Steering Bracket Quick-Release Structure for Foldable Transport Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and disassembly of steering and body brackets in transportation tools like mobility scooters and kick scooters are cumbersome, especially when front-wheel driven, making it difficult to mount the steering bracket and front wheels as a whole before attaching the body bracket.
Innovation Solution
A detachable fixing structure with a fixing sleeve and fixing column allows the steering bracket to rotate about the axis, featuring a movable member linked to an operation portion that releases the positioning member when rotated, enabling easy assembly and disassembly by inserting or removing the fixing column into the sleeve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the steering bracket and body bracket are rotationally fixed to facilitate steering, then the steering function is improved, but the assembly and disassembly process becomes troublesome and time-consuming
Solution Approach 1:
The rotational connection between steering bracket and body bracket is segmented into a detachable fixing structure consisting of a fixing sleeve and fixing column. This allows the connection to be divided into separate components that can be easily assembled and disassembled, resolving the contradiction between maintaining rotational steering capability and reducing assembly time.
Solution Approach 2:
The fixing structure incorporates a movable member that can dynamically transition between locked and unlocked positions. When the movable member is in the locked position, it secures the fixing column in the fixing sleeve to maintain steering function. When unlocked, it allows quick disassembly, thus resolving the time loss contradiction.
2Adaptability or versatility
If the steering bracket is made foldable to facilitate storage and transportation, then the storage convenience is improved, but the assembly process becomes more troublesome
Solution Approach 1:
The detachable fixing structure segments the connection between steering bracket and body bracket, allowing the steering bracket to be easily detached and folded. This segmentation simplifies both the folding mechanism for storage and the assembly process, resolving the contradiction between storage convenience and assembly ease.
3Productivity
If a detachable fixing structure is introduced to enable easy assembly and disassembly, then the assembly speed is improved, but the device complexity increases
Solution Approach 1:
The fixing column is inserted into and nested within the fixing sleeve, creating a compact detachable connection. This nesting arrangement allows the fixing components to be stored within each other when not in use, reducing overall complexity while maintaining fast assembly capability.
Solution Approach 2:
The movable member automatically locks the fixing column in position through a self-locking mechanism involving positioning grooves and positioning members. This self-service feature eliminates the need for additional locking operations or complex fastening systems, thereby increasing assembly speed without proportionally increasing device complexity.

AI summary
The present invention relates to a fixing structure for a steering bracket and a body bracket of a transportation tool. A fixing structure for a steering bracket and a body bracket of a transportation tool is provided. The steering bracket comprises an operation portion used for fixing a handlebar and a connecting portion used for fixing a front wheel; the operation portion and the connecting portion are rotationally fixed; a rotating axis is arranged in the left-right direction, and a detachable fixing structure is arranged between the connecting portion and the body bracket; the detachable fixing structure comprises a fixing sleeve and fixing column capable of extending into the fixing sleeve; a first positioning groove is formed on the inner wall of the fixing sleeve and fits with a positioning member; and, when the operation portion rotates, the operation portion drives a movable member to move, so that the position limitation of the positioning member is canceled out. The present invention can realize the quick assembling and disassembling of the steering bracket and the body bracket, and is very convenient to use. Moreover, the structure of the present invention does not affect the normal folding and use of the transportation tool, and the structure is compact.
