Detailed Description

The present description provides various near field communication devices.

In order to make the technical solutions in the present specification better understood by those skilled in the art, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.

For near field communication, a near field communication copper wire antenna scheme is adopted conventionally. The method mainly comprises the following three specific embodiments: one is to form a copper wire antenna coil by running it on a flexible circuit board; one is to form a copper wire antenna coil on a hard circuit board by routing; one is to form a copper wire antenna coil on a metallic structural member of the device by wire winding or structural design.

The antenna of the former two schemes is deeply built-in, is usually close to an electronic device, and is easy to receive internal electromagnetic interference, so that the performance of the antenna is reduced; the third scheme is limited by the limitation of the production process of the structural part, and the poor consistency of the direct current impedance and the inductance value of the antenna can lead to unstable antenna performance.

Aiming at the problems in the prior art, the application designs and optimizes the scheme of deep built-in of the traditional near field communication copper wire antenna from multiple dimensions, and mainly designs the near field communication antenna scheme by utilizing the characteristics of low resistivity and high transparency of the nano silver wire; the dimensions include: improving the antenna performance, reducing the design limit of the antenna to the product, and the like.

The following is a description of the solution of the application based on such general idea.

Fig. 1 is a schematic structural diagram of a near field communication device provided in one or more embodiments of the present disclosure, where the near field communication device may be used in a business scenario such as payment, check-in, etc. based on near field communication.

Taking a payment scenario as an example, the near field communication device may be a merchant-side device (e.g., a desktop cash register, a handheld POS device, etc.), or a consumer-side device (e.g., a smart phone, a smart watch, other wearable device, a portable game device, etc.). Through merchant equipment, the relevant business code values (such as a cash register, a check-in address, a payment amount, an electronic ticket and the like) or other business information (such as preferential information, advertisements and the like) can be provided for the near consumer equipment through an interaction mode of near field communication so as to complete target business; similarly, relevant business information may also be provided by the consumer device to the merchant device in reverse in order to complete the targeted business.

The near field communication device in fig. 1 comprises at least a body part 102, a housing part 104, a near field communication antenna coil 106;

The main body part 102 is configured to process or interact with near field communication related service information;

the housing part 104 covering the body part 102;

the near field communication antenna coil 106 is made of nano silver wire and is disposed between the main body part 102 and the housing part 104.

The body part 102 may include a control chip or the like; for near field communication devices that display information to a user or interact with through a screen, the body component 102 may also include a display screen or the like. Generally, at least most of the relevant electromagnetic devices and parts that require shielding protection belong to the body part 102.

The control chip of the near field communication device may have one or more. In the case of multiple control architectures, a control architecture combining a plurality of sub-controls may be used, or various more independent decentralized control architectures may be used.

The housing member 104 partially or fully covers the body member 102. For an inductive object (other device supporting near field communication or IC card, etc.) that is close to the near field communication device from the outside, the distance between the housing part 104 and the inductive object is closer than the distance between the body part 102 and the inductive object; similarly, the near field communication device may be actively approaching the sensing object, or both may be approaching the sensing object at the same time. Based on this, the near field communication antenna coil 106 is disposed between the main body 102 and the housing 104 instead of being disposed in the main body 102, preferably, may be disposed near the housing 104, so that the near field communication antenna coil 106 is located as close to the sensing object as possible, which is convenient for sensing more efficiently and reliably.

The near field communication antenna coil 106 may be buried in the housing member 104 or disposed on the outer surface of the housing member 104, and thus, may be further located near the induction target. However, both of these approaches may increase risk of damage or manufacturing costs as compared to being disposed between the body member 102 and the housing member 104.

The housing member 104 may be made of a flexible material or a hard material as desired. Typically comprising one or more of glass, plastic, metal, all of which may be avoided in order to prevent the shield signal from affecting the operation of the near field communication antenna coil 106.

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

In terms of improving antenna performance. The low resistivity characteristic of the nano silver wire is utilized to help the near field communication antenna coil 106 reduce signal loss in the transmission process, and the signal quality and the sensitivity of the antenna are improved. By utilizing the high transparency characteristic of the nano silver wire, the near field communication antenna coil 106 can be deployed in almost all areas of the surface of the electromagnetic insulating material without causing barriers to visual interaction of users, so that the antenna can be maximally close to the surface of a product, the attenuation of the antenna performance which is increased along with the working distance is reduced, and meanwhile, the interference of electromagnetic devices inside the product on the antenna performance is reduced.

In terms of reducing the design constraints of the antenna on the product. By utilizing the high transparency and flexibility of the nano silver wire, the near field communication antenna coil 106 can be printed on the surface of a plurality of electromagnetic insulating materials, and the influence of the antenna on the appearance can be not considered when the product appearance is designed, so that the flexibility of the product appearance design is improved.

Near field communication antenna coil 106 may include, in particular, one or more coils; in the case of multiple coils, one or more groups of coils may also be specifically deployed, and each group of coils may include one or more coils therein. According to practical needs, the near field communication antenna coil 106 can work as an active coil under the condition of power supply, and can also work as a passive coil under the condition of no power supply. In the case of powered, the body member 102 may also include a corresponding power module for the case of powered.

By the scheme in fig. 1, the near field communication antenna coil made of the nano silver wire instead of the copper wire is adopted, and the characteristic of the nano silver wire material is utilized, compared with the traditional scheme, the near field communication antenna coil is completely deployed at a position, which is not deployed inside the main body part, but is shifted out of the main body part; because the transparent characteristic of the nano silver wire (the traditional copper wire is opaque), even if the main body part is moved out, the sight of a user is not blocked (for example, the display screen included in the main body part is not blocked), and the distance from an induction object is relatively close, and other electromagnetic devices possibly existing in the main body part are relatively far away, so that the requirement on the approach distance of the induction object can be reduced, the influence of electromagnetic interference in the main body part can be reduced, and besides, the low resistivity characteristic of the nano silver wire is beneficial to improving the signal quality and the sensitivity of an antenna; for these reasons, it is helpful to enhance the near field communication interaction experience.

The present specification also provides some specific embodiments and extensions of the scheme based on the scheme of fig. 1, and the following description is continued.

In one or more embodiments of the present disclosure, assuming that the sensing object is a user mobile terminal such as a mobile phone, the near field communication device is typically a device that is used by standing (e.g., a cash register placed on a cash register, a check-in machine fixed at a door access, etc.), and the user mobile terminal is actively approaching the near field communication device. In order to facilitate more intuitive interaction and prompt to a user, the near field communication device may provide a display screen, and for this case, the advantage of the solution of the present application may be particularly represented, and fig. 2 is another schematic diagram of the near field communication device provided in one or more embodiments of the present specification.

The near field communication device in fig. 2 at least includes a display screen 1022, a transparent cover 1042, and a near field communication antenna coil 106 made of nano silver wires, and the structure in fig. 2 may be a specific embodiment of the structure in fig. 1. In terms of the association relationship between the two structures, specifically, the main body part 102 includes a display screen 1022 for displaying information to the user, and optionally may provide an interactive operation channel for the user; the housing part 104 described above includes a transparent cover plate 1042 for covering the display screen 1022. The transparent cover 1042 may be made of glass, plastic, or the like.

Taking a near field communication device such as a smart phone as an example, the display screen 1022 may be an inner screen of the smart phone, and the transparent cover plate 1042 may be an outer screen of the smart phone.

In one or more embodiments of the present disclosure, the near field communication antenna coil may be printed on the inner surface of the housing member based on the flexible nature of the nano-silver wire, so that it can be as close to the product surface as possible, closer to the sensing object. For example, in the case of the display screen 1022, the near field communication antenna coil 106 may be disposed on the inner surface of the transparent cover plate 1042, and since the near field communication antenna coil 106 is highly transparent, it will not affect the user to watch the content displayed on the display screen 1022, but the conventional copper wire coil cannot achieve such effect.

To facilitate sensing, the near field communication antenna coil 106 may be disposed over more area on the inner surface of the transparent cover plate 1042. In particular, how to deploy, the application also considers the application scene of the display screen 1022, and reduces the influence on different application scenes as much as possible.

For example, in an application scenario where the display screen 1022 does not support touch operations, the influence of the near field communication antenna coil 106 on the transparent cover 1042 and the display screen 1022 is small, especially without considering the influence that may be brought about on the touch effect. Thus, the near field communication antenna coil 106 may be disposed more optionally, for example, in an intermediate region between the display screen 1022 and the transparent cover plate 1042, and more intuitively, one or more embodiments of the present disclosure correspondingly provide a first specific structural schematic of the near field communication device, see fig. 3.

In fig. 3, the transparent cover 1042 is specifically cover glass. The right side is a front view of the near field communication device (which may be part of the front side) 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 dispose it on the outer surface of the display screen), the location is in the middle region of the screen, the relatively small signals of the coil are more concentrated, the display effect is not affected because it is actually highly transparent, and the user tends to get closer to the interaction towards the middle region of the screen, thus contributing to a more efficient and reliable sensing.

In another application scenario, the display screen 1022 supports touch operation, in which case the near field communication antenna coil 106 may affect the touch effect of the transparent cover 1042 in cooperation with the display screen 1022. Therefore, the near field communication antenna coil 106 may be disposed as much as possible in an area where the user does not perform touch interaction, for example, in a surrounding area between the display screen 1022 and the transparent cover 1042, and more intuitively, one or more embodiments of the present disclosure correspondingly provide a second specific structural schematic diagram of the near field communication device, see fig. 4.

In fig. 4, the transparent cover 1042 is specifically cover glass. The right side is a front view of the near field communication device (which may be part of the front side) 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 the position is located in the surrounding area of the display screen, so that the area where the user is more likely to perform touch operation is avoided, and the influence on the touch effect is avoided.

The foregoing list is a conventional flat (rectangular or square) display screen 1022, and in practical applications, it is also possible to use a shaped (e.g., convex circular, convex elliptical, etc., where it is considered shaped from a screen perspective) display screen 1022, and correspondingly, the transparent cover plate is shaped accordingly. Similarly, even though the body member 102 does not include a display screen 1022, the housing member 104 may employ such shaped structures as well. Profiled structural members refer to shaped structures that are less commonly used from the perspective of themselves (e.g., as cover glass) or from the perspective of other components that mate with them (e.g., for display screens).

In the case where the housing component 104 is a profiled structure, the near field communication antenna coil 106 may be disposed on an inner surface of the profiled structure. Preferably, if the profiled structural member is a non-planar (e.g., at least a portion of the region is convex outward or concave inward, etc.), the profiled structural member may be disposed in a region of the inner surface that is relatively more convex outward (toward the outside of the near field communication device) and thus relatively closer to the sensing object. More intuitively, one or more embodiments of the present disclosure provide a third specific structural schematic diagram of a near field communication device, see fig. 5.

In fig. 5, several different angles of the profiled structure are shown, and it can be seen that the profiled structure is in the shape of a circular disc as a whole, the inner surface is convex outwards, and the near field communication antenna coil 106 is exemplarily disposed in the edge area of the convex part on the inner surface (the convex degree is high here), which is to consider both the concentration and the universality of the antenna induction. Of course, the near field communication antenna coil 106 may also be closer to the central region of the boss.

In one or more embodiments of the present description, to further enhance the inductive capacity of the near field communication antenna coil 106, it is contemplated that the near field communication antenna coil 106 may be deployed somewhat open while at the same time avoiding wear on the near field communication antenna coil 106. Based on such a concept, the heat dissipation slits open to the outside may be provided on the inner surface of the housing part 104, and based on the flexibility characteristics of the nano silver wire, the thickness of the printed arrangement may be extremely thin, so that at least a large part of the near-field communication antenna coil 106 may be arranged on the side wall of the heat dissipation slits, thereby not impeding the normal exertion of the heat dissipation capability, and having a multi-purpose positive effect.

Similarly, for the scenario of the above-mentioned profiled structure, the outwardly protruding portion on the inner surface of the profiled structure may be provided with outwardly open heat dissipation slits, and the near field communication antenna coil 106 may be disposed at least mostly on the side walls of the heat dissipation slits.

Based on the above several exemplary structural representations, further deployment schemes can also be derived, and corresponding positive effects are also possible, which can be implemented and used according to actual needs.

In one or more embodiments of the present disclosure, considering that the folding screen is used more and more currently, the folding screen may also be used on the near field communication device, where the near field communication device has at least two states of folding screen open and folding, and the switching of these two states may affect the signal of the near field communication antenna coil, and especially the folding state may have an adverse effect. To solve the antenna signal problem in this scenario, for the near field communication device in fig. 2, the display screen 1022 and the transparent cover 1042 may further form a folding screen supporting the folding operation, and the housing part 104 further includes an outer cover (for example, a back plate of the folding screen mobile phone, it should be noted that there may be one or more additional screens on the outer cover) opposite to the folding screen (here, the front surface of the folding screen mobile phone in the unfolded state, and the folding screen mobile phone may be folded to the inner side if folding) so as to be convenient for the user to watch in the folded state); the near field communication device may further include: near field communication additional antenna coils are arranged on the outer surface or the inner surface of the outer cover plate. Therefore, the near field communication equipment comprises the near field communication additional antenna coil and the near field communication additional antenna coil, and can be suitable for a folding screen state, and an appropriate antenna is selected to obtain a better effect.

Based on such a concept, one or more embodiments of the present disclosure provide a flow diagram of a near field communication antenna selection scheme in a folded screen scenario, see fig. 6.

In the scenario of fig. 6, the body component 104 also includes a control chip for performing the flow. The flow in fig. 6 includes the steps of:

s602: and the control chip detects whether the folding screen is in a folding state or not.

S604: if yes, near field communication is carried out with the near field communication additional antenna coil and the close induction object so as to interact service information.

In the folded state, the near field communication antenna coil 106 is disposed between the display screen 1022 and the transparent cover plate 1042, and thus is further folded to the inside, which may adversely affect the signal. To prevent this from affecting the near field communication interaction, an additional antenna coil for near field communication at the outer cover plate may be enabled, enabling signal quality.

Further, since the near field communication additional antenna coil is disposed relatively far enough outward, it can be made relatively smaller, mainly for assistance, thus contributing to a reduction in cost while also reducing the wear probability.

S606: otherwise, near field communication is carried out with the close induction object through the near field communication antenna coil so as to interact service information.

In the open state, the advantage of the near field communication antenna coil 106 can be fully exerted, and therefore, the near field communication antenna coil 106 can be preferentially used.

In one or more embodiments of the present description, the near field communication device further includes a control chip, a near field communication additional antenna coil, and a stylus pen wirelessly connected with the body part 102; near field communication additional antenna coils are deployed on the touch pen; the control chip is used for judging whether the touch pen passes through the near field communication additional antenna coil or not, and establishing near field communication with an induction object of the near field communication equipment; if yes, the main body part is made to establish near field communication with the induction object not through the near field communication antenna coil, but indirectly through the touch pen to perform interaction processing with the induction object. The near field communication additional antenna coil can be made of nano silver wires, is convenient to be reliably deployed on a narrow entity such as a stylus based on the characteristics of flexibility and thinness, can be deployed on the outer surface or the inner surface of the stylus, and particularly can be deployed in a region near the pen point of the stylus, so that accurate positioning near field communication is facilitated, and the position is located.

Through the indirect communication mode, a user can approach an induction object (which can be fixed or mobile) through a portable and handy touch pen so as to realize near field communication service interaction between near field communication equipment and the induction object, the reliability is good, the operation is convenient (the hand-held touch pen can accurately point to the induction object which wants near field communication interaction), the near field communication induction range is greatly enlarged, and even in the case that the induction object also comprises the touch pen, both sides can also realize the near field communication between the equipment behind each other through the touch pen.

The above is an example in which the near field communication antenna coil 106 made of nano silver wire is disposed between the main body part 102 and the housing part 104. Based on the same idea, one or more embodiments of the present disclosure further provide a schematic structural diagram of another near field communication device, see fig. 7.

The near field communication device in fig. 7 comprises a body part 102, a housing part 104, a near field communication antenna coil 106;

the housing part 104 covering the main body part;

The near field communication antenna coil 106 is made of nano silver wire, and is disposed on the outer surface of the housing part 104 or buried in the housing part 104. Therefore, the distance between the near field communication antenna coil 106 and the induction object can be further reduced, and the near field communication efficiency and the success rate can be improved.

More specific embodiments may be similarly implemented with reference to the above description, and will not be repeated here.

In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable GATE ARRAY, FPGA)) is an integrated circuit whose logic functions are determined by user programming of the device. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented with "logic compiler (logic compiler)" software, which is similar to the software compiler used in program development and writing, and the original code before being compiled is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but HDL is not just one, but a plurality of 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）, and VHDL (Very-High-SPEED INTEGRATED Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application SPECIFIC INTEGRATED Circuits (ASICs), programmable logic controllers, and embedded microcontrollers, 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 may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.

The system, apparatus, module or unit set forth in the above embodiments may be implemented in particular by a computer chip or entity, or by a product having a certain function. One typical implementation is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

For convenience of description, the above devices are described as being functionally divided into various units, respectively. Of course, the functions of each element may be implemented in one or more software and/or hardware elements when implemented in the present specification.

It will be appreciated by those skilled in the art that the present description may be provided as a method, system, or computer program product. Accordingly, the present specification embodiments may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, the present description embodiments may take the form of a computer program product on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, etc.) having computer-usable program code embodied therein.

The present description is described with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems) and computer program products according to embodiments of the specification. It will be understood that each flow and/or block of the flowchart illustrations and/or block diagrams, and combinations of flows and/or blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.

These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

In one typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.

The memory may include volatile memory in a computer-readable medium, random Access Memory (RAM) and/or nonvolatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of computer-readable media.

Computer readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of storage media for a computer include, but are not limited to, phase change memory (PRAM), static Random Access Memory (SRAM), dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), read Only Memory (ROM), electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium, which can be used to store information that can be accessed by a computing device. Computer-readable media, as defined herein, does not include transitory computer-readable media (transmission media), such as modulated data signals and carrier waves.

It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.

The description may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The specification may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.
