Technical Field
[0001] This utility model belongs to the field of chessboard technology, and specifically refers to a folding chessboard. Background Technology
[0002] The chessboard, as an important medium for various board games, occupies an important place in people's lives. Two people, as opposing teams, play against each other on the chessboard, enriching daily entertainment and intellectual development. Existing chessboards are usually flat boards with marked paths for placing or moving pieces. These boards cannot be folded, resulting in a large size and inconvenience for carrying. Therefore, foldable chessboards have emerged on the market, divided in the middle and connected by hinges. However, this connection method requires screws to attach the hinges to the boards. During frequent opening and closing, the connection points are constantly subjected to stress, and over time, the screws on the hinges may loosen, leading to a loose connection between the hinges and the boards. Therefore, there is a need for a foldable chessboard that can be folded without hinges. Summary of the Invention
[0003] The purpose of this invention is to provide a folding chessboard with a simple structure that can be folded without hinges.
[0004] The purpose of this utility model is achieved as follows:
[0005] A folding chessboard includes a left chessboard and a right chessboard that can be folded or unfolded relative to each other. Each chessboard has pressable chess pieces. An electronic display component is installed within each chessboard; pressing a chess piece illuminates it. A connecting member is provided between the left and right chessboards. The left and right chessboards are rotatably connected to the connecting member and can rotate around it. The connecting member has a first rotating hole and a second rotating hole, each containing a first rotating shaft and a second rotating shaft. The left chessboard is rotatably connected to the connecting member via the first rotating shaft and can rotate around it. The right chessboard is rotatably connected to the connecting member via the second rotating shaft and can rotate around it. At this point, the left and right chessboards are completely folded and rotated.
[0006] Furthermore, the left chessboard is provided with a first rotating tooth, and the right chessboard is provided with a second rotating tooth. The first rotating tooth and the second rotating tooth are arranged adjacent to each other and mesh with each other. When the left chessboard and the right chessboard are driven to rotate relative to each other around the first rotating axis and the second rotating axis respectively, the first rotating tooth and the second rotating tooth can mesh with each other and rotate.
[0007] Furthermore, the connector is also provided with a first smooth part and a second smooth part, which are respectively located at both ends of the connector. The left chessboard and the right chessboard are respectively provided with a first ring part and a second ring part. The first smooth part and the first ring part abut against each other, and the second smooth part and the second ring part abut against each other.
[0008] Furthermore, the connector includes a connecting portion and connecting ends disposed at both ends of the connecting portion. The connecting portion is disposed within the left and right chessboards and spans the left and right chessboards. The lower surface of the connecting end is formed with an arc portion.
[0009] Furthermore, the electronic display component includes a circuit board and an LED array disposed on the circuit board. The chess pieces are inductively connected to the circuit board, and a display screen is also provided on the right chessboard.
[0010] Furthermore, both the left and right chessboards are equipped with several anti-slip rubber strips at the bottom, and a charging port and a power switch are located on the side.
[0011] The outstanding and beneficial technical effects of this utility model compared to the prior art are:
[0012] This invention relates to a foldable electronic chessboard that reduces its size when folded. The folded chessboard is compact and easy to carry. For chess enthusiasts, whether visiting friends' homes, participating in chess competitions, or enjoying a game while traveling, the foldable chessboard can be easily placed in a backpack or suitcase, eliminating the need to carry it constantly or use a larger bag. The folded design also provides integrated protection for the chess pieces, preventing loss due to separation. Furthermore, it facilitates easy relocation; for example, students playing in a classroom can simply fold it up to return to their dormitories for transport. The folded design also protects the chessboard surface. Moreover, this invention eliminates the need for hinges, avoiding… This invention avoids the creaking sound that can occur when hinges fold, prevents hand injuries from the edges of metal hinges, and eliminates the risk of rust from water contact. Instead, it incorporates a connector between the left and right chessboards. The left and right chessboards are connected to this connector, allowing for a smoother connection compared to direct contact which might create friction or resistance. The connector features a first and second rotating hole, each containing a first and second rotating shaft. The left and right chessboards can rotate around these shafts, allowing for independent folding and rotation. The rotating shafts provide a fixed center of rotation for the folding of the chessboards. This design allows the chessboard to fold along a predetermined path with precise positioning each time. The use of the first and second rotating axes ensures accurate alignment of all parts after folding, preventing damage to the chessboard's surface pattern or affecting its normal use due to inaccurate folding. The chessboard maintains stable positioning in both folded and unfolded states. When unfolded, the chessboard is firmly fixed on a flat surface, providing a smooth playing surface; when folded, it maintains a compact shape for easy storage and transport. The first and second rotating axes facilitate smoother folding. This reduces friction during folding, preventing difficulties or surface wear caused by excessive friction. The first and second rotating axes evenly distribute stress generated during folding and unfolding. When the chessboard is folded or unfolded, the material experiences tensile and compressive forces. The first and second rotating axes, acting as stress points, distribute these forces evenly across the entire chessboard structure, preventing excessive localized stress that could damage the material.

[0028] The present invention will be further described below with reference to specific embodiments:
[0029] A folding chessboard includes a left chessboard 1 and a right chessboard 2 that can be folded or unfolded relative to each other. Each chessboard 1 and right chessboard 2 has a pressable chess piece 12. An electronic display component is provided within each chessboard; pressing the chess piece 12 illuminates it. A connecting member 3 is provided between the left chessboard 1 and the right chessboard 2. The left chessboard 1 and the right chessboard 2 are rotatably connected to the connecting member 3 and can rotate around it. The connecting member 3 has a first rotating hole 4 and a second rotating hole 5, respectively. A first rotating shaft and a second rotating shaft are respectively provided within the first rotating hole 4 and the second rotating hole 5. The left chessboard 1 is rotatably connected to the connecting member 3 via the first rotating shaft and can rotate around it. The right chessboard 2 is rotatably connected to the connecting member 3 via the second rotating shaft and can rotate around it. At this point, the left chessboard 1 and the right chessboard 2 are folded and rotated.
[0030] This invention relates to a foldable electronic chessboard that reduces its size when folded. The folded chessboard is compact and easy to carry. For chess enthusiasts, whether attending a friend's party, participating in a chess competition, or enjoying a game while traveling, the foldable chessboard can be easily placed in a backpack or suitcase, eliminating the need to carry it constantly or use a larger bag. The folded chessboard also provides integrated protection for the chess pieces 12, preventing the pieces from being lost if stored separately. It also facilitates relocation; for example, students playing in a classroom can easily fold it to return to their dormitories. The folded chessboard also protects the chess surface. Furthermore, this invention eliminates the need for hinges, avoiding the problems associated with hinge folding. The folding mechanism avoids the creaking sound and prevents the iron hinges from scratching your hands. It also avoids the problem of hinges rusting easily when wet. This invention addresses this by using a connector 3 between the left chessboard 1 and the right chessboard 2. Both the left and right chessboards are connected to the connector 3, allowing for a smoother folding motion compared to direct contact which might cause friction or resistance. The connector 3 has a first rotating hole 4 and a second rotating hole 5, each containing a first rotating shaft and a second rotating shaft. The left and right chessboards can rotate around these shafts, allowing for independent folding and rotation. The rotating shafts provide a fixed center of rotation for the folding of the chessboards. This design allows the chessboard to fold along a predetermined path with precise positioning each time. The use of the first and second rotating axes ensures accurate alignment of all parts after folding, preventing damage to the chessboard's surface pattern or affecting its normal use due to inaccurate folding. The chessboard maintains stable positioning in both folded and unfolded states. When unfolded, the chessboard is firmly fixed on a flat surface, providing a smooth playing surface; when folded, it maintains a compact shape for easy storage and transport. The first and second rotating axes facilitate smoother folding. This reduces friction during folding, preventing difficulties or surface wear caused by excessive friction. The first and second rotating axes evenly distribute stress generated during folding and unfolding. When the chessboard is folded or unfolded, the material experiences tensile and compressive forces. The first and second rotating axes, acting as stress points, distribute these forces evenly across the entire chessboard structure, preventing excessive localized stress that could damage the material.
[0031] Preferably, the left chessboard 1 is provided with a first rotating tooth 6, and the right chessboard 2 is provided with a second rotating tooth 7. The first rotating tooth 6 and the second rotating tooth 7 are arranged adjacent to each other and mesh with each other. When the left chessboard 1 and the right chessboard 2 are driven to rotate relative to each other around the first rotating axis and the second rotating axis respectively, the first rotating tooth 6 and the second rotating tooth 7 can mesh with each other and rotate. By providing the first rotating tooth 6 and the second rotating tooth 7 on the left chessboard 1 and the right chessboard 2 respectively, when the left chessboard 1 and the right chessboard 2 rotate relative to the connecting member 3 around the first rotating axis and the second rotating axis respectively, the first rotating tooth 6 and the second rotating tooth 7 mesh with each other and rotate synchronously, so that the rotation process is smoother and more stable. The meshing of the first rotating tooth 6 and the second rotating tooth 7 can make the folding action of the chessboard more stable and smooth. Without rotating teeth, the folding of the chessboard may cause wear due to friction or collision between the two parts.
[0032] Preferably, the connector 3 is further provided with a first smooth part 8 and a second smooth part 9. The first smooth part 8 and the second smooth part 9 are respectively provided at both ends of the connector 3. The left chessboard 1 and the right chessboard 2 are respectively provided with a first ring part 10 and a second ring part 11. The first smooth part 8 and the first ring part 10 abut against each other, and the second smooth part 9 and the second ring part 11 abut against each other, so that the friction on the contact surface of the two is reduced when rotating, and the rotation is smoother, and the sound will not be too loud due to the friction between the objects.
[0033] Preferably, the connector 3 includes a connecting part 18 and connecting ends 19 disposed at both ends of the connecting part 18. The connecting part 18 is disposed within the left chessboard 1 and the right chessboard 2 and spans across the left chessboard 1 and the right chessboard 2. The lower surface of the connecting end 19 is formed with an arc portion 20.
[0034] Preferably, the electronic display component includes a circuit board 13 and an LED array disposed on the circuit board 13. The chess piece 12 is inductively connected to the circuit board 13. The right chessboard 2 is also provided with a display screen 14. The user presses the chess piece 12, and the LED array below the chess piece 12 displays different colors through the chess piece 12, thereby realizing the game between the two sides.
[0035] Preferably, the bottom of the left chessboard 1 and the right chessboard 2 are provided with several anti-slip rubber strips 15, and the sides are provided with charging ports 16 and start switches 17, which can prevent the left chessboard 1 and the right chessboard 2 from slipping when placed on a smooth ground or table. The charging ports 16 are used to charge the electronic display components, and the start switch 17 can be used to start the chessboard.
[0036] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
