于所述主壳体41的所述装配通道413。

接着，按照所述物侧镜头群10、所述标准镜头群300和所述像侧镜头群30在所述光学镜头100的整体中的敏感度对所述物侧镜头群10、所述标准镜头群300和所述像侧镜头群30进行校准。
值得一提的是，所述物侧镜头群10、所述标准镜头群300和所述像侧镜头群30的关系是：(1)Z方向的间隙主要影响所述光学镜头100的场曲；(2)XY方向的位置主要影响所述光学镜头100的峰值；(3)所述上镜头群10、所述标准镜头群300和所述下镜头群30之间的倾斜主要影响所述光学镜头100的倾斜和像散等。因此，在对所述光学镜头100进行光学设计时，需要均衡考虑所述光学镜头100的整体光学性能的敏感度，即不会导致某一具体镜片或者某一具体镜头群受到所述物侧镜头群10、所述标准镜头群300和所述像侧镜头群30的关系的影响而过于敏感，以至于导致所述光学镜头100的整体光学性能因为该镜片或者该镜头群的敏感度过高而造成整体光学性能的下降的问题。但是由于镜片的作用不同和光焦度不同，势必会存在敏感度从低到高的镜头群，通常情况下，按照从像侧到物侧的顺序，镜头群的敏感度依次升高，即，所述标准镜头群300的敏感度高于所述像侧镜头群30的敏感度，所述物侧镜头群10的敏感度高于所述标准镜头群300的敏感度。
因此，对所述物侧镜头群10、所述标准镜头群300和所述像侧镜头群30进行校准的具体步骤是：首先，以所述像侧镜头群30为基准，校准所述标准镜头群300；其次，以所述像侧镜头群30和所述标准镜头群300为基准，校准所物侧侧镜头群10。

参考附图26G和图26H，经所述主壳体41的所述装配通道413，移入所述对焦镜头群20，并预固定所述对焦镜头群20于所述承载部52的所述承载环522。在移入所述对焦镜头群20的过程中，为了避免所述主壳体41剐蹭所述对焦镜头群20，所述对焦镜头群20被横向移入。即，经所述主壳体41的所述装配通道413，沿着垂直于所述光学镜头100的光轴方向移动所述对焦镜头群20而对所述对焦镜头群20执行移入操作。
优选地，所述对焦镜头群20有一个对焦镜片21组成，其中所述对焦镜片21的厚度尺寸小于所述主壳体41的所述装配通道413的高度尺寸，所述对焦镜片21的宽度尺寸小于所述主壳体41的所述装配通道413的宽度尺寸，以允许所述对焦镜片21经所述主壳体41的所述装配通道413被顺利地移入所述外壳40的所述壳体空间43，和被预固定于所述承载部52的所述承载环522。

所述摄像模组1000的所述光学镜头100内置对焦功能，即，所述摄像模组1000通过驱动所述对焦镜头群20的方式实现对焦，如此在所述摄像模组1000对焦的过程中，所述物侧镜头群10和所述像侧镜头群30相对于所述感光组件200的位置不变，从而不会影响所述光学镜头100的光学总长，因此，所述电子设备本体2000不需要预留供所述摄像模组1000的所述光学镜头100移动的空间，以有利于所述电子设备的轻薄化。
并且，所述摄像模组1000的所述光学镜头100的所述物侧镜头群10的尺寸较小，并且所述物侧镜头群10凸出于所述外壳40而使所述摄像模组1000采用“小头”设计方案，如此在所述摄像模组1000作为所述电子设备的前置摄像模组时，一方面，所述物侧镜头群10能够更靠近所述电子设备的屏幕的开孔位置而有利于所述摄像模组1000获得更大的视场角和通光量，以提升所述摄像模组1000的成像品质，另一方面，不会增加屏幕的开孔尺寸，满足开孔小型化的要求。
附图31至图32B示出了依本发明的另一较佳实施例的所述摄像模组1000，与附图28和图29示出的所述摄像模组1000不同的是，在附图31至图32B示出的所述摄像模组1000的这个具体示例中，所述对焦镜头群20包括一对焦镜筒22和被设置于所述对焦镜筒22的至少一个所述对焦镜片21。
进一步地，所述物侧镜头群10的所述物侧镜筒11的底侧设有一环形槽111，如此在贴装所述封盖60时，用于粘接所述封盖60的内侧和所述物侧镜头群10的胶水在溢出后能够进入所述物侧镜筒11的所述环形槽111，通过这样的方式，一方面，能够避免溢出的胶水于所述外壳40的所述壳体空间43内污染所述物侧镜头群10、所述对焦镜头群20和所述像侧镜头群30，另一方面，能够避免溢出的胶水于所述外壳40的内壁或所述封盖60的内壁形成凸起而造成杂散光。
优选地，所述对焦镜头群20的所述对焦镜筒22的一突出部221对应于所述物侧镜筒11的所述环形槽111，并且在所述对焦镜头群20被驱动时，所述对焦镜筒22的所述突出部221能够进入所述物侧镜筒11的所述环形槽111，以允许所述物侧镜头群10避让所述像侧镜头群20，通过这样的方式，所述对焦镜头群20可以具有更大的行程范围。
值得一提的是，所述物侧镜筒11的底侧通过设置两个凸环112的方式形成所述环形槽111，所述物侧镜筒11的两个所述凸环112和所述对焦镜筒22的所述突出部221相互配合具有减少杂散光的作用，以提高所述摄像模组1000的成像效果。
依本发明的一个方面，本发明提供所述光学镜头100的组装方法，其中所述组装方法包括如下步骤：
(a)设置所述物侧镜头群10于所述外壳40的所述壳体空间43；
(b)以所述物侧镜头群10凸出于所述外壳40的方式，贴装所述物侧镜头群10于所述外壳40；以及
(c)以所述像侧镜头群30和所述物侧镜头群10为基准，在校准所述对焦镜头群20后，固定所述对焦镜头群20于被可驱动地设置于所述外壳40的所述壳体空间43的所述承载部52，以得到所述光学镜头100。
为满足小型化和足够的驱动力的要求，本发明提供一种驱动镜头的部分镜片来实现对焦的光学驱动组件。该光学驱动组件包括分体式镜头组件，镜头组件包括多个镜头部，其中一镜头部被设置在于驱动装置的可动载体上，其余镜头部被固定于驱动装置，从而实现部分镜头相对于其他镜头部移动实现对焦。
一方面，光学镜头内部空间有限，马达部件的尺寸难以减小被设置在光学镜头内部，另一方面，马达结构复杂，零件数量增加，组装的累积公差链变长，使得组装难度增大，组装的精度难以保证。另外，由于被固定的镜头部之间通过胶水粘结，而镜头部的镜筒多为树脂，两者的热膨胀系数不同，导致被组装好的摄像模组的镜头在烘烤等工艺过程中的变异量不同，镜头部之间发生变异，导致最终的摄像模组成像质量下降。

在部分可选实施例中，如图35和图39所示，该第三镜头部安装位2213的连接臂22131自壳体主体2211向内且向下延伸至结合部22132，第一镜头部安装位2212的承靠部22122在高度方向上高于连接臂22131和结合部22132，使得第一镜头部11与第三镜头部13在沿光轴方向上存在高度间隙。承靠部22122高于载片212，该第三镜头部安装位2213与第三镜头部13的固定接触的结合部22132低于载片212，即结合部22132与承靠部22122形成一行程间距，载片212在该行程间距内上下移动，带动第二镜头部12在驱动力的作用下移动。
该驱动装置20的固定部22的底座222包括一底座主体2221，该底座主体2221设置有一底座通孔22211，第三镜头部13设置在该底座通孔22211中，并与该底座主体2221的内侧固定连接。底座222设置在壳体221内，该底座222固定连接至该壳体221的壳体主体2211的内侧，进一步的，底座222的周面与壳体主体2221的靠近像侧的端部固定连接。该底座222和壳体221构成固定部22。
该底座222与该壳体主体2221固定连接，该第三镜头部13被设置固定在底座222内，该第三镜头部13的第三镜筒132外侧、该壳体221以及该底座222构成第一容置空间，该载体211以及该驱动线圈231在第一容置空间被可活动地设置，在第一容置空间内可沿光轴方向发生移动。
该第一镜头部11、该壳体221以及该第三镜头部13构成第二容置空间，该载片212以及该第二镜头部12在第二容置空间内被可活动地设置，在第二容置空间内沿光轴方向发生移动。
该载体组件21构成驱动装置20的可动部，底座222、壳体221构成驱动装置20的固定部22，驱动组件23的驱动线圈231和驱动磁石232分别设置在可动部和固定部22，第一镜头部11以及第三镜头部13被固定设置于固定部22，第二镜头部12被固定于可动部，固定部22与其他部件形成第一容置空间和第二容置容置空间，可动部在第一容置空间和第二 容置空间内在驱动力的作用下发生移动，从而带动第二镜头部12发生移动，从而实现光学内部对焦。
如图36和图38所示，该驱动装置20还包括保持组件24，该保持组件24用于将可动部可活动地支撑保持于固定部，并支撑可动部能够相对于固定部22移动。在本申请实施例中，该保持组件24可以为弹性构件，适于带动载体组件21以及第二镜头部12回复至原始位置(即未被驱动时的位置)，包括上弹性构件241和下弹性构件242。上弹性构件241和下弹性构件242被相对地设置在载体211的相对两侧，即上弹性构件241被设置在载体211的入光侧，下弹性构件242被设置在载体211的出光侧，以将载体组件21以及第二镜头部12可复位地悬持于固定部22的容置空间内。
具体地，该上弹性构件241被延伸设置在驱动磁石232、载体211以及壳体221之间，整体呈薄片状结构，包括弹性内环、弹性外环以及弹性连接梁。内环设置在载体211的上表面，外环承载在驱动磁石232上，与驱动磁石232固定连接，弹性连接梁连接内环与外环，包括多次的水平弯折，能够提供弹性复位力。
同样地，该下弹性构件242被延伸设置在底座222与载体211之间，包括弹性内环、弹性外环和延伸于弹性内环和弹性外环之间的弹性连接梁，其中，弹性内环固定于载体211，弹性外环固定于底座222。在部分可选实施例中，下弹性构件242包括相对称设置的至少二弹性单元，弹性单元包括内环、外环以及延伸连接内环和外环的弹性连接梁。
当载体211在驱动力的作用下沿着光轴方向移动时，弹性构件发生形变以积蓄弹性力；当载体211被停止驱动时，弹性构件的弹性力得以释放，驱动载体211回复至原始位置，带动与载体211连接的第二镜头部12回复至原始位置。
该弹性连接梁自弹性外环弯折地延伸至弹性内环，以便为载体211的移动预留出足够的空间，不仅可以为载体211的大移动行程提供保障，也可以减小载体211的驱动阻力，改善光学对焦灵敏度。可以理解的是，弹性连接梁的长度越长，弹性连接梁的弯折越多，弹性连接梁在产生形变后其本身的变形越小，在弹性连接梁受到拉伸后更容易复位。
如图36和37所示，在一些实施例中，该载体211进一步包括第一防撞凸台2116，第一防撞凸台2116分别被设置在载体211的上端面2113和下端面2114，以使得载体211在沿着光轴方向移动时不会直接撞击到底座222和壳体221上，避免设置在载体211的第二镜头部12因为撞击而发生损坏。第一防撞凸台2116可以是弹性模量小于载体211的材料，例如，硅胶。第一防撞凸台2116可通过注塑一体成型于载体211，也可以是通过粘结的方式固定于载体211。
该载体上端面2113的第一防撞凸台2116的上表面突出于上弹性构件241，载体下表面2114的第一防撞凸台2116的下表面突出于下弹性构件242，以避免载体211移动的过程中，弹性构件与固定部的底座222或壳体221发生碰撞，导致弹性构件损坏。

该载体211通过上弹性构件241的弹性连接梁和下弹性构件242的弹性连接梁被悬持地设置于壳体221内，通过弹性连接梁的形变为载体211预留出一定的移动空间，以及，为载体211提供一定的回复力。

该驱动装置20还包括感测构件，用于感测载体211所处的位置，根据拍摄需求进行对焦以得到清晰的图像。
通过对驱动装置20的合理设计，即第一镜头部11安装在壳体221的第一镜头部安装位2212，第三镜头部13与壳体221的第三镜头部安装位2213固定，以结构坚固稳定的壳体221为安装基准面，在部分优选实施例中，该壳体为金属壳体一体成型而成，实现第一镜头部11和第三镜头部13的稳定固定，使得第一镜头部11和第三镜头部13的相对位置能够保持稳定，受温度或者其他环境因素影响更小、可靠性更优保证；同时第一镜头部11和第三 镜头部13的组装公差更小，组装一致性更好。
第二镜头部12被设置在第一镜头部11和第三镜头部13之间，第一镜头部11和第二镜头部12在沿光轴方向之间预留有第一间隙，第一镜头部11承靠在第一镜头部安装位2212的承靠部22122，第二镜头部12设置在载体组件21上，载体组件21的载体211的第一防撞凸台2116与壳体221的承靠部22122之间具有第二间隙，其中，第一间隙小于第二间隙，第二间隙限制载体211上下移动的机械行程距离，以避免载体211在驱动装置20的作用下上下移动的过程中，第二镜头部12与第一镜头部11发生碰撞，导致光学成像系统画质受损。
