Description

Technical Field

[0001] This utility model relates to the field of electronic educational equipment technology, and in particular to a vertical circuit board and a circuit experiment toy. Background Technology

[0002] In recent years, with the development of electronic technology and the popularization of STEM education concepts, modular circuit toys have gradually become an important carrier of educational tools and intellectually stimulating products due to their flexibility and interactivity. Traditional circuit toys mostly adopt a planar layout (such as breadboards or PCBs), connecting electronic components and modules through wires or plug-in methods.

[0003] However, this type of design has the following significant drawbacks: low space utilization efficiency; the planar layout requires components and modules to be laid out horizontally, occupying a large area and making it difficult to achieve compact assembly of complex circuits within a limited desktop space. The layout chaos is particularly pronounced when users need to operate multiple modules simultaneously, affecting experimental efficiency and operational intuitiveness.

[0004] The power supply design is redundant, and existing solutions typically rely on separate power modules (such as external battery boxes or adapters), which need to be connected to other modules via wires. This type of design not only leads to messy wiring but also occupies additional space due to the separation of the power module from the circuit board, reducing system integration.

[0005] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0006] To address the aforementioned issues, the present invention aims to provide a vertical circuit board and circuit experiment toy, which has advantages such as high space utilization, high power supply integration, and good connection stability.

[0007] This application provides a vertical circuit board with the following technical solution: a substrate having standardized mating structures distributed in a matrix on its surface, the standardized mating structures being connecting posts or connecting grooves for forming a detachable connection with the corresponding interface of a circuit module through mechanical interlocking; a support base connected to the lower end of the substrate through a rigid fixing structure, the support base being configured to provide a gravity bearing surface and ensure that the substrate is stably erected in a vertical orientation; the combination of the substrate and the support base forms a vertical mounting architecture for a modular circuit system.

[0008] In this design, the standardized mating structure on the substrate surface enables detachable connections of circuit modules through mechanical interlocking, solving the problem of large space occupation caused by the horizontal arrangement of components in traditional planar layouts. The support base is connected to the substrate through a rigid fixing structure, and its gravity-bearing surface design ensures the stability of the substrate's vertical orientation, overcoming the shortcomings of planar layouts in achieving three-dimensional assembly within limited space. The combined architecture of the substrate and support base enables vertical installation of the modular circuit system, improving space utilization efficiency.

[0009] This technical solution, through the synergistic effect of standardized interoperable structures and vertical support structures, simultaneously meets the requirements for compact assembly and stable installation of modular circuits within a limited space, effectively solving the problems of low space utilization and insufficient stability of traditional planar layouts.

[0010] Furthermore, this application proposes that a slot be provided on the rear side of the support base, and a connecting plate be provided on the bottom of the substrate. The connecting plate is embedded in the slot and fixedly connected by fasteners or a snap-fit ​​structure. The slot on the rear side of the support base and the connecting plate on the bottom of the substrate form a mechanical mating structure. The insertion of the connecting plate by the slot restricts lateral displacement, and the longitudinal fixing force is applied by the fasteners or snap-fit ​​structure, forming a rigid connection in three dimensions. This solution significantly improves the torsional resistance and vibration tolerance between the substrate and the support base through the dual action mechanism of insertion and locking, ensuring structural stability in the vertical orientation state.

[0011] Furthermore, this application also proposes that the slot is provided with a strip-shaped slit and a plurality of positioning grooves inside, the strip-shaped slit extending laterally along the slot, and the positioning grooves being spaced apart within the slot along the length direction of the strip-shaped slit; the connecting plate is provided with positioning ribs matching the strip-shaped slit, and a plurality of positioning posts spaced apart along the length direction of the positioning ribs; when the connecting plate is embedded in the slot, the positioning ribs are embedded in the strip-shaped slit, and the positioning posts are inserted into the corresponding positioning grooves.

[0012] This technical solution achieves precise three-dimensional positioning and multiple constraints between the substrate and the support base through the refined structural design of the slots and connecting plates. Specifically, the matching embedding of the positioning ribs and strip slots restricts the longitudinal displacement of the connecting plate within the slots, ensuring longitudinal alignment between the substrate and the support base. Furthermore, the insertion and engagement of the positioning posts and positioning slots, through multiple spaced positioning points, applies lateral and longitudinal fixing forces to the connecting plate, preventing lateral and longitudinal slippage caused by external forces or vibrations.

[0013] This solution utilizes a combined "rib-slot" and "column-groove" mechanism to simultaneously address the precise positioning and displacement resistance of the connection structure within a limited space. Through structural innovation, this technical solution balances connection strength, precision, and flexibility while maintaining a compact design, effectively resolving stability issues caused by assembly deviations in modular systems. It demonstrates significant practical value and technological advancement.

[0014] Furthermore, this application also proposes that the standardized mating structure is provided on the rear end surface of the support base for forming a detachable connection with the corresponding interface on the surface of the substrate.

[0015] Furthermore, this application proposes that the support base be constructed as a power module, with power access ports provided on the surfaces of the support base other than the gravity-bearing surface for supplying power to the circuit module. This construction method, where the support base functions as a power module, integrates the power supply function, avoiding the additional space occupied by independent power modules in traditional designs. The placement of the power access ports on non-gravity-bearing surfaces ensures power supply accessibility while maintaining the vertical stability of the substrate. This solution, by integrating the power function into the support structure, directly reduces the need for external wire connections and simultaneously improves the vertical space utilization of the system.

[0016] Furthermore, this application proposes that the power outlet is located on the top surface of the support base and close to the bottom of the substrate. The support base serves as the positioning structure for the power module and defines the spatial position of the power outlet. The placement of the power outlet on the top surface of the support base, combined with the layout design close to the bottom of the substrate, ensures that after the circuit module is connected to the substrate via a standardized mating structure, its power lines can connect to the power outlet via the shortest path.

[0017] Furthermore, this application also proposes that a battery compartment is provided inside the support base, and a removable cover plate is provided on the surface of the support base for sealing the battery compartment.

[0018] Furthermore, this application also proposes a circuit experiment toy, including the aforementioned vertical circuit board.

[0019] Furthermore, this application also proposes a circuit experiment toy, including the aforementioned vertical circuit board; circuit modules are connected to the surface of the substrate through a standardized interlocking structure, and the circuit modules are connected to the power outlet via power lines for power supply.

[0020] As can be seen from the above, the vertical circuit board and circuit experiment toy provided in this application realizes the three-dimensional layout and centralized power supply of the circuit modules through the vertically oriented substrate design and the integrated power supply support base. It solves the problems of low space utilization and power supply redundancy in traditional planar layouts, and has the advantages of high space utilization, high power supply integration and good connection stability.

[0030] Example 1:

[0031] like Figure 1-4 As shown, this embodiment relates to a vertical circuit board, including a substrate 1 and a support base 2. The surface of the substrate 1 has standardized mating structures 11 distributed in a matrix. These structures are connecting posts or connecting grooves, used to form a detachable connection with the corresponding interface of the circuit module through mechanical engagement. The support base 2 is connected to the lower end of the substrate 1 through a rigid fixing structure, configured to provide a gravity-bearing surface 21 and ensure that the substrate 1 is stably erected in a vertical orientation. The combination of the substrate 1 and the support base 2 forms a vertical mounting architecture for a modular circuit system. Specifically, the standardized mating structures 11 can be implemented as follows: the connecting posts are cylindrical protrusions; the connecting grooves are square or circular grooves for the connecting posts to be snapped into place. As a preferred embodiment, the gravity-bearing surface 21 can be designed as a rubber pad layer with anti-slip texture to enhance friction with the contact surface. This technical solution achieves a detachable connection of the circuit module through the standardized mating structures 11 on the surface of the substrate 1. The support base 2 is connected to the substrate 1 via a rigid fixing structure. Its gravity-bearing surface 21 is designed to ensure the vertical orientation stability of the substrate 1, overcoming the shortcomings of planar layouts in achieving three-dimensional assembly within a limited space, and solving the problem of large area occupation caused by the horizontal arrangement of components in traditional planar layouts. Compared with existing technologies, this solution, through the synergistic effect of the standardized interlocking structure 11 and the vertical support structure, simultaneously meets the requirements of compact assembly and stable erection of modular circuits within a limited space, effectively improving space utilization efficiency.

[0032] exist Figure 2-4 In the illustrated embodiment, a slot 22 is provided on the rear side of the support base 2, and a connecting plate 12 is provided on the bottom of the base plate 1. The connecting plate 12 is embedded in the slot 22 and fixedly connected by fasteners or a snap-fit ​​structure. Specifically, the slot 22 can be designed as a T-slot, dovetail slot, or rectangular slot, and its depth forms a transition fit or interference fit with the thickness of the connecting plate 12. The end of the connecting plate 12 can be configured as a protruding structure complementary to the shape of the slot 22, such as a trapezoidal cross section with chamfers or a straight plate structure with a limiting boss. The fasteners can be screws, bolts, or rivets, with their penetration direction perpendicular to the opening plane of the slot 22; the snap-fit ​​structure includes a mating assembly of an elastic latch and a limiting groove, wherein the latch is located on the side edge of the connecting plate 12, and the groove is formed in the inner wall of the slot 22. Thus, this technical solution achieves lateral displacement constraint through the mechanical interlock between the slot 22 and the connecting plate 12, and forms a three-dimensional rigid connection by combining the longitudinal fixing force provided by the fasteners or snap-fit ​​structure. Compared to the simple screwing or gluing fixation of existing planar circuit boards, this design significantly improves the torsional resistance and vibration stability of substrate 1 in a vertical state, making it particularly suitable for educational scenarios that require frequent module insertion and removal. Its innovation lies in integrating the insertion guide and multi-point locking mechanism into a single connection interface, which avoids the wobbling problem of substrate 1 commonly found in traditional vertical structures, while maintaining the convenience of modular assembly and disassembly.

[0033] like Figure 2 and 4In a further embodiment shown, the slot 22 is provided with a strip-shaped slit 221 and multiple positioning grooves 222. The strip-shaped slit 221 extends laterally along the slot 22, and the positioning grooves 222 are spaced apart within the slot 22 along the length of the strip-shaped slit 221. The connecting plate 12 is provided with positioning ribs 121 that match the strip-shaped slit 221, and multiple positioning posts 122 spaced apart along the length of the positioning ribs 121. When the connecting plate 12 is inserted into the slot 22, the positioning ribs 121 are inserted into the strip-shaped slit 221, and the positioning posts 122 are inserted into the corresponding positioning grooves 222. This technical solution achieves precise three-dimensional positioning and multiple constraints between the substrate 1 and the support base 2 through the refined structural design of the slot 22 and the connecting plate 12. Specifically, the matching insertion of the positioning ribs 121 and the strip-shaped slit 221 restricts the longitudinal displacement of the connecting plate 12 within the slot 22, ensuring longitudinal alignment between the substrate 1 and the support base 2. Furthermore, the insertion and engagement of the positioning post 122 and the positioning groove 222, through multiple spaced positioning points, applies lateral and longitudinal fixing forces to the connecting plate 12, preventing lateral and longitudinal slippage caused by external forces or vibrations. This solution, through a composite engagement mechanism of "rib-slit" and "post-groove," simultaneously solves the problems of precise positioning and displacement resistance of the connection structure within a limited space. This technical solution, through structural innovation, balances connection strength, precision, and flexibility under the premise of compact design, effectively solving the stability problems caused by assembly deviations in modular systems, and has significant practical value and technological advancement.

[0034] In an alternative solution, a standardized mating structure 11 is provided on the rear end face of the support base 2 to form a detachable connection with the corresponding interface on the surface of the substrate 1. Specifically, the standardized mating structure 11 is configured as a connecting post or a connecting groove, achieving connection through mechanical interlocking. Thus, this technical solution, by adding the standardized mating structure 11 to the rear end face, enables the support base 2 and the substrate 1 to form a detachable auxiliary connection in addition to rigid fixation. Its working principle is that when the interface on the surface of the substrate 1 mates with the mating structure on the rear end face of the support base 2, the mechanical interlocking action can distribute some of the load, thereby reducing stress concentration at the rigid connection point. Compared with existing technologies, this design significantly improves the scalability of the modular circuit system—users can flexibly increase or decrease the number of support bases 2 according to their needs without changing the main structure of the substrate 1.

[0035] In such Figure 1In a further preferred embodiment, the support base 2 is constructed as a power module. Power outlets 23 are provided on the surfaces of the support base 2, excluding the gravity-bearing surface 21, to provide power to the circuit module. The power outlets 23 can be standardized DC sockets, USB-C interfaces, or spring-loaded contact structures, with the specific interface type selected based on power supply requirements. As a preferred embodiment, the power outlets 23 are distributed in an array on the side facade of the support base 2, with the spacing between each outlet maintaining an integer multiple of the standardized mating structure 11 on the substrate 1, facilitating power line routing. Furthermore, a lithium battery pack, a dry cell battery compartment, or an AC-DC conversion module can be integrated inside the support base 2, with the battery compartment allowing for quick replacement via a sliding or flip-top cover 25. This technical solution integrates the power supply function into the support structure, achieving an integrated design of the power supply system and mechanical support. Specifically, the design of placing the power input port 23 on the non-gravity-bearing surface ensures the vertical stability of the substrate 1 while allowing the circuit module to obtain power via the shortest path, effectively reducing the wire crossing problems caused by the separation of the power module and the circuit board in traditional solutions. Compared with existing technologies, this design reduces system complexity through structural reuse, allowing modular circuit toys to maintain the same functionality. Simultaneously, the integrated power supply design avoids frequent plugging and unplugging of external power modules, improving the continuity and safety of the experimental process.

[0036] In a further optimized embodiment, the power connector 23 is located on the top surface of the support base 2 and close to the bottom of the substrate 1. This technical solution, by positioning the power connector 23 on the top surface of the support base 2 and near the bottom of the substrate 1, allows the circuit modules connected to the substrate 1 to complete the power supply connection with the shortest straight-line distance. The vertical spatial arrangement eliminates the need for lateral routing of the power lines, directly utilizing the three-dimensional space between the substrate 1 and the support base 2 to optimize wiring. The resulting technical effects include: reduced power line length and significantly improved wiring clutter; reduced line impedance and improved power supply stability due to the shortened power supply path; and simplified power connection procedures during modular assembly, improving user operating efficiency.

[0037] Furthermore, a battery compartment is provided inside the support base 2, and a removable cover 25 is provided on the surface of the support base 2 for sealing the battery compartment. Specifically, the battery compartment is constructed to accommodate standard-sized dry cell batteries or rechargeable battery packs, and spring contacts or magnetic electrodes can be installed inside to achieve stable electrical connection of the batteries. The battery compartment adopts a parallel dual-slot design, supporting the simultaneous installation of two AA batteries to increase power supply capacity. The removable cover 25 can be implemented in the following ways: first, by using a sliding rail structure, the cover 25 slides laterally to open and close along the guide groove on the side of the support base 2; second, by using a rotating shaft structure, the cover 25 can be opened and closed by a hinge at 90 degrees; third, by using a magnetic adsorption assembly, the cover 25 is aligned and fixed to the base by magnets. In this way, the working principle of this technical solution is that by integrating the power storage unit inside the support base 2, the space occupied by the external power module is directly reduced, making the overall layout of the circuit system more compact. The design of the removable cover 25 allows for battery replacement without disassembling the entire support base 2 structure; power maintenance can be completed simply by opening a portion of the maintenance channel.

[0038] Example 2:

[0039] This embodiment proposes a circuit experiment toy, including the vertical circuit board described in Embodiment 1. This solution introduces the vertical circuit board as the core component, utilizing its vertically oriented substrate 1 structure and supporting base 2 to achieve a three-dimensional layout. The standardized interlocking structure 11 on the surface of the substrate 1 allows for rapid installation and disassembly of circuit modules via mechanical interlocking, while the supporting base 2 provides a gravity-bearing surface 21 to ensure system stability. This solution reduces the desktop footprint through its three-dimensional architecture, while the standardized interface design avoids the layout chaos caused by horizontal layouts. By integrating the vertical mounting characteristics and modular connection mechanism of the vertical circuit board, the circuit experiment toy achieves spatial compactness and improved operational intuitiveness, effectively overcoming the inherent defects of planar layouts.

[0040] In a further embodiment, when the support base 2 is constructed as a power module, a circuit module is connected to the surface of the substrate 1 via a standardized mating structure 11. This circuit module is connected to the power outlet 23 via a power cord for power supply. Thus, this technical solution integrates the power supply function into the support base 2, placing the power interface near the circuit module mounting area, significantly shortening the power supply line length. The vertical orientation of the substrate 1 and the support base 2 forms a three-dimensional layout, optimizing space utilization. The standardized mating structure 11 enables quick assembly and disassembly of modules and reliable connection, while the gravity-bearing surface 21 of the support base 2 ensures system stability. Compared to existing planar layouts, this design eliminates the need for wire connections between independent power modules, reduces wiring clutter through physical integration, maintains the flexibility of modular connections, and forms a compact and scalable three-dimensional circuit system architecture.
