其中，所述主体部222还设有弧形凹槽2222，所述弧形凹槽2222连通所述螺旋凹槽2221的朝向所述第一转动部223的一端。所述弧形凹槽2222与所述螺旋凹槽2221相连续。所述弧形凹槽2222垂直于所述滑动座3的滑动方向。当所述滑动块311自所述螺旋凹槽2221滑入所述弧形凹槽2222后，所述主体部222带动所述弧形凹槽2222转动时，所述滑动块311不会发生滑动，所述滑动块311停留在原位。换言之，所述弧形凹槽2222为空转区域。此时，与所述主体部222一起转动的所述第一转动部223则带动所述第二转动部32转动，使得所述滑动座3在原位置发生翻转。
其中，所述底座1包括限位部11。所述限位部11收容在所述收容腔10内。所述限位部11具有滑槽111。所述滑动部31还包括限位块312，所述限位块312滑动地收容于所述滑槽111。所述滑槽111的延伸方向与所述滑动座3的滑动方向一致。在所述滑动块311和所述限位块312的限制下，所述滑动部31能够平稳地滑动，从而使得所述滑动座3的滑动平稳。
其中，所述滑动部31还包括套环313。所述滑动块311和所述限位块312相对地固定在所述套环313的外侧面上。所述套环313套设在所述连接杆35外侧。所述套环313与所述连接杆35外侧之间间隙连接，所述套环313能够相对所述连接杆35转动，使得所述滑动部31能够相对所述连接杆35转动。此时，所述丝杠22和所述限位部11分别位于所述连接杆35的相对两侧。所述连接杆35的外侧设有环形凹槽352，所述套环313嵌设在所述环形凹槽352中，从而在所述滑动座3的滑动方向上得到限位。
在另一种实施方式中，请参阅图12，所述驱动组件2还包括套设在所述丝杠22外侧的驱动块25。所述驱动块25与所述丝杠22螺接。所述丝杠22转动时，带动所述驱动块25移动。所述驱动块25与所述滑动部31之间产生磁吸力。所述驱动块25移动时，带动所述滑动部31移动。
由于所述驱动块25与所述滑动座3的所述滑动部31之间通过磁吸力彼此连接，因此所述驱动块25与所述滑动座3之间无刚性连接，若所述摄像头模组301受到朝向所述底座1冲击的冲击力，所述滑动座3会快速克服磁吸力脱离所述驱动块25，从而使得滑动座3携带所述摄像头模组301收进所述收容腔10，能够避免所述摄像头模组301因受到刚性冲 击而损毁，使得应用所述摄像头组件200的所述移动终端100的可靠性较高。
具体而言，所述丝杠22的外表面设有螺旋状滑槽。所述驱动块25设有通孔342，通孔342的孔壁上设卡块。所述驱动块25套设在所述丝杠22的外侧面上，所述卡块收容于所述螺旋状滑槽，以沿所述螺旋状滑槽移动。在其他实施方式中，所述丝杠22的外表面可设外螺纹，所述通孔的孔壁上可设内螺纹，内螺纹与外螺纹螺接。
其中，所述驱动块25和所述滑动部31均采用永磁材料，所述驱动块25的磁性与所述滑动部31的磁性相反。磁性相反的所述驱动块25与所述驱动块25之间产生磁吸力，两者彼此吸引，从而能够通过移动所述驱动块25带动所述驱动块25和滑动座3移动。永磁材料又称“硬磁材料”，指的是一经磁化即能保持恒定磁性的材料。永磁材料包括但不限于铝镍钴系永磁合金、铁铬钴系永磁合金、永磁铁氧体、稀土永磁材料及复合永磁材料等。
其中，所述驱动块25采用永磁材料，所述滑动部31采用铁磁性材料。铁磁性材料包括但不限于铁，钴，镍和钆。所述连接杆35采用非铁磁性材料。此时，所述驱动块25与所述滑动部31之间产生磁吸力，所述驱动块25吸引所述滑动部31，从而能够通过移动所述驱动块25带动所述滑动部31和滑动座3移动。所述连接杆35采用非铁磁性材料，不被所述驱动块25吸引，从而避免对所述驱动块25与所述滑动部31之间的磁吸力产生干扰，使得所述驱动块25能够准确控制所述滑动部31的移动。
其中，所述驱动块25与所述滑动部31之间形成间隙。在所述摄像头模组301受到朝向所述底座1冲击的冲击力时，所述间隙能够避免所述驱动块25撞击所述滑动部31，并使得所述滑动座3更快速地克服磁吸力脱离所述驱动块25，从而使得滑动座3携带所述摄像头模组301收进所述收容腔10，能够避免所述摄像头模组301因受到刚性冲击而损毁，使得所述摄像头组件200和所述移动终端100的可靠性较高。进一步地，所述间隙小于等于1mm。此时，所述驱动块25与所述滑动部31之间的磁吸力，能够保证所述驱动块25顺利通过所述滑动部31移动所述滑动座3。
可选的，请一并参阅图3和图5，所述连接杆35具有贯穿孔351。所述贯穿孔351沿所述连接杆35的轴向延伸。所述基座33内形成器件空间330。所述贯穿孔351连通所述器件空间330。所述摄像头组件200还包括电路板201和电连接所述电路板201的连接线缆202。所述电路板201收容于所述器件空间330。所述摄像头模组301电连接所述电路板201。所述连接线缆202通过所述贯穿孔351伸入所述收容腔10，以电连接位于所述收容腔10内的其他器件(例如所述主板500)。

其中，所述第一摩擦面2231为圆台侧面。所述第一摩擦面2231展开后形成环状扇形。所述第二摩擦面321为圆台侧面。所述第二摩擦面321展开后形成环状扇形。所述第一摩擦面2231的倾斜方向与所述第二摩擦面321的倾斜方向相反。例如，所述第一摩擦面2231朝向所述主体部222倾斜。所述第二摩擦面321朝向所述基座33倾斜，使得所述第二摩擦面321能够在所述第二转动部32向所述第一转动部223移动的过程中接触所述第一摩擦面2231。其中，所述第二摩擦面321与所述第一摩擦面2231相切，以使所述第二摩擦面321与所述第一摩擦面2231的接触面积更大。所述第二摩擦面321接触所述第一摩擦面2231时，两者之间形成过盈配合，以避免在所述第一转动部223带动所述第二转动部32转动的过程中，所述第二摩擦面321脱离所述第一摩擦面2231。
在另一种实施方式中，请参阅图13，所述第一转动部223具有第一齿部2232。所述第二转动部32具有第二齿部322。所述第二转动部32与所述第一转动部223配合时，所述第二齿部322啮合所述第一齿部2232。所述第一齿部2232转动时，带动所述第二齿部322转动。

在本实施方式中，所述滑动座3经所述伸缩口131滑动连接所述边框13，以使所述摄像头模组301经所述伸缩口131伸出所述收容腔10或收进所述收容腔10。所述底板12可为所述移动终端100的后盖。所述边框13可为所述移动终端100的周边框13。当然，在其他实施方式中，所述底板12也可以为所述移动终端100的中隔板。
其中，所述底座1的底板12对所述滑动座3和所述驱动组件2进行承载，以保证所述驱动组件2可以驱动所述滑动座3相对所述底座1伸缩。所述马达21固定在所述底板12上。所述丝杠22的延伸方向大致垂直于所述边框13设有所述伸缩口131的一侧，以减小 所述驱动块25的移动行程。所述边框13对所述滑动座3和所述驱动组件2遮盖隐藏，以提高所述移动终端100的外观性能和安全性能。由于所述伸缩口131设置在所述边框13上，因此所述摄像头模组301在所述底座1的侧边伸缩，也即所述摄像头模组301在所述移动终端100的侧面伸缩，所述摄像头模组301不占据所述移动终端100的正面空间。
其中，所述滑动座3的基座33的外周侧壁与所述伸缩口131的内周侧壁间隙配合。此时，所述基座33的外周侧壁与所述伸缩口131的内周侧壁之间的间隙能够保证所述滑动座3可以相对所述底座1顺利滑动。
其中，所述基座33远离所述滑动部31的侧部外周卡设有密封圈(图中未示出)，所述密封圈在所述摄像头模组301收进所述收容腔10时，密封在所述基座33的外周侧壁与所述伸缩口131的内周侧壁之间。所述密封圈在所述摄像头模组301收进所述收容腔10时，密封在所述基座33的外周侧壁与所述伸缩口131的内周侧壁之间。所述密封圈用以防止外界水汽和粉尘经所述伸缩口131进入所述收容腔10，从而提高所述摄像头模组301和所述移动终端100的可靠性。
