Description

Technical Field

[0001] This utility model relates to the field of tire technology, specifically to an emergency support safety tire. Background Technology

[0002] Emergency support tires, also known as run-flat tires or tires designed for punctures or tire leaks, are specially designed tires that allow a vehicle to continue driving for a distance in emergency situations such as tire leaks or blowouts. This ensures vehicle safety and driving stability, giving the driver enough time to drive the vehicle to a safe location for repairs or tire replacement.

[0003] Patent CN222387922U discloses a type of explosion-proof tire, comprising a rim, an outer tire, and a pneumatic tire. The outer tire is disposed on and covers the circumferential sidewall of the rim, and the pneumatic tire is disposed between the outer tire and the rim. The pneumatic tire has a partition plate I arranged circumferentially within it, dividing the inner cavity of the pneumatic tire into two equal-sized airtight chambers. The partition plate I and the pneumatic tire are an integral structure. Each airtight chamber has multiple partition plates II evenly spaced circumferentially distributed around the center of the pneumatic tire. This invention, through its internal partition plates I and II, forms two rows of multiple explosion-proof chambers inside the pneumatic tire. Even if any explosion-proof chamber is punctured by a sharp object, the adjacent explosion-proof chamber can still provide support, thus ensuring that the tire retains its long-distance driving capability even after being punctured.

[0004] The existing technology, such as the patent mentioned above, has two air-tight chambers, which allows the tire to still function even if the other air-tight chamber is intact after being punctured. However, the uneven air pressure on both sides of the tire will cause the vehicle to veer to one side while driving. The vehicle will drift towards the side with lower air pressure, which requires the driver to constantly adjust the steering wheel to maintain straight driving, increasing the difficulty of driving and fatigue, and thus increasing the probability of traffic accidents. Utility Model Content

[0005] The purpose of this invention is to provide an emergency support safety tire to address the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an emergency support safety tire, comprising a tire body with an inner cavity, wherein annular elastic support structures are respectively connected between the outer ring of the tire body and the inner rings on both sides, each elastic support structure comprising a plurality of bent elastic support members arranged in a ring array in the inner cavity, each elastic support member having an air chamber inside the bent structure, and an air hole communicating with the air chamber and the inner cavity on the elastic support member.

[0007] Furthermore, the support member and the tire body are integrally molded structures.

[0008] Furthermore, the support member includes a first connecting portion and a second connecting portion that are parallel to each other. A third connecting portion is fixedly connected between one end of the first connecting portion and one end of the second connecting portion. The other end of the first connecting portion is fixedly connected to the outer ring of the tire body, and the other end of the second connecting portion is fixedly connected to the inner ring of the tire body.

[0009] Furthermore, the bending structure is formed at the connection points between each of the first connecting portion, the second connecting portion and the third connecting portion.

[0010] Furthermore, protruding reinforcing portions are provided at the connection points between the first connecting portion and the outer ring, and at the connection points between the second connecting portion and the inner ring.

[0011] Furthermore, each elastic support structure contains 20-30 elastic support components.

[0012] Furthermore, the two elastic support structures are arranged symmetrically about the centerline of the tire carcass.

[0013] Compared with the prior art, the emergency support safety tire provided by this utility model has two situations when the tire body is punctured by a sharp object and inserted into the tire's air chamber. Some of the support components inside the tire are deformed due to the contact and compression between the tire body and the ground, but each support component has elasticity to resist this deformation. The other part of the support components play a supporting role, keeping the tire in a bulging state. In this way, the tire can continue to support the vehicle in emergency situations such as punctures, improving the safety of the vehicle's continued driving. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] Please see Figure 1-3 This utility model provides an emergency support safety tire, comprising a tire body 1 with an inner cavity 11. Annular elastic support structures are connected between the outer ring 12 and the two inner rings 13 on both sides of the tire body 1. The two elastic support structures are symmetrically arranged about the centerline plane of the tire body 1 (centerline plane: a plane passing through the tire's centerline and perpendicular to the axis). Each elastic support structure includes multiple bent elastic support members 2 arranged in a ring array within the inner cavity 11. Each bent section of the elastic support member 2 has an air chamber 3, and the elastic support member 2 has a connecting air chamber. The chamber 3 is connected to the inner cavity 11 by an air vent 31; specifically, the support member 2 includes a first connecting part 21 and a second connecting part 22 that are parallel to each other. A third connecting part 23 is fixedly connected between one end of the first connecting part 21 and one end of the second connecting part 22. The other end of the first connecting part 21 is fixedly connected to the outer ring 12 of the tire body 1, and the other end of the second connecting part 22 is fixedly connected to the inner ring 13 of the tire body 1. The connection between each first connecting part 21, the second connecting part 22 and the third connecting part 23 forms a bending structure. The number of elastic support members 2 in each elastic support structure is 20-30.

[0019] Working principle: Before driving, the user needs to inflate the tire cavity 11 with sufficient air through the valve on the wheel hub to ensure the tires are fully inflated and stable. Then, the user can drive the car. During normal driving, the tires do not deform significantly due to the sufficient air inside, and the support member 2 does not deform during this process. However, if the tire body 1 is punctured by a sharp object that penetrates its cavity 11, air will leak out. The supports function to prevent deformation caused by the leaking air. Taking one support member 2 as an example, its two ends are integrally connected to the outer ring 12 and inner ring 13 of the tire body 1, providing sufficient stability for the connection. When the outer ring 13 of the support member 2 is located... The outer ring 12 and inner ring 13 are brought closer together (the pressure caused by the contact of part of the tire tread with the ground will cause part of the outer ring 12 and inner ring 13 to come closer together), which will then compress the support member 2. When this part of the area is no longer compressed (the support member 2 will undergo elastic deformation during the compression process, and at this time the support member 2 will have the force to recover the deformation), the force of the support member 2 to recover the deformation can drive the outer ring 12 and inner ring 13 of this area to move away from each other and return to the initial state. This is the case for each support member 2. Even when the air in the tire is about to reach the same level as the air pressure, the tire body 1 can still continue to rotate due to the expansion of each support member 2 so that the car can continue to drive. In an emergency such as a puncture, the tire body 1 can still support the car and continue to rotate so that the car can continue to drive, giving the car enough time to drive to a safe position.

[0020] The air chamber 3 within the support member 2, filled with gas, provides excellent support performance. Furthermore, the air vent 31 on the support member 2 allows communication between the air chamber 3 and the inner cavity 11. The air pressure in the air chamber 3 matches that in the air vent 31. Under heat, the support member 2 will not tear during compression due to excessive gas expansion. In cold winter conditions, the support member 2 will not deform due to gas contraction, thus maintaining its support performance. For example, during one complete tire rotation, the time the support member 2 is compressed is much shorter than the time it is supported. During the compression period, the air chamber 3 within the support member 2 vents gas into the inner cavity 11 of the tire body 1 to prevent tearing. During the support period, the gas in the inner cavity 11 flows back into the air chamber 3 (where the pressure is greater than that in the air chamber 3) to restore its support performance.

[0021] This utility model provides an emergency support safety tire. When the tire body 1 is punctured by a sharp object and inserted into the air chamber 3 of the tire body 1, the support members 2 inside the tire are in two situations. Some of the support members 2 close to the ground will deform due to the contact and compression of the tire body 1 with the ground. However, each support member 2 will have elasticity to resist this deformation. The other part of the support members 2 plays a supporting role, keeping the tire in a bulging state. In this way, the tire can continue to support the vehicle in the emergency situation of a puncture, improving the safety of the vehicle to continue driving.

[0022] Among them, the connection between the first connecting part 21 and the outer ring 12 and the connection between the second connecting part 22 and the inner ring 13 are respectively provided with protruding reinforcing parts 4, so that each support member 2 has higher strength at the connection with the tire body 1.

[0023] Among them, the support component 2 and the tire body 1 are integrally molded structures. The same manufacturing materials can make the deformation, wear and aging of each part of the tire more similar when subjected to pressure, friction and impact.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
