Vehicle Cargo Loading Apparatus with Hinged Upper Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo loading systems for vehicles struggle to efficiently load large-capacity cargo with heavy weights into luggage rooms, particularly in vehicles with high heights, as they require users to manually raise and load the cargo, which is inconvenient and challenging for users like female drivers and seniors.
Innovation Solution
A cargo loading apparatus featuring a rail mechanism with a movable rail, side plates, an upper plate connected via a hinge stopper, and a lifter that allows the upper plate to rotate and tilt upward, enabling users to load large-capacity cargo without direct manual lifting by drawing it rearward from the rear bumper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a storage box structure is used in the rear bumper, then small cargo can be stored, but large-capacity cargo with large volume cannot be stored
Solution Approach 1:
The invention employs a dynamic loading apparatus that transforms from a static storage box structure. The upper plate can rotate upward around the hinge stopper, and the lifter extends to push the upper plate, creating a dynamic loading mechanism that accommodates large-capacity cargo while maintaining ease of operation through automated lifting assistance
2Ease of operation
If a user manually raises large-capacity cargo, then the cargo can be loaded, but it becomes difficult for users with limited strength
Solution Approach 1:
The invention introduces an intermediary loading apparatus between the user and the heavy cargo. The apparatus includes a lifter that pushes the upper plate upward, and the upper plate tilts to receive and push the cargo into the luggage room, thereby mediating the force transmission from the user to the heavy cargo and making it feasible for users with limited strength to load large-capacity cargo
3Adaptability or versatility
If the bumper door is fixed to the rear bumper, then structural integrity is maintained, but the loading apparatus cannot be deployed
Solution Approach 1:
The invention transforms the fixed bumper door structure into a dynamic system. The bumper door is configured to be separable from the rear bumper and can be drawn rearward to deploy the loading apparatus. When not in use, the bumper door returns to its coplanar position with the rear bumper, maintaining structural integrity. This dynamic configuration enables both structural stability and loading functionality
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Significantly improves user convenience by allowing the loading of large-capacity cargo without manual lifting, making it easier for female drivers and seniors to manage heavy and voluminous items, enhancing usability and accessibility.
Implementation Method 1
an upper plate in which a rear side surface is rotatably connected with the side plates through a hinge stopper to be rotatable substantially perpendicularly to the side plates
Implementation Method 2
a rail mechanism including a fixation rail fixed to a rear back beam and a movable rail that moves forward and/or rearward along the fixation rail

AI summary
A cargo loading apparatus of a vehicle luggage room may include a rail mechanism including a fixation rail fixed to a rear back beam and a movable rail that moves forward and/or rearward along the fixation rail, a pair of left and right side plates connected with the movable rail to move together with the movable rail, an upper plate in which a rear side surface is rotatably connected with the side plates through a hinge stopper to be rotatable substantially perpendicularly to the side plates and a rear end is connected with a bumper door, and a lifter installed so that one end of which is connected to a side plate of the side plates and the other end of which is connected to the upper plate, the lifter maintaining a rotational state of the upper plate while a length of the lifter is varied when the upper plate rotates upward around the hinge stopper.
