Description

Technical Field

[0001] This invention belongs to the field of intelligent education, specifically an artificial intelligence education system based on educational big data. Background Technology

[0002] With the development of artificial intelligence technology, AI-based educational methods are being gradually promoted in the education field to better develop teaching plans.

[0003] A Chinese patent with publication number CN113870074A discloses an AI-based interactive education system, including a user verification module, a teaching terminal module, a student terminal module, an interaction module, an analysis module, and a storage module. This invention uses the analysis module to understand students' learning abilities and can selectively choose the corresponding number of teaching interactions to ensure students' learning efficiency. Through multiple teaching interactions, students can concentrate on learning.

[0004] The aforementioned AI-based interactive education system still has some problems. In the education system, there are many factors that affect students' learning outcomes. For young students, many of their abilities are not yet fully developed, such as their concentration, observation, and hands-on skills, which all need to be developed. These personality traits also affect students' learning outcomes. In addition, students have different physical conditions and can tolerate different learning intensities. To achieve good educational results, it is necessary to teach according to students' individual characteristics. The aforementioned AI-based interactive education system has not effectively solved this problem.

[0005] Therefore, this invention provides an artificial intelligence education system based on educational big data. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: the present invention provides an artificial intelligence education system based on educational big data, including a student terminal and a server. The student terminal is equipped with a user verification module, a learning module, a manual module, an entertainment module, a feedback module, and an analysis module.

[0008] The user verification module is used to verify the student's identity, and the student logs into the server through the user verification module.

[0009] The learning module includes a teaching unit and a testing unit. The teaching unit is used to output teaching content to students and contains a teaching plan. The testing unit is used to test students' learning outcomes and send the test results to the analysis module.

[0010] The manual module is used to train students' attention and hands-on skills. Specifically, the manual module includes a camera unit. After completing the manual task, students take pictures through the camera unit and send the pictures to the teaching unit. The teaching unit evaluates the manual task through software analysis or manual analysis by the teacher, thereby judging the students' attention and hands-on skills.

[0011] The entertainment module is used to help students relax; specifically, the entertainment module may include game props and toys.

[0012] The feedback module is used to test students' attention and hands-on skills, and sends the test results to the analysis module;

[0013] The server includes a database that stores the average levels of student groups of different ages, and the database updates the stored data based on big data.

[0014] The analysis module is used to analyze students' test results, obtain the student's individual level, compare and analyze it with the average level of peers in the database, and then revise the teaching plan based on the analysis results.

[0015] During the learning process, learning and entertainment modules are set up to allow students to get appropriate rest and achieve a balance between work and rest. Craft modules are included to improve students' attention and hands-on skills, thereby enhancing their learning abilities. By testing students' learning outcomes, attention span, and hands-on skills, their overall level can be measured and compared with that of their peers. This allows for a better assessment of each student's individual characteristics, facilitating the development of targeted teaching plans and ultimately improving educational outcomes.

[0016] Preferably, the student terminal includes a main body and a time module. The main body is equipped with a display screen for displaying teaching content, and the time module is used to control the working time of the learning module, the craft module, and the entertainment module. During operation, the time module sets the student's learning time, craft time, and entertainment time, allowing students to engage in corresponding activities within the specified time. This not only cultivates students' sense of time but also addresses the problem of students spending excessive time on entertainment due to playfulness.

[0017] Preferably, the main body has a cavity, within which the manual module and the entertainment module are placed. A cover plate is slidably installed at the top of the cavity, and its movement is controlled by a time module. During operation, students engage in manual activities and games within the cavity. Initially, the cover plate closes the cavity. When the manual or entertainment module is in operation, the cover plate moves, opening the cavity. Simultaneously, the time module starts, timing the student's manual activity or entertainment time. After the timer expires, the cover plate closes the cavity. By sealing the cavity with the cover plate, students must complete their activities within a specified time, thus developing their time management skills.

[0018] Preferably, a detection plate is movably inserted into the right side of the cover plate, and a support spring is installed on the detection plate. An adjustable plate that can slide up and down is movably installed on the front side of the cover plate. A driving gear and a driven gear are rotatably installed inside the main body. The driving gear and the driven gear are located below and above the cover plate, respectively. The bottom and top ends of the adjustable plate are provided with toothed sections. The adjustable plate is meshed with the driving gear. The adjustable plate and the driven gear are staggered vertically. The driving gear and the driven gear are driven by a chain belt. A control component for controlling the adjustable plate is provided on the detection plate. In operation, initially, the adjusting plate meshes with the driving gear, while the adjusting plate does not contact the driven gear. The main body contains a drive motor that drives the driving gear. When the cover moves and seals the cavity, the driving gear rotates clockwise, causing the adjusting plate and cover to move to the right. If a student is still operating inside the cavity at this time, the detection plate may touch the student's hand or arm, causing the detection plate to be squeezed and moved to the left. This, in turn, causes the adjusting plate to move upwards via the control components. After moving upwards, the adjusting plate is disengaged from the driving gear and meshes with the driven gear. At this point, the driven gear causes the adjusting plate and cover to move to the left, mitigating the potential for squeezing injuries to students if the cover continues to move to the right, thus improving safety.

[0019] Preferably, the control component includes a slide plate slidably installed inside the cover plate. The slide plate is located between the adjustment plate and the detection plate. The left end of the detection plate is inserted into the interior of the slide plate. A limit block is provided at the left end of the detection plate. A limit groove corresponding to the limit block is provided at the right end of the slide plate. A gap is left between the inner left wall of the limit groove and the limit block. Two push plates for pushing the adjustment plate are provided at the left end of the slide plate. The push plates are inclined and are located above and below the slide plate, respectively. In operation, initially, the detection plate extends to the right under the push of the support spring. During the closing of the cover, while the student is still operating inside the cavity, due to the gap between the detection plate and the sliding plate, the detection plate is first squeezed and moved to the left by the student's body, while the sliding plate does not move to the left. The cover continues to move to the right. This gap provides a buffer time for the student to leave the cavity. If the student has not completely left the cavity, the detection plate continues to be squeezed and moved to the left, causing the sliding plate to move to the left as well. After the sliding plate moves to the left, it pushes the adjusting plate upward via the upper push plate, causing the adjusting plate to engage with the driven gear. The driven gear then drives the adjusting plate and the cover to move to the left to prevent further squeezing of the student, allowing the student to leave the cavity more smoothly. After the cover moves to the left and separates from the student, the detection plate moves to the right and resets, and the sliding plate moves via the limit block. The board moves to the right, and the sliding plate moves to the right, pushing the adjusting plate downwards via the push plate below. This causes the adjusting plate to engage with the drive gear, which in turn drives the adjusting plate and the cover plate to move to the right. This cycle continues until the student has completely left the cavity, at which point the cover plate moves to the far right and seals the cavity. Before the student leaves the cavity, the cover plate continues to reciprocate, preventing the student from lingering inside and reminding them to end the activity quickly, thus helping to cultivate their time management skills. During operation, the drive gear rotates in only one direction, eliminating the need for additional electrical sensors and switching the drive motor's operating state. This improves upon traditional door-closing anti-pinch systems, which require infrared sensors and switching the motor's forward and reverse rotation, reducing energy consumption and operating costs. The device is simple in structure and easy to use.

[0020] Preferably, the detection plate is equipped with an acceleration component, and the deceleration component includes a telescopic rod. The two ends of the telescopic rod are hinged to the detection plate and the cover plate, respectively. The telescopic rod is inclined, and a compression spring is provided on its outer side. During operation, the telescopic rod maintains a stable inclined position under the push of the compression spring. During the left-right movement of the detection plate, the state change of the telescopic rod is "extension-compression-extension". When the telescopic rod changes from extension to compression, the compression spring is also compressed and stores energy. When the telescopic rod changes from compression to extension, the compression spring extends and releases energy, thereby providing driving force to the detection plate. This allows the detection plate to quickly drive the sliding plate and the adjustment plate to move, increasing the speed of the adjustment plate when switching between the driving and driven gears. The change in the direction of movement of the cover plate is more rapid, and the cover plate can move to the left more quickly after contacting the student's body, further improving the protection effect for the student.

[0021] Preferably, an elastic sheet is installed inside the cover plate, and a one-way lever corresponding to the elastic sheet is installed on the detection plate. The one-way lever has a one-way rotating structure. During operation, when the detection plate moves to the left and then begins to move to the right, the elastic sheet slows down the rightward movement of the detection plate, thereby reducing the rightward movement speed and prolonging the holding time after the adjustment plate moves up. This allows the cover plate to move a longer distance to the left after touching the student's body, providing more space and time for the student to leave the cavity, resulting in better performance.

[0022] Preferably, a sliding positioning block is installed inside the main body to fix the cover plate. A positioning groove corresponding to the positioning block is provided at the left end of the bottom of the cover plate. During operation, after the cover plate moves to the right and completely seals the cavity, the positioning groove aligns vertically with the positioning block. The positioning block is then moved upwards and inserted into the positioning groove, thus fixing the cover plate from the inside. Because the positioning block is located inside the main body, students cannot open the cover plate from the outside, improving the problem of students opening the cover plate for entertainment due to playfulness, making it safer and more reliable to use.

[0023] Preferably, the positioning block is located to the left of the drive gear. A crossbar is movably inserted inside the positioning block, and a spring is installed on the crossbar. A vertical plate for pushing the crossbar is provided at the left end of the bottom of the cover plate. Alternating levers corresponding to the crossbar are evenly distributed on the drive gear. The adjusting plate, levers, and chain are staggered. In operation, initially, the positioning block extends to the left under the push of the spring. At this time, the positioning block and levers are staggered. When the cover plate is closed, the drive gear rotates, and the levers on the drive gear do not contact the crossbar. When the cover plate moves to the far right, the vertical plate moves to the right and presses the crossbar to extend to the right. At this time, the rotating lever drives the crossbar and positioning block to move upward, causing the positioning block to insert into the positioning groove and fix the cover plate. This achieves the function of automatically fixing the cover plate after it is closed. The structure is simple and easy to use.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. The artificial intelligence education system based on educational big data described in this invention allows students to get appropriate rest during the learning process by setting up learning and entertainment modules, achieving a balance between work and rest; it improves students' attention and hands-on skills by setting up a hands-on module, thereby enhancing their learning ability; by testing students' learning outcomes, attention, and hands-on skills, it measures students' overall level and compares it with the level of their peers, which can better determine the individual characteristics of each student, helping to develop targeted teaching plans and thus improve educational effectiveness.

[0026] 2. The artificial intelligence education system based on educational big data described in this invention uses a cover plate to seal the cavity, preventing students from engaging in unauthorized entertainment. By incorporating a detection plate, cover plate, adjustment plate, driving gear, and driven gear, the cover plate continuously reciprocates before the student leaves the cavity, preventing the student from remaining inside and reminding them to quickly end the activity. This helps cultivate students' time management skills. The system is simple in structure and easy to use. Attached Figure Description

Detailed Implementation

[0037] 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.

[0038] The present invention discloses an artificial intelligence education system based on educational big data, comprising a student terminal and a server. The student terminal is equipped with a user verification module, a learning module, a manual module, an entertainment module, a feedback module, and an analysis module.

[0039] The user verification module is used to verify the student's identity, and the student logs into the server through the user verification module.

[0040] The learning module includes a teaching unit and a testing unit. The teaching unit is used to output teaching content to students and contains a teaching plan. The testing unit is used to test students' learning outcomes and send the test results to the analysis module.

[0041] The manual module is used to train students' attention and hands-on skills. Specifically, the manual module includes a camera unit. After completing the manual task, students take pictures through the camera unit and send the pictures to the teaching unit. The teaching unit evaluates the manual task through software analysis or manual analysis by the teacher, thereby judging the students' attention and hands-on skills.

[0042] The entertainment module is used to help students relax; specifically, the entertainment module may include game props and toys.

[0043] The feedback module is used to test students' attention and hands-on skills, and sends the test results to the analysis module;

[0044] The server includes a database that stores the average levels of student groups of different ages, and the database updates the stored data based on big data.

[0045] The analysis module is used to analyze students' test results, obtain the student's individual level, compare and analyze it with the average level of peers in the database, and then revise the teaching plan based on the analysis results.

[0046] During the learning process, learning and entertainment modules are set up to allow students to get appropriate rest and achieve a balance between work and rest. Craft modules are included to improve students' attention and hands-on skills, thereby enhancing their learning abilities. By testing students' learning outcomes, attention span, and hands-on skills, their overall level can be measured and compared with that of their peers. This allows for a better assessment of each student's individual characteristics, facilitating the development of targeted teaching plans and ultimately improving educational outcomes.

[0047] Example 1

[0048] like Figure 2As shown, the student terminal includes a main body 1 and a time module. The main body 1 is equipped with a display screen 101, which displays teaching content. The time module controls the working time of the learning module, the craft module, and the entertainment module. During operation, the time module sets the student's learning time, craft time, and entertainment time, allowing students to engage in corresponding activities within the specified time. This not only cultivates students' sense of time but also addresses the problem of students spending excessive time on entertainment due to playfulness.

[0049] like Figures 2 to 3 As shown, the main body 1 has a cavity 2, where the manual module and the entertainment module are placed. A cover plate 3 is slidably installed on the top of the cavity 2, and its movement is controlled by a time module. During operation, students perform manual operations and play games within the cavity 2. Initially, the cover plate 3 closes the cavity 2. When the manual or entertainment module is in operation, the cover plate 3 moves, opening the cavity 2. Simultaneously, the time module starts, timing the student's manual operation or entertainment time. After the timer expires, the cover plate 3 closes the cavity 2. By sealing the cavity 2 with the cover plate 3, students need to finish their corresponding activities within a specified time, thus developing their time management skills.

[0050] like Figures 2 to 4 As shown, a detection plate 4 is movably inserted into the right side of the cover plate 3, and a support spring is installed on the detection plate 4. An adjustable plate 5 that can slide up and down is movably installed on the front side of the cover plate 3. A drive gear 6 and a driven gear 7 are rotatably installed inside the main body 1. The drive gear 6 and the driven gear 7 are located below and above the cover plate 3, respectively. The bottom and top ends of the adjustable plate 5 are provided with toothed sections. The adjustable plate 5 is meshed with the drive gear 6, and the adjustable plate 5 and the driven gear 7 are staggered vertically. The drive gear 6 and the driven gear 7 are transmitted through a chain belt 8. A control component for controlling the adjustable plate 5 is provided on the detection plate 4. In operation, initially, the adjusting plate 5 is engaged with the driving gear 6, and the adjusting plate 5 is not in contact with the driven gear 7. The main body 1 is equipped with a drive motor to drive the driving gear 6. When the cover plate 3 moves and seals the cavity 2, the driving gear 6 is activated to rotate clockwise. The driving gear 6 drives the adjusting plate 5 and the cover plate 3 to move to the right. If the student is still operating inside the cavity 2 at this time, the detection plate 4 will touch the student's hand or arm or other body parts. The detection plate 4 is squeezed to the left and drives the adjusting plate 5 to move upward through the control component. After the adjusting plate 5 moves upward, it is displaced from the driving gear 6 and engages with the driven gear 7. At this time, the driven gear 7 drives the adjusting plate 5 and the cover plate 3 to move to the left, which improves the situation where the cover plate 3 may cause squeezing injury to the student if it continues to move to the right, thus improving the safety of use.

[0051] like Figures 3 to 7As shown, the control component includes a slide plate 9 slidably installed inside the cover plate 3. The slide plate 9 is located between the adjustment plate 5 and the detection plate 4. The left end of the detection plate 4 is inserted into the interior of the slide plate 9. A limit block is provided at the left end of the detection plate 4. A limit groove corresponding to the limit block is provided at the right end of the slide plate 9. A gap is left between the inner left wall of the limit groove and the limit block. Two push plates 10 for pushing the adjustment plate 5 are provided at the left end of the slide plate 9. The push plates 10 are inclined and are located above and below the slide plate 9, respectively. In operation, initially, the detection plate 4 extends to the right under the push of the support spring. During the closing of the cover plate 3, while the student is still operating inside the cavity 2, due to the gap between the detection plate 4 and the slide plate 9, the detection plate 4 is first squeezed by the student's body and moved to the left, while the slide plate 9 does not move to the left. The cover plate 3 continues to move to the right. This gap provides a buffer time for the student to leave the cavity 2. If the student has not completely left the cavity 2, the detection plate 4 continues to be squeezed to the left, causing the slide plate 9 to move to the left. After the slide plate 9 moves to the left, it pushes the adjusting plate 5 upward through the upper push plate 10, causing the adjusting plate 5 to engage with the driven gear 7. The driven gear 7 drives the adjusting plate 5 and the cover plate 3 to move to the left to prevent further squeezing of the student, allowing the student to leave the cavity 2 more smoothly. After the cover plate 3 moves to the left and separates from the student, the detection plate 4 moves to the right and resets, and is stopped by the limit block. The sliding plate 9 moves to the right, and the rightward movement of the sliding plate 9 pushes the adjusting plate 5 downward through the push plate 10 below, causing the adjusting plate 5 to engage with the drive gear 6. The drive gear 6 then drives the adjusting plate 5 and the cover plate 3 to move to the right. This cycle continues until the student has completely left the cavity 2, at which point the cover plate 3 moves to the far right and seals the cavity 2. Before the student leaves the cavity 2, the cover plate 3 continues to reciprocate, preventing the student from remaining in the cavity 2 and reminding the student to end the activity quickly, which helps cultivate the student's time management skills. During operation, the drive gear 6 always rotates in one direction, eliminating the need for additional power induction devices and switching the drive motor's operating state. This improves upon traditional door-closing anti-pinch systems, which require infrared sensors and switching the motor's forward and reverse rotation, reducing energy consumption and operating costs. The device is simple in structure and easy to use.

[0052] like Figures 3 to 7As shown, the detection plate 4 is equipped with an acceleration component 11, and the deceleration component includes a telescopic rod. The two ends of the telescopic rod are hinged to the detection plate 4 and the cover plate 3, respectively. The telescopic rod is inclined, and a compression spring is provided on its outer side. During operation, the telescopic rod maintains a stable inclined position under the push of the compression spring. During the left-right movement of the detection plate 4, the state change of the telescopic rod is "extension-compression-extension". When the telescopic rod changes from extension to compression, the compression spring is also compressed and stores energy. When the telescopic rod changes from compression to extension, the compression spring extends and releases energy, thereby providing driving force to the detection plate 4. This allows the detection plate 4 to quickly drive the sliding plate 9 and the adjusting plate 5 to move, increasing the speed at which the adjusting plate 5 switches with the driving gear 6 and the driven gear 7. The change in the direction of movement of the cover plate 3 is more rapid, and the cover plate 3 can move to the left more quickly after contacting the student's body, further improving the protection effect for the student.

[0053] like Figure 5 As shown, an elastic sheet 12 is installed inside the cover plate 3, and a one-way lever 13 corresponding to the elastic sheet 12 is installed on the detection plate 4. The one-way lever 13 has a one-way rotating structure. During operation, when the detection plate 4 moves to the left and then begins to move to the right, the elastic sheet 12 will slow down the rightward movement speed of the detection plate 4, thereby reducing the rightward movement speed of the detection plate 4 and extending the holding time after the adjustment plate 5 moves upward. This allows the cover plate 3 to move a longer distance to the left after touching the student's body part, providing more space and time for the student to leave the cavity 2, resulting in better performance.

[0054] like Figures 3 to 6 As shown, a movable positioning block 14 is installed inside the main body 1. The positioning block 14 is used to fix the cover plate 3. A positioning groove 15 corresponding to the positioning block 14 is opened at the left end of the bottom of the cover plate 3. During operation, after the cover plate 3 moves to the right and completely seals the cavity 2, the positioning groove 15 is aligned vertically with the positioning block 14. The positioning block 14 is then moved upward and inserted into the positioning groove 15, which can fix the cover plate 3 from the inside. Since the positioning block 14 is located inside the main body 1, students cannot open the cover plate 3 from the outside, which improves the problem of students opening the cover plate 3 for entertainment due to playfulness, making it safer and more reliable to use.

[0055] like Figures 3 to 7As shown, the positioning block 14 is located to the left of the drive gear 6. A crossbar 16 is movably inserted inside the positioning block 14, and a spring is installed on the crossbar 16. A vertical plate 17 for pushing the crossbar 16 is provided at the left end of the bottom of the cover plate 3. The drive gear 6 has levers 18 evenly distributed, corresponding to the crossbar 16. The adjusting plate 5, levers 18, and chain belt 8 are staggered. In operation, initially, the positioning block 14 extends to the left under the push of the spring. At this time, the positioning block 14 and levers 18 are staggered. When the cover plate 3 is closed, the drive gear 6 is started to rotate, and the levers 18 on the drive gear 6 will not contact the crossbar 16. When the cover plate 3 moves to the rightmost position, the vertical plate 17 moves to the right and squeezes the crossbar 16 to extend to the right. At this time, the rotating levers 18 drive the crossbar 16 and positioning block 14 to move upward, so that the positioning block 14 inserts into the positioning groove 15 and fixes the cover plate 3. This realizes the function of automatically fixing after the cover plate 3 is closed. The structure is simple and easy to use.

[0056] Example 2

[0057] like Figure 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the lever 18 is rotatably mounted on the drive gear 6, a return spring is installed on the lever 18, and a limiting seat 19 corresponding to the lever 18 is provided on the drive gear 6. The limiting seat 19 is arc-shaped. During operation, the lever 18 can swing within a certain range. With this arrangement, when the vertical plate 17 presses the horizontal bar 16 to the right, even if the horizontal bar 16 abuts against the lever 18, the lever 18 will swing and deviate from the horizontal bar 16. This allows the lever 18 or the next lever 18 to continue pushing the horizontal bar 16 upward after the drive gear 6 continues to rotate. This improves the problem that the lever 18 in the fixed structure may jam with the horizontal bar 16, making it more reliable in use.

[0058] Working principle:

[0059] Students engage in manual activities and games within cavity 2. Initially, cover 3 seals cavity 2. When the manual or entertainment module is in operation, cover 3 moves, opening cavity 2. Simultaneously, the time module starts, timing the time spent on manual activities or entertainment. After the timer expires, cover 3 closes cavity 2. By sealing cavity 2 with cover 3, students need to finish their corresponding activities within a specified time, thus developing their time management skills.

[0060] In the initial state, the adjusting plate 5 is engaged with the driving gear 6, and the adjusting plate 5 is not in contact with the driven gear 7. The main body 1 is equipped with a drive motor to drive the driving gear 6. When the cover plate 3 moves and seals the cavity 2, the driving gear 6 is started to rotate clockwise. The driving gear 6 drives the adjusting plate 5 and the cover plate 3 to move to the right. If the student is still operating inside the cavity 2 at this time, the detection plate 4 will touch the student's hands or arms and other body parts. The detection plate 4 is squeezed to the left and drives the adjusting plate 5 to move upward through the control component. After the adjusting plate 5 moves upward, it is displaced from the driving gear 6 and engages with the driven gear 7. At this time, the driven gear 7 drives the adjusting plate 5 and the cover plate 3 to move to the left, which improves the situation where the cover plate 3 may cause squeezing injury to the student if it continues to move to the right, and improves the safety of use.

[0061] Initially, the detection plate 4 extends to the right under the push of the support spring. During the closing of the cover plate 3, while the student is still operating inside the cavity 2, due to the gap between the detection plate 4 and the slide plate 9, the detection plate 4 is first squeezed by the student's body and moved to the left, while the slide plate 9 does not move to the left. The cover plate 3 continues to move to the right. This gap provides a buffer time for the student to leave the cavity 2. If the student has not completely left the cavity 2, the detection plate 4 continues to be squeezed to the left, causing the slide plate 9 to move to the left. After the slide plate 9 moves to the left, it pushes the adjusting plate 5 upward through the push plate 10 above, causing the adjusting plate 5 to engage with the driven gear 7. The driven gear 7 drives the adjusting plate 5 and the cover plate 3 to move to the left to avoid further squeezing the student, allowing the student to leave the cavity 2 more smoothly. After the cover plate 3 moves to the left and separates from the student, the detection plate 4 moves to the right and resets, and is driven by the limit block. The sliding plate 9 moves to the right, and the rightward movement of the sliding plate 9 pushes the adjusting plate 5 downward through the push plate 10 below, causing the adjusting plate 5 to switch to meshing with the drive gear 6. The drive gear 6 drives the adjusting plate 5 and the cover plate 3 to move to the right. This cycle continues until the student has completely left the cavity 2, at which point the cover plate 3 moves to the far right and seals the cavity 2. Before the student leaves the cavity 2, the cover plate 3 continues to reciprocate, preventing the student from staying in the cavity 2 and reminding the student to end the activity quickly, which helps to cultivate the student's time management skills. During the operation of this device, the drive gear 6 always rotates in one direction, eliminating the need for additional power sensing devices and switching the working state of the drive motor. This improves upon the traditional door closing anti-pinch system, which requires infrared sensors and the trouble of switching the motor forward and reverse, reducing the energy consumption generated when switching the motor, lowering the operating cost, and making the structure simple and easy to use.

[0062] The telescopic rod can maintain a stable tilt under the push of the compression spring. During the left and right movement of the detection plate 4, the state change process of the telescopic rod is "extension-compression-extension". When the telescopic rod changes from extension to compression, the compression spring is also compressed and stores energy. When the telescopic rod changes from compression to extension, the compression spring extends and releases energy, thereby providing driving force to the detection plate 4. This allows the detection plate 4 to quickly drive the slide plate 9 and the adjustment plate 5 to move, which increases the speed when the adjustment plate 5 switches with the driving gear 6 and the driven gear 7. The direction of movement of the cover plate 3 changes more rapidly. After the cover plate 3 comes into contact with the student's body, it can move to the left more quickly, further improving the protection effect for the student.

[0063] When the detection plate 4 moves to the left and then begins to move to the right, the elastic sheet 12 will slow down the rightward movement speed of the detection plate 4, thereby slowing down the rightward movement speed of the detection plate 4 and extending the holding time after the adjustment plate 5 moves upward. This allows the cover plate 3 to move a longer distance to the left after touching the student's body part, providing more space and time for the student to leave the cavity 2, resulting in better performance.

[0064] After the cover plate 3 moves to the right and completely seals the cavity 2, the positioning groove 15 and the positioning block 14 are aligned vertically. The positioning block 14 is then moved upward and inserted into the positioning groove 15, which can fix the cover plate 3 from the inside. Since the positioning block 14 is located inside the main body 1, students cannot open the cover plate 3 from the outside, which improves the problem of students opening the cover plate 3 for entertainment due to playfulness, making it safer and more reliable to use.

[0065] In the initial state, the positioning block 14 extends to the left under the push of the spring. At this time, the positioning block 14 and the lever 18 are offset to the left and right. When the cover plate 3 is closed, the drive gear 6 is started to rotate. The lever 18 on the drive gear 6 will not contact the crossbar 16. When the cover plate 3 moves to the rightmost position, the vertical plate 17 moves to the right and squeezes the crossbar 16 to extend to the right. At this time, the rotating lever 18 drives the crossbar 16 and the positioning block 14 to move upward, so that the positioning block 14 is inserted into the positioning groove 15 and the cover plate 3 is fixed. This realizes the function of automatically fixing the cover plate 3 after it is closed. The structure is simple and easy to use.

[0066] The lever 18 can swing within a certain range. With this setting, when the vertical plate 17 presses the horizontal bar 16 to the right, even if the horizontal bar 16 blocks the lever 18, the lever 18 will swing and be offset from the horizontal bar 16. This allows the lever 18 or the next lever 18 to continue pushing the horizontal bar 16 upward after the drive gear 6 continues to rotate. This improves the problem that the lever 18 of the fixed structure may jam with the horizontal bar 16, making it more reliable to use.
