Description

Technical Field

[0001] The invention relates to the technical field of electronic blackboards, in particular to an interactive electronic blackboard and teaching all-in-one machine. Background Art

[0002] With the rapid development of information technology and the deepening of educational reform, the demand for teaching tools in the field of education is becoming increasingly diversified and intelligent. Traditional teaching blackboards can no longer meet the needs of modern teaching, especially in today's world where the amount of information has increased dramatically and teaching methods have become more diverse. Therefore, interactive electronic blackboards and teaching all-in-one machines came into being and became an important symbol of educational modernization. Interactive electronic blackboards not only retain the basic functions of traditional blackboards, such as chalk writing, but also achieve seamless switching between traditional teaching blackboards and intelligent electronic blackboards through nano-touch technology. This technology not only improves the interactivity of teaching, but also enables the teaching content to be saved and flexibly called in real time, greatly saving the time and physical energy of wiping the blackboard.

[0003] In the design of traditional interactive electronic blackboards and all-in-one teaching machines, there are still some problems during use, especially in the environment where chalk writing and electronic display coexist. The electrostatic adsorption of chalk dust and scratches on the surface of the electronic whiteboard are particularly prominent. The electrostatic dust generated when writing with chalk is easy to adhere to the surface of the electronic whiteboard, which not only affects the display effect, but may also cause screen wear due to long-term accumulation and reduce the service life of the equipment. In addition, if the stylus applies too much pressure during the writing process, it may directly damage the screen of the electronic whiteboard, causing permanent deformation, seriously affecting the touch accuracy and projection effect.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1 to 9 , an interactive electronic blackboard and teaching all-in-one machine, comprising:

[0033] A frame 1, one side surface of the frame 1 is provided with two fixed blackboards 2, an electronic whiteboard 4 is provided between the two fixed blackboards 2, one side surface of the frame 1 is also provided with two slidable movable blackboards 3, one side surface of the movable blackboard 3 is provided with a pull handle 6, one side surface of the frame 1 is provided with a wheel groove for facilitating the sliding of the two movable blackboards 3, one side surface of the frame 1 is provided with a mounting assembly, the mounting assembly includes: two fixing bars 18, the two fixing bars 18 are fixed on the indoor wall, the upper surface of the fixing bars 18 is clamped with a clamping bar 40, both sides of the clamping bar 40 are provided with movable movable buckles 41, both sides of the fixing bars 18 are provided with clamping holes matched with the movable buckles 41, one side of the frame 1 is provided with a projector 5, and the projector 5 is hoisted under the indoor ceiling;

[0034] When in use, the device is installed on the indoor wall through the installation component. During the installation process, the two fixing strips 18 are fixed to the wall by expansion screws, and then the card strip 40 is engaged with the card holes on the fixing strip 18 through the movable buckles 41 on both sides thereof, so as to realize the rapid installation and stable positioning of the frame 1. One side surface of the frame 1 is equipped with two fixed blackboards 2 and two slidable movable blackboards 3. The fixed blackboard 2 is a traditional chalk writing area, and the movable blackboard 3 can be flexibly slid on the surface of the frame 1 through the handle 6 and the wheel groove, so that the user can adjust the use of the blackboard space according to teaching needs. An electronic whiteboard 4 is arranged between the fixed blackboards 2. The user can display teaching courseware, video materials, etc. through a computer or other device connected to the electronic whiteboard 4. A projector 5 is also arranged on one side of the frame 1. The projector 5 is suspended under the ceiling of the room, and is used to project the content on the computer or other device onto the electronic whiteboard 4 or the wall to realize a large-screen display.

[0035] The above process is the basic process of using interactive electronic blackboards.

[0036] However, in actual use, when the chalk is written on the blackboard, the tiny particles in the chalk will generate static electricity due to friction. These chalk powders with static electricity are easily attracted to the surface of the electronic whiteboard 4 and attached to it. The attraction of static electricity makes it difficult for these powders to fall off naturally, forming a fine covering layer. In this case, when using the stylus 10 to write on the surface of the electronic whiteboard 4, the pen tip will inevitably come into contact with these attached chalk powders and apply pressure. As the writing progresses, the powder particles slide on the screen under the push of the pen tip, causing tiny scratches or wear. Especially under long-term and high-frequency use, this wear will accumulate and become more obvious. The original design of the electronic whiteboard 4 is to be used with a projector to achieve clear image and text display. However, when the screen surface is covered with chalk powder and scratches are generated, these defects will reflect or scatter the projection light, resulting in blurring, ghosting or uneven brightness of the projected image and text, which seriously reduces the display effect and teaching quality.

[0037] And because the screen of the electronic whiteboard 4 of the interactive motor blackboard is usually made of high-strength glass, hard plastic or other durable materials, but these materials still have a certain pressure tolerance limit. If excessive pressure is applied when using the stylus 10, especially when the pen tip contacts a fixed point on the screen and continues to apply pressure, it may cause the screen to be permanently deformed in that area. This deformation may appear as a depression, convexity or irregular curve on the screen surface, seriously affecting the projection effect and touch accuracy;

[0038] Therefore, based on the above problem, we first designed a cleaning mechanism, which consists of a wiping component and a dust removal component. The wiping component includes: two mounting plates 21, both mounting plates 21 are fixedly mounted on both sides of the inner center of the frame 1, a driving motor 22 is arranged at the center of one side of the mounting plate 21, a fixing plate 23 is arranged on one side of the mounting plate 21, and connecting blocks 29 are fixedly mounted on the upper and lower surfaces of the fixing plate 23, and the connecting block 29 is fixedly connected to the inner side surface of the frame 1, and a slide groove 30 is arranged at the center of the fixing plate 23, and a slidable sliding disk 31 is arranged inside the slide groove 30. A retracting rod 32 is provided on one side surface of the sliding disk 31, and the other end of the retracting rod 32 is connected to the output shaft surface of the driving motor 22. A cleaning roller 28 is provided on one side surface of the sliding disk 31. The upper and lower surfaces of the electronic whiteboard 4 are respectively provided with a limiting bin 26 and a cleaning bin 24 that match the cleaning roller 28. A mounting disk 27 is fixedly installed on the upper surface of the limiting bin 26, and the mounting disk 27 is fixedly connected to the inner upper surface of the frame 1. A water outlet 37 is provided on the inner upper surface of the cleaning bin 24. A water pipe 17 connected to the water outlet 37 is connected to one side surface of the cleaning bin 24.

A visual window 34 is provided on one side surface of the inner water tank 33. A small water pump 35 is provided inside the inner water tank 33. The water outlet end of the small water pump 35 inside the water storage tank 14 is connected to one end of the water delivery pipe 17, and the water pumping end of the small water pump 35 inside the wastewater tank 15 is connected to one end of the water inlet pipe 16. A pull rod 20 is fixedly connected to one side surface of the two inner water tanks 33. A limiting strip 19 is also provided on one side surface of the frame 1 to facilitate the extraction and loading of the inner water tank 33.

[0039] When the electronic whiteboard 4 is in use, the drive motor 22 of the wiping assembly is started by a user signal, and the drive motor 22 drives the sliding plate 31 to slide in the slide groove 30 through the retracting rod 32, and the cleaning roller 28 on the sliding plate 31 moves back and forth between the limiting bin 26 and the cleaning bin 24 of the electronic whiteboard 4, and wipes the surface of the electronic whiteboard 4 to remove the chalk powder attached to the surface of the electronic whiteboard. During the cleaning process, when the cleaning roller 28 moves to the inside of the cleaning bin 24, it presses the pressing button 36 inside the cleaning bin 24 as it moves, and then the storage is driven by pressing the button 36. The small pump 35 in the water tank 14 is started, and clean water is delivered to the water outlet 37 of the cleaning bin 24 through the water pipe 17, and the surface of the cleaning roller 28 is rinsed to remove impurities on the surface, so that the cleaning roller 28 remains moist, and the powder attached to the surface of the electronic whiteboard 4 is easier to remove. The cleaned sewage and powder mixture flows into the transfer box 25 through the drain port 38, and then discharged into the wastewater tank 15 through the water inlet pipe 16. After use, the staff can pull the pull rod 20 to draw out the inner water tank 33 inside the water storage tank 14 and the wastewater tank 15, and fill / clean the interior thereof.

[0040] The dust removal component includes: an air outlet box 7, which is fixedly mounted on the upper surface of the frame 1, a dust box 8 is also fixedly mounted on the bottom surface of the frame 1, a pull-out interception plate 12 is provided on the bottom surface of the dust box 8, a flow fan 42 is provided inside the air outlet box 7 and the dust box 8, air vents 13 for air outlet / intake are provided on both sides of the air outlet box 7 and the dust box 8, a dust inlet 39 is also provided on the upper surface of the dust box 8, a mounting component is fixedly mounted on one side surface of the dust removal component, a start button 11 is provided on one side surface of the frame 1, and there is an electrical connection between the start button 11 and the air outlet box 7 and the flow fan 42 inside the dust box 8;

[0041] When the equipment is in use, the staff activates the dust removal component by pressing the start button 11, and the air flow fan 42 in the air outlet box 7 and the dust collection box 8 starts working. The air outlet box 7 blows the dust on the surface of the equipment downward, and makes the dust collection box 8 inhale the air containing chalk dust through the dust inlet 39. After the dust in the air is intercepted by the internal interception plate 12, it is discharged from the air outlet 13 of the air outlet box 7, forming an air circulation and reducing dust accumulation. In addition, the air flow formed between the air outlet box 7 and the dust collection box 8 can quickly dry the water stains on the surface of the electronic whiteboard 4 after wiping by the wiping component, so that the normal use of the equipment is not affected. When the blowing effect acts on the water stains, it can also increase the humidity around the equipment and reduce the generation of static electricity through higher humidity, so as to reduce the adsorption effect of dust on the surface of the electronic whiteboard 4.

[0042] At the same time, based on the above problems, we have also designed an anti-pressure mechanism, which includes: a pen storage box 9, which is fixedly mounted on one side surface of the frame 1 and located above the dust inlet 39, a stylus 10 is placed inside the pen storage box 9, one end of the stylus 10 is provided with two mounting plates 43, a rotatable touch end 44 is provided between the two mounting plates 43, one end of the touch end 44 is provided with a contact head 45, one end of the contact head 45 is provided with a pressure sensing rod 55, the pressure sensing rod 55 is located inside the touch end 44, the other end of the pressure sensing rod 55 is connected to a small processor 54, the surface of the pressure sensing rod 55 is sleeved with a connecting cross plate 56, the bottom surface of the connecting cross plate 56 is provided with a connecting spring 57, the bottom surface of the connecting spring 57 is provided with a sliding sheet 59, and the inner two side surfaces of the touch end 44 are provided with sliding paths 60 for facilitating the sliding of the sliding sheet 59. An electric lifting rod 58 is provided on the bottom surface of the sliding sheet 59, and there is an electrical connection between the electric lifting rod 58 and the small processor 54. A pen holder 47 is provided at the other end of the touch end 44, and a liftable pushing plate is provided inside the pen holder 47. A push paddle 50 is connected to one side surface of the pushing plate. A shaft body is provided on both sides of the touch end 44. A driving disk 46 is provided on the side surface of the mounting sheet 43 on one side, and the output end of the driving disk 46 is connected to the shaft body on one side of the touch end 44. A control button 53 is provided on one side surface of the touch pen 10, and there is an electrical connection between the control button 53 and the driving disk 46. A first card slot 48 and a second card slot 49 that match the push paddle 50 are provided on the surface of the mounting sheet 43 on the other side. A lifting leak tube 51 that matches the pen holder 47 is also provided at one end of the touch pen 10, and an anti-drop paddle 52 is connected to one side surface of the lifting leak tube 51.

[0043] When the user needs to write on the surface of the electronic whiteboard 4, the user opens the pen storage box 9, takes out the stylus 10 and writes on the surface of the electronic whiteboard 4. When the contact head 45 of the stylus 10 contacts the surface of the electronic whiteboard 4 and applies pressure, the pressure sensing rod 55 transmits the pressure signal to the small processor 54. If the pressure exceeds the preset threshold, the small processor 54 controls the electric lifting rod 58 to work, pushing the sliding sheet 59 to slide in the sliding channel 60, so that 57 is stretched, so that the contact head 45 is easier to shrink after contacting the surface of the electronic whiteboard 4, thereby avoiding too strong pressure on the surface of the electronic whiteboard 4, thereby reducing the pressure on the surface of the electronic whiteboard. The user can adjust the writing mode of the stylus 10 through the control button 53. The control button 53 is electrically connected to the drive disk 46. The rotation of the drive disk 46 can drive the contact end 44 to rotate, and the push paddle 50 on one side of the pen holder 47 is rotated out from the inside of the second card slot 49 and slides into the inside of the first card slot 48 to limit and stop. The end of the pen holder 47 is exchanged with the touch end 44, and the interior of the pen holder 47 is filled with chalk, and writing can be done on the surfaces of the movable blackboard 3 and the fixed blackboard 2 to meet different writing needs. Because the interior of the first card slot 48 is provided with a vertical slot, the user can use up the leaked part of the chalk, and push the push paddle 50 to drive the push plate to push out the chalk inside, so as to continue to use it. After use, the user pushes the anti-drop paddle 52 to lift the chalk out. The leakage reducing tube 51 is pushed out from the inside of the stylus 10 and engages with the bottom surface of the pen container 47, so as to lock the chalk inside the pen container 47 and the lifting leakage tube 51, so as to prevent the chalk from escaping. Moreover, because the lifting leakage tube 51 and the surface of the pen storage box 9 are provided with a plurality of windows, when the stylus 10 is placed inside the pen storage box 9, the dust inside can be cleaned by the dust suction box 8 while sucking dust, and the dust on the surface of the chalk can be sucked out, so as to reduce the dust diffusion when it is used next time.

[0044] The working principle of the present invention is:

[0045] When in use, the frame 1 is quickly installed and firmly positioned by fixing the two fixing strips 18 on the wall, and then the card strip 40 is engaged with the card holes on the fixing strip 18 through the movable buckles 41 on both sides thereof. One side surface of the frame 1 is provided with two fixed blackboards 2 and two slidable movable blackboards 3. An electronic whiteboard 4 is arranged between the fixed blackboards 2. Users can display teaching courseware, video materials, etc. through a computer or other device connected to the electronic whiteboard 4. A projector 5 is also arranged on one side of the frame 1. The projector 5 is suspended under the ceiling of the room and is used to project the content on the computer or other device onto the electronic whiteboard 4 or the wall to realize a large-screen display.

[0046] When the electronic whiteboard 4 is in use, the drive motor 22 of the wiping assembly is started by a user signal, and the drive motor 22 drives the sliding plate 31 to slide in the slide groove 30 through the retracting rod 32, and the cleaning roller 28 on the sliding plate 31 moves back and forth between the limiting chamber 26 and the cleaning chamber 24 of the electronic whiteboard 4, and wipes the surface of the electronic whiteboard 4 to remove the chalk powder attached to the surface of the electronic whiteboard. During the cleaning process, when the cleaning roller 28 moves to the inside of the cleaning chamber 24, the cleaning roller 28 presses against the inside of the cleaning chamber 24 as it moves. Press the button 36, and then, by pressing the button 36, the small water pump 35 in the water storage tank 14 is driven to start, and clean water is delivered to the water outlet 37 of the cleaning chamber 24 through the water pipe 17, and the surface of the cleaning roller 28 is washed. The cleaned sewage and powder mixture flows into the transfer box 25 through the drain port 38, and then discharged into the waste water tank 15 through the water inlet pipe 16. After use, the staff can pull the pull rod 20 to draw out the inner water tank 33 inside the water storage tank 14 and the waste water tank 15, and fill / clean the inside thereof;

[0047] When the device is in use, the dust removal component is activated by the staff starting button 11, and the air flow fan 42 in the air outlet box 7 and the dust collection box 8 starts to work, the air outlet box 7 blows the dust on the surface of the device downward, and the dust collection box 8 inhales the air containing chalk dust through the dust inlet 39, and the dust in the air is intercepted by the internal interception plate 12, and then discharged from the air outlet 13 of the air outlet box 7, forming an air circulation to reduce dust accumulation. In addition, the air flow formed between the air outlet box 7 and the dust collection box 8 can quickly dry the water stains on the surface of the electronic whiteboard 4 after the wiping component is wiped, so that the normal use of the device is not affected;

[0048] When the user needs to write on the surface of the electronic whiteboard 4, the user opens the pen storage box 9, takes out the stylus 10 and writes on the surface of the electronic whiteboard 4. When the contact head 45 of the stylus 10 contacts the surface of the electronic whiteboard 4 and applies pressure, the pressure sensing rod 55 transmits the pressure signal to the small processor 54. If the pressure exceeds the preset threshold, the small processor 54 controls the electric lifting rod 58 to work, pushing the sliding sheet 59 to slide in the sliding channel 60, so that 57 is stretched, so that the contact head 45 is easier to shrink after contacting the surface of the electronic whiteboard 4, thereby avoiding too strong pressure on the surface of the electronic whiteboard 4, thereby reducing the pressure on the surface of the electronic whiteboard. The user can adjust the writing mode of the stylus 10 through the control button 53. The control button 53 is electrically connected to the drive disk 46. The rotation of the drive disk 46 can drive the contact end 44 to rotate, and the push paddle 50 on one side of the pen holder 47 is rotated out from the inside of the second card slot 49 and slides into the inside of the first card slot 48 to limit and stop. The end of the pen holder 47 is exchanged with the touch end 44, and the interior of the pen holder 47 is filled with chalk, and writing can be done on the surfaces of the movable blackboard 3 and the fixed blackboard 2 to meet different writing needs. Because the interior of the first card slot 48 is provided with a vertical slot, the user can use up the leaked part of the chalk, and push the push paddle 50 to drive the push plate to push out the chalk inside, so as to continue to use it. After use, the user pushes the anti-drop paddle 52 to lift the chalk out. The leakage reducing tube 51 is pushed out from the inside of the stylus 10 and engages with the bottom surface of the pen container 47, so as to lock the chalk inside the pen container 47 and the lifting leakage tube 51, so as to prevent the chalk from escaping. Moreover, because the surfaces of the lifting leakage tube 51 and the pen storage box 9 are provided with a plurality of windows, when the stylus 10 is placed inside the pen storage box 9, the dust inside can be cleaned by the dust suction box 8 while sucking dust, and the dust on the surface of the chalk can be sucked out, so as to reduce the dust diffusion when it is used next time.
