Description

Technical Field

[0001] This utility model relates to the field of butyl inner tube technology, specifically a puncture-resistant reinforced butyl inner tube. Background Technology

[0002] Butyl inner tubes are inner tubes made of butyl rubber, mainly used as auxiliary air-bearing containers inside the tire cavities of automobiles, motorcycles, bicycles, and rickshaws. Due to their excellent performance, butyl inner tubes can provide better shock absorption and protection, and extend the service life of the tires.

[0003] Currently, butyl inner tubes are commonly used in various vehicles. However, vehicles are prone to running over sharp objects while driving on the road, which can easily damage the inner tubes. This requires drivers to stop and repair the tires. The poor puncture resistance of inner tubes can lead to increased repair frequency and reduced tire lifespan. To address these issues, we have developed a puncture-resistant reinforced butyl inner tube. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a puncture-resistant reinforced butyl inner tube.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a puncture-resistant reinforced butyl inner tube, comprising an inner tube body, an anti-puncture mechanism provided on the outer side of the inner tube body, the anti-puncture mechanism comprising an outer protective layer, a buffer layer and an airtight layer, a valve stem fixedly connected to the outer surface of the inner tube body, the outer protective layer comprising a gradient fiber distribution layer, the buffer layer comprising a microporous foam layer, a plurality of identical anti-cutting protrusions fixedly connected to the outer surface of the inner tube body, and the bottom surface of the gradient fiber distribution layer fixedly connected to the upper surface of the microporous foam layer.

[0006] Furthermore, a three-dimensional mesh fiber layer is fixedly connected to the upper surface of the gradient fiber distribution layer, and the material of the three-dimensional mesh fiber layer is polyester fiber.

[0007] Furthermore, a honeycomb-shaped impact-resistant layer is fixedly connected to the upper surface of the three-dimensional mesh fiber layer, and the honeycomb-shaped impact-resistant layer is made of honeycomb core carbon fiber composite material.

[0008] Furthermore, a chopped carbon fiber layer is fixedly connected to the upper surface of the honeycomb impact-resistant layer, a liquid butyl rubber layer is fixedly connected to the upper surface of the chopped carbon fiber layer, and a graphene-reinforced butyl rubber layer is fixedly connected to the upper surface of the liquid butyl rubber layer.

[0009] Furthermore, a sealing base is fixedly connected to the outer surface of the valve stem, and the bottom end of the sealing base is fixedly connected to the outer surface of the inner tube body.

[0010] Furthermore, a silicone butyl blend layer is fixedly connected to the bottom surface of the microporous foam layer, a viscoelastic gel interlayer is fixedly connected to the bottom surface of the silicone butyl blend layer, a foamed butyl adhesive layer is fixedly connected to the bottom surface of the viscoelastic gel interlayer, and the bottom surface of the foamed butyl adhesive layer is fixedly connected to the upper surface of the airtight layer.

[0011] Compared with existing technologies, this puncture-resistant reinforced butyl inner tube has the following beneficial effects:

[0012] This invention, through the coordinated arrangement of a gradient fiber distribution layer, a three-dimensional mesh fiber layer, a honeycomb impact-resistant layer, a chopped carbon fiber layer, and a liquid butyl rubber layer, effectively prevents sharp objects from puncturing the inner tube body, enhancing the applicability of the device. It effectively avoids the problem of vehicles easily running over various sharp objects while driving on the road, which can easily damage the inner tube and require the driver to stop for tire repair. However, the poor puncture resistance of the inner tube can easily lead to increased repair frequency and reduced tire life.

[0013] This invention, through the interaction of a microporous foam layer, a silicone butyl blend layer, and a viscoelastic gel interlayer, can achieve balanced buffering, absorb high-frequency vibrations, and improve the absorption rate of impact energy. Attached Figure Description

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] This embodiment provides a puncture-resistant reinforced butyl inner tube. This device is used for vehicles on uneven roads where the inner tube is easily punctured by sharp objects. It can effectively resist the impact of sharp objects such as gravel and nails.

[0022] See Figure 1 , Figure 2 and Figure 3 A puncture-resistant reinforced butyl inner tube includes an inner tube body 1. An anti-puncture mechanism 2 is provided on the outer side of the inner tube body 1. The anti-puncture mechanism 2 includes an outer protective layer 202, a buffer layer 203, and an airtight layer 204. A valve 215 is fixedly connected to the outer surface of the inner tube body 1. A sealing base 216 is fixedly connected to the outer surface of the valve 215. The bottom end of the sealing base 216 is fixedly connected to the outer surface of the inner tube body 1. Through the sealing base 216, weak points at the joints can be reduced, and the overall structural stability can be improved.

[0023] See Figure 4 The outer protective layer 202 includes a gradient fiber distribution layer 205, and a three-dimensional mesh fiber layer 206 is fixedly connected to the upper surface of the gradient fiber distribution layer 205. The material of the three-dimensional mesh fiber layer 206 is polyester fiber. The three-dimensional mesh fiber layer 206 is made of aramid fiber and ultra-high molecular weight polyethylene mixed and woven into a mesh skeleton, which is embedded in the outer wall of the inner tube to improve impact resistance.

[0024] See Figure 4 and Figure 5 The buffer layer 203 includes a microporous foam layer 214, and a honeycomb-shaped impact-resistant layer 207 is fixedly connected to the upper surface of the three-dimensional mesh fiber layer 206. The honeycomb-shaped impact-resistant layer 207 is made of honeycomb core carbon fiber composite material. The honeycomb-shaped impact-resistant layer 207 has a honeycomb structure molded in the easily punctured area to disperse the impact force using biomimetic mechanics.

[0025] See Figure 1 and Figure 4The outer surface of the inner tube body 1 is fixedly connected with several identical anti-cutting protrusions 201. The upper surface of the honeycomb impact-resistant layer 207 is fixedly connected with a chopped carbon fiber layer 208. The upper surface of the chopped carbon fiber layer 208 is fixedly connected with a liquid butyl rubber layer 209. The upper surface of the liquid butyl rubber layer 209 is fixedly connected with a graphene-reinforced butyl rubber layer 210. The liquid butyl rubber encapsulated in microcapsules automatically fills the hole when punctured, achieving instant repair.

[0026] See Figure 4 and Figure 5 The bottom surface of the gradient fiber distribution layer 205 is fixedly connected to the upper surface of the microporous foam layer 214. The bottom surface of the microporous foam layer 214 is fixedly connected to a silicone butyl blend layer 213. The bottom surface of the silicone butyl blend layer 213 is fixedly connected to a viscoelastic gel interlayer 212. The bottom surface of the viscoelastic gel interlayer 212 is fixedly connected to a foamed butyl rubber layer 211. The bottom surface of the foamed butyl rubber layer 211 is fixedly connected to the upper surface of the airtight layer 204. Silicone rubber and butyl rubber are blended. The high damping characteristics of silicone rubber are used to absorb high-frequency vibrations. Shear thickening gel is embedded between the foam layers. It hardens instantly when impacted, dispersing the stress peak.

[0027] Working principle: When in use, the outer surface of the inner tube body 1 is first fixed with wave-shaped anti-cutting protrusions 201, which can improve the lateral anti-cutting ability. During vehicle operation, the graphene-reinforced butyl rubber layer 210 can improve the tear resistance and thermal conductivity of the inner tube, reduce high-speed friction heat generation, and the chopped carbon fiber layer 208 can enhance the puncture resistance while maintaining lightweight, effectively preventing the inner tube from being punctured by sharp objects. When a sharp object punctures the liquid butyl rubber layer 209, the capsule ruptures and automatically fills the hole, achieving immediate repair.

[0028] When a vehicle travels on uneven roads and the inner tube is impacted, a three-dimensional mesh fiber layer 206 is used to weave aramid fibers and ultra-high molecular weight polyethylene into a mesh skeleton, which is embedded in the outer wall of the inner tube to improve impact resistance. Combined with a foamed butyl rubber layer 211 for energy absorption and cushioning, and a honeycomb structure is molded in the puncture-prone areas to disperse the impact force using biomimetic mechanics, it can effectively prevent the vehicle from easily running over various sharp objects during road travel, thus avoiding damage to the inner tube and requiring the driver to stop and repair the tire. The poor puncture resistance of the inner tube can easily lead to an increase in the number of inner tube repairs, resulting in a reduction in tire life.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
