Foldable Vehicle Linkage and Synchronized Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable vehicles require complex and cumbersome operations for folding and unfolding, often necessitating multiple steps and compromising stability due to lack of linkage mechanisms between chassis components, leading to increased volume and failure rates.
Innovation Solution
A foldable vehicle design incorporating a foldable linkage and vehicle lock system that synchronizes the movement of the head assembly, front chassis, and rear chassis using a linkage controller, allowing for one-step folding and unfolding while ensuring stability through interlocking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate locking mechanisms are used for head-chassis and front-rear chassis connections, then the vehicle can be locked at multiple positions, but the operation becomes complex and tedious requiring multiple steps
Solution Approach 1:
The patent combines multiple locking mechanisms (head-chassis locking and front-rear chassis locking) into a single integrated locking device. When the user operates one locking mechanism, it simultaneously controls both locking functions through a linkage system, reducing the number of操作步骤 from multiple separate operations to a single unified operation while maintaining multi-position locking capability
Solution Approach 2:
The patent introduces a linkage mechanism as an intermediary between the user's single locking operation and the multiple locking positions. This linkage system transmits and coordinates the locking action across different components (head assembly, front chassis, rear chassis), enabling one operation to achieve multiple locking functions simultaneously
2Device complexity
If the chassis is not folded, then the structure is simpler, but the volume after folding remains relatively large
Solution Approach 1:
The patent divides the chassis into separable segments (front chassis and rear chassis) that can be independently folded relative to each other. This segmentation allows the vehicle to achieve a more compact folded volume by collapsing the chassis segments together, while the modular design keeps the overall structure relatively simple and manageable
3Volume of moving object
If as many folding times as possible are adopted to reduce folded volume, then the folded volume decreases, but the locking mechanism becomes more complicated and stability decreases
Solution Approach 1:
The patent merges multiple locking functions into a single coordinated locking mechanism that operates simultaneously at different folding positions. This unified approach reduces the complexity that would arise from having separate locking mechanisms for each folding stage, while still providing stable locking at multiple positions through the integrated design

AI summary
A foldable vehicle includes head and chassis assemblies hinged together, and a foldable vehicle lock. The head assembly includes upper and lower heads hinged together. The chassis assembly includes front and rear chassis hinged together. A foldable linkage folds and unfolds the foldable vehicle. The foldable linkage is hinged with the head assembly, the front and rear chassis such that the head assembly, the front and rear chassis are driven to conduct relative movement to perform the corresponding foldable and unfoldable operations. The foldable vehicle lock includes a head locking assembly to lock the upper head with the lower head, a chassis locking assembly to lock the front chassis with the rear chassis, and a whole vehicle locking assembly to lock the head assembly with the chassis assembly. The chassis and whole vehicle locking assemblies are controlled synchronously by a linkage controller.
