Description

Technical Field

[0001] This invention relates to the field of vehicle tire technology, and more specifically to an explosion-proof tire. Background Technology

[0002] If a traditional pneumatic tire is punctured by a sharp object on the road, the air inside the tire will leak out rapidly, causing the vehicle to lose control and stability, and in severe cases, potentially leading to a traffic accident. To address the tire blowout problem, various solutions have been proposed, such as solid tires, run-flat tires, and multi-chamber tires.

[0003] However, solid tires offer poor comfort; run-flat tires have limited mileage and are expensive after a puncture; and while existing multi-chamber tires can separate the gas into multiple independent spaces, there is a lack of effective collaborative protection mechanisms between the various airbag units. After a sharp object punctures the tire's external structure, it can easily puncture adjacent airbags, causing multiple airbags to fail simultaneously and significantly reducing the puncture protection effect. Summary of the Invention

[0004] To address the technical shortcomings of existing run-flat tires, which are still prone to damage to the internal air bladder structure and overall tire failure after being punctured by sharp objects, this invention provides a novel run-flat tire, employing the following technical solution:

[0005] An explosion-proof tire includes a tire body, characterized in that: the tire body contains a plurality of air bladders. The number and diameter of the air bladders can be adjusted according to the tire model. Each air bladder has an annular wound groove, within which Kevlar wire is wound, wrapping and protecting the outer surface of the air bladder. Due to the special properties of Kevlar wire, it is five times stronger than steel of the same weight, yet as flexible as ordinary fabric. This "combination of strength and flexibility" makes it a key material in many fields. Each air bladder has a fixing buckle, designated as buckle a and buckle b, at both ends for securing the Kevlar wire. The Kevlar wire prevents damage to the air bladder when a sharp object is inserted. Furthermore, a certain gap is provided between every two air bladders, allowing the air bladder to move when a sharp object is inserted, thereby protecting the air bladder structure.

[0006] As a further improvement of the present invention, a lightweight foam layer is provided between the airbag and the inner wall of the tire. The foam layer is used to prevent the entry of sharp objects and plays a preliminary physical blocking and buffering role.

[0007] As a further improvement of the present invention, the airbag has a cylindrical structure and soft cushioning elements are provided on both sides of the airbag. The soft cushioning elements are used to prevent sharp objects from entering and damaging the airbag.

[0008] As a further improvement of the present invention, the soft cushioning element is a hemispherical structure to increase the contact area with the inner wall of the tire and disperse the external extrusion force.

[0009] As a further improvement of the present invention, the airbag is provided with an inflation port for independently inflating a single airbag.

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

[0011] Active yielding and mobile puncture prevention mechanism: By leaving a specific gap between adjacent airbags, when a sharp object punctures, the airbag can undergo slight lateral or sideways displacement, thereby avoiding the direct puncture path of the sharp object. This "soft-to-hard" mobile protection method fundamentally changes the traditional tire "hard-to-resist" puncture mode, greatly improving the probability of puncture prevention.

[0012] High-strength fiber wrapping and local reinforcement: Kevlar wire is tightly wrapped and fixed in the annular groove on the outer surface of the airbag. The high strength and high modulus of Kevlar wire form a tough "local armor" when a sharp object comes into contact with it, effectively blocking or delaying the penetration of the sharp object. At the same time, the groove structure prevents the wrapped wire from slipping off.

[0013] Multi-gradient buffer protection system: This invention constructs a multi-gradient protection system consisting of "tire body → lightweight foam layer → Kevlar cable layer → soft cushioning component → airbag". The foam layer blocks large particles, the Kevlar cables resist puncture force, and the soft cushioning component absorbs impact and protects the weak points on both sides of the airbag. This layered approach greatly enhances the tire's overall damage resistance. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] Please refer to Example 1 Figure 1 , Figure 2 , Figure 3 , Figure 4 This invention provides an explosion-proof tire.

[0019] The explosion-proof tire mainly comprises a flexible tire body 1. Multiple independent and separated airbags 3 are installed within the internal cavity of the tire body 1, and these airbags 3 are arranged along the circumference of the tire. In this embodiment, the airbags 3 are preferably cylindrical to facilitate uniform pressure bearing.

[0020] Between the inner wall of the tire body 1 and the air bladder 3, there is a lightweight foam layer 2. The foam layer 2 is made of microporous polyurethane material, which has good elastic cushioning effect and can prevent small sand or debris from directly contacting the air bladder 3.

[0021] On the outer circumferential surface of each airbag 3, several parallel annular winding grooves 6 are formed. The depth of the annular winding grooves 6 is slightly smaller than the diameter of the Kevlar wire 8, so as to ensure that the Kevlar wire 8 protrudes from the surface of the airbag 3 after winding, forming an effective physical barrier.

[0022] High-strength Kevlar cable 8 is tightly wound into the aforementioned annular winding groove 6, completely covering the main outer surface of the airbag 3. To prevent the Kevlar cable 8 from loosening due to air pressure changes or vibrations during use, fixing buckles a4 and b7 are respectively provided at both ends of the airbag 3. In specific operation, one end of the Kevlar cable 8 can be tied or clipped to the fixing buckle a4, and after winding, the end is pulled tight and fixed to the fixing buckle b7.

[0023] Soft cushioning elements 2 are provided at both ends of the airbag 3. The soft cushioning element 2 is a hemispherical or arc-shaped structure, with its convex surface facing the inner wall of the tire or the adjacent airbag. When a sharp object 9 pierces the airbag, the hemispherical structure can effectively disperse the stress and protect the weak connection area at both ends of the airbag 3.

[0024] The core innovation of this invention lies in the predetermined spacing L between two adjacent airbags 3, typically 5mm-20mm, adjusted according to tire size. When the sharp object 9 penetrates the tire body 1 and the foam layer 2, it first contacts the Kevlar cable 8 on the outside of the airbag 3. If the puncture force is extremely high, the Kevlar cable 8 undergoes elastic deformation and pushes the airbag 3 laterally to the gaps on both sides, thereby "avoiding" the tip of the sharp object 9 and preventing the airbag 3 from being directly punctured.

[0025] The soft buffers 2 at both ends of the airbag 3 are made of oil-resistant rubber or silicone, with their Shore hardness controlled between 40 and 60 degrees to ensure both sufficient support and good deformation energy absorption effect.

[0026] Each airbag 3 is equipped with an inflation port 5, which has a one-way valve structure, allowing users to independently inflate and check the air pressure of each airbag 3. Even if one airbag 3 is damaged and leaks air due to extreme circumstances, the vehicle can still be driven normally. Once the vehicle is safe, simply replenish the air pressure of that airbag 3 or replace it with an additional airbag 3 to ensure the tire's emergency driving capability.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0028] The above description is merely a preferred embodiment of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
