Description

Technical Field

[0001] This utility model relates to the field of mountain bike technology, specifically to an explosion-proof inner liner for a mountain bike tubeless tire. Background Technology

[0002] Mountain bikes are professional off-road riding products, typically used on rocky, muddy, unpaved surfaces, as well as on specially designed off-road riding park tracks. They place extremely high demands on the vehicle's passability, stability when cornering, and grip. Many mountain bike riders choose to lower the tire pressure to obtain better grip and shock absorption performance. To meet market needs, there is a need for a run-flat liner for tubeless tires on mountain bikes.

[0003] Existing run-flat liner materials cannot effectively conform to the inner wall of the tire, nor can they effectively support the tire sidewall. They have poor adaptability to tire sidewall deformation, especially under low tire pressure, where they cannot provide effective support, which may lead to riding instability and reduced cornering performance. In addition, the existing run-flat liner materials have insufficient impact resistance, which reduces the impact resistance and comfort of mountain bike tubeless tires, increases vibration during riding, reduces the overall tire protection performance, and cannot reduce the risk of tire damage. Therefore, they are not suitable for use in rugged mountain and off-road environments. Utility Model Content

[0004] The purpose of this invention is to provide an explosion-proof inner liner for tubeless tires of mountain bikes, in order to solve the problem mentioned in the background art that the explosion-proof inner liner does not have high enough impact resistance when used.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a liner for a mountain bike tubeless tire explosion-proof liner, comprising a liner body, the surface of which is provided with grooves, a tubeless tire is provided on one side of the liner body, the liner body is disposed inside the tubeless tire, and a tubeless rim is installed on the surface at the bottom of the tubeless tire.

[0006] Preferably, the inner liner body is made of highly elastic EVA material, which prevents the inner liner body from absorbing the sealant of the vacuum tire.

[0007] Preferably, the surface of the vacuum wheel ring has a groove, the surface of the bottom of the inner liner body is in contact with the surface of the groove, a vacuum nozzle is installed on the surface of the bottom of the vacuum wheel ring, one end of the vacuum nozzle passes through the vacuum wheel ring and extends into the interior of the groove, and the surface of the vacuum nozzle is in contact with the inner wall of the groove.

[0008] Preferably, the function of the slots is to allow air to pass through the interior of the vacuum tire normally without being blocked, and the slots allow the inner liner body to be used with only ordinary vacuum valves, while also effectively reducing weight.

[0009] Preferably, the inner wall of the vacuum wheel ring is equipped with a sealing gasket to make the inner liner body and the vacuum wheel ring fit more closely. The surface of the sealing gasket is in contact with the surface at the bottom of the inner liner body, and the sealing gasket is made of rubber.

[0010] Preferably, the inner liner body has a cross-section that is relatively flat on both sides and protrudes at the bottom. The inner liner body is in contact with the inner wall of the vacuum tire and the surface of the vacuum wheel rim, respectively. The surface at the bottom of the inner liner body is in contact with the surface of the groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the explosion-proof inner liner of the mountain bike tubeless tire makes the structure of the explosion-proof inner liner simpler, easier to manufacture, and more convenient to use, and has a wide range of applicability. It can significantly improve the impact resistance and comfort of the mountain bike tubeless tire, reduce vibration during riding, improve the overall tire protection performance, effectively reduce the risk of tire damage, and ensure a safe and smooth riding experience. It is especially suitable for use in rugged mountain and wilderness environments.

[0012] By incorporating an inner liner body, sealing gaskets, and grooves, the sealing gaskets further enhance the tighter contact between the inner liner body and the tubeless tire rim. After installation, the surface of the inner liner body adheres to the inner wall of the tubeless tire. This contact with the lower half of the tubeless tire provides support to the sidewall, reducing tire sidewall deformation. Under low tire pressure riding conditions, the inner liner body provides additional support to the inner wall of the tubeless tire, thereby improving cornering performance and riding stability. It also effectively prevents damage to the tubeless tire rim when hitting sharp rocks, steps, or other obstacles, ensuring the integrity and safety of the tubeless tire rim. When a tubeless tire punctures and leaks air, the inner liner can still be used as an emergency tire, allowing continued riding without damaging the rim. Its thicker thickness ensures continued riding even after a tire puncture. When the tubeless rim is impacted, the inner liner acts as a damping buffer, achieving high impact resistance. This makes the structure simpler, easier to manufacture, and more convenient to use, with wide applicability. It significantly improves the impact resistance and comfort of tubeless tires for mountain bikes, reduces vibration during riding, enhances overall tire protection, effectively reduces the risk of tire damage, and ensures a safe and smooth ride. It is particularly suitable for use in rugged mountain and off-road environments. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. In addition, the terms "first", "second", "third", "upper", "lower", "left", "right", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. 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 scope of protection of the present utility model.

[0019] This utility model provides a structure for an explosion-proof inner liner for a mountain bike tubeless tire, as follows: Figures 1 to 4As shown, the device includes an inner liner body 1, the surface of which has a groove 104. The inner liner body 1 is made of high-elasticity EVA material, which prevents it from absorbing the self-sealing fluid of the vacuum tire 101. A vacuum tire 101 is mounted on one side of the inner liner body 1, and the inner liner body 1 is located inside the vacuum tire 101. A vacuum wheel ring 102 is mounted on the bottom surface of the vacuum tire 101, and a groove 103 is formed on the surface of the vacuum wheel ring 102. The bottom surface of the inner liner body 1 contacts the surface of the groove 103. A vacuum nozzle 106 is mounted on the bottom surface of the vacuum wheel ring 102, one end of which penetrates the vacuum wheel ring 102 and extends into the groove 104. The surface of the vacuum nozzle 106... The groove 104 contacts the inner wall of the tube tire 101. The function of the groove 104 is to allow air to pass through the tube tire 101 normally without being blocked. The opening of the groove 104 allows the inner liner body 1 to be used with only a regular vacuum nozzle 106. On the other hand, it can also effectively reduce weight. The inner wall of the tube tire 102 is equipped with a sealing gasket 105 to make the inner liner body 1 and the tube tire 102 fit better. The surface of the sealing gasket 105 is in contact with the surface of the bottom position of the inner liner body 1. The sealing gasket 105 is made of rubber. The shape of the inner liner body 1 is that the cross-section is flat on both sides and protrudes at the bottom. The inner liner body 1 is in contact with the inner wall of the tube tire 101 and the surface of the tube tire 102. The surface of the bottom position of the inner liner body 1 is in contact with the surface of the groove 103.

[0020] During installation, the user inserts the inner liner body 1 into the tubeless tire 101, just like a traditional inner tube, ensuring proper installation. This allows the inner liner body 1 to contact the surface of the sealing gasket 105. The sealing gasket 105 further strengthens the contact between the inner liner body 1 and the tubeless rim 102. After installation, the surface of the inner liner body 1 adheres to the inner wall of the tubeless tire 101. By adhering to the lower half of the tubeless tire 101, it provides support to the sidewall of the tubeless tire 101, reducing the deformation of the tire sidewall. Under low tire pressure riding conditions, the inner liner body 1 provides additional support to the inner wall of the tubeless tire 101, thereby improving cornering performance and riding stability. It also effectively prevents damage to the tubeless rim 102 when the tubeless tire 101 hits sharp rocks, steps, or other obstacles, ensuring the integrity and safety of the tubeless rim 102. When the tubeless tire 101 is damaged and leaks air, the inner liner body 1 can still be used as an emergency tire, allowing you to continue riding without damaging the rim. The thicker thickness allows you to continue riding for a long distance even after a tire rupture. When the tubeless rim 102 is impacted, the inner liner body 1 can act as a damping buffer to achieve the high impact resistance of the explosion-proof inner liner.

[0021] Working principle: In use, first place the inner liner body 1 in the designated position. The user inserts the inner liner body 1 into the tubeless tire 101, just like a traditional inner tube, ensuring proper installation. This allows the inner liner body 1 to contact the surface of the sealing gasket 105. The sealing gasket 105 further strengthens the contact between the inner liner body 1 and the tubeless rim 102. After installation, the surface of the inner liner body 1 adheres to the inner wall of the tubeless tire 101. By adhering to the lower half of the tubeless tire 101, it provides support to the sidewall of the tubeless tire 101, reducing the deformation of the tire sidewall. Under low tire pressure riding conditions, the inner liner body 1 provides additional support to the inner wall of the tubeless tire 101, thereby improving cornering performance and riding stability. It also effectively prevents damage to the tubeless rim 102 when the tubeless tire 101 hits sharp rocks, steps, or other obstacles, ensuring the integrity and safety of the tubeless rim 102. When the tubeless tire 101 is damaged and leaks air, the inner liner body 1 can still be used as an emergency tire, allowing you to continue riding without damaging the rim. The thicker thickness allows you to continue riding for a long distance even after a tire rupture. When the tubeless rim 102 is impacted, the inner liner body 1 can act as a damping buffer. Because the inner liner body 1 is made of high-elasticity EVA closed-cell material, it does not absorb the sealant of the tubeless tire 101 during use. When the inner liner body 1 is installed inside the tubeless tire 101, it supports the soft sidewalls of the tubeless tire 101 without completely filling it. This prevents the tubeless tire 101 from being unable to adjust tire pressure flexibly according to terrain, failing to provide the same excellent shock absorption and deformation recovery capabilities as when filled with air, and avoiding a significant increase in weight. This achieves the high impact resistance of the explosion-proof inner liner, making its structure simpler, easier to manufacture, and more convenient to use. It has wide applicability and can significantly improve the impact resistance and comfort of mountain bike tubeless tires, reduce vibration during riding, and enhance the overall tire protection performance. It can effectively reduce the risk of tire damage and ensure a safe and smooth riding experience. It is particularly suitable for use in rugged mountain and off-road environments, thus completing the function of the explosion-proof inner liner.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
