Vehicle Trunk Mat Limit Mechanism for Easier Luggage Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle trunk mats with limit devices for luggage require inconvenient operations to adjust the position of the limit rod, as they necessitate constant pressing of the connecting rods to move the sliding bases, and the support rods are prone to deformation and instability due to high center of gravity.
Innovation Solution
A vehicle trunk mat with a sliding rail, support rod, and height switching assembly that allows for easy adjustment of the limit rod position through a pressing block and lifting rod mechanism, combined with a reinforcing rod and transmission assembly to enhance stability and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sliding base is unlocked by pressing the connecting rod through the stopper, then the connecting rod can be released and restored via elastic component to lock the sliding base, but when the position of the limit rod is to be adjusted, the two connecting rods must always be pressed to move the sliding seat, resulting in inconvenient operation
Solution Approach 1:
The lifting rod is nested inside the support rod, with the limit block attached to the lifting rod. When the pressing block is pressed, it drives the lifting rod to move relative to the support rod, which in turn moves the limit block along the sliding rail to detach from or engage with the limit groove. This nested structure allows the limit rod position to be adjusted by pressing only the pressing block once, rather than continuously pressing multiple connecting rods.
Solution Approach 2:
The limit block is pre-positioned in the limit groove to lock the support rod in place. When adjustment is needed, the pressing block is pressed to drive the lifting rod and limit block to detach from the limit groove in advance, allowing the support rod to be freely moved to the desired position before the limit block re-engages with the next limit groove position.
2Length of moving object
If the support rod is made tall to provide sufficient lifting height for the limit block, then the limit block can be detached from the limit groove, but the support rod becomes prone to deformation and instability due to high center of gravity
Solution Approach 1:
The lifting rod is nested inside the support rod, allowing the lifting function to be achieved through the inner lifting rod's movement rather than requiring the entire support rod to be excessively tall. The limit block attached to the lifting rod can be raised and lowered along the sliding rail by the lifting rod's movement, achieving the necessary lifting height without making the outer support rod overly tall and unstable.
Solution Approach 2:
The support structure is segmented into an outer support rod and an inner lifting rod. The support rod provides structural stability and remains relatively short, while the lifting rod performs the lifting function by moving vertically within the support rod. This segmentation allows the stable support function and the lifting function to be separated, maintaining stability while achieving sufficient lifting height.

AI summary
The present application relates to the technical field of loading luggage in a vehicle trunk, and particularly to a vehicle trunk mat with limit device for luggage including a luggage mat; a sliding rail fastened on the luggage mat, and a support rod slidably connected to the sliding rail, the support rod is perpendicular to the luggage mat. A lifting rod is slidably arranged in the support rod, an end of the lifting rod is fastened with a limit block. The sliding rail is configured with a plurality of limit grooves. When the limit block is inserted into the limit groove, the support rod is locked. A top of the support rod is slidably connected with a pressing block, a height switching assembly is connected between the pressing block and the lifting rod, the height switching assembly is adaptive for switching different height positions of the lifting rod.
