Description

Technical Field

[0001] This utility model relates to the field of bicycle tires, specifically a low rolling resistance bicycle tire. Background Technology

[0002] With increasing global emphasis on energy conservation and environmental protection, people are increasingly choosing low-carbon and environmentally friendly modes of transportation. Bicycles, as a green mode of transportation, have gained more popularity. Low rolling resistance tires can reduce energy loss during riding, improve riding efficiency, and make bicycles more energy-efficient, which aligns with the major trend of environmental protection. Therefore, there is a need for low rolling resistance bicycle tires.

[0003] Existing bicycle tires are not conducive to achieving low rolling resistance during operation, and they are not easy to reduce the softening and deformation of the rubber sidewall due to temperature rise. They are also easily affected by temperature. Therefore, there is an urgent need for a low rolling resistance bicycle tire. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a low rolling resistance bicycle tire to solve the problems of existing low rolling resistance bicycle tires, which are not convenient to achieve low rolling resistance, are not convenient to reduce rubber softening and deformation on the tire sidewall due to temperature rise, and are easily affected by temperature.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low rolling resistance bicycle tire, comprising a tire body, a thickened rubber ring on the outer wall of the tire body, sidewalls on both sides of the tire body, and nano-aerogel bonded to the inner wall of the sidewalls.

[0006] The inner wall of the thickened rubber ring is provided with paraffin aluminum oxide composite particles.

[0007] Preferably, the outer wall of the tire body is tightly fitted to the inner wall of the thickened rubber ring, and the outer wall of the thickened rubber ring is configured with a trapezoidal structure.

[0008] Preferably, the inner wall of the tire sidewall is provided with a honeycomb structure, and the inner wall of the tire sidewall is closely attached to the outer wall of the nano-aerogel.

[0009] Preferably, the nano-aerogels are arranged at equal intervals on the inner wall of the tire wall, and the outer wall of the nano-aerogels is arranged in a hexagonal structure.

[0010] Preferably, the outer wall of the paraffin alumina composite particles is tightly fitted to the inner wall of the thickened rubber ring, and the paraffin alumina composite particles are evenly spaced on the inner wall of the thickened rubber ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention achieves a tight fit between the tire body and the thickened rubber ring. The thickened rubber ring reduces deformation when in contact with the ground, thus lowering rolling resistance. At the same time, the tire sidewall achieves a tight fit between the nano-aerogel and the tire. The nano-aerogel has ultra-low thermal conductivity and high elasticity, which reduces the softening and deformation of the rubber on the tire sidewall caused by temperature rise. This invention utilizes a thickened rubber ring to ensure a tight fit between the paraffinic alumina composite particles and the tire body. The paraffinic alumina composite particles undergo a phase transition with temperature changes, absorbing or releasing a large amount of heat while maintaining a relatively stable temperature. When the tire body is driven in a high-temperature environment or generates heat due to friction, the paraffinic alumina composite particles change from a solid to a liquid state, absorbing heat and preventing the tire body from deteriorating due to excessive temperature. In a low-temperature environment, the paraffinic alumina composite particles change from a liquid to a solid state, releasing heat and maintaining the flexibility of the tire body rubber, avoiding the risk of tire blowout due to hardening at low temperatures, and ensuring that the tire body maintains good performance under different temperature conditions.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0015] The embodiments of this utility model will be described below based on its overall structure.

[0016] Please see Figure 1-3A low rolling resistance bicycle tire includes a tire body 1. A thickened rubber ring 2 is provided on the outer wall of the tire body 1. The outer wall of the tire body 1 is tightly fitted with the inner wall of the thickened rubber ring 2, and the outer wall of the thickened rubber ring 2 has a trapezoidal structure. Sidewalls 3 are provided on both sides of the tire body 1. Nano-aerogel 4 is adhered to the inner wall of the sidewall 3. The inner wall of the sidewall 3 has a honeycomb structure, and the inner wall of the sidewall 3 is tightly fitted with the outer wall of the nano-aerogel 4. The nano-aerogel 4 is evenly spaced on the inner wall of the sidewall 3, and the outer wall of the nano-aerogel 4 has a hexagonal structure. The tire body 1 provides a tight fit with the thickened rubber ring 2, reducing deformation upon contact with the ground and lowering rolling resistance. Simultaneously, the sidewalls 3 provide a tight fit with the nano-aerogel 4. The ultra-low thermal conductivity and high elasticity of the nano-aerogel 4 reduce rubber softening and deformation on the tire sidewall due to temperature increases.

[0017] Please see Figure 1-3 A low rolling resistance bicycle tire is disclosed, wherein the inner wall of the thickened rubber ring 2 is provided with paraffin alumina composite particles 5. The outer wall of the paraffin alumina composite particles 5 is tightly fitted to the inner wall of the thickened rubber ring 2, and the paraffin alumina composite particles 5 are evenly spaced on the inner wall of the thickened rubber ring 2. The thickened rubber ring 2 provides a tight fit for the paraffin alumina composite particles 5. The paraffin alumina composite particles 5 undergo a phase transition when the temperature changes, absorbing or releasing a large amount of heat while maintaining a relatively stable temperature. When the tire body 1 is driven in a high-temperature environment or when it generates heat due to friction, the paraffin alumina composite particles 5 change from a solid to a liquid state, absorbing heat and preventing the tire body 1 from deteriorating due to excessive temperature. In a low-temperature environment, the paraffin alumina composite particles 5 change from a liquid to a solid state, releasing heat and maintaining the flexibility of the rubber of the tire body 1, avoiding the risk of tire blowout due to hardening at low temperatures, and ensuring that the tire body 1 maintains good performance in different temperature environments.

[0018] Working principle: When in use, take out the device and place it in the designated position. Inject the paraffin alumina composite particles 5 into the thickened rubber ring 2. Then, heat-vulcanize and fix the thickened rubber ring 2 to the tire body 1. Finally, bond and fix the nano aerogel 4 to the tire sidewall 3. Finally, install the tire body 1 onto the bicycle. This completes the use of the device. The contents not described in detail in this manual are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
