Description

Technical Field

[0001] This utility model relates to the field of tire technology, and in particular to an electric vehicle tire with airflow guidance and anti-skid properties. Background Technology

[0002] The development of electric vehicles has placed specific demands on tires. Compared to traditional gasoline-powered vehicles, electric vehicles are characterized by a significantly increased overall weight (mainly due to the battery pack) and the extremely quiet operation of the electric motor. These two core characteristics directly influence the application of tires. The increased weight requires tires to have greater load-bearing capacity to ensure safe support. At the same time, the low-noise characteristics of the electric motor make the tire rolling noise, which was previously masked in gasoline-powered vehicles, more prominent, becoming a key factor affecting ride comfort.

[0003] Tire tread patterns on the market often fail to deliver comprehensive and outstanding performance in terms of wet grip and water drainage. Some tread patterns result in poor water drainage in wet environments, leading to a decrease in grip.

[0004] Therefore, there is still a need for an electric vehicle tire with anti-skid and flow-guiding properties to solve the above problems. Utility Model Content

[0005] This invention provides an electric vehicle tire with airflow guidance and anti-slip properties that solves the above-mentioned problems.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] An electric vehicle tire with anti-skid and flow-guiding features includes a tread layer. The outer surface of the tread layer is used for contacting the ground and gripping the surface. The centerline of the outer surface of the tread layer is the equator. Alternating flow-guiding patterns are arranged on both sides of the equator. Each flow-guiding pattern includes interconnected converging patterns and at least two branching patterns. At least a portion of the edges of the converging patterns tend to be close to or away from the equator; and at least a portion of the width of the converging patterns increases or decreases along the equator.

[0008] At least two diversion lines converge at one end of the converging line. Each diversion line has at least partially parallel portions and intersecting transition portions, the parallel portions being connected to the converging line through the transition portions.

[0009] In one embodiment, a guide portion is connected between the converging groove and the transition portion, the guide portion and the parallel portion are parallel to each other on the tread layer, and the groove width of the guide portion and the parallel portion are the same.

[0010] In one embodiment, the tread layer is further provided with sound-absorbing patterns spaced apart from the guide lines, the sound-absorbing patterns including at least one circular hole and stripes communicating with the circular hole.

[0011] In one embodiment, the sound-absorbing pattern includes a stripe and a circular hole connected to one end of the stripe.

[0012] In one embodiment, the sound-absorbing pattern includes two stripes that form an obtuse angle, and the junction of the inflection point and both ends are circular holes.

[0013] In one embodiment, in the thickness direction, a reinforcing layer and an inner layer are sequentially provided at the bottom of the tread layer, the inner layer is fitted outward at the connection point with the wheel hub, and the inner layer is covered with a steel wire ring.

[0014] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0015] By incorporating alternating flow-guiding patterns on the outer surface, with at least one pattern located near the equator, the system can converge and collect water flow along the equator as the wheel rotates, ultimately directing the converged water or liquid along the flow-guiding patterns to the outer edge of the tire. The flow-guiding patterns on the tire exhibit a tree-like, branching pattern, with the portion near the equator smoothly diverting and guiding the water flow to the outer edge of the tire. This enhances the tire's drainage capacity upon contact with the ground, thereby increasing grip. Furthermore, the gradually decreasing or increasing structure prevents the tire from slipping due to insufficient grip when encountering sudden, unusual road surfaces. Attached Figure Description

[0019] 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.

[0020] 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.

[0021] Reference Figure 1-2 This invention provides an electric vehicle tire with anti-skid and flow-guiding features, comprising a tread layer 1. The outer surface of the tread layer 1 is used for ground contact and gripping. The centerline of the outer surface of the tread layer 1 is the equator. Alternating flow-guiding patterns 2 are arranged on both sides of the equator. Each flow-guiding pattern 2 includes interconnected converging patterns 21 and at least two branching patterns 22. At least a portion of the edges of the converging patterns 21 tend to be close to or away from the equator; and at least a portion of the width of the converging patterns 21 increases or decreases along the equator. The tread layer 1 serves as the tire structure in contact with the ground, with the equator located in the center of the tire. The flow-guiding patterns 2 are alternately distributed on both sides of the equator, with adjacent flow-guiding patterns 2 evenly spaced and symmetrically staggered along the equator. When in contact with the ground, this arrangement balances the friction forces on both sides of the tire, preventing uneven friction forces that could lead to sideslip. In addition, part of the guide groove 2 is aligned with the equator and forms an acute angle with it. Taking the illustration as an example, from top to bottom, the width of some of the patterns increases. When rolling, the increasing groove width can quickly gather and collect a large volume of water flow, allowing the tire tread to quickly grip the ground and provide stable friction.

[0022] At least two diverting lines 22 converge at one end of the converging line 21. Each diverting line 22 has at least partially parallel portions 221 and intersecting transition portions 222. The parallel portions 221 connect to the converging line 21 through the transition portions 222. The overall tree-like guiding lines 2 can quickly, stably, and smoothly guide water from both sides of the equator to both sides of the tire, maintaining a smooth and stable friction force from the equator to both sides of the tire. The two parallel portions 221 can continue to smoothly and stably deliver water to both sides of the tire along the rolling trend, resulting in high drainage efficiency and ensuring stable grip.

[0023] In one embodiment, a guide portion 223 connects the converging groove 21 and the transition portion 222. The guide portion 223 and the parallel portion 221 are parallel to each other on the tread layer 1, and the groove widths of the guide portion 223 and the parallel portion 221 are the same. The water flow direction in the guide portion 223 is consistent with the water flow direction in the parallel groove, which allows the water to flow smoothly to both sides of the tire after converging. The parallel portions 221 on both sides can also collect the water flow corresponding to the parallel portion 221 again, discharge it smoothly again according to the pre-flow trend, and finally discharge it to the outside, improving the tire's grip.

[0024] In one embodiment, the tread layer 1 is further provided with sound-absorbing patterns spaced apart from the guide lines 2. The sound-absorbing patterns include at least one circular hole 31 and stripes communicating with the circular hole 31. With one or more circular holes 31 and stripes formed on the tread layer 1, when the tire generates noise, the noise is transmitted along the length of the stripes and ultimately reaches the circular hole 31. The noise is absorbed by the annular inner wall of the circular hole 31, thereby reducing tire noise.

[0025] In one embodiment, the sound-absorbing pattern 3 includes a strip-shaped pattern and a circular hole 31 connected to one end of the strip-shaped pattern. In practice, the sound-absorbing pattern comprises two parts, a circular hole 31 and a strip-shaped hole 32. During operation, noise generated on the tire can be stably absorbed through the circular hole 31 at one end, thereby reducing tire noise.

[0026] In one embodiment, the sound-absorbing pattern 3 includes two stripes forming an obtuse angle, with circular holes 31 at the junction of the inflection points and at both ends. Alternatively, it may include two stripes and three circular holes 31, with noise transmitted through the stripes and ultimately absorbed stably through the circular holes 31 at the inflection points, thus reducing tire noise.

[0027] In one embodiment, in the thickness direction, a reinforcing layer 4 and an inner layer 5 are sequentially disposed at the bottom of the tread layer 1. The inner layer 5 is outwardly fitted at the connection point with the wheel hub, and the inner layer 5 is covered with a steel wire ring 6. An outwardly flipped inner layer 5 is also connected at the bottom of the tread layer 1. The edges of the inner layer 5 are outwardly flipped and fitted, and the steel wire can provide stable support for the tire sidewall.

[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.
