Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of replacing a battery module of an unmanned airplane and an unmanned airplane,

The present invention relates to a method of replacing a battery module of an unmanned aerial vehicle and an unmanned aerial vehicle, and more particularly, to a method of replacing a battery module of an unmanned aerial vehicle A battery module of an unmanned aerial vehicle and an unmanned aerial vehicle capable of easily and quickly replacing the battery module by fixing the battery module, minimizing the waiting time for replacing the battery module, Replacement method.

Unmanned aerial vehicles (also commonly referred to as "drones") refer to airborne vehicles capable of flight and coordination by induction or automatic control of radio waves while the pilot is not on board. Unmanned aerial vehicles have been developed and used mainly for military purposes such as reconnaissance and attack, but they are also being developed and used for civil or industrial purposes such as leisure, image shooting, delivery and disaster observation.

For example, United States Patent Application Publication No. US2015 / 120094A1 (Patent Document 1), entitled " UNMANNED AERIAL VEHICLE DELIVERY SYSTEM, " filed by Amazon Technologies, Inc. on April 30, 2015, To a variety of destinations. According to the structure of U.S. Patent Application Publication No. US2015 / 120094 A1, the cargo can be rapidly delivered through the unmanned airplane.

Meanwhile, a conventional unmanned airplane, particularly a civilian or industrial unmanned airplane, generally operates by a battery module in most cases. Particularly, the conventional unmanned aerial vehicle used for delivery of freight such as courier has a disadvantage of high power consumption, and the battery module must be replaced according to power consumption. For example, rather than increasing the number of unmanned airplanes, the unmanned airplane is operated by replacing the battery module while operating a proper amount of unmanned airplane, so that the battery module is replaced more frequently as the usage of the unmanned airplane increases . Since the battery module is mostly manually replaced by an operator, it takes a lot of cost and time to replace the battery module of the unmanned aerial vehicle.

To improve this, a method of automatically charging a battery module of an unmanned aerial vehicle is being developed.

Korean Patent No. 10-1732713 (Patent Document 2) entitled " Drone Filling System "filed on December 24, 2015 and registered on Apr. 26, 2017 by Yang Jun- Discloses a charging system in which electric power is supplied to a battery module of an unmanned aerial vehicle after being placed on a seat portion. However, according to the configuration disclosed in Korean Patent No. 10-1732713, since the UAV has to wait until the charging is completed while the UAV is landing on the charging device for charging, there is a disadvantage that the operating time of the UAV is remarkably reduced .
