Description

One mainstream method involves attaching a magnet to the dart head and laying a metal grid on the game screen, using magnetic force to attract the darts to the grid. However, the drawback of this existing technology is that after the darts are attracted, the player must manually walk to the screen each time and remove the darts from the metal grid to proceed to the next round. This process is cumbersome, disrupts the game flow, and causes inconvenience for players. Summary of the Invention

[0023] The technical solution of this application will be described in detail below with reference to specific embodiments.

[0024] Please see Figure 1A dart 100 release assembly includes a front panel 1, a push plate 2, a limiting plate 3, multiple top posts 4, multiple guide posts 5, and a spring 6. The push plate 2 is located between the front panel 1 and the limiting plate 3. The spring 6 is sleeved on the top post 4, with one end of the spring 6 abutting against the inner side of the front panel 1 and the other end of the spring 6 abutting against the side of the push plate 2 facing the front panel 1. The top post 4 is connected to the push plate 2, and one end of the top post 4 has a radially protruding abutment seat 41. The front panel 1 has multiple first through holes 11, through which the top post 4 passes, and the abutment seat 41 is disposed opposite to the outer side of the front panel 1. The push plate 2 has multiple second through holes 21, through which the guide post 5 passes. The guide post 5 is connected to the limiting plate 3, and one end of the guide post 5 is connected to the front panel 1. It is a linear bearing rod; the front panel 1 and the limiting plate 3 are connected by the guide post 5 to form a stable structure. The magnetic metal ring 13 is fixed around the movable hole on the front panel 1. The push plate 2 moves linearly on the guide post 5. In the adsorption state, after the dart 100 with N52 magnet flies to the front panel 1, it will be attracted to the magnetic metal ring 13 behind the front panel 1. In the ejection state, the force is applied to the push rod 7, so that the push plate 2 connected to the push rod 7 moves along the guide post 5 towards the front panel 1. At this time, the top post 4 is also pushed out, thus pushing the dart 100 attached to the front panel 1 off. In the retraction state, when the force from behind is quickly retracted, the top post 4 rebounds very quickly due to the force of the spring 6, thereby achieving rapid start and release. The push plate 2 is positioned between the front panel 1 and the limiting plate 3. Multiple top posts 4 are connected to one side of the push plate 2. By applying a force toward the front panel 1 to the push plate 2, one end of the top post 4 can be pushed out of the first through hole 11, thereby pushing out the dart 100 adsorbed on the front panel 1 and detaching it. After the force applied toward the front panel 1 to the push plate 2 is stopped, the spring 6 pushes the push plate 2 back to its original position, thereby resetting the top post 4.

[0025] In some embodiments, a push rod 7 is also included. At least one third through hole 31 is provided on the surface of the limiting plate 3. The push rod 7 passes through the third through hole 31, and one end of the push rod 7 is connected to the push plate 2. By applying a force to the push rod 7 toward the front panel 1, the push rod 7 can push the push plate 2 closer to the front panel 1.

[0026] In some embodiments, a plurality of connecting posts 22 are provided on the side of the push plate 2 near the limiting plate 3, and a reinforcing member 23 is provided between adjacent connecting posts 22. The reinforcing member 23 can prevent the connecting posts 22 from shaking and improve the service life of the connecting posts 22. One end of the connecting post 22 is connected to a positioning block 24. The side of the positioning member can abut against the inner side of the limiting plate 3, thereby limiting the distance between the push plate 2 and the limiting plate 3. A limiting member 25 is provided on one side of the positioning block 24, and one end of the push rod 7 is connected to the limiting member 25. A plurality of reinforcing ribs 251 are provided on the outer side of the limiting member 25. The reinforcing ribs 251 can increase the connection area between the limiting member 25 and the positioning block 24 and improve the stability of the limiting member 25 on the positioning block 24. One end of the reinforcing rib 251 is connected to the positioning block 24.

[0027] In some embodiments, a plurality of fixing rings 12 are provided on the side of the front panel 1 near the push plate 2. The fixing rings 12 surround the outer periphery of the first through hole 11, and a movable hole is formed in the middle of the fixing ring 12. The top post 4 passes through the movable hole and the first through hole 11 in sequence. A magnetic metal ring 13 is sleeved on the fixing ring 12. The magnetic metal ring 13 can be attracted by the magnet 101 at the front end of the dart 100, thereby fixing the dart 100 to the front panel 1. The magnetic metal ring 13 can be a hollow carbon steel cylinder. The push plate 2 A fixing member 26 is provided on the surface, and the top post 4 is connected to the fixing member 26; one end of the spring 6 abuts against the fixing ring 12, and the other end of the spring 6 abuts against the fixing member 26; a recessed part 14 is provided on the side of the front panel 1 away from the push plate 2, and the recessed part 14 is provided around the first through hole 11; the side of the abutment 41 is provided opposite to the surface of the recessed part 14. By providing the recessed part 14, the abutment 41 can be inserted into the recessed part 14, thereby keeping the front panel 1 flat and making it easy for the dart 100 to be attached to the front panel 1.

[0028] In some embodiments, a first positioning member 32 is provided on the outer side of the limiting plate 3, and a second positioning member 33 is connected to one end of the first positioning member 32. The second positioning member 33 is arranged along the movement direction of the top column 4. The first positioning member 32 and the second positioning member 33 are arranged perpendicular to each other. The first positioning member 32 and the second positioning member 33 are respectively used to connect with external devices, so that users can adjust the position of the limiting plate 3 in the horizontal and vertical directions.

[0029] In some embodiments, a plurality of first through holes 11 are arranged in an array on the front panel 1, which facilitates the top post 4 to push the dart 100 out of the front panel 1.

[0030] In some embodiments, the push plate 2 has at least one through hole 27 on its side, and the side wall of the through hole 27 has a hook 271 protruding outward. The hook 271 can be connected to an external device, and the external device can hook the hook 271 when no command to release the dart 100 is triggered, so as to prevent the top column 4 from accidentally pushing out the dart 100.

[0031] This application discloses a method for detaching a dart 100, including the dart 100 detachment components disclosed in the above embodiments, and the method includes: S1. The blocking signal generated when the dart 100 penetrates the infrared light grid is collected in real time through the infrared detection frame 8. The blocking signal includes the planar coordinate signal of the dart 100 hitting the front panel 1 and the target hit time information. S2. Calculate the dwell time of dart 100 on the front panel 1 based on the target hit time information, and compare the dwell time with the preset dwell time threshold. S3. When the dwell time exceeds the dwell time threshold, drive the top column 4 to push the dart 100 out of the front panel 1.

[0032] In some embodiments, in step S2, the adjacent distance between adjacent darts 100 is calculated based on the planar coordinate signal, and the adjacent distance is compared with a preset dwell distance threshold. If the adjacent distance is less than the dwell distance threshold, the top post 4 is driven to push the darts 100 out of the front panel 1. The total number of darts 100 on the front panel 1 is counted in real time. When the total number of darts 100 is greater than the preset maximum capacity threshold, the top post 4 is driven to push the darts 100 out of the front panel 1.

[0033] This application discloses a dart 100 detachment system, including the dart 100 detachment components disclosed in the above embodiments, and the system further includes: An infrared detection frame 8 is installed on the periphery of the front panel 1 to form an infrared light grid in front of the front panel 1. It detects the blocking signal generated when the dart 100 penetrates the infrared light grid in real time. The blocking signal includes the planar coordinate signal of the dart 100 hitting the front panel 1 and the moment of impact. The infrared detection frame 8 includes a first light grid assembly and a second light grid assembly. The first light grid assembly includes a first infrared emitting array and a first infrared receiving array. The first infrared emitting array is located on the first outer side of the front panel 1, and the first infrared receiving array is located on the second outer side of the front panel 1, with the first infrared emitting array and the first infrared receiving array positioned opposite each other. The first infrared emitting array and the first infrared receiving array form multiple infrared rays parallel to the X-direction to detect the position of the dart 100 in the Y-direction. The second light grid assembly includes a second infrared emitting array and a second infrared receiving array. The second infrared emitting array is located on the first outer side of the front panel 1, and the first infrared receiving array is located on the second outer side of the front panel 1. The second infrared emitting array is positioned on the second outer side of the front panel 1, with the first infrared emitting array positioned on the second outer side of the front panel 1, and the first infrared receiving array is positioned opposite each other. The first infrared emitting array and the first infrared receiving array form multiple infrared rays parallel to the X-direction to detect the position of the dart 100 in the Y-direction. The second light grid assembly includes a second infrared emitting array and a second infrared receiving array. The second infrared emitting array is positioned on the second outer side of the front panel 1, and the first infrared receiving array is positioned on the second outer side of the front panel 1, with the first infrared emitting array positioned on the second outer side of the front panel 1, and the first infrared receiving array is positioned on the second outer side of the front panel 1, and the first infrared receiving array is positioned on the second outer side of the front panel 1, and the first infrared receiving array is positioned The second infrared receiving array is positioned on the third outer side of the front panel 1, and the second infrared emitting array and the second infrared receiving array are positioned opposite each other. The second infrared emitting array and the second infrared receiving array form multiple infrared rays parallel to the Y direction, which are used to detect the position of the dart 100 in the X direction. The X direction and the Y direction are perpendicular to each other, and the X direction can be horizontal and the Y direction can be vertical. The first optical mesh assembly and the second optical mesh assembly are staggered by a certain distance (e.g., 5mm) in the flight direction of the dart 100, or use different infrared carrier frequencies (e.g., 38kHz and 56kHz) so that the microcontroller unit 9 can distinguish between the two sets of signals. When the dart 100 passes through the two optical meshes in sequence, the microcontroller unit 9 records the numbers of the blocked horizontal and vertical rays respectively, and combines them to obtain the precise planar coordinates (X, Y) of the dart 100. The microcontroller unit 9 (MCU) is electrically connected to the infrared detection frame 8. It is used to receive the blocking signal and determine whether the preset release trigger condition is met based on the blocking signal. If the condition is met, the release trigger signal of the dart 100 is generated. The telescopic assembly 10 has its control terminal electrically connected to the microcontroller unit 9 and its output terminal connected to the top column 4. It is used to drive the top column 4 to push the dart 100 out of the front panel 1 according to the dart 100 release trigger signal. The telescopic assembly 10 can be a telescopic cylinder or a telescopic motor. The transmission component 200 is electrically connected to the microcontroller unit 9. The transmission component 200 is located below the infrared detection frame 8 and is used to transport the dart 100 pushed out from the front panel 1 and to transport the dart 100 to the user side. The transmission component 200 can be a conveyor belt.

[0034] In the system of the present invention, a magnet 101 is provided at one end of the dart 100. When the user throws the dart 100 at the front panel 1, the magnet 101 will attract the magnetic metal ring 13 located on the inner side of the front panel 1, so that the dart 100 is fixed on the front panel 1. After the infrared detection frame 8 detects the dart 100, it sends the real-time coordinate information and the hit time information of the dart 100 to the microcontroller 9. The microcontroller 9 compares the real-time coordinate information and hit time information of multiple darts 100 with the preset judgment threshold. If it is determined that the dart 100 needs to be removed from the front panel 1, a trigger signal is sent to the telescopic component 10. The telescopic component 10 drives the top column 4 to push the dart 100 out of the front panel 1. After the dart 100 is removed from the front panel 1, it falls onto the conveying component 200 below. The conveying component 200 delivers the dart 100 to the player's hand, thereby realizing the automation of dart 100 retrieval.

[0035] Currently, most darts game machines use a fixed target, which is insufficient for advanced game design needs, especially for game display and more complex functions. Therefore, this invention designs a prototype darts machine that uses a pin to detach the dart head from the target (front panel 1) to address these shortcomings. Existing technology suffers from the drawback that most darts machines on the market use a magnet 101 on the dart head to attract a metal mesh on the screen. However, this requires players to manually remove the dart before starting the next round, which is inconvenient. Furthermore, the metal mesh on the screen results in poor display quality and a bad viewing experience. Therefore, the purpose of this invention is to address these shortcomings. The purpose is to achieve automatic retrieval of the dart 100, resulting in a clearer game screen and increased difficulty and challenge. This is achieved by replacing the metal agglutinator with individual iron rings arranged in an array behind the front panel 1, and then projecting an image, or by replacing the top post 4 with a translucent material and adding RGB LEDs. The dart 100 is then propelled a preset distance by the pin, detaching from the target and transported to the player via a conveyor belt, thus automating the dart retrieval process. The push-out of the top post 4 and its automatic retrieval by the spring 6 make the entire process fast and precise, allowing users to quickly start the next game. Furthermore, it provides a more refined and visually richer gaming experience.
