[0033] refer to Figures 1 to 5 The present invention discloses a train toy 100, characterized by comprising a train body 1000 and train wheels 1001 rotatably connected to the train body 1000, wherein the wheels of the train wheels 1001 all have a tendency to gradually change along the circumferential direction. The gradual change in the circumferential width of the train wheels 1001 enables the train body 1000 to travel more smoothly, reduces shaking and derailment caused by uneven tracks or ground, and improves the stability and safety of the train toy 100. In addition, the circumferentially varying wheel width creates a dynamic visual effect of the train body 1000 during movement, enhancing the overall visual appeal and increasing the ornamental and entertainment value of the train toy 1000.
[0034] In this embodiment, the train toy 100 also includes a toy car 2000, which is mounted on the train body 1000. The toy car 2000 includes wheels 2001, the width of which gradually changes along the circumference. The gradually changing wheel width increases the contact area between the wheels and the track or the ground, thereby improving grip and ensuring the stability of the toy car 2000 during travel, reducing the risk of overturning.
[0035] In this embodiment, the train wheel 1001 and the trolley wheel 2001 both include an inclined end surface 3000, on which an arc-shaped recessed surface 3001 is provided. The recessed depth of the arc-shaped recessed surface 3001 has a tendency to gradually change along the circumferential direction, so that the train wheel 1001 and the trolley wheel 2001 produce a visual effect of wheel deflection when rotating, thereby increasing the ornamental value and attractiveness of the train toy 100.
[0036] In this embodiment, referring to Figure 3-1 to Figure 3-4 As shown, train wheels 1001 include a first drive wheel 1101 and a second drive wheel 1102. The first drive wheel 1101 includes a front drive wheel 1103 and a rear drive wheel 1104. The front drive wheel 1103, the rear drive wheel 1104, and the second drive wheel 1102 all have a first top end 1105 and a first bottom end 1106 opposite the first top end 1105. The wheel widths of the front drive wheel 1103, the rear drive wheel 1104, and the second drive wheel 1102 all gradually increase from the first top end 1105 to the first bottom end 1106. The change in wheel width can effectively improve the stability of the train during travel and reduce the risk of rollover.
[0037] In this embodiment, a toy vehicle 2000 includes a first toy vehicle 2003 and a second toy vehicle 2004. The vehicle wheels 2001 include a first vehicle wheel 2004 rotatably connected to the first toy vehicle 2003 and a second vehicle wheel 2005 rotatably connected to the second toy vehicle 2004. The second vehicle wheel 2005 has a second top end 2101 and a second bottom end 2102 opposite the second top end. The wheel width of each second vehicle wheel 2005 gradually increases from the second top end 2101 to the second bottom end 2102. This change in wheel width can effectively improve the stability of the train during travel, distribute the pressure on the wheels, reduce wear, extend the service life of the wheels, and reduce the risk of rollover.
[0038] In this embodiment, the first trolley wheel 2004 is transmission-connected to the rear drive wheel 1104 via the main drive wheel 3000. The second trolley wheel 2005 includes a first front wheel 2201 and a first rear wheel 2202. The first front wheel 2201 and the first rear wheel 2202 are transmission-connected to the second drive wheel 1102. The transmission connection between the wheels can improve transmission efficiency, ensure that power can be effectively transmitted to the wheels, and enhance the overall performance of the trolley.
[0039] In this embodiment, the train body 1000 includes a locomotive 1002 and several carriages 1003 detachably connected to the rear of the locomotive 1002. A first hook 1200 is provided at the rear end of the locomotive 1002. The carriages 1003 include at least one first carriage 1201 and at least one second carriage 1202 detachably connected to the first carriage 1201. A first hanging ring 1203 is provided at one end of the first carriage 1201. The first hook 1200 is connected to the first hanging ring 1203, so that the locomotive 1002 is detachably connected to the first carriage 1201. A second hook 1204 is provided at the other end of the first carriage 1201. A second hanging ring 1205 is provided at one end of the second carriage 1202. The second hook 1204 is connected to the second hanging ring 1205. The second hook 1204 is connected to the second hanging ring 1205, so that the first carriage 1201 and the second carriage 1202 are detachably connected. By connecting the hook and the hanging ring, the locomotive and the carriage, and the carriages can be easily disassembled and connected, so that the user can increase or decrease the number of carriages as needed, thereby improving the scalability and adaptability of the train toy 100.
[0040] In this embodiment, the first hook 1200 and the second hook 1204 both include a connecting column 1301 and a spherical snap joint 1302 located at the top of the connecting column 1301. The inner wall surfaces of the first hanging ring 1203 and the second hanging ring 1205 are both provided with an elastic wall 1401. The elastic wall 1401 has an elastic gap 1402, wherein the elastic gap 1402 has a contracted state and an expanded state. When at least part of the spherical snap joint 1302 is clamped on the first hanging ring 1203 or the second hanging ring 1205, the elastic gap 1402 is in an expanded state. When the spherical snap joint 1302 passes through the first hanging ring 1203 or the second hanging ring 1205, the elastic gap 1402 is in a contracted state, so that the first hanging ring 1203 and the second hanging ring 1205 are respectively hung with the first hook 1200 and the second hook 1204. The snap connection between the spherical snap joint 1302 and the elastic wall 1401 in this embodiment provides a firm connection, avoids loosening and falling off of the hanging parts, and enhances the stability of the entire device. Through the contraction and expansion of the elastic gap 1702, the hanging and disassembly operations are simpler and more convenient, and users can easily complete the connection and separation of the device.
[0041] In this embodiment, a retaining groove 1303 is provided between the connecting post 1301 and the spherical snap joint 1302. A retaining ridge 1403 is also provided on the elastic wall 1401. When the spherical snap joint 1302 passes through the first or second hanging ring 1203, the retaining ridge 1403 engages with the retaining groove 1303, allowing the first and second hanging rings 1203, 1205 to be respectively attached to the first and second hooks 1200, 1204. The design of the retaining groove 1303 and retaining ridge 1403 ensures a more secure connection between the hanging ring 1005 and the hook 1004. The retaining ridge 1403 engages with the retaining groove 1303, preventing the hanging ring 1005 from slipping or detaching, significantly improving the stability and security of the connection.
