Battery Slide Restriction Mechanism for Inclined Vehicle Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with slide-out batteries, there is a risk of unintended battery removal due to an inclined vehicle position during parking.
Innovation Solution
A restriction apparatus featuring a movement section, a rotation section, and a restriction section that prevents unintended battery removal by ensuring the battery remains securely in place through a mechanism where the rotation section contacts the restriction section at specific positions, allowing controlled movement between mounting and replacement positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a battery is configured to be pullable between inside and outside of vehicle via slide portion, then ease of operation is improved, but reliability deteriorates due to unintended battery removal
Solution Approach 1:
The rotation section dynamically changes the position of the restriction section between a first position (restricting battery movement) and a second position (allowing battery movement). This dynamic adjustment resolves the contradiction by enabling easy battery removal when needed while preventing unintended removal during normal operation.
Solution Approach 2:
The rotation section acts as an intermediary mechanism between the battery and restriction section. It mediates the conflict between allowing easy battery removal and preventing unintended removal by controlling when the restriction section can contact the battery through rotational movement.
2Reliability
If a restriction mechanism is added to prevent unintended battery removal, then reliability is improved, but device complexity increases
Solution Approach 1:
The rotation section serves multiple functions: it acts as a restriction control mechanism, a movement guide, and a position indicator. By making one component multi-functional, the patent achieves reliable battery position control without proportionally increasing device complexity.
Solution Approach 2:
The rotation section is disposed on either the movement section or vehicle side, nesting the restriction functionality within the existing battery movement structure. This nested arrangement allows the restriction mechanism to be integrated into the slide portion without adding significant external complexity.
3Ease of operation
If the rotation section is disposed on the movement section side, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The restriction apparatus is divided into distinct functional segments: the movement section for battery translation, the rotation section for restriction control, and the restriction section for physical blocking. This segmentation allows each component to be manufactured and assembled independently with standardized tolerances, reducing overall manufacturing precision requirements.

AI summary
A restriction apparatus includes a movement section, a rotation section, and a restriction section, and during when the movement section moves from a replacement position to a mounting position, the rotation section makes contact with the restriction section to rotate from a first position to a second position, and the rotation section passes a position of the restriction section to return to the first position.
