The invention disclose a three-section empennage, which comprises first empennages on the two sides, a second empennage in the middle, a stretching mechanism and a lifting mechanism, the stretching mechanism comprises a driving assembly and a swing rod assembly, the second empennage is fixed to the upper portion of the driving assembly, and the first empennages are fixed to the swing rod assembly; the driving assembly drives the swing rod assemblies on the two sides and drives the first empennage to be unfolded towards the two sides or folded towards the middle, when the first empennage is unfolded, the first empennage is connected with the second empennage, and when the first empennage is folded, the second empennage is located below the first empennage. The driving assembly further comprises a worm and gear assembly which can drive the first empennage and the second empennage to incline integrally. The stretching mechanism is fixedly connected with the lifting mechanism through a lifting block, and the lifting mechanism drives the first empennage and the second empennage to move up and down. The three-section empennage can be lifted along with the speed, automatically adjust the angle and be opened in a three-section mode, the area of the empennage is further increased, the influence of wind power on a high-speed running vehicle is reduced, and a better balance effect is achieved.
本发明公开了一种三段尾翼,包括两侧的第一尾翼、中间的第二尾翼、伸展机构和升降机构,伸展机构包括驱动组件和摆杆组件,第二尾翼固定在驱动组件上方,第一尾翼固定在摆杆组件上;驱动组件带动两侧摆杆组件,带动第一尾翼向两侧展开或向中间合拢,第一尾翼展开时,第一尾翼与第二尾翼相接,第一尾翼合拢时,第二尾翼位于第一尾翼下方;驱动组件还包括蜗轮蜗杆组件,可带动第一尾翼、第二尾翼整体倾斜;伸展机构与升降机构通过升降块固定连接,升降机构带动第一尾翼、第二尾翼上下移动。三段尾翼可实现随速升降,自动调节角度,三段式打开,进一步增大尾翼面积,减少风力对高速行驶的汽车的影响,起到更好的平衡作用。
