This situation is particularly obvious in off-road vehicles. Off-road vehicles often travel on different terrains, such as rocks, gravel, and mud. Therefore, how to ensure the controllability of off-road vehicles under various extreme road conditions is one of the urgent problems to be solved at present. Summary of the Utility Model

[0033] 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.

[0034] A tire pattern comprises a middle pattern group located in the middle of the tread and side pattern groups located on both sides of the tread, wherein the middle pattern group comprises:

[0035] A plurality of first middle transverse grooves 1 are arranged transversely through the middle pattern group and along the movement direction of the tire; specifically, the first middle transverse groove 1 is an arc-shaped structure with upper and lower openings, and similarly, it can also be a broken line structure, that is, it can satisfy the upper and lower opening structure form, thereby ensuring its grip performance.

[0036] A pair of second middle transverse grooves 3 are symmetrically centered on the central axis of the tread on the middle pattern group and are located between every two adjacent first middle transverse grooves 1; the outer end of each second middle transverse groove 3 communicates with the side longitudinal groove 8 between the middle pattern group and the side pattern group, and the inner end of each second middle transverse groove 3 is located inside the middle pattern group; specifically, the second middle transverse groove 3 is in an arc-shaped structure; it can also be in a multi-folded segment structure, and its width can adopt a structure with a reduced diameter from the outside to the inside to form a claw state.

[0037] The second middle longitudinal groove 4 is communicatively arranged between a pair of second middle transverse grooves 3; through the above-mentioned communication method, a communicative structure design is carried out for the second middle transverse grooves 3 on both sides. Specifically, the second middle longitudinal groove 4 and the second middle transverse groove 3 it communicates with are in an H-shaped structure. That is to say, the communication point between the second middle longitudinal groove 4 and the second middle transverse groove 3 is not located at the inner end position of the second middle transverse groove 3.

[0038] A pair of first middle longitudinal grooves 2 are longitudinally and symmetrically arranged through the middle pattern group along the central axis of the tread and pass through each first middle transverse groove 1 and second middle transverse groove 3. Specifically, the first middle longitudinal groove 2 located between the upper and lower adjacent second middle transverse grooves 3 is in a V-shaped structure or an arc-shaped structure with an opening facing the outside. As Figure 1 , the first middle longitudinal grooves 2 located between adjacent second middle transverse grooves 3 are arranged in a staggered manner up and down.

[0039] Through the distribution of the above-mentioned structural settings, the middle pattern group is divided by the first middle transverse groove 1, the second middle transverse groove 3, the second middle longitudinal groove 4, and the first middle longitudinal groove 2 to form a middle second tread block 6 in the middle of the tread and middle first tread blocks 5 and middle third tread blocks 7 on both sides thereof, and the shapes, sizes, and areas of the three are all inconsistent.

[0040] Among them, the upper and lower adjacent middle second tread blocks 6 between adjacent first middle transverse grooves 1 are integrally in an S-shaped structure.

[0041] The self-locking tread block structure is realized through the S-shaped structure formed by the upper and lower combinations, which is beneficial to the engagement between the tread blocks, thereby ensuring its rigid strength and ensuring its grip performance. At the same time, the connected through-groove structure can effectively discharge mud and sand, prevent the tread from being blocked, ensure that the tire always maintains the best grip ability, and utilize the mutual engagement between the tread blocks to self-clean and extrude the sand and gravel under the action of the deformation and rotation of the tread blocks.

[0042] Since the shapes, sizes and areas of the tread blocks are not consistent, the noises they generate can be further differentiated by using a variable pitch arrangement, thereby disrupting the periodic resonance of the sound waves and effectively reducing the noise. Through the above structure and the adjustment of the arrangement distance of the tread blocks, the noise level of the tire in various terrains has been significantly reduced, especially when driving on highways, the noise control effect is particularly obvious.

[0043] At the same time, in conjunction with the above-mentioned pattern block structure, corresponding steel sheets are further arranged on the top to effectively disperse the impact force when the tire contacts the ground, absorb part of the energy, and reduce the spread of noise; and further reduce the rigidity of the tread, so that the tire produces less vibration when it contacts the ground, reducing noise. At the same time, the multi-layered steel sheets effectively help the tire cut through the water film, drain the road surface water, and provide a shorter wet braking distance.

[0044] Specifically, the steel sheet of the middle pattern group is arranged as follows, including:

[0045] The second steel sheet 14 and the fourth steel sheet 16 are respectively provided through the middle second pattern block 6 and the middle first pattern block 5, and are in a continuous multi-fold segment structure as a whole;

[0046] The first steel sheet 13 is provided through the second middle pattern block 6;

[0047] The fifth steel sheet 17 and the third steel sheet 15 are semi-penetratingly arranged on the middle third pattern block 7 and the middle first pattern block 5 respectively;

[0048] The fifth steel sheet 17, the first steel sheet 13 and the third steel sheet 15 are in a continuous multi-fold segment structure as a whole;

[0049] The eighth steel sheet 18 is semi-penetratingly arranged on the third middle pattern block 7 , and its outer end is connected to the side longitudinal groove 8 .

[0050] Furthermore, two ends of the second steel sheet 14 are respectively connected to the side longitudinal groove 8 and the second middle transverse groove 3 .

[0051] The arrangement, shape, length and size of the steel sheet on each tread block are different. The central position adopts a through-type structure design, which can more effectively disperse the impact force when the tire contacts the ground, reduce the strength of the tread block in the center, and also cooperate with the S-shaped self-locking structure to ensure its support. The side tread blocks on both sides do not have a self-locking structure, and a combination of semi-through and through-type is used to adjust the rigidity of the side tread blocks. The second steel sheet 14 is also arranged to divide the middle second tread block 6 to avoid tearing the middle second tread block 6 during the force process.

[0052] Based on the above solution, the following structural design is adopted for the further side pattern group, specifically including:

[0053] Multiple shoulder transverse grooves are transversely and continuously arranged in the side pattern group and are arranged along the tire movement direction. The side pattern group is divided into multiple side pattern blocks 12 by the shoulder transverse grooves; each shoulder transverse groove includes a side narrow transverse groove 9 and a side wide transverse groove 10. The side narrow transverse groove 9 is close to the inner side of the tread, and the width of the side narrow transverse groove 9 is smaller than the width of the side wide transverse groove 10; an expansion opening 11 with a reduced diameter structure from the inner side of the tread to the outer side of the tread is provided at the inner end of the side narrow transverse groove 9; the width of the smallest end of the expansion opening 11 is greater than the width of the side narrow transverse groove 9.

[0054] The shoulder transverse grooves adopt a combination of narrow and thick pattern grooves to improve the overall continuity of the shoulder pattern blocks. When the tire is running, the force linkage of the shoulder pattern blocks is better, which can improve the dry grip. At the same time, when the air flow in the side longitudinal groove 8 is transmitted to the side narrow transverse groove 9, the flow velocity of the air flow can be reduced, so that the air flow will not be discharged quickly through the shoulder pattern grooves, reducing the occurrence probability of sharp noise. And in order to ensure the guiding effect of the air flow, an expansion opening 11 with a reduced diameter structure from the inner side of the tread to the outer side of the tread is provided at the inner end of the side narrow transverse groove 9; the width of the smallest end of the expansion opening 11 is greater than the width of the side narrow transverse groove 9 to ensure the guiding property of the air flow.

[0055] Further, a corresponding steel sheet structure is provided on the side pattern block 12 to adjust the corresponding performance of the side pattern group, specifically including:

[0056] The ninth steel sheet 19 and the tenth steel sheet 20 are both in a three-fold segment structure and are alternately arranged on the side pattern block 12;

[0057] The inner end of the ninth steel sheet 19 is communicated with the side longitudinal groove 8, and the inner end of the tenth steel sheet 20 is not communicated with the side longitudinal groove 8.

[0058] As Figure 1 shown, specifically, there are 2 ninth steel sheets 19, and there is 1 tenth steel sheet 20 and it is located between the two ninth steel sheets 19. The inner ends of the two ninth steel sheets 19 respectively form a coherent overall structure with the corresponding steel sheet structure, so that after the pattern block is cut by the steel sheet, the force is more uniform, thereby improving its wear resistance and preventing local excessive wear.

[0059] An all-terrain tire includes: the tire pattern as in any one of the above embodiments.

[0060] Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
