Description

Technical Field

[0001] This utility model relates to the field of tire technology, and in particular to a tire tread pattern and a tire. Background Technology

[0002] With the rapid development of electric vehicle and electric bicycle (hereinafter referred to as "electric vehicle") technology, the design and manufacturing technology of electric vehicle tires has received increasing attention. The tread design of electric vehicle tires not only relates to the driving safety of the vehicle, but also directly affects the tire's wear resistance, water drainage, and grip performance. Among these, water drainage performance is crucial for preventing slippage in rainy weather, while grip performance directly affects the vehicle's acceleration, braking, and handling stability.

[0003] Related technologies primarily focus on improving overall tire performance by optimizing tread pattern shape, distribution, and depth. For example, some tire treads employ wide lateral grooves to enhance drainage and ensure safety in rainy conditions; others use dense longitudinal or diagonal treads to increase the tire's contact area with the ground, improving grip and handling stability. Current tire tread patterns either prioritize drainage performance, with wide and shallow treads to quickly remove water from the road surface, or emphasize grip performance, with fine and deep treads designed to improve tire friction on dry or wet surfaces. However, it is often difficult to achieve a balance between drainage and grip performance. While wide, shallow grooves effectively drain water, they may reduce the tire's contact area with the ground on dry roads or in scenarios requiring high grip, thus affecting handling stability and braking performance. Conversely, while fine and deep treads improve grip, they are prone to water accumulation in rainy conditions, increasing the risk of slippage.

[0004] Therefore, in order to solve the above problems, it is urgent to develop a tire tread pattern and tire to meet the driving needs under different road conditions. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a tire tread pattern and tire that not only takes into account both longitudinal and lateral drainage and grip performance, but also accelerates drainage speed based on a unique tread structure design, thereby increasing the contact area and grip on wet roads.

[0006] The technical solution adopted by this utility model is as follows: a tire tread pattern, used to be arranged on the surface of a tire, comprising:

[0007] At least one main drainage groove is provided along the longitudinal direction of the tire to remove moisture from the tire contact surface;

[0008] Diversion grooves, connected to the main drainage grooves, are used to divert water to the side area of ​​the tire;

[0009] At least one pulse-type groove, connected to the diversion groove, is used to regulate and optimize the water flow;

[0010] At least one connecting groove for connecting pulsed grooves arranged at different positions along the longitudinal direction of the tire;

[0011] At least one outlet is connected to the pulse groove for discharging water to the outside of the tire.

[0012] In one embodiment, the main drainage ditch structure includes a drainage ditch body, and at least one drainage ditch protrusion is provided inside the drainage ditch body;

[0013] Furthermore, the structure of the drainage ditch protrusion is at least one of the following: semi-circular shape, semi-elliptical shape, and arc shape.

[0014] In one embodiment, the diversion grooves are distributed on both sides of the main drainage ditch, diverting water in the middle of the main drainage ditch to both sides and connecting to the tire shoulder.

[0015] Furthermore, the diversion trenches are distributed in a strip shape.

[0016] In one embodiment, the pulsed trench is further provided with a flow guiding structure located in the middle of the pulsed trench, and the flow guiding structure is a central flow guiding plate;

[0017] Furthermore, the central deflector is elliptical in shape;

[0018] Alternatively, the central deflector can be formed by the intersection of two circular arcs.

[0019] In one embodiment, the outlet is located at the end of the pulse groove and at the tire shoulder, with the outlet opening expanding outward to improve drainage efficiency.

[0020] Another type of tire is provided, which has a tire tread pattern as described above.

[0021] The beneficial effects of this utility model are as follows:

[0022] This utility model has a compact structure. By setting up the main body of the drainage groove and the drainage groove protrusions in synergy, it improves drainage efficiency based on the Venturi effect. This design can quickly remove water between the tire and the ground in rainy weather, maintain the effective contact area between the tire and the ground, thereby shortening the braking distance and improving driving safety. At the same time, the drainage groove protrusions not only improve drainage efficiency, but also disrupt the sound wave frequency in the groove, decomposing the sound waves in the groove into low-frequency sound waves that are not easily heard, effectively reducing the noise generated by the tire when driving and improving driving comfort.

[0023] This utility model also has the following advantages:

[0024] (1) This utility model diverts the water from the main drainage ditch to both sides of the tire and through to the tire shoulder, effectively increasing the tire's contact area on wet roads and reducing the risk of slipping.

[0025] (2) The present invention provides a water outlet at the end of the pulse trench, and the water outlet opens outward, which further optimizes the drainage path and improves the drainage efficiency.

[0026] (3) This utility model, through the synergistic effect of pulsed grooves and a central guide plate, balances and optimizes water flow, significantly enhancing the tire's grip and adhesion in wet and complex conditions. This design allows the tire to maintain good handling stability and braking performance on both dry and slippery surfaces;

[0027] (4) The present invention provides connecting grooves between the pulse grooves arranged at different positions along the longitudinal direction of the tire, and the connecting grooves are lightning-shaped, which can easily break the water film and accelerate the drainage on both sides, further improving the tire's grip performance on wet roads.

[0040] See Figure 1 , Figure 1 The diagram shows the overall structure of a tire tread pattern in one embodiment of this application. The tire tread pattern provided in one embodiment of this application includes a main drainage groove 1, a diversion groove 2, a pulse groove 3, a central guide plate 4, a connecting groove 5, and a water outlet 6.

[0041] Combination Figures 1-2 , Figure 2 A schematic diagram of the main drainage groove in this utility model is shown; in some embodiments, the main drainage groove 1 is arranged along the longitudinal direction of the tire, and the main function of the main drainage groove 1 is to drain water from the tire contact surface.

[0042] Furthermore, the structure of the main drainage ditch 1 includes a drainage ditch body 101 and a drainage ditch protrusion 102. The drainage ditch body 101 constitutes the main channel of the drainage ditch, while the drainage ditch protrusion 102 is located inside the drainage ditch body 101.

[0043] Furthermore, the shape of these drainage groove protrusions 102 can be semi-circular, semi-elliptical, or curved, etc., and their design is based on the Venturi effect to improve drainage efficiency. When the tire is driving on a wet road surface, the drainage groove protrusions 102 can disrupt the water flow and increase the water flow speed, thereby more effectively removing accumulated water.

[0044] In some embodiments, the diversion groove 2 is connected to the main drainage groove 1, and its main function is to divert water in the main drainage groove 1 to the side area of ​​the tire.

[0045] Please see Figure 3 , Figure 3 The diagram shows the combined structure of the diversion groove and the main drainage groove in this invention. Furthermore, the diversion groove 2 is distributed on both sides of the main drainage groove 1 in a strip-like manner, ensuring that water can be evenly diverted to both sides of the tire and eventually reach the tire shoulder. This invention effectively increases the tire's contact area on wet roads and reduces the risk of slippage through the structural design of the diversion groove 2.

[0046] In some embodiments, the pulse-type trench 3 is connected to the diversion trench 2 for regulating and optimizing water flow. A central guide plate 4 is provided in the middle of the pulse-type trench 3.

[0047] Furthermore, the shape of the central deflector 4 can be elliptical, or formed by the intersection of two circular arcs.

[0048] Please see Figure 4 , Figure 4 The diagram shows the combined structure of the pulse-type groove and the central guide plate in this invention. The design of the central guide plate 4 can balance the water flow and optimize the water flow velocity, so that the water flow forms a pulse shape within the pulse-type groove 3, further enhancing the drainage effect. At the same time, it can also enhance the tire's grip and adhesion in wet and complex conditions.

[0049] In some embodiments, the connecting grooves 5 are used to connect the pulsed grooves 3 arranged at different positions along the longitudinal direction of the tire; for example, the shape of these connecting grooves 5 can be lightning-shaped, which can easily break through the water film and accelerate drainage on both sides, further improving the tire's grip performance on wet roads.

[0050] In some embodiments, the water outlet 6 is located at the end of the pulse groove 3 and at the tire shoulder. The opening of the water outlet 6 expands outward, and the structural design of the water outlet 6 can improve drainage efficiency and ensure that water can be quickly discharged to the outside of the tire.

[0051] In other embodiments, a tire is also provided, the tire tread having the above-described tire pattern.

[0052] In summary, the tire tread pattern and tire of this invention, through a unique structural design, achieve a balance between drainage and grip performance. The synergistic effect of the main drainage groove 1, the diversion groove 2, the pulse groove 3, the central guide plate 4, the connecting groove 5, and the water outlet 6 allows the tire to quickly expel water from wet roads, maintaining effective contact area with the ground, thereby improving driving safety and handling stability. Simultaneously, this tire tread pattern design also reduces tire noise during driving, enhancing driving comfort.

[0053] 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.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
