具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。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”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。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。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的 摄像头模组进行详细地说明。
请参考图1～图9，本申请实施例公开一种摄像头模组，所公开的摄像头模组100应用于电子设备200，所公开的摄像头模组100包括第一采光镜110、第二采光镜120、第一反射件131、第二反射件132和感光芯片140。
第一反射件131位于第一采光镜110和第二采光镜120之间，且第一反射件131与第一采光镜110和第二采光镜120均相对设置。第一采光镜110和第二采光镜120用于采集环境光线，并将环境光线投射至第一反射件131。第二反射件132与第一反射件131相对设置，第二反射件132与感光芯片140相对设置。此时，第二反射件132位于第一反射件131所反射的光线的传输路径上。感光芯片140位于第二反射件132所反射的光线的传输路径上。第一采光镜110或第二采光镜120采集的光线依次通过第一反射件131和第二反射件132反射至感光芯片140。
具体的工作过程中，当摄像头模组100采用第一采光镜110采光时，第一采光镜110采集的光线通过第一反射件131和第二反射件132射入感光芯片140，从而可以实现前置拍摄；当摄像头模组100采用第二采光镜120采光时，第二采光镜120采集的光线通过第一反射件131和第二反射件132射入感光芯片140，从而实现可以后置拍摄。
本申请公开的实施例中，摄像头模组100可以通过双侧采光，从而使得一个摄像头模组100能够实现前后双摄，此时电子设备200仅需要设置一个摄像头模组100即可实现前后双摄，进而使得摄像头模组100占用电子设备200的安装空间较小，促使电子设备200的体积较小。
另外，电子设备200可以仅采用一个摄像头模组100即可实现前后双摄，从而能够减少摄像头的设置数量，进而降低电子设备200的制作成本。同时电子设备200内部无需预留两个摄像头模组100的安装空间，进而简化了电子设备200的空间布局。
上述实施例中，摄像头模组100还可以包括模组壳体，模组壳体为第一采光镜110、第二采光镜120、第一反射件131、第二反射件132、感光芯片 140以及其他摄像头模组100的组成部件提供安装基础。
为了进一步提高摄像头模组100的使用性能，在另一种可选的实施例中，第一反射件131与第二反射件132之间可以设置有调焦镜片组150，调焦镜片组150可以在第一反射件131和第二反射件132之间移动。此方案中，通过调节调焦镜片组150在第一反射件131和第二反射件132之间的位置，从而实现摄像头模组100的焦距的调节，进而能够实现摄像头模组100的长焦、短焦、微距等类型的拍摄，进一步提高摄像头模组100的使用性能。
调焦镜片组150具有多种组合结构，请参考图1，本文提供一种可选的实施方案，具体地，调焦镜片组150可以包括第一透镜151和第二透镜152，第一反射件131、第一透镜151、第二透镜152和第二反射件132依次间隔设置，也就是说，第一反射件131、第一透镜151、第二透镜152和第二反射件132沿一条直线分布。第一透镜151和第二透镜152可以在第一反射件131和第二反射件132之间移动。此方案中，通过第一透镜151和第二透镜152之间的位置调节，能够实现更大范围的焦距调节，从而实现摄像头模组100的更高倍数的变焦。
当然，调焦镜片组150内的透镜的数量不限于上文中的两个，还可以设置更多数量的透镜，从而实现不同倍数的变焦。
可选地，第一透镜151和第二透镜152可以均为凸透镜，也可以均为凹透镜，或者第一透镜151和第二透镜152中的一者为凸透镜另一者为凹透镜，对于第一透镜151和第二透镜152的具体类型，本文不作限制。
上述实施例中，调焦镜片组150在第一反射镜和第二反射镜之间的移动可以通过第一驱动装置实现，第一驱动装置与调焦镜片组150相连接，例如，第一驱动装置分别与第一透镜151和第二透镜152连接，第一驱动装置驱动第一透镜151和第二透镜152移动。第一驱动装置可以为驱动电机、气缸、形状记忆合金等动力结构，当然还可以采用其他动力结构，本文不作限制。
上述实施例中，第一透镜151和第二透镜152在移动的过程中，超出其移动行程，容易造成第一透镜151和第二透镜152发生碰撞，或者造成第一 透镜151和第二透镜152与摄像头模组100的其他部件发生碰撞。
基于此，摄像头模组100的模组壳体内可以设置有第一限位部，第一限位部可以沿第一透镜151和第二透镜152的移动方向与第一透镜151和第二透镜152限位配合。此方案能够防止第一透镜151和第二透镜152发生碰撞，同时还能够防止第一透镜151和第二透镜152与摄像头模组100的其他部件发生碰撞，从而提高了摄像头模组100的安全性。
可选地，第一限位部可以为设置于模组壳体内的凸起结构，当然还可以为其他结构，本文不作限制。
进一步地，第二反射件132和调焦镜片组150之间可以设置有对焦镜片160，对焦镜片160可以在第二反射件132和调焦镜片组150之间移动。此方案中，对焦镜片160能够将第一反射件131的反射光线的传输路径进行调节，从而使得光线射入感光芯片140时能够位于感光芯片140的焦点处，从而进一步提高摄像头模组100的拍摄质量。
可选地，对焦镜片160的移动可以通过第二驱动装置实现，第二驱动装置与对焦镜片160连接，第二驱动装置可以为驱动电机、气缸、形状记忆合金等动力结构，当然还可以采用其他动力结构，本文不作限制。
上述实施例中对焦镜片160可以为凸透镜，也可以为凹透镜，对焦镜片160与调焦镜片组150可以采用同种类型的透镜，只是其作用不同，对焦镜片160用于对焦，调焦镜片组150用于调焦。
上述实施例中，对焦镜片160在移动的过程中，也容易发生过度移动的现象，因此模组壳体内可以设置有第二限位部，第二限位部能够防止对焦镜片160过度移动，造成损坏。可选地，第二限位部可以为设置于模组壳体内的凸起结构，当然也可以为其他限位结构，本文不作限制。
上述实施例中，摄像头模组100内可以设置有驱动装置，驱动装置可以驱动第一反射件131转动。当使用第一采光镜110采光时，驱动装置驱动第一反射件131的反射面朝向第一采光镜110，从而使得第一反射件131能够将第一采光镜110采集的光线反射至第二反射件132。此时第一反射件131 的反射面因为背离第二采光镜120，因此第二采光镜120采集的光线不能被第一反射件131反射。
当使用第二采光镜120采集光线时，驱动装置驱动第一反射件131的反射面朝向第二采光镜120，从而使得第一反射件131能够将第二采光镜120采集的光线反射至第二反射件132。
此种结构中，驱动装置的结构复杂，且驱动机构与第一反射件131的连接较为复杂，因此使得摄像头模组100的结构复杂。同时，第一反射件131需要转动，因此摄像头模组100需要预留出第一反射件131的转动空间，从而使得摄像头模组100的体积较大。
基于此，在另一种可选的实施例中，摄像头模组100还可以包括第三反射件133和第四反射件134，第三反射件133和第二反射件132可以位于第一反射件131的相背两侧。第三反射件133与第四反射件134可以相对设置，第四反射件134与第二反射件132相对设置。
第一反射件131可以包括第一反射面和第二反射面，第一反射面朝向第一采光镜110，且朝向第二反射件132。第一反射面可以用于反射第一采光镜110采集的光线。第二反射面朝向第二采光镜120，且朝向第三反射件133，第二反射面可以用于反射第二采光镜120采集的光线。
第一反射面反射的光线可以射入第二反射件132。第二反射面反射的光线可以射入第三反射件133，第三反射件133再将光线反射至第四反射件134，由于第四反射件134与第二反射件132相对，因此第四反射件134再将光线反射至第二反射件132，经由第二反射件132反射后进入感光芯片140。
此时，摄像头模组的传输路径为两条，第一条由第一采光镜110、第一反射面、第二反射件132构成。如图2中的实线箭头所示的传输路径。第二条由第二采光镜120、第二反射面、第三反射件133、第四反射件134和第二反射件132构成。如图2中的虚线箭头所述的传输路径。
此方案中，第一反射件131通过不同的反射面形成两条光路传输路径，无需转动第一反射件131，因此摄像头模组100无需设置驱动装置驱动第一 反射件131，进而使得摄像头模组100的结构简单。另外，第一反射件131不需要转动，因此摄像头模组100无需预留第一反射件131的转动空间，使得摄像头模组100的体积更小。
上述实施例中，在第一反射件131指向第二反射件132的方向上，第一反射件131和第四反射件134的投影轮廓可以位于第二反射件132的投影轮廓内，从而使得第一反射件131反射的光线和第四反射件134反射的光线均能够射入第二反射件132。
可选地，第一反射件131可以为柱状结构，例如，三棱柱、四棱柱、圆柱等结构，第一反射面和第二反射面可以为柱状结构的对角的斜面。或者第一反射件131可以为两个三棱柱拼接而成，两个三棱柱的拼接面分别为第一反射面和第二反射面，也就是说，第一反射面和第二反射面相平行。第一反射面和第二反射面均可以与三棱柱的入光面的夹角可以为45°。两个三棱镜可以分别与第一采光镜110和第二采光镜120粘接。当然，第一反射件131还可以为其他结构本文不作限制。
在另一种方案中，第二反射件132也可以为三棱柱，三棱柱的斜面即为第二反射件132的反射面，第二反射件132的反射面与感光芯片140的夹角可以为45°。当然，第二反射件132还可以为其他结构，本文不作限制。
上述实施例中，第三反射件133和第四反射件134的形状与第二反射件132可以相同，仅是第三反射件133和第四反射件134的体积小于第二反射件132的体积。另外，第三反射件133和第四反射件134还可以为一体式结构，对于第三反射件133和第四反射件134的具体结构，本文不作限制。
上述实施例中，第四反射件134反射的光线需要经过调焦镜片组150和对焦镜片160，因此第四反射件134和第一反射件131的投影轮廓也都位于调焦镜片组150和对焦镜片160的投影轮廓之内。
上述实施例中，第一反射面和第二反射面反射的光线容易发生散射，从而导致射入第二反射件132的光线数量较少，进而使得感光芯片140接收到的光线数量较少。
基于此，在另一种可选的实施例中，本申请公开的摄像头模组100还可以包括第一光路准直镜片171和第二光路准直镜片172，第一光路准直镜片171可以位于第一反射件131与第二反射件132之间。第二光路准直镜片172可以位于第一反射件131与第三反射件133之间。
此方案中，第一光路准直镜片171和第二光路准直镜片172可以将发散光线变为平行光线，从而提高摄像头的光线利用率，进而提高摄像模组的光学性能。
上述实施例中，第二反射件132、对焦镜片160、调焦镜片组150、第一光路准直镜片171、第一反射件131、第二光路准直镜片172和第三反射件133可以位于一条直线上，感光芯片140可以位于第二反射件132的下方，第四反射件134可以位于第三反射件133的下方，且与感光芯片140可以位于同一侧。
用户通常手持电子设备200进行图像的拍摄，由于手持拍摄中会发生抖动，进而会导致电子设备200的拍摄图像质量较差。
基于此，在另一种可选的实施例中，本申请公开的摄像头模组100还可以包括防抖腔室180，防抖腔室180可以开设够贯通腔181。贯通腔181是指由防抖腔室180的一侧向另一侧贯通。第一采光镜110、第一反射件131和第二采光镜120可以沿贯通腔181的轴线方向分布，且设置于贯通腔181内。第一采光镜110和第二采光镜120可以通过贯通腔181外露于防抖腔室180。
防抖腔室180内可以设置有驱动机构，驱动机构可以与第一反射件131相连接，驱动机构可以驱动第一反射件131带动第一采光镜110和第二采光镜120在贯通腔181内运动。
此方案中，驱动机构能够驱动第一采光镜110、第二采光镜120和第一反射件131沿着摄像头模组100抖动的相反方向运动，从而能够对摄像头模组100的抖动量进行补偿，进而能够实现摄像头模组的防抖功能，以提高摄像头模组100的拍摄质量。
摄像头模组100在拍摄过程中，当用户出现手抖的情况，陀螺仪检测到 摄像头模组100倾斜，陀螺仪将获取摄像头模组100的倾斜角度等数据传输给控制芯片，控制芯片输入相应的角度补偿量，然后驱动机构驱动第一采光镜110和第二采光镜120运动，从而实现防抖。
上述的控制芯片可以为摄像模组的控制芯片，也可以是电子设备200中的控制芯片，控制芯片为公知技术，本文不再赘述。
上述方案中，第一采光镜110、第二采光镜120和第一反射件131可以沿着第一平面移动，该第一平面可以与光轴相垂直，第一平面与贯通腔181的轴线相垂直，也就是说，贯通腔181的轴线与光轴相平行。和/或，第一采光镜110、第二采光镜120和第一反射件131可以沿着至少一条第一平面上的轴线转动。和/或，第一采光镜110、第二采光镜120和第一反射镜可以沿光轴转动。对于第一采光镜110、第二采光镜120和第一反射件131的移动方向本文不作限制。
上述实施例中，驱动机构可以为驱动电机、气缸、形状记忆合金等动力结构，当然，还可以采用其他动力结构，本文不作限制。
可选地，第一反射件131的反射光线需要反射至第二反射件132，因此防抖腔室180需要透光。此时，防抖腔室180朝向第一反射件131的反射面的一侧可以采用透光材料制作，例如，透明玻璃、透明塑料等材料制作。或者防抖腔室180朝向第一反射件131的反射面的一侧可以开设有透光孔，从而用于第一反射件131的光路传输。此处的第一反射件131的反射面包括上文中的第一反射面和第二反射面。
上述实施例中，驱动电机、气缸等动力结构体积较大，占用较大的防抖腔室180的安装空间，从而使得摄像头模组100的体积较大。另外，驱动电机和气缸等动力结构的换向时间长，第一反射件131的灵敏度较差，从而使得防抖性能较差。
在另一种可选的实施例中，驱动机构可以包括线圈和磁铁，防抖腔室180和第一反射件131中，一者可以设置有线圈，另一者可以设置有磁铁。线圈与磁铁可以相对设置。在线圈通电的情况下，第一采光镜110、第一反射件 131和第二采光镜120可以在贯通腔181内运动。
具体的操作过程中，请参考图6和图7，图6为摄像头模组为未发生抖动时的示意图，图7为摄像头模组发生抖动时的示意图。当线圈通电时，通电线圈在磁铁产生的磁场内会产生安培力，从而驱动第一反射件131移动。第一反射件131的具体的运动方向可以通过左手定则判断，第一反射件131的运动方向与线圈和磁铁设置位置以及数量有关，因此可以根据具体的防抖需求，排布线圈和磁铁。
此方案中，线圈与磁铁的结构简单，体积较小，因此使得摄像头模组100的体积较小。另外，线圈通入不同方向的电流，从而产生不同方向的安培力，使得第一反射件131的换向时间短，第一反射件131的灵敏度较高，从而提高了摄像头模组100的防抖性能。
上述实施例中，第一反射件131与防抖腔室180可以通过滚珠、转轴等部件活动连接，然后，滚珠转轴等部件限制了第一反射件131的运动方向，从而使得防抖性能较差。
在另一种可选的实施例中，磁铁的数量可以为多个，线圈的数量可以为多个。第一反射件131可以包括多个侧面，每个侧面均可以设置有至少一个磁铁或线圈，多个线圈和多个磁铁一一对应设置。
此方案中，当摄像头模组100未发生抖动时，第一反射件131的外周都设置有磁铁或者线圈，因此通过每个侧面的线圈和磁铁的相互配合，从而实现第一反射件131的悬浮。处于悬浮状态的第一反射件131可以在贯通腔181内具有沿任意角度及方向运动的趋势，因此提高了摄像头模组100的防抖范围，能够实现摄像头的三维防抖。
当摄像头模组100发生抖动时，可以通过调整线圈内电流的大小以及电流的方向，从而可以通过第一反射件131所受的驱动力的方向和大小，以控制第一反射件131在贯通腔181内运动。
在摄像头防抖过程中，由于磁滞效应的影响，当线圈内的电流回复到初始值，初始值是指第一反射件131为发生运动时的线圈内的电流的数值。第 一反射件131受到的驱动力并非直接降低到初始情况，而是缓慢的逐步减小到初始状态。初始状态是指上文中的悬浮状态。在驱动力缓慢变化的过程中，第一反射件131也随之缓慢运动，从而能够实现摄像头模组100拍摄过程中的全过程防抖，进一步提高了摄像头模组100的拍摄质量。磁滞效应为公知常识，本文不作具体论述。
可选地，第一反射件131可以为四棱柱，四棱柱的六个面上均可以设置有线圈，防抖腔室180也可以为四棱柱，四棱柱的六个面上均可以设置有磁铁。或者防抖腔室180可以采用磁性材料制作。第一反射件131的每个面上可以有多个小线圈组成，通过多个小线圈的驱动力的不同，可以实时摄像头模组100的更多方向和角度的运动。
在另一种可选的实施例中，相对的两个磁铁的磁极相同，此方案能够保证防抖腔室180内磁通量为零，避免磁场对拍摄画质的影响。
基于本申请实施例公开的摄像头模组100，本申请实施例还公开一种电子设备200，所公开的电子设备200包括上文任一实施例所述的摄像头模组100。电子设备200朝向显示屏的一侧开设有第一透光区域201，电子设备200背离显示屏的一侧可以开设有第二透光区域202。第一透光区域201可以与第二透光区域202相对，第一采光镜110与第一透光区域201可以相对设置，第二采光镜120与第二透光区域202可以相对设置。
环境光线能够透过第一透光区域201进入第一采光镜110，第一采光镜110采集的光线通过第一反射件131和第二反射件132射入感光芯片140，从而可以实现前置拍摄。环境光线能够透过第二透光区域202进入第二采光镜120，第二采光镜120采集的光线通过第一反射件131和第二反射件132射入感光芯片140，从而可以实现后置拍摄。
此方案中，摄像头模组100可以通过双侧采光，从而使得一个摄像头模组100能够实现前后双摄，此时电子设备200仅需要设置一个摄像头模组100即可实现前后双摄，进而使得摄像头模组100占用电子设备200的安装空间较小，促使电子设备200的体积较小。
可选地，电子设备200的设备壳体可以包括前壳和后盖，前壳用于安装显示显示屏，第一透光区域201可以开设在前壳上，第二透光区域202可以开设在后盖上。或者，第一透光区域201可以开设于显示屏上，摄像摄像头模组100位于显示屏的下方。第一透光区域201和第二透光区域202可以为通孔，也可以为设备壳体或者显示屏上采用透明材料制作的区域。
上述实施例中，电子设备200在进行前置拍摄时，第二采光镜120也能够采光，从而对前置拍摄造成影响。
基于此，在另一种可选的实施例中，电子设备200还可以包括可活动的第一遮挡件和第二遮挡件，第一遮挡件和第二遮挡件可以位于电子设备200的相对两侧，第一遮挡件可以位于第一透光区域201与第一采光镜110之间，第二遮挡件可以位于第二透光区域202与第二采光镜120之间，第一遮挡件可以用于遮挡第一透光区域201，第二遮挡件可以用于遮挡第二透光区域202。
具体的操作过程中，当电子设备200前置拍摄时，第二遮挡件可以对第二透光区域202进行遮挡，从而使得环境光线不能进入第二采光镜120，切断了第二采光镜120的光线采集路径，从而不容易对电子设备200的前置拍摄造成影响。
当电子设备200后置拍摄时，第一遮挡件可以对第一透光区域201进行遮挡，从而使得环境光线不能进入第一采光镜110，切断了第一采光镜110的光线采集路径，从而不容易对电子设备200的后置拍摄造成影响。
此方案能够进一步提高电子设备200的拍摄质量。
可选地，第一遮光件和第二遮光件可以设置于设备壳体之外，第一遮光件和第二遮光件可以通过转轴与设备可以转动连接，当第一透光区域201和第二透光区域202需要遮光时，用户可以通过手动转动第一遮光件和第二遮光件遮盖第一透光区域201和第二透光区域202。
再或者，第一遮光件和第二遮光件可以设置于设备壳体之内，第一遮光件和第二遮光件分别与第一驱动电机和第二驱动电机连接，当第一透光区域201和第二透光区域202需要遮光时，用户可以通过第一驱动电机和第二驱 动电机驱动第一遮光件和第二遮光件转动，从而遮盖第一透光区域201和第二透光区域202。
可选地，第一遮光件和第二遮光件可以为不透光的金属薄片、或者不透光的塑胶薄片，当然，第一遮光件和第二遮光件可以采用其他材料制作。
本申请实施例公开的电子设备可以是智能手机、平板电脑、电子书阅读器、可穿戴设备(例如智能手表)、电子游戏机等设备，本申请实施例不限制电子设备的具体种类。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
