AI Technical Summary
The complex speed bumps in the community place high demands on the passability and stability of unmanned delivery vehicles. Traditional unmanned delivery vehicles have a low chassis design, making them prone to ground contact damage. Furthermore, the rigid suspension system cannot effectively buffer impacts, resulting in severe vehicle vibration and cargo tilting or falling off, affecting delivery safety and efficiency.
The modular design of the vehicle frame and cargo box, combined with self-locking hydraulic cylinders and spring shock absorbers, allows it to adapt to complex terrain by raising the wheels. By operating multiple delivery vehicles in series, the self-locking hydraulic cylinders and spring shock absorbers improve obstacle-crossing ability and stability while reducing computing power consumption.
It has enabled unmanned delivery vehicles to operate stably in complex terrain, improving delivery efficiency and safety, and reducing the operating costs and scheduling workload of delivery vehicles.
