Electric Scooter Battery Compartment Assembly for Anti-Drop Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection between the battery compartment and the frame in existing electric scooters is weak, leading to potential detachment and falling out under impact forces, compromising stability and safety.
Innovation Solution
A battery compartment design featuring a compartment body with a limiting flange that penetrates through the frame opening, secured by a threaded connection and reinforced by a reinforcing rib, ensuring stable mounting and impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the battery compartment is horizontally mounted in the middle of the frame with a complex mounting structure, then the mounting complexity increases, but the connection strength between the battery compartment and the frame becomes low
Solution Approach 1:
The battery compartment is divided into an upper battery compartment and a lower battery compartment that are separable and can be independently mounted. Each compartment has its own mounting structure with limiting flanges, allowing the mounting function to be segmented and simplified while maintaining strong connections through distributed mounting points
Solution Approach 2:
The limiting flange is integrated into the battery compartment structure itself, with the flange forming an integral part of the compartment body. This nesting of the mounting feature within the compartment structure eliminates separate mounting brackets or附件, simplifying the overall mounting system while providing robust mechanical connection through the flange's engagement with the frame
2Reliability
If the battery compartment is mounted to the frame, then the connection provides initial stability, but under overlarge impact force from a rider, the connection tends to loose and the battery compartment falls out
Solution Approach 1:
The limiting flange is designed with a structure that proactively prevents downward displacement of the battery compartment. The flange extends beyond the compartment body and engages with the frame to create a mechanical stop that counteracts impact forces before they can cause detachment, providing preliminary protection against falling out
Solution Approach 2:
The mounting structure combines the limiting flange made from a material with high mechanical strength and rigidity to resist impact forces. The flange's material composition and structural design work together to absorb and distribute impact energy, preventing connection failure under overlarge forces
3Strength
If a limiting flange is added to prevent the compartment body from falling out, then the connection strength improves, but the device complexity increases
Solution Approach 1:
The limiting flange is merged with the battery compartment body to form an integral structure. Instead of being a separate component that needs to be attached, the flange is formed as part of the compartment molding process or through integral shaping, combining the compartment housing and mounting feature into a single unified component that reduces overall structure complexity

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