Vehicle Lock Ice Breaking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle doors often become frozen due to rain and snow, making it difficult or impossible to open them using traditional mechanisms, especially in vehicles with hidden or canceled external handles.
Innovation Solution
A lock mechanism with an integrated ice breaking mechanism, comprising a lock ring, engagement plate, and ice breaking arm, which drives the engagement plate to rotate and break the ice, allowing the door to be opened.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a door actuator is mounted to push the door by a certain distance, then the frozen door can be opened, but the system complexity and costs increase
Solution Approach 1:
The ice breaking mechanism is integrated into the existing lock body structure, combining the ice breaking function with the door locking mechanism. The swinging ice breaking arm, ice breaking pull rod, and tensioning wheel are incorporated within the lock body, sharing structural space and reducing overall system complexity while maintaining the ability to open frozen doors
2Reliability
If the engagement plate rotates to break ice, then the door can be opened in frozen conditions, but the mechanical structure complexity increases
Solution Approach 1:
The engagement plate serves dual functions: it acts as both the locking engagement component and the ice breaking tool. When the tensioning wheel rotates, it drives the ice breaking pull rod, which causes the engagement plate to rotate about shaft I, allowing the groove on the engagement plate to engage with the lock ring and push the lock ring to break ice and open the door
Solution Approach 2:
The ice breaking mechanism components are nested within the existing lock body structure. The swinging ice breaking arm is mounted on shaft VII within the lock body, the ice breaking pull rod rotates on shaft VIII relative to the swinging ice breaking arm, and the tensioning wheel on shaft IV drives the entire mechanism, creating a compact nested arrangement that minimizes space requirements and structural complexity

AI summary
A lock mechanism with an ice breaking mechanism. The lock mechanism is composed of a lock ring, an engagement plate, a pawl, a shaft, an engagement plate driving rod, a pawl release lever, a release lever, a support, a swinging claw, a tensioning wheel, a cable, a pulley, a limiting member, a supporting arm, a fixed shaft, a pull rod, a spring, a swinging ice breaking arm, an ice breaking pull rod, and the like. The lock mechanism is provided with the ice breaking mechanism. The ice breaking mechanism may be started to push a vehicle door away by a specific distance, so as to assist in manually or automatically opening the door, which improves the degree of satisfaction of customers.
