[0002] An electric tractor is an electric-driven industrial vehicle, mainly used for towing and moving heavy goods in places such as warehouses, factories or docks. It uses electricity instead of fuel, usually has zero emissions, low noise and relatively low operation and maintenance costs. Electric tractors are suitable for use in indoor and short-distance transportation, providing smooth operation and high-efficiency traction.

[0003] In the port area, due to the close following distance required for the operation of container trucks, rear-end collisions are more likely to occur under adverse weather conditions such as rain, snow, and fatigue driving. The front-end safety prevention measures of the electric container truck main vehicle are insufficient. The original bumper is installed at too low a position and is concave in front of the cab plane. When the container truck is rear-ended, this bumper can only play a certain protective role for the chassis of the container truck and cannot effectively protect the front part of the container truck cab. Expensive components such as headlights, four-in-one assemblies, motor controllers, and steer-by-wire steering lights are integrated in the cab. In case of an accident, it is likely to cause greater losses. In addition, it will also pose a certain threat to the personnel inside the cab, presenting certain potential safety hazards.
