Description

Tire sound-absorbing material structure Technical Field

[0001] The invention relates to the technical field of tire accessories, in particular to a tire sound-absorbing material structure. Background Art

[0002] With consumers increasingly concerned about vehicle noise, the tire industry is actively engaged in noise reduction research and development. In particular, with the continued expansion of the new energy vehicle market, the majority of noise originates from the tires due to the inherent technical limitations of these vehicles. Current sound-absorbing or silent tires often incorporate sound-absorbing materials within the tire's inner wall.

[0003] During the processing of applied sound-absorbing tires, most of them use silent cotton for application. The structure of the silent cotton is mostly simple rectangular cotton plates, cotton strips or cotton blocks, which has poor effect and has great limitations on sound absorption effect.

[0005] Technical problems solved

[0006] In view of the deficiencies in the prior art, the present invention provides a tire sound-absorbing material structure, which solves the problems existing in the prior art.

[0007] Technical Solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: a tire sound-absorbing material structure, including a substrate body, with module ends provided at both ends of the substrate body, the module ends including straight cuts and flat bevel cuts, and the inner surface of the substrate body further having a parting groove, and the substrate body is cut into corresponding parting modules by the parting groove.

[0009] Preferably, the module end further comprises a straight cut and an oblique cut, wherein the straight cut and the oblique cut are formed by chamfering the edges of the straight cut and the oblique cut respectively.

[0010] Preferably, the parting groove is provided on either the front side or the back side of the substrate body or on both sides.

[0011] Preferably, the inner surface of the substrate body includes inner surface structures with and without parting grooves. Beneficial effects

[0012] The present invention provides a tire sound-absorbing material structure, which has the following beneficial effects:

[0013] 1. The present invention adopts a combined straight and oblique cut end cutting method, thereby achieving more fitting margins during the internal application of the material. In particular, in the matching application process, the ends can be completely fitted together, which can release stress through the oblique cuts and adhere more firmly through the straight cuts. This greatly improves the processing adaptability of the sound-absorbing material, reduces the processing difficulty of the sound-absorbing material, reduces the internal wind resistance of the tire when rolling, and increases the firmness of the sponge application.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Specific embodiment one:

[0028] As shown in Figures 1, 3, 5, 6, and 9, a tire sound-absorbing material structure includes a substrate body 1, and module ends 2 are provided at both ends of the substrate body 1. The module end 2 includes a straight cut 201a and a flat bevel cut 202a. The module end 2 further includes an inverted straight cut 201b and an inverted bevel cut 202b. The inverted straight cut 201b and the inverted bevel cut 202b are formed by chamfering the edges of the straight cut 201a and the flat bevel cut 202a respectively. Whether it is the straight cut 201a and the flat bevel cut 202a or the inverted straight cut 201b and the inverted bevel cut 202b, when in use, the bonding surface of the substrate body 1 is directly coated with corresponding glue or directly positioned with tape, and pasted on the inner wall of the tire, and the substrate body 1 is evenly bonded to the inner wall of the tire in turn. During processing, the two module ends 2 can be just They can be bonded together by straight cuts, straight cuts 201a or inverted straight cuts 201b, or the terminal assembly requirements after the module end 2 is bonded need to be transitional, and can all be bonded to the inner wall of the tire. The specific bonding method is to select a substrate body 1 of appropriate length according to the design requirements and design working conditions of the tire to achieve good bonding and achieve the designed usage. As shown in the complete simulation diagram of Figure 9, it can be clearly seen that in the process of internal bonding, the inner surface will be more squeezed by bending inward, and the outer surface will be stretched to a certain extent when the length is sufficient, so as to achieve a higher density near the inside and a lower density near the inner wall of the tire. The low-density area absorbs and disperses the noise generated by the tire operation through the gaps in the material, and the high-density area suppresses further transmitted vibrations, thereby achieving better sound absorption effects.

[0029] Specific embodiment two:

[0030] As shown in Figures 2 and 4, a tire sound-absorbing material structure comprises a substrate body 1 further provided with a parting groove 4 on its inner surface. The structure comprises a substrate body 1 with module ends 2 at both ends. The substrate body 1 is divided into corresponding parting modules 3 by the parting groove 4. Based on the technical design and implementation of the first embodiment, the parting groove 4 is provided on the inner surface of the substrate body 1 to divide the entire substrate body 1 into multiple parting modules 3. The application operation to the inner wall of the tire is consistent. When the entire substrate body 1 is fully applied, the parting groove 4 on its inner surface allows the entire substrate body 1 to be more easily bent. The density uniformity of the entire sound-absorbing material is slightly better than that of the first embodiment, but the peak sound absorption efficiency is slightly lower than the technical solution of the first embodiment.

[0031] Specific embodiment three:

[0032] As shown in FIG7 , a tire sound-absorbing material structure is provided. Further, the module end 2 at the end of the substrate body 1 is further shaped as a fully chamfered interface. Furthermore, the inner surface of the substrate body 1 under the fully chamfered interface includes inner surface structures with and without parting grooves 4. Parting grooves 4 can be provided on both the front and back sides of the sound-absorbing material. As shown in FIG10 and FIG11 , the block structure can be butted / welded / bonded to each other, or can be directly positioned inside the tire by gluing without butting and retaining a certain gap. The specific number of segments of the block structure can be determined based on actual processing requirements.

[0033] Specific embodiment four:

[0034] As shown in FIG8 , a tire sound-absorbing material structure is provided, wherein the module end 2 at the end of the substrate body 1 is further shaped as a direct opening, and the inner surface of the substrate body 1 under the direct opening shape includes an inner surface structure with a parting groove 4 and an inner surface structure without a parting groove 4.

[0035] Specific embodiment five:

[0036] A tire sound-absorbing material structure, wherein the module end head 2 at the end of the substrate body 1 is further shaped as an oblique interface, and the oblique interfaces cooperate with each other, and the end surfaces of the module end heads 2 after the circular ring combination are parallel to each other.
