The tire pattern structure of fuel vehicle tires is usually not optimized separately to improve the vehicle's mileage, and consumes a lot of energy, which in turn leads to a reduction in the mileage of pure electric light trucks.

[0025] In order to solve the problem in the prior art that the tire tread structure of electric vehicle tires may lead to a reduction in the mileage of the electric vehicle, the present application provides a tire tread structure and a tire having the same.

[0026] like Figures 1 to 3 As shown, the tire tread structure includes a plurality of longitudinal grooves 10, each of which extends along the circumference of the tire, and the plurality of longitudinal grooves 10 are arranged at intervals along the width direction of the tire to separate the tread into two shoulder pattern portions 20 and a crown pattern portion 30 located between the two shoulder pattern portions 20, and the width W1 of the crown pattern portion 30 and the width W2 of the shoulder pattern portion 20 satisfy: 0.95W1≤W2≤0.99W1. Among them, the contact portion between the tire and the driving surface has a width T, and the depth H of the longitudinal groove 10 and the width T satisfy: 0.065T≤H≤0.069T.

[0027] By applying the technical solution of this embodiment, the plurality of longitudinal grooves 10 of the tire tread structure all extend along the circumference of the tire, and the plurality of longitudinal grooves 10 are arranged at intervals along the width direction of the tire to separate the tread into two shoulder pattern portions 20 and a crown pattern portion 30 located between the two shoulder pattern portions 20, and the width W1 of the crown pattern portion 30 and the width W2 of the shoulder pattern portion 20 satisfy: 0.95W1≤W2≤0.99W1. Among them, the contact portion between the tire and the driving surface has a width T, and the depth H of the longitudinal groove 10 and the width T satisfy: 0.065T≤H≤0.069T. In this way, the setting of the width ratio of the shoulder pattern portion 20 and the crown pattern portion 30 can improve the overall rigidity of the crown pattern portion 30 located in the central area of ​​the tire tread, and the above-mentioned setting of the depth H can improve the rigidity of the shoulder pattern portion 20 and the crown pattern portion 30 during the rolling process of the tire, which not only comprehensively reduces the rolling resistance of the tire, but also minimizes the energy loss caused by deformation of the shoulder pattern portion 20 and the crown pattern portion 30 during the rolling process of the tire, thereby improving the fuel-saving performance of the tire, and further solving the problem in the prior art that the tire tread structure of the electric vehicle tire will lead to a reduction in the mileage of the electric vehicle.

[0028] In this embodiment, the width W1 of the crown pattern portion 30 and the width W2 of the shoulder pattern portion 20 satisfy: W2=0.97W1, so that the width values ​​of the two are more appropriate, further improving the rigidity of the two during the tire rolling process and reducing the rolling resistance of the tire.

[0029] Optionally, the plurality of longitudinal grooves 10 include a first longitudinal groove 11 and a second longitudinal groove 12, and the first longitudinal groove 11 is located between two adjacent crown pattern portions 30. The second longitudinal groove 12 is adjacent to the shoulder pattern portion 20. Among them, the width W3 of the first longitudinal groove 11 and the width W4 of the second longitudinal groove 12 satisfy: 0.92W3≤W4≤0.96W3. In this way, the width value of the longitudinal groove 10 set above can be further adjusted according to the different setting positions thereof, so as to further improve the rigidity of the shoulder pattern portion 20 and the crown pattern portion 30 during the rolling process of the tire, reduce the energy loss caused by the rolling deformation of the tire, and improve the mileage of the electric vehicle using the tire. At the same time, the above setting makes the ratio selection between the width W3 and the width W4 more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0030] In this embodiment, the width W3 of the first longitudinal groove 11 and the width W4 of the second longitudinal groove 12 satisfy: W4=0.94W3, so as to further make the width ratio between the two more appropriate, and further reduce the rolling resistance of the tire.

[0031] like Figure 1As shown, the tire tread structure further includes a sheet structure 40, which is disposed in the crown pattern portion 30, and the two ends of the sheet structure 40 extend into two longitudinal grooves 10 adjacent to the crown pattern portion 30. In this way, the sheet structure 40 improves the rigidity of the crown pattern portion 30 to reduce the rolling resistance of the tire, while allowing the liquid in the longitudinal groove 10 to flow along the sheet structure 40, so as to facilitate the discharge of the liquid in the center of the tire to both sides of the tire, thereby improving the anti-skid performance of the tire.

[0032] Optionally, the sheet structure 40 includes a first sub-sheet structure 41 and a second sub-sheet structure 42 connected to each other, and in two longitudinal grooves 10 adjacent to the crown pattern portion 30, one end of the first sub-sheet structure 41 away from the second sub-sheet structure 42 extends into one longitudinal groove 10, and one end of the second sub-sheet structure 42 away from the first sub-sheet structure 41 extends into the other longitudinal groove 10. The first sub-sheet structure 41 is arranged at a first angle A1 with respect to the width direction of the tire, and the first angle A1 satisfies: 15°≤A1≤20°, and the second sub-sheet structure 42 is arranged at a second angle A2 with respect to the width direction of the tire, and the second angle A2 satisfies: 38°≤A2≤40°. In this way, along the direction from the center plane of the tire to the shoulder of the tire, the angle between the first sub-sheet structure 41 and the second sub-sheet structure 42 and the tire width direction gradually increases to adapt to the actual state of the tire tread structure during the tire rolling process. On the one hand, the sheet structure 40 can absorb the vibration waves generated when the tire rolls to reduce the rolling noise of the tire and improve the user's driving comfort; on the other hand, it can avoid the eccentric wear of the crown pattern portion 30 and improve the tire's anti-eccentric wear performance.

[0033] like Figure 3 As shown, the overall height of the sheet structure 40 adopts a variable height design, that is, a plurality of protrusions are provided on the lower surface of the main structure of the sheet structure 40, so that the corresponding knife grooves are variable depth knife grooves, thereby improving the ability of the sheet structure 40 to absorb vibration waves, further reducing the driving noise of the tire, and improving the user experience.

[0034] Specifically, along the direction from the center plane of the tire to the shoulder of the tire, since the angle between the first sub-sheet structure 41 and the second sub-sheet structure 42 and the tire width direction gradually increases, the liquid close to the center plane of the tire can also flow more easily along the first sub-sheet structure 41 and the second sub-sheet structure 42 to the shoulder side, further improving the tire's anti-skid performance.

[0035] Optionally, the first longitudinal groove 11 is arranged in a straight line; and / or, the second longitudinal groove 12 includes a first sub-longitudinal groove 121 and a second sub-longitudinal groove 122 that are interconnected, and the distance H between the two ends of the second sub-longitudinal groove 122 satisfies: 2mm≤H≤3mm; along the circumference of the tire, the length L1 of the first sub-longitudinal groove 121 and the length L2 of the second sub-longitudinal groove 122 satisfy: 0.4L1≤L2≤0.6L2. In this way, the first longitudinal groove 11 arranged in a straight line can improve the straight-line running ability of the tire, and the above-mentioned arrangement of the second longitudinal groove 12 makes it have a variable tortuous design to ensure that the tire has sufficient grip.

[0036] In this embodiment, the length L1 of the first sub-longitudinal groove 121 and the length L2 of the second sub-longitudinal groove 122 satisfy: L2=0.58L2, so that the ratio between the two is more reasonable, further improving the grip of the tire.

[0037] Optionally, a groove group 13 is formed between the first sub-longitudinal groove 121 and the second sub-longitudinal groove 122 that are interconnected. There are multiple groove groups 13, including a first groove group 13, a second groove group 13 and a third groove group 13. Along the circumferential direction of the tire, the length L3 of the first groove group 13, the length L4 of the second groove group 13 and the length L5 of the third groove group 13 satisfy: 0.77L5≤L3≤0.78L5, 0.52L5≤L4≤0.53L5. In this way, the above configuration enables at least three groups of groove groups 13 of different lengths to be arranged in the second longitudinal groove 12, so that the overall structure of the second longitudinal groove 12 is more chaotic, thereby increasing the refraction and collision frequency of noise in the second longitudinal groove 12, and further reducing the running noise of the tire.

[0038] In this embodiment, the length L3 of the first trench group 13 , the length L4 of the second trench group 13 , and the length L5 of the third trench group 13 satisfy: L3=0.775L5, L4=0.525L5.

[0039] In this embodiment, each groove group 13 also includes a crown pattern portion 30 arranged corresponding to the first sub-longitudinal grooves 121 and the second sub-longitudinal grooves 122 interconnected in the groove group 13, and the corresponding parts on the two shoulder pattern portions 20 and the two crown pattern portions 30 (i.e., the parts corresponding to the groove group 13) actually constitute the pitch of the tire.

[0040] In this embodiment, the groove groups 13 of three different lengths are arranged in an irregular distribution to further reduce the running noise of the tire.

[0041] Optionally, the tire tread structure further includes a recess 50, which is arranged on the crown pattern portion 30, and in the two longitudinal grooves 10 adjacent to the crown pattern portion 30, one end of the recess 50 extends to one longitudinal groove 10, and the other end of the recess 50 is at a preset distance from the other longitudinal groove 10; and / or, the recess 50 is arranged on the shoulder pattern portion 20, and one end of the recess 50 extends to the longitudinal groove 10 adjacent to the shoulder pattern portion 20, and the other end of the recess 50 is at a preset distance from the shoulder of the tire. In this way, the edge of the recess 50 can cut the water film between the tire and the driving surface during the rolling process of the tire, so as to avoid the formation of a complete water film between the two, which leads to a decrease in the anti-skid performance of the tire, thereby improving the handling performance of the tire. At the same time, the above-mentioned setting makes the setting position of the recess 50 more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0042] In this embodiment, the recess 50 provided on the shoulder pattern portion 20 is a first recess 51, and there are a plurality of first recesses 51, and the plurality of first recesses 51 are arranged at intervals along the circumference of the tire. The recess 50 provided on the crown pattern portion 30 is a second recess 52, and there are a plurality of second recesses 52, and the plurality of second recesses 52 are arranged at intervals along the circumference of the tire. Among them, the plurality of first recesses 51 and the plurality of second recesses 52 are arranged in a one-to-one correspondence. In this way, the above arrangement further improves the ability of the tire to cut through the water film, thereby improving the handling performance of the tire and reducing the probability of the tire slipping.

[0043] In this embodiment, the first recess 51 and the corresponding second recess 52 are symmetrically arranged.

[0044] In this embodiment, the first recess 51 and the corresponding second recess 52 are symmetrically arranged with respect to the center plane of the longitudinal groove 10 therebetween, so as to further enhance the ability of the tire to cut through the water film and make the tire tread structure more beautiful.

[0045] Optionally, the bottom of the longitudinal groove 10 is an arc-shaped surface, and the two groove walls of the longitudinal groove 10 are arranged at a third angle A3, and the third angle A3 satisfies: 32°≤A3≤35°; and / or, the shoulder pattern portion 20 is a circumferentially continuous pattern block. In this way, the above-mentioned setting improves the stone removal ability of the tire tread structure on the one hand, and can reduce the possibility of stones being mixed in the tire; on the other hand, the shoulder pattern portion 20 actually adopts a closed shoulder design (circumferentially continuous pattern block) to improve the uniformity of the material force of the shoulder, thereby improving the tire's anti-eccentric wear ability and extending the service life of the tire.

[0046] In this embodiment, the tire tread structure is further provided with a first decorative groove 60 and a second decorative groove 70, the first decorative groove 60 is provided on the crown pattern portion 30 and extends into an annular groove along the circumference of the tire, and the second decorative groove 70 is provided at the end of the sheet structure 40. The second decorative groove 70 is provided at both ends of the sheet structure 40, and along the circumference of the tire, the two second decorative grooves 70 are respectively located on both sides of the sheet structure 40.

[0047] The present application also provides a tire, which includes the tire tread structure described above.

[0048] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0049] The multiple longitudinal grooves of the tire tread structure all extend along the circumference of the tire, and the multiple longitudinal grooves are arranged at intervals along the width direction of the tire to separate the tread into two shoulder pattern parts and a crown pattern part located between the two shoulder pattern parts, and the width W1 of the crown pattern part and the width W2 of the shoulder pattern part satisfy: 0.95W1≤W2≤0.99W1. Among them, the contact part between the tire and the driving surface has a width T, and the depth H of the longitudinal grooves and the width T satisfy: 0.065T≤H≤0.069T. In this way, the setting of the width ratio of the shoulder pattern portion and the crown pattern portion can improve the overall rigidity of the crown pattern portion located in the central area of ​​the tire tread, and the above-mentioned setting of the depth H can improve the rigidity of the shoulder pattern portion and the crown pattern portion during the rolling process of the tire, which not only comprehensively reduces the rolling resistance of the tire, but also minimizes the energy loss caused by deformation of the shoulder pattern portion and the crown pattern portion during the rolling process of the tire, thereby improving the fuel-saving performance of the tire, and further solving the problem in the prior art that the tire tread structure of electric vehicle tires will lead to a reduction in the mileage of electric vehicles.
