Technical Support & Installation Engineering Guide

The Delivery Box LED Series transforms high-frequency logistics into a dynamic mobile advertising network. Operating on a moving vehicle requires engineering standards far beyond fixed billboards. This guide details the structural, electrical, and thermal protocols necessary for maintaining a fleet of mobile LED displays.

1. Automotive-Grade Structural Integrity

Unlike static screens, the Delivery Box LED must withstand continuous vibration (G-force) and road impacts.

• Anti-Vibration Mounting: The 3-sided LED chassis is built with a reinforced internal honeycomb structure. All internal ribbon cables utilize locking automotive connectors to prevent dislodgement during high-frequency road vibrations.

• Secure Bracket System: We provide universal mounting plates compatible with standard motorcycle and e-bike rear racks. We recommend a 4-point bolting system with nylon-insert lock nuts to prevent loosening over time.

• Aerodynamic Load Balancing: The box’s curvature is designed to minimize wind resistance at speeds up to 60km/h, ensuring the vehicle’s handling and stability remain unaffected during windy conditions.

2. Intelligent Power Management & Battery Protection

One of the primary concerns for fleet operators is the impact on the e-bike’s battery life.

• Low-Power High-Efficiency Drive: The system utilizes custom-voltage power supplies (optimized for 12V-72V DC inputs) with a 92% conversion efficiency, minimizing the drain on the vehicle’s main battery.

• Smart Voltage Cut-off: To prevent stranding the delivery rider, the LED controller features a Low-Voltage Protection (LVP) system. It automatically dims or shuts down the screen if the vehicle’s battery drops below a pre-set threshold (e.g., 15%).

• Ignition Sync: The display is engineered to “Wake on Ignition.” It powers up automatically when the vehicle starts and enters a deep-sleep “Ghost Mode” when the engine is off to prevent parasitic drain.

3. All-Weather Durability & Thermal Control

Delivery boxes operate in tropical heat and torrential rain.

• IP65 Triple-Seal Protocol: The screens are sealed with automotive-grade UV-resistant silicone. The box itself features a double-lip drainage design, ensuring that water running off the screens cannot ingress into the internal electronics or the food compartment.

• Impact-Resistant PC Cover: Each LED face is protected by a high-transparency, anti-UV polycarbonate shield. This protects the pixels from scratches (tree branches, rider handling) and impacts while maintaining high contrast in direct sunlight.

• Passive Airflow Cooling: Utilizing the vehicle’s motion, the box features integrated air intake vents at the front and exhaust ports at the rear, creating a ram-air cooling effect that keeps internal temperatures 20°C lower than the ambient environment during movement.

4. Fleet Management & GPS Synchronization

For large-scale media deployments, content must be location-aware.

• 4G/5G Cloud Connectivity: Every box is equipped with an industrial-grade IoT module. Fleet managers can push localized ads (Geofencing) so that the content changes automatically as the rider enters different districts.

• Real-Time Health Monitoring: The technical dashboard provides real-time data on the temperature, brightness, and online status of every box in the fleet.

• GPS Speed Dimming: To comply with road safety regulations, the brightness can be programmed to increase at higher speeds and dim when the vehicle is stationary at traffic lights to prevent blinding other drivers.

5. Maintenance & Food Safety

• Heat Insulation: The internal food compartment is lined with high-grade thermal insulation to ensure the heat from the LED electronics (which is vented outwards) does not affect the temperature of the delivered food.

• Daily Cleaning: The exterior PC shields are compatible with standard non-abrasive vehicle soaps. The internal compartment is designed with rounded corners for easy sanitization.
