Novel wheel

Abstract

The invention discloses a novel wheel. A wheel body is integrally formed by the 3D printing technology, the process is simple, and the inside of the wheel body is of a honeycomb structure, which not only reduces the product quality but also enhances the strength of the product; the wheel body is sequentially provided with a tire part, a spoke part and an axle part from outside to inside, the outerside of the spoke part is connected with the inner side of the tire part, the inner side of the spoke part is connected with the outer side of the axle part, and the spoke part achieves a supportingeffect on the tire part; the tire part, the spoke part and the axle part are each made of a TPU material, the rigidities increase sequentially, and the tire part has the lowest rigidity and has high elasticity and wear resistance; the spoke part has moderate rigidity, thereby not only achieving a transition buffering effect and reducing the vibration on the axle part, but also improving the strength of the tire part and preventing the tire part from being deformed; the axle part has the highest rigidity, is connected with the axle, and has high mechanical strength; and in addition, the middleof the spoke part is inwards contracted so that the side end face of the spoke part is sunken inwards, thus an effect of anti-deformation is achieved, the mechanical strength of the spoke part is enhanced, the service life of the wheel body is prolonged, and the security is high.

Description

technical field [0001] The invention relates to a wheel, in particular to an integrated stroller wheel. Background technique [0002] The wheels of baby carriages in the prior art usually include wheel hubs and tires installed on the wheel hubs. The wheel hubs are generally made of metal or hard plastic materials, which are heavy and inconvenient for the storage and handling of baby carriages; It is made of high-quality materials and has a shock-absorbing effect; due to the different materials of the two, it needs to be assembled through mold production separately in the production process, and the process is cumbersome, resulting in high production costs. [0003] In addition, the hub and the tire are generally connected by buckles, etc. There is a gap between the two, and friction will occur at the contact part during use, which reduces the service life of the tire. After long-term use, the inner side of the tire will be worn, and in severe cases Cause the tire to rupture...

[0002] The wheels of baby carriages in the prior art usually include wheel hubs and tires installed on the wheel hubs. The wheel hubs are generally made of metal or hard plastic materials, which are heavy and inconvenient for the storage and handling of baby carriages; It is made of high-quality materials and has a shock-absorbing effect; due to the different materials of the two, it needs to be assembled separately through mold production during the production process. The process is cumbersome, resulting in high production costs.

[0003] In addition, the hub and the tire are generally connected by buckles, etc. There is a gap between the two, and friction will occur at the contact part during use, which reduces the service life of the tire. After long-term use, the inner side of the tire will be worn, and in severe cases Cause the tire to break off and fall off, poor safety
