[0035] Reference Figure 1 In the preferred embodiment, the track 10 includes a plurality of splicing pieces 2, and adjacent splicing pieces 2 are detachably fixedly connected. Specifically, the track 10 is composed of a plurality of detachable splicing pieces 2.

[0036] In the preferred embodiment, the splicing piece 2 includes a straight rail piece 23, a planar turning piece 24 (bend), a vertical turning piece 25 (for forming a ramp or an arch bridge), and a cross track piece 26 (crossing). These components can be combined through the connecting mechanisms at their ends or sides, allowing users to build various complex track 10 layouts such as straight lines, loops, and three-dimensional intersections. The splicing pieces 2 of the track 10 adopt a unified interface standard, ensuring that different types of splicing pieces 2 can be compatibly spliced with each other. For example, the straight rail piece 23 can be directly connected with the planar turning piece 24 or the cross track piece 26, and the vertical turning piece 25 can also be smoothly connected with various track 10 pieces.

[0037] Reference Figure 1 And Figure 2In the preferred embodiment, the splicing piece 2 is provided with a fixing groove 21 and a fixing block 22, and the fixing block 22 is detachably fixed in the fixing groove 21 of the splicing piece 2 adjacent thereto. In order to achieve quick and stable connection, the fixing block 22 and the fixing groove 21 are respectively arranged on the adjacent splicing pieces 2. The fixing block 22 can be accurately inserted into the fixing groove 21 of the adjacent splicing piece 2. In one embodiment, the fixing block 22 is clamped with the adjacent fixing groove 21; the connection mode can be a simple clamping (buckling type), which relies on the elastic deformation of the plastic part itself to realize locking and unlocking. For example, the fixing block 22 can be designed as a structure with barbs, and the fixing groove 21 is provided with a corresponding socket. When inserted, the barbs are elastically deformed, and after being in place, they are snapped back. This way of connection is firm and easy to operate.

[0038] Reference Figure 1 and Figure 3 In a further preferred embodiment, the upper surface of the cross rail piece 26 is provided with a cross rail 4 and a clamping groove 12, and the four side surfaces of the cross rail piece are also respectively provided with a fixing groove 21 and a fixing block 22. Specifically, the cross rail piece 26 is a key component for realizing a complex road network. The upper surface thereof is provided with two cross-shaped strip grooves 261. Each strip groove 261 is fixedly installed with a rail 4. The rail 4 is preferably integrally formed, wherein the middle part is processed to form a continuous rack 11, and the two sides of the rack 11 are raised to form a convex edge 41. When the rail 4 is fixed in the strip groove 261, the convex edges 41 on both sides of the rail 4 and the side walls of the strip groove 261 form two continuous clamping grooves 12. The tooth shape of the rack 11 can be involute tooth shape, circular arc tooth shape or other suitable tooth shape that is suitable for transmission and easy to process.

[0039] In a further preferred embodiment, a square-shaped conversion piece 5 is arranged at the intersection center of the two bar grooves 261. The conversion piece 5 is a core component to ensure the smooth passing of the trolley through the intersection. Its four sides are respectively directed towards the four directional track bars 4, and each side is spaced apart from the corresponding directional track bar 4 by a small preset distance, which ensures that the gear 61 can smoothly pass through, and cannot be too large to avoid jamming, usually the distance is between 0.5-2mm, the specific value can be adjusted according to the gear 61 module and machining accuracy. The width of the four tooth-like side walls 52 of the conversion piece 5 is the same as the width of the rack 11, to ensure the continuity of the guide. The four corners of the conversion piece 5 (i.e. the position of the intersection of the four tooth-like side walls 52) are provided with double-sided protrusions 53 protruding towards the adjacent track bar 4. The outer edges of these double-sided protrusions 53 must be precisely aligned with the inner edges of the protrusions 41 on the track bar 4, thereby forming a complete, closed card slot 12 channel, ensuring that the trolley's clamping buckle 62 can smoothly transition and will not come off at this point.

[0040] Most importantly, a plurality of tooth-like protrusions 51 are arranged in the four tooth-like side walls 52 of the conversion piece 5. The side shape (tooth shape) of these tooth-like protrusions 51 matches the side shape of the teeth of the rack 11, and the spacing between adjacent tooth-like protrusions 51 is also exactly the same as the spacing between adjacent two teeth on the rack 11. The purpose of this design is that when the trolley's gear 61 rolls over the conversion piece 5, these tooth-like protrusions 51 can temporarily "act as" teeth, continue to mesh with the gear 61, and provide continuous driving force and guidance for the trolley, effectively avoiding the phenomenon of power interruption, slipping or jamming caused by the gear 61 hanging in the air at the intersection center. The tooth-like protrusions 51 can be integrally injection molded with the conversion piece 5, or they can be installed as separate parts.

[0041] Reference Figure 2 In a preferred embodiment, the upper surface and the lower surface of the planar turning piece 24 (bend) are provided with racks 11 and card slots 12. This means that the track 10 can be used in reverse, one side can be used after the other side is worn out, prolonging the service life, and the turning piece can also be turned in two different directions, increasing its use frequency; more importantly, it can realize the construction of double-layer track 10 or circular track 10, such as creating a "overpass" effect, greatly improving the interest and creativity of the toy. The racks 11 and card slots 12 extend along the circular arc trajectory, and the pitch must be uniform during processing to ensure smooth operation of the gear 61 on the bend.

[0042] Reference Figure 4In the preferred embodiment, the car body 60 is the moving part of the system. Inside the car body 60, there is a power supply (such as a battery compartment, which can be installed with a 5 or 7 battery, or a built-in rechargeable lithium battery) and a control unit (such as a simple switch, or a more complex wireless receiving module for remote control). Inside the car body 60, there is a micro motor fixedly installed. The output shaft of the motor extends downward and directly or through a reduction gear set drives a gear to rotate. The gear 61 is rotatably connected to the lower part of the car body 60, and its position and size are designed to be able to perfectly mesh with the rack 11 on the track 10. The motor drives the gear 61 to rotate, and the gear 61 meshes with the fixed rack 11 to generate a reaction force to push the car body 60 forward or backward along the track 10.

[0043] On both sides of the drive gear 61, a pair of clamping buckles 62 are symmetrically installed. This pair of clamping buckles 62 can be coaxial with the gear 61 but independently installed parts, or can be part of the chassis of the car body 60. Its function is to be clamped into the clamping groove 12 on both sides of the track bar 4 when the gear 61 meshes with the rack 11 to drive. More preferably, an inner protrusion 621 is provided on the inner side of the clamping buckle 62 (i.e. the side facing the gear 61). When the clamping buckle 62 is clamped into the clamping groove 12, this inner protrusion 621 will abut the side or lower surface of the protrusion 41 on the track bar 4. This design greatly increases the contact area between the car body 60 and the track 10, and can more effectively limit the displacement of the car body 60 in the horizontal and vertical directions, preventing it from jumping, tilting or even derailing when running at high speed, turning or passing through the intersection, greatly improving the stability and reliability of the operation. The clamping buckle 62 can be made of a material with a certain elasticity, such as POM or nylon, to facilitate clamping into the clamping groove 12 and providing appropriate clamping force.

[0044] When the car body 60 is running, place the trolley on the assembled track 10, ensure that the gear 61 at the bottom of the car body 60 meshes with the rack 11 of the track 10, and the clamping buckles 62 on both sides are embedded in the corresponding clamping grooves 12. Start the switch, the motor drives the gear 61 to rotate. The gear 61 obtains the driving force by meshing with the rack 11, thereby driving the car body 60 to move forward. Throughout the running process, the clamping buckle 62 is always limited to move within the clamping groove 12, playing a strict guiding and anti-derailing role. Even through the conversion piece 5 of the intersection track piece 26, the gear 61 can obtain power through continuous meshing with the similar tooth protrusion 51, and the clamping buckle 62 can smoothly pass through the smooth channel formed by the protrusion 41 of the track bar 4 and the protrusion 53 on both sides of the conversion piece 5, realizing seamless and stable turning or straight running.

[0045] The technical features of the above embodiments can be combined in any way. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present disclosure.
