[0050] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0051] The following is combined with Figures 1-7 The chess clock and chess playing device provided by the utility model embodiment will be described in detail through specific embodiments and application scenarios.

[0052] In the first aspect, such as Figure 1 , Figure 2 and Figure 5 As shown, this utility model embodiment provides a chess clock 1, including: a housing 10, a control module 11, a communication module 12, and a knob button 13;

[0053] The housing 10 has a receiving cavity, and the control module 11 and the communication module 12 are respectively disposed in the receiving cavity. The control module 11 and the communication module 12 are communicatively connected. The communication module 12 is configured to communicate with the chess robot 2 with the display screen 22. The knob button 13 is disposed in the housing 10 and is electrically connected to the control module 11.

[0054] The knob button 13 is used to receive rotation input to control the movement of the cursor on the display screen 22, or to receive press input to give the cursor a selection instruction or control the game robot 2 to end the timer.

[0055] Understandably, the chess clock 1 can be used in conjunction with a chess-playing robot 2 for playing chess, Go, and Gomoku to enable human-computer interaction. The housing 10 of the chess clock 1 can be configured as a cubic or cylindrical box, without specific limitations.

[0056] The housing 10 may have a first mounting port on its shell wall. The first mounting port is used to install the knobs and buttons 13. It is necessary to ensure that a portion of the knobs and buttons 13 are located outside the housing 10 so that the user can perform rotation and pressing operations on the knobs and buttons 13.

[0057] The control module 11 and the communication module 12 can be integrated on a circuit board. The control module 11 can be a central processing unit (CPU). The communication module 12 can be an Ethernet interface module or a USB interface module to achieve wired communication with the chess robot 2. Alternatively, the communication module 12 can be a WiFi module or a Bluetooth module or other wireless communication module to achieve wireless communication with the chess robot 2.

[0058] For example, the chess robot 2 includes a main control board 21, a robotic arm 24 and a display screen 22. The main control board 21 is communicatively connected to the robotic arm 24 and the display screen 22 respectively. The communication module 12 of the chess clock 1 is communicatively connected to the main control board 21. The main control board 21 is used to control the movement of the robotic arm 24 to pick up and release chess pieces.

[0059] Meanwhile, the display screen 22 has a configuration interface with virtual buttons for selecting game modes. Multiple virtual buttons can be set, each corresponding to a game mode. For example, when playing against the Go robot 2, the main screen of the display screen 22 can display four virtual buttons, whose game modes can be set to "Go Human-Machine Game," "Go Challenge," "Go Human-Human Game," and "Gomoku Human-Machine Game," respectively. Of course, the main screen of the display screen 22 can also display virtual buttons representing other game modes; this is not limited.

[0060] In practical applications, since the rotary button 13, control module 11, communication module 12 and chess robot 2 form a smooth communication link in sequence, when the user performs a rotation input on the rotary button 13, the rotation input received by the rotary button 13 can be represented in real time by the movement of the cursor on the display screen 22. When the user controls the cursor to move to the set position on the display screen 22 through the rotary button 13, for example, when the cursor moves to the virtual button corresponding to the chess mode selected by the user, the user can press the rotary button 13 to confirm the selection instruction of the cursor, that is, by clicking the virtual button with the cursor, the chess robot 2 can control the robotic arm 24 to complete the corresponding chess-playing action according to the chess mode selected by the user.

[0061] For example, when a user plays Go against the AI ​​using the AI ​​2, a Go board 3 is placed between the AI ​​2 and the user. The Go clock 1 can be placed on the user's right side. In this case, according to the orientation of the AI ​​2, the Go clock 1 is located on the left side of the Go board 3. See [link to relevant documentation]. Figure 7 .

[0062] During the game, when the user plays white, after the chess robot 2 completes its move, the display screen 22 of the chess robot 2 starts displaying a countdown, and the player takes over the game. When the user places a white piece and presses the knob button 13, the chess clock 1 sends a clock-striking command to the chess robot 2. The chess robot 2 then controls the display screen 22 to stop the countdown based on the clock-striking command, and the player takes over the game at this time.

[0063] As can be seen from the above, the chess clock 1 shown in this utility model, through the setting of a control module 11, a communication module 12, and a knob button 13 based on the housing 10, allows the control module 11 to send the instructions issued by the user based on the knob button 13 to the chess robot 2 through the communication module 12. This makes it convenient for the user to control the chess robot 2 to perform relevant functions from their seat by using the knob button 13, instead of having to get up and control the chess robot 2 through the display screen 22 every time. This allows for convenient operation of the chess robot 2, improving the convenience of human-computer chess. Furthermore, during the game, the user can also control the clock based on the knob button 13, ensuring that the human-computer chess game meets the chess clock 1 chess game rules of formal competitions. This allows users to pay attention to the rules of the competition while improving their chess skills during training, enhancing their ability to respond to the rules of the competition and achieving the goal of guiding users to play chess in a standardized manner.

[0064] In some embodiments, such as Figure 1 and Figure 4 As shown, the knob button 13 includes: a rotary encoder 131, a connecting rod 132, a trigger switch 133, and an operation knob 134;

[0065] The rotary encoder 131 is electrically connected to the control module 11;

[0066] The connecting rod 132 includes a first rod body 1321 and a second rod body 1322. The first end of the first rod body 1321 is connected to the rotating end of the rotary encoder 131. The second end of the first rod body 1321 is inserted into the first end of the second rod body 1322. The second rod body 1322 can drive the first rod body 1321 to rotate synchronously.

[0067] The trigger switch 133 is located between the second end of the first rod 1321 and the first end of the second rod 1322, and is electrically connected to the control module 11. The operation knob 134 is connected to the second end of the second rod 1322.

[0068] It is understandable that when the user rotates the operation knob 134, the operation knob 134 will drive the first rod 1321 to rotate synchronously through the second rod 1322, and then drive the rotating end of the rotary encoder 131 to rotate based on the first rod 1321, so that the rotary encoder 131 can be used to detect the rotation angle information of the operation knob 134.

[0069] Thus, after the control module 11 sends the rotation angle information detected by the rotary encoder 131 to the chess robot 2 through the communication module 12, the main control board 21 of the chess robot 2 can determine the position information on the cursor based on the rotation angle information, thereby synchronously controlling the cursor to move on the display screen 22, so that the user can control the cursor to move on the display screen 22 by rotating the knob button 13.

[0070] Correspondingly, when the user presses the operation knob 134, the operation knob 134 will transmit the received pressure to the trigger switch 133 through the second lever 1322. The trigger switch 133 will switch its on / off state under the pressure of the second lever 1322, thereby inputting a trigger signal to the control module 11. After the control module 11 sends the trigger signal to the chess robot 2 through the communication module 12, the main control board 21 of the chess robot 2 can control the cursor to determine the chess mode selected by the user according to the trigger signal, so as to achieve the purpose of the user giving the selection command of the cursor by pressing the knob button 13.

[0071] When the Go-playing robot 2 engages in human-computer play according to the game mode selected by the user, if the player is on the user's side, when the user finishes making a move, they can press the operation knob 134 of the knob button 13, which is to execute the clock-beating command on the game clock. The operation knob 134 will press the trigger switch 133 through the second lever 1322. The trigger switch 133 is triggered to input a trigger signal to the control module 11. The control module 11 sends the trigger signal to the Go-playing robot 2 through the communication module 12. The main control board 21 of the Go-playing robot 2 will control the display screen 22 to display the countdown stop according to the trigger signal. At this time, the player switches to the side of the Go-playing robot 2.

[0072] In some embodiments, such as Figure 4 As shown, the second end of the first rod 1321 is provided with a insertion groove, and the first end of the second rod 1322 is inserted into the insertion groove;

[0073] The groove wall of the insertion slot is provided with a first limiting part, and the peripheral wall of the second rod 1322 is provided with a second limiting part. The first limiting part and the second limiting part abut against each other along the circumference of the connecting rod 132 to prevent the first rod 1321 and the second rod 1322 from rotating relative to each other.

[0074] It is understood that by providing a plug-in slot at the second end of the first rod 1321, the trigger switch 133 can be placed in the plug-in slot, and the plug-in setting between the first rod 1321 and the second rod 1322 can be realized. When the second end of the second rod 1322 is subjected to pressure, it can be ensured that the first end of the second rod 1322 can be inserted into the plug-in slot to trigger the trigger switch 133 to switch states.

[0075] To prevent accidental triggering of the trigger switch 133, the insertion slot may be equipped with an elastic element, such as a spring, which abuts against the bottom of the insertion slot and between the first end of the second rod 1322. When the first end of the second rod 1322 is inserted into the insertion slot to a set value, the first end of the second rod 1322 contacts the trigger switch 133 in the insertion slot and triggers the trigger switch 133. However, when the user does not press the operation knob 134, the first end of the second rod 1322 will not contact the trigger switch 133 in the insertion slot due to the elastic force of the elastic element.

[0076] The first limiting part and the second limiting part abut against each other along the circumference of the connecting rod 132, so that the second rod 1322 can drive the first rod 1321 to rotate synchronously; wherein, the first limiting part and the second limiting part can both be configured to extend along the axial direction of the connecting rod 132, the first limiting part can be a groove formed in the groove wall of the insertion slot, and the second limiting part is a protrusion formed in the circumferential wall of the second rod 1322, the protrusion being adapted to the groove.

[0077] In practical applications, the second rod 1322 can be configured as a rod with a "D" shaped cross-section. The shape of the insertion slot is adapted to the shape of the peripheral wall of the second rod 1322. This design facilitates the insertion of the second rod 1322 into the insertion slot of the first rod 1321, and also ensures that the first rod 1321 and the second rod 1322, which are inserted into each other, can rotate synchronously.

[0078] In some embodiments, such as Figure 1 , Figure 3 and Figure 6 As shown, the chess clock 1 also includes a mouse photoelectric sensor 111, which is disposed on the bottom surface of the housing 10 and electrically connected to the control module 11; wherein, the mouse photoelectric sensor 111 is used to detect the movement information of the housing 10 on the plane to control the movement of the cursor on the display screen 22.

[0079] Understandably, the bottom surface of the housing 10 is configured as a flat surface that can contact a horizontal tabletop.

[0080] In some examples, a light-transmitting port can be provided on the bottom surface of the housing 10, and the mouse photoelectric sensor 111 is disposed inside the housing 10. The detection end of the mouse photoelectric sensor 111 is disposed opposite to the light-transmitting port. This design also enables the mouse photoelectric sensor 111 to be disposed on the bottom surface of the housing 10.

[0081] The mouse photoelectric sensor 111 is widely used in existing computer mice to control the movement of the cursor on the computer screen. Specifically, in the application scenario of this application, the mouse photoelectric sensor 111 typically includes a light-emitting element and a photoelectric receiving element. For example, the light-emitting element is a light-emitting diode, and the photoelectric receiving element is a photodiode array or a CMOS sensor. The light emitted by the light-emitting element is reflected and scattered after shining on the plane on the lower side of the housing 10. The photoelectric receiving element is used to receive the reflected light. The mouse photoelectric sensor 111 converts these reflected light rays into electrical signals. The control module 11 analyzes the electrical signals generated by the mouse photoelectric sensor 111 to determine the displacement of the housing 10 in the horizontal and vertical directions, thereby obtaining the movement information of the housing 10 on the plane.

[0082] Since the chess clock 1 is connected to the chess robot 2 via the communication module 12, the movement information of the shell 10 on the plane detected by the mouse photoelectric sensor 111 can be uploaded to the main control board 21 of the chess robot 2 in real time. The main control board 21 will update the position coordinates of the cursor on the display screen 22 in real time according to the movement information of the shell 10, so as to realize the purpose of controlling the movement of the cursor on the display screen 22 by using the mouse photoelectric sensor 111.

[0083] In practical applications, based on the function of the mouse photoelectric sensor 111 to control the cursor to move on the display screen 22, users can easily perform related operations on the display screen 22 when solving Go problems, easily mark on the display screen 22 when reviewing and explaining the game, and also easily perform related touch operations on the display screen 22 by replacing the human hand with the chess clock 1.

[0084] In some embodiments, such as Figure 1 As shown, the chess clock 1 also includes a gyroscope 112, which is disposed in the housing cavity and electrically connected to the control module 11; wherein, the gyroscope 112 is used to detect the movement information of the housing 10 to control the movement of the cursor on the display screen 22.

[0085] Understandably, since the gyroscope 112 is located inside the housing 10, when the user moves the housing 10 in three-dimensional space, the gyroscope 112 moves with the housing 10. The gyroscope 112 will detect the angular velocity of the housing 10's movement. For example, the angular velocities of the X-axis (Pitch) and Z-axis (Yaw) are usually mapped to the movement speed of the housing 10 to obtain the movement information of the housing 10.

[0086] Similar to the principle of the mouse's photoelectric sensor 111 controlling cursor movement, the movement information detected by the gyroscope 112 is uploaded to the main control board 21 of the chess robot 2. The main control board 21 will update the cursor's position coordinates on the display screen 22 in real time according to the movement information of the shell 10, so as to control the movement of the cursor on the display screen 22.

[0087] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the chess clock 1 also includes an indicator light 17, which is electrically connected to the control module 11; when the knob button 13 receives a pressing input, the control module 11 controls the indicator light 17 to flash.

[0088] Understandably, indicator light 17 can be an LED light.

[0089] When the user finishes placing the piece, they will press the knob button 13. At this time, the control module 11 will control the indicator light 17 to flash. Based on whether the indicator light 17 flashes normally, the user can intuitively judge whether the clock-beating command has been issued normally.

[0090] In some embodiments, such as Figure 1 As shown, the chess clock 1 also includes: a power module 114 and a power detection module 113; the power module 114 is electrically connected to the control module 11, and the power detection module 113 is electrically connected to both the power module 114 and the control module 11, and the power detection module 113 is used to detect the remaining power of the power module 114.

[0091] When the remaining power of the power module 114 is lower than the set value, the control module 11 controls the indicator light 17 to flash.

[0092] It is understandable that both the power module 114 and the power detection module 113 are housed inside the housing 10. The power module 114 can be a storage battery, such as a lead-acid battery, a nickel-cadmium battery, or a lithium battery.

[0093] In practical applications, the power detection module 113 can adopt a resistor voltage divider voltage detection circuit, which obtains the remaining power of the power module 114 by detecting the voltage of the power module 114; the power detection module 113 can also use resistors, Hall elements, etc. as current detection elements, which are used to detect the charging / discharging current of the power module 114, and the remaining power of the power module 114 can be calculated based on the cumulative amount of the charging or discharging current of the power module 114.

[0094] When the remaining power of the power module 114 is lower than the set value, it can be determined that the power module 114 is short of power. At this time, the control module 11 controls the indicator light 17 to flash. For example, the control module 11 controls the indicator light 17 to switch on and off at a set frequency to prompt the user to replace the power module 114 or charge the power module 114.

[0095] In some embodiments, such as Figure 1 and Figure 5As shown, the chess clock 1 also includes a home button 14, which is located on the housing 10 and electrically connected to the control module 11. The home button 14 is used to receive press input to control the display content of the display screen 22 to return to the home page.

[0096] Understandably, the main page of the display screen 22 has multiple virtual buttons for selecting the game mode. The home button 14 controls the display content of the display screen 22 to return to the main page, making it convenient for users to select the appropriate game mode according to their actual game needs.

[0097] In some embodiments, such as Figure 1 and Figure 5 As shown, the chess clock 1 also includes a return button 15, which is located in the housing 10 and electrically connected to the control module 11. The return button 15 is used to receive a press input to control the display content of the display screen 22 to return to the previous page.

[0098] It is understandable that the display screen 22 usually displays information in the form of a configuration interface, that is, the display screen 22 can display information through multiple pages. According to the user's operation process, the content displayed on each page is usually different. By using the return button 15, the display content of the display screen 22 can be returned to the previous page, which makes it convenient for the user to read the relevant information on the previous page, or to reconfigure the relevant selection instructions on the previous page.

[0099] In some embodiments, such as Figure 1 and Figure 5 As shown, the chess clock 1 also includes a custom function key 16, which is located in the housing 10 and electrically connected to the control module 11. The custom function key 16 is used to receive press input to control the chess robot 2 to perform the function of the custom function key 16.

[0100] Understandably, users can customize the function key 16 of the Go AI 2 to achieve the desired function. When the user presses the customized function key 16, the Go AI 2 can directly enter a specific function mode, such as "Go AI vs. Gomoku" or "Gomoku AI vs. Gomoku". This design is convenient to meet the needs of users' personal usage habits.

[0101] In the second aspect, such as Figure 1 and Figure 7 As shown, this utility model embodiment also provides a chess playing device, including: a chess robot 2 and a chess clock 1 as described above, wherein the chess clock 1 is communicatively connected to the chess robot 2 through a communication module 12.

[0102] It is understood that since the chess playing device includes a chess clock 1, and the specific structure of the chess clock 1 is as described in the above embodiments, the chess playing device of this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiments, which will not be described in detail here.

[0103] In practical applications, the chess robot 2 is usually used for human-computer chess games such as Go or Chinese chess. The chess robot 2 includes a host and a robotic arm 24. The host is equipped with a main control board 21 and a display screen 22. The first end of the robotic arm 24 is rotatably mounted on the host, and the second end of the robotic arm 24 is equipped with a picking-up part for picking up or releasing chess pieces, such as a pneumatic suction head or a magnetic suction head.

[0104] like Figure 7 As shown, a chessboard 3 is set on the front side of the main unit of the chess robot 2. When the user plays chess, he / she is located on the side of the chessboard 3 away from the main unit. A chess box 4 is placed on the left side of the chessboard 3 and a box lid 5 is placed on the right side of the chessboard 3. When the chess robot 2 is a Go robot, the chess box 4 is provided with a first slot and a second slot. The first slot is used to store black chess pieces and the second slot is used to store white chess pieces. The box lid 5 is used to cover the chess box 4.

[0105] In some embodiments, such as Figure 1 As shown, the chess robot 2 is equipped with a voice prompt module 23, and the display screen 22 is also used to display clock information for the countdown.

[0106] When the knob button 13 receives a press input to control the chess robot 2 to end the countdown, the voice prompt module 23 issues a voice prompt, and the display screen 22 shows that the countdown has stopped.

[0107] Understandably, the voice prompt module 23 can use a buzzer or a speaker.

[0108] When the user finishes placing a piece, they will press the knob button 13 to issue a clock-striking command. The main control board 21 of the chess robot 2 will control the display screen 22 to show the countdown to stop according to the clock-striking command, and control the voice prompt module 23 to issue a voice prompt, such as the voice prompt module 23 issuing a "beep" sound to prompt the user to switch to the side of the chess robot 2.

[0109] Of course, when the chess robot 2 finishes making its move, the main control board 21 of the chess robot 2 can also control the display screen 22 to display the countdown and control the voice prompt module 23 to issue a voice prompt to remind the player to switch to the user's side.
