Description

Technical Field

[0001] This utility model relates to the field of mahjong machine technology, specifically to a light-sensing detection tile retention mechanism for mahjong machines. Background Technology

[0002] Mahjong is a traditional popular recreational activity. Existing mahjong machines involve operations such as shuffling, sucking in, stacking, pushing, placing, and raising tiles. Placing and raising tiles typically require multiple motors working together. Furthermore, during these processes, the movement can easily cause tiles to jam, making it difficult to place them; therefore, accurate identification of the remaining state of the mahjong tiles on the platform is necessary.

[0003] To accurately identify the status of mahjong tiles on the support platform, the applicant previously applied for patent 2024210562536, "Pressure-Sensitive Tiles Retention Detection Mechanism for Lifting Tiles." This mechanism "has at least one magnetic component embedded in the lifting platform that can magnetically attract mahjong tiles, and a pressure sensor for detecting mahjong tiles is also installed within the lifting platform. The pressure sensor is also electrically connected to the control module via a flexible conductive wire." However, if a foreign object of similar mass falls onto the pressure sensor, it can cause identification anomalies. Furthermore, since mahjong tiles are magnetic, Hall effect switches are prone to false triggering. Therefore, a mechanism capable of accurately identifying the status of tiles on the support platform is needed to avoid these problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to provide a light-sensing detection and card retention mechanism for mahjong machines. By utilizing the magnetic attraction between mahjong cards and magnets, coupled with precise detection of optical signals, it enables intelligent card placement and card raising operations.

[0005] To achieve this technical objective, the present invention provides a light-sensing detection tile retention mechanism for a mahjong machine, characterized in that it includes a driving mechanism, a base shell, and a support platform. Two or more sliding rods are vertically mounted on the base shell, and the sliding rods are slidably mounted on the support platform. The driving mechanism is drivingly connected to the support platform.

[0006] The support platform includes at least one support column. A receiving element and a light-emitting element are installed on the inner wall of the middle part of the support column. A fixing column is integrally formed on the inner side wall of the top of the support column. A return spring and a telescopic shaft are sleeved on the fixing column. A magnet is installed at one end of the telescopic shaft, and a baffle is provided at the other end of the telescopic shaft. When a mahjong tile is placed on the support platform, the telescopic shaft is displaced by the magnetic force of the mahjong tile. The baffle on the telescopic shaft can block or conduct the light path between the receiving element and the light-emitting element to emit a signal.

[0007] Preferably, the telescopic shaft is a hollow columnar structure, the top of the telescopic shaft is provided with an installation groove, the magnet is a ring structure, and the diameter of the inner ring of the magnet is larger than the diameter of the fixed column.

[0008] Preferably, the support platform is composed of two integrally formed support columns, each support column having a hollow structure. One side of each support column has an integrally formed vertically arranged connecting sleeve that can be slidably connected to a sliding rod. The top of each support column has an integrally formed anti-slip groove, and an anti-slip pad is adhered inside the anti-slip groove.

[0009] Preferably, the drive mechanism is composed of a drive motor and a gear set, wherein the drive motor drives the drive platform to move up and down through the gear set.

[0010] Preferably, the fixing column is a hollow structure.

[0011] Preferably, one side of the support platform is provided with a connecting part that can be connected to a gear set, and the other side of the support platform is provided with a limiting member that can control the vertical movement range of the support platform.

[0012] The beneficial effects of this utility model are that it utilizes the magnetic force of the mahjong tiles to interact with the magnet installed on the telescopic shaft, thereby identifying whether there are mahjong tiles on the support platform; this optical detection tile retention mechanism has the advantages of simple structure, accurate identification, easy maintenance, and small space occupation, which is more conducive to the structural layout of the mahjong machine. Using the structure of this utility model, the accuracy of tile loading and unloading is high, and the failure rate can be reduced. Attached Figure Description

Detailed Implementation

[0019] The utility model of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. In order to provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; other embodiments obtained based on the content described in this application without creative effort are all within the scope of protection of this utility model.

[0020] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of clearly describing this embodiment, rather than indicating or implying that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] like Figure 1-5 As shown, the specific embodiment of this utility model is a light-sensing detection card retention mechanism for a mahjong machine, including a drive mechanism 2, a base shell 1 and a support platform 3. Two slide rods 5 are vertically installed on the base shell 1 and are slidably installed on the support platform 3. The drive mechanism 2 is driven to connect with the support platform 3.

[0022] The drive mechanism 2 consists of a drive motor 7, a connecting rod, and a gear set 9. The drive motor 7 drives the connecting rod via the gear set 9 to move the support platform 3 up and down. The gear set 9 includes a drive gear, a fixed gear, a gear ring, and a moving gear. The fixed gear and the gear ring have coincident axes. The drive gear meshes with the fixed gear, and the moving gear meshes with the gear ring. One side of the moving gear is fixedly connected to the connecting rod, and the other side of the moving gear is fixedly connected to the edge of the fixed gear. Through the configuration of the drive mechanism 2, the support platform can move up and down, thereby causing the mahjong tiles to rise and fall.

[0023] The support platform 3 is composed of two integrally formed support columns 4. Each support column 4 has a hollow structure, and one side of each column 4 has an integrally formed vertically arranged connecting sleeve that can slide with the slide rod 5, allowing for vertical movement. One side of the support platform 3 has a connecting part 409 that can be connected to a gear set 9, and the other side of the support platform 3 has a limiting member 410 that controls the vertical movement range of the support platform 3. Furthermore, each support column 4 has three anti-slip grooves 6 at its top, with anti-slip pads 8 adhered inside the grooves 6 to prevent the mahjong tiles from slipping during movement. Each support column 4 has a receiving element 401 and a light-emitting element 402 installed on its inner wall. Each support column 4 has a fixing column 403 installed on its top inner wall. The fixing column 403 is fitted with a return spring 404 and a telescopic shaft 405. The telescopic shaft 405 is a hollow columnar structure. One end of the telescopic shaft 405 is fitted with a ring-shaped magnet 406. The diameter of the inner ring of the magnet 406 is larger than the diameter of the fixing column 403. The magnet 406 can fit around the fixing column 403. The top of the telescopic shaft 405 is provided with a mounting groove 408, in which the return spring 404 can be installed.

[0024] A baffle 407 is provided at the other end of the telescopic shaft 405. When mahjong tiles are placed on the support platform 3, the telescopic shaft 405 is displaced by the magnetic force of the mahjong tiles. The baffle 407 on the telescopic shaft 405 can block or open the optical path between the receiving element 401 and the light-emitting element 402 to emit a signal.

[0025] When no mahjong tiles are placed on the support platform 3, the telescopic shaft 405 automatically droops down. The baffle 407 on the telescopic shaft 405 does not block the light path between the receiving element 401 and the light-emitting element 402, so the light path is open, and the mahjong tiles below can rise or stay in the cavity structure.

[0026] When mahjong tiles are placed on the support platform 3, the telescopic shaft 405 rises due to the magnetic force of the mahjong tiles. The baffle 407 on the telescopic shaft 405 blocks the light path between the conducting receiving element 401 and the light-emitting element 402, thus preventing the mahjong tiles below from rising. The mahjong tiles on the support platform 3 can descend, or the mahjong tiles remaining in the cavity structure can rise or fall.

[0027] The detection and retention mechanism of this application can utilize the magnetic force of mahjong tiles to identify whether there are mahjong tiles on the carrier platform by interacting with the magnet installed on the telescopic shaft (attracting or repelling them). This optical detection and retention mechanism has the advantages of simple structure, accurate identification, resistance to interference, easy maintenance, and small space occupation. It is also more conducive to the structural layout of mahjong machines. The structure of this utility model has high accuracy in placing and raising tiles and can further reduce the failure rate.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present utility model should be included within the protection scope of the present utility model.
