Traveling Device Battery Mount with Slide Rail Damper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery-driven traveling devices face challenges in stabilizing the center of gravity and absorbing vibrations effectively, particularly when the battery is mounted in a way that facilitates maintenance or replacement, while also maintaining a compact vehicle size and low center of gravity.
Innovation Solution
A battery-driven traveling device is designed with a framework section, horizontal slide rails, and dampers positioned above or below the slide rails to absorb vibrations transmitted from the vehicle body to the battery, ensuring a low center of gravity and easy battery access for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the battery is mounted close to the bottom part of the vehicle body to lower the center of gravity, then travel stability is improved, but access to the battery for maintenance or replacement becomes difficult
Solution Approach 1:
The battery mounting system is segmented into a fixed mounting location (close to bottom for stability) and a movable battery unit. The battery can be extracted along the longitudinal direction through the openable rear door, separating the stable mounting structure from the accessible battery position.
Solution Approach 2:
A guide groove and guide protrusion mechanism acts as an intermediary between the fixed mounting structure and the movable battery. This intermediary mechanism enables smooth extraction and insertion of the battery while maintaining the low center of gravity position during operation.
2Reliability
If a damper is provided between the battery and vehicle body to absorb vibration, then battery durability is improved, but vehicle body size increases
Solution Approach 1:
The damper function is merged with the existing battery mounting structure. The damper is integrated into the connection between the battery and vehicle body, combining vibration absorption with the structural support function, thereby avoiding additional space requirements.
Solution Approach 2:
The mounting structure serves multiple functions: it provides structural support, enables battery extraction through the rear door, and incorporates vibration damping. This multi-functionality eliminates the need for separate dedicated damper space.
3Stability of the object's composition
If the battery is mounted near the center of the vehicle body in the front-rear direction for weight balance, then travel stability is improved, but access to the battery becomes more difficult
Solution Approach 1:
The battery is designed to be extractable from the vehicle body through the rear door in the longitudinal direction. This extraction capability allows the battery to be removed from the centrally positioned mounting location without requiring physical access to the center of the vehicle body.
