The cabin plate part surrounds the frame part to form a cargo cabin main body.

[0106] Among them, the recyclable unmanned helicopter cargo cabin includes two cabin door parts 6. The two cabin door parts 6 are longitudinally mirror-imaged and arranged at both ends of the cargo cabin main body, and can be opened in both directions, so that the material can be quickly and conveniently loaded and unloaded, and the cargo accessibility is good.

[0107] The frame part of the recyclable unmanned helicopter cargo cabin involved in the method of the embodiment includes a main frame assembly 1 and a bottom frame assembly 2; the main frame assembly 1 is connected to the bottom frame assembly 2; the cabin plate part includes a cargo cabin top panel assembly 3, a cargo cabin bottom plate assembly 4 and a cargo cabin side panel assembly 5; the cabin door part 6 is hingedly connected to the cargo cabin top panel assembly 3 at a first end, is buckled to the cargo cabin bottom plate assembly 4 at a second end and is buckled on the cargo cabin side panel assembly 5.
