[0024] In order to solve the problem that poor water drainage or snow removal performance of existing tires affects the safety of driving on snow, this application provides a tire tread structure and a tire having the same.

[0025] like Figure 1 and Figure 2As shown, the tire tread structure includes a plurality of first groove groups 1 and a plurality of second groove groups 8 spaced apart along the circumference of the tire. Each first groove group 1 includes a first main groove 11 and a second main groove 12. The first main groove 11 extends from the first shoulder 71 of the tire to the center surface CS of the tread structure, and the second main groove 12 extends from the first shoulder 71 to a position having a first distance from the center surface CS. Along the direction from the first shoulder 71 to the center surface CS, the angle between the extending direction of the first main groove 11 and / or the second main groove 12 and the center surface CS gradually decreases.

Along the direction from the second tire shoulder 72 to the center surface CS, the angle between the extension direction of the third main groove 81 and / or the fourth main groove 82 and the center surface CS gradually decreases. Multiple first groove groups 1 and multiple second groove groups 8 are located on both sides of the center surface CS; the multiple first groove groups 1 and multiple second groove groups 8 are staggered along the circumference of the tire.

[0030] In this embodiment, along the direction from the second shoulder 72 to the center plane CS, the angle between the extension directions of the third main groove 81 and the fourth main groove 82 and the center plane CS gradually decreases.

[0031] like Figure 1 As shown, the tire tread structure also includes a first secondary groove 21 and a second secondary groove 22.

[0032] In this embodiment, the first secondary ditch 21 connects to the adjacent first main ditch 11 and second main ditch 12, forming a snow drainage channel between the main ditches. The second secondary ditch 22 connects to the adjacent first main ditch 11 and second main ditch 12 to form a continuous cross-shaped snow drainage channel.

In this way, the aforementioned settings for depth difference and angle can maintain good drainage performance and grip during tire operation, providing drivers with a safer and more stable driving experience.

[0034] In this embodiment, the depth of the first main groove 11 is greater than the depth of the first secondary groove 21, with a depth difference Δh1 of 3.2 mm; the depth of the first main groove 11 is greater than the depth of the second secondary groove 22, with a depth difference Δh2 of 3.2 mm; the depth of the second main groove 12 is greater than the depth of the first secondary groove 21, with a depth difference Δh3 of 3.2 mm; and the depth of the second main groove 12 is greater than the depth of the second secondary groove 22, with a depth difference Δh4 of 3.2 mm. The first secondary groove 21 is set at an angle A = 40° with the center plane CS, and the second secondary groove 22 is set at an angle B = 3° with the center plane CS.

Optionally, the ratio of the total grounding area of ​​the first patterned block 31, the second patterned block 32, the third patterned block 33, the fourth patterned block 34, and the fifth patterned block 35 to the total area within its grounding width is 0.62, 0.65, 0.68, 0.70, or 0.72.

[0060] like Figure 1 As shown, the tire tread structure also includes studs 6, which are disposed on at least one of the first tread block 31, the second tread block 32, the third tread block 33, the fourth tread block 34, and the fifth tread block 35. In this way, by rationally distributing the studs 6, not only is strong grip provided on icy and snowy roads, but noise and vibration are also reduced on dry roads, providing drivers with a comfortable and safe driving experience. At the same time, the above arrangement allows for more flexible placement of the studs 6 to meet different usage needs and working conditions, and also improves the processing flexibility of workers.

[0061] In this embodiment, studs 6 are provided on the first tread block 31, the second tread block 32, the third tread block 33, the fourth tread block 34, and the fifth tread block 35. In this way, the staggered studs 6 improve the tire's grip performance while ensuring the overall rigidity of the tread, allowing users to drive more safely on icy and snowy roads.

[0062] Optionally, the tread structure is provided with nail holes, and the nails 6 are inserted into the nail holes, with knurling around the nail holes. In this way, the knurling can isolate snow accumulation, allowing the nails 6 to fully function.

[0063] Optionally, the total number of studs 6 on the fourth tread block 34 and / or the fifth tread block 35 is 'a', and the total number of studs 6 on the first tread block 31 and / or the second tread block 32 and / or the third tread block 33 is 'b', satisfying: 0.9b ≤ a ≤ 0.95b. This reasonable number and distribution of studs 6 allows the tire to drive more safely on icy and snowy roads.

[0064] In this embodiment, the fourth patterned block 34 and the fifth patterned block 35 are each provided with rivets 6, and the total number is a. The first patterned block 31, the second patterned block 32 and the third patterned block 33 are each provided with rivets 6, and the total number is b, and a = 0.95b is satisfied.

[0065] It should be noted that the total number of rivets 6 set on the fourth patterned block 34 and / or the fifth patterned block 35 is 'a', and the total number of rivets 6 set on the first patterned block 31 and / or the second patterned block 32 and / or the third patterned block 33 is 'b'. The value relationship between 'a' and 'b' is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, 'a' = 0.92b or 'a' = 0.945b.

[0066] like Figure 1 and Figure 2 As shown, the insert 6 includes a head 61, a body 62, and an insert 63 connected in sequence. The insert 63 extends into at least one of the first tread block 31, the second tread block 32, the third tread block 33, the fourth tread block 34, and the fifth tread block 35. This arrangement of the insert 6 ensures traction and braking performance on icy and snowy roads, while maintaining its effectiveness during wear. It is suitable for winter driving and icy and snowy roads, providing drivers with a safe and reliable driving experience on these surfaces. Furthermore, this arrangement simplifies the structure of the insert 6, making it easier to manufacture and implement, thus reducing manufacturing costs and complexity.

[0067] In this embodiment, the insert 63 extends into the nail hole, while the nail head 61 and nail body 62 are located outside the nail hole.

[0068] Optionally, the diameter d1 of the nail head 61 satisfies: 3.5mm ≤ d1 ≤ 4.5mm; the nail body 62 is cylindrical and its diameter d2 satisfies: 2.0mm ≤ d2 ≤ 3.0mm; the height h of the nail body 62 satisfies: 8.5mm ≤ h ≤ 11.5mm. This configuration allows for greater flexibility in determining the values ​​of the nail head 61 diameter d1, the nail body 62 diameter d2, and the nail body 62 height h, thus meeting different usage requirements and working conditions and improving the processing flexibility of workers.

[0069] In this embodiment, the diameter d1 of the nail head 61 is 3.8 mm, the diameter d2 of the nail body 62 is 2.4 mm, and the height h of the nail body 62 is 10 mm.

[0070] It should be noted that the diameter d1 of the nail head 61 is not limited to this value and can be adjusted according to working conditions and usage requirements. Optionally, the diameter d1 of the nail head 61 can be 3.6mm, 4.0mm, or 4.2mm.

[0071] It should be noted that the diameter d2 of the nail body 62 is not limited to this value and can be adjusted according to working conditions and usage requirements. Optionally, the diameter d2 of the nail body 62 can be 2.2mm, 2.5mm, 2.6mm, or 2.8mm.

[0072] It should be noted that the value of the height h of the nail body 62 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the height h of the nail body 62 can be 8.8mm, 9.0mm, 9.5mm, 9.8mm, 10.5mm, 10.8mm, 11.0mm, or 11.4mm.

[0073] like Figure 1 As shown, each first groove group 1 further includes a first groove 13 communicating with the first main groove 11. The first groove 13 and the first main groove 11 are located on opposite sides of the center surface CS and are set at an acute angle. And / or, each second groove group 8 further includes a second groove 83 communicating with the third main groove 81. The second groove 83 and the third main groove 81 are located on opposite sides of the center surface CS and are set at an acute angle. Thus, the above-mentioned arrangement of the first groove 13 and the second groove 83 increases the tire's grip, especially on wet and muddy roads, effectively removing water and mud from the tire surface, making it suitable for driving in the rainy season and on muddy roads, providing the driver with better handling stability and anti-skid performance. At the same time, the above-mentioned arrangement of the first groove 13 and the second groove 83, while ensuring crown rigidity, helps the tire quickly cut through the snow layer when in contact with the road surface. The staggered arrangement of the main grooves thus has a stronger snow column cutting force, improving the ability to grip, compact, and expel snow, achieving excellent snow performance.

[0074] In this embodiment, both the first groove 13 and the second groove 83 are located at the center surface CS.

[0075] like Figure 1 As shown, the tire tread structure also includes a first steel sheet 41, a second steel sheet 42, and a third steel sheet 43. The first steel sheet 41 is disposed on the first tread block 31, the second steel sheet 42 is disposed on the second tread block 32 and / or the third tread block 33, and the third steel sheet 43 is disposed on the fourth tread block 34 and / or the fifth tread block 35. Thus, the aforementioned arrangement of the first steel sheet 41, the second steel sheet 42, and the third steel sheet 43 enhances the tire's wear resistance and cut resistance, effectively extending the tire's service life.

[0076] In this embodiment, the first steel sheet 41, the second steel sheet 42, and the third steel sheet 43 are all zigzag steel sheets. These zigzag steel sheets cut each tread block into smaller fragments, increasing the tire's grip performance on snow. Simultaneously, the zigzag steel sheets make the tread blocks mesh more tightly, increasing the friction between the tire and the icy / snowy road surface, thus enhancing snow grip and improving passability and safety on icy / snowy roads. The wider spacing between the steel sheets ensures the rigidity of the shoulder tread blocks while also providing the tire with grip and handling performance on icy / snowy roads.

[0077] In this embodiment, the bending angle of the third steel sheet 43 is consistent with the contour of the tire.

[0078] Optionally, the first steel sheet 41 is perpendicular to the tire's driving direction, the second steel sheet 42 is set at an angle E with the center plane CS, and satisfies: 50°≤E≤70°; the third steel sheet 43 extends in the same direction as the fourth tread block 34 and / or the fifth tread block 35.

[0079] In this embodiment, the angle E between the second steel sheet 42 and the center plane CS is 60°. The extension direction of the third steel sheet 43 is consistent with that of the fourth patterned block 34 and the fifth patterned block 35.

[0080] It should be noted that the angle E between the second steel sheet 42 and the center plane CS is not limited to this value and can be adjusted according to working conditions and usage requirements. Optionally, the angle E between the second steel sheet 42 and the center plane CS can be 55°, 65°, or 68°.

[0081] Optionally, there are multiple first steel plates 41, spaced apart along the circumference of the tire, with a distance between adjacent first steel plates 41 greater than or equal to 2.5 mm and less than or equal to 2.8 mm; and / or, there are multiple second steel plates 42, spaced apart along a preset direction, with a distance between adjacent second steel plates 42 greater than or equal to 2.5 mm and less than or equal to 2.8 mm, and the preset direction forms a preset angle with the center plane CS; and / or, there are multiple third steel plates 43, spaced apart along the circumference of the tire, with a distance between adjacent third steel plates 43 greater than or equal to 3.2 mm and less than or equal to 4.0 mm. In this way, the closely arranged steel plates increase tire contact patch engagement, shorten braking distance, and improve the tire's traction on snow.

[0082] Optionally, the tire tread structure also includes drainage grooves 51, shoulder sipes 52, and triangular grooves 53. The drainage grooves 51 connect to the lateral grooves on the first tire shoulder 71 and / or the second tire shoulder 72. The shoulder sipes 52 are located on the fourth tread block 34 and / or the fifth tread block 35. The triangular grooves 53 are located close to the first tire shoulder 71 and / or the second tire shoulder 72 and are inclined. In this way, the uneven arrangement of the drainage grooves 51 and the shoulder sipes 52 can assist the lateral grooves in quickly dissipating water and improve drainage capacity. The triangular grooves 53 increase the snow removal capacity of the tire shoulder and increase grip on icy and snowy roads.

[0083] Optionally, the first steel sheet 41 is evenly distributed along the side length of the first patterned block 31 to divide the first patterned block 31 into several first tire blocks.

[0084] Optionally, the second steel sheet 42 is evenly distributed along the side length of the second patterned block 32 to divide the second patterned block 32 into several second tire blocks.

[0085] Optionally, the second steel sheet 42 is evenly distributed along the side length of the third patterned block 33 to divide the third patterned block 33 into several third tire blocks.

[0086] Optionally, the third steel sheet 43 is evenly distributed along the side length of the fourth patterned block 34 to divide the fourth patterned block 34 into several fourth tire blocks.

[0087] Optionally, the third steel sheet 43 is evenly distributed along the side length of the fifth patterned block 35 to divide the fifth patterned block 35 into several fifth tire blocks.

[0088] Optionally, the spacing and radius of curvature of the plurality of third steel plates 43 disposed on the fourth patterned block 34 and / or the fifth patterned block 35 are greater than the spacing and radius of curvature of the remaining steel plates.

[0089] This application also provides a tire (not shown) including the tire tread structure described above.

[0090] In this embodiment, the tire noise level is 71 dB, which is considered a low-noise tire.

[0091] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0092] The tire tread structure includes a plurality of first groove groups spaced apart circumferentially along the tire and a plurality of second groove groups spaced apart circumferentially along the tire. Each first groove group includes a first main groove and a second main groove. The first main groove extends from the first shoulder of the tire to the center surface CS of the tread structure, and the second main groove extends from the first shoulder to a position at a first distance from the center surface CS. Along the direction from the first shoulder to the center surface CS, the angle between the extension direction of the first main groove and / or the second main groove and the center surface CS gradually decreases. Each second groove group includes a third main groove and a fourth main groove. The third main groove extends from the second shoulder of the tread structure to the center surface CS, and the fourth main groove extends from the second shoulder to a position at a second distance from the center surface CS. Along the direction from the second shoulder to the center surface CS, the angle between the extension direction of the third main groove and / or the fourth main groove and the center surface CS gradually decreases. The system comprises multiple first groove groups and multiple second groove groups located on either side of the center surface CS; these groups are staggered along the circumference of the tire. This arrangement of the first and second groove groups increases the snow or water drainage area, ensuring timely removal of accumulated water and snow, preventing wheel slippage, improving handling stability on icy and snowy roads, and enhancing driving safety on snow. This solves the problem of poor snow or water drainage performance in existing tires, which negatively impacts driving safety on snow.
