In the last mile delivery in the city, traditional electric tricycles often get stuck on slopes due to lack of power. Electric Four-wheel Vehicle is difficult to get through narrow alleys. Coupled with inefficient Electric Tricycle Controller and weak Electric Tricycle Motor, not only is the load capacity limited, but the battery life is also frequently in danger. Even the Electric Tricycle Rear Axle makes strange noises due to frequent heavy loading. These problems cause couriers to receive 5 fewer orders a day, and the loss rate of fresh food delivery soars by 10%.
Our efficient delivery electric freight tricycle is the "urban shuttle tool" that solves the efficiency dilemma! Equipped with a 1200W permanent magnet synchronous motor and an intelligent vector controller, the power is increased by 40% when climbing a slope. With the reinforced rear axle, it can easily cross a 15° slope with a load of 800 catties. The 1.8-meter-long cargo box has a volume of 2.1 cubic meters, which is 30% more than traditional models. The turning radius of narrow alleys is only 3.2 meters, and it can flexibly pass through the alleys in the old city. Actual measurements at Shanghai express delivery outlets show that the cargo capacity of a single vehicle has increased by 50%, the average daily delivery mileage has increased by 25 kilometers, and the motor failure rate has decreased by 60%.
Three keys to performance upgrade
① Power coordination control system: The motor and controller build a data interconnection network, and the torque distribution is intelligently adjusted according to the load in real time, reducing energy consumption by 35%;
② Fast loading cargo compartment: The cargo box is equipped with quick-detachable guardrails and anti-slip textured bottom plates, and the standardized loading and unloading process is completed in 3 minutes, which is 40% more efficient than traditional models;
③ Street fighting traffic plan: The 1.2-meter golden vehicle width is matched with double-wheel differential technology, and there is no need to reverse when meeting in narrow alleys, and the delivery time is improved by 20%.
Tips for senior delivery maintenance
① Three-core joint inspection method: Use a multimeter to detect the voltage of the controller and motor wiring every week, and the rear axle gear oil is forced to be replaced every 2,000 kilometers;
② Load balancing technique: The center of gravity of the cargo is moved back 15 cm, and the left and right load difference is controlled within 5% to avoid unilateral strain of the power system;
③ Time-effective maintenance method: Clean the dust in the motor heat dissipation holes every day, and focus on checking the waterproof sealing components of the controller before the rainy season.
