请参阅图1至图4，本申请实施例提出了一种驱动组件10，驱动组件10是在照相机或者其他类似成像仪器中，通过光学元器件的设置来避免或者减 少拍摄过程中出现的仪器抖动现象，从而提高成像质量的组件。驱动组件10所包括的零部件根据工作原理的不同而会有不同，在本实施例中，该驱动组件10包括底板100、支架200以及马达300。
其中，底板100是用于承载、安装、连接、定位驱动组件10中其它各零部件的主体部件，底板100的其中一个表面即为承载面110，底板100的形状、尺寸等根据驱动组件10中所需要承载、安装、连接、定位的各部件或组件来确定，此处不作限制。支架200设置于承载面110，支架200上沿垂直于承载面110的方向开设有通孔210，承载面110与通孔210共同限定出容纳腔220。即支架200与底板100的承载面110连接，支架200中的通孔210与底板100共同围设出一个相对隔绝的空间即为容纳腔220。驱动组件10中的各部件或组件均可以安装在该容纳腔220内，从而支架200的外壁以及底板100可以对容纳腔220内的部件或组件起到保护作用，确保其能够正常工作。
同时，马达300设置于容纳腔220内，马达300可以带动驱动组件10中的部件或组件运动以实现防抖功能。因此，马达300的结构形式、马达300的尺寸等均不作限制，只需要满足马达300远离承载面110的一端凸出于通孔210。这样，马达300能够凸出至支架200外部，支架200不需要将马达300整体包覆在内，减小了支架200的尺寸。因此，支架200的结构可以采用金属薄壳冲压而成，它的宽度尺寸与厚度尺寸都较小，并且，金属薄壳上的通孔210的孔径开口较大，有利于马达300由该通孔210凸出至支架200外部。
基于本申请实施例的驱动组件10，通过将马达300设置于由承载面110与通孔210共同限定出的容纳腔220内，并令马达300的一端凸出于通孔210，这样，马达300能够凸出至支架200外部，支架200不需要将马达300整体包覆在内，可以减小支架200的尺寸，从而减小了整个驱动组件10所占用的空间，有利于实现其结构小型化。
支架200设置于承载面110，支架200与底板100之间可以采用胶水粘 接、螺钉栓接或本领域中其它的连接件来实现连接。而为了进一步减小驱动组件10所占用的空间，在一个实施例中，请参阅图1至图2，底板100包括安装板120及位于安装板120与支架200之间的主电路板130，此时，承载面110为主电路板130背离安装板120的表面。支架200面向主电路板130的一侧沿垂直于承载面110的方向凸出设置有连接部230，主电路板130上对应连接部230开设有缺口部131，以使连接部230能够穿过缺口部131并与安装板120的表面固定连接。通过在主电路板130上开设缺口部131，令支架200上的连接部230穿过缺口部131并与安装板120的表面固定连接，可以降低支架200被垫起的高度，从而进一步减小整个驱动组件10所占用的空间，有利于实现其结构小型化。并且，相较于与主电路板130固定连接，支架200与安装板120之间的固定更方便，例如，支架200与安装板120可以使用镭射熔接的接着方式，大幅增强接着效果，连接更紧固。此时，安装板120与主电路板130之间可以没有借助外部结构进行连接，而仅仅依靠支架200将主电路板130卡合在支架200与安装板120之间的空间内。
而为了加强支架200与主安装板120连接的紧固程度，沿平行于承载面110的方向，支架200相对的两侧分别设置有至少一个连接部230，主电路板130上与各连接部230一一对应开设有多个缺口部131。通过在支架200沿平行于承载面110的方向上相对的两侧分别设置至少一个连接部230，并在主电路板130上与各连接部230一一对应开设有多个缺口部131，利用多个连接部230与安装板120之间的配合使支架200相对的两侧均与安装板120紧密固定，在减小整个驱动组件10所占用的空间的同时，也确保了其结构的紧密程度。
如上文中所述，支架200的结构可以采用金属薄壳冲压而成，它的宽度尺寸与厚度尺寸都较小。但是，金属薄壳冲压出来的结构特征单纯，无法和马达300结构很好的匹配。因此，在其中一个实施例中，如图1及图3所示，驱动组件10还包括设置于容纳腔220内的垫圈400，垫圈400套设于马达300外，且垫圈400背离马达300的一侧与支架200的内壁抵接。通过在马达300 外套设垫圈400，可以填充马达300与支架200内壁之间的空隙，使马达300被紧密固定在支架200内部，提升了驱动组件10整体的紧密程度及结构一体性。并且，垫圈400可以适应各种不同种类的马达300，提升了驱动组件10的适用场景范围。垫圈400的形状、大小、尺寸等可以随马达300的不同而灵活调整，因此，本实施中的驱动组件10可以适用于多种不同使用需求的场景下。
进一步的，为了避免垫圈400由支架200的通孔210处脱离容纳腔220，在其中一个实施例中，支架200背离承载面110的一侧设置有向通孔210的中心方向延伸的阻挡部240，垫圈400面向阻挡部240的一侧与阻挡部240抵接。通过设置阻挡部240，可以对垫圈400起到限位作用，避免垫圈400由支架200的通孔210处脱离容纳腔220，提升了驱动组件10整体的紧密程度及结构一体性。阻挡部240的作用是防止垫圈400由支架200的通孔210处脱离容纳腔220，并且阻挡部240不应妨碍容纳腔220内其他部件的正常工作，因此，阻挡部240向通孔210的中心方向延伸的幅度不宜过大。
底板100的承载面110与通孔210共同限定出容纳腔220，而底板100的尺寸还可以大于通孔210的孔径，此时，承载面110在支架200外还有一片或多片区域，如图1至图3所示，在其中一个实施例中，承载面110包括位于支架200外的连接区111，驱动组件10还包括位于容纳腔220内环绕马达300设置的第一电路板500、贴附于连接区111的第二电路板600以及连接第一电路板500与第二电路板600的第一弯折段700，支架200上在靠近连接区111的位置处开设有开口部250，第一弯折段700穿过开口部250以连接第一电路板500与第二电路板600。通过在支架200上靠近连接区111的位置处开设开口部250，就可以令第一弯折段700穿过开口部250而分别连接第一电路板500与第二电路板600，结构简单，连接方便，第一弯折段700没有占用额外的空间，进一步减小了整个驱动组件10所占用的空间，有利于实现其结构小型化。此时，第一电路板500与第二电路板600可以是硬质电路板，可以是软质电路板，还可以是软硬结合板。而第一弯折段700可 以采用软质电路板以便于进行弯折。第一电路板500、第一弯折段700、第二电路板600以及主电路板130之间可以进行信号传输。
驱动组件10中还可能包括用于进行光线过滤的滤光片，用于控制动作部件进行动作的控制芯片等，因此，如图3至图4所示，在其中一个实施例中，驱动组件10还包括设置于马达300与承载面110之间的托架800，托架800上可以开设沿垂直于承载面110方向凹陷的安装槽，驱动组件10中的滤光片或感光元件或其它元件可以安装在托架800的安装槽中。而托架800上对应第一弯折段700开设有第一避位槽810。通过在托架800上对应第一弯折段700开设第一避位槽810，便于第一弯折段700的弯折连接，并且尽可能地缩小了托架800的尺寸，从而减小了整个驱动组件10所占用的空间，有利于实现其结构小型化。
请继续参阅图3至图4，类似的，在其中一个实施例中，驱动组件10还包括设置于托架800与承载面110之间的第三电路板900以及连接第一电路板500与第三电路板900的第二弯折段1000，托架800上对应第二弯折段1000开设有第二避位槽820。第三电路板900与第二电路板600不同的是，第三电路板900位于托架800与承载面110之间，即第三电路板900位于容纳腔220内部，而第二电路板600位于连接区111内，即第二电路板600位于容纳腔220外部，而第一电路板500环绕马达300设置，故第一弯折段700是沿着朝向连接区111的方向弯折，而第二弯折段1000是沿着朝向容纳腔220的方向弯折，第一弯折段700与第二弯折段1000的弯折方向相反。通过在托架800上对应第二弯折段1000开设第二避位槽820，便于第二弯折段1000的弯折连接，并且尽可能地缩小了托架800的尺寸，从而减小了整个驱动组件10所占用的空间，有利于实现其结构小型化。
综上所述，通过将驱动组件10中的马达300设置于由承载面110与通孔210共同限定出的容纳腔220内，并令马达300的一端凸出于通孔210，这样，马达300能够凸出至支架200外部，支架200不需要将马达300整体包覆在内，可以减小支架200的尺寸，从而减小了整个驱动组件10所占用的空间， 有利于实现其结构小型化。
使用时，驱动组件10中的底板100、支架200以及马达300的固定部(即定子)均保持相对固定，而马达300的活动部(即动子)能够相对固定部进行运动，将活动部与待驱动的部件连接，即可带动待驱动部件进行运动。例如，可以将镜头安装到容纳腔220内并与马达300的活动部连接，这样，驱动组件10就能够带动镜头运动以实现变焦或防抖功能。类似的，还可以将安装有感光元件的托架800与马达300的活动部连接，这样，驱动组件10就能够带动感光元件运动以实现变焦或防抖功能。同时，驱动组件10中相互电连接的主电路板130、第一电路板500、第二电路板600以及第三电路板900传递电信号以便对马达300的活动部的动作进行控制，其中，直接或间接与该活动部相连接的电路板可以采用柔性电路板来制作，柔性电路板能够变形以配合活动部进行同步运动。
