Vehicle Emblem Clutch Mechanism for Rapid Gravity Retraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emblem lifting mechanisms in vehicles are complex, have inadequate descending speeds, occupy excessive space during retraction, and are prone to damage or cause secondary injuries when collided.
Innovation Solution
An emblem lifting mechanism with a clutch that selectively connects and disconnects the emblem body to a driving assembly, allowing the emblem to ascend and descend under gravitational force, featuring a sliding block and pin mechanism for quick descent when disconnected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the emblem body is driven to descend by the driving assembly, then the emblem can retract into the vehicle body, but the descending speed is insufficient and the structure is complex
Solution Approach 1:
The patent extracts the clutch mechanism from the traditional motor-driven descending system. When disconnecting, the emblem body is no longer driven by the complex driving assembly but instead descends freely under gravitational force, achieving rapid retraction with a simple release action rather than complex controlled driving.
Solution Approach 2:
Instead of using the driving assembly to push the emblem down (active driving), the patent inverts the approach by allowing gravity to pull the emblem down (passive descent). The driving assembly's role is reversed from being the primary descending force to merely providing upward support that, when released, enables gravity-driven rapid descent.
2Speed
If the clutch disconnects the emblem body and driving assembly for quick descent, then the emblem can retract rapidly, but the control precision is reduced
Solution Approach 1:
The emblem body is first positioned at the desired location by the driving assembly with full control precision. Only after reaching the target position does the clutch disconnect, allowing gravity to take over for rapid descent. This preliminary positioning ensures that control precision is maintained during the controlled phase before the rapid descent begins.
Solution Approach 2:
The system dynamically switches between two modes: a controlled mode where the driving assembly provides precise positioning, and a free-descent mode where gravity provides rapid motion. The clutch acts as the dynamic switch between these two states, allowing the system to optimize for precision when needed and for speed when retraction is the priority.
3Measurement precision
If the emblem body is continuously connected to the driving assembly, then the emblem can be precisely controlled, but the structure occupies excessive space during retraction
Solution Approach 1:
The clutch mechanism extracts the emblem body from the constraint of continuous driving assembly connection. When disconnected, the emblem body is freed from the space-consuming driving mechanism, allowing it to retract into a compact position within the vehicle body without requiring the driving assembly to occupy space during the retracted state.
Solution Approach 2:
The system segments the emblem body's movement into two distinct phases: a controlled positioning phase where precision is maintained through connection to the driving assembly, and a retraction phase where the clutch disconnects to allow compact storage. This segmentation allows the system to achieve both precision control and compact retraction by separating these functions into different operational states.

AI summary
Provided are an emblem lifting mechanism and a vehicle. The emblem lifting mechanism includes an emblem body, a driving assembly and a clutch. The driving assembly is disposed in a vehicle body of the vehicle. The clutch selectively connects the driving assembly and the emblem body. When the clutch connects the driving assembly and the emblem body, the driving assembly is able to, through the clutch, drive the emblem body to move relative to the vehicle body of the vehicle and support the emblem body, and when the clutch disconnects the driving assembly and the emblem body, the emblem body is able to descend under gravitational force of itself.
