A puncture resistant tire structure

Abstract

This invention provides a puncture-resistant tire structure, comprising an inner buffer layer, a puncture-resistant layer, and an outer buffer layer. The puncture-resistant layer is fixed to the outer surface of the inner buffer layer, and the outer buffer layer is fixed to the outer surface of the puncture-resistant layer. The cross-sectional shape of the inner buffer layer, the puncture-resistant layer, and the outer buffer layer is U-shaped. The inner buffer layer reduces the squeezing effect of external forces on the inner tube during use, and also slows down the heating rate of the tire. Furthermore, the puncture-resistant layer prevents punctures by external objects, thus avoiding damage to the inner tube.

Description

Technical Field

[0001] This utility model belongs to the field of tire technology, and in particular relates to a puncture-resistant tire structure. Background Technology

[0002] As the part of the tire that directly contacts the ground, the outer tire bears the key functions of load-bearing, traction, driving, and braking, and its performance directly affects the safety and service life of the vehicle. Currently, most common tire structures on the market adopt a single-layer or double-layer composite design, typically consisting of a rubber carcass, ply layers, and surface tread patterns. The ply layers enhance the strength of the tire carcass, the rubber carcass provides basic cushioning and wear resistance, while the surface tread patterns are responsible for water drainage and grip.

[0003] However, existing tire structures have the following drawbacks in actual use: First, in terms of cushioning performance, although traditional solid rubber cushioning layers can provide a certain shock absorption effect, they cannot effectively disperse pressure when faced with concentrated external force compression, which can easily lead to damage to the inner tube. In addition, rubber materials have high thermal conductivity, and the tire temperature rises significantly after long-term driving, accelerating rubber aging. Furthermore, existing tire structures lack a puncture-resistant layer, which means that when punctured by a foreign object, a penetrating wound will form, thus losing its protective function.

[0004] Therefore, it is essential to invent a puncture-resistant tire structure. Utility Model Content

[0005] To address the above problems, this utility model proposes a puncture-resistant tire structure, and the technical solution used is as follows:

[0006] A puncture-resistant tire structure includes an inner buffer layer, a puncture-resistant layer, and an outer buffer layer. The puncture-resistant layer is fixed to the outer side of the inner buffer layer, and the outer buffer layer is fixed to the outer side of the puncture-resistant layer. The cross-sectional shape of the inner buffer layer, the puncture-resistant layer, and the outer buffer layer is U-shaped.

[0007] Furthermore, the inner buffer layer includes a first layer and an annular cavity. The first layer is fixed to the inner side of the puncture-resistant layer, and a plurality of annular cavities are uniformly formed inside the first layer. The annular cavities are filled with inert gas. This arrangement can reduce the squeezing effect of external force on the inner tube and, secondly, reduce the heating rate of the outer tire.

[0008] Furthermore, the puncture-resistant layer includes a second layer and a reinforcing mesh. The second layer is fixed between the inner buffer layer and the outer buffer layer, and at least two reinforcing meshes are fixed inside the second layer. The reinforcing meshes are all made of high-strength yarns woven into a mesh structure, and the central mesh holes inside adjacent reinforcing meshes are staggered. This arrangement can block the puncture of foreign objects.

[0009] Furthermore, the outer surface of the outer buffer layer is provided with a number of transverse and longitudinal patterned grooves, wherein the transverse and longitudinal patterned grooves are arranged perpendicular to each other. With this arrangement, the longitudinal patterned grooves can guide the vehicle's driving direction, drain water and increase friction. Secondly, the transverse patterned grooves can help cut the water film and enhance the drainage effect.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The inner buffer layer of this utility model has the following effect: when an external force compresses the outer tire, the puncture-resistant layer at this location will compress the first layer, causing the annular cavity to deform, thereby reducing the compression effect of the external force on the inner tire. Secondly, the inert gas inside the annular cavity will reduce the heating rate of the outer tire.

[0012] 2. The puncture-resistant layer of this utility model can block the puncture of the inner tube when the outer tire is punctured by a foreign object through the cooperation of multiple reinforcing meshes (even if the foreign object punctures a single reinforcing mesh, the remaining reinforcing meshes can still block the foreign object), thereby preventing the foreign object from damaging the inner tube.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Please see Figures 1 to 4 As shown, this utility model is a puncture-resistant tire structure, including an inner buffer layer 1, a puncture-resistant layer 2 and an outer buffer layer 3. The puncture-resistant layer 2 is fixed to the outer side of the inner buffer layer 1, and the outer buffer layer 3 is fixed to the outer side of the puncture-resistant layer 2. The cross-sectional shape of the inner buffer layer 1, the puncture-resistant layer 2 and the outer buffer layer 3 are all "U" shaped.

[0023] Specifically, the inner buffer layer 1 includes a first layer 11 and an annular cavity 12. The first layer 11 is fixed to the inner side of the puncture-resistant layer 2, and a plurality of annular cavities 12 are uniformly formed inside the first layer 11. The annular cavities 12 are filled with inert gas (nitrogen or helium). With this arrangement, when an external force compresses the outer tire, the puncture-resistant layer 2 at this position will compress the first layer 11, causing the annular cavity 12 to deform, thereby reducing the compression effect of the external force on the inner tire. Secondly, the inert gas inside the annular cavity 12 will reduce the heating rate of the outer tire.

[0024] Specifically, the puncture-resistant layer 2 includes a second layer 21 and a reinforcing mesh 22. The second layer 21 is fixed between the inner buffer layer 1 and the outer buffer layer 3, and at least two layers of reinforcing mesh 22 are fixed inside the second layer 21. The reinforcing mesh 22 is a mesh structure woven from high-strength yarn (aramid fiber or ultra-high molecular weight polyethylene), and the central mesh holes inside adjacent reinforcing mesh 22 are staggered. With this arrangement, when the outer tire is punctured by a foreign object, the puncture is blocked by the cooperation of multiple reinforcing mesh 22 (even if the foreign object punctures a single layer of reinforcing mesh 22, the remaining reinforcing mesh 22 can still block the foreign object), thereby preventing the foreign object from damaging the inner tire.

[0025] Specifically, the outer buffer layer 3 has several transverse patterned grooves 4 and longitudinal patterned grooves 5 on its outer surface. The transverse and longitudinal patterned grooves are arranged perpendicular to each other. When in use, the longitudinal patterned grooves 5 can guide the vehicle's driving direction, drain water, and increase friction. Secondly, the transverse patterned grooves can help cut the water film and enhance the drainage effect.

[0026] Please see Figure 1-4 As shown, this utility model is a puncture-resistant tire structure. Its working principle is as follows: after being fixed to the tire wheel body, the inner buffer layer 1 can reduce the shock of the tire and reduce the tire's heating rate. Secondly, the puncture-resistant layer 2 can block foreign objects from puncturing, thereby preventing foreign objects from damaging the inner tube. In addition, the transverse tread grooves 4 and longitudinal tread grooves 5 can increase the friction between the outer buffer layer 3 and the ground.
