Description

Technical Field

[0001] The present invention relates to the technical field of all-terrain tires, and in particular to an all-terrain tire suitable for all seasons. Background Art

[0002] All-terrain tires are tires that combine off-road and on-road performance, designed to meet the needs of off-road enthusiasts and drivers who seek adaptability to multiple road conditions. The design of all-terrain tire patterns usually uses deeper and wider grooves to ensure traction on muddy and gravel roads. However, the climate in North America is changeable, with distinct four seasons and winter is often accompanied by heavy snowfall. Existing all-terrain tires cannot safely drive on wet and slippery roads and icy roads.

[0003] Although all-terrain tires can provide good performance in a variety of road conditions, their performance on slippery roads and icy and snowy roads is not as good as that of tires designed for wet and snowy conditions. Their deep and wide grooves may affect the drainage performance between the tire and the ground, reducing the tire's grip on wet ground. Therefore, the purpose of the present invention is to provide an enhanced tire pattern structure that takes into account all seasons and all terrains. Through the unique groove and tread block shape design, the tire's grip and safety in snowy conditions are significantly improved, and an all-terrain tire suitable for all seasons is proposed. Summary of the Invention

[0004] The present invention provides an all-terrain tire suitable for all seasons, which solves the problem of poor grip and safety of all-terrain tires in the prior art on wet and slippery roads and icy and snowy roads.

[0005] In one aspect, an all-terrain tire suitable for all seasons includes a tire body, wherein a tread of the tire body is provided with shoulder pattern blocks, side pattern blocks, and center pattern blocks; The shoulder pattern blocks include a first long pattern block and a first short pattern block, and the edge pattern blocks include a second long pattern block and a second short pattern block; The first long pattern block, the first short pattern block, the second long pattern block, the second short pattern block and the center pattern block are all provided with extremely fine auxiliary grooves, and the extremely fine auxiliary grooves are arranged in a V shape; A groove cycle is provided between every two of the side pattern blocks located in the circumferential direction of the central pattern block, and the central pattern block and the corresponding two groups of side pattern blocks form a pattern structure.

[0006] On the other hand, the first long blocks and the first short blocks are alternately arranged in the circumferential direction of the tire body, and the second long blocks and the second short blocks are alternately arranged in the circumferential direction of the tire body.

[0007] On the other hand, each group of the shoulder pattern blocks corresponds to a group of the edge pattern blocks.

[0008] On the other hand, the shoulder pattern blocks and the side pattern blocks are arranged in the transverse direction of the tire body, and the side pattern blocks are staggered in the circumferential direction of the tire body.

[0009] On the other hand, the central pattern block is arranged in a groove cycle, and the pattern structure is propeller-shaped.

[0010] On the other hand, the center pattern block located in the transverse direction of the tire body is provided at the center of the two groups of the side pattern blocks.

[0011] On the other hand, the central pattern block forms an angle α with the transverse direction of the tire body, and the angle α is between 25° and 40°.

[0012] On the other hand, the number of the very fine auxiliary grooves distributed on the first long pattern block, the first short pattern block, the second long pattern block, the second short pattern block, and the center pattern block is up to root, and the connection parts of the very fine auxiliary grooves form an angle β, and the angle β is formed between 120° and 180°.

[0013] On the other hand, the edge portions of the first long pattern block, the first short pattern block, the second long pattern block, the second short pattern block, and the center pattern block are all provided with pattern block edge structures of different depths, and the pattern block edge structures include a first stepped pattern block, a second stepped pattern block, a third stepped pattern block, a fourth stepped pattern block, and a fifth stepped pattern block.

[0014] On the other hand, the thickness of the first stepped pattern block, the second stepped pattern block, the third stepped pattern block, the fourth stepped pattern block, and the fifth stepped pattern block is in the range of 0 mm to 4 mm.

[0015] The present invention provides an all-season all-terrain tire, which can improve the drainage efficiency of the main grooves of the tire body by arranging extremely fine secondary grooves, thereby improving the grip of the tire body on wet and slippery roads.

[0016] The present invention provides an all-terrain tire suitable for all seasons. By providing a groove cycle and a pattern structure, it can effectively cut through the water film on icy and snowy roads, and can increase the friction between the tire body and the slippery road surface, thereby improving the vehicle's handling stability and driving safety.

[0017] The present invention provides an all-terrain tire suitable for all seasons. By designing a tread block edge structure of different depths, the contact area between the tire body and icy or muddy roads can be increased, forming more bite points. During driving, the tire can more effectively embed into the snow layer or mud, breaking up the ice surface or mud blocks, helping to keep the tire clean and maintain grip. At the same time, this structure can also provide better lateral rigidity and enhance the stability of the tire when turning. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] The following combination Figure 1-Figure 7The present invention describes an all-terrain tire suitable for all seasons, including a tire body 1, the tread of which is provided with shoulder pattern blocks 2, edge pattern blocks 3, and center pattern blocks 4; it should be noted that the tire body 1 is arranged in a circular ring shape, and the shoulder pattern blocks 2, edge pattern blocks 3, and center pattern blocks 4 are all arranged on the outer wall of the tire body 1. The extremely fine secondary grooves 9, groove circulation 10 and pattern structure 16 provided on the shoulder pattern blocks 2, edge pattern blocks 3, and center pattern blocks 4 can improve the grip of the tire body 1 on wet and slippery roads, thereby ensuring the normal driving of the vehicle.

[0023] It should be noted that the shape of the shoulder pattern block 2 is as follows: Figure 2 , and the shoulder pattern block 2 includes a first long pattern block 5 and a first short pattern block 6, the outer walls of the first long pattern block 5 and the first short pattern block 6 are composed of a vertical wall, an upper arc-shaped wall, a lower arc-shaped wall and an oblique side wall. Furthermore, the oblique side wall is arranged relative to the vertical wall, and a first gap groove is formed between the oblique side wall and the edge pattern block 3. The first gap groove is vertically arranged on the outer wall surface of the tire body 1. During the rotation of the tire body 1, the water in the first gap groove is easily separated from the tire body 1 under the action of centrifugal force and gravity. However, the difference between the first long pattern block 5 and the first short pattern block 6 is that the length and width of the first long pattern block 5 are greater than the length and width of the first short pattern block 6; in addition, the first long pattern block 5 and the first short pattern block 6 are alternately arranged on the outer wall surface of the tire body 1 in sequence.

[0024] It should also be noted that: the shoulder pattern blocks 2 are distributed in multiple groups on the outer wall surface of the tire body 1, and a first gap groove is left between adjacent first long pattern blocks 5 and first short pattern blocks 6, which is used to guide water attached to the surface of the tire body 1 to the first gap groove between the oblique side wall and the edge pattern blocks 3; secondly, two groups of shoulder pattern blocks 2 are located on both sides of each group of edge pattern blocks 3 and center pattern blocks 4.

[0025] The shape of the edge pattern block 3 is shown in FIG. Figure 2The edge pattern block 3 includes a second long pattern block 7 and a second short pattern block 8. The outer wall of the second long pattern block 7 is composed of a long tip wall, a long lower arc wall, a long left arc wall and a long right arc wall. The outer wall of the second short pattern block 8 is composed of a short upper arc wall, a short lower arc wall, a short left arc wall and a short right arc wall. Furthermore, a second gap groove is formed between the long lower arc wall and the short upper arc wall, and a third gap groove is provided between the long right arc wall, the short right arc wall and the center pattern block 4. The second gap groove and the third gap groove are both obliquely arranged on the outer wall surface of the tire body 1. During the rotation of the tire body 1, the water in the second gap groove and the third gap groove is easily separated from the tire body 1 under the action of centrifugal force and gravity. The difference between the second long pattern block 7 and the second short pattern block 8 is the long tip wall arranged on the top of the second long pattern block 7; in addition, the second long pattern block 7 and the second short pattern block 8 are both staggered in sequence on the outer wall surface of the tire body 1.

[0026] The side pattern blocks 3 are distributed in multiple groups on the outer wall surface of the tire body 1, and a second gap groove is left between adjacent second long pattern blocks 7 and second short pattern blocks 8, which is used to guide water attached to the surface of the tire body 1 to the second gap groove between the oblique side wall and the side pattern blocks 3; secondly, each group of side pattern blocks 3 and center pattern blocks 4 is located in the middle position of multiple groups of shoulder pattern blocks 2.

[0027] It should be noted that, referring to Figure 2 As shown, the first long pattern block 5 and the first short pattern block 6 are circumferentially distributed on the edge of the outer wall of the tire body 1, and the second long pattern block 7 and the second short pattern block 8 are circumferentially distributed in the middle of the outer wall of the tire body 1, and the first long pattern block 5, the first short pattern block 6, the second long pattern block 7, and the second short pattern block 8 are all raised and arranged on the outside of the tire body 1, and gaps are provided between the first long pattern block 5, the first short pattern block 6, the second long pattern block 7, and the second short pattern block 8. By setting the protrusions and gaps, the roughness of the outer wall of the tire body 1 can be increased, and then the friction between the tire body 1 and the ground can be increased, thereby greatly improving the friction between the tire body 1 and the wet and slippery road surface.

[0028] Furthermore, the first long pattern block 5, the first short pattern block 6, the second long pattern block 7, the second short pattern block 8, and the center pattern block 4 are all provided with very fine auxiliary grooves 9, and the very fine auxiliary grooves 9 are arranged in a V shape. Figure 3As shown, an extremely fine auxiliary groove 9 is provided in each pattern block within the layout of the pattern structure 16, with the tip of the extremely fine auxiliary groove 9 facing the tire body 1 in a counterclockwise direction, and the open end of the extremely fine auxiliary groove 9 facing the tire body 1 in a clockwise direction. When the vehicle is driving fast on a slippery road, the extremely fine auxiliary groove 9 arranged in a V shape on the tire body 1 is quickly pressed on the water surface, which can break a layer of water film on the water surface like a blade. At the same time, the extremely fine auxiliary groove 9 can also quickly discharge the water, and through the cooperation of multiple extremely fine auxiliary grooves 9 arranged in a V shape, the water film on the icy and snowy road surface can be effectively cut, thereby effectively improving the stability of the vehicle during driving control.

[0029] Furthermore, a groove cycle 10 is provided between each two side pattern blocks 3 in the circumferential direction of the central pattern block 4, and the central pattern block 4 and the corresponding two groups of side pattern blocks 3 form a pattern structure 16. Figure 4 As shown, the groove circulation 10 is arranged in an inclined O-shape. During the driving process of the vehicle, the groove circulation 10 arranged on the outside of the tire body 1 can throw mud or snow water out of the groove, thereby improving the drainage efficiency of the groove, thereby greatly improving the grip of the tire body 1 on wet and slippery roads.

[0030] Furthermore, the first long pattern blocks 5 and the first short pattern blocks 6 are alternately arranged in the circumferential direction of the tire body 1, and the second long pattern blocks 7 and the second short pattern blocks 8 are alternately arranged in the circumferential direction of the tire body 1. It should be noted that the multiple first long pattern blocks 5 are equidistantly arranged around the outer wall of the tire body 1, and the multiple second long pattern blocks 7 are equidistantly arranged around the outer wall of the tire body 1. By protruding the multiple first long pattern blocks 5 and the multiple first short pattern blocks 6 on the outer wall of the tire body 1, the roughness of the outer wall of the tire body 1 can be increased, thereby increasing the friction between the outer wall of the tire body 1 and the ground, thereby improving the grip of the tire body 1 on wet and slippery roads.

[0031] Furthermore, each group of shoulder pattern blocks 2 corresponds to a group of side pattern blocks 3, the shoulder pattern blocks 2 and the side pattern blocks 3 are arranged in the transverse direction of the tire body 1, the side pattern blocks 3 are staggered in the circumferential direction of the tire body 1, the center pattern blocks 4 are arranged in the groove cycle 10, and the pattern structure 16 is propeller-shaped. It should be noted that, referring to Figure 3 As shown, the pattern structure 16 includes a group of central pattern blocks 4 and four groups of side pattern blocks 3. In the pattern structure 16, the central pattern block 4 is located at the center of the pattern structure 16, and the group of central pattern blocks 4 and the four groups of side pattern blocks 3 form a propeller shape.

[0032] Furthermore, the central pattern block 4 in the transverse direction of the tire body 1 is arranged at the center of the two sets of side pattern blocks 3, and the central pattern block 4 forms an angle α with the transverse direction of the tire body 1, and the angle α is between 25° and 40°. Figure 4 As shown, the angle α is formed between 27° and 35°. At this time, if the angle α is too large, the edge length of the center block 4 in contact with the road surface during driving will be reduced, affecting the gripping ability of the tire body 1 on wet and muddy roads.

[0033] Furthermore, the number of the very fine auxiliary grooves 9 distributed on the first long pattern block 5, the first short pattern block 6, the second long pattern block 7, the second short pattern block 8, and the center pattern block 4 is 3 to 4, and the connection between the very fine auxiliary grooves 9 forms an angle β, which is formed between 120° and 180°. It should be noted that, referring to Figure 5 As shown, preferably, the angle β is formed between 135° and 150°. If the angle β is too small, the probability of the tread block breaking increases during extreme driving. A reasonable angle setting can extend the life cycle of the tire body 1.

[0034] Furthermore, the edge portions of the first long pattern block 5, the first short pattern block 6, the second long pattern block 7, the second short pattern block 8, and the center pattern block 4 are all provided with pattern block edge structures of different depths. Figure 6 and Figure 7 As shown, the edge structures of the tread blocks of different depths are arranged in a stepped manner, which can increase the contact area between the tire body and the icy or muddy road surface, form more bite points, and can more effectively embed into the snow layer or mud during driving, breaking up the ice or mud, which helps to keep the tire clean and grip. The edge structure of the tread blocks can also provide better lateral rigidity and enhance the stability of the tire when turning.

[0035] Furthermore, the pattern block edge structure includes a first stepped pattern block 11, a second stepped pattern block 12, a third stepped pattern block 13, a fourth stepped pattern block 14, and a fifth stepped pattern block 15. It should be noted that, referring to Figure 7 As shown, the lengths of the first stepped pattern block 11, the second stepped pattern block 12, the third stepped pattern block 13, the fourth stepped pattern block 14 and the fifth stepped pattern block 15 increase in a stepped manner, and can protrude from the outer wall surface of the tire body 1, thereby increasing the friction between the outer wall of the tire body 1 and the wet road surface.

[0036] Furthermore, the thickness of the first stepped pattern block 11, the second stepped pattern block 12, the third stepped pattern block 13, the fourth stepped pattern block 14, and the fifth stepped pattern block 15 is within the range of 0 mm to 4 mm. Figure 6 and Figure 7 As shown in the figure, the edge structure of the tread blocks of different depths can also improve the lateral rigidity of the tire, enhance the stability of the tire when turning, and form a larger contact area between the tire and the icy or muddy road surface. During driving, the tire can be more effectively embedded in the snow or mud, breaking up the ice or mud, which helps to keep the tire clean and maintain grip.

[0037] Working principle of the present invention: By setting the groove circulation 10 and the pattern structure 16, the water film on the icy and snowy road surface can be effectively cut, and the friction between the tire body 1 and the wet and slippery road surface can be improved, thereby improving the vehicle's handling stability and driving safety. By setting the extremely fine secondary grooves 9, the drainage efficiency of the main grooves of the tire body 1 can be improved, thereby improving the grip of the tire body 1 on wet and slippery roads. By designing the edge structure of the pattern blocks with different depths, the contact area between the tire body 1 and the icy and snowy road surface or muddy road surface can be increased to form more bite points, and the snow layer or mud can be more effectively embedded in the driving process to break up the ice surface or mud blocks, which helps to keep the tire body 1 clean and grippy. At the same time, this structure can also provide better lateral rigidity and enhance the stability of the tire body 1 when turning.

[0038] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
