DETAILED DESCRIPTION

The features and exemplary embodiments of various aspects of the present application are described in detail below. In the following detailed description, many specific details are set forth in order to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without some of these specific details. The following description of the embodiments is intended only to provide a better understanding of the present application by illustrating examples of the present application.

It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The embodiments will be described in detail below in conjunction with the accompanying drawings.

Relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation; they do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion; so that a process, method, article or apparatus that includes a series of elements includes not only those elements; but also other elements not explicitly listed; or also includes elements inherent to such process, method, article or apparatus. In the absence of more limitations; the elements defined by the sentence "comprises..."; does not exclude the existence of other identical elements in the process, method, article or apparatus that includes the elements.

It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or region, it may mean that it is directly on the other layer or region, or that other layers or regions are included between it and the other layer or region. Furthermore, if the component is turned over, the layer or region will be "below" or "beneath" another layer or region.

In addition, the term "and/or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and/or B can represent: A exists alone; A and B exist at the same time; B exists alone. In addition, the character "/" in this article generally indicates that the associated objects before and after are in an "or" relationship.

It should be understood that in the embodiment of the present application, "B corresponding to A" means that B is associated with A and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A; B can also be determined according to A and/or other information.

In the prior art, because mobile card readers such as mobile phones do not have contact card insertion ports, it is necessary to use an accessory card insertion device to complete fingerprint entry of smart cards such as fingerprint cards. If the NFC (Near Field Communication) function of mobile card readers such as mobile phones is used to directly close the card to enter smart card data, the NFC antenna of the mobile phone will be arranged in different positions, causing part of the smart card to be blocked, affecting the entry. For example, when entering fingerprints on a fingerprint card, most of the fingerprint card will be blocked due to the different layout positions of the NFC antenna of the mobile phone, causing inconvenience to enter fingerprints.

In order to solve the above problems, the wireless relay device provided in the embodiment of the present application, the first antenna unit and the second antenna unit can be used for communication with the mobile card reader device and the smart card respectively, and energy transmission and data interaction are performed through the radio frequency electromagnetic field. The data in the smart card is transmitted to the mobile card reader device through the wireless relay device, and there is no need to set up an additional control unit. The structure is simple and the operation is convenient.

Please refer to Figures 1 to 3. An embodiment of the present application provides a wireless relay device, including: a carrier 1; an antenna module 2, which is arranged on the carrier 1, and the antenna module 2 includes an electrically connected first antenna unit 21 and a second antenna unit 22. In the thickness direction of the carrier 1, the orthographic projection of the first antenna unit 21 on the carrier 1 and the orthographic projection of the second antenna unit 22 on the carrier 1 at least partially do not overlap, and one of the first antenna unit 21 and the second antenna unit 22 is used to communicate with the mobile card reader device 3, and the other is used to communicate with the smart card 4.

The wireless relay device provided in the embodiment of the present invention includes a carrier 1 and an antenna module 2, the antenna module 2 includes a first antenna unit 21 and a second antenna unit 22 which are electrically connected. In the present embodiment, the orthographic projection of the first antenna unit 21 on the carrier 1 and the orthographic projection of the second antenna unit 22 on the carrier 1 at least partially do not overlap, so that the first antenna unit 21 and the second antenna unit 22 can be used for the communication of the mobile card reader device 3 and the smart card 4 respectively. When in use, the mobile card reader device 3 and the smart card 4 can be placed above the first antenna unit 21 and the second antenna unit 22 respectively, so that the mobile card reader device 3 and one of the first antenna unit 21 and the second antenna unit 22 are coupled for two-way communication, and the smart card 4 and the other of the first antenna unit 21 and the second antenna unit 22 are coupled for two-way communication. Since the first antenna unit 21 and the second antenna unit 22 are electrically connected, energy transmission and data interaction are performed through the electromagnetic field of the radio frequency, and the data in the smart card 4 is transmitted to the mobile card reader device 3 through the wireless relay device, without the need to set up an additional control unit, the structure is simple, and the operation is convenient.

In this embodiment, the mobile card reader 3 may be a mobile device such as a mobile phone or a tablet, and the smart card 4 may be a card capable of storing data such as a fingerprint card, a transportation card, an access control card, or a bank card.

It is understandable that the carrier 1 is a part used to carry the antenna module 2. The specific shape and size of the carrier 1 are not particularly limited, as long as it can carry and accommodate the antenna module 2. In order to prevent the carrier 1 from affecting the communication of the first antenna unit 21 and the second antenna unit 22, the carrier 1 is usually made of non-conductive materials. For example, the carrier 1 can be made of materials other than metal, and the material of the carrier 1 includes at least one of plastic and leather. The material of the carrier 1 can specifically be PU (polyurethane) material. In order to facilitate carrying and be more beautiful, the material of the carrier 1 can be made of a material similar to a wallet or a card holder, so that the appearance of the wireless relay device package looks like a wallet or a card holder, which is convenient to carry.

Both the first antenna unit 21 and the second antenna unit 22 may be NFC (Near Field Communication) antenna units to implement wireless communication between the mobile card reader 3 and the smart card 4 within a short distance.

The first antenna unit 21 and the second antenna unit 22 are used to transmit wireless data signals with external NFC devices such as mobile terminals, smart cards 4, etc. through near-field coupling. For example, when in use, the first antenna unit 21 can receive wireless data signals from the smart card 4 and convert them into electrical signals, and use the second antenna unit 22 to transmit the data to the mobile card reader 3 through near-field coupling.

Please refer to FIG. 3 . Optionally, the wireless relay device further includes a circuit board 5 . The circuit board 5 is disposed on the carrier 1 . The first antenna unit 21 and the second antenna unit 22 are electrically connected to the circuit board 5 , respectively.

The first antenna unit 21 and the second antenna unit 22 of this embodiment may be planar antennas, which may be manufactured by using a physical vapor deposition process, a chemical vapor deposition process, an evaporation process, a sputtering process, an electroplating process or a chemical plating process.

The first antenna unit 21 and the second antenna unit 22 can be formed on the circuit board 5 by means of a printed circuit wiring process. The first antenna unit 21 and the second antenna unit 22 can be directly formed on the circuit board 5 by means of copper coating, etching and other processes. The first antenna unit 21 and the second antenna unit 22 can also be adhered to the circuit board 5 by means of adhesive materials, or the first antenna unit 21 and the second antenna unit 22 can be embedded in the circuit board 5 by means of pre-embedded means, or the antenna patterns of the formed first antenna unit 21 and the second antenna unit 22 can be pressed onto the circuit board 5 by means of other processes.

For example, when the first antenna unit 21 and the second antenna unit 22 are disposed on the circuit board 5, PCB circuit wiring can be adopted to form antenna routing on the circuit board 5. The thickness, size and shape of the circuit board 5 can be set according to the actual application product and application environment to meet different application requirements.

In a specific embodiment, the shape of the circuit board 5 can be square, for example, a rectangle or a square. The first antenna unit 21 and the second antenna unit 22 can also be made of ferrite material with anti-interference ability. The area, number of turns and shape of the first antenna unit 21 and the second antenna unit 22 can be different, and the shape can be customized according to the structure without special limitation.

In some optional embodiments, the circuit board 5 includes a functional circuit, and the functional circuit includes capacitors or inductors arranged in series and capacitors or inductors arranged in parallel.

For example, referring to Fig. 4, the first antenna unit 21 and the second antenna unit 22 are connected via the third capacitor C3 and the fourth capacitor C4 arranged in series and the first capacitor C1 and the second capacitor C2 arranged in parallel. Of course, inductors may also be used.

A matching network is formed by capacitors or inductors arranged in series and capacitors or inductors arranged in parallel, and has functions such as matching resonant frequency and EMC. For example, the functional circuit may include an antenna matching circuit, a receiving circuit, etc. The antenna matching circuit is used to perform impedance matching with the antenna module 2 when the frequency of the antenna module 2 is within the operating frequency range, thereby increasing the effective bandwidth of the antenna module 2. The antenna matching circuit can adjust the resonant frequency of the antenna, wherein the operating frequency range may be the operating frequency range in which the antenna module 2 is required for NFC sensing, such as around 13 MHz. The resonant frequency of the antenna module 2 can be adjusted according to actual needs by adjusting the parameters of the capacitor or inductor. The receiving circuit is used to convert the wireless data signal into an electrical signal

Please refer to Figure 5. In some optional embodiments, the antenna module 2 is buried inside the carrier 1, that is, the antenna module 2 can be pre-buried inside the carrier 1 and then pressed into shape to improve the fixing effect of the carrier 1 on the antenna module 2. At the same time, since the antenna module 2 is buried inside the carrier 1, the antenna module 2 can also be protected by the carrier 1 to avoid damage to the antenna module 2, thereby improving the reliability of the wireless relay device.

Alternatively, the antenna module 2 may be arranged outside the carrier 1. For example, referring to FIG. 3, a groove K may be arranged on one side of the carrier 1, and the antenna module 2 is arranged in the groove K. The depth of the groove K needs to be selected according to the size of the antenna module 2 and the size and setting position of the circuit board 5. For example, when the antenna module 2 and the circuit board 5 are arranged in the groove K at the same time, by adjusting the depth of the groove K, the surface of the first antenna unit 21 and the second antenna unit 22 of the antenna module 2 facing away from the carrier 1 can be flush with or higher than the surface of the carrier 1, so as to facilitate the mobile card reading device 3, the smart card 4 and the first antenna unit 21. The first antenna unit 21 and the second antenna unit 22 are in contact with each other, or, in order to facilitate the positioning between the mobile card reading device 3, the smart card 4 and the first antenna unit 21 and the second antenna unit 22, the size of the groove K can also be set to be slightly larger than the size of the mobile card reading device 3 and the smart card 4, and the surface of the first antenna unit 21 and the second antenna unit 22 of the antenna module 2 facing away from the carrier 1 is slightly lower than the surface of the carrier 1, so that the mobile card reading device 3 and the smart card 4 can partially extend into the groove K, and the groove K is used to achieve alignment and connection, so as to facilitate the accurate connection between the mobile card reading device 3, the smart card 4 and the first antenna unit 21 and the second antenna unit 22.

In this embodiment, the circuit board 5 can be fixed in the groove K together with the antenna module 2 , or the circuit board 5 can be provided separately. For example, the antenna module 2 can be fixed in the groove K, and the circuit board 5 can be buried in the carrier 1 .

Please refer to Fig. 6, in some other optional embodiments, the antenna module 2 is attached to one side surface of the carrier 1. In this embodiment, the antenna module 2 can be directly attached to one side surface of the carrier 1, and when the antenna module 2 is provided on the flexible circuit board 5, the flexible circuit board 5 can also be attached to one side surface of the carrier 1, that is, the antenna module 2 is indirectly attached to one side surface of the carrier 1, which is convenient for replacement and maintenance.

Please refer to Figure 7. In some optional embodiments, the carrier 1 includes a first part 11 and a second part 12 connected to each other, and the first part 11 and the second part 12 can be folded; the first antenna unit 21 and the second antenna unit 22 are respectively arranged on one of the first part 11 and the second part 12.

It can be understood that, since the first part 11 and the second part 12 of the carrier 1 can be folded, the corresponding wireless relay device has a folded state and an unfolded state. In the unfolded state, the first antenna unit 21 and the second antenna unit 22 are flattened and exposed to facilitate cooperation with the mobile card reader 3 and the smart card 4. In the folded state, the first part 11 and the second part 12 can be arranged relative to each other, so that when the wireless relay device is not working, it is easy to carry.

The first antenna unit 21 and the second antenna unit 22 are respectively disposed on one of the first portion 11 and the second portion 12 to avoid mutual interference between the first antenna unit 21 and the second antenna unit 22 .

In some optional embodiments, the first antenna unit 21 and the second antenna unit 22 are reused as a wireless charging unit. When the wireless relay device is working, the first antenna unit 21 and the second antenna unit 22 can obtain energy from the electromagnetic field emitted by the mobile card reader 3, and transmit the obtained energy to the smart card 4, providing energy for the smart card 4 without the need for additional batteries.

Optionally, along the thickness direction of the carrier 1, the orthographic projection of the first antenna unit 21 on the circuit board 5 and the orthographic projection of the second antenna unit 22 on the circuit board 5 do not overlap, that is, the first antenna unit 21 and the second antenna unit 22 need to be respectively arranged at different positions of the circuit board 5 to avoid mutual interference between the two.

Please refer to Figure 8. Considering that there may be multiple mobile card reading devices 3 and smart cards 4, in this embodiment, a third antenna unit 23 may be additionally provided, that is, the antenna module 2 also includes a third antenna unit 23. In the thickness direction of the carrier 1, the orthographic projection of the third antenna unit 23 on the carrier 1 and the orthographic projections of the first antenna unit 21 and the second antenna unit 22 on the carrier 1 are at least partially non-overlapping.

It is understandable that the third antenna unit 23 can be used to communicate with any one of the mobile card reader device 3 and the smart card 4 to improve the working efficiency of the wireless relay device. Of course, more antenna units can be set according to actual needs, for example, four or five antenna units can be set, etc., without special limitation.

Please refer to Figure 9. In order to adapt to the use scenario where the mobile card reader 3 and the smart card 4 are far apart, an extension line Y can be used to increase the distance between the first antenna unit 21 and the second antenna unit 22. Specifically, the wireless relay device also includes an extension line Y, which connects the first antenna unit 21 and the second antenna unit 22 respectively. The length of the extension line Y is greater than or equal to 2 cm. The length of the extension line Y can be selected according to actual needs. When the extension line Y is less than 20 cm, conventional copper core wiring can also be used. When the length of the extension line Y is longer, from 20 cm to several meters or even longer, the extension line Y can use a coaxial cable. Coaxial cable is a kind of wire and signal transmission line, generally made of four layers of material: the innermost is a conductive copper wire, the outside of the wire is surrounded by a layer of plastic (used as an insulator, dielectric), the outside of the insulator is surrounded by a thin mesh conductor (generally copper or alloy), and the outside of the conductor is the outermost insulating material as the outer skin.

The extension line Y may be integrated with the antenna module 2 or may be a separate module.

The following takes the mobile card reader 3 as a mobile phone and the smart card 4 as a fingerprint card as an example to illustrate the fingerprint card entry process. During the fingerprint entry process, the mobile phone and the fingerprint card are both placed in the wireless relay device, for example, the mobile phone is placed on the first antenna unit 21 and the fingerprint card is placed on the second antenna unit 22.

The process is as follows: start the NFC function of the mobile phone; open the APP of the mobile phone to start communication, and provide energy to the fingerprint card through the wireless relay device (the energy mobile phone transmits to the first antenna unit 21, the second antenna unit 22, and the fingerprint card in sequence); the mobile phone sends an initialization command to initialize the settings of the wireless relay device; the mobile phone sends a fingerprint entry command; the wireless relay device transmits the fingerprint data contained in the fingerprint card to the mobile phone; the fingerprint entry is completed and the status value is returned.

The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
