A novel high-storage-ratio orderly-unfolding whip antenna unfolding mechanism, provided by the present invention, comprises a shell, a pin puller, a rotating disc, a shaft, an antenna unit and a vortex spring. The antenna unit is a whip antenna with an arched section after being unfolded, a through hole matched with the shaft is formed in the center of the rotating disc, a pin shaft matching holematched with the pin puller and used for releasing the rotating freedom degree of the rotating disc is formed at the upper portion of the rotating disc, and an antenna winding section with the side face being a protruding cambered surface is arranged in the middle of the rotating disc. The cambered surface corresponds to the arched section of the antenna unit, the antenna unit is integrally woundon the antenna winding section, and after the rotating disc and the shaft are assembled, the assembled rotating disc and the shaft are integrally mounted in the shell. The vortex spring sleeves the shaft, the shaft can be driven to rotate, and the rotating disc is driven to rotate, so that the antenna unit is released and unfolded. The volute spiral spring is adopted to drive the rotating shaft torealize the one-dimensional ordered unfolding of the whip antenna, the unfolding process is stable and controllable, the unfolding precision is high, and the problem of low rigidity of the antenna due to large size and light weight is solved by using a novel unfolding mode and the arched section.
本发明提出一种新型高收纳比有序展开鞭天线展开机构,包括壳体、拔销器、旋转盘、轴、天线单元和涡簧;天线单元为展开后截面呈拱形的鞭天线;旋转盘中心具有与轴配合的通孔,上部具有与拔销器配合的、用于释放旋转盘旋转自由度的销轴配合孔,中部具有侧面为突出弧面的天线缠绕段,弧面与天线单元截面拱形对应;天线单元整体缠绕在天线缠绕段上;旋转盘与轴装配好后,整体安装在壳体内;涡簧套在轴上,能够驱动轴转动,并带动旋转盘转动,将天线单元释放展开。本发明采用涡卷弹簧驱动旋转轴实现鞭状天线的一维有序展开,展开过程平稳可控,展开精度高,并且通过使用新型展开方式以及拱形截面解决天线因尺寸大、重量轻引起的低刚度问题。
