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，或一体地连接，可以是机械连接，也可以是电连接，可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。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。
参考图1a、图1b所示，根据本申请的一个实施例，提供了一种电子设备，该电子设备包括摄像头模组1、第一驱动机构15及壳体2，壳体2 形成第一腔体21，摄像头模组1设置于第一腔体21内，壳体2上开设有开口，第一驱动机构15驱动摄像头模组1沿第一方向移动以使摄像头模组1从开口伸出，摄像头模组1包括镜头组件11、图像传感器、弹性件16和第二驱动机构18，弹性件16设置于镜头组件11和图像传感器之间，在摄像头模组1位于第一腔体21内的情况下，弹性件16处于压缩状态，镜头组件11与图像传感器之间的距离为第一距离，在摄像头模组1从开口伸出的情况下，弹性件16处于伸展状态，镜头组件11与图像传感器之间的距离大于第一距离，第二驱动机构18驱动镜头组件11在第二方向移动以调整镜头组件11的成像焦距。
第一方向例如为图1a、图1b中所示的上下方向，第二方向例如为图1a、图1b中所示的左右方向。当然，第一方向和第二方向并不限于图1a、图1b中所示的方向，第一方向和第二方向可以是相互垂直的两个方向，还可以是相同的方向。第二方向是摄像头模组1在调焦对焦过程中镜头组件11移动的方向，即镜头组件11接收外界光线入射的方向，镜头组件11在第二方向移动以达到调整成像焦距的目的。在本申请实施例提供的电子设备中，首先由于设置了第一驱动机构15，因此摄像头模组1可以在第一驱动机构15的驱动作用下沿第一方向移动以从壳体2的开口处伸出到壳体2的外部。并且，由于设置了弹性件16，在摄像头模组1从壳体2内伸出到壳体2的外部后，弹性件16从压缩状态转变为伸展状态，即从图1a所示的状态转变为图1b所示的状态，由此，镜头组件11与图像传感器之间的距离得以增大，因此，当第二驱动机构18驱动镜头组件11在第二方向移动以对镜头组件11的成像焦距进行调整时，镜头组件11的可移动距离得以增大，从而实现了更大范围的调焦对焦距离，由此可以实现通过一个摄像头模组进行正常拍摄、微距拍摄及长焦拍摄的功能，在减少摄像头模组数量的同时不会降低拍照的质量，从而能够避免设置多个摄像头占用大量电子设备内部空间的问题，并且有利于控制电子设备的成本。
在一个实施例中，摄像头模组1还包括卡扣结构，卡扣结构处于扣合状态时，弹性件16处于压缩状态。卡扣结构处于分离状态时，弹性件16处于伸展状态。
在该具体的例子中，可以设置卡扣结构以配合弹性件16，例如可以将卡扣结构与弹性件16连接。具体可选地，卡扣结构包括可以相互扣合的第一卡扣和第二卡扣，第一卡扣与弹性件16的第一部分连接，第二卡扣与弹性件16的第二部分连接，当把第一卡扣和第二卡扣扣合在一起后，弹性件16的第一部分与第二部分之间的距离减小，即弹性件16处于压缩状态。当把第一卡扣和第二卡扣分离开后，弹性件16的第一部分与第二部分之间的距离增大，即弹性件16处于伸展状态。卡扣结构的设置使得弹性件16在压缩状态与伸展状态之间切换时更加容易操作，并且使得弹性件16在压缩状态下更加稳定。
参考图2所示，在一个实施例中，第一驱动机构15包括第一马达151、第一螺杆152和第一螺母153，第一螺母153套设在第一螺杆152上，第一螺杆152与第一马达151连接，第一螺母153与摄像头模组1连接，第一马达151转动时通过第一螺母153带动摄像头模组1从开口伸出或者缩回。
在该具体的例子中，例如，当电子设备的应用程序接收到启动摄像头模组1进行拍照的信号时，电子设备向第一马达151发送命令，第一马达151的输出轴旋转并带动第一螺杆152在第一螺母153内旋转，第一螺杆152与第一螺母153之间由于螺纹连接的作用，将旋转运动转换为第一螺母153沿第一螺杆152的平移运动，第一螺母153进而带动摄像头模组1做平移运动，在该实施例中，第一螺杆152的轴向即为第一方向。进一步地，可以在摄像头模组1与第一螺母153之间设置一个连接杆154，通过连接杆154将摄像头模组1与第一螺母153进行连接。此外，第一驱动机构15并不限于上述的结构，第一驱动机构15例如还可以是马达与齿轮齿 条组成的驱动机构，或者是马达与凸轮机构组成的驱动机构。第一驱动机构15例如还可以是电动缸、液压缸或气缸，或者其它能够提供平移运动的动力源的机构。
参考图3-图6所示，在一个实施例中，第二驱动机构18包括第二马达181、第二螺杆182和第二螺母183，第二螺母183套设在第二螺杆182上，第二螺杆182与第二马达181连接，第二螺母183与镜头组件11连接，第二马达181转动时通过第二螺母183带动镜头组件11靠近或者远离图像传感器。
在该具体的例子中，例如，当电子设备的应用程序接收到启动摄像头模组1进行拍照的信号并且需要对摄像头模组1进行成像焦距调整时，电子设备向第二马达181发送命令，第二马达181的输出轴旋转并带动第二螺杆182在第二螺母183内旋转，第二螺杆182与第二螺母183之间由于螺纹连接的作用，将旋转运动转换为第二螺母183沿第二螺杆182的平移运动，第二螺母183进而带动摄像头模组1在第二方向做平移运动以对镜头组件11的成像焦距进行调整。在该实施例中，第二螺杆182的轴向即为第二方向。此外，第二驱动机构18并不限于上述的结构，第二驱动机构18例如还可以是马达与齿轮齿条组成的驱动机构，或者是马达与凸轮机构组成的驱动机构。第二驱动机构18例如还可以是电动缸、液压缸、气缸或者其它能够提供平移运动的动力源的机构。
参考图3-图6所示，在一个实施例中，进一步地，镜头组件11至少包括第一透镜和第二透镜，第一透镜与第二螺母183连接，第二螺母183带动第一透镜靠近或者远离第二透镜。
在该具体的例子中，设置多个透镜组成镜头组件11，并且多个透镜之间可以发生相对移动，以实现该摄像头模组1的高倍光学变焦调节。由于在摄像头模组1从壳体2的开口伸出后，镜头组件11与图像传感器之间的距离得以增大，因此可以为更高倍数的光学变焦调节提供实现所需的物理 基础，可实现微距、长焦、多倍光学变焦等效果，为更高质量的拍照提供了条件。
参考图3-图6所示，在一个实施例中，进一步地，摄像头组件还包括音圈马达，音圈马达环绕第二透镜，音圈马达用于调整第二透镜与图像传感器之间的距离。
可选地，音圈马达具体可以包括定子171及动子172。进一步地，可以设置磁体作为定子171，例如将磁轭环和永磁铁作为定子171，同时设置线圈作为动子172。当然，也可以设置线圈作为定子171，同时设置磁体作为动子172。
在如下的一个具体的例子中，以磁体作为定子171、线圈作为动子172，并且设置三个透镜(第一透镜111a、第二透镜111b及第三透镜111c)为例进行详细说明：
参照图5、图6所示，对应于三个透镜设置有两套第二驱动机构18，其中两个第二马达181均与第三透镜111c连接，具体可以是连接在第三透镜111c的底部，然后左边的第二螺母183与第二透镜111b连接，右边的第二螺母183与第一透镜111a连接。磁体作为定子171固定设置，线圈作为动子172套接在第三透镜111c的外部。首先，参考图5所示，在摄像头模组1从壳体2的开口伸出后，镜头组件11与图像传感器之间的距离增大距离L，在调整成像焦距时，给线圈通入电流，磁体用于产生磁场，线圈与磁体相互作用，以产生洛伦兹力，线圈作为动子在洛伦兹力的作用下带动其上固定连接的镜头组件11沿第二方向进行平移运动，即实现了对成像焦距的调整，在这一调焦对焦过程中，由于之前镜头组件11与图像传感器之间的距离得以增大，因此增大了动子172连同镜头组件11整体的可移动行程，由此可以实现通过增大给线圈通入的电流，或者增强磁体的磁性强度或者增加线圈绕线的匝数，来得到更大的调焦对焦范围。
参考图6所示，当需要进行高倍光学变焦调节时，首先使摄像头模组1从壳体2的开口伸出，此时由于镜头组件11与图像传感器之间的距离增大距离L，这就为三个透镜之间的相对移动提供了更大的移动距离，即为实现高倍变焦提供了物理实现基础。例如，当电子设备的应用程序接收到启动摄像头模组1进行拍照的信号时，电子设备向左侧的第二马达181发送命令，左侧的第二马达181的输出轴旋转并带动左侧的第二螺杆182在左侧的第二螺母183内旋转，第二螺杆182与第二螺母183之间由于螺纹连接的作用，将旋转运动转换为左侧的第二螺母183沿左侧的第二螺杆182的平移运动，左侧的第二螺母183进而带动第二透镜111b沿第二方向做平移运动。同理，当电子设备向右侧的第二马达181发送命令时，右侧的第二螺母183也可以带动第一透镜111a沿第二方向做平移运动，在该实施例中，左右两侧的第二螺杆182的轴向即为第二方向，由此便实现了三个透镜之间的相对移动，从而实现了高倍光学变焦的调节。按照相同的原理，还可以实现四个、五个、六个甚至更多个透镜之间的相对移动。进一步具体地，每个透镜均包括保护框，镜片镶嵌设置在保护框中构成一个完整的透镜，线圈、第二马达181、第二螺母183均与对应的透镜的保护框连接。
在一个实施例中，摄像头模组1包括保护壳13和底座12，图像传感器设置在底座12上，保护壳13与底座12形成第二腔体14，镜头组件11设置于第二腔体14内且与图像传感器正对设置，保护壳13与镜头组件11相对的一侧设置有开口，开口上设置有保护镜片，保护壳13随着弹性件16伸缩。
在该具体的例子中，当摄像头模组1从壳体2的开口伸出后，具体是由弹性件16带动保护壳13相对底座12沿第二方向移动，当保护壳13沿第二方向远离底座12移动后，第二腔体14在第二方向的尺寸得以增大，由此增大了镜头组件11的可移动距离。进一步具体地，图像传感器包括 电路板191、感光元件192以及红外滤光片193。包含电路板191、感光元件192以及红外滤光片193的图像传感器固定设置在第二腔体14内。
在一个实施例中，电子设备包括中框，摄像头模组1位于第一腔体21内时，保护镜片与中框抵接。
当第一驱动机构15驱动摄像头模组1从壳体2外部经由壳体2上设置的开口移动回壳体2内时，弹性件16从伸展状态切换到压缩状态，保护镜片与电子设备的中框相抵接，以使弹性件16保持压缩的状态，从而维持整个摄像头模组1的稳定性。
在一个实施例中，进一步地，中框上与保护镜片抵接的位置设置有柔性保护件。
由于壳体2内设置的中框一般为比较坚硬的材质，因此为了防止保护镜片在反复的伸出缩回过程中被刮花，在中框面向保护镜片的一面设置柔性保护件，柔性保护件抵接在保护镜片上对保护镜片进行有效的保护，防止保护镜片发生损伤。可选地，柔性保护件例如可以是泡棉。
参考图3、图7所示，在一个实施例中，进一步地，弹性件16为弹簧，弹簧一端与底座12连接，另一端与保护壳13连接。选择弹簧作为弹性件16连接底座12与保护壳13，不仅价格较低、节省成本，并且弹簧的安装比较方便、容易操作。当摄像头模组1位于壳体2内时，中框抵接在保护壳13上使得弹簧保持压缩状态。当摄像头模组1伸出到壳体2外后，由于解除了中框对保护壳13的压力，因此，弹簧处于伸展状态，设计时可以让弹簧不要完全伸展，而是保留一定的压缩量，这样弹簧可以对保护壳13施加一个反作用力，保证保护壳13不会发生晃动。进一步可选地，如上所示，可以设置卡扣结构，具体可选地，卡扣结构包括可以相互扣合的第一卡扣和第二卡扣，第一卡扣与底座12连接，第二卡扣与保护壳13连接。当弹簧处于压缩状态时，第一卡扣和第二卡扣相互卡接以保证弹簧在压缩状态下更加稳定。
可选地，本申请实施例提供的电子设备例如可以是手机、笔记本电脑、平板电脑等。
