具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
在本申请的描述中，术语“中心”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如可以是固定连接，也可以是可拆卸连接，还可以是抵触连接或一体的连接；对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
图1为现有技术中提供的一种电子设备。如图1所示，该结构包括盖板1、结构件2和摄像头模组3。盖板1和结构件2耦合在一起，然后结构件2与摄像头模组3中的自动对焦驱动器301 外壳的上表面进行压合，构成一个封闭空间，使摄像头模组3中的镜头302处在这个封闭空间，保证镜头302不被污染。由于现有的自动对焦驱动器301和结构件2都是硬质材料做成，所以就算压合后，很难做到自动对焦驱动器301与结构件2之间不留空隙。
如果有空隙，镜头302又不处在封闭空间中，这样仍会造成镜头302的污染。现有解决方案中，通过在自动对焦驱动器301外壳的上表面与结构件2之间的空隙中放置一块可压缩的泡棉4，使得结构件2和摄像头模组3之间形成密闭区域，防止灰尘或杂光进入摄像头成像系统，影响拍照效果，同时缓冲自动对焦驱动器301在对焦过程中摄像头模组3受到的撞击力。
但是，泡棉密封的方案中存在许多缺点，例如为了使泡棉4能够有效防尘、遮光等，则需要自动对焦驱动器301和结构件2之间的空隙有较大的密封宽度，这就造成构成的密封结构的宽度增大，这对于日益紧张的移动终端内部空间来说，是不容许的。同时，为了方便泡棉4安放在自动对焦驱动器301外壳的上表面上，通常在设计泡棉4内孔半径时，会预留一定的干涉量，这样增大了泡棉4的半径，进而造成摄像头模组3和结构件2的尺寸相应的增大。
另外，如果泡棉4在贴附、装配出现偏差时，泡棉4会露出在结构件2内部，这样从盖板1看摄像头的镜头302时，可能看到泡棉4，这严重影响摄像头的外观问题。
图2为本申请实施例提供的一种电子设备。如图2所示，该电子设备，其包括盖板1、结构件2、摄像头模组3(图中未示出)和密封件5。其中，摄像头模组3包括自动对焦驱动器301和镜头302。
盖板1用于保护摄像头模组3中的镜头302。对于移动终端的前置摄像头来说，盖板1可以为移动终端显示屏；对于移动终端的后置摄像头来说，盖板1可以为移动终端后面保护摄像头模组3的玻璃。
结构件2是指在摄像头周边能够与摄像头模组3压合、使摄像头模组3和盖板1之间形成一个密封空间的结构。其中间位置一般有个圆柱形孔，用于保护摄像头模组3中的镜头302和方便镜头302在这个圆柱形孔中进行伸缩。结构件2可以为移动终端的整机中框、镜片装饰件，其材料可以为金属、塑胶件或其它各种嵌件。结构件2的与自动对焦驱动器301外壳进行压合的表面可以有凸包、凸筋等结构，或凹坑、凹槽等结构。
结构件2可以直接粘贴在盖板1，也可以在盖板1上添加其它装置，再与结构件2进行粘贴。在一个实施例中，对于移动终端的前置摄像头来说，可以将显示屏延伸到盖板1上的与结构件2粘贴的位置，然后再将结构件2粘贴在显示屏对应的位置上，这样相比较将机构件2直接粘贴在盖板1上，可以提高移动终端的屏占比。
自动对焦驱动器301用于调整镜头302进行自动对焦，使拍照更加清晰。自动对焦驱动器301的外壳形状可以是方形、圆形或其它形状，外壳的与结构件2进行压合的表面上还可以有凸包、凸筋等结构，或凹坑、凹槽等结构。其外壳材料可以为金属、塑胶、复合材料、多种材料嵌件等。
制作在自动对焦驱动器301外壳或结构件2上的密封件5，可以使得结构件2和摄像头模组3之间形成密封结构。密封件5的材料理论上可以为任何可压缩材料，但是考虑到摄像头模组3的精确度，最优选的材料为软胶。下文在实施例中说明时，密封件5均为软胶组成。
密封件5在自动对焦驱动器301外壳或结构件2上制作的方法可以为双射注塑法、LIMP成型法、二次成型法等等，所采用的方法根据自动对焦驱动器301外壳或结构件2的材料来确定。
在一个实施例中，密封件5制作在自动对焦驱动器301外壳上这种情况，制作自动对焦驱动器301外壳时，在自动对焦驱动器301外壳上直接制作密封件5，使密封件5贴附在自动对焦驱动器301外壳上，然后与结构件2进行压合，使得盖板1、结构件2和摄像头模组3形成一个密 封空间的结构。
其中，密封件5的结构和形状不限，密封件5的与结构件2进行压合的表面可以做成平面或做成凸筋、凹槽等各种形状，然后嵌入到结构件2上对应的凹槽或凸筋中，来加强防尘效果；密封件5的与自动对焦驱动器301外壳接触的表面可以做成平面或做成凸包、凹坑等各种形状，通过嵌入到自动对焦驱动器301外壳的对应的凹坑或凸包中，来增强自动对焦驱动器301和密封件5的结合力。
密封件5不仅可以制作在自动对焦驱动器301外壳的上表面上，也可以制作在自动对焦驱动器301外壳的侧边、凸筋凸包等结构上。只要能与结构件2或盖板1进行密封，构成密封空间，密封件5可以制作在自动对焦驱动器301外壳的任意位置。
在另一个实施例中，密封件5制作在结构件2上这种情况，在结构件2的与自动对焦驱动器301外壳进行压合的表面上直接制作密封件5，然后与自动对焦驱动器301进行压合，使得盖板1、结构件2和摄像头模组3形成一个密封空间的结构。
其中，密封件5的结构和形状不限，密封件5的与自动对焦驱动器301外壳进行压合的表面可以做成平面或做成凸筋、凹槽等各种形状，然后嵌入到自动对焦驱动器301外壳上对应的凹槽或凸筋中，来加强防尘效果；密封件5的与结构件2相接触的表面可以做成平面或做成凸包、凹坑等各种形状，通过嵌入到结构件2对应的凹坑或凸包中，来增强结构件2和密封件5的结合力。
本申请通过将密封件5制作在自动对焦驱动器301外壳或结构件2上，使得密封件5与自动对焦驱动器301外壳或结构件2成为一体，然后结构件2直接与自动对焦驱动器301外壳的上表面无缝压合，这样就不需要为了有效防尘、遮光而增大自动对焦驱动器的密封结构的宽度。同时，由于密封件5在自动对焦驱动器301外壳或结构件2上制作，就不需要因为预留一定的干涉量导致摄像头模组3和结构件2的尺寸增大问题，也不需要考虑密封件5在贴附、装配出现偏差带来的外观问题。
实施例一
图3为本申请实施例一提供的一种自动对焦驱动器外壳的剖面结构图。如图3所示，自动对焦驱动器301外壳由塑胶、复合材料等材料注塑成型。在其上表面设置有几个凹槽，用于和密封件5耦合。根据自动对焦驱动器301外壳的材质，则采用双射注塑法在自动对焦驱动器301外壳的上表面上制作密封件5，使密封件5和自动对焦驱动器301外壳成为一体。
制作完成后如图4所示，密封件5的与自动对焦驱动器301外壳接触的表面上可以做成凸包等任意形状，使其嵌入到自动对焦驱动器301外壳的内部，来增强自动对焦驱动器301和密封件5的结合力；密封件5的与结构件2进行压合的表面可以做成平面或做成凸筋、凹槽等各种形状，然后嵌入到结构件2上对应的凹槽或凸筋中，来加强防尘效果。然后将制作成的外壳组装成自动对焦驱动器301，再进行后段的摄像头模组3的组装，构成如图5所示的摄像头模组3。
最后将组装完成的摄像头模组3与结构件2进行压合，使得盖板1、结构件2和摄像头模组3形成一个密封空间的结构，得到如图6所示的电子设备。
本申请实施例一在自动对焦驱动器301外壳由塑胶、复合材料等材料制成时，采用双射注塑法在自动对焦驱动器301外壳的上表面上注塑形成密封件5，然后密封件5与结构件压合，形成密封空间。此方案避免了密封件5的装配偏差，减小驱动器的平面尺寸，解决外观能够看到密封件偏心问题。同时有效解决现有密封方案无法解决的自动对焦模组小型化的问题。
实施例二
图7为本申请实施例二提供的一种自动对焦驱动器外壳的剖面结构图。如图7所示，自动对焦驱动器301外壳由塑胶、复合材料等材料注塑成型。在其上表面或/和侧边设置几个凹槽，用于与密封件5耦合。根据自动对焦驱动器301外壳的材质，则采用双射注塑法在自动对焦驱动器301外壳的上表面和侧边上制作密封件5，使密封件5和自动对焦驱动器301外壳成为一体。相比较实施例一的方案，本实施例将密封件2延伸到自动对焦驱动器301外壳的侧边上，增强了密封件5和自动对焦驱动器301外壳之间的结合力。
制作完成后，密封件5的与自动对焦驱动器301外壳接触的表面上可以做成凸包等任意形状，使其嵌入到自动对焦驱动器301外壳的内部，来增强自动对焦驱动器301和密封件5的结合力；密封件5的与结构件2进行压合的表面可以做成平面或做成凸筋、凹槽等各种形状，然后嵌入到结构件2上对应的凹槽或凸筋中，来加强防尘效果；在自动对焦驱动器301外壳侧边的密封件5的外表面可以直接做成平面，方便摄像头模组3与移动终端中其它器件相结合。然后将制作成的外壳组装成自动对焦驱动器301，再进行后段的摄像头模组3的组装，构成如图8所示的摄像头模组3。其中左边无密封件5，这样使得在摄像头模组3组装时，摄像头模组3侧边面的密封件5会受整机结构挤压，使摄像头模组3定位面与移动终端整机结构定位面相结合，提升摄像头模组3的组装精度，解决摄像头模组3的组装偏心问题。
最后将组装完成的摄像头模组3与结构件2进行压合，使得盖板1、结构件2和摄像头模组3形成一个密封空间的结构，得到如图9所示的电子设备。
另外，密封件5不仅仅可以制作在自动对焦驱动器301外壳的侧边的3个面，还可以制作在自动对焦驱动器301外壳的侧边的4个面、或2个面、或1个面，也可以根据需求制作每个侧边面的全部或部分。例如如图图10所示的4个面有密封件5的摄像头模组3。
本申请实施例二在自动对焦驱动器301外壳由塑胶、复合材料等材料制成时，采用双射注塑法在自动对焦驱动器301外壳的上表面和侧边上注塑形成密封件5，然后自动对焦驱动器301外壳上表面上的密封件5与结构件压合，形成密封空间。此方案避免了密封件5的装配偏差，减小驱动器的平面尺寸，解决外观能够看到密封件偏心问题。同时有效解决现有密封方案无法解决的自动对焦模组小型化的问题。另外，相比较实施例一，实施例二在自动对焦驱动器301外壳的侧边上也制作有密封件5，来增强了密封件5和自动对焦驱动器301外壳之间的结合力。
实施例三
图11为本申请实施例三提供的一种摄像头模组的剖面结构图。如图11所示，自动对焦驱动器301外壳由金属成型。根据自动对焦驱动器301外壳的材质，则采用LIMP成型法在自动对焦驱动器301外壳上制作密封件5，使密封件5和自动对焦驱动器301外壳成为一体。
制作完成后如图12所示，密封件5与自动对焦驱动器301外壳的上表面接触的表面上可以做成平面，由于金属和软胶之间结合力本来就好，就不需要做成凸包等任意形状来增强自动对焦驱动器301和密封件5的结合力；密封件5的与结构件2进行压合的表面可以做成平面或做成凸筋、凹槽等各种形状，然后嵌入到结构件2上对应的凹槽或凸筋中，来加强防尘效果。然后将制作成的外壳组装成自动对焦驱动器301，再进行后段的摄像头模组3的组装，构成如图13所示的摄像头模组3。
最后将组装完成的摄像头模组3与结构件2进行压合，使得盖板1、结构件2和摄像头模组3形成一个密封空间的结构，得到如图14所示的电子设备。
本申请实施例三在自动对焦驱动器301外壳由金属材料制成时，采用LIMP成型法在自动对焦驱动器301外壳的上表面上形成密封件5，然后密封件5与结构件压合，形成密封空间。此方案避免了密封件5的装配偏差，减小驱动器的平面尺寸，解决外观能够看到密封件偏心问题。同时有效解决现有密封方案无法解决的自动对焦模组小型化的问题。
实施例四
图15为本申请实施例四提供的一种自动对焦驱动器外壳的剖面结构图。如图15所示，自动对焦驱动器301外壳由金属成型，其中在外壳上表面上有一圈凸起的圆柱形的棱边，该棱边用于保护镜头302。根据自动对焦驱动器301外壳的材质，则采用LIMP成型法在自动对焦驱动器301外壳上表面的棱边上制作密封件5，使密封件5和自动对焦驱动器301外壳成为一体。
制作完成后如图16所示，密封件5的形状可以为圆环帽形状，可以覆盖在圆柱形的棱边上端口以及接近上端口附近的侧边上，使棱边的上端口紧密的嵌入在密封件5中，增加了自动对焦驱动器301和密封件5的结合力；密封件5的与结构件2进行压合的表面可以做成平面或做成凸筋、凹槽等各种形状，然后嵌入到结构件2上对应的凹槽或凸筋中，来加强防尘效果。然后将制作成的外壳组装成自动对焦驱动器301，再进行后段的摄像头模组的组装，构成如图17所示的摄像头模组3。
最后将组装完成的摄像头模组3与结构件2进行压合，使得盖板1、结构件2和摄像头模组3形成一个密封空间的结构，得到如图18所示的电子设备。
可选地，如果凸起的棱边高度比较高，且镜头可以在凸起的圆柱形的棱边里面自由伸缩，则移动终端整机中就不需要结构件2，此时密封件5可以直接与盖板1进行压合，这样减少移动终端的结构部件，降低成本。
本申请实施例三在自动对焦驱动器301外壳由金属材料制成时，采用LIMP成型法在自动对焦驱动器301外壳的上表面上形成密封件5，然后密封件5与结构件压合，形成密封空间。此方案避免了密封件5的装配偏差，减小驱动器的平面尺寸，解决外观能够看到密封件偏心问题。同时有效解决现有密封方案无法解决的自动对焦模组小型化的问题。另外，实施例二中将密封件5制作在凸起的圆柱形的棱边上，这样可以减少移动终端的结构部件，降低成本。
实施例五
图19为本申请实施例五提供的密封件制作在结构件上的剖面结构图。如图19所示，在结构件2的与自动对焦驱动器301外壳进行压合的表面上制作密封件5，密封件5直接在结构件2中成型，使得密封件5和结构件2成为一体。然后将摄像头组件3组装到移动终端整机上，使密封件5与自动对焦驱动器301外壳压合，使得盖板1、结构件2和摄像头模组3形成一个密封空间的结构，得到如图20所示的电子设备。
其中，盖板1和结构件2之间直接粘接，也可以不直接粘接。在一个例子中，如图21所示，对于移动终端的后置摄像头，将盖板1嵌入到结构件2中，这样减小了摄像头自动对焦驱动器的密封结构的厚度。在另一个例子中，如图22所示，对于移动终端的前置摄像头，将显示屏延伸到盖板1上的与结构件2粘贴的位置，然后再将结构件2粘贴在显示屏对应的位置上，这样相比较将机构件2直接粘贴在盖板1上，可以提高移动终端的屏占比。。
本申请通过将密封件5在与自动对焦驱动器301外壳进行压合的表面上制作结构件2，使得密封件5和结构件2成为一体，结构件2直接与自动对焦驱动器301外壳的上表面无缝压合，这样就不需要为了有效防尘、遮光而增大摄像头自动对焦驱动器的密封结构的厚度。同时，由 于密封件5在结构件2上制作，就不需要因为预留一定的干涉量导致摄像头模组3和结构件2的尺寸增大问题，也不需要考虑密封件5在贴附、装配出现偏差带来的外观问题。同时避免了密封件5的装配偏差，减小驱动器的平面尺寸，解决外观能够看到密封件偏心问题。同时有效解决现有密封方案无法解决的自动对焦模组小型化的问题。
在本说明书的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以适合的方式结合。
