下面结合附图和实施方式对本申请作进一步说明。
请参阅图1-图3，本实施例提供一种升降旋转机构，适用于驱动镜头组件400伸缩以及旋转，包括：
外壳110，外壳110具有容纳腔1144。
丝杆170，丝杆170可转动设置在容纳腔1144内。
驱动组件390，驱动组件390用于驱动丝杆170转动。
传动套筒120，传动套筒120套设在丝杆170的外周且传动套筒120的内壁与丝杆170螺纹连接，传动套筒120用于与镜头组件400连接。
旋转套筒150，旋转套筒150套设在传动套筒120的外周，且旋转套筒150的可转动设置在容纳腔1144内；传动套筒120的外周设有滑动部122，旋转套筒150的内壁设有导向部152，滑动部122可与导向部152沿轴向相对滑动且滑动部122可对导向部152传递扭矩，旋转套筒150或传动套筒120上设有用于对滑动部122与导向部152轴向相对滑动进行限位的限位部154。
移动螺母140，移动螺母140套设在旋转套筒150的外周，旋转套筒150的外周与移动螺母140螺纹连接；外壳110上还设有用于限制移动螺母140朝远离镜头组件400轴向运动的限位结构。
第一弹性元件130，第一弹性元件130的一端与移动螺母140靠近镜头组件400的一端抵接，第一弹性元件130的另一端设置在容纳腔1144内，第一弹性元件130预压设置于容纳腔1144内将移动螺母140抵接于限位结构。
具体地，以下采用升降旋转机构的推动镜头组件400升降及旋转的四种状态来对该升降旋转机构进行阐述。
镜头组件400上升状态：第一弹性元件130对移动螺母140施加一个背离镜头组件400方向的作用力，以使移动螺母140抵接固定在外壳110的限位结构上。由于移动螺母140在第一弹性元件130的作用下固定，与该移动螺母140螺纹连接的旋转套筒150固定，旋转套筒150对传动套筒120施加具有周向的约束力，以使传动套筒120与旋转套筒150之间仅具有沿丝杆170延伸方向上的自由度。当驱动组件390驱动丝杆170转动时，丝杆170使与其螺纹连接的传动套筒120在丝杆170上做直线运动，旋转套筒150上的导向部152对传动套筒120上的滑动部122进行导向，以使该传动套筒120带动镜头组件400上升。
镜头组件400旋转状态：当上述传动套筒120相对旋转套筒150滑动一定距离后，旋转套筒150或传动套筒120上的限位部154对滑动部122进行限位，以使得传动套筒120停止滑动。此时，驱动组件390继续带动丝杆170转动，由于传动套筒120不能继续上升，在传动套筒120第一螺纹的作用力下，传动套筒120与丝杆170同步转动。再者，该滑动部122对导向部152施加一扭矩，旋转套筒150随传动套筒120同步转动，旋转套筒150使得与其螺纹连接的移动螺母140克服第一弹性元件130的弹力朝镜头组件400方向做直线运动。该过程中，传动套筒120转动使得镜头组件400转动角度。
镜头组件400反向旋转状态：驱动组件390驱动丝杆170反向转动。丝杆170对传动套筒120施加有反向的扭力，即丝杆170对旋转套筒150施加有反向的扭力。此时，移动螺母140不再朝镜头组件400方向移动，且受到来自旋转套筒150背离镜头组件400方向的作用力，该移动螺母140在第一弹性元件130的作用下，该移动螺母140朝背离镜头组件400方向做直线运动。该过程中，旋转套筒150、传动套筒120随丝杆170同步转动，该传动套筒120使得镜头组件400反向旋转。
镜头组件400下降状态：当移动螺母140重新与外壳110上的限位结构抵接时，该镜头组件400回到初始转动位置。此时，移动螺母140无法继续朝背离镜头组件400方向移动，即移动螺母140与旋转套筒150无法传动，以使得旋转套筒150固定，传动套筒120与旋转套筒150之间仅具有沿丝杆170延伸方向上的自由度。驱动组件390继续驱动丝杆170反向转动，传动套筒120在丝杆170的作用下，传动套筒120的滑动部122在旋转套筒150的导向部152上朝背离镜头组件400方向滑动，传动套筒120使得镜头组件400下降。
采用上述提供的升降旋转机构，通过外壳110、丝杆170、驱动组件390、传动套筒120、旋转套筒150、移动螺母140以及第一弹性元件130的配合，实现驱动镜头组件400伸缩以及旋转。且该结构中，仅设有一个驱动组件390，整体结构紧凑，占用空间较少。
为了便于该丝杆170转动，该丝杆170的与驱动组件390连接的一端设有滚动轴承180。优选地，该滚动轴承180为深沟球轴承。
需要补充的是，上述实施例提供的升降旋转机构适用于但不仅限于手机、平板、音响、无人机等电子设备。
可选地，第一弹性元件130为螺旋弹簧，该螺旋弹簧套设在旋转套筒150上。
请参阅图4，在本实施例中，滑动部122朝外凸起形成滑块，导向部152朝内凹陷形成导向槽，滑块与导向槽适配。导向槽朝外凸起形成限位部154。当然，在本实施例中，可在旋转套筒150上设置挡块即限位部154，当传动套筒120接触到挡块后，传动套筒120停止滑动。
在另一钟实施例中，滑动部122朝内凹陷形成有滑动槽，导向部152朝外凸起形成有导向轨，该滑动槽与该导向轨适配。另外该导向轨朝外凸起形成限位部154。当然，在本实施例中，可在旋转套筒150上设置挡块即限位部154，当传动套筒120接触到挡块后，传动套筒120停止滑动。
为了有效地支撑丝杆170，丝杆170远离镜头组件400的一端与驱动组件390传动连接，丝杆170靠近镜头组件400的一端环设有支撑件160，支撑件160与传动套筒120的内壁抵接。可以理解的是，在传动套筒120升降的过程中，支撑件160与传动套筒120的内壁发生相对摩擦。因此，支撑件160选择耐磨的材料。优选地，该支撑件160由聚四氟乙烯制成。
进一步地，外壳110包括具有容纳腔1144的壳体114、盖设在壳体114一侧的第一安装件112以及盖设在壳体114另一侧的第二安装件116。第一安装件112与旋转套筒150靠近镜头组件400的一端抵接，第二安装件116与旋转套筒150远离镜头组件400的一端抵接。
再者，第二安装件朝容纳腔1144凸起形成限位面1162，即限位结构，该限位面1162用于与移动螺母140抵接。
另外，请参阅图5，壳体114的内壁朝内凹陷形成有凹槽1142，移动螺母140的外周朝外凸起形成凸块142，该凸块142与该凹槽1142适配，该凹槽1142用于对凸块142进行导向。
在本实施例中，传动套筒120与镜头组件400之间还连接有缓冲机构。该缓冲机构的设置，可减少镜头组件400受到的损害。
具体地，缓冲机构包括与传动套筒120连接且中空设置有螺纹的连接件230、一端与连接件230螺纹连接且另一端与镜头组件400固定连接的固定件210以及套设在固定件210上且两端分别与连接件230以及固定件210抵接的第二弹性元件220。在传动套筒120转动时，该传动套筒120驱动连接件230转动，连接件230带动与其螺纹连接的固定件210转动，并在第二弹性元件220的作用下，连接件230与固定件210之间仅发生轻微的滑动。这种结构，有利于对镜头组件400受到碰撞或其他振动时进行缓冲，减少镜头组件400受到伤害。
进一步地，在本实施例中，连接件230与传动套筒120通过销轴240连接。
在本实施例中，驱动组件390与丝杆170之间还设有用于降低驱动组件390输出转速的减速机构。如此，可增大驱动丝杆170转动的扭矩且实现更为精准的控制。
具体地，减速机构包括第一传动件380、第一主动齿轮370、多个第一从动齿轮360、第二传动件350、第二主动齿轮340、多个第二从动齿轮330以及第三传动件320；第一传动件380与驱动组件390的输出轴传动连接，第一主动齿轮370与第一传动件380传动连接，多个第一从动齿轮360均匀环设在第一主动齿轮370的外周且第一从动齿轮360与第一主动齿轮370啮合，多个第一从动齿轮360皆与第二传动件350传动连接，第二主动齿轮340与第二传动件350传动连接，多个第二从动齿轮330环设在第二主动齿轮340的外周且第二从动齿轮330与第二主动齿轮340啮合，多个第二从动齿轮330皆与第三传动件320传动连接，第三传动件320与丝杆170传动连接。
上述减速机构中，驱动组件390的输出轴驱动第一传动件380转动，继而带动至与其连接的第一主动齿轮370，第一主动齿轮370带动与其啮合的多个第一从动齿轮360转动，多个第一从动齿轮360带动与其连接的第二传动件350转动，第二传动件350带动与其连接的第二主动齿轮340转动，第二主动齿轮340再带动与其啮合的第二从动齿轮330转动，接着第二从动齿轮330带动与其连接的第三传动件320转动，最后第三传动件320将驱动组件390输出的扭矩传递至丝杆170。
另外，该减速机构中，第一从动齿轮360的齿数大于第一主动齿轮370的齿数，第二从动齿轮330的齿数大于第二主动齿轮340的齿数，这样，通过两级减速以大幅度降低驱动组件390输出的转速，以及大幅度增加扭矩。
可选地，该驱动组件390包括有转动电机。优选地，该转动电机为伺服电机。
再者，该减速机构还包括安装座310，上述部件皆设置在安装座310内。另外，安装座310的内壁上设有与第一从动齿轮360以及第二从动齿轮330啮合的齿。
为了解决上述问题，本实施例还提供一种便携式电子装置，包括镜头组件400以及如上述的升降旋转机构。
采用上述提供的便携式电子装置，可实现驱动镜头组件400伸缩以及旋转。且升降旋转机构中，仅设有一个驱动组件390，整体结构紧凑，占用空间较少，可节约便携式电子装置壳体114的内部空间。
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。
