Description

Technical Field

[0001] The present invention relates to the technical field of mathematics teaching, and particularly relates to an intelligent mathematics and applied mathematics difficult problem analysis display stand. Background Art

[0002] A difficult problem analysis display stand for mathematics is a teaching aid specifically designed for mathematics teaching. It combines the advantages of traditional teaching blackboard writing and modern display technologies, aiming to improve the efficiency and intuitiveness of difficult problem analysis in mathematics. In a mathematics classroom, a teacher can write or project key information such as complex mathematics problems, problem-solving steps, graphs, or formulas on a display panel for the whole class to watch together. This not only makes the information transmission more intuitive and clear, but also helps students better understand the problem-solving process of difficult problems with the aid of vision.

[0003] Generally, when using a difficult problem analysis display stand for mathematics, a teacher needs to continuously write on the blackboard and then erase the writing. The erasure of the writing consumes a large amount of teaching time and will interrupt the students' train of thought, thus affecting the teaching efficiency.

[0004] To sum up, how to solve the problem that a teacher continuously erases the writing on the blackboard during the teaching process, which consumes a large amount of teaching time and interrupts the students' train of thought, thus affecting the teaching efficiency has become a technical problem that needs to be solved urgently by those skilled in the art. Therefore, it is necessary to propose an intelligent mathematics and applied mathematics difficult problem analysis display stand. Summary of the Invention

[0005] To solve the above problems, the present invention provides an intelligent mathematics and applied mathematics difficult problem analysis display stand. By controlling the electromagnet to turn off through a controller, a blackboard eraser always abuts against the blackboard under the elastic force of a spring. By controlling an extension member to extend through the controller, the rotation of the blackboard is controlled. As the blackboard rotates, the blackboard eraser can erase the writing on the blackboard, thereby reducing the time for a teacher to continuously erase the writing and improving the teaching efficiency of the teacher.

[0006] To achieve the above object, the technical solution of the present invention is as follows: An intelligent mathematics and applied mathematics difficult problem analysis display stand includes a display stand body. A support assembly for supporting the display stand body is provided at the bottom of the display stand body. A display screen and a controller are fixedly connected to one side of the display stand body. The controller is in signal connection with the display screen. A writing assembly for writing on the blackboard and a cleaning assembly for cleaning writing dust are provided on the display stand body.

[0007] The writing assembly includes a blackboard. A sliding block is rotatably connected to one side of the blackboard. The sliding block is slidably matched with the display stand body.

[0008] A driving assembly for driving the rotation of the blackboard and an erasing assembly for erasing the writing on the blackboard are provided on the side of the display stand body away from the display screen.

[0009] The erasing component includes an electromagnet, and the controller is used to control the opening and closing of the electromagnet. The electromagnet is fixedly connected to the side of the display rack body away from the display screen. Several springs are fixedly connected to the side of the electromagnet close to the blackboard, and a blackboard eraser is fixedly connected to the end of the spring away from the electromagnet.

[0010] The technical principle of the above solution is as follows:

[0011] Write on the blackboard, and display math problems and their solutions on the display screen. Drive the blackboard to rotate through the driving component, so as to adjust the display angle of the blackboard, enabling the problem writing on the blackboard to be displayed in all directions. Close the electromagnet through the controller to release the blackboard eraser, and the spring pushes the blackboard eraser to contact the blackboard, so as to erase the writing on the blackboard as the blackboard rotates.

[0012] Clean the writing dust erased by the blackboard eraser through the cleaning component to reduce the impact of the writing dust on the teacher. Support the display rack body through the support component to keep the display rack body stable.

[0013] The above solution has the following beneficial effects:

[0014] 1. In the present invention, the controller controls the electromagnet to close, and the blackboard eraser can abut against the blackboard under the elastic force of the spring, thereby erasing the writing on the blackboard by the teacher, reducing the time for the teacher to erase the writing on the blackboard by themselves, improving the teaching efficiency of the teacher. The driving component drives the blackboard to rotate and adjusts the angle of the blackboard, which is beneficial for students to observe the problem writing on the blackboard in all directions, thereby improving the teaching quality of the teacher in the teaching process.

[0015] 2. In the present invention, the teaching task is completed through the cooperation of the blackboard and the display screen. The teacher can project the problem solution on the display screen and write on the blackboard. The blackboard and the display screen are used in cooperation to improve the understanding efficiency of students for difficult problems.

[0016] 3. In the present invention, the cleaning component cleans the writing dust erased by the blackboard eraser, keeps the blackboard surface clean, and can reduce the inhalation of writing dust by the teacher.

[0017] Furthermore, the driving component includes a telescopic member and a rotating rod. The controller is used to control the operation of the telescopic member. Both ends of the rotating rod are rotatably connected to the display rack body, and one end of the rotating rod penetrates through the display rack body and is fixedly connected with a gear.

[0018] The telescopic member is fixedly connected to the display rack body, and the output shaft of the telescopic member is fixedly connected with a rack, and the rack meshes with the gear.

[0019] An L-shaped pull rod is fixedly connected to the rotating rod, and the end of the pull rod away from the rotating rod is hinged to the blackboard.

[0020] Beneficial effects: The telescopic member is controlled by the controller to expand and contract, realizing the automatic adjustment of the position of the blackboard, which is beneficial for students to clearly see each step and detail during viewing, thereby improving students' understanding of math problems.

[0021] Furthermore, the cleaning component includes a piston cylinder fixedly connected to one side of the display rack body. An air inlet and an air outlet are provided on the piston cylinder. One-way valves are fixedly connected to both the air inlet and the air outlet. A piston head is slidably fitted in the piston cylinder.

[0022] One side of the sliding block close to the piston cylinder is fixedly connected with a connecting rod, and one end of the connecting rod away from the sliding block penetrates through the display rack body and is fixedly connected with the piston head.

[0023] The air inlet is communicated with a collection component.

[0024] Beneficial effects: The sliding of the sliding rod drives the connecting rod to move, thereby driving the piston head to slide in the piston cylinder, and then generating suction, enabling the gas to enter the air inlet through the collection component. The suction can drive the writing dust into the collection component, reducing dust diffusion.

[0025] Furthermore, the collection component includes a collection hopper detachably connected to the blackboard, and one side of the collection hopper away from the blackboard is communicated with the air inlet.

[0026] Beneficial effects: The connection design between the collection hopper and the air inlet ensures that the gas generated when the piston head makes a piston movement with the side wall of the piston cylinder can directly suck the writing dust into the collection hopper. This design reduces the scattering of dust and debris inside or around the display rack body, thereby improving the cleaning efficiency. The detachable connection between the collection hopper and the blackboard enables the teacher to easily remove the collection hopper from the display rack body for cleaning or replacement.

[0027] Furthermore, a filter screen is fixedly connected to the connection part between the collection hopper and the air inlet.

[0028] Beneficial effects: The design of the filter screen can block the dust and fine particles generated during the inhalation of the writing dust by the collection hopper, keeping them in the collection hopper and preventing them from being discharged into the environment again through the air outlet.

[0029] Furthermore, the support component includes several support legs, and all the support legs are fixedly connected to the display rack body.

[0030] Beneficial effects: The display rack body is supported by the support legs, which is beneficial for reducing the tipping or deformation of the display rack body during the teaching process by the teacher and improving the stability of the display rack body.

[0031] Furthermore, a lighting lamp is fixedly connected to the blackboard, and the controller is used to control the opening and closing of the lighting lamp.

[0032] Beneficial effects: The lighting lamp can directly illuminate the blackboard area, ensuring that the content written by the teacher is clearly visible, making it easier for students to understand and absorb knowledge.

[0033] Furthermore, universal wheels are fixedly connected to the bottoms of the support legs.

[0034] Beneficial effects: Through the universal wheels, the teacher can easily move the display rack body to any classroom, enhancing the flexibility of the classroom teaching location.

[0035] Furthermore, a dust cover for protecting the gears, racks and telescopic members is fixedly connected to the display rack body.

[0036] Beneficial effects: Through the dust cover, the situation of writing dust entering the gears, racks and telescopic members can be significantly reduced, which is beneficial to extending the service life of the gears, racks and telescopic members.

[0037] Furthermore, a transparent window is fixedly connected to the surface of the collection hopper.

[0038] Beneficial effects: The teacher can observe the collection situation of the writing dust in the collection hopper through the transparent window, so as to replace it in time and improve the collection efficiency of the collection hopper.

[0039] The additional aspects and advantages of the present invention will be partially given in the following description, partially become obvious from the following description, or be understood through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Specific Embodiment

[0046] The following is a further detailed description through specific embodiments:

[0047] Embodiment 1:

[0048] As shown in the attached Figures 1 - 5 figures: An intelligent mathematics and application mathematics problem analysis display rack includes a display rack body 1. A support assembly for supporting the display rack body 1 is provided at the bottom of the display rack body 1. A display screen 2 and a controller are fixedly connected by screws on one side of the display rack body 1. The controller is in signal connection with the display screen 2. A writing assembly for writing on the blackboard and a cleaning assembly for cleaning the writing dust are provided on the display rack body 1.

[0049] As Figure 1 and Figure 4 shown in the figures, the writing assembly includes a blackboard 5. A sliding block 13 is rotatably connected to one side of the blackboard 5. The sliding block 13 is slidably matched with the display rack body 1.

[0050] A driving assembly for driving the blackboard 5 to rotate and an erasing assembly for erasing the handwriting on the blackboard are provided on the side of the display rack body 1 away from the display screen 2.

[0051] As Figure 2 shown in the figures, the erasing assembly includes an electromagnet 9. The controller is used to control the opening and closing of the electromagnet 9. The electromagnet 9 is fixedly connected by screws on the side of the display rack body 1 away from the display screen 2. A plurality of springs 18 are fixedly connected by screws to the side of the electromagnet 9 close to the blackboard 5. One end of the spring 18 away from the electromagnet 9 is fixedly connected by screws to a blackboard eraser 19.

[0052] Combined with Figure 3 the figures shown, the driving assembly includes a telescopic member and a rotating rod 3. In this embodiment, the telescopic member is selected as an electric telescopic rod 12. The controller is used to control the operation of the electric telescopic rod 12. Both ends of the rotating rod 3 are rotatably connected to the display rack body 1. One end of the rotating rod 3 penetrates through the display rack body 1 and is fixedly connected by bolts to a gear 10.

[0053] The electric telescopic rod 12 is fixedly connected by screws to the display rack body 1. The output shaft of the electric telescopic rod 12 is fixedly connected by screws to a rack 11. The rack 11 is meshed with the gear 10.

[0054] As Figure 1As shown, a bolt is fixedly connected to the rotating rod 3 with an L-shaped pull rod 4, and one end of the pull rod 4 away from the rotating rod 3 is hinged to the blackboard 5.

[0055] Combined with Figure 5 As shown, the cleaning assembly includes a piston cylinder 7, and the piston cylinder 7 is fixedly connected to one side of the display rack body 1 by bolts. An air inlet 17 and an air outlet 16 are formed in the piston cylinder 7. One-way valves are fixedly connected and communicated in both the air inlet 17 and the air outlet 16 by screws. A piston head 15 is slidably fitted in the piston cylinder 7.

[0056] One side of the sliding block 13 close to the piston cylinder 7 is fixedly connected with a connecting rod 14 by screws. One end of the connecting rod 14 away from the sliding block 13 penetrates through the display rack body 1 and is fixedly connected with the piston head 15 by screws.

[0057] Combined with Figure 1 As shown, the air inlet 17 is communicated with a collection assembly. The collection assembly includes a collection hopper 6. The collection hopper 6 is detachably connected to the blackboard 5, and one side of the collection hopper 6 away from the blackboard 5 is communicated with the air inlet 17.

[0058] A filter screen (not shown in the figure) is fixedly connected and communicated at the connection between the collection hopper 6 and the air inlet 17 by screws.

[0059] The support assembly includes a plurality of support legs 8, and all the support legs 8 are fixedly connected to the display rack body 1 by bolts. Universal wheels (not shown in the figure) are fixedly connected to the bottoms of the support legs 8 by bolts.

[0060] The specific implementation process is as follows: First, the teacher can move the display rack body 1 to the position where teaching is needed through the universal wheels. After determining the position, the teacher can input the difficult math problems to be explained into the controller through the mobile terminal and display them on the display screen 2. In this embodiment, the mobile terminal is selected as a mobile phone.

[0061] After the difficult math problems are displayed on the display screen 2, the teacher can use chalk to write on the blackboard 5, writing the problem-solving process and key points and difficulties.

[0062] After the teacher finishes writing, taking Figure 1 as an example, the teacher can control the electric telescopic rod 12 to extend through the controller. Combined with Figure 3 as shown, when the electric telescopic rod 12 extends, the electric telescopic rod 12 will push the rack 11 to move. The rotation of the gear 10 will drive the rotating rod 3 to rotate, and then drive the pull rod 4 to rotate. The rotation of the pull rod 4 will drive the blackboard 5 to rotate. At this time, with the rotation of the blackboard 5, the surrounding students can watch the problem-solving process and key points and difficulties written by the teacher in all directions, thereby promoting the students' understanding of the difficult math problems.

[0063] Combined with Figure 2As shown, when the teacher writes on the blackboard 5, the electromagnet 9 is always in the on state. The electromagnet 9 attracts the eraser 19 by magnetic force, and the eraser 19 always abuts against the electromagnet 9.

[0064] When the teacher finishes writing and needs to erase the writing on the blackboard 5, the teacher can turn off the electromagnet 9 through the controller. At this time, the magnetic force between the electromagnet 9 and the eraser 19 disappears, and the eraser 19 abuts against the blackboard 5 under the elastic force of the spring 18.

[0065] At this time, if the teacher controls the telescopic movement of the electric telescopic rod 12 through the controller to drive the blackboard 5 to rotate, the eraser 19 will slide on the blackboard 5, thereby erasing the writing on the blackboard 5.

[0066] When the eraser 19 finishes erasing the writing on the blackboard 5, the teacher can turn on the electromagnet 9 again through the controller, so that the eraser 19 abuts against the electromagnet 9 again, thereby stopping the erasing of the writing.

[0067] By erasing the writing on the blackboard 5 with the eraser 19, the time for the teacher to manually erase the writing is reduced, the concentration of the students is improved, and thus the teaching effect of the teacher is improved.

[0068] Combined with Figure 4 and Figure 5 As shown, a large amount of writing dust is generated as the eraser 19 erases the writing on the blackboard 5. Since the sliding block 13 is slidably engaged with the display rack body 1 and the sliding block 13 is rotatably connected to the blackboard 5, when the pull rod 4 drives the blackboard 5 to rotate, the sliding block 13 will also slide. At this time, the sliding block 13 drives the piston head 15 to slide in the piston cylinder 7 through the connecting rod 14.

[0069] Taking Figure 5 as an example, when the piston head 15 slides to the right, the gas enters the piston cylinder 7 through the collection hopper 6 and the air inlet 17. At this time, the writing dust on the blackboard 5 enters the collection hopper 6, and the writing dust is filtered and stored in the collection hopper 6 due to the filtering effect of the filter screen.

[0070] By collecting the writing dust through the collection hopper 6, the writing dust in the classroom can be reduced, providing a fresher and healthier learning environment for teachers and students. And by collecting the writing dust, the influence of the writing dust on teachers can be reduced.

[0071] Embodiment 2:

[0072] The difference from the above embodiment is that a lighting lamp (not shown in the figure) is fixedly connected to the blackboard 5 by screws, and the controller is used to control the on and off of the lighting lamp.

[0073] The specific implementation process is as follows: When the light is dim, the teacher can turn on the lighting lamp through the controller, and use the lighting lamp to illuminate the blackboard 5. Through the lighting lamp, the lighting quality of the blackboard 5 area can be significantly improved, ensuring that students can clearly see the content on the blackboard 5 when the teacher is writing and explaining, thereby improving the teaching effect and learning efficiency.

[0074] Embodiment 3:

[0075] The difference from the above embodiment is that a dust-proof cover (not shown in the figure) for protecting the gear 10, the rack 11, and the electric telescopic rod 12 is fixedly connected to the display rack body 1 by screws.

[0076] The specific implementation process is as follows: The dust-proof cover can effectively prevent the writing dust in the air from entering the gear 10, the rack 11, and the electric telescopic rod 12, extend the service life of the gear 10, the rack 11, and the electric telescopic rod 12, and improve the stability during the rotation of the blackboard 5.

[0077] Embodiment 4:

[0078] The difference from the above embodiment is that a transparent window (not shown in the figure) is fixedly connected to the surface of the collection hopper 6 by screws.

[0079] The specific implementation process is as follows: Through the transparent window, the teacher can directly observe the collection situation of the writing dust in the collection hopper 6. By cleaning the writing dust in the collection hopper 6 in advance, it is beneficial to improve the teaching efficiency of the teacher during the teaching process.

[0080] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
