Description

Technical Field

[0001] The utility model relates to the technical field of gaming machine devices, and particularly refers to an electric dice with a controllable display surface. Background Art

[0002] In gaming machines, in order to achieve the effect of pattern transformation and convey different information to players, flat devices such as display screens or turntables are usually used to display pattern transformation. However, this approach has certain limitations in terms of ornamental value and interestingness.

[0003] As a common gaming prop, a dice is usually a six-sided cube, with different patterns on each face, used to convey different information and instructions to players. By rotating to change the orientation of the dice, players can make decisions on game strategies based on the patterns of a specific orientation.

[0004] However, if the dice is manually thrown by players, the patterns shown on the dice are uncontrollable, and the dice is also prone to being lost. Therefore, it is very necessary to design a device that can control the rotation of the dice and display the patterns of the six faces of the dice to players. Through this device, players can better observe different faces of the dice during the game, increasing the interestingness and playability of the game. Content of the Utility Model

[0005] (1) Technical Problem

[0006] The utility model provides an electric dice with a controllable display surface, aiming to solve the problems that the patterns shown when a traditional dice is thrown are uncontrollable and the dice is prone to being lost.

[0007] (2) Technical Content

[0008] To solve the above technical problem, the technical solution of the utility model is: an electric dice with a controllable display surface, including a support plate, a DC motor is fixedly arranged on the rear side surface of the support plate, one end of the driving shaft of the DC motor extending into the front side of the support plate is fixedly provided with a basket, a dice is rotatably arranged inside the basket, an L-shaped bracket is fixedly arranged on the outer side surface of the basket, a stepping motor is fixedly arranged at the upper end of the L-shaped bracket, the driving shaft of the stepping motor extends into the inside of the basket and is drivingly connected with the dice, a transverse limiting mechanism is arranged in a matching manner between the L-shaped bracket and the driving shaft of the stepping motor, and a longitudinal limiting mechanism is arranged in a matching manner between the support plate and the L-shaped bracket.

[0009] Further, the transverse limiting mechanism includes an in-situ optoelectronic switch fixedly arranged at the upper end of the L-shaped bracket, and further includes a first light-blocking plate fixedly arranged on the driving shaft of the stepping motor, and the first light-blocking plate is adapted to the in-situ optoelectronic switch.

[0010] Furthermore, the longitudinal limiting mechanism includes an upper photoelectric door and a lower photoelectric door fixed on the bracket plate and located at the upper and lower sides of the basket respectively, and also includes a second light-blocking plate fixed on the side of the L-shaped bracket, the second light-blocking plate rotates with the L-shaped bracket and is compatible with the upper photoelectric door and the lower photoelectric door.

[0011] Furthermore, a semicircular ring-shaped limiting groove is provided on the front of the bracket plate, and a limiting column is fixedly provided on the side of the L-shaped bracket, and the limiting column extends into the limiting groove and cooperates with the limiting groove gap.

[0012] Furthermore, after the DC motor is powered on, the longitudinal limit mechanism controls the alternating forward and reverse rotations. When the second light baffle rotates to the upper photoelectric gate, the DC motor rotates in reverse, and when the second light baffle rotates to the lower photoelectric gate, the DC motor rotates in the forward direction.

[0013] (III) Technical Effects

[0014] Compared with the prior art, the utility model has the following advantages: the DC motor drives the basket to rotate, and the stepper motor drives the dice to rotate, so that the dice can show different patterns on its six sides to the player. This design allows players to observe the different sides of the dice more intuitively, increasing the playability and fun of the game. Driven by the DC motor and the stepper motor, the dice can rotate quickly and show different patterns when they stop, without the need to throw the dice manually. This can avoid uncontrollable factors caused by manual throwing, while reducing the possibility of losing the dice, and improving the convenience and sustainability of the game. The DC motor controls the rotation of the basket, and the stepper motor drives the rotation of the dice. Through the action of the longitudinal limit mechanism and the lateral limit mechanism, the number of rotations of the dice can be controlled, and the rotation of the dice can be precisely controlled by controlling the up and down position and the rotation angle of the stepper motor. This ensures that a specific pattern is displayed when the dice stops, conveys accurate information and instructions to the players, and improves the operability and experience of the game.

[0022] The following further describes the present utility model in detail with reference to the drawings.

[0023] Combined with Fig. Figure 1 to Fig. Figure 4 , an electric dice with controllable display surface, comprising a bracket plate 1, a DC motor 2 is fixedly provided on the rear side surface of the bracket plate 1, one end of the driving shaft of the DC motor 2 extending into the front side of the bracket plate 1 is fixedly provided with a basket 3, a dice 4 is rotatably provided inside the basket 3, an L-shaped bracket 5 is fixedly provided on the outer side surface of the basket 3, a stepper motor 6 is fixedly provided at the upper end of the L-shaped bracket 5, the driving shaft of the stepper motor 6 extends into the inside of the basket 3 and is drivingly connected to the dice 4, a lateral limiting mechanism is arranged in a matching manner between the L-shaped bracket 5 and the driving shaft of the stepper motor 6, a longitudinal limiting mechanism is arranged in a matching manner between the bracket plate 1 and the L-shaped bracket 5, a semi-circular ring-shaped limit groove 12 is provided on the front surface of the bracket plate 1, a limit post 13 is fixedly provided on the side surface of the L-shaped bracket 5, the limit post 13 extends into the limit groove 12 and is in clearance fit with the limit groove 12, the limit groove 12 limits the rotation range of the L-shaped bracket 5, and the limit post 13 slides in the limit groove 12 to prevent the L-shaped bracket 5 from rotating excessively.

[0024] In this embodiment, the lateral limiting mechanism includes an in-situ photoelectric gate 7 fixedly arranged at the upper end of the L-shaped bracket 5, and further includes a first light-shielding plate 8 fixedly arranged on the driving shaft of the stepping motor 6, and the first light-shielding plate 8 is adapted to the in-situ photoelectric gate 7.

[0025] In this embodiment, the longitudinal limiting mechanism includes an upper photoelectric gate 9 and a lower photoelectric gate 10 which are fixedly arranged on the support plate 1 and are respectively located on the upper and lower sides of the basket 3, and further includes a second light-shielding plate 11 fixedly arranged on the side surface of the L-shaped bracket 5. The second light-shielding plate 11 rotates following the L-shaped bracket 5 and is adapted to both the upper photoelectric gate 9 and the lower photoelectric gate 10. After the DC motor 2 is powered on, its forward and reverse rotations are alternately controlled by the longitudinal limiting mechanism. When the second light-shielding plate 11 rotates to the upper photoelectric gate 9, the DC motor 2 rotates in reverse. When the second light-shielding plate 11 rotates to the lower photoelectric gate 10, the DC motor 2 rotates forward.

[0026] Specific implementation manner of the present utility model: Before the present utility model is used, an external power supply is first connected. The support plate 1 is fixed to the gaming device by bolts. The DC motor 2 is started. The initial position of the second light-shielding plate 11 is at the upper photoelectric gate 9. At this time, the DC motor 2 rotates in reverse, driving the basket 3 and the L-shaped bracket 5 to rotate. Until the second light-shielding plate 11 rotates to the lower photoelectric gate 10, the DC motor 2 rotates forward, driving the basket 3 and the L-shaped bracket 5 to rotate in the reverse direction. When the second light-shielding plate 11 rotates to the upper photoelectric gate 9 again, the DC motor 2 rotates in reverse again, and so on, thereby realizing the reciprocating rotation of the basket 3 and the L-shaped bracket 5. At the same time, the stepping motor 6 is started to drive the dice 4 to rotate. When the first light-shielding plate 8 is located at the in-situ photoelectric gate 7, it is recorded as the initial angle. At this time, the rotation angle of the stepping motor 6 is 0°. As the rotation angle of the stepping motor 6 is different, the dice 4 will display different pattern faces. The rotation angles of the stepping motor 6 have the following values: 0°, 60°, 120°, 180°, 240°, 300°. The corresponding display faces of the dice 4 are the A face, the D face, the B face, the F face, the C face, and the E face respectively. When the DC motor 2 stops, the second light-shielding plate 11 stays at the upper photoelectric gate 9 or the lower photoelectric gate 10. With the above design, the display face of the dice 4 can be controlled by controlling the staying position of the second light-shielding plate 11 and the rotation angle of the stepping motor 6. The relationship between each display face of the dice, the upper photoelectric gate, the lower photoelectric gate, the in-situ photoelectric gate, and the running angle of the stepping motor is shown in detail in the following table.

[0027] Dice face orientation Upper photogate status Lower photogate status Home photogate status Stepper motor running angle Side A ON ON 0° Side B ON 120° Side C ON 240° Side D ON 60° Side E ON 300° Side F ON 180°

[0028] When the first light shield 8 is located between the in-situ photoelectric gates 7, that is, when the rotation angle of the stepper motor 6 is 0°, the in-situ photoelectric gate is in the ON state. At the same time, the DC motor 2 controls the second light shield 11 to be between the upper photoelectric gate 9, and the upper photoelectric gate 9 is in the ON state. At this time, the display surface of the dice 4 is the A surface; when the stepper motor 6 is started and drives the dice 4 to rotate by 120°, the display surface of the dice is the B surface; when the stepper motor 6 is started and drives the dice to rotate by 240°, the display surface of the dice is the C surface; when the DC motor 2 is started to rotate the second light shield 11 to between the lower photoelectric gate 10, and the lower photoelectric gate 10 is in the ON state. At this time, when the stepper motor 6 is started and drives the dice 4 to rotate by 60°, the display surface of the dice is the D surface; when the running angle of the stepper motor 6 is 300°, the display surface of the dice is the E surface; when the running angle of the stepper motor 6 is 180°, the display surface of the dice is the F surface.

[0029] The above describes the present invention and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the creation of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
