Description

Technical Field

[0001] This utility model relates to the field of tire technology, specifically to a tire with low cavity noise. Background Technology

[0002] Tires are circular, elastic rubber products that roll on the ground and are fitted onto various vehicles or machinery. They are typically made of wear-resistant rubber materials, mounted on metal rims, and serve to support the vehicle body, cushion external impacts, make contact with the road surface, and improve vehicle performance. Tire wear resistance is one of the important indicators of its lifespan. Tires with good wear resistance can maintain better performance over long-term use, reducing the frequency of replacement. As a crucial component of vehicle operation, the performance and quality of tires directly affect the vehicle's driving performance and safety.

[0003] A typical tire usually consists of an outer tire, an inner tube, and a bead strip. The outer tire includes: the carcass, a buffer layer, the tread, the sidewall, and the bead. The carcass provides the tire's basic shape and strength. The buffer layer absorbs and disperses impacts from the road surface. The tread is the part of the tire that contacts the ground. The sidewall accommodates the tire's deformation during driving. The bead is the part of the tire that contacts and secures the tire to the rim, ensuring a firm fit. The inner tube is located inside the outer tire and is used for inflation. The bead strip is a ring-shaped rubber band located between the inner tube and the outer tire.

[0004] Traditional tires, when traveling at high speeds on uneven road surfaces, rotate at a certain speed. The deformation of the contact patch causes resonance of the air in the cavity between the tire and the rim, generating tire cavity noise that is transmitted into the vehicle, affecting driver and passenger comfort. To address this issue, some tires incorporate sound-absorbing material of a specific size, strategically placed and adhered to the tire's inner cavity to prevent resonance and reduce cavity noise during high-speed rotation, thus ensuring driver comfort. However, this method suffers from drawbacks. The tire undergoes continuous deformation and stress changes during driving, which can pull or compress the sound-absorbing material, causing its adhesion to gradually decrease and potentially leading to separation and detachment. This compromises the stability of the connection between the tire and the sound-absorbing material. Therefore, a low-cavity-noise tire is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a tire with low cavity noise, thereby solving the technical problem of ensuring the stability of the connection between the tire and the sound-absorbing material.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a low-cavity noise tire, comprising:

[0009] The tire body, and the tread provided on the outer surface of the tire body, with a groove formed on the top of the tread;

[0010] The sound-absorbing ring block is set on the inner wall surface of the tire body, and the top front end and rear end of the sound-absorbing ring block are provided with adhesive surfaces;

[0011] Side clamps are installed on the front and back of the inner wall of the tire body, with the surface of the side clamps tightly adhering to the bottom of the sound-absorbing ring block. Pulling components are added to the top and bottom of the inner cavity of the sound-absorbing ring block. After the sound-absorbing ring block is adhered to the inner wall of the tire body via the adhesive surface, it prevents resonance in the tire cavity, reducing cavity resonance noise generated during high-speed tire rotation and ensuring driver comfort. Because the side clamps are made of elastic material, their position can be adjusted, ensuring a tight fit between the side clamps and the surface of the sound-absorbing ring block. Furthermore, when removing the sound-absorbing ring block, the pulling components can be used to pull it, separating it from the inner wall of the tire body. On one hand, compared to traditional adhesive methods, this structure, with its side clamps, maintains a stable connection between the tire body and the sound-absorbing ring block even after the adhesive surface's adhesion decreases. On the other hand, the elastic side clamps and pulling components facilitate the installation and removal of the sound-absorbing ring block from the tire body.

[0012] Preferably, the pulling assembly includes a main Velcro strap and a pulling handle, and the main Velcro strap is connected to the inner wall of the sound-absorbing ring block. This allows the pulling handle to drive the sound-absorbing ring block through the main Velcro strap.

[0013] Preferably, the top and bottom of the inner cavity of the pull handle are fitted with secondary Velcro straps, which are bonded to the primary Velcro straps. The pull handle is connected to the primary Velcro straps via the secondary Velcro straps, allowing the pull handle to be separated from the primary Velcro straps without removing the sound-absorbing ring block.

[0014] Preferably, a side hook and loop fastener is added to the outside of the main hook and loop fastener, and the side hook and loop fastener is connected to the inner wall of the sound-absorbing ring block. The side hook and loop fastener is bonded to the main hook and loop fastener. When the main hook and loop fastener is not in use, it can be bonded to the side hook and loop fastener to prevent noise and driving interference caused by the main hook and loop fastener due to collision when it rotates with the tire body.

[0015] Preferably, the side locking block includes a side locking protrusion and a side locking concave plate, and an elastic locking block is installed on the side of the side locking protrusion, and the elastic locking block has a T-shaped design. The side locking protrusion can be connected to the side locking concave plate through the elastic locking block.

[0016] Preferably, the side plate has a connecting groove on its side, and the connecting groove is T-shaped. The elastic block corresponds to the shape and position of the connecting groove. When the side plate is connected to the side plate, the elastic block moves along the inside of the connecting groove. Because the elastic block is made of elastic material, it can be separated from the connecting groove by pulling the side plate outward. This not only facilitates the installation of the sound-absorbing ring block but also allows for easy replacement of the side plate according to different usage conditions, ensuring the stability of the connection between the sound-absorbing ring block and the tire body.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a tire with low cavity noise, which has the following beneficial effects:

[0019] This low-cavity-noise tire uses an adhesive surface to bond the sound-absorbing ring block to the inner wall of the tire body. This prevents resonance within the tire cavity, reducing cavity resonance noise generated during high-speed tire rotation and ensuring driver comfort. Because the sidewall clips are made of elastic material, their position can be adjusted, ensuring a tight fit between the sidewall clips and the sound-absorbing ring block surface. Furthermore, the sound-absorbing ring block can be removed by pulling it using a traction component, allowing separation from the inner wall of the tire body. On one hand, compared to traditional adhesive methods, this structure, with its added sidewall clips, maintains a stable connection between the tire body and the sound-absorbing ring block even after the adhesive surface's adhesion decreases. On the other hand, the elastic sidewall clips and traction component facilitate easy assembly and disassembly of the sound-absorbing ring block from the tire body. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution: a low-cavity noise tire, comprising: (see details) Figure 1 The tire body 1, and the tread 14 disposed on the outer surface of the tire body 1, and the tread groove 15 is provided on the top of the tread 14;

[0027] Please see Figure 2 The sound-absorbing ring block 2 is set on the inner wall surface of the tire body 1, and the top front end and rear end of the sound-absorbing ring block 2 are provided with adhesive surfaces 3.

[0028] Side clamps 4 are disposed on the front and back of the inner wall of the tire body 1, and the surface of the side clamps 4 is tightly attached to the bottom of the sound-absorbing ring block 2. Pulling components 5 are added to the top and bottom of the inner cavity of the sound-absorbing ring block 2. After the sound-absorbing ring block 2 is adhered to the inner wall of the tire body 1 through the adhesive surface 3, it is used to block the resonance of the tire cavity, reduce the cavity resonance noise generated during high-speed tire rotation, and ensure the comfort of the driver. Since the side clamps 4 are made of elastic material, the position of the side clamps 4 can be adjusted, and the side clamps 4 can be tightly attached to the surface of the sound-absorbing ring block 2. Furthermore, when removing the sound-absorbing ring block 2, the pulling components 5 can be used to pull the sound-absorbing ring block 2, allowing it to separate from the inner wall of the tire body 1. On the one hand, compared with the traditional adhesive method, this structure has a side locking block 4, which can ensure a stable connection between the tire body 1 and the sound-absorbing ring block 2 even after the adhesiveness of the adhesive surface 3 decreases; on the other hand, due to the elastic side locking block 4 and the pulling component 5, it is easy to disassemble and assemble the sound-absorbing ring block 2 and the tire body 1.

[0029] Please see Figure 3The towing assembly 5 includes a main Velcro strap 6 and a towing handle 7, with the main Velcro strap 6 connected to the inner wall of the sound-absorbing ring block 2. This allows the towing handle 7 to drive the sound-absorbing ring block 2 via the main Velcro strap 6. Secondary Velcro straps 8 are installed at the top and bottom of the inner cavity of the towing handle 7, and these secondary Velcro straps 8 are bonded to the main Velcro strap 6. The towing handle 7 is connected to the main Velcro strap 6 via the secondary Velcro straps 8, allowing the towing handle 7 to be separated from the main Velcro strap 6 without removing the sound-absorbing ring block 2. A side Velcro strap 9 is added to the outer side of the main Velcro strap 6, and the side Velcro strap 9 is connected to the inner wall of the sound-absorbing ring block 2 and bonded to the main Velcro strap 6. When the main Velcro strap 6 is not in use, it can be bonded to the side Velcro strap 9 to prevent noise and driving disruption caused by the main Velcro strap 6 rotating with the tire body 1 due to impact.

[0030] Please see Figure 4 The side-clamping block 4 includes a side-clamping protrusion 10 and a side-clamping concave plate 12, and an elastic clamping block 11 with a T-shaped design is installed on the side of the side-clamping protrusion 10. The side-clamping protrusion 10 can be connected to the side-clamping concave plate 12 through the elastic clamping block 11. The side of the side-clamping concave plate 12 has a connecting groove 13 with a T-shaped design, and the shape and position of the elastic clamping block 11 correspond to those of the connecting groove 13. When the side-clamping protrusion 10 and the side-clamping concave plate 12 are connected, the elastic clamping block 11 moves along the inside of the connecting groove 13. Since the elastic clamping block 11 is made of elastic material, it can be separated from the connecting groove 13 by pulling the side-clamping protrusion 10 outward. This not only facilitates the installation of the sound-absorbing ring block 2, but also facilitates the replacement of the side-clamping protrusion 10 according to different usage conditions, so as to ensure the stability of the connection between the sound-absorbing ring block 2 and the tire body 1.

[0031] This solution involves bonding the sound-absorbing ring block 2 to the inner wall of the tire body 1 via the adhesive surface 3. This prevents resonance in the tire cavity, reduces cavity resonance noise generated during high-speed tire rotation, and ensures driver comfort. Since the side clip 4 is made of elastic material, its position can be adjusted to ensure a tight fit between it and the surface of the sound-absorbing ring block 2. When removing the sound-absorbing ring block 2, the pulling assembly 5 can be used to pull it, separating it from the inner wall of the tire body 1. The pulling handle 7 is connected to the main hook and loop fastener 6 via the secondary hook and loop fastener 8. When the main hook and loop fastener 6 is not in use, it can be bonded to the side hook and loop fastener 9. When the side clip protrusion 10 and the side clip concave plate 12 are connected, the elastic clip 11 moves along the inside of the connecting groove 13. Because the elastic clip 11 is made of elastic material, it can be separated from the connecting groove 13 by pulling the side clip protrusion 10 outwards.
