[0003] However, due to the limitations of existing technologies, the following problems arise: (1) The RFID reader and RFID module can only achieve a single interaction. For example, when a user closes a game app and needs to reopen it through RFID technology, they need to first remove the RFID module, move it away from the reading area of ​​the RFID reader, and then re-approach the reading area of ​​the RFID reader to trigger the opening of the game app. The interactive experience is poor, and the RFID module is easily lost after being removed. (2) Generally speaking, an RFID module has only one chip, so it can only have one piece of information that can be compiled, which cannot meet more diverse needs. Technical issues

[0007] In order to solve the above technical problems, another technical solution adopted by the present invention is:

[0008] A method for controlling an RFID module adapted for an electronic product, comprising:

[0009] Execute the RFID module start or stop or select one of the conduction commands;

[0010] According to the RFID module start command, the channel connection of the signal transmission between the RFID module and the RFID reader is controlled; or according to the RFID module stop command, the signal transmission channel between the RFID module and the RFID reader is controlled to be interrupted; or according to the RFID module selection conduction command, the circuit where one chip of at least two chips in the RFID module is located is controlled to remain conductive.

Modes for Carrying Out the Invention

[0032] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0033] Referring to FIG1 , an RFID module adapted for electronic products includes a chip, a coil, and a control component. The chip and the coil are connected in series to form a loop. The control component is used to execute a start or stop command or a conduction command for the RFID module, thereby connecting or disconnecting a signal transmission channel between the RFID module and the RFID reader, or to keep the loop containing one of the at least two chips in the RFID module conductive.

[0034] From the above description, it can be seen that the beneficial effects of the present invention are: the RFID module is composed of a chip, a coil and a control component, so that when interacting with the RFID reader through the RFID module, there is no need to remove the RFID module, but by controlling the signal transmission between the RFID reader and the RFID module to be on or off or connected, it is more convenient to operate, thereby solving the problem in the prior art that the RFID reader and the RFID module can only be triggered once; by setting 2 or more chips, the user can set different compilable information in multiple chips respectively, and after selecting one to be turned on, different interactive functions can be realized accordingly.

[0035] Furthermore, it also includes a module carrier, and the chip and the coil are arranged on the module carrier; the control component includes a first elastic member and a first control member; one end of the first elastic member is connected to the first control member, and the other end of the first elastic member is connected to the module carrier; the first control member is used to execute the RFID module start or stop or select a conduction command, and control the release or reset of the first elastic member.

[0036] From the above description, it can be seen that by further setting up a module carrier, setting the chip and the coil on the module carrier, and connecting the two ends of the first elastic member to the module carrier and the first control member respectively, when the first control member executes the start or stop command, the first elastic member is controlled to release or reset, thereby driving the chip and coil on the module carrier to move, so that the coil is close to or away from the reading area of ​​the RFID reader, thereby realizing the interaction between the RFID module and the RFID reader.

[0037] Furthermore, the first elastic member includes a tension spring, a compression spring or a torsion spring.

[0038] From the above description, it can be seen that a tension spring, a compression spring or a torsion spring is used as the first elastic member, so that a tension spring, a compression spring or a torsion spring can be selected according to the actual usage scenario to control the RFID module to interact with the RFID reader in a linear motion or rotational motion manner.

[0039] Furthermore, the control assembly further comprises a first shielding plate; the first shielding plate is arranged at an initial position or an end position in the movement direction of the module carrier;

[0040] And the first shielding plate is arranged between the module carrier and the RFID reader.

[0041] From the above description, it can be seen that by setting the first shielding plate at the initial position or the end position in the movement direction of the module carrier, when it is necessary to disconnect the interaction between the RFID module and the RFID reader, the first shielding plate can effectively isolate the signal between the RFID module and the RFID reader.

[0042] Furthermore, the control component also includes a second elastic member, a second control member and a second shielding plate; one end of the second elastic member is connected to the second control member, and the other end of the second elastic member is connected to the second shielding plate; the second control member is used to start or stop the RFID module and control the release or reset of the second elastic member; the coil is set at the initial position or end position in the movement direction of the second shielding plate, and the second shielding plate is movably set between the module carrier and the RFID reader.

[0043] From the above description, it can be seen that by setting a second elastic member, a second control member and a second shielding plate, and setting the coil at the initial position or the end position in the movement direction of the second shielding plate, when it is necessary to disconnect the interaction between the RFID module and the RFID reader, the second elastic member and the second control member are used to control the movement of the first shielding plate, so that the signal between the RFID module and the RFID reader can be effectively isolated.

[0044] Furthermore, the control component, the chip, and the coil are sequentially connected in series; the control component is used to execute a command to start or stop the RFID module or to selectively conduct one of them, thereby opening or conducting the circuit between the chip and the coil;

[0045] The control component includes at least one sub-control switch, and the sub-control switch includes a mechanical switch or an electronic switch.

[0046] As can be seen from the above description, by connecting the control component in series to the circuit of the chip and the coil, the control component can be used to control the on or off of the series circuit, thereby realizing the interaction between the RFID module and the RFID reader.

[0047] Furthermore, it comprises at least two chips; the chips are connected in series with the coil and the control component respectively.

[0048] From the above description, it can be seen that by setting up multiple groups of chips that realize different functions in parallel between the coil and the control component, different chips can be activated to interact with the RFID reader according to different functional requirements to achieve different functional effects.

[0049] Furthermore, the control component includes sub-control switches whose number is the same as the number of the chips; each of the chips is connected to one of the sub-control switches.

[0050] Furthermore, the control component includes sub-control switches whose number is different from the number of the chips; at least two chips are connected to the same sub-control switch and are selectively turned on through the sub-control switch.

[0051] It can be seen from the above description that by providing a sub-control switch for each chip, different chip functions can be triggered by each sub-control switch.

[0052] Another embodiment of the present invention provides a method for controlling an RFID module adapted for an electronic product, comprising:

[0053] Execute the command to start, stop or turn on the RFID module;

[0054] connecting a signal transmission channel between the RFID module and the RFID reader according to the RFID module startup command;

[0055] or interrupting a signal transmission channel between the RFID module and the RFID reader according to the RFID module stop command;

[0056] Or the circuit between a certain chip and the coil remains conductive.

[0057] From the above description, it can be seen that when the RFID module interacts with the RFID reader, the signal transmission between the RFID reader and the RFID module is controlled by commands to be on or off or connected, which is more convenient to operate and there is no need to remove the RFID module, thereby solving the problem in the existing technology that the RFID reader and the RFID module can only be triggered once; by setting up 2 or more chips, the user can set different compilable information in multiple chips respectively, and after selecting one to be turned on, different interactive functions can be realized accordingly.

[0058] Another embodiment of the present invention provides a device, including the above-mentioned RFID module adapted for electronic products, and also including a shell and a switch; the switch is arranged on the outer surface of the shell; the RFID module is arranged inside or on the outer surface of the shell; the switch is connected to the control component.

[0059] From the above description, it can be seen that by setting a switch on the outside of the shell and connecting the switch to the control component, the user can directly control the interaction between the RFID reader and the RFID module through the switch on the outside of the shell. At the same time, setting the RFID module inside the shell can also avoid the loss of the RFID module and make the operation more convenient, solving the problem in the prior art that the RFID reader and the RFID module can only be triggered once or there is only one chip available for compiling information.

[0060] The coil described in the present invention is also called an antenna in the industry and plays a role in energy and information transmission.

[0061] The RFID module, control method, and device adapted for electronic products of the present invention are applicable to different RFID module identification scenarios, such as being set on electronic products or on supporting devices of electronic products to implement RFID module identification functions. The following is an explanation of the specific implementation methods:

[0062] Example 1

[0063] Please refer to Figure 1, an RFID module adapted for electronic products includes a chip 1, a coil 2 and a control component 3; the chip 1 and the coil 2 are connected in series; the control component 3 is used to control the circuit connection of the chip 1 and the coil 2, so that the signal transmission channel between the RFID module and the RFID reader is connected or disconnected.

[0064] Please refer to Figure 1. The control component 3, chip 1 and coil 2 are connected in series in sequence. The control component 3 is used to start or stop the RFID module, so that the circuit between the chip 1 and the coil 2 is disconnected or connected: the RFID module with the structure of Figure a in Figure 1 has only one chip 1, and the control component 3 adopts the form of a mechanical switch. This structural method can simplify the structure and obtain a thinner RFID module structure. The disadvantage is that the function is single.

[0065] In an optional embodiment, different RFID module functions are triggered by increasing the number of the chips 1; that is, the coil 2 includes at least two chips 1, and the chips 1 are respectively connected in series with the coil 2 and the mechanical switch, wherein the mechanical switch controls at least one chip 1; at the same time, different chips 1 can be connected to different coils 2 for circuit connection, such as each chip 1 corresponds to one coil 2; similarly, the circuit connection can be made by freely combining the number of chips 1 and coils 2, such as two chips corresponding to one coil, etc.; the information encoding carried by the chip 1 can be any compilable information.

[0066] In an optional embodiment, the control component 3 includes the same number of mechanical switches as the chips 1; that is, each chip 1 is connected to a mechanical switch, so that different mechanical switches activate the corresponding chip 1. As shown in Figures b and c of Figure 1, two or more mechanical switches are used to achieve circuit conduction for the corresponding chip 1.

[0067] Please refer to Figure 2. In another optional embodiment, the circuits of multiple chips 1 are selectively turned on by the same mechanical switch, that is, the chip 1 and the mechanical switch are in a many-to-one relationship; by setting different travel gears for the mechanical switch, the mechanical switch corresponds to the multiple chips 1. As shown in Figures 2b and 2c of Figure 2, the RFID module includes 2 or more chips 1 that carry information coding, and each chip 1 is connected and disconnected by the same mechanical switch. Among them, the chip 1 and the mechanical switch can also be in a many-to-many relationship, such as 3 chips 1 are controlled by 2 mechanical switches. Normally, the many-to-one mechanical switch is used to execute the command of selectively turning on, so that the circuit where a certain chip is located remains conductive.

[0068] Among them, the types of mechanical switches include pot-type buttons (such as closing the circuit of any chip 1 by selecting and pressing different pot-type buttons), soft rubber buttons (such as buttons used in remote controls), membrane keys (such as keys used inside keyboards), knobs, mechanical press-on switches / keys / buttons, disconnect type buttons / switches / keys and toggle switches.

[0069] In another optional embodiment, the mechanical switch is replaced by an electronic switch;

[0070] Referring to Figure 3, an electronic switch component is drawn from the circuit of the RFID module, and on-off control is achieved through the electronic switch component and the controller;

[0071] The electronic switch components include MOS transistors, transistors, relays, solid-state relays, optocouplers, analog switches, and any other electronic component with a switching function. The controller includes a programmable device such as a single-chip microcomputer. The controller can selectively close any electronic switch component, such as opening all electronic switch components, selecting specific electronic switch components to close or open, or maintaining the state of an electronic switch component. The controller controls at least one electronic switch to implement the corresponding RFID module function, and is not limited to triggering the corresponding RFID module function through tapping, shaking, pressing, touching, etc. At the same time, the electronic switch component is powered by an external power supply or an external / internal storage device.

[0072] Maintaining the state of the electronic switch components mentioned above means maintaining the original state, for example, if it was originally closed, it will remain closed, and if it was originally open, it will remain open.

[0073] Example 2

[0074] This embodiment differs from the first embodiment in that the signal transmission channel between the RFID module and the RFID reader is connected or interrupted by a non-circuit control method. Specifically, the control component 3 is used to execute the command to start or stop the RFID module, control the movement of the module carrier 4, and connect or interrupt the signal transmission channel between the RFID module and the RFID reader; or keep the circuit where one of the at least two chips in the RFID module is located conductive. Specifically,

[0075] Please refer to Figures 4 and 6, which include a module carrier 4, on which the chip 1 and the coil 2 are arranged; the control component 3 includes a first elastic member 31 and a first control member 32; one end of the first elastic member 31 is connected to the first control member 32, and the other end of the first elastic member 31 is connected to the module carrier 4; the first control member 32 is used to execute the start or stop or select a conduction command of the RFID module, and control the release or reset of the first elastic member 31; optionally, the control component 3 can control the movement of the RFID module including: linear reciprocating motion, curved reciprocating motion or rotational motion.

[0076] As shown in FIG4 , the first elastic member 31 includes a tension spring or a compression spring, which is used to make the RFID module move linearly. When the control component 3 executes the start command, the tension spring is released, so that the RFID module moves to the reading area. After the reading is completed, the automatic reset can be set, or a reset signal can be sent to control the tension spring to reset, so that the RFID module is reset. The corresponding reset method can be selected according to the specific application scenario. Referring to FIG5 , in another optional embodiment, at least two RFID modules are included; different interactive functions are achieved by controlling different RFID modules. At the same time, different function triggering can also be achieved by increasing the number of chips 1. For example, a single RFID module includes two or more chips 1 with different information encoding.

[0077] As shown in Figure 6, the first elastic member 31 is a torsion spring, which is used to make the RFID module rotate. The torsion spring includes a left-handed torsion spring or a right-handed torsion spring, and the angle includes 0°-270°, which can be set according to the specific structure, such as selecting angles of 0°, 60°, 90° and 120°. Specifically, a rotating shaft is set, and a baffle is set at an appropriate position, and the torsion spring is sleeved on the rotating shaft. One end of the torsion spring is fixed and the other end is connected to the RFID module. At the same time, the control component 3 has a reset function, which is used to reset the moved RFID module. When the control component 3 is in working state, the RFID module enters the reading area; when the control component 3 is in reset state, the RFID module is outside the reading area. Among them, at least two RFID modules and a corresponding number of torsion springs can also be set, so that different functions can be achieved by controlling different torsion springs.

[0078] In another optional embodiment, the control component 3 further includes a first shielding plate 33, which is a plate made of a metal conductive material; the first shielding plate 33 is arranged at an initial position or an end position in the movement direction of the module carrier 4, and the first shielding plate 33 is arranged on one side between the module carrier 4 and the RFID reader, for enhancing the shielding effect (shielding function) of the area blocked by the first shielding plate 33; that is: when the first shielding plate 33 is set at the initial position in the movement direction of the module carrier 4, and the position of the RFID reader does not correspond to the position of the RFID module, the shielding function is not turned on by default, and the shielding function is turned on after moving; when the first shielding plate 33 is set at the end position in the movement direction of the module carrier 4, and the position of the RFID reader corresponds to the position of the RFID module, the shielding function is turned on by default.

[0079] Example 3

[0080] The difference between this embodiment and the first or second embodiment is that the signal transmission channel between the RFID module and the RFID reader is connected or interrupted by controlling the shielding plate; or the loop where one of the at least two chips in the RFID module is located is kept conductive.

[0081] Please refer to Figure 7, the control component 3 also includes a second elastic member 34, a second control member 35 and a second shielding plate 36; the second shielding plate 36 is a plate made of metal conductive material; one end of the second elastic member 34 is connected to the second control member 35, and the other end of the second elastic member 34 is connected to the second shielding plate 36; the second control member 35 is used to execute the RFID module start or stop or select a conduction command, and control the release or reset of the second elastic member 34; the module carrier 4 is arranged at the initial position or end position in the movement direction of the second shielding plate 36, and the second shielding plate 36 is arranged between the module carrier 4 and the RFID reader; optionally, the second elastic member 34 includes a tension spring, a compression spring or a torsion spring, so that the control component 3 can control the RFID module to perform linear reciprocating motion, curved reciprocating motion or rotational motion.

[0082] For example, the RFID reader position is set to correspond to the RFID module position;

[0083] The initial position of the second shielding plate 36 in the movement direction can be set between the RFID reader and the RFID module, then the shielding function is turned on by default, the signal transmission channel between the RFID module and the RFID reader is interrupted, and after moving, the shielding function is turned off, and the signal transmission channel between the RFID module and the RFID reader is connected; or the end position of the second shielding plate 36 in the movement direction can be set between the RFID reader and the RFID module, then the shielding function is turned off by default, and after moving, the shielding function is turned on.

[0084] Furthermore, different function triggering can be achieved by increasing the number of chips 1. For example, a single RFID module can include two or more chips 1 carrying different information codes. Alternatively, the number of RFID modules can be increased to achieve different function triggering. Furthermore, the structure of this embodiment can be combined with the structure of the first embodiment.

[0085] Example 4

[0086] Referring to FIG. 8 , a method for controlling an RFID module adapted for an electronic product includes the following steps:

[0087] S1, execute the RFID module start or stop or select one of the conduction commands;

[0088] S2a, connecting the signal transmission channel between the RFID module and the RFID reader according to the RFID module startup command;

[0089] S2b, or according to the RFID module stop command, interrupting the signal transmission channel between the RFID module and the RFID reader;

[0090] S2c, or according to a conduction command selected by the RFID module, controlling the circuit where a certain chip in the RFID module is located to remain conductive.

[0091] The control method in this embodiment is applicable to the above-mentioned embodiments 1, 2 and 3, and serves as the control method corresponding to the control component 3.

[0092] Example 5

[0093] A device, which can be a supporting bracket (desktop bracket, car bracket), charging device or shell accessory for a mobile smart terminal such as a mobile phone, tablet computer, smart headset, smart watch, etc., specifically: it includes an RFID module adapted for electronic products as described in Examples 1, 2 and 3, and also includes a shell 5 and a switch 6; the switch 6 is arranged on the outer surface of the shell 5; the RFID module is arranged on the inner surface or outer surface of the shell 5; the switch 6 is connected to the control component 3.

[0094] The RFID module can be installed within the reading area of ​​an NFC-enabled electronic product, directly on the electronic product, or on an accessory device of the electronic product. Electronic products include smartphones, smartwatches, gaming devices, etc. equipped with NFC functionality. Accessory devices include protective cases that fit snugly with the electronic product, desktop or car charging products, mounting brackets, magnetic rings, etc.

[0095] Referring to Figure 9 , the RFID module is installed on an electronic product's supporting equipment. For example, the RFID module structure corresponding to the solution in Example 1 is installed on a smartphone's protective case, corresponding to the NFC reading area of ​​the brand and model of the phone, and requiring that the protective case's area not provide magnetic field shielding. When the phone is installed in the case, the RFID module is relatively fixed to the phone, eliminating the need for separate storage. The RFID module includes three chips 1, each used to trigger the following actions: Action 1: Open a game app; Action 2: Pop up a battery reminder page; Action 3: Switch to an instant messaging software app.

[0096] Referring to Figure 10 , the RFID module is directly mounted on an electronic product, such as the RFID module structure described in Example 1, mounted on the charging panel of a vehicle-mounted charging stand. This corresponds to the NFC reading area of ​​the smartphone after attachment, and this area of ​​the charging panel does not provide magnetic field shielding. The RFID module includes two chips 1, each used to trigger the following actions: Action 1: Open a navigation app; Action 2: Open a music app; and Action 3: Other custom functions. In Figure 10 , at least one of the circuits containing chips 1 remains conductive.

[0097] Among them, the specific loading information in the above example can be customized by downloading the corresponding mobile phone software. The mechanical switch 6 can adopt a pot piece button, and different mechanical switches 6 can be distinguished by color, shape, and feel, so as to help users quickly locate a certain mechanical switch 6; or a pull switch 6 button can be used, and different profiles can be set to make the circuit where one chip 1 is located in the on state.

[0098] At the same time, in order to ensure the flatness and fit of the entire RFID module structure, the thickness needs to be controlled so that the RFID module structure is always fixed relative to the electronic product or other equipment. The thickness of the RFID module structure in Example 1 is less than 2 mm, preferably 0.5-1 mm. The thickness of the RFID module structure in Examples 2 and 3 is less than 5 mm, preferably less than 3.5 mm.

[0099] Example 6

[0100] This embodiment is a specific implementation scheme of setting the RFID module structure corresponding to the solution in Example 1 on the charging panel of the vehicle charging bracket. Specifically:

[0101] Referring to Figures 11 and 12, a vehicle-mounted bracket with an RFID chip includes a housing 5, a chip 1 (not shown in Figures 11-12, but disposed on the back of a second PCB board 704, as shown in Figure 13), a switch 6, and a circuit assembly 7. The chip 1 and the switch 6 are both disposed within the housing 5. A relief hole is provided on a surface of the housing 5, and the switch 6 is at least partially disposed within the relief hole.
