In order to solve the problem of short-distance transportation in urban areas, shared bicycles have become an important means of transportation in urban areas. The tire is the only part of a bicycle that contacts the road surface. The maneuverability of the bicycle is realized by transmitting force to the ground through the tire. Therefore, the performance of the tire directly affects the performance of the bicycle. In order to prevent the internal gas from leaking and causing insufficient tire pressure, a sealant is often coated inside the tire body, and after curing, a gas-tight layer is formed to improve the airtightness.

DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the specification of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0024] Embodiment:
[0025] Please refer to the drawings of the present application Figure 1 - the drawings of the present application Figure 3 The embodiment of the present application provides a low flat bicycle tire, which comprises a flat bicycle tire 1, the inside of the flat bicycle tire 1 comprises a wear-resistant ring 8, the inside of the wear-resistant ring 8 is fixedly connected with a supporting layer 13, the inside of the supporting layer 13 is fixedly connected with a micro capsule 12, the outer wall of the micro capsule 12 is fixedly connected to the inner wall of the wear-resistant ring 8, the inside of the supporting layer 13 is fixedly connected with a puncture-proof layer 11, the inside of the puncture-proof layer 11 is fixedly connected with a micro capsule 12, the outer wall of the puncture-proof layer 11 is fixedly connected to the other side of the outer wall, and the inside of the flat bicycle tire 1 is slidably connected with a connecting assembly.
[0026] Specifically, when a sharp object punctures the tire, it first penetrates the puncture-resistant layer and damages the internal microcapsules 12, which release the repair agent composed of epoxy resin and curing agent upon rupture. These substances react and rapidly solidify in the damaged area, filling the cracks and preventing air leakage, significantly extending the service life of the tire and reducing the frequency of tire replacement due to minor damage, improving safety and reliability during cycling. The puncture-resistant layer design effectively blocks sharp objects, protecting the inner tire 18 from direct damage. Even if the puncture-resistant layer is breached, the inner self-repairing system immediately activates, providing double protection. This multi-layer protection structure greatly improves the durability and safety of the tire. When the sharp object further penetrates the inner tire 18, the support layer 13 in the inner tire 18 triggers the automatic inflation of multiple micro-air bags 14 connected to it. These air bags quickly fill the damaged area, preventing gas leakage and maintaining the stability of the tire's air pressure. The automatic inflation air bag design not only provides immediate repair function, but also ensures the stability and safety of the tire during cycling.
[0027] Please refer to the attached Figure 1 - attached Figure 3 , the connecting assembly includes a fixed ring 2, the outer wall of the fixed ring 2 is slidingly connected inside the flat tire 1, the inner part of the fixed ring 2 is fixedly connected with a rubber pad 19, the inner part of the support layer 13 is fixedly connected with a tire lip core 16, the outer wall of the support layer 13 is fixedly connected with a sealing pad 17, the inner part of the support layer 13 is fixedly connected with a micro-air bag 14, the outer wall of the sealing pad 17 and the inner wall of the fixed ring 2 are in close contact, the inner part of the wear-resistant ring 8 is fixedly connected with an elastic body 15, the inner part of the elastic body 15 is fixedly connected with an inner tire 18, the upper surface of the flat tire 1 is fixedly connected with an anti-skid strip 9, the inner part of the anti-skid strip 9 is fixedly connected with multiple anti-skid blocks 10.
[0028] Specifically, the sealing ring connected to the outer wall of the elastomer 15 tightly fits the inner wall of the fixed ring 2, significantly improving the sealing performance of the tire. This design effectively prevents gas leakage and ensures the stability of the tire's air pressure during long-term use, thereby improving the safety and comfort of cycling. When the tire is in use, the tire lip core 16 inside the support layer 13 and the rubber pad 19 inside the fixed ring 2 will be squeezed. This design, through the joint action of the tire lip core 16 and the fixed ring 2, absorbs the impact force on the tire during cycling, reducing the degree of vibration transmitted to the bicycle body and the rider, improving the stability and comfort of cycling. The outermost layer of the tire is made of high-strength wear-resistant rubber material, greatly improving the wear resistance of the tire. This design not only prolongs the service life of the tire, but also reduces the need for frequent tire replacement, reducing maintenance costs. The middle layer is a puncture-proof and shock-absorbing layer made of high-elasticity rubber or polymer foam material. This high-elasticity material can effectively absorb the vibration caused by uneven road surfaces, providing excellent shock-absorbing effect, thereby improving the comfort of cycling, especially in complex road conditions. The inner layer is made of rubber material with good support performance, serving as the support layer 13. This design enhances the overall structural stability of the tire, ensuring that the tire remains stable under high load and high-speed cycling conditions, thereby ensuring the safety and reliability of cycling.
[0029] Please refer to the attached Figure 4 - attached Figure 5 The fixed ring 2 is internally fixedly connected to a plurality of connecting blocks 3, the connecting blocks 3 are internally threadedly connected to a plurality of support rods 4, the support rods 4 are fixedly connected to bearings 5 on their outer walls, the bearings 5 are rotatably connected to support discs 6 on their outer walls, the support discs 6 are slidably connected to the outer walls of the support rods 4, the support discs 6 are internally threadedly connected to bolts 7, and the bolts 7 are externally threaded into the bearings 5.
[0030] Specifically, when the device is needed, simply insert the outer wall of the flat tire 1 into the fixed ring 2. This design makes the installation process simple and fast, without the need for complex tools and operation steps, significantly improving the convenience and user experience of the device. Connect the bearings 5 and support discs 6 and fix them by rotating the bolts 7, which ensures the stability and safety of the tire in use. The multiple support rods 4 connected by the connecting blocks 3 inside the fixed ring 2 provide firm support for the tire, preventing deformation of the tire under high load or high-speed cycling, improving the stability and durability of the overall structure. The cooperation of the low-flat-ratio bicycle tire and the air leakage prevention component further enhances the sealing performance of the tire, effectively preventing gas leakage. This design not only ensures the stability of the tire's air pressure and reduces the need for frequent tire inflation, but also improves the safety and reliability of cycling.
