Description

Technical Field

[0001] This utility model relates to the technical field of clothing, specifically a garment with an RFID tag. Background Technology

[0002] RFID technology, short for Radio Frequency Identification, is a type of automatic identification technology. It uses radio frequency for non-contact, two-way data communication, reading and writing data to a recording medium (electronic tag or RFID card) to achieve target identification and data exchange. By attaching RFID tags to clothing, individuals wearing the garment can be automatically identified when entering or leaving the premises. Therefore, it can be widely used in scenarios such as schools and factories for anti-counterfeiting and traceability of clothing, warehouse management, and access control for personnel entering and exiting controlled areas. Specifically, it involves an RFID reader identifying the corresponding RFID tag and providing information and controlling access permissions.

[0003] There are generally three methods for installing RFID tags on clothing in existing technologies: 1. A decorative hangtag is attached to the garment, and the RFID tag is placed inside the decorative hangtag; 2. Attach the complete RFID tag to the garment by sewing or pasting. 3. By printing the antenna on the clothing, and then combining the chip and the antenna, an RFID tag is formed.

[0004] It is easy to see that the RFID tags in the above three existing methods are all external or additionally attached to the clothing. Therefore, with long-term use and repeated washing of the clothing, the RFID tags are prone to falling off. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art: to provide a garment with an RFID tag, which can integrate the antenna of the RFID tag with the garment body in an integrated manner, so that the antenna and the garment body are firmly combined, thereby reducing the chance of the RFID tag falling off.

[0006] Therefore, one objective of this invention is to provide a garment with an RFID tag, comprising a garment body and an RFID tag. The RFID tag consists of at least an antenna and a chip. The antenna includes conductive fibers, which are integrally formed with the garment body. The chip is fixedly connected to the garment body and electrically connected to the antenna, and the chip is covered with a protective layer. The conductive fibers are integrated into the garment body as part of the garment fabric itself, preventing them from falling off during washing. Furthermore, the conductive fibers, based on their inherent conductivity, can function as an antenna. After embedding the chip, a complete RFID tag is formed. Compared to existing printed or pasted antennas, this method allows the RFID tag to be more securely attached to the garment body.

[0007] According to one example of this utility model, the garment body has a preset marking area, and conductive fibers are arranged in the marking area and integrally woven with the garment body to form an antenna. The conductive fibers and the non-conductive fibers of the garment body are integrally processed together by weaving to form the garment body. Therefore, the conductive fibers are firmly bonded to the garment body as part of the garment body and will not fall off due to long-term use and washing.

[0008] According to one example of this invention, conductive adhesive is provided between the chip and the antenna. The chip is adhered to and electrically connected to the antenna via the conductive adhesive. The chip is attached to the antenna with the conductive adhesive, allowing the chip and antenna to combine to form a complete RFID tag with a compact structure.

[0009] According to one example of the present invention, the protective layer passes through conductive fibers and extends to the side of the antenna away from the chip.

[0010] According to one example of the present invention, the chip is electrically connected to the antenna via a connecting wire.

[0011] According to one example of this invention, a portion of the conductive fiber in the antenna extends toward the chip location to form a connecting wire. This connecting wire passes through the protective layer and is electrically connected to the chip. By using a portion of the conductive fiber in the antenna itself as the connecting wire, after the connecting wire is electrically connected to the chip, the portion of the connecting wire outside the protective layer is integrated with the antenna, resulting in a more secure connection and reducing the risk of the connecting wire breaking.

[0012] According to one example of this invention, the protective layer is fixed to the garment body and is made of insulating material, and the chip is encapsulated inside the protective layer. The protective layer is fixed to the garment, and the chip is encapsulated within the protective layer and electrically connected to an antenna via additional connecting wires.

[0013] According to one example of the present invention, the protective layer is made of rubber.

[0014] According to one example of the present invention, the conductive fiber includes metal fiber, carbon fiber, or chemical fiber formed by spinning a polymer mixed with a conductive medium.

[0015] The above technical solution has the following advantages or beneficial effects: First, the conductive fiber, as part of the garment body, is combined with the original fabric of the garment body to form a complete garment body. At the same time, due to the conductive properties of the conductive fiber, the conductive fiber can be used as an antenna located in the identification area of ​​the garment body. After the chip is fixedly installed on the garment body, the chip is electrically connected to the conductive fiber to form a complete RFID tag. Second, the protective layer is used as a label on the garment body, and the chip is embedded in the label. The chip is electrically connected to the antenna through a connecting wire. The label serves both as an identifier and as a container and enclosure for the chip.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] The following describes in detail, with reference to the accompanying drawings, a garment with an RFID tag according to an embodiment of the present invention.

[0023] This utility model provides a garment with an RFID tag, as shown in the figure. It includes a garment body 1 and an RFID tag. The RFID tag consists of at least an antenna 2 and a chip 3. The antenna 2 includes conductive fibers, which are integrally formed with the garment body 1. The chip 3 is fixedly connected to the garment body 1 and electrically connected to the antenna 2. The chip 3 is covered with a protective layer 4.

[0024] The structure in the above embodiments refers to the conductive fibers being incorporated into the fabric of the garment body 1 as part of the garment body 1, rather than being glued or sewn onto the outer surface of the garment body 1.

[0025] Based on the preferred embodiment described above, see [reference]. Figure 1 As shown, the garment body 1 is a top. A marking area 1.1 is pre-defined on the front chest of the top. During the manufacturing of the garment body 1, some or all of the fabric within the marking area 1.1 is replaced with conductive fibers. These conductive fibers, along with the non-conductive fibers used in the garment body 1 itself, are woven together to form the garment body 1. The conductive properties of the conductive fibers allow them to function as an antenna. Specifically, the conductive fibers are arranged within the marking area 1.1 and integrally woven with the garment body 1 to form an antenna 2. The chip 3 is then fixed to the garment body 1 and electrically connected to the antenna 2 to form a complete RFID tag. In this embodiment, because the antenna 2 is integrally connected to the garment body 1, it will not detach from the garment body 1 due to use or washing. Furthermore, the chip 3 is small in size, making it less likely to fall off when fixed to or embedded in the garment body 1. Therefore, this method is more robust and reliable than the prior art where the antenna is printed on the outer wall of the garment body 1 or attached to the garment body 1.

[0026] Preferably, the length and width of the chip 3 are both less than 1 mm. Specifically, the length and width of the chip 3 are both 0.5 mm, and the preferred model of the chip 3 is M750, M730, or R6P. The chip 3 is a commercially available product. Due to its small size, the chip 3 is relatively securely fixed to the garment body 1 and glued in place by the protective layer 4. In the prior art, the detachment of RFID tags from garments mainly involves the antenna part. Since the antenna is a sheet-like structure with a large area, it is easy for it to detach or partially fall off due to bending or washing during garment use, causing the entire antenna to fail.

[0027] Based on one of the preferred examples of chip 3 in the above embodiments: See Figure 2As shown, conductive adhesive 5 is provided between the chip 3 and the antenna 2. When the chip 3 is attached to the antenna 2, an electrical connection is formed between them through the conductive adhesive 5. Due to the adhesiveness of the conductive adhesive 5 itself, the chip 3 can be firmly attached to the antenna 2. Specifically, the conductive fibers are woven to form the antenna 2. The existing conductive adhesive 5 is conventionally a liquid glue. Therefore, when the conductive adhesive is applied to the antenna 2, some of the conductive adhesive penetrates from the pores formed by the conductive fiber weave into the antenna 2 or penetrates to the other side of the antenna 2. This allows the conductive adhesive 5 to be firmly bonded to the antenna 2. Finally, the protective layer 4 further covers the portion of the antenna 2 where the chip 3 is located, including the conductive adhesive 5 and the part of the antenna 2 connected to the chip 3.

[0028] Preferably, the protective layer 4 can also cover all the antennas 2 within the protective layer 4.

[0029] In the above embodiment, since the antenna 2 is formed by integrally weaving conductive fibers with the garment body 1, the antenna 2 has a porous mesh fabric structure. The protective layer 4 is preferably a flexible waterproof layer, such as rubber. When the protective layer 4 is in a liquid state, it can be coated on the chip 3, and the protective layer 4 can penetrate into the antenna 2 based on its own liquid fluidity, even penetrating to the back of the antenna 2 away from the chip 3. After the protective layer 4 is cured, it can be firmly bonded to the antenna 2 and the garment body 1, further reducing the risk of the protective layer 4 falling off the garment body 1.

[0030] Furthermore, the aforementioned protective layer 4 is a protective layer made of rubber.

[0031] A second preferred example of chip 3 based on the above embodiments: See Figure 3 As shown, chip 3 is electrically connected to antenna 2 via connecting wire 6. Further, the connecting wire 6 is a portion of the conductive fibers in antenna 2; that is, a portion of the conductive fibers in antenna 2 is pulled out and extended towards the location of chip 3 to serve as the connecting wire 6. The front end of the connecting wire 6, away from antenna 2, passes through the protective layer 4 until it is electrically connected to chip 3.

[0032] In various types of clothing, the surface often features logos for identification and raised decorative elements for aesthetic purposes. These logos and decorative elements can be collectively referred to as tags. The improvement in this embodiment lies in that the protective layer 4 is a tag fixed to the garment body 1 and made of insulating material. Specifically, the protective layer 4 is made into the shape of the tag originally required for various types of clothing, and the chip 3 is encapsulated inside the tag. The connecting wires 6 can be conductive lines using the same conductive fibers as the antenna 2. The connecting wires 6 include a positive connecting wire 6 and a negative connecting wire 6. One end of each connecting wire 6 is inserted into the protective layer 4 and electrically connected to the positive and negative terminals of the chip 3, respectively. The other ends of each connecting wire 6 are electrically connected to the positive and negative terminals of the antenna, respectively. Thus, the antenna 2 and chip 3 are combined to form a complete RFID tag.

[0033] Preferably, the protective layer 4 can also cover all the antennas 2 inside the protective layer 4, or the protective layer 4 can cover the chip 3 and part of the antennas 2 at the location of the chip 3 inside the protective layer 4.

[0034] In the above embodiment, since the antenna 2 is formed by integrally weaving conductive fibers with the garment body 1, the antenna 2 has a porous mesh fabric structure. The protective layer 4 is preferably a flexible waterproof layer, such as rubber. When the protective layer 4 is in a liquid state, it can be coated on the chip 3, and the protective layer 4 can penetrate into the antenna 2 based on its own liquid fluidity, even penetrating to the back of the antenna 2 away from the chip 3. After the protective layer 4 is cured, it can be firmly bonded to the antenna 2 and the garment body 1, further reducing the risk of the protective layer 4 falling off the garment body 1.

[0035] Furthermore, the aforementioned protective layer 4 is a protective layer made of rubber.

[0036] Preferably, the chip 3 is arranged within the identification area 1.1.

[0037] In the above embodiments, the conductive fiber is a metal fiber, a carbon fiber, or a chemical fiber spun from a polymer mixed with a conductive medium. Specifically, the aforementioned chemical fiber refers to a chemical fiber with conductive properties obtained by adding conductive media such as carbon black, graphene, metal powder, or metal compounds to the fiber.

[0038] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

[0039] For those skilled in the art, various changes and modifications will undoubtedly be apparent after reading the above description. Therefore, the appended claims should be considered as covering all changes and modifications that encompass the true intent and scope of this utility model. Any and all equivalent scope and content within the scope of the claims should be considered as still falling within the intent and scope of this utility model.
