Description

联动装置、摄像模组及电子设备
本申请要求2020年07月01日在中国提交的申请号为202010638092.1、名称为“联动装置、摄像模组及电子设备”的专利申请的优先权，其全部内容通过引用并入本文。
技术领域
本申请涉及摄像模组的技术领域，特别涉及一种联动装置、摄像模组及电子设备。
背景技术
近年来，在手机的摄像模组上实现特定倍率的光学变焦的功能，更容易获得消费者的青睐。而为了实现某些固定倍率的光学变焦，镜头会随着载座的移动而到达指定位置，以实现变焦和对焦。
但是，一般摄像模组中载座的位置控制精度较差，位于载座上的镜头实现的是某些特定倍率的变焦，并不能实现连续变焦，摄像模组的实际成像效果较差。
发明内容
本申请的目的在于提供一种联动装置、摄像模组及电子设备，以解决一般摄像模组不能实现连续变焦等问题。
为了解决上述技术问题，本申请提供了一种联动装置，用于连续变焦的摄像模组中。联动装置包括：基座、以及与所述基座滑动连接的第一载座和第二载座；所述基座上设有第一定位元件，所述第一载座上设有第一感应元件和第二定位元件，所述第二载座上设有第二感应元件；所述第一感应元件与所述第一定位元件相对设置，以检测所述第一载座相对所述基座的位置；所述第二感应元件与所述第二定位元件相对设置，以检测所述第二载座相对所述第一载座的位置。基于此，通过将第一载座作为参照物来检测第二载座的相对位置，当作为参照物的第一载座运动时，第二载座与第一载座的相对位置关系也发生变化；此变化可以通过第二感应元件和第二定位元件的配合来实现获取。相应的，该第二载座能够快速响应第一载座的运动而实现同步运动，从而提高对第二载座的位置控制精度。例如：第一载座在位置A，第二载座在位置B(两个位置通常较接近)，现在需要将第一载座移动到位置C，将第二载座移动到位置D来完成某倍率的变焦和对焦。由于现有的感应元件以及定位元件受制造、工艺水平等因素影响，无法实现对长距离的高精度控制，因此，载座在长距离移动时，控制精度会较低，例如，第一载座通常不能准确地移动到位置C，而是在C附近一个位置；同理，第二载座受控制精度的影响，通常也在位置D附近，这样，最终第一载座与第二载座都会存在误差，从而使得第一载座与第二载座之间的对焦距离(D-C)存在着更大的误差，而这个对焦距离是影响成像效果的非常关键的因素，因此会造成摄像模组的实际成像效果较差。而本申请提供的联动装置，基于将第一载座和第二载座的运动关系设置成联动，当第一载座从位置A朝向位置C运动时，第二载座与第一载座之间的相对位置关系会发生变化；此变化通过第二感应元件和第二定位元件的配合实现获取。由此，第二载座会快速响应第一载座的移动而同步运动，以从位置B朝向位置D移动。进而，通过第二感应元件和第二定位元件的配合，第二载座会配合相关的控制电路和/或控 制芯片而再次检测与第一载座的相对位置关系，以此形成闭环检测系统。可以理解，在第一载座从位置A移动到位置C过程中，每次都可以通过一定的短的步长来控制，这个步长的距离相比于从A到C的距离要短得多，现有的感应元件与定位元件的对于短距离的控制精度很高，从而使得第二载座可以高精度地跟随第一载座到达位置C；然后第二载座再移动一段距离到达位置D，这样，本申请中的对焦距离的误差主要是通过第二载座从C移动到D引起的，相比于现有方案，受误差影响的距离更短(本申请第二载座只有D-C段有误差，现有的是第二载座D-B段有误差，同时，第一载座C-A段也有误差)，且受误差影响的因素更少(只有第二载座移动有误差，而现有技术第一载座，第二载座都需要移动，都会产生误差)。从而使得最终对焦距离的误差更小，可以实现更高精度的某倍率的变焦和对焦，提高了成像效果。

具体实施方式
下面将结合本申请实施方式中的附图，对本申请实施方式中的技术方案进行清楚、完整地描述。
一般的光学变焦的摄像模组中，包含至少两组可动镜群，其用于实现某些固定倍率变焦的透镜组件需要在一定范围内移动，以通过相对位置的改变来实现变焦，其用于实现对焦的透镜组件也需要在一定范围内移动，以实现对焦。对此，一般的摄像模组还会设置音圈马达，通过音圈马达提供的推力以驱动相应的载座移动。同步地，载座的移动可以同步带动载座上的透镜组件移动，以促使变焦的透镜组件到达预定的位置。
由于变焦的透镜组件应承载在载座上；相应的，该透镜组件的相对位置也是基于载座的相对位置而确定。即，载座的位置精准度与对应的透镜组件的变焦精准度紧密关联。应当理解，在摄像模组中，实现固定倍率变焦的透镜组件对于载座的运动精度要求很高。但在实际的使用过程中，一般的摄像模组由于马达运动系统的结构设计以及马达运动检测控制系统等的限制，载座的控制和位置反馈并不及时，导致该些载座的检测精度较低。
基于此，当一般的摄像模组需要实现某些固定倍率的变焦时，马达载座实际移动到的位置与预定的位置存在一定的偏差；同步地，马达载座上的透镜组件的实际位置也会与预定的位置存在一定的偏差。此类位置偏差的影响在变焦的领域显得相对突出，一定程度上影响用户对使用该些摄像模组的电子设备的体验。
例如：第一载座在位置A，第二载座在位置B，现在第一载座需要运动到位置C，第二载座需要运动到位置D来完成×3倍率的变焦和对焦。但是，定位元件和感应元件受到制造工艺、材料等因素影响，相关的载座的运动并不是很好控制；即，该些载座的位置控制精度较低，第一载座可能移动到位置C+或者位置C-上，第二载座可能移动到位置D+或者位置D-上。
应当理解，位置C+、位置C-与位置C不同，位置D+、位置D-也与位置D不同；由此，通过一般的摄像模组而形成的图像容易出现失焦或者模糊等问题；该些摄像模组的成像效果会比较差，用户对该些图像的接受程度也相对较低。
基于以上的问题，请同时参阅图1至图7，本申请实施例提供了一种用在摄像模组中的联动装置、摄像模组以及电子设备。该联动装置100可以承载相关的透镜组件(1100，1200)，以配合该些透镜组件实现变焦和对焦，以实现连续光学变焦的功能。
当应用该摄像模组的电子设备进行摄像时，摄像模组内的联动装置可以带动相关的透镜组件移动，精准地使该些透镜组件移动到预定的位置，由此摄像模组可以实现特定倍率的变焦和对焦，以提高用户的拍摄体验。
为了便于理解本申请各实施例的技术方案，各实施例中主要是将第一载座作为承载变焦的第一透镜组件的载座，将第二载座作为承载对焦的第二透镜组件的载座，将广泛使用的手机作为电子设备，以此进行举例说明。但也应当理解，第一载座和第二载座也可以根据需求而承载其他类型的透镜组件；电子设备也可以是指平板电脑、笔记本电脑、车载监控仪、显示器等等设备，本申请对此不加限制。
图1是第一透镜组件、第二透镜组件和图像传感器的示意图，图2是联动装置的立体图，图3是联动装置的剖视图。请同时参阅图1至图3，本申请实施例提供的一种联动装置100，包括基座110、第一载座120和第二载座130。该基座110具有滑动轴112，滑动轴112可以供第一载座120和第二载座130依次穿设。如图2和图3，滑动轴112的数量示例为两根，以使第一载座120和第二载座130的滑动相对稳定。应当理解，该滑动轴112的数量可以根据需求而有所调整，滑动轴112的数量也可以是一根或者三根等等。
对应的，第一载座120和第二载座130均能够与基座110滑动连接，并通过基座110的滑动轴112来限定各自的运动方向。基于此，第一载座120和第二载座130可以在对应的马达的驱动下，沿着滑动轴112的长度方向运动，以分别改变各自的相对位置。基于第一载座120的移动，可以同步地带动第一透镜组件1100移动，基于第二载座130的移动，也可以同步地带动第二透镜组件1200移动；由此，促使第一透镜组件1100和第二透镜组件1200配合以实现不同倍率的变焦和对焦。
本申请各实施例为了提高第一载座120和第二载座130的位置控制精度，将第一载座120和第二载座130的运动设置成关联运动；即，第二载座130的运动和第一载座120的运动关联。当第一载座120运动时，第二载座130也会响应第一载座120的运动而对应运动，由此可以提高第一载座120和第二载座130的位置控制精度。
通过关联运动的构思，可以提高第一载座120和第二载座130对位置控制的精准度。由此，第一载座120上的第一透镜组件1100可以精准地移动到预定的位置，以实现特定倍率的变焦。第二载座130的第二透镜组件1200也可以快速响应而精准地移动到预定的位置，以实现对焦。
应当理解，当第一载座120和第二载座130关联运动时，第一载座120和第二载座130各自的速度可以根据使用需求而有所调整。即，第一载座120和第二载座130的运动速度可以不同，而不应当理解第一载座120和第二载座130的运动速度相同。
图4是联动装置的俯视图，图5是联动装置的爆炸示意图。请同时参阅图2、图3、图4和图5，一些实施例中，第一载座120包括第一承载部122和第一延长部124。第一承载部122可以承载第一透镜组件1100，以带动第一透镜组件运动。第一承载部122还具有对应滑动轴112的通孔(图未示)，该第一承载部122的通孔可以供滑动轴112穿过，以使第一载座120能够通过滑动轴112实现滑动。由此，在第一承载部122被对应的马达驱动而沿着滑动轴112运动时，该第一承载部122可以同步带动第一透镜组件运动，以改变第一透镜组件的位置。藉由位置的改变，第一透镜组件可以实现特定倍率的变焦。
而为了确定第一承载部122的位置以同步确定第一透镜组件的位置，各实施例中是通过在第一载座120和基座110之间建立位置关联来实现的；即，通过将基座110作为参照物来确定第一载座120的相对位置。对此，基座110上设置有第一定位元件142，第一载座120的第一延长部124上则设置有对应第一定位元件142的第一感应元件144。
一些实施例中，例如图2、图4和图5等附图所标示出的第一感应元件144，其实是位于第一延长部124的一侧并且朝向第一定位元件142，此可以配合图3的剖视图来进行理解。
图6是联动装置的局部示意图。如图2至图6所示例的，第一延长部124位于第一承载部122的一侧，并且朝向基座110的方向延伸。基于第一延长部124的延伸结构，当第一承载部122在滑动轴112上滑动时，第一延长部124上的第一感应元件144均可以始终与基座110上的第一定位元件142保持感应的关系，以此通过第一感应元件144和第一定位元件142的配合来确定第一载座120的相对位置。而由于第一载座120的位置确定，同步可以确定第一透镜组件的位置，便于控制第一透镜组件的位置以实现特定倍率的变焦。
一些实施例中，第一定位元件142和第一感应元件144相对设置。第一载座120在运动的过程中，第一定位元件142和第一感应元件144可以是始终保持着正对的关系，以配合而获取第一载座120的位置信息；或者，在一些情况下，第一定位元件142和第一感应元件144可以是错开一定的距离，但是第一定位元件142和第一感应元件144依旧可以配合而实现对第一载座120的位置信息的获取。
请同时参阅图2至图5，一些实施例中，第二载座130包括第二承载部132。第二承载部132可以承载第二透镜组件，以带动第二透镜组件运动。类似的，第二承载部132也具有对应滑动轴112的通孔(图未示)，该第二承载部132的通孔可以供滑动轴112穿过，以使第二载座130能够通过滑动轴112实现滑动。由此，在第二承载部132被对应的马达驱动而沿着滑动轴112运动时，该第二承载部132可以同步带动第二透镜组件运动，以改变第二透镜组件的位置。藉由位置的改变，第二透镜组件可以实现对焦的功能。
而为了确定第二承载部132的位置以同步确定第二透镜组件的位置，各实施例的联动 装置100是通过在第二载座130和第一载座120之间建立关联的位置关系来实现的；即，通过将第一载座120作为动态的参照物来对应确定第二载座130的相对位置。对此，第一载座120上还设置有第二定位元件146，第二载座130上则设置有对应第二定位元件146的第二感应元件148。通过第二感应元件148和第二定位元件146的配合来确定第二载座130的相对位置。而由于第二载座130的位置确定，可以同步地确定第二透镜组件的位置，便于控制第二透镜组件的位置以实现对焦。
以各实施例的联动装置100应用到手机中来举例说明，当该联动装置100用于手机中，基于用户所选择的特定倍率的焦距，第一载座120会带动第一透镜组件运动，第二载座130也会带动第二透镜组件运动，以此来实现特定倍率的变焦和对焦。
一些实施例中，第二定位元件146和第二感应元件148相对设置。第一载座120和第二载座130在运动的过程中，第二定位元件146和第二感应元件148可以是始终保持着正对的关系，以配合而获取第一载座120的位置信息；或者，在一些情况下，第二定位元件146和第二感应元件148可以是错开一定的距离，但是第二定位元件146和第二感应元件148依旧可以配合而实现对第二载座130的位置信息的获取。
应当理解，通过将第一载座120作为参照物来检测第二载座130的相对位置，当作为参照物的第一载座120运动时，第二载座130与第一载座120的相对位置关系也发生变化；此变化可以通过第二感应元件148和第二定位元件146的配合来实现获取。相应的，通过调整驱动第二载座130运动的马达的驱动力方向和作用时间等方式，该第二载座130能够快速响应第一载座120的运动而实现同步运动。而后，通过第二感应元件148和第二定位元件146的配合可以再次检测第二载座130相对第一载座120的位置，由此形成一个闭环检测系统。通过多次的闭环检测，可以精准地控制第二载座130与第一载座120之间的相对位置关系，促使第二载座130更精准地运动到预定的位置，从而提高对第二载座130的位置控制精度。
当第一载座120载着第一透镜组件、以及第二载座130载着第二透镜组件分别到达预定的位置后，先通过调节第一载座120上的第一透镜组件而完成变焦的操作，再通过调节第二载座130，第二载座130细微运动以使第二载座130上的第二透镜组件完成对焦的操作。基于此，使用该联动装置100的手机可以精准地实现变焦和对焦的操作，以供用户获取所需倍率的照片并提高用户的拍摄体验。
一些实施例中，第一感应元件144基于对第一定位元件142的感应，相应产生第一感应信号；该第一感应信号包括了第一载座120相对基座110的位置信息。第二感应元件148基于对第二定位元件146的感应，相应产生第二感应信号；该第二感应信号包括了第二载座130相对第一载座120的位置信息。
该第一感应信号和该第二感应信号可以传输至摄像模组的控制电路。相应的，控制电路可以根据第一感应信号得到第一载座120的位置信息，根据第二感应信号得到第二载座130的位置信息。而由于第二感应信号中关于第二载座130的位置信息是基于第一载座120而确定的；基于此，根据第一感应信号和第二感应信号，控制电路可以更好地确定基座110、第一载座120和第二载座130之间的相对距离，以提高对第一载座120和第二载座130的位置控制精度，并更为精准地控制该两个载座运动。
图7是联动装置在另一视角下的局部示意图。请同时参阅图2、图3、图4、图5和图 7，一些实施例中，为了实现第二载座130和第一载座120之间的关联运动，第一载座120还包括第二延长部126。对应于第一延长部124，该第二延长部126也是位于第一承载部122的一侧。但是与第一延长部124不同，该第二延长部126是朝向第二载座130的方向延伸。第二延长部126上设有对应第二感应元件148的第二定位元件146。第二载座130除了第二承载部132外，还包括第一凸起部134。该第一凸起部134位于第二承载部132的一侧，并且在第一凸起部134上设置有第二感应元件148。应当理解，相对滑动轴112，第二延长部126和第一凸起部134是处于同一侧，由此使得第一凸起部134上的第二感应元件148能够与第二延长部126上的第二定位元件146配合。
一些实施例中，例如图4和图7等附图所标示出的第二感应元件148，其实是位于第一凸起部134的一侧并且朝向第二定位元件146，此可以配合图3的剖视图、图5的爆炸图等附图来进行理解。
一些实施例中，沿着滑动轴112的长度方向，第二延长部126的长度大于第一凸起部134的长度。基于此，在第一载座120和第二载座130关联运动的过程中，第一凸起部134上的第二感应元件148可以始终与第二定位元件146保持感应的关系，以此通过第二定位元件146来检测第二载座130的相对位置。
一些实施例中，为了便于理解第一载座120的相关结构的位置关系，以下通过第一承载部122包括第一端、第二端、第一侧和第二侧来举例说明。应当理解，第一端和第二端是第一承载部122的对向的两端；第一端示例为第一承载部122之靠近基座110的一端，第二端示例为第一承载部122之靠近第二载座130的一端。第一端到第二端的方向或者第二端到第一端的方向即可以等效为滑动轴112的长度方向。第一侧和第二侧是第一承载部122的对向的两侧。第一侧和第二侧可以等效为第一承载部122相对滑动轴112的两侧。
基于上述对第一承载部122的定义，第一延长部124示例为位于第一承载部122的第一侧，并且第一延长部124的延伸方向是从第二端到第一端的方向。而由于第二感应元件148和第一感应元件144对位置的检测是相对独立的，因此，第二延长部126可以位于第一承载部122的第一侧；或者，第二延长部126也可以位于第一承载部122的第二侧。但应当理解，与第一延长部124相反，该第二延长部126的延伸方向是从第一端到第二端的方向，并且第二载座130的第一凸起部134与第二延长部126同侧，以使第二感应元件148可以感应到第二定位元件146。
请再参阅图2至图5以及图7，一些实施例中，为了降低在一些极端情况下第一凸起部134存在偏离第二延长部126的长度范围的可能，第二延长部126在远离第一承载部122的端部设有第一限位块128。通过第一限位块128、第二延长部126和第一承载部122的配合，可以将第一凸起部134限定在第一限位块128和第一承载部122之间，以使第二感应元件148和第二定位元件146之间的距离不会超过最大的感应距离。
应当理解，在一些极端情况下，比如：使用该联动装置100的手机从高空跌落或者被相对剧烈地晃动等等，第二载座130和第一载座120之间可能相互远离，并使得第二感应元件148无法与第二定位元件146配合以检测位置。在此实施例中，基于第一限位块128的结构，当第二载座130即将远离第一载座120时，通过第一限位块128抵住第一凸起部134的方式，可以确保第一凸起部134位于第二延长部126的长度范围内。对应的，第一凸起部134上的第二感应元件148依旧能够与第二延长部126上的第二定位元件146配合， 以检测第二载座130相对第一载座120的位置。
一些实施例中，该第一限位块128和第二延长部126可以是通过相同材料一体成型制成，以提高整体强度。比如：该第一限位块128和第二延长部126的材料均为高分子聚合物。
在其他的一些实施例中，该第一限位块128和第二延长部126可以是相对独立的两个部件，并通过粘接、焊接、螺接或者过盈配合等形式实现固定。
在其他的一些实施例中，第二载座包括第二承载部和第三延长部，而没有第一凸起部。该第三延长部位于第二承载部之朝向第一载座的一端，并且朝向第一载座的方向延伸；第三延长部上设有第二感应元件。
对应第二载座的结构，第一载座则没有第二延长部，而是包括第一承载部、第一延长部和第二凸起部；第二凸起部上设有第二定位元件。一些实施例中，该第二凸起部和第一延长部位于第一承载部的同一侧。在其他的一些实施例中，该第二凸起部和第一延长部位于第一承载部的不同侧，对此不加限制。
应当理解，第三延长部和第二凸起部的关系，类似于其他实施例中第二延长部和第一凸起部的关系，同样可以便于第二感应元件和第二定位元件配合，以实现位置检测的功能。
一些实施例中，第三延长部在远离第二承载部的端部也可以设置有相应的第二限位块，以将第二凸起部限定在该第二限位块和第二承载部之间。类似其他实施例中的第一限位块，当第二载座即将远离第一载座时，通过该第二限位块抵住第二凸起部的方式，可以确保第二凸起部位于第三延长部的长度范围内。对应的，第二凸起部上的第二感应元件依旧能够与第三延长部上的第二定位元件配合，以检测第二载座相对第一载座的位置。
请参阅图2至图6，一些实施例中，为了提高第一载座120的整体强度，第一承载部122、第一延长部124和第二延长部126可以是一体成型的载座结构。在其他的一些实施例中，当第一载座120包括第二凸起部时，第一承载部122、第一延长部124和第二凸起部同样可以一体成型。
请参阅图2至图5以及图7，一些实施例中，为了提高第二载座130的整体强度，第二承载部132和第一凸起部134可以是一体成型的载座结构。在其他的一些实施例中，当第二载座130包括第二承载部132和第三延长部时，第二承载部132和第三延长部同样也可以一体成型。
一些实施例中，第一定位元件142和第二定位元件146均为磁石；比如：第一定位元件142和第二定位元件146均为长条形的磁石，以便于与对应的感应元件相配合而实现位置检测。对应的，第一感应元件144和第二感应元件148均为霍尔传感器；霍尔传感器可以通过感应磁场的相对变化来实现对位置的检测。
在其他的一些实施例中，第一定位元件142和第二定位元件146均为霍尔传感器。基于此，第一感应信号则是由第一定位元件142产生，第二感应信号则是由第二定位元件146产生。对应的，第一感应元件144和第二感应元件148均为磁石；比如：第一感应元件144和第二感应元件148均为长条形的磁石，以便于与对应的定位元件相配合而实现位置检测。
在另一些实施例中，两个定位元件也可以不一样，一个是磁石，另一个是霍尔传感器，相应地，对应的两个感应元件一个霍尔传感器，另一个是磁石，从而可以与两个定位元件分别配合。
一些实施例中，为了驱动第一载座120运动，第一载座120上可以设有第一驱动线圈，基座110上可以对应设有第一驱动磁石；第一驱动线圈与第一驱动磁石组成第一音圈马达。基于此，第一音圈马达可以驱动第一载座120运动，以改变第一透镜组件的相对位置。类似的，第二载座130上可以设有第二驱动线圈，基座110上可以对应设有第二驱动磁石；第二驱动线圈与第二驱动磁石组成第二音圈马达。基于此，第二音圈马达可以驱动第二载座130运动，以改变第二透镜组件的相对位置。
图8是第一载座和第二载座的相对运动示意图。请参阅图8，一些实施例中，类似上述的例子，第一载座120在位置A，第二载座130在位置B，现在第一载座120需要运动到位置C，第二载座130需要运动到位置D来完成×3倍率的变焦和对焦。基于本申请实施例提供的联动装置，第一载座120和第二载座130的运动相关联，当第一载座120从位置A朝向位置C运动时，第二载座130与第一载座120之间的相对位置关系会发生变化；此变化通过第二感应元件和第二定位元件的配合实现获取。由此，第二载座130会快速响应第一载座120的移动而同步运动，以从位置B朝向位置D移动。进而，通过第二感应元件和第二定位元件的配合，第二载座130会配合相关的控制电路和/或控制芯片而再次检测其与第一载座120的相对位置关系，以此形成闭环检测系统。通过多次的闭环检测，第二载座130与第一载座120之间的相对位置反馈更为精准，以此可以促使第一载座120精准地运动到位置C，第二载座130精准地运动到位置D，进而实现×3倍率的变焦和对焦。
请同时参阅图1至图8，一些实施例中，当联动装置100应用到摄像模组中，该摄像模组还包括一些用于捕获图像信息的结构。比如：摄像模组还包括图像传感器1300，该图像传感器1300被配置在第二透镜组件1200的一侧并且远离第一透镜组件1100，以捕获相关的图像信息。
在其他的一些实施例中，摄像模组还可以包括其他的一些必要或者非必要的结构。比如：摄像模组还包括反射镜，该反射镜可以改变外界光线的入射角度。由此，当摄像模组应用到手机中，联动装置100可以沿着手机的长度方向或者宽度方向设置，以具有较长的变焦和对焦行程。基于此，相应可以提高手机的拍摄效果，并提高用户对手机的使用体验。
以上所述是本申请具体的实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
