Description

Technical Field

[0001] This utility model relates to the field of NFC technology, specifically to a pendant with an NFC chip. Background Technology

[0002] Personal accessories (keychains, name tags, luggage tags, etc.) are increasingly being given electronic functions, such as access control, payment, or product traceability. Existing accessories with NFC chips have the following pain points: 1. The chip is directly exposed and is susceptible to failure due to impact or bending; 2. The chip cavity is sealed with screws or glue, which makes it difficult for users to replace and easily leads to the scrapping of the entire component; 3. The suspension components (ropes, rings) are fixedly riveted or knotted to the main body, making disassembly and assembly difficult, and they are prone to fatigue fracture after repeated bending.

[0003] Based on the above, this utility model proposes a pendant with an NFC chip, which can effectively solve the above problems. Utility Model Content

However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0014] Example 1: like Figures 1 to 4As shown, this utility model provides a pendant with an NFC chip, including a pendant body 1, a hanging member 2 snapped onto the pendant body 1, a chip slot 11 opened on the side of the pendant body 1, a chip holder 3 embedded in the chip slot 11, a sleeve 4 fixedly mounted on the side of the chip holder 3, a first connecting rod 5 slidably connected inside the sleeve 4, a second connecting rod 6 rotatably connected to the left side of the first connecting rod 5, the middle part of the second connecting rod 6 rotatably connected to a fixed shaft 7, the fixed shaft 7 being fixedly connected to the chip slot 11, and an NFC tag chip 8 snapped into the chip holder 3.

[0015] Example 2: like Figures 1 to 4 As shown, this utility model provides a pendant with an NFC chip, including a pendant body 1, a hanging member 2 snapped onto the pendant body 1, a chip slot 11 opened on the side of the pendant body 1, a chip holder 3 embedded in the chip slot 11, a sleeve 4 fixedly mounted on the side of the chip holder 3, a first connecting rod 5 slidably connected inside the sleeve 4, a second connecting rod 6 rotatably connected to the left side of the first connecting rod 5, the middle part of the second connecting rod 6 rotatably connected to a fixed shaft 7, the fixed shaft 7 being fixedly connected to the chip slot 11, and an NFC tag chip 8 snapped into the chip holder 3; The pendant body 1, the suspension part 2, the chip slot 11, the sleeve 4, the first connecting rod 5, and the second connecting rod 6 form a "side push lever" quick-release system: gently push the first connecting rod 5 inward → the second connecting rod 6 rotates around the fixed axis 7 → the end of the lever lifts the chip seat 3 → the NFC tag chip 8 pops out with the chip seat 3, realizing tool-free, single-finger operation, and the chip is always covered in the slot to avoid drop impact; The chip holder 3 includes an outer plate 31 and a mounting plate 32. The mounting plate 32 is disposed on one side of the outer plate 31. A plurality of limiting plates 33 are rotatably connected to the mounting plate 32. The NFC tag chip 8 is mounted on the mounting plate 32 through the limiting plates 33. The chip holder 3 adopts the structure of "outer plate 31 + mounting plate 32 + rotating limiting plate 33": the limiting plate 33 rotates inward → the NFC tag chip 8 is placed in → the limiting plate 33 rotates in the opposite direction and fastens the four sides of the chip, forming a four-sided enclosure; Furthermore, in another embodiment, the outer plate 31 is provided with a through hole 311 that matches the first connecting rod 5; the first connecting rod 5 can be directly held in place by a tool through the through hole 311, improving convenience; Furthermore, in another embodiment, the suspension member 2 includes a hanging rope 21 and a connecting block 22.
