Description

Technical Field

[0001] This utility model relates to the technical field of tires, and more specifically, to a self-healing explosion-proof protection structure inside a tire. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on metal rims, support the vehicle body, buffer external impacts, make contact with the road surface, and ensure the vehicle's driving performance. Tires are the carriers of force transmission between the vehicle and the road surface. Through the tires, driving force, braking force, steering force, etc. are transmitted, thereby realizing the driving, braking, and steering operations of automobiles.

[0003] With the development of the times and the faster pace of social life, people choose cars or public transportation to adapt to the current fast-paced lifestyle. Urban construction also relies heavily on construction vehicles. However, during vehicle use, tires can experience punctures and leaks. Especially in poor road conditions and high temperatures, a puncture can lead to insufficient tire pressure, and continuing to drive may result in a tire blowout. This can cause property damage and safety accidents.

[0004] Therefore, solid tires and puncture-proof / run-flat tires have emerged in the market. While solid tires are durable, they are too heavy and expensive, have poor shock absorption, and are not suitable for various road conditions. Lighter foam-filled solid tires, after a period of use, develop gaps between the foam and the inner lining of the tire, preventing them from springing back and causing unstable contact with the ground, affecting vehicle speed and accelerating tire wear. Puncture-proof / run-flat tires use a layer of rubber sprayed onto the inner lining to prevent air leakage, but this is only effective on the coated bottom. If the puncture is too long or irregular (such as a nail extending too far beyond the coating, rusty nails, glass shards, etc.), it will not provide protection. If the puncture is on the tire sidewall, this type of tire will not be effective. Therefore, they are not the best choice either.

[0005] Based on this, we provide a self-healing explosion-proof protection structure for the inside of a tire.

[0006] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0007] To address the issues that solid tires, while durable, are too heavy and expensive, have poor shock absorption, and are unsuitable for various road conditions, while lighter foam-filled solid tires develop gaps between the foam and the inner bottom of the tire after a period of use, resulting in unstable tire contact with the ground, affecting vehicle speed, and accelerating tire wear, this invention provides a self-healing explosion-proof protection structure inside the tire.

[0008] The present invention provides a self-repairing and explosion-proof protection structure for the internal structure of a tire, which adopts the following technical solution:

[0009] A self-healing explosion-proof protection structure for tire interiors includes a tire and an explosion-proof sticker disposed on the inner wall of the tire to prevent tire blowout.

[0010] Preferably, the explosion-proof sticker is completely fitted to the inner wall of the tire.

[0011] Preferably, the explosion-proof sticker includes an outer adhesive layer, a first foam layer, a mesh tensile layer, and a second foam layer.

[0012] Preferably, the outer rubber layer is disposed on the inner wall of the tire, the first foam layer is laid on the side of the outer rubber layer, the mesh tensile layer is laid on the side of the first foam layer, and the second foam layer is laid on the side of the mesh tensile layer.

[0013] Preferably, a layer of adhesive is applied between the outer rubber layer and the inner wall of the tire.

[0014] By adopting the above technical solution, after a tire is punctured, the damaged area can be automatically repaired and leak-proofed. At the same time, it can also avoid gaps between the foam and the tire, thus making the tire not only puncture-proof but also providing excellent riding comfort and safety.

[0015] Preferably, the outer adhesive layer is a polymer composite adhesive.

[0016] Preferably, the first foam layer and the second foam layer are PU foam.

[0017] Preferably, the mesh tensile layer is a mesh fabric.

[0018] In summary, this utility model has the following beneficial technical effects:

[0019] By installing explosion-proof stickers all over the inner wall of the tire and applying self-adhesive to the inner wall beforehand, the tire can be fully protected against explosions. After the tire is punctured, the damaged area can be automatically repaired and leak-proofed. At the same time, it can also avoid gaps between the foam and the tire. As a result, the tire not only has explosion-proof effect but also has good riding comfort and safety.

[0020] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the invention will become readily apparent from the accompanying drawings and the following detailed description.

[0029] Example 1

[0030] This utility model discloses a self-repairing explosion-proof protection structure for the internal structure of a tire. (Refer to...) Figures 1 to 3A self-healing explosion-proof protection structure for tire interiors includes a tire 1 and an explosion-proof sticker disposed on the inner wall of the tire 1 to prevent the tire 1 from bursting.

[0031] Specifically, the explosion-proof sticker is designed to completely adhere to the inner wall of tire 1.

[0032] Specifically, the explosion-proof sticker includes an outer adhesive layer 2, a foam layer 1 3, a mesh tensile layer 4, and a foam layer 2 5.

[0033] Specifically, the outer rubber layer 2 is disposed on the inner wall of the tire 1, the first foam layer 3 is laid on the side of the outer rubber layer 2, the mesh tensile layer 4 is laid on the side of the first foam layer 3, and the second foam layer 5 is laid on the side of the mesh tensile layer 4.

[0034] Specifically, an adhesive layer is applied between the outer rubber layer 2 and the inner wall of the tire 1. The adhesive is the kind used in explosion-proof tires on the market, such as self-adhesive, self-healing adhesive, natural rubber, etc. Self-adhesive is preferred in this application.

[0035] like Figure 2 and Figure 3 As shown, by installing explosion-proof stickers all over the inner wall of the tire and applying self-adhesive to the inner wall of the tire beforehand, the tire can be fully protected against explosions. After the tire is punctured, the damaged area can be automatically repaired and leak-proofed. At the same time, it can also avoid gaps between the foam and the tire. Thus, the tire not only has explosion-proof effect but also has good riding comfort and safety.

[0036] Specifically, the outer rubber layer 2 can be a polymer composite material, specifically butyl rubber.

[0037] Specifically, foam layer 3 and foam layer 5 are PU foams, and the material of the foam layer can be EPS, EVA, etc., with EVA material being preferred in this utility model.

[0038] Specifically, the mesh tensile layer 4 can be a mesh fabric, fine steel wire, or nylon mesh, specifically a nylon mesh.

[0039] Comparative Example 1

[0040] like Figure 4 As shown, this is a common pneumatic tire on the market. When punctured, it deflates quickly, making the electric scooter unusable.

[0041] Comparative Example 2

[0042] like Figure 5 As shown, foam-filled tires currently on the market will develop gaps between the foam material and the inner wall of the tire after a period of riding, making it unable to rebound. As a result, the tire will contact the ground, leading to unstable speed and accelerated tire wear.

[0043] The comparison yields the following table:

[0044]

[0045] As can be seen from the table above, the tire of this invention has significant advantages in terms of explosion-proof capability, comfort, and service life compared to ordinary tires or explosion-proof tires on the market. The tire of this invention has self-repair and leak-proof effects, and can also protect the inner wall of the tire sidewall, thus comprehensively improving the tire's explosion-proof performance.
