具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
请参见图2至5，图2为本申请所提供组合摄像机的主视结构示意图，图3为图2所示组合摄像机的右侧视图结构示意图，图4为图2的A-A向剖视结构示意图，图5为图3的B-B向剖视结构示意图。
结合图2至5所示，本具体实施例所提供的组合摄像机包括内置有第一摄像头11的第一摄像机外壳10，第一摄像机外壳10的一面设有可相对第一摄像机外壳10转动的转动盘30，转动盘30上固定有转动支架，转动支架上设置有可相对转动支架转动的第二摄像机外壳20，第二摄像机外壳20内设有第二摄像头21。
需要说明的是，本实施例中转动盘30和第二摄像机外壳20两者的转动轴线相互异面垂直，本文在此以水平和垂直加以区分，也就是说，转动轴30相对于第一摄像机外壳10在水平面内转动，第二摄像机外壳20相对于转动支架在竖直平面内转动。
当然，在满足组合摄像机监控需求功能基础上，转动盘30和第二摄像机外壳20两者的转动轴线亦可成相交，具体角度参数本领域技术人员根据实际结构设定。
详细地，第一摄像机外壳10具有内凹的转动盘插装孔10a，转动盘30完全插装于转动盘插装孔10a内并通过轴承与第一摄像机外壳10直接转动连接，第一驱动机构驱动转动盘30相对于第一摄像机外壳10在水平面内转动。
优选地，本具体实施例中第一驱动机构包括第一电机12和第一同步带传动机构，其中；第一电机12固定安装于第一摄像机外壳10内，第一同步带传动机构包括第一主动同步轮13、第一从动同步轮14和第一同步带15，第一从动同步轮14与转动盘30同轴且固定连接，第一主动同步轮13与第一电机12的电枢轴同轴且固定连接，第一同步带15与第一主动同步轮13和第一从动同步轮14张紧内齿啮合。
即，第一电机12通过第一同步带传动机构驱动转动盘30相对于第一摄像机外壳10在水平面内转动，由于转动盘30与转动支架固定连接，且第二 摄像机外壳20与转动支架直接转动连接，而第二摄像头21又固设于第二摄像机外壳20，因此，转动盘30相对于第一摄像机外壳10在水平面内转动可带动第二摄像头21同时转动，以便调整第二摄像头21在水平面内的监控角度。
继续结合图4和5所示，转动支架包括两个转动支架，这两个转动支架分设于第二摄像头21两侧，为了便于本领域技术人员更好地理解这种摄像机的具体结构，本文在此通过方位词左右来区分这两个转动支架，方位词左右是以图4中第二摄像机外壳21为基准来设定，即两个转动支架中位于第二摄像机外壳21左手侧的为左转动支架40，位于第二摄像机外壳21右手侧的为右转动支架41。第二摄像机外壳20通过轴承与左转动支架40和右转动支架41转动连接。
详细地，左转动支架40具有支架轴承孔，右转动支架具有支架转轴，第二摄像机外壳20具有第二摄像机外壳轴承孔和第二摄像机外壳转轴，且，支架轴承孔、支架转轴、第二摄像机外壳轴承孔和第二摄像机外壳转轴四者同心设置，左转动架40和第二摄像机外壳20通过安装于支架轴承孔和第二摄像机外壳转轴之间的轴承转动连接，右转动支架41和第二摄像机外壳20通过安装于第二摄像机外壳轴承孔和支架转轴之间的轴承转动连接。第二摄像机外壳20在第二驱动机构驱动下相对于左转动支架40和右转动支架41在水平面内转动。
同样，本具体实施例中第二驱动机构包括第二电机22和第二同步带传动机构，其中；第二电机22固定安装于第二摄像机外壳20内，第二同步带传动机构包括第二主动同步轮(图中未示出)、第二从动同步轮24和第二同步带25，第二从动同步轮24与支架转轴同轴且固定连接，第二主动同步轮与第二电机22的电枢轴同轴且固定连接，第二同步带25与第二主动同步轮和第二从动同步轮24张紧内齿啮合。
也即，第二电机22通过第二同步带传动机构驱动第二摄像机外壳20在竖直面内转动，由于第二摄像头21又固设于第二摄像机外壳20，因此，转动盘30相对于第一摄像机外壳10在竖直面内转动可带动第二摄像头21转动，以便调整第二摄像头21在竖直面内的监控角度。
显然，这种组合摄像机中第二摄像机外壳20通过转动盘30和转动支架两者与第一摄像机外壳10直接转动连接，省去了现有枪联机结构的组合摄像机中安装支架和底座，从而简化了整体结构且缩小了其竖直方向的高度尺寸。
此外，与现有技术相比，第一电机12和第二电机22两者分设于第一摄像机外壳10和第二摄像机外壳20，从而在一定程度上整体结构得到简化且缩小了竖直尺寸。且，采用同步带传动机构作为第一传动机构和第二传动机构，使得组合摄像机整体结构紧凑、传动平稳。当然，在满足减速功能及装配工艺要求的基础上，第二传动机构和第一传动机构亦可为齿轮传动机构、链轮传动机构等。
进一步地，继续参见图4和5所示，该组合摄像机的主板60集成了电源模块、机芯转接模块和云台模块；其中，电源模块用于为第一摄像头11、第二摄像头21、第一电机12和第二电机22供电，云台模块用于控制第一电机12和第二电机22，机芯转接模块用于在第一摄像头11、第二摄像头21和控制台三者之间进行信号转接(具体包括网络、BNC、485、uart等)。
此外，该组合摄像机还包括连接线50，连接线50一端与主板60电连接，另一端穿过第一摄像机外壳10、转动盘30并穿入第二摄像机外壳20内部与第二摄像头21和第二电机22电连接。
可以想见，与现有技术中第一摄像机和第二摄像机拼装而成的组合摄像机相比，本实施例中组合摄像机采用集成多个功能模块主板60，且该主板60同时为第一摄像头11和第二摄像头21供电、控制，极大地简化了其结构。
优选地，继续参见图4和5所示，第一摄像机外壳10为筒状外壳，第一摄像头11、转动盘30和第一电机12沿第一摄像机外壳10的长度方向顺次排布，主板60沿第一摄像机外壳10的长度方向设置。
如此设置，使得组合摄像机结构紧凑合理，可进一步地限定组合摄像机在竖直方向上的高度尺寸。
另外，本实施例中第一摄像头11的数量为三个，三个第一摄像头11沿弧形顺次分布，以便获取监控区域的第一图像。可以理解，第一摄像头11的数量限定为三个仅为示例性说明，本领域技术人员可根据实际监控需求确定合适数量的第一摄像头11，也即，对第一摄像头11具体数量的任意设定均落 入本申请的保护范围。
更进一步地，结合图4和5可知，第一摄像机外壳10和第二摄像机外壳20均为防水密封壳体，从而使得第一摄像头11、第二摄像头21和主板60等功能元件均密封安装，以便组合摄像机具备一定的防水功能，继而扩大其适用范围。
详细地，第一摄像机外壳10具有第一防水密封腔1a、第一图像采集孔和第一透明罩103；第一摄像头11、主板60和第一电机12均位于第一防水密封腔1a内，第一图像采集孔与第一防水密封腔1a连通并由第一透明罩103封堵，以便第一摄像头11通过所述第一透明罩103采集外部图像。
更为详细地，第一摄像机外壳10包括第一底壳101和第一壳盖102；其中，第一底壳101和第一壳盖102密封连接为第一防水密封腔1a，第一摄像头11固设于第一防水密封腔1a内，第一图像采集孔开设于第一底壳101或者第一壳盖102。
同样，第二摄像机外壳20具有第二防水密封腔2a、第二图像采集孔和第二透明罩203；其中，第二摄像头21和第二电机22均位于第二防水密封腔2a内，第二图像采集孔与第二防水密封腔2a连通并由第二透明罩203封堵，以便第二摄像头21通过第二透明罩203采集外部图像。
更为具体地，第二摄像机外壳20包括第二底壳201和第二壳盖202；其中，第二底壳201和第二壳盖202密封连接为第二防水密封腔2a，第二图像采集孔开设于第二底壳201或第二壳盖202。
继续参见图2和3所示，本实施例中第一摄像机外壳10为枪形，第二摄像机外壳20为球形。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
