Technical Field
[0001] This utility model relates to the technical field of dice-rotating equipment, specifically to an automatic dice-throwing device. Background Technology
[0002] Dice games have a long history and are widely known in the field of game technology. Dice are cubes made of materials such as bone, wood, and plastic, with six faces marked with the numbers one, two, three, four, five, and six. Theoretically, fair dice have an equal probability of each face landing face up when rolled. However, the traditional way of rolling dice is to shake the dice in a dice cup by hand. This method involves high-frequency movements and a large swinging space, which can easily cause the dice to knock over surrounding objects. In addition, there are problems with the ability to roll the dice in a specific way to get the desired number.
[0003] To address the problems associated with hand-cranked dice cups, an electric method for rotating dice has been developed. Compared to hand-cranked dice cups, this method saves manpower and reduces human intervention. For example, existing patent CN201389329Y discloses a dice box with an operation panel where a finger activates the control buttons on the operation panel. The circuit board sends commands to the dice mechanism, causing the motor to run and the turntable to rotate, moving the dice in the dice chamber to achieve the purpose of spinning the dice. The technical problem is that rotating the base with a motor to flip the dice results in significant centrifugal force, causing severe wear on the surface of the base and the dice, leading to poor practicality. Utility Model Content
[0004] The purpose of this invention is to provide an automatic dice-throwing device.
[0005] This utility model is implemented by the following technical solution: an automatic dice throwing device, which includes a shell, a protective cover, a driving component, and a toggle block;
[0006] The top end face of the housing has an installation opening, and the protective cover is fixed to the inner wall of the top end of the housing. The top end of the protective cover extends through the installation opening to the outside of the housing. The bottom end of the protective cover has positioning grooves on both sides. Rotating columns are rotatably installed inside the positioning grooves. A placement platform is fixed between the two rotating columns. The top end of the placement platform extends into the inside of the protective cover, and there is a rotation gap between the placement platform and the inner wall of the protective cover.
[0007] A limiting component is fixed to the bottom of the side wall of the placement platform. The limiting component is positioned directly below one of the rotating columns. A guide groove matching the actuating block is provided in the middle of the limiting component. The driving component is fixed to the inner wall of the housing. The actuating block is fixed to the output shaft of the driving component. The actuating block is placed in the guide groove.
[0008] Furthermore, the protective cover is a transparent, spherical crown shape.
[0009] Furthermore, the placement platform is a transparent placement platform.
[0010] Furthermore, the protective cover includes a cover body and a support base. The support base is fixed to the bottom end face of the cover body and the positioning groove is provided on both sides of the support base.
[0011] Furthermore, a base is fixed to the inner wall of the bottom end of the housing, a camera is fixed to the top end face of the base, a fill light cover is provided on the outer cover of the camera, the bottom end of the fill light cover is snapped into the top end face of the base, and the fill light cover is placed below the placement platform.
[0012] Furthermore, it also includes a controller, the input of which is electrically connected to the camera, and the output of which is electrically connected to the mobile terminal and the speaker, and the speaker is fixedly connected to the outer wall of the housing.

[0016] The advantages of this invention are as follows: the driving component, limiting component, actuating block, and guide groove enable the placement platform to swing repeatedly, mimicking a hand-cranked dice cup, thus achieving controllable dice flipping. When the driving component is activated, it drives the actuating block to rotate repeatedly. During the rotation of the actuating block, it contacts the two side walls of the guide groove, causing the limiting component to swing. During the swing of the limiting component, the placement platform swings around the axis of the rotating column. The dice roll in multiple directions on the surface of the placement platform due to inertia. After the driving is completed, the dice stabilizes on the surface of the placement platform due to gravity, significantly reducing the wear of the dice and other contact surfaces caused by centrifugal force.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1-6 As shown, the automatic dice throwing device includes a housing 1, a protective cover 3, a driving component 10, and a toggle block 11.
[0027] The top end face of the housing 1 is provided with an installation port 2. The housing 1 provides protection for the internal components. A protective cover 3 is fixed to the inner wall of the top of the housing 1. The top of the protective cover 3 extends through the installation port 2 to the outside of the housing 1. Positioning grooves 4 are provided on both sides of the bottom end of the protective cover 3. Rotating columns 5 are rotatably provided inside the positioning grooves 4. A placement platform 6 is fixed between the two rotating columns 5. The top of the placement platform 6 extends into the inside of the protective cover 3. A rotation gap 7 is provided between the placement platform 6 and the inner wall of the protective cover 3. The rotation gap 7 allows the placement platform 6 to swing to a certain extent inside the protective cover 3 under the action of the oscillating block.
[0028] A limiting member 8 is fixed to the bottom of the side wall of the placement platform 6. The limiting member 8 is positioned directly below one of the rotating columns 5. A guide groove 9 matching the actuating block 11 is provided in the middle of the limiting member 8. A driving member 10 is fixed to the inner wall of the housing 1. The output shaft of the driving member 10 is fixed to the actuating block 11, which is placed in the guide groove 9. Through the action of the limiting member 8, the actuating block 11, and the guide groove 9, the placement platform 6 can swing repeatedly, mimicking a hand-cranked dice cup, making the dice flipping more controllable. When the driving member 10 is activated, it drives the actuating block 11 to rotate repeatedly. During the rotation of the actuating block 11, it interacts with both sides of the guide groove 9. The wall contact causes the limiting member 8 to swing. During the swing of the limiting member 8, the placing platform 6 swings around the axis of the rotating column 5. Due to inertia, the dice rolls in multiple directions on the surface of the placing platform 6. The transparency of the protective cover 3 allows observation of the throwing process. At the same time, the rotation gap 7 avoids direct contact and friction between the placing platform 6 and the protective cover 3. After the drive ends, the dice stabilizes on the surface of the placing platform 6 due to gravity. The protective cover 3 is a transparent spherical crown-shaped cover used to contain the dice and limit its range of motion, while allowing external observation of the internal state, which is convenient for judging the number. It significantly reduces the problem of wear on the dice and other contact surfaces caused by centrifugal force.
[0029] The protective cover 3 includes a cover body 3.1 and a support base 3.2. The bottom end face of the cover body 3.1 is fixed with a horizontally arranged support base 3.2. The support base 3.2 has positioning grooves 4 on both sides to accommodate the rotating column 5 for rotational support. With the action of the cover body 3.1 and the support base 3.2, it is convenient to replace the support base 3.2 or the protective cover 3 later.
[0030] The placement platform 6 is a transparent platform. The transparent platform 6, through its own light transmission characteristics and in combination with the transparent structure of the protective cover 3, allows the rolling process of the dice driven by the drive component 10 to be seen in its entirety by the camera 13. The bottom inner wall of the housing 1 is fixed with a base 12, and the top end face of the base 12 is fixed with a camera 13. The outer cover of the camera 13 is provided with a fill light cover 14, which can evenly distribute light to eliminate shooting shadows and effectively eliminate external light interference. The bottom end of the fill light cover 14 is snapped into the top end face of the base 12. The fill light cover 14 is placed below the placement platform 6, and the diameter of the fill light cover 14 is smaller than the diameter of the placement platform 6. The fill light cover 14 does not interfere with the swing of the placement platform 6.
[0031] It also includes a controller 15, whose input is electrically connected to the camera 13, and whose output is electrically connected to the mobile terminal 16 and the speaker 17. The speaker 17 is fixedly connected to the outer wall of the housing 1. The camera 13 can clearly capture the movement of the dice on the transparent platform 6. The image data captured by the camera 13 is transmitted to the mobile terminal 16 through the controller 15. Specifically, the controller 15 has a built-in Wi-Fi communication module to send the throwing result data to the mobile terminal 16, and at the same time play the result announcement audio in the speaker 17.
[0032] The top end face of the housing 1 has a slot 18, and a light board 19 is inserted into the slot 18. The light board 19 is a flat plate structure with light-emitting function, which is implemented by a circuit board with LED beads, and is used to provide light source during the dice rolling process.
[0033] The drive component 10 is a motor, and the top end face of the housing 1 is provided with a motor start / stop button to control the start and stop status of the motor.
[0034] The housing 1 has a power interface 20 fixed inside. The power interface 20 is electrically connected to the lamp board 19, the motor and the motor start / stop button 21. Specifically, it can be implemented by integrating a DC 5.5mm socket with the PCB board to centrally distribute power to the lamp board 19 and the motor.
[0035] The specific operation process of this embodiment is as follows:
[0036] When in use, the dice are placed on the placement platform 6. The placement platform 6 and the protective cover 3 restrict the space for throwing the dice.
[0037] Connect the power supply and start the drive unit 10. When the drive unit 10 is started, the drive unit 10 drives the toggle block 11 to rotate repeatedly. During the rotation of the toggle block 11, it contacts the two side walls of the guide groove 9 respectively, causing the limit member 8 to swing. During the swing of the limit member 8, the placement platform 6 swings around the axis of the rotating column 5.
[0038] The dice roll in multiple directions on the surface of the placement platform 6 due to inertia, mimicking a hand-cranked dice cup. The transparency of the protective cover 3 allows for on-site observation of the throwing process, while the rotation gap 7 prevents the placement platform 6 from directly contacting and rubbing against the protective cover 3.
[0039] After the drive ends, the dice stabilizes on the surface of the platform 6 due to gravity. The camera 13 can clearly capture the movement of the dice on the transparent platform 6. The image data collected by the camera 13 is wirelessly transmitted to the mobile terminal 16 via Wi-Fi, and the result announcement audio is played in the speaker 17 at the same time.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
