Description

Technical Field

[0001] This invention belongs to the field of teaching demonstration technology, specifically a demonstration device for vocational English teaching. Background Technology

[0002] English teaching in secondary vocational schools refers to English teaching activities that take students in secondary vocational schools as the teaching object, aim at both career development needs and the improvement of basic cultural literacy, and integrate general English knowledge with vocational English skills. It is an important part of the public basic course teaching in the secondary vocational education system and has three core characteristics: basic, vocational and practical.

[0003] However, existing technologies often have the following drawbacks: When displaying cards on a display device, lights need to be lit around the cards to make the words on the card surface clearer. However, the required lighting varies depending on the surrounding environment. Most existing lights are set to a uniform brightness and cannot adjust the brightness according to the natural light intensity of different usage environments such as exhibition halls, outdoor spaces, indoor shopping malls, and exhibitions. They can only achieve a relatively clear viewing effect under a certain fixed lighting environment. Once the display scene is changed, the lighting effect immediately fails, reducing the scene adaptability of the device.

[0004] Therefore, the present invention provides a display device for English teaching in secondary vocational schools. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

The display mechanism includes a magnetic rail, the outside of which is embedded in the inside of the track groove. Magnetic blocks are magnetically attracted to the surface of the magnetic rail, and a card plate is fixedly connected to one end of each magnetic block. An illumination lamp is embedded in the inner wall of the card plate.

[0007] As a preferred technical solution of the present invention, a plurality of sensor sheets are embedded and installed on one side of the surface of the display panel, and a plurality of indicator lights are embedded and installed on the other side of the surface of the display panel.

[0008] As a preferred embodiment of the present invention, a control sensor is fixedly installed on the surface of the display panel, and an induction sensor is fixedly installed on the side of the display panel near the control sensor.

[0009] As a preferred embodiment of the present invention, the adjustment mechanism includes a rotating component, one end of which is fixedly connected to the back of the display panel, and the other end of which is fixedly connected to a miniature electric push rod. One end of the miniature electric push rod is fixedly connected to a support rod, and one end of the support rod is fixedly connected to the surface of the A-frame rod.

[0010] As a preferred technical solution of the present invention, the shielding mechanism includes a connecting piece A, the bottom of the connecting piece A is fixedly connected to the top of the display board, the side end of the connecting piece A is threadedly connected to a connecting piece B through a threaded rod, the upper surface of the connecting piece B is fixedly connected to a shielding plate, and the outer surface of the threaded rod is threadedly connected to a nut.

[0011] As a preferred technical solution of the present invention, the display mechanism includes a display panel, a main screen is embedded in the middle of the display panel, a secondary screen is embedded in the bottom of the surface of the display panel, a soundboard is embedded in the side of the surface of the display panel, and a camera is mounted on the surface of the display panel.

[0012] As a preferred technical solution of the present invention, a support block is fixedly connected to one side of the bottom of the display board and the display panel, and the support block is arc-shaped and fits against the upper surface of the A base plate and the B base plate.

[0013] As a preferred technical solution of the present invention, the display panel is symmetrically arranged in two groups, and the control sensor is electrically connected to the lighting lamp in the display mechanism, and the sensing sensor is electrically connected to the indicator light.

[0014] As a preferred technical solution of the present invention, both the bottom of the A base plate and the B base plate are fixedly equipped with casters, and the casters are internally connected to brake pads for rotation.

[0015] The beneficial effects of this invention are as follows: 1. The present invention provides a display device for vocational English teaching. By adding an ambient-adaptive dimming light to the display mechanism, the light can automatically adjust its brightness to match the ambient light, regardless of whether the classroom is in a bright daytime with ample natural light, a dimly lit rainy day, or a dimly lit indoor environment for evening self-study. This ensures that the English words, phrases, sentence patterns, and other content on the display board are always clear, glare-free, and reflection-free, providing optimal visual clarity. Students do not need to squint or get too close to see the content due to lighting conditions, significantly reducing visual fatigue and improving concentration. The dimming lighting adjusts its power according to the ambient light requirements, avoiding long-term full-load operation of the lamps, effectively slowing down the aging and wear of components such as LED beads and driver power supplies, extending the lifespan of the light, and reducing the frequency of lamp replacement. 2. The present invention provides a display device for vocational school English teaching. Through an adjustable mechanism, it addresses the common issues of fixed-angle display boards in vocational school classrooms (often tiered or row-seat layouts) causing glare, blind spots, and distorted text when viewed from below by students in the back or side rows. Adjusting the tilt angle allows the display board to be level, tilted forward, or tilted backward, ensuring all students in the front, back, and sides can view the content clearly and without distortion. This prevents errors in word recognition, phonetic transcription, and sentence structure due to viewing angle. The adjustable mechanism frees the display board from fixed-angle limitations, enabling its use in various vocational school teaching spaces such as classrooms, training rooms, campus English corners, and multimedia classrooms. It is suitable not only for regular classroom teaching but also for campus activities such as vocational school English competitions, vocabulary dictation contests, and situational dialogue presentations, thus increasing the device's utilization rate. 3. The present invention provides a display device for vocational school English teaching. Through a shielding mechanism, if the dimming light from the top of the display board shines directly on it, it can easily create bright spots on the surface, reflective text, or glare directly into the eyes. Since the content displayed in vocational school English teaching mainly consists of small-font words, phonetic symbols, and letters, reflections can directly cause the content to become blurry. The adjustable shielding plate can precisely block excessive light from the top by adjusting the angle of the shielding, converting direct light into soft, diffused light, so that the overall light on the display board is evenly distributed without any dark or bright corners. The strokes and spellings of words, phonetic symbols, and sentence patterns are clearly distinguishable, avoiding the problem of students misreading letters or phonetic symbols due to reflections.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Reference Figure 1 - Figure 9 This invention provides two technical solutions: Example 1: A display device for English teaching in vocational high schools includes a base plate A 1, a base plate B 2 hinged to the side of the base plate A 1, a magnetic strip A 3 mounted on the side of the base plate A 1, a magnetic strip B 4 mounted on the side of the base plate B 2, a support rod A 5 fixedly mounted on the upper surface of the base plate A 1, a groove formed at the side end of the support rod A 5, a connecting block 6 rotatably connected inside the groove, a display plate 7 fixedly connected to one end of the connecting block 6, a track groove formed on the surface of the display plate 7, a display mechanism installed inside the track groove, an adjustment mechanism fixedly connected to the back of the display plate 7, a shielding mechanism fixedly mounted on the top of the display plate 7, and a support rod B 8 mounted on the upper surface of the base plate B 2, a display mechanism fixedly connected to the side end of the support rod B 8. The display mechanism includes a magnetic rail 9, which is embedded in the track groove. Magnetic blocks 10 are magnetically attached to the surface of the magnetic rail 9, and a card plate 11 is fixedly connected to one end of the magnetic blocks 10. An illumination lamp 12 is embedded in the inner wall of the card plate 11. With the addition of an ambient-adaptive dimming illumination lamp 12, the illumination lamp 12 can automatically adjust its brightness to match the ambient light, ensuring that the English words, phrases, and sentence patterns on the display card remain clear, glare-free, and reflection-free, providing optimal visual clarity. Students do not need to squint or get too close to see the content due to lighting conditions, significantly reducing visual fatigue and improving concentration. The dimming illumination adjusts its power according to the ambient light requirements, preventing the lamps from operating at full load for extended periods. This effectively slows down the aging and wear of components such as LEDs and power supplies, extending the lifespan of the illumination lamp 12 and reducing the frequency of lamp replacement.

[0021] Example 2: Multiple sets of sensor sheets 13 are embedded on one side of the surface of the display board 7, and multiple sets of indicator lights 14 are embedded on the other side of the surface of the display board 7. A control sensor 15 is fixedly installed on the surface of the display board 7, and a sensor 16 is fixedly installed on the side of the surface of the display board 7 near the control sensor 15. The sensor sheet 13 adopts a high-sensitivity touch-sensitive patch structure and is made of wear-resistant and scratch-resistant conductive sensing material. After being embedded, it is flush with the surface of the display board 7, without any protrusions that would hinder writing and display. Each set of sensor sheets 13 is an independent sensing unit, and the sensing area is precisely calibrated to meet the interactive operation needs of vocational English teaching, such as word recognition, sentence pattern quizzes, and phonetic matching. It can be directly triggered by a light touch of the finger without the need for additional operating tools, which fits the fast-paced interactive characteristics of the classroom.

[0022] The adjustment mechanism includes a rotating component 17, one end of which is fixedly connected to the back of the display board 7, and the other end of which is fixedly connected to a miniature electric push rod 18. One end of the miniature electric push rod 18 is fixedly connected to a support rod 19, and the other end of the support rod 19 is fixedly connected to the surface of the A-frame rod 5. Vocational school classrooms are mostly tiered or row-seat layouts. A fixed-angle display board 7 is prone to glare, blind spots, and text distortion for students in the back and side seats when looking up. Adjusting the tilt angle allows the display board 7 to be adjusted to different angles such as horizontal, forward tilt, or backward tilt according to the classroom layout. This design ensures that all students in the front, back, and sides of the classroom can have a direct viewing angle, guaranteeing that the English words, phonetics, sentence patterns, and example sentences on display board 7 are clear and undistorted. This avoids misreading words, misreading phonetics, and confusing sentence patterns due to viewing angle issues. The adjustment mechanism allows display board 7 to break free from fixed angle limitations and can be used in various vocational school teaching venues such as classrooms, training rooms, campus English corners, and multimedia classrooms. It is not only suitable for regular classroom teaching but also adaptable to campus activities such as vocational school English competitions, word dictation contests, and situational dialogue presentations, thereby improving the utilization rate of the device.

[0023] The shielding mechanism includes a connecting piece A 20, the bottom of which is fixedly connected to the top of the display board 7. The side end of the connecting piece A 20 is threadedly connected to a connecting piece B 22 via a threaded rod 21. A shielding plate 23 is fixedly connected to the upper surface of the connecting piece B 22. A nut 24 is threadedly connected to the outer surface of the threaded rod 21. If the dimming lighting on the top of the display board 7 shines directly on it, it is easy to form bright spots on the top of the board, reflective text, or glare that shines directly into people's eyes. The content of the vocational school English display is mostly small-font words, phonetic symbols, and letters. Reflection will directly cause the content to be blurry. The adjustable shielding plate 23 can accurately shield the excessive light from the top by adjusting the shielding angle, converting the direct light into soft diffused light, so that the overall light of the display board 7 is evenly distributed, without bright and dark dead corners. The strokes and spellings of words, phonetic symbols, and sentence patterns are clearly distinguishable, avoiding the problem of students misreading letters or phonetic symbols due to reflection.

[0024] The display mechanism includes a display panel 25, a main screen 26 embedded in the center of the display panel 25, a secondary screen 27 embedded at the bottom of the surface of the display panel 25, a soundboard 28 embedded at the side of the surface of the display panel 25, and a camera 29 mounted on the surface of the display panel 25. The main screen 26 is the core visual output component of the display mechanism, occupying the main panel area of ​​the display panel 25. It uses a high-definition anti-glare LCD screen, supports touch operation and automatic brightness adjustment, and is suitable for the display needs of large-scale, high-definition teaching content in vocational English classrooms. It can clearly display core teaching content such as English words, phonetics, sentence patterns, text paragraphs, grammar points, teaching courseware, and English animations.

[0025] A support block 30 is fixedly connected to one side of the bottom of both display panel 7 and display panel 25. The support block 30 is arc-shaped and fits against the upper surface of base plate A 1 and base plate B 2. The support block 30 can provide support when the angle of display panel 7 is adjusted. The support plate is arc-shaped and can always be in contact with base plate A 1.

[0026] The display panels 7 are symmetrically arranged in two groups, and the control sensor 15 is electrically connected to the lighting lamp 12 in the display mechanism, and the sensing sensor 16 is electrically connected to the indicator light 14. The track grooves on the display panels 7 are divided into categories. The correct card plate 11 is placed in the appropriate area using the magnetic block 10. The magnetic rail 9 attracts the magnetic block 10 to fix the card plate 11 in the correct area. The sensing sensor 16 and the sensing plate 13 trigger the sensing. If the card plate 11 is not placed in the correct position, the indicator light 14 displays a red light. If the card plate 11 is placed in the correct position, the indicator light 14 displays a green light.

[0027] Both base plate A 1 and base plate B 2 are fixedly installed with casters 31, and the casters 31 are internally connected to brake pads. When the display device needs to be moved, simply push the casters 31 to move it, which improves convenience. When the device needs to be folded, separate magnetic strips A 3 and B 4, and use hinges to fold base plate A 1 and base plate B 2 at an angle to achieve the folding and shrinking effect.

[0028] Working principle: When using the display device, the main screen 26 and the secondary screen 27 are activated, allowing images to be displayed on them. Sound is played from the audio board 28. The camera 29 allows real-time monitoring of students' answering status. When students need to answer questions, the main screen 26 plays teaching content. The track slots on the display board 7 are divided into categories. The correct card 11 is placed in the appropriate area using the magnetic block 10. The magnetic rail 9 attracts the magnetic block 10, securing the card 11 in the correct area. The sensor 16 and the sensor plate 13 trigger the sensing. If the card 11 is not placed correctly, the indicator light 14 shows a red light; if the card 11 is placed correctly, the indicator light 14 shows a green light. Subsequently, during the display on the display board 7, the brightness of the internal lighting light 12 of the card 11 is adjusted according to the environment using the control sensor 15 to better suit the viewer. When the tilt of the display board 7 needs to be adjusted, the miniature electric push rod 1 is activated. 8. The miniature electric push rod 18 drives the rotating part 17 to extend and retract. The rotating part 17 squeezes the display board 7, and the display board 7 rotates within the A frame rod 5 through the connecting block 6 to achieve the effect of angle adjustment. Subsequently, to present the best effect, the angle of the shielding plate 23 is adjusted by raising and lowering it. After adjusting to the appropriate angle, the A connecting piece 20 and the B connecting piece 22 are fixed by the threaded rod 21, and then the nut 24 is used to strengthen the fixation. If the dimming lighting on the top of the display board 7 shines directly, it is easy to form bright spots on the top of the board surface, reflective text, or glare that shines directly into people's eyes. The content of vocational school English displays is mostly small-font words, phonetic symbols, and letters. Reflection will directly cause the content to be blurry. The adjustable shielding plate 23 can accurately block the excessive light from the top by adjusting the covering angle, converting the direct light into soft diffused light, so that the overall light of the display board 7 is evenly distributed, without bright and dark dead corners. The strokes and spellings of words, phonetic symbols, and sentence patterns are clearly distinguishable, avoiding the problem of students misreading letters or phonetic symbols due to reflection.
