Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire technology, specifically a tire whose sidewall emits light as the tire rolls. Background Technology
[0002] Tires are made of steel cords, fabric, natural rubber and various polymers. As an important part of automobiles, they are generally made of pure black, a design that is durable and has a certain degree of wear resistance and anti-aging properties.
[0003] Existing tires have limited color options and poor aesthetics. Adding materials to change tire color can easily reduce the tire's mechanical performance. Furthermore, when driving in poor lighting conditions, it can be difficult for bystanders to judge the vehicle's position relative to the driver, increasing the risk of traffic accidents.
[0004] Based on this, a tire that emits light on its sidewall as it rolls is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
[0005] The purpose of this invention is to provide a tire whose sidewall emits light as the tire rolls, in order to solve the problem that tires in the prior art have relatively simple colors and poor aesthetics.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A tire that emits light from its sidewall as it rolls includes a tire body, an anti-skid groove on the outside of the tire body, sidewalls on both sides of the outside of the tire body, and a tire bead on the inside of the sidewall.
[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:
[0009] In one alternative: the sidewall includes a base layer, a light-emitting layer is attached to one side of the base layer, a conductive shielding layer is attached to one side of the light-emitting layer, and a transparent protective layer is attached to one side of the conductive shielding layer.
[0010] In one alternative: the material of the light-emitting layer is a mechanoluminescent substrate, the material of the conductive shielding layer is a graphene conductive coating, and the material of the transparent protective layer is a fluorinated rubber film.
[0011] In one alternative: the tire carcass includes an airtight layer, one side of which is fitted with a puncture-resistant layer, the airtight layer being made of butyl rubber, and the puncture-resistant layer being woven from aramid fibers.
[0012] In one alternative: a fabric layer is attached to one side of the puncture-resistant layer, the fabric layer being composed of 2-8 layers of impregnated polyester fiber cords.
[0013] In one alternative: a belt layer is attached to one side of the fabric layer, the belt layer being composed of a single layer of high-carbon steel wire cord.
[0014] In one alternative: a nylon cover layer is attached to one side of the belt layer, and the nylon cover layer is made of high-strength nylon fabric.
[0015] In one alternative: a tread base rubber layer is bonded to one side of the nylon cover layer, and a tread wear-resistant layer is bonded to one side of the tread base rubber layer. The tread base rubber layer is made of high cis styrene-butadiene rubber, and the tread wear-resistant layer is made of a composite rubber layer of silica and carbon black.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] In this invention, the luminous sidewall area is divided into three parts. When the tire pressure is normal, the sidewall deformation is normal, and the middle area displays a green light source when the tire is rolling. At this time, the tire sidewall is a green luminescent body. When the tire is low on air, the sidewall deformation increases, and the upper and lower areas will also be affected by the large sidewall deformation and light up red. At this time, the entire tire sidewall contains both red and green colors, which warns the vehicle that the tire is low on air and plays a certain role in protecting the vehicle.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0023] In one embodiment, such as Figures 1-3 As shown, a tire with sidewall light that illuminates as the tire rolls includes a tire body 1, an anti-skid groove 4 on the outside of the tire body 1, a sidewall 2 on both sides of the outside of the tire body 1, and a tire bead 3 on the inside of the sidewall 2.
[0024] In this embodiment, the anti-slip groove 4 serves to increase friction. The illuminated sidewall area is divided into three parts. When the tire pressure is normal, the sidewall deformation is normal, and the middle area displays a green light source when the tire is rolling. At this time, the tire sidewall is a green light source. When the tire is low on air, the sidewall deformation increases, and the upper and lower areas will also be affected by the large sidewall deformation and illuminate red lights. At this time, the entire tire sidewall contains both red and green colors, warning the vehicle that the tire is low on air and playing a certain role in protecting the vehicle.
[0025] In one embodiment, such as Figure 1 and Figure 2 As shown, the sidewall 2 includes a base layer 21, a light-emitting layer 22 attached to one side of the base layer 21, a conductive shielding layer 23 attached to one side of the light-emitting layer 22, and a transparent protective layer 24 attached to one side of the conductive shielding layer 23. The light-emitting layer 22 is made of a mechanoluminescent substrate, the conductive shielding layer 23 is made of a graphene conductive coating, and the transparent protective layer 24 is made of a fluorinated rubber film. The light-emitting layer 22 is an example of a mechanoluminescent material, but it is not limited to this. For example, the material is made of silicone-based material, doped with lanthanide ions and transition metal ions to form a piezoelectric material. During tire rolling, light emission is generated by the stretching and compression deformation of the tire sidewall. The light-emitting layer 22 is doped with lanthanide ions or transition metal ions in the silicone matrix, and the piezoelectric effect is triggered by the deformation of the tire sidewall to emit light. The light emission intensity is negatively correlated with the tire pressure. The conductive shielding layer 23 is used to eliminate electrostatic interference and enhance the stability of the light emission signal. The transparent protective layer 24 has a light transmittance of ≥90% and a wear resistance coefficient that is 30% higher than that of ordinary rubber, preventing light attenuation caused by stone scratches.
[0026] In one embodiment, such as Figure 1 and Figure 3As shown, the tire carcass 1 includes an airtight layer 11, with a puncture-resistant layer 12 attached to one side of the airtight layer 11.

A nylon cover layer 15 is attached to the side, the nylon cover layer 15 is made of high-strength nylon cord fabric, a tread base rubber layer 16 is attached to one side of the nylon cover layer 15, a tread wear-resistant layer 17 is attached to one side of the tread base rubber layer 16, the tread base rubber layer 16 is made of high cis styrene-butadiene rubber, and the tread wear-resistant layer 17 is made of a composite rubber layer of silica and carbon black. The airtight layer 11 is bonded to the tire carcass through a co-vulcanization process to form an airtight barrier without a tube structure. This layer needs to withstand temperature fluctuations from -30℃ to 80℃ and resist the penetration of oxidizing gases, with a tire pressure retention rate >99.5% for one month. The puncture-resistant layer 12 has a density of approximately 3000 cords per square meter and is used to protect the tire from punctures by sharp objects such as iron filings and gravel. The ply layer 13 consists of 2-8 layers of impregnated polyester fiber cords, with a single cord tensile strength >15kg and a cord density of 1400 cords / layer, serving as the core layer for load transfer. The belt layer 14 has a diameter of 0.15-0.38mm and a tensile strength of... With a strength >2500MPa, radial stiffness is provided by a circumferential 0° arrangement. The nylon cover layer 15 covers the belt layer 14 with a zero-degree winding process to prevent high-speed displacement of the steel cords. The tread base rubber layer 16 is a transition layer located below the tread pattern with a Shore hardness of 70-75HA to ensure stress transfer between the tread blocks and the belt layer 14. The tread wear-resistant layer 17 has a thickness of 8-12mm and a surface design with mixed transverse and longitudinal patterns. The water drainage rate is ≥1.2L / s, and the noise reduction effect is improved by 3-5dB.

The belt layer 14 has a diameter of 0.15-0.38mm, a tensile strength >2500MPa, and provides radial stiffness with a 0° circumferential arrangement. The nylon cover layer 15 covers the belt layer 14 using a zero-degree winding process to prevent high-speed displacement of the steel cords.

The tread wear-resistant layer 17 is 8-12mm thick, with a mixed transverse and longitudinal pattern on its surface, a water drainage rate ≥1.2L / s, and a noise reduction effect improved by 3-5dB.
