请参阅图2及图6，本申请实施方式的第一摄像头模组20包括外壳21、棱镜22和第一图像传感器26。
外壳21开设有进光口211，棱镜22设置在外壳21内，棱镜22用于将从进光口211入射的入射光转向后传至第一图像传感器26，以使第一图像传感器26感测第一摄像头模组20外部的光线，其中，棱镜22包括棱边222，棱边222倒钝处理以形成倒角或圆角。
上述第一摄像头模组20中，通过对棱镜22的棱边222做倒钝处理以形成倒角或圆角，使棱镜22原本的边缘的角部分变的相对平滑圆润，降低了棱镜22在受到冲击时导致棱镜22边缘部分被损坏的风险，保证了棱镜22的使用寿命，并确保了摄像头组件100与电子装置1000的成像质量。

请参阅图6及图7，在某些实施方式中，运动元件25呈筒状，多个镜片241沿运动元件25的轴向间隔固定在运动元件25内；或，运动元件25包括两个夹片252，两个夹片252夹设多个镜片241。
本发明实施方式的摄像头组件100包括第一摄像头模组20。
请参阅图2-3及图8，在某些实施方式中，在第一摄像头模组20的宽度方向上，外壳21在进光口 211的一侧形成有凹槽212，摄像头组件100包括装饰件10，装饰件10罩设在进光口211上方并部分地卡入凹槽212中，装饰件10形成有通孔11，进光孔211通过通孔11露出，第一摄像头模组20通过通孔11采集外界图像。
请参阅图2、图4及图5，在某些实施方式中，外壳21包括顶壁213和侧壁214。侧壁214自顶壁213的侧边2131延伸形成。进光口211形成于顶壁213，凹槽212形成在顶壁213和侧壁214的连接处，装饰件10抵靠在顶壁213上。
在某些实施方式中，凹槽212呈长条状，凹槽212沿第一摄像头模组20的长度方向延伸。或，凹槽212可呈弧形，弧形的凹槽212围绕进光口211。
在某些实施方式中，侧壁214的数量为两个，顶壁213包括相背的两个侧边2131，侧壁214的数量为两个，每个侧壁214自对应的一个侧边2131延伸，每个侧壁214与顶壁213的连接处均形成有凹槽212。
在某些实施方式中，装饰件10包括装饰圈12和凸边13，凸边13自装饰圈12的底部向远离装饰圈12的方向延伸。装饰圈12的部分底部收容于凹槽212中，装饰圈12部分抵靠在顶壁213上。
请参阅图1，本申请实施方式的电子装置1000包括机壳102和摄像头组件100。摄像头组件100设置在机壳102上。电子装置1000可以是手机、平板电脑、笔记本电脑、智能手环、智能手表、智能头盔、智能眼镜等。本申请实施方式以电子装置1000是手机为例进行说明，可以理解，电子装置1000的具体形式可以是其他，在此不作限制。
具体地，机壳102为电子装置1000的外部零部件，其起到了保护电子装置1000的内部零件的作用。机壳102可以为电子装置1000的后盖，其覆盖电子装置1000的电池等零部件。本实施方式中，摄像头组件100后置，或者说，摄像头组件100设置在电子装置1000的背面以使得电子装置1000可以进行后置摄像。如图1的示例中，摄像头组件100设置在机壳102的左上角落部位。当然，可以理解，摄像头组件100可以设置在机壳102的中上位置或右上位置等其他位置。摄像头组件100设置在机壳102的位置不限制于本申请的示例。
请参阅图2及图3，摄像头组件100包括装饰件10、第一摄像头模组20、第二摄像头模组30和支架40。装饰件10设置在机壳102上，并凸出于机壳102的表面。第一摄像头模组20和第二摄像头模组30均设置在机壳102内部。第一摄像头模组20和第二摄像头模组30均靠近装饰件10设置。第一摄像头模组20和第二摄像头模组30均设置在支架40内并与支架40固定连接。装饰件10设置在支架40的上方，具体地，装饰件10可以抵靠在支架40上，也可以与支架10间隔设置。支架40可以减少第一摄像头模组20、第二摄像头模组30受到的冲击，提高第一摄像头模组20和第二摄像头模组30寿命。
装饰件10可以采用金属材料制成，例如装饰件10的材料为不锈钢，装饰件10可以通过抛光工艺处理以形成光亮的表面，以使装饰件10更加美观。
请结合图4，装饰件10形成有通孔11，第一摄像头模组20和第二摄像头模组30均从通孔11露出于装饰件10，或者说，第一摄像头模组20和第二摄像头模组30均通过通孔11采集外界图像。具体地，本实施方式中，通孔11包括第一子孔111和第二子孔112，第一子孔111和第二子孔112间隔设置。或 者说，第一子孔111和第二子孔112是不连通的。当然，在其他实施方式中，第一子孔111和第二子孔112可以连通而形成一个整体孔。第一摄像头模组20通过第一子孔111采集外界图像，第二摄像头模组30通过第二子孔112采集外界图像。本实施方式中，第一子孔111为圆形孔，第二子孔112为方形孔。
在其他实施方式中，第一子孔111和第二子孔112的形状不限于图示中的形状。例如，第一子孔111和第二子孔112均为圆形孔；又如，第一子孔111和第二子孔112均为方形孔。
装饰件10包括装饰圈12和凸边13，凸边13自装饰圈12的底部向远离装饰圈12的方向延伸。通孔11形成于装饰圈12，并贯穿装饰圈12和凸边13，装饰圈12安装在机壳102上，凸边13抵靠在机壳102上，如图10所示。如此，凸边13可以限制装装饰件10的位置，防止装饰件10向机壳102外移动。在一个例子中，在安装装饰件10时，装饰件10从机壳102的内部向外插装，在凸边13抵靠机壳102的内表面时，装饰件10安装到预定位置。装饰件10可以使用粘胶固定在机壳102上，也可以使装饰件10与机壳102过盈配合，从而使得装饰件10不易从机壳102上脱落。
装饰件10可以为装饰圈12与凸边13形成的一体成型结构，例如，装饰件10采用切削加工的方式制造形成。另外，装饰圈12与凸边13也可以为分体结构，或者说，装饰圈12与凸边13先形成两个独立的元件，然后通过焊接等工艺组装在一起从而形成装饰件10。
需要指出的是，在其他实施方式中，凸边13可以省略，也就是说，在此实施方式中，装饰件10只包括装饰圈12的结构。
第一摄像头模组20和第二摄像头模组30并列排布，也即是说，第二摄像头模组30设置在第一摄像头模组20一侧。本实施方式中，第一摄像头模组20和第二摄像头模组30排列成一字型，或者说，第一摄像头模组20和第二摄像头模组30沿同一直线排布。在其他实施方式中，第一摄像头模组20和第二摄像头模组30可以排列成L型。第一摄像头模组20和第二摄像头模组30可以间隔设置，也可以相互抵靠在一起。
本实施方式中，第一摄像头模组20位于第二摄像头模组30的右侧，或者说，第一摄像头模组20相较于第二摄像头模组30更加靠近电子装置1000的中间位置。当然，可以理解，在其他实施方式中，第一摄像头模组20和第二摄像头模组30的位置可以互换，或者说，第一摄像头模组20位于第二摄像头模组30的左侧。
在第一摄像头模组20和第二摄像头模组30中，其中一个摄像头模组可以为黑白摄像头，另外一个摄像头模组为RGB摄像头；或者一个摄像头模组为红外摄像头，另外一个摄像头模组为RGB摄像头；或者一个摄像头模组为RGB摄像头，另外一个摄像头模组也为RGB摄像头；或者一个摄像头模组为广角摄像头，另外一个摄像头模组为长焦摄像头等。
在其他实施方式中，第二摄像头模组30可以省略，或者电子装置1000可以包括三个以上的摄像头模组。
请参阅图5-7，本实施方式中，第一摄像头模组20包括外壳21、棱镜22、安装座23、第一透镜组件24、运动元件25、驱动机构27和第一图像传感器26。棱镜22、安装座23、第一透镜组件24、运动元件25均设置在外壳21内。棱镜22设置在安装座23上，第一透镜组件24收容于运动元件25内，驱 动机构27连接运动元件25与外壳21。入射光进入外壳21后，经过棱镜22转向，然后透过第一透镜组件24到达第一图像传感器26，从而使得第一图像传感器26获得外界图像。而驱动机构27驱动运动元件25以带动第一透镜组件24的运动，使第一摄像头模组20达到对焦的效果。
如图6，在某些实施方式中，第一透镜组件24包括多个镜片241。运动元件25呈筒状，多个镜片241沿运动元件25的轴向间隔固定在运动元件25内；或如图7，运动元件25包括两个夹片252，两个夹片252夹设多个镜片241。
可以理解，由于运动元件25用于固定设置多个间隔设置的镜片241，所需运动元件25的长度尺寸较大，运动元件25可以为圆筒状、方筒状等具备较一定腔体的形状，如此运动元件25呈筒装可更好的设置多个镜片241，并且可更好的保护镜片241于腔体内，使镜片241不易发生晃动。
另外，运动元件25为两个夹片252将多个镜片241夹持于两个夹片252之间，既具备一定的稳定性，也可降低运动元件25的重量，可以降低驱动机构27驱动运动元件25所需的功率，并且运动元件25的设计难度也较低，镜片241也较易设置于运动元件25上。
当然，运动元件25不限于上述提到的筒状与两个夹片252，在其他的实施方式中，运动元件25如可包括三片、四片等更多的夹片252形成更稳固的结构，或一片夹片252这样更为简单的结构；抑或为矩形体、圆形体等具备腔体以容置镜片241的各种规则或不规则的形状。在保证成像模组10正常成像和运行的前提下，具体选择即可。
外壳21大致呈方块形，外壳21开设有进光口211，入射光从进光口211进入第一摄像头模组20内。也就是说，棱镜22用于将从进光口211入射的入射光转向后传至第一图像传感器26。因此可以理解，第一摄像头模组20为潜望式镜头模组，相较于立式镜头模组，潜望式镜头模组的高度较小，从而可以降低电子装置1000的整体厚度。立式镜头模组指的是镜头模组的光轴为一条直线，或者说，入射光沿着一直线光轴的方向传导至镜头模组的感光器件上。
可以理解，进光口211通过通孔11露出以使外界光线经过通孔11后从进光口211进入第一摄像头模组20内。
请结合图8，本实施方式中，在第一摄像头模组20的宽度方向上，外壳21在进光口211的一侧形成有凹槽212，装饰件10罩设在进光口211上方并部分地卡入凹槽212。
请参阅图10，如果省略凹槽，为了使得电子装置的整体厚度较薄，潜望式摄像头模组20a在宽度方向上部分伸入装饰件10a内，由于潜望式摄像头模组20a的宽度相较于立式的摄像头模组的宽度大，那么此时，装饰件10a的尺寸则较大，不利于电子装置美观，也使得电子装置不够紧凑。
请再次参阅图5及图8，而本实施方式中，凹槽212形成在进光口211的一侧，装饰件10罩设在进光口211上方并部分地卡入凹槽212中，不仅使得装饰件10的宽度尺寸较小，还可以使得摄像头组件100的整体高度尺寸减小，有利于摄像头组件100结构紧凑、小型化。
具体地，外壳21包括顶壁213和侧壁214。侧壁214自顶壁213的侧边2131延伸形成。顶壁213包括相背的两个侧边2131，侧壁214的数量为两个，每个侧壁214自对应的一个侧边2131延伸，或者说，侧壁214分别连接顶壁213相背的两侧。进光口211形成于顶壁213，凹槽212形成在顶壁213和 侧壁214的连接处，装饰件10抵靠在顶壁213上。如此，凹槽212容易形成，有利于外壳21制造。在一个例子中，凹槽212为外壳21的压型，即，凹槽212可以通过冲压的方式形成。
在一个例子中，装饰圈12的部分底部收容于凹槽212中，装饰圈12部分抵靠在顶壁213上。或者说，装饰圈12与外壳21形成互补的结构，装饰圈12与外壳21相互嵌合，以使装饰件10与外壳21的配合结构更加紧凑。
本实施方式中，每个侧壁214与顶壁213的连接处均形成有凹槽212。或者说，凹槽212的数量为两个。当然，在其实施方式中，凹槽212的数量也可为单个，即是说，其中一个侧壁214与顶壁213的连接处形成有凹槽212。
本实施方式中，凹槽212呈长条状，凹槽212沿第一摄像头模组20的长度方向延伸。如此，凹槽212与装饰件10配合得更加紧凑。在一些实施方式中，凹槽212可呈弧形，弧形的凹槽212围绕进光口211。当然，在其他实施方式中，凹槽212的结构和形状不限于上述的例子，只要使得装饰件10与第一摄像头模组20形成互补结构以减小装饰件10的尺寸即可。
在一个例子中，棱镜22为三角棱镜，棱镜22的截面为直角三角形，其中，光线从直角三角形中的其中一个直角边入射，经过斜边的反射后从而另一个直角边出射。可以理解，当然，入射光可以经过棱镜22折射后出射，而不经过反射。棱镜22可以采用玻璃、塑料等透光性比较好的材料制成。在一个实施方式中，可以在棱镜22的其中一个表面涂布银等反光材料以反射入射光。
请参阅图12与图13，棱镜22包括棱边222，棱边222倒钝处理以形成倒角或圆角。可以理解，棱镜22包括直角面与锐角面，其中棱边222所形成的棱镜22的边缘部分，在受到外部冲击时易被破坏，因此对棱边222做倒角或圆角处理，使棱镜22的各个棱边222处形成较为平滑圆润的结构，可以降低棱镜22在受到冲击时的损害。
在一个例子中，对棱镜22的所有棱边222做圆角处理，以使棱镜22的所有边缘部分形成圆角结构，以提高棱镜22整体的强度；
在另一个例子中，对棱镜22的所有棱边222做倒角处理，以使棱镜22的所有边缘部分形成倒角结构，以提高棱镜22整体的强度。
在一些例子中，对棱镜22的部分棱边222做倒角处理，部分棱边222做圆角处理。
在一些例子中，可对棱镜22的三个较短棱边222处做倒角或圆角处理，以降低加工成本与加工时长。当然，也可以对棱镜22的其中一条或多条棱边222选择性的做倒角或圆角处理，以适应更多的实施方式。
在一个例子中，棱镜22将从进光口211入射的入射光转向的角度为90度。例如，入射光在棱镜22的发射面上的入射角为45度，反射角也为45度。当然，棱镜22将入射光转向的角度也可为其他角度，例如为80度、100度等，只要能将入射光转向后到达第一图像传感器26即可。
本实施方式中，棱镜22的数量为单个，此时，入射光经过一次转向后传至第一图像传感器26。在其他实施方式中，棱镜22的数量为多个，此时，入射光经过至少两次转向后传至第一图像传感器26。
在某些实施方式中，棱边222的圆角的半径为0.1-0.15mm，或棱边222的倒角的尺寸为0.1-0.15mm。
上述棱边222的圆角的半径范围与棱边222的倒角的尺寸适中，既可保证棱镜22的整体构造较为 完整，也可确保棱镜22的强度，实施起来也较为容易。当然，圆角的半径与倒角的尺寸也不限上面提到的范围，在具体的实施方式中具体选择即可。
棱边222的倒角的尺寸为0.1-0.15mm指的是：倒角的任意一条倒角直边的尺寸为0.1-0.15mm，倒角直边的尺寸例如为0.1mm、0.11mm、0.12mm等尺寸。
棱边222的圆角的半径例如为0.1mm、0.11mm、0.12mm等尺寸。
在某些实施方式中，棱镜22的外表面226经过硬化处理并形成有硬化层。
棱镜22本身的材质较脆，为了提高棱镜22的强度，可在对棱镜22的外表面226做硬化处理，硬化处理如渗入锂离子、在不影响棱镜22转换光线的前提下给外表面226贴膜等。
安装座23用于安装棱镜22，或者说，安装座23为棱镜22的载体，棱镜22固定设置在安装座23上。这样使得棱镜22的位置可以确定，有利于棱镜22反射或折射入射光。棱镜22可以采用粘胶粘接固定在安装座23上以实现与安装座23固定连接。
请参图6，在一个例子中，安装座23可活动设置在外壳21内，安装座23能够相对于外壳21绕转动轴线232转动以调整棱镜22将入射光转向的方向，与转动轴线232的延伸方向一致的棱边224形成的倒角或圆角的尺寸大于其他棱边222形成的倒角或圆角的尺寸。如此，棱镜22转动时可以防止该方向上的棱边224与第一成像模组20的其他元件干涉。
安装座23可以带动棱镜22一起朝向第一摄像头模组20的抖动的反方向转动，从而补偿进光口211的入射光的入射偏差，实现光学防抖的效果。安装座23可以与驱动机构27连接，驱动机构27可以驱动安装座23转动。更多的，与转动轴线232的延伸方向一致的棱边224可以指的是，棱边224的延伸方向与转动轴线232的延伸方向可以是相互平行的，也可以是相对略有倾斜。
第一透镜组件24收容于运动元件25内，进一步地，第一透镜组件24设置在棱镜22和第一图像传感器26之间。第一透镜组件24用于将入射光成像在第一图像传感器26上。这样使得第一图像传感器26可以获得品质较佳的图像。
第一透镜组件24沿着其光轴整体移动时可以在第一图像传感器26上成像，从而实现第一摄像头模组20对焦。第一透镜组件24包括多个镜片241，当至少一个镜片241移动时，第一透镜组件24的整体焦距改变，从而实现第一摄像头模组20变焦的功能，更多的，由驱动机构27驱动运动元件25在外壳21中运动以达到变焦目的。
第一图像传感器26可以采用互补金属氧化物半导体(CMOS，Complementary Metal Oxide Semiconductor)感光元件或者电荷耦合元件(CCD，Charge-coupled Device)感光元件。
在某些实施方式中，驱动机构27为电磁驱动机构、压电驱动机构或记忆合金驱动机构。
具体地，电磁驱动机构中包括磁场与导体，如果磁场相对于导体运动，在导体中会产生感应电流，感应电流使导体受到安培力的作用，安培力使导体运动起来，此处的导体为电磁驱动机构中带动运动元件12移动的部分；压电驱动机构，基于压电陶瓷材料的逆压电效应：如果对压电材料施加电压，则产生机械应力，即电能与机械能之间发生转换，通过控制其机械变形产生旋转或直线运动，具有结构简单、低速的优点。
记忆合金驱动机构的驱动基于形状记忆合金的特性：形状记忆合金是一种特殊的合金，一旦使它记忆了任何形状，即使产生变形，但当加热到某一适当温度时，它就能恢复到变形前的形状，以此达到驱动的目的，具有变位迅速、方向自由的特点。
请参阅图9，本实施方式中，第二摄像头模组30为立式镜头模组，当然，在其他实施方式中，第二摄像头模组30也可以潜望式镜头模组。第二摄像头模组30包括第二透镜组件31和第二图像传感器32，第二透镜组件31用于将光线在第二图像传感器32上成像，第二摄像头模组30的入射光轴与第二透镜组件31的光轴重合。
本实施方式中，第二摄像头模组30为定焦镜头模组，因此，第二透镜组件31的镜片241较少，以使第二摄像头模组30高度较低，有利于减小电子装置1000的厚度。
第二图像传感器32的类型可与第一图像传感器26的类型一样，在此不再赘述。
综上，本申请实施方式的第一摄像头模组20包括外壳21、棱镜22和第一图像传感器26。
外壳21开设有进光口211，棱镜22设置在外壳21内，棱镜22用于将从进光口211入射的入射光转向后传至第一图像传感器26，以使第一图像传感器26感测第一摄像头模组20外部的光线，其中，棱镜22包括棱边222，棱边222倒钝处理以形成倒角或圆角。
本申请实施方式的摄像头组件100的组装过程大致如下：
提供第一摄像头模组20和棱镜22，其中，第一摄像头模组包括外壳21、棱镜22和第一图像传感器26，外壳21开设有进光口211，棱镜22设置在外壳21内，棱镜22用于将从进光口211入射的入射光转向后传至第一图像传感器26，以使第一图像传感器26感测第一摄像头模组20外部的光线，其中，棱镜22包括棱边222，棱边222倒钝处理以形成倒角或圆角。
上述摄像头组件100与电子装置1000中，通过对棱镜22的棱边222做倒钝处理以形成倒角或圆角，使棱镜22原本的边缘的角部分变的相对平滑圆润，降低了棱镜22在受到冲击时导致棱镜22边缘部分被损坏的风险，保证了棱镜22的使用寿命，并确保了摄像头组件100与电子装置1000的成像质量。
