Title:
TIRE CAPABLE OF AUTOMATICALLY CHANGING COLOR ACCORDING TO ROAD CONDITIONS
Document Type and Number:
WIPO Patent Application WO/2019/041879
Kind Code:
A1
Abstract:
A tire capable of automatically changing color according to road conditions comprises a tire body (4), an electrochromic device (8), a thermochromic modified tread rubber (13), and a photochromic layer (15). The tire body (4) comprises a tire crown (11), a shoulder pad rubber (14), a sidewall rubber (16), and a bead rubber (17), and is integrally formed by means of vulcanization. An outer layer of the tire crown (11) is provided with the thermochromic modified tread rubber (13), and an outer layer of the thermochromic modified tread rubber (13) is provided with alternating patterned blocks (10) and grooves (12). The electrochromic device (8) is embedded in the shoulder pad rubber (14). A protruding kerbing rib (6) is provided on an outer wall of the sidewall rubber (16). The photochromic layer (15) is provided in the kerbing rib (6). The tire crown (11) has a large contact surface area and good traction, such that the tire body (4) is not easily punctured, has strong wear resistance, and achieves a reversible color change as temperature changes. The electrochromic device (8) of the shoulder pad rubber (14) enables a vehicle tire to automatically change color under varying light intensity, and the photochromic layer (15) of the kerbing rib (6) brightens color the of the tire, according to varying light intensity, thereby improving identification of a problematic tire and reducing traffic accidents.
