另外，第二镜片27的周边部的像侧面包括与第一凹槽26相同的第四凹槽；第三镜片28的周边部的结构与第二镜片27的周边部的结构相同或者不同。进一步地，镜片组还包括位于第三镜片28像侧的第四镜片29，不限于此，上述示例仅用于说明。
实施例2
本实用新型还提供了一种镜头模组，该镜头模组与实施例1的区别在于，镜片组2至少包括与遮光板4相配合的镜片，该镜片位于遮光板4的物侧，在本实施方式中，如图1、图6和图7所示，该镜片为第三镜片28,第三镜片28的周边部的物侧面包括与第一凸起部25相同的第三凸起部33，第三凸起部33的数量为三个，三个第二凸起部33沿第三镜片28的圆周等间隔设置；第三镜片28的周边部的像侧面包括第二凹槽34沿第三镜片28的圆周均匀分布的至少两个第二凹槽34，多个第二凹槽34优选等间隔设置，第二凹槽34与第一凹槽26相同。具体地，第二凹槽34包括第二槽底面、与第二槽底面相连且自第二槽底面向所述遮光板倾斜延伸的第三侧壁和第四侧壁；第二凹槽34的槽宽自像侧向物侧逐渐减小。
如图8所示，遮光板4为环状构件，遮光板4包括收容固定于第二凹槽34的第四凸起部40，第四凸起部40自遮光板4的物侧面向第三镜片28（第一筒壁11）凸出，第四凸起部40收容固定于第二凹槽34，第四凸起部40的数量与第二凹槽34的数量相等。
在本实施方式中，第二凹槽34包括第二槽底面341、与第二槽底面341相连且自第二槽底面341向遮光板4倾斜延伸的第三侧壁342和第四侧壁343；第二凹槽34的槽宽自像侧向物侧逐渐减小。
在本实施方式中，第四凸起部40的数量为三个，第四凸起部40的数量与第二凹槽34的数量相等；三个第四凸起部40沿遮光板4的圆周等间隔设置；第三凸起部33和第四凸起部40的结构相同，因此省略了对第三凸起部33的说明。
进一步地，第四凸起部40包括靠近物侧的第四侧面41及位于第四侧面41两侧的第五侧面42和第六侧面43，第四侧面41与第二槽底面341间隔设置，第五侧面42与所述第三侧壁342相贴合，第六侧面43与第四侧壁343相贴合；第四凸起部34还包括靠近光轴X的第三端面和靠近第二筒壁12的第四端面，第三端面与第二凹槽34的对应侧面间隔设置，第四端面与第二筒壁12的内壁面相贴合。
在上述结构中，三个第一凸起部25将第二镜片27均匀分隔成三部分再与第一镜片21的第一凹槽26相配合，使第一镜片21与第二镜片27之间的承靠更加平整，既保证了镜片的外径精度，还确保了镜片与镜片的配合精度，提升了镜头的稳定性。同样地，三个第四凸起部40将遮光板4均匀分隔成三部分再与第三镜片28的第二凹槽34相配合，使第三镜片28与遮光板4之间的承靠更加平整，既保证了镜片的外径精度，还确保了镜片与镜遮光板的配合精度，提升了镜头的稳定性。
另外，镜片组2还包括位于第三镜片28像侧的第四镜片29，镜片数量不仅限于此。另外，在镜片之间可以设遮光件，但该遮光件也可以省略。
与现有技术相比，本实用新型镜头模组可以保证各组件的外径精度，而且镜片与镜头筒之间、镜片与镜片之间、镜片与遮光板之间的相互配合更精确，提高了镜头的稳定性；配合精度高，配合更稳定，提高了镜头的整体性能。
以上所述的仅是本实用新型的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本实用新型创造构思的前提下，还可以做出改进，但这些均属于本实用新型的保护范围。
