Description

A smart glowing Rubik's Cube Priority application

[0001] This application claims priority to Chinese invention patent application filed on December 11, 2024 [Application No.: 2024118252621] [Title: A Smart Illuminated Rubik's Cube and Its Control Method], which is incorporated herein by reference in its entirety. Technical Field

[0002] This invention relates to the field of Rubik's Cube technology, specifically to a color-changing intelligent light-emitting Rubik's Cube. Background Technology

[0003] The Rubik's Cube, a type of puzzle, originated in the 1970s and is a globally popular educational toy. It's a large cube made up of multiple smaller cubes that can be rotated in any direction to match the colors of the faces. This is called solving the Rubik's Cube, specifically matching the colors of the visible faces. A Rubik's Cube typically has N×N cells forming its faces, with a typical 3×3 cube, but 2×2, 4×4, 5×5, and 7×7 cubes also exist. Recently, the 3×3×3 cube has become very popular, even hosting a world championship and being widely used in children's education.

[0004] With the development of technology, the Rubik's Cube has evolved from a mechanical cube to an electronic one, combining with electronic technology to create various variants such as glowing cubes and smart cubes. Most existing electronic Rubik's Cubes connect to mobile phones or computers via sensors to capture the cube's state, assist in solving it, or allow for online play against others. Glowing cubes, in particular, have light-emitting devices installed inside each cell to display a color, and the color of these devices changes with touch, eliminating the need for direct hand rotation. This type of cube uses sensors to detect the direction of the user's touch and controls the color of the light-emitting devices accordingly, allowing for solution even without direct hand rotation.

[0005] For example, patent application CN105641919A discloses an electronic Rubik's Cube, which includes a fixed cube frame. Each face consists of nine colorful units, and each colorful unit comprises a button and a colored light emitter. An electronic chip receives button signals, recognizes corresponding user operations, and controls different colorful units to display different colors and play corresponding animations, thus simulating a Rubik's Cube. This invention also discloses two different electronic Rubik's Cube control methods. Based on these methods, user behavior is recognized, and corresponding colorful units are controlled to simulate a Rubik's Cube. The Rubik's Cube is controlled by an electronic chip, connects to an app via Bluetooth, accepts user configuration, and uses different methods to control the cube according to the configuration. Through electronic technology, the Rubik's Cube can be transformed into complex, irregularly shaped cubes, enabling a variety of educational games and bringing more fun.

[0006] For example, the invention patent with publication number CN108786096B discloses an intelligent Rubik's Cube and its operation method, which can restore the Rubik's Cube by changing the light of various colors through the light-emitting part. An embodiment of the intelligent Rubik's Cube according to the present invention includes: a cubic shell, each face of which is divided into N×N units; a light-emitting part formed inside each of the units, emitting at least one light through the surface of the unit to the outside; six rotating members, formed to freely rotate around a rotation axis penetrating the center of each face; a rotation detection unit, which detects the rotation direction and rotation angle of each of the six rotating members according to their respective rotation; and a control unit, which controls the light-emitting part to change and emit light according to a preset rule in accordance with the rotation direction and rotation angle detected by the rotation detection unit, causing the light of the edge units of the face formed by the rotating members and the units of the other four faces adjacent to the edge units.

[0007] However, none of the aforementioned electronic Rubik's Cubes can be mechanically rotated; that is, the individual cubes cannot be rotated. They only use color changes of light-emitting elements to create various patterns. This inability to manually rotate the cube, relying solely on color changes to create patterns, defeats the fundamental purpose of the Rubik's Cube for experienced players, especially advanced players. It's similar to how the prevalence of e-books has freed people from the constraints of paper books, yet many still prefer the habit or preference of manually flipping through physical books.

[0008] Therefore, a smart illuminated Rubik's Cube has emerged on the market that can achieve both mechanical rotation and "one-click scrambling" through color changes of its light-emitting elements. For example, patent application CN113476820A discloses a 3x3 Rubik's Cube that can control the displayed colors. The cube includes a central control module, a central power supply module, 6 center pieces, 12 edge pieces, and 8 corner pieces. After receiving external color display commands, the central control module adjusts the colors of the center pieces and transmits synchronized commands via infrared pulses generated by infrared emitters to the second communication modules in the edge pieces and the third communication modules in the corner pieces. The corner and edge pieces then display the corresponding colors upon receiving the commands. The key point is to simulate the physical rotation effect of a traditional Rubik's Cube by changing the colors of each face of the cube.

[0009] However, these glowing Rubik's Cubes all face a problem: when the size of the Rubik's Cube becomes smaller, it is easy to form a noticeable light spot in a certain area of ​​the glowing surface, while other areas are darker. In other words, the glowing surface presents a clear boundary between light and dark and two different areas of light and dark. Summary of the Invention

[0010] The purpose of this invention is to provide an intelligent light-emitting cube that partially solves or alleviates the above-mentioned shortcomings of the prior art, namely, it can avoid the formation of light spots on the light-emitting surface or greatly reduce the brightness or coverage of the light spots.

[0011] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0012] A smart luminous Rubik's Cube includes a core module, cube blocks rotatably connected to the core module, and a charging system disposed between the cube blocks. Each cube block includes a center block, corner blocks, and edge blocks. The center block is located at the center point of each cube face, the corner blocks are located at the four corner points of each cube face, and the edge blocks are located between adjacent corner blocks. Each corner block and edge block contains a light-emitting device, a main control circuit board for controlling the light-emitting devices, and a wireless communication module. Each corner block and edge block includes a light-emitting surface and a non-light-emitting surface, and at least one light-emitting device is disposed corresponding to each light-emitting surface. The light-emitting devices in the corner blocks are all disposed on the same main control circuit board, and the light-emitting devices in the edge blocks are all disposed on the same main control circuit board. The main control circuit board divides the interior of each corner block or edge block into a light-emitting cavity and a non-light-emitting cavity. Each light-emitting cavity has corner brackets that divide it into several light-emitting sub-cavities, the number of which is equal to the number of light-emitting surfaces.

[0013] In some embodiments, the charging system employs a contact charging system, specifically comprising: corner block charging pins disposed on the non-light-emitting surface of the corner block, the corner block charging pins being electrically connected to the main control circuit board of the corner block; edge block charging pins disposed on the non-light-emitting surface of the edge block, the edge block charging pins being electrically connected to the main control circuit board of the edge block and electrically contacting the corner block charging pins; a third charging pin disposed in the core module for connecting an external charging device; when the intelligent light-emitting cube is connected to an external charging device, at least one edge block charging pin on the edge block is electrically contacting the first charging pin of the charging device; and the third charging pin of the central control module within the core module is electrically contacting the second charging pin of the charging device.

[0014] In some embodiments, the corner block includes three luminous surfaces and three non-luminous surfaces, and the edge block includes two luminous surfaces and four non-luminous surfaces.

[0015] In some embodiments, the prism includes a cavity for accommodating the main control circuit board. The main control circuit board of the prism is inclinedly disposed in the cavity, and the cavity is divided into a light-emitting cavity and a non-light-emitting cavity. The bottom of the corner abuts against the upper surface of the main control circuit board, thereby dividing the light-emitting cavity into light-emitting sub-cavities corresponding to two light-emitting surfaces respectively, and multiple light-emitting devices on the main control circuit board are respectively located in the two light-emitting sub-cavities.

[0016] In some embodiments, the cavity is cuboid in shape, and in a cross-section, the corner is located on the first diagonal of the cavity, the main control circuit board in the edge block is located on the second diagonal of the cavity, or parallel to the second diagonal, and the main control circuit board is perpendicular to the corner.

[0017] In some embodiments, the corner block includes a cavity, and the main control circuit board of the corner block is inclinedly disposed in the cavity, dividing the cavity into a light-emitting cavity and a non-light-emitting cavity. The bottom of the corner block abuts against the upper surface of the main control circuit board, thereby dividing the light-emitting cavity into light-emitting sub-cavities corresponding to three light-emitting surfaces respectively, and multiple light-emitting devices on the main control circuit board are respectively located in the three light-emitting sub-cavities.

[0018] In some embodiments, the smart light-emitting cube further includes an energy storage element disposed in the non-light-emitting cavity, the energy storage element being electrically connected to the main control circuit board.

[0019] In some embodiments, the corner blocks include three, and each of the three edges connected in the corner blocks extends toward the main control circuit board and is connected to form a corner block.

[0020] In some embodiments, the cavity is cuboid in shape, and in a cross-section, the main control circuit board in the corner block is parallel to the third diagonal of the cavity and perpendicular to the corner.

[0021] In some embodiments, magnetic elements are provided on the three non-light-emitting surfaces of the corner block, and magnetic elements are provided on the two opposite non-light-emitting surfaces of the four non-light-emitting surfaces of the edge block; and / or an elastic reset member is provided in the center block.

[0022] Beneficial Effects: Since electronic cubes contain numerous electronic components, and each cube piece is an independent unit, achieving both mechanical rotation and control over the color and / or brightness of the light-emitting devices presents a significant challenge in terms of electrical connections and stability between the cube pieces. This invention's intelligent light-emitting cube, by equipping each cube's light-emitting surface with a corresponding light-emitting device and wireless communication module, and designing a contact charging system, allows for not only manual mechanical rotation but also the creation of various patterns by controlling the color and / or brightness changes of the light-emitting devices on each surface. This achieves a fusion of mechanical and light-emitting cube design.

[0023] Furthermore, for some smaller illuminated Rubik's Cubes (e.g., toy Rubik's Cubes for young children), due to their small size, the internal cavity of each cube piece is small. If a circuit board is arranged parallel to each luminous surface, on the one hand, the distance between the luminous device on the circuit board and the luminous surface is too close, resulting in a strong light spot on the luminous surface; on the other hand, more electronic components need to be installed inside, increasing the difficulty of assembly. Therefore, in some embodiments of the present invention, at least one luminous device is provided for each luminous surface of the luminous block, and the luminous devices of each luminous block (e.g., corner piece, or edge piece) are all set on the same main control circuit board (in this text, the same circuit board can be multiple boards connected together in various ways, for example, each luminous device is mounted on a circuit board and connected together through various lines to form a circuit board that can divide the internal space of the edge or corner piece into luminous cavities and non-luminous cavities; or multiple luminous devices can be arranged on a single circuit board that divides the internal space of the edge or corner piece into luminous cavities and non-luminous cavities, or...). This invention involves placing multiple light-emitting devices on the same circuit board, while other devices are placed on other circuit boards. These are then connected by wiring to form a circuit board that divides the internal space of a block or corner piece into light-emitting cavities and non-light-emitting cavities. In other words, whether it's a single unit or separate but interconnected units, as long as the block's interior is ultimately divided into light-emitting and non-light-emitting cavities, it belongs to the same circuit board. The main control circuit board divides the interior of the light-emitting block into light-emitting and non-light-emitting cavities. Each light-emitting cavity has corner brackets that further divide it into several sub-cavities, the number of which equals the number of light-emitting surfaces. This invention uses multiple light-emitting devices (such as LED beads) placed on a single circuit board, angled within the cavities, and corner brackets to divide the cavities, creating independent light-emitting areas. This avoids the problem of light spots caused by the light-emitting devices being too close to the light-emitting surfaces, and also reduces the difficulty of processing and assembly, thus lowering costs. Furthermore, the main control circuit board divides the cavity into a light-emitting cavity and a non-light-emitting cavity, allowing other functional components, such as a battery, to be added to the non-light-emitting cavity, thereby ensuring the battery life of the light-emitting module.

[0024] Furthermore, in some embodiments of the present invention, the corner piece includes three light-emitting surfaces and three non-light-emitting surfaces, the edge piece includes two light-emitting surfaces and four non-light-emitting surfaces, magnetic elements are provided on the three non-light-emitting surfaces of the corner piece, and magnetic elements are provided on the two relatively left and right non-light-emitting surfaces of the four non-light-emitting surfaces of the edge piece. As a result, the corner piece can be attracted and approached by the edge pieces corresponding to its three non-light-emitting surfaces through the magnetic elements, and then the corner piece and the edge piece are closely adhered together to ensure the stability of the Rubik's Cube. Moreover, it ensures that the charging pins between the corner piece and the edge piece, for example, the contacts, can be more accurately aligned, and also makes the electrical contact between the two more stable. On the other hand, it also enables the positioning and correction of the Rubik's Cube after twisting, optimizing the feel.

[0025] Furthermore, in some embodiments of the present invention, an elastic resetting member is provided inside the center piece, which can enrich the user experience and improve the user experience.

[0026] Furthermore, in some embodiments of the present invention, the center piece also has a light-emitting function. Specifically, a light-emitting device, a main control circuit board for controlling the light-emitting device, and a wireless communication module are provided inside the center piece; the contact charging system further includes: a center charging pin, such as a touch plate, provided on the non-light-emitting surface of the center piece, the center charging pin is electrically connected to the main control circuit board of the center piece, and the center charging pin is in electrical contact with the edge piece charging pin; an electrical contact pin (i.e., a charging pin) provided in the core module and in electrical contact with the main control circuit board of the center piece; when the intelligent light-emitting Rubik's Cube is externally connected to a charging device, the electrical contact pin in the core module is in electrical contact with the second charging pin of the charging device.

[0027] Furthermore, the charging device配套 with the intelligent light-emitting Rubik's Cube of the present invention includes a base, a charging main body provided inside the base, and a first charging pin and a second charging pin provided on the charging main body. The second charging pin can be inserted into the core module through a through hole provided on any center piece and is in electrical contact with the third charging pin inside the core module. Even further, the second charging pin can also be inserted into the core module through a through hole provided on any center piece and is in electrical contact with the electrical contact pin inside the core module.

[0028] Furthermore, in some embodiments of the present invention, an electric energy storage element (such as a battery / capacitor) is provided inside the Rubik's Cube piece for electric energy storage, serving as a power supply module or a power module, increasing the overall battery life of the Rubik's Cube. Specifically, this electric energy storage element is provided in a non-light-emitting cavity and is electrically connected to the corresponding main control circuit board.

[0029] Convenient charging and uniform power distribution: The charging method employed in this invention not only saves users charging time but also ensures uniform power distribution across all pieces through contact charging. This helps extend the lifespan of the Rubik's Cube, reduces problems caused by battery aging and uneven use, and improves product sustainability.

[0030] The use of a light-diffusing panel optimizes light efficiency: It eliminates glare and harsh light, making the light emitted by the LEDs softer and more uniform. This not only provides a more comfortable visual experience but also reduces eye discomfort, especially during prolonged use. The optimized light-diffusing panel improves the product's usability and user-friendliness.

[0031] Rich interactive features: The application of this invention not only provides color control, but also includes other functions such as timed shutdown, brightness adjustment, and Rubik's Cube solving guidance. These features not only increase the product's practicality, but also provide users with more ways to interact, enhancing the product's diversity and appeal.

[0032] In summary, the innovative technology of this invention offers significant advantages and beneficial effects in several aspects, including improved user experience, increased product appeal, extended product lifespan, and more ways to entertain and interact. These advantages and beneficial effects enable the smart cube of this invention to better meet the needs of modern consumers for smart products, providing them with more creative and customizable educational toys.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] In this document, suffixes such as "module," "component," or "unit" used to denote elements are used solely for the purpose of illustrative purposes and have no specific meaning in themselves. Therefore, "module," "component," or "unit" can be used interchangeably. In this document, terms such as "upper," "lower," "inner," "outer," "front," "rear," "one end," and "the other end," indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In this document, unless otherwise expressly specified and limited, terms such as "installed," "equipped with," and "connected" should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; it can be a connection within two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. In this document, "and / or" includes any and all combinations of one or more of the listed related items. "Multiple" in this document means two or more, i.e., it includes two, three, four, five, etc.

[0038] In this article, "lighting effect" or "illumination effect" refers to the different patterns presented by all light-emitting devices, such as LEDs, in all the Rubik's Cube blocks. To construct different patterns using the Rubik's Cube blocks, some LEDs need to be lit, some LEDs need to be off, or all LEDs need to be lit or all LEDs need to be off, or the colors and / or brightness of the LEDs lit at different positions need to be different. In this article, "light-emitting block" refers to a Rubik's Cube block that has built-in light-emitting devices and can emit light, such as the edge blocks and corner blocks in subsequent embodiments; and the center blocks, edge blocks, and corner blocks in other subsequent embodiments.

[0039] The present invention provides an intelligent light-emitting Rubik's Cube, comprising a core module 23a and cube blocks. The cube blocks include a non-light-emitting center block 9a and light-emitting blocks, each light-emitting block including corner blocks 6a and edge blocks 2a, and a contact charging system disposed between the cube blocks. Each light-emitting block (i.e., corner block 6a and edge block 2a) contains a light-emitting device 25a (such as an LED bead), an integrated circuit (i.e., a main control circuit board) for controlling the LED bead, a rechargeable battery (i.e., an energy storage element or power module), and a wireless communication module (e.g., a Bluetooth module).

[0040] The present invention also provides another intelligent light-emitting Rubik's Cube, including a core module 23a and cube blocks. The cube blocks include light-emitting blocks, which include a light-emitting center block 9a, corner blocks 6a and edge blocks 2a, as well as a contact charging system disposed between the cube blocks. Each light-emitting block contains a light-emitting device 25a (such as an LED bead), an integrated circuit (i.e., a main control circuit board) for controlling the LED bead, a rechargeable battery (i.e., an energy storage element or power module), and a wireless communication module (e.g., a Bluetooth module).

[0041] The core module 23a includes a central control module 24a and a wireless communication module. The central control module 24a can communicate wirelessly with the main control circuit board (including the second main control circuit for corner pieces and the third main control circuit for edge pieces) in each illuminated cube, and also with a cube assistant (also known as an AI assistant). For example, the central control module 24a receives control commands from the cube assistant and forwards them to each cube through the wireless communication module, or it can synchronously upload the cube's state (e.g., the rotation angle of corner or edge pieces) to the cube assistant. This allows the color of each LED to be controlled via the cube assistant (e.g., a mobile application, or a remote controller independent of the phone and cube settings).

[0042] In some embodiments, the wireless communication module is a Bluetooth chip. The integrated circuit within each illuminated cube controls the LED light emission based on control commands received from the central control module 24a within the core module, according to its Bluetooth chip. This control includes adjusting color, brightness, and luminous efficacy. Other wireless communication technologies can also be used, such as Wi-Fi, Zigbee, LoRa, or infrared communication, to meet different connectivity needs. Wi-Fi connectivity provides wider range of connectivity, suitable for homes or offices. Zigbee and LoRa are suitable for low-power, long-range communication, ideal for remote monitoring or IoT applications. Infrared communication consists of an infrared light transmitter and receiver, transmitting core commands via infrared light.

[0043] In some embodiments, to make the light emitted by the LED beads softer and more uniform, thereby avoiding light spots in certain locations or reducing the brightness or coverage of light spots, each light-emitting surface of the Rubik's Cube is equipped with a light-diffusing plate, which can prevent direct light and excessive concentration, providing users with a more comfortable visual experience. Preferably, the outer shell of all Rubik's Cubes is made of high-quality plastic material to ensure the stability and durability of the Rubik's Cube during use.

[0044] Core Module 23a (e.g., ball-axis core): A core module 23a is located at the center of the smart illuminated cube. This core module 23a includes a housing, a central control module 24a located within the housing cavity, and a rotating shaft 3a located on each of the six faces of the cube on the housing. Each center block 9a is rotatably connected to the rotating shaft 3a. The central control module 24a has a third charging pin for connecting an external charging device 26a. For cubes where the center block 9a is illuminated, the rotating shaft 3a also has an electrical contact that is electrically connected to the central control module 24a, and the other end of the electrical contact is electrically connected to the main control circuit board within the center block 9a. This allows the power module (e.g., a second battery) within the center block 9a to be connected to a charger or charging base via the rotating shaft 3a for charging. For cubes where the center block 9a is not illuminated, the rotating shaft 3a does not have any electrical contacts, meaning that no power is needed to supply power to the center block 9a.

[0045] Preferably, the core module 23a includes a spherical shell (e.g., an upper hemispherical shell 5a and a lower hemispherical shell 4a; of course, a shell of other shapes such as square or rectangular may also be used instead of a spherical shell). Multiple pivots 3a on the spherical shell are rotatably connected to the center piece 9a of each face of the Rubik's Cube. Furthermore, a central control module 24a is provided inside the spherical shell (as shown in Figures 10 and 11). The central control module 24a is provided with charging pins of an external charging device 26a.

[0046] To reduce the complexity of the contact charging system, electrical contacts can be omitted from the rotating shaft. The core module 23a directly contacts the second charging pin 7b in the charger or charging base via the charging pin on the central control module 24a, i.e., the non-illuminated center block 9a is not charged. The edge block 2a is charged directly via its edge block charging pin, i.e., the edge block contact 2b (see Figures 3A and 3B), to the first charging pin contact 6b of the charger or charging base. The corner block 6a is charged via its corner block charging pin, i.e., the corner block contact plate 1b (see Figures 6A, 6B, and 6C), to the edge block contact 2b on the edge block 2a. The corner block contact plate 1b serves as a female connector, and the edge block contact 2b serves as a male connector.

[0047] More preferably, an encoder is installed inside the rotating shaft to record the rotation angle of the center block, etc., and the central control module 24a stores, records and analyzes the data and sends it to the background system (such as a server).

[0048] In some embodiments, the core module 23a is located in the center of the smart illuminated Rubik's Cube, and the Bluetooth chip inside it (i.e., the central control module 24a and the wireless communication module are integrated into one unit) acts as the main control core of the Rubik's Cube, responsible for communicating with Rubik's Cube assistants such as mobile applications, receiving instructions sent by the Rubik's Cube assistants and distributing them to other Rubik's Cube blocks. Preferably, the central control module 24a within the core module 23a efficiently manages the communication between the various Rubik's Cube blocks, realizing coordinated and synchronized operation of functions.

[0049] Center block 9a: Typically, center block 9a rotates frequently during rotation, but its position remains unchanged. Therefore, a light-emitting device 25a can be installed inside center block 9a, or alternatively, no light-emitting device 25a or other electronic components may be installed inside it. Preferably, to improve the user's feel and enhance the user experience, an elastic reset element, such as a spring 10a, is provided at the end of the rotating shaft near center block 9a, as shown in Figure 2.

[0050] Corner Block 6a: Each corner block 6a includes three light-emitting surfaces and incorporates an integrated circuit (i.e., a second main control circuit) and a Bluetooth chip (i.e., a wireless communication module). These components are responsible for generating the light-emitting effect and communicating with the central control module 24a within the core module 23a. Furthermore, each light-emitting surface corresponds to at least one light-emitting device, such as an LED bead.

Furthermore, each light-emitting surface corresponds to at least one light-emitting device, such as an LED bead.

[0052] Preferably, the integrated circuit has important functions within each Rubik's Cube, including controlling LED beads, handling Bluetooth communication, and assisting in realizing user-customized lighting effects. Furthermore, it communicates with each Rubik's Cube via Bluetooth to enable collaborative operation of the product.

[0053] The interoperability of these circuits is crucial, enabling the blocks to work together to achieve functions such as user-defined settings, color control, and brightness adjustment.

[0054] Contact charging system: For a Rubik's Cube where all pieces are lit, current can be transmitted to all pieces through the contact charging system when the central control module 24a is charging; while for a Rubik's Cube where the center piece is not lit but the corner and edge pieces are lit, current can be transmitted to all corner pieces 6a and all edge pieces 2a through the contact charging system when the central control module 24a is charging, providing power to the electronic components in the entire Rubik's Cube.

[0055] Power source (i.e., energy storage element): Preferably, a supercapacitor or renewable energy source is used. Supercapacitors have high-speed charging and discharging capabilities, which can increase the product's lifespan. Renewable energy sources such as solar energy or kinetic energy devices can provide a sustainable power source for the cube, reducing reliance on conventional batteries and improving sustainability.

[0056] Light-emitting device 25a: Preferably, the light-emitting device is an RGB LED, a full-color LED, a programmable LED, or a higher brightness LED. Full-color LEDs can display more colors and effects, programmable LEDs allow users to customize the lighting mode, and higher brightness LEDs can provide brighter light effects. These options enrich the product's lighting effects and color performance.

[0059] Example 1: Referring to Figures 1-5, this is a schematic diagram of the structure of an intelligent light-emitting Rubik's Cube according to the present invention. Specifically, the intelligent light-emitting Rubik's Cube includes: a core module 23a, a center block 9a, a corner block 6a, and an edge block 2a, as well as a contact charging system.

[0060] Referring to Figure 2, in this embodiment, the core module 23a includes a spherical shell and a rotating shaft 3a corresponding to the central block 9a of the six faces. The spherical shell contains a central control module 24a, a power module, and a wireless communication module (such as a Bluetooth communication module: Bluetooth SoC).

[0061] Referring to Figure 2, in this embodiment, the central block 9a is enclosed by the central base 8b and the central cover 8a to form a cavity, and the rotating shaft 3a of the core module 23a extends into the cavity. The rotating shaft 3a can rotate relative to the central block 9a, or the central block 9a can rotate on the rotating shaft 3a. Furthermore, in order to enhance the user experience, such as the tactile feel of the user pressing, the portion of the rotating shaft 3a extending into the cavity is fitted with an elastic element, and its end is provided with a spring fixing block 11a. That is, the elastic element (e.g., spring 10a) is located between the spring fixing block 11a and the inner wall of the central base 8b.

[0062] In some embodiments, the central base 8b of the central block 9a and the central block 8a may be integrally molded or detachably connected together.

[0063] Referring to Figures 6A and 6B, in this embodiment, the corner block 6a includes: three light-emitting surfaces, a second power supply module (such as corner block battery 17a), a second control circuit (i.e., a main control circuit board, such as corner block main control circuit board 16a), and a second wireless communication module, as well as three LED lights (i.e., light-emitting devices 25a) corresponding to the three light-emitting surfaces respectively. The second control circuit is electrically connected to the second power supply module, which supplies power to the second control circuit, the LED lights, and the second wireless communication module. In some embodiments, the corner block contact plate 1b is mounted on the corner block housing 6a and is electrically connected to the corner block main control circuit board 16a via corresponding lines. In other embodiments, to reduce production costs and complexity, referring to Figure 6C, the corner block contact plate 1b is directly integrated onto the corner block main control circuit board 16a. Specifically, the corner block contact plate 1b is electrically connected to the corner block main control circuit board 16a via a connecting plate 27. Preferably, the connecting plate 27 is L-shaped (in this text, L-shaped means that the shape of the component is generally L-shaped, for example, it includes two connected parts, and the axes of the two parts are not necessarily perpendicular to each other, but at a certain angle, such as the obtuse angle shown in Figure 6C, so that when the corner block main control circuit board 16a is installed, the part that is inclined relative to the corner block main control circuit board 16a can adapt to the inclination of the corner block shell, so that the corner block contact plate 1b at the end of the inclined part can pass through the mounting hole for mounting the corner block contact plate 1b pre-set on the corner block shell), one end of which is electrically connected to the corner block main control circuit board 16a, and the other end is electrically connected to the corner block contact plate 1b. Correspondingly, the corner block shell 6a is provided with mounting holes for mounting the corner block contact plate 1b, and when installed, the contact surface on the corner block contact plate 1b for contacting the edge block contact point 2b is flush with or slightly protrudes from the outer wall surface of the corner block shell 6a.

[0064] Referring to Figures 3A to 5, in this embodiment, the prism block 2a includes: two light-emitting surfaces, a third power supply circuit (such as the prism block battery 15a), a third control circuit (i.e., a main control circuit board, such as the prism block main control circuit board 13a), and a third wireless communication module, as well as two LED lights (i.e. light-emitting devices 25a) corresponding to the two light-emitting surfaces respectively. The third control circuit is electrically connected to the third power supply module, and the third power supply module is used to supply power to the third control circuit, the LED lights, and the third wireless communication module.

[0065] In this embodiment, the light-emitting area is divided in the cavities of corner block 6a and edge block 2a by corner bracket 20a (e.g., a reflector made of reflective material), which provides support and increases structural strength while realizing multiple color gamuts in the same cavity.

[0066] Specifically, referring to Figures 3A to 5, the edge block 2a includes a cuboid cavity (the cuboid in this text includes shapes close to or approximately cuboids). An edge block main control circuit board 13a is obliquely disposed within this cuboid cavity, dividing the cavity into a light-emitting cavity and a non-light-emitting cavity 22a. A retaining corner 20a is also provided within the cavity, with its bottom abutting against the upper surface of the edge block main control circuit board 13a (preferably, the retaining corner 20a is perpendicularly connected to the edge block main control circuit board 13a, see Figure 4; perpendicularly in this text means that the center line or extension direction of the retaining corner is perpendicular to the plane containing the edge block main control circuit board 13a), thereby dividing the light-emitting cavity into light-emitting sub-cavities 21a corresponding to the two light-emitting surfaces. Two light-emitting devices 25a on the edge block main control circuit board 13a are located within the two light-emitting sub-cavities, respectively. The third control circuit and the third wireless communication module are both integrated on the edge block main control circuit board 13a. The non-light-emitting cavity 22a refers to a cavity in which no light-emitting device is installed. A third power supply circuit (such as the edge block battery 15a) is located within this non-light-emitting cavity 22a, thereby supplying power to the edge block main control circuit board 13a and the light-emitting device 25a, improving the Rubik's Cube's battery life. Of course, this cavity can also adopt other shapes. Preferably, the edge block main control circuit board 13a and the corner 20a are located on or parallel to two diagonals of the cross-section of the cuboid cavity. More preferably, the two light-emitting devices 25a are located in the central area of ​​the circuit board 13a and close to the corner 20a. Even more preferably, referring to Figure 5, a through hole is provided on the corner 20a near the light-emitting device 25a, thereby connecting the two light-emitting sub-cavities 21a.

[0067] More preferably, the main control circuit board 13a of the prism block is rectangular (rectangle in this document includes shapes that are close to or approximately rectangular) (its four corners are chamfered for easy installation and replacement). The corner 20a is located on the first diagonal O1 of the cross-section of the rectangular cavity shown in Figure 4, while the main control circuit board 13a of the prism block is parallel to and located below the second diagonal O2 of the cross-section of the rectangular cavity shown in Figure 4. This makes the spatial size of the light-emitting cavity larger than the spatial size of the non-light-emitting cavity 22a, thereby increasing the distance between the light-emitting device and the light-emitting surface, so as to eliminate light spots to a certain extent and ensure uniform light. At the same time, the non-light-emitting cavity 22a is set to place the battery-powered lamp energy storage element, thereby improving the battery life of each light-emitting block.

[0068] Typically, for larger illuminated Rubik's Cubes, a circuit board containing the light-emitting device can be placed parallel to each illuminated face of the cube. However, for smaller illuminated Rubik's Cubes (e.g., toy cubes for younger players), the smaller size results in smaller internal cavities for each cube. Therefore, placing a circuit board parallel to each illuminated face would have two problems: firstly, the distance between the light-emitting device on the circuit board and the illuminated face would be too close, resulting in a strong light spot on the illuminated face; secondly, it would require more electronic components inside, increasing the difficulty of assembly.

[0069] In view of this, in this embodiment, two light-emitting devices 25a (such as LED beads) are set on a prism block main control circuit board 13a, and the prism block main control circuit board 13a is tilted in the cavity. At the same time, a corner 20a is set to divide the cavity and separate the light-emitting area. On the one hand, this avoids the light-emitting device 25a from being too close to the light-emitting surface and causing light spots. On the other hand, it also reduces the difficulty of processing and assembly and reduces costs.

[0070] Similarly, for corner block 6a, referring to Figures 6A-8, corner block 6a includes a cavity in which a corner block main control circuit board 16a is inclinedly arranged to divide the rectangular cavity into a light-emitting cavity and a non-light-emitting cavity 22a. A corner bracket 20a is also provided in the rectangular cavity. The bottom of the corner bracket 20a abuts against the upper surface of the corner block main control circuit board 16a (preferably, the corner bracket 20a is perpendicular to the corner block main control circuit board 16a; in this article, perpendicular means that the center line or extension direction of the corner bracket 20a is perpendicular to the plane where the corner block main control circuit board 16a is located), thereby dividing the light-emitting cavity into light-emitting sub-cavities 21a corresponding to the three light-emitting surfaces respectively, and the three light-emitting devices 25a on the corner block main control circuit board 16a are located in the three light-emitting sub-cavities respectively. That is, three light-emitting devices 25a (such as LED beads) are set on a corner block main control circuit board 16a, and the corner block main control circuit board 16a is tilted and set in the cavity. At the same time, three connected corner brackets 20a (or reflectors) are set to divide the cavity, separating three light-emitting sub-cavities 21a. Preferably, the three light-emitting sub-cavities are of uniform size.

[0071] Referring to Figures 8 and 9, in this embodiment, given the limited space within the cube's internal cavity, the corner block's main control circuit board 16a adopts a hexagonal structure to maximize the area occupied by the circuit board integrating multiple electronic components. Furthermore, when placed within the corner block's cavity, it ensures sufficient space for the battery while allowing the light-emitting devices 25a to be positioned as far away from the light-emitting surface as possible, thereby reducing the formation or coverage of light spots and ensuring uniform light distribution. Preferably, the three light-emitting devices 25a, the second control circuit, and the second wireless communication module are all integrated onto the corner block's main control circuit board 16a.

[0072] Preferably, referring to Figure 6A, the hexagonal corner block main control circuit board 16a includes three short sides 16a-1 and three long sides 16a-2, and the three short sides 16a-1 and three long sides 16a-2 are spaced apart, so that when it is installed in the rectangular cavity of the corner block, the two symmetrical short sides 16a-1 abut against two adjacent non-light-emitting surfaces, while the other short side 16a-1 abuts against a third non-light-emitting surface connected to the two non-light-emitting surfaces, so that a gap is formed between the two symmetrical long sides 16a-2 and the inner wall of the rectangular cavity, that is, the light-emitting cavity and the non-light-emitting cavity are not completely isolated, which is conducive to heat dissipation.

[0073] Furthermore, referring to Figures 7 and 8, the corner block main control circuit board 16a is parallel to the diagonal between any two light-emitting surfaces. More preferably, the corner block main control circuit board 16a is located below the third diagonal O3, thereby providing sufficient storage space for the battery while increasing the space of the light-emitting cavity. This results in a greater distance between the corner block main control circuit board 16a and the light-emitting surface, which helps to eliminate light spots while ensuring uniform light.

[0074] Preferably, the three light-emitting devices 25a are located in the central area of ​​the corner block main control circuit board 16a, which means that the light-emitting devices 25a are far from the light-emitting surface, which helps to eliminate light spots while ensuring uniform light. Preferably, the corner 20a is made of a material that can reflect light. Through the reflection of the corner 20a, the brightness of the light-emitting surface can be improved, which also helps to eliminate light spots.

[0075] In other embodiments, each edge piece 2a has two non-light-emitting surfaces with magnetic elements (such as magnets) arranged opposite each other, and each corner piece 6a also has three non-light-emitting surfaces with magnetic elements (such as magnets). This allows the corner piece 6a to be attracted to the edge piece 2a corresponding to its three non-light-emitting surfaces through magnetic elements, thereby ensuring the stability of the Rubik's Cube and ensuring the stability of the alignment of the charging pins between the edge piece 2a and the corner piece 6a and the electrical connection between the charging pins.

[0076] In this embodiment, each corner block 6a and edge block 2a can return status information (e.g., rotation angle), posture information, power information, etc. to the core module 23a through the corresponding second wireless communication module and third wireless communication module.

[0077] Of course, the Rubik's Cube Assistant (which can also use the same integrated Bluetooth + control chip structure) can simultaneously send corresponding control commands to different edge pieces 2a and different corner pieces 6a to perform one-to-many control.

[0078] In this embodiment, each illuminated cube is equipped with a separate battery / capacitor for energy storage, serving as a corresponding power supply module or power module, thereby increasing the overall battery life of the cube.

[0079] In this embodiment, referring to Figure 1, the above-mentioned contact charging system includes: a corner block contact plate 1b (i.e., corner block charging pin) disposed on the second sidewall of each corner block 6a that contacts the edge block 2a, and the corner block contact plate 1b (i.e., corner block charging pin) is electrically connected to the second main control circuit of the corner block 2a; an edge block contact 2b (i.e., edge block charging pin) disposed on the third sidewall of each edge block 2a that contacts the corner block 6a, the edge block contact 2b is electrically connected to the third main control circuit of the edge block 2a, and is electrically connected to the corner block contact plate 1b of the corner block 6a; it also includes a third charging pin (not shown) disposed in the core module 23a for an external charging device 26a; when the smart light-emitting cube is connected to an external charging device 26a, the third charging pin on the central control module 24a in the core module 23a is electrically connected to the second charging pin 7b of the charging device 26a, as shown in Figures 10 and 11. Therefore, in this embodiment, the core module 23a, corner block 6a, and edge block 2a are charged individually. The core module 23a is individually charged by connecting to the second charging pin 7b of the charging device 26a via the third charging pin in its built-in central control module 24a. The two edge blocks 2a on the same plane simultaneously make electrical contact with the first charging pin 4b of the charging device 26a via their respective edge block charging pins (i.e., edge block contacts 2b), and the charge is transferred to the corner block 6a in electrical contact with it (see Figures 12 and 13). Preferably, referring to Figures 12 and 13, in this embodiment, the charging device 26a includes a base, a charging body disposed within the base, and four conductive pins (i.e., second charging pins 7b) disposed on the charging body. The four conductive pins can be inserted into the core module 23a through through holes provided on any of the central blocks 9a and make electrical contact with the third charging pin of the central control module 24a within the core module 23a.

[0080] More preferably, referring to Figures 11 to 13, the charging device 24a further includes at least one metal plate (i.e., a first charging pin 6b). When the Rubik's Cube is placed on the base of the charger, the metal plate (i.e., the first charging pin 6b) can simultaneously make electrical contact with the edge contact points 2b on the sidewalls of the upper and lower edge pieces 2a on the same face, thereby charging the edge pieces 2a. Correspondingly, since the corner piece 6a makes electrical contact with the edge contact points 2b of the edge piece 2a through the corner contact plate 1b (wherein the corner contact plate 1b serves as a female connector and the edge contact point 2b serves as a male connector), during charging, the edge piece 2a provides current to the corner piece 6a through the corner contact plate 1b and the edge contact point 2b for charging. More preferably, four metal plates (serving as female connectors) are respectively provided corresponding to the four faces, so that the edge pieces 2a on the four faces can be charged simultaneously.

[0081] Referring to Figures 1, 3B, and 13, each edge block 2a has two opposing third sidewalls with edge block contacts 2b, which are electrically connected to corner block contacts 1b on the second sidewalls of the corner blocks 6a on both sides of the edge block 2a (each corner block 6a has three second sidewalls with corner block contacts 1b). This means that each edge block 2a simultaneously transmits power to two corner blocks 6a, and the same corner block 6a receives power from three edge blocks 2a simultaneously. Preferably, the edge block contact 2b includes a resettable spring, one end of which is connected to the edge block main control circuit board (or contact circuit board), and the other end is a free end with an electrical contact, as shown in Figure 3B. When no external force is applied, the electrical contact protrudes from the third sidewall of edge piece 2a under the action of the spring piece. When it is subjected to the force of corner contact plate 1b on corner piece 6a, the spring piece deforms, thereby driving the electrical contact to move inward into edge piece 2a. At the same time, under the elastic force of the spring piece, the electrical contact is pressed tightly against corner contact plate 1b, thereby transferring electrical power. Of course, in other embodiments, the charging system in the Rubik's Cube described above can also use other existing charging systems, which will not be elaborated here.

[0082] The following example illustrates the Rubik's Cube in this embodiment: The Rubik's Cube assistant sends instructions only to the central control module 24a (such as the central control circuit). After the central control module processes and analyzes the instructions, it sends them to the corner pieces and edge pieces via the first wireless communication module in a "one-to-many" manner. Corner pieces 6a and edge pieces 2a only receive instructions from the central control module within the core module 23a, and do not receive instructions from the Rubik's Cube assistant. The instruction contains encoded information identifying corner piece 6a or edge piece 2a, as well as action information. All corner pieces and edge pieces receive the instruction and determine whether the encoded information belongs to them. If it does, they will perform the corresponding action; otherwise, they will discard it. In other words, the Rubik's Cube assistant does not communicate directly with corner piece 6a or edge piece 2a; its control object is the central control module or the core module.

[0083] Preferably, the Rubik's Cube assistant can be a remote control device with a user interface. The appearance of this Rubik's Cube assistant replaces the role of the mobile phone and can prevent children from playing with the mobile phone instead of the Rubik's Cube itself.

[0084] The intelligent illuminated Rubik's Cube of this invention includes a teaching guidance mode and a practice training mode. The practice training mode allows users to experience different ways to play based on the same learning content, enriching the gameplay; it also helps solidify the learned content, guiding deeper thinking and facilitating a deeper understanding of the corresponding Rubik's Cube solving methods. Additionally, users can customize patterns through the Rubik's Cube assistant. Furthermore, it allows for the recording of the solving steps, enabling users to "replay" previous solving steps via lighting effects, thus recording and reviewing the solution. After connecting to the Rubik's Cube assistant, the solved steps can be exported and displayed with one click. Solutions shared by other users can also be imported, achieving one-click interoperability of solutions. Specifically, the recording can be performed by the Rubik's Cube's central control module, or the Rubik's Cube assistant can store the recorded content when the Rubik's Cube sends it back to the Rubik's Cube assistant, allowing the user to control the Rubik's Cube to "replay" the solution when replaying it through the assistant.

[0085] The following example, using the interaction between a smart illuminated Rubik's Cube and a Rubik's Cube assistant, illustrates the working principle of the smart illuminated Rubik's Cube: 1. Activate the Rubik's Cube assistant and connect it to the smart illuminated Rubik's Cube. The assistant allows you to customize the color, brightness, and lighting effect modes of the LEDs. 2. User commands are transmitted to the core module via Bluetooth. Upon receiving the commands, the core module distributes them to all corner pieces, edge pieces, and center pieces to adjust the working mode of the LEDs. 3. Within the corner pieces, center pieces, and edge pieces, their respective integrated circuits control the operation of the corresponding LEDs, producing different lighting effects based on the user-set parameters, including color changes and brightness adjustments. 4. A contact charging system ensures power transfer and charging between the cube pieces. Users only need to charge the core module and edge pieces simultaneously to charge all pieces, providing convenient charging. 5. Users can control the cube's lighting effects in real time through the application, and can also set functions such as timer shutdown and brightness adjustment. The Rubik's Cube assistant can also provide solving guidance, recording and analyzing user operations in real time to help users improve their solving skills.
