Description

Technical Field

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

[0002] Traditional building block toys typically consist of multiple wooden or plastic blocks that can be freely combined into various shapes, but their functions and play methods are relatively limited. In recent years, electrically functional building blocks with light-emitting or sound-emitting capabilities have emerged. These blocks contain electronic devices that emit light or sound, allowing for conventional assembly and expanding the functionality and play possibilities of building block toys. However, current building block toys still have some shortcomings.

[0003] On the one hand, existing electric functional building blocks typically have relatively simple shapes. For example, a set of toys may only contain a few rectangular functional blocks. This severely limits users' creative possibilities when playing, and the gameplay can be repetitive and easily become boring. When used to develop abilities in young children, the scope of ability development is relatively narrow, failing to cultivate children's recognition of different shapes or their ability to observe and plan combinations of various shapes. On the other hand, adding electric functional building blocks of various other shapes would require redesigning the outer shell structure and the internal electrical connection structure, which would significantly increase the cost of building block toys.

[0004] On the other hand, the electrical connection structures in existing electrically functional building blocks are quite complex. For example, a common structure uses circuit boards and wires. During production, each light-emitting or sound-emitting electronic component needs to be connected to the circuit board via wires and then soldered in place. If multiple electrodes are present on the surface of the building block, the light-emitting electronic components also need to be electrically connected to their corresponding electrodes via wires. In other words, during the production and assembly process, multiple wires need to be laid out and connected within the confined space of the building block, forming numerous electrical contacts. This is time-consuming, labor-intensive, and inefficient. Furthermore, during user play and storage, the building blocks are inevitably subject to bumps and falls. The wires and electrical contacts are relatively fragile and prone to poor contact or even disconnection, causing the electrically functional building block to lose its electrical function and resulting in a poor user experience.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the following describes the single-ended functional building block, building block unit and building block toy of the present invention in detail with reference to the embodiments and accompanying drawings.

[0022] Example This embodiment provides a building block toy for user entertainment, comprising multiple functional building blocks that can be magnetically connected and assembled. Each functional building block contains an electrical component capable of emitting light or sound. When multiple functional building blocks are assembled, they form a connected circuit, and each electrical component performs its corresponding electrical function when energized.

[0023] The functional building blocks include single-ended functional building blocks, double-ended functional building blocks, and power supply building blocks, the composition of which will be explained below.

[0024] Figure 1 This is a perspective view of the single-ended functional building block in this embodiment. Figure 2 This is a cross-sectional view of the single-ended functional building block in this embodiment. Figure 3 This is an exploded view of the single-ended functional building block in this embodiment.

[0025] like Figures 1 to 3 As shown, one end of the single-ended functional building block 200 is the splicing end, and one outer surface of the splicing end is the splicing surface 201 (i.e., the square base of the triangular pyramid), which is flat and used for splicing with other functional building blocks. The edge or corner of the splicing end is provided with one or more pairs of magnetic attracting parts and one or more pairs of electrode parts, which are used for magnetic splicing with other functional building blocks and at the same time to achieve conductive connection.

[0026] In this embodiment, the single-ended functional building block 200 is generally in the shape of a triangular pyramid. One end of the square base of the triangular pyramid is the splicing end. Two pairs of electrode parts are provided at the splicing end. Each pair of electrode parts includes a positive electrode part 2211A and a negative electrode part 2211B. The two positive electrode parts 2211A are respectively located at the two corners on one diagonal of the splicing surface 201, and the two negative electrode parts 2211B are respectively located at the two corners on the other diagonal of the splicing surface 201. Each electrode part is also used as a corner piece of the building block.

[0027] In an alternative embodiment, the single-ended functional block 200 may also have other shapes, and the electrode portions may be distributed on the edge of the splicing end. Preferably, the cross-sectional dimensions of the single-ended functional block 200 gradually decrease from the splicing end to the opposite end.

[0028] The single-ended functional building block 200 includes a two-part outer shell 210, a planar electrical functional component 220 disposed on the outer shell 210, and a plurality of magnetic components 230. In this embodiment, the electrical function of the single-ended functional building block 200 is to emit light. Accordingly, the two-part outer shell 210 is made of a transparent or translucent material to allow light to pass through, such as plastic or acrylic material.

[0029] In alternative solutions, the electrical function can also be other functions, such as sound generation. When the electrical function is sound generation, the two-part housing 210 can also be made of an opaque material.

[0030] The two-part outer shell 210 includes a positioning shell 211 and a shaping shell 212. The positioning shell 211 is used to position the electrical functional component 220; the shaping shell 212 is used to form the external shape of the entire building block and is used to cooperate with the positioning shell 211 to position and fix the electrical functional component 220.

[0031] Figure 4 This is a perspective view of the positioning housing in this embodiment.

[0032] like Figures 1 to 4 As shown, 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, multiple positioning protrusions 2114 and multiple support bars 2115.

[0033] The first notch 2111 is a rectangular notch, formed at each corner of the positioning housing 211.

[0034] The electrode positioning groove 2112 is an open corner groove used as a snap-fit ​​positioning groove for the electrode part. The electrode positioning groove 2112 is formed next to each first notch 2111. Its bottom is the edge of the notch of the plate-shaped part, which is V-shaped. Its two side walls are the side surfaces of the ribs set next to the notch of the plate-shaped part. The two side walls are roughly perpendicular to each other and are also roughly perpendicular to the bottom of the groove.

[0035] 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.

[0036] The support strip 2115 is thin and its length direction is consistent with the length direction of its edge. Multiple support strips 2115 are arranged sequentially along the length direction of their respective edges. In this embodiment, four are provided on each side, and there is a gap between two adjacent support strips 2115.

[0037] Figure 5 This is a perspective view of the housing in this embodiment.

[0038] like Figures 1 to 3 as well as Figure 5 As shown, 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.

[0039] 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.

[0040] The latching part 2122 is formed on the inner side of each edge of the shaped housing 212. The latching part 2122 is in the shape of a corner plate and is composed of two mutually perpendicular plate-shaped parts. The surface direction of these two plate-shaped parts is perpendicular to the two side length directions of the shaped housing 212. The outer end of the latching part 2122 is V-shaped, and the opening end of the V faces the corresponding edge of the shaped housing 212.

[0041] 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.

[0042] 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.

[0043] 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. For example, while the positioning housing 211 and the electrical connection structure remain unchanged, the shaped housing 212 can also be made into a cubic box shape, a cuboid box shape, a semi-cylindrical box shape, or an irregular box shape. The outer surface of the shaped housing 212 can also be non-planar, but rather a concave ridge or curved surface, as long as its open end has the mounting structure described above.

[0044] 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.

[0045] The planar electrical functional component 220 includes multiple electrical connection receiving parts 221 and electronic parts 222, wherein the electronic parts 222 are power-consuming parts capable of emitting light; the electrical connection receiving parts 221 are used to realize a compound function, one end of which is used as a corner or edge piece of a building block, and also as an exposed electrode part of the building block, and is also used to receive one or more magnetic suction members 30, and cooperates with the housing 210 to limit the magnetic suction members 30.

[0046] Figure 6 This is a perspective view of the electrical connection receiving component in this embodiment. Figure 7 This is a perspective view of the electrical connection housing component from another angle in this embodiment.

[0047] like Figure 6 and Figure 7 As shown, the electrical connection receiving component 221 is a one-piece electrical connection receiving component with a certain rigidity. One end of it is box-shaped, and the rest is generally a thin rod extending from the box-shaped end. The electrical connection receiving component 221 includes an integrally formed receiving electrode part 2211, a fitting part 2212, an extension part 2213, a contact part 2214, and a conductive part 2215.

[0048] The electrode receiving part 2211 is a box-shaped structure with one open end. In this embodiment, it is a shallow trapezoidal box shape, corresponding to the corner block shape of the triangular pyramidal bipartite shell 210, and matching the positioning notch at the corner of the bipartite shell 210, allowing it to be fitted and fixed at the positioning notch. The outer surface of the electrode receiving part 2211 includes three interconnected electrode contact surfaces 22111, which are used to contact the electrode contact surfaces of other functional building blocks to achieve conductive communication. One of the electrode contact surfaces 22111 is approximately square and has a large area, serving as the main electrode contact surface. The three electrode contact surfaces 22111 correspond to the three outer surfaces of the triangular pyramidal bipartite shell 210, respectively. The electrode contact surface 22111 can be approximately flush with or slightly protruding beyond the corresponding outer surface of the bipartite shell 210. Preferably, the electrode contact surface 22111 slightly protrudes beyond the corresponding outer surface. Furthermore, the multiple electrode contact surfaces 22111 corresponding to the same outer surface of the split shell 210 are substantially coplanar, for example, the electrode contact surfaces 22111 corresponding to the four electrode portions of the square bottom surface are substantially coplanar.

[0049] The fitting portion 2212 extends from one side of the opening end of the receiving electrode portion 2211. The fitting portion 2212 has a corner-shaped groove 2216, that is, a right-angled V-shaped groove. The depth direction of the groove is consistent with the opening direction of the receiving electrode portion 2211.

[0050] The extension 2213 extends from the end of the fitting portion 2212 away from the receiving electrode portion 2211, and is in the shape of a flat and long rod. The end that connects to the fitting portion 2212 is in the shape of a Y-shape that matches the end of the fitting portion 2212, and the other end is in the shape of a semi-circular plate.

[0051] The contact portion 2214 protrudes from one end of the extension portion 2213, which is in the shape of a semi-circular plate, and is located on the same side of the extension portion 2213 as the fitting portion 2212, and its protruding direction is opposite to the opening direction of the receiving electrode portion 2211. The contact portion 2214 is in the shape of a flattened hemisphere and has an arc-shaped outer surface for contacting a corresponding contact on the circuit board.

[0052] The conductive portion 2215 is used to achieve a conductive connection, and it at least covers the outer surface of the contact portion 2214, the three electrode contact surfaces 22111 of the electrode receiving portion 2211, and a portion of the outer surface of the fitting portion 2212 and the extension portion 2213. In this embodiment, the interior of the electrical connection receiving component 2211 is a plastic substrate, and the conductive portion 2215 is a metal plating covering the entire outer surface of the substrate, which has good electrical conductivity.

[0053] Electronic component 222 is an electrical component, including a rectangular circuit board 2221 and one or more electrical functional devices 2222.

[0054] The circuit board 2221 is rectangular and its shape matches the shape of the positioning groove 2113 of the aforementioned device, allowing it to be fitted into it. Multiple contacts are distributed at the corners or edges of the circuit board 2221; in this embodiment, there are four, located at the four corners of the circuit board 221. Two of these are positive contacts, located at the two corners on one diagonal of the circuit board 2221, and the other two are negative contacts, located at the two corners on the other diagonal.

[0055] The electrical functional device 2222 is a light-emitting device or a sound-emitting device. In this embodiment, it is a light-emitting device, which is soldered and fixed to the middle of one side surface of the circuit board 2221. The positive and negative terminals of the light-emitting device are electrically connected to the positive and negative terminals at the corner through the corresponding circuit patterns on the circuit board 2221.

[0056] When the electrical functional device 2222 is a sound-generating device, the two-part housing 210 can also be made of an opaque material, and multiple through holes can be distributed on the housing to allow the sound to be transmitted better.

[0057] The positive and negative electrical connection receiving components 221 respectively contact the positive and negative electrical contacts, so that each positive electrode part 2211A is electrically connected to the positive electrode of each electrical functional device 2222, and each negative electrode part 2211B is electrically connected to the negative electrode of each electrical functional device 2222. Therefore, as long as one pair of positive electrode parts 2211A and negative electrode parts 2211B are connected to the circuit, all electrical functional devices 2222 in the functional building block can be powered on and work.

[0058] In this embodiment, the four electrical connection receiving components 221 have the same structure and size. Two of them are used as positive electrical connection components, with their receiving electrode portion 2211 serving as the positive electrode portion 2211A, and their contact portion 2214 used to contact the positive contact on the circuit board. The metal plating on their surfaces is gold-colored, and the material of the gold plating can be, for example, copper or a copper-zinc alloy. The other two are used as negative electrical connection components, with their receiving electrode portion 2211 serving as the negative electrode portion 2211B, and their contact portion 2214 used to contact the negative contact on the circuit board. The metal plating on their surfaces is silver-colored, and the material of the silver plating can be, for example, aluminum, zinc, or a zinc alloy.

[0059] In an alternative solution, the metal plating of the positive and negative electrical connection components can also be different colors, as long as the colors are different to make it easy for users to distinguish them.

[0060] The magnetic attractor 230 is used to achieve magnetic attraction between the single-ended functional building block 200 and other functional building blocks. Preferably, the magnetic attractor 230 is a permanent magnet. In this embodiment, the magnetic attractor 230 is a cuboid magnet, the size of which is slightly smaller than the size of the inner cavity of the electrode portion 211. It can be accommodated in the inner cavity, and the size of the inner cavity allows the magnetic attractor 230 to only translate and rotate slightly within the inner cavity, but not rotate significantly. Therefore, the correspondence between its polarity and the outer shell and the electrode contact surface will not change.

[0061] In this embodiment, the magnetic chuck 230 is magnetized along its own thickness direction, with its two ends in the thickness direction being the N pole and the S pole, respectively. The two magnetic chucks 230 on each bottom edge of the split shell 210 are installed in a complementary polarity manner; that is, in the two magnetic chucks 230 corresponding to each bottom edge, the N pole of one magnetic chuck 230 faces the apex of the triangular pyramid, and the other magnetic chuck 230 is rotated 180 degrees so that its S pole faces the apex of the triangular pyramid. The two magnetic chucks 230 corresponding to each bottom edge follow the above magnetic pole configuration rules, ensuring the symmetry of the magnetic pole distribution on each bottom edge of the single-ended functional building block 200. This layout allows the single-ended functional building block 200 to be freely and self-alignedly assembled with another functional building block with the same magnetic chuck configuration.

[0062] During assembly, multiple electrical connection receiving components 221, each containing a magnetic accommodating element 230, are first assembled at the corners of the opening end of the shaped housing 212, so that each snap-fit ​​part 2122 is embedded into the corner-shaped groove 2216 of each electrical connection receiving component 221. The integrated circuit board 2221 and electrical functional components 2222 are then embedded in the component positioning groove 2113 in the middle of the positioning housing 211, with the lower surface of the circuit board contacting the upper surfaces of the multiple positioning protrusions 2114. Then, the opening end of the shaped housing 212, which contains the multiple electrical connection receiving components 221, is pressed against the positioning housing 211, which contains the circuit board 2221, so that the positioning housing 211 fits into the opening end of the shaped housing 212. Finally, laser welding is performed between the edge of the positioning housing 211 and the corresponding edge of the shaped housing 212 to fix them together, thus sealing the two-part outer shell 210.

[0063] like Figure 2 As shown, after assembly, because the V-shaped snap-fit ​​part 2122 fits into the corner groove 2216 and the electrode receiving part 211 is engaged at the positioning notch, therefore, in the surface direction of the positioning housing 211 (i.e., Figure 2 (in the horizontal direction) and in the central axis direction of the single-ended functional building block 200 (i.e. Figure 2 In the vertical direction, the electrical connection receiving components 221 are fixed in place, preventing movement or deflection. The magnetic chuck 230 is housed within the cavity of the electrode receiving portion 2211 and is limited by the magnet limiting portion 2123, preventing significant displacement or deflection. The correspondence between the magnetic poles of the magnetic chuck 230 and the contact surfaces of each electrode remains constant. The electrode path 2221 is fitted into the device positioning groove 2113, and its four corners are each pressed down by an electrical connection receiving component 221, thus fixing the circuit board 2221 in the groove. That is, no additional fasteners are required when assembling the single-ended functional building block 200.

[0064] In addition, after assembly, multiple support bars 2115 on the edge of the positioning housing 211 abut against the support surface of the support step 2124 on the inner side of the edge of the shaped housing 212, and there is a gap between two adjacent support bars 2115, which can play a certain buffering role.

[0065] In addition, the electrical functional device 2222 (light-emitting device) is located in the middle of the surface of the circuit board 2221 facing the housing 212. It can be seen that there are no other structures between the electrical functional device 2222 and the housing 212, so the light emitted by the light-emitting device will not be blocked.

[0066] Figure 8 This is a perspective view of the multi-terminal functional building block in this embodiment. Figure 9 This is an exploded view of the multi-terminal functional building block in this embodiment.

[0067] like Figure 8 and Figure 9 As shown, the multi-ended functional building block 100 is generally columnar, but in this embodiment it is cubic, and includes a three-part outer shell 110, a three-dimensional electrical functional component 120 and multiple magnetic components 130.

[0068] The three-part outer shell 110 is in the shape of a corner-missing column, and in this embodiment it is in the shape of a corner-missing cube, which includes two end positioning shells 111 and a main body shell 112.

[0069] 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 and an electrode positioning groove at its corner, but no device positioning groove.

[0070] The main body housing 112 is a cylindrical shape with openings at both ends. In this embodiment, it is a square cylinder. The corners of the two opening ends each have a second notch, which can be combined with the corresponding first notch on the end positioning housing 111 to form a positioning notch. The corners of the opening ends also have V-shaped latching parts and magnet limiting parts. The inner cavity of the main body housing 112 has a partition plate in the middle, dividing its inner cavity into two parts. The middle of the partition plate has a device positioning hole, which is a square through hole.

[0071] The three-dimensional electrical functional component 120 includes multiple electrical connection housings 121 and electronic components 122.

[0072] The electrical connection receiving component 121 is a Z-shaped electrical connection receiving component, similar in structure to the straight-line electrical connection receiving component 221. It also has a box-shaped electrode receiving portion 1211, a fitting portion 1212 with a corner-shaped groove 1216, an extension portion 1213, a contact portion 1214, and a conductive portion covering the entire outer surface. The difference lies in that its overall shape is roughly Z-shaped, and the extension portion 1213 has two rod-shaped parts with a bend between them, allowing the electrical connection receiving component 121 to extend from the corner of the cubic shell to the center of the cube. Furthermore, the electrode receiving portion 1211 is a square box shape corresponding to the corner of the cube.

[0073] Electronic component 122 includes circuit board 1222 and electrical functional device 1222. Circuit board 1222 is a square plate shape that matches the positioning holes of the device. Electrical functional device 1222 consists of two light-emitting devices, which are soldered and fixed to the middle of the two surfaces of circuit board 1222 respectively. The four corners of the two surfaces of circuit board 1222 each have positive and negative contacts. Two corners on one diagonal of each surface have two positive contacts, and two corners on the other diagonal have two negative contacts. Furthermore, one positive contact and one negative contact are respectively on the two surfaces of one corner. The positive and negative terminals of each light-emitting device are electrically connected to the positive and negative contacts through corresponding circuit patterns on the circuit board.

[0074] The magnetic attractor 130 is also housed in the inner cavity of the electrode receiving part 1211 and is limited by the magnet limiting part at the corner of the main body housing 112, and the multiple magnetic attractors 130 also adopt a magnetic pole complementary configuration.

[0075] After assembly, the receiving electrode portions 1211 of each electrical connection receiving component 121 are fitted and fixed at the positioning notches at the corners of the three-part housing 110, and the multiple electrical connection receiving components 121 extend bently to the device positioning holes inside the three-part housing 110, pressing against 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.

[0076] like Figure 8 As shown, in this embodiment, each edge of the multi-ended functional building block 100 has a pair of electrode portions, namely a positive electrode portion 1211A and a negative electrode portion 1211B, and the positive electrode portions and negative electrode portions are arranged alternately.

[0077] Figure 10 This is a 3D view of the power supply building block in this embodiment. Figure 11 This is an exploded view of the power supply block in this embodiment.

[0078] like Figure 10 and Figure 11 As shown, the outer shell structure and electrical connection structure of the power supply block 300 are similar to the corresponding structure of the multi-ended functional block 100. 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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 in conductive contact with 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.

[0084] 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.

[0085] like Figure 10 As shown, in this embodiment, the multiple pairs of electrodes at the corner of the power supply block 300 are arranged in the same way as the multiple pairs of electrodes in the multi-terminal functional block, that is, the positive electrode and the negative electrode are arranged alternately.

[0086] Furthermore, in this embodiment, the distribution of multiple electrode portions on the splicing ends of the single-ended functional building block 200, the multi-ended functional building block 100, and the power supply building block 300 is matched. That is, each splicing end has two pairs of positive and negative electrode portions arranged diagonally, and the spacing between each pair of positive and negative electrode portions is approximately the same, and the size of the electrode contact surface of each electrode portion is also very close. Therefore, two or more of the above-mentioned functional building blocks can be freely spliced ​​together to form a building block unit. That is, the building block unit can include one or more single-ended functional building blocks 200 and one or more multi-ended functional building blocks 100 with matched splicing ends. Optionally, it can further include power supply building blocks 300 with matched splicing ends.

[0087] For example, a single-ended functional block 200 can be magnetically attached to one side of a multi-ended functional block 100, and a power supply block 300 can be magnetically attached to the other side of the multi-ended functional block 100. When attaching the blocks, ensure that the positive electrode parts of each block are in contact with each other and the negative electrode parts are in contact with each other with corresponding polarities, so as to achieve positive and negative interconnection and establish a conductive path. At this time, the electrical functional components of the three functional blocks form a complete current loop through the corresponding contacting electrode parts. After the power supply is turned on by the switch button 3225, the energy storage device 3223 can simultaneously supply power to the light-emitting device in the single-ended functional block 200 and the two light-emitting devices in the multi-ended functional block 100, and these light-emitting devices can emit light at the same time. If one of the building blocks is misassembled, resulting in a mismatched polarity (i.e., the positive electrode of that block is in contact with the negative electrode of another block), a complete current loop cannot be formed, and none of the assembled blocks will emit light. By combining the different colors of the positive and negative electrodes, users can easily identify assembly errors. Similarly, more functional building blocks can be assembled together.

[0088] Furthermore, since each positive electrode in the functional building block is electrically connected to the positive electrode of all electrical functional devices, and each negative electrode is electrically connected to the negative electrode of all electrical functional devices, as long as any positive electrode and any negative electrode of the functional building block are connected to other functional building blocks in a polarity-corresponding manner, the electrical functional components of the functional building block can be connected to the circuit, and all electrical functional devices therein can be energized to perform their electrical functions.

[0089] The role and effect of the embodiments According to the single-ended functional building block, building block unit, and building block toy provided in this embodiment, since a two-part shell including a positioning shell and a shaping shell is adopted, and a planar electrical functional component is adopted on the inner side of the positioning shell, and the shaping shell is made into a box shape with one end open, only its open end is used to cooperate with the positioning shell to form a positioning notch for positioning and fixing the exposed electrode part, so there is basically no limitation on the shape of the rest of the shaping shell. The rest of the shaping shell can be made into various shapes. The positioning shell and the planar electrical functional component adopt the same structure, thereby enabling the convenient and low-cost construction of a variety of single-ended functional building blocks with different shapes. Furthermore, since the planar electrical functional component uses an electrical connection housing with a certain rigidity as the electrode part and realizes the electrical connection between the electrode part and the electronic components inside the shell, it is not necessary to use soft wires and the number of soldered electrical contacts can be reduced. Moreover, one end of the electrical connection housing serves as a corner or edge block of the shell, as an exposed electrode, and also as a magnetic accommodator, realizing a composite function. Therefore, the electrical connection structure is more streamlined and more reliable, and it is less likely to have poor contact or disconnection. At the same time, it also makes the functional building block easier to produce and assemble, and the production cycle is shorter.

[0090] In this embodiment, the outer shell is a two-part shell, consisting of only two components: a positioning shell and a shaping shell. The receiving electrode part of the electrical connection receiving component is fitted into the positioning notch of the outer shell, while the electronic components are completely housed inside the outer shell. Furthermore, the positioning shell and the shaping shell are welded and fixed together, making it difficult for ordinary users to disassemble the shell by hand. Even if there are collisions or drops during use, the outer shell is not prone to loosening or falling off, thus avoiding the problem of children accidentally swallowing small parts and providing better safety in use.

[0091] Furthermore, since the electrical connection receiving component has a fitting part with a corner-shaped groove, the positioning housing has a corresponding notch and electrode positioning groove, and the modeling housing has a corresponding snap-fit ​​part, the electrical connection receiving component can be snapped and fixed by these two housings, so that it is positioned and fixed in multiple directions. This ensures that the exposed multiple electrode parts are accurately positioned and will not be displaced or deflected, ensuring that the electrode contact surface on the electrode part is accurately positioned, thereby ensuring that multiple functional building blocks can always be well spliced ​​together.

[0092] Furthermore, since the circuit board is embedded in the device positioning groove in the middle of the positioning housing, and the corners of the circuit board are pressed down by multiple electrical connection receiving components, the circuit board is fixed in the groove. At the same time, the electrical conductivity is achieved by the contact between one end of the electrical connection receiving component and the electrical contact at the corner of the circuit board. Therefore, this single-ended functional building block does not require wires or contacts formed by welding. As mentioned above, it also does not require additional fasteners. The overall structure is very simple and suitable for large-scale and efficient production.

[0093] Furthermore, the electrical connection housing is composed of a plastic substrate and a metal plating, thus ensuring good conductivity while possessing a certain rigidity to firmly hold the circuit board in place. The receiving electrode at one end also engages well with the positioning notch at the corner of the three-part outer shell. Moreover, it possesses a degree of elasticity, making it less susceptible to damage even from impacts such as collisions or drops during use, thereby enhancing the reliability of the electrical functional components. In addition, the plastic substrate is lightweight, resulting in a lighter overall weight for the single-ended functional building block.

[0094] Furthermore, the metal plating of the positive and negative electrical connection housing components uses different colors, but their structures are the same. This allows users to easily distinguish between the positive and negative electrode parts, and for multiple electrical connection housing components, only two standard parts need to be processed, making production more convenient.

[0095] Furthermore, each edge of the single-ended functional building block is equipped with a pair of magnetic attractors with complementary polarities. Therefore, when two multi-ended functional building blocks are spliced ​​together, the corresponding magnetic attractors are precisely aligned and generate an attraction force, automatically aligning and connecting the positive and negative electrodes of the two building blocks. In other words, physical splicing and circuit connection are completed simultaneously through magnetic attraction, realizing an intelligent interactive experience of powering on immediately after splicing, thus improving the user experience.

[0096] 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.

[0097] In the embodiments, the electrical functional device can be a light-emitting device, and the two-part shell is correspondingly transparent or semi-transparent. Since the internal structure can be seen through the two-part shell, the electrical connection is used to house the component, instead of using a mess of multiple wires, which also makes the appearance of the single-ended functional building block more aesthetically pleasing.

[0098] In this embodiment, a set of building block toys includes single-ended functional building blocks and multi-ended functional building blocks. The single-ended functional building blocks can achieve specific shapes, while the multi-ended functional building blocks can provide more freedom of assembly, making the building block toy more playable and better suited for the development of cognitive and other abilities in young children.

[0099] Furthermore, a set of building blocks also includes power-powered blocks, which are similar in shape to multi-functional building blocks and have built-in power storage devices. When the power-powered blocks are assembled with other functional building blocks, they can form a power supply circuit to power the other functional building blocks. When used as a toy, children do not need to connect the multi-functional building blocks to external batteries. They can simply assemble the power-powered blocks like other multi-functional building blocks, making it more convenient to use.

[0100] Furthermore, since the power supply block also contains a functional circuit board, with a charging interface, switch button, and function button exposed on one side of its outer shell, it is easy to charge the power supply block, turn the power on and off, and switch functions. In other words, the power supply block integrates multiple functions such as power supply, charging, and function control, making it very convenient to use.

[0101] Variation Example 1 This variation is a variation of the embodiment. In this variation, the same symbols are assigned to the same constituent elements as in the embodiment, and the corresponding descriptions are omitted.

[0102] Figure 12 This is a three-dimensional view of the single-ended functional building block in this variation.

[0103] like Figure 12 As shown, the only difference from the embodiment is the structure of the housing 212. The housing 212 in this modified example is also a triangular pyramid with one end open, but it has a larger height-to-side length ratio, that is, the functional building block is a taller and sharper triangular pyramid.

[0104] In this variation, the other structures are basically the same as in the embodiment, so they will not be described again.

[0105] Variation Example 2 This variation is a variation of the embodiment. In this variation, the same symbols are assigned to the same constituent elements as in the embodiment, and the corresponding descriptions are omitted.

[0106] Figure 13 This is a three-dimensional view of the single-ended functional building block in this variation. Figure 14 This is an exploded view of the single-ended functional building block in this variation.

[0107] like Figure 13 and Figure 14As shown, compared to the embodiment, the difference lies in that the single-ended functional block 200 of this modification is semi-cylindrical, and the housing 212 is semi-cylindrical with one open end. The open end is also square, and the corner has a second notch 2121. However, the shape of the second notch 2121 in this modification corresponds to the shape of the corner of the semi-cylindrical block, and its depth is relatively shallower. Correspondingly, the electrode receiving portion 2211 of the electrical connection receiving component 221 is generally a shallow, flat rectangular box shape.

[0108] In this variation, the other structures are basically the same as in the embodiment.

[0109] Variation Example 3 This variation is a variation of the embodiment. In this variation, the same symbols are assigned to the same constituent elements as in the embodiment, and the corresponding descriptions are omitted.

[0110] Figure 15 A three-dimensional view of the single-ended functional building block in this variation example. Figure 16 The exploded view of the single-ended functional building block in this variation.

[0111] like Figure 15 Figure 16 As shown, the difference from the embodiment is that the single-ended functional block 200 of this modified example is conical, and correspondingly, the shape of the two-part shell 210 and the structure of the planar electrical functional component 220 are also different.

[0112] The positioning housing 211 is roughly circular in shape, with four first notches 2111 evenly distributed along its edge. Each first notch 2111 is roughly rectangular. An electrode positioning groove 2112 is formed next to the first notch 2111; it is an open, single-sided right-angled groove. In the device positioning groove 2113, the upper end of the positioning protrusion 2114 is stepped.

[0113] The housing 212 is a cone shape with one end open, and four second notches 2121 are evenly distributed on the edge of the open end, which can be combined with the corresponding first notches 2111 to form positioning notches.

[0114] In the planar electrical functional component 220, the electrode receiving portion 2211 of the electrical connection receiving member 221 is flattened and has one side that is an arc-shaped surface corresponding to a cone. The fitting portion 2212 extends from one side of the electrode receiving portion 2211 and forms a step between it and the electrode receiving portion 2211. The fitting portion 2212 has a strip-shaped groove 2217, and the open end of the housing 212 has a "U"-shaped latching portion 2122 that matches the strip-shaped groove 2217.

[0115] Figure 17 This is a three-dimensional view of the multi-ended functional building block in this variation.

[0116] like Figure 17 As shown, the multi-ended functional block 100, which can form a block unit with the single-ended functional block 200, is cylindrical. In its three-part outer shell 110, the two end positioning shells 111 are roughly circular plates, and their structure is similar to that of the circular plate-shaped positioning shell 211. The main body shell 212 is cylindrical, and its electrical connection structure is similar to that of the three-dimensional electrical functional component in the embodiment.

[0117] One or more single-ended functional building blocks 200 and one or more multi-ended functional building blocks 100 of this modification can constitute a building block unit. Optionally, it may further include a power supply building block with an appearance similar to the multi-ended functional building block 100 of this modification. That is, the power supply building block is also cylindrical in shape, and the internal electronic components (power supply components) can be configured with reference to the power supply building block in the embodiment.

[0118] In this variation, the other structures are basically the same as in the embodiment.

[0119] Variation Example 4 This variation provides a building block toy. In this variation, the same symbols are assigned to the same constituent elements as in the embodiment, and the corresponding descriptions are omitted.

[0120] Figure 18 This is a three-dimensional view of the single-ended functional building block in this variation.

[0121] like Figure 18 As shown, compared to the embodiment, the difference lies in that the single-ended functional building block 200 of this modified example is also generally triangular pyramidal in shape, but the outer surface of the two-part outer shell 210 includes multiple facets. Specifically, the outer surface of the positioning shell 211 has a square facet 213, which is composed of four triangular facets with a concave center. Each of the multiple triangular outer surfaces of the shaping shell 212 has a triangular facet 214, which is composed of three triangular facets with a concave center.

[0122] Figure 19 This is a three-dimensional view of the multi-ended functional building block in this variation.

[0123] like Figure 19 As shown, similarly, the multi-ended functional block 100 of this variant is also cubic in shape, but each side of the three-part outer shell 110 has a square facet 113, which is composed of four triangular facets with a concave center.

[0124] 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.

[0125] 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.

[0126] In this variation, the other structures are basically the same as in the embodiment.

[0127] Furthermore, the various other shapes of functional building blocks shown in the above variations can also have similar facets. For example, the trapezoidal outer surface of the trapezoidal functional building block can also have trapezoidal facets, that is, it is also composed of four triangular facets, but the size and angle of each triangular facet are different accordingly. As another example, the square outer surface of the fan-shaped functional building block can also have square facets, and its curved outer surface can also have corresponding curved facets, that is, facets composed of four curved triangular facets.

[0128] Variation Example 5 This variation provides a building block toy. In this variation, the same symbols are assigned to the same constituent elements as in the embodiment, and the corresponding descriptions are omitted.

[0129] Figure 20 This is an example diagram of assembling the building block toy in this variation.

[0130] like Figure 20 As shown, in this variant, a set of building block toys 400 includes multiple building block units and powered building block blocks 300, each building block unit containing two or more functional building block blocks with matching splicing ends.

[0131] For example, a set of building block toys 400 includes a first building block unit 410, a second building block unit 420, a third building block unit 430, and a fourth building block unit 440.

[0132] The first building block unit 410 includes a conical functional building block 411 and a cylindrical functional building block 412, which are a single-ended functional building block and a multi-ended functional building block as shown in the modified example 3, respectively. Their splicing ends match each other and are both circular, and two pairs of electrode portions are correspondingly arranged on the edge of the splicing end.

[0133] The second building block unit 420 includes a short triangular pyramid functional building block 421 and multiple triangular prism functional building blocks 422. The short triangular pyramid functional building block 421 is a single-ended functional building block as shown in the embodiment. The triangular prism functional building block 422 is a multi-ended functional building block, with its two end positioning shells roughly in the shape of a triangular plate with missing corners, and its main body shell in the shape of a triangular cylinder with missing corners. The receiving electrode part of the electrical connection receiving component is shaped corresponding to the corner block of the triangular prism, and the electrical connection structure is similar to that in the embodiment. The splicing ends of the short triangular pyramid functional building block 421 and the triangular prism functional building block 422 are matched, both being square, and a pair of electrode parts at the corners of the splicing ends are correspondingly arranged.

[0134] The third building block unit 430 includes a triangular pyramidal functional building block 431 and a cubic functional building block 432. The triangular pyramidal functional building block 431 is a single-ended functional building block as shown in Variation 1, and the cubic functional building block 432 is a multi-ended functional building block as shown in the embodiment. Their splicing ends match and are both square, and the two pairs of electrode portions at the corners of the splicing ends are correspondingly arranged.

[0135] The fourth building block unit 440 includes a semi-cylindrical functional building block 441 and a cubic functional building block 432. The semi-cylindrical functional building block 441 is a single-ended functional building block as shown in the modified example 2. Its splicing ends match and are both square, and the two pairs of electrode parts at the corners of the splicing ends are correspondingly arranged.

[0136] like Figure 20 As shown, exemplarily, a set of building blocks 400 in this variation can be assembled into a castle-like structure. Three building blocks are respectively connected to three sides of the power supply block 300, thereby supplying power to these building blocks. Of course, the building blocks 400 can also be assembled into other shapes, and the power supply block can be connected at any position within them.

[0137] Furthermore, as shown in the figure, since the positive and negative electrode portions at the top and bottom ends of the cylindrical functional block 412 can also serve as a pair of electrode portions, and the distribution (spacing) of this pair of electrode portions is the same as the distribution of a pair of electrodes on the triangular prism functional block 422, the side of the cylindrical functional block 412 can also contact a ridge of the triangular prism functional block 422, so that the two pairs of electrode portions contact each other, thereby allowing the electronic components in the cylindrical functional block 412 and the conical functional block 411 to be connected to the circuit. Although this splicing method has lower stability compared to splicing using matching splicing ends (at least two pairs of electrode portions spliced ​​together, and at least two pairs of magnetic suction pieces correspondingly magnetically fixed), it provides more splicing possibilities. Similarly, a pair of electrode portions on the cylindrical functional block 412 can also contact a pair of electrode portions on the cubic functional block 432 to connect them to the circuit.

[0138] In this variation, the other structures are basically the same as in the embodiment.

[0139] In this variation, the number of functional building blocks in a set of building block toys is relatively small, and there is one power supply building block. In fact, a set of building block toys can contain any number of functional building blocks, and the number of power supply building blocks can also be multiple. The ratio of the power supply building block 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 the power supply building block to other functional building blocks can be 1:20-1:50.

[0140] The above embodiments and variations illustrate a variety of shapes that a single-ended functional building block can have. However, the shapes that a single-ended functional building block can have are not limited to these. Other desired shapes can also be made. Furthermore, based on the above embodiments or variations, only the shape of the shell needs to be changed. For example, a single-ended functional building block can also be cubic (with the shell being a cubic shape with one open end), cuboid, hemispherical, etc.

[0141] Furthermore, by changing the shape of both the positioning shell and the shaping shell, more shapes can be made. For example, a single-ended functional block can also be a triangular pyramid with a pentagonal or hexagonal base, and a multi-ended functional block can also be a pentagonal or hexagonal prism.

[0142] 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 above embodiments. Those skilled in the art should understand that the present invention is not limited to the above embodiments and modifications. 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 its spirit and scope, 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.

[0143] 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.
