Electric Scooter Battery Compartment Flange for Impact-Stable Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery compartments in electric scooters have complex mounting mechanisms with low strength connections, leading to potential disconnection and fall-out under impact forces.
Innovation Solution
A battery compartment design featuring a compartment body with a limiting flange that abuts against the frame, reinforced by a rib structure, and secured with threaded connections, ensuring stable lapping and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the battery compartment is complexly mounted to the frame, then the connection strength should be improved, but the mounting complexity increases and the joint stability still deteriorates under impact force
Solution Approach 1:
The battery compartment is divided into the compartment body and the limiting flange as separate functional elements. The limiting flange is specifically designed to bear impact forces while the compartment body houses the battery, allowing the mounting structure to be simplified without compromising overall strength
Solution Approach 2:
The limiting flange acts as an intermediary element between the compartment body and the frame. It specifically engages with the frame to absorb and distribute impact forces, eliminating the need for complex mounting mechanisms while maintaining connection strength
2Ease of operation
If the battery compartment uses a simple mounting structure, then the mounting ease is improved, but the joint stability deteriorates when subjected to impact force
Solution Approach 1:
The limiting flange is provided with localized engagement features (such as engagement protrusions fitting into engagement grooves on the frame) that concentrate impact force resistance at specific points. This allows the overall mounting structure to remain simple while achieving high joint stability where needed
Solution Approach 2:
The limiting flange combines structural rigidity for force bearing with geometric features optimized for stable engagement with the frame. The flange's design integrates both mounting simplicity and impact resistance through its composite geometric structure
3Stability of the object's composition
If the limiting flange is designed with engagement features, then the joint stability is improved, but the device complexity increases
Solution Approach 1:
The limiting flange merges multiple functions into a single component: it provides structural support, absorbs impact forces, and ensures stable positioning through engagement features. This integration eliminates the need for separate mounting brackets or additional stabilizing elements, reducing overall device complexity while maintaining joint stability

AI summary
A battery compartment (100), a battery compartment assembly and an electric scooter are provided. The battery compartment is used for an electric scooter, and includes a compartment body (1) and a limiting flange (2). The electric scooter includes a frame (5) with an opening (501), and the opening (501) runs through the frame (5) in an up-down direction. The compartment body (1) is configured to penetrate through the opening (501), and the limiting flange (2) is arranged to an outer side wall of the compartment body (1) and configured to abut against the frame (5) to prevent the compartment body (1) from falling out of the opening (501) downwards.
