具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例方式作进一步地详细描述。
下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
第一方面，参见图1至9，本申请实施例提供了一种镜筒组件100。镜筒组件100包括第一镜筒110以及第二镜筒120。镜筒组件100并不局限于仅包括两个镜筒；如，镜筒组件100还可以包括第三镜筒、第四镜筒等。因相邻的两个镜筒之间的组装方式可以相似，因此，本申请实施例中仅以镜筒组件100包括第一镜筒110及第二镜筒120为例进行详细说明。
为使第一镜筒110相对于第二镜筒120绕第二镜筒120的光轴的转动调整能够实现各个镜片的相对调整，从而提升镜头组件10解析力，第一镜筒110以及第二镜筒120应当均可以安装镜片。即，参见图3，第一镜筒110限定出用于设置第一镜片组130的第一容纳腔111，第二镜筒120限定出用于设置第二镜片组140的第二容纳腔121。
为确保第一镜筒110相对于第二镜筒120的转动调整能够实现位于第一镜筒110内的第一镜片组130相对于安装于第二镜筒120内的第二镜片组140的调整，第一镜筒110可以与第一镜片组130通过点胶等方式固定，第二镜筒120可以与第二镜片组140通过点胶等方式固定。
当然，为使第一镜筒110与第二镜筒120相对调整的幅度不要太大，不会扩大相对调整时的工作量，第一镜筒110与第二镜筒120可以首先预定位连接，并在预定位连接的情况下实现可以相对调整。第一镜筒110与第二镜筒120的预定位连接可以通过任意方式实现。本申请实施例中给出了通过对第一镜筒110的像侧端以及对第二镜筒120的物侧端的结构改进来实现第一镜筒110与第二镜筒120的预定位连接。具体地，参见图3，第一镜筒110的像侧端的外壁面设置有第一定位凸缘112，第一定位凸缘112可以为第一镜筒110的像侧端的外壁面朝背离第一镜筒110的光轴的方向延伸形成。第二镜筒120的物侧端的内壁面设置有第二定位凸缘122，第二定位凸缘122可以为第二镜筒120的物侧端的内壁面朝靠近第二镜筒120的光轴的方向延伸形成。当然，为使第二定位凸缘122的设置不会影响光线进入到第二镜筒120，第二定位凸缘122的内部应当限定出与第二容纳腔121连通的通孔1221。
第一镜筒110的像侧端以及第二镜筒120的物侧端的结构通过上述改进后，参见图3，第一镜筒110可以配置成与第二镜筒120装配后，第一镜筒110的像侧端位于第二容纳腔121内、第一镜筒110的物侧端位于第二容纳腔121外且位于第二镜筒120的物侧，且第一定位凸缘112的物侧面与第二定位凸缘122的像侧面抵接，第一镜筒110可相对于第二镜筒120绕第二镜筒120的光轴转动。此时第一镜筒110以及第二镜筒120通过第一定位凸缘112的物侧面与第二定位凸缘122的像侧面的抵接实现预定位，使第一镜筒110相对于第二镜筒120可以在第一定位凸缘112与第二定位凸缘122相互抵靠的情况下实现一定范围内的转动调整。
为进一步提升镜头组件10的解析力，第一镜筒110除了可以相对于第二镜筒120绕第二镜筒120的光轴转动外，第一镜筒110还可以相对于第二镜筒120进行倾斜和平移的调整，从而实现包括第一镜筒110以及第二镜筒120的镜头组件10的偏心、倾斜或间隙的校准。
第一定位凸缘112的物侧面以及第二定位凸缘122的像侧面均可以为平面，且第一定位凸缘112的物侧面可以垂直于第一镜筒110的光轴，第二定位凸缘122的像侧面可以垂 直于第二镜筒120的光轴。当然，为使第一镜筒110相对于第二镜筒120转动的过程中，还能够实现第一镜筒110相对于第二镜筒120的倾斜调整，第一定位凸缘112的物侧面以及第二定位凸缘122的像侧面中可以有一个为非平面；或，第一定位凸缘112的物侧面为垂直于第一镜筒110的光轴的平面，第二定位凸缘122的像侧面为不垂直于第二镜筒120的光轴的平面；或，第一定位凸缘112的物侧面为不垂直于第一镜筒110的光轴的平面，第二定位凸缘122的像侧面为垂直于第二镜筒120的光轴的平面。
第一镜筒110的像侧端为第一镜筒110的靠近成像面的一端。具体地，第一镜筒110的像侧面与其物侧面之间可以具有第一参考面，第一镜筒110的像侧端可以为第一镜筒110的位于其像侧面与第一参考面之间的部分。需要说明的是，第一参考面可以为第一镜筒110上设置的某一台阶面等。当然，第一镜筒110上也可以不设置第一参考面，而将第一镜筒110沿某一方向的截面定义为第一参考面。第一镜筒110的物侧端为第一镜筒110的背离成像面的一端。具体地，第一镜筒110的像侧面与其物侧面之间可以具有第二参考面，第一镜筒110的物侧端可以为第一镜筒110的位于其物侧面与第二参考面之间的部分。第二参考面可以与第一参考面相同，第二参考面也可以位于第一参考面的物侧。需要说明的是，第二参考面可以为第一镜筒110上设置的某一台阶面等。当然，第一镜筒110上也可以不设置第二参考面，而将第一镜筒110沿某一方向的截面定义为第二参考面。
第二镜筒120的物侧端为第二镜筒120的背离成像面的一端。具体地，第二镜筒120的像侧面与其物侧面之间可以具有第三参考面，第二镜筒120的物侧端可以为第二镜筒120的位于其物侧面与第三参考面之间的部分。需要说明的是，第三参考面可以为第二镜筒120上设置的某一台阶面等。当然，第二镜筒120上也可以不设置第三参考面，而将第二镜筒120沿某一方向的截面定义为第三参考面。
为使第二定位凸缘122能够将第一定位凸缘112更为可靠的限定于第二容纳腔121内，参见图1至图4，沿垂直于第二镜筒120的光轴的方向，第二定位凸缘122的截面可以均呈圆环形。通过将沿垂直于第二镜筒120的光轴的方向，第二定位凸缘122的截面均设置为圆环形，能够使第二定位凸缘122在360°的方向上实现对第一定位凸缘112的限定，从而能够更好的避免第一定位凸缘112从第二容纳腔121中脱离。当然，因第二定位凸缘122的限定，第一镜筒110在与第二镜筒120装配时第一镜筒110的像侧端将不能从第二镜筒120的物侧进入第二容纳腔121，第一镜筒110应该满足能够从第二镜筒120的像侧进入第二容纳腔121，且第一镜筒110的物侧端可由第二容纳腔121内穿过通孔1221。
若将第一镜筒110从第二镜筒120的像侧进入第二容纳腔121，且最终第一镜筒110的物侧端位于第二容纳腔121外且位于第二镜筒120的物侧，则在第一镜筒110安装于第二容纳腔121之前，第二容纳腔121内应当没有安装第二镜片组140。这样包括第一镜片组130以及第一镜筒110的第一镜头10a的组装与包括第二镜片组140以及第二镜筒120的第二镜头10b的组装就无法独立进行，为解决上述问题，本申请实施例的镜头组件10的结构还可以满足第一镜筒110能够从第二镜筒120的物侧进入第二容纳腔121，从而使第一镜头10a与第二镜头10b能够独立组装完成之后再装配在一起。
具体地，参见图8至图13，沿垂直于第二镜筒120的光轴的方向，第二定位凸缘122的截面可以均呈圆环形，第二定位凸缘122具有背离第二镜筒120的物侧端的内壁面的第一表面1222，第一表面1222设置有第一凹槽1222a，且第一凹槽1222a贯穿第二定位凸缘122的物侧面以及第二定位凸缘122的像侧面，以使第一镜筒110能够配置成与第二镜筒120装配时，第一镜筒110的像侧端可从第二镜筒120的物侧穿过通孔1221、且位于第二容纳腔121内，且通过第一镜筒110与第二镜筒120的相对转动实现第一定位凸缘112的物侧面与第二定位凸缘122的像侧面的抵接。通过将第一镜筒110的像侧端从第二镜筒120的物侧进入第二容纳腔121，这样第一镜头10a、第二镜头10b就可以分别独立组装完成后再装配在一起，能够将第一镜头10a与第二镜头10b的组装工位分开，从而简化每个组装工位，降低对组装设备或组装工作人员的要求。同时，若第一镜头10a或第二镜头10b出现问题，第一镜头10a与第二镜头10b的拆装也更为方便。
为使第一镜筒110与第二镜筒120装配时，第一镜筒110的像侧端可从第二镜筒120的物侧穿过通孔1221，且位于第二容纳腔121内，参见图8至图13，沿垂直于第一镜筒110的光轴的方向，第一定位凸缘112的截面为第一截面，第一截面可以呈扇环形。沿垂直于第二镜筒120的光轴的方向，第一凹槽1222a的截面为第二截面，第二截面可以呈扇环形，且第一截面的圆心角为θ1，第二截面的圆心角为θ2，第一截面的外径为R1，第二截面的外径为R2，第二截面的内径为r2，θ1、θ2、R1、R2、r2满足以下关系式：
θ 1≤θ 2；r 2＜R 1≤R 2。通过上述设置后，第一镜筒110与第二镜筒120装配时，第一镜筒110的像侧端就可从第二镜筒120的物侧穿过通孔1221，可参见图8；且位于第二容纳腔121内，可参见图9。第一截面包括第一弧线、第二弧线、第一边线以及第二边线，第一弧线的半径大于第二弧线的半径，第一边线经过第一截面的圆心，且连接第一弧线的第一端以及第二弧线的第一端。第二边线经过第一截面的圆心，且连接第一弧线的第二端 以及第二弧线的第二端。第一截面的圆心角为第一边线与第二边线的夹角。第一截面的外径为第一弧线的半径。第二截面包括第三弧线、第四弧线、第三边线以及第四边线，第三弧线的半径大于第四弧线的半径，第三边线经过第二截面的圆心，且连接第三弧线的第一端以及第四弧线的第一端。第四边线经过第二截面的圆心，且连接第三弧线的第二端以及第四弧线的第二端。第二截面的圆心角为第三边线与第四边线的夹角。第二截面的外径为第三弧线的半径。第二截面的内径为第四弧线的半径。
同时针对图5示出的当第一镜筒110的外壁面的外径存在比第二镜筒120的内壁面的部分内径大时，第一镜筒110就不能从第二镜筒120的像侧进入第二容纳腔121，而可以采取将第一镜筒110从第二镜筒120的物侧进入第二容纳腔121。此时，为避免第一镜筒110的物侧面的开口较大，容易进入杂光，可以采取在第一镜筒110的物侧面设置遮光片；或，在第一镜筒110的物侧面另设置第三镜筒，且使第三镜筒的物侧面的开口较小。
为使第二定位凸缘122对第一定位凸缘112的限定更为可靠，可以减小第一凹槽1222a的圆心角，当然，若第一凹槽1222a的圆心角过小同样会造成第一定位凸缘112的圆心角过小，而第一定位凸缘112的圆心角过小会使第一定位凸缘112与第二定位凸缘122的抵接不再可靠，为使第一定位凸缘112与第二定位凸缘122的抵接可靠，且第二定位凸缘122对第一定位凸缘112的限定可靠，第一定位凸缘112的圆心角以及第一凹槽1222a的圆心角均可以为90°至180°。
当然，为使第二定位凸缘122对第一定位凸缘112的抵接可靠，第二定位凸缘122对第一定位凸缘112的限定可靠，参见图13，第一定位凸缘112的数量可以为多个，第一凹槽1222a的数量与第一定位凸缘112的数量相等，且第一凹槽1222a与第一定位凸缘112一一对应设置。多个第一定位凸缘112优选为在第一镜筒110的像侧端的外壁面均分布。具体地，第一定位凸缘112的数量可以为两个、三个、四个、五个等。优选地，第一定位凸缘112的数量为四个，四个第一定位凸缘112可以在第一镜筒110的像侧端的外壁面均分布。
为使第二定位凸缘122对第一定位凸缘112的限定可靠，参见图14，沿平行于第二镜筒120的光轴的方向，第二定位凸缘122的厚度尺寸h1可以为0.2mm至5.2mm。具体地，沿平行于第二镜筒120的光轴的方向，第二定位凸缘122的厚度尺寸h1可以为1mm、2mm、3mm、4mm等。
第二定位凸缘122具有背离第二镜筒120的物侧端的内壁面的第一表面1222，第一定 位凸缘112具有背离第一镜筒110的像侧端的外壁面的第二表面1121，为使第一镜筒110与第二镜筒120通过第一定位凸缘112与第二定位凸缘122实现预定位连接后，第一镜筒110相对于第二镜筒120可以调整，第二表面1121与第二镜筒120的内壁面之间、第一表面1222与第一镜筒110的外壁面之间可以存在间隙。为使间隙的设置既能够保证第一镜筒110与第二镜筒120具有足够大的可调整区间，又能够实现镜头组件10的小型化，参见图14，沿垂直于第一镜筒110的光轴的方向，第二表面1121与第二镜筒120的内壁面的间距h2可以为0.005mm至0.1mm；沿垂直于第二镜筒120的光轴的方向，第一表面1222与第一镜筒110的外壁面的间距h3可以为0.005mm至0.1mm。具体地，沿垂直于第一镜筒110的光轴的方向，第二表面1121与第二镜筒120的内壁面的间距h2可以为0.01mm、0.03mm、0.05mm、0.08mm等。沿垂直于第二镜筒120的光轴的方向，第一表面1222与第一镜筒110的外壁面的间距h3可以为0.01mm、0.03mm、0.05mm、0.08mm等
参见图6和图7，第一容纳腔111可以包括第一容纳段1111，第一容纳段1111用于安装第一镜片组130中的至少一个第一镜片。当第一镜筒110与第二镜筒120装配后，第一容纳段1111位于第二容纳腔121内。因第一容纳段1111的内径尺寸相较于第二容纳腔121的内径尺寸小，故安装于第一容纳段1111的镜片的尺寸可以更小，生产成本会更低。为此可以减少第二镜片组140中的位于第二镜筒120的物侧端的镜片的数量，而增加第一镜片组130中第一镜片的数量，从而使第一容纳段1111能够安装更多的镜片。
第一镜片组130中的第一镜片可以全部安装于第一容纳段1111，也可以部分安装于第一容纳段1111。参见图6和图7，当第一镜片组130中的第一镜片为部分安装于第一容纳段1111时，第一容纳腔111还可以包括用于安装第一镜片组130中的剩余第一镜片的第二容纳段1112，当第一镜筒110与第二镜筒120装配后，第二容纳段1112位于第二容纳腔122外。
为使第一容纳段1111能够安装更多的镜片，第一容纳段1111沿垂直于第一镜筒110的光轴的方向的长度会比较大，第一镜筒110的位于第二镜筒120内的像侧端沿垂直于第一镜筒110的光轴的方向上的长度也会比较大，当第一镜筒110的位于第二镜筒120内的像侧端的长度较大时，第一定位凸缘112可以在第一镜筒110的位于第二镜筒120内的像侧端的整个长度上设置；也可以在第一镜筒110的位于第二镜筒120内的像侧端的部分长度上设置，可参见图6。
当第一定位凸缘112在第一镜筒110的位于第二镜筒120内的像侧端的部分长度上设 置时，第一镜筒110的像侧端的未设置第一定位凸缘112的部分与第二镜筒120的内壁面可以不连接，可参见图6。当然，为实现第一镜筒110相对于第二镜筒120在一定范围内的调整，参见图7，第二镜筒120的内壁面还可以设置环形凸缘123；此时，为实现第一镜筒110与第二镜筒120的安装，第一镜筒110的像侧端需从第二镜筒120的物侧穿过通孔1221，并位于第二容纳腔121内。
为便于第一镜筒110与第二镜筒120的装配，参见图16，沿平行于第一镜筒110的光轴的方向，第一镜筒110的物侧面至第二镜筒120的像侧面的间距h4可以为0mm至5mm。具体地，沿平行于第一镜筒110的光轴的方向，第一镜筒110的物侧面至第二镜筒120的像侧面的间距h4可以为1mm、2mm、3mm、4mm等。
为实现镜头组件10的小型化，沿平行于第二镜筒120的光轴的方向，镜筒组件100的厚度尺寸可以为2mm至10mm。具体地，沿平行于第二镜筒120的光轴的方向，镜筒组件100的厚度尺寸可以为3mm、5mm、7mm、9mm等。
第二方面，参见图15，本申请实施例提供了一种镜头组件10，包括上述任意的镜筒组件100、第一镜片组130以及第二镜片组140。第一镜片组130设置于镜筒组件100的第一镜筒110的第一容纳腔111。第二镜片组140设置于镜筒组件100的第二镜筒120的第二容纳腔121。
第一镜片组130包括至少一个第一镜片，所有的第一镜片均安装于第一容纳腔111内，且所有的第一镜片均可以沿第一镜筒110的光轴顺序排列。第二镜片组140包括至少一个第二镜片，所有的第二镜片均安装于第二容纳腔121内，且所有的第二镜片均可以沿第二镜筒120的光轴顺序排列。
第一镜片组130的最大外径尺寸可以为1mm至6mm。具体地，第一镜片组130的最大外径尺寸可以为2mm、3mm、4mm、5mm等。为使第一镜片组130在第一镜筒110内的平稳固定，第一镜筒110的最大外径尺寸可以为2.5mm至10mm，且第一镜筒110的最大外径尺寸大于第一镜片组130的最大外径尺寸。具体地，第一镜筒110的最大外径尺寸可以为3mm、5mm、7mm、9mm等。此处第一镜筒110的最大外径尺寸是指第一镜筒110的像侧端的外壁面未设置第一定位凸缘112时的最大外径尺寸。
参见图16，第二镜片组140的物侧面为第三表面141。第三表面141可以位于所有的第二镜片中，最靠近第一镜片组130的一个第二镜片上。具体地，第三表面141可以为该第二镜片的物侧面。为能够降低甚至避免杂光通过第一镜筒110与第二镜筒120的连接处 进入到第二镜筒120内，能够提升摄像头组件的成像质量，镜头组件10还可以包括遮光片10c。遮光片10c可以贴设于第三表面141，遮光片10c的物侧面为第四表面11c，第一镜筒110的像侧端的外壁面以及第二镜筒120的物侧端的内壁面在第四表面11c的正投影均可以位于第四表面11c内。
为使包括第一镜片组130以及第一镜筒110的第一镜头10a与包括第二镜片组140以及第二镜筒120的第二镜头10b在安装时可以预定位，从而降低调整时的工作难度，第一镜片组130的像侧面为第五表面131，第五表面131可以设置有第一连接结构，第二镜片组140的物侧面为第三表面141，第三表面141可以设置有第二连接结构，第一连接结构与第二连接结构连接、且可相对于第二连接结构绕第二镜筒120的光轴转动。为进一步提升镜头组件10的解析力，第一连接结构除了可以相对于第二连接结构绕第二镜筒的光轴转动外，第一连接结构还可以相对于第二连接结构进行倾斜和平移的调整，从而实现镜头组件10的偏心、倾斜或间隙的校准。
为实现第一连接结构和第二连接结构连接、且可相对于第二连接结构绕第二镜筒120的光轴转动，第一连接结构可以设置于第二连接结构内，第二连接结构也可以设置于第一连接结构内。以下以第一连接结构设置于第二连接结构内为例进行详细的说明：
第一连接结构可以为第五表面131的中部设置的圆形凸起，第二连接结构可以为第三表面141的中部设置的圆形凹槽。为使圆形凸起与圆形凹槽连接后，第一镜筒110相对于第二镜筒120能够顺利的转动，圆形凸起的外周面可以为圆柱状的面，圆形凹槽的内周面可以为与圆形凸起的外周面相匹配的圆柱状的面。为使圆形凸起设置于圆形凹槽内后，在第一镜筒110相对于第二镜筒120转动的过程中，即圆形凸起相对于圆形凹槽转动的过程中，第一镜筒110的光轴与第二镜筒120的光轴的间距不会出现较大的变动，圆形凸起的中轴线可以与第一镜筒110的光轴共线，圆形凹槽的中轴线可以与第二镜筒120的光轴共线。
为使经第一连接结构和第二连接结构连接后，第一镜头10a与第二镜头10b的预定位更加可靠，参见图15至图18，第一连接结构可以为第五表面131上设置的环形凸起1311，环形凸起1311朝远离第一镜片组130的物侧面的方向延伸。第二连接结构可以为第三表面141上设置的环形槽1411，环形槽1411朝靠近第二镜片组140的像侧面的方向凹陷。环形凸起1311沿垂直于第一镜筒110的光轴的方向的所有截面均呈圆环形。环形槽1411沿垂直于第二镜筒120的光轴的方向的所有截面均呈圆环形。为使环形凸起1311设置于环形槽 1411内后，在第一镜筒110相对于第二镜筒120转动的过程中，即环形凸起1311相对于环形槽1411转动的过程中，第一镜筒110的光轴与第二镜筒120的光轴的间距不会出现较大的变动，环形凸起1311的中轴线可以与第一镜筒110的光轴共线，环形槽1411的中轴线可以与第二镜筒120的光轴共线。
参见图17，环形凸起1311具有背离第五表面131的第一圆环面1311a、绕第一圆环面1311a的内圈设置的第二内周面1311b及绕第一圆环面1311a的外圈设置的第一外周面。参见图18，环形槽1411具有面向第五表面131的第二圆环面1411a、绕第二圆环面1411a的内圈设置的第三内周面1411b及绕第二圆环面1411a的外圈设置的第二外周面。
为使环形凸起1311与环形槽1411连接后，第一镜筒110相对于第二镜筒120能够顺利的转动，环形凸起1311的第二内周面1311b可以为圆柱状的面，参见图16，环形凸起1311的第二内周面1311b也可以为从第五表面131至第三表面141的方向上，半径逐渐增大的圆台状的面。当环形凸起1311的第二内周面1311b为圆台状的面时，环形槽1411的第三内周面1411b可以为从第五表面131至第三表面141的方向上，半径逐渐增大的圆台状的面，第二内周面1311b位于第三内周面1411b的外周，为便于环形凸起1311与环形槽1411的拆装，第二内周面1311b的母线与第一镜筒110的光轴的夹角θ可以与第三内周面1411b的母线与第二镜筒120的光轴的夹角相等。
参见图16，第二内周面1311b的母线与第一镜筒110的光轴的夹角θ可以为15°至25°。通过将第二内周面1311b的母线与第一镜筒110的光轴的夹角θ限定为15°至25°，既能够避免夹角过大，即第二内周面1311b过于倾斜，造成环形凸起1311从环形槽1411内脱离，又能够保证环形凸起1311与环形槽1411连接的可靠性。具体地，第二内周面1311b的母线与第一镜筒110的光轴的夹角θ可以为18°、20°、22°等。
第三内周面1411b可以全部位于第二内周面1311b内，可参见图16。第三内表面1411b也可以部分位于第二内周面1311b内。将第三内周面1411b的位于第二内周面1311b内的部分定义为连接段，为进一步的保证环形凸起1311与环形槽1411连接的可靠性，连接段沿第三内周面1411b的母线方向的长度尺寸h5可以为0.03mm至0.15mm。具体地，连接段沿第三内周面1411b的母线方向的长度尺寸h5可以为0.07mm、0.1mm等。
环形槽1411可以为第三表面141直接向内凹陷形成。当然，为降低第二镜片组140的成型难度，参见图18，第三表面141的边缘区域可以凹陷形成台阶，台阶具有面向第五表面131的台阶面(可参见附图标记1411a)以及连接台阶面与第三表面141的第一内周面 (可参见附图标记1411b)，台阶面、第一内周面以及第二镜筒120的内壁面围合形成环形槽1411。这样仅通过在第二镜片组140的第三表面141形成台阶，就能够在第二镜片组140上形成环形槽1411，使得第二镜片组140的加工工艺更加简单，能够降低成产成本。第三表面141的边缘区域可以为从第三表面141的外边界线向内延伸预定距离的部分。预定距离可以为0.6mm至1.2mm；具体地，预定距离可以为0.8mm、1.0mm等。
为使第一镜头10a与第二镜头10b的预定位可靠，第一定位凸缘112的像侧面可以与台阶面1412抵接，环形凸起1311也可以与环形槽1411抵接。当然，为便于第一镜筒110相对于第二镜筒120的调整，可以仅将环形凸起1311与环形槽1411设置为抵接，而将第一定位凸缘112的像侧面与台阶面之间设置成具有间隙。具体地，参见图16，环形凸起1311的背离第五表面131的表面可以抵接于台阶面，且沿平行于第二镜筒120的光轴的方向，第一定位凸缘112的像侧面与台阶面1412的间距h6可以为0.005mm至0.3mm。通过上述对第一定位凸缘112的像侧面与台阶面的间距的具体限定，既能够实现第一定位凸缘112与台阶面1412存在间距，从而不会阻碍第一镜筒110与第二镜筒120的调整，又能够实现镜头组件10的小型化。具体地，沿平行于第二镜筒120的光轴的方向，第一定位凸缘112的像侧面与台阶面1412的间距h6可以为0.1mm、0.2mm等。
