Description
TECHNICAL FIELD
[0001] The utility model relates to an adjustable spare tire support assembly. BACKGROUND
[0002] Spare tires are important safety components of vehicles, used to replace when tires are punctured or damaged, to ensure normal driving of vehicles. The performance of spare tire support assembly, as a bearing and fixing device of spare tire, directly affects the safety and convenience of the use of spare tire.
[0003] The traditional spare tire support assembly usually adopts the following structure:
[0004] The external spare tire support fixes the spare tire outside the tail of the vehicle, commonly used in SUVs, off-road vehicles and other models. This structure is simple and reliable.
[0005] The bottom-hung spare tire support fixes the spare tire below the vehicle chassis. This structure saves space and does not affect the appearance of the vehicle, but has a small ground clearance, is easily hit by road obstacles, and is inconvenient to take and place the spare tire.
[0006] For field operations, we mainly use off-road vehicles with girders. In order to increase the support for long-distance crossing, spare tires need to be prepared. In the prior art, such spare tires are usually externally hung on the rear door. During long-distance driving, the weight of the spare tire is large, which will cause the rear door to be pulled down by the force, resulting in deformation of the hinge, so that the rear door cannot be normally closed, and abnormal noise of the door is caused.
[0007] Based on the above problems, we designed an adjustable spare tire support assembly for upgrading and modifying vehicles with girders to provide spare tire clamping capacity. CONTENT OF THE UTILITY MODEL
