The unmanned helicopter comprises a helicopter body, a main rotor wing located at the top of the helicopter body, a tail beam arranged on the helicopter body and a tail rotor wing arranged on the tailbeam, the root of the tail beam is connected with the helicopter body through a first rotating joint, and a locking mechanism is further arranged between the root of the tail beam and the helicopterbody; the free end of the tail beam can rotate around the first rotating joint, and when the free end of the tail beam rotates to a first preset position, the free end of the tail beam is attached tothe side portion of the fuselage; and when the free end of the tail beam rotates to a second preset position, the tail beam and the fuselage are located at the matching position in the flying state, and the locking mechanism is used for locking the root of the tail beam located at the second preset position to the fuselage. When the unmanned helicopter is not used, the tail beam can be folded andstored towards the side portion of the helicopter body, the overall size of the unmanned helicopter is greatly reduced, and therefore the unmanned helicopter is more convenient to carry in the non-usestate.

    本发明公开了一种无人直升机,包括机身、位于机身顶部的主旋翼、设置在机身上的尾梁和设置在尾梁上的尾旋翼,尾梁的根部与机身之间通过第一转动关节连接,且尾梁的根部与机身之间还设置有锁紧机构;尾梁的自由端能够绕第一转动关节转动,且当尾梁的自由端转动至第一预设位置时,尾梁的自由端与机身的侧部贴合;当尾梁的自由端转动至第二预设位置时,尾梁与机身处于飞行状态下的配合位置,且锁紧机构用于将处于第二预设位置的尾梁的根部锁紧在机身上。该无人直升机在不使用状态下,可以实现了尾梁向机身的侧部折叠收纳,大大缩减了无人直升机的整体尺寸,从而使得无人直升机在非使用状态下携带更加方便。
