Technical Field
[0001] This utility model relates to the field of table football technology, and in particular to an intelligent table football automatic ball-serving device. Background Technology
[0002] Table football, also known as foosball or foosball, is a popular indoor sports and entertainment game suitable for use in homes, offices, and public places. It allows people to enjoy playing football on a table by scaling down a real football match. Table football typically consists of a rectangular game table with control levers on both sides. Players can rotate and push these levers to control miniature player figures, passing, shooting, and other actions to score goals against the opponent.
[0003] Currently, most table football equipment on the market uses a manual ball-throwing method, where players or referees manually place the ball into the playing area. This method has obvious drawbacks: on the one hand, improper human operation can easily lead to inconsistencies in the throwing position, angle, or force, affecting the rhythm and fairness of the game; on the other hand, it also leaves room for human intervention in the game's outcome, resulting in biased behavior and undermining the fairness and competitiveness of the competition.
[0004] Therefore, it is necessary to design an intelligent automatic ball-serving device for table football to solve the above-mentioned technical problems. Utility Model Content
[0005] In order to overcome the shortcomings of current table football, which mostly uses manual ball throwing, and is prone to affecting the consistency of throwing due to improper human operation, thus disrupting the fairness and rhythm of the game, and even causing biased behavior, this utility model provides an intelligent automatic ball throwing device for table football.
[0006] The technical implementation scheme of this utility model is as follows: an intelligent table football automatic ball-launching device, including a mounting base, a ball guide plate, a return ball guide plate, and a ball box. The ball guide plate is fixedly connected to the top of the mounting base. A ball inlet is opened at the rear of the ball guide plate, and a ball outlet is opened at the top of the ball guide plate. Return ball guide plates are symmetrically distributed and fixedly connected to both sides of the front of the ball guide plate. Return ball inlets are opened at the front of the ball guide plate. A ball box is connected and communicates with one side of each of the two return ball guide plates. The device also includes a ball-launching switch, a vertical plate, a servo motor, a connecting rod, a crank, a striking rod, a power storage spring, a fixing block, a wedge block, and a compression spring. A ball-launching switch is fixedly connected to the top of the mounting plate. A vertical plate is fixedly connected to the right side of the mounting plate. A servo motor is fixedly connected to the right side of the vertical plate. The output shaft of the servo motor passes through the vertical plate and is fixedly connected to a connecting rod. A crank is rotatably connected to the left side of the vertical plate. A groove is opened on the crank. One end of the connecting rod slides in the groove. A hitting stick is slidably connected inside the ball guide plate. A power storage spring is connected between the hitting stick and the ball guide plate. A fixing block is fixedly connected to the front of the hitting stick. A wedge block is slidably connected inside the fixing block. The wedge block abuts against one end of the crank. A symmetrically distributed compression spring is connected between the wedge block and the fixing block.
[0007] Optionally, the ball guide plate has an L-shaped structure, and both return ball guide plates have an inclined structure.
[0008] Optionally, the gap between the two return ball groove plates is equal to the side length of the return ball opening.
[0009] Optionally, it also includes a fixed shell, a baffle, and a first torsion spring. The fixed shell is fixedly connected to the front of the ball guide plate, and the baffle is rotatably connected inside the fixed shell. The baffle is located inside the ball guide plate, and the first torsion springs are symmetrically distributed between the baffle and the fixed shell.
[0010] Optionally, it also includes a sensing block, which is fixedly connected to the bottom of the baffle.
[0011] Optionally, it also includes a mounting block, a rotating plate, and a second torsion spring. The mounting block is fixedly connected to the ball inlet at the rear of the ball guide plate, and the rotating plate is rotatably connected to the mounting block. A second torsion spring is symmetrically distributed between the rotating plate and the mounting block.
[0012] This utility model has the following advantages: 1. This utility model uses a servo motor to drive the connecting rod and crank in linkage, which drives the wedge block to move up and down. In conjunction with the energy storage spring, it realizes the energy storage and release of the hitting stick, completing the automatic ball serving action. By setting a sliding groove structure, the rotational motion of the servo motor is smoothly converted into swinging motion, which improves the stability and accuracy of the ball serving mechanism. The energy storage spring releases energy at the moment of impact, ensuring consistent hitting force and improving the fairness and competitiveness of the game. At the same time, the return plate and the ball box work together to realize automatic ball return, simplifying the operation process and improving the game continuity and user experience.
[0013] 2. This utility model uses a baffle that remains closed under the action of a first torsion spring, effectively preventing the soccer ball from accidentally slipping out before the ball is served. Combined with the automatic detection function of the induction block to detect the soccer ball's position, it realizes intelligent triggering of the serving action, improving the automation and stability of the serving process. When the batter strikes the soccer ball, the soccer ball pushes the baffle to rotate and open the serving port. After the serve is completed, the baffle returns to its original position under the action of the torsion spring, ensuring that the device can operate continuously. It not only realizes the functions of preventing accidental serves and automatic return, but also achieves the functions of preventing accidental serves and automatic return.
[0014] 3. This utility model uses the cooperation structure of the rotating plate and the second torsion spring to allow the football to smoothly enter the ball guide plate; it prevents the football from falling or slipping out when not in the serving state. The closed rotating plate can provide rigid resistance under the pre-tension of the second torsion spring, effectively preventing the football from being accidentally served, thereby improving the safety and stability of the equipment operation and avoiding misoperation under abnormal conditions.

Detailed Implementation
[0023] Example: An intelligent automatic ball-serving device for table football, such as Figures 1-7 As shown, the system includes a mounting base 1, a ball guide plate 2, a return ball guide plate 3, and a ball box 4. The ball guide plate 2 is screwed onto the top center of the mounting base 1. The ball guide plate 2 has an L-shaped structure, with an inlet on the upper rear side and an outlet on the top. Return ball guide plates 3 are symmetrically distributed on both the left and right sides of the front of the ball guide plate 2, both with inclined structures. The ball guide plate 2 has a return ball outlet at its front, and the gap between the two return ball guide plates 3 is equal to the side length of the return ball outlet. The sides of the two return ball guide plates 3 that are furthest from each other are connected to and communicate with the ball box 4. The system also includes a ball-launching switch 5, a stand plate 6, a servo motor 7, a connecting rod 8, a crank 9, a striking rod 10, a power storage spring 11, a fixing block 12, a wedge block 13, and a compression spring. A spring 14 is attached to the top left of the mounting base 1, and a ball-launching switch 5 is mounted on it via screws. A vertical plate 6 is mounted on the top right of the mounting plate via screws. A servo motor 7 is mounted on the upper right side of the vertical plate 6 via screws. The output shaft of the servo motor 7 passes through the vertical plate 6 and is welded to a connecting rod 8. A crank 9 is rotatably connected to the left side of the vertical plate 6. A groove is provided on the crank 9, and one end of the connecting rod 8 slides in the groove. A hitting stick 10 is slidably connected to the front side of the ball guide plate 2. A power storage spring 11 is connected between the hitting stick 10 and the ball guide plate 2. A fixing block 12 is welded to the front end of the hitting stick 10. A wedge block 13 is slidably connected inside the fixing block 12. The wedge block 13 abuts against one end of the crank 9. A compression spring 14 is symmetrically distributed between the wedge block 13 and the fixing block 12.
[0024] When the player presses the serve switch 5, the servo motor 7 starts, and its output shaft drives the connecting rod 8 to rotate clockwise, causing the crank 9 to move. The crank 9 has a groove that allows the connecting rod 8 to slide inside, thus converting the rotational motion of the servo motor 7 into the swinging motion of the crank 9. As the crank 9 swings, one end pushes the wedge block 13 downward, compressing the compression spring 14 installed in the fixed block 12, causing the compression spring 14 to deform. When the crank 9 continues to swing clockwise to a certain angle, it disengages from the wedge block 13. At this time, the compression spring 14 returns to its original shape, pushing the wedge block 13 back upward. Then, the output shaft of the servo motor 7 reverses, driving the connecting rod 8 to rotate counterclockwise and slide in the groove, thereby causing the crank 9 to swing counterclockwise, contacting the wedge block 13 again and pushing it forward. At the same time, the striking stick 10 moves along with the wedge block 13. As the ball moves forward, the energy storage spring 11 is compressed and stores energy. When the wedge block 13 moves to the predetermined position, the contact angle of the crank 9 changes due to its continued counterclockwise swing, causing it to suddenly disengage from the wedge block 13. At this time, the compressed energy storage spring 11 quickly releases energy, pushing the striking rod 10 to move forward rapidly, forcefully striking the football at the baffle 16. The automatic ball-serving action is completed through the ball outlet of the guide plate 2. After the ball-serving action is completed, the wedge block 13 and the striking rod 10 return to their initial positions under the action of the energy storage spring 11, and the system enters a standby state, waiting for the next ball-serving command. During the game, when one side scores a goal, the football falls into the corresponding ball box 4 and rolls along the inclined return plate 3 to the return outlet, finally entering the guide plate 2. Pressing the ball-serving switch 5 again will restart the ball from the outlet, enabling continuous play.
[0025] like Figure 1 , Figure 3 and Figure 5 As shown, it also includes a fixed shell 15, a baffle 16, a first torsion spring 17 and a sensing block 18. The fixed shell 15 is screwed onto the front of the ball guide plate 2. The baffle 16 is rotatably connected inside the fixed shell 15. The baffle 16 is located inside the ball guide plate 2. The first torsion spring 17, which is symmetrically distributed on the left and right, is connected between the baffle 16 and the fixed shell 15. The sensing block 18 is screwed onto the bottom of the baffle 16.
[0026] The baffle 16 is closed under the action of the first torsion spring 17 to prevent the football from accidentally falling or sliding out of the ball guide plate 2 before the serving action is triggered. When the football is manually placed into the goal opening and slides into the ball guide plate 2, it will be blocked by the baffle 16 and touch the sensing block 18 at its bottom. After the sensing block 18 detects that the football is in place, it can automatically start the servo motor 7 to perform the serving operation. If the football re-enters the ball guide plate 2 through the return plate 3, the striking stick 10 strikes the football forward when the ball is served again, and the football is pushed by the force of the baffle 16. Rotating clockwise, the first torsion spring 17 is compressed and deformed, and the baffle 16 opens the ball outlet, allowing the football to be hit smoothly from the outlet. After the ball is served, under the elastic force of the first torsion spring 17, the baffle 16 rotates counterclockwise to return to the initial closed position, ready for the next serve. If the football fails to be successfully launched from the outlet and rolls back along the ball guide plate 2, it will be blocked by the baffle 16 again and touch the sensor block 18. After the sensor block 18 detects the signal, it will trigger the motor to restart the ball launching operation until the football is successfully hit from the outlet.
[0027] like Figure 6 and Figure 7 As shown, it also includes a mounting block 19, a rotating plate 20, and a second torsion spring 21. The mounting block 19 is installed at the ball inlet at the rear of the ball guide plate 2 by screws. The rotating plate 20 is rotatably connected to the mounting block 19. The second torsion spring 21, which is symmetrically distributed on the left and right, is connected between the rotating plate 20 and the mounting block 19.
[0028] When a football is manually placed into the ball-guiding groove 2, the football will press against the lower part of the rotating plate 20, causing it to rotate clockwise. At this time, the second torsion spring 21 deforms, and the rotating plate 20 opens, allowing the football to smoothly enter the ball-guiding groove 2. After the football is placed, under the elastic force of the second torsion spring 21, the rotating plate 20 rotates counterclockwise to return to its initial closed state, restoring its obstruction of the ball-guiding groove. When the football attempts to bounce out of the ball-guiding groove due to excessive force or jamming, it will be blocked by the closed rotating plate 20. Because the rotating plate 20 is subjected to the pre-tension force of the second torsion spring 21, it has a certain rigid resistance, which can effectively prevent the football from accidentally bouncing out of the ball-guiding groove, thereby improving the safety and stability of the ball-launching device.
