本申请实施例公开的球形摄像机中，球体安装在球罩内，能沿垂直于底座的支撑面转动，球罩通过转动组件设置在底座上，使得球罩带动球体在平行于底座的支撑面的方向转动。球体在垂直于支撑面的方向上转动时，能够与弹性阻尼件贴合，进而实现限制球体在设定角度范围内转动的目的。弹性阻尼件具有较好的弹性阻尼效果，能减小对球体的摩擦损坏。可见，本申请实施例公开的球形摄像机能解决目前的球形摄像机的球体在转动过程中会与球罩直接接触制动而较容易损坏的问题。
本申请实施例采用的上述至少一个技术方案能够达到以下有益效果：
本申请实施例公开的球形摄像机中，球罩通过转动组件连接在底座上，球罩能在平行于底座的支撑面的方向(即P向)转动，球体铰接在球罩内，且能在垂直于支撑面的方向(即T向)转动。螺纹锁紧件能够与球体锁紧架的悬臂结构上的螺纹孔螺纹配合，旋进螺纹锁紧件，会使得螺纹锁紧件拉拽悬臂结构，进而使得悬臂结构产生朝向球体方向的形变，悬臂结构的上述形变会压紧弹性阻尼件，进而使得弹性阻尼件与球体贴合而阻止球体在垂直于底座的支撑面的方向转动。螺纹锁紧件的旋进会使得旋进端顶向弹性伸缩件，弹性伸缩件受压会驱动制动块与环状凹陷定位配合，最终阻止球罩带动球体相对于底座转动，也就实现了球体在平行于底座的支撑方向的转动锁紧。当螺纹锁紧件旋出的过程，螺纹锁紧件对悬臂结构及弹性伸缩件的作用消除，进而实现锁紧的解除。
通过上述工作过程可以看出，用户只需要操作螺纹锁紧件即可实现对P向和T向的锁紧或解除锁紧，相比于背景技术所述的通过两个锁紧螺钉分别实现P向及T向的锁紧或解除锁紧而言，能够较方便地实现锁紧操控，达到提高锁紧效率的目的。可见，本申请实施例公开的球形摄像机能解决目前的球形摄像机需要操控两个锁紧螺钉来分别实现P向和T向的锁紧操作存在的操作不方便的问题。

具体实施方式
为使本申请的目的、技术方案、及优点更加清楚明白，以下参照附图并举实施例，对本申请进一步详细说明。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
以下结合附图，详细说明本申请各实施例提供的技术方案。
本申请实施例公开一种球形摄像机，如图1和2所示，该球形摄像机包括底座100、转动组件200、球体锁紧架300、球体400和球罩500。
球罩500通过转动组件200连接在底座100，使得球罩500能相对于底座100转动。球罩500能在平行于底座100的支撑面的方向相对于底座100转动，如图3所示。球体400铰接于球罩500内，且能在垂直于底座100的支撑面的方向转动，如图4所示。球体锁紧架300设置在转动组件200上，且与球体400之间设置有弹性阻尼件600。弹性阻尼件600在球体400在垂直于底座100的支撑面转动时与球体400贴合，从而实现对球体400转动角度范围的限制。
本申请实施例公开的球形摄像机中，球体400安装在球罩500内，能沿垂直于底座100的支撑面转动，球罩500通过转动组件200设置在底座100上，使得球罩500带动球体400在平行于底座100的支撑面上的方向转动。球体400在垂直于支撑面的方向上转动时，能够与弹性阻尼件600贴合，进而实现限制球体400在设定角度范围内转动的目的。弹性阻尼件600具有较好的弹性阻尼效果，能减小对球体400的摩擦损坏。可见，本申请实施例公开的球形摄像机能解决目前的球形摄像机的球体在转动过程中会与球罩直接接触制动而较容易损坏的问题。
请参考图5-7，本申请实施例中，球形摄像机还包括铰接轴410，球罩500的内壁可以设置有凹陷510，铰接轴410的一端连接在球体400上，另一端安装在凹陷510内，进而实现球体400在垂直于底座100的支撑面的方向转动。
具体的，铰接轴410包括固定轴和转轴，固定轴的一端卡接在凹陷510内，转轴的一端与固定轴的另一端转动相连，转轴的另一端与球体400固定 相连。比如，固定轴与转轴套接配合，固定轴与转轴之间形成转动副，这样，实现了转轴的一端与固定轴的另一端转动相连。为了提高装配的紧凑度，减小球形摄像机的体积，具体的，固定轴的一部分和转轴可以内置于球体400内。
请再次参考图1，底座100是球形摄像机的基座，为其他部件提供安装基础。一种具体的实施方式中，底座100可以包括筒状体110和安装盘120。安装盘120设置在筒状体110背离球体400的一侧，筒状体110的内腔为容线腔。球形摄像机的线缆可以布置在容线腔中，起到藏线的功能。转动组件200安装在筒状体110朝向球体400的一侧，转动组件200设置有连通容线腔的避让孔210，以不影响球形摄像机的球体400的线缆穿线。
转动组件200是实现球体400在平行于底座100的支撑面转动的部件，实现转动组件200功能的机构有多种，一种具体的实施方式为：转动组件200可以包括转盘钣金220和旋转转盘230，转盘钣金220固定在筒状体110上，旋转转盘230与筒状体110构成转动副，旋转转盘230与球体锁紧架300固定相连。转盘钣金220能够提高连接强度，当然，还可以采用其他的中间连接件作为旋转转盘230的连接件。
在装配完成之后，容线腔中的线缆会通过筒状体110以及转动组件200的避让孔210脱落至球体400与球罩500之间，进而会影响球体400的转动。基于此，本申请实施例公开的球形摄像机还可以包括底座盖130，底座盖130固定在筒状体110朝向球体400的一侧以封闭容线腔，底座盖130设置有连通避让孔210和容线腔的穿线孔131。底座盖130在不影响线缆穿线的前提下，能避免线缆从容线腔向球罩500与球体400之间的间隙中脱落。
本申请实施例中，弹性阻尼件600由弹性材质制成，弹性阻尼件可以是阻尼硅胶件。
球罩500用于安装球体400，当然为了不影响球体400上的摄像头的摄像，球罩500上可以设置有避让豁口，由于球体400能相对于球罩500转动，两者之间存在间隙。为了提高球形摄像机的装配紧凑性，同时避免异物进入间隙而影响球体400转动，可选的，本申请实施例公开的球形摄像机还可以包括球罩装饰片700，球罩装饰片700封堵在避让豁口的边缘与球体400之间的 缝隙中，进而起到封堵的作用。
如上所述，球体可以在平行于底座的支撑面方向(也称为P向)和垂直于底座的支撑面的方向(也称为T向)转动，进而达到调节摄像头摄像角度的目的。现有方案中，球形摄像机的P向和T向锁紧均设置有锁紧螺钉，进而分别实现锁紧。在锁紧的过程中，用户需要操控两个锁紧螺钉来分别实现球体在P向和T向的锁紧。操控两个锁紧螺钉存在操作不方便的问题，影响锁紧效率。
下述实施例提供一种球形摄像机，以解决目前的球形摄像机需要操控两个锁紧螺钉存在操作不方便的问题。
请参考图7-9，球体锁紧架300的一端固定在转动组件200上，另一端为悬臂结构310。悬臂结构310与球体400之间设置有弹性阻尼件600。
球罩500上设置有螺纹锁紧件800，悬臂结构310上设置有与螺纹锁紧件800螺纹配合的螺纹孔，底座100上设置有环状凹陷，该环状凹陷通常与底座100的支撑面平行。
转动组件200设置有通孔，通孔内设置有弹性伸缩件900，弹性伸缩件900可以是螺旋弹簧、弹性橡胶块等弹性伸缩性能较好的部件。弹性伸缩件900的一端与螺纹锁紧件800的旋进端相连，另一端连接有能与环状凹陷定位配合的制动块910，制动块910能与环状凹陷在球罩500平行于底座100的支撑面的转动方向定位配合，达到阻止转动的目的。弹性伸缩件900能随旋进端的运动驱动制动块910与环状凹陷定位配合或分离。
螺纹锁紧件800与螺纹孔配合，以通过悬臂结构310的变形控制弹性阻尼件600与球体400的制动贴合或分离。
本申请实施例公开的球形摄像机中，球罩500通过转动组件200连接在底座100上，球罩500能在平行于底座100的支撑面的方向(即P向)转动，球体400铰接在球罩500内，且能在垂直于支撑面的方向(即T向)转动。螺纹锁紧件800能够与球体锁紧架300的悬臂结构310上的螺纹孔螺纹配合，旋进螺纹锁紧件800，会使得螺纹锁紧件800拉拽悬臂结构310，进而使得悬臂结构310产生朝向球体400方向的形变，悬臂结构310的上述形变会压紧 弹性阻尼件600，进而使得弹性阻尼件60与球体400贴合而阻止球体400在垂直于底座100的支撑面的方向转动。螺纹锁紧件800的旋进会使得旋进端顶向弹性伸缩件900，弹性伸缩件900受压会驱动制动块910与环状凹陷定位配合，最终阻止球罩500带动球体400相对于底座100转动，也就实现了球体400在平行于底座100的支撑方向的转动锁紧。当螺纹锁紧件800旋出的过程，螺纹锁紧件800对悬臂结构310及弹性伸缩件900的作用消除，进而实现锁紧的解除。
通过上述工作过程可以看出，用户只需要操作螺纹锁紧件800即可实现对P向和T向的锁紧或解除锁紧，相比于背景技术所述的通过两个锁紧螺钉分别实现P向及T向的锁紧或解除锁紧而言，能够较方便地实现锁紧操控，达到提高锁紧效率的目的。可见，本申请实施例公开的球形摄像机能解决目前的球形摄像机需要操控两个锁紧螺钉来分别实现P向和T向的锁紧操作存在的操作不方便的问题。
与此同时，通过一个螺纹锁紧件800即可实现两个方向的锁紧，能减少螺纹锁紧件800的布置数量，有利于提高球形摄像机的美观度。而且，在锁紧的过程中，弹性阻尼件600和弹性伸缩件900均为柔性机构，使得锁紧配合为柔性接触，这可以较大幅度地降低相关零件的公差精度，提高零部件的可制造性，还能够为后续的锁紧力调节预留较大的设计改动空间。
螺纹锁紧件800的旋进端的旋进会压缩弹性伸缩件900，进而通过弹性伸缩件900实现对制动块910的驱动。为了提高驱动效果，本申请实施例公开的球形摄像机还可以包括中间运动块920，中间运动块920滑动地设置在通孔内，且相抵于螺纹锁紧件800的旋进端和弹性伸缩件900之间。螺纹锁紧件800的旋进端会驱动中间运动块920在通孔内滑动，进而通过中间运动块920驱动弹性伸缩件900推动制动块910，由于中间运动块920在通孔内滑动，因此，旋进端通过中间运动块920能提高对弹性伸缩件900的驱动稳定性。
为了提高定位效果，制动块910的一端可以为制动尖端，另一端与弹性伸缩件900相连，制动尖端与环状凹陷定位配合。在弹性伸缩件900的推动下，制动尖端可以伸入到环状凹陷中。制动尖端能够提高定位配合的准确性，同时可以降低定位对零件制造精度的要求。
如上文所述，螺纹锁紧件800旋出的过程中，螺纹锁紧件800对悬臂结构310的作用力会消除，悬臂结构310会弹性复位，进而解除对弹性阻尼件600的压力，而使得弹性阻尼件600与球体400分离。随着螺纹锁紧件800的旋出，螺纹锁紧件800的旋进端的旋出会使得弹性伸缩件900对制动块910的驱动作用解除。具体的，由于弹性伸缩件900的复位，制动块910可以依靠自身的重力从环状凹陷内脱离，也可以通过旋进端带动弹性伸缩件900，进而通过弹性伸缩件900带动制动块910脱离环状凹陷。上述两种情况均是螺纹锁紧件800的旋进端运动导致的结果，可以认为是由旋进端的运动实现的驱动结果。
请参考图5-7，本申请实施例中，球罩500的内壁可以设置有凹陷510，球体400的铰接轴410的一端连接在球体400上，另一端安装在凹陷510内，进而实现球体400在垂直于底座100的支撑面的方向的转动。
具体的，铰接轴410可以包括固定轴和转轴，固定轴的一端卡接在凹陷510内，转轴的一端与固定轴的另一端转动相连，转轴的另一端与球体400固定相连。具体的，固定轴与转轴可以套接配合，进而使得两者之间形成转动副。为了提高装配的紧凑度，减小球形摄像机的体积，可选的方案中，固定轴的一部分和转轴可以内置于球体400内。
请再次参考图1，底座100是球形摄像机的基座，为其他部件提供安装基础。一种具体的实施方式中，底座100可以包括筒状体110和安装盘120。安装盘120用于实现整个球形摄像机的安装，通常，安装盘120上设置有安装空位。安装盘120设置在筒状体110背离球体400的一侧，筒状体110的内腔为容线腔。球形摄像机的线缆可以布置在容线腔中，起到藏线的功能。转动组件200安装在筒状体110朝向球体400的一侧，转动组件200设置有连通容线腔的避让孔210，以不影响球形摄像机的球体400的线缆穿线。
转动组件200是实现球体400在平行于底座100的支撑面转动的部件，实现转动组件200功能的机构有多种，一种具体的实施方式为：转动组件200可以包括转盘钣金220和旋转转盘230，转盘钣金220固定在筒状体110上，旋转转盘230与筒状体110构成转动副，旋转转盘230与球体锁紧架300固定相连。转盘钣金220能够提高连接强度，当然，还可以采用其他的中间连 接件作为转动组件200的连接件。
在装配完成之后，容线腔中的线缆会通过筒状体110以及转动组件200的避让孔210脱落至球体400与球罩500之间，进而影响球体400的转动。基于此，本申请实施例公开的球形摄像机还可以包括底座盖130，底座盖130固定在筒状体110朝向球体400的一侧以封闭容线腔，底座盖130设置有连通避让孔210和容线腔的穿线孔131。底座盖130不影响线缆穿线的前提下，能避免线缆从容线腔向球罩500与球体400之间的间隙中脱落。
本申请实施例中，弹性阻尼件600由弹性材质制成，弹性阻尼件可以是阻尼硅胶件。
球罩500用于安装球体400，当然为了不影响球体400上的摄像头的摄像，球罩500上设置有避让豁口，由于球体400能相对于球罩500转动，两者之间存在间隙。为了提高球形摄像机的装配紧凑性，同时避免异物进入间隙而影响球体400转动，可选的，本申请实施例公开的球形摄像机还可以包括球罩装饰片700，如图1所示，球罩装饰片700封堵在避让豁口的边缘与球体400之间的缝隙中。
本申请实施例提供的球形摄像机中，可以通过调节弹性阻尼件600和弹性伸缩件900的刚性和过盈量，来达到调节锁紧力大小的目的，进而可以实现不同锁紧力大小的调节。
随着社会的发展，摄像机的应用越来越广泛。摄像机通常包括补光灯和镜头，补光灯用于为镜头的拍摄实施补光。
为了实现更好的防护，摄像机通常还包括透明罩，透明罩罩设在补光灯和镜头上。以半球摄像机为例，半球状透明罩罩设在半球摄像机的补光灯和镜头上。在工作的过程中，补光灯产生的光线会经过透明罩的反射而进入到镜头中，进而会引起镜头所获取图像的异常。为了解决此问题，摄像机的透明罩内部设置有圆环状的阻光隔离件，圆环状的阻光隔离件绕设在镜头的周围，且与透明罩的内壁贴合，最终能达到阻止补光灯的光线进入镜头内的目的。
随着拍摄需求的扩大，目前的镜头的视场角度越来越大，镜头的对角线 视场会加大，最终导致圆环状的阻光隔离件的尺寸加大。圆环状的阻光隔离件的尺寸加大会遮挡补光灯的光线，导致补光无法满足摄像的要求。
请参考图10-3，本申请实施例公开一种摄像机，该摄像机包括阻光隔离件1、补光灯2、透明罩7、前端罩8和镜头9。
其中，阻光隔离件1、前端罩8、镜头9、补光灯2均位于透明罩7内，透明罩7起到防护、透光的作用。镜头9安装在前端罩8内，前端罩8设置有避让镜头9的避让孔，前端罩8通常罩设在凸出于摄像机的前壳4和底座5所形成的组件容纳腔之外的组件上，起到防护、提高装配紧凑度的作用。摄像机的一些基础组件，例如主板6，则设置在摄像机的组件容纳腔之中。
补光灯2设置在镜头9的外侧，用于为镜头9的拍摄实施补光。阻光隔离件1围绕在镜头9的外侧，阻光隔离件1夹设在前端罩8和透明罩7之间，以实现隔离补光灯2和镜头9。阻光隔离件1的横截面的为长方形，需要说明的是，阻光隔离件1围绕在镜头9的***，阻光隔离件1的横截面为平行于阻光隔离件1的围绕方向而截成的平面，该平面形状为长方形。
本申请实施例提供的摄像机中，将圆环状的阻光隔离件更改为横截面为正方形的阻光隔离件1，在视场角度增大的情况下，在同等安装空间内，横截面为正方形的阻光隔离件1满足视场角度的前提下，会占据更小的面积，进而不会对补光灯2的光线产生遮挡，也就不会影响摄像机的正常摄像工作。可见，本申请实施例公开的摄像机能解决目前的摄像机在镜头视场角增大的前提下阻光隔离件会影响补光的问题。
下面以镜头9为超广角镜头为例，超广角镜头的对角线视场角可以达到200°，水平视场角可以达到150°。若采用圆环状的阻光隔离件，圆环状的阻光隔离件尺寸势必会随着对角线视场角的增大而增大，尺寸加大后的圆环状的阻光隔离件会遮挡补光灯的光线。阻光隔离件贴合在透明罩上，且较为靠近补光灯的边缘可以称之为目标边缘，通过仿真技术验证，补光灯2的光线投射方向与补光灯2的光源中心与目标边缘的连线之间的夹角不小于30°，才能确保补光灯2补光良好，为了描述方便，本文称上述夹角为避光角。而尺寸加大后的圆环状的阻光隔离件与补光灯2之间的避光角只能达到25°，补光灯的光线被遮挡较为严重，无法满足补光要求。
而采用本申请实施例所公开的横截面为长方形的阻光隔离件1，在相同的安装空间内，能够减小阻光隔离件1的尺寸，长方形横截面的对角线能满足超广角镜头的对角视场角为200°的要求，长方形横截面的长度方向能满足超广角镜头的水平视角为150°的要求，该横截面为长方形的阻光隔离件1相当于在相同的安装空间内的圆环状阻光隔离件的内切长方形，能够减小对补光灯的光线遮挡。请参考图12，图12为图11中左侧补光灯及补光灯周围结构的放大示意图，经过验证，在镜头9为超广角镜头的前提下，本申请实施例公开的摄像机的遮光角可以达到38°，已经超过30°，进而能达到较好的补光效果。
前端罩8的外侧可以设置有前端板，补光灯2可以安装在前端板上。前端板可以为穿过前端罩8的侧壁，且与前端罩8内的电源组件电连接的PCB板，进而可以达到直接从摄像机的内部引入电源的目的。
本申请实施例公开的摄像机还可以包括灯罩3，灯罩3罩设在补光灯2上。通常，补光灯2为多个，且间隔分布在镜头9外侧的某一圆周安装位上，此种情况下，灯罩3也为环状结构，进而可以整体罩设在多个补光灯2上。目前的一些摄像机的补光灯采用传统的灯杯和装饰罩实现对补光灯2的罩设，上述结构存在零件结构较多，安装较为繁琐的问题，灯杯和装饰罩叠置在镜头9的投射方向上，进而会在该方向上占据较大的空间，使得补光灯2无法更近距离地靠近摄像机的前部摄像端，导致遮光角较小，而采用单一结构的灯罩3可以更容易设计成较小的体积，进而减小对上述空间的占用，也便于安装。优选的，本申请实施例中，补光灯2可以为红外补光灯。
阻光隔离件1夹设在前端罩8和透明罩7之间，为了提高隔离效果，阻光隔离件1通常为弹性较好的材料制成，即阻光隔离件1可以为弹性阻光件，弹性阻光件能通过弹性变形实现较好的隔离效果，避免光线从透明罩7与阻光隔离件1的接触面透出。具体的，阻光隔离件1可以为EVA(ethylene-vinyl acetate copolymer，乙烯-醋酸乙烯共聚物)结构件。
本申请实施例公开的摄像机可以是半球摄像机，在摄像机为半球摄像机的前提下，透明罩7为半球透明罩，如图11所示。当然，本申请实施例公开的摄像机不局限于半球摄像机，还适用于采用圆环状的阻光隔离件尺寸增大 而对补光灯的补光产生遮挡影响的其它种类的摄像机。
经过验证，本申请实施例公开的摄像机的视场角可以达到150°以上，满足了市场对摄像机的广角性能的要求。
本申请提供一种实施例采用下述技术方案：
摄像机，包括透明罩、前端罩、镜头、补光灯和阻光隔离件，其中，所述前端罩、所述镜头、所述补光灯和所述阻光隔离件均位于所述透明罩内；所述镜头安装在所述前端罩内，所述前端罩设置有避让所述镜头的避让孔，所述补光灯设置在所述镜头的外侧，所述阻光隔离件围绕所述镜头的外侧，且夹设在所述前端罩和所述透明罩之间，以隔离所述补光灯和所述镜头，所述阻光隔离件的横截面的内轮廓形状为长方形。
可选的，上述摄像机中，所述前端罩的外侧设置有前端板，所述补光灯安装在所述前端板上。
可选的，上述摄像机中，所述前端板为穿过所述前端罩的侧壁，且与所述前端罩内的电源组件电连接的PCB板。
可选的，上述摄像机中，还包括灯罩，所述灯罩罩设在所述补光灯上。
可选的，上述摄像机中，所述补光灯为红外补光灯。
可选的，上述摄像机中，所述阻光隔离件为弹性阻光件。
可选的，上述摄像机中，所述阻光隔离件为EVA结构件。
可选的，上述摄像机中，所述透明罩为半球透明罩。
本申请实施例公开的摄像机中，将圆环状的阻光隔离件更改为横截面为正方形的阻光隔离件，在视场角度增大的情况下，横截面为正方形的阻光隔离件不会对补光灯的光线产生遮挡，也就不会影响摄像机的正常摄像工作。可见，本申请实施例公开的摄像机能解决目前的摄像机在镜头视场角增大的前提下阻光隔离件会影响补光的问题。本文中，各个可选方案中的技术特征只要不矛盾均可组合来形成方案，这些方案均在本申请公开的范围内。
本文中，各个可选方案仅仅重点描述的是与其它可选方案的不同，各个可选方案只要不冲突，都可以任意组合，组合后所形成的实施例也在本说明书所公开的范畴之内，考虑到文本简洁，本文就不再对组合所形成的实施例进行单独描述。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本申请保护的范围之内。
