Battery Connector Actuation System Tilting Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery connector systems suffer from tilting due to the 'drawer effect' and are not suitable for simultaneous use with multiple connector pairs or different types, requiring complex redesigns or conversions.
Innovation Solution
The force transmission point is arranged behind the plug-in connection point, allowing the battery-side connector unit to be pulled towards the vehicle-side unit, enabling self-centering and eliminating tilting, while the system design accommodates different connector types with interchangeable holes and a compact, symmetric structure for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the force transmission point is arranged in front of the plug-in connection point (prior art design), then the connector units can be joined together using leverage, but the battery-side connector unit tilts due to the drawer effect
Solution Approach 1:
The patent inverts the conventional force application approach by arranging the force transmission point behind the plug-in connection point instead of in front. This reversal changes the force direction from pushing to pulling, eliminating the drawer effect that causes tilting while maintaining effective connector joining through the same lever mechanism.
2Ease of manufacture
If the system is designed for a specific connector type (prior art), then the structure can be optimized, but complex redesign or conversion is required when using different connector types
Solution Approach 1:
The patent implements universality by designing the base body with a standardized force transmission point arrangement that works with multiple connector types. The pulling mechanism and lever system are configured to accommodate different connector geometries without requiring fundamental redesign, allowing the same basic structure to serve multiple functions with various plug types.
3Quantity of substance
If multiple connector pairs are used simultaneously (prior art), then electrical power capacity increases, but the system requires complex redesign or conversion
Solution Approach 1:
The patent merges multiple connector pairs into a single integrated base body structure with a common lever mechanism. Instead of requiring separate actuation systems for each connector, the design combines them into one unified system where a single lever operation can manage multiple connector pairs simultaneously, reducing overall system complexity while maintaining high power capacity.
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
This design prevents tilting, simplifies manual insertion, and allows for simultaneous connection/disconnection of multiple connector pairs without structural changes, enhancing reliability and flexibility.
Implementation Method 1
an actuating lever (20) which is articulated in a pivotable manner on the base body (12) and can be pivoted about an axis (A1)
Implementation Method 2
a force transmission point (K) between the driver element (22) and the first receiving unit (14), wherein when the actuating lever is pivoted at a force transmission point, a force is exerted by the driver element

AI summary
The present invention relates to a battery connector actuation system for establishing and disconnecting a plug connection between at least one battery-side connector unit and at least one vehicle-side connector unit in a vehicle, in particular a forklift truck, comprising a base body (12); a first receiving unit (14) for the at least one battery-side connector unit, which is movably guided on the base body (12) in an insertion and removal direction; a second receiving unit (18) for the at least one vehicle-side connector unit, which is fixedly associated with the base body (12); an actuating lever (20) pivotally articulated on the base body (12); and at least one drive element (22), which is articulated on one side to the actuating lever (20) and is movably guided on the other side on the base body (12);wherein the first receiving unit (14) and the drive element (22) are arranged such that when the actuating lever (20) is pivoted, a force is transmitted from the drive element (22) to the first receiving unit (14) at a force transmission point, which causes the first receiving unit (14) to move in the insertion or removal direction. According to the invention, the force transmission point between the drive element (22) and the first receiving unit (14) is located behind the connection point of the two connector units in the insertion direction (L) of the battery-side connector unit.
