Description

Technical Field

[0001] This invention relates to the field of children's educational toys, specifically to a mechanical transmission toy and its transmission mechanism. Background Technology

[0002] Children's educational toys are play tools designed to promote children's cognitive, social and physical development. In actual use, children's educational toys usually feature multi-person interactive play. Especially when playing in groups, children generally tend to place multiple toy parts on the transmission mechanism and engage in interactive games such as chasing and cooperating by moving the toy parts, thereby enhancing the fun of play and social experience. However, the transmission mechanisms of existing children's educational toys have significant structural limitations. Their transmission methods are mostly single unidirectional drive designs, which can only drive multiple toy parts to move in the same direction.

[0003] This single transmission mode cannot meet the diverse play needs in multi-person interactive scenarios. Specifically, it cannot flexibly switch multiple toy parts from moving in the same direction to moving in opposite directions or converging in opposite directions, resulting in rigid and monotonous interactive gameplay. It is difficult to stimulate children's desire to explore and their collaborative and innovative thinking. For example, it cannot realize fun interactive scenarios such as "toy chasing" and "two-way docking", which greatly reduces the sense of participation and fun when playing with multiple people. It not only limits the upper limit of the interactive experience of toys, but also weakens the core educational value of educational toys in cultivating children's collaborative ability through social interaction. It cannot fully adapt to the dynamic and ever-changing needs of children playing together. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 Reference Figures 1-5 A mechanical transmission toy transmission mechanism includes two mounting plates 1.

[0020] The transmission mechanism is mounted on two mounting plates 1. The transmission mechanism includes two first rods 2 fixedly connected to the side walls of the two mounting plates 1. Each of the two first rods 2 has two first wheels 3 rotatably connected to its side wall. The four first wheels 3 are opposite each other in pairs. A first sawtooth transmission belt 4 connects the two opposite first wheels 3. Two second rods 5 are fixedly connected to the side walls of the two mounting plates 1. Each of the two second rods 5 has two second wheels 6 rotatably connected to its side wall. The four second wheels 6 are opposite each other in pairs. A second sawtooth transmission belt 7 connects the two opposite second wheels 6. The two first sawtooth transmission belts 4 and the two second sawtooth transmission belts 7 are staggered. One of the second rods 5 has two first gears 8 rotatably connected to its side wall. The side walls of the two first gears 8 mesh with the side walls of the two first sawtooth transmission belts 4 respectively. The side wall of the first rod 2 away from the first gears 8 has two second gears 9 rotatably connected to its side wall. The side walls of the two second gears 9 mesh with the side walls of the two second sawtooth transmission belts 7 respectively.

[0021] Two mounting plates 1 have two cross shafts 10 rotatably connected through their side walls. One cross shaft 10 has a third gear 11 fixedly connected to its side wall, and the side wall of the third gear 11 meshes with the side walls of the two first gears 8. The other cross shaft 10 has a fourth gear 12 fixedly connected to its side wall, and the side wall of the fourth gear 12 meshes with the side walls of the two second gears 9.

[0022] Furthermore, an external joystick or paddle drive can be connected to the cross axis 10 to enhance the variety of gameplay.

[0023] Two first arc-shaped plates 14 are fixedly connected to the upper side wall of the two mounting plates 1, and two second arc-shaped plates 16 are fixedly connected to the lower side wall of the two mounting plates 1. A reinforcing plate 17 is fixedly connected to the middle of the side wall of the two mounting plates 1. The reinforcing plate 17 is located below the transmission mechanism. Protective plates 15 are fixedly connected to the side walls of the two mounting plates 1 that are far apart from each other. A base plate 18 is fixedly connected to the lower ends of the two second arc-shaped plates 16 and the two protective plates 15.

[0024] A mechanical transmission toy includes two toy seats 49, both of which have rectangular lower ends. One toy seat 49 engages with two first serrated transmission belts 4 at its lower end, and the other toy seat 49 engages with two second serrated transmission belts 7 at its lower end (e.g.,...). Figure 5 As shown), the toy body 50 is fixedly connected to the upper end of both toy seats 49.

[0025] When the child drives the third gear 11 to rotate clockwise via the cross shaft 10, the two first gears 8 rotate counterclockwise, causing the two first sawtooth transmission belts 4 to move to the right (as shown). Figure 5 As shown), when the child drives the third gear 11 to rotate counterclockwise via the cross shaft 10, the two first gears 8 rotate clockwise, causing the two first sawtooth transmission belts 4 to move to the left (as shown). Figure 5 (as shown) When the child drives the fourth gear 12 to rotate clockwise through the cross shaft 10, the two second gears 9 rotate counterclockwise, causing the two second sawtooth transmission belts 7 to move to the right. When the child drives the fourth gear 12 to rotate counterclockwise through the cross shaft 10, the two second gears 9 rotate clockwise, causing the two second sawtooth transmission belts 7 to move to the left. Thus, when the third gear 11 and the fourth gear 12 rotate clockwise or counterclockwise, the two first sawtooth transmission belts 4 and the two second sawtooth transmission belts 7 move to the right or to the left in the same direction, driving the two toy bodies 50 to move in the same direction through the two toy seats 49. When the third gear 11 rotates clockwise and the fourth gear 12 rotates counterclockwise, the two first sawtooth transmission belts 4 move to the right and the two second sawtooth transmission belts 7 move to the left, which in turn drive the two toy bodies 50 to move towards each other and collide through the two toy seats 49. When the third gear 11 rotates counterclockwise and the fourth gear 12 rotates clockwise, the two first sawtooth transmission belts 4 move to the left and the two second sawtooth transmission belts 7 move to the right, driving the two toy bodies 50 to move away from each other through the two toy seats 49. In summary, this transmission mechanism can control two toy bodies 50 to produce dynamic interactive behaviors such as collision, tug-of-war, and chasing, thereby increasing the interactive experience of educational toys. It avoids the limitations of existing technologies that cannot flexibly switch multiple trajectory modes such as reverse movement and convective movement of multiple toy parts on the basis of unidirectional movement, resulting in rigid and monotonous interactive gameplay that is difficult to stimulate children's desire for exploration and collaborative innovative thinking.

[0026] Example 2 Reference Figure 1 , Figures 6-8 It also includes a cleaning mechanism, which includes two fixed plates 19 fixedly connected to the upper ends of two mounting plates 1. The side walls of the two fixed plates 19 that are far apart from each other are fixedly connected to the side walls of two first arc-shaped plates 14. The side walls of the two mounting plates 1 located within the two fixed plates 19 are rotatably connected to a reciprocating screw 21. The side wall of the reciprocating screw 21 is threadedly connected to a threaded plate 22. The upper end of the threaded plate 22 is slidably connected to the lower end of its corresponding fixed plate 19. The lower end of the threaded plate 22 is fixedly connected to a plurality of bristles 23. The side walls of the plurality of bristles 23 are respectively attached to the upper ends of two first sawtooth transmission belts 4 and two second sawtooth transmission belts 7.

[0027] Both mounting plates 1 have openings 20 on their side walls that correspond to the two threaded plates 22 (e.g., Figure 6 As shown, the impurities swept off the two first sawtooth drive belts 4 and the two second sawtooth drive belts 7 are discharged. Large synchronous pulleys 24 are fixedly connected to the side walls of the two cross shafts 10 outside the mounting plate 1, and small synchronous pulleys 25 are fixedly connected to the side walls of the two reciprocating screws 21 outside the mounting plate 1. A synchronous belt connects the large synchronous pulleys 24 and their corresponding small synchronous pulleys 25, so that when the large synchronous pulley 24 rotates once, the small synchronous pulley 25 can rotate multiple times, causing the reciprocating screw 21 to rotate multiple times, driving the threaded plate 22 to move back and forth multiple times, thereby cleaning the impurities on the two first sawtooth drive belts 4 and the two second sawtooth drive belts 7.

[0028] When the cross shaft 10 rotates, the reciprocating screw 21 rotates via the large synchronous pulley 24, the synchronous belt, and the small synchronous pulley 25, causing the threaded plate 22 to move back and forth on the lower surface of the fixed plate 19. This allows multiple bristles 23 to clean impurities from the two first sawtooth transmission belts 4 and the two second sawtooth transmission belts 7, preventing impurities on their surfaces from entering the meshing points between the first gear 8 and the two first sawtooth transmission belts 4, and between the second gear 9 and the two second sawtooth transmission belts 7 during their movement, thus avoiding any obstruction to the transmission.

[0029] Example 3 Reference Figures 8-13 Both first arc-shaped plates 14 have annular frames 26 fixedly connected through their side walls. Sliding frames 27 are attached to the inner walls of the two annular frames 26. Lubricant plates 28 are fixedly connected to the inner walls of the two sliding frames 27. One lubricant plate 28 is directly opposite the third gear 11, and the other lubricant plate 28 is directly opposite the fourth gear 12.

[0030] Furthermore, the lubricant plate 28 uses a rod-shaped solid lubricant made of polytetrafluoroethylene or molybdenum disulfide to avoid corrosion of other non-transmission parts caused by the use of liquid lubricants, while also meeting hygiene requirements.

[0031] Two self-feeding mechanisms are fixedly connected to the side wall of one of the protective plates 15. The two self-feeding mechanisms include two fixed frames 29 fixedly connected to the side wall of one of the protective plates 15. The two fixed frames 29 correspond one-to-one with two annular frames 26. The inner walls of the two fixed frames 29 are sealed and slidably connected with wedge plates 30. The side walls of the two wedge plates 30 that are far apart from each other are fixedly connected with U-shaped rods 51. The side walls of the two sliding frames 27 that are close to each other are fixedly connected with L-shaped rods 13. The side wall of the L-shaped rod 13 is connected to the side wall of its corresponding U-shaped rod 51 by bolts. The L-shaped rod 13 and the U-shaped rod 51 can be disassembled to facilitate the replacement of the lubricant plate 28.

[0032] Both fixed frames 29 have multiple opposing adjustable frames 31 (such as...) that are fixedly connected through their top and bottom edges. Figure 11 and Figure 12 As shown), wedge-shaped rods 32 are slidably connected to the inner walls of multiple adjustment frames 31. Strip-shaped cavities 33 are opened on the inner walls of multiple adjustment frames 31 away from the wedge-shaped rods 32. First plates 34 are slidably connected to the inner walls of multiple strip-shaped cavities 33. Connecting rods 35 are fixedly connected between the first plate 34 and the side wall of its corresponding wedge-shaped rod 32. The side wall of the connecting rod 35 is slidably connected to the side wall of the adjustment frame 31. The side wall of the first plate 34 away from the connecting rod 35 is elastically connected to the inner wall of the strip-shaped cavity 33 through multiple springs 36. Furthermore, through holes are opened on the inner wall of the strip-shaped cavity 33 near the springs 36 to balance the pressure change in the strip-shaped cavity 33 when the first plate 34 slides.

[0033] The inner wall of the fixed frame 29 is fixedly connected to two first pipes 37. The inner walls of two strip cavities 33 located near the inner wall of the fixed frame 29 and at the top and bottom are fixedly connected to the pipe openings of the two first pipes 37 away from the fixed frame 29. A first pressure valve 38 is installed in each of the two first pipes 37. A second pipe 39 is fixedly connected between the inner walls of two adjacent strip cavities 33. A second pressure valve 40 is installed in the inner walls of multiple second pipes 39. A first pressure relief pipe 41 is fixedly connected to the inner wall of the fixed frame 29. A second pressure relief pipe 42 is fixedly connected to the inner walls of multiple strip cavities 33.

[0034] It should be noted that the pressure set values ​​on the multiple second pressure valves 40 from right to left increase sequentially (e.g., Figure 11 and Figure 12 As shown in the figure, both the first pressure relief pipe 41 and the second pressure relief pipe 42 are equipped with plugs for opening and closing.

[0035] Two air pump frames 43 are fixedly connected to the side wall of the mounting plate 1 near the fixed frame 29. The inner walls of the two air pump frames 43 are slidably connected to a second plate 44. The inner walls of the two air pump frames 43 are fixedly connected to a one-way suction pipe 47. The inner walls of the two air pump frames 43 are fixedly connected to the inner walls of the two fixed frames 29 through one-way exhaust pipes 48. The side walls of the two cross shafts 10 away from the large synchronous wheel 24 are fixedly connected to a fixed plate 45. The side walls of the fixed plate 45 away from the axis are rotatably connected to the side walls of the corresponding second plate 44 through a rotating rod 46.

[0036] It should be noted that the one-way suction pipe 47 only allows gas to enter the pumping frame 43 from the outside, and the one-way discharge pipe 48 only allows gas to enter the fixed frame 29 from the pumping frame 43. This can be achieved through a one-way valve.

[0037] During the rotation of the cross shaft 10, the second plate 44 will slide back and forth on the inner wall of the pump frame 43 through the fixed plate 45 and the rotating rod 46. Gas is intermittently pumped into the fixed frame 29 through the one-way suction pipe 47 and the one-way exhaust pipe 48, which makes the pressure in the fixed frame 29 continuously increase, while the wedge plate 30 cannot move due to the obstruction of the two wedge rods 32. As the pressure inside the fixed frame 29 continuously increases, the set value of the first pressure valve 38 is opened. At this time, the first pressure valve 38 opens, allowing gas from the fixed frame 29 to flow through the two first pipes 37 into the two strip-shaped cavities 33 connected to the two first pipes 37. This causes the pressure in the two strip-shaped cavities 33 to increase intermittently. As more gas enters the two strip-shaped cavities 33, the gas pressure overcomes the elastic force of the multiple springs 36, causing the two first plates 34 to move away from each other. Through the two connecting rods 35, the two wedge-shaped rods 32 move away from each other until they separate from the wedge-shaped plate 30. Subsequently, the wedge-shaped plate 30 moves to the left under the action of the gas pressure inside the fixed frame 29 (e.g., ...). Figure 12 (As shown), the sidewall of the wedge plate 30 will then fit against the sidewalls of the next two wedge rods 32; Subsequently, gas continues to accumulate in the new fixed frame 29 formed during the movement of the wedge plate 30. Then, the gas enters the strip cavity 33 corresponding to the wedge rod 32 that is in contact with the wedge plate 30 through the first pressure valve 38 and the first second pressure valve 40 on the right. The above steps will be repeated, so that the wedge plate 30 will move to the left intermittently at relatively long intervals. When the wedge plate 30 moves intermittently to the left, the sliding frame 27 is driven to move closer to the cross shaft 10 by the U-shaped rod 51 and the L-shaped rod 13, so that the two lubricant plates 28 are close to the third gear 11 and the fourth gear 12 respectively. This allows the third gear 11 and the fourth gear 12 to scrape off the solid lubricant on the two lubricant plates 28 during rotation, thereby increasing the smoothness of transmission between the gears in the transmission mechanism and increasing the stability of the transmission mechanism during use. After the lubricant plate 28 is used up, the self-feeding mechanism needs to be reset to its initial position. At this time, the gas in the fixed frame 29 and the multiple strip cavities 33 is discharged through the first pressure relief pipe 41 and multiple second pressure relief pipes 42 respectively, so that the multiple wedge rods 32 are in their initial positions (e.g., Figure 12 As shown), the worker can then press the wedge plate 30 to the right. At this time, the wedge plate 30 will continuously pass over multiple wedge rods 32 and return to the initial position. Then, the first pressure relief pipe 41 and multiple second pressure relief pipes 42 can be closed by using the plug cap. Then, after the lubricant plate 28 is replaced, the transmission mechanism can be lubricated again.

[0038] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
