Golf Bag Cart Rear Wheel Interlock Folding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable golf bag carts require manual adjustment and folding of rear wheels, making the process inconvenient and inefficient.
Innovation Solution
A rear wheel interlock folding mechanism that includes a lower frame, upper frame, and rear-wheel sets, where a bending base of the rear-wheel set is moved along with the upper frame folding toward the lower frame, allowing the rear wheel to move closer to the lower frame, facilitated by an auxiliary support rod with a brush for cleaning and a link mechanism for easy folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment and folding of rear wheels is required, then the structure can be simple, but the ease of operation deteriorates
Solution Approach 1:
The patent merges the rear wheel folding mechanism with the upper frame folding mechanism by connecting the bending base to the upper-frame connecting rod through a link. This integration allows the rear wheels to fold automatically when the upper frame is folded, eliminating the need for separate manual wheel adjustment while maintaining structural coherence.
Solution Approach 2:
The rear wheel folding mechanism performs self-service by automatically moving the rear wheels to the folded position through the interlock connection with the upper frame. The bending base rotates automatically as the upper frame connects to the lower frame, eliminating the need for users to manually adjust the rear wheels during the folding process.
2Ease of operation
If rear wheels are moved automatically during folding, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The patent merges the rear wheel folding mechanism with the upper frame folding mechanism by connecting the bending base to the upper-frame connecting rod through a link. This integration allows the rear wheels to fold automatically when the upper frame is folded, eliminating the need for separate manual wheel adjustment while maintaining structural coherence.
Solution Approach 2:
The upper-frame connecting rod serves multiple functions: it connects the upper frame to the lower frame for folding, and simultaneously drives the rear wheel bending base through the link mechanism. This multi-functionality reduces the need for separate dedicated mechanisms, balancing automation with controlled complexity.
3Volume of moving object
If the golf bag cart is made foldable to reduce storage volume, then the volume decreases, but the ease of operation worsens due to manual wheel adjustment
Solution Approach 1:
The rear wheel folding mechanism performs self-service by automatically moving the rear wheels to the folded position through the interlock connection with the upper frame. The bending base rotates automatically as the upper frame connects to the lower frame, eliminating the need for users to manually adjust the rear wheels during the folding process.
Solution Approach 2:
The patent merges the rear wheel folding mechanism with the upper frame folding mechanism by connecting the bending base to the upper-frame connecting rod through a link. This integration allows the rear wheels to fold automatically when the upper frame is folded, eliminating the need for separate manual wheel adjustment while maintaining structural coherence.

AI summary
A rear wheel interlock folding mechanism of a golf bag cart is revealed. An upper frame is fixed on an upper-frame connecting rod connected to a lower frame. A rear-wheel connecting rod is fixed on the lower frame and behind the upper-frame connecting rod. A rear-wheel set is set on each end of the rear-wheel connecting rod. The rear-wheel set includes a fixing base fixed on the rear-wheel connecting rod, a bending base pivotally connected to the fixing base, a rear wheel pivotally disposed on the outer end of the bending base, a rotating seat fixed on the upper-frame connecting rod and a link between the bending base and the rotating seat. Thereby the bending base is also moved to drive the rear wheel moving close to the lower frame when the upper frame is folded toward the lower frame. Thus the golf bag cart is folded conveniently.
