The invention discloses a combined oblique tension spring airfoil unfolding mechanism, and belongs to the technical field of machinery. The cabin comprises a cabin body 1, a wing surface 2, a rotating shaft 3, a locking mechanism 4, a tension spring 5 and a tension spring shaft 6. When the mechanism is mounted, the locking mechanisms 4 are mounted in the airfoils 2, and then the four airfoils 2 are fixed on the cabin body 1 of the aircraft through the rotating shafts 3. Hook rings at the two ends of the four sets of tension springs 5 penetrate through the four tension spring shafts 6 correspondingly, the four tension springs 5 and the four tension spring shafts 6 are connected into a flexible whole, and finally the tension springs 5 and the tension spring shafts 6 are sequentially connected with the mounting structures at the bottoms of the four sets of airfoils 2. According to the combined oblique tension spring airfoil unfolding mechanism, the annular structure space in a cabin is fully utilized, and no protrusion exists outside an aircraft after installation.
组合式斜向拉簧翼面展开机构,属于机械技术领域。本发明包括:舱体1、翼面2、转轴3、锁紧机构4、拉簧5、拉簧轴6。机构安装时,先将锁紧机构4安装在翼面2内,再通过转轴3将四组翼面2固定在飞行器的舱体1上。将四组拉簧5两端的勾环分别穿过四个拉簧轴6,将四个拉簧5和四个拉簧轴6连接成为一个柔性整体,最终拉簧5和拉簧轴6组件依次与四组翼面2底部的安装结构相连。本发明组合式斜向拉簧翼面展开机构充分了利用舱体内部的环向结构空间,且安装后飞行器外部无凸起。
