Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tires, in particular to a low-noise interlocking tire. BACKGROUND

[0002] With the development of economy, people have higher requirements for tires, not only paying attention to the wear resistance, load resistance, drainage, comfort and safety of tires, but also increasingly demanding the noise performance of tires.

[0003] The noise of the tire mainly comes from the impact noise generated when the tire pattern block hits the ground. When the tire rolls forward, each individual pattern block is constantly hitting the ground. Due to the deformation of the contact surface, the pattern block always has a movement speed pointing to the center of the tire, and the reason for generating this movement speed is the impact force of the ground on the pattern block, thereby generating impact noise. If the pattern block is regular and continuous, the sound pressure amplitude is equal and the phase is close, and the sound energy after superposition will produce greater pattern impact noise. On the other hand, tire noise also comes from the high-speed flow of air in the longitudinal groove of the tire during tire rotation.

[0004] Tire noise continues during driving, and the intensity of tire noise increases with the increase of vehicle speed. Under the influence of tire noise for a long time, many people will have car sickness symptoms such as dizziness, vomiting, irritability, suffocation, and shortness of breath. Long-term noise interference has other potential hazards to the body. SUMMARY

DETAILED DESCRIPTION

[0029] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

[0031] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "provided with", "connection" and the like should be understood in a broad sense, for example, "connection" can be fixed connection, can also be detachable connection, or integral connection; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication inside two elements. For a person of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0032] As described in the background, the noise of the tire mainly comes from the impact noise generated when the tire pattern block hits the ground. When the tire is rolling forward, each individual pattern block is constantly hitting the ground, and due to the deformation of the contact surface, the pattern block always has a movement speed pointing to the center of the tire, and the reason for generating this movement speed is the impact force of the ground on the pattern block, thereby generating impact noise. If the pattern block is regular and continuous, the equal sound pressure amplitude and the close phase will produce greater pattern impact noise after the superposition of sound energy; on the other hand, tire noise also comes from the high-speed flow of air in the longitudinal groove of the tire during tire rotation. Tire noise continues during driving, and as the vehicle speed increases, the intensity of tire noise also increases. Many people will have car sickness symptoms, such as dizziness, vomiting, irritability, stuffy, and difficulty breathing, under the influence of tire noise for a long time, and there are other potential hazards to the body.

[0033] To improve the above problems, the present application provides a quasi-interlocking low-noise tire, which mainly comprises a tire body and a tread pattern block, wherein, with reference to Figure 1, the tread blocks are arranged in the circumferential direction of the tire body, and the tread blocks include a center block 1, two side blocks 2, and two shoulder blocks 3. The center block 1 is arranged at the middle of the tire body, the two side blocks 2 are arranged on the two sides of the center block 1, and the two shoulder blocks 3 are arranged on the sides of the two side blocks 2 away from the center block 1.

[0034] Further, a first longitudinal groove 4 is formed between the center block 1 and the two side blocks 2, and two second longitudinal grooves 5 are formed between the two side blocks 2 and the two shoulder blocks 3.

[0035] Further, a third longitudinal groove 6 is formed in the middle of each of the two side blocks 2 and arranged in the circumferential direction of the tire body.

[0036] Specifically, in the exemplary embodiment, with reference to Figure 1 and Figure 2 , the center block 1 is integrally connected with a plurality of first protrusions 11 on the two sides of the two side blocks 2, and a first concave portion 12 is formed between adjacent two first protrusions 11. The first protrusions 11 can change the relatively regular and continuous pattern structure of the original center block 1 into an irregular and discontinuous pattern structure, so as to avoid the superposition of sound energy and reduce the impact noise of the tread pattern.

[0037] Further, with reference to Figure 2 and Figure 3 , the center block 1 includes a plurality of interlocking units connected in sequence in the circumferential direction of the tire body. The interlocking units include a first interlocking block 13 and a second interlocking block 14, so as to refine the center block 1 and enhance the vibration reduction and noise reduction performance and the grip performance of the tread.

[0038] Further, a plurality of fourth protrusions 131 and fourth concave portions 132 are formed on the inner side of the first interlocking block 13, and a plurality of fifth protrusions 141 and fifth concave portions 142 are formed on the inner side of the second interlocking block 14. The fifth protrusions 141 are embedded in the fourth concave portions 132, and the fourth protrusions 131 are embedded in the fifth concave portions 142, so as to further refine the center block 1 and further enhance the vibration reduction and noise reduction performance and the grip performance of the tread.

[0039] Specifically, with reference to Figure 4In the exemplary embodiment, the two sides of the side pattern block 2 are integrally connected with a plurality of second protrusions 21, and a second inner recess 22 is formed between any two adjacent second protrusions 21. The second protrusion 21 can change the relatively regular and continuous pattern structure of the original side pattern block 2 into an irregular and discontinuous pattern structure, so as to avoid the superposition of sound energy, thereby reducing the impact noise of the tread pattern; secondly, the second protrusion 21 and the second inner recess 22 make the first longitudinal groove 4 and the second longitudinal groove 5 on the tread form a zigzag path, that is, the high-speed flow of air in the longitudinal groove of the tread during the rotation of the tire is slowed down, thereby further reducing the tire noise.

[0040] Further, referring to Figure 1 , a plurality of second protrusions 21 close to the center pattern block 1 are arranged opposite to a plurality of first inner recesses 12, and a plurality of first protrusions 11 are arranged opposite to a plurality of second inner recesses 22. During the driving of the vehicle, the tread pattern is deformed under pressure, the first protrusion 11 can be embedded in the second inner recess 22 close to the center pattern block 1, and the second protrusion 21 close to the center pattern block 1 can be embedded in the first inner recess 12, that is, the center pattern block 1 and the side pattern block 2 can be interlocked, thereby improving the vibration avoidance performance of the tire, that is, reducing the tire noise generated by the vibration of the tire.

[0041] Further, referring to Figure 1 and Figure 4 , a plurality of first transverse grooves 7 and a plurality of second transverse grooves 8 are further provided on the side pattern block 2, the first transverse groove 7 communicates the second longitudinal groove 5 and the third longitudinal groove 6, and the second transverse groove 8 communicates the first longitudinal groove 4 and the third longitudinal groove 6, that is, the first transverse groove 7 and the plurality of second transverse grooves 8 are arranged to communicate the first longitudinal groove 4 and the second longitudinal groove 5, so that the tread can drain water and mud in time, and the self-cleaning function of the tire is enhanced.

[0042] Further, referring to Figure 4 , the first transverse groove 7 and the second transverse groove 8 are both arranged obliquely relative to the third longitudinal groove 6, which not only can drain the mud or water along the obliquely arranged first transverse groove 7 and second transverse groove 8 during the rotation of the tire, but also can drain the high-speed flowing air in the third longitudinal groove 6 along the obliquely arranged first transverse groove 7 and second transverse groove 8, thereby avoiding the continuous high-speed flow of air in the third longitudinal groove 6, thereby improving the noise reduction performance.

[0043] Further, referring to Figure 4, the middle part of the side block 2 is also provided with a plurality of transverse inner grooves 23, the plurality of transverse inner grooves 23 are communicated with the third longitudinal groove 6, and are arranged at the same inclined angle towards the first transverse groove 7 and / or the second transverse groove 8, so that the third longitudinal groove 6 forms a zigzag path, that is, the high-speed flow of air in the third longitudinal groove 6 of the tire during rotation is slowed down, thereby further reducing the tire noise.

[0044] Specifically, in the exemplary embodiment, with reference to Figure 1 and Figure 5 , the two sides of the shoulder block 3 are integrally connected with a plurality of third protrusions 32, and a third inner recess 33 is formed between adjacent two third protrusions 32. The third protrusion 32 can change the relatively regular and continuous pattern structure of the original shoulder block 3 into an irregular and discontinuous pattern structure to avoid sound energy superposition, thereby reducing the impact noise of the tire pattern; secondly, the third protrusion 32 and the third inner recess 33 make the second longitudinal groove 5 on the tire form a zigzag path, that is, the high-speed flow of air in the longitudinal groove of the tire during rotation is slowed down, thereby further reducing the tire noise.

[0045] Further, the plurality of third protrusions 32 are oppositely arranged with the plurality of second inner recesses 22 close to the shoulder block 3, and the plurality of second protrusions 21 are oppositely arranged with the plurality of third inner recesses 33. During vehicle driving, the tire pattern is deformed by extrusion, the third protrusion 32 can be embedded into the second inner recess 22 close to the shoulder block 3, the second protrusion 21 close to the shoulder block 3 can be embedded into the third inner recess 33, that is, the shoulder block 3 and the side block 2 can be engaged and interlocked, thereby improving the vibration avoidance performance of the tire, that is, reducing the tire noise generated by tire vibration.

[0046] Further, with reference to Figure 5 , the shoulder block 3 includes a plurality of shoulder blocks 31, the plurality of shoulder blocks 31 correspond one-to-one with the plurality of third protrusions 32 and are integrally connected, which can further refine the shoulder block 3, thereby enhancing the vibration reduction and noise reduction performance and the grip performance of the tire. The plurality of shoulder blocks 31 are arranged along the circumference of the tire body, and a third transverse groove 9 is formed between adjacent two shoulder blocks 31, so that the tire can drain water and mud in time, thereby enhancing the self-cleaning function of the tire.

[0047] Further, with reference to Figure 1 and Figure 5 , the third transverse groove 9 is arranged obliquely relative to the third longitudinal groove 6, which not only can drain the mud or water along the obliquely arranged third transverse groove 9 during tire rotation, but also can drain the air flowing in the second longitudinal groove 5 along the obliquely arranged third transverse groove 9, thereby avoiding the continuous high-speed flow of air in the second longitudinal groove 5, thereby improving the noise reduction performance.

[0048] Further, referring to Figure 1 , the inclination direction of the third transverse groove 9 is arranged opposite to the inclination direction of the first transverse groove 7 and the second transverse groove 8, which can avoid the air flowing out of the first transverse groove 7 and the second transverse groove 8 to continue flowing into the third transverse groove 9, i.e. shorten the transverse flow path of the air in the tread pattern block, thereby further reducing the noise generated by the air flowing in the tread groove.

[0049] In summary, first, by arranging the first protruding part 11, the second protruding part 21 and the third protruding part 32, the original regular and continuous pattern structure of the center pattern block 1, the side pattern block 2 and the shoulder pattern block 3 can be changed into irregular and discontinuous pattern structure, so as to avoid sound energy superposition, thereby reducing the impact noise of the tread pattern; secondly, the first protruding part 11, the second protruding part 21 and the third protruding part 32, the first concave part 12, the second concave part 22 and the third concave part 33 make the tread longitudinal groove form a zigzag path, i.e. slow down the high-speed flow of air in the tread longitudinal groove during tire rotation, thereby further reducing the tire noise; in addition, during the driving of the vehicle, the tread pattern is deformed under pressure, the first protruding part 11, the second protruding part 21 and the third protruding part 32 can be embedded in the first concave part 12, the second concave part 22 and the third concave part 33, i.e. the center pattern block 1, the side pattern block 2 and the shoulder pattern block 3 can be interlocked, thereby improving the vibration avoidance performance of the tire, i.e. reducing the tire noise generated by tire vibration.

[0050] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can be modified to the technical solutions recorded in the foregoing embodiments, or equivalent replacement of part of the technical features.
