技术领域
本申请涉及电子设备领域，尤其是涉及一种摄像头组件及具有其的电子设备。
背景技术
虹膜识别技术应用越来越广泛，例如手机等电子设备具有虹膜识别功能，可以实现虹膜解锁。虹膜解锁时需要人眼对着摄像头，红外灯发射的红外光也要照到人眼上，由于红外灯和摄像头之间有一定的距离，红外灯的光线实际上是偏离人眼的，这样人眼接受到的红外光就较弱，摄像头捕捉的红外光不足就容易导致解锁失败。
发明内容
本申请旨在至少解决现有技术中存在的技术问题之一。为此，本申请提出一种电子设备的摄像头组件，所述摄像头组件可以实现红外灯光线的任意角度偏转，成本低、通用性强。
本申请还提出了一种具有上述摄像头组件的电子设备。
根据本申请第一方面实施例的电子设备的摄像头组件，包括：相互平行且间隔开设置的主板和盖板；摄像头和红外灯，所述摄像头和所述红外灯设在所述主板朝向所述盖板的一侧；用于将所述红外灯发射的光线朝向所述摄像头的中心轴线所在方向偏转的偏转件，所述偏转件设在所述盖板朝向所述主板的一侧，所述偏转件与所述摄像头相对设置。
根据本申请实施例的电子设备的摄像头组件，通过在摄像头的正面加设偏转件，红外灯产生的光线在经过虹膜反射之后，形成的反射光经过偏转件发生偏转，然后垂直照射到摄像头，使得摄像头可以捕捉到更多的红外光线，从而可以实现解锁，防止解锁失败，并且可以根据偏转角度的需要设置具有不同偏转角度的偏转件，由于不需要另外特别定制红外灯，由此可以降低成本，还可以实现红外灯的共通化。
根据本申请第二方面实施例的电子设备，包括：根据本申请上述第一方面实施例的摄像头组件。由此，可以防止虹膜解锁失败，并可以降低成本。

下面参考图2-图5描述根据本申请实施例的电子设备的摄像头组件。
如图2-图5所示，根据本申请第一方面实施例的电子设备的摄像头组件，包括：主板1、盖板2、摄像头4、红外灯5和偏转件6。
具体而言，主板1和盖板2相互平行且间隔开设置，盖板2可以为纯平触摸屏盖板，盖板2可以采用玻璃材质制成。摄像头4和红外灯5设在主板1朝向盖板2的一侧，摄像头4和红外灯5之间间隔一定的距离(参照图3-图5中的距离L)，摄像头4为虹膜摄像头。需要在此说明的是，本申请的红外灯5是普通的红外灯，不需要特别定制，不具有偏转功能，因此本申请的红外灯5制造周期短、制造成本低。
偏转件6用于将红外灯5发射的光线朝向摄像头4的中心轴线所在方向偏转，偏转件6设在盖板2朝向主板1的一侧，偏转件6与摄像头4相对设置。由此，在将该摄像头组件应用于电子设备1000例如手机时，需要通过虹膜对手机进行解锁，此时人眼2000可以对着红外灯5，红外灯5发射的红外光直接照射到人眼2000内，照射人眼的红外光反射至偏转件6上，经过偏转件6偏转一定的角度后被摄像头4捕捉，通过设置的偏转件6可以将红外灯5的光线垂直照射到摄像头4，使得摄像头4可以捕捉到更多的红外光线，实现解锁。
本申请中的偏转件6可以根据需要设计成不同的偏转角度，从而可以实现红外灯5光线的任意角度偏转，对整机的堆叠有很大的改善，堆叠时可以不用考虑红外光的偏转角度问题，可以任意改变红外灯5和摄像头4之间的距离L。另外，由于不需要特别定制红外灯5，可以减少定制红外灯5的成本，还可以实现红外灯5的共通化。
本申请中的摄像头组件，通过在摄像头4的正面加设偏转件6的方式，可以实现任意角度偏转，当摄像头4和红外灯5在手机等电子设备1000上的位置发生变化时，只需要重新做个偏转件6，加工周期短且成本低，对整个项目的进度影响甚微。
根据本申请实施例的电子设备的摄像头组件，通过在摄像头4的正面加设偏转件6，红外灯5产生的光线在经过虹膜反射之后，形成的反射光经过偏转件6发生偏转，然后垂直照射到摄像头4，使得摄像头4可以捕捉到更多的红外光线，从而可以实现解锁，防止解锁失败，并且可以根据偏转角度的需要设置具有不同偏转角度的偏转件6，由于不需要另外特别定制红外灯5，由此可以降低成本，还可以实现红外灯5的共通化。
在本申请的一些实施例中，在由摄像头4至红外灯5(参照图3-图5中的e1方向)的方向上，偏转件6的尺寸大于摄像头4的尺寸。由此，可以保证红外灯5发射的红外光线 通过偏转件6进行偏转后均垂直照射至摄像头4，从而使得摄像头4可以捕捉到更多的红外光线。
可选地，偏转件6可以通过粘胶层3连接在盖板2上。由此，可以方便偏转件6的安装固定。例如，偏转件6可以通过双面胶、点胶等方式固定在盖板2上。
可选地，偏转件6可以为PMMA(polymethyl methacrylate，聚甲基丙烯酸甲酯)件、PC(Polycarbonate，聚碳酸酯)件等。由此，可以降低成本，进一步地缩短加工周期，加工成型周期一般只需要一周左右时间，因而对整个项目的进度影响甚微。
在本申请的一些实施例中，在由摄像头4至盖板2(参照图3-图5中的e2方向)的方向上，偏转件6具有相对的第一表面61和第二表面62，第一表面61邻近摄像头4且第二表面62远离摄像头4，第一表面61和第二表面62互成角度。此时偏转件6可以设置成相当于三棱镜的结构，由此红外灯5发射光线直接照射人眼2000，而后反射至偏转件6，经过该偏转件6时可以按照需要发生偏转，且该偏转件6的结构简单、易于制造。可选地，该偏转件6的截面(所述“偏转件6的截面”是指红外灯5的光轴与摄像头4的光轴所在的平面截该偏转件6所得的平面图形)形状可以为三角形、梯形等。
根据本申请的一些实施例，红外灯5发射的红外光的波长为940nm。其中，波长的公差范围可以为±20nm。940nm的红外光在对虹膜成像提供有效光源的同时不被人眼2000可见，用户体验更佳，且940nm的红外光对于黑色虹膜的识别效果更佳。由此，红外灯5可以针对特定的亚洲人群使用，提高了使用舒适度和识别效率。
下面参照图2-图5描述根据本申请多个实施例的摄像头组件。
实施例一，
参照图2和图3，在本实施例中，摄像头组件包括上述的主板1、盖板2、摄像头4、红外灯5和偏转件6。其中，在由摄像头4至红外灯5的方向上，第一表面61朝向摄像头4倾斜，可以通过改变第一表面61的倾斜角度α，调整偏转件6的偏转角度；第二平面平行于盖板2。此时，该偏转件6可以看成是在由摄像头4至红外灯5的方向上，其厚度(所述“厚度”是指偏转件6在由摄像头4至盖板2方向上的尺寸)增大。人眼2000对着红外灯5，红外灯5发射光线直接照射人眼2000，而后反射至偏转件6，光线通过该偏转件6进行偏转时，光线朝向偏转件6厚度大的方向偏转，使得红外光垂直照射摄像头4，从而使得摄像头4可以捕捉到更多的红外光线，实现解锁。
可选地，上述第一表面61可以为平面结构。由此，易于加工成型。
可选地，上述第一表面61还可以为曲面结构，在由摄像头4至红外灯5的方向上，第一表面61上的每个点的切线朝向摄像头4倾斜。由此，可以保证红外光线垂直照射摄像头 4。
另外，由于偏转件6的第二表面62平行于盖板2，方便偏转件6安装固定在盖板2上。
实施例二，
参照图2和图4，在本实施例中，摄像头组件包括上述的主板1、盖板2、摄像头4、红外灯5和偏转件6。其中，第一表面61平行于盖板2；在由摄像头4至红外灯5的方向上，第二表面62朝向盖板2倾斜，可以通过改变第二表面62的倾斜角度α，调整偏转件6的偏转角度。此时，该偏转件6可以看成是在由摄像头4至红外灯5的方向上，其厚度(所述“厚度”是指偏转件6在由摄像头4至盖板2方向上的尺寸)增大。人眼2000对着红外灯5，红外灯5发射光线直接照射人眼2000，而后反射至偏转件6，光线通过该偏转件6进行偏转时，光线朝向偏转件6厚度大的方向偏转，使得红外光垂直照射摄像头4，从而使得摄像头4可以捕捉到更多的红外光线，实现解锁。
实施例三，
参照图2和图5，在本实施例中，摄像头组件包括上述的主板1、盖板2、摄像头4、红外灯5和偏转件6。其中，在由摄像头4至红外灯5的方向上，第一表面61朝向摄像头4倾斜；在由摄像头4至红外灯5的方向上，第二表面62朝向盖板2倾斜。可以通过改变第一表面61和第二表面62之间的夹角α，调整偏转件6的偏转角度。此时，该偏转件6可以看成是在由摄像头4至红外灯5的方向上，其厚度(所述“厚度”是指偏转件6在由摄像头4至盖板2方向上的尺寸)增大。人眼2000对着红外灯5，红外灯5发射光线直接照射人眼2000，而后反射至偏转件6，光线通过该偏转件6进行偏转时，光线朝向偏转件6厚度大的方向偏转，使得红外光垂直照射摄像头4，从而使得摄像头4可以捕捉到更多的红外光线，实现解锁。
根据本申请第二方面实施例的电子设备1000，包括：根据本申请上述第一方面实施例的摄像头组件。由此，可以防止虹膜解锁失败，并可以降低成本。
本申请中的电子设备1000可以为手机、平板电脑等移动终端。本申请中的摄像头4还可以用于家用防盗门等需要具备虹膜解锁功能的电子设备上。
参照图1，在上述电子设备1000为手机时，电子设备1000可以包括：壳体200、触摸屏盖板、摄像头4、射频电路、存储器、输入单元、无线保真(WiFi，wireless fidelity)模块、传感器、显示屏300、音频电路、处理器、指纹识别组件、电池等部件。其中，上述盖板2为手机的触摸屏盖板，主板1为手机的电路主板，手机中的摄像头包括上述的摄 像头组件的中的摄像头4，显示屏300位于盖板2内侧。
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。
