[0030] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0031] The embodiment of the present utility model discloses an enhanced NFC communication device.

[0032] Embodiment 1

[0033] The present utility model provides as Figures 1-5An enhanced NFC communication device shown includes a device housing 1. An annular groove 22 is formed on the outer wall of the device housing 1, and an anti-interference ring 23 is fixedly embedded inside the annular groove 22. An embedding groove 2 is formed on the outer wall of the device housing 1, and an NFC communication module 3 is fixedly arranged on the inner wall of the embedding groove 2. A plurality of cover plates 4 are in contact with and cover the outer wall of the device housing 1. Sealing rings 17 are fixedly sleeved on the outer walls of the plurality of cover plates 4. The sealing rings 17 are in contact and cooperate with the outer wall of the device housing 1. The plurality of sealing rings 17 are arranged in cooperation. Placing grooves are formed on the outer walls of the plurality of sealing rings 17, and adsorption magnetic strips 24 are fixedly arranged on the inner walls of the placing grooves. An internally threaded tube 5 is fixedly penetrated through the inside of the cover plate 4. A plurality of sliding grooves 6 are formed on the outer wall of the device housing 1. The pipe wall of the internally threaded tube 5 is arranged inside the sliding groove 6, and an elastic sliding mechanism is arranged between the pipe wall of the internally threaded tube 5 and the inside of the sliding groove 6. The elastic sliding mechanism includes a slider 8. The slider 8 is slidably arranged inside the sliding groove 6. A guide rod 9 is fixedly arranged on the inner wall of the sliding groove 6. The slider 8 is slidably sleeved on the outer side of the guide rod 9. A first spring 10 is sleeved on the rod wall of the guide rod 9. Two ends of the first spring 10 are respectively fixedly connected with the guide rod 9 and the slider 8.

[0034] When the device is in use, a plurality of the external cover plates 4 are in contact with each other to cover the embedding groove 2. At this time, the NFC communication module 3 is arranged inside the embedding groove 2 and is protected by the plurality of cover plates 4. At the same time, under the cooperation of the plurality of sealing rings 17 and the bonding of the adsorption magnetic strips 24, the cover plates 4 can effectively seal and shield the NFC communication module. When communication work needs to be carried out, a device such as a mobile phone can be brought close to the device housing 1. At this time, the plurality of cover plates 4 move under the connection of the internally threaded tube 5 and the slider 8. When the slider 8 slides inside the sliding groove 6, it is supported by the guide rod 9, and the first spring 10 is stretched, so that the plurality of cover plates 4 move away from each other and the embedding groove 2 is opened. At this time, the device can be in direct contact with the NFC communication module 3, enhancing the communication effect. At the same time, in cooperation with the anti-interference ring 23, the communication stability can be further improved.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, in Embodiment 2, in order to enable the plurality of cover plates 4 to move quickly when the device approaches the device housing 1, so that the NFC communication module 3 is exposed and used, as Figures 1-2 and Figure 4 shown, a pushing ring 7 is covered on the outer sides of the plurality of cover plates 4. A pushing and separating mechanism is arranged between the pushing ring 7 and the cover plates 4. The pushing and separating mechanism includes a push plate 13. A support sleeve 14 is fixedly sleeved on the outer wall of the pushing ring 7. Two mounting plates 15 are fixedly arranged on the outer wall of the cover plate 4. A support rod 16 is fixedly arranged between the two mounting plates 15. Two ends of the push plate 13 are respectively rotatably sleeved on the outer sides of the support sleeve 14 and the support rod 16.

[0037] When the device approaches the device housing 1, the device contacts the pushing ring 7. At this time, the pushing ring 7 can push the push plate 13 under the support of the support sleeve 14. The push plate 13 rotates relative to the support rod 16. Then, when the pushing ring 7 is pushed, a plurality of cover plates 4 can be synchronously driven, so that the cover plates 4 move quickly to expose and use the NFC communication module 3.

[0038] Embodiment 3

[0039] On the basis of Embodiment 1, in order to facilitate the maintenance of the NFC communication module 3, as Figures 1-2 and Figure 4 shown, an internal thread groove 11 is formed on the surface of the slider 8. The internal thread tube 5 and the internal thread groove 11 are jointly provided with a positioning screw 12 through their internal threads. The end of the positioning screw 12 passes through the internal thread tube 5 and extends to the outside. Two symmetrically arranged positioning grooves 18 are formed on the rod wall of the positioning screw 12. Two symmetrically arranged positioning rods 19 are slidably penetrated through the tube wall of the internal thread tube 5. The positioning rods 19 are inserted and matched with the positioning grooves 18. A second spring 20 is sleeved on the rod wall of the positioning rod 19. The two ends of the second spring 20 are respectively fixedly connected with the internal thread tube 5 and the positioning rod 19. Pulling rings 21 are fixedly embedded at the ends of a plurality of positioning rods 19.

[0040] When it is necessary to disassemble and use the NFC communication module 3, the disassembly of a plurality of positioning screws 12 can be carried out in this way. First, the positioning rods 19 on both sides of the positioning screw 12 are pulled, so that the positioning rods 19 move horizontally and stretch the second spring 20. When the positioning rods 19 are pulled out from the inside of the positioning grooves 18, the positioning screw 12 can be rotated, so that the positioning screw 12 is far away from the internal thread tube 5 and the internal thread groove 11 on the surface of the slider 8. At this time, the cover plate 4 is separated from the device housing 1 to facilitate the maintenance of the NFC communication module 3. After the NFC communication module 3 is installed, the positioning screw 12 can be inserted into the internal thread tube 5 and the slider 8, and the positioning rods 19 are inserted into the positioning grooves 18 to complete the position determination of the cover plate 4, ensuring the stable use of the device.

[0041] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
