Collapsible Golf Cart Wheel Interlinking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional foldable golf carts require manual expansion and folding of separate parts, making them inconvenient for simultaneous spreading or bending, and thus not fully practical for storage and use.
Innovation Solution
A collapsible structure that includes an upper frame interlinking rear wheels and a front wheel, allowing them to automatically bend towards or expand from a lower frame during folding or unfolding, enhancing convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If foldable and bendable golf carts are designed to reduce volume for storage, then storage convenience is improved, but the parts need to be manually expanded and folded separately which worsens ease of operation
Solution Approach 1:
The patent combines the front wheel assembly and rear wheel assemblies into a unified collapsible structure where all wheel assemblies are interconnected through the frame. When the handle is moved, all wheel assemblies collapse or expand simultaneously as one integrated unit rather than separate parts, resolving the contradiction by maintaining compact storage volume while enabling single-action operation.
Solution Approach 2:
The collapsible structure is designed to automatically collapse and expand through the mechanical connection between the handle movement and wheel assembly positioning. The structure serves itself by converting the simple handle movement into coordinated wheel assembly collapse/expansion without requiring manual manipulation of each wheel assembly, thus improving ease of operation while maintaining compact form.
2Volume of moving object
If wheel assemblies are designed to collapse separately for compact storage, then volume reduction is achieved, but they cannot be spread or bent at the same time which worsens productivity
Solution Approach 1:
The patent merges all wheel assemblies into a single collapsible system where the front wheel assembly and rear wheel assemblies are mechanically linked through the frame structure. This integration enables simultaneous collapse and expansion of all wheel assemblies through one action, achieving both compact volume reduction and high folding speed productivity.
Solution Approach 2:
The wheel assemblies are pre-positioned and mechanically connected to the handle in such a way that their collapse and expansion paths are predetermined. When the handle is moved, the pre-configured mechanical linkages automatically guide all wheel assemblies to collapse or expand simultaneously at maximum speed, eliminating sequential operation and improving productivity.

AI summary
A collapsible structure for interlinking front and rear wheels of a golf cart is disclosed herein. It comprises an upper frame having two shaft racks, two handles and a supporting rod; a lower frame pivotally connected to the supporting rod and having a first assembling seat pivotally connected to the two shaft racks, two sliding sleeves, each having an upper connecting rod, a rear wheel joint rod and a front wheel push rod, and a second assembling seat having an oblique guide slot and a guiding tooth row in the oblique guide slot for connection to the front wheel push rod; two rear wheel assemblies connected to the two rear wheel joint rods; and a front wheel assembly comprising a guide rod having an annular teeth for engaging with the guiding tooth row in the oblique guide slot.
