镜头马达、摄像模组以及电子设备
本申请要求在2022年11月18日提交中国国家知识产权局、申请号为202211448545.X的中国专利申请的优先权,发明名称为“镜头马达、摄像模组以及电子设备”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
本申请涉及摄像技术领域,特别涉及一种镜头马达、摄像模组以及电子设备。
背景技术
随着智能手机的普及和发展,手机拍照成为人们普遍使用的拍摄方式,并且,同时具有可光学防抖功能以及自动对焦功能的手机越来越得到用户的喜爱。传统的摄像模组包括模组电路板、防抖驱动芯片以及对焦驱动芯片。由于防抖驱动芯片与对焦驱动芯片均做在模组电路板上,使得防抖驱动芯片与对焦驱动芯片在生产过程中无法在马达厂进行标定数据的烧录,而需要在后续的模组厂中进行标定工作,从而使得驱动芯片的标定流程较为复杂,摄像模组的整体生产效率较低。
发明内容
本申请实施例提供一种镜头马达、包括所述镜头马达的摄像模组、以及包括所述摄像模组的电子设备,旨在获得一种工艺流程较简捷,且生产效率较高的镜头马达以及摄像模组。
第一方面,提供了一种镜头马达。镜头马达包括定子、对焦支架、防抖支架、对焦驱动机构、防抖驱动机构以及驱动芯片。对焦支架活动连接定子,防抖支架活动连接对焦支架,且位于对焦支架的内侧,防抖支架用于安装镜头。驱动芯片用于控制对焦驱动机构,以使对焦驱动机构驱动对焦支架带动防抖支架相对定子沿第一方向移动,驱动芯片还用于控制防抖驱动机构,以使防抖驱动机构驱动防抖支架相对对焦支架沿第二方向和第三方向移动,第一方向为镜头的光轴方向,第二方向、第三方向与第一方向不同。
可以理解的是,传统的镜头马达的驱动芯片通常设置于镜头马达外部的模组电路板上。这使得摄像模组在生产过程中无法在马达厂对驱动芯片进行相关标定数据的烧录,而需要在模组厂对驱动芯片进行相关的标定工作。而本申请中的驱动芯片内置于镜头马达,使得摄像模组在生产过程中,在马达厂时即可将相关的标定数据直接烧录于镜头马达内的驱动芯片,节省了后续在模组厂的标定流程,提高生产效率。同时,当镜头马达因可靠性或者模组制程等因素导致特性变异时,有利于对镜头马达进行特性变异后的数据比对。
另外,相较于需要多个驱动芯片分别控制防抖驱动机构与对焦驱动机构的镜头马达,本申请中的镜头马达通过一个驱动芯片同时控制防抖驱动机构和对焦驱动机构。当防抖驱动机构与对焦驱动机构中的其中一者需要获取另一者的位置信息时,驱动芯片可以通过进行对应的算法补偿,以获取相应的位置信息。这样,防抖驱动机构与对焦驱动机构之间的信息交互更加快捷,驱动芯片无需进行额外的数据烧录,有利于提高驱动芯片获取位置信息的效率,提高镜头马达的响应速度。
此外,本申请的镜头马达为同时具有防抖功能和对焦功能的一体式马达,且驱动芯片内置于镜头马达。这样,通过镜头马达内部的驱动芯片即可同时控制对焦支架带动防抖支架相对定子沿第一方向移动实现对焦功能,以及控制防抖支架相对对焦支架沿第二方向和第三方向移动实现防抖功能。相较于对焦支架与防抖支架分开设置的分体式镜头马达,本申请的镜头马达体积更小,有利于实现镜头马达的小型化设置,有利于节省电子设备的内部空间。
一种可能的实现方式中,定子包括底座,对焦支架活动连接底座,底座设有第一避让孔,第一避让孔连通底座的外周侧和内周侧。镜头马达还包括电路板,电路板固定在底座的外周侧,驱动芯片固定在电路板上,且电连接电路板,驱动芯片的至少部分位于第一避让孔内。这样,通过利用底座的厚度尺寸将驱动芯片设于第一避让孔内,可以有效减少驱动芯片在镜头马达内部的占用空间,有利于提高镜头马达的空间利用率。
一种可能的实现方式中,防抖驱动机构包括防抖线圈与防抖磁性件,防抖线圈固定在电路板上,且电连接电路板,防抖磁性件固定在防抖支架上,防抖线圈与防抖磁性件相对设置。防抖线圈电连接驱动芯片,驱动芯片还用于控制防抖线圈,以通过防抖线圈和防抖磁性件的配合来驱动防抖支架相对对焦支架沿第二方向移动,或者驱动防抖支架相对对焦支架沿第三方向移动。这样,驱动芯片可以控制防抖线圈,通过防抖线圈与防抖磁性件之间的配合所产生的驱动力来驱动防抖支架移动,以实现镜头马达的防抖功能。
一种可能的实现方式中,防抖线圈通过第一避让孔朝向防抖磁性件。这样,防抖线圈与驱动芯片可以 位于电路板的同一侧。同时,防抖线圈与驱动芯片均位于第一避让孔内,可以有效减少防抖线圈以及驱动芯片在镜头马达内部的占用空间,有利于提高镜头马达的空间利用率。
一种可能的实现方式中,底座设有第一避让槽,第一避让槽贯穿底座的底部。对焦支架设有第二避让槽,第二避让槽连通防抖支架的底部空间以及第一避让槽。第一避让槽、第二避让槽和防抖支架的底部空间构成安装空间,安装空间用来容置棱镜的一部分。
可以理解的是,本申请的镜头马达通过设置安装空间,并将棱镜的至少部分可以位于安装空间内,使得镜头马达可以相对棱镜下沉,以降低镜头马达的高度,从而实现摄像模组的整体降高,有利于实现摄像模组的薄型化设置,同时,摄像模组的整体结构更加紧凑,有利于节省电子设备的内部空间。
一种可能的实现方式中,防抖支架包括第一支架与第二支架,第一支架位于对焦支架与第二支架的底部之间,第一支架活动连接对焦支架,第二支架活动连接第一支架。驱动芯片用于控制防抖驱动机构,以使防抖驱动机构驱动第一支架带动第二支架相对对焦支架沿第二方向移动,驱动芯片还用于控制防抖驱动机构,以使防抖驱动机构驱动第二支架相对第一支架沿第三方向移动。这样,通过将第一支架与第二支架堆叠设置,再分别控制第一支架相对对焦支架沿第二方向移动,以及第二支架相对第一支架沿第三方向移动,即可实现防抖支架带动镜头相对对焦支架沿第二方向移动和沿第三方向移动,实现防抖功能。
一种可能的实现方式中,防抖线圈包括第一线圈与第二线圈,防抖磁性件包括第一磁性件与第二磁性件,第一线圈与第一磁性件相对设置,第二线圈与第二磁性件相对设置。驱动芯片用于控制第一线圈,以通过第一线圈与第一磁性件的配合来驱动第一支架相对对焦支架沿第二方向移动,驱动芯片还用于控制第二线圈,以通过第二线圈和第二磁性件的配合来驱动第二支架相对第一支架沿第三方向移动。这样,驱动芯片可以分别控制第一线圈与第二线圈,通过第一线圈与第一磁性件之间的配合所产生的驱动力来驱动第一支架移动,以及通过第二线圈与第二磁性件之间的配合所产生的驱动力来驱动第二支架移动,从而实现镜头马达的防抖功能。
一种可能的实现方式中,第一线圈包括第一子线圈和第二子线圈,第一磁性件包括第一子磁性件以及第二子磁性件,第一子磁性件与第二子磁性件位于第一子线圈和第二子线圈之间,第一子线圈与第一子磁性件相对设置,第二子线圈与第二子磁性件相对设置。这样,通过将第一子线圈与第一子磁性件配合产生的驱动力,与第二子线圈与第二子磁性件配合产生的驱动力叠加,从而可以提高防抖驱动机构对第一支架的驱动力,有利于提高第一支架的移动速度,提高镜头马达在第二方向上的防抖响应速度。
一种可能的实现方式中,第一支架通过滚珠活动连接对焦支架,和/或,第二支架通过滚珠活动连接第一支架。可以理解的是,由于滚珠的摩擦系数较小,使得第一支架与对焦支架之间的摩擦力较小,第二支架与第一支架之间的摩擦力较小,从而可以减小防抖驱动机构所需要的驱动力,有利于减少镜头马达的能源损耗,提高电子设备的续航时间。
一种可能的实现方式中,第一支架包括第一支部和第二支部,第二支部连接第一支部,第二支部与第一支部之间的角度小于180°。对焦支架的底部包括第一部分和第二部分,第二部分堆叠于第一部分,第二部分的一部分与第一支部相对设置,第二部分的另一部分与第二支部相对设置。这样,第二部分可以相对第一部分抬升,第一支架可以相对第二部分下沉,从而减薄镜头马达的整体厚度,有利于实现镜头马达的薄型化设置。同时,第二部分相对第一部分抬升,使得第二部分的底部空间可以得到释放,有利于增大镜头马达内部的可利用空间。
一种可能的实现方式中,底座空间位于第二部分的底部。第一部分的内侧面朝向底部空间。这样,第二部分的底部空间也可以用于方式棱镜的至少部分,从而实现摄像模组的整体降高,有利于实现摄像模组的薄型化设置,同时,摄像模组的整体结构更加紧凑,有利于节省电子设备的内部空间。
一种可能的实现方式中,对焦支架通过滑轴活动连接定子。这样,由于滑轴的摩擦系数较大,使得对焦支架在镜头马达断电之后,仍可以通过自身与滑轴之间的摩擦力实现自锁,进而无需外部电源对镜头马达持续通电,有利于节省电源,提高电子设备的续航时间。同时,对焦支架移动时,较不容易产生偏斜,有利于保证镜头马达的对焦效果,提高摄像模组的成像质量。
一种可能的实现方式中,对焦驱动机构包括对焦线圈和对焦磁性件,对焦线圈固定在电路板上,且电连接电路板,对焦磁性件固定在对焦支架上,对焦线圈与对焦磁性件相对设置。对焦线圈电连接驱动芯片,驱动芯片还用于控制对焦线圈,以通过对焦线圈与对焦磁性件的配合来驱动对焦支架带动防抖支架相对定子沿第一方向移动。这样,驱动芯片可以控制对焦线圈,通过对焦线圈与对焦磁性件之间的配合所产生的驱动力来驱动对焦支架移动,以实现镜头马达的对焦功能。
一种可能的实现方式中,镜头马达还包括第一磁吸片,第一磁吸片固定于电路板,对焦线圈位于第一 磁吸片与对焦磁性件之间,对焦支架在第一磁吸片与对焦磁性件之间的作用力下挤压滑轴。这样,第一磁吸片可以吸附对焦磁性件,使得对焦支架可以挤压滑轴,使得对焦支架与滑轴可以紧密接触,从而可以有效避免对焦支架相对定子移动时发生倾翻。
一种可能的实现方式中,镜头马达还包括第一传感器,第一传感器固定于电路板,且电连接电路板,驱动芯片电连接第一传感器,第一传感器用于检测对焦支架的位置,驱动芯片还用于获取第一传感器的信息。这样,驱动芯片可以及时获取对焦支架的位置信息,有利于提高驱动芯片获取位置信息的效率,提高镜头马达的响应速度。
一种可能的实现方式中,镜头马达还包括盖板,盖板连接对焦支架,盖板位于防抖支架远离对焦支架的一侧。这样,可以有效避免电子设备发生翻转倾斜时,防抖支架从对焦支架中脱出,有利于提高镜头马达的结构可靠性。
第二方面,提供了一种摄像模组。摄像模组包括镜头、棱镜、感光芯片、以及上述的镜头马达,镜头安装于防抖支架,棱镜位于镜头的出光侧,感光芯片位于棱镜的出光侧。
可以理解的是,传统的镜头马达的驱动芯片通常设置于镜头马达外部的模组电路板上。这使得摄像模组在生产过程中无法在马达厂对驱动芯片进行相关标定数据的烧录,而需要在模组厂对驱动芯片进行相关的标定工作。而本申请中的驱动芯片内置于镜头马达,使得摄像模组在生产过程中,在马达厂时即可将相关的标定数据直接烧录于镜头马达内的驱动芯片,节省了后续在模组厂的标定流程,提高生产效率。同时,当镜头马达因可靠性或者模组制程等因素导致特性变异时,有利于对镜头马达进行特性变异后的数据比对。
另外,相较于需要多个驱动芯片分别控制防抖驱动机构与对焦驱动机构的镜头马达,本申请中的镜头马达通过一个驱动芯片同时控制防抖驱动机构和对焦驱动机构。当防抖驱动机构与对焦驱动机构中的其中一者需要获取另一者的位置信息时,驱动芯片可以通过进行对应的算法补偿,以获取相应的位置信息。这样,防抖驱动机构与对焦驱动机构之间的信息交互更加快捷,驱动芯片无需进行额外的数据烧录,有利于提高驱动芯片获取位置信息的效率,提高镜头马达的响应速度。
此外,本申请的镜头马达为同时具有防抖功能和对焦功能的一体式马达,且驱动芯片内置于镜头马达。这样,通过镜头马达内部的驱动芯片即可同时控制对焦支架带动防抖支架相对定子沿第一方向移动实现对焦功能,以及控制防抖支架相对对焦支架沿第二方向和第三方向移动实现防抖功能。相较于对焦支架与防抖支架分开设置的分体式镜头马达,本申请的镜头马达体积更小,有利于实现镜头马达的小型化设置,有利于节省电子设备的内部空间。
一种可能的实现方式中,棱镜包括依次连接的第一面、第一斜面、第二面以及第二斜面,镜头与感光芯片均位于第一面背向第二面的一侧,第一面包括第一区域与第二区域,镜头与第一区域相对设置,感光芯片与第二区域相对设置。其中,环境光线经过镜头后,由第一面的第一区域进入棱镜,在棱镜内部发生多次反射后,由第一面的第二区域射出,感光芯片采集穿过棱镜的环境光线。这样,相较于镜头与感光芯片位于棱镜的不同侧的摄像模组,本申请的摄像模组中镜头与感光芯片位于棱镜的同一侧,有利于降低摄像模组的整体高度,实现摄像模组的薄型化设置。
第三方面,提供了一种电子设备。电子设备包括设备壳体以及上述的摄像模组,摄像模组设于设备壳体。可以理解的是,本申请的电子设备中的镜头马达为同时具有防抖功能和对焦功能的一体式马达,且驱动芯片内置于镜头马达。这样,通过镜头马达内部的驱动芯片即可同时控制对焦支架带动防抖支架相对定子沿第一方向移动实现对焦功能,以及控制防抖支架相对对焦支架沿第二方向和第三方向移动实现防抖功能。相较于对焦支架与防抖支架分开设置的分体式镜头马达,本申请的镜头马达体积更小,有利于实现镜头马达的小型化设置,有利于节省电子设备的内部空间。

本申请实施例提供一种终端,所述终端包括且不限于手机、平板电脑、多媒体播放器、电子书阅读器、笔记本电脑、车载设备或可穿戴设备等具有显示功能的电子设备。本申请以所述终端是手机为例进行具体说明。
图1是本申请实施例提供的一种电子设备1000的结构示意图。图2a是图1所示的电子设备1000在A-A线上的一种实施方式中的部分剖视图。
如图1和图2a所示,电子设备1000可以为手机、平板电脑(tablet personal computer)、膝上型电脑(laptop computer)、个人数码助理(personal digital assistant,PDA)、照相机、个人计算机、笔记本电脑、车载设备、可穿戴设备、增强现实(augmented reality,AR)眼镜、AR头盔、虚拟现实(virtual reality,VR)眼镜或者VR头盔等具有摄像模组的设备。图1所示实施例的电子设备1000以手机为例进行阐述。
如图1所示,电子设备1000可以包括摄像模组100、设备壳体200以及屏幕300。其中,摄像模组100可以为后置摄像模组,也可以为前置摄像模组。需要说明的是,图1以及下文相关附图仅示意性的示出了电子设备1000包括的一些部件,这些部件的实际形状、实际大小、实际位置和实际构造不受图1以及下文各附图限定。此外,当电子设备1000为一些其他形态的设备时,电子设备1000也可以不包括屏幕300。
为了便于描述,定义电子设备1000的宽度方向为X轴。电子设备1000的长度方向为Y轴。电子设备1000的厚度方向为Z轴。可以理解的是,电子设备1000的坐标系设置可以根据具体实际需要灵活设置。
在本实施方式中,设备壳体200可以包括边框201以及后盖202。后盖202固定于边框201。示例性的,后盖202可以通过粘胶固定连接于边框201。后盖202也可以与边框201为一体成型结构,即后盖202与边框201为一个整体结构。
另外,屏幕300可以位于边框201远离后盖202的一侧。此时,屏幕与后盖202分别位于边框201的两侧。屏幕300、边框201与后盖202共同围出电子设备1000的内部。电子设备1000的内部可以用于放置电子设备1000的器件,例如电池、受话器或者麦克风等。其中,屏幕300可以为平面屏,也可以为曲面屏。
示例性地,摄像模组100可以位于电子设备1000的内部。摄像模组100可以固定于屏幕300朝向后盖202的一侧。后盖202可以开设有透光孔203。透光孔203的形状不仅限于附图1所示意的圆形。透光孔203将电子设备1000的内部连通至电子设备1000的外部。电子设备1000外部的光线可以通过透光孔203进入电子设备1000的内部。摄像模组100可以采集进入电子设备1000内部的环境光线。

图2b是图1所示的摄像模组100的一种实施方式的结构示意图。图3是图2a所示的摄像模组100的分解示意图。
如图2a和图2b所示,摄像模组100可以包括镜头马达1、镜头2、棱镜4、模组底座5、电路模块6以及模组外壳7。其中,镜头马达1与镜头2可以构成镜头组件400。镜头马达1可以围出安装孔3。镜头2可以安装在安装孔3内。在其他实施方式中,镜头2与镜头马达1的安装方式不做具体限定。
可以理解的是,镜头马达1可以通过控制镜头2沿镜头2的光轴方向(在本实施方式中,镜头2的光轴方向为Z轴方向)的移动,以用于实现自动对焦(auto focus,AF)。
另外,镜头马达1还可以通过控制镜头2沿垂直于光轴的平面(在本实施方式中,垂直于光轴的平面为X-Y平面)运动。这样,当摄像模组100采集环境光线时,若电子设备1000因外力作用而在X-Y平面产生抖动,则可以通过镜头马达1控制镜头2在X-Y平面上的移动,抵消镜头2在X-Y平面产生的抖动行程,以避免或者减少镜头2因抖动而导致的位置偏移。换言之,本申请的摄像模组100可以通过镜头马达1控制镜头2在X-Y平面上的移动,从而实现摄像模组100的光学图像防抖(optical image stabilization,OIS),提高摄像模组100的成像质量。
上文具体介绍了电子设备1000以及摄像模组100的结构,下文将结合相关附图具体介绍摄像模组100中的镜头马达1。

应理解,在本实施方式中,镜头马达1的宽度方向也即电子设备1000的宽度方向,为X轴方向。镜头马达1的长度方向也即电子设备1000的长度方向,为Y轴方向。镜头马达1的厚度方向也即电子设备1000的厚度方向,为Z轴方向。其中,Z轴方向也即第一方向。X轴方向也即第二方向。Y轴方向也即第三方向。在其他实施方式中,镜头马达1的坐标系设置可以根据具体实际需要灵活设置。
图6是图5所示的底座20与滑轴90的结构示意图。

可以理解的是,本实施方式中的第二支架522可以通过滚珠529活动连接第一支架521。第二支架522可以相对第一支架521沿Y轴方向移动。当第二支架522相对第一支架521沿Y轴的正方向移动时,第二收容槽5225b靠近第一安装槽5227的槽壁可以沿靠近第二支撑部5213的方向移动,直至该槽壁与第二支撑部5213抵接。当第二支架522相对第一支架521沿Y轴的负方向移动时,第一收容槽5225a靠近第一安装槽5227的槽壁可以沿靠近第一支撑部5211的方向移动,直至该槽壁与第一支撑部5211抵接。这样,通过第一收容槽5225a的槽壁与第一支撑部5211的配合,以及第二收容槽5225b的槽壁与第二支撑部5213的配合,可以避免第二支架522在移动过程中与第一支架521脱离,同时可以避免第二支架522与第一支架521之间的滚珠529脱出滚珠槽。
在其他实施方式中,还可以仅第一支架521通过滚珠529活动连接对焦支架511。或者,仅第二支架522通过滚珠529活动连接第一支架521。
图29是图13所示的动子50的结构示意图。
如图26和图29所示,盖板53可以盖合于对焦支架511。此时,盖板53可以位于防抖支架52a远离对焦支架511的一侧。防抖动子52可以位于对焦支架511与盖板53之间。示例性地,盖板53可以设有多个扣合槽531。对焦支架511可以设有多个扣合凸起5120。多个扣合槽531可以一一对应地与多个扣合凸起5120配合,以将盖板53固定于对焦支架511。
可以理解的是,本实施方式中的第一支架521可以通过滚珠529活动连接对焦支架511,并带动第二支架522相对对焦支架511沿X轴方向移动,从而使得防抖动子52可以相对对焦动子51沿X轴方向移动。当第一支架521相对对焦支架511沿X轴的正方向移动时,第一支撑部5211可以沿朝向限位块5110的方向移动,直至第一支撑部5211与限位块5110抵接。第三支撑部5215可以沿朝向第一限位槽5112b的方向移动,直至第三支撑部5215与第二限位槽5112c的槽壁抵接。当滚动支架相对对焦支架511沿X轴的负方向移动时,第二支撑部5213可以沿靠近第二限位槽5112c的方向移动,直至第二支撑部5213与第一限位槽5112b的槽壁抵接。这样,通过第一支撑部5211与限位块5110的配合、第二支撑部5213与第一限位槽5112b的配合以及第三支撑部5215与第二限位槽5112c的配合,可以避免第一支架521与对焦支架511之间的滚珠529脱出滚珠槽。
另外,本实施方式通过第一子磁性件5231与其中一个第二磁吸片514之间的吸附力,以及第二磁性件524与另一个第二磁吸片514之间的吸附力,使得防抖动子52可以在吸附力的作用下沿Z轴方向挤压对焦动子51的对焦支架511。此时,多个滚珠529可以一一对应地紧密贴合多个滚珠槽的槽壁。这样,可以有效避免防抖动子52在X-Y平面中移动时产生倾翻。
此外,本实施方式通过设置盖板53盖合于对焦支架511,使得对焦动子51可以完全包裹防抖动子52。这样,可以有效避免电子设备1000发生翻转倾斜时,镜头马达1中的防抖动子52从对焦动子51中脱出。
图30是图5所示的镜头马达1的部分结构示意图。图31是图4所示的镜头马达1在E-E线上的一种实施方式的剖视图。图32是图4所示的镜头马达1在F-F线上的一种实施方式的剖视图。
如图30至图32所示,动子50可以安装于底座20的容置空间23。对焦支架511的第一滑槽5113a可以与第一滑轴91配合。对焦支架511的第二滑槽5113b可以与第二滑轴92配合。此时,对焦支架511可以相对底座20沿第一滑轴91的轴向方向移动。在本实施方式中,第一滑轴91的轴向方向为Z轴方向。换言之,动子50可以相对底座20沿Z轴方向移动。
示例性地,第一磁吸片40可以吸附对焦磁性件512。此时,对焦支架511可以在第一磁吸片40与对焦磁性件512之间的吸附力的作用下沿Y轴方向挤压第一滑轴91与第二滑轴92,使得第一滑轴91可以紧密贴合第一滑槽5113a,以及第二滑轴92可以紧密贴合第二滑槽5113b。这样,可以有效避免动子50在相对底座20沿Z轴方向移动时产生倾翻。
在一些实施方式中,子磁吸片41(请参阅图8)也可以吸附对焦磁性件512。这样,子磁吸片41可以与第一磁吸片40一同吸附对焦磁性件512,从而可以增强第一磁吸片40对对焦磁性件512的吸附力。另外,子磁吸片41还可以用于平衡第一磁吸片40产生的Z向干扰力。
在其他实施方式中,滑轴90还可以替换为多个滚珠。
如图5、图31和图32所示,第一传感器81可以用于检测当对焦磁性件512处于不同位置下的磁场强度,以检测对焦支架511的位置。第二传感器82可以用于检测第一子磁性件5231处于不同位置下的磁场强度,以检测防抖支架52a在X轴方向上的位置。第三传感器83可以用于检测当第二磁性件524处于不同位置下的磁场强度,以检测防抖支架52a在Y轴方向上的位置。驱动芯片60可以同时获取第一传感器81、第二传感器82以及第三传感器83的信息。
图33是图4所示的镜头马达1在D-D线上的一种实施方式的剖视图。图34是图3所示的镜头马达1与镜头2的结构示意图。
如图31和图33所示,底座20的第一避让槽211可以连通对焦支架511的第二避让槽50a以及第二部分5112的底部空间5112a(图14从另一角度示意出了第二避让槽50a,图15从另一角度示意出了底部空间5112a)。此时,第一避让槽211、第二避让槽50a以及第二部分5112的底部空间5112a可以共同构成镜头马达1的安装空间1a。安装空间1a可以用于收容摄像模组100的其他镜片或者棱镜的至少部分。应理解,图33通过虚线示意出了第一避让槽211、第二避让槽50a以及第二部分5112的底部空间5112a。
如图32至图34所示,对焦线圈71可以与对焦磁性件512相对设置。此时,对焦线圈71与对焦磁性件512可以共同构成对焦动子51的对焦驱动机构51a。第一子线圈7211可以与第一子磁性件5231相对设置。第二线圈722可以与第二磁性件524相对设置。第二子线圈7212可以与第二子磁性件5232相对设置。 此时,第一子线圈7211、第二线圈722、第二子线圈7212、第一子磁性件5231、第二磁性件524以及第二子磁性件5232可以共同构成防抖动子52的防抖驱动机构52b。
当对焦线圈71施加有信号时,对焦磁性件512可以与对焦线圈71配合,从而驱动对焦支架511并带动第一支架521及第二支架522(也即防抖支架52a)一同相对底座20沿Z轴方向移动。换言之,镜头2可以在动子50的作用下,相对底座20沿Z轴方向移动,实现自动对焦功能。
当第一子线圈7211与第二子线圈7212施加有信号时,第一子磁性件5231可以与第一子线圈7211配合,第二子磁性件5232可以与第二子线圈7212配合,从而驱动第一支架521并带动第二支架522相对对焦支架511沿X轴方向移动,也即第二支架522相对底座20沿X轴方向移动。当第二线圈722施加有信号时,第二磁性件524可以与第二线圈722配合,从而驱动第二支架522相对第一支架521沿Y轴方向移动,也即第二支架522相对底座20沿Y轴方向移动。换言之,镜头2可以在动子50的作用下,相对底座20在X-Y平面上移动,实现光学防抖功能。
其中,对焦磁性件512与对焦线圈71配合产生的驱动力为动子50的Z向驱动力。Z向驱动力可以大于动子50及镜头2的整体重力、对焦支架511与第一滑轴91以及第二滑轴92之间的摩擦力、子磁吸片41(请参阅图8)与对焦磁性件512之间的吸附力以及第一磁吸片40与对焦磁性件512之间的吸附力之和。第一子磁性件5231与第一子线圈7211配合产生的驱动力以及第二子磁性件5232与第二子线圈7212配合产生的驱动力之和为动子50的X向驱动力。X向驱动力可以大于防抖动子52及镜头2的整体重力以及第一支架521与对焦支架511之间的摩擦力之和。第二磁性件524与第二线圈722配合产生的驱动力为动子50的Y向驱动力。Y向驱动力可以大于第二支架522及镜头2的整体重力以及第二支架522与第一支架521之间的摩擦力之和。
可以理解的是,本实施方式中的镜头马达1同时包括驱动芯片60、防抖动子52和对焦动子51。其中,防抖支架52a可以位于对焦支架511的收容空间511d内。镜头2可以安装于防抖支架52a。驱动芯片60可以通过控制对焦驱动机构51a,以使对焦驱动机构51a驱动对焦支架511带动防抖支架52a相对底座20沿Z轴方向移动。驱动芯片60还可以通过控制防抖驱动机构52b,以使第一支架521带动第二支架522相对底座20沿X轴方向移动,以及第二支架522相对底座20沿Y轴方向移动。这样,当镜头2安装于第二支架522的第二通孔5224时,通过控制第二支架522相对底座20在Z轴方向移动以及在X-Y平面上的移动,从而可以带动镜头2相对底座20在Z轴方向移动以及在X-Y平面上的移动。
换言之,本实施方式的镜头马达1为同时具有防抖功能和对焦功能的一体式马达,驱动芯片60内置于镜头马达1内部。这样,通过镜头马达1内部的驱动芯片即可同时控制第二支架522相对底座20沿Z轴方向移动实现对焦功能,以及控制第二支架522相对底座20在X-Y平面移动实现防抖功能。相较于防抖动子52与对焦动子51分开设置的分体式镜头马达1,本实施方式的镜头马达1体积更小,有利于减小摄像模组100的堆叠尺寸,简化工艺流程,同时还有利于节省电子设备1000的内部空间。同时,相较于需要多个驱动芯片60分别控制防抖动子52与对焦动子51的镜头马达1,本实施方式中的镜头马达1通过一个驱动芯片60同时控制防抖动子52的防抖驱动机构52b和对焦动子51的对焦驱动机构51a。当防抖动子52与对焦动子51中的其中一者需要获取另一者的位置信息时,驱动芯片60可以通过进行对应的算法补偿,以获取相应的位置信息。这样,防抖动子52与对焦动子51之间的信息交互更加快捷,驱动芯片60无需进行额外的数据烧录,有利于提高驱动芯片60获取位置信息的效率,提高镜头马达1的响应速度。
另外,传统的镜头马达1的驱动芯片60通常设置于镜头马达1的外部的电路板上。这使得摄像模组100在生产过程中无法在马达厂对驱动芯片60进行相关标定数据(例如位置传感器80的校正数据、线性度标定数据以及对焦动子51对防抖动子52的串扰的标定数据等)的烧录,而需要在模组厂对驱动芯片60进行相关的标定工作。而本实施方式中的驱动芯片60内置于镜头马达1,使得摄像模组100在生产过程中,在马达厂时即可将相关的标定数据直接烧录于镜头马达1内的驱动芯片60,节省了后续在模组厂的标定流程,提高生产效率。同时,当镜头马达1因可靠性或者模组制程等因素导致特性变异时,有利于对镜头马达1进行特性变异后的数据比对。
其次,传统的对焦动子51通常通过滚珠529滑动连接于底座20,或者通过簧片连接于底座20。其中,滚珠式的对焦动子51由于滚珠529的摩擦系数较小,因此无法实现自锁。同时,对焦支架511相对底座20沿Z方向移动时,容易产生偏斜,产生X-Y平面的位移,影响对焦清晰度。簧片式的对焦动子51,由于簧片的抗震颤效果较差,因而容易影响电子设备1000的视频效果。而本实施方式中的对焦支架511通过滑轴90滑动连接底座20,为滑轴式对焦动子51。其中,滑轴90的摩擦系数较大,使得对焦动子51在断电之后仍可以通过自身与滑轴90之间的摩擦力实现自锁,从而无需外部电源对镜头马达1持续通电, 有利于节省电源,提高电子设备1000的续航时间。滑轴90的抗震颤效果较好,有利于保证电子设备1000的视频效果。同时,滑轴式的对焦动子51中的对焦支架511相对底座20沿Z轴方向移动时,较不容易产生偏斜,有利于保证镜头马达1的对焦效果,提高摄像模组100的成像质量。其中,镜头2的倾斜角度可以小于或者等于3min。
此外,本实施方式中的镜头马达1通过同时对第一子线圈7211以及第二子线圈7212输入信号,从而推动第一支架521并带动第二支架522相对底座20沿X轴方向移动。这样,通过同时对第一子线圈7211以及第二子线圈7212输入信号,使得动子50可以获得更大的X向驱动力,从而有利于提高第二支架522相对底座20沿X轴方向移动的速率,提高镜头马达1在X轴方向的响应速度。
上文具体介绍了镜头马达1是如何驱动镜头2移动的,下文还将结合相关附图具体介绍镜头组件400与摄像模组100中的其他部件的连接关系。
图35是图2b所示的摄像模组100在G-G线上的一种实施方式中的部分剖视图。图36是图2b所示的摄像模组100在G-G线上的一种实施方式中的剖视图。
如图3、图35和图36所示,模组外壳7可以盖合于模组底座5。模组底座5可以具有内部空间5a。棱镜4的至少部分可以收容于模组底座5的内部空间5a。示例性地,模组外壳7可以通过粘胶固定连接模组底座5。
示例性地,模组底座5可以包括第一上表面501与第二上表面502。第一上表面501与第二上表面502具有高度差。示例性地,第二上表面502可以高于第一上表面501。应理解,本实施方式中所称的高度均指在Z轴方向上的高度。
示例性地,第一上表面501可以设有第一透光孔5011。第二上表面502可以设有第二透光孔5021。第一透光孔5011可以通过模组底座5的内部空间5a连通至第二透光孔5021。
示例性地,棱镜4可以固定于模组底座5。其中,棱镜4可以高于第一上表面501。镜头马达1可以固定连接第一上表面501。此时,镜头马达1的安装空间1a可以与第一透光孔5011相对设置,且连通模组底座5的内部空间5a。棱镜4的一部分可以位于模组底座5的内部空间5a。棱镜4的另一部分可以位于镜头马达1的安装空间1a。
示例性地,棱镜4可以包括依次连接的第一面401、第一斜面402、第二面403以及第二斜面404。其中,第一面401可以包括第一区域4011和第二区域4012。镜头2与感光芯片601均可以位于第一面401背向第二面403的一侧。示例性地,镜头2可以与第一区域4011相对设置。感光芯片601可以与第二区域4012相对设置。
示例性地,电路模块6可以包括感光芯片601、模组电路板602以及滤光片603。感光芯片601可以固定于模组电路板602。滤光片603可以位于感光芯片601远离模组电路板602的一侧。其中,感光芯片601也称为图像传感器,或者感光元件。感光芯片601可以用于采集环境光线,并将环境光线所携带的图像信息转化为电信号。
示例性地,电路模块6可以固定连接第二上表面502。此时,滤光片603可以与第二透光孔5021相对设置。环境光线经过镜头2后,由棱镜4的第一面401的第一区域4011进入棱镜4,在棱镜4内部发生多次反射后,由第一面401的第二区域4012射出,依次穿过第二透光孔5021与滤光片603,最后进入感光芯片601(图36也示意出了环境光线的传播路径)。
可以理解的是,本实施方式中的摄像模组100通过在镜头马达1内设置安装空间1a,并将棱镜4的至少部分收容于安装空间1a内,使得镜头马达1能够相对棱镜4下沉,以降低镜头马达1的高度,从而实现摄像模组100的整体降高,有利于实现摄像模组100的薄型化设置。
上文具体介绍了摄像模组100在一种实施方式中的结构,下文还将结合相关附图具体介绍摄像模组100的几种实施方式。
图37是图36所示的摄像模组100的另一种实施方式的部分剖面示意图。图38是图36所示的摄像模组100的又一种实施方式的部分剖面示意图。
如图37所示,本实施方式中的摄像模组100与图35所示的摄像模组100的结构大致相同,相同部分不再赘述。不同之处在于,本实施方式中的摄像模组100的感光芯片601可以位于棱镜4的底部。示例性地,棱镜4的截面形状可以大致呈平行四边形。外界光线可以通过镜头组件400入射至棱镜4,经过棱镜4的反射进入感光芯片601。
如图38所示,本实施方式中的摄像模组100与图35所示的摄像模组100的结构大致相同,相同部分不再赘述。不同之处在于,本实施方式中的摄像模组100的感光芯片601可以位于棱镜4的周侧。示例性 地,棱镜4的截面形状可以大致呈梯形。外界光线可以通过镜头组件400入射至棱镜4,经过棱镜4的反射进入感光芯片601。
