Description

Technical Field

[0001] This application relates to the field of building block toy technology, and more particularly to a magnetic building block toy. Background Technology

[0002] Building blocks are a classic tool for early childhood education and are loved by both parents and children. Currently, some building blocks on the market have electronic functions, such as incorporating LEDs inside to enhance playability. However, some lighting control technologies in building block technology have limitations.

[0003] One type of illuminated building block uses physical button control, typically requiring a mechanical button on the surface of the block, which the user presses to trigger the light. This external mechanical button design somewhat compromises the overall integrity and aesthetics of the building block's appearance; furthermore, as a moving part, the button is prone to damage or malfunction due to frequent pressing, and it also complicates the internal structure of the building block, placing more stringent requirements on block assembly, waterproof sealing design, internal space layout, and center of gravity control.

[0004] Another type of light-up building block uses a contact-based trigger, relying on the contact points when two blocks are joined to achieve light emission. This method depends on strict joining posture and physical contact, resulting in insufficient playability and flexibility. Furthermore, the exposed contacts are prone to wear, poor contact, or damage, leading to poor stability and durability. Utility Model Content

[0005] In view of this, this application provides a magnetic building block toy, which aims to solve the problems of existing light-up building blocks, such as complex structure, inconvenient assembly, poor water resistance, and unfriendly triggering methods.

Detailed Implementation

[0053] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0054] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present. When a component is considered to be "located" to another component, it can be directly mounted on the other component or there may be an intervening component present.

[0055] Unless otherwise stated, the term "multiple" as used herein refers to two or more.

[0056] The terms “first”, “second”, etc., are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implying the quantity, specific order, or primary and secondary relationship of the indicated technical features.

[0057] The term "perpendicular" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately perpendicular. For example, in numerical terms, perpendicularity can refer to the angle between two straight lines within the range of 90° ± 10°, the dihedral angle between two planes within the range of 90° ± 10°, or the angle between a straight line and a plane within the range of 90° ± 10°.

[0058] The term "parallel" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately parallel. For example, in numerical terms, parallel can refer to the angle between two straight lines within the range of 180° ± 10°, the dihedral angle between two planes within the range of 180° ± 10°, or the angle between a straight line and a plane within the range of 180° ± 10°.

[0059] It should be understood that the dimensions of the components shown in the accompanying drawings are provided for better understanding and easier description, and this application is not limited to the dimensions shown in the drawings. For the sake of clarity, elements irrelevant to the description have been omitted from the details of this specification.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0061] The following description, in conjunction with the accompanying drawings, outlines some embodiments of this application. Unless otherwise specified, the embodiments and features described below can be combined with each other. Furthermore, the dashed lines in the accompanying drawings do not represent physical structures and are merely for distinguishing different features.

[0062] Please see Figures 1 to 3 Some embodiments of this application provide a magnetic building block 100, which includes a first building block 10. The first building block 10 includes a first housing 11 and at least one first magnet 12, a first circuit board 13, a first sensor 14, a first light-emitting module 15 and a first power module 16 disposed in the first housing 11.

[0063] The first magnet 12 is positioned within the first limiting region 111 of the first housing 11 to ensure that the first magnet 12 does not move to an undesirable area. The first sensor 14 is electrically connected to the first circuit board 13, the first light-emitting module 15 is electrically connected to the first circuit board 13, and the first power module 16 is electrically connected to the first circuit board 13, the first sensor 14, and the first light-emitting module 15. The first power module 16 is used to supply power to the first circuit board 13, the first sensor 14, and the first light-emitting module 15.

[0064] When a magnet approaches the first sensor 14 of the first block 10, the first sensor 14 can sense the magnetic signal of the approaching magnet and output a first trigger signal to the first circuit board 13 when the preset trigger condition is met, so that the first circuit board 13 controls the first light-emitting module 15 to emit light.

[0065] It is understandable that the preset trigger condition could be that the distance between the first sensor 14 and the external magnet reaches a threshold, which allows the first sensor 14 to stably receive magnetic signals from the external magnet. The first power module 16 can be a removable battery, such as a button cell battery. Figure 2 and Figure 3 The first sensor 14 can be one, or it can be two or more.

[0066] Compared to traditional light-emitting building blocks that require physical contact or buttons to trigger, the magnetic induction-triggered light-emitting method of the magnetic building block 100 in the above embodiment improves the overall sealing performance of the magnetic building block 100, significantly enhancing its waterproof sealing performance and reducing the risk of moisture damage to the internal circuitry. It also simplifies the building block structure, eliminating the need for complex spring-loaded mechanisms and button positioning structures, thus improving assembly and production efficiency. Furthermore, the first circuit board 13 can be more flexibly arranged within the first housing 11, facilitating optimized center of gravity distribution. In addition, it reduces exposed contacts, minimizing the risk of damage to the light-emitting function due to damage to exposed contacts.

[0067] In some embodiments, the first sensor 14 is configured to sense a magnetic signal generated by the first magnet 12 of the other magnetic block 100 when the first block 10 and the other magnetic block 100 are close to each other, and to output a first trigger signal to the first circuit board 13 when the magnetic signal meets a preset trigger condition, so that the first circuit board 13 controls the first light-emitting module 15 to emit light.

[0068] In some embodiments, the other magnetic block 100 referred to herein can be any block with a magnet, regardless of whether it has an luminous function. This allows a single magnetic block 100 to work with any other magnetic block to emit light, thus expanding product compatibility.

[0069] In some other embodiments, the first sensor 14 is configured to sense a magnetic signal generated by the magnetic component when the first block 10 and the magnetic component are close to each other, and to output a first trigger signal to the first circuit board 13 when the magnetic signal meets a preset trigger condition, so that the first circuit board 13 controls the first light-emitting module 15 to emit light.

[0070] In some embodiments, please refer to Figure 17 The magnetic component mentioned here can be any magnetic object, such as a doll, animal model, vehicle accessory with a built-in magnet, or simply a magnetic block. The first sensor 14 senses the magnetic signal generated by the magnetic component when the first block 10 and the magnetic component approach each other and triggers light emission. This design expands the application of the magnetic block 100 from between blocks to between blocks and various magnetic toy accessories, providing more possibilities for product play design. Children can explore different combinations and observe which items can trigger the magnetic block 100 to light up, increasing the fun of exploration.

[0071] Please see Figure 2 , Figures 4 to 6 This application also provides a magnetic building block toy 1000 in some embodiments. The magnetic building block toy 1000 includes at least one set of magnetic building blocks 100. Each set of magnetic building blocks 100 includes a first building block 10 and a second building block 20. The first building block 10 includes a first housing 11 and at least one first magnet 12, a first circuit board 13, a first sensor 14, a first light-emitting module 15, and a first power supply block disposed within the first housing 11. The second building block 20 includes a second housing 21 and at least one second magnet 22 disposed within the second housing 21. The first magnet 12 is positioned in a first limiting region 111 within the first housing 11. The first sensor 14 is electrically connected to the first circuit board 13, the first light-emitting module 15 is electrically connected to the first circuit board 13, the first sensor 14, and the first light-emitting module 15, and the first power supply module 16 is electrically connected to the first circuit board 13, the first sensor 14, and the first light-emitting module 15, for supplying power to the first circuit board 13, the first sensor 14, and the first light-emitting module 15. The second magnet 22 is positioned in the limiting region within the second housing 21. The first sensor 14 is configured to sense the magnetic signal generated by the second magnet 22 when the first block 10 and the second block 20 are close to each other, and output a first trigger signal to the first circuit board 13 when the magnetic signal meets the preset trigger conditions, so that the first circuit board 13 controls the first light-emitting module 15 to emit light.

[0072] In some embodiments, the second building block 20 in the above embodiments may be provided with components such as a second circuit board 23, a second sensor 24, a second light-emitting module 25, and a second power supply module 26 to emit light. In other embodiments, the second building block 20 in the above embodiments may not be provided with components such as a second sensor 24, a second light-emitting module 25, and a second power supply module 26 to emit light and therefore cannot emit light.

[0073] In some embodiments, please refer to Figure 4 and Figure 18 The first light-emitting module 15 is configured to emit light before the first block 10 and the second block 20 come into magnetic contact, achieving an interactive feature that can be triggered upon proximity. It is understood that in these embodiments, the design ensures that the first light-emitting module 15 is triggered to light up when the first block 10 approaches the second block 20, or when the second block 20 approaches the first block 10, or when the first block 10 and the second block 20 approach each other, even if the first block 10 and the second block 20 have not yet made contact, providing the user with immediate visual feedback.

[0074] In actual building, this pre-illumination function serves as an excellent guide, indicating to children that the blocks are aligned and ready for assembly. It also allows children to immediately know whether the blocks they hold are lit or what color they are. Furthermore, compared to physical buttons or touch-sensitive triggering technologies, this design eliminates the need to assemble the blocks into a specific position to illuminate, and avoids the need to disassemble the assembled blocks to determine if they light up, thus improving ease of play. Simultaneously, this proximity-triggered design avoids the problem of requiring forceful pressing in traditional technologies and reduces the risk of poor contact. Furthermore, in some application scenarios, multiple second blocks 20 have already been stacked into a certain shape. When the first block 10 approaches, that is, before the first block 10 and the second block 20 have come into contact, the first block 10 illuminates to indicate the color of the first block 10 held by the child. If it is not the color the child expects, the child can immediately put down the first block 10 and pick up other first blocks 10. In other words, if the first block 10 and the second block 20 have already come into contact, the child needs to use one hand to press down or hold the second block 20 that has already been placed in the position, and then use the other hand to pull away the first block 10 that has been attached together. Otherwise, the block toy that has already been arranged in a shape is easy to deform or even collapse, thus improving the convenience of stacking block toys. In addition, when a first block 10 and a second block 20 are close to each other, the first block 10 and the second block 20 will trigger each other to emit light because they are close enough. Other blocks that are some distance away from the first block 10 and the second block 20 will not trigger to emit light because they are far away. That is, only blocks that are close to each other will trigger to emit light.

[0075] In other embodiments, please refer to Figure 7 The first light-emitting module 15 is configured to emit light after the first block 10 and the second block 20 come into contact with each other through magnetic adsorption.

[0076] In some embodiments, please refer to Figures 2 to 7 Some embodiments of this application also provide a magnetic building block toy 1000, which includes at least one set of magnetic building blocks 100 that can cooperate with each other. Each set of magnetic building blocks 100 includes a first building block 10 and a second building block 20.

[0077] The first building block 10 includes a first housing 11, and a first magnet 12, a first circuit board 13, a first sensor 14, a first light-emitting module 15, and a first power module 16, all disposed within the first housing 11. At least one first magnet 12 is provided. The first magnet 12 is positioned within a first limiting region 111 of the first housing 11 to provide magnetic attraction. The first sensor 14 is electrically connected to the first circuit board 13 to sense an external magnetic field. The first light-emitting module 15 is electrically connected to the first circuit board 13 to emit light upon receiving a trigger signal. The first power module 16 is electrically connected to the first circuit board 13, the first sensor 14, and the first light-emitting module 15 to supply power to them.

[0078] The second building block 20 includes a second housing 21, and a second magnet 22, a second circuit board 23, a second sensor 24, a second light-emitting module 25, and a second power module 26 disposed within the second housing 21. At least one second magnet 22 is provided. The second magnet 22 is positioned within a second limiting region 211 of the second housing 21 to provide magnetic attraction. The second sensor 24 is electrically connected to the second circuit board 23 to sense an external magnetic field. The second light-emitting module 25 is electrically connected to the second circuit board 23 to emit light upon receiving a trigger signal. The second power module 26 is electrically connected to the second circuit board 23, the second sensor 24, and the second light-emitting module 25 to supply power to these components.

[0079] The first sensor 14 is configured to sense the magnetic signal generated by the second magnet 22 when the first block 10 and the second block 20 are close to each other, and output a first trigger signal to the first circuit board 13 when the magnetic signal meets a preset trigger condition, so that the first circuit board 13 controls the first light-emitting module 15 to emit light; the second sensor 24 is configured to sense the magnetic signal generated by the first magnet 12 when the first block 10 and the second block 20 are close to each other, and output a second trigger signal to the second circuit board 23 when the magnetic signal meets a preset trigger condition, so that the second circuit board 23 controls the second light-emitting module 25 to emit light.

[0080] In the above embodiment, the first building block 10 and the second building block 20 are brought close together to trigger each other, causing them to emit light when they are close to each other. During production, the first building block 10 and the second building block 20 do not need to be manufactured as separate products; they can be produced on the same production line, simplifying the production process and improving installation efficiency. Simultaneously, because the first building block 10 and the second building block 20 trigger each other, the DIY fun of the product is increased, bringing children a sense of unknown curiosity. When neither the first building block 10 nor the second building block 20 emits light, their shapes are identical. If the stickers on the surfaces of the first building block 10 and the second building block 20 are also identical, then children will not know what color light their first building block 10 and the second building block 20 will emit, creating a sense of mystery.

[0081] More specifically, compared to traditional light-emitting building blocks that require physical buttons or contact points to activate, this embodiment achieves inductive light emission, greatly improving ease of use and fun. By eliminating physical buttons and contact points, the waterproof sealing performance of the building blocks is significantly improved, and the internal circuitry is less susceptible to moisture damage. It also simplifies the building block structure, eliminating the need for complex spring-loaded mechanisms and button positioning structures, thus improving the assembly and production efficiency of the magnetic building blocks 100. Furthermore, the first circuit board 13 can be more flexibly arranged within the first housing 11, facilitating optimized center of gravity distribution. In addition, the number of exposed contacts is reduced, which helps to minimize damage to the light-emitting function due to damage to exposed contacts, and also solves the problem of requiring two building blocks to be arranged in a strictly specific posture to emit light.

[0082] In some embodiments, the first light-emitting module 15 is configured to emit light before the first block 10 and the second block 20 magnetically come into contact, and the second light-emitting module 25 emits light before the first block 10 and the second block 20 magnetically come into contact. Both the first block 10 and the second block 20 have an interactive feature that is triggered upon proximity. This configuration allows the two blocks to automatically emit light as they approach each other, without waiting for them to fully contact or magnetically attach together. When playing in low-light environments, the light emission can help children more accurately align the blocks.

[0083] In some other embodiments, the first light-emitting module 15 is configured to emit light after the first building block 10 and the second building block 20 come into magnetic contact. The second light-emitting module 25 is configured to emit light after the first building block 10 and the second building block 20 come into magnetic contact.

[0084] In some embodiments, the first building block 10 and the second building block 20 have identical structures. This means that the first building block 10 and the second building block 20 are essentially identical in terms of external shape, internal structure, magnet layout, and electronic component configuration, and there is no distinction between male and female as commonly found in traditional connectors. Users do not need to sort or select the building blocks when playing; they can simply pick up any two blocks to match, greatly improving the convenience of play. From a manufacturing perspective, only one set of molds is needed to produce all the building blocks, reducing mold costs and inventory management difficulties, and simplifying the assembly process.

[0085] In some embodiments, please refer to Figure 4 and Figure 7 The first housing 11 has a cubic structure. See also the following for some embodiments. Figure 4 and Figure 7 The second shell 21 has a cubic structure.

[0086] In some embodiments, please refer to Figure 2 and Figure 8 The first housing 11 includes a first box body 11a and a first box cover 11b. The first box body 11a includes a first wall 11a1, a second wall 11a2, a third wall 11a3, and a fourth wall 11a4 connected end to end. The first wall 11a1, the second wall 11a2, the third wall 11a3, and the fourth wall 11a4 enclose a receiving cavity 11d, and the two ends of the receiving cavity 11d form a first opening 11d1 and a second opening 11d2, respectively. The first box cover 11b includes a fifth wall 11b1 and a sixth wall 11b2, which are used to cover and connect to the first opening 11d1 and the second opening 11d2, respectively, thereby sealing the entire first housing 11. It can be understood that the first box cover 11b consists of two independent covers, one of which covers the first opening 11d1 and the other covers the second opening 11d2.

[0087] In some embodiments, please refer to Figure 9 The first housing 11 also includes a first reinforcing rib structure 11c. Four sets of the first reinforcing rib structures 11c are arranged at the connection points between adjacent walls of the first wall 11a1, second wall 11a2, third wall 11a3, and fourth wall 11a4, i.e., at the four corners. The first reinforcing rib structures 11c not only enhance the strength at the corners and prevent housing deformation, but also form a limiting area. The first limiting area 111 can be located at one or both ends of a first reinforcing rib structure 11c for precisely accommodating and positioning the first magnet 12. Specifically, the first magnet 12 can be fixed within the first limiting area 111. In some other embodiments, the first magnet 12 can be flipped within the first limiting area 111. This structural design allows the magnet to be limited to a predetermined position, reducing the risk of unintended displacement during use and ensuring the consistency and reliability of the magnetic attraction effect.

[0088] In some embodiments, the structure of the second housing 21 is the same as that of the first housing 11. For details, please refer to the above description of the first housing 11, which will not be repeated here.

[0089] In some embodiments, please refer to Figure 2 and Figure 8 The first housing 11 has a cubic structure and eight first limiting regions 111. One first sensor 14 is provided and located in one of the first limiting regions 111. Seven first magnets 12 are provided and located in the remaining seven first limiting regions 111. One first circuit board 13 is provided, with the first sensor 14 located on one side of the first circuit board 13. A first power module 16 and a first light-emitting module 15 are both located on the other side of the first circuit board 13. A support portion 11e is provided in the receiving cavity 11d, and the first circuit board 13 and the first power module 16 are located between the support portion 11e and the fifth wall 11b1.

[0090] Understandably, in the layout described in the above embodiment, the first sensor 14 is positioned in one of the limiting areas and is responsible for detecting the external magnetic field. Seven magnets are respectively positioned in the remaining seven limiting areas, providing omnidirectional magnetic attraction, allowing the first block 10 to attract other blocks when approached from any direction. This configuration ensures both magnetic attraction and sensor detection, resulting in more efficient space utilization.

[0091] The first sensor 14 is located on one side of the circuit board, facing the direction to be detected. The first power module 16 and the first light-emitting module 15 can be located on the other side of the first circuit board 13, thus making full use of the space on both sides of the circuit board. The support part 11e supports the first circuit board 13 and the first power module 16, making them stably fixed between the fifth wall 11b1 and the support part 11e. This layout allows the circuit board to be suspended, so even if there are gaps in the housing, even if water enters through the gaps in the first building block 10, the water will flow downwards along the housing and will not directly invade the circuit board area, further improving waterproof performance and reliability.

[0092] It is worth mentioning that the second shell 21 of the second building block 20 can also be configured as a cubic structure, and the second shell 21 includes a second box body and a second box lid. The second shell 21 has eight second limiting areas 211. The specific structure and other settings can be referred to the first building block 10 in the above embodiment, and will not be repeated here.

[0093] In some embodiments, please refer to Figure 2The first sensor 14 is arranged at a distance from the at least one first magnet 12. This arrangement maintains a certain distance between the first sensor 14 and the first magnet 12. This spacing helps reduce magnetic interference from the first magnet 12 of the first block 10 itself to the first sensor 14, ensuring that the first sensor 14 can accurately detect the magnetic field signal generated by the external magnet. By rationally arranging the relative positions of the first sensor 14 and the first magnet 12, the detection performance of the first sensor 14 can be optimized while ensuring the magnetic attraction function.

[0094] In some embodiments, please refer to Figure 5 The second sensor 24 is arranged at a distance from the at least one second magnet 22. This arrangement maintains a certain distance between the second sensor 24 and the second magnet 22. This spacing helps reduce magnetic interference from the second magnet 22 of the second block 20 itself to the second sensor 24, ensuring that the second sensor 24 can accurately detect the magnetic field signal generated by the external magnet. By rationally arranging the relative positions of the second sensor 24 and the second magnet 22, the detection performance of the second sensor 24 can be optimized while ensuring the magnetic attraction function.

[0095] In some embodiments, please refer to Figure 2 and Figure 8 The first housing 11 has a cubic structure, and the first sensor 14 is located at the corner of the first housing 11.

[0096] In some embodiments, please refer to Figure 9 The first housing 11 has a cubic structure, and the first sensor 14 is located in the middle of the side wall of the first housing 11.

[0097] In some embodiments, please refer to Figure 10 The first housing 11 has a cubic structure, and the first sensor 14 is located at the edge of the first housing 11.

[0098] In some embodiments, the second housing 21 has a cubic structure, and the second sensor 24 is disposed at a corner of the second housing 21.

[0099] In some embodiments, the second housing 21 has a cubic structure, and the second sensor 24 is disposed at the middle position of the side wall of the second housing 21.

[0100] In some embodiments, the second housing 21 has a cubic structure, and the second sensor 24 is disposed at the edge of the second housing 21.

[0101] It is understood that, in the above embodiments, the corners refer to the positions of the eight vertices of the cube, the sidewalls refer to any one or more of the first wall 11a1, the second wall 11a2, the third wall 11a3, the fourth wall 11a4, the fifth wall 11b1, and the sixth wall 11b2, and the edges refer to the edges of the cube structure. The corner positions, the middle positions of the sidewalls, and the edge positions mentioned in the above embodiments all have their characteristics, and in actual products, appropriate positions can be selected according to the expected play requirements.

[0102] Taking two identical building blocks aligned, with the sensor of one block corresponding to the magnet of the other block as an example: If the sensor is located at a corner, the block will light up if any one of the three faces of that corner is aligned with the other block; if the sensor is located in the middle of a side wall, the block will light up if the face of that side wall is aligned with the other block; if the sensor is located at an edge, the block will light up if at least one of the two faces of that edge is aligned with the other block.

[0103] The following describes an example of the position setting of the first light-emitting module 15. The position setting of the second light-emitting module 25 can be referred to the first light-emitting module 15, and will not be repeated here.

[0104] In some embodiments, please refer to Figure 11 The first light-emitting module 15 is disposed on the first circuit board 13. For example, the first light-emitting module 15 is a surface-mount light-emitting diode, which is directly soldered to the corresponding position on the circuit board; or the first light-emitting module 15 is an LED, which is fixed to the corresponding position on the circuit board. This design is compact, simple to assemble, and suitable for applications where the light-emitting position is not critical. It can be understood that the first light-emitting module 15 can be disposed on any side of the large surface of the first circuit board 13.

[0105] In other embodiments, please refer to Figure 12 and Figure 13 The first light-emitting module 15 is disposed at a predetermined position on the first housing 11 and electrically connected to the first circuit board 13. This arrangement allows the first light-emitting module 15 to be electrically connected to the first circuit board 13 via wires or a flexible circuit board, enabling the light-emitting points to be positioned at specific corners, edges, or centers of the building block, achieving more precise light distribution. For example… Figure 12 and Figure 13 In the first circuit board 13, the first light-emitting module 15 is disposed on the top of the first circuit board 13 by means of wires or flexible circuit boards, and the first light-emitting module 15 is disposed on the side wall of the first housing 11.

[0106] In some embodiments, please refer to Figures 12 to 14The first light-emitting module 15 is positioned at a predetermined location away from the first circuit board 13 via a corresponding extension connection structure. For example, a thin wire can be used to extend the light-emitting diode to a specific location on the building block. This design allows the first circuit board 13 to be arranged at any location within the first housing 11, while the first light-emitting module 15 can be flexibly laid out according to functional requirements.

[0107] In some embodiments, the first light-emitting module 15 can be a string of LED beads connected by flexible wires. The LED beads can swing freely within the housing, increasing the uncertainty of the light-emitting position and bringing a more random visual effect. To prevent the LED beads from being damaged during shaking, a buffer layer, such as a silicone sleeve or a sponge pad, can be added to the surface of the LED beads.

[0108] In some embodiments, please refer to Figures 12 to 14 The first sensor 14 is positioned at a predetermined location away from the first circuit board 13 via a corresponding extension connection structure. For example, the first sensor 14 can be extended to a specific location on the block using a thin wire. The position of the second sensor 24 can be referenced to that of the first sensor 14, and will not be described in detail here.

[0109] In some embodiments, the first light-emitting module 15 emits light in at least one of the following ways: constant light, flashing light, breathing light, or gradual light.

[0110] In some embodiments, the second light-emitting module 25 emits light in at least one of the following ways: constant light, flashing light, breathing light, or gradual light.

[0111] In some embodiments, please refer to Figure 10 The first magnet 12 is used for magnetic attraction with the second magnet 22, enabling the connection between the building blocks. The first building block 10 also has a first auxiliary magnet 17, which is used to trigger the second sensor 24. The first auxiliary magnet 17 can be dedicated solely to triggering the second sensor 24, without participating in or minimally participating in the magnetic attraction function. This separate design allows the magnetic attraction and triggering functions to be optimized independently: the first magnet 12 used for magnetic attraction can be made of a material with a high magnetic energy product to provide stronger attraction and ensure stable block assembly; the first auxiliary magnet 17 used for triggering can be made of a material with a magnetic field distribution more suitable for detection, or its position and orientation can be adjusted to achieve the best triggering effect. This design further improves the product's performance and reliability.

[0112] In some embodiments, please refer to Figure 15The first magnet 12 is used for magnetic attraction between the second magnet 22, enabling the connection between the building blocks. The second building block 20 also has a second auxiliary magnet 27, which is used to trigger the first sensor 14. The second auxiliary magnet 27 can be dedicated solely to triggering the first sensor 14, without participating in or minimally participating in the magnetic attraction function. This separate design allows the magnetic attraction and triggering functions to be optimized independently: the second magnet 22 used for magnetic attraction can be made of a material with a high magnetic energy product to provide stronger attraction and ensure stable block assembly; the second auxiliary magnet 27 used for triggering can be made of a material with a magnetic field distribution more suitable for detection, or its position and orientation can be adjusted to achieve the best triggering effect. This design further improves the product's performance and reliability.

[0113] In some embodiments, please refer to Figure 10 The magnetic building block toy 1000 also includes a sound playback unit 30. The first building block 10 and the second building block 20 can both be equipped with the sound playback unit 30. Taking the first building block 10 as an example, the sound playback unit 30 is electrically connected to the first circuit board 13 and is configured to play sound when the first sensor 14 outputs a first trigger signal.

[0114] The sound playback unit 30 can emit simple "beep" sounds, or musical clips, animal sounds, word pronunciations, etc., depending on the product's theme and target age group. The combination of sound and light provides dual audiovisual feedback, enhancing the immersion and fun of play. For example, playing cheerful music or animal sounds when the blocks approach helps attract young children's attention and promotes sensory development.

[0115] In some embodiments, please refer to Figure 10 The magnetic building block toy 1000 also includes a vibration unit 40. Both the first building block 10 and the second building block 20 can be equipped with the vibration unit 40. Taking the first building block 10 as an example, the vibration unit 40 is electrically connected to the first circuit board 13 and is configured to vibrate when the first sensor 14 outputs a first trigger signal. For younger children, tactile feedback may be more intuitive than visual and auditory feedback. Vibration when the building blocks are close together can help children understand cause and effect and promote sensory development. The vibration unit 40 can be a miniature vibration motor, small in size and low in power consumption, suitable for integration inside the building blocks.

[0116] In some embodiments, please refer to Figure 10The magnetic building block toy 1000 also includes a magnetic isolation material 50, which can be provided for both the first building block 10 and the second building block 20. Taking the first building block 10 as an example, the magnetic isolation material 50 is placed between the first magnet 12 and the first sensor 14 to reduce the magnetic interference of the first magnet 12 to the first sensor 14. This isolation material can be a magnetically permeable material such as pure iron, used to guide magnetic field lines around the first sensor 14, reducing direct interference to the first sensor 14; or it can be a non-magnetic material with low magnetic permeability such as plastic, aluminum, stainless steel, etc., to reduce the magnetic field strength through physical isolation. The selection and arrangement of the isolation material need to be optimized according to the specific magnetic circuit design to achieve a better interference suppression effect, allowing the sensor and magnet to be placed closer together, thereby optimizing the space utilization inside the building block.

[0117] In some embodiments, the portion of the first housing 11 facing the first sensor 14 is made of a different material than the rest of the first housing 11. For example, the side facing the first sensor 14 may be made of a material with better magnetic permeability to enhance the sensitivity of the first sensor 14 to external magnetic fields; while other portions may be made of conventional materials to ensure the overall strength of the first housing 11. This differentiated design helps to improve the detection sensitivity of the first sensor 14 while maintaining the structural integrity of the first housing 11.

[0118] In some embodiments, the portion of the first housing 11 facing the first sensor 14 has a different thickness than the rest of the first housing 11.

This differentiated design helps to improve the detection sensitivity of the first sensor 14 while maintaining the structural integrity of the first housing 11.

[0119] In some embodiments, the portion of the second housing 21 facing the second sensor is made of a different material than the rest of the second housing 21. For example, the side facing the second sensor 24 may be made of a material with better magnetic permeability to enhance the sensitivity of the second sensor 24 to external magnetic fields; while other portions may be made of conventional materials to ensure the overall strength of the first housing 11. This differentiated design helps to improve the detection sensitivity of the second sensor 24 while maintaining the structural integrity of the first housing 11.

[0120] In some embodiments, the portion of the second housing 21 facing the second sensor 24 has a different thickness than the rest of the second housing 21. For example, the side facing the second sensor can be thinner to enhance the sensitivity of the second sensor 24 to external magnetic fields; while other portions can have a conventional thickness to ensure the overall strength of the second housing 21. This differentiated design helps improve the detection sensitivity of the second sensor 24 while maintaining the structural integrity of the second housing 21.

[0121] In some embodiments, please refer to Figure 3 The first power module 16 includes a removable battery, such as a button cell battery. The removable battery design allows users to easily replace the battery when it is depleted, extending the product's lifespan. In other embodiments, the first power module 16 includes a receiving coil and charging circuitry for wireless charging. The receiving coil can be located inside the housing, charging the built-in rechargeable battery via electromagnetic induction when the first block 10 is placed on the wireless charging base. This design eliminates the hassle of battery replacement and also avoids sealing problems that may result from frequent opening of the housing.

[0122] In some embodiments, please refer to Figure 6 The second power module 26 includes a removable battery, such as a button cell battery. The removable battery design allows users to easily replace the battery when it is depleted, extending the product's lifespan. In other embodiments, the second power module 26 includes a receiving coil and charging circuitry for wireless charging. The receiving coil can be located inside the housing, charging the built-in rechargeable battery via electromagnetic induction when the second block 20 is placed on the wireless charging base. This design eliminates the hassle of battery replacement and also avoids sealing problems that might result from frequent opening of the housing.

[0123] In some embodiments, please refer to Figure 5 The first housing 11 has a charging port 112, such as a common USB-C interface, that is electrically connected to the first power module 16. The first housing 11 also has a sealing cover 113 for sealing the charging port 112, which covers the charging port 112 when not charging to prevent dust and moisture from entering. This design balances charging convenience and sealing reliability. The sealing cover 113 can be made of soft rubber material and fits tightly with the first housing 11 to achieve a good seal. When charging is needed, the user can easily open the sealing cover 113 to insert the charging cable, and then close the sealing cover 113 again after charging is complete.

[0124] In some embodiments, the second housing 21 is provided with a charging port 112 electrically connected to the second power module 26, such as a common USB-C interface.

When charging is needed, the user can easily open the sealing cover 113 to insert the charging cable, and after charging is complete, simply close the sealing cover 113 again.

[0125] In some embodiments, please refer to Figure 4 A first groove 114 is provided on the outer surface of the first housing 11 corresponding to the position of the first sensor 14, which is used to mark the position of the first sensor 14, making it convenient for children to operate and increasing playability. The shape of the first groove 114 can be a circle, ellipse, rectangle, triangle or other regular or irregular shape, and is not specifically limited here.

[0126] In some embodiments, please refer to Figure 4 The outer surface of the second housing 21 has a second groove 212 corresponding to the position of the second sensor 24, which is used to mark the position of the second sensor 24, making it convenient for children to operate and increasing playability.

[0127] In some embodiments, the first sensor 14 is at least one of a Hall sensor, a magnetoresistive sensor, and a reed switch.

[0128] In some embodiments, the second sensor 24 is at least one of a Hall sensor, a magnetoresistive sensor, and a reed switch.

[0129] It should be noted that Hall effect sensors are a common choice, offering advantages such as small size, low power consumption, and high sensitivity, enabling accurate detection of changes in magnetic field strength. Magnetoresistive sensors are another viable option, utilizing the magnetoresistive effect of magnetic materials to detect magnetic fields and exhibiting high sensitivity. Reed switches consist of a pair of reed contacts that close or open under the influence of a magnetic field, offering a simple and reliable structure. In practical products, the appropriate sensor type can be selected based on requirements such as cost, power consumption, and sensitivity.

[0130] In some embodiments, please refer to Figure 16 The first light-emitting module 15 is configured as a ring-shaped light strip and is fixedly installed on the side wall of the first housing 11.

[0131] In some embodiments, please refer to Figure 19A first driving circuit 200 is provided on the first circuit board 13, which is used to realize the function of magnetic induction triggering light emission. The first driving circuit 200 includes a first transistor N1, a first capacitor C1, a first sensor 14, a first light emission module 15, and a first power supply module 16. The first sensor 14 includes a first terminal 141, a second terminal 142, and a third terminal 143, wherein the first terminal 141 is the positive input terminal of the power supply, the second terminal 142 is the signal output terminal, and the third terminal 143 is the negative ground terminal of the power supply.

[0132] In this design, the first terminal 141 of the first sensor 14 is electrically connected to the positive terminal of the first power module 16, and the third terminal 143 of the first sensor 14 is electrically connected to the negative terminal of the first power module 16, thereby providing a stable operating voltage for the sensor. The second terminal 142 of the first sensor 14 is electrically connected to the base of the first transistor N1, the emitter of the first transistor N1 is electrically connected to the negative terminal of the first power module 16, the collector of the first transistor N1 is electrically connected to the cathode of the first light-emitting module 15, and the anode of the first light-emitting module 15 is electrically connected to the positive terminal of the first power module 16. The first capacitor C1 is connected in parallel between the positive and negative terminals of the first power module 16, i.e., across the power supply terminals, serving to filter and stabilize the voltage, ensuring a clean power supply for the Hall sensor and reducing the impact of voltage fluctuations on detection accuracy.

[0133] In some embodiments, the first driving circuit 200 further includes a first resistor R1. The first terminal 141 of the first sensor 14 is electrically connected to the positive terminal of the first power module 16 through the first resistor R1. The first resistor R1 is used to limit the current flowing into the sensor and can cooperate with the first capacitor C1 to form an RC filter circuit to further stabilize the operating voltage of the sensor.

[0134] In some embodiments, the first driving circuit 200 further includes a second resistor R2, and the second terminal 142 of the first sensor 14 is electrically connected to the base of the first transistor N1 through the second resistor R2. The second resistor R2 is used to limit the base current and protect the transistor.

[0135] In some embodiments, the first sensor 14 is a switch-type Hall sensor with three pins; the first light-emitting module 15 is a light-emitting diode; and the first transistor N1 is an NPN transistor used as an electronic switch.

[0136] The circuit works as follows: When no magnet is nearby, the second terminal 142 of the first sensor 14 outputs a low-level signal. This low-level signal is applied to the base of the first transistor N1 through the base resistor, preventing the transistor N1 from conducting. Therefore, the first transistor N1 is in the off state, and no current flows through the branch containing the first light-emitting module 15, so the light-emitting module does not emit light. When a magnetic component approaches the first block 10, the first sensor 14 detects a change in the magnetic field, and its second terminal 142 outputs a high-level signal. This high-level signal provides sufficient current to the base of the first transistor N1 through the base resistor, causing the first transistor N1 to saturate and conduct. At this time, current flows out from the positive terminal of the first power module 16, through the collector-emitter loop of the first light-emitting module 15 and the first transistor N1, and back to the negative terminal of the power supply, forming a circuit, and the first light-emitting module 15 is lit. When the magnetic component moves away, the output of the first sensor 14 returns to a low level, the first transistor N1 is cut off, and the first light-emitting module 15 is turned off.

[0137] In some embodiments, the first driving circuit 200 may further include a first diode D1, which may be connected in parallel between the positive and negative terminals of the first power module 16, which helps to reduce the probability of damage to circuit components.

[0138] In some embodiments, the first diode D1 is a Zener diode, whose main function in the circuit is to provide overvoltage protection and voltage clamping for the entire circuit.

[0139] In some embodiments, the first capacitor C1 may be an electrolytic capacitor or a ceramic capacitor, and its capacitance value is determined according to the power supply stability requirements.

[0140] In some embodiments, please refer to Figure 20 Some embodiments of this application also provide a magnetic building block toy 1000, which includes a light-emitting control module 300 and at least one set of magnetic building blocks 100 that can cooperate with each other. The light-emitting control module 300 is provided with a control circuit board and a magnetic module (not shown in the figure).

[0141] Each set of magnetic building blocks 100 includes a first building block 10 and a second building block 20. The first building block 10 includes a first housing 11 and at least one first magnet 12, a first circuit board 13, a first sensor 14, a first light-emitting module 15, and a first power module 16 disposed within the first housing 11. The first magnet 12 is positioned within a first limiting region 111 of the first housing 11 to provide magnetic attraction. The first sensor 14 is electrically connected to the first circuit board 13 to sense an external magnetic field. The first light-emitting module 15 is electrically connected to the first circuit board 13 to emit light upon receiving a trigger signal. The first power module 16 is electrically connected to the first circuit board 13, the first sensor 14, and the first light-emitting module 15 to supply power to them.

[0142] The second building block 20 includes a second housing 21 and at least one second magnet 22, a second circuit board 23, a second sensor 24, a second light-emitting module 25, and a second power module 26 disposed within the second housing 21. The second magnet 22 is positioned within a second limiting region 211 of the second housing 21 to provide magnetic attraction. The second sensor 24 is electrically connected to the second circuit board 23 to sense an external magnetic field. The second light-emitting module 25 is electrically connected to the second circuit board 23 to emit light upon receiving a trigger signal. The second power module 26 is electrically connected to the second circuit board 23, the second sensor 24, and the second light-emitting module 25 to supply power to these components.

[0143] The first sensor 14 is configured to sense a magnetic signal generated by the magnetic module when the first building block 10 approaches the light-emitting control module 300, and output a first trigger signal to the first circuit board 13 when the magnetic signal meets a preset trigger condition, so that the first circuit board 13 controls the first light-emitting module 15 to emit light. The second sensor 24 is configured to sense a magnetic signal generated by the magnetic module when the second building block 20 approaches the light-emitting control module 300, and output a second trigger signal to the second circuit board 23 when the magnetic signal meets a preset trigger condition, so that the second circuit board 23 controls the second light-emitting module 25 to emit light.

[0144] In summary, this application, through innovative non-contact magnetic induction triggering technology, not only solves a series of problems associated with traditional illuminated building blocks, such as complex structure, inconvenient assembly, poor waterproofing, and unfriendly triggering, but also creates a completely new proximity-triggered interactive experience, greatly enhancing the product's fun and playability. The flexible sensor and light-emitting module layout allows for a high degree of design freedom, adapting to various functional needs and aesthetic requirements.
