Description

Technical Field

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

[0002] Currently, tires, as one of the key components of automobiles, directly contact the road surface and work with the vehicle's suspension to mitigate the impacts experienced during driving, ensuring good ride comfort and smooth driving. The design of the tire's sidewall, tread grooves, and groove bottom directly affects the vehicle's aerodynamic performance, noise performance, and the tire's visual visibility.

[0003] In existing technologies, manufacturers typically add trademarks, fonts, and decorative patterns to the outer surface of tires to enhance their aesthetics and recognizability.

[0004] However, the outer surface of tires is usually made of vulcanized black rubber material, which has a smooth surface and mirror-reflective properties. This makes the tire easy to produce a uniform gray reflection effect under light. The smooth surface cannot extend the incident path of light, resulting in excessive brightness. As a result, the trademarks, fonts and decorative patterns on the outer surface of the tire are difficult to clearly identify, and the visual contrast is low, which reduces the tire's recognizability and aesthetics. Summary of the Invention

[0005] The main objective of this invention is to provide a tire that solves the problem of poor recognizability and aesthetics in existing tires.

[0006] To achieve the above objectives, the present invention provides a tire, comprising: a main body structure having a marking area on its surface; and a light-absorbing unit disposed on the marking area. The light-absorbing unit includes a central component and a surrounding component. The central component has a first light-absorbing recess, and the surrounding component is sleeved on the central component. A plurality of second light-absorbing recesses are formed around the surrounding component and the central component. The plurality of second light-absorbing recesses are arranged sequentially along the circumference of the surrounding component. Both the first and second light-absorbing recesses are used to absorb external light. The cross-sectional area of ​​the first light-absorbing recess gradually decreases along the direction from the central component to the main body structure, and / or the cross-sectional area of ​​the second light-absorbing recess gradually decreases.

[0007] Furthermore, each of the second light-absorbing recesses has an inner wall, and the inner wall has an inner wall projection on the marking area; wherein, the shapes of the inner wall projections of at least two of the second light-absorbing recesses are different.

[0008] Furthermore, there are multiple light-absorbing units, which are divided into multiple groups. Each group of light-absorbing units includes multiple light-absorbing units. The multiple groups of light-absorbing units are arranged sequentially along a first preset direction, and the multiple light-absorbing units in each group are arranged sequentially along a second preset direction. The first preset direction and the second preset direction are set at an angle.

[0009] Furthermore, the enclosure component includes multiple enclosure structures connected in sequence. Each enclosure structure includes a first support portion and a first connecting portion. The first support portion is disposed on the marking area, and the first connecting portion is disposed on the first support portion. Along the direction from the first support portion to the first connecting portion, the cross-sectional area of ​​the first connecting portion gradually decreases, so that the first connecting portion has a first inclined surface and a second inclined surface. The height H1 of the first connecting portion satisfies: 0.2mm≤H1≤0.5mm, and the maximum distance L1 between the first inclined surface and the second inclined surface satisfies: 0.15mm≤L1≤0.35mm. And / or, the first inclined surface is set at a first angle A1 with the extension direction of the first support portion, and the first angle A1 satisfies: 60°≤A1≤80°. And / or, the second inclined surface is set at a second angle A2 with the extension direction of the first support portion, and the second angle A2 satisfies: 60°≤A2≤80°.

[0010] Furthermore, the central component includes a central structure and multiple branch structures, which are spaced apart circumferentially along the central structure. The central structure includes multiple central portions connected in sequence, which surround to form a first light-absorbing recess. A second light-absorbing recess is formed between the outer wall surfaces of the surrounding component, two adjacent branch structures, and the central portions.

[0011] Furthermore, the central portion includes a second supporting portion and a second connecting portion. The second supporting portion is disposed on the marking area, and the second connecting portion is disposed on the second supporting portion. Along the direction from the second supporting portion to the second connecting portion, the cross-sectional area of ​​the second connecting portion gradually decreases, so that the second connecting portion has a third inclined surface and a fourth inclined surface. Wherein, the height H2 of the second connecting portion satisfies: 0.2mm≤H2≤0.5mm, the maximum distance L2 between the third inclined surface and the fourth inclined surface satisfies: 0.15mm≤L2≤0.35mm; and / or, the third inclined surface is set at a third angle A3 with the extension direction of the second supporting portion, and the third angle A3 satisfies: 60°≤A3≤80°; and / or, the fourth inclined surface is set at a fourth angle A4 with the extension direction of the second supporting portion, and the fourth angle A4 satisfies: 60°≤A4≤80°.

[0012] Furthermore, the branch structure includes a third bearing portion and a third connecting portion. The third bearing portion is disposed on the marking area, and the third connecting portion is disposed on the third bearing portion. Along the direction from the third bearing portion to the third connecting portion, the cross-sectional area of ​​the third connecting portion gradually decreases, so that the third connecting portion has a fifth inclined surface and a sixth inclined surface. Wherein, the height H3 of the third connecting portion satisfies: 0.2mm≤H3≤0.5mm, the maximum distance L3 between the fifth inclined surface and the sixth inclined surface satisfies: 0.15mm≤L3≤0.35mm; and / or, the fifth inclined surface is set at a fifth angle A5 with the extension direction of the third bearing portion, and the fifth angle A5 satisfies: 60°≤A5≤80°; and / or, the sixth inclined surface is set at a sixth angle A6 with the extension direction of the third bearing portion, and the sixth angle A6 satisfies: 60°≤A6≤80°.

[0013] Furthermore, the end of the first light-absorbing recess furthest from the main structure has a first opening, and the maximum area S1 of the first opening satisfies: 0.03 mm. 2 ≤S1≤0.13mm 2 ; and / or, the first light-absorbing recess has a second opening at one end near the main structure, and the maximum area S2 of the second opening satisfies: 0.00071 mm. 2 ≤S2≤0.0177mm 2 ; and / or, the end of the second light-absorbing recess away from the main structure has a third opening, and the maximum area S3 of the third opening satisfies: 0.03 mm 2 ≤S3≤0.13mm 2 ; and / or, the second light-absorbing recess has a fourth opening at one end near the main structure, and the maximum area S4 of the fourth opening satisfies: 0.00071 mm 2 ≤S4≤0.0177mm 2 ; and / or, the projection of the enclosure component onto the marking area is a polygon, and the maximum area S5 of the polygon satisfies: 0.25mm. 2 ≤S5≤9mm 2 .

[0014] Furthermore, the enclosure structure is arranged in a zigzag shape, and the branch structure includes: a first branch member, which is arranged in a straight line or a zigzag shape, with one end of the first branch member connected to the central structure and the other end of the first branch member connected to the enclosure structure; and a second branch member, which includes a main branch and at least two secondary branches, with one end of the main branch connected to the central structure and the other end of the main branch connected to at least two secondary branches, and the end of the secondary branches away from the main branch connected to the enclosure structure.

[0015] Furthermore, the enclosure structure is arranged in a zigzag pattern, and the branch structure includes: a first branch member, one end of which is connected to the connection point of two adjacent central parts, and the other end of which is connected to the bend of the enclosure structure; a second branch member, including a main branch and at least two secondary branches, one end of which is connected to the connection point of two adjacent central parts, and the other end of which is connected to at least two secondary branches, and the end of the secondary branches away from the main branch is connected to the bend of the enclosure structure; wherein, the first branch member, the main branch, and the secondary branches are all arranged in a straight line.

[0016] Applying the technical solution of the present invention, the surface of the main structure of the tire has a marking area; a light-absorbing unit is disposed on the marking area, the light-absorbing unit includes a central component and a surrounding component, the central component has a first light-absorbing recess, the surrounding component is sleeved on the central component, and a plurality of second light-absorbing recesses are formed around the surrounding component and the central component, the plurality of second light-absorbing recesses are arranged sequentially along the circumference of the surrounding component, and both the first light-absorbing recess and the second light-absorbing recess are used to absorb external light; wherein, along the direction from the central component to the main structure, the cross-sectional area of ​​the first light-absorbing recess gradually decreases; and / or, the cross-sectional area of ​​the second light-absorbing recess gradually decreases. In this way, when external light shines on the tire, the inner walls of both the first and second light-absorbing recesses can reflect the light multiple times, causing light attenuation and reducing its brightness. This achieves the effect of absorbing and converting incident light, reducing the tire's specular reflection intensity, increasing its diffuse reflectivity, reducing visual differences in brightness, increasing the reflective area of ​​light, and weakening the intensity of light reflection. This results in a larger grayscale value in the marking area, making it appear darker and blacker under light, which is beneficial for consumer recognition. This improves the tire's recognizability and aesthetics, thus solving the problem of poor tire recognizability and aesthetics in existing technologies. Simultaneously, the arrangement of the first and second light-absorbing recesses also increases the roughness of the main structure, disrupting the stability of airflow during tire operation, disturbing the sound wave propagation path in the airflow, preventing the formation of regular sound wave superposition, suppressing the periodic compression and release of air in the tire grooves, reducing high-frequency noise generated by air column resonance, and dispersing the noise frequency to a frequency band insensitive to the human ear, thereby reducing the peak sound pressure level and lowering tire noise. At the same time, the above settings can also increase the contact area between the tire rubber and the mold during the vulcanization process, avoiding the situation where the tire cannot be degummed after vulcanization and the rubber sticks to the mold, thus reducing the cost of mold maintenance and cleaning.

[0039] To address the problem of poor recognizability and aesthetics of existing tires, this application provides a tire.

[0040] Example 1

[0041] like Figures 1 to 10As shown, the tire includes a main structure 10 and a light-absorbing unit 20. The surface of the main structure 10 has a marking area 11. The light-absorbing unit 20 is disposed on the marking area 11. The light-absorbing unit 20 includes a central component 30 and a surrounding component 40. The central component 30 has a first light-absorbing recess 50. The surrounding component 40 is sleeved on the central component 30, and a plurality of second light-absorbing recesses 60 are formed around the surrounding component 40 and the central component 30. The plurality of second light-absorbing recesses 60 are arranged sequentially along the circumference of the surrounding component 40. Both the first light-absorbing recess 50 and the second light-absorbing recesses 60 are used to absorb external light. Specifically, along the direction from the central component 30 to the main structure 10, the cross-sectional area of ​​the first light-absorbing recess 50 gradually decreases; and / or, the cross-sectional area of ​​the second light-absorbing recesses 60 gradually decreases.

[0042] Applying the technical solution of this embodiment, the surface of the main body structure 10 of the tire has a marking area 11; a light-absorbing unit 20 is disposed on the marking area 11. The light-absorbing unit 20 includes a central component 30 and a surrounding component 40. The central component 30 has a first light-absorbing recess 50. The surrounding component 40 is sleeved on the central component 30. A plurality of second light-absorbing recesses 60 are formed around the surrounding component 40 and the central component 30. The plurality of second light-absorbing recesses 60 are arranged sequentially along the circumference of the surrounding component 40. Both the first light-absorbing recess 50 and the second light-absorbing recesses 60 are used to absorb external light. In the direction from the central component 30 to the main body structure 10, the cross-sectional area of ​​the first light-absorbing recess 50 gradually decreases; and / or, the cross-sectional area of ​​the second light-absorbing recess 60 gradually decreases. In this way, when external light shines on the tire, the inner walls of the first light-absorbing recess 50 and the second light-absorbing recess 60 can reflect the light multiple times, causing the light to attenuate and weakening the brightness of the light. This achieves the effect of absorbing and converting the incident light, reducing the specular reflection intensity of the tire, increasing the diffuse reflection rate of the tire, reducing the visual difference between light and dark, increasing the light reflection area, and weakening the light reflection intensity. This makes the gray value of the marking area 11 larger, presenting a darker and blacker effect under light, which is beneficial to consumers' identification. This improves the tire's recognizability and aesthetics, thereby solving the problem of poor tire recognizability and aesthetics in the prior art. Meanwhile, the arrangement of the first light-absorbing recess 50 and the second light-absorbing recess 60 increases the roughness of the main structure 10, disrupting the stability of airflow during tire operation, interfering with the propagation path of sound waves in the airflow, preventing the formation of regular sound wave superposition, suppressing the periodic compression and release of air in the tire grooves, reducing high-frequency noise caused by air column resonance, dispersing the noise frequency to a frequency band insensitive to the human ear, thereby reducing the peak sound pressure level and lowering tire noise. Furthermore, the above arrangement also increases the contact area between the tire rubber and the mold during vulcanization, preventing the tire from failing to debond after vulcanization and the rubber from sticking to the mold, thus reducing the cost of mold maintenance and cleaning.

[0043] like Figure 1 As shown, the main structure 10 includes a tread and a sidewall, and the tread is provided with tread grooves.

[0044] Optionally, the light-absorbing unit 20 is disposed on the side wall of the patterned groove; and / or, the light-absorbing unit 20 is disposed on the bottom of the patterned groove.

[0045] Optionally, the light-absorbing unit 20 is disposed on the tire sidewall.

[0046] In this embodiment, the light-absorbing unit 20 is processed using laser engraving technology, ensuring the reliability of the processing. Simultaneously, the high-precision control of laser engraving enables the formation of uniform engraving textures in the marking area 11, preventing dust adhesion, improving the frictional stability of the marking area 11 when in contact with the external environment, enhancing the wear resistance of the marking area 11, reducing the breakage of rubber molecular chains caused by repeated deformation, thereby delaying the aging of the marking area 11, improving its fatigue resistance, and ultimately extending the tire's service life.

[0047] like Figures 2 to 4 As shown, each of the second light-absorbing recesses 60 has an inner wall, and the inner wall has a projection on the marking area 11; wherein, the shapes of the inner wall projections of at least two of the second light-absorbing recesses 60 are different. In this way, the above arrangement makes the shapes of the multiple second light-absorbing recesses 60 inconsistent, thereby making the second light-absorbing recesses 60 have irregular shapes, which in turn makes the light-absorbing unit 20 have complex and interwoven refraction paths, which can efficiently absorb and convert incident light and scatter light in multiple directions, realizing soft reflection of light, reducing visual differences in brightness and darkness, and improving the recognizability and aesthetics of the marking area 11.

[0048] In this embodiment, the inner wall projections of the multiple second light-absorbing recesses 60 are all different, and the inner wall projection of the first light-absorbing recess 50 is also different from the inner wall projection of any of the second light-absorbing recesses 60.

[0049] like Figure 10As shown, there are multiple light-absorbing units 20, which are divided into multiple groups. Each group of light-absorbing units 20 includes multiple light-absorbing units 20. The multiple groups of light-absorbing units 20 are arranged sequentially along a first preset direction, and the multiple light-absorbing units 20 in each group are arranged sequentially along a second preset direction. The first preset direction and the second preset direction are set at an angle. This arrangement of multiple light-absorbing units 20 further enhances the absorption and reflection of light, further reduces noise generation, and thus further improves the tire's visibility, aesthetics, and comfort. Simultaneously, this arrangement of multiple light-absorbing units 20 can also change the boundary layer structure of airflow, reduce turbulence formation, thereby lowering the air resistance coefficient. This reduces energy loss under high-speed driving conditions, improves tire fuel efficiency, and ultimately enhances the overall performance of the tire.

[0050] Specifically, when the light-absorbing unit 20 is disposed on the sidewall of the tread groove, the first preset direction is perpendicular to the tread, and the second preset direction is the width direction of the tread; or, the first preset direction is the width direction of the tread, and the second preset direction is perpendicular to the tread.

[0051] Specifically, when the light-absorbing unit 20 is disposed on the bottom of the tread groove, the first preset direction is the circumferential direction of the tread and the second preset direction is the width direction of the tread; or, the first preset direction is the width direction of the tread and the second preset direction is the circumferential direction of the tread.

[0052] Specifically, when the light-absorbing unit 20 is disposed on the tire sidewall, the first preset direction is the width direction of the tire sidewall and the second preset direction is the circumferential direction of the tire sidewall; or, the first preset direction is the circumferential direction of the tire sidewall and the second preset direction is the width direction of the tire sidewall, so that multiple light-absorbing units 20 are connected sequentially along the circumferential direction of the tire sidewall to form a ring of light-absorbing units 20 on the tire sidewall, thereby increasing the recognizability and aesthetics of the tire sidewall.

[0053] In this embodiment, the first preset direction and the second preset direction are located in the same plane, and the included angle between the first preset direction and the second preset direction is set at 90°. The included angle between the first preset direction and the second preset direction is between 0° and 180°, excluding 0° and 180°.

[0054] It should be noted that the angle between the first preset direction and the second preset direction is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, the angle between the first preset direction and the second preset direction is 45°, 60°, 110°, or 135°, etc.

[0055] like Figures 5 to 7As shown, the enclosure component 40 includes a plurality of enclosure structures 41 connected in sequence. Each enclosure structure 41 includes a first support portion 411 and a first connecting portion 412. The first support portion 411 is disposed on the marking area 11, and the first connecting portion 412 is disposed on the first support portion 411. Along the direction from the first support portion 411 to the first connecting portion 412, the cross-sectional area of ​​the first connecting portion 412 gradually decreases, so that the first connecting portion 412 has a first inclined surface and a second inclined surface. Wherein, the height H1 of the first connecting part 412 satisfies: 0.2mm≤H1≤0.5mm; the maximum distance L1 between the first inclined surface and the second inclined surface satisfies: 0.15mm≤L1≤0.35mm; and / or, the first inclined surface and the extension direction of the first supporting part 411 are set at a first included angle A1, the first included angle A1 satisfying: 60°≤A1≤80°; and / or, the second inclined surface and the extension direction of the first supporting part 411 are set at a second included angle A2, the second included angle A2 satisfying: 60°≤A2≤80°. In this way, the enclosure component 40 is connected to the main structure 10 through the first supporting part 411, ensuring the structural stability of the enclosure component 40. At the same time, the arrangement of the first connecting part 412 makes the enclosure structure 41 form a prism-like shape, which can be reflected by the first and second inclined surfaces when light shines on the tire, weakening part of the brightness of the light and ensuring the light absorption effect of the second light-absorbing recess 60. Meanwhile, the above-mentioned size settings can ensure that the enclosure structure 41 has good connection stability, ensure that the second light-absorbing recess 60 has good light absorption effect, and also facilitate the accuracy and flexibility of laser engraving.

[0056] In this embodiment, both the first inclined surface and the second inclined surface are inclined relative to the first supporting portion 411. The end of the first inclined surface away from the first supporting portion 411 is connected to the end of the second inclined surface away from the first supporting portion 411, so that the first connecting portion 412 is arranged in a triangular prism shape.

[0057] In this embodiment, the height H1 satisfies: H1=0.35mm, to ensure that the height H1 is more suitable.

[0058] In this embodiment, the maximum distance L1 satisfies: L1=0.25mm, to ensure that the maximum distance L1 is more appropriate.

[0059] In this embodiment, the first included angle A1 satisfies: A1=73°, to ensure that the first included angle A1 is more appropriate.

[0060] In this embodiment, the second included angle A2 satisfies: A2=73°, to ensure that the second included angle A2 is more suitable.

[0061] like Figure 2 and Figure 9As shown, the central component 30 includes a central structure 31 and multiple branch structures 32. The multiple branch structures 32 are spaced apart circumferentially along the central structure 31. The central structure 31 includes multiple central portions 311 connected in sequence. The multiple central portions 311 surround to form a first light-absorbing recess 50. A second light-absorbing recess 60 is formed between the outer wall surfaces of the surrounding component 40, two adjacent branch structures 32, and the central portions 311. In this way, the central component 30 is connected to the surrounding component 40 through the central structure 31 and the branch structures 32, and the multiple branch structures 32 divide the space into multiple second light-absorbing recesses 60, ensuring the light absorption reliability of the light-absorbing unit 20. At the same time, the central structure 31 forms the first light-absorbing recess 50 through the multiple central portions 311, giving the first light-absorbing recess 50 an irregular shape, thereby ensuring multi-directional scattering of light, achieving soft light reflection, reducing visual differences in brightness, and improving the recognizability and aesthetics of the marking area 11.

[0062] like Figure 7 As shown, the central portion 311 includes a second supporting portion 3111 and a second connecting portion 3112. The second supporting portion 3111 is disposed on the marking area 11, and the second connecting portion 3112 is disposed on the second supporting portion 3111. Along the direction from the second supporting portion 3111 to the second connecting portion 3112, the cross-sectional area of ​​the second connecting portion 3112 gradually decreases, so that the second connecting portion 3112 has a third inclined surface and a fourth inclined surface. Wherein, the height H2 of the second connecting part 3112 satisfies: 0.2mm≤H2≤0.5mm; the maximum distance L2 between the third and fourth inclined surfaces satisfies: 0.15mm≤L2≤0.35mm; and / or, the third inclined surface is set at a third angle A3 with the extension direction of the second bearing part 3111, and the third angle A3 satisfies: 60°≤A3≤80°; and / or, the fourth inclined surface is set at a fourth angle A4 with the extension direction of the second bearing part 3111, and the fourth angle A4 satisfies: 60°≤A4≤80°. In this way, the central part 311 is connected to the main structure 10 through the second bearing part 3111, ensuring the structural stability of the central part 311. At the same time, the arrangement of the second connecting part 3112 makes the central part 311 form a prism-like shape, which can be reflected by the third and fourth inclined surfaces when light shines on the tire, weakening part of the brightness of the light and ensuring the light absorption effect of the first light-absorbing recess 50. Meanwhile, the above-mentioned size settings can ensure that the central part 311 has good connection stability, ensure that the first light-absorbing recess 50 has good light absorption effect, and also facilitate the accuracy and flexibility of laser engraving.

[0063] In this embodiment, both the third and fourth inclined surfaces are inclined relative to the second support portion 3111. The end of the third inclined surface away from the second support portion 3111 is connected to the end of the fourth inclined surface away from the second support portion 3111, so that the second connecting portion 3112 is arranged in a triangular prism shape.

[0064] In this embodiment, the height H2 satisfies: H2=0.35mm, to ensure that the height H2 is more suitable.

[0065] In this embodiment, the maximum distance L2 satisfies: L2=0.25mm, to ensure that the maximum distance L2 is more appropriate.

[0066] In this embodiment, the third included angle A3 satisfies: A3=73°, to ensure that the third included angle A3 is more suitable.

[0067] In this embodiment, the fourth included angle A4 satisfies: A4=73°, to ensure that the fourth included angle A4 is more suitable.

[0068] like Figure 7 As shown, the branch structure 32 includes a third supporting part 321 and a third connecting part 322. The third supporting part 321 is disposed on the marking area 11, and the third connecting part 322 is disposed on the third supporting part 321. Along the direction from the third supporting part 321 to the third connecting part 322, the cross-sectional area of ​​the third connecting part 322 gradually decreases, so that the third connecting part 322 has a fifth inclined surface and a sixth inclined surface. The height H3 of the third connecting part 322 satisfies: 0.2mm ≤ H3 ≤ 0.5mm; the maximum distance L3 between the fifth and sixth inclined surfaces satisfies: 0.15mm ≤ L3 ≤ 0.35mm; and / or, the fifth inclined surface is set at a fifth angle A5 with the extension direction of the third supporting part 321, and the fifth angle A5 satisfies: 60° ≤ A5 ≤ 80°; and / or, the sixth inclined surface is set at a sixth angle A6 with the extension direction of the third supporting part 321, and the sixth angle A6 satisfies: 60° ≤ A6 ≤ 80°. In this way, the branch structure 32 is connected to the main structure 10 through the third supporting part 321, ensuring the structural stability of the branch structure 32. Simultaneously, the arrangement of the second connecting part 3112 causes the branch structure 32 to form a prism-like shape, allowing light to be reflected by the fifth and sixth inclined surfaces when it shines on the tire, reducing some of the light's brightness and ensuring the light absorption effect of the second light-absorbing recess 60. Furthermore, the aforementioned dimensional settings ensure good connection stability of the branch structure 32, guarantee good light absorption of the second light-absorbing recess 60, and also benefit the accuracy and flexibility of laser engraving.

[0069] In this embodiment, both the fifth and sixth inclined surfaces are inclined relative to the third support portion 321. The end of the fifth inclined surface away from the third support portion 321 is connected to the end of the sixth inclined surface away from the third support portion 321, so that the third connecting portion 322 is arranged in a triangular prism shape.

[0070] In this embodiment, the height H3 satisfies: H3=0.35mm, to ensure that the height H3 is more suitable.

[0071] In this embodiment, the maximum distance L3 satisfies: L3=0.25mm, to ensure that the maximum distance L3 is more suitable.

[0072] In this embodiment, the fifth included angle A5 satisfies: A5=70°, to ensure that the fifth included angle A5 is more suitable.

[0073] In this embodiment, the sixth included angle A6 satisfies: A6=70°, to ensure that the sixth included angle A6 is more suitable.

[0074] like Figure 3 and Figure 4 As shown, the first light-absorbing recess 50 has a first opening 51 at the end away from the main structure 10, and the maximum area S1 of the first opening 51 satisfies: 0.03 mm. 2 ≤S1≤0.13mm 2 ; and / or, the first light-absorbing recess 50 has a second opening 52 at one end near the main structure 10, and the maximum area S2 of the second opening 52 satisfies: 0.00071 mm 2 ≤S2≤0.0177mm 2 In this way, the above arrangement makes the range of the first opening 51 and the second opening 52 of the first light-absorbing recess 50 more appropriate, so as to ensure that the first light-absorbing recess 50 and the second light-absorbing recess 60 cooperate to absorb light and reflect light in a disordered manner, thus ensuring a soft reflection effect of the marking area 11 and avoiding the appearance of mottled "scalp" on the marking area 11, further ensuring the tire's recognizability and aesthetics.

[0075] Specifically, the first opening 51 is located within a circle with a diameter ranging from 0.3 mm to 0.4 mm.

[0076] Specifically, the second opening 52 is located within a circle with a diameter ranging from 0.03 mm to 0.15 mm.

[0077] like Figure 3 and Figure 4 As shown, the end of the second light-absorbing recess 60 away from the main structure 10 has a third opening 61, and the maximum area S3 of the third opening 61 satisfies: 0.03 mm. 2 ≤S3≤0.13mm 2; and / or, the second light-absorbing recess 60 has a fourth opening 62 at one end near the main structure 10, and the maximum area S4 of the fourth opening 62 satisfies: 0.00071 mm 2 ≤S4≤0.0177mm 2 In this way, the above arrangement makes the range of the third opening 61 and the fourth opening 62 of the second light-absorbing recess 60 more appropriate, so as to ensure that the second light-absorbing recess 60 and the first light-absorbing recess 50 absorb light in combination and reflect light in a disordered manner, thus ensuring a soft reflection effect of the marking area 11 and avoiding the appearance of mottled "scalp" on the marking area 11, further ensuring the tire's recognizability and aesthetics.

[0078] Specifically, the third opening 61 is located within a circle with a diameter ranging from 0.3 mm to 0.4 mm.

[0079] Specifically, the fourth opening 62 is located within a circle with a diameter ranging from 0.03 mm to 0.15 mm.

[0080] like Figure 8 As shown, the projection of the enclosure component 40 onto the marking area 11 is polygonal, and the maximum area S5 of the polygon satisfies: 0.25 mm. 2 ≤S5≤9mm 2 In this way, the above-mentioned arrangement makes the range of the enclosure component 40 more suitable and the range setting of the enclosure component 40 more flexible, improves the disorder of the arrangement of the second light-absorbing recess 60, further efficiently absorbs and converts incident light, further ensures the multi-directional scattering of light by the second light-absorbing recess 60, realizes soft reflection of light, reduces visual differences in brightness and darkness, and improves the recognizability and aesthetics of the marking area 11.

[0081] Specifically, the polygonal projection of the enclosure component 40 onto the marking area 11 lies within a square with a side length ranging from 0.5 mm to 3 mm.

[0082] Specifically, the irregular first light-absorbing recess 50 and second light-absorbing recess 60, compared with light-absorbing recesses formed by simple curves, arcs, and broken lines, can better absorb and reflect light, reduce the brightness of the marking area 11, and improve the tire's recognizability and aesthetics.

[0083] like Figure 2 and Figure 4As shown, the enclosure structure 41 is arranged in a zigzag shape, and the branch structure 32 includes a first branch 33 and a second branch 34. The first branch 33 is arranged in a straight line or a zigzag shape, with one end connected to the central structure 31 and the other end connected to the enclosure structure 41. The second branch 34 includes a main branch 341 and at least two secondary branches 342. One end of the main branch 341 is connected to the central structure 31, and the other end of the main branch 341 is connected to at least two secondary branches 342. The end of the secondary branch 342 away from the main branch 341 is connected to the enclosure structure 41. In this way, the branch structure 32 is connected to the central structure 31 and the surrounding structure 41 through the first branch member 33 and the second branch member 34. The second branch member 34 is connected to the two secondary branches 342 through the main branch 341, and is connected to the central structure 31 through the main branch 341 and to the surrounding structure 41 through the secondary branches 342, ensuring the reliability of the formation of the second light-absorbing recess 60. At the same time, the surrounding structure 41 is arranged in a zigzag shape, and the branch structure 32, through the zigzag shape of the first branch member 33 and the multi-structure arrangement of the second branch member 34, makes the inner wall projection of the second light-absorbing recess 60 on the light-absorbing area have an irregular shape, ensuring that the second light-absorbing recess 60 scatters light in multiple directions, achieving soft light reflection, reducing visual differences in brightness and darkness, and improving the recognizability and aesthetics of the marking area 11.

[0084] Example 2

[0085] The tire in Embodiment 2 differs from that in Embodiment 1 in that the shape of the first branch 33 is different, and the connection positions of the first branch 33 and the second branch 34 with the central structure 31 and the surrounding structure 41 are different.

[0086] like Figure 11As shown, the enclosure structure 41 is arranged in a zigzag shape, and the branch structure 32 includes a first branch 33 and a second branch 34. One end of the first branch 33 is connected to the connection point of two adjacent central portions 311, and the other end of the first branch 33 is connected to the bend of the enclosure structure 41. The second branch 34 includes a main branch 341 and at least two secondary branches 342. One end of the main branch 341 is connected to the connection point of two adjacent central portions 311, and the other end of the main branch 341 is connected to at least two secondary branches 342. The end of the secondary branch 342 away from the main branch 341 is connected to the bend of the enclosure structure 41. The first branch 33, the main branch 341, and the secondary branches 342 are all arranged in a straight line. Thus, the first branch 33 and the main branch 341 are both connected to the connection point of two adjacent central portions 311 of the central structure 31, that is, the first branch 33 and the main branch 341 are both connected to the bend of the central structure 31. Meanwhile, the first branch 33 and the secondary branch 342 are both connected to the bends of the enclosure structure 41, and the first branch, the main branch 341 and the secondary branch 342 are all arranged in a straight line, so that the bends of the enclosure component 40 and the central component 30 are connected by a straight line. This makes it easier for the staff to adjust the area of ​​the second light-absorbing recess 60 by adjusting the bends, thus making the area adjustment of the second light-absorbing recess 60 convenient and improving the processing flexibility of the staff. It also allows the second light-absorbing recess 60 to be adjusted to different shapes and areas to improve the reflective writing effect of the second light-absorbing recess 60, and further improve the recognizability and aesthetics of the indicated area.

[0087] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0088] The surface of the tire's main structure has a marking area; a light-absorbing unit is disposed on the marking area, the light-absorbing unit includes a central component and a surrounding component, the central component has a first light-absorbing recess, the surrounding component is sleeved on the central component, and a plurality of second light-absorbing recesses are formed around the surrounding component and the central component, the plurality of second light-absorbing recesses are arranged sequentially along the circumference of the surrounding component, the first light-absorbing recess and the second light-absorbing recess are both used to absorb external light; wherein, along the direction from the central component to the main structure, the cross-sectional area of ​​the first light-absorbing recess gradually decreases; and / or, the cross-sectional area of ​​the second light-absorbing recess gradually decreases. In this way, when external light shines on the tire, the inner walls of both the first and second light-absorbing recesses can reflect the light multiple times, causing light attenuation and reducing its brightness. This achieves the effect of absorbing and converting incident light, reducing the tire's specular reflection intensity, increasing its diffuse reflectivity, reducing visual differences in brightness, increasing the reflective area of ​​light, and weakening the intensity of light reflection. This results in a larger grayscale value in the marking area, making it appear darker and blacker under light, which is beneficial for consumer recognition. This improves the tire's recognizability and aesthetics, thus solving the problem of poor tire recognizability and aesthetics in existing technologies. Simultaneously, the arrangement of the first and second light-absorbing recesses also increases the roughness of the main structure, disrupting the stability of airflow during tire operation, disturbing the sound wave propagation path in the airflow, preventing the formation of regular sound wave superposition, suppressing the periodic compression and release of air in the tire grooves, reducing high-frequency noise generated by air column resonance, and dispersing the noise frequency to a frequency band insensitive to the human ear, thereby reducing the peak sound pressure level and lowering tire noise. At the same time, the above settings can also increase the contact area between the tire rubber and the mold during the vulcanization process, avoiding the situation where the tire cannot be degummed after vulcanization and the rubber sticks to the mold, thus reducing the cost of mold maintenance and cleaning.
