Replaceable Battery Fixing Structure With Inclined Elastic Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing replaceable battery fixing structures in battery-powered vehicles often have insufficient fixing force and require lengthy bolt-fastening operations, leading to inefficient battery replacement times.
Innovation Solution
A replaceable battery fixing structure that uses inclined fixing surfaces and elastic members to secure batteries in both horizontal and vertical directions, facilitated by a hook and operation lever mechanism without bolt fastening, allowing simultaneous and secure attachment/detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bolt or similar fastening structure is used to fix the replaceable battery in the horizontal direction, then the battery can be secured to the housing, but the fixing operation takes a long time and the replacement time increases
Solution Approach 1:
The fixing mechanism is divided into multiple independent elastic members (first elastic members and second elastic members) that can be independently deformed and engaged. Each elastic member independently secures a portion of the battery, allowing for distributed fixing force without requiring complex bolt operations.
Solution Approach 2:
The elastic members utilize elastic deformation to provide dynamic fixing force. When the lid is closed, the elastic members are compressed and store elastic potential energy, which then exerts continuous pressing force on the battery to maintain secure fixation without requiring manual tightening operations.
2Reliability
If a bolt or similar fastening structure is used to fix the replaceable battery, then the battery can be secured, but the fixing operation is complex and time-consuming
Solution Approach 1:
The elastic members are designed to automatically engage with the battery upon lid closure. The deformation and engagement of the elastic members occur automatically through the mechanical action of closing the lid, eliminating the need for manual intervention or complex fastening procedures.

Function Achieved in This Case
Enhances fixing force and simplifies battery attachment/detachment, reducing replacement time and preventing displacement due to vibration.
Implementation Method 1
a plurality of first elastic members and a plurality of second elastic members... Each of the plurality of first elastic members may be attached to the upper corner portion of the distal end of each of the plurality of replaceable batteries and abuts each of the plurality of first fixing surfaces. Each of the plurality of second elastic members may be attached to the lower portion of the proximal end of each of the plurality of replaceable batteries and abuts each of the plurality of second fixing surfaces.

AI summary
A replaceable battery fixing structure includes a housing, and a lid that opens and closes an opening of the housing, and a fixing mechanism that fixes the lid to the housing. The housing includes a first inclined surface on an upper back portion of an interior thereof against which an upper corner portion of the replaceable battery abuts, and the lid includes a plurality of second inclined surfaces that abut a lower portion of a proximal end of the replaceable battery. The first inclined surface is inclined downward toward the back, and the second inclined surface is inclined forward toward the bottom.
