Description

Technical Field

[0001] This utility model relates to the field of item management technology, and in particular to a handheld RFID reader / writer device for an item box and an item management system. Background Technology

[0002] In the field of inventory management technology, the precise and efficient control of items within various inventory boxes plays a crucial role in improving operational efficiency and ensuring the smooth flow of materials. Whether in large-scale logistics warehousing scenarios (such as turnover boxes) where the rapid inventory and tracking of massive quantities of goods is required, or in daily life where individuals need convenient storage boxes (such as suitcases), increasingly higher demands are being placed on inventory management technology.

[0003] With the continuous development of technology, RFID technology has been introduced into the field of goods management. RFID technology, or Radio Frequency Identification, is an advanced method of data processing that uses wireless radio frequency for non-contact, two-way data communication. It can scan and identify electronic tags, QR codes, barcodes, and other data, enabling the identification and exchange of information. Compared to traditional goods identification methods, RFID technology has significant advantages such as no need for visual contact, fast identification speed, and the ability to identify multiple tags simultaneously, greatly improving the efficiency and accuracy of goods management.

[0004] Existing handheld RFID readers for item boxes mostly adopt an integrated reader / writer terminal design. However, this design has many drawbacks: the equipment cost is high, as the integrated terminal combines multiple functional modules such as reading, writing, and processing, increasing production and maintenance costs. At the same time, the equipment lacks flexibility; when the reading or processing module malfunctions, it often requires complete repair or replacement, which is time-consuming, labor-intensive, and costly. Utility Model Content

[0005] The main purpose of this invention is to propose a handheld RFID reader / writer device and a goods management system for goods boxes, aiming to solve the technical problems of high cost and poor flexibility of existing handheld RFID reader / writer devices for goods boxes.

[0006] To achieve the above objectives, this utility model proposes a handheld RFID reader / writer for a box, comprising:

[0007] The housing has an inner cavity, a hand grip is provided on one side of the housing, and a fixing component for fixing the mobile communication terminal is provided on the other side of the housing.

[0008] The RFID reading module includes an RFID motherboard disposed in the inner cavity and an antenna disposed at the end of the housing. The RFID motherboard is electrically connected to the antenna to read information of the RFID electronic tag through the antenna. The mobile communication terminal is communicatively connected to the RFID motherboard and is used to receive, display and process the information of the RFID electronic tag read by the RFID motherboard.

[0009] In some embodiments, the fixing component includes a support platform protruding from the housing and a first clamping arm and a second clamping arm movably connected to the support platform, wherein the first clamping arm, the second clamping arm and the support platform form an accommodating space for clamping the mobile communication terminal.

[0010] In some embodiments, the end of the housing is provided with an antenna mounting bracket for mounting the antenna.

[0011] In some embodiments, the housing is cylindrical, the antenna mount is disc-shaped, and the diameter of the antenna mount is larger than the diameter of the housing.

[0012] In some embodiments, the housing has a wire passage hole at one end facing away from the antenna mounting base;

[0013] The mobile communication terminal is connected to the RFID motherboard via a data cable passing through the cable hole.

[0014] In some embodiments, the RFID reading module further includes a control switch electrically connected to the RFID motherboard, the control switch being at least partially exposed outside the grip area.

[0015] This utility model also provides an item management system, including:

[0016] A storage box, having a cavity for storing items;

[0017] A handheld RFID reader / writer is used to read, display, and process information from RFID electronic tags, which are used to detachably connect to items stored in the item box.

[0018] In some embodiments, the item box has an opening that communicates with the receiving cavity, and the handheld RFID reader reads information from the RFID electronic tag located inside the item box through the opening.

[0019] In some embodiments, a protective cap is also included for covering the opening; and / or,

[0020] The opening includes a first hole segment and a second hole segment. The diameter of the first hole segment is larger than the diameter of the second hole segment, and a stepped surface is formed at the connection between the diameter of the first hole segment and the second hole segment. The handheld RFID reader / writer is at least partially located in the first hole segment, and the stepped surface provides support for the handheld RFID reader / writer.

[0021] In some embodiments, the inner wall of the item box is provided with a metal shielding layer.

[0022] The handheld RFID reader / writer provided in this application is used in item boxes. By integrating the RFID reading module into the housing, and utilizing an existing mobile communication terminal for data processing, storage, and display functions, it avoids the high production and maintenance costs associated with integrated terminals that combine multiple functions. Users only need to purchase a relatively low-cost handheld RFID reader / writer and combine it with their existing mobile communication terminal to achieve complete reader / writer functionality, significantly reducing the investment cost. When the RFID reading module (such as the RFID motherboard or antenna) malfunctions, only the faulty part needs to be repaired or replaced, unlike traditional integrated devices where the entire terminal needs repair or replacement. This modular design makes device repair and replacement more convenient, greatly improving the overall flexibility of the device, reducing downtime caused by device failures, and increasing work efficiency.

[0035] Please refer to Figures 1 to 3 One embodiment of this application proposes a handheld RFID reader / writer device 100 for a box 310, including a housing 10 and an RFID reading module 20. The housing 10 has an inner cavity, a hand grip 11 is provided on one side of the housing 10, and a fixing component 12 for fixing a mobile communication terminal 200 is provided on the other side of the housing 10.

[0036] The RFID reading module 20 includes an RFID motherboard 21 located in the inner cavity and an antenna 22 located at the end of the housing 10. The RFID motherboard 21 is electrically connected to the antenna 22 to read information from the RFID electronic tag 320 through the antenna 22. The mobile communication terminal 200 is communicatively connected to the RFID motherboard 21 to receive, display and process the information from the RFID electronic tag 320 read by the RFID motherboard 21.

[0037] The RFID motherboard 21 is electrically connected to the antenna 22. Based on the principles of RFID technology, the antenna 22 emits radio frequency signals at a specific frequency. When a box 310 carrying an RFID tag 320 enters the signal coverage area of ​​the antenna 22, the coil inside the RFID tag 320 senses the radio frequency signal and generates an induced current, thus activating it. The activated RFID tag 320 then transmits its stored information (such as the item's identification and attribute information) in the form of a radio frequency signal. After receiving these returned radio frequency signals, the antenna 22 transmits them to the RFID motherboard 21, which decodes and processes the signals to extract the relevant information from the RFID tag 320.

[0038] The mobile communication terminal 200 is fixed to the housing 10 by the fixing component 12 and establishes a communication connection with the RFID motherboard 21 (such as wireless communication methods like Bluetooth or Wi-Fi, or wired communication methods). The RFID motherboard 21 sends the processed RFID electronic tag 320 information to the mobile communication terminal 200. The mobile communication terminal performs further analysis, storage, and other processing operations on the received information, and simultaneously displays the information intuitively to the user through its display screen, completing the entire process of information reading, transmission, processing, and presentation.

[0039] The grip 11 on one side of the housing 10 is ergonomically designed. When the user holds the device, the grip 11 provides a comfortable and stable grip, reduces hand fatigue, and facilitates the user's long-term operation of the device to read RFID electronic tag 320 information in various scenarios.

[0040] It should be noted that the item box 310 described in this application embodiment can be a container such as a turnover box or suitcase used for storing items. For example, in logistics warehousing, turnover boxes are used for goods transportation and storage. Workers can use a handheld RFID reader / writer 100 to quickly obtain information such as the type and quantity of goods inside the box, enabling real-time inventory updates and efficient sorting. In daily life, suitcases are used for personal storage. Users can use this device to manage items inside the suitcase that are affixed with RFID electronic tags 320, quickly confirming the location of items when traveling and avoiding omissions.

[0041] The fixing component 12 of this application can be a spring clip structure, using the elastic force of the spring to clamp the mobile communication terminal 200; or it can be a magnetic structure, using the attractive force of a magnet to attract the mobile communication terminal 200 to the housing 10. Of course, this is only an example, and the embodiments of this application are not limited herein.

[0042] This embodiment integrates the RFID reading module 20 into the housing 10, while utilizing the existing mobile communication terminal 200 to handle data processing, storage, and display functions. This avoids the high production and maintenance costs associated with a single integrated terminal that combines multiple functions. Users only need to purchase a relatively low-cost handheld RFID reader / writer 100 and combine it with their existing mobile communication terminal 200 to achieve complete reader / writer functionality, significantly reducing device investment costs. When the RFID reading module 20 (such as the RFID motherboard 21 or antenna 22) malfunctions, only the faulty part needs to be repaired or replaced, unlike traditional integrated devices where the entire terminal needs repair or replacement. This modular design makes device repair and replacement more convenient, greatly improving the overall flexibility of the device, reducing downtime due to device malfunctions, and increasing work efficiency.

[0043] Please continue to refer to this. Figure 2 In some embodiments, the fixing component 12 includes a support platform 121 protruding from the housing 10 and a first clamping arm 122 and a second clamping arm 123 movably connected to the support platform 121. The first clamping arm 122, the second clamping arm 123 and the support platform 121 form an accommodating space for clamping the mobile communication terminal 200.

[0044] The supporting platform 121 provides basic support for the entire fixed component 12. It protrudes from the housing 10, ensuring the stability and relative height of the installation position of the mobile communication terminal 200, and facilitating its cooperation with the RFID reading module 20.

[0045] The first clamping arm 122 and the second clamping arm 123 are movably connected to the support platform 121 and can open and close around the connection point. When it is necessary to clamp the mobile communication terminal 200, the user manually moves the first clamping arm 122 and the second clamping arm 123 to open them outward, expanding the accommodating space. Then, the mobile communication terminal 200 is placed on the support platform 121, and the first clamping arm 122 and the second clamping arm 123 are released. Under their own weight or the action of built-in elastic elements (such as torsion springs), they move towards the center until they are in close contact with both sides of the mobile communication terminal 200, thus stably clamping the terminal within the accommodating space. This movably connected design can flexibly adapt to mobile communication terminals 200 of different sizes and meet diverse usage needs.

[0046] In this embodiment, since the first clamping arm 122 and the second clamping arm 123 are movable, they can adapt to mobile communication terminals 200 of different sizes. Whether it is a small smartphone or a larger tablet computer, stable clamping can be achieved by adjusting the position of the clamping arms, which greatly improves the applicability of the handheld RFID reader / writer 100 and reduces the trouble of having to replace different clamping devices due to differences in terminal device size.

[0047] In some embodiments, the end of the housing 10 is provided with an antenna mounting base 13 for mounting the antenna 22.

[0048] The antenna mounting base 13 is located at the end of the housing 10, providing a stable mechanical support structure for the antenna 22. The antenna 22 is securely installed on the mounting base through specific connection methods (such as screw fixing, snap connection, glue bonding, etc.), preventing the antenna 22 from shaking, shifting or even falling off during daily use of the device, and ensuring that the antenna 22 can be kept in the optimal working position for stable transmission and reception of radio frequency signals.

[0049] In this embodiment, mounting the antenna 22 on the antenna mounting base 13 at the end of the housing 10 makes the structure of the entire handheld RFID reader / writer 100 more compact and reasonable. The antenna 22 can interact with the outside world in the optimal posture and position, while avoiding mutual interference between the antenna 22 and other internal components of the device, thus improving the overall performance and stability of the device.

[0050] In some embodiments, the housing 10 is cylindrical, the antenna mounting base 13 is disc-shaped, and the diameter of the antenna mounting base 13 is larger than the diameter of the housing 10.

[0051] In this embodiment, the antenna mounting base 13 is designed in a disc shape with a diameter larger than that of the housing 10. On the one hand, the disc-shaped structure provides a larger mounting surface for the antenna 22, making the installation of the antenna 22 more stable and secure, and better fixing the position of the antenna 22 to prevent it from shaking or shifting during use. On the other hand, the larger diameter antenna mounting base 13 protrudes from the cylindrical housing 10, allowing the antenna 22 to have better spatial contact with the surrounding environment after installation. This facilitates the antenna 22's omnidirectional transmission and reception of radio frequency signals, avoiding signal transmission being affected by the obstruction of the housing 10, ensuring the quality and stability of the signal during transmission, thereby improving the accuracy and reliability of reading information from the RFID electronic tag 320.

[0052] It should be understood that the housing 10 can be a cylindrical structure, or it can be a square column or other polygonal structure, and this application embodiment does not limit it. Similarly, the antenna mounting base 13 can also be a square structure or other polygonal structure.

[0053] In some embodiments, the housing 10 has a wire hole 14 at one end facing away from the antenna mounting base 13;

[0054] The mobile communication terminal 200 is connected to the RFID motherboard 21 via a data cable 201 passing through the cable hole 14.

[0055] A cable pass-through hole 14 is provided at one end of the housing 10 facing away from the antenna mounting base 13, providing a channel for the data cable 201 to pass through the housing 10. The mobile communication terminal 200 and the RFID motherboard 21 are connected via the data cable 201. When connecting the two, one end of the data cable 201 is inserted into the corresponding interface of the mobile communication terminal 200, and the other end passes through the cable pass-through hole 14 into the housing 10, where it mates with the interface on the RFID motherboard 21, thus achieving a physical connection between the two. This connection method ensures a reasonable layout of the data cable 201 within the device, preventing the data cable 201 from being arbitrarily tangled or damaged externally.

[0056] In some embodiments, the RFID reading module 20 further includes a control switch 23 electrically connected to the RFID motherboard 21, and the control switch 23 is at least partially exposed outside the grip portion 11.

[0057] The control switch 23 is electrically connected to the RFID motherboard 21. The operation of the RFID reading module 20 is controlled by closing and opening the control switch 23. When the switch is closed, the circuit is turned on, the RFID reading module 20 is powered on and can perform operations such as reading RFID tags; when the switch is opened, the circuit is turned off, the module stops working, thus realizing flexible control of the RFID reading module 20.

[0058] In this embodiment, the control switch 23 is at least partially exposed outside the grip portion 11. This allows the user to easily touch and operate the control switch 23 while holding the device, enabling convenient control of the device. When holding the device, the user can easily touch the control switch 23 exposed outside the grip portion 11 with their fingers, quickly turning the RFID reading function on or off without having to search for or open other parts of the device. This is particularly convenient in scenarios requiring frequent use or pausing of the reading function, such as during warehouse inventory checks, where staff can turn the reading module on or off as needed, improving work efficiency.

[0059] Furthermore, the control switch 23, located outside the grip area 11, is ergonomically designed, allowing the user's fingers to naturally rest on the switch when holding the device, making operation comfortable and convenient and reducing hand fatigue. This design optimizes the user's interaction with the device, making it easier to use.

[0060] Please refer to Figure 1 , Figure 3and Figure 4 This application embodiment also provides an item management system, including an item box 310 and a handheld RFID reader / writer 100. The item box 310 has a receiving cavity for storing items. The handheld RFID reader / writer 100 is used to read, display and process information from RFID electronic tags 320, which are detachably connected to the items stored in the item box 310.

[0061] The item box 310 has a cavity for storing various items, and an RFID electronic tag 320 is detachably connected to the items stored in the item box 310. In this way, each item corresponds to a unique RFID electronic tag 320, establishing a correspondence between the item and the electronic tag, so that each item has an identifiable identity.

[0062] The RFID reading module 20 of the handheld RFID reader / writer 100 (including the RFID motherboard 21 and antenna 22, etc.) transmits radio frequency signals of a specific frequency through the antenna 22. When the device approaches the RFID electronic tag 320 inside the item box 310, the coil inside the tag senses the radio frequency signal and generates an induced current, thus activating it. The activated tag returns its stored information (such as the name, specifications, quantity, batch, etc. of the item) in the form of radio frequency signals. After receiving these returned signals, the antenna 22 transmits them to the RFID motherboard 21 for decoding and processing.

[0063] The RFID motherboard 21 transmits the processed information to the mobile communication terminal 200 via a communication connection (such as a data cable 201 connection or a wireless communication connection). The mobile communication terminal 200 uses its powerful processing capabilities to further analyze, store, and process the information, and displays the information intuitively to the user through its display screen, allowing the user to clearly understand the relevant information of the items in the item box 310.

[0064] Since the item management system of this embodiment adopts all the technical solutions of all the embodiments of the handheld RFID reader / writer 100 described above, the item management system of this utility model also has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0065] In some embodiments, the item box 310 has an opening 330 that communicates with the receiving cavity, and the handheld RFID reader / writer 100 reads the information of the RFID electronic tag 320 located in the item box 310 through the opening 330.

[0066] The antenna 22 of the RFID reader / writer emits radio frequency signals at a specific frequency, which propagate in the form of electromagnetic waves. When the item box 310 has an opening 330 connecting to the receiving cavity, the radio frequency signal can enter the item box 310 through the opening 330 and reach the RFID electronic tag 320 placed inside the box. After receiving the radio frequency signal, the RFID electronic tag 320 uses the energy obtained from the induced current to send out its own encoded information. This information is then transmitted out of the item box 310 in the form of a radio frequency signal through the opening 330, received by the antenna 22 of the RFID reader / writer, and then transmitted to the RFID motherboard 21 for decoding and processing, ultimately realizing the reading of the information of the RFID electronic tag 320 inside the item box 310.

[0067] In this embodiment, the presence of the opening 330 breaks the completely sealed state of the item box 310, providing a physical channel for the signal of the RFID reader / writer. This allows for effective signal interaction between the device and the tag, enabling the information of the internal RFID electronic tag 320 to be read through the opening 330 without opening the item box 310. In some cases, such as when the item box 310 contains a large number of heavy items or when the items need to be kept sealed (e.g., in environments with hygiene and safety requirements), this method greatly improves the convenience of reading information. For example, in a pharmaceutical warehouse, the item box 310 storing medicines may need to be kept sealed to ensure the quality of the medicines. Reading the tag information through the opening 330 allows for the acquisition of relevant medicine information without breaking the seal.

[0068] For scenarios involving the management of a large number of boxes 310, such as inventory and tracking of goods in a logistics warehouse, it is not necessary to open each box individually. Information can be read directly through the opening 330, which can significantly improve work efficiency and save time and labor costs. Staff can quickly scan multiple boxes 310 to monitor the status of the items inside in real time.

[0069] Please refer to Figure 4 and Figure 5 In some embodiments, the item management system further includes a protective cover 340 for closing the opening 330; and / or,

[0070] The opening 330 includes a first hole segment 331 and a second hole segment 332. The diameter of the first hole segment 331 is larger than the diameter of the second hole segment 332, and a stepped surface 333 is formed at the connection between the diameter of the first hole segment 331 and the second hole segment 332. The handheld RFID reader / writer 100 is at least partially located in the first hole segment 331, and the stepped surface 333 provides support for the handheld RFID reader / writer 100.

[0071] The main function of the protective cover 340 is to close the opening 330 when it is not necessary to read information from the RFID tag 320. The protective cover 340 is connected to the container 310 via a specific connection method (such as hinge or snap-fit). When closed, it tightly seals the opening 330, preventing dust, foreign objects, and moisture from entering the container 310's cavity. It also reduces external electromagnetic interference affecting signal transmission between the RFID tag 320 and the reader / writer inside the container. When information needs to be read, the protective cover 340 is opened, exposing the opening 330 so that the RFID reader / writer can smoothly interact with the tag inside the container through the opening 330.

[0072] When the RFID reader approaches the opening 330 to read information, at least a portion of it (the detection end) can extend into the first aperture 331. Because the first aperture 331 has a relatively large diameter, it provides sufficient space for the reader to enter the opening 330, while the stepped surface 333 provides support for the reader, ensuring a relatively stable position during information reading. This facilitates better alignment between the antenna 22 and the RFID tag 320 inside the box, thereby improving signal transmission efficiency and reading accuracy.

[0073] In some embodiments, the inner wall of the item box 310 is provided with a metal shielding layer.

[0074] In this embodiment, the metal shielding layer effectively blocks external electromagnetic signals from entering the contents of the container 310, preventing interference from the complex external electromagnetic environment on the signal transmission between the RFID tag 320 and the reader / writer inside the container, thus ensuring the accuracy and stability of the read information. Simultaneously, it also prevents signals emitted by the RFID tag 320 inside the container from leaking to the outside, improving the system's security and confidentiality.

[0075] In addition, the metal shielding layer can confine the radio frequency signal emitted by the RFID reader to the inside of the item box 310, reduce the scattering and attenuation of the signal to the outside space, and make the signal more concentrated inside the box to interact with the RFID electronic tag 320. This enhances the signal strength between the reader and the electronic tag, improves the efficiency and quality of signal transmission, and helps to read the electronic tag information more quickly and accurately.

[0076] The above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
