Description

Technical Field

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

[0002] Urban SUVs, as an important means of transportation in society, combine the comfort of a sedan with the spaciousness and functionality of a station wagon, while also possessing a certain degree of off-road capability. They can meet the needs of various scenarios such as family use and business travel, and their market share has been steadily increasing. If a car is driven primarily on paved city roads and highways, it is necessary to choose specialized tires suitable for these road conditions. In addition to basic load-bearing capacity and high-speed safety, these tires must also ensure higher fuel efficiency to guarantee the vehicle's range, as well as low noise levels during driving to improve passenger comfort.

[0003] Existing tires typically lack fuel efficiency and have limited ability to absorb road impacts, potentially generating significant noise during driving and reducing ride comfort. Therefore, to achieve both good high-speed performance and fuel-efficient range while minimizing tire noise on highways, precise tire modifications are needed, designing tire tread patterns that meet the specific requirements of urban SUVs and new energy vehicles.

[0007] The tire tread has four main grooves that extend circumferentially along the tire tread and are spaced parallel to each other along the width of the tire. The four main grooves divide the tire tread into a central tread area, two side tread areas, and two shoulder areas. The side tread areas are located on both sides of the central tread area, and the shoulder areas are located on the side of the side tread area away from the central tread area.

[0008] The tire tread has multiple treads arranged in a centrally symmetrical manner. All treads are connected to the main grooves and extend at an angle to the width direction of the tire.

[0009] At least one of the main trenches is provided with an arc-shaped groove, and both ends of the arc-shaped groove are connected to the same main trench.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0028] Reference Figure 1 This embodiment proposes a tire and a vehicle, with the aforementioned tire installed on the vehicle. The tire includes a tread with four main grooves 1. The main grooves 1 extend circumferentially along the tread and are spaced parallel to each other along the width of the tire. The four main grooves 1 divide the tread into five regions: a central tread region 2, two side tread regions 3, and two shoulder regions 4. The side tread regions 3 are located on both sides of the central tread region 2, and the shoulder regions 4 are located on the side of the side tread regions 3 away from the central tread region 2. That is, the five regions along the width of the tire are, in order, shoulder region 4 - side tread region 3 - central tread region 2 - side tread region 3 - shoulder region 4. Preferably, the width of the central tread region 2 ranges from 5mm to 20mm.

[0029] The tire tread features multiple centrally symmetrical tread lines, resulting in a more even contact area with the ground during driving. This distributes stress across the tread surface, preventing deformation and reducing the probability of heat generation and energy loss, thereby lowering the rolling resistance coefficient and reducing energy consumption during vehicle operation, thus improving driving range. Furthermore, the centrally symmetrical tread pattern eliminates the need to distinguish between the inner and outer sides of the tire, allowing for direct alignment during installation, improving efficiency, reducing the risk of installation errors, and simplifying maintenance. Additionally, the centrally symmetrical tread pattern allows the tire to rotate in multiple directions without a specific orientation, enabling better distribution and absorption of impacts and pressures from all directions during driving. This results in more even tire wear, reducing the possibility of excessive wear in certain areas and extending tire lifespan.

[0030] Furthermore, the multiple grooves are all connected to the main groove 1 and extend at an angle to the width of the tire, meaning the multiple grooves are angled to improve the tire's grip. Especially when the vehicle is driving on flooded areas, the tire tread comes into contact with the water on the ground, and the water can be squeezed into the main groove 1, then enters the angled grooves to form a "propeller effect" and is thrown out of the tread, avoiding the eddy currents caused by vertical impact on the main groove 1. This improves the tire's drainage and grip performance, thereby ensuring the vehicle's handling stability and ride comfort. In this embodiment, the main groove 1 is deeper than the multiple grooves, increasing the water intake capacity of the main groove 1. In addition, the main groove 1 is a trapezoidal groove, with the bottom width being smaller than the top width, increasing the water intake area of ​​the main groove 1 and improving the tire's grip. Side grooves 11 are also provided on both sides of the main groove 1 to increase the tire's aesthetics. Preferably, the distance between multiple stripes ranges from 15mm to 55mm, and the number of stripes ranges from 50 to 100.

[0031] In addition, at least one main groove 1 is provided with an arc-shaped groove 5, both ends of which are connected to the same main groove 1, reducing tire noise during driving. The arc-shaped groove 5 and the connected main groove 1 can form a gas channel. When gas enters the main groove 1, the curvature of the arc-shaped groove 5 can guide the airflow to pass smoothly, avoiding the harsh noise generated by strong direct current gas impact and reducing the noise generated by air turbulence. In addition, when the vehicle is driving on a flooded area, the connection of both ends of the arc-shaped groove 5 to the same main groove 1 can also form a closed-loop drainage channel. When the tire tread comes into contact with the water on the ground, the water is squeezed into the main groove 1 and can flow into the arc-shaped groove 5 from both ends, improving drainage efficiency. In this embodiment, the arc-shaped groove 5 is a semi-circular groove with a radius ranging from 0.5mm to 2.0mm.

[0032] Refer again Figure 1The tread pattern includes a first tread group 6 disposed in the central tread area 2. The first tread group 6 includes a partition groove 61, which includes a first groove segment 611 and a second groove segment 612. The first groove segment 611 and the second groove segment 612 extend at an angle to the width direction of the tire and are spaced apart. The ends of the first groove segment 611 and the second groove segment 612 that are far apart from each other are respectively connected to the main grooves 1 on both sides of the central tread area 2. The central tread area 2 is usually the area where the tire has the most contact with the ground during driving. The partition groove 61 can ensure the rigidity of the central tread area 2 on the tire surface and ensure the tire's load-bearing capacity. Preferably, the groove width of the partition groove 61 is in the range of 0.4mm-2.0mm.

[0033] Furthermore, the first tread pattern group 6 also includes a continuous groove 62. The two ends of the continuous groove 62 are connected to the main grooves 1 on both sides of the central tread area 2. The continuous groove 62 and the partition groove 61 are alternately arranged along the circumference of the tread, and are parallel to each other. The spacing between adjacent continuous grooves 62 and partition grooves 61 is equal. This arrangement improves the load-bearing capacity at the center of the tire, ensures tire handling stability and drainage performance, and is beneficial to the vehicle's handling and ride comfort on paved urban roads. Preferably, the width of the continuous groove 62 ranges from 0.4mm to 2.0mm. In addition, an inclined angle is added to both ends of the continuous groove 62, meaning that the width at both ends of the continuous groove 62 is slightly larger than the width in the middle. This enhances the tire's ground contact drainage capacity and its self-cleaning performance in removing small stones and other fine debris.

[0034] The tire tread also features secondary grooves 9, located in the sidewall tread region 3. These grooves extend circumferentially along the tread surface, dividing the sidewall tread region 3 into a first half-zone 31 and a second half-zone 32. The first half-zone 31 is located on the side of the second half-zone 32 furthest from the central tread region 2. The sidewall tread region 3 plays a crucial role in improving tire rolling resistance, starting / braking / cornering performance. By dividing the sidewall tread region 3 into the first half-zone 31 and the second half-zone 32, the secondary grooves 9 shorten the length of the tread pattern within the sidewall tread region 3 in the tire width direction, reducing tire friction and rolling resistance. Simultaneously, they ensure the sidewall tread region 3 has appropriate rigidity, improving the tread's water absorption and retention capacity on wet surfaces, thus guaranteeing the tire's wet handling performance. Preferably, the width of the secondary grooves 9 ranges from 1.0 mm to 3.0 mm.

[0035] The tread pattern also includes a second tread group 7 disposed in the sidewall tread area 3. Specifically, the second tread group 7 includes a first groove 71 and a second groove 72 disposed in the first half-area 31. Both ends of the first groove 71 and the second groove 72 are connected to the main groove 1 and the secondary groove 9, respectively. The width of the first groove 71 is smaller than the width of the second groove 72. The second groove 72 has a larger width, which can serve as the main drainage path in the sidewall tread area 3, quickly diverting a large amount of accumulated water and preventing slippage caused by the water film effect. The first groove 71 has a smaller width, which can absorb residual water film through capillary effect, increasing the microscopic contact area. The first groove 71 and the second groove 72 work together to further improve the tire's wet grip and dry handling stability. In this embodiment, a second groove 72 is disposed every two first grooves 71.

[0036] In addition, a chamfered notch 74 is provided at one end of the second groove 72, and the chamfered notch 74 is connected to the main groove 1. The chamfered notch 74 is located at the sharp corner where the second groove 72 connects to the main groove 1, which can prevent excessive stress concentration at the sharp corner and thus prevent cracking. This is beneficial to the wear resistance and safety of the tire during driving on paved urban roads. Preferably, the groove width of the chamfered notch 74 is in the range of 1mm-5mm.

[0037] Furthermore, the second tread group 7 also includes a third groove 73, which is located in the second half-region 32. The two ends of the third groove 73 are connected to the secondary groove 9 and the main groove 1, respectively. The groove width of the third groove 73 near the main groove 1 is smaller than the groove width near the secondary groove 9. That is to say, the groove width of the third groove 73 near the center tread region 2 is smaller than the groove width near the shoulder region 4. This gradual change in groove width makes the tread stiffness non-linearly distributed, achieving force balance.

[0038] The tread pattern also includes a third tread group 8 located in the shoulder area 4. This third tread group 8 includes a fourth groove 81 and a fifth groove 82 alternately arranged circumferentially along the tire tread. Both ends of the fourth groove 81 are connected to the main groove 1, and one end of the fifth groove 82 is connected to the main groove 1 while the other end is connected to the outside. The width of the fourth groove 81 is smaller than the width of the fifth groove 82. The shoulder area 4, as the junction of the tire sidewall and the sidewall tread area 3, typically bears significant stress and is prone to accumulating heat and moisture. The fourth groove 81, with both ends connected to the main groove 1, forms a drainage grid in the shoulder area 4, guiding water accumulated on the shoulder into the main groove 1 through a loop path, reducing the amount of residual water film on the shoulder. The fifth groove 82, with one end connected to the main groove 1 and the other end connected to the outside, can quickly drain water from the main groove 1, improving the drainage capacity on both sides of the tire and effectively dispersing the heat generated in the shoulder area 4 during tire operation.

[0039] In addition, the narrower fourth groove 81 increases the contact area between the tire and the ground, improving steering grip when the vehicle turns. The wider fifth groove 82 improves drainage speed. Preferably, the width of the fourth groove 81 ranges from 0.4mm to 2.5mm, and the width of the fifth groove 82 ranges from 1mm to 10mm.

[0040] Furthermore, the tire tread is also provided with side grooves 10 that communicate with the outside and extend circumferentially along the tire tread. The side of the fifth groove 82 away from the main groove 1 is connected to the side grooves 10. When the vehicle is traveling in a straight line, the water accumulated in the main groove 1 can be discharged to the outside through the fifth groove 82 to the side grooves 10, improving the drainage capacity and water absorption performance of the tire shoulder area 4. Moreover, the side grooves 10 are open and not in contact with the ground, which can effectively perform the venting / draining function, ensuring the tire's high-speed performance safety and comfort, while also improving the tire's aesthetics.

[0041] The fifth groove 82 is also provided with a receiving groove 821 at one end near the main groove 1. The groove depth of the receiving groove 821 is shallower than that of the fifth groove 82, so as to serve as a receiving function and prevent excessive airflow / water flow impact from causing noise.
