Description

Technical Field

[0001] The utility model relates to the field of mahjong machines, in particular to a mainframe of a mahjong machine. Background Art

[0002] There are now more and more different ways to play mahjong. To accommodate these different styles, mahjong machines now have multiple modes to meet the needs of users. For styles that use a large number of tiles, the push and raise mechanisms of the mahjong machine need to deliver more tiles to the table.

[0003] In order to use mahjong playing methods with more pile positions, the sizes of the stacking plate of the stacking mechanism, the pushing plate of the pushing mechanism, and the raising plate of the raising mechanism in the main body of the mahjong machine need to be further increased. The increase in the size of the above components further occupies space inside the main body.

[0004] The corners of the mahjong machine are equipped with hinges for opening and closing the panel. Part of the hinge is fixed to the panel, and the other part is fixed to the corner support of the mahjong machine. In order to flip the panel open and position it at a certain angle, the hinge needs to have a supporting function. For details, please refer to the hinge in the utility model patent with publication number CN212854602U and the name of the mahjong machine. When the cover of this hinge is open, the hinge plates close together to provide support and positioning force for the panel. As the panel is closed, the hinge plates in the hinge gradually separate and open. However, the separation and opening of the hinge plates intrude into the internal space of the main unit, causing interference between them and the internal components of the main unit.

[0025] After adopting the above technical solution, the utility model has the following beneficial effects.

[0026] 1. In the mainframe of the mahjong machine proposed by the present invention, when the panel is flipped open, the gravity of the panel is supported by the second support plate, and the two ends of the connector that positions the panel at the opening angle are respectively connected to the first support plate and the panel. The connector is used to resist and overcome the force that causes the panel to have a tendency to tip over at the opening angle. The force generated when the panel is in the flipped open state is shared by the first support plate and the connector, and the connector only bears a part of the force. Therefore, the connector can be made lighter and thinner, thereby reducing the space occupied by the connector, and further reducing the interference between the connector and the internal components of the mainframe of the mahjong machine.

[0027] 2. The connector is rotatably connected through multiple connecting units. When the panel is flipped open, the connector is tightened between the panel and the first support plate. When the panel is flipped closed, the connector is folded and stored in the frame. Since the force applied to the connector when tightening the panel is opposite to the folding direction of the connector, the connector will not actively fold when tightening the panel. The connector does not require additional fixation or support when tightening the panel, thereby simplifying the structure of the connector and helping to reduce the cost of the connector.

[0028] 3. By setting up two folding units, the structure of the connecting piece is made simpler, which helps to reduce the cost of the connecting piece. At the same time, since the first folding unit and the second folding unit are rigid, they will be fixed in the folded position and remain motionless when folded, avoiding the shaking of the connecting piece and collision with the internal components of the host when the host is subjected to external force. At the same time, the folding of the two reduces the occupied space, thereby further reducing or avoiding interference with the internal components of the host.

[0029] 4. Both the first folding unit and the second folding unit are sheet-like structures. This arrangement reduces the space inside the host occupied by the connector in the stored state. The connector takes up space from the inside of the host in the longitudinal direction. Since the internal components of the host are all placed horizontally, the space taken up by the connector in the longitudinal direction will not interfere with the internal components of the host, thereby reducing the interference between the connector and the internal components of the host.

[0030] 5. The straight-line distance between the rotation connection point of the first folding unit and the second folding unit and the first connection point is L3, and the straight-line distance between the rotation connection point of the first folding unit and the second folding unit and the second connection point is L4. Either L3 or L4 is smaller than the sum of the other and L2. Through the above setting, it is ensured that the four corners of the panel can be supported on the frame when the panel is flipped and closed, thereby improving the stability of the panel in the flipped and closed state.

[0031] 6. At least two connecting units are retractably connected, and another simple structure is used to realize that the connecting member deforms as the panel is turned over, which can also simplify the structure of the connecting member and help reduce the cost of the connecting member.

[0032] 7. By setting up two telescopic units, the telescopic structure of the connecting part is made simpler, which helps to reduce the cost of the connecting part. At the same time, since the telescopic direction of the two telescopic units is not always consistent with the flipping direction of the panel during the panel flipping process, the telescopic direction and the flipping direction of the panel have a certain angle, which makes the two telescopic units move with resistance. This part of the resistance helps to provide damping when the panel is flipped, thereby avoiding rapid falling when the panel is flipped, thereby improving the safety of the panel when flipping.

[0033] 8. The connecting piece is a flexible connecting unit. One end of the flexible connecting unit is connected to the panel to form a first connection point, and the other end of the flexible connecting unit is connected to the first support plate to form a second connection point. The flexible connecting unit is flexibly deformed as the panel flips. By using the flexible connecting unit to connect the panel and the first support frame, the structure of the connecting piece is simpler, and the cost of the connecting piece is further reduced.

[0034] 9. A connecting seat is set to increase the effective area between the connecting piece and the panel, thereby dispersing the acting force between the connecting piece and the panel, and preventing the panel from being damaged by excessive force when it is flipped open.

[0035] 10. A supporting portion is provided at one end of the connecting seat, and the function of the supporting portion for supporting the panel is combined with the connecting seat, thereby reducing parts, reducing assembly processes, and reducing costs.

[0036] 11. A hook is provided at one end of the support portion, and an inwardly bent flange is provided at the upper end of the second support plate. When the panel is flipped open, the hook stops at the flange to limit the panel from separating from the second support plate, thereby improving the safety of the panel during the flipping and opening process.

[0037] 12. The space inside the host is defined by corner supports and pull rods, which facilitates defining the installation area of ​​various components inside the host. At the same time, when the panel is flipped and closed, the pull rod can provide auxiliary support to the panel, thereby improving the stability of the panel in the closed state.

[0038] 13. Since the connectors in the aforementioned solution are thinner and lighter than those in the prior art, the reserved gap between the side panels of the frame and the card-pushing plate can be used to accommodate the connectors in the storage state, thereby further reducing the interference between the connectors and the internal components of the host. The host can adapt to mahjong games with more pile positions, and the outer dimensions of the host for multi-pile games do not need to be redesigned, reducing the corresponding costs.

[0039] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0061] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "clockwise", "counterclockwise" and the like to indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0062] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" or "several" means two or more, unless expressly limited otherwise.

[0063] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0064] like Figures 1 to 13As shown, the main body of the mahjong machine proposed in the embodiment of the present invention includes a base plate 100, a panel 300, and a card handling device disposed on the base plate 100. The card handling device includes a card shuffling mechanism and four horizontal push-pushing card lifting mechanisms 500 located at the bottom center. The panel 300 covers the top, and the panel 300 corresponds to a card entry for inserting mahjong tiles and a card lifting port for lifting mahjong tiles out. The specific working principle of the card handling device is well known to those skilled in the art and will not be described in detail here.

[0065] In this embodiment, a frame 200 is provided on the base plate 100. The frame 200 includes four corner supports 210, which are formed by connecting a first support plate 211 and a second support plate 212 at an angle. The four corner supports 210 are respectively supported between the base plate 100 and the four corners of the panel 300. The panel 300 is connected to two adjacent corner supports 210 so that the panel 300 can be flipped open and closed relative to the base plate 100. When the panel 300 is flipped open, one end of the panel 300 is supported by the second support plate 212 of the corner support 210. When the panel 300 is flipped closed, the four corners of the panel 300 are covered and supported by the four corner supports 210.

[0066] In order to prevent the opening and closing mechanism of the panel 300 from interfering with the internal components of the host when the panel 300 is closed, in this embodiment, the host further includes a connecting member 400. The connecting member 400 includes a first connecting point 401 connected to the panel 300 and a second connecting point 402 connected to the first support plate 211. The connecting member 400 can deform as the panel 300 is turned over so that the connecting member 400 has the following features:

[0067] As the panel 300 is flipped open to its unfolded state, the connector 400 provides a positioning force between the panel 300 and the first support plate 211 to maintain the panel 300 in its open state. The straight-line distance between the first connection point 401 and the second connection point 402 is L1; and

[0068] As the panel 300 is flipped and closed, the connector 400 is stored in the frame 200. The straight-line distance between the first connection point 401 and the second connection point 402 is L2. <L1。

[0069] The positioning force can be a pulling force or a supporting force.

[0070] In the prior art (e.g., referring to the hinge in the utility model patent with publication number CN212854602U, entitled "Mahjong Machine"), the hinge used for flipping and opening the panel 300 needs to withstand all forces generated by the panel 300 when the panel 300 is flipped open. However, in the present utility model, when the panel 300 is flipped open, the weight of the panel 300 is supported by the second support plate 212, while the ends of the connector 400, which positions the panel 300 at the open angle, are respectively connected to the first support plate 211 and the panel 300. The connector 400 is used to resist and overcome the force that would cause the panel 300 to tip over at the open angle. The force generated by the panel 300 in the flipped open state is shared by the first support plate 211 and the connector 400, and the connector 400 only bears a portion of the force. Therefore, the connector 400 can be made lighter and thinner, thereby reducing the space occupied by the connector 400 and further reducing the interference between the connector 400 and the internal components of the mahjong machine.

[0071] In this embodiment, the frame 200 further includes a tie rod 220 connecting two adjacent corner supports 210. The four corner supports 210 and the four tie rods 220 form a rectangular frame 200, and the four tie rods 220 define the four sides of the frame 200. The corner supports 210 and the tie rods 220 define the space inside the main unit, facilitating the definition of the installation areas for various components within the main unit. Furthermore, when the panel 300 is flipped closed, the tie rods 220 provide auxiliary support for the panel 300, improving its stability in the closed state.

[0072] In one embodiment, Figures 2 to 4 As shown, the four horizontal push-up card-lifting mechanisms 500 correspond to the four side panels of the frame 200 respectively. The horizontal push-up card-lifting mechanism 500 includes a card-pushing plate 501. The card-pushing plate 501 pushes horizontally from the side of the frame 200 toward the center of the frame 200. A gap 240 is reserved between the side of the frame 200 and the corresponding card-pushing plate 501 for accommodating the connector 400 in the storage state.

[0073] The pushing plate 501 is used to push the stacked mahjong tile piles. Due to the multi-pile mahjong gameplay, the increase in the pile positions of the stacked mahjong tile piles causes the length of the pushing plate 501 to increase accordingly, resulting in one side of the pushing plate 501 extending toward the corner support 210. The size of the mahjong tiles has not changed, and the width of the pushing mechanism has not changed, so the reserved gap 240 between the pushing plate 501 and the side of the frame 200 has not changed. Since the connecting member 400 in the aforementioned scheme is lighter and thinner than the prior art, the reserved gap 240 between the side panel of the frame 200 and the pushing plate 501 can be used to accommodate the connecting member 400 in the storage state, thereby further reducing the interference between the connecting member 400 and the internal components of the host. The host can adapt to mahjong gameplay with more pile positions, and the outer dimensions of the host for multi-pile gameplay do not need to be redesigned, reducing the corresponding cost.

[0074] In one embodiment, Figures 5 to 11 As shown, the connecting member 400 is explained. The connecting member 400 is formed by rotating and connecting at least two connecting units. In the unfolded state, at least two connecting units are unfolded along the flipping and opening direction of the panel 300, and the straight-line distance L between the first connection point 401 and the second connection point increases. In the retracted state, at least two connecting units are folded along the flipping and closing direction of the panel 300, and the straight-line distance L between the first connection point 401 and the second connection point 402 decreases.

[0075] When the panel 300 is flipped open, the connecting member 400 provides a pulling force between the panel 300 and the first support plate 211 , and the flipping opening angle of the panel 300 relative to the bottom plate 100 is greater than 90°.

[0076] There are at least two rotation connection points between at least two connection units, between a connection unit and the panel 300 , and between a connection unit and the first support plate 211 , so that the connection member 400 can be unfolded or folded as the panel 300 is turned over.

[0077] The connector 400 is rotatably connected through multiple connecting units. When the panel 300 is flipped open, the connector 400 is tightened between the panel 300 and the first support plate 211. When the panel 300 is flipped closed, the connector 400 is folded and stored in the frame 200. Since the force applied to the connector 400 when tightening the panel 300 is opposite to the folding direction of the connector 400, the connector 400 will not actively fold when tightening the panel 300. The connector 400 does not require additional fixation or support when tightening the panel 300, thereby simplifying the structure of the connector 400 and helping to reduce the cost of the connector 400.

[0078] like Figures 5 to 11As shown, in one embodiment, the connecting member 400 includes a first folding unit 410 and a second folding unit 420, one end of the first folding unit 410 is rotatably connected to one end of the second folding unit 420 so that the two can be folded and deformed, the other end of the first folding unit 410 is rotatably connected to the panel 300 to form a first connection point 401, and the other end of the second folding unit 420 is rotatably connected to the first support plate 211 to form a second connection point 402.

[0079] When the panel 300 is flipped open, the first folding unit 410 and the second folding unit 420 are stretched in a straight line between the panel 300 and the corner support 210. At this time, the straight-line distance between the end of the first folding unit 410 that is rotatably connected to the panel 300 and the end of the second folding unit 420 that is connected to the second support plate 212 is L1. When the panel 300 flips from the flip-open state to the flip-closed state, the first folding unit 410 and the second folding unit 420 are gradually folded, and the first connection point 401 approaches the second connection point 402. When the panel 300 is flipped closed, the first folding unit 410 and the second folding unit 420 are folded and stored in the frame 200. At this time, the straight-line distance between the end of the first folding unit 410 that is rotatably connected to the panel 300 and the end of the second folding unit 420 that is connected to the second support plate 212 is L2. L2 <L1。

[0080] Preferably, the corner support member 210 is provided with a hinge shaft 231 and a hinge seat 230. The hinge shaft 231 is disposed in the hinge seat 230, and the second folding unit 420 is rotatably connected to the hinge shaft 231 in the hinge seat 230. The side wall of one side of the hinge seat 230 and the first support plate 211 restrict the rotation of the second folding unit 420 in the hinge seat 230.

[0081] By setting up two folding units, the folding structure of the connecting member 400 is made simpler, which helps to reduce the cost of the connecting member 400. At the same time, since the first folding unit 410 and the second folding unit 420 are rigid, the two will be fixed in the folded position and remain motionless when folded, avoiding the connecting member 400 from shaking and colliding with the internal components of the host when the host is subjected to external force. At the same time, the folding of the two reduces the occupied space, thereby further reducing or avoiding interference with the internal components of the host.

[0082] In one embodiment, Figures 5 to 7 As shown, the first folding unit 410 and the second folding unit 420 are both sheet-like structures.

[0083] In this embodiment, the first folding unit 410 and the second folding unit 420 are sheet metal structures. The first folding unit 410 and the second folding unit 420 are stacked in the thickness direction and rotated to connect to reduce the thickness of the connecting member 400. The thickness direction of the connecting member 400 is configured to be approximately horizontal, so that the projection of the connecting member 400 on the base plate 100 is its cross-section in the thickness direction.

[0084] Such an arrangement reduces the space inside the host occupied by the connector 400 in the stored state. The connector 400 requires space from the inside of the host in the vertical direction. Since the internal components of the host are all placed horizontally, the space required by the connector 400 in the vertical direction will not interfere with the internal components of the host, thereby reducing the interference between the connector 400 and the internal components of the host.

[0085] In one embodiment, Figures 5 to 7 As shown, the straight-line distance between the rotation connection point of the first folding monomer 410 and the second folding monomer 420 and the first connection point 401 is L3, and the straight-line distance between the rotation connection point of the first folding monomer 410 and the second folding monomer 420 and the second connection point 402 is L4, and either L3 or L4 is smaller than the sum of the other and L2.

[0086] When the panel 300 is flipped and closed, a roughly triangular structure is formed between the rotational connection points of the first folding unit 410 and the second folding unit 420 and the first connection point 401 and the second connection point 402. In this embodiment, the first folding unit 410 is longer than the second folding unit 420. When the panel 300 is flipped and folded, the first connection point 401 moves closer to the second connection point 402. The corresponding length of L2 is smaller, so the length of L3 is greater than L2 and L4. L3 needs to be less than the sum of L2 and L4. If the above conditions are not met, it means that the panel 300 is restricted by the first folding unit 410 and the second folding unit 420 at a certain position during the flipping and closing process and cannot be further flipped. The flipped panel 300 cannot cover the frame 200. The first folding unit 410, the second folding unit 420 and the corner connector 210 together support the flipped and closed panel 300.

[0087] In some other embodiments, the length of the second folding unit 402 may be greater than the length of the first folding unit 401 .

[0088] Through the above arrangement, it is ensured that the four corners of the panel 300 can be supported on the frame 200 when the panel 300 is flipped and closed, thereby improving the stability of the panel 300 in the flipped and closed state.

[0089] In one embodiment, Figure 12 、 Figure 13As shown, the connector 400 is explained. The connector 400 is formed by a retractable connection of at least two connecting units. In the unfolded state, at least two connecting units are stretched along the flipping and opening direction of the panel 300. In the retracted state, at least two connecting units are contracted along the flipping and closing direction of the panel 300.

[0090] At least two connecting units may be damped telescopic devices, such as dampers. The at least two connecting units may be damped telescopic devices that can provide support when the panel 300 is flipped open at an angle less than or equal to 90 degrees, and can provide tension when the panel 300 is flipped open at an angle greater than 90 degrees.

[0091] At least two connecting units can also be freely retractable and have a limit at the extreme position, such as a sleeved telescopic tube. At least two connecting units can be freely retractable to provide tension when the panel 300 is flipped open at an angle greater than 90 degrees.

[0092] The at least two connecting units are retractably connected, and another simple structure is used to realize that the connecting member 400 is deformed as the panel 300 is flipped. This can also simplify the structure of the connecting member 400 and help reduce the cost of the connecting member 400.

[0093] like Figure 12 、 Figure 13 As shown, in one embodiment, the connecting member 400 includes a first telescopic unit 430 and a second telescopic unit 440, one of the first telescopic unit 430 and the second telescopic unit 440 can be telescoped relative to the other, the first telescopic unit 430 rotates to connect the panel 300 to form a first connection point 401, and the second telescopic unit 440 rotates to connect the first support plate 211 to form a second connection point 402.

[0094] Preferably, in this embodiment, the first telescopic unit 430 is telescopic relative to the second telescopic unit 440. When the panel 300 is flipped and closed, one end of the first telescopic unit 430 is retracted into the second telescopic unit 440. When the panel 300 is flipped and opened, the first telescopic unit 430 is stretched out from the second telescopic unit 440.

[0095] It is understandable that the first telescopic unit 430 and the second telescopic unit 440 can be telescopic tubes that are connected to each other. The second telescopic unit 440 can also be a seat of the damper, and the first telescopic unit is a rod extending from the seat.

[0096] In some other embodiments, one end of the second telescopic unit 440 may be retracted into the first telescopic unit 430 so that the second telescopic unit 440 can be retracted relative to the first telescopic unit 430 .

[0097] By setting up two telescopic units, the telescopic structure of the connecting member 400 is made simpler, which helps to reduce the cost of the connecting member 400. At the same time, since the telescopic direction of the two telescopic units is not always consistent with the flipping direction of the panel 300 during the flipping process of the panel 300, the telescopic direction and the flipping direction of the panel 300 have a certain angle, so that the two telescopic units have resistance movement. This part of the resistance helps to provide damping when the panel 300 is flipped, thereby avoiding rapid falling when the panel 300 is flipped, thereby improving the safety of the panel 300 when it is flipped.

[0098] In one embodiment, the connecting member 400 is described as a flexible connecting unit, one end of the flexible connecting unit is connected to the panel 300 to form a first connecting point 401, and the other end of the flexible connecting unit is connected to the first support plate 211 to form a second connecting point 402. The flexible connecting unit is flexibly deformed as the panel 300 is flipped.

[0099] When the panel 300 is flipped open, the flexible connector is stretched between the panel 300 and the first support frame 211, providing tension between them. The panel 300 is opened at an angle greater than 90° relative to the base plate 100. When the panel 300 is flipped closed, the flexible connector deforms to be stored within the frame 210. The ends of the flexible connector can be fixedly connected to the panel 300 and the first support frame 211, or they can be rotatably connected.

[0100] The flexible connecting unit can be a drawstring, such as a braided fabric rope or a steel wire rope. The flexible connecting unit can also be a chain formed by connecting multiple ring units or link units. During the flipping and closing of the panel 300, the flexible connecting unit flexibly bends and deforms, causing the first connection point 401 to move closer to the second connection point 402.

[0101] By adopting a flexible connection unit to connect the panel 300 and the first support frame 211 , the structure of the connection member 400 is simplified, and the cost of the connection member 400 is further reduced.

[0102] In one embodiment, Figures 2 to 7 As shown, the main body of the mahjong machine also includes a connector 600, which is mounted on the panel 300. The connector 400 is connected to the connector 600, forming a first connection point 401. The connector 600 includes a connector body 601 and a connecting plate 602 extending from one end of the connector body 601 away from the panel 300. The connector 400 is connected to the connecting plate 602. The connector body 601 is sheet-shaped and fixed to the back of the panel 300.

[0103] Such a setting avoids the connection between the connecting member 400 and the panel 300, which would cause the panel 300 to be easily damaged due to the force between the connecting member 400 and the panel 300. By setting the connecting seat 600, the effective area between the connecting member 400 and the panel 300 is increased, thereby dispersing the force between the connecting member 400 and the panel 300, and avoiding the panel 300 from being damaged by excessive force when it is flipped open.

[0104] In one embodiment, Figures 2 to 7 As shown, a support portion 610 is provided at one end of the connection base 600. When the panel 300 is flipped open, the support plate rests on the second support plate 212. The support portion 610 extends from the lower end of the connection base 600 in a direction away from the panel 300. By providing the support portion 610 at one end of the connection base 600, the function of the support portion 610, which supports the panel 300, is combined with the connection base 600, thereby reducing the number of parts, the assembly process, and costs.

[0105] In one embodiment, Figures 2 to 8 As shown, a hook 612 is provided at one end of the support portion 610, and an inwardly bent flange 2121 is provided at the upper end of the second support plate 212. When the panel 300 is flipped open, the hook 612 stops at the flange 2121 to prevent the panel 300 from separating from the second support plate 212. The support portion 610 includes a support portion body 611 and a hook 612. The support plate body is sheet-shaped, and the hook 612 is formed by extending from one end of the support portion body 611 in a direction away from the panel 300. When the panel 300 is flipped open, the support portion body 611 is supported on the second support plate 212, and the hook 612 can be hooked onto the flange 2121 to prevent the panel 300 from separating from the second support plate 212 when flipped open, thereby improving the safety of the panel 300 during the flipping and opening process.

Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the above specific embodiments.
