Automatic color-change tire for road situations

Abstract

The invention discloses an automatic color-change tire for road situations. The tire comprises a tire body, an electrochromism part, thermochromism modified tire rubber and a photochromic layer, wherein the tire body consists of a tire crown, tire shoulder pad rubber, side tire rubber and tire ring rubber through integral vulcanization; the thermochromism modified tire rubber is arranged on the outer layer of the tire crown; pattern blocks and troughs which are staggered mutually are arranged on the outer layer of the thermochromism modified tire rubber; the electrochromism part is embedded into the tire shoulder pad rubber; convex anti-friction lines are arranged on the outer wall of the side tire rubber; and the photochromic layer is arranged inside the anti-friction lines. The tire crown is large in grounding area and good in ground grasping property, so that the tire body is not easily punctured and is good in friction resistance, and reversible color change can be achieved along with temperature change; and due to adoption of the electrochromism part of the tire shoulder pad rubber, the color of the tire is automatically changed under different lighting intensities, together with the photochromic layer of the anti-friction lines, the color of the tire is relatively brightened under different light intensities, the tire recognition degree is increased, and traffic accidentscan be reduced.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to an automatic color-changing tire under road conditions. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Tires are usually installed on the rim of the car, which can support the entire body, buffer the impact of the outside world, realize contact with the road surface and ensure the normal running of the vehicle. The tires are affected by high and low temperature when driving, and the wear resistance and flex resistance of the tires need to be ensured. Conventional tires are black. Discrimination ability is different. [0003] The existing color-changing tires are as follows: adding red and black inner layer patterns to the inner layer of the tread. When the tire is worn for a period of time, the inner red tread is exposed to remind people of the degree of tire wear. A function to ...
