AI Technical Summary
The existing spare tire cover has a large gap between the inner surface and the spare tire and a low structural matching degree, resulting in poor restraint of the spare tire in the trunk.
Design a spare tire cover frame, including a composite cover plate, a tire centering plastic part, an annular airbag plate, and a wheel hub equidistant side hole stop block. The annular airbag plate, which can be inflated, pushes the wheel hub equidistant side hole stop block to make it fit tightly against the spare tire. Combined with a slot structure, it can achieve multi-position installation, enhancing the fixing and cushioning effect.
It improves the secure holding of the spare tire and provides vibration damping for items placed on the cover, meeting the restraint requirements of different wheel rims.

Abstract
Claims
1. A spare tire cover panel framework characterized by: The composite cover plate (1), tire centering plastic parts (2), annular airbag pieces (3), and wheel hub equidistant side hole stop blocks (5) are included. Two annular airbag pieces (3) are symmetrically installed on the inner surface of the composite cover plate (1). The composite cover plate (1) located at the annular hole in the middle of each annular airbag piece (3) is welded with a tire centering plastic part (2). A connecting ring seat (4) is installed on the annular surface of each annular airbag piece (3), and a set of wheel hub equidistant side hole stop blocks (5) are distributed on the connecting ring seat (4).
2. A tire cover skeleton according to claim 1, characterized in that: The shape of the tire centering plastic component (2) matches the shape of the structure located in the middle of the wheel hub in the middle of the tire.
3. The tire cover skeleton according to claim 1, wherein: The bottom of the wheel hub equidistant side hole stop block (5) is provided with a slot (510), and the slot (510) is fixed together with the connecting ring seat (4).
4. The spare tire cover framework of claim 1, wherein: The shape of the wheel hub equidistant side hole stop block (5) matches the shape of the hole structure distributed equidistantly around the middle position of the wheel hub located in the middle of the tire.
5. The tire cover skeleton of claim 1, wherein: The tire centering plastic part (2) has an inflation nozzle (6) on its side, and the inflation nozzle (6) is connected to the inside of the annular airbag piece (3).
