Description

光学防抖装置、摄像头模组及电子设备
本申请要求于2021年10月30日提交中国专利局、申请号为202111278481.9,发明名称为“光学防抖装置、摄像头模组及电子设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及拍摄技术领域,尤其涉及一种光学防抖装置、摄像头模组及电子设备。
背景技术
具摄像功能的电子设备(例如手机、平板电脑等)进行摄像时,经常会因轻微抖动导致拍摄的照片会发虚、重影或模糊的情况,例如:人体在手持物体时,普遍存在一定程度的生理性抖动,在影像拍摄时人体往往处于移动状态,这些无规律的、非自主的抖动或运动震动会造成拍摄画面的模糊不清,用户体验感也差。因此,具有摄像功能的电子设备需要具有自动对焦(Automatic Focus,简称AF)功能、光学防抖(Optical image stabilization,简称OIS)功能。
在电子设备的轻薄化及多功能的发展趋势下,摄像模组的设计过程中,在满足光学防抖装置能够对电子设备的抖动进行高效精准的补偿校正的情况下,如何设计更小尺寸的光学防抖装置,实现摄像模组的小型化,为业界持续探索的课题。
发明内容
本申请提供一种光学防抖装置、摄像头模组及电子设备,光学防抖装置能够对电子设备的抖动进行高效精准的补偿校正的同时,还具有更小的尺寸,以满足摄像头模组的小型化设计需求。
第一方面,本申请实施例提供一种光学防抖装置,包括:图像传感器、驱动组件、第一连接件和第二连接件。驱动组件包括能够相对移动的固定件和活动件,活动件与图像传感器固定连接,固定件和活动件配合用于带动图像传感器沿第一方向和第二方向移动,第一方向和第二方向呈夹角设置;第一连接件包括第一连接部、第二连接部和第一弹性部,第一弹性部连接在第一连接部和第二连接部之间,第一弹性部用于实现第一连接部和第二连接部之间沿第一方向的相对移动,第一连接部与活动件固定连接;第二连接件与第一连接件层叠设置,第二连接件包括第三连接部、第四连接部和第二弹性部,第二弹性部连接在第三连接部和第四连接部之间,第二弹性部用于实现第三连接部和第四连接部之间沿第二方向的相对移动,第三连接部与固定件相对固定连接,第四连接部与第二连接部固定连接。
通过在第一连接件中设置第一弹性部,使得第一连接部和第二连接部能够在第一方向上相对移动,通过在第二连接件中设置第二弹性部,使得第三连接部与第四连接部能够在第二方向上相对移动,本申请实施例通过将层叠设置的第一连接件和第二连接件连接在驱动组件的固定件和活动件之间,实现驱动组件带动图像传感器沿第一方向和第二方向移动的传力机构,由于第一连接件和第二连接件层叠设置,第一连接件的第一弹性部负责第一方向移动过程中的弹性形变,第二连接件的第二弹性部负责第二方向移动过程中的弹性形变,本申请能够实现在有限的空间内,第一连接件和第二连接件在第一方向和第二方向上均具有较长的力 臂,驱动组件的力能够通过第一连接件和第二连接件实现较大的力矩,从而实现图像传感器的高效精准的位置补偿校正。
若将第一弹性部和第二弹性部设置在同一块板状结构(或者同一平面)上,第一弹性部和第二弹性部的长度必然受限,若要将第一弹性部和第二弹性部设置为足够长,必然需要将板状结构设置为足够大的面积,这样光学防抖装置和摄像头模组的尺寸就会非常大,不利于尺寸小型化的发展。可以理解的是,本申请提供的第一连接件和第二连接件均为平板式结构,由于第一连接件和第二连接件层叠设置,当第一连接件和第二连接件尺寸(指的是平板式第一连接件和第二连接件的面积)一定时,由于第一弹性部和第二弹性部设置在两个层叠设置的不同的平面(或平板)上,通过使第一弹性部在第二方向上的尺寸和第二弹性部在第一方向上的尺寸具有较大的设计空间能够最大化,从而力臂更长,输出的力矩更大,有利于将图像传感器移动至所需位置,以对电子设备的抖动进行高效精准的补偿校正。同时,当需要输出的力矩一定时,上述结构可以使得光学防抖装置的尺寸更小,从而满足摄像头模组对小型化的设计需求。
在一种可能的实现方式中,第一连接部和第二连接部在第二方向上的连接关系为刚性连接,即当驱动组件驱动图像传感器沿第二方向移动时,第一连接部和第二连接部同步移动,二者之间无相对移动的关系,可以理解为第一弹性部的弹性形变的方向仅为第一方向,在第二方向上,第一弹性部不具有弹性形变的能力。本方案有利于防止图像传感器在第一方向和第二方向上的移动的串扰,可以提升图像传感器移动的精度。
在一种可能的实现方式中,第三连接部和第四连接部在第一方向上的连接关系为刚性连接,即当驱动组件驱动图像传感器沿第一方向移动时,第三连接部和第四连接部同步移动,二者之间无相对移动的关系,可以理解为第二弹性部的弹性形变的方向仅为第二方向,在第一方向上,第二弹性部不具有弹性形变的能力。本方案有利于防止图像传感器在第一方向和第二方向上的移动的串扰,可以提升图像传感器移动的精度。
在一种可能的实现方式中,第一方向和第二方向所构成的移动平面与图像传感器的感光面平行(也可以理解为与图像传感器的成像面平行),或者,第一连接件和第二连接件所在的平面与图像传感器的感光面(或成像面)平行。本方案有利于防止图像传感器在第一方向和第二方向上的移动的过程中产生其它方向移动的串扰问题,若第一方向和第二方向所构成的移动平面相较图像传感器的感光面倾斜,会使得图像传感器产生旋转或摆动。因此本方案可以提升图像传感器移动的精度。
在一种可能的实现方式中,第一连接部位于第二连接部的外围,第三连接部位于第四连接部的外围。可以理解为,第二连接部位于第一连接件的中间区域,第四连接部位于第二连接件的中间区域,本实施方式将第一连接件和第二连接件的中间区域固定连接,第一连接件的边缘位置(第一连接部)与活动件固定连接,第二连接件的边缘位置(第三连接部)与固定件固定连接。也就是说,第一连接件和第二连接件与驱动组件的连接处位于外围边缘位置,外围边缘位置的尺寸较中间区域大,因此可以提升固定连接可靠性。具体而言,第一连接部和第二连接部同层设置,第三连接部和第四连接部同层设置,在实现第一连接部和第二连接部沿第一方向相对移动以及第三连接部和第四连接部沿第二方向相对移动的同时,还有利于减小第一连接件和第二连接件在垂直于第一方向和第二方向上的尺寸,减小光学防抖装置的尺寸。
在一种可能的实施方式中,第二连接部位于第一连接部的外围,第四连接部位于第三连接部的外围。本方案中,第一连接部位于第一连接件的中间区域,第三连接部位于第二连接件 的中间区域,将第一连接件和第二连接件的外围区域(也可以为边缘位置)固定连接,第一连接件的中间区域与活动件固定连接,第二连接件的中间区域与固定件固定连接。本方案提供了一种固定连接的方案,同样可以实现将第一连接件和第二连接件固定连接在活动件和固定件之间。
在一种可能的实施方式中,第一弹性部包括至少一条第一簧丝,第一簧丝包括与第一连接部相连的第一端、与第二连接部相连的第二端及连接在第一端和第二端之间的第一主体,第一主体与第一连接部和第二连接部之间均通过间隙间隔设置,第一主体在第二方向上延伸的距离大于等于图像传感器在第二方向上延伸的距离。通过将第一弹性部设置为簧丝,可以通过簧丝的弹性变形实现第一连接部和第二连接部之间的相对运动;通过使第一簧丝与第一连接部和第二连接部间隔设置,可以避免第一连接部和第二连接部相对运动时由于接触导致的摩擦阻力以及摩擦损害,同时还可实现电信号依次经过第一连接部、第一弹性部,传输至第二连接部,避免电信号传输过程中发生短路;通过使第一主体在第二方向上延伸的距离大于等于图像传感器在第二方向上延伸的距离,可以在第一连接件在沿第二方向的尺寸一定时,第一主体的尺寸实现最大化,使得第一弹性部在第一方向上的力臂更长,以使第一弹性部在第一方向上的弹性力更大,输出力矩也更大,驱动效率更高。
在一种可能的实施方式中,第一簧丝的数量为多个,多个第一簧丝依次间隔排列在第一连接部和第二连接部之间。通过增加簧丝的数量,可以更好地分配电迹线的布置,假设第一簧丝的数量为一个,多条电迹线需要布置在同一第一簧丝上,则会导致第一簧丝的宽度增加,第一簧丝的弹性相应变小,则弹力也变小。通过增加第一簧丝的数量,可以更好地对电迹线进行布置,且可以减小第一簧丝的宽度,增大第一簧丝的形变能力,从而保证第一弹性部弹性变形的能力。通过使多条第一簧丝在与第一连接部和第二连接部间隔设置,可以避免第一连接部和第二连接部相对运动时由于接触导致的摩擦阻力以及摩擦损害,同时还可实现电信号依次经过第一连接部、第一弹性部,传输至第二连接部,避免电信号传输过程中发生短路。
在一种可能的实施方式中,第一主体包括第一段和第二段,第二段相较第一段弯折延伸,第一端为第一段远离第二段的端部,第二端为第二段远离的述第一段的端部,第一段沿第二方向延伸。通过将第一主体分为相互弯折连接的第一段和第二段,第一段用于弹性变形,第二段用于固定,有利于延长第一簧丝在第一方向上的长度,从而能够输出更大的力矩。假设第一主体只包括第一段,第一簧丝在第一方向上的长度缩短了,力臂也就更短,输出的力矩也会相应减小。
在一种可能的实施方式中,第一主体呈直条状且沿第二方向延伸,第一主体的两端分别连接第二连接部和第一连接部。将第一弹性部设置为直条状,有利于保证弹力的方向的稳定性、保证力的方向。
在一种可能的实施方式中,第一弹性部的数量为两个,两个第一弹性部在第一方向上分别设置在第二连接部的两侧。通过使第一弹性部的数量为两个,且两个第一弹性部对称设置在第二连接部的两侧,使得第二连接件受力更加平衡,从而能够沿直线运动,有利于控制其移动距离,以将图像传感器精准调节至所需位置。
在一种可能的实施方式中,第二连接部的外边缘包括依次连接呈封闭框形的第一边、第二边、第三边和第四边,第一边和第二边相对设置,第三边和第四边相对设置;第一连接部包括第一连接片和第二连接片,第一连接片位于第一边的外围且与第一边之间通过间隙间隔设置,第二连接片位于第三边的外围且与第三边通过间隙间隔设置,其中一个第一弹性部位于第三边的外围且连接在第二连接片和第二连接部之间,另一个第一弹性部位于第四边的外 围且连接在第一连接片和第二连接部之间。通过使第一连接部包括第一连接片和第二连接片,且第一连接片和第二连接片分别对称设置在第二连接部的两侧,第二连接部的两侧同时受到第一连接片和第二连接片的作用力,从而在运动过程中始终保持受力平衡的状态,运动轨迹不会发生歪斜,有利于对图像传感器的位置进行精准调节。
在一种可能的实施方式中,其中一个第一弹性部与第二连接部连接的位置位于第三边上邻近第一边的位置,另一个第一弹性部与第二连接部连接的位置位于第四边上邻近第二边的位置。通过使第一连接片和第二连接片与第二连接部的连接位置对称设置,从而第一连接片与第二连接部之间的作用力和第二连接片与第二连接部之间的作用力相互平衡,从而避免第一连接部与第二连接部之间的相对运动发生倾斜和偏移,有利于对图像传感器的位置进行精准调节。
在一种可能的实施方式中,第一连接片和第二连接片之间的区域包括沿第一方向相邻设置的第一区域和第二区域,第二连接部和两个第一弹性部位于第一区域,第二区域用于容纳光学件,光学件用于将入射光传送至图像传感器。通过在第一连接片和第二连接片之间设置第二区域,既为光学件提供了安装空间,同时为光线进入图像传感器提供了通道。
在一种可能的实施方式中,光学件为转光件,光学件用于将入射光反射至图像传感器。通过在光学防抖装置中设置转光件,转光件可用于改变光线的光路,使光线垂直射入图像传感器,有利于减小摄像头模组的尺寸。通过在第一连接件中设置与图像传感器正对的第二区域,并将转光件容纳在第二区域,相比于将转光件设置于光学防抖装置外部的结构,有利于减小光学防抖装置的尺寸。
在一种可能的实施方式中,第二连接部包括第一连接主体和第一延伸部,第一延伸部的数量为两个,其中一个第一延伸部设置于第一边邻近第三边的位置,且与第一子弹性部连接;另一个第一延伸部设置于第二边邻近第四边的位置,且与第二子弹性部连接。本方案中通过设置第一延伸部代替第二段,同样能够实现第一弹性部与第二连接部在第一方向上为刚性连接,且第一连接主体在第二方向上长度最大化,以使第一连接件的力矩更大的目的。
在一种可能的实施方式中,第三连接部包围的区域包括沿第一方向相邻设置的第三区域和第四区域,第四连接部包括第二连接主体和第二延伸部,第二连接主体与第二连接部层叠设置且固定连接,第二连接主体位于第三区域,第二延伸部位于第四区域,部分第二弹性部位于第三区域,部分第二弹性部位于第四区域,第四区域与第二区域在层叠方向上相对设置。通过在第二连接件上设置第四区域,且第四区域与第二区域在层叠方向对称设置,使得光线能够在第二连接区域背向第一连接件的一侧射入图像传感器中;通过设置延伸部与第二弹性部连接,有利于延长第二弹性部在第一方向上的长度,从而能够输出更大的力矩。

此外,参阅图6和图8,固定件6包括磁性结构61和定子62,磁性结构61固定在定子62上,定子62与驱动板51相对间隔设置。本实施例中,定子62与第一线圈531和第二线圈532对应的位置均一一对应设有凹槽,凹槽的开口朝向驱动板51,磁性结构61容置于凹槽内,并通过胶粘的方式与凹槽内壁面固定,从而嵌设在定子62上。其他实施例中,磁性结构61还可以通过粘接、卡接等与定子62固定连接。磁性结构61包括第一磁极和第二磁极,可选地,第一磁极为N极,第二磁极为S极,磁感线由N极发射,并最终收敛于S极,从而形成磁场。当对第一线圈531和第二线圈532中通入电流时,该磁场用于与第一线圈531和第二线圈532配合产生推力,以推动活动件5移动。
实施例一中,定子62固定在底板41上,定子62还设有容纳槽641,一种实施方式中,容纳槽641与图像传感器1正对设置,其它实施方式中,容纳槽641只要位于图像传感器1入光的路径上,不一定要正对设置,根据需要设置的光学元件的特征,容纳槽641与图像传感器1之间也可以相对错开预设的位移。光转向件3容置于容纳槽641内并与定子62固定连接,定子62在将光转向件3固定在光学防抖装置40内的同时,通过开设容纳槽641容纳光转向件3,还有利于减小光学防抖装置40在垂直于图像传感器1的方向上的尺寸。
示例性地,当对第一线圈531通入电流时,第一线圈531在磁性结构61产生的磁场作用下,受到沿第二方向Y上的磁推力,第一线圈531推动活动件5沿第二方向Y移动;当对第二线圈532通电时,第二线圈532在磁性结构61的磁场作用下产生沿第一方向X上的磁推力,第二线圈532推动活动件5沿第一方向X移动。此外,当所通入的电流大小不同时,第一线圈531和第二线圈532产生的磁推力大小也不同,因此可以通过控制电流的大小以获得所需推力的大小,从而使得驱动组件M的效率和功率等满足需求。
通过使活动件5采用VCM为动力,直流电即可驱动,无需PWM驱动。且VCM具有较快的反馈速度,符合常规摄像场景需求。通过对流入线圈中的电流的方向和大小进行合理设计,即可达到根据需要调整光学防抖装置40的驱动效率,实现调整图像传感器1至所需的位置,有利于对外部环境震动进行反向补偿。

请参阅图28,图28是图23所示的第一连接件7在一些实施例中的结构示意图。第一连接件7包括第一连接部71、第二连接部72和第一弹性部73,第一弹性部73设置于第一连接部71和第二连接部72之间,并连接第一连接部71和第二连接部72。第一连接部71的包括第一连接片711、第二连接片712、第三连接片713和第四连接片714,第一连接片711和第二连接片712’相对设置,第三连接片713’和第四连接片714’相对设置。第二连接部72包括第五连接片721’、第六连接片722’、第七连接片723’和第八连接片724’,第一连接片711位于第五连接片721’的外围且与第五连接片721’通过间隙H1’间隔设置,第二连接片712位于第六连接片722’的外围且与第六连接片722’通过间隙H2’间隔设置,第三连接片713位于第七连接片723’的外围且与第七连接片723’通过间隙H3’间隔设置,第四连接片714位于第八连接片724’的外围且与第八连接片724’通过间隙H4’间隔设置。通过使第一连接部71和第二连接部72为外缘封闭,中部镂空的框形,封闭的外缘可用于第二连接部72之间的固定连接,中部镂空的结构与图像传感器1正对可用于光线透过。此外,第一连接部71和第二连接部72通过间隙间隔设置,也避免了第一连接部71和第二连接部72之间的运动干涉、电路短路等问题。
第一弹性部73包括第一子弹性部731和第二子弹性部732,第一子弹性部731位于第三连接片713与第七连接片723’之间,且连接第三连接片713与第七连接片723’,第二子弹性部732位于第四连接片714与第八连接片724’之间,且连接第四连接片714和第八连接片724’。第一子弹性部731包括第一簧丝,第一簧丝的第一端733与第一连接部71连接,且其连接位置位于第一连接片711邻近第三连接片713的位置,第二端734’与第六连接片722连接,且其连接位置位于第六连接片722邻近第七连接片723的位置。第一主体设置于第三连接片713与第七连接片723之间,且第一主体呈条状沿第二方向Y延伸,有利于保证弹力的方向的稳 定性,保证力的方向。第一主体与第三连接片713和第七连接片723之间均具有空气间隔,以避免与第一连接部71之间的运动干涉现象。第一主体包括沿第二方向Y延伸的第一段7351和沿第一方向X延伸的第二段7352,第一段7351与第二段7352连接,且第二段7352相较第一段7351呈直角弯折。当第一弹性部73受到沿第一方向X上的推力时,第一段7351在第一方向X上弹性变形,第二段7352在第一方向X上为刚性,以使第二连接部72与第一连接部71沿第一方向X相对运动。通过使第一簧丝包括弯折连接的第一段7351和第二段7352,第一段7351用于弹性变形,第二段7352用于固定,有利于延长第一弹性部73在第一方向X上的长度,从而能够输出更大的力矩,驱动效率更高。
请一并参阅图29和图30,图29为第一连接件7在一些可能的实施例中的结构示意图,图30为第一连接件7在另一些可能的实施例中的结构示意图。第二连接部72包括第一连接主体726和第一延伸部725,本实施例以第五连接片721和第六连接片722为例进行说明。两个第一连接主体726和两个第一延伸部725均沿第一方向X延伸,第一延伸部725与第一弹性部73连接处的边为如图26所示的与第一方向X呈夹角倾斜的斜边,也可以为如图27所示的与第一方向X平行的边。当第二连接部72上设有第一延伸部725时,第二簧丝只包括第一段7351,第一延伸部725用于代替第二段7352的刚性连接的作用。可以理解的是,其他实施例中,第一延伸部725的数量和形状等均可以根据实际需求进行设计。
在一些实施例中,请一并参阅图23和图31,图31为图23所示的第二连接件8在一些实施例中的结构示意图。第二连接件8设置于第一连接件7和活动件5之间。第二连接件8包括第三连接部81、第四连接部82和第二弹性部83,第三连接部81和第四连接部82均为外缘封闭,中部镂空的框形,第二弹性部83设置于第三连接部81和第四连接部82之间,并连接第三连接部81和第四连接部82。第二弹性部83包括第三子弹性部831和第四子弹性部832,第三子弹性部831的第一段8311沿第一方向X延伸,第二段8312沿第二方向Y延伸,第三子弹性部831和第四子弹性部832对称设置在第四连接部82沿第二方向Y的两侧。第三子弹性部831和第四子弹性部832的结构与第一弹性部73的结构相同,参考即可,此处不再赘述。
当第二弹性部83受到沿第二方向Y上的推力时,第一段8311在第二方向Y上弹性变形,第二段8312在第二方向Y上为刚性,以使第四连接部82与第三连接部81沿第二方向Y相对运动。通过设置两个第二弹性部83,并使两个第二弹性部83分别设置在第四连接部82沿第二方向Y上相对的两侧,可以使第三连接部81和第四连接部82之间的相互作用力更加均匀和对称,使得第三连接部81和第四连接部82之间的相对运动更加平衡。
其他实施例中,第四连接部82还可以包括第二连接主体和第二延伸部,其数量、结构均可参考第一连接件7的第一连接主体和第一延伸部的数量和结构设置。
请一并参阅图22、图32和图33,图32为图22沿D-D处剖开的结构示意图,图33为图22沿E-E处剖开的结构示意图。第二连接件8与第一连接件7层叠设置,活动件5包括弯折部52,弯折部52由驱动板51朝向第一连接件7所在侧延伸,弯折部52的数量为两个,两个弯折部52在驱动板51沿第二方向Y的两侧对称设置,第一连接件7与弯折部52连接并围合形成一个两端开口的容纳腔,两个开口设置在驱动板51沿第一方向X的两侧。第二连接件8设置该容纳腔内,并通过容纳腔的两端的开口与中框42连接。图32和图33所示的方案中,第一连接件7、弯折部52和驱动板51共同围合形成容纳空间,第二连接件8设置于容纳空间中,固定件6位于驱动板51背离第二连接件8的一侧。本方案中通过将第二连接件8设置于容纳空间内,固定件6位于驱动板51板背离第二连接件8的一侧,同样可以达到 使得光学防抖装置的结构更加紧凑,有利于减小光学防抖装置的整体体积的目的。
实施例二中,第一连接部71设置在第二连接部72外围,第三连接部81设置在第四连接部82外围。第一连接部71与弯折部213固定连接,第二连接部72与第四连接部82固定连接,第三连接部81与中框42固定连接。当驱动板51沿第一方向X运动时,弯折部213带动第一连接部71沿第一方向X运动,由于第二弹性部83在第一方向X上为刚性,且第三连接部81与中框42固定,因此第二连接件8整片保持固定,第二连接部72与第四连接部82固定连接而保持固定,此时,第一弹性部73沿第一方向X变形,第一连接部71与第二连接部72在第一方向X上相对运动。当驱动板51沿第二方向Y运动时,弯折部213带动第一连接部71沿第二方向Y运动,由于第一弹性部73在第二方向Y上为刚性,因此弯折部213带动第一连接件73整片沿第二方向Y移动。第二连接部72带动第四连接部82沿第二方向Y运动。由于第三连接部81与固定件6相对固定连接,此时第二弹性部83沿第二方向Y变形,使得第四连接部82与第三连接部81在第二方向Y上相对移动。此外,第一连接件7背向驱动板51的一侧与第一电路板63固定连接,当驱动板51带动第一连接部71运动时,第一连接部71带动第一电路板63同步移动,从而达到移动图像传感器1的目的。
类似地,还可以为第二连接部72设置于第一连接部71外围,第四连接部82设置于第三连接部81外围,其具体连接结构参考实施例一中的描述即可,此处不再赘述。
在一些实施例中,请参阅图33和图34,图34是图22所示的光学防抖装置40在一些实施例中的局部结构示意图。第一连接件7包括第一基板74,第一线路层75和第三线路层76,第一线路层75和第三线路层76分别设置在第一基板74相背的两个表面上,且第一线路层75设有第一电迹线,第三线路层76上设有第二电迹线。第一基板74上开设有导电通孔K5,导电通孔K5贯穿第一线路层75、第一基板74和第三线路层76,通过在导电通孔K5内涂覆绝缘层,然后填充导电材料,绝缘层用于将导电材料与第一基板74绝缘,导电材料用于实现第一线路层75和第三线路层76的电连接。图像传感器1的电信号依次经过第一电路板63、活动件5、第一线路层75和第三线路层76传输至第四连接部82,再依次通过第二弹性部83、第三连接部81传输至外部电路。
