Description

Technical Field

[0001] This utility model relates to the field of mathematical teaching tools, and in particular to a preschool children's mathematical thinking enlightenment operation box. Background Technology

[0002] The Preschool Math Thinking Development Activity Box is a math learning playground designed specifically for children aged 3-6. It makes abstract mathematical knowledge tangible and relatable. The box includes brightly colored number cards, geometric blocks for building, animal-shaped magnets for sorting, and a fun task booklet. For example, children can build a number castle with blocks to learn the correspondence between quantities 1-10, understand quantity and length comparison through magnet sorting games, or complete simple addition and subtraction tasks such as sorting fruits according to the task booklet. Through building, arranging, and counting, children can easily develop number sense, understand basic mathematical concepts, and improve their logical reasoning and hand-eye coordination. It turns what was originally a boring math learning experience into an interactive game that children want to participate in every day, helping them fall in love with math and build a solid foundation for thinking skills through play.

[0003] This preschool children's math thinking development activity box is designed with operability and strong interaction as its core features. It contains three main modules: basic cognitive components include colored number cards with numbers on the front and figurative patterns on the back, geometric blocks of different materials with size markings, and reusable magnetic stickers with animal and fruit themes; scenario-based operation tools include a magnetic whiteboard with scales, a detachable number track, and a transparent sorting box; and accompanying guidance resources include a picture and text task book with phased mini-games, parent guidance cards indicating the usage of components, and fun reward stickers. The whole set takes into account both learning and play, helping children understand mathematical concepts.

[0004] In existing technologies, some preschool children's math thinking development activity boxes are prone to sliding or even tipping over when children are taking out or putting in components. This not only causes small parts such as number cards and geometric blocks to scatter all over the floor, increasing the difficulty of storage and the risk of loss, but also poses a safety hazard, as children may slip or trip over the scattered components when reaching for them. At the same time, the sliding boxes interrupt children's focused operation, reducing their interest in the activity and affecting their coherent understanding of mathematical concepts and the development of their thinking, thus weakening the effect of early education. Therefore, a preschool children's math thinking development activity box is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a preschool children's mathematical thinking enlightenment operation box, which aims to improve the problems of some preschool children's mathematical thinking enlightenment operation boxes in the prior art. Due to the lack of anti-slip and fixing design of the drawer, the components are easy to slide and tip over when taking them out, resulting in parts being scattered and difficult to store, posing safety hazards, interrupting children's concentration, reducing interest and affecting the development of mathematical cognition and thinking, thus weakening the enlightenment effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A preschool children's mathematical thinking enlightenment operation box includes an outer shell, a protective shell fixedly connected inside the outer shell, a fixing mechanism fixedly connected inside the protective shell, a square shell installed on the front side of the outer shell, and a protective mechanism installed inside the square shell.

[0008] The fixing mechanism includes an electric push rod, the drive end of which is fixedly connected inside the protective shell. The drive end of the electric push rod is fixedly connected to a push shaft, a push block is fixedly connected to the outside of the push shaft, a rotating shaft is fixedly connected to the outside of the push block, a connecting rod is rotatably connected to the outside of the rotating shaft, a fixed shaft is fixedly connected to the other end of the connecting rod, and a rotating assembly is fixedly connected to the outside of the fixed shaft.

[0009] As a further description of the above technical solution:

[0011] As a further description of the above technical solution:

[0012] The protective mechanism includes a protective wear-resistant layer, a structural support layer is fixedly connected to the bottom of the protective wear-resistant layer, and an interactive functional layer is fixedly connected to the bottom of the structural support layer.

[0013] As a further description of the above technical solution:

[0014] The inside of the square shell is fixedly connected to the top of the fixing block, the front side of the protective shell is fixedly connected to the rear side of the support frame, and the top of the support frame is fixedly connected to the inner wall of the outer shell.

[0015] As a further description of the above technical solution:

[0016] The external part of the push block is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is fixedly connected to one end of the rotating rod.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example: A preschool children's mathematical thinking development activity box, referring to... Figures 1 to 3 The system includes an outer shell 1, which serves as the external frame of the entire operating box, providing overall support and protection. A protective shell 2 is fixedly connected inside the outer shell 1. The protective shell 2 is fixedly connected inside the outer shell 1 and mainly protects the internal fixing mechanism 3, preventing the fixing mechanism 3 from being affected by external collisions or dust, and ensuring that the fixing mechanism 3 can operate stably. The fixing mechanism 3 is fixedly connected inside the protective shell 2. A square shell 4 is installed on the front side of the outer shell 1. The square shell 4 serves as the mounting carrier for the protective mechanism 5, and the protective mechanism 5 is installed inside the square shell 4.

[0034] The fixing mechanism 3 includes an electric push rod 31, which serves as the drive source. The drive end of the electric push rod 31 is fixedly connected inside the protective shell 2. A push shaft 32 is fixedly connected to the drive end of the electric push rod 31. The push shaft 32 transmits the power of the electric push rod 31 to the push block 33. When the electric push rod 31 extends or retracts, it drives the push shaft 32 to move synchronously. The push block 33 is fixedly connected to the outside of the push shaft 32. The push block 33 moves under the drive of the push shaft 32. Its function is to push the rotating shaft 34, thereby driving the connecting rod 35 to move. It is an intermediate link in the power transmission. The rotating shaft 34 is fixedly connected to the outside of the push block 33. The rotating shaft 34 is fixed to the push block 33. 3. Externally, a pivot point is provided for the connecting rod 35, allowing the connecting rod 35 to rotate around the rotating shaft 34. The connecting rod 35 is rotatably connected to the outside of the rotating shaft 34. The connecting rod 35 connects the rotating shaft 34 and the fixed shaft 36, playing the role of power transmission and motion conversion, converting the linear motion of the pushing block 33 into the rotational motion of the rotating assembly 37. The other end of the connecting rod 35 is fixedly connected to the fixed shaft 36. The fixed shaft 36 connects the connecting rod 35 and the rotating assembly 37, transmitting the motion of the connecting rod 35 to the rotating assembly 37, and providing a mounting and rotational foundation for the rotating rod 371. The rotating assembly 37 is fixedly connected to the outside of the fixed shaft 36.

[0035] The rotating assembly 37 includes a rotating rod 371, which is the main rod-shaped structure of the rotating assembly 37. Driven by the fixed shaft 36, the rotating rod 371 rotates, causing the locking blocks 374 at both ends and related components to move. One end of the rotating rod 371 is fixedly connected to the outside of the fixed shaft 36. A second rotating shaft 372 is rotatably connected to the inside of the rotating rod 371. The second rotating shaft 372 provides a fulcrum for the rotation of the rotating rod 371, allowing the rotating rod 371 to rotate stably around the second rotating shaft 372. A support frame 373 is fixedly connected to the outside of the second rotating shaft 372. The support frame 373 supports the rotating rod 371, ensuring its stability during rotation. It also connects the protective shell 2 and the outer shell 1, enhancing the overall structural stability. A locking block 374 is fixedly connected to the other end of the rotating rod 371. The locking block 374, in conjunction with the fixing block 375, secures the square shell 4. When the locking block 374 engages with the fixing block 375, the square shell 4 is fixed; when the locking block 374 disengages from the fixing block 375, the square shell 4 can be released. The fixing block 375 is mounted on the outside of the locking block 374. 75 cooperates with the locking block 374 to provide a fixing point for the square shell 4. Its top is connected to the square shell 4. The fixing state of the square shell 4 is controlled by the locking or unlocking of the locking block 374. The inside of the square shell 4 is fixedly connected to the top of the fixing block 375. The fixing block 375 cooperates with the locking block 374 to provide a fixing point for the square shell 4. The front side of the protective shell 2 is fixedly connected to the rear side of the support frame 373. The support frame 373 supports the rotating rod 371. The top of the support frame 373 is fixedly connected to the inner wall of the outer shell 1. The outer shell 1 serves as an auxiliary support for the support frame 373. The external rotatable connection of the push block 33 to one end of the connecting rod 35 provides support. The push block 33 is the intermediate link for power transmission. The other end of the connecting rod 35 is fixedly connected to one end of the rotating rod 371. The rotating rod 371 drives the locking blocks 374 and related components at both ends to move. The rear side of the rotating rod 371 is fixedly connected to the drive end of the electric push rod 31. The outer side of the rotating rod 371 is rotatably connected to the inner wall of the support frame 373. The support frame 373 provides support for the rotating rod 371 and ensures the stability of the rotating rod 371 during rotation.

[0036] Specifically, when it is necessary to fix the square shell 4, the electric push rod 31 starts and retracts, driving the push shaft 32 connected to its drive end to move towards the electric push rod 31. The movement of the push shaft 32 drives the push block 33 to move synchronously. The push block 33 drives the external rotating shaft 34 to move, causing the connecting rod 35 to rotate around the rotating shaft 34 as the fulcrum. The rotation of the connecting rod 35 is transmitted to the rotating rod 371 through the fixed shaft 36, causing the rotating rod 371 to rotate towards the fixed block 375 around the rotating shaft 372 as the center. This causes the locking block 374 at the other end of the rotating rod 371 to engage with the fixed block 375, thereby fixing the square shell 4 in the current position. Throughout the process, the support frame 373 provides stable support for the rotating rod 371, ensuring the stability of the rotation trajectory of the rotating rod 371.

[0037] Reference Figure 1 , Figure 2 and Figure 4 The protective mechanism 5 includes a protective wear-resistant layer 51, made of high-toughness food-grade PP material. This outermost layer directly contacts the interior of the square shell 4, primarily providing external protection. Its surface possesses strong wear resistance, resisting friction, collisions, and other external forces that may occur during daily use, preventing damage to the internal structure of the protective mechanism 5 from affecting its performance. Simultaneously, it prevents external dust, moisture, and other impurities from entering the interior of the protective mechanism 5, providing a stable protective barrier for the inner structure. A structural support layer 52 is fixedly connected to the bottom of the protective wear-resistant layer 51. This structural support layer 52 is made of environmentally friendly high-density EVA foam and is located between the protective wear-resistant layer 51 and the interactive functional layer 53, serving as a crucial structural support. The entire protective mechanism 5 provides a stable framework, ensuring that it is not easily deformed when subjected to external pressure or impact, maintaining the integrity of the overall structure. Furthermore, it disperses external pressure, reducing direct impact on the interactive functional layer 53 and indirectly protecting its functional stability. The interactive functional layer 53 is fixedly connected to the bottom of the structural support layer 52. The interactive functional layer 53 is made of food-grade soft silicone. As the innermost layer of the protective mechanism 5, the interactive functional layer 53 is the part that directly contacts children, and its core function is to realize the interactive function of the operating box. Its surface design is typically adapted to the operational needs of preschool children, guiding them to engage in mathematical thinking-related activities through tactile feedback and shape adaptation. Simultaneously, it provides children with a comfortable contact experience, enhancing safety and enjoyment during use, and facilitating the smooth implementation of mathematical thinking enlightenment activities. The outer protective wear-resistant layer 51 is installed inside the square shell 4.

[0038] Specifically, when the square shell 4 is subjected to external friction or impact, the outermost protective wear-resistant layer 51 first comes into contact with the external force, directly resisting wear and impact using its own properties, blocking or absorbing most of the external force, and reducing the intensity of the external force transmitted inward. The residual external force after initial buffering by the protective wear-resistant layer 51 is transmitted to the structural support layer 52. The structural support layer 52, with its own structural characteristics, further disperses and absorbs these external forces, preventing the external force from concentrating on a single point and causing deformation of the protective mechanism 5. At the same time, its stable structural form ensures that the protective wear-resistant layer 51 and the interactive function layer 53 can maintain a relatively stable positional relationship, providing a structural foundation for the function of each layer. The interactive function layer 53 is located on the innermost side, and under the dual protection of the protective wear-resistant layer 51 and the structural support layer 52, it can avoid external damage and always maintain good interactive performance. When children operate it, they directly contact the interactive function layer 53. Its design characteristics can guide children to complete corresponding mathematical thinking training actions, while the outer two layers of structure continuously provide protection for it, ensuring the stable realization of the interactive function.

[0039] The implementation principle of this application embodiment is as follows: When the drawer of the operation box for storing tools is prevented from slipping, the electric push rod 31 is activated. When the electric push rod 31 is pushed, it drives the push shaft 32 to move. The push shaft 32 drives the push block 33 to move. The push block 33 drives the rotating shaft 34 to rotate the connecting rod 35. Since the connecting rod 35 is fixed to the fixed shaft 36, the rotation of the connecting rod 35 drives the rotating rod 371 to rotate. The rotation of the rotating rod 371 drives the rotating shaft 372 to rotate. At the same time, the locking block 374 on the other end of the rotating rod 371 is locked to the fixed block 375. This can prevent the drawer from sliding and tipping over, and the teaching aids from falling, reducing the risk of accidental injury to children. In addition, during operation, the position of the drawer can be kept stable. Children do not need to be distracted by holding the drawer or picking up teaching aids. They can smoothly take out and put in materials, and can also cultivate storage habits. In addition, in terms of concentration, it eliminates unexpected interference, helps children concentrate on exploring mathematical knowledge, and improves the effect of thinking training. At the same time, it reduces friction and collision of the drawer, extends the service life of the operation box, and ensures that the teaching aids are stable and usable.

[0040] When the control box requires safety protection, the outermost protective wear-resistant layer 51 is made of high-toughness food-grade PP material and is directly installed inside the square shell 4. With its excellent impact resistance and wear resistance, it blocks external force erosion and forms a synergistic protection through a tight fit with the square shell 4, reducing the inward transmission of impact energy. The middle structural support layer 52 is made of environmentally friendly high-density EVA foam, which provides rigid support to maintain the overall structural shape and absorbs the remaining impact energy through the compression deformation of the porous structure, achieving secondary buffering and pressure reduction. The innermost interactive functional layer 53 is made of food-grade soft silicone, which comes into direct contact with the user. Its safety properties, high elasticity, and anti-slip properties ensure that it is non-toxic and harmless, fits tightly, and is stable and anti-slip during contact. It avoids damage to the object through flexible protection. The three-layer structure works in a progressive manner to comprehensively ensure protective performance and interactive safety.
