具体地，参照图2-5所示，第二驱动组件600安装于第二连接座900上以用于驱动第一连接座100带动镜头模组200沿图3所示的Q方向转动，Q方向为第二方向（即：绕第二旋转中心轴N）转动的方向，第二检测组件700用于检测镜头模组200绕第二方向转动（绕第二旋转中心轴N转动）的位置信息，第一旋转中心轴M与第二旋转中心轴N相互垂直。第一连接座100安装于第二驱动组件600的输出端。第三连接座500与第二连接座900固定连接。第二驱动组件600运行时，第一连接座100绕第二旋转中心轴N转动，镜头模组200会随着第一连接座100一起转动。
具体地，参照图4、图5、图11和图12所示，第二检测组件700包括第二电路板710、第二电阻条720和第二导电件730。本实施例中，第二导电件730安装于第二驱动组件600上且能由第二驱动组件600驱动并随镜头模组200转动，第二电路板710安装于第二连接座900上且在镜头模组200转动时相对固定支架1200静止；第二电阻条720安装于第二电路板710之朝向第二导电件730的一侧，第二导电件730包括与第二驱动组件600连接的第二固定部731和从第二固定部731延伸抵接第二电阻条720的第二弹性接触部732。第二弹性接触部732与第二电阻条720形成与第二电路板710电连接的第二滑动变阻器，第二滑动变阻器的输出电阻值与镜头模组200的所述移动位置信息对应.当然了，具体应用中，作为替代的实施方案，也可将第二电路板710安装于第二驱动组件600上且能由第二驱动组件600驱动并随镜头模组200转动，第二导电件730安装于第二连接座900上且在镜头模组200转动时相对固定支架1200静止，即只要满足第二电路板710和第二导电件730中的一者安装于第二驱动组件600上且能由第二驱动组件600驱动转动、另一者安装于第二连接座900上，即可实现摄像镜头绕第二旋转中心轴N转动时第二电阻条720与第二导电件730的相对滑动。

具体地，第二开口7311与第二弹性接触部732一一对应设置，两个第二弹性接触部732分别设于两个第二开口7311内。两个第二弹性接触部732优选从两个第二开口7311反向延伸。本实施例中，第二导电件730为一体制造成型的部件，可省去分体制造后续的组装工序。
当然了，对于具有两个第二弹性接触部732的第二导电件730，其设置方案不限于上述方案，例如，作为上述第二导电件730一种替代的实施方案，可将第二导电件730设置为两个独立的部件分体制造成型后再组装连接，即：第二固定部731包括两个分体成型且相互连接的第二分体结构，每个第二分体结构分别设有一个第二开口7311，两个第二弹性接触部732分别一一设于两个第二开口7311内。
又或者，作为上述第二导电件730另一种替代的实施方案，可将第二导电件730设置为一体制造成型的部件，但第二开口7311只设置一个，两个第二弹性接触部732间隔设于同一个第二开口7311内，即：第二固定部731包括具有一个第二开口7311的一体成型结构，两个第二弹性接触部732间隔并排设于第二开口7311内。

具体地，参照图1、图3和图13所示，外壳800具有中空内腔810和从外壳800之外侧壁贯穿连通中空内腔810的摄像避让孔820，镜头模组200收容于中空内腔810内。摄像避让孔820可为腰型孔或者椭圆形孔或者矩形孔等。外壳800的设置，主要用于防护镜头模组200。
具体地，参照图1、图3和图13所示，第二连接座900与第三连接座500连接。第三驱动组件1100用于驱动第二连接座900带动第三连接座500和镜头模组200沿第三方向X往复直线移动，以使镜头模组200移动至与摄像避让孔820呈对位设置的位置或者移动至与摄像避让孔820呈错位设置的位置，第三方向X与第二旋转中心轴N平行、并与第一旋转中心轴M垂直。定义外壳800远离第三驱动组件1100的端部为外壳800底端，本实施例中，镜头模组200沿第三方向X往复直线移动包括朝靠近外壳800底端的方向直线移动和朝远离外壳800底端的方向直线移动。
参照图1、图2、图3和图14所示，第三驱动组件1100包括安装于固定支架1200上的第三电机1110和传动连接于第三电机1110与第二连接座900之间的丝杆传动机构1120。第三电机1110为可正反转的电机，且第三电机1110为减速电机，即第三电机1110为电机与齿轮减速器的集成体。
参照图1、图2、图3和图14所示，本实施例中，丝杆传动机构1120包括丝杆1121、丝杆座1122、连接杆1123、导杆1124、连接块1125，丝杆1121、连接杆1123和导杆1124依次间隔并排设置，丝杆1121的两端和导杆1124的两端都可转动地安装于固定支架1200上，且丝杆1121的一端与第三电机1110的输出端连接。第三方向X与丝杆1121平行,第三方向X即为丝杆座1122沿丝杆1121往复直线运动的方向; 第二方向平行于丝杆1121。丝杆座1122与丝杆1121配合，且与连接杆1123固定连接、与导杆1124滑动连接。连接杆1123的一端与连接块1125连接，第二连接座900与连接块1125连接。第三电机1110启动运行时，丝杆1121转动，丝杆座1122沿着丝杆1121和导杆1124直线移动，连接杆1123随丝杆座1122直线移动，连接块1125和第二连接座900在连接杆1123的带动下做直线运动，第二连接座900的直线运动会带动第三连接座500以及安装于第三连接座500上的各部件做直线运动，从而实现驱动镜头模组200直线运动，进而可驱动镜头模组200通过摄像避让孔820外露或者收藏于外壳800内。导杆1124的设置，主要用于提高丝杆座1122直线运动的平稳性。
本实施例提供的摄像装置10，工作原理是：当需要进行摄像时，控制第三驱动组件1100启动，驱动镜头模组200直线运动，运动至与摄像避让孔820对位的位置，以使得镜头模组200外露，从而使得镜头模组200可以对外摄像。当需要实现镜头模组200的俯仰旋转（即绕第一旋转中心轴M转动）功能时，控制第一驱动组件300启动，驱动第一连接座100带动镜头模组200向上翻转或者向下翻转，此时，第一电阻条420相对第一导电件430滑动，引起第一电阻条420输出阻值的变化，从而实现镜头模组200位置的实时监测。当需要实现镜头模组200的水平旋转（即绕第二旋转中心轴N转动）功能时，控制第二驱动组件600启动，驱动镜头模组200进行水平转动，此时，第二电阻条720相对第二导电件730滑动，引起第二电阻条720输出阻值的变化，从而实现镜头模组200位置的实时监测。
本实施例提供的摄像装置10，可应用于云台摄像设备或者其它需要位置检测功能的摄像设备上。
实施例二
本实施例提供的摄像装置10，与实施例一的区别主要在于，第一电阻条420和第一弹性接触部432的数量不同。具体地，本实施例中，第一电阻条420和第一弹性接触部432都设有一个，第一检测组件400还包括连接于第一固定部431与第一电路板410之间的第一引线450，单个第一弹性接触部432与第一电阻条420电接触。第一导电件430和第一电阻条420通过第一电路板410和第一连接引线440可连接形成一个如图16所示变阻器的检测电路，在第一电阻条420相对第一导电件430相对滑动时，第一电阻条420输出阻值会随之改变。本实施方案中，第一弹性接触部432为弹片，此处，采用单弹片的设置方案，需额外从弹片端引线，系统稳定可靠性比实施例一略差。
以上所述的仅是本实用新型的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本实用新型创造构思的前提下，还可以做出改进，但这些均属于本实用新型的保护范围。
