 本发明的实施方式
下面结合附图和实施方式对本申请作进一步说明。
本申请实施例提供了一种电子设备10，该电子设备10可以为手持终端或固定终端，手持终端包括例如手机或平板电脑等电子设备，固定终端包括例如台式电脑、显示器等电子设备。
在一实施例中，电子设备10包括移动机构100、摄像头模组500及外壳400，外壳400作为安装基体以用于安装移动机构100，移动机构100连接于摄像头模组500，参考图1所示的实施例，摄像头模组500在未使用时，至少部分位于外壳400内，在使用摄像头模组500时，移动机构100驱动摄像头模组500自外壳400中伸出；具体地，在其他实施例中，摄像头模组500也可替换为扬声器模组或传感器模组等电子元件，在此不做唯一限定。
在本实施例中，电子设备10还包括柔性电路板200和控制组件（图中未示出），控制组件用于实现电子设备10的电路控制功能，且控制组件设于外壳400内；请继续参阅图2所示，柔性电路板200的至少部分固接于外壳400，且柔性电路板200的两端分别与控制组件和摄像头模组500电连接，以使控制组件能够与摄像头模组500传输信号，例如电信号、控制信号等信号类型；在摄像头模组500相对于外壳400移动时，柔性电路板200随摄像头模组500的移动而发生形变，从而保持控制组件与摄像头模组500的电连接。在一实施例中，移动机构100包括移动组件110、驱动组件120以及导向件130，具体参阅图2和图7所示，驱动组件120用于提供驱动力；驱动组件120包括驱动单元121以及连接于驱动单元121输出端的驱动轴；移动组件110包括与驱动轴移动配合的移动件111以及设于移动件111远离驱动单元121输出端的连接件113，连接件113用于固定摄像头模组500；导向件130开设有第一槽部1311和与第一槽部1311连接的第二槽部1312，且第一槽部1311沿第一方向延伸；其中，移动件111与导向件130相对移动设置，驱动组件120驱动移动件111带动摄像头模组500沿第一槽部1311作直线运动并沿第二槽部1312作旋转运动。
在本实施例中的移动机构100中，用于连接摄像头模组500的连接件113和驱动组件120的驱动单元121分别设置于驱动轴的相对两端，并且设置有用于对移动件111进行导向的导向件130，驱动组件120启动之后可以驱动移动件111沿第一槽部1311直线运动或沿第二槽部1312旋转运动。由此，通过设置导向件130、驱动组件120以及移动组件110的相互配合，可以使移动机构100具有紧凑的体积，并且可以驱动连接件113进行两段移动，功能性好。
具体地，参阅图1和图2所示，外壳400包括第一壳体410和第二壳体420，第一壳体410连接于第二壳体420，且移动机构100设于第一壳体410上；第一壳体410与第二壳体420可通过螺钉连接、卡扣连接、粘接等可拆卸方式进行连接，以便于本电子设备10的组装；第一壳体410与第二壳体420也可采用如焊接、铆钉连接等固定连接方式，使用固定连接方式连接第一壳体410和第二壳体420之后，电子设备10的壳体400便无法打开。
进一步地，在一实施例中，第一壳体410上开设有通孔411，电子设备10还包括设于通孔411处的密封组件300，摄像头模组500与密封组件300相对滑动设置，以用于对摄像头模组500与外壳400进行密封。
具体如图1所示，在本实施例中，第一壳体410具有外壁面413，摄像头模组500具有外端面511，密封组件300具有盖端面321；当摄像头模组500未伸出时，外壁面413、外端面511与盖端面321形成一完整的面，以使本电子设备10能够在通孔411的外侧处于平整的状态，一方面可以避免操作人员在使用本电子设备10时被摄像头模组500和/或驱动组件120划伤，另一方面，在使用电子设备10时，由于摄像头模组500未凸出外壳400，从而可以对摄像头模组500进行保护，避免摄像头模组500磕碰损坏；
通过上述设置，当摄像头模组500从外壳400伸出时，密封组件300能够对摄像头模组500与外壳400之间的缝隙进行密封，从而使电子设备10具有防尘、防水等防护功能，以使电子设备10具有更高的防护等级。
具体在一实施例中，密封组件300包括密封环310以及压盖320，参阅图2和图4所示，压盖320连接于外壳400，密封环310设于压盖320与外壳400之间，摄像头模组500与密封环310滑动连接。
在本实施例中，密封环310通过压盖320固定在第一壳体410上，参阅图1所示，压盖320的外壁还与第二壳体420相适配，第一壳体410与第二壳体420组合之后，通过压盖320固定，以使密封环310与第一壳体410和第二壳体420贴合密封；密封环310设有与摄像头模组500相适配的密封孔，摄像头模组500嵌设于密封孔内，具体地，密封环310可采用如橡胶密封环、硅胶密封环等密封元件进行密封。
在其他实施例中，密封组件300还包括与外壳400相对移动设置的盖板（图中未示出），当摄像头模组500位于外壳400内时，盖板盖设于密封孔，当需要移动摄像头模组500时，盖板与外壳400相对移动，以使摄像头模组500能够从密封孔中伸出；具体地，盖板可以转动连接于外壳400，参考图2所示的摆放状态，盖板的转轴可以与Y方向相平行，转轴也可以设置与盖端面321相平行并垂直与Y方向，在一些实施例中，盖板也可以包括两部分组成，且分别连接于外壳400，在此不做唯一限定。参阅图3及图7所示，在一实施例中，移动件111活动连接于导向件130，并能够相对于导向件130移动；导向件130上开设有至少部分沿X方向延伸的导向槽，导向部1111与导向槽滑动配合。在本实施例中，根据需求设置对应形式的导向槽，驱动组件120驱动移动件111移动时，导向槽即可对导向部1111进行导向，以使移动件111能够稳定且按照预设方式进行移动，移动件111首先在驱动组件120的驱动作用下沿X方向移动，直至摄像头模组500完全从外壳400中伸出时，之后，摄像头模组500可与外壳400相对转动或移动。
在其他实施例中，导向槽可设置为仅沿X方向延伸，在使用本实施例中的电子设备10时，移动机构100仅能够将外壳400内部的摄像头模组500沿X方向推出外壳400，以使摄像头模组500伸出；当摄像头模组500伸出外壳400之后达到预定位置，驱动组件120即停止运行。
具体地，导向件130套设于移动组件110上，导向槽包括上述的第一槽部1311和第二槽部1312，移动件111的外壁上设有与第一槽部1311和第二槽部1312相适配的导向部1111，参阅如图7和图10，在X方向上，第二槽部1312位于第一槽部1311的下游；第一槽部1311沿X方向延伸，导向部1111在第二槽部1312内滑动时，移动件111与导向件130相对转动。
由此设置，摄像头模组500即可分别在第一槽部1311和第二槽部1312的导向作用下沿不同的方向进行移动，导向部1111部在第一槽部1311内移动时，摄像头模组500沿X方向伸出外壳400，当摄像头模组500完全伸出外壳400之后，导向部1111即运动至第二槽部1312，并在第二槽部1312的导向作用下驱动摄像头模组500沿导向件130的中心轴旋转，由此即可实现摄像头模组500的旋转功能，并且可以对摄像头模组500在X方向上的移动进行限位。
参考图10所示，在一实施例中，第二槽部1312沿导向件130中心轴线的径向方向环绕导向件130设置。在本实施例中，第一槽部1311与第二槽部1312在沿与第一壳体410的投影大致为L型，并且第二槽部1312至少部分环绕导向件130的筒体131设置，第二槽部1312的前端与后端不相连接，且前端连接于第一槽部1311，当导向部1111移动至第二槽部1312内时，摄像头模组500便不再沿X方向移动，并在驱动组件120的驱动作用下绕筒体131的中心轴线旋转，以实现旋转功能；例如当摄像头模组500为摄像模组时，可以实现电子设备10向前拍摄以及向后拍摄的功能，仅需通过转动摄像头模组500的朝向即可。
参阅图2和图3所示，电子设备10中的摄像头模组500处于缩入状态，此时导向部1111位于第一槽部1311远离第二槽部1312的一端，并可以通过第二支架133进行限位；参阅图5所示，电子设备10中的摄像头模组500处于伸出状态，此时导向部1111移动至第二槽部1312的后端。
参考图12所示，在另一实施例中，第二槽部1312沿导向件130的中心轴线螺旋设置，并自第一槽部1311朝远离驱动单元121输出端的方向延伸。使用本实施例中的电子设备10，当导向部1111自第一槽部1311移动至第二槽部1312内时，移动件111便会在导向部1111的导向作用下绕筒体131的中心轴旋转，由于第二槽部1312沿螺旋方向设置，所以当导向部1111移动至第二槽部1312内时，摄像头模组500便可以开始沿第二槽部1312的螺旋方向进行旋转，直至到达第二槽部1312远离第一槽部1311一侧的端部，并相对于外壳400沿沿X方向移动预设距离，该预设距离为X方向上第二槽部1312的后端至第一槽部1311的距离。在其他实施例中，也可以根据需求设置对应结构的第一槽部1311和第二槽部1312，在此不做唯一限定。具体地，在一实施例中，驱动轴包括与移动件111螺纹配合的螺杆122，驱动单元121驱动螺杆122旋转，以驱动移动件111带动摄像头模组500沿第一方向作直线运动并沿第二槽部1312作旋转运动。可以理解地是，在本实施例中，螺杆122旋转时，通过螺杆122与移动件111的螺纹配合，即可驱动移动件111沿X方向的正向或反向移动；移动组件110沿X方向的延伸方向设置，以使移动组件110具有更为紧凑的结构，缩小了移动机构100在Y方向上的尺寸，以使移动机构100能够更加便于布置。在其他实施例中，螺杆114也可以替换为蜗杆，移动件111上开设有与蜗杆相适配的齿形，由此设置，当蜗杆旋转时，也可以驱动移动件111沿X方向移动。
摄像头模组500连接于移动组件110，驱动组件120动力连接于移动组件110以用于驱动摄像头模组500相对于外壳400移动。参考图2、图7和图10所示实施例，移动组件110包括移动件111、弹性件112以及连接件113，连接件113活动连接于移动件111，并能够相对于移动件111移动；弹性件112设于移动件111内，弹性件112在第一方向上的相对两端分别连接于移动件111和连接件113，定义X方向为第一方向；驱动组件120用于驱动移动件111和/或弹性件112沿X方向移动，以通过弹性件112的弹性作用驱使连接件113沿X方向移动，摄像头模组500即可在连接件113的带动下沿X方向伸出外壳400。具体地，驱动组件120可以连接于移动件111，以通过驱动移动件111而带动弹性件112移动，也可以连接于弹性件112，并通过驱动弹性件112以驱动摄像头模组500伸出外壳400，在其他实施例中，驱动组件120也可以连接于移动件111和弹性件112，并带动移动件111和弹性件112一同移动。
本实施例中的移动机构100中，通过设置与移动件111相对滑动的连接件113，以及分别连接于移动件111和连接件113的弹性件112，移动件111与连接件113未受到外力作用时，弹簧处于预压状态，也就是处于原长状态，当驱动组件120驱动移动件111以及弹性件112沿X方向移动时，连接件113能够在弹性件112的推力作用下沿X方向移动，当连接件113受到外部冲击时，连接件113便会相对于移动件111移动，并将冲击力传导至弹性件112，此时弹性件112便可以吸收冲击力，并对连接件113提供减震作用。
本实施例中的移动机构100，通过将分别连接于移动件111和连接件113的弹性件112设置在移动件111内，一方面，在连接件113受到冲击时，弹性件112可以为连接件113提供减震、吸震的作用，使用效果好；另一方面，通过如此设置，以使本移动机构100具有紧凑的结构，体积小巧，便于布置与安装。
可以理解地是，在本实施例中的电子设备10中，当摄像头模组500受到冲击时，移动机构100中的弹性件112元件能够吸收摄像头模组500受到的冲击力，从而为摄像头模组500提供减震、吸震的作用，从而减少摄像头模组500受到的冲击以对摄像头模组500进行保护，使用效果好。
具体地，参阅图7和图10，移动件111包括依次相接的前端部1114、中间部1113以及驱动部1112，前端部1114与中间部1113均为两端开口的筒状结构，驱动部1112与驱动轴螺纹连接，中间部1113的一端与驱动部1112固定连接、另一端与前端部1114固定连接，连接件113包括收容于中间部1113和前端部1114内的第一连接部1131第一连接部1131以及伸出前端部1114远离中间部1113一端开口的第二连接部1132第二连接部1132，第二连接部1132第二连接部1132与摄像头模组500连接。在一实施例中，弹性件112为预压螺旋弹簧，弹性件112设于中间部1113内并间隔套设于驱动轴，弹性件112一端抵接于驱动部1112、另一端与第一连接部1131连接。
具体在一实施例中，请参阅图7至图10所示，第一连接部1131上设有凸出延伸的限位部1131a，限位部1131a通过弹性件112的弹性作用抵接于前端部1114靠近驱动部1112的一端；前端部1114上设有自前端部1114靠近驱动部1112的一端向驱动部1112方向延伸的第一延伸部1114a，限位部1131a通过弹性件112的弹性作用抵接于第一延伸部1114a靠近驱动部1112的一端；前端部1114包括与中间部1113固定连接的第一端部1114b，第一延伸部1114a自第一端部1114b的内边缘延伸形成。
可以理解地是，由于连接件113与中间部1113可相对移动，在X方向上，连接件113朝向驱动部1112的一端由弹性件112进行限位；当连接件113未受到冲击时，第一延伸部114a抵接于限位部1131a，由此，移动件111即可对连接件113在X方向的相对两端进行限位，并且连接件113可以沿X方向的反向进行移动，在不影响弹性件112吸震、减震效果的前提下，也可以避免连接件113从移动件111中脱出，使用效果好。
具体地，螺旋弹簧的截面为矩形，且螺旋弹簧的一端抵接于驱动部1112；驱动组件120包括驱动单元121以及传导件123，传导件123分别动力连接于驱动单元121和螺杆122，并用于调节驱动单元121输出动力的方向以及速度。
在一实施例中，螺旋弹簧的内径大于螺杆122的外径。由此设置，当弹性件112受到连接件113的压力而收缩时，筒体131的内壁能够对弹性件112进行支撑，从而避免弹性件112在径向方向上发生较大的形变；同时弹性件112的内环与螺杆122间隔设置，也可以避免螺杆122在旋转过程中与弹性件112发生摩擦，从而提高了本移动机构100的耐用性。
具体在一些实施例中，驱动单元121可采用驱动电机，传导件123为减速器，以用于对驱动电机的输出端进行减速，并驱动螺杆122旋转，在本实施例中，驱动组件120、传导件123和螺杆122沿X方向依次设置；在其他实施例中，驱动单元121也可以与螺杆122平行设置，传导件123可包括减速器以及齿轮组，该齿轮组包括两个相互啮合的圆柱齿轮，且两个齿轮的旋转轴线均与X方向相平行，由此设置，相对于上一实施例，移动机构100在X方向上的长度尺寸得以缩小，以使移动机构100利用Y方向上的空间；在一些实施例中，齿轮组也可以采用两个相互啮合的斜齿轮，从而改变驱动单元121的布置方向；传导件123也可以采用皮带传动机构进行传动，在此不做唯一限定。
在一些实施例中，参阅图7和图8，螺杆122包括杆体1221和限位环1222，杆体1221与驱动部1112螺纹配合，限位环1222设于杆体1221远离驱动组件120的一端，限位环1222用于对驱动部1112在X方向上的移动进行限位。可以理解地是，在本实施例中，通过设置限位环1222，当驱动部1112沿杆体1221移动至末端时，驱动部1112朝向连接件113的一端即抵接于限位环1222，从而避免驱动部1112是螺杆122上脱出。导向件130还包括套设于螺杆122上的轴承134，由此设置，螺杆122可通过轴承134的支撑与筒体131相对转动，不仅能够降低螺杆122的摩擦损耗，同时又可以提高螺杆122的旋转平顺度，使用效果好。
参阅图13所示，在一实施例中，移动机构100还包括套设于导向件130上的防尘套114，且防尘套114覆盖导向槽。由此设置，防尘套114可以在不影响导向部1111移动的前提下遮盖导向件130上的导向槽，由此即可隔绝大部分外部环境中的灰尘，从而避免灰尘落入导向部1111与导向槽之间，以提高移动机构100的耐用性；具体地，防尘套114设于第一支架132和第二支架133之间，且防尘套114与第一支架132和/或第二支架133通过卡接配合，以此对防尘套114进行固定，避免防尘套114移动。
进一步地，移动件111与连接件113之间设有同步结构，同步结构用于在移动件111相对于导向件130转动时驱动连接件113转动。
参阅图10所示，在一实施例，同步结构包括平行朝的第一同步面1114c和第二同步面1131b；移动件111还包括前端部1114，前端部1114设于靠近连接件113的一端，第一同步面1114c设于前端部1114上，第二同步面1131b设于连接件113上；同步结构优选设置为两组，且自筒体131的中心轴线对称设置；可以理解地是，当连接件113连接于移动件111时，第一同步面1114c与第二同步面1131b贴合，由此，当移动件111旋转时，连接件113即可通过同步结构的驱动以随移动件111同时旋转。
在其他实施例中，同步结构也可以包括滑动配合的凸块和凹槽，且凹槽沿X方向延伸设置，凸块和凹槽中的一个设于移动件111上，凸块和凹槽中的另一个设于连接件113上，由此设置，连接件113与移动件111可在X方向上相对滑动，弹性件112可以为连接件113提供吸震功能；同时，当移动件111旋转时，凸块与凹槽的内壁抵接，以驱动连接件113与移动件111同步旋转。
参阅图2所示，移动机构100还包括均连接于第一壳体410的第一支架132和第二支架133，且第一支架132和第二支架133分别设于导向件130的相对两端，安装导向件130时，可以首先将第一支架132或第二支架133中的任意一个固定于第一壳体410上，之后安装导向件130和另一个支架，拆装便捷。
在本实施例中的电子设备10中，设置有上述实施例中的移动机构100，移动机构100可以驱动摄像头模组500沿X方向往复运动，以实现摄像头模组500的伸出、缩回动作，并且可以驱动摄像头模组500进行旋转动作，从而实现摄像头模组500的调节功能。通过设置上述实施例中具有紧凑体积的移动机构100，可以便于电子设备10的结构优化，在满足摄像头模组500的调节功能的前提下，使电子设备10具有更紧凑的体积，使用效果好。
具体地，摄像头模组500包括镜头组件510以及连接于镜头组件510的安装支架520，安装支架520位于镜头组件510靠近移动组件110的一侧；安装支架520与移动组件110连接，并随移动组件110带动沿螺杆122的轴向作旋转运动或沿第一方向作直线运动；移动机构100还包括套设于安装支架520并与安装支架520活动连接的环形的引导件140，引导件140与相邻的外壳400滑动配合；安装支架520包括设于引导件140内的连接轴522、以及沿连接轴522轴向间隔设置的卡接部524，引导件140卡接于卡接部524之间并随摄像头模组500沿第一方向相对外壳400滑动；引导件140与相邻的外壳400中的其中一个具有滑动凸起412，另一个设有与滑动凸起412配合的滑槽1421，滑槽1421沿第一方向延伸并限定滑动凸起412的滑动路径。
在本实施例中的电子设备10中，摄像头模组500在引导件140的支撑作用下滑动配合于外壳400，驱动组件120通过驱动移动组件110以带动引导件140相对于外壳400移动，并能够驱动摄像头模组500沿第一方向直线移动或沿驱动组件120中的螺杆122做旋转运动。在本实施例中的电子设备10中，通过在安装摄像头模组500的引导件140与外壳400之间设置相配合的滑动凸起412以及滑槽1421，可以提高摄像头模组500的移动平稳性，使用效果好。
电子设备10还包括与摄像头模组电连接的柔性电路板200，参阅图11所示，柔性电路板200包括与摄像头模组500电连接的电连接段210，自电连接段210延伸并套设于安装支架520的延伸段220以及自延伸段220朝远离摄像头模组500方向延伸的弯折段230，弯折段230沿第一方向至少两次反向弯折延伸。
在本实施例中的电子设备10中，柔性电路板200至少部分固定于引导件140上，在移动机构100驱动摄像头模组500移动的过程中，驱动组件120驱动引导件140移动，进而带动安装支架520上的摄像头模组500移动，此时连接于引导件140的固定部220与摄像头模组500处于相对固定的状态，仅弯折段230在X方向上发生长度的改变。
可以理解的是，在本实施例中的电子设备10，通过将柔性电路板200的延伸段220与移动机构100中的引导件140连接，当摄像头模组500相对于外壳400移动时，可以有效地避免发生柔性电路板200与摄像头模组500之间发生弯折而导致柔性电路板200断裂的情况，柔性电路板200的耐用性得以提高，电子设备10的可靠性也得以进一步提升，使用效果好。
参阅图2所示，电子设备10处于缩入状态，此时柔性电路板200的弯折段230至少部分处于层叠状态；而当电子设备10变化至图5所示的伸出状态，弯折段230便由层叠状态变化为展开状态，以使柔性电路板200能够连接于摄像头模组500以及控制组件。
进一步地，参阅4所示，延伸段220朝引导件140延伸形成有第一固定脚221，且第一固定脚221固定于引导件140上
可以理解地是，由于柔性电路板200具有一定的弹性，并且延伸段220部分处于卷曲状态，所以柔性电路板200在延伸段220中会储存弹性势能，并具有展开的趋势；本实施例中的柔性电路板200通过将第一固定脚221固定于引导件140上，可以避免延伸段220与引导件140分离，从而在摄像头模组500未旋转时对柔性电路板200进行固定，避免柔性电路板200出现展开和/或散开的情况，柔性电路板200的固定稳定性较好，使用效果好。
参阅图4至图6所示，在一实施例中，引导件140包括环形主体141以及自环形主体141朝远离摄像头模组500的方向延伸的延伸臂142，延伸臂142沿X方向延伸，延伸臂142与相邻的外壳400滑动配合；延伸臂142上开设有滑槽1421，外壳400朝向滑槽1421凸设有滑动凸起412，滑动凸起412至少部分收容与滑槽1421内。
通过设置沿X方向延伸的延伸臂142与外壳400滑动配合，在引导件140与外壳400相对滑动的过程中，通过滑槽1421与滑动凸起412的配合，一方面可以对引导件140的移动进行导向，以使引导件140能够沿X方向进行直线移动，同时通过设置沿X方向延伸的滑槽1421与滑动凸起412的滑动配合，滑动凸起412的外壁与滑槽1421的内壁之间相互滑动，通过面与面之间的贴合滑动，从而可以提高引导件140的滑动平稳性，使用效果好。在其他实施例中，滑槽1421也可以和滑动凸起412交换设置的位置，由此设置，也可以实现导向作用，在此不做唯一限定。
进一步地，延伸臂142的数目为两组，且两组延伸臂142分别设置于连接轴522的两侧，每一延伸臂142上均设置滑槽1421，引导件140还包括架设于延伸臂142之间并与主体间隔设置的安装臂143，弯折段230靠近延伸段220的一端与安装臂143贴合。
通过设置两组相平行的延伸臂142与滑动凸起412配合，在引导件140与外壳400相对移动的过程中，可以对引导件140进行导向，从而进一步提高引导件140的滑动平稳性，使用效果好。
在一实施例中，弯折段230靠近安装臂143的一端延伸形成有第二固定脚222，第二固定脚222与安装臂143固定；至少两个第二固定脚222设置于延伸段220相对连接轴522的两侧。
在本实施例中，柔性电路板200的延伸段220通过第一固定脚221和第二固定脚222配合以固定在引导件140上，不仅可以避免延伸段220发生展开的情况，同时也可以避免摄像头模组500在移动时，柔性电路板200与引导件140发生分离，从而避免电连接段210发生弯折的情况。在其他实施例中，也可以设置多个第二固定脚222，例如设置有三个或三个以上的第二固定脚222，通过设置多个第二固定脚222，可以提高延伸段220的固定稳定性。
具体地，电连接段210包括与摄像头模组500固定电连接的电连接片211以及由电连接片211弯折延伸至延伸段220内部的舌板212，舌板212与延伸段220连接。参阅图6和图7所示的实施例，连接轴522与引导件140转动配合，驱动组件120还用于驱动安装支架520沿连接轴522旋转；安装支架520开设有沿X方向延伸的连接槽523，舌板212穿设于连接槽523内，并通过电连接片211连接于镜头组件510。
由此设置，当引导件140相对于导向件130旋转时，延伸段220固定于引导件140上，电连接段210的与摄像头模组500以及引导件140一同旋转，延伸段220也同时部分展开，通过将舌板212设于连接槽523内，可以避免引导件140和/或摄像头模组500在旋转过程中对柔性电路板200造成积压、撕裂等操作，同时也可以对电连接段210进行保护，使用效果好。
具体地，延伸段220为至少连续环绕安装支架520两圈的环状结构，由此设置，摄像头模组500在伸出外壳400之后，可以沿驱动轴的中心轴线旋转至少两圈。
参阅图6和图7所示，引导件140开设有旋转孔，连接槽523包括设于支架本体521上的通槽5211以及设于连接轴522上的缺口位5221。
可以理解地是，通过在连接轴522上开设用于容纳柔性电路板200的缺口位5221，当连接轴522在旋转孔内转动时，旋转孔内与连接轴522之间总保持有用于容纳柔性电路板200空间，也就是缺口位5221，由此设置，即可在不影响柔性电路板200传输信号的过程中使柔性电路板200能够随摄像头模组500一同转动，避免使柔性电路板200发生扭曲、弯折的情况，柔性电路板200的使用寿命得以提高。
以上所述的仅是本申请的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本申请创造构思的前提下，还可以做出改进，但这些均属于本申请的保护范围。
