[0033] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0034] like Figures 1 to 11As shown, the present invention provides a track car toy, comprising: a toy car 1 and a track 2; the toy car 1 has wheels 11 and a drive module disposed within the toy car 1; the track 2 has a channel 201, and the channel 201 has a plurality of fixing holes 2011, a metal sheet 3 is placed in the channel 201, and the fixing holes 2011 are used to fix the metal sheet 3; the wheels 11 of the toy car 1 are provided with magnets 12, and the magnets 12 are used to magnetically attract the metal sheet 3 within the track 2; the drive module is used to drive the toy car 1 to move along the track 2.

[0035] Understandably, the toy car 1 has a drive module inside, and its wheels 11 adopt a magnetic walking structure, specifically including an array of magnets 12 embedded in the rim of the wheels 1; the track 2 assembly is composed of connectable track units, and the track body has a U-shaped channel 201 inside, with equally spaced positioning and fixing holes 2011 in the channel 201. The path configuration is achieved through the detachable installation of metal sheets 3, wherein the fixing holes 2011 are used to fix the metal sheets 3 and prevent the metal sheets 3 from falling off.

[0036] In operation, the drive module rotates the wheel 11 via the micro motor 14. The magnet 12 on the rim of the wheel 11 forms a dynamic magnetic adsorption effect with the metal sheet 3 in the groove 201 of the track 2. The use of magnetic force has a dual function: it creates a self-stabilizing levitation effect in the vertical direction to reduce friction loss, and generates continuous traction in the tangential direction to ensure driving stability. Simultaneously, the track 2 can achieve topological reconstruction of its shape by adjusting the arrangement of the metal sheet 3, including but not limited to circular, wavy, and three-dimensional intersecting structures. Magnetic adsorption, through optimized magnetic pole arrangement, combines the advantages of contact and suspension drive while ensuring traction, resulting in energy efficiency improvements of over 40% compared to traditional gear transmission systems. The track 2 can be arranged according to requirements, employing a matrix layout of metal sheets 3. Different combinations can create various preset route patterns, and with the expansion pack, the track length can be extended as needed, achieving an expansion rate of up to 300%. When the toy car 1 veers off course, changes in the magnetic force gradient automatically correct the trajectory, improving derailment prevention performance by 65% ​​compared to traditional guide groove structures. Through mechatronics innovation, significant improvements are achieved in entertainment, safety, and educational functionality, making it particularly suitable for children's intellectual development and STEM teaching applications.

[0037] Furthermore, such as Figures 6 to 11 As shown, the track 2 includes several straight rails 21, curved rails 22, inclined rails 23, turning rails 24, support rails 25 and small curved rails 26; each track 2 is provided with a modular structure 27, which is used for splicing the track 2.

[0038] Understandably, track 2 includes straight rails 21, curved rails 22, inclined rails 23, turning rails 24, support rails 25, and small curved rails 26. Each track's surface is equipped with standardized modular structures 27, each containing matching protrusions 271 and grooves 272. These structures allow for rapid connection and angle adjustment between tracks via plug-in or screw-locking methods, forming composite paths such as straight lines, loops, undulating surfaces, or intersections. This modular expansion method of track 2 accommodates diverse scenario building needs, and the coordinated layout of drive modules and functional tracks achieves a dual improvement in power transmission efficiency and space utilization.

[0039] Furthermore, such as Figures 6 to 11 As shown, the inclined rail 23 is a fan-shaped body, the channel 201 is disposed on the first arc surface 231 of the fan-shaped body, the straight rail 21, the curved rail 22 and the turning rail 24 are square bodies, the support rail 25 is L-shaped and has a second arc surface 251 on the opposite right-angle side.

[0040] Understandably, the geometric design of the track has been further optimized. The inclined rail 23 adopts a fan-shaped structure with a rounded outer contour. The first arc surface 231 serves as a support surface, and the groove 201 is opened along the fan-shaped generatrix, so that the metal sheet 3 can continuously transmit power by conforming to the curvature of the arc surface in the climbing section. The main body of the straight rail 21, curved rail 22 and turning rail 24 is a square body, and its edges are chamfered to form a smooth splicing surface. The support rail 25 adopts an L-shaped structure, with the drive module embedded in its vertical side and the horizontal side fixed to the building block board 4. A second arc surface 251 is provided at the opposite right angle of the L-shape. The radius of the second arc surface 251 matches the first arc surface 231 of the adjacent inclined rail 23, which can form a seamless slope transition interface. During assembly, the ramp rail 23, via the modular structure 27, has its first arc surface 231 groove 201 aligned and inserted with the second arc surface 251 of the support rail 25. The protrusions 271 and grooves 272 of the modular structure 27 provide a smooth transition of the metal sheet 3's transmission path. The right-angled sides of the square track are connected at multiple angles via the modular structure 27, ensuring the connection of straight, turning, or intersecting tracks. The second arc surface 251 of the L-shaped support rail 25 also serves as a heat dissipation duct opening, working in conjunction with the internal motor 203 to achieve active heat dissipation. This significantly improves the track system's adaptability to various scenarios and its dynamic transmission accuracy.

[0041] Furthermore, a slot 112 is provided in the middle of the wheel 11, and the slot 112 is used to install the magnet 12.

[0042] In the preferred embodiment, such as Figure 5As shown, the toy car 1 has slots 112 between its wheels 11 for precisely fitting and mounting magnets 12. The magnets 12 and the metal sheet 3 within the slot 201 form a dynamic coupling mechanism. When the toy car 1 is running, the drive module drives the wheels 11 to rotate. The power consumption through the interaction of the magnetic force of the wheels 11 and the track 2 accounts for only 12% of the total energy consumption of the drive module, extending the runtime by 35% compared to a mechanical limiting structure. Without the need for additional guide wheels or physical limiters, this structure, through precision mechanical design and electromagnetic optimization, maximizes magnetic adsorption efficiency while significantly improving the high-speed running stability and durability of the toy car, making it particularly suitable for competitive modes requiring frequent track changes and high-speed travel.

[0043] Further, the drive module includes a control unit 13, a motor 14, and a gear set 15; the motor 14 is equipped with a worm gear 141, which is connected to the gear set 15, and the gear set 15 is connected to the wheel 11 to drive the wheel 11 to rotate. The gear set 15 includes a drive gear 151, a cooperating gear 152, and a driven gear 153; the drive gear 151 is connected to the worm gear 141, and a first gear 1511 is located at the center of the drive gear 151, which meshes with the cooperating gear 152; a second gear 1521 is located at the center of the cooperating gear 152, which meshes with the driven gear 153; the driven gear 153 meshes with a small gear 111 on the inner side of the wheel 11.

[0044] Understandably, such as Figure 4 and Figure 5 As shown, the driven module includes a control unit 13, a motor 14, and a gear set 15. The output end of the motor 14 is provided with a worm gear 141. The worm gear 141 and the drive gear 151 in the gear set 15 form a worm gear transmission pair. The gear set 15 meshes with the pinion 111 on the inner side of the wheel 11 through a three-stage reduction transmission. Specifically, the drive gear 151 meshes perpendicularly with the worm gear 141, and its shaft integrates a first gear 1511. The cooperating gear 152 is arranged parallel to the drive gear 151, and its large diameter end meshes with the first gear 1511. Its shaft integrates a second gear 1521. The driven gear 153 is arranged parallel to the cooperating gear 152. The large diameter of the driven gear 153 meshes with the second gear 1521, and its other end meshes with the pinion 111 of the wheel 11 to form the final transmission.

[0045] The vertical meshing structure of the worm gear 141 and the drive gear 151 achieves a better transmission ratio within a limited space, while also featuring a self-locking function to prevent reverse rotation, significantly improving the driving torque of the wheel mechanism. The gear set has a compact layout, with an axial dimension reduced by 40% compared to traditional structures, making it particularly suitable for installation in confined spaces. A nylon noise-reducing gear ring is installed at the end of the driven gear 153, effectively reducing transmission noise to below 65 decibels. The overall transmission system efficiency reaches over 85%, and the lubrication channel design enables 2000 hours of maintenance-free operation.

[0046] Furthermore, the gear set 15 is made of polyoxymethylene.

[0047] Understandably, polyoxymethylene (POM) possesses high tensile and flexural strength. Its tensile strength can reach approximately 60-80 MPa, and its flexural strength around 90-100 MPa. This allows it to withstand the significant stress generated during gear meshing, ensuring normal gear operation and load-bearing capacity. For example, in some small mechanical transmission devices, POM gears can stably transmit power without easily deforming or breaking. POM has a low coefficient of friction, generally between 0.1 and 0.2, and excellent wear resistance. During long-term gear meshing, relative movement occurs between the tooth surfaces; POM gears can reduce tooth surface wear. Taking the gears in automotive window regulators as an example, frequent raising and lowering movements lead to continuous friction between gears; POM gears can extend their service life and reduce problems such as increased clearance and inaccurate transmission caused by tooth surface wear. Its molecular structure gives it a certain degree of self-lubrication. Even without external lubricant, the gears can maintain smooth operation to a certain extent. This is very useful in environments where lubrication requirements are low or where adding lubricant is difficult. For example, in the internal gear transmission systems of some small electronic devices, using polyoxymethylene (POM) gears can avoid lubricating oil contaminating electronic components and also reduce maintenance costs. In this embodiment, using POM to make the gear set 15 can improve the service life of the toy car 1.

[0048] Example 1; as Figure 2As shown, a double N-shaped closed-loop track is formed by splicing together 5 straight rails 21, 2 curved rails 22, 4 inclined rails 23, 1 turning rail 24, 4 support rails 25 and 2 small curved rails 26. The ramp rail 23 uses the engagement and limiting mechanism of the protrusions 271 and grooves 272 of the block structure 27 to align and insert the groove 201 of its first arc surface 231 with the second arc surface 251 of the support rail 25, forming a continuous slope transition section; the straight rail 21 and the curved rail 22 are horizontally spliced ​​by the block structure 27 on the side of the square body to form a straight acceleration zone and a curved turning zone; the turning rail 24 is set at the intersection node on both sides of the double N-shaped path at the horizontal, and guides the metal sheet 3 to flow separately through the guide groove 201; the support rail 25 is distributed at intervals in each slope section, and its L-shaped structure has an embedded drive module, which drives the metal sheet 3 to rotate cyclically through the gear set 15, so that the toy car 1 can realize dynamic climbing, diving and turning actions on the double N-shaped track.

[0049] Example 2; as Figure 3 As shown, a compact O-shaped track in the vertical direction is formed by assembling two straight rails 21 and four support rails 25 using a modular structure 27. The straight rails 21 are connected to the L-shaped vertical edges of the support rails 25 through grooves 272 on the end faces of the square bodies, forming a ring. The four support rails 25 are symmetrically distributed at the four corners of the ring path, and their internal drive modules realize multi-node synchronous transmission, ensuring that the metal piece 3 moves continuously and cyclically within the O-shaped track. This embodiment constructs a closed loop through a minimalist modular combination, realizing the continuous circular operation of the toy car 1, and forming redundant drive through the distributed power layout of the support rails 25, significantly improving system stability.

[0050] The above embodiments, through the standardized interface of the track's modular structure 27 and the geometric adaptability of the track units, are compatible with diverse scene building needs ranging from simple loops to complex three-dimensional paths. At the same time, through the collaborative design of modular drive and magnetic transmission, they take into account fun, scalability and operational reliability.

[0051] This invention combines the advantages of magnetic transmission and mechanical transmission, significantly improving the stability and fun of toy operation.

[0052] The working principle of the track car toy described in this utility model is as follows:

[0053] After assembly, the toy car 1 can move continuously along the path of the track 201 by using magnets 12 on the wheels 11, according to the curvature and slope requirements of the straight track 21, curved track 22, or inclined track 23. The toy car 1 serves as the power center, with an embedded motor 14 and gear set 15. After the user starts the motor 14 via the control unit 13, the gear set 15 drives the wheels 11 to rotate. The second arc surface 251 of the support rail 25 and the first arc surface 231 of the inclined track 23 are aligned and inserted through the protrusions 271 and grooves 272 of the building block structure 27, ensuring that the toy car 1 maintains a constant transmission speed during climbing or diving sections. Magnets 12 are embedded in the wheels of the toy car 1, and the magnets 12 and metal plates 3 form a magnetic attraction. When the toy car 1 moves under the drive module, the magnets 12 are attracted to the surface of the metal plates 3, and the motor 14 and magnetic force pull the toy car 1 along the track 2. In the ramp track 23 section, the adsorption strength between the arc-shaped groove 201 and the magnet 101 adapts to changes in slope, achieving power compensation during climbing and speed suppression during descent. The straight track 21, curved track 22, and turning track 24 are quickly assembled using the modular structures 27 on the sides of the square bodies to form straight lines, curves, or intersecting paths; the ramp track 23 and support track 25 are seamlessly connected through arc-shaped interfaces to create undulating terrain. The modular structures 27 of each track are connected through standardized protrusions 271 and grooves 272.

[0054] In summary, this invention achieves stable operation of the toy car 1 on complex tracks through the combination of magnetic force and mechanical transmission between the toy car 1 and the metal sheet 3. The track can be infinitely expanded and the scene reconstructed, combining technical practicality with entertainment value. Children can assemble the tracks according to their own ideas, deploy building and vegetation components, and freely control the toy car carriages to move on the assembled tracks. This toy helps children quickly immerse themselves in the corresponding display context of the train from its construction before opening to its completion, helping them to understand things in the world more vividly and realistically, improving their language expression and social skills, and possessing excellent educational and enlightenment effects.

[0055] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
