Horizontal Stabilization Linkage for Level Cargo Bike Carriages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cargo bikes experience tilting of racks or baskets during turning, leading to item damage and potential falling, especially when carrying larger or heavier loads.
Innovation Solution
A horizontal stabilization structure comprising connecting rods and rods connected to the tilting and carriage devices, maintaining the carriage device level with the ground during tilting to prevent goods from shaking or falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rack or basket is connected to the turning device of the wheels, then the turning operation is facilitated, but the rack or basket tilts along with the body of the bike causing items to collide and get damaged
Solution Approach 1:
The stabilization structure divides the connection system into separate functional segments: the tilting device allows body tilting for turning, while the stabilization structure with connecting rods independently maintains the carriage device level. This segmentation enables the rack to be decoupled from the tilting motion while remaining connected to the turning mechanism.
Solution Approach 2:
The horizontal stabilization structure acts as an intermediary mechanism between the tilting device and the carriage device. It transmits the turning motion while filtering out the tilting motion, allowing the carriage to remain level during turns. The connecting rods with combining parts serve as the intermediary linkage that achieves this motion isolation.
2Adaptability or versatility
If the rack or basket is connected to the turning device, then the turning maneuverability is improved, but items may fall off the rack or out of the basket due to tilting
Solution Approach 1:
The stabilization structure employs dynamic linkages that adapt to the turning motion while maintaining the carriage in a horizontal position. The connecting rods can rotate at their connection points, allowing the system to dynamically respond to turning inputs while keeping the cargo area stable and secure.
3Stability of the object's composition
If a stabilization structure is added to keep the carriage level, then the cargo stability is improved, but the device complexity increases
Solution Approach 1:
The stabilization structure merges the level-maintaining function with the existing tilting and carriage devices. By integrating the connecting rods and combining parts into the overall bike structure, the patent achieves cargo stabilization without adding completely separate, complex mechanisms. The structure combines multiple functions (turning, tilting, and level maintenance) into a unified system.

AI summary
A horizontal stabilization structure (100) which is applied to a cargo bike (200) having a direction controlling device (210), a tilting device (220), and a carriage device (230), includes a first connecting rod (10) and a second connecting rod (20). The first connecting rod (10) has a first connecting end (11) and a second connecting end (12). The first connecting end (11) is connected with an upper tilting rod (220a) of the tilting device (220). The second connecting end (12) has a first combining part (121) and a second combining part (122) protruding toward a lateral side. The first combining part (121) is connected with a lower tilting rod (220b) of the tilting device (220). The second connecting rod (20) has a third connecting end (21) connected with the second combining part (122) and a fourth connecting end (22) connected with the carriage device (230). When the direction controlling device (210) controls the tilting device (220) to tilt, the horizontal stabilization structure (100) keeps the carriage device (230) level.
