Description

Technical Field

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

[0002] The design of the tire sidewall, tread grooves, and tread groove bottom directly affects the vehicle's aerodynamic performance, noise performance, and the tire's visual visibility.

[0003] In existing technologies, the outer surface of tires is generally made of vulcanized black rubber material, which has a smooth surface and mirror-like reflective properties. This design results in a uniform gray-scale reflection effect when the tire is illuminated, making it difficult to clearly identify the markings, markings, and trademarks, fonts, and patterns on the tread pattern, as well as the sidewall markings, fonts, and patterns. This leads to low visual contrast and limited aesthetic appeal. Furthermore, the smooth surface does not extend the light path, resulting in excessive brightness. This reduces the human eye's ability to discern surface details, significantly decreasing the readability of the markings and affecting their display effectiveness.

[0004] With the development of laser technology, laser engraving technology has been gradually applied in tire mold manufacturing. Compared with traditional processes, laser engraving can produce more refined patterns with dimensions down to the micrometer level, making it possible to vulcanize fine texture patterns on tires.

[0005] Although laser engraving technology has been applied to tire surface processing, traditional patterns are mostly periodic patterns. Such patterns are difficult to effectively change the optical properties of the tire surface, and the light absorption effect is not significantly improved, making it difficult to improve the aesthetics of the tire.

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0077] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0078] This utility model provides a tire with a tire tread pattern, which is used to set at predetermined locations on the tire. Please refer to... Figures 1 to 15 The tire tread pattern includes one or more tread units 1000; the tread unit 1000 includes two tread groups 100, which are arranged in a mirror symmetry with respect to the first symmetry line 110.

[0079] The tread pattern group 100 includes two preset patterns 10, which are mirror-symmetrically arranged with respect to the second symmetry line 120; the second symmetry line 120 is perpendicular to the first symmetry line 110; both the first symmetry line 110 and the second symmetry line 120 are parallel to the outer surface of the tire.

[0080] The preset pattern 10 includes multiple pattern segments 20.

[0081] The first configuration of the tread strip 20 is as follows: the tread strip 20 is a raised strip 21 protruding on the outer surface of the tire, and a groove 30 is formed between any two adjacent raised strips 21.

[0082] The second configuration of the tread pattern segment 20 is as follows: the tread pattern segment 20 is a recessed segment recessed on the outer surface of the tire, and a protrusion is formed between any two adjacent recessed segments.

[0083] It should be noted that neither the first symmetry line 110 nor the second symmetry line 120 are actual lines, but rather reference lines used to illustrate the hypothetical tire tread pattern.

[0084] It should be noted that, Figures 2 to 15 In the middle, lines are used to represent the pattern segments.

[0085] The tire texture, or texture pattern, of this application forms multiple grooves 30 or sets multiple recessed segments to cause multiple reflections of incident light, thereby extending the propagation path of incident light within the texture and enhancing light absorption efficiency, thus reducing local brightness. In this way, the texture pattern area can be divided into bright and dark areas of different brightness, so that the texture pattern area can form a brightness contrast, thereby improving the recognizability and aesthetics of the texture pattern area.

[0086] Optionally, texture patterns can be used to display preset text or preset patterns as identification information.

[0087] Optionally, the tire texture of this application is formed using laser engraving technology to achieve micron-level processing precision.

[0088] Optionally, when the tire tread pattern is set on the tire sidewall, the tread pattern can be continuously and clearly displayed during vehicle operation.

[0089] The tire tread pattern of this application can also effectively disperse the sound wave reflection path, reduce the concentrated propagation of noise, thereby reducing noise problems during tire use, improving driving comfort, and reducing noise pollution to the surrounding environment.

[0090] For example, tire textures created using nanoscale laser engraving technology can form a deep black texture on the tire similar to the reflection of light from moissanite, which is both aesthetically pleasing and noise-reducing.

[0091] This application achieves micron-level processing precision through laser engraving technology, ensuring the performance stability and durability of tires under various usage conditions. This high-precision processing not only improves the wear resistance and anti-aging performance of tires, but also extends their service life, reduces replacement frequency, and thus reduces maintenance costs and environmental burden.

[0092] Specifically, the multiple tread units 1000 of the tire tread are distributed in an array.

[0093] Optionally, all tread segments 20 of the tire tread are raised segments 21; or, all tread segments 20 of the tire tread are recessed segments.

[0094] In this application, the preset part is located on the tire tread or the tire sidewall. That is, the outer surface of the tire refers to the tire tread or the tire sidewall.

[0101] Optionally, the value of R is greater than or equal to 5 mm.

[0102] In this application, optionally, the length L of the pattern unit 1000 ranges from 3.4 mm to 4.25 mm.

[0103] In this application, optionally, the width W of the pattern unit 1000 is in the range of 3.12 mm to 5.12 mm; wherein the width direction of the pattern unit 1000 is perpendicular to its length direction.

[0104] In this application, the protrusion height H of the convex strip 21 ranges from 0.2 mm to 0.5 mm; for example, the protrusion height H of the convex strip 21 is 0.35 mm. The concave depth of the concave strip ranges from 0.2 mm to 0.5 mm, and the concave depth of the concave strip is 0.35 mm.

[0105] In this application, as Figure 16 As shown, the cross-section of the patterned stripe 20 perpendicular to its extension direction is trapezoidal or triangular. Preferably, the trapezoid is an isosceles trapezoid, and the triangle is an isosceles triangle.

[0106] Specifically, when the patterned strip 20 is a convex strip 21, the direction from the longer base to the shorter base of the trapezoid is the same as the convex direction of the convex strip 21, and the direction from the base to the vertex of the triangle is the same as the convex direction of the convex strip 21. When the patterned strip 20 is a concave strip, the direction from the longer base to the shorter base of the trapezoid is the same as the concave direction of the concave strip, and the direction from the base to the vertex of the triangle is the same as the concave direction of the concave strip.

[0107] Optionally, the length d1 of the shorter base of the trapezoid can range from 0.01 mm to 0.05 mm, for example, d1 is 0.03 mm.

[0108] Optionally, the angle α between the longer base and the side of the trapezoid is 70 degrees; the angle between the base and the side of the triangle is 70 degrees.

[0109] Optionally, such as Figure 16 As shown, when the patterned strip 20 is a raised strip 21, the cross-section of the groove 30 perpendicular to its extension direction is trapezoidal or triangular, preferably isosceles trapezoid or isosceles triangle. Optionally, the length d2 of the shorter base of this trapezoid ranges from 0.01mm to 0.05mm, for example, d2 is 0.03mm.

Optionally, the length d3 of the shorter base of this trapezoid ranges from 0.01 mm to 0.05 mm, for example, d3 is 0.03 mm.

[0112] Optionally, d3 equals d1.

The first center line 40 is perpendicular to the first symmetry line 110 and the second symmetry line 120. The multi-layer pattern strip structure 41 is arranged sequentially along a radial direction perpendicular to the first center line 40.

[0115] It should be noted that the first center line 40 is not an actual line, but a reference line used to illustrate the hypothetical tire tread pattern.

[0116] In this embodiment, the multi-layer pattern strip structure 41 of the preset pattern 10 includes a multi-layer first pattern strip structure 411. The first pattern strip structure 411 includes two first pattern strip segments 412 that are arranged opposite to each other and located on both sides of the first center line 40.

[0118] It should be noted that each first pattern segment 412 is a pattern segment 20.

[0119] Optionally, the two first patterned strip segments 412 of the first patterned strip structure 411 are arranged in a centrally symmetrical manner with respect to the first center line 40.

[0120] Specifically, when the extension trajectory of the first patterned stripe 412 is a broken line segment, the broken line segment includes a first straight line segment 4121 and a second straight line segment 4122. The first end of the first straight line segment 4121 and the first end of the second straight line segment 4122 are connected, and the first straight line segment 4121 and the second straight line segment 4122 are set at an included angle. Optionally, the first straight line segment 4121 and the second straight line segment 4122 are set at an obtuse angle. For example, the included angle θ between the first straight line segment 4121 and the second straight line segment 4122 is 106 degrees.

[0121] Optionally, when the extension trajectories of the two first patterned stripe segments 412 of the first patterned stripe structure 411 are both broken line segments, the first straight line segments 4121 of the two first patterned stripe segments 412 of the first patterned stripe structure 411 are parallel to each other; the second straight line segments 4122 of the two first patterned stripe segments 412 of the first patterned stripe structure 411 are parallel to each other.

[0165] Example 2

[0166] In this embodiment, as Figures 12 to 15 As shown, the preset pattern 10 includes two third patterns 50. The two third patterns 50 of the preset pattern 10 are mirror-symmetrically arranged with respect to the third symmetry line 51. The third symmetry line 51 is parallel to the outer surface of the tire. The third symmetry line 51 passes through the intersection of the first symmetry line 110 and the second symmetry line 120, and the angle between the third symmetry line 51 and the first symmetry line 110 is equal to the angle between the third symmetry line 51 and the second symmetry line 120.

[0167] It should be noted that the third symmetry line 51 is not an actual line, but a reference line used to illustrate the hypothetical tire tread pattern.

[0168] In this embodiment, the third tread pattern 50 includes multiple tread strip groups, and each tread strip group includes multiple tread strip segments 20; the extension trajectory of each tread strip segment 20 is an arc. In each tread strip group, the diameters of the multiple tread strip segments 20 are different, and the central axes of the multiple tread strip segments 20 coincide; wherein, the central axis refers to the axis passing through the center of the circle, and the central axis is perpendicular to the outer surface of the tire.

The pattern segment 20 of the fourth pattern group 64 is the fifteenth pattern segment 641, meaning the fourth pattern group 64 includes multiple fifteenth pattern segments 641. All of the multiple fifteenth pattern segments 641 protrude towards the direction close to the third symmetry line 51. The second ends of all of the multiple fifteenth pattern segments 641 extend to the outermost twelfth pattern segment 611 of the first pattern group 61.

The pattern segment 20 of the fifth pattern group 65 is the sixteenth pattern segment 651, meaning the fifth pattern group 65 includes multiple sixteenth pattern segments 651. All sixteenth pattern segments 651 protrude towards the direction near the third symmetry line 51.

[0183] In this embodiment, the third pattern 50 further includes a sixth pattern group 66, which is located on the side of the first pattern group 61 near the second center line 52. The pattern segment 20 of the sixth pattern group 66 is the seventeenth pattern segment 661, that is, the sixth pattern group 66 includes multiple seventeenth pattern segments 661. The second pattern group 62, the third pattern group 63 and the fifth pattern group 65 are all located on the side of the sixth pattern group 66 near the third symmetry line 51. The multiple seventeenth pattern segments 661 protrude in the direction of approaching the third symmetry line 51.

[0184] The first ends of multiple seventeenth pattern segments 661 extend to the innermost twelfth pattern segment 611 of the first pattern group 61, and the second ends of at least some seventeenth pattern segments 661 extend to the first symmetry line 110.

[0185] In the sixth pattern strip group 66, the seventeenth pattern strip 661 closest to the third symmetry line 51 is the outermost seventeenth pattern strip 661. The first ends of the multiple thirteenth pattern strips 621 all extend to the outermost seventeenth pattern strip 661 of the sixth pattern strip group 66.

[0187] In this embodiment, the third pattern 50 further includes a seventh pattern group 67, which is located on the side of the first pattern group 61 closer to the first line of symmetry 110, and on the side of the sixth pattern group 66 away from the third line of symmetry 51. The pattern segment 20 of the seventh pattern group 67 is the eighteenth pattern segment 671, meaning the seventh pattern group 67 includes multiple eighteenth pattern segments 671. All eighteenth pattern segments 671 protrude in a direction away from the first line of symmetry 110. The second ends of all eighteenth pattern segments 671 extend to the first line of symmetry 110.

[0188] In the seventh pattern strip group 67, the eighteenth pattern strip 671 that is furthest from the first symmetry line 110 is the outermost eighteenth pattern strip 671.

[0189] In the sixth pattern strip group 66, the second end of a portion of the seventeenth pattern strip 661 extends to the first symmetry line 110, and the second end of another portion of the seventeenth pattern strip 661 extends to the outermost eighteenth pattern strip 671 in the seventh pattern strip group 67.

[0190] In the first patterned stripe group 61, at least part of the first end of the twelfth patterned stripe segment 611 extends to the outermost eighteenth patterned stripe segment 671 in the seventh patterned stripe group 67.

[0191] like Figure 15 As shown, the seventh pattern stripe group 67 includes three eighteenth pattern stripe segments 671.

[0192] In this embodiment, the third pattern 50 has a preset boundary line 54.

[0193] It should be noted that the preset boundary line 54 is not an actual line, but a reference line used to illustrate the assumed tire tread pattern.

[0194] The first ends of multiple eighteenth pattern segments 671 extend to the preset boundary line 54; the first ends of multiple fifteenth pattern segments 641 extend to the preset boundary line 54.

[0196] Optionally, the default boundary line 54 is a straight line segment.

[0197] Optionally, the pattern unit 1000 in this embodiment forms a quadrilateral region.

[0198] In this embodiment, the preset pattern 10 also includes a nineteenth pattern segment 68, the first end of the nineteenth pattern segment 68 extends to the second end of the innermost thirteenth pattern segment 621 of the second pattern group 62, and the second end of the nineteenth pattern segment 68 extends to the second center line 52.

[0199] Optionally, the extension trajectory of the nineteenth pattern segment 68 is a straight line segment, and the extension trajectory of the nineteenth pattern segment 68 coincides with the third symmetry line 51.

[0200] In this embodiment, the tire tread includes one or more tread unit groups, and the multiple tread unit groups are distributed along a first direction; the tread unit group includes multiple tread units 1000 distributed along a second direction; the first direction and the second direction are set at an angle.

[0201] Optionally, the first direction and the second direction are perpendicular to each other.

[0202] Optionally, multiple tread pattern units are distributed along the circumference of the tire.

[0203] In this embodiment, the maximum vertical spacing between any two adjacent patterned strips 20 in a patterned strip group ranges from 0.1mm to 0.3mm, for example, 0.25mm.

[0204] It should be noted that when the patterned segment 20 is a convex segment 21, the maximum vertical spacing between the two patterned segments refers to the vertical spacing at the shorter base of the trapezoid and / or the apex of the triangle. When the patterned segment 20 is a concave segment, the maximum vertical spacing between the two patterned segments refers to the vertical spacing at the shorter base of the trapezoid and / or the apex of the triangle.

[0205] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0206] In the tire texture provided by this utility model, the tire texture includes one or more pattern units 1000; the pattern unit 1000 includes two pattern groups 100, and the two pattern groups 100 are arranged in a mirror symmetrical manner with respect to the first symmetry line 110.

[0207] The tread pattern group 100 includes two preset patterns 10, which are mirror-symmetrically arranged with respect to the second symmetry line 120; the second symmetry line 120 is perpendicular to the first symmetry line 110; both the first symmetry line 110 and the second symmetry line 120 are parallel to the outer surface of the tire.

[0208] The preset tread pattern 10 includes multiple tread segments 20. A first configuration of the tread segments 20 is as follows: the tread segments 20 are raised segments 21 protruding from the outer surface of the tire, with a groove 30 formed between any two adjacent raised segments 21. A second configuration of the tread segments 20 is as follows: the tread segments 20 are recessed segments recessed from the outer surface of the tire, with a protrusion formed between any two adjacent recessed segments.

[0209] The tire texture, or texture pattern, of this application forms multiple grooves 30 or sets multiple recessed segments to cause multiple reflections of incident light, thereby extending the propagation path of incident light within the texture and enhancing light absorption efficiency, thus reducing local brightness. In this way, the texture pattern area can be divided into bright and dark areas of different brightness, so that the texture pattern area can form a brightness contrast, thereby improving the recognizability and aesthetics of the texture pattern area.

[0210] The tire tread pattern of this application features: 1. The tread pattern area is divided into light and dark areas of different brightness (creating a brightness contrast). This difference in brightness between the light and dark areas forms a contrast in the marking area (the tread pattern area is used to form the marking area), effectively improving the recognizability of text and patterns within the marking area, as well as enhancing the overall aesthetics and recognizability of the tire. 2. The dark areas of the tire consist of tread patterns protruding from the tire base surface, effectively reducing the light reflection effect in this area, thus lowering its brightness and creating a brightness contrast between the light and dark areas. 3. The tread patterns forming the dark areas of the tire are all striped, effectively eliminating stress generated during tire rotation and deformation. This reduces the likelihood of cracks and breakage during tire use, extending the tire's lifespan. 4. Through groove structures on the side plates of the tire mold that match the tread patterns of the marking area, the light and dark areas of the tire marking area can be formed during tire vulcanization. 5. By arranging the lines, a specific effect is achieved in the pattern, solving the current problem of monotonous and unattractive tire sidewall patterns, and improving exhaust efficiency during tire vulcanization. 6. By setting the range of the above parameters, a better visual effect is ensured.

[0211] Alternatively, the marking area is usually located on the sidewall of the tire.
