[0002] Currently, vans are widely used in transportation, warehousing, and distribution industries due to their even load distribution and flexible loading capabilities. With the development of the logistics industry, the driving speed and driving time of vans have also increased. Due to the long-term pressure of heavy loads and high-speed driving, the tires of vans wear out faster, shortening their service life.

[0003] In existing technologies, manufacturers typically use complex tire tread patterns to improve the wear resistance and grip of van tires in order to meet the needs of long-term van operation.

[0004] However, vans generate significant noise and vibration during long-term driving, affecting the driver's riding experience. Existing technology focuses on tire wear resistance in tire tread design, while neglecting the comfort of the tire during driving. Utility Model Content

[0012] Furthermore, there are multiple first connecting grooves and recesses, all of which are spaced apart along the circumference of the tire. An adjacent first connecting groove and a recess form a first dividing group. These multiple first dividing groups divide the tread pattern into multiple tread pattern blocks.

[0036] To address the problem that existing tires used in vans cannot simultaneously meet the requirements of wear resistance and comfort, this application provides a tire tread structure and a tire having the same.

[0037] like Figures 1 to 2 As shown, the tire tread structure includes multiple longitudinal grooves 1, a first connecting groove 4, a reinforcing structure 5, and a first sheet group 6. Each longitudinal groove 1 extends circumferentially along the tire, and the multiple longitudinal grooves 1 are spaced apart along the width direction of the tire to divide the tread into two shoulder tread portions 2 and multiple crown tread portions 3 located between the two shoulder tread portions 2. The first connecting groove 4 is provided on the crown tread portion 3 to connect the longitudinal grooves 1 located on both sides of the crown tread portion 3. The reinforcing structure 5 is provided on the bottom wall of the first connecting groove 4 to connect the two groove walls of the first connecting groove 4. The first sheet group 6 is provided on the crown tread portion 3, and the first sheet group 6 includes at least two first sheet structures 610, which are located on both sides of the first connecting groove 4 along the circumferential direction of the tire. Each of the first sheet structures 610 includes a first sub-sheet structure 611, and each first sub-sheet structure 611 extends into the first connecting groove 4. Along the extension direction of the first connecting groove 4, at least two first sub-sheet structures 611 are located at both ends of the reinforcing structure 5.

[0038] Applying the technical solution of this embodiment, the tire tread structure includes multiple longitudinal grooves 1, each extending circumferentially along the tire. The multiple longitudinal grooves 1 are spaced apart along the width direction of the tire to divide the tread into two shoulder tread portions 2 and multiple crown tread portions 3 located between the two shoulder tread portions 2. A first connecting groove 4 is disposed on the crown tread portion 3 to connect the longitudinal grooves 1 located on both sides of the crown tread portion 3. A reinforcing structure 5 is disposed on the bottom wall of the first connecting groove 4 to connect the two groove walls of the first connecting groove 4. A first sheet-like group 6 is disposed on the crown tread portion 3, and the first sheet-like group 6 includes at least two first sheet-like structures 610, located on both sides of the first connecting groove 4 along the circumferential direction of the tire. Each of the first sheet-like structures 610 includes a first sub-sheet-like structure 611, and each first sub-sheet-like structure 611 extends into the first connecting groove 4. At least two first sub-sheet-like structures 611 are located at both ends of the reinforcing structure 5 along the extending direction of the first connecting groove 4. Thus, during tire operation, the arrangement of multiple longitudinal grooves 1 and the first connecting groove 4 ensures the tire's heat dissipation and drainage performance, achieving good wet-weather handling. Simultaneously, the arrangement of the reinforcing structure 5 connects the two walls of the first connecting groove 4, ensuring the overall stability of the tire, improving the rigidity and strength of the tread pattern 3, thereby enhancing the tire's wear resistance and ensuring its wear resistance during long-term high-speed driving. Furthermore, it reduces tube noise, lowering tire noise during operation, thus solving the problem in existing technologies where tires used in vans cannot simultaneously meet the requirements of wear resistance and comfort. Meanwhile, the arrangement of the first piece group 6 enhances the rigidity of the tread blocks, further improving the tire's wear resistance; on the other hand, it optimizes the distribution of the tire's contact surface with the ground, dispersing the friction and impact forces of the ground on the tire, ensuring the tire's integrity and stress stability, as well as its grip and wear resistance.

[0039] In this embodiment, three longitudinal grooves 1 are provided.

[0040] It should be noted that the number of longitudinal grooves 1 is not limited to this and can be adjusted according to actual working conditions and usage requirements. Optionally, the number of longitudinal grooves 1 can be two, four, five, or more.

[0041] In this embodiment, two first sheet-like structures 610 are provided.

[0042] In this embodiment, the first sheet structure 610 is a steel sheet, wherein the thickness of the steel sheet is 0.8 mm.

[0043] In this embodiment, the tire tread is designed with central symmetry along the center plane S. This arrangement ensures that the tread pattern shape and distribution on both sides of the tire are consistent, guaranteeing uniform wear during driving, extending tire lifespan, and ensuring tire balance during driving.

[0044] like Figure 1 and Figure 2 As shown, each first sheet structure 610 also includes a second sub-sheet structure 612. One end of the second sub-sheet structure 612 is connected to the first sub-sheet structure 611, and the other end of the second sub-sheet structure 612 extends into a longitudinal groove 1 located on one side of the tread pattern 3. In two longitudinal grooves 1 adjacent to the tread pattern 3, at least two second sub-sheet structures 612 extend into the two longitudinal grooves 1 respectively. The first sub-sheet structure 611 and the second sub-sheet structure 612 are arranged at an angle, and each second sub-sheet structure 612 is arranged at a first angle A1 with the circumference of the tire, satisfying: 67°≤A1≤71°. This angled arrangement of the second sub-sheet structure 612 and the first sub-sheet structure 611 causes the first sheet structure 610 to be bent, enhancing the visual appeal of the tire and improving its aesthetics. Meanwhile, the above-mentioned configuration can balance the stress of the tread blocks, ensuring the stability and durability of the tread portion 3 in multiple directions, ensuring the grip of the tread portion 3, and improving the stability and wear resistance of the tread portion 3.

[0045] In this embodiment, the first included angle A1 satisfies: A1 = 69°, so as to ensure that the value of the first included angle A1 is more appropriate.

[0046] like Figure 1 and Figure 2As shown, the tire tread structure also includes a recess group 7, a second plate group 8, and a third plate group 9. The recess group 7 is disposed on the tread pattern portion 3, with one end extending to one side of the tread pattern portion 3, and the other end of the recess group 7 having a predetermined distance from the other side of the tread pattern portion 3. The recess group 7 includes a first recess 710 and a second recess 720, which extend to different sides of the tread pattern portion 3, respectively. The second plate group 8 is disposed on the tread pattern portion 3 and includes at least two second plate structures 810. These at least two second plate structures 810 are located at the ends of the first recess 710 and the second recess 720 closest to each other, and each second plate structure 810 is set at a second included angle A2 with respect to the circumference of the tire. The second included angle A2 satisfies: 8° ≤ A2 ≤ 12°. The third piece group 9 is disposed on the tread pattern portion 3. The third piece group 9 includes at least two third piece structures 910. Along the circumference of the tire, the at least two third piece structures 910 are respectively located on both sides of the recess group 7. The at least two third piece structures 910 are disposed in a one-to-one correspondence with at least two second piece structures 810. One end of the third piece structure 910 is connected to the second piece structure 810, and the other end of the third piece structure 910 extends into the longitudinal groove 1 located on one side of the tread pattern portion 3. Among them, in the two longitudinal grooves 1 adjacent to the tread pattern portion 3, at least two third piece structures 910 extend into the two longitudinal grooves 1 respectively. Each third piece structure 910 is disposed at a third included angle A3 with the circumference of the tire, and the third included angle A3 satisfies: 67°≤A3≤71°. In this way, the arrangement of the recess group 7 ensures both the water drainage performance of the tread pattern 3 and the rigidity of the tread blocks, thereby improving the wear resistance of the tread pattern 3 and achieving a balance between water drainage and wear resistance. Simultaneously, the angle of the second plate structure 810 further enhances the grip and driving stability of the tread pattern 3. Furthermore, the angle of the third plate structure 910 reduces noise during tire rolling, ensuring smoothness during tire operation. The combined arrangement of the second plate structure 810 and the third plate structure 910 provides lateral support to the tread pattern 3, further ensuring the stability and durability of the tire in multiple directions. Meanwhile, the arrangement of the second plate group 8 and the third plate group 9 can be combined with the first plate group 6 and the first lateral groove, which on the one hand improves the stability of the tread pattern 3, enhances the structural strength of the tread pattern 3, and improves the rigidity and wear resistance of the tread pattern 3; on the other hand, it can improve the tire's guidance and stability during rolling.

[0047] In this embodiment, there are two of each of the second sheet structure 810 and the third sheet structure 910.

[0048] In this embodiment, the second included angle A2 satisfies: A2 = 10°, so as to ensure that the value of the second included angle A2 is more appropriate.

[0049] In this embodiment, the third included angle A3 satisfies: A3 = 69°, so as to ensure that the value of the third included angle A3 is more appropriate.

[0050] like Figure 1 As shown, the tire tread structure also includes longitudinal fine grooves 130, which extend circumferentially along the tire. These grooves are disposed on the shoulder tread portion 2 to divide it into an outer shoulder tread portion 210 and an inner shoulder tread portion 220. Multiple longitudinal grooves 1 include a first longitudinal groove 110 and a second longitudinal groove 120. The first longitudinal groove 110 is located between two adjacent crown tread portions 3. The second longitudinal groove 120 is adjacent to the shoulder tread portion 2. The contact portion between the tire and the driving surface has a width T. The widths W1 of the first longitudinal groove 110, W2 of the second longitudinal groove 120, W3 of the longitudinal fine groove 130, and T satisfy the following conditions: 0.04T ≤ W1 ≤ 0.08T, 0.05T ≤ W2 ≤ 0.09T, and 0.008T ≤ W3 ≤ 0.012T. Width W1 satisfies: 10.5mm ≤ W1 ≤ 12mm, width W2 satisfies: 13mm ≤ W2 ≤ 14.5mm, and width W3 satisfies: 1mm ≤ W3 ≤ 3mm. This configuration improves the tire's water drainage performance, ensuring grip on wet surfaces, preventing slippage, and enhancing wet handling. It also improves the tire's aesthetics. Furthermore, this configuration optimizes the tread block layout, reducing rolling resistance and improving fuel economy and comfort.

[0051] In this embodiment, the land-sea ratio of the tire tread ranges from 20% to 35%.

[0052] Specifically, the land-to-sea ratio of the tire tread is 26%. This configuration ensures that the tread blocks have sufficient area to more effectively disperse impact forces from the ground, reducing tire wear and improving tire durability. Furthermore, it reduces vibration during tire-ground contact, enhancing driving comfort.

[0053] In this embodiment, the width W1 and the width T satisfy the following conditions: W1 = 0.06T, and width W1 = 11.5mm.

[0054] In this embodiment, the width W2 and the width T satisfy the following conditions: W2 = 0.07T, and width W2 = 13.5mm.

[0055] In this embodiment, the width W3 and the width T satisfy the following conditions: W1 = 0.01T, and width W3 = 2mm.

[0056] In this embodiment, the depth of the longitudinal fine groove 130 is 1 mm.

[0057] like Figure 1 and Figure 2 As shown, the tire tread structure also includes a third recess 10, a fourth sheet structure 11, and a fifth sheet structure 12. The third recess 10 is disposed on the outer shoulder tread portion 210, with one end extending to the tire shoulder and the other end having a predetermined distance from the side of the outer shoulder tread portion 210 near the longitudinal groove 130. The third recess 10 is positioned at a fourth angle A4 with the tire's circumference, satisfying: 71°≤A4≤75°. The fourth sheet structure 11 is disposed on the outer shoulder tread portion 210, with one end extending into the longitudinal groove 130 located on one side of the outer shoulder tread portion 210, and the other end extending into the side of the tire. The fifth piece structure 12 is disposed on the outer shoulder tread portion 210. Along the circumference of the tire, one end of the fifth piece structure 12 extends into the third recess 10 near the longitudinal fine groove 130, and the other end of the fifth piece structure 12 is at a predetermined distance from the fourth piece structure 11. In this way, the arrangement of the third recess 10 ensures the water drainage performance of the outer shoulder tread portion 210, ensures the wet handling performance of the outer shoulder tread portion 210, and ensures the grip of the outer shoulder tread portion 210, further improving the tire's water drainage performance and grip. Meanwhile, the arrangement of the fourth piece structure 11 and the fifth piece structure 12 ensures the rigidity of the outer shoulder tread portion 210, further improving the tire's wear resistance; on the other hand, it optimizes the distribution of the contact surface between the outer shoulder tread portion 210 and the ground, dispersing the friction and impact forces of the ground on the outer shoulder tread portion 210, further ensuring the tire's integrity and stress stability, and guaranteeing the tire's grip and wear resistance.

[0058] like Figure 1 and Figure 2As shown, the tire tread structure also includes a second connecting groove 13 and a sixth piece structure 14. The second connecting groove 13 is disposed on the inner shoulder tread portion 220, with one end extending into the second longitudinal groove 120 and the other end extending into the longitudinal fine groove 130. The sixth piece structure 14 is disposed on the inner shoulder tread portion 220, with one end extending into the second longitudinal groove 120 and the other end extending into the longitudinal fine groove 130. This arrangement of the second connecting groove 13 ensures the water drainage performance of the inner shoulder tread portion 220, guarantees its wet handling, and ensures its grip, further improving the tire's water drainage performance and grip. Meanwhile, the arrangement of the sixth piece structure 14 ensures the rigidity of the inner shoulder tread 220, optimizes the distribution of the contact surface between the inner shoulder tread 220 and the ground, disperses the friction and impact force of the ground on the inner shoulder tread 220, and further improves the wear resistance and stability of the tire.

[0059] like Figure 1 As shown, there are multiple first connecting grooves 4 and multiple recess groups 7. These multiple first connecting grooves 4 and multiple recess groups 7 are spaced apart along the circumference of the tire. An adjacent first connecting groove 4 and a recess group 7 form a first dividing group. These multiple first dividing groups divide the tread pattern 3 into multiple tread pattern blocks 310. At least one tread pattern block 310 is provided with at least one first sheet structure 610, at least one third sheet structure 910, and at least a portion of the second sheet group 8. There are multiple fourth sheet structures 11. These multiple fourth sheet structures 11 are spaced apart along the circumference of the tire to divide the outer shoulder tread pattern 210 into multiple outer shoulder tread blocks 211. There are multiple second connecting grooves 13 and multiple sixth plate-shaped structures 14, all spaced apart along the circumference of the tire. An adjacent second connecting groove 13 and a sixth plate-shaped structure 14 form a second dividing group, which divides the inner shoulder tread portion 220 into multiple inner shoulder tread blocks 221. Multiple outer shoulder tread blocks 211 are arranged in a one-to-one correspondence with multiple inner shoulder tread blocks 221, and multiple outer shoulder tread blocks 211 are arranged in a one-to-one correspondence with multiple crown tread blocks 310. The outer shoulder tread blocks 211 and their corresponding inner shoulder tread blocks 221 and crown tread blocks 310 form sub-tread groups 15. This arrangement results in multiple sub-tread groups 15 along the tire's circumference, reducing noise generated by tire-road friction and noise generated by internal air vibration, making the tire quieter during driving and improving driving comfort.

[0060] like Figure 2As shown, the second connecting groove 13 and its corresponding first connecting groove 4 are staggered. Along the tire's circumference, the distance H1 between the second connecting groove 13 and its corresponding first connecting groove 4 satisfies the following condition with respect to the length L of the sub-pattern group 15: 0.27L≤H1≤0.42L, where H1 satisfies: 11.9mmL≤H1≤12.3mm. Similarly, the first connecting grooves 4 on adjacent tread portions 3 are staggered. Along the tire's circumference, the distance H2 between two corresponding first connecting grooves 4 satisfies the following condition with respect to the length L of the sub-pattern group 15: 0.5L≤H2≤0.7L, where H2 satisfies: 19.9mmL≤H2≤20.3mm. This arrangement, on the one hand, disrupts the arrangement of tire tread patterns, reducing tire noise and improving tire stability and grip during driving; on the other hand, it also improves tire handling in complex driving conditions such as cornering. At the same time, the combination of offset design and symmetrical design can optimize the appearance of the tire and improve the visual coordination and balance of the tire.

[0061] In this embodiment, H1 satisfies: H1 = 12.1 mm, to ensure that the value of H1 is more appropriate.

[0062] In this embodiment, H2 satisfies: H2 = 20.1 mm, to ensure that the value of H2 is more appropriate.

[0063] like Figure 1 As shown, the tire tread structure also includes multiple tread pattern groups, each of which includes at least two adjacent sub-tread pattern groups 15. The multiple tread pattern groups include a first tread pattern group 16, a second tread pattern group 17, and a third tread pattern group 18. The lengths L1 of the first tread pattern group 16, L2 of the second tread pattern group 17, and L3 of the third tread pattern group 18 satisfy the following relationship: L1 < L2 < L3. This arrangement ensures that the tread patterns on the tire tread structure are distributed in groups, resulting in a certain pitch ratio between the tread pattern groups. This allows the tire to generate a more stable vibration frequency during rolling, reducing the vibration transmitted from the tire to the vehicle body, reducing tire resonance, lowering tire noise, and improving tire driving comfort and stability. Meanwhile, each tread pattern group includes a cyclic arrangement of two adjacent sub-tread patterns 15. On the one hand, this further reduces tire resonance and tire noise, while also ensuring tire handling performance, enhancing the rigidity of the tire tread blocks, improving tire wear resistance, and ensuring tire driving stability and safety under various road conditions. On the other hand, it makes the tire more visually appealing and enhances its aesthetics.

[0064] In this embodiment, the first pattern group 16 includes a first sub-pattern group 151 and a second sub-pattern group 152. Along the circumference of the tire, the number of the first sub-pattern group 151 and the second sub-pattern group 152 are both 14.

[0065] In this embodiment, the second pattern group 17 includes a third sub-pattern group 153 and a fourth sub-pattern group 154. Along the circumference of the tire, the third sub-pattern group 153 has 9 sets, and the fourth sub-pattern group 154 ​​has 13 sets.

[0066] In this embodiment, the third pattern group 18 includes a fifth sub-pattern group 155 and a sixth sub-pattern group 156. Along the circumference of the tire, the fifth sub-pattern group 155 has 11 sets, and the sixth sub-pattern group 156 has 7 sets.

[0067] This application also provides a tire, which includes the above-described tire tread structure.

[0068] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0069] The tire tread structure includes multiple longitudinal grooves, each extending circumferentially along the tire. These grooves are spaced apart along the tire's width to divide the tread into two shoulder tread portions and multiple crown tread portions located between them. A first connecting groove is provided on the crown tread portion to connect the longitudinal grooves located on both sides of the crown tread portion. A reinforcing structure is provided on the bottom wall of the first connecting groove to connect its two walls. A first sheet-like group is provided on the crown tread portion, comprising at least two first sheet-like structures, located on either side of the first connecting groove along the tire's circumferential direction. Each first sheet-like structure includes a first sub-sheet structure extending into the first connecting groove, with at least two first sub-sheet structures located at both ends of the reinforcing structure along the extension direction of the first connecting groove. In this way, the arrangement of multiple longitudinal grooves and the first connecting groove during tire operation ensures the tire's heat dissipation and drainage performance, achieving excellent wet-weather handling. Simultaneously, the reinforced structure connects the two walls of the first connecting groove, ensuring overall tire stability, improving the rigidity and strength of the tread pattern, and thus enhancing wear resistance, guaranteeing the tire's durability during prolonged high-speed driving. Furthermore, it reduces tube noise, lowering tire noise during operation, thereby solving the problem of existing tires used in vans failing to simultaneously meet wear resistance and comfort requirements. Additionally, the arrangement of the first plate group enhances the rigidity of the tread blocks, further improving tire wear resistance; it also optimizes the distribution of the tire-ground contact surface, dispersing the friction and impact forces from the ground, ensuring the tire's integrity and stress stability, and guaranteeing both grip and wear resistance.
