[0002] At present, some tires on the market are equipped with silent cotton to reduce the noise generated by the tires during driving. Such tires are called silent tires. When a silent tire is punctured, it is necessary to use tire repair fluid to repair the tire. The tire repair fluid will inevitably enter the silent cotton during this process, making the silent cotton contaminated and ineffective. After entering the silent cotton near the punctured area, the tire repair fluid will also penetrate into the undamaged area around it, causing the entire silent cotton to be contaminated.

[0003] In response to the problem of noise-reducing cotton contamination caused by tire repair, individual users often choose to discard the tire instead of splitting or cutting off the noise-reducing cotton, resulting in a waste of resources. This is because when installing noise-reducing cotton on a tire, it is usually necessary to grind the inner wall of the tire, and then use rubber strips or hot melt methods to bond the noise-reducing cotton to the tire. Without professional equipment and professional guidance, it is difficult for individual users to disassemble and install the noise-reducing cotton by themselves, and it is extremely difficult to replace the noise-reducing cotton.

[0004] Therefore, how to easily replace the silent cotton so that the silent tire can be reasonably reused is an important topic in the development and promotion of silent tires today. Summary of the invention

[0021] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended invention purpose, the following provides a detailed description of the present utility model in conjunction with the accompanying drawings and preferred embodiments.

[0022] It should be noted that the terms "first", "second", "third", "fourth", etc. in the specification and claims of the present utility model are used to distinguish similar objects and do not necessarily describe a specific order or sequence.

[0023] The orientation terms such as "X direction", "Y direction", and "Z direction" in this specification respectively refer to the common "vehicle body X direction", "vehicle body Y direction", and "vehicle body Z direction" in the automotive field. Among them, the "vehicle body X direction" refers to the length direction of the vehicle body, which is also the front-back direction; the "vehicle body Y direction" refers to the width direction of the vehicle body, which is also the left-right direction; the "vehicle body Z direction" refers to the height direction of the vehicle body, which is also the up-down direction.

[0024] Please refer to Figures 1 to 3The silent tire of the utility model includes a tire body 1 and a plurality of silent modules 2 installed in the tire body. The silent module 2 includes a silent cotton body 21 for sound insulation and noise reduction. A first connecting part 22 is fixedly connected to the silent cotton body 21. The tire body 1 includes a second connecting part 11 arranged on its inner wall. The first connecting part 22 is detachably connected to the second connecting part 11. That is, the silent module 2 is detachably arranged in the tire body 1 through the first connecting part 22. Specifically, in this embodiment, 8 silent modules 2 of the same size are arranged on the inner wall of the tire body 1 at intervals along the circumference of the tire body 1. The cross section of the silent module 2 on the XZ plane is in the shape of a fan ring with the tire wheel center as the center. The fan ring cross sections of all silent modules 2 present the same central angle. The adjacent silent modules 2 are spaced 3 cm apart in the circumference of the tire body 1. The gaps between the silent modules 2 can prevent the tire repair fluid from extending into the entire silent cotton in the tire, and only contaminate the silent cotton at the nailed location. In addition, it also provides a certain degree of convenience for manually disassembling the silent module 2. It is easy to understand that the radius of the fan ring cross section of the silent module 2 in the utility model is actually the thickness of the silent module 2. The greater the thickness of the silent module 2, the greater the radius of the fan ring cross section of the silent module 2. The gaps are set between the silent modules 2, which actually adjusts the total volume of the silent cotton body 21 in disguised form. Since the noise reduction effect of the silent tire depends largely on the thickness and volume of the silent cotton body 21, the silent tire can be provided with a suitable noise reduction effect by adjusting the setting interval of the silent module 2 and the thickness and volume of the silent cotton body 21, so that a certain gap is provided between the silent modules 2 while ensuring the noise reduction effect of the silent tire. In a preferred embodiment of the utility model, the silent modules 2 are spaced 3 to 5 cm in the circumferential direction of the tire body 1. The silent tire of the utility model uses a plurality of silent modules 2 to replace the traditional annular silent cotton. When the tire is repaired by nailing, the tire repair fluid will only penetrate into the silent module 2 near the nailing area, and will not pollute the entire silent tire. There is no need to discard the entire tire or the entire silent cotton during maintenance, and the economic benefit is good. In addition, the silent tire of the utility model also realizes the simple disassembly of the silent module 2 through the first connecting portion 22 and the second connecting portion 11. Individual users and repair shops can easily and conveniently remove and replace any silent module 2 inside the tire according to actual needs during maintenance, which greatly improves the secondary utilization rate of the silent tire.

[0025] Furthermore, the first connecting portion 22 is disposed on one side of the sound-absorbing cotton body 21 facing the inner wall of the tire body 1. The first connecting portion 22 is arranged along the circumferential direction of the tire body 1 on one side of the sound-absorbing cotton body 21 facing the inner wall of the tire body 1. The second connecting portion 11 is disposed on one side of the inner wall of the tire body 1 facing the wheel center, and the second connecting portion 11 is arranged along the circumferential direction of the tire body 1. Specifically, in this embodiment, the first connecting portion 22 and the second connecting portion 11 are a combination of Velcro. The first connecting portion 22 is the fuzzy surface of the Velcro, and the second connecting portion 11 is the hook surface of the Velcro. That is to say, the second connecting portion 11 is the fixed end of the Velcro combination. When disassembling and assembling the sound-absorbing module 2 of the present invention, the sound-absorbing module 2 and the first connecting portion 22 thereon can be separated from the tire body 1 and the second connecting portion 11 thereon only by following the conventional Velcro disassembly method. When preparing the second connecting portion 11 in the present invention, an integral vulcanization technique can be used, that is, before the sound-absorbing module 2 is installed into the tire body 1, the second connecting portion 11 and the inner wall of the tire body 1 are vulcanized and formed together, replacing the omitted tire internal grinding process, so as to reduce the manufacturing cost of the sound-absorbing tire, and can also greatly improve the connection strength between the second connecting portion 11 and the inner wall of the tire body 1. In addition, in this embodiment, the first connecting portion 22 and the second connecting portion 11 are a strip-shaped Velcro combination. Two sets of Velcro combinations are disposed in the tire body 1, that is, two second connecting portions 11 are arranged parallel to each other along the circumferential direction of the inner wall of the tire body 1 and cover the entire circumferential direction of the inner wall of the tire body 1. The sound-absorbing module 2 and the first connecting portion 22 thereon are disposed at corresponding positions on the side close to the wheel center. The first connecting portion 22 and the second connecting portion 11 arranged in this way can realize the installation of the sound-absorbing module 2 at any position on the inner wall of the tire, and the disassembly and installation are extremely simple. In other preferred embodiments of the present invention, the first connecting portion 22 and the second connecting portion 11 can also be Velcro combinations of other shapes, or the first connecting portion 22 is the hook surface of the Velcro and the second connecting portion 11 is the fuzzy surface of the Velcro, as long as the installation is firm and convenient for disassembly and assembly.

[0026] Please refer to Figure 4, Further, the sound insulation module 2 of the present utility model further includes a waterproof layer for waterproofing and sealing the sound insulation cotton body 21. The waterproof layer is wrapped outside the sound insulation cotton body 21, and the sound insulation cotton body 21 and the tire body 1 are separated by the waterproof layer. Specifically, in this embodiment, the waterproof layer includes a first waterproof surface 41 facing the inner wall of the tire body 1, a second waterproof surface 42 facing the wheel center, and a third waterproof surface 43 facing the side wall of the tire body 1. The first waterproof surface 41, the second waterproof surface 42, and the third waterproof surface 43 are integrally connected and jointly waterproof and seal the sound insulation cotton body 21. The first waterproof surface 41 is used to isolate the sound insulation cotton body 21 from the inner wall of the tire body 1. The first connecting portion 22 is disposed on the first waterproof surface 41 along the circumferential direction of the tire body 1 and is integrally fixed to the first waterproof surface 41. The second waterproof surface 42 is used to isolate the sound insulation cotton body 21 from the rim, and the third waterproof surface 43 is used to isolate the sound insulation cotton body 21 from the side wall of the tire body 1. It is easy to understand that the shapes and sizes of the first waterproof surface 41, the second waterproof surface 42, and the third waterproof surface 43 can be adjusted according to the actual shapes of the tire body 1 and the sound insulation cotton body 21, but the third waterproof surface 43 is most preferably a sector ring with the wheel center as the center in the cross-section of the sound insulation module 2 in the X-Z plane. Particularly, the waterproof layer in the present utility model is preferably made by plastic encapsulation because if the plastic encapsulation is in a high-temperature working condition for a long time, such as inside a running tire, it is easy to liquefy on the surface of the sound insulation cotton to form a firm waterproof surface. In this way, there is no need to deliberately select or prepare waterproof materials for the sound insulation cotton, and the overall cost is relatively low. The present utility model realizes the waterproof sealing of the sound insulation cotton body 21 through the waterproof layer wrapping the sound insulation module 2, further avoiding the penetration of the tire repair liquid into other adjacent sound insulation modules 2 during puncture repair, reducing the occurrence frequency of tire repair liquid pollution to the lowest level, and effectively improving the utilization rate and repairability of the sound insulation tire.

[0027] Further, the noise-reducing tire of the present utility model further includes a sensing module for detecting tire pressure, and the sensing module is detachably disposed on the inner wall of the tire body 1. Specifically, in this embodiment, a sensor of the tire pressure monitoring system TPMS is disposed inside the sensing module, and a first connecting portion 22 is disposed outside the sensor module. The sensing module is detachably disposed inside the tire body 1 through the first connecting portion 22 disposed thereon. More specifically, it is mounted on the second connecting portion 11 on the inner wall of the tire body 1 through the first connecting portion 22 disposed thereon. It is easy to understand that since both the sensing module and the noise-reducing module 2 can be mounted on the second connecting portion 11 located on the inner wall of the tire body 1 through their respective first connecting portions 22, the sensing module and the noise-reducing module 2 are interchangeable. When manufacturing the noise-reducing tire, one or several noise-reducing modules 2 can be replaced with the sensing module according to actual needs, or some areas for mounting the noise-reducing module 2 can be replaced with areas for mounting the sensing module, providing a novel mounting method for the tire sensor and to a certain extent contributing to the intelligence and technology of the noise-reducing tire.

[0028] Further, the present utility model also includes an automobile, which includes the aforementioned noise-reducing tire.

[0029] In summary, the noise-reducing tire of the present utility model uses a combination of several noise-reducing modules to replace the traditional integral ring-shaped sound insulation cotton. The noise-reducing modules are waterproof and sealed by a waterproof layer, avoiding the chain pollution of the sound insulation cotton by the tire repair liquid during puncture repair, effectively improving the recycling rate and repairability of the noise-reducing tire. When repairing, there is no need to discard the entire tire or the entire sound insulation cotton, and the economic benefit is good. The present utility model also realizes the simple disassembly and assembly of the noise-reducing module through the first connecting portion and the second connecting portion. Individual users and repair shops can easily remove and replace any noise-reducing module inside the tire according to actual needs, and the user experience is good; the first connecting portion and the second connecting portion can also be used to mount the sensing module, improving the intelligence level of the noise-reducing tire. In addition, the tire body of the present utility model can replace the traditional tire internal grinding process through the one-piece vulcanization technology, reducing the manufacturing cost of the noise-reducing tire.

[0030] The above is only the specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present utility model, and all should be covered by the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
