具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。请同时参见图1和图2，图1是本公开实施例提供的一种摄像装置100的立体结构示意图；图2是图1中摄像装置100沿A-A线的剖面结构示意图，如图1和图2所示，上述摄像装置100包括支架座10、摄像电路板20、第一摄像组件30以及第二摄像组件40，所述支架座10设置有容置腔；所述摄像电路板20设置于所述容置腔内，且所述摄像电路板20将所述容置腔分割成第一容置腔101和第二容置腔102；所述第一摄像组件30设置于所述第一容置腔101内，所述第二摄像组件40设置于所述第二容置腔102内；
所述第一摄像组件30包括第一镜头31以及第一图像传感器32，所述第一图像传感器32贴设于所述摄像电路板20的第一侧面；所述第一图像传感器32接收穿过所述第一镜头31的入射光成像；
所述第二摄像组件40包括第二镜头41以及第二图像传感器42，所述第二图像传感器42贴设于所述摄像电路板20的第二侧面，所述第二侧面与所述第一侧面相对设置；所述第二图像传感器42接收穿过所述第二镜头41的 入射光成像。
本公开实施例中，第一摄像组件30和第二摄像组件40设置于支架座10内，可以实现第一摄像组件30和第二摄像组件40的拍摄方向相反，则将摄像装置100安装于移动终端等电子设备的主电路板上时，仅需在主电路板上开设一个与摄像装置100的配合的安装孔，从而通过第一摄像组件30和第二摄像组件40实现该电子设备的前、后置摄像头的功能，与相关技术中前、后置摄像头分别采用两个摄像头模组的方式相比，减少了前、后置摄像头在电子设备上所占用的空间，提高整机空间利用率，增加整机器件在电路板上的堆叠灵活性。
其中，所述第一摄像组件和所述第二摄像组件可以是定焦式摄像头结构，此时，上述支架座10可以是贯穿设置有上述容置腔的固定的支架座，且摄像电路板20、第一摄像组件30以及第二摄像组件40固定于容置腔内，从而使第一摄像组件30以及第二摄像组件40仅能以固定的焦距拍摄。
或者，所述第一摄像组件和所述第二摄像组件还可以是变焦式摄像头结构，如图3所示，上述摄像装置100还可以包括第一驱动马达11，所述第一驱动马达11设置于所述容置腔内，且所述第一驱动马达11可带动所述第一镜头31和所述第二镜头41运动。
本实施方式中，第一驱动马达11可同时带动第一摄像组件30和第二摄像组件40运动，从而可以分别实现第一镜头31和第二镜头41的变焦拍摄，即当第一驱动马达11带动第一镜头31和第二镜头41运动时，若第一摄像组件30处于拍摄模式，则可以使第一摄像组件30拍摄的焦距发生变化；而若第二摄像组件40处于拍摄模式，则可以使第二摄像组件40拍摄的焦距发生变化，结构简单，且提升拍摄质量。上述方案，将第一镜头的驱动马达与第二镜头的驱动马达集成为一体，用一个驱动马达来实现两个摄像组件的调焦目的，这样，一体式的驱动马达设计有利于减小整个该摄像装置的高度。
当然，在其他实施例中，所述第一摄像组件和所述第二摄像组件还可以是单独采用不同的驱动马达来进行调焦，如图4所示，上述摄像装置100还可以包括第二驱动马达12和/或第三驱动马达13：
所述第二驱动马达12设置于所述第一容置腔101，且所述第二驱动马达 12可带动所述第一镜头31运动；
所述第三驱动马达13设置于所述第二容置腔102，且所述第三驱动马达13可带动所述第二镜头41运动。
其中，当第一摄像组件30处于拍摄模式时，第二驱动马达12可以带动第一镜头31运动，从而实现第一摄像组件30拍摄时的焦距变化；而当第二摄像组件40处于拍摄模式时，第三驱动马达13可以带动第二镜头41运动，从而实现第二摄像组件40拍摄时的焦距变化，因而通过两个驱动马达可以分别实现第一摄像组件30以及第二摄像组件40拍摄时的焦距调节，调焦方便且稳定性高。
应当说明的是，上述摄像装置100中，可以是仅第一摄像组件30或者第二摄像组件40具备调焦功能，即若仅第一摄像组件30具备调焦功能，则摄像装置100仅设置有第二驱动马达12；若仅第二摄像组件40具备调焦功能，则摄像装置100仅设置有第三驱动马达13；当然，也可以是第一摄像组件30和第二摄像组件40均具备调焦功能，即摄像装置100中设置有第二驱动马达12和第三驱动马达13。
另外，在上述摄像装置100设置有第二驱动马达12的情况下，摄像装置100中也还可以设置有第一驱动马达11，第一驱动马达11驱动第二镜头41运动，且与第二驱动马达12共同驱动所述第一镜头31运动；同理，也可以是上述摄像装置100同时设置有第一驱动马达11和第三驱动马达13，甚至于同时设置有第一驱动马达11、第二驱动马达12和第三驱动马达13，在此并不进行限定。
本公开实施例中，上述摄像电路板20用于承载第一图像传感器31和第二图像传感器42，上述摄像电路板20与电子设备的主电路板连接，摄像电路板20上的线路可以将第一图像传感器31以及第二图像传感器42传输至电子设备的主电路板上的其他元件(如处理器等)。
上述摄像电路板20与电子设备的主电路板连接，如图5所示，可以是上述摄像装置100还包括连接电路板50，所述连接电路板50穿过所述支架座10的侧壁与所述摄像电路板20连接，所述摄像电路板20通过所述连接电路板50与外部电路电连接，从而降低安装难度，且使摄像电路板20与外部电 路的连接稳定可靠。
其中，上述连接电路板50穿过支架座10的侧壁与摄像电路板20连接，可以是通过在支架座10的侧壁上开设供连接电路板50穿过的通孔实现，在此并不进行限定。
应当说明的是，上述连接电路板50可以是任意一种电路板，仅需实现摄像电路板20与外部电路电连接，例如：上述连接电路板50可以是柔性电路板(Flexible Printed Circuit，FPC)，具备厚度薄以及弯折性好等优点，从而使摄像电路板20与外部电路的连接更稳定可靠。
其中，摄像电路板20可以通过连接电路板50将第一摄像组件30以及第二摄像组件40的电信号传输至主电路板，连接电路板50上需要设置传输第一摄像组件30以及第二摄像组件40的电信号的线路，因而为了避免因设置线路而使连接电路板50的宽度过大，连接电路板50可以设置为双层或者多层FPC。
另外，上述摄像电路板20也可以是任意一种能够实现承载第一图像传感器31以及第二图像传感器42，且传输第一图像传感器31的电信号以及第二图像传感器42的电信号的电路板，如图6所示，上述摄像电路板20也可以包第一电路板21、第二电路板22以及导热层23；所述第一图像传感器31贴设于所述第一电路板21上；所述第二图像传感器42贴设于所述第二电路板22上；所述导热层23设置于所述第一电路板21与所述第二电路板22之间，通过第一电路板21可以实现承载第一图像传感器31，且传输第一图像传感器31的电信号，以及通过第二电路板22可以实现承载第二图像传感器42，且传输第二图像传感器42的电信号。
应当说明的是，上述第一电路板21与上述第二电路板22之间设置导热层23(如导热硅胶或者石墨、铜箔等高性能散热材料等)，可以提升摄像电路板20的散热性能，提高摄像装置100的使用寿命。
上述方案中，所述摄像电路板20是采用两块电路板(即第一电路板21和第二电路板22)来实现，当然，所述摄像电路板20也可以利用一块电路板来实现，此时，上述摄像电路板20可以为双层或多层电路板，且所述多层电路板内设置有多层铜层。这样，采用一块电路板作为所述摄像电路板，与 上述采用两块电路板作为所述摄像电路板的方式相比，省去了一层电路板，及两块电路板之间的间隙，可以进一步缩小摄像电路板20的厚度，使得整个摄像装置结构更加紧凑，从而进一步缩小摄像装置100在电子设备内占据的安装空间，提高了整个摄像装置的实用性和适应性；且多层电路板内设置有多层铜层，可以提高摄像电路板20的导热性能。
本公开实施例中，第一镜头31和第二镜头41分别设置于摄像电路板20的两侧，可以是第一镜头31和第二镜头41正对设置于摄像电路板20的两侧，从而可以进一步缩小摄像装置100在电子设备的主电路板上占据的安装空间。
当然，如图7a和图7b所示，上述第一镜头31和上述第二镜头41也可以是交错设置于所述摄像电路板20的两侧，从而使第一镜头31和第二镜头41的位置分布更灵活。
应当说明的是，当上述第一镜头31和第二镜头41交错设置时，上述第一镜头31和第二镜头41可以是同时设置于一个驱动马达内，从而实现分别对第一摄像组件30和第二摄像组件40的调焦；或者，也可以是第一镜头31和第二镜头41分别设置于一个驱动马达内，通过两个驱动马达分别实现对第一摄像组件30和第二摄像组件40的调焦；或者，还可以是上述支架座10仅包括一个驱动马达，且第一镜头31或者第二镜头41设置于该驱动马达内，从而实现第一摄像组件30和第二摄像组件40中的一个摄像组件拍摄时可调焦，而另一个拍摄时定焦，在此并不进行限定。
本公开实施例中，为了提高第一摄像组件30以及第二摄像组件40的拍摄质量，如图8所示，所述第一摄像组件30还可以包括第一滤光片支架61以及第一滤光片62，所述第一滤光片支架61设置于所述第一镜头31与所述摄像电路板20之间，且所述第一滤光片支架61支撑所述第一滤光片62；所述第一镜,31接收的入射光经过所述第一滤光片62传输至所述第一图像传感器32；以及，所述第二摄像组件40还包括第二滤光片支架71以及第二滤光片72，所述滤光片支架71设置于所述第二镜头41与所述摄像电路板20之间，且所述第二滤光片支架71支撑所述第二滤光片72；所述第二镜头41接收的入射光经过所述第二滤光片72传输至所述第二图像传感器42，从而通过第一滤光片62可以提升第一摄像组件30拍摄的图像质量，以及通过第二 滤光片72可以提升第二摄像组件40拍摄的图像质量。
当然，上述摄像装置100也可以是第一摄像组件30中设置有第一滤光片支架61以及第一滤光片62，而第二摄像组件40中未设置第二滤光片支架71以及第二滤光片72；或者，第二摄像组件40中设置有第二滤光片支架71以及第二滤光片72，而第一摄像组件30中未设置第一滤光片支架61以及第一滤光片62，在此并不进行限定。
另外，如图9a所示，所述第一摄像组件30还可以包括第三滤光片81，所述第三滤光片81设置于所述第一镜头31内，且所述第一镜头31接收的入射光经过所述第三滤光片81传输至所述第一图像传感器32；以及，所述第二摄像组件40还可以包括第四滤光片82，所述第四滤光片82设置于所述第二镜头41内，且所述第二镜头41接收的入射光经过所述第四滤光片82传输至所述第二图像传感器42，这样，不仅可以通过第三滤光片81提升第一摄像组件30拍摄的图像质量，以及通过第四滤光片82提升第二摄像组件40拍摄的图像质量；另外，由于第三滤光片81设置于第一镜头31内，可以避免第三滤光片81占据第一镜头31与第一图像传感器32之间的空间，可以使第一镜头31与第一图像传感器32之间设置的间距更小，缩小第一摄像组件30的体积，从而实现缩小摄像装置100的厚度H的大幅缩小；同理，第四滤光片82设置于第二镜头41内，也可以实现第二镜头41与第二图像传感器42之间的间距缩小，使得摄像装置100的厚度缩小，进一步减小摄像装置100在电子设备中占据的安装空间。
另外，由于将滤光片集成与镜头中已为本领域所熟知的加工方案，采用这种方式还可以降低各摄像组件设计的复杂程度，降低开发难度、提升产品良率以及节约生产成本等。
应当说明的是，上述上摄像装置100也可以是第一摄像组件30中设置有第三滤光片81，而第二摄像组件40中未设置有第四滤光片82；或者第二摄像组件40中设置有第四滤光片82，而第一摄像组件30中未设置有第三滤光片81，这样，在一定程度上也可以缩小摄像装置100的厚度H，实现减小摄像装置100在电子设备中占据的安装空间。
例如：若仅需要第一摄像组件30(可以是前置摄像头)实现人脸红外识 别功能，则可以仅在第一镜头31内设置第三滤光片81，且第三滤光片81可以滤除除红光以外的色光，如图9b中所示；当然，若仅需要第二摄像组件40(可以是后置摄像头)实现人脸红外识别功能，同理可以在第二镜头41内设置可滤除除红外光以外的色光的滤光片。
本公开实施例的摄像装置100，包括：支架座、摄像电路板、第一摄像组件以及第二摄像组件，支架座设置有容置腔；摄像电路板设置于容置腔内，且摄像电路板将容置腔分割成第一容置腔和第二容置腔；第一摄像组件设置于第一容置腔内，第二摄像组件设置于第二容置腔内；第一摄像组件包括第一镜头以及第一图像传感器，第一图像传感器贴设于摄像电路板的第一侧面；第一图像传感器接收穿过第一镜头的入射光成像；第二摄像组件包括第二镜头以及第二图像传感器，第二图像传感器贴设于摄像电路板的第二侧面，第二侧面与第一侧面相对设置；第二图像传感器接收穿过第二镜头的入射光成像。这样，本公开所提供的摄像装置，将第一、第二摄像组件集成，且第一、第二摄像组件的镜头方向相反，应用于移动终端时，可分别作为移动终端的前置摄像头和后置摄像头，与相关技术前、后置摄像头分别采用两个摄像头模组的方式相比，减少了前、后置摄像头在移动终端上所占用的空间，提高整机空间利用率，增加整机器件在电路板上的堆叠灵活性。
基于上述摄像装置100，本公开实施例还提供一种移动终端，包括上述摄像装置100。
由于移动终端本体的结构是相关技术，摄像装置100在上述实施例中已进行详细说明，因此，本实施例中对于具体的移动终端的结构不再赘述。
本公开实施例中，上述移动终端可以是任何设置有上述摄像装置100的移动终端，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等。
上面结合附图对本公开的实施例进行了描述，但是本公开并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本公开的启示下，在不脱离本公开宗旨和权利要求 所保护的范围情况下，还可做出很多形式，均属于本公开的保护之内。
