Description

Technical Field

[0001] This application belongs to the field of badminton racket technology, specifically relating to an anti-counterfeiting NFC tag and a badminton racket handle using the tag. Background Technology

[0002] The handle of a badminton racket is the part that directly contacts the user, significantly impacting control, comfort, and shot performance. It is made of specific materials; currently, the most common racket handle materials on the market are wood, carbon fiber composite, and organic polymer materials. Structurally, the handle also serves as the connection between the racket body and the brand's anti-counterfeiting back cover.

[0003] Currently, most badminton rackets on the market primarily use three methods: traditional holographic anti-counterfeiting labels, laser engraving of customized font numbers, and structural designs using injection molding of multiple materials for the racket cover and bottom cover.

[0004] The current anti-counterfeiting system in the badminton racket market faces severe challenges, with mainstream technologies revealing systemic vulnerabilities. The industry-standard holographic anti-counterfeiting labels, due to their publicly available technology, can be replicated with high precision, and laser-engraved batch numbers can be reverse-engineered to bypass parameter detection. Furthermore, the only system with physical anti-counterfeiting features—the bottom cover manufacturing process—requires significant investment in the precision injection molding and mold development of special composite materials, giving rise to a gray market of "re-fitting" rackets. Counterfeiters collect broken rackets or worn-out genuine secondhand rackets, remove the original bottom cover, and transplant it onto counterfeit products, creating deceptively genuine "semi-genuine, semi-fake" rackets. This mixed distribution model not only renders conventional authentication methods ineffective but also leads to a vicious cycle of "bad money driving out good," severely damaging consumer rights and discouraging brand owners' enthusiasm for technological research and development. Utility Model Content

[0005] The technical problem this application aims to solve is to overcome the shortcomings of existing technologies and provide an anti-counterfeiting NFC tag and a badminton racket handle using the tag. The NFC tag of this application connects the handle body and the racket bottom cover, forming a tight and inseparable whole. Once the racket bottom cover is peeled off, the NFC electronic tag's detection function will record this change, and the status cannot be modified, thus effectively preventing transplantation and tampering. This application of NFC technology effectively prevents counterfeiting of badminton rackets.

[0006] The technical solution adopted by this application to solve its existing problems is:

[0007] An anti-counterfeiting NFC tag includes interconnected coils and detection lines, wherein a portion of the detection lines is provided with detection line slits.

[0008] A badminton racket handle, based on the aforementioned anti-counterfeiting NFC tag, includes a wooden handle.

[0009] The bottom of the wooden handle is recessed with an end plug opening, and an NFC electronic tag is placed inside the end plug opening. The opening of the end plug opening is sealed by a bottom cover.

[0010] Preferably, the detection line is fixedly connected to the inner wall of the end plug opening.

[0011] Preferably, the detection line is fixedly connected to the inner wall of the end plug opening by adhesive bonding.

[0012] Preferably, a wooden handle end plug is inserted inside the end plug opening, and the detection line is clamped between the wooden handle end plug and the end plug opening.

[0013] The coil is located at the end of the wooden handle plug facing the bottom cover.

[0014] Preferably, the coil is fixedly connected to the bottom cover.

[0015] Preferably, the coil is fixedly connected to the bottom cover by adhesive.

[0016] Preferably, the wooden handle has a central rod opening at the end away from the bottom cover, and the surface of the wooden handle has a fixing screw hole that is connected to the central rod opening.

[0017] Compared with the prior art, the beneficial effects of this application are as follows:

[0018] (1) A low-density EPDM rubber end plug is inserted into the bottom of the badminton racket handle. This not only serves to fix the electronic tag detection line, but also allows the weight to be flexibly controlled according to the depth of the hole at the bottom of the handle, increasing or decreasing the racket's balance point, thus adapting to various types of badminton rackets such as offensive and speed rackets.

[0019] (2) After purchasing a racket, consumers can use an NFC-enabled mobile phone to read the NFC electronic tag to obtain detailed product information. At the same time, racket sellers can add promotional information to the reading page. If the bottom cover is removed, an anomaly warning will be displayed when the consumer reads the tag, effectively preventing counterfeiting. Through the application of NFC technology, an effective traceability and anti-counterfeiting control mechanism is established to prevent consumers from purchasing counterfeit rackets.

[0031] The attached figure shows a preferred embodiment of the NFC tag for anti-counterfeiting authentication and the badminton racket handle using the tag. The following is a more detailed description of this application in conjunction with the attached figure.

[0032] Depend on Figures 6 to 9 As shown, an anti-counterfeiting NFC tag includes a coil 301 and a detection line 302 that are interconnected, and a portion of the detection line 302 is provided with a detection line cutter 303.

[0033] Depend on Figures 1 to 5 As shown, a badminton racket handle includes a wooden handle 1. The bottom of the wooden handle 1 is recessed with an end plug opening 101, and the end of the wooden handle 1 away from the bottom cover 4 is provided with a shaft opening 103. The shaft opening 103 and the end plug opening 101 are arranged with their ends open, but they are not connected in the middle. The wooden handle 1 is an octagonal cone.

[0034] The bottom cover 4 is made of ABS-PP composite material, with an octagonal hole in the middle for connecting the bottom of the wooden handle 1, which serves to protect the NFC electronic tag 3 and prevent moisture from corroding the wooden handle 1.

[0035] An NFC electronic tag 3 is housed inside the end plug opening 101, and the opening of the end plug opening 101 is sealed by the bottom cover 4. The NFC electronic tag 3 with detection function adds a detection mechanism to the traditional NFC tag, enabling the tag's status to be monitored through NFC-enabled mobile phone reading. The tag typically includes a detection line 302, an NFC chip, and an antenna 301. The detection line 302 is generally designed as a fragile wire; when the packaging is opened, the detection line 302 breaks, triggering the NFC chip to record this change. The NFC chip communicates with external devices through the antenna, allowing it to read or write relevant information, such as packaging opening status and anti-counterfeiting information. This design greatly enhances the reliability and security of anti-counterfeiting traceability. This type of tag is also commonly referred to as a packaging opening information management NFC electronic tag 3.

[0036] The NFC electronic tag 3 includes an interconnected coil 301 and a detection line 302, the detection line 302 being fixedly connected to the inner wall of the end plug opening 101. Further, the detection line 302 is fixedly connected to the inner wall of the end plug opening 101 by adhesive. A portion of the detection line 302 is provided with a detection line slit 303.

[0037] A wooden handle end plug 2 is inserted into the end plug opening 101. The detection line 302 is sandwiched between the wooden handle end plug 2 and the end plug opening 101. The coil 301 is located at the end of the wooden handle end plug 2 facing the bottom cover 4. The wooden handle end plug 2 is made of low-density ethylene propylene rubber, which has a certain degree of elasticity, and is a cylinder.

[0038] During assembly, first insert the detection line 302 into the end plug opening 101 and stick it. After sticking, insert it into the wooden handle end plug 2. Finally, bend the coil 301 of the NFC electronic tag 3, with the coil 301 part at the top of the wooden handle end plug 2.

[0039] The coil 301 is fixedly connected to the bottom cover 4. Furthermore, the coil 301 is fixedly connected to the bottom cover 4 by adhesive.

[0040] The bottom cover 4 is pre-grooved during manufacturing to facilitate assembly with the bottom of the wooden handle 1. Before assembly, a two-component polyurethane adhesive is applied to the surface of the coil 301 of the NFC electronic tag 3, and then the bottom cover 4 is inserted, ensuring that the adhesive adheres to the bottom cover 4. When the bottom cover 4 is separated from the wooden handle 1, the coil 301 is removed together with the bottom cover 4, and the detection line 302 remains in the opening 101 at the end of the wooden handle. When the detection line 302 is disconnected, the tag chip records the removal of the bottom cover 4. When the consumer reads the tag, it indicates that the bottom cover has been moved, thus achieving the purpose of anti-counterfeiting.

[0041] During the production of the NFC electronic tag 3, the antenna 301 uses a PET substrate. At the same time, the detection line 302 part is designed with a fragile antenna by adding a detection line cutter 303. The finished tag is only partially coated with glue on the detection line 302 part, making the tag detection line 302 difficult to remove. If it is removed, it will break at the detection line cutter 303.

[0042] The surface of the wooden handle 1 has a fixing screw hole 102 that connects to the shaft opening 103. Besides being designed according to the normal dimensions of a racket handle, the bottom of the wooden handle 1 has a pre-drilled end plug opening 101, and the diameter of the opening must match the dimensions of the NFC electronic tag coil 301 and the wooden handle end plug 2. Simultaneously, the depth of the opening must match the length of the detection line 302 of the NFC electronic tag 3. The wooden handle end plug 2, made of lightweight rubber, is used to fill the hole, avoiding any impact on the handle's quality and balance. The top of the wooden handle 1 has a shaft opening 103 that matches the shaft diameter. Before inserting the shaft, thermoplastic adhesive is injected. After the shaft is inserted, self-tapping screws are screwed into the pre-drilled fixing screw hole 102 to secure the shaft and prevent the entire wooden handle from being retracted.

[0043] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
