Steering Apparatus Integrated Guide Lock Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing steering apparatus for vehicles requires a large number of construction parts due to the need for welding the steering lock device to the upper tube, making it complex and difficult to mount.
Innovation Solution
A steering apparatus design where the steering lock device is integrated with the guide bracket and lock bracket as a single piece, reducing the number of parts and using a cylindrical lower housing for enhanced stiffness, allowing for easier assembly and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the steering lock device is welded to the upper tube with multiple separate parts, then the locking function is reliable, but the number of construction parts increases and assembly becomes difficult
Solution Approach 1:
The guide bracket and lock bracket are merged into a single integrated component that is fixed to the upper tube. This integration reduces the number of separate parts while maintaining the reliable locking function through the combined guide and lock features of the unified bracket structure.
2Strength
If multiple separate parts are welded together to form the steering lock device, then the structural integrity is maintained, but the assembly process becomes time-consuming and complex
Solution Approach 1:
The guide bracket and lock bracket are combined into one piece that is fixed to the upper tube, reducing the number of welding operations and assembly steps while maintaining structural integrity through the unified design and single fixation process.
3Volume of moving object
If the cylindrical portion has an undercut to prevent overlapping, then the space is optimized, but the stiffness of the cylindrical portion is reduced
Solution Approach 1:
The steering lock device is positioned in a different spatial dimension or orientation that avoids the need for undercutting the cylindrical portion. This dimensional arrangement allows the cylindrical portion to maintain its full stiffness while still preventing overlapping with other members through strategic positioning rather than geometric modification.

AI summary
It is an object of the present invention to provide a steering apparatus for a vehicle mounting a steering lock device to an upper tube by small numbers of constructing parts.A guide supporting mechanism guiding and supporting a upper tube in relation to a lower housing along an axial direction of the upper tube includes a guide bracket portion fixed to the upper tube, and a guide portion mounted in the lower housing to guide and support the guide bracket along the axial direction of the guide tube. A steering lock device locking and unlocking rotation of the upper shaft includes a lock housing guiding a cylinder in back and forth direction, and a lock bracket portion mounted in a shape of grasping the upper tube by the lock housing therewith. The guide bracket and the lock bracket portion are formed to one piece as a whole.
