技术领域
本申请实施例涉及通讯技术领域，尤其涉及一种相机组件及移动终端。
背景技术
手机、平板电脑等移动终端，目前已变成了人们日常生活中不可或缺的一部分。相机是移动终端中不可或缺的元器件，而消费者对相机的要求也越来越高，例如更高的像素、更大的广角等。现有的移动终端的相机的像素、广角等都已经发展到了一个全新的高度。除像素、广角等因素之外，在拍照过程中，相机发生的轻微抖动也会严重影响成像质量。
现有的相机的防抖方式主要为光学防抖，即通过光学元器件的设置，例如镜头设置，来避免或者减少捕捉光学信号过程中出现的仪器抖动现象，从而提高成像质量。但由于光学防抖需要移动光学镜头来实现，导致光学防抖系统成本居高不下，同时光学结构非常精密，组装的要求极高。

本申请实施例提供一种相机组件，其包括相机模组、第一无线传输模块及第一磁体，所述相机模组配置为获取图像，所述第一无线传输模块与 所述相机模组电性连接配置为数据传输。
进一步的，所述相机组件包括无线供电接收模块或电池，配置为为所述相机模组供电。
本申请实施例还提供一种移动终端，所述移动终端包括主体及如前所述的相机组件，所述主体包括壳体、第二无线传输模块及磁悬浮组件，所述第二无线传输模块配置为与第一无线传输模块建立通信连接以实现所述主体和所述相机组件的数据传输，所述磁悬浮组件配置为产生作用于所述第一磁体的磁力，使所述相机组件保持悬浮状态。
一种实现方式中，所述壳体包括收容部，所述移动终端包括安装于壳体的第二磁体，所述第二磁体配置为对第一磁体产生的磁力使所述相机组件保持于所述收容部。
一种实现方式中，所述相机模组包括至少两个镜头，所述相机组件位于所述收容部时，两个所述镜头沿竖直方向排列；所述相机组件处于悬浮状态时，两个所述镜头沿水平方向排列。
一种实现方式中，所述相机组件包括无线供电接收模块，所述主体包括设于壳体的无线供电发射模块，所述无线供电接收模块接收所述无线供电发射模块的电能，为所述相机模组供电。
一种实现方式中，所述磁悬浮组件设于所述壳体的任一侧，所述磁悬浮组件配置为产生作用于第一磁体的磁力，使所述相机组件悬浮于所述壳体的上方。
一种实现方式中，所述磁悬浮组件包括至少一个电磁线圈，电磁线圈通电后对第一磁体产生磁力，使所述相机组件保持悬浮状态。
一种实现方式中，所述磁悬浮组件包括多个电磁线圈，多个所述电磁线圈沿周向排列。
一种实现方式中，所述主体包括处理单元、电源管理单元及位置传感 器，所述处理单元与位置传感器及电源管理单元分别电性连接，所述电源管理单元为所述电磁线圈供电，所述位置传感器配置为获取相机组件相对主体的位置，所述处理器根据相机组件相对主体的位置，通过电源管理单元控制电磁线圈的通电电流。
一种实现方式中，所述位置传感器包括陀螺仪、重力传感器、加速度传感器中至少一种。

本申请实施例提供一种相机组件，用于移动终端，移动终端例如为手 机、平板电脑、智能穿戴设备等。相机组件包括相机模组、第一无线传输模块及第一磁体，所述第一无线传输模块与所述相机模组电性连接且配置为数据传输。本申请实施例中，由于相机组件中设有第一磁体，可通过第一磁体受到的磁力使相机组件处于悬浮状态，即使移动终端的主体发生轻微抖动或晃动，但第一磁体仍处于等强磁场中而所受磁力未发生变化，因此相机组件仍能保持静止，从而保证良好的成像质量，此外，相机组件保持悬浮状态也能带来全新的用户体验。本申请实施例中，“磁体”包括永磁体和电磁体，“磁力”包括永磁体产生的磁力，也包括电磁体产生的电磁力。
请结合图1及图2，本实施例的相机组件1包括相机模组11、连接于相机模组11的第一无线传输模块13、第一磁体14及无线供电接收模块15，这里的“连接”可以是直接连接，也可以是通过连接元件间接连接，也可以是嵌在其容纳空间内。所述无线供电接收模块15分别与相机模组11及第一无线传输模块13电性连接，所述第一磁体14位于第一无线传输模块13及无线供电接收模块15之间。所述无线供电接收模块15配置为接收电能，并为所述相机模组11及所述第一无线传输模块13供电，所述相机模组11配置为获取图像。所述第一无线传输模块13配置为和移动终端配对连接并进行数据传输，向移动终端传输拍摄的图像以及接收移动终端发出的各种控制信号。
所述相机模组11包括镜头12、光学镜片、成像元件、电路板、马达等结构，第一无线传输模块13与相机模组11的电路板电性连接。本实施例中镜头12的数量为两个，两个镜头12分别为变焦镜头和长焦镜头，在其他实施例中，相机模组11的数量还可为一个或两个以上。
所述第一无线传输模块13例如为近距离毫米波无线传输模块、NFC(Near Field Communication，近场通讯)模块、蓝牙模块、ZigBee模块、WiFi模块等，通过无线方式进行数据传输。在其他实施例中，第一无线传 输模块13也可以无需无线供电接收模块15供电，例如第一无线传输模块13为NFC模块，通过射频信号感应电压来供电。
所述第一无线传输模块13例如为线圈，可接收移动终端的电能，即利用电磁场来传输电能，原理上类似于变压器。在其他实施例中，也可以用电池替换无线供电接收模块15，直接为相机模组11及第一无线传输模块13供电。
可以理解的是，为避免第一磁体14和第一无线传输模块13之间的电磁场相互影响，可在两者之间设置金属屏蔽元件。
由于相机组件1的数据传输、供电均不依赖于其他部件，因而可借助第一磁体14受到的等强磁场的磁力使相机组件1保持悬浮状态，在拍照时即使移动终端的主体发生小幅度的抖动或晃动，第一磁体14仍处于等强磁场中，第一磁体14受到的磁力未发生变化，相机组件1仍能保持静止状态，从而保证相机模组11的成像质量。
另一方面，本申请实施例还提供一种移动终端，其包括主体及前述任一实施例的相机组件。请结合图3至图4，本实施例中，移动终端例如为手机，其包括主体2及相机组件1。所述主体2包括壳体21、安装于壳体21的第二无线传输模块22及磁悬浮组件23及无线供电发射模块24，所述磁悬浮组件23位于第二无线传输模块22及无线供电发射模块24之间。所述第二无线传输模块22配置为与第一无线传输模块13建立通信连接以实现所述主体2和所述相机组件1的数据传输，所述磁悬浮组件23配置为产生作用于第一磁体14的磁力，使所述相机组件1保持悬浮状态，所述无线供电发射模块24配置为向无线供电接收模块15传输电能。
当然，移动终端还包括显示屏25、处理单元26、电源管理单元29、存储单元、电池等元件，其中壳体21为移动终端的外壳。所述第二无线传输模块22的传输协议与第一无线传输模块13的传输协议一致，例如为近距 离数据传输模块、NFC模块、蓝牙模块、ZigBee模块、WiFi模块。所述无线供电发射模块24为线圈。
所述磁悬浮组件23包括至少一个电磁线圈，电磁线圈通电后对磁体产生磁力，配置为在预定区域内提供等强磁场，在该预定区域内，磁场强度及磁场方向相同或近似于相同，等强磁场作用于第一磁体14的磁力使所述相机组件1保持悬浮状态。
请结合图5，所述磁悬浮组件23包括多个电磁线圈231，多个所述电磁线圈231沿周向排列，本实施例中电磁线圈231的数量为四个，所述相机组件1处于悬浮状态时，第一磁体14与磁悬浮组件23的中心对齐。所述电磁线圈231通电后产生磁力，此时的磁力为排斥力，磁力的水平分力使相机组件1在水平方向上受力为零而保持静止，磁力的竖直分力用于抵消重力，使相机组件1在竖直方向上受力为零而保持静止。在其他实施例中，磁悬浮组件23可以由多个永磁体组成，或者由永磁体和电磁体共同组成，同样能够使相机组件1所受合力为零而保持静止。
当用户在使用移动终端进行拍照时，可能会不慎轻微抖动移动终端的主体2，但主体2的轻微抖动导致磁悬浮组件23产生的位移量几乎可以忽略不计，基本等强磁场几乎没有变化，即第一磁体14仍处于等强磁场中，第一磁体14受到的磁力未发生变化，磁悬浮组件23提供的磁力仍能使相机组件1处于悬浮状态而保持静止。
请结合图5及图6，优选的，所述主体2还包括与处理单元26电性连接的位置传感器27，电池通过电源管理单元29为各个电磁线圈231供电。所述位置传感器27配置为获取相机组件1相对于主体2的位置，处理单元26根据相机组件1的相对主体2的位置，通过电源管理单元29调整各个电磁线圈231的通电电流，从而调节第一磁体14所受到的磁力，使相机组件1所受的合力为零而始终保持静止，即使主体2发生较大幅度的抖动或晃动， 使第一磁体14脱离上述等强磁场，调整后的磁力仍能使相机组件1保持静止状态。
本实施例中，所述位置传感器27包括陀螺仪、重力传感器、加速度传感器中至少一种。现有的移动终端通常配有陀螺仪、重力传感器、加速度传感器等传感器，因而不会增加元件成本和装配成本。
请结合图8，当所述相机组件1处于悬浮状态时，所述位置传感器27，例如陀螺仪，检测所述主体2与所述相机组件1所成的夹角α，夹角α为所述主体2的中心线(或近似中心线)与所述相机组件1的中心线(或近似中心线)所成的角度，这里的中心线可以是竖直的中心线，也可是水平的中心线。当所述夹角α大于预设的阈值时，所述处理单元26通过电源管理单元29控制电磁线圈231的通电电流，改变所述电磁圈231作用于所述第一磁体14的磁力的大小和/或方向等参数。预设的阈值可通过实验测得，即当所述夹角α不大于预设的阈值时，相机组件1可稳定地悬浮于主体2的上方。
譬如，当主体2的上端向用户倾斜时，所述主体2与所述相机组件1所成的夹角α大于预设阈值，靠近用户侧的电磁线圈231与第一磁体14的距离减小，对第一磁体14产生的磁力相应增大，处理单元26通过电源管理单元29减小靠近用户侧的电磁线圈231的通电电流或增大远离用户侧的电磁线圈231的通电电流，从而改变所述电磁线圈231作用于所述第一磁体14的磁力，使相机组件1的受力为零而保持静止，即仍处于悬浮状态。
在一个实施例中，当所述相机组件1处于悬浮状态时，所述位置传感器27检测所述主体2与所述相机组件1所成的夹角α，当所述夹角α大于预设的阈值时，所述处理单元26通过电源管理单元29改变电磁线圈231的通电电流的方向，使所述电磁线圈231对所述第一磁体14施加吸引力，相机组件1也对应转动α并被吸附于主体2的上端，从而避免相机组件1 摔落而损坏。需要注意的是，用户可能因拍摄角度需要而主动调整主体2的角度，相机组件1转动至与主体2一致的角度，可满足用户对拍摄角度变化的要求。
本实施例中，所述磁悬浮组件23设于所述壳体21的上侧，所述磁悬浮组件23配置为产生作用于第一磁体14的磁力，使所述相机组件1悬浮于所述壳体21的上侧。在其他实施例中，根据不同需的求，所述磁悬浮组件23设于所述壳体21的任一侧，例如设于任一侧壁或设于任一侧壁内部，侧壁包括壳体21的上、下、左、右四个壁。无论用户如何握持主体2，均可使相机组件1悬浮于主体2的上方。
请结合图3、图4及图7，所述壳体21包括配置为容纳所述相机组件1的收容部211，所述主体2还包括安装于壳体21的第二磁体28，所述第二磁体28设于收容部211内或邻近收容部211，所述第二磁体28配置为对第一磁体14产生磁力，使所述相机组件1保持于所述收容部211内，即相机组件1和移动终端的主体2可拆卸连接，当容纳于收容部211时，通过磁吸力进行固定。相机组件1在不使用时可容纳于收容部211。当然，相机组件1容纳于收容部211时也可以用来拍照或摄像，由于第一无线传输模块13及第二无线传输模块22之间距离仍然很小，两者仍能进行数据传输，而收容部211内设置有另一无线供电发射模块24，配置为向无线供电接收模块15传输电能，以为相机模组11供电。
需要注意是，当相机组件1处于悬浮状态时，两个镜头12沿水平方向排列；当所述相机组件1位于所述收容部211内时，两个镜头12沿竖直方向排列。用户可根据需求选择镜头12的排布方式，即横向排列或纵向排列，不转动主体2即可满足用户横拍或竖拍的需求。
请结合图3及图9，图3所示的相机模组11的镜头12朝向主体2的后方。用户可将相机组件1相对其竖直的中心线旋转180度，而使所述相机 模组11的镜头12朝向主体2的前方，即面向用户，从而允许由于进行自拍或视频聊天。换言之，本申请实施例的移动终端不需要另外设置前置摄像头，从而降低了前置摄像头的元件成本和装配成本，而且由于不设置前置摄像头，有利于提高移动终端的屏占比，获得更好的用户体验。此外，相机模组11的规格与现有移动终端的后置摄像头的规格相当，因此成像质量也会明显优于现有的前置摄像头的成像质量。
以上所述仅为本申请实施例的较佳实施例而已，并不用以限制本申请实施例，凡在本申请实施例的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本申请实施例保护的范围之内。
工业实用性
本申请实施例中，由于相机组件中设有第一磁体，通过第一磁体受到的磁力使相机组件处于悬浮状态，即使移动终端的主体发生轻微抖动或晃动，但第一磁体仍处于等强磁场中，所受磁力未发生变化，因此相机组件仍能保持静止，从而保证良好的成像质量，此外，相机组件保持悬浮状态也能带来全新的用户体验。
