 本发明的实施方式
下面结合附图和实施方式对本申请作进一步说明。
如图1所示，本申请一实施例提供一种应用于电子设备中的镜头模组10，该镜头模组10包括镜筒100及镜片。镜筒100包括具有通光孔111的顶壁110及顶壁110弯折延伸的筒壁120，顶壁110与筒壁120围合形成腔体，镜片收容于腔体内。
如图1所示，镜片的数量为四个，包括沿物侧至像侧的方向依次收容在腔体内的第一镜片201、第二镜片202、第三镜片203及第四镜片204。可以理解地，在其他实施例中，镜片的数量也可以根据实际需要作出改变。
一并参考图2及图3，第四镜片204包括用于成像的光学部210及环绕光学部210设置的连接部220。连接部220包括相对设置的物侧面221及像侧面222，以及连接物侧面221及像侧面222的侧表面223。筒壁120包括相对设置的内表面121及外表面122，且内表面121包括与侧表面223抵接的抵接面1211，抵接面1211向远离侧表面223的方向凹陷形成有第一容胶槽123，侧表面223向远离抵接面1211的方向凹陷形成有第二容胶槽224。
同时参考图4，第一容胶槽123与第二容胶槽224连通以形成容胶槽101。筒壁120还设有注胶孔124，且注胶孔124与第一容胶槽123连通，以使得胶水能够由注胶孔124注入至第一容胶槽123与第二容胶槽224形成的容胶槽101内。在其他实施例中，注胶孔124还可以直接与第二容胶槽224连通，并通过第二容胶槽224与第一容胶槽123连通。
可以理解地，在其他实施例中，容胶槽101也可以仅由抵接面1211或侧表面223凹陷形成，即，胶水仅填充在第一容胶槽123或第二容胶槽224内。
值得一提的是，在本实施例中，注胶孔124自外表面122向靠近抵接面1211的方向凹陷形成，便于组装人员注入胶水。当然，在其他实施例中，注胶孔124也可以开设在内表面121位于第四镜片204的像侧的部分。而且，在本实施例中，注胶孔124包括依次连通的第一注胶孔1241、第二注胶孔1242及第三注胶孔1243，第一注胶孔1241与第一容胶槽123连通，第三注胶孔1243由外表面122向靠近抵接面1211的方向凹陷形成。第二注胶孔1242的轴线为直线，且第二注胶孔1242的轴线与镜头模组10的光轴300平行。即，第一注胶孔1241的轴线及第三注胶孔1243的轴线均与第二注胶孔1242的轴线呈夹角设置，注胶孔124的轴线为非直线型，以使得第二注胶孔1242的内壁与内表面121的距离，以及第二注胶孔1242的内壁与外表面122的距离在与镜头模组10的光轴300平行的方向上处处相等，以保证镜筒100的强度，还可以延长注胶孔124的轴线的长度，以增加注胶孔124的容积。在其他实施例中，注胶孔124的轴线也可以为直线型，并与镜头模组10的光轴300呈夹角设置。
在本实施例中，第一容胶槽123及第二容胶槽224均为环形槽。组装时，通过向注胶孔124内注入胶水，胶水能够填充至第一容胶槽123及第二容胶槽224内，以将第四镜片204与镜筒100连接。一并参考图5，当第一容胶槽123及第二容胶槽224内填充满胶水后，多余的胶水能够容纳在注胶孔124内，以防止胶水溢流至第四镜片204的光学部210而影响镜头模组10成像。而且，通过设置第一容胶槽123及第二容胶槽224，能够增加胶水与镜筒100及第四镜片204的接触面积，以增强镜头模组10的稳定性，从而提高镜头模组10及使用该镜头模组10的电子设备的成像质量。
在其他实施例中，第一容胶槽123或第二容胶槽224中的一个也可以是环绕光轴300间隔设置的多个凹槽。当第一容胶槽123为环绕光轴300间隔设置的多个凹槽时，注胶孔124也可以设有多个，且注胶孔124的数量与形成第一容胶槽123的凹槽的数量相同，每一注胶孔124对应于每一凹槽。
组装时，可以同时向多个注胶孔124内注入胶水，以提高组装效率，并保证每一形成第一容胶槽123的凹槽内均填充有胶水。当然，注胶孔124的数量也可以只有一个。此时，胶水由注胶孔124注入，并由与注胶孔124对应的凹槽流入至第二容胶槽224内。当第二容胶槽224填充满胶水后，胶水能够填充至其余的凹槽内，且多余的胶水能够容纳在注胶孔124内。
可以理解地，在其他实施例中，也可以是第二容胶槽224为环形槽，第一容胶槽123为环绕光轴300设置的多个凹槽。或者，第一容胶槽123及第二容胶槽224均为绕光轴300间隔设置的多个凹槽。此时，形成第一容胶槽123的凹槽的数量与形成第二容胶槽224的凹槽的数量相同，每一形成第一容胶槽123的凹槽对应于每一形成第二容胶槽224的凹槽。而且，注胶孔124也需设有多个，且注胶孔124的数量与形成第一容胶槽123的凹槽的数量相同，每一注胶孔124对应于每一形成第一容胶槽123的凹槽。组装时，多个注胶孔124内均需要注入胶水，胶水由注胶孔124流入至形成第一容胶槽123的凹槽及形成第二容胶槽224的凹槽内，以将第四镜片204与镜筒100通过胶水连接。
进一步地，在本实施例中，主要参考图4，第一容胶槽123包括沿物侧至像侧的方向顺次连接的第一连接面1231、第一底面1232及第二连接面1233，第一连接面1231及第二连接面1233均与抵接面1211连接。在物侧至像侧的方向上，第一连接面1231向远离光轴300的方向倾斜，第二连接面1233向靠近光轴300的方向倾斜。
第二容胶槽224包括沿物侧至像侧的方向顺次连接的第三连接面2241、第二底面2242及第四连接面2243，且第三连接面2241及第四连接面2243均与侧表面223连接。在物侧至像侧的方向上，第三连接面2241向靠近光轴300的方向倾斜，第四连接面2243向远离光轴300的方向倾斜。即，第一容胶槽123的入口处的尺寸最大，第二容胶槽224的出口处的尺寸最大，以使得注胶孔124内的胶水能够快速填充至第一容胶槽123及第二容胶槽224内。而且，第一连接面1231及第二连接面1233倾斜设置既可以保证胶水与第一容胶槽123的接触面积，又可以保证镜筒100的强度，防止镜筒100为增加第一容胶槽123与胶水的接触面积而使得镜筒100在第一容胶槽123的位置处的强度减弱。同样地，第三连接面2241及第四连接面2243倾斜设置也既可以保证胶水与第二容胶槽224的接触面积，又可以保证第四镜片204的强度。
可以理解地，在其他实施例中，也可以取消第一底面1232及第二底面2242。此时，第一连接面1231直接与第二连接面1233连接，第三连接面2241直接与第四连接面2243连接，第一容胶槽123及第二容胶槽224均为三角形凹槽。
值得一提的是，主要参考图4，第一连接面1231与第一底面1232的连接处、第二连接面1233与第一底面1232的连接处、第三连接面2241与第二底面2242的连接处、第四连接面2243与第二底面2242的连接处、以及注胶孔124与第二容胶槽224的连接处均为弧形结构，避免应力集中而影响镜筒100及第四镜片204的强度。
以上所述的仅是本申请的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本申请创造构思的前提下，还可以做出改进，但这些均属于本申请的保护范围。
