在具体实施方式中所描述的各个具体技术特征和各实施例，在不矛盾的情况下，可以通过任何合适的方式进行组合，例如通过不同的具体技术特征/实施例的组合可以形成不同的实施方式，为了避免不必要的重复，本实用新型中各个具体技术特征/实施例的各种可能的组合方式不再另行说明。
如图1和图2所示，本实用新型实施例提供一种摄像模块10。摄像模块10可安装于电子设备内部（图6所示），提供拍照或录制视频功能。摄像模块10包括摄像头组件100（本实施例的摄像头组件100为双摄像头组件，在别的实施例中也可以为单摄像头组件或三摄像头组件等多摄像头组件）和与所述摄像头组件100连接并控制所述摄像头组件升降和/或旋转的驱动装置32。如图3所示，本实施例中，驱动装置包括传动组件200和驱动组件300，驱动组件300与传动组件200连接，传动组件200与摄像头组件100连接，传动组件200包括基座210和转轴220，驱动组件300通过传动组件200控制摄像头租组件100升降和旋转。基座210设有与所述转轴220配合的转轴安装孔211，所述转轴220受所述驱动装置32驱动可相对转轴安装孔211转动。
在别的实施例中，驱动装置32还可以为其他的实施方式，驱动装置32也可仅具有转动摄像头组件100的功能，本实用新型在此不做限定。
结合图2至图5所示，图4所示为摄像头组件100与传动组件200的基座210连接的结构示意图；图5所示为图4的A部分的局部放大图。为便于展示基座210的内部结构，对基座210进行了剖面展示。基座210上设有与转轴220配合安装的转轴安装孔211，转轴220受驱动组件300驱动可相对转轴安装孔211转动。
转轴220的侧壁设有至少一个第一磁钢230，转轴安装孔内壁设有至少一个与第一磁钢230磁性相吸的第二磁钢240。在别的实施例中，第一磁钢230可以为一个，相应的第二磁钢240也为一个；而本实施例优选为第一磁钢230和第二磁钢240均为两个，与所述第一磁钢230一一对应设置且与各第一磁钢230均磁性相吸。两个第一磁钢230和第二磁钢相互作用使得转轴220的受力均衡，不易倾斜。摄像头组件100具有一初始状态，在所述初始状态下，第一磁钢230和第二磁钢240相对齐。
本实用新型还提供一种安装了上述摄像模块的电子设备，本实施例的电子设备以手机为例。图6所示为本实施例的摄像模块10安装在手机20上的结构示意图，图中为便于重点说明本申请的技术要点，手机内部的其他零部件均不进行图示，仅以示意图的方式表示手机20。本实施例仅以手机作为示例，本实用新型的摄像模块10当然也可以安装在诸如平板电脑，掌上多媒体娱乐设备（例如MP4、MP5）或其他移动终端等电子设备上。如图6所示，摄像模块10隐藏在手机20内部，手机20上端设有一开口21，以供摄像头组件100升出（即伸出）。而为了尽可能满足手机的防尘要求，开口21的形状与摄像头组件100的外形尺寸高度吻合。本实施例中基座210的长度大于摄像头组件100的长度（在别的实施例中基座210的宽度可以大于摄像头组件100的宽度，或基座210的长度和宽度均大于摄像头组件100的长度和宽度），故开口21仅允许摄像头组件100伸出，而不允许基座210伸出（即基座210始终有一部分限位于开口21内侧），初始状态下摄像头组件100没有相对转动的角度。可将初始状态下摄像头组件100的转动角度定义为0°。
如图7所示，摄像头组件100受到驱动组件300的驱动向上升，升出手机20顶部，基座210受限于开口21内侧。
如图8所示，摄像头组件100受驱动组件300的驱动而转动时，脱离了初始状态。此时摄像头组件100无法被收回手机20内部。
如图9所示，摄像头组件100转动180度（即旋转），可实现后摄功能，而第一磁钢230和第二磁钢240的磁力，有助于驱动组件300转动摄像头组件100，使得摄像头组件100转动180度后，保持稳定的状态。摄像头组件100还可以再继续旋转至360度，但摄像头组件100要收回到手机20内仍然需要反转回位至0度的初始状态。
若拍摄完毕后，需要将摄像头组件100收回手机20内部，则需要将摄像头组件100精确复位至初始状态；故，驱动组件300驱动摄像头组件100旋转回到初始状态，在这过程中，若驱动组件300的驱动力不足，或者在驱动过程中出现驱动行程不足，可能导致摄像头组件100无法精确回复到初始状态。
而本实用新型的摄像模块10在初始状态下，第一磁钢230和第二磁钢240相互吸引，可增强摄像头组件100的初始状态的稳定性，有助于摄像头组件100准确旋转180度或360度，即使驱动组件300的驱动力无法精确将摄像头组件100旋转至初始状态，在第一磁钢230和第二磁钢240的磁力作用下，摄像头组件100可自动校准，回到初始状态位置，降低因旋转角度不够而无法收回至电子设备内部的风险。
本实用新型的驱动组件300和转动组件200的实现方式有很多种，在现有技术中可以找到许多实现的方案，本实用新型实施例在此提供优选的方案。
如图3和图6、图7所示，本实施例中的驱动组件300包括驱动电机310、丝杆320、导向杆330、驱动支架340和驱动滑块350；丝杆320和导向杆330平行并排固定安装在驱动支架340上；驱动滑块350穿设于丝杆320和导向杆330并与丝杆320螺纹传动连接同时与导向杆330滑动连接；驱动滑块350与传动组件200连接；丝杆320与驱动电机310连接并受驱动电机310驱动而转动以带动驱动滑块350沿着导向杆330的轴向线性运动从而驱动传动装置200运动。驱动电机通过一柔性电路板322与手机内部的控制电路（未图示）连接，从而可通过手机20控制摄像模块10的动作。驱动电机310转动时可带动丝杆320转动，由于丝杆320与驱动滑块350螺纹传动连接，故可带动驱动滑块350运动；驱动滑块350受到导向杆330的导向作用以及丝杆320的驱动作用，会沿着导向杆330的轴向做线性运动从而带动摄像头组件100升降。
本实用新型实施例的传动组件200还包括平行并排设置的第一传动杆250和第二传动杆260；第一传动杆250和第二传动杆260连接于所述基座210上与所述摄像头组件100相对的一侧，且第一传动杆250和第二传动杆260与驱动组件200连接并受驱动组件200驱动而沿轴向运动以驱动所述摄像头组件100进行升降运动。
具体应用中，第一传动杆250和第二传动杆260与丝杆320平行设置并与驱动滑块350连接（当驱动滑块350线性运动时会带动第一传动杆250和第二传动杆260运动）以受驱动组件200驱动而沿轴向运动以驱动所述摄像头组件100进行升降运动。
第一传动杆250和第二传动杆260分设于所述驱动支架两侧，使得摄像头组件100受到的驱动力均衡且稳定，不易晃动。
结合图2至图5所示，转轴220上设有第一齿轮221，第二传动杆260上设有与第一齿轮221啮合的第二齿轮261；第二传动杆260与驱动滑块350螺纹传动连接；第一传动杆250与基座210滑动连接，第一传动杆250上套设有弹簧251，弹簧251一端抵顶于基座210，另一端抵顶于驱动滑块350，第一传动杆250设有与驱动滑块350连接的限位部252，驱动滑块350连接于限位部252与弹簧251之间。限位部252和弹簧251可夹持驱动滑块350，使得驱动滑块向下运动时带动第一传动杆250向下运动同时防止驱动滑块350脱离第一传动杆250。弹簧251使得驱动滑块350向上向上运动且基座210不受阻挡时，可抵顶基座210向上运动，并在基座210的运动受到阻挡时被压缩储能。
当驱动组件300通过传动组件200驱动摄像头组件100伸出手机20后，基座210受到开口21的限制无法伸出，驱动电机310继续转动则驱动滑块350会压迫弹簧251和第二传动杆260，由于第二传动杆260与驱动滑块350螺纹传动连接，使得驱动滑块350的线性运动传递给第二传动杆260，转换为第二传动杆260的旋转运动，从而带动第二齿轮261转动，进而带动第一齿轮221转动，第一齿轮221则带动摄像头组件100旋转。当需要使摄像头组件100复位的时候，驱动电机310反转，带动驱动滑块350向下运动，由于弹簧251仍然处在压缩状态，当驱动滑块350向下运动时，弹簧的弹力释放，伸张第二传动杆260与驱动滑块350，使得第二传动杆反转（与之前转动的方向相反），从而带动摄像头组件100反转复位，回到初始状态，直到弹簧251的弹力被释放或弹力不足以使得第二传动杆260与驱动滑块350发生相对运动，则摄像头组件100开始向下运动。第一磁钢230和第二磁钢240在摄像头组件100回到初始状态时，起到了引导和定位的作用，可便于摄像头组件100复位并增强摄像头组件100的初始状态的稳定性，使得摄像头组件100下降时避免触碰到开口21的边缘而损伤或损坏。
本实施例仅通过一个驱动电机310即可实现摄像头组件100的升降和旋转。结构巧妙且成本低，在别的实施例中也可以用两个驱动电机分别控制摄像头组件100的升降和转动，本实用新型不做限制。
以上所述的仅是本实用新型的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本实用新型创造构思的前提下，还可以做出改进，但这些均属于本实用新型的保护范围。
