Abstract

The invention relates to a tire, which comprises a tire body and a mark arranged on the tire body, wherein the mark comprises a mark table, a mark outline arranged on the mark table, and a plurality of mark bosses and/or mark depressions filled in the mark outline, the mark bosses are in a quadrangular frustum shape or a quadrangular pyramid shape, and the mark depressions are in a quadrangular frustum depression shape or a quadrangular pyramid depression shape. Compared with the prior art, the grid type identification lug boss or the identification concave adopted by the invention is beneficial to increasing the light reflecting surface and the light reflecting direction, the identifiable angle range of the identification is improved, and the identification lug boss or the identification concave interval in the longitudinal and transverse directions also enables dust to be difficult to fill, so that the identification degree in the dust accumulation state is effectively improved, and in addition, the uneven structure of the identification surface enables the dust accumulation thickness to be different, so that the clear contrast between the identification part and the surrounding side wall surface is favorably formed, and the display effect of the identification is more prominent.

Description

Tyre for vehicle

Technical Field

The invention belongs to the technical field of tires, and relates to a tire.

Background

The tire side wall is provided with a plurality of characters (most of the characters are English letters, and Chinese characters are rare) displaying various information, the characters and the tire side wall are made of the same rubber material, the color is consistent, and only because the surfaces of the characters are 0.5-3mm higher than the surface of the tire side wall, people can recognize the characters. Although the main information, such as the trademark, the tire specification, the pattern model, etc., is displayed by characters with relatively large size, it is not easy for a standing person to see clearly the content of the main information characters on the sidewall at a glance. Because the area of the tire side is limited, more information needs to be displayed on the tire, the size of main information characters is very difficult to increase, the characters adopt different colors from the color of the tire side, and the processing technology is complex and difficult to adopt. The method that is more adopted at present is to generate linear or curved continuous saw-tooth projections on the surface of a large-size character or the surface of a tire side around the character, the difference between the character surface and the tire side surface is improved by increasing the light reflecting area of the character surface and changing the light reflecting direction, and then the identification degree of the character is improved.

Disclosure of Invention

The invention aims to provide a tire, which adopts grid-shaped bosses or depressions to replace continuous bulges as tire marks, properly increases the sizes of the bulges, and changes the angles of the bulge surfaces, thereby solving the problem of low identification degree of the tire side marks in a dust-contaminated state.

The purpose of the invention can be realized by the following technical scheme:

the utility model provides a tire, includes the tire body to and locate the sign on the tire body, wherein, the sign includes the sign platform, locates the sign profile on the sign platform, and a plurality of sign boss and/or sign of filling in the sign profile are sunken, the sign boss is four prismatic table forms or four pyramid form, the sign is sunken to be four prismatic table sunken form or four pyramid sunken form.

Preferably, the length and the width of the mark are both larger than 30mm, and the mark is a character or a letter.

Further, the mark boss and/or the mark depression array are filled in the mark outline or are obliquely filled in the mark outline along the direction of the mark outline.

Further, the ratio of the side length to the height of the mark boss is (1-1.5):1, and the ratio of the side length to the depth of the mark recess is (1-1.5): 1.

Furthermore, the side length of the bottom edge of the identification boss is 1-2mm, and the height of the bottom edge of the identification boss is 0.5-1 mm.

Further, when the identification projection is in the shape of a quadrangular frustum pyramid, the ratio of the length of the top edge to the length of the bottom edge is not more than 0.7, and preferably, the length of the top edge is not more than 1 mm.

Furthermore, the length of the top edge of the mark recess is 1-2mm, and the depth is 0.5-1 mm.

Further, when the marking depression is in the shape of a quadrangular frustum depression, the ratio of the length of the bottom side to the length of the top side is not more than 0.7, and preferably, the length of the bottom side is not more than 1 mm.

Furthermore, the mark depressions and the mark bosses are alternately arranged in the mark outline.

Furthermore, the center distance between adjacent mark bosses, between mark depressions or between the mark bosses and the mark depressions is 1.5-2.5 mm.

Further, the identification contour is a continuous boss with the width of 0.5-1mm and the height of 0.5-1 mm.

Further, the mark is 1.5-3mm higher than the tire body.

Compared with the prior art, the invention has the following characteristics:

1) by taking the identification boss as an example, compared with a continuous type bulge, the grid type identification boss adopted by the invention increases a light reflecting surface and a light reflecting direction, thereby making up the influence of the reduction of the light reflecting area caused by the increase of the interval of the identification boss and improving the identifiable angle range of the identification; the same mark recess can also improve the identification degree of the mark by increasing the reflecting surface and the reflecting direction;

2) because the intervals are arranged between the identification bosses in the longitudinal direction and the transverse direction, and the interval length and the height of the identification bosses are increased, the intervals between the identification bosses are not easily filled with dust, and the influence of the dust on the identification degree is reduced;

3) the uneven structure of sign surface for the dust accumulates the difference of thickness, and then makes the surperficial dust colour of sign inhomogeneous, and forms the contrast with the even dust colour of distribution on the side wall surface around the sign, makes the display effect of sign more outstanding.
