[0039] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] refer to Figure 1 and Figure 2An embodiment of the present application provides an all-terrain tire, which includes: a tire body 1, a plurality of annular steel wires 6 and a plurality of connecting steel wires 7.

[0041] Among them, a plurality of annular steel wires 6 are embedded in the tire body 1, and the plurality of annular steel wires 6 are arranged at intervals along the axial direction X of the tire body 1, and each annular steel wire 6 extends along the circumferential direction R of the tire body 1. The circumferential direction R surrounds the axial direction X. Exemplarily, a plurality of connecting steel wires 7 are arranged at intervals along the circumferential direction R of the tire body 1, each connecting steel wire 7 extends along the axial direction X, and the plurality of annular steel wires 6 are connected by a plurality of connecting steel wires 7.

[0042] That is to say, the plurality of connecting steel wires 7 and the plurality of annular steel wires 6 together form an annular mesh structure. Specifically, two adjacent connecting steel wires 7 and two adjacent annular steel wires 6 together form a mesh 61, and the plurality of meshes 61 form the annular mesh structure.

[0043] The all-terrain tire provided in the embodiment of the present application has a plurality of annular steel wires 6 and a plurality of connecting steel wires 7 embedded in the tire body 1, and the plurality of annular steel wires 6 and the plurality of connecting steel wires 7 form an annular mesh structure, and the mesh structure can effectively improve the structural strength of the tire body 1. When a sharp object pierces the tire body 1, the mesh structure can block the sharp object and prevent the sharp object from further piercing the tire body 1, which can effectively prevent the sharp object from piercing the tire body 1, thereby preventing the all-terrain tire from being pierced by the sharp object, reducing the risk of tire replacement, and improving the durability of the all-terrain tire.

[0044] Exemplarily, multiple annular steel wires 6 are located at the center of the tire body 1 along the axial direction X, so that the above-mentioned mesh structure covers the center of the tire body 1 along the axial direction X, thereby improving the structural strength of the center of the tire body 1, preventing the center of the tire body 1 from being punctured by sharp objects, reducing the risk of tire replacement, and improving the durability of all-road tires.

[0045] The embodiment of the present application does not specifically limit the specific number of the annular steel wires 6. For example, in the embodiment of the present application, the number of the annular steel wires 6 is eleven. In other possible implementations, the number of the annular steel wires 6 can also be ten, twelve, thirteen, or more.

[0046] The embodiment of the present application does not impose any specific limitation on the specific number of connecting steel wires 7, as long as multiple annular steel wires 6 can be connected to form the above-mentioned annular mesh structure.

[0047] The embodiment of the present application does not impose any specific limitation on the connection method between the connecting steel wire 7 and the annular steel wire 6 . For example, in some possible implementations, each connecting steel wire 7 is welded to a plurality of annular steel wires 6 .

[0048] In some possible implementations, continue to refer to Figure 1 The outer surface of the tire body 1 is provided with a plurality of center grooves 2. The plurality of center grooves 2 are arranged at intervals along the circumferential direction R. Exemplarily, the plurality of center grooves 2 are not connected to each other, so that the air stays in the center groove 2 for a short time, so that the air can be discharged quickly, thereby reducing the tire noise generated by the all-terrain tire during driving and improving the user experience.

[0049] The specific number of the central grooves 2 is not specifically limited in the embodiment of the present application. For example, in some possible implementations, the number of the central grooves 2 may be six, seven, eight, or more.

[0050] Exemplarily, each center groove 2 is located in the middle of the tire body 1 along the axial direction X. And each center groove 2 extends along the circumferential direction R.

Moreover, each side groove 3 is connected to the adjacent center groove 2 along the axial direction X, and along the circumferential direction R, two adjacent side grooves 3 are not connected, so as to reduce the time that the air stays in the center groove 2 and the side groove 3, so that the air can be discharged quickly, thereby reducing the tire noise generated by the all-terrain tire during driving and improving the user experience.

[0053] Specifically, along the axial direction X, a connecting groove 4 is provided between each central groove 2 and one side groove 3 , and each central groove 2 is connected to one side groove 3 via the connecting groove 4 .

[0054] Exemplarily, there are three connecting grooves 4 between each central groove 2 and a side groove 3, and the three connecting grooves 4 are spaced apart along the circumferential direction R, and a first anti-slip block 8 is defined between each two adjacent connecting grooves 4 in the three connecting grooves 4 along the circumferential direction R. In other words, each first anti-slip block 8 is provided with a connecting groove 4 on both sides along the circumferential direction R, and each anti-slip block 8 is located between a central groove 2 and a side groove 3 along the axial direction X. The first anti-slip block 8 can increase the grip of the all-terrain tire and improve the anti-skid effect of the all-terrain tire to adapt to a variety of complex road conditions.

[0055] The embodiment of the present application does not impose any specific limitation on the number of connecting grooves 4 between each central groove 2 and a side groove 3. For example, in other possible embodiments, the number of connecting grooves 4 between each central groove 2 and a side groove 3 can also be two, four, five or more.

[0056] In some possible implementations, continue to refer to Figure 1In the axial direction X, a plurality of drainage grooves 5 are provided at both side edges of the outer surface of the tire body 1, and the plurality of drainage grooves 5 at each side edge are arranged at intervals along the circumferential direction R. Each drainage groove 5 is connected to a side groove 3, so that the air in the center groove 2 and the side groove 3 can be discharged from the all-terrain tire through the drainage groove 5.

[0057] Exemplarily, the bottom of each drainage groove 5 is an inclined surface, and along the axial direction X, from the center of the tire body 1 to the edge of the tire body 1, the bottom of the drainage groove 5 is inclined toward the tire body 1 along the radial direction Y of the tire body 1. After such arrangement, when it rains, the speed at which rainwater flows out of the drainage groove 5 can be increased, and rainwater can be prevented from staying on the surface of the tire body 1, thereby improving the anti-skid effect of the all-terrain tire on rainy days.

[0058] For example, continue to refer to Figure 1 The extension direction of each drainage groove 5 is set at an acute angle to the axial direction X, so that the drainage effect of the all-terrain tire can be further improved. In addition, two adjacent drainage grooves 5 along the axial direction X (i.e., the drainage grooves 5 on both sides of the tire body 1 along the axial direction X) are in an "eight" shape.

[0059] In some possible implementations, a second anti-sliding block 9 is defined between two adjacent drainage grooves 5 along the circumferential direction R. In other words, each second anti-sliding block 9 is provided with a drainage groove 5 on both sides along the circumferential direction R. The second anti-sliding block 9 can further increase the grip of the all-terrain tire and improve the anti-skid effect of the all-terrain tire to adapt to a variety of complex road conditions.
