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 . Alternatively, the curved segment 103 is in the shape of a polyline, and the angle formed by connecting endpoints between the multiple line segments is 90°-180°. Alternatively, the extension end 104 is in the shape of a polyline. Al...

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 matching 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 structure constitutes the pattern area or text area of ​​the sidewall. The text area displays text, such as "ABCDEFGH" displayed in a smooth plane.

[0086] The designed raised structure can be in the pattern block area, can also surround the text area, or can 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 new type of sidewall pattern and a tire mold, belonging to the field of tires, the tire includes a carcass, the side of the carcass has a marking area, and a plurality of pattern units are arranged in the marking area; the pattern units protrude from the The carcass is provided, and the pattern unit includes a curved portion, and the curved portion includes a curved section and extension ends arranged at both ends of the curved section. Tire molds are used to make the tires described above. This tire has better visual effect and 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 through a tire mold, and a groove structure is provided on the surface of the tire mold, and a corresponding stripe structure is obtained on the tire surface by vulcanization. Usually the tire vulcanization mold is made of metal, and the surface of the tire mold is often processed relatively smooth, with a high degree of finish. However, the outer surface of the black tire thus obtained is smooth, and the smooth outer surface will reflect light, resulting in a poor visual effect of the appearance of the tire surface. Contents of the invention [0003] The present invention provides a tire with a new type of sidewall pattern, aiming to solve the above-mentioned problems existing in tires with a new...
