 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。
请一并结合图1至图13，先对本申请提供的镜头模组10进行说明。该镜头模组10包括具有收容空间110的镜筒100和收容于收容空间110内的至少一个镜片200。该镜筒100包括内侧壁120和底壁130，该内侧壁120能够围设成收容空间110，该底壁130上形成有光圈孔131，用于供成像光线通过。进一步地，镜片200具有相对内侧壁120设置的外侧壁210，镜头模组10还包括设置在内侧壁120和外侧壁210两者中的一者上的多个凸起220，以及形成于内侧壁120和外侧壁210两者中的另一者上的多个凹槽140，各凸起220一一对应沿镜头模组10轴向插设于各凹槽140。本实施例中，凸起220设置在外侧壁210上，凹槽140形成在内侧壁120上。可以理解为在其他实施例中，凸起220设置在内侧壁120上。凹槽140形成在外侧壁210上，或者，各凸起220中部分凸起220位于内侧壁120上，另一部分凸起220位于外侧壁210上，与之相对应的，部分凹槽140形成在内侧壁120上，另一部分凹槽140形成在外侧壁210上。具体地，本实施例中，凸起220的个数为8个且各凸起220以轴向为轴均匀分布于外侧壁210上。同样地，凹槽140的个数为8个且与各凸起220一一对应分布于内侧壁120上。可以理解为在其他实施例中，凸起220的个数还可以为三个以上的其他数值且各凸起220也可以不均匀分布在内侧壁120上，只要保证各凸起220不分布在同一半圆内即可。
进一步地，凸起220具有沿镜头模组10径向延伸的第一尺寸，与该凸起220相对应的凹槽140具有沿径向延伸的第二尺寸，第一尺寸大于第二尺寸，即在径向上凸起220外凸于外侧壁210的尺寸大于在径向上凹槽140内凹于内侧壁120的尺寸。进一步地，凸起220具有第一连接部，凹槽140的槽壁具有与第一连接部抵接的第二连接部。将镜片200与镜筒100装配时，凸起220沿轴向插设于凹槽140。由于在径向上凸起220只有部分收容于凹槽140，使得内侧壁120与外侧壁210之间在非第一连接部和第二连接部抵接处形成间隙，因此，镜片200与镜筒100只形成八个连接位置，避免镜片200外侧壁210与镜筒100内侧壁120整圈配合，将整圈配合改为八个抵接配合，在保证装配稳定性的同时避免在外侧壁210和/或内侧壁120圆度存在问题时的装配异常，提高了良率。进一步地，第一连接部与第二连接部为点接触、线接触或面接触，以实现抵接，有效降低了镜片200和镜筒100在非连接位置处的加工精度，降低了镜头模组10的成本。具体地，轴向平行于图3中箭头X1所指方向以及图9中箭头X2所指方向，径向平行于图5中箭头Y1所指方向以及图11中箭头Y2所指方向。
请一并结合图2至图7，在一个实施例中，凸起220的各截面面积沿插设方向均相等，截面位于垂直于轴向的平面内。该凸起220包括第一弯曲面221和位于第一弯曲面221两侧的第二弯曲面222。第一弯曲面221向远离外侧壁210方向外凸。本实施例中，第一弯曲面221沿径向向远离外侧壁210方向外凸。进一步地，第二弯曲面222包括位于外侧壁210上的第一侧边2221和向远离外侧壁210方向延伸至第一弯曲面221的第二侧边2222，第二弯曲面222向远离外侧壁210方向内凹。截面包括前文平面截取第一弯曲面221形成的第一圆弧和平面截取第二弯曲面222形成的第二圆弧，第一圆弧的角度为98°~132°，第二圆弧的角度为48°~63°，第一圆弧的弦长是第二圆弧的弦长的1~2倍。
本实施例中，槽壁包括第三弯曲面141和位于第三弯曲面141两侧的第四弯曲面142。本实施例中，第三弯曲面141沿径向向远离内侧壁120方向内凹，第四弯曲面142向远离内侧壁120方向内外凸。第一弯曲面221正对且抵设于第三弯曲面141，以在第一弯曲面221上形成第一连接部，在第三弯曲面141上形成第二连接部。前文平面截取第三弯曲面141形成第一弧线，截取第四弯曲面142形成第二弧线。第一弧线的曲率小于第一圆弧的曲率，第一弧线的弦长为第一圆弧的弦长的2倍。第二弧线的曲率小于第二圆弧的曲率，第二弧线的弦长和第二圆弧的弦长相等。
进一步地，第二弯曲面222的内凹方向与径向的夹角为30°~60°。第四弯曲面142的外凸方向与径向的夹角小于第二弯曲面222的内凹方向与径向的夹角。凸起220具有沿轴向延伸的第三尺寸，凹槽140具有沿轴向延伸的第四尺寸，第三尺寸小于第四尺寸。
请一并结合图8至图13，在另一个实施例中，凸起220的各截面面积沿插设方向逐渐减小，截面位于垂直于轴向的平面内。凸起220的轴线与轴向的夹角为3°~8°。该凸起220包括第一弯曲面221和位于第一弯曲面221两侧的第二弯曲面222。第一弯曲面221向远离外侧壁210方向外凸。本实施例中，第一弯曲面221沿径向向远离外侧壁210方向外凸。进一步地，第二弯曲面222包括位于外侧壁210上的第一侧边2221和向远离外侧壁210方向延伸至第一弯曲面221的第二侧边2222，第二弯曲面222向远离外侧壁210方向内凹。截面包括前文平面截取第一弯曲面221形成的第一圆弧和平面截取第二弯曲面222形成的第二圆弧，第一圆弧的角度为98°~132°，第二圆弧的角度为48°~63°，第一圆弧的弦长是第二圆弧的弦长的1~2倍。
本实施例中，槽壁包括第三弯曲面141和位于第三弯曲面141两侧的第四弯曲面142。本实施例中，第三弯曲面141沿径向向远离内侧壁120方向内凹，第四弯曲面142向远离内侧壁120方向内外凸。第一弯曲面221正对且抵设于第三弯曲面141，以在第一弯曲面221上形成第一连接部，在第三弯曲面141上形成第二连接部。前文平面截取第三弯曲面141形成第一弧线，截取第四弯曲面142形成第二弧线。第一弧线的曲率小于第一圆弧的曲率，第一弧线的弦长为第一圆弧的弦长的2倍。第二弧线的曲率小于第二圆弧的曲率，第二弧线的弦长和第二圆弧的弦长相等。
进一步地，第二弯曲面222的内凹方向与径向的夹角为30°~60°。第四弯曲面142的外凸方向与径向的夹角小于第二弯曲面222的内凹方向与径向的夹角。凸起220具有沿轴向延伸的第三尺寸，凹槽140具有沿轴向延伸的第四尺寸，第三尺寸小于第四尺寸。
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。
