US Patent 11001443 Drainage system for a delivery autonomous ground vehicle

A delivery autonomous ground vehicle includes several drainage features to keep water away from the package to be delivered and sensitive components. The cargo bay includes dimples to raise the package from the floor of the bay and a drain. Enclosed drain pans beneath elements of the lid also include drains. Water entering from the cooling air inlet holes of discharge holes can drain back through the holes or through the main drain. Overlapping panels inhibit water ingress, but if provided without seals, the water ingress between overlapping panels flows to the main drain.
