[0002] As people's living standards improve, more and more entertainment options are available. Mahjong, known for its entertaining and mentally stimulating properties, has become increasingly popular. Simultaneously, with technological advancements, the use of automatic mahjong machines is becoming increasingly widespread. Traditional household automatic mahjong machines require the user to operate the control buttons on the fully automatic mahjong table, raising the operating panel to reveal the card slot on the table. The user then pushes the completed magnetic mahjong tiles onto the tabletop before retracting the operating panel. The pre-assembled mahjong tiles are then lifted onto the tabletop by a lifting mechanism, allowing the player to continue playing, and the cycle continues.

[0003] When people go out, they often play mahjong together for entertainment. However, home mahjong machines are large and inconvenient to carry, so small portable mahjong machines have emerged.

[0004] The lifting structure of the portable mahjong machine in the prior art is similar to the driving structure of the traditional non-portable mahjong machine. It uses multiple motors to drive the lifting, which occupies internal space and is costly. Therefore, it needs to be further improved to reduce the size and facilitate use. Utility Model Content

The bottom of the card feeding mechanism is fixedly set on the top of the drag plate.

[0027] The card entry mechanism includes a card entry cover plate 2, a fixed frame 21 and a cover plate driving unit. The card entry cover plate 2 is arranged in a shape corresponding to the card entry port 12. The card entry cover plate 2 is divided into two symmetrical pieces. The close parts of the two card entry cover plates 2 serve as rotating ends, and the ends away serve as movable ends. The card entry cover plates 2 are rotatably connected to the upper part of the fixed frame 21 through the rotating ends. Specifically, a support rod 23 is provided on the outside of the fixed frame 21. The support rod 23 is L-shaped. Two groups of support rods 23 are symmetrically arranged on both sides of the fixed frame 21 in a lifting shape. A hinge 22 is provided on the top of the support rod 23. One end of the hinge 22 is fixed on the top of the support rod 23, and the other end is fixed on the rotating end of the card entry cover plate 2, so that the card entry cover plate 2 is hinged to the support rod 23 for rotation.

[0028] The cover drive unit is used to control the rotation angle of the card entry cover 2, that is, the opening size of the card entry port 12. The cover drive unit includes a guide protrusion 26, a rotating shaft 25, a rotating support rod 24 and a card entry motor 3. The guide protrusion 26 is arranged in a trapezoidal shape, and one side of the guide protrusion 26 is arranged to be inclined and abutted against the rotating shaft 25 up and down. The rotating shaft 25 can be arranged in the form of a rotating rod or a rotating bearing. This structure is a prior art and will not be described here. The rotating shaft 25 is connected to the rotating support rod 24, and the rotating support rod 24 is driven by the card entry motor 3. A linkage block 32 is provided on the shaft of the card entry motor 3, and the linkage block 32 is connected to the two rotating support rods 24. A movable groove is provided on the side of the fixed frame 21, and the rotating support rod 24 is sleeved in the movable groove and moves horizontally. A motor seat 31 is provided at the bottom of the fixed frame 21, and the card entry mechanism is fixed to the support plate 13 through the motor seat 31. A console is provided on the top of the fixing frame 21 for interacting with the operator.

[0029] The shuffling mechanism includes a shuffling tray 8 and a shuffling motor 9. The shuffling tray 8 has guide wheels at its bottom and shuffling protrusions at its top. Meshing teeth are located around the shuffling tray 8. The shuffling motor 9 is located on the side of the shuffling tray 8 and is driven by a drive gear that meshes with the outer gear of the shuffling tray 8. An arc-shaped baffle is located above the shuffling tray 8 to block and guide the mahjong tiles. The shuffling tray 8 rotates and guides the tiles to the bottom of the card suction mechanism through the notches provided in the baffle.

[0030] The card suction mechanism is as follows Figure 10 , including a card suction wheel 72, a conveyor belt 7 and a conveyor belt driving device. The conveyor belt 7 is a flexible rubber conveyor belt. The card suction wheel 72 is provided with a magnetic body, which is attracted by the magnets provided in the mahjong tiles so that the mahjong tiles are transferred from the shuffling plate 8 to the conveyor belt 7. The conveyor belt driving device includes a driving wheel 73, a transmission wheel 74 and a pulley driving motor 71. The driving wheel 73 is coaxially arranged with the pulley driving motor 71, and the transmission wheel 74 is sleeved in the conveyor belt 7. Figure 11 The transmission wheel 74 is a drum-shaped transmission wheel. The middle part of the drum-shaped transmission wheel is drum-shaped, and the two ends gradually narrow outward. When the conveyor belt 7 rotates, if the conveyor belt 7 is deviated from the middle part of the drum-shaped transmission wheel by external force, the surface of the conveyor belt 7 farther from the center of the drum-shaped transmission wheel shrinks and the tension decreases, while the tension of the conveyor belt 7 near the middle part is relatively large. When the area with large tension fits with the surface of the drum-shaped transmission wheel, the relative pressure is greater, resulting in greater friction, thereby causing the conveyor belt 7 to move to the side with greater friction, so that the previously deviated conveyor belt 7 returns to the right position. Other settings and uses of the card suction mechanism are existing technologies and will not be described here.

[0031] A tile pushing mechanism is located at the rear of the card suction mechanism to push the tiles and arrange them in rows. The mechanism comprises a tile pushing motor 61, a tile pushing cam 62, a tile pushing guide rod 63, and a tile pushing plate 6. Based on sensor signals, the tile pushing motor 61 drives the tile pushing cam 62 to rotate. The rear portion of the tile pushing plate 6 is movably coupled to the tile pushing guide rod 63. The tile pushing cam 62 drives the tile pushing plate 6 to reciprocate, pushing the stack of tiles to one side and arranging them.

[0032] The card pushing device includes a card pushing plate 5, a card pushing motor 51, a card pushing cam 53, a card pushing guide rod 54, and a motion guide rod 55. The card pushing motor 51 has a card pushing cam 53 disposed on its output shaft, which is then equipped with a push plate guide rod. The card pushing guide rods 54 are arc-shaped, and a shifting rod is disposed between two sets of the card pushing guide rods 54. The card pushing cam 53 movably abuts against the shifting rod. The card pushing cam 53 rotates to abut against the shifting rod, causing the card pushing guide rods 54 to move, thereby rotating and pushing the card pushing plate 5. Motion guide rods 55 are evenly disposed on both sides of the rear of the card pushing guide rod 54 to stabilize the movement of the card pushing plate 5.

[0033] The lifting mechanism includes a lifting platform 4, a guide unit for the lifting platform 4, and a drive unit for the lifting platform 4. The guide unit for the lifting platform 4 includes a guide rail 41, a linear bearing 42, a guide plate 43, and a lifting cam 44. The guide rail 41 is vertically arranged on the support plate 13, and the linear bearing 42 is movably sleeved on the guide rail 41. The outer wall of the linear bearing 42 is fixedly connected to one side of the lifting platform 4. The top of the guide plate 43 is fixedly arranged on the lifting platform 4, and a guide slot is provided at the bottom of the guide plate 43. The guide slot is concave in the middle and higher on both sides. The front end of the lifting cam 44 is movably sleeved in the guide slot to drive the guide plate 43 to move up and down.

[0034] The lift platform 4 drive unit includes a drive gear shaft 52 and a lift gear shaft 45. Two symmetrical sets of drive gear shafts 52 rotate coaxially with the card-pushing motor 51. The drive gear shafts 52 and the lift gear shaft 45 are intermeshing bevel gears. The two sets of drive gear shafts 52 are coaxially arranged on either side of the card-pushing cam 53. The shaft of the lift cam 44 is coaxially arranged with the output end of the lift gear shaft 45.

[0035] The controller controls the operation of the sensor and the motor.

[0036] The energy storage mechanism includes a power module and a rechargeable battery. The power module charges the battery or directly supplies power to the electrical devices. The rechargeable battery is disposed within the housing 1 and is electrically connected to the electrical devices.

[0037] Usage process: The operator operates the control console to cause the card-feeding motor 3 to rotate the rotating support rod 24, which in turn drives the rotating shaft 25 to abut against the guide protrusion 26 and move toward the card-feeding cover plate 2. The card-feeding cover plate 2 rotates and droops under the action of gravity, exposing the inner cavity of the housing 1. After pushing the mahjong tiles into the card-feeding port 12, the operator operates the control console to cause the card-feeding motor 3 to move in the opposite direction, causing the rotating shaft 25 to move away from the card-feeding cover plate 2 along the guide protrusion 26, pushing the card-feeding cover plate 2 up and engaging the card-feeding port 12.

[0038] Mahjong tiles entering through the card inlet 12 fall onto the shuffling tray 8, which rotates and shuffles the tiles. During this rotation, the tiles are gradually pushed to the entrance of the card suction mechanism. The tiles, attracted by the card suction mechanism, are transported to the rear frame along the conveyor belt 7. After the sensor counts the tiles, the two stacked tiles are pushed to one side by the push motor 61, which drives the push plate 6 to make room for the next set of tiles.

[0039] When the number of mahjong tiles counted by the sensor reaches a set number, the lifting platform 4 is in the lower position. The push motor 51 drives the push cam 53, which in turn moves the push guide rod 54, thereby moving the mahjong tiles onto the lifting platform 4 via the push plate 5. After the push plate 5 returns to its position above the lifting platform 4, the lift cam 44 drives the lifting platform 4 upward, raising the four already arranged mahjong tile sets to the height of the panel 11.
