Solution Overview
Problem
Saddle-type electric vehicles face challenges in preventing stress on connectors due to vehicle oscillations, leading to terminal wear and inefficient connection processes when mounting or detaching batteries.
Innovation Solution
Incorporating an elastic member to support the battery and a mechanism with a user-operable operation member that switches the connector state between unlock and lock positions, allowing the connector to follow oscillations during travel and ensuring secure connection when mounting the battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the battery is supported via an elastic member to reduce impacts from vehicle oscillations, then the battery and connector are protected from damage, but the connector cannot maintain stable electrical connection during vehicle travel
Solution Approach 1:
The connector on the vehicle side is designed to be movable in the vertical direction, allowing it to dynamically adapt to battery oscillations during vehicle travel. The connector can move upward to follow the battery when it oscillates, maintaining continuous electrical contact. During battery mounting/detachment, the connector transitions to a fixed position to ensure stable connection. This dynamic adaptability resolves the contradiction between impact protection and connection stability.
2Reliability
If the connector on the vehicle is fixed to ensure stable connection during mounting, then connection reliability improves, but stress is applied to connector terminals during vehicle oscillations
Solution Approach 1:
The connector on the vehicle side is designed with movable capability in the vertical direction to dynamically adapt to battery oscillations during vehicle travel. When the battery oscillates upward, the connector can move upward accordingly, preventing stress concentration on the terminal. During battery mounting or detachment operations, the connector transitions to a fixed position to ensure stable electrical connection. This dynamic adaptability resolves the contradiction between connection stability and terminal stress prevention.

AI summary
A vehicle includes a battery supported by an elastic member. The vehicle is provided with a connector that is electrically connected to a connector on the battery. The connector on the vehicle is switched between an unlock state in which the movement of the connector on the vehicle is allowed to follow the oscillation of the battery, and a lock state in which the movement of the connector on the vehicle is restricted. Accordingly, it is possible to prevent a stress from being applied to the connector on the battery and the connector on the vehicle when a vehicle is travelling, and it is possible to smoothly connect the connector on the battery and the connector on the vehicle when a user mounts the battery on the vehicle.
