[0026] A tire pattern, comprising a central pattern group, a middle longitudinal groove 9, a middle pattern group, a shoulder longitudinal groove 10 and a shoulder pattern group arranged in sequence from inside to outside on the tread, and further comprising:

[0027] The central transverse groove 2 is in a three-fold segment structure with upper and lower folded openings, and is arranged through the central pattern group; and is composed of a central transverse groove middle section located in the central pattern group and a central transverse groove outer section located on both sides of the central transverse groove middle section; wherein the width of the central transverse groove middle section is smaller than the width of the central transverse groove outer section;

[0028] A first middle transverse groove 11 and a second middle transverse groove 12, and the two are respectively arranged through the middle pattern group on both sides of the central transverse groove 2;

[0029] The first middle transverse groove is composed of the inner end of the first middle transverse groove connected to the middle longitudinal groove 9 and the outer end of the first middle transverse groove connected to the shoulder longitudinal groove 10, and the width and depth of the inner end are respectively smaller than the width and depth of the outer end; specifically, the first middle transverse groove 11 is a three-fold segment structure with upper and lower folded openings, specifically, the inner section of the first middle transverse groove is connected to the middle longitudinal groove and is in a straight segment structure, the outer section of the first middle transverse groove is connected to the shoulder longitudinal groove and is in a V-shaped structure, and a step structure is formed by the depth difference between the two, which can be referred to Figure 2 The width of the second middle transverse groove is greater than the width of the outer section of the central transverse groove, and is specifically in the shape of a straight line segment structure.

[0030] The first shoulder transverse groove 15 and the second shoulder transverse groove 16 are V-shaped and penetrate the shoulder pattern groups outside the second middle transverse groove 12 and the first middle transverse groove 11 respectively, and the outer end widths of the two are different; the inner end width of the first shoulder transverse groove 15 is smaller than the outer end width of the first shoulder transverse groove 15, and is larger than the width of the second middle transverse groove 12; the inner end width of the second shoulder transverse groove 16 is smaller than the outer end width of the second shoulder transverse groove 16, and is larger than the outer end width of the first middle transverse groove 11.

[0031] The central transverse groove 2, the first middle transverse groove 11, the second middle transverse groove 12, the first shoulder transverse groove 15 and the second shoulder transverse groove 16 are different in overall structure and have corresponding distinguishing points, and cooperate with the central longitudinal groove 9 and the shoulder longitudinal groove 10 to form a connected overall structure, which forms a flow structure design that is narrow inside and wide outside in the lateral direction, so as to achieve the quietness of the tire on paved roads and the grip on unpaved roads respectively.

[0032] Its quietness is mainly achieved by generating different airflow disturbances through different transverse grooves, thereby avoiding the same frequency of noise generated by each transverse groove, thereby avoiding the problem of the sound spectrum generated by the periodic contact between the pattern block and the paved road surface being superimposed and causing the noise to become louder.

[0033] Its grip is mainly achieved through a connected structure that is narrow inside and wide outside, so that mud and accumulated water can be discharged more quickly, thereby ensuring stable ground contact with the tire and providing the tire with more emphasized grip for driving on unpaved roads.

[0034] In some embodiments, the middle longitudinal groove 9 and the shoulder longitudinal groove 10 are both continuous multi-fold line structures and the fold line angle of the middle longitudinal groove 9 is smaller than the fold line angle of the shoulder longitudinal groove 10. The width of the middle longitudinal groove 9 is smaller than the width of the shoulder longitudinal groove 10, and the depth of the middle longitudinal groove 9 is greater than the depth of the shoulder longitudinal groove 10. The tread is divided into 5 pattern groups by the middle longitudinal groove 9 and the shoulder longitudinal groove 10. The parameters of the middle longitudinal groove 9 and the shoulder longitudinal groove 10 are designed to form a distinct longitudinal groove structure, so that the tire has better forward performance and better noise and comfort when used on paved roads; and the wider width can also help the tire discharge silt and accumulated water faster, ensuring stable grounding of the tire. At the same time, the deviation of the fold line angle range of the two can give the tire a certain traction and grip on muddy roads, thereby improving the passability of the tire.

[0035] In some embodiments, the central pattern group is divided by a central transverse groove 2 to form a plurality of alternately arranged first central pattern blocks 1-1 and second central pattern blocks 1-2; the first central pattern blocks 1-1 and the second central pattern blocks 1-2 are respectively provided with a second central steel sheet 4 and a first central steel sheet 3 which are arranged transversely and through, and the first central steel sheet 3 and the second central steel sheet 4 are not arranged in parallel.

[0036] Specifically, the first central steel sheet 3 and the second central steel sheet 4 are in a three-fold section structure with upper and lower folded openings, the middle section length of the first central steel sheet 3 is smaller than the two end lengths of the first central steel sheet 3, and the middle section length of the second central steel sheet 4 is larger than the two end lengths of the second central steel sheet 4.

[0037] In some embodiments, the middle pattern group is separated by the alternating first middle transverse grooves 11 and the second middle transverse grooves 12 to form a plurality of alternatingly arranged first middle pattern blocks 5 and second middle pattern blocks 6; the first middle pattern blocks 5 and the second middle pattern blocks 6 are both provided with the first middle steel sheets 7 and the second middle steel sheets 8 which are arranged transversely and non-through.

[0038] Specifically, the first middle steel sheet 7 and the second middle steel sheet 8 are both in a three-fold segment structure with upper and lower folded openings. The inner end of the first middle steel sheet 7 is not connected to the middle longitudinal groove 9, and the outer end of the first middle steel sheet 7 is connected to the shoulder longitudinal groove 10; the inner end of the second middle steel sheet 8 is connected to the middle longitudinal groove 9, and the outer end of the second middle steel sheet 8 is not connected to the shoulder longitudinal groove 10.

[0039] In some embodiments, the shoulder pattern group is separated by the alternating first shoulder transverse grooves 15 and the second shoulder transverse grooves 16 to form a plurality of alternatingly arranged first shoulder pattern blocks 13 and second shoulder pattern blocks 14; the first shoulder pattern blocks 13 and the second shoulder pattern blocks 14 are respectively provided with the first shoulder steel sheets 17 and the second shoulder steel sheets 18, and the first shoulder steel sheets 17 and the second shoulder steel sheets 18 are not arranged in parallel.

[0040] Specifically, the first shoulder steel sheet 17 and the second shoulder steel sheet 18 are both in a three-fold segment structure with upper and lower folded openings, and the inner ends of the two are in conduction with the middle longitudinal groove 9.

[0041] In the above embodiment, by providing corresponding steel sheets, the rigidity of the block pattern can be weakened, the ground contact mark can be improved, the grip and traction performance can be enhanced, the comfort and noise can be improved, and the heat can be effectively dissipated to prevent heat accumulation.

[0042] At the same time, the steel sheets of the first central pattern block 1-1 and the second central pattern block 1-2 located in the center, the steel sheets of the first central pattern block 5 and the second central pattern block 6 located in the middle, and the steel sheets of the first shoulder pattern block 13 and the second shoulder pattern block 14 located on the sides have different structures, and there are corresponding differences in the horizontal angles, the length settings, or the connecting structures. As a result, when the tire is squeezed, the difference in the strength of the pattern blocks caused by the steel sheets themselves causes certain differences in the deformation, so as to avoid the same frequency phenomenon when squeezing the internal air and increase the noise decibels.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
