Description

Technical Field

[0001] This utility model relates to the field of children's educational electronic equipment technology, and in particular to a children's educational electronic toy. Background Technology

[0002] With the rapid development of children's educational toys, electronic interactive toys have gradually become important tools for improving children's logical thinking and hand-eye coordination. In existing technologies, toy devices based on light dot matrices mostly employ fixed LED arrays or simple touch feedback designs, such as triggering the brightness of a single light source via a button, or displaying a preset path on the screen for the user to imitate. However, such solutions have significant limitations: the interactive logic of traditional toys is mostly limited to discrete operations (such as independently lighting a single node), lacking dynamic feedback on the user's operation path, and making it difficult to intuitively represent logical connections (such as connecting lines, path continuity). In gameplay requiring path tracking (such as "one-stroke drawing" or "connect-the-dots"), existing technologies typically rely on physical connecting components (such as a magnetic pen and touch points) or virtual trajectories on the screen, resulting in complex device structures or a lack of realism from physical operations, and failing to map the logical relationships of user operations in real time through light effects. Furthermore, existing devices struggle to visually distinguish between multiple parallel paths, easily causing cognitive confusion for children in gameplay involving multiple problem-solving paths.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0004] In order to solve the above problems, the purpose of this utility model is to provide a children's educational electronic toy with the technical advantages of enhancing the intuitiveness of interactive logic, improving the visualization effect of path tracking, and realizing the differentiation of multi-path parallel operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This application provides a children's educational electronic toy device, the technical solution of which is as follows: It includes a main frame with a main control module inside; a matrix-type interactive device mounted on the main frame, comprising multiple switch units arranged in a rectangular array; each switch unit is embedded with a main indicator light source, and the multiple main indicator light sources form a first light spot matrix matching the switch unit array; auxiliary indicator light sources are provided in the gap area between two adjacent main indicator light sources, and the auxiliary indicator light sources are arranged at intervals along the row and column directions of the main indicator light sources to form a second light spot matrix; the main control module is electrically connected to a storage module, switch units, main indicator light sources, and auxiliary indicator light sources, and is configured to control the on / off state of the corresponding main indicator light source according to the trigger signal of the switch unit, used to characterize the activation state of the user operation node; when two adjacent main indicator light sources are detected to be lit simultaneously, the auxiliary indicator light source in the direction of the line connecting the two main indicator light sources is activated to form a continuous light path.

[0007] Furthermore, this application also proposes to include a storage module that is communicatively connected to the main control module. The storage module pre-stores an interactive question bank, and each question in the interactive question bank includes standard path parameters and question stem information. The main control module is further configured to illuminate part of the main indicator light source in the standard path on the first light spot matrix according to the question stem information of the interactive question bank. The user's solution path is compared with the question path parameters in the storage module, and the path matching degree is calculated.

[0008] Furthermore, this application also proposes that both the main indicator light source and the auxiliary indicator light source are constructed as RGB LEDs or combinations of LEDs capable of displaying two or more light colors.

[0009] Furthermore, this application also proposes that the main control module, storage module, switching unit, main indicator light source and auxiliary indicator light source are integrated on a circuit board.

[0010] Furthermore, this application also proposes that a light guide bracket is provided above the circuit board, and the light guide bracket has a main light-transmitting hole arranged above the first light spot matrix and a secondary light-transmitting hole arranged above the second light spot matrix; the secondary light-transmitting hole is constructed as a strip hole, with its two ends pointing to the main light-transmitting holes on both sides respectively.

[0011] Furthermore, this application also proposes that the switch unit is a push switch mounted on a circuit board, and a flexible button assembly is mounted on the main frame above the push switch. The flexible button assembly is located inside the main light-transmitting hole. The area of ​​the flexible button assembly covering the main indicator light source is constructed as a light-transmitting area, and the light of the main indicator light source can be presented outward through the flexible button assembly.

[0012] Furthermore, this application also proposes that the switching unit is a non-contact sensing unit integrated on a circuit board. The non-contact sensing unit is disposed on the circuit board inside the main light-transmitting hole and is used to identify input commands above the main light-transmitting hole.

[0013] Furthermore, this application also proposes that the non-contact sensing unit is one or more of a capacitive sensing unit, an infrared sensing unit, and an electromagnetic sensing unit.

[0014] Furthermore, this application also proposes that a light-transmitting cover be provided on the main frame above the light guide bracket, preferably made of a dark-colored material.

[0015] Furthermore, this application also proposes that the circuit board is equipped with a display module for presenting the question information, including the color of the main indicator light source and its corresponding quantity; a mode selection module, which is communicatively connected to the main control module, for switching between multiple interactive gameplay modes, including at least one of the following: a connect-the-dots mode, a number connect-the-dots mode, and a one-stroke drawing mode; in the number connect-the-dots mode, when the main control module generates a question, it first uses dark light to present multiple question paths in the first light spot matrix, and lights up at least one main indicator light source in each path as the starting end, and the main indicator light sources in the multiple question paths present different colors; in the one-stroke drawing mode, it first uses dark light to present a question path in the first light spot matrix, and lights up at least one main indicator light source in the path as the starting end; in the connect-the-dots mode, it first presets multiple question paths, and lights up at least the main indicator light sources at the beginning and end of each question path in the first light spot matrix.

[0016] As can be seen from the above, the children's educational electronic toy device and its interactive control method provided in this application solve the technical problems of discrete interactive logic and insufficient visualization of path tracking in traditional toys by the synergistic effect of the main light spot matrix and the auxiliary light spot matrix, combined with the dynamic light path feedback mechanism. It has the technical advantages of enhancing the intuitiveness of interactive logic, improving the visualization effect of path tracking, and realizing the differentiation of multi-path parallel operation.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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 mechanical connection or an electrical 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.

[0025] like Figure 1-3As shown, this embodiment relates to a children's educational electronic toy device, including a main frame 100 and a main control module disposed therein. A matrix-type interactive device is disposed on the main frame 100, which includes multiple switch units arranged in a rectangular array. Each switch unit is embedded with a main indicator light source 122, and the multiple main indicator light sources 122 form a first light spot matrix matching the switch unit array. An auxiliary indicator light source 123 is disposed in the gap area between two adjacent main indicator light sources 122, and the auxiliary indicator light sources 123 are arranged at intervals along the row and column directions of the main indicator light sources 122 to form a second light spot matrix. The main control module is electrically connected to a storage module, the switch units, the main indicator light sources 122, and the auxiliary indicator light sources 123, and is configured to control the on / off state of the corresponding main indicator light source 122 according to the trigger signal of the switch unit, to represent the activation state of the user operation node; when two adjacent main indicator light sources 122 are detected to be lit simultaneously, the auxiliary indicator light source 123 in the direction of the line connecting the two main indicator light sources 122 is activated to form a continuous light path. The main indicator light source 122 can use RGB LEDs or combinations of LEDs to display two or more light colors, thereby enhancing the visual feedback effect. The auxiliary indicator light source 123 is preferably a strip LED light or a micro LED array, the length of which is consistent with the line direction connecting adjacent main indicator light sources 122.

[0026] This technical solution transforms discrete node operations into a visual representation of a continuous path through the collaborative operation of a two-level light point matrix. Specifically, when a user triggers two adjacent switch units, the main control module not only controls the corresponding main light source to light up but also automatically activates the intermediate auxiliary light source, forming a coherent light path trajectory. Specifically, the main control module can use a preset path detection algorithm to determine the activation status of adjacent main light sources in real time and calculate the position of the auxiliary light source to be lit based on row and column coordinates. This dynamic light path generation mechanism allows the connectivity and directionality of the operation path to be intuitively presented, overcoming the technical limitation of traditional toys that can only provide feedback on discrete operations. Compared with existing technologies, this solution maintains the realism of physical interaction while achieving a visual mapping of operation logic, helping to improve children's understanding of spatial relationships and path planning.

[0027] Furthermore, the electronic toy also includes a storage module communicatively connected to the main control module. The storage module pre-stores an interactive question bank, where each question includes standard path parameters and question stem information. The main control module is further configured to: illuminate a portion of the main indicator light source 122 along the standard path on the first light spot matrix based on the question stem information from the interactive question bank; and compare the user's solution path with the question path parameters in the storage module to calculate the path matching degree. The storage module can be implemented using a flash memory chip or an SD card, and its capacity configuration must meet the data requirement of storing at least 200 questions. The standard path parameters in the interactive question bank are defined through a two-dimensional coordinate sequence, for example, using an array structure of [(x1,y1),(x2,y2)...] to record the coordinates of path nodes. The question stem information includes text descriptions or graphical prompts. Text descriptions are presented through the display module 180, and graphical prompts are conveyed through the flashing frequency or color changes of the main indicator light source 122. The path matching degree is calculated by comparing the number of differing nodes between the user's operational path coordinate sequence and the pre-stored standard path, outputting a matching degree value in percentage form. This technical solution achieves standardized question interaction in an offline environment through the synergy of hardware storage and path comparison algorithms. The pre-stored question bank provides structured question resources for path-based games, and standard path parameters serve as objective evaluation criteria, solving the problem of traditional toys relying on manual judgment. The main control module automatically generates quantitative evaluation results by comparing the user's operation trajectory with the pre-stored path in real time, avoiding errors caused by subjective judgment. Compared with existing technologies, this solution transforms discrete physical operations into quantifiable logical training, and through path visualization feedback using a light point matrix, it significantly improves the accuracy and efficiency of children's spatial cognition and logical reasoning training.

[0028] In the specific implementation, both the main indicator light source 122 and the auxiliary indicator light source 123 are constructed as RGB LED beads or combinations of LED beads capable of displaying two or more light colors. Specifically, RGB LED beads refer to light-emitting elements packaged from red, green, and blue primary color LED chips, and full-color mixing can be achieved by adjusting the current intensity of each chip. LED bead combinations refer to the integration of multiple monochromatic LEDs into the same package in a physical or optical manner, such as arranging red and blue LEDs side by side. Both implementation methods must meet the following technical requirements: the color gamut coverage must include at least the three primary colors of red, green, and blue. Therefore, this technical solution achieves the following technical effects through the dynamic control of multi-color light sources: when representing the operation state, color differences can be used to distinguish between active states (e.g., green) and error prompts (e.g., red); in path indication scenarios, different color codes can be used to distinguish multiple parallel paths (e.g., red and blue path display); in advanced gameplay, it supports logic training based on color matching (e.g., requiring children to trigger nodes in a specific color order). Compared to existing monochromatic light source solutions, this design significantly improves the information density of visual feedback, enabling the transmission of richer interactive logic within the same physical space. Simultaneously, it enhances children's cognitive efficiency in understanding operational rules through color psychology. Specifically, when applied to a number matching game mode, different colored path indicators reduce the probability of children getting confused in complex paths.

[0029] In the specific implementation scheme, the main control module, storage module, switching unit, main indicator light source 122, and auxiliary indicator light source 123 are integrated on the circuit board 140. Specifically, the main control module can be implemented using a microcontroller or embedded processor, such as an STM32 series chip, and is responsible for coordinating the operation of various functional modules. The storage module can use flash memory chips or EEPROM to store interactive question banks and user data. The main indicator light source 122 and auxiliary indicator light source 123 preferably use surface-mount LED beads, which are soldered onto the circuit board 140 using SMT technology. The main indicator light source 122 is arranged in a rectangular array, and the auxiliary indicator light source 123 fills the gaps between the main light sources in an interleaved manner. The circuit board 140 is preferably a PCB board with four or more layers, and the electrical connections between modules are achieved through inner layer traces. The main control module is connected to the storage module via an SPI bus, to the switching unit via a GPIO interface, and to the light source module via a PWM drive circuit. In this way, this integration scheme effectively reduces the number of external connection lines between modules by physically integrating all functional modules onto a single circuit board 140. The integration of the main control module and the storage module enables localized data processing and storage, reducing signal transmission delay; the coplanar arrangement of the switch unit and the light source module simplifies the correspondence between user operation and light feedback; the modules are connected by traces on the inner layer of the circuit board 140, avoiding assembly errors caused by external flying wires.

[0030] Furthermore, a light guide bracket 150 is disposed above the circuit board 140. The light guide bracket 150 has a main light-transmitting hole 151 arranged above the first light spot matrix and a secondary light-transmitting hole 152 arranged above the second light spot matrix. The secondary light-transmitting hole 152 is constructed as a strip-shaped hole, with its two ends pointing towards the main light-transmitting holes 151 on both sides. The shape of the main light-transmitting hole 151 can be designed as circular, square, or polygonal to ensure that the light from the main indicator light source 122 can be fully transmitted. The strip-shaped structure of the secondary light-transmitting hole 152 can be designed as a straight line, an arc, or a broken line. This technical solution, through the structured design of the hole positions of the light guide bracket 150, transforms the light spot matrix at the circuit board 140 level into a visualized optical path system. The main light-transmitting aperture 151 is precisely aligned with the main indicator light source 122 of the first light spot matrix, ensuring that the light from the main light source can be directly output. The strip design of the secondary light-transmitting aperture 152 matches the connection direction of the auxiliary indicator light source 123 of the second light spot matrix. When an adjacent main light source is activated, the strip aperture can completely project the light path formed by the auxiliary light source. The matrix arrangement of the main light-transmitting aperture 151 and the secondary light-transmitting aperture 152 forms a physical correspondence with the dual light spot matrix on the circuit board 140, realizing precise coupling between the light source position and the light guide path. Compared with the prior art, this solution solves the problem of insufficient path visualization accuracy in physical interactive devices through the optimized design of the light guide structure, accurately presenting the connection relationship between nodes and improving the intuitiveness and accuracy of interactive feedback.

[0031] In one embodiment, the switch unit is a push switch mounted on the circuit board 140. A resilient button assembly is mounted on the main frame 100 above the push switch and is located inside the main light-transmitting hole 151. The area of ​​the resilient button assembly covering the main indicator light source 122 is constructed as a light-transmitting area, and the light from the main indicator light source 122 can be projected outward through the resilient button assembly.

[0032] Specifically, the push-button switch can be a surface-mount micro switch or a metal spring switch, with its contacts soldered to the circuit board 140. The elastic button assembly is preferably made of silicone, with a raised structure at its bottom that contacts the push-button switch. Light transmission is achieved through localized thinning or the addition of light-transmitting material in the top light-transmitting area. The diameter of the main light-transmitting hole 151 is slightly larger than the outer diameter of the elastic button assembly, thus ensuring that the button's pressing stroke is not interfered with by the hole wall. The specific structure of the elastic button assembly can be referenced from the structure used in the patent scheme with publication number "CN220189112U". This technical solution achieves visualized operation feedback through the coupling design of mechanical structure and optical path. When the user presses the elastic button assembly, the raised bottom triggers the circuit switching of the push-button switch, and simultaneously, the light from the main indicator light source 122 shines through the light-transmitting area to display the operation status in real time. The coaxial arrangement of the light-transmitting area and the main light-transmitting hole 151 ensures that the visible angle of the light source coincides with the user's operating angle, thereby solving the problem of spatial misalignment between the operation action and the light effect feedback in traditional integrated designs. Compared with existing technologies, this design maintains the physical integration of the switching unit and the light source assembly, while simultaneously transmitting tactile feedback and visual signals through a light-transmitting button structure, thus avoiding the problem of increased device size caused by split designs.

[0033] In another implementation, the switching unit is a non-contact sensing unit integrated on a circuit board 140. The non-contact sensing unit is located on the circuit board 140 within the main light-transmitting hole 151 and is used to recognize input commands above the main light-transmitting hole 151. Specifically, the non-contact sensing unit can be implemented using one or more combinations of capacitive sensing, infrared sensing, or electromagnetic sensing technologies. Specifically, the capacitive sensing unit identifies a finger approaching or touching by detecting changes in capacitance between electrodes. This can be implemented using self-capacitance or mutual capacitance detection circuits, with self-capacitance mode suitable for single-point touch recognition and mutual capacitance mode supporting multi-point touch detection. The infrared sensing unit determines the operation position by receiving reflected infrared light signals. The electromagnetic sensing unit captures input actions based on changes in the electromagnetic field. The electromagnetic sensing unit operates based on the principle of electromagnetic resonance and requires a dedicated stylus. The stylus tip has a built-in LC resonant circuit, achieving precise positioning through electromagnetic coupling. The electromagnetic sensing unit supports high-precision pen input and can accurately capture pen strokes. As a preferred implementation, the capacitive sensing unit is configured to support multi-point touch recognition, thereby enabling accurate capture of complex gestures (such as swiping or drawing circles). Furthermore, the spatial relationship between the non-contact sensing unit and the main light-transmitting hole 151 is defined as follows: the sensing area must completely cover the projection range of the main light-transmitting hole 151, thereby ensuring that any operation by the user above the light-transmitting hole can be effectively detected. The working principle of this technical solution can be summarized as follows: Non-contact sensing technology replaces traditional mechanical buttons; the integrated design of the sensing unit and the light source on the circuit board 140 avoids mechanical wear problems caused by physical contact; the main light-transmitting hole 151 serves both as the light source transmission channel and as the positioning reference for the sensing area, enabling spatial synergy between light path visualization and command input; non-contact interaction supports new operation modes such as gesture recognition, enabling smooth input of continuous paths in games like Connect-the-Dots and One-Stroke Line Drawing. Compared with existing technologies, this solution, while retaining the light path visualization function, improves the durability of the device and expands the diversity of interaction methods, especially solving the technical defects of traditional electronic toys caused by the wear and tear of physical buttons and the single interaction mode.

[0034] Furthermore, this application proposes a technical solution of setting a light-transmitting cover 170 on the main frame 100 above the light guide bracket 150, wherein the light-transmitting cover 170 is preferably made of a dark-colored material. Specifically, the installation position of the light-transmitting cover 170 is limited to above the light guide bracket 150, and its coverage area needs to match the distribution area of ​​the main light-transmitting hole 151 and the secondary light-transmitting hole 152 on the light guide bracket 150. The material selection of the light-transmitting cover 170 includes, but is not limited to, dark gray polycarbonate, smoked acrylic, or transparent plastic with added color masterbatch, and its light transmittance is controlled within the range of 30%-80% to ensure the visibility of the main / auxiliary indicator light source while filtering ambient stray light. As a preferred embodiment, the light-transmitting cover 170 can be detachably connected to the main frame 100 through a snap-fit ​​structure for easy maintenance or replacement. Furthermore, the inner surface of the light-transmitting cover 170 can be provided with a frosted finish or a microprism structure to optimize the uniformity of light diffusion. Thus, this technical solution solves the problem of blurred light path display through the synergistic effect of physical structure and material properties. The installation of the light-transmitting cover 170 constrains the light source scattering range, preventing interference from ambient light; the dark material enhances the contrast between the main light path and the ambient background through selective light transmission. Compared with existing open light source or transparent cover designs, this solution significantly improves the recognizability of the light path trajectory without increasing circuit complexity, making it particularly suitable for interactive scenarios requiring dynamic display of continuous paths. Its innovation lies in combining optical filtering requirements with mechanical structure design, achieving both stray light suppression and effective light path focusing through the dark light-transmitting cover 170.

[0035] Furthermore, the circuit board 140 of the electronic toy is equipped with a display module 180 and a mode selection module 190. The display module 180 is used to present the question information, including the color of the main indicator light source 122 and its corresponding quantity. The display module 180 can be implemented using an LCD screen, an e-ink screen, or an LED dot matrix screen, to intuitively display the color and quantity information of the main indicator light source 122 required by the question.

[0036] The mode selection module 190 is connected to the main control module and is used to switch between various interactive gameplay modes. The mode selection module 190 can be used to switch between different interactive gameplay modes via physical buttons, touch screen or rotary switch.

[0037] The interactive gameplay modes include at least one of the following: a connect-the-dots mode, a number connect-the-dots mode, and a one-stroke drawing mode. This technical solution provides direct visual guidance through the display module 180, and the mode selection module 190 supports switching between multiple gameplay modes.

[0038] In the number matching mode, when the main control module generates a question, it first uses dim lighting in the first light spot matrix to present multiple question paths, and illuminates at least one main indicator light source 122 in each path as the starting point. The main indicator light sources 122 in the multiple question paths are displayed in different colors. Players need to press or slide according to the path, and ensure that the multiple question paths do not intersect, that is, there is no shared main indicator light source 122. Furthermore, the host's display module 180 will also display the number of main indicator light sources 122 that need to be illuminated for each question path.

[0039] In the number matching mode, color differentiation markings can be achieved using RGB LEDs, and quantity prompts can be provided through numerical display or voice broadcast. The number matching mode enhances path differentiation through color and quantity prompts.

[0040] In the one-stroke drawing mode, a problem path is first presented in the first light spot matrix using dim lighting, and at least one main indicator light source 122 in the path is illuminated as the starting point. The user is required to outline all problem paths in one stroke. The continuous presentation of paths in the one-stroke drawing mode can be achieved by using dim lighting for the main indicator light source 122. The one-stroke drawing mode trains continuous operation ability.

[0041] In the Connect-the-Dots mode, multiple problem paths are preset, and the main indicator lights 122 at both ends of each problem path are lit in the first light point matrix. Players need to press or slide to light up each problem path in sequence, ensuring that multiple problem-solving paths do not intersect, i.e., there is no shared main indicator light 122. The Connect-the-Dots mode trains children's spatial planning ability through beginning and end marking and path planning.

[0042] Compared with existing technologies, this solution combines hardware modules and program logic to transform abstract problem parameters into visual prompts of a matrix of light points. At the same time, it utilizes design elements such as color, quantity, and path isolation to achieve intuitive expression of complex gameplay rules and error prevention under limited hardware resources.
