与现有技术相比,本申请具有下列至少一个技术效果:
1、本申请可以通过十字引导结构的设计来减小芯片可x轴y轴两轴移动的摄像模组的z轴高度,还可以确保x轴和y轴移动准直度。
2、本申请的一些实施例中,可以将每个十字引导结构的每个引导槽均设置成具有两个封闭的端面,从而降低十字引导结构中润滑油泄漏的风险,进而提升两轴光学致动模块的整体可靠性。
3、本申请的一些实施例中,通过在载体(或支撑座)的多个引导槽设置成具有不同的引导方向,使得光学致动模块可以避免旋转错位的现象。
4、本申请的一些实施例中,可以通过在支撑座上方布置具有磁轭的定位片,使得定位片可以向支撑座施加z轴方向的压力,这样支撑座和载体之间可以形成z轴方向的预压力,从而将滚珠夹持在中间。同时,定位片和布置在支撑座表面的第一线路板还有助于对支撑座的结构强度进行补强。

具体地,所述驱动组件10包括一防抖固定部11、一防抖可动部12以及一防抖驱动部13。所述防抖固定部11具有一收容腔1101和连通于所述收容腔1101的一顶部开口1102,其中所述感光组件30被设置于所述防抖可动部12,所述防抖可动部12被悬持于所述防抖固定部11的所述收容腔1101,并且所述防抖固定部11的所述顶部开口1102对应于所述感光组件30,其中所述防抖驱动部13用于驱动所述防抖可动部12做相对于所述防抖固定部11的平移和/或旋转运动,以实现所述摄像模组的平移防抖和/或旋转防抖。进一步地,所述防抖固定部11包括一基底111和一上盖112,所述顶部开口1102形成于所述上盖112,所述基底111和所述上盖112被扣合地安装,以在所述基底111和所述上盖112之间形成所述收容腔1101,如此形成于所述基底111和所述上盖112之间的所述收容腔1101连通形成于所述上盖112的所述顶部开口1102。
所述防抖可动部12和所述防抖驱动部13分别被收容于所述防抖固定部11的所述收容腔1101,以由所述防抖固定部11形成所述驱动组件10的外观,通过这样的方式,一方面,所述防抖固定部11能够防止所述防抖可动部12和所述防抖驱动部13被碰撞,以起到保护所述防抖可动部12和所述防抖驱动部13的作用,另一方面,所述防抖固定部11的所述基底111和所述上盖112相互配合而形成密闭的所述收容腔1101,以避免灰尘等污染物进入所述防抖固定部11的所述收容腔1101而污染所述感光元件32和减少杂散光。
优选地,所述防抖固定部11的所述基底111和所述上盖112的材料可以是金属材料,以保证所述驱动组件10的强度。例如,所述防抖固定部11的所述基底111和所述上盖112的材料可以是不锈钢无磁性材料。
可以理解的是,所述摄像模组在实现防抖功能时,所述防抖固定部11的所述基底111和所述上盖112保持不动,以使所述防抖固定部11形成定子。
参考附图1,所述镜头组件20包括一镜头载体21和被设置于所述镜头载体21的一光学镜头22,其中所述镜头载体21被贴装于所述防抖固定部11的所述上盖112,以保持所述光学镜头22于所述感光组件30的感光路径,这样,入射光线在被所述光学镜头22汇聚后能够穿过所述防抖固定部11的所述顶部开口1102而到达所述感光组件30。
值得一提的是,所述镜头载体21的类型在本发明的所述摄像模组中不受限制,例如,在附图1至图6示出的所述摄像模组的这个具体示例中,所述镜头载体21是驱动载体,以用于驱动所述光学镜头22沿着所述摄像模组的光轴方向运动而实现所述摄像模组的变焦和/或对焦,或者用于驱动所述光学镜头22平移而实现所述摄像模组的防抖。例如,所述镜头载体21可以通过线圈和磁石相互配合的方式驱动所述光学镜头22。再例如,所述镜头载体21可以是但不限于音圈马达、压电马达、SMA(Shape Memory Alloy)马达。可选地,在本发明的所述摄像模组的另外一些具体示例中,所述镜头载体21可以是镜筒,其用于保持所述光学镜头22于所述感光组件30的感光路径。
还值得一提的是,在本发明的所述摄像模组的另外一些具体示例中,所述镜头组件20可以没有所述镜头载体21,此时,所述光学镜头22被直接地贴装于所述防抖固定部11的所述上盖112而被保持在所述感光组件30的感光路径。
继续参考附图1至图6,所述感光组件30包括一电路板31和被连接于所述电路板31的一感光元件32,其中所述电路板31被设置于所述防抖可动部12,以设置所述感光组件30于所述防抖可动部12。
所述感光组件30进一步包括一系列电子元器件33,其可以是但不限于电阻、电容、处理器等被动元器件,其中这些所述电子元器件33被贴装于所述电路板31。
另外,所述感光组件30还可以包括滤光片,例如红外截止滤光片,其被保持在所述感光元件32的感光路径。
参考附图1至图3B,所述电路板31具有两延伸臂311,两个所述延伸臂311分别于所述电路板31的相对两侧经所述基底111和所述上盖112的连接位置延伸至所述防抖固定部11的外部并进一步向上延伸,如此在所述防抖可动部12被所述防抖驱动部13驱动而于所述防抖固定部11的所述收容腔1101做平移和/或旋转运动时,能够保证稳定并减少阻力。可选地,两个所述延伸臂311能够于所述电路板31的相邻两侧经所述基底111和所述上盖112的连接位置延伸至所述防抖固定部11的外部并进一步向上延伸。
继续参考附图1至图6,所述防抖可动部12包括一可动载体121和一组滚珠122,其中一组所述滚珠122被可滚动地设置于所述可动载体121和所述上盖112之间,以使所述防抖可动部12和所述防抖固定部11之间点摩擦接触,从而保证所述防抖驱动部13顺畅地驱动所述防抖可动部12做相对于所述防抖固定部11的平移和/或旋转运动。
具体地,所述可动载体121具有一载体正面1211、相对于所述载体正面1211的一载体背面1212以及自所述载体正面1211延伸至所述载体背面1212的一载体开口1213。所述感光组件30的所述电路板31被设置于所述可动载体121的所述载体背面1212,并且所述感光组件30的所述感光元件32和所述可动载体121的所述载体开口1213相对应,如此入射光线被允许经过所述可动载体121的所述载体开口1213到达所述感光元件32。
所述感光组件30的所述电路板31和所述防抖固定部11的所述基底111之间具有间隙,一组所述滚珠122被可滚动地设置于所述可动载体121的所述载体正面1211和所述上盖112的内壁之间,以使所述防抖可动部12和所述防抖固定 部11之间点摩擦接触,如此所述防抖驱动部13顺畅地驱动所述防抖可动部12做相对于所述防抖固定部11的平移和/或旋转运动。
可选地,在本发明的所述摄像模组的一些具体示例中,所述感光组件30能够被嵌入所述可动载体121的所述载体开口1213,以有利于降低所述摄像模组的高度尺寸。换言之,所述可动载体121被设置环绕于所述感光组件30的四周。此时,一方面,所述可动载体121的所述载体背面1212和所述防抖固定部11的所述基底111之间具有间隙,另一方面,所述可动载体121的所述载体正面1211和所述防抖固定部11的所述上盖112的内壁之间设置有可滚动的一组所述滚珠122,从而悬持所述防抖可动部12于所述防抖固定部11的所述收容腔1101,以保证所述防抖驱动部13能够顺畅地驱动所述防抖可动部12做相对于所述防抖固定部11的平移和/或旋转运动。
可选地,在本发明的所述摄像模组的一些具体示例中,所述感光组件30的所述电路板31被贴装于所述可动载体121的所述载体正面1211。此时,一方面,所述可动载体121的所述载体背面1212和所述防抖固定部11的所述基底111之间具有间隙,另一方面,所述可动载体121的所述载体正面1211和所述防抖固定部11的所述上盖112的内壁之间设置有可滚动的一组所述滚珠122,并且一组所述滚珠122保证感光组件30和所述上盖112之间具有间隙,从而悬持所述防抖可动部12于所述防抖固定部11的所述收容腔1101,以保证所述防抖驱动部13能够顺畅地驱动所述防抖可动部12做相对于所述防抖固定部11的平移和/或旋转运动。可以理解的是,在所述感光组件30的所述电路板31被贴装于所述可动载体121的所述载体正面1211的这些示例中,所述可动载体121可以不需要设置所述载体开口1213。
继续参考附图1至图6,所述防抖驱动部13包括多个防抖磁石131和多个防抖线圈132,这些所述防抖磁石131分别被设置于所述防抖固定部11,这些所述防抖线圈132分别被设置于所述防抖可动部12,并且这些所述防抖磁石131和这些所述防抖线圈132相对应,其中这些所述防抖线圈132通电后产生的磁场和这些所述防抖磁石131的磁场能够相互作用,以驱动所述防抖可动部12做相对于所述防抖固定部11的平移和/或旋转运动,从而实现所述摄像模组的平移防抖和/或旋转防抖。例如,所述防抖驱动部13的这些所述防抖磁石131和这些所述防抖线圈132能够相互作用,以驱动所述防抖可动部12相对于所述防抖固定 部11产生沿X轴方向和/或Y轴方向的平移运动而实现所述摄像模组的平移防抖。所述防抖驱动部13的这些所述防抖磁石131和这些所述防抖线圈132能够相互作用,以驱动所述防抖可动部12相对于所述防抖固定部11产生绕Z轴方向的旋转运动而实现所述摄像模组的旋转防抖。
优选地,在附图1至图6示出的所述摄像模组中,所述防抖驱动部13的这些所述防抖磁石131分别被设置于所述防抖固定部11的所述上盖112,相应地,所述防抖驱动部13的这些所述防抖线圈132分别被设置于所述防抖可动部12,并且每个所述防抖磁石131和每个所述防抖线圈132一一对应。例如,从附图1示出的方向来看,所述防抖磁石131位于所述防抖线圈132的上方,即,所述防抖磁石131和所述防抖线圈132采用上下布置的方式。
进一步地,所述驱动组件10包括至少一导磁构件14,所述导磁构件14被罩设在所述防抖磁石131的上方,如此:一方面,所述导磁构件14能够向下(即,所述防抖线圈132所在的方向)加强磁场强度,以使所述防抖驱动部13具有足够的驱动力来驱动所述防抖可动部12做相对于所述防抖固定部11的平移和/或旋转运动,另一方面,所述导磁构件14能够避免朝向所述镜头载体21的方向漏磁而干扰所述镜头载体21的磁场。
换言之,对于在所述镜头载体21设置磁石以实现对焦、变焦和/或防抖功能的所述摄像模组而言,通过在所述防抖驱动部13的所述防抖磁石131的上方罩设所述导磁构件14的方式能够隔离所述镜头载体21的磁场和所述防抖驱动部13的磁场,从而避免两者相互干扰而保证所述摄像模组的可靠性、稳定性。
具体地,所述导磁构件14被设置于所述防抖固定部11的所述上盖112,所述防抖磁石131被设置于所述导磁构件14,即,所述防抖磁石131通过被设置于所述导磁构件14的方式被设置于所述上盖112,如此能够保持所述导磁构件14于所述防抖磁石131和所述上盖112之间。通过这样的结构设计,所述导磁构件14允许所述防抖磁石131的磁力线朝向所述防抖线圈132的方向集中,以增加所述防抖驱动部13的磁场强度,同时减少外溢到所述镜头载体21的磁场强度,从而避免对所述镜头载体21产生磁干扰。
更具体地,沿所述摄像模组的光轴一侧看其平面,所述导磁构件14呈四边形结构,所述导磁构件14的面积大于或等于所述防抖磁石131的面积,并且所述导磁构件14完全覆盖所述导磁构件131,如此所述导磁构件14能够有效地防 止所述防抖磁石131的磁力外泄。换言之,所述导磁构件14覆盖所述防抖磁石131的朝向所述光学镜头22的表面。例如,在本发明的所述摄像模组的一个具体示例中,所述导磁构件14的形状和所述防抖磁石131的形状相同,即,所述导磁构件14是一个呈方形的平板,其被罩设于所述防抖磁石131的上方而将所述防抖磁石131的上表面完全遮盖。
优选地,在附图1至图6示出的本发明的所述摄像模组的这个具体示例中,所述导磁构件14的形状和所述防抖磁石131的形状不同,例如,所述导磁构件14呈具有开口的“U”型,其不仅能够遮盖所述防抖磁石131的上表面,而且能够包裹所述防抖磁石131的相对两个侧面的至少一部分,以使所述防抖磁石131的磁力线朝向所述防抖线圈132的方向集中。
值得一提的是,所述导磁构件14的数量和所述防抖磁石131的数量的对应关系在本发明的所述摄像模组中不受限制。例如,在附图1至图6示出的本发明的所述摄像模组的这个具体示例中,所述导磁构件14的数量和所述防抖磁石131的数量一致,这样,在每个所述防抖磁石131的上方可以分别罩设一个所述导磁构件14,如此所述导磁构件14和所述防抖磁石131可以一一对应。可选地,在本发明的所述摄像模组的另一些示例中,所述导磁构件14的数量少于所述防抖磁石131的数量,这样,一个所述导磁构件14能够罩设在至少两个所述防抖磁石131的上方。
本领域技术人员可以理解的是,参考附图5和图6,所述感光组件30的所述感光元件32呈矩形,其具有四个侧边。为了便于描述和理解,沿着顺时针方向,所述感光元件32的四个侧边依次被定义为一第一芯片侧边321、一第二芯片侧边322、一第三芯片侧边323以及一第四芯片侧边324,以所述感光元件32的中心点为原点、以平行于所述第一芯片侧边321和所述第三芯片侧边323的方向为X轴方向、以平行于所述第二芯片侧边322和所述第四芯片侧边324的方向为Y轴方向、以垂直于所述感光元件32的感光面的方向为Z轴方向建立坐标系。
根据所述防抖驱动部13的这些所述防抖线圈132的设置位置,这些所述防抖线圈132形成一第一线圈组133、一第二线圈组134以及一第三线圈组135,其中在X轴和Y轴所在的平面,所述第一线圈组133沿着Y轴方向设置,所述第二线圈组134和所述第三线圈组135分别沿着X轴方向设置,并且所述第二线圈组134和所述第三线圈组135位于所述感光元件32的相对两侧,如此使得所述 防抖驱动部13的这些所述防抖线圈132环绕于所述感光组件30的所述感光元件32的四周。优选地,所述第二线圈组134和所述第三线圈组135相对于Y轴对称。可以理解的是,所述第二线圈组134和所述第三线圈组135位于所述防抖固定部11的所述顶部开口1102的相对两侧。
组成所述第一线圈组133的所述防抖线圈132的数量为至少一个,组成所述第二线圈组134的所述防抖线圈132的数量为至少两个,组成所述第三线圈组135的所述防抖线圈132的数量为至少两个。优选地,在附图1至图6示出的所述摄像模组的这个具体示例中,组成所述第一线圈组133、所述第二线圈组134和所述第三线圈组135的所述防抖线圈132的数量均为两个。
具体地,组成所述第一线圈组133的两个所述防抖线圈132分别被定义为一第一线圈1321和一第二线圈1322,所述第一线圈1321和所述第二线圈1322沿着Y轴方向相对且平行设置;组成所述第二线圈组134的两个所述防抖线圈132分别被定义为一第三线圈1323和一第四线圈1324,所述第三线圈1323和所述第四线圈1324沿着X轴方向相对且平行设置;组成所述第三线圈组135的两个所述防抖线圈132分别被定义为一第五线圈1325和一第六线圈1326,所述第五线圈1325和所述第六线圈1326相对且平行设置。
换言之,所述第一线圈1321和所述第二线圈1322分别被设置于所述感光元件32的所述第四芯片侧边324和所述第二芯片侧边322,并且所述第一线圈1321和所述第二线圈1322分别平行于所述感光元件32的所述第四芯片侧边324和所述第二芯片侧边322。所述第三线圈1323和所述第五线圈1325分别被设置于所述感光元件32的所述第一芯片侧边321,并且所述第三线圈1323和所述第五线圈1325分别平行于所述感光元件32的所述第一芯片侧边321。所述第四线圈1324和所述第六线圈1326分别被设置于所述感光元件32的所述第三芯片侧边324,并且所述第四线圈1324和所述第六线圈1326分别平行于所述感光元件32的所述第三芯片侧边323。

优选地,在附图1至图6示出的所述摄像模组的这个具体示例中,所述驱动组件10包括四个所述支撑部17,其分别被设置于所述第一位置组12101和所述第二位置组12102之间以及位于所述第二位置组12102和所述第三位置组12103之间。也就是说,所述驱动组件10的四个所述支撑部17分别位于所述防抖可动部12的四个转角处,以为所述防抖可动部12提供更平稳的支撑,同时充分利用所述驱动组件10的内部空间而使所述驱动组件10的结构更紧凑。可选地,在本发明的所述摄像模组的另外一些示例中,所述驱动组件10的所述支撑部17可以是滑块,其被可滑动地保持在所述可动载体121和所述上盖112之间,以用于平稳支撑所述防抖可动部12。继续参考附图1至图6,所述驱动组件10包括四个所述磁吸构件15,每个所述磁吸构件15分别被设置于所述防抖可动部12的每个转角处,如此能够保证所述防抖可动部12的平整度而使所述摄像模组的光轴能够垂直于所述感光组件30的所述感光元件32的感光面。
继续参考附图1至图6,在本发明的所述摄像模组的这个具体示例中,所述磁吸构件15被设置于所述电连接部123,以优化所述摄像模组的结构。可选地, 在本发明的所述摄像模组的另外一些示例中,所述磁吸构件15可以被设置于所述可动载体121,或者所述磁吸构件15可以被设置于所述感光组件30的所述电路板31,或者所述磁吸构件15被设置于所述可动载体121和所述电连接部123之间,或者所述磁吸构件15可以被设置于所述电连接部123和所述电路板31之间。
另外,在本发明的所述摄像模组的一些示例中,所述磁吸构件15和所述防抖驱动部13的所述防抖磁石131可以完全对准,即,所述磁吸构件15可以位于所述防抖驱动部13的所述防抖磁石131的正下方。在本发明的所述摄像模组的另一些示例中,所述磁吸构件15和所述防抖驱动部13的所述防抖磁石131可以没有完全对准,两者之间存在一些偏差。
可以理解的是,在所述防抖驱动部13驱动所述防抖可动部12做相对于所述防抖固定部11的平移和/或旋转运动时,所述磁吸构件15会同步地产生相对于所述防抖固定部11的平移和/或旋转运动,此时,所述磁吸构件15和所述防抖磁石131之间也会产生一些偏差,但是所述磁吸构件15所在的平面和所述防抖磁石131所在的平面始终是平行的,即,所述磁吸构件15所在的平面和所述防抖磁石131所在的平面始终正交于Z轴,因此,所述磁吸构件15和所述防抖磁石131能够相互配合而在Z轴方向产生磁吸力是指所述磁吸构件15所在的平面和所述防抖磁石131所在的平面之间的磁吸力,包括但不限于竖直方向的磁吸力、偏移竖直方向的倾斜磁吸力。
继续参考附图1至图6,所述驱动组件10进一步包括至少三防抖位置感测元件16,其分别通过感测所述第一磁石组136、所述第二磁石组137和所述第三磁石组138的位置信息的方式感测所述防抖可动部12于X轴方向平移、Y轴方向平移、Z轴方向旋转的位置信息。
优选地,三个所述防抖位置感测元件16分别被定义为一第一感测元件161、一第二感测元件162以及一第三感测元件163。所述第一感测元件161被设置于所述第一线圈1321的所述线圈空间13202,以对应于所述第一磁石1311,其中所述第一感测元件161用于感测X轴方向平移时的磁场变化。所述第二感测元件162被设置于所述第四线圈1324的所述线圈空间13202,以对应于所述第四磁石1314,其中所述第二感测元件162用以感测Y轴方向平移时的磁场变化。所述第三感测元件163被设置于所述第五线圈1325的所述线圈空间13202,以对应于 所述第五磁石1315,其中所述第二感测元件162和所述第三感测元件163用于感测Z轴方向旋转时的磁场变化。
优选地,所述防抖位置感测元件16被贴装于所述电连接部123。
在本发明的所述摄像模组中,所述防抖驱动部13的所述第一线圈组133、所述第二线圈组134和所述第三线圈组135是独立控制的线圈组,因此仅需设置三个所述防抖位置感测元件16即可,如此不仅能够减少所述驱动组件10的元件数量,利用较少的数量接口实现平移防抖和/或旋转防抖的感测而有利于减小所述驱动组件10的尺寸,而且能够充分地利用所述驱动组件10的内部空间而使得所述驱动组件10的结构紧凑。
值得一提的是,在本发明的所述摄像模组的一些实施例中,所述防抖位置感测元件16可以是霍尔元件。在发明的所述摄像模组的另一些实施例中,所述防抖位置感测元件16可以是驱动IC,其适于在获取所述防抖磁石131的位置变化的同时控制所述防抖线圈132的电流。具体地,当所述摄像模组开启防抖功能后,所述防抖位置感测元件16能够感测当前的所述第一磁石组136、所述第二磁石组137和所述第三磁石组138的当前位置,并通过控制所述第一线圈组133、所述第二线圈组134和所述第三线圈组135的电流的方式驱动所述防抖可动部12移动至感测的中心位置,当所述摄像模组关闭防抖功能后,通过所述感光组件30的所述电路板31的反发力(即,所述防抖可动部12在被平移和/或旋转时,所述电路板31因产生弹性形变而积蓄的弹性力)使得所述防抖可动部12返回至初始位置。
附图7示出了本发明的所述摄像模组的一个变形示例,与附图1至图6示出的所述摄像模组不同的是,在附图7示出的所述摄像模组的这个变形示例中,所述第一线圈组133包括四个所述防抖线圈132,其中组成所述第一线圈组133的两个所述防抖线圈132相互对称地设置在所述感光元件32的所述第二芯片侧边322和所述第四芯片侧边324中的一端,另外两个所述防抖线圈132相互对称地设置在所述感光元件32的所述第二芯片侧边322和所述第四芯片侧边324中的另外一端。所述可动载体121的四个所述保持槽1215分别形成于所述感光元件32的所述第一芯片侧边321、所述第二芯片侧边322、所述第三芯片侧边323和所述第四芯片侧边324的中部,如此使得四个所述滚珠122分别于所述感光元件32的所述第一芯片侧边321、所述第二芯片侧边322、所述第三芯片侧边323和 所述第四芯片侧边324的中部被可滚动地保持在所述可动载体121的所述载体正面1211和所述上盖112的内壁之间。

在附图10示出的所述摄像模组的这个变形示例中,所述驱动组件10的所述导磁构件14位于所述防抖磁石131的下方,如此:一方面,所述导磁构件14能够向上(即,所述防抖线圈132所在的方向)加强磁场强度,以使所述防抖驱动部13具有足够的驱动力来驱动所述防抖可动部12做相对于所述防抖固定部11的平移和/或旋转运动;另一方面,所述导磁构件14能够阻止所述防抖磁石131的磁场外泄,而避免干扰所述感光组件30的所述电路板31和所述感光元件32。
具体地,所述导磁构件14被设置于所述可动载体121,所述防抖磁石131被设置于所述导磁构件14,即,所述防抖磁石131通过被设置于所述导磁构件14的方式被设置于所述可动载体121。

图17示出了本申请一个实施例中的基于滚珠的两轴光学致动模块的立体示意图,图18示出了本申请一个实施例中的基于滚珠的两轴光学致动模块的立体分解示意图。结合参考图17和图18,根据本发明的一个实施例,提供了一种基于滚珠的两轴光学致动模块,其用于实现感光芯片在x轴和y轴上的受控移动。具体来说,该光学致动模块包括静态部件、动态部件和驱动元件。其中,静态部件包括一底座620和一支撑座500,支撑座500位于底座620的上方并与底座620固定在一起。支撑座500和底座620之间可以形成一容纳感光芯片及其附属构件的腔体。进一步地,所述支撑座500具有平行于基准面的第一表面501(结合参考图19,图19示出了本申请一个实施例中的支撑座500的背面视角下的立体示意图)。本实施例中,基准面即xoy平面,x轴和y轴均为基准面上的坐标轴,且二者互相垂直。本实施例中,动态部件包括一载体610,其用于搭载光学组件,所述光学组件包括感光芯片。具体来说,该光学组件可以包括感光芯片、芯片线路板、安装于芯片线路板上的电子元件、滤光片和滤光片支架等,为便于描述,可以将该光学组件称为芯片组合体。需要注意,在其他实施例中,载体610所搭载的光学组件也可以是包含透镜的光学组件,例如光学镜头或透镜组。本实施例中,所述载体610具有平行于所述基准面的第二表面611,所述支撑座500与所述载体610上下叠置,并且所述第一表面501面对所述第二表面611。所述芯片组合体630可以位于支撑座500的下方,即芯片组合体630布置在底座620和支撑座500之间所形成的腔体内,从而将感光芯片封装在静态部件的内部。所述驱动元件用于提供驱动力以带动所述动态部件相对于所述静态部件移动。本实施例中,驱动元件可以是线圈820和磁体810的组合。即驱动元件为电磁驱动元件,但需要注意,本申请的其他实施例中,也可以采用其他类型的驱动元件(例如步进电机、SMA线、压电驱动元件等)来驱动所述感光芯片移动。本实施例中,所述支撑座500的第一表面501和所述载体610的第二表面611之间设置至少一个十字引导结构。其中所述十字引导结构由位于所述第一表面501的第一引导槽505和位于所述第二表面611的第二引导槽612共同构成,并且在同一个所述十字引导结构中,所述第一引导槽505和所述第二引导槽612的引导方向是正交的。本实施例中,所述第一引导槽505具有两个封闭的端面,并且其面向所述第二表面611的一侧开口;所述第二引导槽612也具有两个封闭的端面,并且其面向所 述第一表面501的一侧开口,所述十字引导结构的交叉位置设置单颗滚珠507。具体来说,引导槽具有平行于其引导方向的轴线,大致垂直于其轴线的槽壁面称为端面,位于其轴线两侧并大致平行于其轴线的槽壁面称为侧面。本实施例中,引导槽的两个侧面可以倾斜设置,形成V型形状。即引导槽的两个侧面可以倾斜设置,使得引导槽的宽度由其槽底面至其开口侧逐渐增大。这里引导槽既包括第一引导槽505,也包括第二引导槽612。即第一引导槽505和第二引导槽612均具有上述倾斜设置的两个侧面。这种设计可以使得十字引导结构更好地在两轴方向引导滚珠的移动,避免引导槽过度限位导致滚珠卡死。本实施例中,基于十字引导结构,可以使用单层滚珠来实现光学元件(例如感光芯片)在两个轴向上的移动,从而减小模组z轴的高度。同时,相比矩形容纳槽等方案,本实施例的十字引导结构可以更好地确保x轴和y轴移动的准直度。
需要注意,上述实施例中,引导槽均具有两个封闭的端面是一种可以提升两轴光学致动模块可靠性的特殊设计。在现有技术的范畴或观念中,对于摄像模组领域量产产品的滚珠结构,人们通常倾向于沿用已有的成熟设计,以便提升产品的可靠性。现有摄像模组的滚珠结构中,其支撑件的引导槽通常会保留一个不封闭的端面,即在支撑件上开槽时,直接将该支撑件的一个外侧面打通,使引导槽的一个端面暴露在外。这种设计一方面可以降低滚珠槽的加工难度,另一方面也便于在支撑件装配完成后,从该不封闭的端面将滚珠塞入引导结构中。这种设计思路下,由于滚珠最后塞入,所以支撑件在装配过程中更易于固定,有助于降低组装工艺的难度。本申请的发明人深入研究,发现十字引导结构的引导槽内润滑油存在泄漏风险(第一引导槽505和第二引导槽612仅在交叉位置互相正对,形成大致封闭的结构,而对于非交叉位置,位于上方的引导槽中的润滑油可能向下流动或滴落至下方引导槽以外的区域,从而导致润滑油向外泄漏),而将引导槽的所有端面均设计为封闭端面,则封闭端面可以阻滞润滑油的流动,并显著减小或消除润滑油泄漏的问题。基于上述发现,申请人克服现有技术的窠臼,将十字引导结构中的引导槽均设计成两端均具有封闭端面的形式,进而显著地降低润滑油泄漏的风险,综合评估中,能够提升了量产产品的整体可靠性。需要注意的是,虽然上述实施例中,十字引导结构的每个引导槽的两端均具有封闭的端面,但本申请的其他实施例中,十字引导结构的引导槽也可以具有不封闭的端面(即引导槽的一端一直延伸到支撑件的外侧边沿,使得该引导槽的至少一个端面暴露在 外)。基于这种十字引导结构,同样可以使用单层滚珠来实现光学元件(例如感光芯片)在两个轴向上的移动,从而减小模组z轴的高度。
进一步地,结合参考图18和图19,本申请的一个实施例中,所述第一表面501具有至少一个x轴滚珠引导槽和至少一个y轴滚珠引导槽;所述第二表面611也具有至少一个x轴滚珠引导槽和至少一个y轴滚珠引导槽;所述第一表面501的一个所述x轴滚珠引导槽与所述第二表面611的一个所述y轴滚珠引导槽构造成一个所述的十字引导结构,所述第一表面501的一个所述y轴滚珠引导槽与所述第二表面611的一个所述x轴滚珠引导槽构造成另一个所述的十字引导结构;其中,x轴和y轴是所述基准面上两个互相垂直的坐标轴。图17和图19中示出三维直角坐标系中的x轴、y轴和z轴。z轴是垂直于所述基准面的坐标轴。在本领域普通技术人员的常规思路中,当同一个载体610(或同一个支撑件)的同一表面(这里同一表面指的是同一侧的表面,例如载体610的正面或上表面,支撑座500的背面或下表面)上设置有多个滚珠引导槽时,会将这些引导槽的引导方向设计成完全一致。例如一个支撑件的下表面上全部是x轴引导槽,则另一个位于下方的支撑件的上表面上则全部是y轴引导槽。而本申请的发明人发现,对于十字引导结构,由于每个引导结构中仅具有单颗滚珠507,且由于引导槽加工精度有限,该滚珠有一定几率出现错位现象,导致载体610相对于支撑座500旋转(指在xoy平面内的旋转),即出现旋转错位的现象。可参考图20a,图20a示出了同一表面引导槽走向相同时的旋转错位现象的示意图。例如,假设支撑座500上的第一表面的引导槽全部是y轴引导槽,那么在摄像模组遭到撞击或其他外力作用时,滚珠可能顶起载体,通过第二引导槽的较宽的区域(引导槽的槽底面至开口面往往是宽度逐渐增大的)移动到如图20a所示的位置,从而导致载体相对于支撑座发生旋转错位。图20a中的虚线示出了发生旋转错位后的载体的第二表面上的第二引导槽的大致方向。可以看出,旋转错位后,第二引导槽偏离了x轴方向。而在本实施例中,采用将x轴、y轴引导槽布置在同一表面的设计,可以避免上述旋转错位的现象,或者说可以降低载体相对于支撑座旋转错位的风险。
进一步地,本申请的一个实施例中,所述第一表面501和所述第二表面611之间设置四个所述的十字引导结构;在俯视角度下,所述支撑座500和所述载体610的外轮廓呈矩形,四个所述的十字引导结构分别设置在所述支撑座500和所述载体610的四角区域。在俯视角度下,所述支撑座500具有第一边501a和位 于其另一侧的第二边501b(结合参考图20b,图20b示出了本申请一个实施例中的支撑座的第一表面上的四个第一引导槽的引导方向),位于所述第一边501a的两个角落区域的两个所述十字引导结构具有位于所述第一表面501的x轴滚珠引导槽和位于所述第二表面611的y轴滚珠引导槽;位于所述第二边501b的两个角落区域的两个所述十字引导结构具有位于所述第二表面611的x轴滚珠引导槽和位于所述第一表面501的y轴滚珠引导槽。
进一步地,图21示出了本申请一个实施例中两轴光学致动模块去除支撑座后的立体示意图。结合参考图17、图18、图19和图21,本申请的一个实施例中,所述驱动元件包括磁体810和线圈820,所述磁体810安装于所述载体610的所述第二表面611,所述线圈820安装于所述支撑座500。所述支撑座500还具有背向所述载体610的第三表面502(本实施例中第三表面502为支撑座500的上表面),所述支撑座500设置多个贯穿所述第一表面501和所述第三表面502的避让孔503,所述载体610和所述支撑座500装配在一起后,所述磁体810位于所述避让孔503中。所述支撑座500的第三表面502安装第一线路板510(本实施例中第一线路板510为支撑座线路板),多个所述线圈820安装于所述第一线路板510的朝向所述载体610的表面,并且所述支撑座500和所述第一线路板510装配在一起后,所述线圈820位于所述避让孔503中。
进一步地,结合参考图17、图18、图19和图21,在本申请的一个实施例中,所述光学致动模块还可以包括一定位片520,所述定位片520位于所述支撑座500的背向所述载体610的一面,并且所述定位片520具有磁轭521;在俯视角度上,所述磁轭521设置在所述磁体810对应的位置处,所述磁轭521与所述磁体810互相吸引,使得所述定位片520将所述支撑座500压在所述载体610上(即定位片可以向支撑座施加z轴方向的压力,这样支撑座和载体之间可以形成z轴方向的预压力,从而将滚珠夹持在中间,进而将所述滚珠限制在所述十字引导结构)。本实施例,所述支撑座500位于所述载体610的上方,所述定位片520位于所述支撑座500的上方,所述支撑座500的上表面安装第一线路板510(本实施例中第一线路板510也可以称为支撑座线路板),多个所述线圈820安装于所述第一线路板510的下表面,并且所述支撑座500和所述第一线路板510装配在一起后,所述线圈820位于所述避让孔503中;所述定位片520具有多个磁轭521,在俯视角度下,多个所述磁轭521分布在各个所述线圈820各自的中央区域。进一步地,参考图17和图18,所述定位片520上可以设置定位孔522, 所述支撑座500上可以设置定位柱506,所述定位片520与支撑座500装配在一起后,所述定位柱506穿过所述定位孔522,从而限制定位片520相对于支撑座在x轴和y轴方向上滑动。再结合所述磁轭521的作用,定位片520即可固定于所述支撑座500的表面。
进一步地,结合参考图17、图18和图19,本申请的一个实施例中,所述支撑座500位于所述载体610上方,所述第一表面501的中央区域向下突出形成一凸块504,所述凸块504中央具有通光孔。所述驱动元件包括磁体810和线圈820,所述磁体810安装于所述载体610的所述第二表面611;所述支撑座500还具有背向所述载体610的第三表面502,所述支撑座500设置多个贯穿所述第一表面501和所述第三表面502的避让孔503,所述避让孔503的至少一个侧壁由所述凸块504的外侧面构成;所述载体610和所述支撑座500装配在一起后,所述磁体810位于所述避让孔503中。本实施例中,一或多个所述磁体810的侧壁和所述凸块504的外侧面可以共同构成坝体,以将所述十字引导结构所处的四角区域与感光芯片所处的中央区域阻隔。这样,即便少量润滑油从十字引导结构中逃逸,也可以被凸块504和磁体810侧壁所构成的坝体所阻隔或者吸附,从而避免润滑油泄漏至中央区域污染感光芯片或成像光路中的其他光学元件。
进一步地,图22示出了本申请一个实施例中的芯片组合体及其芯片线路板。参考图22,本实施例中,所述两轴光学致动器的载体610所搭载的是芯片组合体630。该芯片组合体630可以包括芯片线路板、安装于芯片线路板的感光芯片、形成在所述芯片线路板(也可以称为第二线路板631)表面并围绕在所述感光芯片周围的滤光片支架633,以及安装在滤光片支架633的滤光片632。所述滤光片632、滤光片支架633和芯片线路板可以将感光芯片封装在内部,从而保护感光芯片。滤光片支架633可以通过模塑工艺直接成型于芯片线路板的表面。进一步地,所述芯片线路板可以包括提供芯片承靠面的硬板和将硬板中的线路引出的可折叠线路板631a。所述可折叠线路板631a具有多段软板以形成多个弯折。在一些实施例中,所述可折叠线路板631a可以是软硬结合板,在另一些实施例中,所述可折叠线路板631a可以是纯软板。本实施例中,所述支撑座500可以具有侧壁,所述可折叠线路板631a可以围绕并承靠于所述侧壁外侧面。所述支撑座500的侧壁可以不连续不完整的侧壁,只要可以对可折叠线路板631a的形状进行辅助定型即可。进一步地,图23示出了本申请一个实施例中的绘制出围绕在支撑座周围的线路板的光学致动模块的立体示意图。参考图23,所述芯片线路 板可以通过所述可折叠线路板631a延伸至所述支撑座500的外周,并与所述第一线路板510(即支撑座线路板)导通,进而通过同一连接器634来电连接手机(或其他搭载摄像模组的电子设备)的主板。本实施例中,第一线路板510也可以从支撑座500的侧面引出,并围绕和承靠于支撑座500的外侧面。
上述实施例中,四个十字引导结构布置在载体和支撑座的四角位置,然而本申请并不限于此。例如,本申请的一些实施例中,所述第一表面和所述第二表面之间设置三个或五个所述的十字引导结构。每个所述十字引导结构中设置单颗所述的滚珠。一般来说,三个点可以比较稳定地支撑一个平面,所以可以使用三个滚珠对支撑件(例如支撑座和载体)进行支撑。即,在本申请的一些实施例中,在所述第一表面和第二表面之间,至少三个所述的十字引导结构。所述第一表面和所述第二表面之间,全部使用十字引导结构来容纳滚珠,可以为载体的移动提供更好的x轴和y轴移动的准直度。然而需注意,在另外一些实施例中,部分十字引导结构可以被滚珠容纳结构所替代。
进一步地,本申请的另一些实施例中,可以将部分十字引导结构替换为更为简单的滚珠容纳结构,该滚珠容纳结构中放置滚珠并容许该滚珠在xoy平面内移动即可。例如,在俯视角度下,所述滚珠容纳结构可以是矩形的,即所述滚珠容纳结构可以是矩形槽形状的滚珠容纳结构。在本申请的一些实施例中,所述第一表面501和所述第二表面之间,所述的十字引导结构和所述的滚珠容纳结构的总数至少为三个,所述的十字引导结构和所述的滚珠容纳结构共同在z轴方向支撑所述支撑座和载体。用矩形槽形状的滚珠容纳结构来替换部分的十字引导结构,可以有助于降低加工工艺难度,从而节省成本。
进一步地,本申请的一些实施例中,还提供了基于上述两轴光学致动模块的摄像模组。该摄像模组可以包括感光组件和镜头组件,其中镜头组件包括用于移动镜头的光学致动器和安装于该光学致动器的光学镜头。感光组件可以包括前文所述的两轴光学致动模块和安装于其中的芯片组合体(也可以是含有感光芯片的其他光学组件)。
本申请的一些实施例中,所述的基于滚珠的两轴光学致动模块可以与用于移动镜头的伸缩式光学致动器配合使用,以构成感光芯片移动实现光学防抖、镜头可伸缩的伸缩式摄像模组。本实施例中,支撑座既可作为伸缩式光学致动器的静态部件,也可以作为用于移动感光芯片的两轴光学致动模块的静态部件。也就是说,镜头组件和感光组件可以共用同一支撑座。
进一步地,图24示出了本申请一个实施例中的伸缩式摄像模组的立体结构示意图;图25a示出了本申请一个实施例中的伸缩式摄像模组在收缩状态下的外观示意图;图25b示出了本申请一个实施例中的伸缩式摄像模组在伸展状态下的外观示意图;图26示出了本申请一个实施例中的光学镜头和镜头载体的立体结构示意图;图27示出了本申请一个实施例的伸缩式摄像模组在去除壳体和分隔组件后的第一视角下的立体示意图;图28示出了本申请一个实施例的伸缩式摄像模组在去除壳体和分隔组件后的第二视角下的立体示意图。结合参考图24、图25a、图25b和图26,本实施例中,光学致动器可以包括:壳体100、镜头载体200、驱动装置300以及分隔组件400。壳体100顶部具有一壳体通光孔101。镜头载体200可以包括筒状部210和自所述筒状部210底部向外延伸而形成的平板部220。驱动装置300适于驱动所述镜头载体200相对于所述壳体100沿着所述筒状部210的轴线移动,所述筒状部210适于在所述驱动装置300的作用下从所述壳体通光孔101伸出或缩进所述壳体100。分隔组件400的顶部和底部分别连接所述壳体100的顶盖的下表面和所述平板部220的上表面。所述分隔组件400包括一筒形的分隔膜,所述分隔膜环绕在所述筒状部210的周围,并且所述分隔膜的筒壁折叠成波纹状,使其适于在所述筒状部210的轴线方向上伸缩。分隔组件400可以实现防尘效果。当分隔组件使用防水材料制作分隔膜,并且分隔组件400的顶面和底面分别使用防水胶粘结所述壳体100的顶盖的下表面和所述平板部220的上表面时,该分隔组件400可以实现防水的技术效果。
进一步地,结合参考图26和图27,在本申请的一个实施例中,所述伸缩式光学致动器的镜头载体200中,所述筒状部210内侧面适于安装光学镜头700。本实施例中,所述筒状部210的顶部可以具有台阶结构211,一透光盖片240安装于所述台阶结构211并将所述光学镜头700封装在所述筒状部210的内部(结合参考图24-图27)。具体来说,所述台阶结构211包括一环形水平台阶面212和一环形侧壁213,所述透光盖片240的底面通过防水胶固定于所述环形水平台阶面212,从而使得光学致动器和相应摄像模组具有更好的防水效果。进一步地,在本申请的一个实施例中,所述透光盖片240与所述台阶结构211的所述环形侧壁213之间的间隙也可以布置有所述防水胶,从而增强光学致动器和相应摄像模组的防水能力。
进一步地,结合参考图27和图28,在本申请的一个实施例中,所述驱动装置300可以包括压电驱动装置310。所述伸缩式光学致动器还包括与所述壳体100 连接固定的支撑座500,所述压电驱动装置310包括固定部311、驱动杆312、压电元件313和移动部314,所述固定部311固定于所述支撑座500,所述移动部314与所述平板部220固定,所述驱动杆312的一端固定于所述压电元件313,并且所述驱动杆312的轴线方向平行于所述筒状部210的轴线方向;所述移动部314通过摩擦件与所述驱动杆312活动连接,所述压电元件313安装于所述固定部311并适于在所述驱动杆312轴线的方向上振动,以驱动所述移动部314相对于所述驱动杆312沿着所述驱动杆312的轴线移动。本实施例中,所述支撑座500位于所述壳体100的底部,所述支撑座500具有中央通光孔。压电驱动装置310的主体部分(包括固定部311和压电元件313)可以设置在支撑座500上表面与镜头载体200的平板部220的下表面之间的空隙中。
图29示出了本申请一个实施例中的压电驱动组件的结构示意图。参考图29,本实施例中,所述压电驱动组件包括:压电元件313(有时也称作压电素子)、驱动杆312、固定部311(也可以称为配重块)和移动部314(图29中未示出移动部,移动部314可结合参考图27和图28)。其中压电元件313可以安装于固定部311,该压电元件313适于在电压的驱动下产生机械振动。驱动杆312的一端固定于所述压电元件313的振动面。图30示出了一种压电元件及相应驱动杆312实现振动传导功能的示意图。其中,压电元件313可以呈膜状(可将其称为鼓膜),驱动杆312的一端固定于所述压电元件313的中心。压电元件313在电压的驱动下可以在竖直方向上振动,从而推动所述驱动杆312抬升或下降。进一步地,移动部314可以安装于所述驱动杆312上。本实施例中,压电驱动组件可以是基于惯性驱动的压电组件。具体来说,在压电元件的非工作状态下,所述移动部314通过静摩擦力固定于驱动杆312。具体设计上,所述移动部可以具有一通孔,所述驱动杆穿过该通孔,并且通过选择适当的制作材料,移动部的通孔壁与驱动杆的外侧面之间可以形成静摩擦力,该静摩擦力足以支撑所述移动部以及与该移动部连接的套筒等构件的重量,从而保证在压电元件的非工作状态下移动部与驱动杆的相对位置保持不变。当压电元件处于工作状态时,通过控制驱动电压,可以使得压电元件向上移动相对缓慢,从而推动驱动杆相对缓慢地向上移动,此时,由于驱动杆受到的向上的作用力较小,因此移动部与驱动杆之间的接触面的静摩擦力仍然可以移动部与驱动杆的相对固定,这样移动部便随着驱动杆的上升而上升。当压电元件到达最高点后,通过控制驱动电压可以使得压电元件的向下移动相对快速,从而拉动驱动杆相对快速地向下移动,此时,由于驱动杆受到 的向下的作用力较大,移动部与驱动杆之间的接触面的摩擦力不足以保持移动部与驱动杆的相对固定,导致驱动杆相对于移动部向下移动(此时移动部与驱动杆之间的接触面的摩擦力实际上已经转变为动摩擦力)。也就是说,当驱动杆向下移动速度较快时,移动部不会随着驱动杆的下降而下降,而是基本保持在原有高度。当压电元件下降到最低点后,驱动电压再次驱动压电元件缓慢地向上移动,从而再次推动移动部抬升,如此周而复始,即可推动移动部不断向上抬升,直至到达所需的位置。概括地说,可以通过设置驱动电压来控制压电元件缓升急降,使得驱动杆在上升时可以通过静摩擦力的作用带动移动部上升,驱动杆在下降时可以克服动摩擦力而急速下降,避免移动部被驱动杆带着下降。这样,在压电元件的一个振动周期内移动部被有效地抬升。反复执行多个振动周期,移动部便可不断向上抬升,直至到达所需的位置。相反地,通过设置驱动电压来控制压电元件缓降急升,便可以使移动部下降,反复执行多个振动周期,移动部便可不断向下降低,直至到达所需的位置。基于上述原理,移动部便可以在电压信号的控制下,沿着所述驱动杆的方向(例如竖直方向)做双向移动,进而实现套筒的伸缩。以上对基于惯性驱动的压电组件的工作原理做了简要描述,需注意,本申请并不限于此类压电组件。
进一步地,仍然参考图17,在本申请的一个实施例中,所述驱动装置300可以包括压电驱动装置310和附属引导装置320。所述压电驱动装置310的结构及其安装方式可以与前述实施例一致,不再赘述。本实施例中,所述附属引导装置320可以包括轴线与所述驱动杆312平行的导杆321,所述导杆321的底部固定于所述支撑座500,所述镜头载体200的所述平板部220与所述导杆321活动连接。本实施例中,一或多个所述的驱动杆312与一或多个所述的导杆321共同支撑所述镜头载体200。例如,所述镜头载体200的平板部220可以由一个驱动杆312和多个导杆321共同支撑,这些驱动杆312和导杆321可以分别安装于壳体100的四角区域(指俯视角度下的四角区域)。在变形的实施例中,所述驱动杆312和导杆321的总数目可以不为四,例如总数目可以为三个,它们可以分别设置在壳体100的四角区域(指俯视角度下的四角区域)中的三个角落区域。本申请中还可以具有其他变形的实施例,只要压电杆和导杆321可以对镜头载体200的平板部220形成稳定可靠的支撑即可。
进一步地,结合参考图17和图19,在本申请的一个实施例中,所述驱动装置300可以包括压电驱动装置310和附属引导装置320。其中,所述镜头载体200 的平板部220可以具有用于安装压电驱动装置310和附属引导装置320的适配结构。该适配结构可以包括第一适配结构231、第二适配结构232和第三适配结构233。进一步地,结合参考图19、图24和图25,本实施例中,第一适配结构231可以用于安装金属夹持片,该金属夹持片可以弯折并构成一适配孔,所述压电杆从所述适配孔中穿过。所述金属夹持片与所述压电杆的外侧面之间可以设置摩擦件,或者所述压电杆本身可以由摩擦件构成。这样,所述金属夹持片可以作为移动部314,相对于压电杆实现基于摩擦力的轴向移动。这里的轴向是指镜头载体200的筒状部210的轴线方向,即光学镜头700的光轴方向。本实施例中,第二适配结构232和第三适配结构233均用于安装附属引导装置320。第二适配结构232可以包括两个夹持臂,这两个夹持臂之间可以形成一个不封闭的孔状结构,导杆321穿过两个夹持臂之间的孔状结构。这样,第二适配结构232的移动方向大体上被限制在沿着导杆321移动的方向上,即第二适配结构232的移动方向被大致限定在所述的轴向移动的方向上。另一方面,本实施例中,镜头载体为塑料件,其平板部220的适配结构也是塑料件。由于第二适配结构232的孔状结构是不封闭的,因此这两个夹持臂可以具有一定的形变能力,这种设计可以避免导杆321与第二适配结构232的配合过紧而导致平板部220被卡死在导杆321上。进一步地,本实施例中,所述第三适配结构233的中央可以具有一定位孔。支撑座500可以具有一定位柱322,该定位柱322向上穿过所述的定位孔并与所述第三适配结构233活动连接。其中,所述定位孔的孔壁与定位柱322的外侧面之间可以设置滚珠,该滚珠可以具有多个并围绕在定位柱322的周围,以在径向上支撑所述定位孔的孔壁与所述定位柱322。这里径向是指定位柱322的径向,即垂直于所述定位柱322的轴线的方向。这种设计可以更好地提升镜头载体200移动的直线度,并且通过滚珠的径向支撑,可以减小镜头载体200的移动阻力。本实施例中,镜头载体200的平板部220设置了两种不同类型的适配结构来安装附属引导装置320,其中第二适配结构232成本较低,便于组装,可以设置在第一适配结构232的对角位置处。第三适配结构233可以设置在靠近压电驱动装置310的压电杆的位置处,以便更好地提升镜头载体200移动的直线度,减小镜头载体200的移动阻力。
进一步地,图31示出了本申请一个实施例中的压电驱动装置及其周边结构的局部放大示意图。参考图31,本申请的一个实施例中,压电驱动装置的驱动杆312的顶端可以设置一限位结构319以防止移动部的移动范围超出设计行程, 该限位结构319可以是橡胶圈。压电元件313可以通过导线511电连接至支撑座上表面的第一线路板510。
本申请的一些实施例中,提供了基于芯片端移动光学防抖的伸缩式摄像模组,该摄像模组中通过压电驱动装置驱动光学镜头伸出和缩回壳体,同时基于十字引导结构、滚珠以及电磁驱动装置实现感光芯片的横向双轴移动,以实现光学防抖,这种设计既可以使摄像模组的结构紧凑,又避免了镜头伸缩驱动装置与感光芯片驱动装置之间的电磁串扰的问题。
并且,本申请的一些实施例中,摄像模组的用于驱动光学镜头的伸缩式光学致动器和用于驱动感光芯片移动(即驱动芯片组合体移动)的两轴光学致动模块可以共用同一支撑座,从而减小摄像模组的整体高度。进一步地,所述支撑座上方布置具有磁轭的定位片,使得定位片可以向支撑座施加z轴方向的压力,这样支撑座和载体之间可以形成z轴方向的预压力,从而将滚珠夹持在中间。同时,定位片和布置在支撑座表面的第一线路板还有助于对支撑座的结构强度进行补强。支撑座上可以具有多个避让孔,磁体和线圈可以布置在所述避让孔中,光学致动模块的磁体和线圈不会额外占用摄像模组的高度方向上的空间,从而帮助减小摄像模组的高度。
本领域的技术人员应理解,上述描述及附图中所示的本发明的实施例只作为举例而并不限制本发明。本发明的目的已经完整并有效地实现。本发明的功能及结构原理已在实施例中展示和说明,在没有背离所述原理下,本发明的实施方式可以有任何变形或修改。
