Vehicle Structure Slider Member Guides Chamber During Side Collision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional vehicle structures, there is a risk of interference between a chamber and an energy storage, such as a battery, during a side collision, as the chamber shifts towards the energy storage, leading to potential damage and instability.
Innovation Solution
A vehicle structure design that includes an energy storage, a chamber positioned on the outer side of the vehicle width direction, and a slider member inclined towards the inner side, which guides the chamber to fall below the energy storage during a side collision, preventing interference. The slider member is fixed between the chamber and the side frame, and a cover member supports the lower side of the slider member to enhance the guiding mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the chamber is arranged on the outer side of the vehicle width direction relative to the energy storage, then the chamber can be positioned away from the energy storage under normal conditions, but during a side collision the chamber shifts toward the inner side and interferes with the energy storage
Solution Approach 1:
The slider member acts as an intermediary component between the chamber and the side frame. It provides a guided path for the chamber to move during collision while preventing direct contact with the energy storage. The slider member mediates the interaction between the chamber and side frame, converting uncontrolled lateral movement into controlled downward movement.
Solution Approach 2:
The invention changes the dimension of chamber movement from purely lateral (vehicle width direction) to a combination of lateral and vertical movement. By introducing the vertical dimension through the inclined slider member, the chamber is guided to move downward as it moves inward during collision, thereby avoiding interference with the energy storage.
2Object-affected harmful factors
If the slider member is inclined toward the inner side in the vehicle width direction toward the lower side, then the chamber is guided to fall below the energy storage during collision, but the slider member must be securely fixed to the side frame to withstand collision forces
Solution Approach 1:
The slider member is pre-installed and secured to the side frame before collision occurs. The fixation structure, including the insertion portion and fastening member, is prepared in advance to withstand the collision forces. This preliminary securing ensures that when collision occurs, the slider member is already in position to guide the chamber safely.
Solution Approach 2:
The fixation structure is divided into separate components: the insertion portion that receives the fastening member, and the fastening member itself. This segmentation allows for easier assembly and ensures that each component can be optimized for its specific function - the insertion portion provides precise positioning while the fastening member provides secure attachment.
3Object-affected harmful factors
If the lower end portion of the slider member is positioned lower than the lower end portion of the energy storage, then the chamber is guided to fall below the energy storage, but the slider member requires additional support structures to maintain its position and function
Solution Approach 1:
The side frame serves multiple functions: it provides the structural framework of the vehicle, supports the energy storage, and anchors the slider member. By making the side frame multi-functional, the invention avoids adding separate support structures specifically for the slider member, thereby reducing overall device complexity while still providing necessary support.
Solution Approach 2:
The support function for the slider member is merged with the existing side frame structure. Rather than creating a separate support system, the invention integrates the slider member support into the side frame, combining multiple functions into a single structural element and simplifying the overall design.

AI summary
A vehicle structure includes a battery, a chamber that is arranged on an outer side in a vehicle width direction of the battery and provided on part of an exhaust pipe through which emission gas from a fuel cell system is emitted outside a vehicle, and a side frame that is arranged between the battery and the chamber in the vehicle width direction and extends in a fore-and-aft direction. A slider member inclined inward in the vehicle width direction toward a lower side of the vehicle is arranged between the chamber and the side frame. A lower end portion of the slider member is in a position lower than a position of a lower end portion of the battery.
