[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] See also Figures 1 to 3 As shown, according to one aspect of an embodiment of the present application, a pointer mirror is provided for reflecting light to a camera of an intelligent educational device, the pointer mirror comprises a communication element 1 and a connecting element 2, the communication element 1 is electrically connected to the connecting element 2, the connecting element 2 is arranged on the surface of the pointer mirror that contacts the intelligent educational device, the intelligent educational device is provided with an interface matching the connecting element 2 at a position relative to the connecting element 2, the connecting element 2 is electrically connected to the data transmission module 4 of the intelligent educational device via the interface, to form a radio frequency path.

[0026] It can be understood that in the present application, by providing a communication element 1 electrically connected to the data transmission module 4 of the intelligent educational device in the pointer mirror, the pointer mirror can be used as an external antenna of the intelligent educational device, thereby improving the signal strength and expanding the signal coverage range.

[0027] Among them, the learning mirror, also known as the AR mirror, is an accessory used in conjunction with smart educational devices such as learning machines. It can reflect light and expand the scanning range of smart educational devices such as learning machines, so that the front camera of smart educational devices such as learning machines can clearly identify text, pictures and charts on test papers or books, providing students with relevant learning assistance.

[0028] The finger-learning mirror comprises a mirror frame, which has a connecting bend, and the connecting bend is set on the display screen of intelligent educational equipment such as a learning machine, so as to achieve relative fixation of the finger-learning mirror and intelligent educational equipment such as a learning machine.

[0029] Specifically, the surface of the connecting bend that contacts the display screen of intelligent educational equipment such as a learning machine has a continuous semicircular protrusion, which makes the connection between the connecting bend and the display screen more stable and reduces the looseness or displacement that may occur during the use of the pointer; at the same time, the continuous semicircular protrusion creates a certain gap between the connecting bend and the display screen, which helps air circulation and promotes heat dissipation, thereby preventing intelligent educational equipment such as learning machines from overheating after long-term use, which may affect performance or shorten service life.

[0030] Among them, the part other than the connecting bend on the frame is the AR mirror body. In this embodiment, Figure 1 Part A is the body of the AR mirror. As an implementation, the side of the AR mirror body close to the test paper or book is a mirror structure; as another implementation, the side of the AR mirror body close to the test paper or book is provided with a lens. It should be noted that the AR mirror body can be a planar structure, an arc structure, a curved surface structure, a polyhedral structure, a stepped structure or an uneven structure, etc., and this embodiment does not make further limitations.

[0031] Among them, a communication element 1 is arranged in the AR mirror body, and the communication element 1 can be an antenna, specifically a PIFA antenna (Planar Inverted-F Antenna).

[0032] Among them, the AR mirror body can be made of materials such as plastic, glass or ceramic, so that the signals sent and received by the communication element 1 are stronger, the signal attenuation is reduced, and the signal coverage range is increased.

[0033] Among them, a connecting element 2 is also provided in the AR mirror body. The connecting element 2 can be a metal pin (PIN). The connecting element 2 is arranged at the position where the AR mirror body contacts the display screen.

[0034] Specifically, a part of the connection element 2 is located inside the AR mirror body and is electrically connected to the communication element 1 through the antenna matching circuit; another part of the connection element 2 is located outside the AR mirror body and is electrically connected to the data transmission module 4 of the intelligent educational device such as the learning machine through the interface to form a radio frequency path. It should be noted that in this application, the communication element 1 is connected to the radio frequency path through the connection element 2, so that the AR mirror can be used as an external antenna for intelligent educational devices such as the learning machine.

[0035] Among them, the interface is set at the position where the intelligent educational equipment such as the learning machine contacts the finger mirror.

[0036] Specifically, in this embodiment, the interface is arranged on the top surface of the display screen of the intelligent educational device such as the learning machine, and the interface has a socket corresponding to the connecting element 2 inside, and the connecting element 2 can be directly inserted therein to realize the connection.

[0037] In some possible implementations disclosed in this application, see Figure 2 As shown, at least two communication elements 1 are provided, and the at least two communication elements 1 are arranged opposite to each other.

[0038] It can be understood that, in the present application, by providing at least two communication elements 1, it is possible to enhance signal coverage and receiving capabilities, and improve data transmission rate and reliability.

[0039] Among them, the number of communication elements 1 may be two, three or four, etc., which is not further limited in this embodiment.

[0040] Specifically, in the present embodiment, two communication elements 1 are provided, and the two communication elements 1 are arranged opposite to each other, and can receive and send signals from different directions, thereby expanding the coverage range of the signal and improving the receiving sensitivity and stability of the signal.

[0041] As one implementation mode, two communication elements 1 perform data transmission in parallel; as another implementation mode, two communication elements 1 perform data transmission separately according to different data types.

[0042] Specifically, in this embodiment, one communication element 1 is a WIFI antenna of a 2.4G channel, and the other communication element 1 is a WIFI antenna of a 5G channel. The two communication elements 1 perform data transmission according to different channels.

[0043] In some possible implementations disclosed in this application, see Figure 2 As shown, the connecting element 2 includes a ground pin 21 and a signal pin 22 , four ground pins 21 are provided, and one signal pin 22 is provided.

[0044] It can be understood that in the present application, by setting the connecting element 2 to include four grounding pins 21, a more stable grounding connection can be provided, effectively reducing the impact of electromagnetic interference and noise on the signal transmission of the signal pin 22, thereby improving the integrity and accuracy of the signal; at the same time, the four grounding pins 21 help to quickly release static electricity and protect sensitive components in the circuit from static electricity damage; at the same time, the four grounding pins 21 can make the installation of the connecting element 2 on the circuit board more stable, reducing the looseness of the pins or poor contact due to vibration or external force.

[0045] In the above embodiments, see Figure 2 As shown, two ground pins 21 are located on one side of the signal pin 22 , and another two ground pins 21 are located on the other side of the signal pin 22 .

[0046] It can be understood that in the present application, by setting the ground pin 21 distributed on both sides of the signal pin 22, it helps to distribute the current more evenly around the signal pin 22, reducing local overheating and signal distortion caused by current concentration; at the same time, it can reduce the crosstalk between adjacent signal lines and improve the accuracy and reliability of signal transmission; at the same time, this symmetrical pin layout can make the connecting element 2 more stable when subjected to external forces during installation and use, reducing the possibility of deformation or breakage of the connecting element 2.

[0047] In some possible implementations disclosed in this application, see Figure 2 As shown, the pointer mirror further includes a first magnetic attraction element 3, and the first magnetic attraction element 3 is arranged on the inner side of the surface of the pointer mirror that contacts the intelligent educational device.

[0048] It can be understood that in the present application, by setting a first magnetic element 3 in the pointer mirror, it is possible to adsorb the metal shell of intelligent educational devices such as a learning machine, thereby facilitating the installation and disassembly of the pointer mirror, so that the user can easily and quickly adsorb the pointer mirror on or remove it from intelligent educational devices such as a learning machine, without the need for cumbersome operating steps, thus saving time and energy; at the same time, magnetic adsorption can provide a strong connection force, ensuring that the pointer mirror will not easily fall off or shift during normal use, thereby ensuring the stability of use.

[0049] The first magnetic attraction element 3 may be a magnet made of a strong magnetic material, such as a neodymium iron boron magnet.

[0050] Among them, the first magnetic attraction element 3 is arranged in the AR mirror body, specifically, it is arranged on the inner side of the surface of the AR mirror body that contacts with intelligent educational devices such as learning machines.

[0051] Specifically, two first magnetic elements 3 may be provided, one first magnetic element 3 is provided on one side of the connecting element 2 , and the other first magnetic element 3 is provided on the other side of the connecting element 2 .

[0052] Another aspect of an embodiment of the present application provides an intelligent educational device, including any one of the above-mentioned pointing mirrors.

[0053] Among them, smart educational equipment can be learning machines, tablet computers, etc.

[0054] Specifically, in this embodiment, the intelligent educational device is a learning machine, and the learning mirror is installed on the display screen of the learning machine.

[0055] In some possible implementations disclosed in this application, see Figure 3 As shown, a radio frequency switch 5 is provided on the radio frequency path, and the radio frequency switch 5 is used to switch the signal path.

[0056] It can be understood that in the present application, by setting the RF switch 5 on the RF path, it is possible to switch between different RF frequency bands or working modes, so that intelligent educational devices such as learning machines can adapt to a variety of communication standards and application scenarios.

[0057] Among them, the intelligent educational device such as the learning machine includes a built-in antenna, which is arranged in the metal shell of the intelligent educational device such as the learning machine and is connected to the radio frequency path. That is to say, the intelligent educational device such as the learning machine provided in this embodiment has a built-in antenna and an external antenna connected to the radio frequency path, and the external antenna is a communication element 1 arranged in the pointer.

[0058] Specifically, the output end of the data transmission module 4 on the RF path is provided with a RF switch 5, and the output end of the RF switch 5 is electrically connected to the internal antenna and the external antenna respectively. In this embodiment, the RF switch 5 is used to cut off the internal antenna and the RF path and connect the external antenna and the RF path when receiving a driving signal.

[0059] In the above embodiments, see Figure 3 As shown, the intelligent educational device also includes a sensing element 7, which is arranged on the inner side of the surface of the intelligent educational device in contact with the pointer, and the sensing element 7 is electrically connected to the radio frequency switch 5, and the sensing element 7 is used to sense the magnetic field of the first magnetic attraction element 3.

[0060] It is understandable that in the present application, when the sensing element 7 senses the magnetic field of the first magnetic attraction element 3, it can automatically control the state of the radio frequency switch 5 to achieve more intelligent operation without manual intervention by the user.

[0061] The sensing element 7 may be a Hall switch or other component capable of sensing a magnetic field, which is not further limited in this embodiment.

[0062] Among them, the sensing element 7 is arranged close to the top surface of the display screen of the intelligent educational equipment such as the learning machine, which can more directly sense the approach and connection of the pointer, reduce the interference that may be caused by other internal components, and thus improve the accuracy and sensitivity of the magnetic field sensing of the first magnetic attraction element 3.

[0063] Specifically, when the sensing element 7 is triggered by the magnetic field of the first magnetic attraction element 3, the sensing element 7 sends a driving signal to the RF switch 5, so that the RF switch can cut off the internal antenna and the RF path, and connect the external antenna and the RF path.

[0064] In some possible implementations disclosed in this application, see Figure 3 As shown, an amplifying element 6 is also provided on the radio frequency path, and the amplifying element 6 is located between the data transmission module 4 and the radio frequency switch 5 .

[0065] It can be understood that in the present application, by setting an amplifying element 6 between the data transmission module 4 and the RF switch 5, the RF signal output from the data transmission module 4 can be amplified, and the attenuation of the signal during the transmission process can be compensated, ensuring that the RF signal has sufficient strength to reach the RF switch 5 and finally transmitted to the destination; at the same time, stronger signals can propagate farther distances, expand the effective working range of intelligent educational equipment such as learning machines, and enable the equipment to maintain good communication performance at a longer distance or in a more complex environment.

[0066] The amplifying element 6 includes a power amplifier (PA) and a low noise amplifier (LNA).

[0067] Specifically, the power amplifier is used to enhance the power of the radio frequency signal so that the signal can be effectively transmitted over long distances or through complex channels; the low noise amplifier is used to amplify very weak input signals at the receiving end while minimizing the noise introduced by itself. It can improve the strength and signal-to-noise ratio of the received signal, thereby improving the performance of the receiving system.

[0068] In some possible embodiments disclosed in the present application, the pointer mirror also includes a second magnetic element, the second magnetic element has a magnetic polarity opposite to that of the first magnetic element 3, and the second magnetic element is arranged on the inner side of the surface where the intelligent educational device contacts the pointer mirror.

[0069] It can be understood that in the present application, due to the opposite polarity of the magnetic poles, a strong attraction will be generated between the first magnetic element 3 and the second magnetic element, making the connection between the finger mirror and the intelligent educational equipment such as the learning machine more stable and not easy to loosen or fall off during use; at the same time, the mutual attraction of opposite magnetic poles can guide the finger mirror to quickly and accurately adsorb to the corresponding position of the intelligent educational equipment such as the learning machine, thereby improving the user's efficiency and experience.

[0070] The second magnetic attraction element may also be a neodymium iron boron magnet.

[0071] Specifically, two second magnetic elements are provided, and the two second magnetic elements are provided in one-to-one correspondence with the two first magnetic elements 3 , one second magnetic element is provided on one side of the interface, and the other second magnetic element is provided on the other side of the interface.

[0072] An embodiment of the present application provides a pointer mirror and an intelligent educational device, wherein the pointer mirror is provided with a communication element 1 electrically connected to a data transmission module 4 of the intelligent educational device, so that the pointer mirror can be used as an external antenna of the intelligent educational device, thereby improving signal strength and expanding signal coverage.

[0073] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0074] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
