Embodiment 1

[0057] This embodiment provides a tire with a new type of sidewall pattern, see figure 1 -Figure 5, Figure 7-Figure 16 .

[0058] This tire with a new type of sidewall pattern includes a carcass, the side of the carcass has a marking area, and a plurality of pattern units 101 are arranged in the marking area, the pattern units 101 protrude from the carcass, and the pattern units 101 include curved parts 102 , the curved portion 102 includes a curved section 103 and extension ends 104 disposed at both ends of the curved section 103 .

[0059] The curved section 103 is arc-shaped, and the extension end 104 is also arc-shaped, and the radius of curvature of the extension end 104 is smaller than the radius of curvature of the curved section 103. Or, the curved segment 103 is in the shape of a polyline, and the angle formed by the connection of the endpoints between the multiple line segments is 90°-180°. Alternatively, the extension end 104 is in the shape of a polyline. Alte...

Embodiment 2

[0084] This embodiment provides a tire mold 110 for the tire in Embodiment 1, such as Image 6 As shown, the tire mold 110 includes a side plate, and a groove structure 111 adapted to the pattern unit 101 is arranged on the side plate.

[0085] The side portion of the vulcanized tire can be formed with a designed raised structure through the marking area of ​​the mold. The designed raised structures constitute the tread area or lettering area of ​​the sidewall. The text area displays text, for example "ABCDEFGH" displayed in a smooth plane.

[0086]The designed raised structure can be in the pattern block area, can also surround the text area, and can also be on the text area alone. It is preferable to provide the pattern region on the outer side in the tire radial direction. The groove structure 111 of the mold can be engraved using a laser.

Abstract

The invention provides a tire with a novel tire sidewall pattern and a tire mold and belongs to the field of tires. The tire comprises a tire body. The side portion of the tire body is provided with amarking area. Multiple pattern units are arranged in the marking area. The pattern units protrude from the tire body. Each pattern unit comprises a bent portion, wherein the bent portion comprises abent section and extension ends arranged at the two ends of the bent section. The tire mold is used for manufacturing the tire. The tire has a better visual effect and a better mechanical effect.

Description

technical field [0001] The invention relates to the field of tires, in particular to a tire with a novel sidewall pattern and a tire mold. Background technique [0002] There are a large number of patterns, fonts and other marks on the sidewall of the tire. These marks are made by tire mold, and the surface of tire mold is provided with groove structure, obtains corresponding stripe structure on tire surface by vulcanization. Usually the vulcanization mold of the tire is made of metal, and the surface of the tire mold is often processed more smoothly, and the finish is higher. However, the black tire outer surface thus obtained is smooth, and this smooth outer surface will form a reflection effect on light, resulting in poor visual effects of the tire surface appearance. Contents of the invention [0003] The present invention provides a tire with a novel sidewall pattern, aiming at solving the above-mentioned problems existing in the tires with a novel sidewall pattern ...
