Description

Technical Field

[0001] This utility model relates to the technical field of toy vehicles, specifically a push-pull device for toy vehicles. Background Technology

[0002] Toy trains are mainly powered by batteries to drive motors that make the wheels turn and move. They serve as a medium for children and teenagers to learn about science and trains, and are also a type of electric toy.

[0003] For example, a toy car push-pull device with authorization announcement number "CN209752183U" solves the problem that the front of the toy car is easily damaged when the toy car is in use. The above-mentioned device works by the anti-collision block being the first to be hit when the toy car is in motion. The anti-collision block is compressed by the impact, and the spring reduces the impact force through its own elasticity. However, considering that the existing toy car push-pull device only realizes the basic function of "forward / backward", it lacks interaction with other mechanical structures and is difficult to meet children's needs for immersive scene experience. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing toy car push-pull devices, and to propose a toy car push-pull device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a toy car push-pull device, comprising a car bottom and a car body, wherein the car seat is threadedly connected to the car body by bolts, the inner wall of the car bottom is fixedly connected to a support block, the inner wall of the support block is rotatably connected to a connecting rod, the end of the connecting rod is fixedly connected to a wheel, and a push-pull mechanism is connected to the outer wall of the connecting rod.

[0006] This design features a transparent plastic base, allowing children to more intuitively observe the internal transmission mechanism while playing, thus enhancing their understanding of mechanical transmission. The connecting rod rotates inside the support block, providing stable support for both the connecting rod and the wheels.

[0007] Preferably, the push-pull mechanism includes a first gear, the inner wall of the first gear is fixedly connected to a connecting rod, the outer wall of the first gear meshes with a second gear, the inner wall of the second gear is rotatably connected to a push rod, the inner wall of the push rod is engaged with a locking block, and the outer wall of the locking block is fixedly connected to a fixing block.

[0008] When this feature is activated, the second gear meshes with the first gear, thereby driving the connecting rod and the wheel to rotate.

[0009] Preferably, the lower end of the fixing block is fixedly connected to the bottom of the vehicle, and the outer wall of the vehicle body is connected to an anti-collision mechanism.

[0010] This setting provides a support position for the card block, making the card block installation position more stable.

[0011] Preferably, the anti-collision mechanism includes a first magnetic block, the outer wall of the first magnetic block is fixedly connected to the vehicle body, the outer wall of the first magnetic block is attracted to a second magnetic block, the outer wall of the magnetic block is fixedly connected to a rubber block, and the outer wall of the rubber block is fixedly connected to the anti-collision block.

[0012] This feature uses a magnetic design, combined with a rubber buffer layer, to effectively reduce the impact of collisions on the vehicle body.

[0013] Preferably, the surface of the vehicle bottom is fixedly connected to the connecting block, the outer wall of the connecting block is fixedly connected to the spring, and the end of the spring abuts against the push rod.

[0014] This push-pull mechanism achieves smooth power transmission through a gear transmission system. When the push rod is subjected to force, the second gear drives the first gear to rotate, which in turn drives the connecting rod and the wheel to rotate.

[0015] Preferably, the surface of the vehicle bottom is threadedly connected to the mounting frame by bolts, the inner wall of the mounting frame is fixedly connected to the servo motor, the output end of the servo motor is fixedly connected to the round rod, and the outer wall of the round rod is rotatably connected to the mounting frame.

[0016] This feature, which links the servo motor and gear set, provides additional power reserves for the toy car, enhancing the fun of playing with it.

[0017] Preferably, one end of the mounting frame is fixedly connected to the third gear, and the end of the third gear meshes with the second gear.

[0018] This setting allows the mounting frame to enclose the servo motor, thus protecting it.

[0019] The toy car push-pull device proposed in this utility model has the following advantages: through the transparent material of the car bottom, children can clearly observe the complete process of the first gear driving the second gear to rotate, and then driving the wheel to rotate. The push rod on the push-pull mechanism can control the transmission between the second gear and the first and third gears, so that the toy has both automatic and manual modes, enriching the ways to play. It can focus on safety and durability, avoid children's injuries when playing, and also satisfy children's desire for immersive scene experience. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings: Please see Figure 1-7 In this embodiment, a toy car push-pull device includes a car bottom 1 and a car body 2. The car seat 1 is threadedly connected to the car body 2 by bolts. The inner wall of the car bottom 1 is fixedly connected to the support block 3. The inner wall of the support block 3 is rotatably connected to the connecting rod 4. The end of the connecting rod 4 is fixedly connected to the wheel 5. The outer wall of the connecting rod 4 is connected to a push-pull mechanism 6.

[0023] The push-pull mechanism 6 includes a first gear 601, the inner wall of the first gear 601 is fixedly connected to the connecting rod 4, the outer wall of the first gear 601 meshes with the second gear 602, the inner wall of the second gear 602 is rotatably connected to the push rod 603, the inner wall of the push rod 603 is engaged with the locking block 604, and the outer wall of the locking block 604 is fixedly connected to the fixing block 605. The transparent bottom of the car 1 provides an intuitive demonstration of the mechanical transmission, allowing children to clearly observe the complete process of the first gear 601 driving the second gear 602 to rotate, thereby driving the wheels to turn. The push rod 603 on the push-pull mechanism 6 can control the transmission between the second gear 602 and the first gear 601 and the third gear 13, giving the toy both automatic and manual modes, enriching the ways to play, emphasizing safety and durability, preventing injuries to children while playing, and satisfying children's desire for immersive scene experiences.

[0024] The lower end of the fixing block 605 is fixedly connected to the bottom of the vehicle 1. The outer wall of the vehicle body 2 is connected to the anti-collision mechanism 7. The anti-collision mechanism 7 includes a first magnetic block 701. The outer wall of the first magnetic block 701 is fixedly connected to the vehicle body 2. The outer wall of the first magnetic block 701 is attracted to the second magnetic block 702. The outer wall of the magnetic block 701 is fixedly connected to the rubber block 703. The outer wall of the rubber block 703 is fixedly connected to the anti-collision block 704.

[0025] The surface of the chassis 1 is fixedly connected to the connecting block 8. The outer wall of the connecting block 8 is fixedly connected to the spring 9. The end of the spring 9 is pressed against the push rod 603. The surface of the chassis 1 is threadedly connected to the mounting frame 10 by bolts. The inner wall of the mounting frame 10 is fixedly connected to the servo motor 11. The output end of the servo motor 11 is fixedly connected to the round rod 12. The outer wall of the round rod 12 is rotatably connected to the mounting frame 10. The end of the mounting frame 10 is fixedly connected to the third gear 13. The end of the third gear 13 meshes with the second gear 602.

[0026] Working principle: First, the rubber block 703 on the anti-collision block 804 is inserted into the groove of the vehicle body 2, and the second magnetic block 702 on the rubber block 703 is attracted to the first magnetic block 701, so that the anti-collision block 804 is installed at the front end of the vehicle body 2. When it collides with other toy cars, the magnetic blocks and the rubber block 703 will produce a buffering effect, reducing the probability of damage to the front end of the vehicle body 2. At the same time, the vehicle body 2 can be used to quickly assemble multiple vehicles (similar to the function of a real train coupler), expanding the play scenarios.

[0027] By pushing the push rod 603 inward with a finger, the locking block 604 on the fixing block 605 inside the push rod 603 will engage in the locking groove of the push rod 603, causing the second gear 602 at the end of the push rod 603 to disengage from the first gear 601. Simultaneously, the push rod 603 compresses the spring 9, causing it to contract. When the child pushes the vehicle body 2, the rolling of the wheels 5 against the ground causes the connecting rod 4 on the support block 3 at the lower end of the vehicle body 2 to be driven by the wheels 5, resulting in a forward and backward movement of the vehicle body 2 and the vehicle base 1. At the same time, by pushing the push rod 603 inward again with a finger, the locking block 604 on the fixing block 605 inside the push rod 603 will engage in the locking groove of the push rod 603. 4 will disengage from the slot of push rod 603. While the locking block 604 is squeezed and deformed, the spring 9 provides a restoring force to push rod 603, causing push rod 603 to return to its original position. The outer wall of the second gear 602 meshes with the first gear 601 and the second gear 602. When the child pushes the car body 2 again, the battery in the bottom 1 of the car provides power to the servo motor 11. The servo motor 11 in the mounting frame 10 will provide power to the round rod 12. The meshing of the third gear 13 with the second gear 602 enhances the transmission efficiency, enabling the toy car to achieve the effect of power assistance, which not only improves the interactivity and fun of the toy.

[0028] 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.
