[0001] This invention relates to the field of chessboard technology, and more specifically, to a chessboard device and control method. Background Technology

[0002] Currently, smart chessboards mainly use robotic arms to move pieces. However, robotic arms are bulky, heavy, and cannot move multiple pieces, limiting their flexibility in different situations. Furthermore, the movement of the robotic arm around the chessboard negatively impacts the user's chess-playing experience.

[0003] Therefore, how to improve the problems of using robotic arms while providing users with a good chess-playing experience has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A chessboard device, comprising:

[0008] A chessboard, on which multiple chess positions are set up, and the multiple chess positions are arranged in a first array;

[0009] The chess pieces are made of magnetic material.

[0010] An electromagnetic array is set at the bottom of the chessboard. The electromagnetic array includes multiple electromagnets with energized and de-energized states. The multiple electromagnets are arranged in a second array. The energized electromagnets can attract chess pieces, and the de-energized electromagnets can disconnect the attracted chess pieces.

[0011] The control system includes a path determination unit and a control unit. The path determination unit determines the target movement path based on the initial position and the target position of the target piece. The control unit controls the electromagnets on the target movement path to be energized to generate a first magnetic force based on the target movement path. If there is an obstructing piece on the target movement path, it controls the electromagnet corresponding to the obstructing piece to be energized to generate a second magnetic force. The second magnetic force is the same as or different from the first magnetic force, so that the target piece can move to the target position by jumping.

[0012] Optionally, in the above-mentioned chessboard device, the chessboard is provided with multiple chess squares, and the electromagnetic array includes at least electromagnets located at the four corner points of a chess square, electromagnets located between two adjacent corner points, and electromagnets located in the central area of ​​the chess square.

[0013] Optionally, in the chessboard device described above, the movement path of the target piece includes the placement of the target piece at the four corner points of each square, the midpoint between two adjacent corner points on each square, and the center of each square.

[0014] Optionally, in the chessboard device described above, when there is an obstructing piece on the target movement path of the target piece, the placement position of the target piece includes at least the midpoint between two adjacent corner points of a square where the obstructing piece is located and the center position of a square where the obstructing piece is located.

[0037] The core of this invention is to disclose a chessboard device to improve the problems existing in the use of robotic arms and provide users with a better chess playing experience.

[0038] Another object of the present invention is to provide a method for controlling a chessboard device.

[0039] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] As shown in Figure 6, an embodiment of the present invention discloses a chessboard device, including a chessboard 10, chess pieces 20, an electromagnetic array 30, and a control system.

[0041] The chessboard 10 has multiple chess positions arranged in a first array. Multiple chess pieces 20 are included, each containing a magnetic material. An electromagnetic array 30 is located at the bottom of the chessboard 10. The electromagnetic array 30 includes multiple electromagnets 31 arranged in a second array. Each electromagnet 30 has an energized state and an de-energized state. When energized, the electromagnets 30 attract the chess pieces 20; when de-energized, they disconnect from attracting the pieces. Utilizing the magnetic attraction properties of the electromagnets 31, the electromagnets 31 at the bottom of the chessboard 10 attract the chess pieces 20 containing magnetic material when energized. When an electromagnet 31 is directly below a chess piece 20, it holds the piece in place. When the electromagnet 31 is a certain distance away from the chess piece 20, the piece 20 can move towards the electromagnet 31 under its magnetic force. As shown in Figure 1, row A indicates that electromagnet 31 is not energized, and the chess piece 20 remains stationary. When electromagnet 31 is energized, under the influence of magnetic force, the chess piece 20 jumps and moves towards electromagnet 31 until it reaches above it, as shown in rows B-D. Figure 2 shows how electromagnets 31 along the target chess piece's movement path are energized sequentially to allow the target chess piece to move along the path.

[0042] The control system includes a path determination unit and a control unit. The path determination unit determines the target movement path based on the initial and target positions of the piece 20 to be moved (hereinafter referred to as the target piece). Multiple movement paths are possible, and the target movement path is the one selected from these paths. The control unit, based on the target movement path, sequentially energizes the electromagnets 31 along the target movement path to generate a first magnetic force, causing the target piece to move. If there is an obstructing piece on the target movement path, the control unit energizes the corresponding electromagnet 31 below the obstructing piece to generate a second magnetic force, attracting the obstructing piece. The second magnetic force may be the same as or different from the first magnetic force to prevent the energized electromagnets 31 along the target movement path from mistakenly attracting other pieces 20 besides the target piece, allowing the target piece to move to the target position by jumping. This jumping movement method enables the target piece to overcome obstructing pieces.

[0043] The first array is a rectangular array. The shape of the second array can be the same as or different from that of the first array, but a polygonal array is preferred for the second array. The second array can cover the first array, meaning that the second array completely overlaps with the first array, that is, an electromagnet 31 is placed under each piece position, or an electromagnet 31 is placed in other positions in addition to the electromagnets 31 under each piece position. Alternatively, the second array can cover a part of the first array, that is, at least a part of the first array has an electromagnet 31 placed under each piece position, as shown in Figure 4, or an electromagnet 31 is placed in other positions.

[0044] It should be noted that the control unit is connected to each electromagnet 31 in the electromagnetic array 30 to control the energization and de-energization of each electromagnet 31. The control unit can locate each electromagnet 31 and control each one. Specifically, the electromagnetic array 30 can be connected to the control system in an array configuration.

[0045] When there are multiple target pieces, the path determination unit determines the target movement path of each target piece based on its initial position and target position. The control unit controls each electromagnet 31 on the target movement path of each target piece to be energized in sequence so that each target piece can move simultaneously.

[0046] The magnetic material in the chess piece 20 is preferably a permanent magnet 50, which has the characteristics of small size, light weight and strong magnetism.

[0047] The chessboard device disclosed in this invention utilizes the magnetic attraction properties of electromagnet 31. When energized, the electromagnet 31 below the chessboard 10 can attract chess pieces 20 containing magnetic materials, enabling the automatic movement of the chess pieces 20. Compared to the use of a robotic arm in the prior art, the electromagnetic array 30 is arranged at the bottom of the chessboard 10, without occupying additional space beyond the chessboard 10. No additional mobile equipment is needed on the upper part of the chessboard 10, which can reduce the size of the chessboard device and reduce noise. It does not require a robotic arm to move around on the chessboard 10, and can achieve a relatively realistic game experience. It also has good teaching and remote game functions.

[0048] The chessboard device disclosed in this invention is applicable to various types of board games, such as Go and Chinese chess.

[0049] When the target piece's weight is a preset weight, the distance between the energized electromagnet 31 and the target piece is a preset distance, and the magnetic force generated by the energized electromagnet 31 is a preset magnetic force, the target piece can move by jumping. That is, by adjusting the relationship between the three, the piece 20 can be moved by jumping. As shown in Figures 1 and 2, under the action of the electromagnet 31, the target piece is lifted at a certain angle, and the target piece tilts its head at a certain angle towards the end where the electromagnet 31 is located, thus enabling it to move by jumping.

[0050] The inventors verified through simulation and experimentation that the target chess piece can jump and move. A specific experiment is selected here for illustration. The parameters of electromagnet 31 are as follows: core length 20mm, core diameter 5mm, coil current 600 ampere-turns; the parameters of chess piece 20 are as follows: weight 1.12g; center distance between electromagnet 31 and chess piece 20: horizontal 11.5mm, vertical 2mm; force on chess piece 20: horizontal net force N1 is 19.9mN, vertical net force N2 is 15.2mN, as shown in Figure 2. The resultant force of N1 and N2 is N as shown in the figure. The magnetic material in chess piece 20 is permanent magnet 50, with a diameter of 5mm and a thickness of 2mm. The material of permanent magnet 50 is neodymium iron boron N35. Under these parameters, the target chess piece exhibits a tilting tendency, as shown in rows A and B of Figure 2. The target chess piece lifts at a certain angle towards the end of the energized electromagnet 31, thus producing a jumping movement.

[0051] The chessboard 10 has multiple squares, and each square refers to one of the four corner points of a square. In some specific embodiments, as shown in Figure 6, the second array includes at least one electromagnet 31 located at the four corner points of a square (i.e., an electromagnet 31 positioned below the square), an electromagnet 31 located between two adjacent corner points, and an electromagnet 31 located in the center area of ​​the square. It should be noted that at least one electromagnet 31 is provided between two adjacent corner points, preferably one, and at least one electromagnet 31 is provided in the center area of ​​the square, preferably located in the center of the square. This arrangement reduces the possibility of an electromagnet 31 in a powered state accidentally attracting a piece 20 other than the target piece, and allows the target piece to move along the center area of ​​the square.

[0052] In one specific embodiment, an electromagnet 31 is set between two adjacent corner points and located at the midpoint between the two adjacent corner points. An electromagnet 31 is set in the center area of ​​the chessboard and located at the center of the chessboard. This arrangement allows the target piece to have multiple movement paths. In addition to moving along the horizontal and vertical lines forming the chessboard, it can also move along the center line of the chessboard. If there is an obstructing piece on the movement path, the target piece can move along the center line of the chessboard. By adjusting the magnetic force of the energized electromagnet 31, the target piece can move along the center line of the chessboard, thereby gradually jumping over the obstructing piece.

[0053] Based on the above embodiments, in the movement path of the target piece, the placement position of the target piece includes the four corner positions of each square, the midpoint position between two adjacent corner positions on each square, and the center position of each square.

[0054] When there is an obstructing piece on the target piece's movement path, the target piece's placement position must include at least the midpoint between the two adjacent corner points of the square containing the obstructing piece and the center of the square containing the obstructing piece. This allows the target piece to move to the center of one of the squares covered by the obstructing piece, thus partially landing on the obstructing piece by jumping over it. This arrangement minimizes the possibility of the target piece overturning when crossing an obstructing piece.

[0055] As shown in Figure 6, this figure represents a portion of the chessboard 10. Within this area, the first array is a 6×6 square array, and the second array is an 11×11 square array, overlapping the first array. The second array includes electromagnets 31 located below each chess piece, an electromagnet 31 located at the midpoint between the two corner points of the square, and an electromagnet 31 located at the center of the square. The white piece shown in the figure is the target piece. One of the two white pieces' positions is the initial position, and the other is the target position. For ease of explanation, the position of the white piece located at the top in the figure is taken as the initial position, and the position of the white piece located at the bottom is taken as the target position.

[0056] The dotted line in the diagram represents the target piece's movement path. As can be seen, there are blocking pieces on both sides of the target movement path, in two groups of two. By sequentially energizing the electromagnets 31 along the target movement path, the target piece moves half a square at a time. After two moves, the target piece is in the center of the square, with part of it resting on the first group of blocking pieces. After three moves, the target piece's center is at the midpoint of the line connecting the centers of the first group of blocking pieces, meaning the target piece jumps onto both blocking pieces. The target piece continues moving until the fifth move, at which point it crosses the first group of blocking pieces and continues its jump-like movement along the target movement path. Crossing the second group of blocking pieces is similar to crossing the first group and will not be described further here.

[0057] In some specific embodiments, the second array covers the first array. Here, "covering" means that the second array overlaps with the first array or the coverage area of ​​the second array is larger than that of the first array. That is, at least the four corner points of all the chess squares (each chess position) are provided with electromagnets 31, or electromagnets 31 are provided at the four corner points of the chess squares (each chess position), between two adjacent corner points, and in the central area of ​​the chess square. This method can ensure the movement speed of the chess pieces 20 and the simultaneous movement of multiple chess pieces 20.

[0058] In some other specific embodiments, the second array covers a portion of the first array, as shown in Figure 3. Here, the electromagnetic array 30 can be a 1×1 array, i.e., containing only one electromagnet 31; or the electromagnetic array 30 covers only a portion of the chess positions, as shown in Figures 4 and 5; or the electromagnetic array 30 includes electromagnets 31 positioned at the four corner points of a portion of the chess square, between adjacent corner points, and in the center area of ​​the corresponding chess square, as shown in Figure 6. The chessboard device includes a drive mechanism 40, which is connected to the electromagnetic array 30 to drive the electromagnetic array 30 to move along a first direction and a second direction, the first direction and the second direction referring to the horizontal and vertical directions of the chessboard 10, respectively. The drive mechanism 40 is electrically connected to the control system.

[0059] As shown in Figure 3, when the electromagnetic array 30 contains only one electromagnet 31, the driving mechanism 40 may include a drive motor. The drive motor is connected to the electromagnet 31, and the electromagnet 31 is placed below the target piece. The drive motor drives the electromagnet 31 to move along the target movement path to the target position. It should be noted that in this embodiment, multiple electromagnets 31 can be provided, each with its own drive mechanism 40. When there are multiple target pieces, multiple target pieces can move simultaneously. This method is only applicable when there are no obstructing pieces on the target movement path.

[0060] In the embodiments shown in Figures 4-6, the path determination unit determines the target movement path and then determines whether the initial position and target position of the target piece are within the coverage area of ​​the electromagnetic array 30. When the target piece is within the coverage area of ​​the electromagnetic array 30, the control unit controls each electromagnet 31 on the target movement path to be energized sequentially, so that the target piece moves from the initial position to the target position. When the target piece is not within the coverage area of ​​the electromagnetic array 30, the drive mechanism 40 drives the electromagnetic array 30 to move, so as to at least cover the initial position of the target piece. Then, the control unit controls each electromagnet 31 on the target movement path to be energized sequentially. When the target position of the target piece is not within the coverage area of ​​the electromagnetic array 30, the drive mechanism 40 can be used multiple times to drive the electromagnetic array 30 to move the target piece from the initial position to the target position. This method reduces costs compared to the method of the second array covering the first array.

[0061] In the embodiment shown in Figure 6, the movement path of the target piece is more than that of the arrangement of electromagnets 31 shown in Figures 4-5. When there are blocking pieces on the movement path, this method allows the target piece to jump over the blocking pieces to reach the target position.

[0062] In some specific embodiments, the drive mechanism 40 includes a drive motor and a lead screw mechanism. The drive motor is driven and connected to the lead screw mechanism. The electromagnetic array 30 is threadedly connected to the lead screw mechanism and slidably engaged with the chessboard 10. The drive motor is connected to the control system. The drive motor drives the lead screw in the lead screw mechanism to rotate, thereby moving the electromagnetic array 30. In this embodiment, the electromagnetic array 30 can cover all rows or all columns of the chessboard 10. Only one drive motor and lead screw mechanism are provided, and the electromagnetic array 30 is driven to move through the drive motor and lead screw mechanism. This method is preferred.

[0063] When the electromagnetic array 30 only covers a portion of the chessboard 10, and not all rows and columns, at least two drive motors are included. A lead screw mechanism corresponds one-to-one with each drive motor. One lead screw mechanism drives the electromagnetic array 30 to move along a first direction, and the other drives it along a second direction. At least one drive mechanism 40 engages with the chessboard 10 in a sliding manner. The drive motors are electrically connected to the control system. The control system first determines whether the target piece is within the coverage area of ​​the electromagnetic array 30. If not, the control system activates the drive mechanism 40 to move the electromagnetic array 30 to cover the chessboard area where the target piece is located. Subsequently, the control unit sequentially energizes each electromagnet 31 along the target piece's movement path, causing the target piece to move from its initial position to its target position in a jumping motion.

[0064] In some other embodiments, the drive mechanism 40 includes a drive cylinder, which is connected to the electromagnetic array 30 via a transmission connection. The electromagnetic array 30 is slidably coupled to the chessboard 10, and the drive cylinder is also connected to the control system. When the electromagnetic array 30 covers all rows or all columns of the chessboard, only one drive cylinder may be required to drive the electromagnetic array 30 to move.

[0065] When the electromagnetic array 30 covers only a portion of the chessboard 10, the driving cylinders may include multiple cylinders arranged along the rows and columns of the electromagnetic array 30. Each driving cylinder is equipped with a connector connected to the electromagnetic array 30. Based on the movement path of the electromagnetic array 30, the corresponding driving cylinder is activated to move the electromagnetic array 30. In other specific embodiments, the driving cylinders include a first driving cylinder that drives the electromagnetic array 30 to move along a first direction and a second driving cylinder that drives the electromagnetic array 30 to move along a second direction. Both the first and second driving cylinders are slidably engaged with the chessboard 10. Based on the movement direction of the electromagnetic array 30, the first driving cylinder can slide along the chessboard 10, and then the first driving mechanism connects to the electromagnetic array 30 to move the electromagnetic array 30 along the first direction. Subsequently, the second driving cylinder slides along the chessboard 10, and then the second driving mechanism connects to the electromagnetic array 30 to move the electromagnetic array 30 along the second direction.

[0066] Of course, the drive mechanism 40 can also employ a combination of a drive motor and a rack and pinion mechanism. The electromagnetic array 30 has a rack, and the drive motor has a gear. The gear meshes with the rack, enabling the electromagnetic array 30 to move along the first and second directions. Alternatively, the drive mechanism 40 can use other methods, as long as they enable the movement of the electromagnetic array 30.

[0067] In some specific embodiments, the chess-playing operation also includes the entry and exit of chess pieces 20. In order to place the chess pieces 20 that are entered and exited, the chessboard 10 includes a playing area and a chess piece storage area. The playing area is used for chess players to play chess, and the chess piece storage area is used to store the chess pieces 20 that are entered or exited. Specifically, the chess piece storage area can be set around the playing area or on both sides of the playing area.

[0068] Furthermore, the present invention also discloses a method for controlling a chessboard device, which controls the aforementioned chessboard device, specifically including the following steps:

[0069] Step S1: Obtain the initial position, target position, and target piece;

[0070] First, determine the target piece, which is piece 20 to be moved, and determine the initial position and target position of the target piece.

[0071] Step S2: Determine the target's movement path based on the initial position and the target position;

[0072] The control unit determines the movement path of the target piece based on its initial position and target position. There are usually multiple movement paths, and one of them is selected as the target movement path.

[0073] Step S3: Determine if there are any obstructing pieces on the target movement path. If so, energize each electromagnet 31 on the target movement path sequentially to generate a first magnetic force, and energize the electromagnet 31 corresponding to the obstructing piece to generate a second magnetic force. The second magnetic force is different from the first magnetic force, so that the target piece moves to the target position by jumping. If there are no obstructing pieces on the target movement path, energize each electromagnet 31 on the target movement path sequentially to generate a first magnetic force, so that the target piece moves to the target position by jumping.

[0074] The chessboard device control method disclosed in this invention determines the target movement path based on the initial position and the target position as follows: when there are multiple movement paths, the shortest path is the target movement path; or, when there are multiple movement paths, one path can be designated as the target movement path, preferably the shortest path.

[0075] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
