Spare tire cover plate for automobile

Abstract

The invention discloses a spare tire cover plate for an automobile, and particularly relates to the field of automobile accessories. The spare tire cover plate comprises a cover plate body, a positioning piece is arranged in the middle of the inner wall of the cover plate body, a deformation gasket is fixedly arranged on the outer wall of the cover plate body, the positioning piece comprises a connecting table and a protective pad, a first air storage cavity is formed in the protective pad, an air guide pipe is arranged between the protective pad and the deformation gasket, a storage cavity isformed in the connecting table, and a plurality of fixing holes are evenly formed in the bottom of the storage cavity. Through cooperative use of the protective pad and the deformation gasket, when the cover plate body is closed, the protective pad is extruded by a spare tire to drive the first air storage cavity to contract, redundant air in the first air storage cavity is conducted into the first air storage cavity through the air guide pipe, and the protective pad is driven to expand and deform; and the gap between the outer edge of the main body plate and a spare tire storage cavity is sealed, so that the spare tire is prevented from being damaged by leakage of oil products such as lubricating oil stored in a trunk, and the service life of the spare tire is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of auto parts, and more specifically, the invention relates to a spare tire cover plate for an automobile.

Problems solved by technology

[0004] When the existing spare tire cover is in use, dust or sundries will often fall due to the gap between the spare tire cover and the storage cavity due to insufficient sealing, because the main component of the tire is rubber, and What rubber is most afraid of is the erosion of various oil products. If the car owner often stores lubricating oil and other oil products in the trunk, because of the existence of gaps, once the oil touches the tires, it will cause the tires to bulge and corrode, which will greatly reduce the wear and tear of the tires. service life
