Description

Near field communication device TECHNICAL FIELD

[0001] The present specification relates to the technical field of near field communication, and in particular to a near field communication device. BACKGROUND

[0002] Near Field Communication (NFC) is a short-range high-frequency radio technology that operates within a distance of 20 centimeters at a frequency of 13.56 MHz. It is evolved from the integration of contactless radio frequency identification (RFID) and interconnection technology, and provides a very safe and fast communication method for various electronic products. Therefore, it has been increasingly applied in the fields of payment, electronic ticketing, access control, mobile identity recognition, anti-counterfeiting and the like.

[0003] Under the near field communication interaction mode, induction needs to be performed through a near field communication antenna coil. Currently, a copper wire near field communication antenna is adopted and deployed inside a main body component. In actual application, the current near field communication antenna scheme may have a problem of affecting the interaction experience due to insufficient proximity of an inductive object or other electromagnetic interference inside the main body component.

[0004] Therefore, there is a need for a near field communication antenna scheme that helps improve the interaction experience.

[0028] Optionally, the main body component further comprises a control chip.

Due to the transparent characteristic of the nano silver wire (the traditional copper wire is opaque), even if the near field communication antenna coil is moved out of the main body component, it will not block the user's view (for example, it will not block the display screen included in the main body component), and the distance to the inductive object is relatively shortened and the distance to other electromagnetic devices possibly existing in the main body component is relatively lengthened. Therefore, the requirement for the close distance to the inductive object can be reduced, the influence of electromagnetic interference in the interior can be reduced, and in addition, the low resistivity characteristic of the nano silver wire helps to improve the signal quality and the sensitivity of the antenna. Based on these reasons, the near field communication interaction experience can be improved. BRIEF DESCRIPTION OF DRAWINGS

[0050] The embodiments of the present specification provide various near field communication devices.

[0051] In order for those skilled in the art to better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be described clearly and completely below in conjunction with the drawings in the embodiments of the present specification. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments of the present specification, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0052] For the near field communication scenario, the traditional near field communication copper wire antenna scheme is adopted. There are mainly the following three specific embodiments: one is to form a copper wire antenna coil by wiring on a flexible circuit board; one is to form a copper wire antenna coil by wiring on a hard circuit board; one is to form a copper wire antenna coil by winding or structure design on the metal structural part of the device.

[0053] The first two solutions have antennas deeply built-in, which are usually close to the electronic devices and are easily affected by internal electromagnetic interference, thereby reducing the performance of the antennas; the third solution is limited by the production process of the structural member, and the consistency of the DC impedance and inductance value of the antenna is poor, which can cause unstable performance of the antenna.

[0054] To solve the problems in the prior art, the application optimizes the traditional near-field communication copper wire antenna deeply built-in solution from multiple dimensions, mainly using the low resistivity and high transparency of nano silver wire to design a near-field communication antenna solution; the dimensions include improving the performance of the antenna, reducing the design limitations of the antenna on the product, etc.

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

[0056] FIG. 1 is a structural schematic diagram of a near-field communication device according to one or more embodiments of the present specification, which can be used in business scenarios such as near-field communication-based payment, check-in, etc.

[0057] Taking the payment scenario as an example, the near-field communication device can be a device on the merchant side (such as a desktop cash register, a handheld POS machine, etc.), or a device on the consumer side (such as a smartphone, a smartwatch, other wearable devices, a portable game console, etc.). Through the merchant device, the relevant business code value (such as a payment code, a check-in address, a payment amount, an electronic ticket, etc.) or other business information (such as discount information, advertisements, etc.) can be provided to the consumer device close to it through near-field communication interaction, so as to complete the target business; similarly, the relevant business information can also be provided by the consumer device to the merchant device in the reverse direction, so as to complete the target business.

[0058] The near-field communication device in FIG. 1 at least includes a main body component 102, a shell component 104, and a near-field communication antenna coil 106.

[0059] The main body component 102 is used to process or interact with near-field communication related business 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 component 102 can include a control chip and other components; for a near-field communication device that displays information to the user or interacts with the user through a screen, the main body component 102 can also include a display screen, etc. Generally, at least most of the relevant electromagnetic devices and components that need to be covered and protected belong to the main body component 102.

[0063] The control chip of the near field communication device can be one or more. In the case of multiple, a control architecture of overall control combined with multiple sub-controls can be adopted, or various more independent decentralized control architectures can be adopted.

[0064] The shell component 104 partially or entirely covers the main body component 102. For an inductive object (another near field communication enabled device or an IC card, etc.) approaching the near field communication device from the outside, the distance between the shell component 104 and the inductive object is closer than the distance between the main body component 102 and the inductive object; similarly, the near field communication device can also actively approach the inductive object, or both sides approach each other at the same time. Based on this, the near field communication antenna coil 106 is not disposed in the main body component 102, but is disposed between the main body component 102 and the shell component 104, preferably, especially can be disposed close to one side of the shell component 104, so that the near field communication antenna coil 106 can be as close as possible to the inductive object, facilitating more efficient and reliable induction.

[0065] It should be noted that the near field communication antenna coil 106 can also be embedded in the shell component 104, or disposed on the outer surface of the shell component 104, so that it is further closer to the inductive object. However, compared with being disposed between the main body component 102 and the shell component 104, the damage risk or the manufacturing cost can be increased.

[0066] The shell component 104 can be made of flexible material or hard material as needed. It generally contains one or more materials such as glass, plastic, and metal. In order to prevent the shielding signal from affecting the operation of the near field communication antenna coil 106, it is possible to avoid using metal materials entirely.

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

[0068] In terms of improving antenna performance, the low resistivity of the nano silver wire helps the near field communication antenna coil 106 to reduce signal loss during transmission, improve signal quality and antenna sensitivity. The high transparency of the nano silver wire enables the near field communication antenna coil 106 to be deployed on almost the entire surface of the electromagnetic insulating material without hindering the user's visual interaction, so that the antenna can be maximally close to the product surface, reducing the attenuation of the antenna performance with the increase of the working distance, and reducing the interference of the electromagnetic devices inside the product on the antenna performance.

[0069] In terms of reducing the design restrictions of the antenna on the product, the high transparency and flexibility of the nano silver wire enables the near field communication antenna coil 106 to be printed on the surface of many electromagnetic insulating materials, and the appearance design of the product can not consider the influence of the antenna on the appearance, thereby increasing the flexibility of the appearance design of the product.

[0070] The near field communication antenna coil 106 can specifically include one or more coils; in the case of multiple coils, it can also be specifically deployed as one or more groups of coils, and each group of coils can include one or more coils. According to actual needs, the near field communication antenna coil 106 can work as an active coil in the case of power supply, or work as a passive coil in the case of no power supply. In the case of power supply, the main component 102 can also include a corresponding power supply module.

[0071] Through the scheme in FIG. 1, the near field communication antenna coil made of nano silver wire instead of copper wire is adopted, and the position of the near field communication antenna coil is newly deployed compared with the traditional scheme by using the characteristics of the nano silver wire material, that is, the near field communication antenna coil is not deployed inside the main component but is moved out of the main component. Due to the transparent characteristic of the nano silver wire (the traditional copper wire is opaque), even if it is moved out of the main component, it will not block the user's line of sight (for example, it will not block the display screen included in the main component), and the distance to the sensing object is relatively shortened, and the distance to other electromagnetic devices that can exist inside the main component is relatively lengthened. Therefore, the requirement for the approaching distance of the sensing object can be reduced, the influence of the electromagnetic interference inside can be reduced, and in addition, the low resistivity characteristic of the nano silver wire also helps to improve the signal quality and the sensitivity of the antenna; based on these reasons, the near field communication interaction experience can be improved.

[0072] Based on the scheme in FIG. 1, this specification also provides some specific implementation schemes and extension schemes of the scheme, which will be described below.

[0073] In one or more embodiments of the specification, it is assumed that the sensing object is a mobile terminal such as a mobile phone, and the near field communication device is usually a stationary device (such as a cash register machine placed on a cash register, a sign-in machine fixed at a gate, 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, and for this case, the advantages of the scheme of the present application can be particularly embodied, and FIG. 2 is another structural schematic diagram of a near field communication device provided by one or more embodiments of the specification.

[0074] The near field communication device in FIG. 2 at least includes the display screen 1022, the transparent cover plate 1042, and the near field communication antenna coil 106 made of nano silver wires. The structure in FIG. 2 can be a specific implementation of the structure in FIG. 1. In terms of the association between the two structures, specifically, the main part 102 includes the display screen 1022, which is used to show information to the user and can optionally provide an interactive operation channel for the user; and the shell part 104 includes the transparent cover plate 1042, which is used to cover the display screen 1022. The material of the transparent cover plate 1022 can be glass, plastic, or the like.

[0075] Taking the smart phone as an example of the near field communication device, the display screen 1022 can be the inner screen of the smart phone, and the transparent cover plate 1042 can be the outer screen of the smart phone.

[0076] In one or more embodiments of the present specification, based on the flexible characteristics of the nano silver wires, the near field communication antenna coil can be printed on the inner surface of the shell part, so as to be as close as possible to the surface of the product and be closer to the inductive object. For example, in the case of the display screen 1022, the near field communication antenna coil 106 can be disposed on the inner surface of the transparent cover plate 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 the traditional copper coil cannot achieve such an effect.

[0077] In order to facilitate induction, the near field communication antenna coil 106 can be disposed on more areas of the inner surface of the transparent cover plate 1042. How to dispose specifically, the present application also considers the application scenarios of the display screen 1022, and tries to reduce the influence 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 plate 1042 and the display screen 1022, especially without considering the influence on the touch effect. Therefore, it can be more arbitrary to dispose, for example, the near field communication antenna coil 106 can be disposed in the middle area between the display screen 1022 and the transparent cover plate 1042. More intuitively, one or more embodiments of the present specification correspondingly provide a first specific structural diagram of the near field communication device, as shown in FIG. 3.

[0079] In FIG. 3, the transparent cover plate 1042 is specifically cover glass. The right side is a front view of the near field communication device (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 disposed on the inner surface of the cover glass (of course, it is also possible to be disposed on the outer surface of the display screen), and is located in the middle region of the screen. The coil is relatively small and concentrated for a small signal, and since it is actually highly transparent, it does not affect the display effect, and users tend to be closer to the middle region of the screen for interaction, so it is helpful for more efficient and reliable sensing.

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

[0081] In FIG. 4, the transparent cover plate 1042 is specifically cover glass. The right side is a front view of the near field communication device (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 disposed 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 operation, and helping to avoid affecting the touch effect.

[0082] The foregoing lists a regular flat shape (rectangular or square) display screen 1022, and in actual applications, a display screen 1022 of a special shape (for example, a convex circular shape, a convex elliptical shape, etc., which is considered as a special shape from the perspective of the screen) can also be used, and accordingly, the transparent cover plate is also correspondingly special-shaped. Similarly, even if the main body part 102 does not contain the display screen 1022, the shell part 104 can also adopt such a special-shaped structure. The special-shaped structure refers to a shape that is not commonly used from the perspective of itself (for example, as cover glass) or from the perspective of other components that cooperate with it (for example, for the display screen).

[0083] For the case that the shell part 104 is a profiled structure, the near field communication antenna coil 106 can be disposed on the inner surface of the profiled structure. Preferably, if the profiled structure is a non-flat structure (for example, at least partially outwardly convex or inwardly concave, etc.), the near field communication antenna coil 106 can be disposed on the inner surface of the region with a relatively higher outward convexity, so that the distance to the inductive object is relatively closer. More intuitively, one or more embodiments of the present specification correspondingly provide a third specific structural schematic diagram of the near field communication device, as shown in FIG. 5.

[0084] In FIG. 5, several different angles of the profiled structure are shown. It can be seen that the profiled structure is in the shape of a circular disc as a whole, the inner surface is outwardly convex, and the near field communication antenna coil 106 is exemplarily disposed on the edge region of the convex part of the inner surface (the convexity of which is already relatively high). This is a compromise between the concentration and universality of antenna induction. Of course, the near field communication antenna coil 106 can be closer to the central region of the convex part.

[0085] In one or more embodiments of the present specification, in order to further improve the induction capability of the near field communication antenna coil 106, it is considered to dispose the near field communication antenna coil 106 to a certain extent, while also wanting to avoid the near field communication antenna coil 106 from being worn. Based on such an idea, the inner surface of the shell part 104 can be provided with an outwardly open heat dissipation slot. Based on the flexible nature of nanosilver wires, and the fact that they can be printed and disposed with extremely thin thickness, at least a part of the near field communication antenna coil 106 can be disposed on the side wall of the heat dissipation slot, so as not to hinder the normal play of the heat dissipation capability, thereby achieving a positive effect in one fell swoop.

[0086] Similarly, for the above-mentioned scenario of the profiled structure, the inner surface of the profiled structure can be provided with an outwardly open heat dissipation slot at the outwardly convex part, and at least a part of the near field communication antenna coil 106 can be disposed on the side wall of the heat dissipation slot.

[0087] Based on the above several exemplary structural presentations, more deployment schemes can be derived, and the corresponding positive effects can also be achieved. The implementation and use can be carried out according to actual needs.

[0088] In one or more embodiments of the present specification, considering that folding screens are currently being applied more and more, folding screens can also be used on near field communication devices. In the scenario of folding screens, the near field communication device has at least two states of folding screen opening and folding, and the switching of the two forms may affect the signal of the near field communication antenna coil, especially the folding state which may have an adverse effect. In order to solve the problem of antenna signal in this scenario, for the near field communication device in FIG. 2, the display screen 1022 and the transparent cover plate 1042 can also constitute a folding screen supporting folding operation, and the shell component 104 further includes an outer cover plate (for example, the back plate of the folding screen mobile phone, it should be noted that there can be one or more additional screens on the outer cover plate to provide a user with a view in the folded state) facing away from the folding screen (here, referring to the front of the folding screen mobile phone in the open state, if folded, it will be folded to the inside); the near field communication device can further include: a near field communication additional antenna coil disposed on the outer surface or the inner surface of the outer cover plate. In this way, the near field communication device includes the above-mentioned two types of near field communication additional antenna coils and near field communication additional antenna coils, which can adapt to the folding screen state, select the appropriate antenna to achieve better results.

[0089] Based on such an idea, one or more embodiments of the present specification provide a flowchart of a near field communication antenna selection scheme in a folding screen scenario, as shown in FIG. 6.

[0090] In the scenario of FIG. 6, the main component 102 further includes a control chip for executing the flow. The flow in FIG. 6 includes the following steps S602 to S606.

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

[0092] S604: If yes, the near field communication additional antenna coil is used to perform near field communication with a nearby induction object to interact with service information.

[0093] In the folded state, the near field communication antenna coil 106 is further folded to the inside because it is disposed between the display screen 1022 and the transparent cover plate 1042, which may adversely affect the signal. In order to prevent this situation from affecting near field communication interaction, the near field communication additional antenna coil on the outer cover plate can be enabled to ensure signal quality.

[0094] Further, since the near field communication additional antenna coil is disposed relatively far enough outside, it can be relatively smaller, mainly for assistance, so as to help reduce costs and reduce the probability of wear and tear.

[0095] S606: Otherwise, near field communication is performed with the close induction object through the near field communication antenna coil to interact with the service information.

[0096] In the open state, the advantage of the near field communication antenna coil 106 can be fully played, so 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 comprises a control chip, a near field communication additional antenna coil, and a stylus wirelessly connected to the main body component 102; the near field communication additional antenna coil is disposed on the stylus; the control chip judges whether the stylus has established near field communication with the induction object of the near field communication device through the near field communication additional antenna coil; if so, the main body component does not establish near field communication with the induction object through the near field communication antenna coil, but indirectly interacts with the induction object through the stylus. The near field communication additional antenna coil can be made of nanosilver wire, which is flexible and extremely thin, and can be reliably deployed on a narrow entity such as a stylus. It can be disposed on the outer or inner surface of the stylus, and can also be disposed near the tip of the stylus, which helps to achieve precise positioning of near field communication and point-to-point connection.

[0098] Through this indirect communication mode, the user can use a light and handy stylus to approach the induction object (which can be fixed or mobile) to achieve near field communication service interaction between the near field communication device and the induction object, which is reliable and convenient to operate (the handheld stylus can be accurately pointed to the induction object for near field communication interaction), and the near field communication induction range is greatly expanded. Even in the case that the induction object also includes a stylus, both parties can be connected through the stylus to achieve near field communication between their respective rear devices.

[0099] The above is an example of deploying a near field communication antenna coil 106 made of nanosilver wire between the main body component 102 and the shell component 104. Based on the same idea, one or more embodiments of the present specification also provide another structural diagram of a near field communication device, as shown in FIG. 7.

[0100] The near field communication device in FIG. 7 comprises a main body component 102, a shell component 104, and a near field communication antenna coil 106.

[0101] The main body component 102 is used to process or interact with 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, which is arranged on the outer surface of the shell member 104 or embedded in the shell member 104. Thus, the distance between the near field communication antenna coil 106 and the inductive object can be further reduced, which helps to improve the near field communication efficiency and success rate.

[0104] More specific solutions can be implemented similarly as described above, which will not be repeated here.

[0105] In the 1990s, it was relatively easy to distinguish whether an improvement in a technology was a hardware improvement (e.g., an improvement in the circuit structure of a diode, transistor, switch, etc.) or a software improvement (an improvement in a method flow). However, as technology has evolved, many improvements in method flows today can be considered as direct improvements in hardware circuit structures. Designers almost always obtain the corresponding hardware circuit structures by programming the improved method flows into hardware circuits. Therefore, it cannot be said that an improvement in a method flow cannot be implemented using hardware entity modules. For example, a programmable logic device (PLD) (e.g., a field programmable gate array (FPGA)) is an integrated circuit whose logic function is determined by user programming of the device. A digital system is "integrated" on a PLD by the designer programming the PLD, rather than by ordering a chip manufacturer to design and fabricate a custom integrated circuit chip. Moreover, instead of manually fabricating integrated circuit chips, this programming is now mostly implemented using "logic compiler" software, which is similar to software compilers used in program development, and the original code to be compiled is written in a specific programming language, which is called a hardware description language (HDL), and there are many such languages, 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., and the most commonly used are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should be aware that, as long as the method flow is logically programmed using the above-mentioned hardware description languages and programmed into an integrated circuit, a hardware circuit implementing the logical method flow can be easily obtained.

[0106] The controller can be implemented in any suitable way, for example, the controller can take the form of a microprocessor or processor and a computer readable medium storing computer readable program code, such as software or firmware, executable by the (micro)processor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller and an embedded microcontroller, examples of which 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. Those skilled in the art will also know that, in addition to being implemented in pure computer readable program code, the controller can also be implemented to perform the same functions in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers and embedded microcontrollers, etc. by logically programming the method steps. Therefore, such a controller can be considered as a hardware component, and the means included therein for implementing various functions can also be considered as structures within the hardware component.
