Scissor-Lift Charging Head Alignment With Crossed Swing Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle power supply devices with scissor-fork lifting mechanisms have unstable structures and poor alignment during power supply due to non-cross-connected swing rods, leading to inefficient power transfer.
Innovation Solution
A vehicle power supply device with cross-arranged swing rods hinged to a fixed base and power supply head, utilizing guide rails and slide rods for stable movement and alignment, and a drive mechanism to convert rotational motion into linear motion for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two small swing rods are directly hinged with the power supply head without cross-connection, then the device structure is simpler, but the power supply head swing is too large and alignment during power supply is poor
Solution Approach 1:
The patent merges the two separate small swing rods into a single cross-connected swing rod structure. The swing rod is cross-connected at its midpoint to the fixed base, creating a unified structure that replaces the two separate rods. This merging reduces structural complexity while simultaneously constraining the power supply head swing to improve alignment precision during power supply.
Solution Approach 2:
The cross-connected swing rod acts as an intermediary structure between the fixed base and the power supply head. By introducing the cross-connection point as an intermediate constraint, the system achieves better control over the power supply head movement without directly complicating the overall structure. The intermediary cross-connection provides the necessary geometric constraint to reduce swing while maintaining structural simplicity.
2Device complexity
If the swing rods are not cross-connected, then the device structure is simpler, but the structure stability and movement stability are poor
Solution Approach 1:
The patent merges the two separate small swing rods into a single cross-connected swing rod structure. The swing rod is cross-connected at its midpoint to the fixed base, creating a unified structure that replaces the two separate rods. This merging reduces structural complexity while simultaneously constraining the power supply head swing to improve alignment precision during power supply.
Solution Approach 2:
The cross-connected swing rod creates an asymmetric structural configuration where the midpoint of the swing rod is fixed to the base, dividing the rod into two unequal arms relative to the power supply head. This asymmetric arrangement provides inherent structural stability by creating a geometric constraint that prevents excessive swinging while maintaining overall structural simplicity.
3Stability of the object's composition
If the swing rods are cross-arranged and hinged, then the structure stability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the two separate small swing rods into a single cross-connected swing rod structure. The swing rod is cross-connected at its midpoint to the fixed base, creating a unified structure that replaces the two separate rods. This merging reduces structural complexity while simultaneously constraining the power supply head swing to improve alignment precision during power supply.
