Power Source Frame with Abutting Member for Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted power source apparatus protection structures are inadequate in absorbing external forces during collisions, as they either rely on deformation of the floor panel or fixed brackets that can still allow excessive loads to be applied to the battery pack.
Innovation Solution
A protecting structure comprising a frame unit with interconnected frames surrounding the power source apparatus, featuring an abutting member that displaces and abuts onto the vehicle body to absorb external forces, thereby reducing the direct impact on the power source apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the battery is merely fixed to the floor panel, then the fixing structure is simple, but an external force may act on the battery depending on the magnitude of the external force applied to the vehicle
Solution Approach 1:
The patent introduces a protecting frame as an intermediary structure between the battery and the floor panel. This frame absorbs external forces through its abutting member that contacts the vehicle body, preventing direct force transmission to the battery while maintaining a relatively simple fixing structure through the frame's integrated design
2Strength
If the battery pack is fixed to a floor panel by using bolts, then the fixing strength is improved, but an external force may still act on the battery pack depending on the magnitude of the external force applied to the vehicle
Solution Approach 1:
The protecting frame serves as a mediator that absorbs external forces before they reach the battery pack. The abutting member of the frame contacts the vehicle body to absorb shocks, while the battery pack is fixed to the frame with bolts, creating a layered protection system that maintains both fixing strength and external force protection
3Reliability
If the floor panel is formed to be easy-to-deform to absorb shocks, then shock absorption is improved, but no external force may act on the battery depending on the magnitude of the external force applied to the vehicle
Solution Approach 1:
The protecting frame acts as an intermediary shock-absorbing structure between the floor panel and the battery. The frame's abutting member absorbs external forces through controlled deformation and contact with the vehicle body, protecting the battery while maintaining overall structural integrity through its rigid frame design
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
This configuration effectively suppresses the action of external forces on the power source apparatus by transferring the force to the vehicle body, simplifying the fixing structure and preventing excessive loads from reaching the battery pack, thus enhancing protection without complex reinforcement.
Implementation Method 1
the abutting member is displaced in the predetermined direction in response to displacement of the frame unit subjected to the external force in the predetermined direction and the other end of the abutting member abuts on the vehicle body

AI summary
[PROBLEMS] The present invention provides a protecting structure for a power source apparatus capable of suppressing the action of an external force on the power source apparatus when a vehicle is subjected to a shock.[SOLVING MEANS] A protecting structure for a power source apparatus, has a frame unit in which a plurality of frames (21a to 21h) are connected to each other and surround the power source apparatus (30) mounted on a vehicle; and an abutting member (22) connected to the frame unit and extending in a direction in which the abutting member abuts on a vehicle body. The abutting member is arranged so as to extend in a direction in which an external force in a predetermined direction acts on the vehicle.
