Description

镜头装置、拍摄设备及无人机 技术领域
本发明涉及电子设备技术领域，尤其涉及一种镜头装置、拍摄设备及无人机。
背景技术
拍摄设备具有外壳及组装于外壳内的镜头模组，在外壳与镜头模组相对的位置设有透明镜片，以使得外部的光线透射至镜头模组处。在镜头模组的工作过程中，其感光及图像处理等部位会产生大量的热量，该部分热量以热传递及热辐射等形式通过拍摄设备的外壳进行散发。
在空气中存在水汽，因此在拍摄设备的内部空间的空气中同样存在水汽。在镜头模组工作过程中，其产生的热量使得外壳的内部与外部存在较大温差，特别是小型拍摄设备，其在镜头模组与外壳之间的空间小，温差更加明显。
其中，透明镜片远离镜头模组的发热部位，透明镜片的温度低于镜头模组附近的温度。因而，拍摄设备的内部空气中的水汽易在透明镜片的内侧表面处凝结。由于水汽的凝结位置处于拍摄设备内部，不易清除。而且，水汽凝结在透明镜片上，直接影响光线的透射效果，导致拍摄设备的拍摄效果差。

如图1及图2所示，镜头装置应用于拍摄设备，该拍摄设备包括主机60，镜头装置组装至主机60，该拍摄设备用以拍摄及录制图像等。镜头装置包括组装至主机60的镜头模组10、固连至主机60的壳体20、及密封连接至壳体20的镜片组件30。其中，镜头模组10包括与主机60固连的基座部11及凸出基座部11的镜头部12。
镜片组件30与镜头模组10分别位于壳体20的两端，镜片组件30与镜头模组10相对设置，具体为，镜头部12与镜片组件30正对设置，光线可通过镜片组件30进入镜头模组10。镜头模组10至少部分处于壳体20内并向镜片组件30方向延伸，在镜片组件30和镜头模组10之间形成封闭的收容空间21。
在镜片组件30与镜头模组10之间形成封闭的收容空间21可包括以下方式：
1、镜片组件30直接与镜头模组10密封连接，例如：镜片组件30向镜头模组10方向延伸并包裹镜头部12的外侧壁上，在镜头部12与镜片组件30之间形成封闭的收容空间21。
2、镜片组件30结合壳体20与镜头模组10密封连接。例如，壳体20向镜头模组10方向局部凸出并与镜头模组10之间实现密封连接，镜头部12、壳体20及镜片组件30之间形成封闭的收容空间21。
在镜头模组10与镜片组件30之间形成封闭的收容空间21，使镜头部12处于该收容空间21内，通过控制该收容空间21的水汽含量，减小空气中水汽在镜片组件30上的起雾现象或凝结，稳定拍摄效果。而控制空气中水汽含量的方式可包括以下方式：在干燥环境下装配；或在该封闭的收容空间21内设置用以 吸收水汽的吸附件50，如吸湿片、吸湿剂等。
以下以镜片组件30结合壳体20与镜头模组10密封连接形成封闭的收容空间21为例进行说明。
如图1及图2所示，壳体20包括主体部22及贯穿主体部22的容纳腔23，壳体20呈中空的环形薄壁结构。镜头模组10位于容纳腔23的一端，且至少部分向容纳腔23内延伸，如镜头部12向容纳腔23内延伸。镜片组件30封闭在容纳腔23的另一端并与主体部22密封连接。
镜头模组10与镜片组件30分别位于容纳腔23的两端，通过封闭至少部分容纳腔23以形成封闭的收容空间21，从而使镜头模组10的镜头部12处于收容空间21内并与镜片组件30相对设置。其中，在相邻两零件的接触面之间通过密封元件进行密封，如采用橡胶材料制成的密封圈、O形圈等；或填充密封剂进行密封，如密封胶等；或通过密封结构进行密封，如螺纹连接等。通过设置零件接触面之间的密封结构，避免收容空间21内的空气与外界的空气进行流动，保持收容空间21内的水汽含量稳定，保持镜头模组10的拍摄效果稳定。
壳体20用以与主机60固连，其罩设或至少部分罩设镜头模组10，其外径大于镜头模组10的外径。为使壳体20与镜头模组10之间形成密封，可选地，壳体20包括向容纳腔23凸出的密封部24，密封部24抵接至镜头模组10并与镜头模组10之间形成密封连接。例如，密封部24向容纳腔23内延伸并抵接至基座部11。密封部24呈中空的管状套设于镜头部12外侧，且密封部24的端部与基座部11的表面之间密封连接。
镜头装置还包括由弹性材料制成的第一密封件40，该第一密封件40组装于密封部24的端部，两者可通过胶接连接。或在密封部24上开设有凹槽，第一密封件40匹配组装至凹槽。当壳体20组装至主机60时，密封部24推抵第一密封件40挤压至镜头模组10，以使得第一密封件40密封贴合至镜头模组10。
第一密封件40可采用橡胶等弹性材料制成，在受到密封部24与镜头模组10之间的相互挤压力时，第一密封件40发生弹性形变，以使密封部24与镜头模组10之间密封连接，实现壳体20与镜头模组10之间的密封，安装方便，密 封效果好。
如图1及图2所示，镜片组件30组装至壳体20并封闭容纳腔23的另一端，其与壳体20之间的接触面需进行密封连接。镜片组件30包括连接件31及组装于连接件31的透明镜片32，连接件31组装至壳体20且透明镜片32与镜头模组10正对。透明镜片32与连接件31固定连接，在连接件31上套设有第二密封件33，第二密封件33由弹性材料制成，如采用橡胶材料制成等。
在连接件31组装至壳体20的过程中，第二密封件33随连接件31移动，并被连接件31推抵挤压至壳体20，第二密封件33产生弹性形变并密封贴合至壳体20，使得连接件31与壳体20之间的连接部位处于密封状态，进而避免收容空间21内的空气与外界空气流通，密封效果好。
连接件31与壳体20连接，在一实施例中，连接件31包括台阶部311及凸设于台阶部311的螺纹部312，该螺纹部312设有螺纹结构，相应地，在壳体20上设有对应的螺纹结构，连接件31与壳体20螺纹连接。台阶部311的外径大于螺纹部312的外径，第二密封件33套设于螺纹部312，并位于螺纹部312与台阶部311的相交处。可选地，在螺纹部312上开设有凹槽，第二密封件33位于凹槽内，以使第二密封件33处于预设位置。当连接件31连接至壳体20时，螺纹部312沿壳体20旋转，且台阶部311推抵第二密封件33密封贴合至壳体20的端面。
通过设置第二密封件33于密封连接件31与台阶部311的接合处，避免空气从两者的螺纹面之间进行流通，密封方便。当然，通过第二密封件33进行密封连接仅为其中一种密封方式，两者的密封方式不限与此。例如可以在连接件31与壳体20的结合面处涂覆密封胶等，也可有效密封以隔绝收容空间21与外界的空气流通。
透明镜片32组装至连接件31，两者之间具有结合面。在一实施例中，连接件31还包括凸出台阶部311的镜片部313及自镜片部313凹陷的凹槽部314，透明镜片32与凹槽部314胶接连接。透明镜片32与凹槽部314之间的结合面涂覆粘结剂，使两者的接触面密封。
当然，透明镜片32与连接件31通过胶接方式进行密封仅为其中一者密封方式，两者的密封方式不限与此。例如透明镜片32与连接件31之间设置密封圈，设置锁定件推动透明镜片32抵紧密封圈，也可有效实现透明镜片32与连接件31之间的密封，以隔绝收容空间21与外界的空气流通。
通过镜头模组10、壳体20及镜片组件30之间的密封连接，使得镜头部12处于封闭的收容空间21内，控制空气中的水汽含量，可降低或避免水汽在镜片组件30凝结及起雾现象，保持镜头模组10的成像效果稳定。
如图1及图3所示，可选地，镜片组件30还包括套设于连接件31的保护罩34，保护罩34开设有通孔341，通孔341正对透明镜片32。在连接件31外套设以保护罩34，该保护罩34用以避免外界直接冲击到透明镜片32，对镜片组件30的保护效果好。而且，保护罩34的外形美观，如将通孔341的孔壁设为喇叭状开口，和/或将其壁面设为台阶状结构；在保护罩34的外周面上开设花纹等。
值得一提的是，该拍摄设备可应用于无人机，该无人机包括飞行主体，拍摄设备组装至飞行主体；该无人机还包括云台，该拍摄设备组装至云台。
在不冲突的情况下，上述的实施例及实施例中的特征可以相互组合。以上仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明保护的范围之内。
