Bicycle Carrier Tilt Buffering Structure for Impact Cushioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle carrier frames lack effective buffering mechanisms to prevent damage from the heavy weight of bicycles when tilting, which can lead to user injury or component deformation due to direct impact during tilting.
Innovation Solution
A bicycle carrier frame with a tilt buffering apparatus that includes a buffer portion between the connecting rod and fastening bolt, featuring a buffer block with an inclined surface and temporary fixing parts, allowing the frame body to pivot relative to the connecting rod, providing a cushioning effect when tilted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a one-time tilt positioning mechanism is used, then the structure is simple, but the dumping force from bicycle weight can injure users and damage components
Solution Approach 1:
The patent introduces a buffer portion with a buffer block positioned between the connecting rod and the frame body. This buffer block absorbs and cushions the dumping force generated when the bicycle carrier is tilted, preventing direct impact on the connecting rod and fastening bolt. The cushioning effect mitigates the harmful dumping force before it can cause injury or damage, while maintaining a relatively simple overall mechanism.
2Device complexity
If the frame body directly impacts the connecting rod during tilting, then the structure is simple, but component deformation occurs due to friction and impact
Solution Approach 1:
The buffer portion acts as an intermediary element between the frame body and the connecting rod. During tilting, the buffer block contacts the connecting rod first, absorbing impact forces and preventing direct contact between the frame body and the connecting rod. This intermediary structure protects the connecting rod and fastening bolt from deformation caused by direct impact and friction, thereby improving component reliability.
3Reliability
If a buffer portion is added between connecting rod and fastening bolt, then component protection is improved, but device complexity increases
Solution Approach 1:
The buffer portion is designed as a separate, detachable component consisting of a buffer block and a temporary fixing part. This segmentation allows the buffering function to be added independently without redesigning the entire tilt mechanism. The buffer portion can be easily attached and removed, providing component protection while minimizing the increase in overall device complexity.
4Reliability
If the buffer portion is permanently fixed, then component protection is continuous, but storage space is required
Solution Approach 1:
The buffer portion is designed with a temporary fixing part that allows it to be detachably fixed to the frame body or position plates. This dynamic configuration enables the buffer portion to be attached when protection is needed and removed or stored when not in use. The temporary fixing mechanism provides continuous protection during operation while eliminating the need for dedicated storage space, as the buffer portion can be stored anywhere convenient when not required.
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 buffer portion absorbs the impact of the connecting rod, preventing direct contact and potential damage, thus enhancing safety and reducing wear on components, while allowing for easy storage when not in use without additional space requirements.
Implementation Method 1
a buffer portion having an elongated body, with the elongated body having a buffer block... the buffer block has an inclined surface... when the connecting rod is at the tilted position, the buffer block is pressed against the connecting rod on the inclined surface

AI summary
A bicycle carrier with a tilt cushion, including a frame body, a pair of position plates mounted on the bottom of the frame body and provided with a pivot hole, positioning hole and fixing hole. A buffer portion includes a buffer block and temporary fixing part, with the buffer block having a through hole aligned with the fixing hole of the position plates, and an inclined surface. A connecting rod includes a rod pivot hole and rod positioning hole, with a pivot pin passing through the rod pivot hole and fixing hole of the two position plates. A fastening bolt, removably passing through the fixing hole of the position plates and rod pivot hole. When the connecting rod is swung to a tilted position, the buffer portion is held against the connecting rod by the inclined surface.
