Micro-Mobility Battery Mount Rail for Secure Fast Swaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Servicing a fleet of micro-mobility transit vehicles, such as electric kick scooters and bicycles, poses significant capital investment and labor burdens, particularly in dynamic transportation matching systems.
Innovation Solution
The development of propulsion battery mount assemblies with a mounting rail featuring a contoured surface for alignment with the vehicle frame, and securing assemblies that eliminate overhang, facilitating secure battery pack installation and reducing vandalism and maintenance costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional battery mounting systems are used, then battery installation is simple, but security against vandalism is poor and maintenance burden is high
Solution Approach 1:
The mounting system is divided into separate components: a mounting rail attached to the vehicle frame, and a battery pack with integrated securing features. This segmentation allows the security functions to be concentrated in the mounting rail while keeping the battery pack design relatively simple.
Solution Approach 2:
The securing assemblies are nested within the mounting rail structure, with the battery pack fitting into the space between them. The securing assemblies are positioned to engage with the battery pack from the sides, creating a nested configuration that provides security without requiring external mounting hardware.
2Object-affected harmful factors
If secure battery mounting is implemented, then vandalism is reduced, but assembly complexity increases
Solution Approach 1:
The mounting rail combines multiple functions into a single component: structural support for the battery pack, mounting surface for securing assemblies, and alignment features through contoured surfaces. This merging reduces the total number of parts and simplifies the assembly process despite providing robust security.
Solution Approach 2:
The battery pack assembly includes integrated securing features that automatically engage with the mounting rail when the battery is installed. The contoured surfaces provide self-alignment, and the securing assemblies are designed to be mounted on the battery pack itself, allowing the battery to participate in its own securing process.
3Productivity
If fleet servicing is improved, then labor burden is reduced, but system complexity increases
Solution Approach 1:
The mounting system is designed to accommodate dynamic servicing operations, allowing battery packs to be quickly removed and replaced during fleet maintenance. The securing assemblies can be rapidly engaged and disengaged, enabling efficient battery replacement without complex tooling or procedures.
Solution Approach 2:
The mounting rail is pre-installed on the vehicle frame during manufacturing, and the securing assemblies are pre-positioned on the battery pack. This preliminary preparation allows fleet servicers to simply attach or detach battery packs without requiring complex assembly procedures or specialized tools during routine servicing.

AI summary
Systems and methods related to propulsion battery mount assemblies for micro-mobility transit vehicles are disclosed. For example, in an embodiment the battery mount assembly includes a mounting rail having a first side comprising a contoured surface configured to align with a complementary contoured surface of a frame of a micro-mobility transit vehicle and a second side comprising a battery mounting surface opposite the first side and configured to receive a first securing assembly and a second securing assembly entirely disposed thereon and separately spaced to receive a battery pack therebetween. The battery mount assembly may be installed on the frame of a micro-mobility transit vehicle to assist in expedient replacement of battery packs that electrically power the micro-mobility transit vehicle.
