Description

Technical Field

[0001] This application relates to the field of filing cabinet technology, specifically an RFID filing cabinet. Background Technology

[0002] With the development of information technology, records management is gradually shifting from traditional manual management to intelligent and automated management. RFID technology, due to its advantages such as non-contact identification and batch reading, is widely used in the field of records management.

[0003] Commonly available archival storage equipment includes ordinary filing cabinets and filing cabinets with basic RFID functionality. Ordinary filing cabinets rely entirely on manual management, which is inefficient and prone to errors. While filing cabinets with RFID functionality improve management efficiency to some extent, their unreasonable structural design makes RFID tags susceptible to interference from the metal cabinet, leading to reading failures or limited reading distances. To address these issues, an RFID filing cabinet has been proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an RFID filing cabinet that solves the problems of metal interference and wiring hazards through structural optimization.

[0005] To achieve the above objectives, this application provides the following technical solution: an RFID file cabinet, comprising a cabinet body and an anti-shielding component, wherein the anti-shielding component includes a non-metallic shielding layer fixedly connected to the inner wall of the cabinet body, multiple corrugated inner plates fixedly connected to both sides of the inner wall of the non-metallic shielding layer, two mounting brackets fixedly connected to both sides of the inner wall of the non-metallic shielding layer, multiple evenly distributed upper partitions installed between the four mounting brackets by bolts, two U-shaped connectors installed on the bottom surface of each upper partition by bolts, a lower partition installed at the bottom of each upper partition by two U-shaped connectors, a reserved opening on the outer surface of each lower partition, and an RFID antenna array fixedly connected to the inner wall of each reserved opening.

[0006] The above solution uses ABS composite material to cover the metal frame of the cabinet, effectively isolating the metal from electromagnetic interference with RFID signals. The corrugated inner panel breaks the planar reflection path and reduces signal attenuation through an asymmetrical structural design. The mounting bracket is fixed to the upper and lower partitions by U-shaped connectors to form a modular assembly structure, which is convenient for disassembly and maintenance. The RFID antenna array is embedded in the reserved opening of the lower partition and connected to the controller through the lead hole to achieve full coverage reading of RFID tags above and below.

[0007] Furthermore, the front of the cabinet is equipped with a hinged door, and the inside of the hinged door is equipped with a combination lock.

[0008] The above solution links the cabinet door with the combination lock, supporting various unlocking methods and ensuring the security of file storage and retrieval.

[0009] Furthermore, an indicator light and a voice prompt module are installed on the top of the cabinet, both of which are electrically connected to the combination lock.

[0010] Through the above solution, the indicator lights and voice prompt modules provide real-time feedback on the operation status, such as "the door is not closed tightly" or "the tag was read successfully," thereby improving the human-computer interaction experience.

[0011] Furthermore, an external power port is installed on the back of the cabinet.

[0012] The above solution allows external municipal power to be introduced into the cabinet via an external power port, facilitating the normal operation of the electrical components inside the cabinet.

[0013] Furthermore, an electrical socket is installed on the upper surface of the uppermost upper partition among the plurality of upper partitions, and the external power supply port is electrically connected to the electrical socket via a wire.

[0014] With the above solution, the external power port is connected to the electrical outlet via a concealed wire to power the RFID antenna array on the upper partition, ensuring stable voltage and eliminating exposed wiring.

[0015] Furthermore, the top of the cabinet is equipped with a removable top cover.

[0016] The above solution allows for easy detachable top cover design, facilitating future circuit maintenance.

[0017] Furthermore, each of the U-shaped connectors has multiple lead wire holes on its inner wall, and there is a certain gap between the upper and lower partitions.

[0018] The above solution allows for the reservation of gaps between the upper and lower partitions, which ensures air circulation, prevents dust accumulation, and reduces signal reflection interference between layers. The opening of lead holes enables a concealed wiring design, eliminating the safety hazards of exposed wiring.

[0019] Furthermore, the multiple corrugated inner plates are respectively located between the multiple upper partitions.

[0020] The above scheme defines the positional relationship between the corrugated inner plate and the upper partition, which can disrupt the electromagnetic wave reflection paths of different layers of upper partitions, reduce the signal attenuation rate, and optimize the actual shielding effect.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This RFID filing cabinet features a non-metallic shielding layer covering the inner wall of the cabinet, combined with an asymmetrical structure design of a corrugated inner panel. This effectively isolates the metal frame from electromagnetic interference with RFID signals, reducing signal attenuation. The modular mounting bracket and upper and lower shelves are quickly assembled via U-shaped connectors, supporting independent replacement of individual shelves and shortening maintenance time. The RFID antenna array is embedded in the reserved opening of the lower shelf, with concealed wiring through lead holes, achieving full coverage reading of tags above and below, improving identification distance and optimizing recognition rate. The concealed power supply design of the external power port and power strip eliminates the risk of exposed wiring. The detachable top cover simplifies circuit maintenance. The gap between the upper and lower shelves optimizes air circulation and reduces inter-layer reflection interference. The combination of a combination lock and voice prompt module enhances security and human-computer interaction efficiency, making it suitable for high-density file management scenarios.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1 , Figure 3 and Figure 4 This embodiment of an RFID filing cabinet includes a cabinet body 1 and an anti-shielding component 6. The anti-shielding component 6 includes a non-metallic shielding layer 601 fixedly connected to the inner wall of the cabinet body 1. The non-metallic shielding layer 601 is made of ABS composite material and fully covers the surface of the metal frame of the inner wall of the cabinet body 1 to form an electromagnetic isolation barrier. Multiple corrugated inner plates 602 are fixedly connected to both sides of the non-metallic shielding layer 601 in a symmetrically spaced manner. Each corrugated inner plate 602 has an asymmetrical curved surface structure design with gradient distribution of its peaks and troughs, which can effectively break the planar reflection path of electromagnetic waves. Two mounting brackets 603 are fixedly connected to both sides of the layer 601. The four mounting brackets 603 are symmetrically distributed. Their horizontal sections are detachably connected to the edge of the upper partition 604 by bolts to form a multi-layer horizontal support structure. Multiple upper partitions 604 are installed between the four mounting brackets 603 at even intervals by bolts to form the layered storage structure of the filing cabinet. Two U-shaped connectors 605 are fixedly installed on the bottom surface of each upper partition 604 by countersunk bolts. A lower partition 606 is installed on the bottom of each upper partition 604 by two U-shaped connectors 605, forming a modular assembly structure of upper and lower shelves.

[0026] Please see Figure 4 , Figure 5 and Figure 6 Each lower partition 606 has a pre-drilled opening 607 on its outer surface. An RFID antenna array 608 is fixedly connected to the inner wall of each pre-drilled opening 607. The pre-drilled opening 607 and the RFID antenna array 608 are connected by epoxy resin adhesive. Each U-shaped connector 605 has multiple lead-wire holes 609 on its inner wall. The inner wall of the lead-wire holes 609 is embedded with a silicone protective ring to ensure that the cables are not worn during frequent movement. There is a certain gap between the upper partition 604 and the lower partition 606. A gap is reserved between plate 604 and lower partition 606 to ensure air circulation and prevent dust accumulation, while also reducing signal reflection interference between layers. The lead hole 609 enables a concealed wiring design, eliminating the safety hazards of exposed wiring. Multiple corrugated inner plates 602 are located between multiple upper partitions 604, defining the positional relationship between the corrugated inner plates 602 and the upper partitions 604. This can disrupt the electromagnetic wave reflection paths of different upper partitions 604, reduce signal attenuation, and optimize the actual shielding effect.

[0027] It should be noted that a transverse pre-reserved gap is formed between the upper partition 604 and the lower partition 606 through a U-shaped connector 605, ensuring that the air between the layers can form a convection channel along the edge of the partition. This effectively prevents dust accumulation and reduces the specular reflection of electromagnetic waves between layers by utilizing the low dielectric constant of air. The concealed wiring design integrates the antenna array cable into the U-shaped connector 605 through the lead hole 609, with only the bolt connection point visible externally, completely eliminating the risk of pulling, wear, and short circuits of exposed wiring.

[0028] Please see Figure 1 , Figure 2 and Figure 3 The cabinet 1 has a hinged door 2 installed on the front, and a combination lock 3 is installed inside the door 2. The door 2 and the combination lock 3 are linked, supporting multiple unlocking methods to ensure the security of file storage and retrieval. The top of the cabinet 1 is equipped with an indicator light 4 and a voice prompt module 5. Both the indicator light 4 and the voice prompt module 5 are electrically connected to the combination lock 3. The indicator light 4 and the voice prompt module 5 provide real-time feedback on the operation status. The indicator light 4 displays statuses such as "door not closed tightly", "system abnormality", and "operation successful" through a combination of red, yellow, and green lights. The voice prompt module 5 broadcasts voice prompts such as "please close the door again" and "tag read successfully" through a high-fidelity speaker in real time, forming a dual sound and light feedback system, which significantly improves the intuitiveness of human-computer interaction and operational efficiency.

[0029] Please see Figure 2 , Figure 3 and Figure 4 An external power port 7 is installed on the back of the cabinet 1. Through the external power port 7, external municipal power can be introduced into the interior of the cabinet 1, thereby facilitating the normal operation of the electrical components inside the cabinet 1. Among the multiple upper partitions 604, the uppermost upper partition 604 is equipped with an electrical socket 8. The external power port 7 is electrically connected to the electrical socket 8 through a wire. The external power port 7 is connected to the electrical socket 8 through a concealed wire to power the RFID antenna array 608 on the upper partition 604. The voltage is stable and there are no exposed wires. The top of the cabinet 1 is equipped with a detachable top cover 9. The detachable design of the top cover 9 facilitates the later circuit maintenance.

[0030] In this embodiment, the inner wall of the cabinet 1 is covered by a non-metallic shielding layer 601, which, combined with the asymmetrical structural design of the wave-shaped inner panel 602, effectively isolates the electromagnetic interference of the metal frame to the RFID signal and reduces the signal attenuation rate. The modular mounting bracket 603 is quickly assembled with the upper partition 604 and the lower partition 606 through U-shaped connectors 605, supporting independent replacement of single-layer partitions and shortening maintenance time. The reserved opening 607 of the lower partition 606 embeds the RFID antenna array 608, and the wiring is hidden through the lead hole 609 to achieve full coverage reading of the upper and lower tags, improve the identification distance, and optimize the identification rate. The hidden power supply design of the external power port 7 and the power strip 8 eliminates the hidden wiring hazards. The detachable structure of the top cover 9 simplifies circuit maintenance. The reserved gap between the upper partition 604 and the lower partition 606 optimizes air circulation and reduces inter-layer reflection interference. The combination lock 3 and the voice prompt module 5 work together to improve security and human-computer interaction efficiency, making it suitable for high-density file management scenarios.

[0031] The working principle of the above embodiment is as follows: When the RFID filing cabinet is in operation, the problem of metal interference is first solved by the anti-shielding component 6 on the inner wall of the cabinet 1. The non-metallic shielding layer 601 is made of ABS composite material and covers the metal frame of the cabinet 1, effectively isolating the metal from the RFID. To mitigate electromagnetic interference, the corrugated inner plate 602, with its asymmetrical structure, breaks the planar reflection path, reducing signal attenuation. Distributed between the upper partitions 604, it separately disrupts the electromagnetic wave reflection paths of different partition layers, further reducing signal attenuation. The mounting bracket 603, upper partitions 604, and lower partitions 606 form a modular assembly structure via U-shaped connectors 605, facilitating disassembly and maintenance. Simultaneously, the lead-in holes 609 on the inner wall of the U-shaped connectors 605 enable concealed wiring, eliminating safety hazards from exposed wiring. Furthermore, the gap between the upper partitions 604 and lower partitions 606 ensures airflow to prevent dust accumulation and reduces inter-layer signal reflection interference. The RFID antenna array 608, fixedly connected to the inner wall of the reserved opening 607 on the outer surface of the lower partition 606, connects to the controller via lead-in holes 609, enabling monitoring of the RFID antennas above and below. Full-coverage tag reading improves recognition distance and accuracy. The cabinet door 2 on the front of cabinet 1 is linked with the internal combination lock 3, supporting multiple unlocking methods to ensure the security of file storage and retrieval. The indicator light 4 and voice prompt module 5 on the top are electrically connected to the combination lock 3, providing real-time feedback on operation statuses such as "door not closed tightly" and "tag read successfully," enhancing the human-computer interaction experience. The external power port 7 on the back of cabinet 1 introduces external municipal power and connects to the electrical socket 8 on the upper surface of the top shelf 604 via a hidden wire, providing stable power to internal electrical components such as the RFID antenna array 608. The removable top cover 9 facilitates future circuit maintenance. The overall structural design optimizes signal transmission, power supply system, and human-computer interaction, making it suitable for high-density file management scenarios.
