 附图说明
为了更清楚地说明本发明实施方式中的技术方案，下面将对实施方式描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施方式，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图，其中：

 本发明的最佳实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明的各实施方式进行详细的阐述。然而，本领域的普通技术人员可以理解，在本发明各实施方式中，为了使读者更好地理解本发明而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施方式的种种变化和修改，也可以实现本发明所要求保护的技术方案。
参考图1-图5， 本发明提供了一种镜头模组100，包括镜头10、收容镜头10的外壳20、固定于外壳的传感器40和线路板30。镜头10包括镜筒19和收容于镜筒19内的多个镜片13，每个镜片13包括用于成像的成像部132和设于成像部132的外侧用于组装的安装部131，多个镜片13中包括靠近成像面Si设置的两个减光镜片14，减光镜片14包括一个平行于光轴OO’的减光切面141，减光切面141到光轴OO’的垂直距离小于成像部132的半径，镜筒19包括远离成像面Si的天面11和自天面11弯折延伸的侧壁12，侧壁12包括平行于减光切面141的平面壁121，减光切面141和平面壁121相对设置。与现有技术相比，通过设置减光切面141和平面壁121，减小了镜头模组100沿光轴OO’方向的投影面积，也就是减小了镜头模组100的底部尺寸，可以将镜头模组100更靠近电子设备1的边框排布，至少一部分入瞳可以排布在屏幕的非显示区3内，减小镜头开孔5在显示区4中的占用面积，换句话说，由于镜头开孔5需要跟镜头入瞳对应设置，也就是说镜头入瞳决定了镜头开孔在屏幕上的位置，由于镜头模组的底部尺寸在一侧缩小，使得入瞳更靠近边框，镜头开孔5也随之更靠近边框，有利于实现电子设备的全面屏设计。在其他实施方式中，减光镜片的数量可以按需要增减，至少要包括一个减光镜片，如果只包含一个减光镜片，则该减光镜片设置于最靠近成像面的一侧效果最佳。
本实施方式中，镜头模组100在不同方向可以具有不同的成像高度和成像范围，在减光切面一侧的减光像高IH2小于与之相对的正常像高IH1，镜头10的成像范围IA1由一个成像圆弧IA12和一个成像切边IA11规定，传感器40完全设于镜头10的成像范围IA1内，传感器40呈矩形，形状可以为4:3或者16:9等，成像切边IA11与传感器短边之间可以设置间隔，使得一定的组装偏移量不影响传感器成像，传感器形成的图像形状与传感器形状相同，镜头10的头部直径LOD1小于传感器的短边边长。
本实施方式中，外壳20具有平行于天面11的顶面21和自顶面21弯折延伸的侧面22，顶面21呈矩形且具有开口211，开口211由一个开口圆弧212和一个开口切边213构成，镜头10的入瞳直径ENPD位于开口211的内侧，开口切边213平行于平面壁121，侧面22包括平行于开口切边213的两个第一侧面221和与第一侧面221连接的两个第二侧面222。
电子设备1，包括屏幕9、镜头模组100和边框2，屏幕9包括显示区4和设于显示区4的外侧的非显示区3，屏幕9还包括与镜头模组100相对的镜头开孔5，镜头开孔5位于屏幕9的一个侧边，镜头开孔5的至少一部分位于非显示区3，减小显示区4内的屏幕开口。在其他可选的实施方式中，镜头开孔可以完全位于非显示区内，从而实现电子设备的全面屏。
本实施方式中，镜片13还包括四个个切边镜片15，切边镜片15设于减光镜片14的物侧，切边镜片14包括一个平行于光轴OO’的组装切面151，组装切面151到光轴OO’的垂直距离小于安装部131的半径且大于成像部132的半径，即，镜片13除了靠近像侧设置的两片镜片为减光镜片，其余镜片均为切边镜片，在缩小体积的同时合理地保留镜头的光学性能；组装切面151平行于减光切面141，或者，组装切面151与减光切面141共面，两类切面在镜头的同一侧且角度相同可以最大程度的减小镜头的整体体积。在其他实施方式中，根据镜头设计的不同镜片尺寸和不同体积或光学性能要求，减光镜片的数量是可以调整的，至少有一个减光镜片即可；同样的，切边镜片的数量也可以调整，甚至可以不设置切边镜片；为了达到特殊的光学要求，例如为了消除杂散光，减光切面和组装切面可以不共面，也可以不平行，在垂直于光轴的平面内呈角度交叉设置，利用不同的结构设计达到消除杂散光的效果。
在本实施方式中，只有一个平面壁121，并且平面壁121延伸至天面11，也就是说一个平面壁121直接与天面相互连接，这种设计不仅是体积最小化的最优解，同时也可以降低许多工序的生产难度，提高生产良率，例如，延伸至天面的平面壁使得取放更容易。在其他实施方式中，根据减光镜片和切边镜片的数量的调整，平面壁可以分段与减光切面或组装切面相对设置，也可以设置为台阶状以与台阶状的镜片边缘对应。例如，从物侧起第一片镜片既不是减光镜片也不是切边镜片时，其所对应的镜筒外侧面为一整圈的圆筒状，从物侧起第二片镜片为切边镜片或减光镜片，其所对应的镜筒外侧面为平面壁，此时，平面壁与天面之间存在间隔，间隔了一段圆筒壁。
参照图6-8，为本发明的另一种实施方式，以下只简述与上述实施方式的区别点。本实施方式中，镜头模组100’中镜头10’沿B-B方向的剖面图和沿C-C方向的剖面图均与图2类似，因此没有重复作图，可以结合图2理解。
本实施方式中，减光镜片14包括两个相互垂直的减光切面141，切边镜片15包括两个组装切面151，镜筒19’包括两个平面壁121，两个组装切面151与两个减光切面141一一对应。
外壳20’的开口211’具有两个相互垂直的开口切边213，侧壁12包括两个相互垂直的平面壁121，镜头的成像范围IA2由两个相互垂直的成像切边IA21和一个成像圆弧IA22规定，传感器41完全设于镜头10的成像范围IA2内，传感器41呈矩形，形状可以为4:3或者16:9等，成像切边IA21与传感器短边之间可以设置间隔，使得一定的组装偏移量不影响传感器成像，传感器形成的图像形状与传感器形状相同，镜头10的头部直径LOD2小于传感器41的短边边长。
在本实施方式中，两个开口切边213长度相等， 两个平面壁均延伸至天面，两个减光切面141距离光轴OO’的垂直距离相等，两个组装切面151距离光轴OO’的垂直距离也相等，使得形状规则，易于评价光学性能，在其他实施方式中，两个开口切边也可以具有不同的长度，两个减光切面距离光轴的垂直距离可以不相等，两个组装切面距离光轴的垂直距离也可以不相等。
本实施方式中，镜头模组100’的底部尺寸在两个方向都有缩小，入瞳向对角方向向边框移动，电子设备1’的镜头开孔5’位于屏幕9’的一个角部，充分利用镜头模组底部尺寸减小带来的镜头入瞳在对角线方向的偏移，镜头开孔5’全部位于非显示区3，消除了显示区4内的屏幕开口。在其他可选的实施方式中，镜头开孔可以部分位于非显示区内，显示区内仅需设置一个扇形开口。
以上的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
