Description

Technical Field

[0001] The present invention relates to the field of automation, and in particular to an unmanned food delivery device. Background Art

[0002] With the rapid development of e-commerce and food delivery, consumers have an increasing demand for food and food delivery, especially in the field of fresh food and cold chain delivery. The requirements for delivery timeliness, accuracy and food safety assurance are becoming more stringent. The proposal of unmanned food delivery device aims to solve the problem of manual dependence in the delivery process, realize efficient, accurate and low-cost food transportation through intelligent technology, reduce food safety risks caused by manual operation, and promote the development of food delivery towards intelligence and environmental protection.

[0003] In the existing technology, traditional delivery methods mainly rely on manually driven motor vehicles, electric vehicles or electric tricycles. Its advantage is that the delivery model is mature and can adapt to the transportation needs of different distances and types of goods. At the same time, relying on the existing logistics scheduling system, it can achieve a certain degree of centralized management and resource optimization. In addition, in recent years, some delivery companies have tried to use drones or unmanned vehicles for delivery, which has improved the delivery efficiency to a certain extent and reduced the dependence on manual labor during the delivery process.

[0004] In the prior art, unmanned vehicles usually use solar panels to absorb solar energy as the main energy source to support long-term driving during driving. This design has improved energy utilization efficiency and reduced carbon emissions to a certain extent. However, the fixed design of existing solar panels has obvious shortcomings, that is, the solar panels cannot be dynamically adjusted according to the angle of light during vehicle driving. When the angle of light changes, such as when the sun's altitude changes or is blocked by surrounding buildings and trees, the absorption efficiency of the solar panels will drop significantly, resulting in unstable energy conversion efficiency. In addition, in low-light environments such as cloudy days or at night, the energy supply capacity of fixed solar panels is further weakened and cannot meet the normal operation requirements of unmanned vehicles. This uncertainty in energy supply directly affects the endurance and operational stability of unmanned vehicles, especially in long-distance or high-frequency delivery scenarios, limiting the breadth and flexibility of their practical applications.
