The invention relates to a foldable compartment. The foldable compartment comprises side frames and baseplates. The compartment is divided into two parts including a front part and a rear part. The baseplates of the front and rear parts are hinged, and the junction of the side frames of the front and rear parts is of a movable meshing structure. An automatic-unloading trunk capable of preventing material unloading and lateral overturning using the foldable compartment comprises a trunk frame, the compartment and a lifting mechanism. One end of the compartment is hinged to one end of the trunkframe, one end of the lifting mechanism is connected to the other end of the trunk frame, and the other end of the compartment is connected to the other end of the lifting structure. The centrally foldable compartment is used for replacing conventional compartments. When materials are unloaded, the front part of the compartment rises first, and then the rear part of the compartment rises. Since aninclination angle of the front part of the compartment reaches a critical inclination angle of material falling earlier than the rear part of the compartment, materials at the front part of the compartment slides down first, and materials at the rear part of the compartment are pushed to slide down together. In this way, the problem is avoided that the compartment is laterally overturned due to the fact that the gravity center of the compartment is higher since the materials at the rear part of the compartment slide down earlier than the materials at the front part of the compartment.
