[0003] For existing tires, the contact area with the ground is large during tire driving, so noise will be generated with the ground, and the tire noise is large. Moreover, the belt layer is a rubber layer with a neat surface, resulting in a small compression deformation with the inner layer of the tread, leading to a small braking force. Summary of the Utility Model

[0004] Based on the above description, the utility model provides an automobile tire to solve the disadvantages of existing automobile tires, that is, during driving, there is not only a lack of noise reduction structure but also a small braking force.

[0009] Further, an elastic support member is further provided inside the cavity. The elastic support member is set as a sponge block and a plurality of return springs are embedded inside. The top and bottom of each return spring are respectively in close contact with the inner top surface and inner bottom surface of the cavity.

[0010] Further, there are a plurality of the protrusions, which are cylindrical rubber blocks and are uniformly arranged in an array along the circumferential direction on the outer side surface of the belt layer.

[0014] 1. Based on the improvement of the existing tire structure, the present application adopts multiple internal and external sound absorption and noise reduction structures to cooperate with each other, which can effectively absorb the noise generated when the wheel rubs against the road surface, and can also enhance the braking force of the wheel through the protruding portion structure of the belt layer, thereby improving the overall performance of the wheel.

[0022] In order to facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art belonging to the technical field of the present application. The terms used in the specification of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0024] Combined with Figure 1-6 As shown in the figure, an automobile tire includes a carcass 1, a tread 2, and a belt layer 3 disposed in the middle. Among them, on the tread 2, through a plurality of vertically arranged anti-slip grooves 21, the surface of the tread 2 is separated to form a central tread block 22 and a shoulder tread block 23, and the central tread block 22 and the shoulder tread block 23 are separated into several small blocks of the same size by pitch, and an arc-shaped shallow groove is arranged at the center of the surface of each small block.

[0025] In the above structure, the central tread block 22 has a straight pitch, while the shoulder tread block 23 has an arc-shaped pitch, and the width and depth of the straight pitch and the arc-shaped pitch are the same, and both are interconnected with the anti-slip groove 21, thus forming an asymmetric structure. This structure is mainly used to discharge the water attached to the tire on rainy days or during driving, preventing the appearance of a water film on the wheel surface.

[0026] However, during actual driving, when the surface of the tire rubs against the road surface, noise will be generated. Therefore, in order to reduce this noise, a cavity 24 should be provided inside each small block of the central tread block 22 and the shoulder tread block 23. The cavity can be set as a rectangular structure, and through holes are respectively arranged on both sides of it, making it interconnected with the anti-slip grooves 21 on both sides, so that the noise generated during driving will be transmitted along the anti-slip groove 21 to the through holes and finally enter the cavity 24.

[0027] An elastic support member is further provided inside the cavity 24. The elastic support member is made of a sponge block and a return spring. The sponge block fills the entire cavity 24, and the return spring is embedded in the sponge block.

[0028] In the above structure, the sponge block can be stuffed into the cavity 24 together with the return spring in a folded manner and unfolded inside. Then, the sponge porous structure is used to absorb the noise generated by the wheel during driving, while the return spring is used to enhance the restoration effect of the sponge and the cavity 24 after being squeezed, preventing the cavity 24 or the sponge block from deforming due to excessive squeezing.

[0029] In addition, since the sponge is a porous structure, when it is unfolded, air remains inside. During the squeezing process, this air is discharged outward through the through holes, thus forming an air flow. During the driving of the wheel, the air flow can flow along the anti-slip groove 21, thereby improving the cooling effect on the wheel surface and enabling the vehicle to travel a longer distance in a single trip.

[0030] The belt layer 3 is made of rubber, and a cylindrical protruding part 31 is arranged on the top surface facing upwards. At the same time, an installation groove adapted to the protruding part 31 is also provided on the inner ring surface of the tread 2, and the protruding part 31 is inserted into the installation groove, so that the top surface of the belt layer 3 is mutually attached to the inner ring surface of the tread 2.

[0031] A plurality of protruding parts 31 are provided and arranged in a circumferential array with the center of the tread 2. During driving, these protruding parts 31 can form friction with the inner ring surface of the tread 2, thereby enhancing its braking force, and these frictions will also synchronously generate a certain amount of noise. Therefore, in order to reduce the noise and at the same time strengthen the tightness of the fit between the protruding part 31 and the installation groove, a buffer sleeve 32 should also be sleeved on the periphery of the protruding part 31. The buffer sleeve 32 is made of graphene polyurethane composite sponge material, which can not only act as a buffer material but also play a certain noise reduction effect by using the porous structure of the sponge, so as to improve the overall performance of the wheel.

[0032] Tire walls 4 are also provided on both sides of the carcass 1, and the surface of the tire walls 4 should be coated with graphene to improve its high-temperature resistance effect, so as to prevent tire blowout caused by sun exposure in summer.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present invention.
