Description

Technical Field

[0001] This invention relates to the field of teaching device technology, specifically to an intelligent mathematics teaching aid device for mathematics teaching. Background Technology

[0002] Mathematics teaching is a comprehensive teaching activity in which teachers systematically explain mathematical knowledge, train logical reasoning, and cultivate problem-solving abilities based on the teaching syllabus and the laws of students' cognitive development. Its teaching content covers algebraic operations, function analysis, teaching of geometric solid figures, and cultivation of spatial imagination, aiming to help students build a complete mathematical knowledge system and improve their abstract thinking, logical thinking and spatial thinking abilities. In the process of mathematics teaching, the dynamic changes of complex figures can be presented and dynamically demonstrated by electronic whiteboards, which transforms abstract mathematical knowledge into visual and dynamic teaching content, making it easier for all students to observe and understand at the same time, and significantly improving the efficiency of classroom information transmission and the overall teaching effect. In existing technologies, electronic whiteboards are often installed in combination with traditional blackboards. When wiping the blackboard, a large amount of chalk dust is generated and floats in the air. Electronic whiteboards are prone to static electricity during operation. Static electricity will continuously attract dust from the air. After long-term use, a large amount of dust will adhere to the surface of the whiteboard, causing problems such as blurry images and unresponsive touch controls, which will significantly reduce the user experience and teaching effectiveness. Therefore, an intelligent mathematics teaching aid device for mathematics teaching is proposed to address the above problems. Summary of the Invention

[0011] As a further optimization of the present invention, the screw is helically connected to an internal threaded cylinder, and a horizontal plate is fixedly connected to the top and bottom of the internal threaded cylinder. The horizontal plate has multiple through holes on its inner side, and the horizontal plate is sleeved around the screw through the through holes.

[0012] As a further optimization of the present invention, the following features are provided: a movable groove is provided on the inner side of the horizontal plate, a positioning pin is fixedly connected to the inner side of the movable groove, an extension block is rotatably connected to the outer side of the positioning pin, the extension block protrudes from the front end of the movable groove by a distance of 0.8cm to 0.95cm, a cross plate is fixedly connected to the rear end of the extension block, a spring plate is fixedly connected to the front end of the cross plate, and the spring plate protrudes from the front end of the movable groove by a distance of 0.39cm to 0.5cm.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0019] Please see Figures 1-10 The present invention provides a technical solution: An intelligent mathematics teaching aid device for mathematics teaching includes a blackboard 1, a track 2, and a teaching aid component 3. A protective component 4 is installed at the rear end of the teaching aid component 3. A drive component 5 is installed inside the protective component 4. Multiple cleaning components 6 are installed outside the drive component 5. The protective component 4 includes a metal frame 41. A rubber pad 44 is fixedly connected to the rear end of the metal frame 41. A rubber sleeve 45 is fixedly connected to the front end of the metal frame 41. The drive component 5 includes a transmission column 51. The outer side of the transmission column 51 is fixedly connected to the driving disc of an electric clutch 53. A screw 54 is fixedly connected to the top end of the transmission column 51. A cover 55 is fixedly connected to the top end of the driven disc of the electric clutch 53. A roller 56 is rotatably connected to one end of the cover 55.

[0020] As a further implementation of this solution, the teaching auxiliary component 3 includes an electronic whiteboard 31. Track blocks 32 are fixedly connected to the top and bottom of the electronic whiteboard 31. A track 2 is slidably connected to the rear end of the track blocks 32. One end of the track 2 is fixedly connected to the blackboard 1. A first spring telescopic rod 47 is fixedly connected to the rear end of the electronic whiteboard 31. The piston rod of the first spring telescopic rod 47 is fixedly connected to the side of the metal frame 41. Through the above arrangement, the sliding cooperation between the track blocks 32 and the track 2 enables the electronic whiteboard 31 to move smoothly left and right. Combined with the telescopic action of the first spring telescopic rod 47, it can drive the metal frame 41 to move back and forth, achieving the contact and separation of the rubber pad 44 and the blackboard 1. This reduces the friction when the electronic whiteboard 31 moves, and ensures the stability of the electronic whiteboard 31's position after movement through the elasticity of the first spring telescopic rod 47, providing a foundation for subsequent chalk cleaning and normal equipment use, and improving operational convenience. As a further implementation of this solution, the rear end of the electronic whiteboard 31 is fixedly connected to the rubber sleeve 45. The rear end of the electronic whiteboard 31 is fixedly connected to a first upright plate 33 and a second upright plate 35. The first upright plate 33 has multiple recessed grooves 34 near the rear end, and the second upright plate 35 has toothed grooves 36 near the rear end. Through the above arrangement, the rubber sleeve 45 can form a closed space with the metal frame 41 and the rubber pad 44, which restricts the chalk dust from spreading outward and prevents the dust from adsorbing onto the surface of the electronic whiteboard 31 and affecting the use of the equipment. The recessed grooves 34 provide rotation space for the extension block 63, and the toothed grooves 36 can collide with the spring plate 65 to generate vibration, which provides conditions for the vibration and dust removal of the cleaning components, further improving the cleaning effect, while protecting the electronic whiteboard 31 from dust contamination. As a further implementation of this solution, through holes are provided at both the top and bottom of the metal frame 41. A blower 42 is fixedly connected to the top of the metal frame 41, and a dust collection bag 43 is fixedly connected to the bottom of the metal frame 41. Through the above arrangement, the through holes provide a channel for component installation and airflow. The blower 42 can deliver air into the enclosed space to blow away dust on the surface of the blackboard 1 and the cleaning components. The dust collection bag 43 can filter the dust-laden airflow, effectively intercepting dust and preventing dust from spreading. At the same time, the airflow can cool down the electronic whiteboard 31 and the rear aluminum alloy plate, taking into account cleaning, dust prevention and equipment protection, improving the service life of the equipment and the user experience. As a further implementation of this solution, a guide post 46 is fixedly connected to the inner side of the metal frame 41, and a sleeve 48 is slidably connected to the outer side of the guide post 46. Both ends of the sleeve 48 are fixedly connected to the cleaning components 6. Multiple cleaning components 6 are separated by multiple sleeves 48. Through the above arrangement, the sliding cooperation between the guide post 46 and the sleeve 48 can ensure the stability of the cleaning components 6 when moving up and down. Multiple cleaning components 6 can be synchronously raised and lowered by being separated by the sleeves 48, which expands the chalk writing cleaning range, improves cleaning efficiency, and avoids mutual interference among multiple cleaning components 6, ensuring a smooth cleaning process and ensuring that the blackboard surface is clean and uniform. As a further implementation of this solution, the transmission column 51 is rotatably connected to the inside of the metal frame 41 via a bearing. The transmission column 51 and the metal frame 41 are sealed by a rubber ring. The bottom end of the transmission column 51 is fixedly connected to the end of the main shaft of the servo motor 52. The housing of the servo motor 52 is fixedly connected to the bottom end of the metal frame 41. Through the above settings, the bearing connection can reduce the friction when the transmission column 51 rotates, ensuring smooth rotation. The rubber ring seal can prevent dust from entering the connection between the transmission column 51 and the metal frame 41, avoiding component wear and rotation jamming. The servo motor 52 provides stable power to the transmission column 51, ensuring that the transmission column 51 accurately controls the operation of related components, improving the stability of equipment operation and long-term effectiveness. As a further implementation of this solution, the cover 55 is fitted on the outside of the screw 54, and a spring 57 is fixedly connected to the outside of the screw 54. One end of the spring 57 is fixedly connected to the inside of the cover 55, and the roller 56 is in contact with the blackboard 1. Through the above arrangement, the torque of the spring 57 can make the cover 55 maintain a tendency to rotate in the direction of the blackboard 1, ensuring that the roller 56 is always in contact with the blackboard 1, which facilitates precise control of the rotation angle of the screw 54 and the cover 55. The contact between the roller 56 and the blackboard 1 can generate rolling friction when the electronic whiteboard 31 is displaced, reducing displacement resistance and labor intensity. At the same time, after displacement, the position of the electronic whiteboard 31 is fixed by friction, ensuring the smooth operation of subsequent operations. As a further implementation of this solution, an internal threaded cylinder 58 is spirally connected to the outside of the screw 54. A horizontal plate 61 is fixedly connected to the top and bottom of the internal threaded cylinder 58. Multiple through holes are opened on the inner side of the horizontal plate 61. The horizontal plate 61 is sleeved on the outside of the screw 54 through the through holes. With the above arrangement, when the screw 54 rotates, it can drive the internal threaded cylinder 58 to move up and down, thereby driving the horizontal plate 61 to move synchronously, providing power for the up and down displacement of the cleaning component. The through hole design can prevent friction between the horizontal plate 61 and the screw 54, ensuring smooth movement. As a further implementation of this solution, a movable groove 62 is provided on the inner side of the horizontal plate 61. A positioning pin 68 is fixedly connected to the inner side of the movable groove 62, and an extension block 63 is rotatably connected to the outer side of the positioning pin 68. The extension block 63 protrudes from the front end of the movable groove 62 with a gap of 0.8cm to 0.95cm. A cross plate 64 is fixedly connected to the rear end of the extension block 63, and a spring plate 65 is fixedly connected to the front end of the cross plate 64. The spring plate 65 protrudes from the front end of the movable groove 62 with a gap of 0.39cm to 0.5cm. Through the above settings, the positioning pin 68 can ensure that the extension block 63 can rotate flexibly. The reasonable gap setting can make the extension block 63 fit smoothly with the first vertical plate 33 and the spring plate 65 collide smoothly with the tooth groove 36, thereby generating vibration and transmitting it to the cleaning component to achieve rapid dust removal. At the same time, it avoids the gap being too large or too small, which would affect the component matching and ensure the stable realization of the vibration dust removal and alternating cleaning functions. As a further implementation of this solution, the rear end of the span board 64 is fixedly connected to the mounting base 66 via a second spring telescopic rod. Two erasing plates 67 are fixedly connected to the rear end of the mounting base 66. The erasing plates 67 are in contact with the front end of the blackboard 1. Through the above settings, the second spring telescopic rod can adapt to the rotation and displacement of the mounting base 66, ensuring that the two erasing plates 67 can alternately contact the blackboard 1 to achieve continuous cleaning. The contact between the erasing plates 67 and the blackboard 1 can ensure that the chalk writing is thoroughly cleaned. With the help of vibration, surface dust can be quickly removed, reducing the dust accumulation rate, improving cleanliness and cleaning efficiency, and ensuring a clean teaching environment.

[0021] Work process; Example 1: In use, an aluminum alloy plate is fixed to the rear end of the electronic whiteboard 31 to prevent dust from entering the interior of the electronic whiteboard 31. The displacement of the electronic whiteboard 31 is controlled by remote control technology. Before the transmission column 51 is started, the electric clutch 53 is controlled to be in the "engaged" state. When the servo motor 52 starts and drives the electric clutch 53 to rotate, the electric clutch 53 will drive the cover 55 and roller 56 to rotate through the driving and driven discs. The spring spring 57, when the electric clutch 53 is in the "disengaged" state, uses its torque to keep the cover 55 rotating towards the blackboard 1, ensuring that the roller 56 remains in contact with the front end of the blackboard 1. This facilitates precise control of the rotation angle of the screw 54 and the cover 55. As the roller 56 rotates with the cover 55, the friction between the roller 56 and the blackboard 1 causes the roller 56 to rotate. Although the screw 54 will drive multiple cleaning components 6 to move up and down through the internal threaded cylinder 58, the displacement of the cleaning components 6 will not affect the working product. Interference occurs, and under the action of the reaction force, the cover 55 is controlled to push the screw 54 and the transmission column 51 forward, which in turn causes the transmission column 51 to drive the metal frame 41 forward, causing the metal frame 41 to move the rubber pad 44 away from the blackboard 1. At the same time, the first spring telescopic rod 47 retracts, pushing the electronic whiteboard 31 to move left and right. The rail block 32 slides with the rail 2. During this process, since the rubber pad 44 does not contact the blackboard 1, the roller 56 rolls. After moving to the designated position, the servo motor 52 and the electric clutch 53 are controlled to reset the roller 56 and the screw 54. The elastic force of the first spring telescopic rod 47 makes the rubber pad 44 stick tightly to the blackboard 1 again. The above principle can significantly reduce the friction and labor intensity when operating the electronic whiteboard 31 to cover the chalk writing for displacement, and improve the effectiveness of long-term use. At the same time, after moving to the designated position, the friction ensures the stability of the electronic whiteboard 31 position, which is beneficial for the later cleaning of the chalk writing. Example 2: When cleaning chalk writing, following the same principle, while controlling the forward and backward displacement of the metal frame 41, the rubber sleeve 45 is deformed by the compression of the metal frame 41. After the rubber pad 44 is attached to the blackboard 1, the air inside the rubber sleeve 45, metal frame 41, and rubber pad 44 is separated, and the air can only flow from the direction of the blower 42 and dust collector bag 43. The electric clutch 53 is controlled to be in the "disengaged" state. When the drive column 51 is started to control the main shaft to rotate in both forward and reverse directions, the cover 55 will not rotate with the screw 54. The screw 54 drives the inner threaded cylinder 58 connected by the outer thread to move up and down. The inner threaded cylinder 58 drives multiple cleaning components 6, which are connected by the sleeve 48. At this time, all cleaning components 6 move up and down at the same time, and the blackboard is cleaned by the cleaning components 6. The chalk writing on the surface of board 1 is erased. At the same time, the blower 42 is activated to deliver external air into the rubber sleeve 45, metal frame 41 and rubber pad 44, thereby blowing the dust on the surface of board 1 and the cleaning component 6. The dust inside the rubber sleeve 45, metal frame 41 and rubber pad 44 is carried into the dust collection bag 43 by the airflow. The dust collection bag 43 filters the dust in the air. At the same time, when the gas flows inside the rubber sleeve 45, metal frame 41 and rubber pad 44, it will cool the aluminum alloy plate at the rear of the electronic whiteboard 31 and the electronic whiteboard 31. The above principle can limit the outward diffusion of dust when cleaning chalk writing, thereby preventing chalk dust from contacting the screen of the electronic whiteboard 31 during operation. This ensures that the electronic whiteboard 31 does not cause problems such as blurry screen and unresponsive touch, thus improving the user experience and teaching effect. Example 3: During cleaning by cleaning component 6, following the same principle as above, when controlling the up-and-down movement of cleaning component 6, one of the upper or lower wiping plates 67 will contact the blackboard 1. The wiping plate 67 erases the chalk writing on the surface of the blackboard 1, causing a certain deformation of the wiping plate 67. Simultaneously, the front end of the extension block 63 adheres to the rear end of the first vertical plate 33, and the front end of the spring plate 65 continuously collides with the toothed groove 36. Through this collision, the spring plate 65 vibrates. The vibration of the spring plate 65 is transmitted to the wiping plate 67 through the cross plate 64 and the mounting base 66. Under the action of vibration, the dust on the surface of the wiping plate 67 can be quickly detached from the wiping plate 67, extending... After the elongated block 63 enters the recessed groove 34, it moves upward through the transmission column 51 to control the cleaning component 6. During this process, the end of the elongated block 63 twists inside the recessed groove 34. The elongated block 63 drives the cross plate 64, the mounting base 66 and the wiping plate 67 to rotate simultaneously. When the mounting base 66 compresses the second spring telescopic rod, it contracts. At this time, the other wiping plate 67 comes into contact with the blackboard 1, and the previous wiping plate 67 separates from the blackboard 1. The two wiping plates 67 alternately clean the blackboard 1 using the method of cleaning and vibration cleaning, which can improve the cleanliness of the chalk writing on the surface of the blackboard 1, reduce the accumulation rate of dust on the wiping plate 67, and improve the user experience.
