Spare Tire Cover Supporting Structure for Vehicle Rear Door
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing spare tire cover supporting structures face challenges with workability and safety due to the spare tire cover falling by its weight, making it difficult to position bolts and nuts during locking, and the varying weight with additional features like license plates and electrical equipment leading to inconsistent falling and potential danger.
Innovation Solution
A spare tire cover supporting structure that includes a transverse rear door, a spare tire cover with a mounting member and a supporting member, where the supporting member restricts the opening movement of the spare tire cover by engaging with a guide and projecting portion, controlling the angles to facilitate easier mounting and locking, and prevent natural opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the spare tire cover is supported only by the mounting member without additional supporting structure, then the structure is simple, but the spare tire cover falls by its weight making it difficult to position bolts and nuts during locking
Solution Approach 1:
The supporting member acts as an intermediary between the spare tire cover and the transverse rear door. It provides a mechanical interface that prevents the cover from falling when the mounting member is detached, thereby enabling proper positioning of bolts and nuts during locking operations without requiring complex additional support structures.
Solution Approach 2:
The supporting member is pre-installed on the transverse rear door before the mounting operation. This preliminary action ensures that when the mounting member is detached, the spare tire cover is already supported in the correct position, preventing it from falling and making it easier to position the bolts and nuts for locking.
2Adaptability or versatility
If the spare tire cover is made heavier by adding features like license plates and electrical equipment, then the functionality is improved, but the falling amount varies and safety is compromised
Solution Approach 1:
The supporting member provides a counterbalancing support force that counteracts the weight of the spare tire cover and its additional features (license plates, electrical equipment). This ensures that regardless of the varying weight, the cover does not fall excessively and maintains safe, consistent positioning during mounting and locking operations.
3Ease of operation
If the mounting member allows easy detachment, then the ease of operation is improved, but the spare tire cover naturally rotates outward due to weight causing safety issues
Solution Approach 1:
The supporting member applies a preliminary anti-action force that prevents the spare tire cover from naturally rotating outward when the mounting member is detached. By providing continuous support, it counteracts the gravitational force that would cause the cover to fall and rotate, thereby eliminating the safety hazard while maintaining easy detachment capability.

AI summary
A spare tire cover supporting structure includes: a transverse rear door, provided on a vehicle; a spare tire cover, including a first end and a second end, the first end supported on the transverse rear door, the spare tire cover operable to cover a spare tire held on the transverse rear door; a mounting member, detachably mounting the second end on the transverse rear door; and a supporting member, provided on one of the transverse rear door and the second end of the spare tire cover. When the second end of the spare tire cover is mounted on the transverse rear door by the mounting member or the second end of the spare tire cover is detached from the transverse rear door, the supporting member positions the spare tire cover relative to the transverse rear door and restricts an opening movement of the spare tire cover.
