The cabin door folding and unfolding device comprises a shifting rod and a shifting fork, the shifting rod is arranged on a supporting column of an undercarriage, the shifting fork is arranged on the cabin door, the shifting rod moves along with the undercarriage, and in the process that the cabin door is folded or unfolded, the shifting rod makes contact with the shifting fork and drives the shifting fork to move. Therefore, the cabin door is driven by the shifting rod arranged on the undercarriage to retract and release, and the cabin door moves along with the shifting fork, so that the cabin door retracting and releasing device adopting the structure can retract and release the cabin door without arranging a special driving device for the cabin door, the weight is reduced, the flight efficiency of the unmanned aerial vehicle is improved, and the cabin door retracting and releasing device is simple in structure and convenient to use. And invalid actions of cabin door folding and unfolding are reduced, the space utilization rate of the unmanned aerial vehicle is improved, and good manufacturability and economical efficiency are achieved.
本申请公开了一种舱门收放装置,用于收放舱门,舱门收放装置包括:拨杆和拨叉,拨杆设于起落架的支柱上,拨叉设于舱门,拨杆随起落架运动,在舱门收起或放下的过程中,拨杆与拨叉接触并驱动拨叉运动。这样,舱门的收放运动由设于起落架上的拨杆驱动,舱门随着拨叉运动,实现收放,因此,采用这种结构的舱门收放装置无需为舱门设置专门的驱动装置,就能完成舱门的收放,减少了重量,提高无人机飞行效率,并且结构简单,减少舱门收放的无效动作,提高了无人机的空间利用率,具有良好的工艺性及经济性。
