Description

Technical Field

[0001] This utility model relates to the field of electronic circuit teaching toys, and in particular to a magnetic lamp circuit module and circuit toy set. Background Technology

[0002] Current circuit experiment toys improve assembly convenience through standardized modular base designs. A typical structure includes a power module, an adjustment module, and an output module with electrode sockets, such as an LED light. These modules are connected by physical wires to achieve circuit conduction. While this design solves the problem of modular assembly, its function is limited to a binary state of "light on when powered, off when powered," failing to demonstrate the physical process of energy transfer. Especially for the fundamental physical principle of electromagnetic induction, traditional light-emitting modules neither provide a non-contact power supply demonstration nor establish a dynamic relationship between distance and light intensity, making it difficult for children to intuitively understand the magnetic field coupling mechanism.

[0003] Further analysis reveals significant limitations in the educational depth of existing circuit toys: when children operate the LED modules, they can only verify the circuit's on / off state, but cannot observe the continuous physical phenomena of distance change, magnetic field attenuation, and brightness response. This static interactive mode obscures the core principle of electromagnetic induction—the dynamic characteristic that the rate of change of magnetic flux determines the intensity of the induced current in Faraday's law—and misses the opportunity to transform abstract theory into tangible experiments. Although modular design reduces the difficulty of mechanical assembly, the outdated energy transmission method still hinders its educational interpretation of modern wireless power supply technology.

[0004] To address the aforementioned shortcomings, a novel circuit module is urgently needed: one that retains the advantages of modular design while reconstructing the interactive experience through contactless energy transfer. Ideally, the light-emitting component should gradually increase in brightness as it approaches the power supply base and decrease as it moves away, allowing children to intuitively perceive the relationship between the spatial distribution of the magnetic field and the intensity of electromagnetic induction during movement and manipulation. This expands the educational dimension of circuit toys from wire connections to energy transfer. This requires not only overcoming technical challenges such as high-frequency energy conversion and micro-coil integration, but also ensuring a linear mapping between the gradual light effect and distance changes, aligning with the fundamental logic of cognitive education. Existing technologies urgently need improvement to address these issues. Summary of the Invention

[0005] To address the aforementioned issues, the present invention aims to provide a magnetic lamp circuit module and circuit toy kit, which can intuitively demonstrate the non-contact energy transfer process, achieve brightness response of the light-emitting component as distance changes through electromagnetic induction, and enhance children's understanding of magnetic field coupling mechanisms.

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

[0007] This application provides a magnetic lamp circuit module, the technical solution of which is as follows: a base, on the side of which is provided a power interface for plugging in an external power cord, and inside the base is a transmitting coil electrically connected to the power interface; a light-emitting component, including a light-transmitting shell, a receiving coil disposed inside the light-transmitting shell, and a light source electrically connected to the receiving coil; wherein, the light-emitting component is detachably placed on the base; when the light-emitting component is placed on the base, the receiving coil is located within the range of action of the changing magnetic field generated by the transmitting coil, and an induced current is generated in the receiving coil through electromagnetic induction, driving the light source to emit light.

[0008] Furthermore, this application also proposes that an integrated circuit module is provided inside the base, which is connected between the power interface and the transmitting coil to convert the input DC power into AC power to drive the transmitting coil to generate a changing magnetic field.

[0009] Furthermore, this application also proposes that a support cover is installed on the base, and an annular mounting opening is constructed inside the support cover, in which the transmitting coil is fixedly installed; the lower end of the light-emitting component is detachably installed on the annular mounting opening.

[0010] Furthermore, this application also proposes that the support cover is a frustoconical structure with a large lower port diameter and a small upper port diameter, with an annular mounting port located at the upper end of the support cover, and the lower annular port of the support cover being detachably mounted on the base surface.

[0011] Furthermore, this application also proposes that a coupling base post is provided protruding from the bottom of the light-transmitting housing, and the receiving coil is built into the coupling base post; when the light-emitting component is installed in the annular mounting port, the coupling base post extends into the interior of the annular mounting port.

[0012] Furthermore, this application also proposes that the light-transmitting housing includes a detachably connected upper housing and a lower housing, with the coupling base integrally formed on the lower housing.

[0013] Furthermore, this application also proposes that the receiving coil is integrated into a receiving circuit board, which is snapped onto the inner wall of the coupling base pillar of the lower housing; the receiving circuit board includes:

[0014] • The planar receiver coil forms a closed loop through PCB traces;

[0015] • The rectifier and voltage regulator circuit is electrically connected to the receiving coil;

[0016] • The light source is soldered to the surface of the circuit board and connected to the rectifier and voltage regulator circuit.

[0017] Furthermore, this application also proposes that a coil cover is provided inside the base, the coil cover including a base and a cover, with the transmitting coil sandwiched between the base and the cover.

[0018] Furthermore, this application also proposes that the bottom surface of the base is provided with a standardized mating structure, which is a connecting column or a connecting groove for insertion onto the building block board.

[0019] Furthermore, this application also proposes a circuit toy set, including a building board and the aforementioned magnetic lamp circuit module; the surface of the building board has standardized interlocking structures distributed in a matrix, and the base of the magnetic lamp circuit module is detachably connected to the standardized interlocking structures of the building board through its standardized interlocking structures.

[0020] As can be seen from the above, the magnetic lamp circuit module and circuit toy kit provided in this application generate a changing magnetic field through the transmitting coil of the base, and the light-emitting component generates an induced current within the magnetic field range through the receiving coil to drive the light source to emit light, realizing non-contact energy transfer and distance-response brightness change. It has the advantages of intuitively demonstrating the principle of electromagnetic induction and improving children's understanding of the magnetic field coupling mechanism.

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise", 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 utility model 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 utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In existing technologies, circuit experiment toys achieve block-like assembly through modular design, but the energy transfer method is limited to physical wire connections. Traditional modules only show a light-on-off state when powered on, failing to demonstrate the relationship between magnetic field changes and induced current during electromagnetic induction. When children operate such toys, they can only verify the circuit's on / off result, making it difficult for them to understand the physical laws of non-contact energy transfer.

[0032] To address the aforementioned issues and the limitation of existing toys in dynamically demonstrating magnetic field coupling mechanisms, a proposal was made to construct a contactless energy transmission system. Analysis revealed the need to establish magnetic coupling between the power supply module and the light-emitting component. This involves driving an induced current through changes in the spatial magnetic field. Ultimately, an electromagnetic induction structure with transmitting and receiving coils was chosen, utilizing an alternating magnetic field to achieve wireless energy transfer, allowing the light source brightness to dynamically change with the component's position.

[0033] Example 1:

[0034] like Figure 1-5 As shown, this embodiment relates to a magnetic lamp circuit module, which includes a base 1.

[0035] The base 1 has a standardized mating structure 16 on its bottom surface. This standardized mating structure 16 is a connecting post or a connecting groove for insertion into the building block board. The standardized mating structure 16 refers to a mechanical connection component with uniform dimensions, specifically implemented as a cylindrical protrusion or recess. This structure achieves positioning and fixation between modules through predetermined geometric matching. Its function is to eliminate connection differences between different modules, ensuring rapid adaptation between the magnetic lamp module and the building block board. Specifically, the geometric dimensions of the standardized mating structure 16 are completely consistent with the matrix-like interfaces distributed on the surface of the building block board, allowing the bottom surface of the base 1 to be directly aligned with any connection point of the building block board for insertion. When the connecting post is inserted into the groove of the building block board, the chamfered design of the post's sidewall guides the contact surface to automatically correct positional deviations, ensuring a stable connection between the base 1 and the building block board.

[0036] Furthermore, the base 1 has a power interface 11 for connecting an external power cord on its side, and a transmitting coil 12 electrically connected to the power interface 11 is provided inside the base 1; the light-emitting component 2 includes a light-transmitting housing 21, a receiving coil disposed inside the light-transmitting housing 21, and a light source 23 electrically connected to the receiving coil; wherein, the light-emitting component 2 is detachably placed on the base 1; when the light-emitting component 2 is placed on the base 1, the receiving coil is located within the range of the changing magnetic field generated by the transmitting coil 12, and an induced current is generated in the receiving coil through electromagnetic induction, driving the light source 23 to emit light.

[0037] The base 1 is a supporting structure that carries the power supply components. It can be implemented using an injection-molded plastic shell, with an internal cavity to house the coils and circuitry. The power interface 11 is the physical port for connecting to an external power source, used to input DC power into the power supply system. The transmitting coil 12 is a conductive element that generates an alternating magnetic field. It can be made of enameled copper wire wound into a ring structure, generating a changing magnetic field through high-frequency alternating current. The light-transmitting shell 21 is a transparent or semi-transparent shell that encloses the light source 23. It can be made of polycarbonate material through injection molding to achieve uniform light diffusion. The receiving coil is a conductive element that obtains electrical energy through electromagnetic induction. It can be a PCB-printed coil or a wound coil, forming a closed loop with the light source 23. The detachable placement refers to a structural design where there is no fixed connection between components. This can be achieved through magnetic positioning, gravity positioning, or other positioning methods, allowing the user to freely move the light-emitting component 2.

[0038] An external power source supplies electrical energy to the base 1 through the power interface 11, and the transmitting coil 12 generates a high-frequency alternating magnetic field inside the base 1. When the light-emitting component 2 is placed on the surface of the base 1, the receiving coil is within the effective range of the magnetic field and generates an induced electromotive force by cutting magnetic field lines. This electromotive force drives the light source 23 to emit light, and the intensity of the induced current is related to the relative position of the two coils. The light-transmitting shell 21 visualizes the brightness change of the light source 23. Furthermore, by adjusting the distance between the light-emitting component 2 and the base 1, the user can observe the phenomenon that the brightness decreases as the distance increases. The magnetic coupling between the transmitting coil 12 and the receiving coil does not require physical contact, making the energy transfer process a direct demonstration of the electromagnetic induction principle. Through the above technical solution, this application realizes a dynamic visualization demonstration of the electromagnetic induction phenomenon. Children can directly observe the relationship between brightness and distance by moving the light-emitting component 2 and understand the influence of the spatial distribution of the magnetic field on the intensity of the induced current. The wireless energy transmission structure breaks through the interactive mode of traditional circuit toys, expanding the teaching of electromagnetism from static circuits to dynamic field energy transfer, effectively improving the effect of science education.

[0039] In a further embodiment, an integrated circuit module 14 is installed inside the base 1. This module is connected between the power interface 11 and the transmitting coil 12, converting the input DC power into AC power to drive the transmitting coil 12 to generate a changing magnetic field. The integrated circuit module 14 refers to the circuit component inside the base 1 used to convert electrical energy into its form. Specifically, it can be implemented using an H-bridge inverter circuit or an oscillator circuit to convert the input DC power into high-frequency AC power. This module actively controls the current direction and frequency to ensure that the transmitting coil 12 generates a periodically changing magnetic field. Here, AC power refers to electrical energy in which the current direction changes periodically with time. By changing the current direction and frequency, the magnetic field strength of the transmitting coil 12 exhibits a regular change.

[0040] Specifically, the integrated circuit module 14, as the core of energy conversion, receives DC input from the power interface 11 and performs an inverter function through its internal circuit topology. When the DC power is alternately switched on and off by the switching elements, an alternating current is generated and output to the transmitting coil 12. The transmitting coil 12 forms a time-varying magnetic field under the drive of the alternating current, which penetrates the surface of the base 1 and acts on the external space. By controlling the frequency and amplitude of the alternating current, the rate and intensity of the magnetic field change can be adjusted, thereby establishing the basic conditions required for electromagnetic induction. This solution, by introducing the integrated circuit module 14, converts static DC power into a dynamic alternating electromagnetic field, enabling the light-emitting component to obtain energy through spatial magnetic field coupling without physical contact, breaking through the limitations of traditional toys that rely on wire connections. Through the above technical solution, this application realizes wireless energy transmission based on electromagnetic induction, allowing the light-emitting component 2 to work continuously without physical wire connections. When the light-emitting component 2 is close to the base 1, the receiving coil generates an induced current in the alternating magnetic field, driving the light source 23 to emit light. This design enables children to directly observe non-contact power supply phenomena and perceive the dynamic law of magnetic field strength changing with distance through the active generation of alternating magnetic fields, thus intuitively understanding the principle of electromagnetic induction.

[0041] like Figure 1As shown in Figures 3 and 4, a support cover 15 is installed on the base 1. An annular mounting opening 13 is constructed within the support cover 15. The transmitting coil 12 is fixedly installed within the annular mounting opening 13, and the lower end of the light-emitting component 2 is detachably installed on the annular mounting opening 13. The support cover 15 is a hollow cover installed on the surface of the base 1, which can be injection molded from plastic material, with an annular recessed structure on its inner side to accommodate the transmitting coil 12. This structure ensures a concentrated magnetic field coverage area and reduces energy loss by limiting the installation position of the transmitting coil 12. The annular mounting opening 13 is a circular opening formed at the top of the support cover 15, which can be formed by molding an annular groove with an inner diameter matching the outer diameter of the bottom of the light-emitting component 2. This design provides a circumferential positioning reference for the light-emitting component 2, preventing magnetic circuit misalignment caused by installation offset. Detachable installation means that the light-emitting component 2 is connected to the annular mounting opening 13 by plugging or snapping, or directly mounted on the annular mounting opening 13. This method ensures positional accuracy while retaining the freedom of modular assembly. In this design, the support cover 15 confines the transmitting coil 12 within a preset space via the annular mounting port 13, ensuring a uniform distribution of the magnetic field generated by the coil in the vertical direction. When the lower end of the light-emitting component 2 is inserted into the annular mounting port 13, the receiving coil inside automatically enters the effective magnetic field area, achieving maximum magnetic flux coverage. The insertion and engagement of the light-emitting component 2 with the annular mounting port 13 ensures, through mechanical constraints, that the receiving coil and the transmitting coil 12 remain axially aligned after each assembly and disassembly, maintaining a stable magnetic coupling efficiency. Through this technical solution, this application solves the problem of low magnetic field coupling efficiency caused by alignment deviation in non-contact energy transfer. The annular mounting port 13 of the support cover 15 provides a fixed mounting space for the transmitting coil 12, ensuring a controllable magnetic field distribution. The detachable connection design between the light-emitting component 2 and the annular mounting port 13 ensures, through a mechanical limiting mechanism, that the receiving coil is always in the optimal sensing position. This structure maintains the modular assembly and disassembly characteristics while allowing children to naturally achieve precise coil alignment during assembly, observing a stable light-emitting effect without additional adjustments.

[0042] Furthermore, the support cover 15 has a frustum-shaped structure with a large lower diameter and a small upper diameter. An annular mounting port 13 is located at the upper end of the support cover 15, and the lower annular opening of the support cover 15 is detachably mounted on the surface of the base 1. The frustum-shaped structure refers to the support cover 15 having a gradually decreasing cross-section. This can be achieved using plastic injection molding. The large-diameter bottom end fits against the surface of the base 1, while the small-diameter top end forms the annular mounting port 13. The conical transition enhances the anti-overturning capability of the support cover 15. The detachable mounting method means that the lower annular opening of the support cover 15 is fixed to the surface of the base 1 via a sleeve, snap-fit, or threaded connection, facilitating quick disassembly and maintenance of the internal coil assembly. The large-diameter bottom of the frustoconical support cover 15 forms a stable connection with the surface of the base 1. The increased contact area effectively disperses the external force and prevents the support cover 15 from shifting in the horizontal direction. The conical sidewall serves as a guide structure, guiding the bottom of the light-emitting component 2 to move along a predetermined path during the installation process, and finally accurately inserting it into the top annular mounting port 13, ensuring that the receiving coil and the transmitting coil 12 are axially aligned.

[0043] like Figure 2 and 3 As shown in Figure 5, a coupling base post 24 protrudes from the bottom of the light-transmitting housing 21, and the receiving coil is built into the coupling base post 24. When the light-emitting component 2 is installed in the annular mounting port 13, the coupling base post 24 extends into the annular mounting port 13. The coupling base post 24 refers to the columnar structure formed by extending outward from the bottom of the light-transmitting housing 21. Specifically, it can be made by integral injection molding of transparent plastic of the same material as the light-transmitting housing 21. It has an internal cavity to accommodate the receiving coil, and the coil is kept in a fixed position by wrapping it with a rigid material. This structure achieves coil positioning while avoiding the risk of exposure. Specifically, the extension length of the coupling base post 24 is configured such that when it is fully inserted into the annular mounting port 13, the receiving coil and the transmitting coil 12 form a complete vertical overlap. During the placement of the light-emitting component 2, the outer wall of the coupling base post 24 does not contact the inner wall of the annular mounting port 13, only limiting its range of motion. Alternatively, the contact between the outer wall of the coupling base 24 and the inner wall of the annular mounting port 13 creates a sliding guiding effect, forcing the receiving coil to move along a preset path directly above the transmitting coil 12. At this time, the wrapping constraint of the annular mounting port 13's sidewall on the coupling base 24 compensates for lateral positional deviations caused by manual operation, ensuring that the axial deviation of the two coils does not exceed the allowable range. This structural combination keeps the geometric parameters of the magnetic field energy transmission path constant, thereby maintaining the stability of the induced current.

[0044] Furthermore, the light-transmitting housing 21 includes a detachably connected upper housing 211 and a lower housing 212, with the coupling base 24 integrally formed on the lower housing 212. The detachable connection refers to the physical separation of the two housing parts through snap-fit, threaded, or magnetic means. Specifically, it can be achieved by using a snap-fit ​​protrusion and groove, allowing the upper housing 211 and lower housing 212 to disengage under external force. This feature allows for disassembly of the housing without compromising its integrity, facilitating direct access to internal components. The integral forming means that the coupling base 24 and lower housing 212 are formed from the same material using injection molding to create a single solid structure. This feature creates a rigid connection between the coupling base 24 and lower housing 212 without relative displacement, avoiding positional deviations caused by repeated disassembly and reassembly. When it is necessary to replace the light source 23 or repair the receiver coil, the internal circuit board and light source 23 assembly can be directly exposed by separating the connection structure between the upper housing 211 and lower housing 212, without cutting or damaging the light-transmitting housing 21. The integrated manufacturing process of the coupling base 24 and the lower housing 212 ensures that they remain in a fixed position during repeated disassembly and assembly, preventing misalignment between the receiving coil and the transmitting coil 12 due to loosening of the base, and maintaining the stability of electromagnetic induction efficiency. Through the above technical solution, this application achieves rapid inspection and replacement of the internal components of the light-transmitting housing 21. The housing can be disassembled and reassembled without special tools, reducing maintenance complexity. The rigid connection structure between the coupling base 24 and the lower housing 212 ensures that the receiving coil can still be accurately aligned with the transmitting coil 12 after repeated disassembly and assembly, maintaining the stability of electromagnetic energy transmission efficiency.

[0045] like Figure 2As shown, the receiving coil of the magnetic lamp circuit module is integrated into the receiving circuit board 210, which is snapped onto the inner wall of the coupling base post 24 of the lower housing 212. The receiving circuit board 210 includes a planar receiving coil, a rectifier and voltage regulator circuit, and a light source 23 soldered to the surface of the circuit board. The planar receiving coil forms a closed loop through PCB traces. The rectifier and voltage regulator circuit is electrically connected to the receiving coil, and the light source 23 is connected to the rectifier and voltage regulator circuit. The planar receiving coil refers to a planar spiral structure formed by PCB traces, which can be achieved through double-sided copper etching. The geometric parameters of its closed loop can be adjusted according to the magnetic field coupling efficiency requirements. This design integrates the coil and the circuit board, solving the problems of large space occupation and easy misalignment of traditional wound coils. The rectifier and voltage regulator circuit is a power conversion module including a bridge rectifier and a filter capacitor. It can be implemented by combining surface-mount rectifier diodes and ceramic capacitors to convert alternating induced current into DC output. This circuit is directly laid out on the receiving circuit board 210, shortening the current transmission path and reducing energy loss. Soldering of light source 23 refers to connecting the LED chip pins to the circuit board pads using a reflow soldering process. This can be achieved using SMT (Surface Mount Technology) to eliminate contact resistance caused by wire insertion. This process creates a rigid connection between light source 23 and the circuit board, improving its resistance to mechanical shock.

[0046] The receiver circuit board 210 is embedded inside the coupling base 24 of the lower housing 212 via a snap-fit ​​structure. The planar receiver coil forms a closed loop between PCB layers, which can efficiently capture changes in the transmitter's magnetic field and induce alternating current. After being converted into direct current by a rectifier and voltage regulator circuit, the current directly drives the light source 23 soldered on the surface of the circuit board to emit light. The trace width and spacing of the planar coil are optimized to achieve maximum inductance within a limited area. At the same time, the onboard layout of the rectifier circuit and the light source 23 minimizes the power transmission path. The snap-fit ​​structure on the inner wall of the coupling base 24 constrains the displacement of the circuit board through a limiting surface, ensuring that the planar coil and the transmitter coil 12 remain parallel and aligned, avoiding a decrease in magnetic coupling efficiency due to angular deviation. Through the above technical solution, this application achieves a high degree of integration between the receiver coil and the power conversion circuit, significantly reducing the size of the wireless power receiving module. At the same time, the snap-fit ​​fixing method enhances the structural stability of the light-emitting component 2 during movement. The integrated design of the rectifier circuit and the light source 23 on the board ensures the efficient conversion of induced current into light energy, allowing children to observe the continuous response of brightness change with distance when moving the light-emitting component 2, and intuitively understand the relationship between magnetic field strength and induced current in the principle of electromagnetic induction.

[0047] like Figure 2 and 4As shown, a coil cover 17 is provided inside the base 1. The coil cover 17 includes a base 171 and a cover 172, with the transmitting coil 12 sandwiched between the base 171 and the cover 172. The coil cover 17 is a rigid shell structure that surrounds the transmitting coil 12, and can be made of injection-molded plastic. Its function is to limit the physical displacement of the coil and isolate external mechanical vibration. The base 171 is a support component connected to the inner wall of the base 1, and can be made of injection-molded material with positioning bosses. Its function is to provide a planar support reference for the coil. The cover 172 is a closed component that covers the base 171, and can be made of injection-molded material that matches the shape of the base 171. Its function is to apply vertical pressure to the coil. The clamping refers to the fixing method of placing the coil between the base 171 and the cover 172, and its function is to maintain the planar position stability of the coil through bidirectional constraint. Specifically, the transmitting coil 12 is clamped between the base 171 and the cover 172 of the coil cover 17. The base 171 is fixed inside the base 1 by a positioning boss, and the cover 172 and the base 171 form a closed structure by a snap-fit. When an external power source is input, the transmitting coil 12 remains flat on the plane of the base 171, and the cover 172 presses the coil edge tightly with a rigid contact surface to prevent the coil from deforming or shifting under external force. The enclosed space formed by the base 171 and the cover 172 prevents direct collisions of external objects with the coil, while the rigid material shell reduces the influence of external vibrations on the coil position, ensuring that the transmitting coil 12 is always at the preset geometric center position inside the base 1, maintaining the spatial distribution stability of the magnetic field it generates.

[0048] Example 2:

[0049] This embodiment relates to a circuit toy set, including a building block board and a magnetic lamp circuit module described in Embodiment 1. The surface of the building block board has standardized interlocking structures distributed in a matrix. The base of the magnetic lamp circuit module is detachably connected to the standardized interlocking structures of the building block board through its standardized interlocking structures. The building block board refers to an assembly substrate with regularly arranged connection nodes on its surface. Specifically, it can be made into a plastic board with raised or recessed interlocking structures using injection molding technology, providing an expandable mounting surface for the magnetic lamp module. Through the above technical solution, this application enables children to intuitively perceive the physical law of magnetic field strength changing with spatial distance in non-contact energy transmission by moving the magnetic lamp module on the building block board. The matrix interlocking structure of the building block board provides quantifiable operation nodes for module position adjustment, creating a synergistic effect between the teaching of electromagnetic induction principles and the modular spatial layout, solving the problem that traditional circuit toys cannot reveal the magnetic field coupling mechanism through dynamic light effect feedback.
