下面将结合具体实施方式以及附图来对本申请提出的驱动模组、图像获取装置及电子设备进行进一步阐述。
请参阅图1，本申请实施方式提供一种驱动模组100、配置有驱动模组100的图像获取装置200以及配置有图像获取装置200的电子设备300，其中，驱动模组100可以应用在图像获取装置200中，以用于实现图像获取装置200的对焦功能和防抖功能。在本申请实施例中，电子设备300可以为但不限于为手机、平板电脑、笔记本电脑、台式电脑、运动相机、智能手表等智能电子装置。本实施方式的电子设备300以手机为例进行说明。
电子设备300可以包括壳体301以及设置于壳体301上的显示屏303。本实施例中，显示屏303通常包括显示面板，也可包括用于响应对显示面板进行触控操作的电路等。显示面板可以为一个液晶显示面板(Liquid Crystal Display，LCD)，在一些实施例中，显示面板可以同时为触摸显示屏。在本申请的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“里”等指示方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请而简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位，以特定的方位构造和操作，因此不能理解为对本申请的限制。
进一步地，请参阅图2，电子设备300还包括图像获取装置200，图像获取装置200设置于电子设备300的壳体301内。本申请实施例通过简化驱动模组100的结构，使得图像获取装置200的结构得到简化，进而提高电子设备300的美观性，有利于电子设备300的小型化。图像获取装置200可以包括透镜模组201以及上述的驱动模组100。透镜模组201包括至少一个透镜2011，透镜2011可以为凸透镜、凹透镜、平面镜、滤光镜片中的任一个，当透镜2011为多个时，多个透镜2011可以包括凸透镜、凹透镜、平面镜、滤光镜中的任意两个或两个以上的组合，多个透镜2011沿光轴方向O1依次排列设置，以用于将接收到的光线汇聚成像。图像获取装置200还可以包括图像传感器(图中未示出)，图像传感 器可以设置于驱动模组100上，也可以设置于驱动模组100之外，并与透镜模组201在光轴方向O1上排列设置。图像获取装置200通过驱动模组100驱动透镜模组201相对于图像传感器运动，使穿透透镜模组201的光线汇聚在图像传感器上，从而得到清晰的图像。
在一些实施方式中，图像获取装置200可以为电子设备300的前置摄像头、后置摄像头的任意一个或多个。图像获取装置200的类型也可以为黑白摄像头、红外摄像头、彩色摄像头等等，本申请对此不作限制。进一步地，在一些实施方式中，图像获取装置200上还可以安装其他的功能组件，例如，图像获取装置200上可以安装有受话器组件、闪光灯组件等功能组件中的任一个或多个。在本申请中，除非另有明确的规定或限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解。例如，可以是固定连接，也可以是可拆卸连接，或一体连接；可以是机械连接，也可以是电连接；可以是直接连接，也可以通过中间媒介间接相连，也可以是两个元件内部的连通，也可以是仅为表面接触。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
请参阅图3及图4，在本申请实施例中，驱动模组100包括底座10、载体30以及驱动组件50。在应用中，底座10可以固定于电子设备300的壳体内，载体30与底座10相嵌设置，并用于安装透镜模组201，驱动组件50设置于底座10与载体30之间，以驱动载体30相对于底座10沿透镜模组201的光轴方向O1运动，从而实现图像获取装置200的自动对焦功能。
在本申请实施例中，底座10包括导向部12以及固定设置于导向部12的凸出部14。在本申请中，除非另有明确的规定或限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解。例如，可以是固定连接，也可以是可拆卸连接，或一体连接；可以是机械连接，也可以是电连接；可以是直接连接，也可以通过中间媒介间接相连，也可以是两个元件内部的连通，也可以是仅为表面接触。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
导向部12与载体30相嵌设置，用于限制载体30相对于底座10的运动方向。凸出部14固定地设置于导向部12并相对导向部12凸出。载体30用于安装透镜模组201，其包括接触面34，接触面34沿光轴方向O1设置，并与凸出部14相对。当载体30相对于凸出部14运动时，接触面34与凸出部14可以接触并发生相对滑动，由于凸出部14相对于导向部12凸出，使凸出部14与接触面34的接触面积相对较小，二者之间相对滑动而产生的滑动摩擦力也相对较小，因此，导向部12与凸出部14的一体结构能够代替专有滑动导向结构，使驱动模组100的零部件数量相对较少，且结构得到简化。应当理解的是，在本 申请实施例中，某个部件“沿光轴方向O1设置”，可以理解为其延伸方向大致平行于光轴方向O1，例如，接触面34为平面时，其可以大致平行于光轴方向O1
进一步地，驱动组件50设置于底座10与载体30之间，并适于驱动载体30沿光轴方向O1运动，载体30在驱动组件50的驱动下发生相对于凸出部14、沿着光轴方向O1的运动，从而实现图像获取装置200的自动对焦功能。可见，在驱动模组100实现图像获取装置200的自动对焦的过程中，导向部12与凸出部14作为一体结构，能够代替专有滑动导向结构，使驱动模组100的零部件数量相对较少，且结构得到简化。具体而言，在应用时，驱动模组100安装在图像获取装置200上，图像获取装置200设置于电子设备300的壳体301内，透镜模组201安装于载体30，并在驱动组件50的驱动下沿光轴方向O1运动，从而实现图像获取装置200的自动对焦功能。并且通过减少驱动模组100的零部件，使得图像获取装置200及电子设备300的成本降低。
下文将结合具体的图示对本申请一些实施例的驱动模组100进行详细阐述。
在本实施例中，底座10还包括安装部16，安装部16为中空结构，其大致呈平板状，并用于安装载体30。安装部16设有光传输通道(图中未标出)，该光传输通道可以与图像传感器相对设置，以允许图像传感器捕获用于成像的光线。
导向部12连接于安装部16，在本实施例中，导向部12大致呈柱状结构，其大致垂直于安装部16，并沿着光轴方向O1设置。导向部12与安装部16之间可以为一体成型的连接结构，使驱动模组100的零部件数量相对较少，且结构得到简化。例如，二者可以通过注塑成型工艺或者浇注成型工艺、或者冲压成型工艺等，直接成型为一体结构。
导向部12的数量不受限制，在本实施例中，导向部12为两个，两个导向部12包括第一导向部121以及第二导向部123。应当理解的是，在本申请说明书的描述中，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。第一导向部121和第二导向部123分别位于安装部16的一侧的相对两端，第一导向部121以及第二导向部123上均设有至少一个凸出部14。在本申请的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“里”等指示方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请而简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位，以特定的方位构造和操作，因此不能理解为对本申请的限制。
凸出部14相对于导向部12的表面凸出，凸出部14与导向部12之间为一体成型的连 接结构，以减少驱动模组100的零部件数量。例如，凸出部14与导向部12可以通过注塑成型工艺或者浇注成型工艺、或者冲压成型工艺等，二者直接成型为一体结构。在一些实施例中，凸出部14的材料可以与导向部12或/及安装部16的材料相同或者不同。
例如，在一些实施例中，凸出部14与导向部12可以均由塑料制成，二者通过注塑成型工艺或者浇注成型工艺成型为一体结构。
又如，在另一些实施例中，如图5所示，导向部12或/及安装部16均由塑料制成，而凸出部14由金属制成，凸出部14通过嵌件成型工艺与导向部12成型为一体结构。制备时，将金属制成的凸出部14半成品放入模具中后，通过注塑等工艺成型导向部12的结构，从而使凸出部14的一端嵌入导向部14内部，另一端相对于导向部14的表面凸出，在该实施例中，通过将凸出部14设计为金属部件，并与塑料制成的导向部14通过嵌件工艺成型，能够在保证制备成本较低的基础上，利用金属部件的硬度较高、表面粗糙度较小等特性，保证凸出部14和接触面34之间的滑动摩擦力相对较小，且滑动摩擦损耗较小，从而保证载体30滑动顺畅、且结构稳定。
再如，在另一些实施例中，如图6所示，凸出部14与导向部12可以均由塑料制成，二者通过注塑成型工艺或者浇注成型工艺成型为一体结构，而凸出部14的表面141可以设置金属层1411，从而尽量避免载体30的滑动摩擦损耗，且保证凸出部14和接触面34之间的滑动摩擦力相对较小。金属层1411的材料可以包括铝合金、锌合金、镁合金、铁合金、铜、铁、铝、锌中的至少一种，金属层1411与表面141之间的连接方式可以为粘结、直接贴附，或者，金属层1411也可以采用激光刻蚀、电镀、电泳等中任一种工艺成型在表面141上。
进一步地，凸出部14的数量不受限制，请参阅图7，在本实施例中，凸出部14包括四个凸起结构，四个凸起结构中的两个设置于第一导向部121，另外两个设置于第二导向部123上。在本实施例中，凸出部14的表面141为曲面，在载体30运动时，表面141与载体30的部分结构相接触并产生滑动摩擦。进一步地，曲面结构以为球面、圆柱面、椭球面中的至少一种。表面141的曲面结构和接触面34之间的接触，可以为点接触或者线接触，能够大大减小接触面积，从而减小滑动摩擦力，从而保证载体30滑动顺畅。进一步地，凸出部14的表面141的表面粗糙度可以小于或等于Ra15mm，以利于进一步减小凸出部14和接触面34之间的摩擦。例如，表面141的表面粗糙度可以为Ra12.5mm、Ra6.3mm、Ra3.2mm、Ra1.6、Ra0.8mm、Ra0.4mm、Ra0.2mm、Ra0.1mm、Ra0.05mm。
在本申请实施例中，载体30与导向部12相嵌设置，载体30为中空结构，其大致呈矩 形框状，其设置有容纳部36，容纳部36用于安装透镜模组201。容纳部36为通孔结构，其沿着透镜模组201的光轴方向O1贯穿载体30，以便于透镜模组201采光。换而言之，容纳部36的通孔结构的轴线方向与光轴方向O1一致。
在本实施例中，载体30还设置有缺口32，缺口32位于载体30朝向导向部12的一侧并沿光轴方向O1贯穿载体30，导向部12可活动地嵌入缺口32中，以限制载体30相对于底座10的运动方向。在本实施例中，为适应导向部12的数量，缺口32可以为两个，两个缺口32包括第一缺口321以及第二缺口323，第一导向部121可活动地嵌入第一缺口321中，第二导向部123可活动地嵌入第二缺口343中。
请参阅图8，载体30的接触面34设置于载体30朝向导向部12的一侧，位于缺口32内，并沿光轴方向O1设置并与凸出部14相对设置。在本申请实施例中，某个部件“沿光轴方向O1设置”，可以理解为其延伸方向大致平行于光轴方向O1，例如，接触面34为平面时，其可以平行于光轴方向O1。载体30运动时，接触面34与凸出部14可以接触，二者之间产生滑动摩擦。
在一些实施例中，接触面34可以为一个，一个接触面34可以为载体30的表面的一部分，其大致平行于光轴方向O1。在另一些实施例中，接触面34可以包括第一表面341以及第二表面343，第一表面341以及第二表面343可以均为平面，且均大致平行于光轴方向O1。第一表面341连接于第二表面343的一侧，并与第二表面343共同形成导向槽345。导向槽345沿光轴方向O1设置，凸出部14可活动地容置于导向槽345中，以限制载体30相对于底座10的运动方向。进一步地，第一表面341和第二表面343之间的夹角小于180度，使导向槽345的横截面大致呈“V”形，从而进一步限制凸出部14的运动方向。
在其他一些实施例中，为了适应导向部12的数量，接触面34的数量可以为两个，相应地，导向槽345的数量也为两个。两个导向槽345均沿光轴方向O1设置，凸出部14可活动地容置于导向槽345中，以限制载体30相对于底座10的运动方向。两个导向槽345的横截面形状不受限制，例如，两个均为V形槽，或者两个均为矩形槽，或者其中一个为V形槽、另一个为矩形槽。
请参阅图9，在本申请实施例中，驱动组件50包括定子52以及动子54，定子52设置于安装部16，动子54设置于载体30，定子52能够在电流的激励下驱动动子54带动载体30运动。
在本实施例中，为了限制定子52在安装部16上的安装位置，且进一步缩减驱动模组100的厚度，安装部16可以设有安装槽161，定子52至少部分地嵌入安装槽161内。请 参阅图10，进一步地，为了限制动子54在载体30上的安装位置，载体30朝向安装部16的一侧可以设有容置槽38，动子54至少部分地嵌入容置槽38内，并与载体30固定连接。进一步地，定子52与动子54的具体结构不受限制。在一些实施例中，定子52可以为驱动电机，动子54可以为连接于驱动电机的滑块结构(例如，驱动电机可以配置有输出螺杆，而动子54可以为与该螺杆啮合的螺母。)
在本实施例中，定子52为线圈绕组，动子54为永磁体，该线圈绕组绕设的方向大致平行于光轴方向O1，如线圈绕组大致平铺在安装槽161内。进一步地，驱动组件50还可以包括导磁件56，导磁件56固定于导向部12并与动子54沿垂直于光轴的方向并列设置，且位于动子54产生的磁场内，从而通过导磁件56与动子54之间的磁力吸引作用限制动子54相对于定子52的位置。进一步地，导磁件56对动子54的吸引具有垂直于光轴方向O1的分量，使得载体30的接触面34与底座10的凸出部14接触。具体而言，导磁件56可以与动子54并列设置，如，导磁件56可以设置于导向部12背离载体30的一侧，导磁件56和载体30上的动子54在垂直于光轴方向O1的方向上大致并列(如大致平行相对设置)，从而使导磁件56对对动子54的吸引具有垂直于光轴方向O1的分量。在本申请实施例中，导磁件56可以不含有磁性，如导磁件56可以由铁氧体制成，或者，导磁件56本身可以为永磁体。导磁体56位于动子54的磁场中时，其受到动子54的磁力作用，二者之间形成相互吸引力以限制动子54相对于导磁件56(底座10)的位置，使得动子54在未受到定子52的作用力时基本不会脱离底座10。
在其他一些实施例中，定子52可以为永磁体，动子54可以为线圈绕组。当驱动组件50工作时，对其中的线圈绕组进行通电，通电的线圈绕组在永磁体的磁场中受到安培力作用，线圈绕组和永磁体可进行相对运动，因此通过控制线圈绕组电流的方向以及大小，可以使动子54可相对定子52进行往复运动。在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
在另一些实施例中，定子52和动子54二者可以均为线圈绕组，当驱动组件50工作时，对两个线圈绕组进行通电，两个线圈绕组之间可以形成磁场，在安培力作用下产生相 对运动，以使动子54可相对定子52进行往复运动。在又一些实施例中，驱动组件50为直线电机，驱动组件50通过控制动子54相对于定子52运动，使载体30相对于底座10运动。
请参阅图10及图11，在本申请实施例中，驱动模组100还可以包括电连接件70，电连接件70集成于底座10并与驱动组件50电性连接。电连接件70包括电导体72，电导体72用于传输激励驱动组件50的电信号以及电能。在本实施例中，电导体72为安装部12内的金属嵌件结构，电导体72的一端经由安装槽161的底壁暴露，并与驱动组件50电性连接。在其他一些实施例中，电导体72可以为金属镀层、金属走线，其贴敷在安装部16表面紧密连接，并与驱动组件50电性连接。在另一些实施例中，电导体72可以为激光成型的金属走线，其附着在安装部16的表面，并与驱动组件50电性连接。电导体72的另一端可以凸出于安装部16背离载体的一侧，以利于和电子设备100的控制主板电性连接，或与图像或者装置200的控制芯片电性连接。
在本申请实施例中，驱动组件50还可以包括位置传感器58，位置传感器58固定设置于安装部16，并用于感测动子54相对于定子52的位置。在本实施例中，位置传感器58设置于安装槽161内并与电连接件70电性连接。在一些实施例中，位置传感器58可以为磁传感器，例如，霍尔传感器，其可以通过磁场强度检测动子54和定子52之间的距离，然后向电连接件70输出信号，电连接件70根据信号来调节电流大小以控制动子54的位移大小，实现驱动模组100的闭环控制。在其他的一些实施例中，位置传感器58也可以为光电传感器，其可以利用光信号检测动子58和定子52之间的距离，然后回传信号至电连接件70，电连接件70根据信号来调节电流大小以控制动子54的位移大小，实现驱动模组100的闭环控制。
在本申请实施例中，驱动模组100还可以包括外壳90，外壳90为矩形中空结构，其朝向底座10的一侧敞开，为底座10、载体30、驱动组件50以及电连接件70的任一个或多个提供收容空间92，并于底座10连接共同形成一个封闭结构。
组装时，首先，将定子54放在制备成型的底座10上，其中，制备成型的底座10为一体结构，其包括导向部12、凸出部14、安装部16，安装部16还设置有电连接件70。然后，将动子52放在载体30的容置槽38内，把载体30叠放在安装部16上，使导向部12嵌入缺口32中，且凸出部14嵌入导向槽345。最后，将导磁件56固定在导向部12上，并与动子54沿垂直于光轴的方向并列设置。最后，将外壳90盖在载体30外，并与安装部16固定连接，使底座10、载体30、驱动组件50、电连接件70均收容在外壳90内，形成 模块化的结构，便于生产、组装。
使用时，电导体72根据控制指令向定子52输入电流，激励载体30相对于底座10沿光轴方向O1运动，接触面34会和凸出部14的表面接触并发生相对滑动，从而实现图像获取装置200的自动对焦功能。由于凸出部14相对于导向部12凸出，使凸出部14与接触面34的接触面积相对较小，二者之间相对滑动而产生的滑动摩擦力也相对较小，因此，导向部12与凸出部14的一体结构能够代替专有滑动导向结构，使驱动模组100的零部件数量相对较少，且结构得到简化。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不驱使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
