Description

摄像模组 技术领域
本申请涉及摄像模组领域，尤其涉及摄像模组其在不工作状态下具有相对较小的高度尺寸，在工作状态下具有相对较大的有效焦距，以解决摄像模组在整体高度尺寸和较大有效焦距之间的技术矛盾。
背景技术
随着移动电子设备的普及，被应用于移动电子设备的用于帮助使用者获取影像(例如，视频或者图像)的摄像模组的相关技术得到了迅猛的发展和进步。目前在市场中，配置于移动电子设备(例如，智能手机)的摄像模组需要实现多倍变焦拍摄功能。
为实现多倍变焦拍摄的技术需求或长焦拍摄的技术需求，需配置至少一长焦摄像模组，这里，长焦摄像模组指的是具有较大有效焦距的摄像模组。随着变焦倍数的增加，长焦摄像模组的总有效焦距会随之增大导致摄像模组的整体高度尺寸不断增高，这显然难以迎合电子设备轻薄化的发展趋势。
为了解决传统的直立式摄像模组在高度尺寸和较大有效焦距之间的技术矛盾，大多数厂商采用潜望式摄像模组来替代传统的直立式摄像模组。相较于传统的直立式摄像模组，潜望式摄像模组通过光转折元件(例如，棱镜、反射镜等)来改变其成像光学路径，从而实现摄像模组整体高度尺寸降低的同时满足具有较大有效焦距的光学设计需求。
然而，潜望式摄像模组具有相对更为复杂的结构，这一方面导致了其成本的上升，另一方面，也直接导致其工艺难度的增加。此外，潜望式摄像模组是以牺牲长宽方向上的尺寸为代价来换得其在高度方向上的缩减，而长宽尺寸较大的潜望式摄像模组在终端设备上并不美观，影响了用户体验。
还有，在光学性能方面，虽然潜望式摄像模组具有相对较大的有效焦距，但其有效焦距为固定值，也就是，潜望式摄像模组的光学性能具有相对较差的可调整性。为了满足消费者对于摄像模组的多样化需求，通常需要为电子设备配置多个摄像模组，即，为电子设备配置多摄摄像模组，这不仅带来了成本的激增，也进一步地加剧了工艺难度。
因此，需要一种优化的摄像模组方案来解决摄像模组在高度尺寸和较大有效焦距之间的技术矛盾。
发明内容

如图1至图8所示，根据本申请实施例的摄像模组300被阐明，其中，所述摄像模组300，包括感光组件10、被保持于所述感光组件10的感光路径上的光学镜头20，以及，用于驱动所述光学镜头20和感光组件10移动以进行光学性能调整的驱动组件30。特别地，在本申请实施例中，所述光学镜头20和所述驱动组件30具有特殊的结构配置使得所述摄像模组300的工作状态和非工作状态下切换，其中，在不工作状态下所述摄像模组300具有相对较小的高度尺寸，在工作状态下所述摄像模组300具有相对较大的有效焦距，以解决传统直立式摄像模组300在整体高度尺寸和较大有效焦距之间的技术矛盾。并且，通过对所述驱动组件30的合理布设，用于驱动光学镜头20的驱动器和用于驱动感光组件10的驱动器能够共用驱动部件，以充分利用摄像模组300的内部空间，缩减所述摄像模组300的高度尺寸。
相应地，如图1至图3所示，在本申请实施例中，所述感光组件10，包括线路板组件11和镜座12。所述线路板组件11包括线路板111和电连接于所述线路板111的感光芯片112，具体地，所述感光芯片112具有感光区域以及环绕地形成于所述感光区域的非感光区域。相应地，所述镜座12位于所述线路板组件11的上方，所述镜座12具有对应于所述感光芯片112的至少部分感光区域的通光孔121，以使得成像光线抵达所述镜座时能够穿过所述通光孔121并沿着所述感光组件11的感光路径射向所述感光芯片12的所述感光区域。
所述感光芯片112电连接于所述线路板111，以藉由所述线路板111为 所述感光芯片112提供工作所需要的控制电路和电能，以通过自身的感光功能将光信号转换为电信号进行成像。在一个示例中，所述感光芯片112被安装于所述线路板111的上表面，并通过打金线的方式电连接于所述线路板111。当然，在本申请其他示例中，所述感光芯片112还能以其他方式被设置于所述线路板111和/或其他方式电连接于所述线路板111，例如，以芯片倒装的方式贴附于所述线路板111的下表面，对此，并不为本申请所局限。
所述线路板组件11进一步包括支架113和滤光元件114。所述支架113形成于所述线路板111上以用于支撑其他部件，其中，所述支架113具有对应于所述感光芯片112的至少感光区域的光窗。在本申请一个具体的示例中，所述支架113被实施为单独成型的塑料支架，其通过黏着剂附着于所述线路板111的表面，并用于支撑其他部件。当然，在本申请其他示例中，所述支架113还能以其他方式形成于所述线路板111，例如，所述支架113被实施为模塑支架，其通过模塑工艺一体成型于所述线路板111的预设位置，对此，并不为本申请所局限。
所述滤光元件114可被安装于所述支架113上，以被保持于所述感光芯片112的感光路径上，这样，在外界光线穿过所述滤光元件114以抵达所述感光芯片112的过程中，该外界光线中的杂散光能够被所述滤光元件114所过滤，以提高成像质量。值得一提的是，在本申请其他示例中，所述滤光元件114还能够以其他方式被安装于所述支架113上，例如，先在所述支架113上设置滤光元件114支架(未有图示意)，进而将所述滤光元件114安装在所述滤光元件114支架上，也就是，在该示例中，所述滤光元件114可通过其他支撑件被间接地安装于所述支架113上。并且，在本申请的其他示例中，所述滤光元件114还能够被安装于所述摄像模组300的其他位置，例如，所述滤光元件114形成于所述光学镜头20内(例如，作为一层滤光膜附着于所述光学镜头20的某片光学透镜230的表面)，对此，并不为本申请所局限。
为了增加所述感光组件10的底部强度，在本申请的一些示例中，所述线路板组件11进一步包括设置于所述线路板111的下表面的加强板(未有图示意)，例如，可在所述线路板111的下表面设置钢板，以通过所述钢板来加强所述线路板111的强度。相应地，所述加强板可被配置为与所述线路 板111具有相一致的形状和尺寸，以在被叠置于所述线路板111的下表面后，对所述线路板111的整体进行加强。
特别地，在本申请实施例中，所述光学镜头20被实施为分体式镜头，其包括至少两个镜头部分，例如，所述分体式镜头包括两个镜头部分：第一镜头部分21和第二镜头部分22，其中，所述第一镜头部分21包括第一镜筒211和安装于所述第一镜筒211内的至少一光学透镜230，所述第二镜头部分22包括第二镜筒221和被安装于所述第二镜筒221内的至少一光学透镜230，所述第一透镜部分的至少一光学透镜230与所述第二镜头部分22的至少一光学透镜230相互配合以形成可成像光学系统。
本领域普通技术应知晓，对于由所述第一镜头部分21和所述第二镜头部分22形成的可成像光学系统而言，在预定光学透镜230的数量范围内，所述可成像光学系统的有效焦距与光学透镜230的数量成正比，其解像力也与光学透镜230的数量正比。也就是，在预定数量范围内，所述可成像光学系统的有效焦距越大，其所包含的光学透镜230的数量越多；所述可成像光学系统的解像力越好，其所包含的光学透镜230的数量越大。
如前所述，在本申请实施例中，随着移动电子设备的普及，被应用于移动电子设备的用于帮助使用者获取影像的摄像模组300的相关技术得到了迅猛的发展和进步。目前在市场中，期待配置于移动电子设备的摄像模组300实现多倍变焦拍摄功能或长焦拍摄功能，即要求所配置的摄像模组300具有相对较大的有效焦距。这就要求所配置的光学镜头20的可成像光学系统具有相对较大的有效焦距，也就是，所述光学镜头20的可成像光学系统要配置相对更多数量的光学透镜230。
在这样的技术要求下，如果所述分体式镜头被实施为常规的分体式镜头，即，所述第一镜头部分21和所述第二镜头部分22之间具有固定的相对位置关系，则所述分体式镜头将具有相对较大的高度尺寸，进而导致所述摄像模组300整体具有相对较大的高度尺寸，难以满足移动电子设备轻薄化的组装要求。
针对上述技术问题，本申请发明人尝试将所述分体式镜头配置为动态分体式镜头，即，所述第一镜头部分21和所述第二镜头部分22之间的相对位置关系可发生调整，这样，在工作状态下，所述分体式镜头的所述第一镜头 部分21和所述第二镜头部分22被调整至预定位置以形成完整的可成像光学系统，在非工作状态下，所述分体式镜头的所述第一镜头部分21和所述第二镜头部分22相互靠近以缩减其整体高度尺寸进而缩减所述摄像模组300的整体高度尺寸，以满足移动电子设备轻薄化的组装要求。
为此，在本申请实施例中，为所述分体式镜头配置所述驱动组件30，以通过所述驱动组件30驱动所述分体式镜头在工作状态下和非工作状态下进行切换，其中，在工作状态下，所述驱动组件30驱动所述分体式镜头以调整所述分体式镜头的所述第一镜头部分21和所述第二镜头部分22至预定位置以形成完整的可成像光学系统；在非工作状态下，所述驱动组件30驱动所述分体式镜头中所述第一镜头部分21和所述第二镜头部分22相互靠近以缩减其整体高度尺寸进而缩减所述摄像模组300的整体高度尺寸，以满足移动电子设备轻薄化的组装要求。
具体地，如图1至图3所示，在本申请实施例中，所述驱动组件30包括第一驱动元件31，其中，在工作状态下，所述第一驱动元件31被配置为驱动所述第一镜头部分21沿着所述光轴所设定的方向移动以调整所述第一镜头部分21和所述第二镜头部分22至预定位置，其中，在该预定位置，所述第一镜头部分21和所述第二镜头部分22形成的可成像光学系统的有效焦距在预设范围内。
进一步地，如图4所示，在本申请实施例中，所述驱动组件30还包括第二驱动元件32，其中，在工作状态下，所述第二驱动元件32被配置为在由所述第一驱动元件31将所述第一镜头部分21和所述第二镜头部分22调整至该预定位置后，驱动所述第二镜头部分22沿着所述光轴所设定的方向移动以进行光学对焦。特别地，在本申请实施例中，在由所述第二驱动元件32驱动所述第二镜头部分22移动的过程中，所述第一镜头部分21和所述第二镜头部分22形成的光学系统的有效焦距仍保持在该预设范围内。
也就是，在本申请的一个具体示例中，在工作状态下，首先所述第二镜头部分22保持不动，所述第一驱动元件31驱动所述第一镜头部分21沿着所述光轴移动至预定位置，其中，在该预定位置所述第一镜头部分21和所述第二镜头部分22形成的可成像光学系统的有效焦距在预设范围内；接着，所述第一镜头部分21保持不动，所述第二驱动元件32驱动所述第二镜头部 分22沿着所述光轴进行移动以进行光学对焦，其中，特别地，在由所述第二驱动元件32驱动所述第二镜头部分22移动的过程中，所述第一镜头部分21和所述第二镜头部分22形成的光学系统的有效焦距仍保持在该预设范围内。
在本申请实施例中，如图4所示，所述摄像模组300进一步包括安装于所述镜座12的壳体50，所述壳体50具有收容腔51和连通于所述收容腔51的第一开口52，所述光学镜头20被收容于所述壳体50的收容腔51内。特别地，在本申请实施例中，所述第一开口52的孔径大于所述光学镜头20的外径以允许所述光学镜头20通过所述第一开口52伸出或缩回所述收容腔51。
值得一提的是，在本申请其他示例中，所述工作状态的模式还可以被设置为其他类型。例如，在另外一个具体示例中，所述摄像模组300的工作状态为：首先，所述第二镜头部分22保持不动，所述第一驱动元件31驱动所述第一镜头部分21沿着所述光轴移动至预定位置，其中，在该预定位置所述第一镜头部分21和所述第二镜头部分22形成的可成像光学系统的有效焦距在预设范围内；接着，所述第一驱动元件31和所述第二驱动元件32同时驱动所述第一镜头部分21和所述第二镜头部分22沿着所述光轴的同一方向移动以进行光学对焦，通过这样的方式，可提高光学对焦的速率，其中，特别地，在藉由所述第一驱动元件31和所述第二驱动元件32同时驱动所述第一镜头部分21和所述第二镜头部分22沿着所述光轴的同一方向移动的过程中，所述第一镜头部分21和所述第二镜头部分22形成的光学系统的有效焦距仍保持在该预设范围内。
再如，在又一个具体的示例中，所述摄像模组300的工作状态为：首先，所述第二镜头部分22保持不动，所述第一驱动元件31驱动所述第一镜头部分21沿着所述光轴移动至预定位置，其中，在该预定位置所述第一镜头部分21和所述第二镜头部分22形成的可成像光学系统的有效焦距在预设范围内；接着，所述第一镜头部分21保持不动，所述第二驱动元件32驱动所述第二镜头部分22沿着所述光轴进行移动以进行光学变焦。也就是，在该工作模式下，在由所述第二驱动元件32驱动所述第二镜头部分22移动的过程中，所述第一镜头部分21和所述第二镜头部分22形成的光学系统的有效焦 距发生改变。
应可以理解，在本申请其他示例中，所述摄像模组300的工作状态模式还可以被设置为其他类型，对此，并不为本申请所局限。
相应地，在非工作状态下，所述第一驱动元件31和/或所述第二驱动元件32驱动所述第一镜头部分21和/或所述第二镜头部分22相互靠近，以使得所述第一镜头部分21和所述第二镜头部分22整体所占的尺寸缩减。例如，在一个具体的示例中，所述非工作状态为：所述第二镜头部分22保持不动，所述第一驱动元件31驱动所述第一镜头部分21靠近所述第二镜头部分22，以缩减所述第一镜头部分21和所述第二镜头部分22之间的距离。
值得一提的是，为了尽可能地缩减所述分体式镜头在非工作状态下的整体高度尺寸，优选地，在本申请实施例中，在所述第一镜头部分21和所述第二镜头部分22所形成的光学系统中，所述第一镜头部分21中位于最下部的光学透镜230与所述第二镜头部分22中位于最上部的光学透镜230之间的距离最大。也就是，在所述光学镜头20所形成的可成像光学系统中，在具有最大间隙的两片光学透镜230之间作划分以将所述可成像光学系统分成两个子光学系统部分：所述第一镜头部分21具有第一子光学系统，所述第二镜头部分22具有第二子光学系统。这样，在非工作状态下，所述第一镜头部分21和所述第二镜头部分22可尽可能地靠近，以最大程度地缩减所述光学镜头20在非工作状态下的整体高度尺寸。
当然，在本申请实施例中，还可以采用其他方式对所述光学镜头20所形成的可成像光学系统进行划分，对此，并不为本申请所局限。
值得一提的是，在本申请实施例中，当处于工作状态时，所述第一镜头部分21和所述第二镜头部分22之间的间隙达到完整光学设计所需的间隙。当处于非工作状态时，所述第一镜头部分21和所述第二镜头部分22相互靠近，在此状态下，所述第一镜头部分21和所述第二镜头部分22之间可完全地分离，或者，所述第一镜头部分21和所述第二镜头部分22之间可部分地接触，以具有不连续的间隙，对此，并不为本申请所局限。
进一步地，如图5至图8所示，在本申请实施例中，所述驱动组件30进一步包括第三驱动元件33，所述第三驱动元件33被配置为驱动所述感光组件10在垂直于所述光轴的平面内移动以进行光学防抖。在具体实施例中， 所述第三驱动元件33可驱动所述感光组件10整体在垂直于所述光轴的平面内移动以进行光学防抖，或者，所述第三驱动元件33仅驱动所述感光芯片112在垂直于所述光轴的平面内移动以进行光学防抖，对此，并不为本申请所局限。
本申请发明人尝试通过对驱动元件的选型和合理布设来满足摄像模组300的尺寸需求。在本申请实施例中，所述第一驱动元件31和所述第二驱动元件32在所述摄像模组300的高度方向上并列地设置，且所述第二驱动元件32位于所述第一驱动元件31的内侧，通过这样的位置设置，有利于所述第一驱动元件31和所述第二驱动元件32在所述壳体50内的最小化布局。并且，所述第一驱动元件31为压电致动器、所述第二驱动元件32为电磁式致动器，因此，所述第一驱动元件31和所述第二驱动元件32之间也不会发生干扰。并且，在本申请实施例中，所述第一镜头部分21需配置较大的行程，所述第二镜头部分22的行程相对较小，因此，为所述第一镜头部分21配置压电致动器，同时为所述第二镜头部分22配置电磁式致动器也能满足两者的行程需求。
所述第一驱动元件31包括具有第一镜头安装腔301的第一驱动载体311和用于驱动所述第一驱动载体311的驱动主体312。所述第一镜头部分安装于所述第一镜头安装腔301内。值得一提的是，在本申请实施例中，以所述第一镜头部分21包含镜筒为示例，应可以理解，在本申请其他示例中，所述第一镜头部分21也可以不配置所述第一镜筒211，而将所述第一驱动载体311作为所述第一镜头部分21的至少一光学透镜230的承载部件。也就是，在本申请其他示例中，所述第一镜头部分21仅包含至少一光学透镜230，所述至少一光学透镜230被安装于第一驱动载体311的第一镜头安装腔301内。
值得一提的是，优选地，在本申请实施例中，所述第一驱动载体311的上端部的外径等于所述第一开口52的内径，以使得所述第一驱动载体311被卡设于所述第一开口52内。也就是，所述第一驱动载体311被紧密地契合于所述第一开口52内，并且，更优选地，所述第一开口52与所述第一驱动载体311的上端部具有相一致的形状，以通过这样的方式来提高所述壳体50的密封性能，防止灰尘、水汽等杂物通过所述第一驱动载体311与所述第一开口52之间的间隙进入所述壳体50的内部。更优选地，为了进一步提高 所述摄像模组300的密封性，进一步将所述第一镜头安装腔301的上部密封，例如，在所述第一镜头安装腔301上设置可透光盖板40(例如，玻璃盖板)，以通过所述可透光盖板40防止灰尘、水汽等杂物通过所述第一镜头安装腔301进入所述第一驱动载体311的内部。
特别地，在本申请实施例中，所述第二驱动元件32和所述第三驱动元件33均被实施为电磁式致动器，并且，所述第二驱动元件32和所述第三驱动元件33上下相邻设置，且所述第二驱动元件32和所述第三驱动元件33共用至少一磁石，以充分利用摄像模组300的内部空间，缩减所述摄像模组300的高度尺寸。

值得一提的是，虽然在如图1至图3所示意的示例中，以所述第二镜头部分22包含镜筒为示例，但本领域普通技术人员应知晓，在本申请其他示例中，所述第二镜头部分22也可以不配置所述第二镜筒221而选择将所述第二驱动载体321作为其承载部件。也就是，在本申请其他示例中，所述第二镜头部分22仅包含至少一光学透镜230，所述至少一光学透镜230被安装于所述第二驱动载体321的第二镜头安装腔302内。
所述第三驱动元件33包括第三驱动载体331、设置于所述第三驱动载体331的底部和对应于所述第三线圈332的第三磁石333，所述感光组件10被安装于所述第三驱动载体331上。所述第三磁石333和所述第三线圈332可驱动所述第三驱动载体331在垂直于所述光轴的平面内移动以带动所述感光组件10在垂直于所述光轴的平面内移动。

在本申请实施例中，所述第三磁石333和所述第二磁石323为同一磁石。也就是，所述第二磁石323或所述第三磁石333不仅可与所述第二线圈322配合以驱动所述第二镜头部分22沿着所述光轴所设定的方向移动，而且可与所述第三线圈332配合以驱动所述感光组件10在垂直于所述光轴的平面内移动。
值得一提的是，所述第二驱动元件32和第三驱动元件33包括的磁石和线圈的数量并不为本申请所局限，例如，每一个磁石和一个线圈为一组，所述第二驱动元件32包括的磁石和线圈的组数为1，2，或者更多，所述第三驱动元件33包括的磁石和线圈的组数为1，2，或者更多。
在本申请的一个具体示例中，所述第三驱动元件33包括四组磁石和线圈。在该具体示例中，如图5和图6所示，所述第三磁石333和所述第三线圈332位于所述第三驱动载体331的第一侧，且所述第三磁石333和所述第三线圈332被配置为驱动所述第三驱动载体331在垂直于所述光轴的平面内以第一方向进行移动。

值得一提的是，在该具体示例中，通过增大所述第二驱动元件32和所述第三驱动元件33的共用磁石的高度的方式使得所述共用磁石同时配合所述第二驱动元件32和所述第三驱动元件33的其他部件以驱动所述第二镜头部分22和所述感光组件10移动。
具体地，所述第三线圈332、所述第四线圈334、所述第五线圈336和所述第六线圈338位于同一水平面，即，被安装于同一平面上，分别与所述第三线圈332、所述第四线圈334、所述第五线圈336和所述第六线圈338对应的所述第三磁石333、所述第四磁石335、第五磁石337、第六磁石339的底面位于同一水平面，由于所述第三磁石333的高度高于所述第四磁石335、第五磁石337、第六磁石339的高度，所述第三磁石333的顶面高于所述第四磁石335、第五磁石337、第六磁石339的顶面，并高于或等于所述第二线圈322在其未被导通时的顶部的高度，以同时配合位于所述第三驱动载体331的底部的所述第三线圈332和位于与所述第三驱动载体331的上下相邻的所述第二驱动载体321的侧部的所述第二线圈322。
在本申请实施例的变形实施方式中，也可以通过其他方式使得所述第二驱动元件32和所述第三驱动元件33的共用磁石同时配合所述第二驱动元件32和所述第三驱动元件33的其他部件以驱动所述第二镜头部分22和所述感 光组件10移动，对此，并不为本申请所局限。例如，所述第三线圈332的安装平面高于所述第四线圈334、所述第五线圈336和所述第六线圈338的安装平面，相应地，所述第三磁石333的底面高于所述第四磁石335、第五磁石337、第六磁石339的底面。并且，所述第三磁石333的高度等于所述第四磁石335、第五磁石337、第六磁石339的高度，这样，所述第三磁石333的顶面高于所述第四磁石335、第五磁石337、第六磁石339的顶面，并高于或等于所述第二线圈322在其未被导通时的顶部的高度，以同时配合位于所述第三驱动载体331的底部的所述第三线圈332和位于与所述第三驱动载体331的上下相邻的所述第二驱动载体321的侧部的所述第二线圈322。
值得一提的是，所述第二驱动元件32和所述第三驱动元件33共用的磁石的数量并不为本申请所局限。例如，在本申请的其他具体示例中，位于所述第三驱动载体331的第一侧的所述第三磁石333和位于所述第三驱动载体331的与所述第一侧相对的第二侧的第四磁石335均为所述第一驱动元件31和所述第二驱动元件32的共用磁石。相应地，所述第二驱动元件32包括与所述第四磁石335对应的另一第二线圈322，所述另一第二线圈322和所述第四磁石335被配置为驱动所述第二驱动载体321沿着所述光轴所设定的方向移动以带动被安装于所述第二镜头安装腔302内的所述第二镜头部分22沿着所述光轴所设定的方向移动。
进一步地，所述第二驱动元件32位于所述第一驱动元件31和所述第三驱动元件33之间，为了限制所述第二镜头部分22向上移动的高度并防止所述第一镜头部分21与所述第二镜头部分22发生碰撞，在本申请实施例中，所述摄像模组300进一步包括设置于所述第一驱动元件31和所述第二驱动元件32之间的限位隔离部件34，其中，所述限位隔离部件34为配置为限制所述第二镜头部分22向上移动的最大高度。应注意到，所述限位隔离部件34被设置于所述第一镜头部分21和所述第二镜头部分22之间，因此，其也能防止所述第一镜头部分21与所述第二镜头部分22发生串扰，例如，发生碰撞等。

并且，在本申请实施例中，所述滚珠-滑槽结构60的设置位置并不为本申请所局限，其可设置于所述第三驱动载体331和所述镜座12的四个角落处，也可以设置在其他位置。优选地，在该示例中，沿着第一方向延伸的一对所述滚珠-滑槽结构60相对于所述第三驱动载体331的中心线对称地布置，沿着第二方向延伸的一对所述滚珠-滑槽结构60相对于所述第三驱动载体331的中心线也对称地布置，以提高所述第三驱动载体331的驱动平稳度，即光学防抖的平稳度。
更具体地，在本申请实施例中，每一所述滚珠-滑槽结构60包括设置于所述第三驱动载体331和所述镜座12之间的至少一滑槽和被容纳于所述至少一滑槽的至少一滚珠。并且，在本申请实施例中，所述至少一滑槽的形状不为本申请所局限，其可被实施为“十”字型、矩形等。应可以理解，所述 滑槽的形状引导着所述感光组件10的移动，因此，优选地，所述滑槽包含沿着X轴延伸的部分和/或沿着Y轴延伸的部分。
综上，基于本申请实施例的摄像模组300被阐明，其中，所述摄像模组300在时间分布上错开直立式摄像模组300在整体高度尺寸和较大有效焦距之间的矛盾。具体地，在不工作状态下所述摄像模组300具有相对较小的高度尺寸，在工作状态下所述摄像模组300具有相对较大的有效焦距，以在不工作状态满足终端设备对于摄像模组300的整体高度尺寸的需求，在工作状态下满足摄像模组300的较大有效焦距的需求。并且，通过对驱动器合理布设，用于驱动感光组件10的驱动器和用于驱动镜头部分的驱动器能够共用驱动部件，以充分利用摄像模组300的内部空间，缩减所述摄像模组300的高度尺寸。
