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 structure having a marking area on its surface; and a marking unit including a supporting structure and multiple marking structures, wherein the supporting structure is disposed on the marking area, and the multiple marking structures are spaced apart on the supporting structure along a first preset direction. Each marking structure has multiple sets of light-absorbing recesses, each set of light-absorbing recesses including multiple light-absorbing recesses, and each of two adjacent sides of the marking structure has at least one set of light-absorbing recesses. The multiple light-absorbing recesses in each set of light-absorbing recesses are spaced apart along a second preset direction to absorb external light. The second preset direction is parallel to the extension direction of the marking structure, and the first preset direction is at an angle to the second preset direction.

[0007] Furthermore, along the direction from the supporting structure to the sign structure, the cross-sectional area of ​​the sign structure gradually decreases, so that the sign structure has a first inclined surface and a second inclined surface, and multiple sets of light-absorbing recesses are respectively arranged on the first inclined surface and the second inclined surface; wherein, along the second preset direction, the multiple light-absorbing recesses on the first inclined surface and the multiple light-absorbing recesses on the second inclined surface are staggered.

[0008] Furthermore, the end of the first inclined plane away from the load-bearing structure is connected to the end of the second inclined plane away from the load-bearing structure, so that the sign structure has an edge; wherein, the height H1 of the sign structure satisfies: 0.2mm≤H1≤0.5mm; and / or, there is a distance S1 between the edges of two adjacent sign structures, the distance S1 satisfies: 0.15mm≤S1≤0.8mm; there is a minimum distance S2 between two adjacent sign structures, the minimum distance S2 satisfies: 0.01mm≤S2≤0.1mm.

[0009] Furthermore, the first inclined surface is set at a first angle A1 with the extension direction of the load-bearing structure, 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 load-bearing structure, and the second angle A2 satisfies: 60°≤A2≤80°.

[0010] Furthermore, the light-absorbing recess includes a first recess and a second recess that are interconnected. The first recess has a first sidewall, and the second recess has a second sidewall. At least a portion of the first sidewall is provided as an arcuate surface, and the arcuate surface has an arcuate projection on the supporting structure. The diameter D1 of the arcuate projection satisfies: 0.03mm≤D1≤0.1mm. At least a portion of the second sidewall is provided as a plane, and the plane has a straight projection on the supporting structure. The length L1 of the straight projection satisfies: 0mm≤L1≤0.1mm.

[0011] Furthermore, the arc projection has a center, and on the first inclined plane, there is a distance S3 between two adjacent centers, where distance S3 satisfies: 0.03mm≤S3≤0.1mm; and / or, on the second inclined plane, there is a distance S4 between two adjacent centers, where distance S4 satisfies: 0.03mm≤S4≤0.1mm; and / or, along the second preset direction, there is a staggered distance S5 between the centers on the first inclined plane and the centers on the second inclined plane, where distance S5 satisfies: 0.03mm≤S5≤0.1mm.

[0012] Furthermore, the tangent direction of the arc-shaped surface is set at a third included angle A3 with the extension direction of the load-bearing structure, and the third included angle A3 satisfies: 20°≤A3≤90°; and / or, the extension direction of the second sidewall is set at a fourth included angle A4 with the extension direction of the load-bearing structure, and the fourth included angle A4 satisfies: 20°≤A4≤90°.

[0013] Furthermore, the first sidewall has a height H2 between its end near the edge and the edge, where the height H2 satisfies: 0.08mm≤H2≤0.12mm; and / or, the second sidewall has a height H3 between its end near the load-bearing structure and the load-bearing structure, where the height H3 satisfies: 0.08mm≤H3≤0.12mm.

[0014] Furthermore, the opening of the light-absorbing recess has a width W1 and a length L2, wherein the width W1 satisfies: 0.03mm≤W1≤0.1mm; and the length L2 satisfies: 0.1mm≤L1≤0.35mm.

[0015] Furthermore, the light-absorbing recess has an inner wall, which includes a plurality of sequentially connected sub-sidewalls. The projection of the inner wall onto the supporting structure is polygonal, and the polygon has a geometric center. Specifically, on the first inclined surface, there is a distance S6 between two adjacent geometric centers, and the distance S6 satisfies: 0.04mm≤S6≤0.08mm; and / or, on the second inclined surface, there is a distance S7 between two adjacent geometric centers, and the distance S7 satisfies: 0.04mm≤S4≤0.08mm; and / or, along the second preset direction, there is a staggered distance S8 between the center on the first inclined surface and the geometric center on the second inclined surface, and the distance S8 satisfies: 0.04mm≤S8≤0.08mm.

[0016] Applying the technical solution of this invention, the surface of the tire's main structure has a marking area. The marking unit includes a supporting structure and multiple marking structures. The supporting structure is disposed on the marking area, and the multiple marking structures are spaced apart on the supporting structure along a first preset direction. Each marking structure has multiple sets of light-absorbing recesses, and each set of light-absorbing recesses includes multiple light-absorbing recesses. At least one set of light-absorbing recesses is present on each of two adjacent sides of the marking structure. The multiple light-absorbing recesses in each set are spaced apart along a second preset direction to absorb external light. The second preset direction is parallel to the extending direction of the marking structure, and the first preset direction forms an angle with the second preset direction. In this way, when external light shines on the tire, the inner walls of the multiple light-absorbing recesses on both sides of the marking structure can reflect the light multiple times, causing the light to attenuate and weakening its brightness. This achieves the effect of absorbing and converting the incident light, reducing the specular reflection intensity of the tire, increasing the tire's diffuse reflectivity, reducing visual differences in brightness, increasing the reflective area of ​​the light, and weakening the intensity of light reflection. This results in a larger gray 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, thereby solving the problem of poor tire recognizability and aesthetics in existing technologies. Meanwhile, the arrangement of multiple marking structures not only enhances the light-absorbing capacity of the light-absorbing recesses, thus improving tire visibility, but also increases the roughness of the main structure. This disrupts the stability of airflow during tire operation, disturbs the sound wave propagation path, prevents the formation of regular sound wave superposition, suppresses the periodic compression and release of air within the tire grooves, reduces high-frequency noise caused by air column resonance, and disperses noise frequencies to a range insensitive to the human ear, thereby lowering the peak sound pressure level and reducing tire noise. Furthermore, the multiple light-absorbing recesses increase the contact area between the tire rubber and the mold during vulcanization, preventing the tire from failing to debond after vulcanization and avoiding rubber sticking to the mold, thus reducing mold maintenance and cleaning costs.

[0036] To address the problem of poor recognizability and aesthetics of existing tires, this application provides a tire.

[0037] Example 1

[0038] like Figures 1 to 6 As shown, the tire includes a main structure 10 and a marking unit 20. The surface of the main structure 10 has a marking area 11. The marking unit 20 includes a supporting structure 30 and multiple marking structures 40. The supporting structure 30 is disposed on the marking area 11, and the multiple marking structures 40 are spaced apart on the supporting structure 30 along a first preset direction. Each marking structure 40 has multiple sets of light-absorbing recesses 50, and each set of light-absorbing recesses 50 includes multiple light-absorbing recesses 50. At least one set of light-absorbing recesses 50 is respectively provided on two adjacent sides of the marking structure 40. The multiple light-absorbing recesses 50 in each set of light-absorbing recesses 50 are spaced apart along a second preset direction to absorb external light. The second preset direction is parallel to the extension direction of the marking structure 40, and the first preset direction is at an angle to the second preset direction.

[0039] Applying the technical solution of this embodiment, the surface of the tire's main structure 10 has a marking area 11. The marking unit 20 includes a supporting structure 30 and multiple marking structures 40. The supporting structure 30 is disposed on the marking area 11, and the multiple marking structures 40 are spaced apart on the supporting structure 30 along a first preset direction. Each marking structure 40 has multiple sets of light-absorbing recesses 50, and each set of light-absorbing recesses 50 includes multiple light-absorbing recesses 50. At least one set of light-absorbing recesses 50 is provided on each of two adjacent sides of the marking structure 40. The multiple light-absorbing recesses 50 in each set of light-absorbing recesses 50 are spaced apart along a second preset direction to absorb external light. The second preset direction is parallel to the extending direction of the marking structure 40, and the first preset direction is at an angle to the second preset direction. In this way, when external light shines on the tire, the inner walls of the multiple light-absorbing recesses 50 on the two sides of the marking structure 40 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 reflective area of ​​the light, and weakening the reflection intensity of the light. This makes the gray value of the marking area 11 larger, presenting a darker and blacker effect under light, which is beneficial to consumers' recognition. This improves the tire's recognizability and aesthetics, thereby solving the problem of poor tire recognizability and aesthetics in the existing technology. Meanwhile, the arrangement of multiple marking structures 40 not only further enhances the light-absorbing capacity of the light-absorbing recesses 50, thus improving tire visibility, but also increases the roughness of the main structure 10. This disrupts the stability of airflow during tire operation, disturbs the sound wave propagation path, prevents the formation of regular sound wave superposition, suppresses the periodic compression and release of air within the tire grooves, reduces high-frequency noise caused by air column resonance, and disperses noise frequencies to a range insensitive to the human ear, thereby lowering the peak sound pressure level and reducing tire noise. Furthermore, the multiple light-absorbing recesses 50 increase the contact area between the tire rubber and the mold during vulcanization, preventing the tire from failing to debond after vulcanization and avoiding rubber adhesion to the mold, thus reducing mold maintenance and cleaning costs.

[0040] like Figure 1 As shown, the main structure 10 includes a tread and a sidewall, and the tread is provided with tread grooves.

[0041] In this embodiment, multiple marking units 20 are arranged sequentially on the marking area 11. This arrangement of multiple marking units 20 further enhances light absorption and reflection, reduces noise generation, and thus improves tire visibility, aesthetics, and comfort. Simultaneously, the arrangement of multiple marking units 20 also alters the boundary layer structure of airflow, reducing turbulence and lowering the drag coefficient. This reduces energy loss under high-speed driving conditions, improves fuel efficiency, and ultimately enhances the overall performance of the tire.

[0042] Optionally, the marking unit 20 is disposed on the side wall of the patterned groove; and / or, the marking unit 20 is disposed on the bottom of the patterned groove.

[0043] Optionally, the marking unit 20 is disposed on the tire sidewall.

[0044] Specifically, when the marking unit 20 is disposed on the side wall of the tread groove, the first preset direction is the direction perpendicular to the tread, and the second preset direction is the width direction of the tread.

[0045] Specifically, when the marking 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.

[0046] Specifically, when the marking unit 20 is set on the tire sidewall, the first preset direction is the width direction of the tire sidewall, the second preset direction is the circumferential direction of the tire sidewall, and multiple marking units 20 are connected sequentially along the circumferential direction of the tire sidewall to form a ring of marking units 20 on the tire sidewall, so as to increase the recognizability and aesthetics of the tire sidewall.

[0047] 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°.

[0048] 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.

[0049] In this embodiment, the marking unit 20 is processed using laser engraving technology, ensuring the reliability of the marking unit 20 processing. Simultaneously, laser engraving, through high-precision control, can form 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 outside world, 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 the fatigue resistance of the marking area 11, and ultimately extending the tire's service life.

[0050] like Figure 2 , Figure 4 and Figure 5 As shown, along the direction from the supporting structure 30 to the marking structure 40, the cross-sectional area of ​​the marking structure 40 gradually decreases, so that the marking structure 40 has a first inclined surface 41 and a second inclined surface 42, and multiple sets of light-absorbing recesses 50 are respectively disposed on the first inclined surface 41 and the second inclined surface 42. Specifically, along the second preset direction, the multiple light-absorbing recesses 50 on the first inclined surface 41 and the multiple light-absorbing recesses 50 on the second inclined surface 42 are staggered. Thus, when light shines on the tire, it is first reflected by the first inclined surface 41 and the second inclined surface 42, weakening part of the light's brightness, and then further reflected by the multiple light-absorbing recesses 50 on the first inclined surface 41 and the second inclined surface 42, further weakening the light's brightness. This improves the light absorption effect of the marking structure 40, further enhancing the recognizability and aesthetics of the marking area 11. Meanwhile, the staggered arrangement of multiple light-absorbing recesses 50 on the first inclined surface 41 and multiple light-absorbing recesses 50 on the second inclined surface 42 can, on the one hand, prevent the marking structure 40 from breaking compared to the corresponding arrangement of light-absorbing recesses 50 on the two inclined surfaces, thus ensuring the rigidity and wear resistance of the marking structure 40; on the other hand, it reduces the orderly arrangement of multiple light-absorbing recesses 50, enriches the light absorption and reflection path of the marking structure 40, and further improves the tire's recognizability.

[0051] In this embodiment, both the first inclined surface 41 and the second inclined surface 42 are inclined relative to the load-bearing structure.

[0052] like Figure 2 , Figure 4 and Figure 5As shown, the end of the first inclined surface 41 away from the supporting structure 30 is connected to the end of the second inclined surface 42 away from the supporting structure 30, so that the sign structure 40 has an edge 43. The height H1 of the sign structure 40 satisfies: 0.2mm ≤ H1 ≤ 0.5mm; and / or, there is a distance S1 between the edges 43 of two adjacent sign structures 40, where the distance S1 satisfies: 0.15mm ≤ S1 ≤ 0.8mm; and there is a minimum distance S2 between two adjacent sign structures 40, where the minimum distance S2 satisfies: 0.01mm ≤ S2 ≤ 0.1mm. Thus, the above configuration limits the sign structure 40 to a triangular prism structure, allowing the sign structure 40 to reflect light while maintaining a simple and stable structure, and also facilitating processing and molding. Meanwhile, the aforementioned dimensional settings ensure that the height of the marking structure 40 and the spacing between multiple marking structures 40 are appropriate. On the one hand, this facilitates demolding from the mold, avoiding difficulties in delamination and rubber adhesion to the mold due to unsuitable dimensions, thus ensuring the ease of processing the marking unit 20 and reducing mold maintenance and cleaning costs. On the other hand, it also sets a reasonable processing range, ensuring both processing accuracy and flexibility. Furthermore, these settings protect the marking area 11 from direct impacts from hard objects such as stones, reducing surface wear and extending tire lifespan.

[0053] Specifically, the height H1 of the marking structure 40 was kept constant at 0.35mm. Experiments were conducted with the spacing S1 set to 0.2mm, 0.25mm, 0.3mm, 0.4mm, 0.6mm, and 0.8mm. The experimental results are shown in Table 1. A smaller brightness L value indicates better light absorption. A change in molding feasibility from B to A indicates better vulcanization processing, and a change in appearance aesthetics from C to A indicates better aesthetics. As the spacing S1 decreases, the light absorption effect of the marking structure 40 improves. When the spacing S1 decreases from 0.6mm to 0.2mm, the brightness difference in the marking area 11 becomes smaller. When the spacing S1 decreases from 0.3mm to 0.2mm, the light absorption effect of the marking structure 40 remains basically consistent. Considering the feasibility of tire vulcanization processing, the optimal light absorption effect is achieved when the spacing S1 = 0.25mm.

[0054] Table 1

[0055]

[0056] Specifically, with the spacing S1 set to remain constant at 0.25mm, experiments were conducted with height H1 set to 0.2mm, 0.3mm, 0.35mm, 0.4mm, and 0.5mm. The experimental structure is shown in Table 2. A smaller brightness L value indicates better light absorption. The molding feasibility ranges from B to A, indicating greater advantages for vulcanization. The aesthetic appeal ranges from C to A, indicating better appearance. When height H1 is between 0.3mm and 0.4mm, the light absorption effect of the marking structure 40 is basically the same. As height H1 increases from 0.4mm to 0.5mm, the change in light absorption effect of the marking structure 40 is relatively small. Considering the feasibility of tire vulcanization, the optimal light absorption effect is achieved when height H1 = 0.35mm.

[0057] Table 2

[0058]

[0059] In this embodiment, the minimum spacing S2 satisfies: S2=0.03mm, to ensure that the minimum spacing S2 is more suitable.

[0060] like Figure 4 As shown, the first inclined surface 41 and the extending direction of the supporting structure 30 are set at a first angle A1, where the first angle A1 satisfies: 60°≤A1≤80°; and / or, the second inclined surface 42 and the extending direction of the supporting structure 30 are set at a second angle A2, where the second angle A2 satisfies: 60°≤A2≤80°. This arrangement ensures that the tilt angles of the first inclined surface 41 and the second inclined surface 42 are more suitable, resulting in more uniform light reflection on the inclined surfaces, effectively reducing specular reflection intensity and improving tire visibility. Simultaneously, this arrangement facilitates manufacturing and makes the connection between the marking structure 40 and the supporting structure 30 more stable, ensuring the structural stability of the marking structure 40.

[0061] In this embodiment, the first included angle A1 satisfies: A1=70°, to ensure that the first included angle A1 is more appropriate.

[0062] In this embodiment, the second included angle A2 satisfies: A2=70°, to ensure that the second included angle A2 is more suitable.

[0063] like Figure 2 and Figure 6As shown, the light-absorbing recess 50 includes a first recess 51 and a second recess 52 that are interconnected. The first recess 51 has a first sidewall 511, and the second recess 52 has a second sidewall 521. At least a portion of the first sidewall 511 is arc-shaped, and the arc-shaped surface has an arc-shaped projection on the supporting structure 30. The diameter D1 of the arc-shaped projection satisfies: 0.03mm ≤ D1 ≤ 0.1mm. At least a portion of the second sidewall 521 is planar, and the planar surface has a straight-line projection on the supporting structure 30. The length L1 of the straight-line projection satisfies: 0mm ≤ L1 ≤ 0.1mm. Thus, the light-absorbing recess 50 formed by the first recess 51 and the second recess 52 has richer structural features. The arc-shaped sidewall of the first recess 51 and the planar sidewall of the second recess 52 can absorb and scatter incident light from multiple directions, increasing the contrast and clarity of the marking area 11. Meanwhile, the above-mentioned design also facilitates mold demolding, avoids difficulties in degumming and rubber sticking to the mold, ensures the processing convenience of the light-absorbing recess 50, and reduces the maintenance and cleaning costs of the mold.

[0064] In this embodiment, the diameter D1 satisfies: D1=0.06mm, to ensure that the diameter D1 is more suitable.

[0065] In this embodiment, the effect is better when the length L1 satisfies 0.02mm≤L1≤0.03mm.

[0066] like Figure 6 As shown, the arc projection has a center. On the first inclined surface 41, there is a distance S3 between two adjacent centers, where the distance S3 satisfies: 0.03mm ≤ S3 ≤ 0.1mm; and / or, on the second inclined surface 42, there is a distance S4 between two adjacent centers, where the distance S4 satisfies: 0.03mm ≤ S4 ≤ 0.1mm; and / or, along the second preset direction, there is a staggered distance S5 between the centers on the first inclined surface 41 and the centers on the second inclined surface 42, where the distance S5 satisfies: 0.03mm ≤ S5 ≤ 0.1mm. This arrangement allows the multiple light-absorbing recesses 50 on the first and second inclined surfaces 41 to be arranged more appropriately, avoiding the phenomenon of low light absorption due to unreasonable arrangement of the light-absorbing recesses 50. This improves the light absorption and reflection effect of the sign structure 40, further enhancing the recognizability and aesthetics of the sign area 11. Meanwhile, the rational arrangement of multiple light-absorbing recesses (50) further disrupts airflow, reducing tire noise and improving driving comfort. Furthermore, the aforementioned dimensional settings facilitate laser engraving, enhancing its accuracy and flexibility, and ensuring processing efficiency.

[0067] In this embodiment, the spacing S3 satisfies: S3=0.06mm, to ensure that the spacing S3 is more appropriate.

[0068] In this embodiment, the spacing S4 satisfies: S4=0.06mm, to ensure that the spacing S4 is more appropriate.

[0069] In this embodiment, the spacing S5 satisfies: S5=0.06mm, to ensure that the spacing S5 is more appropriate.

[0070] like Figure 5 As shown, the tangent direction of the arc-shaped surface forms a third angle A3 with the extension direction of the supporting structure 30, where the third angle A3 satisfies: 20°≤A3≤90°; and / or, the extension direction of the second sidewall 521 forms a fourth angle A4 with the extension direction of the supporting structure 30, where the fourth angle A4 satisfies: 20°≤A4≤90°. This arrangement allows the light-absorbing recess 50 to have a larger opening, ensuring that light fully enters the light-absorbing recess 50 and is reflected by the first sidewall 511 and the second sidewall 521, thus improving the light absorption and reflection effect of the light-absorbing recess 50 and enhancing the recognizability and aesthetics of the marking area 11.

[0071] In this embodiment, the third included angle A3 satisfies: A3=90°, to ensure that the third included angle A3 is more suitable.

[0072] In this embodiment, the fourth included angle A4 satisfies: A4=45°, to ensure that the fourth included angle A4 is more suitable.

[0073] like Figure 5 As shown, the first sidewall 511 has a height H2 between its end near the edge 43 and the edge 43, where the height H2 satisfies: 0.08mm ≤ H2 ≤ 0.12mm; and / or, the second sidewall 521 has a height H3 between its end near the supporting structure 30 and the supporting structure 30, where the height H3 satisfies: 0.08mm ≤ H3 ≤ 0.12mm. This arrangement ensures that the light-absorbing recess 50 can fully absorb and reflect light while also maintaining a certain rigidity for the marking structure 40. This achieves reliable connection and support between the marking structure 40 and the supporting structure 30, thus guaranteeing the structural stability of the marking structure 40.

[0074] In this embodiment, the height H2 satisfies: H2=0.1mm, to ensure that the height H2 is more suitable.

[0075] In this embodiment, the height H3 satisfies: H3=0.1mm, to ensure that the height H3 is more suitable.

[0076] like Figure 3As shown, the opening of the light-absorbing recess 50 has a width W1 and a length L2. The width W1 satisfies: 0.03mm ≤ W1 ≤ 0.1mm; the length L2 satisfies: 0.1mm ≤ L1 ≤ 0.35mm. This arrangement further ensures that light can fully enter the light-absorbing recess 50, improving the light absorption and reflection effect of the light-absorbing recess 50, and also enhancing the recognizability and aesthetics of the marking area 11.

[0077] In this embodiment, the width W1 satisfies: W1=0.06mm, to ensure that the width W1 is more appropriate.

[0078] In this embodiment, the length L2 satisfies: L2=0.25mm, to ensure that the length L2 is more suitable.

[0079] Example 2

[0080] The difference between this embodiment and Embodiment 1 is that the projection shape of the inner wall of the light-absorbing recess 50 on the supporting structure 30 is different, that is, the inner wall of the light-absorbing recess 50 is arranged in multiple planes.

[0081] like Figure 7 As shown, the light-absorbing recess 50 has an inner wall, which includes multiple sequentially connected sub-sidewalls 60. The projection of the inner wall onto the supporting structure 30 is polygonal, with each polygon having a geometric center. Specifically, on the first inclined surface 41, there is a distance S6 between two adjacent geometric centers, satisfying: 0.04mm ≤ S6 ≤ 0.08mm; and / or, on the second inclined surface 42, there is a distance S7 between two adjacent geometric centers, satisfying: 0.04mm ≤ S4 ≤ 0.08mm; and / or, along a second preset direction, there is a staggered distance S8 between the centers on the first inclined surface 41 and the geometric centers on the second inclined surface 42, satisfying: 0.04mm ≤ S8 ≤ 0.08mm. This arrangement of the light-absorbing recess 50 provides greater flexibility for workers, and the multiple sub-sidewalls 60 can absorb and scatter incident light from multiple directions, increasing the contrast and clarity of the marking area 11.

[0082] In this embodiment, the spacing S6 satisfies: S6=0.06mm, to ensure that the spacing S6 is more appropriate.

[0083] In this embodiment, the spacing S7 satisfies: S7=0.06mm, to ensure that the spacing S7 is more appropriate.

[0084] In this embodiment, the spacing S8 satisfies: S8=0.06mm, to ensure that the spacing S8 is more appropriate.

[0085] In this embodiment, the projection of the inner wall of the light-absorbing recess 50 onto the supporting structure 30 is a regular hexagon.

[0086] Example 3

[0087] like Figure 8 As shown, the difference between this embodiment and embodiment two is that the projection of the inner wall of the light-absorbing recess 50 onto the supporting structure 30 is rectangular.

[0088] Based on experimental comparisons, as shown in Table 3, the light-absorbing recess 50 in Embodiment 1 has a better effect on light absorption and reflection than Embodiments 2 and 3, and is also more conducive to mold demolding.

[0091] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0092] The surface of the tire's main structure has a marking area. The marking unit includes a supporting structure and multiple marking structures. The supporting structure is disposed on the marking area, and the multiple marking structures are spaced apart on the supporting structure along a first preset direction. Each marking structure has multiple sets of light-absorbing recesses, and each set of light-absorbing recesses includes multiple light-absorbing recesses. At least one set of light-absorbing recesses is present on each of two adjacent sides of the marking structure. The multiple light-absorbing recesses in each set are spaced apart along a second preset direction to absorb external light. The second preset direction is parallel to the extending direction of the marking structure, and the first preset direction forms an angle with the second preset direction. In this way, when external light shines on the tire, the inner walls of the multiple light-absorbing recesses on both sides of the marking structure can reflect the light multiple times, causing the light to attenuate and weakening its brightness. This achieves the effect of absorbing and converting the incident light, reducing the specular reflection intensity of the tire, increasing the tire's diffuse reflectivity, reducing visual differences in brightness, increasing the reflective area of ​​the light, and weakening the intensity of light reflection. This results in a larger gray 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, thereby solving the problem of poor tire recognizability and aesthetics in existing technologies. Meanwhile, the arrangement of multiple marking structures not only enhances the light-absorbing capacity of the light-absorbing recesses, thus improving tire visibility, but also increases the roughness of the main structure. This disrupts the stability of airflow during tire operation, disturbs the sound wave propagation path, prevents the formation of regular sound wave superposition, suppresses the periodic compression and release of air within the tire grooves, reduces high-frequency noise caused by air column resonance, and disperses noise frequencies to a range insensitive to the human ear, thereby lowering the peak sound pressure level and reducing tire noise. Furthermore, the multiple light-absorbing recesses increase the contact area between the tire rubber and the mold during vulcanization, preventing the tire from failing to debond after vulcanization and avoiding rubber sticking to the mold, thus reducing mold maintenance and cleaning costs.
