Description

Technical Field

[0001] This invention belongs to the field of assembly toy technology, specifically relating to a multi-point functional building block, building block unit, and building block toy. Background Technology

[0002] With the development of the toy industry, more and more toys incorporating electronic functions and offering enhanced playability have emerged. These include electronic building block toys. These toys consist of multiple interlocking blocks with hollow shells containing batteries, LEDs, and electrical connections. They can be assembled in the same way as traditional building blocks and also emit light. Some of these blocks also have exposed electrodes. When multiple blocks are interlocked and their electrodes make contact, the electrical connections within the blocks form a circuit, causing the LEDs to light up simultaneously. These new types of building block toys offer expanded play options and functions, providing users with more enjoyment.

[0003] However, currently, the shapes of these electronically functional building blocks are limited. A typical set of building block toys usually contains only a few small blocks of a single basic shape, such as small cube-shaped or square-shaped blocks. Other shapes are rare, and there is a lack of larger or more complex building blocks. This severely limits the combinations that users can create when assembling and playing, resulting in high repetitiveness and causing many users to quickly become bored. The main reason is that the internal electrical connection structure of current electronically functional building blocks is quite complex. Even small building blocks contain many components such as LEDs, circuit boards, multiple wires, and numerous electrical contacts. When producing such building blocks, it is necessary to connect multiple wires inside the shell, form multiple electrical contacts through welding, and fix part of the electrical connection structure to the inner surface of the shell. This results in low production efficiency and a long production cycle. If large or complex-shaped building blocks are to be made, using the same LED beads and electrical connection structure as small building blocks will result in unsatisfactory lighting effects, such as uneven or dim lighting. Furthermore, if the number of LED beads is increased, the number of wires and electrical contacts will also need to be increased accordingly, which will further complicate the internal structure and make it difficult to mass-produce and promote its application.

[0004] In addition, soft wires and welded electrical contacts are relatively fragile. Building blocks are prone to collisions and falling to the ground during use and storage, which can easily cause poor contact or even breakage of the wires or electrical contacts inside the blocks, causing the blocks to lose their electronic functions. This is even more pronounced for large building blocks, resulting in a poor user experience.

[0005] Therefore, in order to enable more ways to play with such building block toys and a better user experience, a new type of structural design for large building blocks and / or complex structure building blocks with electrical functions is needed. Summary of the Invention

Since the multi-point electrical functional component includes multiple electrical connection parts and multiple electronic components, forming a three-dimensional radial shape with multiple electronic components as centers, light-emitting devices can be arranged at multiple positions within the building block, resulting in a more uniform and aesthetically pleasing light emission effect. Furthermore, electrode portions conductively connected to the light-emitting devices can be provided at multiple corners and edges of the building block, thus providing a high degree of assembly freedom even for large building blocks. Further, since multi-point electrical connection parts with multiple contact portions are used to conductively connect multiple electronic components, the problem of only connecting some electronic components to the circuit when assembling some electrode portions is avoided. This ensures that regardless of which end is assembled from, as long as at least one pair of positive and negative electrode portions contacts the positive and negative electrode portions of other functional building blocks in polarity-corresponding contact, all multiple light-emitting devices in the multi-point functional building block can emit light simultaneously. Furthermore, since electrical connections are achieved using electrical connection components with a certain degree of rigidity, there is no need to use flexible wires. Moreover, the electrical connection components achieve conductive connection through contact, eliminating the need for welding to form electrical contacts. Therefore, not only is production and assembly more convenient and the production cycle shorter, but it can also reduce or even avoid poor contact, resulting in a better user experience.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the following describes the multi-point functional building blocks, building block units and building block toys of the present invention in detail with reference to embodiments and accompanying drawings.

[0026] Example Figure 1 This is an example diagram of the combined state of the building block toy in this embodiment.

[0027] like Figure 1 As shown, this embodiment provides a building block toy 500, which includes multiple building block units and power supply blocks, and can be assembled into various different shapes for users to play with.

[0028] Each building block unit includes at least two functional building blocks, each functional building block having an electrical functional device capable of emitting sound and / or light. In this embodiment, the electrical functional device is a light-emitting device, preferably an LED. Furthermore, each functional building block and power supply building block has multiple exposed electrode portions. The corresponding contact of the electrode portions of multiple building blocks allows their internal light-emitting devices and electrical connection structures to form a connected circuit, thereby enabling the light-emitting devices of multiple functional building blocks to emit light simultaneously.

[0029] Each building block unit contains multiple functional blocks with matching splicing ends. At least one positive electrode and one negative electrode are distributed on the corner or edge of each splicing end. When there are multiple positive and negative electrodes, any one positive and any one negative electrode can form a pair of electrodes. The functional blocks in the building block unit are spliced ​​together through these splicing ends.

[0030] For example, the building block toy 500 can be assembled into the shape of a castle. The building block toy 400 includes a first building block unit 510, a second building block unit 520, a third building block unit 530, a fourth building block unit 540, a fifth building block unit 550, a sixth building block unit 560, and a powered building block 300. These building block units can also be assembled into other shapes, and the powered building block 300 can be assembled at any position. Alternatively, the building block toy may contain only some of the building block units, or may further include other similar building block units.

[0031] The first building block unit 510 includes a conical functional building block 511 and a cylindrical functional building block 512, which have matching circular splicing ends. Each splicing end has two positive electrode parts and two negative electrode parts on its edge, and the electrode parts are arranged accordingly.

[0032] The second building block unit 520 includes short triangular pyramid functional building blocks 521 and multiple right-angled triangular prism functional building blocks 522. Two right-angled triangular prism functional building blocks 522 are identical in shape and have matching rectangular (rectangular) splicing ends. Each rectangular splicing end has two positive electrode portions and two negative electrode portions at its corners, with the electrode portions correspondingly positioned. The short triangular pyramid functional building blocks 521 and the right-angled triangular prism functional building blocks 522 have matching square (square) splicing ends. The square splicing end of the short triangular pyramid functional building block 521 has two positive electrode portions and two negative electrode portions, and the square splicing end of the right-angled triangular prism functional building block 522 has one corresponding positive electrode portion and one negative electrode portion.

[0033] The third building block unit 530 includes a triangular pyramidal functional building block 531 and a cubic functional building block 532, which have matching square splicing ends. Each square splicing end has two positive electrode parts and two negative electrode parts at its corners, and the electrode parts are set accordingly.

[0034] The fourth building block unit 540 includes a semi-cylindrical functional building block 541 and a cubic functional building block 532, which have matching square splicing ends. Each square splicing end has two positive electrode parts and two negative electrode parts at its corners, and the electrode parts are set accordingly.

[0035] The fifth building block unit 550 includes a triangular prism functional block 551, a trapezoidal functional block 552, and an arched functional block 554. The triangular prism functional block 551 and the trapezoidal functional block 552 have matching square splicing ends. Each square splicing end has two positive electrodes and two negative electrodes at its corners, with the electrodes correspondingly positioned. The trapezoidal functional block 552 and the arched functional block 554 have matching strip-shaped (rectangular) splicing ends. Each strip-shaped splicing end has two positive electrodes and two negative electrodes at its four corners, and each of its two long sides also has one positive electrode and one negative electrode. Furthermore, the arched functional block 554 also has two square splicing ends that can be spliced ​​with other building block units, each square splicing end having two positive electrodes and two negative electrodes.

[0036] The sixth building block unit 560 includes multiple sector-shaped functional building blocks 561 and multiple quarter-cylinder functional building blocks 562. Two sector-shaped functional building blocks 561 have matching first square splicing ends, each with two positive and two negative electrode portions at its corners, the electrodes being correspondingly positioned. Two quarter-cylinder functional building blocks 562 have matching second square splicing ends, each with two positive and two negative electrode portions at its corners, the electrodes being correspondingly positioned. The sector-shaped functional building blocks 561 and quarter-cylinder functional building blocks 562 also have matching arc-shaped splicing ends, each with two positive and two negative electrode portions at its corners, the electrodes being correspondingly positioned. Furthermore, the arc-shaped splicing ends of the sector-shaped functional building blocks 561 are concave arcs, while the arc-shaped splicing ends of the quarter-cylinder functional building blocks 562 are convex arcs.

[0037] exist Figure 1 In the combined design shown, three building blocks are connected to the three ends of the power supply building block 300, and other building blocks are connected to these building blocks respectively, so that the power supply building block and all the multiple functional building blocks are connected to the circuit, so that the light-emitting devices in all the functional building blocks can emit light at the same time.

[0038] In addition, such as Figure 1As shown, the first building block unit 510 is spliced ​​onto one side of the second building block unit 520. A positive electrode and a negative electrode at each end of the cylindrical functional building block 512 contact a positive electrode and a negative electrode at the right-angled triangular prism functional building block 522, respectively, thereby connecting the electronic components in the first building block unit 510 to the circuit. The electrode contact surface of the cylindrical functional building block 512 is an arc-shaped surface, and only one pair of electrodes is magnetically spliced, whereas the splicing end typically has two or more pairs of electrodes. Therefore, compared to the splicing method using the aforementioned splicing end, this splicing method has relatively lower stability but provides more splicing possibilities.

[0039] Among the various functional building blocks mentioned above, the shape-giving functional building block 554 is a large, multi-point functional building block with a more complex shape. At least two points inside it contain electronic components to ensure a lighting effect. The other functional building blocks are all single-point functional building blocks, with one point inside each containing an electronic component.

[0040] Conical functional building block 511, short triangular pyramidal functional building block 521, long triangular pyramidal functional building block 531 and semi-cylindrical functional building block 541 are all single-end functional building blocks with similar structures. Only one end of each block has an electrode part, and the rest is mainly used for shaping. The restrictions on shaping are small, and it is easy to make a variety of different shapes.

[0041] Cylindrical functional building blocks 512, right-angled triangular prism functional building blocks 522, cube functional building blocks 532, equilateral triangular prism functional building blocks 551, trapezoidal functional building blocks 552, sector-shaped functional building blocks 561, and quarter-cylindrical functional building blocks 562 are all multi-ended functional building blocks with similar structures. Each of their multiple ends has an electrode section, providing a high degree of freedom in assembly. Multi-ended functional building blocks can also be made into various different shapes, but they are all cylindrical.

[0042] The structure of the three functional building blocks and the power supply building block will be explained below.

[0043] Figure 2 This is a three-dimensional view of the arched functional building block in this embodiment. Figure 3 This is an exploded view of the arched functional building block in this embodiment. Figure 4 This is a cross-sectional view of the end of the arched functional building block in this embodiment.

[0044] like Figures 2 to 4 As shown, the arched functional building block 554 is shaped like an arch bridge, with one side roughly rectangular and the other side having an arc-shaped archway. The arched functional building block 554 includes a multi-part outer shell 410, a multi-point electrical functional component 420, and multiple magnetic components 430.

[0045] The multi-part housing 410 includes four end-fitting housings 411 and a main body positioning housing 412. In this embodiment, the functional building blocks include light-emitting devices, therefore preferably, the multi-part housing 410 is made of a transparent or translucent material, such as plastic or acrylic.

[0046] The end-fitting housing 411 includes an irregularly shaped plate-like portion and multiple ribs protruding from one side of the irregularly shaped plate-like portion. The irregularly shaped plate-like portion is approximately rectangular in shape with two notches on one side and an arc-shaped notch on the other side. When the arc-shaped notches of the two end-fitting housings 411 face each other, they form an arch-shaped plate.

[0047] Two notches on one side of the end-fitting housing 411 form a first notch 4111 and a first electrode slot 4112. The first notch 4111 is a rectangular notch, and the first electrode slot 4112 is an open groove. The bottom of the slot is the edge of the notch of the irregular plate-like part, and the sidewall of the slot is one side surface of an L-shaped rib or a straight rib next to the notch. Correspondingly, the electrode slot 4112 at one corner is a corner-shaped slot, and the electrode slot at the other corner is a strip-shaped slot. A second electrode slot 4113 is formed next to the arc-shaped notch on the other side of the end-fitting housing 411. It is an open groove, and the bottom of the slot is the edge of the irregular plate-like part. The sidewall of the slot is one side surface of a straight rib.

[0048] Figure 5 This is a perspective view of the main body positioning shell in this embodiment.

[0049] like Figures 2 to 5 As shown, the main body positioning shell 412 is a one-piece molded part, and its overall shape is roughly hollow arch bridge shape, that is, one side is roughly cuboid and the other side has a large semi-circular notch. The main body positioning shell 412 can be regarded as being composed of two mirror-symmetrical irregular cylindrical parts 4121 and a block-shaped part 4122 connecting the two irregular cylindrical parts. Each cylindrical portion 4121 has openings at both ends, and each of the two corners of the opening has a second notch 4123, which is approximately a cuboid notch. A first latching portion 4214 is formed at the second notch 4123 on the cuboid side, which is a right-angled V-shaped plate with a V-shaped outer end. Second latching portions 4218 are also formed at the second notches 4123 at the two corners next to the bridge opening; these are plate-shaped with a straight outer end. A third latching portion 4219 is formed at the junction of each cylindrical portion 4121 and the block portion 4122; this third latching portion is plate-shaped with a straight outer end, and the outer ends of the two third latching portions 4219 are parallel. A partition plate 4125 is formed in the middle of each cylindrical portion 4121 along its height direction. The partition plate 4125 has a device positioning hole 4126 in its middle, which is a triangular through hole.

[0050] The width of the block portion 4122 is smaller than the width of the two cylindrical portions 4121. Two third gaps 4127 are formed on both sides of the block portion 4122 and between the ends of the two cylindrical portions 4121 that are close to each other. That is, a pair of third gaps 4127 are formed on both sides of the narrowest part of the arch shape. The third gaps 4127 are roughly cuboid gaps.

[0051] When the four end-fitting housings 411 are respectively fitted onto the four open ends of the main body positioning housing 412, a closed multi-part outer shell 410 is formed. The corresponding first notch 4111, the first electrode slot 4112, and the second notch 4123 form multiple corner positioning notches located at the corners of the entire outer shell, used to position the electrode parts at the corners; the corresponding two second electrode slots 4113 and the third notch 4127 combine to form two central positioning notches located on both sides of the middle of the entire outer shell (that is, on both sides of the narrowest part of the arch bridge shape), used to position the electrode parts in the middle.

[0052] Two partition plates 4124 divide the interior of the multi-part housing 410 into four cavity sections 410A. The two cavity sections 410A within the same cylindrical section 4121 are connected only through the device positioning holes 4126 on the partition plate 4125. The inner cavities of the two cylindrical sections 4121 are not connected.

[0053] The multi-point electrical functional component 420 includes multiple electrical connection components and two or more electronic components. In this embodiment, there are two electronic components and ten electrical connection components. The multi-point electrical functional component 420 is generally arranged in a three-dimensional, two-point radial shape. The electrical connection components are of three types: four first electrical connection components 421, four second electrical connection components 422, and two third electrical connection components 423. The first and second electrical connection components 421 and 422 are single-point electrical connection components, connected to one circuit board; the third electrical connection components 423 are multi-point electrical connection components, specifically two-point electrical connection components in this embodiment, connected to two circuit boards simultaneously.

[0054] Figure 6 This is a perspective view of the first electrical connection component in this embodiment. Figure 7 This is a perspective view of the first electrical connection component from another angle in this embodiment.

[0055] like Figure 6 and Figure 7 As shown, the first electrical connection component 421 is an integrally molded part, generally in the shape of a Z, and includes a first electrode part 4211, a first fitting part 4212, a first extension part 4213, a first contact part 4214, and a first conductive part 4215.

[0056] The first electrode portion 4211 is a cubic box shape with one open end and an internal cavity for accommodating a magnetic attractor 430. The shape of the first electrode portion 4211 corresponds to the corner block shape of the arched functional block 554. The outer surface of the first electrode portion 4211 includes three interconnected electrode contact surfaces 42111 for contacting the electrode contact surfaces of other functional blocks to achieve conductive communication. The three electrode contact surfaces 42111 are respectively disposed corresponding to the three outer surfaces of the arched functional block 554. The electrode contact surfaces 42111 can be substantially flush with the corresponding outer surface or slightly protrude beyond the corresponding outer surface, preferably slightly protruding beyond the corresponding outer surface.

[0057] The first fitting portion 4212 extends from the two adjacent sides of the first electrode portion 4211, and is in the shape of a bent plate. One side has a first groove 4216, and the other side forms a step with the outer side of the first electrode portion 4211. The first groove 4216 is a right-angled V-shaped groove, and its depth direction is consistent with the opening direction of the first electrode portion 4211. The first groove 4216 matches the first snap-fit ​​portion 4124 and can fit together.

[0058] The first extension 4213 extends from one side of the first fitting portion 4212 and is in the shape of an elongated rod with a bent portion, the outer end of which is in the shape of a semi-circular plate. The first extension 4213 extends obliquely relative to the opening direction of the first electrode portion 4211.

[0059] The first contact portion 4214 extends from one surface of the outer end of the first extension portion 4213, is flattened hemispherical, and has an arc-shaped outer surface.

[0060] The first conductive portion 4215 is used to achieve conductivity, and it at least covers the outer surface of the first contact portion 4214, the three electrode contact surfaces 42111, and a portion of the outer surface of the first fitting portion 4212 and the first extension portion 4213. In this embodiment, the interior of the electrical connection component is a plastic substrate, and the conductive portion is a metal plating covering the entire outer surface of the plastic substrate, which has good conductivity.

[0061] Figure 8 This is a perspective view of the second electrical connection component in this embodiment.

[0062] like Figure 8As shown, the structure of the second electrical connection component 422 is similar to that of the first electrical connection component 421. It has an integrally formed second electrode portion 4221, a second fitting portion 4222, a second extension portion 4223, a second contact portion 4224, and a second conductive portion. The second fitting portion 4222 also has a second groove 4226. The difference is that one side of the second fitting portion 4222 is an arc shape that matches the arc-shaped portion of the arch bridge block, and the second groove 4226 is a straight groove whose depth direction is consistent with the opening direction of the second electrode portion 4221. Furthermore, the second groove 4226 matches the second snap-fit ​​portion 4218 and can fit together. In addition, the second extension portion 4223 also extends obliquely relative to the opening direction of the second electrode portion 4221, but the oblique angle is different.

[0063] Figure 9 This is a perspective view of the third electrical connection component in this embodiment. Figure 10 This is a perspective view of the third electrical connection component from another angle in this embodiment.

[0064] like Figure 9 and Figure 10 As shown, the third electrical connection component 423 includes a third electrode portion 4231, two third fitting portions 4232, two third extension portions 4233, two third contact portions 4234, and a third conductive portion.

[0065] The third electrode portion 4231 is generally rectangular box-shaped, and one side of it has an arc that matches the arch opening of the bridge block. The size of the third electrode portion 4231 is larger than that of the first and second electrode portions. The inner cavity of the third electrode portion 4231 is also formed with a partition structure, dividing its inner cavity into multiple parts, one of which has a size approximately the same as that of the inner cavity of the first electrode portion. The third electrode portion 4231 has three sequentially connected electrode contact surfaces 42311.

[0066] Two third fitting portions 4232 extend outward from opposite sides of the length direction of the third electrode portion 4231. Each third fitting portion 4232 is in the shape of a bent plate, and has a third groove 4236 on the same side. The groove is a straight groove with the depth direction being the same as the opening direction of the third electrode portion 4231. The third groove 4236 matches the third latch portion 4129 and can fit together.

[0067] Two third extensions 4233 extend outward from the two third fitting parts 4232 respectively, and the third extensions 4233 are also in the shape of a slender rod with a bent portion, and their outer ends are in the shape of a semi-circular plate.

[0068] The two third contact portions 4234 extend from one side of the outer end of the two third extension portions 4233, and are also flattened hemispherical with arc-shaped outer surfaces.

[0069] The third conductive part is configured the same as the first conductive part.

[0070] That is, the third electrical connection component 423 can simultaneously connect one electrode to two electronic components.

[0071] Electronic component 424 includes circuit board 4241 and electrical functional device 4242. In this embodiment, circuit board 4241 is triangular in shape, and electrical functional device 4242 consists of four light-emitting devices, which are respectively soldered and fixed to the middle of one side surface of each circuit board 4241. Each corner of the two surfaces of each circuit board 4241 has an electrical contact, with one side having two positive contacts and one negative contact, and the other side having one positive contact and two negative contacts. Each corner has one positive contact and one negative contact on each side. The positive terminal of each light-emitting device is electrically connected to the positive contacts through a circuit pattern on the circuit board, and the negative terminal of each light-emitting device is electrically connected to the negative contacts through a circuit pattern on the circuit board.

[0072] In this embodiment, the electrical contact is an arc-bottomed groove that matches the contact portion of the electrical connection component, and the outer surface of the contact portion can be approximately in contact with the electrical contact.

[0073] Multiple electrical connection components are divided into positive and negative electrical connection components. The electrode portion of the positive electrical connection component (i.e., the first to third electrode portions mentioned above) serves as the positive electrode portion 440A, and the contact portion of the positive electrical connection component contacts the positive electrical contacts on the circuit board 4241; the electrode portion of the negative electrical connection component serves as the negative electrode portion 440B, and the contact portion of the negative electrical connection component contacts the negative electrical contacts on the circuit board 4241. Specifically, one of the third electrical connection components 423 serves as the positive electrical connection component, and its two third contact portions 4234 respectively contact the two positive electrical contacts on the adjacent ends of the two circuit boards 4241; the other third electrical connection component 423 serves as the negative electrical connection component, and its two third contact portions 4234 respectively contact the two negative electrical contacts on the adjacent ends of the two circuit boards 4241.

[0074] In this embodiment, the metal plating of the positive electrode electrical connection component and the metal plating of the negative electrode electrical connection component are different colors. The metal plating of the positive electrode electrical connection component is gold, and the material of the gold plating can be, for example, copper or a copper-zinc alloy; the metal plating of the negative electrode electrical connection component is silver, and the material of the silver plating can be, for example, aluminum, zinc or a zinc alloy. In an alternative embodiment, the metal plating of the positive electrode electrical connection component and the negative electrode electrical connection component can also be different colors, as long as the colors are different and easy for the user to distinguish.

[0075] like Figure 2 and Figure 3As shown, the multiple electrode sections at the corners and center of the arched functional building block 554 are staggered. At the four corners at both ends of its length direction, there are two positive electrode sections 440A and two negative electrode sections 440B, respectively located at the two corners on the diagonal lines of those ends (i.e., two positive electrode sections on one diagonal and two negative electrode sections on the other). On one side of the width direction, the center is a positive electrode section 440A, and the two corners on either side of it in the length direction are negative electrode sections 440B; on the other side of the width direction, the center is a negative electrode section 440B, and the two corners on either side of it in the length direction are positive electrode sections 440A.

[0076] The magnetic attractor 430 is used to achieve magnetic attraction between the arched functional building block 554 and other functional building blocks. Preferably, the magnetic attractor 430 is a permanent magnet. In this embodiment, the magnetic attractor 430 is a cuboid magnet, the size of which is slightly smaller than the inner cavity size of the first electrode portion. It can be accommodated in the inner cavity of each electrode portion, and the inner cavity size allows the magnetic attractor 430 to only translate and rotate slightly within the inner cavity, but not rotate significantly. Therefore, its polarity does not change its correspondence with the outer shell and the contact surfaces of each electrode.

[0077] In this embodiment, the magnetic chuck 430 is magnetized along its own thickness direction, with its two ends in the thickness direction being the N pole and the S pole, respectively. Two magnetic chucks 430 at each end of each edge of the multi-part housing 410 are installed in a complementary polarity configuration. That is, of the two magnetic chucks 430 corresponding to each edge, the N pole of one magnetic chuck 430 faces the apex of the triangular pyramid, while the other magnetic chuck 430 is rotated 180 degrees so that its S pole faces the apex of the triangular pyramid. The two magnetic chucks 430 corresponding to each base edge follow the above magnetic pole configuration rule, ensuring the symmetry of the magnetic pole distribution at each edge. This layout allows the arched functional block 554 to be freely and self-alignedly assembled with another functional block having the same magnetic chuck configuration.

[0078] During assembly, multiple electrical connection components containing magnetic attractants can be assembled at corresponding positions on the upper end of the main body positioning housing 412. Then, two end-fitting housings 411 are fitted onto the upper end. Next, the main body positioning housing 412, with multiple electrical connection components already assembled at one end, is flipped over. Two electronic components 424 are then placed into the component positioning hole 4126 in the middle. Afterward, multiple electrical connection components containing magnetic attractants are assembled at corresponding positions on the upper end (i.e., the other end) of the main body positioning housing 412. Finally, two end-fitting housings 411 are fitted onto the upper end, completing the assembly of the arched functional building block 554. Following this, laser welding can be performed between the edges of each end-fitting housing 411 and the corresponding edges of the main body positioning housing 412 to secure them together.

[0079] After assembly, each electrode is fitted and fixed in its corresponding positioning notch, and the groove on the electrical connection component engages with its corresponding snap-fit ​​part. This fixes the electrodes in multiple directions, preventing displacement or deflection of the electrical connection component. Furthermore, the circuit board is roughly fitted into the device positioning hole, and each corner of its two surfaces is pressed down by an electrical connection component, thus securing the circuit board and its light-emitting devices.

[0080] In addition, it can be seen that there is no obstruction between the electrical functional device 4242 (light-emitting device) and the corresponding end-fitting housing 411, and there is also basically no obstruction between the electrical functional device 4242 and the housing surface corresponding to the main body positioning housing 412. Therefore, the light emitted by the light-emitting device can be well transmitted.

[0081] Since the positive and negative terminals of each electrical functional device 4242 are electrically connected to each positive and negative contact on the corresponding circuit board 4241, and the electrical connection component is in contact with the corresponding electrical contact, and the two circuit boards 4241 are also electrically connected through two third electrical connection components 423, as long as any one of the five positive electrode portions 440A and any one of the negative electrode portions 440B on the arched functional building block 554 is in polarity-corresponding contact with the electrode portions of other functional building blocks, positive and negative interconnection is achieved, and a conductive path is established, so that the electrical functional components of multiple functional building blocks form a complete current loop, all the light-emitting devices in these functional building blocks can emit light simultaneously.

[0082] If one of the functional building blocks is assembled incorrectly, or the polarities do not match (i.e., the positive electrode of the functional building block is in contact with the negative electrode of another functional building block), a complete current loop cannot be formed, and none of the assembled functional building blocks will emit light. By combining the positive and negative electrode parts of different colors, users can easily find out if the assembly is incorrect.

[0083] For example, the multi-point functional building block is a relatively large arch-shaped block. In alternatives, the multi-point functional building block can also be other relatively large basic shapes, such as cuboids, trapezoids, fan-shaped blocks, etc., or it can be other complex shapes, such as star-shaped blocks. The electronic components inside the multi-point functional building block can also be two or more, for example, three, with adjacent electronic components connected by one or more third electrical connection components.

[0084] Other functional building blocks are single-point functional building blocks, each containing only one electronic component. The electrical functional components radiate outwards from this electronic component. Otherwise, their structure is similar to multi-point functional building blocks. Their structure will be briefly described below.

[0085] Figure 11 This is a three-dimensional view of the short triangular pyramidal functional building block in this embodiment. Figure 12 This is an exploded view of the short triangular pyramidal functional building block in this embodiment. Figure 13 This is a perspective view of the housing in this embodiment.

[0086] like Figures 11 to 13 As shown, the single-end type functional building block is illustrated by taking the short triangular pyramid functional building block 521 as an example. It is triangular pyramid in shape with a square base. The end with the base is the splicing end. The four corners of the splicing end are provided with two positive electrode parts 2211A and two negative electrode parts 2211B, which are distributed diagonally.

[0087] The single-ended functional building block includes a two-part outer shell 210, a planar electrical functional component 220, and multiple magnetic components 230.

[0088] The two-part outer shell 210 includes a positioning shell 211 and a shaping shell 212.

[0089] The positioning housing 211 is an integrally formed part, which includes a plate-shaped part with missing four corners (i.e., a relatively wide cross-shaped plate) and a grid-shaped rib protruding from one side surface of the plate-shaped part. The positioning housing 211 has multiple first notches 2111, multiple electrode positioning grooves 2112, device positioning grooves 2113 and multiple positioning protrusions 2114.

[0090] The first notch 2111 is a rectangular notch, formed at each corner of the positioning housing 211.

[0091] The electrode positioning groove 2112 is an open corner-shaped groove used as a snap-fit ​​positioning groove for the electrode part. The electrode positioning groove 2112 is formed next to each of the first notches 2111.

[0092] The device positioning groove 2113 is formed in the middle of one side surface of the positioning housing 211 with grid-like ribs. Small rectangular columnar positioning protrusions 2114 are formed on each side wall of the device positioning groove 2113. The four positioning protrusions 2114 have the same protrusion height and their upper end face is a plane parallel to the plate-like part.

[0093] The housing 212 is a one-piece molded part, and its overall shape is roughly a triangular pyramid with one open end and a missing corner. The housing 212 has multiple second notches 2121, multiple latching parts 2122, multiple magnet limiting parts 2123, and multiple supporting steps 2124.

[0094] The second notch 2121 is a trapezoidal notch, formed at each corner of the opening end of the shell 212, and is provided corresponding to each of the first notches 2111.

[0095] The latching part 2122 is formed on the inner side of each edge of the shaped housing 212. The latching part 2122 is a right-angled V-shaped plate with its outer end in a V shape, and the open end of the V faces the corresponding edge of the shaped housing 212.

[0096] A triangular pyramidal groove is formed between the snap-fit ​​portion 2122 and the edge of the housing 212. A magnet limiting portion 2123 is also formed in the groove. It is a corner plate that fits against the edge of the housing 212. Its outer end is V-shaped, with the opening end of the V facing the inside of the housing 212. The outer end of the magnet limiting portion 2123 is located further inside the housing 212 than the outer end of the snap-fit ​​portion 2122. A roughly trapezoidal truncated space is formed between the edge of the housing 212, the snap-fit ​​portion 2122 and the magnet limiting portion 2123 to accommodate the magnetic attractant 230 and limit its position.

[0097] The support step 2124 is elongated and formed on the inner edge of the opening end of the housing 212. The support step 2124 is closer to the edge of the opening end of the housing 212 than the end of the snap fastener 2122. The support step 2124 has an elongated support surface facing the opening end of the housing 212.

[0098] Apart from the aforementioned mounting structure at the open end, the rest of the shaped housing 212 is only used for shaping and can be made into various different shapes as needed, such as the aforementioned triangular pyramid, semi-cylindrical, conical, or hemispherical, various columnar shapes (cube, cuboid, triangular prism, etc.).

[0099] When the positioning housing 211 and the shaping housing 212 are combined into one, each of the first notches 2111 and the corresponding second notches 2121 are combined to form positioning notches, and the electrode part can be engaged at the positioning notches to achieve positioning and fixation.

[0100] The planar electrical functional component 220 is generally planar and radial, and includes multiple planar electrical connection parts 221 and electronic parts 222.

[0101] The planar electrical connection component 221 has a similar structure to the first electrical connection component 421, the main difference being that its extension is in the shape of a straight rod, and the electrode portion at one end is in the shape of a shallow trapezoidal box.

[0102] Electronic component 222 also includes circuit board 2221 and electrical functional device 2222. Circuit board 2221 is rectangular and fits into device positioning groove 2113, with one surface supported by multiple positioning protrusions 2114. Electrical functional device 2222 is preferably a light-emitting device, soldered and fixed to the middle of one side surface of circuit board 2221. Its positive and negative terminals are electrically connected to the positive and negative electrical contacts at the corners of circuit board 2221, respectively. The contact portions of the planar electrical connection components 221 of the positive and negative terminals contact the corresponding polarity electrical contacts to achieve conductivity, while also pressing and fixing circuit board 2221 in device positioning groove 2113. As can be seen, there is no obstruction between the light-emitting device and the housing 212, so the light emitted can pass through well.

[0103] Multiple magnetic attractors 230 are also respectively disposed in the inner cavity of the electrode portion of each planar electrical connection component 221, and are limited by the inner cavity and the end of the housing 212. The multiple magnetic attractors 230 are also arranged in a complementary polarity manner.

[0104] After assembly, the electrode portions of each planar electrical connection component 221 are respectively fitted and fixed in the corresponding positioning notches, and the snap-fit ​​portions at the corners of the housing 212 engage with the grooves of the planar electrical connection components 221, thereby fixing and limiting each electrode portion to ensure accurate positioning. Each electrode portion also has three interconnected electrode contact surfaces, corresponding to the three outer surfaces of the triangular pyramid, and preferably protruding slightly beyond the corresponding outer surfaces.

[0105] Other single-ended functional building blocks have similar structures, with the main differences being the shape of the housing 212 and the shape of the electrode portion of the planar electrical connection component 221. In addition, as shown in the conical functional building block 511, the electrode portion can also be located on the edge of the splicing end.

[0106] As shown in the above description of various single-ended functional building blocks, preferably, the cross-sectional dimensions of the single-ended functional building block gradually decrease from its splicing end to its other end. However, single-ended functional building blocks can also be made into cubes, cuboids, cylinders, etc., and mainly only require changing the shape of the shell 212.

[0107] Figure 14 This is a 3D view of the cube-shaped functional building block in this embodiment. Figure 15 This is an exploded view of the three-dimensional functional building block in this embodiment. Figure 16 It is a three-dimensional view of the main body shell.

[0108] like Figures 14 to 16As shown, the multi-terminal functional building block is illustrated by taking the cubic functional building block 532 as an example. It is cubic in shape and includes a three-part outer shell 110, a three-dimensional electrical functional component 120, and multiple magnetic components 130.

[0109] The three-part outer shell 110 includes two end positioning shells 111 and a main body shell 112.

[0110] The structure of the end positioning housing 111 is similar to that of the positioning housing 211. It is generally close to a square plate shape, with a first notch 1111 and an electrode positioning groove 1112 at its corner, but no device positioning groove.

[0111] The main body housing 112 is a square cylindrical shape with openings at both ends. Each of the two opening ends has a second notch 1125 at its corner, which can be combined with the first notch 1111 corresponding to the end positioning housing 111 to form a positioning notch. The corners of the opening ends also have V-shaped latching portions 1123 and magnet limiting portions 1124. A partition plate 1122 divides the inner cavity of the main body housing 112 into two parts. The partition plate 1122 has a device positioning hole 1126 in its center, which is a square through hole.

[0112] The three-dimensional electrical functional component 120 includes multiple three-dimensional electrical connection components 121 and electronic components 122, arranged in a three-dimensional radial pattern centered on the electronic components 122. The three-dimensional electrical connection components 121 have a basically the same structure as the first electrical connection component 421, and are also generally Z-shaped. The electronic components 122 also include a circuit board 1221 and electrical functional devices 1222 (light-emitting devices) fixed on the circuit board 1221. There are two light-emitting devices, each fixed to the center of one of the two surfaces of the circuit board 1221. The positive and negative terminals of each light-emitting device are electrically connected to the positive and negative contacts at the corners of the circuit board 1221, respectively.

[0113] The magnetic 130 is also housed in the inner cavity of each electrode part and is limited by the magnet limiting part 1124 at the corner of the main body housing 112, and the multiple magnetic 130 also adopt a magnetic pole complementary configuration.

[0114] After assembly, the electrode portions of each three-dimensional electrical connection component 121 are respectively fitted and fixed at the positioning notches at the corners of the three-part housing 110, and the multiple three-dimensional electrical connection components 121 are bent and extended to the device positioning holes 1126 inside the three-part housing 110, pressing the corners of the two surfaces of the circuit board 1221, thereby fixing the circuit board 1221 in the device positioning holes. Similarly, it can be seen that there is no obstruction between the light-emitting device and one end of the corresponding three-part housing 110, and the light emitted by the light-emitting device is not blocked.

[0115] like Figure 14 and Figure 15 As shown, each edge of the cubic functional block 532 has a pair of electrodes, namely a positive electrode 1211A and a negative electrode 1211B, which are arranged alternately. The cubic functional block 532 can be regarded as having six splicing ends, each splicing end having two positive electrodes 1211A and two negative electrodes 1211B. Similarly, as long as any positive electrode 1211A and any negative electrode 1211B are in contact with the positive and negative electrodes of other functional blocks in corresponding polarities and connected to the circuit, all the light-emitting devices in the cubic functional block 532 can emit light simultaneously.

[0116] Other multi-ended functional building blocks have similar structures, with the main difference being the different shapes of the end positioning shells 111 and the main body shaping shells 112. For example, the end positioning shell 111 of the fan-shaped functional building block 561 is roughly a curved plate with a missing corner, and the main body shaping shell 112 is a hollow, fan-shaped cylinder with a missing corner. Depending on the corner position of the electrode part, one of the electrode contact surfaces is a concave or convex arc surface. As another example, the end positioning shell 111 of the equilateral triangular prism functional building block 551 is roughly a triangular plate with a missing corner, and the main body shaping shell 112 is a hollow, triangular cylinder with a missing corner. The electrode part is shaped like a corner block of a triangular prism. Furthermore, as shown in the cylindrical functional building block 512, the electrode part can also be located on the edge of the splicing end.

[0117] Multi-ended functional building blocks can also be made into other shapes, such as cuboids, prisms with pentagonal or hexagonal bases, etc.

[0118] Figure 17 This is a 3D view of the power supply building block in this embodiment. Figure 18 This is an exploded view of the power supply block in this embodiment.

[0119] like Figure 17 and Figure 18 As shown, the power supply block 300 is also cubic in shape, and its structure is very similar to that of the cubic functional block 532. It also includes a three-part power supply shell 310 and a three-dimensional power supply functional component 320. The power supply functional component 320 also includes multiple Z-shaped electrical connection receiving parts 321 and electronic parts 322. The difference is that in the power supply block 300, the electronic parts 322 are power supply parts, and the power supply shell 310 has corresponding clearance holes.

[0120] The power supply housing 310 includes an end positioning housing 311, a main body housing 312, and a power supply positioning housing 313. The end positioning housing 311 and the main body housing 312 have the same structure as the end positioning housing 111 and the main body housing 112, respectively. The power supply positioning housing 313 has one strip-shaped through hole and two circular through holes on the basis of the structure of the end positioning housing 111.

[0121] Electronic component 322 includes a connection circuit board 3221, a function circuit board 3222, an energy storage device (battery) 3223, a charging interface 3224, a switch button 3225, and a function button 3226.

[0122] The connecting circuit board 3221 is fitted into the device positioning hole in the middle of the housing and is pressed from both surfaces by multiple electrical connection receiving components.

[0123] The functional circuit board 3222 has through holes on both sides of its edge. One of the positioning housings of the power supply block 300 has a corresponding columnar mounting hole on its inner side, allowing the functional circuit board 3222 to be mounted near the inner surface of the positioning housing using a fastener. The functional circuit board 3222 is electrically connected to the connecting circuit board 3221 via wires.

[0124] The energy storage device 3223 is rectangular in shape and is generally fitted into one of the inner cavities of the power supply housing 310, and is electrically connected to the connecting circuit board 3221 via wires. The positive and negative electrical connection receiving parts 321 are respectively electrically connected to the positive and negative electrical contacts at the corners of the connecting circuit board 3221. The positive and negative terminals of the energy storage device 3223 are electrically connected to the positive and negative electrode portions via corresponding wires and corresponding circuit patterns, positive and negative contacts on the connecting circuit board 3221, thereby enabling the output of electrical energy through each pair of positive and negative electrode portions.

[0125] The charging interface 3224, the switch button 3225, and the function button 3226 are all fixed to one surface of the functional circuit board 3222. The charging interface 3224 is a standard Type-C interface, exposed through a strip-shaped through-hole on the power supply positioning housing 313. The two buttons are exposed through two circular through-holes respectively. The switch button 3225 is used to control the power supply of the energy storage device 3223 to start or stop the power supply, and the function button 3226 is used to switch the corresponding functions, such as switching the voltage output of the energy storage device 3223, thereby changing the brightness of the light-emitting device, etc.

[0126] The multiple electrode sections at the corners of the power supply block 300 are configured the same as those of the multi-terminal functional block, i.e., the positive electrode sections and the negative electrode sections are alternately arranged.

[0127] In addition, the power supply block 300 can also be made into a variety of different shapes with reference to the shape of the above-mentioned multifunctional blocks, but considering versatility, the power supply block 300 is preferably cubic in shape.

[0128] A set of building block toys may contain one or more power-powered building blocks 300 and any number of functional building blocks. The ratio of the number of power-powered building blocks to other functional building blocks (electric functional building blocks) depends on the parameters of the energy storage device, the parameters of each electrical functional device, the structure and parameters of the circuit board, etc. Preferably, the ratio of power-powered building blocks to other functional building blocks can be 1:20-1:50.

[0129] Functions and effects of Example 1 The multi-point functional building block (arched functional building block), building block unit, and building block toy provided in this embodiment include a shell, multi-point electrical functional components disposed on the shell, and multiple pairs of magnetic components. Therefore, it is an electrical functional building block that can be magnetically assembled. Since the multi-point electrical functional components include multiple electrical connection parts and multiple electronic components, forming a three-dimensional radial shape with multiple electronic components as the multi-center, light-emitting devices can be arranged in multiple positions within the building block, making its light-emitting effect more uniform and beautiful. Furthermore, electrode parts that are electrically connected to the light-emitting devices can be set at multiple corners and edges of the building block, thus providing a high degree of assembly freedom for large building blocks. Furthermore, by employing multi-point electrical connection components with multiple contacts to conductively connect multiple electronic components, the problem of only connecting some electronic components to the circuit when some electrode sections are assembled is avoided. This ensures that regardless of which end is assembled, as long as at least one pair of positive and negative electrode sections makes polarity-corresponding contact with the positive and negative electrode sections of other functional building blocks, all multiple light-emitting devices in the multi-point functional building block can emit light simultaneously. In addition, since electrical connection components with a certain rigidity are used to achieve electrical connection, there is no need to use flexible wires. Moreover, since the electrical connection components achieve conductive connection through contact, there is no need to weld to form electrical contacts. Therefore, not only is production and assembly more convenient and the production cycle shorter, but also, during long-term use, it can reduce or even avoid contact problems, resulting in a better user experience.

[0130] In the embodiment, in the multi-point functional building block, multiple electrode parts are fitted and fixed in the corresponding positioning notches, and there will be no displacement or deflection. The remaining electrical connection structures are all housed inside the shell, and the edge of the shell is sealed by laser welding. Therefore, it is difficult for ordinary users to disassemble the three-part shell by hand. Even if there is a collision or drop during use, the shell is not easy to loosen or detach. Small parts such as electronic components will not fall outside the shell, thus avoiding the problem of children accidentally swallowing small parts and providing better safety.

[0131] Furthermore, since the first to third electrical connection components are all bent extensions, each extension has a contact portion at its outer end, which can contact the electrical contacts on the circuit board to achieve conductivity and simultaneously press and fix the circuit board. The circuit board is also embedded in the device positioning hole in the middle of the housing, thus achieving fixation and limitation in multiple directions. Therefore, the multi-point functional building block not only eliminates the need for wires and welding to form contacts, but also eliminates the need for additional fasteners, resulting in a simplified overall structure that is highly suitable for large-scale, efficient production.

[0132] Furthermore, since the electrical connection component has a groove and stepped structure, and the positioning notch of the outer shell has a matching snap part and electrode positioning groove, when one end of the electrical connection component is fitted into the corresponding positioning notch, it can be fixed and limited in multiple directions, which can ensure that each electrode part is in an accurate position and that the corresponding electrode contact surfaces are basically coplanar, thereby further improving assembly efficiency and making magnetic splicing more convenient and smooth for users.

[0133] Furthermore, the electrical connection components are composed of a plastic substrate and a metal plating, thus ensuring good conductivity while possessing a certain rigidity. This allows them to effectively hold the central electronic components in place, and the electrode at one end can also engage well with the corresponding positioning notch. Moreover, they possess a degree of elasticity, making them less susceptible to damage even from impacts such as collisions or drops during use, thereby enhancing the reliability of the multi-point electrical functional component. In addition, the plastic substrate is lightweight, resulting in a lighter overall weight for the multi-point functional building block.

[0134] Furthermore, the metal plating of the positive and negative electrical connection components uses different colors, and the structure of the same type of electrical connection component is the same. This allows users to easily distinguish between the positive and negative electrode parts, and in mass production, only three standard parts (i.e., the first to third electrical connection components) need to be processed, making production more convenient.

[0135] Furthermore, each edge of the multi-point functional building block is equipped with a pair of magnetic attractors with complementary polarities. Therefore, when the multi-point functional building block is spliced ​​with other functional building blocks, the corresponding magnetic attractors are precisely aligned and generate an adsorption force, automatically aligning and connecting the positive and negative electrodes of the two building blocks. In other words, physical splicing and circuit conduction are completed simultaneously through magnetic adsorption, realizing an intelligent interactive experience of powering on immediately after splicing, thus improving the user experience.

[0136] Furthermore, since the shape of the magnetic accumulator matches the shape of the inner cavity of the receiving electrode part, and its size is slightly smaller than the size of the inner cavity, and the receiving electrode part cooperates with the positioning notch to receive and limit the magnetic accumulator, it is easy to install the magnetic accumulator, and after installation, the polarity correspondence of the magnetic accumulator can always be maintained, thereby ensuring the user's long-term user experience.

[0137] In this embodiment, the electrical functional device is a light-emitting device, and the outer shell is made of transparent or semi-transparent material. Since the internal structure can be seen through the outer shell, electrical connection components are used instead of a bunch of messy wires, which also makes the appearance of the multi-point functional building block more aesthetically pleasing.

[0138] In this embodiment, the multi-point functional building block is in the shape of an arch bridge. By setting two light-emitting devices facing opposite directions in two larger inner cavity sections, the building block can emit light more evenly. Furthermore, through the design of the Z-shaped electrical connection component with inclined extensions, there is basically no obstruction between the light-emitting device and the corresponding outer shell section, so the emitted light can pass through well. Therefore, even for a relatively complex shape like an arch bridge, an ideal light-emitting effect can be achieved.

[0139] In this embodiment, a set of building block toys also includes single-ended functional building blocks. Because it adopts a two-part shell and a planar electrical functional component, and the planar electrical functional component is located inside the positioning shell, the modeling shell only needs to have a matching mounting structure at the open end, and there are basically no restrictions on the rest. Therefore, the modeling shell can be easily made into a variety of different shapes. That is, it can easily and cost-effectively expand the shape of the functional building blocks, providing users with more modeling possibilities and play fun.

[0140] In this embodiment, a set of building block toys also includes multi-ended functional building blocks. Because these blocks use a three-part shell and three-dimensional electrical components, each end has multiple pairs of electrodes, providing a high degree of freedom in assembly. Furthermore, this structure only requires the multi-ended functional building blocks to be roughly columnar; by changing the shape of their end positioning shells and main body shells, various shapes can be created, including those with curved outer surfaces, thus providing users with more design possibilities and playful enjoyment.

[0141] In this embodiment, a set of building block toys also includes a power supply block with a built-in energy storage device and multiple pairs of electrodes at its various ends. Therefore, by assembling the power supply block with other functional building blocks, it can provide power. Children do not need to connect the multi-ended functional building blocks to an external battery; they can simply assemble the power supply block like any other multi-ended functional building block, making it more convenient to use. Furthermore, one end of the power supply block also has an exposed charging port, a power switch, and function buttons, allowing for easy charging, power on / off operation, and function switching. In other words, it integrates multiple functions such as power supply, charging, and function control, making it very convenient to use.

[0142] In addition, single-ended functional building blocks, multi-ended functional building blocks, and power supply building blocks also use electrical connection components similar to those in multi-point building blocks, thus also having the advantages of easier production and assembly, shorter production cycle, and higher reliability of electrical connection structure.

[0143] Furthermore, in both single-ended and multi-ended functional building blocks, the structural design of the electrical connection components ensures that there is virtually no obstruction between the light-emitting device and the corresponding outer shell, thus achieving an ideal light-emitting effect.

[0144] Example 2 This embodiment provides a multi-point functional building block, a building block unit, and a building block toy. In this embodiment, the same symbols are assigned to the same constituent elements as in Embodiment 1, and the corresponding descriptions are omitted.

[0145] The difference from Embodiment 1 is that the multi-point functional building block in this embodiment is a cuboid functional building block.

[0146] Figure 19 This is a three-dimensional diagram of the cuboid functional building block in this variation example. Figure 20 This is an exploded view of the cuboid functional building block in this embodiment.

[0147] like Figure 19 and Figure 20 As shown, the cuboid functional building block 555 is cuboid in shape, with a length-to-width ratio of 2:1. It also includes a multi-part outer shell 410, a multi-point electrical functional component 420, and a multi-magnetic component 430.

[0148] The multi-part housing 410 includes two end-fitting housings 411 and a main body positioning housing 412. The two end-fitting housings 411 are generally rectangular plates with notches at the corners and gaps in the middle of both sides in the width direction. The structure of one side with ribs matches the open end structure of the main body positioning housing 412. The main body positioning housing 412 is a rectangular cylindrical tube with notches at the corners and gaps. It has an internal partition plate that divides its interior into two cavities. The partition plate has two spaced-apart device positioning holes 4126, which are square through holes.

[0149] The multi-point electrical functional component 420 also includes ten electrical connection components and two electronic components 422, and the whole is arranged in a three-dimensional radial shape with the two electronic components 422 as two center points. The electrical connection components include eight first electrical connection components 421 and two third electrical connection components 423. Among them, the third groove 4236 on the third electrical connection component 423 is also a V-shaped groove. Correspondingly, the end of the third latching part 4129 on the inner side of the middle of one edge of the main body positioning housing 412 is V-shaped and can be fitted with the third groove 4236.

[0150] Electronic component 422 also includes circuit board 4221 and multiple light-emitting devices. Circuit board 4221 is a rectangular plate that matches the device positioning hole 4126. It is also fitted into the device positioning hole 4126 and is pressed from both surfaces by multiple electrical connection components, thereby being fixed.

[0151] A building block unit may include a cuboid functional building block 555 of this embodiment, an equilateral triangular prism functional building block 551 of embodiment one, and a trapezoidal functional building block 552. The cuboid functional building block 555 and the trapezoidal functional building block 552 have matching rectangular splicing ends. The rectangular splicing ends have six electrode parts, including three positive electrode parts and three negative electrode parts, and the electrode settings are also corresponding.

[0152] Alternatively, a building block unit may also include the cuboid functional building block 555 of this embodiment, the equilateral triangular prism functional building block 551 of Embodiment 1, the trapezoidal functional building block 552, and the arched functional building block 554. For example, the cuboid functional building block 555 can be spliced ​​between the trapezoidal functional building block 552 and the arched functional building block 554.

[0153] In this embodiment, the other structures are basically the same as in Embodiment 1, and will not be described again. Variations This variation is a modification of Embodiment 2. In this variation, the same symbols are assigned to the same constituent elements as in Embodiment 1, and the corresponding descriptions are omitted.

[0154] Figure 21This is a three-dimensional view of the cuboid functional building block in this variation.

[0155] like Figure 21 As shown, compared with Embodiment 2, the cuboid functional building block 555 in this modified example is also cuboid in shape. The only difference is that the outer surface of the multi-part shell 410 includes multiple square facets 413, each square facet 413 being composed of four triangular facets, with the center of the square facet 413 being concave. The outer surface of the end-fitting shell 411 has two square facets 413. Of the four outer surfaces of the main body positioning shell 412, the square outer surface has one square facet 413, and the rectangular outer surface has two square facets 413.

[0156] Figure 22 This is a three-dimensional view of the short triangular pyramidal functional building block in this variation.

[0157] like Figure 22 As shown, similarly, the outer surface of the bipartite shell 210 of the short triangular pyramid functional building block 521 in this modified example also includes multiple facets. Specifically, the outer surface of the positioning shell 211 has a square facet 213; the multiple triangular outer surfaces of the shaping shell 212 each have a triangular facet 214, which is composed of three triangular facets, and the center of the triangular facet 214 is concave.

[0158] Because the outer surface of the shell has concave ridges, the shell has better structural strength, can better disperse external forces, resist deformation, reduce the probability of damage when the functional building blocks fall, and also allows users to hold the building blocks better.

[0159] Furthermore, the facets refract light emitted from the internal light-emitting devices, dispersing the light in various directions. This results in more uniform and softer light, a wider light-emitting range, and the ability to present different brightness and shadows from multiple angles. Moreover, when multiple functional building blocks with facets and different light colors are assembled, the light from these blocks overlaps through facet refraction, leading to a more natural transition in light colors. Therefore, the user experience is improved. Optionally, the facets can have varying thicknesses, such as thinner near the center of each triangular facet and thicker near the edge, or vice versa, to enhance the aforementioned effects.

[0160] In this modified example, the other structures are the same as in Example 2, and will not be described again.

[0161] In addition, the various other shapes of functional building blocks shown in Embodiment 1 can also have similar facets. For example, the outer surfaces of the shell of the cube functional building block can also have square facets, the square outer surface of the fan-shaped functional building block can also have square facets, and its arc-shaped outer surface can also have corresponding arc-shaped facets, that is, facets composed of four curved triangular facets.

[0162] The above embodiments and modifications are merely illustrative of specific implementations of the present invention, and the present invention is not limited to the scope of the description of the above embodiments and modifications. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments, modifications, and descriptions in the specification are only for illustrating the principles of the present invention. Various changes and modifications can be made to the present invention without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.

[0163] For example, in the above embodiments, building block toys are used for user entertainment, especially for children. In alternatives, building block toys can also be used for other purposes. For instance, the electrical functional components in multi-functional building blocks can be light-emitting devices, and these devices can be shaped like numbers, letters, words, symbols, etc., which can be assembled into illuminated statements or mathematical formulas. This can be used for early childhood education, or as interlocking illuminated billboards, illuminated or sound-emitting holiday decorations, etc. Alternatively, if the electrical functional components of the functional building blocks are light-emitting devices, and these devices are energy-efficient and have a long lifespan, the building block toys can also be used as interlocking lighting fixtures.
