[0080] The smart mobile terminal 7 can use wireless communication technology to connect to the Internet, so that it can search, download, preview or display digitized images and / or videos on the network, obtain digitized images and / or videos, and transmit the data content containing the images and / or videos to the display module 6 through the communication module 12. The display module 6 displays the images and / or videos for learners to copy; the data transmission technology used by the smart mobile terminal 7 on the display module 6 includes but is not limited to screen projection, split screen, sharing, etc.

[0081] Combination Figure 2As shown, in some embodiments, a power module 11 and a communication module 12 are arranged in the cavity of the base box 1; the power module 11 includes but is not limited to a battery, the power module 11 is electrically connected to the power-consuming electronic devices of the calligraphy auxiliary learning device and provides power, and the power module 11 can be charged through the power and data interface 14, and can also be charged wirelessly.

[0082] The communication module 12 is one of a Bluetooth module, a WiFi module, and an NFC module. The communication module 12 is connected to the smart mobile terminal 7 for communication. The information transmission between the smart mobile terminal 7 and the communication module 12 can be transmitted by wire through the power supply and data interface 14, or can be transmitted wirelessly through wireless communication protocols such as Bluetooth.

[0083] Combination Figure 2 and Figure 3 As shown, the grid module 4 includes a plurality of grid modules 41, a control motor drive board 42, and a grid wiring assembly 43; the grid modules 41 are fixedly installed in the container box 3, and are arranged one by one with the emission windows 31; the control motor drive board 42 is arranged in the base box 1, and is electrically connected to the power module 11 and the communication module 12 respectively; the grid wiring assembly 43 is arranged in the riser 2; the grid wiring assembly 43 is electrically connected to the control motor drive board 42 and the grid module 41 respectively.

[0084] Through the above arrangement, the calligraphy auxiliary learning device of this embodiment can use the grid module 4 to project the writing grid in the writing area 001, and can use the control motor drive board 42 to control and adjust the specifications of the writing grid.

[0085] In some possible implementations, the shape, size, brightness and other information of the writing grid that can be set on the smart mobile terminal 7 are transmitted to each grid module 41 through the communication module 12 and the control motor drive board 42, and each grid module 41 is controlled to emit laser to project into the writing area 001 to form a writing grid, and can be adjusted in real time on the smart mobile terminal 7.

[0086] In this embodiment, the specifications, size, color of the laser, brightness of the laser and other parameters of the grid can be set on the smart mobile terminal 7, and then transmitted to the communication module 12 and the control motor drive board 42 with one click, and finally transmitted to the grid module 41 for execution.

[0087] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the grid module 41 includes a housing 411 , a rotating shaft 412 , a gear 413 , a control motor 414 and a laser tube 415 .

[0088] The rotating shaft 412 is rotatably connected to the housing 411 , the gear 413 is fixedly connected to the rotating shaft 412 , the laser tube 415 is fixedly mounted on the rotating shaft 412 , the control motor 414 is fixedly mounted on the housing 411 , and the control motor 414 includes a motor gear shaft 4141 , which is meshed with the gear 413 .

[0089] The laser tube 415 can emit laser light through the emission window 31 to project grid lines of a preset writing grid in the writing area 001 .

[0090] Different scenarios have different requirements for the specifications and sizes of the writing grid. The motor gear shaft 4141 transmits the rotation to the rotating shaft 412 through the gear 413. The rotation of the rotating shaft 412 drives the laser tube 415 to swing at a preset angle. The grid spacing in the writing grid on the writing area 001 is adjusted by adjusting the inclination angle of the laser emitting tube 31.

[0091] In some possible implementations, the control motor 414 is a stepper motor or a servo motor; the wiring of the control motor 414 and the laser tube 415 are collectively referred to as a grid wiring assembly 43 .

[0092] In some embodiments, the number of the grid modules 41 is determined according to the number of writing grids on the writing area 001. In other embodiments, the laser emitted by the laser tube 415 has multiple brightness and multiple colors to choose from.

[0093] Exemplarily, the diameter of the gear 413 should be much larger than the motor gear shaft 4141 so as to more accurately control the swing angle of the laser tube 415 .

[0094] Combination Figure 2 and Figure 3 As shown, in some embodiments, the camera module 5 includes a camera 51 , a camera driving board 52 and a camera cable assembly 53 .

[0096] The camera drive board 52 is arranged in the cavity of the base box 1, and the camera drive board 52 is electrically connected to the power module 11 and the communication module 12 respectively; the camera cable assembly 53 is arranged in the cavity of the vertical pipe 2; the camera cable assembly 53 electrically connects the camera drive board 52 with the camera 51.

[0097] Through the above arrangement, the camera operation can be performed on the smart mobile terminal 7, and the video can be transmitted to the camera module 5 through the communication module 12; specifically, the camera 51 can collect the work image and / or writing video in the writing area 001 through the transmitting window 31, and can be transmitted to the smart mobile terminal 7 to save the digital data. In addition, when the smart mobile terminal 7 is connected to the Internet, the smart mobile terminal 7 can be used to communicate with each other on the Internet, appreciate and even conduct real-time interactive teaching activities on the Internet.

[0098] In some possible implementations, when multiple smart mobile terminals 7 are not connected to the Internet, they can be connected through a local area network communication to conduct small-scale calligraphy classroom teaching, or one smart mobile terminal 7 can control several calligraphy auxiliary learning devices to create a digital calligraphy classroom and conduct digital calligraphy teaching activities.

The electronic ink display screen only displays a few colors such as black and white, and only refreshes and consumes electricity when the copybook content on the display panel 61 needs to be updated. Therefore, it is very power-saving and can also extend the service life of the display panel 61. The display effect is close to that of a paper copybook, does not hurt the eyes, and is particularly suitable for being a display screen for calligraphy copybooks.

[0104] In some embodiments, the length of the display panel 61 ranges from 210 mm to 297 mm, and the width of the display panel 61 is less than half of the length L.
