DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Now, the exemplary embodiments will be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; on the contrary, these embodiments are provided so that the present utility model will be more complete and comprehensive, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their repeated description will be omitted.

[0021] The words expressing positions and directions described in the present utility model are all illustrated with reference to the drawings, but can be changed according to needs, and all the changes made are included in the protection scope of the present utility model.

[0022] Refer to Figure 1-2, the present utility model provides a simple electric vehicle tire, including a tread layer 1. A center groove 11 is provided at the midline of the outer surface of the tread layer 1. On both sides of the center groove 11, a first tread area 12 and a second tread area 13 are alternately arranged along the extending direction of the center groove 11. The center groove 11, as an annular groove on the outer surface of the tire, when rotating and encountering a puddle, the water flow can be effectively squeezed and flow along the extending direction of the center groove 11, ensuring that the bottom of the tire can fully contact the ground and providing stable friction.

[0023] The first tread area 12 includes a first vertical groove 121, a first bent groove 122, and a second vertical groove 123 that are sequentially adjacent to the center groove 11. The first vertical groove 121 of the first tread area 12 is adjacent to the center groove 11 and is parallel to the center groove 11, which can assist the center groove 11 in draining water, increasing the contact area between the tire and the ground, and enhancing the grip.

[0024] The second tread area 13 includes a second bent groove 131 and a wavy area 132 that are sequentially adjacent to the center groove 11.

[0025] The first tread area 12 and the second tread area 13 are surface patches in the shape of an approximate parallelogram.

[0026] The sequentially arranged first tread area 12 and second tread area 13 can effectively enhance the grip of the tire, and the structures of the first tread area 12 and the second tread area 13 are simple, simplifying the structural design and improving the driving controllability.

[0027] In one embodiment, the structures of the first tread areas 12 respectively arranged on both sides of the center groove 11 are symmetrical, and the structures of the second tread areas 13 respectively arranged on both sides of the center groove 11 are symmetrical. The symmetrical structural design can balance the frictions on both sides of the tire, enabling the tire to maintain good balance.

[0028] In one embodiment, the first vertical groove 121 is parallel to the center groove 11, and a part of the first bent groove 122 is parallel to the first vertical groove, and the other part is parallel to the second vertical groove 123. The two parts of the first bent groove 122 are respectively parallel to the first vertical groove 121 and the second vertical groove 123, which can effectively increase the grip of the first vertical groove 121 and the drainage capacity of the second vertical groove 123.

[0029] In one embodiment, the wavy area 132 is located between the adjacent second bent groove 131 and the first bent groove 122. The wavy area 132 is filled with wavy lines, and it has been tested that it can effectively enhance the grip of both sides of the tire on the ground and improve the overall passability of the tire.

[0030] In one embodiment, a reinforcing portion 6 is further provided on a part of the second bent groove 131 parallel to the center line. The reinforcing portion 6 is filled in the second bent groove 131. The reinforcing portion 6 can firmly hold the tread rubber blocks on both sides of the groove, making the contact with the ground more uniform, preventing uneven wear on the tire surface, and having a certain shock absorption and earthquake resistance ability, thereby improving the service life of the tire. The reinforcing portion 6 can be a glue filler.

[0031] In one embodiment, the draft angle of the second vertical groove 123 is degrees and is in an outwardly expanding shape. This can better protect the tire, prevent the tire from cracking when the tire is running, and improve the service life of the tire.

[0032] In one embodiment, a reinforcing layer 2 and an inner layer 3 are sequentially provided inside the tread layer 1. A bead wire 4 is provided at the joint between the inner layer 3 and the reinforcing layer 2 for docking with the wheel hub. A bead portion 5 is formed near the bead wire 4 on the tire side. The bead portion 5 can effectively enhance the bead rigidity and improve the heat dissipation performance.

[0033] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention without departing from the principles and purposes of the present invention. All such changes should fall within the protection scope of the claims of the present invention.
