[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] For example, Figure 1 And Figure 3As shown, a new tire structure, which can be combined with the rim 7, the structure comprises the inner tire 1, the protective layer 2 and the outer tire 3, the protective layer 2 is arranged between the inner tire 1 and the outer tire 3, the inner surface of the protective layer 2 is provided with a plurality of reinforcing ribs 4 at equal intervals along the length direction on both sides, and the reinforcing rib 4 and the protective layer 2 are integrally formed, both are made of the same material, the reinforcing rib 4 is used to support the protective layer 2 to reduce its deformation, and the surface of the inner tire 1 is in abutment with the reinforcing rib 4;

[0023] The reinforcing rib 4 can significantly improve the compressive strength of the protective layer 2. When the tire is impacted by external force or pressed by heavy objects, the reinforcing rib 4 can disperse and absorb these pressures, preventing the protective layer 2 from deforming and pressing the inner tire 1, which can cause damage to the inner tire 1. At the same time, since the reinforcing rib 4 enhances the structural strength of the protective layer 2, if the inner tire 1 is accidentally penetrated and damaged, the reinforcing rib 4 can also well support the protective layer 2 to reduce its deformation, so that the outer tire 3 can maintain its original shape and elasticity for a period of time, facilitating the user to continue moving to the repair point;

[0024] The reinforcing rib 4 plate can reduce the friction and wear between the puncture-proof layer and the inner tire 1. Due to the presence of the reinforcing rib 4 plate, it can play a limiting and restraining role on the inner tire 1 to prevent the inner tire 1 from sliding relative to the protective layer 2 during use. At the same time, the presence of the reinforcing rib 4 reduces the contact area between the protective layer 2 and the inner tire 1, thereby reducing the friction between them, which helps to reduce the wear of the inner tire 1 and prolong its service life;

[0025] At the same time, the reinforcing rib 4 plate can serve as an additional barrier. If a sharp object penetrates the puncture-proof layer and pierces into the inner tire 1, the reinforcing rib 4 arranged at intervals can play a limiting role on the sharp object, preventing it from moving horizontally with the tire and preventing the object from causing secondary damage to the inner tire 1.

[0026] In this embodiment, the inner surface of the protective layer 2 is provided with (using adhesion, embedding and other methods) a puncture-proof film 5 in the middle, which is in abutment with the middle surface of the inner tire 1, and the puncture-proof film 5 is a TPU film; TPU film has excellent wear resistance, even after long-term use, the surface remains smooth and is not easy to wear. This makes the tire better protect the inner tire 1 during driving, and can avoid excessive friction between the inner tire 1 and the protective layer 2, which can cause the inner tire 1 to tear;

[0027] The TPU film has excellent tear resistance and is not easy to tear even when subjected to external force or impact from sharp objects. Based on the original protective layer 2, the TPU film as a second layer of protection can further block the penetration of sharp objects and provide more comprehensive protection. Even if the protective layer 2 is slightly pierced, the TPU film can continue to function to prevent the tire from leaking or being damaged.

[0028] In the embodiment, the outer surface of the protective layer 2 is provided with a plurality of convex points 6, and the convex points 6 are integrally formed with the protective layer 2; the convex points 6 can increase the contact area and friction between the protective layer 2 and the outer tire 3, so that the connection between the two is more closely and firmly;

[0029] The convex points 6 can disperse the pressure and impact force received by the tire during driving. When the tire is in contact with the ground, the convex points 6 can uniformly disperse the pressure between the protective layer 2 and the outer tire 3, reduce the local pressure concentration, and thus reduce the risk of deformation or damage of the tire due to excessive pressure

[0030] At the same time, the presence of the convex points 6 is equivalent to forming an additional protective barrier between the protective layer 2 and the outer tire 3. When a sharp object contacts the tire, the convex points 6 can first block and disperse the impact force of the object, reducing the possibility of the object penetrating the outer tire 3 and the protective layer 2 directly.

[0031] In the embodiment, the middle part of the outer tire 3 has a greater thickness than other parts. The part of the tire in contact with the ground is the most severely worn area, and increasing the thickness of this part can significantly improve the wear resistance of the tire. The thicker tread can withstand more friction and wear.

[0032] Referring to Figure 1 The embodiment also provides a wheel, which comprises a rim 7 and the tire structure described above. The lower end of the outer tire 3 and the lower end of the protective layer 2 are wrapped below the inner side of the outer end edge of the rim 7. The lower part of the rim 7 is provided with a valve, and the inner end of the valve is in communication with the inner tire 1. Wrapping the lower end of the outer tire 3 and the protective layer 2 inside the rim 7 can prevent the inner tire 1 from being wound between the outer tire 3 and the protective layer 2 when the tire rolls during driving, so that the inner tire 1 is torn and the tire bursts.

[0033] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
