Electric Scooter Side Cover Charging Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric scooters require the rider seat to be opened for battery charging, making the charging process cumbersome and inconvenient.
Innovation Solution
An electric two-wheeled motor vehicle design featuring a side cover with an openable and closeable lid that allows for battery charging without needing to open the rider seat, with a power-receiving connector fixed between the side cover and housing box, enabling charging with the seat closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power-receiving-side connector is disposed below the rider seat in the storage box, then the battery can be charged, but the rider seat must be opened for charging which makes the charging process cumbersome and inconvenient
Solution Approach 1:
The power-receiving-side connector is extracted from the storage box location and repositioned to the side cover location. This allows the connector to be accessible from the side of the vehicle without requiring access to the storage box under the rider seat, thereby eliminating the need to open the rider seat for charging operations.
Solution Approach 2:
The connector access is moved from a vertical dimension (under the rider seat in the storage box) to a lateral dimension (side cover on the side of the vehicle). This dimensional change allows charging to occur without compromising the rider seat position, enabling the seat to remain closed during charging.
2Ease of operation
If the rider seat is opened for charging, then the battery can be accessed, but the rider seat must remain open during charging which may compromise security and convenience
Solution Approach 1:
The power-receiving-side connector is extracted from the storage box location and repositioned to the side cover location. This allows the connector to be accessible from the side of the vehicle without requiring access to the storage box under the rider seat, thereby eliminating the need to open the rider seat for charging operations.
3Ease of operation
If the power-receiving-side connector is disposed between the side cover and housing box, then charging can occur with the rider seat closed, but the connector requires precise positioning to prevent lid movement during charging
Solution Approach 1:
The lid member is equipped with a closed state maintaining mechanism that is activated before charging begins. This mechanism pre-establishes the locked position of the lid, ensuring that the connector remains securely positioned between the side cover and housing box throughout the charging process without requiring high manufacturing precision.
Solution Approach 2:
The closed state maintaining mechanism acts as an intermediary that compensates for positioning tolerances. It ensures the lid remains firmly in the closed position, preventing any movement that could displace the connector during charging, thereby reducing the stringency of manufacturing precision requirements.

AI summary
In an electric two-wheeled motor vehicle including: an electric motor for generating power to drive a rear wheel; a battery for supplying electric power to the electric motor; a rider seat on which a rider seats; a housing box disposed below the rider seat; and a side cover covering the housing box below the rider seat, the electric two-wheeled motor vehicle configured to allow charging of the battery, an opening (118) covered with an openable and closeable lid member (120) is provided in the side cover (48), and a power-receiving-side connector (67) to which a power-supplying-side connector leading to an external power source can be inserted and connected is fixed and disposed between an outer surface of the side cover (48) and the housing box to face the opening (118). Accordingly, it is possible to eliminate the requirement for a rider seat to be opened in charging of a battery and thereby facilitate the charging work.
