[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Combine the following Figure 1-Figure 4 , the chess pieces and chess-playing device provided by the embodiment of the utility model are described in detail through specific embodiments and their application scenarios.

[0039] In the first aspect, Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a chess piece 1, comprising: a light-transmitting shell 11, an electromagnetic induction element 12, a control module 13, a light-emitting element 14 and a battery module 15.

[0040] The electromagnetic induction element 12 , the control module 13 , the light-emitting element 14 and the battery module 15 are respectively disposed in the light-transmitting housing 11 .

[0041] The battery module 15 is used to provide working power for the electromagnetic induction element 12 , the control module 13 and the light-emitting element 14 . The electromagnetic induction element 12 and the control module 13 are electrically connected, and the control module 13 and the light-emitting element 14 are electrically connected.

[0042] The electromagnetic induction element 12 is used to feed back a trigger signal to the control module 13 under the action of a magnetic field, and the control module 13 is used to control the light-emitting state of the light-emitting element 14 according to the trigger signal.

[0043] It is understandable that the light-transmitting housing 11 has the property of being at least partially light-transmitting or fully light-transmitting. The light-transmitting housing 11 can be made of light-transmitting materials such as plastic and glass, and the light-transmitting materials are doped with relevant coloring materials. When the light-emitting element 14 is in a power-off state, the light-transmitting housing 11 only displays a first color, which is the color of the coloring material. When the light-emitting element 14 is in a power-on state, the light-transmitting housing 11 can display a second color under the stimulation of the light emitted by the light-emitting element 14, and the second color is different from the first color. Among them, the first color can be black, and the second color can be white.

[0044] Of course, the light-transmitting shell 11 can also be made entirely of transparent materials, for example, the light-transmitting shell 11 can be a transparent PVC shell. The light-transmitting shell 11 can display different brightness according to the luminous state of the light-emitting element 14, which is equivalent to realizing the switching of the color of the chess piece 1 to a certain extent.

[0045] The light emitting element 14 may be an LED lamp known in the art. Optionally, the light emitting element 14 may be a point light source or a line light source based on an LED lamp; optionally, the LED lamp may be a white light LED lamp. Optionally, the light emitting element 14 may also be an LED three-primary color lamp, and the control module 13 may control the LED three-primary color lamp to display different colors according to the received trigger signal.

[0046] The electromagnetic induction element 12 may be a passive coil, a Hall sensor, etc., which are well known in the art, and there is no specific limitation thereto. As long as the functional device can output a trigger signal under the action of a magnetic field, the design requirements are met.

[0047] The control module 13 may be a single chip microcomputer, a central processing unit (CPU) or a switch device known in the art. The control module 13 can control the power-on state of the light-emitting element 14 according to a trigger signal, thereby controlling the light-emitting state of the light-emitting element 14 .

[0048] The battery module 15 can be configured as a button battery, or the battery module 15 can be a rechargeable component composed of a charging coil and a lithium battery to achieve wireless charging of the battery module 15 and ensure the performance of the chess piece 1.

[0049] For the chess piece 1 shown in the utility model, by arranging the electromagnetic induction element 12, the control module 13, the light-emitting component 14 and the battery module 15 in the light-transmitting shell 11, the chess piece 1 can be directly placed in the magnetic field environment at the end of the game, and the electromagnetic induction element 12 will feedback the trigger signal to the control module 13 under the action of the magnetic field, and the control module 13 can control the light-emitting component 14 to turn on or off according to the trigger signal, and the light-transmitting shell 11 will display the corresponding color according to the opening and closing state of the light-emitting component 14, so that each chess piece 1 can automatically change color under the action of the magnetic field and switch to a consistent color, so that at the end of the game, there is no need for the chess robot 5 to sort the chess pieces 1, which simplifies the operation of collecting pieces and improves the efficiency of chess playing.

[0050] In some embodiments, the electromagnetic induction element 12 is a Hall sensor; the Hall sensor is used to feedback a rising edge signal to the control module 13 under the action of a first polarity magnetic field, and to feedback a falling edge signal to the control module 13 under the action of a second polarity magnetic field.

[0051] The control module 13 is used to control the switch state of the light emitting element 14 according to the rising edge signal and the falling edge signal.

[0052] It is understandable that the control module 13 can selectively control the switch state of the light emitting element 14 according to the type of the trigger signal fed back by the Hall sensor.

[0053] Optionally, when the trigger signal received by the control module 13 is a rising edge signal, the control module 13 can control the light-emitting element 14 to be in an on state; when the trigger signal received by the control module 13 is a falling edge signal, the control module 13 can control the light-emitting element 14 to be in an off state.

[0054] In practical applications, when the chess piece 1 shown in this embodiment is a Go chess piece, two chess boxes 2 can be configured for the Go chess piece, and the two chess boxes 2 can be a first chess box and a second chess box, and a first polarity magnetic field is set in the first chess box, and a second polarity magnetic field is set in the second chess box. The first polarity magnetic field can be an N-polar magnetic field, and the second polarity magnetic field can be an S-polar magnetic field.

[0055] Thus, after the game is over, when the Go pieces of different colors are placed in the first chess box, under the action of the first polarity magnetic field, the light-emitting components 14 of each Go piece are turned on, so that each Go piece in the first chess box displays the first color.

[0056] Correspondingly, when the Go pieces of different colors are placed in the second chess box, under the action of the second polarity magnetic field, the light-emitting components 14 of each Go piece are in a closed state, so that each Go piece in the second chess box displays the second color.

[0057] In some embodiments, Figure 2 As shown, the control module 13 includes a trigger.

[0058] The Hall sensor is electrically connected to a first input terminal of the trigger, the light emitting element 14 is electrically connected to a second input terminal of the trigger, and the output terminal of the trigger is electrically connected to the light emitting element 14 .

[0059] It is understandable that, since the luminous state of the luminous element 14 determines the color state of the chess piece 1, the trigger can perform logical judgment based on the trigger signal fed back by the Hall sensor and the current color state of the chess piece 1 to control the switching of the luminous state of the luminous element 14.

[0060] The trigger truth table shown in this embodiment is shown in Table 1 below:

[0061] Table 1: Flip-flop truth table

[0062] D <![CDATA[Q n ]]> <![CDATA[Q n+1 ]]> 0 0 0 0 1 0 1 0 1 1 1 1

[0063] In the above truth table, D represents the type of trigger signal fed back by the Hall sensor, Q n Indicates the current switch state of the light emitting element 14, Q n+1 It indicates the switch state of the light emitting element 14 under the control of the trigger when the trigger receives the next trigger signal.

[0064] When D=0, it means that the Hall sensor does not feedback the trigger signal; when D=1, it means that the Hall sensor feedbacks the trigger signal;

[0065] When Q n = 0, indicating that the light-emitting element 14 is currently in a non-lighting state; when Q n =1, indicating that the light-emitting element 14 is currently in the light-emitting state;

[0066] When Q n+1 = 0, it means that when the trigger receives the next trigger signal, the trigger controls the light-emitting element 14 to be in a non-luminous state; when Q n+1 =1, it means that when the trigger receives the next trigger signal, the trigger controls the light-emitting element 14 to be in a light-emitting state.

[0067] The following chess piece 1 is a Go chess piece as an example, and combined with the first chess box and the second chess box shown in the above embodiment, the trigger shown in this embodiment controls the color of the Go chess piece in detail. When the light-emitting element 14 is not emitting light, the Go chess piece is displayed in black; when the light-emitting element 14 is emitting light, the Go chess piece is displayed in white.

[0068] When a black Go piece (true value is 1) is placed in the first chess box with the first polarity magnetic field, the Hall sensor will feedback a rising edge signal (true value is 1) to the trigger, the trigger outputs a high level (true value is 1), the Go piece appears black, and its color remains unchanged; when a white Go piece (true value is 0) is placed in the first chess box with the first polarity magnetic field, the Hall sensor will feedback a rising edge signal (true value is 1) to the trigger, the trigger outputs a high level (true value is 1), and the color of the Go piece switches from white to black.

[0069] When a black Go piece (true value is 1) is placed in the second chess box with a second polarity magnetic field, the Hall sensor will feedback a falling edge signal (true value is 0) to the trigger, the trigger outputs a low level (true value is 0), and the color of the Go piece switches from black to white; when a white Go piece (true value is 0) is placed in the second chess box with a second polarity magnetic field, the Hall sensor will feedback a falling edge signal (true value is 0) to the trigger, the trigger outputs a low level (true value is 0), the Go piece displays white, and its color remains unchanged.

[0070] In some embodiments, Figure 2 As shown, the chess piece 1 further comprises a circuit board 16 .

[0071] The circuit board 16 is disposed in the light-transmitting housing 11 , and the electromagnetic induction element 12 , the control module 13 , the light-emitting element 14 and the battery module 15 are respectively integrated on the circuit board 16 .

[0072] It is understandable that the circuit board 16 can be a printed circuit board 16 (PCB) known in the art, and the circuit built into the printed circuit board 16 can be used to achieve circuit connection between the electromagnetic induction element 12, the control module 13, the light-emitting element 14 and the battery module 15.

[0073] At the same time, this embodiment integrates the electromagnetic induction element 12 , the control module 13 , the light-emitting element 14 and the battery module 15 on the circuit board 16 , which is also conducive to the installation and removal of the entire set of electrical components relative to the light-transmitting housing 11 .

[0074] In some embodiments, in the application scenario where the chess piece 1 is configured as a Go chess piece, the light-transmitting shell 11 is a black shell that can transmit light, for example, the light-transmitting shell 11 is a PVC shell doped with carbon black; the light-emitting element 14 is used to emit white light, for example, the light-emitting element 14 is a white light LED lamp.

[0075] When the light emitting element 14 is in a power-off state, the black shell appears black; when the light emitting element 14 is in a power-on state, the black shell appears white or grayish white.

[0076] In some embodiments, Figure 1 and Figure 2 As shown, the light-transmitting housing 11 includes a first housing 1101 and a second housing 1102 .

[0077] The first shell 1101 and the second shell 1102 are detachably connected, and a receiving cavity is defined between the first shell 1101 and the second shell 1102; the electromagnetic induction element 12, the control module 13, the light-emitting element 14 and the battery module 15 are respectively arranged in the receiving cavity.

[0078] It is understandable that the first shell 1101 and the second shell 1102 are both in a cap shape, and the port of the first shell 1101 and the port of the second shell 1102 are spliced ​​together to assemble the light-transmitting shell 11 .

[0079] In this embodiment, the light-transmitting housing 11 is configured as a first housing 1101 and a second housing 1102 that can be assembled, so that the relevant electrical components in the chess piece 1 can be easily installed and disassembled.

[0080] In the application scenario where the chess piece 1 is configured as a Go chess piece, the first shell 1101 and the second shell 1102 are symmetrically arranged relative to the horizontal symmetry plane of the light-transmitting shell 11 .

[0081] In some examples, to facilitate the detachable connection between the first shell 1101 and the second shell 1102, the first shell 1101 is provided with a first threaded structure, the second shell 1102 is provided with a second threaded structure, and the first threaded structure and the second threaded structure are threadedly connected.

[0082] In which, when the first shell 1101 and the second shell 1102 are both in the shape of a cap, the first threaded structure is an internal thread arranged at the port of the first shell 1101, and the second threaded structure is an external thread arranged at the port of the second shell 1102, and the first shell 1101 and the second shell 1102 are threadedly connected via the first threaded structure and the second threaded structure.

[0083] In some examples, to facilitate the detachable connection between the first shell 1101 and the second shell 1102, the first shell 1101 is provided with a first snap-fit ​​structure, the second shell 1102 is provided with a second snap-fit ​​structure, and the first snap-fit ​​structure and the second snap-fit ​​structure are snap-fitted to each other.

[0084] Among them, when the first shell 1101 and the second shell 1102 are both in the shape of a cap, the first snap-fitting structure is a snap-fitting groove arranged at the port of the first shell 1101, and the second snap-fitting structure is a snap-fitting tongue arranged at the port of the second shell 1102, and the snap-fitting tongue can be inserted into the snap-fitting groove so that the first shell 1101 and the second shell 1102 are snap-fitted through the first snap-fitting structure and the second snap-fitting structure.

[0085] In the second aspect, Figure 3 As shown, an embodiment of the utility model further provides a chess-playing device, comprising: a chess box 2, a magnetic member 3 and the chess piece 1 as described above.

[0086] The magnetic member 3 is arranged in the chess box 2 to form a magnetic field environment in the chess box 2; the chess piece 1 is contained in the chess box 2 and is in the magnetic field environment.

[0087] The magnetic part 3 can be arranged at the bottom of the chess box 2. The magnetic part 3 can be a permanent magnet known in the art or an electromagnet, and no specific limitation is made to this.

[0088] Since the chess-playing device includes the chess piece 1, and the specific structure of the chess piece 1 refers to the above embodiment, the chess-playing device of this embodiment includes all the technical solutions of the above embodiment, and therefore has at least all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be described one by one here.

[0089] In some embodiments, the magnetic member 3 includes a first magnet, and the first magnet is used to form a first polarity magnetic field in the chess box 2.

[0090] Alternatively, the magnetic member 3 includes a second magnet, and the second magnet is used to form a second polarity magnetic field in the chess box 2.

[0091] It is understandable that multiple first magnets can be set, and multiple first magnets are arranged side by side at the bottom of the chess box 2, and the N pole of the first magnet is arranged upward and the S pole is arranged downward, so that a first polarity magnetic field can be formed in the chess box 2, and the first polarity magnetic field is an N pole magnetic field.

[0092] Correspondingly, multiple second magnets can be arranged side by side at the bottom of the chess box 2, and the N pole of the second magnet is arranged downward and the S pole is arranged upward, so that a second polarity magnetic field can be formed in the chess box 2, and the second polarity magnetic field is an S pole magnetic field.

[0093] At the same time, the chess box 2 can be configured to include a first chess box and a second chess box, the first magnet is arranged in the first chess box to form a first polarity magnetic field in the first chess box; the second magnet is arranged in the second chess box to form a second polarity magnetic field in the second chess box.

[0094] As described in the above embodiments, in the application scenario where the chess piece 1 is configured as a Go chess piece, when Go chess pieces of different colors are stored in a first chess box, under the action of a first polarity magnetic field, the colors of the Go chess pieces in the first chess box are uniformly switched to black; when Go chess pieces of different colors are stored in a second chess box, under the action of a second polarity magnetic field, the colors of the Go chess pieces in the second chess box are uniformly switched to white.

[0095] In some embodiments, Figure 4As shown, the chess-playing device further includes a chess board 4 and a chess-playing robot 5 ; the chess-playing robot 5 is used to pick up chess pieces 1 from the chess box 2 and perform chess-playing operations based on the chess board 4 .

[0096] It is understandable that the chess-playing robot 5 includes a robot body, a mechanical arm, a piece-retrieving claw and a temporary storage; the base of the mechanical arm is connected to the robot body, and the execution end of the mechanical arm is respectively connected to the piece-retrieving claw and the temporary storage.

[0097] The picking claw is used to pick up the chess piece 1 from the chess box 2 and place the chess piece 1 on the chessboard 4; the temporary storage is arranged on one side of the picking claw, and the temporary storage is used to temporarily store the chess piece 1 picked up by the picking claw.

[0098] The robot body is provided with a camera, a human-machine interaction module and a controller. The camera and the human-machine interaction module are electrically connected to the controller respectively, and the controller is electrically connected to the mechanical arm and the piece-taking claw respectively. The camera is used to identify the changes in the chess game on the chessboard 4 and the position of the user's chess piece; the human-machine interaction module is used to realize the information exchange between the chess-playing robot 5 and the user. Among them, the human-machine interaction module can be a touch screen.

[0099] At the same time, a mounting platform is provided at the front side of the robot body, and the base of the mechanical arm is provided on the mounting platform. The mounting platform is exposed, so that the range of motion of the mechanical arm is increased; the mechanical arm can be a multi-axis mechanical arm, so that the execution end of the mechanical arm can reach various positions on the upper side of the chessboard 4 based on the posture change of the mechanical arm.

[0100] Among them, this embodiment temporarily stores the chess piece 1 picked up by the chess piece retrieval claw through the temporary storage unit, which can effectively reduce the number of times the robot arm moves between the chess piece placement point and the chess piece retrieval point.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
