技术领域
本申请涉及终端技术领域，特别涉及一种摄像模组及马达结构、电子设备。
背景技术
随着手机摄像头技术的发展，手机等消费电子产品，如手机、平板、笔记本电脑以及穿戴摄像头等，拍照的效果以及需求越来越与单反相机看齐，而摄像功能效果也已逐渐成为终端电子设备的重要特征以及评价终端电子设备性能的主要指标之一。
目前的电子设备以手机为例，其摄像模组通常包括有镜头以及驱动马达，其中驱动马达是摄像模组中实现变焦和对焦的载体，通常镜头固定在驱动马达上，在驱动马达产生的推动力的作用下，镜头移动到指定的位置上，从而实现不同倍率下的变焦和对焦。
然而，当摄像模组包括的可动镜群为多个，以满足更高拍摄质量的变焦模式，如连续变焦模式等时，现有的驱动结构较为复杂，影响镜头的运动速度和精准度，降低了变焦效果。
发明内容
本申请提供一种摄像模组及马达结构、电子设备，解决了现有的摄像模组中驱动结构较为复杂，影响镜头的运动速度和精准度降低拍摄效果的问题。
本申请实施例的第一方面提供一种摄像模组，包括马达结构和摄像组件，所述马达结构包括基架、驱动装置、承载体，所述驱动装置设置在所述基架上，所述承载体与所述驱动装置连接；
所述摄像组件包括镜头和镜头导杆，所述镜头导杆设置在所述基架上，所述镜头与所述镜头导杆滑动连接，且所述镜头设置在所述承载体上。
这样驱动装置驱动承载体运动时，就能够带动镜头沿着镜头导杆移动，实现镜头的变焦或对焦等。与现有的摄像组件相比，驱动装置与承载体连接，镜头设置在承载体上，且镜头在驱动装置的作用下沿镜头导杆移动，也可以理解为，将驱动装置设置在镜头上使驱动装置和镜头耦合成一个整体，并通过驱动装置带动镜头沿着镜头导杆移动，与现有的马达结构相比，省去了供承载体移动的滑轨，简化了镜头的运动系统，有效的降低了镜头滑动的摩擦力，简化了摄像模组中镜头的运动系统，从而提高了镜头运动的速度和精准度，有助于提升拍摄效果。
另外，简化镜头运动系统的摄像模组，布局更加简单，具有更好的可实现性，同 时还具有更低的成本。
在第一方面的一种可能的实现方式中，所述摄像组件为多个，每个所述摄像组件对应一个所述驱动装置和一个所述承载体，且两个摄像组件中，其中一个摄像组件的镜头与另一个摄像组件的镜头导杆滑动连接。
这样可以实现多组镜头的移动，同时通过上述方式简化了镜头的运动系统，显著的提升了镜头运动的速度和精准度。如摄像组件可以为两个，马达结构的基架上设置有两个驱动装置，两个驱动装置分别连接有承载座，每个承载座上设置有一个摄像组件。
在第一方面的一种可能的实现方式中，所述承载体上设置有第一磁性体，所述镜头上设置有第二磁性体，所述第一磁性体和所述第二磁性体相吸。
这样通过第一磁性体和第二磁性体之间的吸引力，就能够将镜头设置在承载体上，实现摄像组件和驱动装置的耦合，从而使驱动装置和镜头的运动基准方式归一化，提高镜头运动速度和精准度。
在第一方面的一种可能的实现方式中，所述承载体和所述镜头的其中一个上设置有卡件，所述承载体和所述镜头的其中另一个上设置有卡槽，所述卡件和所述卡槽定位配合。
这样在镜头上可以设置有卡件，在承载体上可以设置有卡槽，卡件可以和卡槽实现定位配合，实现镜头和承载体的配合连接，同时卡件和卡槽的配合可便于镜头与承载体安装时的定位，便于镜头和承载体的装配。
在第一方面的一种可能的实现方式中，所述驱动装置包括驱动线圈、第一驱动磁体和环形的第一磁屏蔽结构；
所述第一磁屏蔽结构的部分穿过所述驱动线圈的中心，所述第一驱动磁体位于所述第一磁屏蔽结构内并位于所述驱动线圈的一侧，且所述第一驱动磁体的磁感线与所述驱动线圈垂直，所述第一驱动磁体、所述第一磁屏蔽结构与所述承载体固定连接，所述驱动线圈设置在所述基架上。
这样驱动线圈靠近第一驱动磁体的一端就有磁场，同时，驱动线圈通电后会形成环状电流，在垂直的线圈的磁场中就会产生安培力，该安培力就作为驱动力，使第一驱动磁体和第一磁屏蔽结构能够往复穿过驱动线圈运动，第一驱动磁体、第一磁屏蔽结构与承载体固定连接，驱动线圈设置在基架上，这样就能够带动承载体相对基架发生直线移动，进而通过承载体带动其上的镜头沿着镜头导杆移动，实现摄像模组的长行程对焦或变焦等。
在第一方面的一种可能的实现方式中，所述驱动装置还包括与所述第一磁屏蔽结构并列的第二磁屏蔽结构，所述第二磁屏蔽结构的部分穿过所述驱动线圈的中心；
所述第二磁屏蔽结构内设置有第二驱动磁体，所述第二驱动磁体位于所述驱动线圈的一侧，所述第二驱动磁体的磁感线与所述驱动线圈垂直，且所述第一驱动磁体和所述第二驱动磁体的磁感线方向相反，所述第二驱动磁体、所述第二磁屏蔽结构与所述承载体固定连接。
这样驱动线圈靠近第二驱动磁体的一端也会产生磁场，驱动线圈在通电后会形成环状电流，从而在垂直线圈的磁场中产生安培力，该安培力也可以作为驱动力，可以 通过控制第一驱动磁体和第二驱动磁体的磁极方向，使第一驱动磁体和第二驱动磁体的磁感线方向相反，也就使驱动线圈两侧产生同方向的安培力作为驱动力，以驱动承载体直线移动，有效的提升了驱动装置的驱动力，有助于提升镜头运动速度及精准度。
在第一方面的一种可能的实现方式中，所述马达结构还包括位置检测装置，所述位置检测装置用于检测承载体的运动位置。
位置检测装置对承载体运动位置进行检测，也就可以对镜头的运动位置实现检测，从而可以判断镜头应如何运动，或是否已移动到所需位置，以实现对马达结构的闭环控制。
在第一方面的一种可能的实现方式中，所述位置检测装置包括检测部件和感测磁体，所述感测磁体设置在所述承载体上，所述检测部件设置在所述基架上，所述检测部件用于检测所述感测磁体的磁场。
当驱动装置驱动承载体移动时，感测磁体也会随着承载体移动，这样感测磁体和检测部件之间的距离就会发生变化，检测部件检测到的感测磁体的磁场也就会发生变化，通过这种变化即可实现对承载体运动位置的检测，进而实现对镜头运动位置的检测。
本申请实施例的第二方面提供一种马达结构，用于驱动摄像组件移动，包括基架、驱动装置、承载体，所述驱动装置固定设置在所述基架上，所述承载体与所述驱动装置连接，所述承载体用于承载所述摄像组件的镜头，所述驱动装置用于带动所述镜头沿着所述摄像组件的镜头导杆移动。
通过使马达结构包括基架、驱动装置、承载体，其中，驱动装置固定在基架上，承载体与驱动装置连接，承载体用于承载摄像组件的摄像头，驱动装置用于带动镜头沿着摄像组件的镜头导杆移动，即将驱动装置通过承载座与镜头耦合成为一个整体，并通过驱动装置带动镜头沿镜头导杆移动，省去了供承载体移动的滑轨，简化了马达结构，进而简化了镜头的运动系统，从而提高了镜头的运动速度和精准度，提升拍摄效果。
在第二方面的一种可能的实现方式中，还包括滑轨，所述滑轨可拆卸设置在所述基架上，所述承载体滑动设置在所述滑轨上，且当所述承载体承载有所述镜头时，所述滑轨从所述基架上拆卸。
即马达结构上可以通过可拆卸的方式设置有供承载体滑动的滑轨，在将摄像组件与马达结构连接的时候，使镜头承载设置在承载体上时，可以将滑轨从基架上拆卸下来，从而达到简化镜头运动系统的目的。而使马达结构在未承载镜头时，包括有滑轨，驱动装置可以驱动承载体在滑轨上滑动，这样可以便于对马达结构的运动性能进行检测，及时进行检测调整，保证马达结构的驱动效果。
本申请实施例的第三方面提供一种电子设备，包括上述任一所述的摄像模组，或者，包括上述所述的马达结构。
该电子设备通过包括摄像模组或马达结构，其中该摄像模组和马达结构中，由于件驱动装置与镜头耦合，并通过驱动装置带动镜头沿着镜头导杆移动，省去了供承载体移动的滑轨，简化了镜头的运动系统，从而提高了镜头运动的速度和精准度，有助于提升电子设备的拍摄效果，提高电子设备的性能。

具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请，下面将结合附图对本申请实施例的实施方式进行详细描述。
近年来，智能手机等电子设备的拍摄效果越来越成为消费者考量智能手机的重要因素，也成为各家手机厂商争夺市场重要卖点，因此手机摄像模组的性能显得越发重要。其中长焦镜头因优异的远景拍摄效果，深受广大消费者的喜爱。以手机为例，现有的手机长焦摄像模组通常采用潜望式架构设计，相比于定焦的长焦镜头，可连续变焦镜头在AF对焦镜群的基础上增加了ZOOM镜群，含有两组可动镜群，使得整个模组的光学系统更加复杂。
其中，驱动马达是摄像模组实现变焦和对焦的载体，在马达推力的驱动下，镜头随着马达载体的移动到达指定位置，从而实现不同倍率下的变焦和对焦。在连续变焦的模组中，含有一组以上的可动镜群，且镜头的移动行程更大，精度要求也更高。现有的摄像模组中，通常马达结构包括驱动装置、载体和滑轨，驱动装置可驱动载体在其滑轨上移动，其中摄像模组的镜头设置在载体上，同时镜头可滑动的设置在镜头的移动导轨上，驱动装置通过载体就可以驱动镜头沿着其移动导轨移动。然而当多个镜群需要移动时，马达结构内就会出现多导轨的情况，马达结构变得更加的复杂，导致整个摄像模组中镜头运动系统复杂化，从而影响镜头的运动速度和运动精准度，降低拍摄效果。
基于上述技术问题，本申请实施例提供一种摄像模组及马达结构、电子设备，该 摄像模组通过使驱动装置和承载体相连，镜头设置在承载体上，且镜头与镜头导杆滑动连接，驱动装置驱动承载体运动时，能够带动镜头沿着镜头导杆移动，实现镜头的对焦和变焦等，也就是将驱动装置设置在镜头上使驱动装置和镜头耦合呈一个整体，并通过驱动装置带动镜头沿着镜头导杆移动，省去了供承载体移动的滑轨，降低了镜头滑动的摩擦力，简化了摄像模组中镜头的运动系统，从而提高了镜头运动的速度和精准度，有助于提升拍摄效果。
以下结合附图，对本申请实施例提供的一种摄像模组及马达结构、电子设备进行详细的说明。
图1为本申请实施例提供的一种摄像模组的结构示意图。
参见图1所示，本申请实施例提供的一种摄像模组100，包括马达结构10和摄像组件20，其中，马达结构10包括基架11、驱动装置12、承载体13，驱动装置12设置在基架11上，承载体13与驱动装置12连接，这样驱动装置12产生的驱动力就能够带动承载体13发生移动。
摄像组件20包括镜头21和镜头导杆22，镜头导杆22设置在基架11上，镜头21与镜头导杆22滑动连接，且镜头21设置在承载体13上，这样驱动装置12驱动承载体13运动时，就能够带动镜头21沿着镜头导杆22移动，实现镜头21的变焦或对焦等。与现有的摄像组件20相比，驱动装置12与承载体13连接，镜头21设置在承载体13上，且镜头21在驱动装置12的作用下沿镜头导杆22移动，也可以理解为，将驱动装置12设置在镜头21上，使驱动装置12和镜头21耦合成一个整体，并通过驱动装置12带动镜头21沿着镜头导杆22移动，与现有的马达结构10相比，省去了供承载体13移动的滑轨14，简化了镜头21的运动系统，有效的降低了镜头21滑动的摩擦力，简化了摄像模组100中镜头21的运动系统，从而提高了镜头21运动的速度和精准度，有助于提升拍摄效果。
另外，简化镜头21运动系统的摄像模组100，布局更加简单，具有更好的可实现性，同时还具有更低的成本。
其中，摄像组件20可以为多个，每个摄像组件20对应一个驱动装置12和一个承载体13，即一个承载体13上可以设置有一个摄像组件20，该摄像组件20通过一个驱动装置12来驱动，这样可以实现多组镜头21的移动。
其中，在两个摄像组件20中，其中一个摄像组件20的镜头21与另一个摄像组件20的镜头导杆22滑动连接，一个镜头21设置在两个镜头导杆22上，并沿着两个镜头导杆22移动，这样有助于提高镜头21移动的稳定性。
具体的，参见图1所示，摄像组件20包括有两个(结合图9所示)，分别为第一摄像组件和第二摄像组件，其中，第一摄像组件包括第一镜头和第一镜头导杆，第二摄像组件包括第二镜头和第二镜头导杆。第一镜头的一端与第一镜头导杆滑动连接，第一镜头的另一端与第二镜头导杆滑动连接，第二镜头的一端与第二镜头导杆滑动连接，第二镜头的另一端与第一镜头导杆滑动连接，这样第一镜头和第二镜头均沿着第一镜头导杆和第二镜头导杆移动，提升了第一镜头和第二镜头移动的稳定性。
另外，当摄像组件为多个时，即摄像组件中包括有多组需要移动的镜头，使摄像模组的镜头运动系统更加的复杂，而本申请实施例提供的摄像模组通过上述方式可以 简化镜头的运动系统，显著的提升了镜头运动的速度和精准度。
具体的，参见图1所示，以摄像组件20为两个为例，马达结构10的基架11上设置有两个驱动装置12，两个驱动装置12分别连接有承载体13，其中，第一承载体上设置有第一镜头，第二承载体上设置有第二镜头，第一镜头的一端与第一镜头导杆滑动连接，第一镜头的另一端与第二镜头导杆滑动连接，第二镜头的一端与第二镜头导杆滑动连接，第二镜头的另一端与第一镜头导杆滑动连接。与马达结构10上具有滑轨14时相比，具体的，每个滑轨14对应一个承载体13，结合图7所示，包括有第一滑轨和第二滑轨，第一承载体与第一滑轨滑动连接，第二承载体与第二滑轨滑动连接。将马达结构10和摄像组件20装配后，第一镜头的运动就与第一滑轨、第一镜头导杆、第二镜头导杆以及第二滑轨相关，相应的，第二镜头的运动与第二滑轨、第二镜头导杆、第一镜头导杆以及第一滑轨相关，镜头的运动系统较为复杂。
而本申请实施例中，将马达结构10中与承载体相连的滑轨14去掉，这样马达结构10和摄像组件20装配后，第一镜头的运动就与第一镜头导杆和第二镜头导杆相关，第二镜头的运动与第二镜头导杆和第一镜头导杆相关，显著的减少了镜头21滑动的摩擦力，简化了镜头21的运动系统，有效的提高了镜头21运动的速度和精准度。
图2为本申请实施例提供的一种摄像模组中承载体和镜头的装配示意图。
其中，参见图2所示，本申请实施例中，承载体13上设置有第一磁性体131，镜头21上设置有第二磁性体211，第一磁性体131和第二磁性体211相吸，这样通过第一磁性体131和第二磁性体211之间的吸引力，就能够将镜头21设置在承载体13上，实现摄像组件20和驱动装置12的耦合，从而使驱动装置12和镜头21的运动基准方式归一化，提高镜头21运动速度和精准度。
在承载体13和镜头21的其中一个上还可以设置有卡件，在承载体13和镜头21的其中另一个上可以设置有卡槽，具体的，如在本申请实施例中，参见图2所示，在镜头21上可以设置有卡件212，在承载体13上可以设置有卡槽132，卡件212可以和卡槽132实现定位配合，实现镜头21和承载体13的配合连接，同时卡件212和卡槽132的配合可便于镜头21与承载体13安装时的定位，便于镜头21和承载体13的装配。
具体的，卡件212可以是在镜头21朝向承载体13的一面上形成的凸起，卡槽132可以是在承载体13朝向镜头21一面上形成的凹槽。
其中，将镜头21通过上述的第一磁性体131、第二磁性体211、卡件212以及卡槽132的方式设置在承载体13上之后，可以通过胶粘层将镜头21和承载体13进一步的固定，提升镜头21与承载体13的连接强度，保证镜头21的设置稳定性，有助于提升镜头21的拍摄效果。
图3为本申请实施例提供的一种摄像模组的侧视结构示意图。
参见图3所示，本申请实施例中，马达结构10还包括位置检测装置15，位置检测装置15用于检测承载体13的运动位置，也即可以对镜头21的运动位置实现检测，从而可以判断镜头21应如何运动，或是否已移动到所需位置，以实现对马达结构10的闭环控制。
具体的，参见图3所示，位置检测装置15可以包括检测部件151和感测磁体152， 其中，感测磁体152设置在承载体13上，检测部件151设置在基架11上，检测部件151用于检测感测磁体152的磁场。当驱动装置12驱动承载体13移动时，感测磁体152也会随着承载体13移动，这样感测磁体152和检测部件151之间的距离就会发生变化，检测部件151检测到的感测磁体152的磁场也就会发生变化，通过这种变化即可实现对承载体13运动位置的检测，进而实现对镜头21运动位置的检测。
另外，检测部件151设置在基架11上，而驱动装置12的驱动线圈121也可以设置在基架11上，感测磁体152设置在承载座上，这样马达结构10中需要供电的部分就固定设置在基架11上，构成了动磁式马达结构，使马达结构10的结构形态趋于简单化，降低马达结构10的可实现难度。
图4为本申请实施例提供的一种驱动装置的结构示意图，图5为本申请实施例提供的一种驱动装置的局部放大图。
本申请实施例中，参见图4所示，驱动装置12包括驱动线圈121、第一驱动磁体122和环形的第一磁屏蔽结构123，其中，第一磁屏蔽结构123的部分穿过驱动线圈121的中心，第一驱动磁体122位于第一磁屏蔽结构123内，并位于驱动线圈121的一侧。
参见图5所示，第一驱动磁体122通过充磁效应可以形成垂直于驱动线圈121延伸方向(即垂直于驱动线圈121环绕中心线)的磁感线(如图5中B方向)，这样驱动线圈121靠近第一驱动磁体122的一端就有磁场，同时，驱动线圈121通电后会形成环状电流(如图5中I方向)，在垂直的线圈的磁场中就会产生安培力，该安培力就作为驱动力，使第一驱动磁体122和第一磁屏蔽结构123能够往复穿过驱动线圈121运动，第一驱动磁体122、第一磁屏蔽结构123与承载体13固定连接，驱动线圈121设置在基架11上，这样就能够带动承载体13相对基架11发生直线移动，进而通过承载体13带动其上的镜头21沿着镜头导杆22移动，实现摄像模组100的长行程对焦或变焦等。
其中，磁屏蔽结构的成型材料可以是具有优良导磁性的材料。
图6为本申请实施例提供的又一种驱动装置的结构示意图。
参见图6所示，本申请实施例中，驱动装置12还可以包括与第一磁屏蔽结构123并列的第二磁屏蔽结构125，第一磁屏蔽结构123和第二磁屏蔽结构125可以形成双回字型结构，第二磁屏蔽结构125的部分穿过驱动线圈121的中心。第二磁屏蔽结构125内设置有第二驱动磁体124，第二驱动磁体124通过充磁效应形成垂直于驱动线圈121的磁感线，驱动线圈121靠近第二驱动磁体124的一端也会产生磁场，驱动线圈121在通电后会形成环状电流，从而在垂直线圈的磁场中产生安培力，该安培力也可以作为驱动力，可以通过控制第一驱动磁体122和第二驱动磁体124的磁极方向，使第一驱动磁体122和第二驱动磁体124的磁感线方向相反，也就使驱动线圈121两侧产生同方向的安培力作为驱动力，以驱动承载体13直线移动，有效的提升了驱动装置12的驱动力，有助于提升镜头21运动速度及精准度。
结合图1所示，摄像模组100还可以包括有供电装置16，该供电装置16可以与驱动线圈121连接，以给驱动线圈121供电。
图7为本申请实施例提供的一种马达结构的结构示意图，图8为本申请实施例提 供一种马达结构的侧视结构示意图，图9为本申请实施例提供的一种摄像组件的结构示意图。
本申请实施例还提供一种马达结构10，用于驱动摄像组件20移动，以实现摄像的对焦或变焦等。马达结构10和摄像组件20共同装配形成上述的摄像模组100。该马达结构10可以应用于潜望式长焦模组中，用于实现模组的长行程对焦。
具体的，参见图7和图8所示，包括基架11、驱动装置12、承载体13，驱动装置12固定设置在基架11上，承载体13与驱动装置12连接，承载体13用于承载摄像组件20的镜头21，驱动装置12用于带动镜头21沿着摄像组件20的镜头导杆22移动，这样驱动装置12驱动承载体13运动，就能够带动镜头21沿着镜头导杆22移动，实现镜头21的变焦或对焦等，即将驱动装置12通过承载座与镜头21耦合成为一个整体，并通过驱动装置12带动镜头21沿镜头导杆22移动，省去了供承载体13移动的滑轨14，简化了马达结构10，进而简化了镜头21的运动系统，从而提高了镜头21的运动速度和精准度，提升拍摄效果。
其中，参见图7和图8所示，马达结构10还可以包括有滑轨14，滑轨14可以通过可拆卸设置的方式设置在基架11上，承载体13滑动设置在滑轨14上，且当承载体13上承载有镜头21时，滑轨14从基架11上拆卸。也即马达结构10上可以通过可拆卸的方式设置有供承载体13滑动的滑轨14，结合图9和图1所示，在将摄像组件20与马达结构10连接的时候，使镜头21承载设置在承载体13上时，可以将滑轨14从基架11上拆卸下来，从而达到简化镜头21运动系统的目的。
而使马达结构10在未承载镜头21时，包括有滑轨14，驱动装置12可以驱动承载体13在滑轨14上滑动，这样可以便于对马达结构10的运动性能进行检测，保证马达结构10的驱动效果。
其中，马达结构10可以包括有多个滑轨14，多个滑轨14设置在基架11上，每个滑轨14对应一个承载体13和一个驱动装置12，每个承载体13上可以承载至少一组镜头21。这样就可以实现对多组镜头的移动，可适用于长行程变焦模组中，能够有效的简化镜头的运动系统，提高镜头运动的速度和精准度。
结合图7和图9所示，马达结构10的承载体13上可以设置有第一磁性体131，在摄像组件20的镜头21上可以设置有第二磁性体211，第一磁性体131和第二磁性体211相吸，将镜头21设置在承载体13上。
在承载体13上还可以设置有卡槽132，镜头21上可以设置有能够与卡槽132进行定位配合的拉件，以实现镜头21和承载体13的配合连接，这样通过第一磁性体131和第二磁性体211间的吸引力以及卡件212和卡槽132的配合，将镜头21与承载体13固定连接，实现摄像组件20和驱动装置12的耦合。
在将马达结构10和摄像组件20进行装配时，首先通过镜头21和承载体13上分别设置的第一磁性体131和第二磁性体211相吸，并通过镜头21上的卡件212和承载体13上的卡槽132定位配合，使镜头21固定设置在承载体13上。然后可以将镜头21和承载体13通过胶粘层固定，最后抽掉马达结构10中的滑轨14，以简化马达结构10的结构，实现对镜头运动系统的简化。
参见图8所示，马达结构10还可以包括有位置检测装置15，用于检测承载体13 的运动位置，进而对镜头21的运动位置进行检测。
具体的，位置检测装置15可以包括有检测部件151和感测磁体152，其中，感测磁体152可以设置在承载体13上，检测部件151可以设置在基架11上，检测部件151用于检测感测磁体152的磁场，从而根据感测磁体152磁场的变化实现对承载体13运动位置的检测。
在本申请实施例中，马达结构10的驱动装置12可以包括有驱动线圈121、第一驱动磁体122和环形的第一磁屏蔽结构123，其中，第一磁屏蔽结构123的部分穿过驱动线圈121的中心，第一驱动磁体122位于第一磁屏蔽结构123内，并位于驱动线圈121的一侧，第一驱动磁体122的磁感线与驱动线圈121垂直，使驱动线圈121靠近第一驱动磁体122的一端有磁场，驱动线圈121通电后产生的安培力即可作为驱动力，驱动承载体13移动，进而通过承载体13带动其上的镜头21沿着镜头导杆22移动，实现摄像模组100的长行程对焦或变焦等。
驱动装置12还可以包括与第一磁屏蔽结构123并列的第二磁屏蔽结构125，第二磁屏蔽结构125的部分穿过驱动线圈121的中心。第二磁屏蔽结构125内设置有第二驱动磁体124，第二驱动磁体124的磁感线与驱动线圈121垂直，驱动线圈121靠近第二驱动磁体124的一端也会产生磁场，驱动线圈121在通电后会产生安培力，可以通过控制第一驱动磁体122和第二驱动磁体124的磁极方向，使驱动线圈121两侧产生同方向的安培力作为驱动力，以驱动承载体13直线移动，有效的提升了驱动装置12的驱动力，有助于提升镜头21运动速度及精准度。
参见图8所示，摄像模组100还可以包括有供电装置16，该供电装置16可以与驱动线圈121连接，以给驱动线圈121供电。
本申请实施例还提供一种电子设备，该电子设备可以包括但不限于为手机、平板电脑、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、手持计算机、触控电视、对讲机、上网本、POS机、个人数字助理(personal digital assistant，PDA)、可穿戴设备、虚拟现实设备等具有摄像镜头的固定终端或移动终端。
