The invention discloses a folding and unfolding device and a folding and unfolding method for a lift system of an unmanned aerial vehicle. The folding and unfolding device comprises corresponding sections of a vehicle body structure, a movable bracket, a bracket driving mechanism and the lift system, one end of the movable bracket is connected with a corresponding section of the airframe structure, and the other end is connected with the lift system which moves along with the movable bracket; the support driving mechanism is connected with the movable support, and power is provided by the movement form of the movable support. The folding and unfolding device has at least two working positions including a starting position and a storage position. According to the technical scheme, the problem that the endurance time and the maximum flight speed of the whole machine are seriously influenced due to the fact that a lift motor does not run any more during horizontal flight of an existing composite vertical take-off and landing unmanned aerial vehicle is still large in resistance is solved.

    本发明公开一种用于无人机升力系统的收放装置和收放方法,包括机体结构相应分段、可运动支架、支架驱动机构和升力系统;可运动支架一端与机体结构相应分段连接,另一端连接与升力系统,升力系统跟随可运动支架的运动;支架驱动机构与可运动支架连接,可运动支架的运动形式提供动力;收放装置具有至少两种工作位置,包括启动位置和收纳位置。本发明的技术方案解决了现有复合构型垂直起降无人机,由于水平飞行时虽然升力电机已经不再运转,但仍然会产生较大的阻力,从而导致严重影响整机的续航时间与最大飞行速度的问题。
