Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to the attached drawings 1-4 in the specification, the groove tire with the NVH performance improved comprises a tire body 1, two first pattern blocks 2 are arranged on the surface of the tire body 1, two second pattern blocks 3 are arranged between the two first pattern blocks 2, a first groove 4 is formed between one first pattern block 2 and one second pattern block 3, a second groove 5 is formed between the two second pattern blocks 3, a plurality of first middle grooves 6 are obliquely arranged on the surface of the first pattern block 2, a second middle groove 7 is arranged on one side of the first middle groove 6, one of the second pattern blocks 3 is obliquely provided with a first central groove 8 on the surface, the other second pattern block 3 is obliquely provided with a second central groove 9 on the surface, a guide groove 10 is arranged between the two first central grooves 8 and the second central groove 9, and a stone-proof subassembly is arranged inside each of the first middle groove 6 and the second middle groove 7.

As shown in fig. 1 and 2, the first middle grooves 6 and the second middle grooves 7 are symmetrically distributed around the first blocks 2, and the second middle grooves 7 are arranged between the two first middle grooves 6, so that the noise generated by the tire body 1 and the ground is reduced when the tire body 1 rotates.

As shown in fig. 1 and 2, the first central groove 8 and the second central groove 9 are symmetrically distributed around the second groove 5, and the first central groove 8 and the second central groove 9 are both narrower than the width of the guide groove 10, so that the stones can slide into the guide groove 10 from the first central groove 8 and the second central groove 9 due to inertia and fall off due to the narrow width of the first central groove 8 and the second central groove 9.

As shown in fig. 1 and 2, the guide groove 10 is obliquely arranged between the two first central grooves 8 and the second central groove 9, and both ends of the guide groove 10 are communicated with the first central groove 8 and the second central groove 9, so that stones stuck in the first central groove 8 and the second central groove 9 can slide into the guide groove 10.

As shown in fig. 1, 2 and 4, the first middle groove 6 and the second middle groove 7 are not arranged in the same depth as the first central groove 8 and the second central groove 9, the edges of the first middle groove 6 and the second middle groove 7 are arranged in an arc shape, and the cross sections of the first central groove 8 and the second central groove 9 are arranged in a rectangular shape, so that the noise performance of the tire when the vehicle runs can be greatly reduced by arranging the first middle groove 6 and the second middle groove 7 in the same depth as the first central groove 8 and the second central groove 9, the resonance caused by air flow is reduced, and the noise index is reduced.

The real-time scene is specifically as follows: when in use, after the tire is contacted with the ground in the rotation process, according to the depth inconsistency of the first middle groove 6 and the second middle groove 7 with the first central groove 8 and the second central groove 9, the tire can further pass through the first middle groove 6 and the second middle groove 7 with the first central groove 8 and the second central groove 9 with different depths when in operation, the resonance generated by the tire can avoid the first middle groove 6 and the second central groove 9 so as to reduce the noise index, the drum noise of the tire during the vehicle running can be greatly reduced, the NVH performance of the tire can be improved, and when the tire is contacted with the ground, once stones are clamped into the first central groove 8 and the second central groove 9, because the guide groove 10 communicated between the first central groove 8 and the second central groove 9 is arranged, and the width of the guide groove 10 is larger than that of the first central groove 8 and the second central groove 9, the stones can slide into the guide groove 10 due to the inertia of the vehicle running, and finally out of the interior of the guide groove 10.

Prevent stone sub-assembly and include a plurality of fixing bases 11, inside a plurality of fixing bases 11 evenly distributed groove 7 in first well groove 6 and the second, a plurality of fixing bases 11 top all are provided with rubber strip 12, rubber strip 12 top is provided with rubber push pedal 13.

As shown in fig. 3, the cross section of the fixing seat 11 is trapezoidal, two ends of the rubber strip 12 are fixedly connected with the fixing seat 11 and the rubber pushing plate 13, the rubber strip 12, the rubber pushing plate 13 and the fixing seat 11 are made of rubber, and the rubber strip 12 is an elastic member.

As shown in the attached figures 1 and 3, the cross section of the rubber push plate 13 is arc-shaped, and the rubber push plate 13 is structurally matched with the first middle groove 6 and the second middle groove 7, so that the rubber push plate 13 is arranged inside the first middle groove 6 and the second middle groove 7, and stones are prevented from being clamped into the first middle groove 6 and the second middle groove 7 through the arrangement of the rubber push plate 13.

The real-time scene is specifically as follows: in the use, when groove 7 was inside in groove 6 and the second in the first groove of stone card advances, the stone can contact rubber push pedal 13 at first, and then rubber push pedal 13 can drive rubber strip 12 and carry out the bending and make rubber push pedal 13 present the slope form after receiving the oppression of stone, however the tire leaves ground after rotating when, because rubber push pedal 13 does not receive the oppression of stone, make rubber strip 12 return and drive the rubber push pedal 13 return of slope, and then can make the stone pop out.

The utility model discloses use as follows: the utility model discloses when in actual use, at first through degree inconsistent first mesolot 6 and second mesolot 7 and first central groove 8 and second central groove 9, make the setting of the differentiation degree of depth between it reduce the drum of tire and make an uproar, and then the NVH performance of the tire that promotes, nevertheless the stone of card income first central groove 8 and second mesolot 7 groove can make the stone landing to guide way 10 inside because of inertia when the tire moves, and then fall out, and the inside stone of card income first mesolot 6 and second mesolot 7 can make crooked rubber strip 12 return because of setting up of push pedal 14, and then rubber strip 12 through the return makes rubber push pedal 13 release the stone.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
