下面将详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合图1至图8，描述根据本申请实施例的电子设备40。电子设备40包括摄像头模组30和防抖壳组10，防抖壳组10设有适于安装摄像头模组30的安装空间110。具体地，防抖壳组10中部形成有安装空间110，用于放置摄像头模组30，且安装好的摄像头模组30与防抖壳组10紧密连接，安装空间110与摄像头模组30的形状适配，例如摄像头模组30底部可以为方形，而对应的安装空间110对应为矩形设置，安装空间110也可以为圆形或者其他形状，在此不做限定。
请参照图2至图4，防抖壳组10包括第一压电陶瓷驱动单元120和第二压电陶瓷驱动单元130，第一压电陶瓷驱动单元120用于驱动摄像头模组30在第一方向上进行转动防抖，第二压电陶瓷驱动单元130用于驱动摄像头模组30在第二方向上进行转动防抖。其中，第一方向和第二方向夹角设置。第一压电陶瓷驱动单元120和第二压电陶瓷驱动单元130中的至少一者能够驱动摄像头模组30进行转动防抖，例如可以采用第一压电陶瓷驱动单元120驱动摄像头模组30在第一方向上进行转动防抖，或者采用第二压电陶瓷驱动单元130驱动摄像头模组30在第二方向上进行转动防抖。例如可以参照图4，第一方向对应X方向，第二方向对应Y方向。
也即，当第一压电陶瓷驱动单元120处于运行状态时，第一压电陶瓷驱动单元120可以带动摄像头模组30在第一方向上进行转动防抖，因为摄像头模组30与防抖壳组10紧密连接，由此第一压电陶瓷驱动单元120可以同步驱动摄像头模组30在第一方向上转动；当第二压电陶瓷驱动单元130处于运行状态时，第二压电陶瓷驱动单元130可以带动摄像头模组30在第二方向上进行转动防抖。或者也可以使得第一压电陶瓷驱动单元120和第二压电陶瓷驱动单元130同时运行，以实现摄像头模组30在两个方向上进行转动防抖。
例如，在可选的实施例中，第一压电陶瓷驱动单元120处于通电状态，而第二压电陶瓷驱动单元130处于断电状态，第一压电陶瓷驱动单元120作为驱动件带动摄像头模组30在一方向进行转动防抖。在另一可选的实施例中，第二压电陶瓷驱动单元130处于通电状态而第一压电陶瓷驱动单元120处于断电状态，第二压电陶瓷驱动单元130作为驱动件带动摄像头模组30在第二方向转动防抖。在又一可选的实施例中，当第一压电陶瓷驱动单元120和第二压电陶瓷驱动单元130同时处于通电状态，进而可以对摄像头模组30在两个方向分别进行转动防抖。换句话说，对于第一压电陶瓷驱动单元120和第二压电陶瓷驱动单元130的通断电状态可以根据具体摄像头模组30的偏移角度进行控制。
请参照图4至图8，在本申请可选的实施例中，第一压电陶瓷驱动单元120和第二压电陶瓷驱动单元130分别包括线路板导线210、压电陶瓷片220、振动舌片230以及动子240。
具体来说，线路板导线210用于与摄像头模组30上设置的控制板320(可参照图4)相连接，压电陶瓷片220用于与线路板导线210相连接，振动舌片230与压电陶瓷片220相连接并设于远离线路板导线210的一侧。动子240与振动舌片230相连接并设于远离压电陶瓷片220的一侧。压电陶瓷片220内设有套筒250以及配合轴承260，配合轴承260套设于套筒250内并且与套筒250转动连接，配合轴承260的一端与动子240固定连接，动子240与防抖壳组10相连接。振动舌片230和动子240之间还设有密封垫圈280，密封垫圈280的一端与动子240之间紧密连接。
请继续参照图4至图7，在本申请的一些实施例中，防抖壳组10包括第一防抖壳组140和第二防抖壳组150，第二防抖壳组150套设于第一防抖壳组140外，第一防抖壳组140与第二防抖壳组150之间间隔设置，第一压电陶瓷驱动单元120位于第一防抖壳组140和第二防抖壳组150之间。第二防抖壳组150外还设有外框160，第二防抖壳组150和外框160之间间隔设置，第二压电陶瓷驱动单元130位于第二防抖壳组150和外框160之间。第二防抖壳组150与第一防抖壳组140和外框160之间转动连接。也即，第一压电陶瓷驱动单元120设于第一防抖壳组140并能够驱动第一防抖壳组140在第一方向上进行防抖。第二压电陶瓷单元设于第二防抖壳组150并能够驱动第二防抖壳组150在第二方向上转动防抖。
以下先以第一压电陶瓷驱动单元120进行说明，第一压电陶瓷驱动单元120中的动子240与第一防抖壳组140相连接，通过线路板导线210给压电陶瓷片220的正极通电，压电陶瓷片220产生振动，振动舌片230与压电陶瓷片220紧密连接，振动舌片230振动带动配合轴承260沿套筒250的轴线方向转动，也即配合轴承260会在振动舌片230往复运动时相对套筒250发生转动，进而带动动子240转动，动子240转动带动第一防抖壳 体410在第一方向转动。
同理，对于第二防抖壳组150，第二防抖壳组150中的动子240与第二防抖壳体410固定连接，线路板导线210给压电陶瓷片220的正极通电，压电陶瓷片220产生振动，振动舌片230与压电陶瓷片220往复运动过程中，配合轴承260会沿套筒250的轴线方向转动，进而带动与配合轴承260固定连接的动子240转动，动子240与第二防抖壳体410固定连接，由此便可以驱动第二防抖壳体410在第二方向上发生转动。压电陶瓷片220的通电，负极产生的转动效果与正极相反，也即可以对第一方向和第二方向的顺、逆时针方向转动进行调整，原理与上述一致，在此不做过多赘述。
在本申请可选的实施例中，配合轴承260外周侧设有螺旋滑道2610，配合轴承260与套筒250之间设有滚珠270，滚珠270与螺旋滑道2610相适配。套筒250套设于振动舌片230内腔，且与振动舌片230固定连接。配合轴承260套设于套筒250内，当振动舌片230振动状态下，会带动套筒250沿一方向进行振动，进而配合轴承260会相对套筒250发生转动，配合轴承260的一端与动子240固定连接，动子240与第一防抖壳体410和第二防抖壳体410固定连接，进而动子240转动便可以带动第一防抖壳体410或者第二防抖壳体410发生转动。
在本申请又一些实施例中，第一压电陶瓷驱动单元120也可以对第一防抖壳组140进行同一平面的直线驱动，例如配合轴承260与套筒250之间的相对运动可以为沿套筒250的轴线平移，进而驱动第一防抖壳组140在套筒250的轴线方向进行移动。第二压电陶瓷驱动单元130对于第二防抖壳组150的驱动与上述第一压电陶瓷驱动单元120对于第一防抖壳组140的驱动原理一致，在此不做赘述。也即第一压电陶瓷驱动单元120和第二压电陶瓷驱动单元130对于摄像头模组30的驱动也可以实现同一平面的X轴、Y轴的平移，也属于本申请的保护范围内，在此不做过多赘述。
在本申请进一步的实施例中，第一防抖壳组140和第二防抖壳组150上开设有安装槽190，动子240嵌设于安装槽190内。需要说明的是，动 子240可以粘设于安装槽190内，或者焊接至安装槽190内均可，在此不做限定。配合轴承260与动子240之间可以通过焊接固定连接，也可以采用卡扣或者粘接进行连接，具体的连接方式，上述只是例举并非限定，在此不做过多赘述。
请继续参照图4，在本申请的具体应用过程中，例如摄像头模组30的防抖包括X轴防抖和与X轴防抖垂直的Y轴防抖，也即用户在使用拍照功能时，需要在摄像头模组30的X轴和Y轴方向上进行防抖，Z轴属于摄像头模组30上下的驱动，相较于X轴和Y轴影响较小，在此不做过多说明。在本申请可选的实施例中，第一方向和第二方向垂直设置，对应X轴和Y轴垂直设置。也即第一压电陶瓷驱动单元120用于驱动摄像头模组30在X轴方向上转动防抖，第二压电陶瓷驱动单元130用于驱动摄像头模组30在Y轴方向上转动防抖，进而对于摄像头模组30在X轴和Y轴方向上的多角度的抖动，第一压电陶瓷驱动单元120和第二压电陶瓷驱动单元130均可以进行调整，以实现摄像头模组30多角度的防抖。
请参照图4至图7，在本申请的一些实施例中，第一防抖壳组140和第二防抖壳组150之间设有第一转动件170，第一转动件170设于第一防抖壳组140的一侧，第一压电陶瓷驱动单元120设于第一防抖壳组140的另一侧，而且第一防抖壳组140与第一转动件170转动连接。也即第一压电陶瓷驱动单元120通电时，第一压电陶瓷驱动单元120驱动第一防抖壳体410围绕第一转动件170转动，也即摄像头模组30可以围绕第一转动件170在第一方向上转动。
进一步地，对于第二防抖壳组150，第二防抖壳组150与外框160之间设有第二转动件180，第二转动件180设于第二防抖壳组150的一侧，第二压电陶瓷驱动单元130设于第二防抖壳组150的另一侧，第二防抖壳组150与第二转动件180转动连接。同理，第二压电陶瓷驱动单元130处于通电状态时，第二压电陶瓷驱动单元130驱动第二防抖壳体410围绕第二转动件180转动。此时，摄像头模组30与第一防抖壳体410固定连接， 第一压电陶瓷驱动单元120处于断电状态，进而第一防抖壳组140和第二防抖壳组150之间固定连接。由此，第二压电陶瓷驱动单元130处于通电状态下，便可以带动摄像头模组30在第二方向上转动防抖。
进一步地，当第一压电陶瓷驱动单元120和第二压电陶瓷驱动单元130同时处于通电状态，则第一压电陶瓷驱动单元120可以带动第一防抖壳体410围绕第一转动件170转动，第二压电陶瓷驱动单元130可以带动第二防抖壳体410围绕第二转动件180转动，进而摄像头模组30可以同时对第一方向和第二方向上的偏移角度同时进行调整，以实现多角度防抖。
在本申请可选的实施例中，第一转动件170为第一安装轴承，第一安装轴承的一端与第一防抖壳体410固定连接，第一防抖壳组140上开设有第一安装孔1410，第一安装轴承与第一安装孔1410转动配合。第二转动件180为第二安装轴承，第二安装轴承的一端与外框160固定连接，第二防抖壳组150上设有第二安装孔1510，第二安装轴承与第二安装孔1510转动配合。在其他可行的实施例中，第一转动件170和第二转动件180也可以为其他可转动的圆柱形转动杆，也即可以使得第一防抖壳体410可以围绕第一转动件170转动或者第二防抖壳体410可以围绕第二转动件180转动即可，在此不做限定。
请继续参照图1和图2，在本申请的一些实施例中，防抖壳组10的外部还设有外壳340，用于套设于防抖壳组10，且外壳340上开设有限位孔3410，限位孔3410用于避让摄像头模组30。控制板320与线路板导线210相连接，进而可以将控制信号发送至线路板导线210以控制压电陶瓷片220的振动状态。需要说明的是，控制板320远离摄像头模组30一侧还设有基座1910，用于对控制板320进行支撑，进而提高控制板320的安装稳定性。当摄像头模组30需要在第一方向或者第二方向进行防抖时，控制板320发送信号至线路板导线210，进而驱动第一压电陶瓷驱动单元120或者第二压电陶瓷驱动单元130对摄像头模组30进行转动防抖。
请参照图8，壳体410上还设有控制单元420和陀螺仪430，控制单元 420与控制板320相连接，陀螺仪430用于获取摄像头模组30的角速度信息并传输至控制板320，控制板320基于角速度信息控制防抖壳组10对摄像头模组30进行转动防抖。作为在此使用的“电子设备40”(或简称为“终端”)包括，但不限于被设置成经由有线线路连接(如经由公共交换电话网络(PSTN)、数字用户线路(DSL)、数字电缆、直接电缆连接，以及/或另一数据连接/网络)和/或经由(例如，针对蜂窝网络、无线局域网(WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器，以及/或另一通信终端的)无线接口接收/发送通信信号的装置。被设置成通过无线接口通信的通信终端可以被称为“无线通信终端”、“无线终端”或“电子设备40”。电子设备40的示例包括，但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。手机即为配置有蜂窝通信模块的电子设备40，此处以手机作为图示，但并非对其进行限定。
