Description

Technical Field

[0001] This application relates to the field of toy technology, specifically to a magnetically triggered building block toy assembly. Background Technology

[0002] Building blocks, with their flexibility and creativity in assembly, have become popular educational toys for users of all ages. The assembly methods of existing building blocks are constantly being enriched, with interlocking and magnetic assembly methods being widely used. However, their functions are still mostly focused on the structural assembly level, and they generally do not have the function of lighting up, making it difficult to meet users' diverse needs for visual effects and scene creation of building blocks.

[0003] To compensate for the aforementioned shortcomings, some improved building block toys have attempted to add lighting functions. However, the light control switches for these blocks are mostly externally designed, with the switch structure protruding from the surface of the block itself. This design, on the one hand, creates physical interference when the blocks are joined, disrupting the fit and smoothness of assembly, affecting normal building operations, and even limiting the diversity of possible building shapes. On the other hand, the external switch structure disrupts the overall design of the block itself, making the block appear obtrusive and detracting from its overall aesthetic appeal, contradicting the original design intent of building block toys.

[0004] Meanwhile, external switches are susceptible to damage from impacts and wear, which not only reduces their lifespan but also increases the probability of malfunction in building block toys. Furthermore, the external electrical structure poses certain safety hazards. Therefore, how to achieve the lighting function of building block toys while avoiding the adverse effects of external switches on the building block assembly and appearance has become a pressing technical problem to be solved in the building block toy industry.

[0005] Furthermore, the switching method lacks originality, failing to stimulate users' desire to explore and their interest in operation, and thus failing to bring users a novel and unique gaming experience.

[0006] In view of the above, this application is hereby submitted. Utility Model Content

Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0053] In the description of this application, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0054] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" 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; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0055] See Figures 1 to 9As shown in the illustration, this application provides a magnetically triggered building block toy assembly, including a first building block assembly 1 and a second building block assembly 2. The first building block assembly includes several blocks, each block comprising a light-transmitting shell 11, a battery 12, a circuit board 13, a magnetic sensor 14, and LED beads 15. The light-transmitting shell 11 has a cavity, within which the battery 12, circuit board 13, magnetic sensor 14, and LED beads 15 are all disposed. The battery 12, magnetic sensor 14, and LED beads 15 are all electrically connected to the circuit board 13. The second building block assembly 2 can be assembled into a rod-shaped body, with at least one magnetic element 21 provided at the end of the rod-shaped body. The magnetically triggered building block toy assembly is configured such that when one end of the second building block assembly 2 approaches the blocks, it triggers the magnetic sensor 14, causing the circuit board 13 to control the LED beads 15 to light up / turn off / flicker.

[0056] The magnetic triggering building block toy component provided in this application adopts a non-contact control method triggered by magnetic force. The magnetic sensor 14 is triggered when the magnetic component 21 at the end of the second building block component 2 is brought close to the block, realizing precise control of the circuit board 13 to turn on / off / blink the LED 15. This triggering method is integrated with the building block assembly action. Without the need for an additional manual switch, all electrical components that realize the functions of light emission and control, such as the battery 12, circuit board 13, magnetic sensor 14, and LED 15, can be built into the light-transmitting shell 11 cavity of the first building block component 1. There is no external switch structure, which fundamentally eliminates the physical interference caused by external switches to the building block assembly. This ensures the fit and smooth operation during the building block assembly process, does not limit the diversity of building block assembly shapes, and maintains the overall shape integrity of the building block body. This makes the building block appearance simple and harmonious, and completely solves the problem of external switches destroying the aesthetics of the building blocks. Furthermore, there is no need for additional manual switching operations, and the control process is convenient and natural, making the use of the light-up function of the building blocks more closely integrated with the building experience, thus enhancing the fun and ease of operation of the toy.

[0057] Furthermore, the second building block component 2 can be assembled into a rod-shaped body. Its modular design gives it flexible assembly characteristics. Its cooperation with the first building block component 1 is achieved only through magnetic triggering via the end magnetic component 21. This design ensures that the second building block component 2 will not interfere with the light-emitting control of the first building block component 1 during assembly. Even if the first building block component 1 is connected to other building blocks, it will not affect the second building block component 2's control of the LED bead 15 switch inside the first building block component 1. The two are independent yet closely cooperate, without changing the assembly logic of the building blocks themselves. This ensures the realization of the light-emitting triggering function while also taking into account the original assembly flexibility and creativity of the building block toy. It allows the building block toy to retain its core educational assembly value while adding a light-emitting function.

[0058] The light-transmitting outer shell 11 provides a carrier for the light from the internal LED beads 15 to pass through, and also provides effective protection for all built-in electrical components, achieving a unity of protection, light transmission and structural integrity. In addition, the electrical connection design between each component and the circuit board 13 makes the internal structure of the first building block assembly 1 compact and reasonable, suitable for the small product form of building block toys, and has good product practicality and industrialization prospects.

[0059] In some possible implementations, the LED 15, battery 12, and magnetic sensor 14 are all fixed to the circuit board 13 to form a single unit, which is housed within the cavity. This design integrates the LED 15, battery 12, and magnetic sensor 14 onto the circuit board 13, simplifying the internal structure and facilitating assembly and maintenance. Furthermore, the single unit housed within the cavity enhances the compactness and stability of the structure, ensuring that the components do not shift due to shaking during use and guaranteeing reliable operation of the light-emitting control function. Moreover, the single-unit design also helps improve production efficiency, reduce production costs, and enhance the product's market competitiveness.

[0060] In some possible implementations, the circuit board 13 is a circular plate. The LED beads 15 and the magnetic sensor 14 are located on one side of the circuit board 13 along its thickness direction, and the battery 12 is located on the other side of the circuit board 13 along its thickness direction. The battery 12 is connected to the circuit board 13 via a conductive sheet. Designing the circuit board 13 as a circular plate and rationally arranging the positions of the LED beads 15, magnetic sensor 14, and battery 12 makes full use of the space of the circuit board 13, resulting in a more compact overall structure. The LED beads 15 and magnetic sensor 14 are located on the same side of the circuit board 13, facilitating signal transmission and collaborative operation between them. The battery 12 is located on the other side and connected via a conductive sheet, ensuring the stability of the circuit connection and making the installation and replacement of the battery 12 more convenient. This layout not only improves the utilization rate of the internal space of the modular assembly but also helps to improve the response speed and accuracy of the light-emitting control function.

[0061] In some possible implementations, the light-transmitting outer shell 11 includes a first shell portion 111 and a second shell portion 112. The first shell portion 111 and the second shell portion 112 are interlocked, forming the cavity between them. A slot is provided on the side of the first shell portion 111 opposite to the second shell portion 112, and a post is provided on the side of the second shell portion 112 opposite to the first shell portion 111. The post of one of two connected first building block components is inserted into the slot of the other. The interlocking design of the first shell portion 111 and the second shell portion 112 in the light-transmitting outer shell 11 facilitates the installation and replacement of internal electrical components and also provides convenience for manufacturing. The slot on the first shell portion 111 and the post on the second shell portion 112 allow for easy assembly and combination of multiple first building block components, increasing the playability and stability of the building block toy. This assembly method not only conforms to the basic characteristics of building block toys but can also be combined with magnetic triggering light-emitting function to bring a richer experience to players. Moreover, this structural design ensures the overall strength and stability of the building blocks while also taking into account the simplicity and aesthetics of the appearance, further enhancing the quality and appeal of the product.

[0062] In some possible implementations, the first shell portion 111 includes a first bottom wall 1112 and a first peripheral side wall 1113. A plurality of limiting ribs 1114 are provided on the first bottom wall 1112, and the limiting ribs 1114 are arranged sequentially at intervals along the circumference of the first bottom wall 1112. The limiting ribs 1114 enclose a limiting area 1115, and the integral part is limited within the limiting area 1115.

[0063] A limiting rib 1114 is provided on the first bottom wall 1112 to form a limiting area 1115, which can effectively position and fix the whole component, prevent the whole component from moving randomly in the cavity, ensure the stable and reliable connection between various electrical components, and thus guarantee the normal operation of magnetic triggering and light-emitting control functions. This limiting design is simple and ingenious, requiring no additional complex fixing structure, saving space and reducing manufacturing costs. At the same time, the setting of the limiting rib 1114 can also play a certain role in buffering and protection, reducing the vibration and impact on the whole component during the use of the building blocks, and extending the service life of the product.

[0064] In some possible implementations, the second shell portion 112 includes a second bottom wall 1122 and a second circumferential side wall 1123 located around the second bottom wall 1122, with a notch 1124 formed in the second circumferential side wall 1123. A positioning rib 1111 is provided on the inner wall of the first circumferential side wall 1113, extending circumferentially along the first circumferential side wall 1113. An annular groove 1121 is provided on the outer surface of the second circumferential side wall 1123. When the first shell portion 111 and the second shell portion 112 are connected, the second circumferential side wall 1123 is inserted into the inner side of the first circumferential side wall 1113, and the positioning rib 1111 is embedded in the annular groove 1121. The notch 1124 in the second circumferential side wall 1123 of the second shell portion 112 provides a certain elastic deformation space for the engagement of the first shell portion 111 and the second shell portion 112, making the engagement process smoother and also facilitating the opening of the light-transmitting outer shell 11 for inspection or replacement of internal components when needed. The positioning ribs 1111 on the inner wall of the first sidewall 1113 and the annular grooves 1121 on the outer surface of the second sidewall 1123 cooperate with each other to accurately position the relative positions of the first shell 111 and the second shell 112, ensuring the accuracy and tightness of their engagement and preventing loosening or misalignment. This structural design further enhances the overall strength and stability of the light-transmitting shell 11, providing more reliable protection for the internal electrical components and ensuring that the magnetically triggered building block toy assembly can function normally in various usage environments.

[0065] In some possible implementations, the second building block assembly 2 includes multiple cylindrical parts 22 and multiple connecting parts 23. The cylindrical parts 22 are arranged sequentially, and the connecting parts 23 are located between adjacent cylindrical parts 22, with each end inserted into one of the two cylindrical parts 22. At least the end cylindrical parts 22 are provided with magnetic components 21. The multiple cylindrical parts 22 are arranged sequentially and connected by the connecting parts 23 to form a flexibly assembleable rod-shaped structure. This modular design allows the second building block assembly 2 to be freely combined into different lengths and shapes according to the player's needs. The connecting parts 23 adopt a split structure with a central body 231 and two end insert bodies 232. The insert bodies 232 achieve a stable connection with the cylindrical parts 22 through a double insert arm 2321 design. The engagement mechanism of the latching protrusion 2322 and the latching groove 222 ensures the structural strength after assembly, effectively preventing loosening or detachment during assembly. The cylindrical magnetic component 21 built into the end sleeve 22 is installed in an embedded manner, which ensures the magnetic field strength required for magnetic triggering while avoiding interference from exposed magnetic components 21 during assembly. At the same time, the cylindrical shape is highly compatible with the internal structure of the sleeve 22, improving the overall space utilization. This structural design allows the second building block component 2 to maintain assembly flexibility while accurately triggering the magnetic sensor 14 of the first building block component 1, achieving a reliable response for lighting control.

[0066] In some possible implementations, the cylindrical component 22 has a cavity 221, and the connecting component 23 includes a central body 231 and insertable bodies 232 located at both ends of the central body 231. The insertable bodies 232 at both ends of the connecting component 23 are respectively inserted into the cavities 221 of the two cylindrical components 22, and the two cylindrical components 22 cover the central body 231. The structure of the insertable bodies 232 and the cavities 221 cooperating and connecting makes the connection between the connecting component 23 and the cylindrical component 22 more stable and less prone to loosening. This design allows players to operate more smoothly during the assembly process, without worrying about the connection between parts being weak and affecting the assembly effect, further enhancing the assembly experience of the building block toy. Moreover, this structure, while ensuring connection strength, also takes into account the simplicity of the appearance, making the second building block component 2 look more neat and beautiful, meeting the design requirements of building block toys.

[0067] In some possible implementations, the cylindrical member 22 is provided with a locking groove 222 communicating with the cylindrical cavity 221. The locking groove 222 extends circumferentially along the cylindrical member 22. The insertion body 232 includes two spaced-apart insert arms 2321, each with a locking protrusion 2322. When the insertion body 232 is inserted into the cylindrical cavity 221 of the corresponding cylindrical member 22, the locking protrusion 2322 on at least one insert arm 2321 engages with the corresponding locking groove 222. The engaging structure of the locking protrusion 2322 and the locking groove 222 not only enhances the connection stability between the connecting member 23 and the cylindrical member 22, effectively preventing parts from falling off during assembly and play, but also provides a certain positioning and guiding function for the assembly operation. When assembling the blocks, players can more accurately determine the connection position between the connecting part 23 and the cylindrical part 22 by observing the correspondence between the protruding parts 2322 and the slots 222. This makes the assembly process easier and more accurate, reducing the difficulty of assembly, and is especially suitable for younger children. At the same time, this snap-fit ​​structure is simple and ingeniously designed, requiring no additional tools or complicated steps. It ensures ease of assembly without compromising the overall aesthetics of the building block toy, further enhancing the practicality and fun of this magnetically triggered building block toy component.

[0068] In some possible implementations, the magnetic component 21 is a cylinder, embedded within the cavity 221 of the corresponding cylindrical component 22, and located at the end of the cylindrical component 22. Designing the magnetic component 21 as a cylinder and embedding it within the cavity 221 at the end of the cylindrical component 22 fully utilizes the internal space of the cylindrical component 22, forming an integrated structure with the cylindrical component 22. This ensures the stability of the magnetic component 21's installation and avoids potential safety hazards from exposed magnetic components. The cylindrical shape of the magnetic component 21 generates a uniform magnetic field distribution. When the second building block assembly 2 approaches the first building block assembly 1, it ensures that the magnetic sensor 14 stably receives the magnetic field signal, improving trigger sensitivity and reliability. The embedded installation method completely conceals the magnetic component 21 within the cylindrical component 22, maintaining the flatness of the building block surface and the overall aesthetic appeal.
