下面结合附图，对本申请的一些实施方式作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
请参阅图1，本申请实施例提供一种光学防抖驱动器100，用于控制光学组件300进行旋转，以对镜头的转动进行补偿，具体地，当镜头由于外界因素顺 时针转动一定角度时，光学防抖驱动器100可控制光学组件300逆时针转动相应角度，例如，拍摄过程中，镜头顺时针转动45度，光学防抖驱动器100控制光学组件300逆时针转动45度，以实现镜头的旋转进行补偿，保证成像质量。光学防抖驱动器100包括基板10、移动件20及驱动件30。
请参见图2，基板10可以为椭圆形或多边形，其中多边形包括三角形、四边形、五边形、六边形等，但不限于此，具体到本实施例中，基板10为四边形。基板10具有第一安装面11，第一安装面11为平面，第一安装面11连接有光学组件300。移动件20大致为矩形板状，可以理解地，移动件20也可为圆形、方形、多边形、异形等。但不限于此。移动件20连接于基板10的一侧。驱动件30与移动件20连接，用于驱动移动件20沿直线运动并带动基板10转动。
请一并参见图3，基板10的靠近移动件20的位置设有凸伸结构12，凸伸结构12为块状结构。可以理解地，凸伸结构211也可为球形、圆柱状等，但不限于此。移动件20的靠近基板10的位置设有用于夹持凸伸结构12的夹持结构21，夹持结构21跟随移动件20沿直线运动时可带动凸伸结构12及基板10转动。可以理解地，在其他实施例中，凸伸结构12也可为棱锥状、棱台状等结构，但不限于此。
在本实施例中，基板10和凸伸结构12为一体结构，移动件20和夹持结构21为一体结构。
可以理解地，在其他的实施例中，基板10和凸伸结构12为一体结构，移动件20和夹持结构21为分体结构。
可以理解地，在其他的实施例中，基板10和凸伸结构12为分体结构，移动件20和夹持结构21为一体结构。
可以理解地，在其他的实施例中，基板10和凸伸结构12为分体结构，移动件20和夹持结构21为分体结构。
如此，将凸伸结构12与基板10设置为分体结构，以及夹持结构21与移动件20设置为分体结构时，当其中一者损坏时，只需更换损坏的一者，维修成本较低；将凸伸结构12与基板10设置为一体结构，以及夹持结构21与移动件20设置为一体结构时，省略了凸伸结构12与基板10，以及夹持结构21与移动件 20的安装步骤，方便安装。
夹持结构21具有一定的弹性。夹持结构21包括相对设置的第一夹片211和第二夹片212，第一夹片211和第二夹片212之间存在间隙，凸伸结构12的一端凸伸至该间隙内，且分别抵接第一夹片211和第二夹片212，如此，由于夹持结构21具有弹性，也即，第一夹片211和第二夹片212均具有弹性，移动件20运动时，第一夹片211和第二夹片212夹持凸伸结构12的位置也会发生弹性形变，从而带动凸伸结构12及基板10在小范围内旋转，进而带动光学组件300转动，以对镜头的旋转进行补偿。
具体地，移动件20的底部设有容置槽22，容置槽22为截面大致呈矩形的槽。第一夹片211和第二夹片212相对设置在移动件20底部的容置槽22内，且第一夹片211和第二夹片212的一端分别连接容置槽22的相对的槽壁，另一端凸伸出移动件20的靠近基板10的侧边，凸伸结构12的一端凸伸第一夹片211和第二夹片212之间的间隙中。
在本实施例中，第一夹片211和第二夹片212均为弧形的弹簧片。
可以理解地，在其他的实施例中，第一夹片211和第二夹片212均为弹簧，其中一个弹簧的一端垂直连接容置槽22的槽壁，另一端朝另一弹簧延伸，两个弹簧之间存在间隙，凸伸结构12的一端凸伸至两个弹簧之间的间隙中，其中两个弹簧的相互靠近的一端抵持在凸伸结构12的相对两侧。
可以理解地，在其他的实施例中，夹持结构22为圆柱状的橡胶。橡胶的设置位置和连接关系与弹簧相同，在此不再赘述。
在本申请的另一实施例中，请参见图4，夹持结构21靠近凸伸结构12的位置设有收容槽213，收容槽213具有相对的第一夹持面2131和第二夹持面2132，第一夹持面2131和第二夹持面2132均为平面，第一夹持面2131和第二夹持面2132之间形成的间隙的形状与凸伸结构12的外形相适配，凸伸结构12的一端凸伸至收容槽213内，且分别抵接第一夹持面2131和第二夹持面2132。如此，由于夹持结构21具有弹性，凸伸结构12在移动时，第一夹持面2131和第二夹持面2132会发生形变从而使得夹持结构21发生弹性形变，进而夹持结构21带动基板10在小范围内旋转，带动光学组件300转动，以对镜头的旋转进行补偿。 具体地，夹持结构21为长条状的橡胶。
可以理解地，在其他的实施例中，移动件20的靠近基板10的位置设有凸伸结构12，基板10的靠近移动件20的位置设有用于夹持凸伸结构12的夹持结构21，凸伸结构12跟随移动件20沿直线运动时可带动夹持结构21及基板10转动。
需要说明的是，该实施例中的凸伸结构12的结构，以及夹持结构21的结构和数量跟上述实施例中的凸伸结构12的结构，以及夹持结构21的结构和数量相同，故该实施例中不再赘述。在该实施例中，凸伸结构12与移动件20为一体结构，夹持结构21与基板10为一体结构。可以理解地，在其他的实施例中，凸伸结构12与移动件20为一体结构，夹持结构21与基板10为分体结构。可以理解地，在其他的实施例中，凸伸结构12与移动件20为分体结构，夹持结构21与基板10为一体结构。可以理解地，在其他的实施例中，凸伸结构12与移动件20为分体结构，夹持结构21与基板10为分体结构。如此，将凸伸结构12与移动件20设置为分体结构，以及夹持结构21与基板10设置为分体结构，当其中一者损坏时，只需更换损坏的一者，维修成本较低；将凸伸结构12与移动件20设置为一体结构，以及夹持结构21与基板10设置为一体结构时，省略了凸伸结构12与基板10，以及夹持结构21与移动件20的安装步骤，方便安装。
光学防抖驱动器100还包括载体40。载体40大致为矩形板状。载体40设于基板10背离光学组件的一侧，驱动件30设于载体40上，基板10靠近载体40的一侧还具有与第一安装面11相对设置的第二安装面13，第二安装面13为平面，其中第二安装面13和第一安装面11为基板10的相对的表面。载体40的与第二安装面13相对的一侧具有第一装配面41，第一装配面41为平面。
在一些实施例中，第二安装面13具有一凸轴结构14，第一装配面41具有与凸轴结构14转动连接的轴孔结构42。具体到本实施例中，凸轴结构14和轴孔结构42均为圆环状结构，其中轴孔结构42可为盲孔结构，也可为通孔结构。
可以理解地，在其他的实施例中，第二安装面13具有轴孔结构42，第一装配面41具有与轴孔结构42转动连接的凸轴结构14。具体到该实施例中，凸轴 结构14和轴孔结构42均为圆环状结构，其中轴孔结构42可为盲孔结构，也可为通孔结构。
如此，凸轴结构14和轴孔结构42配合使用，保证了载体40的转动精度，提升了光学组件300的旋转防抖补偿的效果。
基板10还具有形成于第一安装面11和第二安装面13之间的基板外侧面15，光学防抖驱动器100还包括限位部50，限位部50位块状结构，可以理解地，在其他的实施例中，限位部50位圆柱状、球形等，但不限于此。限位部50设于载体40，且与基板外侧面15间隔设置。如此，当基板10的转动角度较大时，基板外侧面15挡止在限位部50，从而限制了基板10的转动角度。
在本实施例中，限位部50和载体40为一体结构，可以理解地，在其他的实施例中，限位部50和载体40为分体结构。如此，将限位部50与载体40设置为分体结构，当其中一者损坏时，只需更换损坏的一者，维修成本较低；将限位部50与载体40设置为一体结构，省略了限位部50与载体40的安装步骤，方便安装。
载体40的背离基板10的一侧还具有一第二装配面43，第二装配面43为平面，第一装配面41和第二装配面43相对设置，载体40还具有形成于第一装配面41和第二装配面43之间的载体外侧面44，限位部50安装于载体外侧面44。具体到本实施例中，限位部50为限位块，限位块通过胶粘接在载体外侧面44。可以理解地，在其他的实施例中，限位块也可通过焊接、卡接等方式固定在载体外侧面44。
移动件20大致为块状结构。
驱动件30包括固定部31和驱动部32。
固定部31设置在载体40的载体外侧面44。驱动部32分别与固定部31和移动件20连接。在本实施例中，移动件20的靠近固定部31的一侧开设形成有固定孔，固定孔可为通孔，也可为盲孔，驱动部32的一端插设于固定孔内且与固定孔过盈配合，以实现驱动部32和移动件20的固定连接。在一些实施例中，驱动部32的一端通过焊接的方式固定连接在移动件20的一侧。可以理解地，驱动部32和移动件20的连接还可采用其他的固定连接方式，例如胶粘等，在 此不作具体限制。在一些实施例中，驱动部32和固定部31为一体式结构，此时，驱动件30为压电陶瓷杆。在一些实施例中，驱动部32和固定部31为分体式结构，此时，驱动部32和固定部31可组成丝杠螺母驱动结构。在一些实施例中，驱动件30包括但不限于是步进马达(Stepping Motor，SM)、音圈马达(Voice Coil Motor，VCM)、压电马达(Piezoelectric Motor，PM)和微机电系统(Micro-electromechanical Systems，MEMS)。例如，当第一驱动件30为音圈马达时，固定部31为载体外侧面44的定子，驱动部32为动子，动子与移动件20连接，并可带动移动件20沿直线运动。可以理解地，图示中的结构仅为示意，并不代表实际结构。其他马达的连接关系与音圈马达类似，故不再做具体说明。
光学防抖驱动器100还包括导通件(图未示)，导通件设于驱动件的一侧，导通件的一端与驱动件30的驱动部32电连接，另一端与外部电路连接。如此，可实现驱动件30与外部电路的导通，在图1中，光学组件300为电路板和设置在电路板上的感光芯片，导通件的另一端与电路板上的电路连接。导通件包括但不限于为导线。
可以理解地，在其他的实施例中，固定部31设置在载体40的的第一装配面41。
上述的光学防抖驱动器100通过驱动件30驱动移动件20带动光学组件沿直线运动并带动基板10及光学组件300转动，以对镜头的旋转进行补偿，补偿精度高，防抖效果较好，成像质量较高，并且结构简单，体积较小，利于实现电子设备的轻薄化与小型化。
请参见图5，本申请实施例还提出了一种摄像模组400，包括光学防抖驱动器100、壳体200及光学组件300。
壳体200具有一通光孔210，光学防抖驱动器100安装在壳体200内。
光学组件300连接在基板10的第一安装面11，基板10在转动时可带动光学组件300转动。在图5中，摄像模组400还包括镜头310，镜头310固定连接在壳体210的通光孔210处。
上述的摄像模组400包括光学防抖驱动器100，光学防抖驱动器100通过驱动件30驱动移动件20带动光学组件300沿直线运动并带动基板10及光学组件 300转动，以对镜头的旋转进行补偿，补偿精度高，防抖效果较好，成像质量较高，并且结构简单，体积较小，利于实现电子设备的轻薄化与小型化。
