Referring to FIGS. 1, 2, and 3, the claw machine according to a preferred embodiment of the disclosure comprises a control mechanism 12, a body 1, a first driving mechanism 2, a mounting box 3, a second driving mechanism 4, a mounting rack 5, a plurality of third driving mechanisms 6, and a plurality of claw assemblies 7. The driving portion includes the body 1 and the first driving mechanism 2. The first driving mechanism 2 is mounted on the body 1, and the first driving mechanism 2 which has a power output end connected with the mounting box 3 is configured to drive the mounting box 3 to slide in a first direction X. The second driving mechanism 4 is mounted on the mounting box 3, and the second driving mechanism 4 which has a power output end connected with the mounting rack 5 is configured to drive the mounting rack 5 to slide in a second direction Y. The plurality of third driving mechanisms 6 are mounted on the mounting rack 5 along a third direction Z, spaced apart from one another. Each of the plurality of third driving mechanisms 6 has a power output end connected with one of the plurality of claw assemblies 7 in one-to-one correspondence so as to drive it to slide in the second direction Y. Each of the plurality of claw assemblies 7 comprises a claw 701 and a fourth driving mechanism 702 mounted on the claw 701 so as to drive the claw 701 to open and close.

The control mechanism is electrically connected with the first driving mechanism 2, the second driving mechanism 4, each of the plurality of third driving mechanisms 6, and each of the plurality of fourth driving mechanisms 702, respectively.

Herein, the first direction X, the second direction Y, and the third direction Z are perpendicular to one another.

According to the above technical solution, by means of the control mechanism, a user may first control the first driving mechanism 2 to drive the mounting box 3 to slide in the first direction X, and control the second driving mechanism 4 to drive the mounting rack 5 to slide in the second direction Y, thereby enabling the claw assemblies 7 to arrive at a preliminary location. Then, the plurality of third driving mechanisms 6 may be respectively controlled to respectively drive respective claw assemblies 7 to slide in the second direction Y, thereby enabling the plurality of claw assemblies 7 to exactly arrive at the location for grip. Then, the plurality of claw assemblies 7 can perform simultaneous gripping. Alternatively, the control mechanism may be configured to allow users to control only the first driving mechanism 2 for driving the mounting box 3 to slide in the first direction X, and to directly control dropping and gripping of the claw assemblies 7 to simultaneously grasp a plurality of prizes by means of the control mechanism.

Due to the plurality of claw assemblies 7, several prizes may be simultaneously grasped in one gripping operation, providing increased interestingness of grip. As each of the plurality of claw assemblies 7 can slide up and down independently, it provides better accuracy.

Preferably, referring to FIGS. 4, 5, 6, and 7, a slider groove 101 and a slider 301, which cooperate with each other to guide sliding, may be provided between the body 1 and the mounting box 3. The first driving mechanism 2 comprises a first drive motor 201, a first elastic winder 202, a second elastic winder 203, a conveyor belt 204. Herein, the first elastic winder 202 and the second elastic winder 203 are respectively rotatably mounted on two ends of the body 1, two ends of the conveyor belt 204 are respectively connected with the first elastic winder and the second elastic winder, and a middle portion of the conveyor belt 204 is connected with the mounting box 3. The first drive motor 201 is configured to drive the first elastic winder 202 to rotate, so as to allow the conveyor belt 204 to unwind from the second elastic winder 203 and wind around the first elastic winder 202, or to unwind from the first elastic winder 202 and wind around the second elastic winder 203. In such a case, it achieves displacement of the conveyor belt 204 relative to the body 1.

More preferably, the slider groove 101 may be provided on the bottom surface of the body 1, the slider 301 may be mounted on the top surface of the mounting box 3, and the first elastic winder 202 and the second elastic winder 203 may be respectively disposed at two ends of the slider groove 101. The conveyor belt 204 may be accommodated in the slider groove 101, and the middle portion of the conveyor belt 204 may be connected with the slider 301. In such a case, the conveyor belt 204 can transmit the power of the first drive motor 201 to the slider 301 and drive the slider 301 to slide in the slider groove 101. Consequently, the mounting box 3 can be driven to slide in the first direction X stably and reliably.

More preferably, the claw machine may comprise two bodies 1 arranged in parallel and spaced apart from each other. Each one of the bodies 1 is provided with the first elastic winder 202, the conveyor belt, and the second elastic winder 203, which are drivingly connected in such order. The bodies 1 respectively cooperate with the mounting box 3 to achieve sliding connection by using the slider groove 101 and the slider 301, respectively. A connecting rod 8 may be provided between the two bodies 1, and two ends of the connecting rod 8 may be connected with the two first elastic winders 202, respectively. With the arrangement of the two bodies 1 spaced apart from each other and the connecting rod 8 for transmitting the power of the first drive motor 201 to the other body, the mounting box 3 can slide more stable due to constant power and synchronous sliding.

In some preferred embodiments, in particular referring to FIG. 4, a bearing housing is sleeved on the middle portion of the connecting rod 8 such that the connecting rod 8 is rotatable relative to the bearing housing. The bearing housing provided on the connecting rod 8 can ensure precise coaxiality of the two first elastic winders 202 and avoid big coaxiality error which may affect smooth sliding of the mounting box 3.

More preferably, a first position sensor 9 may be provided to sense the position of the mounting box 3 relative to the body 1. The first position sensor 9 may be electrically connected with the control mechanism. By virtue of the first position sensor 9, the sliding range of the mounting box 3 can be limited.

Two ends of each body 1 are respectively provided with the sensing component 901, and the slider 301 is provided with blocking plates 902 for respectively cooperating with a sensing component 901 for achieving sensing. The control mechanism may be configured to control the first drive motor 201 to stop operation when the outgoing beam emitted from a sensing component 901 is blocked by a blocking plate 902, which indicates that the mounting box 3 has already been displaced to a maximum displacement position.

More preferably, referring to FIG. 2, the second driving mechanism 4 comprises a second drive motor 401, a winding and unwinding device 402, a hanging wire 403, and a wire guiding wheel 404. Herein, the mounting box 3 may be provided with an accommodating cavity for accommodating the second drive motor 401 and the winding and unwinding device 402. The winding and unwinding device 402 and the wire guiding wheel 404 are rotatably arranged in the mounting box 3 and are spaced apart from each other. The power output end of the second drive motor 401 is connected with the winding and unwinding device 402, so as to drive the winding and unwinding device 402 to rotate. The hanging wire 403 has one end connected with the winding and unwinding device 402, and anther end wound around the circumference of the wire guiding wheel 404 and then extending through the bottom of the mounting box 3 to connect with the mounting rack 5.

In some preferred embodiments, in particular referring to FIG. 2, the second drive motor 401 and the winding and unwinding device 402 may be disposed in the middle portion of the accommodating cavity. The wire guiding wheels 404, which are disposed at two sides of the winding and unwinding device 402, may be symmetric around the winding and unwinding device 402. The hanging wire 403 may extend through the winding and unwinding device 402. Two ends of the hanging wire 403 may wind around the circumference of the wire guiding wheel 404 and then extend through the bottom of the mounting box 3 to connect with the mounting rack 5. In such a manner, the mounting rack 5 can be stably hung by the hanging wire 403.

Preferably, referring to FIG. 10, the bottom of the mounting box 3 may be provided with a return groove 10 for accommodating the top portion of the mounting rack 5. After each grip, due to the return groove 10, the claw assemblies 7 may automatically return to original position, such that the mounting rack 5 can be accommodated in the return groove 10.

More preferably, the mounting rack 5 and the return groove 10 are respectively provided with a return element 501 and a return hole 1001 fitting to receive the return element 501. Due to the return hole 1001 and the return element 501 matching with each other to achieve positioning, the return position of the mounting rack 5 can be further limited.

Preferably, the mounting box 3 may be provided at its bottom with a second position sensor 11, which is electrically connected with the control mechanism to sense the mounting rack 5.

In some preferred embodiments, in particular referring to FIGS. 8 and 9, the second position sensor may comprise a micro switch 1101 and a trigger element 1102. The trigger element 1102 may be provided with a pressing portion 11021 and a bearing portion 11022 which are spaced apart from each other. A connecting rack 302 may be disposed in the accommodating cavity and may be provided with a through hole 3021. The pressing portion 11021 may be connected with the connecting rack 302. The pressing portion 11021 and the bearing portion 11022 may be spaced apart from each other and disposed in such a manner that the through hole 3021, the mounting box 3, and the return groove 10 are located between the pressing portion 11021 and the bearing portion 11022. The bearing portion 11022 is located in the return groove 10, and there is a certain gap between the bearing portion 11022 and the wall of the return groove 10. The lower end surface of the bearing portion 11022 defines a trigger end. The trigger element 1102 is slidable in the second direction Y. The micro switch 1101 may be disposed at a side of the connecting rack 302 and comprise a trigger head 11011 extending through the through hole 3021 to abut against the lower end surface of the pressing portion 11021.

The trigger element 1102 may be made of metal material, preferably copper alloy. When the pressing portion 11021 moves downwards due to its own weight, it contacts with the trigger head 11011 to complete a circuit, such that the mounting rack 5 can slide in the second direction Y. When the mounting rack 5 is displaced back into the return groove 10, the upper end surface of the mounting rack 5 abuts against the bearing portion 11022 and pushes the trigger element 1102 upwards, such that the lower end surface of the pressing portion 11021 is separated away from the trigger head 11011. In such a case, the second driving mechanism 4 cannot keep lifting the mounting rack 5 anymore. By virtue of the second position sensor 11, the sliding range of the mounting rack 5 can be limited.

Preferably, the third driving mechanisms 6 and the fourth driving mechanisms 702 may be driving cylinders. The driving cylinder can achieve stable driving.

In conclusion, the claw machine having the plurality of claw assemblies according to the embodiments of the disclosure allows a plurality of prizes to be simultaneously gripped in one gripping operation, which increases interestingness in gripping. The claw of each of the claw assemblies can be independently controlled to slide up and down, enabling high precision gripping operation.

All the above are merely preferred embodiments of the disclosure. It should be noted that those skilled in the art may obtain equivalents or modifications without departing from the principle of the disclosure. The invention is intended to cover all of the equivalents and modifications included within the scope of the disclosure.
