具体实施方式
为了方便理解本申请实施例提供的摄像模组，首先说明一下其应用场景，该摄像模组应用于移动终端，如手机、平板电脑或者笔记本等常见的移动终端。如图1所示，图1示出了手机的结构示意图，该手机包括外壳200，以及设置在外壳200内的器件，其中，上述器件包括摄像模组300。在具体装配时，摄像模组300固定在外壳200内，且外壳200上设置有与该摄像模组300配合的第二通孔，以使得摄像模组300的镜头露出。为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
首先参考图2，图2示出了本申请实施例提供的摄像模组300的主体结构，该摄像模组300主要包括一个底座10以及与底座10固定连接的壳体20，如图2中所示，底座10与壳体20固定连接并形成一个容纳腔，摄像模组300的升降镜头30装配在该容纳腔中，且升降镜头30部分外露在壳体20外。
一并参考图2及图3，其中图3示出了摄像模组300的分解示意图。如图3所示，摄像模组300的底座10包括一个长方形的支撑板11，该支撑板11具有相对的两个表面，分别为第一表面及第二表面，其中，位于底座10第二表面的一侧设置了一个印刷电路板90，该印刷电路板90上设置了图像传感器91，该图像传感器91与印刷电路板90之间电连接。此外，支撑板11上设置有一个镂空结构15，该镂空结构15内镶嵌了滤光片80。在连接时，支撑板11与印刷电路板90之间固定连接，且滤光片80覆盖在图像传感器91。在图3中，镂空结构15及滤光片80采用矩形结构，但是应当理解的是，本申请实施例不限定滤光片80及镂空结构15的形状，在生产中，可以根据实际需要调整镂空结构15及滤光片80的结构，如可以采用圆形、椭圆形或者其他形状均可以。
继续参考图3，本申请实施例提供的摄像模组300还包括升降镜头30，该升降镜头30包括升降筒32以及固定在升降筒32的镜头33。如图3中所示，升降筒32采用一个圆形的筒体，且升降筒32的两端开口，镜头33也采用圆形的透镜，在装配时，镜头33镶嵌在升降筒32内，且位于升降筒32的一端。在将升降筒32装配在底座10上时，升降镜头30与底座10可相对滑动。具体结构可以参考图3，支撑板11上位于第一表面的一侧两个导向柱12，且两个导向柱12对称设置，在图3中两个导向柱12分列在镂空结构15两侧，并相对镂空结构15的轴线对称。升降镜头30滑动装配在两个导向柱12。在装配时，升降镜头30上设置有两个通孔(图中未标示)，两个导向柱12一一对应装配在两个通孔中。在升降镜头30滑动装配在底座10上时，升降镜头30可沿导向柱12的长度方向滑动，而在图3中导向柱12的长度方向垂直于支撑板11的第二表面，因此在升降镜头30沿导向柱12的长度方向滑动时，可以实现镜头33靠近图像传感器91以及远离图像传感。当然应当理解的是，本申请实施例提供的导向柱12的个数不局限于图3中所示的两个，还可以采用一个、三个、四个等不同的个数。在升降镜头30装配在导向柱12时，镜头33与图像处理器共轴设置，以保证摄像头的拍摄效果。
继续参考图3，本申请实施例提供的摄像模组300还包括壳体20，该壳体20与底座10固定连接并形成容驱动装置及升降镜头30的空间。如图3中所示，该壳体20为一个长方体结构且具有一个中空腔体，在与底座10固定连接时，可以采用螺栓或螺钉等螺纹连接件连接，或者还可以采用粘接、焊接的方式连接。并且支撑板11与壳体20围成容纳升 降装置及驱动装置的空间。此外，壳体20上还设置有一体第一通孔21，在升降镜头30与底座10之间滑动时，升降镜头30可穿过该第一通孔21外露在壳体20外。
继续参考图3，在本申请实施例提供的摄像模组300还包括驱动装置，该驱动装置用于驱动升降镜头30滑动。该驱动装置包括两部分：驱动机构60以及旋转筒40。如图3中所示，该旋转筒40为一个两端开口的筒体41，且旋转筒40与底座10可相对转动。在具体装配时，底座10的支撑板11上设置了一个两个相对的弧形凸起16，旋转筒40套装在该弧形凸起16上从而对旋转筒40径向进行限位，使得旋转筒40可以绕弧形凸起16转动。在具体设置该弧形凸起16时，两个弧形凸起16相对设置在镂空结构15的两侧，且弧形凸起16的内凹方向相对。此外，弧形凸起16位于导向柱12的外侧，在装配旋转筒40时，旋转筒40能够套装在升降镜头30的外侧。在嵌套后，旋转筒40与升降镜头30共轴设置并螺旋连接，如图3中所示，旋转筒40的内侧壁设置有内螺纹，升降镜头30设置有与内螺纹配合的外螺纹。在设置外螺纹时，如图3中所示，升降镜头30的升降筒32远离镜头33的一端设置有凸肩31，外螺纹设置在凸肩31上。在装配升降镜头30时，升降镜头30的凸肩31朝向支撑板11套装在导向柱12，之后旋入旋转筒40，使得旋转筒40的内螺纹与外螺纹配合，并将旋转筒40旋入到与支撑板11接触的位置，此时旋转筒40套装在弧形凸起16。在壳体20与底座10固定连接时，旋转筒40的上下两端分别抵压在壳体20以及支撑板11上，以保证旋转筒40的径向限位。在旋转筒40旋转时，由于旋转筒40不可轴向移动，因此通过内螺纹与外螺纹的配合可以驱动升降镜头30进行升降。如在旋转筒40向右旋转时，升降筒32可以向远离支撑板11的方向滑动，在旋转筒40向左旋转时，升降筒32可以向靠近支撑板11的方向滑动。当然除了上述内螺纹与外螺纹的配合，本申请实施提供的摄像模组还可以采用其他的方式来实现旋转筒驱动升降镜头。如旋转筒的内侧壁设置有螺旋滑槽，升降镜头设置有与螺旋滑槽滑动配合的螺旋滑块。更具的体，旋转筒内设置有三条、四条等至少两条螺旋滑槽，且在设置时，螺旋滑槽沿旋转筒的内侧壁螺旋上升，且均匀分布在旋转筒内，对应的升降镜头的升降筒内也设置有与每个螺旋滑槽滑动配合的螺旋滑块，通过螺旋滑块与螺旋滑轨的配合，在旋转筒转动时驱动升降镜头升降。
此外，在旋转筒40装配时，与底座10及壳体20之间不可避免的会产生装配间隙，因此为了限定旋转筒40的轴向运动，在旋转筒40与底座10之间设置有弹性片50或者在壳体20与旋转筒40之间设置有弹性片50。通过设置的弹性片50的弹力使得旋转筒40的一端抵压在壳体20上，或者抵压在支撑板11上，从而保证旋转筒40在轴向方向上的限位。保证驱动升降镜头30时的稳定性。同时，通过旋转筒40端面上设置的弹性片50，可降低旋转筒40与支撑板11或壳体20的摩擦力、消除两者之间的间隙，降低回程差。当然上述弹性片50的个数也可以设置两个，此时壳体20与旋转筒40之间，以及旋转筒40与支撑板11之间均设置有弹性片50，也可达到相同的效果。
继续参考图3，本申请实施例提供的驱动装置还包括一个驱动机构60，该驱动机构60用于驱动旋转筒40转动。如图3中所示，驱动机构60及升降镜头30位于底座10的同一侧。其具体结构包括一个驱动电机61，与驱动电机61连接的蜗杆62，以及设置在旋转筒40外侧壁的齿环42；其中，蜗杆62与齿环42啮合。当然也可以采用驱动电机连接齿轮减速器，再通过齿轮减速器与蜗杆连接，其中驱动电机与齿轮减速器的连接方式为常见的连接方式，在此不再赘述。
在具体装配时，如图3中所示，驱动电机61固定在底座10上，具体的支撑板11上设 置有一个弧形的安装槽13，驱动电机61横卧在安装槽13内并固定连接，具体可以采用粘接或者螺纹连接件(螺栓或螺钉)将驱动电机61固定在安装槽13内。此时，驱动电机61的输出轴的长度方向与旋转筒40转动所绕的轴线垂直，即驱动电机61的输出轴垂直于升降镜头30的滑动方向。驱动电机61的输出轴连接一个蜗杆62，对应的在旋转筒40的外侧壁设置有一圈齿环42，且齿环42与蜗杆62啮合。在驱动电机61转动时，通过蜗杆62与齿环42的配合，将水平转动转换成竖直转动，从而驱动旋转筒40转动，再通过旋转筒40转动带动升降镜头30升降。当然也可以采用驱动电机连接齿轮减速器，再通过齿轮减速器与蜗杆连接，其中驱动电机与齿轮减速器的连接方式为常见的连接方式，在此不再赘述。
由上述结构可以看出，在本申请实施例中，采用升降镜头30伸出结构，导向柱12穿过底座10，驱动装置设置在升降镜头30外围，以实现伸出部分尺寸最小化，并且驱动装置与升降镜头30位于支撑板11的同一侧，而且还可以与升降镜头30之间在高度方向部分重叠，相比与现有技术中的升降镜头30与驱动装置单独占用空间，可以减少摄像模组300占用的空间，便于移动终端的小型化发展。
继续参考图3，在驱动电机61与底座10固定连接时，印刷电路板90上设置有电机驱动IC100，该电机驱动IC100与驱动电机61连接，并且可以通过电机驱动IC100来驱动驱动电机61正传或者反转，从而可以驱动升降镜头30进行升降。在移动终端上，摄像模组300在未拍摄时，升降镜头30缩回到移动终端以内，不影响移动终端总体厚度；在拍摄时，升降镜头30伸出到移动终端本体以外，提升光学可用空间，实现图像高品质拍摄。
此外，为了检测升降镜头30的位置，可以在升降镜头30设置有磁性件，在导向柱为至少一个时，可以在其中的一个导向柱12设置有检测磁性件的检测器件，或者在部分或者全部导向柱12上设置该检测器件；在导向柱为至少一个时，可以在一个导向柱12设置有磁性件，或者部分或者全部导向柱12上设置检测器件；升降镜头30设置有检测磁性件的检测器件。其中的磁性件可以为磁石72，检测器件可以为霍尔传感器71。如图3所示，霍尔传感器71可安装在其中一根导向柱12上，磁石72安装在升降筒32上，并且与霍尔传感器71平行相对，升降筒32及镜头33做上下运动时会带动磁石72运动，霍尔传感器71通过感测磁场的变化确定镜头33的位置信息。此外，印刷电路板90与霍尔传感器71连接，从而可以接收霍尔传感器71的信号，进而获取升降镜头30的位置信息。由上述描述可以看出，底座10上伸出的导向柱12，即可以保证升降筒32做直线运动，同时也实现了霍尔传感器71的安装固定闭环控制，节省了体积和成本。
在升降镜头30穿过壳体的第一通孔外露时，升降镜头30与壳体之间存在间隙，为了改善摄像镜头30的密封效果。升降镜头30与第一通孔密封连接。通过升降镜头30与第一通孔之间的密封，避免外界的液体或水汽进入到摄像模组内。如图4所示，在第一通孔内镶嵌有密封圈22，密封圈22与升降镜头30接触的一面设置有环形凹槽222。具体的，密封圈22镶嵌在第一通孔的侧壁上，且密封圈22具有套装在第一通孔的侧壁上的安装槽，安装槽的两个侧壁分别卡装在第一通孔的侧壁的两个端面，且密封圈22朝向升降镜头30的一面也设置了环形凹槽222，该环形凹槽222将密封圈22与升降镜头30接触的一端切割成两部分，为方便描述将其命名为第一接触部221及第二接触部223，且第一接触部221及第二接触部223分别与升降镜头30的升降筒密封接触。在密封时，第一接触部221及第二接触部223均发生形变，从而使得密封圈22对升降镜头30形成双层密封，提高了密 封效果。
如图5所示，为进一步改善密封效果。升降镜头30外露在壳体外的一端设置有凸肩321，凸肩321与密封圈22可密封接触。在升降镜头30回缩到初始位置时，凸肩321抵压在密封圈22的端面从而形成与密封圈22在轴向以及径向两个方向的密封。在一个可实施的方案中，还可以在密封圈22朝向凸肩321的一面设置一圈环形的凸起，凸肩321挤压凸起发生形变。或者还可以在凸肩321上设置有与该凸起配合的一圈环形的凹槽，通过凸起与凹槽的配合实现对升降镜头30的密封。
如图6所示，图6示出了本申请实施例提供的另一种摄像模组300的分解示意图。其中图6中相同的标号可以参考图3中相同标号。图6与图3的区别在与驱动机构60不同。在图6中，驱动机构60及升降镜头30位于底座10的同一侧。该驱动机构60包括固定在底座10的驱动电机61，与驱动电机61连接的齿轮63，以及设置在旋转筒40外侧壁的齿环42；其中，齿轮63与齿环42啮合。当然也可以采用驱动电机连接齿轮减速器，再通过齿轮减速器与齿轮连接，其中驱动电机与齿轮减速器的连接方式为常见的连接方式，在此不再赘述。
继续参考图6，在驱动电机61固定时，支撑板11上设置了圆形的安装槽14，驱动电机61可以采用粘接或者螺纹连接件(螺栓或螺钉)将驱动电机61固定在安装槽14内。此时，驱动电机61的输出轴的长度方向与旋转筒40转动所绕的轴线平行，即驱动电机61的输出轴垂平行于升降镜头30的滑动方向。驱动电机61的输出轴连接一个齿轮63，对应的在旋转筒40的外侧壁设置有一圈齿环42，且齿环42与齿轮63啮合。在驱动电机61转动时，通过齿轮63与齿环42的配合驱动旋转筒40转动，再通过旋转筒40转动带动升降镜头30升降。
如图6所述的摄像模组的密封可以参考图6及图5中所示的密封结构，在此不再详细赘述。
由上述结构可以看出，在本申请实施例中，采用升降镜头30伸出结构，导向柱12穿过底座10，驱动装置设置在升降镜头30外围，以实现伸出部分尺寸最小化，并且驱动装置与升降镜头30位于支撑板11的同一侧，而且还可以与升降镜头30之间在高度方向部分重叠，相比与现有技术中的升降镜头30与驱动装置单独占用空间，可以减少摄像模组300占用的空间，便于移动终端的小型化发展。
如图7所示，图7示出了本申请实施例提供的另一种摄像模组300的分解示意图。其中图4中相同的标号可以参考图3中相同标号。图7与图3的区别在与驱动机构60不同。在图7中，驱动机构60及升降镜头30位于底座10的同一侧。其具体结构包括相对而置的两个驱动电机61，与两个电机分列连接的蜗杆62，以及设置在旋转筒40外侧壁的齿环42；其中，蜗杆62与齿环42啮合。当然也可以采用驱动电机连接齿轮减速器，再通过齿轮减速器与蜗杆连接，其中驱动电机与齿轮减速器的连接方式为常见的连接方式，在此不再赘述。
在具体装配时，如图7中所示，驱动电机61固定在底座10上，具体的支撑板11上设置有一个弧形的安装槽13，驱动电机61横卧在安装槽13内并固定连接，具体可以采用粘接或者螺纹连接件(螺栓或螺钉)将驱动电机61固定在安装槽13内，且两个驱动电机61的输出轴相对而置。驱动电机61的输出轴的长度方向与旋转筒40转动所绕的轴线垂直，即驱动电机61的输出轴垂直于升降镜头30的滑动方向。驱动电机61的两个输出轴分别 连接在蜗杆62的两端，且三者之间同轴设置。旋转筒40的外侧壁设置有一圈齿环42，该齿环42与蜗杆62啮合。在驱动电机61转动时，两个驱动电机61同时带动蜗杆62转动，且通过蜗杆62与齿环42的配合，将水平转动转换成竖直转动，以驱动旋转筒40转动，再通过旋转筒40转动带动升降镜头30升降。
如图7所述的摄像模组的密封可以参考图4及图5中所示的密封结构，在此不再详细赘述。
由上述结构可以看出，在本申请实施例中，采用升降镜头30伸出结构，导向柱12穿过底座10，驱动装置设置在升降镜头30外围，以实现伸出部分尺寸最小化，并且驱动装置与升降镜头30位于支撑板11的同一侧，而且还可以与升降镜头30之间在高度方向部分重叠，相比与现有技术中的升降镜头30与驱动装置单独占用空间，可以减少摄像模组300占用的空间，便于移动终端的小型化发展。并且在图7所示的结构中，由于采用两个驱动电机61，因此，可以提供较大的输出扭矩，提高了驱动效果，同时采用两个驱动电机61可以降低每个驱动电机61的负载，提升驱动电机61的使用寿命。
如图8所示，图8示出了本申请实施例提供的第四种摄像模组，摄像模组300的底座10包括一个长方形的支撑板11，该支撑板11具有相对的两个表面，分别为第一表面及第二表面，其中，位于底座10第二表面的一侧设置了一个印刷电路板90，该印刷电路板90上设置了图像传感器91，该图像传感器91与印刷电路板90之间电连接。此外，支撑板11上设置有一个镂空结构15，该镂空结构15内镶嵌了滤光片80。在连接时，支撑板11与印刷电路板90之间固定连接，且滤光片80覆盖在图像传感器91。在图8中，镂空结构15及滤光片80采用矩形结构，但是应当理解的是，本申请实施例不限定滤光片80及镂空结构15的形状，在生产中，可以根据实际需要调整镂空结构15及滤光片80的结构，如可以采用圆形、椭圆形或者其他形状均可以。
继续参考图8，本申请实施例提供的摄像模组300还包括升降镜头30，该升降镜头30包括升降筒32以及固定在升降筒32的镜头33。如图8中所示，升降筒32采用一个圆形的筒体，且升降筒32的两端开口，镜头33也采用圆形的透镜，在装配时，镜头33镶嵌在升降筒32内，且位于升降筒32的一端。在将升降筒32装配在底座10上时，升降镜头30与底座10可相对滑动。具体结构可以参考图8，支撑板11上位于第一表面的一侧两个导向柱12，且两个导向柱12对称设置，在图8中两个导向柱12分列在镂空结构15两侧，并相对镂空结构15的轴线对称。升降镜头30滑动装配在两个导向柱12。在装配时，升降镜头30上设置有两个通孔(图中未标示)，两个导向柱12一一对应装配在两个通孔中。在升降镜头30滑动装配在底座10上时，升降镜头30可沿导向柱12的长度方向滑动，而在图8中导向柱12的长度方向垂直于支撑板11的第二表面，因此在升降镜头30沿导向柱12的长度方向滑动时，可以实现镜头33靠近图像传感器91以及远离图像传感。当然应当理解的是，本申请实施例提供的导向柱12的个数不局限于图8中所示的两个，还可以采用一个、三个、四个等不同的个数。在升降镜头30装配在导向柱12时，镜头33与图像处理器共轴设置，以保证摄像头的拍摄效果。

继续参考图8，在本申请实施例提供的摄像模组300还包括驱动装置，该驱动装置用于驱动升降镜头30滑动。该驱动装置包括可相对底座10滑动并用于驱动升降镜头升降的驱动块66；驱动驱动块66滑动的驱动机构。如图8中所示，驱动机构包括一个固定在底座的驱动电机以及与驱动电机连接的丝杠62，其中，该丝杠62穿设在驱动块66上并与驱动块66螺纹连接。驱动块66滑动装配在支撑板11的第一表面，如图8中所示，底座10的第一表面分别设置有安装驱动电机61的凹槽(图中未标示)，以及与驱动块66滑动装配的滑槽(图中未标示)。在驱动电机61转动时，带动驱动块在滑槽滑动。此外，在驱动块与升降镜头30连接时，驱动块66设置有相对升降镜头30滑动方向倾斜的直线滑槽65，升降镜头30设置有滑动装配在直线滑槽65内的滑块34。在驱动块66水平滑动时，通过直线滑槽65与滑块34的配合将驱动块66的水平滑动转换为升降镜头30的竖直运动。当然也可以采用驱动电机连接齿轮减速器，再通过齿轮减速器与丝杠连接，其中驱动电机与齿轮减速器的连接方式为常见的连接方式，在此不再赘述。
由上述结构可以看出，在本申请实施例中，采用升降镜头30伸出结构，导向柱12穿过底座10，驱动装置设置在升降镜头30外围，以实现伸出部分尺寸最小化，并且驱动装置与升降镜头30位于支撑板11的同一侧，而且还可以与升降镜头30之间在高度方向部分重叠，相比与现有技术中的升降镜头与驱动装置单独占用空间，可以减少摄像模组300占用的空间，便于移动终端的小型化发展。
继续参考图8，在驱动电机61与底座10固定连接时，印刷电路板90上设置有电机驱动IC100，该电机驱动IC100与驱动电机61连接，并且可以通过电机驱动IC100来驱动驱动电机61正传或者反转，从而可以驱动升降镜头30进行升降。在移动终端上，摄像模组300在未拍摄时，升降镜头30缩回到移动终端以内，不影响移动终端总体厚度；在拍摄时，升降镜头30伸出到移动终端本体以外，提升光学可用空间，实现图像高品质拍摄。
此外，为了检测升降镜头30的位置，可以在升降镜头30设置有磁性件，在导向柱为至少一个时，可以在其中的一个导向柱12设置有检测磁性件的检测器件，或者在部分或者全部导向柱12上设置该检测器件；在导向柱为至少一个时，可以在一个导向柱12设置有磁性件，或者部分或者全部导向柱12上设置检测器件；升降镜头30设置有检测磁性件的检测器件。其中的磁性件可以为磁石，检测器件可以为霍尔传感器。霍尔传感器可安装在其中一根导向柱12上，磁石安装在升降筒32上，并且与霍尔传感器平行相对，升降筒32及镜头33做上下运动时会带动磁石运动，霍尔传感器通过感测磁场的变化确定镜头33的位置信息。此外，印刷电路板90与霍尔传感器连接，从而可以接收霍尔传感器的信号，进而获取升降镜头30的位置信息。由上述描述可以看出，底座10上伸出的导向柱12，即可以保证升降筒32做直线运动，同时也实现了霍尔传感器的安装固定闭环控制，节省了体积和成本。
在升降镜头穿过壳体的第一通孔外露时，升降镜头与壳体之间存在间隙，为了改善摄像镜头的密封效果。升降镜头与第一通孔密封连接。通过升降镜头与第一通孔之间的密封，避免外界的液体或水汽进入到摄像模组内。具体的密封结构可以参考图4及图5中的相关描述。
本申请实施例还提供了一种移动终端，该移动终端包括外壳以及上述任一项的摄像模 组，其中，摄像模组的底座固定在外壳内。如手机、平板电脑或者笔记本等常见的移动终端。如图1所示，图1示出了手机的结构示意图，该手机包括外壳200，以及设置在外壳200内的器件，其中，上述器件包括摄像模组300。在具体装配时，摄像模组300的底座10固定在外壳200内，且外壳200上设置有与该摄像模组300的升降镜头配合的第二通孔，在升降镜头上升时，升降镜头穿过第二通孔后露出，以使得摄像模组的镜头露出。在使用时，通过驱动机构驱动旋转筒转动，并且通过旋转筒带动升降镜头进行升降，从而可以改善摄像模组的拍摄效果。并且在采用上述结构时，旋转筒套装在升降镜头外，从而使得驱动装置部分与升降镜头重叠，从而降低了摄像模组的体积，便于移动终端的小型化发展。
在一个更具体的实施方案中，外壳可以与壳体为一体结构，此时升降镜头与移动终端的外壳密封连接，从而增强整个移动终端的密封效果。
以上，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申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
