Detailed Implementation

[0028] This invention designs a reinforced magnetic sheet with a size of 20-90cm, which can be used in dollhouses or other structures with internal movement.

[0029] like Figures 1 to 6 The image shown is an embodiment of this utility model.

[0030] The reinforced magnetic sheet includes a cover plate 1 and a magnet. The cover plate 1 is integrally injection molded by a mold. This utility model has multiple reinforcing members on the inner side of the cover plate 1.

[0031] The cover plate 1 of this utility model includes an end face 1a and a connecting face 1b. The connecting face 1b is designed in an arc shape and is located at the edge of the end face 1a. The arc shape effectively avoids the sharp edges of the magnetic sheet, thereby reducing the possibility of accidental injury to children during play. This design makes the magnetic sheet more suitable for children, and parents can let their children play and explore with greater peace of mind. At the same time, the arc shape makes the magnetic sheet visually more rounded and softer, and the overall appearance is more aesthetically pleasing. This attractive appearance can attract children's attention and stimulate their curiosity and desire to explore. Moreover, the arc-shaped magnetic sheet is more flexible when splicing, making it easier to build various shapes and structures. This flexibility helps to stimulate children's creativity and imagination, allowing them to learn more knowledge and skills while playing. The end face 1a and the connecting face 1b form an inner cavity. The end faces 1a of the two cover plates 1 are a certain distance apart, and the connecting faces 1b of the two cover plates 1 are spliced ​​together to seal the connection between the two cover plates 1.

[0032] This invention fixes multiple reinforcing ribs 2a between the end face 1a and the connecting surface 1b. The reinforcing ribs 2a are one type of reinforcement, used to increase the structural strength of the end face 1a and the connecting surface 1b, and to reduce stress concentration between them, preventing deformation and effectively improving the deformation resistance and load-bearing capacity of the magnetic sheet. The reinforcing ribs 2a can fix the end face 1a to one of the connecting surfaces 1b, or to both connecting surfaces 1b.

[0033] When reinforcing rib 2a is fixed to end face 1a and the two connecting surfaces 1b, reinforcing rib 2a has a certain length. At this time, reinforcing rib 2b is set between end face 1a and reinforcing rib 2a, arranged in a cross shape with reinforcing rib 2a. Reinforcing rib 2b is one type of reinforcement, strengthening reinforcing rib 2a and further increasing the structural strength of end face 1a and connecting surfaces 1b, thus improving the load-bearing capacity of cover plate 1. The setting of reinforcing ribs 2a and 2b can improve the strength and rigidity of the magnetic sheet, increasing its stability during use and allowing it to better adapt to the needs of these complex application scenarios. Moreover, reinforcing ribs 2a and 2b can also serve as flow channels during the injection molding process, promoting the filling and uniform distribution of injection molding material and improving the production quality of the magnetic sheet.

[0034] The inner side of the cover plate 1 is provided with connecting posts 3, and the number of connecting posts 3 is designed according to the size of the cover plate 1. One of the cover plates 1 has a connecting post hole 1 for its connecting post 3, and the connecting post 3 of the other cover plate 1 is inserted into the connecting post hole 1, so that the connecting posts 3 of the two cover plates 1 are interlocked to connect the two cover plates 1. In this utility model, a reinforcing rib 2c is fixed to the inner side of the cover plate 1 and the connecting post 3. The reinforcing rib 2c is one of the ways to strengthen the connection, which increases the load-bearing capacity of the connecting post 3 and prevents the connecting post 3 from breaking when it is inserted.

[0035] When fixing the two cover plates 1, ultrasonic welding is used at the contact point of the connecting surface 1b, which has the following technical effects:

[0036] (1) Ultrasonic welding technology can complete the welding of a product in an average of only 1.1 to 2.5 seconds, which significantly improves production efficiency. Moreover, ultrasonic welding can achieve the strength of the plastic parts themselves, making the magnetic sheets more robust, durable and less prone to damage.

[0037] (2) Magnetic sheets produced using ultrasonic welding technology maintain a consistent appearance, reducing defects caused by uneven welding. Furthermore, ultrasonic welding eliminates the need for glue or other adhesives, reducing the use of harmful substances and making the magnetic sheets safer and more environmentally friendly, suitable for children. Moreover, the magnetic sheets are tightly connected through ultrasonic welding, preventing them from easily falling off or breaking, ensuring the integrity and stability of the toy.

[0038] (3) The surface of the ultrasonically welded magnetic tiles is smooth and burr-free, with a comfortable feel, making them suitable for young children to grasp. Moreover, the magnetic tiles are connected by magnetic force, making the assembly process easier and simpler, suitable for children to creatively build.

[0039] (4) It enables the magnetic sheets to be made of environmentally friendly materials, such as ABS plastic, which is recyclable and conducive to resource conservation and environmental protection.

[0040] This utility model involves installing a customized plate between two cover plates 1. The cover plates 1 are provided with through holes 9, and the plate and through holes 9 are correspondingly arranged. The plate is a PC sheet 7. PC sheet 7 has excellent physical and chemical properties, and features high transparency, high impact strength, and good heat resistance, making PC sheet 7 an ideal material for customized logos. Through specific technology, logos, patterns, etc. can be customized on PC sheet 7, and users can see the customized information of PC sheet 7.

[0041] The inner side of the cover plate 1 is equipped with a mounting component, which is a connecting post 2 4. The number of connecting posts 2 4 is designed according to the size of the cover plate 1. One of the connecting posts 2 4 of the cover plate 1 has a connecting post hole 2, and the connecting post 2 4 of the other cover plate 1 is inserted into the connecting post hole 2, so that the connecting posts 2 4 of the two cover plates 1 are interlocked. The PC sheet 7 has a mounting hole 8, and the connecting post 2 4 passes through the mounting hole 8. When the two cover plates 1 are removed, the PC sheet 7 can be replaced in time to meet various customized needs, and the PC sheet 7 can also be processed separately. The inner side of the cover plate 1 and the connecting post 2 4 are fixed with a reinforcing rib 4 2d. The reinforcing rib 4 2d is one of the reinforcement methods to increase the load-bearing capacity of the connecting post 2 4 and prevent the connecting post 2 4 from breaking when it is inserted.

[0042] The inner side of the cover plate 1 is provided with a mounting frame 5, which forms a mounting groove 6. The magnet is installed in the mounting groove 6. The magnet is preferably cylindrical, with one end being the N pole and the other end being the S pole, so that the cover plate 1 is magnetic. When the magnetic pieces are assembled, they will rotate and connect on their own. A reinforcing rib 5 is fixed to the inner side of the mounting groove 6. The reinforcing rib 5 is one type of reinforcement, which increases the structural strength of the mounting groove 6 and meets the requirements for the embedded installation of the magnet.

[0043] The cover plate 1 is a light-transmitting cover plate, preferably made of ABS plastic, and has the following technical advantages:

[0044] (1) ABS plastic is a widely used engineering plastic. Due to its excellent impact resistance and chemical stability, it is widely used in toy manufacturing. It is non-toxic, odorless, and does not release harmful substances, posing no threat to children's health. At the same time, the edges and corners of ABS plastic can be rounded and smoothed to avoid scratching hands, further ensuring the safety of children when using magnetic tiles.

[0045] Furthermore, ABS plastic has high strength and toughness, capable of withstanding significant external forces and impacts, and is not easily damaged. This allows the magnetic tiles to maintain their integrity for a longer period of use, extending the toy's lifespan.

[0046] (2) ABS plastic has good processing performance and can be used to make magnetic sheets with a frosted texture. This texture not only makes the magnetic sheets feel more comfortable to the touch, but also enhances the overall texture of the toy.

[0047] ABS plastic magnetic tiles also have advantages in terms of color matching and light transmittance. High-quality ABS plastic magnetic tiles usually have a wide range of color choices, and the colors are bright, long-lasting, and not easy to fade. At the same time, the good light transmittance of ABS plastic allows the magnetic tiles to present beautiful light and shadow effects under light, increasing the fun and visual appeal of the toys.

[0048] (3) The construction of magnetic tiles is very flexible and can exercise children's trial and error ability, construction ability and spatial awareness. In the process of building magnetic tiles, children need to think about how to splice them, how to adjust the angle and position, etc., which helps to improve their spatial cognition and logical thinking ability.

[0049] Magnetic tiles incorporate many knowledge points, such as the physical concepts of magnetism, the balance of forces, and spatial geometry. Children can subtly learn these concepts while playing, enhancing their scientific literacy and overall abilities.

[0050] A light-emitting element is provided on the inner side of the cover plate 1. The light-emitting element is a light strip 11, and the light from the light strip 11 can pass through the cover plate 1 to provide brightness. This has the following technical effects:

[0051] (1) Under light, it can present a colorful effect. This effect is especially obvious under sunlight or lamplight, making the model built with magnetic tiles like a work of art, full of visual impact.

[0052] Moreover, when the magnetic sheet rotates or moves under light, the light inside it will also present different colors and brightness as the angle changes, and this dynamic effect makes the magnetic sheet more attractive.

[0053] (2) The light-emitting effect of magnetic tiles provides children with more room for imagination. They can use magnetic tiles to build various shapes and display different visual effects through light, thereby stimulating their creativity and imagination.

[0054] Magnetic tiles can also be used as props for light and shadow games. Children can observe the reflection and refraction of light on the magnetic tiles by adjusting their angle and position under sunlight or lamplight, further exploring the mysteries of light and shadow.

[0055] (3) The light-emitting effect of magnetic tiles makes them suitable for use as interior decorations. Children can build various shapes with magnetic tiles and place them on bookshelves, windowsills, or bedside tables to add a unique artistic atmosphere to the room.

[0056] Furthermore, magnetic tiles can also serve as an educational tool. By building models with magnetic tiles, children can learn basic concepts such as color, shape, and space, and explore the mysteries of science by observing the reflection and refraction of light.

[0057] A battery is located on the inner side of the cover plate 1, supplying power to the light strip 11. This invention can be achieved by providing a fixing groove 12 in the cover plate 1, installing the battery 13 in the fixing groove 12, and then providing a battery compartment cover at the fixing groove 12 for easy battery replacement; alternatively, a snap-fit ​​method can be used to directly fix the battery 13 to the inner side of the cover plate 1. The installation method of the battery 13 in this invention is not limited to the above two methods; other fixing methods can be used to fix the battery 13 to the inner side of the cover plate 1. When installing the battery, it should be correctly installed according to the positive and negative markings.

[0058] The outer surface of the cover plate 1 is provided with multiple grooves 10. The grooves 10 are recessed inward to facilitate children's hands to grasp the magnetic sheet. Moreover, the design of the grooves 10 can also increase the aesthetics of the magnetic sheet.

[0059] In Embodiment 1, the cover plate 1 is designed to be square, which makes the magnetic sheet square as well.

[0060] like Figure 7 The image shown is a second embodiment of this utility model.

[0061] Based on the structure of Embodiment 1 of this utility model, the shape of the cover plate 1 is changed and designed as a trapezoid, so that the shape of the magnetic sheet is also trapezoidal.

[0062] like Figure 8 The image shown is a third embodiment of this utility model.

[0063] Based on the structure of Embodiment 1 of this utility model, the shape of the cover plate 1 is changed and designed as a triangle, so that the magnetic sheet is triangular in shape.

[0064] Magnetic building blocks are a creative and educational toy. They come in various shapes, including triangles, squares, and trapezoids, and chamfers can be added to these shapes, with the chamfer size varying. Specific dimensions can be designed as follows: square blocks with a side length of 420mm and a thickness of 13mm; equilateral triangle blocks with a side length of 400-405mm and a thickness of 13mm; and isosceles trapezoid blocks with a base length of 820-825mm, a height of 360-365mm, and a thickness of 13mm. The combination and arrangement of triangular, square, and trapezoidal blocks, where the vertices of the virtual intersections of the three types coincide, can stimulate players' creativity and imagination, allowing them to discover new building methods and structures through continuous trial and error. Simultaneously, the process of building with magnetic blocks can develop players' hands-on skills, spatial imagination, and logical thinking abilities, positively impacting children's intellectual development. Moreover, the diversity and variability of magnetic tiles make the building process fun, and players can experience a sense of accomplishment and satisfaction in the process.

[0065] The method for manufacturing reinforced magnetic sheets includes the following steps:

[0066] S1. Install the mold onto the injection molding machine, ensuring the mold is securely installed and accurately positioned. Inject molten material into the mold, filling the mold cavity. The cover plate of this invention is integrally injection molded using the mold. During the injection molding process, control the temperature, pressure, and injection speed. After injection molding, allow the material in the mold to cool naturally to room temperature and solidify. Once the material in the mold has completely solidified, open the mold and remove the injection-molded cover plate.

[0067] The removed cover plate can be visually inspected, its dimensions measured, and its performance tested to ensure that it meets design requirements.

[0068] S2. Install the magnet in the inner cavity of the cover plate 1, ensuring that the position and orientation of the magnet are correct.

[0069] S3. Process the board body separately and customize the board body. The board body uses PC sheet 7. According to the size of the cover plate 1, the PC sheet 7 of the set size can be laser cut. Then, the logo, pattern, etc. are customized on the PC sheet 7. Then the board body is set between the two cover plates 1.

[0070] S4. The two cover plates 1 are spliced ​​together, and the connecting posts 3 on the inner side of the cover plates 1 are inserted into each other, so that the two cover plates 1 are fixedly connected.

[0071] The edges of the two cover plates 1 can be further fixed by ultrasonic welding, specifically including the following steps:

[0072] 1) Start the ultrasonic welding machine. Under the action of air pressure, the welding head applies the set pressure to the edges of the two cover plates 1.

[0073] 2) The ultrasonic generator converts electrical energy into high-frequency vibration waves, which are transmitted to the edge of the cover plate 1 through the transducer and welding head. The welding head vibrates at a frequency of 20,000 to 40,000 times per second, generating frictional heat.

[0074] 3) Under the combined action of high-frequency vibration and pressure, the edge of cover plate 1 begins to melt and form a molten pool. The material in the molten pool fuses between molecular layers, thereby achieving welding between the two cover plates 1.

[0075] 4) After welding is complete, turn off the ultrasonic welding machine and allow the material in the molten pool to cool and solidify naturally to obtain the desired magnetic sheet. During the cooling process, avoid applying external force to the welded area to prevent affecting the welding quality.

[0076] 5) Conduct a visual inspection of the welded magnetic sheets to ensure that the welded areas are flat, smooth, and free of cracks or defects. Then, perform performance tests on the welded magnetic sheets, such as tensile tests and magnetic property tests, to ensure they meet the usage requirements. If any defective products are found, magnetic sheets with substandard welding quality should be reworked or scrapped.

[0077] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
