Storage device

A storage device, comprising:

• a storage cabin, having a receiving portion and an opening portion, the storage cabin comprising a top plate and a bottom plate, the receiving portion and the opening portion are located between the top plate and the bottom plate;
• a carrier assembly, located in the receiving portion and comprising a plurality of carrier plates, the plurality of carrier plates comprising a first carrier plate, a second carrier plate, and a third carrier plate, the first carrier plate is adjacent to the bottom plate, the third carrier plate is adjacent to the top plate, and the second carrier plate is located between the first carrier plate and the third carrier plate;
• a transmission assembly, connected to the carrier assembly and selectively moving the carrier plates;
• a door assembly, comprising a first door panel, a second door panel, and an actuator, wherein the first door panel and the second door panel are adjacent to the opening portion, and the actuator is configured to actuate the first door panel and the second door panel;
• and
• a controller set, configured to drive the transmission assembly to make the first carrier plate and the second carrier plate divide the receiving portion and the opening portion into a first storage space and a first access opening respectively according to an item height, and drive the door assembly the actuator to make the first door plate and the second door plate cover a portion of the opening portion other than the first access opening, wherein a height of the first storage space corresponds to the item height;
• and
• wherein the storage space is subtracted from the receiving portion to obtain a remaining space, and in response to another item height is larger than a height of the remaining space, the controller set is configured not to drive the transmission assembly to form a second storage space through division by the second carrier plate and the third carrier plate;
• wherein the access opening has an identification code, and the controller set drives, according to the identification code, the door assembly to cover the portion of the opening portion other than the first access opening corresponding to the identification code.
