Technical Field
[0001] This utility model relates to the field of tire technology, and in particular to an all-terrain tire. Background Technology
[0002] With the increasing maturity and segmentation of the off-road vehicle market in recent years, the emerging off-road vehicle enthusiasts in cities have increasingly diversified demands for driving experience. They are no longer satisfied with conventional urban road driving, but prefer to challenge various complex and ever-changing road conditions, such as muddy roads, sandy roads, gravel roads, and other unpaved surfaces. This trend requires off-road vehicles to not only make breakthroughs in power performance and off-road capability, but also to achieve a balance in ride comfort, cargo carrying capacity, and passenger carrying capacity, in order to meet consumers' expectations for all-around off-road vehicles.
[0003] Tires, as the sole medium of contact between an off-road vehicle and the ground, directly affect the vehicle's safety, handling stability, and overall performance. Especially when facing the aforementioned complex and demanding road conditions, tires must withstand immense deformation pressure, heavy loads, forces in various directions, and the effects of extreme high and low temperatures.
[0004] However, while the standard tire tread designs widely available on the market meet the needs of daily driving to some extent, they fall short in terms of passability, wear resistance, and overall adaptability when facing the complex road conditions unique to off-road vehicles. Standard tread patterns struggle to provide sufficient grip and mud-shedding ability, causing vehicles to easily slip, get stuck, or experience accelerated tire wear on unpaved surfaces such as mud and gravel, severely impacting the driving safety and enjoyment of off-road vehicles.
[0005] Given the above background, there is an urgent need for a new type of tire specifically designed for SUVs and off-road vehicles, which can significantly improve passability, durability and safety in various complex road conditions, thereby better meeting the pursuit of the ultimate off-road experience by emerging urban off-road vehicle owners.

This enhances the all-terrain tire's passability, durability, and safety under various complex road conditions.
[0007] To achieve the above objectives, this utility model provides the following solution:
[0008] This utility model provides an all-terrain tire with a tread pattern structure on the tire tread. The tread pattern structure is centrally symmetrically distributed and includes a tread block body, a chamfer, and a tread groove. The tread block body is connected to the tire tread.

[0012] In one embodiment, when the shoulder tread block is provided with a strip groove, one end of the strip groove is connected to the side of the shoulder tread block away from the tire crown, and the other end of the strip groove extends toward the tire crown; when the outer tread block is provided with a strip groove, one end of the strip groove is connected to the side of the outer tread block close to the tire crown, and the other end of the strip groove extends toward the tire side.
[0013] In one embodiment, the outer tread block is further provided with an arrow groove, the arrow groove being provided on the side of the outer tread block near the tire sidewall, and the tip of the arrow groove pointing towards the side of the outer tread block near the tire sidewall.
[0014] In one embodiment, the central patterned block includes a first patterned block and a second patterned block that are connected to each other.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] The purpose of this invention is to provide an all-terrain tire that solves the problems existing in the prior art. By using the beveled corners of the tread block body, the all-terrain tire has excellent self-cleaning performance against mud, sand and stones on complex road surfaces. By using the transition arc of the tread groove, the problem of groove bottom cracking is reduced, and the tear resistance, impact resistance and puncture resistance of the tread block body are improved. In this way, the all-terrain tire can improve its passability, durability and safety under various complex road conditions.
[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] like Figures 1-4 As shown, this utility model provides an all-terrain tire, a type of tire designed for multi-road driving needs, balancing on-road driving and light off-road performance. Similar to ordinary tires, the all-terrain tire's tread can be divided into a crown, sidewall, and shoulder. A tread pattern structure is provided on the tire tread; the tread pattern structure is large and closely arranged, providing stronger grip and self-cleaning ability. Multiple tread pattern structures are centrally symmetrically distributed, which ensures even force distribution during rolling, more balanced wear, reduced localized wear, and extended service life. Specifically, the tread pattern structure includes a tread block body, a chamfered corner 11, and tread grooves. The tread block body is connected to the tire tread, forming a structure protruding from the tire tread. A chamfered corner 11 is provided at the edge of the tread block body, circumferentially positioned along the edge. The inclination angle of the chamfered corner 11 can be set to 8°–20° to ensure excellent self-cleaning performance against mud, sand, and stones on complex off-road surfaces. The surface of the patterned block body has shallow grooves, the depth of which is less than the height of the patterned block body. The bottom of the grooves is set as a transition arc, which can be a full arc (radius 3mm to 8mm) transition design. This can reduce the problem of groove bottom cracking and improve the tear resistance, impact resistance and puncture resistance of the patterned block body.
[0030] This invention features a centrally symmetrical tread pattern structure on the tire tread. The tread pattern structure includes beveled corners 11 and tread grooves on the main body of the tread blocks. The beveled corners 11 on the main body of the tread blocks ensure that the all-terrain tire has excellent self-cleaning performance against mud, sand, and stones on complex road surfaces. The transition arc of the tread grooves reduces the problem of groove bottom cracking and improves the tear resistance, impact resistance, and puncture resistance of the main body of the tread blocks. This enhances the all-terrain tire's passability, durability, and safety under various complex road conditions.
[0031] In one embodiment, the tread pattern structure is divided into a central tread block 1 and side tread blocks 2. The central tread blocks 1 can be of the same size or different sizes, and the side tread blocks 2 can also be of the same size or different sizes. The different tread patterns distributed on the tire tread surface can form a camouflage-like pattern. The central tread blocks 1 extend circumferentially along the tire crown, meaning their length direction is approximately circumferential. The side tread blocks 2 extend from the tire shoulder towards the tire sidewall and from the tire shoulder to the tire sidewall, meaning their length direction is approximately along the tire width direction. The combination of the central tread block 1 and the side tread block 2 can effectively increase the arrangement area of the tread blocks on the tire tread, forming a relatively wide tread contact surface. The wider tread contact surface can increase the driving range under harsh road conditions. At the same time, the setting of the side tread block 2 can form a special tread curvature at the tire shoulder, thereby optimizing the shape of the contact patch and the distribution of contact stress at the tire shoulder, preventing premature wear at the tire shoulder, and enhancing the contact surface of the all-terrain tire, thereby improving handling stability.
[0032] In one embodiment, combined with Figure 3 As shown, the side tread blocks 2 include interconnected shoulder tread blocks 40 and outer tread blocks 30. The length direction of the shoulder tread blocks 40 is roughly the same as that of the outer tread blocks 30, forming a peanut-like shape. The shoulder tread blocks 40 are mainly located on the tire shoulder, while the outer tread blocks 30 include both the portion located on the tire shoulder and the portion located on the tire sidewall. This arrangement enhances the overall integrity of the tread structure, strengthens the tire wall, effectively improves the wear resistance of the tire sidewall, powerfully digs out mud, sand, and silt, prevents impact from sharp rocks, and improves damage resistance.
[0033] In one embodiment, the shoulder tread block 40 is provided with a strip groove 6, or the outer tread block 30 is provided with a strip groove 6, or both the shoulder tread block 40 and the outer tread block 30 are provided with strip grooves 6. When the shoulder tread block 40 is provided with a strip groove 6, the extending direction of the strip groove 6 is consistent with the extending direction of the shoulder tread block 40; when the outer tread block 30 is provided with a strip groove 6, the extending direction of the strip groove 6 is consistent with the extending direction of the outer tread block 30. Regardless of which of the above arrangements is adopted, the strip grooves 6 are mainly distributed in the tire shoulder position. By setting the strip grooves 6, the lateral and straight-line grip of the all-terrain tire can be improved, the braking performance can be improved, and the high-speed performance and handling performance of the all-terrain tire can be guaranteed.
[0034] In one embodiment, when the shoulder tread block 40 is provided with strip grooves 6, one end of the strip groove 6 is connected to the side of the shoulder tread block 40 away from the tire crown, and the other end of the strip groove 6 extends towards the tire crown; when the outer tread block 30 is provided with strip grooves 6, one end of the strip groove 6 is connected to the side of the outer tread block 30 near the tire crown, and the other end of the strip groove 6 extends towards the tire sidewall. The shoulder tread block 40 and the outer tread block 30 partially overlap in the tire width direction, thereby the strip grooves 6 provided on the shoulder tread block 40 and the strip grooves 6 provided on the outer tread block 30 are circumferentially spaced and neatly distributed at the tire shoulder position. The neatly distributed strip grooves 6 can further improve the grip of the all-terrain tire at the tire sidewall position.
[0035] In one embodiment, the outer tread block 30 is further provided with an arrow groove 7. The arrow groove 7 is located in the tread groove on the surface of the outer tread block 30, on the side of the outer tread block 30 closest to the tire sidewall, and the tip of the arrow groove 7 points towards the side of the outer tread block 30 closest to the tire sidewall. The arrow groove 7 not only enhances the overall aesthetics of the tread block but also reduces abnormal early wear on the shoulder to some extent. In addition, the tire shoulder is the thickest part of the tire in terms of rubber material, and the internal cord ends are concentrated, making it prone to heat accumulation. The arrow groove 7 can further increase the surface area of the tire shoulder, promote airflow, accelerate heat dissipation, and prevent overheating that could damage the all-terrain tire.
[0036] In one embodiment, combined with Figure 2 and Figure 3As shown, the central tread block 1 includes a first tread block 10 and a second tread block 20 connected to each other. The tread grooves of the first tread block 10 and the second tread block 20 are connected by a set of arc-shaped grooves 5, which are spaced out in a fish-scale pattern. The shoulder tread block 40 and the outer tread block 30 are connected by another set of arc-shaped grooves 5, which are also spaced out in a fish-scale pattern. The fish-scale pattern of the arc-shaped grooves 5 allows rainwater to flow better along the tire drainage grooves, improving the lateral drainage capability of the all-terrain tire, quickly breaking the water film between the tire and the ground, enhancing wet grip, making driving more stable in the rain, and significantly shortening the braking distance. In addition, the arc-shaped grooves 5 can also guide the airflow to a certain extent, effectively cooling the high-temperature area of the tire shoulder, extending tire life, and improving driving safety.
[0037] In one embodiment, the edges of the tread blocks are smooth arcs, which improves the flow of the channels between the tread blocks and ensures the self-cleaning performance of sand and mud. Additionally, the rounded design of the tread blocks protects the all-terrain tire from damage by rocks, preventing them from falling off easily. The large tread blocks also increase the vehicle's passability, allowing it to easily handle off-road conditions such as muddy roads, rocky roads, and sand dunes. The central tread block 1 and the side tread blocks 2 differ in shape, size, and arrangement, forming a camouflage pattern. The central tread block 1 and the side tread blocks 2 adopt a concave-convex composite structure design, which can meet the all-terrain tire's climbing performance in off-road conditions and ensure the tire's grip when traversing soft terrain. Furthermore, the side tread blocks 2 improve the all-terrain tire's drainage performance, provide lateral grip, and enhance braking performance. At the same time, the shape of the side tread blocks 2 reduces the land-to-sea ratio and increases tread block rigidity, thereby improving the vehicle's stability when driving straight and turning.
[0038] In one embodiment, combined with Figure 4 As shown, adjacent central tread blocks 1 are connected in the width direction by connecting blocks 4. Connecting blocks 4 protrude a certain height from the tread surface, but their highest point is lower than the height of the tread block body. When using an all-terrain tire, the main friction comes from the contact between the tread block body and the ground. Connecting blocks 4 enhance the structural strength and stability of the central tread blocks 1, reducing the risk of cracking at the bottom of the tread block body and improving the tear resistance between the tread block bodies. In addition to connecting the central tread blocks 1, the sides of connecting blocks 4 feature a rounded design with a radius of 3mm to 8mm.
[0039] In one embodiment, the tread grooves on the surface of the tread block body are provided with wavy grooves 12. The wavy grooves 12 are located near the edge of the tread grooves, and one or more wavy grooves can be provided. The wavy grooves 12 can improve the drainage function of the all-terrain tire in the forward direction of the tire, and can also discharge soft mud and sand, thereby achieving the self-cleaning ability to prevent stones from getting stuck. This not only increases the tire's passability, but also effectively ensures the driving experience on wet and slippery roads and guarantees wet grip.
[0040] In one embodiment, the tire tread is further provided with mud-removal lines 3, which are arranged in a circumferential ring on the tire sidewall. The mud-removal lines 3 can be arranged continuously or intermittently on the same ring. The mud-removal lines 3 are not only aesthetically pleasing but also facilitate continuous mud removal, improving the mud-shaking performance of the all-terrain tire when driving on muddy terrain.
[0041] Overall, the all-terrain tire provided by this utility model has an attractive appearance and can adapt to the passage of complex road surfaces. While taking into account load-bearing performance, traction performance and cushioning performance, it also provides high wear resistance and flexural resistance during driving. This makes the tire not only have stable off-road passing performance, but also ensure tire water drainage performance, achieving optimization and balance of tire performance, and can adapt to driving on complex road conditions in all weather.
[0042] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
