[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) The high passability all-terrain tire of this utility model has a beveled edge on the tread block, which makes it contact the ground first when the tire rolls, so that the entire tread block can be embedded deeper into the ground. This can quickly destroy the surface structure of the ground, enhance the ground grip, and improve the starting grip and driving traction. It is especially suitable for soft road conditions such as mud, sand and snow.

[0017] (2) The transverse groove of the high pass all-terrain tire of this utility model adopts a groove bottom protrusion structure, which can apply elastic force and disturbance to embedded stones and other foreign objects when the tire rolls, making it difficult for foreign objects to be fixed in the groove, and using the centrifugal force of the tire to expel foreign objects, effectively avoiding tire damage, local wear and puncture risk caused by stone trapping, and further improving the tire's durability and stability in environments such as gravel and sand.

[0018] (3) Each tread of the high passability all-terrain tire of this utility model is provided with transverse steel strips, and the steel strips on the same tread block group have a continuous extension structure, which can generate slight elastic deformation when grounding, enhance the micro adhesion of the tire in wet, icy or snowy environments, and improve the tire's grip performance; through the cutting and stretching effect when the steel strips are deformed, the tire's ability to match the ground microstructure is significantly improved, the tire's braking performance and directional control force are improved, and slippage is prevented.

[0019] (4) The second middle tread block and the second shoulder tread block of the high passability all-terrain tire of this utility model are connected by a flexible connecting strip. Without weakening the independent meshing ability of the blocks, it provides additional lateral support force, so that the tread blocks can maintain overall stability when subjected to force deformation, and prevent tread tearing caused by uneven wear or shear deformation. Especially in high-speed or side slope driving conditions, it can enhance the integrity of the tire structure and fatigue resistance, and extend the tire service life.

[0020] (5) The first shoulder tread block of the high passability all-terrain tire of this utility model is set as a stepped structure, which can provide multi-level cutting contact points in soft road conditions, effectively improve the meshing force of the tire on the side slope or muddy edge area, and prevent side slip and burrowing; it also increases the lateral support area of ​​the tire during side rolling, enhances the edge anti-slip performance, and the exposed layer promotes mud to be thrown out when rolling, and has good self-cleaning and heat dissipation functions.

[0021] (6) The first and second central tread blocks of the high pass all-terrain tire of this utility model are provided with a chamfered structure in the central steel sheet to form an additional edge opening. When the tire rolls, it generates shear force, accelerates the discharge of mud accumulated between the steel sheets, avoids the tread blocks from being blocked by mud, and maintains effective contact between the tread and the ground. The chamfered edge forms a sharp discontinuous edge on the side of the steel sheet, which can also increase the biting point with soft ground, especially providing additional anti-skid resistance when subjected to lateral force.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "upper," "lower," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," and "third" may explicitly or implicitly include one or more of that feature. The term "longitudinal" refers to the direction in which the tire rolls; the term "lateral" refers to the direction perpendicular to the mid-surface of the tire.

[0034] This utility model provides a high passability all-terrain tire that combines high grip performance, high driving force and anti-stone trapping ability, making it especially suitable for harsh terrain. Figure 1 This is a schematic diagram of the tread pattern structure of a high-passability all-terrain tire according to an embodiment of the present invention. (Reference) Figure 1 As shown, this utility model discloses a high-pass all-terrain tire. The tire tread has a tread structure, which includes multiple first tread block groups and second tread block groups arranged obliquely along the circumference of the tire tread. The first and second tread block groups are staggered, and a tortuous transverse groove 100 is provided between the first and second tread block groups. One end of the transverse groove 100 has a V-shaped groove bottom protrusion 110, the height of which is 20% to 30% of the depth of the corresponding transverse groove 100. By using the groove bottom protrusion 110 structure, when the tire rolls, it can apply elastic force and agitation to embedded stones and other foreign objects, making it difficult for foreign objects to be fixed in the groove. The centrifugal force of the tire can also be used to expel foreign objects, effectively avoiding tire damage, local wear, and puncture risks caused by stone trapping, and further improving the tire's durability and stability in environments with gravel and sand. Each tread block in the first tread block group has beveled edges on both sides near the adjacent transverse groove 100. The angle of each bevel is 30° to 60°, and the length of each bevel is 10% to 25% of the side length of the corresponding tread block. The beveled edge structure forms a sharp ground-penetrating edge, which preferentially contacts the ground when the tire rolls, and can quickly break the surface structure of the ground. It is especially suitable for soft road conditions such as mud, sand and snow. It can produce a "blade cutting" effect in the initial contact stage, allowing the entire tread block to embed deeper into the ground, enhancing the ground grip and improving starting grip and traction.

[0035] The first tread block assembly of this high-pass all-terrain tire includes two first shoulder tread blocks 210 located on both sides of the tire and two first middle tread blocks 220 located between the two first shoulder tread blocks 210. A first longitudinal groove 230 with a V-shaped structure is provided between the first shoulder tread blocks 210 and the first middle tread blocks 220 to undertake the main mud and water drainage function. The depth of the first longitudinal groove 230 is greater than 80% of the maximum height of the adjacent tread blocks. A first oblique groove 240 is provided between the two first middle tread blocks 220. The first oblique groove 240 and the transverse groove 100 form a herringbone structure, forming a mud and water drainage path to assist the first longitudinal groove 230, significantly improving the mud and water drainage speed. (See attached diagram.) Figure 1 and attached Figure 2 As shown, the first central patterned block 220 has a second chamfer 222 and a third chamfer 223 respectively set on the edge of the patterned block near the adjacent transverse groove 100, and the first central patterned block 220 has a first chamfer 221 set on the edge of the pattern near the first oblique groove 240; see attached figure. Figure 1 and attached Figure 3 As shown, the first shoulder pattern block 210 has a fourth chamfer 211 and a fifth chamfer 212 respectively set on the two edges of the pattern block near the adjacent transverse groove 100; the first chamfer 221, the second chamfer 222, the third chamfer 223, the fourth chamfer 211, and the fifth chamfer 212 are all oblique chamfers of 30° to 60°, and the length of each chamfer is 10% to 25% of the side length of the corresponding pattern block. In one embodiment, the end of the first shoulder tread block 210 away from the first longitudinal groove 230 is a stepped structure with 2 to 3 steps. The width of each step is 0.5 to 1.5 mm, and the height difference between adjacent steps is 1 to 3 mm. This structure can provide multiple cutting contact points under soft road conditions, effectively improving the engagement force of the tire on the side slope or muddy edge area, and preventing sideslip and burrowing. At the same time, the stepped structure increases the lateral support area of ​​the tire during side rolling, enhances the edge anti-slip performance, and the exposed layers promote mud ejection during rolling, providing good self-cleaning and heat dissipation functions.

[0036] The second tread block assembly of this utility model high-pass all-terrain tire includes two second shoulder tread blocks 310 located on both sides of the tire, two second middle tread blocks 320 located between the two second shoulder tread blocks 310, and a central tread block 330 located between the two second middle tread blocks 320; a second longitudinal groove 350 is provided between the central tread block 330 and the adjacent second middle tread block 320, the second longitudinal groove 350 has a V-shaped structure and is used to undertake the main mud and water drainage function, the depth of the second longitudinal groove 350 is greater than 80% of the maximum height of the adjacent tread block; a second oblique groove 360 ​​is provided between the second middle tread block 320 and the adjacent second shoulder tread block 310, one end of the second oblique groove 360 ​​is connected to the adjacent transverse groove 100; see attached figure. Figure 1 and attached Figure 4 As shown, the central tread block 330 has a sixth chamfer 331 and a seventh chamfer 332 on each of its two edges near the adjacent lateral groove 100. Both the sixth chamfer 331 and the seventh chamfer 332 are bevel angles of 30° to 60°, and the length of each chamfer is 10% to 25% of the corresponding tread block's side length. The second central tread block 320 and the second shoulder tread block 310 are connected by a flexible connecting strip 340. The width of the connecting strip 340 is 2 to 5 mm, and its height is slightly lower than the minimum height of the adjacent tread blocks. The connecting strip 340 structure provides additional lateral support without weakening the independent meshing ability of the blocks, enabling the tread blocks to maintain overall stability under stress and deformation, preventing tread tearing caused by uneven wear or shear deformation. Especially under high-speed or side-slope driving conditions, it can enhance the integrity and fatigue resistance of the tire structure and extend tire life.

[0037] This utility model of a high-pass all-terrain tire features transverse steel strips on each tread pattern, with the steel strips on the same tread block group exhibiting a continuous extending structure. Each transverse steel strip has a width of 0.5–1 mm, a length of 10–30 mm, and an inclination angle of 15°–30°. This transverse steel strip structure allows for subtle elastic deformation upon contact with the ground, enhancing the tire's micro-adhesion in wet, icy, or snowy conditions. Through the cutting and tensile effects of the steel strip deformation, the tire's ability to adapt to the microstructure of the ground is significantly improved, enhancing braking performance and directional control, and preventing slippage. The transverse steel plates include a first shoulder steel plate 213 disposed on the first shoulder patterned block 210, a first middle steel plate 224 disposed on and penetrating the first middle patterned block 220, a second shoulder steel plate 311 disposed on the second shoulder patterned block 310, a second middle steel plate 321 disposed on and penetrating the second middle patterned block 320, and a central steel plate 333 disposed on and penetrating the central patterned block 330. The first middle steel plate 224 and the first shoulder steel plate 213 are connected by a first oblique groove 240 and a first longitudinal groove 230, forming a continuous extending structure. The central steel plate 333, the second middle steel plate 321, and the second shoulder steel plate 311 are connected by a second longitudinal groove 350 and a second oblique groove 360, forming a continuous extending structure. (See attached diagram.) Figure 5 As shown, the end of the first central steel sheet 224 near the first oblique groove 240 has a chamfered structure; see attached diagram. Figure 6As shown, the end of the second central steel sheet 321 furthest from the second longitudinal groove 350 has a chamfered structure. By setting the chamfer on the steel sheet, additional edge openings are formed, generating shear force when the tire rolls, accelerating the discharge of mud accumulated between the steel sheets, preventing the tread blocks from being blocked by mud, and maintaining effective contact between the tread and the ground; the chamfer also forms a sharp, discontinuous edge on the side of the steel sheet, which can increase the engagement point with soft ground, especially providing additional anti-skid resistance under lateral force.

[0038] The tread blocks of the first and second tread block groups of this high-pass all-terrain tire are interconnected by longitudinal, lateral, and oblique grooves. The longitudinal grooves are used for primary mud and water drainage, while the lateral and oblique grooves form auxiliary flow paths. The graded groove structure increases the number and guiding angle of the grooves, significantly improving the drainage and mud removal speed, preventing mud or gravel from accumulating and clogging the tread, effectively maintaining the tire's self-cleaning ability, and thus ensuring continuous grip and driving performance. Moreover, the cross arrangement of the lateral and longitudinal grooves also enhances the tire's anti-skid ability during driving. The chamfered corners on the tread blocks of the first and second tread block groups are staggered, forming sharp ground-penetrating edges. These corners preferentially contact the ground when the tire rolls, quickly disrupting the surface structure of the ground, especially suitable for soft road conditions such as mud, sand, and snow. A "knife-like cutting" effect is produced in the initial contact phase, allowing the entire tread block to embed deeper into the ground, enhancing ground grip and improving starting grip and traction.

[0039] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
