[0032] 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, NFC devices applied in different fields typically only possess NFC functionality adapted to their specific usage scenarios, resulting in limited functionality and hindering widespread adoption.

[0033] 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, as shown below. Figure 1 , Figure 2 As shown, the near-field communication device 1 includes a main structure 11 and an external interface 12. The main structure 11 includes a housing 111, a near-field communication module 112, and a main control module 113. The near-field communication module 112 and the main control module 113 are respectively assembled inside the housing 111, and the external interface 12 is located outside the housing 111. The main control module 113 is electrically connected to the external interface 12. The near-field communication module 112 includes a near-field communication tag 1121 and a near-field communication reader 1122. The first interface of the near-field communication tag 1121 and the second interface of the near-field communication reader 1122 are respectively connected to the main control module 113.

[0034] The aforementioned near-field communication module 112 includes a near-field communication tag 1121 and a near-field communication reader 1122. The first interface of the near-field communication tag 1121 and the second interface of the near-field communication reader 1122 are respectively connected to the main control module 113. The main control module 113 is electrically connected to the external interface 12. The aforementioned near-field communication device 1 integrates complete NFC tag and reading functions. It can access any NFC function through the main control module 113 and can also be externally connected to a terminal device via the external interface 12, improving the functional integration and ease of use of the near-field communication device 1. Specifically, the near-field communication tag 1121 is an NFC tag chip, and the near-field communication reader 1122 can be an NFC reader chip; both the NFC tag chip and the NFC reader chip are integrated into the near-field communication module 112.

[0035] In the above embodiments, the external interface 12 can be a standard Type-C interface, and the communication protocol can be a standard USB / UART communication protocol. The first and second interfaces can interface with the main control module 113 through the communication protocol. The main control module 113 can call the near-field communication tag 1121 and the near-field communication card reader 1122 as needed to realize the corresponding NFC function.

[0036] In some embodiments, the main structure 11 may further include a lighting component assembled within the housing 111. The lighting component is electrically connected to the main control module 113. The housing 111 has a light-transmitting area, through which light from the lighting component is emitted. The light emitted by the lighting component through the light-transmitting area can create a desired lighting atmosphere or indication effect for the near-field communication device 1, enhancing the user experience of the near-field communication device 1. Figure 2 The dashed arrow in the middle can represent the thickness direction of the housing 111. The position of the light-transmitting area in the thickness direction of the housing 111 can correspond to that of the light-transmitting area, or the light from the light-transmitting area can be transmitted through the light guide channel or light guide component.

[0037] For example, the lighting component may include a first indicator light associated with the operating status of the near-field communication module 112. The light-transmitting area includes a light-transmitting mark 1113 disposed in the center area of ​​the front sidewall of the housing 111, through which the light from the first indicator light shines. The operating status indicator light located in the center area of ​​the front sidewall is obtained through the first indicator light and the light-transmitting mark 1113 located in the center area of ​​the front sidewall of the housing 111. The first indicator light illuminates when the near-field communication module 112 is in an operating state and turns off when the near-field communication module 112 is in a non-operating state, improving both aesthetics and indication effectiveness.

[0038] Alternatively, the lighting component includes a second indicator light associated with the functional status of the near-field communication module 112. The light-transmitting area includes a light-transmitting ring 1114 disposed on the edge region of the front sidewall of the housing 111, through which the light from the second indicator light shines. A functional status indicator light located at the edge region of the front sidewall is obtained through the second indicator light and the light-transmitting ring 1114 located on the edge region of the front sidewall of the housing 111. When the near-field communication module 112 uses a first function, the second indicator light breathes; when the near-field communication module 112 uses a second function, the second indicator light flashes, improving both aesthetics and indication effectiveness.

[0039] Furthermore, such as Figure 3 As shown, the lighting component may include a first indicator light associated with the operating state of the near-field communication module 112 and a second indicator light associated with the functional state of the near-field communication module 112. The light-transmitting area includes a light-transmitting mark 1113 disposed in the center region of the front sidewall of the housing 111 and a light-transmitting ring 1114 disposed in the edge region of the front sidewall of the housing 111. The light from the first indicator light is emitted from the light-transmitting mark 1113, and the light from the second indicator light is emitted from the light-transmitting ring 1114, so that the lighting component and the light-transmitting area can achieve the indicating effect of the above two embodiments.

[0040] In the above embodiment, the projection of the housing 111 in the thickness direction can be circular. The circular housing 111 is aesthetically pleasing and occupies little space. The above-mentioned light-transmitting ring 1114, in conjunction with the circular housing 111, can achieve a lighting indication effect that matches the structure.

[0041] In other embodiments, the light-transmitting area can be set in different areas of the housing 111 according to specific appearance and indication requirements. The first indicator light can indicate the usage status by turning on, turning off, breathing, flashing, etc., and the second indicator light can indicate the functional status by turning on, turning off, breathing, flashing, etc. This application does not limit this.

[0042] In some embodiments, the central region of the front sidewall includes a planar structure 1112b, and the edge region of the front sidewall includes an arcuate structure 1112c that curves relative to the planar structure 1112b. The planar structure 1112b and the arcuate structure 1112c are respectively provided with light-transmitting areas to enhance the overall lighting effect of the near-field communication device 1. For example, the aforementioned light-transmitting mark 1113 can be located in the planar structure 1112b, and the light-transmitting ring 1114 can be located in the arcuate structure 1112c, with their lighting indication effects spaced apart and not interfering with each other.

[0043] In some embodiments, such as Figure 1 , Figure 4As shown, in the thickness direction of the housing 111, the housing 111 includes a front side 1112d and a back side 1111b disposed opposite to each other. The front side 1112d is provided with a near-field signal sensing area, and the back side 1111b is provided with a threaded mounting hole 14. The threaded mounting hole 14 is provided on the back side 1111b, which is away from the near-field signal sensing area, to avoid the influence of the installation of the near-field communication device 1 on the near-field signal sensing, and also to provide 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. When installing the near-field communication device 1, a stable assembly between the near-field communication device 1 and the terminal device can be achieved by screwing a threaded connector into the threaded mounting hole 14.

[0044] Furthermore, the back surface 1111b is also provided with positioning holes 15, and threaded mounting holes 14 and positioning holes 15 are alternately arranged in the edge area of ​​the back surface 1111b, so as to improve the installation accuracy of the near field communication device 1 by means of the arrangement of positioning holes 15 and threaded mounting holes 14, and avoid the near field communication device 1 from deviating from the expected installation position on the terminal device.

[0045] It should be noted that the aforementioned positioning hole 15 and threaded mounting hole 14 can be blind holes located on the back side 1111b to prevent foreign objects from entering the housing 111 by connecting the inside and outside of the housing. Furthermore, a boss corresponding to the positions of the positioning hole 15 and threaded mounting hole 14 can be provided on the inner surface of the housing 111, allowing the positioning hole 15 and threaded mounting hole 14 to pass through the housing 111 and form on the boss, thus increasing the depth of the positioning hole 15 and threaded mounting hole 14.

[0046] In the above embodiments, the near-field communication device 1 may further include a data transmission line 13. The first end 131 of the data transmission line 13 passes through the housing 111 and is electrically connected to the main control module 113. The external interface 12 is disposed at the second end 132 of the data transmission line 13. The data transmission line 13 increases the flexibility of the external interface 12 in connecting to the outside.

[0047] In some embodiments, the projection of the housing 111 in the thickness direction is circular, making the near-field communication device 1 compact and aesthetically pleasing. In the thickness direction of the housing 111, the housing 111 includes a base 1111 and a cover 1112. The base 1111 and the cover 1112 are fastened together to form the internal space of the housing 111. The near-field communication module 112 is assembled in the first space 1112a enclosed by the cover 1112, and the main control module 113 is assembled in the second space 1111a enclosed by the base 1111, reducing electromagnetic interference caused by structural interference between the near-field communication module 112 and the main control module 113.

[0048] Among them, such as Figure 3As shown, the outer diameter D of the projection of the aforementioned housing 111 in the thickness direction can range from 70mm to 80mm, for example, the outer diameter D can be 76mm. Figure 5 As shown, the thickness H of the housing 111 can range from 15mm to 25mm, for example, the thickness H of the housing 111 can be 19.5mm. The above size range allows the near-field communication device 1 to have a compact appearance and size, which does not require too much space during integration, thus improving the convenience of integration.

[0049] This application further provides a terminal device, which includes a device body and the aforementioned field communication device.

[0050] The near-field communication module 112 includes a near-field communication tag 1121 and a near-field communication reader 1122. The first interface of the near-field communication tag 1121 and the second interface of the near-field communication reader 1122 are respectively connected to the main control module 113. The main control module 113 is electrically connected to the external interface 12. The aforementioned near-field communication device 1 integrates complete NFC tag and reading functions. It can access any NFC function through the main control module 113 and can also be externally connected to terminal devices via the external interface 12, improving the functional integration and ease of use of the near-field communication device 1. The aforementioned near-field communication device 1 has complete and comprehensive functional modes, standard interfaces and communication protocols, and requires little space, making it easy to integrate into other terminal devices, facilitating the rapid deployment and adoption of the near-field communication device 1 and terminal devices.

[0051] 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.
