Battery Seating Alignment Using Pins for Vibration-Safe Swapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery swapping systems face issues with misalignment of new batteries and vehicle battery receiving spaces during the swapping process, leading to potential damage to both the battery and the vehicle body due to vibrations generated by the battery transfer apparatus.
Innovation Solution
A battery transfer apparatus with a seating portion and position alignment mechanism, including position fixing pins and a horizontal alignment portion, ensures precise alignment of the battery and the vehicle battery receiving space through corrective movements and rotations, utilizing sensors and controllers to determine and apply necessary corrections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the battery transfer apparatus transfers the new battery to the battery receiving space based on the input path, then the battery swapping process can be completed, but the new battery may be transferred along a different path due to vibrations, causing misalignment between the battery and battery receiving space
Solution Approach 1:
The patent introduces a position alignment portion that performs preliminary positioning of the battery before it is transferred to the battery receiving space. This preliminary action ensures that even if vibrations occur during transfer, the battery maintains proper alignment with the receiving space, preventing misalignment damage while maintaining efficient swapping operations
Solution Approach 2:
The position alignment portion acts as an intermediary mechanism between the battery transfer path and the battery receiving space. It provides a stable reference frame that compensates for vibrations during transfer, ensuring accurate alignment without requiring the battery to follow the input path perfectly
2Productivity
If the battery and battery receiving space are not aligned properly during battery swapping, then the swapping process may be faster, but the battery and vehicle body may be damaged
Solution Approach 1:
The position alignment portion provides beforehand cushioning by pre-positioning the battery in the correct alignment before the transfer operation completes. This prevents potential damage from misalignment without slowing down the swapping process, as the alignment is established in advance rather than requiring correction during or after transfer

AI summary
A battery transfer apparatus for battery swapping that transfers a battery to a vehicle for which the battery swapping is required includes a seating portion that provides a seating space in which the battery is accommodated and a position alignment portion that allows the seating portion to move so that relative positions of the battery accommodated in the seating space and a battery receiving space of the vehicle are aligned.
