[0002] China Authorization Publication No. CN220147896U, with an authorization publication date of December 8, 2023, discloses a packaging structure and packaging box for a sweeping robot device, as well as a packaging box for cleaning equipment. The packaging structure of the sweeping robot device includes a base, a middle pad, and an upper pad. The middle pad is located above the base and defines a first accommodating chamber with the middle pad and the base. The upper pad is located above the middle pad and defines a second accommodating chamber with the middle pad and the upper pad. The base station of the sweeping robot device and one of the sweeping robots are located in the first accommodating chamber, and the other of the base station and the sweeping robot is located in the second accommodating chamber, thereby facilitating the transportation or handling of the sweeping robot, the base station, and other supporting components.
