请一并参阅图1和图2，现对本发明实施例提供的手机摄像头伸缩装置100进行说明。手机摄像头伸缩装置100，包括驱动装置1、换向齿轮机构2、用于带动手机摄像头伸出或缩回的连接机构3、控制模块以及壳体4，驱动装置1、换向齿轮机构2、连接机构3以及控制模块均设于壳体4内，控制模块与驱动装置1电性连接且可控制驱动装置1正转或反转；换向齿轮机构2包括枢接转动于壳体4上的第一传动齿轮21、第一行星齿轮22、第二行星齿轮23以及行星架24，第一传动齿轮21包括由驱动装置1驱动转动的主齿轮211以及设于主齿轮211上且与主齿轮同轴转动的副齿轮212，行星架24通过转轴枢接于副齿轮212，第一行星齿轮22枢接于行星架24上且与副齿轮212啮合，第二行星齿轮23枢接于行星架24上且与副齿轮212啮合；连接机构3包括与第一行星齿轮22啮合或与第二行星齿轮23啮合的第二传动齿轮31以及用于固定手机摄像头的齿条件32，第二传动齿轮31枢接转动于壳体4内，齿条件32活动连接于壳体4内且与第二传动齿轮31啮合时相对壳体4伸出或收缩，第一行星齿轮22于驱动装置1正转驱动主齿轮211时与第二传动齿轮31接触且啮合传动以使齿条件32相对壳体4伸出，第二行星齿轮23于驱动装置1反转驱动主齿轮211时与第二传动齿轮31接触且啮合传动以使齿条件32相对壳体4缩回。
本发明实施例提供的手机摄像头伸缩装置100，通过控制模块控制驱动装置1正向转动时，驱动装置1带动主齿轮211正向转动，进而第一行星齿轮22与主齿轮211同轴转动的副齿轮212啮合转动，此时，第一行星齿轮22绕于副齿轮212的中轴线转动直至与第二传动齿轮31接触，第一行星齿轮22 与第二传动齿轮31啮合传动，使得第二传动齿轮31绕于其中轴线相对壳体4作周向转动，并且与齿条件32啮合传动，齿条件32则相对壳体4作直线上升运动，使与齿条件32固定连接的手机摄像头伸出，当控制模块控制驱动装置1反向转动时，驱动装置1带动主齿轮211反向转动，进而第二行星齿轮23与主齿轮211同轴转动的副齿轮212啮合转动，此时，第二行星齿轮23绕于副齿轮212的中轴线转动直至与第二传动齿轮31接触，第二行星齿轮23与第二传动齿轮31 啮合传动，使得第二传动齿轮31绕于其中轴线相对壳体4作周向转动，并且与齿条件32啮合传动，齿条件32则相对壳体4作直线下降运动，使与齿条件32固定连接的手机摄像头伸出缩回，整个过程通过控制模块实现自动控制，使手机摄像头平稳地、快速地完成自动伸出或者缩回，操作方便、实用。
进一步地，请参阅图1和图2，在本实施例中，行星架24为三角形行星架，第一行星齿轮22与第二齿轮23分别枢接于三角形行星架上的两个对角上。当第一行星齿轮22啮合传动第二传动齿轮31时，第二行星齿轮23脱离与副齿轮212的啮合，此时，齿条件32相对壳体4作直线下降运动。或者当第二行星齿轮啮合23传动第二传动齿轮31时，第一行星齿轮22脱离与副齿轮212的啮合，此时，齿条件32则相对壳体4作直线下降运动。由于第一行星齿轮22和第二行星齿轮23的直径均大于副齿轮212与第二传动齿轮31之间的间隙，第一行星齿轮22或者第二行星齿轮23在与第二传动齿轮31啮合传动时，只发生自转运动，不发生公转运动，这样可以更加稳定地、匀速地传递动力来驱动第二传动齿轮31，使手机摄像头随齿条件32平稳的伸出或者缩回。
进一步地，请参阅图1和图2，在本实施例中，换向齿轮机构2还包括用于限位行星架24以使第一行星齿轮22和第二行星齿轮23均与第二传动齿轮31处于非接触状态的扭簧件25，扭簧件25的一端连接于行星架24，扭簧件25的另一端连接于壳体4，在行星架24随第一行星齿轮22或者第二行星齿轮23转动后，使扭簧件25具有张力，停止工作后，在扭簧件25张力的作用下，行星架24恢复到原位，第一行星齿轮22或者第二行星齿轮23也恢复到原位，保证第一行星齿轮22和第二行星齿轮23在非工作状态下处于与第二传动齿轮31分离的状态，使手机摄像头在伸出状态时，可以手动推动手机摄像头恢复到原位。
进一步地，请参阅图1和图2，在本实施例中，第二传动齿轮31包括第一子齿轮311以及设于第一子齿轮311上且与第一子齿轮311同轴转动的第二子齿轮312，第一子齿轮311与第一行星22齿轮啮合连接或与第二行星23齿轮啮合连接，第二子齿轮312与齿条件32啮合连接，相比于第一子齿轮311，第一行星齿轮22和第二行星齿轮23相比于第一子齿轮311直径较小，啮合传动第一子齿轮311时，降低了第一子齿轮311的转动速度，使齿条件32传动手机摄像头的速度减缓，从而使手机摄像头平稳地伸出或者缩回。
进一步地，请参阅图1和图2，在本实施例中，齿条件32包括与第二子齿轮312啮合连接的齿条主体321，齿条主体321上设有用于固定手机摄像头的固定部322，齿条主体321与第二子齿轮312啮合连接，同时，固定部322与手机摄像头固定连接带动手机摄像头伸出或者缩回，固定部322设于齿条件32上且固定连接手机摄像头，增强了齿条件32与手机摄像头的连接强度，保证手机摄像头顺利完成伸出或者缩回动作。
进一步地，请参阅图1和图2，在本实施例中，连接机构3还包括多个并排设置于壳体4内的导向件33，各导向件33均枢接于壳体4上且抵靠于齿条件32，齿条件32在第二传动齿轮31驱动下做直线运动，设置导向件33使齿条件32精确地带动手机摄像头伸出或者缩回，避免与壳体4发生摩擦、磕碰，而且齿条件32为长条状，运动时会产生一定的弯矩，导致带动手机摄像头伸出或者缩回有一定的误差，这里设置的导向件33也起支撑作用，保证手机摄像头精确移动。
进一步地，请参阅图1和图2，在本实施例中，驱动装置1包括电机11、与电机11主轴相连接的蜗杆12以及与蜗杆啮合传动的第三传动齿轮13，第三传动齿轮13与主齿轮211啮合传动，由电机11作为动力来源，在电机11的主轴上连接蜗杆12，蜗杆12可实现大扭矩传递，而且传递平稳、结构紧凑，由第三传动齿轮13传递动力至主齿轮211，降低转动速度，使传动过程更加平稳，传动更加精确。
进一步地，请参阅图1和图2，在本实施例中，第三传动齿轮13包括第一副齿轮131以及设有第一副齿轮131上且与第一副齿轮131同轴转动的第二副齿轮132，第一副齿轮131与蜗杆12啮合传动，第二副齿轮132与主齿轮211啮合传动，第一副齿轮131的齿轮直径大于第二副齿轮132的齿轮直径。第二副齿轮132与主齿轮211啮合连接，主齿轮211的齿轮直径大于第二副齿轮132的齿轮直径，使主齿轮211传动速度降低，进而使后续的传动机构稳定传动，使手机摄像头的稳定地伸出或者缩回。
进一步地，请参阅图1和图2，在本实施例中，第一副齿轮131为斜齿第一副齿轮，斜齿齿轮啮合度高、传动效率高且传动平稳，可有效的减小驱动装置1的噪声，增强手机摄像头伸缩装置100的实用性，第二子齿轮312可以选为直齿齿轮，直齿齿轮安装调试方便且安装精度高，满足手机摄像头精确移动的需要。
图中未示，本发明实施例还提供一种手机，手机包括上述的手机摄像头伸缩装置100。
本发明实施例提供的手机，采用了上述的手机摄像头伸缩装置100，因此手机实现了摄像头的自动伸缩功能，增强了手机的实用性，使手机智能化程度更高。
以上仅为本发明的优选实施例而已，并不用于限制本发明。对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
