Example III

Referring to fig. 5 to 7, this embodiment is different from the first embodiment in that: the card lifting structure in the flat pushing card lifting device is optimized, and the card lifting structure is specific: the flat-pushing card lifting device comprises a card lifting support 310, a card lifting motor 350, a card lifting plate 320 and a card lifting transmission assembly, wherein the card lifting transmission assembly comprises two card lifting rocker arms 360 and rocker arm connecting rods, the card lifting rocker arms 360 are arranged at intervals along the length direction of the card lifting plate 320, the two card lifting rocker arms 360 are rotationally connected to the card lifting support 310, and the rocker arm connecting rods drive the two card lifting rocker arms 360 to swing synchronously so as to drive the card lifting plate 320 to do lifting motion. The tile pushing structure of the tile pushing and lifting device comprises a tile bearing plate 330 for bearing the mahjong tiles and a tile pushing plate 340 for pushing the mahjong tiles on the tile bearing plate 330 to the tile lifting plate 320, wherein the tile lifting structure and the tile pushing structure can share one tile lifting motor 350, and the tile pushing structure can also be independently provided with the tile pushing motor.

In the flat-pushing card lifting device in the prior art, a card lifting motor and a card lifting rocker arm are driven by a gear mechanism, one gear of the gear mechanism is driven by the card lifting motor to rotate, kinetic energy is transmitted to the card lifting rocker arm by the meshing transmission of the gear, and a card lifting plate is driven to do lifting motion by the swing of the card lifting rocker arm. The gear mechanism makes the structure of the flat-pushing tile lifting device complex, is inconvenient to assemble and maintain, the whole thickness of the flat-pushing tile lifting device is limited by the gear mechanism and cannot be further reduced, and the automatic mahjong machine still needs a larger longitudinal space to meet the assembly of the flat-pushing tile lifting device, so that the light and thin design of the automatic mahjong machine is not facilitated.

In this embodiment, adopt rocking arm connecting rod to replace gear mechanism to realize the transmission, rocking arm connecting rod, two to rise tablet rocking arm and rise tablet board and constitute simplest connecting rod motion, make the structure of flat push lift tablet device simpler on the one hand, reduced the design degree of difficulty and the cost of flat push lift tablet device, also be convenient for assemble and maintenance more, on the other hand, rocking arm connecting rod is the rod-shaped component, and the requirement is lower to the installation space for the thickness of flat push lift tablet device can further reduce, saves the assembly space of flat push lift tablet device, makes automatic mahjong machine can design more frivolously. In particular, in combination with the automatic mahjong machine described in the foregoing embodiment, in order to achieve the technical effect described in the first embodiment, the tile lifting device needs to be lifted by a certain height relative to the bottom plate, so that a gap for yielding the tile shuffling tray is formed between the bottom of the tile lifting device and the bottom plate. Compared with the prior art, the thickness of the flat-pushing card-lifting device is further reduced, so that a gap of a yielding card-shuffling tray is formed between the flat-pushing card-lifting device and the bottom plate on the premise of not increasing the thickness of the whole machine, and the layout requirement of the flat-pushing card-lifting device is met.

According to the flat-pushing card lifting device of the present embodiment, one of the card lifting rocker arms 360 is configured as a lever-type rocker arm (e.g., the card lifting rocker arm 360 on the left side in fig. 7), the rocker arm link includes a first link 371, a second link 372 and a third link 373 which are sequentially rotatably connected, wherein the first link 371 is rotatably connected to the lower end of the lever-type rocker arm, the third link 373 is rotatably connected to the other card lifting rocker arm 360, the second link 372 is rotatably connected to the card lifting bracket 310, the first link 371 and the third link 373 are kept parallel to the card lifting plate 320 during movement, and the card lifting motor 350 drives the first link 371 to reciprocate in the length direction thereof. As shown in fig. 8, when the card is lifted, the card lifting motor 350 drives the first link 371 to move rightward, the left end of the first link 371 drives the left card lifting rocker 360 to swing counterclockwise, the right end of the first link 371 drives the second link 372 to rotate counterclockwise, and the counterclockwise rotation of the second link 372 drives the third link 373 to move leftward, so that the right card lifting rocker 360 is driven to swing counterclockwise, and thus the two card lifting rockers 360 swing counterclockwise synchronously to push the card lifting plate 320 upward. As shown in fig. 9, when the card lifting plate 320 is required to descend, the card lifting motor 350 drives the first link 371 to move leftwards, the left end of the first link 371 drives the left card lifting rocker 360 to swing clockwise, the right end of the first link 371 drives the second link 372 to rotate clockwise, and the clockwise rotation of the second link 372 drives the third link 373 to move rightwards, so that the right card lifting rocker 360 is driven to swing clockwise, and thus the two card lifting rockers 360 swing clockwise synchronously, so that the card lifting plate 320 descends.

According to the characteristics of the link motion mechanism, it is conceivable that, besides the above scheme, the card lifting motor 350 drives the second link 372 or the third link 373 in the rocker links and drives one of the two card lifting rockers 360, so that the whole link motion mechanism can be driven to act, and the card lifting plate 320 can be lifted.

In this embodiment, the card lifting motor 350 drives the card lifting transmission assembly through the gear assembly, the gear assembly includes an output gear 351 and a transmission gear 352, the card lifting motor 350 is installed at the bottom of the card lifting support 310, the output gear 351 is installed on the output shaft of the card lifting motor 350, the transmission gear 352 is meshed with the output gear 351, a transmission block 353 is arranged on the side face of the transmission gear 352, a transmission seat 374 is arranged on a first connecting rod 371 of the rocker arm connecting rod, a transmission groove 375 is arranged on the transmission seat 374, the transmission block 353 is matched in the transmission groove 375 and can slide up and down relative to the transmission groove 375, the card lifting motor 350 outputs torque to drive the transmission gear 352 to rotate, the transmission seat 371 is stirred by the transmission block 353 to drive the first connecting rod 371, and the forward and backward rotation of the card lifting motor 350 is controlled, namely the movement direction of the first connecting rod 371 is controlled, and the lifting movement of the card lifting plate 320 is controlled.
