[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] Please refer to Figures 1 to 3 The present application provides a tire including a tread, wherein a pattern structure is provided on the tread, wherein the pattern structure includes: a first pattern block 1, which is arranged in the middle of the tread, and the first pattern blocks 1 are multiple, and the multiple first pattern blocks 1 are arranged at intervals along the circumferential direction of the tread; a first longitudinal groove 2, which is arranged on the side of the first pattern block 1, and the first longitudinal groove 2 extends along a broken line trajectory; a second longitudinal groove 3, which is arranged on a side of the first longitudinal groove 2 away from the first pattern block 1, and the second longitudinal grooves 3 are two, and the two second longitudinal grooves 3 are symmetrically arranged relative to the center line of the tread; wherein the extension directions of the two second longitudinal grooves 3 have an angle between them.

[0024] The tire provided herein includes a tread having a pattern structure, the pattern structure comprising a first tread block 1, a first longitudinal groove 2, and a second longitudinal groove 3. The first tread block 1 is disposed in the center of the tread, and the plurality of first tread blocks 1 are spaced apart along the circumferential direction of the tread. The first longitudinal groove 2 is disposed lateral to the first tread block 1 and extends along a zigzag path. The second longitudinal groove 3 is disposed on a side of the first longitudinal groove 2 away from the first tread block 1, and the plurality of second longitudinal grooves 3 are symmetrically arranged relative to the centerline of the tread. The two second longitudinal grooves 3 extend at an angle to each other. Specifically, the two second longitudinal grooves 3 are arranged in a V-shape relative to the center of the tread. The combination of the two grooves facilitates snow cutting and snow binding, enhancing the tire's grip on icy and snowy roads. The wider grooves also improve the tire's water and snow removal performance, enhancing the tire's braking ability on icy and snowy roads, and ensuring driving safety on icy and snowy roads.

[0025] Specifically, the tread structure further includes: a first transverse groove 4 disposed between two adjacent first blocks 1, with both ends of the first transverse groove 4 communicating with the first longitudinal groove 2. There are multiple first transverse grooves 4, spaced apart along the circumferential direction of the tread; adjacent first transverse grooves 4 are arranged symmetrically with respect to each other. Each first transverse groove 4 comprises a first groove segment 41 and a second groove segment 42, interconnected. The first groove segment 41 is inclined relative to the centerline of the tread, has a width of 2 cm to 3 cm, and a depth of 4 cm to 4.5 cm. The second groove segment 42 extends along the tread axis, has a width of 0.5 cm to 1.5 cm, and a depth of 0.5 cm to 1.5 cm. The first groove segment 41 includes a connecting end and a free end, the connecting end connected to the second groove segment 42. The depth of the first groove segment 41 gradually increases from the connecting end to the free end.

[0026] The first transverse grooves 4 are staggered up and down in opposite directions. The first pattern blocks 1 are divided into irregular hexagons by the first transverse grooves 4, and the two adjacent first pattern blocks 1 above and below form an approximate parallelogram. The width of the first groove segment 41 is preferably 2.5 cm, and the depth gradually transitions from 4 cm to 4.5 cm in the direction of the first longitudinal groove 2. The second groove segment 42 is 1 cm wide and 1 cm deep. This design of variable width and depth can ensure that the pattern blocks have sufficient rigidity. On the other hand, these transverse grooves also connect the tread patterns, making it easier for the tire to drain accumulated snow smoothly during driving, thereby improving the tire's grip performance.

[0027] In a specific implementation, the tread structure further includes: a second tread block 5 disposed between the second longitudinal groove 3 and the first longitudinal groove 2. Multiple second tread blocks 5 are provided, spaced apart along the circumferential direction of the tread; and third longitudinal grooves 6 disposed on the second tread block 5, obliquely disposed relative to the centerline of the tread. The third longitudinal grooves 6 divide the second tread block 5 into a first block 51 and a second block 52, effectively breaking up the water film and thereby improving grip.

[0028] Furthermore, the pattern structure also includes a second transverse groove 7, disposed between two adjacent second pattern blocks 5. The ends of the second transverse groove 7 are connected to the first longitudinal groove 2 and the second longitudinal groove 3, respectively. The width of the second transverse groove 7 gradually increases from the middle of the second transverse groove 7 to the ends of the second transverse groove 7. In a specific implementation, the second transverse groove 7 includes a third groove segment 71 and a fourth groove segment 72, which are interconnected. The third groove segment 71 is connected to the first longitudinal groove 2, and the fourth groove segment 72 is connected to the second longitudinal groove 3. The depth of the fourth groove segment 72 is half the depth of the third groove segment 71.

[0029] This variable width and depth setting not only ensures that the tread grooves are continuous and accumulated water can be discharged smoothly, thereby ensuring the tire's grip performance, but also ensures the rigidity of the first pattern block 1 and the second pattern block 5.

[0030] The tread structure also includes a third transverse groove 8, which is provided on the second tread block 5 and located on the side of the second tread block 5 closest to the first longitudinal groove 2. The third transverse groove 8 is provided at the bend of the first longitudinal groove 2. Adding this groove at the bend of the first longitudinal groove 2 not only improves snow removal on snowy roads but also generates friction with the snow in the groove, thereby enhancing the tire's braking performance.

[0031] In the examples provided in this application, Figure 1As shown, the tread structure further includes: a third tread block 9, disposed on a side of the second longitudinal groove 3 away from the first longitudinal groove 2. There are multiple third tread blocks 9, spaced apart along the circumferential direction of the tread; and fourth transverse grooves 10, disposed on the third tread block 9. A concave-convex structure 81 is provided on the groove wall of the third transverse groove 8. The concave portion of the concave-convex structure 81 increases the width of the third transverse groove 8. When the tire encounters a stone while driving on the road, the widening of the third transverse groove 8 by the concave-convex groove effectively ejects the stone, preventing the stone from being trapped in the shoulder groove and thus avoiding the impact on tire performance caused by the stone being trapped.

[0032] The tread structure further includes: a second tread block 5, disposed on the side of the first longitudinal groove 2 away from the first tread block 1; and a third tread block 9, disposed on the side of the second longitudinal groove 3 away from the first longitudinal groove 2. Steel sheets are provided on the first tread block 1, the second tread block 5, and the third tread block 9, respectively. These steel sheets are 3D steel sheets. Compared to conventional 2D steel sheets, the 3D steel sheets of this tread design enable finer cutting of the tread blocks, ensuring increased traction on snow while also increasing tread block rigidity and reducing block creep.

[0033] The following table compares the outdoor performance test results of the non-studded snow tire provided by this application with similar existing snow tires. Using a 205 / 55R16 tire as the test specification and evaluating the performance of the new tread pattern against the test data of existing tires, it can be seen that compared to the existing technology, the snow tire provided by this application has 22.7% improved snow braking performance, 12.5% ​​improved snow traction performance, 8.8% improved snow handling performance, 11.4% improved ice braking performance, and a 13.8% overall improvement in ice and snow performance. This superior ice and snow performance makes the tire safer and more reliable when driving on icy and snowy roads.

[0035] Specifically, the tire tread is provided with two inner serpentine first longitudinal grooves 2 arranged in the direction of tire rotation, and two outer inclined second longitudinal grooves 3. The outer inclined second longitudinal grooves 3 are designed with variable depth, and each is divided into a fifth groove segment 31 and a sixth groove segment 32. The four longitudinal grooves divide the tread from left to right into a shoulder pattern area A, a side pattern area B, a middle pattern area C, a side pattern area D, and a shoulder pattern area E.

[0036] Between two adjacent inner serpentine first longitudinal grooves 2 lies the central region C of the tread pattern, primarily composed of first transverse grooves 4 and first pattern blocks 1. The first transverse grooves 4 consist of inclined first groove segments 41 and horizontal second groove segments 42, staggered vertically and in opposite directions. The first pattern blocks 1 are divided into irregular hexagons by the first transverse grooves 4, with two adjacent first pattern blocks 1 forming a near-parallelogram. The first groove segment 41 is 2.5 cm wide, with a depth gradually increasing from 4 cm to 4.5 cm toward the first longitudinal groove 2. The second groove segment 42 is 1 cm wide and 1 cm deep. This variable width and depth design ensures sufficient rigidity for the pattern blocks. Furthermore, these transverse grooves provide full connectivity between the tread patterns, allowing the tire to more easily shed accumulated snow during driving, thereby improving its grip.

[0037] The side pattern areas B and D of this pattern are located between the adjacent inner serpentine first longitudinal grooves 2 and the outer inclined second longitudinal grooves 3. The second transverse grooves 7 are located between adjacent second tread blocks 5. The second transverse grooves 7 are composed of a third groove segment 71 and a fourth groove segment 72. The depth of the third groove segment 71 is half that of the fourth groove segment 72, and the width gradually widens from the inside to the outside. The second tread block 5 has an inclined third longitudinal groove 6, which divides the second tread block 5 into a first block 51 and a second block 52. This can effectively break up the water film and thus improve grip. A third transverse groove 8 is provided on the first block 51 near the first longitudinal groove 2. Adding this groove at the bend of the first longitudinal groove 2 not only improves the snow removal ability on snowy roads, but also generates friction with the snow in the groove, thereby improving the braking performance of the tire.

[0038] Shoulder pattern areas A and E are located outside the two outer, inclined second longitudinal grooves 3, respectively. A fourth transverse groove 10 is located between the upper and lower adjacent third pattern blocks 9. A concave-convex structure 81 is designed around the edge of the third pattern block 9. When the tire encounters a stone while driving on the road, the stepped grooves formed by the concave-convex structure widen the shoulder transverse grooves, effectively ejecting the stone and preventing it from being trapped in the shoulder pattern grooves, thereby minimizing the impact on tire performance.

[0039] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0040] 1. The tread design features two inner, serpentine first longitudinal grooves (2) that are broken-line grooves, and two outer, inclined second longitudinal grooves (3) that are arranged in a V-shape relative to the center of the tread. This combination of grooves facilitates snow cutting and binding, enhancing the tire's grip on icy and snowy roads. The wider grooves also improve the tire's water and snow removal capabilities.

[0041] 2. There is an inclined third longitudinal groove 6 on the second pattern block 5, which divides the second pattern block 5 into two parts, which can effectively break the water film and thus improve the wet performance on wading roads.

[0042] 3. The cross grooves of this pattern are designed with varying widths and depths to ensure sufficient rigidity of the pattern blocks. On the other hand, these cross grooves also connect the tread patterns, making it easier for the tire to drain snow during driving, thereby improving the tire's grip.

[0043] 4. The second tread block 5 is provided with a transverse groove near the turning point of the first longitudinal groove 2, which not only improves the snow-removing ability on snowy roads, but also generates friction with the snow in the groove, thereby improving the braking performance of the tire.

[0044] 5. Area A, formed by the intersection of the inner serpentine first longitudinal groove 2, the transverse grooves, and the central main transverse grooves, forms a cross-shaped, four-sided claw-like structure. This not only facilitates the formation of snow pillars with ice and snow on the road, but also consolidates the snow pillars within the grooves, reducing their deformation and movement, thereby increasing the shear force of the snow pillars and improving the tire's braking performance on ice and snow.

[0045] 6. The edge of the third tread block 9 is designed with stepped grooves arranged in a stepped manner. When the tire encounters stones while driving on the road, the stepped grooves widen the shoulder transverse grooves, which can effectively throw the stones out and prevent the stones from being clamped in the shoulder grooves, thus avoiding the impact on tire performance caused by the clamping of stones.

[0046] 7. Different types of 3D steel sheets are designed on the third tread block 9, the second tread block 5, and the first tread block 1. Compared with ordinary 2D steel sheets, the 3D steel sheets designed in this pattern can cut the tread blocks more finely and are more likely to damage icy and snowy roads. This can ensure that while increasing traction on snow, the rigidity of the tread blocks is increased and the creep of the tread blocks is reduced.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
