Description

用于摄像模组的驱动装置、摄像模组及终端设备 技术领域
本申请属于摄像模组领域，具体地涉及一种用于摄像模组的驱动装置、摄像模组及终端设备。
背景技术
在手机等电子终端中，摄像模组成为了必不可少的一部分。为满足摄像的高清晰度需求，要求摄像模组能自动对焦，通过驱动机构带动镜头进行纵向运动来实现自动对焦。
一方面，由于手机的轻薄化发展需求，这使得摄像模组的安装空间减小减薄。传统的VCM马达驱动包括磁石、线圈等，虽然能够驱动镜头组件到达目标位置以实现自动对焦的功能，但是结构复杂，并且会增大摄像模组的结构，使模组结构的整体尺寸难以降低、摄像模组整体的小型化难以实现。另一方面，为满足多样化以及高清晰度的摄像需求，大光圈、大像面等被引入摄像模组中，镜头中镜片数量不断增加、镜头质量增加。传统的VCM马达驱动存在驱动力不足的倾向，并且在常规方法中也存在电力消耗较大等问题。SMA(形状记忆合金)材料由于其加热收缩的特性，被设置为另一种可行的致动器，用以代替现有的VCM驱动器。相对于VCM驱动器，SMA驱动器能够满足小型化的要求。
另外，在实际拍照摄像过程中，微小的抖动将导致图像虚化、不清晰，尤其是手机终端在手持条件下的拍摄，这种因手抖引起的图像不清晰更为常见。因此光学图像稳定系统(OIS)被引入到各类高端手机终端中，以解决有手抖引起的像糊问题。OIS防抖的原理为，通过位置检测装置，比如陀螺仪等检测抖动产生的位置偏移量，在依据这个偏移量计算出需要补正的位移并驱动光学防抖致动器驱动相应的方向和偏移量，达到指定位置，从而补偿相应的位置和角度，从而克服因抖动引起的像糊问题。
现有的光学防抖装置由垂直于光轴的平面移动抖动防抖线圈以及防抖磁石组成以及悬线结构组成。例如，光学防抖装置可以包括透镜部、用于自动聚焦用及抖动修正的透镜驱动装置，以及摄像部。透镜驱动装置具备OIS可动部、OIS固定部以及支撑部件，OIS可动部通过支撑部件与OIS固定部连接，支撑部件由4根悬线构成，悬线的一端固定于OIS的可动部，另一端固定于OIS固定部。OIS可动部在XY平面内可摆动地被悬线支撑。

以下将结合附图，对本申请的技术方案进行详细说明。

根据本申请的第一方面，提供一种用于摄像模组的驱动装置1000，如图2、图7所示。驱动装置1000包括：第一驱动装置1100、第二驱动装置1200和一组弹性支撑部件1300。根据本申请的一些实施例，第一驱动装置1100可以为SMA驱动装置，用于驱动镜头组件沿着光轴方向上下运动；第二驱动装置1200可以为OIS驱动装置， 用于驱动镜头组件在垂直于光轴的平面内水平运动。一组弹性支撑部件1300连接第一驱动装置1100和第二驱动装置1200，在摄像模组的光轴方向上悬空支撑第一驱动装置1100。
下面将结合具体实施例，对本申请提供的驱动装置进行详细描述。
图2示出根据本申请第一示例实施例的驱动装置结构图；图3示出根据本申请第一示例实施例的驱动装置爆炸图；图4示出根据本申请第一示例实施例的一组弹性支撑部件结构示意图。
根据本申请的第一实施例，参见图2和图3，SMA驱动装置1100包括镜头载体1110，第一弹片1120、向上SMA驱动器1130、向下SMA驱动器1140、第二弹片1150和基座1160。OIS驱动装置1200包括基板1210，一组线圈1220和一组磁性体(图3中未示)。一组弹性支撑部件1300，设置于所述基板1210上。根据本申请的示例实施例，一组弹性支撑部件1300可以是四个弹性支撑部件，设置于所述基板1210的四个角落。
如图3和4所示，弹性支撑部件1300包括第一水平端1310、第二水平端1320、和竖直弯折端1330。第一水平端1310固定在所述基板1210上。竖直弯折端1330一端与所述第一水平端1310相连，另一端与所述第二水平端1320相连。第二水平端1320在摄像模组的光轴方向上悬空支撑所述基座1160。根据本申请的一些实施例，第一水平端1310可以与第二水平端1320在结构上存在高度差，例如所述第二水平端1320在所述摄像模组的光轴方向上高于所述第一水平端1310。根据本申请的另一些实施例，也可以将第一水平端1310通过高度调整块1400与所述基板1210相连，固定在所述基板1210上。
第二水平端1320在摄像模组的光轴方向上高于所述第一水平端1310并与所述SMA驱动装置的基座1160相连，可以为SMA驱动装置提供悬空的弹性支撑。第一水平端1310被高度调整块1400垫高，也可以使得第二水平端1320的下表面与OIS驱动装置1200的基板1210存在间隙，使其悬空，为SMA驱动装置的上下运动提供了空间。第二水平端1320的上表面与SMA驱动装置1100的基座1160底部接触，从而提供弹性支撑。根据本申请的另一些实施例，所述基座1160底部包括一组凸起1161，与所述第二水平端1320对应设置，所述第二水平端1320通过所述凸起1161悬空支撑所述基座。通过在基座1160的底部设置凸起1161，可以保证第一水平端1310与基座1160之间的间隙，尤其是在设置高度调整块的情况下。

参见图3，本申请的示例实施例中，U型弹性臂的数量是两个，其数量可以根据需要进行设置，本申请对此不作限制。竖直弯折端1330通过多次弯折连接，增加了支撑部件的变形强度，从而可以提高可靠性，既允许基座1160整体相对于基板1210在平面上运动又不易使弹性支撑部件1300扭转弯折，而导致基座整体翻转。
根据本申请的示例实施例，高度调整块1400与基板1210、第一水平端1310与高度调整块1400的连接方式可以是粘接、焊接或者机械连接中一种，本申请不限于此。

所述载体主体1111进一步包括载体环1114和载体支架1115，其中所述载体支架1115被一体地设置于所述载体环1114的外周。所述第一驱动器1130和所述第二驱动器1140通过所述载体支架1115提供对所述载体环1114的向上和向下的作用力，从而驱动镜头载体1110向上或向下地运动。
所述载体主体1111进一步包括第一弯曲块1116和第二弯曲块1117，设置于所述载体支架1115的四周，用于分别与所述第一驱动器1130、第二驱动器1140配合，驱动所述镜头载体1110上下运动。
镜头载体1110还包括第一限位装置1118，用于限制所述镜头载体1110被驱动而向上移动的最大距离。所述限位装置1118自所述载体支架1115的上表面向上地延伸而成，可以与所述载体支架1115为一体式结构。
镜头载体1110还包括间隔装置1119，设置于所述载体支架1115的四周，用于间隔所述镜头载体1110与摄像模组壳体的内壁。所述间隔装置1119被一体地设置于所述镜头载体1110，可以从载体支架1115的侧边一体地向外延伸而成，并向外地凸出于所述第一驱动器1130和所述第二驱动器1140的位置，从而限制所述第一驱动器1130和所述第二驱动器1140的SMA线接触到摄像模组的壳体。
第一驱动器1130包括第一SMA驱动线1131和第一固定装置1132，其中所述第一SMA驱动线1131的两端被设置于所述第一固定装置1132上，通过所述第一固定装置1132将第一驱动器1130固定于基座1160上。所述第一驱动器1130的第一SMA驱动线1131设置于所述第一弯曲块1116的下方，其中所述第一驱动器1130的第一SMA驱动线1131以热驱动的方式收缩而拉升，从而推动所述第一弯曲块1116向上地移动。
第二驱动器1140包括第二SMA驱动线1141和第二固定装置1142，其中所述第二SMA驱动线1141的两端设置于所述第二固定装置1142上，通过所述第二固定装置1142将第二驱动器1140固定于基座1160上。所述第二驱动器1140的第二SMA驱动线1141被设置于第二弯曲块1117的下方，其中所述第二SMA驱动线1141以热驱动的方式收缩，而牵引所述第二弯曲块1117向下地移动。
需要说明的是，所述SMA线通过自身加热或受热源加热的方式实现所述热驱动。也就是说，所述SMA线可通过自身发热或者被其他热源加热的方式受热，而收缩所述SMA线的长度，从而驱动可移动部件的运动。优选地，在本申请第一较佳实施例中，所述SMA线的热驱动方式为自身电加热的方式实现热驱动，并且通过控制所述SMA线电流的大小控制所述SMA线驱动作用力的大小。简言之，当所述SMA线电流增大的时候，所述SMA线被电加热的温度升高，所述SMA线热收缩，从而所述SMA线的驱动作用力增大；当所述SMA线电流减小的时候，所述SMA线被电加热的温度降低或者在环境温度下所述SMA线的温度降低，所述SMA线放松，从而所述SMA线的驱动作用力减小。
根据本申请的示例实施例，所述第一固定装置1132的高度大于所述第二固定装置1142的高度。其中所述第一固定装置1132支撑所述第一SMA驱动线1131的两端，以使第一SMA驱动线1131绕过所述第一弯曲块1116，而形成“V”字型的牵引结构。相应地，所述第一固定装置1142支撑所述第二SMA驱动线1141的两端，以使所述第一SMA驱动线1141绕过所述第二弯曲块1117，而形成倒置的“V”字型的牵引结构。由此，所述SMA驱动装置1100的所述第一驱动器1130和所述第二驱动器1140为所述镜头载体1110提供互为反向的作用力，通过驱动所述镜头载体1110带动镜头组件向上和向下地移动。
所述第一弹片1120设置于所述镜头载体1110的上方，所述第二弹片1150设置于所述镜头载体1110的下方，支撑所述镜头载体1110。在静止未通电的状态，所述上第一弹片1120和所述第二弹片1150共同支撑所述镜头载体1110，通过所述镜头载体1110将镜头维持在中置位置。当所述镜头载体1110在被所述SMA驱动设备1100向上或向下驱动时，所述第一弹片1120和所述第二弹片1150均衡所述镜头载体1110各个方向受到的支撑作用力，以使得所述镜头载体1110的各个方向受到的驱动作用力相同，从而通过所述镜头载体1110维持镜头组件在驱动过程中移动的平稳性。
所述第一弹片1120包括第一弹片环1121和自所述第一弹片环1121向外延伸而成的第一延伸部1222。其中，所述第一弹片环1121设置于所述镜头载体1110的所述载体环1114，其大小适配于所述载体环1114。根据本申请的一些实施例，所述第一弹片1120为具有镂空结构的薄片状弹性体，能承受一定的作用力，并且在弹性作用下回复至原形。所述第一弹片1120可以通过机械冲压或蚀刻成形的方式制成。
在初始状态下，所述第一弹片1120处于自然伸展状态，其中所述第一弹片环1121和第一延伸部1222处于同一水平面。当所述第一弹片环1121被所述镜头载体1110驱动地向上移动，所述第一弹片环1121和所述第一延伸部1222的中间连接部分发生弹性变形。所述第一延伸部1222向所述镜头载体1110提供向下的弹性作用力。
所述第二弹片1150进一步包括第二弹片环1151和自所述第二弹片环1151向外延伸而成的第二支撑端1152。其中所述第二弹片1150设置于所述基座1160上。所述第二弹片环1151设置于所述镜头载体1110的载体环1114的下方，其大小适配于所述载体环1114，通过所述第二弹片环1151对所述镜头载体1110提供向上的支撑力作用。根据本申请的示例实施例所述第二弹片1150为具有镂空结构的薄片状弹性体，可以通过机械冲压或蚀刻成形的方式制成。根据本申请的示例实施例，所述第一弹片1120和所述第二弹片1150可以为金属材质的弹性装置。
在初始状态下，所述第二弹片环1151在所述基座1160的支撑作用下，向上支撑所述镜头载体1110，通过所述镜头载体1110将镜头组件位置在中置的位置。当所述SMA驱动设备1100的所述第二驱动器1140驱动所述镜头载体1110向下的移动时，所述镜头载体1110向下地挤压所述第二弹片环1151，使得所述第二弹片环1151的所述第二支撑端1152发生弹性形变。所第二支撑端1152支撑所述镜头载体1110各个部位在水平方向的受力平衡。所述第二弹片环1151通过所述第二弹片环1151向所述镜头载体1110提供向上的弹性作用力，以支撑所述镜头载体1110向上移动，由下部回复至中置位置。
所述基座1160包括基座主体1161、凸台1162和第二限位装置1163。其中所述凸台1162被设置于所述基座主体1161的边角，用于摄像模组壳体和所述基座1160之间的定位安装。可以理解的是，所述凸台1162向上地凸出于所述基座主体1161所在平面。所述第二限位装置1163可以自所述基座主体1161的上表面一体地向上延伸而成。所述第二限位装置1163与所述镜头载体1110的距离为镜头组件向下运动的极限距离。当所述镜头载体1110被所述第二驱动器1140向下驱动地移动时，所述镜头载体1110被向下移动接触至所述第二限位装置1163的距离为所述镜头载体1110向下的最大机械行程。

OIS驱动装置1200位于SMA驱动装置1100下方。如图8所示，OIS驱动装置1200包括基板1210，一组线圈1220、一组磁性体1230和第二固定支撑部件1240。一组磁性体1230与SMA驱动装置的基座1610相连。一组线圈1220设置于基板1210上，与一组磁性体1230相对设置。OIS驱动装置1200还包括位置感测元件(图中未示)，设置于所述基板1210上，与所述一组线圈1220相邻。通过位置感测元件可以感测摄像模组的镜头组件所处的位置。根据感测元件获得的位置信息，可以通过所述一组线圈1220与所述一组磁性体1230之间的磁性力，驱动所述SMA驱动装置并带动镜头组件在垂直于摄像模组光轴方向水平移动，从而实现抖动校正。
一组弹性支撑部件1300用于连接第一驱动装置1100、第二驱动装置1200。如图8和9所示，一组弹性支撑部件1300可以是一组弹片1320。一组弹片1320设置于所述弹性支撑主体1310的外围。弹片1320包括第一水平端1321、第二水平端1322、和竖直弯折端1324。第一水平端1321与所述弹性支撑主体1310相连，从所述弹性支撑主体1310向外延伸。竖直弯折端1324一端与所述第一水平端1321相连，另一端与所述第二水平端1322相连。根据本申请的示例实施例，一组弹片1320可以是四个弹片，设置于所述弹性支撑主体1310外围的四个角落。如图8所示，弹性支撑部件1300的第一水平端1321与第一驱动装置1100的弹性支撑主体1310固定相连，第二水平端1322与第二驱动装置1200固定相连。根据本申请的一些实施例，弹性支撑主体1310在所述摄像模组的光轴方向上高于所述第二水平端1322，从而将所述第一驱动装置1100在所述摄像模组的光轴方向上悬空支撑。
如图9所示，根据本申请的示例实施例，弹性支撑部件1300可以是金属弹簧片，例如板簧。根据本申请的另一些示例实施例，竖直弯折端1324可以包括第一弹性臂和第二弹性臂。第一弹性臂与所述第二弹性臂斜向交叉相连，即第一弹性臂与第二弹性臂处于不同的平面。例如，通过L型水平连接部1323相连，则第一弹性臂与第二弹性臂所在的平面相互垂直。所述第一弹性臂或第二弹性臂可以包括至少一个U型弹性臂。
参见图9，本申请的示例实施例中，U型弹性臂的数量是两个，其数量可以根据需要进行设置，本申请对此不作限制。竖直弯折端1324通过多次弯折连接，增加了支撑部件的变形强度，从而可以提高可靠性，既允许第一驱动装置1100整体相对于第二驱动装置1200在平面上运动又不易使弹性支撑部件1300扭转弯折，而影响支撑稳定性。

通过弹性支撑部件1300将SMA驱动装置1100和OIS驱动装置1200悬空弹性支撑，既能够允许SMA驱动装置1100相对于OIS驱动装置1200在一定范围内沿光轴方向上下运动，实现自动对焦；又允许SMA驱动装置1100相对于OIS驱动装置1200在垂直于光轴的方向做水平移动，实现抖动校正。而且，相对于悬线结构，弹性支撑部件1300的结构更加稳定而且装配工艺简单，从而可以在保证功能的同时降低生产成本。

初始状态下，驱动装置1000将所述镜头组件2100保持于中置位置，其中所述镜头组件2100被沿着光轴方向与所述感光元件2400保持一定的距离。当需要调整所述镜头组件2100的成像位置进行对焦时，驱动装置1000驱动所述镜头组件2100沿光轴方向上下地移动，以调整所述镜头组件2100与所述感光元件2400之间的距离。当需要进行抖动调整时，驱动装置1000驱动所述镜头组件2100在垂直于光轴方向的平面上下水平移动。
