[0002] Train-themed building block sets include multiple carriages that need to be connected using a linkage structure to ensure stable connection and flexible turning. To enhance the playability and aesthetics of these sets, lighting features have been added, powered by a battery box.

[0003] In related technologies, the connection of modular train carriages mainly includes convex-groove snap-fit ​​connections, pin-shaft rotation connections, hinge-type folding connections, and ordinary magnetic connections. However, if lighting or electrical connections are to be added to the modular set, there is no good electrical connection device or way to hide the wiring between the carriages. Therefore, the existing technology has the following problems: firstly, the connecting wires are difficult to hide, and exposed wires affect the appearance; secondly, the existing carriage connecting parts cannot realize the electrical connection function.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0037] This application relates to a building block set toy (hereinafter referred to as the set toy). Please refer to [link to relevant documentation]. Figure 1 and Figure 2Toy sets typically include at least two interconnectable or detachable carriages 2000, such as toy train carriages 2000 or other types of toy vehicles, where one vehicle can tow another. The following description uses a train carriage 2000 as an example. Train-themed toy sets include multiple carriages 2000. These carriages 2000 need to be securely connected while also allowing for free turning to meet the turning requirements of a moving train. Therefore, the carriages 2000 are connected by a block connection structure 1000. That is, each carriage 2000 has a block connection structure 1000 at at least one end, and the block connection structures 1000 of two carriages 2000 interlock to connect the two carriages 2000. Based on this, to meet the electrical connection requirements between the carriages 2000, this application proposes a new block connection structure 1000, which will be described in detail below.

[0038] Please see Figures 1 to 4The first aspect of this application provides a building block connection structure 1000, which includes a connector 100 and a rotating member 200. The connector 100 is provided with a first splicing structure 150, which is disposed at the top and / or bottom of the connector 100 and is used to connect external building blocks. The rotating member 200 is rotatably disposed in the connector 100 and is provided with a first conductive structure 300 and a connecting structure 400. The connecting structure 400 is used to detachably connect with the connecting structure 400 in another building block connection structure 1000. When the two connecting structures 400 are connected to each other, the corresponding first conductive structure 300 is electrically connected. The first splicing structure 150 can be used to connect the building block connection structure 1000 to external building blocks (such as building blocks on a carriage 2000 or building blocks constituting the carriage 2000), thereby fixing the building block connection structure 1000 to the carriage 2000 together. Optionally, the first splicing structure 150 can be provided at both the top and bottom of the connector 100, or it can be provided only at either the top or the bottom. By installing the modular connecting structure 1000 on each of the two carriages 2000, and connecting the rotating parts 200 of the two modular connecting structures 1000 to each other, the connection between adjacent carriages 2000 can be achieved. Since both the joining structure 400 and the first conductive structure 300 are located on the rotating parts 200, the rotating parts 200 of the two modular connecting structures 1000 can be detachably connected using the joining structure 400. Simultaneously, the two first conductive structures 300 also contact each other to achieve a conductive connection between the two modular connecting structures 1000, thereby achieving the effect of electrical connection between the two carriages 2000. Therefore, by adopting the modular connection structure 1000 provided in this application, electrical connection is achieved simultaneously with the docking of the two carriages 2000. On the one hand, this avoids the need for additional conductive wires, thereby simplifying the circuit design between the two carriages 2000 and solving the problem of exposed conductive wires at the connection point of the carriages 2000. It also avoids the problems of exposed wires being easily tangled, scraped off, or caught in the connection point of the carriages 2000, thus improving the reliability of the conductive connection between the carriages 2000. On the other hand, the mutual connection of the joint structures 400 on the two rotating parts 200 can enhance the connection stability between the carriages 2000, reduce the risk of open circuit between the two first conductive structures 300, and help improve the stability and reliability of the electrical connection of the first conductive structures 300.

[0039] It is understood that one end of the first conductive structure 300 is used for electrical connection with a first conductive structure 300 on another rotating component 200, and the other end is connected to electrical components inside the carriage 2000, such as electrical appliances (lights, speakers, etc.) or power supply components (battery boxes, etc.). Exemplarily, the first conductive structure 300 can be connected to electrical components inside the carriage 2000 through structures such as conductive wires, metal sheets, PCB circuit boards, flexible circuit boards, ribbon cables, etc., and can be routed inside or outside the rotating component 200, without specific limitations here.

[0040] Please see Figures 4 to 6 ,in, Figure 4 This is a schematic diagram showing the end faces 201 of two rotating parts 200 facing each other. Figure 5 This is a schematic diagram showing the rotating parts 200 of two building block connecting structures 1000 placed close to each other. Figure 6 This is a schematic diagram showing the mutual docking of rotating parts 200 of two block connection structures 1000. Specifically, it shows the mutual docking of block connection structures 1000a and 1000b. The joining structure 400 can achieve the connection of the two rotating parts 200 by means of magnetic attraction, friction, etc.

[0041] In some embodiments, please refer to Figure 20 The joining structure 400 includes a magnet 233. When the end faces of the rotating parts 200 of the two building block connecting structures 1000 are aligned with each other, the corresponding two magnets 233 are magnetically connected to each other.

[0042] Optionally, the rotating component 200 also includes a magnet compartment 230, within which a magnet 233 is rotatably disposed. When the two modular connecting structures 1000 are joined, their respective rotating components 200 face each other and approach each other. At this time, the magnet 233 can be rotated so that the opposite magnetic poles of the two magnets 233 are aligned, meaning that after the magnet 233 is rotated, either of the two magnetic poles faces the end face 201 of the rotating component 200, thereby achieving a magnetic connection between the two modular connecting structures 1000. Optionally, the magnet compartment 230 includes an interconnected receiving portion 231 and a clearance portion 232. The receiving portion 231 keeps the magnet 233 stable after rotation, and the clearance portion 232 provides space for the magnet 233 to rotate within the magnet compartment 230. In this way, only one magnet 233 needs to be placed in the magnet compartment 230 to satisfy the magnetic connection of any two modular connecting structures 1000, improving the adaptability and compatibility of the modular connecting structures 1000. For example, the magnet can be cylindrical, with two magnetic poles located at the bottom ends of the cylinder. When flipped, it rotates along an axis L0 with any diameter on the bottom surface of the cylinder, thereby changing the distribution of the magnetic poles. Correspondingly, the clearance portion 232 can be a spherical or hemispherical recessed space, providing sufficient space for the rotation of the magnet 233. By providing the magnet 233 within the rotating member 200, the engaging force between the two rotating members 200 can be further increased. This ensures sufficient connection strength between adjacent carriages 2000 in the event of vibrations or other issues during the use of the toy train, preventing the carriages 2000 from becoming disengaged.

[0043] In some embodiments, the rotating member 200 includes two identical half-shells 240, which are symmetrically arranged about the axis of the magnet compartment 230. Each half-shell 240 has a snap-fit ​​structure 250. The two half-shells 240 enclose the magnet compartment 230, and the snap-fit ​​structures 250 of the two half-shells 240 are interlocked. The rotating member 200 is installed using the interlocking method of the two half-shells 240, which facilitates the insertion and encapsulation of the magnet 233 within the magnet compartment 230. The snap-fit ​​structure 250 may include a hook 251 and a slot 252, which are located on opposite sides of the opening of the half-shell 240. When the two half-shells 240 are closed, the hook 251 and the slot 252 are interlocked. Since the two half-shells 240 have identical structures and are symmetrically arranged about the axis of the magnet compartment 230, the rotating component 200 formed by assembling the two half-shells 240 has symmetrical structures on both sides. When the rotating component 200 is installed into the connector 100, it can be installed without distinguishing between directions, reducing the assembly difficulty of the modular connection structure 1000 and improving the structural adaptability of the rotating component 200. At the same time, the identical structure of the two half-shells 240 reduces the number of component types and molds required for the modular connection structure 1000, simplifying its manufacturing process.

[0044] In some embodiments, the joining structure 400 includes a first joining member 410 and a second joining member 420 disposed on the end face 201 of the rotating member 200, and the end faces 201 of the rotating members 200 of the two building block connection structures 1000 abut against each other so that the first joining member 410 on one building block connection structure 1000 engages with the second joining member 420 on the other building block connection structure 1000.

[0045] Since the first connecting member 410 and the second connecting member 420 are disposed on the end faces 201 of the rotating members 200, when the two rotating members 200 are mated together, their end faces 201 are positioned opposite each other, so that the first connecting member 410 on one end face 201 corresponds to the second connecting member 420 on the other end face 201. Typically, the rotating members 200 also contain magnets 233. When the two rotating members 200 are mated together, the magnets 233 can attract each other, thus providing magnetic attraction for the connection of the two rotating members 200. Furthermore, the method of connecting the first connecting member 410 and the second connecting member 420 can further increase the contact area and connection strength between the end faces 201 of the two rotating members 200, thereby helping to improve the connection reliability of the two modular connection structures 1000. In addition, due to the mutual cooperation of the first coupling member 410 and the second coupling member 420, the two rotating members 200 can make the two end faces 201 roughly fit together after they are mated, avoiding the formation of too large a gap between the end faces 201 and ensuring the reliability of the mating of the rotating members 200.

[0046] For example, please refer to Figure 4 The first coupling member 410 includes a protrusion 411, and the second coupling member 420 includes a groove 421. The protrusion 411 and the groove 421 are fitted together. The interlocking action of the protrusion 411 and the groove 421 creates sufficient fastening force between the two rotating members 200, preventing loosening. Of course, other alternative embodiments can be found in the following description. Figure 7 The first connecting member 410 includes a hook 412, and the second connecting member 420 includes a groove 422. The hook 412 and the groove 422 engage to engage. Using a snap-fit ​​method to connect the second rotating member 200 also achieves good connection strength.

[0047] Based on the first connector 410 and the second connector 420, the following will describe various configurations of the first conductive structure 300.

[0048] In the first example, please refer to Figure 8 and Figure 9The first conductive structure 300 includes a first conductive block 310 disposed on the outer surface of the protrusion 411 and a second conductive block 320 disposed on the inner surface of the groove 421. When the protrusion 411 engages with the groove 421, the first conductive block 310 and the second conductive block 320 are electrically connected. Specifically, the outer surface of the protrusion 411 can be the outer peripheral side surface of the protrusion 411 (e.g., Figure 8 (as shown) or top surface (such as) Figure 9 As shown, the inner surface of the groove 421 can be the bottom surface or the inner circumferential surface of the groove 421. The first conductive block 310 can be a metal sheet disposed on the top surface of the protrusion 411, or a metal ring disposed on the outer circumferential surface of the protrusion 411. The second conductive block 320 can be a metal sheet disposed on the bottom surface of the groove 421, or a metal ring disposed on the inner circumferential surface of the groove 421. Since the outer surface of the protrusion 411 and the inner surface of the groove 421 can cooperate with each other, the first conductive block 310 is disposed on the outer surface of the protrusion 411, and the second conductive block 320 is disposed on the inner surface of the groove 421. In this way, when the protrusion 411 and the groove 421 are inserted into each other, the first conductive block 310 and the second conductive block 320 can contact each other to form a conductive connection. The fastening force generated when the protrusion 411 and the groove 421 are inserted into each other helps to improve the stability of the conductive connection between the two rotating parts 200.

[0049] In the second example, please refer to Figure 10 The first conductive structure 300 includes a first elastic pin 311 disposed within the protrusion 411 and a first conductive sheet 321 disposed at the bottom of the groove 421. The first elastic pin 311 protrudes from the top surface of the protrusion 411. When the protrusion 411 engages with the groove 421, the first elastic pin 311 abuts against the first conductive sheet 321. The elastic force of the first elastic pin 311 increases the interaction force between the first elastic pin 311 and the first conductive sheet 321, thereby improving the reliability of the conductive contact.

[0050] In the third example, please refer to Figure 11The first conductive structure 300 includes a second conductive sheet 312 disposed on the outer periphery of the protrusion 411 and an elastic conductive block 322 disposed on the inner wall of the groove 421. When the protrusion 411 engages with the groove 421, the elastic conductive block 322 abuts against the second conductive sheet 312. Optionally, the second conductive sheet 312 on the outer periphery of the protrusion 411 can be configured as an annular conductive sheet to facilitate cooperation with the elastic conductive block 322. Alternatively, an annular groove is provided on the outer periphery of the protrusion 411, and the second conductive sheet 312 is disposed in the annular groove to facilitate the elastic conductive block 322 being engaged in the annular groove. The elastic conductive block 322 has an elastic force that protrudes along the center of the groove 421, which facilitates the elastic conductive block 322 abutting against the outer peripheral surface of the protrusion 411. A barb 3221 can be provided at the end of the elastic conductive block 322, which can be engaged in the annular groove on the outer periphery of the protrusion 411. As an alternative implementation, the elastic conductive block 322 can also be replaced with an ordinary conductive block that does not have elasticity. When the protrusion 411 and the groove 421 are inserted and matched, the conductive block and the second conductive sheet 312 are interference-fitted, and the extrusion force generated between them can improve the reliability of the conductive connection.

[0051] The three examples described above provide different configurations of the first conductive structure 300. These configurations provide a force for the conductive contact of the first conductive structure 300 while the first connector 410 and the second connector 420 are connected to each other. This helps to avoid poor conductive contact and circuit breakage caused by vibration and friction, thereby improving the stability and reliability of the conductive connection between the two modular connection structures 1000. At the same time, since the first conductive structure 300 is located on the connector 400, it avoids occupying additional space on the rotating member 200, thus saving space on the rotating member 200 and making the design of the first conductive structure 300 and the connector 400 more compact.

[0052] The first conductive structure 300 can be disposed on the joining structure 400, or it can be disposed directly on the end face 201 of the rotating member 200 without relying on the joining structure 400. Of course, the first conductive structure 300 can be disposed on both the joining structure 400 and the end face 201 of the rotating member 200. Therefore, this application does not limit the specific location of the first conductive structure 300. The following will describe in detail the embodiment in which the first conductive structure 300 is directly disposed on the end face 201 of the rotating member 200.

[0053] In some embodiments, please refer to Figure 4 , Figure 12 and Figure 13The first conductive structure 300 is disposed on the end face 201 of the rotating member 200. The end faces 201 of the rotating members 200 of the two modular connecting structures 1000 are abutted together to make the first conductive structures 300 of the two modular connecting structures 1000 electrically connected. By abutting the end faces 201 of the two rotating members 200, the first conductive structures 300 located on the end faces 201 can contact each other to form an electrical connection. For example, the first conductive structure 300 can be a conductive sheet, and the conductive sheets on the two modular connecting structures 1000 contact each other to achieve conductivity. This arrangement mainly relies on the fastening force provided by the joining structure 400 to achieve the joining of the two rotating members 200, avoiding excessive concentration of fastening force in the first conductive structure 300, which could cause the first conductive structure 300 to loosen or fail, thus helping to improve the reliability of the first conductive structure 300.

[0054] In some embodiments, the first conductive structure 300 includes a first metal member 313 and a second metal member 323. When the end faces 201 of the two rotating members 200 are abutted, the first metal member 313 on the end face 201 of one rotating member 200 is electrically connected to the second metal member 323 on the end face 201 of the other rotating member 200. For example, as shown... Figure 12 As shown, the first metal component 313 includes a second elastic ejector pin 3131, and the second metal component 323 includes a third conductive sheet 3231. When the end faces 201 of the two rotating components 200 are aligned, the second elastic ejector pin 3131 abuts against the third conductive sheet 3231; or in other alternative embodiments, such as Figure 13 As shown, the first metal component 313 includes a conductive pin 3132, and the second metal component 323 includes a conductive slot 3232. When the end faces 201 of the two rotating components 200 are aligned, the conductive pin 3132 is inserted into the conductive slot 3232. The first metal component 313 and the second metal component 323 use an elastic pin to abut against the conductive sheet, which increases the interaction force between them and improves the reliability of the conductive contact. When the conductive pin 3132 and the conductive slot 3232 are inserted into each other, the contact area between the first metal component 313 and the second metal component 323 is increased, reducing the risk of them separating and causing a circuit break.

[0055] In some embodiments, such as Figure 14As shown, the first metal part 313 and the second metal part 323 are symmetrically arranged about the first center line L1, where the first center line L1 refers to the center line on the end face 201 of the rotating part 200 parallel to the rotation axis L0 of the rotating part 200. That is, the first metal part 313 and the second metal part 323 are distributed along the x-direction on the end face 201 of the rotating part 200. In this way, the rotating parts 200 on the two modular connection structures 1000 have the same structure and the same installation direction. When the end faces 201 of the two rotating parts 200 are opposite, the first metal part 313 and the second metal part 323 are respectively matched one-to-one. Only one mold needs to be designed when manufacturing the rotating part 200, thereby simplifying the part design of the modular connection structure 1000 and reducing the number of molds. Alternatively, in other alternative embodiments, such as Figure 15 As shown, the first metal part 313 and the second metal part 323 are symmetrically arranged about the second center line L2, where the second center line L2 refers to the center line on the end face 201 of the rotating part 200 that is perpendicular to the rotating shaft L0 of the rotating part. That is, the first metal part 313 and the second metal part 323 are distributed along the z-direction on the end face 201 of the rotating part 200. Thus, when one of the rotating parts 200 is mounted upright on the connecting part 100 (for example, the first metal part 313 is on top and the second metal part 323 is on the bottom), Figure 5 (As shown in the block connection structure 1000a), another rotating member 200 is mounted in the opposite direction on the connector 100 (e.g., the first metal member 313 is below and the second metal member 323 is above, such as...). Figure 5 As shown in the modular connection structure 1000b, when the end faces 201 of the two rotating parts 200 are facing each other, the first metal part 313 and the second metal part 323 on the two end faces 201 can be matched one-to-one. With this arrangement, the rotating parts 200 on the two modular connection structures 1000 are structurally identical. In use, only installation in different directions is required to achieve conductive connection of the first conductive structure 300 on the two rotating parts 200. Thus, only one mold needs to be designed when manufacturing the rotating parts 200, thereby simplifying the part design of the modular connection structure 1000 and reducing the number of molds required.

[0056] Referring to the arrangement of the first metal part 313 and the second metal part 323, the first connecting member 410 and the second connecting member 420 can also adopt a similar distribution, that is, the first connecting member 410 and the second connecting member 420 are about the first centerline L1 (e.g., Figure 14 (as shown) or the second midline L2 (as shown) Figure 15 As shown, the two rotating parts 200 are symmetrically arranged, so that the structures of the two mating and connecting rotating parts 200 are exactly the same, thereby improving the assembly compatibility and versatility of the rotating parts 200.

[0057] Based on this, in some embodiments, the first connecting member 410, the second connecting member 420, the first metal member 313, and the second metal member 323 are collinearly arranged on the end face 201 of the rotating member 200. That is, the first connecting member 410, the second connecting member 420, the first metal member 313, and the second metal member 323 are all arranged on the first centerline L1 of the end face 201 of the rotating member 200 (e.g., Figure 14 As shown), or both are set on the second centerline L2 (e.g. Figure 15 (As shown). In other embodiments, the line connecting the first connector 410 and the second connector 420 on the end face 201 of the rotating member 200 is perpendicular to the line connecting the first metal member 313 and the second metal member 323 on the end face 201 of the rotating member 200. The above-mentioned arrangement methods all help to fully and rationally utilize the space on the end face 201 of the rotating member 200, allowing the first connector 410, the second connector 420, the first metal member 313, and the second metal member 323 to be arranged in an orderly manner.

[0058] Alternatively, please refer to the following: Figure 11 Two magnet compartments 230 can be provided in the rotating component 200, and each magnet compartment 230 is provided with a magnet 233. On the end face 201 of the rotating component 200, the first connecting component 410, the second connecting component 420, the first metal component 313 and the second metal component 323 are all provided on the first center line L1 of the rotating component 200. The two magnets 233 are respectively provided on both sides of the first center line L1, and the line connecting the two magnets 233 is perpendicular to the first center line L1. In this way, the space on the end face 201 of the rotating component 200 can be fully utilized, and the interaction force between the two rotating components 200 is more evenly distributed on the end face 201.

[0059] In addition to the fastening force provided by the joint structure 400 for the joint of the rotating part 200, a coupling block 600 can be provided to further improve the connection strength between the two building block connection structures 1000. The following is a description of the coupling block 600.

[0060] In some embodiments, please refer to Figures 16 to 19 The modular connection structure 1000 also includes a coupling block 600. A second splicing structure 210 is provided on the outer periphery of the rotating component 200. The coupling block 600 is used to connect the second splicing structures 210 in the two modular connection structures 1000. Here, the coupling block 600 acts as a bridge, thereby connecting the rotating components 200 of the two modular connection structures 1000, such as... Figure 19As shown, based on the mutual connection of the end faces 201 of the rotating parts 200 using the joining structure 400, the coupling block 600 further strengthens the connection strength and stability between the rotating parts 200, preventing the two rotating parts 200 from becoming loose. Therefore, the coupling block 600 and the joining structure 400 provide double protection. The second splicing structure 210 is located on the outer periphery of the rotating parts 200, thus exposing the second splicing structure 210 for easy splicing of the coupling block 600, improving the convenience of splicing the coupling block 600. Furthermore, since the coupling block 600 connects to the rotating parts 200 on the outer periphery, it avoids affecting the joining structure 400 and the first conductive structure 300 located on the end face 201 of the rotating parts 200. That is, the second splicing structure 210 and the joining structure 400 are used independently, avoiding mutual interference.

[0061] For example, the coupling block 600 can be a building block with a splicing structure (e.g., splicing slot 610 or splicing post), and correspondingly, the second splicing structure 210 can be a splicing post or splicing slot 610. Figure 16 In the example shown, the second splicing structure 210 is a splicing column, and the coupling block 600 has a splicing groove 610, which is used to achieve splicing and mating with the splicing column.

[0062] In some embodiments, the coupling block 600 can further provide a conductive connection between the two modular connection structures 1000, thereby improving the reliability of the electrical connection. Specifically, please refer to... Figure 17 and Figure 18 The coupling block 600 is provided with a second conductive structure 620, and the outer periphery of the rotating component 200 is provided with a third conductive structure 220 connected in parallel with the first conductive structure 300. When the coupling block 600 and the rotating component 200 are spliced ​​together, the second conductive structure 620 and the third conductive structure 220 are electrically connected. Based on the conductive connection between the two rotating components 200 achieved by the first conductive structure 300, the second conductive structure 620 can electrically connect the third conductive structure 220 on the two rotating components 200, thereby playing a safety role. When the first conductive structure 300 experiences risks such as poor contact or failure, the interconnection of the second conductive structure 620 and the third conductive structure 220 can ensure a stable and good electrical connection between the two modular connecting structures 1000.

[0063] It is understood that one end of the third conductive structure 220 is used for electrical connection with the second conductive structure 620, and the other end is directly or indirectly connected to electrical components inside the carriage 2000, such as electrical appliances (lights, speakers, etc.) or power supply components (battery boxes, etc.). For example, the third conductive structure 220 can be directly connected to the electrical components inside the carriage 2000 through conductive wires, metal sheets, PCB circuit boards, flexible circuit boards, ribbon cables, etc., and can be routed inside or outside the rotating part 200. Alternatively, the third conductive structure 220 can be indirectly connected to the electrical components inside the carriage 2000 through the first conductive structure 300; no specific limitations are made here.

[0064] It should be noted that the third conductive structure 220 and the first conductive structure 300 are connected in parallel in the circuit design. In this way, if either the third conductive structure 220 or the first conductive structure 300 experiences an open circuit fault, it can avoid affecting the other and ensure the reliability of the entire circuit connection.

[0065] The specific configuration of the second conductive structure 620 and the third conductive structure 220 will be explained below.

[0066] In the first example, please refer to Figure 17 and Figure 18 The coupling block 600 is provided with a splicing groove 610. The second conductive structure 620 includes a third metal part 621 disposed in the splicing groove 610. The second splicing structure 210 includes a protrusion 411. The third conductive structure 220 includes a fourth metal part 221 disposed on the end face and / or outer peripheral surface of the protrusion 411. When the coupling block 600 is spliced ​​with the second splicing structure 210, the third metal part 621 and the fourth metal part 221 are electrically connected. By utilizing the surface contact generated when the coupling block 600 and the second joining structure 400 are spliced ​​together, the third metal part 621 and the fourth metal part 221 are placed on these contact surfaces. In this way, the second splicing structure 210 and the coupling block 600 are electrically connected at the same time as splicing. The second splicing structure 210 and the coupling block 600 serve both splicing and conductive connection functions. Therefore, the third conductive structure 220 can avoid occupying additional space on the rotating part 200, thereby saving space on the rotating part 200 and making the design of the second conductive structure 620 and the third conductive structure 220 more compact. For example, both the third metal component 621 and the fourth metal component 221 can be conductive sheets. The conductive sheet of the third metal component 621 is disposed within the splicing groove 610 of the coupling block 600, and the conductive sheet can simultaneously conduct electricity to the fourth metal components 221 on both rotating components 200. The fourth metal component 221 can be an annular conductive sheet disposed on the outer periphery of the protrusion 411 of the second splicing structure 210, or it can be a conductive sheet disposed on the top surface of the protrusion 411. Conductive sheets can be disposed on both the outer periphery and the top surface of the protrusion 411, or one of them can be disposed at a single location.

[0067] In the second example, please refer to Figure 16 The coupling block 600 is provided with a splicing groove 610. The second conductive structure 620 includes a fifth metal part 622 disposed on the opening edge of the splicing groove 610. The outer periphery of the rotating member 200 is provided with a mating plane 202. The second splicing structure 210 is disposed on the mating plane 202. The third conductive structure 220 includes a sixth metal part 222 disposed on the mating plane 202. When the coupling block 600 is spliced ​​with the second splicing structure 210, the fifth metal part 622 and the sixth metal part 222 are electrically connected. By utilizing the surface contact generated by the opening edge of the splicing groove 610 and the mating plane 202, the fifth metal part 622 and the sixth metal part 222 are disposed on these contact surfaces. The force generated when the coupling block 600 is spliced ​​with the second splicing structure 210 can press the fifth metal part 622 and the sixth metal part 222 together to achieve a conductive connection. Moreover, these contact surfaces have a large surface area, which helps to increase the contact area of ​​the fifth metal part 622 and the sixth metal part 222, thereby improving the reliability of the conductive contact. For example, the fifth metal part 622 and the sixth metal part 222 can be in the form of conductive sheets, which helps to reduce the installation difficulty of the fifth metal part 622 and the sixth metal part 222.

[0068] Optionally, the sixth metal piece 222 may be an annular metal sheet surrounding the contour edge of the second splicing structure 210, such as... Figure 16 As shown, this simplifies the installation setup of the sixth metal part 222.

[0069] In some embodiments, please refer to Figure 15 The outer periphery of the rotating component 200 is provided with two mating planes 202. Both mating planes 202 are perpendicular to the first centerline L1 of the rotating component 200, that is, the line connecting the two mating planes 202 coincides with the first centerline L1 of the rotating component 200. Each mating plane 202 is provided with a second splicing structure 210. Figure 15 The rotating component 200 has second splicing structures 210 at both its upper and lower ends in the z-direction. Thus, regardless of the orientation in which the rotating component 200 is installed onto the connecting component 100, both ends of the first centerline L1 of the rotating component 200 always have the second splicing structures 210, facilitating connection with the second splicing structures 210 on the same side of another rotating component 200. In some embodiments, please refer again to... Figure 3The connector 100 is provided with a wire-concealing structure 120, which is used to accommodate the conductive wire electrically connected to the first conductive structure 300. The wire-concealing structure 120's function of containing and fixing the conductive wire prevents it from floating on the surface of the modular connecting structure 1000, reducing the risk of the conductive wire becoming loose or being scratched off. It also prevents the conductive wires on adjacent carriages 2000 from being exposed haphazardly, or even entering the rotating shaft L0 between the rotating member 200 and the connector 100. Simultaneously, when the two carriages 2000 are separated, the magnetic connection of the rotating member 200 and the engagement of the connecting structure 400 are disconnected. The wire-concealing structure 120 can still accommodate the conductive wire without affecting its rotational connection with the connecting member 100, facilitating the next magnetic reconnection of the two adjacent carriages 2000.

[0070] In some embodiments, the wire concealment structure 120 includes a wire concealment groove 121, which is at least located on the side surface of the support plate 140 opposite to the beam 130. The wire concealment groove 121 is used to hold the conductive wire in place. The conductive wire can be continuously fixed in the support plate 140 using the wire concealment groove 121, improving the fixing effect of the conductive wire. During operation, the user only needs to press the conductive wire into the wire concealment groove 121 to complete the installation of the conductive wire, or remove the conductive wire from the wire concealment groove 121 to complete the disassembly. Therefore, the wire concealment structure 120 using the form of the wire concealment groove 121 can improve the ease of operation for installing or removing the conductive wire. The wire concealment groove 121 can also hide the embedded part of the conductive wire, avoiding the conductive wire from being exposed and improving the appearance of the connection between the carriages. In some examples, the depth of the wire concealment groove 121 is greater than or approximately equal to the diameter of the conductive wire, thereby completely embedding and hiding the conductive wire within the wire concealment groove 121. The cable tray 121 is set on the side surface of the tray 140 away from the beam 130, so that more usable space can be obtained on the surface of the tray 140, increasing the length of the cable tray 121. It also makes it easier for users to install or remove conductive wires on the surface of the tray 140, avoiding obstruction by the beam 130.

[0071] Optionally, the wire concealment structure 120 can partially or completely conceal the conductive wires. Therefore, after the conductive wires are fixed, they can adhere to the surface of the block connection structure 1000 or be hidden inside the block connection structure 1000, reducing the exposed portion of the conductive wires and thus improving the appearance of the block connection structure 1000 and the toy set.

[0072] In some embodiments, the connector 100 includes a beam 130 and a support plate 140. The beam 130 includes a main body 131 and side wings 132 disposed at both ends of the main body 131. The support plate 140 is disposed on the main body 131, the wire-concealing structure 120 is disposed on the support plate 140, and the rotating member 200 is rotatably connected to the main body 131. The side wings 132 are provided with a fourth conductive structure 160, which is electrically connected to the first conductive structure 300. The support plate 140 can be used to connect to the carriage 2000, improving the connection strength between the modular connecting structure 1000 and the carriage 2000. The fourth conductive structure 160 can act as an electrical connection bridge between the first conductive structure 300 and the electrical components of the carriage 2000. That is, the fourth conductive structure 160 conducts electricity between the first conductive structure 300 and the electrical components on the carriage 2000, allowing for more flexible configuration of the electrical connection between the first conductive structure 300 and the electrical components of the carriage 2000. By setting the concealed wire structure 120 on the tray 140, the routing distance of the conductive wire can be shortened, making it easier to fix and hide the conductive wire leading out from the carriage 2000, thus making the structure of the modular connection structure 1000 and the carriage 2000 simpler and more compact. By using the main body 131 and side wing 132 on the beam 130 to respectively install the rotating component 200 and the fourth conductive structure 160, the installation of the fourth conductive structure 160 can be achieved simultaneously while satisfying the installation requirements of the rotating component 200. This avoids interference between the rotating component 200 and the fourth conductive structure 160, improving the independence of the rotating component 200 and the conductive structure during use, thereby enhancing the reliability of the modular connection structure 1000.

[0073] In some embodiments, please combine Figure 3 and Figure 21 The wire concealment structure 120 can also be disposed in the side wing 132, and the fourth conductive structure 160 can also be disposed in the tray 140. This increases the flexibility of the arrangement of the wire concealment structure 120 and the fourth conductive structure 160, meeting various installation requirements for the conductive wire and the fourth conductive structure 160. It is understood that the wire concealment structure 120 can be disposed simultaneously in the tray 140 and the side wing 132, or in either the tray 140 or the side wing 132. Similarly, the fourth conductive structure 160 can also be disposed simultaneously in the tray 140 and the side wing 132, or in either the tray 140 or the side wing 132. The arrangement of the wire concealment structure 120 and the fourth conductive structure 160 can have various combinations, and no specific limitation is made here.

[0074] For example, the fourth conductive structure 160 may be a circuit board 111, a terminal structure 110, etc. The first conductive structure 300 and the fourth conductive structure 160 may be electrically connected by means of wires, soldering, metal snaps, terminal structure 110 or other types of interfaces.

[0075] In some embodiments, a seat 134 is provided at the end of the side wing 132 away from the main body 131. The thickness of the seat 134 along the first direction y is greater than the thickness of the side wing 132, and a first splicing structure 150 is also provided on the surface of the seat 134 along the second direction x. Thus, the splicing structure on the seat 134 can be spliced ​​with other building blocks, enriching the shape of the carriage 2000. This splicing structure on the seat 134 can also be used to connect with splicing structures on the carriage 2000, thereby improving the connection strength between the connector 100 and the carriage 2000. Furthermore, when two carriages 2000 rotate relative to each other, the seat 134 can abut against the seat 134 of another carriage 2000, thereby limiting the relative rotation range of the carriages 2000. When building blocks are attached to the seat 134, the building blocks abut against the seat 134 of another carriage 2000 or the building blocks on the seat 134, which can also limit the rotation range of the carriage 2000.

[0076] In some embodiments, the surface of the seat 134 formed along the first direction y is also provided with a first splicing structure 150. Thus, the seat 134 can also be spliced ​​with other building blocks along the first direction y, enriching the shape of the carriage 2000. This splicing structure on the seat 134 can also be used to connect with splicing structures on the carriage 2000, thereby improving the connection strength between the connector 100 and the carriage 2000.

[0077] For example, such as Figure 21 As shown, the seat body 134 has a first splicing structure 150 on both sides of the first direction y, which takes the form of a splicing groove 610. In some examples, the splicing grooves 610 on the two sides of the seat body 134 in the first direction y can be non-intersecting countersunk holes; in other examples, the splicing grooves 610 on the two sides can be interconnected to form a through hole. This through hole can not only be used to splice with splicing columns of other splicing structures, but also serve as a wire concealment structure 120 for conductive wires to pass through, thereby fixing or guiding the conductive wires and helping to prevent the conductive wires from being exposed or shaking, which would affect the rotational connection of the two adjacent carriages 2000.

[0078] Optionally, two side wings 132 may be provided on the beam 130, and the two side wings 132 are symmetrically arranged about the main body 131. Two bases 134 may also be provided on the beam 130, and the two bases 134 are symmetrically arranged about the main body 131. In this way, the beam 130 has symmetrical structures at both ends along the third direction z, which helps to make the connecting member 100 more balanced in terms of force.

[0079] In some embodiments, the side wing portion 132 is provided with a mounting groove 133, and the fourth conductive structure 160 is detachably disposed within the mounting groove 133. Providing the mounting groove 133 not only increases the contact area between the side wing portion 132 and the fourth conductive structure 160, improving the installation stability of the fourth conductive structure 160, but also allows the mounting groove 133 to accommodate a portion of the fourth conductive structure 160, or even the entire fourth conductive structure 160, reducing the protrusion of the fourth conductive structure 160 on the surface of the side wing portion 132, resulting in a smoother surface and a more compact structure for the side wing portion 132. Taking the circuit board 111 as an example, the fourth conductive structure 160 can be plugged into and installed within the mounting groove 133, making the installation or removal of the circuit board 111 more convenient.

[0080] In some embodiments, please refer to Figure 6 The fourth conductive structure 160 includes a detachable conductive terminal structure 110. The mounting groove 133 is provided with an elastic structure 1331. The terminal structure 110 is detachably installed in the mounting groove 133 via the elastic structure 1331, and the terminal structure 110 is electrically connected to the first conductive structure 300. Using the terminal structure 110 to electrically connect to the first conductive structure 300 simplifies the installation and removal operations between the fourth conductive structure 160 and the first conductive structure 300, improving user convenience and usability. The elastic structure 1331 can be an elastic buckle with a pre-tightening force towards the mounting groove 133. Taking a circuit board 111 as an example, when the circuit board 111 is inserted into the mounting groove 133, the elastic buckle can abut against the surface of the circuit board 111, thus fixing the circuit board 111. Optionally, the circuit board 111 may be provided with snap-fit ​​holes 1110, such as through holes penetrating both surfaces of the circuit board 111 or blind holes located on one side surface. The surface of the elastic snap fastener is provided with protrusions 1332, which cooperate with the snap-fit ​​holes 1110 on the circuit board 111 to engage and improve the stability of the engagement. Compared with adhesive or bolt connections, using elastic snap fasteners to fix the circuit board 111 facilitates the installation or removal of the circuit board 111.

[0081] Taking the fourth conductive structure 160, which includes terminal structure 110 and circuit board 111, as an example, please refer to... Figure 4 Terminal structures 110 (e.g., female terminals) are disposed on circuit board 111, and terminal structures 110 (e.g., male terminals) are also disposed on the first conductive line 700. Circuit board 111 and the first conductive line 700 can be electrically connected or signal connected by interlocking the male and female terminals. One end of the first conductive line 700 is connected to an electrical component on the carriage 2000, and the other end is connected to circuit board 111 through terminal structure 110. The two modular connecting structures 1000 are electrically connected through the first conductive structure 300, thereby realizing the electrical connection between two adjacent carriages 2000.

[0082] For example, please refer to Figure 21 The mounting slot 133 has a curved, hollowed-out groove 1333. The curved portion of the hollowed-out groove 1333 forms an elastic structure 1331. The elastic structure 1331 has a pre-tightening force toward the circuit board 111. When the circuit board 111 is inserted into the mounting slot 133, the elastic structure 1331 can abut against the surface of the circuit board 111 until it aligns with and engages with the locking hole 1110. The surface of the elastic structure 1331 has a protrusion 1332, which engages with the locking hole 1110.

[0083] Secondly, please refer to Figure 22 This application provides a building block assembly 3000, including a first building block unit 1001 and a second building block unit 1002 that are detachably connected. Both the first building block unit 1001 and the second building block unit 1002 include a connector 100 and a rotating member 200. The top and / or bottom of the connector 100 are provided with a first splicing structure 150. The rotating member 200 is rotatably disposed in the connector 100. The connector 100 is provided with a first conductive structure 300. The rotating member 200 of the first unit is provided with a first connecting member 410, and the rotating member 200 of the second unit is provided with a second connecting member 420. When the first connecting member 410 and the second connecting member 420 are connected, the first conductive structure 300 of the first building block unit 1001 and the second building block unit 1002 are electrically connected. It is understood that the structures of the first building block unit 1001 and the second building block unit 1002 are largely the same as those of the building block connection structure 1000 provided in the first aspect. The difference lies in the configuration of the end face 201 of the rotating member 200, which differs from that of the building block connection structure 1000 provided in the first aspect. In the embodiment of the second aspect of this application, the first building block unit 1001 needs to be connected with the second building block unit 1002. Specifically, the first connecting member 410 is disposed on the rotating member 200 of the first unit, and the second connecting member 420 is disposed on the rotating member 200 of the second unit. When assembling the building blocks, the first building block unit 1001 and the second building block unit 1002 can be flexibly selected for splicing according to the actual situation.

[0084] Specifically, the specific configuration of the first connecting member 410 and the second connecting member 420 can refer to the building block connection structure 1000 provided in any embodiment of the first aspect of this application. For example, the first connecting member 410 includes a protrusion 411, and the second connecting member 420 includes a groove 421, with the protrusion 411 and the groove 421 engaging; or, the first connecting member 410 includes a hook 412, and the second connecting member 420 includes a slot 422, with the hook 412 and the slot 422 engaging. The engagement method and beneficial effects of the protrusion 411 and the groove 421 or the hook 412 and the slot 422 can be referred to the embodiments provided in the first aspect above, and will not be repeated here.

[0085] In some embodiments, the first conductive structure 300 may be disposed only on the first connector 410 and the second connector 420, or only on the end face 201 of the rotating member 200, or simultaneously on the first connector 410, the second connector 420, and the end face 201 of the rotating member 200; no limitation is made here. Specifically, the first conductive structure 300 of the first building block unit 1001 is disposed on the first connector 410, and the first conductive structure 300 of the second building block unit 1002 is disposed on the second connector 420; and / or, the first conductive structure 300 of the first building block unit 1001 is disposed on the end face 201 of the rotating member 200, and the first conductive structure 300 of the second building block unit 1002 is disposed on the end face 201 of the rotating member 200. The first conductive structure 300 can take the form of a conductive sheet, a conductive pin 3132 and a conductive slot 3232, an elastic pin and a conductive sheet, etc. For specific implementations, please refer to any of the embodiments provided in the first aspect of this application, which will not be repeated here.

[0086] In an alternative implementation, the coupling block 600 can provide both connection and conductivity for the two building block connection structures 1000 independently; that is, the two building block connection structures 1000 can achieve conductive connection solely through the coupling block 600.

[0087] Specifically, please refer to Figure 23 The third aspect of this disclosure provides a building block connection assembly 4000, including a coupling block 600 and a building block connection structure 1000. The building block connection structure 1000 includes a connector 100 and a rotating member 200. The connector 100 is provided with a first splicing structure 150, which is disposed at the top and / or bottom of the connector 100. The rotating member is rotatably disposed in the connector 100. The outer periphery of the rotating member 200 is provided with a second splicing structure 210 and a third conductive structure 220. The coupling block 600 is used to detachably connect the second splicing structure 210 of the two building block connection structures 1000. When the coupling block 600 is detachably connected to the second splicing structure 210 of the two building block connection structures 1000, the second conductive structure 620 and the third conductive structure 220 are electrically connected.

[0088] The coupling block 600 acts as a bridge, connecting the second splicing structure 210 on both block connection structures 1000 simultaneously. This connects the rotating parts 200 of the two block connection structures 1000, preventing them from becoming detached. The second splicing structure 210 is located on the outer periphery of the rotating part 200, making it exposed for easy assembly of the coupling block 600 and improving its convenience. Furthermore, the coupling block 600 and the second splicing structure 210 are detachably connected, facilitating the assembly and disassembly of the two carriages 2000 and enhancing the usability and fun of the train toy.

[0089] Since the third conductive structure 220 and the second splicing structure 210 are both simultaneously mounted on the rotating member 200, on the one hand, the coupling member is spliced ​​with the second splicing structure 210 while simultaneously achieving electrical contact between the third conductive structure 220 and the second conductive structure 620. Therefore, the practice of setting additional conductive wires can be avoided, thereby simplifying the circuit design between the two carriages 2000. On the other hand, when the two carriages 2000 are docked together, the two rotating members 200 do not rotate relative to each other. Therefore, by mounting the third conductive structure 220 on the rotating member 200, the problem of conductive wires being exposed at the connection point of the carriages 2000 due to the use of conductive wire connections can be avoided. It also avoids the problem of exposed wires being easily tangled, scraped off, or twisted into the connection point between the rotating member 200 and the connecting member 100, thereby improving the reliability of the conductive connection between the carriages 2000.

[0090] Optionally, the specific arrangement and corresponding beneficial effects of the second conductive structure 620 and the third conductive structure 220 can be referred to the description of the first aspect of this disclosure. In this embodiment, the second conductive structure 620 and the third conductive structure 220 can be the same as those in the embodiment of the first aspect, that is, the second conductive structure 620 includes a third metal member 621 disposed in the splicing groove 610, and the third conductive structure 220 includes a fourth metal member 221 disposed on the end face and / or outer peripheral surface of the protrusion 411, and the third metal member 621 and the fourth metal member 221 are electrically connected. Alternatively, in another alternative embodiment, the second conductive structure 620 includes a fifth metal member 622 disposed at the opening edge of the splicing groove 610, and the third conductive structure 220 includes a sixth metal member 222 disposed in the joint plane 202. When the coupling block 600 is spliced ​​with the second splicing structure 210, the fifth metal member 622 and the sixth metal member 222 are electrically connected. For example, the fifth metal part 622 and the sixth metal part 222 can be in the form of conductive sheets, which helps to reduce the installation difficulty of the fifth metal part 622 and the sixth metal part 222.

[0091] Alternatively, in this embodiment, other structural configurations and beneficial effects of the block connection structure 1000 can be referred to the description of any embodiment of the first aspect of this disclosure, and will not be repeated here.

[0092] Fourthly, this application also provides a building block set toy; please refer to it again. Figure 3 The building block set toy includes the building block connecting structure 1000 provided in any embodiment of the first aspect or the building block assembly 3000 provided in any embodiment of the second aspect, and a first conductive wire 700. One end of the first conductive wire 700 is connected to the first conductive structure 300, and the other end is used to connect to the electrical components of the carriage 2000. Alternatively, it includes the building block connecting assembly 4000 provided in any embodiment of the second aspect and a second conductive wire. One end of the second conductive wire is connected to the third conductive structure 220, and the other end is used to connect to the electrical components of the carriage 2000. In this way, while ensuring a stable physical and electrical connection between the two carriages 2000, it also enables an electrical connection between the carriage 2000 and the building block connecting structure 1000 (or between the carriage 2000 and the first building block unit 1001 or the second building block unit 1002), realizing the circuit connection between carriages 2000, thereby realizing the circuit setup of the entire train. For example, a battery box can be installed in any of the train carriages 2000. The conductivity between each carriage 2000 can be used to power all the carriages 2000, such as to power the lights on all the carriages 2000. This expands the ways to play with the train toy and increases the fun of using the building block set.

[0093] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
