The guide rails 82 include two rails, which are respectively installed on the inner surface of the left side plate 2 and the inner surface of the right side plate 3 of the box body 1 at corresponding positions. That is, the two rails 82 are installed on different side plates, respectively, but their installation positions are equally spaced from the opening 9, and their installation heights are equally spaced from the bottom plate 5, so that the tray 81 can be smoothly moved on the rails 82. In this embodiment, the mobile placement module 8 is actually a drawer structure, and the drawer of the drawer is the tray 81, on one hand, this arrangement can save the time for the articles to enter and exit the opening 9, so that the articles are concentrated in the placement space, and the RFID reader can conveniently count the articles; on the other hand, if the articles leak, the leaked liquid can be concentrated in the tray 81, so that the influence on other storage spaces or other boxes in the intelligent storage cabinet is avoided.

The utility model discloses still relate to an intelligent locker, as shown in fig. 2, this kind of intelligent locker includes that the cabinet body 10 is in with the setting a plurality of boxes 1 in the cabinet body 10, every box 1 form an independent storing space, and every box 1 is provided with seals or lets out the chamber door 20 of this box, box 1 is the aforesaid the box with electromagnetic signal shielding function. In the present embodiment, if the case 1 is a single case, although no signal is leaked from the side panel connection of the case 1, the signal can be transmitted to the outside through the opening 9. However, in the above intelligent storage cabinet, due to the arrangement of the door 20, the door 20 can seal the opening 9 when closed, so in this embodiment, when the door 20 is closed, the box 1 is sealed to form a separate signal environment isolated from the outside, which makes the electromagnetic signal of the high frequency RFID reader/writer arranged in the box 1 limited inside the box 1 and not transmitted to the outside when the high frequency RFID reader/writer checks the articles in the box 1, and therefore the phenomena of serial reading and missing reading of the high frequency RFID reader/writer are not easy to occur.

In the present embodiment, as shown in fig. 3, in order to further improve the electromagnetic shielding effect of the door 20, the door 10 includes a door flap 22 that is turned toward the inside of the door 20; conductive foam 21 which is mutually connected and matched with the shape of the protruding part 71 is further arranged in the position enclosed by the box door folding edge 22, and the conductive foam 21 is contacted with the protruding part 71 of the box body 1 when the box door 20 is closed, so that the shielding of electromagnetic signals is realized. Specifically, in the present embodiment, the conductive foam 21 is interconnected to form a square structure having a shape corresponding to the shape of the opening 9, and the conductive foam 21 is adhered to the inner surface of the panel of the door 20 by the edge of the door flange 22. That is, the conductive foam 21 is placed in a shape like a Chinese character 'kou' on the door 20, and each side is communicated with the adjacent side; meanwhile, each side of the square is closely attached to the edge of the box door folding edge 22; each side of the conductive foam 21 has a set width and thickness such that each side of the protruding portion 71 of the case 1 can contact its corresponding conductive foam 21.

In order to correspond to the arrangement of the conductive foam 21, a copper foil layer (not shown) is further arranged at a position where the protruding portion 71 contacts the conductive foam 21, and the copper foil layer is adhered or welded on the protruding portion 71. With this arrangement, the contact resistance between the conductive foam 21 and the protruding portion 71 is improved, so that the shielding effect at the position of the door 20 (i.e., the shielding effect at the position of the opening 9) is enhanced.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
