家电和电子设备上的摄像头通常固定设置在设有屏幕一面的边框上，随着全面屏的应用发展，家电和电子设备上开始配置了能够升降的摄像头，但该摄像头的摄像角度无法自动调节。

实施例1
如图1所示，本实施例提供一种可旋转升降摄像头1，可单独进行使用，也适用于配置有摄像头的装置，该可旋转升降摄像头1能够分段进行升降和旋转，还适用于配置有隐藏式摄像头的显示屏上，它包括摄像头模组10 和驱动组件20。
请一并参阅图2，驱动组件20包括驱动件21、传动件22、执行件23、锁定件24和限定件25，驱动件21通过传动件22能够驱动执行件23做与驱动件21的转轴平行的往复直线运动。摄像头模组10设于执行件23上，执行件23与限定件25之间形成非回转滑动配合段和可回转配合段。执行件23与限定件25处于非回转滑动配合段时，驱动件21通过传动件22能够驱动执行件23做往复直线运动。执行件23与限定件25处于可回转配合段时，锁定件24将传动件22与执行件23之间的相对转动锁定，以使得驱动件21驱动摄像头模组10转动。
上述，锁定件24、限定件25相当于是一种限制部件，限定件25通过与执行件23的配合限制执行件23的转动，也就是限制摄像头模组10的转动，锁定件24通过锁定传动件22与执行件23的相对转动从而限制执行件23的移动，也就是限制摄像头模组10的移动。当限定件25对执行件23的回转进行限制时，执行件23能够相对传动件22转动，从而使得执行件23也就是摄像头模组10能够在限定件25上滑动升降；当限定件25解除了对执行件23回转动作的限制时，锁定件24对执行件23和传动件22之间的相对转动进行限制，从而使得执行件23也就是摄像头模组10能够单独进行转动，进而使得摄像头模组10能够单独进行升降或旋转。
其中，摄像头模组10是一种视频、图像输入设备，它包括外壳、镜头、感光部件、滤光片、集成电路以及连接器等部件，根据可旋转升降摄像头1的不同应用选用不同类型的摄像头模组10，摄像头模组10可以采用现有的标准规格的模组，在此不赘述。
驱动组件20是一种能够独立进行往复直线动作或旋转动作的组件，其动作以执行件23体现，摄像头模组10设于执行件23上，与执行件23做相同且同步的动作。
驱动件21可以为旋转电机，在摄像头组件的体积较大时，驱动件21可以选用回转气缸、液压马达等旋转动力部件。
驱动件21带动传动件22转动，传动件22输入转动运动，通过传动件22与执行件23的配合，使得执行件23输出的动作为执行运动，因此传动件22和执行件23形成了一种变旋转运动为直线运动的机构，且直线运动方向与旋转运动的轴线平行。
传动件22还可以采用齿轮副结构，采用伞齿轮切换传动轴、采用齿轮齿条结构进行直线驱动，在该传动结构下的执行件23做的旋转运动为偏心旋转，限定件25和锁定件24是齿轮副中的齿轮，通过齿轮之间的离合达到直线运动和旋转运动的切换。
本实施例中，传动件22与执行件23之间形成螺纹配合，驱动件21驱动传动件22转动，执行件23相对传动件22做往复直线运动。传动件22和执行件23的螺纹配合能够使得执行件23做与旋转运动的转轴重合的直线运动，一方面使得驱动组件20的结构更加紧凑，另一方面使得摄像头模组10在旋转时能够沿一个轴同心转动，优化旋转摄像效果。
如图3所示，执行件23与限定件25之间形成滑块231、滑槽250配合，滑槽250包括条形槽段251和弧形槽段252，滑块231在条形槽段251时，执行件23与限定件25处于非回转滑动配合段，滑块231在所述弧形槽段252时，执行件23与限定件25处于可回转配合段。
进一步地，传动件22为螺杆，执行件23为与螺杆相配合的螺母，螺母呈套筒状，或者是套筒的内径局部设有内螺纹成为螺母，从而缩短传动件22和执行件23的螺接长度，减小驱动件21的驱动力，减小执行件23与传动件22之间卡死的概率。
限定件25是一种套筒，套设于执行件23之间，滑块231为设于执行件23表面的凸台，限定件25的内壁上设有滑槽250，条形槽段251为与滑 块231相配合凹槽，当滑块231嵌设于条形槽段251中时，执行件23不能相对限定件25转动，进而使得传动件22转动时，执行件23能够移动；弧形槽段252为自执行件23的端面打入的弧形槽，从而使得执行件23在限定件25中有一定的转动余量，使得传动件22可以带动执行件23转动。
弧形槽段252的槽的弧度决定了执行件23的转动角度，可以通过设置槽的弧度对摄像头模组10的转动范围进行限定。
条形槽段251与弧形槽段252之间至少一边通过斜面过渡。条形槽段251和弧形槽段252除了具有槽底面以外，还具有两个侧边，由于条形槽段251和弧形槽段252是连通的，因此，弧形槽段252与条形槽段251的两边均应是相连的。通过弧形槽段252与条形槽段251之间的斜面过渡能够使得执行件23的凸台顺畅地有弧形槽段252滑动至条形槽段251中，有效地防止执行件23与限定件25发生卡死的情况发生。
本实施例中，弧形槽段252的一个侧边通过斜面过渡至条形槽段251的侧边，另一边通过直角台阶过渡到条形槽段251的另一个侧边，摄像头模组10的缩回均是在执行件23上的滑块231转动至斜边过渡一侧边后，滑入条形槽段251中。
条形槽段251的两个侧边的中心面与弧形槽段252的两个侧边的中心面重合，从而使得执行件23在转动时，顺时针可转动角度和逆时针可转动角度相同，本实施例中，条形槽段251的弧度为90°，也就是摄像头模组10的转动范围为90°，其能够在-45°～45°之间转动。当然，该角度还可以按需设置成其他。
需要说明的是，弧形槽段252的槽可以是环形凹槽，也就是不限制执行件23的转动角度，进而使得摄像头模组10能够360°转动，还可以不设置弧形槽段252，使得执行件23上的滑块231完全在限定件25上伸出，从而不受到限定件25对于执行件23的转动的限定。
请一并参阅图4和图5，本实施例中，锁定件24为设于螺杆上的摩擦片，当执行件23与限定件25形成可回转配合时，摩擦片夹设于螺杆与螺母之间，通过增加螺杆与螺母之间的摩擦力的方式，将螺杆与螺母的相对转动锁定，进而使得螺杆带动螺母一同转动。
进一步地，螺杆上设有环形凹槽，摩擦片可以呈片状，螺杆上设有凹槽，摩擦片设于其中，从而夹设于螺杆与螺母之间。当然，摩擦片还可以呈环状且套设于环形凹槽上，摩擦片的外径与螺母的螺纹孔的小径相配合，从而能够夹设在螺母与螺杆之间。
为了使得锁定件24能够更容易的夹紧在螺杆与螺母之间，且具有较大的夹紧面积，提高螺杆与螺母锁定的可靠度，还可以在锁定件24上设置导向部241，导向部241为在锁定件24上设置锥面/斜面，使得摩擦片在于螺母接合时，二者之间逐渐由间隙配合过渡至过盈配合实现夹紧。
当然，为了防止摩擦片与螺母卡死，同样可以在摩擦片退出一端设置导向部241，也就是在摩擦片的进入和退出端均设置导向部241，使得摩擦片与螺母的接合和分离更加顺畅。
摩擦片可以选用较螺母质软的材质制成的部件，如铜、塑胶等，本实施例的摩擦片选用尼龙制成，尼龙具有较好的耐磨性，能够在多次摩擦后仍保有较好的夹紧效果。
传动件22或执行件23上设有限位部221，执行件23和传动件22之间通过限位部221接触时，执行件23在传动件22上的运动位置到达极限位置，极限位置即为上升的极限和下降的极限。限位部221用于限制传动件22和执行件23之间的相对移动位置，防止执行件23脱离传动件22，限制执行件23的升降位置。
本实施例中，传动件22上设有限位部221，该限位部221用于限制执行件23上升的极限位置，为了使得驱动组件20结构更加紧凑，执行件23 下降的极限位置由限定件25的端盖进行限定。
传动件22为螺杆时，其上的限位部221可以为设于螺杆的端部的凸台，螺母的光孔段与凸台相配合，且光孔段的孔径大于螺母的螺纹孔的孔径，当传动件22与执行件23运动到凸台与螺纹孔和光孔的抬肩抵接时，对执行件23的继续上升形成限位。当执行件23下降到执行件23的端面与限定件25的端盖抵接时，限定件25的端盖限制执行件23继续下降。
执行件23，也就是摄像头模组10上升到极限位置时，锁定件24将传动件22与执行件23之间的相对转动锁定。如此，使得执行件23也就是摄像头模组10能够在上升到极限位置后进行转动，升降与转动的动作的独立性更好，有效地避免了当锁定件24锁定不可靠时，传动件22与执行件23之间发生相对运动。
本实施例中，可旋转升降摄像头1还包括底座30，驱动件21通过支架固定在底座30上，限定件25连接在底座30上进行固定。驱动件21与传动件22之间还设置有减速机构40，进一步地，该减速机构40为齿轮减速机构40，通过调节齿轮的传动比，达到不同的传动效果，通过设置齿轮减速机构40增大了驱动件21的输出扭力，降低了驱动件21的输出转速，进而降低了其转动角度对于旋转驱动的角度精度的影响，使得驱动件21的动力更加强劲，角度输出精度更高。
上述，驱动件21在驱动摄像头模组10升降时，其转动为连续的转动，上升和下降的转动方向相反，当驱动件21驱动摄像头模组10转动时，摄像头模组10的转动与驱动件21的转动同步且相同，若摄像头模组10要往复转动，驱动件21也需要往复转动，其转动角度可以通过预先设定好的程序进行自动控制，也可以通过设置传感装置对摄像头模组10的位置进行感测，从而实现对驱动件21的控制。
本实施例中，可旋转升降摄像头1还包括控制器50、传感器60和感应 件70。控制器50分别与传感器60和驱动件21电性连接，感应件70设于执行件23上，感应件70能够随着执行件23一同转动，传感器60通过感应件70感测执行件23的转动角度，控制器50根据传感器60所感测的转动角度控制驱动件21动作。也就是当传感器60感测到执行件23转动到与弧形槽段252的侧边接合时，反馈给控制器50，控制器50控制驱动件21反向转动，从而实现对摄像头模组10的往复旋转的自动化控制。
进一步地，感应件70与执行件23之间形成可滑动的非回转配合。执行件23呈套筒状，且其表面设有滑块231，感应件70呈环状且可转动地嵌设在底座30上，套设于执行件23外且其上设有与滑块231相配合的凹槽，感应件70能够同执行件23一同转动但不同其一同移动，进而使得执行件23的转动角度也就是摄像头模组10的转角能够通过感应件70的转角体现。
传感器60可以为红外线传感器60，当执行件23转动到限定件25的弧形槽段252的侧边时，带动感应件70将传感器60发出的红外线挡住，从而判断此时执行件23转动到弧形槽段252的极限位置，控制器50可以向驱动件21发出换向或停止转动的信号。
在其他的实施例中，传感器60还可以为3D霍尔元件，感应件70为与3D霍尔元件配套使用的元器件，从而使得传感器60感测执行件23的转动角度，进而判断摄像头组件的转动角度。
可旋转升降摄像头1还包括线保护盖80，由于感应件70呈片状，容易将摄像头模组10的线缆割伤，将线保护盖80设于限定件25和感应件70之上，对感应件70进行隔挡，对线缆形成保护。
上述，摄像头模组10上升原理为：驱动件21转动，一同带动传动件22转动，执行件23的滑块231处于限定件25的条形槽段251中被限定了转动，执行件23带动摄像头模组10向上运动。驱动件21继续转动，执行件23继续上升，锁定件24逐渐夹设在传动件22与执行件23之间，当执 行件23与传动件22的限位部221抵接，执行件23运动到上升极限位置，锁定件24完全加紧在执行件23与传动件22之间，执行件23的滑块231处于限定件25的弧形槽段252中，驱动件21停止转动。
摄像头模组10旋转原理：当摄像头模组10上升到极限位置后，驱动件21转动，带动传动件22转动，传动件22通过锁定件24带动执行件23转动，进而使得通过控制驱动件21转动即能够控制摄像头模组10转动。摄像头模组10的转动角度范围由弧形槽段252的弧度确定，驱动件21的旋转角度可以预先通过弧形槽段252的弧度进行设定，也可以通过传感器60对于执行件23角度的反馈进行自动控制。
摄像头模组10的下降原理：驱动件21转动，该转动方向与上升时的转动方向相反，带动传动件22转动，传动件22通过锁定件24带动执行件23转动，使得执行件23的滑块231与弧形槽段252的侧边抵接，该侧边为具有斜面过渡一侧的侧边，执行件23无法继续转动。驱动件21继续带动传动件22转动，进而使得锁定件24与执行件23逐渐分离，执行件23通过斜面逐渐滑入至条形槽段251中。驱动件21继续带动传动件22转动，执行件23继续下降，当执行件23下降到执行件23的端面与限定件25的端盖抵接时，下降到极限位置，驱动件21停止转动。
实施例2
请一并参阅图6至图9，本实施例提供一种显示装置，包括显示屏2和实施例1中的可旋转升降摄像头1，可旋转升降摄像头1通过底座30固定在显示屏2上，摄像头模组10能够相对显示屏2伸出或缩入，且能够在显示屏2上伸出后进行转动。
由此，可旋转升降摄像头1是一种隐藏式摄像头，能够在伸出后进行转动，这种动作逻辑的设置对于显示装置的隐藏式摄像头非常适用，使得显示装置的摄像头能够隐藏在显示屏2之下/之后，又能够通过转动具有更 大的摄像角度。
在不使用摄像头时，摄像头模组10隐藏在内部，避免泄漏隐私，产品外观也更简洁。当需要使用摄像头时，摄像头模组10伸出，摄像头模组10的摄像靶面与显示屏2平行。当需要调整视角时，摄像头模组10可以左右旋转调整视角。
上述，显示屏2可以为手机屏、电脑屏、摄像机屏或电视屏等可以使用摄像头的家电和消费类电子产品的屏上。
本实施例的显示装置为电视机，显示屏2即为电视屏，可旋转升降摄像头1设于显示屏2之后，当摄像头模组10下降到极限位置后，摄像头模组10的顶部不高于显示屏2的顶面，从而达到隐藏的效果。
在这里示出和描述的所有示例中，任何具体值应被解释为仅仅是示例性的，而不是作为限制，因此，示例性实施例的其他示例可以具有不同的值。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步定义和解释。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本申请范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。
