Description

Technical Field

[0001] The invention relates to the technical field of mahjong machines, in particular to a foldable and mobile multifunctional base for mahjong machines. Background Art

[0002] A mahjong machine is a mechatronic device that can automatically shuffle, code and deal cards, greatly simplifying the preparation process of traditional mahjong games. In order to enhance the flexibility of the mahjong machine and meet the needs of players in different occasions, most mahjong machines are moved by installing universal wheels on the base, and the self-locking function of the universal wheels is used to fix the position of the mahjong machine after it is moved to the appropriate position.

[0003] However, in actual use, due to the differences in ground conditions, if the mahjong machine is moved to an area with uneven terrain or a slight slope, the machine body may easily tilt, which greatly affects the player's gaming experience and reduces the comfort of playing cards. If the player plays cards more intensely, the mahjong machine may vibrate, and the vibration may cause the table top to be unstable, resulting in mahjong tiles falling. This not only destroys the player's gaming experience, but also requires the player to manually pick up the fallen mahjong tiles. In addition, the intense card-playing process may be accompanied by loud movements and noises, and the mahjong machine may generate additional noise in an unstable state (i.e., a vibrating state), which further destroys the player's gaming experience and is not practical.

[0035] A square frame is installed at the bottom end of the spherical frame, and its interior is connected to the interior of the square frame. The internal space of the square frame is an oil chamber 23, and extrusion oil is arranged in the oil chamber 23, and an extrusion plate 24 is sealed and slidably connected therein. The extrusion oil is located between the airbag 22 and the extrusion plate 24. An extrusion rod 25 is installed at the bottom end of the extrusion plate 24. The bottom end of the extrusion rod 25 penetrates the inner bottom wall of the oil chamber 23 and the inner wall of the first bottom plate 1, and extends toward the corresponding buffer groove 5. The bottom ends of the two extrusion rods 25 are respectively connected to the two universal wheels 3. The bottom end of the extrusion rod 25 in the second stable adjustment mechanism penetrates the inner bottom wall of the oil chamber 23 and the inner wall of the second bottom plate 2 , and extends into the corresponding buffer groove 5, and the bottom ends of the two extrusion rods 25 are respectively connected to the two universal wheels 29, and a magnet rod 27 is installed inside the extrusion rod 25. The top and bottom ends of the magnet rod 27 in the first stable adjustment mechanism penetrate the inner wall of the extrusion rod 25 and are respectively connected to the corresponding extrusion plate 24 and the universal wheel 3. The top and bottom ends of the magnet rod 27 in the second stable adjustment mechanism penetrate the inner wall of the extrusion rod 25 and are respectively connected to the corresponding extrusion plate 24 and the universal wheel 29. An induction coil 26 is installed on the top wall of the buffer groove 5, and the extrusion rod 25 is located in the induction coil 26.

[0036] In the present invention, the mahjong table is normally detachably mounted on the two mounting plates 11. If the mahjong table is not needed, the locking portion in the telescopic rod 10 is opened so that the telescopic rod 10 can be freely extended and retracted, and the mahjong table is bent toward the buffer pad 8 until the mahjong table changes from a horizontal state to a vertical state. At this time, the lower half of the back of the mahjong table will contact the buffer pad 8 on the baffle 7. The buffer pad 8 can absorb the impact force when the back of the mahjong table collides with the baffle 7, thereby preventing the mahjong table from being scratched or damaged. In the process of bending the mahjong table, the telescopic rod 10 plays a buffering role. When the mahjong table generates a large rotational inertia during the rotation process due to its own weight, the telescopic rod 10 can effectively slow down the rotation speed, avoiding the impact damage to the mahjong table or related mechanical structures due to excessive rotation. At the same time, with the rotation of the mahjong table, under the linkage action of the connecting plate 14, the second bottom plate 2 will also be synchronously lifted, thereby realizing simple storage of the entire device, convenient operation, no complicated steps or additional tools are required, and its space utilization rate is effectively improved.

[0037] When the mahjong table needs to be used, the mahjong table is bent upward to lift the mahjong table (that is, the mahjong table is returned to the horizontal state from the vertical state). In the process of lifting the mahjong table, the telescopic rod 10 plays an auxiliary pushing role, thereby reducing the burden of manual operation and making the lifting process more labor-saving and stable. After the mahjong table returns to the horizontal state, the second bottom plate 2 also returns to the horizontal state, and the universal wheel 29 on it contacts the ground, and then the telescopic rod 10 is locked by the locking part. At this time, under the coordinated action of the telescopic rod 10, the connecting plate 14 and the reinforcing rod 12, a rigid supporting structure can be formed, which effectively suppresses the lateral and longitudinal shaking of the mahjong table caused by external force, effectively ensures the stability of the mahjong table, thereby ensuring the experience of the players when playing cards, and then pushes the whole device. Under the rolling of the universal wheel 1 3 and the universal wheel 2 29, the whole device moves to a suitable position, and then the universal wheel 1 3 and the universal wheel 2 29 are locked by controlling the self-locking part to complete the fixation of the position of the whole device.

[0038] The driving device 13 normally provides kinetic energy for the use of the mahjong table (when the mahjong table is in use, it is electrically connected to the driving device 13 through a conductive medium such as a connecting wire). When the stability of the mahjong table needs to be enhanced (for example, the entire device is moved to the ground where there is a risk of tipping over), the bolts on the two fixing rods 17 are removed, and the fixing rods 17 are pulled out from the slots and the fixing grooves on the slider 18. Then, under the action of gravity, the slider 18 will move down in the slide groove 16 and drive the fixing plate 15 to move down, so that the support plate and the driving device 13 on the support plate move down synchronously and compress the spring 9. At this time, when the spring 9 is Under the action of elasticity, a buffering effect can be provided for the driving device 13 on the support plate to prevent the driving device 13 from moving down too quickly. When the driving device 13 moves down to a position close to the top of the first base plate 1, the fixing rod 17 is reinserted into the fixing groove on the slot and the slider 18, and fixed to the support plate 6 by bolts. Since the driving device 13 is the heaviest object in the entire device due to its complex structure and numerous components, moving it downward can significantly lower the center of gravity of the entire device. As the center of gravity decreases, the entire device can become more stable, thereby effectively improving the stability of the mahjong table.

[0039] Under normal circumstances, the airbag 22 in the spherical frame is in a semi-expanded state. Although the airbag 22 in this state can squeeze the extrusion oil to a certain extent, part of the extrusion oil is still located in the spherical frame, and the extrusion plate 24 is located in the middle position of the oil chamber 23 (the four universal wheels 1 3 and the two universal wheels 2 29 are at the same height at this time). When the entire device is located due to the uneven ground and the mahjong table is tilted, first determine which side of the mahjong table is higher, then control the air extraction and discharge device 28 and open the electric control valve 20, and extract the gas in the airbag 22 corresponding to the higher side of the mahjong table through the air guide pipe 21 and the delivery pipe in turn. With the extraction of gas, the volume of the airbag 22 gradually shrinks, and its squeezing of the extrusion oil below is also weakened until it disappears. Therefore, the extrusion oil in the oil chamber 23 can flow back into the spherical frame.

[0040] If the position of the higher side of the mahjong table corresponds to the position of the universal wheel 3, at this time, since the universal wheel 3 is still in contact with the ground and bears part of the pressure, as the extruded oil flows back, the extrusion plate 24 also moves up in the oil chamber 23, thereby driving the extrusion rod 25 and the universal wheel 3 to rise as a whole, so that the height of the universal wheel 3 at the above side is gradually reduced. At the same time, by controlling the air extraction and discharge device 28 and opening the electric control valve 20 at the corresponding position, and repeating the above operation, the height of the universal wheel 3 in the middle is gradually reduced. This process makes the whole device gradually tend to be horizontal (that is, the higher side of the mahjong table is higher). The degree of flatness gradually decreases), thereby achieving the purpose of adjusting the flatness of the mahjong table, effectively avoiding the problem of negative impact on the player's gaming experience due to the tilt of the mahjong table, and ensuring the comfort and fluency of the player when playing cards. If the position of the higher side of the mahjong table corresponds to the position of the universal wheel 29, it is only necessary to adjust the height of the universal wheel 29 and the universal wheel 1 3 located in the middle in the above manner. In addition, if it is necessary to return the above-mentioned universal wheel 1 3 or universal wheel 29 to the original height, it is only necessary to inflate the corresponding air bag 22 through the air extraction and discharge equipment 28, the delivery pipe, the electric control valve 20 and the air guide pipe 21.

[0041] If the whole device vibrates due to the intense card playing of the players, the vibration sensors 4 on the first bottom plate 1 and the second bottom plate 2 capture the vibration forces in different directions in real time. When part of the whole device is subjected to upward force due to the vibration, the vibration sensor 4 is used to quickly locate the affected position, and the air pumping and exhausting device 28 is controlled to pump air toward the airbag 22 at the position subjected to the upward force, so that the squeezing plate 24 moves upward, and at the same time, current is passed through the induction coil 26 at the corresponding position (under normal circumstances, the induction coil 26 is in a power-off state). According to the principle of electromagnetic induction, after power is turned on, the induction coil 26 moves upward. The induction coil 26 will generate a magnetic field. At this time, the magnet rod 27 in the magnetic field will move upward due to the action of the magnetic field force, thereby causing the extrusion rod 25 to move upward, and then exerting an additional upward force on the extrusion plate 24. Under the combined action of air extraction and electromagnetic regulation, the universal wheel 1 3 or the universal wheel 2 29 can move upward rapidly in a very short time. Since the universal wheel 1 3 and the universal wheel 2 29 are located at the bottom of the device and in contact with the ground, a downward force is actually generated at the above position of the device at this time, thereby offsetting the upward movement tendency of the device caused by vibration.

[0042] Similarly, when a part of the entire device is subjected to a downward force due to vibration, the vibration sensor 4 is used to quickly locate the affected position, and the air bag 22 at the position subjected to the downward force is inflated by controlling the air extraction and discharge device 28, so that the extrusion plate 24 moves downward, and at the same time, a current is passed through the induction coil 26 at the corresponding position (the current flow direction at this time is opposite to the above current flow direction), so that the magnet rod 27 and the extrusion rod 25 move downward, and then an additional downward force is applied to the extrusion plate 24, so that the universal wheel 1 3 or the universal wheel 2 29 can move downward rapidly in a very short time. It is located at the bottom of the device and in contact with the ground. Therefore, an upward force is actually generated at the above position of the device at this time, thereby offsetting the downward movement tendency of the device caused by vibration. Through the synergistic effect of the above-mentioned vacuum, inflation and electromagnetic regulation, the entire device can respond quickly to vibrations in different directions, thereby effectively offsetting the movement tendency of the device caused by vibration (referring to quickly generating a force opposite to the vibration direction to offset the movement tendency of the device), making the mahjong table more stable, effectively avoiding the problem of mahjong tiles falling and generating additional noise due to the vibration of the mahjong table, and effectively ensuring the player's gaming experience.
