[0001] This utility model relates to the field of automotive parts technology, and in particular to a tire tread pattern structure. Background Technology
[0002] In recent years, all-terrain SUVs have become increasingly popular among consumers in the Chinese market, with their market share steadily rising. All-terrain SUV tires are typically used on complex road surfaces, such as mountains, mud, and sand. The tires come into contact with a large amount of mud, sand, and gravel. Currently, the tires used in the market generally have poor mud and sand removal performance and cannot adapt to complex road surfaces, resulting in low passability.
[0003] Therefore, there is a need to provide a tire tread pattern structure to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a tire tread pattern structure that makes it easier to throw off mud, sand and stones, enhances tire grip, and ensures driving safety and stability.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A tire tread pattern structure includes a tire tread and a component disposed on the tire tread:
[0007] The tread pattern mechanism includes a first pattern group and a second pattern group. Multiple first pattern groups and multiple second pattern groups are spaced apart and alternately arranged along the circumference of the tire tread. The sidewalls of the first pattern group and the second pattern group are inclined to the tire tread. The sidewalls of adjacent first pattern groups, the sidewalls of the second pattern groups, and the tire tread form a first pattern groove.
[0008] Preferably, the extension direction of the first tread pattern group and the extension direction of the second tread pattern group are both set at an angle to the axial direction of the tire tread.
[0009] Preferably, the first pattern group includes a first pattern block and two second pattern blocks spaced apart, with the two second pattern blocks located on both sides of the first pattern block, and both the first pattern block and the second pattern block having an inclined chamfer.
[0010] Preferably, both the first patterned block and the second patterned block have a first groove.
[0011] Preferably, the second pattern group includes two third pattern blocks and a first reinforcing rib, with the two third pattern blocks connected to the first reinforcing rib.
[0012] Preferably, the third patterned block has a second groove.
[0013] Preferably, the tire tread pattern structure further includes:
[0014] Two shoulder tread groups are disposed on both sides of the tire tread, and a second tread groove is formed between the two shoulder tread groups and the tread tread mechanism; the shoulder tread group includes a plurality of fourth tread blocks and a plurality of second reinforcing ribs, the plurality of fourth tread blocks are circumferentially spaced around the tire tread, and two adjacent fourth tread blocks are connected by the second reinforcing ribs.
[0015] Preferably, the adjacent fourth patterned blocks are staggered.
[0016] Preferably, the fourth patterned block has a third groove.
[0017] Preferably, the fourth tread block extends to the side of the tire to form a side tread portion, the side tread portion having grooves and / or protrusions and / or patterns.
[0018] The beneficial effects of this utility model are:
[0019] The tire tread pattern structure includes the tire tread and the tread pattern structure disposed on the tire tread. The tread pattern structure includes a first pattern group and a second pattern group. Multiple first pattern groups and multiple second pattern groups are arranged alternately and at intervals along the circumference of the tire tread. The sidewalls of the first pattern group and the second pattern group are both inclined to the tire tread. The sidewalls of adjacent first pattern groups, the sidewalls of second pattern groups, and the tire tread form a first pattern groove.
[0020] Because the first and second tread patterns are spaced apart and alternately arranged along the circumference of the tire tread, and the sidewalls of both the first and second tread patterns are inclined to the tire tread, they can more effectively cut, squeeze, and expel mud, sand, and stones encountered by the tire on complex road surfaces, such as mountains, mud, and sand. The inclined sidewalls make it easier for mud, sand, and stones to be thrown out, reducing the amount of material adhering to the tire and thus enhancing the tire's grip and improving its passability. The alternating first and second tread patterns can increase the contact area between the tire and the ground to a certain extent, especially on dry or hard roads, providing better grip and ensuring driving safety and stability.

[0029] 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.

[0033] In recent years, all-terrain SUVs have become increasingly popular among consumers in the Chinese market, with their market share steadily rising. All-terrain SUV tires are typically used on complex road surfaces, such as mountains, mud, and sand. The tires come into contact with a large amount of mud, sand, and gravel. Currently, the tires used in the market generally have poor mud and sand removal performance and cannot adapt to complex road surfaces, resulting in low passability.
[0034] To solve the above problems, such as Figure 1 As shown, this embodiment provides a tire tread pattern structure, which includes a tire tread and a tread pattern structure disposed on the tire tread. The tread pattern structure includes a first pattern group 1 and a second pattern group 2. Multiple first pattern groups 1 and multiple second pattern groups 2 are spaced apart and alternately disposed along the circumference of the tire tread. The sidewalls of the first pattern group 1 and the second pattern group 2 are both inclined to the tire tread. The sidewalls of adjacent first pattern groups 1 and second pattern groups 2 and the tire tread form a first pattern groove 3.
[0035] Because the first tread pattern group 1 and the second tread pattern group 2 are spaced apart and alternately arranged along the circumference of the tire tread, and the sidewalls of the first tread pattern group 1 and the second tread pattern group 2 are inclined to the tire tread, they can more effectively cut, squeeze and expel mud, sand and stones encountered by the tire on complex road surfaces, such as mountains, mud, and sand. The inclined sidewalls make it easier for mud, sand and stones to be thrown out, reducing the adhesion between the tire and the ground, thereby enhancing the tire's grip and improving the tire's passability. The alternating first tread pattern group 1 and the second tread pattern group 2 can increase the contact area between the tire and the ground to a certain extent, especially on dry or hard roads, providing better grip and ensuring driving safety and stability.
[0036] In this embodiment, the sidewall of the first tread pattern group 1 forming the first tread groove 3 is parallel to the sidewall of the second tread pattern group 2, so that the shape of the first tread groove 3 is more regular, which is conducive to the rapid discharge of mud, sand, stones, etc., and ensures good contact between the tire and the ground, thereby improving grip and handling performance.
[0037] Specifically, the extension direction of the first tread pattern group 1 and the extension direction of the second tread pattern group 2 are both set at an angle to the axial direction of the tire tread. In this case, if... Figure 1As shown, the first tread pattern group 1 and the second tread pattern group 2 are respectively set at an angle to the X-axis direction, which can effectively stagger the contact time of each part of the first tread pattern group 1 and the second tread pattern group 2 with the road surface, reducing noise during driving; and increasing the length of the first tread groove 3 between adjacent first tread pattern group 1 and second tread pattern group 2, thereby improving the tire's ability to drain water, expel mud and sand, expel stones and self-clean.
[0038] Specifically, such as Figure 1 As shown, the first tread pattern group 1 includes a first tread block 11 and two second tread blocks 12 spaced apart. The two second tread blocks 12 are located on both sides of the first tread block 11. Both the first tread block 11 and the two second tread blocks 12 have an inclined chamfer 13. The first tread block 11 and the two second tread blocks 12 are spaced apart to allow mud, sand, stones, etc. to be quickly discharged, ensuring that the tire has good passability on muddy and gravelly roads. The inclined chamfer 13 design allows the first tread block 11 and the second tread block 12 to have an embedding effect on muddy roads, greatly increasing the contact area between the tire tread and the road surface when driving on complex road surfaces such as mountains, mud, and sand, giving the tire better grip and helping the tire's handling and passability on complex road surfaces. In addition, the inclined chamfer 13 design can disperse the stress at the corners of the first tread block 11 and the second tread block 12, enhancing the strength of the first tread block 11 and the second tread block 12.
[0039] In this embodiment, as Figure 1 As shown, the first tread block 11 is S-shaped, and the second tread block 12 is reef-shaped. The two reef-shaped second tread blocks 12 are centrally symmetrically arranged with the S-shaped first tread block 11. The S-shaped first tread block 11 allows the tire to better conform to the road surface during driving, especially when cornering, providing stronger grip and traction, thereby improving handling performance. The S-shaped first tread block 11 can also effectively disperse the heat generated by the tire during driving, improving tire durability. The reef-shaped second tread block 12 increases the contact area between the tire and the ground, improving tire grip and stability. Under complex road conditions, the reef-shaped second tread block 12 can better adapt to changes in the road surface, reducing tire slippage and sideslip.
[0040] Specifically, such as Figure 1 As shown, both the first tread block 11 and the second tread block 12 have first grooves 41. The first grooves 41 are used to distribute the overall stress of the first tread block 11 and the second tread block 12, preventing stress concentration that could lead to cracking; and on wet muddy roads, they can absorb more water, preventing tire slippage and increasing driving comfort. Specifically, the depth of the first grooves 41 ranges from 1mm to 10mm, with the specific value determined by actual needs.
[0041] Specifically, such as Figure 1 As shown, the second tread pattern group 2 includes two third tread blocks 21 and a first reinforcing rib 22, with the two third tread blocks 21 connected by the first reinforcing rib 22. The first reinforcing rib 22 enables the two third tread blocks 21 to support each other during deformation, reducing excessive deformation and thus enhancing the tensile and tear resistance of the two third tread blocks 21, thereby ensuring the tire's grip on complex road surfaces.
[0042] In this embodiment, as Figure 1 As shown, the third tread block 21 is boot-shaped, and the two boot-shaped third tread blocks 21 are centrally symmetrically arranged. The two boot-shaped third tread blocks 21 are connected by a first reinforcing rib 22. The boot-shaped third tread block 21 helps to increase the contact area between the tire and the ground, thereby improving the tire's wear resistance and grip. The boot-shaped third tread block 21 can increase the tire's anti-skid ability during cornering or emergency avoidance. The centrally symmetrical layout and the setting of the first reinforcing rib 22 enable the third tread block 21 to better maintain its shape and position when subjected to lateral forces, reducing the risk of skidding.
[0043] Specifically, such as Figure 1 As shown, a second groove 42 is formed on the third tread block 21. The second groove 42 is used to disperse the overall stress of the third tread block 21, preventing stress concentration from causing cracking; and it can absorb more water on wet muddy roads, preventing tire slippage and increasing driving comfort. Specifically, the depth of the second groove 42 ranges from 1mm to 10mm, with the specific value depending on actual needs.
[0044] In this embodiment, the pitches between adjacent first tread blocks 11, second tread blocks 12, and third tread blocks 21 are not identical, with pitch values ranging from 3 to 5, between 25mm and 75mm. This effectively reduces tire noise during driving and improves tire grip on complex road surfaces, thus benefiting tire handling stability and wear resistance. In practical implementation, finite element simulation technology can be used to optimize the pitch values.
[0045] Specifically, such as Figure 1 As shown, the tire tread pattern structure also includes two shoulder pattern groups 5, which are disposed on both sides of the tire tread, and a second pattern groove 6 is formed between the two shoulder pattern groups 5 and the tread pattern mechanism; the shoulder pattern group 5 includes multiple fourth pattern blocks 51 and multiple second reinforcing ribs 52, the multiple fourth pattern blocks 51 are arranged circumferentially around the tire tread, and two adjacent fourth pattern blocks 51 are connected by a second reinforcing rib 52.
[0046] The shoulder tread pattern 5 helps increase tire grip during cornering, improving vehicle handling. When the vehicle is cornering, the shoulder tread pattern 5 provides better lateral support, reducing the risk of tire skidding. Multiple fourth tread blocks 51 are spaced circumferentially around the tire tread, and the second reinforcing ribs 52 between adjacent fourth tread blocks 51 together form a stable support structure, enabling the tire to have strong handling and grip performance on complex road conditions such as mountains, mud, and sand. At the same time, it can block the direction of airflow during driving, reducing tire noise. The second tread grooves 6 help to remove mud, sand, and stones, significantly improving the tire's self-cleaning power and driving force on muddy and gravel roads, reducing tire noise and wet slip, providing good passability, and improving driving safety.
[0047] In this embodiment, as Figure 1 As shown, the fourth tread block 51 is in the shape of a horseshoe. The horseshoe-shaped fourth tread block 51 has a larger contact area, which can more effectively grip the ground and provide stronger grip and traction, effectively improving the vehicle's starting, acceleration and climbing performance; the horseshoe-shaped fourth tread block 51 can provide stable support and reduce tire sideslip and slippage, which helps to improve the vehicle's handling stability.
[0048] Specifically, such as Figure 1 As shown, two adjacent fourth tread blocks 51 are staggered. The staggered fourth tread blocks 51 can change the relative phase of the sound time domain waves emitted by the left and right tread patterns on the tire tread. When the sound pressure waves of different phases emitted by the left and right tread patterns meet, they will cancel each other out as much as possible, thereby reducing tire noise. The staggered fourth tread blocks 51 can improve water drainage and mud removal performance, and provide improved grip of the shoulder tread group 5 on complex road surfaces.
[0049] Specifically, such as Figure 1 As shown, a third groove 43 is formed on the fourth tread block 51. The third groove 43 is used to disperse the overall stress of the fourth tread block 51, preventing stress concentration from causing cracking; and it can absorb more water on wet muddy roads, preventing tire slippage and increasing driving comfort. Specifically, the depth of the third groove 43 ranges from 1mm to 10mm, with the specific value depending on actual needs.
[0050] Specifically, such as Figure 1As shown, the fourth tread block 51 extends to the tire sidewall to form a sidewall tread portion 511. The sidewall tread portion 511 has grooves 5111 and / or protrusions 5112 and / or tread patterns 5113. The sidewall tread portion 511 has a certain thickness, which can protect the tire sidewall from damage from curbs, stones, and debris, thus protecting the tire sidewall. The grooves 5111 in the sidewall tread portion 511 help to form drainage channels on the tire sidewall, reducing hydroplaning and improving driving safety. The protrusions 5112 in the sidewall tread portion 511 can improve tire grip and vehicle handling stability when the tire sideslips or makes an emergency turn. The tread patterns 5113 in the sidewall tread portion 511 can enhance the tire's visual effect and improve its aesthetics. In this embodiment, the tread pattern 5113 is mountain-shaped, which can indicate the tire's operating environment conditions. At the same time, the addition of knurled lines further enhances the aesthetics.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
