Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tires, in particular to a tire. BACKGROUND

[0002] At present, as one of the components exposed to the outside world, the tire has the most important point of decorating the vehicle to improve the appearance of the vehicle in addition to the conventional driving ability. In the prior art, the tire side or the tread is usually designed with a pattern structure according to the corresponding brand and vehicle type to reflect the brand effect and the appearance characteristics of the corresponding type of vehicle.

[0003] However, the tire is usually black, although the pattern structure is arranged on the outer surface, the overall outer surface (especially the tire side) still adopts a smooth surface design, and the inherent defects of the optical properties will result in poor visual observation of the corresponding pattern structure, and the main inherent defects are as follows:

[0004] The smooth black surface has high mirror reflection characteristics on the one hand, and is easy to form strong directional reflection (and the reflection times are only once) under the light condition, thereby causing the imbalance of the incident light intensity and the mark area (the pattern arrangement area), and on the other hand, the reflectivity of the incident light is too high, thereby causing the large difference between the brightness value of the mark area (the pattern arrangement area) and the background area (the outer surface of the tire without the pattern structure) and the pure black reference value (in other words, the black is not black in the eyes due to the above inherent defects), and the brightness difference ΔL between the two is close to zero, which significantly weakens the optical contrast of the mark information, and easily causes misreading or recognition delay.

For example, the strip-shaped light-absorbing recess with the above width-depth ratio enables the light beams to be reflected multiple times inside the strip-shaped light-absorbing recess, so as to weaken the inherent optical defects of the outer surface of the tire. Specifically, on the one hand, the emission direction of the light beams after multiple reflections is more complex (approximately diffuse reflection), thereby avoiding the strong directional reflection caused by the approximately mirror reflection characteristics (the light beams are reflected only once) of the outer surface of the tire, and increasing the contrast between the tire pattern structure and the outer surface of the tire. On the other hand, the light beams are absorbed multiple times in the process of multiple reflections, that is, the light intensity of the emitted light beams is smaller, which can reduce the lightness value of the tire pattern structure, so that the tire pattern structure is darker than the outer surface of the tire, forming a strong contrast. The above settings comprehensively produce a "light trap effect", ensuring that the identification pattern can form a significant visual effect on the outer surface of the tire, and ensuring that the identification information (such as a decorative effect or a brand effect) corresponding to the identification pattern can be quickly captured by a user, thereby solving the problem of poor appearance aesthetic improvement effect of the pattern structure on the outer surface of the tire in the prior art. At the same time, the strip-shaped light-absorbing recess and the light-absorbing recess communicating with each other can realize the flow of water and mud, and the curve-shaped first strip-shaped light-absorbing part can further realize a flow guiding effect, so as to avoid the corrosion and shielding problems caused by the retention of impurities, thereby improving the self-cleaning performance of the tire and further ensuring that the tire pattern structure has a good visual presentation effect.

[0045] Embodiment one

[0046] As Figures 1 to 7As shown, the tire has a layout surface 1, the layout surface 1 is provided with a tire pattern structure protruding relative to the layout surface 1 for forming at least part of the outer surface of the tire, the tire pattern structure comprises a first strip-shaped light-absorbing member 10 and a light-absorbing assembly 20, the first strip-shaped light-absorbing member 10 is arranged in a curved shape, and the first strip-shaped light-absorbing member 10 is arranged along a preset track to form an identification pattern 30. The part of the layout surface 1 without the first strip-shaped light-absorbing member 10 forms a to-be-filled surface 101; the light-absorbing assembly 20 is arranged on the to-be-filled surface 101, the first strip-shaped light-absorbing member 10 is inserted into the light-absorbing assembly 20, the light-absorbing assembly 20 has a strip-shaped light-absorbing recess 21 in communication with the outside, and the light-absorbing assembly 20 and the first strip-shaped light-absorbing member 10 have a light-absorbing recess 40 in communication with the outside, the first strip-shaped light-absorbing member 10 and the light-absorbing recess 40 are communicated to form a drainage flow path. The strip-shaped light-absorbing recess 21 and the light-absorbing recess 40 are both used for reflecting the light beams entering thereinto, the strip-shaped light-absorbing recess 21 has a width-depth ratio C in its cross section, and the width-depth ratio C satisfies: 0.42≤C≤0.69. Wherein, the strip-shaped light-absorbing recess 21 is in communication with the light-absorbing recess 40.

[0047] The tire has a layout surface 1, the layout surface 1 is provided with a tire pattern structure protruding relative to the layout surface 1, and is used to form at least part of the outer surface of the tire. The first strip-shaped light-absorbing part 10 of the tire pattern structure is arranged in a curve shape and along a preset track to form an identification pattern 30. The part of the layout surface 1 without the first strip-shaped light-absorbing part 10 forms a to-be-filled surface 101. The light-absorbing assembly 20 is arranged on the to-be-filled surface 101, and the first strip-shaped light-absorbing part 10 penetrates into the light-absorbing assembly 20. The light-absorbing assembly 20 has a strip-shaped light-absorbing recess 21 in communication with the outside. The light-absorbing assembly 20 and the first strip-shaped light-absorbing part 10 have a light-absorbing recess 40 in communication with the outside. The strip-shaped light-absorbing recess 21 and the light-absorbing recess 40 are both used for reflecting the light beams entering thereinto. The strip-shaped light-absorbing recess 21 has a width-depth ratio C in its cross section, and the width-depth ratio C satisfies 0.42≤C≤0.69. The strip-shaped light-absorbing recess 21 is in communication with the light-absorbing recess 40. In this way, the first strip-shaped light-absorbing part 10 and the light-absorbing assembly 20 protruding from the layout surface 1 in the embodiment can reflect the light beams through the strip-shaped light-absorbing recess 21 and the light-absorbing recess 40 while forming the tire pattern structure. For example, after the light beams enter into the strip-shaped light-absorbing recess 21, the strip-shaped light-absorbing recess 21 with the above width-depth ratio can make the light beams reflect multiple times inside the strip-shaped light-absorbing recess 21, so as to weaken the inherent optical defects of the outer surface of the tire. Specifically, on the one hand, the emission direction of the light beams after multiple reflections is more complex (approximately diffuse reflection), thereby avoiding the strong directional reflection caused by the approximately mirror reflection characteristics (the light beams reflect only once) of the outer surface of the tire, and increasing the contrast between the tire pattern structure and the outer surface of the tire. On the other hand, the light beams are absorbed multiple times in the process of multiple reflections, that is, the light intensity of the emitted light beams is smaller, which can reduce the lightness value of the tire pattern structure, so that the tire pattern structure is darker than the outer surface of the tire, thereby forming a strong contrast. The above arrangement comprehensively produces a "light trap effect", ensures that the identification pattern 30 can form a significant visual effect on the outer surface of the tire, and ensures that the identification information (such as decoration effect or brand effect) corresponding to the identification pattern 30 can be quickly captured by the user, thereby solving the problem that the appearance aesthetic improvement effect of the pattern structure on the outer surface of the tire in the prior art is poor. Meanwhile, the first strip-shaped light-absorbing part 10 and the light-absorbing recess 40 are in communication to form a drainage flow path, thereby enabling the flow of water and mud between the strip-shaped light-absorbing recess 21 and the light-absorbing recess 40 in communication, and discharging the water and mud to the outside. The curve-shaped first strip-shaped light-absorbing part 10 can further realize a flow guiding effect, so as to avoid the corrosion and shielding problems caused by the retention of impurities, thereby not only improving the self-cleaning performance of the tire, but also further ensuring that the tire pattern structure has a good visual presentation effect.

[0048] In the embodiment, the tire pattern structure is arranged on the side surface of the tire.

[0049] It should be noted that the tire pattern structure can also be arranged on the tread of the tire (such as the tread groove bottom wall).

[0050] As shown in Figures 1 to 3 The light absorption assembly 20 includes a plurality of second strip-shaped light absorption members 22 extending along a first preset direction, and the plurality of second strip-shaped light absorption members 22 are arranged along a second preset direction, and the first preset direction and the second preset direction are arranged at an angle. Along the second preset direction, two adjacent second strip-shaped light absorption members 22 form a strip-shaped light absorption recess 21 therebetween, or two adjacent second strip-shaped light absorption members 22 and the arrangement surface 1 form a strip-shaped light absorption recess 21 therebetween. Among them, the second strip-shaped light absorption member 22 has a communication recess 221 for communicating two adjacent strip-shaped light absorption recesses 21. In this way, the above arrangement not only makes the formation of the strip-shaped light absorption recess 21 more simple, flexible, and diverse, but also enables further conduction between the strip-shaped light absorption recesses 21 through the communication recess 221, increases the communication area, ensures the rapid flow of water and mud, and further improves the self-cleaning performance of the tire and the visual presentation effect of the tire pattern 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, and the second preset direction is the length direction of the rectangular surface, and the first preset direction and the second preset direction are perpendicular to each other.

[0052] It should be noted that in order to facilitate the corresponding limitation of the size, the size parameter defined is actually the size of the planar development diagram. When the tire pattern structure in this embodiment is arranged on the side surface of the tire, it actually needs to be matched with the shape of the side surface of the tire, that is, the arrangement surface 1 presents a spatial curved surface structure.

[0053] As shown in Figure 1 and Figure 3 The communication recess 221 has a first inner side wall and a second inner side wall arranged opposite to each other. Among them, the distance L1 between the first inner side walls of any two communication recesses 221 satisfies: 3mm≤L1≤33mm. In this way, the above arrangement can avoid the setting density of the communication recess 221 being too dense to avoid the mold forming difficulty and stress concentration problem caused by the high structure density, thereby improving the stability of the vulcanization process and the consistency of the product.

[0054] Specifically, on the one hand, the above arrangement ensures the uniform exhaust performance of the texture structure in the mold, reduces the risk of bubble residue, and improves the yield; on the other hand, it avoids the structure interference and local stress concentration phenomenon caused by too small distance L1, which helps to maintain the long-term stability and functionality of the texture structure (extends the 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 that the second strip light-absorbing element 22 has high structural strength, 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 the embodiment, the first inclined surface 222 and the second inclined surface 223 are both arc surfaces, the diameters of the circles corresponding to the cross-sectional circular arcs of the two arc surfaces are about equal to 22.4 mm, and the arc lengths are 4.3 mm.

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

[0069] In the embodiment, the cross-sectional shape of the second strip-shaped light-absorbing member 22 is defined, and at the same time, the cross section of the strip-shaped light-absorbing recess 21 is designed to have an open horn structure, so as to facilitate drainage and dirt discharge, reduce the retention of pollutants, and improve the self-cleaning ability.

[0070] It should be noted that the two adjacent second strip-shaped light-absorbing members 22 can also be in close contact with each other, that is, the strip-shaped light-absorbing recess 21 is formed only by the two adjacent first strip-shaped light-absorbing members 10.

[0071] In the embodiment, the light-absorbing recess 40 is multiple, and the width of at least part of the first strip-shaped light-absorbing member 10 gradually decreases in the direction away from the arrangement surface 1, so as to form a third inclined surface and a fourth inclined surface on the outer surface of the first strip-shaped light-absorbing member 10, and the third inclined surface and the fourth inclined surface are oppositely arranged. The third inclined surface and the end surface 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 together form one light-absorbing recess 40, or the third inclined surface and the end surface of the second strip-shaped light-absorbing member 22 located on one side of the first strip-shaped light-absorbing member 10 together form one light-absorbing recess 40. The fourth inclined surface and the end surface 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 together form another light-absorbing recess 40, or the fourth inclined surface and the end surface of the second strip-shaped light-absorbing member 22 located on the other side of the first strip-shaped light-absorbing member 10 together form another light-absorbing recess 40. In this way, the above arrangement makes the inner wall of the light-absorbing recess 40 also have an inclined surface, which helps to increase the reflection times of the light beam in the light-absorbing recess 40 and improve the light trapping effect. At the same time, the above arrangement also makes the forming mode of the light-absorbing recess 40 more flexible and diverse, so as to adapt to different working conditions and use requirements.

[0072] In the embodiment, the third inclined surface and the end surface of the second strip-shaped light-absorbing member 22 located on one side of the first strip-shaped light-absorbing member 10 together form one light-absorbing recess 40, and the fourth inclined surface and the end surface of the second strip-shaped light-absorbing member 22 located on the other side of the first strip-shaped light-absorbing member 10 together form another light-absorbing recess 40, that is, the end surface of the second strip-shaped light-absorbing member 22 and the outer peripheral surface of the first strip-shaped light-absorbing member 10 are in close contact with each other.

[0073] It should be noted that a certain gap is also provided between the end face of the second strip-shaped light-absorbing member 22 and the outer peripheral surface of the first strip-shaped light-absorbing member 10, so that 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 together surround a light-absorbing recess 40, and 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 together surround another light-absorbing recess 40.

[0074] Optionally, the third inclined surface and the fourth inclined surface are both curved surfaces, and the outer peripheral surface of the first strip-shaped light-absorbing member 10 further comprises a third arc-shaped surface located between the third inclined surface and the fourth inclined surface, the third inclined surface is connected to the fourth inclined surface through the third arc-shaped surface, and one end of the third inclined surface away from the third arc-shaped surface is connected to the arrangement surface 1, and one end of the fourth inclined surface away from the third arc-shaped surface is connected to the arrangement surface 1. Optionally, the third inclined surface and the fourth inclined surface are both curved surfaces, and the outer peripheral surface of the first strip-shaped light-absorbing member 10 further comprises a fourth arc-shaped surface, a third plane and a fourth plane, the fourth arc-shaped surface is located between the third inclined surface and the fourth inclined surface, the third inclined surface is connected to the fourth inclined surface through the fourth arc-shaped surface, the third inclined surface is connected to the arrangement surface 1 through the third plane, the fourth inclined surface is connected to the arrangement surface 1 through the fourth plane, and the third plane and the fourth plane are oppositely arranged, and the distance between the third plane and the fourth plane gradually decreases in a direction away from the arrangement surface 1. In this way, the above-mentioned design is actually more flexible and diverse in the cross-sectional structure design of the first strip-shaped light-absorbing member 10, so as to adapt to different working conditions and use requirements.

[0075] In the present embodiment, the cross-sectional design of the first strip-shaped light-absorbing member 10 is consistent with the cross-sectional design of the second strip-shaped light-absorbing member 22, that is, the corresponding bionic structure is also adopted.

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

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

[0078] It should be noted that the present application additionally provides two kinds of cross-sectional designs (embodiment two and embodiment three) for the second strip-shaped light-absorbing member 22, and the cross-sectional design of the first strip-shaped light-absorbing member 10 can also adopt the design in embodiment two and embodiment three, that is, the mutual combination between the first strip-shaped light-absorbing member 10 and the second strip-shaped light-absorbing member 22 can produce nine different cross-sectional design modes.

[0079] Specifically, the first strip-shaped light-absorbing piece 10 consistent with the cross-sectional design of the second strip-shaped light-absorbing piece 22 actually also forms a textured structure, constituting a three-dimensional staggered structure of "straight-line convex + arc-line interval", so that the overall visual presentation effect of the tire pattern structure is more excellent, overcoming the problem of insufficient visual hierarchy of the smooth tire side under different light angles, thereby enhancing the identification sensitivity and reliability of the human eye to the brand logo.

[0080] As shown in Figure 5 , the embodiment also provides an arrangement manner of the logo pattern 30 for the first strip-shaped light-absorbing piece 10 and the light-absorbing assembly 20 adopting the above structure design, so as to ensure that the tire pattern structure can present a sufficiently excellent visual presentation effect.

[0081] Optionally, the first strip-shaped light-absorbing piece 10 is arranged in an arc shape and is a plurality of first strip-shaped light-absorbing pieces 10, the plurality of first strip-shaped light-absorbing pieces 10 include the first pattern forming piece 11, the logo pattern 30 includes a sub-pattern 31, the sub-pattern 31 and the sub-pattern 31 after translation and / or symmetry and / or rotation combine to form at least part of the logo pattern 30, the sub-pattern 31 includes N1 first pattern forming pieces 11, the number N1 of the first pattern forming pieces 11 is related to the size of the arrangement surface 1 in the first preset direction or the second preset direction, the radius R of the circle corresponding to each first pattern forming piece 11 is different, and the radius R satisfies R=N2·SR; wherein SR is a preset parameter value, N2=1, 2, 3,..., N, and N is a positive integer. The central angle A of the circle corresponding to the first pattern forming piece 11 satisfies 90°≤A≤180°.

[0082] As shown in Figure 5 , the plurality of first strip-shaped light-absorbing pieces 10 further include a second pattern forming piece 12, and the sub-pattern 31 further includes a plurality of first arc segments 32, the plurality of first arc segments 32 are concentrically arranged, the radius of the circle corresponding to each first arc segment 32 is different, and the plurality of first arc segments 32 are symmetrical along the preset symmetry axis and coincide with the N1 first pattern forming pieces 11. At least one first arc segment 32 is formed by being arranged at intervals by at least two second pattern forming pieces 12, and in the first arc segment 32, the gap between the adjacent two second pattern forming pieces 12 forms a relief gap 33 for avoiding the first pattern forming piece 11.

[0083] As shown in Figure 5 , the sub-pattern 31 is eight in total, one sub-pattern 31 is translated three times along the length direction of the rectangular arrangement surface 1 to obtain four sub-patterns 31, and then translated once along the width direction of the rectangular arrangement surface 1, so as to obtain the logo pattern 30.

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

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

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

[0087] In the embodiment, the first circular arc segment 32 is five, and the five concentrically arranged first circular arc segments 32 are symmetrical with respect to the diagonal of the square arrangement surface 1 as the axis of symmetry, that is, the radii of the circles corresponding to the five first circular arc segments 32 are arranged one by one (equal) with the radii of the circles corresponding to the five first strip-shaped light-absorbing members 10.

[0088] In the embodiment, the avoidance gap 33 is used for the first pattern forming member 11 to penetrate into the first circular arc segment 32, and the number of the second pattern forming members 12 arranged in the first circular arc segment 32 and the spacing between the two adjacent second pattern forming members 12 can be adjusted according to the structural size of the first pattern forming member 11.

[0089] In the embodiment, due to the above-mentioned size limitation, there is a large penetration overlap area between the first circular arc segment 32 and the first pattern forming member 11, so a large size avoidance gap 33 is arranged at the top circle of the first circular arc segment 32.

[0090] Optionally, the end of the second pattern forming member 12 located in the above-mentioned large size avoidance gap 33 has a preset gap with the first pattern forming member 11, and the minimum value L2 of the preset gap satisfies: 0.3 mm≤L2.

[0091] Specifically, the above-mentioned penetration design can realize further flow guide and circulation of liquid and slurry, which helps to improve the self-cleaning effect of the tire pattern structure.

[0092] Specifically, by setting the key parameters such as the central angle A, the number N1, the radius R, and the arrangement center position, the problem of application adaptability limited by single structure form can be overcome, and the energy absorption capacity, the drainage efficiency, and the air vibration suppression function of the texture structure are enhanced. Figure 5 The identification pattern formed by the multi-level curve structure not only improves the mechanical buffering performance of the sidewall and reduces the cracking risk, but also adjusts the air flow through the curvature change to suppress the noise vibration generated by the tire pattern structure on the sidewall when the tire rotates at high speed, and improves the driving comfort.

[0093] As shown in Figure 6 and Figure 7 , Figure 1 shows a side view of a conventional tire, and Figure 2 shows a side view of a tire provided with the tire pattern structure of Embodiment 1. After laboratory rubber blackness detection (CIE Lab color mode) is performed on the visual presentation of the above-mentioned figures, the following test results are obtained, as shown in Table 1:

[0094] Table 1

[0095]

[0096] Specifically, the Lab mode describes color characteristics through three dimensions of L (lightness), a (red-green axis), and b (yellow-blue axis). The focus of the present embodiment is to measure the L value, i.e., the lightness of the tire side. Compared with the conventional optical density or gray scale detection method, the Lab mode can better reflect the real perception of the human eye to color, avoid errors caused by factors such as light source and observation angle, and its device independence facilitates data comparison and standardized management between different instruments. Therefore, in the quality control of rubber product blackness, the Lab color mode has higher precision and practicality.

[0097] Specifically, from the data in the table, the lightness value of the tire side of Embodiment 1 is reduced by 1.43 (dL ) compared with the conventional tire, so that the lightness value at the tire pattern structure can be effectively reduced, darker, and the contrast between the tire side without the tire pattern structure is more obvious, and the presented identification pattern 30 is more prominent.

[0098] As shown in Figure 8 , the arrangement surface 1 is arranged on the tire side and is annularly arranged, and the tire pattern structure is arranged on the arrangement surface 1, and the second light-absorbing member 22 of the tire pattern structure extends along the radial direction of the tire.

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

[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 size of the tire side.

[0101] Specifically, Figure 8The black part in the figure is the arrangement surface 1, and the tire pattern structure is arranged in the arrangement surface 1. In addition to the identification pattern 30, the tire pattern structure can further form a corresponding arrangement surface 1 pattern by adjusting the shape of the arrangement surface 1, which greatly improves the appearance of the tire.

[0102] Embodiment two

[0103] The tire in embodiment two is different from that in embodiment one in that the cross-sectional structure of the light-absorbing component 20 of the tire pattern structure is different.

[0104] As shown in Figure 9 the first inclined surface 222 and the second inclined surface 223 are both curved surfaces. The outer peripheral surface of the second strip-shaped light-absorbing member 22 further comprises a first arc 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 surface 224. One end of the first inclined surface 222 away from the first arc surface 224 is connected to the arrangement surface 1. One end of the second inclined surface 223 away from the first arc surface 224 is connected to the arrangement surface 1.

[0105] Specifically, the first inclined surface 222 and the second inclined surface 223 in the embodiment are both arc surfaces, and the diameters of the circles corresponding to the cross-sectional circular arcs of the first inclined surface 222 and the second inclined surface 223 are larger than those in embodiment one. That is, the first inclined surface 222 and the second inclined surface 223 in the embodiment are more prominent and similar to an ellipse, and the cross section of the strip-shaped light-absorbing recess 21 is in the shape of a slightly tightened horn.

[0106] Specifically, the design of the second strip-shaped light-absorbing member 22 in the embodiment is actually a biomimetic design aiming at the leaf profile of the plant of the Moringa family. The elliptical cross-sectional structure formed is more likely to produce multiple reflections than the ordinary isosceles triangular cross section or the completely smooth tire side surface, avoiding the stress concentration problem commonly seen in traditional isosceles triangular structures, significantly slowing down crack propagation, enhancing the fatigue resistance of the tire, and prolonging the service life. In addition, the circular arc top design can reduce sharp edges and reduce the risk of wear caused by external friction.

[0107] Specifically, by imitating the leaf profile structure of organisms in nature that have high light absorption and drainage functions, the problem of lack of synergistic optimization mechanism in traditional tire side texture design can be overcome, thereby realizing four-dimensional synergistic improvement of "optics-mechanics-technology-aesthetics".

[0108] Embodiment three

[0109] The tire in embodiment three is different from that in embodiment one in that the cross-sectional structure of the light-absorbing component 20 of the tire pattern structure is different.

[0110] As Figure 10 shown, the first inclined surface 222 and the second inclined surface 223 are both curved surfaces, the outer peripheral surface of the second strip-shaped light-absorbing member 22 further comprises 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 with the second inclined surface 223 through the second arc-shaped surface 225, the first inclined surface 222 is connected with the arrangement surface 1 through the first plane 226, the second inclined surface 223 is connected with the arrangement surface 1 through the second plane 227, the first plane 226 and the second plane 227 are oppositely arranged, and the distance between the first plane 226 and the second plane 227 gradually decreases in the direction away from the arrangement surface 1.

[0111] Specifically, the design of the second strip-shaped light-absorbing member 22 in the embodiment is actually a biomimetic design aiming at the leaf profile of the plant of the Aralia genus in the family Araliaceae, and the formed oval-like cross-sectional structure is more likely to produce multiple reflections than the ordinary isosceles triangular cross-section or the completely smooth tire side surface, thereby avoiding the stress concentration problem commonly seen in the traditional isosceles triangular structure, significantly delaying crack propagation, enhancing the fatigue resistance of the tire, and prolonging the service life. In addition, the circular arc top design can reduce sharp edges and reduce the risk of wear caused by external friction.

[0112] Specifically, by imitating the leaf profile structure of organisms in nature that has high efficient light absorption and drainage function, the problem of lack of synergistic optimization mechanism in the traditional tire side texture design can be overcome, and four-dimensional synergistic improvement of "optics-mechanics-technology-aesthetics" can be realized.

[0113] Embodiment Four

[0114] The tire in Embodiment Four differs from that in Embodiment One in that the arrangement manner and parameter setting of the identification pattern 30 are different.

[0115] As Figure 11 shown, the identification pattern 30 provided in the embodiment first symmetrically arranges the five first pattern forming members 11 of the identification pattern 30 in Embodiment One along the diagonal lines of the square arrangement surface 1, forms a sub-pattern 31 by the five first pattern forming members 11 and the symmetrically arranged five first pattern forming members 11, and then translates the sub-pattern 31 along the length direction of the square arrangement surface 1 to obtain the identification pattern 30 in the embodiment.

[0116] In addition, the preset parameter value SR in the embodiment is adjusted accordingly, so that the first pattern forming members 11 and the symmetrically arranged first pattern forming members 11 do not have overlapping parts at the top circle, and therefore, the avoidance gap 33 with a large size at the top circle in Embodiment One is not provided. Figure 1 ​

[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 the present invention achieve the following technical effects:

[0131] The tire has an arrangement surface, a tire pattern structure is arranged on the arrangement surface and protrudes relative to the arrangement surface, and is used to form at least part of an outer surface of the tire, a first strip-shaped light-absorbing part of the tire pattern structure is arranged in a curved shape and along a preset track to form an identification pattern, a part of the arrangement surface on which the first strip-shaped light-absorbing part is not arranged forms a to-be-filled surface, a light-absorbing assembly is arranged on the to-be-filled surface, the first strip-shaped light-absorbing part is inserted in the light-absorbing assembly, the light-absorbing assembly has a strip-shaped light-absorbing recess that is in communication with the outside, and the light-absorbing assembly and the first strip-shaped light-absorbing part have a light-absorbing recess that is in communication with the outside, the strip-shaped light-absorbing recess and the light-absorbing recess are both used to reflect light beams that enter them, the strip-shaped light-absorbing recess has a width-depth ratio C in its cross section, and the width-depth ratio C satisfies: 0.42≤C≤0.69. The strip-shaped light-absorbing recess is in communication with the light-absorbing recess. In this way, the first strip-shaped light-absorbing part and the light-absorbing assembly that protrude from the arrangement surface in the present application can reflect light beams through the strip-shaped light-absorbing recess and the light-absorbing recess while forming the tire pattern structure, for example, after the light beams enter the strip-shaped light-absorbing recess, the strip-shaped light-absorbing recess with the above width-depth ratio is used to enable the light beams to be reflected multiple times inside the strip-shaped light-absorbing recess, so as to weaken the inherent optical defects of the outer surface of the tire. Specifically, on the one hand, the directions of the light beams after multiple reflections are more complex (approximately diffuse reflection), thereby avoiding the strong directional reflection caused by the approximately specular reflection characteristics (the light beams are reflected only once) of the outer surface of the tire, and increasing the contrast between the tire pattern structure and the outer surface of the tire; on the other hand, the light beams are absorbed multiple times in the process of multiple reflections, that is, the light intensity of the outgoing light beams is smaller, which can reduce the lightness value of the tire pattern structure, so that the tire pattern structure is darker than the outer surface of the tire, forming a strong contrast, the above arrangement comprehensively produces a "light trap effect", ensures that the identification pattern can form a significant visual effect on the outer surface of the tire, and ensures that the identification information (such as a decorative effect or a brand effect) corresponding to the identification pattern can be quickly captured by a user, thereby solving the problem that the appearance aesthetic improvement effect of the pattern structure on the outer surface of the tire in the prior art is poor. At the same time, the strip-shaped light-absorbing recess and the light-absorbing recess that are in communication with each other can realize the flow of water and mud, and the curvedly arranged first strip-shaped light-absorbing part can further realize a flow guiding effect, so as to avoid the corrosion and shielding problems caused by the retention of impurities, not only improving the self-cleaning performance of the tire, but also further ensuring that the tire pattern structure has a good visual presentation effect.
