为了使本技术领域的人员更好地理解本公开中的技术方案，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，所描述的实施例仅仅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，都应当属于本公开保护的范围。
本公开实施例提供了一种双摄像设备和移动终端，解决双摄像头中两个防抖马达间的磁场相互干扰，导致防抖失败的问题。该双摄像头设备可以应用于移动终端内，本公开实施例提及的移动终端包括但不限于手机、平板电脑、电脑、可穿戴设备等智能终端。
本公开一实施例提供的双摄像设备可以包含如下结构：第一摄像头和第二摄像头。第一摄像头包括第一马达，第一马达内部设置有第一磁铁和第一线圈，该第一线圈用于在通电时驱动第一磁铁移动。第二摄像头包括第二马达，该第二马达内部设置有第二磁铁和第二线圈，该第二线圈用于在通电时驱动第二磁铁移动。
第一马达和第二马达并列或并排设置，且第一磁铁设置于第一马达的第一端，第二磁铁设置于第二马达的第二端，上述第一端和上述第二端为第一马达和第二马达中相距最远的两端。
本公开实施例中，第一马达中第一线圈在通电时驱动第一磁铁的移动，第二马达中的第二线圈在通电时驱动第二磁铁的移动，上述两种移动能够实现双摄像头的防抖功能。并且，第一磁铁设置于第一马达的第一端，第二磁铁设置于第二马达的第二端，第一端和第二端为第一马达和第二马达中相距最远的两端，通过增加第一磁铁和第二磁铁之间的距离，能够缓解双摄像头中两个防抖马达间的磁场相互干扰的问题，保证摄像头的防抖效果。
本公开一实施例中，第一马达的形状可以为正方形、长方形、六边形等，还可以为圆形、椭圆形等其他形状。第二马达的形状可以为正方形、长方形、六边形等，还可以为圆形、椭圆形等其他形状。且第一马达的形状和第二马达的形状可以相同也可以不同。
本实施例中，第一磁铁设置于第一马达的第一端，第二磁铁设置于第二马达的第二端，上述第一端和上述第二端为第一马达和第二马达中相距最远 的两端，比如，当第一马达和第二马达均为矩形结构时，第一马达和第二马达紧靠放置时形成一个长方体，该相距最远的两端可以为该长方体的对角线的两端。
本公开一实施例中，第一马达和第二马达均为矩形结构。第一磁铁的数量为两个，一个第一磁铁位于第一马达的矩形结构的第一拐角处，另一第一磁铁位于第一马达的矩形结构的第二拐角处，第二磁铁的数量为两个，一个第二磁铁位于第二马达的矩形结构的第三拐角处，另一个第二磁铁位于第二马达的矩形结构的第四拐角处。
图1为本公开一实施例提供的双摄像头的结构示意图。如图1所示，该双摄像头包括：第一马达100，第二马达200，其中，第一马达100为矩形结构，第二马达200为矩形结构。第一马达100内部设置有第一磁铁101，第二马达200内部设置有第二磁铁201。第一磁铁101的数量为两个，分别位于第一马达100的第一拐角处和第二拐角处，第二磁铁201的数量为两个，分别位于第二马达200的第三拐角处和第四拐角处。
如图1所示，通过将第一磁铁101和第二磁铁201设置于第一马达100和第二马达200的拐角处，并且保证第一磁铁101和第二磁铁201设置于第一马达100和第二马达200的对角线的两端，能够使得第一磁铁101和第二磁铁201之间的距离最远，从而增加第一磁铁101和第二磁铁201之间的距离，缓解双摄像头中两个防抖马达间的磁场相互干扰的问题，保证摄像头的防抖效果。
如图1所示，本实施例中，通过将第一磁铁101和第二磁铁201设置第一马达100和第二马达200的对角线的两端，与相关技术中在矩形马达的四边分别设置磁铁的方式相比，无需在矩形马达相邻的两边设置磁铁，从而减小马达间的间距，减小摄像头的体积。
当第一马达100和第二马达200均为矩形结构时，如图1所示，第一磁铁101和第二磁铁201可以倾斜设置在第一马达100和第二马达200中，当然，第一磁铁101和第二磁铁201也可以均沿水平方向设置，或者均沿竖直方向设置，这里不做限定。
如图1所示，在第一马达100中，第一拐角处的第一磁铁101与第一马 达100的第一边缘A和第二边缘B相邻，第二拐角处的第一磁铁101与第一马达100的第一边缘A和第三边缘C相邻，并且，第一拐角处的第一磁铁101相对于第一边缘A的倾斜角度，等于，第二拐角处的第一磁铁101相对于第一边缘A的倾斜角度；
第二马达200中，第三拐角处的第二磁铁201与第二马达200的第四边缘D和第五边缘E相邻，第四拐角处的第二磁铁201与第二马达200的第四边缘D和第六边缘F相邻，并且，第三拐角处的第二磁铁201相对于第四边缘D的倾斜角度，等于，所述第四拐角处的所述第二磁铁相对于所述第四边缘的倾斜角度。
比如，位于图1上方的第一磁铁101与第一边缘的夹角为45度，位于图1下方的第一磁铁101与第一边缘的夹角为45度，位于图1上方的第二磁铁201与第四边缘的夹角为45度，位于图1下方的第二磁铁201与第四边缘的夹角为45度。
本实施例中，第一磁铁101的倾斜角度和第二磁铁201的倾斜角度可以相同，可以不同，这里不做限定。
进一步地，当第一马达100和第二马达200均为矩形结构时，为使得第一磁铁101的形状与第一马达100的形状相适配，便于第一磁铁101的安装，如图1所示，第一磁铁101的形状可以为梯形，即，第一磁铁101为梯形体磁铁，第一线圈102的形状可以为梯形，同理，第二磁铁201的形状为梯形，即，第二磁铁201为梯形体磁铁，第二线圈202的形状可以为梯形。
通过设置第一磁铁101和第二磁铁201的形状为梯形，能够方便第一磁铁101和第二磁铁201在矩形马达中的安装。
通过设置第一线圈102的形状和第一磁铁101的形状相同，第二线圈202的形状和第二磁铁201的形状相同，能够便于第一磁铁101和第一线圈102的安装，以及第二磁铁201和第二线圈202的安装，并且保证第一线圈102通电后产生的电磁力更准确的驱动第一磁铁101移动，第二线圈202通电后产生的电磁力更准确的驱动第二磁铁201移动。
当然，本公开实施例中，第一线圈102和第二线圈202的形状不限于梯形，也可以是长方形、正方形或者U形等其他形状。
进一步地，本实施例中，第一马达100内部还设置有第一霍尔元件，第一线圈102位于第一磁铁101和第一霍尔元件之间，第二马达200内部还设置有第二霍尔元件，第二线圈202位于第二磁铁201和第一霍尔元件之间。
第一霍尔元件能够在第一磁铁101移动过程中，感测磁场的变化情况，实现闭环反馈，同理，第二霍尔元件能够在第二磁铁201移动过程中，感测磁场的变化情况，实现闭环反馈。
图2为本公开一实施例提供的第一马达的剖面示意图，如图2所示，沿朝向移动终端内部的方向，第一磁铁101下方设置有第一线圈102，第一线圈102下方设置有第一霍尔元件103。

本公开实施例中，第一马达100中，第一磁铁101位于第一磁铁座中，第一磁铁座通过第一悬线与第一马达100的硬件壳体相连接。第二马达中200中，第二磁铁201位于第二磁铁座中，第二磁铁座通过第二悬线与第二马达200的硬件壳体相连接。
一个实施例中，第一马达100中的第一磁铁101均为梯形，第一磁铁座为矩形，第一悬线包含四个悬线，分别装在第一磁铁座的四角，用于支撑第一磁铁座，从而通过第一磁铁座带动第一磁铁移动；第二马达200中的第二磁铁201均为梯形，第二磁铁座为矩形，第二悬线包含四个悬线，分别装在第二磁铁座的四角，用于支撑第二磁铁座，从而通过第二磁铁座带动第二磁铁移动。第一磁铁座和第二磁铁座的形状不做限定，第一悬线和第二悬线的数量不做限定。
本公开实施例中，由于第一霍尔元件103位于第一磁铁101的第一侧面处，第二霍尔元件203位于第二磁铁201的第二侧面处，且第一磁铁101和第二磁铁201设置于第一马达100和第二马达200的对角线两端，因此在保证第一磁铁101和第二磁铁201距离最远的情况下，能够增加第一马达100中的第一霍尔元件103和第二磁铁201之间的距离，增加第二马达200中的第二霍尔元件203和第一磁铁101之间的距离，从而减少两个马达之间的磁 干扰。
图4为本公开实施例中提供的第一磁铁和第二磁铁的受力示意图，基于图1所提供的结构，图4中，控制第一线圈102和第二线圈202固定不动，当给第一马达100中左上侧的第一线圈102通入第一预设方向的电流时，左上第一磁铁101产生的电磁力推动左上第一磁铁101向w+方向移动，当左上第一线圈102通入第二预设方向的电流，左上侧第一磁铁101向w-方向移动。当给第一马达100中左下侧的第一线圈102通入第一预设方向的电流时，左下侧第一磁铁101产生的电磁力推动左下侧第一磁铁101向v+方向移动，当左上侧第一线圈102通入第二预设方向的电流，左下侧第一磁铁101向v-方向移动。当第一马达100中的两个线圈均通电时，W+和V+方向合成X+方向运动，W-和V-方向合成X-方向运动；W-和V+方向合成y+方向运动，W+和V-方向合成Y-方向运动，从而实现防抖功能。第二马达200中第二磁铁201的受力方向与第一磁铁101类似，在此不再赘述。
进一步地，如图1所示，本实施例中，第一磁铁101的朝向第一马达100内部的侧面为N极，第一磁铁101的远离第一马达100内部的侧面为S极。第二磁铁201的朝向第二马达200内部的侧面为N极，第二磁铁201的远离第二马达200内部的侧面为S极。
为进一步减小第一马达100和第二马达200之间的磁干扰，第一马达100的外壳可以采用弱磁或无磁材料制作，第二马达200的外壳可以采用弱磁或无磁材料制作。
另外，本公开实施例还提供了一种移动终端，包括上面所述的双摄像头设备。
可见，该移动终端中，第一马达中第一线圈在通电时驱动第一磁铁的移动，第二马达中的第二线圈在通电时驱动第二磁铁的移动，上述两种移动能够实现双摄像头的防抖功能。并且，第一磁铁设置于第一马达的第一端，第二磁铁设置于第二马达的第二端，第一端和第二端为第一马达和第二马达中相距最远的两端，通过增加第一磁铁和第二磁铁之间的距离，能够缓解双摄像头中两个防抖马达间的磁场相互干扰的问题，保证摄像头的防抖效果。
