本申请主张2021年02月20日在中国提交的中国专利申请号202110192830.9的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于电子设备技术领域，具体涉及一种摄像头模组和一种电子设备。
背景技术
随着手机的摄影功能的不断发展，摄像头的数量也随之变多，由于每个摄像头均带有自动对焦功能，随之带来的是单独设置一个距离传感器，以通过距离传感器测量被拍物体的距离。如图1所示，现有距离传感器会占用有限的手机空间，同时其光轴与摄像头并不一致，无法精确计算对焦点，在一些特殊的角度下，如图2所示，会存在两个不重合区域，在不重合区域内无法使用激光传感器辅助摄像头对焦，极大的影响用户的使用体验。
发明内容
本申请旨在提供一种摄像头模组和一种电子设备，至少解决对焦偏移的问题。
为了解决上述技术问题，本申请是这样实现的：
第一方面，本申请实施例提出了一种摄像头模组，包括：反射件，反射件上设有反光透光面；镜片组件和图像传感器，设于反射件的一侧，经 出光面向外射出的光线经镜片组件射入图像传感器；滤波反射层，设于反光透光面上，滤波反射层能够反射第一频段的光线，且滤波反射层能够透过第二频段的光线；激光传感器，设于反光透光面远离进光面的一侧，且在激光传感器的安装面上，滤波反射层的投影与激光传感器至少部分重叠，激光传感器根据滤波反射层透过的第二频段的光线确定距离，镜片组件根据距离调焦，其中，第一频段和第二频段相互独立。
根据本申请实施例提供的摄像头模组，包括反射件以及设于反射件一侧的镜片组件和图像传感器，通过在反光透光面上设置滤波反射层，并在反光透光面远离进光面的一侧设置激光传感器，一方面通过将激光传感器设于摄像头的内部，可有效解决现有技术中设置激光传感器所需要的额外空间，另一方面还可由于激光传感器和图像传感器均通过反射件的光路接收外部光线，故而其视场角的重合角度较高，也即提高激光传感器和图像传感器中感光单元的视场角的重合程度，从而提高对焦点的精准度，更利于满足用户在使用摄像头模组进行拍摄时的对焦需求。
具体地，三棱镜包括有进光面、反光透光面和出光面三个棱面，光线在三棱镜内传播时，主要是由进光面射入，并在反光透光面的反射下经出光面向外射出实现的，可以理解，通过设置三棱镜，可改变光线的传播方向，在特定方向上的尺寸受限时，通过更改光路方向可在另一方向上实现光路的完整，特别是，用于潜望式摄像头，可根据需求起到调整焦段的效果。此外，在三棱镜的一侧设置由镜片组件和图像传感器，经出光面向外射出的光线主要是射向图像传感器，以便于图像传感器接收光线实现成像。
需要强调的是，本申请主要通过增设滤波反射层和激光传感器实现的，滤波反射层直接设置在反光透光面上，在滤波反射层的作用下，可将第一频段的光线进行反射，并将第二频段的光线进行过滤，需要说明的，对于第二频段的光线进行过滤，为仅有第二频段的光线可以穿过滤波反射层，而对其他频段的光线进行滤除。
此外，通过在反光透光面远离进光面的一侧设置激光传感器，并在激光传感器的安装面上，滤波反射层覆盖激光传感器，也即滤波反射层的投影与激光传感器至少部分重叠，可使得激光传感器向外发射的光线均能通过滤波反射镜结构射入三棱镜中，以便于实现提高激光传感器和图像传感器中感光单元的视场角的重合程度，以降低对焦的偏离。在摄像头模组工作时，激光传感器可根据第二频段的光线确定距离，镜片组件则可根据距离进行调焦操作。
其中，第一频段和第二频段相互独立，也即第一频段与第二频段之间无重合部分。
本领域技术人员可以理解，在开始对焦时，激光传感器会发出特定频段的光线，包括但不限于红外激光束，此时开始计时，再通过激光传感器接收到经拍摄物体或是障碍物反射回来的光线，此时停止计时，通过对光速和时间的计算，即可得到摄像头模组与障碍物之间的距离，此时可将距离发送给摄像头模组中的对焦控制器，以控制对焦马达运转到焦平面以实现对焦。
第二方面，本申请实施例提出了一种电子设备，包括：本体；上述实施例中的摄像头模组，设于本体上，其中，摄像头模组为电子设备的前置摄像模组和/或后置摄像模组。
根据本申请实施例提供的电子设备，包括本体和上述任一实施例的摄像头模组，通过将摄像头模组设置在本体上，可将摄像头模组所成的像发送至本体上，以便于后续的二次编辑和分享，其中，摄像头模组可以为前置模组，还可以为后置模组，从而使得电子设备的前摄像头具有防抖功能，或是后摄像头具有防抖功能，还可以地，前后双摄像头均具有上述任一实施例的防抖功能。
由于电子设备包括上述任一实施例的摄像头模组，故而具有上述任一实施例的摄像头模组的有益效果，在此不在赘述。
值得说明的是，电子设备的种类是多样的，比如：手机、平板电脑、电子阅读器等需要摄像头模组的设备。

下面结合图3至图9描述根据本申请实施例的摄像头模组和电子设备。
如图3和图4所示，本申请提供了一种摄像头模组100的实施例，包 括：反射件，反射件上设有反光透光面；镜片组件104和图像传感器106，设于反射件102的一侧，经出光面1026向外射出的光线经镜片组件104射入图像传感器106；滤波反射层108，设于反光透光面1024上，滤波反射层108能够反射第一频段的光线，且滤波反射层108能够透过第二频段的光线；激光传感器110，设于反光透光面1024远离进光面1022的一侧，且在激光传感器110的安装面上，滤波反射层108的投影覆盖激光传感器110，其中，第一频段和第二频段相互独立。
根据本申请实施例提供的摄像头模组100，包括反射件102以及设于反射件102一侧的镜片组件104和图像传感器106，通过在反光透光面1024上设置滤波反射层108，并在反光透光面1024远离进光面1022的一侧设置激光传感器110，一方面通过将激光传感器110设于摄像头的内部，可有效解决现有技术中设置激光传感器110所需要的额外空间，另一方面还可由于激光传感器110和图像传感器106均通过反射件102的光路接收外部光线，故而其视场角的重合角度较高，也即提高激光传感器110和图像传感器106中感光单元的视场角的重合程度，从而提高对焦点的精准度，更利于满足用户在使用摄像头模组100进行拍摄时的对焦需求。在摄像头模组工作时，激光传感器可根据第二频段的光线确定距离，镜片组件则可根据距离进行调焦操作。
具体地，反射件102可以为三棱镜，主要包括有进光面1022、反光透光面1024和出光面1026三个棱面，光线在反射件102内传播时，主要是由进光面1022射入，并在反光透光面1024的反射下经出光面1026向外射出实现的，可以理解，通过设置反射件102，可改变光线的传播方向，在特定方向上的尺寸受限时，通过更改光路方向可在另一方向上实现光路的完整，特别是，用于潜望式摄像头，可根据需求起到调整焦段的效果。此外，在反射件102的一侧设置由镜片组件104和图像传感器106，经出光面1026向外射出的光线主要是射向图像传感器106，以便于图像传感器106 接收光线实现成像。
需要强调的是，本申请主要通过增设滤波反射层108和激光传感器110实现的，滤波反射层108直接设置在反光透光面1024上，在滤波反射层108的作用下，可将第一频段的光线进行反射，并将第二频段的光线进行过滤，需要说明的，对于第二频段的光线进行过滤，为仅有第二频段的光线可以穿过滤波反射层108，而对其他频段的光线进行滤除。
此外，通过在反光透光面1024远离进光面1022的一侧设置激光传感器110，并在激光传感器110的安装面上，滤波反射层108覆盖激光传感器110，可使得激光传感器110向外发射的光线均能通过滤波反射镜结构射入反射件102中，以便于实现提高激光传感器110和图像传感器106中感光单元的视场角的重合程度，以降低对焦的偏离。
对于本实施例而言，该摄像头模组100可以像原潜望式长焦摄像头一样正常成像，因为滤波反射层108没有改变潜望式反射件102的可见光反射的特性，同时它还能实现激光测距，从而辅助摄像头对焦，因为在滤波反射层108的作用下，激光传感器110发出的红外光可以正常透过，基于红外激光的激光传感器110不受摄像头棱角的阻挡。同时由于成像传感器和激光传感器110都是通过反射件102的光路来接收外部的光线，它们的FOV视角(即视场角)完全重合，也就解决了对焦偏偏移的问题。
其中，第一频段和第二频段相互独立，也即第一频段与第二频段之间无重合部分。
本领域技术人员可以理解，在开始对焦时，激光传感器110会发出特定频段的光线，包括但不限于红外激光束，此时开始计时，再通过激光传感器110接收到经拍摄物体或是障碍物反射回来的光线，此时停止计时，通过对光速和时间的计算，即可得到摄像头模组100与障碍物之间的距离，此时可将距离发送给摄像头模组100中的对焦控制器，以控制对焦马达运转到焦平面以实现对焦。
在一个实施例中，滤波反射层的透过率和反射率曲线如图7所示，可知第一频段为可见光频段，第二频段为红外光频段。
通过限制第一频段为可见光频段，第二频段为红外光频段，可使得在滤波反射层108的作用下，可完全反射可见光，完全透过红外光，以满足激光传感器110对红外光的探测需求，而由于对可见光完全反射，还可满足成像传感器的成像需求。
本领域技术人员应当了解，可见光频段为380nm～700nm，红外光频段为760nm～1mm。
如图6所示，滤波反射层的透过率和反射率曲线如图8所示，第一频段为红外光频段，第二频段为可见光频段，反射件102包括第一镜体1028和第二镜体1029，第一镜体1028的出光面1026与第二镜体1029的进光面1022相对设置，滤波反射层108设于第二镜体1029的反光透光面1024上，其中，外部光线经第一镜体1028的进光面1022、反光透光面1024和出光面1026射入第二镜体1029，且外部光线经第二镜体1029的进光面1022、反光透光面1024和滤波反射层108射向图像传感器106，测距光线依次经第二镜体1029的出光面1026、反光透光面1024、滤波反射层108和进光面1022射入第一镜体1028，且测距光线依次经第一镜体1028的出光面1026、反光透光面1024和进光面1022向外射出。
在另一个实施例中，通过限制第一频段为红外光频段，第二频段为可见光频段，可使得在滤波反射层108的作用下，可完全透过可见光，完全反射红外光，此时，反射件102包括两个镜体，一个镜体的出光面1026和另一个镜体的进光面1022相对设置，在第二镜体1029的反光透光面1024上设有滤波反射层108，此时，光线在传播时，会通过两个镜体射向成像传感器和激光传感器110，其中，由于滤波反射层108的作用为透过可见光，反射红外光，故而在滤波反射层108的作用下，经过第一镜体1028的出光面1026的光线由第二镜体1029的进光面1022射向第二镜体1029的 反光透光面1024时，若是测距光线，则会将红外光反射至激光传感器110，而正常的可见光则直接透过反光透光面1024直射入成像传感器中。
进一步地，外部光线为可见光，其传播路径为经第一镜体1028的进光面1022、反光透光面1024和出光面1026射入第二镜体1029，且外部光线经第二镜体1029的进光面1022、反光透光面1024和滤波反射层108射向图像传感器106。而测距光线为红外光，其传播路径为依次经第二镜体1029的出光面1026、反光透光面1024、滤波反射层108和进光面1022射入第一镜体1028，且测距光线依次经第一镜体1028的出光面1026、反光透光面1024和进光面1022向外射出。
滤波反射层108为二向色镜滤波片；或滤波反射层108为干涉滤波光学镀层。
在一个实施例中，滤波反射层108为二向色镜滤波片，采用成熟的二向色镜滤波片，通过光学胶水贴合在反射件102的反光透光面1024上，加工工序较为简便。
而在另一个实施例中，通过采用干涉滤波光学镀层来实现二向色镜，通过多层的干涉滤波技术，可以实现类似二向色镜的可见光反射、红外光透射的特性。本实施方式相较于直接采用滤波片的方案，集成度更高。
如图5所示，激光传感器110包括：信号发射器1102，信号发射器1102用于向外发出测距光线，测距光线经滤波反射层108和反射件102向外射出；信号接收器1104，信号接收器1104用于接收测距光线经障碍物反射后射入信号接收器1104的测距光线。
激光传感器110主要包括信号发射器1102和信号接收器1104，信号发射器1102可向外发出测距光线，以便于在开始对焦时发出特定频段的光线，包括但不限于红外激光束，测距光线依次经过滤波反射层108和反射件102后向外射出，此时开始计时，通过信号接收器1104接收到经拍摄物体或是障碍物反射回来的测距光线，此时停止计时，通过对光速和时间的计算， 即可得到摄像头模组100与障碍物之间的距离，此时可将距离发送给摄像头模组100中的对焦控制器，以控制对焦马达运转到焦平面以实现对焦。
进一步地，包括有壳体114，反射件102、镜片组件104、图像传感器106、滤波反射层108和激光传感器110设于壳体114内，且壳体114的一个壁面上设有与反射件102对应的进光孔1142，外部光线能够由进光孔1142射入反射件102。
摄像头模组100包括有容纳其他器件的壳体114，具体地，壳体114可容纳反射件102、镜片组件104、图像传感器106、滤波反射层108和激光传感器110，从而实现对反射件102、镜片组件104、图像传感器106、滤波反射层108和激光传感器110的保护，此外，在壳体114的壁面上设有与反射件102相对应的进光孔1142，也即取景孔，光线可经进光孔1142射入反射件102，从而分别射向激光传感器110和图像传感器106，以便于激光传感器110的测距和对焦，以及便于图像传感器106的取景和成像。
进一步地，还包括：软排线112，设于壳体114的内侧，且软排线112分别与图像传感器106和激光传感器110电连接。
通过在壳体114的内测设置软排线112，一方面可将图像传感器106形成的图像和激光传感器110测得的影像信息向主控板发送，也即形成图像传感器106、激光传感器110分别与主控板的电连接，以实现快速自动对焦的功能，另一方面，软排线112设于壳体114的内侧，还可通过其将图像传感器106和激光传感器110固定在壳体114上，以保证两个传感器的稳固。
进一步地，软排线112即为FPC排线，可通过较为成熟的FPC排线连接工艺，将两个传感器进行固定。
进光面1022与出光面1026相垂直，射入反射件102的光线能够在反光透光面1024的作用下垂直射向出光面1026，进光面1022与壳体114的进光孔1142的端面相平行。
对于反射件102而言，三个棱面相互之间可以为任意角度，而在本实施例中，为了更好的成像，将进光面1022和出光面1026做垂直处理，并限制进光面1022和进光孔1142的端面相平行，从而光路在传播的过程中，光线进入反射件102时是垂直进光面1022进入的，而经出光面1026射向图像传感器106时，由于通过限制光线在反光透光面1024的作用下射向出光面1026，也为垂直射出，以使得在反光透光面1024的作用下实现光路的变化，进而满足对于不同的成像和空间需求。
本领域技术人员可以理解，在进光面1022和出光面1026相垂直的基础上，若是限定射向出光面1026的光线为垂直射出，则反光透光面1024与进光面1022或出光面1026所成的角度为45度。
镜片组件104包括多个透镜1042，多个所述透镜1042的光轴共线。
在本实施例中，镜片组件104包括多个光轴共线的透镜1042，透镜1042的数量为多个，以便于在多个透镜1042的作用下调整成像传感器的成像焦距，以实现不同倍数的光学变焦，可以理解，多个透镜1042的种类包括但不限于平面镜、凹面镜、凸面镜等。
本申请的另一实施例提出了一种电子设备200，包括：本体210；上述实施例中的摄像头模组100，设于本体210上，其中，摄像头模组100为电子设备200的前置摄像模组和/或后置摄像模组。
根据本申请实施例提供的电子设备200，包括本体210和上述任一实施例的摄像头模组100，通过将摄像头模组100设置在本体210上，可将摄像头模组100所成的像发送至本体210上，以便于后续的二次编辑和分享，其中，摄像头模组100可以为前置模组，还可以为后置模组，从而使得电子设备200的前摄像头具有防抖功能，或是后摄像头具有防抖功能，还可以地，前后双摄像头均具有上述任一实施例的防抖功能。
由于电子设备200包括上述任一实施例的摄像头模组100，故而具有上述任一实施例的摄像头模组100的有益效果，在此不在赘述。
值得说明的是，电子设备200的种类是多样的，比如：手机、平板电脑、电子阅读器等需要摄像头模组的设备。
根据本申请实施例的摄像头模组和电子设备，在图像传感器内同时集成了感光单元和对焦单元，一方面可有效解决现有技术中设置激光传感器所需要的额外空间，另一方面还可提高激光传感器和图像传感器中感光单元的视场角的重合程度，从而提高对焦点的精准度，更利于用户在使用摄像头模组进行拍摄时的对焦需求。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本申请的实施例，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
