Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of teaching equipment, and more specifically, it relates to a multimodal teaching device for English teaching. Background Art
[0002] In the vast field of English teaching, the traditional teaching mode has long dominated. However, its inherent limitations have gradually emerged when facing diverse learning needs. Especially when targeting two special learning groups, namely the visually impaired and young children, traditional teaching methods are difficult to fully play their roles, and there is an urgent need for innovative teaching devices to fill the gap.
[0003] For the visually impaired, the road to English learning is full of thorns. Traditional English teaching highly relies on visual presentation. Whether it is the blackboard writing, the text in textbooks, or the content shown in multimedia courseware, the visually impaired are difficult to access. By relying solely on auditory learning of English, they cannot intuitively feel the shapes of English letters and are difficult to establish an effective connection between letters and pronunciations, resulting in low learning efficiency, a boring and difficult learning process. At the same time, in the learning of word spelling, unlike normal people who can remember the letter combinations of words by observation, they can only mechanically repeat the memory, and the forgetting rate is extremely high. This teaching situation greatly limits the improvement of the English level of the visually impaired and hinders their integration into a broader knowledge world.
[0004] As a new group in English learning, young children are in the golden enlightenment stage of language learning. They are characterized by strong curiosity, dominant image thinking, and easy distraction of attention. Traditional English teaching methods often adopt an indoctrination approach, mainly focusing on a large number of word memorizations and grammar explanations, with a single and boring form. Young children are difficult to concentrate for a long time, and their interest in English learning is gradually worn away in this monotonous teaching. Moreover, traditional teaching lacks rich context creation and physical object display, and cannot fully mobilize the multiple senses of young children to participate in learning, making it difficult to meet their needs of being curious about the world and eager to learn knowledge through personal experience. This may cause young children to have a resistant attitude towards English at the initial stage of English learning, which is not conducive to the long-term development of their subsequent English learning path.

[0067] Connecting components, there are at least two connecting components, the connecting components are arranged on the transmission belt 12, and the three-dimensional English letter 4 is fixedly connected to the connecting components.
[0068] The driving mechanism further includes a fixing plate 13, the fixing plate 13 is horizontally fixedly connected to the inner side wall of the cabinet 1, the upper surface of the fixing plate 13 is fixedly connected with a first electric telescopic rod 14, the moving end of the first electric telescopic rod 14 is fixedly connected with a push block 15, and the push block 15 is slidably connected to the fixing plate 13.

[0070] At least two annular grooves 20 are formed in the connecting shaft 10, an annular limiting plate 21 is fixedly connected to the inner ring wall of the belt roller 11, and the annular limiting plate 21 is rotatably connected in the annular groove 20.
[0071] At least two limiting cavities 22 are formed in the connecting shaft 10, a first spring 23 is fixedly connected to the side wall of the limiting cavity 22, a limiting bead 24 is fixedly connected to the end of the first spring 23, the end of the limiting bead 24 away from the first spring 23 passes through the side wall of the limiting cavity 22 and is inserted into the inner ring wall of the annular limiting plate 21, the limiting bead 24 is used to increase the rotation resistance of the belt roller 11, a groove is formed in the inner ring wall of the annular limiting plate 21, and the end of the limiting bead 24 away from the first spring 23 is inserted into the groove. By restricting the annular limiting plate 21 with the limiting bead 24, during the process of the first driving motor 16 stopping driving the belt roller 11 to rotate, the belt roller 11 can be prevented from rotating due to the gravity of the three-dimensional English letter 4 on the transmission belt 12.
[0072] The connecting component includes a first fixing block 25, the longitudinal section of the first fixing block 25 is U-shaped, and there are at least two first fixing blocks 25 which are equidistantly and fixedly connected to the transmission belt 12.

The three-dimensional English letter 4 is fixedly connected to the connecting block 26. A torsion spring is sleeved on the rotating shaft 27. One end of the torsion spring is fixedly connected to the connecting block 26, and the other end of the torsion spring is fixedly connected to the first fixing block 25. When the torsion spring is in the natural state, the three-dimensional English letter 4 is perpendicular to the first fixing block 25, that is, when the two connecting blocks 26 are located at the upper end of the transmission belt 12, the three-dimensional English letter 4 is in a vertical state and located above the first fixing block 25.
[0074] The control mechanism includes a push plate 28. The push plate 28 is slidably connected to the cabinet 1. The end of the push plate 28 cooperates with the three-dimensional English letter 4 at the upper end of the transmission belt 12. When the end of the push plate 28 contacts the side wall of the three-dimensional English letter 4, during the process of the transmission belt 12 driving the three-dimensional English letter 4 to move towards the push plate 28, by the blocking of the push plate 28 on the three-dimensional English letter 4, the upper end of the three-dimensional English letter 4 is tilted downward. When the transmission belt 12 drives the three-dimensional English letter 4 to move to directly above the transmission belt 12, the three-dimensional English letter 4 is flush with the upper surface of the first fixing block 25, so as to control the display quantity of the three-dimensional English letter 4 through the blocking of the push plate 28 on the three-dimensional English letter 4.
[0075] A push rod 29 is vertically and fixedly connected to the lower surface of the push plate 28. A second spring 30 is fixedly connected to the side wall of the push rod 29. One end of the second spring 30 is fixedly connected to the inner side wall of the cabinet 1. The natural state of the second spring 30 is an extended state, and the elastic force value when the second spring 30 is extended is greater than the rotational force value of the torsion spring. During the process of the push plate 28 pushing the three-dimensional English letter 4 to the side, it is avoided that the three-dimensional English letter 4 reversely pushes the push plate 28 through the rotational force of the torsion spring.

The second electric telescopic rod 31 is connected to the display screen 3 through a signal. When an English word is displayed on the display screen 3, the display screen 3 can control the expansion and contraction of the second electric telescopic rod 31 through the background central processing unit, so as to control the length of the second electric telescopic rod 31 extended according to the number of English letters in the English word displayed on the display screen 3, that is, the number of times the second electric telescopic rod 31 pushes the push plate 28 away from the three-dimensional English letter 4 through the trapezoidal block 32, thereby controlling the number of three-dimensional English letters 4 erected for display.
[0077] The stop rod 33 is a telescopic rod, and the side wall of the stop rod 33 is flush with the small end surface of the trapezoidal block 32, and the stop rod 33 is matched with the push rod 29.

A sliding rod is fixedly connected to the lower surface of the stop rod 33, and the lower end of the sliding rod is slidably connected in the strip-shaped chute. The stop rod 33 is supported by the sliding rod, so as to facilitate the second electric telescopic rod 31 to drive the multiple stop rods 33 to expand and contract.
[0078] The article display mechanism includes symmetrically arranged fixed shafts 34. The fixed shafts 34 are fixedly connected to the inner side wall of the cabinet 1.

[0080] At least two second fixing blocks 43 are fixedly connected to the conveyor belt 36. The second fixing blocks 43 are used for fixing the display articles. Articles to be displayed, such as hard dolls injection-molded by the prior art, are fixed to the second fixing blocks 43 through glue or straps, so as to facilitate the conveyor belt 36 to drive the articles to be displayed to move upward through the second fixing blocks 43.
[0081] A baffle plate 44 is fixedly connected to the inner side wall of the cabinet 1. The baffle plates 44 are symmetrically arranged with respect to the driving mechanism, and one of the baffle plates 44 is located between the driving mechanism and the article display mechanism.
[0082] One side of the cabinet 1 is open.

A cabinet door 42 is rotatably connected to the side wall of the open end of the cabinet 1.
[0083] Working principle: When it is necessary to recognize and learn English letters, the second electric telescopic rod 31 is activated. The mobile end of the second electric telescopic rod 31 pushes the trapezoidal block 32 forward. The trapezoidal block 32 pushes the push rod 29 in contact with it away from the three-dimensional English letter 4 through the inclined surface, so that the end of the push plate 28 close to the three-dimensional English letter 4 is flush with the side wall of the first display opening. At this time, a group of three-dimensional English letters 4 corresponding to the push plate 28 are released from the restriction of the push plate 28, and the second spring 30 connected to the cover push plate 28 is in a contracted state. Then, the first electric telescopic rod 14 is activated. The mobile end of the first electric telescopic rod 14 pushes the push block 15 and the first driving motor 16 forward. When the position of the first gear 17 corresponds to the position of the trapezoidal block 32, the first gear 17 meshes with the meshing teeth 18 on one of the belt rollers 11. Then, the first driving motor 16 is started. The output shaft of the first driving motor 16 drives the first gear 17 to rotate at a set speed. The teeth of the first gear 17 are accurately meshed with the evenly distributed meshing teeth 18 on the circumferential wall of one of the belt rollers 11. The rotational torque of the first gear 17 is transmitted to the belt roller 11, driving the belt roller 11 to start rotating around the connecting shaft 10. During the rotation of the belt roller 11, the end of the limiting bead 24 is pushed by the inner wall of the annular limiting plate 21, so that the limiting bead 24 is squeezed into the interior of the limiting cavity 22. When the groove on the annular limiting plate 21 corresponds to the position of the limiting bead 24, due to the stretching force of the first spring 23, the first spring 23 pushes the limiting bead 24 into the groove, facilitating the clamping of the limiting bead 24 into the groove. Since the belt roller 11 is rotatably connected to the connecting shaft 10, when the first driving motor 16 drives one of the belt rollers 11 to rotate, the belt roller 11 not meshed with the first gear 17 on the first driving motor 16 is in a stationary state. When the transmission belt 12 starts to circulate under the action of friction, with the operation of the transmission belt 12, the connecting component drives the three-dimensional English letter 4 to move along a specific trajectory. When the three-dimensional English letter 4 moves to directly above the transmission belt 12 along with the transmission belt 12, the scanner 5 scans the erected three-dimensional letter and transmits the scanning result to the display screen 3 for display through the display screen 3. At the same time, the pronunciation of the letter is played through the voice announcer 7, facilitating the visually impaired to learn the pronunciation of the letter. At the same time, the visually impaired can touch the shape of the erected letter with their hands and combine the voice played by the voice announcer 7 to memorize the letter, facilitating the visually impaired to learn English letters and become familiar with the shapes of English letters.
[0084] When visually impaired persons need to learn English words based on the displayed items, the teacher first opens the cabinet door 42 of the cabinet 1, places the teaching items to be displayed on the conveyor belt 36 of the item display mechanism, and firmly fixes the items using the second fixing block 43. At the same time, according to the teaching plan, initial settings are made for the drive mechanism, control mechanism, etc. in the cabinet 1, such as adjusting the initial rotation speed of the first drive motor 16, setting the initial contraction state of the second electric telescopic rod 31, etc. After the settings are completed, the cabinet door 42 is closed to ensure that the device is in a ready state.
[0085] During the teaching process, the third electric telescopic rod 37 is started. The mobile end of the third electric telescopic rod 37 pushes the second drive motor 39 forward. When the second gear 40 meshes with the tooth groove 41 on one of the rotating rollers 35, the second drive motor 39 is started. The second drive motor 39 drives the rotating roller 35 to rotate through the meshing of the second gear 40 and the tooth groove 41. When the rotating roller 35 drives one of the items to be displayed to move to directly above the conveyor belt 36 through the conveyor belt 36, the second drive motor 39 stops operating at this time. The item displayed directly above the conveyor belt 36 is displayed through the second display port. At this time, the camera on the side of the display port transmits the captured picture of the displayed item to the display screen 3, and the English name of the item is displayed on the display screen 3. Then, the pronunciation of the English name is broadcast through the voice broadcaster 7. At the same time, the display screen 3 controls the first electric telescopic rod 14, the second electric telescopic rod 31, and the scanner 5 to start. The second electric telescopic rod 31 pushes the trapezoidal block 32 forward, and the display screen 3 controls the extension length of the second electric telescopic rod 31 according to the number of English letters in the English name displayed on it. For example, if the English name displayed on the display screen 3 contains 4 English letters, the second electric telescopic rod 31 drives the trapezoidal block 32 to move to the side of the fourth push plate 28 through the first push plate 28, and the trapezoidal block 32 pushes the first push plate 28 to the fourth push plate 28 away from the three-dimensional English letter 4 in the reverse direction through the inclined surface of the trapezoidal block 32, thereby realizing the control of the number of displayed three-dimensional English letters 4.
[0086] The first electric telescopic rod 14 pushes the first driving motor 16 forward through the pushing block 15. When the first gear 17 meshes with the meshing teeth 18 on the first belt roller 11, at this time, the first driving motor 16 drives the first belt roller 11 to rotate through the first gear 17, thereby driving the first group of three-dimensional English letters 4 to rotate. The scanner 5 transmits the scanning information of the three-dimensional English letters 4 above the transmission belt 12 to the display screen 3. When the scanner 5 scans that the three-dimensional English letters 4 directly above the transmission belt 12 correspond to the first letter in the English name displayed on the display screen 3, the first driving motor 16 stops rotating. At the same time, the first electric telescopic rod 14 continues to push the first driving motor 16 forward through the pushing block 15. When the first gear 17 meshes with the meshing teeth 18 on the second belt roller 11, the first driving motor 16 is started. The first driving motor 16 drives the second belt roller 11 to rotate through the first gear 17. When the scanner 5 scans that the three-dimensional English letters 4 above the second transmission belt 12 correspond to the second letter in the English name displayed on the display screen 3, the first driving motor 16 stops rotating again, and the first electric telescopic rod 14 continues to push the first driving motor 16 in the direction of the third belt roller 11, and so on. Thus, through the cooperation of multiple groups of three-dimensional English letters 4, the English name and English words displayed on the display screen 3 are spelled out. At this time, the visually impaired person can touch the displayed items with their hands, and at the same time touch multiple groups of three-dimensional English letters 4 with their hands, and memorize the spelled English words, and then practice the pronunciation of the English word according to the voice broadcast by the voice broadcaster 7, realizing the linkage display of multi-modal teaching content and enhancing the teaching effect.
[0087] When a visually impaired patient needs to spell an English word they have learned, the second electric telescopic rod 31 is activated at this time. The second electric telescopic rod 31 pushes the trapezoidal block 32 forward. When the trapezoidal block 32 pushes the push plate 28 away from the three-dimensional English letter 4 through the push rod 29, when the second electric telescopic rod 31 is fully extended, the ends of each push plate 28 are flush with the side wall of the first display opening at this time. When the three-dimensional English letter 4 is separated from the extrusion of the push plate 28, due to the rotational force of the torsion spring, the torsion spring drives the connecting block 26 and the three-dimensional English letter 4 to rotate upward, making the three-dimensional English letter 4 perpendicular to the first fixed block 25. At the same time, the first electric telescopic rod 14 is activated. The moving end of the first electric telescopic rod 14 pulls the first drive motor 16 back through the push block 15. When the first electric telescopic rod 14 is in a fully contracted state, the first gear 17 disengages from the first belt roller 11. At this time, the visually impaired person manually pushes the three-dimensional English letter 4 directly above the transmission belt 12 downward, driving the rotation of the transmission belt 12, and recognizing the three-dimensional English letter 4 through the touch of the hand. When the visually impaired person touches and drives the first group of three-dimensional English letters 4 to be the required letters, the visually impaired person can identify the second group of three-dimensional English letters 4. When the visually impaired person touches the three-dimensional English letter 4 directly above the second transmission belt 12 to be the required letter, the third group of English letters can be screened and identified at this time, so as to screen out the three-dimensional English letters 4 in the English word to be spelled. By touching and identifying and screening multiple groups of three-dimensional English letters 4, and spelling the corresponding English word through the three-dimensional English letters 4, the spelling of English words by visually impaired people is realized, and it helps visually impaired patients to remember English words.
[0088] When the visually impaired patient has completed the spelling of the corresponding English word, due to the limiting beads 24 in the limiting cavity 22 being tightly inserted into the inner ring wall of the annular limiting plate 21 under the elastic force of the first spring 23, an additional static resistance is provided for the belt roller 11 to ensure that it will not rotate randomly when not driven by an external force. And the scanner 5 scans the spelled three-dimensional English letters 4 and transmits the scan information to the display screen 3, and then displays it through the display screen 3. At the same time, the voice announcer 7 makes a voice broadcast of the spelled three-dimensional English letters 4, and corrects the wrongly spelled parts at the same time, so as to deepen the memory of the visually impaired person for this word. From multi-modal angles such as hearing and physical display, a comprehensive and three-dimensional English learning experience is provided for the visually impaired person, greatly enhancing the learning effect and improving the learning enthusiasm and participation of students.
[0089] And through the display of physical objects, it also improves the interest of children in English learning, and from multi-modal angles such as vision, hearing, and physical display, a comprehensive and three-dimensional English learning experience is provided for children, greatly enhancing the learning effect and improving the learning enthusiasm and participation of students.
