如图3至图6所示所示,在本申请的一个实施例中,镜头对焦部分23进一步包括一对焦保持部234,以使得对焦载体2311在移动过程中始终保持于基座21内。进一步的,对焦保持部234包括对焦磁吸构件2341和对焦支持构件2342,对焦磁吸构件2341被设置于对焦可动部231的周侧中的一侧,对焦支持构件2342被设置于对焦可动部231的周侧中的一侧,其中,对焦支持构件2342与对焦磁吸构件2341设置于对焦可动部231的异侧。在本申请一具体示例中,对焦磁吸构件2341被设置于对焦可动部231,对焦磁吸构件2341与对焦磁石2321相对设置,对焦磁吸构件2341与对焦磁石2321之间产生沿水平方向的磁吸力,以使得焦磁吸构件2341与对焦磁石2321沿水平方向相互吸引。一方面使得对焦载体2311始终被保持于基座21内,另一方面通过磁吸力的作用使得对焦载体2311在移动后能够回复到初始位置。
在本申请的一个实施例中,对焦磁吸构件2341设置于对焦载体2311的侧壁,对焦磁吸构件2341设置于对焦磁石2321所在的一侧,以使得对焦磁吸构件2341与对焦磁石2321能够相对设置。例如,对焦磁石2321设置于第一侧101,对焦磁吸构件2341也设置于第一侧101,对焦磁吸构件2341与对焦磁石2321之间产生的磁吸力的方向垂直于光轴方向,磁吸力的作用使得对焦载体2311被保持于基座21的一侧;在本申请另一具体示例中,对焦磁吸构件2341与对焦磁石2321间产生的磁吸力的方向与光轴方向的夹角为锐角,磁吸力在垂直于光轴方向上的分力使得对焦载体2311被保持于基座21的一侧。
进一步地,对焦磁吸构件2341与对焦驱动部232设置于镜头对焦部分23的同一侧,例如,对焦磁吸构件2341与对焦驱动部232均设置于镜头对焦部分23的第一侧101。具体的,所述对焦线圈2322具有靠近所述对焦磁石2321的一侧和远离所述对焦磁石2321的一侧,所述对焦磁吸构件2341设置于所述对焦线圈2322远离所述对焦磁石2321的一侧,所述对焦磁吸构件2341与所述对焦磁石2321相对设置。在本申请一具体示例中,对焦磁吸构件2341可以通过嵌件注塑工艺一体成型于对焦载体2311。当然,在本申请另一具体示例中,对焦磁吸构件2341也可以通过粘接、焊接等方式固定于对焦载体2311,本申请对此不做限制。

继续如图3至图6所示,在本申请的一个实施例中,对焦支持构件2342被设置于对焦可动部231的周侧中的一侧,对焦支持构件2342设置于对焦载体2311与基座21之间,对焦载体2311在对焦支持构件2342的作用下始终被支撑于基座21,对焦支持构件2342在对焦磁吸构件2341的作用下被夹持于对焦可动部231与基座21之间。其中,对焦支持构件2342包括第一滚珠安装部23421、第二滚珠安装部23422,以及被夹持于第一滚珠安装部23421和第二滚珠安装部23422之间的对焦滚珠23423。第一滚珠安装部23421设置于对焦载体2311的一侧壁,第二滚珠安装部23422设置于基座21的一侧壁,第一滚珠安装部23421和第二滚珠安装部23422设置于镜头对焦部分23的同一侧,对焦滚珠23423被夹持于第一滚珠安装部23421与第二滚珠安装部23422之间,以提高对焦基座21在光学对焦过程中运动的稳定性,提高成像质量。
具体地,第一滚珠安装部23421为沿Z轴方向的轨道,第二滚珠安装部23422为Z轴方向的轨道,由于对焦滚珠23423设置于沿Z轴方向的轨道内,对焦滚珠23423的运动轨迹被限制在沿Z轴方向的轨道内,对焦滚珠23423可以在轨道内移动,以为对焦载体2311的移动提供支撑。第一滚珠安装部23421和第二滚珠安装部23422中分别设置有两颗对焦滚珠23423,以满足对焦载体2311移动行程的需求。进一步地,第二滚珠安装部23422中设置有一挡板,挡板将第二滚珠安装部23422分隔为两个安装区,两颗对焦滚珠23423被分别容置于两个安装区内,以避免两颗对焦滚珠23423在移动过程中碰撞在一起,而造成对焦载体2311倾斜。

将防抖磁石2422与对焦磁石2321共用,即镜头对焦部分23与芯片防抖部分24共用部分磁石,对应的共用磁石既能够提供对焦线圈2322所需的磁场,与对焦线圈2322作用实现镜头对焦,又能够提供防抖线圈2421所需的磁场与防抖线圈2421作用实现芯片防抖。如此,使得减少结构件,结构实现紧凑,降低光学组件的尺寸,从而实现驱动装置20以及模组结构的小型化。
通过将共用磁石安装在由第一向上延伸部2111、第二向上延伸部2112以及顶部横向延伸部212形成的安装位上,共用磁石沿光轴贯穿于镜头对焦部分23和芯片防抖部分24,在提供足够大的对焦磁场的同时,与防抖线圈2421的距离同样满足提供足够的防抖磁场,使得仅在单一方向上占据一定的高度和厚度尺寸,减少驱动装置20的横向尺寸,其余方向上为其他部件的设置预留空间,在充分利用内部结构的情况下,实现对焦和防抖各部件的合理配置。
在本申请的一具体示例中,如图8至图11A所示,防抖导电部243包括导电向下延伸部和导电横向延伸部(图中未示出),导电横向延伸部与防抖线圈2421导通,导电向下延伸部与感光芯片31的线路板导通,防抖导电部243构成防抖电路的一部分,连通防抖线路板2412与感光芯片31的线路板。在一些实施例中,防抖导电部243通过嵌件注塑成型,被设置在防抖可动载体2411内,导电横向延伸部部分裸露于防抖可动载体2411的上表面,与防抖线圈2421导通电连接,导电向下延伸部被设置在防抖可动载体2411的环形支撑臂内,下表面部分裸露,用于与感光芯片31的芯片线路板321电路连接。
在本申请的一具体示例中,如图8至图11A所示,防抖线圈2421与防抖磁石2422之间具有间隙,由防抖保持部244支撑保持,即防抖磁石2422与防抖线圈2421可由防抖保持部244支撑且相对运动。防抖磁石2422设置在基座21,防抖线圈2421设置于防抖可动载体2411,基座21与防抖可动载体2411之间具有间隙,防抖可动载体2411通过防抖保持部244连接于基座21,使得防抖可动载体2411可相对于基座21沿垂直于光轴水平移动。进一步的,防抖保持部244包括防抖磁吸构件2441和防抖支持构件2442。其中,防抖磁吸构件2441被设置在防抖可动载体2411,与防抖磁石2422的位置对应,以使得防抖磁吸构件2441与防抖磁石2422之间产生平行于光轴的磁吸力,使得防抖可动载体2411在移动后能够回复到初始位置。
在本申请的一个实施例中,防抖磁吸构件2441设置在防抖可动载体2411,与防抖磁石2422的位置对应。防抖磁吸构件2441可以为与防抖磁石2422产生磁吸力的构件,例如铁片等,与防抖磁石2422相互吸引。在一些实施例中,防抖磁吸构件2441可以通过嵌件注塑工艺一体成型于防抖可动载体2411。当然,在本申请另一具体示例中,防抖磁吸构件2441也可以通过粘接、焊接等方式固定于防抖可动载体2411,本申请对此不做限制。

在本申请的一个实施例中,如图7和图8所示,防抖可动载体2411上设置有滚珠槽24421,自防抖可动载体2411向上延伸形成,滚珠槽24421设置在防抖可动载体2411上的防抖线圈2421的外侧,滚珠槽24421用于容置防抖滚珠24422。滚珠槽24421的数量可以为四个,分别对称设置在防抖可动载体2411的上表面,可以设置在防抖可动载体2411上表面的四个角。基座21下表面向下延伸形成有与滚珠槽24421对应的凸台。防抖滚珠24422设置在滚珠槽24421内,在滚珠槽24421内运动。其中,防抖滚珠24422被容纳在滚珠槽24421内,防抖滚珠24422的一端接触滚珠槽24421,另一端接触基座21的下表面的凸台。滚珠槽24421的高度低于防抖滚珠24422的直径,使得防抖滚珠24422的部分裸露于滚珠槽24421。由于防抖滚珠24422支撑作用,通过防抖滚珠24422将防抖可动载体2411可动地连接于基座21,并使得两者之间保持有间隙。基座21凸台的设置,使得防抖滚珠24422在实现支撑保持防抖可动载体2411与基座21之间的间隙的同时,使得防抖滚珠24422以及滚珠槽24421的尺寸减小。在另一些实施例中,滚珠槽24421也可以设置在基座21。
防抖磁吸构件2441与防抖磁石2422的磁吸作用力,一方面,用于驱动防抖可动载体2411进行复位,另一方面,将防抖滚珠24422处于被夹持状态,防抖滚珠24422被始终夹持在防抖可动载体2411与基座21之间,避免防抖滚珠24422脱落。
在本申请的一个实施例中,如图10A所示,芯片防抖部分24还包括一防抖感测部245,防抖感测部245包括防抖位置感测元件2451以及防抖位置感应磁石2452,防抖位置感测元件2451包括X方向感测元件和Y方向感测元件,防抖位置感测元件2451和防抖位置感应磁石2452相对设置。防抖位置感测元件2451被设置在防抖可动载体2411,防抖位置感应磁石2452被设置在基座21上,当防抖可动载体2411移动时,防抖位置感测元件2451和防抖位置感应磁石2452的相对位置发生变化,根据防抖位置感测元件2451感测到的防抖位置感应磁石2452的磁场强弱,确定防抖可动载体2411的位置,进而调整防抖线圈2421的电流使得防抖可动载体2411移动到需要的位置。在一些实施例中,防抖位置感应磁石2452与防抖磁石2422共用,以减少结构件。在一些实施例中,防抖位置感测元件2451可以为为霍尔元件、驱动IC或TMR。
参照图11A至图13,摄像模组1还包括一感光组件30,该光学镜头10被设置于感光组件30的感光路径上,这样,感光组件30可以接收光学镜头10汇聚的光线以进行成像,在一个具体示例中,光学镜头10被固定于驱动装置20的对焦可动部231,感光组件30被固定于驱动装置20的防抖可动部241,从而光学镜头10被保持于感光组件30的感光路径上。驱动装置20的镜头对焦部分23包括被可移动地设置于 基座21的物侧的对焦可动部231和被设置于对焦可动部231和基座31之间的对焦驱动部232,对焦驱动部232适于驱动对焦可动部231相对基座21移动,该驱动装置20适于驱动光学镜头10沿光学镜头10的光轴移动;驱动装置20的镜头防抖部分24包括防抖可动部241和防抖驱动部242,防抖可动部241被可移动地设置于基座21的像侧,防抖可动部241包括被防抖可动载体2411,防抖驱动部242被设置于防抖可动载体2411和基座21之间,其中芯片防抖驱动部242包括相对设置的防抖磁石2422和防抖线圈2421,防抖磁石2422被设置在基座21上,防抖线圈2421被设置在防抖可动载体2411上,该驱动装置20适于驱动感光组件30在垂直于光轴的平面内移动。
如图11A至图13所示,感光组件30包括一线路板组件32以及电连接于该线路板组件32的一感光芯片31和电子元件34,该感光芯片31用于接收光学镜头10采集的外界光线成像并通过线路板组件32与外部移动电子设备电连接。在本申请的一个实施例中,该电子元件34可以是电阻、电容等无源电子器件和驱动芯片、存储芯片等有源电子器件中的一种或者多种。

该线路板组件32包括一芯片线路板321和一连接线路板322,芯片线路板321与连接线路板322电连接,感光芯片31电连接于芯片线路板321,从而感光芯片31适于通过连接线路板322与外部移动电子设备电连接。具体地,感光芯片31被固定于芯片线路板321,滤光元件支架332被固定于芯片线路板321,电子元件34被固定于芯片线路板321并电连接于芯片线路板321。进一步地,芯片线路板321被固定于防抖可动部241的防抖可动载体2411,防抖导电部243与芯片线路板321电导通。

在本申请的另一个实施例中,如图12A和图12B所示,芯片线路板321具有一通孔,感光芯片31被容置于该通孔中,从而降低感光组件30整体的高度。具体地,芯片线路板321固定于内线路板3221的正面,通过该通孔,芯片线路板321与内线路板3221形成一芯片容纳腔,感光芯片31被容置于容纳腔中并固定于内线路板3221,感光芯片31进一步直接与芯片线路板321电连接,在其他实施方式中,感光芯片31也可以直接与内线路板3221电连接。在本实施例中,电子元件34被固定并电连接于芯片线路板321,滤光元件支架332被固定于芯片线路板321,这样,内线路板3221的尺寸可以被设计的较小,在本申请的其他实施例中,电子元件34也可以被固定于内线路板3221且容置于芯片线路板321的通孔中,或者,部分电子元件34被固定于内线路板3221,部分电子元件34倍固定于芯片线路板321。
继续参照图13,柔性导通机构3222电连接内线路板3221和外线路板3223,柔性导通机构3222易于形变,当内线路板3221相对外线路板3223移动时,内线路板3221受到的阻力较小,从而驱动装置20驱动固定有感光芯片31的芯片线路板321移动时,与芯片线路板321相固定的内线路板3221移动产生的阻力影响较小,进而驱动装置20的驱动力可以被设计的较小,从而驱动装置20的尺寸得以被降低。
在本申请的一个实施例中,从俯视方向看,外线路板3223和内线路板3221均具有矩形的周侧形状,其中外线路板3223具有一通孔,该通孔适于为矩形通孔,该通孔的尺寸大于内线路板3221的尺寸,从而内线路板3221和柔性导通机构3222被设置于该通孔中。而由于外线路板3223呈环状,设置导通电路的面积被减小,在本申请的一个具体示例中,为使线路板组件32整体尺寸保持较小,使外线路板3223的厚度增加,外线路板3223的厚度大于内线路板3221的厚度,从而外线路板3223中可以设置更多层的导通电路,进而在较窄的宽度下可以满足电导线的设置需求。外线路板3223的厚度大于内线路板3221的厚度,使得内线路板3221的底面的位置可以高于外线路板3223的底面。
该连接线路板322进一步包括一连接带3224,连接带3224被固定于外线路板3223的一侧并与外线路板3223电连接,借由该连接带3224,线路板组件32与外部移动电子设备电连接。
该柔性导通机构3222包括至少二柔性导通臂32221,至少二柔性导通臂32221在内线路板3221和外线路板3223之间在X方向和Y方向延伸并连接内线路板3221和外线路板3223,柔性导通臂32221上可以通过设置电导线的方式实现电导通功能电连接内线路板3221和外线路板3223。在本申请的一个实施例中,至少二柔性导通臂32221包括两个在内线路板3221相对侧设置的柔性导通臂32221,具体地,该柔性导通机构3222包括四个柔性导通臂32221,四个柔性导通臂32221分别位于内线路板3221的四侧并连接内线路板3221和外线路板3223,从而使外线路板3223通过柔性导通机构3222提供给内线路板3221的支持较为稳定且对称。当然,在本申请中,该柔性导通机构3222还可以包括两个、三个或者更多个柔性导通臂32221,本申请并不为此所限。
在本申请的一个实施例中,柔性导通臂32221可以包括一个或者多个柔性电连接件,当柔性电连接件的数量被设计的较多时,可以提供内线路板3221和外线路板3223之间更多的导通电路,具体地,柔性导通臂32221中柔性电连接件的数量根据感光芯片31的电路需求决定。
继续参照图11A和图12A,该外线路板3223被固定于外壳22,例如外线路板3223被固定于外壳22的外壳主体221或者外壳底板222,从而外线路板3223在摄像模组1中属于相对固定的部分,而被直接或者间接与防抖可动载体2411相固定的内线路板3221则属于相对可动的部分,由于内线路板3221与外线路板3223之间通过易于形变的柔性导通机构3222连接并电导通,内线路板3221移动的阻力较低。外壳22具有一容纳腔以容纳基座21和芯片防抖部分24,基座21被固定于外壳22,外线路板3223通过固定于外壳22间接地被固定于基座21,在本申请的其他实施例中,外线路板3223也可以直接固定于基座21,即,外线路板3223被固定于基座21包括了上述间接和直接两种情形。
在本申请的一个实施例中,该感光组件30还包括一底座35,该外线路板3223被固定于底座35,该底座35被固定于外壳22,从而底座35和外壳22形成一相对封闭的空间,防止灰尘等脏污从内线路板3221和外线路板3223之间的间隙中进入感光组件30。在一个具体示例中,内线路板3221与底座35之间具有空气间隙,内线路板3221高于外线路板3223,也即,内线路板3221的底面与底座35的顶面之间的距离大于内线路板3221的底面与底座35的顶面之间的距离,这样,当内线路板3221移动时,内线路板3221与底座35之间不会发生摩擦,减小了移动的阻力。在本示例中,柔性导通臂32221呈倾斜的连接内线路板3221和外线路板3223,其中柔性导通臂32221连接内线路板3221的一端高于连接外线路板3223的一端。
换言之,在本申请中,外线路板3223可以被固定于驱动装置20的相对固定的部分(例如外壳22、底座35、基座21等部件为驱动装置20的相对固定的部分),内线路板3221被固定于防抖可动载体2411(内线路板3221可以被直接的固定于防抖可动载体2411,也可以通过固定于芯片线路板321被间接的固定于防抖可动载体2411),芯片防抖可动载体2411被防抖保持部244保持于基座21,从而内线路板3221可以被维持在高于外线路板3223的位置,也即,内线路板3221的底面可以高于外线路板3223的底面,使内线路板3221在移动过程中不易受到摩擦阻力的影响。
防抖保持部244包括被设置于防抖可动载体2411的防抖磁吸构件2441和被设置于基座21与防抖可动载体2411之间的防抖支持构件2442,防抖磁吸构件2441与防抖磁石2422之间产生的磁吸力使防抖可动载体2411被吸附向基座21并使防抖支持构件2442被防抖可动载体2411和基座21夹持,同时,借由防抖磁吸构件2441与防抖磁石2422之间的磁吸作用,内线路板3221的高度得以被维持。
在本申请的一个实施例中,线路板组件32还包括被固定于内线路板3221背面的内补强板323和被固定于外线路板3223背面的外补强板324,用以增强连接线路板322的结构强度,内补强板323和外补强板324的材料可以为不锈钢,其中,外补强板324呈环状结构,其形状与外线路板3223相近。在本实施例中,该内补强板323与底座35之间具有空气间隙,内补强板323的底面与底座35的顶面之间的距离大于外补强板324的底面与底座35的顶面之间的距离,这样,当内线路板3221移动时,内补强板323与底座35之间不会发生摩擦,减小了移动的阻力。在该实施例中,内线路板3221的高度也可以高于外线路板3223的高度。
以上描述了本申请的基本原理、主要特征和本申请的优点。本行业的技术人员应该了解,本申请不受上述实施例的限制,上述实施例和说明书中描述的只是本申请的原理,在不脱离本申请精神和范围的前提下本申请还会有各种变化和改进,这些变化和改进都落入要求保护的本申请的范围内。本申请要求的保护范围由所附的权利要求书及其等同物界定。
