Description

Technical Field

[0001] This utility model relates to an intelligent chessboard. Background Technology

[0002] Existing electronic chessboards on the market typically separate the pieces from the board, which is insufficient for portable piece storage. They also lack in terms of intelligence, particularly in piece position recognition, player interaction, and real-time feedback. Most electronic chessboards require players to press membrane switches built into the board squares to recognize piece movements, failing to automatically identify movement and resulting in a poor playing experience, especially for beginners. To address these pain points, we propose a novel intelligent chessboard design. Utility Model Content

[0025] This invention provides an intelligent chessboard.

[0026] like Figure 1-3As shown, the chessboard provided in this embodiment of the present invention includes a base shell 10 and a chessboard component 20 detachably mounted on the base shell 10. The base shell has a chess piece storage compartment 30, which contains EVA foam 32. The EVA foam has placement holes 31 for storing chess pieces, and the chess piece storage compartment has a chess piece door 33 to protect and prevent the EVA foam and chess pieces from falling out. Therefore, in this technical solution, chess pieces can be stored in the placement holes 31 within the chess piece storage compartment 30, achieving portable storage and retrieval, thus improving ease of use.

[0027] Specifically, the chess piece storage compartment 30 is equipped with EVA foam 32, and the placement holes 31 are opened on the foam 32 according to the shape of each chess piece, which facilitates the neat storage of the chess pieces, and at the same time, the foam 32 can also effectively protect the chess pieces.

[0028] In the above embodiment, the chessboard further includes a control component 40 mounted on the bottom shell 10, and the control component 40 is connected to the chessboard component 20.

[0029] The chessboard component 20 includes a faceplate 21 and a chessboard panel 22 disposed on the faceplate 21. A Hall effect sensor plate 23 is disposed on the side of the faceplate 21 opposite to the chessboard panel 22. A Hall effect switch sensor is disposed in each chessboard square 221 of the chessboard panel 22 by the Hall effect sensor plate 23. A magnetic element is disposed on the bottom of each chess piece. The Hall effect sensor plate 23 is electrically connected to the control component 40. In this embodiment, since a Hall effect switch sensor is placed on the Hall effect sensor plate 23 corresponding to each chessboard square 221, when a chess piece with a magnetic element on its bottom is placed on the chessboard or moved by being captured, the Hall effect switch sensor can accurately sense the change in magnetic field. After the change in magnetic field, the output level of the Hall effect switch sensor changes accordingly. The central processing unit on the main control board 42 uses 16 I / O ports in an 8x8 configuration to scan the output levels of all 64 Hall effect sensors on the Hall sensor board 23 at high speed. By judging the changes in the output levels of the 64 Hall effect sensors, and in conjunction with the chess engine algorithm built into the central processing unit, it determines whether the current piece has a valid move and whether the current move violates the rules of chess, thereby completing the task of identifying the position and action of the piece.

[0030] Meanwhile, an LED light 24 is provided at the Hall switch, and the LED light 24 is electrically connected to the control component 40. The LED light 24 is a red-green dual-color LED light. Optionally, green can represent the square belonging to white and indicate the move for white, while yellow, obtained by mixing red and green light simultaneously, can represent the square belonging to black and indicate the move for black. Red is used to indicate incorrect placement of pieces.

[0031] The light emitted by the LED light 24 is projected through 64 round holes on the faceplate 21 onto the light-transmitting holes 222 on the chessboard panel, and is presented to the user in a visual manner. The light-transmitting holes 222 are located at the lower right corner of the chessboard grid 221 and coincide with the position of the LED light 24.

[0032] This application uses LEDs 24 of different colors to indicate the black and white sides respectively, making the game clearer and easier to understand. At the same time, the application of Hall switches improves the accuracy of piece position recognition, and makes the user's operation of capturing and placing pieces as natural as playing chess on a traditional chessboard such as paper or wood, reducing the possibility of misoperation.

[0033] In this invention, a magnetic element is installed on the bottom of the chess piece. When the user lifts or places the piece, they will feel a magnetic attraction. Simultaneously, the Hall effect sensor on the Hall effect sensor motherboard of the chessboard component 20 can sense the lifting and placing of the piece on the board. After this action signal is detected by the central processing unit of the main control board, the main control board 42 outputs a control signal to trigger the corresponding LED lights 24, emitting different colors to indicate the position information of the black and white pieces, and displaying the movement coordinates on the screen. Therefore, in this invention, the Hall effect sensor enables the user to naturally capture and place pieces, the LED lights 24 provide light prompts for the movement, and the display screen outputs coordinates and menu information to the user, providing a good human-computer interface for users to understand and master the rules and moves of chess, reducing the difficulty for beginners to learn chess.

[0034] In the above embodiment, the control component 40 includes a control board cover 41 and a main control board 42. The control board cover 41 covers the bottom shell 10 to form a receiving cavity, and the main control board 42 is disposed in the receiving cavity and electrically connected to the chessboard component 20. The control component 40 includes a display screen 43 mounted on the control board cover 41, and the display screen 43 is electrically connected to the main control board 42. The control component 40 also includes a plurality of control buttons 44, and the plurality of control buttons 44 are electrically connected to the main control board 42.

[0035] The display screen 43 is used to display the coordinates of the moves made by the user and the computer (such as E2, E4), move hints, current position score, game result and other information, providing intuitive human-computer interaction feedback.

[0036] The main control board 42 is responsible for processing data from the Hall switches, operating the function keys, controlling the updates of the LCD display 43, and managing the LED indicator system. The central processing unit of the main control board 42 uses a high-performance 32-bit microcontroller with an operating speed of 240MHz, and is equipped with sufficient FLASH (2MB), PSRAM (8MB), and SRAM (288KB) to support complex game analysis and data processing.

[0037] The Hall switch array is connected to the central processing unit via a high-speed I / O interface to ensure real-time data transmission. Magnetic components are placed on the bottom of the chess pieces to ensure accurate sensing of the pieces within the squares.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
