Rear Vehicle Roof Storage Hook Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing roof fixing device for vehicles requires two operations to engage the hook with the striker, and the storage process can cause the roof to twist, necessitating precise alignment which is difficult to achieve.
Innovation Solution
A rear vehicle-body structure with a fixing device that includes a hook-position changing member, adjacent to the holding device, allowing the hook to be changed from its open position to a pre-lock position during storage, improving operability and alignment accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hook is changed from open position to pre-lock position by pressing against the press portion during storage, then the operability is improved, but the manufacturing precision becomes more difficult to achieve due to roof twisting
Solution Approach 1:
The press portion is positioned to automatically change the hook from open position to pre-lock position during the storage process, performing the position change action in advance before the roof is fully stored, eliminating the need for additional lever operations
Solution Approach 2:
The press portion acts as an intermediary element between the hook and the roof structure, using the roof's own movement during storage to automatically press the hook into the pre-lock position, thereby achieving position change without additional operational complexity
2Reliability
If two operations are required to engage the hook with the striker, then the locking is secure, but the device complexity increases
Solution Approach 1:
The system uses the roof's own storage movement to automatically perform the hook position change from open to pre-lock, making the system self-servicing and eliminating the need for separate operational steps
Solution Approach 2:
The hook position change function is merged with the roof storage process, so that the same movement that stores the roof also automatically changes the hook position, reducing the number of separate operations required

AI summary
A holding device to hold an openable roof when the openable roof is stored is provided at a front portion of a storage partition. There is provided a changing member to change a hook having an open position from its open position to its pre-lock position by being pressed down by the hook taking the open position when the openable roof is operated for storage in the storage partition. The changing member is provided adjacently to the holding device. Thereby, a rear vehicle-body structure of a vehicle which can surely change the hook from its open position to its pre-lock position can be provided.
