Technical Field

[0001] The present application relates to the technical field of pneumatic tires, and in particular to a tread pattern structure of a pneumatic tire for an all-terrain vehicle for rock climbing and a pneumatic tire for an all-terrain vehicle for rock climbing. Background Art

[0002] Although the ATV tires widely used in the market have met the needs of users to a certain extent, they still face many challenges in certain environments. For example, under extreme road conditions such as rocks, traditional tires often lack grip due to unreasonable pattern design, which can easily cause slippage or even failure to escape, seriously affecting driving safety and passability. In addition, traditional tires generate a lot of noise when driving at high speeds, which reduces the driving experience. With the increasing popularity of outdoor adventure activities and technological advances, the demand for ATV tires that can maintain high performance under various harsh conditions is also increasing. Summary of the invention

[0003] In order to enhance the user's driving experience when driving a vehicle on rugged outdoor roads, the present application provides an inflatable tire and a tread pattern structure for an all-terrain vehicle for rock climbing.

[0004] In a first aspect, the present application provides a tread pattern structure of a pneumatic tire for an all-terrain vehicle for rock climbing, which adopts the following technical solution: A tread pattern structure of an inflatable tire for an all-terrain vehicle for rock climbing, comprising a plurality of pattern block groups equidistantly arranged around the circumference of the tire, wherein the pattern block group comprises a plurality of pattern block single groups spaced apart around the circumference of the tire, wherein the pattern block single group comprises a crown portion, a shoulder portion and a sidewall portion, wherein the shoulder portion is respectively arranged at both ends of the crown portion, and the sidewall portion is arranged on a side of the shoulder portion away from the crown portion.

[0005] By adopting the above technical solution, the reasonable layout of the crown, shoulder and sidewalls of the tire makes the tire have better grip and stability when driving on complex terrain such as rocks. At the same time, the multi-pitch design between the single group of crown pattern blocks effectively disperses the contact pressure between the tire and the ground, reduces the single-point load, reduces driving noise, and improves driving comfort.

[0006] Optionally, the sidewall portion includes a plurality of flat-convex portions spaced laterally apart, a ridge-convex portion is provided on the side of the flat-convex portion away from the shoulder portion, the ridge-convex portion includes two ridge slopes, a friction ridge is provided at the junction of the ridge slopes, and the height of the plane where the friction ridge is located is the same as the height of the flat-convex portion.

[0007] By adopting the above technical solution, the flat-convex and ridge-convex design of the sidewall significantly improves the tire's grip and puncture resistance on complex terrains such as rocks. Specifically: the combined design of the flat-convex and ridge-convex increases the actual contact area between the tire and the rock surface, improves friction, and thus enhances grip, especially on inclined or uneven ground. A friction ridge is provided at the junction of the two slopes of the ridge-convex part, and the height of the plane where the friction ridge is located is the same as that of the flat-convex part. This design not only increases the rigidity of the tire side, but also can generate stronger fitting force in the rock gap, further improving grip. This multi-plane design can also effectively disperse external impact force, reduce the risk of the tire being penetrated by sharp objects, improve the tire's puncture resistance, and extend the tire's service life.

[0008] Optionally, the crown portion includes a Z-shaped convex portion, the Z-shaped convex portion having a connecting portion and two mutually parallel first extension portions and second extension portions, the first extension portion and the second extension portion are connected via the connecting portion, the extension portion is arranged at an angle to the transverse direction, and the first extension portion and the second extension portion are both perpendicular to the connecting portion.

[0009] By adopting the above technical solution, the Z-shaped convex design of the crown can effectively disperse the contact pressure of the tire on complex terrain such as rocks, reduce the single-point load, and thus improve the tire's grip and stability. At the same time, the unique structural design of the connection and extension of the Z-shaped convex part enables the tire to better adapt to uneven roads during driving, improving passability and handling.

[0010] Optionally, the crown portion also includes a first oblique groove, a second oblique groove and a third oblique groove, the first oblique groove is arranged at a position where the first extension portion is connected to the connecting portion, the second oblique groove is arranged at a position where the second extension portion is connected to the connecting portion, and the third oblique groove is arranged at a central position of the connecting portion, dividing the connecting portion into two centrally symmetrical fish scale islands.

[0011] By adopting the above technical solution, the first, second and third oblique grooves not only effectively disperse the pressure generated by the tire during driving, but also increase the tire's anti-skid performance, and improve the tire's grip and stability on complex terrain such as rocks. The third oblique groove divides the connection part into two centrally symmetrical fish scale islands, further enhancing the tire's handling and anti-skid performance when driving at high speeds, and improving the driving experience.

[0012] Optionally, a V-shaped groove is provided on the fish scale island, an L-shaped groove is provided on the first extension portion, and an I-shaped groove is provided on the second extension portion.

[0013] By adopting the above technical solution, V-grooves are set on the fish scale islands, which can effectively disperse the pressure generated by the tire when driving on complex terrain, increase the friction between the tire and the ground, and thus improve the grip and stability. The design of the V-groove helps the tire to grip the ground better, especially on slippery or uneven roads, which can improve the traction and handling of the tire. The L-groove is set on the first extension part, which helps to further disperse the pressure of the tire in contact with the ground, reduce the single-point load, thereby improving the grip and stability of the tire, and at the same time increase the lateral rigidity of the tire, and improve the handling and anti-skid performance of the tire on complex terrain such as rocks. The I-groove is set on the second extension part, which helps to disperse the pressure generated by the tire during driving and increase the anti-skid performance of the tire; the design of the I-groove can improve the grip and stability of the tire on complex terrain, especially when driving at high speeds, which can improve the handling and anti-skid performance of the tire, thereby improving the driving experience.

[0014] Optionally, the shoulder portion includes a step connection block, the step connection block includes a step low surface and a step high surface, the step low surface is used to connect to any one of the first extension portion and the second extension portion, and the step high surface is used to connect to the flat convex portion.

[0015] By adopting the above technical solution, the design of the step connection block on the shoulder can significantly improve the fit and grip performance of the tire when climbing rocks. Specifically, the step low surface is connected to the first extension part or the second extension part of the crown part, which ensures the smooth transition of the tire on the rock surface, reduces the slippage caused by poor contact between the tire and the ground during driving, and improves driving stability. Especially when there are many rock gaps, the step low surface can better embed into the rock gaps and provide stronger fit. The step high surface is connected to the flat convex part of the sidewall, which increases the actual contact area between the sidewall and the rock surface, and cooperates with the step low surface embedded in the rock gap to produce a stronger fit and provide additional friction support.

[0016] Optionally, the height difference between the step lower surface and the step higher surface is 5mm-8mm.

[0017] By adopting the above technical solution, this height difference design not only helps the tire to fit into the rock gap, but also can effectively disperse the pressure on the tire, reduce tire damage caused by excessive local force, and extend the service life of the tire.

[0018] In a second aspect, the present application provides an inflatable tire for an all-terrain vehicle for rock climbing, which adopts the following technical solution: A pneumatic tire for an all-terrain vehicle for rock climbing comprises a tire body and an internal skeleton layer arranged inside the tire body. The surface of the tire body is provided with the tread pattern structure of the pneumatic tire for an all-terrain vehicle for rock climbing.

[0019] By adopting the above technical solution and utilizing the above-mentioned tread pattern structure of the all-terrain vehicle pneumatic tire for rock climbing, the applicability and safety of the all-terrain vehicle pneumatic tire in complex terrain conditions such as rocks are improved, and the risk of safety accidents caused by tire failure is reduced.

[0020] Optionally, the tire body is made of high-strength natural rubber material, and the internal skeleton layer is made of aramid fiber material.

[0021] By adopting the above technical solution, the main body of the tire is made of high-strength natural rubber material, which can ensure that the tire has good flexibility and wear resistance in complex terrain, while providing excellent grip and tear resistance. The internal skeleton layer uses aramid fiber material, which further improves the impact strength and durability of the tire, reduces the probability of damage to the tire under extreme road conditions, extends the service life of the tire, and ensures the stability and safety of the vehicle in complex terrain such as rock climbing.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the unique multi-pitch tread block group design, the pressure distribution is effectively dispersed, the single-point load is reduced, the noise generated by the tire during driving is significantly reduced, and the driving experience is improved; 2. The shoulder adopts a step design, which makes it easier for the lower step surface of the shoulder to be inserted into the rock gap, generating a stronger fit, and cooperates with the higher step surface to provide additional friction support, significantly improving the tire's grip and stability on the rock surface; 3. The sidewall adopts a multi-plane design, which increases the actual contact area with the rock surface, enhances grip while reducing the risk of external foreign matter penetration, and improves the tire's puncture resistance.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] The embodiment of the present application discloses a tread pattern structure of a pneumatic tire for an all-terrain vehicle for rock climbing.

[0028] like Figure 1 and Figure 2 As shown in the figure, the tread pattern structure of the pneumatic tire for rock climbing all-terrain vehicles includes a group of pattern blocks arranged equidistantly around the circumference of the tire, and the group of pattern blocks includes a group of pattern blocks arranged at intervals around the circumference of the tire, and the single pattern block group includes a crown part, a shoulder part and a side part, and the shoulder part is respectively arranged at both ends of the crown part, and the side part is arranged on the side of the shoulder part away from the crown part. When driving on complex terrain such as rocky surfaces, the optimized layout of the crown, shoulder and side parts of the tire significantly enhances the tire's grip and stability.

[0029] In this embodiment, the tread block group includes three single tread block groups, the spacing between the single tread block groups is a first pitch 11 and a second pitch 12, and the spacing between the multiple tread block groups is a third pitch 13. The relationship between the three is that the third pitch 13 is greater than the second pitch 12, which is greater than the first pitch 11, and the difference between the pitches is not greater than 1.5 mm. The multi-pitch design strategy of the crown tread block group effectively disperses the contact stress between the tire and the ground, reduces the local load, and prevents the tire from resonating during rolling, thereby reducing the noise level during driving and improving driving comfort.

[0030] like Figure 1 and Figure 2 As shown, specifically, the tire side portion includes a plurality of laterally spaced flat-convex portions 1, a ridge-convex portion 2 is provided on the side of the flat-convex portion 1 away from the shoulder portion, the ridge-convex portion 2 includes two ridge slopes, a friction ridge 3 is provided at the junction of the ridges and slopes, and the height of the plane where the friction ridge 3 is located is the same as the height of the flat-convex portion 1.

[0031] The design of the plano-convex portion 1 and the ridged portion 2 on the sidewall significantly improves the traction and puncture resistance of the tire on complex terrains, such as rock surfaces. Specifically, the coordinated design of the plano-convex portion 1 and the ridged portion 2 increases the contact area between the tire and the rock surface, thereby increasing the friction coefficient and enhancing the traction performance, especially on inclined or uneven ground. The friction ridge 3 is configured at the junction of the double slopes of the ridged portion 2, and the height of the plane where it is located is consistent with that of the plano-convex portion 1. This design not only enhances the rigidity of the tire sidewall, but also can generate a stronger embedding force in the gap between rocks, further enhancing traction. In addition, the multi-plane design can effectively disperse external impact forces, reduce the risk of the tire being punctured by sharp objects, thereby improving the puncture resistance of the tire and extending the service life of the tire.

[0032] like Figure 1 and Figure 2 As shown, the crown portion includes a Z-shaped convex portion, which has a connecting portion and two mutually parallel first extension portions 4 and second extension portions 5. The first extension portion 4 and the second extension portion 5 are connected by the connecting portion, and the extension portion is set at an angle of 20°-30° with the horizontal direction. In this embodiment, the first extension portion 4 and the second extension portion 5 are both set at an angle of 28° with the horizontal direction, and the first extension portion 4 and the second extension portion 5 are both perpendicular to the connecting portion. The Z-shaped convex portion design of the crown portion can effectively disperse the contact pressure of the tire on complex terrain such as rocks, reduce single-point load, and thus improve the grip and stability of the tire. At the same time, the structural design of the connecting portion and the extension portion of the Z-shaped convex portion enables the tire to better adapt to uneven roads during driving, thereby improving passability and handling.

[0033] In addition, if Figure 1 and Figure 2 As shown, the crown portion also includes a first oblique groove 7, a second oblique groove 8 and a third oblique groove 9. The first oblique groove 7 is arranged at the position where the first extension portion 4 is connected to the connection portion, the second oblique groove 8 is arranged at the position where the second extension portion 5 is connected to the connection portion, and the third oblique groove 9 is arranged at the central position of the connection portion, dividing the connection portion into two centrally symmetrical fish scale islands 6. The configuration of the first oblique groove 7, the second oblique groove 8 and the third oblique groove 9 significantly disperses the stress generated by the tire during driving, and improves the tire's anti-skid performance, and enhances the tire's adhesion and stability on complex terrains such as rocks. The third oblique groove 9 further enhances the tire's handling performance and anti-skid ability at high speeds by dividing the connection portion into two centrally symmetrical fish scale islands 6, thereby improving the driving and riding experience.

[0034] Optionally, a V-groove 601 is designed in the fish scale island 6 structure to effectively disperse the pressure generated by the tire during driving on complex terrain, and to enhance the friction coefficient between the tire and the ground, thereby improving the tire's grip and stability. The two sides of the V-groove 601 are perpendicular to each other, and one side is parallel to the first extension 4. The V-groove 601 structure is conducive to better ground grip of the tire, especially on slippery or uneven roads, which can improve the tire's traction and handling performance. The L-groove 401 is introduced in the first extension 4 to further disperse the pressure when the tire contacts the ground. One side of the L-groove 401 is parallel to the first extension 4 and is connected to the first oblique groove 7, and the other side is parallel to the circumferential arrangement of the tire tread, thereby reducing the single-side load, enhancing the tire's grip and stability, and being able to improve the tire's lateral rigidity, and enhancing the tire's handling performance and anti-skid ability on complex terrains such as rocks. An I-shaped groove 501 is provided on the second extension portion 5, and the I-shaped groove 501 is parallel to the second extension portion 5 and is connected to the second oblique groove 8, and its purpose is to disperse the pressure generated by the tire during driving and improve the tire's anti-skid performance; the design of the I-shaped groove 501 can enhance the tire's grip and stability on complex terrain, especially under high-speed driving conditions, and can improve the tire's handling performance and anti-skid ability, thereby optimizing the driving and riding experience. In addition, the cutting force of the boundaries of the V-shaped groove 601, the L-shaped groove 401 and the I-shaped groove 501 on the gravel road surface is also multi-directional and diverse, so that the gravel road surface is more easily broken into fine particles, which is more conducive to the tire's sand and rock removal, and improves the tire's passability and traction on gravel ground.

[0035] like Figure 1 and Figure 2 As shown, the shoulder portion includes a step connection block 10, and the step connection block 10 includes a step low surface 1001 and a step high surface 1002. The step low surface 1001 is used to connect with any one of the first extension portion 4 and the second extension portion 5, and the step high surface 1002 is used to connect with the flat convex portion 1. The step connection block 10 design of the shoulder portion enhances the fit and grip performance of the tire when climbing rocks. Specifically, the step low surface 1001 is connected to the first extension portion 4 or the second extension portion 5 of the crown portion, ensuring a smooth transition of the tire on the rock surface, reducing the slippage caused by poor contact between the tire and the ground during driving, and improving driving stability. Especially in the case of a large number of rock gaps, the step low surface 1001 can be more effectively embedded in the rock gaps, providing a stronger fit. The high step surface 1002 is connected to the flat convex part 1 of the tire side, which increases the actual contact area between the tire side and the rock surface, and cooperates with the low step surface 1001 embedded in the rock gap to generate a stronger fitting force and provide additional friction support.

[0036] The height difference between the step low surface 1001 and the step high surface 1002 is 5mm-8mm. This height difference design not only helps the tire fit into the rock gap, but also effectively disperses the pressure on the tire, reduces tire damage caused by excessive local force, and extends the service life of the tire.

[0037] The embodiment of the present application also discloses a pneumatic tire for an all-terrain vehicle for rock climbing.

[0038] like Figure 2 As shown, the pneumatic tire for rock climbing all-terrain vehicle comprises a tire body 14 and an internal skeleton layer arranged inside the tire body 14, and the surface of the tire body 14 is provided with the above-mentioned pneumatic tire tread pattern structure for rock climbing all-terrain vehicle. The above-mentioned pneumatic tire tread pattern structure for rock climbing all-terrain vehicle improves the applicability and safety of the pneumatic tire for rock climbing all-terrain vehicle in complex terrain conditions such as rocks, and reduces the risk of safety accidents caused by tire failure.

[0039] In terms of material selection, the tire body 14 is made of high-strength natural rubber material, and the internal skeleton layer is made of aramid fiber material. The tire body 14 is made of high-strength natural rubber material, which can ensure that the tire has good flexibility and wear resistance in complex terrain, while providing excellent grip and tear resistance. The internal skeleton layer is made of aramid fiber material, which further improves the impact strength and durability of the tire, reduces the probability of damage to the tire under extreme road conditions, extends the service life of the tire, and ensures the stability and safety of the vehicle in complex terrain such as rock climbing.
