Intelligent Rotary Variable Volume Compartment

In response to the current situation where express parcels are piled up chaotically, resulting in low distribution efficiency and lack of safety guarantees during delivery, a smart rotatable and adjustable-volume box for express carts has been designed to achieve safe transport and civilized distribution during the express delivery process. This device uses a uniquely designed hexagonal prism box to ensure safe transport during the express delivery process; it achieves civilized distribution of parcels through a simple rotational motion; it uses a lead screw structure to achieve adjustable heights between layers; it incorporates removable vertical partitions to accommodate different sizes and types of parcels; and it applies a microcontroller to implement an intelligent 'parcel-finding-person' storage and retrieval mode.
