DETAILED DESCRIPTION

[0027] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0028] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0029] Reference Figure 1-7 The utility model provides a tire with a multi-terrain pattern structure, the tire has a tread 1 and shoulders 2 formed on both sides of the tread 1, the tread 1 is divided into a first pattern area, a second pattern area, a third pattern area and a fourth pattern area which are equidistant and arranged in sequence. The first pattern area, the second pattern area, the third pattern area and the fourth pattern area are all vertical strip-shaped partitions divided in the unfolded state of the tire, and the number of the second pattern area, the third pattern area and the first pattern area on the same tire is two.

[0030] The first pattern area, the second pattern area and the third pattern area are symmetrical about the middle line of the fourth pattern area, and are respectively located on both sides of the fourth pattern area in a V-shaped distribution. The first pattern area is formed with a first pattern block 11, the second pattern area is formed with a second pattern block 12, the third pattern area is formed with a third pattern block 13, and the fourth pattern area is formed with a fourth pattern block 14. The first pattern block 11, the second pattern block 12, the third pattern block 13 and the fourth pattern block 14 are linearly arranged on the same extension line and form a V-shaped single-side group. The angle between the extension lines of the two V-shaped single-side groups is 80-100°. One of the above-mentioned pattern areas is vertically provided with a plurality of corresponding patterns distributed in an array. Taking the second pattern area as an example, the second pattern area is provided with a plurality of second pattern blocks 12 distributed in a vertical array.

[0031] In one embodiment, the first pattern block 11, the second pattern block 12, the third pattern block 13 and the fourth pattern block 14 are all distributed transversely on the rolling path of the tire. In each pattern area, the arrangement particles of each section of the longitudinal pattern are arranged from the center to the sides: the fourth pattern block 14, the third pattern block 13, the second pattern block 12, and the first pattern block 11, wherein the number of the third pattern block 13, the second pattern block 12, and the first pattern block 11 is two groups, which are located on both sides of 14 and are symmetrically distributed about the center line. The longitudinal pattern prevents the vehicle from sliding sideways when turning or passing a corner, and has good drainage performance. Among them, each single pattern of the fourth pattern block 14, the third pattern block 13, the second pattern block 12, and the first pattern block 11 is Figure 2 As shown, it is distributed laterally, which can play a good role in heat dissipation and noise elimination. In bad road conditions, it can increase the longitudinal grip and has a good braking force.

[0032] Among them, the second pattern block 12, the third pattern block 13 and the fourth pattern block 14 are distributed on the same straight line. When driving on different ground surfaces, the pattern combination with a V-shaped arrangement angle can provide stable grip, especially when the V-shaped angle is 80-100 degrees. At this time, the pattern blocks with angle distribution can maintain good grip under normal driving and provide a good driving experience for the driver. In addition, it can prevent the vehicle from sliding sideways when turning or cornering, and has good drainage.

[0033] In one embodiment, the edge draft angles of the second pattern block 12, the third pattern block 13 and the fourth pattern block 14 are 10-25°. The transverse cross-sections of the second pattern block 12, the third pattern block 13 and the fourth pattern block 14 all show a gradually decreasing trend of being wider at the bottom and narrower at the top. According to experimental tests, the second pattern block 12, the third pattern block 13 and the fourth pattern within this draft angle range can ensure good grip when in contact with the ground. When the edge draft angle with a large angle contacts the ground, the top end can increase the shear force on hard terrain, making it easier to grip the ground, thereby improving traction and preventing slipping.

[0034] In one embodiment, the draft angle of the edge of the first pattern block 11 is 15-20°. When the edge of the first pattern block 11 grips the ground during cornering, it can stably grip the ground to prevent the vehicle from skidding.

[0035] In one embodiment, the height of the first pattern block 11 is at least twice the height of the fourth pattern block 14. The pattern of the tire is low in the middle and gradually decreases in height toward both sides, which provides good grip when cornering and ensures good passability.

[0036] In one embodiment, at least one connecting groove 3 is formed on each of the first pattern block 11, the second pattern block 12, the third pattern block 13 and the fourth pattern block 14, and the depth of the connecting groove 3 is 1 / 2 of the height of the fourth pattern block 14. The depth of the connecting groove 3 is 1 / 2 of the height of the middle pattern block, that is, the fourth pattern block 14. Under the action of the connecting groove 3, when the first pattern block 11, the second pattern block 12, the third pattern block 13 and the fourth pattern block 14 are in contact with the ground, the deformation amount of the top portion at the top where the connecting groove 3 is provided increases, so that the pattern block can stably grip the ground and improve traction.

[0037] In one embodiment, the adjacent second pattern blocks 12 and third pattern blocks 13, as well as the adjacent third pattern blocks 13 and fourth pattern blocks 14 are connected by connecting ribs 4, and the height of the connecting ribs 4 is 1 / 3-1 / 2 of the height of the first pattern blocks 11. By providing the connecting ribs 4, the material strength between two adjacent pattern blocks is improved, the deformation of the pattern blocks is reduced, and the service life of the tire can be increased. In addition, the connecting ribs 4 can increase the effect of crushing mud and sand, so that the tire can throw out mud and sand when driving to increase the self-cleaning performance.

[0038] In one embodiment, a protective stripe 10 is provided on the shoulder 2, and the cross section of the protective stripe 10 in the thickness direction is semicircular, triangular, or quadrilateral, and the width and height of the protective stripe 10 on the tire base surface are 0.15 mm-0.5 mm. The protective stripe 10 forms a raised pattern to prevent the side of the tire from being scratched or cut when driving in mountainous areas.

[0039] In one embodiment, it also includes a cord layer 5, a wire bead 6, an anti-scratch layer 7, a tread layer 8 and a sidewall layer 9 which are arranged in sequence from the inside to the outside, and the tread and the sidewall are formed on the outer surface of the tread layer 8.

[0040] Although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the utility model. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the utility model.
