Description

Technical Field

[0001] This utility model relates to the field of toy technology, specifically to a chess-like toy. Background Technology

[0002] In existing technologies, display modules for smart hardware typically utilize touchscreen solutions. However, due to the prohibitive cost of custom screens in toys, on-screen buttons often employ capacitive touch switches to sense hand touch. A touch switch is an electronic device that controls circuitry through human contact or proximity. A capacitive touchscreen button primarily consists of a capacitive sensor chip, a control circuit communicating with the sensor chip, and sensing electrodes corresponding to each of the multiple squares on a chessboard. The sensor chip is configured to sense the electric field signal of the sensing electrodes, and the control circuit processes this signal. When a user touches a sensing electrode, the electric field on that electrode changes, and the sensor chip detects this change using analog circuitry. Therefore, the capacitive touchscreen button module uses touch sensing, eliminating the need for physical pressing; a simple touch triggers a response.

[0003] Existing capacitive touchscreens use springs as sensing electrodes. However, due to their elasticity and large deformation, springs are prone to uneven height, making it difficult to maintain consistent electromagnetic induction intensity for each button. This results in varying sensitivity for each button, affecting the accuracy and stability of touch sensing, and consequently impacting the user experience.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0049] See Figures 1 to 7 As shown, this application embodiment provides a chess toy, including a shell 1, a chessboard shell 2, a circuit board 3, a light-shielding plate 4, and a chess piece information input module. The shell 1 has a cavity and an opening communicating with the cavity. The chessboard shell 2 is connected to the shell 1 and covers the opening. The chessboard shell 2 has multiple chess positions. The circuit board 3 is disposed within the cavity and has multiple lamps 6, each lamp 6 corresponding to a specific chess position. The light-shielding plate 4 is disposed within the cavity and between the circuit board 3 and the chessboard shell 2. The light-shielding plate 4 has multiple light-transmitting holes 431 and multiple slots 432. Each light-transmitting hole 431 corresponds to a specific lamp 6, and each slot 432 is disposed around the periphery of the corresponding light-transmitting hole 431. The slots 432 are located on the side of the light-shielding plate 4 facing the chessboard shell 2. When the lamp 6 is lit, light passes through the light-transmitting holes 431 and illuminates the chessboard shell 2. The chess piece information input module is disposed within the cavity. The module includes a capacitive sensor chip, a control circuit, and multiple sensing electrodes 5. The capacitive sensor chip and the control circuit are both disposed on the circuit board 3 and electrically connected. Each sensing electrode 5 has a sensing element 51 and an extension element 52. The sensing element 51 is embedded in a corresponding slot 432. One end of the extension element 52 is connected to the sensing element 51, and the other end is connected to the circuit board 3. The capacitive sensor chip on the circuit board 3 is used to sense changes in the electric field of the sensing electrode 5. The control circuit is used to control each of the lamp bodies 6.

[0050] The chess-like toy provided in this application achieves a stable connection between the sensing electrode 5 and the circuit board 3 by embedding the sensing plate 51 of the sensing electrode 5 into the groove 432 of the light-shielding plate 4 and connecting it to the circuit board 3 using the extension plate 52. Simultaneously, the groove 432 on the light-transmitting plate limits the position of the sensing electrode 5, avoiding the height inconsistency problem caused by elastic deformation of traditional spring sensing electrodes 5. This design ensures that the height of each sensing electrode 5 is consistent, thereby maintaining a consistent electromagnetic induction intensity, which improves the accuracy and stability of touch sensing and provides players with a smoother and more enjoyable gaming experience.

[0051] The chess-like toy provided in this application has an extension 52 of the sensing electrode 5 electrically connected to a circuit board 3 and a capacitive sensor chip. The capacitive sensor chip senses the electric field signal of the sensing electrode 5, and a control circuit processes the electric field signal. More specifically, the capacitive sensor chip typically consists of a microprocessor and analog circuitry. The control circuit is triggered by detecting capacitance changes caused by human contact. When a user touches the sensing electrode 5, the electric field on the sensing electrode 5 changes, and the capacitive sensor chip can detect this change in electric field using analog circuitry. More specifically, the control circuit is configured to receive and process the signals transmitted by the capacitive sensor chip. The control circuit can consist of digital and logic circuits, and achieves touch operation by processing the electric field change signal generated by the sensing electrode 5. Thus, the capacitive touch button module uses touch sensing, eliminating the need for physical pressing; a light touch triggers the response. Upon receiving the touch signal, the control circuit controls the corresponding lamp 6 to light up or turn off.

[0052] Furthermore, the light-transmitting hole 431 on the light-shielding plate 4 not only provides a light channel for the lamp body 6, but also effectively prevents light leakage through the baffle 45, further enhancing the visual effect of the chess game. The chessboard shell 2 can be equipped with crisscrossing ribs to divide it into multiple chess positions, or it can be without ribs, with the chess positions distinguished by the illumination of the lamp body 6.

[0053] In some possible implementations, the groove 432 can be a closed ring, surrounding the edge of the light-transmitting hole 431, and the sensing sheet 51 is a ring-shaped sheet embedded in the groove 432. Both the sensing sheet 51 and the groove 432 are designed as closed rings. This design increases the sensing area, improves the accuracy and stability of sensing, and ensures that the sensing sheet 51 is fully and securely embedded in the groove 432, resulting in a tighter and more stable connection between the sensing electrode 5 and the light-shielding plate 4.

[0054] In some possible implementations, a clearance hole 433 is provided on the bottom wall of the recess 432. With the sensing piece 51 attached to the bottom wall of the recess 432, the extension piece 52 passes through the clearance hole 433 to connect to the circuit board 3. This design ensures the stable placement of the sensing piece 51 within the recess 432 and provides a convenient channel for the connection between the extension piece 52 and the circuit board 3, making the entire circuit connection structure more compact and reasonable.

[0055] In some possible implementations, the bottom wall of the recess 432 has at least two clearance holes 433, which are spaced apart sequentially along the circumference of the recess 432. The sensing electrode 5 has at least two extension pieces 52, which are spaced apart sequentially along the circumference of the sensing piece 51. The sensing piece 51 is embedded in the recess 432, and each extension piece 52 passes through a corresponding clearance hole 433. This design of multiple extension pieces 52 and multiple clearance holes 433 further enhances the stability of the connection between the sensing electrode 5 and the circuit board 3, and also helps to improve the sensing electrode 5's ability to capture and transmit touch signals. If one of the extension pieces 52 accidentally disconnects from the circuit board 3, the signal can still be transmitted.

[0056] In actual production, the included angle between the sensing plate 51 and the extension plate 52 can be slightly greater than 90° or slightly less than 90°. This way, after the extension plate 52 is inserted into the clearance hole 433, the extension plate 52 will abut against the inner wall of the clearance hole 433, ensuring a stable initial connection between the sensing electrode 5 and the light-shielding plate 4. Then, the extension plate 52 is soldered to the circuit board 3. This improves installation efficiency and effectiveness.

[0057] Furthermore, the side of the extension piece 52 facing away from the sensing piece 51 is a convex arc shape. The arc shape serves as a guide, making it easier to position the extension piece 52 when it is inserted into the clearance hole 433, thus making the insertion more convenient.

[0058] In some possible implementations, the clearance hole 433 is provided on one side of the outer edge of the bottom wall of the groove 432, and the extension piece 52 is provided on the peripheral edge of the sensing sheet 51. With this configuration, the sensing electrode 5 can be manufactured by integrally molding the sensing sheet 51 and the extension piece 52, and then forming the final shape through bending. This results in high overall strength of the sensing electrode 5 and a simple manufacturing process. The optimal position of the groove 432 corresponding to the placement of the extension piece 52 is at the outer edge of the bottom wall of the groove 432.

[0059] In some possible implementations, the extension piece 52 has a bent piece 53 on the side opposite to the sensing piece 51, and the bent piece 53 is approximately parallel to the sensing piece 51. The extension piece passes through the clearance hole, and the bent piece 53 is positioned on the side of the circuit board 3 opposite to the sensing piece 51, and is soldered to the contacts on the circuit board 3. The bent piece further serves to precisely position the extension piece, ensuring that the sensing electrode 5 is at a consistent height from the circuit board, resulting in higher sensing consistency. Simultaneously, this design makes the connection between the extension piece and the circuit board more stable. The bent piece provides additional fixing, preventing the extension piece from loosening or shifting during soldering or use, thereby ensuring the stability of signal transmission between the sensing electrode and the circuit board. The approximately parallel alignment of the bent piece with the sensing piece also facilitates automated soldering operations on the circuit board, improving production efficiency.

[0060] In some possible implementations, the light-shielding plate 4 includes a base plate 41 and a plurality of cylindrical bodies 42 disposed on the base plate 41. The cylindrical bodies 42 are located on one side of the base plate 41 along its thickness direction, and an end plate 43 is disposed on the side of the cylindrical body 42 opposite to the base plate 41. The end plate 43 is provided with the light-transmitting hole 431 and the groove 432. The cylindrical bodies 42 can accommodate components such as the extension piece 52 and the lamp body 6, providing a reasonable layout space for the internal structure of the entire chess game. At the same time, the presence of the cylindrical bodies 42 also enhances the structural strength of the light-shielding plate 4, making it less prone to deformation under external forces, thus ensuring the stability and durability of the chess game.

[0061] In some possible implementations, reinforcing ribs 44 are provided on the base plate 41, and the reinforcing ribs 44 connect each of the cylinders 42. The provision of reinforcing ribs 44 can enhance the overall strength and stability of the light shield 4, making it less prone to deformation or damage during the application of certain external forces or long-term use, thereby ensuring the normal use of the chess game.

[0062] In some possible implementations, the light-transmitting hole 431 can be any one or a combination of various shapes such as star, triangle, polygon, heart, and circle. Different shapes of the light-transmitting hole 431 can bring diverse visual effects to board games, satisfying the personalized appearance needs of different players and improving the overall aesthetics and fun.

[0063] In some possible implementations, a baffle 45 is provided on the side of the end plate 43 facing the circuit board 3. The baffle 45 extends along the edge of the light-transmitting hole 431 and is close to or attached to the circuit board 3. The lamp body 6 on the circuit board 3 is located inside the baffle 45. The baffle 45 can effectively block the light emitted by the lamp body 6 from scattering in other directions, avoiding light crosstalk, and also makes the light more concentrated through the light-transmitting hole 431 to illuminate the corresponding position of the chessboard shell 2, thereby improving the display effect and visual experience of the chess game.

[0064] In some possible implementations, the light-shielding plate 4 is provided with a plurality of positioning posts 46, and the circuit board 3 is provided with a plurality of insertion holes 31, with each positioning post 46 inserted into a corresponding insertion hole 31. The cooperative design of the positioning posts 46 and the insertion holes 31 enables the light-shielding plate 4 and the circuit board 3 to be quickly and accurately positioned and installed when assembling the chess game, improving assembly efficiency and accuracy, and also enhancing the stability of the connection between the two.
