[0037] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments without conflict.

[0038] A tire pattern, comprising a tread, and further comprising:

[0039] A plurality of transverse grooves 1 are arranged transversely through the tread, and each transverse groove 1 is a wave-shaped structure with two opening directions in opposite directions to form an approximately S-shaped structure, wherein the two opening directions are respectively oriented toward the forward driving direction and the reverse driving direction of the tire.

[0040] A transverse pattern group is provided between each adjacent transverse groove 1; through the distribution design of a plurality of transverse grooves 1, the entire wheel surface is divided into a plurality of transverse pattern groups;

[0041] Each transverse pattern group is further designed as follows:

[0042] The middle longitudinal groove 4 runs through the middle of the transverse pattern group in the longitudinal direction; the middle of the middle longitudinal groove 4 is an equidistant portion with a constant width and an inclined structure, and the upper and lower ends of the middle longitudinal groove 4 are expanded diameter portions that expand from the inside to the outside;

[0043] The shoulder longitudinal groove 5 runs longitudinally through both sides of the transverse pattern group and presents a three-fold segment structure;

[0044] The transverse pattern group is divided into a central pattern block 2 and a shoulder pattern block 3 by a central longitudinal groove 4 and a shoulder longitudinal groove 5, and the central pattern block 2 and the shoulder pattern block 3 located on both sides of the tread center are arranged in a centrally symmetrical structure with the tread center as the axis.

[0045] Specifically, Figure 1 In the embodiment, the inner ends of the two central pattern blocks 2 located in the middle of the tread are both V-shaped, and the two V-shaped structures are staggered to form an equidistant portion and an expanded diameter portion. The pattern block structure at the middle pattern block 2 and the shoulder pattern block 3 adjacent to each other adopts a bite-type structure design, and the close ends of the two are in the form of a three-fold segment structure, so that the shoulder longitudinal groove 5 is a three-fold segment structure as a whole. The bite-type structure design can make the tire quickly squeeze out the mud attached to the shoulder longitudinal groove 5 by force extrusion during driving. By optimizing and improving the structural form of the middle pattern block 2 and the shoulder pattern block 3, a tiger claw-like hook-like structure is formed as a whole, thereby greatly improving the grip of the tire. The large through-type transverse groove 1 ensures its drainage performance, and the through-type structure also makes it easier for the attached mud to be thrown out.

[0046] In some embodiments, it also includes:

[0047] The stone-removing and mud-removing strips are located in the transverse groove 1 and are arranged along the setting direction of the transverse groove 1. The mud-removing performance of the transverse groove 1 is improved by arranging the stone-removing and mud-removing strips.

[0048] Specifically, the stone and mud removal strips include:

[0049] The middle groove protrusion 8 is arranged between the upper and lower adjacent middle pattern blocks 2; the middle groove protrusion 8 is composed of a long protrusion and short protrusions spaced at both sides of the long protrusion;

[0050] The shoulder groove protrusion 9 is arranged between the upper and lower adjacent shoulder pattern blocks 3; the shoulder groove protrusion 9 is composed of long protrusions and short protrusions alternately spaced.

[0051] By adopting the above structure, not only can the mud at the bottom of the groove be quickly discharged during off-road driving to avoid stones being trapped therein, but the lateral and longitudinal airflow impact can also be effectively blocked to reduce the noise generation, thereby improving the comfort performance of the tire.

[0052] In some embodiments, it also includes:

[0053] The middle steel sheet 6 is disposed on one side of the middle pattern block 2 and has a U-shaped structure, and both ends thereof are connected to the transverse groove 1 on one side of the middle pattern block 2;

[0054] The shoulder steel sheet 7 is transversely penetrated on the shoulder pattern block 3 and has a three-fold structure, and its inner end is connected with the shoulder longitudinal groove 5 and / or the transverse groove 1.

[0055] Specifically, both sides of the middle steel sheet 6 and the shoulder steel sheet 7 are provided with inwardly recessed annular grooves 10 to form a stepped structure.

[0056] The above steel sheet structure is used to improve the grip performance of the tire, and the annular groove 10 forms a widened structural design, which not only improves the drainage performance of the tire but also can more effectively discharge the heat generated by the tread.

[0057] Specifically, the equidistant portion is parallel to the inner section of the U-shaped structure in the middle steel sheet 6; the upper folding section of the three-fold structure in the shoulder longitudinal groove 5 is parallel to the outer section of the U-shaped structure in the middle steel sheet 6; the lower folding section of the three-fold structure in the shoulder longitudinal groove 5 is parallel to the middle folding section of the three-fold structure in the shoulder steel sheet 7.

[0058] Through the above structural design, the overall force on the tire is more balanced, and the tread support reliability during movement is higher.

[0059] In some embodiments, an inwardly recessed annular groove 10 is provided on the outer periphery of the middle pattern block 2 and the shoulder pattern block 3 to form a stepped structure. The design principle is the same as the widening design of the steel sheet, so it will not be repeated.

[0060] In some embodiments, the inner end of the shoulder pattern block 3 is provided with a multi-step groove 11 near the end corner of the transverse groove 1. Figure 2 As shown in FIG. 1 , two-level step grooves are specifically formed. The structural design of the multi-level step grooves is also to effectively prevent the stone clamping phenomenon and enhance the self-cleaning ability of the tread.

[0061] In some embodiments, the outer end surface of the shoulder pattern block 3 is in an inclined structure at the sidewall 14, and a concave anti-collision block 12 with a concave structure and a convex anti-collision block 13 with a convex structure are respectively provided at the upper end and inside thereof. The above arrangement effectively protects the sidewall and reduces the risk of scratches and damage to the sidewall.
