Description

Technical Field

[0001] This utility model relates to the field of game consoles, and more specifically, to a multifunctional electronic chessboard. Background Technology

[0002] The operation buttons on existing electronic chessboards are typically integrated into the board structure, commonly located in the area directly below the display screen. This design is primarily based on considerations of functional expansion. By placing more physical buttons (such as undo, resignation, and timer control buttons) in a high-density area, more refined functions can be achieved, meeting the demands of professional chess games for precision and versatility. However, this design has significant limitations. In miniaturized electronic chessboards, the space below the display screen is drastically reduced, forcing smaller buttons and narrower spacing. This not only significantly reduces the tactile feedback, leading to increased accidental touches and unclear button responsiveness, but also causes the button layout to encroach on the screen display area, resulting in visual obstruction, such as affecting the recognition of move placements or the display of the game status, severely weakening the user experience. Furthermore, miniaturized chessboards often employ compact structural designs to achieve portability, further limiting the flexibility of button layout and exacerbating the space conflict between the operation area and the display area.

[0003] To address the aforementioned issues, existing technologies have not yet offered effective solutions. Optimizing the operational layout within a limited chessboard size, balancing functionality and user comfort, while avoiding interference with screen display, has become a critical technological bottleneck that urgently needs to be overcome. This is especially true in the portable electronic chessboard sector, where users increasingly demand ease of operation and immersive gameplay; existing solutions can no longer meet the market's expectations for high-performance, miniaturized products. Utility Model Content

[0004] The present invention aims to overcome at least one of the defects of the prior art and provide a multifunctional electronic chessboard to solve the problem that the limited size of the existing chessboard due to the operation buttons results in poor operability and gaming experience.

[0005] The technical solution adopted in this utility model is a multifunctional electronic chessboard, comprising: A multifunctional electronic chessboard includes: a chessboard body and a control component disposed on the chessboard body; The chessboard body includes: a display surface, on which multiple display units are arranged in an array; The display unit has at least two active states; The control component includes: at least two first adjustment mechanisms, independent of the main body of the chessboard, for switching the currently selected display unit from one display unit to another, and at least one second adjustment mechanism for adjusting the current state of the currently selected display unit.

[0006] The display surface is used to show game content and operation instructions; the first adjustment structure is located outside the main body of the chessboard for easy adjustment.

[0007] To allow for quick game switching, the first adjustment mechanism is rotatably connected to the main body of the chessboard. The rotation axis of the first adjustment mechanism is perpendicular to the side of the chessboard body.

[0008] Rotating the first adjustment mechanism switches between games; different angles correspond to different games.

[0009] By replacing buttons with a rotating mechanism, operators can easily switch between and return to the game at any time, improving the portability of the operation.

[0010] To improve game operation efficiency, the display surface is a horizontal plane; The display units are distributed in a matrix array on a horizontal plane; The first adjustment mechanism is used to switch the currently displayed unit from one display unit to another display unit adjacent to it; The switching directions of each primary regulating mechanism are different.

[0011] The different switching directions of the first adjustment mechanism correspond to certain functions, and the operator can rotate the first adjustment mechanism to operate quickly.

[0012] To facilitate gripping the chessboard, the display surface is located on the top surface of the main body of the chessboard; The main body of the chessboard includes two first adjustment mechanisms and one second adjustment mechanism; The first adjustment mechanism is respectively disposed on both sides of the chessboard body and is movably connected to the side of the chessboard body; The second adjustment mechanism is located between the two first adjustment mechanisms and is connected to the side of the chessboard body.

[0013] The two first adjustment mechanisms and the second adjustment mechanism operate in a triangular position outside the chessboard, which can improve control speed and stabilize the grip on the chessboard.

[0014] To obtain feedback and facilitate use, the chessboard body includes: a hollow shell, and a screen, a dimming component, and a control circuit board arranged sequentially within the shell; The housing includes: an upper cover and a lower cover with an opening on the top surface; the screen is close to the upper cover and closes the opening; A power supply component and a feedback component are also provided between the control circuit board and the lower cover; The control circuit board is connected to the power supply component, the feedback component, and the control component, respectively. The control circuit board is equipped with an array of light sources, which are transmitted through the dimming component to form display units on the screen.

[0015] The open top cover makes it easy to observe the screen. The power supply component is the battery compartment, which powers the electronic chessboard. The feedback component is the speaker, which provides sound feedback to the operator. The dimming component is used to adjust the intensity and size of the display unit.

[0016] To optimize the display unit's performance, the dimming assembly includes a diffuser film, a light-shielding component, and a light guide component that are matched with the light source and arranged in sequence. The diffuser film is located near the screen.

[0017] Light guides are used to extend the transmission distance of light, light shields are used to shape the light source, and diffusers are used to eliminate sharpness.

[0018] To reduce interference between light rays and protect the light source, the light guide includes: a connecting piece and a light guide array disposed on the connecting piece; The light guide array includes: multiple light guide pillars arranged in multiple rows and columns; The light guide column has a compartment for accommodating the light source and an opening is formed on the side near the control circuit board; The distance between two adjacent light guides in the same row is equal, and / or the distance between two adjacent light guides in the same column is equal.

[0019] Light guides are used to separate light from other light sources, concentrate light from the corresponding light source, and protect the light source. Connecting pieces enhance the structural strength of the light guide.

[0020] In order to extend the propagation distance of light, the connecting piece is connected to the middle of the light guide post; This is such that each light guide post forms a mutually separated forward convex structure on the face side of the connecting piece and a mutually separated rear convex mechanism on the back side of the connecting piece. The receiving openings of each light guide column are located in the same horizontal plane.

[0021] The forward and backward convex mechanisms are used to converge light rays and extend the propagation length of light.

[0022] To enhance the fixing effect, the light-shielding component includes: The mounting plate is provided with multiple mounting holes, the number and position of which match the light guide post; Multiple installation pipes, one end of which is connected to the back side of the installation plate and communicates with the installation hole; The edging is connected at one end to the edge of the mounting plate, and the length of the edging is not less than the length of the mounting channel.

[0023] The installation pipe is used to fix the light guide column.

[0024] To save space, the light-diffusing film includes: a light guide body and a light-shielding sheet disposed on the light-emitting surface of the light guide body; The light-emitting surface of the light guide body includes: a chessboard area in the middle and a blank area surrounding the chessboard area; The chessboard area is provided with dividing strips for forming chess squares; The light-blocking sheet closes the empty area and the dividing strip.

[0025] The light guide body is used to let light pass through, the light shield is used to block light, and the dividing strips are laid in the chessboard area to form a chess grid.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting the first adjustment mechanism and the second adjustment mechanism outside the chessboard, the space occupied on the front of the chessboard is reduced, so that the main operations are concentrated outside the chessboard, and the screen can display more information or more clearly, improving the operator's viewing experience; different functions are assigned to the first adjustment mechanism and the second adjustment mechanism, making it easier for the operator to distinguish and use them.

[0027] Furthermore, by setting the first adjustment mechanism on the left and right sides of the chessboard body and assigning different functions to the position and rotation angle of the first adjustment mechanism, different first adjustment mechanisms represent different sets of functions. At the same time, the functions of the second adjustment mechanism are also different from those of the first adjustment mechanism. This refines the functional modules, making it easier for the operator to operate and distinguish them quickly, and improving the operator's operating efficiency. Attached Figure Description

[0043] Explanation of reference numerals in the attached figures: Chessboard body 100: Display surface 110: Display unit 111; Housing 120: Top cover 121, bottom cover 122; Screen 130; Dimming assembly 140: Diffusing film 141: Light guide body 1411: Chessboard area 1412, empty area 1413; Light shield 1414, partition strip 1415; Light shield 142: Mounting plate 1421, mounting hole 1422, mounting channel 1423, surrounding edge 1424; Light guide 143: Light guide column 1431, receiving port 1432, connecting piece 1433; Control circuit board 150: Light source 151; Power supply assembly 160, feedback assembly 170. Control components 200: First adjustment mechanism 210, second adjustment mechanism 220. Detailed Implementation

[0044] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product; it is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0045] Example 1 like Figure 1-3 As shown, this embodiment is a multifunctional electronic chessboard, including: a chessboard body 100, and a control component 200 disposed on the chessboard body 100; The chessboard body 100 includes: a display surface 110, on which a plurality of display units 111 are arranged in an array; The display unit 111 has at least two activation states; The control component 200 includes: at least two first adjustment mechanisms 210, which are independent of the chessboard body 100, for switching the currently selected display unit 111 from one display unit 111 to another display unit 111, and at least one second adjustment mechanism 220 for adjusting the current state of the currently selected display unit 111.

[0046] The display surface 110 expresses game and operation information through the display unit 111, using various combinations of the display unit 111 and changes in brightness to convey rich information. The display unit 111 has two activation states: lighting up two colors, either red and blue or red and green, with a clear color difference, representing the operator and the human-computer interface (computer opponent) on the electronic chessboard, respectively. If red represents the operator and blue represents the human-computer interface, when red is lit, it indicates that it is the operator's turn to act, and when blue is lit, it indicates that it is the human-computer interface's turn to act. The first adjustment mechanism 210 is placed outside the chessboard, reducing the space occupied on the front of the chessboard and allowing the screen 130 to display more information or a larger area, improving the operator's viewing experience. The first adjustment mechanism 210 and the second adjustment mechanism 220 are assigned different functions to facilitate the operator's differentiation and use. With the independent first adjustment mechanism 210 and the second adjustment mechanism 220, the main operations are concentrated outside the chessboard, making operation more convenient and improving the game's viewing experience without affecting the display on the screen 130.

[0047] like Figure 1-2 As shown, the first adjustment mechanism 210 is rotatably connected to the chessboard body 100; The rotation axis of the first adjustment mechanism 210 is perpendicular to the side of the chessboard body 100.

[0048] Traditional button-based game switching typically involves pressing once to jump to the next game. If the operator accidentally presses the wrong button, they will be redirected to the next game and need to press the button again until the desired game appears. When there are many games on the console, the button method reduces the efficiency of game switching and the operator's gaming experience. Compared to traditional buttons, the first adjustment mechanism 210 uses a rotation method to switch games. Rotating to a certain angle switches to the next game. If the operator rotates too far or too little, they can adjust at any time, allowing for quick switching and improving operational efficiency, portability, and gaming experience.

[0049] like Figure 1-3 As shown, the display surface 110 is a horizontal plane; The display units 111 are arranged in a matrix array on a horizontal plane; The first adjustment mechanism 210 is used to switch the current display unit 111 from one display unit to another adjacent display unit 111; The switching directions of each of the first regulating mechanisms 210 are different.

[0050] Each direction of the first adjustment mechanism 210 corresponds to a different function, and different first adjustment mechanisms 210 also represent different sets of functions. When the operator needs to change the game operation, he can rotate the corresponding first adjustment mechanism 210 and rotate the corresponding angle to achieve this. By refining the function through the position and rotation angle of the first adjustment mechanism 210, the operation becomes faster and more effective.

[0051] like Figure 1-2 As shown, the display surface 110 is disposed on the top surface of the chessboard body 100; The chessboard body 100 includes two first adjustment mechanisms 210 and one second adjustment mechanism 220; The first adjustment mechanism 210 is respectively disposed on both sides of the chessboard body 100 and is movably connected to the side of the chessboard body 100; The second adjustment mechanism 220 is located between the two first adjustment mechanisms 210 and is connected to the side of the chessboard body 100.

[0052] The first adjustment mechanism 210 is located on the left and right sides of the chessboard body 100, and both can rotate. The second adjustment mechanism 220 is usually located on the chessboard near the operator. The second adjustment mechanism 220 and the first adjustment mechanism 210 are in a triangular position outside the chessboard. When the operator is playing the game, the first adjustment mechanism 210 can help the operator to grip and stabilize the chessboard. Furthermore, the second adjustment mechanism 220 is located near the operator, so the distance from the operator's hand to the second adjustment mechanism 220 is short, allowing for quick operation.

[0053] like Figure 1-15 As shown, the chessboard body 100 includes: a hollow shell 120, and a screen 130, a dimming assembly 140, and a control circuit board 150 arranged sequentially within the shell 120. The housing 120 includes: an upper cover 121 and a lower cover 122 with an opening on the top surface; the screen 130 is close to the upper cover 121 and closes the opening; A power supply component 160 and a feedback component 170 are also provided between the control circuit board 150 and the lower cover 122; The control circuit board 150 is connected to the power supply component 160, the feedback component 170 and the control component 200 respectively; The control circuit board 150 is provided with an array of light sources 151, and the light sources 151 form a display unit 111 on the screen 130 through the dimming component 140.

[0054] The screen 130 is installed between the upper cover 121 and the lower cover 122. The upper cover 121 has an opening, and there is a certain distance between the screen 130 and the highest point of the upper cover 121. When the chessboard is dropped, it can prevent the screen 130 from directly contacting the ground and can also provide some cushioning to protect the screen 130. The power supply component 160 is a battery compartment that powers the electronic chessboard, allowing the operator to use it anytime and anywhere. The feedback component 170 is a speaker that provides different feedback to the operator through various sound effects, enhancing the operator's gaming experience. The dimming component 140 can adjust the intensity and size of the display unit 111 on the screen 130 by means of blocking light, extending the light path, etc., to display different information and enrich the expression of information.

[0055] like Figure 7 and 15 As shown, the dimming assembly 140 includes a diffuser 141, a light shield 142, and a light guide 143 that are matched with the light source 151 and arranged in sequence. The diffuser film 141 is located near the screen 130.

[0056] The light source 151 extends the light transmission distance through the light guide 143, and also gathers the light and enhances the light intensity. Through the light shield 142, it is shaped into different shapes to express different information. However, the light distribution is uneven at this time, and the resulting pattern is also uneven in brightness. Long-term viewing will cause eye strain. Therefore, an additional diffuser film 141 is added to eliminate sharpness, make the light distribution uniform, and ensure consistent pattern brightness. Through a simple combination, a high-quality display unit 111 effect can be obtained, and the burden on the eyes can also be reduced.

[0057] like Figure 13-15 As shown, the light guide 143 includes: a connecting piece 1433 and a light guide array disposed on the connecting piece 1433; The light guide array includes: multiple light guide pillars 1431 arranged in multiple rows and columns; The light guide post 1431 has a compartment for accommodating the light source 151 and a receiving opening 1432 is formed on the side near the control circuit board 150. The distance between two adjacent light guide pillars 1431 in the same row is equal, and / or the distance between two adjacent light guide pillars 1431 in the same column is equal.

[0058] The light guide post 1431 has a certain length. The light emitted by the light source 151 is collected in the light guide post 1431 through the receiving port 1432. Each light source 151 corresponds to one light guide post 1431, which can concentrate the light and increase the light intensity; and isolate the light from other light sources 151, reducing interference from other light sources 151; and each light source 151 is framed by the light guide post 1431, which is equivalent to each light source 151 having a protective shield around its outer ring. When the chessboard is impacted, the light guide post 1431 protects each light source 151 and acts as a buffer. The light guide array is connected by the connecting piece 1433 to enhance the structural strength of the light guide component 143.

[0059] like Figure 13-15 As shown, the connecting piece 1433 is connected to the middle part of the light guide post 1431; This is such that each light guide post 1431 forms a mutually separated forward convex structure on the face side of the connecting piece 1433 and a mutually separated rear convex mechanism on the back side of the connecting piece. The receiving opening 1432 of each light guide post 1431 is located in the same horizontal plane. By fixing the light guide post 1431 to the connecting piece 1433, the light guide post 1431 is fixed, ensuring that the light guide components 143 do not shift; and the receiving opening 1432 located on the same horizontal plane can cooperate well with the control circuit board 150 to cover the light source 151 and improve the purity of the light source.

[0060] like Figure 11-13 As shown, the light-shielding member 142 includes: The mounting plate 1421 is provided with a plurality of mounting holes 1422, the number and position of which match the light guide post 1431; Multiple installation pipes 1423 are connected at one end to the back side of the installation plate 1421 and communicate with the installation hole 1422; The edging 1424 is connected at one end to the edge of the mounting plate 1421, and the length of the edging 1424 is not less than the length of the mounting channel 1423.

[0061] The edging 1424 and the mounting pipe 1423 are together formed at the matching mounting position of the light guide 143. When the light guide post 1431 of the light guide 143 and the mounting channel 1423 of the light shield 142 are matched one by one, the light passes through the mounting hole 1422 through the light guide post 1431. The light outside the light guide post 1431 is blocked outside the mounting channel 1423, making the light cleaner. In addition, when the light guide post 1431 is embedded in the mounting channel 1423, the light shield 142 can protect the light guide 143.

[0062] like Figure 1-4As shown in Figures 8-10, the light-diffusing film 141 includes: a light guide body 1411, and a light-shielding sheet 1414 disposed on the light-emitting surface of the light guide body 1411; The light-emitting surface of the light guide body 1411 includes: a chessboard area 1412 located in the middle and a blanking area 1413 surrounding the chessboard area 1412; The chessboard area 1412 is provided with dividing strips 1415 for forming chess squares; The light-blocking sheet 1414 encloses the empty area 1413 and the dividing strip 1415.

[0063] The light guide body 1411 is a circular light-transmitting sheet, which can soften the light transmitted from the light shield 142 and reduce sharpness. Since the light guide 143 and the light shield 1414 are circular in shape, in order to display the chessboard on the screen 130, the light guide body 1411 is divided into a chessboard area 1412 and an empty area 1413. The light shield 1414 is attached to the empty area 1413 so that only the chessboard area 1412 is displayed on the screen 130. The dividing strip 1415 is laid on the chessboard area 1412, and the light shield 1414 is attached to the dividing strip. 414, forming individual chess squares, with each intersection of the dividing strips 1415 corresponding to each display unit 111, so that the display unit 111 can be presented on the screen 130 as chess pieces on the chessboard; forming the chessboard on the diffuser film 141 is clearer than displaying it through the light source 151, because the diffuser film 141 is closest to the screen 130 and can form a clear chessboard, and this design is simple, can reduce the number and arrangement complexity of the light sources 151, save space for the electronic chessboard, and can also achieve better results.

[0064] Example 2 A multifunctional electronic chessboard, as described in Embodiment 1, consists of a chessboard body 100 and a control component 200. The top of the chessboard body 100 is provided with a display surface 110 and multiple display units 111 arranged in an array on the display surface. The display units 111 express rich game information through various arrangements and combinations.

[0065] The main body 100 of the chessboard includes a hollow shell 120, and a screen 130, a dimming component 140, a control circuit board 150, a power supply component 160, and a feedback component 170 arranged sequentially inside the shell 120. The shell 120 consists of an upper cover 121 with an opening on the top surface and a lower cover 122. The power supply component 160 and the feedback component 170 are located between the lower cover and the control circuit board 150. The power supply component 160 is a battery compartment that supplies power to the control circuit board 150, making it convenient for the operator to enjoy entertainment anytime and anywhere. The feedback component 170 is a speaker that is connected to the control circuit board 150 to provide feedback through sound effects, thereby enhancing the gaming experience.

[0066] The screen 130 is positioned near the top cover 121, closing the opening of the top cover 121. Between the screen 130 and the control circuit board 150 is a dimming assembly 140, consisting of a diffuser film 141, a light shield 142, and a light guide 143. The diffuser film 141 is positioned near the screen 130, and the light guide 143 is positioned near the control circuit board 150. The control circuit board 150 has an array of light sources that emit light, which passes through the dimming assembly 140 to form display units 111 on the screen 130. The dimming assembly 140 also separates the light sources from the screen 130, protecting the light sources.

[0067] The light guide 143 extends the light path and concentrates the light from the corresponding light source, while blocking the light from other light sources, making the light purer and brighter. The light passing through the light guide pillar passes through the light shield 142 and hits the diffuser film 141. The light outside the light guide pillar is blocked outside the light shield 142, further reducing interference. Before passing through the diffuser film 141, the light has uneven brightness and excessive edge light. The diffuser film 141 softens the light, reduces sharpness, and reduces the eye strain on the operator. Furthermore, the light shield and dividing strips set on the diffuser film 141 allow the light passing through the diffuser film 141 to hit the screen 130 and form a chessboard. This design does not require additional light sources to form the chessboard, reducing the complexity of the design. It also eliminates the need for an additional chessboard. The diffuser film 141 achieves the functions of reducing sharpness and forming a chessboard, saving the structural space and manufacturing cost of the electronic chessboard.

[0068] The control component 200 includes two first adjustment mechanisms 210 and a second adjustment mechanism 220. The first adjustment mechanisms 210 are located on the left and right sides of the chessboard body 100, while the second adjustment mechanism 220 is typically located on the chessboard body 100 closer to the operator. The first adjustment mechanisms 210 and 220 together form a triangle. When the operator is playing, the first adjustment mechanism 210 assists the operator in gripping and stabilizing the chessboard. Because the second adjustment mechanism 220 is located close to the operator, the path for the operator's hand to reach the second adjustment mechanism 220 is shorter, facilitating quick operation. The first adjustment mechanism 210 is used to switch the current display unit 111 to another display unit 111, while the second adjustment mechanism 220 adjusts the state of the current display unit 111. The first adjustment mechanisms 210 on the left and right sides represent different sets of functions. By rotating the angle of the first adjustment mechanism 210, the functions are switched. This design refines the functions of the first adjustment mechanism 210, enabling the operator to perform quick and effective operations.
