Description

Technical Field

[0001] This invention relates to the field of mahjong machine technology, and more specifically to a mahjong machine layout structure. Background Technology

[0002] Chinese utility model patent CN221846023U discloses a card-pulling mechanism and a mahjong machine. This mahjong machine is a roller coaster-style mahjong machine that uses a card-pulling mechanism to handle the tiles. The layout of the aforementioned mahjong machine is as follows: Figure 24 As shown, it has the following technical defects:

[0003] (1) The tile lifting plate and the tile conveying mechanism are arranged in a layout that is close to the end. As a result, the total length of the tile lifting plate and the tile conveying mechanism is relatively large, and they need to be placed closer to the edge of the mahjong machine. This makes the tile stack that is lifted to the mahjong machine table closer to the edge of the mahjong machine. This is not comfortable for the user, who needs to push the tile stack towards the center, resulting in a poor user experience.

[0004] (2) The area where the ends of adjacent lanes overlap is located at the corner of the mahjong table. At the horizontal and vertical center lines of the mahjong machine, adjacent lanes do not overlap. The lanes are arranged abnormally close to the edge of the mahjong machine. The tile-lifting plate that connects to the lanes is also too close to the edge, causing the mahjong tile stacks that are lifted to the table to be closer to the edge. This also makes the user's comfort poor and the experience bad.

[0005] (3) During the lifting process, the free end of the lifting plate descends to be flush with the entrance and exit points of the tile path, covering the tile holder. At this time, the tile-pulling mechanism transports all the mahjong tiles from the tile path to the lifting plate. In this layout, the angle between the lifting plate and the tile path needs to be considered to ensure that the mahjong tiles can be smoothly transported to the lifting plate. Usually, the lifting plate is placed closer to the edge of the mahjong machine, resulting in a smoother connection with the tile path. However, the closer the lifting plate is to the edge of the mahjong machine, the closer the stack of mahjong tiles on the table is to the edge. This is less comfortable for the user, who needs to push the stack of tiles towards the center, resulting in a poor user experience. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an optimized layout structure for a mahjong machine, so that the stack of mahjong tiles raised to the tabletop is closer to the center, thereby solving the technical defects of poor user comfort and poor user experience in the prior art.

[0034] Compared with the prior art, the mahjong machine layout structure of this embodiment has the following advantages:

[0035] (1) In the direction of the normal C of the lifting plate, the lifting plate, the stacking and pushing integrated module, and the stacking area D are arranged radially from the inside to the outside. This layout changes the traditional layout structure where the lifting plate and the conveying plate mechanism are connected end to end, reduces the layout size of the lifting plate in the length direction, and makes the lifting plate closer to the center of the mahjong tiles. This makes the stack of mahjong tiles that rises to the mahjong machine table closer to the center of the mahjong machine, with a larger distance from the edge of the mahjong machine, resulting in better user comfort and experience.

[0036] (2) Adjacent card storage slots are arranged side-by-side radially to form an overlapping area D, with the card inlet / outlet of the card storage slot 80 located inside the overlapping area. Either overlapping area D is traversed by either the transverse centerline A or the longitudinal centerline B. The advantage of this arrangement is that the card inlet / outlet of the card storage slot is closer to the center of the mahjong machine, and the upper end of the card lifting plate connects to the inlet / outlet, allowing the card lifting plate to also be positioned closer to the center of the mahjong machine. Correspondingly, the mahjong tile stack raised to the mahjong machine tabletop is closer to the center, and the distance between the mahjong tile stack and the edge of the mahjong machine is larger. For the user, this larger distance results in better comfort and a better experience. Attached Figure Description

[0061] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0062] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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 invention.

[0063] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0064] This embodiment presents a mahjong machine layout structure, such as... Figure 1 As shown, the mahjong machine includes a card storage slot 80, a card lifting plate 70, and a stacking and pushing integrated module 110. The mahjong machine has a horizontal center line A and a vertical center line B, and the card lifting plate has a normal line C passing through the center of the mahjong machine.

[0065] In this embodiment, four sets of card storage slots 80 are provided. A unique feature of this embodiment is that adjacent card storage slots 80 are arranged side-by-side radially to form an overlapping area D, with the card inlet / outlet of each card storage slot 80 located inside the overlapping area. Each overlapping area D is traversed by either the transverse centerline A or the longitudinal centerline B. The advantage of this arrangement is that the card inlet / outlet of the card storage slot is closer to the center of the mahjong machine, and the upper end of the card-lifting plate connects to the inlet / outlet, allowing the card-lifting plate to also be positioned closer to the center of the mahjong machine. Correspondingly, the stack of mahjong tiles raised to the mahjong table is closer to the center, and the distance between the stack of mahjong tiles and the edge of the mahjong machine is larger. For the user, this larger distance improves comfort and enhances the overall experience.

[0066] In this embodiment, the stacking and pushing integration module 110, as follows: Figures 2-6 As shown, it includes a housing 60, a stacking drive mechanism, a card lifting mechanism 20, a card pushing mechanism 30, and a card conveying mechanism 50. The housing 60 has an internal mounting cavity 62.

[0067] In this embodiment, as Figures 4-6 As shown, the stacking drive mechanism includes a stacking motor 10, a main drive gear 11, a card-lifting drive gear 21 for driving the card-lifting mechanism 20, and a card-pushing drive gear 31 for driving the card-pushing mechanism 30. The main drive gear 11 is mounted on the output shaft of the stacking motor 10. The card-pushing drive gear 31 and the card-lifting drive gear 21 are located on opposite sides of the main drive gear 11 and mesh with it.

[0068] In this embodiment, the card-lifting drive gear 21 is mounted on the card-lifting drive shaft 211 via a first one-way mechanism 212, and the card-stacking drive gear 31 is mounted on the card-stacking drive shaft 311 via a second one-way mechanism 312. Furthermore, the transmission directions of the first one-way mechanism 212 and the second one-way mechanism 312 are opposite. Thus, the forward and reverse rotation of the stacking motor 10 drives the card-lifting mechanism 20 and the card-stacking mechanism 30 to operate, respectively.

[0069] The unique feature of this embodiment lies in the structural design and layout where the card-pushing drive gear 31 and the card-lifting drive gear 21 are located on both sides of the main drive gear 11. This arrangement places the card-lifting mechanism 20 and the card-pushing mechanism 30 on both sides of the card-lifting motor 10, extending the installation space to both sides of the card-lifting motor 10. Compared to existing technologies, this reduces the axial installation dimensions of the card-lifting motor 10. This structural form optimizes the internal space layout of the mahjong machine, resulting in higher space utilization. Furthermore, this layout provides a better structural foundation for integrating the card-lifting and card-pushing mechanisms into a single unit.

[0070] It should be noted that the first one-way mechanism 212 and the second one-way mechanism 312 in this embodiment can be any one of the one-way bearings, one-way clutches or one-way ratchet mechanisms in the prior art. There is no restriction in this embodiment, but one-way bearings are preferred.

[0071] In this embodiment, the card-lifting mechanism includes a first transmission gear 22, a second transmission gear 23, a rocker arm gear 24, a card-lifting rocker arm 26, and a rocker arm connecting rod 25. Wherein, as... Figure 5 As shown, the first transmission gear 22 is coaxially arranged with the lifting drive gear 21, and the first transmission gear 22 is fixedly connected to the lifting drive shaft 211. The second transmission gear 23 is located between the first transmission gear 22 and the rocker arm gear 24, and the second transmission gear 23 meshes with the first transmission gear 22 and the rocker arm gear 24 respectively. The power output by the stacking motor 10 is transmitted to the rocker arm gear 24 in sequence through the main drive gear 11, the first transmission gear 22 and the second transmission gear 23.

[0072] In this embodiment, as Figure 2As shown, the first transmission gear 22, the second transmission gear 23, the rocker arm gear 24, the tile-raising rocker arm 26, and the rocker arm connecting rod 25 are disposed on one side of the outer side of the machine housing, which is the side close to the center of the mahjong machine.

[0073] In this embodiment, as Figure 7 As shown, the rocker arm gear 24 is provided with a first eccentric column 241.

[0074] In this embodiment, as Figure 6 , Figure 9 As shown, the lower end of the lifting rocker arm 26 is provided with a first hinge shaft 261 for hinged engagement with a fixedly mounted hinge seat 27. The upper end of the lifting rocker arm 26 is provided with a lifting drive roller 262 for engaging with the lifting plate to drive the lifting plate 70 to rise and fall. The lifting rocker arm 26 is provided with a second hinge shaft 263 for hinged engagement with the rocker arm connecting rod 25, and the second hinge shaft 263 is located between the first hinge shaft 261 and the lifting drive roller 262.

[0075] In this embodiment, as Figure 8 As shown, one end of the rocker arm connecting rod 25 is hinged to the first eccentric column 241 through the first hinge hole 251, and the other end of the rocker arm connecting rod 25 is hinged to the second hinge shaft 263 on the lifting rocker arm 26 through the second hinge hole 252. Thus, the rotational motion of the rocker arm gear 24 can be converted by the rocker arm connecting rod 25 into the oscillation of the lifting rocker arm 26 around the first hinge shaft 261, thereby driving the lifting plate to rise and fall.

[0076] The card-stacking mechanism in this embodiment, such as Figures 4-6 As shown, the assembly includes a third transmission gear 32, a cam 33, a card holder 36, a card holder rocker arm 37, a slide rail 34, a slider 35, and a card pusher head 38. The third transmission gear 32 is coaxial with the card-pushing drive gear 31, and is fixedly mounted on the card-pushing drive shaft 311. Figures 10-11 As shown, the cam 33 is provided with an external gear 333 that meshes with the third transmission gear 32, and the third transmission gear 32 and the stacking pusher drive gear 31 are respectively located on both sides of the slider 35.

[0077] like Figure 2 As shown, in this embodiment, the card holder 36 and the card pusher 38 are located on one side of the outer casing near the end of the casing, and the card holder and the card pusher are located on the same side of the outer casing as the rocker arm gear.

[0078] In this embodiment, as Figures 10-11As shown, the cam 33 is disposed in the mounting cavity, a cam track groove 331 is provided on one side end face of the cam 33, and a second eccentric column 332 is provided on the other side end face of the cam 33.

[0079] In this embodiment, as Figure 13 As shown, the plate holder 36 is provided with a vertical guide portion 361, and a horizontally extending waist-shaped transmission groove 362 is provided on one side of the plate holder 36.

[0080] In this embodiment, as Figure 14 As shown, one end of the tile-bearing rocker arm 37 is provided with a first stacking tile transmission roller 371 adapted to the cam track groove 331, and the other end of the tile-bearing rocker arm 37 is provided with a second stacking tile transmission roller 372 adapted to the waist-shaped transmission groove 362. Furthermore, the tile-bearing rocker arm 37 is also provided with a hinge portion 373 located between the first stacking tile transmission roller and the second stacking tile transmission roller. The tile-bearing rocker arm 37 is hinged to the frame inside the mahjong machine through the hinge portion 373.

[0081] In this embodiment, the transmission route of the transmission mechanism is as follows: the power of the stacking motor 10 is transmitted to the cam 33 in sequence via the main drive gear 11 and the third transmission gear 32. Based on the cooperation between the cam track groove 331 and the first stacking card transmission roller 371, the card holder rocker arm 37 is driven to swing around the hinge part 373. Then, through the cooperation between the second stacking card transmission roller 372 and the waist-shaped transmission groove 362, the card holder 36 is driven to rise and fall.

[0082] In this embodiment, as Figures 4-6 As shown, the slide rail 34 is horizontally fixed in the mounting cavity of the housing, and the slider 35 is slidably connected to the slide rail 34, as shown. Figure 12 As shown, the slider 35 has a slider track groove 351 on the side facing the cam 33 for accommodating the second eccentric column 332. Based on the cooperation between the second eccentric column 332 and the slider track groove 351, the rotational motion of the cam 33 is converted into the reciprocating movement of the slider 35 on the slide rail 34.

[0083] In this embodiment, as Figure 6 As shown, it also includes a connecting arm 39 fixedly connected to the slider 35. The free end of the connecting arm 39 is provided with a reference shaft 391. The pusher head 38 is provided with a connecting arm 381, and the free end of the connecting arm 381 is connected to the reference shaft 391.

[0084] In this embodiment, the connection between the connecting arm 381 and the reference shaft 391 can include two methods: one is that the reference shaft is a fixed shaft, and the connecting arm is rotatably engaged with the reference shaft; the other is that the reference shaft is a rotating shaft, and the connecting arm is fixedly connected to the reference shaft. Regardless of the connection method, the pusher head 38 can swing around the reference shaft 391. Accordingly, to enable the pusher head 38 to return to its original position after swinging around the reference shaft 391, a reset elastic element 310 should be provided. The reset elastic element 310 can be a compression spring or a torsion spring located at the reference shaft.

[0085] like Figure 4 , Figure 5 As shown, the card-carrying mechanism 50 of this embodiment includes a card-suction wheel 52, a conveying mechanism 53, and a drive assembly for driving the card-suction wheel. Figure 2 As shown, in this embodiment, the card suction wheel and the conveying mechanism are disposed in the mounting cavity. The end of the mounting cavity away from the card holder is provided with a card conveying outlet 61. The driving component is disposed on the outside of the housing away from the rocker arm gear.

[0086] In this embodiment, the driving component includes a drive motor 40, a drive gear 41 mounted on the output shaft of the drive motor, and a driven gear 51 meshing with the drive gear. The driven gear 51 is coaxially and fixedly connected to the card-collecting wheel 52. The drive motor 40 drives the card-collecting wheel 52 to rotate, thereby conveying the mahjong tiles to the conveying mechanism 53 and sending them out of the conveying mechanism 50 through the card-collecting outlet 61.

[0087] In this embodiment, preferably, the conveying mechanism includes multiple rollers 531 arranged side by side. Each roller 531 has a transmission gear 532 at its end. The suction wheel 52, on its side away from the driven gear, also has a transmission gear 54 coaxially and fixedly connected to it. The mechanism also includes transition gears 533 located between the transmission gear 532 and the transmission gear 532, and between adjacent transmission gears 532. Thus, during the rotation of the suction wheel, the interaction between the transmission gear 54, the transition gear 533, and the transmission gear 532 provides conveying power for the mahjong tiles, ensuring efficient delivery of the tiles.

[0088] The special feature of this embodiment is that, through the modular design of multiple mechanisms, the lifting, stacking, and conveying of the cards are integrated into one module, making the function of the module more concentrated. The modular design improves assembly efficiency and the ease of disassembly and assembly during maintenance.

[0089] In this embodiment, as Figures 15-16 As shown, the card holder 36 is adjacent to the card delivery outlet 61 of the card delivery mechanism 50 and the card inlet / outlet of the card storage trough 80, respectively. Figure 19As shown, the pusher head 38 includes a pusher plate 381 and a pusher linkage 384. The upper surface of the pusher linkage 384 is a pass surface 382 for accommodating mahjong tiles.

[0090] As a special feature of this embodiment, such as Figure 15 , Figure 17 As shown, after the free end of the card-lifting plate 70 descends, a card-passing connection area E is provided between the free end of the card-lifting plate 70 and the card-in / out port of the card storage slot 80.

[0091] In this embodiment, as Figure 17 As shown, the side of the card holder 36 away from the card storage slot 80 is provided with a second receiving area to accommodate the card pusher plate 381. After the free end of the card lifter plate 70 descends, it drives the card pusher linkage 384 to descend, and the card pusher plate 381 enters the first receiving area. The upper surface of the card pusher linkage 384 is a card-passing surface 382 that can accommodate the passage of mahjong tiles 100. This card-passing surface 382 connects to the side of the card holder 36 away from the card storage slot 80, and the free end of the card lifter plate 70 connects to the card-passing surface 382 of the card pusher linkage. Thus, the card-passing connection area E in this embodiment includes the upper surface of the card holder 36 and the card-passing surface 382 of the card pusher linkage.

[0092] As an equivalent implementation of this embodiment, the position of the card-lifting plate 70 can also be configured such that, after its free end descends, the free end of the card-lifting plate directly connects to the side of the card-receiving seat 36 away from the card storage slot 80. With this configuration, the card-passing connection area E only includes the upper surface of the card-receiving seat 36.

[0093] As a preferred embodiment, in this case, Figure 19 As shown, the pusher rod 384 is provided with a recessed step 383 to accommodate the end of the lifting plate. With this configuration, the upper surface of the lifting plate 70 can connect more smoothly with the passing surface 382, ​​reducing the resistance of the mahjong tiles passing through.

[0094] In this embodiment, as Figure 20 As shown, after shuffling, all mahjong tiles 100 are located in the storage slot 80. When playing tiles, as... Figure 21 As shown, the free end of the tile-lifting plate 70 descends, and the tile-pulling mechanism drives the tile-pulling head 90 to push the mahjong tiles onto the tile-lifting plate via the tile-passing connection area E. When the tile-pulling head 90 is located at its extreme position near the tile inlet / outlet opening within the tile storage slot 80, it covers the tile-passing connection area E. It should be noted that the tile-pulling mechanism can utilize existing technology, and its specific structure will not be described in detail in this embodiment.

[0095] In this embodiment, by setting the card-passing connection area E, the included angle between the card storage slot and the card-lifting plate can be set smaller, meaning the card-lifting plate can be positioned closer to the center of the mahjong machine. With this arrangement, the stack of mahjong tiles raised to the mahjong table is closer to the center of the machine, and the distance between it and the edge of the table is greater. For the user, this larger distance between the stack of mahjong tiles and the edge of the mahjong machine results in better comfort and a better user experience.

[0096] In this embodiment, in order to ensure that the pull-tile head 90 can cover the tile-passing connection area E and ensure that the mahjong tile is pushed into place, such as... Figure 22 As shown, the card-pulling head in this embodiment includes two card-pulling units connected end to end, namely card-pulling unit 91 and card-pulling unit 92, which are rotatably connected to each other. With this configuration, the card-pulling head can adapt to large angle changes in the card-passing connection area E, thereby ensuring that the mahjong tiles are pushed into place.

[0097] In this embodiment, the front of the card-pulling unit 91 is provided with a card-pushing part 691, and the rear is provided with a connecting rod 912 for connecting with the card-pulling unit 92. A first hinge hole 913 is provided near the end of the connecting rod 912. Correspondingly, the card-pulling unit 92 is provided with a connecting rod groove 923 for accommodating the connecting rod 912 and a second hinge hole 922 corresponding to the first hinge hole 913. A pin can be inserted into the first hinge hole 913 and the second hinge hole 922 to achieve a rotatable connection between them. The rear of the card-pulling unit 92 is provided with a connecting part 921 for connecting with the card-pulling mechanism.

[0098] It should be noted that the number of card-pulling units can also exceed two, thus adapting to card-passing connection areas E with different lengths and angles.

[0099] Another implementation of this embodiment, such as Figure 23 As shown, a first receiving area is provided between the card holder 36 and the card inlet / outlet of the card storage slot 80 to accommodate the card pusher plate 381. After the free end of the card lifting plate 70 descends, it drives the card pusher linkage to descend, and the card pusher plate 381 enters the first receiving area. The card pusher linkage 384 covers the card holder 36, and the card-passing surface 382 of the card pusher linkage connects with the card inlet / outlet of the card storage slot 80. The free end of the card lifting plate 70 connects with the card-passing surface 382 of the card pusher linkage. In this embodiment, the card-passing connection area E is the card-passing surface 382 covering the card holder 36.

[0100] In this embodiment, as Figure 1 As shown, the overlapping area D is located outside the stacking and pushing integrated module 110, and the lifting plate is disposed inside the stacking and pushing integrated module. In the direction of the normal C, the lifting plate, the stacking and pushing integrated module and the overlapping area D are arranged radially from the inside to the outside.

[0101] This layout changes the traditional... Figure 24 The lifting plate and the conveying plate mechanism shown are arranged end to end. By reducing the length of the lifting plate, the lifting plate is positioned closer to the center of the mahjong tiles. This results in the mahjong tile stack that is lifted to the tabletop being closer to the center of the mahjong machine, with a larger gap between it and the edge of the machine. This improves user comfort and overall experience.

[0102] In summary, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
