The invention relates to the technical field of underwater vehicles, and provides an attached fin unfolding device which comprises an attached fin, a folding module and a horizontal fin plate, a containing groove is formed in the upper portion of the horizontal fin plate, the bottom of the horizontal fin plate is fixedly connected with the outer side face of a shell, the folding module is fixedly installed at the tail end of the horizontal fin plate, and one end of the attached fin is coaxially assembled in the folding module; the folding module comprises an attached fin mounting seat, a rotating shaft, a first rotating seat, a lining cover, a second rotating seat, an end cover and an elastic assembly, and when the attached fin rotates towards the horizontal fin plate along the folding module, the attached fin can be folded and stored in a containing groove of the horizontal fin plate; the elastic assembly synchronously rotates to store energy when the attached fin rotates towards the horizontal fin plate and can make the attached fin rotate out of the containing groove along the folding module away from the horizontal fin plate to be unfolded. The structure of the device can be simplified, the failure rate can be reduced, the structural compactness and operation reliability of the device can be obviously improved, the control pressure and difficulty of an aircraft control system can be reduced, and the fin area increasing rate can be obviously improved.

    本发明涉及水下航行器技术领域,提供一种附鳍展开装置,包括附鳍、折叠模块和水平鳍板,水平鳍板的上部设置容纳槽,水平鳍板的底部与壳体外侧面固定连接,折叠模块固定安装在水平鳍板的尾端,附鳍的一端同轴心装配在折叠模块内,折叠模块包括附鳍安装座、转轴、第一旋转座、衬套盖、第二旋转座、端盖以及弹性组件,当附鳍沿折叠模块向水平鳍板旋转时,能够折叠收纳于水平鳍板的容纳槽中,弹性组件在附鳍向水平鳍板旋转时同步旋转而储能并能够使附鳍沿折叠模块远离水平鳍板从容纳槽中旋出展开。本发明可以简化装置的结构,降低故障率,显著装置的结构紧凑度及运行可靠性,减轻航行器控制系统的控制压力和难度,显著提高鳍板面积增大率。
