Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bicycle accessories, more particularly to a bicycle rim with buffering function. BACKGROUND

[0002] In the technical field of bicycle rims, there are many technical problems in the existing products that need to be solved urgently, which seriously affect the riding experience and product service life, mainly in the following aspects:

[0003] Firstly, the traditional bicycle rim is too simple in structure design, mainly relying on a single metal rim structure. This simple mechanical structure cannot effectively absorb and disperse the impact force when facing uneven roads, resulting in direct transmission of vibration to the vehicle body and the rider. Especially in bumpy sections or off-road riding, the rim bears a large instantaneous impact force, which can easily cause the rim structure to deform. This deformation not only affects the stability and safety of riding, but also accelerates the wear of the rim, shortens the service life, and more seriously, the deformed rim may cause the tire installation position to deviate, increasing the risk of riding accidents.

[0004] Secondly, although some improved rims have appeared on the market by adding a buffering structure inside the rim to improve the shock absorption performance, these designs still have obvious deficiencies. These improved rims usually use a combination of elastic plates and dampers to try to improve the buffering performance of the rim through elastic deformation and damping shock absorption. However, this design has a major flaw: the tension of the elastic plate is a fixed value and cannot be adjusted adaptively according to different road conditions, rider weight, or riding style. This rigid design results in a buffering system that is either too soft and cannot provide enough support, or too hard and has no obvious shock absorption effect. Especially in the long-term use process, since the tension of the elastic plate cannot be adjusted, the effect of the entire buffering system will be greatly reduced, seriously affecting the riding experience.
