Description

Technical Field

[0001] This utility model relates to the field of wheels, specifically to a tire that is explosion-proof and prevents tire air leakage. Background Technology

[0002] The wheel is a major component supporting the vehicle chassis and enabling movement. Generally, a wheel consists of a hub, spokes, and rim. The rim mounts and supports the tire, and the hub and rim are fixedly connected by the spokes. Due to the integration of hub, spokes, and rim, many people now consider the wheel and hub to be the same object. For example, the term "hub" in the Chinese patent publication CN209274284U, titled "Explosion-proof Tire Hub, Explosion-proof Tire and Mobile Tool," is the same as the commonly used term "wheel." With the gradual improvement of living standards, more and more people own cars, and cars have gradually become essential for daily travel and transporting goods. Tire is a major mode of transportation, and people's demands for driving safety are constantly increasing. However, the issue of tire safety has not been effectively resolved. When a car tire blows out or leaks air, the tire immediately loses its support, causing the vehicle to lose balance and leading to a car accident. This has become a major hidden danger to vehicle safety. According to statistics, more than 40% of highway traffic accidents in China are caused by tire problems, with tire blowouts being the most serious, accounting for 70%. This poses a significant threat to personal safety and causes significant losses to personal property. Therefore, how to prevent tire blowouts and leaks has become an urgent need.

[0003] To address this, several solutions have been proposed, such as run-flat tires, run-flat tire wheels (or rims), and run-flat tire rims. However, these solutions have not yet fundamentally solved the problem. For example, Chinese patent literature, specifically utility model patent publication (authorization announcement number) CN209274284U, discloses "Run-flat tire rims, run-flat tires, and mobile tools," which addresses some existing industry problems. However, the technical solution in this document has some significant flaws:

[0004] 1. In the aforementioned document and its accompanying drawings, the document states, "

[0012] Further, the explosion-proof raised guard ring includes an elastic element, the elastic element is located at the end of the explosion-proof raised guard ring, and the distance from the elastic element to the central axis is L1.

[0013] Further, the explosion-proof raised guard ring is also provided that the elastic element is fixed in the mounting groove." The phrase "the explosion-proof raised guard ring includes an elastic element, the elastic element is located at the end of the explosion-proof raised guard ring" does not specify that the end of the "elastic element" must be higher than the end of the "mounting groove." Since the "elastic element" is an elastic object, when the tire suddenly bursts, the tire quickly squeezes the "elastic element," causing the "elastic element" to lose its supporting function. Therefore, the design of the "elastic element" has a significant defect.

[0005] 2. The ultimate purpose of the document is that the technical solution described in the document

[0018] , which states that "when an aircraft, vehicle, or other means of transportation experiences an explosion or instantaneous decompression during operation, the distance L1 from the upper end of the explosion-proof raised guard ring to the central axis is greater than the distance L2 from the upper end of the bent portion to the central axis. Therefore, the explosion-proof raised guard ring reduces the distance between the entire wheel hub and the ground during a tire blowout, thus smoothly replacing the outer tire and directly contacting the ground," cannot be achieved. Furthermore, the document cannot achieve the purpose of the "explosion-proof raised guard ring" and "replacing the outer tire and directly contacting the ground." The "explosion-proof raised guard ring" is located inside the tire. When the tire blows out, it doesn't directly "explode" and fly away, causing the tire to detach from the wheel hub. Therefore, it cannot achieve the goal of the "explosion-proof raised guard ring" replacing the outer tire and directly contacting the ground. It can only achieve direct contact between the inner end of the tire and the outer end of the "explosion-proof raised guard ring" after the tire blows out.

[0006] Therefore, it is evident that the aforementioned document has significant flaws, and the technical solution described in the document cannot be implemented.

[0007] For example, in Chinese patent literature, utility model patent publication (authorization announcement number) CN201158279Y discloses "Explosion-proof tire rims," ​​which solves some problems currently existing in the industry. However, the technical solution in this document has some major defects:

[0008] 1. The document and its accompanying drawings, specifically the section [2, Technical Solution] of the document [(III) Invention Content:], state that "the technical solution of this utility model is: a rim for explosion-proof tires, comprising a rim and spokes, characterized in that an explosion-proof tire is present on the outer periphery of its rim." However, the description of "a rim for explosion-proof tires, comprising a rim and spokes" fails to explain the purpose and connection method of "rim and spokes." Furthermore, the term "rim" in "rim for explosion-proof tires" is identical to the term "rim," making the terminology in the document ambiguous and obscuring its technical solution. Therefore, the document's description has significant flaws.

[0009] 2. The description in the document and its accompanying drawings, specifically in the section [2. Technical Solution] of document [(III) Summary of the Invention:], states that "its characteristic is that it has a run-flat tire on the outer periphery of its rim." This directly contradicts the description in document [(V) Specific Embodiment:] that "it includes a rim 3 and a conventional tire 2 mounted on the periphery of the rim 3, and a run-flat tire 1 also mounted on the periphery of the rim 3 and enclosed within the conventional tire 2." The phrase "a run-flat tire on the outer periphery of the rim" and "a run-flat tire 1 also mounted on the periphery of the rim 3 and enclosed within the conventional tire 2" directly conflict with the description in document [(V) Specific Embodiment:], making it impossible to understand how the technical solution is implemented. The description in the document has significant flaws.

[0010] 3. In the aforementioned document and its accompanying drawings, the document [(V) Specific Embodiments:] states that "it has an explosion-proof tire on the outer periphery of its rim. The explosion-proof tire wheel of this utility model is an elastic solid tire with an outer diameter smaller than that of a commonly used tire." However, it does not specify that the outer diameter of the "elastic solid tire" is larger than the outer diameter of the "rim." This technical solution would result in the "elastic solid tire" losing its supporting function when its outer diameter is smaller than or equal to the outer diameter of the "rim," failing to fully achieve the purpose of the explosion-proof tire supporting the vehicle and preventing it from overturning when a commonly used tire leaks air or bursts. Therefore, the design of the "elastic solid tire" has a significant defect.

[0011] 4. The "explosion-proof tire" mentioned in the literature and its accompanying drawings, specifically in the literature [(V) Specific Implementation:] which states that "the combination of the explosion-proof tire and the rim 3 is achieved by heat sealing, bonding, or by relying on the tension of the explosion-proof tire itself," is an elastic solid tire. The "rim 3" lacks necessary fixing components, and the elastic "explosion-proof tire" and "rim 3" cannot be effectively fixed by heat sealing, bonding, or relying on the tension of the explosion-proof tire itself through their contact surface. Therefore, the literature has significant flaws.

[0012] Therefore, it is evident that the aforementioned document has significant flaws, and the technical solution described in the document cannot be implemented.

[0013] For example, Chinese patent literature, specifically utility model patent publication (authorization announcement number) CN207594654U, discloses "A Safe Runaway Tire Automobile Wheel," which solves some existing problems in the industry. However, the technical solution in this document has some significant flaws:

[0014] 1. The document and its accompanying drawings, specifically document

[0006] , describe a technical solution in a simple sentence: "The safety support includes a base hard rubber layer and an elastic surface rubber layer connected to the base hard rubber layer; the base hard rubber layer is fixed to the middle position of the outer surface of the rim by bolts." However, this is difficult to implement. Firstly, there are only two ways to fix the "base hard rubber layer" and the "outer surface of the rim" by bolts. One way is to add several bolt holes to the "rim," which damages the strength of the "rim," increases the possibility of air leakage, and greatly increases the safety hazard. This technical solution has a major flaw. The second way is to have several nut-like structures on the "outer surface of the rim," and then fix the "base hard rubber layer" and the "outer surface of the rim" by screws. This contradicts document

[0008] 's description of "the safety support is a continuous annular structure or a discontinuous protruding structure," specifically the statement "the safety support is a continuous annular structure." One interpretation of the aforementioned document is that the "base hard rubber layer" is a solid tire structure, and its height and width must not be too far from the tire's clearance, otherwise it will not be able to support the tire. Furthermore, the area of ​​the "base hard rubber layer" cannot be too small. However, modern car wheels are mostly integrated structures, with the outer diameter of the "rim" being larger than the inner diameter of the "base hard rubber layer." The solid tire structure of the hard rubber layer is almost impossible to stretch under normal conditions, and even with heating, installation is difficult. Moreover, it must be accurately aligned with the bolt holes on the "rim's outer surface," making it even more challenging. Therefore, the design of the "safety support" has significant flaws.

[0015] 2. The document and its accompanying drawings mentioned above, in the document

[0006] , the statement that "the base hard rubber layer is fixed to the middle position of the outer surface of the rim by bolts" can be understood as the bottom surface of the "base hard rubber layer" and the contact surface of the "outer surface of the rim" being fixed by bolts. This fixing method makes it difficult to completely fix the "base hard rubber layer" so that it does not tilt under the pressure of a tire blowout. This technical solution has some major defects.

[0016] 3. In the aforementioned document and its accompanying drawings, the document

[0007] states that "the height and width of the safety support body are less than the inner diameter of the car tire;" but does not specify that the outer diameter of the "safety support body" is greater than the outer diameter of the "rim". This technical solution may result in the outer diameter of the "safety support body" being lower than or equal to the outer diameter of the "rim". In this case, the "safety support body" loses its supporting function and cannot fully achieve the purpose of supporting the car and preventing the vehicle from overturning when the tire leaks air or bursts. Therefore, the setting of the "safety support body" has a major defect.

[0017] 4. Regarding the aforementioned document and its accompanying drawings, the document

[0006] states that "the safety support includes a base hard rubber layer and an elastic surface rubber layer connected to the base hard rubber layer; the base hard rubber layer is fixed to the middle position of the outer surface of the rim by bolts." The connection between the "base hard rubber layer" and the "elastic surface rubber layer" can only be in two ways: one is a separate connection, which cannot effectively fix the "base hard rubber layer" and the "elastic surface rubber layer"; the other is an integrated connection. Based on the above discussion, the integrated connection of the "base hard rubber layer" and the "elastic surface rubber layer" cannot achieve the fixation of the "safety support" and the "rim" by bolts. Therefore, the document has a significant defect.

[0018] Therefore, it is evident that the aforementioned document has significant flaws, and the technical solution described in the document cannot be implemented. Utility Model Content

[0019] This utility model addresses the aforementioned deficiencies by providing a novel explosion-proof tire and tire leak-proof wheel without altering some common technologies of existing wheels (or hubs). It incorporates solutions from Chinese patent documents, including Utility Model Patent Publication (Authorization Announcement No.) CN209274284U ("Explosion-proof Tire Hub, Explosion-proof Tire and Mobile Tool"), Utility Model Patent Publication (Authorization Announcement No.) CN201158279Y ("Explosion-proof Tire Rim"), and Utility Model Patent Publication (Authorization Announcement No.) CN207594654U ("A Safe Explosion-proof Automobile Wheel"). This solution addresses the problem that when a car tire explodes or leaks air, it immediately loses its support, causing the vehicle to lose balance.

[0020] The technical solution adopted by this utility model is as follows: A novel explosion-proof and tire-leakage-proof wheel includes a wheel body, a secondary rim, secondary spokes, and an elastomer. The secondary rim and secondary spokes are located in the middle position inside the outer end of the wheel body. The secondary rim and the wheel body are fixedly connected by the secondary spokes. Preferably, the wheel body, secondary rim, and secondary spokes are integrated and coaxially arranged. An elastomer is provided at the outer end of the secondary rim. The cross-section of the outer end of the elastomer is arc-shaped. The elastomer is preferably a solid tire. Tires are installed inside both sides of the outer end of the wheel body. The secondary rim, secondary spokes, and elastomer are located in the internal space between the tire and the outer end of the wheel body. The height and width of the secondary rim and elastomer have a certain gap with the tire. The outer diameter of the tire is larger than the outer diameter of the elastomer. The outer diameter of the elastomer is larger than the outer diameter of the secondary rim. The outer diameter of the secondary rim is larger than or equal to the outer diameter of the wheel body.

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] 1. When a tire of a moving vehicle suddenly blows out or deflates, the distance between the outer edge of the tire and the ground decreases, while the inner edge of the tire comes into contact with the solid tire on the secondary rim. The solid tire supports the tire, thus solving the problem of the vehicle losing balance and causing a car accident due to the tire immediately losing its support.

[0023] 2. After the solid tire on the secondary rim comes into contact with the tire, the solid tire relies on the friction between itself and the tire to maintain effective contact between the outside of the tire and the ground, and the tire can still maintain the normal driving of the vehicle.

[0024] 3. The advantages of solid tires on the secondary rim are wear resistance and puncture resistance.

[0025] 4. The tires can be used with complete peace of mind. You don't need to worry about tire blowouts or tire leaks causing vehicle imbalance, reducing the occurrence of accidents caused by tire problems.

[0026] 5. It greatly reduces the tire replacement cycle. As long as the tires are not damaged, they can be used normally, which reduces the cost of vehicle use and reduces waste of resources. Attached Figure Description

[0029] The specific embodiments of this utility model are described below with reference to the accompanying drawings. It should be noted that, generally speaking, the wheel body includes a hub, spokes, and rim. The rim is used to mount and support the tire. The hub and rim are fixedly connected by the spokes. Due to the integration of the hub, spokes, and rim, many people consider the wheel and hub to be the same object. For example, the term "hub" in the Chinese patent document "Explosion-proof Tire Hub, Explosion-proof Tire and Mobile Tool" is the same as the commonly used term "wheel". For ease of explanation, the term "wheel" in this document and the commonly used term "hub" refer to the same object. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used in this specification of this utility model is for the purpose of describing specific embodiments only and is not intended to limit this utility model.

[0030] like Figure 1 As shown, a novel run-flat and leak-proof tire wheel comprises a wheel body 1, a secondary rim 2, secondary spokes 3, and an elastomer 4. Without altering some common technologies of the existing wheel body 1, the secondary rim 2 and secondary spokes 3 are positioned at the middle of the outer end of the wheel body 1. The secondary rim 2 is fixedly connected to the wheel body 1 via the secondary spokes 3. Preferably, the wheel body 1, secondary rim 2, and secondary spokes 3 are integrated, and are coaxial with their centers on the same center line. An elastomer 4 is provided at the outer end of the secondary rim 2. The outer circumference of the elastomer 4 is circular, and the cross-section of the outer end of the elastomer 4 is arc-shaped, with a maximum... To ensure that in the event of a tire blowout or air leak, the outer surface of the elastomer 4 and the inner surface of the tire 5 maintain a near-perfect fit, this prevents slippage due to reduced friction between the elastomer 4 and the tire 5 during driving. The elastomer 4 is preferably a solid tire, which is wear-resistant and puncture-resistant. The solid tire ensures that in the event of a tire blowout or air leak, it reduces the overall distance between the wheel body 1 and the ground, and supports effective contact between the tire 5 and the ground, achieving a smooth transition between the tire 5 and the solid tire, maintaining vehicle balance, and ensuring normal and safe driving.

[0031] Tires 5 are installed on both sides of the outer end of the wheel body 1. The secondary rim 2, secondary spokes 3, and elastomer 4 are located in the internal space between the tire 5 and the outer end of the wheel body 1. The height and width of the secondary rim 2 and elastomer 4 are separated from the tire 5 by a certain gap. The gap between the elastomer 4 and the tire 5 is such that it does not hinder the normal installation of the tire 5 and the wheel body 1. The outer diameter of the tire 5 is larger than the outer diameter of the elastomer 4. The outer diameter of the elastomer 4 is larger than the outer diameter of the secondary rim 2. The outer diameter of the secondary rim 2 is larger than or equal to the outer diameter of the wheel body 1. The area of ​​the secondary rim 2, secondary spokes 3, and elastomer 4 is designed to minimize their occupation of the internal space between the tire 5 and the wheel body 1 while ensuring reasonable tire pressure and air storage capacity of the tire 5.

[0032] The specific working process of this utility model embodiment is as follows: Under normal circumstances, the wheel body 1 and the tire 5 are supported by a certain air pressure, and the outside of the tire 5 is in contact with the ground. The internal space between the tire 5 and the outer end of the wheel body 1 is provided with a secondary rim 2, secondary spokes 3, and an elastic body 4. The elastic body 4 provided on the secondary rim 2 is preferably a solid tire (Note: the following description of the elastic body 4 will refer to a solid tire). A certain gap is provided between the outer circumference of the solid tire and the inner circumference of the tire 5. Since the outer diameter of the tire 5 is larger than the outer diameter of the solid tire, the outer diameter of the solid tire is larger than the outer diameter of the secondary rim 2, and the outer diameter of the secondary rim 2 is greater than or equal to the outer diameter of the wheel body 1, the solid tire reduces the vehicle's... The distance between the wheel body 1 and the ground; the vehicle travels normally with the support of the tire 5. When the tire 5 blows out or leaks air, the vehicle's weight causes the inner end of the tire 5 to quickly contact the outer end of the solid tire. The solid tire quickly supports the tire 5 and makes contact with the ground. The contact between the solid tire and the tire 5 achieves a smooth transition in supporting the vehicle. Furthermore, the contact surfaces of the outer end of the solid tire and the inner end of the tire 5 are basically in contact, preventing the friction between the solid tire and the tire 5 from decreasing and slipping during vehicle operation after the tire 5 blows out or leaks air. This maintains the basic balance of the vehicle and ensures that the vehicle can continue to travel normally and safely.

[0033] Finally, it should be noted that the above description is only one specific embodiment of this utility model, and the embodiment is only used to illustrate the technical solution of this utility model, and not to limit other forms; although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent substitutions for some or all of the technical features, and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of this utility model; the protection scope of this utility model is not limited to this, and any equivalent transformations and modifications based on the technical solutions of this utility model shall fall within the protection scope of the technical solutions of this utility model.
