Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an opening and closing device for an automatic airport of an unmanned aerial vehicle and a single-door automatic airport. Background Art

[0002] With the deepening of the understanding of the application value of unmanned aerial vehicles, unmanned aerial vehicles have shown a rapid development trend in the consumer, industrial and military markets, and unmanned aerial vehicles are used more and more in many fields. However, the flight time of unmanned aerial vehicles has become the biggest bottleneck restricting the development of unmanned aerial vehicles. Although lithium-ion batteries are currently the batteries with the best comprehensive performance in the market, they still cannot fully meet the flight time requirements of unmanned aerial vehicles. Therefore, the charging problem of unmanned aerial vehicles must be considered during the use of unmanned aerial vehicles.

[0003] Automatic airports for storing unmanned aerial vehicles and charging and replacing batteries for unmanned aerial vehicles have emerged. However, for existing large and medium-sized automatic airports for unmanned aerial vehicles, their hatch opening and closing structures are basically composed of two hatches and two driving structures, etc., which are bulky and costly. Because there are two hatches, there will be a gap between the two hatches when the hatches are closed. In the case of heavy rain, rainwater will flow into the airport from the gap. To solve the problem of rainwater flowing into the airport from the gap, it is necessary to add waterproof sealing strips, diversion grooves and other structures. Adding structures means increasing costs, and at the same time, the waterproof sealing strips will age and fail, resulting in gaps. It is only a matter of time before rainwater flows into the airport from the gap. Moreover, the two hatches will occupy a large amount of space when in the open state. Summary of the Utility Model
