摄像头模组及电子设备
交叉引用
本发明要求在2020年02月28日提交中国专利局、申请号为202010133791.0、发明名称为“摄像头模组及电子设备”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本发明涉及通信技术领域，尤其涉及一种摄像头模组及电子设备。
背景技术
随着电子设备的快速发展，其应用得越来越广泛，诸如手机、平板电脑等电子设备在人们的工作、生活、娱乐等方面发挥着越来越多的作用。特别地，随着近几年互联网社交媒体的发达，用户在追求电子设备更为方便的操作系统的同时，也越来越关注电子设备的图像摄取功能的优劣。
现今很多人使用电子设备拍照或者拍视频，人们在拍照过程中难免会因为手部抖动或者支架震动等因素使得摄像头模组抖动，一旦发生抖动，则拍出来的照片或视频会模糊不清，影响用户体验。因此，如何解决摄像头模组在使用过程中的抖动问题，一直是摄像装置技术领域所面临的难题。而在解决这个问题的过程中，摄像头模组一般采用电子防抖或OIS防抖(Optical image stabilization，光学防抖)等技术。
但是，OIS防抖技术的结构较为复杂，并且其对于较大幅度的抖动补偿较差；电子防抖技术的缺陷主要是由于其通过提高感光度来进行防抖，因此，在高感光度的情况下，拍摄画面会产生噪点，因而降低了画面的画质。且电子防抖技术的算法复杂，在调整摄像头的过程中需要经过大量运算。可见，现有的防抖技术存在不能较好地解决摄像头模组抖动的问题。
发明内容
本发明公开一种摄像头模组及电子设备，以解决摄像头模组的防抖效果不佳的问题。
为解决上述技术问题，本发明是这样实现的：
第一方面，本发明实施例公开一种摄像头模组，包括支架、可转动模组、第一磁性件和第二磁性件；所述支架设有转动腔，所述可转动模组包括摄像头和转动体，所述摄像头与所述转动体固定连接，所述转动体可转动地设置于所述转动腔，且所述可转动模组的重心与所述可转动模组的几何中心之间的距离大于0；所述第一磁性件设置于所述支架，所述第二磁性件设置于所述转动体，所述第一磁性件和所述第二磁性件中，至少一个为电磁性件，且所述第一磁性件与所述第二磁性件相对设置；在所述电磁性件未通电的情况下，在重力的作用下所述摄像头可转动。
第二方面，本发明实施例公开一种电子设备，包括壳体和上述摄像头模组，所述壳体 开设有容纳槽，所述摄像头模组设置于所述容纳槽，所述容纳槽的底面与所述转动体限位配合。
本发明采用的技术方案能够达到以下有益效果：
在本发明实施例中，通过将摄像头设置在转动体上，以组成可转动模组，可转动模组为偏心结构，并且转动体能够相对支架的转动腔转动。当电子设备抖动时，偏心设置的可转动模组在重力的作用下，使得转动体相对转动腔转动，从而使得可转动模组能够基本保持与电子设备未抖动时的位置相同。在可转动模组基本保持原位的情况下，能够使得摄像头的朝向基本保持不变，从而使进入摄像头的光线保持稳定。同时，在电磁性件通电的情况下，第一磁性件与第二磁性件之间的磁力作用使得转动体更加精准地转动，从而能够对可转动模组的位置更加准确地调整，以使可转动模组能够更加稳定地保持原位，使得摄像头的朝向保持不变，从而使得摄像头模组的防抖效果较好。因此，本方案能够较好地解决摄像头模组的防抖效果不佳的问题。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
以下结合附图，详细说明本发明各个实施例公开的技术方案。
请参考图1至图4，本发明实施例公开一种摄像头模组，所公开的摄像头模组包括支架100和可转动模组200。
支架100为摄像头模组的基础构件，为摄像头模组的其他部件提供安装基础。支架 100设有转动腔110。
可转动模组200包括摄像头210和转动体220，摄像头210的种类有多种，例如模拟摄像头、数字摄像头等，本发明实施例不作限制。上述摄像头210的具体结构及工作原理为公知技术在此不再赘述。
摄像头210与转动体220固定连接，且可转动模组200的重心与可转动模组200的几何中心之间的距离大于0，以使可转动模组200为偏心结构。转动体220可转动地设置于转动腔110，以使转动体220可相对转动腔110转动，从而带动摄像头210转动。
在本发明实施例中，偏心设置的可转动模组200在重力的作用下转动，当转动体220与转动腔110之间的摩擦力较大或者过小时，使得可转动模组200不能或较难灵活地、稳定地转动，导致可转动模组200较难保持原位。基于此，摄像头模组还包括第一磁性件300和第二磁性件400。在第一磁性件300和第二磁性件400中，至少一个为电磁性件。第一磁性件300设置于支架100，第二磁性件400设置于转动体220，且第一磁性件300与第二磁性件400相对设置。
在电磁性件未通电的情况下，在重力的作用下摄像头210可转动，从而实现防抖的效果。在电磁性件通电的情况下，第一磁性件300与第二磁性件400之间形成磁力作用，该磁力作用使得支架100和转动体220可以相对转动，并且可以控制支架100和转动体220相对转动时的幅度、速度等参数。
具体地，第一磁性件300和第二磁性件400的种类可以有多种，例如第一磁性件300可以为电磁性件，第二磁性件400为永磁体，或者，第一磁性件300和第二磁性件400均为电磁性件。可选地，第一磁性件300为永磁体，第二磁性件400可以为电磁性件，电磁性件设置在转动体220上，摄像头210可以与电磁性件电连接，从而能够方便为电磁性件供电，简化电磁性件电连接的方式。与此同时，当第一磁性件300为电磁性件时，由于第一磁性件300设置于支架100，使得第一磁性件300的电连接方式较为复杂，而第一磁性件300为永磁体时，由于永磁体不需要进行电连接，同时永磁体的成本更低，因此既能够降低成本，又可以使得第一磁性件300方便设置。
在本发明实施例中，摄像头210设置在转动体220上，两者组成可转动模组200。可转动模组200为偏心结构，并且转动体220能够相对支架100的转动腔110转动。摄像头210处于抖动状态时，偏心设置的可转动模组200在重力的作用下，使得转动体220相对转动腔110转动，从而使得可转动模组200能够基本保持原位。在此情况下，能够使得摄像头210的朝向基本保持不变，从而使进入摄像头210的光线保持稳定。同时，在电磁性件通电的情况下，第一磁性件300与第二磁性件400之间的磁力作用使得转动体220更加精准地转动，从而能够对可转动模组200的位置更加准确地调整。可转动模组200能够在偏心设置以及磁力作用下更加稳定地保持原位，使得摄像头210的朝向保持不变，从而使得摄像头模组的防抖效果的生成时间更短，防抖效果较好。
进一步地，第一磁性件300和第二磁性件400的数量可以为多个，且第一磁性件300的数量和第二磁性件400的数量相等。多个第二磁性件400沿环绕摄像头210的光轴的方向间隔分布。具体地，多个第一磁性件300与多个第二磁性件400一一对应设置。多个第一磁性件300和多个第二磁性件400能够驱动转动体220绕多个转动轴方向转动，从而能够对摄像头模组进行更为全面、准确地调整。这样能够更好地解决摄像头模组在使用过程 中抖动的问题，使得摄像头模组的抖动不会或较难影响摄像头210的拍摄效果。
在本发明的一些实施例中，第二磁性件400的数量为三个，且任意两个第二磁性件400之间的连线分别为第一连线、第二连线和第三连线，第一连线、第二连线和第三连线围成等腰直角三角形，第二磁性件400在转动体220上呈规律分布，以使多个第一磁性件300和多个第二磁性件400能够较为均衡地驱动转动体220转动，从而能够较为平稳地调整可转动模组200，进而使得摄像头模组的稳定性较高。当摄像头模组的旋转腔为正球体形或正方体形的时候，三个第二磁性件将会被设置在同一竖直平面中；当摄像头模组的旋转腔为椭球体形或者其他形状的时候，三个第二磁性件将会被设置在同一平面中，但该平面与竖直平面之间可能具有夹角。
在本发明的另一些实施例中，在第二磁性件400的数量为三个的情况下，第一连线、第二连线和第三连线围成等边三角形，以使三个第二磁性件400均匀排布。当摄像头模组的旋转腔为正球体形或正方体形的时候，三个第二磁性件将会被设置在同一竖直平面中；当摄像头模组的旋转腔为椭球体形或者其他形状的时候，三个第二磁性件将会被设置在同一平面中，但该平面与竖直平面之间可能具有夹角。
当然，第二磁性件400的数量还可以为两个，此时，两个第二磁性件400与几何中心的连线形成的夹角可以为180°；第二磁性件400的数量也可以为四个，此时，四个第二磁性件400中，任意相邻的两个第二磁性件400与几何中心的连线可以相垂直。更多地，第二磁性件400的数量还可以为五个，此时，五个第二磁性件400中，任意相邻的两个第二磁性件400与几何中心的连线形成的夹角可以约等于72°。以此类推，第二磁性件400还可以设置有更多个，本发明实施例对此不做限制。
根据上文描述可知，在第二磁性件400的数量为三个的情况下，任意两个第二磁性件400之间的连线分别为第一连线、第二连线和第三连线，第一连线、第二连线和第三连线围成等腰直角三角形，多个第一磁性件300和多个第二磁性件400能够较为均衡地驱动转动体220转动，同时第二磁性件400的数量较少，使得第二磁性件400占用的空间更小，同时可以降低摄像头模组的成本。
当电磁性件上的磁力较为恒定时，第一磁性件300与第二磁性件400之间的距离会随着转动体220的转动而发生变化，当第一磁性件300与第二磁性件400之间的距离增大时，第一磁性件300与第二磁性件400之间力的作用会随着距离的增大而逐渐变小，导致转动体220的转动效果较差。因此，在一种可选的方案中，电磁性件可以包括多个子线圈，多个子线圈沿摄像头210的光轴方向依次排列设置，使得在第一磁性件300和第二磁性件400驱动转动体220运动的过程中，第一磁性件300与第二磁性件400之间的磁场能够基本保持稳定，以使第一磁性件300和第二磁性件400之间力的作用较为稳定，从而使得转动体220能够稳定地转动，以提高转动体220的转动效果，进而提高对摄像头210的调整效果。
进一步地，摄像头模组还可以包括多个控制器，多个控制器与多个子线圈对应电连接，以使各子线圈可被单独控制。此方案中，各子线圈被单独控制，使得电磁性件上的磁力可以根据可转动模组200转动情况具体调整，从而方便控制可转动模组200的转动，进而使得摄像头模组的防抖效果较好。具体地，可以控制子线圈的通电与否、电流大小等。例如，当子线圈的数量为五个的情况下，在电子设备所受到的抖动较小，第一磁性件与第二磁性 件仅需要对于可转动模组施加较小的调整作用力即可。因此电子设备可控制各子线圈的控制器，使五个线圈中三个子线圈用于控制摄像头的防抖操作，另外两个子线圈处于不工作状态。当然，本领域技术人员可以理解的是，另外两个子线圈还可以通以极小电流，使该子线圈对于第一磁性件的作用力低于其他三个子线圈对于第一磁性件的作用力。
在本发明实施例中，第二磁性件400设置于转动体220，为了不使第二磁性件400阻碍转动体220转动，可选地，转动体220可以设有第二凹部221，第二磁性件400设置于第二凹部221，且第二磁性件与第二凹部共面，从而能够防止因第二磁性件400凸起于转动体220的外表面而阻碍转动体220转动，进而使得转动体能够平稳流畅地转动。同时，第二磁性件400位于第二凹部221中，能够减小第二磁性件400和转动体220的占用空间，从而提高摄像头模组的空间利用率。
可选地，支架100可以设有第一凹部120，第一磁性件300设置于第一凹部120，且第一磁性件与第一凹部共面，这样可以使得支架100与第一磁性件300组成的整体结构的外观较为平整，同时，第一磁性件300位于第一凹部120中，能够使得第一磁性件300和支架100的占用空间较小，从而能够提高电子设备的空间利用率。
摄像头210设置于转动体220的方式有多种，例如粘接、卡接或螺纹连接，本发明实施例对此不做限制。在一种可选的方案中，转动体220可以设有容纳空间222，摄像头210至少部分位于容纳空间222中。此种情况下，摄像头模组在摄像头210的光轴方向上的尺寸较小，从而更有利于摄像头模组的小型化，进而能够减小电子设备的厚度，提高电子设备的用户体验感。
在一种可选的方案中，转动体220和转动腔110的形状可以均为球形，且相较于矩形的转动体和转动腔，球形的转动体220和转动腔110之间拥有更小的间隙，利于两者相对转动，并有利于调整可转动模组200的位置。
摄像头210需要与其他器件数据(例如电子设备的主板等)连接，以使摄像头210能够与其他器件进行数据传输。可选地，摄像头模组还可以包括条形电路板600，摄像头210与条形电路板600电连接，且条形电路板600在摄像头210的光轴方向上延伸，以使摄像头210能够通过条形电路板600与其他器件电连接，从而方便摄像头210与其他器件的数据传输。此种电连接方式简单可靠，且方便设置。
当然，摄像头210也可以通过其他方式与其他器件数据连接，另一种可选的实施例中，摄像头210可以设置有无线传输模块，摄像头210可以通过无线传输模块与其他器件数据传输。
基于本发明实施例公开的摄像头模组，本发明实施例还公开一种电子设备，所公开的电子设备包括上文任意实施例所述的摄像头模组，从而使得配置有上述摄像头模组的电子设备具有较优的拍摄效果，从而改善电子设备的用户体验。
具体地，电子设备还可以包括壳体500，壳体500开设有容纳槽510，摄像头模组设置于容纳槽510，容纳槽510的底面511与转动体220限位配合。其中，底面511为容纳槽510的槽底，该底面511可以在摄像头210的光轴方向上与转动体220相对，在转动体220的转动角度较大时，转动体220会碰到底面511，从而使得转动体220较难继续在当前方向上转动。此种情况下，底面511能够防止转动体220因转动角度过大而从转动腔110中掉出，从而提高电子设备的可靠性。
进一步地，支架100朝向底面511的表面和底面511可以均为平面，从而使得支架100朝向底面511的表面与底面511之间的距离更小，甚至可以使两者较为紧密地接触，以使电子设备的结构较为紧凑，减少摄像头模组的占用空间，使得电子设备的厚度尺寸较小，有利于电子设备的轻薄化设计。
在本发明实施例中，可转动模组200的重心和可转动模组200的几何中心的连线可以与底面511平行。在电子设备上安装摄像头模组时，此方案能够使得摄像头210的朝向与底面511垂直，保证摄像头模组能够安装到位，避免因摄像头模组在安装过程中装斜而导致其需要靠自身的防抖功能进行调整，占用一定的防抖范围，从而防止使用过程中出现较大抖动时，摄像头模组的防抖范围不够，进而提高电子设备的防抖效果。
可选地，壳体500可以具有顶端，可转动模组200的重心与顶端之间的距离为第一距离，可转动模组200的几何中心与顶端之间的距离为第二距离，第一距离可以大于第二距离。需要说明的是，壳体500的顶端是指在用户使用电子设备时，电子设备上位置相对较高的一端，也就是目前电子设备上常设置有后置摄像头模组的一端。此方案能够确保在电子设备上正确安装摄像头模组，从一开始保证摄像头模组与电子设备的相对位置关系，避免后续使用过程中，摄像头模组的朝向因重力，出现摄像头翻转，且摄像头的朝向为非正常使用的方向，进而导致用户无法顺利进行拍摄操作，最终提升用户体验。
为了避免摄像头210受到外界水汽的影响，在一种可选的实施例中，摄像头模组的外壁可以具有防水件，避免水汽进入摄像头模组，导致摄像头模组失效，从而提高电子设备的防护等级，进一步提高电子设备的可靠性。防水件的形状可以是环状结构，并设置于摄像头模组的转动体的边缘，并与摄像头抵接，使摄像头与转动体之间几乎没有间隙，可有效防止液体或潮湿气体损坏摄像头。当然，防水件还可以是设置在整个摄像头模组外侧的防水涂层，该防水件能有效防止摄像头模组与电子设备之间的间隙引起的液体或潮湿气体的侵入，从而造成的损坏。
基于本发明实施例公开的摄像头模组，本发明实施例还公开一种摄像头模组的控制方法，所公开的控制方法包括以下步骤。
S110、检测摄像头模组的抖动参数。
S120、根据上述抖动参数计算理论补偿量。
S130、根据上述理论补偿量生成第一控制信号。
S140、根据上述第一控制信号控制电磁性件工作，进而驱动可转动模组200以上述理论补偿量运动。
具体地，抖动参数可以是摄像头模组与被拍摄物之间的角度或距离等位置关系，本发明实施例中不限制。摄像头模组在使用过程中出现抖动时，电子设备可以检测到摄像头模组的抖动参数，电子设备能够根据抖动参数计算理论补偿量，同时根据理论补偿量生成第一控制信号，从而控制电磁性件通电。当电磁性件通电后，第一磁性件300和第二磁性件400之间产生力的作用，进而能够驱动可转动模组200以理论补偿量运动，以实现对摄像头210的补偿。这样使得进入摄像头210的光线保持稳定，从而能够较好地解决摄像头模组在使用过程中抖动的问题，进而能够有效地克服摄像头模组因抖动而导致成像模糊的问题。
摄像头模组通常具有自动调焦功能，因此，摄像头模组与被拍摄物之间的距离变化对 拍摄质量的影响较小，但是，当摄像头模组摆动时，摄像头模组不能正对被拍摄物，在被拍摄物反射的光线中，仅有少部分光线进入至摄像头模组，导致摄像头模组的成像质量较差。可选的实施例中，抖动参数可以为抖动角度，理论补偿量可以为旋转角度，可转动模组200以旋转角度运动，以使摄像头模组能够正对被拍摄物，以使摄像头210能够稳定地朝向被拍摄物，从而使得在被拍摄物反射的光线中，较多的光线能够进入至摄像头模组，进而使得摄像头模组的成像质量较高。
当摄像头模组出现意外状况时(例如目标电磁性件磁力不够、可转动模组200受其他外力阻挡或理论补偿量计算出错)，摄像头模组可能较难运动至拍摄所需的位置。基于此，在一种可选的方案中，在驱动可转动模组以理论补偿量运动之后，所公开的控制方法还可以包括如下步骤。
S150、检测摄像头模组的实际补偿量。
S160、计算上述实际补偿量与上述理论补偿量的偏差量。
S170、当上述偏差量大于或小于0时，根据上述偏差量生成第二控制信号。
S180、根据上述第二控制信号控制电磁性件工作，进而驱动可转动模组以上述偏差量运动。此方案能够进一步提高对摄像头210补偿的精度，防止摄像头210没有运动至拍摄所需的位置，从而能够提高摄像头模组的防抖精度，进而能够进一步提高摄像头模组的拍摄效果。
