Foldable Vehicle Bicycle Stand With Locking Support Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted bicycle stands are either inconvenient to mount and maintain due to high positioning, prone to damage, or occupy excessive space due to fixed support structures without folding or adjusting capabilities.
Innovation Solution
A vehicle-mounted bicycle stand with a mounting seat connected to a square-opening base, a vertically fixed support rod, and a locking mechanism that allows for quick unfolding, folding, and height adjustment, featuring a screw rod and tightening mechanism for secure mounting and a telescopic support rod for adaptability to different bicycle sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle top fixing type is used, then the bicycle can be fixed on the vehicle, but the height of the entire vehicle increases and the bicycle is prone to damage from scraping with trees
Solution Approach 1:
The support rod is designed to be rotatable relative to the mounting seat, allowing the bracket to be in a rearward unfolded state during bicycle mounting/dismounting and a downward folded state during vehicle operation. This dynamic configuration resolves the contradiction by enabling the structure to adapt between two states: extended for usability and retracted for compactness and safety.
2Reliability
If a traditional rear fixing type with a fixed support structure is used, then the bicycle can be fixed on the vehicle, but a large space is occupied when the structure is not in use
Solution Approach 1:
The support rod rotates between a vertical extended position for bicycle support and a folded position parallel to the vehicle body, reducing the volume occupied by the support structure from a large extended configuration to a compact folded state that integrates with the vehicle profile.
Solution Approach 2:
When folded, the bracket and support rod structure nests against the vehicle body, with the support rod folding parallel to the vehicle and the bracket folding inward, creating a compact nested configuration that minimizes the space occupied by the support structure.
3Device complexity
If a traditional rear fixing type without adjusting function is used, then the structure is simple, but it can only adapt to bicycles of a single form or model
Solution Approach 1:
The support rod length is adjustable through a telescopic mechanism with locking features, allowing the height and position parameters of the bracket to be changed. This enables the same device to adapt to different bicycle types and models without increasing overall structural complexity, as the adjustment mechanism integrates into the existing support structure.
4Stability of the object's composition
If a traditional rear fixing type without rotating function is used, then the structure is stable, but it is inconvenient to mount and dismount the bicycle
Solution Approach 1:
The support rod is designed with rotational capability relative to the mounting seat, allowing the bracket to swing outward to a rearward unfolded state during bicycle mounting and dismounting operations, providing adequate operational space and ease of access. During vehicle operation, the support rod returns to a vertical stable position, maintaining structural stability. The dynamic rotation mechanism thus reconciles the need for stability during operation with the need for ease of operation during mounting/dismounting.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a compact, labor-saving, and reliable bicycle stand that reduces height, increases operational space, and ensures safety by preventing the bicycle from hitting the ground, while allowing for easy mounting and dismounting, and adapting to various bicycle specifications.
Implementation Method 1
a head of the screw rod 15 passes through the insertion rod 11 forward and extends to the outside of the mounting seat 1, and a tightening part 16 is fixed at an end of the screw rod; and when the tightening part 16 is rotated, the screw rod 15 can be driven to rotate, and the support block 13 can move forward
Implementation Method 2
the locking and fixing mechanism is provided with a first elastic component for enabling the shift block 42 to have a trend of rotating rearward and driving the slide block 44 to move upward, or enabling the slide block 44 to have a trend of moving upward and driving the shift block 42 to rotate rearward
