Description

Technical Field

[0001] This utility model demonstrates a disassembly warning device for the dice plate assembly of a mahjong machine, the dice plate assembly, and the mahjong machine, belonging to the technical field of mahjong machine. Background Technology

[0002] When automatic mahjong machines are in use, some people may attempt to cheat for personal gain or other ulterior motives. A typical example is disassembling the mahjong machine and replacing the motherboard or dice plate software and hardware to control the shuffling, card dealing, and dice rolls. Such disassembly and alteration are difficult to detect, thus affecting the overall operation of the card room and easily leading to a poor gaming experience. Utility Model Content

[0003] The purpose of this invention is to solve the problem that it is difficult to detect when the software or hardware of the dice disk assembly is disassembled or modified. To this end, a disassembly warning device for the dice disk assembly of a mahjong machine, the dice disk assembly, and the mahjong machine are provided. By acquiring timing information, the power supply circuit of the timing circuit is accurately detected to be de-energized, thereby detecting that the dice disk assembly has been disassembled.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A disassembly warning device for the dice plate assembly of a mahjong machine includes: A switching element, mounted on the dice disk assembly, that can send a signal in response to the disassembly of a detachable part on the dice disk assembly; A timing module and a timing power supply circuit, wherein the timing power supply circuit responds to the signal of a switching element to trigger on / off switching, and the timing power supply circuit has an output terminal and a first input terminal, the output terminal being connected to the timing module, and the first input terminal being used to connect to an external power supply; The control module, which is electrically connected to the timing module, is configured to perform disassembly detection based on the timing information from the timing module.

[0005] The beneficial effects of using this utility model are: The disassembly warning device described in this utility model includes a timing module, a timing power supply circuit, and a control module. Under normal operating conditions, the timing power supply circuit remains normally conductive, the switching element does not emit a signal, the timing module generates timing information in real time, and the control module reads and records the timing information. When a detachable part of the dice assembly is disassembled, the switching element responds and emits a signal. The timing power supply circuit responds to the signal from the switching element and triggers a power outage. The timing module stops generating timing information. At this time, the control module cannot read the timing information from the timing module and will send an alarm signal to the manufacturer or manager, so that the manufacturer or manager can immediately receive information that the dice assembly has been disassembled, thereby enabling... The system allows for timely monitoring of the control module to prevent tampering with its control program, ensuring fairness and a positive gaming experience. Furthermore, the control module periodically reads the timing information from the timing module, enabling precise data on when the timing power supply circuit was disconnected. This provides manufacturers and administrators with accurate timing data, allowing them to understand the exact time the dice board assembly was disassembled. The timing information is hardware-generated and cannot be modified by software, ensuring its authenticity. Finally, the integration of the timing module with the switching element enables dual monitoring of both physical switches and electronic data recording, allowing the control module to effectively and accurately detect the disassembly of the dice board assembly.

[0006] Preferably, the timing power supply circuit also has a second input terminal, which is connected to an internal energy storage element. This internal energy storage element maintains power supply during external power outages. Using the aforementioned technical solution, when the external power supply is disconnected, the energy storage element discharges to supply power to the timing module, ensuring the control module can read the timing information. This prevents the timing power supply circuit from being de-energized due to power outages or the disconnection of the external power supply, reducing the possibility of erroneous detection by the control module and making the control module's disassembly and detection of the dice disk assembly more accurate and reliable.

[0007] Preferably, the first input terminal and the second input terminal are connected in parallel in the timing power supply circuit. When the first input terminal is connected to an external power source, the external power source simultaneously supplies power to the energy storage element, enabling the energy storage element to store electrical energy. Using the aforementioned technical solution, when the dice disk assembly is in normal use, the external power source supplies power to the timing module while simultaneously charging the energy storage element, ensuring that the energy storage element always remains charged. This allows the energy storage element to continuously provide power to the timing power supply circuit after the external power source is disconnected.

[0008] Preferably, the switching element is connected in series in the timing power supply circuit, acting as a switch to control its on / off state.

[0009] Preferably, the control module is equipped with a power supply module, and the control module is electrically connected to an alarm module. The alarm module is configured to issue an alarm signal when the timing power supply circuit is disconnected. Using the aforementioned technical solution, the power supply module can independently power the control module. When the timing power supply circuit is de-energized, the control module can still maintain normal operation under the power supply of the power supply module, thereby enabling it to issue an alarm signal through the alarm module based on detection information, and thus promptly alerting the manufacturer or administrator to the power outage of the timing power supply circuit.

[0010] Preferably, the dice board assembly includes a tray, a cover, and a control main board. The tray and the cover can be closed together to form a mounting cavity for installing the control main board. The control main board is part of the control module. The tray, the cover, and the control main board are all detachable components.

[0011] Preferably, the switching element includes a micro switch, which is mounted on the control main board. The switch button of the micro switch abuts against the tray or cover to keep the timing power supply circuit connected.

[0012] Preferably, the switching element includes a Hall switch, which is mounted on the control main board. A magnet is mounted on the tray or cover plate, and the Hall switch is moved away from the magnet to control the timing power supply circuit to disconnect.

[0013] This utility model also demonstrates a dice pan assembly, including a tray and a cover plate, with the cover plate covering the top of the tray. The dice pan assembly is also provided with a disassembly warning device as described in any of the above.

[0014] This utility model also demonstrates a mahjong machine, including a table body, with a table board and a dice plate assembly at the top of the table body. The dice plate assembly is connected to the table body via a lifting assembly, and the dice plate assembly is equipped with a disassembly warning device for the mahjong machine dice plate assembly as described in any of the above-mentioned embodiments.

[0015] Other features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

However, the following embodiments are only preferred embodiments of the present utility model and not all of them.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Example 1: like Figures 1 to 4 As shown in the figure, this embodiment illustrates a disassembly warning device for the mahjong machine dice plate assembly, including: Switching element 4 is mounted on the dice disk assembly and can send a signal in response to the disassembly action of the detachable parts on the dice disk assembly; The timing module 5 and the timing power supply circuit are provided. The timing power supply circuit is triggered to switch on and off in response to the signal of the switching element 4. The timing power supply circuit has an output terminal and a first input terminal. The output terminal is connected to the timing module 5 and the first input terminal is used to connect to the external power supply 61. The control module is electrically connected to the timing module 5 and is configured to perform disassembly detection based on the timing information from the timing module 5.

[0022] In this embodiment, the disassembly warning device includes a timing module 5, a timing power supply circuit, and a control module. When the dice disk assembly is operating normally, the timing power supply circuit remains normally conductive, the switching element 4 does not emit a signal, the timing module 5 generates timing information in real time, and the control module reads and records the timing information. When a detachable part of the dice disk assembly is disassembled, the switching element 4 responds and emits a signal. The timing power supply circuit responds to the signal from the switching element 4 and triggers a power outage. The timing module 5 stops generating timing information. At this time, the control module cannot read the timing information from the timing module 5 and will send an alarm signal to the manufacturer or manager so that the manufacturer or manager can immediately receive information that the dice disk assembly has been disassembled. The system can promptly detect the control module to prevent tampering with its control program, ensuring fairness and a positive gaming experience. Furthermore, the control module periodically reads the timing information from the timing module 5, enabling it to accurately determine the time the timing power supply circuit was disconnected. This provides manufacturers or administrators with precise timing data, allowing them to understand the exact time the dice board assembly was disassembled. Since the timing information from the timing module 5 is hardware-generated and cannot be modified by software, its authenticity is guaranteed. Secondly, the integration of the timing module 5 with the switching element 4 enables dual monitoring of both physical switching and electronic data recording, allowing the control module to effectively and accurately detect the disassembly of the dice board assembly.

[0023] like Figure 2 and Figure 3 As shown, the dice board assembly in this embodiment includes a tray 2, a cover plate 1, and a control main board 3. The tray 2 has a bowl-shaped structure, and the cover plate 1 covers the top of the tray 2, forming an installation cavity between the tray 2 and the cover plate 1. The control main board 3 and the switching element 4 are both fixed in the installation cavity. The control main board 3 is part of the control module, and the tray 2, cover plate 1, and control main board 3 are all detachable parts of the dice board assembly. Specifically, in this embodiment, the control main board 3 is fixedly connected to the tray 2, and the switching element 4 is fixed to the lower end face of the control main board 3. The switching element 4 includes a micro switch with a switch button 41. The switching element 4 is connected in series with the timing supply... In the electrical circuit, the switch, which acts as the timing power supply circuit, controls its on / off state. After the control main board 3 is fixed on the tray 2, the switch button 41 of the micro switch abuts against the tray 2, keeping the micro switch in the open state so that the timing power supply circuit remains conductive. The timing module 5 can generate timing information normally, and the control module reads the timing information in real time. However, when the control main board 3 is separated from the tray 2, the switch button 41 is no longer under force, and the micro switch automatically disconnects. The timing power supply circuit is disconnected and no longer supplies power to the timing module 5. The timing module 5 stops generating timing information, and the control module cannot obtain timing information. At this time, the control module generates an alarm signal to indicate to the manufacturer or manager that the dice disk assembly has been disassembled.

[0024] It is understandable that in other embodiments, the switch element 4 may also be fixed to the upper surface of the control motherboard 3, with the switch button 41 of the micro switch abutting against the cover plate 1 to keep the micro switch in the open state; when the control motherboard 3 is separated from the cover plate 1, the switch button 41 is not under force, the micro switch is automatically disconnected, the timing power supply circuit is disconnected and no longer supplies power to the timing module 5, the timing module 5 stops generating timing information, and the control module cannot obtain timing information. At this time, the control module generates an alarm signal to remind the manufacturer or manager that the dice board assembly has been disassembled.

[0025] In this embodiment, the inner side of the tray 2 is provided with an upwardly protruding reinforcing rib 21. The switch button 41 of the micro switch abuts against the reinforcing rib 21. The reinforcing rib 21 can enhance the strength of the tray 2 or the cover plate 1, and can also serve as a trigger for the micro switch, thus eliminating the need for additional triggers and reducing the number of components to be assembled.

[0026] It is understandable that in other embodiments, when the switch button 41 of the micro switch abuts against the cover plate 1, the lower surface of the cover plate 1 may also be provided with reinforcing ribs 21, and the switch button 41 of the micro switch abuts against the reinforcing ribs 21 of the cover plate 1.

[0027] It is understandable that in other embodiments, the switch element 4 may also be fixed on the tray 2, with the switch button 41 of the switch element 4 abutting against the control main board 3 to keep the switch element 4 conducting; or, in other embodiments, the switch element 4 may also be fixed on the lower surface of the cover plate 1, with the switch button 41 of the switch element 4 abutting against the control main board 3 to keep the switch element 4 conducting.

[0028] It is understandable that in other embodiments, the switching element 4 can also be a Hall switch. A magnet is installed on the tray 2. When the control motherboard 3 is installed in the tray 2, the magnet is close to the Hall switch to keep the Hall switch conducting. When the control motherboard 3 is removed from the tray 2, the Hall switch moves away from the magnet on the tray 2, and the Hall switch automatically disconnects due to the change in the induced magnetic field.

[0029] It is understandable that in other embodiments, the switching element 4 may also be mounted on the upper surface of the control motherboard 3, and a magnet may also be mounted on the cover plate 1.

[0030] like Figure 4As shown, the timing power supply circuit in this embodiment has a first input terminal and a second input terminal. The first input terminal is used to connect to an external power supply 61, and the second input terminal is connected to an energy storage element 62. The external power supply 61 and the energy storage element 62 are connected in parallel in the timing power supply circuit. The timing module 5 and the switching element 4 are connected in series in the timing power supply circuit. When the first input terminal is connected to the external power supply 61, the external power supply 61 supplies power to the timing module 5 and also supplies power to the energy storage element 62. At this time, the external power supply 61 can charge the energy storage element 62. During the normal use of the dice assembly, the switching element 4 is in the conducting state, and the external power supply 61 supplies power to the timing module 5 normally. The timing module 5 generates timing information at regular intervals when it is powered on. At this time, the control motherboard 3 reads and records the timing information generated by the timing module 5, which indicates that the detachable parts of the dice assembly have not been removed.

[0031] When the detachable parts of the dice board assembly are removed, the switch element 4 detaches from the tray 2 and automatically disconnects. At this time, the timing power supply circuit is de-energized, and the timing module 5 stops generating timing information due to power loss. Furthermore, the control motherboard 3 is equipped with a power module and an alarm module. The power module supplies power to the control motherboard 3 independently. Therefore, even after the switch element 4 is disconnected, the control motherboard 3 can still operate normally. Since the control motherboard 3 cannot read the timing information from the timing module 5, it sends an alarm signal to the manufacturer or administrator through the alarm module. This allows the manufacturer or administrator to immediately receive information that the control motherboard 3 has been disassembled, enabling timely detection of the control motherboard 3 and preventing tampering with its control program, thus ensuring fairness and a positive gaming experience. Specifically, in this embodiment, the alarm module is connected to a terminal. After the alarm module transmits the alarm signal to the terminal, the terminal generates an alarm record based on the alarm signal and alerts the manufacturer or administrator by emitting a buzzer or flashing a warning light. Of course, it is understood that in other embodiments, the terminal could also be a smartphone or a smart mobile device.

[0032] Furthermore, when the external power supply 61 is disconnected, it stops supplying power, and the energy storage element 62 is in a discharging state. Even after discharging, the energy storage element 62 can still supply power to the timing module 5. At this time, the control motherboard 3 can still read the timing information, meaning that the control motherboard 3 will not issue an alarm signal. This effectively prevents the control motherboard 3 from issuing an alarm signal due to power outages or the removal of the external power supply 61, reducing the possibility of erroneous detection by the control motherboard 3 and making the disassembly and detection of the dice board assembly by the control module more accurate and reliable. When the external power supply 61 is reconnected to the timing power supply circuit, the energy storage element 62 stops discharging, and the external power supply 61 continues to supply power to the timing module 5 and the energy storage element 62, enabling the timing module 5 to run again and allowing the energy storage element 62 to charge, maintaining the stored power of the energy storage element 62 and ensuring that the energy storage element 62 always remains charged so that it can continuously provide power to the timing power supply circuit after the external power supply 61 is disconnected.

[0033] It should be noted that the energy storage element 62 described in this embodiment is a supercapacitor. Supercapacitors have the advantages of fast charging and discharging speed and large capacity, enabling the energy storage element 62 to store more electricity. When the energy storage element 62 discharges, it can provide a longer-lasting power supply to the timing module 5, ensuring that the energy storage element 62 can effectively cope with unexpected situations such as temporary power outages. In addition, the energy storage element 62 discharges quickly, and can supply power to the timing module 5 in a timely manner after the external power supply 61 is cut off, preventing the control motherboard 3 from not reading the timing information and issuing an alarm signal due to slow power supply speed. This can effectively reduce the possibility of false alarm triggering and make the disassembly and detection of the dice disk component by the control component more accurate and reliable.

[0034] Example 2: like Figures 2 to 3 As shown in the figure, this embodiment also illustrates a dice plate assembly, which includes a tray 2 and a cover plate 1. The cover plate 1 is mounted on the top of the tray 2, and the cover plate 1 and the tray 2 are closed to form an installation cavity between them. A disassembly warning device is installed in the installation cavity. The disassembly warning device includes a switch element 4, a timing module 5, a timing power supply circuit, and a control module. The control module includes a control main board 3. The cover plate 1, the tray 2, and the control main board 3 are all detachable components. The control module performs disassembly detection based on the disassembly action of the detachable components. Specifically, the disassembly warning device adopts the disassembly warning device of the mahjong machine dice plate assembly as described in Embodiment 1.

[0035] Example 3: This embodiment illustrates a mahjong machine, including a table body. The top of the table body is equipped with a table board and a dice plate assembly. The dice plate assembly is connected to the table body via a lifting assembly. The table board has a window in the middle, and the dice plate assembly is installed inside the window. When the dice plate assembly descends to its lowest position, it closes the window. When the dice plate assembly rises with the lifting assembly, it opens the window to facilitate pushing mahjong tiles into the table body. The dice plate assembly is the same as that described in Embodiment 2.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above.
