[0037] As an electronic device designed for children, the development and popularization of learning machines have become an important part of modern education. With the advancement of technology, learning machines have been significantly improved in design and function, such as more intelligent interface design, rich learning applications and integration of interconnection functions. These improvements make learning machines an indispensable educational tool in families and schools.

[0038] However, current learning machines have complex operation problems in some interactive functions. For example, in terms of adding friends and interacting with them, users are usually required to manually enter the other party's account number for search and verification, which is too complicated and unfriendly for younger children.

[0039] Based on this, at least one embodiment of the present disclosure provides a learning machine and a near field communication card.

[0040] The first aspect of the present disclosure provides a learning machine, such as Figure 1As shown, the learning machine 100 includes a body shell 101, a main control chip 102, a near field communication module 103 and a near field communication antenna 104. The main control chip 102 is arranged in the body shell 101; the near field communication module 103 is electrically connected to the main control chip 102; the near field communication antenna 104 is arranged in the body shell 101 and is electrically connected to the near field communication module 103.

[0041] The main control chip 102 may be the central core of the learning machine 100, used to manage the various functions and operations of the learning machine 100. The near field communication module 103 in the present disclosure is an NFC (Near Field Communication) module. NFC refers to a short-range high-frequency wireless communication technology that allows devices to exchange data without contact. The near field communication antenna 104 in the present disclosure is an NFC antenna that can send and receive signals. Further, as Figure 1 As shown, the near field communication antenna 104 is located on the inner wall of the body shell 101, which can reduce the path loss of signal transmission and reduce interference from the surrounding environment and other electronic devices, and can improve the stability and efficiency of receiving and sending signals.

[0042] The near field communication module 103 is used to radiate signals outward through the near field communication antenna 104 based on the control instruction of the main control chip 102 , and / or send signals received by the near field communication antenna 104 to the main control chip 102 .

[0043] Specifically, in response to the need for the main control chip 102 to send information outward, the near-field communication module 103 can receive a control instruction initiated by the main control chip 102 for sending information outward, and based on the control instruction initiated by the main control chip 102, radiate a signal outward through the near-field communication antenna 104 to send information outward; and / or, in response to the near-field communication antenna 104 receiving a signal, the received signal can be sent to the near-field communication module 103, and the near-field communication module 103 sends the received signal to the main control chip 102, so that the main control chip 102 can process the received signal.

[0044] In the disclosed embodiment, a near-field communication module 103 and a near-field communication antenna 104 are added inside the learning machine 100. The near-field communication module 103 can radiate signals outward through the near-field communication antenna 104 based on the control instructions of the main control chip 102, and / or send the signals received by the near-field communication antenna 104 to the main control chip 102. The user does not need to perform complicated operations in interactions such as adding friends. Instead, information interaction can be automatically performed based on the near-field communication module 103 and the near-field communication antenna 104, making the operation of implementing the interactive function easier, more convenient for younger users, and improving the user experience.

[0045] In an exemplary embodiment, Figure 2 As shown, the learning machine 100 further includes a micro coaxial connector 105, and the micro coaxial connector 105 is respectively connected to the near field communication module 103 and the near field communication antenna 104, so that the near field communication module 103 and the near field communication antenna 104 are electrically connected.

[0046] Optionally, the micro coaxial connector 105, i.e., an IPEX connector (I-PEX Connectors), can be used to connect the near field communication module 103 and the near field communication antenna 104. The micro coaxial connector 105 has a compact design and is suitable for high frequency transmission, and can more reliably connect the near field communication module 103 and the near field communication antenna 104, so that the signal transmission between the near field communication module 103 and the near field communication antenna 104 is more stable.

[0047] Based on the above embodiments, in an exemplary embodiment, Figure 2 As shown, the learning machine 100 also includes a printed circuit board microstrip line 106, and the printed circuit board microstrip line 106 is connected to the micro coaxial connector 105 and the near field communication module 103 respectively, so that the micro coaxial connector 105 and the near field communication module 103 are electrically connected.

[0048] Optionally, a printed circuit board microstrip line 106, i.e., a PCB (Printed Circuit Board) microstrip line, can be used to connect the micro coaxial connector 105 and the near field communication module 103. The printed circuit board microstrip line 106 provides unlimited flexibility and precision on the printed circuit board, and can optimize the layout and signal transmission path according to the device design requirements, so that the transmission of high-frequency signals between the micro coaxial connector 105 and the near field communication module 103 is more stable.

[0049] In an exemplary embodiment, Figure 2As shown, the learning machine 100 further includes a radio frequency cable 107 , and the radio frequency cable 107 is respectively connected to the micro coaxial connector 105 and the near field communication antenna 104 , so that the micro coaxial connector 105 and the near field communication antenna 104 are electrically connected.

[0050] Optionally, the RF cable 107 is an RF Cable (Radio Frequency Cable). The RF cable 107 has high-frequency transmission capability, design flexibility and reliability. By connecting the micro coaxial connector 105 and the near-field communication antenna 104 through the RF cable 107, the transmission of high-frequency signals between the micro coaxial connector 105 and the near-field communication antenna 104 can be made more stable.

[0051] In an exemplary embodiment, Figure 3 As shown, the near field communication module 103 is connected to the main control chip 102 via a serial port bus 108 , so that the near field communication module 103 and the main control chip 102 can communicate via the serial port.

[0052] Optionally, the near field communication module 103 and the main control chip 102 can be connected via a serial port bus 108 to perform data communication and control signal transmission based on the serial port bus 108. The near field communication module 103 and the main control chip 102 communicate via a serial port, and different serial port protocols can be selected to meet different connection requirements, so that the data communication and signal transmission between the near field communication module 103 and the main control chip 102 can be more efficient, stable, and more adaptable.

[0053] In an exemplary embodiment, the near field communication module 103 is used to send interaction information to other learning machines 200 via the near field communication antenna 104; and / or,

[0054] The near field communication module 103 is used to receive interaction information sent by other learning machines 200 through the near field communication antenna 104, and send the interaction information to the main control chip 102, so that the main control chip 102 processes the interaction information.

[0055] It should be noted that the learning machine 100 can continuously radiate connection signals outward, or when the distance between it and other learning machines 200 is less than a preset distance threshold, it can receive connection signals radiated outward by other learning machines 200, and then automatically establish a near-field communication connection with other learning machines 200; then, based on the established near-field communication connection, the learning machine 100 and the other learning machines 200 can send and receive interactive information.

[0056] The interaction information refers to the information of the interaction between the learning machine 100 and other learning machines 200. The interaction information includes at least one of the following: wireless network information, Bluetooth information, and identity information.

[0057] Exemplarily, in the case where the interactive information is wireless network information, the wireless network information may include a wireless network name and a wireless network password. Optionally, based on the near field communication connection between the learning machine 100 and other learning machines 200, the near field communication module 103 may obtain the currently connected wireless network information from the main control chip 102, and transmit the wireless network information to the near field communication antenna 104, and send the wireless network information to other learning machines 200 through the near field communication antenna 104; and / or, the near field communication module 103 may receive the wireless network information sent by other learning machines 200 through the near field communication antenna 104, and send the wireless network information to the main control chip 102. After the main control chip 102 obtains the wireless network information, it can connect to the wireless network corresponding to the wireless network information according to the wireless network information.

[0058] It can be understood that in the scenario of helping other learning machines 200 to connect to the wireless network corresponding to the wireless network information, or needing the help of other learning machines 200 to connect to the wireless network corresponding to the wireless network information, compared with manually sharing or connecting the wireless network information, automatically sending or receiving the wireless network information based on the near-field communication connection between the learning machine 100 and the other learning machines 200 can more easily complete the operation of connecting or sharing the wireless network corresponding to the wireless network information, which is very friendly to younger users and improves the user experience.

[0059] Exemplarily, when the interactive information is Bluetooth information, the Bluetooth information may be Bluetooth address information. Optionally, based on the near field communication connection between the learning machine 100 and other learning machines 200, the near field communication module 103 may obtain its own Bluetooth information from the main control chip 102, and transmit the Bluetooth information to the near field communication antenna 104, and send the Bluetooth information to other learning machines 200 through the near field communication antenna 104; and / or, the near field communication module 103 may receive the Bluetooth information sent by other learning machines 200 through the near field communication antenna 104, and send the Bluetooth information to the main control chip 102. After the main control chip 102 obtains the Bluetooth information, it may search for the Bluetooth information and automatically pair.

[0060] It can be understood that in a scenario where Bluetooth pairing with other learning machines 200 is required, compared with manually sharing or searching for Bluetooth information, automatically sending or receiving Bluetooth information based on the near-field communication connection between the learning machine 100 and the other learning machines 200 can more easily complete the operation of sharing or pairing the Bluetooth corresponding to the Bluetooth information, which is very friendly to younger users and improves the user experience.

[0061] Exemplarily, in the case where the interactive information is identity information, the identity information may include one's own social account, device information, and friend adding request information. Optionally, based on the near field communication connection between the learning machine 100 and other learning machines 200, the near field communication module 103 may obtain the identity information from the main control chip 102, and transmit the identity information to the near field communication antenna 104, and send the identity information to other learning machines 200 through the near field communication antenna 104; and / or, the near field communication module 103 may receive the identity information sent by other learning machines 200 through the near field communication antenna 104, and send the identity information to the main control chip 102. After the main control chip 102 obtains the identity information, it may automatically execute the friend adding instruction according to the identity information.

[0062] It can be understood that in a scenario where it is necessary to add friends with other learning machines 200, compared to manually performing a series of operations to add friends, automatically sending and / or receiving identity information based on the near-field communication connection between the learning machine 100 and the other learning machines 200 can more easily complete the operation of adding friends based on the identity information, which is very friendly to younger users and improves the user experience.

[0063] Based on the above embodiments, in an exemplary embodiment, the main control chip 102 is used to send the identity information to the terminal device 300 bound to the learning machine 100 in response to receiving the identity information, and receive the control instructions sent by the terminal device 300 based on the identity information.

[0064] Among them, the terminal device 300 can be a terminal device pre-bound to the learning machine 100, such as a device of the user's parents, such as a mobile phone, tablet computer, etc.

[0065] Optionally, when the main control chip 102 receives the identity information sent by the near-field communication module 103, the identity information can be sent to the terminal device 300 bound to the learning machine 100; after receiving the identity information sent by the learning machine 100, the terminal device 300 can display the identity information to the user to which the terminal device 300 belongs, and the user to which the terminal device 300 belongs confirms whether the user to whom the identity information belongs is safe, and inputs a control instruction for passing or rejecting the identity information to the terminal device (for example, adding the identity information to the whitelist to pass the identity information), and sends the control instruction to the main control chip 102 of the learning machine 100; the main control chip 102 can add or reject the identity information according to the control instruction sent by the terminal device 300.

[0066] It can be understood that by sending the received identity information to the terminal device 300 bound to the learning machine 100 through the main control chip 102, and receiving the control instructions sent by the terminal device 300 based on the identity information, the learning machine 100 can be managed and controlled to ensure the safe and compliant use of the learning machine 100.

[0067] In an exemplary embodiment, Figure 3 As shown, the learning machine 100 also includes a near field communication card 109 .

[0068] The NFC card 109 refers to a card that can establish a NFC connection with the learning machine 100 or the terminal device 300 having a NFC function. The NFC card 109 may be pre-set with a storage area for storing information. The information may include identity information, book information, payment information, etc.

[0069] Optionally, the learning machine 100 may be close to the near field communication card 109, and when the distance between the learning machine 100 and the near field communication card 109 is less than a preset distance threshold, the learning machine 100 may establish a near field communication connection with the near field communication card 109; based on the established near field communication connection, the near field communication module 103 may write information to the near field communication card 109 through the near field communication antenna 104. The near field communication card 109 may store the information written by the near field communication module 103, so that other learning machines 200 can identify the information stored in the near field communication card 109.

[0070] Exemplarily, when a near-field communication connection is established between the learning machine 100 and the near-field communication card 109, the near-field communication module 103 can write identity information into the near-field communication card 109 through the near-field communication antenna 104, so that the near-field communication card 109 stores the identity information. In the case where the learning machine 100 cannot be carried (for example, during school hours, the school does not allow learning machines to be carried), the near-field communication card 109 storing the identity information can be used to implement the function of adding friends more portable and efficient.

[0071] The near field communication module 103 can also be used to identify information in the near field communication card 201 of other learning machines 200 through the near field communication antenna 104, and send the identified information to the main control chip 102 so that the main control chip 102 processes the identified information.

[0072] Optionally, the learning machine 100 can be close to the near-field communication card 201 of other learning machines 200. When the distance between the near-field communication card 201 of the learning machine 100 and the near-field communication card 201 of the other learning machine 200 is less than a preset distance threshold, a near-field communication connection is established between the near-field communication card 201 of the learning machine 100 and the other learning machine 200; based on the established near-field communication connection, the near-field communication module 103 can identify the information stored in the near-field communication card 201 through the near-field communication antenna 104, and transmit the identified information to the main control chip 102, so that the main control chip 102 processes the identified information.

[0073] Exemplarily, when a near-field communication connection is established between the learning machine 100 and the near-field communication card 201 of other learning machines 200, the near-field communication module 103 can identify the information stored in the near-field communication card 201 through the near-field communication antenna 104, and transmit the identified identity information to the main control chip 102, so that the main control chip 102 can process the identified identity information more efficiently to realize the function of adding friends.

[0074] It can be understood that by setting up a near-field communication card 109, the near-field communication module 103 can write information into the near-field communication card 109, or identify information in the near-field communication card 201 of other learning machines 200. In the case where it is impossible to carry the learning machine 100, by carrying a more portable near-field communication card 109, functions such as adding friends and making payments can be more efficiently realized, thereby improving the user experience.

[0075] In a second aspect, the present disclosure also provides a near field communication card 400, such as Figure 4As shown, the near field communication card 400 is used to radiate the information written by the learning machine 100 so that other learning machines 200 can recognize the information written by the learning machine 100.

[0076] Optionally, the learning machine 100 can be close to the near-field communication card 400. When the distance between the learning machine 100 and the near-field communication card 400 is less than a preset distance threshold, the learning machine 100 can establish a near-field communication connection with the near-field communication card 400; based on the established near-field communication connection, information is written to the storage area 401 in the near-field communication card 400; further, the near-field communication card 400 can radiate the information written by the learning machine 100 outward through the internal near-field communication antenna 402. When the near-field communication card 400 is close to other learning machines 200 and establishes a near-field communication connection, the other learning machines 200 can identify and process the information in the near-field communication card 400.

[0077] In this embodiment, a near-field communication card 400 is provided, and the near-field communication card 400 radiates the information written by the learning machine 100, so that other learning machines 200 can recognize and process the information in the near-field communication card 400. In the case where the learning machine 100 cannot be carried, by carrying a more portable near-field communication card 400, functions such as adding friends and making payments can be more efficiently realized, thereby improving the user experience.
