Description

拍摄设备、云台装置及无人机 技术领域
本申请涉及摄影器材领域，尤其涉及一种拍摄设备、云台装置及无人机。
背景技术
相机是集光学、机械、电子一体化的产品。它集成了影像信息的转换、存储和传输等部件，具有数字化存取模式，与电脑交互处理和实时拍摄等特点。光线通过镜头或者镜头组进入相机，通过数码相机成像元件转化为数字信号，数字信号通过影像运算芯片储存在存储设备中。
随着无人机技术的发展，相机搭载到无人机上，能够获得从不同于以往的拍摄角度获得更好的照片和视频，其中，云台拍摄在特殊的拍摄场景或者拍摄需求的情况下需要加装滤光镜以满足拍摄需求。但是传统的滤光镜加装结构一般设于镜头外表面，若存在多个不同镜头时，为了保证整体拍摄设备的大小，一般只使用一个滤光镜以覆盖多个镜头区域，无法满足多个镜头同时加装不同滤光镜的需求。
发明内容
本申请提供了一种拍摄设备、云台装置及无人机，能够通过不同滤光镜效果的滤光镜获取不同的成像效果。
根据本申请的第一方面，本申请提供了一种拍摄设备，包括：

本申请施例提供了一种拍摄设备、云台装置及无人机，由于相机模组还包括至少一个滤光镜组成的滤光镜组件，其中，滤光镜组件设于影像传感器与镜筒之间，这样可以使得影像传感器能够通过不同滤光镜效果的滤光镜获取不同的成像效果，以满足拍摄设备在特殊的拍摄场景或者拍摄需求的情况下需要加装滤光镜的拍摄需求。

在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个所述特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
下面结合附图，对本申请的一些实施方式作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
本申请的拍摄设备属于摄影器材技术，用于拍摄图片及或视频，该拍摄设备可以由拍摄者手持拍摄或与云台搭配使用，也可以连同云台构成拍摄组件而搭载于载体上，其中，载体可以为任意固定的物体或可移动物体，例如，建筑物、车辆、人体、动物体等，本实施方式中，载体为无人飞行器，拍摄设备连同云台构成拍摄组件搭载于无人飞行器上可以进行航拍作业。
当无人飞行器不同的拍摄场景需要不同的滤光镜才能够得到更好的特效效果，但是现有拍摄设备由于结构空间紧，无法解决多个镜头同时加装不同滤光镜的需求，在针对不同的拍摄场景时，效果显得比较单一。因此，本申请将滤光镜设置在影像传感器与镜筒之间，可以占用更小的体积来满足针对不同镜头加装不同滤光镜的需求，同时也满足了不同拍摄场景的需要，使得用户能同时看到当前预拍摄场景的不同滤光镜效果，以便用户能直观比较哪种特效更佳，用户体验更好。
如图1至图4所示，本申请实施方式的拍摄设备100包括壳体模组10和相机模组20，壳体模组10包括透明镜片12和壳体11，壳体11具有两端呈开口的中空结构体111，透明镜片12封装在中空结构体111一端的开口处上，镜座22安装在中空结构体111内，且镜筒21的方向朝向透明镜片12。相机模组20包括影像传感器27、镜座22和至少一个安装在镜座上的镜筒21，影像传感器27和镜筒21均通过镜座22安装在中空结构体111内，且镜筒21的方向朝向透明镜片12。在本实施例中，相机模组还包括滤光镜组件，滤光镜组件包括滤光镜至少一个滤光镜23，其中，滤光镜23设于影像传感器27与镜筒22之间，以使得影像传感器27能够通过不同滤光镜效果的滤光镜23获取不同的成像效果。
由于本申请将由多个滤光镜23组成的滤光镜组件设置在影像传感器27与镜筒22之间，减少利用滤光镜安装部将滤光镜组件固定在镜筒21上，同时也不会影响滤光镜23的滤光镜效果，有效解决滤光镜多个不同的滤光镜23无法安装在结构空间紧凑的拍摄设备中的问题，不仅确保滤光镜安装的可靠性好，而且制造简单，生产成本低。另外，影像传感器27可以为CCD(Charge-Coupled Device)面传感器或CMOS(Complementary Metal Oxide Semiconductor)图像传感器等的一种。
可以理解，由于传统的拍摄设备100因空间有限而无法加装更多的滤光镜23，因此在差异较大的拍摄场景只能用同一个滤光镜，例如高空、深海、雨天或寒冷地区时，效果非常单一。而本申请将滤光镜组件设置在影像传感器27与镜筒22之间，解决了传统拍摄设备100因空间问题而无法加装滤光镜至少一个滤光镜23的问题，同时可以根据不同的地理环境、天气情况及对应的时间、光线等选择相对应的效果滤光镜，从而获得不同拍摄场景的拍摄效果，或者针对同一个拍摄对象获取不同波段的图像以供用户分析使用，以提高用户的体验效果。
在一个可选的实施方式中，如图5和图6所示，滤光镜23的数量少于或等于镜筒21的数量。
具体地，在图示实施例中，当镜筒21的数量为六个时，滤光镜23的数量也为6个，即每个镜筒21上均安装有一个滤光镜23。这样便可以通过选择不同的镜筒21获得镜筒21上对应的滤光镜23，针对不同需求可以使用不同镜筒 21和对应滤光镜23。能够直观地选择符合当前场景的滤光镜效果，或者进行多个滤光镜效果比较后再进行选择需要合适的滤光镜23，也可以在最短时间内选择合适的滤光镜23，节约拍摄时间，提高的便利性。其中，拍照场景可以为人像、美食、建筑、风景、夜景、花卉、农田、植物、运动、雨天、阴天、晴天中的其中一种或多种。
此外，在另一个实施例中，当镜筒21的数量为六个时，滤光镜23的数量也可以为五个、四个或三个等，即两个或三个镜筒21共同使用一个滤光镜23，这样也可以通过不同的滤光镜23中得到影像传感器27所拍摄目标事物的成像效果。例如，滤光镜组件可以包括“黑白”、“单色”、“色调”和“褪色”四种滤光镜23时，那么影像传感器27获得的成像效果可以为上述四种滤光镜23的其中一种成像效果，也可以为四张分别对应上述四个滤光镜23每一个滤光镜效果对应单独的成像效果。再例如，拥有5个不同滤光镜23的滤光镜组件包括RGB(红绿蓝三原色)滤光镜，红光滤光镜，红外滤光镜，绿光滤光镜，近红外滤光镜，可以获取不同光线波段的图像，以供用户使用。
在一个可选的实施方式中，如图5所示，镜座22上设有滤光镜安装部225，滤光镜安装部225的数量与镜筒21的数量相匹配，且滤光镜安装部225的位置与镜筒21安装在镜座22后的位置相对应，在本实施例中，滤光镜23对应安装在滤光镜安装部225上，结构简单，安装方便。
具体地，滤光镜安装部225为设置在镜座22上的滤光镜容置槽，滤光镜容置槽的形状及大小与滤光镜23的形状及大小相适配，以使得滤光镜23刚好可以放进滤光镜容置槽中。
在本实施例中，如图5和图11所示，滤光镜容置槽225与滤光镜23的形状均呈方形，这样不仅便于滤光镜23位置的固定，同时也便于滤光镜容置槽与滤光镜23的加工。
在一个可选的实施方式中，如图6所示，相机模组20还包括电路板26，电路板26用于承载影像传感器27，在本实施例中，电路板26安装在镜座22背对镜筒21的一端，影像传感器27与镜筒21的光轴对正设置。
具体地，如图8和图13所示，镜座22上还设有电路板定位销226，电路板26上设有电路板定位孔262，当电路板26安装在镜座22上，电路板固定螺丝261直接穿过电路板通孔263后将电路板26固定在镜座22上，其中，电路 板定位孔262与电路板定位销226匹配，以确保影像传感器27与镜筒21的光轴能够对正。
在一个可选的实施方式中，如图5、图6和图12所示，滤光镜安装部225设置在镜座22靠近电路板26的一端，其中，相机模组20还包括间隔件24，间隔件24上设有间隔件通孔241，间隔件24用于确保影像传感器27与滤光镜23的间距，同时又可以起到减震作用。在本实施例中，间隔件24采用柔性或者弹性材料制成，例如橡胶或泡棉等，其中，间隔件24安装在电路板26与滤光镜23之间，影像传感器27刚好透过间隔件通孔241与镜筒21的光轴能够对正。
在一个可选的实施方式中，滤光镜23通过胶粘剂粘接在滤光镜安装部225上，或滤光镜23直接嵌合在滤光镜安装部225上。
组装时，首先将滤光镜23安装在滤光镜安装部225上，而后将间隔件24放入滤光镜安装部225中，最后将电路板26安装在镜座22上。其中，电路板26安装在镜座22时，确保电路板定位孔262与电路板定位销226之间的匹配，这样才能保证影像传感器27、间隔件通孔241与镜筒21三者的位置关系，进一步确保了影像传感器27与镜筒21的光轴对正。
在一个可选的实施方式中，如图1至图3所示，镜座22与中空结构体111之间连接有密封组件30，密封组件30由密封圈31和密封压片32组成，密封组件30用于将镜筒21密封在镜座22、透明镜片12和中空结构体111三者所围成的密封腔内。
由于本申请通过密封组件30将镜筒21密封在镜座22、透明镜片12和中空结构体111三者所围成的密封腔内，当拍摄设备100位于高温高湿的环境中，外部环境中的水汽不会进入密封腔内，从而避免了镜筒21前端靠近镜筒21一端面的透明镜片12在容易起雾的问题。此外，由于密封组件30由密封圈31和密封压片32组成，密封圈31通过密封压片32安装在中空结构体111中，解决了传统密封圈31因空间原因而无法压合的问题，同时也提高了密封腔内的密封效果，便于密封圈31的装配。
可以理解，当传统的拍摄设备100应用于差异较大的工作环境下，例如高空、深海、雨天或寒冷地区时，当镜座22、透明镜片12和中空结构体111三者所围成的密封腔不够密封时，外部水分子容易通过间隙进入密封腔内，其中， 拍摄设备100一般具有体积小、发热大等特点。因此，在拍摄设备100的内部温度高于外界温度，拍摄设备100内部的水分子遇到低温的透明镜片12发生液化，在透明镜片12靠近拍摄设备100内部的表面凝结成雾状的水滴，当光线从外界进入相机模组20时，穿过水滴造成光线发生折射、反射等变化，影响拍摄效果。本申请将透明镜片12封装在中空结构体111一端的开口处上，，镜座22通过密封组件30连接至中空结构体111的另一端，使得镜筒21能够密封在镜座22、透明镜片12和中空结构体111三者所围成的密封腔内，从而彻底解决外部环境中的水汽进入密封腔内的问题，避免了镜筒21前端在靠近镜筒21一端面的透明镜片12容易起雾的问题。
在一个可选的实施方式中，如图14至图16所示，中空结构体111上设有固设部112和与固设部112具有第一预设距离的安装部115，其中，透明镜片12通过胶粘剂粘接在固设部112上，密封组件30设置在安装部115与镜座22之间。
具体地，透明镜片12与固设部112通过烘烤胶泥固定；或透明镜片12通过双面胶固定在固设部112上；或透明镜片12通过紫外线固化胶密封在固设部112上，这样可以将透明镜片12完全封装在固设部112上，也确保了透明镜片12与固设部112安装后的密封性。
其中，第一预设距离可以为任何长度，其目的主要为了使得镜筒21能够位于透明镜片12的内侧且与透明镜片12存在预设的间隙，同时又可以确保镜座22能够将密封组件30压合在安装部115上，使得镜筒21能够完全密封在镜座22、透明镜片12和中空结构体111三者所围成的密封腔内，避免拍摄设备100在高温高湿的环境中，外部环境中的水汽不会进入密封腔内，造成镜筒21前端在靠近镜筒21一端面的透明镜片12容易起雾的问题。
在一个可选的实施方式中，安装部115非对称设置在中空结构体111中，密封圈31设有密封圈通孔311和密封圈凹槽312，其中，密封圈凹槽设置在密封圈31的外侧壁上，且密封圈凹槽312的形状与对应位置的安装部115的形状相匹配，这样使得密封圈31能够通过密封圈凹槽312安装在中空结构体111中，便于密封圈31的安装，避免密封圈31在中空结构体111中出现滑动问题，影响密封圈31装配后的密封性。
在本实施例中，安装部115在中空结构体111的内侧是非对称设置，例如， 中空结构体111具有四个内侧面，每两个内侧面相对设置，而安装部115在其中两个相对的内侧面的位置是不同的或非对称的，这样可以避免密封圈31在中空结构体111内出现装反或装错的问题，起到防呆作用，同时也使得密封圈能够进行正对性的设计，如中空结构体111的上侧面由于结构问题导致制造公差的不稳定，需要密封圈在该位置的厚度有所变化等。
具体地，如图14至图16所示，壳体11包括壳体小端11a和与壳体小端11a连接的壳体大端11b，其中，中空结构体111从壳体小端11a的一端面贯穿至壳体大端11b的一端面，固设部112设置在壳体小端11a的端面上。在本实施方式，固设部112为开设在壳体小端11a端面上内凹的槽体，槽体的形状及大小与透明镜片12的形状及大小相适配，以便透明镜片12能够稳固的固定在固设部112上。其中，安装部115包括环设在中空结构体111内侧壁的环缘1152和凸设在中空结构体111内侧壁中的安装座1151，安装座1151与环缘1152具有第二预设距离，镜座22上设有凸缘221，凸缘211的位置与环缘1152的位置相对应，以使得密封组件30两个相对的端面能够分别抵接在环缘1152和凸缘221的一端面上，即凸缘221将密封组件30压合在环缘1152上，确保镜座22、透明镜片12和中空结构体111三者所围成密封腔的密封性。
在本实施方式中，第一预设距离是指固设部112与安装座1151的最远距离，第二预设距离是指环缘1152与安装座1151的最远距离，其中，第一预设距离大于镜筒21的长度，第二预设距离小于密封圈31的厚度。在本实施例中，凸缘221上设有压片槽2211，压片槽2211的深度与密封压片32的厚度相匹配，即当密封圈31放入中空结构体111内，密封圈31的一端面与环缘1152的端面接触后，将密封压片32放入中空结构体111内，用于固定密封圈31。
具体地，密封压片32放置在密封压片32的上端，而后通过压片槽2211与密封压片32的配合将镜座22安装在中空结构体111内，这样不仅可以确保镜座22能够将密封圈31压合在环缘1152上，使得镜筒21可以完全密封在密封腔内，而且也解决了传统拍摄设备100中密封圈31装配困难的问题，即密封圈31因空间原因无法压合并进行密封的问题。因此，采用以上技术方案后，不仅解决了密封圈31因空间不足的装配问题，同时也提高了密封圈31在镜座22、透明镜片12和中空结构体111三者所围成密封腔的密封效果。
在一个可选的实施方式中，如图4和图17所示，密封圈31的一内侧壁具 有弧形外凸结构313，密封压片32安装在弧形外凸结构313的一侧。具体地，镜座22在朝向透明镜片12的一侧设有镜筒安装部222，镜筒安装部222的内径与镜筒21的外径相适配，以使得镜筒21能够可拆卸安装在镜筒安装部222上，其中，镜筒安装部222凸设在镜座22上，且镜筒安装部222的形状呈圆柱形，弧形外凸结构313内凹的直径与镜筒安装部222的外径相适配，以使得密封圈31能够卡接在镜筒安装部222上，间接提高了密封圈31的密封效果。此外，为了方便密封组件30的设计，将密封压片32的安装位置设置在弧形外凸结构313的一侧，压片槽2211设置在凸缘221与弧形外凸结构313相对的位置上。
在一个可选的实施方式中，如图18和图19，密封压片32上设有至少一个压片通孔321，凸缘221上设有与压片通孔321数量匹配的压片定位销2212，压片定位销2212的位置与压片通孔321的位置相对应。
在本实施例中，压片通孔321和压片定位销2212的数量均为两个，两个压片通孔321分别设置密封压片32两侧，当镜座22通过安装座1151安装在中空结构体111中，凸缘221上的压片定位销2212刚好穿过压片通孔321以将密封压片32固定，进而实现对密封圈31进行固定。
在一个可选的实施方式中，如图16、图18和图19所示，安装部115在密封压片32的位置上凸设有安装座凸台1155，密封压片32上设有压片凸台322，压片凸台322安装在安装座凸台1155与密封圈31之间，起到导向及限位作用，即只需要控制压片凸台322紧靠在安装部115在安装座凸台1155下方的侧壁，即可确保密封压片32与密封圈31的相对位置，避免将镜座22固定在安装座1151时，压片定位销2212刚好可以穿过压片通孔321，避免因为密封压片32的安装位置不对而造成反复的安装，造成装配成本的浪费在一个可选的实施方式中，拍摄设备100还包括具有螺柱的镜座锁紧件25，其中，螺柱上设有外螺纹，凸缘221上设有凸缘穿孔223，安装座1151上开设有安装座螺孔1153，螺柱穿过凸缘穿孔后223与安装座螺孔1153螺纹连接，用以将镜座22固定在安装座1151上，采用螺纹连接的固定方式，不仅便于安装与拆卸，而且固定也非常牢固。
在一个可选的实施方式中，如图18和图19所示，安装座1151上设有安装座定位销1154，凸缘221上设有凸缘定位孔224，凸缘定位孔224的位置与安 装座定位销1154的位置相对应。
具体地，如图8、图9和图19所示，安装座定位销1154和凸缘定位孔224的数量均为两个，两个凸缘定位孔224分别设置在镜座22呈中心对称的两个对角上，以便可以将镜座22准确的安装在安装座1151上，确保相机模组20与壳体11的相对位置。
在一个可选的实施方式中，如图4和图14，壳体11在靠近透明镜片12的一端设有镜筒固设部113，镜筒固设部113的形状及大小与镜筒21的形状及大小相适配，固设部112设置在镜筒固设部113的外侧，这样不仅可以确保镜筒21能够位于透明镜片12内侧并透过透明镜片12活动外部环境的信息，同时也能够确保镜筒21安装的稳定性，尤其是拍摄设备100与外部事物碰撞时，镜筒21容易脱离镜筒安装部222或者造成镜筒21的松动等。
在本实施例中，如图3和图14，镜筒21的数量为六个，六个镜筒固设部113呈两排三列间隔设置在壳体11上。具体地，各镜筒固设部之间等间距间隔设置，以充分利用壳体11的内部空间，减少拍摄设备100的体积，使得整个拍摄设备100的结构显得更为紧凑。
在一个可选的实施方式中，如图1、图2和图14，透明镜片12为玻璃镜片，和/或壳体11采用塑料材料制成。可以理解，透明镜片12设置在壳体模组10的外部，以防止灰尘和水分进入壳体模组10，并能防止外界物体损坏壳体模组10内的相机模组20。
如图20所示，本申请还提供一种云台装置200，包括云台本体201和上述的拍摄设备100，其中，云台本体201包括支架2012和至少一个转动电机2011，支架2012通过其中一个转动电机2011与拍摄设备100连接。
具体地，如图3和图4所示，拍摄设备100上设有连接部114，用于连接转动电机2011。在本实施例中，连接部114为设置在壳体11的安装槽，安装槽的形状及大小刚好能够与转动电机2011的转动部卡接，以便于拍摄设备100的安装与拆卸。
如图21所示，本申请还提供一种无人机300，包括机身301、动力组件302和上述的云台装置200，动力组件302用于为无人机300提供飞行动力，云台装置200安装在机身301上。
