背景技术
高屏占比终端设备由于具备良好的视觉体验，受到各大终端设备厂商的青睐。为了实现尽可能大的屏占比，相关技术中所使用的听筒往往采用激励器带动屏幕的方式来实现发声，而包括多个光学器件的光学模组需隐藏在终端设备的顶部区域，通过螺杆螺纹和滑块结构实现上下伸缩运动。但是相关技术中的螺杆螺纹和滑块结构中的挂钩在一侧施加力给光学模组时，会导致光学模组上下伸缩运动受力不均，容易出现卡死情况，同时螺杆螺纹和滑块结构整体所占空间比较大，导致出现堆叠空间紧张的问题。
图1为相关技术中的螺杆螺纹式上下伸缩光学模组在整机中的布局示意图。其中101为马达，用于提供旋转动力；102为减速箱，用于减速提高输出扭矩，同时减低负载的惯性；103为挂台，连接在带有光学模组的滑块模组107上，其中挂台103所施加的力作用在滑块模组107的一侧，因此会出现左右两侧受力不均的情况；104为螺杆螺纹结构，当马达101转动时，经过减速箱102输出更高的扭矩在螺杆螺纹结构104的Y方向上运动；105为丝杆，用于防止马达101、减速箱102以及挂台103左右转动；106为主板；108为压缩弹簧，用于保护滑块模组107在受到外界力作用后保持正常工作；109为聚甲醛树脂(Polyoxymethylene，POM)导向块，用于保证滑块模组107在Y方向更好地滑动，这里的Y方向为终端设备的长度方向。
如图2所示，马达101、减速箱102以及挂台103在螺杆螺纹结构104的带动下向上运动，挂台103在滑块模组107的一侧施加力带动滑块模组107 向上运动，由于滑块模组107左右两侧受力不均匀，会导致滑块模组107在运动过程中发生倾斜现象，容易出现卡死情况。同时螺杆螺纹结构104和滑块模组107所占整机空间比较大，导致堆叠空间较紧张。

在本公开实施例中，如图3所示，动力源包括主板控制器和马达模组12，马达模组12与主板控制器连接，在主板控制器的控制下调节转速和转动圈数；转盘11与马达模组12连接。
动力源包括主板控制器以及与主板控制器连接的马达模组12，其中主板控制器设置于主板结构上，通过主板控制器与马达模组12的连接，可以控制马达模组12的工作，同时可调节马达模组12的转速和转动圈数。转盘11与马达模组12连接，通过主板控制器控制马达模组12工作，进而可驱动与马达模组12连接的转盘11转动。
在本公开实施例中，马达模组12包括具有一安装孔的支撑体121，以及设置于安装孔内的、在主板控制器的控制下转动的旋转轴122；旋转轴122 的轴向长度大于安装孔的深度，旋转轴122突出于安装孔的部分、沿径向方向形成有凹槽1221。
马达模组12包括一支撑体121，在支撑体121上形成有一安装孔，这里形成的安装孔为贯穿支撑体121厚度方向的通孔，在安装孔内设置有一旋转轴122，旋转轴122连接至主板控制器，在主板控制器的控制下进行转动。
其中，旋转轴122的径向尺寸与安装孔相匹配，轴向长度大于安装孔的深度，使得旋转轴122的一端或者两端突出于支撑体121所在的端面。在旋转轴122突出于安装孔的一端、沿径向方向形成有凹槽1221，其中凹槽1221与支撑体121所在的端面可以有0.05-0.10mm的高度差，凹槽1221的数量至少为一个，可设置两个，且两个凹槽1221的连线与旋转轴122的一直径相平行。
在本公开实施例中，转盘11上设有一与旋转轴122配合的套孔112，套孔112的内壁上设置有与凹槽1221匹配的凸起1121。
在转盘11上形成一套孔112，通过将套孔112套设在旋转轴122突出于支撑体121所在端面的部分，使得套孔112与旋转轴122配合，实现转盘11与马达模组12的连接。
在套孔112的内壁上设置有与凹槽1221匹配的凸起1121，其中凸起1121的数量与凹槽1221的数量相同，且凸起1121的设置位置可以实现与凹槽1221的配合。在套孔112与旋转轴122配合时，套孔112内壁上所设置的凸起1121可以与旋转轴122上形成的凹槽1221卡接配合，保证套孔112与旋转轴122配合的牢固性。
在本公开实施例中，如图3和图6所示，转盘模组1还包括：将套孔112固定于旋转轴122上的连接结构13。
在套孔112内壁上所设置的凸起1121与旋转轴122上的凹槽1221卡接配合之后，旋转轴122可突出于转盘11，此时，可以利用连接结构13将套孔112固定于旋转轴122上，进而使得转盘11紧固在马达模组12的旋转轴122上，实现两者的紧固配合。
其中，连接结构13可以为螺丝，连接结构13将马达模组12的旋转轴122和转盘11紧固在一起后，转盘11和马达模组12的支撑体121之间可存 在间隙，因此转盘11依然可以在马达模组12的旋转轴122的带动下做旋转转动。
在本公开实施例中，马达模组12还包括：柔性电路板，旋转轴122通过柔性电路板和主板弹片，连接至主板控制器。
在马达模组12与主板控制器连接时，具体为马达模组12的旋转轴122通过柔性电路板连接至主板弹片，通过主板弹片与主板控制器的连接，实现旋转轴122与主板控制器的连接，进而可以通过主板控制器调节旋转轴122的转速和转动圈数。
其中主板弹片、主板控制器均设置于主板结构上。马达模组12的外壳可固定在主板结构的主板上盖上，即马达模组12通过外壳与主板上盖之间的连接，实现马达模组12与主板结构在形态上的固定。在马达模组12的外壳与主板上盖之间连接时，可以采用粘贴的形式，即如图6所示，可在马达模组12的外壳上贴双面胶7，通过双面胶7与马达模组12的外壳以及主板上盖的连接，实现将马达模组12的外壳固定在主板上盖上。
如图3至图5，下面对主板控制器、旋转轴122、转盘11、摆杆2以及被驱动件3之间的配合关系进行介绍，主板控制器与马达模组12的旋转轴122连接，控制旋转轴122转动，通过旋转轴122的转动带动转盘11转动，在转盘11转动的过程中，通过转盘11上的转盘柱111与摆杆2上滑轨23的配合，可以带动摆杆2运动。摆杆2的一端为齿轮部21，可以与被驱动件3上形成的齿条31配合；在摆杆2转动时，可以带动齿条31做上下往返运动，在齿条31做往返运动时，可以带动支架32做往返运动，进而可以保证电子器件的往返运动。
其中，在摆杆2转动时，摆杆2可以绕转轴24运动，转轴24可连接至机壳上，如连接至主板结构的主板上盖上。
下面对本公开实施例驱动系统的整个工作过程进行介绍，如图3以及图4所示，主板控制器通过主板弹片给马达模组12进行通电，使得包括马达模组12以及转盘11的转盘模组1沿着顺时针方向旋转，在转动的过程中，转盘11上所设置的转盘柱111带动摆杆2绕着转轴24做顺时针方向旋转；摆杆2上的齿轮部21给被驱动件3上的齿条31作用力，使得两者做相向运动， 被驱动件3在齿条31的带动作用下向上运动，从而完成电子器件向上伸出运动。当转盘模组1中转盘11上的转盘柱111从Y方向最高点旋转运动到Y方向最低点时，电子器件向上做伸出运动，这里的Y方向为终端设备的长度方向。
如图3以及图5所示，当转盘模组1继续顺时针旋转时，即转盘11上的转盘柱111从Y方向最低点旋转运动到Y方向最高点时，摆杆2绕着转轴24做逆时针方向旋转；摆杆2上的齿轮部21给被驱动件3上的齿条31作用力，使得两者做相向运动，被驱动件3在齿条31的带动作用下做向下运动，从而完成电子器件向下做缩回运动。
从图3、图4以及图5中可以看出，摆杆2上的齿轮部21所施加的力比较靠近被驱动件3的中间，电子器件在上下伸缩运动时，左右两侧所受作用力相对均匀，同时齿轮结构传动比较稳定，因此能够实现电子器件更稳定地上下伸缩运动。同时上述结构使得空间更紧凑，有利于堆叠空间布局。
在本公开实施例中，如图3和图4所示，驱动结构还包括：
与被驱动件3配合，且控制被驱动件3运动方向的导向块4；限制导向块4在第一方向上运动的导向固定块5，第一方向与被驱动件3的运动方向垂直；以及与被驱动件3配合的防水结构6。
导向块4可以为POM导向块，固定在主板上盖上，且沿终端设备的Y方向延伸，被驱动件3通过底部卡槽卡在导向块4上，此时的导向块4相当于一滑轨，在摆杆2上的齿轮部21给被驱动件3上的齿条31作用力时，被驱动件3可以沿着导向块4在Y方向上运动，进而可以使得导向块4控制被驱动件3的运动方向。
导向固定块5也固定在主板上盖上，通过导向固定块5与连接螺丝以及导向块4的配合，实现将导向块4限位在主板上盖上，这里的限位为终端设备厚度方向(Z方向)的限位。第一方向即为Z方向，与被驱动件3的运动方向所在的端面垂直。其中在Z方向上，导向块4、导向固定块5以及齿条31可依次排列设置，导向固定块5以及导向块4不会限制齿条31的上下运动。通过对导向块4在Z方向进行限位，也可以保证对被驱动件3在Z方向上的限位。其中导向固定块5可以位于被驱动件3的内部，图4中虽然示出 了导向固定块5，但仅仅用于说明导向固定块5与齿条31在Z方向上的空间位置关系，即导向固定块5不会限制齿条31的上下运动。
防水结构6可以为防水硅胶支架，通过防水结构6与被驱动件3的配合，可用于保证被驱动件3的防水，进而实现对电子器件的保护。
在本公开实施例中，电子器件为摄像头模组，通过被驱动件3的上下往返运动，可以实现摄像头模组的伸缩，进而可以在需要通过摄像头模组拍摄时控制被驱动件3向上运动，在不需使用摄像头模组时控制被驱动件3向下运动，实现摄像头模组的隐藏。通过防水结构6对被驱动件3的保护可以实现对摄像头模组的保护。
本公开实施例还提供一种终端设备，包括上述的驱动系统。摆杆2通过转轴24与机壳固定，摆杆2绕转轴24转动。上述的驱动系统，通过转盘模组的运动带动与转盘模组连接的摆杆进行转动，在摆杆转动的过程中带动与摆杆连接的被驱动件进行往返运动，可以实现通过摆杆与转盘模组的配合控制被驱动件更稳定地上下伸缩运动，同时上述结构设计可以使得空间更加紧凑，有利于堆叠空间的布局。
本说明书中的各个实施例均采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似的部分互相参见即可。
尽管已描述了本公开实施例的实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例做出另外的变更和修改。所以，所附权利要求意欲解释为包括本公开实施例以及落入本公开实施例范围的所有变更和修改。
最后，还需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者终端设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者终端设备所固有的要素。在没有更多限制的情况下，由语句“包括一 个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者终端设备中还存在另外的相同要素。
以上所述的是本公开的实施方式，应当指出对于本技术领域的普通人员来说，在不脱离本公开所述的原理前提下还可以作出若干改进和润饰，这些改进和润饰也在本公开的保护范围内。
