[0037] The core of the present invention is to disclose a chessboard device to improve the problems existing in the method of using a mechanical arm and provide users with a good chess playing experience.

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

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] like Figure 6 As shown, 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] Among them, a plurality of chess positions are arranged on the chessboard 10, and the plurality of chess positions are arranged in a first array form. The chess pieces 20 include a plurality of pieces, and each piece 20 is provided with a magnetic material electromagnetic array 30 arranged at the bottom of the chessboard 10. The electromagnetic array 30 includes a plurality of electromagnets 31, and the plurality of electromagnets 31 are arranged in a second array form. The electromagnets 30 include a power-on state and a power-off state. The electromagnets 30 in the power-on state can adsorb the chess pieces 20, and the electromagnets 31 in the power-off state can stop adsorbing the chess pieces, that is, by utilizing the magnetic attraction characteristics of the electromagnets 31, the electromagnets 31 at the bottom of the chessboard 10 can attract the chess pieces 20 containing magnetic materials when powered on. When the electromagnets 31 are located directly below the chess pieces 20, they can adsorb the chess pieces 20. When the electromagnets 31 are separated from the chess pieces 20 by a certain distance, the chess pieces 20 can move toward the direction of the electromagnets 31 under the magnetic force of the electromagnets 31. Figure 1 As shown, row A in the figure shows that the electromagnet 31 is in an unpowered state, at which time the chess piece 20 is fixed. When the electromagnet 31 is powered, under the action of the magnetic force, the chess piece 20 jumps and moves toward the electromagnet 31 until it moves above the electromagnet 31, as shown in rows B-D in the figure. Figure 2 As shown, the electromagnets 31 on the moving path of the target chess piece are energized in sequence so that the target chess piece can move along the moving path.

[0042] The control system includes a path determination unit and a control unit. The path determination unit determines the target moving path according to the initial position and target position of the chess piece 20 (hereinafter referred to as the target chess piece) to be moved. Here, the moving paths include multiple paths, and the target moving path refers to one of the multiple moving paths. The control unit controls the electromagnets 31 on the target moving path to be energized in sequence according to the target moving path to generate a first magnetic force to move the target chess piece. If there is a blocking chess piece on the target moving path, the control unit controls the corresponding electromagnet 31 under the blocking chess piece to be energized to generate a second magnetic force to adsorb the blocking chess piece. The second magnetic force is the same as or different from the first magnetic force to prevent the electromagnet 31 on the target moving path from erroneously attracting other chess pieces 20 except the target chess piece when it is energized, so that the target chess piece moves to the target position in a jumping manner. The jumping manner enables the target chess piece to cross the blocking chess piece.

[0043] The first array is a rectangular array, and the shape of the second array can be the same as or different from that of the first array. The second array is preferably a polygonal array. The second array can cover the first array, and covering here means that the second array completely overlaps with the first array, that is, an electromagnet 31 is set under each chess position, or in addition to the electromagnet 31 under each chess position, other positions are also set with electromagnets 31. Or 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 under each chess position, such as Figure 4 As shown in FIG. , or an electromagnet 31 is further provided at 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 power on and off of each electromagnet 31. The control unit can locate each electromagnet 31 and realize the control of each electromagnet 31. Specifically, the electromagnetic array 30 can be connected to the control system in an array connection manner.

[0045] When there are multiple target chess pieces, the path determination unit determines the target moving paths of the respective target chess pieces according to their initial positions and target positions, and the control unit controls the electromagnets 31 on the target moving paths of the respective target chess pieces to be energized in sequence so that the respective target chess pieces 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 the embodiment of the present invention utilizes the magnetic attraction characteristics of the electromagnet 31. The electromagnet 31 below the chessboard 10 can attract the chess piece 20 containing magnetic material when powered on, and can realize the automatic movement of the chess piece 20. Compared with the method of using a robotic arm in the prior art, the electromagnetic array 30 is arranged at the bottom of the chessboard 10, and does not occupy any additional space beyond the chessboard 10. There is no need to add additional mobile equipment on the upper part of the chessboard 10, which can reduce the size of the chessboard device and has low noise. There is no need for a robotic arm to go around the chessboard 10, so a relatively realistic chess game experience can be achieved, and it also has good teaching and remote chess game functions.

[0048] The chessboard device disclosed in the embodiment of the present invention is applicable to various types of chess and cards, such as Go, chess, etc.

[0049] When the weight of the target chess piece is the preset weight, the distance between the energized electromagnet 31 and the target chess piece is the preset distance, and the magnetic force generated by the energized electromagnet 31 is the preset magnetic force, the target chess piece can move in a jumping manner, that is, by adjusting the relationship between the three, the chess piece 20 can move in a jumping manner. Figure 1 and Figure 2 As shown in , the target chess piece is lifted up at a certain angle under the action of the electromagnet 31, and the target chess piece tilts at a certain angle toward one end where the electromagnet 31 is located, so that it can move in a jumping manner.

[0050] The inventor verified through simulation and experiment that the target chess piece can jump and move. A specific experiment is selected here for illustration. The parameters of the electromagnet 31 are as follows: core length 20mm, core diameter 5mm, coil current 600 ampere-turns; the parameters of the chess piece 20 are as follows: weight of the chess piece 20 1.12g; center distance between the electromagnet 31 and the chess piece 20: horizontal direction 11.5mm, vertical direction 2mm, force magnitude of the chess piece 20: horizontal direction resultant force N1 is 19.9mN, vertical direction resultant force N2 is 15.2mN, as shown in FIG. Figure 2 As shown in the figure, the combined force of N1 and N2 is N as shown in the figure. The magnetic material in the chess piece 20 is a permanent magnet 50. The diameter of the permanent magnet 50 is 5 mm, the thickness is 2 mm, and the material of the permanent magnet 50 is NdFeB N35. Under this parameter, the target chess piece shows a tendency to tilt, that is, Figure 2 As shown in rows A and B, the target chess piece is lifted up at a certain angle toward one end of the energized electromagnet 31, thereby generating a jumping movement.

[0051] A plurality of chess grids are arranged on the chessboard 10. The chess positions refer to the four corner points of the chess grids. In some specific embodiments, for example, Figure 6As shown, the second array at least includes electromagnets 31 located at four corner points of a chess grid (i.e., electromagnets 31 disposed below chess positions), electromagnets 31 located between two adjacent corner points, and electromagnets 31 located in the center area of ​​the chess grid. It should be noted that at least one electromagnet 31 is included between two adjacent corner points, preferably one is provided, and at least one electromagnet 31 is included in the center area of ​​the chess grid, preferably located in the center position of the chess grid. This arrangement can reduce the possibility that the electromagnet 31 in the energized state on the moving path mistakenly attracts chess pieces 20 other than the target chess piece, and can make the target chess piece move along the center area of ​​the chess grid.

[0052] In a specific embodiment, one electromagnet 31 is provided between two adjacent corner points and is located at the midpoint of the two adjacent corner points. One electromagnet 31 is provided in the central area of ​​the chessboard and is located at the center of the chessboard. This arrangement enables the target chess piece to have multiple moving paths. In addition to being able to move along the horizontal and straight lines forming the chessboard, it can also move along the center line of the chessboard. If there are blocking chess pieces on the moving path, the target chess piece can be moved along the center line of the chessboard. By adjusting the magnetic force of the energized electromagnet 31, the target chess piece can move along the center line of the chessboard, thereby gradually jumping over the blocking chess piece.

[0053] Based on the above embodiment, in the moving path of the target chess piece, the landing position of the target chess piece includes the four corner positions of each chess square, the midpoint position between two adjacent corner positions on each chess square, and the center position of each chess square.

[0054] When there is a blocking chess piece on the target moving path of the target chess piece, the target chess piece's landing position at least includes the midpoint position between two adjacent corner points of a chess square where the blocking chess piece is located and the center position of a chess square where the blocking chess piece is located, so that the target chess piece can move to the center position of a chess square covered by the blocking chess piece, thereby partially pressing on the blocking chess piece in a jumping movement manner to cross over the blocking chess piece. This setting method can ensure that the target chess piece is less likely to overturn when crossing over the blocking chess piece.

[0055] like Figure 6As shown in the figure, a partial area of ​​the chessboard 10 is shown, in which the first array is a 6×6 square array and the second array is an 11×11 square array. In this area, the second array covers the first array. The second array includes an electromagnet 31 located below each chess position, an electromagnet 31 located at the midpoint between the two corner points of the chess grid, and an electromagnet 31 located at the center of the chess grid. The white chess piece shown in the figure is the target chess piece, and one of the two positions of the white chess pieces is the initial position and the other is the target position. For the convenience of explanation, the position of the white chess piece located at the upper position in the figure is the initial position, and the position of the white chess piece located at the lower position is the target position.

[0056] The path indicated by the dotted line in the figure is the target moving path of the target chess piece. It can be seen from the figure that there are blocking chess pieces on both sides of the target moving path, and the blocking chess pieces include two groups, two in each group. By controlling the electromagnets 31 on the target moving path to be energized in sequence, the target chess piece moves half a chess grid each time. When the target chess piece moves twice, the target chess piece is located at the center of the chess grid, and a part of the target chess piece is pressed on the first group of blocking chess pieces; when the target chess piece moves three times, the center of the target chess piece is located at the midpoint of the line connecting the centers of the first group of blocking chess pieces, that is, at this time, the target chess piece jumps to the two blocking chess pieces; then the target chess piece continues to move until the fifth time, the target chess piece crosses the first group of blocking chess pieces, and then continues to move in a jumping manner along the target moving path. The target chess piece crossing the second group of blocking chess pieces is similar to crossing the first group of blocking chess pieces, which will not be repeated here.

[0057] In some specific embodiments, the second array covers the first array, where covering means that the second array overlaps with the first array or the coverage area of ​​the second array is larger than the coverage area of ​​the first array, that is, at least the four corner positions (each chess position) of all chess grids are provided with electromagnets 31, or the four corner positions (each chess position) of the chess grid, between two adjacent corner positions, and the central area of ​​the chess grid are provided with electromagnets 31. This method can ensure the movement speed of the chess piece 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, such as Figure 3 As shown, the electromagnetic array 30 here can be a 1×1 array, that is, it only includes one electromagnet 31; or the electromagnetic array 30 only covers each chess position in a partial area, such as Figure 4 and Figure 5 or the electromagnetic array 30 includes an electromagnet 31 disposed at four corner positions of a part of the chess grid, between two adjacent corner positions and in the central area of ​​the corresponding chess grid, such as Figure 6The chessboard device includes a driving mechanism 40, which is in transmission connection with the electromagnetic array 30 to drive the electromagnetic array 30 to move in a first direction and a second direction, wherein the first direction and the second direction refer to the horizontal direction and the vertical direction of the chessboard 10 respectively, and the driving mechanism 40 is electrically connected to the control system.

[0059] like Figure 3 As shown, when the electromagnetic array 30 includes only one electromagnet 31, the drive mechanism 40 may include a drive motor, which is transmission-connected to the electromagnet 31, and the electromagnet 31 is placed below the target chess piece. The drive motor drives the electromagnet 31 to move to the target position along the target moving path. It should be noted that in this embodiment, multiple electromagnets 31 can be provided, and each electromagnet 31 has its own drive mechanism 40. When there are multiple target chess pieces, multiple target chess pieces can be moved simultaneously. This method is only applicable to the case where there is no blocking chess piece on the target moving path.

[0060] like Figure 4-Figure 6 In the illustrated embodiment, the path determination unit determines the target moving path, and then determines whether the initial position and target position of the target chess piece are within the coverage range of the electromagnetic array 30. When the target chess piece is within the coverage range of the electromagnetic array 30, the control unit controls each electromagnet 31 on the target moving path to be energized in sequence, so that the target chess piece moves from the initial position to the target position. When the target chess piece is not within the coverage range of the electromagnetic array 30, the electromagnetic array 30 is driven to move by the driving mechanism 40 to at least cover the initial position of the target chess piece, and then the control unit controls each electromagnet 31 on the target chess piece moving path to be energized in sequence. When the target position of the target chess piece is not within the coverage range of the electromagnetic array 30, the electromagnetic array 30 can be driven to move by the driving mechanism 40 multiple times, so that the target chess piece moves from the initial position to the target position. Compared with the method in which the second array covers the first array, this method can reduce costs.

[0061] Figure 6 In the embodiment shown, the moving path of the target chess piece is more than Figure 4-Figure 5 The arrangement of the electromagnets 31 shown in the figure enables the target chess piece to jump over the blocking chess piece to reach the target position when there is a blocking chess piece on the moving path.

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

[0063] When the electromagnetic array 30 only covers a part of the chessboard 10, and does not cover all the rows and columns of the chessboard 10, the driving motors include at least two, and the lead screw mechanisms correspond to the driving motors one by one, wherein one lead screw mechanism is used to drive the electromagnetic array 30 to move in the first direction, and the other lead screw mechanism is used to drive the electromagnetic array 30 to move in the second direction, wherein at least one driving mechanism 40 is in a sliding cooperation with the chessboard 10. The driving motor is electrically connected to the control system, and the control system first determines whether the target chess piece is within the coverage range of the electromagnetic array 30. If not, the control system controls the driving mechanism 40 to start, so as to move the electromagnetic array 30 to the chessboard range where the target chess piece is located, and then the control unit controls each electromagnet 31 on the moving path of the target chess piece to be energized in sequence, so that the target chess piece moves from the initial position to the target position in a jumping manner.

[0064] In other specific embodiments, the driving mechanism 40 includes a driving cylinder, which is in driving connection with the electromagnetic array 30, and the electromagnetic array 30 is slidably matched with the chessboard 10, and the driving cylinder is connected to the control system. When the electromagnetic array 30 covers all rows or all columns of the chessboard, only one driving cylinder can be provided, and the electromagnetic array 30 is driven to move by the driving cylinder.

[0065] When the electromagnetic array 30 only covers a partial area of ​​the chessboard 10, the driving cylinder may include a plurality of cylinders arranged along the rows and columns of the electromagnetic array 30, each of which is provided with a connector connected to the electromagnetic array 30, and the corresponding driving cylinder is activated according to the moving path of the electromagnetic array 30 to drive the electromagnetic array 30 to move. In other specific embodiments, the driving cylinder includes a first driving cylinder that drives the electromagnetic array 30 to move in a first direction and a second driving cylinder that drives the electromagnetic array 30 to move in a second direction, and the first driving cylinder and the second driving cylinder are both slidably matched with the chessboard 10, and the first driving cylinder can slide along the chessboard 10 according to the moving direction of the electromagnetic array 30, and then the first driving mechanism is connected to the electromagnetic array 30 to move the electromagnetic array 30 in the first direction, and then the second driving cylinder slides along the chessboard 10, and then the second driving mechanism is connected to the electromagnetic array 30 to move the electromagnetic array 30 in the second direction.

[0066] Of course, the driving mechanism 40 can also adopt a mode of matching a driving motor and a gear rack, a rack is provided on the electromagnetic array 30, and a gear is provided on the driving motor, and the gear and the rack are meshed so that the electromagnetic array 30 can move in the first direction and the second direction. Of course, the driving mechanism 40 can also adopt other modes as long as the movement of the electromagnetic array 30 can be achieved.

[0067] In some specific embodiments, the chess playing operation also includes chess pieces 20 entering and exiting the game. In order to place the chess pieces 20 entering and exiting the game, the chessboard 10 includes a chess playing area and a chess piece storage area, wherein the chess playing area is used for chess players to play chess, and the chess piece storage area is used to store the chess pieces 20 entering or exiting the game. Specifically, the chess piece storage area can be set around the chess playing area, or on both sides of the chess playing area.

[0068] In addition, the present invention also discloses a chessboard device control method, which controls the above-mentioned chessboard device, and specifically includes the following steps:

[0069] Step S1, obtaining the initial position, target position and target chess piece;

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

[0071] Step S2, determining the target moving path according to the initial position and the target position;

[0072] The control unit determines the moving path of the target chess piece according to the initial position and the target position of the target chess piece. The moving paths generally include multiple moving paths, and one of the multiple moving paths is selected as the target moving path.

[0073] Step S3, judging whether there is a blocking chess piece on the target moving path, if there is, controlling each electromagnet 31 on the target moving path to be energized in sequence to generate a first magnetic force, controlling the electromagnet 31 corresponding to the blocking chess piece to be energized to generate a second magnetic force, the second magnetic force is different from the first magnetic force, so that the target chess piece moves to the target position in a jumping manner. If there is no blocking chess piece on the target moving path, controlling each electromagnet 31 on the target moving path to be energized in sequence to generate the first magnetic force, so that the target chess piece moves to the target position in a jumping manner.

[0074] The chessboard device control method disclosed in the embodiment of the present invention determines the target moving path according to the initial position and the target position as follows: when there are multiple moving paths, the shortest path is the target moving path; or, when there are multiple moving paths, one path can be designated as the target moving path, and the shortest path is preferably selected as the target moving path.
