[0002] With the rapid development of information technology, the traditional English teaching mode has been difficult to meet the needs of modern education for diversification, interactivity, and high efficiency. Traditional English teaching mainly relies on blackboards, textbooks, and teachers' oral explanations. This single teaching mode lacks intuitiveness and interactivity, is difficult to stimulate students' learning interests, and cannot fully adapt to the learning styles and ability differences of different students.

[0003] The volume of existing multimodal English teaching devices is generally set to be relatively large, making them inconvenient to move and carry, and not conducive to teaching. The display screens of existing multimodal English teaching devices are generally exposed externally, which is not only easy to be damaged but also accumulates dust that is difficult to clean, affecting the visual effect; moreover, the interactive effect of existing English multimodal teaching devices is poor, and it is not convenient to adjust the angle of the touch screen, making it relatively inconvenient to use. Therefore, we propose a multimodal English teaching device for English teaching. Summary of the Invention

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1 and Figure 2 , the present invention provides a technical solution: a multimodal English teaching device for English teaching, including two U-shaped installation boxes 1, and the two U-shaped installation boxes 1 are symmetrically arranged. Fixed plates 3 are fixedly connected to the top and bottom between the two U-shaped installation boxes 1, and a display screen 2 is arranged in the U-shaped installation box 1 in a lifting and matching manner.

[0026] At the bottom of the two U-shaped installation boxes 1, there is a linkage lifting mechanism 4 for driving the lifting of the two display screens 2. The surface of the U-shaped installation box 1 is connected with a sealing cover plate 5 in a matching manner, and the bottom end of the sealing cover plate 5 is rotatably connected to the bottom end of the U-shaped installation box 1. Between the two fixed plates 3, there is a connection adjustment mechanism 6 for driving the rotation of the two sealing cover plates 5. An installation plate 7 with an adjustable angle is arranged on one side of the sealing cover plate 5 located in the U-shaped installation box 1, and a touch screen 8 is embedded on the surface of the installation plate 7. Speakers 30 are installed at the top of the two U-shaped installation boxes 1.

[0027] It should be noted that when the sealing cover plate 5 is connected to the U-shaped installation box 1, the sealing cover plate 5 shields the display screen 2, avoiding the collision of external objects on the display screen 2. Through the setting of the connection adjustment mechanism 6, the lifting adjustment of the two display screens 2 can be controlled simultaneously. Through the touch screen 8, it is convenient for the instructor to operate. Through the setting of the speakers 30, it is convenient to amplify the sound, so that students can hear the content clearly. By integrating the display screen 2, the touch screen 8 and the speakers 30, multimodal interaction of vision, touch and hearing is realized, enhancing the immersion and interactivity of English teaching and improving the learning effect.

[0028] Please refer to Figure 2 and Figure 4 Figure 2 and Figure 4 , the linkage lifting mechanism 4 includes a bidirectional lead screw 10. The bottom end inside the U-shaped mounting box 1 is rotatably connected to the bidirectional lead screw 10 through a bearing. The two ends of the bidirectional lead screw 10 are symmetrically threadedly connected with sliders 11. The top ends of the sliders 11 are rotatably connected to support rods 12. Connecting blocks are arranged at both ends of the bottom of the display screen 2. The end parts of the two support rods 12 are respectively rotatably connected to the two connecting blocks. The end parts of the two bidirectional lead screws 10 respectively pass through the two U-shaped mounting boxes 1 and are fixedly connected with driven gears 21. A mounting block 18 is fixedly installed at the bottom end between the two U-shaped mounting boxes 1, and a driving motor 19 is fixedly installed at the bottom of the mounting block 18. The end of the output shaft of the driving motor 19 is fixedly connected with a driving gear 20. Both driven gears 21 are meshed and connected with the driving gear 20.

[0029] It should be noted that when it is necessary to adjust the height of the display screen 2, by controlling the driving motor 19 to work, the driving gear 20 can be driven to rotate. Through the meshing connection between the two driven gears 21 and the driving gear 20, the bidirectional lead screw 10 rotates. Through the threaded connection between the sliders 11 at both ends of the bidirectional lead screw 10 and it, the two sliders 11 move away from each other. Under the action of the support rods 12, the position of the display screen 2 rises, so that the height of the display screen 2 can be adjusted according to needs, making it convenient for the lecturer to watch the display screen 2 when standing beside the blackboard and also convenient for the students in their seats to watch the other display screen 2.

[0030] Please refer to Figure 2 and Figure 3 Figure 2 and Figure 3 , the connection adjustment mechanism 6 includes a lifting lead screw 13. The two fixing plates 3 are rotatably connected to the lifting lead screw 13 through a bearing. A servo motor 14 is fixedly installed at the top of the fixing plate 3 at the top of the U-shaped mounting box 1, and the end of the output shaft of the servo motor 14 passes through the fixing plate 3 and is fixedly connected with the lifting lead screw 13. An H-shaped lifting rod 15 is threadedly connected to the outside of the lifting lead screw 13. The H-shaped lifting rod 15 is slidably connected between the two U-shaped mounting boxes 1. Four end parts of the H-shaped lifting rod 15 are rotatably connected with connecting rods 16. One side of the closed cover plate 5 away from the U-shaped mounting box 1 is slidably connected with a U-shaped sliding rod 17. The four connecting rods 16 at the end parts of the H-shaped lifting rod 15 are respectively rotatably connected to the two end parts of the two U-shaped sliding rods 17.

[0031] It should be noted that by controlling the servo motor 14 to work to drive the lifting lead screw 13 to rotate, through the threaded connection between the H-shaped lifting rod 15 and the lifting lead screw 13, the H-shaped lifting rod 15 moves downward. Under the action of the connecting rods 16, the closed cover plates 5 on the two U-shaped mounting boxes 1 are unfolded. The two closed cover plates 5 support on the tabletop, and one of the display screens 2 on the U-shaped mounting box 1 can be faced to the students, and the other display screen 2 can be faced to the lecturer, facilitating the interaction between teachers and students.

[0032] Please refer to Figure 2 and Figure 6 As shown in Figure 2 and Figure 6 , a connecting plate 28 is symmetrically and fixedly connected to the top between two U-shaped mounting boxes 1. One end of the connecting plate 28 is integrally connected with a rotating shaft 29 where a loudspeaker 30 is located. The rotating shaft 29 is rotatably connected between the two connecting plates 28 in a matching manner. A fastening knob 31 is arranged at the top of the connecting plate 28. The end of the rotating shaft 29 is provided with fastening holes at equal intervals, and the end of the fastening knob 31 is threadedly connected inside the fastening holes.

[0033] It should be noted that during the use of the present invention, in the initial state, the whole device resembles a handbag and can be carried by hand by pulling the handle 9. When in use, the U-shaped mounting box 1 is placed at the podium of the classroom. The control system of the device is used to control the servo motor 14 to work and drive the lifting lead screw 13 to rotate. Due to the threaded connection between the H-shaped lifting rod 15 and the lifting lead screw 13, the H-shaped lifting rod 15 moves downward. Under the action of the connecting rod 16, the closing covers 5 on the two U-shaped mounting boxes 1 are unfolded. The two closing covers 5 support on the tabletop. One of the display screens 2 on the U-shaped mounting box 1 can face the students, and the other display screen 2 can face the lecturer. By controlling the driving motor 19 to work, the driving gear 20 can be driven to rotate. Due to the meshing connection between the two driven gears 21 and the driving gear 20, the bidirectional lead screw 10 rotates. Due to the threaded connection between the sliders 11 at both ends of the bidirectional lead screw 10 and it, the two sliders 11 move away from each other. Under the action of the support rod 12, the position of the display screen 2 rises. The setting of the two display screens 2 is convenient for students and teachers to watch respectively. The lecturer can rotate the adjustment knob 27 to make the threaded rod 23 rotate. Due to the threaded connection between the sliding seat 24 and the threaded rod 23, the threaded rod 23 moves. Under the action of the adjustment rod 25, the mounting plate 7 is unfolded. At this time, it is convenient for the lecturer to operate the touch screen 8 for explanation. The lecturer can loosen the fastening knob 31, then rotate the loudspeaker 30 to make the loudspeaker 30 face the students, and then tighten the fastening knob 31 to facilitate the students to hear the sound. When the students have difficult problems and come to the podium to ask questions, the lecturer can make the students behind him clearly watch the display screen 2 while operating the touch screen 8, and at the same time, it can also be shown to the students at the seats through the other display screen 2, which is convenient for unified explanation of difficult problems and enhances the interaction effect between teachers and students.
