Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing structure of electric two-wheeled vehicles with integrally formed central processing units and power control parts inside the rear arm is prone to vibration-induced shock and heat-related durability issues, necessitating enhanced shockproof and heat-resistant designs.
Innovation Solution
The EV controller and inverter parts are formed in a divided manner, with the EV controller attached to the outer periphery of a synthetic resin storage box below the seating seat, directly connected to the battery, and the inverter placed below a low step board, providing improved vibration protection and eliminating the need for high-voltage conductors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the central processing unit and power control part are integrally formed and arranged inside the rear arm, then the device complexity is reduced, but the shockproof property deteriorates due to direct vibration from the road surface
Solution Approach 1:
The control device is divided into separate modules: the central processing unit is placed in a control device housing, while the power control part is positioned in the rear arm. This segmentation allows each component to be protected appropriately - the CPU is shielded from vibration while the power control part remains close to the motor for efficient power management.
2Device complexity
If the central processing unit and power control part are integrally formed, then the device complexity is reduced, but the heat resistance deteriorates because the power control part generates high temperature
Solution Approach 1:
By separating the power control part from the central processing unit, the patent allows the power control part to be positioned in the rear arm where it can be thermally managed independently, away from the heat-sensitive CPU components, thus improving overall heat resistance.
3Object-affected harmful factors
If the EV controller is attached to the storage box, then the vibration protection is improved, but the device complexity increases due to separate mounting structures
Solution Approach 1:
The control device housing is integrated with the storage box structure, merging the CPU housing and storage box into a unified component. This integration provides vibration protection for the EV controller while simplifying the overall structure by eliminating separate mounting brackets and fastening mechanisms.
