Referring to fig. 1 to 7, the present embodiment provides a wheel 01 for a child vehicle, which includes a wheel frame structure 100, a hub structure 200 disposed inside the wheel frame structure 100, and a tread 4 disposed outside the wheel frame structure 100.

In the present embodiment, in the wheel frame structure 100, the inner ring of the wheel frame structure 100 has a buckling portion 1, and the buckling portion 1 is used for buckling with a buckling portion 2 formed on the outer ring of the wheel hub structure 200, so as to achieve the detachable connection between the wheel frame structure 100 and the wheel hub structure 200. The wheel frame structure 100 is formed by splicing a first sub wheel frame 110 and a second sub wheel frame 120, and the first sub wheel frame 110 and the second sub wheel frame 120 are identical in structure 100. The first sub wheel frame 110 and the second sub wheel frame 120 are both frame structures 100. The wheel frame structure 100 has a plurality of hollow areas therein. At least one first sub-buckling platform 11 is formed on the inner ring of the first sub-wheel frame 110, at least one second sub-buckling platform 12 is formed on the inner ring of the second sub-wheel frame 120, and the buckling platforms 1 are formed by the first sub-buckling platform 11 and the second sub-buckling platform 12 in a one-to-one correspondence manner. The inner ring of the first sub wheel frame 110 and the inner ring of the second sub wheel frame 120 each have a first groove 13. The number of the first grooves 13 is multiple and the first grooves are evenly distributed. The outer ring of the first sub wheel frame 110 and the outer ring of the second sub wheel frame 120 are provided with a second groove 14. The number of the second grooves 14 is multiple and the second grooves are evenly distributed.

In this embodiment, the outer circle of the hub structure 200 is provided with a buckling portion 2, and the buckling portion 2 is used for buckling with a buckling platform 1 formed by the inner circle of the wheel frame structure 100, so as to achieve the detachable connection between the hub structure 200 and the wheel frame structure 100. The number of the buckling positions 2 is a plurality of and the buckling positions are uniformly distributed. The buckling position 2 is of a reverse buckling structure. The reverse buckling structure includes a first protruding portion 21 and a second bending portion 22 extending to the end of the first protruding portion 21. The first protrusion is perpendicular to the second bending portion 22. The first protrusion is integrally formed with the second bending portion 22. The opening of the inverted button structure faces away from the center point of the hub structure 200.

In the wheel 01 of the child vehicle, the wheel frame structure 100 is integrally split into two upper and lower components, the materials are still common materials in the market, the connection surfaces of the upper and lower components adopt a structure that the hole positions are matched with the rubber columns, and the interiors of the upper and lower components are hollow, so that the weight of the whole wheel frame structure 100 and the consumption of the materials are reduced; the contact part of the wheel frame structure 100 and the tread 4 adopts a concave-convex structure, a circle of the side surfaces of the first sub wheel frame 110 and the second sub wheel frame 120 is provided with a through hole structure to replace a barb rubber column structure on the previous wheel frame structure 100, and a buckling position 2, specifically a reverse buckling structure, is arranged in the wheel frame structure 100.

After the wheel frame structure 100 is produced, the upper assembly and the lower assembly are directly assembled together, the assemblies can be directly placed into a mold by a manipulator, tread materials enter through holes in the two wheel frame assemblies and concave surfaces on the wheel frame assemblies for encapsulation through pressurization, namely the combination of the wheel frame structure 100 and the tread 4 reduces the midway operation processing time.

The central wheel foot arc structure 200 adopts a conventional injection molding processing mode, the middle wheel foot arc structure 200 can be replaced from the aspects of appearance and structure on the premise of not changing the size of the wheel frame structure 100 according to the requirements of customers, after a customer can purchase a set of complete wheel 01, the middle wheel foot arc structure 200 can be directly purchased by a manufacturer if the subsequent wheel foot arc structures 200 with other appearances need to be replaced, and the trouble of replacing the whole set of wheel 01 is saved.

The tire tread 4 is made of a brand new environment-friendly TPR material, has good toughness and wear resistance, and if the existing wheel 01 processing mode is adopted to use the wheel 01 with the same size, the novel wheel 01 structure saves more materials.

Fixing manner of the wheel frame structure 100 and the tread 4:

the assembled wheel frame structure 100 is placed into a forming mold, the tread 4 material is filled into the holes on the wheel frame structure 100 by pressurization and is fused into the concave grooves on the surface of the wheel frame structure 100, so that the tread 4 material is completely contained and fixed with the wheel frame structure 100.

The whole set of wheel 01 mould is completed by three moulds of a wheel frame structure 100 (two moulds are formed by one mould), a wheel hub structure 200 and a rubber-coated tread 4, manual operation and limited production equipment (mould tonnage) are saved in the middle, and automatic production can be completely realized.

The hub structure 200 in the middle of the wheel 01 is not limited under the same specification, and can be replaced and produced into different types and appearances.

The wheel 01 is convenient to replace, and the whole wheel is not required to be replaced due to damage of one part, so that the cost waste is reduced.

The rear front wheel of the completed integral and internal hub structure 200 can be fixed by riveting.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
