图1所示为本公开一示例性实施例的摄像机100的立体示意图；图2所示为图1所示的摄像机100另一角度的立体示意图。
参见图1所示，本公开提供一种摄像机100，包括支架10、镜头组件11和反射镜12。支架10作为支撑结构，用于固定镜头组件11、反射镜12等部件，摄像机100可以通过支架10安装于外部结构上。支架10包括水平延伸的基部79和沿第一方向18设置于基部79两侧的第一支架80和第二支架81，第一方向18平行于基部79，第一支架80用于固定反射镜12，第二支架81用于固定镜头组件11，反射镜12和镜头组件11沿第一方向18排布于支架10，且可转动的设置于支架10。支架10具有第二方向19，第二方向19限定为垂直于基部79且与第一方向18垂直。镜头组件11包括用于进行拍摄和监控的镜头13，镜头13可以是长焦镜头、标准镜头等种类，长焦镜头是指比标准镜头的焦距长的摄影镜头，通常用于远距离的景物拍摄及监控，拍摄的景物空间范围较 小，监控的角度范围较小。在一些实施例中，镜头13包括起到固定作用的镜筒(未示出)、设置于镜筒外表面起到防止镜头13损伤作用的保护壳78、相对设置的镜头13的前端14和镜头13的尾端15、以及设置于镜头13的前端14的镜片16。
反射镜12包括反射面17，反射镜12可以是椭圆形、矩形等形状，也可以是凹面镜、凸面镜、平面镜等种类，可以根据设置于镜头13的前端14的镜片16至反射面17的距离、镜头组件11及反射镜12设定的旋转角度等要求进行选择，本公开不做限制。在本实施例中，反射镜12为成像为16：9的矩形平面镜，如此设置可以和镜头13的实际视场角匹配，也可以使结构设计更加紧凑。
在一些实施例中，反射镜12以平行于第二方向19的第一轴线为轴可转动地设置于支架10，镜头组件11可转动地设置于支架10。在一些实施例中，镜头组件11可以以第二方向19为轴可转动地设置于支架10。在另一些实施例中，镜头组件11可以以垂直于第一方向18和第二方向19的第三方向20为轴可转动地设置于支架10。在本实施例中，第一支架80保持反射镜12，或可理解为反射镜12设置于第一支架80；第二支架81保持镜头组件11，或可理解为镜头组件11设置于第二支架81，以使得反射镜12可相对支架10以第一轴线转动且镜头组件11可相对支架10俯仰运动，即反射镜12以平行于第二方向19的第一轴线(未示出)为轴可转动地设置于第一支架80，镜头组件11相对于基部79做俯仰转动，第二支架81以第二方向19为轴可转动地设置于基部79，以使得镜头组件11可以以第二方向19为轴相对于基部79做水平转动。
即至少包括以下几种情况：反射镜12不转动，镜头组件11相对于支架10做俯仰运动或水平旋转；反射镜12相对于支架10做水平旋转，镜头组件11不转动；反射镜12相对于支架10做水平旋转，镜头组件11相对于支架10做俯仰运动或水平旋转；反射镜12相对于支架10做垂直旋转，镜头组件11相对于支架10做俯仰运动或水平旋转。反射镜12的旋转角度和镜头组件11的旋转角度可以根据实际的需要制定。镜片16朝向反射镜12，镜头13用于接收反射镜12反射的光线，且反射镜12可相对于镜片16倾斜或转动，反射镜12用于将至少部分入射光线反射至镜片16，即可理解为通过调整反射镜12与镜片16间的相对角度，使得由反射镜12反射后的光线中至少部分射入至镜片16，以便于通过反射成像来实现镜头13的大范围监控。摄像机100的视场区域由反射镜12的反射区域确定，即可以通过调整镜头组件11和反射镜12的旋转角度来调整摄像机100的视场区域，通过对摄像机100视场区域的调整来实现摄像机100的大范围监控。
采用反射镜12以第二方向19为轴可转动地设置于支架10，镜头组件11可转动地设置于支架10的方案，可以扩大监控范围，实现摄像机100的大范围监控。在一些情况下，镜头13为长焦镜头时，可以实现摄像机100远距离大范围监控的目的。
图3所示为图1所示的摄像机100在反射镜12静止、镜头组件11处于两个极限位置时的立体示意图；图4所示为图1所示的摄像机100在镜头组件11静止、反射镜12处于两个极限位置时的立体示意图。
参见图1和图3所示，镜头13包括光轴，本文中陈述的光轴可以认为是镜头13的中轴线，摄像机100的视场区域由反射镜12的反射区域确定；在镜头组件11俯仰运动至第一角度时，镜头13的光轴与反射镜12相交于第一位置；在镜头组件11俯仰运动至第二角度时，镜头13的光轴与反射镜12相交于第二位置；其中，视场区域的中心点位于连接第一位置与第二位置的线段上，第一位置与第二位置均不是反射镜12的中心，且该线段偏离反射镜12的中心，或可理解为，由第一位置与第二位置确定镜头组件11的运动轨迹，该运动轨迹可以被视为在镜头组件11俯仰转动时，光轴与反射镜12交点的连线集合，第一位置与第二位置均不是反射镜12的中心，且该运动轨迹偏离反射镜12的中心。镜头组件11处于两个极限位置时，镜头组件11俯仰转动的角度分别为最大仰角和最大俯角，第一角度可以是最大仰角、最大俯角或最大仰角和最大俯角范围内的任意一个角度，第二角度同理。
在一些实施例中，连接第一位置与第二位置的线段与第一轴线平行(或可理解为沿纵向延伸)，该线段将反射镜12的反射面17划分为第一区域和第二区域，第一区域的面积大于第二区域的面积(即该线段在反射面17的平面内沿垂直于第一轴线的方向上偏离第一轴线)，且第一区域限定为由第一区域反射后的光线全部地射入镜片16，以使得经由反射镜12反射后的光线中超过一半的光线能够射入镜片16。此时，在反射镜12不转动，镜头组件11相对于基部79做稳定的俯仰转动的情况下，可以使反射镜12中用于反射光线至镜头组件11的部分面积超过反射面17的一半面积，使得反射光线更易通过反射面17进入到镜头13中，在保证实现设定摄像机100的视场区域范围的同时，使得整体的结构更加紧凑。
参见图1和图4所示，反射镜12处于两个极限位置时，反射镜12以第一轴线为轴相对于基部79水平转动的角度为最大顺时针旋转角度和最大逆时针旋转角度，当反射镜12转动至最大顺时针角度和最大逆时针角度时，光轴与反射镜12相交的点均位于反射面17内，镜头13的拍摄范围完全落在反射面17内，使得全部入射光线都可以通过反射镜12进入到镜头13内，防止出现拍摄画面不全的现象。
参见图3和图4所示，本公开以镜头组件11相对于支架10做俯仰运动，运动角度范围为+10°至－10°；反射镜12相对于支架10做水平旋转，旋转角度范围为+15°至－15°为例，对反射镜12及镜头组件11的运动情况进行说明。
参见图3所示，当反射镜12相对于支架10静止，镜头组件11相对于支架10的运动角度范围为+10°至－10°时，监控位置上下变化，可以扩大垂直方向的监控范围。参见图4所示，当镜头组件11相对于支架10静止，反射镜12相对于支架10做旋转角度范围为+15°至-15°的旋转时，监控位置左右变化，可以实现水平方向监控范围的扩展，可以通过计算得出反射镜12旋转的角度为15+15＝30°，监控范围扩大30×2＝60°。当镜头13为长焦镜头时，长焦镜头本身水平角度为15°至30°，则摄像机100的监控范围为75°至90°，可以满足大部分情况下的监控需求，相当于广角监控，即能够实现摄像机100的远距离大范围监控。
图5所示为图1所示的摄像机100的支架10的立体示意图。
参见图1和图5所示，在一些实施例中，第一支架80的高度大于基部79的高度，即第一支架80沿第二方向19(或可理解为沿着纵向轴线)凸出于基部79设置，如此设置使得反射镜12可以配合镜头组件11的设置高度而确定相应的设置位置。在一些实施例中，第一支架80的高度小于第二支架81的高度，其中，第一支架80用于支撑反射镜12以使反射镜12可沿着纵向轴线相对第一支架80转动，第二支架81用于支撑镜头组件11以使得镜头组件11能够相对第二支架81俯仰运动；其中，反射镜12的反射面17与所述镜头组件11的入光面构成锐角。第一支架80包括平面部82和连接于平面部82和基部79之间的连接壁83，连接壁83可以垂直于所述基部79设置，也可以相对于基部79倾斜设置，本公开不做限制，平面部82与基部79之间的距离取决于镜头组件11俯仰转动的角度范围及镜头组件11相对于基部79水平设置时光轴与基部79的距离，以使反射镜12可以将至少部分入射光线反射至镜头13，实现通过调整镜头组件11和反射镜12的旋转角度来调整摄像机100的视场区域的效果。在本实施例中，平面部82与基部79之间的距离由镜头组件11俯仰运动的预设角度范围及反射镜12的预设尺寸确定，以使得在镜头组件11处于预设角度范围中最小俯仰角度和最大俯仰角度时，镜头13的光轴均能够与反射镜12相交，或可理解为，平面部82与基部79之间的距离被限定为：当镜头组件11俯仰转动至最大俯角和最大仰角时，光轴与反射镜12相交的点位于反射面17内，镜头13的拍摄范围完全落在反射面17内，使得在镜头13视场角范围内的全部入射光线都可以通过反射镜12进入到镜头13内，防止出现显示画面不全的情况产生。
图6所示为图1所示的摄像机100的镜头组件11的立体分解图；图7所示为图1所示的摄像机100的镜头组件11的立体示意图。
参见图1、图5至图7所示，在一些实施例中，支架10设有与凸起38配合的弧形槽39(参见图1和图5所示)，第二支架81包括沿第二方向19延伸设置的壁面86，壁面86设有沿第二方向 延伸的弧形槽39，镜头组件11设置有与弧形槽39配合的凸起38，弧形槽39的圆心朝向反射镜12，也就是靠近反射镜12一侧设置，使得弧形槽39朝着远离第一支架80的方向弯曲，凸起38可沿弧形槽39滑动地设置于弧形槽39，凸起38和弧形槽39之间的摩擦力在一定程度上为镜头组件11提供了支撑力，使得镜头组件11可以在第三方向20上保持平衡，保证镜头组件11在旋转过程中的稳定性。在本实施例中，支架10沿弧形槽39的边沿间隔设置有刻度线40(参见图1所示)，设置刻度线40可以肉眼观测到镜头组件11当前的位置，保证镜头组件11运行的精确性。
在一些实施例中，弧形槽39包括第一端84和第二端85，第一端84限定镜头组件11的最大仰角，第二端85限定镜头组件11的最大俯角，以限制镜头组件11的俯仰转动角度。弧形槽39的弧度限定为：镜头组件11沿着第一端84运动至第二端85，镜头13的光轴始终与反射镜12相交。或可理解为，镜头组件11沿弧形槽39做俯仰转动，镜头组件11和反射镜12限定为：镜头组件11自第一端84运动至第二端85的过程中，光轴与反射镜12相交的点均位于反射面17内，通过限定第二支架81上弧形槽39第一端84和第二端85的设置位置，来限定镜头组件11的最大仰角和最大俯角，以使镜头13视场角范围内的全部入射光线都可以通过反射镜12进入到镜头13内。
在一些实施例中，镜头组件11自第一端84运动至第二端85的过程中，光轴与反射镜12相交的点所构成的线段将反射面17划分为两个部分，即镜头组件11的运动轨迹将反射面17划分为两个部分，其中用于反射光线至镜头组件11的部分的面积大于反射面17面积的一半，可以使得反射光线更易通过反射面17进入到镜头13中。
在一些实施例中，第二支架81包括沿垂直于第一方向18和第二方向19的第三方向20相对设置的第一部分87和第二部分88，第一部分87和第二部分88可以正对设置，也可以在第一方向18上交错设置，第一部分87包括壁面86，弧形槽39设置于第一部分87，镜头组件11沿第三方向20设置于第一部分87和第二部分88之间，以便以第三方向20为轴相对于基部79做俯仰转动，使得镜头组件11在第三方向20上的平衡性更好，可以保证镜头组件11在转动过程中的稳定性。

在一些实施例中，还包括固定设置于支架10的夹持块27(参见图1所示)，固定方式可以是螺栓固定，夹持块27沿第三方向20至少部分覆盖于转轴轴承26，第一侧面22和夹持块27可以沿第三方向20贴紧设置于转轴轴承26的两侧，可以防止转轴轴承26在安装孔25内的位置发生变化，保证转轴轴承26安装的可靠性。
