Vehicle Battery Securing Assembly for Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrically operated motor vehicles face challenges with securing vehicle batteries to the vehicle body, leading to low-frequency vibrations due to the battery's heavy weight and two-dimensional extension, which complicates initial assembly and later removal for servicing, and existing solutions like continuous openings are not age or corrosion resistant.
Innovation Solution
A securing assembly for vehicle batteries that uses a detachable securing element and device, allowing material bonding, form fitting, or force locking without a flange, enabling initial assembly without passenger compartment access and easy removal for servicing, utilizing an adhesive bond or screw connections for secure attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the vehicle battery is secured using an encircling securing flange with screws, then the battery is firmly attached to the vehicle body, but low-frequency vibrations occur during vehicle operation due to the battery's heavy weight and two-dimensional extension
Solution Approach 1:
The patent transitions from traditional two-dimensional securing (flange on battery rim) to three-dimensional securing by attaching the securing element to the battery housing cover (top surface). This vertical dimension addition allows the securing force to act through the housing cover rather than just at the rim, reducing vibration transmission to the vehicle body.
2Ease of manufacture
If continuous openings are provided in the battery housing for securing, then the battery can be attached to the vehicle body, but the housing becomes vulnerable to dirt and moisture penetration with high sealing costs
Solution Approach 1:
The patent extracts the securing function from the battery housing structure itself and places it on a separate securing element that attaches to the housing cover. This separation allows the housing to remain sealed and intact while providing secure attachment points through the removable securing element with integrated sealing.
Solution Approach 2:
The securing element acts as an intermediary between the battery housing and the vehicle body. It provides the necessary attachment points and sealing function without requiring openings in the battery housing, thus protecting the housing from moisture and dirt penetration while enabling secure mounting.
3Volume of moving object
If the vehicle battery is arranged beneath the passenger compartment, then the vehicle structure is compact, but the battery height is limited and access to the passenger compartment is restricted during initial assembly
Solution Approach 1:
The securing element is pre-installed on the battery housing before the battery is placed in the vehicle. This preliminary action allows the battery to be positioned and secured from the vehicle underbody without requiring access to the passenger compartment, simplifying the assembly process while maintaining compact vehicle architecture.
4Stability of the object's composition
If the vehicle battery is securely attached to the vehicle body, then vehicle stability is improved, but removal of the battery for servicing or replacement becomes difficult
Solution Approach 1:
The securing element provides a dynamic securing solution that adapts to different operational states: during normal operation, it firmly attaches the battery to the vehicle body for stability; during maintenance, it can be easily detached to allow battery removal. The detachable nature of the securing element enables this dynamic behavior.

AI summary
A securing assembly secures a vehicle battery on a vehicle body, and includes a securing element for securing to a housing of the vehicle battery and a securing unit for detachably securing to a body part of the vehicle body. The securing element and the securing unit are configured so as to be integrally, interlockingly or force-lockingly connected to one another when bringing the vehicle battery into a mounting position.
