Movable Battery Housing Angular Pivot Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric two-wheeler designs face inconvenience in battery recharging and safety due to permanently housed batteries, and structural compromise with swappable batteries, which require users to physically access and replace batteries.
Innovation Solution
A chassis with a movable battery housing system that allows angular movement under the seat, enabling battery replacement without opening the seat, combined with a locking system for secure closure, allowing for easy access and maintenance by authorized personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is permanently housed inside the body of the electric two-wheeler, then the structural integrity is maintained, but the user needs to find charging docks or install charging infrastructure and park the vehicle for recharging, causing inconvenience
Solution Approach 1:
The battery system is segmented into a removable battery unit and a battery housing. The battery can be detached from the housing and replaced independently, allowing users to swap batteries without charging infrastructure while maintaining structural integrity when the battery is installed.
Solution Approach 2:
The battery mounting system incorporates movable components including a movable battery housing that can transition between closed and open positions, and a movable battery that can be inserted and removed. This dynamic design enables easy battery replacement while maintaining structural integrity during normal operation.
2Ease of operation
If the battery is made replaceable by opening seats or footrests, then users can replace the battery when depleted, but this compromises safety and structural integrity and requires additional tools or keys
Solution Approach 1:
The battery system is divided into a removable battery unit and a battery housing that remains permanently installed in the vehicle. The housing includes a cover that can be opened to access the battery, separating the replacement function from structural components like seats and footrests.
Solution Approach 2:
A dedicated battery housing cover acts as an intermediary component between the user and the battery. The cover can be opened to access the battery for replacement, providing a safe and structured access point without compromising vehicle structural integrity or requiring tools or keys.
3Ease of operation
If the battery housing is made movable and openable, then easy battery replacement is enabled, but the structural integrity may be compromised
Solution Approach 1:
The battery housing is segmented into a main housing body and a separate cover. The cover is made movable and openable to provide access to the battery, while the main housing body remains permanently installed and maintains structural integrity. This segmentation allows the access function to be isolated to a non-critical component.
Solution Approach 2:
Different parts of the battery housing have different properties: the cover is made movable and openable for access, while the main housing body maintains permanent installation and structural strength. The locking mechanism provides localized securing at the cover-battery interface without compromising overall structural integrity.

Function Achieved in This Case
Facilitates quick, user-friendly battery replacement while maintaining structural integrity and safety, allowing outsourced battery swapping without user intervention.
Implementation Method 1
at least one pivot hinge mounted on the first bar and coupled to a front side of the movable battery housing, wherein the at least one pivot hinge is configured to support the movable battery housing
Implementation Method 2
at least one support member configured to support the movable battery housing, wherein a first end the at least one support member is coupled to the seat support section and a second end of the at least one support member is coupled to the movable battery housing
Implementation Method 3
a locking means mounted on the second bar and configured to detachably connect with the securing means in the closed position to lock the battery in the closed position

AI summary
Embodiments of the present disclosure relate to a chassis for a two-wheeler. The chassis includes a first downtube and a second downtube and a battery mounting system. The battery mounting system includes a movable battery housing configured to house a battery under a seat of the two-wheeler and move between a closed position and an open position, at least two support members configured to support the movable battery housing, and at least one pivot hinge coupled to a front side of the movable battery housing and supporting the movable battery housing. The at least two support members and the at least one pivot hinge are configured to enable an angular movement of the movable battery housing with respect to a seat axis between the open position and the closed position, thereby enabling replacement of the battery located under the seat of the two-wheeler, while maintaining a closed seat position of the seat.
