The full text of the application is incorporated into this application by reference. Technical Field

[0002] The present invention relates to the field of near field communication technology, and in particular to near field communication equipment. Background Art

[0003] Near Field Communication (NFC) is a short-range high-frequency radio technology that operates at a frequency of 13.56MHz within a distance of 20cm. It is an integration of contactless radio frequency identification (RFID) and interconnection technology, providing a very safe and fast communication method for various electronic products. Therefore, it has been increasingly used in payment, electronic ticketing, access control, mobile identity recognition, anti-counterfeiting and other business fields.

[0004] In the near-field communication interaction mode, induction is required through the near-field communication antenna coil. Currently, the copper wire near-field communication antenna is deployed inside the main body of the near-field communication device. In actual applications, the currently used near-field communication antenna solution may have problems affecting the interactive experience due to insufficient proximity of the sensing object or other electromagnetic interference inside the main body.

[0005] Based on this, a near field communication antenna solution is needed that helps to improve the interactive experience. Summary of the invention

[0027] The additional antenna coil for near field communication is disposed on the outer surface or the inner surface of the outer cover plate.

[0028] Optionally, the main body component further includes a control chip;

Instead of deploying it inside the main body component, it is moved out of the main body component; due to the transparent characteristics of the nano-silver wire (traditional copper wire is opaque), even if it is moved out of the main body component, it will not block the user's line of sight (for example, it will not block the display screen included in the main body component), and the distance to the sensing object becomes relatively closer, and the distance to other electromagnetic devices that may exist inside the main body component becomes relatively farther, therefore, the requirement for the proximity distance of the sensing object can be reduced, and the influence of internal electromagnetic interference can be reduced. Moreover, the low resistivity characteristics of the nano-silver wire also help to improve the signal quality and the sensitivity of the antenna; for these reasons, it helps to improve the near-field communication interactive experience.

[0050] The embodiments of this specification provide a variety of near field communication devices.

[0051] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0052] For near-field communication scenarios, the traditional near-field communication copper wire antenna solution is adopted. There are mainly three specific implementation methods: one is to form a copper wire antenna coil by routing on a flexible circuit board; one is to form a copper wire antenna coil by routing on a hard circuit board; and one is to form a copper wire antenna coil on the metal structure of the device by winding or structural design.

[0053] In the first two solutions, the antennas are deeply built-in, usually close to electronic devices, and are easily affected by internal electromagnetic interference, thereby reducing antenna performance. The third solution is limited by the production process of structural parts, and the DC impedance and inductance values ​​of the antenna are poorly consistent, which will lead to unstable antenna performance.

[0054] In response to these problems in the prior art, this application has made design optimizations to the traditional near-field communication copper wire antenna deep-embedded solution from multiple dimensions, mainly utilizing the two characteristics of low resistivity and high transparency of nano silver wire to design the near-field communication antenna solution; the dimensions include: improving antenna performance, reducing antenna restrictions on product design, etc.

[0055] Based on this general idea, the solution of this application will be further described below.

[0056] Figure 1 A schematic diagram of the structure of a near field communication device provided in one or more embodiments of this specification. The near field communication device can be used in business scenarios such as payment and check-in based on near field communication.

[0057] Taking the payment scenario as an example, the NFC device can be a device on the merchant side (e.g., desktop cash registers, handheld POS machines, etc.) or a device on the consumer side (e.g., smartphones, smart watches, other wearable devices, portable game consoles, etc.). Through the merchant device, the relevant business code value (e.g., payment code, check-in address, payment amount, electronic tickets, etc.) or other business information (e.g., discount information, advertisements, etc.) can be provided to the nearby consumer device through the NFC interaction method to complete the target business; similarly, the consumer device can also provide relevant business information to the merchant device in reverse to complete the target business.

[0058] Figure 1 The near field communication device comprises at least a main body component 102, a housing component 104, and a near field communication antenna coil 106;

[0059] The main component 102 is used to process or exchange near field communication related service information;

[0060] The shell component 104 covers the main body component 102;

[0061] The near field communication antenna coil 106 is made of nano silver wire and is disposed between the main body component 102 and the shell component 104 .

[0062] The main body 102 may include components such as a control chip; for a near field communication device that displays information to a user or performs interactive operations through a screen, the main body 102 may also include a display screen, etc. Generally, at least most of the related electromagnetic devices and components that need to be covered and protected belong to the main body 102.

[0063] There may be one or more control chips for the near field communication device. In the case of multiple control chips, a control architecture of a master control combined with multiple sub-controls may be adopted, or various more independent decentralized control architectures may be adopted.

[0064] The shell component 104 partially or completely covers the main body component 102. For a sensing object (other devices supporting near field communication or IC cards, etc.) approaching the near field communication device from the outside, the distance between the shell component 104 and the sensing object is closer than the distance between the main body component 102 and the sensing object; similarly, the near field communication device may actively approach the sensing object, or both parties may approach each other at the same time. Based on this, the present application deploys the near field communication antenna coil 106 not in the main body component 102, but between the main body component 102 and the shell component 104. Preferably, it can be deployed on the side close to the shell component 104. In this way, the near field communication antenna coil 106 can be as close to the sensing object as possible, so as to facilitate more efficient and reliable sensing.

[0065] It should be noted that the near field communication antenna coil 106 can also be buried in the housing component 104, or deployed on the outer surface of the housing component 104, so as to be closer to the sensing object. However, compared with deploying between the main component 102 and the housing component 104, these two methods may increase the risk of damage or the manufacturing cost.

[0066] The housing component 104 may be made of either flexible material or hard material as required, generally including one or more materials of glass, plastic, and metal. In order to prevent shielding signals from affecting the operation of the near field communication antenna coil 106, it is possible to avoid using all metal materials.

[0067] The near field communication antenna coil 106 is not made of traditional copper wire, but is made of nano silver wire, which has at least the characteristics of low resistivity, high transparency and flexibility.

[0068] In terms of improving antenna performance. The low resistivity of nano silver wires is used to help the near field communication antenna coil 106 reduce signal loss during transmission, thereby improving signal quality and antenna sensitivity. The high transparency of nano silver wires allows the near field communication antenna coil 106 to be deployed on almost all areas of the surface of electromagnetically insulating materials without causing obstacles to the user's visual interaction, thereby allowing the antenna to be as close to the product surface as possible, reducing the attenuation of antenna performance as the working distance increases, and reducing the interference of electromagnetic devices inside the product on the antenna performance.

[0069] In terms of reducing the restrictions of antenna on product design, by utilizing the high transparency and flexibility of nano silver wires, the near field communication antenna coil 106 can be printed on the surface of many electromagnetic insulating materials, and the impact of the antenna on the appearance of the product can be ignored when designing the appearance, thereby increasing the flexibility of product appearance design.

[0070] The near field communication antenna coil 106 may specifically include one or more coils; in the case of multiple coils, it may also be specifically deployed as one or more groups of coils, each group of coils may include one or more coils. According to actual needs, the near field communication antenna coil 106 may work as an active coil when powered, or as a passive coil when not powered. In the case of power supply, the main body 102 may also include a corresponding power supply module.

[0071] pass Figure 1 The solution in the embodiment adopts a near-field communication antenna coil made of nano-silver wire instead of copper wire, and utilizes the characteristics of the nano-silver wire material to deploy the near-field communication antenna coil in a new position compared with the traditional solution. Instead of deploying it inside the main part, it is moved out of the main part. Due to the transparent characteristics of the nano-silver wire (traditional copper wire is opaque), even if it is moved out of the main part, it will not block the user's line of sight (for example, it will not block the display screen included in the main part), and the distance to the sensing object becomes relatively closer, and the distance to other electromagnetic devices that may exist inside the main part becomes relatively farther. Therefore, the requirement for the proximity of the sensing object can be reduced, and the influence of internal electromagnetic interference can be reduced. In addition, the low resistivity characteristics of the nano-silver wire also help to improve the signal quality and the sensitivity of the antenna. For these reasons, it helps to improve the near-field communication interactive experience.

[0072] based on Figure 1 This specification also provides some specific implementation plans and extension plans of the scheme, which will be described below.

[0073] In one or more embodiments of this specification, it is assumed that the sensing object is a user mobile terminal such as a mobile phone, and the near-field communication device is usually a stationary device (for example, a cash register placed on a cash register counter, a check-in machine fixed at a door access control, etc.), and the user mobile terminal actively approaches the near-field communication device. In order to facilitate more intuitive interaction and prompt the user, the near-field communication device can provide a display screen. In this case, the advantages of the present application solution can be particularly reflected. Figure 2 Another structural schematic diagram of a near field communication device provided in one or more embodiments of this specification.

[0074] Figure 2 The near field communication device at least comprises a display screen 1022, a transparent cover plate 1042, and a near field communication antenna coil 106 made of nano silver wires. Figure 2 The structure in can be Figure 1 In terms of the relationship between the two structures, specifically, the main body component 102 includes a display screen 1022 for displaying information to the user and optionally providing an interactive operation channel for the user; the shell component 104 includes a transparent cover 1042 for covering the display screen 1022. The material of the transparent cover 1042 can be glass, plastic, etc.

[0075] Taking a near field communication device such as a smartphone as an example, the display screen 1022 may be an inner screen of the smartphone, and the transparent cover 1042 may be an outer screen of the smartphone.

[0076] In one or more embodiments of the present specification, based on the flexible characteristics of nano silver wires, the near field communication antenna coil can be printed on the inner surface of the housing component, so that it can be as close to the product surface as possible and closer to the sensing object. For example, in the case of a display screen 1022, the near field communication antenna coil 106 can be deployed on the inner surface of the transparent cover 1042. Since the near field communication antenna coil 106 is highly transparent, it will not affect the user's viewing of the content displayed on the display screen 1022, while traditional copper wire coils cannot achieve such an effect.

[0077] For the convenience of sensing, the near field communication antenna coil 106 can be deployed on more areas on the inner surface of the transparent cover 1042. As for the specific deployment, the present application also considers the application scenarios of the display screen 1022 to minimize the impact on different application scenarios.

[0078] For example, in one application scenario, the display screen 1022 does not support touch operation. In this case, the near-field communication antenna coil 106 has little effect on the transparent cover 1042 and the display screen 1022, and there is no need to consider the possible impact on the touch effect. Therefore, it can be deployed more arbitrarily, for example, the near-field communication antenna coil 106 can be deployed in the middle area between the display screen 1022 and the transparent cover 1042. More intuitively, one or more embodiments of this specification provide a first specific structural diagram of a near-field communication device, see Figure 3 .

[0079] exist Figure 3 In the figure, the transparent cover plate 1042 is specifically a cover glass. The right side is a front view of the near-field communication device (which may be a partial front view), and the left side is a more intuitive corresponding exploded view. It can be seen that the near-field communication coil is deployed on the inner surface of the cover glass (of course, it can also be deployed on the outer surface of the display screen), and is located in the middle area of ​​the screen. The coil is more concentrated with relatively small signals. Since it is actually highly transparent, it does not affect the display effect, and users tend to interact closer to the middle area of ​​the screen, which helps to sense more efficiently and reliably.

[0080] In another application scenario, the display screen 1022 supports touch operation. In this case, the near field communication antenna coil 106 may affect the touch effect of the transparent cover 1042 and the display screen 1022. Therefore, the near field communication antenna coil 106 can be deployed as much as possible in an area where the user does not often perform touch interaction, for example, deployed in the surrounding area between the display screen 1022 and the transparent cover 1042. More intuitively, one or more embodiments of this specification provide a second specific structural schematic diagram of a near field communication device, see Figure 4 .

[0081] exist Figure 4 In the figure, the transparent cover plate 1042 is specifically a cover glass. The right side is a front view of the near field communication device (which may be a partial front view), and the left side is a more intuitive corresponding exploded view. It can be seen that the near field communication coil is deployed on the inner surface of the cover glass, and is located in the surrounding area of ​​the display screen, avoiding the area where the user is more likely to perform touch operations, which helps to avoid affecting the touch effect.

[0082] The above examples are conventional flat-shaped (rectangular or square) display screens 1022. In actual applications, it is also possible to use display screens 1022 with special shapes (for example, raised circles, raised ovals, etc., here we consider whether it is considered to be a special shape from the perspective of the screen), and accordingly, its transparent cover is also correspondingly special-shaped. Similarly, even if the main body 102 does not include the display screen 1022, the outer shell 104 may also use such a special-shaped structural member. Special-shaped structural members refer to structures that are not commonly used in terms of shape from the perspective of themselves (for example, as a cover glass) or from the perspective of other components that cooperate with them (for example, for the display screen).

[0083] In the case where the housing component 104 is a special-shaped structural component, the near-field communication antenna coil 106 can be deployed on the inner surface of the special-shaped structural component. Preferably, if the special-shaped structural component is a non-flat structural component (for example, at least part of the area is convex outward or concave inward, etc.), it can be deployed in an area on the inner surface that is relatively more convex outward (pointing to the outside of the near-field communication device), so that the distance sensing object is relatively closer. More intuitively, one or more embodiments of this specification provide a third specific structural schematic diagram of a near-field communication device, see Figure 5 .

[0084] exist Figure 5 In FIG. 1 , several different angles of the special-shaped structural member are shown. It can be seen that the special-shaped structural member is in the shape of a circular disc as a whole, and the inner surface is convex outward. The near-field communication antenna coil 106 is exemplarily deployed at the edge area of ​​the convex part on the inner surface (the convexity here is already high), which takes into account the concentration and extensiveness of the antenna induction. Of course, the near-field communication antenna coil 106 can also be closer to the central area of ​​the convex part.

[0085] In one or more embodiments of the present specification, in order to further improve the inductive capability of the near field communication antenna coil 106, it is considered to openly deploy the near field communication antenna coil 106 to a certain extent, while at the same time wanting to avoid wear of the near field communication antenna coil 106. Based on this idea, a heat dissipation slit open to the outside can be provided on the inner surface of the housing component 104. Based on the flexibility of the nano silver wire and the ability to be printed and deployed with an extremely thin thickness, at least most of the near field communication antenna coil 106 can be deployed on the side wall of the heat dissipation slit, so that the normal performance of the heat dissipation capability will not be hindered, achieving a positive effect of killing two birds with one stone.

[0086] Similarly, for the scenario of the special-shaped structural member mentioned above, an outwardly open heat dissipation slot may be provided at the outwardly protruding portion on the inner surface of the special-shaped structural member, and at least a majority of the near field communication antenna coil 106 may be deployed on the side wall of the heat dissipation slot.

[0087] Based on the above exemplary structural presentations, more deployment schemes can be derived, which may also achieve corresponding positive effects and can be implemented and used according to actual needs.

[0088] In one or more embodiments of this specification, considering that foldable screens are now increasingly used, foldable screens can also be used on near-field communication devices. In the foldable screen scenario, the near-field communication device has at least two states: the foldable screen is open and folded. The switching between these two states may affect the signal of the near-field communication antenna coil, especially the folded state may have an adverse effect. In order to solve the antenna signal problem in this scenario, for Figure 2 The near-field communication device in the display screen 1022 and the transparent cover plate 1042 can also constitute a folding screen that supports folding operation. The shell component 104 also includes an outer cover plate (for example, the back plate of a folding screen mobile phone. It should be noted that there may also be one or more additional screens on the outer cover plate for users to watch in the folded state) facing away from the folding screen (here, it refers to the front of the folding screen mobile phone in the open state, which will be retracted to the inside if folded). The near-field communication device can also include: a near-field communication additional antenna coil, which is deployed on the outer surface or inner surface of the outer cover plate. In this way, the near-field communication device includes the above-mentioned two types of antennas, the near-field communication additional antenna coil and the near-field communication additional antenna coil, which can adapt to the folding screen state and select a suitable antenna to achieve better results.

[0089] Based on this idea, one or more embodiments of this specification provide a flowchart of a near-field communication antenna selection solution in a folding screen scenario, see Figure 6 .

[0090] exist Figure 6 In the scenario, the main component 104 also includes a control chip for executing the process. Figure 6 The process in includes the following steps:

[0091] S602: The control chip detects whether the folding screen is in a folded state.

[0092] S604: If yes, perform near field communication with a nearby sensing object through the near field communication additional antenna coil to exchange business information.

[0093] In the folded state, the NFC antenna coil 106 is disposed between the display screen 1022 and the transparent cover plate 1042, and therefore is further folded inward, which may have an adverse effect on the signal. In order to prevent this from affecting the NFC interaction, the NFC additional antenna coil on the outer cover plate can be enabled to ensure the signal quality.

[0094] Furthermore, since the additional antenna coil for near field communication is deployed relatively far enough outward, it can be made relatively smaller and mainly used for auxiliary purposes, which helps to reduce costs and also reduces the probability of wear.

[0095] S606: Otherwise, near field communication is performed with a nearby sensing object through the near field communication antenna coil to exchange service information.

[0096] In the open state, the advantages of the near field communication antenna coil 106 can be fully utilized, and therefore, the near field communication antenna coil 106 can be used preferentially.

[0097] In one or more embodiments of the present specification, the near field communication device further includes a control chip, a near field communication additional antenna coil, and a stylus wirelessly connected to the main body 102; the near field communication additional antenna coil is deployed on the stylus; the control chip determines whether the stylus has established near field communication with the sensing object of the near field communication device through the near field communication additional antenna coil; if so, the main body does not establish near field communication with the sensing object through the near field communication antenna coil, but indirectly interacts with the sensing object through the stylus. The near field communication additional antenna coil can be made of nano silver wire. Based on its flexible and extremely thin characteristics, it is easy to deploy more reliably on a narrow entity such as a stylus. It can be deployed on the outer surface or inner surface of the stylus, and in particular, it can be considered to be deployed in the area near the tip of the stylus, which helps to achieve accurate positioning of near field communication, and connect wherever you point.

[0098] Through this indirect communication method, the user can use a lightweight and handy stylus to get close to the sensing object (which can be fixed or mobile) to realize near-field communication service interaction between the near-field communication device and the sensing object. It has good reliability and convenient operation (the handheld stylus can be accurately pointed at the sensing object with which near-field communication interaction is desired), and it is equivalent to greatly expanding the near-field communication sensing range. Even when the sensing object also includes the stylus, both parties can achieve docking through the stylus to realize near-field communication between the devices behind each other.

[0099] The above is an example of deploying a near field communication antenna coil 106 made of nano silver wire between the main body 102 and the shell 104. Based on the same idea, one or more embodiments of this specification also provide a structural diagram of another near field communication device, see Figure 7 .

[0100] Figure 7 The near field communication device comprises a main body component 102, a housing component 104, and a near field communication antenna coil 106;

[0101] The main component 102 is used to process or exchange near field communication related service information;

[0102] The shell component 104 covers the main body component;

[0103] The near field communication antenna coil 106 is made of nano silver wire and is disposed on the outer surface of the housing component 104 or buried in the housing component 104. This can further reduce the distance between the near field communication antenna coil 106 and the sensing object, which helps to improve the efficiency and success rate of near field communication.

[0104] A more specific solution can be implemented similarly with reference to the above description, which will not be described in detail here.

[0105] In the 1990s, improvements to a technology could be clearly distinguished as hardware improvements (for example, improvements to the circuit structure of diodes, transistors, switches, etc.) or software improvements (improvements to the method flow). However, with the development of technology, many improvements to the method flow today can be regarded as direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that an improvement in a method flow cannot be implemented using a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the user's programming of the device. Designers can "integrate" a digital system on a PLD by programming it themselves, without having to ask a chip manufacturer to design and produce a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used when developing and writing programs, and the original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL). There is not only one HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also know that it is only necessary to program the method flow slightly in the above-mentioned hardware description languages ​​and program it into the integrated circuit, and then it is easy to obtain the hardware circuit that implements the logic method flow.

[0106] The controller can be implemented in any appropriate manner, for example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing a computer-readable program code (such as software or firmware) that can be executed by the (micro)processor, a logic gate, a switch, an application-specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory.
