[0061] 具体地, 至少一个平板 322上设有多个翼板 324。 本实施例中, 各翼板 324相互 间隔设置, 且每个平板 322上均设有翼板 324。 翼板 324在嵌件注塑工艺过程中嵌 入塑胶台 31内, 通过设置翼板 324可加强金属架 32与塑胶台 31的结合强度。 本实 施例中, 两个相对平板 322上的翼板 324尺寸大于另外两个相对平板 322上的翼板 324的尺寸。 在一种实施方式中, 滤光片 40安装在平板 322上, 并覆盖第二通孔 1 02。

[0071] 支撑座 30包括塑胶台 31和金属架 32, 金属架 32固定在塑胶台 31, 滤光片 40夹设 在塑胶台 31和金属架 32之间。 塑胶台 31、 金属架 32与滤光片 40三者可以通过嵌 件注塑 (insert
molding) 工艺结合在一起, 即在制作形成塑胶台 31时, 将金属架 32与滤光片 40 放入一模具中, 然后向模具的空腔内注入熔融的塑胶, 使熔融的塑胶包覆在金 属架 32与滤光片 40的外围并在冷却之后形成塑胶台 31, 从而金属架 32与滤光片 4 0嵌入在塑胶台 31中。 但是, 将金属架 32与滤光片 40固定至塑胶台 31的方式并不 以此为限, 例如还可以通过胶粘、 卡扣、 螺锁或过盈配合的方式, 实现将金属 架 32固定至塑胶台 31上, 同时将滤光片 40夹设在塑胶台 31和金属架 32之间即可
[0072] 具体地, 当塑胶台 31、 金属架 32与滤光片 40三者通过嵌件注塑工艺结合在一起 时, 如图 18和图 19所示, 先提供金属架 32和滤光片 40; 如图 20所示, 再将滤光 片 40贴合到金属架 32的一侧, 例如将滤光片 40贴合到金属架 32的上侧; 如图 21 所示, 然后通过嵌件注塑工艺注塑成型塑胶台 31, 使塑胶台 31与金属架 32、 滤 光片 40结合在一起, 且滤光片 40夹设在金属架 32和塑胶台 31之间。 由于是通过 嵌件注塑工艺将滤光片 40夹设固定在金属架 32和塑胶台 31之间, 滤光片 40嵌入 到塑胶台 31内, 只需较小的宽度架在塑胶台 31上即可, 有利于进一步缩小摄像
头模组水平方向上的尺寸。
[0073] 塑胶台 31的中部设有第一通孔 101以供光线通过, 第一通孔 101贯穿塑胶台 31。
滤光片 40位于塑胶台 31的第一通孔 101内, 感光芯片 20对应第一通孔 101而设。
[0074] 本实施例中, 塑胶台 31的内侧壁设有用于承载滤光片 40的固定板 312, 滤光片 4 0的外周缘夹设在固定板 312与金属架 32之间。 具体在本实施例中, 塑胶台 31位 于滤光片 40的上方, 金属架 32位于滤光片 40的下方。 可以理解, 也可将塑胶台 3 1设于滤光片 40的下方, 将金属架 32置于滤光片 40上方。
[0075] 本实施例中, 可通过粘结等方式将镜头组件 50直接固定于塑胶台 31的上表面, 因此无需在塑胶台 31上设置与镜头组件 50的外螺纹结合的内螺纹。 本实施例中 , 摄像头模组为定焦摄像头。
[0076] 如图 18所示, 金属架 32包括第一平板 322a、 第二平板 322b、 第三平板 322c和第 四平板 322d。 第一平板 322a与第二平板 322b相对设置, 第三平板 322c和第三平板 322d相对设置且连接在第一平板 322a与第二平板 322b之间, 第一平板 322a、 第二 平板 322b、 第三平板 322c、 第四平板 322d围绕形成与第一通孔 101对应的第二通 孑 L102。 各个平板 322a、 322b、 322c、 322d的一部分露出于塑胶台 31的外部, 各 个平板 322a、 322b、 322c、 322d的另一部分通过嵌件注塑工艺嵌入塑胶台 31内, 从而使金属架 32与塑胶台 31结合在一起。 可以理解, 也可将各个平板 322a、 322b 、 322c、 322d的全部均嵌入塑胶台 31内, 这样可使塑胶台 31与金属架 32的结合强 度更高。 在一种实施例中, 金属架 32采用铝材或铁材通过裁切或冲压的方式形 成, 金属架 32的具体材料可根据实际需要自由选择。
[0077] 具体地, 至少一个平板 322上设有多个翼板 324和连接板 326。 本实施例中, 连 接板 326通过至少两个翼板 324连接于第三平板 322c和第四平板 322d上, 且连接板 326与第三平板 322c及第四平板 322d之间均留有间隙, 各翼板 324相互间隔设置。 翼板 324在嵌件注塑工艺过程中嵌入塑胶台 31内, 通过设置翼板 324可加强金属 架 32与塑胶台 31的结合强度。 由于连接板 326与第三平板 322c之间以及连接板 326 与第四平板 322d之间留有间隙, 注塑成型时, 塑胶台 31可填充于间隙内, 从而 进一步加强金属架 32与塑胶台 31的结合强度。 在一种实施方式中, 滤光片 40安 装在第一平板 322a、 第二平板 322b、 第三平板 322c和第四平板 322d上, 并覆盖第
二通孔 102。
[0078] 塑胶台 31的下方设有多个支撑板 33 , 各支撑板 33与塑胶台 31连接且位于塑胶台 31的四周边缘位置, 各支撑板 33用于将塑胶台 31固定至电路板 10上。 具体地, 支撑板 33可以为四个, 四个支撑板 33围绕形成矩形。 本实施例中, 如图 17和图 2 1所示, 多个支撑板 33中至少一个支撑板 33为金属板, 其余支撑板 33为塑胶板, 金属板从金属架 32—体延伸形成, 塑胶板从塑胶台 31—体延伸形成, 且金属板 的厚度小于塑胶板的厚度。
[0079] 在本实施例中, 多个支撑板 33包括第一支撑板 33a、 第二支撑板 33b、 第三支撑 板 33c和第四支撑板 33d, 第一支撑板 33a与第二支撑板 33b相对设置, 第三支撑板 33c与第四支撑板 33d相对设置, 第三支撑板 33c和第四支撑板 33d连接于第一支撑 板 33a与第二支撑板 33b之间, 第一支撑板 33a、 第二支撑板 33b、 第三支撑板 33c 和第四支撑板 33d首尾相连形成矩形框体结构。
[0080] 在本实施例中, 第一支撑板 33a为金属板, 第一支撑板 33a从金属架 32的第一平 板 322a—体延伸形成, 具体地, 第一支撑板 33a可从第一平板 322a的一侧边缘弯 折 90。一体形成。 第二支撑板 33b、 第三支撑板 33c和第四支撑板 33d为塑胶板, 第 二支撑板 33b、 第三支撑板 33c和第四支撑板 33d从塑胶台 31—体延伸形成, 即第 二支撑板 33b、 第三支撑板 33c、 第四支撑板 33d和塑胶台 31通过注塑一体形成。
[0081] 本实施例中, 金属的第一支撑板 33a的两端分别形成朝向外侧的延伸板 327, 延 伸板 327的末端形成垂直于延伸板 327而设的钩部 328, 延伸板 327和钩部 328均嵌 入塑胶台 31内, 以进一步增强金属架 32与塑胶台 31的结合强度。
[0082] 本实施例中, 第一支撑板 33a由金属制成, 强度较高, 可将第一支撑板 33a的厚 度 hi设计成小于第二支撑板 33b、 第三支撑板 33c、 第四支撑板 33d的厚度 h2, 例 如第一支撑板 33a的厚度 hi为 0.09mm〜 0.15mm, 第二支撑板 33b、 第三支撑板 33 c、 第四支撑板 33d的厚度 h2为 0.3mm, 但并不以此为限。 由于支撑座 30的第一支 撑板 33a厚度 hi较小, 当第一支撑板 33a设置在手机的顶部边框位置时, 可将摄像 头模组 100安装在手机屏幕更靠近顶部边框的位置, 减小了摄像头模组 100占据 手机屏幕的尺寸, 满足手机屏占比要求, 提高了手机使用体验。
[0083] 可以理解, 在其他实施例中, 还可以将第一支撑板 33a、 第二支撑板 33b设置为
分别从金属架 32的第一平板 322a、 第二平板 322b—体延伸形成的金属板, 而第三 支撑板 33c和第四支撑板 33d为从塑胶台 31—体延伸形成的塑胶板; 或者将第一支 撑板 33a、 第二支撑板 33b、 第三支撑板 33c设置为分别从金属架 32的第一平板 322 a、 第二平板 322b、 第三平板 322c—体延伸形成的金属板, 而第四支撑板 33d为从 塑胶台 31—体延伸形成的塑胶板; 或者第一支撑板 33a、 第二支撑板 33b、 第三支 撑板 33c和第四支撑板 33d设置为分别从金属架 32的第一平板 322a、 第二平板 322b 、 第三平板 322c和第四平板 322d—体延伸形成的金属板。 通过将更多的支撑板 33 设置为金属板, 可进一步减小摄像头模组 100的尺寸。
[0084] 本实施例的摄像头模组 100中, 支撑座 30通过塑胶台 31与金属架 32结合形成, 并将滤光片 40结合在塑胶台 31与金属架 32之间, 一方面嵌入塑胶台 31的金属架 3 2可大大加强支撑座 30的强度, 形成较好的支撑作用; 另一方面, 将滤光片 40夹 设固定在塑胶台 31与金属架 32之间, 无需通过粘接等方式另行固定滤光片 40, 避免滤光片 40在固定过程中被弄脏。 再者, 本实施中由于是通过嵌件注塑工艺 将滤光片 40夹设在金属架 32和塑胶台 31之间, 滤光片 40嵌入到塑胶台 31内, 只 需较小的宽度架在塑胶台 31上即可, 有利于缩小摄像头模组水平方向上的尺寸
[0085] 进一步地, 通过将至少一个支撑板 33设置成厚度较小但强度较高的金属板, 从 而进一步减小摄像头模组的尺寸。 当将摄像头模组 100安装于移动终端时, 摄像 头模组 100的安装位置可以更靠近移动终端 200顶部的边框, 能减小摄像头模组 1 00占据移动终端 200屏幕的尺寸, 提高移动终端 200屏占比, 进而提高了移动终 端 200的使用体验。
