[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0021] Examples, such as Figures 1-4 As shown, an intelligent chessboard includes a circuit board 9. A battery 5 and an LED light 8 are mounted on the upper part of the circuit board 9. A soft magnetic sheet 6 is bonded to the upper part of the circuit board 9, and a PC sheet 16 is bonded to the lower part. A PET film 1 is bonded to the upper part of the soft magnetic sheet 6, with a chessboard grid pattern on the PET film 1. The circuit board 9 includes an intelligent chess piece recognition circuit, an antenna matrix, a main control MCU, and a power supply circuit. The soft magnetic sheet 6 bonded to the upper part of the circuit board 9, along with the fact that the chess pieces are made of wound inductors containing iron, enables the chess pieces to be attracted and maintains a flat chessboard. The PC sheet 16 bonded to the lower part of the circuit board 9 makes the overall structure aesthetically pleasing and provides a good feel. The PC sheet 16 also protects the bottom of the circuit board 9, extending its lifespan. The PET film 1 with the chessboard grid pattern bonded to the upper part of the soft magnetic sheet 6 is both attractive and unique. The thinnest part of the entire device is only 3.5mm. It is much thinner and lighter than other products on the market, while being highly functional. Each chessboard has an indicator light, and the chess pieces can be magnetically attached, making it easy for staff to carry. It also provides a good user experience.
[0022] It should be noted that the material of circuit board 9 is FR4 circuit board, with a thickness of 1.6mm or more, and sufficient hardness and strength. It serves as both an electronic functional board and a structural support body.
[0023] like Figures 1-2As shown, furthermore, several light slots 7 are formed on the soft magnetic sheet 6, and the positions and vectors of the light slots 7 and LED lights 8 are corresponding. The LED lights 8 are located inside the light slots 7. A silicone light guide post 4 is fixedly installed on the upper end of the circuit board 9. The silicone light guide post 4 and the LED lights 8 are located on the same plane and above the LED lights 8. By forming several light slots 7 on the soft magnetic sheet 6 and having the LED lights 8 located inside the light slots 7, each checkerboard square can be lit when the LED lights 8 are powered on, providing a good user experience. By setting the silicone light guide post 4, the light emitted by the LED lights 8 can be conducted and diffused through the silicone light guide post 4, making the output light softer and more uniform, avoiding glare or excessive brightness in some areas. At the same time, the high light transmittance and low light absorption characteristics of silicone can effectively reduce light loss during transmission and improve light efficiency.
[0024] like Figures 1-2 As shown, further, the upper half of the circuit board 9 is provided with a plastic shell 2, on which a button groove 201 and a light guide groove 202 are provided. The light guide groove 202 and the silicone light guide 4 are positioned and numbered accordingly. The silicone light guide 4 is located inside the light guide groove 202. A silicone button 3 is provided inside the button groove 201. By providing a button groove 201 and a light guide groove 202 on the plastic shell 2, the positions of the silicone button 3 and the silicone light guide 4 can be limited, preventing displacement of the silicone button 3 and the silicone light guide 4 after long-term use.
[0025] like Figure 2 As shown, further, a fixing plate 11 is provided on the upper half of the circuit board 9. Both the fixing plate 11 and the circuit board 9 have threaded holes 10. Bolts 12 are threadedly connected to the threaded holes 10. A fixing block 13 is fixedly installed on one end of the fixing plate 11. Sliding blocks 14 are provided on both sides of the fixing block 13. The sliding blocks 14 are slidably connected to the fixing block 13 by springs 15. By setting the fixing plate 11 to be connected to the circuit board 9 by bolts 12, it is easy to replace the device on the fixing plate 11 when it malfunctions. Sliding blocks 14 are slidably set on both ends of the fixing block 13. The upper half of the sliding blocks 14 has curved surfaces on both sides. There is space between the sliding blocks 14 and the fixing plate 11 to accommodate the roller 18.
[0026] like Figure 4As shown, furthermore, a connecting plate 171 is threadedly connected to the inner wall of the housing 2. A connecting block 17 is fixedly installed on the connecting plate 171. A rotating rod 19 is rotatably connected to one end of the connecting block 17. A roller 18 is rotatably connected to the rotating rod 19. When the housing 2 is connected to the circuit board 9, the roller 18 will initially contact the sliding block 14 and compress the sliding block 14. At this time, the spring 15 is in a compressed state. When the housing 2 and the circuit board 9 continue to connect, the roller 18 will contact the arc surface of the sliding block 14 and the roller 18 will... Roll until roller 18 contacts fixed plate 11. At this time, sliding block 14 returns to its original state by the elastic force of spring 15. At this time, roller 18 is located between fixed plate 11 and sliding block 14, and plastic shell 2 is connected to circuit board 9. When it is necessary to separate plastic shell 2 from circuit board 9, slide plastic shell 2 away from circuit board 9. Roller 18 will contact the arc surface of sliding block 14 and squeeze sliding block 14, so that roller 18 can slide out between fixed plate 11 and sliding block 14, and then plastic shell 2 and circuit board 9 can be separated.
[0027] In this embodiment, as Figures 1-4 As shown in the figure, the principle of the intelligent chessboard provided in this embodiment is as follows: By setting up circuit board 9, which contains intelligent chess piece recognition circuitry, an antenna matrix, a main control MCU, and a power supply circuit, and by attaching a soft magnetic sheet 6 to the upper part of circuit board 9, and by using iron-containing wound inductors for the chess pieces, the device achieves chess piece adsorption and maintains a flat chessboard. A PC sheet 16 is attached to the lower part of circuit board 9, resulting in an aesthetically pleasing structure and a good feel. The PC sheet 16 also protects the bottom of circuit board 9, extending its lifespan. A PET film 1 printed with a chessboard pattern is attached to the upper part of the soft magnetic sheet 6, adding to the device's attractiveness and unique design. The thinnest part of the entire device is only 3.5mm. It is much thinner and lighter than other products on the market, while being highly functional. Each chess square has an indicator light, and the chess pieces can be magnetically attached, making it easy for staff to carry. It also provides a good user experience. When the housing 2 is connected to the circuit board 9, the roller 18 will initially contact the sliding block 14 and squeeze the sliding block 14. At this time, the spring 15 is in a compressed state. When the housing 2 and the circuit board 9 continue to connect, the roller 18 will contact the curved surface of the sliding block 14 and the roller 18 will roll until the roller 18 contacts the fixing plate 11. At this time, the sliding block 14 will return to its original shape due to the elastic force of the spring 15. At this time, the roller 18 is located between the fixing plate 11 and the sliding block 14, and the housing 2 and the circuit board 9 are connected.
