Description

Technical Field

[0001] The present disclosure relates to the technical field of electronic Sudoku toys, and in particular to a Sudoku board digital display component and an electronic Sudoku machine. Background Art

[0002] At present, with the continuous improvement of parents' educational concepts, more and more parents pay more attention to their children's early intellectual development, and Sudoku, as a digital game with a long history, has always been loved by people. In recent years, as Sudoku games are favored by parents, smart Sudoku games based on Sudoku also have great market prospects. Traditional Sudoku games use paper to solve Sudoku problems. However, using paper not only wastes paper but also makes the problem-solving steps too cumbersome. This situation has led to the emergence of smart Sudoku machines. However, the assembly process of smart Sudoku machines on the market is complicated and cumbersome. The installation process of the central control circuit board and the Sudoku button assembly and the structure between the components are too complicated, which greatly increases the production cost.

[0003] For example, Chinese patent document CN116351042A discloses a switch-type intelligent Sudoku toy, in which the main surface of the chessboard is provided with a grid area, a problem-solving area, and multiple control buttons, a power supply is provided inside the chessboard, the grid area includes a plurality of first installation positions, and the problem-solving area includes a plurality of second installation positions; the display control component includes a plurality of first digital indicators with buttons provided on the sides and a plurality of digital buttons with trigger switches provided at the bottom; a control circuit board electrically connected to the power supply is provided inside the chessboard, and a plurality of touch switches are provided in an array above the control circuit board.

[0004] However, the design of the above-mentioned switch type intelligent Sudoku toy has the following problems:

[0005] Although the switch-type intelligent Sudoku toy is connected to the digital collection terminal of the Sudoku central control short-circuit board through a digital tube, the Sudoku toy has multiple Sudoku key components, and the Sudoku key components have multiple digital tubes. When the digital tubes are manually connected to the digital collection terminal of the central control circuit board, it is inevitable that the pins of the digital tubes will be disconnected or twisted during the assembly process. The disconnection or twisting of the pins of the digital tubes will easily weaken the conductive effect, resulting in a reduction in the display brightness of the Sudoku key area. At the same time, if Figure 1 As shown, during the manual installation process, the pins 310 of the digital tube 300 need to be inserted into the soldering holes of the central control circuit board 100 one by one, and the pins 310 of the digital tube 300 need to be accurately aligned with the soldering holes of the central control circuit board 100, which greatly increases the manufacturing complexity of the switch-type intelligent Sudoku toy and is prone to quality problems.

However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0034] like Figure 2 and Figure 3As shown, a Sudoku chessboard digital display component 10 of an embodiment includes a central control circuit board 100, a plurality of digital display light groups 1110 and a plurality of digital light-transmitting covers 200; a plurality of digital display areas 110 are provided on the central control circuit board 100, and each digital display light group 1110 is fixed in a corresponding digital display area 110; a buckle is provided on each digital light-transmitting cover 200, and a card slot is opened in each digital display area 110 of the central control circuit board 100; each digital light-transmitting cover 200 is covered on the corresponding digital display light group 1110, and each buckle is snapped into the corresponding card slot.

[0035] It can be understood that by setting the digital display area 110 on the central control circuit board 100 and fixing each digital display light group 1110 in the corresponding digital display area 110, the numbers to be displayed on the Sudoku board can be displayed through the lighting effect of the digital display light group 1110. Compared with the existing switch-type intelligent Sudoku toys, the above-mentioned Sudoku board digital display component 10, by directly setting the digital display light group 1110 on the central control circuit board 100, makes the digital display light group 1110 and the central control circuit board 100 more firmly connected, and there is no situation where the pin 310 of the digital tube 300 is disconnected or twisted during installation to weaken the conductivity, so that the digital display light group 1110 has a brighter display effect.

[0036] It can be understood that by making each digital light-transmitting cover 200 cover the corresponding display light group, the light-gathering property of the digital display in the Sudoku chessboard is enhanced, thereby improving the lighting effect of the digital display light group 1110. At the same time, compared with the existing Sudoku toy chessboard, by providing a buckle on the digital light-transmitting cover 200, a number of slots are opened in the digital display area 110 on the central control circuit board 100, and the buckle cooperates with the corresponding slots to make the digital light-transmitting cover 200 snap-connected to the central control circuit board 100, so that each digital light-transmitting cover 200 can be quickly installed on the corresponding digital display area 110 on the central control circuit board 100, ultimately increasing the efficiency of the installation of the Sudoku chessboard assembly and greatly reducing the complexity of the manufacturing process.

[0037] Combination Figure 3 As shown, specifically, the buckle is an L-shaped buckle 21a, and the slot is a rectangular slot 1140. It can be understood that by setting the buckle of the digital light-transmitting cover 200 as the L-shaped buckle 21a, and the slot of the central control circuit board is provided with a rectangular slot 1140, the digital light-transmitting cover 200 can be quickly snapped into the rectangular slot of the central control circuit board 100 by designing the L-shaped buckle 21a, and the rectangular slot 1140 can prevent the digital light-transmitting cover 200 from being offset during installation shaking when the L-shaped buckle 21a is snapped into the central control circuit board 100 through the rectangular shape.

[0038] Combination Figure 3 to Figure 4As shown, specifically, a positioning slot 1120 is provided in the digital display area 110, and a positioning post 220 is protruded toward the central control circuit board 100 on the digital light-transmitting cover 200, and the positioning post 220 is clamped in the positioning slot 1120. It can be understood that by providing the positioning slot 1120 in the digital display area 110 and the positioning post 220 on the digital light-transmitting cover 200, each positioning slot 1120 is correspondingly engaged with each positioning post 220, so that the digital light-transmitting cover 200 can be fixed to the central control circuit board 100.

[0039] Combination Figure 3 to Figure 4 As shown, further, the number of the positioning slots 1120 is at least two, and at least two positioning slots 1120 are arranged at intervals along the length direction of the digital display area 110. It can be understood that by arranging at least two positioning slots 1120 at intervals along the length direction of the digital display area 110, when the positioning posts 220 and the positioning slots 1120 are engaged one by one, the digital light-transmitting cover 200 can be securely fixed in the length direction of the digital display area 110, which can reduce the occurrence of lateral displacement of the digital light-transmitting cover 200 after installation. It can also be that at least two positioning slots 1120 are arranged at intervals along the diagonal direction of the digital display area 110. It can be understood that when the positioning posts 220 and the positioning slots 1120 are engaged one by one, the digital light-transmitting cover 200 can be securely fixed along the diagonal direction of the digital display area 110, which can reduce the occurrence of oblique displacement of the digital light-transmitting cover 200 after installation.

[0040] Combination Figure 3 and Figure 5 As shown, it may also be that the L-shaped buckle 210 includes a first L-shaped buckle 21a and a second L-shaped buckle 21b, and the first L-shaped buckle 21a and the second L-shaped buckle 21b are respectively arranged on opposite sides of the digital light-transmitting cover 200; the rectangular slot 1140 is divided into a first rectangular slot 114a and a second rectangular slot 114b, and the first rectangular slot 114a corresponds to the first L-shaped buckle 21a, and the second rectangular slot 114b corresponds to the second L-shaped buckle 21b. It can be understood that by setting the first rectangular slot 114a corresponding to the first L-shaped buckle 21a, when the first rectangular slot 114a is snap-fitted with the first L-shaped buckle 21a, one side of the digital light-transmitting cover 200 can be firmly fixed to the central control circuit board 100, and by setting the second rectangular slot 114b corresponding to the second L-shaped buckle 21b, when the second rectangular slot 114b is snap-fitted with the second L-shaped buckle 21b, the other side of the digital light-transmitting cover 200 can be firmly fixed to the central control circuit board 100, and finally the opposite sides of the digital light-transmitting cover 200 are more firmly fixed to the central control circuit board 100 and are less likely to fall off during use.

[0041] Combination Figure 3As shown, in one embodiment, the digital display lamp group 1110 includes a plurality of LED lamp beads 1111. The plurality of LED lamp beads 1111 are arranged at intervals within the digital display area 110, and the connection lines of the plurality of LED lamp beads 1111 are in the shape of the Chinese character 'Ri' (日). It can be understood that by arranging a plurality of LED lamp beads 1111 in the digital display area 110, since the connection lines of the plurality of LED lamp beads 1111 are in the shape of the Chinese character 'Ri', the user can adjust the number of lit LED lamp beads 1111 according to the number to be displayed, so as to display different numbers from 1 to 9 through the digital display lamp group 1110. For example, it can display shapes such as '丨', '6', or '7'. At the same time, combined with Figure 1 As shown, using LED lamp beads 1111 instead of the conventional digital tube 300 for display can avoid the disconnection or distortion of the pins 310 of the digital tube 300 during the assembly process, resulting in poor contact, and greatly improve the stability of digital display.

[0042] In one embodiment, at least one light-emitting indicator lamp 1130 is further provided within the digital display area 110, and at least one light-emitting indicator lamp 1130 is located within the digital display area 110. It can be understood that by arranging at least one light-emitting indicator lamp 1130 within the digital display area 110, the light-emitting indicator lamp 1130 can give a certain prompt to the user. For example, when the number displayed by the digital display lamp group 1110 in the digital display area 110 is a Sudoku problem, the light-emitting indicator lamp 1130 can remain constantly lit to prompt the user. It can also be, as Figure 3 As shown, the number of light-emitting indicator lamps 1130 is two, and the two light-emitting indicator lamps 1130 are arranged on the same diagonal of the digital display area 110. When the digital light-transmitting cover 200 is covered on the corresponding digital display lamp group 1110, the light of one of the light-emitting indicator lamps 1130 can pass through the digital light-transmitting cover 200 to prompt the user, while the other light-emitting indicator lamp 1130 can be used as a backup, so as to achieve a stable prompting effect.

[0043] Combined with Figure 3 As shown, in one embodiment, a light-emitting prompt through slot 240 is opened on the digital light-transmitting cover 200; the light-emitting prompt through slot 240 corresponds to the light-emitting indicator lamp 1130 one by one. It can be understood that by opening the light-emitting prompt through slot 240 on the digital light-transmitting cover 200, the light-emitting indicator lamp 1130 converges the light through the light-emitting prompt through slot 240 and emits it outward, making the light emitted by the light-emitting indicator lamp 1130 more obvious, which is conducive to quickly prompting the user.

[0044] Combined with Figure 3As shown, in this embodiment, the digital light-transmitting cover 200 is provided with a light-guiding slot 230 on the side away from the central control circuit board 100, and the digital display light group 1110 is arranged opposite to the light-guiding slot 230. It can be understood that by providing the light-guiding slot 230 on the digital light-transmitting cover, the digital display light group 1110 gathers the light through the light-guiding slot 230 and emits it outward, so that the light emitted by the digital display light group 1110 can be more clearly transmitted through the digital light-transmitting cover 200, which is more convenient for users to observe. Specifically, the light-guiding slot 230 is in the shape of a "sun", and the light-guiding slot 230 is closed by pouring light-transmitting glue, so that when the digital display light group 1110 displays numbers, it corresponds to the light-guiding slot 230, and the entire light-guiding slot 230 is evenly dispersed and illuminated under the conduction effect of the light-transmitting glue, so that the numbers displayed by the digital display light group 1110 are more obvious and clear. Among them, the light-transmitting glue can be epoxy resin glue, silicone resin or polyurethane, etc., which are not limited here.

[0045] Combination Figure 3 As shown, at least one light-controlled switch 120 is also provided on the central control circuit board 100; at least one light-controlled switch 120 is arranged outside the digital display area 110 and located on the diagonal line of the digital display area 110. It can be understood that by arranging the light-controlled switch 120 on the diagonal line of the digital display area 110, when the light-controlled switch 120 is pressed, the digital display light group 1110 in the digital display area 110 can be adjusted by the central control circuit board 100 to display different numbers. Alternatively, there are two light-controlled switches 120, and the two light-controlled switches 120 are arranged at intervals on the diagonal line of the digital display area 110. When the digital light-transmitting cover 200 is covered on the central control circuit board 100, the digital light-transmitting cover 200 is supported by the two light-controlled switches 120 and can be placed more flat. Meanwhile, when the user touches the corner of the digital light-transmitting cover 200 , since the light-controlled switches 120 are arranged on the diagonal line of the digital display area 110 , it can ensure that one light-controlled switch 120 is always pressed, thereby effectively increasing the probability of triggering the light-controlled switch 120 .

[0046] The present application also provides an electronic Sudoku machine device, including the Sudoku chessboard digital display assembly 10 described in any of the above embodiments. It can be understood that by using the Sudoku chessboard digital display assembly 10 disclosed in the present invention in the electronic Sudoku machine, not only the digital light-transmitting cover 200 and the central control circuit board 100 are more firmly and conveniently fixed, but also the digital tube 300 and the key are prevented from being disconnected or twisted during installation.

[0047] Compared with the prior art, the present invention has at least the following advantages:

[0048] 1) By setting a digital display area 110 on the central control circuit board 100, and fixing each digital display light group 1110 in the corresponding digital display area 110, the numbers to be displayed on the Sudoku board can be displayed through the lighting effect of the digital display light group 1110. Compared with the existing switch-type intelligent Sudoku toys, the above-mentioned Sudoku board digital display component 10, by directly setting the digital display light group 1110 on the central control circuit board 100, makes the digital display light group 1110 and the central control circuit board 100 more firmly connected, and there is no situation where the pin 310 of the digital tube 300 is disconnected or twisted during installation to weaken the conductivity, so that the digital display light group 1110 has a brighter display effect.

[0049] 2) By making each digital light-transmitting cover 200 cover the corresponding display light group, the light-gathering property of the digital display in the Sudoku chessboard is enhanced, thereby improving the lighting effect of the digital display light group 1110. At the same time, compared with the existing Sudoku toy chessboard, by providing a buckle on the digital light-transmitting cover 200, a number of slots are provided in the digital display area 110 on the central control circuit board 100, and the buckle cooperates with the corresponding slots to make the digital light-transmitting cover 200 snap-fitted to the central control circuit board 100, so that each digital light-transmitting cover 200 can be quickly installed on the corresponding digital display area 110 on the central control circuit board 100, ultimately increasing the efficiency of the installation of the Sudoku chessboard assembly and greatly reducing the complexity of the manufacturing process.

[0050] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
