本申请还提供一种电子设备，所述电子设备包括摄像头模组。
请参照图1和图2，本申请提供一种电子设备1，所述电子设备1包括设备本体20以及 摄像头模组10，所述摄像头模组10安装于所述设备本体20。
所述电子设备1可以是手机、平板电脑、笔记本电脑、超级移动个人计算机、可穿戴设备(如智能手表、手环、VR设备等)、电视机、车载设备、电子阅读器等。需说明的是，本申请实施例仅以电子设备1为手机进行示例性说明，但不应视作为是对本申请的限制。
其中，所述设备本体20是指电子设备1的主体部分，主体部分包括实现电子设备1主要功能的电子组件以及保护、承载这些电子组件的壳体。以手机为例，设备本体20可以包括显示屏21、中框22、电池盖23，显示屏21和电池盖23均连接于中框22，且设置于中框22的相背两侧。
根据实际需求，摄像头模组10可以显露于电子设备1的任意一侧，本申请对此不作限定。以手机为例，所述摄像头模组10可以显露于手机的正面、背面、侧面。其中，所谓正面是指手机具备显示屏21的一侧；所谓背面是指手机具备电池盖23的一侧；所谓侧面是指手机的中框22的环周侧。可以理解的是，电子设备1的类型不同，其正面、背面、侧面等称呼的定义可能不同，对于其它类型的电子设备1在此不一一详述。
可以理解的是，用户在使用电子设备进行拍摄时，难免会因为自身或外部因素出现手抖的情况，而抖动将导致电子设备上的摄像头模组相对于被拍摄物体移动，进而造成拍摄画面模糊，为了克服该问题，防抖技术应运而生。目前，厂商大多采用OIS光学防抖，在此类摄像头模组中设有马达，该马达可以驱动镜头垂直光轴G运动，以进行位移补偿实现防抖。一般来讲，镜头在X轴方向和Y轴方向上都具有移动自由度，使得镜头能够在X/Y方向进行位移补偿，其中，X/Y轴垂直于光轴G。
相关技术中，一个马达只能驱动镜头往一个方向上运动，因而需要设置两个马达，其中的一个马达驱动镜头沿X轴方向运动，另一个马达驱动镜头沿Y轴方向运动。此外，每个马达需要固定承载，因而需要设置两个独立的承载座来分别承载两个马达。然而，该结构形式将导致摄像头模组的体积较大。
基于此，本申请希望提供一种能够解决但不仅限于上述技术问题的摄像头模组，其详细内容将在后续实施例中得以阐述。
请参照图3至图6，本申请提供一种摄像头模组10，所述摄像头模组10包括：收容组件110、镜头组件120、第一压电模块130。所述收容组件110包括基座112和保护壳111，所述保护壳111和所述基座112共同构成收容空间X1。所述镜头组件120至少部分位于所述收容空间X1内且活动连接于所述基座112。所述第一压电模块130位于所述收容空间X1内，所述第一压电模块130的一端连接于所述收容组件110，所述第一压电模块130的另一端活动抵接于所述镜头组件120。所述第一压电模块130用于在通电时驱动所述镜头组件120沿所述基座112的表面往第一方向D1或第二方向D2运动。其中，所述第一方向D1和所述第二方向D2不平行且均垂直于光轴G。
其中，基座112主要用于对位于收容空间X1内的零部件起到承载作用。保护壳111主要用于对位于收容空间X1内的零部件起到保护作用。基座112和保护壳111两者连接在一起，从而将镜头组件120等限定在收容空间X1内。
其中，第一压电模块130也可以称之为定子、或马达、或驱动器、或致动器。第一压电模块130至少包含压电材料，当在压电材料的极化方向上施加电场时，压电材料将会发生变形，当电场去掉后，压电材料的变形随之消失。根据该特性，可通过电控来控制压电材料变形，使其产生高频振动，从而可实现驱动功能。
第一压电模块130的一端连接于收容组件110，从而实现将第一压电模块130固定或限位。第一压电模块130可以连接于保护壳111，也可以连接于基座112，在此不做限定，本申请仅以第一压电模块130连接于保护壳111进行示例性说明。
第一压电模块130的另一端与镜头组件120为抵接关系，抵接则意味着两者之间存在压力。当第一压电模块130振动时，第一压电模块130与镜头组件120两者之间将产生摩擦。由于镜头组件120活动连接于基座112，因而在第一压电模块130的摩擦作用下，镜头组件120将相对基座112运动，摄像头模组10的防抖功能得以实现。
进一步的，第一压电模块130在第一方向D1和第二方向D2上均能够产生变形，即第一压电模块130具有双自由度，因而第一压电模块130能够在第一方向D1和第二方向D2上向镜头组件120提供驱动力，该驱动力体现为摩擦力。当第一压电模块130向镜头组件120施加的摩擦力的方向为第一方向D1时，镜头1211则往第一方向D1运动，当第一压电模块130向镜头组件120施加的摩擦力的方向为第二方向D2时，镜头1211则往第二方向D2运动。
可以理解的是，由于镜头组件120可以在第一方向D1和第二方向D2运动，因此镜头组件120可以到达同一平面内的任意位置，从而确保使得摄像头模组10具有较好的防抖效果。
可选的，第一方向D1和第二方向D2相互垂直，如此更有利于开发人员根据镜头组件120的运动路径设计控制第一压电模块130的驱动程序。
需说明的是，在图4中，D1+代表第一方向的正方向，D1-代表第一方向的负方向，即D1+和D1-平行且相反。D2+代表第二方向的正方向，D2-代表第二方向的负方向，即D2+和D2-平行且相反。
综上，本申请提供的摄像头模组10中，通过将第一压电模块130的一端连接于收容组件110，将另一端抵接于镜头组件120，从而使得第一压电模块130可以通过摩擦带动镜头组件120运动。由于第一压电模块130能够在第一方向D1和第二方向D2两个方向上驱动镜头组件120运动，因而第一压电模块130相当于集成了两个单自由度的马达，换而言之，第一压电模块130为双自由度。相对于使用两个单自由度马达来驱动镜头组件120往两个不同的方向运动的结构形式而言，采用双自由度的第一压电模块130则意味着减少了马达的数量，从而也就减少了承载马达所需的零部件。因此，本申请提供的摄像头模组10可以减小摄像头模组10的体积。
可选的，所述第一压电模块130沿所述光轴G方向抵接于镜头组件120，也就是说，第一压电模块130抵接于镜头组件120的方向平行于光轴G方向，因此，第一压电模块130向镜头组件120施加的摩擦力的方向垂直于光轴G方向。如此设置，使得第一压电模块130向镜头组件120施加的摩擦力全部转化为驱动镜头组件120位移的驱动力，从而可以减少第一压电模块130的电量消耗，也可以确保较小体积的第一压电模块130也能提供足够的驱动力。
请参照图7至图8，所述第一压电模块130包括承载件131、第一压电体132、第一摩擦件133。所述第一摩擦件133连接于所述承载件131的一端且所述第一摩擦件133活动抵接于所述镜头组件120。所述承载件131上远离所述第一摩擦件133的一端连接于所述收容组件110。所述第一压电体132连接于所述承载件131。所述第一压电体132用于在通电时通过所述承载件131带动所述第一摩擦件133运动，以使所述第一摩擦件133带动所述镜头组件120移动。
其中，第一压电体132为压电材料，压电材料可选用锆钛酸铅(PZT)基压电陶瓷、铌酸钾钠(KNN)基压电陶瓷、钛酸钡(BT)基压电陶瓷、铌镁酸铅-铌铟酸铅(PMN-PT)基压电单晶、织构陶瓷等。
其中，第一摩擦件133也可称之为摩擦头。第一摩擦件133的形状可采用圆柱形，半圆柱形状，球形、三角锥形或其他一些不规则形状设计。第一摩擦件133的数量可以采用一个，也可以采用多个。特别的，第一摩擦件133表面可以做倒角或倒圆角设计。其材料可选用氧化铝(Al2O3)、氧化硅(SiO2)、氧化锆(ZrO2)或碳纤维、聚酯纤维、铝、铁、铜、不锈钢等耐磨材料，这样既能保证第一压电模块130的驱动力能良好的传递给镜头组件120，同时也能防止长时间工作下的磨损，保持配合精度。
其中，承载件131可以为圆柱体、长方体、正方体等，本申请以长方体进行示例性说明。承载件131为承载第一压电体132和第一摩擦件133的载体。承载件131的材料可以为金属，如铜、铁、铝等常用金属，一些情况下也可采用非金属材料，如亚克力或其他高强度材料。
承载件131、第一压电体132、第一摩擦件133连接为一体。当第一压电体132通电振动时，承载件131将振动传递给第一摩擦件133。第一摩擦件133在垂直于光轴G的方向上形成一定的振动幅度，从而使得第一摩擦件133和镜头组件120之间产生摩擦，摩擦力的方向垂直于光轴G的方向。虽然第一压电体132每次振动时的形变量较小，对应的镜头组件120 的位移量也较小，但是，在第一压电体132的高频振动下，镜头组件120可在较短时间内经过若干次位移累积获得较大的位移量。
需说明的是，第一压电体132包含多个子压电体(数量大于或等于两个)，多个子压电体均连接于承载件131。当子压电体产生形变时，承载件131相应产生形变，进而使得第一摩擦件133运动。所有子压电体中的部分压电体用于驱动镜头组件120往第一方向D1运动，另一部分子压电体用于驱动镜头组件120往第二方向D2运动。可以理解的是，将多个子压电体都集中连接在同一个承载件131上，从而避免了多个子压电体需要多个零部件来承载的技术问题。因此，将多个子压电体集中在承载件131的设置形式可以减小摄像头模组10的体积。
请参照图7和图8，在一种实施方式中，所述第一压电模块130包括第一子压电体1321、第二子压电体1322、第三子压电体1323、第四子压电体1324四个子压电体。承载件131具有依次弯折连接的第一侧面M1、第二侧面M2、第三侧面M3、第四侧面M4，其中，第一侧面M1和第三侧面M3相背设置，第二侧面M2和第四侧面M4相背设置。第一子压电体1321连接于第一侧面M1，第二子压电体1322连接于第二侧面M2，第三子压电体1323连接于第三侧面M3，第四子压电体1324连接于第四侧面M4。所述第一子压电体1321和所述第三子压电体1323用于共同驱动所述镜头组件120往第一方向D1运动。所述第二子压电体1322和所述第四子压电体1324用于共同驱动所述镜头组件120往第二方向D2运动。需说明的是，在本实施方式中，第一子压电体1321、第二子压电体1322、第三子压电体1323、第四子压电体1324也可以同时工作以驱动镜头组件120往第一方向D1(或第二方向D2)运动，例如，通过向不同的子压电体施加不同相位的驱动信号以激发产生不同的模态，从而使第一摩擦件133的运动为多模态耦合的复合运动。其中，第一方向D1为第一侧面M1与第三侧面M3的相对方向。第二方向D2为第二侧面M2与第四侧面M4的相对方向。
在另一种实施方式中，所述第一压电模块130包括第一子压电体1321、第二子压电体1322、第三子压电体1323三个子压电体。承载件131具有依次弯折连接的第一侧面M1、第二侧面M2、第三侧面M3，其中，第一侧面M1和第三侧面M3相背设置。第一子压电体1321连接于第一侧面M1，第二子压电体1322连接于第二侧面M2，第三子压电体1323连接于第三侧面M3，换而言之，所述第三子压电体1323设置于所述承载件131背离所述第一子压电体1321的一侧。所述第一子压电体1321和所述第三子压电体1323用于共同驱动所述镜头组件120往第一方向D1运动，可以理解的是，第一子压电体1321和第三子压电体1323共同工作可以在第一方向D1上向镜头组件120提供更大的驱动力。
在又一种实施方式中，所述第一压电模块130包括第一子压电体1321、第二子压电体1322、第四子压电体1324三个子压电体。承载件131具有依次弯折连接的第一侧面M1、第二侧面M2、第四侧面M4，其中，第二侧面M2和第四侧面M4相背设置。第一子压电体1321连接于第一侧面M1，第二子压电体1322连接于第二侧面M2，第四子压电体1324连接于第四侧面M4，换而言之，所述第四子压电体1324设置于所述承载件131背离所述第二子压电体1322的一侧。所述第二子压电体1322和所述第四子压电体1324用于共同驱动所述镜头组件120往第二方向D2运动，可以理解的是，第二子压电体1322和第四子压电体1324共同工作可以在第二方向D2上向镜头组件120提供更大的驱动力。
在又一种实施方式中，所述第一压电体132包括第一子压电体1321、第二子压电体1322两个子压电体。承载件131具有第一侧面M1和第二侧面M2，第一侧面M1和第二侧面M2弯折连接。第一子压电体1321连接于第一侧面M1，第二子压电体1322连接于第二侧面M2，也就是说，所述第一子压电体1321和所述第二子压电体1322均连接于所述承载件131且沿所述承载件131的周向布置。其中，所述第一子压电体1321用于驱动所述镜头组件120往所述第一方向D1运动，即当第一子压电体1321通电产生形变时，第一摩擦件133则带动镜头组件120在第一方向D1上运动。所述第二子压电体1322用于驱动所述镜头组件120往所述第二方向D2运动，即当第二子压电体1322通电产生形变时，第一摩擦件133则带动镜头组件120在第二方向D2上运动。
可选的，承载件131采用导电材料制成，这样可以使得承载件131同时电连接于上述各个子压电体，从而可以使用一条导线连接于承载件131就实现了连接四个子压电体，可以理解的是，这样可以减少连接于子压电体导线的数量，优化了导线布局。
在以上各实施方式中，承载件131为长方体，也就是说，第一侧面M1和第二侧面M2相互垂直，第三侧面M3平行于第一侧面M1，第四侧面M4平行于第二侧面M2。如此设置，从而可以确保第一压电模块130向镜头组件120在第一方向D1和第二方向D2分别提供的驱动力相互垂直，并且还能够提高摄像头模组10的防抖效果。具体来讲，相关技术中，摄像头模组中包含独立第一马达和第二马达，第一马达用于驱动镜头往第一方向运动，第二马达用于驱动镜头往第二方向运动，从而在第一方向和第二方向进行位移补偿以实现防抖。由于第一方向和第二方向需要相互垂直，因而第一马达和第二马达需要面向于镜头的不同侧面，且第一马达、镜头、第二马达三者的连线构成直角，以使第一马达和第二马达向镜头提供的驱动力的方向相互垂直。然而，由于第一马达和第二马达面向于镜头的不同侧面，导致两者间隔较远，再加上装配、加工等误差的存在，在实际产品中，第一马达和第二马达难以刚好安装在理论位置上，换而言之，第一马达和第二马达向镜头提供的驱动力的方向难以做到相互垂直，从而造成镜头的位移补偿精度不高，防抖效果不佳。相较于相关技术中将第一马达和第二马达设置在理论位置而言，在本申请中，承载件131的形状较为容易设置为长方体，从而能够确保第一压电模块130向镜头组件120在第一方向D1和第二方向D2分别提供的驱动力相互垂直，因此，本申请提供的摄像头模组10的结构形式可以提升防抖效果。
进一步的，由于第一摩擦件133的运动需要通过承载件131变形振动来实现，若承载件131的产生形变的能力差，则会导致承载件131的振幅较小，第一摩擦件133从而不能很好的驱动镜头组件120，此时只能将各个子压电体做的更大，才能使承载件131产生更大的振幅，然而，子压电体的体积增大后会导致摄像头模组10的体积增大。
请参照图7，所述承载件131的内部开设至少一个腔体X2，即承载件131的内部设有空腔。在本实施例中，承载件131设置腔体X2后，从而更容易产生形变，进而有利于第一压电模块130驱动镜头组件120运动。具体来讲，子压电体在工作时，是通过承载件131来带动第一摩擦件133，也就是说，承载件131将跟随子压电体的变形而变形。在承载件131上设置腔体X2后，承载件131的刚度减小，形变能力增强，从而可以确保承载件131具有较大的振动振幅，这意味着在单位时间内第一摩擦件133可以驱动镜头组件120运动较大的位移，使得镜头组件120可以更快速的运动到目标位置。
其中，腔体X2的延伸方向可以平行于光轴G方向。腔体X2的延伸方向也可以垂直于光轴G方向，例如，腔体X2的延伸方向为第一侧面M1和第三侧面M3的相对方向。当然，腔体X2的延伸方向也可以是其他可行的实施方式，在此不做限定。腔体X2可以完全贯穿承载件131，例如，腔体X2同时贯穿第一侧面M1和第二侧面M2。腔体X2也可以未贯穿承载件131。
请参照图9、图10和图11，所述镜头组件120包括支撑座122和镜头单元121，所述支撑座122设置于所述收容空间X1内，所述镜头单元121承载于所述支撑座122。所述支撑座122包括底盖部1221和环绕部1222，所述底盖部1221与所述基座112相对设置且活动连接于所述基座112，所述环绕部1222弯折连接于所述底盖部1221的周缘，且所述环绕部1222往背离所述基座112的方向凸出于底盖部1221。所述镜头单元121可以承载于底盖部1221上，也可以承载于环绕部1222上。
请参照图9、图12和图13，保护壳111和基座112都设有透光孔X7，透光孔X7贯穿保护壳111和基座112，透光孔X7用于透过光线，镜头单元121正对透光孔X7设置。所述保护壳111包括顶盖部1113和环周部1114，所述顶盖部1113位于所述底盖部1221背离所述基座112的一侧，所述环周部1114弯折连接于顶盖部1113，且所述环周部1114往靠近所述基座112的方向凸出于顶盖部1113。所述环周部1114远离所述顶盖部1113的一端连接于基座112，从而将镜头组件120等限定在收容空间X1内。所述第一压电模块130的一端连接于所述顶盖部1113，所述第一压电模块130的另一端活动抵接于所述底盖部1221，也就是说，当 所述第一压电模块130通电振动时，第一压电模块130与支撑座122的底盖部1221产生摩擦，从而驱动支撑座122相对基座112运动，支撑座122进而带动镜头单元121运动，以实现位移补偿。
请参照图14，第一压电模块130与保护壳111的顶盖部1113的连接形式可以是固定连接，例如，第一压电模块130通过点胶、焊接、铆接等方式连接于顶盖部1113。顶盖部1113面向基座112的一侧可以设置定位槽X6，第一压电模块130的承载件131至少部分位于定位槽X6内，设置定位槽X6的目的在于快速确定顶盖部1113与第一压电模块130的连接位置，从而可以提高装配速度。可以理解的是，当第一压电模块130与顶盖部1113为固定连接时，第一压电模块130与支撑座122的抵接效果通过顶盖部1113实现，即顶盖部1113压迫第一压电模块130抵接于支撑座122。
请参照图15，支撑座122的底盖部1221背离基座112的一侧可以设置第一摩擦片123，第一摩擦片123可以采用内嵌的方式嵌入于底盖部1221，第一摩擦片123也可以采用粘接的方式与底盖部1221结合。第一摩擦片123的材料可选用氧化铝(Al2O3)、氧化硅(SiO2)、氧化锆(ZrO2)或碳纤维、聚酯纤维、铝、铁、铜、不锈钢等耐磨材料。
请参照图10、图11和图16，所述镜头组件120包括支撑座122和镜头单元121，所述镜头单元121承载于所述支撑座122。所述支撑座122包括底盖部1221和环绕部1222，所述底盖部1221与所述基座112相对设置且活动连接于所述基座112，所述环绕部1222弯折连接于所述底盖部1221的周缘，且所述环绕部1222往背离所述基座112的方向凸出于底盖部1221。所述环绕部1222环绕所述镜头单元121的外周且与所述镜头单元121间隔设置。所述第一压电模块130设置于所述镜头单元121和所述环绕部1222之间，且所述第一压电模块130间隔于所述镜头单元121和所述环绕部1222。由于第一压电模块130在工作时通过产生形变来实现振动，将第一压电模块130间隔的设置在镜头单元121和环绕部1222之间，从而可以在第一压电模块130的周围保留足够的形变空间，以使得第一压电模块130在振动时不会干涉到镜头单元121和环绕部1222，确保第一压电单元具有较大的振幅。
请参照图10、图11和图16，所述镜头单元121包括镜头1211和镜头载体1212，所述镜头1211承载于所述镜头载体1212，所述镜头载体1212承载于所述支撑座122。所述镜头载体1212具有避让空间X3，所述避让空间X3自所述镜头载体1212的外侧面往所述镜头1211的所在方向凹陷，所述第一压电模块130设置于所述避让空间X3内。其中，镜头1211和镜头载体1212可以但不仅限于通过螺纹、卡扣或点胶的方式进行连接。镜头载体1212面向于支撑座122的环绕部1222的外侧设有避让空间X3，该避让空间X3相当于镜头载体1212侧壁上的凹槽，将第一压电模块130设置在避让空间X3内则可以避免支撑座122的体积过大，反之，镜头组件120的体积可以做的更小，从而减小摄像头模组10的整体体积。其中，镜头1211包括透镜组和镜筒，透镜组设置在镜筒内，镜筒连接于镜头载体1212，透镜组包含多枚镜片，镜片的数量可以但不仅限于为2枚、3枚、4枚、5枚、6枚等。
请参照图17，可选的，所述保护壳111包括第一壳体1111，所述第一壳体1111包括第一顶盖部1111a和第一环周部1111b。所第一顶盖部1111a面向于所述基座112，所述第一环周部1111b弯折连接于所第一顶盖部1111a的周缘。所第一顶盖部1111a、所述第一环周部1111b、所述基座112共同围设成收容空间X1，且所述第一环周部1111b远离所第一顶盖部1111a的一端连接于所述基座112。其中，第一环周部1111b与底座的连接方式可以但不仅限于为点胶、焊接等。
请参照图17，可选的，所述保护壳111还可以包括第二壳体1112，所述第二壳体1112位于所述收容空间X1内，所述第二壳体1112包括第二顶盖部1112a，所述第二顶盖部1112a与所第一顶盖部1111a相对设置且所述第二顶盖部1112a连接于所述第一压电模块130。
请参照图18，可选的，所述第二壳体1112还可以包括第二环周部1112b，所述第二环周部1112b弯折连接于所述第二顶盖部1112a的周缘，所述第二环周部1112b环绕于所述支撑座122的外周，且位于所述第一环周部1111b和所述支撑座122之间。
具体来讲，保护壳111可以同时包含第一壳体1111和第二壳体1112，这样可以增大保护 壳111的整体强度，更有利于保护收容空间X1内的器件。保护壳111也可以仅包含第一壳体1111，这样有利于减小装配难度，降低成本等。进一步的，第二壳体1112可以仅包含第二顶盖部1112a，第二顶盖部1112a可以通过粘接等手段直接连接在第一顶盖部1111a上，此结构形式中，第一压电模块130抵接于第二顶盖部1112a，可以理解的是，设置第二顶盖部1112a后，可以避免由于第一顶盖部1111a强度较小而不能向第一压电模块130提供足够大预紧力的问题。进一步的，第二壳体1112还可以包含第二环周部1112b，设置第二环周部1112b可以在保护壳111的周向方向上提升强度，以避免被外部环境破坏。
请参照图9和图17，所述基座112包括层叠设置的第一基座1121和第二基座1122，所述第一基座1121与所述保护壳111共同构成所述收容空间X1。所述第二基座1122设置于所述第一基座1121背离所述支撑座122的一侧，所述第二基座1122用于承载所述滤光片140。所述第一基座1121和所述第二基座1122为分体式结构或一体式结构。其中，所谓的一体式结构是指第一基座1121和第二基座1122为不可拆分的整体。所谓分体式结构是指第一基座1121和第二基座1122为两个独立的整体。
请参照图9，所述摄像头模组10还包括滤光片140，所述滤光片140承载于所述基座112，所述滤光片140与所述镜头组件120的镜头1211相对设置。摄像头模组10还包括感光组件180，感光组件180设置于滤光片140背离镜头1211的一侧。感光组件180包括感光元件181和电路板182，感光元件181电连接电路板182，且感光元件181位于电路板182靠近滤光片140的一侧。
其中，镜头1211用于收集被摄景物的光线，并将光线聚焦于感光元件181。滤光片140用于消除不必要的光线，以提高有效分辨率和彩色还原性。滤光片140可以但不仅限于为红外滤光片140。感光元件181也称为感光芯片或图像传感器或Sensor，其用于接收穿过滤光片140的光线，并将光信号转换为电信号。感光元件181可以是电荷耦合器件(Charge Coupled Device，CCD)，也可以是互补金属氧化物导体器件(Complementary Metal Oxide Semiconductor，CMOS)。
请参照图18，所述摄像头模组10还包括第一滚动体160，所述第一滚动体160设置于所述基座112和所述支撑座122之间。当所述第一压电模块130驱动所述支撑座122运动时，所述支撑座122带动所述第一滚动体160滚动。可以理解的是，当第一压电模块130通电时，由于支撑座122将相对基座112运动，若支撑座122与基座112直接接触，将会产生阻力较大的滑动摩擦，造成第一压电模块130需要提供较大的驱动力才能驱使支撑座122运动，这将导致耗电量的大大增加。而在支撑座122和基座112之间设置第一滚动体160后，则可以使支撑座122、第一滚动体160、基座112三者之间为滚动摩擦，这样既能减小第一压电模块130的电量消耗，又能使运动过程更顺畅。
进一步的，由于承载件131连接于保护壳111，因而承载件131在振动时将受到保护壳111的约束。若保护壳111的约束作用过强，则会导致承载件131的振幅较小，从而不能很好的驱动镜头组件120，此时只能将各个子压电体做的更大，才能提供较大的振幅，然而，子压电体的体积增大后会导致摄像头模组10的体积增大。
请参照图19和图20，可选的，所述保护壳111包括顶盖部1113、弹性件1115，所述顶盖部1113与所述基座112相对设置，所述弹性件1115连接于所述顶盖部1113，所述弹性件1115沿顶盖部1113朝向基座112的方向弹性抵接于所述第一压电模块130。其中，弹性件1115起到两方面的作用，一方面是：向第一压电模块130提供弹性约束，相较于将第一压电模块130直接固定连接于顶盖部1113而言，弹性约束则代表第一压电模块130受到的约束作用更小，第一压电模块130的振动范围则可以更大，振动范围大即意味着较大的振幅，从而可以将镜头组件120更快速的驱动到目标位置。另一方面是：由于所述弹性件1115沿顶盖部1113朝向基座112的方向弹性抵接于所述第一压电模块130，使得保护壳111可以通过弹性件1115使第一压电模块130和镜头组件120之间抵紧，以确保第一压电模块130与镜头组件120之间的预紧力达到预设值，从而确保第一压电模块130在通电时能够向镜头组件120提供足够的摩擦驱动力。其中，弹性件1115可以但不仅限于为弹簧、弹片等。
第一压电模块130与保护壳111的顶盖部1113的连接形式可以是弹性连接，下面介绍两种可行的实施方式。
请参照图19，在一种实施方式中，弹性件1115包括抵接部1115c、第一连接部1115a、第二连接部1115b，其中，第一连接部1115a和第二连接部1115b分别连接于抵接部1115c的相背两端，且第一连接部1115a和第二连接部1115b均连接于顶盖部1113，以实现将弹性件1115固定在顶盖部1113上。抵接部1115c背离顶盖部1113的一侧连接于第一压电模块130，且抵接部1115c与顶盖部1113间隔设置，抵接部1115c用于向第一压电模块130施加弹性力，以确保第一压电模块130与镜头组件120之间的预紧力达到预设值。可以理解的是，抵接部1115c与顶盖部1113间隔设置则意味着两者之间存在间隙空间，该间隙空间可以为抵接部1115c的弹性变形提供空间。
请参照图20，在另一种实施方式中，所述保护壳111还包括调节件1116，所述顶盖部1113具有安装孔X4，所述安装孔X4贯穿所述顶盖部1113。所述第一压电模块130至少部分位于所述安装孔X4内，所述调节件1116通过螺纹旋合于所述安装孔X4内。所述弹性件1115位于所述调节件1116和所述第一压电模块130之间，且所述弹性件1115的相背两端分别抵接于所述调节件1116和所述第一压电模块130。其中，安装孔X4具有内螺纹，调节件1116具有外螺纹，通过内外螺纹的配合，调节件1116可以改变旋入安装孔X4的深度。可以理解的是，当调节件1116伸入安装孔X4的深度越大时，弹性件1115进一步被压缩，第一压电模块130与镜头组件120之间的预紧力越大。当调节件1116伸入安装孔X4的深度越小时，弹性件1115进一步被放松，第一压电模块130与镜头组件120之间的预紧力越小。因此，该结构形式使得第一压电模块130与镜头组件120之间预紧力可以实现调节，从而更容易将预紧力调节到所需的值。
请参照图9和图21，所述镜头组件120包括支撑座122和镜头单元121，所述镜头单元121承载于所述支撑座122。所述支撑座122包括底盖部1221和环绕部1222，所述底盖部1221与所述基座112相对设置且活动连接于所述基座112，所述环绕部1222弯折连接于所述底盖部1221的周缘且环绕所述镜头单元121设置。所述摄像头模组10还包括第二压电模块150，所述第二压电模块150承载于所述环绕部1222且活动抵接于所述镜头单元121的外侧壁。所述第二压电模块150用于在通电时驱动所述镜头单元121沿光轴G方向运动。也就是说，第二压电模块150用于驱动镜头单元121运动到目标位置，以实现对焦。所述第一压电模块130和所述第二压电模块150呈对角设置。所述环绕部1222设有容纳空间X7，所述第二压电模块150设置在容纳空间X7内。第二压电模块150也可以称之为定子、或马达、或驱动器、或致动器。第二压电模块150至少包含压电材料，当在压电材料的极化方向上施加电场时，压电材料将会发生变形，当电场去掉后，压电材料的变形随之消失。根据该特性，可通过电控来控制压电材料变形，使其产生高频振动，从而可实现驱动功能。
请参照图22和图23，所述第一压电模块130包括预紧件151、第二压电体152、第二摩擦件153。所述第二摩擦件153设置于所述第二压电体152面向于所述镜头单元121的一侧。所述预紧件151连接于所述第二压电体152且承载于所述环绕部1222。所述第二压电体152在所述预紧件151的作用下驱使所述第二摩擦件153抵接于所述镜头单元121的外侧壁。所述第二压电体152用于在通电时驱动所述第二摩擦件153驱动所述镜头单元121沿所述光轴G方向运动。其中，关于第二压电体152、第二摩擦件153的介绍请参照前面实施例中第一压电体132、第一摩擦件133的描述，在此不再赘述。
其中，预紧件151用于在第一压电模块130朝向镜头单元121的方向上向第二压电体152施加作用力，以使得第二摩擦件153能够压紧镜头单元121的外侧壁，且第二摩擦件153和镜头单元121之间的预紧力达到预设值。
可选的，预紧件151对第二压电体152的约束作用为弹性约束。所谓的弹性约束是指预紧件151会因第二压电体152的振动而产生相应的弹性形变。弹性约束可以使第二压电体152具有更大的振动范围，即振幅更大，换而言之，较小提交的第二压电体152都可以具有较大的振幅，从而可以将第二压电体152的体积设计的更小，进而减小摄像头模组10的提交。其 中，预紧件151可以但不仅限于为弹片。
请参照图22和图23，所述预紧件151上设有开口X5，所述开口X5为通孔或凹槽。开口X5的形状可以但不仅限于为圆形、矩形、椭圆形等。不管设置凹槽还是通孔，预紧件151的刚度都会减小，从而更容易发生形变。
第二压电体152在工作时激发至少一个模态。其中，至少一个模态是指模态的数量为一个或多个(所谓多个是指数量大于或等于两个)。当模态的数量为一个时，第二压电体152依靠一个模态产生微幅振动和驱动力，然后通过第二摩擦件153将多次累积的微幅振动转化为镜头单元121的宏观直线运动，从而实现驱动功能。可以理解的是，一个模态所对应的驱动控制方式更简单，从而可减小设计难度。
当模态的数量为多个时，第二压电体152可以在多个模态的耦合下进行工作。具体而言，在向第二压电体152施加一定频率的交流电信号后，第二压电体152同时激发出多个模态。第二压电体152依靠多个模态耦合产生微幅振动和驱动力，然后通过第二摩擦件153将多次累积的微幅振动转化为镜头单元121的宏观直线运动，从而实现驱动功能。可以理解的是，第二压电体152激发多个模态，且多个模态耦合，相较于第二压电体152只激发一个模态而言，多个模态耦合后第二压电体152产生的能量密度更大，即驱动力更大，在相同驱动力的条件下，多个模态耦合的第二压电体152的体积可以做的更小。其中，模态耦合可以但不仅限于为横向伸缩模态(如：L1模态)和纵向弯曲模态(如：B2模态)相耦合的L1-B2工作模态等。
请参照图21，所述摄像头模组10还包括第二滚动体170，所述第二滚动体170活动抵接于所述环绕部1222和所述镜头单元121之间，当所述镜头单元121沿所述光轴G方向运动时，所述镜头单元121带动所述第二滚动体170滚动。第二滚动体170可以为圆柱状，也可以为球状。
请参照图24，镜头单元121的镜头载体1212的外侧壁可以设置第二摩擦片125，第二摩擦片125可以采用内嵌的方式嵌入于镜头载体1212，第二摩擦片125也可以采用粘接的方式与镜头载体1212结合。第二摩擦片125的材料可选用氧化铝(Al2O3)、氧化硅(SiO2)、氧化锆(ZrO2)或碳纤维、聚酯纤维、铝、铁、铜、不锈钢等耐磨材料。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型，这些改进和润饰也视为本申请的保护范围。
