Vehicle Battery Mounting Load-Receiving Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle battery mounting structures are vulnerable to impact during rear collisions, as the connection beam can break into the battery frame due to insufficient absorption of impact energy.
Innovation Solution
A vehicle battery mounting structure featuring a load-receiving portion between the connection beam and the battery frame, which is inclined and has a higher rigidity than the connection beam, to absorb impact energy by deforming and restrict the movement of the connection beam, thereby minimizing the risk of it breaking into the battery frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the battery is mounted close to the connection beam to save space, then the vehicle structure becomes more compact, but the impact force during rear collision can break the connection beam into the battery frame
Solution Approach 1:
The patent introduces a load-receiving portion as an intermediary component between the connection beam and the battery frame. This mediator component is designed to receive and redirect the impact force from the connection beam away from the battery frame, preventing the harmful effect of the impact while maintaining the compact mounting arrangement.
2Object-affected harmful factors
If the connection beam is allowed to deform to absorb impact energy, then the impact load on the battery is reduced, but the connection beam may move excessively toward the front of the vehicle
Solution Approach 1:
The patent extracts the impact absorption function from the connection beam's primary structural role by introducing a dedicated load-receiving portion. This separate component is specifically designed to handle the impact forces, allowing the connection beam to deform and absorb energy without compromising the overall positional stability of the assembly.
3Strength
If the load-receiving portion is made with higher rigidity than the connection beam, then the connection beam deforms to absorb impact energy, but the load-receiving portion may transfer excessive force to the battery frame
Solution Approach 1:
The patent applies local quality by designing the load-receiving portion with specific rigidity characteristics that are optimized for its particular function. The rigidity is locally adjusted to be higher than the connection beam to ensure proper force distribution, while the overall structure is configured to prevent excessive force transfer to the battery frame through strategic geometry and material selection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The structure effectively reduces the impact load transferred to the battery by allowing the connection beam to deform and absorb energy, minimizing the risk of the connection beam breaking into the battery frame during collisions.
Implementation Method 1
when the connection beam is smashing against the load-receiving portion, the connection beam deforms and thereby absorbs the impact energy

AI summary
In a vehicle battery mounting structure, each sidewall of a bracket body has a load-receiving portion extending obliquely from the vehicle vertical direction upper end of a base portion toward the vehicle vertical direction lower end of a flat wall. The load-receiving portion is located between a rear wall and an intermediate beam. Thus, when the intermediate beam is moving toward the vehicle longitudinal direction front side during a rear collision, or the like, a front wall of the intermediate beam smashes against the load-receiving portion.
