[0028] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments thereof. Please refer to... Figures 1 to 2 One embodiment of the present invention provides a toy car, including: a body 10 and a walking assembly 20 disposed on the body 10;

[0029] The walking assembly 20 includes multiple wheels 21, magnetic components 211, a transmission mechanism 22, and a power module 23. The wheels 21 are rotatably mounted on the bottom of the vehicle body 10. The magnetic components 211 are used to magnetically engage with the magnetic track and can move on the magnetic track. The power module 23 is driven by the wheels 21 through the transmission mechanism 22.

[0030] The shape of the vehicle body 10 can be designed according to actual needs. For example, the vehicle body 10 can be designed into various shapes such as a futuristic train or a beetle.

[0031] The toy car can use a lithium-ion rechargeable battery 11 as a power source, and the lithium-ion rechargeable battery 11 is electrically connected to the power module 23.

[0032] The toy car of this invention is adapted to travel on a magnetic track. The magnetic track has a running rail, and iron bars are installed inside the running rail. The working principle of the toy car according to one embodiment of this invention is explained below:

[0033] The wheels 21 of the walking component 20 are magnetically attracted to the iron bars of the walking track, so that the wheels 21 are stably engaged with the magnetic track, preventing the toy car from coming off the magnetic track. The power module 23 drives the wheels 21 to rotate through the transmission mechanism 22, thereby making the wheels 21 move along the magnetic track, improving the stability of the toy car's movement. The energy loss required for movement is low, and due to the magnetic force, the toy car can be well adapted to the three-dimensional magnetic track. The toy car can move uphill, downhill, turn, and upside down on the three-dimensional magnetic track.

[0034] Please see Figures 3 to 5 The specific structure of the wheel 21 can be designed according to actual needs. For example, in some optional embodiments, the wheel 21 includes two wheel bodies 212 and a rotating shaft 213. Both wheel bodies 212 are mounted on the rotating shaft 213, which rotates in conjunction with the vehicle body 10. The walking assembly 20 includes multiple magnetic elements 211, which are correspondingly disposed between the two wheel bodies 212. The two wheel bodies 212 and the magnetic elements 211 can jointly support the entire toy car. The magnetic elements 211 and the two wheel bodies 212 can all contact the iron bar, so there are three support points in the axial direction of the rotating shaft 213, which effectively improves the support stability.

[0035] Please see Figure 6 Of course, in another alternative embodiment, the magnetic component 211 can be a flat neodymium magnet disposed at the bottom of the vehicle body 10, with multiple wheels arranged on both sides of the flat neodymium magnet. Rubber O-rings are embedded in the wheels 21 so that the wheels 21 are not easy to slip when the flat neodymium magnet is attracted to the magnetic track.

[0036] However, compared to flat neodymium magnets, placing magnetic components on wheels provides higher magnetic adhesion stability, less energy loss, and is more suitable for three-dimensional travel tracks.

[0037] In some alternative embodiments, a friction layer is provided on the outer side of the wheel 212. The friction layer helps to prevent the wheel 21 from slipping when it is moving and stabilizes the magnetic attraction force of the magnetic component 211.

[0038] The specific structure of the friction layer can be designed according to actual needs. For example, in order to facilitate the formation of the friction layer, in some optional embodiments, the wheel body 212 is fitted with a rubber ring 214, and the friction layer is formed on the rubber ring 214.

[0039] The specific structure of the wheel body 212 can be designed according to actual needs. For example, in some optional embodiments, the wheel body 212 includes a support sleeve 215 and a wheel plate 216. The wheel plate 216 is disposed on the side of the support sleeve 215 away from the magnetic component 211. A groove 217 is formed between the wheel plate 216 and the support sleeve 215. A rubber ring 214 is sleeved on the outside of the support sleeve 215 and located in the groove 217. The position of the rubber ring 214 is restricted by the wheel plate 216, so that the two rubber rings 214 and the magnetic component 211 are restricted between the wheel plates 216 of the two wheel bodies 212, making the wheel 21 structure stable.

[0040] In some alternative embodiments, the wheel 21 further includes two washers 218, which are correspondingly disposed between the support sleeve 215 and the magnetic element 211, and abut against the rubber ring 214. The washers 218 improve the fit stability between the rubber ring 214 and the magnetic element 211, preventing loosening between the structures. In this embodiment, a groove 217 is formed between the washer 218, the wheel plate 216, and the support sleeve 215.

[0041] Please see Figure 7 and Figure 8 The specific structure of the power module 23 can be designed according to actual needs. For example, in some optional embodiments, the power module 23 includes a drive motor 231 and a worm gear 232. The transmission mechanism 22 includes a reduction gear set 221. The output shaft of the drive motor 231 is connected to the worm gear 232, and the worm gear 232 meshes with the reduction gear set 221. A driven gear 219 is provided on the wheel 21, and the driven gear 219 meshes with the reduction gear set 221. The output shaft of the drive motor 231 rotates to drive the worm gear 232 to rotate. The rotation of the worm gear 232 drives the driven gear 219 to rotate through the reduction gear set 221, thereby driving the wheel 21 to rotate.

[0042] In this embodiment, the driven gear 219 is mounted on one of the wheel bodies 212, so that the driven gear 219 and the wheel body 212 form a gear wheel. The wheel 21 clamps the magnetic element 211 by two washers 218. The magnetic element 211 is a disc-shaped neodymium magnet. The gear wheel and the other wheel body 212 clamp the washer 218 and then press it into the rotating shaft 213. Finally, the rubber ring 214 is embedded into the groove 217, thereby forming the wheel 21.

[0043] The specific structure of the reduction gear set 221 can be designed according to actual needs. For example, in some optional embodiments, the reduction gear set 221 includes multiple reduction gears 222 and multiple spur gears 223. The reduction gears 222 and spur gears 223 are rotatably mounted on the vehicle body 10. The multiple reduction gears 222 mesh sequentially. The worm gear 232 is driven by the reduction gear 222 located at the head end. The reduction gear 222 located at the tail end meshes with multiple spur gears 223 respectively. The spur gears 223 mesh with the driven gear 219. The worm gear 232 drives the multiple reduction gears 222 to rotate, and the reduction gears 222 located at the tail end drive the multiple spur gears 223 to rotate. Each spur gear 223 drives the corresponding driven gear 219 to rotate. In this embodiment, two wheels 21 are provided. The power of the two spur gears 223 is transmitted to the corresponding wheels 21 through gear wheels, so that the two wheels 21 maintain the same rotational speed.

[0044] In some optional embodiments, the transmission mechanism 22 further includes a gear clutch 224. The reduction gear 222 at the tail end is connected to multiple spur gears 223 via the gear clutch 224. The reduction gear 222 at the tail end drives the multiple spur gears 223 to rotate via the gear clutch 224. The principle and structure of the gear clutch 224 are well known to those skilled in the art and will not be described in detail here. In this embodiment, the gear clutch 224 is a two-stage gear with clutch function.

[0045] In some alternative embodiments, the reduction gear 222 is a two-stage gear, with the number of teeth in the first-stage gear portion of the reduction gear 222 being greater than the number of teeth in the second-stage gear portion. The first-stage gear portion of the reduction gear 222 located at the head end meshes with the worm 232, and the first-stage gear portion of the reduction gear 222 meshes with the second-stage gear portion of the adjacent reduction gear 222. The second-stage gear portion of the reduction gear 222 located at the tail end meshes with the gear clutch 224.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
