Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire technology, and in particular to a winter electric motorcycle tire. Background Technology
[0002] As a core safety component on an electric motorcycle that is in direct contact with the ground, tires bear the core functions of vehicle load transfer, power output, braking response, and steering operation. Their performance directly determines the vehicle's handling stability, ride comfort, and driving safety.
[0003] In complex winter road conditions, the market demands increasingly higher standards for tires, especially in terms of cold resistance, stability, and driving safety. Therefore, it is necessary to design and develop tires adapted to winter road conditions. When turning on icy or cold terrain or braking on muddy surfaces, tires are prone to slipping and drifting.
[0004] Therefore, a winter electric motorcycle tire is still needed to solve the above problems. Utility Model Content
[0005] This utility model provides a winter electric motorcycle tire that solves the above-mentioned problems.
[0006] The objective of this utility model is achieved through the following technical solution:
[0007] A winter electric motorcycle tire includes a tread layer, on which a first irregularly shaped block, a second irregularly shaped block, and a third irregularly shaped block are sequentially formed at the same position perpendicular to the equator. The third irregularly shaped block is located on the equator and is symmetrically designed about the equator as an axis of symmetry. At least one side of the first irregularly shaped block is flush with the edge of the tread layer. The first irregularly shaped block, the second irregularly shaped block, and the third irregularly shaped block are separated by a spacer groove.
[0008] In one embodiment, a first secondary groove is formed on the first irregular block, one end of the first secondary groove is connected to the edge of the tread layer, and the other end is connected to the spacer groove. The first secondary groove is corrugated. The top and bottom edges of the first irregular block are both straight lines perpendicular to the equator. At least two parallel non-overlapping straight lines are formed on the side of the first irregular block near the spacer groove.
[0009] In one embodiment, the number of first secondary grooves on each of the first irregular blocks is three.
[0010] In one embodiment, the depth of the spacer groove is 4.5 mm.
[0011] In one embodiment, at least two parallel and non-overlapping straight edges are formed on the side of the second irregular block near the first irregular block, and at least two parallel and non-overlapping straight edges are formed on the side of the third irregular block.
[0012] In one embodiment, a second secondary groove is formed on the second irregular block, and the second secondary groove forms a stepped distribution on the surface of the second irregular block, dividing the surface of the second irregular block into a plurality of second blocks with stepped edges.
[0013] In one embodiment, the third irregular block is divided into a first patterned area, a second patterned area, and a third patterned area by a straight line parallel to the equator. The patterns in the first and third patterned areas are symmetrical about the equator, and a portion of the third secondary grooves in the second patterned area are distributed along the equator.
[0014] The bottom of the tread layer also includes a reinforcement layer and an inner layer.
[0015] Compared with the prior art, the beneficial effects of this utility model include at least the following:
[0016] The tread layer has three independently protruding irregularly shaped blocks arranged in the transverse direction. The first irregularly shaped blocks are symmetrically distributed to provide stable grip. The irregularly shaped first, second, and third irregularly shaped blocks serve as large tread particles in contact with the ground, effectively conforming to complex road conditions and dispersing stress. The large tread particles have good grip and guiding performance, greatly improving driving performance, especially on icy or low-temperature roads. The first and second irregularly shaped blocks are symmetrically distributed on both sides of the third irregularly shaped block, gripping the ground in segments for a high level of grip.

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.

[0022] Reference Figure 1-2 This utility model provides a winter electric motorcycle tire, including a tread layer 1. On the tread layer 1, at the same position perpendicular to the equator, a first irregularly shaped block 11, a second irregularly shaped block 12, and a third irregularly shaped block 13 are sequentially formed. The third irregularly shaped block 13 is located on the equator and is symmetrically designed about the equator as an axis of symmetry. At least one side of the first irregularly shaped block 11 is flush with the edge of the tread layer 1. The first irregularly shaped block 11, the second irregularly shaped block 12, and the third irregularly shaped block 13 are separated by a spacer groove 14. There are two of the first irregularly shaped blocks 11 and two of the second irregularly shaped blocks 12, which are symmetrically distributed about the equator. The shapes of the first irregularly shaped blocks 11, the second irregularly shaped block 12, and the third irregularly shaped block 13 are all different. The tread layer 1 serves as the surface layer of the tire that contacts the ground. The center line of the tire layer is the equator. The first irregular block 11, the second irregular block 12, and the third irregular block 13 are all polygonal irregular structures. The first irregular block 11 and the second irregular block 12 are symmetrically designed on both sides of the third irregular block 13. The second irregular block 12 also has an approximately Z-shaped structure design. The tread pattern is designed with irregular blocks and fine stripes, which makes the tire more wear-resistant and grippy, and improves the comfort and safety of the product. In addition, the shapes of the first irregular block 11, the second irregular block 12, and the third irregular block 13 are all different. The edges of the first irregular block 11 and the tire edge are smoothly connected in straight lines. The shape of the third irregular block 13 is symmetrically designed along the axis, and the third irregular block 13 as a whole is stacked into an approximate gourd shape. The top 1 / 2 structure is an approximate trapezoidal structure, and the bottom 1 / 2 structure is similar to the top 1 / 2 structure. When in contact with the ground, the large tread particles can first grip the ground, and then gradually reduce the contact area during rolling, thereby increasing the pressure and making the gripping position more secure, so as to improve the driving control during rolling and prevent the tire from slipping.
[0023] In one embodiment, a first secondary groove 111 is formed on the first shaped block 11. One end of the first secondary groove 111 is connected to the edge of the tread layer 1, and the other end is connected to the spacer groove 14. The first secondary groove 111 is corrugated. The top and bottom edges of the first shaped block 11 are straight lines perpendicular to the equator. At least two parallel, non-overlapping straight lines are formed on the side of the first shaped block 11 near the spacer groove 14. The shape of the first secondary groove 111 is shown in the figure. The groove on the left side is higher, and the groove on the right side is lower, and it is a continuous corrugated shape. The depth of the first spacer groove 14 is lower than that of the spacer groove 14. This design ensures the overall rigidity of the first tread block at the edge and allows for more flexible movement of the tire crown, facilitating deformation and grip.
[0024] In one embodiment, each of the first irregularly shaped blocks 11 has three first secondary grooves 111. The first secondary grooves 111 on the first irregularly shaped block 11 divide the surface of the first irregularly shaped block 11 into four parts, which can effectively break through the snow layer, improve driving safety, and is both aesthetically pleasing and safe.
[0025] In one embodiment, the depth of the spacer groove 14 is 4.5 mm.
[0026] In one embodiment, at least two parallel and non-overlapping straight edges are formed on the side of the second irregular block 12 near the first irregular block 11, and at least two parallel and non-overlapping straight edges are formed on the side of the second irregular block 12 near the side slots 14. The straight edges formed on the second irregular block 12 near the side slots 14 can stably allow water to flow smoothly away from the tire surface, preventing it from accumulating at the bottom and causing the first irregular block 11, the second irregular block 12, and the third irregular block 13 to lose grip.
[0027] In one embodiment, a second secondary groove 121 is formed on the second irregular block 12. The second secondary groove 121 forms a stepped distribution on the surface of the second irregular block 12, dividing the surface of the second irregular block 12 into multiple second blocks with stepped edges. The second secondary groove 121 is generally oriented towards the equator and inclined upward on the second irregular block 12, and has a continuous wavy shape, which greatly improves riding grip and comfort.
[0028] In one embodiment, the third irregularly shaped block 13 is divided into a first tread zone 2, a second tread zone 3, and a third tread zone 4 by a straight line parallel to the equator. The patterns of the first tread zone 2 and the third tread zone 4 are symmetrical about the equator. A portion of the third secondary grooves 131 in the second tread zone 3 are arrayed along the equator. A virtual line parallel to the equator divides the tread pattern into parallel first tread zones 2, 2, 3, and 3. The shapes of the first tread zones 2 and 3 are symmetrical about the equator. The upper third secondary groove 131 of the first tread zone 2 has an overall ring-shaped structure. When the third irregularly shaped block 13 contacts the ground, multiple surfaces on the third irregularly shaped block 13 can interlock, increasing grip. The bottom of the tread layer 1 also includes a reinforcing layer 5 and an inner layer 6.
[0029] 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.
