Golf Trolley Front Wheel Rotating Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf trolleys with folding front wheels still occupy significant space due to the perpendicular orientation of the folded front wheel, making storage inconvenient.
Innovation Solution
A rotating positioning member for the front wheel that allows it to lean horizontally against the lower frame of the trolley when folded, utilizing a front wheel set with an inclined guide slot, connecting rod, and pivot mechanism to reduce volume and space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the front wheel is folded backward directly while maintaining its original orientation, then the folding action is simple, but the front wheel occupies significant vertical space and the overall volume remains large
Solution Approach 1:
The front wheel is designed with a dynamic positioning mechanism that allows it to rotate from a vertical folded position to a horizontal leaning position against the lower frame. This dynamic repositioning reduces the vertical footprint and overall volume of the folded trolley, resolving the contradiction between simple folding and compact storage volume.
Solution Approach 2:
The invention changes the spatial dimension of the folded front wheel from vertical orientation to horizontal orientation by having it lean against the lower frame. This dimensional transformation significantly reduces the vertical space occupied during storage, addressing the volume reduction requirement.
2Device complexity
If the front wheel is folded to a perpendicular position to the ground, then the folding structure is straightforward, but the storage space required remains insufficient
Solution Approach 1:
The front wheel assembly incorporates a dynamic mechanism that enables the wheel to rotate from a static perpendicular position to a horizontal leaning position against the lower frame. This dynamic adjustment minimizes the storage area required, as the horizontal orientation allows the wheel to nestle within the trolley frame structure rather than occupying external vertical space.
3Ease of manufacture
If a simple folding mechanism is used for the front wheel, then the manufacturing cost is low, but the storage convenience is poor
Solution Approach 1:
The invention introduces a dynamic positioning mechanism with a connecting rod, pivot block, and guide slot that enables the front wheel to automatically rotate to a horizontal leaning position during the folding process. This mechanism, while slightly more complex than a simple fold, provides significant storage convenience by reducing the vertical footprint, thereby improving ease of operation for storage purposes.

AI summary
A rotating positioning member of a front wheel of a golf trolley is revealed. A front wheel set is disposed at a front end of a lower frame and including a front wheel base fixed on the lower frame, a front wheel frame, and a front wheel pivotally connected to the front wheel frame. The front wheel base is mounted with an inclined guide slot. A connecting rod is formed on the front wheel frame and pivotally connected to the inclined guide slot. Thus the connecting rod drives the front wheel frame to rotate 90 degrees and the front wheel frame further drives the front wheel to horizontally lean against the lower frame when the front wheel frame is rotated toward the lower frame in the inclined guide slot due to the connecting rod. Thus the golf trolley is easy to fold up for storage.
