具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
如图1所示，现有技术中镜头模组100包括镜筒110、镜片组120、压环130及粘接胶140。镜片组120安装于镜筒110的内部腔室，镜片组120与镜筒110的内壁面抵接。镜片组120包括位于镜筒110像侧端的镜片，该镜片具有像侧端面121，压环130设置于镜片的像侧端面121的外周边缘处，且压环130与像侧端面121和镜筒110的内壁面均抵接。其中，粘接胶140粘接于压环130与镜筒110的内壁面的连接处，以使得镜片固定于镜筒110内。
但是，使用粘接胶140对压环130与镜筒110的内壁面的连接处进行点胶时，由于粘接胶140的用量难以控制及粘接胶140的流动性，易出现胶水杂光的风险和镜头模组100可靠性不佳的问题，从而导致镜片的解析力变差，且影响镜头模组100的产品良率和用户的使用体验。
针对上述技术问题，如图2-3所示，本实施例提供了一种镜头模组100。该镜头模组100包括镜筒110、镜片组120以及紧固件130。镜筒110具有内部腔室111，镜片组120固定于镜筒110的内部腔室111，且镜片组120的外 周面与镜筒110的内壁面抵接。镜片组120包括位于镜筒110像侧端的镜片，该镜片具有像侧面121。且镜片组120还可以包括与该镜片相对的另外一个镜片，其中，镜片组120的与具有像侧面121相对的镜片包括物侧面122。需要理解的是，本实施例中，镜片的朝向待拍摄物的一侧表面为物侧面122，镜片的背离待拍摄物的一侧表面为像侧面121，像侧端为镜筒110朝向待拍摄物的一侧。而镜片组120可以只包括一个镜片也可以包括多个镜片，当镜片组120只包括一个镜片时，像侧面121以及物侧面122位于镜片相对的两端。当镜片组120由多个组成时，像侧面121可以位于镜片组120的最靠近像侧端的镜片上，而物侧面122可以表示位于镜片组120的距离像侧端最远的镜片上。
像侧面121包括光学区1211以及绕光学区1211的非光学区1212，光学区1211用于透射待拍摄物反射的光线，以使得该光线照射在镜头模组100内部的感光元件上，以用于成像。非光学区1212不用于透射待拍摄物反射的光线，其用于镜片与镜筒110的安装固定。其中，紧固件130配置成与镜筒110卡合时抵压镜片的非光学区1212，以使得镜片紧固于镜筒110的内部腔室111。
对比现有技术中的镜头模组，本实施例的镜头模组100中采用紧固件130与镜筒110卡合连接，且紧固件130与镜筒110的卡合连接可以给予镜片抵压力而使得镜片固定于镜筒110的内部腔室111。镜筒110与紧固件130卡合连接的结构可以为现有的所有已知的卡合结构，镜筒110与紧固件130卡合连接可以理解为紧固件130与镜筒110仅通过纯机械结构的配合而连接，两者的连接不需要借助其它连接材料，且两者的连接为可拆卸式的。与现有技术中的镜头模组100相比，本实施例中的镜头模组100减少了点胶作业的工序，从而避免出现胶水杂光的风险和压环点胶范围小而导致镜片与镜筒110连接不牢固的问题。所以，本实施例的技术方案保证了镜片解析力和固定的可靠性，提升了镜头模组100的产品良率和用户的使用体验。同时，紧固件130还可拆卸的 与镜筒110连接，提升了镜头模组100的拆装方便性。
为了使紧固件130可有效的对镜片进行抵压，本申请施例中，镜筒110包括位于像侧端的端面开口112，像侧端为镜筒110对待拍摄物进行拍摄时，镜筒110的背离待拍摄物的一端。镜片的具有非光学区1212的端部伸出端面开口112，紧固件130与镜片的非光学区1212的边缘处抵接，以用于提供镜片紧固于镜筒110的内部腔室111的抵压力。
上述实施例中，镜片的具有非光学区1212的端部凸出镜筒110的端面开口112，避免了镜筒110的具有端面开口112的端部与紧固件130的位置干涉，且还保证了紧固件130与镜片之间的连接可靠性、镜片与镜筒110的连接可靠性。
紧固件130与镜筒110连接的可靠性直接影响到镜头模组100的产品品质，本实施例中，如图4所示，紧固件130可以包括第一固定部131以及与第一固定部131连接的第二固定部132。第一固定部131具有面向镜片的像侧面121的接触面1311，且第一固定部131的接触面1311与镜片的非光学区1212抵接。
镜筒110限定出光路轴线113，光路轴线113为光呈竖向(以图4所示的方位为参照)穿过镜片中心而形成的轴线。镜筒110包括绕光路轴线113布置的外周面114，外周面114设置有第一卡合部1141。第二固定部132设有第二卡合部1321，且第二固定部132可以具有面向镜筒110的第一连接面1322、与第一连接面1322相对的第二连接面1323以及远离第一固定部131的接触面1311的第三连接面1324。其中，第一连接面1322的其中一边和第二连接面1323的其中一边均与第一固定部131的接触面1311连接，第三连接面1324与第二连接面1323邻接。第二卡合部1321位于第一连接面1322和第三连接面1324之间。
安装紧固件130时，紧固件130预置于镜筒110的像侧端正上方，按压紧固件130以使得紧固件130的第二卡合部1321沿镜筒110的外周面114自像侧面121朝向物侧面122的方向滑动，以将第二卡合部1321卡合于第一卡合部1141。其中，与镜筒110卡合连接的紧固件130会产生变形，以使得卡合于第一卡合部1141的第二卡合部1321会受到第一卡合部1141的朝向第一方向X的作用力，以将紧固件130与镜筒110固定连接。且紧固件130的第一固定部131也会对镜片产生沿第一方向X的抵压力，以使得镜片紧固于镜筒110的内部腔室111。其中，第一方向X为镜片的像侧端指向镜片的物侧端的方向，并平行于光路轴线113。
本实施例中，通过第一卡合部1141与第二卡合部1321卡合，可以使紧固件130与镜筒110的连接更为牢固，从而提高镜头模组100的可靠性。
上述实施例中，第一卡合部1141和第二卡合部1321可以为任意的相配合的结构，以用于固定连接紧固件130和镜筒110。本实施例中，第一卡合部1141可以为第一凸起，第二卡合部1321可以为第二凸起。第一凸起自镜筒110的外周面114朝远离内部腔室111的方向延伸，第一凸起包括背离内部腔室111的第一端面11411，且第一端面11411与光路轴线113倾斜设置，即第一端面11411的延长面与光路轴线113相交。第二凸起自第二固定部132的第一连接面1322朝靠近镜筒110的方向延伸，第二凸起包括面向第一固定部131的第二端面13211，且第二端面13211与光路轴线113倾斜设置。其中，当第一卡合部1141与第二卡合部1321卡合时，第一端面11411与第二端面13211抵接，且第一凸起给予第二凸起沿第一方向X的抵压预应力，第一方向X为像侧面121指向物侧面122的方向。
需要注意的是，本实施例列举第一端面11411以及第二端面13211均与光路轴线113倾斜设置仅仅用于示意性说明。但不限于此，第一端面11411以及 第二端面13211还可以与光路轴线113存在其他的相对位置关系，例如第一端面11411以及第二端面13211还可以与光路轴线113垂直。
其中，当第一卡合部1141与第二卡合部1321卡合时，第一凸起的第一端面11411与第二凸起的第二端面13211抵接，且第一凸起给予第二凸起沿第一方向X的作用力。需要注意的是，作用力可以是第一端面11411与第二端面13211均垂直于光路轴线113横向布置时相互挤压而产生的朝向第一方向X(如图4所示的方向)的合力，也可以是第一端面11411与第二端面13211均与光路轴线113呈一夹角布置时相互挤压而产生的朝向第一方向X的分力。且第一端面11411以及第二端面13211均呈斜面时，可方便第一凸起与第二凸起的安装，提升镜头模组100的使用方便性。
均为凸起结构的第一卡合部1141和第二卡合部1321可以提供足够的作用力，以使得镜片可牢固的紧固于镜筒110的内部腔室内。本实施例中，所列举第一卡合部1141和第二卡合部1321均为凸起结构仅仅用于示意性说明，本实施例不对第一卡合部1141和第二卡合部1321的具体结构做限定，所有具有与本实施例的第一卡合部1141和第二卡合部1321相似或相同的结构，以使得镜片牢固的固定于镜筒110的结构，均在本申请的保护范围内。
紧固件130与镜筒110的卡合连接为镜片提供抵压力。但是，紧固件130与镜片抵接的稳定性直接关系到镜片与镜筒110的连接可靠性。如图5所示，本实施例中，镜片的非光学区1212可以包括位于其边缘的抵接面12121，抵接面12121呈圆环状，且垂直于光路轴线113。紧固件130与镜筒110卡合连接时，第一固定部131的接触面1311抵接于抵接面12121，给予镜片周向边缘朝向第一方向X的抵压力，以使得镜片紧固于镜筒110的内部腔室111。
为了方便紧固件130的安装，如图6所示，本施例中，镜筒110包括面向接触面1311的顶面115，第一凸起可以具有面向第一固定部131的引导斜面 11412。引导斜面11412与光路轴线113倾斜布置，且引导斜面11412的一端连接于外周面114，其另一端连接于第一凸起的远离外周面114的端部。第一凸起还包括第三端面11413，第三端面11413平行于光路轴线113，第三端面11413为第一凸起的端部面。其中，沿第一方向X上引导斜面11412、第三端面11413及第一端面11411依次顺序排列分布，引导斜面11412与镜筒110的顶面115邻接。第二凸起可以具有面向镜筒110的第四端面13212以及面向镜筒110的第五端面13213。第四端面13212平行于光路轴线113，第五端面13213与光路轴线倾斜布置。其中，沿第一方向X上第二端面13211、第四端面13212及第五端面13213依次顺序排列分布，第二端面13211与第一连接面1322邻接，第五端面13213与第三连接面1324邻接。
将第一卡合部1141与第二卡合部1321卡合过程中，第二凸起的第五端面13213与第一凸起的引导斜面11412抵接，按压紧固件130以使得第二凸起的第五端面13213沿引导斜面11412朝向第一方向X滑动，第二凸起最终穿过第一凸起的第三端面11413，且第一凸起的第一端面11411与第二凸起的第二端面13211抵接。其中，第二固定部132的第一连接面1322与第一凸起的第三端面11413抵接，而第二凸起的第四端面13212与镜筒110的外周面114抵接。
由上述实施例可知，在第一凸起设置有引导斜面11412可以可简单方便的实现紧固件130与镜筒110的安装，从而提高镜头模组100的生产效率且方便紧固件130与镜筒110之间的拆卸。
需要注意的是，在第一凸起上设置有引导斜面11412仅仅是本实施例列举的较佳实施例，所有具有与本实施例中的引导斜面11412相似或相同，以方便紧固件130与镜筒110之间固定连接的结构均在本申请的保护范围内。
如图7所示，本实施例中，还可以对紧固件130的尺寸进行了限定，以使 得本实施例中的紧固件130与镜筒110的连接更为牢固。本实施例中，第二固定部132的第一连接面1322与第一卡合部1141的引导斜面11412之间的夹角为a，a的度数范围可以在5°～60°之间，例如，a的度数可以是5°、10°或60°。顶面115远离内部腔室111的一边到第一连接面1322的最短距离为b，b的尺寸范围可以是0.05mm～0.5mm，例如，b的尺寸可以是0.05mm、0.2mm或0.5mm。第一固定部131的接触面1311平行于顶面115，接触面1111与顶面115间垂直距离为c，c的尺寸范围可以为0mm～0.05mm,例如，c的尺寸可以是0mm、0.02mm、或0.05mm。第一卡合部1141的第一端面11411的其中一边与第三端面11413的一边相交形成一交界线，交界线上一点到第一固定部131的接触面1311的垂直距离为d，d的尺寸范围可以为0.1mm～0.8mm，例如，d的尺寸可以是0.1mm、0.2mm或0.8mm。第一固定部131的接触面1311平行于第二固定部132的第三连接面1324，接触面1311到第三端面11413的垂直距离为e，e的尺寸范围可以为0.2mm～1mm，例如，e的尺寸可以是0.2mm、0.6mm或1mm。第二卡合部1321的第五端面13213与镜筒110的外周面114之间的夹角为f，f的度数范围可以在5°～60°之间，例如，f的度数可以是5°、10°或60°。镜筒110的外周面114与第一卡合部1141的第一端面11411之间的夹角为g，g的度数范围可以在100°～160°之间，例如，g的度数可以是100°、120°或160°。外周面114与第一连接面1322之间的垂直距离为h，h的尺寸范围可以为0.05mm～0.5mm，例如，h的尺寸可以为0.05mm、0.2mm或0.5mm。外周面114与第二连接面1323之间的垂直距离为j，j的尺寸范围可以为0.25mm～1mm，例如，j的尺寸可以为0.25mm、0.7mm或1mm。
上述实施例中，通过限定a、f及g的夹角范围和b、c、d、e、h及j的尺寸大小，可以间接限定出紧固件130的尺寸大小。经过上述数据限定出的紧固件130对镜片和镜筒110具有优异的固定连接的效果，可有效解决镜头模组 100中出现的胶水杂光和镜头可靠性不佳的问题，从而提升镜片的解析力和用户的使用体验。
需要注意的是，上述a、b、c、d、e、f、g、h及j各参数，均是本实施例列举的较佳实验参数，但本实施例并不对该参数范围做具体限定，列举上述数据仅仅用于示意性说明，所有具有与本实施例中的紧固件130相同或相似以使得镜片可牢固的固定于镜筒110内的结构，均在本申请的保护范围内。
为了，保证第一卡合部1141和第二卡合部1321之间的连接强度，如图8所示，本实施例中，第一凸起可以为圆环形，第一凸起绕光路轴线113布置于镜筒110的外周面114。
呈周向布置于镜筒110的外周面114的第一凸起，可提供足够多的与第二卡合部1321卡合的位置，从而提升第一凸起与第二凸起的连接强度。
同样，第一固定部131可以为环形，且第一固定部131绕光路轴线113布置，第一固定部131的内环边缘与非光学区1212的抵接面12121抵接，第一固定部131的外环边缘与第二固定部132连接。
呈环形的第一固定部131的内环边缘与非光学区1212的抵接面12121抵接，可以为镜片的周向边缘提供沿第一方向X的抵压力，以使得镜片的周向受力更加均匀，不仅能够使镜片与镜筒110的连接更加牢固，还可保证镜片的水平度。其中，为了镜头模组100的美观，紧固件130的外环可以为矩形。
需要注意的是，第一凸起和第一固定部131均可以为任意形状，本申请列举呈圆环形第一凸起及呈环形第一固定部131，皆仅仅用于示意性说明，所有具有与本实施例中的第一凸起和第一固定部131相同或相似，以使得镜片可牢固的固定于镜筒110内的结构，均在本申请的保护范围内。
通常，紧固件130与镜筒110连接的可靠性会直接影响镜头模组100的产品品质。如图9所示，本实施例中，第二固定部132的数量可以为多个，例如， 第二固定部132的数量可以为2个或4个。各第二固定部132均分别连接于第一固定部131的接触面1311的内环边缘处，且各第二固定部132均绕光路轴线113圆形阵列布置。各第二固定部132一一对应的第二卡合部1321均与第一卡合部1141卡接，以将紧固件130和镜筒110固定连接。
上述实施例中，通过在第一固定部131的接触面1311的内环边缘处设置多个数量的第二固定部132，可以使紧固件130与镜筒110的连接更加牢固，从而增强镜头模组100的可靠性，提升镜头模组100的产品良率。
紧固件130与镜筒110的连接会给予镜片抵接力，从而使镜片的位置发生偏移。为了保证镜片的水平度，本实施例中，各第二固定部132间可相隔预定的距离呈圆形阵列分布于接触面1311的内边缘处，以使得各第二固定部132的各第二卡合部1321呈等间距布置于镜筒110的外周面114，且第二卡合部1321均与第一卡合部1411卡接，以使得镜片与镜筒110固定连接。
等间距周向布置于第一固定部131的内环边缘处的各第二固定部132，可以增强紧固件130与镜筒110之间的连接强度，并保证镜片的水平度，从而提升镜头模组100的品质。
然而，各第二固定部132可以等间距布置于第一固定部131的内环边缘处，也可不等间距布置于第一固定部131的内环边缘处。本实施例并不对第二固定部132的具有布置形式做具体限定。而呈等间距布置于第一固定部131接触面1311的内环边缘处的各第二固定部132，可以使得紧固件130与镜筒110间的连接处受力更加均匀，从而保证镜片的水平度。
本实施例还提供了一种电子设备10，包括上述的镜头模组100。本实施例提供的电子设备可以是任何具有摄像功能的电子产品，包括但不限于以下类别：电视机、笔记本电脑、桌上型显示器、平板电脑、数码相机、手机、智能眼镜、车载显示器、医疗设备、工控设备等，本实施例对此不作具体限定。
