技术领域
本申请属于电子产品技术领域，具体涉及一种摄像模组及电子设备。
背景技术
拍摄功能逐渐成为如手机、平板等电子产品必不可少的功能，而拍摄效果的好坏也已逐渐成为判断终端电子设备是否高级的重要标准之一。消费者使用电子产品进行拍摄的场景越来越复杂化，当电子设备处于运动状态下，无疑使得拍照、摄像变得十分困难。就算是处于静止状态下，人体也会一直存在无法避免的生理震颤，这同样会直接导致拍摄图像质量下降，如图像模糊、不清晰。
现有技术中，在通过图像传感器芯片移动式所提供的光学防抖结构解决拍摄抖动问题时，市场上成熟的芯片防抖装置中，移动支架一般通过悬丝和弹簧等结构与金属壳连接。但是，移动支架与金属壳通过悬丝连接时，存在较大的可靠性风险；移动支架与金属壳通过弹簧连接时，x轴、y轴同时防抖易互相影响，防抖性能较差。且悬丝、弹簧连接方式存在生产工艺复杂，可靠性风险大、成本较高，且难以小型化的问题。
发明内容
本申请实施例的目的是提供一种摄像模组及电子设备，能够解决现有芯片防抖装置存在的可靠性风险大、防抖动效果较差的问题。
为了解决上述技术问题，本申请是这样实现的：
第一方面，本申请实施例提供了一种摄像模组，包括：
壳体，所述壳体上设置有第一线圈和第二线圈；
第一移动支架，所述第一移动支架上设置有与所述第一线圈对应的第一磁性元件；
第二移动支架，可用于固定图像传感器芯片，且所述第二移动支架上设置有与所述第二线圈对应的第二磁性元件；
其中，所述壳体、所述第一移动支架和所述第二移动支架依次层叠设置；所述第一移动支架和所述第二移动支架通过第一导向结构，可相对于所述壳体沿第一方向移动；所述第二移动支架通过第二导向结构，可相对于所述壳体和所述第一移动支架沿第二方向移动。
第二方面，本申请实施例提供了一种电子设备，所述电子设备包括如第一方面所述的摄像模组。
在本申请实施例中，摄像模组包括依次层叠设置的壳体、第一移动支架和第二移动支架；其中，在壳体上设置有第一线圈和第二线圈，在第一移动支架上设置有与第一线圈对应的第一磁性元件；第二移动支架可用于固定图像传感器芯片，且在其上设置有与第二线圈对应的第二磁性元件。在第一线圈通电的情况下，通过第一线圈和第一磁性元件驱动第一移动支架，第一移动支架和第二移动支架通过第一导向结构，可相对于壳体沿第一方向移动；在第二线圈通电的情况下，通过第二线圈和第二磁性元件驱动第二移动支架，第二移动支架通过第二导向结构，可相对于壳体和第一移动支架沿第二方向移动。如此，即可使图像处理芯片实现第一方向和第二方向上的独立位置补偿，丰富了抖动补偿的运动模式，提高了防抖效果，且结构的生产工艺简单，成本低，便于小型化。

如图3和4中，在一实施例中，摄像模组还包括：
红外滤光片(IR片)34，红外滤光片34设置在第二移动支架3上，且红外滤光片34与图像传感器芯片7正对。
在一实施例中，本申请实施例还提供一种电子设备，所述电子设备包括如上所述的摄像模组。
通过该摄像模组能够使图像处理芯片实现第一方向和第二方向上的独立位置补偿，能够提高电子设备的拍照稳定性和照片的拍摄成功率与质量。
其中，电子设备包括但不限于手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant， PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)等。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。此外，需要指出的是，本申请实施方式中的方法和装置的范围不限按示出或讨论的顺序来执行功能，还可包括根据所涉及的功能按基本同时的方式或按相反的顺序来执行功能，例如，可以按不同于所描述的次序来执行所描述的方法，并且还可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁碟、光盘)中，包括若干指令用以使得一台终端(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本申请各个实施例所述的方法。
上面结合附图对本申请的实施例进行了描述，但是本申请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申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
