Description

Technical Field

[0001] This utility model relates to the field of tire technology, and more specifically, to a tire. Background Technology

[0002] Currently, tires typically feature lettering, patterns, and other decorative designs on their sidewalls to enhance their aesthetics and brand image. These designs are usually the same color as the sidewall, resulting in poor visibility and average aesthetics.

[0003] To overcome the above problems, some existing tire sidewall tread patterns use a tread structure composed of fine textures (a special arrangement of strip-shaped protrusions with a width of 2mm or even smaller in high density) to achieve a special appearance effect through the contrast difference created by the light and shadow effect. However, the above design method has the following two problems:

[0004] 1. The formation of the above-mentioned fine texture actually relies on the corresponding mold. In order to obtain a better contrast difference, it is necessary to design very fine patterns (grooves) on the mold, which leads to an increase in the processing cost of the mold.

[0005] 2. Fine-textured molds are not only prone to wear during use (resulting in a deterioration of the visual effect), thus affecting the mold's lifespan, but they are also more susceptible to damage from minor bumps and knocks. Once damaged, they are essentially irreparable, significantly increasing the processing cost of tires. Utility Model Content

[0006] The main objective of this invention is to provide a tire that addresses the problem that existing designs aimed at improving the aesthetic appearance of tires can lead to increased processing costs.

[0007] To achieve the above objectives, this utility model provides a tire, comprising: a sidewall, having a tire side surface; an annular protrusion structure, shaped like a boss, disposed on the side surface, the annular protrusion structure being arranged around the central axis of the tire, the upper surface of the annular protrusion structure away from the side surface forming a pattern arrangement surface opposite to the side surface, the pattern arrangement surface having a first arrangement surface and a second arrangement surface connected to each other, the first arrangement surface being used to form a pattern, the first arrangement surface displaying a first color, the second arrangement surface displaying a second color, the color of the side surface and the second color being different from the first color; the first arrangement surface being annularly arranged and surrounding the central axis, the edge line of the first arrangement surface being an annular line, the annular line extending to... A small portion includes multiple straight line segments, the endpoints of which are spliced ​​to form bends, and the multiple bends are spaced apart along the periphery of the annular line; wherein, a first recess is provided on the pattern arrangement surface, the first recess extends to the outer peripheral surface of the annular protrusion structure to form a first boss on the annular protrusion structure, the pattern arrangement surface of the first boss forms the first arrangement surface, and the inner wall of the first recess forms the second arrangement surface; or, a second recess is provided on the pattern arrangement surface, the inner wall of the second recess has a predetermined distance from the outer peripheral surface of the annular protrusion structure, the inner wall of the second recess forms the first arrangement surface, and the portion of the pattern arrangement surface without the second recess forms the second arrangement surface.

[0008] By employing this structural arrangement, at least a portion of the annular line comprises multiple straight line segments, with the endpoints of each segment joined to form bends. These bends are spaced apart along the periphery of the annular line. This arrangement of bends makes the edge line more visually prominent, further improving the visual effect. Specifically, the bends increase the radial dimension of the edge line, creating a wider annular area when the tire rotates, enhancing the visual effect without increasing the area of ​​the first surface. Correspondingly, when the tire rotates, if the edge lines are all annular, the shape during rotation is also an annular, and the static and dynamic patterns are consistent. If at least a portion of the edge line comprises multiple straight line segments, the shape formed during rotation is an annular line generated by the rotation of multiple straight line segments. For the same radius, the width of the annular pattern formed by the straight line segments is wider, thus requiring a smaller pigment area. This achieves the technical effect of displaying a larger pattern area during rotation, even when the pattern on the first surface is small, increasing visual impact and prominence. Furthermore, due to the inclusion of straight segments, the pattern will exhibit different visual effects depending on the tire's rotational speed. The higher the rotational speed, the more regular the outer perimeter of the corresponding toroidal surface will be; the lower the rotational speed, the more irregular the outer perimeter of the corresponding toroidal surface will be, resulting in some bumps and potholes. Therefore, this design also facilitates the judgment of the tire's rotational speed.

[0009] Furthermore, along the radial direction L of the tire, the annular protrusion structure has a maximum width W, which satisfies: 10mm ≤ W ≤ 150mm.

[0010] Furthermore, the edge line of the first arrangement surface includes an inner loop and an outer loop; wherein, the inner loop of the first arrangement surface is composed of multiple interconnected straight lines; or, the inner loop of the first arrangement surface is a curve; or, the inner loop of the first arrangement surface is composed of interconnected straight lines and curves; the outer loop of the first arrangement surface is composed of multiple interconnected straight lines; or, the outer loop of the first arrangement surface is a curve; or, the outer loop of the first arrangement surface is composed of interconnected straight lines and curves.

[0011] Furthermore, the inner ring of the first arrangement surface includes a plurality of first straight line segments connected end to end, and the outer ring of the first arrangement surface includes a plurality of second straight line segments connected end to end. Two adjacent first straight line segments are connected to form a first bend apex, and two adjacent second straight line segments are connected to form a second bend apex. The plurality of first bend apex and the plurality of second bend apex are arranged in a one-to-one correspondence, and each first bend apex and the corresponding second bend apex are arranged opposite to each other or offset radially. And / or, the first bend apex is less than or equal to the second bend apex.

[0012] This structural arrangement, with each first bend apex opposite its corresponding second bend apex, facilitates optimization of the overall layout's uniformity and symmetry, enhancing visual appeal. The first bend apex is smaller than the second bend apex, and it protrudes away from the inner ring surface. This results in a greater radial width at the corresponding position of the first bend apex, allowing for a wider pattern to be displayed during rotation, thus optimizing the visual effect.

[0013] Furthermore, the lengths of the first line segments are equal, the number of the first line segments is n1, and the central angle corresponding to the first line segment is 360° / n1; and / or, the lengths of the second line segments are equal, the number of the second line segments is n2, and the central angle corresponding to the second line segment is 360° / n2.

[0014] This structural arrangement facilitates the formation of a continuous circular shape by multiple first straight segments, optimizing the structural layout and improving the uniformity and symmetry of the overall arrangement. Furthermore, this arrangement also allows multiple second straight segments to form a continuous circular shape, further optimizing the structural layout and improving its uniformity and symmetry.

[0015] Furthermore, the first arrangement surface includes a plurality of interconnected sub-planes, each of the sub-planes being polygonal in shape, and the center point of each sub-plane having a distance L2 between it and the central axis; wherein, in two adjacent sub-planes, the distance L2 of one sub-plane is different from the distance L2 of the other sub-plane.

[0016] Furthermore, the inner and outer loops of the first arrangement surface are both composed of interconnected straight lines and curves, and the first arrangement surface has a notch and / or a convex surface; wherein, the straight lines of the inner loop of the first arrangement surface form at least a portion of the notch and / or the convex surface; and / or, the straight lines of the outer loop of the first arrangement surface form at least a portion of the notch and / or the convex surface.

[0017] This structural design ensures that the display effect of the pattern on the first arrangement surface is maintained during rotation while reducing the area of ​​the first arrangement surface, thus guaranteeing the effect of the pattern. At the same time, it increases the aesthetics and symmetry of the pattern on the first arrangement surface when it is static.

[0018] Furthermore, the inner ring of the first arrangement surface includes a plurality of first curves, a plurality of second curves, and a plurality of third straight lines. The plurality of first curves and the plurality of second curves are spaced apart along the radial direction of the tire. The plurality of first curves and the plurality of second curves are spaced apart circumferentially. Each first curve and its corresponding second curve are staggered circumferentially. A third straight line is provided between adjacent first curves and second curves to form at least a portion of the gap. The connection between the third straight line and the first curve forms a third bend apex angle, and the connection between the third straight line and the second curve forms a fourth bend apex angle. ; and / or, the outer ring of the first arrangement surface includes a plurality of third curves, a plurality of fourth curves, and a plurality of fourth straight lines. The plurality of third curves and the plurality of fourth curves are spaced apart along the radial direction of the tire. The plurality of third curves and the plurality of fourth curves are spaced apart circumferentially. Each third curve and its corresponding fourth curve are staggered circumferentially. A fourth straight line is provided between adjacent third curves and fourth curves to form at least a portion of the notch. The connection between the fourth straight line and the third curve forms a fifth bend apex angle, and the connection between the fourth straight line and the fourth curve forms a sixth bend apex angle. Specifically, the first curve, the second curve, the third curve, and the fourth curve are all arc segments, and the radii of the arc segments corresponding to the first curve, the second curve, the third curve, and the fourth curve are not equal.

[0019] This structural design, with its inner and outer rings, facilitates optimization of their layout, enhancing their visual appeal when stationary and making the pattern on the first surface more prominent. Furthermore, this design ensures that the pattern on the first surface maintains a certain radial width during tire rotation, guaranteeing visual quality and preserving its appearance. Moreover, the effects of the third, fourth, fifth, and sixth bends differ with rotational speed; at higher speeds, these bends form regular circular edges, while at lower speeds, they form irregular circular edges.

[0020] Further, the inner ring of the first arrangement surface includes a plurality of fifth curves and a plurality of first bend straight segments. The plurality of fifth curves are spaced apart along the radial direction of the tire and spaced apart circumferentially. A first bend straight segment is provided between two adjacent fifth curves, and the first bend straight segment forms at least a portion of the gap; and / or, the inner ring of the first arrangement surface includes a plurality of sixth curves and a plurality of second bend straight segments. The plurality of sixth curves are spaced apart along the radial direction of the tire and spaced apart circumferentially. A second bend straight segment is provided between two adjacent fifth curves, and the second bend straight segment forms at least a portion of the gap.

[0021] This structural design, with its inner and outer rings, facilitates optimization of their layout, improves their visual appeal when stationary, and makes the pattern on the first surface more prominent. Furthermore, this design ensures that the pattern on the first surface maintains a certain radial width while the tire is rotating, preserving its visual appeal and allowing it to adapt to changes in speed, forming specific shapes accordingly.

[0022] Furthermore, the tire sidewall has an annular arrangement area, which is arranged around the central axis of the tire, and the annular protrusion structure is arranged within the annular arrangement area; wherein, the annular arrangement area is located between the upper parting line of the tire sidewall and the rim protection of the tire sidewall; or, the annular arrangement area is located between the upper parting line of the tire sidewall and the waterproof line of the tire sidewall.

[0023] Applying the technical solution of this utility model, the tire sidewall has a tire side surface, and an annular protrusion structure is disposed on the side surface and arranged around the central axis of the tire. The annular protrusion structure has a pattern arrangement surface arranged opposite to the side surface. The pattern arrangement surface has a first arrangement surface and a second arrangement surface that are interconnected. The first arrangement surface is used to form a pattern and displays a first color, while the second arrangement surface displays a second color. The color of the side surface and the second color are both different from the first color. The annular protrusion structure has a maximum width W along the radial direction L of the tire, and the maximum width W satisfies the following condition: 10mm ≤ W ≤ 150mm. In this way, this application, on the one hand, forms a corresponding pattern by using a first arrangement surface with a color different from both the second arrangement surface and the side surface, making the contrast between the pattern and the second arrangement surface and the side surface stronger, thereby initially improving the tire's appearance aesthetics; on the other hand, it utilizes an annular raised structure to create a height difference between the first arrangement surface and the side surface, making the pattern on the first arrangement surface more prominent and able to create a light and shadow effect, further improving the tire's appearance aesthetics; based on this, this application further limits the width of the annular raised structure to ensure that the overall size of the annular raised structure is more appropriate, thereby improving the visual experience of the annular raised structure (too large will appear abrupt, while too small will be inconspicuous). The above settings comprehensively ensure that the tire has a high overall appearance aesthetics, without the need to use the texture pattern design in the prior art, so that the corresponding molding mold only needs to set the corresponding molding recess for the annular raised structure, rather than a fine tread pattern, thereby extending the service life of the molding mold and reducing its processing cost, thus solving the problem that the design schemes used in the prior art to improve the appearance aesthetics of the tire will lead to an increase in the tire's processing cost.

[0063] To address the problem that existing designs for improving tire aesthetics lead to increased tire manufacturing costs, this application provides a tire design.

[0064] Example 1

[0065] like Figures 1 to 5 As shown, the tire includes a sidewall 10 and an annular protrusion structure 20. The sidewall 10 has a sidewall 1. The annular protrusion structure 20 is disposed on the sidewall 1, and is arranged around the central axis of the tire and has a pattern arrangement surface 21 opposite to the sidewall 1. The pattern arrangement surface 21 has a first arrangement surface 211 and a second arrangement surface 212 that are interconnected. The first arrangement surface 211 is used to form a pattern and is a first color. The second arrangement surface 212 is a second color. The color of the sidewall 1 and the second color are both different from the first color. The annular protrusion structure 20 has a maximum width W along the radial direction L of the tire, and the maximum width W satisfies: 10mm ≤ W ≤ 150mm.

[0066] Applying the technical solution of this embodiment, the tire sidewall 10 is disposed on the tire, forming the tire sidewall 1. An annular protrusion structure 20 is disposed on the sidewall 1 and arranged around the central axis of the tire. The annular protrusion structure 20 has a pattern arrangement surface 21 disposed opposite to the sidewall 1. The pattern arrangement surface 21 has a first arrangement surface 211 and a second arrangement surface 212 that are interconnected. The first arrangement surface 211 is used to form a pattern and displays a first color. The second arrangement surface 212 displays a second color. The color of the sidewall 1 and the second color are both different from the first color. Along the radial direction L of the tire, the annular protrusion structure has a maximum width W, which satisfies the following condition: 10mm ≤ W ≤ 150mm. Thus, in this embodiment, on the one hand, the pattern is formed by the first arrangement surface 211, which presents a different color from both the second arrangement surface 212 and the side surface 1, making the contrast between the pattern and the second arrangement surface 212 and the side surface 1 stronger, thereby initially improving the aesthetic appearance of the tire; on the other hand, the annular protrusion structure 20 is used to create a height difference between the first arrangement surface 211 and the side surface 1, making the pattern on the first arrangement surface 211 more prominent and able to form a light and shadow effect, further improving the aesthetic appearance of the tire; based on this, this embodiment further limits the width of the annular protrusion structure 20. To ensure that the overall size of the annular protrusion structure 20 is appropriate, thereby improving the visual experience of the annular protrusion structure 20 (too large and it will look abrupt, while too small and it will not be obvious), the above settings comprehensively ensure that the tire has a high overall aesthetic appearance. There is no need to use the texture pattern design in the prior art, so that the corresponding molding mold only needs to set the corresponding molding recess for the annular protrusion structure 20, rather than a fine tread pattern. This extends the service life of the molding mold, reduces its processing cost, and solves the problem that the design scheme of the prior art to improve the aesthetic appearance of the tire will lead to an increase in the tire processing cost.

[0067] In this embodiment, the second color of the second arrangement surface 212 and the color of the side surface 1 are both black, which is the color of the tire rubber material. The first color of the first arrangement surface 211 does not have to be black.

[0068] It should be noted that the color of the second arrangement surface 212 can also be a non-black color, so that the first arrangement surface 211, the second arrangement surface 212 and the side surface 1 form three different colors, further enhancing the visual appeal.

[0069] Specifically, there are various ways to form the colored pattern on the first arrangement surface 211, such as:

[0070] Formation Method 1: Colored rubber can be used in the tire processing process, that is, colored rubber is used in the extrusion step to form a colored layer inside the tire body or colored rubber sheets are pasted before the vulcanization step to form a colored layer on the tire body surface. After the tire vulcanization is completed, the surface rubber of the annular protrusion structure 20 is polished and removed so that the colored layer forms the corresponding pattern.

[0071] Formation Method 2: During normal tire processing, after the tire vulcanization is completed, the first arrangement surface 211 is polished to increase its surface roughness, and then the corresponding pattern is formed by means such as printing, brushing or attaching colored parts.

[0072] Method 3: In the early stages of tire design, the surface roughness of the mold that forms the first arrangement surface 211 is improved so that the first arrangement surface 211 with a larger surface roughness can be formed after the tire vulcanization is completed. Then, the corresponding pattern is formed by means such as printing, painting or attaching colored parts.

[0073] like Figures 1 to 5 As shown, the annular protrusion structure 20 is in the shape of a boss. The upper surface of the annular protrusion structure 20 away from the side 1 forms a pattern arrangement surface 21. A first recess 24 is provided on the pattern arrangement surface 21. The first recess 24 extends to the outer peripheral surface of the annular protrusion structure 20 to form a first boss portion 25 on the annular protrusion structure 20. The pattern arrangement surface 21 of the first boss portion 25 forms a first arrangement surface 211, and the inner wall of the first recess 24 forms a second arrangement surface 212. In this way, with the side 1 as the reference plane, the first arrangement surface 211 is higher than the second arrangement surface 212, so that the first arrangement surface 211 receives more light and the displayed colors are brighter, thus creating a prominent and bright visual effect.

[0074] In this embodiment, the maximum width W is the bottom width of the annular protrusion structure 20.

[0075] In this embodiment, the pattern arrangement surface 21 is arranged in a ring shape.

[0076] Specifically, in this embodiment, the first arrangement surface 211 can be processed using the first forming method, that is, after the tire vulcanization is completed, the upper surface of the first boss portion 25 is partially polished and removed to expose the internal colored rubber layer, thereby forming a colored pattern.

[0077] Specifically, when designing a tire forming mold, the first arrangement surface 211 of the corresponding shape can be formed by designing the forming recess for forming the annular protrusion structure 20 part into the corresponding shape.

[0078] Optionally, there may be multiple first arrangement surfaces 211, which are spaced apart around a central axis to form a marking pattern 23. The first arrangement surfaces 211 may be elliptical, polygonal, or composed of interconnected straight lines and curves. This arrangement allows for greater flexibility and variety in the shape and number of the first arrangement surfaces 211, resulting in a wider variety of marking patterns 23 and thus enhancing the design flexibility of the tire sidewall.

[0079] In this embodiment, the first arrangement surface 211 is a polygon, specifically, the first arrangement surface 211 is an isosceles trapezoid.

[0080] It should be noted that the shape of the first arrangement surface 211 is not limited to this. It can be adjusted according to working conditions and usage requirements to form more diverse marking patterns 23, which also improves the design flexibility of the tire sidewall style.

[0081] Specifically, in two adjacent first arrangement surfaces 211, the bottom edges of the first arrangement surfaces 211 face opposite directions, that is, the waists of the two adjacent first arrangement surfaces 211 are arranged parallel to each other.

[0082] like Figure 2 and Figure 3 As shown, there is a distance L1 between the center point of the first arrangement surface 211 and the central axis. In two adjacent first arrangement surfaces 211, the distance L1 of one first arrangement surface 211 is different from that of the other first arrangement surface 211. In this way, the above arrangement creates a staggered distance between two adjacent first arrangement surfaces 211 on the circular arrangement trajectory of multiple first arrangement surfaces 211, further improving the visual effect of the marking pattern 23.

[0083] like Figure 3 As shown, in the marking pattern 23 formed by multiple first arrangement surfaces 211, there is a minimum distance e between it and the upper ring line of the pattern arrangement surface 21, and the minimum distance e satisfies: e≥2mm. There is a minimum distance f between it and the lower ring line of the pattern arrangement surface 21, and the minimum distance f satisfies: f≥2mm. The above size setting can not only reduce the difficulty of tire manufacturing, but also ensure that a clear and complete corresponding pattern is formed on the first arrangement surface 211.

[0084] Specifically, during the tire molding and vulcanization process, if a colored rubber layer is formed inside the tire body (as is the case in this embodiment), the above-mentioned size setting can prevent uneven rubber flow due to excessive rubber flow distance, i.e., black rubber flows into the colored rubber, thereby causing the pattern on the first arrangement surface 211 to expose the black rubber.

[0085] Specifically, during the tire molding and vulcanization process, if colored films are pasted on the outer surface of the tire body, the above-mentioned size settings can facilitate the precise positioning of the colored films, preventing the pattern from being exposed by black glue, resulting in an unclear or incomplete pattern; or the colored glue overflowing, causing irregular colored patterns formed by the overflowing glue on the outer side of the pattern, thus leading to appearance defects.

[0086] Specifically, if patterns are formed by printing, painting, or other methods, the above-mentioned size settings can prevent the problem of partial missing parts caused by pattern misalignment.

[0087] like Figure 1 As shown, the tire sidewall 10 has an annular arrangement area 11, which is arranged around the central axis of the tire. An annular protrusion structure 20 is disposed within the annular arrangement area 11. The annular arrangement area 11 is located between the upper parting line 12 of the tire sidewall 10 and the rim protection 13 of the tire sidewall 10; or, the annular arrangement area 11 is located between the upper parting line 12 of the tire sidewall 10 and the waterproof line of the tire sidewall 10. This arrangement further limits the placement of the annular protrusion structure 20 to suit the user's viewing angle, further enhancing the tire's aesthetic appearance.

[0088] Example 2

[0089] The tire in Embodiment 2 differs from that in Embodiment 1 in that the misalignment distance between the two adjacent first arrangement surfaces 211 is different.

[0090] like Figure 6 As shown, the misalignment distance formed between two adjacent first arrangement surfaces 211 on the circular arrangement trajectory of multiple first arrangement surfaces 211 is larger than the misalignment distance in Embodiment 1, so as to form more diverse marking patterns 23, thereby improving the design flexibility of the tire sidewall style.

[0091] Example 3

[0092] The tire in Embodiment 3 differs from that in Embodiment 1 in that the misalignment distance between two adjacent first arrangement surfaces 211 is different.

[0093] like Figure 7 As shown, the distance L1 of each first arrangement surface 211 is the same, that is, the misalignment distance formed between two adjacent first arrangement surfaces 211 on the circular arrangement trajectory of multiple first arrangement surfaces 211 is zero, so as to form more diverse marking patterns 23, thereby improving the design flexibility of the tire sidewall style.

[0094] Example 4

[0095] The tire in Example 4 differs from that in Example 2 in that the shape of the first arrangement surface 211 is different.

[0096] like Figure 8 As shown, in this embodiment, the first arrangement surface 211 is triangular, and the two adjacent first arrangement surfaces 211 form a staggered distance on the circular arrangement trajectory of multiple first arrangement surfaces 211 to form more diverse marking patterns 23, thereby improving the design flexibility of the tire sidewall style.

[0097] Example 5

[0098] The tire in Embodiment 5 differs from that in Embodiment 4 in that the misalignment distance between two adjacent first arrangement surfaces 211 is different.

[0099] like Figure 9 As shown, the distance L1 of each first arrangement surface 211 is the same, that is, the misalignment distance formed between two adjacent first arrangement surfaces 211 on the circular arrangement trajectory of multiple first arrangement surfaces 211 is zero, so as to form more diverse marking patterns 23, thereby improving the design flexibility of the tire sidewall style.

[0100] Example 6

[0101] The tire in Example 6 differs from that in Example 5 in that the shape of the first arrangement surface 211 is different.

[0102] like Figure 10 As shown, in this embodiment, the first arrangement surface 211 is circular, and the misalignment distance between two adjacent first arrangement surfaces 211 on the circular arrangement trajectory of multiple first arrangement surfaces 211 is zero, so as to form more diverse marking patterns 23, thereby improving the design flexibility of the tire sidewall style.

[0103] Example 7

[0104] The tire in Example 7 differs from that in Example 6 in that the shape of the first arrangement surface 211 is different.

[0105] like Figure 11 As shown, in this embodiment, the misalignment distance between two adjacent first arrangement surfaces 211 on the circular arrangement trajectory of multiple first arrangement surfaces 211 is zero, and the first arrangement surface 211 is an irregular shape composed of interconnected straight lines and curves to form more diverse marking patterns 23, thereby improving the design flexibility of the tire sidewall style.

[0106] Example 8

[0107] The tire in Embodiment 8 differs from that in Embodiment 7 in that the shape of the first arrangement surface 211 is different and the arrangement of the multiple first arrangement surfaces 211 is different.

[0108] like Figure 12As shown, the first arrangement surface 211 is rectangular, and the logo pattern 23 includes multiple pattern forming groups 231. Each pattern forming group 231 includes multiple adjacent first arrangement surfaces 211, wherein the spacing between two adjacent pattern forming groups 231 is greater than the spacing between two adjacent first arrangement surfaces 211. In this way, the above arrangement makes the logo pattern 23 more flexible and diverse, so as to form a more complex visual effect.

[0109] Specifically, the pattern forming group 231 is actually a symmetrical figure, and the length of the first arrangement surface 211, which is arranged in a rectangle, gradually decreases along the direction away from its axis of symmetry.

[0110] It should be noted that the arrangement of multiple pattern forming groups 231 and the arrangement and corresponding shapes of multiple first arrangement surfaces 211 within a pattern forming group 231 are not limited to this, and can be adjusted accordingly according to the usage requirements and the logo pattern 23 to be formed.

[0111] Example 9

[0112] The tire in Example 9 differs from that in Example 1 in that the number of first arrangement surfaces 211 is different.

[0113] like Figure 13 As shown, the first arrangement surface 211 is arranged in a ring shape, and the first arrangement surface 211 is arranged around the central axis. The inner ring of the first arrangement surface 211 is composed of multiple interconnected straight lines; the outer ring of the first arrangement surface 211 is also composed of multiple interconnected straight lines. This arrangement allows the first arrangement surface 211 to form a continuous ring pattern, further enhancing the diversity of the marking pattern 23 and the design flexibility of the tire sidewall style.

[0114] In this embodiment, the inner and outer ring lines of the first arrangement surface 211 are both composed of multiple interconnected straight lines, and the first arrangement surface 211 is a polygonal ring.

[0115] Specifically, the inner ring of the first arrangement surface 211 includes multiple first straight line segments connected end to end, and the outer ring of the first arrangement surface 211 includes multiple second straight line segments connected end to end. Adjacent two first straight line segments are connected to form a first bend apex, and adjacent two second straight line segments are connected to form a second bend apex. The multiple first bend apex and multiple second bend apex are arranged in a one-to-one correspondence, with each first bend apex and its corresponding second bend apex being arranged opposite to each other or radially offset; and / or, the first bend apex is less than or equal to the second bend apex.

[0116] Specifically, multiple first line segments have the same length, the number of first line segments is n1, and the central angle corresponding to the first line segment is 360° / n1; and / or, multiple second line segments have the same length, the number of second line segments is n2, and the central angle corresponding to the second line segment is 360° / n2.

[0117] Example 10

[0118] The tire in Example 10 differs from that in Example 9 in that the shape of the first arrangement surface 211 is different.

[0119] like Figure 14 As shown, the inner ring of the first arrangement surface 211 is composed of multiple interconnected straight lines; the outer ring of the first arrangement surface 211 is also composed of multiple interconnected straight lines. The first arrangement surface 211 includes multiple interconnected sub-planes 2111, each sub-plane 2111 being polygonal in shape, with a distance L2 between the center point of each sub-plane 2111 and the central axis. In adjacent sub-planes 2111, the distance L2 between one sub-plane 2111 and the other sub-plane 2111 is different. Thus, this arrangement ensures that the first arrangement surface 211 is ring-shaped while simultaneously creating a staggered distance between the multiple sub-planes 2111 along the ring-shaped trajectory of the first arrangement surface 211, making the marking pattern 23 more flexible and diverse, resulting in a more complex visual effect.

[0120] Specifically, the inner ring of the first arrangement surface 211 includes a plurality of first curves, a plurality of second curves, and a plurality of third straight lines. The plurality of first curves and the plurality of second curves are spaced apart along the radial direction of the tire, and the plurality of first curves and the plurality of second curves are spaced apart along the circumferential direction. Each first curve and its corresponding second curve are staggered along the circumferential direction. A third straight line is provided between adjacent first curves and second curves to form at least a portion of the gap 2112. The connection between the third straight line and the first curve forms a third bend apex angle, and the connection between the third straight line and the second curve forms a fourth bend apex angle. And / or, the outer ring of the first arrangement surface 211 includes a plurality of third curves, a plurality of fourth curves, and a plurality of fourth straight lines. The plurality of third curves and the plurality of fourth curves are spaced apart along the radial direction of the tire, and the plurality of third curves and the plurality of fourth curves are spaced apart along the circumferential direction. Each third curve and its corresponding fourth curve are staggered along the circumferential direction. A fourth straight line is provided between adjacent third curves and fourth curves to form at least a portion of the gap 2112. The connection between the fourth straight line and the third curve forms a fifth bend apex angle, and the connection between the fourth straight line and the fourth curve forms a sixth bend apex angle.

[0121] Example 11

[0122] The tire in Example 11 differs from that in Example 10 in that the shape of the first arrangement surface 211 is different.

[0123] like Figure 15 As shown, the inner and outer ring lines of the first arrangement surface 211 are both composed of interconnected straight lines and curves, and the first arrangement surface 211 has a notch 2112 and / or a convex surface. In this way, the above arrangement ensures that the first arrangement surface 211 is arranged in a ring shape, while making the marking pattern 23 more flexible and diverse, so as to form a more complex visual effect.

[0124] In this embodiment, the first arrangement surface 211 has a notch 2112, which is triangular in shape.

[0125] Specifically, the straight line of the inner ring of the first arrangement surface 211 forms at least a portion of the notch 2112 and / or the convex surface; and / or, the straight line of the outer ring of the first arrangement surface 211 forms at least a portion of the notch 2112 and / or the convex surface.

[0126] Specifically, the inner ring of the first arrangement surface 211 includes a plurality of fifth curves and a plurality of first bent straight segments. The plurality of fifth curves are spaced apart along the radial direction of the tire and spaced apart along the circumferential direction. A first bent straight segment is provided between two adjacent fifth curves, and the first bent straight segment forms at least a portion of the notch 2112; and / or, the inner ring of the first arrangement surface 211 includes a plurality of sixth curves and a plurality of second bent straight segments. The plurality of sixth curves are spaced apart along the radial direction of the tire and spaced apart along the circumferential direction. A second bent straight segment is provided between two adjacent fifth curves, and the second bent straight segment forms at least a portion of the notch 2112.

[0127] Specifically, the first bent straight segment includes two straight segments connected at a first predetermined angle, and the second bent straight segment includes two straight segments connected at a second predetermined angle.

[0130] like Figures 16 to 20As shown, a second recess 26 is provided on the pattern arrangement surface 21. The inner wall of the second recess 26 is at a predetermined distance from the outer peripheral surface of the annular protrusion structure 20. The inner wall of the second recess 26 forms the first arrangement surface 211, and the portion of the pattern arrangement surface 21 without the second recess 26 forms the second arrangement surface 212. In this way, with the side surface 1 as the reference surface, the first arrangement surface 211 is lower than the second arrangement surface 212, so that the first arrangement surface 211 is not easily scratched and the surface of the colored adhesive is smooth, thereby forming a more diverse visual effect.

[0131] Specifically, the portion without the second recess 26 actually protrudes relative to the bottom wall of the second recess 26 to form a second boss 27, and the upper surface of the second boss 27 away from the side 1 is the second arrangement surface 212.

[0132] In this embodiment, the first arrangement surface 211 is actually processed using the first method, that is, colored film is pasted on the tire body surface to form a colored layer before the tire vulcanization step. After the tire vulcanization is completed, the surface rubber of the annular protrusion structure 20 is polished and removed. Since the first arrangement surface 211 is lower than the second arrangement surface 212, the colored layer in the first arrangement surface 211 is retained, thereby forming the corresponding pattern.

[0133] It should be noted that the shape, number and arrangement of the first arrangement surface 211 in this embodiment are the same as those in Embodiment 1.

The inner wall of the second recess 26 is at a predetermined distance from the outer peripheral surface of the annular protrusion structure 20. The inner wall of the second recess 26 forms the first arrangement surface 211, and the portion of the pattern arrangement surface 21 without the second recess 26 forms the second arrangement surface 212.

[0169] It should be noted that the shape, number and arrangement of the first arrangement surface 211 in this embodiment are the same as those in embodiment ten.

[0170] Example 22

[0171] The tire in Example 22 differs from that in Example 11 in that the structure of the annular protrusion 20 is different.

[0172] like Figure 30 As shown, a second recess 26 is provided on the pattern arrangement surface 21. The inner wall of the second recess 26 is at a predetermined distance from the outer peripheral surface of the annular protrusion structure 20. The inner wall of the second recess 26 forms the first arrangement surface 211, and the portion of the pattern arrangement surface 21 without the second recess 26 forms the second arrangement surface 212.

[0173] It should be noted that the shape, number and arrangement of the first arrangement surface 211 in this embodiment are the same as those in Embodiment Eleven.

[0174] Example 23

[0175] The tire in Example 23 differs from that in Example 1 in that the structure of the annular protrusion 20 is different.

[0176] like Figure 31 As shown, the pattern arrangement surface 21 is a flat or curved surface. The height between the first arrangement surface 211 and the second arrangement surface 212 is almost the same (completely the same when flat). Only between the pattern arrangement surface 21 and the side surface 1 is a relatively strong light and shadow effect formed, thus creating a more diverse visual experience.

[0177] It should be noted that the shape, number and arrangement of the first arrangement surface 211 in this embodiment can also be arranged according to the shape, number and arrangement of the first arrangement surface 211 in Embodiments 1 to 11 to form a variety of different marking patterns 23.

[0178] Specifically, the pattern of the first arrangement surface 211 in this embodiment can be formed in accordance with the second and third formation methods.

[0179] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0180] The tire sidewall is mounted on the tire and has the sidewall of the tire. An annular protrusion structure is mounted on the sidewall and arranged around the central axis of the tire. The annular protrusion structure has a pattern arrangement surface opposite to the sidewall. The pattern arrangement surface has a first arrangement surface and a second arrangement surface that are interconnected. The first arrangement surface is used to form the pattern and is a first color. The second arrangement surface is a second color. The color of the sidewall and the second color are both different from the first color. The annular protrusion structure has a maximum width W along the radial direction L of the tire, and the maximum width W satisfies the following condition: 10mm ≤ W ≤ 150mm. In this way, this application, on the one hand, forms a corresponding pattern by using a first arrangement surface with a color different from both the second arrangement surface and the side surface, making the contrast between the pattern and the second arrangement surface and the side surface stronger, thereby initially improving the tire's appearance aesthetics; on the other hand, it utilizes an annular raised structure to create a height difference between the first arrangement surface and the side surface, making the pattern on the first arrangement surface more prominent and able to create a light and shadow effect, further improving the tire's appearance aesthetics; based on this, this application further limits the width of the annular raised structure to ensure that the overall size of the annular raised structure is more appropriate, thereby improving the visual experience of the annular raised structure (too large will appear abrupt, while too small will be inconspicuous). The above settings comprehensively ensure that the tire has a high overall appearance aesthetics, without the need to use the texture pattern design in the prior art, so that the corresponding molding mold only needs to set the corresponding molding recess for the annular raised structure, rather than a fine tread pattern, thereby extending the service life of the molding mold and reducing its processing cost, thus solving the problem that the design schemes used in the prior art to improve the appearance aesthetics of the tire will lead to an increase in the tire's processing cost.
