[0002] Spare tires are usually fixed outside the vehicle for replacing damaged tires in emergency situations. To ensure the safety and stability of the spare tire, the design of the spare tire support is crucial. The spare tire support fixes the spare tire on the vehicle through a stable fixing method to prevent displacement or falling of the spare tire during driving. The design of the support not only considers the stability of the spare tire, but also considers the influence of vibration, impact and other factors during vehicle driving on the spare tire.

[0003] The structural composition of the spare tire support usually includes a support frame, a fixing device and a shock absorption system. The support frame is used to carry and fix the spare tire, the fixing device ensures that the spare tire is stable on the support, and the shock absorption system reduces the impact on the spare tire by absorbing vibration. These components work together to ensure the stability and safety of the spare tire during driving.

[0004] Traditional spare tire supports usually fix the spare tire directly through bolts or clamps due to the simple fixing method, which cannot effectively absorb the vibration and impact generated during vehicle driving. Due to the lack of effective shock absorption devices, vibration is directly transmitted to the spare tire, causing displacement of the spare tire in the support, even leading to damage or premature aging. In addition, continuous vibration also causes loosening or wear of the support components, affecting the stability of the support and the reliability of long-term use. SUMMARY
