Description

Technical Field

[0001] This utility model relates to the field of tires, and in particular to an anti-skid tire. Background Technology

[0002] In rainy driving scenarios, the water film formed on the road surface significantly reduces the friction between the tire and the road, resulting in decreased tire grip, increased braking distance, and a higher risk of skidding and loss of control at high speeds. The wet performance of rubber tires mainly depends on drainage efficiency and tread design. Traditional tires improve drainage capacity by adding longitudinal or lateral grooves, but it is difficult to balance drainage speed with structural strength.

[0003] A tire designed to improve wet traction has been disclosed. It utilizes a multi-regional groove design—a first drainage groove in the center of the tread, steel groove areas on both sides, and a second drainage groove—to evenly drain rainwater and prevent localized water accumulation that could affect handling stability. The principle is to guide water flow circumferentially through a network of grooves, reducing water film retention. However, this solution has limitations: while the groove structure effectively guides water flow, the drainage path is relatively long. Especially during heavy rain, the water flow struggles to quickly overcome the adhesion between the tire tread and the road surface, resulting in insufficient actual contact area and limited improvement in wet traction.

[0004] Therefore, there is an urgent need to introduce more efficient anti-skid structures to improve the real-time drainage efficiency of tires under different rainfall levels and enhance the safety of handling in wet conditions. Utility Model Content

[0005] The purpose of this invention is to solve the technical problems of low drainage efficiency in existing tires, which prevent the tire from breaking through the water film and making full contact with the ground, resulting in extended braking distance and slippage and loss of control during emergency braking. This invention provides an anti-slip tire that can improve the drainage efficiency of vehicles during rainy weather, effectively reduce the probability of water film formation between the tire and the road surface, reduce the risk of hydroplaning, and provide reliable technical protection for driving safety in rainy weather.

[0006] To solve the above-mentioned technical problems, the present invention discloses an anti-skid tire, the anti-skid tire comprising:

[0007] The tire body includes a tread and shoulders, and along the axial direction, the shoulders are located on both sides of the tread.

[0008] Multiple drainage channels are provided at circumferential intervals on the tire shoulder;

[0009] Multiple vertical grooves are spaced apart along the axial direction on the tire tread, and each vertical groove extends around the circumference.

[0010] Multiple first inclined grooves are spaced apart on the tire tread. The extension direction of the multiple first inclined grooves intersects the axial direction. Both ends of each first inclined groove are connected to the drainage groove and intersect with the multiple vertical grooves respectively.

[0011] Multiple second inclined grooves are spaced apart on the tire tread. The extension direction of the multiple second inclined grooves intersects the axial direction and the extension direction of the multiple first inclined grooves. Both ends of each second inclined groove are connected to the drainage groove. When each second inclined groove intersects with its corresponding first inclined groove, it also intersects with the vertical groove.

[0012] Using the above technical solution, when the anti-skid tire is driven in the rain, rainwater is drawn into the multiple vertical grooves on the tire tread during contact with the ground. The rainwater entering the vertical grooves follows a dual-path discharge mechanism: part of the rainwater is directly thrown out of the tire from the vertical groove under the centrifugal force generated by the high-speed rotation of the tire, shortening the rainwater retention time; the other part is transported to the drainage channel through the first or second inclined groove connecting the vertical grooves, and the rainwater is discharged from the tire using the guiding structure of the drainage channel.

[0013] Compared to traditional single-path drainage structures, this technical solution improves the drainage efficiency of vehicles during rainy weather, effectively reduces the probability of water film formation between tires and the road surface, lowers the risk of hydroplaning, and provides reliable technical protection for driving safety in rainy weather.

[0014] According to another specific embodiment of the present invention, each of the first inclined grooves and each of the second inclined grooves are provided with a plurality of inclined groove protrusion groups to form an inclined groove drainage channel. The width of the inclined groove drainage channel is smaller than the width of the first inclined groove and smaller than the width of the second inclined groove. Along the circumferential direction, the position of each inclined groove protrusion group is offset from the vertical groove.

[0015] The above technical solution involves installing sloping spur groups on both the first and second sloping spurs, primarily to optimize water flow guidance efficiency. These sloping spur groups cut into the water film, disrupting surface tension and causing the water flow to break up. Their geometric shape forms a guiding slope, forcibly altering the water flow path and shortening the guidance time. Simultaneously, they induce turbulence, increasing the kinetic energy of the water and accelerating the flow using the Venturi effect. This solution addresses the inefficient water flow guidance problem of the first and second sloping spurs and drainage channels, especially in low-to-medium vehicle speeds or deep water scenarios. It reduces rainwater retention, lowers the risk of water film formation, and improves tire handling safety in wet conditions.

[0016] According to another specific embodiment of the present invention, the inclined groove protrusion group includes a first inclined groove protrusion and a second inclined groove protrusion. The first inclined groove protrusion is used to connect with one side of the first inclined groove and one side of the second inclined groove. The second inclined groove protrusion is used to connect with the other side of the first inclined groove and the other side of the second inclined groove. Along the direction perpendicular to the extension of the first inclined groove, the first inclined groove protrusion and the second inclined groove protrusion are corresponding and spaced apart. Along the direction perpendicular to the extension of the second inclined groove, the first inclined groove protrusion and the second inclined groove protrusion are corresponding and spaced apart to form the inclined groove drainage channel.

[0017] Using the above technical solution, the first inclined groove protrusion and the second inclined groove protrusion form an inclined groove drainage channel. That is, the water flow channel is narrow in the middle and wide on both sides. The cross-sectional area of ​​the inclined groove drainage channel is reduced and the water pressure is increased. At this time, the rainwater located in the first or second inclined groove will flow quickly and accelerate to the drainage channel. Then, the rainwater is discharged from the tire through the drainage channel, thereby reducing the possibility of forming a water film between the tire and the road surface and improving the tire's anti-skid performance.

[0018] According to another specific embodiment of the present invention, the first inclined groove protrusion and the second inclined groove protrusion are respectively arc-shaped blocks.

[0019] According to another specific embodiment of the present invention, each of the vertical grooves is provided with a plurality of vertical groove protrusion groups to form a vertical groove drainage channel. The width of the vertical groove drainage channel is smaller than the width of the vertical groove, and the position of each vertical groove protrusion group is offset from the first inclined groove and the second inclined groove.

[0020] The above technical solution involves installing a set of vertical groove protrusions on the vertical groove, primarily to optimize water flow guidance efficiency. These protrusions cut into the water film, disrupting surface tension and causing the water flow to break up. Their geometric shape forms a guiding slope, forcibly altering the water flow path and shortening the guidance time. Simultaneously, they induce turbulence, increasing the kinetic energy of the water and accelerating the flow using the Venturi effect. This solution addresses the inefficient water flow guidance problem of the vertical groove and the first and second inclined grooves, especially in low-to-medium vehicle speeds or deep water scenarios. It reduces rainwater retention, lowers the risk of water film formation, and improves tire handling safety in wet conditions.

[0021] According to another specific embodiment of the present invention, the vertical groove protrusion group includes a first vertical groove protrusion and a second vertical groove protrusion. The first vertical groove protrusion is connected to one side of the vertical groove, and the second vertical groove protrusion is connected to the other side of the vertical groove. Along the axial direction, the first vertical groove protrusion and the second vertical groove protrusion are corresponding to each other and spaced apart to form the vertical groove drainage channel.

[0022] Using the above technical solution, the first vertical groove protrusion and the second vertical groove protrusion form a vertical groove drainage channel. That is, the water flow channel is narrow in the middle and wide on both sides. The cross-sectional area of ​​the vertical groove drainage channel is reduced and the water pressure is increased. At this time, the rainwater in the vertical groove will flow quickly and accelerate to the first inclined groove and the second inclined groove. Then, the rainwater is discharged from the tire through the drainage groove, thereby reducing the possibility of water film forming between the tire and the road surface and improving the tire's anti-skid performance.

[0023] According to another specific embodiment of the present invention, the first vertical groove protrusion and the second vertical groove protrusion are respectively arc-shaped blocks.

[0024] According to another specific embodiment of the present invention, the anti-slip tire includes a plurality of protrusions, which are respectively disposed at the communication points of the first inclined groove, the second inclined groove and the vertical groove.

[0025] By adopting the above technical solution, the protrusion can prevent large stones and other debris from getting stuck at the connection between the first inclined groove, the second inclined groove and the vertical groove, thus hindering the flow of rainwater.

[0026] According to another specific embodiment of the present invention, the anti-slip tire includes a plurality of separators, each separator being disposed at the interval of the plurality of inclined groove protrusion groups or at the interval of the plurality of vertical groove protrusion groups. Each separator includes a plurality of tire hair groups spaced apart along the circumferential direction, and each tire hair group includes a plurality of tire hairs spaced apart along the axial direction. The tire hairs are used for contact with the external ground to improve the grip of the anti-slip tire.

[0027] Using the above technical solution, tire hairs can improve the grip of tires in wet conditions. On wet roads, tire hairs can pierce the surface tension of the water film, forming micro-contact points and assisting in the separation of the water film. Under normal circumstances, tire driving will wear down the tire hairs. When the outermost layer of tire hairs is worn down, the next layer of tire hairs can continue to contact the ground to improve grip. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0052] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0053] refer to Figures 1 to 2B This application provides an anti-skid tire, which includes a tire body 10, a plurality of drainage grooves 20, a plurality of vertical grooves 30, a plurality of first inclined grooves 40 and a plurality of second inclined grooves 50. The tire body 10 includes a tread 11 and a shoulder 12. Along the axial direction X, the shoulder 12 is provided on both sides of the tread 11.

[0054] Multiple drainage grooves 20 are spaced along the circumferential direction R on the tire shoulder 12, and multiple vertical grooves 30 are spaced along the axial direction X on the tire tread 11, with each vertical groove 30 extending one circle along the circumferential direction R.

[0055] Multiple first inclined grooves 40 are spaced apart on the tread 11. The extension direction of the multiple first inclined grooves 40 (as shown by C1 in Figure 2) intersects the axial direction X. The two ends of each first inclined groove 40 are connected to the drainage groove 20 and intersect with multiple vertical grooves 30 respectively.

[0056] Multiple second inclined grooves 50 are spaced apart on the tread 11. The extending directions of the multiple second inclined grooves 50 (as shown by C2 in Figure 2) intersect the axial direction X and the extending directions of the multiple first inclined grooves 40. Both ends of each second inclined groove 50 are connected to the drainage groove 20. When each second inclined groove 50 intersects with its corresponding first inclined groove 40, it also intersects with the vertical groove 30.

[0057] Using the above technical solution, when the anti-skid tire is driven in the rain, rainwater will be introduced into the multiple vertical grooves 30 on the tread 11 during contact with the ground. The rainwater entering the vertical grooves 30 has a dual-path discharge mechanism: part of the rainwater is directly thrown out of the tire from the vertical grooves 30 under the centrifugal force generated by the high-speed rotation of the tire, shortening the rainwater retention time; the other part is transported to the drainage trough 20 through the first inclined groove 40 or the second inclined groove 50 connecting the vertical grooves 30, and the rainwater is discharged from the tire by the guiding structure of the drainage trough 20.

[0058] Compared to traditional single-path drainage structures, this technical solution improves the drainage efficiency of vehicles during rainy weather, effectively reduces the probability of water film formation between tires and the road surface, lowers the risk of hydroplaning, and provides reliable technical protection for driving safety in rainy weather.

[0059] It should be noted that the number of drainage channels 20 is not specifically limited in this embodiment. For example, in other possible implementations, the number of drainage channels 20 may be twenty-four, twenty-eight, thirty-two, etc. The number of vertical channels 30 is not specifically limited in this embodiment. For example, in other possible implementations, the number of vertical channels 30 may be four, five, six, etc. The number of first inclined channels 40 is not specifically limited in this embodiment. For example, in other possible implementations, the number of first inclined channels 40 may be fifteen, sixteen, seventeen, etc. The number of second inclined channels 50 is not specifically limited in this embodiment. For example, in other possible implementations, the number of second inclined channels 50 may be fifteen, sixteen, seventeen, etc.

[0060] In some possible implementations, refer to Figures 2A to 3 Each first inclined groove 40 and each second inclined groove 50 is provided with six inclined groove protrusion groups 60 to form an inclined groove drainage channel 61. The width D1 of the inclined groove drainage channel 61 is smaller than the width L1 of the first inclined groove 40 and smaller than the width L2 of the second inclined groove 50. Along the circumferential direction R, the position of each inclined groove protrusion group 60 is offset from the vertical groove 30.

[0061] The above technical solution involves installing sloping spur protrusion groups 60 on the first sloping spur 40 and the second sloping spur 50, primarily to optimize water flow guidance efficiency. The sloping spur protrusion groups 60 cut into the water film, disrupting surface tension and causing the water flow to break up. Their geometric shape forms a guiding slope, forcibly altering the water flow path and shortening the guidance time. Simultaneously, they induce turbulence, increasing the kinetic energy of the water flow and accelerating it using the Venturi effect. This solution addresses the inefficient water flow guidance of the first sloping spur 40, the second sloping spur 50, and the drainage ditch 20. Especially in low-to-medium vehicle speeds or deep water scenarios, it reduces rainwater retention, lowers the risk of water film formation, and improves tire handling safety in wet conditions.

[0062] It should be noted that the number of the inclined groove bump group 60 is not specifically limited in this embodiment. For example, in other possible implementations, the number of inclined groove bump group 60 may be five, seven, eight, etc.

[0063] In some possible implementations, refer to Figures 2A to 3 The inclined groove protrusion assembly 60 includes a first inclined groove protrusion 62 and a second inclined groove protrusion 63. The first inclined groove protrusion 62 is used to connect with one side of the first inclined groove 40 and one side of the second inclined groove 50, and the second inclined groove protrusion 63 is used to connect with the other side of the first inclined groove 40 and the other side of the second inclined groove 50, along a direction perpendicular to the extension of the first inclined groove 40 (e.g., Figure 3 As shown in Y1), a groove protrusion on the first groove 40 corresponds to and is spaced apart from the second groove protrusion 63, extending in a direction perpendicular to the second groove 50 (e.g., ...). Figure 3 As shown in Y2), the first inclined groove protrusion 62 and the second inclined groove protrusion 63 are provided on the second inclined groove 50 and are arranged at intervals to form the inclined groove drainage channel 61.

[0064] Using the above technical solution, the first inclined groove protrusion 62 and the second inclined groove protrusion 63 form an inclined groove drainage channel 61. That is, the water flow channel is narrow in the middle and wide on both sides. The cross-sectional area of ​​the inclined groove drainage channel 61 is reduced and the water pressure is increased. At this time, the rainwater located in the first inclined groove 40 or the second inclined groove 50 will flow quickly and accelerate to the drainage groove 20. Then, the rainwater is discharged from the tire through the drainage groove 20, thereby reducing the possibility of forming a water film between the tire and the road surface and improving the tire's anti-skid performance.

[0065] In some possible implementations, refer to Figures 2A to 3 The first inclined groove protrusion 62 and the second inclined groove protrusion 63 are arc-shaped blocks.

[0066] It should be noted that the shapes of the first inclined groove protrusion 62 and the second inclined groove protrusion 63 are not specifically limited in this embodiment. For example, in other possible implementations, the shapes of the first inclined groove protrusion 62 and the second inclined groove protrusion 63 can be triangles, polygons, etc.

[0067] In some possible implementations, refer to Figures 2A to 3 Each vertical groove 30 is provided with multiple vertical groove protrusion groups 70 to form a vertical groove drainage channel 71. The width D2 of the vertical groove drainage channel 71 is less than the width L3 of the vertical groove 30. The position of each vertical groove protrusion group 70 is offset from the first inclined groove 40 and the second inclined groove 50.

[0068] The above technical solution involves setting a vertical groove protrusion group 70 on the vertical groove 30, primarily to optimize water flow guidance efficiency. The vertical groove protrusion group 70 cuts into the water film, disrupting surface tension and causing the water flow to break up. Its geometric shape forms a guiding slope, forcibly changing the water flow path and shortening the guidance time. Simultaneously, it induces turbulence, increasing the kinetic energy of the water flow and accelerating it using the Venturi effect. This solves the problem of inefficient water flow guidance in the vertical groove 30 and the first inclined groove 40 and second inclined groove 50, especially in scenarios with low to medium vehicle speeds or deep water accumulation. It reduces rainwater retention, lowers the risk of water film formation, and improves tire handling safety in wet conditions.

[0069] It should be noted that the number of vertical groove protrusion groups 70 is not specifically limited in this application embodiment. For example, in other possible implementations, the number of vertical groove protrusion groups 70 can be fifteen, sixteen, seventeen, eighteen, etc.

[0070] In some possible implementations, refer to Figures 2A to 3 The vertical groove protrusion group 70 includes a first vertical groove protrusion 72 and a second vertical groove protrusion 73. The first vertical groove protrusion 72 is connected to one side of the vertical groove 30, and the second vertical groove protrusion 73 is connected to the other side of the vertical groove 30. Along the axial direction X, the first vertical groove protrusion 72 and the second vertical groove protrusion 73 are corresponding and spaced apart to form a vertical groove drainage channel 71.

[0071] Using the above technical solution, the first vertical groove protrusion 72 and the second vertical groove protrusion 73 form a vertical groove drainage channel 71. That is, the water flow channel is narrow in the middle and wide on both sides. The cross-sectional area of ​​the vertical groove drainage channel 71 is reduced and the water pressure is increased. At this time, the rainwater in the vertical groove 30 will flow quickly and accelerate to the first inclined groove 40 and the second inclined groove 50. Then, the rainwater is discharged from the tire through the drainage groove 20, thereby reducing the possibility of forming a water film between the tire and the road surface and improving the tire's anti-skid performance.

[0072] In some possible implementations, refer to Figures 2A to 3 The first vertical groove protrusion 72 and the second vertical groove protrusion 73 are arc-shaped blocks.

[0073] It should be noted that the shapes of the first vertical groove protrusion 72 and the second vertical groove protrusion 73 are not specifically limited in this embodiment. For example, in other possible implementations, the shapes of the first vertical groove protrusion 72 and the second vertical groove protrusion 73 can be triangles, polygons, etc.

[0074] In some possible implementations, refer to Figures 2A to 3 The anti-skid tire includes multiple protrusions 80, which are respectively located at the connection points of the first inclined groove 40, the second inclined groove 50 and the vertical groove 30.

[0075] By adopting the above technical solution, the protrusion 80 can prevent large stones and other debris from getting stuck at the connection between the first inclined groove 40, the second inclined groove 50 and the vertical groove 30, thus preventing rainwater from flowing through.

[0076] It should be noted that the number of protrusions 80 is not specifically limited in this application embodiment. For example, in other possible implementations, the number of protrusions 80 may be eleven, twelve, thirteen, etc.

[0077] In some possible implementations, refer to Figure 2A and Figure 4 The anti-skid tire includes multiple separators 90, each separator 90 being located at the intervals of multiple inclined groove protrusion groups 60, or at the intervals of multiple vertical groove protrusion groups 70. Each separator 90 includes three circumferentially spaced tire hair groups 91, meaning there is a gap 92 between adjacent tire hair groups 91. Each tire hair group 91 includes ten axially spaced tire hairs 911, which are used for contact with the external ground to improve the grip of the anti-skid tire.

[0078] Using the above technical solution, the tire hair 911 can improve the grip of wet tires. On wet roads, the tire hair 911 can puncture the surface tension of the water film, forming micro-contact points to help break the water film. Under normal circumstances, tire driving will wear down the tire hair 911. When the outermost tire hair group 91 is worn down, the next tire hair group 91 can continue to contact the ground to improve grip.

[0079] It should be noted that the number of separators 90 is not specifically limited in this embodiment. For example, in other possible implementations, the number of separators 90 may be forty-five, forty-eight, fifty-one, etc. Similarly, the number of lanugo groups 91 included in each separator 90 is not specifically limited in this embodiment. For example, in other possible implementations, the number of lanugo groups 91 included in each separator 90 may be four, five, six, etc. Likewise, the number of lanugo 911 included in each lanugo group 91 is not specifically limited in this embodiment. For example, in other possible implementations, the number of lanugo 911 included in each lanugo group 91 may be nine, eleven, twelve, etc.

[0080] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
