Description

Technical Field

[0001] This utility model belongs to the field of tire design, and in particular relates to a tire with drainage properties. Background Technology

[0002] With consumers increasingly demanding higher standards for driving safety and experience, HT (Highway Terrain) tires, which balance on-road comfort with a certain degree of off-road capability, are experiencing steady market demand growth. Especially in regions with rainy and slippery road conditions, such as Western Europe, Southeast Asia, and southern my country, consumers are highly focused on the water drainage performance of HT tires. This provides a vast market space for HT tire tread designs with excellent water drainage performance and for the development of HT tires in general.

[0003] However, although some existing HT tire patterns have improved drainage performance, there are still situations where drainage is not timely in heavy rain or on roads with deep water, which can easily lead to hydroplaning risks. Utility Model Content

[0004] Details of one or more embodiments of the present invention are set forth in the following drawings and description to make other features, objects and advantages of the present application more readily apparent.

[0005] This invention proposes a tire with drainage properties, which solves the technical problems of untimely drainage and insufficient performance compatibility of existing HT tires, and features rapid drainage and balanced performance.

[0006] This utility model discloses a water-draining tire, comprising a central tread block extending along the circumferential centerline of the tire tread, intermediate tread blocks symmetrically arranged on both sides of the central tread block, and shoulder tread blocks located on the side of the intermediate tread blocks away from the central tread block; longitudinal grooves are defined between the boundaries of the shoulder tread blocks and the intermediate tread blocks, and between the boundaries of the intermediate tread blocks and the central tread block; the boundary of the shoulder tread block near the intermediate tread block is a continuous boundary formed by a periodic arrangement of concave-straight-convex-straight units along the circumferential direction of the tire tread; the intermediate tread blocks are formed by a periodic arrangement of intermediate tread block units along the circumferential direction of the tire tread, and a first transverse groove connecting the longitudinal grooves at both ends is provided between adjacent intermediate tread block units; the intermediate tread block units are formed by a first intermediate tread block and a second intermediate tread block arranged along the circumferential direction of the tire tread, and the first and second intermediate tread blocks are radially staggered along the tire tread; the two sides of the central tread block are boundaries formed by a periodic arrangement of convex-straight units along the circumferential direction of the tire tread.

[0007] In some embodiments, the first transverse groove is zigzag-shaped and consists of a first part near the shoulder tread block, a second part near the central tread block, and a third part connecting the first and second parts. The depth of the first part is less than the depth of the second and third parts, and the depth of the third part increases from the first part to the third part.

[0008] In some embodiments, a second transverse groove is provided between the first intermediate patterned block and the second intermediate patterned block, with the two ends connected by longitudinal grooves.

[0009] In some embodiments, the depth of the second lateral groove near the shoulder tread block is greater than the depth of the second lateral groove near the central tread block.

[0010] In some embodiments, the width of the second lateral groove near the shoulder tread block is greater than the width of the second lateral groove near the central tread block.

[0011] In some embodiments, the central patterned block has a third transverse groove that connects the longitudinal grooves on both sides of the central patterned block, and the widths of the left and right sides of the third transverse groove are different.

[0012] In some embodiments, the bottom depth of the wider third transverse groove is greater than the bottom depth of the wider third transverse groove.

[0013] In some embodiments, adjacent third transverse grooves are arranged oppositely in the left-right direction on the central pattern block.

[0014] In some embodiments, a fourth transverse groove is provided on the shoulder tread block, with one end of the fourth transverse groove near the middle tread block located on the shoulder tread block.

[0015] In some embodiments, the end of the fourth transverse groove near the middle patterned block is connected to the longitudinal groove by a steel sheet.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides a tire with drainage capabilities. By defining the boundaries of the shoulder tread blocks and the central tread blocks, and the composition of the intermediate tread blocks, a four-groove design with staggered concave and convex longitudinal grooves is formed. This creates a "multi-level drainage channel" in the main grooves. When water flows in the grooves, the concave and convex textures break the laminar flow of water, accelerating the dispersion and discharge of water. Compared to smooth groove walls, the drainage efficiency is improved by more than 25%. Even when heavy rainfall causes a large amount of water to accumulate on the road surface, it can quickly clear the water film between the tire tread and the road surface, reducing the risk of hydroplaning from the root. At the same time, the "micro-texture" of the concave and convex groove walls can reduce the vibration noise of air in the grooves, improving driving comfort. On lightly unpaved roads (such as gravel roads), the concave and convex structure can enhance the tire's grip on the gravel and prevent slippage. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.

[0019] This invention provides a tire with drainage properties. Figure 1 This is a schematic diagram of a water-draining tire according to an embodiment of the present invention. (Reference) Figure 1As shown, the water-draining tire includes a central tread block 101 extending along the circumferential centerline of the tire tread, intermediate tread blocks 102 symmetrically arranged on both sides of the central tread block 101, and a shoulder tread block 103 located on the side of the intermediate tread block 102 away from the central tread block 101; longitudinal grooves 2 are defined between the boundaries of the shoulder tread block 103 and the intermediate tread block 102, and between the boundaries of the intermediate tread block 102 and the central tread block 101; the side boundary of the shoulder tread block 103 near the intermediate tread block 102 is a unit composed of concave-straight-convex-straight along the circumferential direction of the tire tread. The continuous boundary is formed by the periodic arrangement of the intermediate tread blocks 102; the intermediate tread blocks 102 are formed by the periodic arrangement of intermediate tread block 102 units along the circumference of the tire tread, and a first transverse groove 3 connecting the longitudinal grooves 2 at both ends is provided between adjacent intermediate tread block 102 units; the intermediate tread block 102 unit is formed by the arrangement of the first intermediate tread block 1021 and the second intermediate tread block 1022 along the circumference of the tire tread, and the first intermediate tread block 1021 and the second intermediate tread block 1022 are radially staggered along the tire tread; the two side boundaries of the central tread block 101 are the boundary formed by the periodic arrangement of convex-straight units along the circumference of the tire tread.

[0020] The aforementioned drainage-capable tire, by defining the boundaries of the shoulder tread block 103 and the central tread block 101, and the composition of the intermediate tread block 102, forms four staggered longitudinal grooves 2. This design creates a "multi-level drainage channel" in the main grooves. When water flows within the grooves, the uneven texture breaks the laminar flow of water, accelerating the dispersion and discharge of water. Compared to smooth groove walls, drainage efficiency is improved by more than 25%. Even when heavy rainfall causes a large amount of water to accumulate on the road surface, it can quickly clear the water film between the tire tread and the road surface, reducing the risk of hydroplaning from the root. At the same time, the "micro-texture" of the uneven groove walls can reduce the vibration noise of air within the grooves, improving driving comfort. On lightly unpaved roads (such as gravel roads), the uneven structure can enhance the tire's grip on the gravel, preventing slippage.

[0021] In some embodiments, the four longitudinal grooves 2 are misaligned by 1.5 mm.

[0022] like Figure 2 As shown, the first transverse groove 3 is a zigzag shape, consisting of a first part 301 near the shoulder tread block 103, a second part 302 near the central tread block 101, and a third part 303 connecting the first part 301 and the second part 302. The depth of the first part 301 is less than the depth of the second part 302 and the third part 303, and the depth of the third part 303 increases from the first part 301 to the third part 303.

[0023] The first transverse groove 3 adopts a gradient groove depth design, which can form a "step-like drainage channel" when the tire rolls. The accumulated water will flow and be discharged quickly along the gradient trend of the groove depth, avoiding water stagnation in the groove. It can adaptively adjust the drainage efficiency. Compared with the equal depth transverse groove, the drainage speed is increased by more than 20%, effectively reducing the risk of hydroplaning.

[0024] In some embodiments, a second transverse groove 4 is provided between the first intermediate patterned block 1021 and the second intermediate patterned block 1022, with both ends connected to the longitudinal groove 2. For example... Figure 3 As shown, the depth of the bottom of the second transverse groove 4 near the shoulder tread block 103 is greater than the depth of the bottom of the second transverse groove 4 near the central tread block 101. In some embodiments, the width of the second transverse groove 4 near the shoulder tread block 103 is greater than the width of the second transverse groove 4 near the central tread block 101.

[0025] The second transverse groove 4 features a gradient depth design, with a depth of 6mm on the left and a shallower depth of 3mm on the right. This gradient direction is opposite to that of the first transverse groove 3, which has a depth of 4mm on the left and a depth of 7mm on the right. This combined design results in a more balanced stress distribution between the grooves and tread blocks, forming a complementary stress-bearing structure. Compared to a single gradient design, this reduces excessive local wear on the tread blocks, improves the overall tire wear resistance by 20%, and delays the formation of fatigue cracks at the groove edges.

[0026] To further ensure drainage, a third transverse groove 5 is provided on the central patterned block 101, connecting the longitudinal grooves 2 on both sides of the central patterned block 101. The widths of the left and right sides of the third transverse groove 5 are different. Figure 3 As shown, the bottom depth of the wider third horizontal groove 5 is greater than the bottom depth of the wider third horizontal groove 5. In some embodiments, adjacent third horizontal grooves 5 are arranged in opposite directions on the central patterned block 101.

[0027] In some embodiments, a fourth transverse groove 6 is provided on the shoulder tread block 103, and one end of the fourth transverse groove 6 near the middle tread block 102 is located on the shoulder tread block 103. In some embodiments, the end of the fourth transverse groove 6 near the middle tread block 102 is connected to the longitudinal groove 2 by a steel sheet 7.

[0028] The semi-closed fourth lateral groove 6 and steel plate 7 on the shoulder tread block 103 make the stress on the shoulder tread block 103 more even. The steel plate 7 enhances the support of the tread block and reduces the deformation of the tread block when the tire is subjected to lateral forces (such as cornering); the semi-closed lateral groove retains the drainage function while strengthening the integrity of the tread block. The combination of the two increases the grip of the shoulder area by more than 20% and significantly enhances the structural strength, reducing the risk of shoulder delamination and shoulder gap.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
