Description

Technical Field

[0001] This utility model belongs to the field of automotive tire technology, specifically a self-healing puncture-resistant tire that requires no repair. Background Technology

[0002] Self-sealing tires are a type of tire that achieves repair-free functionality by integrating a highly elastic and highly sealing self-sealing coating on the inner side of the tread or in the tire body structure. When a sharp foreign object punctures the tire, the polymer material of the self-sealing layer deforms due to external pressure, immediately wrapping the foreign object to form a preliminary seal and prevent rapid loss of tire pressure. After the foreign object is removed, the material quickly fills the puncture hole under the combined action of its own elastic recovery force and the internal air pressure of the tire, completing the self-repair through molecular chain adhesion or physical closure.

[0003] However, self-healing coatings are fluid. While they can fill punctures in tires and repair them, the tire as a whole is still not intact. When the tire goes over potholes, the impact increases the pressure on the tire, causing the puncture to suddenly experience increased pressure and resulting in air leakage from the repaired puncture.

[0004] Therefore, a self-healing, puncture-free tire is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a self-healing, puncture-free tire.

[0006] The technical solution adopted by this utility model to solve its technical problem is a self-healing puncture-free tire, including a tire body, grooves are opened on the outer surface of the tire body, a self-healing component is provided inside the tire body, and a support component is provided on the inner wall side of the tire body. The support assembly includes a reinforcing ring fixedly installed on the bottom side of the inner wall of the tire body and a support ring fixedly installed on the top side of the inner wall of the tire body. The reinforcing ring has a reinforcing steel wire ring inside, and a support rod is fixedly installed on the top of the reinforcing steel wire ring. The top of the support rod is fixedly installed on the bottom of the support ring.

[0007] Preferably, multiple support rods are provided, and multiple support rings are arranged in a circular array between the reinforcing ring and the support ring.

[0008] Preferably, the support rod has a reinforcing core inside, and the reinforcing core is made of metal.

[0009] Preferably, the self-healing component includes a groove formed at the bottom of the inner wall of the tire body, the outside of the groove is coated with a self-healing coating, and sound-absorbing cotton is installed on the outside of the self-healing coating.

[0010] Preferably, three sound-absorbing cotton materials are provided, and the three sound-absorbing cotton materials are arranged in a circumferential array at the bottom of the inner wall of the tire body.

[0011] Furthermore, the sound-absorbing cotton is configured in three sections, which form a circle that covers the inside of the tire body, providing full coverage of the tire body and the self-healing coating.

[0012] Preferably, a limiting rod is installed on the top of the sound-absorbing cotton, and the two ends of the limiting rod are fixedly installed on the outer surface of the support rod.

[0013] Furthermore, multiple limit rods are provided, and each limit rod is installed in a corresponding manner with a support rod. The limit rods are installed laterally inside the tire body.

[0014] The beneficial effects of this utility model are: This invention involves installing reinforcing rings and reinforcing steel wire rings on both sides of the bottom inner wall of the tire body, thereby increasing the support force on the sides of the tire body and distributing the pressure on the tire tread. The support rod can further support the reinforcing ring, increasing the support force of the reinforcing ring, and thus increasing the overall support force of the tire body. This can effectively prevent the tire body from being deformed by impacts and causing air leakage.

[0015] 2. In this utility model, a self-healing coating is applied to the inner wall of the tire body, and a sound-absorbing cotton is adhered and covered on top of the self-healing coating. The top of the sound-absorbing cotton is held in place by a limiting rod to prevent the self-healing coating from flowing, so that the self-healing coating can flow to the puncture hole and fill and seal the puncture hole, thereby achieving the effect of self-healing the puncture hole of the tire body.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0019] Please see Figures 1-4 As shown, a self-healing puncture-resistant tire includes a tire body 1, with grooves 11 on the outer surface of the tire body 1, a self-healing component 2 inside the tire body 1, and a support component 3 on the inner side wall of the tire body 1.

[0020] Through the above technical solution, grooves 11 are opened on the outer surface of the tire body 1 to increase the friction of the tire tread and reduce the noise of the tire during driving. The self-healing component 2 is set at the bottom of the inner wall of the tire body 1 to repair the tire puncture. The support component 3 can support the tire body 1 to prevent the tire body 1 from leaking air due to tire compression after the tire body 1 is punctured and self-healed.

[0021] First, considering how to support a tire after a puncture repair, refer to... Figure 2 and Figure 3 The specific structure of the support component 3 is disclosed. The support component 3 includes a reinforcing ring 301 fixedly installed on the bottom side of the inner wall of the tire body 1 and a support ring 302 fixedly installed on the top side of the inner wall of the tire body 1. A reinforcing steel wire ring 303 is provided inside the reinforcing ring 301. A support rod 304 is fixedly installed on the top of the reinforcing steel wire ring 303. The top of the support rod 304 is fixedly installed on the bottom of the support ring 302.

[0022] Multiple support rods 304 are provided, and multiple support rings 302 are arranged in a circular array between the reinforcing ring 301 and the support ring 302.

[0023] The support rod 304 has a reinforcing core 4 inside, which is made of metal.

[0024] Through the above technical solution, reinforcing rings 301 are installed on both sides of the bottom inner wall of the tire body 1, and reinforcing steel wire rings 303 are installed inside the reinforcing rings 301 to increase the support force on both sides of the tire body 1. The support ring 302 is fixedly installed on the top of the inner wall side of the tire body 1, and the top of the support rod 304 is fixedly installed on the bottom of the support ring 302, while the bottom of the support rod 304 is fixedly installed on the top of the reinforcing ring 301. Multiple support rods 304 are then installed in a circumferential array on the support rods 304 and the reinforcing ring 301. In the middle, a steel wire reinforcing core 4 is added inside each support rod 304, so that the support rod 304 can increase the supporting force on the reinforcing ring 301. When the tire body 1 is punctured, the self-healing component 2 repairs the tire body 1. When the puncture hole is hit by a pit, the problem of air leakage will occur. The reinforcing ring 301, the reinforcing steel wire ring 303 and the support rod 304 can provide support to both sides of the tire body 1, distribute the pressure on the tire body 1 tread, and reduce the situation of air leakage after the tire body 1 self-repairs the puncture hole.

[0025] Secondly, considering the question of how to apply the self-healing coating 202 to the inner wall of the tire body 1, refer to... Figure 2 and Figure 4 The specific structure of the self-healing component 2 is disclosed. The self-healing component 2 includes a groove 201 opened at the bottom of the inner wall of the tire body 1, a self-healing coating 202 coated on the outside of the groove 201, and a sound-absorbing cotton 203 installed on the outside of the self-healing coating 202.

[0026] There are three sound-absorbing cotton 203s, which are arranged in a circular array at the bottom of the inner wall of the tire body 1.

[0027] Through the above technical solution, multiple circumferentially distributed grooves 201 are opened on the inner wall of the tire body 1. After the self-healing coating 202 is applied to the inner wall of the tire body 1, the self-healing coating 202 will fill the inside of the grooves 201, making the self-healing coating 202 more firmly adhered to the inner wall of the tire body 1. When the tire body 1 is installed in the car and is driven, the heat of the tire body 1 will cause the self-healing coating 202 to flow, causing the tire dynamic balance to be unbalanced. Covering the outside of the self-healing coating 202 with sound-absorbing cotton 203 allows the self-healing coating 202 to adhere to the sound-absorbing cotton 203, and the sound-absorbing cotton 203 can limit the self-healing coating 202 to prevent it from flowing, thus achieving the effect of limiting the application of the self-healing coating 202 into the inside of the tire body 1, so that the self-healing coating 202 can repair the punctures of the tire body 1.

[0028] It should be noted that the self-healing coating 202 is usually based on a high-elasticity, high-adhesion polymer material, preferably butyl rubber or thermoplastic elastomers. When a sharp foreign object punctures the tire body 1, the self-healing coating 202 deforms under external pressure. Due to its own elasticity and adhesion, the base material will immediately wrap the foreign object to form a preliminary seal, preventing the tire pressure from leaking out quickly. After the foreign object is removed, the self-healing coating 202, driven by the air pressure inside the tire body 1 and the self-adhesion of the material molecules, quickly fills the puncture hole formed by the puncture. The puncture hole is closed through the re-crosslinking of molecular chains or physical adhesion.

[0029] Finally, considering the issue that the sound-absorbing cotton 203 might cause the self-healing coating 202 to shift, please refer to... Figure 4 The top of the sound-absorbing cotton 203 is equipped with a limiting rod 5, and the two ends of the limiting rod 5 are fixedly installed on the outer surface of the support rod 304.

[0030] Multiple support rods 304 arranged in a circular array are provided on both sides of the inner wall of the tire body 1. An upper limit rod 5 is installed in the middle of the support rods 304 so that the upper limit rod 5 is adapted to the thickness of the sound-absorbing cotton 203. The upper limit rod 5 abuts against the top of the sound-absorbing cotton 203, which can limit and squeeze the sound-absorbing cotton 203 into the interior of the tire body 1, thereby limiting and fixing the self-healing coating 202 and preventing the self-healing coating 202 from shifting from the sound-absorbing cotton 203.

[0031] In summary, the working principle of this utility model is as follows: When a sharp object punctures the tire body 1, a self-healing coating 202 is applied to and covers the inner wall of the tire body 1. A sound-absorbing cotton 203 is adhered and covered on the top of the self-healing coating 202. The top of the sound-absorbing cotton 203 is held in place by a limiting rod 5 to prevent the self-healing coating 202 from flowing. This allows the self-healing coating 202 to flow towards the puncture site and fill and seal the puncture site, thus achieving the effect of self-healing the puncture site of the tire body 1. After a puncture is repaired on a self-sealing tire, the puncture site on the tire body 1 may leak air if it is bumped during driving. By installing the reinforcing ring 301 and the reinforcing steel wire ring 303 on both sides of the bottom inner wall of the tire body 1, the support force on the side of the tire body 1 can be increased, and the pressure on the tire tread can be distributed. The support rod 304 can further support the reinforcing ring 301, increase the support force of the reinforcing ring 301, and thus increase the overall support force of the tire body 1, which can effectively prevent the tire body 1 from leaking air when it is bumped.
