Description

Technical Field

[0001] The present invention relates to the technical field of magnetic building blocks, and in particular to a luminous magnetic building block. Background Art

[0002] Magnetic building blocks are an innovative educational toy consisting of geometric modules embedded with magnets. They can be spliced at multiple angles through the principle of magnetic attraction and can be freely combined to construct three-dimensional structures.

[0003] Existing magnetic building blocks can often be designed as functional building blocks connected to electrical units (such as LEDs and sound generators), and magnetic splicing is usually used to achieve circuit conduction; for example, when two magnetic building blocks are magnetically spliced together, a positive terminal and a negative terminal are provided at the splicing position between the two building blocks. The positive and negative terminals are in one-to-one contact to form a pathway. After the power supply is connected, the current can pass through this pathway to drive the internal light-emitting or sound-emitting elements. Wires connecting the terminals and elements need to be laid inside the building blocks.

[0004] The wires in the above-mentioned magnetic building blocks are usually fixed by bonding or welding, but the internal space of the building blocks is usually extremely limited and the structure is compact. The wires need to be precisely arranged to connect the key electrical nodes scattered on the splicing surface (terminals) and inside. This makes the wiring structure of the wires complex and the assembly process tedious. It needs to rely on the manual operation of skilled workers, resulting in greater production difficulty and a longer production cycle. Summary of the Invention

[0005] In order to improve the problem of cumbersome installation of internal wires in functional magnetic building blocks, which leads to a long production cycle, this technical solution provides a luminous magnetic building block.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A luminous magnetic building block comprises a building block body, wherein the building block body is provided with magnetic parts along the circumference thereof, and the building block body has a cavity therein, and further comprises:

[0008] a conductive frame assembly, the conductive frame assembly comprising a positive conductive wire frame and a negative conductive wire frame, the positive conductive wire frame and the negative conductive wire frame being stacked and arranged in the cavity without contacting each other;

[0009] an electrical function module installed in the cavity, wherein a positive electrode of the electrical function module is electrically connected to the positive conductive wire frame, and a negative electrode of the electrical function module is electrically connected to the negative conductive wire frame;

[0010] At least one set of electrical connection contacts, comprising a positive terminal disposed on the positive conductive wire frame and a negative terminal disposed on the negative conductive wire frame, wherein the positive terminal and the negative terminal are both located on the same side of the building block body;

[0011] When the two building block bodies are magnetically spliced together by the magnetic member, the positive terminals on both sides contact the negative terminals on both sides on a one-to-one basis at the splicing surface, thereby establishing a conductive path.

[0012] Through the above technical solution, when a luminous magnetic building block is used normally, a three-dimensional conductive network is formed by a stacked conductive frame component built into the cavity, and a gap is left between the two conductive frames to avoid contact and circuit interruption. The positive / negative terminals connected to the positive / negative conductive wire frames respectively extend outward from the electrode frame to the side surface of the building block body; the electric function module is located in the cavity and the positive pole is connected to the positive conductive wire frame and the negative pole is connected to the negative conductive wire frame. When the magnetic building block is connected to the power supply, the current path is along the positive terminal, the positive conductive wire frame, the positive pole of the electric function module, the electric function module, the electric function The negative pole of the module, the negative conductive wire frame, and the negative terminal complete the circuit. When the two building blocks are magnetically spliced together through magnetic parts, the magnetic force drives the positive terminals and negative terminals on both sides of the splicing surface to make precise contact one by one. The current is transmitted to the adjacent building blocks, and a conductive path across the building blocks is automatically established. The splicing of multiple building blocks can trigger functions such as lighting, power supply, or sound, respectively, to achieve an intelligent interactive experience of splicing and powering. This design installs the integrated conductive frame component in the inner cavity to replace the traditional wire part, optimizes the internal wiring, and makes assembly faster, thereby shortening the production cycle.

[0013] Preferably, the conductive frame assembly further includes a boundary frame, which is sandwiched between the positive conductive wire frame and the negative conductive wire frame. The positive conductive wire frame, the boundary frame and the negative conductive wire frame are stacked and fixed in sequence. The positive end of the electrical function module extends and abuts between the positive conductive wire frame and the boundary frame, and the negative end of the electrical function module extends and abuts between the boundary frame and the negative conductive wire frame.

[0014] Through the above technical solution, an insulating dividing frame is added to the conductive frame assembly, and the dividing frame is used to achieve rigid insulation isolation between the positive and negative conductive wire frames, avoiding the risk of short circuit caused by direct contact between the two conductive wire frames, and improving stability. The positive conductive wire frame, dividing frame, and negative conductive wire frame are stacked and fixed in sequence and integrated into the cavity, eliminating the welding process, simplifying the assembly process, and further shortening the production cycle.

[0015] Preferably, the boundary frame is provided with embedding grooves, which include embedding groove 1 and embedding groove 2, wherein the embedding groove 1 is located on one end surface of the boundary frame facing the positive conductive wire frame, and the embedding groove 2 is located on the other end surface of the boundary frame facing the negative conductive wire frame;

[0016] The positive conductive wire frame has a protruding block portion 1 protruding from the corresponding embedding groove 1, the positive terminal of the electrical function module is embedded in the embedding groove 1, and the positive conductive wire frame abuts against the positive terminal of the electrical function module through the protruding block portion 1 to establish a positive connection;

[0017] The negative conductive wire frame has a second protrusion corresponding to the second embedding groove, and the negative terminal of the electrical function module is embedded in the second embedding groove. The negative conductive wire frame abuts against the negative terminal of the electrical function module through the second protrusion to establish a negative connection.

[0018] Through the above technical solution, the several embedding grooves 1 and 2 opened in the dividing frame correspond to the positions of the positive / negative conductive wire frames on both sides respectively, and the positive terminal and the negative terminal of the electrical function module are respectively embedded in the embedding groove 1 and the embedding groove 2. The inner walls of the embedding groove form a circumferential constraint on the connection end, thereby improving the installation stability; the positive conductive wire frame is embedded in the embedding groove 1 through the protrusion part 1 to abut against the positive terminal of the electrical function module, and the negative conductive wire frame is embedded in the embedding groove 2 through the protrusion part 2 to abut against the negative terminal of the electrical function module. This embedding structure enables the protrusion part and the electrode to achieve surface contact and conduction in the embedding groove, realizes electrode positioning, and ensures that the current path transmission is feasible, eliminating the welding process, shortening the assembly time, and further shortening the production cycle.

[0019] Preferably, the boundary frame is provided with a fixing hole, and the positive conductive wire frame and the negative conductive wire frame are both provided with a fixing column on a side close to the boundary frame for plugging and cooperating with the fixing hole.

[0020] Through the above technical solution, when the three-layer frame is stacked, the conductive frame assembly is precisely assembled through the interlocking of the fixing columns and the fixing holes, forming a mechanical limit. The plug-in structure fixes and aligns the relative positions of the positive / negative conductive wire frame and the dividing frame. The dividing frame serves as an installation base to improve the overall structural strength.

[0021] Preferably, the boundary frame is configured as a circuit board, the positive conductive wire frame and the negative conductive wire frame are integrally formed on upper and lower end surfaces of the circuit board, and the electrical function module is provided on the circuit board.

[0022] Through the above technical solution, the dividing frame adopts a circuit board, and the positive conductive wire frame and the negative conductive wire frame are integrally formed on the upper and lower end surfaces of the circuit board through welding / electroplating / bonding processes to form a double-sided conductive integrated structure. At the same time, it has two independent conductive units that do not contact each other. The surface of the circuit board integrates an array of electrical function modules. The positive conductive wire frame and the negative conductive wire frame are connected to the electrical function module to supply power to the electrical function module. The conductive frame assembly and the functional module are integrated into a single prefabricated part, which is smaller in size than the split design and is easier to assemble in the cavity for use, thereby improving assembly efficiency and further shortening the production cycle.

[0023] Preferably, the positive conductive wire frame, the boundary frame and the negative conductive wire frame may be made of non-metallic materials, and the surfaces of the positive conductive wire frame and the negative conductive wire frame are plated with a conductive metal surface layer.

[0024] Through the above technical solution, the surface of the conductive wire frame made of non-metallic material is plated with a conductive metal layer (such as copper or iron), so that the conductive wire frame has conductive ability. The plating layer is integrally formed with the electrode frame body, and the current is transmitted on the surface of the electrode frame through the plated metal surface, thereby reducing costs.

[0025] Preferably, the building block body includes a base, which is provided with the cavity, and an edge of the base is provided with a first avoidance groove, the first avoidance groove connects the cavity to the outside, and the first avoidance groove is provided in a one-to-one correspondence with the electrical connection contact;

[0026] A cover plate is arranged on the base, and the cover plate covers the opening of the cavity. The cover plate is provided with a second avoidance groove corresponding to the position of the first avoidance groove. The electrical connection contacts are embedded in the first avoidance groove and the second avoidance groove, so that the electrical connection contacts can be exposed to the outer wall of the building block body to form a contact area.

[0027] Through the above technical solution, the base and the cover form a cavity that runs through the end faces of both sides of the building block through the precise alignment of the first and second avoidance grooves, and the contact area of the positive / negative terminals is confined to the cavity and exposed on the end faces of both sides of the building block. When adjacent building blocks are spliced in an upright or any inclined angle, the magnetic adsorption force automatically aligns the avoidance cavities of the two building blocks. Regardless of the splicing direction, the exposed positive / negative terminal contact areas achieve contact overlap across the building blocks, ensuring stable conduction of the conductive path, so that the physical connection and circuit conduction can be completed simultaneously when the building blocks are spliced at any angle, thereby improving the freedom of construction and the reliability of conductivity.

[0028] Preferably, a mounting groove is formed between the base and the cover plate, and the mounting groove is used for mounting the magnetic component;

[0029] A snap-fitting groove is formed between the base and the cover plate, the snap-fitting grooves are arranged one-to-one corresponding to the electrical connection contacts, the snap-fitting grooves are respectively connected to the avoidance groove 1 and the cavity, and when the front end of the electrical connection contact is embedded in the avoidance groove 1, the rear end of the electrical connection contact is snap-fitted into the snap-fitting groove;

[0030] Each side of the building block body is provided with at least one set of electrical connection contacts.

[0031] Through the above technical solution, each magnetic part is snap-fitted and installed in the installation groove between the base and the cover plate, ensuring that the direction is controllable during magnetic splicing and improving the installation position positioning of the magnetic parts.

[0032] When the conductive frame assembly is installed in the inner cavity, the snap-fitting grooves of the positive terminal and the negative terminal are embedded in the corresponding snap-fitting grooves in a recessed form, forming a mechanical interlock between the terminal and the building block body. The fit between the snap-fitting groove and the locking portion limits the lateral displacement of the terminal, so that the electrical connection contacts are always stably exposed to the building block body. The double locking of the snap-fitting groove and the locking avoidance groove improves the installation stability of the assembly.

[0033] Each side of the building block body is integrated with at least one set of electrical connection contacts. The conductive frame assembly is extended into multiple matching sets of positive / negative terminals according to the number of polygonal sides. When any two sides are spliced together through magnetic adsorption, the magnetic parts of the corresponding sides are precisely aligned to generate adsorption force. At the same time, the positive / negative terminals on that side are in contact with the same terminals of the adjacent building blocks to obtain current flow. Various edge-to-edge splicing methods can complete power transmission through the contact group, improving assembly flexibility and circuit scalability.

[0034] Preferably, the electrical function module is a light emitting device, which includes a power frame having at least one positive connection terminal and at least one negative connection terminal, wherein the positive connection terminal contacts the positive conductive wire frame, and the negative connection terminal contacts the negative conductive wire frame, thereby forming current conduction;

[0035] The light-emitting unit is arranged on the power-on frame, and the two ends of the light-emitting unit are respectively connected to the positive connection end and the negative connection end, and is used to emit light after being powered on.

[0036] Through the above technical solution, the positive / negative connection ends of the power-on frame are in direct contact with the surfaces of the positive / negative conductive wire frames respectively, and the conductive plating of the electrode frame is used to form a conductive path to trigger the light-emitting unit to light up. The current completes the circuit from the positive terminal → positive conductive wire frame → positive connection end → light-emitting unit → negative connection end → negative conductive wire frame → negative terminal, triggering the light-emitting unit to light up. The modular design allows the light-emitting device to be directly embedded in the building block cavity and fixed to the conductive frame assembly along with the power-on frame. During assembly, the circuit integration can be completed by simply aligning the contact surface of the bracket connection end and the electrode frame. The rigid contact between the power-on frame and the conductive wire frame reduces the risk of circuit breakage caused by the shaking of the building blocks, forming a uniform and stable light source output inside the transparent building blocks.

[0037] Preferably, the electrical function module is a power supply device, and the power supply device includes a storage board;

[0038] A circuit board connected to the storage board, the circuit board being provided with a switch button, the switch button including a first button and a second button, and the circuit board also being provided with a charging interface for receiving a plug to supply power to the storage board;

[0039] The cover plate is provided with a first clearance hole at a position corresponding to the switch button, and a second clearance hole at a position corresponding to the charging port.

[0040] Through the above technical solution, the storage plate and circuit board of the power supply device are fixed in the cavity, and the positive / negative poles of the circuit board are respectively connected to the positive / negative conductive wire frames of the conductive frame assembly to form a power supply circuit; the first button and the second button are aligned with the two clearance holes and pass through them, and can be pressed for use. When the first button is pressed, the circuit board is triggered to be turned on or off, and current flows from the storage plate to the circuit board. The positive conductive wire frame and the negative conductive wire frame cooperate with the conductive path of the adjacent building blocks to transmit, driving the light-emitting device in the adjacent building block to work, and pressing the second button is used to switch the brightness; the charging port passes through the clearance hole 2, and when the charging port is connected to the external plug, it can charge the storage plate through the circuit board, integrating the power supply, charging and control functions into the single building block, realizing continuous power supply and flexible start and stop of the multi-building block system. At the same time, the modular design ensures convenient disassembly and maintenance, and improves the functional scalability and ease of use of the building block system.

[0041] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:

[0042] 1. This technical solution integrates a conductive frame assembly into the main body of the building block. The conductive frame assembly includes a positive conductive wire frame, a dividing frame, and a negative conductive wire frame stacked in sequence. The positive conductive wire frame is connected to the positive terminal, and the negative conductive wire frame is connected to the negative terminal. The overall design of the conductive frame assembly is quickly installed in the cavity, that is, the positive and negative terminals are connected and energized after magnetic attraction, replacing the internal wire layout, optimizing the assembly process, and shortening the production cycle;

[0043] 2. This technical solution integrates the positive conductive wire frame and the negative conductive wire frame into a single prefabricated part on the upper and lower end surfaces of the circuit board, forming a double-sided conductive integrated structure. The volume is smaller than the split design and it is easier to assemble in the cavity, thereby improving assembly efficiency and further shortening the production cycle.

[0044] 3. This technical solution installs the electrical connection contacts in the avoidance groove between the base and the cover, so that the contact area is exposed on the end faces of the building block on opposite sides. The contacts are automatically aligned during magnetic splicing, achieving synchronous physical connection and stable conductive path for splicing at any angle, taking into account the freedom of multi-directional construction and conductive reliability.

[0045] 4. This technical solution can be set as a light-emitting device or a power supply device through the electrical function module, with different functions and uses, thus expanding practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0072] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0073] Example 1:

[0074] See also Figure 1 A luminous magnetic building block includes a building block body 1. The building block body 1 is square, that is, it has four edges of equal length, and each edge has magnetic attraction and electrical connection capabilities.

[0075] See also Figure 2 、 Figure 3 and Figure 4The building block body 1 includes a base 11 and a cover 12, both of which are made of translucent material that allows light to pass through; the cover 12 is embedded in the open side of the base 11 and is fixed to the base 11 through a snap-fit structure, and a cavity 3 is formed inside when closed; a mounting groove 9 is spliced between the base 11 and the cover 12, and there are eight mounting grooves 9, with two mounting grooves 9 corresponding to each edge; the building block body 1 is provided with a plurality of magnetic parts 2, which are preferably permanent magnets, and each magnetic part 2 is embedded in the corresponding mounting groove 9 one by one.

[0076] The magnetic part 2 is magnetized along its own thickness direction so that its two ends along the thickness direction are N poles and S poles respectively. In the two mounting grooves 9 at each edge position, the two magnetic parts 2 are installed in a polarity complementary manner, that is, the N pole of one magnetic part 2 is embedded toward the bottom of the mounting groove 9, and the other magnetic part 2 is relatively rotated 180° so that the S pole is embedded toward the bottom of the mounting groove 9. The magnetic parts 2 on each side follow the above-mentioned magnetic pole configuration rules to ensure the symmetry of the magnetic pole distribution on each edge of the building block. This layout ensures that when adjacent building blocks are docked through the edges, even if one of the building blocks is rotated 180 degrees, its magnetic part can still form polarity complementarity with the magnetic part on the corresponding edge of the adjacent building block, thereby achieving reliable adsorption.

[0077] It also includes a conductive frame assembly 4, which is installed in the cavity 3 with an adapted contour, and includes a positive conductive wire frame 41, a dividing frame 4 and a negative conductive wire frame 43. The three-layer frame is stacked from top to bottom; wherein, the dividing frame 42 is located between the positive conductive wire frame 41 and the negative conductive wire frame 43, and plays an isolating role to prevent the two from contacting and short-circuiting. The position of the positive conductive wire frame 41 is set close to the cover plate 12; the material of the positive conductive wire frame 41 and the negative conductive wire frame 43 is non-metallic material, and the conductive effect is achieved by plating a conductive metal surface layer on the surface. Alternatively, the material of the positive conductive wire frame 41 and the negative conductive wire frame 43 can also be made of metal materials such as iron or copper.

[0078] There are several fixing holes 14 running through the dividing frame 42. Correspondingly, the positive conductive wire frame 41 and the negative conductive wire frame 43 are each provided with a plurality of fixing posts 15 in the corresponding fixing holes 14 near the side of the dividing frame 42. During assembly, the fixing posts 15 are respectively embedded in the corresponding fixing holes 14 to achieve relative fixation between the three layers of the frame.

[0079] The conductive frame assembly 4 extends outwardly to form at least one pair of electrical connection contacts 5 with opposite polarities, each of which includes a positive terminal 51 and a negative terminal 52. This embodiment shows a situation where four pairs of electrical connection contacts 5 are provided, and the four pairs of electrical connection contacts 5 are arranged corresponding to the four edges of the building block body 4, wherein the positive terminal 51 is integrally connected to the positive conductive wire frame 41, and the negative terminal 52 is integrally connected to the negative conductive wire frame 43; during the installation of the conductive frame assembly 4, each positive terminal 51 and negative terminal 52 can be installed in the corresponding avoidance cavity, and at this time, each pair of positive terminals 51 and negative terminals 52 are respectively located on the opposite sides of the two magnetic parts 2 on the corresponding sides of the building block body 1, thereby increasing the magnetic contact area and reducing the magnetic flux attenuation, and the adsorption of the magnetic part 2 is more stable; and as shown Figure 2 and Figure 5 As shown, a plurality of snap-fit grooves 13 are formed between the base 11 and the cover plate 12. Each snap-fit groove 13 corresponds to each avoidance groove 71. The snap-fit grooves 13 respectively connect the corresponding avoidance groove 71 and the cavity 3. When the front end of the electrical connection contact 5 is embedded in the avoidance groove 71, its rear end is correspondingly embedded in the corresponding snap-fit groove 13, thereby further realizing positioning.

[0080] When two building block bodies 1 are magnetically spliced together through the magnetic member 2, the positive terminals 51 on both sides of the attraction position will contact each other to achieve positive pole interconnection; at the same time, the negative terminals 52 on both sides of the attraction position will also be connected accordingly to achieve negative pole interconnection; a conductive path is established on the splicing surface to meet the requirements of forming a complete current loop. It is further explained that the specific positions of each pair of positive terminals and negative terminals, in addition to those shown in this embodiment, can also be set in the area between two adjacent magnetic members or other suitable positions.

[0081] The contact areas of the positive terminal 51 and the negative terminal 52 are exposed on the side and upper and lower end surfaces of the building block body 1, providing four pairs of positive terminal 51 and negative terminal 52 combinations for current to flow and form a circuit; similarly, when two building blocks are spliced together in the vertical direction, their splicing surfaces can also contact each other through their respective exposed positive and negative terminals to form a conductive path, thereby achieving electrical connectivity when spliced in different directions.

[0082] See also Figure 4, also includes an electrical function module 6, the electrical function module 6 is a light-emitting device 16, which includes a power-on frame 161 and a light-emitting unit 162, the power-on frame 161 is provided with at least one positive connection terminal 17 and at least one negative connection terminal 18, and the embodiment shows that the power-on frame 161 is in an X-shape, and two positive connection terminals 17 and two negative connection terminals 18 are symmetrically extended from both ends; the dividing frame 42 is provided with a embedding groove, specifically including a embedding groove 191 and a embedding groove 2 192, and there are two embedding grooves 191 and 192. Since the dividing frame 42 is rectangular, the two The first embedding groove 191 and the second embedding groove 192 are respectively located at the four corners of the dividing frame 42; among them, the two embedding grooves 191 are recessed in the end surface of one side of the dividing frame 42 close to the positive conductive wire frame 41, for the two positive connection terminals 17 to be embedded in a one-to-one correspondence, and two protruding blocks 201 are protruding on the positive conductive wire frame 41, and the protruding blocks 201 are embedded in the corresponding embedding grooves 191 and contact the positive connection terminals 17 therein, thereby establishing a positive electrical connection. Alternatively, the shape of the power supply frame 161 can also be set to a rectangle, triangle, cross, flower shape or other shapes.

[0083] Correspondingly, the two second embedding grooves 192 are recessed in one side of the dividing frame 42 close to the negative conductive wire frame 43, and the two negative connecting terminals 18 are embedded in the two second embedding grooves 192. The negative conductive wire frame 43 protrudes with two second protrusion parts 202. The two second protrusion parts 202 are arranged in correspondence with the positions of the two second embedding grooves 192 one by one. The two second protrusion parts 202 are aligned with the two second embedding grooves 192 and embedded. At this time, the second protrusion part 202 is crimped on the corresponding negative connecting terminal 18. The negative conductive wire frame 43 establishes an electrical connection with the negative connecting terminal 18 through the second protrusion part 202, thereby establishing an electrical connection of the negative pole.

[0084] The light-emitting unit 162 is preferably an LED lamp, which is installed on the power-on rack 161. This embodiment shows that each bracket section of the power-on rack 161 is provided with a light-emitting unit 162. Each lamp tube is arranged across the opposite sides of the branch bracket, so that both the front and back sides of the lamp tube can emit light when current flows through, ensuring that the light of the light-emitting unit 162 inside the building block is visible on both sides after power is applied.

[0085] It is further explained that the design of the power-on rack is flexible: on the premise of ensuring that the power-on rack 161 has at least one positive connection terminal 17 and one negative connection terminal 18 to meet the basic electrical connection requirements, it can be freely extended to add several positive connection terminals 17 and several negative connection terminals 18 according to its shape and functional requirements to adapt to the internal layout and electrical connection requirements of building blocks of different shapes.

[0086] See also Figure 10 On each edge of the building block body 1, the position of each pair of positive terminal 51 and negative terminal 52 combination is set in the central area between two adjacent magnetic parts 2 on the same side of the edge.

[0087] See also Figure 11 The shape of the power-on frame 161 is preferably rectangular. The power-on frame 161 is provided with a positive connection terminal 17 and a negative connection terminal 18. The positive connection terminal 17 and the negative connection terminal 18 are respectively located in the middle of the opposite sides of the power-on frame 161 and extend outward. The positions of the first embedding groove 191 and the second embedding groove 192 correspond to the positive connection terminal 17 and the negative connection terminal 18. The light-emitting unit 162 is arranged along the rectangular outline of the power-on frame 161.

[0088] See also Figure 12 The shape of the power-on rack 161 is preferably a cross, which naturally forms four symmetrically extended branches. The power-on rack 161 is symmetrically provided with two positive connection terminals 17 and two negative connection terminals 18. Each connection terminal is symmetrically distributed at the corresponding position of the cross structure to ensure the balance of the electrical connection. The two negative connection terminals 18 are respectively located at the ends of the other two branches; the light-emitting units 162 are provided on the four branches of the power-on rack 161.

The two positive connection terminals 17 are located at the corner positions of one set of diagonal vertices of the power-on rack 161, and the two negative connection terminals 18 are correspondingly located at the corner positions of the other diagonal vertices; the light-emitting unit 162 is arranged along the rhombus outline of the power-on rack 161. Alternatively, the shape of the power-on rack 161 can also be other suitable shapes.

[0097] See also Figure 21 The shape of the building block body 1 is preferably a hexagon, and the lengths of its six sides are equal.

[0098] To further illustrate, the shapes of the internal structures (such as the power supply frame, magnetic component layout, etc.) of the building block bodies of the above shapes can be adaptively designed and adjusted according to the outline of the body.

[0099] like Figure 22 and Figure 23 As shown, since each side of the building block body 1 is provided with at least one set of electrical connection contacts 5 and magnetic parts 2, building block bodies 1 of different shapes can be freely combined into various forms through magnetic adsorption. While being magnetically spliced, the magnetic positions establish conductive paths through the electrical connection contacts 5. When an external power supply is connected, current can trigger the built-in electrical function module through these contact paths, thereby realizing the luminous function.

[0100] The specific working process of this program is as follows:

[0101] This technical solution is provided with a stacked conductive frame assembly 4 through the cavity 3, and a gap is left between the two conductive frames to avoid contact. The positive / negative terminals 52 connected to the positive / negative conductive wire frames 43 respectively extend outward from the electrode frame to the side surface of the building block body 1; the positive electrode of the electric function module 6 is connected to the positive conductive wire frame 41, and the negative electrode is connected to the negative conductive wire frame 43. When the building block body 1 is connected to the power supply, the current path is along the positive terminal 51, the positive conductive wire frame 41, the electric function module 6, the negative conductive wire frame 43, and the negative terminal 52 to achieve complete Circuit, and when two building blocks are magnetically spliced together through the magnetic part 2, the magnetic force drives the positive terminal 51 and the negative terminal 52 on both sides of the splicing surface to contact each other accurately, and the current is transmitted to the adjacent building blocks, automatically establishing a conductive path across the building blocks. The splicing of multiple building blocks can trigger functions such as lighting, power supply or sound, realizing an intelligent interactive experience of splicing and powering. This design integrates the conductive frame component 4 and is installed in the inner cavity to replace the traditional wire part, optimizes the internal wiring, and makes assembly faster, thereby shortening the production cycle.

[0102] Example 2:

[0103] See also Figure 6 、 Figure 7 and Figure 8 , a luminous magnetic building block, the difference from embodiment 1 is that the conductive frame component 4 is in the shape of a sheet-like structure, and the dividing frame 42 is set as a circuit board 402, such as Figure 7As shown, the positive conductive wire frame 41 and part of the negative conductive wire frame 43 can be sprayed with (aluminum foil or copper foil) and then integrally arranged on the front and back of the circuit board 402 and laid along the outline of the boundary frame 42, as shown in FIG. Figure 8 As shown, only a negative conductive wire frame 43 is provided on the back of the circuit board 402, and the negative conductive wire frame 43 on the back passes through the circuit board 402 and is connected to the negative conductive wire frame 43 on the front; the positive conductive wire frame 41 and part of the negative conductive wire frame 43 form two independent conductive units, the positive conductive wire frame 41 is integrally extended with four positive terminals 51, and the negative conductive wire frame 43 is integrally extended with four negative terminals 52; the electrical function module 6 is provided on the circuit board 402, the power-on frame 161 is integrally formed on the inner side of the circuit board 402, and the four light-emitting units 162 are integrally connected to the power-on frame 161.

[0104] Example 3:

[0105] See also Figure 9 , a luminous magnetic building block, which differs from Example 1 in that the electric function module 6 is a power supply device 21, which is installed in the cavity 3 and is located on the inner side of the conductive frame assembly 4. The power supply device 21 includes a storage board 211 and a circuit board 212. The circuit board 212 is connected to the storage board 211. A switch button 22 is provided on the circuit board 212, which includes a first button 221 and a second button 222. The cover 12 has two clearance holes 24 corresponding to the positions of the switch buttons 22. The first button 221 and the second button 222 pass through the two clearance holes 24 in a one-to-one correspondence. Pressing the first button 221 can turn the power on or off. Pressing the second button 222 can control the display brightness of the light-emitting unit 162, which is used to cut off the power supply.

[0106] The charging interface 23 and the cover 12 are provided with a second clearance hole 25 at the position corresponding to the charging interface 23. In this example, the plug that can be inserted into the charging interface 23 can be a Type-C standard interface, which is used to connect the charging cable to recharge the battery board 211.

[0107] The specific working process of this program is as follows:

[0108] In this technical solution, the storage battery 211 and the circuit board 212 of the power supply device 21 are fixed in the cavity 3. The positive / negative poles of the circuit board 212 are respectively connected to the positive / negative conductive wire frames of the conductive frame assembly 4 to form a power supply circuit. When the first button 221 in the push switch button 22 is pressed, the circuit board 212 is triggered to conduct, and the current flows from the storage battery 211 to the circuit board 212. The positive conductive wire frame 41 and the negative conductive wire frame 43 cooperate to transmit the conductive path of the adjacent building blocks, driving the light-emitting device 16 in the adjacent building blocks to work. When the second button 222 is pressed, the circuit is cut off and powered off. When an external plug is connected to the charging interface 23, the storage battery 211 can be charged. The power supply, charging and control functions are integrated into this single building block, realizing continuous power supply and flexible start / stop of the multi-building block system.

[0109] Embodiment 4:

[0110] A light-emitting magnetic building block, which is different from Embodiment 1 in that the electrical function module 6 can be set as a sound-emitting device or a display screen. The sound-emitting device can emit sound after being powered on, and the display screen can display numbers or patterns.

[0111] Embodiment 5:

[0112] See Figure 24 and 25 , a light-emitting magnetic building block, which is different from Embodiment 1 in that the power-on frame 161 of the electrical function module 6 is set as a rectangular transparent frame, and the light-emitting unit 162 is arranged inside it. The proportion of the area of the electrical function module 6 in the plane of the cavity 3 is greater than or equal to 80%. The proportion of the light-emitting area is relatively large, and a better light-emitting effect can be obtained.

[0113] The power-on frame 161 can be clamped inside the demarcation frame 42. The positive connection end 17 and the negative connection end 18 are designed as bumps, which protrude from the same side wall of the power-on frame 161 and are arranged at intervals along the length direction. The frame shape of the demarcation frame 42 is in the shape of a "冂" character, which is a square frame lacking one edge. After the positive conductive wire frame 41 and the negative conductive wire frame 43 are installed, a让位 cavity 300 is left between the two frames. The positive conductive wire frame 41 has a positive contact bump 100, and the negative conductive wire frame 43 has a negative contact bump 200. The positive contact bump 100 and the negative contact bump 200 both extend towards the让位 cavity 300. When the side part of the power-on frame 161 is inserted into the让位 cavity, the positive connection end 17 and the negative connection end 18 respectively contact the positive contact bump 100 and the negative contact bump 200.

[0114] Due to process problems, the inside of the power-on frame 161 on this side does not have the condition for arranging the light-emitting unit 162, resulting in the non-light-emitting part on this side. In order not to affect the aesthetics, the non-light-emitting edge is embedded in the让位 cavity, and the positive conductive wire frame 41 and the negative conductive wire frame 43 on both sides are used to jointly block and hide the non-light-emitting part of the power-on frame 161, the positive and negative connection ends, and the positive and negative contact bumps, improving the aesthetics of the appearance of the building block body 1.
