Description

Technical Field

[0001] This invention relates to the field of gaming equipment technology, and more specifically, to a gift machine. Background Technology

[0002] Gift machines, as a type of leisure and entertainment game equipment, are widely used in shopping malls, amusement parks, arcades and other leisure and consumption venues. They are loved by consumers for their fun and interactivity and have become a common type of equipment in leisure and entertainment scenarios.

[0003] Existing prize machines generally suffer from design flaws in their core prize-drop triggering mechanisms. Specifically: First, the prizes are limited, preventing players from freely and intuitively choosing challenges of varying difficulty to obtain prizes of different values. Second, many machines use a single push rod or crank arm drive to trigger the prize drop, lacking precise positioning and sensing mechanisms, resulting in low accuracy and frequent false triggers or failures, severely impacting the user experience. Third, some machines lack a buffer protection structure when the drive mechanism interacts with the turntable; collisions between the push rod and the turntable's sidewall cause hard wear on components such as the push rod and turntable, significantly reducing the overall lifespan of the equipment. Fourth, most prize machines lack… The existing gift machine has several drawbacks. First, it is necessary to install a real-time gift detection sensor in the gift channel. Even if there is no gift at the outlet of the gift channel, the machine will still trigger an action, resulting in invalid operation and further degrading the user experience. Second, the transmission structure between the feeding mechanism and the drive mechanism of the existing gift machine is complex and has many parts. This not only increases the difficulty of equipment assembly, but also makes subsequent maintenance and troubleshooting very inconvenient. The failure rate of the equipment is relatively high, making it difficult to meet the requirements of equipment stability and convenience in commercial use scenarios. Therefore, it is urgent to develop a gift machine with a reasonable structural design, accurate prize triggering, component buffer protection, real-time gift detection, and stable operation to solve the technical problems of the existing gift machine and improve the performance and user experience of the equipment.

[0022] This invention provides a gift machine, such as Figure 1As shown, the device includes a frame 1, on which a gift outlet 10 and multiple gift storage areas separated from and connected to the gift outlet 10 are provided. Each gift storage area has an L-shaped baffle 12 rotatably mounted at its outlet. The frame 1 also includes a feeding mechanism 2 for driving the baffle 12 to rotate, a crossbar 6, a first drive mechanism 4 for driving the feeding mechanism 2 to reciprocate on the crossbar 6, a second drive mechanism 5 for driving the crossbar 6 to rotate, and a control mechanism 3.

The reset component 13 can be a reset spring or a gravity tensioning component, etc., used to reset the crossbar 6. In this embodiment, a reset spring is used, with one end fixedly connected to one end of the crossbar and the other end connected to the frame. Fixed connection; the reset member 13 is in a pre-tightened state, and when the crossbar 6 rotates, the reset member 13 is further stretched. After the external force disappears, the reset member 13 retracts and drives the crossbar 6 to reset; the input end of the feeding mechanism 2 is connected to the first driving mechanism 4, and the output end can be slidably installed on the crossbar 6 and the end can abut against the baffle 12; the output end of the second driving mechanism 5 can abut against the crossbar 6 and thus drive the crossbar 6 to rotate; the control mechanism 3 is electrically connected to the first driving mechanism 4 and the second driving mechanism 5 respectively; in this embodiment, the gift storage area is a plurality of gift channels 11 connected to the gift outlet, the number of gift storage areas is at least three, and the gifts in the three gift storage areas 11 are different for users to choose from; in other embodiments, a turntable or other style gift storage area that can realize automatic gift replenishment can be set according to the actual application situation.

[0023] Furthermore, the frame 1 is also equipped with a pushing mechanism 9 adapted to the gift channel. The pushing mechanism 9 is used to push the gifts in the gift channel 11 to the baffle 12 and is electrically connected to the control mechanism 3 to realize automatic replenishment of gifts. The feeding mechanism 2 includes an I-shaped connecting seat 21, a lever 22 and a slider 23.

The extended end can abut against the baffle 12. A guide rail is provided on the crossbar 6, and the slider 23 is slidably installed on the guide rail to realize the sliding cooperation between the feeding mechanism 2 and the crossbar 6.

[0024] The following describes the specific structure and working principle of the present invention in detail with reference to three embodiments. The core difference between the embodiments lies in the design of the turntable mechanism 7, the reciprocating push block 81 structure and the second drive mechanism 5. The structure and connection relationship of the rest, such as the frame 1, gift channel 11, baffle 12, feeding mechanism 2, first drive mechanism 4, control mechanism 3 and pushing mechanism 9, are basically the same. The repeated parts will not be described again in the subsequent embodiments. Example 1

[0025] like Figure 1-5 As shown, the gift machine in this embodiment also includes a turntable mechanism 7. The control mechanism 3, the first drive mechanism 4, the second drive mechanism 5, the turntable mechanism 7 and the pushing mechanism 9 work together to achieve precise triggering of the gift falling.

[0026] In this embodiment, the control mechanism 3 includes an electrical control box 31, a controller, selection buttons, and control buttons 32. The controller is installed inside the electrical control box 31, and the control buttons 32 are installed on the top of the electrical control box 31. The electrical control box 31 is fixedly connected to the frame 1. The controller is electrically connected to the control buttons 32, the first drive mechanism 4, the second drive mechanism 5, the turntable mechanism 7, and the pushing mechanism 9, respectively, to provide signal control for the operation of each mechanism. The selection buttons are mainly used to control the opening and closing of the first drive mechanism, and the control buttons are mainly used to control the opening and closing of the second drive mechanism. The electrical control box 31 is equipped with a complete electrical control system. The controller can be a microcontroller, MCU, PLC, or other controller that controls the orderly operation of various electrical components. In this embodiment, a PLC is selected.

[0027] In this embodiment, the first driving mechanism 4 includes a first motor 41 and a first transmission belt 42. A mounting base 14 is provided on the frame 1. The first transmission belt 42 is wrapped around one side of the mounting base 14 and is fixedly connected to the lower end of the connecting seat 21 of the feeding mechanism 2. The first motor 41 is mounted on the mounting base 14 and its output end is connected to the output end of the first transmission belt 42. The first motor 41 drives the connecting seat 21 to move back and forth through the first transmission belt 42, thereby driving the feeding mechanism 2 to slide on the guide rail of the crossbar 6.

[0028] In this embodiment, the turntable mechanism 7 includes a second motor 71, a reducer 72, a turntable 73, a rotating shaft, and a second transmission belt 74. The second motor 71 and the reducer 72 are both mounted on the mounting base 14. The output end of the second motor 71 is connected to the input end of the reducer 72. The second transmission belt 74 is wound around the output end of the reducer 72 and one end of the rotating shaft. The other end of the rotating shaft passes through the mounting base 14 and is fixedly connected to the turntable 73. The turntable 73 is provided with several through holes 75 at equal intervals that are adapted to the push rods 55 of the second drive mechanism 5. The second motor 71 is electrically connected to the controller. The controller can control the second motor 71 to drive the turntable 73 to rotate continuously or stop immediately.

[0029] In this embodiment, the second drive mechanism 5 includes a third motor 51, a first rack 52, a first gear adapted to the first rack 52, a bearing housing 53, a linear bearing 54, a push rod 55, a limiting sleeve 56, and a buffer spring 57. A stand is provided on the frame 1. The first rack 52 is fixedly installed on one side of the upper surface of the stand along the direction of the turntable 73 and is perpendicular to the turntable 73. A slide rail is provided on the other side of the upper surface of the stand. The bearing housing 53 is slidably installed on the slide rail. A mounting cavity is provided on the bearing housing 53. The first gear is installed in the mounting cavity, and its lower end passes through the bottom of the bearing housing 53 and meshes with the first rack 52. Motor 51 is mounted on one side of bearing housing 53, and its output end passes through the side wall of bearing housing 53 and is fixedly connected to the first gear; linear bearing 54 is mounted on the top of bearing housing 53, one end of push rod 55 can pass through the through hole 75 of turntable 73 and abut against crossbar 6, and the other end is fixedly connected to limit sleeve 56. Limit sleeve 56 is slidably sleeved on one end of piston rod of linear bearing 54. One end of buffer spring 57 is fixedly connected to linear bearing 54, and the other end abuts against limit sleeve 56; a photoelectric switch 512 for detecting piston rod is provided at the end of linear bearing 54 away from push rod 55. Linear bearing 54 and third motor 51 are electrically connected to controller.

[0030] In this embodiment, the feeding mechanism 9 includes a sixth motor, a second sensor for detecting whether there is a gift on the baffle 12, a feeding plate 91, a feeding base 92, a lead screw, and a lead screw nut adapted to the lead screw. The feeding base 92 is installed at the bottom of the end of the gift channel 11 away from the gift outlet 10. The sixth motor is installed on the feeding base 92. The lead screw is installed on one side of the gift channel 11 along the length direction of the gift channel 11, and its input end is connected to the output end of the sixth motor. The lead screw nut is slidably installed on the lead screw and fixedly connected to the feeding plate 91. The second sensor is installed inside the gift channel 11, on the side close to the baffle, with its sensing end facing the baffle 12. The sixth motor and the second sensor are electrically connected to the controller, respectively.

[0031] During the implementation process, the second sensor in the gift channel 11 is always in working condition, detecting in real time whether there are gifts at the baffle 12. If no gifts are detected, the second sensor will send a signal to the controller, which will then control the sixth motor to start. The sixth motor drives the lead screw to rotate, which in turn moves the lead screw nut and the pusher plate 91 along the length of the gift channel 11, pushing the gifts in the gift channel 11 to the baffle 12. After the gift replenishment is completed, the sixth motor stops working.

[0032] Turntable 73 pre-rotation: When control button 32 is not pressed, the controller controls the second motor 71 to drive the turntable 73 to rotate continuously, preparing for the gift draw. When drawing a gift, the controller controls the first motor 41 to drive the lever 22 to move back and forth on the crossbar 6. The user can press the selection button to control the lever 22 to stop below the baffle 12 corresponding to the gift channel 11 where the desired gift is placed.

[0033] Prize-winning trigger operation: After the user presses the control button 32, the control button 32 sends a signal to the controller, which immediately controls the second motor 71 to stop working, and the turntable 73 stops rotating synchronously; then the controller controls the third motor 51 to start, the third motor 51 drives the first gear to mesh along the first rack 52, driving the bearing seat 53 to move along the slide rail of the stand towards the turntable 73, and then driving the push rod 55 to move forward; if the push rod 55 passes through the through hole 75 of the turntable 73 and abuts against the crossbar 6, as the push rod 55 continues to push forward, the crossbar 6 rotates, driving the lever 22 of the feeding mechanism 2 to rotate, the extended end of the lever 22 abuts against the L-shaped baffle 12 and drives the baffle 12 to rotate, opening the outlet of the gift channel 11, and the gift falls to the gift outlet 10 under the action of gravity, completing the prize-winning operation.

[0034] Unsuccessful Prize Protection and Reset: If the push rod 55 does not enter the through hole 75 of the turntable 73 and comes into contact with the side wall of the turntable 73, the squeezing force on the push rod 55 is transmitted to the limiting sleeve 56. The limiting sleeve 56 compresses the spring, and at the same time, the end of the push rod 55 away from the turntable 73 moves toward the photoelectric switch 512. When the photoelectric switch 512 detects the end of the push rod 55, it determines that the push rod 55 has not entered the through hole 75. In this case, it is considered a failure to win a prize, and this information is fed back to the controller. Then the controller controls the third motor 51 to work in reverse, driving the first gear to move in reverse along the first rack 52, causing the push rod 55 to pull back and reset. Subsequently, the controller controls the second motor 71 to restart, and the turntable 73 resumes continuous rotation, waiting for the next prize drawing operation. Example 2

[0035] like Figure 7-10 As shown, the core difference between this embodiment and embodiment one lies in the structure of the turntable mechanism 7 and the structure of the second drive mechanism 5. In this embodiment, the crank arm 513 replaces the top rod 55 in embodiment one, and the receiving groove 76 of the turntable 73 replaces the through hole 75. The rotation trigger of the crossbar 6 is achieved through the cooperation of the cam pressure wheel and the crank arm 513. The structure and connection relationship of the remaining components are the same as those in embodiment one.

[0036] In this embodiment, a plurality of receiving slots 76 adapted to the curved arm 513 are provided at equal intervals on the outer periphery of the disk, replacing the through holes 75 on the turntable 73 in Embodiment 1. The control method of the second motor 71 driving the turntable 73 to rotate is the same as in Embodiment 1.

[0037] In this embodiment, the second drive mechanism 5 includes a third motor 51, a fourth motor 58, a fixed base 59, a first cam pressure roller 510, a second cam pressure roller 511, a first sensor 515 for detecting the rotation angle of the crank arm 513, a crank arm 513 adapted to the receiving groove 76, and a tension spring 514. The fixed base 59 is mounted on the frame 1 and has an internal mounting cavity. The crank arm 513 is rotatably connected to the fixed base 59 via a pin, with one end placed in the mounting cavity and the other end passing through the top of the fixed base 59 and positioned above the turntable 73. It can pass through the receiving groove 76 of the turntable 73 and abut against the crossbar 6. The first cam pressure roller 510 and the second cam pressure roller 511 are rotatably mounted in the mounting cavity and are respectively connected to the crank arm 513. The two sides of the crank arm 513 abut against each other, and the first cam pressure roller 510 is placed on the side of the crank arm 513 away from the mounting base 14; one end of the tension spring 514 is fixedly connected to the inner wall of the mounting cavity, and the other end is fixedly connected to the crank arm 513 and located above the first cam pressure roller 510; the third motor 51 and the fourth motor 58 are respectively installed on the outside of the fixed base 59, and their output ends pass through the side wall of the fixed base 59 and are fixedly connected to the first cam pressure roller 510 and the second cam pressure roller 511 respectively; the first sensor 515 is installed in the mounting cavity and is located below the end of the crank arm 513 placed in the mounting cavity and close to the first cam pressure roller 510. The first sensor 515, the third motor 51 and the fourth motor 58 are respectively electrically connected to the controller.

[0038] In the specific implementation process, the action flow of gift detection and push, and turntable 73 pre-rotation is completely consistent with that of Example 1. The second sensor of gift channel 11 always detects the gifts at baffle 12 in real time, and turntable 73 continues to rotate when control button 32 is not pressed.

[0039] When drawing a gift, the controller controls the first motor 41 to drive the lever 22 to move back and forth on the crossbar 6. The user can press the selection button to control the lever 22 to stop below the baffle 12 corresponding to the gift channel 11 where the desired gift is placed.

[0040] Prize-winning trigger operation: After the user presses control button 32, the controller stops the second motor 71, and the turntable 73 stops synchronously; then the controller starts the third motor 51, which drives the first cam pressure roller 510 to rotate. The crank arm 513 rotates under the cooperation of the tension spring 514 and the first cam pressure roller 510. When the end of the crank arm 513 just enters the receiving groove 76 of the turntable 73, the end of the crank arm 513 placed in the mounting cavity rotates synchronously to the sensing area of ​​the first sensor 515, and the first sensor... Sensor 515 transmits the detection signal to the controller, which immediately controls the fourth motor 58 that drives the second cam pressure roller 511 to start. During the rotation of the second cam pressure roller 511, it presses against the crank arm 513, thereby causing one end of the crank arm 513 placed in the receiving groove 76 to abut against the crossbar 6. The crossbar 6 rotates around the bearing seat, and the rotation of the crossbar 6 causes the lever 22 to rotate. The lever 22 presses against the L-shaped baffle 12 and causes the baffle 12 to rotate, opening the discharge port of the gift channel 11, so that the gift falls and the prize-winning operation is completed.

[0041] Unsuccessful prize draw reset: If the crank arm 513 does not enter the receiving slot 76 of the turntable 73, it is considered a failure to win a prize. The controller controls the third motor 51 and the fourth motor 58 to work in reverse, the first cam pressure roller 510 and the second cam pressure roller 511 reset, the crank arm 513 retracts under the action of the tension spring 514, and then the controller controls the second motor 71 to restart, the turntable 73 resumes continuous rotation, waiting for the next prize draw operation. Example 3

[0042] like Figure 11-14 As shown, this embodiment omits the turntable mechanism 7 in the previous embodiment, adds a reciprocating auxiliary pushing mechanism 8, and simplifies the design of the second drive mechanism 5. The rotation trigger of the crossbar 6 is achieved through the contact and cooperation between the crank arm 513 and the push block 81. The structure and connection relationship of the remaining components are consistent with those of Embodiment 1 and Embodiment 2.

[0043] In this embodiment, the auxiliary pushing mechanism 8 includes: a push block 81, a connecting rod 82, a second rack 83, a second gear 84, a U-shaped seat 85, and a fifth motor 86. The mounting base 14 is provided with a mounting plate and an adjustment groove adapted to the crossbar 6. The second rack 83 is mounted on the upper end surface of the mounting plate and is parallel to the crossbar 6. The lower end of the U-shaped seat 85 is slidably mounted on the mounting plate, and the upper end passes through the adjustment groove and is placed on the top of the mounting base 14. The top of the U-shaped seat 85 is provided with a receiving groove. The push block 81 has a "mountain" shaped structure and can be slidably installed on the crossbar 6 and fixedly connected to the upper end of the connecting rod 82. The lower end of the connecting rod 82 can be slidably placed in the receiving groove of the U-shaped seat 85. The fifth motor 86 is installed on the outside of the U-shaped seat 85, and its output end passes through the side wall of the U-shaped seat 85 and is fixedly connected to the second gear 84. The second gear 84 is installed on the U-shaped seat 85 and its lower end passes through the bottom of the U-shaped seat 85 and meshes with the second rack 83. The fifth motor 86 is electrically connected to the controller.

[0044] In this embodiment, the second drive mechanism 5 includes a third motor 51, a fixed base 59, a first cam pressure roller 510, a tension spring 514, and a crank arm 513. The fixed base 59 is mounted on the frame 1 and has an internal mounting cavity. The crank arm 513 is rotatably connected to the fixed base 59 via a pin, with one end placed in the mounting cavity and the other end passing through the fixed base 59 to abut against the push block 81. The first cam pressure roller 510 is mounted in the mounting cavity and is located on the side of the crank arm 513 that is placed in the mounting cavity, close to the mounting base 14, and can abut against the crank arm 513. One end of the tension spring 514 is fixedly connected to the inner wall of the mounting cavity on the side close to the first cam pressure roller 510, and the other end is fixedly connected to the bottom of the end of the crank arm 513 that is placed in the mounting cavity. The third motor 51 is electrically connected to the controller and is used to drive the first cam pressure roller 510 to rotate.

[0045] In the specific implementation process, the gift detection and pushing are consistent with the first and second embodiments. The second sensor of the gift channel 11 detects the gifts at the baffle 12 in real time, and the controller controls the pushing mechanism 9 to complete the automatic replenishment based on the detection signal.

[0046] When drawing a gift, the controller controls the first motor 41 to drive the lever 22 to move back and forth on the crossbar 6. The user can press the selection button to control the lever 22 to stop below the baffle 12 corresponding to the gift channel 11 where the desired gift is placed.

[0047] Push block 81 reciprocates: When the control button 32 is not pressed, the controller controls the fifth motor 86 to work continuously. The fifth motor 86 drives the second gear 84 to mesh and move along the second rack 83, which drives the U-shaped seat 85 to reciprocate laterally along the mounting plate. The U-shaped seat 85 drives the push block 81 to reciprocate laterally on the crossbar 6 through the connecting rod 82, in preparation for the gift to be drawn.

[0048] Prize-winning trigger operation: After the user presses the control button 32, the control button 32 sends a signal to the controller, which immediately controls the fifth motor 86 to stop working, and the push block 81 stops moving synchronously; then the controller controls the third motor 51 to start, the third motor 51 drives the first cam pressure roller 510 to rotate, and the crank arm 513 presses down under the cooperation of the first cam pressure roller 510 and the tension spring 514; if the crank arm 513 abuts against the push block 81, the push block 81 is squeezed and drives the crossbar 6 to rotate around the bearing seat, the crossbar 6 rotates and drives the lever 22 to rotate, the lever 22 drives the baffle 12 to rotate, opening the outlet of the gift channel 11, and the gift falls to the gift outlet 10, completing the prize-winning operation.

[0049] Unsuccessful prize draw reset: If the crank arm 513 does not contact the push block 81, it is considered a failure to win a prize. The controller controls the third motor 51 to work in reverse, the first cam pressure roller 510 resets, the crank arm 513 retracts under the action of the tension spring 514, and then the controller controls the fifth motor 86 to restart, the push block 81 resumes reciprocating lateral movement, waiting for the next prize draw operation.
