请参阅图2-图4，作为本实施例一种改进方式，摄像机构10包括镜头模组11和连接于镜头模组11一侧的支撑杆12，镜头模组11包括壳体111和安装于壳体111内的摄像头112，支撑杆12与壳体111固定连接，摄像头112优选为两个，两个摄像头112对称安装在壳体111的内部。可以理解的是，摄像头112的数量并不局限于上述的两个，例如一个或者多个也是可以的。
驱动机构40与驱动轴30远离镜头模组11的一端连接以用于驱动该驱动轴30旋转，升降件20套设于驱动轴30并位于镜头模组11朝向驱动机构40的一侧，升降件20贯穿设有相互间隔的螺纹孔21和安装孔22，支撑杆12可活动地穿过安装孔22，驱动轴30与螺纹孔21螺纹配合以驱动升降件20沿驱动轴30的轴向运动，进而带动镜头模组11运动。
优选地，驱动机构40为步进电机，驱动轴30可以是步进电机的输出轴，也可是与步进电机的输出轴进行固定连接，该步进电机即能控制镜头模组11的直线运动，又能控制镜头模组11的转动，因此，不需要安装两个或者多个去控制镜头模组11运动的不同阶段，可减小摄像装置100的空间占用率，有助于实现摄像装置100的小型化，并降低生产成本。
可以理解地，实际应用中，还可以在步进电机与驱动轴30之间增加一个减速箱，通过减速箱对步进电机的旋转输出进行降速增矩处理，以使驱动轴30可以获得更大的扭矩。
齿轮组50位于升降件20远离镜头模组11的一侧，齿轮组50包括第一齿轮51和用于与第一齿轮51啮合的第二齿轮52，第一齿轮51套设于驱动轴30外并可随驱动轴30一起旋转，第二齿轮52套设于支撑杆12外。
本实施例中，摄像装置100处于初始状态时，第一齿轮51与第二齿轮52并未啮合，且第二齿轮52到升降件20的距离大于第一齿轮51到升降件20的距离，只有当第二齿轮52随支撑杆12朝收容腔203外运动一定距离后，第二齿轮52才会与第一齿轮51啮合，继而驱动镜头模组11旋转。
当用户需要使用电子设备1的拍摄功能时，可以控制驱动机构40驱使驱动轴30转动，升降件20在驱动轴30的作用下朝向镜头模组11作直线运动，升降件20推动支撑杆12和镜头模组11一起作直线运动，并将镜头模组11从收容腔203内推出，直至第一齿轮51与第二齿轮52啮合，驱动机构40停止工作，用户即可正常使用电子设备1的拍摄功能；驱动机构40继续驱使驱动轴30旋转，升降件20继续朝向镜头模组11作直线运动，当第二齿轮52随支撑杆12运动至与第一齿轮51啮合时，驱动轴30通过第一齿轮51带动第二齿轮52旋转，第二齿轮52通过支撑杆12带动镜头模组11旋转，用户即可拍摄不同角度的图片，操作过程中不需要用户手动转动电子设备1，方便用户使用，提高了用户的操作体验。
拍摄完成后，可以控制驱动机构40驱使驱动轴30反向转动，升降件20朝向齿轮组50作直线运动，并带动支撑杆12和镜头模组11一起运动，最终将镜头模组11收回至收容腔203内，降低了镜头模组11暴露在外而被损坏的风险。
可以理解地，第一齿轮51与驱动轴30实现联动的方式可以是在二者接触的部位设置限位平面，通过限位平面的配合即可防止二者的相对转动，也可以是通过胶合或者机械固定的方式将二者固定在一起。可以理解地，第二齿轮52与支撑杆12之间的联动也可以通过上述方式实现，在此不再赘述。
请参阅图4与图5，作为本实施例一种改进方式，第一齿轮51沿驱动轴30的轴向开设有缺口53，缺口53用于供第二齿轮52嵌入以使第一齿轮51与第二齿轮52啮合，第一齿轮51在缺口53处不设置轮齿。
具体地，本实施例中，第一齿轮51包括套设于驱动轴30外的空心筒体511、凸设于空心筒体511外侧壁的第一轮齿部512、以及凸设于空心筒体511外侧壁的第二轮齿部513，第二轮齿部513的相对两侧分别与第一轮齿部512的相对两侧连接，从而围合形成一环形结构，第一轮齿部512和第二轮齿部513都从空心筒体511靠近升降件20的一侧朝远离升降件20的方向延伸，且第一轮齿部512的延伸长度大于第二轮齿部513的延伸长度，从而形成该缺口53，当第二齿轮52运动至第一齿轮51处时，第二齿轮52可以轻松嵌入该缺口53，随着第一齿轮51的转动，第二齿轮52就会自动与第一轮齿部512啮合，然后再与第二轮齿部513啮合，方便第一齿轮51与第二齿轮52啮合。
请参阅图4，作为本实施例一种改进方式，第一齿轮51在驱动轴30轴向方向上的宽度大于第二齿轮52在支撑杆12轴向方向上的宽度。
当镜头模组11旋转时，第一齿轮51与第二齿轮52啮合，但此时升降件20仍然会作直线运动，因此会继续带动支撑杆12和第二齿轮52作直线运动，通过设置第一齿轮51的宽度大于第二齿轮52的宽度，可保证第一齿轮51在镜头模组11的旋转阶段始终与第二齿轮52保持啮合。
可以理解地，第二齿轮52的宽度并不局限于大于第一齿轮51，例如，相同或者小于也是可以的。
本实施例中，第一齿轮51与驱动轴30、以及第二齿轮52与支撑杆12都是单独成型后再组装在一起的。分体组装成型可以降低制造难度，便于生产。
可以理解地，第一齿轮51与驱动轴30、以及第二齿轮52与支撑杆12一体成型也是可以的。
作为本实施例一种改进方式，升降件20内设有与安装孔22连通的环形槽23，支撑杆12上凸设有插入环形槽23的凸起121。
通过环形槽23和凸起121的配合，升降件20朝向齿轮组50运动时，升降件20通过凸起121和环形槽23的配合带动支撑杆12一起运动，从而带动镜头模组11运动。
请参阅图4，作为本实施例一种改进方式，摄像装置100还包括位于齿轮组50与升降件20之间的固定支架60，固定支架60固定至背板201的内侧，并与驱动机构40相对固定，固定支架60贯穿设有与螺纹孔21正对的第一通孔61和与安装孔22正对的第二通孔62，驱动轴30可活动穿过第一通孔61，支撑杆12可活动穿过第二通孔62。
可以理解地，当固定支架60与升降件20之间的间距足够大时，将齿轮组50设置在固定支架60与升降件20之间也是可以的。
本实施例中，镜头模组11与支撑杆12优选为一体成型。这样可以保证摄像机构10的整体强度，提高电子设备1的可靠性。可以理解地，镜头模组11与支撑杆12分体组装成型也是可以的。
可以理解地，实际应用中，还可以额外设置一个用于引导升降件20运动的导向机构，例如，设置一个一端与固定支架60固定连接、另一端可活动插入升降件20的导向杆，这样，升降件20可以在导向杆的导向作用下进行运动，使其运行更平稳，也即，使镜头模组11运行更平稳。
请参阅图5-图8，下面对镜头模组11的推出、旋转、反转及收回过程进行详细描述。
电子设备1接收第一控制指令并向驱动机构40发送第一执行指令；
驱动机构40接收第一执行指令后驱使驱动轴30旋转，由于升降件20与驱动轴30螺纹配合，因此升降件20在驱动轴30的驱动下朝远离固定支架60的方向作直线运动，升降件20推动镜头模组11和支撑杆12一起运动，最终将镜头模组11经通口204从收容腔203内推出，升降件20在作直线运动的同时，会带动第二齿轮52一起运动，使第二齿轮52朝向第一齿轮51运动，并通过缺口53与第一齿轮51啮合；
镜头模组11被从收容腔203中推出且第一齿轮51与第二齿轮52啮合后，升降件20受驱动轴30的驱动继续朝远离固定支架60的方向作直线运动，升降件20继续推动镜头模组11和支撑杆12运动，但由于此时第一齿轮51已经与第二齿轮52啮合，因此，驱动轴30在旋转的同时会通过第一齿轮51带动第二齿轮52一起旋转，第二齿轮52带动支撑杆12旋转，从而带动镜头模组11旋转预设角度；
镜头模组11旋转预设角度后，电子设备1接收第二控制指令并向驱动机构40发送第二执行指令；
驱动机构40接收第二执行指令后驱使驱动轴30反向旋转，升降件20受驱动轴30的驱动朝向固定支架60作直线运动，升降件20通过凸起121和环形槽23的配合带动支撑杆12运动，支撑杆12带动镜头模组11和第二齿轮52一起运动，同时驱动轴30反向旋转时，会通过第一齿轮51带动第二齿轮52一起反向旋转，第二齿轮52通过支撑杆12带动镜头模组11反向旋转，直至第一齿轮51与第二齿轮52脱离啮合状态，镜头模组11停止转动；
第一齿轮51和第二齿轮52脱离啮合后，升降件20受驱动轴30的驱动继续朝向固定支架60作直线运动，升降件20通过凸起121和环形槽23的配合推动支撑杆12运动，支撑杆12带动镜头模组11和第二齿轮52一起运动，直至将镜头模组11收回至收容腔203内的初始位置。
以上所述的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
