[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 The teaching picture hanging display device in this embodiment includes a main frame 1 and a folding writing board 2. The folding writing board 2 is hinged to both the left and right sides of the main frame 1. A rewind box 3 is fixedly installed at the bottom inside the main frame 1. A flexible screen display and storage mechanism 4 is provided inside the rewind box 3.

[0022] The flexible screen display and storage mechanism 4 includes a servo motor 401, bearings 402, and fixing plates 406. Two bearings 402 are fixedly installed inside the winding box 3. One servo motor 401 and two sets of fixing plates 406 are fixedly installed inside the main frame 1, with two fixing plates in each set. A transmission rod 403 connected to the output end of the servo motor 401 is fixedly installed on the inner wall of each of the two bearings 402. A winding roller 404 is fixedly installed on the transmission rod 403, and an electronic wall chart display screen 405 extending into the interior of the main frame 1 is fixedly connected to the winding roller 404. The electronic wall chart display screen 405 uses a flexible e-ink screen with high resolution and a good viewing angle. The screen can connect to the teacher's teaching equipment via Bluetooth or Wi-Fi, facilitating the transmission of wall chart image data from different historical periods. The top of the rewind box 3 has a storage slot adapted to the electronic wall chart display screen 405. When not in use, the screen can be rolled up and stored in the storage slot at the bottom of the frame. When the electronic wall chart display screen 405 needs to be stored, the servo motor 401, bearing 402, and transmission rod 403 work together to drive the rewind box. The winding roller 404 rotates stably. Guide rods 407 are fixedly installed on both sets of fixed plates 406. Movable plates 408 are slidably connected to the two guide rods 407. The bottom of the movable plate 408 is fixedly connected to the top of the electronic wall chart display screen 405. Two negative-pole magnets 409 are fixedly installed on the top of the movable plate 408. A push-pull groove 410 is provided on the front side of the movable plate 408. The design of the push-pull groove 410 makes it easier and less strenuous for the user to unfold the electronic wall chart display screen 405. Then, while the winding roller 404 rotates stably, it not only... The negative magnet 409 at the top of the display screen 405 will separate from the positive magnet 101 on the main frame 1. The bottom of the display screen will also be slowly retracted by the stable rotation of the winding roller 404. Finally, by setting the fixing plate 406 and the guide rod 407, the electronic wall chart display screen 405 can maintain a high degree of flatness during the retraction process, which can effectively reduce the impact of creases after retraction. Thus, this mechanism can not only effectively retract the display screen, but also make it easier to carry after retraction, and the retracted display screen can effectively isolate external influences.

[0023] In the implementation of the case, two positive magnets 101 that are compatible with the negative magnet 409 are fixedly installed on the inner top wall of the main frame 1. By setting the negative magnet 409 and the positive magnet 101, the stability of the electronic wall chart display screen 405 can be effectively maintained when it is unfolded, making it convenient for people to view.

[0024] In the implementation of the case, animation and sound module power supplies 5 are installed on both the left and right sides of the main frame 1. The animation and sound module power supply 5 is composed of a small speaker and an animation display chip. When displaying a specific historical event or figure poster, it can play related animated video clips, accompanied by voice explanation, background music or sound effects, to enhance the intuitiveness and fun of teaching. A dust filter 6 is installed on the main frame 1 and in front of the animation and sound module power supply 5. The dust filter 6 can completely prevent dust from entering the equipment, ensuring the normal operation of the equipment and extending its service life.

[0025] In the implementation of the case, an installation slot is provided on the main frame 1 above the dust filter 6 on the left side. The installation slot contains a controller 7, which includes a power switch, volume control, a previous / next picture switching button, and an animation playback pause button. These buttons are electrically connected to the electronic components in this patent via wires, making it convenient for teachers to operate during the teaching process.

[0026] In the implementation of the case, a hanging ring 8 is fixedly installed on the top of the main frame 1, which facilitates the overall suspension of the device.

[0027] When implementing this procedure, please follow these steps:

[0028] 1) First unfold the two folding writing boards 2 and hang them in a suitable location in the classroom;

[0029] 2) Then turn on the power to the electronic wall chart display screen and the animation and sound module 5;

[0030] 3) Then, select the historical posters to be displayed using the teaching equipment and send them to the electronic poster display screen 405. At the same time, according to the teaching progress, click the control button to play animations and sounds.

[0031] 4) Finally, turn off controller 7, and store the electronic poster display screen 405 in the recycling box 3. Then fold the two writing boards and store or carry them to the next teaching location.

[0032] In summary, this teaching chart hanging display device, through the flexible screen display and storage mechanism 4, allows the electronic chart display screen 405 to be stored when needed. Firstly, the servo motor 401, bearing 402, and transmission rod 403 work together to drive the winding roller 404 to rotate stably. Then, as the winding roller 404 rotates stably, not only does the negative magnet 409 at the top of the electronic chart display screen 405 separate from the positive magnet 101 on the main frame 1, but the bottom of the display screen also slowly retracts due to the stable rotation of the winding roller 404. Finally, by setting a fixing plate 406 and a guide rod 407, the electronic chart display screen 405 maintains high flatness during storage, effectively reducing creases after storage. Therefore, this mechanism not only effectively stores the display screen but also makes it easier to carry after storage. Furthermore, the stored display screen effectively isolates it from external influences, solving the problem that the electronic display screen in this patent is directly exposed to the outside of the device, making it highly susceptible to damage.
