Battery Box Unlocking Mechanism for Angle-Deviation Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing unlocking apparatus for electric vehicle battery boxes, which integrates a suction cup and unlocking mechanism, causes deformation and alignment issues, leading to poor unlocking efficiency and reduced service life due to direct contact with the outer shell.
Innovation Solution
An unlocking apparatus with a drive mechanism, unlocking component, and transmission member that allows axial rotation to adapt to angle deviations and circumferential position adjustments, ensuring accurate alignment and connection without external force, thereby preventing direct contact with the outer shell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the unlocking member is directly arranged on the outer shell of the battery box, then the unlocking apparatus can directly act on the unlocking member to complete the disassembly action, but the strength and sealing of the outer shell are affected, and the outer shell is easy to deform
Solution Approach 1:
The unlocking system is divided into two separate components: the unlocking member remains on the battery box outer shell while the unlocking apparatus is mounted on the battery tray. This segmentation allows the unlocking function to be performed without compromising the structural integrity of the outer shell, as the unlocking apparatus applies force to the unlocking member through a transmission mechanism rather than directly to the shell itself.
Solution Approach 2:
A transmission member acts as an intermediary between the unlocking apparatus and the unlocking member. The transmission member transfers the driving force from the unlocking apparatus to the unlocking member, enabling the unlocking operation without requiring direct contact between the unlocking apparatus and the outer shell, thus protecting the shell from deformation.
2Productivity
If the unlocking member is driven to move to unlock the battery box, then the battery box can be disassembled, but the point-to-point contact between the unlocking apparatus and the unlocking member causes poor alignment accuracy and unlocking failure
Solution Approach 1:
The transmission member is designed with rotational freedom, allowing it to dynamically adjust its orientation to accommodate angular deviations between the unlocking apparatus and the unlocking member. This dynamic adjustment capability ensures reliable alignment and contact during the unlocking process, preventing unlocking failure due to misalignment while maintaining high swapping efficiency.
Solution Approach 2:
The system allows for angular parameter changes in the transmission member's orientation. By permitting the transmission member to rotate and adjust its angle, the system can adapt to variations in positioning accuracy and maintain effective point-to-point contact between the unlocking apparatus and the unlocking member, thereby improving both alignment accuracy and unlocking reliability.
3Device complexity
If the unlocking component is fixed relative to the transmission member, then the structure is simple, but the unlocking component cannot adapt to angle deviation from the standard unlocking position
Solution Approach 1:
The unlocking component is designed to rotate relative to the transmission member around the transmission member's axis. This rotational degree of freedom enables the unlocking component to automatically adapt to angular deviations from the standard unlocking position without requiring complex adjustment mechanisms, thus maintaining structural simplicity while achieving high adaptability.
Solution Approach 2:
The unlocking component's rotational capability allows it to self-adjust to the correct angular position during the unlocking process. Rather than requiring external adjustment mechanisms or complex control systems, the unlocking component autonomously adapts to angle deviations through its inherent rotational freedom, simplifying the overall device structure while improving adaptability.

AI summary
Disclosed are an unlocking apparatus, a swapping device comprising same, and an unlocking control method. The unlocking apparatus is used for unlocking or locking a battery box in a battery bracket on an electric vehicle, and comprises a drive mechanism, an unlocking component, and a transmission member. The drive mechanism drives the unlocking component to move by means of the transmission member, so that the unlocking component drives a locking mechanism on the battery bracket to move to unlock or lock the battery box; the unlocking component is axially rotatable relative to the transmission member to adapt to the angle deviation between the unlocking component and the standard unlocking position on the battery bracket. The swapping device comprises the unlocking apparatus. In this way, even if there is a circumferential deviation, the unlocking component is ensured to be accurately aligned and connected.
