具体实施方式
下面将结合本申请实施例中的附图，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，本领域普通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。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的摄像头模组进行详细地说明。
如图1至图10所示，所述摄像头模组包括：
镜头组件101；
第一电路板102，所述第一电路板102上设置有成像芯片1021；
承载件103，所述承载件包括连接件1031和与所述连接件1031连接的承载板1032，所述承载板1032与所述第一电路板102连接，所述连接件1031与所述镜头组件101活动连接；
驱动机构，所述驱动机构与所述承载件103连接，所述驱动机构用于驱动所述承载件103移动，以带动所述成像芯片1021向靠近或远离所述镜头组件101的方向移动；
其中，所述连接件1031的延伸方向与所述承载件103的移动方向平行。
另外，第一电路板102可以为柔性电路板。如图3所示，第一电路板102上还可以设置有马达驱动芯片及辅助电子元件1022。成像芯片1021、马达驱动芯片及辅助电子元件1022可以焊接在第一电路板102上。马达驱动芯片及辅助电子元件1022可以提供电流驱动线圈104。
其中，镜头组件101可以包括镜头1011和壳体1012，镜头1011可以包括将光线汇聚在成像芯片1021上的透镜，壳体1012可以用于固定镜头1011，并可以用于保护马达内部结构。成像芯片1021可以用于将光信号转换为电信号。
需要说明的是，由于目前终端的机型均搭载大底芯片来获得更高的图像质量，能够带给消费者更好的体验。但大底芯片必须和更大的镜头1011搭配使用，为了匹配更高分辨率的芯片，镜头1011中镜片的数量不断增加，同时为了更好的成像效果会采用折射率更高的玻璃镜片替代原有的塑胶镜片，导致镜头1011的重量不断增加。由于相关技术中采用马达推动镜头1011，在实现对焦的过程中需要马达产生更大的推力，推力来源于电能，从而导致了马达功耗增加，驱动镜头1011的功耗也越来越高。本实施例通过驱动机构驱动承载件103移动，以带动成像芯片1021向靠近或远离所述镜头组件101的方向移动，能够降低摄像头的功耗。
本申请实施例中，采用移动成像芯片1021的方式替代相关技术中移动镜头1011的方式实现对焦。摄像头对焦的本质是镜头1011和成像芯片1021之间的距离发生变化。相关技术中自动对焦摄像头的运动部件为马达以及所带动的镜头1011，成像芯片1021及其他光学部件保持不动，通过马达推动镜头1011调节镜头1011到成像芯片1021的距离，从而实现在不同距离下都可以对焦清晰的效果。本实施例中，将镜头1011和马达作为固定部件，通过调节成像芯片1021到镜头1011的距离实现自动对焦的效果，镜头1011保持静止不动，能够提升可靠性。相对于相关技术中镜头组件101上下移动的方案，摄像头保护盖上需开设较大的丝印开窗，同时壳体1012开窗也较大，本实施例可以减少丝印开窗，且镜头组件101的外壳可做小开孔遮住内部组件，镜头1011可无需做“蘑菇头”，能够改善美观度。
本实施例中，摄像头模组中的镜头1011是固定的，通过改变成像芯片1021和镜头组件101的相对位置实现对焦，可以较大程度上降低功耗，因此成像芯片1021可以搭配更大规格的镜头1011。镜头1011不需要预留和屏幕或者电池后盖上的防尘泡棉的空间，镜头1011可以直接接触防尘泡棉，提升了防尘效果，也有利于整机设计得更薄，能够给用户更好的视觉和手感；对于超广角摄像头，可以加上遮丑的“蘑菇头”，可以更大程度地遮挡壳体1012以及镜头1011和壳体1012之间的间隙，提升整机的精致度。本实施例的摄像头模组可以实现降低马达功耗、规避摄像头异响、降低镜头1011撞击电子设备内部结构风险、提升摄像头模组防尘等级等效果。
另外，第一电路板102上还可以设置有马达驱动芯片及辅助电子元件1022。成像芯片1021、马达驱动芯片及辅助电子元件1022可以焊接在第一电路板102上。马达驱动芯片及辅助电子元件1022可以提供电流驱动线圈104。

可选的，如图5所示，所述驱动机构包括线圈104和磁性件105，所述线圈104或所述磁性件105中的一者与所述连接件1031连接，所述线圈104或所述磁性件105中的另一者与所述镜头组件101连接；
其中，在所述线圈104通电且电流方向为第一电流方向的情况下，所述线圈104或所述磁性件105用于驱动所述承载件103移动，以带动所述成像芯片1021向靠近所述镜头组件101的方向移动；
在所述线圈104通电且电流方向为第二电流方向的情况下，所述线圈104或所述磁性件105用于驱动所述承载件103移动，以带动所述成像芯片1021向远离所述镜头组件101的方向移动。
其中，在所述线圈104连接所述连接件1031的情况下，所述磁性件105与所述镜头组件101连接，所述磁性件105相较于所述线圈104更靠近所述镜头组件101的轴线，所述线圈104驱动所述承载件103移动，以带动所述成像芯片1021向靠近或远离所述镜头组件101的方向移动；在所述磁性件105连接所述连接件1031的情况下，所述线圈104与所述镜头组件101连接，所述线圈104相较于磁性件105更靠近所述镜头组件101的轴线，所述磁性 件105驱动所述承载件103移动，以带动所述成像芯片1021向靠近或远离所述镜头组件101的方向移动。磁性件105可以与线圈104构成驱动马达，驱动所述承载件103移动，以带动所述成像芯片1021向靠近所述镜头组件101的方向移动。磁性件105可以用于产生磁场，示例地，磁性件105可以为磁铁。第一电流方向和第二电流方向可以为相反的电流方向。
需要说明的是，磁性件105相对壳体1012可以固定设置，可以相邻设置其他摄像头的具有磁性件105的马达，能够减少空间占用；且采用线圈104通电进行驱动，相对于其他驱动部件，线圈104重量较轻，能够进一步降低摄像头功耗。
另外，第一电路板102上的辅助电子元件可以包括霍尔传感器，霍尔传感器可以作为位置反馈元件，感应磁性件105的磁场强度，霍尔传感器所在的位置不同，感应到的磁场强度不同，霍尔传感器感应到的磁场强度可以表征成像芯片1021相对于镜头组件101的位置。
该实施方式中，通过线圈104和磁性件105驱动所述承载件103移动，以带动所述成像芯片1021向靠近或远离所述镜头组件101的方向移动，线圈104重量较轻，能够进一步降低摄像头功耗。
可选的，在所述线圈104连接所述连接件1031的情况下，所述磁性件105相较于所述线圈104更靠近所述镜头组件101的轴线。
其中，所述镜头组件101的轴线可以是镜头组件101的中心线。线圈104可以通过绕线或点胶的方式固定在连接件1031上。线圈104可以通过焊接的方式与第一电路板102实现电性连接。线圈104可以直接绕制在承载件103上，且可以通过焊接工艺与第一电路板102连接，无需设置电路板二次引出，有利于提高可靠性和精简工艺。
该实施方式中，所述线圈104连接所述连接件1031，所述磁性件105相较于所述线圈104更靠近所述镜头组件101的轴线，这样，磁性件105相较于所述线圈104更靠近所述镜头组件101的轴线，具有较低的磁漏，能够为多摄像头布局提供更多的设计自由度。
可选的，所述连接件1031设置于所述承载板1032的一端，所述连接件1031位于所述线圈104与所述磁性件105之间。

该实施方式中，所述连接件1031与所述固定件107通过导向件108滑动连接，从而承载件103较易在线圈104的带动下与固定件107发生相对运动，以带动所述成像芯片1021向靠近或远离所述镜头组件101的方向移动。
可选的，所述连接件1031的两端设置有第一导向槽，所述固定件107的外侧设置有与所述第一导向槽配合的第二导向槽，所述导向件108为滚珠，所述滚珠位于所述第一导向槽与所述第二导向槽形成的容置腔内。

该实施方式中，所述第一电路板102、承载件103及所述驱动机构均设置于所述容纳腔内，所述密封板110用于密封所述容纳腔，构成了较为封闭的电磁屏蔽结构，能够提高摄像头的性能。
另外，摄像头模组还可以包括滤光片111，滤光片111可以位于承载件103与第一电路板102之间，滤光片111可以与承载板1032固定连接，示例地，滤光片111可以通过点胶的方式与承载板1032固定。滤光片111可以为 红外截止滤光片，用于截止红外光通过。滤光片111与承载件103固定连接，无需固定滤光片111支架与镜头1011或成像芯片1021间的台阶，可以降低摄像头模组Z向高度，Z向可以为承载件103的移动方向。且移动过程中的碰撞位置与滤光片111顶面具有较远的距离，具有更有效的防尘结构。
作为一种具体的实施方式，摄像头模组可以包括活动单元和固定单元，活动单元可以整体移动，与固定单元相对运动。活动单元可以包括成像芯片1021、承载成像芯片的第一电路板、第二电路板、磁轭件及承载件。固定单元可以包括密封板、镜头组件及磁性件。在马达处于静止状态时，磁性件吸附磁轭件，可以将整个活动单元拉向磁性件一侧，在磁性件的两侧的轨道上布置有滚珠，活动单元可以紧密贴附在滚珠上，并可以上下运动。在固定于承载件上的线圈通电时，线圈在磁性件的磁场作用下产生安培力，推动活动单元在滚珠上上下运动。这样，第二电路板的第一区域跟随第一电路板上下运动，第二电路板的第三区域发生形变，同时，第二电路板的第二区域与密封板固定，保持不动。从而，成像芯片随着活动单元的运动而运动，实现镜头组件与成像芯片之间的相对运动，实现对焦过程。
本申请实施例提供的摄像头模组包括成像芯片、承载成像芯片的第一电路板、第二电路板及磁轭件、以及被装载在第一电路板上的马达驱动芯片、辅助电子元器件；所述第一电路板之上设置滤光片及其支架。第二电路板可以分为与密封板固定部分、与成像芯片固定及电性接部分、以及连接以上两部分的柔性排线；成像芯片、承载成像芯片的第一电路板、滤光片及承载件通过点胶等方式固定为同一个整体，可以通过电磁驱动的方式在自动对焦的方向上进行运动；镜头通过螺纹、点胶或卡扣等方式与壳体进行组合，能够确保相对位置稳定。
需要说明的是，针对高像素的摄像头模组，其镜头及线圈重量较大，远超成像芯片及其配合组件之和，采用移动成像芯片的方式，可以极大地减小对推力的要求，有利于降低马达功耗；且镜头和马达是相对固定的，可以规避镜头在非拍照状态下撞击壳体，避免产生异响，同时摄像头模组可以组成一个封闭的腔体，避免了灰尘进入摄像头内部，且摄像头内部防尘结构设计会更加合理，能够大幅减少摄像头模组固有灰尘在摄像头模组自动对焦过程 中落到成像芯片表面的机会，从而能够提升摄像头品质。进一步的，所述摄像头模组还可以应用于连续变焦的摄像头，可以将连续变焦和自动对焦的功能组件拆分实现，从而可以降低相关的连续变焦的摄像头模组马达的实现难度。

在本申请的描述中，需要理解的是，术语“纵向”、“径向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“设置”、“连接”应做广义理解。例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连。固定连接可以为焊接、螺纹连接和加紧等常见技术方案。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
