[0003] Therefore, a high-performance rain tire for scooter motorcycles is still needed to solve the above problems. Utility Model Content
[0004] This utility model provides a high-performance rain tire for scooter motorcycles that solves the above-mentioned problems.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A high-performance rain tire for scooters includes a tread layer. A pattern group is formed on the outer surface of the tread layer, arranged in groups along the outer periphery of the tire. The pattern group includes a first strip groove, a toothed section, and a second strip groove arranged at intervals. The first strip groove, the toothed section, and the second strip groove are partially parallel on the tread layer. The toothed section includes a strip-shaped section, a toothed section, and sound-absorbing holes. The sound-absorbing holes are formed at both ends of the strip-shaped section. The toothed sections are evenly distributed in an array along at least one side of the strip-shaped section. One end of the first strip groove is close to the equator of the tread layer, and the other end is close to the edge of the tread layer, with at least two rounded corners between the two ends.
[0007] In one embodiment, the second strip groove includes a first branch and a second branch having the same connection point, the first branch and the second branch having a V-shaped distribution and mutually parallel portions.
[0008] In one embodiment, the cross-sectional shape of the sound-absorbing hole is circular or a regular polygon.

[0018] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many 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 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 therefore repeated descriptions of them will be omitted.
[0019] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.
[0020] Reference Figure 1-2This utility model provides a high-performance rain tire for scooters, including a tread layer 1, which is the surface layer of the tire and a rubber layer for contacting the ground. The outer surface of the tread layer 1 has a tread pattern grouped along the outer circumference of the tire. The tread pattern group includes a first groove 11, a toothed section 12, and a second groove 13 arranged sequentially at intervals. In the rolling direction, the first groove 11, the toothed section 12, and the second groove 13 are arranged sequentially. During rolling, the tread pattern group on one side contacts the ground first, and then the tread pattern group on the other side of the equator contacts the ground next.
[0021] On the tread layer 1, the first strip groove 11, the toothed section 12, and the second strip groove 13 are partially parallel, and each of the first strip groove, toothed section 12, and second strip groove 13 has a bending inflection point. The toothed section 12 includes a strip section 121, a toothed section 122, and a sound-absorbing hole 123. The sound-absorbing hole 123 is formed at both ends of the strip section 121. When the tire rolls, the sound waves generated between the toothed sections 122 are absorbed by the sound-absorbing hole when they reach the end point, which reduces some of the tire noise without attenuating the grip of the strip section 121 and the toothed section 122. The toothed sections 122 are linearly and uniformly distributed, which can disperse water flow when the tire rolls onto a wet surface. The toothed sections 122 are evenly arrayed along at least one side of the strip section 121. One end of the first strip groove 11 is close to the equator of the tread layer 1, and the other end is close to the edge of the tread layer 1, and there are at least two rounded corners between the two ends. Rounded corners allow for greater deformation space when the tires are gripping the ground, preventing tires from squeezing against each other and thus providing stable friction and improving tire handling.
[0022] In one embodiment, the second strip groove 13 includes a first branch 131 and a second branch 132 with the same connection point. The first branch 131 and the second branch 132 have V-shaped portions and parallel portions. The second strip groove 13 has an overall layered γ-shape. The first branch 131 and the second branch 132 can be intersecting branch grooves. The first branch 131 can also have an extended end extending near the equator to provide stable friction for the tire. In addition, the branching shape of the first branch 131 and the second branch 132 near the tire edge can provide stable friction for the tire while preventing water from remaining between the tire treads, reducing tire tread wear, and improving tire grip.
[0023] In one embodiment, the cross-sectional shape of the sound-absorbing hole 123 is circular or a regular polygon. Preferably, the sound-absorbing hole 123 is circular, and the circle is a complete circle connected to the strip portion 121. Through the design of the arc-shaped end of the sound-absorbing hole 123, the noise generated by vibration can be absorbed when tire noise occurs, so that the noise is absorbed on the inner side of the arc portion, thereby reducing the tire noise generated when the tire is driving.
[0024] In one embodiment, the cross-section of the toothed portion 122 is triangular. Preferably, the toothed portion 122 is triangular, which can improve the tire's grip on the ground. The continuous toothed portion 122 is corrugated overall, which improves the deformation capability of the tire edge, can grip the ground tightly, and improve driving control.
[0025] In one embodiment, the draft angle of the first groove 11 and the second groove 13 is 40 degrees. This 40-degree angle creates a larger effective contact area when the tire contacts the ground, enhancing lateral friction. This design provides stronger lateral support during high-speed cornering or emergency braking, reducing the risk of vehicle skidding.
[0026] In one embodiment, the depth ratio of the strip portion 121, the toothed portion 122, and the sound-absorbing hole 123 is 1:2:2. Experimental results show that when the depths of the strip portion 121, the toothed portion 122, and the sound-absorbing hole are in this ratio, the strip portion 121, acting as a groove penetrating all the toothed portions 122 and the sound-absorbing hole, transmits tire noise generated by friction between the toothed portions 122 and the sound-absorbing hole 123 through a relatively shallow groove, and also exhibits high friction and flexible grip.
[0027] In one embodiment, the tread layer 1 is further provided with a buffer layer 2, a ply layer 3 and an inner layer 4 arranged sequentially in the thickness direction.
[0028] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
