Description
本申请涉及光学镜头技术领域，尤其涉及一种镜头组件及电子装置。
近年来，随着科技的不断发展，电子装置不断地朝着智能化发展，除了数码相机外，便携式电子装置例如平板电脑、手机等也都配备了镜头组件。
现有技术中镜头组件一般包括镜头筒和收容于镜头筒内的镜片组，镜片组完全隐藏在镜头筒的内部。在电子装置上安装镜头组件时，基本都是使用镜头筒的像侧端面作为整个镜头组件的承靠基准，但是镜头筒一般是通过注塑形成，其端面的平整度不是很高，以镜头筒的像侧端面作为承靠基准时，不仅会导致承靠不稳定，而且容易发生镜头筒与电子装置的其他部件相干涉的现象。
本申请的目的在于提供一种镜头组件及电子装置，能够提高镜头组件的承靠平稳性，而且能够避免镜头筒与电子装置上的其他部件相干涉。
本申请的技术方案如下：
一种镜头组件，包括镜头筒和第一镜片，所述第一镜片包括本体和承靠部，所述本体连接于所述镜头筒的内壁，所述承靠部位于所述本体的像侧面上，所述承靠部的像侧面包括承靠面，且所述承靠面露出所述镜头筒的像侧端面外。
进一步的，所述承靠面为平面，且所述承靠面与所述镜头组件的光轴相垂直。
进一步的，所述承靠面为环状，且所述承靠面的圆心在所述镜头组件的光轴上。
进一步的，所述承靠部的数目为多个，多个所述承靠部环绕所述镜头组件的光轴间隔设置，且多个所述承靠部的所述承靠面共面。
进一步的，所述本体包括第一光学部和围绕所述第一光学部的第一周边部，所述第一周边部与所述镜头筒的内壁连接，所述承靠部位于所述第一周边部上。
进一步的，所述承靠部与所述本体一体成型。
进一步的，所述镜头组件包括点胶槽，所述点胶槽的内壁包括第一内壁和第一侧壁，所述第一内壁设置于所述镜头筒的内侧，所述第一侧壁设置于所述承靠部上。
进一步的，所述第一内壁沿物侧至像侧朝远离所述镜头组件的光轴的方向倾斜，所述第一侧壁的倾斜方向与所述倾斜面的倾斜方向相反。
一种电子装置，包括上述的镜头组件，还包括用于安装所述镜头组件的安装部，所述承靠面与所述安装部相贴合，所述镜头筒的像侧端面与所述安装部之间具有间隙。
本申请的有益效果在于：本申请在第一镜片的像侧设置凸起的承靠部，并使承靠部凸出镜头筒的像侧端面外，在电子装置上安装镜头组件时，承靠部的承靠面能够代替现有技术中镜头筒的像侧端面而作为承靠基准，在安装镜头组件时，能够保证镜头组件的承靠稳定性和安装精准度，且镜头筒与电子装置的安装部之间具有间隙，可避免镜头筒与电子装置的安装部之间发生干涉。
