Description

Technical Field

[0001] This utility model relates to the field of toy products, specifically to an integrated building block. Background Technology

[0002] Currently, most building block toy light sets on the market consist of three parts: building blocks, a battery compartment, and an expansion board. These components are independent of each other, especially the battery compartment and expansion board, which need to be configured separately during use. While this design meets the basic functional requirements of building block toys, it also exposes some obvious problems.

[0003] Regarding the product's appearance, because the battery box and expansion board are separate components, they cannot be well integrated into the overall structure of the building block toy. This separate design not only affects the aesthetics of the building blocks but also appears somewhat abrupt and lacks harmony and unity during assembly, failing to meet users' high standards for appearance. Secondly, from the perspective of ease of use, building block toys are often assembled from numerous small parts, resulting in a large finished product that is not easy to move. When users need to move or rearrange them, the separate nature of the battery box and expansion board makes them inconvenient to carry and may even affect the user experience.

[0004] Furthermore, this combination of a separate battery box and expansion board increases costs. The wiring connecting the battery box and expansion board is more complex, prone to wiring tangles, increasing the product's failure rate and placing higher demands on after-sales service, thus raising the product's final cost. At the same time, the exposed expansion board lacks protection, making it susceptible to external factors and posing potential safety hazards, which could lead to the burning or damage of the light assembly and expansion board, affecting the overall lifespan.

[0005] In summary, the existing design of separating the battery box and expansion board in building block toys suffers from problems such as insufficient aesthetics, poor convenience, high cost, and low safety. Therefore, the market urgently needs a new type of building block. Utility Model Content

[0027] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0028] In this embodiment of the utility model, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use.

[0029] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0030] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0031] Furthermore, terms like "roughly" and "basically" are used to indicate that the content does not require absolute precision, but rather allows for a certain degree of deviation. For example, "roughly equal" does not simply mean absolute equality; in actual production and operation, achieving absolute "equality" is difficult, and a certain degree of deviation is generally present. Therefore, besides absolute equality, "roughly equal to" also includes the aforementioned situation where a certain degree of deviation exists. Using this as an example, in other cases, unless otherwise specified, terms like "roughly" and "basically" have similar meanings.

[0032] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Please refer to Figure 1 This embodiment provides an integrated building block, which includes a battery box 10 assembled from an upper outer shell 101 and a lower outer shell 102. The battery box 10 has matching insertion protrusions 103 and insertion recesses 104 on its outer surfaces at the upper and lower ends, respectively. The battery box 10 has a cavity inside, in which a power storage module 30 and an expansion board 20 are disposed. The power storage module 30 has a power supply interface 201 on the outer surface of the battery box 10 through the expansion board 20, which is used to connect with other power modules and supply power to the corresponding power modules.

[0034] Preferred, such as Figure 2The interlocking protrusions 103 and interlocking recesses 104 are designed according to standard building block specifications. The upper shell of the battery box 10 includes 12 cylindrical protrusions with a diameter of 5mm on the top, while the lower shell includes 5 circular recesses with a diameter of 6.7mm. These protrusions and recesses adopt standardized dimensions and distribution. The upper shell 101 and lower shell 102 precisely mate through these structures, allowing the battery box 10 to not only be stably assembled together but also compatible with other building block modules. Users can use the battery box 10 as a standard building block, assembling it in different positions in large building block structures. In a multi-layered building block model, the user places the battery box 10 at the bottom of the building. The protrusion design at the top allows the battery box 10 to serve as a supporting foundation, tightly integrated with the upper building block modules, preventing loosening due to model weight or shaking. This embodiment ensures the stability and compatibility of the battery box 10 in various structures, improving the reliability of building block assembly.

[0035] In another possible implementation, to improve the stability of the stacking assembly, the protrusions and grooves of the battery box 10 undergo a special friction treatment. Micro-textures are added to the inner sides of the protruding cylinders and grooves, creating greater friction between the two parts during assembly, thus ensuring a tighter and more stable structure. This treatment ensures that the battery box 10 will not easily detach from other modules, even under frequent movement. For example, in building mechanized block models, the battery box 10 serves as a power supply module connected to the robotic arm and sensor module. The reinforced friction protrusions and grooves ensure that the battery box 10 does not loosen due to vibration during the robotic arm's movement. This design is particularly suitable for block model scenarios requiring frequent handling or transportation, enhancing the module's safety and stability.

[0036] In another possible implementation, the protrusions and recesses of the battery box 10 are designed as a snap-fit ​​structure. The protrusions have small recessed insertion points at their tops, while the recesses have protruding snap-fit ​​edges. When the upper and lower outer shells 102 are assembled, the recessed insertion points and the snap-fit ​​edges of the recesses tightly engage, making it difficult to separate the two shells after assembly. This design not only enhances the stability of the assembly but also provides users with a convenient solution for disassembly and assembly. In outdoor display scenarios, after users assemble the battery box 10 with other building blocks, the stability of the snap-fit ​​structure eliminates concerns about accidental separation due to wind or external forces. This snap-fit ​​assembly design not only improves the robustness of the assembly but also facilitates the disassembly and assembly of modules when needed, making it suitable for use in various environments.

[0037] In another possible implementation, the protrusions of the battery box 10 are made of a flexible material, giving them a degree of elasticity during assembly. When the user assembles the battery box 10 with other modules, the flexible protrusions can adapt to slight angle changes, making assembly more flexible and preventing breakage or damage caused by slight misalignment or external force. This flexible design ensures a smooth experience during the building block assembly process and reduces the risk of damage from misoperation. When assembling complex building block models, users can use the flexible protrusions of the battery box 10 to achieve stable connections between multiple modules and flexibly adjust the module positions as needed without damaging the overall structure. This design is suitable for building more complex building block models, ensuring easy operation and stable connections during installation and adjustment.

[0038] In another possible implementation, the battery box 10 features not only recesses at the bottom but also auxiliary recesses around its sides, allowing for multi-directional splicing. Users can connect the battery box 10 to other building blocks from either side, creating more flexible structures. Each recess is designed with a standard 6.7mm diameter, ensuring a consistent match with the top protrusions and maintaining a stable structural effect regardless of the splicing direction.

[0039] When building horizontally or vertically extended block models, users connect the battery box 10 to the side module. Through the multi-directional grooves, the battery box 10 not only provides power but also serves as a structural support module, increasing the model's versatility and flexibility. This multi-directional connection design enhances the assembly flexibility of the block model, allowing users to freely construct complex structures according to their needs.

[0040] Preferably, a power supply circuit is provided between the energy storage module 30 and the expansion board 20.

[0041] In this embodiment of the invention, in the design of the battery box 10 of the integrated expansion board 20, the energy storage module 30 is typically preferably a lithium battery because of its high energy density, small size, and light weight, making it very suitable for applications in building block toys. However, depending on the needs of different application scenarios, the energy storage module 30 may also use other types of batteries to meet specific usage requirements or enhance the functionality and durability of the product.

[0042] 1) Lithium-ion batteries: Lithium-ion batteries are currently the most widely used battery type, featuring high energy density and long cycle life, making them suitable for building block applications requiring stable power supply over extended periods. Lithium-ion batteries can be quickly charged via a Type-C interface, offering high charging efficiency and ease of use. Furthermore, their lightweight nature matches the assembly requirements of building blocks, allowing users to easily integrate the battery box 10 into the building block structure. Lithium-ion batteries also have a certain degree of temperature control capability, which can be combined with temperature protection circuits to prevent safety issues caused by overheating. They are suitable for building block assembly scenarios requiring long battery life and lightweight construction, meeting most everyday application needs.

[0043] 2) Nickel-Metal Hydride (NiMH) Batteries: For applications requiring higher safety or cost control, the energy storage module 30 can utilize nickel-metal hydride (NiMH) batteries. Compared to lithium-ion batteries, NiMH batteries offer higher safety, relatively lower prices, and better environmental performance. Therefore, NiMH batteries are a preferred option for some budget-conscious or child-oriented building block products. While NiMH batteries have a lower capacity than lithium-ion batteries, they offer advantages in temperature adaptability and cycle life. NiMH batteries are less susceptible to damage from overcharging or over-discharging and can be used without the need for temperature control protection circuitry, thus simplifying the internal circuitry of the battery box 10 and reducing costs.

[0044] 3) Supercapacitors: In applications that emphasize rapid charging and discharging, supercapacitors can be considered as energy storage modules. Supercapacitors offer extremely high power density and fast charging capabilities, making them ideal for scenarios requiring high power output in short periods. For example, when building a small electric car model using blocks, a supercapacitor can provide high power output to the electric motor in a short time, enabling rapid acceleration and braking. Furthermore, supercapacitors charge extremely quickly, fully charging in minutes, significantly reducing waiting time. Although supercapacitors have lower energy density and shorter battery life than lithium batteries, they excel in scenarios requiring frequent charging and high power output, making them suitable for highly interactive, high-frequency block projects.

[0045] 4) Disposable Batteries (e.g., alkaline batteries): In certain applications, the battery box 10 can be designed using disposable alkaline batteries, particularly suitable for scenarios where frequent use is not required or power demand is low. For example, when the building block battery box 10 is used for display models or short-term exhibition projects, alkaline batteries can provide stable power support and can be directly replaced after use, making operation simple. Furthermore, disposable batteries eliminate the need for charging interface 202 and circuit design, simplifying the structure of the battery box 10 and reducing costs. In some outdoor activities, short-term exhibitions, or educational demonstrations, alkaline batteries are an economical and convenient option to meet temporary power supply needs.

[0046] 5) Solar Panels: For outdoor building block projects or applications emphasizing environmental protection, the battery box 10 can integrate small solar panels as energy storage modules 30. The solar panels convert solar energy into electrical energy through the photovoltaic effect and store it inside the battery box 10, making them suitable for use in sunny environments. For example, when the building block project is used for outdoor display, the solar panels can provide continuous power to the building block modules, reducing reliance on the charging interface 202. Although solar cells have lower power output and longer charging times, they are an ideal choice for environments with long-term power needs and inconvenient charging conditions.

[0047] 6) Replaceable Battery Module: To enhance the flexibility and adaptability of the modular battery box 10, a replaceable battery module can be designed, supporting the insertion and replacement of various battery types such as lithium batteries, nickel-metal hydride batteries, and supercapacitors. Users can choose the appropriate battery module according to their actual needs. For example, lithium batteries can be selected for long battery life in daily use, while a supercapacitor module can be used for short-term projects with high power requirements. This replaceable design makes the modular battery box 10 more widely applicable, meeting a variety of different power demand scenarios.

[0048] Furthermore, in the design of the battery box 10 of the integrated expansion board 20, the core function of the power supply circuit is to ensure efficient power transfer between the energy storage module 30 and the expansion board 20, providing a stable output to power external devices such as light sets or other electronic modules. The power supply circuit not only supports basic power supply but can also optimize power supply performance, improve energy efficiency, and enhance user experience through various circuit design schemes. The most basic power supply circuit design directly connects the lithium battery and the expansion board 20 with two wires. The positive and negative terminals of the lithium battery are connected to the power supply ports on the expansion board 20, respectively. This design is simple and reliable, ensuring that external modules can directly obtain stable power from the lithium battery. This circuit is suitable for scenarios with low power supply requirements and simple power supply modes, meeting the power needs of general building block toy modules.

[0049] In another possible implementation, to increase circuit flexibility, a bidirectional power supply circuit can be designed, allowing the lithium battery to both power external modules via the expansion board 20 and be charged via the expansion board 20. For example, after the Type-C charging port 202 is connected to an external power source, the circuit directs external current into the lithium battery to achieve energy storage. After charging is complete, the circuit automatically switches back to power supply mode. This bidirectional circuit design ensures the ease of use of the battery box 10, allowing users to switch between charging and power supply without disassembling the battery box 10.

[0050] In another possible implementation, in some modular applications, different electronic modules may require different voltages to operate. In this case, a voltage regulation function can be added to the power supply circuit. Through a voltage regulator, the battery's output voltage can be adjusted to meet the requirements of a specific module. For example, a light assembly may require 5V, while some small motors may require 3.3V. This design allows for flexible adaptation to various external modules. In practical use, users can select the desired voltage using a toggle switch or adjustment knob on the expansion board 20, greatly increasing the applicability of the battery box 10.

[0051] In another possible implementation, incorporating a load detection function into the power supply circuit can further enhance the intelligence and power supply efficiency of the modular battery box 10. This circuit can detect the size of the connected load and automatically adjust the output power according to different load conditions. For example, when a low-power device (such as a small LED light) is detected, the circuit reduces the output power to minimize unnecessary power consumption; while when a high-power device (such as a small motor) is detected, the output power is automatically increased to ensure normal operation of the device. This load-detection power supply circuit dynamically adapts to different power demands, improving battery efficiency and battery life.

[0052] In another possible implementation, to support the simultaneous use of multiple modules, a distributed power supply circuit can be designed. This involves providing multiple independent power supply interfaces 201 on the expansion board 20, each with its own power path and switch control. This design ensures that users can connect multiple modules simultaneously, each receiving independent power without interference. For example, three power supply interfaces 201 can be designed to control the connected LED, sensor, and motor respectively. With distributed power supply, users can flexibly control the switch of each circuit as needed, enabling multi-module combination and avoiding the impact of a power outage on other modules.

[0053] In another possible implementation, to enhance the user experience, the power supply circuit can incorporate an automatic switching function. This means that when the lithium battery level drops below a set value, it automatically switches to standby mode to prevent external modules from malfunctioning due to insufficient power. For example, when the battery level is detected to be below 20%, the power supply circuit automatically cuts off external power and illuminates indicator light 107 to remind the user to charge. This automatic power switching circuit ensures safety while extending battery life, making the battery box 10 more intelligent.

[0054] Preferably, the upper outer shell 101 and the lower outer shell 102 are respectively provided with screw posts facing each other, which are used to fix the upper outer shell 101 and the lower outer shell 102 after they are spliced ​​together by screws.

[0055] In this embodiment of the invention, the upper outer shell 101 and the lower outer shell 102 are each provided with one or more opposing screw posts, allowing the user to secure the upper and lower outer shells 102 with screws. The screws, connected by the screw posts, firmly lock the shells in place, ensuring the stability of the battery box 10 during use. This design is suitable for most common building block assembly applications, effectively preventing the battery box 10 from loosening during assembly and movement, thus improving the overall stability of the building block module. The advantages of the standard screw fixing method are its simple structure and convenient assembly, meeting the basic needs of most users.

[0056] In another possible implementation, where higher stability is required, a multi-screw distributed fixing scheme can be employed. Screw posts are located at the four corners of both the upper outer shell 101 and the lower outer shell 102, and the shells are secured with four screws. This design significantly increases the robustness of the shell connections and is suitable for larger, more complex modular units, especially in scenarios requiring higher-intensity assembly and movement. For example, when the modular battery box 10 serves as a central support module, multi-screw fixing effectively prevents shell separation due to load or improper operation. This distributed design also enhances the impact resistance of the modular battery box 10, ensuring its stability during frequent assembly and disassembly.

[0057] In another possible implementation, to improve accuracy during assembly, locating pins can be introduced in addition to screw fixing. Located next to the screw post, the locating pins are inserted into the locating holes of the upper and lower housings 102 to ensure alignment of the two parts. The combination of locating pins and screws enables more precise installation, avoiding misalignment caused by screw slippage. For example, in applications requiring rapid installation, the locating pin design can reduce human error, ensuring efficient and accurate installation. This combination is particularly suitable for mass production scenarios, improving not only assembly efficiency but also product consistency and precision.

[0058] In another possible implementation, to improve the user's installation experience, a snap-fit ​​auxiliary fixing structure can be designed in addition to screw fixation. Interlocking snap-fit ​​structures are designed on the edges of the upper shell 101 and the lower shell 102, allowing the upper and lower shells 102 to be secured first with snap-fits and then reinforced with screws during assembly. Snap-fit ​​fixing not only facilitates quick assembly for users but also enhances assembly stability, ensuring that the shells will not easily detach even if the screws loosen. For example, this design can simplify the installation process and improve safety in children's building block toys. This combined fixing structure is more suitable for scenarios requiring frequent disassembly and assembly, extending the product's lifespan.

[0059] In another possible implementation, in scenarios requiring long-term fixation and where frequent disassembly and assembly are inconvenient, adhesive can be used for auxiliary fixation on top of screws. The adhesive can be applied around the screw post to enhance the adhesion between the screw and the housing, thereby further increasing the structural robustness. For example, in outdoor block display scenarios, adhesive-assisted fixation can effectively prevent screws from loosening due to environmental changes or vibrations, ensuring long-term stability. This design is suitable for scenarios that do not require repeated disassembly and assembly, and performs particularly well in outdoor environments, resisting external forces such as wind and rain.

[0060] In another possible implementation, a detachable nut fixing structure can be designed to facilitate subsequent maintenance and replacement. By adding a nut to the upper end of the screw post, the user can remove or replace the upper and lower outer shells 102 at any time as needed, increasing the flexibility of the modular battery box 10. For example, when it is necessary to replace the battery module or clean the interior, the detachable nut structure allows the upper and lower outer shells 102 to be opened quickly, facilitating user maintenance. This design is suitable for scenarios requiring periodic maintenance and provides a more convenient user experience.

[0061] Preferably, the surface of the expansion plate 20 is further provided with an opening for a light sensor 105; a light sensor 105 is disposed in the opening for the light sensor 105, and the light sensor 105 serves as a trigger for a photosensitive switch; the photosensitive switch is disposed on the expansion plate 20 and is used to control the on / off state of the power supply interface 201.

[0062] Preferably, the surface of the expansion plate 20 is also provided with a toggle switch outlet; a switch cap is provided in the toggle switch outlet, and the switch cap can be toggled along the toggle switch outlet to trigger the manual switch 106; the manual switch 106 is provided on the expansion plate 20 and is used to cooperate with the photosensitive switch to control the on / off state of the power supply interface 201.

[0063] Preferably, the switching states of the manual switch 106 include at least manual on, manual off, and automatic; when the manual switch 106 is in the manual on state, the power supply interface 201 is normally open; when the manual switch 106 is in the manual off state, the power supply interface 201 is normally closed; when the manual switch 106 is in the automatic state, the switching state of the power supply interface 201 is triggered by a photosensitive switch.

[0064] In this integrated modular design, the surface of the expansion board 20 integrates a light sensor 105 opening, a toggle switch outlet, and multiple switch control methods, enabling the battery box 10 to automatically control the on / off state of the power supply interface 201 according to external light conditions, greatly improving user convenience and intelligence. The following is a detailed description of each embodiment, demonstrating the specific implementation and functional effects of different control modes in various application scenarios.

[0065] Example 1: Light sensor 105 controls automatic on / off mode.

[0066] In this embodiment, a light sensor 105 is provided on the surface of the expansion board 20, and the light sensor 105 is built into it. The light sensor 105 acts as a trigger for a photosensitive switch. When the intensity of ambient light changes, the light sensor 105 automatically adjusts the on / off state of the power supply interface 201. Specifically, when the ambient light is strong (such as during the day or in an environment with artificial light), the light sensor 105 triggers the photosensitive switch to cut off the power supply interface 201, preventing the battery box 10 from supplying power to unnecessary modules, thereby achieving a power-saving effect. When the ambient light weakens (such as at night or in a dark room), the light sensor 105 automatically triggers the photosensitive switch to turn on the power supply interface 201, supplying power to the lighting module in the building block toy.

[0067] This automatic on / off design allows the battery box 10 to autonomously control its power supply according to environmental changes, achieving intelligent lighting effects without manual operation. For example, when building a house or city model, the battery box 10 can automatically control the lighting module, turning the model on at night and turning it off during the day, increasing the model's fun and interactivity.

[0068] Example 2: Control by combining manual switch 106 with photosensitive switch.

[0069] In this embodiment, the expansion board 20 not only has a light sensor 105, but also a toggle switch outlet with a switch cap inside. The user can manually slide the switch cap to control the on / off state of the power supply interface 201. The manual switch 106 is designed to be used in combination with the photosensitive switch. By manually controlling the priority setting, the user can more flexibly select the operating mode of the battery box 10.

[0070] Specifically, when the manual switch 106 is in the "manual on" state, the power supply interface 201 is always on, and even if the light sensor 105 detects light, the power supply interface 201 will not automatically turn off; when the manual switch 106 is in the "manual off" state, the power supply interface 201 is always off and is not affected by the light sensor 105; when the manual switch 106 is in the "automatic" state, the state of the power supply interface 201 is controlled by the photosensitive switch to achieve an automated switching effect.

[0071] For example, when the user sets the manual switch 106 to "manual on," it ensures that the lighting module is continuously powered in specific display or shooting scenarios, avoiding power outages due to changes in light. When set to "manual off," it is suitable for scenarios requiring energy saving, allowing the user to directly and manually turn off the power to the battery box 10, preventing unnecessary power consumption. This combination of manual and automatic control design increases the user's autonomy and control flexibility.

[0072] Example 3: Multi-position manual switch 106 control.

[0073] This embodiment adds multiple control levels to the manual switch 106, including five states: "manual on", "manual off", "automatic", "low brightness", and "high brightness". In addition to the basic manual on / off and automatic control, users can also switch between the "low brightness" and "high brightness" levels as needed to adjust the brightness of the lamp group connected to the power supply interface 201.

[0074] In this design, the "low brightness" setting reduces the output power of the power interface 201, suitable for nighttime or scenarios requiring a soft atmosphere; the "high brightness" setting provides full power output, suitable for scenarios with higher lighting needs. This multi-level manual switch 106 mode allows users to flexibly adjust the brightness to meet different requirements. For example, in a child's bedroom nightlight setup, the block light group can be adjusted to a low brightness mode to provide a warm and soft light source; while in model display, it can be switched to a high brightness mode to make model details more clearly visible. This design further enhances the practicality and user experience of the block battery box 10.

[0075] Example 4: Control using a combination of timer and photosensitive switch.

[0076] This embodiment introduces a timer function, which, in conjunction with a photosensitive switch, allows the battery box 10 to enable or disable the power supply interface 201 within a specific time period. Specifically, the user can preset the power supply period, for example, between 6 PM and 10 PM, during which the light sensor 105 will automatically control the power supply interface 201 to be on or off based on the light intensity; outside the set time, the power supply interface 201 remains off regardless of the light intensity.

[0077] This design, combining a timer and a photosensitive switch, is suitable for scenarios with periodic lighting needs. For example, in a model exhibition hall, users can preset the power supply time so that the lights automatically turn on during the exhibition and turn off afterward, saving energy and reducing maintenance costs. This timing control not only enhances the automation level of the battery box 10 but also gives it greater application value in specific commercial scenarios.

[0078] Example 5: Motion sensing control.

[0079] In this embodiment, a motion sensor is also added to the expansion board 20, which, together with the photosensitive switch, controls the power supply interface 201. The motion sensor can detect external movement or vibration and trigger the power supply interface 201 when detected. This function is mainly used in highly interactive block-building scenarios to ensure that the block model only lights up when someone approaches or touches it, thus improving the interactive effect.

[0080] For example, in demonstrations of building block assembly, the model only lights up when someone approaches, effectively reducing power consumption while showcasing the model. For children's toy applications, the introduction of motion sensors allows the building block modules to automatically light up when a child approaches, providing a more engaging play experience. This design further enriches the functionality of the battery box 10, enabling it to adapt to more dynamic usage environments.

[0081] Preferably, the expansion plate 20 also has a charging hole on its surface; the charging hole is provided with a charging interface 202 connected to the energy storage module 30, which is used to charge the energy storage module 30 when the charging module is connected to the charging interface 202 while it is energized.

[0082] In this embodiment of the invention, an expansion board 20 is provided with a Type-C interface socket. This interface is connected to the internal lithium battery via two wires for charging the battery box 10. The Type-C interface is designed to be installed on the right edge of the battery box 10 and exposed through the charging hole in the outer shell. Users only need to insert the Type-C charging cable into the interface to charge the battery inside the battery box 10. The Type-C interface supports bidirectional charging technology, resulting in higher charging efficiency. It is also compatible with various standard charging cables and power adapters to meet users' charging needs in different environments. This Type-C interface charging design features high versatility and fast charging, making it particularly suitable for the use of everyday building block toys. With this design, users can charge the battery box 10 at home or outdoors using common Type-C charging cables without the need for dedicated charging equipment, increasing the portability and ease of use of the battery box 10.

[0083] In another possible implementation, a wireless charging module is installed on the back of the expansion board 20, compatible with mainstream wireless charging protocols such as the Qi standard. When the user places the battery box 10 on the wireless charging base, the wireless charging module automatically docks with the base to charge the internal lithium battery. This design eliminates the need for users to plug and unplug charging cables, greatly improving the user experience. Simultaneously, the wireless charging design reduces wear and tear on the battery box 10's interface, extending the device's lifespan. This wireless charging solution is ideal for building block modules that require frequent charging, especially in exhibition scenarios. When the battery box 10 is placed for extended periods, it can be continuously charged via the wireless charging base, ensuring the continuity of the exhibition effect. For example, in a building block-themed exhibition, the wireless charging base can be hidden under the display stand, keeping the displayed building block models constantly charged without manual intervention.

[0084] In another possible implementation, a magnetic charging interface 202 is embedded within the charging port of the expansion board 20. The end of the charging cable is also magnetic; the user simply brings the cable close to the charging port, and the interface automatically attaches and connects, enabling quick and convenient charging. The magnetic charging interface 202 features a foolproof design, allowing users to adjust its orientation freely without precise alignment; charging begins immediately. Furthermore, the magnetic design prevents the interface from loosening when the user pulls on the cable, effectively protecting the integrity of the charging interface 202. This magnetic charging design is particularly suitable for children's building block toys. Children may not be able to accurately insert traditional charging cables while playing, but the magnetic design helps them easily complete the charging operation, improving ease of use and preventing damage to the device in case of accidental pulling. This design extends the device's lifespan and enhances the safety of the battery box 10.

[0085] In another possible implementation, a small solar panel is mounted on the surface of the extension plate 20 and connected to the energy storage module 30, enabling it to directly charge the internal battery using sunlight. The solar panel is exposed on the upper part of the battery box 10 and can be charged using natural light in outdoor environments. During charging, the battery box 10 does not require a power cord; simply placing it in a well-lit area will allow the solar panel to continuously charge the internal energy storage module 30. This solar charging interface 202 design is ideal for outdoor building block applications. For example, during outdoor activities, the battery box 10 can provide sustainable power to building block light sets, sensors, and other modules without worrying about running out of power. This design is not only environmentally friendly but also reduces dependence on external power sources, making it a suitable charging method for outdoor and low-power-consumption applications.

[0086] In another possible implementation, the charging port of the expansion board 20 embeds a Micro-USB interface, which connects to the internal battery. Micro-USB, a common charging interface 202, allows users to use non-Type-C charging cables for emergency charging in special circumstances. This design primarily considers the compatibility requirements of the battery box 10 under specific conditions, addressing unexpected scenarios where a Type-C charging cable is unavailable. This emergency charging design is suitable for scenarios involving building blocks used for extended periods. For example, during long-term outdoor displays, if the Type-C cable fails or is lost, users can still use the Micro-USB cable to charge the battery box 10, ensuring its continuous power supply. This design enhances the versatility of the battery box 10, adapting to various usage scenarios.

[0087] In another possible implementation, the expansion board 20 has both Type-C and Micro-USB interfaces on its surface. The Type-C interface is used for fast charging, while the Micro-USB interface serves as a backup charging method. When the Type-C interface is inserted, the system defaults to charging via the Type-C interface. When the Type-C interface is not inserted, the Micro-USB interface can be used as an emergency charging port. This dual-interface design provides users with more charging options, ensuring that the battery box 10 can be charged promptly in any scenario. This dual-interface charging design improves the charging adaptability of the battery box 10. In specific situations, users can select the appropriate charging interface 202 based on available conditions, such as in different environments like the office, home, and outdoors, to meet their charging needs. This design flexibility makes the battery box 10 more adaptable, reduces reliance on specific charging cables, and allows users to charge the battery box 10 anytime, anywhere.

[0088] In another possible implementation, the charging interface 202 on the expansion board 20 is equipped with an intelligent management module. This module can detect charging voltage and current and adjust the charging speed according to the battery level. When the battery level is low, the intelligent management module will speed up the charging process; when the battery is about to be fully charged, the charging speed will automatically slow down to protect the battery and prevent overcharging. The intelligent management module can also monitor the charging temperature. If the temperature is too high, the system will automatically stop charging to avoid safety issues caused by overheating. The intelligent charging interface 202 management design is suitable for scenarios involving long-term use, ensuring extended battery life. For example, when charging overnight, the user can connect the battery box 10 to a power source, and the intelligent management module will automatically control the charging progress to ensure the battery is fully charged under safe conditions. This design not only improves charging efficiency but also enhances charging safety, making it suitable for users with high requirements for battery life.

[0089] Preferably, the surface of the expansion plate 20 is also provided with an indicator light 107 hole; an indicator light 107 is provided in the indicator light 107 hole, and the indicator light 107 is used to indicate whether the power storage module 30 is in a charging state by means of its on / off state.

[0090] In this embodiment of the utility model, in the design of the battery box 10 of the modular integrated expansion board 20, a dedicated indicator light 107 hole is also opened on the surface of the expansion board 20. The indicator light 107 is embedded therein to display the charging status of the energy storage module 30. The indicator light 107 will display different on / off states according to the charging status of the battery box 10, so that the user can know the charging status of the battery in real time. This design not only simplifies the user's judgment of the charging process, but also increases the operability of the battery box 10 and the user experience. The indicator light 107 informs the user whether the battery is charging through simple on / off changes. When the battery box 10 is connected to the charger and the energy storage module 30 is charging, the indicator light 107 lights up, intuitively reminding the user that the charging process is in progress; when the battery is fully charged, the indicator light 107 turns off, indicating to the user that charging is complete, avoiding overcharging. This design is especially suitable for users who are concerned about the battery status, making the battery box 10 more convenient and safer to use. Users do not need to check the charging device every time; they only need to observe the status of the indicator light 107 to know whether charging is complete.

[0091] Based on this utility model, users can directly view the battery charging progress without opening the battery box 10 or any additional devices, improving ease of use. The indicator light 107 not only allows users to effectively manage charging time and avoid battery damage caused by prolonged charger connection, but also enhances the safety and reliability of the device. At the same time, this intuitive status display method makes the battery box 10 more user-friendly and convenient for use in various scenarios, especially suitable for children's building block toys, displaying building block models, and other similar applications.

[0092] Preferably, the power supply interface 201 is provided with one or more; the power supply interface 201 is a piercing terminal female interface.

[0093] Preferably, the surface of the expansion plate 20 is also provided with at least one power supply interface 201 hole; each power supply interface 201 extends out of the surface of the battery box 10 based on the power supply interface 201 hole.

[0094] In the embodiments of this utility model, such as Figure 3The expansion board 20 features nine 2P 0.8mm piercing terminal female connectors on its surface. Each power supply connector 201 is connected to the battery module via an independent power supply line. These nine connectors are evenly distributed around the expansion board 20 and extend from the surface of the battery box 10 through the holes in the power supply connectors 201, allowing users to easily connect multiple modules, such as LED lights, motors, and sensors. This design allows for simultaneous power supply to multiple modules while maintaining a compact interface and ease of operation. In model demonstrations, users can connect multiple light groups through the nine power supply connectors 201 to provide uniform lighting for different areas of a large architectural model, creating a more realistic effect. This design also allows users to adjust the number and position of modules according to their needs. For example, when building a small robot, the nine power supply connectors 201 can be connected to wheel motors, sensors, and control modules respectively, enabling more flexible functional combinations.

[0095] In another possible implementation, the power supply interfaces 201 on the surface of the expansion board 20 are designed as three groups, each group containing three 2P 0.8mm piercing terminal female interfaces. Each group of interfaces is powered independently, and the power supply status of each group of interfaces can be switched by toggling a switch or control button, allowing the user to flexibly control the operation of multiple modules. Each group of power supply interfaces 201 extends out of the surface of the battery box 10 through the power supply interface 201 hole and is distributed on different sides to reduce the crossing of power supply lines. This grouped power supply interface 201 design is particularly suitable for scenarios with zoned control. For example, in a multi-functional building block vehicle model, the first group of interfaces can connect to the headlights and taillights, the second group of interfaces is used to connect to the control system, and the third group of interfaces connects to the sensor module. The user can control the power supply status of each module according to needs, avoiding unnecessary power consumption. This grouped control method improves the battery's range while making the building block model more versatile and practical.

[0096] In another possible implementation, the expansion board 20 features only a single piercing terminal female connector, but with a high power supply capacity, specifically designed to provide high-power output for modules requiring significant power. The connector is located in the center of the expansion board 20 and is connected to the battery module via a thickened power supply line to ensure stable high-power output. This single-interface high-power supply design is suitable for scenarios requiring the driving of large components or high-power accessories. For example, when building a large robotic arm model, this high-power supply connector 201 is connected to the main motor, providing sufficient power to drive the robotic arm's operation. The high-power design ensures smooth motor operation and prevents performance degradation due to insufficient power. This embodiment simplifies the number of power supply connectors 201, improves the output performance of a single connector, and enables the battery box 10 to support power-intensive modules.

[0097] In another possible implementation, the expansion board 20 features a dual-row power supply interface matrix 201, consisting of 16 2P 0.8mm pierced terminal female connectors arranged in a 4x4 matrix. Each interface independently connects to a battery module, evenly distributed across two rows on the expansion board 20. This dual-row design reduces interference between interfaces, ensuring stable power output across all interfaces. This matrix interface design is suitable for scenarios requiring multi-point power supply in block-based building models. For example, in a city scene, users can connect the power supply interfaces 201 to different modules such as buildings, streetlights, and vehicles, easily providing lighting and power support for multiple areas. This design not only enriches the expressiveness of the scene but also reduces the clutter of power lines through the even distribution of the dual-row matrix structure, facilitating user management.

[0098] In another possible implementation, the expansion board 20 features a ring-shaped power supply interface 201, consisting of 12 2P 0.8mm piercing terminal female connectors arranged in a circle, evenly distributed around the edge of the expansion board 20. This ring-shaped interface design allows users to connect multiple modules around the battery box 10, ensuring balanced power supply to each module through the ring arrangement. This ring-shaped power supply interface 201 design is suitable for scenarios requiring symmetrical power supply, such as when building circular or ring-shaped block models. Users can connect lighting modules to each interface to achieve uniform lighting throughout the model. For example, evenly spaced lights on the exterior walls of a block castle, connected via the ring-shaped power supply interface 201, create a more immersive atmosphere.

[0099] In another possible implementation, the expansion board 20 is designed with various power supply interfaces 201. Besides the standard 2P 0.8mm pierced terminal female connector, it also includes 4P and 6P interfaces to support modules with different power requirements. The 2P interface is used for low-power modules, such as LED lights; the 4P interface supports medium-power devices, such as small sensors; and the 6P interface provides stable power to high-power devices. This combined multi-specification interface design is suitable for complex block model scenarios. Users can select different interface specifications according to their needs and allocate power reasonably. For example, in a multi-functional car model, the 2P interface is used to power the headlights, the 4P interface provides power to the sensor module, and the 6P interface is connected to the main drive motor to ensure the car's driving force. This multi-specification interface design enhances the functional diversity of the block model while improving the compatibility of the battery box 10, allowing users to flexibly combine different configurations.

[0100] In another possible implementation, the power supply interface 201 not only supports power output but also enables charging via bidirectional power supply, allowing power to be input from an external power supply device to the energy storage module 30 inside the battery box 10. The bidirectional power supply interface 201 is located on the top of the expansion board 20. When the user connects the battery box 10 to an external power source, power is supplied to the energy storage module 30 through the interface; when no external power source is connected, the interface automatically switches to output mode to power other modules. This bidirectional power supply interface 201 design is suitable for scenarios where the battery box 10 requires frequent charging. For example, in a temporary demonstration of building block assembly, the user can directly connect the battery box 10 to an external power source via the bidirectional interface to maintain continuous charging and ensure uninterrupted power supply during the demonstration. This design improves the efficiency of the power supply interface 201 and facilitates user management of the power source.
