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。与传统摄像系统相比，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。
随着智能手机行业的快速发展，人们对手机摄像头成像效果的要求也在逐步提高。焦距变焦范围是一个影响手机摄像头成像效果的重要因素。这些需要音圈马达能够进行大行程驱动，而大行程驱动需要在行程范围内保持摄像头稳定，这对音圈马达的稳定性提出了较高的要求。

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同时能够保证使得摄像头模组具有较大的行程，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。由于所述第一滚动件的凸出表面于所述载体侧壁的表 面，所述第一滚动件的凸出表面与所述金属导轨接触，这样在所述移动单元移动时，所述第一滚动件随所述移动单元移动，且与所述固定单元形成移动滑动接触，这样形成的所述摄像头模组能够具有较大的行程，从而能够获得更好的成像效果。
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爆炸结构图；图2为本发明一实施例中底座的结构示意图；图3为本发明一实施例中底座与载体安装的爆炸图；图4为本发明一实施中载体与线圈的安装图；图5为本发明一实施例中锁止结构的爆炸结构图；图6为本发明一实施例中锁止结构与底座、载体、以及磁石装配的结构示意图；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7为了便于锁止结构与移动单元之间的关系，省略摄像头模组上的部分部件。

所述移动单元101包括载体103及设于所述载体103侧壁的第一滚动件104，所述第一滚动件104具有凸出于所述载体103侧壁的表面；
所述固定单元102包括底座106，所述底座106上具有第一支撑件107，所述第一支撑件107内具有沿光轴方向延伸的金属导轨105。
所述载体103安装于所述底座106时，所述第一滚动件104的凸出表面与所述金属导轨105接触，用于在所述移动单元101移动时，所述第一滚动件104随所述移动单元101移动，且与所述第一支撑件107形成滚动或滑动接触。
在本实施例中，由于所述移动单元101移动时，所述第一滚动件104在所述金属导轨105上滚动或者滑动，所述第一滚动件104设置 于在所述载体103的侧壁上，这样在所述移动单元101移动时，所述第一滚动件104随所述移动单元101移动的过程实质上也是所述移动单元101随着所述第一滚动件104移动的过程，所以所述第一滚动件104在所述金属导轨105上移动的距离等效于所述摄像头模组100的行程，所以由于所述第一滚动件104在所述金属导轨105上能够移动较大的距离，这样对应的所述摄像头模组100就具有较大的行程，从而保证了形成的摄像头模组100具有较好的成像质量。
在本实施例中，所述第一滚动件104为导电滚珠，采用导电滚珠的原因一方面起到导电的作用，另外一方面所述导电滚珠能够在所述金属导轨105内滚动，从而减少所述移动单元101移动时产生的摩擦力，提高摄像头模组的成像质量。
在本实施例中，所述第一滚动件104与所述载体103侧壁之间可拆卸连接；在其他实施例中，所述第一滚动件104与所述载体103侧壁之间还可固定连接。

在本实施例中，请参考图4，所述线圈组件109位于朝向所述底座106侧的所述载体103的表面上，即采用底部装入所述线圈组件109的设计有助于降低所述载体103所需高度，使得同等行程下音圈马达肩高最小。,在本实施例中，由于所述弹片108的存在，一方面在所述移动单元101移动时与所述线圈组件109形成电连接；另外一方面所述弹片108与所述线圈组件109之间形成弹性形变，施加反弹力给所述第一滚动件104，其中所述反弹力是垂直于光轴方向并指向光轴，这样能够限制所述移动单元101在垂直于光轴方向上的移动，从而提高所述移动单元101在光轴方向上的运动稳定性。
请继续参考图1至图3，所述底座106上还具有第二支撑件110。

在本实施例中，所述第一滚动件104和所述第二滚动件112相互配合，在所述移动单元101移动时，所述移动单元101能够具有较大的移动距离，从而保证摄像头模组具有较大的行程，以提高摄像头模组的成像质量。
在本实施例中，所述第二滚动件112部分嵌入所述限位槽111，以使所述移动单元101沿光轴方向稳定移动。
在本实施例中，所述限位槽111采用的是“V”型槽结构，这样所述第二滚动件112部分嵌入所述限位槽111内时，所述第二滚动件112与所述限位槽111之间的接触是两点接触，这样一方面减少所述第二滚动件112与所述限位槽111之间的运动摩擦力，有助于所述第二滚动件112的滚动；另外一方面所述第二滚动件112与所述限位槽111、所述载体103之间是三点接触，保证在所述移动单元101移动时，所述第二滚动件112既可以跟着所述移动单元101移动又可以在所述限位槽111内转动，从而实现所述第二滚动件112与所述第二支撑件110之间滚动接触或者滑动接触。
在本实施例中，所述底座106还包括电路板143，其上设有驱动芯片，霍尔传感器、印刷电路板等。
