Multi-rotor frame structure

A multi-rotor frame structure, comprising a main body and a plurality of motor arms and a plurality of support blocks and a plurality of support rods and landing gears and other components, wherein, the main body has two different structure configurations:

• one is a thick plastic plate, thereon with a plurality of arm jack-holes each located at each symmetrical sides positions, and
• the other one is an composition of a plurality of motor arm seats and two sheets of fiberboard, each seat has an arm jack-hole, each seat combine to two fiberboard by double-sided tapes, two sheets of fiberboard bonded sandwiched each motor arm seat at symmetrical position, each arm jack-hole location symmetry, it is for motor arm insert purposes;
• the motor arm is a hollow metal tube at both ends of the head are all closed structure constructs, its one end to the middle section forms a straight long shape, from its middle section to the other end is a smooth long tapered configuration gradually converge, thereof the long tapered end may be deep as nails insert into arm jack-hole of the main body, and thereby forming the main structure of the frame;
• the support block is a thick plastic plate, wherein in the middle portion of the sides of the plate has a through arm-hole which can put on to the motor arm, and
• wherein two rod sleeve-holes are located in the left and right sides of the plate be able to install support rod, thereafter the support rods sleeved to the respective adjacent support block thereof to constitute securing structure of the frame.
