技术领域
本发明涉及摄像头模组技术领域，尤其涉及一种摄像头模组及其数码设备。
背景技术
目前绝大部分移动设备如手机、平板电脑，都会搭载摄像头模组，通过摄像头模组实现光信号与电信号之间的转换，记录和保存图像信息，从而实现拍照与摄影功能。与传统摄像***相比，手机摄像模组(Cell phone Camera Module，CCM)因其小型化、低功耗、低成本及高影像品质等优点而广泛地应用于各种新一代便携式摄像设备中。
目前，摄像模组的结构包括镜头单元、音圈马达(Voice Coil Motor，VCM)、红外线截止滤光片、图像传感器、软性电路板(Flexible Printed Circuit board，FPC)或印制电路板(Printed Circuit Board，PCB)，以及与手机主板连接的连接器。其中，音圈马达用于实现镜头单元的自动对焦功能，且音圈马达通常包括磁体、线圈等结构，摄像模组工作过程中，首先给线圈通电流，通电线圈在磁场中切割磁感线产生电磁力，线圈或者磁体在电磁力的作用下移动，从而带动与音圈马达连接的镜头单元移动，调整摄像模组的像距与物距，呈现清晰的图像。通常还可以在音圈马达中设置霍尔传感器(Hall-effect Sensor)，利用霍尔传感器测定音圈马达中磁场的变化，根据磁场的变化判断线圈或者磁铁的位置，从而实现音圈马达的闭环控制。最常 见的是手机摄像头中的自动对焦功能就是完全由整个驱动器来完成的。

具体实施方式
如背景技术所述，提供一种能够在摄像头模组工作时，在垂直光轴方向上有效限制摄像头模组的运动，提高摄像头模组的稳定性，是目前摄像头模组领域亟待解决的问题之一。
为了解决摄像头模组工作时的稳定性问题，本发明实施例提供一种摄像头模组。当所述移动单元沿着光轴方向带着镜头单元移动时，所述移动单元在垂直于光轴方向上的运动能够得到很好的限制，这样所述移动单元在垂直于光轴方向上的运动就很稳定，从而保证了摄像头模组在垂直于光轴方向上的运动的稳定性，保证摄像头的成像质量。
为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1为本发明一实施例中摄像头模组的结构示意图；图2为本发明一实施例中摄像头模组的***结构图；图3为本发明一实施例中底座的结构示意图；图4为本发明一实施例中载体与底座装配的结构示意图；图5为本发明一实施例中锁止结构的***结构图；图6为图1装配好之后的仰视图；图7为本发明一实施例中摄像头模组平行于光轴方向上的截面图；图8为本发明一实施例中第一弹性装置和第二弹性装置的放大图。
图7为了便于观察弹性装置与移动单元之间的关系，省略摄像头模组上的部分部件。
请参考图1至图4，一种摄像头模组100，包括移动单元101，弹性装置102。
所述移动单元101，带动镜头单元沿着光轴方向运动；
所述弹性装置102，均匀分布于所述移动单元101的周围，与所述移动单元101接触而产生弹性形变，以对所述移动单元101施加挤压力，所述挤压力的合力方向指向光轴且与光轴垂直；所述弹性装置102包括第一弹性装置103和第二弹性装置104，所述第一弹性装置103对所述移动单元101的挤压力的合力与所述第二弹性装置104对所述移动单元101的挤压力的合力方向相反。
在本实施例中，由于所述弹性装置102均匀的分布在所述移动单元101的周围，在所述弹性装置102与所述移动单元101接触而产生弹性形变时，所述弹性装置102给所述移动单元101施加挤压力，这种挤压力的合力方向指向光轴且与光轴垂直，同时由于挤压力来自于第一弹性装置103和第二弹性装置104，其中所述第一弹性装置103对所述移动单元101的挤压力的合力与所述第二弹性装置104对所述移动单元101的挤压力的合力方向相反，从而能够保证当所述移动单元101沿着光轴方向运动时，在垂直于光轴方向上由于挤压力的存在，限制了所述移动单元101在垂直于光轴方向上产生移动，从而提高了所述移动单元101在垂直于光轴方向上运动的稳定性，使得最终 摄像头模组100的成像质量得到提高。
请继续参考图1，还包括底座105。
在本实施例中，所述底座105上具有四周均匀分布的支撑组件，所述支撑组件包括第一支撑组件106和第二支撑组件107，所述第一弹性装置103安装于所述第一支撑组件106内，所述第二弹性装置104安装于所述第二支撑组件107内。
在本实施例中，所述底座105用于承载所述移动单元101，所述移动单元101相对于所述底座105沿着光轴方向运动。
在本实施例中，所述第一支撑组件106上具有第一卡位108和第二卡位109，所述第一弹性装置103包括卡接在所述第一卡位108上的第一金属片110和卡接在所述第二卡位109上的第一滚动件111，所述第一滚动件111的一侧固定在所述第一金属片110上，所述第一滚动件111的另一侧穿过所述第二卡位109后与所述移动单元101的线圈组件接触，当所述移动单元101移动时，所述移动单元101的线圈组件通过所述第一滚动件111、所述第一金属片110与对焦控制芯片形成电连接。
在本实施例中，所述第二支撑组件107上具有第三卡位112和第四卡位113，所述第二弹性装置104包括卡接在所述第三卡位112上的第二金属片114和卡接在所述第四卡位113上的第二滚动件115，所述第二滚动件115的一侧固定在所述第二金属片114上，所述第二滚动件115的另一侧穿过所述第四卡位113后与所述移动单元101的线圈组件接触，当所述移动单元101移动时，所述移动单元101的线圈组件通过所述第二滚动件115、所述第二金属片114与对焦控制芯片形成电连接。
在本实施例中，所述线圈组件上还设置有导轨，所述导轨适于分别与所述第一滚动件111和第二滚动件115电性接触，并在线圈组件一侧提供给所述第一滚动件111和第二滚动件115滚动行程。
在本实施例中，所述第一金属片110和所述第二金属片114采用直片型，这样便于所述第一金属片垂直***所述第一卡位108、所述第二金属片垂直***所述第三卡位112，从而便于装备，简化安装流程，提高效率。
在本实施例中，由于所述第一弹性装置103位于所述第一支撑组件106上，第二弹性装置104位于第二支撑组件107上，由于所述第一支撑组件106和所述第二支撑组件107均匀地分布在所述移动单元101的四周，在垂直于光轴方向上所述移动单元101在四周方向上都均匀地受到挤压力的作用，这样使得所述移动单元101的抗扭能力增强，从而增强所述移动单元101在垂直于光轴方向上运动的稳定性。
在本实施例中，所述第一金属片110上还具有弹性结构116，所述弹性结构116和所述第一滚动件111分别位于所述第一金属片110的相对两个表面上。

在其他实施例中，所述第二滚动件115还可为金属柱或者并排的三个金属球、四个金属球等，根据实际的需要设定即可。
在本实施例中，所述第二滚动件115采用两个并排的金属球的目的在于增加所述第二滚动件115与所述线圈组件之间的接触面积，一方面可以增加所述第二滚动件115与所述线圈组件之间的导电能力，另外一方面由于所述第二滚动件115与所述线圈组件之间的接触面积增大，增强了所述镜头单元在垂直于光轴方向上的扭转难度，从而减少了所述镜头单元在垂直于光轴方向上的扭转角度，提高所述镜头单元在垂直于光轴方向上的稳定性。
在本实施例中，所述底座105内还具有导线埋层(图中未示出)，所述导线埋层嵌入到所述底座105内部，所述导线埋层的一端与所述第一金属片110和所述第二金属片114连接，所述导线埋层的另一端通过PCB电路与对焦控制芯片相连接。
