[0070] In some possible implementations, multiple slides 5 are provided on one side of the inner surface of the outer shell 21, and multiple rotating shells 6 are rotatably provided on the truck head main shell 1. Each rotating shell 6 has a cavity and an opening connecting to the cavity. The cavity contains a toy car, and the rotating shell 6 can rotate to the side of the opening to support the slide 5, allowing the toy car to slide out of the opening and onto the slide 5. The rotating shell 6 can hold toy cars, similar to a parking lot. Rotating the rotating shell 6 and connecting to the track creates the effect of the toy car driving out of the parking lot, increasing the toy's fun and interactivity, allowing children to experience more diverse scenarios and operations during play. This design not only meets children's basic needs for toy cars but also stimulates their imagination and creativity through innovative play. Children can simulate real parking and driving scenarios and engage in role-playing games with other children. Furthermore, children can rotate the rotating shell 6 to make the toy car slide out of the opening and along the slide 5, as if participating in a real racing game. Meanwhile, the addition of slide 5 and rotating shell 6 enriches the ways to play with the toy, allowing children to experience more fun and surprises during play.

[0071] In some possible implementations, a maintenance turntable 7 is provided on the inner folding shell 22 for placing the toy car. This design further enhances the interactivity of the toy, allowing children to place the toy car on the maintenance turntable 7 to simulate a real maintenance scenario. By rotating the maintenance turntable 7, they can inspect various parts of the toy car. This simulated maintenance play not only stimulates children's curiosity and desire to explore but also cultivates their hands-on skills and imagination.

[0072] In some possible implementations, the inner folding shell 22 has a circular groove 221 and an arcuate groove 222. The arcuate groove 222 extends along the edge of the circular groove 221 and communicates with the circular groove 221. The maintenance rotating platform 7 has a circular shell 71 and an extension 72 connecting the circular shell 71, with a convex shaft 73 at the end of the extension 72. The circular shell 71 is slidably disposed in the circular groove 221, the extension 72 extends to the arcuate groove 222, and the convex shaft 73 is slidably inserted through the arcuate groove 222. The circular groove 221 positions the maintenance rotating platform 7, and the arcuate groove 222, in cooperation with the convex shaft 73, restricts the rotation angle of the maintenance rotating platform 7, ensuring that the maintenance rotating platform 7 can only rotate within a specific angle range. This guarantees the stability of the maintenance rotating platform 7 during rotation and avoids structural damage or toy car slippage caused by excessive rotation angle. At the same time, this design also increases the toy's operability and fun. Children can observe different angles of the toy car by rotating the maintenance turntable 7, or perform some simple maintenance simulations, thus better experiencing the joy of maintenance work. In addition, the cooperation between the arc groove 222 and the convex shaft 73 makes the rotation of the maintenance turntable 7 smoother, reduces the resistance caused by friction, and improves the toy's service life.

[0073] In some possible implementations, the truck toy includes a folding shell 8 rotatably disposed within the inner folding shell 22. The folding shell 8 can rotate to fit snugly against the inner folding shell 22, or rotate to form an angle with the inner folding shell 22. The folding shell 8 can be a gas station shell or a repair rack shell. This design provides the truck toy with more possibilities for scene simulation. When the folding shell 8 rotates to form an angle with the inner folding shell 22, it can present a three-dimensional shape of a gas station or repair rack, creating a more realistic car service scene for children. Children can park their toy cars next to the gas station shell to simulate refueling; or place toy cars that need repair under the repair rack shell for simple repairs. When these scenes are not needed, the folding shell 8 can rotate to fit snugly against the inner folding shell 22, reducing space occupation and making the toy more compact when stored. This foldable and shape-changing design not only increases the fun and playability of the toy, but also cultivates children's hands-on skills and spatial imagination, allowing them to fully unleash their creativity and imagination to create more interesting ways to play and scenarios.

[0074] In some possible implementations, the inner folding shell 22 has a groove 223 into which the gas station-shaped shell can be rotatably inserted or extended. The groove 223 provides a stable storage location for the gas station-shaped shell. When the gas station scene is not needed, the shell can be easily inserted into the groove 223, fitting snugly against the inner folding shell 22, making the toy's overall appearance neater and preventing damage from shaking during storage or transport. When children want to simulate a gas station scene, they can simply rotate the shell out of the groove 223 to quickly create a realistic gas station environment for their toy cars. This design not only improves the toy's practicality and durability but also enriches its playability and scene simulation functions, allowing children to experience more diverse fun during play.

[0075] In some possible implementations, the truck toy includes a folding robotic arm 9. A ball groove 11 is provided on the main shell 1 of the truck, and a ball head is provided at one end of the folding robotic arm 9, which is movably positioned within the ball groove 11. The folding robotic arm 9 achieves flexible rotation and positioning functions through the cooperation of the ball head and the ball groove 11. This design allows the folding robotic arm 9 to be adjusted at multiple angles according to children's needs, easily handling simulated lifting operations or other interactive activities. The smooth rotation of the ball head within the ball groove 11 not only improves the toy's operability but also increases the fun during play. Children can operate the folding robotic arm 9 to simulate lifting, moving, or placing the toy car in a designated location, experiencing richer gameplay and scene simulations. Simultaneously, this design also trains children's hand-eye coordination and spatial awareness, allowing them to grow and progress continuously during play.

[0076] In some possible implementations, a cavity 12 is provided on the side of the truck cab main shell 1 opposite to the front fender 2. The cavity 12 extends along the height direction of the truck cab main shell 1. The lifting shell 3 is slidably disposed in the cavity 12, and multiple support plates 31 are provided on the lifting shell 3 to support the toy car. The design of the cavity 12 provides a stable sliding space for the lifting shell 3, allowing it to slide smoothly along the height direction of the truck cab main shell 1. The multiple support plates 31 on the lifting shell 3 not only increase the stability of the toy car but also allow multiple toy cars to be placed on the lifting shell 3 simultaneously, further enriching the playability of the toy. Children can place toy cars of different colors and styles on the support plates 31 according to their preferences, simulating a real convoy driving scenario. At the same time, the sliding function of the lifting shell 3 also allows children to adjust the height of the lifting shell 3 to simulate different driving perspectives, increasing the fun and interactivity of the toy.

[0077] In some possible implementations, the folding track 4 includes a first track segment 41, a second track segment 42, and a third track segment 43. The first track segment 41 is fixedly mounted to the lifting shell 3, the second track segment 42 is movably connected to the first track segment 41, and the third track segment 43 is foldably connected to the second track segment 42. A support member 10 is movably mounted on the second track segment 42. In the second deformed state, the support member 10 can rotate and support the truck head main shell 1 to fix the angle of the second track segment 42. This segmented design of the folding track 4 greatly enhances the toy's flexibility and playability. In the first deformed state or folded state, the folding track 4 can be tightly folded for storage, without taking up too much space, making it convenient to carry and store. When entering the second transformation state, as the lifting shell 3 extends, the first track segment 41 moves accordingly. The second track segment 42 unfolds via a movable connection and is rotatably supported by the support member 10 on the truck's main shell 1, ensuring the stability and angle of the track. The third track segment 43 further extends, forming a complete track for the toy car to drive on. This design allows children to freely adjust the shape and length of the track according to their imagination and creativity, simulating various driving routes and scenarios, such as straight tracks, curve challenges, or complex multi-layered tracks. At the same time, the design of the support member 10 also increases the stability of the track, ensuring that the track will not easily shake or collapse even when the toy car is traveling at high speed or performing complex movements, providing children with a safe and stable play environment.

[0078] In some possible implementations, the first track segment 41 includes a track body 411, a swing member 412, and an elastic member. The track body 411 is fixed to the lifting shell 3. The track body 411 has a cavity and multiple openings communicating with the cavity. The swing member 412 is located in the cavity and is rotatably connected to the track body 411. The swing member 412 is provided with a vehicle baffle 414 and a pressing plate 415, which extend out of the corresponding openings. The elastic member is located between the swing member 412 and the track body 411. When an external force is applied to the pressing plate 415, the swing member 412 can rotate, causing each vehicle baffle to retract into the cavity, increasing the deformation of the elastic member. When the external force is removed, the elastic member elastically resets, pushing the swing member 412 back to its original position. The baffle 414 can prevent the car from sliding down the track. Pressing the press plate 415 will cause the baffle 414 to swing downward, releasing the car, which will then slide down the track. This can be used for track racing, further enhancing the playability and fun of the truck head toy.
