后壳可以是电子设备1的电池盖，它的材质可以是玻璃、金属和硬质塑料等，也可以由其它电致变色材料制成。其中，后壳具有一定的结构强度，主要用于保护电子设备1。相应地，中框的材质也可以是玻璃、金属和硬质塑料等。中框也具有一定的结构强度，主要用于支撑和固定拍摄装置20以及安装在中框和后壳之间的其他功能器件。例如电池、主板以及天线等。进一步地，由于中框和后壳一般会直接暴露于外界环境，中框和后壳的材质可以优选地具有一定的耐磨耐蚀防刮等性能，或者在中框和后壳的外表面(也即是电子设备1的外表面)涂布一层用于耐磨耐蚀防刮的功能材料。
显示屏30可以包括显示模组以及用于响应对显示模组进行触控操作的电路等。其中，显示屏30可以是使用OLED(Organic Light-Emitting Diode有机发光二极管)的屏幕进行图像显示，也可以是使用LCD(Liquid Crystal Display，液晶显示器)的屏幕进行图像显示。并且显示屏30在外形上可以是平板屏幕，也可以是双曲面屏幕，还可以是四曲面屏幕，本实施例对此不作限定。需要说明的是，对于手机而言，上述平板屏幕是指显示屏30在整体上呈平板状设置；上述双曲面屏幕是指显示屏30的左、右边缘区域呈弯曲状设置，其他区域依旧呈平板状设置，这样不仅能够减小显示屏30的黑边并增加显示屏30的可视区域，还能够增加电子设备1的外观美感及握持手感；上述四曲面屏幕是指显示屏30的上、下、左、右边缘区域均呈弯曲状设置，其他区域依旧呈平板状设置，这样不仅能够进一步减小显示屏30的黑边并增加显示屏30的可视区域，还能够进一步增加电子设备1的外观美感及握持手感。请参阅图2，图2为图1所示电子设备中拍摄装置的第一种结构框图。拍摄装 置20可以包括镜头100、感光元件200、支架300、防抖模组400和防抖机构500。

感光元件200具体可以是CCD(Charge Coupled Device，电荷耦合元件)这类影像传感器，也可以是CMOS(Complementary Metal Oxide Semiconductor，互补金属氧化物半导体)这类影像传感器。感光元件200可以在拍摄装置20的光轴方向(也即是镜头100光轴101方向，如图2中虚线所示)上与镜头100相对设置，主要用于接收来自镜头100采集的光线，并将光信号转化为电信号，以便于实现拍摄装置20的成像需求。防抖机构500设置在支架300的另一侧，感光元件200设置在防抖机构500上，通过防抖机构500可以驱动感光元件200移动以实现拍摄装置20的感光元件200防抖。
可以理解的是，防抖模组400和防抖机构500主要用于改善拍摄装置20因用户在使用过程中发生抖动而产生的成像效果，以使得感光元件200的成像效果能够满足用户的使用需求。本申请实施例的拍摄装置20既可以实现镜头100防抖，又可实现感光元件200防抖，即本申请实施例的拍摄装置20可以具有双防抖功能。
相关技术中，通常仅可以实现摄像头防抖或感光元件防抖等单一防抖功能，然而摄像头防抖或感光元件防抖等单一防抖结构受电子设备的结构空间限制所能实现的防抖角度有限，仅能实现小角度(诸如1°以内或1.5°以内)的光学防抖功能。本申请实施例的拍摄装置20可以同时实现镜头100防抖和感光元件200防抖，集成镜头100防抖功能以及感光元件200防抖功能，相对于相关技术可以实现更大角度的光学防抖，有效提升拍摄装置20的光学防抖效果。

在一些实施例中，为了提高感光元件移动控制的准确性，第一模组541可以包括第一元件5411、第二元件5412和第三元件5413，第一元件5411、第二元件5412和第三元件5413均可以为上述的霍尔传感器，第二模组542可以包括与第一元件5411相对设置的第四元件5421、与第二元件5412 相对设置的第五元件5422以及与所述第三元件相对设置的第六元件5423。第四元件5421、第五元件5422以及第六元件5423可以为如上所述的磁性件，第一元件5411用于检测第四元件5421的第一磁性信息，第二元件5412用于检测第五元件5422的第二磁性信息，第三元件5413用于检测第六元件5423的第三磁性信息，根据第一磁性信息、第二磁性信息以及第三磁性信息检测壳体510和底板520的相对移动量。

以第一元件5411、第二元件5412以及第三元件5413所在平面建立直角坐标系xOy，第二元件5412所在位置作为原点，当移动装置530带动底板520相对于壳体510移动时，通过第一元件5411检测第四元件5421的第一磁性信息、第二元件5412检测第五元件5422的第二磁性信息以及第三元件5413检测第六元件5423的第三磁性信息，对第一磁性信息、第二磁性信息以及第三磁性信息分析，可以得到壳体510和底板520的相对移动量，例如，通过分析第一磁性信息得到第一元件5411沿Y轴的正方向移动一个单位长度、分析第二磁性信息得到第二元件5412沿Y轴的正方向移动一个单位长度、分析第三磁性信息得到第三元件5413沿着Y轴的正方向移动的一个单位长度，则说明底板相对于壳体沿着Y轴正方向平移的一个单位长度，又例如，通过分析第一磁性信息得到第一元件5411沿X轴的正方向移动两个单位长度、分析第二磁性信息得到第二元件5412沿X轴的正方向移动两个单位长度、分析第三磁性信息得到第三元件5413沿着X轴的正方向移动的两个单位长度，则说明底板相对于壳体沿着X轴正方向平移的两个单位长度。又例如，通过分析第一磁性信息得到第一元件5412朝向与X轴正方向之间夹角为A°的方向偏移了a个单位长度；分析第二磁性信息得到第二元件5412朝向与Y轴正方向之间夹角为B°的方向偏移了b个单位；分析第三磁性信息得到第三元件5413朝向与Y轴负方向夹角为C°的方向偏移了c个单位，则说明底板相对于壳体沿着预设轴顺时针转动e°，其中转动角度可以通过分析第一磁性信息、第二磁性信息以及第三磁性信息得到。预设轴的位置可以通过分析第一元件、第二元件以及第三元件偏移角度和偏移长度确定出，预设轴也可以为根据实验数据设定的预设轴，预设轴可以为底板的中心位置，也可以为第一元件、第二元件以及第三元件之间形成的三角形的中心位置。
可以理解的是，由于感光元件200固定设置于底板520，底板520相对于壳体510的移动量相当于感光元件200的移动量，移动装置可以根据感光元件200的移动量实时控制感光元件的移动，请参阅图2至图8，图7为图5所示A部分的爆炸结构图。图8为图7所示驱动件和移动件的结构示意图。
移动装置530设置的记忆金属驱动模组包括移动件531和驱动件532，驱动件532可发生形变以带动移动件531移动，移动件531可带动底板520相对于壳体510移动。

示例性的，移动装置530设置的记忆金属驱动模组还包括固定弹片533，固定弹片533与壳体510固定连接，移动件531包括第一端部5315、第二端部5316、第三端部5317以及第四端部5318， 固定弹片533包括第五端部5331、第六端部5332、第七端部5333以及第八端部5334；第一形变件5321可以包括与第一端部5315固定连接的第一牵动端53211以及和第五端部5331固定连接的第一固定端53212；第二形变件5322包括与第二端部5316固定连接的第二牵动端53221以及和第六端部5332固定连接的第二固定端53222；第三形变件5323包括与第三端部5314固定连接的第三牵动端53231以及与第七端部5333固定连接的第三固定端53232，第四形变件5324包括与第四端部5318固定连接的第四牵动端53241以及和第八端部5334固定连接的第四固定端53242。第一形变件5321、第二形变件5322、第三形变件5323和第四形变件5324形变时，第一牵动端53211牵动移动件的第一端部5315，第二牵动端53221牵动移动件的第二端部5316，第三牵动端53231牵动移动件531的第三端部5317，第四牵动端53241牵动移动件的第四端部5318，以牵动移动件531。
在一些实施例中，第一形变件5321、第二形变件5322、第三形变件5323以及第四形变件5324的材料为形状记忆合金(shape memory alloys，SMA)制作形成，形状记忆合金在通电状态下可以使得形状记忆合金被加热并使其变形，变形时可以使得形变件的长度发生变化，从而带动与其连接的移动件531移动。其中，移动件531与第一形变件5321、第二形变件5322、第三形变件5323以及第四形变件5324连接的端部(第一端部5315、第二端部5316、第三端部5317以及第四端部5318)可以向第一形变件5321、第二形变件5322、第三形变件5323以及第四形变件5324通电，移动件531可以与外部供电装置连接以实现电源传输，以使形变件形变，进而改变形变件的长度，驱动移动件531移动，从而带动与其连接的底板520移动，进而带动设置于底板520的感光元件200移动，实现感光元件200的防抖功能。
例如，可以通过对第一形变件5321和第三形变件5323通电，第一形变件5321和第三形变件5323的长度发生变化，以使与第一形变件5321和第三形变件5323连接的移动件531沿着X轴平移，通过对第二形变件5322和第四形变件5324通电，第二形变件5322和第四形变件5324长度发生变化，以使与第二形变件5322和第四形变件5324连接的移动件531沿着Y轴平移，可以同时对第一形变件5321和第二形变件5322通电，以使与第一形变件5321和第二形变件5322连接的531沿着预设轴转动，也可以同时对第一形变件5321和第四形变件5324通电，以使与第一形变件5321和第四形变件5324连接的531沿着预设轴转动，其中沿着预设轴转动可以顺时针转动或逆时针转动，可以理解的是，还可以同时对第一形变件5321、第二形变件5322、第三形变件5323以及第四形变件5324通大小不同的电流，控制形变件5321形变的长度，以实现移动件沿着X轴的平移、Y轴的平移或沿光轴/平行于光轴的预设轴转动。
本申请提供的实施例，可以通过上述检测装置540获取感光元件200移动量，进而可以计算得到感光元件200的偏移量，根据偏移量计算得到感光元件200的补偿数据，根据补偿数据控制移动装置530移动，带动感光元件200移动，进而实现感光元件200的防抖，例如，通过上述检测装置540检测到感光元件200朝向X轴正方向偏移了2个单位长度，则通过偏移量计算得到感光元件200的补偿数据(朝向X轴负方向平移2个单位长度)以使感光元件200回到初始位置，根据补偿数据控制移动装置530移动，具体的，可以对移动装置530的驱动件532通电，使得驱动件532的形变件形变，进而带动移动件531朝向X轴负方向平移2个单位长度，以带动和移动件531固定设置的感光元件200朝向X轴负方向平移2个单位长度，通过平移对感光元件200进行补偿仅仅是示例性的，通过本申请提供的防抖机构，还可以通过感光元件200沿光轴或平行于光轴的预设轴转动进行补偿，补偿逻辑如上所述，再次不再赘述。
可以理解的是，本申请实施例通过检测装置540可以实时反馈感光元件200的移动量，进而可以根据移动量控制移动装置530的移动量，对感光元件200的移动进行精确控制，提高感光元件200防抖能力。
由于底板520、设置于底板520的感光元件200以及移动装置530具有一定的重力，为了减少形变件对移动件的牵动力，提高防抖机构防抖的稳定性，防抖机构还包括柔性电路板模组550，柔性电路板模组500围绕设置于底板520的边缘，且和底板520的边缘连接，柔性电路板模组550还和壳体510连接，对于底板520的一部分具有支撑作用，降低了形变件通电形变时需要使移动件移动的牵动力，提高摄像装置防抖的稳定性。
本申请可以通过以下防抖模组对镜头进行防抖，请继续参阅图9，图9为图4所示防抖模组的爆炸结构图。
防抖模组400可以包括承载组件421、第一驱动组件422和第二驱动组件423。其中，承载组件421用于承载镜头440，第一驱动组件422和第二驱动组件423均设置在承载组件421上，而且第一 驱动组件422和第二驱动组件423为结构不同的两种驱动组件。第一驱动组件422能够驱动承载组件421沿平行于镜头440的光轴方向移动，当承载组件421沿平行于镜头440的光轴方向移动时可以带动镜头440一起沿平行于镜头440的光轴方向移动，以补偿镜头440在平行于镜头440的光轴方向的抖动量。第二驱动组件423能够驱动承载组件421沿垂直于镜头440的光轴方向移动，当承载组件421沿垂直于镜头440的光轴方向移动时可以带动镜头440一起沿垂直于镜头440的光轴方向移动，以补偿镜头440在垂直于镜头440的光轴方向的抖动量。
相比于相关技术中仅采用一个弹片式驱动马达或一个滚珠式驱动马达同时实现水平方向和竖直方向的位移，本申请实施例采用两个结构不同的驱动组件分别对承载组件进行两个不同方向的驱动，可以防止由于同一个驱动组件在同时实现两种不同方向的位移时导致驱动组件的部分部件损坏的情况，从而提高防抖模组400的防抖可靠性，提升防抖模组400的整体性能。
此外，经发明人长期研究发现，一些手机的弹片式驱动马达通常运用弹片结构以及吊环线结构实现驱动马达的水平方向以及竖直方向的位移以带动镜头的水平方向以及竖直方向的位移，然而在实现水平方向位移过程中容易出现弹片结构和/或吊环线断裂的问题；一些手机的滚珠式驱动马达通常采用多个滚珠实现驱动马达的水平方向以及竖直方向的位移以带动镜头的水平方向以及竖直方向的位移，然而在实现竖直方向的位移过程中，多个滚珠会相互撞击从而使得多个滚珠容易出现凹坑而导致滚动不顺畅的问题。
基于此，本申请实施例的第一驱动组件422包括弹性结构4221，弹性结构4221被配置为弹性作用力能够使得承载组件421沿平行于镜头440的光轴方向移动；第二驱动组件423包括滚动结构4231，滚动结构4231被配置为能够使得承载组件421基于滚动结构4231的滚动操作而实现沿垂直于镜头440的光轴方向移动。
可以理解的是，本申请实施例的第一驱动组件422通过弹性结构4221实现承载组件421的上下移动，第二驱动组件423通过滚动结构4231实现承载组件421的左右移动，相对于相关技术，可以避免弹性结构4221同时受到上下移动和左右移动等两个相互垂直的方向的拉扯而容易断裂的问题，以及可以避免滚动结构4231在实现上下移动过程中容易出现凹坑而导致滚动不顺畅的问题。
需要说明的是，本申请实施例中所有方向性指示(诸如上、下、左、右、前、后)仅用于解释在某一特定姿态下各部件之间的相对位置关系、移动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
承载组件421可以包括第一载体4211、第二载体4212和导向件4213，第二载体4212和导向件4213均设置在第一载体4211上。第一载体4211可以为规则形状，比如第一载体4211可以为矩形的框架结构，其可以具有依次连接的第一侧边42111、第二侧边42112、第三侧边42113和第四侧边42114，第一侧边42111和第三侧边42113相对设置，第二侧边42112与第四侧边42114相对设置。第一载体4211还设置有收纳空间42115，该收纳空间42115由第一侧边42111、第二侧边42112、第三侧边42113和第四侧边42114围设形成，其可以收纳防抖模组400的部分器件。当然，第一载体4211也可以为圆角矩形或不规则形状。
第二载体4212可以容置在收纳空间42115内，而且第二载体4212还可以在收纳空间42115内移动。其中，镜头440可以设置在第二载体4212上，当第二载体4212移动时可以带动镜头440移动。示例性的，第二载体4212也可以为矩形框架结构，其可以包括相互连接的第一支撑部42121、第二支撑部42122、第三支撑部42123和第四支撑部42124，第一支撑部42121和第三支撑部42123相对设置，第二支撑部42122与第四支撑部42124相对设置。第二载体4212可以设置有通孔42125，镜头440可以穿设于通孔42125，且与通孔42125的孔壁固定。
其中，当第二载体4212容置于收纳空间42115时，第一支撑部42121与第一侧边42111相对设置，第二支撑部42122与第二侧边42112相对设置，第三支撑部42123与第三侧边42113相对设置，第四支撑部42124与第四侧边42114相对设置。
导向件4213在平行于镜头440的光轴方向上层叠设置于第一载体4211的一部分上，以使得第一载体4211的一部分裸露于导向件4213外部。比如，导向件4213可以包括相互连接的第一侧部42131和第二侧部42132，其大致呈“L”型结构。第一侧部42131可以层叠在第一侧边42111上，第二侧部42132可以层叠在第二侧边42112上，以使得第三侧边42113和第四侧边42114裸露在导向件4213外部，或者说第三侧边42113和第四侧边42114未与导向件4213的一部分层叠设置。相比于相关技术中，矩形结构的导向件4213，本申请实施例的导向件4213可以减小导向件4213的体积，从而减少导向件4213对防抖模组400的空间占用，有利于防抖模组400的小型化。
防抖模组400还可以包括磁性组件424，磁性组件424可以为永磁体或者电磁铁，其可以产生磁场。其中磁性组件424可以设置在承载组件421上，而且磁性组件424可以包括多个磁性件，每一磁性件均可以包括磁性相反的两个磁体。
第一驱动组件422位于磁性组件424所产生的磁场内，而且第一驱动组件422在磁性组件424的作用下能够带动承载组件421沿平行于镜头440的光轴方向移动。比如，第一驱动组件422还可以包括第一导电件4222，第一导电件4222在垂直于镜头440的光轴方向上与磁性组件424相对设置，基于弗莱明左手定则，第一导电件4222通电之后可以产生一个磁场，第一导电件4222所产生的磁场可以与磁性组件424的磁场相互作用而产生垂直于镜头440的光轴方向第一作用力(或者说磁性作用力)，弹性结构4221能够产生垂直于镜头440的弹性作用力，第一作用力和弹性作用力同时作用于承载组件421，承载组件421在第一作用力和弹性作用力的驱动下，可以实现上下移动，从而带动镜头440上下移动，以实现镜头440的自动对焦和/或补偿镜头440在竖直方向上的抖动。
示例性的，第一驱动组件422可以包括两个第一导电件4222，两个第一导电件4222在垂直于镜头440的光轴方向上相对设置于第二载体4212的两侧，比如一个第一导电件4222可以设置在第一支撑部42121上，另一个第一导电件4222可以设置在第三支撑部42123上。两个第一导电件4222的结构可以相同，比如两个第一导电件4222可以均为图中所示的环状结构，第一支撑部42121和第三支撑部42123均可以设置有限位结构，一个第一导电件4222可以卡设在第一支撑部42121的限位结构上，另一个第一导电件4222可以卡设在第三支撑部42123的限位结构上。当然，两个第一导电件4222也可以为单杆结构或双杆结构。在一些实施例中，两个第一导电件4222的结构也可以不同，比如一个第一导电件4222可以为环状结构，另一个第一导电件4222可以为单杆结构或双杆结构等。
磁性组件424可以包括第一磁性件4241、第二磁性件4242和第三磁性件4243，第一磁性件4241、第二磁性件4242和第三磁性件4243可以均设置在第一载体4211上。
本申请实施例提供的防抖模组400可以实现对镜头100防抖，与防抖机构500配合以实现对镜头和感光元件的双防抖，例如根据抖动数据分别计算得到防抖模组400的第一补偿量和防抖机构500的第二补偿量，根据第一补偿量对镜头100抖动进行补偿，根据第二补偿量对感光元件抖动200进行补偿。
如图2所示，本申请实施例中的拍摄装置20还可以包括滤光片600，滤光片600设置在镜头100和感光元件200之间，滤光片600可以接收镜头100所采集到的外部光线，并对外部光线进行过滤处理(比如过滤杂色和偏光)，以便于提升拍摄装置20的成像效果。
需要说明的是，本申请实施例的拍摄装置20的结构并不限于此，诸如图10所示，图10为图1所示电子设备中拍摄装置的第二种结构框图。与上述申请实施例不同的是，本申请实施例中未设置有防抖模组400，直接将镜头100固定在支架300上，即本申请实施例中的镜头100固定不动，仅由防抖机构500驱动感光元件200移动以实现感光元件200防抖。
以上对本申请实施例提供的防抖机构、拍摄装置以及电子设备进行了详细介绍。本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请。同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
