AI Technical Summary

Technical Problem

The current power distribution boards of existing agricultural or heavy-duty drones cannot meet the high current requirements and are susceptible to rain corrosion in open-air environments, leading to overheating, short circuits and safety hazards.

Method used

The design incorporates bent copper busbars, power distribution partitions, and a multi-layer waterproof structure. The copper busbars, formed by bending a single piece of copper alloy, carry the current. Combined with a centrally symmetrical partition and a multi-layer sealed waterproof design, the electrical connection is guaranteed to be safe and waterproof.

Benefits of technology

The current handling capacity of the circuit board has been improved, the contact resistance and heat generation have been reduced, the power output stability and safety of the drone have been enhanced, and normal operation in rainy environments has been ensured.
