[0028] NFC (Near Field Communication) is a short-range wireless communication technology that enables secure data exchange over short distances through electromagnetic induction coupling. NFC devices offer significant advantages in security, response speed, and power consumption, making them widely used in smart retail, medical monitoring, transportation, and smart homes. However, the electromagnetic signals generated by the NFC functional module and the main control module of the near field communication device during operation can easily cause mutual interference. The NFC functional module can also be affected by interference from terminal devices, impacting the communication performance of the near field communication device.

[0029] This application provides a near-field communication device. Figure 1 This is a three-dimensional structural diagram of a near-field communication device according to an exemplary embodiment of this application. Figure 2 This is an exploded structural diagram of a near-field communication device according to an exemplary embodiment of this application. Figure 3 This is an exploded structural diagram of a near-field communication device from another angle, according to an exemplary embodiment of this application. Figure 4 This is a partial cross-sectional structural diagram of a near-field communication device according to an exemplary embodiment of this application, as shown below. Figures 1-4 As shown, Figure 2 , Figure 4 The dashed arrow in the diagram represents a first direction. The near-field communication device 1 includes a housing 11, a near-field communication module 12, a main control module 13, and a shielding structure 14. The near-field communication module 12, the main control module 13, and the shielding structure 14 are assembled within the housing 11. The near-field communication module 12 and the main control module 13 are distributed along the first direction. In the first direction, the shielding structure 14 is located between the near-field communication module 12 and the main control module 13, and the shielding structure 14 projects onto at least one of the near-field communication module 12 and the main control module 13 to isolate electromagnetic radiation between the main control module 13 and the near-field communication module 12. The first direction may be the thickness direction of the housing 11.

[0030] The aforementioned near-field communication device 1 includes a shielding structure 14. In the distribution direction of the near-field communication module 12 and the main control module 13, the shielding structure 14 is located between the near-field communication module 12 and the main control module 13, and the shielding structure 14 forms a projection on at least one of the near-field communication module 12 and the main control module 13, thereby isolating the electromagnetic radiation between the main control module 13 and the near-field communication module 12, avoiding mutual interference between the main control module 13 and the near-field communication module 12, and helping to improve the performance of the near-field communication device 1.

[0031] In some embodiments, the near-field communication module 12 includes a first side facing the main control module 13, and a shielding structure 14 is assembled on the first side. Assembling the shielding structure 14 on the first side of the near-field communication module 12 helps to simplify the structural setup, accurately prevent electromagnetic signals emitted by the main control module 13 from acting on the near-field communication module 12, and prevent electromagnetic signals emitted by the near-field communication module 12 from acting on the main control module 13, thereby improving shielding reliability.

[0032] In the above embodiments, the shielding structure 14 can be a sheet structure or a membrane structure, and this application does not limit it in this regard. The material of the shielding structure 14 can be metal, composite material with shielding properties, etc., and this application does not limit it in this regard either.

[0033] In some embodiments, the shielding structure 14 may be a shielding film attached to the first side. The shielding film is thin and the attachment process is simple, which helps to simplify the installation cost of the shielding structure 14.

[0034] In the above embodiments, the shielding structure 14 can cover the first side to enhance the shielding effect. Alternatively, if the impact on the shielding effect is minimal, the shielding structure 14 can also be assembled onto a portion of the first side. For example, the shielding structure 14 can avoid the mounting structure of the near-field communication module 12 or the non-communication area of ​​the near-field communication module 12.

[0035] In other embodiments, the shielding structure 14 may also be a box-shaped structure that covers the near-field communication module 12 to avoid signal interference between the near-field communication module 12 and the main control module 13.

[0036] In some embodiments, the shielding structure 14 can also be assembled onto the main control module 13 to shield the electromagnetic signals between the main control module 13 and the near-field communication module 12. For example, the shielding structure 14 can be a box-shaped structure covering the main control module 13.

[0037] Alternatively, the main control module 13 may include a second side facing the near-field communication module 12, and the shielding structure 14 may be a shielding film attached to the second side. The shielding structure 14 may cover the second side to enhance the shielding effect. If the impact on the shielding effect is minimal, the shielding structure 14 may also be assembled onto a portion of the second side.

[0038] In some embodiments, the housing 11 includes a base 111 and a cover 112, the base 111 and the cover 112 being fastened together. The cover 112 is provided with a near-field signal sensing area, and the base 111 is provided with a mounting portion 17. The mounting portion 17 is located on the back side away from the near-field signal sensing area, which avoids the impact of the installation of the near-field communication device 1 on the near-field signal sensing and also provides sufficient operating space for the installation of the near-field communication device 1. After the near-field communication device 1 and the terminal are assembled, the near-field signal sensing area faces the user, thus facilitating use.

[0039] The mounting part 17 can be a threaded hole, a snap-fit ​​structure, or a magnetic structure, and this application does not limit this. When the mounting part 17 is a threaded hole, a stable assembly between the near-field communication device 1 and the terminal equipment can be achieved by screwing a threaded connector into the threaded mounting hole.

[0040] Furthermore, the near-field communication module 12 can be assembled in the first space 1121 enclosed by the cover 112, and the main control module 13 can be assembled in the second space 1111 enclosed by the base 111. The second space 1111 of the base 111 provides installation space for the main control module 13, reduces mutual interference between the main control module 13 and the near-field communication module 12, and also utilizes the thickness of the base 111 to form shielding and isolation between the terminal device and the near-field communication module 12, which helps to further avoid signal interference from external terminal devices to the near-field communication module 12.

[0041] In some embodiments, in the thickness direction of the housing 11, the second depth of the second space 1111 can be greater than the first depth of the first space 1121. On the one hand, the second space 1111 can provide sufficient installation space for the main control module 13, and on the other hand, the depth of the second space 1111 increases the shielding distance between the near-field communication module 12 and the terminal device, which helps to improve the shielding effect.

[0042] In some embodiments, the housing 11 has a circular cross-sectional shape in the direction perpendicular to its thickness, making the near-field communication device 1 compact and aesthetically pleasing. A gap is provided between the near-field communication module 12 and the edge of the first space 1121, so as to reduce the interference of the external environment on the near-field communication module 12 by utilizing the peripheral gap formed between the circular edge and the near-field communication module 12.

[0043] In the above embodiments, in the first direction, the projections of at least a portion of the main control module 13 and at least a portion of the near-field communication module 12 can be staggered to reduce signal interference between the main control module 13 and the near-field communication module 12.

[0044] In some embodiments, the near-field communication device 1 further includes a data transmission line 15. The first end of the data transmission line 15 passes through the base 111 and is electrically connected to the main control module 13. The second end of the data transmission line 15 is provided with an external interface 16, which increases the flexibility of the external interface 16 in connecting to the outside.

[0045] In the above embodiments, the near-field communication module 12 may include a near-field communication tag 121 and a near-field communication reader 122. The first interface of the near-field communication tag 121 and the second interface of the near-field communication reader 122 are respectively connected to the main control module 13. The near-field communication device 1 integrates complete NFC tag and reading functions. It can access any NFC function through the main control module 13 and can also be connected to a terminal device via the external interface 16, improving the functional integration and ease of use of the near-field communication device 1. The near-field communication tag 121 is an NFC tag chip, and the near-field communication reader 122 can be an NFC reader chip. The NFC tag chip and the NFC reader chip are integrated into the near-field communication module 12.

[0046] This application further provides a terminal device, which includes a device body and the aforementioned near-field communication device 1.

[0047] The near-field communication device 1 includes a shielding structure 14. In the distribution direction of the near-field communication module 12 and the main control module 13, the shielding structure 14 is located between the near-field communication module 12 and the main control module 13, and the shielding structure 14 forms a projection on at least one of the near-field communication module 12 and the main control module 13, isolating the electromagnetic radiation between the main control module 13 and the near-field communication module 12, avoiding mutual interference between the main control module 13 and the near-field communication module 12, and helping to improve the performance of the near-field communication device 1.

[0048] It should be noted that the aforementioned terminal equipment can be vending machines, cash registers, takeaway lockers, etc., and this application does not impose any restrictions on this.
