 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，本申请实施例一提供一种应用于电子设备中的镜头模组100，该镜头模组100包括镜筒10，镜片20、遮光片30及遮光板40。镜筒10包括具有通光孔111的顶壁11及自顶壁11的边缘弯折延伸的筒壁12，顶壁11与筒壁12连接并围合形成腔体，镜片20、遮光片30及遮光板40均位于腔体内，镜片20设有多片，遮光片30及遮光板40位于相邻的镜片20之间，镜片20包括用于成像的光学部以及环绕所述光学部的周边部，遮光片30及遮光板40具***于镜片20的周边部之间，能够遮挡周边部的杂光，避免杂光影响镜头模组100的成像质量。
在本实施例中，镜片20设有五片，遮光片30及遮光板40位于从物侧至像侧计算的第三片和第四片镜片20之间，为便于后续说明，将遮光片30及遮光板40两侧的镜片20称作第一镜片21和第二镜片22。可以理解地，在其他实施例中，镜片20的数量，以及遮光片30与遮光板40具***于哪两片镜片20之间均可以根据实际需要确定。
一并参考图2及图3，遮光片30包括遮光部31及支撑部32，支撑部32抵接于镜片20，并沿光轴方向延伸，支撑部32能够阻挡经遮光板40反射的杂光，以进一步提升镜头模组100的成像质量。而且，支撑部32沿光轴方向的高度小于遮光板40沿光轴方向的高度。具体地，第一镜片21的周边部包括朝向第二镜片22的第一支撑面211，第二镜片22的周边部包括朝向第一镜片21的第二支撑面221，支撑部32位于第一支撑面211与第二支撑面221之间，且第一支撑面211及第二支撑面221的间距大于支撑部32沿光轴方向的厚度，能够避免遮光片30安装在两片镜片20之间时由于受力产生形变，以保证遮光片30的遮光效果。
进一步地，在本实施例中，遮光片30能够沿平行光轴的方向移动，以根据电子设备的使用状态自动调整遮光片30与第一镜片21及第二镜片22的在光轴方向上的相对位置。当然，在其他实施例中，遮光片30也可以与第一镜片21或第二镜片22粘接。
值得一提的是，遮光片30还能够沿垂直光轴的方向移动，使得遮光片30能够根据电子设备的使用状态自动调整遮光片30与遮光板40在垂直光轴方向上的相对位置。此时，在垂直于光轴的截面上，支撑部32远离光轴一侧的尺寸小于遮光片30靠近光轴一侧的尺寸。即，当遮光片30的轴线与光轴共线时，支撑部32与遮光板40间隔设置。
在本实施例中，支撑部32与遮光部31的夹角为直角，能够节省遮光部31的材料。具体地，以图3为例说明，在遮光部31需要遮挡第一镜片21及第二镜片22的面积确定的情况下，即遮光部31沿光轴方向在第一镜片21及第二镜片22上的投影面积确定的情况下，遮光部31沿垂直于光轴方向延伸能够节省遮光部31的材料。在其他实施例中，支撑部32与遮光部31的夹角也可以为锐角。
在本实施例中，遮光片30还包括过渡部34，过渡部34自支撑部32的一端朝向光轴弯折延伸并连接支撑部32及遮光部31。主要参考图3，支撑部32包括朝向遮光部31的第一表面321，过渡部34包括第二表面341，遮光部31包括第三表面312，第一表面321、第二表面341及第三表面312位于遮光片30的同一侧，且第一表面321与第二表面341的夹角α小于第二表面341与第三表面312的夹角β。通过设置过渡部34，遮光部31通过过渡部34与支撑部32间接连接，使得遮光部31相对支撑部32的位置能够根据实际需要灵活设置。一并参考图4，图4中的遮光部31相对图3中的遮光部31靠近第二镜片22，制造者可以根据实际需要限定遮光部31相对支撑部32的具***置。而且，一并参考图5及图6，并分别对应图3及图4，第一表面321与第二表面341的夹角α等于第二表面341与第三表面312的夹角β，此时，α角与β角均为直角，即遮光部31与支撑部32及过渡部34均垂直。当然，在其他实施例中，夹角α及夹角β的值也可以根据实际需要改变，例如，夹角α为锐角，夹角β为钝角。
值得一提的是，遮光片30一般通过一体成型的方式生产，为便于生产，遮光片30各处的厚度一般需要保持一致。通过设置过渡部34，相对于遮光部31直接与支撑部32连接的方式，可以避免遮光部31与支撑部32的连接处的材料变厚而影响遮光片30的生产质量。当然，如图7所示，若遮光部31自支撑部32的端部弯折形成，此时虽然没有设置过渡部34，仍可以保证遮光片30的厚度处处相等。
如图3至图7所示，在上述实施例中，遮光片30还包括自支撑部32远离过渡部34的一端沿垂直光轴方向朝向遮光板40延伸的折弯部36。折弯部36环绕支撑部32设置，并用于与镜片20抵接，且折弯部36用于与镜片20抵接的表面与支撑部32用于与镜片20抵接的表面共面，折弯部36能够增加遮光片30与第一镜片21或第二镜片22的接触面积。而且，在上述实施例中，遮光部31及过渡部34均自支撑部32的端部延伸，遮光部31或过渡部34也与第一镜片21接触，遮光片30在支撑部32与遮光部31或过渡部34连接的一侧与第一镜片21接触的面积较大，因此只在支撑部32远离遮光部31的一端设置折弯部36，且可以使遮光片30的厚度保持一致。在其他实施例中，还可以在支撑部32的两端均设置折弯部36。
应当注意的是，折弯部36并不是必须的，如图8至图12所示的实施例六至实施例十中，与图3至图7所示的实施例一至实施例五一一对应，其区别仅在于取消了折弯部36。此时，遮光片30仅通过支撑部32与第一镜片21及第二镜片22抵接。而且，为了使得遮光片30能够在垂直光轴的方向上移动，在垂直于光轴的截面上，折弯部36远离光轴一侧的尺寸小于遮光板40靠近光轴一侧的尺寸。即，当遮光片30的轴线与光轴共线时，折弯部36与遮光板40间隔设置。
此外，如图13所示，在实施例十一中，遮光片30设有多个环绕光轴间隔设置缺口301，缺口301的数量为4-20个，具体数量可以根据实际需要确定。在本实施例中，缺口301具体设置于支撑部32及折弯部36上，用于卡设于镜片20或遮光板40上，以限制遮光片30绕其轴线旋转。可以理解地，在图8至图12所示的实施例中，由于遮光片30未设置折弯部36，此时，缺口301仅设置在支撑部32上。
综上，上述遮光片30，其遮光片30及遮光板40能够遮挡周边部的杂光，避免杂光影响镜头模组100的成像质量。同时，由于支撑部32抵接于周边部，并沿平行光轴方向延伸，支撑部32能够阻挡经遮光板40反射的杂光，以进一步提升镜头模组100的成像质量。而且，支撑部32沿光轴方向的高度小于遮光板40沿光轴方向的高度，能够避免遮光片30安装在两片镜片20之间时由于受力产生形变，以保证遮光片30的遮光效果。
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。
