DETAILED DESCRIPTION

[0027] The embodiments of the technical solutions of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, but cannot limit the protection scope of the present application.

[0028] It should be noted that the technical terms or scientific terms used in the present application should be understood as the general meaning understood by the skilled person in the field to which the present application belongs, unless otherwise specified.

[0029] Please refer to Figs. 1 to 3 As shown in the drawings, the embodiment of the present application provides a table tennis ball serving device, which comprises a fixing frame 100, a ball storage device 200, a rotating assembly 300 and a payment electric controller 500.

[0030] The fixing frame 100 comprises a first fixing plate 110 and a second fixing plate 120 arranged oppositely, and a placing space 101 is formed between the first fixing plate 110 and the second fixing plate 120; the fixing frame 100 provides a mounting base and structural support for the entire device, and integrates the core components such as the ball storage device 200 and the rotating assembly 300 in the same space to ensure the positional stability of each component.

[0031] The ball storage device 200 is arranged in the placing space 101, and comprises a ball storage plate 210 and a ball serving plate 220; the ball serving plate 220 is fixedly arranged in the placing space 101, and the ball storage plate 210 is movably arranged in the placing space 101; the ball storage plate 210 is provided with a ball storage groove 211 for storing balls 800, and the ball serving plate 220 is provided with a sliding groove 201 for releasing the balls 800, and the end of the sliding groove 201 close to the first fixing plate 110 has a low drop, and the end close to the second fixing plate 120 has a high drop, so that the balls 800 move to the end with a low drop; the ball storage device 200 is the main component for storing and releasing the balls 800. The ball storage plate 210 stores and releases the balls 800 by position switching. That is, when the ball storage plate 210 is at a first position close to the ball serving plate 220, the ball storage groove 211 stably stores the balls 800; when the ball storage plate 210 is at a second position away from the ball serving plate 220, the balls 800 are separated from the ball storage groove 211 and fall into the ball serving plate 220, such as by the self-gravity of the balls 800, and slide from the ball storage groove 211 to the ball serving plate 220.

[0032] The ball serving plate 220 is fixedly arranged in the placing space 101 and is provided with the sliding groove 201, and the sliding groove 201 has a height difference between the two ends, that is, the end close to the first fixing plate 110 is low, and the end close to the second fixing plate 120 is high. The sliding groove 201 guides the movement of the balls 800, and when the balls 800 are released from the ball storage plate 210 to the ball serving plate 220, the balls 800 automatically roll to the low end by the drop of the sliding groove 201, and the orderly output of the balls 800 is completed.

[0033] The rotating assembly 300 is arranged on the fixed frame 100, and the rotating assembly 300 is connected to the ball storage plate 210. The rotating assembly 300 drives the ball storage plate 210 to move between a first position close to the ball launching plate 220 and a second position away from the ball launching plate 220. The ball storage plate 210 stores the ball 800 in the first position, and releases the ball 800 to the ball launching plate 220 in the second position. The rotating assembly 300 is mounted on the fixed frame 100 and directly connected to the ball storage plate 210. The rotating assembly 300 is a power execution component for driving the ball storage plate 210 to switch positions. After receiving a driving signal, the rotating assembly 300 drives the ball storage plate 210 to move between the first position and the second position, and switches the ball 800 from the storage state to the release state through mechanical movement. Wherein Fig. 3 The dashed arrow indicates the direction in which the ball 800 slides from the ball storage plate 210 to the ball launching plate 220 and moves on the ball launching plate 220.

[0034] The payment controller 500 is electrically connected to the rotating assembly 300, and the payment controller 500 provides a driving signal to the rotating assembly 300. The payment controller 500 receives a payment signal and outputs a driving signal to the rotating assembly 300. After the user completes the payment operation, the payment controller 500 triggers signal transmission to drive the rotating assembly 300 to act, thereby indirectly controlling the ball storage plate 210 to release the ball 800 and realizing the automatic linkage of payment and ball launching.

[0035] In addition, the payment method of the payment controller 500 includes at least coin payment, such as various game machine coin dispensers or direct coin payment, card payment, NFC near field payment, and code scanning payment.

[0036] In this embodiment, the table tennis ball launching device includes a fixed frame 100, a ball storage device 200, a rotating assembly 300, and a payment controller 500. The first fixed plate 110 and the second fixed plate 120 of the fixed frame 100 form a placement space 101. The ball storage plate 210 of the ball storage device 200 is movably arranged in the placement space 101 and contains the ball 800 through the ball storage groove 211. The rotating assembly 300 drives the ball storage plate 210 to move between a first position for storing the ball 800 and a second position for releasing the ball 800. When the ball storage plate 210 moves to the second position, the ball 800 is released onto the ball launching plate 220. The slide groove 201 of the ball launching plate 220 causes the ball 800 to move in the direction of the drop. The payment controller 500 is electrically connected to the rotating assembly 300. After the user pays, the payment controller 500 provides a driving signal to the rotating assembly 300, which drives the ball storage plate 210 to rotate and launch the ball. The entire process is automatically operated, effectively improving the ball launching efficiency.

[0037] In the present application, the rotating assembly 300 comprises a speed reducer motor, which is arranged on the side of the first fixed plate 110 away from the second fixed plate 120. The speed reducer motor comprises a motor and a speed reduction gear.

[0038] The motor and the payment electric controller 500 are electrically connected. The motor, as a power source, is electrically connected with the payment electric controller 500. After receiving the driving signal transmitted by the payment electric controller 500, the motor starts to rotate and outputs original power.

[0039] The speed reduction gear is drivingly connected with the motor. The speed reduction gear is used to reduce the output rotation speed and increase the output torque. The speed reduction gear is drivingly connected with the motor to realize speed reduction and torque increase. The high rotation speed and low torque power output by the motor is transmitted through the speed reduction gear, so that the rotation speed is reduced and the torque is increased. Therefore, the speed reducer motor can drive the ball storage plate 210 and other components to complete accurate position switching with more suitable power parameters, so as to ensure the stability and power requirement of the release action of the ball 800.

[0040] The speed reducer motor is installed on the side of the first fixed plate 110 away from the second fixed plate 120. The motor provides power to the speed reduction gear to adjust the power parameters, converts the electric energy into mechanical energy meeting the requirements of mechanical action, and drives the ball storage plate 210 to complete the storage and release switching of the ball 800.

[0041] The rotating assembly 300 further comprises a rotating shaft gear and a rotating shaft.

[0042] The rotating shaft gear is connected with the speed reduction gear. One side of the rotating shaft gear is engaged with the speed reduction gear to receive the motor power after speed reduction, and the other side transmits the power to the rotating shaft through gear engagement, so that the rotating power of the motor can be continuously transmitted.

[0043] The rotating shaft is arranged through the first fixed plate 110. The rotating shaft connects the components on both sides of the first fixed plate 110. The power is transmitted from the outside to the inside of the first fixed plate 110 through the rotating shaft, so that the linkage of the components on both sides is realized, thereby driving the ball storage device 200 to switch between the first position and the second position.

[0044] In an embodiment of the present application, the surfaces of the first fixed plate 110 and the second fixed plate 120 are parallel, and the second fixed plate 120 is provided with a ball return opening 121 opposite to the ball storage groove 211. The ball return opening 121 is arranged in the second fixed plate 120 and is opposite to the ball storage groove 211 of the ball storage plate 210, i.e. the positions are aligned. When the ball 800 needs to be recycled, the ball return opening 121 becomes the entrance of the ball 800 into the device. The ball 800 falls into the ball storage groove 211 along a straight line by gravity or auxiliary power, so as to ensure that the ball 800 stably returns to the storage position of the ball storage plate 210 and prepares for the next ball launching.

[0045] Referring to Fig. 3As shown, the billiard ball serving device further comprises a guide seat 600 arranged on the side of the serving plate 220 close to the first fixed plate 110, and the guide seat 600 is provided with a guide groove 610 which is connected to the serving plate 220. The guide seat 600 is arranged on the side of the serving plate 220 close to the first fixed plate 110, and the guide groove 610 of the guide seat 600 is directly connected to the sliding groove 201 of the serving plate 220, thereby forming a continuous ball tool 800 conveying path. When the ball tool 800 is released from the ball storage plate 210 to the serving plate 220, it rolls to the end with a lower drop by means of the drop of the sliding groove 201 of the serving plate 220, enters the guide groove 610 of the guide seat 600, and the guide groove 610 further restricts the movement direction of the ball tool 800 through the groove structure matching the diameter of the ball tool 800, so as to avoid the deviation of the ball tool 800 path caused by inertia deviation or collision after the ball tool 800 deviates from the serving plate 220. It ensures that the ball tool 800 is stably output from the inside of the device to the designated area of the billiard table, especially suitable for the scene that the ball tool 800 needs to pass a distance outside the device to reach the target position. Through the connection and transition of the guide groove 610, the movement uncertainty of the ball tool 800 at the connection of different components is eliminated, so as to form a coherent and controllable closed loop for the whole serving process, and the stability and accuracy of the output of the ball tool 800 are improved.

[0046] Further, the serving plate 220 comprises a first guide rod 221 and a second guide rod 222, and the sliding groove 201 is formed between the first guide rod 221 and the second guide rod 222. The first guide rod 221 is connected to the side of the guide groove 610 close to the first fixed plate 110, the second guide rod 222 is connected to the side of the guide groove 610 away from the first fixed plate 110, and the sliding groove 201 is connected to the guide groove 610. The first guide rod 221 and the second guide rod 222 are arranged in parallel and spaced apart, and the sliding groove 201 for rolling of the ball tool 800 is naturally formed between the two guide rods. The double-guide-rod structure limits the ball tool 800 from the side through the rod bodies on both sides, so as to avoid deviation of the ball tool 800 from the preset path due to gravity deviation or slight collision during rolling. At the same time, the first guide rod 221 is connected to the side of the guide groove 610 close to the first fixed plate 110, and the second guide rod 222 is connected to the side of the guide groove 610 away from the first fixed plate 110, so that the sliding groove 201 of the serving plate 220 and the guide groove 610 form a continuous channel with seamless connection. When the ball tool 800 is released from the ball storage plate 210 to the sliding groove 201, it rolls in the drop direction under the constraint of the double guide rods, and smoothly transitions into the guide groove 610 through the precise connection of the guide rod and the guide groove 610, and continues to move to the target area of the billiard table.

[0047] In an embodiment of the present application, the billiard ball serving device further comprises a shutter, which is movably arranged at the low-drop end of the chute 201 and located on the serving path of the ball 800. The shutter has a release position away from the serving path and a shielding position shielding the serving path. The design of the shutter precisely controls the serving process of the ball 800. The shutter is movably arranged at the low-drop end of the chute 201, i.e. the terminal position of the ball 800 rolling on the chute 201, and directly located on the serving path of the ball 800. The shutter blocks the serving path at the end of the chute 201. At this time, the ball 800 released from the ball storage plate 210 to the chute 201 is blocked when rolling to this position and temporarily stays in the chute 201, unable to enter the subsequent guide groove 610 or the billiard table area, thereby playing a temporary storage role. When the shutter is away from the serving path and the shielding of the ball path is removed, the ball 800 can continue to roll along the chute 201, output to the target position of the billiard table through the guide groove 610, and complete the serving action. In this way, the value of this design lies in that the shutter can flexibly control the release timing of the ball 800 according to actual needs. For example, when the user completes the payment, the payment controller 500 can drive the shutter to switch from the shielding position to the release position to allow the ball 800 to output. If the serving is to be paused, such as equipment maintenance or temporary interruption of use by the user, the shutter is switched to the shielding position to prevent the ball 800 from continuing to roll. Through the state switching of the shutter, the stable temporary storage of the ball 800 in the non-serving state is ensured, and the precise release during serving is ensured, further improving the controllability and flexibility of the device on the serving process.

[0048] In an embodiment of the present application, the payment controller 500 comprises a battery 510, a controller 520, a power plug, and a payment device 530. The controller 520 is electrically connected to the battery 510, the power plug, and the payment device 530, respectively. The controller 520 is also electrically connected to the rotating assembly 300. The battery 510 can be used as a backup power source and is electrically connected to the controller 520. When the external power supply is interrupted, the battery 510 provides power support for the device, ensures the normal operation of the basic functions of the core components such as the controller 520 and the payment device 530, and avoids the interruption of the serving process caused by unstable power supply.

[0049] The power plug is connected to the external power supply and is electrically connected to the controller 520, which is the main power source of the device. By connecting to the external power supply, the controller 520 and the rotating assembly 300 and other high-power components are provided with continuous and stable power, ensuring the long-term stable operation of the device.

[0050] In addition, the battery 510 can also be used as a direct power source, and the power plug is used to charge the battery 510.

[0051] The payment device 530 is electrically connected to the controller 520 as a component of user payment interaction, responsible for receiving user payment operations such as coin insertion, card swiping, and code scanning, and transmitting a payment success signal to the controller 520 in real time to trigger the subsequent ball launching process.

[0052] The controller 520 is electrically connected to the battery 510, the power plug, the payment device 530, and the rotating assembly 300. The controller 520 is used for power management, coordinating the power supply switching between the battery 510 and the power plug, giving priority to external power supply, and automatically switching to battery 510 power supply when power is off to ensure uninterrupted operation of the device. The controller 520 is also used for signal processing, receiving the payment signal transmitted by the payment device 530, generating a driving instruction after verification, transmitting the instruction to the rotating assembly 300 to control the ball storage plate 210 to complete the ball release action, and realizing the automation linkage of payment-ball launching. In short, the payment controller 500 supplies power to the payment device 530 through the power plug or the battery 510 to receive the payment signal, then processes the signal in the controller 520 and drives the rotating assembly 300, which forms a complete closed loop from power supply to payment control to mechanical action, and is the control unit for realizing the automatic payment and ball launching of the device.

[0053] The table tennis ball launching device also includes a first support 710 and a second support 720, which are arranged between the first fixed plate 110 and the second fixed plate 120, and are arranged in relative spacing. The first fixed plate 110 and the second fixed plate 120 form a placement space 101 by relative arrangement, while the first support 710 and the second support 720 play a role in strengthening support, reducing the deformation of the two fixed plates under stress, ensuring the stability of the shape of the placement space 101, providing a stable installation foundation for internal components such as the ball storage device 200 and the rotating assembly 300, and avoiding the misalignment of components caused by structural looseness affecting the operation accuracy.

[0054] A plug 212 is also arranged at one end of the ball storage plate 210, which limits the end of the ball 800 in the ball storage groove 211 to prevent the ball 800 from accidentally falling out of the end of the ball storage groove 211 during the movement of the ball storage plate 210 or the storage of the ball 800.

[0055] When the ball storage plate 210 is in the storage position, the plug 212 can block the ball 800 from moving to the end of the ball storage plate 210, ensuring that the ball 800 is stably stopped in the ball storage groove 211; when the ball storage plate 210 is switched to the release position under the driving of the rotating assembly 300, the cooperation between the plug 212 and the ball storage groove 211 can guide the ball 800 to be released in a preset direction, such as the sliding groove 201 of the shooting plate 220, avoiding the ball 800 from escaping from the ball storage plate 210 in other directions due to inertia, ensuring the directionality and accuracy of the release of the ball 800, and further improving the reliability of the ball storage plate 210 in storing and releasing the ball 800.

[0056] The application also provides a billiard table, which comprises a table plate and a billiard ball shooting device arranged below the table plate. The table plate serves as a carrier of billiard game and provides a hitting surface, and the billiard ball shooting device arranged below the table plate fully utilizes the idle space below the table body through compact layout, avoids occupying additional site area, and makes the overall structure more simple. After a user completes a payment operation on the table plate, a signal is transmitted to the shooting device below the table plate, triggering the linkage of components such as the rotating assembly 300 and the ball storage device 200 in the shooting device, and the ball 800 is transported to the opening area of the table plate through a preset path, realizing an automatic process of paying and shooting. This design not only retains the basic game function of the billiard table, but also solves the low efficiency of traditional manual charging and manual ball arrangement through the integrated shooting device below, improving the operation efficiency of the site and the user experience.

[0057] The embodiments of the billiard table of the application refer to the above-described billiard ball shooting device, which will not be described here again.

[0058] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the application, but not to limit them; although the application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the above embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the application, and they should be covered in the scope of the claims and the specification of the application.
