The present invention relates to an unmanned aerial vehicle with improved battery efficiency, and more specifically, to a technology of a little more extending the flight time of the unmanned aerial vehicle by using the unmanned aerial vehicle′s charging system, and preventing the power of a main battery, which powers each motor for driving a drone, from being completely discharged, thereby improving efficiency according to a battery storage space and extending an expiration date of the battery. That is, the present invention comprises: a main body unit on which a plurality of propellers are installed; a power generation unit which generates electricity since a photovoltaic module is installed on an upper portion of the main body unit; a power storage unit in which electricity generated through the power generation unit is stored, and which is implemented by applying a lithium ion battery; a driving motor which receives electricity from the power storage unit and drives each of the propellers of the main body unit; a direction control unit installed in the main body unit and controlling the output of the driving motor to control a flight direction of the main body unit; and a wireless remote controller which controls the unmanned aerial vehicle from a remote location by using the direction control unit and wireless communication. The power storage unit comprises a main battery and an auxiliary battery. The present invention further comprises: a remaining amount check unit which checks the remaining amount of the power of the main battery; and a power supply control unit which controls the switching to the auxiliary battery when the remaining amount of the power of the main battery reaches 10%.
본 발명은 배터리 효율이 개선된 드론에 관한 것으로서, 더욱 구체적으로는 드론의 자체적인 충전시스템을 이용하여 드론의 비행시간을 좀 더 늘릴 수 있도록 하면서, 드론 구동을 위한 각모터로 전원을 하는 메인배터리의 전원이 완전이 방전되는 것을 방지하여, 배터리 저장공간에 따른 효율성을 높이고 배터리의 사용기한을 늘릴 수 있는 기술에 관한 것이다. 즉, 본 발명은 복수의 프로펠러가 설치되는 본체부와, 상기 본체부의 상부에 태양광 모듈이 설치되어 전기를 생성하는 발전부와, 상기 발전부를 통해 생성된 전기가 저장되며 리튬이온전지로 적용되는 축전부와, 상기 축전부의 전기를 제공받아 본체부의 프로펠러를 각각 회전시키는 구동모터와, 상기 본체부의 내부에 설치되고 구동모터의 출력을 조절하여 본체부의 비행방향을 제어하는 방향제어부와, 상기 방향제어부와 무선통신을 이용하여 원격지에서 조종하는 무선조종기;로 이루어지며, 상기 축전부는 메인배터리와 보조배터리로 구성되고, 상기 메인배터리의 전원 잔량을 체크하는 잔량체크부와, 상기 메인배터리의 전원 잔량이 10%에 도달하였을 때 보조배터리로 전환되도록 제어하는 전원공급 제어부;를 포함하여 이루어지는 것을 특징으로 한다.
