Description

Technical Field

[0001] The invention relates to an enlightenment mathematics teaching aid, in particular to an enlightenment mathematics teaching aid for early childhood education, and belongs to the technical field of enlightenment teaching aids. Background Art

[0002] Math kits are tools and toys designed to help infants and preschoolers understand and learn basic math concepts. These kits are usually: intuitive: using concrete objects such as counting blocks and shape puzzles to help children understand math concepts through touch and manipulation; interactive: encouraging children to learn through games and exploration, such as puzzles, sorting games, building blocks, etc.; educational: the design takes into account key math learning skills, such as counting, sorting, sorting, comparing, adding and subtracting; appropriate: taking into account the age and development level of children, the kits are usually brightly colored and sized for children's small hands to operate.

[0003] The Chinese patent, entitled "An Enlightenment Mathematics Teaching Aid for Early Childhood Education" (patent number ZL201910770659.8), discloses an enlightenment mathematics teaching aid technology. By rotating the rotating ring, the Arabic numerals on the rotating ring are displayed in sequence from the display window, so that the children can put the displayed numbers into the fixed rod with the rubber magnetic rings of the number corresponding to the numbers for counting, which can make the children understand counting more vividly, thereby improving the effect of education; when the rotating ring does not need to be rotated, the rotating ring can be stuck by the compression spring hitting the plug ball, thereby preventing the rotating ring from rotating without human power. However, although the teaching aid overcomes the defects of the prior art that it is difficult for children to understand counting more vividly during the enlightenment mathematics education for children, resulting in poor educational effects, etc.; however, the form of expression of the numbers is still relatively single, and it is impossible to effectively combine the numbers with daily objects with images similar to the numbers and display them, and the numbers that can be displayed are very limited by the size of the rotating ring;

[0004] Directly using mobile phones or televisions to play math enlightenment videos to guide children in educational learning can ensure the display effect, but it is easy for children to develop bad habits. For this reason, it is proposed to use enlightenment math teaching aids for early childhood education. Summary of the invention

[0067] The inclined portion 504 drives the toothed locking member 501 to rotate around the connecting shaft 502 under pressure, and drives the torsion spring 503 to twist.

[0068] In one embodiment, the marking drive mechanism 6 includes four reduction motors 601, four gears 602 and a gear ring 603;

[0075] In one embodiment, a projection screen 83 is fixedly connected to one side of the inner wall of the projection plate 103 .

[0076] The projection screen 83 is provided to improve the projection display effect.

[0077] When the present invention is working: first, the enlightenment identification component 3 is selected according to the pattern on the first identification sheet 302 or the enlightenment teaching needs. After the selection is completed, the identification shell 301 is moved and inserted into the interior of the circular housing 201. When the bottom of the identification shell 301 contacts the surface of the toothed locking piece 501, the toothed locking piece 501 is driven to rotate with the connecting shaft 502 as the center under the action of pressure by utilizing the provided inclined portion 504, and the torsion spring 503 is driven to twist. At the same time, the bottom of the circular base 371 is limited by the support 202, so that the second spring 372 is compressed under the action of pressure. When the limiting groove 305 moves to the toothed locking piece 501, the twisted torsion spring 503 drives the toothed locking piece 501 to reset, and the reset toothed locking piece 501 slides into the limiting groove 305, so as to limit the identification shell 301 as a whole inside the circular housing 201, and complete the assembly operation of the enlightenment identification component 3.

[0081] When it is necessary to further provide mathematical enlightenment teaching to the children, two different enlightenment identification components 3 can be installed in the two laser projection mechanisms 2 respectively, and the required second identification piece 82 can be installed in the central seat 81 to provide arithmetic enlightenment teaching to the children.

[0082] When the enlightenment identification component 3 needs to be taken out from the interior of the laser projection mechanism 2, the extension part 402 and the pressure block 404 are driven to move by pressing the pressure ring 401, and the moving extension part 402 drives the first spring 403 to be compressed, and the moving pressure block 404 squeezes the toothed locking member 501, so that it slides out of the limit groove 305 under the action of pressure, so as to release the limit on the identification shell 301, and then the compressed second spring 372 pushes the identification shell 301 and the circular base 371 to reset, so that the entire enlightenment identification component 3 pops out from the interior of the laser projection mechanism 2, so as to replace the enlightenment identification component 3, and then the compressed first spring 403 pushes the extension part 402 to drive the pressure ring 401 to reset as a whole.

[0083] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
