For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0037] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] refer to Figures 1 to 5 The embodiment of the present application provides a low noise tire, comprising: a tire body 2, wherein the tire body 2 comprises a middle rib 20 extending along the circumference of the tire, and longitudinal grooves 21 are provided on both sides of the middle rib. Figure 6 The depth h5 of the longitudinal groove 21 is 4-7 mm, for example, 4 mm, 4.2 mm, 4.9 mm, 6 mm, 6.5 mm, 7 mm, etc., along the first direction (i.e. Figure 1 D direction as shown), a plurality of shoulder grooves 22 are provided on the outer surface of the tire body 2 near the edge positions on both sides (i.e., the shoulder parts), and the plurality of shoulder grooves 22 are spaced apart along the circumference of the tire, and each shoulder groove 22 is spaced apart from the longitudinal groove 21 along the first direction, that is, the outer surface of the tire body 2 is symmetrically provided with longitudinal grooves 21 near the inner side of the shoulder groove 22.

[0039] For example, reference Figures 3 to 6The longitudinal groove 21 includes a gasket placement area 210 and a first foreign body ejection area 211, along the radial direction of the tire and away from the center point of the tire (i.e. Figure 6 b direction as shown), the first foreign matter ejection area 211 is located above the gasket placement area 210.

[0040] For example, reference Figures 1 to 3 Each shoulder groove 22 includes a pad placement area 220 and a second foreign body ejection area 221, which are arranged along the radial direction of the tire and away from the center point of the tire (i.e. Figure 3 b direction as shown), the second foreign matter ejection area 221 is located above the pad placement area 220.

[0041] For example, reference Figures 1 to 6 A gasket 23 is attached to the gasket placement area 210, and the gasket 23 extends along the circumference of the tire. That is to say, two gaskets 23 extending along the circumference of the tire are embedded in the tire body 2. The gasket 23 is embedded in the tire body 2 by hot melting. Along the circumference of the tire, the outer surface of each gasket 23 is annularly provided with a first foreign matter ejection area 211, and the two gaskets 23 are spaced apart along the first direction.

[0042] For example, reference Figures 1 to 3 The pad 24 is attached to the pad placement area 220, and the pad 24 is attached to the pad placement area 220 by hot melting, that is, along the first direction (i.e. Figure 2 D direction as shown), a plurality of pads 24 are provided on opposite sides of the two washers 23, and the plurality of pads 24 are distributed at intervals along the circumference of the tire. A second foreign body ejection area 221 is provided on the outer surface of each pad 24 along the circumference of the tire.

[0043] For example, reference Figures 1 to 3 Combined with Figure 6 The gasket 23 and the pad 24 serve as protective layers for the tire body 2, and a relatively hard material can be selected. Specifically, the gasket 23 serves as a protective layer for the longitudinal groove 21, and the pad 24 serves as a protective layer for the shoulder groove 22, which can effectively prevent foreign objects from getting stuck in the tire body 2. At the same time, a first foreign object ejection area 211 is arranged above the gasket placement area 210, which can better eject foreign objects in the longitudinal groove 21, and a second foreign object ejection area 221 is arranged above the pad placement area 220, which can better eject foreign objects in the shoulder groove 22. Such a design can prevent foreign objects from getting stuck in the tire body 2 and extend the service life of the tire.

[0044] The embodiments of the present application do not limit the types of foreign matter, such as stones, wood blocks, sand, broken bricks, etc. When the tire body 2 rotates at high speed, when the foreign matter enters the first foreign matter ejection area 211 of the longitudinal groove 21, the foreign matter will not stay here, but will be directly thrown out of the longitudinal groove 21 under the action of centrifugal force. Similarly, when the foreign matter enters the second foreign matter ejection area 221 of the shoulder groove 22, the foreign matter will not stay here, but will be directly thrown out of the shoulder groove 22 under the action of centrifugal force.

[0045] It should be noted that the embodiments of the present application do not limit the number of shoulder grooves 22, the number of block placement areas 220 and the number of blocks 24, as long as the number of block placement areas 220 and the number of shoulder grooves 22 of blocks 24 remain consistent. For example, ten shoulder grooves 22 may be provided, corresponding to ten block placement areas 220 and ten blocks 24, fifteen shoulder grooves 22 may be provided, corresponding to fifteen block placement areas 220 and fifteen blocks 24, or twenty shoulder grooves 22 may be provided, corresponding to twenty block placement areas 220 and twenty blocks 24.

[0046] The specific structures of the gasket placement area 210, the first foreign matter ejection area 211, the cushion block placement area 220 and the second foreign matter ejection area 221 are described in detail below.

[0047] For example, reference Figure 5 and Figure 6 Combined with Figure 2 The depth h3 of the gasket placement area 210 is 3-5 mm, for example, 3 mm, 3.2 mm, 3.5 mm, 5 mm, etc. The gasket placement area 210 includes a first vertical wall 212, a first horizontal bottom wall 213 and a second vertical wall 214 connected in sequence. The first vertical wall 212 and the second vertical wall 214 are both along the circumference of the tire (i.e. Figure 2 The C direction shown in the figure) extends along the first direction (i.e. Figure 2 The first vertical wall 212 extends along the circumference of the tire, and the gasket 23 is respectively attached to the first vertical wall 212, the first horizontal bottom wall 213 and the second vertical wall 214.

[0048] Exemplarily, the gasket 23 is respectively attached to the first vertical wall 212, the first horizontal bottom wall 213 and the second vertical wall 214, so that the gasket 23 is completely placed in the gasket placement area 210, ensuring the tightness between the gasket 23 and the longitudinal groove 21, and ensuring the safety of the tire during driving. That is to say, there is no gap between the gasket 23 and the longitudinal groove 21, so that foreign matter will not be able to enter the longitudinal groove 21 through the gasket 23, preventing foreign matter from entering the tire body 2 through the gasket 23 and getting stuck in the tire body 2, thereby affecting the service life of the tire.

[0049] For example, reference Figure 5 and Figure 6 Combined with Figure 1 The depth h4 of the first foreign body ejection area 211 is the depth of the longitudinal groove 21 (reference Figure 2 ) is 0.4-0.6 times the depth h5 of the first foreign matter ejection area 211, the first inclined wall 215 and the second inclined wall 216, the first inclined wall 215 is connected to the first vertical wall 212, the second inclined wall 216 is connected to the second vertical wall 214, the first inclined wall 215 and the second inclined wall 216 are inclined in opposite directions to the first vertical wall 212 and the second vertical wall 214 respectively, and the inclination angle α3 of the first inclined wall 215 and the second inclined wall 216 is 40° to 60°, for example 40°, 45°, 52°, 60°, etc.

[0050] That is, the first foreign matter ejection area 211 is in a trumpet shape, that is, along the radial direction of the tire and away from the center of the tire (i.e. Figure 6 b direction as shown), the cross-section of the first foreign object ejection zone 211 becomes larger and larger. With such a design, when foreign objects enter the longitudinal groove 21, they can be better ejected. In other words, the foreign objects in the longitudinal groove 21 can be guided to move toward the larger opening position of the longitudinal groove, that is, to a position away from the tire body 2.

[0051] That is to say, a first V-shaped cutout (i.e., a first inclined wall 215 and a second inclined wall 216) is provided on the inner surface of the longitudinal groove 21 near the outer surface of the tire body 2, so that foreign objects such as stones, wood blocks, sand, broken bricks, etc. are not easily stuck inside the longitudinal groove 21.

[0052] For example, reference Figures 1 to 3 The pad placement area 220 includes a third inclined wall 222, a second horizontal bottom wall 223, a fourth inclined wall 224 and a first arc wall 225. The third inclined wall 222 and the fourth inclined wall 224 are arranged opposite to each other along the circumference of the tire. One end of the third inclined wall 222 close to the longitudinal groove 21 is smoothly connected to the other end of the fourth inclined wall 224 close to the longitudinal groove 21 through the first arc wall 225. The second horizontal bottom wall 223 is respectively connected to the third inclined wall 222, the first arc wall 225 and the fourth inclined wall 224.

[0053] For example, reference Figure 7 Combined with Figure 1 and Figure 3 , along the radial direction of the tire (i.e. Figure 1 In the direction a shown in the figure, the projection of the pad placement area 220 is in the shape of a teardrop, that is, the radius of the first arc wall 225 is R1, and the radius of the part where the first arc wall 225 is smoothly connected to one end of the third inclined wall 222 close to the longitudinal groove 21 and one end of the fourth inclined wall 224 close to the longitudinal groove 21 is R2, and R1>R2.

[0054] For example, reference Figure 3 and Figure 4 Combined with Figure 1 The second foreign matter ejection area 221 includes a fifth inclined wall 226 and a sixth inclined wall 227. The fifth inclined wall 226 is connected to the third inclined wall 222, and the sixth inclined wall 227 is connected to the fourth inclined wall 224. The fifth inclined wall 226 and the sixth inclined wall 227 are inclined in the opposite directions of the third inclined wall 222 and the fourth inclined wall 224, respectively. That is, in the radial direction of the tire and away from the center of the tire (i.e. Figure 3 b direction as shown), the cross-section of the second foreign body ejection area 221 becomes larger and larger. With such a design, when foreign bodies enter the tread shoulder groove 22, they can be ejected better.

[0055] Specifically, the inclination angle α2 of the third inclined wall 222 and the fourth inclined wall 224 is 60° to 80°, for example, 60°, 67°, 70°, 78°, 80°, etc., the inclination angle α1 of the fifth inclined wall 226 and the sixth inclined wall 227 is 20° to 30°, for example, 20°, 23°, 25°, 30°, etc., the depth h2 of the pad placement area 220 is 3-5mm, for example, 3mm, 3.6mm, 4.2mm, 5mm, etc., the depth h1 of the second foreign object ejection area 221 is 6-8mm, for example, 6mm, 7.2mm, 7.6mm, 8mm, etc., the depth h1 of the second foreign object ejection area 221 is greater than the depth h2 of the pad placement area 220, and the length L of the shoulder groove 22 is 15% to 20% of the tire tread width L1

[0056] That is to say, a second V-shaped cutout (i.e., the fifth inclined wall 226 and the sixth inclined wall 227) is provided on the inner surface of the shoulder groove 22 near the outer surface of the tire body 2, so that foreign objects such as stones, wood blocks, sand, broken bricks, etc. are not easily stuck inside the shoulder groove 22.

[0057] For example, reference Figure 2 and Figure 3 The second foreign matter ejection area 221 also includes a second arc wall 228 , and one end of the fifth inclined wall 226 close to the longitudinal groove 21 and one end of the sixth inclined wall 227 close to the longitudinal groove 21 are smoothly connected through the second arc wall 228 .

[0058] For example, reference Figure 8 Combined with Figure 1 and Figure 2Along the radial direction of the tire, the projection of the second foreign object ejection area 221 is in the shape of a water drop, that is, the radius of the second arc wall 228 is R3, and the radius of the part where the second arc wall 228 is smoothly connected with one end of the fifth inclined wall 226 close to the longitudinal groove 21 and one end of the sixth inclined wall 227 close to the longitudinal groove 21 is R4, R3>R4, and the larger opening position is located on the outside of the tire body 2. With such a design, when the tire body 2 rotates at a high speed, foreign objects in the shoulder groove 22 can be ejected, thereby preventing foreign objects from damaging the tire body 2 and avoiding foreign objects (such as stones) stuck in the tire body during the driving of the car to generate tire noise, effectively reducing tire noise and extending the service life of the tire.

[0059] In general, when the tire body 2 rotates, if a foreign object (such as a stone) enters the shoulder groove 22, the second V-shaped cutout prevents the foreign object from getting stuck in the shoulder groove 22. The teardrop-shaped shoulder groove 22 can guide the foreign object in the shoulder groove 22 to move toward the larger opening of the shoulder groove 22, thereby guiding the foreign object to move out of the shoulder groove 22. The pad 24 at the bottom of the shoulder groove 22 can prevent the foreign object from entering the shoulder groove 22 and the bottom of the shoulder groove 22 from being blocked by the tire body 2. Compression contact, since the material of the pad 24 is harder, foreign objects will not penetrate into the pad 24, thereby preventing foreign objects from entering the shoulder groove 22 and then piercing the bottom of the shoulder groove 22. When the longitudinal groove 21 presses the foreign object, through the setting of the first V-shaped incision, the outer incision of the longitudinal groove 21 is larger, and it is not easy to get stuck with the foreign object. When the foreign object penetrates into the bottom of the longitudinal groove 21, the gasket 23 is made of the same material as the pad 24, and has a similar use principle to the pad 24. The bottom of the longitudinal groove 21 is not easy to penetrate with foreign objects to generate tire noise and affect the service life of the tire.

[0060] For example, reference Figure 1 The tire body 2 is arranged along the circumference of the tire (i.e. Figure 1 The wheel is formed around the hub 1 along the radial direction of the tire, and sound insulation cotton 10 is embedded on the inner side of the hub 1. The setting of the sound insulation cotton 10 can play a buffering role when the tire body 2 contacts the ground, reduce the noise generated when the tire body 2 rotates and contacts the ground, and play a role in reducing tire noise.

[0061] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions.
