In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel schemes. For example, "A and / or B" includes A scheme, or B scheme, or A and B scheme.

[0044] The utility model provides a lifting device of grab toy machine. Grab toy machine is a kind of entertainment facilities, and player is controlled by mechanical arm or grabbing device to be operated to grab and obtain the toy or other small articles hung or placed in machine. The lifting device of grab toy machine refers to the structural component for adjusting the position of grabbing mechanical arm or grabber in the equipment, and its main function is to control the movement of grabber in vertical direction, so that player can grab the hung or placed article in different height range.

[0045] In the embodiments of the utility model, please refer to Figures 1 to 11 The lifting device 100 of grab toy machine is used to control the up-down movement of gripper 40 of grab toy machine 200, and the lifting device 100 of grab toy machine includes driving assembly 21 and driven assembly 20 connected with each other, driven assembly 20 includes two rotating wheel groups 21 and first transmission shaft 22, first transmission shaft 22 is connected to two rotating wheel groups 21, and two rotating wheel groups 21 can rotate relative to each other, and driving assembly 21 is transmissionally connected to one rotating wheel group 21.

[0046] The side surfaces of two rotating wheel groups 21 arranged oppositely are first side surface 211 and second side surface 212 respectively, rotating wheel group 21 also includes convex part 213, convex part 213 includes first convex part 213 convexly arranged on first side surface 211 and second convex part 213 convexly arranged on second side surface 212, and first convex part 213 and second convex part 213 are arranged in dislocation.

[0047] When rotating wheel group 21 rotates, first convex part 213 and second side surface 212 are arranged in interval, second convex part 213 and first side surface 211 are arranged in interval, and first convex part 213 and second convex part 213 can rotate to abut each other.

[0048] In the present embodiment, the driving assembly 10 is responsible for providing power to operate the driven assembly 20 through transmission connection. In the toy machine 200, the driving assembly 10 is arranged to ensure that the vertical movement of the gripper 40 is effectively powered. The driven assembly 20 includes two rotating wheel sets 21 and a first transmission shaft 22, and the first transmission shaft 22 is connected to the two rotating wheel sets 21. The rotating wheel sets 21 are used to wind the hanging rope 50, and the vertical movement of the gripper 40 is achieved by the winding and unwinding of the hanging rope 50. The two rotating wheel sets 21 are oppositely arranged to provide more stable lifting control. The first transmission shaft 22 is connected to the two rotating wheel sets 21 to ensure that the power transmission is more direct and effective, and the synchronism and stability of the rotating wheel sets 21 are enhanced.

[0049] The driving assembly 21 is transmission connected to one of the rotating wheel sets 21. Since the first protrusion 2131 and the second protrusion 2132 are arranged in a staggered manner, at this time, the rotating wheel set 21 rotates first, and when it rotates to a certain angle, the first protrusion 2131 and the second protrusion 2132 abut, and the second protrusion 2132 pushes the first protrusion 2131 to rotate together, so that the two rotating wheel sets 21 rotate together. When one of the rotating wheel sets 21 rotates in the opposite direction, the second protrusion 2132 is separated from the first protrusion 2131, at this time, the rotating wheel set 21 rotates again alone until it abuts and rotates together with the first protrusion 2131. The number of the first protrusion 2131 and the second protrusion 2132 can be one or more.

[0050] The first protrusion 2131 and the second side surface 212 are arranged in a spaced manner, and the second protrusion 2132 and the first side surface 211 are arranged in a spaced manner, which can prevent friction or collision between the protrusion 213 and the opposite side surface, avoid hindering the rotation of the rotating wheel set 21 due to unnecessary contact, ensure the flexibility of the rotating wheel set 21 during rotation, and ensure that the entire lifting device can work stably.

[0051] The utility model provides a kind of lifting device 100 of grabbing toy machine, including mutually connected drive assembly 10 and driven assembly 20.Wherein, driven assembly 20 includes two runner groups 21 and first transmission shaft 22;First transmission shaft 22 is connected to two runner groups 21;Drive assembly 10 is transmission connection in one runner group 21;Two runner groups 21 oppositely arranged side are respectively first side 211 and second side 212;Runner group 21 includes protruding portion 213, protruding portion 213 includes first protruding portion 2131 protruding in first side 211 and second protruding portion 2132 protruding in second side 212;First protruding portion 2131 and second protruding portion 2132 are misaligned arrangement;When runner group 21 rotates, first protruding portion 2131 and second side 212 are spaced apart;Second protruding portion 2132 and first side 211 are spaced apart, and first protruding portion 2131 and second protruding portion 2132 can be rotated to each other abut.The utility model prevents protruding portion 213 and opposite side from generating friction or collision by first protruding portion 2131 and second side 212 spaced apart and second protruding portion 2132 and first side 211 spaced apart, to avoid abnormal noise or abrasion in runner group 21 in the process of rotation due to friction, to ensure the stable operation of lifting device.

[0052] Further, with reference to Figures 3 to 8 Lifting device 100 of grabbing toy machine further includes stop portion 23, stop portion 23 is located between first side 211 and second side 212, and stop portion 23 is located on the side of protruding portion 213 close to first transmission shaft 22;The height of protruding portion 213 on first side 211 or second side 212 is less than the length of stop portion 23 in the axial direction of first transmission shaft 22.

[0053] Since grabbing toy machine 200 in the dynamic process of grabbing doll, two runner groups 21 need to keep relatively accurate rotating matching relationship, the stop portion 23 in the embodiment is arranged between first side 211 and second side 212, which helps to constrain the relative position between two runner groups 21.In the process of runner group 21 rotation, especially when some abnormal situations (such as vibration, external force impact or doll gravity imbalance caused uneven stress of runner group 21, etc.) occur, protruding portion 213 can produce a certain degree of displacement or sway.At this time, stop portion 23 can prevent protruding portion 213 from moving excessively towards first side 211 / second side 212, ensure that protruding portion 213 is always in a relatively stable and reasonable position interval, maintain the stability of the whole runner group 21 structure, and ensure its normal operation.Stop portion 23 is rectangular, fan-shaped, etc., which is not limited here.

[0054] The stop portion 23 is arranged between the first side surface 211 and the second side surface 212. In some embodiments, the stop portion 23 is arranged only on the first side surface 211 or the second side surface 212. In other embodiments, the stop portion 23 is arranged on the first side surface 211 and the second side surface 212 respectively. The stop portion 23 can abut against the stop portion 23, or can abut against the opposite side surface.

[0055] The height of the protrusion 213 on the first side surface 211 or the second side surface 212 is less than the length of the stop portion 23 in the axial direction of the first transmission shaft 22. This allows the protrusion 213 to displace within the gap between the stop portion 23 and the opposite side surface. When the protrusion 213 abnormally displaces close to the opposite side surface, the stop portion 23 can timely block the protrusion 213 to ensure that the protrusion 213 does not exceed the range defined by the stop portion 23, thereby maintaining the stability of the entire structure.

[0056] The stop portion 23 is arranged on the side of the protrusion 213 close to the first transmission shaft 22. In other words, the protrusion 213 is arranged close to the edge of the rotating wheel set 21, and the stop portion 23 is arranged between the protrusion 213 and the first transmission shaft 22.

[0057] In this case, the protrusion 213 is beneficial to realize more efficient power transmission. The protrusion 213 close to the edge means that the force arm is large, and under the action of the same force, a larger torque can be generated, so that the driving between the rotating wheel sets 21 is more powerful, and the situation that the rotating wheel sets 21 are easily stuck can be better coped with, thereby maintaining the normal operation of the device.

[0058] If the stop portion 23 is arranged on the side of the protrusion 213 away from the first transmission shaft 22, the force arm is longer at this time. When the same external force occurs, in order to balance the torque generated by the external force, a larger contact pressure between the stop portion 23 and the surrounding components is generated, thereby causing the stop portion 23 to generate a larger friction force. In the present embodiment, the stop portion 23 is arranged between the protrusion 213 and the first transmission shaft 22, and at this time the force arm is shorter. When the same external force occurs, in order to balance the torque generated by the external force, a relatively smaller contact pressure between the stop portion 23 and the surrounding components is generated, thereby causing the stop portion 23 to generate a smaller friction force, and thereby the abnormal noise caused by friction or the wear caused by friction can be reduced.

[0059] At the same time, the stop portion 23 arranged between the protrusion 213 and the first transmission shaft 22 is helpful to realize a more compact and reasonable structure layout. At the same time, when the rotating wheel set 21 is in operation, the tension of the hanging rope 50 and the weight of the doll will generate a torque on the rotating wheel set 21. The stop portion 23 as a support point can resist these torques, reduce the bending or deformation of the rotating wheel set 21, and thereby provide stability.

[0060] Further, with reference to the drawings, Figures 4 to 6The stop portion 23 comprises a first stop ring 231 and a second stop ring 232 abutting against each other. The first stop ring 231 is protruded from the first side surface 211 and arranged around the first transmission shaft 22. The second stop ring 232 is protruded from the second side surface 212 and arranged around the first transmission shaft 22.

[0061] In the present embodiment, the first transmission shaft 22 is the central axis of the rotation of the rotation wheel set 21, and has a fixed position and stable structural support. The first stop ring 231 and the second stop ring 232 are arranged around the first transmission shaft 22. The first stop ring 231 and the second stop ring 232 can be arranged in close proximity to the first transmission shaft 22, or can be arranged at intervals from the first transmission shaft 22. This helps to maintain the coaxiality of the rotation wheel set 21, thereby providing continuous limiting action for the protruding portion 213, and thereby ensuring the stability of power transmission.

[0062] Compared with a single stop portion 23, the first stop ring 231 and the second stop ring 232 are arranged in a relatively symmetrical position, which can more flexibly allocate mechanical properties, while avoiding complex component design, and is conducive to simplifying the manufacturing process, improving production efficiency and reducing manufacturing costs.

[0063] Further, with reference to Figures 4 to 11 The rotation wheel set 21 has an axial hole 24 arranged therethrough, and the first transmission shaft 22 is inserted into the axial hole 24. The hole wall of the axial hole 24 is protruded to form the first stop ring 231 or the second stop ring 232.

[0064] The area around the axial hole 24 is usually the area where the rotation wheel set 21 is subjected to relatively concentrated force, especially when transmitting torque and bearing the pulling force of the doll weight applied through the hanging rope 50. In the present embodiment, the first stop ring 231 or the second stop ring 232 is protruded from the hole wall of the axial hole 24, which is equivalent to increasing the additional structural strength at this key position of the axial hole 24. The present embodiment shares the force around the axial hole 24 by the stop ring, reduces the risk of deformation or damage at the axial hole 24 due to excessive local force, and improves the overall structural strength and stability of the rotation wheel set 21.

[0065] If the first stop ring 231 and the second stop ring 232 are far away from the shaft hole 24, the force arm is longer, according to the principle of moment balance, in order to balance the moment generated by the external force (such as the non-uniform force generated by the offset of the doll's center of gravity, the impact force generated by the machine vibration, etc.), the contact pressure between the first stop ring 231 and the second stop ring 232 increases accordingly, so that the friction force of the first stop ring 231 and the second stop ring 232 increases. At this time, if the motor 11 cannot provide more power to maintain the normal operation of the rotating wheel set 21, the rotating wheel set 21 will appear the fault of being stuck. Moreover, the larger friction force will accelerate the wear of the first stop ring 231 and the second stop ring 232, and reduce the service life. On the contrary, in the embodiment, the stop ring and the shaft hole 24 are integrated, at this time, the force arm is shorter, the contact pressure between the first stop ring 231 and the second stop ring 232 is relatively small, so that the friction force of the first stop ring 231 and the second stop ring 232 is also relatively small.

[0066] At the same time, the integrated design of the stop ring and the shaft hole 24 enhances the stability of the stop ring in the rotating wheel set 21, so that the limiting effect on the convex part 213 is more reliable. In addition, the cooperation between the first stop ring 231 or the second stop ring 232 and the first transmission shaft 22 is more close, the relative sliding or shaking caused by the rotation of the transmission shaft is reduced, so that the power can be more stably transmitted to the rotating wheel set 21 through the transmission shaft.

[0067] In an embodiment, referring to Figures 5 to 11 , the rotating wheel set 21 comprises a first wheel body 214 and a second wheel body 215 arranged at intervals; the first wheel body 214 is provided with a first clamping fitting part 2141, and the second wheel body 215 is provided with a second clamping fitting part 2151 matched with the first clamping fitting part 2141; the first transmission shaft 22 penetrates through the first wheel body 214 and the second wheel body 215.

[0068] In the embodiment, the first wheel body 214 and the second wheel body 215 arranged at intervals provide sufficient space for the rope 50 to wind and release. The first wheel body 214 and the second wheel body 215 are stably connected through the first clamping fitting part 2141 and the second clamping fitting part 2151, and can work synchronously during operation; at the same time, the relative sliding between the rotating wheel bodies is reduced, so as to reduce the friction and wear, and prolong the service life of the rotating wheel set 21.

[0069] Further, referring to Figure 7 , Figure 8 and Figure 10The first wheel body 214 has a boss 2143 facing the second wheel body 215, and the outer circumferential surface of the boss 2143 is used to wind the hanging rope 50; the first transmission shaft 22 penetrates the boss 2143; the first clamping fitting part 2141 comprises at least two mounting holes 2142 which are arranged at intervals around the first transmission shaft 22; and the second clamping fitting part 2151 comprises at least two clamping hooks 2152 which are in one-to-one correspondence with the hole walls of the mounting holes 2142.

[0070] In the embodiment, the outer circumferential surface of the boss 2143 forms an effective winding surface which can be used to drive the hanging rope 50 to wind on the wheel body. The one-to-one interlocking mode of the mounting holes 2142 and the clamping hooks 2152 can ensure that the connection between the first wheel body 214 and the second wheel body 215 is stable and reliable. In this way, the loosening or misalignment of components caused by external force can be effectively prevented, thereby increasing the stability and anti-interference ability of the entire system.

[0071] Further, referring to Figure 5 , Figure 6 and Figure 9 , the clamping hooks 2152 are lower than or flush with the side of the first wheel body 214 away from the second wheel body 215. In this way, the risk of friction or collision between the clamping hooks 2152 and other components during high-speed rotation or operation can be avoided, thereby reducing the risk of wear or damage. At the same time, by preventing the clamping hooks 2152 from being exposed or excessively protruding, the accidental loosening of the clamping hooks 2152 can be avoided.

[0072] In an embodiment, referring to Figure 10 and Figure 11 , the mounting holes 2142 and the protrusions 213 are arranged at intervals in the circumferential direction of the first wheel body 214, and the mounting holes 2142 are located on the side of the protrusions 213 close to the first transmission shaft 22.

[0073] In the embodiment, the reasonable arrangement of the positions of the mounting holes 2142 and the protrusions 213 makes full use of the space of the first wheel body 214. Different functional structures are distributed at different positions, so that the first wheel body 214 can not only meet the space required for the protrusions 213 to perform power transmission and other operations, but also reserve appropriate mounting space for the mounting holes 2142 and the related components connected thereto, thereby avoiding excessive crowding of space and facilitating the compact layout of the internal structure of the lifting device 100 of the grab toy machine, and improving the space utilization rate.

[0074] In an embodiment, the first wheel body 214 is provided with a first recess 60, the second wheel body 215 is provided with a second recess 61, the first recess 60 and the second recess 61 are oppositely arranged, and the lifting device 100 of the grab toy machine further comprises a hanging rope 50, the hanging rope 50 comprises a rope body and a plurality of balls arranged in sequence on the rope body, and a part of one of the balls is arranged in the first recess 60 and another part of the ball is arranged in the second recess 61.

[0075] The lifting device 100 of the grab toy machine comprises a first shell 63 and a second shell 64, the first shell 63 and the second shell 64 are spliced along the axial direction of the first transmission shaft 22 to form a cavity, the driving assembly 10 and the driven assembly 20 are both arranged in the cavity, and the two sides of the driven assembly 20 abut against the inner wall surface of the cavity, so that the ball is clamped between the first groove 60 and the second groove 61 and can rotate along the circumferential direction of the first transmission shaft 22.

[0076] In the embodiment, the first groove 60 and the second groove 61 arranged oppositely provide a space for the ball. When the first clamping part 2141 and the first clamping part 2151 are clamped, the first groove 60 and the second groove 61 reinforce the ball, so that one end of the hanging rope 50 is relatively fixed. During the use of the grab toy machine, the first wheel body 214 and the second wheel body 215 may be affected by vibration or external force, causing the first clamping part 2141 and the first clamping part 2151 to be loosened, and then causing the ball to be unable to be clamped. In the embodiment, the two sides of the driven assembly 20 abut against the inner wall surface of the first shell 63 and the second shell 64 respectively. In this way, the ball can be stably clamped between the first groove 60 and the second groove 61, avoiding the ball from being separated or displaced in an unexpected direction, and ensuring the stability of the cooperation between the ball and the first groove 60 and the second groove 61.

[0077] In an embodiment, referring to Figure 1 and Figure 2 , the driving assembly 10 comprises a motor 11 and a longitudinal transmission shaft 12; the longitudinal transmission shaft 12 is in transmission connection with the motor 11 and the driven assembly 20 respectively, and the motor 11 and the driven assembly 20 are located on the two sides of the longitudinal transmission shaft 12 in the axial direction respectively; the motor shaft of the motor 11, the first transmission shaft 22 and the longitudinal transmission shaft 12 intersect with each other.

[0078] In the embodiment, the positions of the motor 11, the first transmission shaft 22 and the longitudinal transmission shaft 12 make full use of the space inside the device, avoiding the disorderly stacking and space waste of the components, so that the internal structure of the entire grab toy machine 200 is more compact and orderly, which is conducive to reducing the overall volume of the device and facilitating the overall packaging and protection of the device.

[0079] In an embodiment, the driven assembly 20 further comprises a elastic damping member 65, the elastic damping member 65 is located at one end of the first transmission shaft 22 away from the driving assembly 10; the elastic damping member 65 comprises a sleeve 66; the outer side surface of the rotating wheel set 21 has a first protrusion 68 arranged around the first transmission shaft 22, the sleeve 66 is sleeved on the first protrusion 68, and the end surface of the sleeve 66 away from the rotating wheel set 21 is flush with or exceeds the end surface of the first protrusion 68 away from the rotating wheel set 21.

[0080] In the embodiment, when the driving assembly 10 drives one of the rotating wheel sets 21 to rotate, force will be transmitted through the transmission component (such as the first transmission shaft 22) to try to drive the other rotating wheel set 21 to rotate. However, the elastic damping member 65 will be elastically deformed to generate a resisting torque, which is opposite to the torque transmitted from the rotating wheel set 21 adjacent to the driving assembly 10, so that the two rotating wheel sets 21 cannot immediately start to rotate at the same speed, thereby facilitating the rotating wheel set 21 adjacent to the driving assembly 10 to be wound with the partial hanging rope in advance.

[0081] In an embodiment, the driven assembly 20 further comprises a friction member 70 and a gear 73 sleeved on the first transmission shaft 22; the gear 73 is provided with a mounting groove 74 at one end thereof facing the rotating wheel set 21; the friction member 70 comprises an axial segment 71 extending along the axial direction of the first transmission shaft 22; the outer side surface of the rotating wheel set 21 is provided with a second protrusion 69 surrounding the first transmission shaft 22, the axial segment 71 is sleeved on the outer periphery of the second protrusion 69 and clamped between the outer peripheral wall of the second protrusion 69 and the circumferential side wall of the mounting groove 74, so as to frictionally connect the second protrusion 69 and the gear 73 in a clutching manner.

[0082] In the embodiment, the frictionally connecting the second protrusion 69 and the gear 73 in a clutching manner through the axial segment 71 means that the second protrusion 69, the gear 73 and the axial segment 71 integrally constitute a clutch-like structure. In this way, the second protrusion 69 and the gear 73 can directly realize the function of the friction clutch through friction. That is, the gear 73 is linked with the second protrusion 69 (the rotating wheel set 21) through the axial segment 71.

[0083] The axial segment 71 is clamped between the outer peripheral wall of the second protrusion 69 and the circumferential side wall of the mounting groove 74, which effectively increases the friction contact area of the second protrusion 69 and the gear 73 in the circumferential direction, so that the gear 73 and the second protrusion 69 will not be detached or excessively displaced in the axial direction. The friction member 70 can be made of elastic materials such as rubber and silica gel, or composite fiber materials, paper-based materials, etc., as long as it can realize the friction clutching of the second protrusion 69 and the gear 73, and the material of the friction member 70 is not specifically limited herein.

[0084] Further, the friction member 70 further comprises a radial segment 72 connected with the axial segment 71 and extending along the radial direction of the axial segment 71, the radial segment 72 is clamped between the outer side surface of the rotating wheel set 21 and the side surface of the gear 73 facing the rotating wheel set, and covers the slot of the mounting groove 74.

[0085] In the embodiment, the radial segment 72 covers the slot of the installation slot 74, so that the lubricating oil on the second protrusion 69 or the gear 73 cannot enter the installation slot 74, and the frictional combination between the axial segment 71 and the second protrusion 69 or the gear 73 is not affected. In addition, the radial segment 72 clamped between the second protrusion 69 and the gear 73 can also increase the friction area between the second protrusion 69 and the gear 73, so as to further improve the frictional combination fastening of the second protrusion 69 and the gear 73.

[0086] In an embodiment, the friction piece 70 is made of an elastic material. Specifically, the friction piece 70 can be made of an elastic material such as rubber, silica gel, etc. By making the friction piece 70 of an elastic material, the accuracy requirement of the axial segment 71 of the friction piece 70 is lower than that of a rigid material. Since the speed of the lifting device 100 of the grab toy machine is relatively slow, the friction piece 70 made of an elastic material can provide sufficient frictional combination force for the gear 73 and the second protrusion 69, so that the gear can drive the second protrusion 69 (the rotating wheel set 21) to rotate through the linkage of the axial segment 71. When the gear 73 is stopped by external resistance, the friction piece 70 made of an elastic material is also more convenient to realize the idling of the second protrusion 69 relative to the gear 73.

[0087] The utility model also proposes a kind of grab toy machine 200, referring to Figure 1 And Figure 2 The grab toy machine 200 further includes main body 30, clamp jaw 40, hanging rope 50 and the lifting device 100 of the above embodiment grab toy machine.
