Vehicle Battery Release Mechanism for Fire Pack Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Eco-friendly vehicles, such as electric and hybrid vehicles, face challenges in extinguishing fires within their battery packs due to the internal structure and components, which can lead to rapid fire spread, posing risks to the vehicle and passengers, as conventional fire extinguishing methods are ineffective in completely extinguishing fires within the battery pack.
Innovation Solution
A battery release system that automatically or manually separates the battery pack from the vehicle upon detection of a fire, using a controller, fire detection sensors, and locking devices to release the battery pack from its mounting frame, preventing the fire from spreading to the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fire extinguishing agent is sprayed into the battery pack to extinguish the fire, then the fire may be temporarily suppressed, but the fire cannot be completely extinguished and may spread to the vehicle
Solution Approach 1:
The patent extracts the battery pack from the vehicle as a separate entity when fire is detected. The release system automatically detaches the battery pack from its mounting position on the vehicle, removing the fire source from the vehicle structure. This extraction principle directly addresses the limitation of fire extinguishing agents by physically separating the burning battery pack from the vehicle, preventing fire spread while maintaining the integrity of both the battery pack and vehicle.
2Stability of the object's composition
If the battery pack is securely mounted to the vehicle structure, then the battery pack is stable and fixed, but the battery pack cannot be rapidly removed in an emergency
Solution Approach 1:
The patent implements a dynamic mounting system with release mechanisms that transition between locked and unlocked states. The mounting structure includes locking components that securely hold the battery pack during normal operation, and release components that rapidly detach the battery pack when triggered by fire detection or manual operation. This dynamic design allows the system to adapt between stability and rapid removal based on operational conditions.
Solution Approach 2:
The patent divides the mounting system into separate functional components: mounting frames, locking devices, and release mechanisms. This segmentation allows each component to perform its specific function independently - the mounting frame provides structural support, the locking devices maintain secure attachment, and the release mechanisms enable rapid detachment. This modular approach facilitates both stable mounting and quick removal.
3Ease of operation
If a manual release mechanism is added for battery pack removal, then the system becomes more complex, but the ease of operation for emergency removal is improved
Solution Approach 1:
The patent implements a self-service release system where the battery pack automatically releases from the vehicle when fire is detected. The fire detection sensor triggers the release mechanism without requiring manual intervention, allowing the system to service itself in emergency conditions. This self-service approach simplifies emergency operation while maintaining a relatively simple mechanical release structure.
Solution Approach 2:
The patent designs the release system to perform multiple functions: automatic release upon fire detection, manual release through a release lever, and secure mounting during normal operation. The same mounting frame and locking devices serve both securing and releasing functions depending on the state of the release mechanism. This multi-functionality reduces the need for separate dedicated components for each operation mode.

AI summary
A system can prevent burning of a vehicle or human injury caused by a fire spread from a battery to a vehicle in the event of a fire in the battery of an eco-friendly vehicle. The system can release a battery from the vehicle such that the battery can be separated and removed from the vehicle when a fire occurs in the battery. The system is operated in response to a control signal of a controller detecting the fire in the battery and by manipulation of a driver, and releases a state of the battery mounted to a vehicle body to release the battery from the vehicle such that the battery can be separated or removed from the vehicle.
