The present invention provides a multi-copter having an arm frame reinforcement function which can firmly couple an arm frame to a body frame to greatly enhance durability. According to the present invention, the multi-copter having an arm frame reinforcement function comprises: a body frame (110) consisting of a pipe having a hollow space formed therein to form the framework of a multi-copter; an arm frame (116) consisting of a pipe having a hollow space formed therein and extended in a width direction (W) to be arranged such that one side thereof crosses a portion extended in a front/rear direction (L) on the body frame (110) and a motor (112) for rotating a propeller in accordance with applied driving power is mounted on the other side thereof; an arm joint (117) inserted into the hollow space at a position facing the body frame (110) on the arm frame (116); a body joint (118) inserted into the hollow space at a position facing the arm joint (117) on the body frame (110); and a first fastening means (119a) inserted through a portion in which the body joint (118), the arm frame (116), and the arm joint (117) are overlapped with each other to fix the arm joint (117) on the body joint (118).

    본 발명의 특징에 따르면, 내부에 중공이 형성된 관체로 이루어져 멀티콥터의 골조를 형성하는 바디프레임(110); 내부에 중공이 형성된 관체로 이루어지고 폭방향(W)으로 연장되어 상기 바디프레임(110) 상에서 전후방향(L)으로 연장된 부위에 일측이 교차되도록 배치되며 타측에는 인가되는 구동전원에 따라 프로펠러(111)를 회전시키는 모터(112)가 장착된 암프레임(116); 상기 암프레임(116) 상에서 상기 바디프레임(110)과 대향하는 위치의 중공 내부에 삽입되는 암조인트(117); 상기 바디프레임(110) 상에서 상기 암조인트(117)와 대향하는 위치의 중공 내부에 삽입되는 바디조인트(118); 및 상기 바디조인트(118), 암프레임(116) 및 암조인트(117)가 상호 중첩된 부위에 관통삽입되어 암조인트(117)를 바디조인트(118)에 고정시키는 제1체결수단(119a);을 포함하는 암프레임 보강기능이 구비된 멀티콥터가 제공된다.
