[0032] The following is for reference. Figures 1-5 Description of a coin-shooting device 100 according to an embodiment of the present invention.

[0033] Example 1

[0034] like Figure 1As shown, this embodiment provides a coin-firing device 100, which includes a coin-firing mechanism 1 and a rotating support structure 2.

[0035] A rotating support structure 2 is disposed below the coin-firing mechanism 1, and can support the coin-firing mechanism 1. The rotating support structure includes a base 21 and a slewing bearing 22, which is disposed between the base 21 and the coin-firing mechanism 1. The slewing bearing 22 includes an inner ring and an outer ring that can rotate relative to each other. One of the base 21 and the coin-firing mechanism 1 is fixedly connected to the inner ring of the slewing bearing 22, and the other is fixedly connected to the outer ring of the slewing bearing 22.

[0036] like Figure 5 As shown, it should be further explained that the slewing bearing 22 is a large bearing capable of withstanding comprehensive loads, including large axial and radial loads and overturning moments. The slewing bearing 22 includes an inner ring 222 and an outer ring 223 that can rotate relative to each other, and the inner ring 222 and the outer ring 223 are coaxially arranged; the slewing bearing 22 also includes rolling elements, which are disposed between the inner ring and the outer ring.

[0037] Optionally, the base 21 can be fixedly connected to the inner ring 222 of the slewing bearing 22, and the coin-shooting mechanism 1 can be fixedly connected to the outer ring 223 of the slewing bearing 22.

[0038] Optionally, the coin-shooting mechanism 1 can be fixedly connected to the inner ring 222 of the slewing bearing 22, and the base 21 can be fixedly connected to the outer ring 223 of the slewing bearing 22.

[0039] In a specific example, the inner ring 222 is provided with a plurality of inner ring fastening holes arranged circumferentially, and the base 1 is provided with a base connecting hole. The connecting fasteners are fixedly connected to the base 21 through the base connecting hole and the fastening hole on the inner ring 222. The outer ring 223 is provided with a plurality of outer ring fastening holes arranged circumferentially, and the coin-shooting mechanism is provided with a mechanism connecting hole. The connecting fasteners are fixedly connected to the outer ring fastening hole and the mechanism connecting hole.

[0040] It should also be noted that the coin-shooting mechanism 11 refers to a device capable of launching game coins. It uses a power source to provide initial velocity to the game coin, causing it to fly in a specific direction. In many coin-shooting game machines, the user receives points or rewards after the launched coin hits a target or enters a predetermined collection area. To increase the fun of this type of game machine, the user's own actions determine whether a reward is awarded each time they play.

[0041] The coin-shooting device 100 in this embodiment has the following advantages: (1) By mounting the coin-shooting mechanism 1 on the rotating support structure 2, the firing angle of the coin-shooting mechanism 1 can be adjusted, thereby increasing the playability and function of the coin-shooting mechanism 1; (2) The base 21 and the coin-shooting mechanism 1 are connected by a slewing bearing 22, which can improve the stability and reliability of the support for the coin-shooting mechanism 1, thereby making the entire coin-shooting device 100 run more stably and reliably.

[0042] In a specific example, the coin-shooting device 100 also includes a protective plate 6, which is fixedly connected to the base 21 and forms a mounting cavity between the protective plate 6 and the base 21, with a slewing bearing 22 disposed in the mounting cavity.

[0043] Example 2

[0044] like Figure 1 As shown, the coin-firing mechanism 1 is further fixedly connected to the outer ring 223 of the slewing bearing 22. The coin-firing device 100 also includes a drive device 3 and a direction control device. The drive device 3 is mounted on the base 21 and is used to drive the outer ring 223 of the slewing bearing 22 to rotate. The direction control device is electrically connected to the drive device 3. The user controls the running direction of the drive device 3 through the direction control device, so that the drive device 3 can drive the outer ring 223 of the slewing bearing 22 to rotate clockwise or counterclockwise, thereby causing the outer ring 223 of the slewing bearing 22 to drive the coin-firing device 100 to rotate clockwise or counterclockwise. Thus, the user can adjust the launching angle of the coin-firing structure by operating the direction control device, further improving the gaming experience.

[0045] like Figure 1 As shown, the coin-firing device 100 further includes a position sensor 5 and an automatic control device, the automatic control device being electrically connected to the position sensor 5 and the drive device 3; the position sensor 5 includes a photoelectric sensor and a photoelectric sensor trigger 54; the photoelectric sensor trigger 54 is fixed on the coin-firing mechanism 1; the photoelectric sensor is fixed on the base 21; the photoelectric sensor trigger 54 is used to trigger the photoelectric sensor to obtain the position of the coin-firing mechanism 1; the coin-firing mechanism 1 has a first limit position and a second limit position relative to the base 21; the automatic control device is configured to control the drive device 3 to shut down when the coin-firing mechanism 1 is in the first limit position or the second limit position.

[0046] By setting up position sensor 5 and automatic control device, the coin-shooting mechanism 1 can be limited to the first limit position and the second limit position, which helps to avoid the coin-shooting mechanism 1 from rotating too much and colliding with other amusement facilities or tourists.

[0047] Specifically, the driving device 3 can be divided into a first state and a second state during operation. When the driving device 3 is in the first state, it drives the outer ring 223 of the slewing bearing 22 to rotate clockwise. When the outer ring 223 of the slewing bearing 22 rotates clockwise, the orientation of the coin-feeding mechanism 11 changes towards the first direction. Taking clockwise rotation as an example, when the outer ring 223 of the slewing bearing 22 rotates clockwise, the orientation of the coin-feeding mechanism 1 deflects to the right; therefore, the first direction is to the right. When the driving device 3 is in the second state, it drives the outer ring 223 of the slewing bearing 22 to rotate counterclockwise. When the outer ring 223 of the slewing bearing 22 rotates counterclockwise, the orientation of the coin-feeding mechanism 1 changes towards the second direction, which is opposite to the first direction. Taking counterclockwise rotation as an example... Figure 1 In the structure shown, when the outer ring 223 of the slewing bearing 22 rotates counterclockwise, the orientation of the coin-firing mechanism 1 deflects to the left; therefore, the second direction is to the left. In summary, the first and second states of the drive device 3 correspond to two directions that change the orientation of the coin-firing mechanism 1, thereby allowing the coin to be flexibly controlled to change its orientation.

[0048] When the coin-shooting mechanism 1 is in game mode, the state of the drive device 3 should be controlled by the user. Therefore, this embodiment also includes a direction control device. The direction control device is electrically connected to the drive device 3 and is used to control the drive device 3 to enter either the first or second state. Different user operations on the direction control device can cause the drive device 3 to enter either the first or second state. For example, the direction control device includes an operating joystick. When the operating joystick is moved to the right, the outer ring 223 of the slewing support 22 enters the first state and begins to rotate clockwise, causing the coin-shooting mechanism 1 to deflect to the right. When the operating joystick is moved to the left, the outer ring 223 of the slewing support 22 enters the second state and begins to rotate counterclockwise, causing the coin-shooting mechanism 1 to deflect to the left. In this way, the user's operating direction can be synchronized with the direction change of the coin-shooting mechanism 1, enhancing the gaming experience.

[0049] The first extreme position here is the limit rotational position of the coin-firing mechanism 1 when it moves along the first direction, and the second extreme position is the limit rotational position of the coin-firing mechanism 1 when it moves along the second direction. For example... Figure 2As shown, the position sensor 5 includes a photodetector trigger 54, a first photodetector 51, and a second photodetector 52. The photodetector trigger 54 is mounted on the base 13 of the coin-firing mechanism 1. When the coin-firing mechanism 1 rotates, the photodetector trigger 54 rotates with it, and is used to identify the position of the coin-firing mechanism 1. When the photodetector trigger 54 reaches a specific position, it can block the light emitted by the photodetector, thereby triggering a positioning signal. During the rotation of the outer ring 223 of the slewing bearing 22, the photodetector trigger 54 passes through the detection areas of the first photodetector 51 and the second photodetector 52, respectively. The first photodetector 51 and the second photodetector 52 are used to determine whether the coin-firing mechanism 1 has reached the first limit position and the second limit position, respectively. When the coin-firing mechanism 1 is at the first limit position in the first direction or the second limit position in the second direction, the automatic control device controls the drive device 3 to stop driving. Specifically, the first photodetector 51 is used to output a first positioning signal to the automatic control device when the photodetector trigger 54 is within its own detection area. The purpose of setting up the first photodetector 51 is to detect whether the coin-firing mechanism 1 has reached the first limit position in the first direction. Therefore, a first preset position needs to be designed based on the position of the photodetector trigger 54 when the coin-firing mechanism 1 reaches the first limit position, so that the photodetector trigger 54 is located in the detection area of ​​the first photodetector 51 when the coin-firing mechanism 1 reaches the first limit position. In this way, when the coin-firing mechanism 1 reaches the first limit position, the automatic control device can receive the first positioning signal. If the drive device 3 is still in the first state after the coin-firing mechanism 1 triggers the first positioning signal, the automatic control device controls the drive device 3 to stop working. Similarly, the second photodetector 52 is used to output a second positioning signal to the automatic control device when the photodetector trigger 54 is located in its own detection area. The purpose of setting up the second photodetector 52 is to detect whether the coin-firing mechanism 1 has reached the second limit position. Therefore, a second preset position needs to be designed based on the position of the photodetector trigger 54 when the coin-firing mechanism 1 reaches the second limit position, so that the photodetector trigger 54 is located in the detection area of ​​the second photodetector 52 when the coin-firing mechanism 1 reaches the second limit position. In this way, when the coin-firing mechanism 1 reaches the second limit position, the automatic control device can receive the second positioning signal. If the drive device 3 is still in the second state after the coin-firing mechanism 1 triggers the second positioning signal, the automatic control device will control the drive device 3 to stop working.

[0050] The coin-firing device 100 also includes a third photocell 53. The third photocell 53 is used to output a third positioning signal to the automatic control device when the photocell trigger 54 is within its detection area. The purpose of setting the third photocell 53 is to detect whether the coin-firing mechanism 1 has returned to the preset initial position. Therefore, a third preset position needs to be designed based on the position of the photocell trigger 54 when the coin-firing mechanism 1 reaches the preset initial position, so that when the coin-firing mechanism 1 reaches the preset initial position, the photocell trigger 54 is within the detection area of ​​the third photocell 53. In this way, when the coin-firing mechanism 1 is in the preset initial position, the automatic control device can receive the third positioning signal. Therefore, the automatic control device can determine whether the coin-firing mechanism 1 has returned to the preset initial position based on the third positioning signal. The specific control method for returning to the preset initial position can be: the automatic control device can drive the turntable to rotate forward by controlling the drive device 3. Before reaching the corresponding limit, if the automatic control device receives the third positioning signal, it controls the drive device 3 to stop working; otherwise, when the automatic control device receives the first positioning signal, it controls the drive device 3 to stop working. At this point, the automatic control unit drives the turntable to rotate in reverse via the control drive device 3 until the automatic control unit receives the third stop signal, at which point the control drive device 3 stops working. Alternatively, the automatic control unit can drive the turntable to rotate in reverse via the control drive device 3. Before reaching the corresponding limit, if the automatic control unit receives the third stop signal, it stops working; otherwise, it stops working when the automatic control unit receives the second stop signal. At this point, the automatic control unit then drives the turntable to rotate clockwise via the control drive device 3 until the automatic control unit receives the third stop signal, at which point the control drive device 3 stops working.

[0051] Example 3

[0052] like Figure 2 As shown, the outer circumferential surface of the outer ring is further constructed as a first gear structure 221, and the output end of the drive device 3 is constructed as a second gear structure 31. The first gear structure 221 and the second gear structure 31 mesh and transmit power. Gear meshing transmission helps to improve the accuracy and stability of the transmission.

[0053] Example 4

[0054] like Figure 4 As shown, the coin-shooting device 100 further includes a first limiting structure 41 and a second limiting structure 42, with the coin-shooting mechanism 1 movably positioned between the first limiting structure 41 and the second limiting structure 42. The rotation of the coin-shooting mechanism 1 is restricted within a certain space, which helps reduce the probability of collisions between the coin-shooting mechanism 1 and other amusement facilities or visitors in the venue, thus improving safety.

[0055] It should be further explained that the cooperation between the position sensor and the automatic control device limits the rotation of the coin-firing device 100 between the first and second limit positions through electrical control. The first limiting structure 41 and the second limiting structure 42 provided in this embodiment, however, limit the rotation of the coin-firing device 100 between the first and second limit positions through mechanical means.

[0056] Specifically, when the coin-firing mechanism 1 is at the first extreme position, a corresponding first limiting structure 41 is set to stop the coin-firing mechanism 1 from continuing to move in a direction exceeding the first extreme position; when the coin-firing mechanism 1 is at the second extreme position, a corresponding second limiting structure 42 is set to stop the coin-firing mechanism 1 from continuing to move in a direction exceeding the second extreme position. The position between the first limiting structure 41 and the base 21 is relatively fixed, and the position between the second limiting structure 42 and the base 21 is relatively fixed.

[0057] In a specific application scenario, the amusement park has many attractions and a large number of visitors. The amusement facilities need to be confined to a certain space. This is conducive to planning the specific arrangement of different amusement facilities, thereby reducing the probability of interference between the coin-shooting mechanism 1 and other amusement facilities and visitors in the venue, and improving safety.

[0058] Example 5

[0059] like Figure 3 and Figure 4 As shown, the coin-firing device 100 further includes a fixing plate 4; the fixing plate 4 is provided with a guide rail 43, which extends around the axis of the slewing bearing 22. One end of the guide rail 43 in the extension direction is provided with a first limiting structure 41, and the other end of the guide rail 43 in the extension direction is provided with a second limiting structure 42. A guide member 12 is fixedly connected to the coin channel 11 of the coin-firing device 100, and the guide member 12 is guided and cooperates with the guide rail 43.

[0060] It should be noted that the coin channel 11 of the coin-firing device 100 is a channel used to launch game coins.

[0061] The fixed plate 4 is fixed relative to the base 21, and the coin-shooting mechanism 1 can move relative to the fixed plate 4.

[0062] In this embodiment, on the one hand, the guide member 12 fixedly connected to the coin channel 11 can cooperate with the guide rail 43 to make the rotation of the coin firing mechanism 1 more stable, and the firing angle of the coin channel 11 can be adjusted more accurately, resulting in a better user experience; on the other hand, by integrating the guide rail 43 and the limiting structure through the fixing plate 4, it is beneficial to improve the integration of the coin firing device 100 and the compactness of the structure, thereby reducing the volume of the coin firing device 100.

[0063] like Figure 3 and Figure 4 As shown, the guide rail 43 is further constructed as an arc-shaped groove 431 formed on the fixed plate 4. The two ends of the arc-shaped groove 431 are closed so that the guide member 12 is movably disposed between the two ends of the arc-shaped groove 431. That is to say, the arc-shaped groove 431 is formed on the fixed plate 4 and the two ends of the arc-shaped groove 431 are closed. One end of the arc-shaped groove 431 in its extension direction is closed to form a first closed end 411, and the other end of the arc-shaped groove in its extension direction is closed to form a second closed end 421. In the arc-shaped groove 431, the first limiting structure 41 is constructed as the first closed end 411, and the second limiting structure is constructed as the second closed end 421. The guide member 12 is movably disposed between the first closed end 411 and the second closed end 421 of the arc-shaped groove 431. This can also reduce the arrangement cost of the first limiting structure 41 and the second limiting structure 42, and further reduce the volume of the coin-shooting device 100.

[0064] In a specific example, the coin-shooting device 100 includes a chassis (not shown in the figure), which is fixedly connected to a base and encloses a receiving cavity. The chassis has an installation port, and a fixing plate 4 can be fixed at the installation port of the chassis. A portion of the coin channel 11 and the coin-shooting outlet on the coin channel 11 protrude from the chassis through the arc-shaped groove 431 on the fixing plate 4, so that the coin channel 11 can shoot game coins out of the chassis.

[0065] Example 6

[0066] like Figure 3 and Figure 4 As shown, the guide 12 further includes a mounting plate 121, a guide roller 122 and a fastener 123. The mounting plate 121 is connected to the coin track 11 by the fastener 123. The guide roller 122 is pivotally mounted on the mounting plate 121. The two opposite sidewalls of the arc groove 431 in the groove width direction are in rolling engagement with the outer peripheral surface of the guide roller 122. The groove width direction is perpendicular to the extension direction of the arc groove 431.

[0067] In this embodiment, the outer periphery of the guide roller 122 rolls into contact with the wall of the arc-shaped groove 431. One side wall of the arc-shaped groove 431 in the groove width direction abuts against the outer peripheral surface of the guide roller 122, and the other side wall of the arc-shaped groove 431 in the groove width direction abuts against the outer peripheral surface of the guide roller 122. Both opposite side walls of the arc-shaped groove 431 in the groove width direction roll into contact with the outer peripheral surface of the guide roller 122. This reduces the swaying of the guide roller 122 in the groove width direction when it moves in the arc-shaped groove 431, thus improving the stability of the guide. At the same time, compared with the direct friction between the coin track 11 and the arc-shaped groove 431, the rotation of the guide roller 122 can effectively reduce the friction.

[0068] like Figure 4As shown, the mounting plate 121 further includes a first support plate 1211 and a second support plate 1212; the first support plate 1211 extends along a direction parallel to the arcuate groove 431, and the second support plate 1212 connects the two ends of the first support plate 1211; the second support plate 1212 is provided with fastening holes, and fasteners 123 pass through the fastening holes to fix and connect the coin track 11; both ends of the first support plate 1211 are provided with guide rollers 122. Therefore, when the coin track 11 is located at the end of the arcuate groove 431 and has a tendency to exceed the limit, the outer peripheral surface of the guide roller 122 can abut against the groove wall at the end of the arcuate groove 431, avoiding direct contact between the coin track 11 and the arcuate groove 431, thereby reducing the risk of damage to the coin track 11.

[0069] Example 7

[0070] like Figures 1-3 As shown, the coin-firing mechanism 1 further includes a base frame 13, a coin storage device 15, a coin pusher 14, and a coin channel 11. The coin storage device 15, the coin pusher 14, and the coin channel 11 are all mounted on the base frame 13. A fixing structure 131 is provided on the base frame 13, and the base frame 13 is connected to a slewing bearing 22 via the fixing structure 131. The coin storage device 15 has a coin outlet connected to the coin channel 11.
