EV Charging Inlet Locking Mechanism Against Connector Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicle charging connectors are prone to separation or theft during charging, as users often leave the vehicle unattended for extended periods, leading to potential safety and security issues.
Innovation Solution
A locking device for electric vehicles that automatically secures the charging connector to the vehicle's inlet unit using an automatic locking module and can be manually released using a smart key in emergency situations, ensuring the connector remains attached during charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the charging connector is left unattended during charging, then the charging process can proceed automatically, but the connector may be separated or stolen
Solution Approach 1:
The locking device is activated automatically when the charging connector is inserted into the inlet unit, engaging the locking mechanism before any potential separation can occur. This preliminary locking action ensures the connector remains securely attached throughout the charging process without requiring user intervention.
Solution Approach 2:
The locking device acts as an intermediary mechanism between the charging connector and the inlet unit, providing a physical connection that prevents separation. The locking mechanism includes a locking protrusion and locking groove that engage to maintain the connection, serving as a mediator that ensures reliable attachment during automated charging.
2Reliability
If a locking mechanism is added to prevent connector separation, then connection stability is improved, but device complexity increases
Solution Approach 1:
The locking device is divided into distinct functional components: a locking protrusion on the inlet unit, a corresponding locking groove on the charging connector, and an actuating mechanism. This segmentation allows each component to perform its specific function while keeping the overall structure manageable and maintainable.
Solution Approach 2:
The locking mechanism is designed to operate automatically without requiring external control or complex actuation systems. When the charging connector is inserted, the locking protrusion and groove engage automatically, and the locking device activates the securing mechanism autonomously, eliminating the need for additional control systems.
3Ease of operation
If the locking device is designed for automatic operation, then ease of operation is improved, but manufacturing complexity increases
Solution Approach 1:
The locking device integrates multiple functions into a single unified mechanism: detection of connector insertion, activation of the locking action, and maintenance of the locked state. By merging these functions into one compact device, the number of separate components is reduced, simplifying both manufacturing and assembly processes.
Solution Approach 2:
The locking device is designed to work with standard charging connectors and inlet units, providing a universal solution that can be applied across different electric vehicle models and charging stations. This multi-functionality reduces the need for model-specific locking mechanisms, thereby simplifying manufacturing and inventory management.

AI summary
A locking device for an electric vehicle is configured to maintain an electrical connection state between an outlet module and an inlet module with an automatic locking module that maintains or releases the electrical connection state between the outlet module and the inlet module by pulling a hook block with respect to the electric vehicle according to whether an outlet unit is coupled on the basis of an inlet unit or by pushing the hook block with respect to the electric vehicle.
