[0096] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0097] See attached document Figure 1-56 An assembly robot toy according to an embodiment of the present invention.

[0098] See attached document Figure 1 and attached Figure 9The assembled robot toy includes a gearbox 2, a head component 1 detachably mounted on the gearbox 2, and an assembly component 3. The gearbox 2 contains a gear set 200, a motor 26 connected to the gear set 200, and multiple transmission rods 21. First clearance holes 222 are provided on the left and right side walls of the gearbox 2, and a second clearance hole 277 is provided on the bottom of the gearbox 2 corresponding to the position of the gear set 200. At least two transmission rods 21 pass through the first clearance holes 222 on the left and right side walls of the gearbox 2 and are positioned outside the gearbox 2. Alternatively, at least two transmission rods 21 are positioned close to the first clearance holes 222 on the left and right side walls of the gearbox 2. The assembly component 3 is connected to the gear set 200 and / or the transmission rods 21. The head component 1 is equipped with a power supply module 11 electrically connected to the motor 26 and used to supply power to the motor 26. The transmission rod 21 is configured to rotate via the gear set 200 when driven by the motor 26, and at least part of the assembly assembly 3 is configured to move and drive the gear box 2 when the gear set 200 and / or the transmission rod 21 rotate.

[0099] This embodiment provides two transmission rods 21 on both sides of the gear box 2 and a second clearance hole 277 at the bottom of the gear box 2 corresponding to the gear set 200. This allows the gear box 2 to have power output on both sides and the bottom, so that the assembly components 3 can be connected and used. This breaks the problem that conventional electric toys with dual-end or symmetrical power outputs have limited assembly diversity. This embodiment improves the assembly diversity of the robot toy, stimulates children's imagination and creativity in assembly, and increases the fun of the toy.

[0100] In one embodiment, reference is made to the appendix. Figure 8-11 The gear set 200 includes: a first rotating rod 28, a first spur gear 25 mounted on the shaft of the motor 26, a first face gear 24 passing through the first rotating rod 28 and meshing with the first spur gear 25, and a second spur gear 23 passing through the first rotating rod 28 and used for connection with the assembly assembly 3. There are two transmission rods 21, respectively located at both ends of the first rotating rod 28. When the motor 26 drives the first spur gear 25 to rotate, the first rotating rod 28 rotates via the first face gear 24, thereby driving the second spur gear 23 and the transmission rods 21 to rotate. Thus, when the motor 26 drives, it drives the first spur gear 25 to rotate, which in turn allows the first rotating rod 28 to rotate via the first face gear 24, driving the second spur gear 23 and the two transmission rods 21 to rotate, achieving power output from both sides and the bottom of the gearbox 2.

[0101] Specifically, in the above embodiment, to achieve a compact gear set 200, the second spur gear 23 includes: spur gear one 237, spur gear two 234, spur gear three 233, and spur gear four 232 sequentially mounted on the first rotating rod 28, and spur gear five 236 and spur gear six 235 rotatably mounted in the gear box 2. Spur gear one 237 meshes with spur gear five 236, spur gear six 235 meshes with spur gear two 234, and spur gear three 233 and spur gear four 232 are both used to connect with the assembly component 3. Thus, when the first rotating rod 28 rotates, it can drive spur gear one 237, spur gear two 234, spur gear three 233, and spur gear four 232 to rotate together. The first injection molded part is integrally formed with the first face gear 24, the second injection molded part is integrally formed with the fifth injection molded part and the sixth injection molded part is integrally formed with the sixth injection molded part, and the third injection molded part is integrally formed with the third injection molded part, the fourth injection molded part and the transmission rod 21. This prevents the gear set 200 from having too many parts and makes it easier to find if they are lost. In addition, the first injection molded part and the second injection molded part are also meshed with the third injection molded part, which can improve the stability of the gear set 200. The two transmission rods 21 pass through the first clearance holes 222 on the left and right side walls of the gear box 2 respectively and are placed on the outside of the gear box 2 to facilitate the assembly and connection of the assembly component 3.

[0102] Of course, in other embodiments, the second spur gear 23 may not include one or more of spur gears 236, 235, 237, 234, 233, and 232. The number of gears can be limited according to the needs of the customer and the requirements for stability. Therefore, the number of spur gears included in the second spur gear 23 is not limited here. Furthermore, it should be noted that the number of second spur gears 23 can be one or more, and the number of second spur gears 23 is not limited here either.

[0103] In one embodiment, the gearbox 2 includes a first housing 22 and a second housing 27 detachably connected to the first housing 22 to form a first mounting cavity 273, a second mounting cavity 272, and a second clearance hole 277. A motor 26 is mounted in the first mounting cavity 273, and a gear set 200 is mounted in the second mounting cavity 272. The first housing 22 and / or the second housing 27 have wiring holes 276 communicating with the first mounting cavity 273. The first housing 22 and the second housing 27 are detachable, allowing users to easily install the gear set 200, motor 26, and transmission rod 21 within the first housing 22 and the second housing 27 to complete the assembly of the entire gearbox 2. Users can also understand the mechanical principles of how the motor 26 drives the gear set 200 and transmission rod 21, expanding their knowledge. Furthermore, the wiring holes 276 facilitate the routing of wires connecting the power supply module 11 in the head component 1 to the motor 26, thus electrically connecting the motor 26 and the power supply module 11.

[0104] In the above embodiment, a rotating hole 2741 is provided on the second mounting cavity 272. The gear set 200 also includes: a second rotating rod 274, one end of which passes through spur gear five 236 and spur gear six 235 and is placed in the rotating hole 2741, and a limiting cap 29 provided at the other end of the second rotating rod 274. Spur gear three 233 is located between spur gear five 236 and limiting cap 29. Therefore, when assembling the robot toy in this embodiment, one end of the second rotating rod 274 can be placed in the rotating hole 2741 and the motor 26 can be placed in the first mounting cavity 273. Then, the independent transmission rod 21 can be placed in the first clearance hole 222. Then, one end of the first rotating rod 28 can be inserted into the middle of the transmission rod 21. Then, the first injection molded part can be sleeved on the first rotating rod 28, the third injection molded part can be sleeved on the second rotating rod 274, and the spur gear two 234 can be sleeved on the second rotating rod 2741. On a rotating rod 28, a limiting cap 29 is inserted into the end of a second rotating rod 274 away from the rotating hole 2741. A second injection molded part is fitted onto the first rotating rod 28. The first face gear 24, spur gear five 236, spur gear two 234 and the limiting cap 29 mutually limit each other, thus limiting the second rotating rod 274 within the rotating hole 2741. When the first housing 22 is connected to the second housing 27, the two transmission rods 21 are placed after passing through the second clearance hole 277, completely limiting the entire gear set 200 and the motor 26, thus realizing the installation of the gear box 2.

[0105] In one embodiment, reference is made to the appendix. Figure 13 The first housing 22 has a plurality of first insertion ends 221 protruding on the side opposite to the second housing 27. The second housing 27 has a plurality of first insertion slots 271 on the side opposite to the first housing 22. The first insertion ends 221 are placed in the first insertion slots 271 to connect the first housing 22 and the second housing 27. The gear box 2 also includes a plurality of reinforcing cover plates 20. The reinforcing cover plates 20 have a plurality of first snap holes 201. Both sides of the first housing 22 and the second housing 27 are provided with a plurality of first buckles 275. The first buckles 275 engage with the first snap holes 201 to fix the reinforcing cover plates 20 to the first housing 22 and the second housing 27. The reinforcing cover plates 20 can strengthen the connection between the first housing 22 and the second housing 27 and prevent the first housing 22 and the second housing 27 from separating. In this embodiment, the first housing 22 and the second housing 27 are connected in the left and right directions. A gearbox 2 has two reinforcing cover plates 20, located on the front and rear sides of the gearbox 2. In other embodiments, a gearbox 2 may have four reinforcing cover plates 20, located on the four side walls of the gearbox 2, etc.

[0106] In other embodiments, the first housing 22 can also be detachably connected to the second housing 27 by means of snap-fit ​​or screws, and the connection method between the first housing 22 and the second housing 27 is not limited here.

[0107] In one embodiment, reference is made to the appendix. Figure 1 The head component 1 is rotatably connected to the gear box 2. The head component 1 is located at one of the top, front, or back positions of the gear box 2, thereby increasing the diversity of the assembly position of the head component 1. Furthermore, the user can adjust the position of the head component 1 according to the assembled assembly components 3, thereby increasing the user's creativity in assembling the toy.

[0108] In the above embodiments, refer to the appendix. Figure 4 A first connecting rod 6 and a second connecting rod 5 are provided between the head component 1 and the gear box 2, and the first connecting rod 6 and the second connecting rod 5 are rotatably connected. The first connecting rod 6 is configured to drive the head component 1 to rotate along the central axis of the first connecting rod 6 under the action of an external force, and the second connecting rod 5 is configured to drive the head component 1 to rotate in a direction perpendicular to the central axis of the first connecting rod 6 under the action of an external force. For example, when the head component 1 is installed on the top surface of the gear box 2, the first connecting rod 6 can make the head component 1 rotate along the Z-axis, and the second connecting rod 5 can make the head component 1 rotate along the X-axis. For example, when the head component 1 is installed on the front side wall of the gear box 2, the first connecting rod 6 can make the head component 1 rotate along the Y-axis, and the second connecting rod 5 can make the head component 1 rotate along the X-axis, so as to increase the angle between the head component 1 and the gear box 2 and enhance the fun of assembling the robot toy in this embodiment.

[0109] It should be noted that the Z-axis refers to the upper and lower ends of gear box 2, the X-axis refers to the front and rear directions of gear box 2, and the Y-axis refers to the left and right directions of gear box 2.

[0110] For details, please refer to the appendix. Figure 4 The first connecting rod 6 includes: a first limiting plate 62, a fourth locking block 64 disposed at the bottom of the first limiting plate 62, and a third ear seat 61 disposed at the top of the first limiting plate 62. The third ear seat 61 has protrusions on both sides forming a first rotating part 65. The fourth locking block 64 is cylindrical, and its circumferential bottom protrusion forms an annular locking block 63. The bottom of the head component 1 has a protrusion forming a fourth ear seat 141, and the two sides of the fourth ear seat 141 have protrusions forming a second rotating part 142. Head mounting holes 278 are provided at the center of the front, rear, and top surfaces of the gear box 2. The second connecting rod 5 includes a left connecting rod 52 and a right connecting rod 51. Shaft holes 53 are provided at both the upper and lower ends of the left connecting rod 52 and the right connecting rod. The fourth locking block 64 is inserted into the head mounting hole 278, and the annular locking block 63 and the first limiting plate 62 are limited at both ends of the head mounting hole 278, realizing the rotatable connection between the first connecting rod 6 and the gear box 2. The shaft holes 53 at the upper and lower ends of the left connecting rod 52 and the right connecting rod are respectively fitted onto the second rotating part 142 and the first rotating part 65. The head component 1 is connected to the first connecting rod 6 through the second connecting rod 5, and the head component 1 can be rotated in a direction perpendicular to the central axis of the first connecting rod 6 under the action of external force, so that the user can easily adjust the rotation angle of the head component 1.

[0111] Of course, in other embodiments, the head component 1 can also be connected to the gear box 2 in sequence via the first connecting rod 6 and the second connecting rod 5, that is, the head mounting hole 278 is opened at the bottom of the head component 1, and the second locking block 3212 of the first connecting rod 6 is inserted into the bottom of the head component 1. The fourth ear seat 141 is provided on the gear box 2, and the first connecting rod 6 and the gear box 2 are connected via the second connecting rod 5, so that the gear box 2 can rotate in multiple directions. The positional relationship and structure of the first connecting rod 6 and the second connecting rod 5 are not limited here. For example, the second connecting rod 5 may only include the left connecting rod 52, etc.

[0112] In one embodiment, the power supply module 11 is a solar panel, so that when the user places the assembled robot toy of this embodiment under sunlight, it can drive the gear box 2 and the head part 1 to move in conjunction with the assembly component 3.

[0113] Specifically, in this embodiment, refer to the appendix. Figure 5-7 The head component 1 includes: a bottom shell 14; a front shell 17 detachably connected to the bottom shell 14 and forming a third mounting cavity 144 and two fourth mounting cavities 145 with the bottom shell 14; and two conductive springs 16 respectively disposed in the two fourth mounting cavities 145. The two fourth mounting cavities 145 are spaced apart and are both connected to the third mounting cavity 144. The front shell 17 and / or the bottom shell 14 have third clearance holes 145 at positions corresponding to the fourth mounting cavities 145. The solar panel is disposed in the third mounting cavity 144, and the front shell 17 has a display port 171 at the position corresponding to the solar panel to allow the solar panel to receive light energy. Two conductive wires 4 are electrically connected to the motor 26, and conductive plates 41 are provided at the ends of the conductive wires 4. The conductive plates 41 are inserted into the conductive springs 16. The third clearance holes 145 facilitate the insertion of the conductive plates 41 into the conductive springs 16, and the use of conductive plates 41 and conductive springs 16 facilitates user assembly and electrical connection of the solar panel and the motor 26.

[0114] In one embodiment, the conductive spring 16 is welded to the solar panel at the factory. One end of the faceplate 17 extends downward to form a second plug end 174, and the other end extends downward to form a plurality of spaced first stops 173. The first stops 173 have a second stop 172 protruding on the bottom side opposite to the second plug end 174.

[0115] The bottom shell 14 has a second insertion slot 147 with a length greater than that of the second insertion end 174. This allows the bottom shell 14 to be positioned above the second stop block 172 after the solar panel and conductive spring 16 are installed in the third mounting cavity 144 and the fourth mounting cavity 145, with the second insertion end 174 placed within the second insertion slot 147. The longer length of the second insertion slot 147 compared to the second insertion end 174 facilitates placement of the second insertion end 174 within the slot. The head component 1 also includes multiple covers 12 with receiving slots 121. The bottom shell 14 and the front shell 17 are connected to form first joint ends 13 on both sides of the bottom shell 14. The first joint ends 13 are placed within the receiving slots 121. The covers 12 improve the stability of the connection between the bottom shell 14 and the front shell 17.

[0116] It should be noted that the maximum power output of the solar panel from converting light energy into electrical energy does not exceed the maximum power that the motor 26 can withstand, to prevent damage to the motor 26 if the solar panel is directly connected to it. Although the voltage output of the solar panel is unstable in this way, it does not affect the driving of the motor 26. Of course, in order to ensure a stable output voltage from the solar panel, a circuit board can also be configured between the solar panel and the motor 26, wherein the circuit board is located inside the gear box 2 or the head component 1.

[0117] In other embodiments, the solar panel can be directly attached to the upper surface of the head component 1 or embedded in the upper surface of the head component 1, and the conductive sheet 41 and the conductive spring 16 can be replaced by connectors. The power supply module 11 can also be a battery. The bottom shell 14 and the front shell 17 can also be detachably connected by screws or buckles.

[0118] In this embodiment, two second cylinders 15 are formed at the bottom of the bottom shell 14. The two second cylinders 15 constitute the two eyes of the head component 1. The gear box 2 can be the robot body, which is used in conjunction with the assembly component 3 to form the robot.

[0119] In the above embodiments, refer to the appendix. Figure 14-36 Assembly component 3 includes multiple pins, a fixing plate 312, a connecting plate 313, a third rotating rod 302, a fixing rod 303, a first cam 306, a second cam 304, a wave gear 315, a third spur gear 311, a straight connecting rod 322, a lever arm connecting rod 301, an arc-shaped connecting rod 316, a T-shaped connecting rod 307, a symmetrical semi-circular part 308, a U-shaped part 309, and a wheel 314.

[0120] Any two of the following components—gearbox 2, fixing plate 312, connecting plate 313, straight connecting rod 322, arc-shaped connecting rod 316, T-shaped connecting rod 307, U-shaped part 309, lever arm connecting rod 301, symmetrical semi-circular part 308, first cam 306, second cam 304, and wheel 314—can be detachably connected via a pin or fixing rod 303. The third spur gear 311 can mesh with the second spur gear 23. The third spur gear 311, second cam 304, wave gear 315, and wheel 314 can also be detachably mounted on the third rotating rod 302 or fixing rod 303. The second cam 304 can be detachably inserted into the transmission rod 21. Thus, users can customize the assembly component 3 to assemble on the gearbox 2 according to their ideas, thereby realizing the assembly of the robot.

[0121] Specifically, the pin includes a rotating pin and a fixing pin. One end of the rotating pin, both ends of the fixing pin and the fixing rod 303 are polygonal prisms 330 and one end is a first cylinder 3191. The first cylinder 3191 has a third locking block 3192 protruding outward at the end away from the first polygonal prism 330.

[0122] Multiple first mounting holes 310 are provided on the side wall of gear box 2, fixing plate 312, connecting plate 313, straight connecting rod 322, arc connecting rod 316, T-shaped connecting rod 307, U-shaped part 309, lever arm connecting rod 301, symmetrical semicircular part 308, first cam 306, second cam 304, and wheel 314, which can be used to mate with polygonal column 330 and first cylinder 3191. This allows any two of the following components to be detachably connected via a rotating pin, a latch, or a fixing rod 303: gear box 2, fixing plate 312, connecting plate 313, straight connecting rod 322, arc connecting rod 316, T-shaped connecting rod 307, U-shaped part 309, lever arm connecting rod 301, symmetrical semicircular part 308, first cam 306, second cam 304, and wheel 314. The third spur gear 311, the second cam 304, and the wave gear 315 have a second mounting hole 320 in the middle for inserting into the fixing rod 303 and the third rotating rod 302, thereby enabling the third spur gear 311, the second cam 304, and the wave gear 315 to be sleeved on the fixing rod 303 and the third rotating rod 302. In addition to the first mounting hole 310, the first cam 306 also has a third mounting hole 340 in the middle for engaging with both ends of the third rotating rod 302.

[0123] The first mounting hole 310 and the third mounting hole 340 are both circular holes, with the diameter of the third mounting hole 340 slightly smaller than its diameter. The second mounting hole 320 is a polygonal hole, with the longest width of the polygonal cylinder 330 matching the diameter of the first mounting hole 310. The diameter of the first cylinder 3191 is slightly smaller than that of the first mounting hole 310, and the width of the third locking block 3192 is slightly larger than that of the first mounting hole 310. Thus, by having the polygonal cylinder 330 on the pin and the rotating pin pass through the first mounting holes 310 of the two components, the two components can be fixed together and difficult to rotate. By having the first cylinder 3191 on the rotating pin pass through the first mounting holes 310 of the two components, the two components can rotate relative to each other. Furthermore, if the first cylinder 3191 passes through the first mounting hole 310 of a component, that component can rotate along the first cylinder 3191.

[0124] The diameters of both ends of the third rotating rod 302 are smaller than the diameter of the first mounting hole 310 and fit the size of the third mounting hole 340. The assembly assembly 3 also includes a connector 305. One end of the connector 305 is provided with a third mounting hole 340 for inserting the two ends of the third rotating rod 302. One end of the connector 305 is also a polygonal prism 330 that fits the size of the first mounting hole 310. Thus, the third rotating rod 302 can still rotate after passing through the first mounting hole 310. The connector 305 is then used to connect components such as the wheel 314 and the second cam 304.

[0125] The T-shaped connecting rod 307 has a first sliding hole 3071 and a second sliding hole 3072 perpendicular to the first sliding hole 3071. The widths of the first sliding hole 3071 and the second sliding hole 3072 are the same as the diameter of the first mounting hole 310. The first cylinder 3191 of the rotating pin passes through the second sliding hole 3072 and the first sliding hole 3071, and is then engaged and limited by the third locking block 3192, so that the first cylinder 3191 of the rotating pin can move back and forth along the length of the second sliding hole 3072 and the first sliding hole 3071.

[0126] The wave gear 315 is provided with multiple arc-shaped teeth 3151 arranged around it. The wave gear 315 can be used for decoration or two adjacent arc-shaped teeth 3151 can accommodate one end of the straight connecting rod 322. The symmetrical semi-circular part 308 is formed by two semi-circular plates 3081 connected in a centrally symmetrical manner. The side wall of the second cam 304 is provided with first gear teeth 3041 arranged around it. The inner side of the arc-shaped connecting rod 316 is provided with second gear teeth 3161 for meshing with the second cam 304, so that users can assemble and use it.

[0127] In one embodiment, at least one flat surface is formed on the outer side wall of the third rotating rod 302, and the shape of the second mounting hole 320 is consistent with the outer side wall of the third rotating rod 302, so that when the third spur gear 311 and the second cam 304 are sleeved on the third rotating rod 302, the rotation of the third rotating rod 302 can drive the third spur gear 311 and the second cam 304 to move and rotate, or the rotation of the third spur gear 311 and the second cam 304 can drive the third rotating rod 302 to rotate.

[0128] Specifically, the cross-section of the outer wall of the third rotating rod 302 is hexagonal, pentagonal, octagonal, etc. The cross-section of the outer wall of the fixing rod 303 is circular, and the diameter of the fixing rod 303 is equal to the distance between two opposite sides of the hexagon, so that when the third spur gear 311 and the second cam 304 are sleeved on the fixing rod 303, the fixing rod 303 does not obstruct the rotation of the third spur gear 311 and the second cam 304, so as to facilitate user assembly and use.

[0129] In one embodiment, multiple annular slots 3021 are provided at equal intervals on the outer side walls of the fixed rod 303 and the third rotating rod 302. The assembly assembly 3 also includes multiple fixed sleeves 321 sleeved on the fixed rod 303 or the third rotating rod 302. At least one U-shaped opening 3211 is provided on the side wall of the fixed sleeve 321. One end of the inner side wall of the fixed sleeve 321 protrudes inward to form a second locking block 3212 that cooperates with the annular slots 3021. Furthermore, in order to fix the third spur gear 311 and the second cam 304 at the position of the fixed rod 303 or the third rotating rod 302, a fixing sleeve 321 can be respectively fitted on the third rotating rod 302 on both sides of the third gear and the second cam 304, and the second locking block 3212 can be engaged with the annular locking groove 3021 to fix the fixing sleeve 321 at the position of the third rotating rod 302, so as to limit the position of the third spur gear 311 and the second cam 304 on the fixed rod 303 or the third rotating rod 302.

[0130] In the above embodiments, refer to the appendix. Figure 37-54 The number of gear boxes 2 and head parts 1 can be multiple. With the help of assembly components 3, the shape of the assembled robot toy can be assembled into various forms such as children's car robot 1001, four-legged robot 1002, turtle robot 1003, puppy robot 1004, beetle robot 1005, walker robot 1006, crab robot 1007, short and fat robot 1008, crawling robot 1009, and zombie robot 1010.

[0131] Specifically, when the assembly robot toy is assembled into the children's car robot 1001, the parts required for the children's car robot 1001 and their positional relationships are as follows:

[0132] See attached document Figure 37 Appendix Figure 55 and attached Figure 56 There is one gearbox 2 and one head component 1, with the head component 1 mounted on the top of the gearbox 2. There are two fixing plates 312, detachably mounted on the left and right side walls of the gearbox 2 via pins. There are four connecting plates 313, with the front end of each fixing plate 312 connected to another connecting plate 313 via a connecting plate 313. Each fixing plate 312 and the two connecting plates 313 on the same side form a first long arm 3001. The connections between the fixing plates 312 and the connecting plates 313, as well as between the two connecting plates 313, are all via pins. There are two third rotating rods 302, located at the front and rear ends of the first long arm 3001 and at the bottom of the gearbox 2. There are four wheels 314, with each end of the third rotating rod 302 passing through two opposite first long arms 3001 and connecting to a wheel 314. The ends of the third rotating rod 302 passing through two opposite first long arms 3001 are connected to the wheel 314 via adapter pins. There are five fixing rods 303, which are interlocked on the first long arm 3001 and located between the two third rotating rods 302. The fixing rods 303 are also located at the bottom of the gear box 2. There are six third spur gears 311, which are respectively sleeved on the five fixing rods 303 and the third rotating rods 302 located at the front end. Two adjacent third spur gears 311 mesh, and the third spur gear 311 located at the rear end of the first long arm 3001 meshes with the second spur gear 23.

[0133] Thus, when the motor 26 drives the second spur gear 23 to rotate, the third spur gear 311 can be used to rotate the third rotating rod 302 located at the front end of the first long arm 3001, thereby causing the two wheels 314 located at the front end of the first long arm 3001 to rotate. When the children's vehicle robot 1001 is placed on the ground, the rotation of the two wheels 314 located at the front end of the first long arm 3001 will cause the two wheels 314 located at the rear end of the first long arm 3001 to rotate, thereby enabling the children's vehicle robot 1001 to move forward.

[0134] When the toy robot is assembled into quadruped robot 1002, the required parts and their positional relationships are as follows:

[0135] See attached document Figure 38The gearbox 2 and the head component 1 are each one, with the head component 1 located at the front end of the gearbox 2. Two fixing plates 312 are detachably mounted on the left and right side walls of the gearbox 2 via pins. Two connecting plates 313 are fixed to the front ends of the two fixing plates 312. The fixing plates 312 and the connecting plates 313 are connected via pins. The two fixing plates 312 and their respective connecting plates 313 on the same side form two second long arms 3002. There are two third rotating rods 302 and four first cams 306. The two ends of one third rotating rod 302 pass through the ends of two opposing fixing plates 312 and connect to the center of the first cam 306. The two ends of the other third rotating rod 302 pass through the front ends of two opposing connecting plates 313 and connect to the center of the first cam 306. Three fixing rods 303 are interlocked on the second long arms 3002 and located between the two third rotating rods 302. There are five third spur gears 311, which are respectively sleeved on three fixed rods 303 and two third rotating rods 302 and located at the bottom of gear box 2. Two adjacent third spur gears 311 mesh, and the third spur gear 311 near the front third rotating rod 302 meshes with the second spur gear 23. There are four T-shaped connecting rods 307. Each T-shaped connecting rod 307 is connected to a non-central position of a first cam 306 by a pin at the position between the first sliding hole 3071 and the second sliding hole 3072. The first sliding hole 3071 of each T-shaped connecting rod 307 is sleeved on one end of a fixed rod 303 and located above the second sliding hole 3072.

[0136] Thus, when the motor 26 drives the second spur gear 23 to rotate, the third spur gear 311 can link the two third rotating rods 302 to drive the cam to rotate, thereby enabling the T-shaped connecting rods 307 on both sides to move forward, realizing the action of the quadruped robot 1002 walking forward.

[0137] When the toy robot is assembled into the Turtle Robot 1003, the required parts and their relative positions are as follows:

[0138] See attached document Figure 39There is one gearbox 2 and one head component 1, with the head component 1 located at the front end of the gearbox 2. There are two fixing plates 312, each detachably mounted on the left and right side walls of the gearbox 2 via two pins. There are four connecting plates 313, with one connecting plate 313 connected to each of the front and rear ends of each fixing plate 312. The connection between the fixing plates 312 and the connecting plates 313 is via pins. There are two third rotating rods 302 and four first cams 306. One third rotating rod 302 has its two ends passing through the front ends of two opposing fixing plates 312 and connecting to the first cams 306, while the other third rotating rod 302 has its two ends passing through the rear ends of two opposing fixing plates 312 and connecting to the non-central position of the first cams 306. There are four arc-shaped connecting rods 316 and four T-shaped connecting rods 307. Each T-shaped connecting rod 307 is connected to the off-center position of the first cam 306 via a pin at the position between the first sliding hole 3071 and the second sliding hole 3072. The second sliding hole 3072 is fitted onto the rotating pin connecting the fixed plate 312 and the gear box 2. Every two arc-shaped connecting rods 316 are connected to form a turtle shell 3003. The two turtle shells 3003 are detachably mounted on the left and right side walls of the gear box 2 via fixing pins. One end of each turtle shell 3003 is located above the connecting plate 313 at the front end of the fixed plate 312, and the other end is located behind the connecting plate 313 at the rear end of the fixed plate 312. There are five fixed rods 303, one fixed rod 303 connecting each pair of opposite arc-shaped connecting rods 316. The two ends of one fixed rod 303 are inserted into two opposite fixed plates 312 and located between two third rotating rods 302. The two ends of another fixed rod 303 are respectively inserted into two opposite connecting plates 313 at the front end of the fixed plate 312, and the two ends of yet another fixed rod 303 are respectively inserted into two opposite connecting plates 313 at the rear end of the fixed plate 312. There are three third spur gears 311, respectively disposed on two third rotating rods 302 and on the fixed rod 303 located between the two third rotating rods 302. The third spur gears 311 are located at the bottom of the gearbox 2, with two adjacent third spur gears 311 meshing, and the middle third spur gear 311 meshing with the second spur gear 23.

[0139] In this way, the shape of a turtle is formed. The motor 26 drives the second spur gear 23 to rotate, which in turn drives the two third rotating rods 302 to rotate through the third spur gear 311, thereby driving the first cam 306 to rotate. This causes the bottom of the two front and rear T-shaped connecting rods 307 to move forward, so that the whole turtle robot 1003 moves forward in the shape of a turtle.

[0140] When the toy robot is assembled into the Puppy Robot 1004, the required parts and their relative positions are as follows:

[0141] See attached document Figure 40 and attached Figure 41 There is one gearbox 2 and one head component 1, with the head component 1 positioned on top of the gearbox 2. Two fixing plates 312 are detachably mounted on the left and right side walls of the gearbox 2 via two pins. Two connecting plates 313 are fixed to the rear ends of the two fixing plates 312. The fixing plates 312 and connecting plates 313 are connected via pins. There are two third rotating rods 302 and two symmetrical semicircular parts 308. One third rotating rod 302 has both ends passing through the rear ends of two opposing fixing plates 312 and connecting to a symmetrical semicircular part 308. The other third rotating rod 302 has both ends inserted into the middle of two opposing connecting plates 313. The third rotating rod 302 has both ends passing through the rear ends of two opposing fixing plates 312 and connecting to a symmetrical semicircular part 308 via adapter pins. There are three fixing rods 303, with both ends of one fixing rod 303 inserted into the rear ends of two opposing connecting plates 313. Two fixed rods 303 are located at the front end and middle of two opposing fixed plates 312, respectively, with both ends of each fixed rod 303 inserted into the front end and middle of the two opposing fixed plates 312. The third rotating rod 302 and the fixed rods 303 are both located below the gear box 2. There are at least three third spur gears 311, respectively fitted onto the two third rotating rods 302 and the fixed rod 303 located in the middle of the fixed plates 312. Two adjacent third spur gears 311 mesh, and the third spur gear 311 on the fixed rod 303 meshes with the second spur gear 23. There are two slotted connecting rods 322, which are detachably connected by a pin to form a tail piece 3012, which is fitted onto the fixed rod 303 located at the rear end of the connecting plate 313. There is one wave gear 315, fitted onto the third rotating rod 302 located in the middle of the connecting plate 313. One end of the tail piece 3012 is positioned between two adjacent arc-shaped teeth 3151. There are two T-shaped connecting rods 307, and one end of each rod is respectively fitted onto the pins connecting the left and right side walls of the gear box 2 to the fixing plate 312. The first sliding hole 3071 is limited on the fixing plate 312 by a rotating pin and is located between the two fixing rods 303. The second sliding hole 3072 is arranged in a figure-eight shape with the first sliding hole 3071.

[0142] In this way, the shape of a puppy can be formed. When the second spur gear 23 rotates, it drives the third spur gear 311 to rotate, which in turn causes the third rotating rod 302 to rotate and drives the symmetrical semicircular parts 308 on both sides to rotate, thereby enabling the puppy robot 1004 to move forward. In addition, when the third rotating rod 302 rotates, it drives the wave gear 315 to rotate. During the rotation of the wave gear 315, the arc-shaped teeth 3151 located above the tail part 3012 will cause the tail part 3012 to rotate, causing the tail part 3012 located above the fixed rod 303 to move closer to the gear box 2 and rotate. During this process, the bottom of the tail part 3012 will fall between the next two adjacent arc-shaped teeth 3151. Furthermore, when the bottom of the tail piece 3012 falls between the next two adjacent arc-shaped teeth 3151, under the action of its own weight, the tail piece 3012 located above the fixed rod 303 rotates away from the gear box 2. This back-and-forth motion allows the tail piece 3012 to swing back and forth during the rotation of the wave gear 315, realizing the action of a puppy wagging its tail and improving the simulation of the puppy robot 1004.

[0143] When the assembled robot toy is assembled into Beetle Robot 1005, the required parts and their positional relationships are as follows:

[0144] See attached document Figure 42 There is one gearbox 2 and one head component 1, with the head component 1 located on the front side of the gearbox 2. There are two fixing plates 312, detachably mounted on the left and right side walls of the gearbox 2 via pins. There are four connecting plates 313, detachably mounted on the front and rear ends of the two fixing plates 312 via pins. The fixing plates 312 and connecting plates 313 are connected via pins. There are three third rotating rods 302 and six symmetrical semicircular parts 308. The two ends of one third rotating rod 302 pass through two opposing fixing plates 312 and connect to a symmetrical semicircular part 308. The two ends of another third rotating rod 302 pass through a connecting plate 313 located at the front end of two opposing fixing plates 312 and connect to a symmetrical semicircular part 308. The two ends of yet another third rotating rod 302 pass through a connecting plate 313 located at the rear end of two opposing fixing plates 312 and connect to a symmetrical semicircular part 308. The two ends of the third rotating rod 302 are connected to a symmetrical semi-circular piece 308 via adapter pins after passing through the fixed plate 312 or the connecting plate 313. There are two fixed rods 303, located between two adjacent third rotating rods 302. Both the fixed rods 303 and the third rotating rods 302 are located at the bottom of the gear box 2. There are five third spur gears 311, which are respectively fitted onto the three third rotating rods 302 and the two fixed rods 303. The third spur gear 311 on the middle third rotating rod 302 meshes with the second spur gear 23, and the two adjacent third spur gears 311 mesh with each other.

[0145] In this way, the shape of a beetle can be formed. Among them, the six symmetrical semicircular parts 308 serve as multiple crawling legs of the beetle. When the second spur gear 23 rotates and drives the third spur gear 311 to rotate, the third rotating rod 302 can rotate and drive the symmetrical semicircular parts 308 on both sides to rotate, so that the beetle robot 1005 can move forward.

[0146] When the Walker Robot 1006 model kit is assembled, the required parts and their relative positions are as follows:

[0147] See attached document Figure 43 There is one gear box 2 and one head component 1, with the head component 1 positioned on top of the gear box 2. Two fixing plates 312 are detachably mounted on the left and right side walls of the gear box 2 via pins. Two U-shaped parts 309, lever arm connecting rods 301, T-shaped connecting rods 307, straight connecting rods 322, and one first cam 306 are each present. One third rotating rod 302 is present, with both ends passing through two opposing fixing plates 312 and connecting to the first cam 306. Two fixing rods 303 are located on two opposing fixing plates 312 and on either side of the third rotating rod 302. Each lever arm connecting rod 301 is detachably connected to a non-central position of the first cam 306 via a pin. One end of each lever arm connecting rod 301 is inserted into a U-shaped part 309, and the other end is connected to one end of a T-shaped connecting rod 307 via a pin. Each T-shaped link 307 is detachably mounted on the gear box 2 via a rotating pin on the side connected to the lever arm link 301. The first sliding hole 3071 is located below the second sliding hole 3072 and forms a forward-inclined L-shape with the second sliding hole 3072. One end of each straight link 322 is detachably mounted on the end of the U-shaped member 309 away from the lever arm link 301 via a pin. The two U-shaped members 309 are at least partially opposite each other and are both located below the third rotating rod 302. There is one third spur gear 311, which is sleeved on the third rotating rod 302 and meshes with the second spur gear 23.

[0148] Thus, when the second spur gear 23 rotates and drives the third spur gear 311 to rotate, the third rotating rod 302 can rotate and drive the first cams 306 on both sides to rotate, thereby allowing the U-shaped part 309 to make a forward stepping motion, realizing the movement of the Walker robot 1006.

[0149] When the toy robot is assembled into Crab Robot 1007, the required parts and their positional relationships are as follows:

[0150] See attached document Figure 44 and attached Figure 45There is one gearbox 2 and one head component 1, with the head component 1 located on top of the gearbox 2. There are two fixing plates 312, detachably mounted on the left and right sides of the gearbox 2 via two rotating pins. There are two third rotating rods 302, two straight connecting rods 322, and two U-shaped pieces 309. There are four first cams 306, four T-shaped connecting rods 307, and four symmetrical semicircular pieces 308. The two ends of each third rotating rod 302 pass through two opposing fixing plates 312 and connect to the center of the first cam 306. There is one fixing rod 303, with both ends inserted into two opposing fixing plates 312 and located between the two third rotating rods 302. The third rotating rods 302 and the fixing rods 303 are located below the gearbox 2. There are three third spur gears 311, each sleeved on a fixing rod 303 and one of the two third rotating rods 302. Two adjacent third spur gears 311 mesh, and the third spur gear 311 located on the fixed rod 303 meshes with the second spur gear 23. The T-shaped connecting rod 307 is connected to the off-center position of a first cam 306 via a pin at the position between the first sliding hole 3071 and the second sliding hole 3072. The second sliding hole 3072 is fitted onto the rotating pin connecting the fixed plate 312 and the gear box 2. The center positions of every two symmetrical semicircular parts 308 are connected by a rotating pin to form a crab clip 3004. One end of the crab clip 3004 is fixed to the top of the left side wall of the gear box 2 via a pin. Each of the two ends of the straight connecting rod 322 is connected to one end of the crab clip 3004 by a rotating pin and to the end of the T-shaped connecting rod 307 located above the second sliding hole 3072 by a pin. The first sliding hole 3071 is located below the second sliding hole 3072. The two U-shaped pieces 309 are fixed to the front and rear side walls of the gear box 2 by pins, and the openings of the U-shaped pieces 309 face downwards.

[0151] In this way, a crab shape can be formed. When the side of gear box 2 is the front, when the second spur gear 23 rotates and drives the third spur gear 311 to rotate, the third rotating rod 302 rotates and drives the first cam 306 to rotate. With the help of the T-shaped connecting rod 307, the crab robot 1007 can move laterally. Moreover, when the T-shaped connecting rod 307 moves with the first cam 306, it will pull a symmetrical semi-circular part 308 in the crab claw 3004 back and forth to rotate a certain angle through the straight connecting rod 322, which can realize the opening and closing action of the crab claw 3004, and improve the fun of assembling the robot toy.

[0152] When the model robot toy is assembled into Zombie Robot 1010, the required parts and their positional relationships are as follows:

[0153] See attached document Figure 48There is one gearbox 2 and one head component 1, with the head component 1 positioned on top of the gearbox 2. Two fixing plates 312 are detachably mounted on the left and right side walls of the gearbox 2 via pins. Four connecting plates 313 are detachably mounted vertically at the bottom ends of two fixing plates 312. The fixing plates 312 and connecting plates 313 are connected via pins. Two third rotating rods 302, two first cams 306, two lever arms 301, two T-shaped connecting rods 307, two U-shaped pieces 309, and two second cams 304 are present. One third rotating rod 302 passes through the ends of two opposing fixing plates 312 and the connecting plates 313, connecting to the center of the first cam 306. The other third rotating rod 302 passes through the bottom ends of two opposing connecting plates 313, connecting to the second cam 304. Specifically, the third rotating rod 302 is connected to the first cam 306 via an adapter pin. There are four fixing rods 303. One fixing rod 303 has both ends inserted into two opposing connecting plates 313 located behind the fixing plate 312 and between two third rotating rods 302. Two fixing rods 303 have both ends fixed to two opposing fixing plates 312 and located on one side of a third rotating rod 302. Another fixing rod 303 has both ends fixed to the bottom of two opposing connecting plates 313 located at the front end of the fixing plate 312. There are five third spur gears 311, which are respectively sleeved on two third rotating rods 302, two fixing rods 303 adjacent to the third rotating rods 302, and a fixing rod 303 located at the bottom of the connecting plate 313. The third spur gears 311 on the fixing rods 303 connected to the fixing plate 312 mesh with the second spur gear 23, and two adjacent third spur gears 311 mesh with each other. Each lever arm 301 has its two ends connected to one end of a T-shaped lever 307 and the off-center position of a first cam 306, respectively. A first sliding hole 3071 is located below a second sliding hole 3072. There are six symmetrical semicircular parts 308, with three symmetrical semicircular parts 308 engaging with a pin to form a zombie arm. In each zombie arm 3013, one end of three symmetrical semicircular parts 308 is connected by a pin. The other end of the middle symmetrical semicircular part 308 is placed in the second sliding hole 3072 and connected to a T-shaped lever 307 via a pin. The center positions of the other two symmetrical semicircular parts 308 are connected by pins and located away from the T-shaped lever 307. Both U-shaped parts 309 are fixed to the rear sidewall of the gearbox 2 by pins and are arranged side-by-side, front and rear.

[0154] This creates the shape of a zombie. Two second cams 304, in conjunction with a connecting plate 313, form the zombie's legs. A third spur gear 311 on the front fixed rod 303 balances the zombie robot 1010, allowing it to stand stably. When the second spur gear 23 rotates, it drives the third spur gear 311, causing the third rotating rod 302 to rotate, which in turn drives the first cam 306 and the second cam 304. The rotation of the second cam 304 propels the entire zombie robot 1010 forward. When the first cam 306 rotates, it causes the zombie's arms to rotate up and down by a certain angle via the lever arm connecting rod 301, enabling the arms to swing vertically downwards when the zombie jumps. Furthermore, the first gear 3041 on the outer side of the second cam 304 adds a slight jumping motion to the zombie robot 1010 as it moves forward, making it more lifelike.

[0155] When the assembly robot toy is assembled into the short and stout robot 1008, the required parts and their positional relationships are as follows:

[0156] See attached document Figure 46 and attached Figure 47 There is one gearbox 2 and one head component 1, with the head component 1 positioned on top of the gearbox 2. There are two wheels 314 and two second cams 304, each inserted into one of the two transmission rods 21. Each wheel 314 is coaxially fixed to the center of a second cam 304 via a pin. There are eight arc-shaped connecting rods 316, with four arc-shaped connecting rods 316 connected end-to-end to form an annular wheel 3005. The second cam 304 is located inside the annular wheel 3005, and the first gear tooth 3041 on the second cam 304 meshes with the second gear tooth 3161. The number of T-shaped connecting rods 307, third spur gears 311, and symmetrical semicircular parts 308 are four in total. One end of each of the four symmetrical semicircular parts 308 and one end of each T-shaped connecting rod 307 are fixed to the two top corners of the left and right side walls of the gear box 2 by pins. Each third spur gear 311 is inserted into the center of the symmetrical semicircular part 308 and the second sliding hole 3072 by pins at both ends, thus connecting with the symmetrical semicircular part 308 and the T-shaped connecting rod 307 and being located between the symmetrical semicircular part 308 and the T-shaped connecting rod 307. The third spur gear 311 is located inside the annular wheel 3005, which is located between the symmetrical semicircular part 308 and the T-shaped connecting rod 307.

[0157] Thus, when the transmission rod 21 rotates, it can drive the second cam 304 and the wheel 314 to rotate, thereby causing the ring wheel 3005 to rotate, so that the entire short and stout robot 1008 can move forward.

[0158] When the toy robot is assembled into the crawling robot 1009, the components required for the crawling robot 1009 and their positional relationships are as follows:

[0159] See attached document Figure 49 and attached Figure 50 There is one gearbox 2 and one head component 1, with the head component 1 positioned on top of the gearbox 2. There are two fixing plates 312, detachably mounted on the left and right sides of the gearbox 2 via pins. There are four connecting rods, positioned at the front and rear ends of the two fixing plates 312. The fixing plates 312 are connected to the connecting plates 313 via pins. There are two first cams 306, two lever arms 301, and two third rotating rods 302. There are at least two fixing rods 303, four wheels 314, and eight arc-shaped connecting rods 316. The two ends of the third rotating rod 302 pass through the front ends of the two opposing fixing plates 312 and connect to the center of the first cam 306. Two ends of a fixed rod 303 are respectively connected to the rear ends of two opposing fixed plates 312. One end of every two arc-shaped connecting rods 316 is connected by a rotating pin to form a semi-circular arc connecting rod 317. The three-quarters and one-quarter positions of every two semi-circular arc connecting rods 317 are connected by rotating pins to form a crawling assembly 318. The opening directions of the two semi-circular arc connecting rods 317 in the crawling assembly 318 are opposite. The two ends of each lever arm connecting rod 301 are respectively connected by pins to the non-center position of the first cam 306 and one end of the crawling assembly 318. The two ends of a third rotating rod 302 pass through the other end of the crawling assembly 318 and are connected to wheels 314. The two wheels 314 are respectively connected by pins to the front ends of two opposing connecting plates 313 at the front end of the fixed plate 312. The number of third spur gears 311 is at least two. One third spur gear 311 is sleeved on the third rotating rod 302 with the first cam 306, and the other third spur gear 311 is sleeved on the fixed rod 303 adjacent to the first third spur gear 311 and meshes with the second spur gear 23 and the third spur gear 311 located on the fixed rod 303 respectively.

[0160] Thus, when the second spur gear 23 rotates and drives the third spur gear 311 to rotate, the third rotating rod 302 can rotate and drive the first cam 306 to rotate, thereby pulling the semi-circular connecting rod forward through the lever arm connecting rod 301.

[0161] In one embodiment, reference is made to the appendix. Figure 51Assembly component 3 also includes a hull 323, on which two spaced-apart first lugs 3238 are formed, each with a fourth assembly hole 3237. Two fixing plates 312 are respectively fixed to the front and rear side walls of the gearbox 2. The first lugs 3238 are connected to the fixing plates 312 via pins passing through the fourth assembly holes 3237. Specifically, the first lugs 3238 can be fixed to the gearbox 2 using pins, thus achieving the assembly of the hull 323 and the gearbox 2.

[0162] In the above embodiment, the hull 323 includes a foldable plastic sheet 3230, a first connector 3231, and a cap 3235 with a third connector groove 3236. A first ear seat 3238 is foldably connected to the hull 323.

This allows the sheet-like plastic sheet 3230 to be folded to form a double hull 323, effectively reducing the overall volume of the assembled robot toy in this embodiment and facilitating transportation. Of course, in other embodiments, the hull 323 can also be a single, complete unit, without the need for folding.

[0163] In one embodiment, the assembled robot toy can also be a surfing robot 1011. When the assembled robot toy is assembled into the surfing robot 1011, the components required for the surfing robot 1011 and their positional relationships are as follows:

[0164] See attached document Figure 52 and attached Figure 53There is one gearbox 2 and one head component 1, with the head component 1 mounted on the front side wall of the gearbox 2. There is one hull 323, and the gearbox 2 is fixed to the hull 323. There are two second cams 304, two fixed rods 303, two straight connecting rods 322, and two lever arm connecting rods 301. The two second cams 304 are respectively inserted into the two transmission rods 21, the two fixed rods 303 are respectively inserted into the non-central positions of the two second cams 304, and the two straight connecting rods 322 are respectively sleeved on the two fixed rods 303. There are four arc-shaped connecting rods 316 and four T-shaped connecting rods 307. The two ends of every two arc-shaped connecting rods 316 are connected to form a wave-shaped leg component 3007, and one end of each leg component 3007 is connected to one straight connecting rod 322 via a pin. Two T-shaped links 307 are arranged side-by-side opposite each other via pins to form a foot piece 3006. The first sliding hole 3071 and the second sliding hole 3072 on each T-shaped link are in a V-shape. The two ends of each lever arm link 301 are respectively connected to the other end of the leg piece 3007 and one end of the foot piece 3006 via pins. The middle position of each lever arm link 301 is rotatably connected to the first connector 3231 via a rotating pin. There are six symmetrical semicircular parts 308, and three symmetrical semicircular parts 308 with pins form a paddling arm 3008. In each paddling arm 3008, one end of three symmetrical semicircular parts 308 is connected by pins, the other end of the middle symmetrical semicircular part 308 is placed on a fixed rod 303 via a pin, and the center positions of the other two symmetrical semicircular parts 308 are connected by pins and located away from the fixed plate 312.

[0165] In this way, a surfing shape can be formed. When the surfing robot 1011 is placed on the water surface, when the transmission rod 21 rotates, it can drive the second cam 304 to rotate. Through the fixed rod 303, the straight connecting rod 322, the leg component 3007 and the lever arm connecting rod 301, it drives one end of the foot component 3006 to swing up and down back and forth. And when the fixed rod 303 rotates, it can drive the paddling arm 3008 to rotate to realize the paddling action.

[0166] In one embodiment, the assembled robot toy can also be a rowing robot 1012. When the assembled robot toy is assembled into the rowing robot 1012, the components required for the rowing robot 1012 and their positional relationships are as follows:

[0167] See attached document Figure 54There is one gearbox 2 and one head component 1, with the head component 1 positioned on top of the gearbox 2. There is one hull 323, and the gearbox 2 is fixed to the hull 323. There are two second cams 304, two connecting rods 322, and two lever arm connecting rods 301. The two second cams 304 are respectively fixed to the two transmission rods 21. There are four arc-shaped connecting rods 316, four fixed rods 303, and four T-shaped connecting rods 307. The two fixed rods 303 are respectively inserted into the non-central positions of the two second cams 304. The two connecting rods 322 are respectively sleeved on the two fixed rods 303. The two arc-shaped connecting rods 316 are connected oppositely by pins to form rowing paddles 3009. There are two rowing paddles 3009, each inserted into a fixed rod 303 connected to the first cam 306. Two arc-shaped connecting rods 316 are connected at both ends by two fixing rods 303 to form a life jacket 3011 with a fitting opening 3010. The gear box 2 is placed inside the fitting opening 3010, and the two sides of the life jacket 3011 are fixed to the gear box 2 by pins. One end of two T-shaped connecting rods 307 is connected to the pin connecting the life jacket 3011 and the gear box 2, and the other end is rotatably connected to a straight connecting rod 322 by a pin. The first sliding hole 3071 of the two T-shaped connecting rods 307 is located above the second sliding hole 3072. One end of two lever arm connecting rods 301 is respectively inserted into the two sides of the fixing plate 312. The other two T-shaped connecting rods 307 are respectively connected to a lever arm connecting rod 301 by pins. The first sliding hole 3071 and the second sliding hole 3072 on the two T-shaped connecting rods 307 are in a forward-inclined L-shape and form a human leg 3014 with the two lever arm connecting rods 301.

[0168] Thus, a toy in the shape of a rowing boat is formed. When the transmission rod 21 rotates, it can drive the second cam 304 to rotate, which in turn drives the rowing paddle 3009 to rotate via the fixed rod 303, thereby realizing the rowing action.
