Description

Technical Field

[0001] This utility model relates to an arm wrestling amusement machine. Background Technology

[0002] Arm wrestling is a simple yet competitive game, a direct confrontation of physical strength that allows participants to experience the application of power and the joy of competition. Traditional arm wrestling requires two players. To meet the demand for single-player enjoyment, arm wrestling arcade machines have emerged. However, typical arm wrestling arcade machines require manually switching the transmission ratio of the transmission system to adjust the force applied by the mechanical arm. This adjustment process is cumbersome, affects the continuity of the game, and complicates the transmission system's structure, hindering cost control.

[0003] In addition, traditional systems of this type of arm wrestling game machine usually use gear sets and linkage mechanisms or belt drives. After long-term use, gears will wear out and cause return errors, while belt drives are prone to slack, resulting in insufficient reliability of power transmission. Utility Model Content

[0028] See Figure 1 and Figure 2 This utility model discloses an arm-wrestling amusement machine, comprising: an amusement machine body 100, wherein a drive shaft 200 is rotatably mounted on the amusement machine body 100, and one end of the drive shaft 200 is connected to a power arm 300 for a user to grip; a motor 400, disposed on the amusement machine body 100, wherein the output shaft of the motor 400 is connected to an electromagnetic clutch 500; a reduction transmission system, connected between the other end of the drive shaft 200 and the electromagnetic clutch 500; and an adjustment module 600, disposed on the amusement machine body 100 and electrically connected to the electromagnetic clutch 500, for adjusting the torque that the electromagnetic clutch 500 can transmit.

[0029] The above-described arm wrestling amusement machine uses a motor 400 to drive the power arm 300 on the drive shaft 200 to rotate via an electromagnetic clutch 500 and a reduction transmission system, thereby simulating the arm wrestling game mode. The adjustment module 600 adjusts the torque that the electromagnetic clutch 500 can transmit. The electromagnetic clutch 500 has a large adjustable torque range, is convenient to adjust, and the adjustment is more linear. Moreover, the structure is relatively simple.

[0030] See Figure 2 In some embodiments of this utility model, the reduction transmission system includes a reduction gearbox 740. A first chain drive assembly 710 is provided between the output shaft of the reduction gearbox 740 and the end of the drive shaft 200 away from the power arm 300. The input shaft of the reduction gearbox 740 is connected to the output end of the electromagnetic clutch 500 via a coupling 720. A second chain drive assembly 730 is provided between the input end of the electromagnetic clutch 500 and the output shaft of the motor 400. It can be understood that the motor 400 drives the main shaft 520 of the electromagnetic clutch 500 to rotate via the second chain drive assembly 730. The main shaft 520 drives the input shaft of the reduction gearbox 740 to rotate via the coupling 720. After torque amplification by the reduction gearbox 740, the first chain drive assembly 710 drives the drive shaft 200 to rotate. The first chain drive assembly 710 and the first chain drive assembly 710 can transmit large torque, are not easy to slip, and are also suitable for use in harsh working environments. Moreover, the amusement machine body 100 is generally large in size, and the first chain drive assembly 710 and the first chain drive assembly 710 can also complete power transmission over a long distance.

[0031] See Figure 2In some embodiments of this utility model, the first chain drive assembly 710 includes a drive sprocket 711, a driven sprocket 712, a tension sprocket 713, and a chain 714. The drive sprocket 711 is fixed to the output shaft of the reduction gearbox 740, the driven sprocket 712 is fixed to the end of the drive shaft 200 away from the power arm 300, and the tension sprocket 713 is rotatably disposed on one side of the drive sprocket 711. The rotation axes of the drive sprocket 711, the driven sprocket 712, and the tension sprocket 713 are parallel to each other. The chain 714 simultaneously meshes with the drive sprocket 711, the driven sprocket 712, and the tension sprocket 713 to form a triangle. It should be noted that the chain 714 of the first chain drive assembly 710 is relatively long and is prone to slack during use. The tension sprocket 713 helps to maintain the tension of the chain 714 and improves the accuracy of the transmission ratio.

[0032] See Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the amusement machine body 100 includes a base plate 110 and a platform 120 located above the base plate 110. The power arm 300 and the drive shaft 200 are located on the platform 120. The motor 400, the electromagnetic clutch 500, the coupling 720, and the reduction gearbox 740 are all located on the base plate 110, which is beneficial for reasonable layout and utilization of the internal space of the amusement machine body 100. The base plate 110 is provided with a mounting bracket 130 on one side of the drive sprocket 711. The tension sprocket 713 is rotatably mounted on the mounting bracket 130. The mounting bracket 130 is provided with a waist-shaped hole 131 pointing towards the drive sprocket 711 in the length direction. The base plate 110 is provided with a threaded hole 111 opposite to the waist-shaped hole 131. Fastening bolts pass through the waist-shaped hole 131 and are tightened into the threaded hole 111. It is conceivable that when the tension of the chain 714 needs to be adjusted, simply loosen the fastening bolt, then push the mounting bracket 130 to move along the length of the oblong hole 131, and finally tighten the fastening bolt through the oblong hole 131 and into the threaded hole 111.

[0033] See Figure 1 In some embodiments of this utility model, in order to improve user comfort, a support cushion 800 is provided on the table 120 located in front of and below the power arm 300. The support cushion 800 is made of high-density sponge or other soft material and is used to support the user's elbow joint.

[0034] See Figure 2 and Figure 4In some embodiments of this invention, a potentiometer 210 is provided on the end face of the drive shaft 200 away from the power arm 300, rotating coaxially with it. Both the potentiometer 210 and the motor 400 are electrically connected to a control unit. The potentiometer 210 records the rotation angle of the drive shaft 200 so that the control unit can control the motor 400 to work or stop. It can be understood that when the force output by the power arm 300 is greater than the player's force, the potentiometer 210 records that the drive shaft 200 rotates a certain angle around a first clockwise direction, and the arm wrestling machine outputs a message indicating that the player has failed to win the game, while the motor 400 stops working. When the force output by the player is greater than the resistance of the power arm 300, the potentiometer 210 records that the drive shaft 200 rotates a certain angle around a second clockwise direction, and the arm wrestling machine outputs a message indicating that the player has won the game, while the motor 400 also stops working. One of the first clockwise direction and the second clockwise direction is clockwise, and the other is counterclockwise.

[0035] See Figure 2 and Figure 4 In some embodiments of this utility model, in order to limit the maximum angle of clockwise and counterclockwise rotation of the power arm 300 by means of a mechanical structure, the amusement machine body 100 is provided with two bearing seats 140 for the drive shaft 200 to pass through. The side of the drive shaft 200 is provided with a limiting rod 220 located between the two bearing seats 140. The amusement machine body 100 is provided with two first limiting blocks 150 and second limiting blocks 160 respectively located on both sides of the drive shaft 200. The first limiting block 150 and the second limiting block 160 are both made of flexible material. The limiting rod 220 rotates with the drive shaft 200 to abut against the first limiting block 150 or the second limiting block 160.

[0036] See Figure 4 In some embodiments of this utility model, in order to achieve decorative effects, create atmosphere, provide lighting, etc., the power arm 300 is provided with a light-emitting unit, and the drive shaft 200 has a wire-passing groove 230 extending along its length inside. One end of the wire-passing groove 230 is connected to the light-emitting unit, and the side wall of the drive shaft 200 has a wire outlet hole 240 connected to the other end of the wire-passing groove 230. It can be understood that the power supply circuit located inside the amusement machine body 100 is connected to the light-emitting unit through the wire outlet hole 240 and the wire-passing groove 230 in sequence, avoiding exposed wires.

[0037] See Figure 5In some embodiments of this utility model, the electromagnetic clutch 500 includes a housing 510, a main shaft 520 rotatably mounted on the housing 510, a fixed disk 530 fixedly mounted inside the housing 510, and a movable disk 540 movably passing through the main shaft 520. Friction plates 550 are provided on both sides of the movable disk 540. An elastic element 560 is provided inside the housing 510 to drive the movable disk 540 to move closer to the fixed disk 530, and a magnetic attraction assembly 570 to drive the movable disk 540 away from the fixed disk 530. It can be understood that under the action of the elastic element 560, the movable disk 540 is held against the fixed disk 530 with a large force, and the friction plates 550 are used to transmit torque. When it is necessary to reduce the transmittable torque, the magnetic attraction assembly 570 drives the movable disk 540 slightly away from the fixed disk 530. At this time, the elastic element 560 is compressed, thereby reducing the clamping force between the movable disk 540 and the fixed disk 530 on the friction plates 550. Of course, in other embodiments, the electromagnetic clutch 500 can also have other structures. The electromagnetic clutch 500 is a mature product in the mechanical field and will not be described in detail here.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
