Rocking Vehicle Lock Mechanism Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rocking vehicles face challenges in compactly disposing the rocking lock mechanism, which affects the vehicle's stiffness and space utilization.
Innovation Solution
The rocking lock mechanism is positioned between the head pipe and the main frame, with a disk plate fixed to the rocker arm and a caliper fixed to the body frame, allowing for compact placement while ensuring rocking space and improving stiffness through the use of upper and lower main frames and a bifurcated-shaped main frame portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the rocking lock mechanism is disposed forward of the head pipe, then the rocking lock mechanism can be installed, but the vehicle frame stiffness is reduced and space utilization is poor
Solution Approach 1:
The patent relocates the rocking lock mechanism from the traditional forward position to the space between the head pipe and main frame, utilizing previously underutilized vertical and longitudinal space dimensions. This dimensional repositioning allows the mechanism to be installed without compromising frame stiffness, as it no longer interferes with the forward structural integrity of the vehicle frame.
2Ease of manufacture
If the rocking lock mechanism is disposed forward of the head pipe, then the rocking lock mechanism can be installed, but the space utilization of the vehicle frame is reduced
Solution Approach 1:
The rocking lock mechanism is nested within the space between the head pipe and main frame, utilizing the existing structural voids in the vehicle frame. This nesting approach allows the mechanism to be accommodated within the frame's internal geometry rather than adding external bulk, thereby optimizing space utilization while maintaining installation feasibility.
3Strength
If the rocking lock mechanism is disposed between the head pipe and main frame, then the vehicle frame stiffness is improved, but the installation complexity increases
Solution Approach 1:
The main frame is segmented into upper and lower portions, with the rocking lock mechanism installed in the space between them. This segmentation allows for modular assembly, where the mechanism can be positioned in the intermediate space without requiring complete disassembly of the frame structure, thereby reducing installation complexity while maintaining frame stiffness.
4Ease of operation
If the disk plate is disposed between the head pipe and main frame, then the rocking space is ensured, but the arrangement complexity increases
Solution Approach 1:
The disk plate is positioned at a specific location between the head pipe and main frame where sufficient radial clearance exists. This localized positioning ensures adequate rocking space for the disk plate's rotational movement while avoiding interference with other components. The arrangement leverages the natural clearance in this specific region, minimizing overall complexity while ensuring operational freedom.
