具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合本公开具体实施例及相应的附图对本公开技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有 其他实施例，都属于本公开保护的范围。
以下结合附图，详细说明本公开各个实施例公开的技术方案。
如图1-图6所示，本公开实施例公开一种摄像头模组，其具体可以包括支架110、镜头120、图像传感器130、传感器承载部140、电路板150和驱动机构。
镜头120安装于支架110上，该镜头120相对于支架110固定不动，其具体可以包括镜筒以及安装在镜筒内的若干镜片，该镜头120可以聚焦光线，以便于成像。电路板150与支架110相连接，该电路板150可以位于支架110背离镜头120的一侧，两者可以形成安装空间。图像传感器130通过传感器承载部140设置于支架110内，具体地，图像传感器130和传感器承载部140均位于前文所述的安装空间内，图像传感器130安装在传感器承载部140上。图像传感器130与镜头120相对设置，经过镜头120的光线可以照射到图像传感器130上，图像传感器130可以将光信号转化为电信号，该电信号可以通过电路板150输出。
驱动机构设置于支架110内，该驱动机构与传感器承载部140相连，以通过传感器承载部140驱动图像传感器130相对于镜头120移动，从而实现对焦的目的。该驱动机构可以是驱动电机等结构，本公开实施例中，为了简化驱动机构的结构，该驱动机构可以包括线圈160和磁性件170，支架110和传感器承载部140中，一者设置线圈160，另一者设置磁性件170。具体地，可以在支架110上设置线圈160，在传感器承载部140上设置磁性件170，也可以在支架110上设置磁性件170，在传感器承载部140上设置线圈160。这里的磁性件170具体可以是磁铁。可选地，线圈160可以直接与电路板150电连接。当线圈160通电后，线圈160周围将产生磁场，该磁场与磁性件170自身的磁场相作用，即可在线圈160和磁性件170之间产生磁吸力和磁斥力，进而向传感器承载部140施加作用力，以此通过传感器承载部140驱动图像传感器130相对于镜头120靠近或者远离，从而实现对焦的目的。
传感器承载部140和图像传感器130的移动幅度可以根据拍摄需求确定，可以通过改变线圈160内电流大小的方式调整传感器承载部140受到的作用力的大小，从而使传感器承载部140和图像传感器130移动至预定位置处。 如图5所示，在第一状态下，传感器承载部140与电路板150相贴合，图像传感器130与镜头120之间的距离最大；如图6所示，在第二状态下，传感器承载部140在线圈160和磁性件170的作用下脱离电路板150，从而带动图像传感器130移动，使得图像传感器130与镜头120之间的距离缩小。
由于上述驱动机构设置于支架110的内部，因此驱动机构基本不会额外占用支架110外部的空间，使得整个摄像头模组占用的空间更小。
另外，为了提高成像质量，摄像头模组还可以包括滤光片180，支架110朝向镜头120的一面设有第三凹槽112，该滤光片180设置于该第三凹槽112内，且该滤光片180位于镜头120和图像传感器130之间。该滤光片180可以过滤一部分波长的光线，从而提高成像质量。
一种可选的实施例中，支架110的内表面开设环形槽111，该环形槽111内设有线圈160。此时，线圈160可以设置成环形结构，磁性件170被线圈160包围，使得线圈160所产生的磁场可以更大范围地覆盖磁性件170，从而增加线圈160和磁性件170之间的作用力，更可靠地推动传感器承载部140和图像传感器130运动。另外，线圈160设置于环形槽111内以后，线圈160占用的空间更小，整个摄像头模组的尺寸可以进一步缩小，使得摄像头模组占用的空间更小。
当线圈160设置于上述环形槽111内时，磁性件170即设置于传感器承载部140上。为了使线圈160和磁性件170之间产生的作用力更大，可以使磁性件170与线圈160之间的距离尽量小。具体地，传感器承载部140具有朝向环形槽111的外侧面141，该外侧面141上设置有磁性件170。
进一步的实施例中，可以将磁性件170的数量设置为多个，多个磁性件170沿着环绕图像传感器130的方向间隔排布。如此设置后，一方面可以增加线圈160和磁性件170之间所产生的作用力，另一方面可以使得所产生的作用力均匀地分布在传感器承载部140和图像传感器130的周围，使得传感器承载部140和图像传感器130相对于镜头120运动时更加稳定。
为了简化磁性件170的结构，可以将磁性件170设置为条状结构。进一步地，传感器承载部140的外侧面141上可以设置多个第一凹槽142，多个磁性件170一一对应地设置于多个第一凹槽142内。设置第一凹槽142后， 磁性件170的至少一部分相对于传感器承载部140的外侧面141凹陷，使得磁性件170占用的空间更小，整个摄像头模组的尺寸可以进一步缩小，使得摄像头模组占用的空间更小。
为了进一步增加传感器承载部140和图像传感器130移动时的稳定性，摄像头模组还可以包括弹性件190，该弹性件190的一侧表面与支架110相抵靠，弹性件190的另一侧表面与传感器承载部140相抵靠。该弹性件190受力后可以发生变形，进而向传感器承载部140施加反作用力，该反作用力可以实现传感器承载部140的预压，使得传感器承载部140运动时不容易出现偏斜，从而提高成像质量。
更进一步地，该弹性件190的数量可以设置为多个，多个弹性件190沿着环绕图像传感器130的方向间隔排布。随着弹性件190的数量的增加，弹性件190与传感器承载部140之间的作用点更多，作用点的分布范围更广，以此更好地防止传感器承载部140运动时出现偏斜，使得传感器承载部140和图像传感器130移动时更加平稳。
可以理解地，图像传感器130可以与电路板150电连接，继而使其可以被电路板150驱动，并且与电路板150之间进行信号传输。图像传感器130可以通过传感器承载部140或者其他额外增设的结构与电路板150电连接，但是考虑到图像传感器130会相对于镜头120移动，因此为了提升图像传感器130与电路板150之间的电连接的可靠性，可以将至少一部分弹性件190设置为导电件，也就是说，至少一部分弹性件190不仅可以发生弹性变形，还具有导电性。由于该导电件与传感器承载部140和支架110均有接触关系，因此，该导电件可以通过支架110与摄像头模组的电路板150电连接，且图像传感器130可以通过传感器承载部140与导电件电连接，最终实现图像传感器130与电路板150之间的电连接。由于图像传感器130和传感器承载部140同步移动，且传感器承载部140与导电件、导电件与支架110可以始终保持接触关系，支架110和电路板150又相对静止，因此图像传感器130与电路板150之间的电连接将更加可靠。
可选的实施例中，摄像头模组还可以包括定位件210，该定位件210设置于传感器承载部140与支架110之间，传感器承载部140和支架110通过 该定位件210定位配合。当传感器承载部140相对于支架110移动时，定位件210可以使传感器承载部140的移动路径趋近于直线。无论传感器承载部140相对于镜头120移动到何种位置，图像传感器130相对于镜头120都可以尽量保持在预定位置处，而基本不会发生偏移，使得摄像头模组的成像质量更高。
当支架110的内表面开设环形槽111时，该环形槽111的一部分可延伸至支架110的内表面，另一部分则不延伸至支架110的内表面，使得线圈160的一部分相对于支架110的内表面露出，另一部分隐藏，从而预留支架110的一部分结构，以供该部分结构与定位件210配合。
可选地，上述定位件210可以设置成定位滚珠，该定位滚珠与支架110以及传感器承载部140滚动配合，当传感器承载部140相对于支架110移动时，定位滚珠可以滚动，进而减小定位滚珠与支架110以及传感器承载部140之间的磨损，使得传感器承载部140和支架110相对运动时可以长时间地保持相对较高的运动精度。进一步地，该定位滚珠的数量为多个，多个定位滚珠沿着环绕传感器承载部140的方向间隔排布。如此设置可以增加传感器承载部140和支架110之间的定位点，两者之间的定位精度更高。
为了使定位滚珠更稳定地与传感器承载部140配合，可以在传感器承载部140的角部设有直角形凹槽143，定位滚珠设置于该直角形凹槽143内。这里的直角形凹槽143具有相互垂直的两个内表面，定位滚珠的两部分分别与该两个内表面相接触，从而使得定位滚珠更加稳定地保持在该直角形凹槽143内。一种具体的实施例中，传感器承载部140大致为矩形结构，其具有四个角部，每个角部均设置直角形凹槽143，每个直角形凹槽143内均设置至少一个定位滚珠。
可选的实施例中，传感器承载部140朝向镜头120的一面设有第二凹槽144，图像传感器130设置于该第二凹槽144内。此时，图像传感器130相对于传感器承载部140凹陷，因此图像传感器130占用的空间更小，整个摄像头模组占用的空间更小。同时，镜头120与图像传感器130之间的距离有所增大，使得图像传感器130相对于镜头120的移动幅度更大，以此满足更多种拍摄需求。
基于上述任一实施例所述的摄像头模组，本公开实施例还公开一种移动终端，该移动终端包括上述任一实施例所述的摄像头模组。
本公开实施例所公开的移动终端可以为智能手机、平板电脑、电子书阅读器或可穿戴设备。当然，该移动终端也可以是其他设备，本公开实施例对此不做限制。
本公开上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本公开的实施例而已，并不用于限制本公开。对于本领域技术人员来说，本公开可以有各种更改和变化。凡在本公开的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本公开的权利要求范围之内。
