Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a spare tire lifting device and spare tire suspension structure. Background Technology

[0002] A spare tire is a replacement tire prepared in case the normally used tire malfunctions during vehicle operation, causing the vehicle to be unable to drive normally. Its function is to ensure that the vehicle can drive to the nearest repair shop. The spare tire lifter is used to assist in raising and lowering the spare tire and securing the spare tire in the vehicle. Many cars are equipped with spare tire lifters.

[0003] However, for the under-mounted spare tire suspension structure, the spare tire is usually located at the bottom of the vehicle. When passing through some potholes and high bumps on the road, the lifter lacks an effective positioning structure, which may cause uneven stress on the spare tire after installation. During the vehicle's operation, the spare tire is prone to shaking and falling. At the same time, when the spare tire is loose, it is easy to scrape and collide with the ground or obstacles, which will cause the lifter and the spare tire to malfunction.

[0004] To address the aforementioned issues, this application proposes a spare tire lifting device and spare tire suspension structure for automobiles. Utility Model Content
