具体实施方式：
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1和图2，摄像头装置100包括镜头组件10、驱动器20和感光组件40，所述驱动器20用于驱动所述镜头组件10以调整所镜头组件10的焦距，所述感光组件40设置在所述镜头组件10的底部。所述感光组件40包括滤波片41、感光芯片42、第一电路板43和第二电路板44。所述第一电路板43上开设通槽434，所述感光芯片42收容在所述通槽434内。所述滤波片41固定在所述第一电路板43一侧并覆盖所述通槽434。所述第二电路板44固定在所述第一电路板43背离所述滤波片41的一侧并与所述第一电路板43电连接，所述感光芯片42与所述第二电路板44电连接。
所述摄像头装置100包括一安装座30，所述安装座30固定设置在所述第一电路板43上并架设于所述滤波片41上方。所述镜头组件10和所述驱动器20设置在所述安装座30上，所述驱动器20与所述第一电路板43电连接。具体地，所述安装座30的上端面设置第一固定件31，所述驱动器20通过所述第一固定件31固定安装在所述安装座30上。所述安装座30的下端面通过第二固定件431固定设置所述第一电路板43上。在一实施例中，所述第一固定件31和所述第二固定件431可以是粘合胶、热熔胶等，使所述第一电路板43、所述驱动器20和所述安装座30之间通过粘接固定。
所述安装座30上开设安装槽33，所述安装槽33贯穿所述安装座30，所述滤波片41位于所述安装槽33下方。所述驱动器20具有与所述安装槽33连通的内腔21，所述镜头组件10与所述驱动器20传动连接并安装在所述驱动器20的内腔21中。所述驱动器20可以驱动所述镜头组件10在所述内腔21和所述安装槽33组成的空间内上下移动。所述安装座30的侧边还开设有凹槽32，部分第一电路板43从所述凹槽32露出。所述驱动器20下端设置有对应所述凹槽32的支脚22，所述驱动器20固定在所述安装座上时，所述支脚22收容在所述凹槽32内并抵触所述第一电路板43。所述驱动器20可以通过所述支脚22与所述第一电路板43电连接。
请参阅图3和图4，所述第一电路板43上的通槽434的边缘设置第三固定件432，所述滤波片41通过所述第三固定件432固定设置在所述第一电路板43上并覆盖所述通槽434。在一实施例中，所述第三固定件432可以是粘合胶、热熔胶等，使所述第一电路板43和所述滤波片41之间通过粘接固定。所述第二电路板44大致呈方框形，通过一连接件45(见图6)设置于所述第一电路板43的底部。在一实施例中，所述第二电路板44优选为一柔性电路板，所述连接件45为导电胶，优选为各向异性导电胶膜(Anisotropic conductive film,ACF)，所述第二电路板44通过所述连接件45与所述第一电路板电连接。ACF胶只在Z方向上导电，而X，Y方向上不导电，即只在图6视角的竖直方向上导电，不在水平方向上导电，从而避免第一电路板43与第二电路板44的侧边接触发生短路。在另一实施例中，所述第一电路板43和所述第二电路板44通过镀铜等技术进行电连接，所述连接件45为可以进行镀铜或锡焊的电连接件。
所述感光芯片42边缘设置第一电连接部422，所述第二电路板44上设置有对应所述第一电连接部422的第二电连接部441。所述感光芯片42通过至少一根导线421与所述第二电路板44电连接。所述第一电连接部422和所述第二电连接部441均包括多个电路接口，所述导线421的两端分别焊接于所述第一电连接部422和所述第二电连接部441上对应的电路接口处。
请继续参阅图5和图6，所述摄像头装置100还包括第一盖板46，所述第一盖板46固定设置在所述第二电路板44背离所述第一电路板43的一侧，即所述第二电路板44的底面。收容在所述通槽434内的所述感光芯片42固定设置在所述第一盖板46上对应所述通槽434的区域。在一实施例中，所述第一盖板46可以是一钢板或其他金属板，覆盖在所述摄像头装置100的底部，保护所述摄像头装置100的内部结构的同时，还用于散失所述感光芯片42产生的热量。除金属材料外，所述第一盖板46还可以由其他高强度材料制成。所述感光芯片42可以通过热熔胶或粘合胶等贴附于所述第一盖板46表面，在其他实施例中，所述感光芯片42还可以通过焊接或表面贴片技术等固定设置在所述第一盖板46上。
贴附在所述第一盖板46上所述感光芯片42容置在所述通槽434和所述第二电路板44的中心通孔组成的空间内，所述导线421也收容在所述通槽434内。换句话说，所述感光芯片42上端面低于所述第一电路板43的上端面，所述导线421的最高点低于所述第一电路板43的上端面。在传统技术方案中，感光芯片42和导线421直接设置在第一电路板43表面，滤波片41不得不与第一电路板43间隔设置。本申请的技术方案通过将感光芯片42和导线421设置在第一电路板43上的通槽内，再利用第二电路板44降低所述感光芯片与所述第一电路板的电连接位置以降低所述导线421的最高点，使得所述滤波片41可以直接设置于所述第一电路板43上，消除所述滤波片41与所述第一电路板43之间的距离，达到减少摄像头装置100的厚度尺寸的目的，无需另外设置滤波片41的支架和预留所述感光芯片42及其导线421的安装空间，将摄像头装置100的厚度尺寸至少减少0.36mm。
请再次参阅图1和图2，所述摄像头装置100还包括一电连接组件50，用于连接外部电源或电设备。所述电连接组件50包括第三电路板51、第二盖板52和电连接器53。所述第三电路板51通过一连接板433电连接于所述第一电路板43。所述第二盖板52贴附于所述第三电路板51的一侧，用于保护所述第三电路板51。所述电连接器53设置在所述第三电路板51背离所述第二盖板52的一侧，所述电连接组件50通过所述电连接器53与外部电源或电设备连接。
请参阅图7，本申请还提供一种移动终端200，所述移动终端包括处理器201和上述摄像头装置100。所述处理器201电连接所述摄像头装置100的电连接组件50，以控制所述摄像头装置100。
以上实施方式仅用以说明本发明的技术方案而非限制，尽管参照以上较佳实施方式对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或等同替换都不应脱离本发明技术方案的精神和范围。
