Description

Technical Field

[0001] This utility model relates to the field of competitive board games, and in particular to a movable chess piece and a chessboard. Background Technology

[0002] Chess, an internationally recognized board game, is an ancient two-player intellectual game and a competitive sport. Chess is a very interesting and beneficial activity that can improve players' attention and thinking abilities. It was once included as an official event in the Olympic Games.

[0003] Patent document CN213375076U discloses a portable chess piece and chessboard, including a chessboard body composed of multiple squares. Each square has a groove at its top, and a chess piece is placed on top of each groove. Each chess piece has a feature graphic on its top, and a base is fixedly connected to the bottom of the feature graphic. A fixing ring is fixedly connected to the bottom of the base, and the fixing ring is movably engaged with the groove. Both the top and bottom of the chessboard body have caps. This invention improves the neatness and aesthetics of the chess pieces by using a movably engaged fixing ring with the groove. The groove and fixing ring have elliptical cross-sectional shapes. The chessboard body is made of silicone material, allowing it to be rolled into a cylinder for easy carrying and storage of the chess pieces. This device is simple in structure, easy to use, small in size, and portable. The facing chess pieces facilitate gameplay.

[0004] However, most smart chessboards on the market that can move pieces currently use robotic arm solutions or XYZ three-axis moving platform solutions to magnetically move pieces one by one. This method cannot move multiple pieces at the same time, and the pieces cannot be individually identified as each type. It is also costly, consumes a lot of power, and generates a lot of noise from the mechanical parts. Utility Model Content

[0005] (a) Technical problems to be solved The purpose of this invention is to provide a movable chess piece and a chessboard to solve the problems mentioned in the background art, such as the inability to move multiple pieces simultaneously, the inability to individually identify each type of piece, high cost, high power consumption, and high noise from the mechanical parts.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a movable chess piece and a chessboard, comprising a chess piece body and a chessboard base. A support base is fixedly connected to the bottom of the chess piece body. A motor base is fixedly connected inside the support base. Two sets of rotating components are rotatably connected inside the motor base. Two sets of positioning boxes are engaged on both sides of the chessboard base. Limiting components are slidably connected inside the positioning boxes. Each rotating component includes a rotating shaft rotatably connected inside the motor base. A gear set is sleeved on the surface of the rotating shaft. A drive motor is fixedly connected to one side of the gear set. The limiting component includes a sliding plate slidably connected inside the positioning box. A support spring is fixedly connected to one end of the sliding plate. A positioning rod is sleeved inside the support spring.

[0007] As a further embodiment of this utility model, a PCB control board is provided at the bottom of the chess piece body, a wheel is sleeved at one end of the rotating shaft, and an opening groove adapted to the wheel is provided at the bottom of the support base.

[0008] As a further embodiment of this utility model, the inside of the slide plate is provided with a sliding groove, and a retaining ring is fixedly connected to the inner wall of the sliding groove.

[0009] As a further embodiment of this utility model, a limiting rod is engaged with the surface of the retaining ring, and a wooden cover plate is fixedly connected to the top of the limiting rod.

[0010] As a further embodiment of this utility model, the interior of the wooden cover is provided with several sets of LED lights, and a PET film is fixedly connected to the top surface of the wooden cover.

[0011] As a further embodiment of this utility model, an identification circuit board is provided at the bottom of the wooden cover plate, and an identification control circuit board is provided at the bottom of one side of the identification circuit board.

[0012] As a further embodiment of this utility model, a main control circuit board is provided on one side of the inner bottom wall of the chessboard base, and a microphone is provided on the top surface of the main control circuit board.

[0013] As a further embodiment of this utility model, a main control MCU is provided on the top surface of the main control circuit board, and a microphone circuit board is provided on the surface of the main control circuit board.

[0014] As a further embodiment of this utility model, a battery cover is provided at the bottom of one side of the chessboard base, and a rechargeable battery is provided at the top of the battery cover.

[0015] As a further embodiment of this utility model, connecting plates are fixedly connected to both sides of the positioning box, and threaded holes are opened on the surfaces of the connecting plates and the chessboard base, with bolts passing through the inside of the threaded holes.

[0016] (III) Beneficial Effects This utility model provides a movable chess piece and a chessboard, which has the following beneficial effects: 1. This mobile chess piece and chessboard, through the setting of the rotating component, has an independent movable car at the bottom of each piece. The car consists of two drive motors, gear sets, and wheels. The wheels are independently controlled by the two drive motors, enabling forward, backward, left, and right turning movements. Each car has a 2.4G radio frequency chip for communication with the main control board below. The radio frequency chip transmits and receives data at a speed of 0.5ms, enabling high-speed dual-channel communication between 34 or more cars and the host, thereby scanning the car's position at high speed and achieving real-time control. Each car's positioning uses two wound inductors on each side. The main control MCU emits PWM frequency to the inductors. The bottom of the product has an XY multi-channel antenna group. By time-division multiplexing the electromagnetic induction generated by the inductors, the position of the car is calculated. After the main control scans the accurate position of each car in real time, it controls the movement of the cars through 2.4G communication to achieve the overall movement function. The main control simultaneously launches the chessboard APP application, allowing customers to realize AI chess games, online chess games, automatic chess game setup, and other functions.

[0017] 2. This movable chess piece and chessboard, through the setting of the limiting component, when it is necessary to open the chessboard for internal inspection, pressing the sliding plate causes the support spring to contract under force, the sliding plate slides in the positioning box, and then the limiting rod slides inside the sliding plate's groove. The retaining ring disengages from the surface of the limiting rod, thereby pulling the wooden cover plate, allowing the limiting rod to be pulled out from the top of the positioning box. This achieves the effect of convenient disassembly and assembly of the chessboard, facilitating the internal inspection of the chessboard and avoiding cumbersome disassembly and assembly, thus avoiding increased time costs for inspection.
