Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of splicing toys, and particularly relates to a multi-terminal functional building block, a building block unit and a building toy. BACKGROUND

[0002] Traditional building toys usually contain multiple wooden or plastic building blocks that can be assembled by children into various shapes. Since the functions and playing methods of the building toys are relatively simple, the building toys have relatively limited appeal to children. In recent years, electric functional building blocks with lighting functions have appeared. The electric functional building blocks are provided with batteries, lighting electronic devices (such as lamp beads), circuit boards and wires, etc., and can be assembled in a conventional manner, for example, can be magnetically assembled, and can emit light, thereby expanding the functions and playing methods of the building toys. However, the existing electric functional building blocks still have some deficiencies, which limit their audience.

[0003] On the one hand, the electric connection structure of the existing electric functional building blocks is relatively complex and fragile, which not only leads to low production and assembly efficiency and long production cycle, but also is prone to failure during user play. During production, each lighting electronic device needs to be connected to the circuit board through a wire and fixed by welding. If electrodes are provided on the surface of the building block, the lighting electronic device also needs to be electrically connected to the corresponding electrode through a wire. Therefore, during the production and assembly process, multiple wires need to be arranged and connected in such a small space in the building block, forming a large number of electrical contacts, which is time-consuming and laborious and has low production efficiency. Moreover, during user play and storage of the electric functional building blocks, it is inevitable to have bumps and drops. The wires and electrical contacts are prone to poor contact or even disconnection due to the bumps and drops, which causes the electric functional building blocks to quickly lose their electrical functions and affects user experience. If a fixing structure is provided or formed in the shell to fix or protect the wires, or the wires are fixed in the shell by adhesion, the internal structure of the shell and the assembly process are further complicated, and subsequent inspection and maintenance are more difficult.

[0004] On the other hand, the existing electric functional building blocks are often easily disassembled. During play, the shell is prone to loosen or even disintegrate due to impact from drops, etc. The wires, lighting electronic devices, magnets, etc. in the shell are all small parts, and if children accidentally eat these small parts, it may cause harm to the body. Therefore, the electric functional building blocks also have certain safety hazards. SUMMARY

Furthermore, since one end of each electrical connection receiving component serves as an electrode housing, fitting into the positioning notch on the three-part outer shell, and also serves to house the magnetic component, it can cooperate with the positioning notch to position the magnetic component.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the multi-terminal functional building block and the building block toy of the present application are specifically described below in combination with embodiments and drawings.

[0021] Embodiment One This embodiment provides a building block toy for users to play with. It includes multiple multi-terminal functional building blocks and power supply building blocks, which can be magnetically connected and assembled together. Each multi-terminal functional building block has an electrical functional device. After being assembled, these electrical functional devices can be connected to a circuit and powered to perform their corresponding electrical functions.

[0022] Figure 1 This is a perspective view of the multi-terminal functional building block in this embodiment. Figure 2 This is an exploded view of the multi-terminal functional building block in this embodiment.

[0023] like Figure 1 and Figure 2 As shown, the multi-ended functional building block 100 is generally columnar, and in this embodiment it is cubic (i.e., square columnar). In alternative embodiments, it can also be columnar in other shapes. The multi-ended functional building block 100 includes a three-part outer shell 110, a three-dimensional electrical functional component 120 disposed on the three-part outer shell 110, and a plurality of magnetic components 130.

[0024] The three-part outer shell 110 is a columnar shape with missing corners, and in this embodiment, it is a cubic shape with missing corners. The three-part outer shell 110 is made of a lightweight and insulating material, such as plastic. The outer shell 110 includes two end positioning shells 111 and a main body shell 112. The three shells cooperate to position and fix the three-dimensional electrical functional component 120 and the magnetic accumulator 130.

[0025] The end positioning housing 111 is an integrally formed part, which includes a plate-shaped part missing four corners (i.e., a relatively wide cross-shaped plate) and L-shaped ribs protruding from each corner of one surface of the plate-shaped part. The end positioning housing 111 has multiple first notches 1111, multiple electrode positioning grooves 1112 and multiple electrode clearance grooves 1113.

[0026] The first notch 1111 is a rectangular notch, formed at each corner of the end positioning housing 111.

[0027] The electrode positioning groove 1112 is an open corner groove used as a snap-fit ​​positioning groove for the electrode part. The electrode positioning groove 1112 is formed next to each first notch 1111. Its bottom is the edge of the notch of the plate-shaped part, which is V-shaped. Its two side walls are one side surface of the L-shaped 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.

[0028] The electrode clearance groove 1113 is a rectangular groove formed at the bend of the L-shaped rib, used to make way for the placement of the three-dimensional electrical functional component 120.

[0029] Figure 3This is a perspective view of the main body shell in this embodiment.

[0030] like Figure 3 As shown, the main body shell 112 includes an integrally formed main body part 1121, a partition 1122, multiple guide and positioning parts 1123, and multiple magnet limiting parts 1124.

[0031] The main body 1121 is roughly in the shape of a hollow square column with missing corners, has four edges, and is open at both ends in the height direction, with notches forming at each corner.

[0032] The partition 1122 is sheet-shaped and formed in the middle of the height direction of the main body 1121, perpendicular to that height direction. A square hole, which is a component positioning hole 1126, is formed in the middle of the partition 1122 and extends along the height direction of the main body 1121. The directions of each side of the component positioning hole 1126 are parallel to the directions of each side surface of the main body 1121.

[0033] Multiple guide positioning portions 1123 are formed on the inner side of each edge of the positioning portion body 1121 and protrude toward the center of the shaping main body 1121. The guide positioning portion 1123 is strip-shaped, with an L-shaped cross-section in its length direction, and its length direction is consistent with the height direction of the shaping main body 1121. The protruding edge in its middle points toward the center of the shaping main body 1121. The end of the guide positioning portion 123 in its length direction is located further outward than the corner of the supporting body 1121, forming a positioning end 11231 protruding outward. The positioning end 11231 is V-shaped, that is, it includes two perpendicular plate-shaped portions, which are perpendicular or parallel to each side of the shaping main body 1121.

[0034] A rectangular groove is formed between each corner of the main body 1121 and the outer side (i.e., its inner corner) of the guide and positioning part 1123. The magnet limiting part 1124 is rectangular and is disposed in the rectangular groove. In the height direction of the main body 1121, the first outer end face 11241 of the magnet limiting part 1124 is approximately flush with the second outer end face 1211 of the corner of the main body 1121.

[0035] The side shape of the end positioning shell 111 matches the shape of the two ends of the height direction of the main body molding shell 112, and can be embedded with each other. When the two end positioning shells 111 are respectively embedded and fixed on the two ends of the main body molding shell 112, the first notch and the corresponding second notch are combined into a positioning notch, that is, a positioning notch is formed between the side of the end positioning shell 111 and the corresponding end of the guide positioning part 1123 supporting each corner of the main body 1121. Each positioning notch is a cuboid notch, which has a supporting bottom surface, two supporting side surfaces and a supporting top surface. The supporting bottom surface includes the outer end surface of the corner of the molding main body part 1121 and the outer end surface of the magnet limiting part 124. The two supporting side surfaces are the two surfaces of the corresponding inside corners of the guide positioning part 1123. The supporting top surface is the inside surface of the corresponding corner of the end positioning shell 111.

[0036] When the two end positioning shells 111 are respectively embedded and fixed on the two ends of the main body molding shell 112, a relatively closed inner cavity is formed in the three-part shell 110, and the partition plate 1122 divides the inner cavity into two inner cavity parts 110A of the same volume along the height direction of the molding main body part 1121. The two inner cavity parts 110A are only communicated through the device positioning hole 1126.

[0037] As shown in Figure 2 The three-dimensional electric functional assembly 120 includes a plurality of electric connection containing parts 121 and an electric component 122 (electronic component). In this embodiment, there are eight electric connection containing parts 121.

[0038] Each electric connection containing part 121 is used to realize a composite function: one end is used as a corner block or an edge block of the multi-terminal functional building block 100, which is a cube corner block in this embodiment, and is also used to contain one or more magnetic attraction members 130. The whole is used to realize the electrical connection between the electric component 122 and the exposed electrode of the multi-terminal functional building block 100, so that when two multi-terminal functional building blocks 100 are spliced, the electric components 122 of the two multi-terminal functional building blocks 100 can realize electrical connection through the corresponding mutual contact of their electrodes.

[0039] Figure 4 is a perspective view of the electric connection containing part in this embodiment, Figure 5 is a perspective view of the electric connection containing part in another angle in this embodiment.

[0040] As shown in Figure 4 and Figure 5As shown, the electrical connection accommodating member 121 is an integral member with certain rigidity, which is substantially in the shape of a square box at one end and a thin rod at the other end. The electrical connection accommodating member 121 includes an accommodating electrode portion 1211, an engaging portion 1212, an extending portion 1213, a contact portion 1214 and a conductive portion 1215, which are integrally formed.

[0041] The accommodating electrode portion 1211 is in the shape of an open box, which is substantially in the shape of a rectangular box in this embodiment, and is capable of being engaged and fixed at the positioning notch as a corner block, since its shape matches that of the positioning notch on the three-part outer shell 110. The outer surface of the accommodating electrode portion 1211 includes three electrode contact surfaces 12111 (i.e. the top surface and two side surfaces of the accommodating electrode portion 1211) for contacting the electrode contact surfaces of other multi-terminal functional building blocks 100. The three electrode contact surfaces 12111 correspond to the three outer side surfaces of the three-part outer shell 110, respectively, and can be substantially flush with or slightly protrude from the corresponding outer side surfaces of the three-part outer shell 110. The open end and the inner cavity of the accommodating electrode portion 1211 are used for placing the magnetic member 130. Preferably, the edges and corners of the accommodating electrode portion 1211 are rounded or chamfered.

[0042] The engaging portion 1212 extends from the other two side surfaces of the accommodating electrode portion 1211 and is close to the open end of the accommodating electrode portion 1211, so that a stepped structure is formed between the accommodating electrode portion 1211 and the engaging portion 1212. The engaging portion 1212 is in the shape of a bent sheet, which includes a V-shaped sheet portion parallel to the top surface of the accommodating electrode portion 1211 and a V-shaped sheet portion perpendicular thereto. The top surface of the V-shaped sheet portion parallel to the top surface is an abutting surface 2121, which is a V-shaped plane. A V-shaped corner-type engaging groove 1216 is formed between the engaging portion 1212 and the other two side surfaces of the accommodating electrode portion 1211, and the corner-type engaging groove 1216 matches the positioning end 11231 (the buckle portion) of the corner of the main modeling shell 112.

[0043] The extension 1213 extends from the outer end of the fitting part 1212, and includes a first extension part 12131 and a second extension part 12132 connected in sequence. The first extension part 12131 is in the shape of a rod as a whole, and the cross section in the length direction is in the shape of a V, and the included angle between the extension direction and the top surface of the accommodating electrode part 1211 is an obtuse angle close to a right angle, i.e. the first extension part 12131 is slightly outwardly inclined. The first extension part 12131 is formed with a guide groove 12133 on the side toward the opening end of the accommodating electrode part 1211, and the guide groove 12133 extends along the length direction of the first extension part 12131, and the shape thereof matches the shape of the guide positioning part 1123. The second extension part 12132 extends from the outer end of the first extension part 12131 along one diagonal direction of the top surface of the accommodating electrode part 1211, i.e. the extension direction is substantially parallel to the top surface of the accommodating electrode part 1211. The second extension part 12132 is in the shape of an oblong rod, and the outer end thereof is in the shape of a semicircular plate.

[0044] The contact part 1214 extends from the outer end of the second extension part 12132, and extends from the side surface of the second extension part 12132 farther away from the accommodating electrode part 1211, and is in the shape of a flat semisphere, and has an arc-shaped outer surface for contacting the contacts on the circuit board 1221.

[0045] The conductive part 1215 is used for realizing conductive connection, and covers at least the outer surface of the contact part 1214, the three electrode contact surfaces 12111 of the accommodating electrode part 1211, the fitting part 1212 and part of the outer surface of the extension part 1213. In this embodiment, the inside of the electrically connecting accommodating part 21 is a plastic piece, and the conductive part 1215 is the entire outer surface of the electrically connecting accommodating part 121, which is a metal plating layer with good conductive performance covering the entire outer surface of the plastic piece.

[0046] The electrically used part 122 includes a circuit board 1221 and one or more electrically functional devices 1222.

[0047] The circuit board 1221 is in the shape of a square plate matching the device positioning hole 1126, and can be substantially fitted in the device positioning hole 1126. The corners or edge portions of the circuit board 1221 are respectively provided with a plurality of contacts, eight in this embodiment, which are respectively located at the corners of the two surfaces of the circuit board 1221, wherein the two contacts on one diagonal line of one surface of the circuit board 1221 are two positive contacts, and the two contacts on the other diagonal line are negative contacts; the contacts on the other surface are staggered with the contacts on the surface, i.e. in the thickness direction of the circuit board 1221, the two surfaces of each corner are respectively provided with a positive contact and a negative contact. Each contact is in the shape of an arc-bottom groove matching the contact part 1214.

[0048] In this embodiment, the eight electric connection accommodating components 121 are of the same structure and size. Four of them are used as the positive electric connection accommodating components 121, which accommodate the electrode part 1211 as the positive electrode part 1211A, and the contact part 1214 contacts the positive contact 1221A, and the metal coating on the outer surface is gold, and the material of the gold coating may, for example, be copper or copper-zinc alloy; the other four are used as the negative electric connection accommodating components 121, which accommodate the electrode part 1211 as the negative electrode part 1211B, and the contact part 1214 contacts the negative contact 1221B, and the metal coating on the outer surface is silver, and the material of the silver coating may, for example, be aluminum, zinc or zinc alloy. In an alternative, the metal coating of the positive electric connection accommodating components and the negative electric connection accommodating components may also be of different colors, as long as the colors of the two are different, so that the user can easily distinguish them.

[0049] Corresponding to the distribution of the contacts on the circuit board 1221, two positive electrode parts 1211A are arranged on one diagonal line of one end of the multi-terminal functional building block 100, and two negative electrode parts 1211B are arranged on the other diagonal line; the electrode parts of the other end of the multi-terminal functional building block 100 are also arranged in the same diagonal line distribution, and are staggered with the electrode parts of the above-mentioned one end, that is, one positive electrode part 1211A and one negative electrode part 1211B are arranged corresponding to each edge of the main modeling shell 112. The six ends of the multi-terminal functional building block 100 can all be used as splicing ends.

[0050] The electric functional device 1222 may be one or more, which may be one or more light-emitting devices, one or more sound-emitting devices, or a combination thereof. In this embodiment, it is two light-emitting devices, specifically LED lamp beads, which are fixed in the middle of the two surfaces of the circuit board 1221, and the positive electrode is electrically connected to the plurality of positive contacts through the circuit pattern on the circuit board 1221, and the negative electrode is electrically connected to the plurality of negative contacts through the circuit pattern on the circuit board 1221.

[0051] Since the electric functional device 1222 of this embodiment is a light-emitting device, the three-piece shell 110 is preferably made of transparent or translucent material, such as transparent or translucent plastic or acrylic material, so that the light generated by the light-emitting device can better pass through. When the electric functional device 1222 is a sound-emitting device, the three-piece shell 110 can also be made of opaque material, and a plurality of through holes can be formed on the shell to better transmit the sound generated by the sound-emitting device.

[0052] The magnetic attraction member 130 is used to realize the magnetic attraction between the multi-terminal functional building block 100 and other multi-terminal functional building blocks 100. Preferably, the magnetic attraction member 130 is a permanent magnet. In this embodiment, the magnetic attraction member 130 is a cuboid-shaped magnet that matches the shape of the inner cavity of the electrode accommodating portion 1211. The size of the magnetic attraction member 130 is slightly smaller than the size of the inner cavity of the electrode accommodating portion 1211, and the magnetic attraction member 130 can be accommodated in the inner cavity. The electrode accommodating portion 1211 cooperates with the corresponding positioning gap to limit the magnetic attraction member 130. After assembly, the upper end of the magnet limiting portion 1124 is located at the opening of the electrode accommodating portion 1211, which semi-closes the opening in the diagonal direction, so that the magnetic attraction member 130 cannot fall out.

[0053] In this embodiment, the magnetic attraction member 130 is a cuboid-shaped magnet that corresponds to the shape of the inner cavity of the electrode accommodating portion 1211. The size of the magnetic attraction member 130 is smaller than the size of the inner cavity, but the length, width and height of the magnetic attraction member 130 are at least 2 / 3 of the length, width and height of the inner cavity, respectively. Therefore, the magnetic attraction member 130 can slightly translate and rotate in the inner cavity, but cannot rotate greatly, so that the corresponding relationship of the polarity will not change. The magnetic attraction member 130 is magnetized along its thickness direction, and the two ends of the thickness direction are N and S poles, respectively. The two magnetic attraction members 130 at the two ends of each edge of the three-part shell 110 are installed in a complementary polarity manner, that is, among the two magnetic attraction members 130 corresponding to each edge, the N pole of one magnetic attraction member 130 faces the end positioning shell, and the other magnetic attraction member 130 is rotated by 180 degrees, so that its S pole faces the end positioning shell. The two magnetic attraction members 130 corresponding to each edge all follow the above-mentioned magnetic pole configuration rule, which ensures the symmetry of the magnetic pole distribution of each edge of the multi-terminal functional building block 100. This layout allows two multi-terminal functional building blocks 100 to be freely assembled.

[0054] In the assembly, the main body shell 112 can be first placed on a flat surface with its upper end and lower end as open ends, and a magnetic member 130 is placed at each of the notches on the upper end, and then two positive electrode connection accommodating members 121 and two negative electrode connection accommodating members 121 are placed on the upper side of the partition 1122 in the main body shell 112. Specifically, the guide slot 12133 of each electrode connection accommodating member 121 is roughly aligned with a guide positioning portion 1123 and is placed downward, and during the downward movement of the electrode connection accommodating member 121, the ridge tip of the guide positioning portion 1123 is inserted into the guide slot 12133 to play a guiding role. The electrode connection accommodating member 121 is continuously pressed downward until the groove 1216 is fitted on the positioning end 11231 of the guide positioning portion 1123, at which time the accommodating electrode portion 1211 is fitted in the notch on one end of the main body shell 112, the contact portion 1214 is located at the device positioning hole 1126, and the magnetic member 130 is placed in the inner cavity of the accommodating electrode portion 1211. After the four electrode connection accommodating members 121 are assembled as above, an end positioning shell 111 is fitted on the one end of the main body shell 112, the accommodating electrode portion 1211 is fitted in the corresponding positioning notch, and the positioning end 11231 of the corner portion of the main body shell 112 is fitted in the corner-shaped groove 1216 of the electrode connection accommodating member 121, and the side of the accommodating electrode portion 1211 and the side of the fitting portion 1212 (both sides of the step) are clamped in the electrode positioning groove 1112, so as to accurately position the accommodating electrode portion 1211 on the three-part shell 10. As described above, the three electrode contact surfaces 2111 of the accommodating electrode portion 1211 correspond to the three outer surfaces of the three-part shell 10, and slightly protrude outward relative to the corresponding outer surfaces.

[0055] Then, the main body shell 112 with the four electrode connection accommodating members 121 and the end positioning shell 111 is inverted, the device positioning hole 1126 in the middle of the partition 1122 is placed in the electrical component 122, and then another four electrode connection accommodating members 121 are installed above the partition 1122, and another end positioning shell 111 is installed on the other end of the main body shell 112, so as to complete the assembly.

[0056] After the assembly is completed, each electrode accommodating part 1211 (i.e. each positive or negative electrode part) is respectively embedded and fixed in each positioning gap, and its position relative to the three-part shell 110 is accurately positioned; the electrical component 122 is embedded in the device positioning hole 1126 in the middle of the three-part shell 110, and the two surfaces of each corner of the electrical component 122 are respectively in contact with the contact part 1214 of one electrical connection accommodating part 121, so that each positive electrode part and each negative electrode part are respectively in conduction with the positive and negative electrodes of the electrical functional device 1222. And, through the contact between the contact part 1214 of the plurality of electrical connection accommodating parts 121 and the corner of the electrical component 122, the electrical component 122 is also fixed. The electrical conduction and the fixation of the electrical component can be achieved without welding.

[0057] Optionally, after the assembly is completed, laser welding can be performed between the edges of the two end positioning shells 111 and the corresponding edges of the main body modeling shell 112, so as to firmly fix them.

[0058] When the outer surfaces of the two above-mentioned multi-terminal functional building blocks 100 are close to each other, the four magnetic attraction members 130 of the four corners corresponding to the outer surfaces make the two multi-terminal functional building blocks 100 magnetically attract and combine, at the same time, the corresponding positive electrode contact surfaces on the outer surfaces of the two multi-terminal functional building blocks 100 are in contact with each other, realizing the interconnection of the positive electrodes, and the corresponding negative electrode contact surfaces are also in contact with each other, realizing the interconnection of the negative electrodes, so as to establish an electrical conduction path. After one of the multi-terminal functional building blocks 100 is connected to a power source, a complete current loop is formed, and the electrical functional devices 1222 in the two multi-terminal functional building blocks 100 are both powered on. Similarly, more functional building blocks can be spliced. If one of the functional building blocks is spliced incorrectly, the polarities do not correspond (i.e. the positive electrode part of the functional building block is in contact with the negative electrode part of another functional building block), a complete current loop cannot be formed, and the spliced functional building blocks will not emit light. By combining the positive electrode parts and the negative electrode parts of different colors, the user can easily find the splicing error.

[0059] And, since each positive electrode part 1211A of the multi-terminal functional building block 100 is electrically connected to the positive electrodes of all the electrical functional devices 1222, and each negative electrode part 1211B is electrically connected to the negative electrodes of all the electrical functional devices 1222, as long as the electrode contact surface of one positive electrode part and the electrode contact surface of one negative electrode part of the multi-terminal functional building block 100 are in contact with the electrode contact surfaces of the positive electrode parts and the negative electrode parts of other multi-terminal functional building blocks 100 in a polarity corresponding manner, all the electrical functional devices 1222 in the multi-terminal functional building block 100 can be powered on.

[0060] Effects of the embodiment The multi-terminal functional building block and the building block toy provided by the embodiment have a three-part shell and an electrical functional assembly arranged on the three-part shell, and the electrical functional assembly comprises an electrical component and a plurality of electrical connection accommodating components, one end of each electrical connection accommodating component is an electrode portion, is fitted in a positioning notch on the three-part shell, and extends to the electrical component in the three-part shell, so that the one end of the electrical connection accommodating component can be used as an electrode in contact with other multi-terminal functional building blocks, and the electrical connection between the electrode and the electrical component in the three-part shell is realized through the relatively rigid electrical connection accommodating component, so that the number of electrical contacts can be reduced without using soft wires, and the electrical connection structure in the three-part shell is more simplified and reliable, and is not prone to poor contact or even disconnection, and is easier to produce and assemble with a shorter production cycle. Further, one end of each electrical connection accommodating component is an electrode accommodating portion fitted in the positioning notch on the three-part shell, and is also used to accommodate a magnetic member, and the magnetic member is positioned in cooperation with the positioning notch, so that the positions of the plurality of electrodes and the plurality of magnetic members of the multi-terminal functional building block can be accurately positioned during use, so that the plurality of multi-terminal functional building blocks can be conveniently spliced at all times, and electrical connection is realized during splicing. In addition, multiple functions are realized by a single component, thereby reducing the number of overall components and making the structure of the multi-terminal functional building block more simplified and easier to produce and assemble.

[0061] In the embodiment, the three-part shell is composed of a cylindrical main body modeling shell and two end positioning shells, the electrode accommodating portion of the electrical connection accommodating component is fitted and fixed in the positioning notch of the three-part shell, the electronic component is completely accommodated in the three-part shell, and the end positioning shell and the main body modeling shell are welded and fixed, so that a general user cannot disassemble the three-part shell by hand, and even if there is a collision or a fall during use, the three-part shell is not prone to looseness, thereby avoiding the problem of children mistakenly swallowing small components and having better use safety.

[0062] Further, each electrical connection accommodating component has a Z-shaped overall structure, the other end has a contact portion that can be in contact with a contact on a circuit board of an electrical device to realize electrical conduction and press and fix the circuit board, and the electrode accommodating portion is fitted and fixed in the positioning notch, so that the multi-terminal functional building block does not need wires, does not need to form contacts by welding, and does not need additional fixing members, and the overall structure is very simplified and suitable for large-scale and efficient production.

[0063] Further, since the electrical connection accommodating component also has an embedding part, a V-shaped embedding groove is formed between the accommodating electrode part and the embedding part, and the corner of the main body modeling shell has a corresponding shaped positioning end, so that when assembling, the positioning end is embedded in the embedding groove, which can ensure that the accommodating electrode part is located at the correct position on the three-piece shell, further improving the assembly efficiency and the position accuracy of the positive and negative electrode parts.

[0064] Further, since the electrical connection accommodating component also has an extension part, and a guide groove is formed on one side of the extension part, the inner side of the edge of the main body modeling shell has a guide positioning part matched with the guide groove, so that through the cooperation of the two, each electrical connection accommodating component is conveniently and quickly assembled in place, further improving the assembly efficiency.

[0065] Further, the electrical connection accommodating component is composed of a plastic base and a metal plating layer, so that it has a certain rigidity while ensuring good electrical conductivity, and can well press the electrical component in the middle part, and the accommodating electrode part at one end can also be well clamped in the positioning gap of the corner of the three-piece shell, and it also has a certain elasticity, so that the electrical connection accommodating component is not easily damaged even if it is impacted, dropped or other impacts during use, thereby making the electrical function assembly have better reliability. In addition, the plastic base is very light in weight, so such a structure also makes the overall weight of the multi-terminal type function building block lighter.

[0066] Further, the metal plating layers of the positive and negative electrical connection accommodating components are of different colors, and their structures are the same, which can make it easy for users to distinguish the positive electrode part and the negative electrode part, and for multiple electrical connection accommodating components, only two standard parts need to be processed, making production more convenient.

[0067] Further, each edge of the multi-terminal type function building block is provided with a pair of magnetic attraction pieces with complementary polarities, so that when two multi-terminal type function building blocks are spliced, the corresponding magnetic attraction pieces are accurately positioned to generate an attractive force, automatically aligning the positive and negative electrode parts of the two building blocks for contact and conduction. That is, physical splicing and circuit conduction are simultaneously completed through magnetic attraction, realizing intelligent interaction experience of splicing and power-on, making the user's experience better.

[0068] Further, since the shape of the magnetic attraction piece matches the shape of the inner cavity of the accommodating electrode part, and its size is slightly smaller than the size of the inner cavity, and the accommodating electrode part cooperates with the positioning gap to accommodate and limit the magnetic attraction piece, the magnetic attraction piece is easy to assemble, and after assembly, the corresponding relationship of the polarity of the magnetic attraction piece can be maintained at all times, thereby ensuring the user's long-term use experience.

[0069] In the embodiment, the electrical functional device can be a light-emitting device, and the three-part shell is correspondingly transparent or semi-transparent. Since the internal structure can be seen through the three-part shell, the electrical connection is used to house the component, instead of using a bunch of messy wires, which also makes the appearance of the multi-ended functional building block more aesthetically pleasing.

[0070] Example 2 This embodiment provides a multi-functional building block 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.

[0071] Figure 7 This is a perspective view of the multi-terminal functional building block in this embodiment. Figure 8 This is an exploded view of the multi-terminal functional building block in this embodiment.

[0072] like Figure 7 and Figure 8 As shown, the difference from Embodiment 1 is that the multi-terminal functional building block 100 in this embodiment is used as a power supply building block, and it also includes a three-part outer shell 110 and a three-dimensional electrical functional component 120.

[0073] The three-part outer shell 110 includes two end positioning shells 111 and a main body shell 112. One end positioning shell 111 has the same structure as in the embodiment, while the other end positioning shell 111 serves as a functional shell. This functional shell has two through circular clearance holes 1113 in its middle and a through strip-shaped clearance hole 1114 on one side edge. Furthermore, the functional shell has at least one pair of columnar protrusions 1115 on the ribbed side surface, with mounting holes formed in the middle of the columnar protrusions 1115.

[0074] The three-dimensional electrical functional component 120 includes multiple electrical connection receiving parts 121 and a power supply part 123 (electronic part). The structure of the electrical connection receiving parts 121 is the same as in the embodiment.

[0075] The power supply component 123 includes a connection circuit board 1231, an energy storage device 1232, a function circuit board 1233, a charging interface 1234, a switch button 1235, and a function button 1236.

[0076] The connecting circuit board 1231 is square in shape and its shape matches the device positioning hole 1126. It is roughly fitted into the device positioning hole 1126, and each of its two corner surfaces has a contact point, which contacts the eight electrical connection receiving parts 121 to achieve electrical connection.

[0077] The power storage device 1232, for example, is a battery in a cuboid shape, is housed in one of the inner cavity portions 110A, and is substantially sandwiched by the first extension portions 12131 of the four electrical connection housing members 121 in the inner cavity portion 110A, with the lengthwise ends thereof substantially in contact with the inner surface of the main body molding case 112, so that the power storage device 1232 is substantially fixed in the inner cavity portion 110A.

[0078] The functional circuit board 1233 is in a cross-shaped plate shape, is disposed in the other inner cavity portion 110A, and is disposed close to the functional end positioning case 111, the edge portion of the functional circuit board 1233 has one or more pairs of fixing holes, which are distributed in correspondence with the distribution of the columnar protrusions 1115, so that the functional circuit board 1233 can be fixed to the functional end positioning case 111 by fixing members.

[0079] The charging interface 1234 is disposed on the functional circuit board 1233 and is exposed outwardly through the strip-shaped clearance hole 1114, and the power storage device 1232 can be charged through the charging interface 1234. In this embodiment, it is a standard Type-C interface.

[0080] The switch button 1235 and the function button 1236 are both circular buttons, are respectively disposed on the functional circuit board 1233, and are respectively exposed outwardly through two circular clearance holes 1113, and can be pressed by a user, the power supply of the power storage device 1232 can be controlled by the switch button 1235 to be started or stopped, and the corresponding functions can be realized by the function button 1236, for example, the supply voltage of the power storage device 1232 is switched, so as to control the luminous brightness of the light-emitting device in other multi-terminal functional building blocks 100 that are spliced with the multi-terminal functional building block 100.

[0081] The connection circuit board 1231 is electrically connected to the power storage device 1232 and the functional circuit board 1233 through wires. The power storage device 1232 is electrically connected to the plurality of positive electrode portions and the plurality of negative electrode portions through wires and corresponding circuit patterns on the connection circuit board 1231.

[0082] In assembly, the plurality of electrical connection housing members 121, the plurality of magnetic members 130, and the connection circuit board 1231 can be assembled to the main body molding case 112 according to the method of the embodiment. After the electrical connection housing members 121 are installed, the power storage device 1232 is placed in one of the inner cavity portions 110A, and the upper end positioning case 111 is installed. The functional circuit board 1233, the charging interface 1234, the switch button 1235, and the function button 1236 can be pre-made into an integrated component, the integrated component is first fixed to the functional end positioning case 111 (i.e., the end positioning case with a through hole), and then the end positioning case 111 and the integrated component are integrally assembled to the other end of the main body molding case 112.

[0083] After the assembly is completed, the multi-terminal functional building block 100 of the embodiment has substantially the same overall appearance as that of the first embodiment, and the difference is only that a charging interface and a button are exposed on one surface thereof. The multi-terminal functional building block 100 of the embodiment can be connected with the multi-terminal functional building block 100 of the first embodiment to supply power to the functional building blocks that consume power.

[0084] The building toy can include at least one multi-terminal functional building block 100 (power supply building block) of the embodiment and a plurality of multi-terminal functional building blocks 100 (power consumption building blocks) of the first embodiment. The building toy can also include a plurality of power supply building blocks, and the number ratio of the power supply building blocks to the power consumption building blocks is preferably 1:20-1:50, depending on the parameters of the power storage device 1232, the parameters of each electrical functional device 1222, the configuration and parameters of the circuit board 1221, and the configuration and parameters of the connection circuit board 1231, etc.

[0085] Effects of the second embodiment According to the multi-terminal functional building block and the building toy provided by the embodiment, on the basis of the effects of the first embodiment, since the power storage device and the connection circuit board are arranged in the three-part shell, the positive and negative poles of the power storage device are electrically connected to the respective positive and negative electrode portions, and therefore the multi-terminal functional building block as a power supply building block can form a power supply circuit when connected with other multi-terminal functional building blocks that consume power, thereby supplying power to other building blocks. When used as a toy, children do not need to connect the multi-terminal functional building block to an external battery when playing, but only need to connect the power supply building block like other multi-terminal functional building blocks, which is more convenient to use.

[0086] Further, since the functional circuit board is also arranged in the three-part shell, the charging interface, the switch button, and the function button are exposed on one side surface of the three-part shell, and therefore the power supply building block can be conveniently charged, the power supply can be turned on and off, and the function switching can be realized, i.e., the power supply building block integrates multiple functions such as power supply, charging, and function control, which is very convenient to use.

[0087] First variant This variant is a variant of the first embodiment, and the same reference numerals are assigned to the same constituent elements as those of the first embodiment, and the corresponding description is omitted.

[0088] Compared with the first embodiment, the difference is that the multi-terminal functional building block 100 of the variant is a cuboid column, and accordingly, the height-width ratio of the main body modeling shell 12 is larger than that of the first embodiment, and the length ratio of the first extension portion 2131 to the second extension portion 2132 of each electrical connection accommodating member 21 is also larger than that of the first embodiment.

[0089] In this modified example, the other structures are basically the same as in Example 1.

[0090] Variation Example 2 This variation is a modification of Embodiment 1. In this variation, the same symbols are assigned to the same constituent elements as in Embodiment 1, and the corresponding descriptions are omitted.

[0091] Figure 9 This is a three-dimensional view of the multi-ended functional building block in this variation example. Figure 10 This is an exploded view of the multi-ended functional building block in this variation.

[0092] like Figure 9 and Figure 10 As shown, compared with Embodiment 1, the difference is that the multi-ended functional building block 100 in this modified example is generally triangular prism-shaped. Correspondingly, the end positioning housing 111 is roughly triangular plate with missing corners, the main body housing 112 is hollow triangular cylinder, the device positioning hole 1126 in the middle of the main body housing 112 is a triangular through hole, and the circuit board 1221 is a matching triangular plate.

[0093] There are six electrical connection receiving components 121. The receiving electrode portion 1211 of each electrical connection receiving component 121 is shaped to correspond to the corner block of a triangular prism. The distribution of the multiple electrode portions is as follows: each edge of the main body housing 112 has one positive electrode portion 1211A and one negative electrode portion 1211B at each end; the multi-end type functional building block 100 has one positive electrode portion 1211A and two negative electrode portions 1211B at one end (i.e., at a triangular end face) in the height direction, and two positive electrode portions 1211A and one negative electrode portion 1211B at the other end.

[0094] In this modified example, the other structures are basically the same as in Example 1.

[0095] In this modified example, the multi-ended functional block 100 is generally in the shape of an equilateral triangular prism. In an alternative embodiment, it can also be in the shape of a right triangular prism, and one edge of the main body shell 12 may not have an electrode portion. Alternatively, the multi-ended functional block 100 can also be in the shape of other convex polygonal prisms, such as pentagonal prisms, hexagonal prisms, etc.

[0096] Variation Example 3 This variation is a modification of Embodiment 1. In this variation, the same symbols are assigned to the same constituent elements as in Embodiment 1, and the corresponding descriptions are omitted.

[0097] Figure 11 This is a three-dimensional view of the multi-ended functional building block in this variation example. Figure 12 This is an exploded view of the multi-ended functional building block in this variation.

[0098] like Figure 11 and Figure 12 As shown, compared with Embodiment 1, the difference lies in that the multi-ended functional building block 100 in this variant is generally trapezoidal columnar. Correspondingly, the end positioning housing 111 is roughly trapezoidal plate with a missing corner, and the main body housing 112 is trapezoidal columnar. The device positioning hole 1126 in the middle of the main body housing 112 is a triangular through hole, and the circuit board 1221 is a matching triangular plate.

[0099] There are six electrical connection receiving components 121. Four of these electrical connection receiving components 121 are respectively located at the four corners (obtuse angles of the trapezoid) of the multi-ended functional building block 100, and the receiving electrode portions 1211 of these four electrical connection receiving components 121 are corner block shapes corresponding to the corners of the multi-ended functional building block 100. The other two electrical connection receiving components 121 are respectively located at the middle of the two edges of the multi-ended functional building block 100 (middle of the base of the trapezoid), and the receiving electrode portions 1211 of these two electrical connection receiving components 121 are approximately cubic box shapes. That is, this modified example shows the shape of the electrode portions provided on the edges of the three-part outer shell 10.

[0100] In this modified example, the other structures are basically the same as in Example 1.

[0101] Variation Example 4 This variation is a modification of Embodiment 1. In this variation, the same symbols are assigned to the same constituent elements as in Embodiment 1, and the corresponding descriptions are omitted.

[0102] Figure 13 This is a three-dimensional view of the multi-ended functional building block in this variation example. Figure 14 This is an exploded view of the multi-ended functional building block in this variation.

[0103] like Figure 13 and Figure 14 As shown, compared with Embodiment 1, the difference is that the multi-ended functional building block 100 in this variant is generally fan-shaped columnar. Correspondingly, the end positioning housing 111 is roughly fan-shaped plate with missing corners, the main body housing 112 is hollow and fan-shaped columnar with missing corners, the device positioning hole 1126 in the middle of the main body housing 112 is square plate, and the circuit board 221 is a matching square plate.

[0104] There are eight electrical connection receiving parts 121, and the receiving electrode part 1211 is shaped to correspond to the corner block of the sector column.

[0105] In this modified example, the other structures are basically the same as in Example 1.

[0106] Variation Example 5 This modification is a modification of Embodiment 1. In this modification, the same reference numerals are given to the same components as those of Embodiment 1, and the corresponding description is omitted.

[0107] Figure 15 is a perspective view of the multi-terminal functional building block in this modification.

[0108] As shown in Figure 15 , the multi-terminal functional building block 100 in this modification is different from that of Embodiment 1 in that it has a quarter-cylindrical shape as a whole, i.e., two of its side surfaces are rectangular planes, and the other side surface is a cylindrical surface. Accordingly, the end positioning case 111 has a substantially quarter-circular plate shape with a plurality of notches in its edge, and the main modeling case 112 has a hollow and notched quarter-cylindrical tube shape.

[0109] The six electric connection accommodating members 121 have accommodating electrode portions 1211 that have shapes corresponding to the notched quarter-cylindrical shape, i.e., the accommodating electrode portions 1211 have arc-shaped electrode contact surfaces.

[0110] In this modification, the other structures are substantially the same as those of Embodiment 1.

[0111] Modification 6 This modification is a modification of Embodiment 1. In this modification, the same reference numerals are given to the same components as those of Embodiment 1, and the corresponding description is omitted.

[0112] Figure 16 is a perspective view of the multi-terminal functional building block in this modification, Figure 17 is an exploded view of the multi-terminal functional building block in this modification.

[0113] As shown in Figure 16 and Figure 17 , the multi-terminal functional building block 100 in this modification is different from that of Embodiment 1 in that it has a cylindrical shape as a whole. Accordingly, the end positioning case 111 has a substantially circular plate shape with a plurality of notches in its edge, and the main modeling case 112 has a hollow and notched cylindrical tube shape. The device positioning hole 1126 in the middle of the main modeling case 112 is a square through hole. The circuit board also has a square plate shape, but the electric contacts are provided in the middle of the edge of the circuit board. Two positive contacts are respectively provided on a pair of opposite edges of the circuit board, and two negative contacts are respectively provided on another pair of opposite edges of the circuit board.

[0114] The accommodating electrode portions 1211 of the electric connection accommodating members 121 have shapes matching the edge of the end of the cylindrical shape, i.e., they have an arc-shaped electrode contact surface. The fitting portions 1212 extend from one edge of the accommodating electrode portions 1211, and the fitting portions 1212 have a strip-shaped fitting groove 1217 on one side. Accordingly, the corners of the main modeling case 112 have positioning ends matching the strip-shaped fitting groove 1217.

[0115] In this modification, other structures are basically the same as in Embodiment 1.

[0116] Modification Seven This modification is a modification of Embodiment 1, and in this modification, the same reference numerals are given to the same constituent elements as in Embodiment 1, and the corresponding description is omitted.

[0117] Figure 18 is a perspective view of the multi-terminal functional building block in this modification.

[0118] As shown in Figure 18 compared with Embodiment 1, the difference is that the multi-terminal functional building block 100 in this modification is also in the shape of a cube, but each side surface of the tripartite housing 110 has a square facet 113 composed of four triangular facets, with the center being concave.

[0119] Since the outer surface of the housing has a concave facet, the housing has better structural strength, can better disperse external force, resist deformation, reduce the probability of damage when the functional building block falls, and also allows the user to better hold the building block.

[0120] In addition, the facet has a refraction effect on the light emitted by the internal light-emitting device, and the light is dispersed in all directions, allowing the light to be more uniform and soft, and the light-emitting range to be wider, and also allowing different brightness and light and shadow to be presented at multiple angles. Furthermore, when multiple functional building blocks with facets and different light colors are spliced together, the light of the multiple functional building blocks is refracted through the facets and superimposed on each other, and the color transition of the light is also more natural. Therefore, the user has a better visual experience. Optionally, the facet can have a gradually changing thickness, for example, each triangular facet has a thinner thickness near the center point and a thicker thickness near the edge of the facet, or vice versa, to enhance the above effects.

[0121] In this modification, other structures are basically the same as in Embodiment 1.

[0122] Embodiment Three Figure 19 is a combined example of the building toy in this embodiment.

[0123] As shown in Figure 19 this embodiment exemplarily provides a building toy and shows one of the splicing and combining forms that it can have, and the building toy 400 includes a plurality of building units and a power building block 300, each building unit containing two or more functional building blocks with matching splicing ends.

[0124] Exemplarily, the building block toy 400 comprises the power block 300, a first building block unit 410, a second building block unit 420, a third building block unit 430, a fourth building block unit 440, and a fifth building block unit 450.

[0125] The first building block unit 410 comprises a conical function block 411 and a cylindrical function block 412, both of which have matching joint ends, are circular, and have two pairs of electrode portions correspondingly arranged at the edges of the joint ends. The cylindrical function block 412 is a multi-terminal function block of the sixth variant.

[0126] The second building block unit 420 comprises a short triangular square pyramid function block 421 and a plurality of triangular prism function blocks 422, both of which have matching joint ends, are square, and have a pair of electrode portions correspondingly arranged at the corners of the joint ends. The triangular prism function block 422 is a multi-terminal function block of the second variant.

[0127] The third building block unit 430 comprises a long triangular square pyramid function block 431 and a cubic function block 432, both of which have matching joint ends, are square, and have two pairs of electrode portions correspondingly arranged at the corners of the joint ends. The cubic function block 432 is a multi-terminal function block of the first embodiment.

[0128] The fourth building block unit 440 comprises a semi-cylindrical function block 441 and a cubic function block 432, both of which have matching joint ends, are square, and have two pairs of electrode portions correspondingly arranged at the corners of the joint ends.

[0129] The fifth building block unit 450 comprises a plurality of fan-shaped function blocks 451 and a plurality of quarter-cylindrical function blocks 452. The fan-shaped function block 451 is a multi-terminal function block of the fourth variant, and the quarter-cylindrical function block 452 is a multi-terminal function block of the fifth variant.

[0130] The fan-shaped function block 451 has a first joint end and a second joint end. The first joint end is the end corresponding to the two rectangular outer surfaces, and the second joint end is the end corresponding to the concave arc-shaped outer surface. The first joint end of the fan-shaped function block 451 is used for jointing with the first joint end of another fan-shaped function block 451.

[0131] The cylindrical function block 452 has a third joint end, which is the end corresponding to the arc-shaped outer surface. The third joint end is used for jointing with the second joint end of the fan-shaped function block 451. The second joint end and the third joint end are shape-matched, and the electrode distributions on the two kinds of joint ends are correspondingly arranged.

[0132] The conical functional building block 411, the short triangular square conical functional building block 421, the long triangular square conical functional building block 431, and the half-cylindrical functional building block 441 in the building block units described above are single-end type functional building blocks, which have similar structures to the multi-end type functional building blocks, and the structures thereof will be briefly described below.

[0133] Figure 20 is a perspective view of a single-end type functional building block in the present embodiment, Figure 21 is an exploded view of a single-end type functional building block in the present embodiment.

[0134] As shown in Figure 20 and Figure 21 , taking the single-end type functional building block 200 and the short triangular square conical functional building block 421 as examples, the whole thereof is in the shape of a triangular square cone, the bottom surface thereof is a square, and four corners of the bottom surface are respectively provided with an electrode part, in which two on one diagonal line are positive electrode parts 2211A, and two on the other diagonal line are negative electrode parts 2211B.

[0135] The single-end type functional building block 200 comprises a two-part shell 210, a planar electric functional assembly 220 provided on the shell 210, and a plurality of magnetic attraction members 230.

[0136] The two-part shell 210 comprises a positioning shell 211 and a modeling shell 212.

[0137] The positioning shell 211 comprises a plate-shaped part with four corners missing (i.e., in the shape of a relatively wide cross-shaped plate) and a grid-shaped rib protruding from one side surface of the plate-shaped part, and has a plurality of first notches 2111, a plurality of electrode positioning grooves 2112, a device positioning groove 2113, and a plurality of positioning protrusions 2114.

[0138] The first notches 2111 are rectangular notches formed at each corner of the positioning shell 211.

[0139] The electrode positioning grooves 2112 are open corner-type grooves used as clamping positioning grooves for the electrode parts, and are formed beside each first notch 2111, with the groove bottom being the edge part at the corner missing of the plate-shaped part, in the shape of a V-shaped plate, and the two side walls being one side surface of the rib beside the corner missing of the plate-shaped part.

[0140] The device positioning groove 2113 is formed in the middle of the side surface of the positioning shell 211 with the grid-shaped rib, and a plurality of positioning protrusions 2114 in the shape of small rectangular columns are respectively formed at each side wall in the device positioning groove 2113, with the protrusion heights of the four positioning protrusions 2114 being the same, and the upper end surfaces thereof being flat surfaces parallel to the plate-shaped part.

[0141] The modeling shell 212 is generally triangular pyramid with one end open and missing corners. The corner of the modeling shell 212 has a plurality of second notches 2121, and each corner has a V-shaped buckle portion (positioning end) and a magnet limiting portion. The structure of the corner of the modeling shell 212 in this embodiment is similar to that of the first embodiment.

[0142] Except for the mounting structure of the open end, the remaining part of the modeling shell 212 is only used for modeling, and can be made into various shapes according to needs, such as the above-mentioned long triangular pyramid, semicircular cylinder, cone, etc., or can also be made into a hemispherical shape or a special-shaped box.

[0143] When the positioning shell 211 and the modeling shell 212 are combined into one, the first notch 2111 and the corresponding second notch 2121 are combined into a positioning notch.

[0144] The planar electric functional assembly 220 includes a plurality of electric connection containing components 221 and electronic components 222. One end of the electric connection containing component 221 is a positive electrode portion 2211A or a negative electrode portion 2211B, and is also used to contain the magnetic attraction member 230 and is embedded and fixed in the corresponding positioning notch. In addition, the electric connection containing component 221 also has an embedded portion, an extension portion, a contact portion, and a conductive portion. The embedded portion also has a corner-shaped embedded groove, and the V-shaped buckle portion of the corner of the modeling shell 212 can be embedded in the corner-shaped embedded groove to limit and fix the electrode portion. The difference is that the extension portion is a straight rod without a bending part.

[0145] The electronic component 222 also includes a circuit board 2221 and an electric functional device 2222. Each corner of one surface of the circuit board 2221 has an electric contact, and two of them on one diagonal line are positive contacts, and two of them on the other diagonal line are negative contacts. The circuit board 2221 is embedded in the device positioning groove 2113 in the middle of the positioning shell 211, and the four corners are pressed by the four electric connection containing components 221 to fix the circuit board 2221. The electric functional device 2222 is welded and fixed in the middle of one surface of the circuit board 2221 and faces the modeling shell 212. It can be seen that there is no other structure between the electric functional device 2222 and the modeling shell 212. When it is a light-emitting device, the light emitted can be transmitted without obstruction.

[0146] The structures of several other single-end functional building blocks are similar.

[0147] The power building block 300 is a multi-end functional building block of the second embodiment.

[0148] As Figure 19As shown, the set of building blocks 400 of the present variant example can be assembled into a structure similar to a castle. Three building block units (i.e. the second to fourth building block units) are respectively connected to three sides of the power supply building block 300, the first building block unit 410 is connected to the side of the second building block unit 420, and the fifth building block unit 450 is connected to the side of the fourth building block unit 440, so that one power supply building block 300 can supply power to all the building block units. Of course, the building blocks 400 can also be assembled into other shapes, and the power supply building block can be connected to any position.

[0149] In addition, as shown in the figure, since the positive electrode part and the negative electrode part at the upper and lower ends of the cylindrical functional building block 412 can also serve as a pair of electrode parts, and the distribution (spacing) of the pair of electrode parts is the same as that of the pair of electrode parts on the triangular prism functional building block 422, the side surface of the cylindrical functional building block 412 can also be in contact with one edge of the triangular prism functional building block 422, so that the two pairs of electrode parts are in contact with each other, so that the electronic components in the cylindrical functional building block 412 and the conical functional building block 411 are also connected to the circuit. Although this type of connection is less stable than the connection by using matching connection ends (at least two pairs of electrode parts are connected, and at least two pairs of magnetic attraction members are magnetically attracted and fixed), it provides more possibilities for connection. Similarly, the pair of electrode parts on the cylindrical functional building block 412 can also be in contact with the pair of electrode parts on the cubic functional building block 432 to connect them to the circuit.

[0150] In the present embodiment, the other structures are basically the same as those in Embodiment 1.

[0151] In addition, in the present embodiment, the number of functional building blocks in a set of building blocks is relatively small, and there is only one power supply building block. In fact, a set of building blocks can include any number of functional building blocks, and the number of power supply building blocks can also be multiple. The ratio of the number of power supply building blocks to the number of other functional building blocks (functional building blocks that consume electricity) depends on the parameters of the power storage device, the parameters of each electrical functional device, the composition of the circuit board and its parameters, etc. Preferably, the ratio of the number of power supply building blocks to the number of other functional building blocks can be 1:20-1:50.

[0152] The above embodiments and variants show that the multi-terminal functional building blocks can have a variety of shapes, but the shapes of the multi-terminal functional building blocks are not limited to this, and other desired shapes can also be made, such as pentagonal or hexagonal columns, columns with concave or convex middle parts, etc. The single-terminal functional building blocks used with them can also be in the shape of a triangular pyramid with a pentagonal or hexagonal base, etc.

[0153] The power supply building block can also adopt different shapes according to the above embodiments and variants, but considering the versatility, the cubic shape is more preferred.

[0154] Eighth Modification This modification is a modification of Embodiment Three, in which the same reference numerals are assigned to the same constituent elements as in Embodiment Three, and the corresponding description is omitted.

[0155] Figure 22 is a perspective view of a single-end type functional building block in this modification.

[0156] As shown in Figure 22 the difference from Embodiment Three is that the single-end type functional building block 200 of this modification is also a short triangular square pyramid, but the outer surface of the two-part housing 210 includes a plurality of facets. Specifically, the outer surface of the positioning housing 211 has a square facet 213 composed of four triangular facets, with the center concave. The plurality of triangular outer surfaces of the modeling housing 212 each have a triangular facet 214 composed of three triangular facets, with the center concave.

[0157] In this modification, the other structures are substantially the same as in Embodiment Three.

[0158] In addition, the plurality of other shaped functional building blocks shown in the above-described modifications can also have similar facets. For example, the trapezoidal outer surface of the housing of the trapezoidal functional building block can also have a trapezoidal facet, i.e., also composed of four triangular facets, but the size and angle of each triangular facet are different. For another example, the square outer surface of the sector-shaped functional building block can also have a square facet, and the arc-shaped outer surface can also have a corresponding arc-shaped facet, i.e., a facet composed of four curved triangular facets.

[0159] The above-described embodiments are only used to illustrate the specific implementation of the present application, and the present application is not limited to the description range of the above-described embodiments. Those skilled in the art should understand that the present application is not limited by the above-described embodiments, and the above-described embodiments and the description in the specification only illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.

[0160] For example, in the above embodiment, the building block toy is used for playing by the user, especially by children. In an alternative, the building block toy can also be used for other purposes. For example, the electric functional device of the multi-terminal functional building block is a light emitting device, and the light emitting device is in the shape of a number, a letter, a word, a symbol, etc. The building block toy can be used to form a light emitting sentence or a mathematical formula, etc. Thus, the building block toy can be used for teaching children, or used as a light emitting advertising board, a holiday decoration, etc. Alternatively, the electric functional device of the multi-terminal functional building block is a light emitting device, and the light emitting device is a relatively energy-saving and long-life light emitting device. The building block toy can also be used as a light emitting lamp.
