背景技术
数码相机、摄像装置、手机等移动终端内的镜头组件中，镜筒和组装于其内的镜片之间存在一定的干涉量，但是镜片和镜筒之间的干涉量过大会导致镜片变形，从而影响镜头组件的解析力下降问题，影响拍照品质。如何设计使得镜片和镜筒之间结合的干涉量在期望的范围内，不会影响镜片产生异常变形，保证镜头组件解析力，保证成像品质，为业界在研究的方向。
发明内容
本申请实施例提供了一种镜头组件、摄像头组件及终端，解决了因镜筒和镜片组装干涉量大而导致的镜片变形及影响成像品质的问题。
第一方面，本申请提供了一种镜头组件，包括镜筒和镜片，所述镜筒中空且包括内表面，具体而言，镜筒呈两端开口的筒状，内表面包围形成的收容空间用于安装镜片。镜筒的中心轴为镜头组件的光轴。所述镜片安装在所述镜筒内，所述镜片包括与所述内表面干涉配合的侧面，具体而言，镜片的中心区域为透光区，镜片的边缘区域包围中心区域，边缘区域用于将镜片组装至镜筒，侧面为边缘区域的外侧与镜筒配合的表面，侧面与镜筒的内表面之间接触且干涉配合。镜筒的内表面设有挖空区，挖空区可以为任意形状的凹槽，例如方形凹槽、弧形凹槽、半圆形凹槽、三角形凹槽等，也可以为不规则的形状，挖空区为通过去除材料的方式，在镜筒的内壁上形成内凹区域，挖空区也可以由多条细条纹状沟道或细缝形成的区域。所述侧面包括微凸结构，镜片侧面的微凸结构是镜片在加工过程中出现的不规则的表面突出结构，例如，镜片的侧面理论上应当设计为圆柱状的表面，但是在生产制作的过程中，由于模具结构、加工工艺等原因，导致镜片侧面不可避免形成微凸结构。本申请通过所述镜片与所述镜筒之间的相对旋转，改变微凸结构与所述挖空区之间的配合量，以调节所述镜筒与所述镜片之间的组装干涉量。镜片安装至镜筒后，侧面与内表面之间干涉配合，当干涉量较大时会导致镜片变形，影响成像品质，本申请可以通过旋转镜片使得微凸结构的至少部分移动至挖空区内，即，通过挖空区吸收微凸结构与内表面之间的部分干涉量，当微凸结构全部收容在挖空区内时，镜片与镜筒之间的干涉量最小。本申请通过镜片与镜筒间干涉量的减少，控制镜片的变形量，从而保证成像品质。
一种实施方式中，所述挖空区内填充缓冲材料，所述镜片与所述挖空区内的所述缓冲材料相接触，以吸收所述镜片与所述镜筒内表面之间的组装干涉。缓冲材料可以为胶水、泡棉、硅胶等具有弹性缓冲性能的材质。
所述挖空区的数量为多个，所述多个挖空区彼此间隔排布于在所述镜片的外围，且正对所述镜片的所述侧面。挖空区数量为两个或两个以上的设置可以提高镜片与镜头之间干涉量的效率，旋转镜片的过程中，可以使微凸结构快速遇到一个挖空区。当然，镜片侧面 的微凸结构的数量也不限定为只有一个，也可以为两个或两个以上。这样的话，两个或两个以上的微凸结构与两个或两个以上的挖空区配合，可以更大幅度调节镜片与镜筒之间的干涉量。
一种实施方式中，所述挖空区包括第一挖空区和第二挖空区，所述第一挖空区为一个或多个第一挖空结构，所述第二挖空区为一个或多个第二挖空结构；所述镜片包括顶层镜片、底层镜片及层叠在所述顶层镜片和所述底层镜片之间的至少一个中间镜片，所述至少一个中间镜片与所述镜筒之间间隙配合；所述至少一个第一挖空结构与所述顶层镜片的所述微凸结构相配合；所述至少一个第二挖空结构与所述底层镜片的所述微凸结构相配合。
本实施方式确定了多层镜片的架构，顶层镜片和底层镜片的位置确定后，中间镜片的位置就固定了，因此，中间镜片与镜筒之间间隙配合，可以确保中间镜片不受组装干涉力影响产生变形。顶层镜片可以为一层或两层镜片的架构。底层镜片也可以为一层或两层镜片架构。
一种实施方式中，所述镜筒设有导胶槽，所述导胶槽从所述镜筒的端面延伸至所述挖空区，所述导胶槽用于在所述镜片组装至所述镜筒后向所述挖空区内填充胶水。导胶槽内填充胶水，可以使得镜头组件强度更好，整体刚性更佳，确保镜片不产生位移和变形。
一种实施方式中，所述导胶槽包括第一导胶槽和第二导胶槽，所述第一导胶槽从所述镜筒顶端的端面延伸至与所述顶层镜片相配合的所述挖空区，所述第二导胶槽从所述镜筒底端的端面延伸至与所述底层镜片相配合的所述挖空区。本实施方式提供了两个导胶槽，分别针对顶层镜片和底层镜片进行点胶，以填充胶水在挖空区中。使得胶水填充的过程更容易，且不会影响中间层镜片。
一种实施方式中，所述镜筒内壁还设有连通沟道，所述多个第一挖空结构之间通过连通沟道相连接，所述第二挖空结构之间通过连通沟道相连接。
所述挖空区包括凹槽或彼此紧邻且平行设置的多条细缝。
一种实施方式中，所述多条细缝沿着所述镜筒的轴向方向上平行并列排布，且对应设置在所述顶层镜片或所述底层镜片的外围。
即，同一个位置的挖空区可以是一个完整的凹槽状结构，也可以是多条细缝结构。
第二方面，本申请还提供一种摄像头组件，包括电路板、芯片、滤光片及如前述任意一种实施方式所述的镜头组件，所述芯片设于所述电路板的顶面，所述滤光片固定在所述镜头组件之所述镜筒的底面，所述镜筒的底面连接至所述电路板的顶面，所述芯片与所述镜片相对设置。
第三方面，本申请还提供一种终端，包括所述的摄像头组件。

具体实施方式
下面结合本发明实施例中的附图对本发明实施例进行描述。
本申请提供了一种镜头组件，应用于终端产品的摄像头组件中，终端可以为手机、平板、摄像机等。
请参阅图1、图2和图3，镜头组件包括镜筒10和镜片20。所述镜筒10中空且包括内表面15，具体而言，镜筒10为两端开口的筒状，内表面15包围形成的收容空间用于安装镜片20。镜筒10包括第一端面11和第二端面13，镜筒10的中心轴为镜头组件的光轴。所述镜片20安装在所述镜筒10内，所述镜片20包括与所述内表面15干涉配合的侧面21，具体而言，镜片20的中心区域为透光区，镜片20的边缘区域包围中心区域，边缘区域用于将镜片20组装至镜筒10，侧面21为边缘区域的外侧与镜筒10配合的表面，侧面21与镜筒10的内表面15之间接触且干涉配合。本申请实施例所提及的干涉配合指的是镜片20和镜筒10的过盈配合关系，具体而言，在外力作用下，将镜片20组装内镜筒10内部时，镜片20的侧面21与镜筒10内表面15之间相互挤压，挤压力使得镜片20被固定在镜筒10内，挤压也容易使镜片20产生变形，这种安装关系称为干涉配合。
镜筒10的内表面15设有挖空区12，挖空区12可以为任意形状的凹槽，例如方形凹槽、弧形凹槽、半圆形凹槽、三角形凹槽等，也可以为不规则的形状，还可以为由多条细条纹状沟道或细缝形成的区域。挖空区12为通过去除材料的方式在镜筒10的内壁上形成内凹区域。
请参阅图4和图5，所述镜片20的侧面21包括微凸结构22，镜片20侧面21的微凸结构22是镜片20在加工过程中出现的不规则的表面突出结构，例如，镜片20的侧面21理论上应当设计为圆柱状的光滑表面，但是在生产制作的过程中，由于模具结构、加工工艺等原因，导致镜片20侧面21不可避免形成微凸结构22。微凸结构22的形状可以为任意形状，如图5所示的实施例中，镜片20包括四种不同形状的微凸结构22。
本申请在镜筒10设置挖空区12，当镜片20装入镜筒10时，可以通过旋转所述镜片20，使得所述镜片20的微凸结构22落入挖空区12，改变微凸结构22与所述镜筒的配合量，从而调节所述镜筒10与所述镜片20之间的组装干涉量，即调节镜筒10和镜片20之间的相互挤压力。
镜片20安装至镜筒10后，侧面21与内表面15之间干涉配合，会导致镜片20变形，影响成像品质。如图4所示的实施例，微凸结构22与挖空区12没有交集，且二者之间彼此间隔，此时，微凸结构22与镜筒10的内表面15之间干涉量较大，容易引起镜片20变形。如图5所示通过旋转镜片20，使得微凸结构22的至少部分移动至挖空区12内，即，通过挖空区12吸收微凸结构22与内表面15之间的部分干涉量，减少镜筒10和镜片20之间的相互挤压力。当微凸结构22全部收容在挖空区12内时，镜片20与镜筒10之间的干 涉量最小。本申请通过镜片20与镜筒10间干涉量的减少，控制镜片20的变形量，从而保证成像品质。
请参阅图1，一种实施方式中，所述挖空区12内填充缓冲材料30，所述缓冲材料30用于与所述镜片20接触且吸收所述镜片20与所述镜筒10内表面15之间的组装干涉。缓冲材料30可以为胶水、泡棉、硅胶等具有弹性缓冲性能的材料。
请参阅图2和图3，一种实施方式中，所述挖空区12的数量为多个，所述多个挖空区12彼此间隔排布于在所述镜片20的外围，且正对所述镜片20的所述侧面21。挖空区12数量为两个或两个以上的设置可以提高镜片20与镜头之间干涉量的效率，旋转镜片20的过程中，可以使微凸结构22快速遇到一个挖空区12。当然，镜片20侧面21的微凸结构22的数量也不限定为只有一个，也可以为两个或两个以上。这样的话，两个或两个以上的微凸结构22与两个或两个以上的挖空区12配合，可以更大幅度调节镜片20与镜筒10之间的干涉量。
一种实施方式中，所述挖空区12包括第一挖空区和第二挖空区，所述第一挖空区为一个或多个第一挖空结构，所述第二挖空区为一个或多个第二挖空结构。
一种实施方式中，所述镜片20包括顶层镜片、底层镜片及层叠设置在所述顶层镜片和所述底层镜片之间的中间镜片，所述至少一个第一挖空结构与所述顶层镜片的所述微凸结构相配合；所述顶层镜片与所述镜筒之间、所述底层镜片与所述镜筒之间均为干涉配合，所述至少一个第二挖空结构与所述底层镜片的所述微凸结构相配合。
如图1所示，镜片20包括依次层叠设置的第一镜片21、第二镜片22、第三镜片23、第四镜片24、第五镜片25和第六镜片26。第一镜片21、第二镜片22为顶层镜片，第三镜片23、第四镜片24、第五镜片25为中间镜片，第六镜片26为底层镜片。所述挖空区12分布在所述顶层镜片和所述底层镜片的外围，所述中间镜片与所述镜筒之间间隙配合。本实施方式确定了多层镜片的架构，顶层镜片和底层镜片的位置确定后，中间镜片的位置就固定了，因此，中间镜片与镜筒10之间间隙配合，可以确保中间镜片不受组装干涉力影响产生变形。顶层镜片可以为一层或两层镜片的架构。底层镜片也可以为一层或两层镜片架构。
一种实施方式中，所述镜筒10设有导胶槽，所述导胶槽从所述镜筒10的端面延伸至所述挖空区12，所述导胶槽用于在所述镜片20组装至所述镜筒10后向所述挖空区12内填充胶水。导胶槽内填充胶水，可以使得镜头组件强度更好，整体刚性更佳，确保镜片20不产生位移和变形。
一种实施方式中，所述导胶槽包括第一导胶槽14和第二导胶槽16，所述第一导胶槽14从所述镜筒10顶端的端面延伸至与所述顶层镜片(即第一镜片21)相配合的所述挖空区12，第一导胶槽14延伸至与第一镜片21和第二镜片22相配合的挖空区12的位置。所述第二导胶槽16从所术镜筒10底端的端面延伸至与所述底层镜片(即第六镜片26)相配合的所述挖空区12。本实施方式提供了两个导胶槽14，16，分别针对顶层镜片和底层镜片进行点胶，以填充胶水在挖空区12中。使得胶水填充的过程更容易，且不会影响中间层镜片20。
如图2所示，一种实施方式中，所述镜筒10内壁还设有连通沟道19，所述镜片20的 外围的所述挖空区12包括至少两个挖空结构，所述连通沟道19用于连通所述至少两个挖空结构12。
所述挖空区12包括凹槽或彼此紧邻且平行设置的多条细缝。一种实施方式中，所述挖空区12包括多条细缝，沿着所述镜筒10的轴向方向上，所述多条细缝平行并列排布，且对应设置在所述顶层镜片或所述底层镜片的外围，如图1所示的第一镜片21的外围对应设置的挖空区12包括三个并列设置的细缝。也就是说，同一个位置的挖空区12可以是一个完整的凹槽状结构，也可以是多条细缝结构。
请参阅图6，本申请还提供一种摄像头组件，包括电路板70、芯片80、滤光片90及镜头组件，所述芯片80设于所述电路板70的顶面，所述滤光片90固定在所述镜头组件之所述镜筒10的底面(即第二端面13)，所述镜筒10的底面连接至所述电路板70的顶面，所述芯片80与所述镜片20相对设置。镜筒10和电路板70之间设有支架17，支架17固定连接在电路板70和镜筒10之间，可以通过粘胶的方式实现支架17和电路板70之间，及支架17和镜筒10之间的固定。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
