AI Technical Summary
Existing electric bicycle backup charging devices lack buffer protection structures, main/backup power switching connectors, and power status display designs, leading to inconvenience and safety hazards.
An electric bicycle with a backup charging device has been designed, including a main battery unit, a backup battery assembly, a switching assembly, and a display screen. The backup battery is protected by a buffer elastic layer, a dedicated switching connector device is set, and the power status is displayed in real time on the display screen to ensure rapid power supply switching.
It enables stable switching between primary and backup batteries, improves the safety and convenience of electric bicycles in complex environments, extends the driving range, and reduces the risk of circuit failure.
