EV Battery Transport Container Hook Fixing Without Belt Surface Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle battery transportation containers face issues with belt interference causing damage to the battery surface, inadequate prevention of left-right slip, and unsafe stacking due to uneven coupling of corner support shafts, leading to potential accidents during manual handling.
Innovation Solution
The introduction of a battery fixing hook system with foldable anti-slip parts, ratchet accommodation recesses, and an inclined corner support shaft structure to prevent slip and facilitate safe stacking, ensuring secure fixation and stacking of electric vehicle batteries without interference and injury risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a belt is tightened to fix the electric vehicle battery to the seat base using a ratchet, then the battery is secured against movement, but the belt interferes with the upper surface of the battery and may cause damage
Solution Approach 1:
The patent introduces an intermediary structure (the ratchet mechanism with a hook that engages with the battery frame) that transfers the fixation force away from the battery's upper surface. Instead of the belt directly contacting and pressing on the battery surface, the ratchet hook engages with structural elements of the battery assembly, allowing the belt to apply clamping force to the seat base while the hook provides the actual retention point, thus preventing surface damage while maintaining fixation reliability
2Device complexity
If only a belt is used to fix the electric vehicle battery to correspond to changes in width, then the system remains simple, but left-right slip cannot be prevented when tightening strength decreases
Solution Approach 1:
The fixation system is segmented into multiple functional components: the belt for applying clamping force, the ratchet mechanism for maintaining tension, and the hook for engaging with the battery frame. This segmentation allows each component to perform its specific function optimally - the belt handles width adjustment, the ratchet maintains constant tension, and the hook provides lateral engagement - thereby preventing left-right slip without requiring a completely complex system
3Productivity
If corner support shafts are used to stack seat bases in multiple stages, then stacking efficiency is improved, but uneven coupling causes the upper end portion to hook on the lower opening, delaying work and causing injury risks
Solution Approach 1:
The corner support shaft is designed with an asymmetric structure featuring a tapered geometry where the upper portion has a smaller diameter than the lower portion. This asymmetric design ensures that when the support shaft is inserted into the support shaft insertion groove, the smaller upper portion passes through the larger lower opening smoothly, while the larger lower portion provides stable support. This prevents the hooking problem that occurs with uniform diameter shafts, eliminating work delays and injury risks while maintaining high stacking efficiency

AI summary
Provided is an electric vehicle battery transportation container having a battery fixing hook, one or more foldable anti-slip parts installed on a seat base manufactured in a plate shape having a closed upper surface stand upright to prevent left- right slip and front-rear slip of an electric vehicle battery, a ratchet which tightens a belt to fix the electric vehicle battery to the seat base in a state in which a battery fixing hook connected to the ratchet accommodated in a ratchet accommodation recess part formed in the seat base by the belt is inserted into an assembly hole formed in a lower bracket of the electric vehicle battery loaded on the seat base, and a corner support shaft unevenly coupled to a support shaft insertion groove formed with an inclined structure having a decreasing inner diameter to load seat bases on a transportation vehicle in multiple stages.
