The invention relates to the technical field of tandem double-rotor helicopters, and discloses a tandem double-rotor helicopter transmission mechanism which comprises a helicopter body unit, a transmission unit, a double-rotor approaching unit and a double-rotor blade telescopic unit, the helicopter body unit comprises a helicopter body, and a helicopter body cover plate is arranged above the helicopter body; the helicopter body and the helicopter body cover plate are integrally connected, and two symmetrical mounting brackets are arranged at the bottom of the helicopter body. According to the unmanned aerial vehicle, a flight person starts a bidirectional electric push rod, at the moment, the bidirectional electric push rod can pull a guide sliding rod to slide on a guide sliding groove, and when the guide sliding rod moves, a connecting rod can be driven to move; when a connecting rod moves, a movable plate can be driven by a fixing ring, a positioning plate and a positioning rod to horizontally move under the assistance of a first sliding rail, so that two rotating rods in the double-rotor approaching unit can be close to each other.
本发明涉及纵列式双旋翼直升机技术领域,公开了一种纵列式双旋翼直升机的传动机构,包括直升机本体单元、传动单元、双旋翼靠近单元和双旋翼浆叶伸缩单元,直升机本体单元包括直升机本体,直升机本体上方设置有直升机本体盖板,直升机本体和直升机本体盖板一体化连接,直升机本体底部设置有两个相互对称的安装支架。本发明,飞行人员通过启动双向电动推杆,此时双向电动推杆能够拉动导向滑杆在导向滑槽上进行滑动,当导向滑杆移动的时候将能够带动连接杆进行移动,当连接杆移动的时候将能够通过固定环、定位板和定位杆带动移动板在第一滑轨的辅助下进行水平移动,因此能够让双旋翼靠近单元中的两个旋转杆相互靠近。
