Description

Technical Field

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

[0002] Currently, as one of the vehicle's exposed components, tires, in addition to their regular driving capabilities, are primarily used to decorate the vehicle and enhance its aesthetic appeal. In existing technologies, the tire sidewalls or treads are usually designed with specific patterns and structures tailored to the brand and vehicle type to reflect the brand image and the appearance characteristics of the corresponding vehicle type.

[0003] However, tires are usually entirely black. Although they have tread patterns on their outer surface, the outer surface (especially the sidewalls) is generally designed with a smooth finish. The inherent defects in their optical properties result in a very poor visual appearance of the corresponding tread patterns. The main inherent defects are as follows:

[0004] On the one hand, a smooth black surface has high specular reflection characteristics, which easily forms strong directional reflection under illumination (and the reflection only occurs once), resulting in an imbalance between the intensity of incident light and the marking area (the patterned area). On the other hand, the reflectivity of incident light is too high, resulting in a large difference between the brightness values ​​of the marking area (the patterned area) and the background area (the outer surface of the tire without a tread structure) and the pure black reference value (in other words, black does not appear black to the naked eye due to the aforementioned inherent defects). Moreover, the brightness difference ΔL between the two is close to zero, which significantly weakens the optical contrast of the marking information and is very likely to cause misreading or recognition delay.

[0005] It is evident that the aforementioned inherent defects result in extremely poor improvement in the aesthetic appearance of the tread pattern structure on the outer surface of the tire in the prior art. Utility Model Content

[0006] The main objective of this invention is to provide a tire that addresses the problem of poor aesthetic enhancement of the tread pattern on the outer surface of existing tires.

[0007] To achieve the above objectives, this utility model provides a tire tread structure. The tire has a surface, and a tire tread structure protruding from the surface is provided on the surface. The tire tread structure forms at least part of the outer surface of the tire. The tire tread structure includes: a first strip-shaped light-absorbing element, which is curved and arranged along a preset trajectory to form a marking pattern; the portion of the surface without the first strip-shaped light-absorbing element forms a surface to be filled; a light-absorbing assembly, which is disposed on the surface to be filled, with the first strip-shaped light-absorbing element inserted within it. The light-absorbing assembly has a strip-shaped light-absorbing recess communicating with the outside world, and there is a light-absorbing recess communicating with the outside world between the light-absorbing assembly and the first strip-shaped light-absorbing element. The first strip-shaped light-absorbing element and the light-absorbing recess are connected to form a drainage path. Both the strip-shaped light-absorbing recess and the light-absorbing recess are used to reflect light beams incident upon them. The strip-shaped light-absorbing recess has a width-to-depth ratio C in its cross-section, and the width-to-depth ratio C satisfies: 0.42≤C≤0.69; wherein the strip-shaped light-absorbing recess is connected to the light-absorbing recess.

[0008] Furthermore, the light-absorbing component includes a plurality of second strip-shaped light-absorbing elements, which extend along a first preset direction and are arranged along a second preset direction, with the first preset direction and the second preset direction forming an angle between them; along the second preset direction, two adjacent second strip-shaped light-absorbing elements surround each other to form a strip-shaped light-absorbing recess; or, two adjacent second strip-shaped light-absorbing elements surround each other with the arrangement surface to form a strip-shaped light-absorbing recess; wherein, the second strip-shaped light-absorbing element has a communicating recess, which is used to connect two adjacent strip-shaped light-absorbing recesses.

[0009] Furthermore, the connecting recess has a first inner sidewall and a second inner sidewall disposed opposite to each other; wherein, there is a distance L1 between the first inner sidewalls of any two connecting recesses, and the distance L1 satisfies: 3mm≤L1≤33mm.

[0010] Furthermore, along the direction away from the arrangement surface, the width of at least part of the second strip light-absorbing element gradually decreases to form a first inclined surface and a second inclined surface on the outer surface of the second strip light-absorbing element. The first inclined surface and the second inclined surface are arranged opposite to each other, and both the first inclined surface and the second inclined surface are used to surround and form the strip light-absorbing recess.

[0011] Furthermore, along the second preset direction, two adjacent second strip-shaped light-absorbing elements surround the arrangement surface to form a strip-shaped light-absorbing recess, and the arrangement surface forms the bottom wall of the strip-shaped light-absorbing recess. The maximum width W1 of the strip-shaped light-absorbing recess satisfies: 0.15mm≤W1≤0.45mm, and the minimum width W2 of the strip-shaped light-absorbing recess satisfies: 0.03mm≤W2≤0.15mm. The second strip-shaped light-absorbing element has a maximum width W3, which satisfies: 0.15mm≤W3≤0.45mm.

[0012] Furthermore, both the first and second inclined surfaces are curved surfaces, and the outer peripheral surface of the second strip light-absorbing element also includes a first arcuate surface located between the first and second inclined surfaces. The first inclined surface is connected to the second inclined surface through the first arcuate surface. The end of the first inclined surface away from the first arcuate surface is connected to the arrangement surface, and the end of the second inclined surface away from the first arcuate surface is connected to the arrangement surface. Alternatively, both the first and second inclined surfaces are curved surfaces, and the outer peripheral surface of the second strip light-absorbing element also includes a second arcuate surface, a first plane, and a second plane. The second arcuate surface is located between the first and second inclined surfaces. The first inclined surface is connected to the second inclined surface through the second arcuate surface. The first inclined surface is connected to the arrangement surface through the first plane, and the second inclined surface is connected to the arrangement surface through the second plane. The first plane and the second plane are arranged opposite to each other, and the distance between the first plane and the second plane gradually decreases along the direction away from the arrangement surface.

[0013] Furthermore, there are multiple light-absorbing recesses. Along the direction away from the arrangement surface, at least part of the width of the first strip light-absorbing element gradually decreases to form a third inclined surface and a fourth inclined surface on the outer surface of the first strip light-absorbing element. The third inclined surface and the fourth inclined surface are arranged opposite to each other. Among them, the third inclined surface surrounds and forms a light-absorbing recess with the end face of the second strip light-absorbing element located on one side of the first strip light-absorbing element and the arrangement surface; or, the third inclined surface surrounds and forms a light-absorbing recess with the end face of the second strip light-absorbing element located on one side of the first strip light-absorbing element; the fourth inclined surface surrounds and forms another light-absorbing recess with the end face of the second strip light-absorbing element located on the other side of the first strip light-absorbing element and the arrangement surface; or, the fourth inclined surface surrounds and forms another light-absorbing recess with the end face of the second strip light-absorbing element located on the other side of the first strip light-absorbing element.

[0014] Furthermore, both the third and fourth inclined surfaces are curved surfaces, and the outer peripheral surface of the first strip light-absorbing element also includes a third arcuate surface located between the third and fourth inclined surfaces. The third inclined surface is connected to the fourth inclined surface through the third arcuate surface. The end of the third inclined surface away from the third arcuate surface is connected to the arrangement surface, and the end of the fourth inclined surface away from the third arcuate surface is connected to the arrangement surface. Alternatively, both the third and fourth inclined surfaces are curved surfaces, and the outer peripheral surface of the first strip light-absorbing element also includes a fourth arcuate surface, a third plane, and a fourth plane. The fourth arcuate surface is located between the third and fourth inclined surfaces. The third inclined surface is connected to the fourth inclined surface through the fourth arcuate surface. The third inclined surface is connected to the arrangement surface through the third plane, and the fourth inclined surface is connected to the arrangement surface through the fourth plane. The third plane and the fourth plane are arranged opposite to each other, and the distance between the third plane and the fourth plane gradually decreases along the direction away from the arrangement surface.

[0015] Furthermore, the first strip light-absorbing element is arranged in an arc shape and there are multiple of them. The multiple first strip light-absorbing elements include first pattern forming elements. The marking pattern includes sub-patterns. The sub-patterns are combined with the sub-patterns after translation and / or symmetry and / or rotation to form at least a part of the marking pattern. The sub-patterns include: N1 first pattern forming elements. The number of first pattern forming elements N1 is related to the size of the arrangement surface along the first preset direction or the second preset direction. The radius R of the circle corresponding to each first pattern forming element is different. The radius R satisfies: R=N2·SR; where SR is a preset parameter value, N2=1, 2, 3...N, and N is a positive integer. The central angle A corresponding to the first pattern forming element satisfies: 90°≤A≤180°.

[0016] Furthermore, the plurality of first strip light-absorbing elements also include second pattern forming elements, and the sub-patterns further include: a plurality of first arc segments, arranged concentrically, with each first arc segment corresponding to a different radius of circle, and the plurality of first arc segments symmetrical along a preset axis of symmetry and overlapping with each other with N1 first pattern forming elements; wherein, at least one first arc segment is formed by at least two second pattern forming elements spaced apart, and in the first arc segment, the gap between two adjacent second pattern forming elements forms an avoidance gap, which is used to avoid the first pattern forming elements.

[0017] Furthermore, the arrangement surface is located on the tire sidewall and is arranged in a ring shape, and the second strip light-absorbing element of the tire tread structure extends radially along the tire.

[0018] According to the technical solution of this utility model, a tire has a surface with a tread pattern structure protruding from it to form at least part of the outer surface of the tire. The first strip-shaped light-absorbing element of the tread pattern structure is curved and arranged along a preset trajectory to form a marking pattern. The portion of the surface without the first strip-shaped light-absorbing element forms a filling surface. A light-absorbing assembly is disposed on the filling surface. The first strip-shaped light-absorbing element is inserted within the light-absorbing assembly. The light-absorbing assembly has a strip-shaped light-absorbing recess communicating with the outside. A light-absorbing recess communicating with the outside is located between the light-absorbing assembly and the first strip-shaped light-absorbing element. Both the strip-shaped light-absorbing recess and the light-absorbing recess are used to reflect light beams incident upon them. The strip-shaped light-absorbing recess has a width-to-depth ratio C in its cross-section, satisfying: 0.42 ≤ C ≤ 0.69. The strip-shaped light-absorbing recesses are connected to each other. Thus, the first strip-shaped light-absorbing element and light-absorbing assembly protruding from the arrangement surface in this application, while forming the tire tread structure, can reflect the light beam through the strip-shaped light-absorbing recesses. For example, after the light beam enters the strip-shaped light-absorbing recess, the strip-shaped light-absorbing recess with the aforementioned width-to-depth ratio allows the light beam to undergo multiple reflections within it, thereby reducing the inherent optical defects of the tire's outer surface. Specifically, on the one hand, the emission direction of the light beam after multiple reflections is more complex (approximately diffuse reflection), thereby avoiding the strong directional reflection caused by the near-mirror reflection characteristics of the tire's outer surface (the light beam is only reflected once), and increasing the tire tread pattern. The contrast between the tread pattern and the tire's outer surface is enhanced. Furthermore, during multiple reflections, the light beam is absorbed multiple times, resulting in a lower intensity of the emitted beam. This reduces the brightness of the tread pattern, making it darker than the tire's outer surface, creating a strong contrast. This comprehensive design produces a "light trapping effect," ensuring the markings have a significant visual impact on the tire's outer surface and that the corresponding information (such as decorative or branding effects) is quickly captured by the user. This solves the problem of poor aesthetic enhancement of the tread pattern in existing technologies. Simultaneously, the interconnected strip-shaped light-absorbing recesses and the spaces between them allow for the flow of water and mud. The curved first strip-shaped light-absorbing element further guides this flow, preventing corrosion and obstruction caused by impurities. This not only improves the tire's self-cleaning performance but also ensures a good visual presentation of the tread pattern. Attached Figure Description

[0044] To address the problem that the appearance of the tread pattern on the outer surface of tires in the prior art is not well improved, this application provides a tire.

[0045] Example 1

[0046] like Figures 1 to 7As shown, the tire has a surface 1, on which a tire tread structure protruding relative to the surface 1 is provided to form at least a portion of the outer surface of the tire. The tire tread structure includes a first strip light-absorbing element 10 and a light-absorbing assembly 20. The first strip light-absorbing element 10 is curved and arranged along a preset trajectory to form a marking pattern 30. The portion of the surface 1 where the first strip light-absorbing element 10 is not provided forms a filling surface 101. The light-absorbing assembly 20 is provided on the filling surface 101, and the first strip light-absorbing element 10 is inserted into the light-absorbing assembly 20. The light-absorbing assembly 20 has a strip light-absorbing recess 21 communicating with the outside. There is a light-absorbing recess 40 communicating with the outside between the light-absorbing assembly 20 and the first strip light-absorbing element 10. The first strip light-absorbing element 10 and the light-absorbing recess 40 communicate to form a drainage path. Both the strip-shaped light-absorbing recess 21 and the light-absorbing recess 40 are used to reflect the light beam incident upon them. The strip-shaped light-absorbing recess 21 has a width-to-depth ratio C in its cross-section, which satisfies the following condition: 0.42 ≤ C ≤ 0.69. The strip-shaped light-absorbing recess 21 and the light-absorbing recess 40 are connected.

[0047] Using the technical solution of this embodiment, the tire has a layout surface 1, on which a tire tread structure protruding relative to the layout surface 1 is provided to form at least part of the outer surface of the tire. The first strip light-absorbing element 10 of the tire tread structure is curved and arranged along a preset trajectory to form an identification pattern 30. The part of the layout surface 1 without the first strip light-absorbing element 10 forms a filling surface 101. The light-absorbing component 20 is disposed on the filling surface 101. The first strip light-absorbing element 10 is inserted into the light-absorbing component 20. The light-absorbing component 20 has a strip light-absorbing recess 21 communicating with the outside. There is a light-absorbing recess 40 communicating with the outside between the light-absorbing component 20 and the first strip light-absorbing element 10. Both the strip light-absorbing recess 21 and the light-absorbing recess 40 are used to reflect the light beam incident therein. The strip light-absorbing recess 21 has a width-to-depth ratio C in its cross-section, and the width-to-depth ratio C satisfies: 0.42≤C≤0.69. In this embodiment, the strip-shaped light-absorbing recess 21 and the light-absorbing recess 40 are connected. Thus, in this embodiment, the first strip-shaped light-absorbing element 10 and the light-absorbing assembly 20, protruding from the arrangement surface 1, can reflect the light beam through the strip-shaped light-absorbing recess 21 and the light-absorbing recess 40 while forming the tire tread structure. For example, after the light beam enters the strip-shaped light-absorbing recess 21, the light beam can undergo multiple reflections within it due to the width-to-depth ratio of the strip-shaped light-absorbing recess 21, thereby reducing the inherent optical defects of the tire's outer surface. Specifically, on the one hand, the emission direction of the light beam after multiple reflections is more complex (approximately diffuse reflection), thus avoiding the strong directional reflection caused by the near-specular reflection characteristics of the tire's outer surface (where the light beam is reflected only once). This increases the contrast between the tire tread pattern and the tire's outer surface. On the other hand, during multiple reflections, the light beam is absorbed multiple times, resulting in a smaller intensity of the emitted beam. This reduces the brightness of the tire tread pattern, making it darker than the tire's outer surface and creating a strong contrast. The combined effect of these features creates a "light trapping effect," ensuring that the marking pattern 30 creates a significant visual effect on the tire's outer surface and that the corresponding marking information (such as decorative or brand effects) can be quickly captured by the user. This solves the problem of poor aesthetic enhancement of the tire tread pattern on the outer surface in existing technologies. Meanwhile, the first strip light-absorbing element 10 and the light-absorbing recess 40 are connected to form a drainage path, thereby enabling the flow of water and mud through the interconnected strip light-absorbing recess 21 and light-absorbing recess 40, and discharging the water and mud to the outside. The curved first strip light-absorbing element 10 can further achieve the guiding effect to avoid corrosion and obstruction caused by impurities. This not only improves the self-cleaning performance of the tire, but also further ensures that the tire tread structure has a good visual presentation effect.

[0048] In this embodiment, the tire tread pattern is provided on the sidewall of the tire.

[0049] It should be noted that tire tread patterns can also be set on the tire tread (such as the bottom wall of the tread grooves).

[0050] like Figures 1 to 3 As shown, the light-absorbing component 20 includes multiple second strip-shaped light-absorbing elements 22. The second strip-shaped light-absorbing elements 22 extend along a first preset direction, and the multiple second strip-shaped light-absorbing elements 22 are arranged along a second preset direction, forming an angle between the first preset direction and the second preset direction. Along the second preset direction, two adjacent second strip-shaped light-absorbing elements 22 surround each other to form a strip-shaped light-absorbing recess 21; or, two adjacent second strip-shaped light-absorbing elements 22 surround each other with the arrangement surface 1 to form a strip-shaped light-absorbing recess 21. Each second strip-shaped light-absorbing element 22 has a connecting recess 221, which connects two adjacent strip-shaped light-absorbing recesses 21. This arrangement not only makes the formation of the strip-shaped light-absorbing recesses 21 simpler, more flexible, and more diverse, but also enables further communication between the strip-shaped light-absorbing recesses 21 through the connecting recess 221, increasing the communication area and ensuring rapid flow of water and mud, further improving the tire's self-cleaning performance and the visual presentation of the tire tread structure.

[0051] In this embodiment, the arrangement surface 1 is a rectangular surface, the first preset direction is the width direction of the rectangular surface, the second preset direction is the length direction of the rectangular surface, and the first preset direction and the second preset direction are set perpendicular to each other.

[0052] It should be noted that, in order to facilitate the corresponding limitation of the size, the size parameters defined in this embodiment are actually the size of the planar unfolded view. When the tire tread structure is set on the side of the tire in this embodiment, it actually needs to be matched with the side shape of the tire, that is, the arrangement surface 1 presents a spatial curved surface structure.

[0053] like Figure 1 and Figure 3 As shown, the connecting recess 221 has a first inner sidewall and a second inner sidewall disposed opposite to each other. The first inner sidewalls of any two connecting recesses 221 are separated by a distance L1, which satisfies the condition: 3mm ≤ L1 ≤ 33mm. This arrangement avoids an excessively dense arrangement of the connecting recesses 221, thus preventing difficulties in mold forming and stress concentration caused by excessive structural density, thereby improving the stability of the vulcanization process and product consistency.

[0054] Specifically, the above settings ensure uniform venting of the textured structure in the mold, reduce the risk of residual air bubbles, and improve the yield rate. On the other hand, they avoid structural interference and local stress concentration caused by too small a distance L1, which helps maintain the long-term stability and functionality of the textured structure (extending its service life).

[0055] In this embodiment, along the extending direction of the first strip light-absorbing element 10, the first strip light-absorbing element 10 has a segmented structure, that is, the first inner sidewall and the second inner sidewall are the end faces of the two first strip light-absorbing elements 10 respectively, and the bottom wall of the connecting recess 221 is the arrangement surface 1, so as to form a connecting recess 221 that is perpendicular to each other between the inner sidewall and the bottom wall, thereby making the visual presentation effect at the connecting recess 221 different from the visual presentation effect of the subsequent strip light-absorbing recess 21 (different in cross-sectional structure), further improving the overall visual presentation effect of the tire tread structure.

[0056] It should be noted that a notch can also be machined directly on the first strip light-absorbing element 10 to form the connecting recess 221.

[0057] like Figure 4 As shown, along the direction away from the arrangement surface 1, the width of at least part of the second strip light-absorbing member 22 gradually decreases, so as to form a first inclined surface 222 and a second inclined surface 223 on the outer surface of the second strip light-absorbing member 22. The first inclined surface 222 and the second inclined surface 223 are arranged opposite to each other, and both the first inclined surface 222 and the second inclined surface 223 are used to surround and form the strip light-absorbing recess 21. In this way, the above arrangement makes both inner sidewalls of the strip light-absorbing recess 21 have inclined surfaces, so as to further increase the number of reflections of the light beam inside it, enhance the "light trapping effect", and ensure that the marking pattern 30 is darker and has a stronger contrast compared to the side of the tire.

[0058] like Figure 4 As shown, along the second preset direction, two adjacent second strip-shaped light-absorbing elements 22 surround the arrangement surface 1 to form a strip-shaped light-absorbing recess 21, and the arrangement surface 1 forms the bottom wall of the strip-shaped light-absorbing recess 21. The maximum width W1 of the strip-shaped light-absorbing recess 21 satisfies: 0.15mm ≤ W1 ≤ 0.45mm, and the minimum width W2 of the strip-shaped light-absorbing recess 21 satisfies: 0.03mm ≤ W2 ≤ 0.15mm. The second strip-shaped light-absorbing element 22 has a maximum width W3, which satisfies: 0.15mm ≤ W3 ≤ 0.45mm. Thus, the above-mentioned dimensional settings further enhance the "light trap effect" of the strip-shaped light-absorbing recess 21 while simultaneously creating a fine textured structure on the surface 101 to be filled by multiple second strip-shaped light-absorbing elements 22, thereby further reducing the brightness value of the tire tread structure and improving the contrast at the tire tread structure. Meanwhile, the above-mentioned configuration not only helps to ensure the high structural strength of the second strip light-absorbing element 22, thus extending the service life of the texture structure, but also ensures that the second strip light-absorbing element 22 can squeeze out the liquid and mud located in the strip light-absorbing recess 21 during the tire rolling deformation process, further improving the self-cleaning effect of the tire tread structure.

[0059] Specifically, the fine texture can also produce light and shadow effects, further enhancing the overall visual presentation of the tire tread structure.

[0060] In this embodiment, the maximum width W1 is 0.3 mm, the minimum width W2 of the strip light-absorbing recess 21 is 0.03 mm, and the maximum width W3 of the second strip light-absorbing element 22 is 0.27 mm.

[0061] Optionally, the height H of the second strip light-absorbing element 22 (the depth of the strip light-absorbing recess 21) satisfies: 0.35mm≤H≤0.65mm.

[0062] In this embodiment, the height H of the second strip light-absorbing element 22 is 0.5mm, that is, the width-to-depth ratio C in this embodiment is approximately 3:5.

[0063] Specifically, since the cross-section of the strip-shaped light-absorbing recess 21 is an irregular shape with a gradually changing width, the width-to-depth ratio C in this embodiment is the ratio between the maximum width W3 and the height H (depth of the strip-shaped light-absorbing recess 21).

[0064] like Figure 4 As shown, both the first inclined surface 222 and the second inclined surface 223 are curved surfaces. The outer peripheral surface of the second strip-shaped light-absorbing element 22 also includes a first arc-shaped surface 224 located between the first inclined surface 222 and the second inclined surface 223. The first inclined surface 222 is connected to the second inclined surface 223 through the first arc-shaped surface 224. The end of the first inclined surface 222 away from the first arc-shaped surface 224 is connected to the arrangement surface 1, and the end of the second inclined surface 223 away from the first arc-shaped surface 224 is connected to the arrangement surface 1. Thus, with the arrangement surface 1 as the reference surface, the outer surface of the second strip-shaped light-absorbing element 22 is wider in the middle and gradually tapers to a rounded shape at the top. This design increases the chance of light reflecting multiple times within the texture, lengthens the light propagation path, and thus enhances the light trapping effect.

[0065] Specifically, the design of the second strip-shaped light-absorbing element 22 in this embodiment is actually based on the biomimetic design of the leaf contour of Lauraceae plants. The resulting cross-sectional structure is more prone to multiple reflections compared to the cross-section of a common isosceles triangle or a completely smooth tire side surface. This avoids the stress concentration problem common in traditional isosceles triangle structures, significantly delays crack propagation, enhances the tire's fatigue resistance, and extends its service life. In addition, the rounded top design reduces sharp edges and lowers the risk of wear caused by external friction.

[0066] Specifically, by mimicking the contour structure of biological leaves in nature that have efficient light absorption and drainage functions, the problem of lack of collaborative optimization mechanism in traditional tire sidewall texture design can be overcome, thereby achieving a four-dimensional synergistic improvement in "optics-mechanics-process-aesthetics".

[0067] In this embodiment, both the first inclined surface 222 and the second inclined surface 223 are arc-shaped surfaces. The diameter of the circle corresponding to the arc of their cross-section is approximately 22.4 mm, and the arc length is 4.3 mm.

[0068] In this embodiment, there is a certain gap between two adjacent second strip light-absorbing elements 22 (the minimum width W2 of the strip light-absorbing recess 21 is 0.03mm) so that the bottom wall of the strip light-absorbing recess 21 is formed by the arrangement surface 1.

[0069] In this embodiment, while defining the cross-sectional shape of the second strip light-absorbing element 22, the cross-section of the strip light-absorbing recess 21 is also made to have an open trumpet-shaped structure, which is conducive to drainage and mud discharge, reduces pollutant retention, and improves self-cleaning ability.

[0070] It should be noted that two adjacent second strip light-absorbing elements 22 can also be attached to each other, that is, the strip light-absorbing recess 21 is formed by only two adjacent first strip light-absorbing elements 10.

[0071] In this embodiment, there are multiple light-absorbing recesses 40. Along the direction away from the arrangement surface 1, at least a portion of the width of the first strip-shaped light-absorbing member 10 gradually decreases to form a third inclined surface and a fourth inclined surface on the outer surface of the first strip-shaped light-absorbing member 10. The third inclined surface and the fourth inclined surface are arranged opposite to each other. Specifically, a light-absorbing recess 40 is formed between the third inclined surface and the end face of the second strip-shaped light-absorbing member 22 located on one side of the first strip-shaped light-absorbing member 10 and the arrangement surface 1; or, a light-absorbing recess 40 is formed between the third inclined surface and the end face of the second strip-shaped light-absorbing member 22 located on one side of the first strip-shaped light-absorbing member 10. Another light-absorbing recess 40 is formed between the fourth inclined surface and the end face of the second strip-shaped light-absorbing member 22 located on the other side of the first strip-shaped light-absorbing member 10 and the arrangement surface 1; or, another light-absorbing recess 40 is formed between the fourth inclined surface and the end face of the second strip-shaped light-absorbing member 22 located on the other side of the first strip-shaped light-absorbing member 10. In this way, the above-mentioned arrangement also makes the inner wall of the light-absorbing recess 40 have an inclined surface, which helps to increase the number of reflections of the light beam within the light-absorbing recess 40 and enhance the light trapping effect. At the same time, the above-mentioned arrangement also makes the formation of the light-absorbing recess 40 more flexible and diverse, so as to adapt to different working conditions and usage requirements.

[0072] In this embodiment, a light-absorbing recess 40 is formed between the third inclined surface and the end face of the second strip light-absorbing member 22 located on one side of the first strip light-absorbing member 10, and another light-absorbing recess 40 is formed between the fourth inclined surface and the end face of the second strip light-absorbing member 22 located on the other side of the first strip light-absorbing member 10. That is, the end face of the second strip light-absorbing member 22 is in contact with the outer peripheral surface of the first strip light-absorbing member 10.

[0073] It should be noted that a certain gap is also provided between the end face of the second strip light absorber 22 and the outer peripheral surface of the first strip light absorber 10, so that a light-absorbing recess 40 is formed between the third inclined surface and the end face and arrangement surface 1 of the second strip light absorber 22 located on one side of the first strip light absorber 10, and another light-absorbing recess 40 is formed between the fourth inclined surface and the end face and arrangement surface 1 of the second strip light absorber 22 located on the other side of the first strip light absorber 10.

[0074] Optionally, both the third and fourth inclined surfaces are curved surfaces. The outer peripheral surface of the first strip light-absorbing element 10 also includes a third arcuate surface located between the third and fourth inclined surfaces. The third inclined surface is connected to the fourth inclined surface via the third arcuate surface. The end of the third inclined surface away from the third arcuate surface is connected to the arrangement surface 1, and the end of the fourth inclined surface away from the third arcuate surface is connected to the arrangement surface 1. Alternatively, both the third and fourth inclined surfaces are curved surfaces. The outer peripheral surface of the first strip light-absorbing element 10 also includes a fourth arcuate surface, a third plane, and a fourth plane. The fourth arcuate surface is located between the third and fourth inclined surfaces. The third inclined surface is connected to the fourth inclined surface via the fourth arcuate surface. The third inclined surface is connected to the arrangement surface 1 via the third plane, and the fourth inclined surface is connected to the arrangement surface 1 via the fourth plane. The third and fourth planes are arranged opposite each other, and the distance between the third and fourth planes gradually decreases along the direction away from the arrangement surface 1. In this way, the above arrangement makes the cross-sectional structure design of the first strip light-absorbing element 10 more flexible and diverse, so as to adapt to different working conditions and usage requirements.

[0075] In this embodiment, the cross-sectional design of the first strip light-absorbing element 10 is consistent with the cross-sectional design of the second strip light-absorbing element 22, that is, it also adopts the corresponding biomimetic structure.

[0076] It should be noted that the maximum width of the first strip light-absorbing element 10 is smaller than the maximum width of the second strip light-absorbing element 22, so that the visual effect presented by the first strip light-absorbing element 10 can be distinguished from that of the second strip light-absorbing element 22, ensuring that the logo pattern 30 is more prominent.

[0077] In this embodiment, the maximum width of the first strip light-absorbing element 10 is 0.18 mm.

[0078] It should be noted that this application also provides two additional cross-sectional designs for the second strip light-absorbing element 22 (Embodiment 2 and Embodiment 3). The cross-sectional design of the first strip light-absorbing element 10 can also adopt the designs in Embodiment 2 and Embodiment 3. That is, the combination of the first strip light-absorbing element 10 and the second strip light-absorbing element 22 can produce nine different cross-sectional design methods.

[0079] Specifically, the first strip light-absorbing element 10, which has the same cross-sectional design as the second strip light-absorbing element 22, also forms a textured structure, constituting a three-dimensional interlaced structure of "straight convex patterns + arc intervals", which makes the overall visual presentation effect of the tire tread structure better, overcomes the problem of insufficient visual layering of the smooth tire sidewall under different lighting angles, and thus enhances the human eye's sensitivity to brand logo recognition and the reliability of identification.

[0080] like Figure 5 As shown, this embodiment also provides a way of arranging the marking pattern 30 for the first strip light-absorbing element 10 and the light-absorbing component 20 with the above-described structural design, so as to ensure that the internal structure of the tire tread can present a sufficiently good visual presentation effect.

[0081] Optionally, multiple first strip light-absorbing elements 10 are arranged in an arc shape. Each first strip light-absorbing element 10 includes a first pattern forming element 11. The marking pattern 30 includes sub-patterns 31. Sub-patterns 31, when combined with sub-patterns 31 after translation and / or symmetry and / or rotation, form at least a portion of the marking pattern 30. Each sub-pattern 31 includes N1 first pattern forming elements 11. The number N1 of first pattern forming elements 11 is related to the dimension of the arrangement surface 1 along a first preset direction or a second preset direction. The radius R of the circle corresponding to each first pattern forming element 11 is different, and the radius R satisfies: R = N²·SR; where SR is a preset parameter value, N² = 1, 2, 3…N, and N is a positive integer. The central angle A corresponding to the first pattern forming element 11 satisfies: 90° ≤ A ≤ 180°.

[0082] like Figure 5 As shown, the plurality of first strip light-absorbing elements 10 also include second pattern forming elements 12, and the sub-pattern 31 further includes a plurality of first arc segments 32. The plurality of first arc segments 32 are arranged concentrically, and the radii of the circles corresponding to each first arc segment 32 are different. After being symmetrical along a preset axis of symmetry, the plurality of first arc segments 32 overlap with each other with N1 first pattern forming elements 11. Among them, at least one first arc segment 32 is formed by at least two second pattern forming elements 12 spaced apart. In the first arc segment 32, the gap between two adjacent second pattern forming elements 12 forms an avoidance notch 33, which is used to avoid the first pattern forming elements 11.

[0083] like Figure 5 As shown, there are eight sub-patterns 31 in total. Each sub-pattern 31 is first translated three times along the length of the rectangular arrangement surface 1 to obtain four sub-patterns 31. Then, it is translated once along the width of the rectangular arrangement surface 1 to obtain the identification pattern 30.

[0084] Specifically, the shape of the arrangement surface 1 corresponding to a sub-pattern 31 is a square, and there are five first pattern forming members 11. The five first pattern forming members 11 are arranged concentrically with a vertex of the square arrangement surface 1 as the center, and the vertex opposite to that vertex is the arrangement center of the first circular arc segment 32.

[0085] In this embodiment, the preset parameter value SR is 3mm, and the side length of the square arrangement surface 1 is 15mm, so five first strip light-absorbing elements 10 are set.

[0086] In this embodiment, the central angle A corresponding to the first pattern forming element 11 is 90°.

[0087] In this embodiment, there are five first arc segments 32. The five concentrically arranged first arc segments 32 are symmetrical about the diagonal of the square arrangement surface 1 and can coincide with the five first pattern forming elements 11. That is, the radius of the circle corresponding to the five first arc segments 32 is set to correspond one-to-one with the radius of the circle corresponding to the five first strip light-absorbing elements 10 (equal).

[0088] In this embodiment, the clearance notch 33 is used to allow the first pattern forming member 11 to pass through the first arc segment 32. The number of second pattern forming members 12 in the first arc segment 32 and the spacing between two adjacent second pattern forming members 12 can be adjusted accordingly based on the structural dimensions of the first pattern forming member 11.

[0089] In this embodiment, due to the aforementioned size limitation, there is a large overlapping area between the first arc segment 32 and the first pattern forming member 11. Therefore, a large clearance notch 33 is provided at the top circle of the first arc segment 32.

[0090] Optionally, the end of the second pattern forming member 12 located within the larger clearance notch 33 has a preset gap with the first pattern forming member 11, and the minimum value L2 of the preset gap satisfies: 0.3mm≤L2.

[0091] Specifically, the aforementioned interlacing design enables further diversion and circulation of liquids and slurries, which helps to improve the self-cleaning effect of the tire tread structure.

[0092] Specifically, by setting key parameters such as the number of central angles A and N1, the radius R, and the position of the center, the problem of application adaptability limited by a single structural form can be overcome, thereby enhancing the energy absorption capacity, drainage efficiency, and air vibration suppression function of the textured structure. Figure 5 The marking pattern formed by this multi-layered curved structure not only improves the mechanical cushioning performance of the tire sidewall and reduces the risk of cracking, but also regulates airflow through curvature changes, suppresses the noise and vibration generated by the tire tread structure on the tire sidewall when the tire rotates at high speed, and improves driving comfort.

[0093] like Figure 6 and Figure 7 As shown, Figure 1 (50) shows a side view of a conventional tire, and Figure 2 (60) shows a side view of a tire with the tread pattern structure described in Embodiment 1. Laboratory rubber blackness testing (CIE Lab color mode) was conducted on the visual presentation of these objects, and the following test results were obtained, as shown in Table 1:

[0094] Table 1

[0095]

[0096] Specifically, the Lab pattern uses L (Brightness / Darkness), a (Red-Green axis) and b The color characteristics are described using three dimensions: yellow and blue axes. This embodiment focuses on measuring L. The Lab color mode, which measures the brightness and darkness of the tire sidewall, better reflects the human eye's true perception of color compared to traditional optical density or grayscale detection methods. It avoids errors caused by factors such as light source and viewing angle, and its device independence facilitates data comparison and standardized management between different instruments. Therefore, the Lab color mode offers higher accuracy and practicality in the quality control of blackness in rubber products.

[0097] Specifically, as can be seen from the data in the table, the sidewall brightness value of Example 1 is reduced by 1.43 (dL) compared to conventional tires. This effectively reduces the brightness value of the tire tread pattern, making it darker and creating a more obvious contrast with the tire sidewall without a tread pattern, resulting in a more prominent marking pattern 30.

[0098] like Figure 8 As shown, the arrangement surface 1 is located on the sidewall of the tire and is arranged in a ring shape. The tire tread structure is arranged on the arrangement surface 1, and the second strip light-absorbing element 22 of the tire tread structure extends radially along the tire.

[0099] In this embodiment, the ring width B of the arrangement surface 1 is 15mm.

[0100] It should be noted that the value of the ring width B of the arrangement surface 1 is not limited and can be adjusted according to the actual ring width of the tire sidewall.

[0101] Specifically, Figure 8The black part in the diagram is the arrangement surface 1. The tire tread structure is set in the arrangement surface 1. While the tire tread structure has the marking pattern 30, the staff can also adjust the shape of the arrangement surface 1 so that the tire tread structure can further form the corresponding arrangement surface 1 pattern, which greatly improves the appearance of the tire.

[0102] Example 2

[0103] The difference between the tire in Example 2 and that in Example 1 is that the cross-sectional structure of the light-absorbing component 20 of the tire tread structure is different.

[0104] like Figure 9 As shown, both the first inclined surface 222 and the second inclined surface 223 are curved surfaces. The outer peripheral surface of the second strip light-absorbing element 22 also includes a first arc-shaped surface 224 located between the first inclined surface 222 and the second inclined surface 223. The first inclined surface 222 is connected to the second inclined surface 223 through the first arc-shaped surface 224. One end of the first inclined surface 222 away from the first arc-shaped surface 224 is connected to the arrangement surface 1, and one end of the second inclined surface 223 away from the first arc-shaped surface 224 is connected to the arrangement surface 1.

[0105] Specifically, in this embodiment, both the first inclined surface 222 and the second inclined surface 223 are arc-shaped surfaces. The diameter of the circle corresponding to the arc of the cross section of the two surfaces is larger than that of the circle corresponding to the arc of the cross section of the first inclined surface 222 and the second inclined surface 223 in Embodiment 1. That is, the first inclined surface 222 and the second inclined surface 223 in this embodiment are more prominent and resemble ellipses, while the cross section of the strip light-absorbing recess 21 presents a slightly constricted trumpet shape at the bottom.

[0106] Specifically, the design of the second strip-shaped light-absorbing element 22 in this embodiment is actually based on the biomimetic design of the leaf contour of Moringa plants in the Moringa genus of the Moringa family. The resulting elliptical cross-sectional structure is more likely to produce multiple reflections than a common isosceles triangle cross-section or a completely smooth tire side surface. This avoids the stress concentration problem common in traditional isosceles triangle structures, significantly delays crack propagation, enhances the tire's fatigue resistance, and extends its service life. In addition, the rounded top design reduces sharp edges and lowers the risk of wear caused by external friction.

[0107] Specifically, by mimicking the contour structure of biological leaves in nature that have efficient light absorption and drainage functions, the problem of lack of collaborative optimization mechanism in traditional tire sidewall texture design can be overcome, thereby achieving a four-dimensional synergistic improvement in "optics-mechanics-process-aesthetics".

[0108] Example 3

[0109] The tire in Example 3 differs from that in Example 1 in that the cross-sectional structure of the light-absorbing component 20 in the tire tread structure is different.

[0110] like Figure 10 As shown, both the first inclined surface 222 and the second inclined surface 223 are curved surfaces. The outer peripheral surface of the second strip light-absorbing element 22 also includes a second arc-shaped surface 225, a first plane 226 and a second plane 227. The second arc-shaped surface 225 is located between the first inclined surface 222 and the second inclined surface 223. The first inclined surface 222 is connected to the second inclined surface 223 through the second arc-shaped surface 225. The first inclined surface 222 is connected to the arrangement surface 1 through the first plane 226. The second inclined surface 223 is connected to the arrangement surface 1 through the second plane 227. The first plane 226 and the second plane 227 are arranged opposite to each other. Along the direction away from the arrangement surface 1, the distance between the first plane 226 and the second plane 227 gradually decreases.

[0111] Specifically, the design of the second strip-shaped light-absorbing element 22 in this embodiment is actually based on the biomimetic design of the leaf contour of the Araliaceae family's Schefflera genus. The resulting oval cross-sectional structure is more prone to multiple reflections compared to a common isosceles triangle cross-section or a completely smooth tire side surface. This avoids the stress concentration problem common in traditional isosceles triangle structures, significantly delays crack propagation, enhances the tire's fatigue resistance, and extends its service life. In addition, the rounded top design reduces sharp edges, lowering the risk of wear caused by external friction.

[0112] Specifically, by mimicking the contour structure of biological leaves in nature that have efficient light absorption and drainage functions, the problem of lack of collaborative optimization mechanism in traditional tire sidewall texture design can be overcome, thereby achieving a four-dimensional synergistic improvement in "optics-mechanics-process-aesthetics".

[0113] Example 4

[0114] The tire in Example 4 differs from that in Example 1 in that the arrangement and parameter settings of the marking pattern 30 are different.

[0115] like Figure 11 As shown, in this embodiment, the five first pattern forming members 11 of the logo pattern 30 in embodiment 1 are symmetrically arranged along the diagonal of the square arrangement surface 1. The five first pattern forming members 11 and the symmetrical five first pattern forming members 11 are combined to form a sub-pattern 31. Then, the sub-pattern 31 is translated once along the side length direction of the square arrangement surface 1 to obtain the logo pattern 30 in this embodiment.

[0116] Furthermore, in this embodiment, the preset parameter value SR was adjusted accordingly, so that the first pattern forming element 11 and the symmetrical first pattern forming element 11 do not have overlapping parts at the top circle, therefore, the following is not set. Figure 1 The larger clearance 33 is located at the top circle.

[0117] It should be noted that the specific dimensional parameters will not be elaborated here.

[0118] Example 5

[0119] The tire in Example 5 differs from that in Example 1 in that the arrangement and parameter settings of the marking pattern 30 are different.

[0120] like Figure 12 As shown, the identification pattern 30 provided in this embodiment is formed by the five first pattern forming members 11 of the identification pattern 30 in embodiment 1 to form a sub-pattern 31, and then the sub-pattern 31 is translated once along the side length direction of the square arrangement surface 1 to obtain the identification pattern 30 in this embodiment.

[0121] It should be noted that the specific dimensional parameters will not be elaborated here.

[0122] Example 6

[0123] The tire in Example 6 differs from that in Example 1 in that the arrangement and parameter settings of the marking pattern 30 are different.

[0124] like Figure 13 As shown, the preset parameter value SR in this embodiment is larger, so only two first pattern forming elements 11 are set. The two first pattern forming elements 11 are symmetrical along the diagonal of the square arrangement surface 1. The two first pattern forming elements 11 and the symmetrical two first pattern forming elements 11 are used to form a sub-pattern 31. Then the sub-pattern 31 is translated once along the side length direction of the square arrangement surface 1 to obtain the marking pattern 30 in this embodiment.

[0125] It should be noted that the specific dimensional parameters will not be elaborated here.

[0126] Example 7

[0127] The tire in Example 7 differs from that in Example 1 in that the arrangement of the marking pattern 30 is different.

[0128] like Figure 14 As shown, the identification pattern 30 provided in this embodiment is relatively large, and only a partial schematic diagram is provided. The actual identification pattern 30 has five first pattern forming elements 11. The five first pattern forming elements 11 form a sub-pattern 31. The sub-pattern 31 is rotated around the center point of the square arrangement surface 1. The identification pattern 30 is formed by the sub-pattern 31 and the rotated sub-pattern 31.

[0129] It should be noted that the specific dimensional parameters will not be elaborated here.

[0130] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0131] The tire has a surface with a tread pattern protruding from it to form at least part of the tire's outer surface. A first strip-shaped light-absorbing element of the tread pattern is curved and arranged along a predetermined trajectory to form a marking pattern. The portion of the surface without the first strip-shaped light-absorbing element forms a filling surface. A light-absorbing assembly is disposed on this filling surface. The first strip-shaped light-absorbing element is inserted within the light-absorbing assembly. The light-absorbing assembly has a strip-shaped light-absorbing recess communicating with the outside. A light-absorbing recess communicating with the outside is located between the light-absorbing assembly and the first strip-shaped light-absorbing element. Both the strip-shaped light-absorbing recess and the light-absorbing recess reflect light beams incident upon them. The strip-shaped light-absorbing recess has a width-to-depth ratio C in its cross-section, satisfying 0.42 ≤ C ≤ 0.69. The strip-shaped light-absorbing recesses are connected to each other. Thus, the first strip-shaped light-absorbing element and light-absorbing assembly protruding from the arrangement surface in this application, while forming the tire tread structure, can reflect the light beam through the strip-shaped light-absorbing recesses. For example, after the light beam enters the strip-shaped light-absorbing recess, the strip-shaped light-absorbing recess with the aforementioned width-to-depth ratio allows the light beam to undergo multiple reflections within it, thereby reducing the inherent optical defects of the tire's outer surface. Specifically, on the one hand, the emission direction of the light beam after multiple reflections is more complex (approximately diffuse reflection), thereby avoiding the strong directional reflection caused by the near-mirror reflection characteristics of the tire's outer surface (the light beam is only reflected once), and increasing the tire tread pattern. The contrast between the tread pattern and the tire's outer surface is enhanced. Furthermore, during multiple reflections, the light beam is absorbed multiple times, resulting in a lower intensity of the emitted beam. This reduces the brightness of the tread pattern, making it darker than the tire's outer surface, creating a strong contrast. This comprehensive design produces a "light trapping effect," ensuring the markings have a significant visual impact on the tire's outer surface and that the corresponding information (such as decorative or branding effects) is quickly captured by the user. This solves the problem of poor aesthetic enhancement of the tread pattern in existing technologies. Simultaneously, the interconnected strip-shaped light-absorbing recesses and the spaces between them allow for the flow of water and mud. The curved first strip-shaped light-absorbing element further guides this flow, preventing corrosion and obstruction caused by impurities. This not only improves the tire's self-cleaning performance but also ensures a good visual presentation of the tread pattern.
