[0015] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0016] In order to solve the above technical problems, Figure 1-3As shown, the utility model designs a silent and shock-absorbing child wheel, including a mounting plate 1, a movable plate 2, a support rod 3, a wheel hub 4, and a tire 5. Side plates 6 are symmetrically arranged at the left and right ends below the mounting plate 1, and a support plate 7 is arranged between the two side plates 6 to form a solid supporting structure, which not only enhances the overall stability of the child wheel, but also provides better load-bearing capacity. The side plates 6 are L-shaped, and a convex limit block 8 is provided in the middle part of the movable plate 2. A limit hole cooperating with the limit block 8 is provided at the lower extension part of the side plate 6. The movable plate 2 is rotatably connected to the side plate 6 through the limit block 8, allowing the movable plate 2 to rotate freely within a certain range, thereby adapting to different road conditions.

[0017] A first connecting shaft 9 is provided at the front end of the movable plate 2, and a second connecting shaft 10 is provided at the rear end of the movable plate 2. The bottom end of the support rod 3 is connected to the second connecting shaft 10, and the top end of the support rod 3 passes through the through hole of the support plate 7 and is connected to the limit nut. A shock-absorbing spring 11 is provided on the outer side of the support rod 3 to form an effective shock-absorbing mechanism. When the wheel encounters a bumpy road surface, the shock-absorbing spring 11 can absorb the impact energy, reduce the vibration transmitted to the vehicle body, and improve the ride comfort.

[0018] The first connecting shaft 9 is connected to the wheel hub 4, the tire 5 is arranged on the outside of the wheel hub 4, and a plurality of porous sound-absorbing blocks 12 are arranged on the inner side of the carcass of the tire 5. Preferably, a plurality of the porous sound-absorbing blocks 12 are evenly spaced along the circumferential direction, and the porous sound-absorbing blocks 12 are bonded to the inner tread of the tire 5 through an adhesive layer. The porous sound-absorbing blocks 12 are made of open-cell foam or microporous rubber material, and utilize their porous structure to effectively absorb the vibration and noise inside the tire 5, thereby significantly reducing the noise generated during driving and providing a quieter and more comfortable riding environment for children.

[0019] It is further preferred in this embodiment that the outer tread of the tire 5 is provided with a plurality of trapezoidal protrusions 13, and the plurality of trapezoidal protrusions 13 are distributed in a circular array, which not only enhances the wear resistance of the tire 5, but also optimizes the contact between the tire 5 and the ground through the circumferential array distribution, improves the grip and handling stability of the tire 5, and also helps to drain water, thereby improving the performance of wet driving.

[0020] In this embodiment, it is further preferred that a mounting hole 14 is respectively provided at the four corners of the mounting plate 1, and the mounting hole 14 is used to cooperate with the frame, providing a convenient installation method, so that the tire 5 and the frame are more quickly and firmly connected. This design simplifies the assembly and maintenance process of the baby carriage and improves the convenience of use.

[0021] Through a series of innovative designs, this wheel not only significantly improves the riding comfort and quietness of the baby stroller, but also enhances the durability and convenience of installation of the tire 5. The combination of the porous sound-absorbing block 12 and the shock-absorbing spring 11 effectively reduces driving noise and vibration. The design of the trapezoidal protrusion 13 improves the grip and wear resistance of the tire 5, ultimately making the baby stroller wheel a high-performance, high-comfort baby stroller accessory.

[0022] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made by technicians in the relevant technical field based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
