[0047] 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 incorporate multiple functional components, including NFC itself, interactive lighting, and a control motherboard. This complexity leads to higher internal structure, cost, and a higher failure rate.
[0048] This application provides a near-field communication device. Figure 1This is a three-dimensional exploded view of a near-field communication device according to an exemplary embodiment of this application, as shown below. Figure 1 As shown, the near-field communication device 1 includes a housing 11 and an integrated control module 12, which is assembled inside the housing 11. The integrated control module 12 includes a circuit board 121, a near-field communication module 126, a main control module 127, a light source assembly 125, and an external interface 129. The near-field communication module 126, the light source assembly 125, and the main control module 127 are assembled on the circuit board 121. The main control module 127 is electrically connected to the near-field communication module 126, the light source assembly 125, and the external interface 129. The housing 11 has a light-transmitting portion for allowing light from the light source assembly 125 to pass through.
[0049] The above solution integrates near-field communication, lighting, and main control functions onto the circuit board 121, and provides an external interface 129 for power supply and communication with the outside world. This reduces the types and quantities of materials, lowers the complexity of the internal structure of the near-field communication device 1, and helps to simplify assembly and reduce costs.
[0050] In some embodiments, the near-field communication device 1 further includes a light guide component 122, which cooperates with the light source component 125 and the light transmission portion to guide the light from the light source component 125 to the light transmission portion and then transmit it through the light transmission portion. The light guide component 122 can be used to conduct light between the light source component 125 and the light transmission portion, which helps to optimize the light propagation path and improve the flexibility of the placement of the light source component 125 and the light transmission portion.
[0051] The light-transmitting portions of the housing 11 can be distributed in the same area or multiple different areas of the housing 11. The light source assembly 125 can have one, two, or multiple light sources, and the light guide assembly 122 can include one, two, or multiple light guides. When the light-transmitting portions are located in the same area of the housing 11, the light source assembly 125 has one light source, and the light guide assembly 122 has one light guide, light can be propagated to the light-transmitting portions located in the same area through the light guide.
[0052] When the light-transmitting portions are located in different areas of the housing 11, the light source assembly 125 has two or more light sources, and the light guide assembly 122 has multiple light guides, the light sources can be divided into at least two groups, with each group of light sources transmitting light to the light-transmitting portions located in different areas through a light guide. The light source distribution of the light source assembly 125 and the structure and arrangement of the light guide assembly 122 can be configured according to specific light output requirements, and this application does not impose any limitations on this.
[0053] It should be noted that the above-mentioned light source component 125 can be in the form of lamp beads, lamp strips, etc., and the light source of the light source component 125 can be LED light source, OLED light source, etc., and this application does not limit it.
[0054] For example Figure 2 , Figure 3 As shown, the circuit board 121 includes a first side surface 1211 and a second side surface 1212 disposed opposite to each other. The light source assembly 125 includes a first LED 1251 assembled on the first side surface 1211 and a second LED 1252 assembled on the second side surface 1212. The light guide assembly 122 includes a first light guide 1221 and a second light guide 1222. The light-transmitting portion includes a first light-transmitting area 1131 and a second light-transmitting area 1132. The first light guide 1221 has a first light-incident surface that cooperates with the first LED 1251 and a first light-exiting surface that cooperates with the first light-transmitting area 1131. The second light guide 1222 has a second light-incident surface that cooperates with the second LED 1252 and a second light-exiting surface that cooperates with the second light-transmitting area 1132. Distributing the first LED 1251 and the second LED 1252 on opposite sides of the circuit board 121 can reduce structural and light emission interference between the first LED 1251 and the second LED 1252, which helps to optimize the distribution position of the light guide assembly 122. Based on the placement of the first LED 1251 and the second LED 1252, the integrated control module 12 forms a stacked distribution structure, reducing space occupation. The first light guide 1221 transmits the light from the first LED 1251 to the first light-transmitting area 1131, and the second light guide 1222 transmits the light from the second LED 1252 to the second light-transmitting area 1132, effectively preventing light interference between the first LED 1251 and the second LED 1252.
[0055] like Figure 4 , Figure 5 As shown, the circuit board 121, the first light guide 1221, and the second light guide 1222 can be plate-shaped structures to reduce space occupation. The first light guide 1221 is disposed on the inner side of the first side 1211 of the circuit board 121, and the circuit board 121 can be located in the hollow area at the center of the second light guide 1222 to reduce space occupation in the thickness direction. The first light guide 1221 and the second light guide 1222 can be fixed to each other or to the housing 11 by snap-fit, which can effectively reduce material costs and production assembly costs.
[0056] In one embodiment, the first side surface 1211 includes a first region covered by the first light guide 1221 and a second region located around the first region, with the first LED bead 1251 disposed in the second region. The first light-transmitting region 1131 includes a first light-transmitting sub-region 1131a located at the center of the housing 11 and a second light-transmitting sub-region 1131b extending from the periphery of the first light-transmitting sub-region 1131a toward the edge of the housing 11. The light emission direction of the first group of first LED beads 1251 is toward the center of the circuit board 121 to obtain a light-emitting effect in the first light-transmitting sub-region 1131a. The light emission direction of the second group of first LED beads 1251 is toward the edge of the circuit board 121 to obtain a light-emitting effect in the second light-transmitting region 1131b. The first LED 1251 is placed around the first light guide 1221. The first LED 1251 is grouped together. By different light emission directions, light emission effects can be obtained in the first light-transmitting sub-region 1131a located at the center of the housing 11 and the second light-transmitting sub-region 1131b extending toward the edge of the housing 11, which helps to improve the light emission uniformity of different light-transmitting sub-regions.
[0057] In one embodiment, the edge of the first light guide 1221 is provided with a plurality of circumferentially distributed clearance notches 1221a, and the second group of first lamp beads 1251 are respectively embedded in the clearance notches 1221a, which effectively reduces the light transmission path, improves the light guiding effect, and ensures that the cursor formed by each second light-transmitting sub-region 1131b is bright and uniform.
[0058] For example, for the first light-transmitting area 1131, which is relatively large and dispersed, and where the first LED beads 1251 are concentrated on the first side 1211 of the smaller circuit board 121, in order to ensure the brightness and uniformity of the lighting effect in all lit areas, the first LED beads 1251 can be divided into two groups. The first group of four LED beads emits light towards the center and illuminates the first light-transmitting sub-area 1131a. The second group of four LED beads emits light towards the outer ring, and each LED bead illuminates a second light-transmitting sub-area 1131b. To improve the light transmission efficiency, these four LED beads are embedded in the clearance notch 1221a of the first light guide 1221, which effectively reduces the light transmission path, improves the light guiding effect, and ensures that the cursor formed by each second light-transmitting sub-area 1131b is bright and uniform.
[0059] In such Figure 6 , Figure 7In the illustrated embodiment, the second LED beads 1252 are distributed in the edge region of the second side surface 1212, and the second light guide 1222 includes an annular structure located around the circuit board 121. The light emission direction of the second LED beads 1252 is towards the second light guide 1222, so as to form a lighting effect in the annular second light-transmitting area 1132 at the edge of the housing 11. For example, there can be 12 second LED beads 1252, and the 12 second LED beads 1252 can be evenly distributed in the edge region of the circuit board 121.
[0060] In such Figure 8 , Figure 9 In the illustrated embodiment, the first light-transmitting sub-region 1131a can be a logo, letter, text, graphic, or other identifying shape. The second light-transmitting sub-region 1131b includes a strip-shaped structure extending from the periphery of the identifying shape toward the edge of the housing 11, so as to obtain the desired lighting effect through the first light-transmitting sub-region 1131a and the second light-transmitting sub-region 1131b. In other embodiments, the second light-transmitting sub-region 1131b can also be circular, polygonal, irregular, or other shapes.
[0061] The light from the first LED 1251 can be emitted from the first light-transmitting area 1131 to serve as an indicator of the working status of the near-field communication device 1. When the near-field communication module 126 is in working condition, the first LED 1251 is lit; when the near-field communication module 126 is not in working condition, the first LED 1251 is off, improving aesthetics and indicating effectiveness. The light from the second LED 1252 can be emitted from the second light-transmitting area 1132 to serve as an indicator of the function status of the near-field communication device 1. When the near-field communication module 126 uses the near-field communication tag function, the second LED 1252 is in a breathing state; when the near-field communication module 126 uses the near-field communication card reader function, the second LED 1252 flashes, improving aesthetics and indicating effectiveness. In other embodiments, the first LED 1251 can indicate its usage status by being lit, turned off, breathing, or flashing, and the second LED 1252 can indicate its function status by being lit, turned off, breathing, or flashing. This application does not limit this.
[0062] The first LED 1251 and the second LED 1252 mentioned above can be controlled by independent control circuits, which simplifies the control logic and makes it easier to achieve different lighting effects.
[0063] In the above embodiments, the light emission direction of the first LED 1251 is parallel to the first side surface 1211, and / or the light emission direction of the second LED 1252 is parallel to the second side surface 1212. The side-emitting method of the first LED 1251 and / or the second LED 1252 can increase the light coverage area, which is beneficial for reducing the size of the circuit board 121, so that the desired lighting effect can be achieved with a smaller circuit board 121 and the first LED 1251 and second LED 1252 located on the circuit board 121.
[0064] In some embodiments, the first light-emitting surface includes a first plate facing the first light-transmitting area 1131, and the first light guide 1221 includes a second plate facing away from the first plate, the second plate being provided with a first reflective layer 123. Providing the first reflective layer 123 on the side of the first light guide 1221 facing away from the first light-transmitting area 1131 can reflect all light onto the light-emitting surface, improving luminous efficiency and the uniformity of the lighting effect.
[0065] The first reflective layer 123 may include a main body portion 1231 and an extension portion 1232. In the thickness direction of the circuit substrate 121, the projection of the main body portion 1231 is located on the circuit substrate 121, and the projection of the extension portion 1232 is located outside the circuit substrate 121, so as to isolate the light of the first lamp bead 1251 and the second lamp bead 1252 and avoid light crosstalk between the first lamp bead 1251 and the second lamp bead 1252.
[0066] In some embodiments, the second light-emitting surface includes a third plate surface disposed facing the second light-transmitting area 1132, and the second light guide 1222 includes a fourth plate surface facing away from the third plate surface, the fourth plate surface being provided with a second reflective layer 124. By disposing of the second reflective layer 124 on the side of the second light guide 1222 facing away from the second light-transmitting area 1132, all light can be reflected onto the light-emitting surface, improving luminous efficiency and the uniformity of the lighting effect.
[0067] It should be noted that the first reflective layer 123 and the second reflective layer 124 mentioned above can be white high-gloss reflective films.
[0068] In the above embodiments, the first light-emitting surface and / or the second light-emitting surface may be provided with a frosted texture to increase the uniformity of the lighting effect. Furthermore, diffusing powder may be added to the injection molding materials of the first light guide 1221 and the second light guide 1222 to further increase the uniformity of the lighting effect.
[0069] In some embodiments, the housing 11 includes a dome-shaped structure that encloses an accommodating space in which the integrated control module 12 and the light guide assembly 122 are assembled. The dome-shaped structure can serve as a lamp cover, and the entire integrated control module 12 and the light guide assembly 122 are completely enclosed within the dome-shaped structure, resulting in a complete and simple appearance.
[0070] Furthermore, such as Figure 10 As shown, the second side 1212 of the circuit board 121 can face the opening 151 of the cover structure. A shielding structure 15 can be provided on the side of the opening 151 of the cover structure to encapsulate the near-field communication device 1. The shielding structure 15 can have an opening 151 that exposes the external interface 129, and the interface can realize communication and power supply connection with external devices. The shielding structure 15 can also have mounting holes 152, which can be threaded holes, through which the near-field communication device 1 can be assembled with the outside.
[0071] In some embodiments, the housing 11 may include a light-transmitting element 111 and a light-blocking element 112. The light-blocking element 112 is disposed inside the light-transmitting element 111 and has a light-transmitting hole 113 forming a light-transmitting portion, allowing light from the light source assembly 125 to pass through the light-transmitting hole 113 and the light-transmitting element 111. The light-transmitting element 111 may be made of transparent PMMA material. PMMA material has good surface hardness, providing wear-resistant surface protection for the entire lamp cover while achieving a crystal-clear surface appearance. The light-blocking element 112 may be made of solid-color plastic material to provide a light-blocking effect at locations other than the light-transmitting hole 113.
[0072] Among them, the light-transmitting component 111 and the light-blocking component 112 are formed into a whole by two-color injection molding. Through two injection molding processes, two different colors or materials of plastic are combined into a whole, which respectively satisfies the function, aesthetics and overall structural strength of the light-transmitting component 111 and the light-blocking component 112.
[0073] In some embodiments, the circuit board 121 includes a first side 1211 and a second side 1212 disposed opposite to each other. The integrated control module 12 further includes a distance sensing module 128, which is disposed on the first side 1211. The near-field communication module and the main control module are disposed on the second side 1212. This satisfies the function of the distance sensing module 128 while avoiding structural and functional interference between the distance sensing module and the near-field communication module and the main control module. The distance sensing module 128 may be a TOF (Time-of-Flight) sensor.
[0074] In some embodiments, the near-field communication module 126 includes a near-field communication tag and a near-field communication reader. The first interface of the near-field communication tag and the second interface of the near-field communication reader are respectively connected to the main control module. The near-field communication device 1 integrates complete NFC tag and reading functions. It can access any NFC function through the main control module 127 and can also be externally connected to a terminal device via the external interface 129, improving the functional integration and ease of use of the near-field communication device 1. The near-field communication tag can be an NFC tag chip, and the near-field communication reader can be an NFC reader chip. The NFC tag chip and the NFC reader chip are integrated into the near-field communication module.
[0075] The aforementioned near-field communication device 1 may further include a near-field communication excitation antenna 13 and a near-field communication main antenna 14, which are assembled inside the housing 11.
[0076] In the above embodiments, this application highly integrates and merges the related modules of NFC function and interactive lighting effects. The light-transmitting component 111 and the light-blocking component 112, which serve as the lampshade, are combined using a two-color injection molding process. Furthermore, the light guide scheme has been innovated and optimized, concentrating all the LEDs of the light source component 125 on a small-sized circuit board 121, thus achieving excellent interactive lighting effects. This high degree of integration and merging significantly reduces the complexity of the solution, substantially lowering the cost and failure rate of the entire NFC functional module.
[0077] This application further provides a terminal device, which includes a device body and the aforementioned near-field communication device 1.
[0078] The integrated control module 12 of the near-field communication device 1 includes a circuit board 121, a near-field communication module 126, a main control module 127, a light source assembly 125, and an external interface 129.
